Background: The proposal that MALDI-ToF mass spectrometry could be used as a direct, rapid and affordable diagnostic tool in clinical laboratory medicine has moved from a theoretical possibility to a reality for Microbiology. Several studies have proposed the application of this technology in obstetric and gynaecological evaluation of patients. In particular, we have proposed that the adoption of MALDI-ToF mass spectrometry in examination of maternal pregnancy urine samples for the detection of Downs syndrome. Methods: A retrospective collection of 20 Down Syndrome and 100 non-aneuploid pregnancy urines at 12 to 14 weeks gestation, collected in 2007-2008 from high risk pregnancy cohorts, were examined by MALDI-ToF mass spectrometry in the mass/charge range between 1000 and 100000 m/z. Normalisation of spectral data was defined using mass bins of 100 m/z expressed as a percentage of the total ion count of the mass spectra from 2000 to 11000 m/z. Of the ninety 100 m/z bins, forty-six were identified as m/z bins at which statistically significant differences in spectra occurred between Downs and control/non-aneuploid samples. Based on the differences and variance, for values at these bins, weighted scores of the probability of being Downs were assigned. Comparative algorithms consisting of various mass bins were tested for ability to distinguish Down syndrome from non-aneuploid pregnancy. Results: Although various algorithms could distinguish Downs from non-aneuploid controls, it was found that gestational age was a confounding factor and that if separated into gestational age matched cohorts the ability to distinguish the groups improved dramatically e.g. whilst a 19 bins algorithm separated 100% of Downs from non-aneuploid pregnancies for a 9% false positive rate in the mixed gestational ages group; a two bin algorithm distinguished 100% of Downs for a 6% false positive rate for the 12 weeks gestational age pregnancies. Conclusion: Normalised MALDI-ToF mass spectra, at 2000 to 11000 m/z, of maternal urine gives rise to gestational age specific screening tests algorithms for Downs’s syndrome.

Background: Mechanical chronic neck pain is very common musculoskeletal dysfunction among people, manifesting one or more pain-induced movements and disability impairments. Clinical guidelines suggest passive cervical mobilization and thoracic manipulation as manual therapy interventions. Mulligan concept has positive effect in patients with lumbar and thoracic spine mechanical chronic pain. Study objective was to investigate possible clinical effects of Mulligan techniques in patients with cervical pain according to pain and disability status. Methods: forty participants diagnosed with mechanical chronic cervical pain, randomly assigned into experimental and control group. NAG, SNAG and self-SNAG joint mobilization in a nine-sessions protocol implemented to the study group, while SHAM-Mulligan techniques applied to control group. Self-reported questionnaires Numeric Pain Rating scale (NPRT) and Neck Disability Index (NDI) were used for the measurement of pain and disability levels respectively. Possible Interactions among Factors (TIME X GROUP) and simple effects in three-time measurements of pre, post and one-month follow-up concerning NDI and NPRS variables, were detected with Mixed-ANOVA test. Results: Baseline scores of pain and disability resulted in no differences between groups. A significant Group and Time factors interaction founded and simple main effects analysis showed that Mulligan concept-group had significant improvement in post-intervention NPRT and NDI scores (p<.001), compared to baseline scores. Follow-up also differed compared to post-treatment score (p<.001). SHAM-Mulligan control group had no significant differences in dependent variables at any level of TIME factor (p>.001). Significant differences were found between groups according to second and third measurement phase (p<.001). Conclusion: Our findings suggest that Mulligan concept techniques improve symptoms of pain and disability in chronic mechanical neck pain patients in short and mid-term effect level. Summary: Mobilization techniques of SNAGs, NAGS and self-SNAGs reduces pain and improve function in patients with mechanical neck pain. Taken into consideration the safety and simplicity of application, future studies are encourage to examine the underline mechanism of action.

Background: Klebsiella pneumoniae is a bacterial species that often causes infections in humans. Infections occur most frequently in hospitalised or immunocompromised patients and are treated with antimicrobials. In recent decades, K. pneumoniae has developed significant resistance to many antimicrobials. Objective: The main goal of this study was to determine the frequency of resistance of isolated K. pneumoniae strains from urine samples of hospital patients and outpatients, and to find evidence of ESBL strains and their resistance to certain antibiotics. Methods: During the study period, Klebsiella pneumonia was isolated from the urine samples of 430 patients. The procedure for processing of urine samples, identification, susceptibility toward antimicrobials and evidence of ESBL strains were carried out according to the recommended standards. Results: Of the total K. pneumoniae isolates, 153 (35.6%) were isolated from hospital patients and 277 (64.4%) from outpatients. Strains isolated from hospital patients were resistant to each tested antibiotic. ESBL strains were detected in 169 (39.30%) samples, 92 (60.13%) from hospital patients and 77 (27.8%) from outpatients. Conclusion: Strains of K. pneumoniae isolated from the urine of hospital patients and outpatients have developed significant resistance against all tested antibiotic substances. A higher occurrence of ESBL strains was observed in hospital patients than in outpatients. ESBL strains were resistant to all penicillins and almost all cephalosporins. Highly effective antimicrobials were amikacin, colistine, carbapenem and fosfomycin. The best therapeutic results were achieved when patients were treated with fosfomycin and imipenem.

The sequence-independent, single-primer amplification (SISPA) enables the random amplification of nucleic acids, allowing the detection and genome sequencing of different viral agents. This feature of SISPA method provides evidence for application of it in monitoring the presence of adventitious RNA viruses in cell cultures. We evaluated SISPA method for the detection of a challenge RNA virus representing adventitious agent in cell cultures. Besides, by optimizing the SISPA method in our laboratory, we found false-positive results on negative control lanes in electrophoresis gels. To investigate the sources of contamination, false-positive results of SISPA were cloned into Escherichia coli cells, sequenced, and phylogenetically analyzed. This data revealed that the SISPA method can be used as an adjunct method to confirm the absence of unexpected adventitious RNA viruses in cell cultures. The phylogenetic analysis of SISPA contaminant sequences showed that the false-positive results were caused by nucleic acid amplification of commercial cDNA synthesis kit reagents, probably tracing back to expression plasmids and host ribosomal sequences, used for the production of enzymes. Therefore, laboratories using random amplification methods must be constantly aware of the potentials of such contaminations, yielding false-positive results and background noise in the final NGS reads.

The novel coronavirus 2019-nCoV has become a bane to mankind and spread worldwide and infected many people. Thus, there is an urgent need of a cure for the severe pneumonia disease caused by this virus. In this study, In silico comparative analysis has been done for HIV protease inhibitors on coronavirus 3CLpro protein which has shown the major interactions and common amino acid residues involved in interactions. The amino acid interaction analysis has revealed two amino acids ARG4, LYS5 to be the major amino acids targets among selected ligands. The binding energy analysis has also revealed Cobicistat as one of these best suited ligand for 3CLpro.

Radiation of different wavelengths can kill living organisms, although, the mechanism of interactions differs depending on their energies. Understanding the interaction of radiation with living cells is important to assess their harmful effects and also to identify their therapeutic potential. Temporally, this interaction can be broadly divided in three stages – physical, chemical and biological. While radiation can affect all the important macromolecules of the cells, particularly important is the damage to its genetic material, the DNA. The consequences of irradiation include- DNA damage, mutation, cross-linkages with other molecules, chromosomal aberrations and DNA repair leading to altered gene expression and/or cell death. Mutations in DNA can lead to heritable changes and is important for the induction of cancer. While some of these effects are through direct interaction of radiation with the target, radiation can interact with the surrounding environment to result in its indirect actions. The effects of radiation depend not only on the total dose but also on the dose rate, LET etc. and also on the cell types. However, action of radiation on organisms is not restricted to interactions with irradiated cells, i.e. target cells alone; it also exerts non-targeted effects on neighboring unexposed cells to produce productive responses; this is known as bystander effect. The bystander effects of ionizing radiations are well documented and contribute largely to the relapse of cancer and secondary tumors after radiotherapy. Irradiation of cells with non-ionizing Ultra-Violet light also exhibits bystander responses, but such responses are very distinct from that produced by ionizing radiations.

Gingival recession is defined as apical migration of the gingival epithelium leading to the exposure of root surface. There are many surgical procedures for treating gingival recessions and the main goal is to cover the exposed tooth surface by soft tissue augmentation. The surgical techniques performed for root coverage has their own advantages and limitations. The surgical technique used for managing the gingival recession is the major factor that determines the outcome and the long term result of the procedure. The most common surgical technique in treating the isolated gingival recession is the lateral pedicle graft and the surgical technique with highest percentage of root coverage is the connective tissue graft. This case report deals with the management of an isolated gingival recession with lateral pedicle and connective tissue graft. The outcome of the procedure was excellent having complete root coverage.

Venom has a very complex and exclusive nature which has been introduced by recent advances in omics technologists. These methods have revealed a new insight into venom studies as venomics. Envenoming by venomous animals is a global concern due to the distribution of important medical species around the world. Treatment of envenomed victims is dependent on accurate and fast identification of animal species with different detection methods. In recent years, new methods have been introduced based on molecular and immunological techniques. Precise diagnosis of species of venomous animals is an essential factor for treatment with specific antivenoms. Venomics and antivenomics data sets help in the selection of specific antivenoms or production of novel antivenoms with greater efficacies.

Objective: During aging, skin undergoes structural, cellular and molecular changes, which not only alter skin mechanical properties but also biological and physiological functions. Structurally the epidermis becomes thinner, the dermal epidermal junction flattens and the extra-cellular matrix component of the dermis is disorganized and degraded. The dermis is composed of two compartments: The Reticular dermis is the deepest and thickest part while the upper layer, the papillary dermis, which is much thinner and is in close contact with epidermis, plays an important role in the structure and function of the skin. We have recently shown that the papillary dermis was preferentially affected by skin aging because the activity of fibroblasts in this region was especially altered as a function of age. The purpose of this study was to investigate the capacity of a flax extract as anti-aging component. Method: We investigated the capacity of a flax extract to stimulate or restore the activity of papillary fibroblasts from young and old donors in cultured monolayers and in reconstructed skin. Several biological markers of extracellular matrix homeostasis and mechanical properties were investigated. Results: The tested flax extract seemed to improve parameters known to change with age: I/ In monolayers after treatment the number of aged fibroblasts increased II/ In reconstructed skin the flax extract appears to positively regulate some biological activities; particularly in aged fibroblasts where the deposition of laminin 5, fibrillin 1, procollagen I were increased in the dermis and the secretion of specific soluble factors like MMP1, MMP3 and KGF were regulated to levels similar to those observed in young fibroblasts III/ Mechanical properties were improved particularly for elastics parameters (R5, R2 and R7). Conclusion: The flax extract is a promising anti-aging compound. The treatment of aged papillary fibroblasts resulted in a return to a younger-like profile for some of the studied parameters.

Statement of problem: Provisional restorations play a critical role in the success of restorative treatment so they must maintain their integrity in the oral environment throughout the diagnostic and restorative phases. Purpose: The aim of this study was to compare and evaluate the hardness of four different materials used fabrication of interim restoration. Material and methods: Ten samples with dimensions of 10mmx10mmx2mm were fabricated from four interim materials (DPI, Tempron, Protemp 4 and Transcan). Hardness of samples was measured using Fischer scope hardness tester. Result: The highest mean hardness was found in Heat polymerizing acrylic resin group. ANOVA test indicated F value to be 2201.01 which was highly significant (p < 0.001). Conclusion: Heat polymerizing resin and bisacrylics may be considered in a long term provisional fixed prosthesis.

he presence of bifid mandibu¬lar canals is an unusual but not rare occurrence. The mandibular canal containing the inferior alveolar artery, vein, and nerve, originates from the mandibular foramen and terminates at mental foramen [1-4]. In radiology, mandibular canal’s appearance has been described as “a radiolucent dark ribbon between two white lines”[5]. White and Pharoah defined it as “dark linear shadow with thin radiopaque superior and inferior borders cast by the lamella of bone that bounds the canal” [6]. Understanding of its anatomic variations is very important due to its clinical implications in various oral and maxillofacial treatments like removal of wisdom teeth [7], mandibular implant placement [8], in bilateral sagittal split osteotomy procedures and during fixation of mandibular fractures. Presence of bifid or multiple mandibular canals forces the clinician to change the treatment plan. Ignoring this variation can cause several complications intra or postoperatively or even result in failure of treatment. For instance a bifid canal if ignored during surgical removal of third molar or dental implant placement can cause prolonged pain even after administering local anesthesia and also severe bleeding if the accessory canal is encroached [2]. Bifid mandibular canals may originate from the mandibular foramen independently or might bifurcate from a single canal during its course inside the mandible [8]. Bifid mandibular canals have been by classified by multiple authors according to anatomical location and configuration, on panoramic radiographs and computerized tomography. According to Carter and Keen [1], inferior alveolar nerve can be arranged as- Type I: single large bony canal, Type II: canal is lower down in the mandible and Type III: canal separates posteriorly into two large branches. Nortje, et al. [9] gave patterns of duplication as- Type I: duplicate canals from a single mandibular foramen which can be of same size/ lower canal smaller/ upper canal smaller. Type II: short upper canal up to the second molar areas. Type III: two canals from separate foramina, joining at molar area and Type IV: supplemental canals joining the main canals in the retromolar areas. This report describes a case of a bilateral Bifid Mandibular Canal suspected by a panoramic radiograph and confirmed by a CBCT prior to a dental treatment.

Related the physio-pathological process of COVID-19 disease it is interesting to focus to the aspect. Played by interaction of Sars-Cov-2 protein with integrins of human epithelial pulmonary cell. A bio molecular approach help in to deeply verify the involved factors and the results of this Activation RGD mediated. Of Great interest also the relationship with some vaccine strategy followed by the various pharmaceutical industry. The results of this work will be useful to think modification in some vaccine increasing the global safety and related some rare ADR.

The rise in all-cause and cardiovascular mortality and hospitalization rates among the hemodialysis (HD) patients after the long weekly inter-dialysis interval is very impressive. In fact, there is an additional long-term morbidity risk besides this acute rise in mortality and hospitalizations that can be expected from the weakly exaggerated pre-dialysis peaks of the less risky hemodynamic and biochemical parameters. An approach for eliminating these long weekend inter-dialysis intervals is through the provision of the hemodialysis sessions on every other day (EOD) basis, regardless of the week days. This is likely to be both practical and cost-effective. Such EOD schedule can be introduced easily beside the ongoing thrice weekly HD schedule without disturbance of the HD unit work. The availability of EOD schedule would provide a healthier and cost-effective alternative schedule for those patients who can’t tolerate the weekend intervals and for those looking for maintaining their long-term health on the option of hemodialysis. In fact, with available data, medical staff is expected to encourage all patients to shift their HD to the EOD schedule.

Background: In line with the so-called “embodiment concept”, human bodily experience is characterized by the immediate feeling that our body is localized in a certain position in space and that the self is localized within these body limits. Aim: To verify in a cohort of patients affected by unilateral spatial neglect (NSU) secondary to cerebrovascular damage the possible correlation between a comprehensive neuromotor/neuropsychological rehabilitative treatment and the modification of body representation. Setting: A rehabilitation institute for the treatment of neurological gait disorders and neuropsychological failures. Methods: 12 patients (7 males, 5 females; mean age 60 ± 2yy) affected by NSU secondary to cerebral stroke and recovered in the Neurological Rehabilitation Section of the Clinical Institute Città di Brescia were recruited for the aim of this study. In accordance with our inclusion criteria we recruited 4 patients affected by ischemic stroke and 8 patients affected by haemorragic stroke; 9 patients of our study group arrived from a coma state period. Recruited patients underwent at time T0 (hospitalization day) to a functional impairment evaluation (Motricity Index = MI; Trunk Control Test = TCT; Functional Ambulation Category = FAC) and to a neuropsychological evaluation (Behavioural Inattention Test = BIT; Representional drawing; Personal Neglect evaluation scale); each evaluation was repeated in the same way at time T1 (intertime between 2 and 4 months after hospitalization) and time T2 (inter time between 5 and 6 months after hospitalization). At time T0 each patient began an individualized integrated (motor and neuropsychological) rehabilitative treatment course. Results: In all patients recruited a statistical significant modification was observed for the MI LL left, the TCT and the FAC; no significant statistical modification was observed for the MI UL left, the MI UL and the MI LL right. The t-test showed a significant statistical modification of the personal neglect evaluation scale while no significant statistical modification was defined for the spontaneous human figure drawing test proceeding from time T0 to time T1. The spontaneous drawing of the human figure showed an individual different trend and modification in all patients recruited. A correlation analysis was made comparing the mean value of all motor scales (G1) with the mean value of all neuropsychological scales (G2) and no statistical significant correlation was observed between G1 (T0) and G1 (T1), G1 (T0) and G2 (T0), G1 (T0) and G2 (T1), G2 (T0) and G1 (T1), G2 (T0) and G2 (T1), G1 (T1) and G2 (T1). A second correlation analysis was made comparing all single motor scales with the neuropsychological scales, for the group made by 12 patients and the group made by 5 patients. For the group made by 12 patients, we observed the subsequently significant correlations: MI UL left (T0) correlates with MI LL left (T0); MI LL left (T0) correlates with MI LL left (T1); MI UL left (T1) correlates with MI LL left (T1); MI LL left (T1) correlates with FAC (T1); TCT (T1) correlates with FAC (T1). For the group made by 5 patients, we observed the subsequently significant correlation: TCT (T2) correlates with FAC (T2). In the group made by 12 patients, the mean amelioration of the time related normalized (T0-T1) motor scales is equal to 49% while to 63% was observed for the neuropsychological scales. The mean amelioration of the neuropsychological scale proceeding from time T0 to T1 is equal to 26% with an increase equal to 57% proceeding from time T1 to T2. The neurocognitive amelioration can be observed especially between the 5th and 6th month from the ischemic cerebral damage with a mean increase from 26% to 57%. Conclusions: It would certainly make sense to treat patients with NSU from the neuropsychological point of view in the long term and from the neuro-motor point of view in the first 3-4 months after stroke; in all this, we cannot exclude that an improvement of the visuo-spatial exploration, emphasized by the neuropsychological treatment, can positively influence also patient’s motor outcome.

Objective: The purpose of the study was to evaluate if there is a link between salivary pepsin levels and tooth erosion. Also, to determine if gastroesophageal reflux disease (GERD) is responsible for much of the tooth erosion seen by dentists. Background: Pepsin is only produced within the stomach. If found within other parts of the body [for example within saliva or sputum samples], the only mechanism by which that would be possible is via the reflux of gastric contents. One of the causes of dental erosion is thought to be due to direct contact between tooth surfaces and acidic substances and digestive enzymes present in gastric refluxate. GERD is a common condition, with its prevalence seemingly trending higher in recent decades. It is reportedly a known cause of tooth erosions. From the hypothesis, there was an expectation to see patients with dental erosions to have pepsin detected [and perhaps at high levels] and to see patients without dental erosions to have no or low levels of pepsin. Method: Three saliva samples were collected [on waking and 2 post-prandial] from 50 anonymous participating patients (26 females, 24 males) from a single dental practice. Extra information was collected related to lifestyle, Reflux Symptom Index (RSI – reflux questionnaire) and tooth erosions. These samples were analyzed for the stomach enzyme pepsin using the validated medical device Peptest. Results: There was no correlation between positive pepsin levels and the presence of tooth erosion during this study. There was a statistical difference between the on waking pH vs. positive pepsin levels and post prandial pH vs. positive pepsin levels. The average pH was lower for on waking and post-prandial samples with positive pepsin, suggesting that the saliva was acidic and gastric reflux had occurred. Conversely, the average pH was higher for on waking and post-prandial samples with negative pepsin. There was no statistical difference between pH vs. tooth erosion in the on waking and post- prandial. Conclusion: Patients identified as having tooth erosion did not have higher levels of pepsin detected, suggesting that pepsin was not associated with dental erosion in these patients.

Related the need to search new strategy in vaccine design in order to reduce also some rare effect like trombosys for some registered products it is interesting the role played by the SPIKE RGD domain. The binding with molecules like Fibronectin is a process that must to be deeply investigated. A better understanding in this process can be used to improve safety of the new generation of COVID vaccine. The rare effect like thrombosis recognized by regulatory agency produced a modification of technical data sheet of some vaccine so the phenomena Is interesting to be more investigated. Spike protein and its domains are involved in producing pathological effect of the COVID-19 disease. What it is interesting is that some pathological effect of this pathology are similar to some rare side effect produced by some COVID-19 vaccine classes. After a review of interesting literature related this topics is submitted an experimental projects able to verify in vitro the spike procoaugulant property.

Introduction: The phimosis condition is characterized by the inability to retract the foreskin on the glans, making it impossible to expose them. Surgical treatment, although effective, has been questioned by the risk to which the patient is exposed. Therefore, we have opted for the use of topical corticosteroids to resolve this pathology. Goals: To compare the effectiveness of Dexamethasone and Hyaluronidase + Betamethasone Valerate associated with preputial massage in the treatment of infantile phimosis, the degree of regression of phimosis, the time needed to achieve complete efficacy, possible adverse reactions, long-term outcome and parental adherence to treatment in children attending a specialized service in Blumenau, Santa Catarina. Materials and methods: Controlled clinical trial, quantitative, non-blind, prospective and randomized sample analysis through the analysis of 523 patients. Results: After 1 month of treatment, 435 patients presented some degree of regression and 63 children were referred to surgery. The success rate in this period was 45.8% in boys who were taking Hyaluronidase + Betamethasone Valerate and 49.8% in those who used Dexamethasone. In the late evaluation, 398 children reached grade 0, and 213 used Hyaluronidase + Betamethasone Valerate and 185, Dexamethasone; 39 patients were referred to the postectomy. Adherence to treatment was similar in both groups. The average time for degree 0 to be reached similar in both. Conclusion: Both topical corticosteroids were effective in the resolution of phimosis. However, in the evaluation after the first month and in the regression, Dexamethasone proved to be more effective. The time to resolution of the condition was similar for both. The surgical procedure was taken when there was no clinical improvement. No adverse effects were reported in both groups.

Behavioral dentistry is an interdisciplinary science, which needs to be learned, practiced and reinforced in the context of clinical care and within the community oral health care system. The objective of this science is to develop in a dental practitioner an understanding of the interpersonal, intrapersonal, social forces that influence the patients’ behavior. The clinician must acquire knowledge to develop appropriate behavioral skills with an improved quality of communication and management of patients. Behavior dentistry also teaches to develop a recognition and understanding that the body and mind are not separate entities and focuses on patients’ social, emotional and physiological dental experiences. Behavior is an observable act. It is defined as any change observed in the functioning of an organism. Learning as related to behavior is a process in which experience or practice results in relatively permanent changes in an individual’s behavior. Self-perceptions of dental-facial appearance begin with aesthetic values shared within families and based generally on social norms, but that they may be strongly influenced by peer values and specific experiences of individual children, particularly those involving social responses. Theories incorporating concepts of social comparison and self-efficacy suggest that individuals evaluate themselves in comparison with others in their social environment. Children who perceive themselves to be attractive will reflect those perceptions in their behaviors and generally will receive confirming social responses. The comparison group may express an attractiveness norm that reflects negatively on the individual’s behavior. This, in turn, can affect the individual perceived sense of self-efficacy or adequacy within that group and lead to behaviors that reflect more negative beliefs about the self, thereby inviting still more negative social responses. Patient cooperation is the single most important factor every dentist must contend with. Major considerations are • Regularity in keeping appointments • Compliance in wearing removable appliances • Refraining from chewing hard and tenacious substances that are likely to distort or damage the teeth or crowns • Maintenance of oral hygiene. Laxity in following these instructions may lead not only to compromised treatment but also to slow progress of treatment, loss of chair time and frustration. What may be more interesting to the Dentist than the shaping of self-perceptions in the shaping of behavior that will ensure a successful result of treatment, that is, the patient’s adherence to prescribed routines for self-care and other regimens during Dental treatment. It is helpful in this regard to know that most patients expect improved dental-facial appearance as an outcome of treatment, but there is much more to know about factors influencing cooperation. Poor motivation can also contribute to non-compliance. The regulatory loop requires a motivational system to adjust behavior to coincide with the recommended regimen. A patient may recognize that the regimen is not being followed and yet simply not be motivated to correct the discrepancy. Poor motivation can also result from a lack of concern over the long-term health consequences of one’s behavior and/or a lack of belief in the treatment. Cognitive approaches that emphasize the personal relevance of the regimen or address misconceptions about the treatment may enhance motivation. Several approaches may be useful in treating poor compliance. Providing incentives or rewards for compliant behavior might be a useful strategy to enhance motivation. The cause of noncompliance is multifactorial and strategies to improve compliance must be tailored to fit each situation. Current Dental research focuses on a critical aspect of the feedback; specifically, the input received by the comparator that quantifies the actual amount of adherent behavior. Likewise, Patients, parents, and clinicians need a way to ascertain this information.

Ginseng extracts are often used as adaptogen to improve mental performances and well being, helping to overcome stress. Thus, in our times a lot of ginseng extracts are continuously produced and sold into commercial channels. Both Asian and Korean red ginseng (Panax ginseng) and American ginseng (Panax quinquefolius) are the most extensively used and researched. Both Panax ginseng and Panax quinquefolium contain different types of saponins, also known as ginsenosides, which are the substances that give ginseng medicinal properties. Human and animal studies showed that ginseng extracts can also have hypoglycemic effects. The mechanisms by which ginseng reduces blood glucose levels are unclear; some mechanisms have been proposed to explain its hypoglycemic effect, especially modulating effects on insulin sensitization and/or insulin secretion and regulating actions on digestion and intestinal absorption. We describe a case of hypoglycemia by ginseng in type 2 diabetic patient treated with oral hypoglycemic agents. Although, in order to provide better assessments of a sure anti-diabetic efficacy of ginseng, larger and longer randomized controlled clinical trials will be required, in our case we think that we have enough evidence to believe that the cause of hypoglycemia was ginseng. Obviously, this report should not be taken as a proof of the hypoglycemic effect of ginseng, nor it wants to be a suggestion to use ginseng in the treatment of diabetes; instead, it wants to be an alert for patients and clinicians to avoid hypoglycemia in daily clinical practice.

Calcium is the most common element in the tooth’s structure. In addition, calcium is one of the elements that are effective in maintaining dental health. As a result of calcium deficiency, the tooth becomes brittle and begins to rot. Calcium deficiency usually occurs in acidic beverage consumption and during canal treatment. A study was conducted to determine the degree of calcium removal in the root canal dentin after 17% EDTA, 17% EGTA, 15% EDTAC and 1% tetracycline-HCl treatment; later with or without 2.5% NaOCl [1]. Extracted single-rooted human teeth were bisected longitudinally and the root halves (n = 100) were isolated with nail varnish, leaving the root canal exposed. The samples were immersed in the test solutions for 1 and 5 minutes, after which the amount of calcium ion (Ca2+) release into the solutions was determined by flame photometry. The calcium ions (Ca2+) present in hydroxyapatite crystals are one of the main inorganic elements of dentin [2]. It has been reported that some chemicals used for endodontic irrigation are capable of causing alterations in the chemical composition of dentin [3-6]. MethodsDetermination of calcium in the tooth’s structure is very important. Calcium determination, Flame Emission Spectrofometry and inductively coupled plasma optical emission spectrometry (ICP-OES) methods can be performed. These methods can be analyzed in a short time without interference effects. In both methods, the calcium in the tooth is stimulated and the emission intensity it emits is measured as it becomes basic. These emission intensities are directly proportional to the calcium concentration. Also, in these methods, calibration graph or standard addition method is used for calcium determination. The roots were then bisected longitudinally, and the pulp tissue was removed with a toothbrush. All root halves (n = 100) were dehydrated in a sterilizer at 120 °C until they reached a fixed weight, as verified by consistent readings using a precision scale (Sartorius, Gotingen, Germany; precision = 0.0001 g). Thereafter, the specimens were covered with two consecutive layers of nail varnish, leaving the root canal surface exposed. The samples were randomly distributed into the following treatment. Groups: Group 1: 2.5% NaOCl Group 2: 17% EDTA Group 3: 17% EGTA Group 4: 15% EDTAC Group 5: 1% Tetracycline-HCl Group 6: 17% EDTA _ 2.5% NaOCl Group 7: 17% EGTA _ 2.5% NaOCl Group 8: 15% EDTAC _ 2.5% NaOCl Group 9: 1% Tetracycline-HCl _ 2.5% NaOCl Group 10: Distilled water (negative control) In each group, the specimens were immersed in a magnetic stirrer bath containing 10 ml of test solution for 1 and 5 minutes. In groups 1 and 10, the same samples (n = 10) were used for 1- and 5-minute treatments. Calcium is measured between 10 and 1000 ppm (mg/L) with Flame emission intensity. Calcium at a lower concentration cannot be measured. Inductively coupled plasma optical emission spectrometry (ICP-OES) is a widely used method recently. ICP-OES is an advanced high-end method of flame emission spectrophotometer. In this method, the energy source required for excitation is provided by plasma and its temperature is between 4000 and 10000 ⁰C. There is a certain wavelength of light to which each element is stimulated. The wavelength of the light used for calcium is 455,531 nm. At this wavelength, a calibration graph is prepared from standard solutions of calcium. Calcium in the tooth is measured using the calibration chart. The sensitivity of this method is high. Calcium analysis in ppm (mg/L) and ppb (µg/L) concentration can be analyzed with ICP-OES. In this method, the analysis takes minutes. Therefore, it is used in routine analysis. ConclusionUsing these methods, you can easily analyze the calcium found in the structure of the tooth. Also, disinfectant like hypochlorite used during canal treatment increases the calcium release of the tooth. Therefore, the released calcium can also be analyzed using these methods. Here, each sample takes at least 5 measurements and gives the results in accordance with the scientific representation.
