Regenerative medicine is a modern approach of dermatological treatment, using Epidermal Cells of the interfollicular epidermis (ESCs) for their effect in skin regeneration in chronic ulcers and burns, melanoma, vitiligo, junctional epidermolysis bullosa. Intraepidermal injections of autologous epidermal cell suspension can be a new and very promising treatment for many other cutaneous disorders as non-scarring alopecia (Alopecia Areata, Androgenic Alopecia) or scarring alopecia (Lichern Plano Pilaris alopecia, Discoid Lupus Erithematosus alopecia), anti-aging therapies. The intraepidermal injection of an autologous epidermal cell suspension is a simple, fast and safe surgical procedure: a small, thin portion of the epidermis of the patient undergoes a treatment where a suspension with all the cells collected from the epidermis and cultured for 7 days is injected into the skin. Our preliminary study shows that a suspension contains a significant number of viable cells that survive at day 7 in culture. Our research is ongoing and is focusing on the typing of the different cells in the suspension and evaluation of the presence and the nature of stem cells.

Like many tropical countries, Sudan has ample biomass resources that can be efficiently exploited in a manner that is both profitable and sustainable. Fuel-wood farming offers cost-effective and environmentally friendly energy solutions for Sudan, with the added benefit of providing sustainable livelihoods in rural areas. This article provides an overview of biomass energy activities and highlights future plans concerning optimum technical and economical utilization of biomass energy available in Sudan. Results suggest that biomass energy technologies must be encouraged, promoted, implemented, and fully demonstrated in Sudan.

Between 2003 and 2011, 17 patients with heart failure were treated with stem cells as part of our Foundation’s Regenerative Medicine program. In several centers and countries 4 with ischemic cardiomyopathy of which 3 were surgically implanted with autologous bone marrow stem cells (ABMSC) plus bypass surgery. One patient was treated with hyperbaric medicine plus bypass surgery. Patients with idiopathic cardiomyopathy were implanted surgically with 2 different types of stem cells. Ten patients were implanted with stem cells derived from human fetuses (HFDSCs) and three patients with autologous bone marrow stem cells (ABMSC). The ejection fractions of the coronary artery bypass graft off pump OPCAB (control group) versus coronary artery bypass group off pump OPCAB plus stem cell transplantation were as followsin the entire serie: preoperative, 30.7% +/- 2.5% compared to 29.4% +/- 3.6%; 1 month, 36.4% +/- 2.6% versus 42.1% +/- 3.5%; 3 months, 36.5% +/- 3.0% vs. 45.5% +/- 2.2%; And 6 months, 37.2% +/- 3.4% versus 46.1% +/- 1.9% (p <0.001). The first patient performed at our center in Argentina in this series is alive and asymptomatic 15 years after implantation, and the rest of this series we do not have current data. A patient without visible vessels in the anterior wall of the left ventricle was treated with 18 hyperbaric chamber sections from one hour at 1.4 AT. After creating angiogenesis, the patient was operated on receiving 2 grafts (mammary and venous) without extracorporeal circulation in the anterior descending artery and diagonal artery. The preoperative ejection fraction was 33% at 90 months of follow up the ejection fraction was 58%. The patient at 90 months was asymptomatic. Of the idiopathic heart disease group, nine patients underwent median sternotomy, and received human fetal stem cells (HFDSCs from ectopic pregnancy or spontaneous abortion, three patients received autologous bone marrow stem cells ABMSC) and 1HFDSCs for Minimally Invasive Surgery. Patients with HFDSC, compared to baseline, improved: The mean (±SD) NYHA class decreased from 3.4 ± 0.5 to 1.33 ± 0.5 (P = 0.001); Mean EF increased 31%, from 26.6% ± 4.0% to 34.8% ± 7.2% (p = 0.005); the yield in ETT increased 291.3%, from 4.25 minutes to 16.63 minutes (128.9% in metabolic equivalents, 2.45 to 5.63) (P <0.0001); the mean LVEDD decreased 15%, from 6.85 ± 0.6cm to 5.80 ± 0.58cm (P <0.001); the mean performance on the 6-minute walk test increased 43.2%, from 251 ± 113.1 seconds to 360 ± 0 seconds (P = 0.01); the mean distance increased 64.4%, from 284.4 ± 144.9m to 468.2 ± 89.8m (P = 0.004); and the mean score in the Minnesota congestive HF test decreased from 71 ± 27.3 to 6 ± 5.9 (p <0.001). Kaplan-Maier’s probability of survival at 40 months was 66%. No rejection or cancer was observed at follow-up, in this series follow-up was discontinued at 4 years. In idiopathic patients receiving autologous cells by Mininvasive technique preoperative NYHA was 3.6 (+/- 0.70) 6 months after receiving stem cell therapy. The mean value of the functional class was 1.9 (+/- 0.90) (p <0.005). ) showing marked clinical improvement. The preimplantation ejection fraction was 28% (+/- 3.6%) and at 6 months 44% (+/- 4.7%) (p <0.005). There was a similar change in ventricular diameters: After 6 months LVESV went from 50mm (+/- 3.3) to 42mm (+/- 4.5) (p <0.05). Two of the three patients in this group received re-synchronization therapy; one died at 10 years and 4 months, another at age 11 and another one alive at 12 years of the implant. More experience should be performed with different techniques and cells to find the appropriate treatment in this type of patients.

The intention of the present work is to validate an easy, better and reasonable approach for estimation of amoxicillin trihydrate in tablet formulation by opposite segment(reverse phase) HPLC –UV with advanced conditions and parameters for habitual use in Rwanda well known board in pharmaceutical laboratory in order to check if no substandard or counterfeit amoxicillin has entered in our country that can result in antimicrobial resistance, treatment failure which can be a chief difficulty on public health. an easy, selective, precise, speedy, specific, and correct reverse phase HPLC UV-seen technique has been verified for the dedication of amoxicillin, in addition that is a cost-effective technique for the established method, monobasic potassium phosphate (KH2PO4) used as buffer and methanol and had been used as a mobile section in the ratio 95:5 respectively.

To repair articular cartilage (AC) defects in osteoarthritic patients, one approach is to engineer three-dimensional grafts with physicochemical properties similar to endogenous AC. Such grafts can be grown in bioreactors that provide environmental conditions favoring chondrogenesis. Studies show mechanical stimulation during the culturing process greatly enhances development of functional engineered grafts. A review of literature on bioreactor options reveals a lack of capacity to simultaneously stimulate cells with a combination of shear stress and oscillating hydrostatic pressure, both of which are important parts of the in vivo AC environment. It is hypothesized that combining both forces in a new bioreactor design will contribute to better AC tissue growth. In this paper, we provide a brief review of bioreactors and describe a new computer-controlled perfusion and pressurized bioreactor system, and the novelty of its control programming features for service in a host of applications. We briefly summarize results on synergistic effects in employing perfusion, oscillating hydrostatic pressure in a scaffold free environment and with the addition of encapsulation for inducing chondrogenesis. We further describe efforts to modify the newly developed system to include a continuous flow and pressurized centrifugal mode to enhance further the capabilities for inclusion of very high shear stresses. Applications for several other cell and tissue engineering approaches are discussed. 

One of the factors of assisted reproduction technology (ART) success is an adequate growth and development of endometrium. At the end of follicular phase of menstrual cycle endometrium reaches its greatest thickness. It is believed that there is a critical limit of endometrial thickness beyond which the implantation of embryo is unlikely or impossible [1-5]. In practice of ART programs ultrasound measurement of endometrial thickness is used to evaluate uterine lining growth. Scientific literature is debatable as to what thickness of endometrium should be considered optimal, some researchers emphasize the negative impact of “thin endometrium” on the success of ART programs [1-12], while others do not agree [6,7,9]. Nevertheless, when endometrial thickness in ART program does not exceed 6 mm the chance of pregnancy occurring is very low (Kumbak B, et al. 2009). 

Forebrain GABAergic neurons, the main inhibitory type of neuron in the cortex and hippocampus, represent a highly heterogeneous cell population that has been implicated in the predisposition to epilepsy and the onset of seizure. Earlier attempts to restore inhibition and reduce seizure in animal models of epilepsy have been carried out using embryonic basal forebrain tissue as source of immature GABAergic progenitors in cell-based therapies, with promising results. For therapeutic strategies this approach appears unrealistic, while the use of pluripotent stem cells to obtain immature GABAergic neurons opens new and promising avenues. Research on neural stem cells and pluripotent stem cells has greatly advanced and protocols have been established to efficiently direct progenitor cells to differentiate towards the GABAergic lineage. However, being highly heterogeneous, these neurons are difficult to be fully represented in vitro. Better knowledge on the expressed gene profiles, at single cell level, and the differentiation trajectory of these neurons will consent a more precise monitoring of the differentiation steps. Here we review the current literature about how to obtain and characterize genuine inhibitory neurons, how these can be grafted in animal models (and one day possibly in human) and which diseases could potentially be targeted and the efficiency of therapeutic outcome. The main obstacles that need to be overcome are: a) choice of an appropriate animal model, b) availability of human cells prone to GABA differentiation, c) the full representation of all IN subtypes, their proportions and their physiological activities, d) how to monitor them on the long-term after transplant.

Natural killer cells represent the first line of defense against infections and tumors and can be derived from various sources including: bone marrow, peripheral blood, specific types of human stem cells, and certain cell lines. The functions of natural killer cells are influenced by: several cytokines, activating and inhibitory receptors, as well as other immune cells such as dendritic cells and mesenchymal stem cells. Natural killer cells are attractive candidates for adoptive cellular therapy in patients with hematologic malignancies and solid tumors in addition to recipients of various forms of hematopoietic stem cell transplantation as they enhance antitumor effects without causing graft versus host disease. Several clinical trials have shown safety and efficacy of natural killer cell products obtained from autologous as well as allogeneic sources and used in conjunction with cytotoxic chemotherapy, monoclonal antibodies and novel agents. The following review, which includes extensive literature review on several aspects of natural killer cells, will give particular attention to: the rising role of natural killer cell therapies in patients with malignant hematological disorders, solid tumors and in recipients of stem cell therapies; preparation and manufacture of natural killer cell products; challenges facing the utilization of this form of cellular therapy including evolution of resistance; and maneuvers that can be employed to enhance the efficacy of natural killer cell therapies as well as suggested solutions to resolve the remaining challenges.

The oocyte is the female gamete that contributes not only half of the genetic material but also all of the cytoplasm to the zygote, supplying the transcripts, proteins, mitochondria and other components necessary for early embryonic development. The intrinsic oocyte quality is one of the main factors affecting the embryo yield, the implantation rate and the rate of healthy offspring. It is obvious that a fertilized oocyte must reach the blastocyst stage within 6–9 days in the proper culture conditions to have a significant chance of inducing a pregnancy and producing an offspring. The ability to sustain the first week of embryonic development is clearly influenced by the follicular status from which the oocyte is obtained indicating that this developmental potential is inherent within certain oocytes. Since most early embryos that do not reach the blastocyst stage are blocked at or close to the maternal to zygotic transition (MZT)-stage, which occurs at the eight-cell stage in cattle, one could speculate that incompetent oocytes fail to appropriately activate the embryonic genome. Oocyte selection based on glucose-6-phosphate dehydrogenase (G6PDH) activity has been successfully used to differentiate between competent and incompetent bovine oocytes. Recently, molecular regulation of genes regulating biological process of Brilliant Cresyl Blue staining (BCB) selected oocytes and embryos was investigated to explain their variation in quality and developmental potentiality. This short review will highlights some of these efforts that have been done in this interesting area of research.

We present a case of hypocomplementemic urticarial vasculitic syndrome (HUVS) who developed severe renal failure requiring ICU-level care. Our patient is a 66-year-old man who presented with abdominal pain, rash, confusion, oliguria, and shortness of breath. He was found to be in acute renal failure with leukocytosis and elevated lactate. Work-up for infectious, autoimmune, and hematologic malignant diseases was negative. The presence of chronic urticaria, abdominal pain, hypocomplementemia, and leukocytoclastic vasculitis on skin biopsy confirmed the diagnosis of HUVS. He required hemodialysis for renal failure as well as gastrostomy tube placement for nutritional support secondary to the development of mucosal ulcers, a rare finding in HUVS. He recovered with several months of high-dose steroids and hemodialysis. This case highlights the effectiveness of steroids for initial treatment of HUVS, and the relapsing and remitting nature of the disease. Providers should also be aware of the broad range of presenting symptoms such as mucosal lesions that may require nutritional support. Interestingly, unlike many previously reported cases of HUVS, our patient had not yet developed signs and symptoms of systemic lupus erythematosus, which often overlaps with HUVS.

Lung cancer is the leading cause of cancer-related deaths worldwide, and almost accounts for 20% of these deaths, however, the cure rate is less than 10% [1]. Non-small cell lung cancer (NSCLC) accounts for approximately 85% of all cases of lung cancer [1], but fewer than 15% of individuals diagnosed with NSCLC can survive for more than 5 years, which poses a great threat to the patient’s life and health [2]. Recently, the incidence of lung cancer keeps dynamically growing, but more than 75% of patients at diagnosis has appeared local development or metastasis, missing the best period of surgery. Moreover, despite surgical treatment is the optimal choice for early-stage NSCLC patients, 30%-40% of patients with NSCLC develop tumor recurrence in a short time. Therefore, improving the prognosis of patients with lung cancer and predicting the long-term survival of patients is of particular importance [3]. At present, tumor and node metastasis (TNM) staging system, clinicopathological characteristics, visceral pleural invasion and marginal status are used to predict the disease progression and overall survival of NSCLC patients. There is no index which is stable, effective, reliable and less harmful to assess prognosis, predict recurrence risk and overall survival.

An enquiry into the lack of attention awarded to serotonin antagonism in the treatment of arterial thrombosis revealed that the mode of action of serotonin and its platelet receptor antagonists was an action upon thrombus growth, and not, as with other anti-platelet drugs upon the initiation of thrombosis. This lack of effect could explain why this approach has been considered not to be effective. However under conditions of arterial stenosis in which there is platelet activation by increased shear stress, and during the growth phase of arterial thrombi, serotonin 5HT2A antagonism has been demonstrated to have great potentcy in dispersing thrombotic obstruction to blood flow. This mode of action, the lack of participation of serotonin in haemostasis, and the absence of serotonin in wounds accounts for the proven lack of effect of effect of pure specific 5HT2A antagonists (i.e., not those with other actions) on operative bleeding and skin bleeding times. This lack of effect on haemostasis solves the dosing problem encountered with other anti-thrombotic drugs, with which drug concentration cannot be controlled with single fixed doses, leading to the association between increased anti-thrombotic efficacy and increased bleeding complications. Thus 5HT2A antagonism appears to be the preferred approach, from the point of view of safety and lack of bleeding risk; this consideration applies particularly to thrombosis therapy in the context of traumatic accidents, surgical operations and invasive procedures such as angioplasty.

Background: Pure red cell aplasia is characterized by anemia, reticulocytopenia and diminished bone marrow erythroid precursors. It has multifactorial etiology and consequently several therapeutic interventions. Case: In August 2017, a young patient was diagnosed to have pure red cell aplasia. She was given immunosuppressive therapy for approximately two months but this treatment was stopped due to intolerance. Later on she developed herpes zoster infection that was treated with valacyclovir. Subsequently, it was noted that the patient became blood transfusion independent due to normalization of her hemoglobin and regeneration of the erythroid precursors in the bone marrow. Discussion: Varicella zoster virus behaves differently from other members of the herpes group of viruses such as cytomegalovirus and Epstein-Barr virus. Two retrospective studies, performed in patients with malignant hematological disorders and bone marrow failure, have shown that infection with the virus may cause stimulation of the three cell lines in the bone marrow and superior overall survival. Conclusion: The outcome of the patient presented confirms the findings of the two studies showing long-term beneficial effects of varicella zoster virus infections in immunocompromised individuals.

Introduction: Erdheim-Chester disease (ECD) is a rare and difficult-to-treat non-Langerhans cell histiocytosis characterized by the excessive production and accumulation of histiocytes. This study reports a case of ECD, emphasizing both its diagnosis, assessment and treatment of the pain associated with the disease. Case Report: Six years ago, a 39-year-old male patient presented with generalized pain of moderate intensity in the lower limbs that involved periods of greater intensity associated with ambulation. The diagnosis of histiocytosis associated with panhypopituitarism and adrenal insufficiency was proposed. For a specific diagnosis, a bone lesion biopsy was performed, revealing the presence of histiocytic proliferation that was CD1 negative, S100 protein positive, and CD68 negative. Therefore, the diagnosis of non-Langerhans histiocytosis known as ECD was confirmed. During the two years that followed, the patient presented with severe bone pain, particularly in the lower limbs and cranial vault, and the pain subsided to a certain extent with the use of tramadol and paracetamol. Because of the pain, the patient was unable to walk and became bedridden As the patient remained in severe pain, even after the administration of morphine, the opioid was changed from morphine (60mg/day) to oxycodone (30mg/day) for a convenient dosing schedule; furthermore, the oxycodone dosage was scheduled to increase to 40mg/day that same week. The patient experienced significant pain reduction, requiring rescue analgesia only once or twice a week. Conclusion: To the best of our knowledge, this is the first case report on the characterization and treatment of pain specific to ECD, and we highlight that the patient had a good response to treatment.

Introduction: Fluid management is the cornerstone of treatment for acute pancreatitis (AP), but the proper rate and volume is still controversial. We aim to evaluate the role of aggressive hydration in AP patients. Methods: We retrospectively reviewed and analyzed 279 hospitalized patients of AP. Severity was determined by the Revised Atlanta classification; validated clinical scores were also calculated based on clinical information upon presentation. We extracted amount of fluid received by at 6, 12, 24 and 48 hours after presentation. Aggressive hydration was defined as amount higher than 10 ml/kg bolus followed by infusion at 1.5 ml/kg/h. After direct comparison between aggressive versus non-aggressive hydration groups, propensity-score match was performed to control severity, APACHE II and BISAP score. Post-match comparison as well as a subgroup comparison were conducted. Results: At 24 hours, 125 (44.8%) patients received aggressive hydration averaged at 5.1 L (2-18 L), while 154 (55.2%) patients received non-aggressive hydration averaged at 2.5 L. Post-match comparison showed that aggressive hydration group had longer hospital stay (MAP: 5.3 vs 4.5, p = 0.145, MSAP/SAP: 8.3 vs 4.8 d, p = 0.007), and higher rate of intensive care unit admission (mild: 12.9% vs 4.4%, p = 0.042, moderately severe or severe: 36.8% vs 3.1%, p = 0.001), while showed no difference in rate of mortality or re-admission by 1 year. In patients who presented without organ failure, aggressive hydration did not change the rate of development of organ failure (14.1% vs 12.5%, p = 0.731), but the aggressive hydration group had a trend towards longer hospital stay (5.5 vs 4.6 d, p = 0.083) and higher rate of MICU admission (12.1% vs 4.8%, p = 0.051)

Heterotopic gastric mucosa (HGM) is an islet of gastric mucosa within the esophageal mucosa. These lesions can sit throughout the digestive tract and rarely in the upper third of the esophagus. The pathophysiology of HGM remains poorly understood. Our study aims to estimate the prevalence of HGM, clinical signs, endoscopic, microscopic aspects and different epidemiological factors associated. All patients from a single endoscopy center with HGM of the upper third of the esophagus were included over a 5-month evaluation period. All lesions seen in endoscopy were confirmed by histological analysis. The prevalence was 1.3% with a clear male predominance. 80% of patients were symptomatic and received medical treatment, clinical evolution was good. No case of dysplasia was identified and no complication was observed. Due to insufficient data in the evolutionary literature, the management of HGM remains debated and could resemble that of Barett’s esophagus for monitoring and therapeutic management, particularly in the event of symptoms or dysplasia.

Introduction: Pancreatic pseudocysts (PPs) are mostly delayed complications of acute or chronic pancreatitis and trauma. Pancreatic pseudocysts are usually managed by supportive medical treatment without surgical procedure. All the surgical interventions (percutaneous, endoscopic or surgical approaches) are based on the location, size, symptoms, complications of the pancreatic pseudocyst and medical condition of the patients. Recently, laparoscopic cystogastrostomy has become most appropriate approach especially for retrogastric pancreatic pseudocysts. In this study, we would like to report results of laparoscopic anterior transgastric cystogastrostomy by using linear articulated endo GIA stapler (Covidien medium thick purple) and versa-lifter (versa lifter®, laparoscopic retractor, manufactured by protomedlabs, France) in 14 pancreatic pseudocysts patients. Methods: We retrospectively analyzed data of patients with pancreatic pseudocysts treated by laparoscopic anterior transgastric cystogastrostomy from September 2010 to October 2014. All of the patients were controlled for the recurrence of pancreatic pseudocysts in February 2017. Results: 14 patients with pancreatic pseudocysts were managed by laparoscopic anterior transgastric cysto-gastrostomy. Conversion was performed in only one patient (7%). There were no symptoms and signs of recurrence of pancreatic pseudocyst during on average 43.6 months follow up time. Conclusion: Laparoscopic cystogastrostomy by using articulated linear endo-GIA stapler and versa-lifter is a safe and effective method for management of appropriate retro-gastric pancreatic pseudocysts.

Familial adenomatous polyposis is an autosomal dominant syndrome of variable penetration and constitutes the second frequent inherited syndrome enunciating the emergence of a colorectal carcinoma. The syndrome is accompanied by exemplification of defective adenomatous polyposis coli (APC) gene located upon chromosome 5q21 with a prototypic denomination of colonic adenomatous polyps usually exceeding a > 100. Incriminated individuals develop innumerable colonic and rectal polyps, particularly during early teenage years and are accompanied by an almost 100% possible emergence of colorectal carcinoma within 40 years in untreated subjects [1]. Prophylactic colectomy is advisable to substantially reduce possible occurrence of colorectal carcinoma. Familial adenomatous polyposis is concurrent with associated neoplasms such as gastric or duodenal cancer, hepatoblastoma or desmoid tumour along with a probable emergence of extra-colonic carcinomas [1,2].

Background:While recognition and documentation of true drug allergy is critically important, most physicians acknowledge that its prevalence is likely overestimated, often on the basis of historical, sometimes anecdotal evidence. Correct or not, once applied, drug allergy labels may result in altered, potentially inferior therapy, increased costs and prolonged hospitalisation. Objective:Estimate the point prevalence, accuracy and symptomatology of self-reported drug allergy in a typical, large NHS Acute Trust adult inpatient population. In the subset with penicillin allergy (PA), estimate additional management costs from the use of alternative antibiotics and readmission rates in the previous 5 years. Methods:Data on self-reported drug allergies were extracted from 440 adult inpatient prescription charts over a 4 month period. Where penicillin allergy (PA) was reported, alternative antibiotic regimens were recorded and their additional costs calculated. Hospital electronic records were used to assess readmission rates of PA patients. Results:194/440 inpatients (44.5%) reported at least one drug allergy. Antibiotic allergy was most commonly reported (51%), followed by analgesic (23%) and antiemetic (12%) allergy. PA accounted for 76% of reported antibiotic allergy. The commonest reported symptoms were cutaneous (42%) and gastrointestinal (18%). Where antibiotic therapy was required for patients with PA to manage acute infections, Ciprofloxacin, Clarithromycin, Teicoplanin, Clindamycin and Cefuroxime were the most commonly employed alternatives. Extrapolation of these figures to include the entire Trust inpatient population suggested that the use of alternative antibiotics in PA patients incurred additional annual expenditure of £268,000. Further, 87% of PA patients had been admitted more than once in the preceding 5 years, with 74% requiring further courses of antibiotics during these admissions. Conclusion:Self-reported drug allergy, and in particular PA, is common in hospital inpatient populations and, in addition to the potentially unnecessary hazards to individual patients resulting from the use of alternative antibiotics, results in a considerable additional financial burden to the healthcare system. This problem could be eliminated by the provision of a nationwide and equitable tertiary Allergy service.

Background: Intensive care patients are often in need of sedation to endure being intubated. Light sedation is increasingly common since it has been proved to offer benefits such as faster recovery to patients. Aim: The aim of this study was to describe critical care nurses’ experiences of nursing patients lightly sedated with dexmedetomidine. Research Methodology: Qualitative personal interviews were conducted during 2015 with 10 critical care nurses in Sweden. Interview transcripts were analysed using inductive qualitative thematic analysis. Results: Light sedation of the patient facilitated communication and interaction with him or her, and the relationship between the patient and his or her family members. Dexmedetomidine was described as a fairly new drug, and the critical care nurses stated that they needed more knowledge about it and about sedation scales in order to learn more about the drug’s mechanism of action and its potential side effects on patients. Conclusion: It is important to critical care nurses to learn more about dexmedetomidine and about sedation scales to assess levels of sedation, as light sedation has been shown to benefit the patient as opposed to deep sedation that can increase recovery time.
