OCLC Number/Unique Identifier: 9575035815
In this paper, the concentration of As, Cd, Cr, Cu, Pb, and Zn was investigated in soil and Ambrosia artemisiifolia L. sampling from polluted cite near the enterprises for the production and processing of batteries in the city of Dnipro in Ukraine. The obtained results of the study were provided to assess the plant species through bio-monitoring and phytoremediation. Though Ambrosia artemisiifolia L. is a weed that causes serious allergic reactions in humans, this plant species can also have a high bioaccumulative capacity regarding metals. The obtained results highlighted the metals’ significantly higher concentration in roots than in the inflorescence part in Ambrosia artemisiifolia L. Among all studied metals, Zn and Cu had the highest concentration in Ambrosia artemisiifolia L., while lead was characterized by the highest bioavailable content available to plant forms in the soil. The various distribution of As, Cd, Cr, Cu, Pb, and Zn was found in different parts of the plant. According to plant-up-taking indexes studied elements can be ranked in the following descending order: Cu > Zn > Cr > Cd > Pb. Ambrosia artemisiifolia L. could be proposed for phytoremediation in Zn, Cu, Cd, and Cr contaminated soils although this species is resistant to lead soil pollution.

OCLC Number/Unique Identifier: 9575035340
Introduction: Even after surgical resection and adjuvant chemotherapy in pancreatic cancer the 5-year disease-free survival times (DFS), as well as overall survival rates (OS), are still low and median survival times are below 2 years. Here we retrospectively analyzed the outcome of immunotherapy in the additional adjuvant treatment of pancreatic cancer with long antigen exposition dendritic cell therapy (LANEX-DC®) in 28 patients who were treated at our institution. Patients: Data were available from 28 patients. Dendritic cells (LAEX-DC®) were produced according to a recently published protocol.Results: Therapy was well tolerated and no serious side effects were observed. The median disease-free survival times and the median survival times were 16,9 months and 29,4 months respectively. Five-year DFS and OS were 14,3% and 17,9%. Conclusion: We were able to show in a small cohort of patients that additional treatment with dendritic cells (LANEX-DC®) is highly effective and extends the median disease-free survival times as well as the median survival in the adjuvant treatment of pancreatic cancer, whereas the five-year overall survival still remains unsatisfactory.
Efficiency of different methods for calculating the mechanized tunnels face pressure considering an earth pressure balance
Published on: 2nd August, 2022
OCLC Number/Unique Identifier: 9579644518
Different methods for calculating and estimating a safe face pressure were proposed by researchers, which have some advantages and disadvantages. In each of these methods, some related parameters such as soil geotechnical parameters, dimensions of the tunnel, and geological conditions are used. In these methods, using a series of mathematical or empirical functions, the face pressure is calculated. In this study, the face displacements were obtained using the finite difference numerical FLAC3D, the COB (Netherlands Underground Science Center) empirical, and the Leca and Dormieux (1990) analytical methods. The impact of the COB method on different ground stiffnesses is studied and evaluated. The reference case of this research is the Tehran Metro Line 6 tunnel (excavation radius: 4.6 m).
A comprehensive view of metallocycles in Pt(η3–P1X1P2)(Y), derivatives-structural aspects
Published on: 18th August, 2022
This review covers over one hundred Pt(II) complexes of the compositions Pt(η3–P1X1P2)(Y), (X1 = O1L, N1L, C1L, B1L, S1L or Si1L) and (Y = H, F, Cl, Br, I, O2L, N2L, C2L, or P3L). These complexes crystallized in five crystal classes: monoclinic (60 examples), triclinic (36 examples), orthorhombic (13 examples), trigonal (1 example) and tetragonal (1 example). Each heterotridentate organodiphosphine creates two metallocyclic rings with a common X1 atom. There are fourteen types of metallocycles from which the P1C2X1C2P2 is most common. The structural parameters (Pt-L, L-Pt-L) are analyzed and discussed with attention to the distortion of a square-planar geometry about the Pt(II) atoms as well as of trans-influence.
Impact of coronavirus pandemic on safety and time of administration of subcutaneous immunotherapy among pediatric patients
Published on: 2nd September, 2022
OCLC Number/Unique Identifier: 9617323801
Introduction: Allergen immunotherapy is the only targeted therapy that can modify the natural course of allergic diseases. In pediatric patients, SCIT with aeroallergens is an effective treatment and should be considered as a preventive strategy in the treatment of allergic diseases, even though one of the major concerns about it is its safety. The main purposes of this study were to assess the safety of SCIT ultra-rush schedules with polymerized extracts in a pediatric population and to determine the impact of the COVID-19 pandemic on the safety and time of administration of subcutaneous immunotherapy among pediatric patients.Methods: A retrospective medical records review of patients under 18 years of age undergoing SCIT was made and re-scheduling due to restrictions imposed by the COVID-19 pandemic was recorded. Results: A total of 192 pediatric patients were included. Fifty-nine (31%) had local reactions and systemic reactions were not reported. In March 2020, the first case of COVID-19 was diagnosed in Portugal and all non-urgent appointments and procedures were postponed. In our group of pediatric patients, 43 (22%) were referred to primary care, 38 (20%) stopped AIT definitively and 111 (58%) maintained administrations in the hospital. Only 2 (2%) of them had reactions upon reinitiation. Conclusion: In this study, the ultra-rush protocol using polymerized extracts was safe in pediatric patients. Although the effectiveness of AIT may be compromised due to prolonged suspension of the treatment, it is important to note that despite longer interruptions, administrations may continue without compromising safety, maintaining shorter visits and a lower number of injections.

Pandemic as the second stage of the extinction of our civilization
Published on: 4th October, 2022
In the twentieth century, the works of W. Wien, M. Planck and A. Einstein. Lord Rayleigh, Sh. Bose, L. Landau, M. Weinstein, Yu. Chukova and P. Landsberg [1-5] created a new science – quantum thermodynamics, which formulated the law of the efficiency of conversion of electromagnetic radiation into other types of energy for isothermal processes in open thermodynamic systems. This efficiency is of the greatest interest since the whole living world is a huge factory of isothermal processes.
Left ventricular hypertrophy linked with arterial hypertension through centralized aerobic-anaerobic energy balance compensation theory
Published on: 26th October, 2022
We demonstrated intrinsic connections between left ventricular hypertrophy (LVH) and arterial hypertension (AHT) through the recently announced centralized aerobic-anaerobic energy balance compensation (CAAEBC) theory. CAAEBC has already demonstrated achievements in the treatment of AHT, diabetes myelitis (DM), and osteochondrosis. Such demonstration lifts the necessity to check the applicability of this theory to other non-communicable diseases (NCDs) and develop the proper way to model the main idea of CAAEBC.
Flashes of UV-C light are perceived by UVR8, the photoreceptor of UV-B light
Published on: 10th November, 2022
Light is an important regulator of plant morphogenesis and plant-pathogen interactions via specific photoreceptors and signaling pathways. Besides visible light, other electromagnetic radiations may play roles, notably ultraviolet (UV) light. The UV part of the electromagnetic spectrum includes UV-A (315 nm - 400 nm), UV-B (280 nm - 315 nm) and UV-C radiations (200 nm -280 nm). UV-B and UV-C have been reported to increase plant resistance to plant pathogens after the UV perception and signaling stages. The perception of UV-B radiation is achieved by the dimer protein UVR8 (UV RESISTANCE LOCUS 8). Even though the action spectrum of this photoreceptor overlaps in the UV-C domain, it has never been formally demonstrated that UVR8 could also act as a photoreceptor of UV-C light. We provide here original observations showing that UVR8 can indeed perceive UV-C light provided that the latter is in the form of flashes (1s) and not continuous illuminations (the 60s). Our observations also show that the response of UVR8 to flashes of UV-C light is dose-dependent. They could explain why flashes of UV-C light are more effective for stimulating plant defenses than continuous illuminations for the same amount of energy delivered to plants (J/m2). Eventually, our observations support ongoing trials that aim at using UV-C light as an environmental-friendly plant resistance inducer in field conditions.
How to avoid partial implantation of people with cochlear malformation
Published on: 14th November, 2022
Many advances have been made in recent years in the development of hearing and cochlear implants. These use acoustic and electrical stimulation technologies to improve speech intelligibility for the hearing impaired. However, for cochlear prostheses, the results are not very promising and vary from one patient to another. Certain technical and sometimes physiological problems have limited the expected performances of these devices, especially for children and the elderly. These problems include cochlear malformation and ossification of the auditory channels. This led us to reduce the number of electrodes in order to allow quality deep insertion while preserving the low-frequency acoustic bands of the operated patient.

Contamination of a water bottle warmer in neonatal Intensive care unit and Klebsiella Pneumoniae ESBL + outbreak: cases series
Published on: 22nd November, 2022
Infections caused by extended-spectrum β-lactamases (ESBLs)-producing bacteria in particular Klebsiella Pneumoniae (KPE+), are on a constant rise and are a noted cause of outbreaks in neonatal intensive care units (NICUs). In the NICU of Policlinico di Foggia, an outbreak of infections in 2018 brought to the start of a serial check of presence and favorable conditions associated with KPE+ diffusion. The outbreak was controlled by improving basic hygiene measures such as hand washing, the use of disposable gloves and gowns, and removing a potential environmental contamination source such as the water bottle warmer.
Ecology of vital activity as an element of antistress therapy on the example of the organization of the work of a medical center with industrial enterprises under the VMI program
Published on: 29th November, 2022
The pandemic the new Coronavirus infection has brought changes in the health status of a large number of our citizens. The consequence of this has been a higher rate of employees seeking medical care and subsequent sick leave. Crisis phenomena in the economic and social life of society are associated with the consequences of the pandemic, moreover, the stress burden on the population increases with the consequences of the pandemic. All this affects the level of performance. The transferred COVID-19 has increased the number of patients with complaints of pain in joints and muscles, with the phenomena of cardiovascular pathology, as well as in breathing, increased frequency of asthma attacks, etc. That is, complications affected a wide range of diseases [1-4]. All this is the consequence, including neurological pathology, which is closely related to stress. According to surveys of several large industrial enterprises, 31.7% of those seeking medical help report anxiety, sleep problems, and a feeling of fatigue [5]. Exacerbation of chronic diseases was recorded in more than 50% of patients with COVID-19. The figures show that more than 1/3 of the population is chronically unwell, and more often than usual they apply for sick leave, which inevitably leads to a decrease in economic indicators [6-10].
Pain and culture - on cultural communications of suffering
Published on: 29th November, 2022
The impact of culture on the communication of pain becomes visible in a comparative perspective when individuals with two different cultures meet.Regardless of the physiological cause, it is through lived experience, in social life, that it is decided how, where, when and for whom pain is to be communicated. Age and gender, situation and context as well as the type of pain are essential ingredients in communication. The communication is always adapted to expectations from those present, their own experiences of pain and the specific circumstances, the cause of the pain. The impact of culture on the communication of pain becomes visible in a comparative perspective when individuals with two different cultures meet.

Role of CRISPR-Cas9 in agricultural science
Published on: 23rd December, 2022
Clustered regularly interspaced short palindromic repeat (CRISPR), a potent gene-editing tool was found in 2012. CRISPR is a genetic engineering technique that enables genome editing in living creatures and is based on the bacterial CRISPR-Cas9 antiviral defense mechanism. It is simpler, less expensive, and more accurate than previous gene editing techniques. It also has a wide range of valuable uses, including improving crops and treating genetic diseases. Plant science has benefited more from the CRISPR/Cas9 editing technique than medical science. CRISPR/Cas9 has been used in a range of crop-related research and development domains, including disease resistance, plant development, abiotic tolerance, morphological development, secondary metabolism, and fiber creation, as a well-developed cutting-edge biotechnology technique. This paper summarized the role of the CRISPR-CAS9 tool in modern agricultural science.
