Assessment of the microbial load of the operating environment during daily pre-, intra-, and post-operative procedures in a surgical department of a military emergency hospital in Bucharest showed the bacterial contamination of intra-operative air by increasing the number of bacteria above the allowed maximum level and the detection of a strain of Escherichia coli (E. coli).

The introduction of a new class of drugs known as direct acting antiviral (DAA) agents represents a revolution in the treatment of hepatitis C virus (HCV) in the general population, as these regimens are associated with higher sustained virological response (SVR) rates and fewer side effects. However, for patients with advanced chronic kidney disease suffering from HVC infection, treatment options including DAA remain limited. The aim of this study is to report our experience on Sofosbuvir (SOF) based regimen in the treatment of HCV in hemodialysis patients.In this observational study, we included all patients with chronic HCV infection on hemodialysis who were treated with SOF in our Hospital between April 2016 and March 2018. All patients were treated with a combination of 400 mg of SOF three times a week after hemodialysis and of 60 mg of Daclatasvir daily for a total of 12 to 24 weeks.A total of 20 hemodialysis patients were included in this study. 12 were females and the mean age was 52.1 ± 15.5 years. 11 patients were infected with HCV genotypes 1b. All patients achieved SVR. Clinical and biological tolerance was very good for all patients and none of them had to discontinue treatment because of side effects or developed hepatobiliary and cardiac toxicity. Two patients reported fatigue and another patient reported headaches. However, these symptoms were spontaneously resolved after the end of the treatment.In Morocco, despite the absence of new DAA combination treatment regimens which are not renally eliminated, our study concludes that SOF based treatment without Ribavirin or Peginterferon was effective and safe with minimal side effects. However, larger studies are still needed in order to validate these results.

Flow cytometry (FCM) is a unique technique that allows rapid quantitative measurement of multiple parameters on a large number of cells at the individual level. FCM is based on immunolabelling with fluorochrome-conjugated antibodies, leading to high sensitivity and precision while time effective sample preparation. FCM can be performed on tissue following enzymatic or mechanical dissociation. The expression of epithelial antigens and cytokeratin isoforms help in distinguishing tumor cells from adjacent epithelial cells and from tumor infiltrating leukocytes. Tumor phenotypes can be characterized on expression intensity, aberrancies and presence of tumor-associated antigens as well as their cell proliferation rate and eventual heteroploidy. FCM can measure quantitative expression of hormone or growth factor receptors, immunoregulatory proteins to guide adjuvant therapy. Expression of adhesion molecules tells on tumor’s capacity for tissue invasion and metastasis seeding. Tumor heterogeneity can be explored quantitatively and rare, potentially emerging, clones with poor prognosis can be detected. FCM is easily applicable on fine needle aspiration and in any tumor related biological fluids. FCM can also be used to detect circulating tumor cells (CTC) to assess metastatic potential at diagnosis or during treatment. Detecting CTC could allow early detection of tumors before they are clinically expressed although some difficulties still need to be solved. It thus appears that FCM should be in the pathologist tool box to improve cancer diagnosis, classification and prognosis evaluation as well as in orientating personalized adjuvant therapy and immunotherapy. More developments are still required to better known tumor phenotypes and their potential invasiveness

To investigate the associated an inappropriate development of the 9-month-old-baby with the Matched Case-Control Study on five categories and three factors including predisposing, contributing, and complementary through the babies’ malfunction development with the Analysis Research Method was analyzed. The babies’ developing crisis was enhanced as the guidelines for promoting healthy babies’ development via the DSPM in the future of Thailand. Creative the Interview Factor Questionnaire analyzed the 130-child caregivers’ parenting matching 65-pairs-case-control group into 5 parts: the Predisposing Factor Questionnaire, the Positive Interview Form; the Baby-Self-Efficacy Form; the Inappropriate Contributing Interview Form; the Inappropriate Development Interview Form for assessing the motor skills, self-efficacy, predisposing, contributing, and complementary factors of the 9-month-old-baby, respectively. Highest, Middle, and Lowest means levels are indicated. The child caregivers’ are presenting responses, overall on the Predisposing Factor Questionnaire on five categories’ motor skills, and the Inappropriate Development Interview Form showed off at the Middle Levels. The Positive Interview Form, the Baby-Self-Efficacy Form, and the Inappropriate Contributing Interview Form comprised at the Highest Levels for the predisposing, self-efficacy, and contributing factors for developing the 9-month-old-baby, respectively. To help professionals assess the factors affecting a child’s development into environmental factors, biological factors, interpersonal relationships, and early environments and experiences that identified in contributing to growth, brain, emotional, social developments at early childhood are the GM, FM, RL, EL, and PS motor skills practices with the DSPM for Thai’s children are also more likely to have health problems all child ages with the knowledge and skills.

Development of genetic profiles from the biological mixtures has remained challenging, although modern-day technologies may help forensic scientists to attain a reliable genetic profile in the identification of the accused. In the case of rape, vaginal swab exhibits usually contain epithelial cells of victims and sperm cells of accused, such samples are more challenging when there is more than one contributor. In such cases, separation of distinct cells from a mixture that includes blood cells, epithelial cells and sperm cells for their single genetic profile is important. In the last ten decades several new techniques were developed and invented for the separation of single cell from the biological mixture that includes differential lysis, laser micro-dissection, cell sorting (FACS), sieve-based filtration, (vi) micro-fluidic devices or immunomagnetic beads cell separation of fresh samples, and the magnetic activated cell sorting (MACS). Out of them, some techniques have been commonly applied for cell separation in forensic biology. Each technique has its own limitation. Some recent studies showed, magnetic activated cell sorting (MACS), laser capture microdissection (LCM), DEPArray technology and fluorescence activated cell sorting (FACS) has proved to be effective in separation of single cell from cell mixtures. Therefore, in this review we have evaluated these four alternative methods and their potential application in the modern-day over the others for the separation of a single cell from the mixture. In this review we also discuss the advantage of these methods and their modern–day applicability and acceptance in the forensic world.

One of the major challenges for vaccine producing companies is having favourable conditions for efficient expression system for living organisms in order to produce biologicals. Several companies across the globe looking for several alternative sources for better yield through efficient expression based system.

Presently Packaging plays a significant role for Biosimilar product. The process of selecting materials and the type of packaging also offers an opportunity for the Packaging scientist to look for new biological delivery choices. Most injectable protein products were supplied in some sort of glass vial, prefilled syringe, and cartridge. Those product having high Ph content there is a chance of “delamination “from inner surface of glass vial. With protein-based drugs, the biggest issue is the effect of packaging derivatives on the protein’s three-dimensional and surface structure. These are any effects that relate to denaturation or aggregation of the protein due to oxidation or interactions from contaminants or impurities in the preparation. The potential for these effects needs to be carefully considered in choosing the container and the container closure system to avoid putting patients in jeopardy.

Background: The survival of people living with HIV (PLWHIVs) is increased and Health systems will have to deal with the early-aging-associated medical conditions.Objective: The objective of this study is to compare the clinical and biological profiles of PLWHIVs aged 50 and over and those aged less than 50 years.Material and methods: This study conducted at Kinshasa University Teaching Hospital (KUTH) covers 6 years. The clinical and biological characteristics of PLWHIVs aged 50 and over were compared with those under 50. Statistical analysis used the means ± SD, the calculation of frequencies, Student’s t-test and Chi-square.Results: PLWHIVs aged 50 or over represented 35.1%. Their average age was 58.0 ± 4.8 years. Women predominate among those under 50 and men among those 50 and over. Married people were more numerous (54% among those under 50). There were more unemployed (50% of PLHIV under 50). Patients 50 years and older were significantly classified as WHO stage 4 with a high frequency of history of tuberculosis, genital herpes, high blood pressure, smoking, vomiting, hepatomegaly, moderate elevation of diastolic blood pressure (DBP) and sytolic blood pressure (SBP), tuberculosis and anemia.Those under 50 had a significantly increased frequency of shingles, hepatitis B-hepatitis C, headaches and more survivals. The mean of Hb, HDL-C, and CD4s+ were significantly lower in patients 50 years and older, and urea, LDL-c, and ALAT levels were significantly higher. Conclusion: The average age was higher from 50 years old. These PLWHIVs were more frequently in WHO stage 4 with more common TB and anemia. Their Hb, HDL-C, and CD4s+ levels were lower while their urea, LDL-C and ALAT levels were significantly elevated.

Background: Chronic kidney disease is a worldwide public health issue which is associated with an increased risk of end-stage renal failure and cardiovascular disease. Systemic inflammation exists during chronic renal failure. Recent researches have highlighted the pivotal role of inflammation between renal and cardiovascular disease. The aim of our study is to determine the inflammatory profile of the patient suffering from chronic kidney disease and the influence of hemodialysis on this profile.Methods: We carried out a cross sectional study on 93 patients in the Nephrology Department at Hedi Chaker University Hospital, Sfax, South of Tunisia. Among those patients, 72 patients underwent hemodialysis and 21 patients had chronic kidney disease at stage 3. Clinical data and antecedents were collected. Biological samples were taken after informing the patients and taking their consent. Biological data consisted in lipid profile, albumin rate, hemoglobin rate, uric acid concentration and the usual markers of inflammation noting sedimentation rate, C - reactive protein and orosomucoid.Results: Hemodialysis group of the 72 patients had mean hemodialysis vintage of 54.6 ± 43 months. The inflammatory profile was worse in hemodialysis patients compared to chronic kidney disease patients. Both sedimentation rate, C - reactive protein and orosomucoid were higher in hemodialysis group than in chronic kidney disease group with 71 ± 35.3 mm vs. 42.1 ± 15.5 mm (p < 0.05); 14.6 ± 28.7 mg/l vs. 6.7 ± 8 mg/l (p = 0.02); 1.3 ± 0.7g/l vs. 0.9 ± 0.4 g/l (p = 0.01), respectively.Conclusion: Inflammation increases in dialysis patient. It deserves the nephrologist’s consideration in order to minimize its harmful effects. The monitoring of inflammation markers must be integrated into the nephrologist’s medical practice.

The article shows that the current level of physiology does not disclose the biological mechanisms of the organism’s transition from one range to adapt to a higher one with an increase in the regular forces of the stimulus above sub-extreme. A new trend in the physiology of adaptation - proqredient adaptation, explains the mechanism of increasing the tolerance of the organism, with dependence on psychoactive substances (PAS). Scientific has reasonably shown that depending on the organism from PAS - not the disease, and the states like proqredient adaptation.

Deoxyribonucleic acid (DNA) extraction has considerably evolved since it was initially performed back in 1869. It is the first step required for many of the available downstream applications used in the field of molecular biology and forensic science. Blood samples is one of the main body fluid used to obtain DNA. This experiment used other body fluids such as saliva, sweat tears and mucus. There are many different protocols available to perform nucleic acid extraction on such samples. These methods vary from very basic manual protocols to more sophisticated methods included in automated DNA extraction protocols. This experiment used extraction kit (Zymo research). The DNA result from isolated saliva samples on the facemask range from 133.7, 213.6, 599.1 and 209.1 mg/ml. theoretically; such DNA is of much quantity and quality and can be used for forensic investigation when recovered from a crime scene. The DNA from isolated tears samples on the face mask ranges from 707.7, 202.5, 99.2, and 62.6 mg/ml. Theoretically, such DNA is of much quantity and quality and can be used for forensic investigation when recovered from a crime scene. The DNA from isolated tears samples on the face mask ranges from 615.3, 66.2, 78.5, and 68.2 mg/ml. theoretically, such DNA is of much quantity and quality and can be used for forensic investigation when recovered from a crime scene. Extracted DNA from saliva and sweat produced visible bands on agarose gel, mucous stain produce obscure band on agarose gel and the tears stain produce invisible bands. DNA from sweat satin, saliva stain, mucus stain and tears stain in face mask can be used as alternative for forensic investigation.

DNA identification is very important in cases of high decomposition of dead bodies, in which the bodies cannot be identified by physical means.To compare the results of DNA typing, it is necessary to have related subjects with which to perform comparative analyses. Such tests are normally performed by comparing DNA profiles from people known to be immediate family members of the presumptive victim, such as parents or children because they share half of their genetic material with the unidentified.We report on how DNA analysis was used to solve a case of mixed-up bodies at a local mortuary in Ghana, West Africa. Two families and three buried human remains were in contention in this case. The first body (E9) was buried three months before exhumation. The second body (E11) was buried two and a half months before exhumation whiles the third body (E10) was buried a month before exhumation. Exhibit E5 was taken from an alleged child of the deceased, E11. Toenails of the exhumed bodies were sampled by a pathologist and used for DNA extractions using the QIAamp DNA Investigator Kit. Profiles from relatives were generated for comparison purposes. All samples gave a quality amount of genomic DNA after quantification. DNA was amplified with a GlobalFiler PCR amplification kit. Profiles from relatives were generated for comparison purposes.The human remains (exhibit E11) cannot be excluded as the biological father of the child (exhibit E5) because they share common alleles at all 23 genetic loci. The applicable combined paternity index was 17218125604.492 assuming a prior probability of 0.5. The probability of paternity is 99.99999999%. Based on this relationship testing, one of the bodies was successfully identified and handed over to the family for re-burial.

The objective of this study was to obtain a fast, accurate and reliable method of species identification of unknown biological samples for forensic applications, especially in illegal trade of animals as well as meat fraud. Meat fraud and adulteration not only affects the market but also increases the risk of religious and ethnic conflicts around the world [1]. In this study, species-specific and gender differentiating Real time PCR technique was employed to analyse 15 meat samples collected from a suspected site. Out of 15 samples collected from suspected site, 54% and 13% samples were of Cow and buffalo origin respectively. All 54% cow samples were of male while one each of buffalo were of male and female origin. Two samples were inconclusive. These findings indicated that species and gender-specific PCR is very sensitive and can be used for forensic species identification and the detection of meat fraud and adulteration.

Specific receptors for atrial natriuretic peptide (ANP) located in intra-ovarian tissues are suggested to be involved in ovarian functions such as oocyte maturation and follicle development. However, the characteristics and modulation of its receptor in relation to ovarian folliculogenesis are not well defined. This study examined the properties of ANP receptors in the ovary using quantitative receptor autoradiography. In the pig ovary, the highest binding sites for 125I-ANP(1-28) were localized in the granulosa cell layer of the follicles as well as cumulus oophorous. The binding sites for 125I-ANP(1-28) on theca layer of the ovarian follicles were mainly localized in the external layer, but none was observed in the internal layer. Specific binding of 125I-ANP(1-28) was not found clearly in atretic follicles. In the corpus luteum, the binding site was not observed. Analysis of the competitive inhibition of the binding of 125I-ANP(1-28) to the granulosa and theca externa layers in various preovulatory follicles by increasing concentrations of unlabeled ANP(1-28)was consistent with a single high affinity for 125I-ANP(1-28). The maximal binding capacities of 125I-ANP(1-28) in granulosa layer were significantly increased in proportion to the development of ovarian follicles. However, no significant difference of binding capacities of 125I-ANP(1-28) was observed in theca externa layer. The binding affinities of 125I-ANP(1-28) in granulosa and theca externa layers were not different from each other. Especially, the correlation between specific binding of 125I-ANP(1-28) and follicle diameter. A significant correlation was revealed between specific binding of 125I-ANP(1-28) and follicle diameter (R = 0.88, p < 0.0001) in granulosa layer, however, less relationship was detected in theca externa layer (R = 0.50, p < 0.0001). Therefore, these results indicate that the biological ANP receptors exist in granulosa and the theca externa layers of the pig ovary, and suggest that the ANP receptors in granulosa layer may be related to the regulatory function of the ovarian follicullogenesis including oocyte maturation.

Introduction: Oxidative stress is a phenomenon induced by an imbalance between production and the biological system's ability to readily detoxify oxygen reactive species (ROS) in cells. It has been shown that grape juice can reduce oxidative stress due to the presence of polyphenols. The aim of this study was to evaluate the effect of fresh red grape juice and grape fermentative product on oxidative stress in human erythrocytes.Methods: 5 ml of blood from 125 healthy individuals as control group collected in EDTA containing tubes. To perform biochemical assays, erythrocytes were incubated at 37 ºC for different times including 4, 24, 48, and 72 hours in the presence or absence of grape juice and grape red wine in amounts of 5 ml. Results: Grape juice and grape red wine reduced lipid peroxidation and increase of thiol groups, and total antioxidant capacity after 24 hours of treatment (p < 0.05). Also, the activity of catalase enzyme was increased 4 and 24 hours after treatment with red wine and grape juice, respectively. Conclusion: Grape juice and grape fermentative product may improve the antioxidant power of erythrocytes. This may lead to reducing the risk of free-radical damage and chronic diseases. However, more research with a higher number of samples is necessary to confirm the antioxidant effect of grape juice and red wine on human erythrocytes.

SARS-CoV-2 revisits a children’s fairy tale, the Emperor’s New Clothes. The swindler- salesmen are Biden, Fauci, et al. The magical clothes are their deliberate “pandemic of fear,” and the duped emperor is the American public.Extensive evidence is presented here of a great scam. The data details the true and low health risks of SARS-CoV-2; viral biology of natural immunity and the immune response from experimental mRNA gene therapy; side effects of the “jab;” and the draconian consequences of federal mandates. Differences between official pronouncements and scientific data are highlighted.The goal of the SARS-CoV-2 Big Con or scam is the nullification of the U.S. Bill of Rights in order to restore tyranny over the American public. We the People can fight for freedom with ballots and dollars.

A literature-based review was made to assess available information on bovine hemoparasites related to their epidemiology, distribution, and economic importance in Ethiopia. Babesiosis, anaplasmosis, cowdriosis, theileriosis, and trypanosomosis are the major hemo-parasitic disease of bovine in Ethiopia. Their adverse effects on the health of the animals can decrease production and productivity. Hemoparasites generally cause fever, anemia, jaundice, anorexia, weight loss, milk drop, malaise, swelling of lymph nodes, dyspnoea, diarrhea, nervous disorders, and death by affecting blood vessels and/or lymphatic system of the animal. Reports from different parts of the country displayed there is a high distribution of bovine hemoparastic disease throughout the country. Anaplasmosis, Babesiosis (redwater), Ehlichiosis (Heartwater), Theileriosis, and Trypanosomosis are the major hemoparasitic diseases with heavy economic losses. Their mode of transmission was by arthropod vectors ticks and flies. Applying effective vector control and using vaccines drugs are the two most important control methods for hemoparasites diseases. Also having knowledge of parasite life cycles, their biological vector, and the immune response of bovines to vectors and parasites were also used in the successful application of control strategies. Creating awareness of the mode of transmission, method of control, and prevention of hemoparastic disease of bovine to livestock owners were warranted to decrease the effect of the disease.

Plants have a high concentration of biologically active molecules. Aloe plants tend to store water and important chemical constituents in their swollen and succulent leaves due to their ability to survive in hot and dry conditions, which makes them a unique source of phytochemicals. The Aloe leaf contains more than 200 nutritional substances, including vitamins, minerals, amino acids, and active enzymes. These constituents are analyzed as phytochemical screening (qualitative analysis) or proximate and mineral content analyses (quantitative analysis). Aloe is used as a food product and beverage ingredient. Functional and nutraceutical foods, edible coatings/films, Aloe species as cooked vegetables, and raw eating of Aloe species are how the Aloe plant is considered in food applications. The researchers reported edible Aloes for several species. However, it is not mean that all species of Aloe are edible. It is not only the leaves of Aloe that have nutritional values also other parts of the plant do. The study evaluated the nutritional value of Aloe flowers and their possible use as edible flowers. Aloe species are increasingly being incorporated into different health drinks, foods, and beverages due to the beneficial biological activities of the phytochemicals.

Diseases - diabetes mellitus (especially type 1) and autoimmune diseases are incurable diseases. In type 1 diabetes, the beta cells of the tail of the pancreas die. It is in the beta cells of the tail of the pancreas that insulin is located, a hormone that maintains normal blood sugar levels in patients with type 1 diabetes. Until now, no methods have been known to restore dead pancreatic beta cells. Methods for restoring the lymphoid system in patients with autoimmune diseases were not known. With these diseases, the normal properties of the lymphoid system are lost. This review aims to present materials on the effective treatment (cure) of these diseases. For the treatment, the resonance therapy method was used, which has been known for at least 25 years and which has been modified in our work since 2016. The essence of our modification was that the author began to use 1. Not only low (previously known) but also high potencies of resonant drugs. 2. We have created a direction in resonance therapy, which is called “resonance of creation.” So far, only the direction is known as “resonance of destruction” is known, with the help of which oncological tissues, infectious processes, cysts, stones, etc. are treated - destroyed. With the help of the resonance of creation, various biological structures that have undergone degeneration and death are restored - the myelin sheath of the nerves in multiple sclerosis, nerve cells in Parkinson’s disease and Alzheimer’s disease, etc. With the help of the resonance of creation, the beta cells of the tail of the pancreas are restored in type 1 diabetes and restoration of the lymphoid system in autoimmune diseases. So, in patients with autoimmune diseases, organ preparations were tested: “lymph nodes”, “lymphocytes”. It turned out that in all patients with various autoimmune diseases, lymph nodes, and lymphocytes were tested as being in a degenerative state. There was not a single patient whose lymph nodes and lymphocytes were tested as normal. The task was to normalize the functional state of the lymph nodes and lymphocytes in our patients and thereby take an important step towards curing their autoimmune disease. To this end, it was necessary to increase the potency of the lymph nodes and lymphocytes in the same way as we did it in relation to the beta cells of the pancreas in patients with diabetes mellitus, in relation to the substantia nigra of the midbrain in patients with Parkinson’s disease and in relation to the myelin sheath. Nerves in multiple sclerosis. After testing organ preparations: “lymph nodes”, and “lymphocytes” in patients with autoimmune diseases, the potency was selected, which led to the fact that lymph nodes and lymphocytes were no longer tested as degenerated formations. It was this potency of lymph nodes and lymphocytes that was the basis for the treatment of patients. Thus, as a result of the treatment of diabetes mellitus (especially type 1) and autoimmune diseases by resonance therapy, these diseases become curable.

Genome-wide association studies (GWAS) have uncovered thousands of single nucleotide polymorphism (SNP) loci that are associated with complex traits. However, the majority of GWAS discoveries are located in non-coding regions and the biological mechanisms behind these associations are not well understood. Transcriptome-wide association studies (TWAS) have gained popularity in recent years by generating biological interpretable discoveries and facilitating the identification of novel associations that have been missed by GWAS. TWAS has identified more than hundreds of susceptibility genes for many complex diseases and traits, including cancers. Here, in this review, we first summarize TWAS methods, then discuss the opportunities for cancer studies and finally review current challenges and future directions for this method.
