The global COVID-19 pandemic is currently underway. A massive worldwide vaccination campaign is still underway, representing the most promising weapon available to stop the pandemic.

However, research continues to investigate the most effective drug treatments to reduce and avoid the most serious complications caused by COVID-19 infection. Recently, new evidence of good therapeutic efficacy against COVID-19 has emerged for the antiviral Remdesivir and the immunomodulatory Baricitinib, also in combination. The first one showed SARS-CoV-2 antireplicative activity, the second one useful to reduce the hyperinflammatory state caused by cytokine storm in the most severe phases of the infection.

In this short communication we describe the molecular pharmacological mechanisms and the latest evidence for the use of these therapeutic agents in the treatment of COVID-19 infection.

Prostate cancer antigen 3 (PCA3) is the most promising diagnostic biomarker for the differential diagnosis of prostate cancer identified to date. As a dominant-negative oncogene, PCA3 negatively regulates the expression of tumor suppressor PRUNE2 (a human homolog of the Drosophila prune gene) gene. Although interaction between PCA3-PRUNE2 was clearly reported, the precise mechanism how PCA3 is upregulated in prostate cancer remained highly elusive. Accordingly, here we aimed demonstrate the role of microRNAs in PCA3 upregulation and interplay between these miRNAs and PCA3-PRUNE2 axis.

We evaluated expression of PCA3, PRUNE2 and miRNAs by quantitative reverse transcription polymerase chain reaction. Overexpression and silencing of miRNAs were achieved by synthetic miRNA mimics and inhibitors, respectively. Colony formation, migration, apoptosis, and cell cycle assays were performed to reveal the effects of miRNA modulation. We identified that PCA3 expression was significantly downregulated in both prostatend therapy.

The efficacy of Bt crystal proteins has been compromised due to their extensive utilization in the field. The second-generation Bt vegetative insecticidal proteins could be the best-suited alternative to combat resistance build-up due to their broad range affinity with midgut receptors of insects.

The codon-optimized synthetic vegetative insecticidal proteins (Vip3Aa) gene under the control of CaMV35S promoter was transformed into a locally developed transgenic cotton variety (CKC-01) expressing cry1Ac and cry2A genes. Transformation efficiency of 1.63% was recorded. The highest Vip3Aa expression (51.98-fold) was found in MS3 transgenic cotton plant. Maximum Vip3Aa protein concentration (4.23µg/mL) was calculated in transgenic cotton plant MS3 through ELISA. The transgenic cotton plant (MS3) showed one copy number on both chromatids in the homozygous form at chromosome 8 at the telophase stage. Almost 99% mortality of H. armigera was recorded in transgenic cotton plants expressing double crystal proteins pyramided with Vip3Aa gene as contrasted to transgenic cotton plant expressing only double crystal protein with 70% mortality.

The results obtained during this study suggest that the combination of Bt cry1Ac, cry2A, and Vip3Aa toxins is the best possible alternative approach to combat chewing insects.

The purpose of the study is to determine the microbiological etiology, epidemiological factors, and clinical profile and treatment outcomes of infective keratitis in Ophthalmology department, Minia University, Egypt.

Prospective, nonrandomized, observational clinical series of cases, including 150 patients with mean age 30 (range 12 to 85years), 90 patients (60%) were males and 60 (40%) were females, clinically diagnosed as infective corneal ulcer, attending the Ophthalmology Department-Faculty of Medicine. Minia University, Minia, Egypt. From December 2018 to December 2020. Detailed history taking and all clinical findings were collected. Corneal scrapings were obtained from patients and subjected to staining and culture for bacterial and fungal pathogens; Bacterial and fungal growth were identified by standard laboratory procedures.

Corneal trauma by a vegetative matter was the commonest risk factor associated with infective keratitis in 92 cases (61.3%). Smear and culture was positive in 83 cases (58.4%) of 142 corneal scrapings obtained, of which 60 cases were fungal (72.3%), 21 cases were bacterial (25.3%) and two cases were mixed bacterial and fungal (2.4%), Aspergillus species was the commonest fungal species isolated in fungal keratitis. One hundred forty-two cases (94.67%) healed completely with scar. Only six cases (4%) required evisceration due to aggressive presentation from the start and keratoplasty was performed for two cases (1.33%).

Fungal keratitis was the commonest type in cases attending to our department. Adequate diagnosis, management and follow-up helped in achieving high successful curative outcomes.

Comparative research on sex and/or gender differences in occupational hazard exposures is necessary for effective work injury and illness prevention strategies. This scoping review summarizes the peer-reviewed literature from 2009 to 2019 on exposure differences to occupational hazards between men and women, across occupations, and within the same occupation.

Fifty-eight studies retrieved from eight databases met our inclusion criteria. Of these, 30 studies were found on physical hazards, 38 studies on psychological/psychosocial hazards, 5 studies on biological hazards, and 17 studies on chemical hazards. The majority of studies reported that men were exposed to noise, vibration, medical radiation, physically demanding work, solar radiation, falls, biomechanical risks, chemical hazards, and blood contamination; while women were exposed to wet work, bullying and discrimination, work stress, and biological agents. Within the same occupations, men were more likely to be exposed to physical hazards, with the . Future research is needed to explain the reasons for sex/gender inequality differences in exposures within the same occupation.Celiac disease (CD) primarily affects the small intestine. Previous studies have identified higher incidences of neuropsychiatric diseases among CD patients compared to non-CD controls. Genome-wide association studies have identified >60 non-human leukocyte antigen (HLA) genes associated with CD, where estimated 15% genes have role in neurological health. We carried out a systematic review and meta-analysis to estimate the potential risk conferred by CD in developing neuropsychiatric diseases. Literature search was performed till June 2019. Incidences of neuropsychiatric diseases were compared among CD and non-CD controls. Funnel plots and Egger's tests were used to evaluate publication bias and estimate study effects. Qualities of the included studies were estimated using Newcastle-Ottawa Scale. Quality of evidence was graded using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. Odds of developing neuropsychiatric diseases among CD were evaluated by computing meta-odds ratio (Manten-Haenszel method) and Z test p-value using random and fixed effect models based on the degree of study heterogeneity. Thirteen non-randomized case-control studies were found eligible. Subjects suffering from CD were found to have significantly more risk to develop depression (p less then 1.00E-05; OR=1.60 [1.37-1.86]), anxiety (p=0.05; OR=1.41 [1.00-1.97]), headache (p less then 0.1.00E-05; OR=3.27 [2.46-4.34]), epilepsy (p less then 1.00E-04; OR=11.90 [3.78-37.43]), panic disorder (p less then 1.00E-04; OR=4.64 [2.22-9.70]), and dysthymia (p=2.00E-03; OR=5.27 [1.83-15.22]). CD is a major predisposing factor in developing array of common neuropsychiatric diseases. Shared biological processes and molecular networks could play a crucial role in disease co-occurrence. Detailed molecular evidences are needed to establish the cause-effect relationship between these diseases.Hepatitis-hydropericardium syndrome (HHS), caused by fowl adenovirus serotype 4 (FAdV-4), has spread on chicken farms worldwide, causing huge economic losses. Currently, the exact mechanism of pathogenesis of FAdV-4 remains unknown. Despite the severe inflammatory damage observed in chickens infected with pathogenic FAdV-4, few studies have focused on the host immune system-virus interactions and cytokine secretion. Host immunity acts as one of the most robust defense mechanisms against infection by pathogens, and cytokines are important in their elimination. However, excessive inflammatory cytokine secretion could contribute to the pathogenesis of FAdV-4. Understanding of the roles of cytokines produced during FAdV-4 infection is important for the study of pathogenicity and for developing strategies to control FAdV-4. Several previous studies have addressed the immune responses to FAdV-4 infection, but there has not been a systematic review of this work. The present review provides a detailed summary of the current findings on cytokine production induced by FAdV-4 infection to accelerate our understanding of FAdV-4 pathogenesis.In clinical work, the magnetic resonance imaging markers of cerebral small vessel disease (CSVD) are frequently observed in moyamoya disease (MMD), but the clinical significance of these markers in MMD remains unclear. This study aimed to fill this gap and systematically investigate its clinical significance. In this retrospective cohort study, we screened all adult patients with MMD hospitalized from January 2016 to January 2020 and collected their baseline clinical and imaging information. Univariate and multivariate logistic regression analyses were then performed to determine which imaging markers were independently associated with MMD characteristics, including cerebrovascular morphology, cerebral hemodynamics, cerebrovascular events, and postoperative collateral formation (PCF). A total of 312 cerebral hemispheres images were collected from the 156 patients with MMD. Using multivariate logistic regression analysis, the following results were generated (1) The presence of lacunes (OR, 2.094; 95% CI, 1.10tential framework for the practical assessment of MMD by magnetic resonance imaging.From ancient times, studies on herbal medicine and pharmacognosy have increased gradually worldwide, due to the increased side effects, adverse drug reactions, and charge lines of modern medicines. Plants are well known for their medicinal effects and nutritional values. They contain bioactive compounds which display a wide spectrum of therapeutic effects. Gaucher's disease (GD) is a rare autosomal recessively inherited metabolic disorder caused due to the defect in Glucosylceramidase beta gene coding for the enzyme acid-β-glucosidase in humans. selleck compound We revealed the profound binding efficiency of five selected bioactive compounds from different plants against the main enzyme acid-β-glucosidase responsible for GD through molecular docking. An in silico approach along with the ADMET profiles of phytocompounds was done using the Schrodinger software. The preventive measure of GD leads to side effects, inaccessible and unaffordable which put forth the emergence of phytocompounds which have fewer toxic effects, and one such compound is β-D-Glucopyranose with the best docking score (-10.
