Assessing Syzygium Aromaticum: From Chemical Profiling to Antioxidant, Antistaphylococcal, and Biocompatibility Attributes.

Staphylococcal infections challenge current treatments due to adverse effects and drug resistance, prompting the exploration of plant-derived compounds for their promising properties. This study aimed to analyze Syzygium aromaticum essential oil (SA-EO), aqueous (AE-SA) and ethyl acetate (EAE-SA) extracts for antioxidant and antistaphylococcal effects against sensitive and resistant clinical isolates. Erythrocytes were used as model cells for biocompatibility.

Rhizospheric miRNAs affect the plant microbiota.

Small ribonucleic acids (RNAs) have been shown to play important roles in cross-kingdom communication, notably in plant-pathogen relationships. Plant micro RNAs (miRNAs)-one class of small RNAs-were even shown to regulate gene expression in the gut microbiota. Plant miRNAs could also affect the rhizosphere microbiota.

Myositis ossificans circumscripta of the thigh: A pediatric case report.

Circumscribed myositis ossificans is a benign process of focal heterotopic ossification of the soft tissues, occurring in young subjects, usually following trauma. We report a case of a 15-year-old patient who suffered a direct trauma to the thigh during a soccer match, and developed a hard mass in the anterior face of the thigh. The patient was diagnosed with myositis ossificans secondary to trauma.

Do nanoplastics impact Pb up-taking by Hordeum vulgare L.?

Most studies on nanoplastics (NPs) focus on aquatic environments, overlooking their combined bioaccumulation with pollutants in terrestrial ecosystems. This study addresses a part of this gap by investigating how polystyrene nanoplastics (PS-NPs) affect the bioaccumulation and translocation of lead (Pb) in Hordeum vulgare L. plants.

Impact of Body Mass Index in the Cardioverter Efficacy of Amiodarone in Persistent Atrial Fibrillation.

Background: Amiodarone is an anti-arrhythmic drug that has extensive tissue distribution and substantial storage in the fat tissue. Different studies have described some implications of body fat composition in its pharmacokinetics and pharmacodynamics. However, no clinical studies have described its implications for clinical efficacy.

Phenanthrene-Induced Cytochrome P450 Genes and Phenanthrene Tolerance Associated with Gene.

Polycyclic aromatic hydrocarbons (PAHs) form an important group of organic pollutants due to their distribution in the environment and their carcinogenic and/or mutagenic effects. In order to identify at the molecular level some of the players in the biodegradation and tolerance response to PAHs in plants, we have phenotyped 32 T-DNA mutant lines corresponding to 16 cytochrome P450 (CYP) genes that showed to be differentially expressed under contrasted stress conditions induced by phenanthrene, a 3-ring PAH. This screening has allowed us to identify (At5g07990) T-DNA mutants as the only ones being sensitive to phenanthrene-induced stress, supporting that CYP75B1 protein is necessary for PAH tolerance.

Tar patties are hotspots of hydrocarbon turnover and nitrogen fixation during a nearshore pollution event in the oligotrophic southeastern Mediterranean Sea.

Weathered oil, that is, tar, forms hotspots of hydrocarbon degradation by complex biota in marine environment. Here, we used marker gene sequencing and metagenomics to characterize the communities of bacteria, archaea and eukaryotes that colonized tar patties and control samples (wood, plastic), collected in the littoral following an offshore spill in the warm, oligotrophic southeastern Mediterranean Sea (SEMS). We show potential aerobic and anaerobic hydrocarbon catabolism niches on tar interior and exterior, linking carbon, sulfur and nitrogen cycles.

Are nanoplastics potentially toxic for plants and rhizobiota? Current knowledge and recommendations.

Soil is now becoming a reservoir of plastics in response to global production, use/disposal patterns and low recovery rates. Their degradation is caused by numerous processes, and this degradation leads to the formation and release of plastic nanoparticles, i.e.

Prevalence of Polyomaviruses and Herpesviruses in Moroccan Breast Cancer.

Breast cancer (BC) is the most frequently diagnosed cancer and the leading cause of cancer death in women worldwide, accounting for 24.5% of total new cancer cases and 15.5% of total cancer deaths.

The Effect of Sub-chronic Linuron Exposure on Thyroid, Liver, and Kidney Function in Male Wistar Rats.

Background: Herbicides are routinely used to control noxious plants. Most of these chemicals may cause toxicity and endocrine disruption in humans and wildlife.

Objective: This study aimed to evaluate the influence of linuron on thyroid hormone levels and some hepatic and renal parameters and organ (thyroid, liver and kidney) structures to assume their toxicity toward experimental animals and to evaluate the endocrine disrupting capacity of this chemical.

Analysis of Small Non-coding RNAs as Signaling Intermediates of Environmentally Integrated Responses to Abiotic Stress.

Research to date on abiotic stress responses in plants has been largely focused on the plant itself, but current knowledge indicates that microorganisms can interact with and help plants during periods of abiotic stress. In our research, we aim to investigate the interkingdom communication between the plant root and the rhizo-microbiota. Our investigation showed that miRNA plays a pivotal role in this interkingdom communication.

Biomarkers Predicting Poor Prognosis in Covid-19 Patients: A Survival Analysis.

Introduction With the spread of the Covid-19 pandemic and its overwhelming impact on health systems in several countries, the importance of identifying predictors of severity is of paramount importance. The objective of this study is to determine the relationship between death and the biological parameters of patients with Covid-19. Materials and methods This is an analytical retrospective cohort study conducted on 326 patients admitted to the Mohammed VI University Hospital in Oujda, Morocco.

Rapid determination of essential oils functional groups using compositional methods and VisNIR spectroscopy.

Essential oils (EOs) are natural products formed by plant volatile compounds. EOs are frequently used in the cosmetic and food industries as well as for domestic purposes, because of their physiochemical, biological and sensory properties. The functional groups (FG), corresponding to various chemical structures present in EOs, are responsible for their biological activities.

Comparative analysis of clinical and biological characteristics of COVID-19 patients: A retrospective cohort study.

Background: Coronavirus disease (COVID-19), caused by a betacoronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has rapidly evolved into a pandemic since it was first reported in December 2019. thus, SARS-CoV-2 has become a major global public health issue.

Objective: The objective of this work is to compare demographics, comorbidities, clinical symptoms, biology and imaging findings between severe and non-severe COVID-19 patients and to identify clinical and biological risk factors and biomarkers for the development of severe COVID-19 as well as predictive thresholds for severity in order to best rationalize management and decrease the morbidity and mortality caused by this condition.

Inhibition of PI3K/C/EBPβ axis in tolerogenic bone marrow-derived dendritic cells of NOD mice promotes Th17 differentiation and diabetes development.

Dendritic cells (DCs) are key regulators of the adaptive immune response. Tolerogenic dendritic cells play a crucial role in inducing and maintaining immune tolerance in autoimmune diseases such as type 1 diabetes in humans as well as in the NOD mouse model. We previously reported that bone marrow-derived DCs (BM.

Pharmacological Cardioversion after Pre-Treatment with Antiarrythmic Drugs Prior to Electrical Cardioversion in Persistent Atrial Fibrillation: Impact on Maintenance of Sinus Rhythm.

Background: Antiarrhythmic drugs (AADs) are frequently initiated in patients with persistent atrial fibrillation (AF) prior to electrical cardioversion (ECV), achieving pharmacological cardioversion (PCV) in some cases. Little is known about the mode of cardioversion and the effect of the type of AAD used in the maintenance of sinus rhythm (SR).

Methods: From three national surveys of patients with persistent AF referred for ECV, we selected those who were pre-treated with AADs (amiodarone or group Ic AADs).
