Dynamic G-Quadruplexes in the Rous Sarcoma Virus Genome: Scaffolds for Protein Interaction and Potential Anti-Viral Targets.

The Rous sarcoma virus (RSV) is an onco-retrovirus that infects avian species such as the chicken (Gallus gallus). RSV is the first oncovirus to be described, and the oncogenic activity of this virus is related to the expression of a tyrosine kinase that induces carcinogenic transformation. Interestingly, we have noted that the RSV genome contains various potential G4-forming sequences.

Host-seeking and exophilic-endophilic activities of Culicoides spp. (Diptera: Ceratopogonidae) with notes on two trapping methods.

Host-seeking behavior of Culicoides species was examined from 2018 to 2019 in West Bengal, India, which elucidated diel activity, feeding success, attack rate, biting rate, and preferential landing of adult Culicoides on the cattle. A comparative assessment was done between the light trap and the aspirator. The host-seeking experiment involved a substantial timeframe of 297 h of catch collections over 27 nights.

Comparative analysis of EGFR mutations in circulating tumor DNA and primary tumor tissues from lung cancer patients using BEAMing PCR.

In this study, we measured human epidermal growth factor receptor (EGFR) mutations in both tissue and circulating tumor DNA (ctDNA) by using beads, emulsions, amplifications and magnetic polymerase chain reaction (BEAMing PCR). Noninvasive mutation detection by assessing circulating tumor DNA (ctDNA) offers many advantages over tumor biopsy. One hundred non-small cell lung cancer (NSCLC) patients were enrolled, and both preoperative plasma samples and formalin-fixed and paraffin-embedded (FFPE) samples were collected for the study.

In Silico-Designed G-Quadruplex Targeting Peptide Attenuates VEGF-A Expression, Preventing Angiogenesis in Cancer Cells.

Vascular endothelial growth factor-A (VEGF-A) is a growth factor and pluripotent cytokine that promotes angiogenesis in cancer cells, transitioning to an angiogenic phenotype. The binding of VEGF-A protein to VEGF receptors (VEGFR-1 and VEGFR-2) initiates a cascade of events that stimulates angiogenesis by facilitating the migration and enhancing the permeability of endothelial cells. The proximal promoter of the VEGF gene encompasses a 36-base pair region (from -85 to -50) that can form a stable G-quadruplex (G4) structure in specific conditions.

Effect of scrotal support application on seroma formation following minimal access surgery for inguinal hernia: A randomised controlled trial.

Background: The incidence of seroma formation is high following laparoscopic surgery for an inguinal hernia. Literature has shown many intraoperative techniques to reduce post-operative seroma formation. The hypothesis was made that scrotal support may reduce seroma formation following laparoscopic or robotic hernia surgery.

Studying the Role of Novel Carbon Nano Tubes as a Therapeutic Agent to Treat Triple Negative Breast Cancer (TNBC) - an and Study.

Triple Negative Breast Cancer (TNBC) is a malignant cancer with a very high mortality rate around the world. African American(AA) women are 28% more likely to die from triple-negative breast cancer (TNBC) than white women with the same diagnosis. AA patients are also more likely to be diagnosed at a later stage of the disease and have the lowest survival rates for any stage of diagnosis; There are very few existing anti TNBC drugs with therapeutic efficacy hence newer anti TNBC drug design and investigation is needed.

Exploring heterogeneity in mild cognitive impairment.

Background: Mild cognitive impairment (MCI) is a heterogeneous diagnostic entity, without a clear prognosis, often accompanied by psychiatric symptomatology and physical frailty.

Objective: Understanding the heterogeneity within MCI is a critical step in improving the early detection of cognitive decline and developing effective interventions.

Methods: Cross-sectional multivariate latent mixture analyses of data from patients evaluated between 2015 and 2019, who were routinely entered into a multidisciplinary database for research purposes.

This paper presents strategic consensus from the Transdisciplinary Research, Advocacy, and Implementation Network for Trauma in India (TRAIN Trauma India) symposium, advocating for enhanced, system-level trauma care to address this challenge. Methods Five working groups conducted separate literature reviews on pre-hospital trauma care, in-hospital trauma resuscitation and training, trauma systems, trauma registries, and India's Towards Improving Trauma Care Outcomes (TITCO) registry.

Unanticipated evolution of cardio-respiratory interactions with cognitive load during a Go-NoGo shooting task in virtual reality.

The cardiovascular system interacts continuously with the respiratory system to maintain the vital balance of oxygen and carbon dioxide in our body. The interplay between the sympathetic and parasympathetic branches of the autonomic nervous system regulates the aforesaid involuntary functions. This study analyzes the dynamics of the cardio-respiratory (CR) interactions using RR Intervals (RRI), Systolic Blood Pressure (SBP), and Respiration signals after first-order differencing to make them stationary.

Application of bio-layer interferometry for the analysis of ribosome-protein interactions.

The ribosome, a ribonucleoprotein complex, performs the function of protein translation. While ribosomal RNA catalyzes polypeptide formation, several proteins assist the ribosome throughout the translation process. Studying the biochemical and kinetic properties of these proteins interacting with the ribosome is vital for elucidating their roles.

The case describes a rare instance of Quain hernia, a specific type of internal hernia where the bowel protrudes through a defect in the broad ligament. Broad ligament defects can either be congenital or acquired. Quain hernias are uncommon and difficult to diagnose due to nonspecific symptoms.

Menstrual hygiene behaviour among the tribal married women aged 15 to 49 years: A cross-sectional study in a community development block of Paschim Bardhaman District, West Bengal.

Background: Menstrual hygiene management is integrally associated with reproductive health of women. Menstrual health and hygiene needs, particularly of tribal women still remain unmet for many reasons. Inappropriate menstrual behaviour leads to adverse health consequences.

Clinical Characteristics of Migraine and Their Association With the Retinal Nerve Fiber Layer Thickness.

Background: Migraine is characterized by recurrent episodes of unilateral, pulsating headaches. At the cerebral and ocular levels, it is recognized that the vascular narrowing and loss of blood flow are transient; however, the chronic nature of migraine may result in long-term functional and structural changes in these structures. It could result in axonal loss and an alteration in the thickness of the retinal nerve fiber layers (RNFL).

Integration of Sensor-Based and Self-Reported Metrics in a Sleep Diary: A Pilot Exploration.

Objectives: Discrepancies between sleep diaries and sensor-based sleep parameters are widely recognized. This study examined the effect of showing sensor-based sleep parameters while completing a daily diary. The provision of sensor-based data was expected to reduce variance but not change the mean of self-reported sleep parameters, which would in turn align better with sensor-based data compared to a control diary.

Molecular and physiological changes in the SpaceX Inspiration4 civilian crew.

Human spaceflight has historically been managed by government agencies, such as in the NASA Twins Study, but new commercial spaceflight opportunities have opened spaceflight to a broader population. In 2021, the SpaceX Inspiration4 mission launched the first all-civilian crew to low Earth orbit, which included the youngest American astronaut (aged 29), new in-flight experimental technologies (handheld ultrasound imaging, smartwatch wearables and immune profiling), ocular alignment measurements and new protocols for in-depth, multi-omic molecular and cellular profiling. Here we report the primary findings from the 3-day spaceflight mission, which induced a broad range of physiological and stress responses, neurovestibular changes indexed by ocular misalignment, and altered neurocognitive functioning, some of which match those of long-term spaceflight, but almost all of which did not differ from baseline (pre-flight) after return to Earth.

Effects of transcutaneous electrical nerve stimulation on recovery of gastrointestinal motility after laparotomy: A randomized controlled trial.

Introduction: Postoperative Ileus (POI) negatively impacts patient outcomes and increases healthcare costs. Transcutaneous electrical nerve stimulation (TENS) has been found to improve gastrointestinal (GI) motility following abdominal surgery.
