Chronic artificial light exposure in daytime and reversed light: Dark cycle inhibit anti-apoptotic cytokines and defect Bcl-2 in peripheral lymphoid tissues during acute systemic inflammatory response to lipopolysaccharide.

Aims: The disturbed light: dark (LD) cycle has been associated with critical complications, including obesity, diabetes and cancer. In the present study, we investigated the chronic effects of artificial light at daytime (AL) and light at night (RAL) after intraperitoneal (i.p.

Exploring the relation between TGF-β pathway activity and response to checkpoint inhibition in patients with metastatic melanoma.

Introduction: Immune checkpoint inhibition (ICI) is highly effective for the treatment of melanoma, but intrinsic resistance is present in a subgroup of patients. TGF-β pathway activity may play a role in this resistance by preventing T-cells from entering the tumor microenvironment, causing immune escape. We investigated the association of TGF-β signal transduction pathway activity with resistance to ICI treatment in advanced melanoma.

Studying decision making in rats using a contextual visual discrimination task: Detection and prevention of alternative behavioral strategies.

Background: The neural bases of decision-making and contextual sensory discriminations have traditionally been studied in primates, highlighting the role of the prefrontal cortex in cognitive control and flexibility. With the advent of molecular tools to manipulate and monitor neuronal activity, these processes have increasingly been studied in rodents. However, rodent tasks typically consist of two-alternative forced choice paradigms that usually feature coarse sensory discriminations and no contextual dependence, limiting prefrontal involvement in task performance.

INFLUENCE OF VITAMIN E ON PANCREATIC ACINAR CELL MORPHOLOGY AND SERUM AMYLASE CONCENTRATIONS IN ALCOHOL-INDUCED PANCREATIC TOXICITY.

Background: Misusing alcohol can cause damage to different tissues in the body, resulting in conditions like alcoholic liver disease, pancreatitis, cardiomyopathy, neurotoxicity, muscle wasting, weakened immune system, hormonal disruptions, birth defects, and bone loss. The objective of this research was to evaluate how alcohol affects the exocrine pancreas histology and the levels of amylase in the blood serum. Additionally, it aimed to explore whether vitamin E provides a safeguard against alcohol-induced harm to the pancreas in rabbits.

Comparative Analysis of Aptamer-Conjugated Chemical and Green Synthesized Gold Nanoparticles for Targeted Therapy in MCF-7 Cancer Cells.

Breast cancer remains a challenging health issue, demanding innovative treatment approaches that maximize efficacy while minimizing damage to healthy cells. Targeted therapy offers a promising strategy tailored to the unique characteristics of breast cancer tumors. Gold nanoparticles have been studied in the context of their therapeutic potential towards cancer treatment showing great success.

TAVI with the ACURATE neo2 in severe bicuspid aortic valve stenosis: the Neo2 BAV Registry.

Background: The ACURATE neo2 is a contemporary transcatheter aortic valve implantation (TAVI) system approved for the treatment of severe aortic stenosis in Europe. The ACURATE neo2 has not been evaluated in bicuspid aortic valve (BAV) stenosis.

Aims: We sought to evaluate the safety and efficacy of ACURATE neo2 in patients with BAV stenosis.

Determining the rate-limiting processes for cell division in Escherichia coli.

A critical cell cycle checkpoint for most bacteria is the onset of constriction when the septal peptidoglycan synthesis starts. According to the current understanding, the arrival of FtsN to midcell triggers this checkpoint in Escherichia coli. Recent structural and in vitro data suggests that recruitment of FtsN to the Z-ring leads to a conformational switch in actin-like FtsA, which links FtsZ protofilaments to the cell membrane and acts as a hub for the late divisome proteins.

Primary antibiotic prophylaxis in biliary atresia did not demonstrate decreased infection rate: Multi-centre retrospective study.

Aim: This retrospective study aimed to assess the efficacy of prophylactic antibiotics in preventing ascending cholangitis following Kasai portoenterostomy (KPE). Data from 72 patients treated across four tertiary centres in Israel from 2008 to 2018 were analysed.

Methods: Clinical and laboratory data were collected from biliary atresia (BA) diagnosis until liver transplantation (LT) or study completion.

Weakly Supervised Classification of Mohs Surgical Sections Using Artificial Intelligence.

Basal cell carcinoma (BCC) is the most frequently diagnosed form of skin cancer, and its incidence continues to rise, particularly among older individuals. This trend puts a significant strain on health care systems, especially in terms of histopathologic diagnostics required for Mohs micrographic surgery (MMS), which is used to treat BCC in sensitive locations to minimize tissue loss. This study aims to address the challenges in BCC detection within MMS whole-slide images by developing and evaluating a deep learning model that bridges weakly supervised learning with interpretable segmentation-based methods through attention maps.

Fueling Recovery: The Therapeutic Role of Ketogenic Diet in Neurological Pathologies.

The ketogenic diet (KD) has gained a lot of attraction in the management of neurological disorders. KD therapies are high-fat, low-carbohydrate diets intended to shift energy consumption and metabolism from carbohydrates to fat in ketogenesis. The oxidative phosphorylation of ketone bodies generates energy packets for body cells, especially the central nervous system, replacing the role of glucose.

Renal satellite units in Pakistan: Challenges, efforts, and recommendations.

This commentary delves into the complexities surrounding chronic kidney disease management in Pakistan, specifically examining the critical role played by renal satellite units in providing accessible dialysis services. Chronic kidney disease in Pakistan accounts for 3.9% of total deaths, warranting a focused exploration of challenges and potential solutions.

The Diagnostic Value of Endobronchial Ultrasound-Guided Fine Needle Aspiration (EBUS-FNA) in Diagnosing FDG-PET-Avid Lymph Nodes in Extrapulmonary Malignancies.

Background and objective The accurate diagnosis of extrapulmonary malignancies with mediastinal lymphadenopathy is crucial for effective patient management. Endobronchial ultrasound-guided fine-needle aspiration (EBUS-FNA) has emerged as a valuable tool in assessing fluorodeoxyglucose (FDG)-positron emission tomography (PET)-avid lymph nodes (LNs). In this study, we aimed to evaluate the diagnostic value of EBUS-FNA in patients with mediastinal lymphadenopathy in extrapulmonary malignancies and compare its efficacy with PET-CT.

Pathogen genomic surveillance status among lower resource settings in Asia.

Asia remains vulnerable to new and emerging infectious diseases. Understanding how to improve next generation sequencing (NGS) use in pathogen surveillance is an urgent priority for regional health security. Here we developed a pathogen genomic surveillance assessment framework to assess capacity in low-resource settings in South and Southeast Asia.
