Dimly illuminated nights alter behavior and negatively affect fat metabolism in adult male zebra finches.

This experiment investigated the effects of an ecologically relevant level of dim light at night (dLAN) on behavior, physiology and fat metabolism associated gene expressions in central and peripheral tissues of adult male zebra finches that were hatched and raised in 12:12 h LD cycle (Ev, day = 150 ± 5 lx; Ev, night = 0 lx) at 22 ± 2 °C temperature. Half of the birds (n = 8) were maintained on LD cycle and temperature, as before (control), to the other half of birds the 12 h dark period was dimly illuminated at ~ 5 lx (dim light at night, dLAN; Ev, day = 150 ± 5 lx; Ev, night =  ~ 5 lx) for 6 weeks. The exposure to dLAN altered the 24 h activity and feeding patterns with enhanced activity and feeding at night.

Comparative Analysis of the Postoperative Analgesic Effects of Caudal Epidural Injection of Ropivacaine Combined With Fentanyl Versus Ropivacaine Alone in Lumbosacral Spine Surgeries: A Randomized Double-Blinded Study.

Introduction: A single injection of local anesthetic as a caudal epidural block provides pain relief for 2-4 hours. This duration can be extended by adding adjuvants such as opioids (morphine, fentanyl, buprenorphine, tramadol), ketamine, α2 agonists (dexmedetomidine, clonidine), and adrenaline. Caudal analgesia also reduces the need for intravenous opioids during and after surgery, which helps avoid the systemic side effects of opioids.

The Relation of Preoperative HbA1c Level With Intraoperative and Postoperative Complications in Type-2 Diabetic Patients: An Observational Study.

Background Perioperative dysglycemia increases morbidity and mortality, particularly among those with diabetes mellitus (DM), and elevated HbA1c levels, reflecting long-term blood glucose, are linked to poor healing and higher infection rates. This study investigates the link between preoperative HbA1c levels and perioperative outcomes in type-2 DM patients. Methodology This prospective observational study was conducted in India between January 2021 and April 2022.

The field of cancer therapy is currently witnessing the emergence of a wide range of innovative approaches.

Whole-body exposure to filtered fraction of diesel exhaust induced localized testicular damage through attenuated functional response of glutathione-s-transferase in adult male Wistar rats.

The possible vulnerability of the male reproductive system to environmental pollutants such as air pollution necessitates a thorough investigation of the underlying mechanisms involved in the dysregulation of male reproductive function. The present study was designed to investigate the influence of the filtered fraction of diesel exhaust (predominantly comprising gases) on male reproductive function in Wistar rat model. Adult male rats were randomly assigned into three groups (n=8/group): Control (unexposed) group (CG-A), the Clean air group in WBE chamber (CAG-A), and Filtered diesel exhaust group in WBE chamber (FDG-A).

A Randomized Study Comparing Ultrasound-Guided Internal Jugular Vein Cannulation Using Two Techniques: Short-Axis Out-of-Plane With Dynamic Needle Tip Positioning Versus Long-Axis In-Plane.

The Hidden Enemy Within: Uncovering the Secrets of HIV Tissues Reservoirs and Current mRNA Vaccine Development.

Human Immunodeficiency Viruses (HIV) continue to pose a significant global health threat despite the availability of antiretroviral therapy (ART). As a retrovirus, HIV persists as a stable, integrated, and replication-competent provirus within a diverse array of long-lived cells for many years, often termed “latent reservoirs” in individuals. Thus, this review aims to furnish a comprehensive overview of diverse tissue reservoirs where HIV persists, elucidating their pathogenesis and advancement in their strategies for clinical management.

Radial Arterial Cannulation by Ultrasound-Guided Dynamic Needle-Tip Positioning Using the Short-Axis Out-of-Plane Approach Versus the Long-Axis In-Plane Approach: A Randomized Controlled Study.

A microdosimetry analysis of reversible electroporation in scattered, overlapping, and cancerous cervical cells.

We present a numerical method for studying reversible electroporation on normal and cancerous cervical cells. This microdosimetry analysis builds on a unique approach for extracting contours of free and overlapping cervical cells in the cluster from the Extended Depth of Field (EDF) images. The algorithm used for extracting the contours is a joint optimization of multiple-level set function along with the Gaussian mixture model and Maximally Stable Extremal Regions.

Study of secondary organic aerosol formation and aging using ambient air in an oxidation flow reactor during high pollution events over Delhi.

Secondary aerosols constitute a significant fraction of atmospheric aerosols, yet our understanding of their formation mechanism and fate is very limited. In this work, the secondary organic aerosol (SOA) formation and aging of ambient air of Delhi are studied using a potential aerosol mass (PAM) reactor, an oxidation flow reactor (OFR), coupled with aerosol chemical speciation monitor (ACSM), proton transfer reaction time of flight mass spectrometer (PTR-ToF-MS), and scanning mobility particle sizer with counter (SMPS + C). The setup mimics atmospheric aging of up to several days with the generation of OH radicals.

Exploring the Relation Between Diabetes and HIV: A Narrative Review.

Diabetes mellitus, more usually abbreviated as DM or just diabetes, is a devastating metabolic disorder that claims many lives every year. Due to various variables, including the aging of the HIV (human immunodeficiency virus)-infected population and the high prevalence of chronic medical conditions among persons living with HIV, the crossroads of DM and HIV infection has become a significant research topic. Although the connection between HIV and diabetes is not simple, many aspects of the virus and its treatment have been connected to the onset of diabetes.
