Automated denoising software for calcium imaging signals using deep learning.

Dynamic Ca signaling is crucial for cell survival and death, and Ca imaging approaches are commonly used to study and measure cellular Ca patterns within cells. However, the presence of image noise from instrumentation and experimentation protocols can impede the accurate extraction of Ca signals. Removing noise from Ca Spatio-Temporal Maps (STMaps) is essential for precisely analyzing Ca datasets.

A Comprehensive Analysis of Wait Times in Ambulatory Obstetrics and Gynecology Clinic at a Tertiary Care Hospital in Pakistan.

Objective Wait times are an important determinant of patient satisfaction measured objectively and associated significantly with it. It is a measure of time taken from the arrival of patients to the registration desk of a facility to the time they access service. This study focuses on current patient pathways at the Obstetrics and Gynecology Outpatient (OBGYN) Ambulatory Clinic at Shalamar Hospital and assesses wait times by stratifying it at each step of the pathway.

Setting the Stage: Feasibility and Baseline Characteristics in the PARTIQoL Trial Comparing Proton Therapy Versus Intensity Modulated Radiation Therapy for Localized Prostate Cancer.

Purpose: Men with localized prostate cancer may receive either photon-based intensity modulated radiation therapy (IMRT) or proton beam therapy (PBT). The PARTIQoL trial (NCT01617161) demonstrates the feasibility of performing a large, multicenter phase 3 randomized trial comparing IMRT with PBT for localized prostate cancer. Here, we report baseline features of patients enrolled on this trial and present strategies to improve feasibility of other similar trials.

A comparative study on the effects of doxycycline, nalidixic acid and meropenem on Escherichia coli in inducing urinary tract infections.

Urinary tract infections are widely recognized as prevalent bacterial infections frequently encountered in both hospital and community settings. The most common gram-negative bacterial pathogen in humans, extra-intestinal pathogenic Escherichia coli, causes these diseases. A retrospective cross-sectional study in Karachi, Pakistan examined Escherichia coli's susceptibility to doxycycline, nalidixic acid and meropenem.

Synergistic anti-tumorigenic effect of diosmetin in combination with 5-fluorouracil on human colon cancer xenografts in nude mice.

5-Fluorouracil (5-FU) is frequently used to treat colorectal cancer (CRC), but its clinical application is limited by its toxicity. Natural compounds have been combined with chemotherapeutic drugs to reduce chemotherapy-related toxicity. Diosmetin, a natural flavonoid, has demonstrated anticancer effects against CRC.

New Glycotoxin Inhibitor from Mitigates Symptoms of Insulin Resistance and Diabetes by Suppressing AGE-RAGE Axis in Skeletal Muscle.

The current study intended to investigate the role of new natural compounds derived from the plant in mitigating symptoms of diabetes and insulin resistance in the diabetic mice model. Anti-advanced glycation activity, insulin, and adiponectin were quantified by enzyme-linked immunosorbent assay (ELISA). Glucose uptake was performed using enzymatic fluorescence assay, and glycogen synthesis was measured using PAS staining.

Disparities in Penile Cancer Incidence, Mortality, and Place of Death Trends From 1999 to 2020.

Introduction: Penile cancer is rare in the United States (US); however, disparities have been found in the incidence, treatment, and outcomes of penile cancer. There is a need for evaluation of recent trends in penile cancer mortality, incidence, and place of death across all demographics.

Materials And Methods: Using the CDC WONDER database, penile cancer-specific mortality (PNCSM) trends in the US were evaluated from 1999 to 2020 by race/ethnicity, age group, census region, and place of death.

Oculomics analysis in multiple sclerosis: Current ophthalmic clinical and imaging biomarkers.

Multiple Sclerosis (MS) is a chronic autoimmune demyelinating disease of the central nervous system (CNS) characterized by inflammation, demyelination, and axonal damage. Early recognition and treatment are important for preventing or minimizing the long-term effects of the disease. Current gold standard modalities of diagnosis (e.

Association between COVID-19 vaccination and stroke: a nationwide case-control study in Qatar.

Objective: This study investigated the association between Coronavirus Disease 2019 mRNA vaccination and stroke in Qatar.

Methods: Between December 1, 2020, and April 11, 2023, a matched case-control study was conducted to investigate the association between 3036 acute stroke cases and 3036 controls drawn from the entire population of Qatar.

Results: The adjusted odds ratio (aOR) for vaccination among cases compared to controls was 0.

Generative artificial intelligence in ophthalmology.

Generative artificial intelligence (AI) has revolutionized medicine over the past several years. A generative adversarial network (GAN) is a deep learning framework that has become a powerful technique in medicine, particularly in ophthalmology for image analysis. In this paper we review the current ophthalmic literature involving GANs, and highlight key contributions in the field.

Short-term functional outcomes of patients with acute intracerebral hemorrhage in the native and expatriate population.

Objectives: Functional outcomes in patients with intracerebral hemorrhage (ICH) have not been well characterized in the Middle East and North Africa Region. We report the 30 and 90-day clinical outcomes in the native and expatriate of Qatar with ICH.

Methods: We evaluated the Glasgow Coma Scale (GCS), NIHSS, and imaging in the Qatar Stroke Registry (2013-22).

Prognostic Significance of Immune Cell Infiltration in Muscle-invasive Bladder Cancer Treated with Definitive Chemoradiation: A Secondary Analysis of RTOG 0524 and RTOG 0712.

Chemoradiation therapy (CRT) is a treatment for muscle-invasive bladder cancer (MIBC).
