Redox processes can modulate vascular pathophysiology. The endoplasmic reticulum redox chaperone protein disulfide isomerase A1 (PDIA1) is overexpressed during vascular proliferative diseases, regulating thrombus formation, endoplasmic reticulum stress adaptation, and structural remodeling. However, both protective and deleterious vascular effects have been reported for PDIA1, depending on the cell type and underlying vascular condition. Further understanding of this question is hampered by the poorly studied mechanisms underlying PDIA1 expression regulation...

BACKGROUND: Paucity of deceased donor livers has resulted in a 10-fold rise in living donor liver transplantations (LDLTs) performed in India over the past decade. Nonetheless, number of deceased donor liver transplantation (DDLT) performed has improved with the establishment of simplified legal framework for certification of brain death and organ donation. In this study, we present our outcomes of DDLT performed at various centers, comparing their outcomes and provide a snapshot of the increasing number of DDLT across the state over the years...

Patterns in parasite diversity are shaped by their environmental and ecological settings, and to better understand their interactions with hosts and the corresponding biology, it is crucial to understand these context-dependent patterns. To achieve this, we use cymothoid isopods, an important group of fish parasites, to test a long-standing hypothesis about parasite diversity and prevalence pattern: whether semi-enclosed water bodies allow low diversity and high prevalence of parasitic isopods. Specifically, we compare these patterns between Chilika lagoon (Odisha, India), a semi-enclosed water body, and the adjoining Odisha coast (India)...

OBJECTIVE: Pediatric Heart-lung transplant (HLTX) is performed for endstage congenital heart disease (CHD) with irreversible pulmonary hypertension or non-congenital heart disease (NCHD) with end-stage heart and lung disease. CHD could influence the outcomes of HTLX due to increased complexity of the operation as compared to NCHD. In this study we evaluated the influence of cardiac diagnosis on outcomes of pediatric HTLX. METHODS: The UNOS database (1987-2022) was queried for primary HTLX in patients <18 years...

Strain sensors are sensitive to mechanical deformations and enable the detection of strain also within integrated electronics. For flexible displays, the use of a seamlessly integrated strain sensor would be beneficial, and graphene is already in use as a transparent and flexible conductor. However, graphene intrinsically lacks a strong response, and only by engineering defects, such as grain boundaries, one can induce piezoresistivity. Nanocrystalline graphene (NCG), a derivative form of graphene, exhibits a high density of defects in the form of grain boundaries...

The study presents a novel, one-pot, and scalable solid-state reaction scheme to prepare bismuth sulphide (Bi2 S3 )-reduced graphene oxide (rGO) nanocomposites using bismuth oxide (Bi2 O3 ), thiourea (TU), and graphene oxide (GO) as starting materials for energy storage applications. The impact of GO loading concentration on the electrochemical performance of the nanocomposites was investigated. The reaction follows a diffusion substitution pathway, gradually transforming Bi2 O3 powder into Bi2 S3 nanostrips, concurrently converting GO into rGO...

INTRODUCTION: Total hip arthroplasty (THA) for dislocated hips (Crowe IV dysplasia) presents unique challenges. Conventional approaches involve subtrochanteric osteotomies, but are complex with additional fixation and potentially lead to limb-length discrepancies, nerve palsies, and other complications. An alternative strategy is a staged approach, where the femoral head (or remnant) is gradually lowered (distraction technique) to align with the true acetabulum over a period of time, followed by a second-stage anatomically acetabular-positioned THA...

OBJECTIVE: The laryngeal adductor reflex (LAR) is vital for airway protection and can be electrophysiologically obtained under intravenous general anesthesia (IGA). This makes the electrophysiologic LAR (eLAR) an important tool for monitoring of the vagus nerves and relevant brainstem circuitry during high-risk surgeries. We investigated the intra-class variability of normal and expected abnormal eLAR. METHODS: Repeated measures of contralateral R1 (cR1) were performed under IGA in 58 patients...

BACKGROUND: Aging-related processes contribute to neurodegeneration and disability in multiple sclerosis (MS). Biomarkers of biological aging such as leukocyte telomere length (LTL) could help personalise prognosis. Pregnancy has been shown to be protective against disability accumulation in women with MS, though it is unclear if this effect relates to aging mechanisms or LTL. OBJECTIVES: This study aimed to cross-sectionally characterise LTL in a cohort of individuals with MS, and to correlate LTL with disability severity and pregnancy history...

This retrospective cohort study included 77 mother-infant dyads that delivered term pregnancies at a single tertiary care institution. The primary objective was to investigate whether maternal dose of opioid maintenance therapy during pregnancy affects infant outcomes. All infants had prenatal exposure to opioid maintenance therapies. Maternal dose was converted into morphine milligram equivalents (MMEs) and stratified into high- (MME >1000 mg) and low-dose groups (MME ≤1000 mg). Associations between infant outcomes and MME dosage were examined using Wilcoxon rank-sum and Fisher's Exact tests...

Hematologic toxicity frequently complicates chimeric antigen receptor (CAR) T-cell therapy, resulting in significant morbidity and mortality. In an effort to standardize reporting, the European Hematology Association (EHA) and European Society of Blood and Marrow Transplantation (EBMT) devised the immune effector cell-associated hematotoxicity (ICAHT) grading system, distinguishing between early (day 0-30) and late (after day +30) events based on neutropenia depth and duration. However, manual implementation of ICAHT grading criteria is time-consuming and susceptible to subjectivity and error...

Brain tumor glioblastoma is a disease that is caused for a child who has abnormal cells in the brain, which is found using MRI "Magnetic Resonance Imaging" brain image using a powerful magnetic field, radio waves, and a computer to produce detailed images of the body's internal structures it is a standard diagnostic tool for a wide range of medical conditions, from detecting brain and spinal cord injuries to identifying tumors and also in evaluating joint problems. This is treatable, and by enabling the factor for happening, the factor for dissolving the dead tissues...

INTRODUCTION: The use of ChatGPT (Generative Pretrained Transformer), which is a natural language artificial intelligence model, has gained unparalleled attention with the accumulation of over 100 million users within months of launching. As such, we aimed to compare: 1) orthopaedic surgeons' evaluation of the appropriateness of the answers to the most frequently asked patient questions after total hip arthroplasty (THA); and 2) patients' evaluation of ChatGPT and arthroplasty-trained nurses responses to answer their postoperative questions...

Breast cancer continues to pose a substantial global health challenge, emphasizing the critical need for the advancement of novel therapeutic approaches. Key players in the regulation of apoptosis, a fundamental process in cell death, are the B-cell lymphoma 2 (Bcl-2) family proteins, namely Bcl-2 and Bax. These proteins have garnered attention as highly promising targets for the treatment of breast cancer. Targeting the overexpressed anti-apoptotic Bcl-2 protein in breast cancer, Gefitinib (GEF), an EGFR (Epidermal Growth Factor Receptor) inhibitor, emerges as a potential solution...

INTRODUCTION: Given the growing emphasis on patient outcomes, including postoperative complications, in total joint arthroplasty (TJA), investigating the rise of outpatient arthroplasty is warranted. Concerns exist over the safety of discharging patients home on the same day due to increased readmission and complication rates. However, psychological benefits and lower costs provide an incentive for outpatient arthroplasty. The influence of social determinants of health disparities on outpatient arthroplasty remains unexplored...

The COVID-19 pandemic and social distancing measures elevated stress levels globally, exacerbating mental health challenges for people with HIV (PWH). We examined the effect of COVID-19-related stress on mental health among PWH in western Washington, exploring whether social support and coping self-efficacy were protective. Data on COVID-19-related stress, mental health, social support, and coping self-efficacy were collected using online surveys during the pandemic. Pre-COVID-19 mental health data were available for a subset of participants and were linked with the survey data...
