BACKGROUND/AIMS: The increasing prevalence of ionizing radiation exposure has inevitably raised public concern over the potential detrimental effects of ionizing radiation on male reproductive system function. The detection of drug candidates to prevent reproductive system from damage caused by ionizing radiation is urgent. We aimed to investigate the protective role of taurine on the injury of mouse spermatocyte-derived cells (GC-2) subjected to ionizing radiation. METHODS: mouse spermatocytes (GC-2 cells) were exposed to ionizing radiation with or without treatment of Taurine...

The underlying pathophysiology of liver dysfunction in urea cycle disorders (UCDs) is still largely elusive. There is some evidence that the accumulation of urea cycle (UC) intermediates are toxic for hepatocyte mitochondria. It is possible that liver injury is directly caused by the toxicity of ammonia. The rarity of UCDs, the lack of checking of iron level in these patients, superficial knowledge of UC and an underestimation of the metabolic role of fumaric acid, are the main reasons that are responsible for the incomprehension of the mechanism of liver injury in patients suffering from UCDs...

BACKGROUND: Female genital tuberculosis (FGTB) is a Mycobacterium infection in the reproductive organs which often leads to infertility. FGTB is either asymptomatic or causes uncharacteristic clinical presentations, making an early diagnosis is challenging. Our aims were to evaluate the clinical presentations, the process to confirm the diagnosis and followed-up the patients who had undergone laparoscopy at our center. FGTB has been reported from many countries, but has never been reported from Indonesia...

BACKGROUND: Despite reductions in youth pedestrian and bicyclist deaths over the past two decades, these injuries remain a substantial cause of morbidity and mortality for children and adolescents. There is a need for additional information on non-fatal pediatric pedestrian injuries and the role of traumatic brain injury (TBI), a leading cause of acquired disability. METHODS: Using a multi-year national sample of emergency department (ED) records, we estimated annual motorized-vehicle related pediatric pedestrian and bicyclist (i...

CONTEXT: For most programs, whether funded through governmental agencies or nongovernmental organizations, demonstrating the impact of implemented activities is vital to ensuring continued funding and support. OBJECTIVE: Program evaluation is a critical tool that serves the dual purpose of describing impact and identifying areas for program improvement. From a funder's perspective, describing the individual and collective impact of state-based programs can be challenging due to variations in strategies being implemented and types of data being collected...

Crescentic rapidly progressive glomerulonephritis (RPGN) represents the most aggressive form of acquired glomerular disease. While most therapeutic approaches involve potentially toxic immunosuppressive strategies, the pathophysiology remains incompletely understood. Podocytes are glomerular epithelial cells that are normally growth-arrested because of the expression of cyclin-dependent kinase (CDK) inhibitors. An exception is in RPGN where podocytes undergo a deregulation of their differentiated phenotype and proliferate...

Cellular senescence is a fundamental cell fate caused by several cellular injuries which results in irreversible cell cycle arrest yet remaining metabolically active across all species. Cellular senescence not only can prevent tumor occurrence by inhibiting the proliferation of injured cells, but also can affect the surrounding cells through the senescence-associated secretory phenotype (SASP). Attractively, accumulating evidence shows that cellular senescence is closely related to various liver diseases. Therapeutic opportunities based on targeting senescent cells and the SASP are considered to be potential strategy for liver diseases...

Normal wound healing is accomplished through a series of well-coordinated, progressive events with overlapping phases. Chronic wounds are described as not progressing to healing or not being responsive to management in a timely manner. A consensus panel of multidisciplinary wound care professionals was assembled to (1) educate wound care practitioners by identifying key principles of the basic science of chronic wound pathophysiology, highlighting the impact of metalloproteinases and biofilms, as well as the role of the extracellular matrix; and (2) equip practitioners with a systematic strategy for the prevention and healing of acute injuries and chronic wounds based upon scientific evidence and the panel members' expertise...

Tissue hypoxia has been proposed as an important factor in the pathophysiology of both chronic kidney disease and acute kidney injury, initiating and propagating a vicious cycle of tubular injury, vascular rarefaction, and fibrosis and thus exacerbation of hypoxia. Here, we critically evaluate this proposition by systematically reviewing the literature relevant to the following six questions: (1) Is kidney disease always associated with tissue hypoxia? (2) Does tissue hypoxia drive signaling cascades that lead to tissue damage and dysfunction? (3) Does tissue hypoxia per se lead to kidney disease? (4) Does tissue hypoxia precede pathology? (5) Does tissue hypoxia co-localize with pathology? (6) Does prevention of tissue hypoxia prevent kidney disease? We conclude that tissue hypoxia is a common feature of both acute kidney injury and chronic kidney disease...

BACKGROUND: Connexin43 hemichannels have been implicated in many inflammatory diseases including diabetic retinopathy (DR). Particularly, hemichannel-mediated ATP release has been associated with inflammasome pathway activation. Using an in vitro cell culture model, we evaluated hemichannel roles in response to inflammatory cytokines under high glucose (HG) conditions and propose a mechanism by which a connexin43 hemichannel-mediated autocrine ATP feedback loop augments chronic inflammatory disease...

Functional electrical stimulation cycling has been proposed as an assistive technology with numerous health and fitness benefits for people with spinal cord injury, such as improvement in cardiovascular function, increase in muscular mass, and reduction of bone mass loss. However, some limitations, for example, lack of optimal control strategies that would delay fatigue, may still prevent this technology from achieving its full potential. In this work, we performed experiments on a person with complete spinal cord injury using a stationary tadpole trike when both cadence tracking and disturbance rejection were evaluated...

Hemorrhage‑related neurologic injury is a primary cause of disability and mortality following subarachnoid hemorrhage (SAH). The aim of the present study was to investigate the potential neuroprotective effect and the possible role of autophagy in limb remote ischemic post‑conditioning (RIPostC) using an endovascular puncture rat model of SAH. RIPostC was induced by three cycles of occlusion (10 min) and release (10 min) in the bilateral femoral artery using an aneurysm clip. Early RIPostC began immediately following SAH, delayed RIPostC began following a 30 min delay and the repeated RIPostC group underwent the protocol every day for 3 days...

Police crash reports are often the main source for official data in many countries. However, with the exception of fatal crashes, crashes are often underreported in a biased manner. Consequently, the countermeasures adopted according to them may be inefficient. In the case of bicycle crashes, this bias is most acute and it probably varies across countries, with some of them being more prone to reporting accidents to police than others. Assessing if this bias occurs and the size of it can be of great importance for evaluating the risks associated with bicycling...

Multiple sclerosis (MS) is a chronic autoimmune inflammatory disease of the central nervous system (CNS), characterized by demyelination, neuronal injury, and breaching of the blood-brain barrier (BBB). Epidemiological studies have shown that immunological, genetic, and environmental factors contribute to the progression and development of MS. T helper 17 (Th17) cells are crucial immunological participant in the pathophysiology of MS. The aberrant production of IL-17 and IL-22 by Th17 cells crosses BBB promotes its disruption and interferes with transmission of nerve signals through activation of neuroinflammation in the CNS...

BACKGROUND: Regorafenib (Stivarga) is an oral multikinase inhibitor currently approved for patients with metastatic colorectal cancer or gastrointestinal stromal tumor. Although hepatotoxicity has been a known product profile feature of regorafenib since its initial approval, its clinical features are limited to those found in the clinical trials. PATIENTS AND METHODS: The present study was conducted in 2 analysis sets: a safety analysis set for metastatic colorectal cancer from solicited postmarketing surveillance (PMS) in Japan (n = 1227) and an analysis set for serious hepatic adverse drug reactions (n = 210) from all patients registered for regorafenib use...

After peripheral nerve injury, there are important changes at the spinal level that can lead to disorganization of the central circuitry and thus, compromise functional recovery even if axons are able to successfully regenerate and reinnervate their target organs. Physical rehabilitation is a promising strategy to modulate these plastic changes and thus, to improve functional recovery after damage of the nervous system. Forced exercise in a treadmill is able to partially reverse the synaptic stripping and the loss of perineuronal nets that motoneurons suffer after peripheral nerve injury in animal models...

INTRODUCTION: Recently, there has been increasing interest in the preoperative prediction and prevention of post-hepatectomy liver failure (PHLF). This is a particular concern in colorectal liver metastases (CRLM), when surgery follows potentially hepatotoxic chemotherapy. Platelet-based liver scores (PBLS) such as APRI and FIB-4 are predictive of chemotherapy-associated liver injury (CALI) and PHLF. Estimation of the future liver remnant function (eFLRF) by combining (99m)Tc-Mebrofenin Hepatobiliary Scintigraphy (HBS(BSA)) with future liver remnant volume ratio (FLRV%), is predictive of PHLF and related mortality...
