Cisplatin (CP) is a widely used chemotherapeutic agent that elicits severe gastrointestinal toxicity. Nigella sativa, a member of family Ranunculaceae, is one of the most revered medicinal plant known for its numerous health benefits. Thymoquinone (TQ), a major bioactive component derived from the volatile oil of Nigella sativa seeds, has been shown to improve gastrointestinal functions in animal models of acute gastric/intestinal injury. In view of this, the aim of the present study was to investigate the protective effect of TQ on CP induced toxicity in rat intestine and to elucidate the mechanism underlying these effects...

Leishmania donovani causes cutaneous leishmaniasis (CL) in Sri Lanka. Standard treatment is multiple, painful doses of intralesional sodium stibogluconate (IL-SSG). Treatment failures are increasingly reported, hence the need to investigate alternatives. Efficacy, safety, and cost-effectiveness of thermotherapy were assessed for the first time for L. donovani CL. A single blinded noninferiority randomized controlled trial was conducted on new laboratory-confirmed CL patients with single lesions (N = 213). Selected patients were randomly assigned to 1) test group (N = 98; single session of radiofrequency-induced heat therapy (RFHT) given at 50°C for 30 seconds) and 2) control group (N = 115; 1-3 mL IL-SSG given weekly, until cure/10 doses)...

Exposure to pesticides like paraquat (PQ) is considered as a risk factor for Parkinson's disease (PD). PQ has been shown to induce PD-like phenotype in experimental animals. Drosophila, a valuable laboratory model organism, is widely used to study neurodegenerative disorders including PD. The acute (single dose) PQ model of PD in Drosophila is associated with high mortality as well as reversibility of locomotor deficits and, therefore, does not replicate the disease phenotype. We have investigated the relevance of the acute and multiple (sublethal) dose of PQ to induce PD-like symptoms in Drosophila and shown that multiple-dose of PQ induces irreversible locomotor impairment without significant mortality...

Temporary parent vessel clip occlusion in aneurysm surgery is not always practical or feasible. Adenosine-induced transient cardiac arrest may serve as an alternative. We retrospectively reviewed our clinical database between September 2011 and July 2014. All patients who underwent microsurgical clipping of intracranial aneurysms under adenosine-induced asystole were included. A total of 18 craniotomies were performed, and 18 aneurysms were clipped under adenosine-induced asystole (7 basilar arteries, 8 internal carotid arteries, 1 middle cerebral artery, and 1 anterior communicating artery) in 16 patients (10 females, 6 males)...

BACKGROUND: Interferons are natural messenger proteins that are used to treat various disease entities. Due to their immunomodulating, antiviral and antiproliferative effects, the systemic administration of interferons after ablative treatment for anogenital warts (AGWs) has been advocated to increase clearance and decrease recurrence rates. However, studies investigating the efficacy of adjuvant systemic interferon have yielded inconsistent results. The objective of this systematic review and meta-analysis was to comprehensively assess and evaluate the available evidence from randomised controlled trials...

BACKGROUND: As irradiated brain volume at 12 Gy (V12) is a predictor for radionecrosis, the purpose of the study was to develop a model for Cyberknife (CK) plans that is able to predict the lowest achievable V12 at a given tumor size and prescription dose (PD), and to suggest a new quality index regarding V12 for optimizing the treatment planning of brain metastases. METHOD: In our model V12 was approximated as a spherical shell around the tumor volume. The radial distance between tumor surface and the 12 Gy isodose line was calculated using an approximation of the mean dose gradient in that area...

The Middle East respiratory syndrome coronavirus (MERS-CoV) is a zoonotic betacoronavirus that was first detected in humans in 2012 as a cause of severe acute respiratory disease. As of July 28, 2017, there have been 2,040 confirmed cases with 712 reported deaths. While many infections have been fatal, there have also been a large number of mild or asymptomatic cases discovered through monitoring and contact tracing. New Zealand white rabbits are a possible model for asymptomatic infection with MERS-CoV. In order to discover more about non-lethal infections and to learn whether a single infection with MERS-CoV would protect against reinfection, we inoculated rabbits with MERS-CoV and monitored the antibody and inflammatory response...
