Hydrogen cyanamide poisoning: multiple microscopic analyses evidence of forensic entomotoxicology succession on decomposing covered/uncovered rat carrions

Research Abstract
Background
Forensic entomotoxicology is a crucial field that studies the effects of drugs and poisons on carrion-feeding insects, particularly in crime investigations. Hydrogen cyanamide, a plant growth regulator, is hazardous and used in agriculture but is limited in some countries due to its high cost and severe toxicity. The terrestrial isopod Porcellio laevis plays a vital role in soil ecosystems and biosystem management. Accordingly, authors aimed to examine the impact of hydrogen cyanamide toxicity on arthropods, specifically Porcellio laevis, Musca domestica (House flies), and Sarcophaga sp. (Flesh flies) visiting decomposing covered/uncovered rat carrions, which could be relevant in forensic investigations. A total of 20 rats were divided into two control (I and II, covered/uncovered) and two treated groups (III and IV, covered/uncovered, euthanized using hydrogen cyanamide). Arthropods were gathered bi-daily …

Do we need a small catheter drainage with chest tube after uniportal video-assisted thoracoscopic surgery for better drainage?

Research Abstract
Materials and Methods: It represents a pilot prospective study randomized trial from August 2019 to August 2020 who had undergone uniportal VATS procedures were divided into two groups as group A (chest tube with small catheter) and group B (chest tube only).
Results: Fifty-three patients underwent uniportal VATS only 30 where eligible to the study divided into two equal groups (18 males, 12 females). The mean age of patients in the small catheter with chest tube was 42.07±12.85 years, compared to 34.93±10.73 years in the chest tube only. Six different types of operation was done. Postoperative pain and hospital stays was nearly equal in both groups (p> 0.05). Postoperative residual effusion in immediate chest x-ray in small catheter with chest tube was managed by aspiration from small catheter and show improvement in follow up chest x-ray next morning (p< 0.05) but in chest tube only was management conservatively didn’t show improvement in follow up chest x-ray next morning (p> 0.05).
Conclusions: Small catheter with chest tube didn’t add more pain. Although more than half of the cases get aspiration from small catheter and show improvement in follow up chest x-ray next morning, this does not statically affect hospital stay.

Comparative study of aortic root replacement versus aortic root enlargement in small aortic root

Research Abstract
For patients with aortic stenosis (AS) and small annulus, aortic root replacement (RR) and aortic root enlargement (RE) are proven methods to prevent prosthesis-patient mismatch (PPM). Our goal was to compare the results of those two categories of operations. This prospective study used our hospitals’ database of aortic valve replacements from 2021 to 2024. Patients who had aortic stenosis treated with RE or RR were compared. The postoperative results and reoperations were compared. Kaplan–Meier survival estimation and log-rank test were used to compare time-to-event data.
Results
A total of 72 patients had aortic stenosis treated with either RE or RR. Thirty-eight (52%) and 34 (47%) patients underwent RR and RE, respectively. In RR cases, significant postoperative bleeding was noted in 13 patients vs. only 4 patients in RE group (P-value = 0.001). The length of stay did not differ …

Effect of ostarine on glucose level, lipid profile, and osteoporosis in streptozotocin induced diabetic male rats

Research Abstract

This study aimed to evaluate ostarine effects on blood glucose, dyslipidemia, and osteoporosis in diabetic rats. Forty-eight adult male rats were divided into six groups (Control, Ostarine: 0.4 mg/kg daily orally, diabetes mellitus (DM), DO: diabetic rats received ostarine, DI: diabetic rats received insulin, DOI: diabetic rats received ostarine and insulin for 8 weeks). Radiographic examination for bone was done. Blood samples, bone, and pancreas were taken for examination. Ostarine significantly increased body weight, muscle weight, bone weight and ashing, lowered blood glucose, TC, low-density lipoprotein-cholesterol (LDL-C), and triglycerides, increased Ca++, phosphorus (P), osteocalcin, RUNX2, and positive immunostained osteopontin cells compared to DM, but no significance on CTX-I or RANKL. It improved bone density in X-ray, pancreatic islet cells and bone microarchitecture in histological examinations …
