Nanovesicles Derived From Protocorm-Like Bodies Of Dendrobium Officinal Enhance Corneal Epithelial Repair And Reduce Inflammation In Dry Eye Disease Models, Bao Yuqing, Peng Chengyu, Zhang Fenglei, Zheng Yuqiang, Zhang Mingqi, He Wei

Journal of Food and Drug Analysis

Plant-derived nanovesicles (PDNVs) offer a promising, biocompatible therapeutic platform. In this study, we isolatednanovesicles from protocorm-like bodies of Dendrobium officinale (PLBs-NVs) and evaluated their efficacy in dry eyedisease (DED) models. PLBs-NVs protected human corneal epithelial cells against hyperosmotic stress, supportedwound repair, and inhibited inflammation in vitro. In a desiccating stress-induced DED mouse model, topical PLBs-NVstreatment significantly restored tear secretion, reduced corneal epithelial damage, and lowered levels of proinflammatorycytokines. These results suggest that PLBs-NVs are a safe, natural, and effective therapeutic strategy for DED, sup-porting their potential for future clinical translation in ocular surface disorders.

Efficacy Of Pethidine And Tramadol In The Suppression Of Postoperative Shivering: A Comparative Study, Ahmed Jaber Ibrahim, Hussien Ibrahim Hayal, Ahmed R.Y. Al-Sawad, Shahab Abdulla, Ralela Makline

AUIQ Complementary Biological System

Postoperative shivering is a common complication that can affect patient comfort and stability. Pethidine and tramadol are widely used to relieve this symptom, but their relative effectiveness and safety remain under investigation. In this randomized trial, 50 patients (aged 25–35 years) with postoperative shivering were divided into two groups: one group receiving intravenous tramadol (n = 25 patients) and one group receiving pethidine (n = 25 patients). Onset of drug action, vital signs, and side effects were systematically assessed. Pethidine had a significantly faster onset of action than tramadol (12.20 ± 0.35 min vs 7.16 ± 0.28 min, p < 0.001). No significant differences were observed between the two groups regarding body temperature, heart rate, oxygen saturation, or blood pressure (P < 0.05). Side effects, such as dizziness (16% vs. 8%), nausea and vomiting (20% vs. 8%), and nausea alone (48% vs. 20%), were more common and showed a statistically significant increase in the tramadol group. Both drugs were effective in suppressing postoperative tremor, but pethidine demonstrated superior efficacy, a faster onset of action, and a better safety profile. These results confirm pethidine as the recommended choice at an intravenous dose of 0.5 mg/kg.

Faculty Journal Articles

Neuropteran insects display a phenomenon called distance segregation during male meiosis I, where the X and Y chromosomes are unconnected from prometaphase I through anaphase I. Here we investigate chromosome number and patterns of chromosome segregation of a previously unstudied Neuropteran: the green lacewing, Chrysoperla rufilabris (Burmeister, 1839). Testes of male C. rufilabris were isolated and prepared following a chromosome squash method. Living meiosis I spermatocytes were also imaged. The data revealed a chromosome number of 2n=12 in males (2n=10+XY) and evidence of distance segregation of X and Y chromosomes in meiosis I spermatocytes.

Reeds Run Amok: A Practical Guide To Managing Phragmites-Invaded Wetlands, Christine Rohal, Keith Hambrecht, Chad Cranney, Karin M. Kettenring

All Current Publications

Phragmites australis (common reed or simply “phragmites”) is a tall-statured, highly productive wetland grass. It spreads rapidly, often displacing native plants and degrading critical habitat for shorebirds and waterfowl by reducing the availability of nesting, loafing, and foraging areas. Phragmites also consumes large amounts of water, adding pressure to already scarce water resources. Additionally, the accumulation of standing dead biomass can be a fire hazard. Phragmites makes large areas of wetlands inaccessible to both wildlife and humans. This guide provides guidance on managing phragmites.
