Possible effects of radiofrequency electromagnetic radiation on contextual fear conditioning, hippocampal perivascular space, apoptosis and adrenal gland microarchitecture in rats.

Whilst the world sees the tremendous growth of mobile phone technology, radiofrequency electromagnetic radiation (RF-EMR) induced possible health effects have emerged as a topic of recent day debate. The current study is designed to test the hypothesis that chronic 900MHz radiation exposure would potentially dysregulate the stress response system (HPA axis) in vivo, via, its non-thermal mechanisms, leading to alterations in the microarchitecture of the adrenal gland, vulnerable brain regions such as the hippocampus which may results in altered behaviours in rats. Male albino Wistar rats aged four weeks, weighing 50-60g were subjected to 900MHz radiation from a cellphone for four weeks at a rate of one hour per day.

Time-varying analyses of survival and outcomes in patients with HeartMate 3 left ventricular assist devices.

Aims: As patients experience longer survival on HeartMate 3 left ventricular assist devices, there is a need to characterize long-term risks of adverse outcomes more precisely. This study characterized temporal variations in risks of mortality and adverse outcomes in patients with a HeartMate 3.

Methods And Results: From October 2015 to January 2023, 431 HeartMate 3 devices were implanted at Cleveland Clinic.

Parameter-efficient fine-tuning of large language models using semantic knowledge tuning.

Large Language Models (LLMs) are gaining significant popularity in recent years for specialized tasks using prompts due to their low computational cost. Standard methods like prefix tuning utilize special, modifiable tokens that lack semantic meaning and require extensive training for best performance, often falling short. In this context, we propose a novel method called Semantic Knowledge Tuning (SK-Tuning) for prompt and prefix tuning that employs meaningful words instead of random tokens.

Microbial Evaluation of Plaque on Conventional Stainless Steel Crown and Titanium-coated Stainless Steel Crown on Primary Molars.

Introduction: The extensive plaque formation on dental restoratives may contribute to secondary caries or periodontal inflammation. Therefore, it is important to know how different types of dental restoratives may prevent or promote the accumulation of microorganisms. Hence, this study aims to evaluate the oral hygiene and microbial adhesion on the titanium (Ti)-coated stainless steel crown (Ti-coated SSC) and conventional SSC on a primary molar.
