IMPROVEMENT OF COGNITIVE FUNCTION IN WISTAR RATS UNDER CHRONIC STRESS CONDITIONS WITH MELATONIN.

Stress is a significant factor affecting cognitive functions such as memory, attention and learning ability. This paper examined the effects of melatonin at different dosages on cognitive performance compared to choline alphoscerate on wistar line rats under chronic stress conditions. The studied rats were subjected to stress - Porsolt's forced swim test.

Adherence to Preoperative Fasting Guidelines in Elective Surgical Patients.

Introduction: Preoperative fasting is recommended by international guidelines as a means to minimize the risk of aspiration of gastric content during induction of anesthesia or surgery. Prolonged preoperative fasting is, however, discouraged due to the associated side effects such as dehydration and electrolyte imbalance, which can negatively impact recovery after surgery. An initial quality improvement study revealed poor implementation of the best practice guidelines on preoperative fasting in three departments of a hospital and an institutional action plan was devised to enforce adherence to these guidelines.

Application of Artificial Intelligence in Cardiology: A Bibliometric Analysis.

Recent advancements in artificial intelligence (AI) applications in medicine have been significant over the past 30 years. To monitor current research developments, it is crucial to examine the latest trends in AI adoption across various medical fields. This bibliometric analysis focuses on AI applications in cardiology.

Matrix-assisted laser desorption/ionization matrix incorporation evaluation algorithm for improved peak coverage and signal-to-noise ratio in mass spectrometry imaging.

Rationale: Despite decades of implementation, the selection of optimal sample preparation conditions for matrix-assisted laser desorption/ionization (MALDI) imaging is still ambiguous due to the lack of a universal and comprehensive evaluation methodology. Thus, numerous experiments with different matrix application conditions accompany a translation of the method to novel sample types and matrices.

Methods: Mouse brain tissues were covered with 9-aminoacridine through sublimation, followed by recrystallization in vapors of 5% (v/v) methanol solution in water.

Ac-DEVD-CHO (caspase-3/DEVDase inhibitor) suppresses self-incompatibility-induced programmed cell death in the pollen tubes of petunia (Petunia hybrida E. Vilm.).

Programmed cell death (PCD) is relevant to many aspects in the growth and development of a plant organism. In their reproduction, many flowering plant species possess self-incompatibility (SI), that is an intraspecific reproductive barrier, which is a genetic mechanism ensuring the avoidance of inbreeding depression by preventing self-pollination. This phenomenon enhances intraspecific variation; however, SI is rather a hindrance for some fruit plant species (such as plum, cherry, and peer trees) rather than an advantage in farming.
