BF·EtO-promoted unconventional reactions of 2-oxoaldehyde: access to 4-amidooxazoles and β-keto amides/sulphonamides.

This study investigates the potential of boron trifluoride etherate (BF·OEt) to trigger unprecedented reactions of 2-oxoaldehydes with nitriles and amides/sulphonamides. In contrast to the mechanism in conventional reactions, the α-carbonyl group in 2-oxoaldehydes induces a cyclization pathway to be followed when reacting with nitriles, yielding 4-amidooxazoles. Additionally, reactions with weak nucleophiles produce β-keto amides/sulphonamides.

Acute Kidney Injury Post Hip Fracture Surgery: Local Quality Improvement Project and Review of Literature.

Background:  The aim of the study is to identify the potential risk factors for postoperative AKI in hip fracture patients.

Design And Methods:  Using our local neck of femur (NOF) registration data, patient details were selected using inclusion and exclusion criteria. Electronic records of patients were assessed retrospectively, including blood results, radiological investigations, clinical documentation, and drug charts.

Ultrasound-Guided Intraosseous Injection of Bone Marrow Aspirate Concentrate for a Basketball Player With Bilateral Tibial Nonunion Fractures.

We present a case of a professional basketball player who suffered from nonunion bilateral chronic tibial fractures, successfully treated with ultrasound-guided intraosseous injection with bone marrow aspirate concentrate. The patient was able to return to play full time after recovery from the procedure.

Did Primary Healthcare Patients in Riyadh Experience Their First Migraine Episodes After a Stressful Event, and What Triggers and Relievers Do They Commonly Report?

Objective: This study aimed to investigate whether the first onset of migraine episodes among primary healthcare patients in Riyadh, Saudi Arabia, is preceded by a highly stressful event, as well as to identify common potential triggers and relievers reported by these patients.

Background: Migraine is a prevalent and debilitating neurological disorder. The pathophysiology of migraine involves complex interactions between genetic, neurological, and environmental factors, including the trigeminovascular system and neuropeptides such as calcitonin gene-related peptide (CGRP).

Endophytic fungi: nature's solution for antimicrobial resistance and sustainable agriculture.

The growing threat of antimicrobial resistance (AMR) has underlined the need for a sustained supply of novel antimicrobial agents. Endophyte microorganism that reside within plant tissues as symbionts have been the source of potential antimicrobial substances. However, many novel and potent antimicrobials are yet to be discovered from these endophytes.
