Article Abstract

Selective oxidation of alcohols to aldehydes/ketones has been achieved with the help of 3-mercaptopropionic acid (MPA)-capped CdSe quantum dot (MPA-CdSe QD) and visible light. Visible-light-prompted electron-transfer reaction initiates the oxidation. The thiyl radical generated from the thiolate anion adsorbed on a CdSe QD plays a key role by abstracting the hydrogen atom from the C-H bond of the alcohol (R CH(OH)R ). The reaction shows high efficiency, good functional group tolerance, and high site-selectivity in polyhydroxy compounds. The generality and selectivity reported here offer a new opportunity for further applications of QDs in organic transformations.

Background: Hospital admissions occur frequently in nursing homes and are often preventable. Inappropriate hospitalisations due to nursing home-sensitive conditions pose significant risks to residents, place additional strain on emergency departments and hospitals, and thus lead to substantial healthcare costs. In light of demographic changes- characterised by an aging and increasingly multimorbid nursing home population- combined with ubiquitous lack of health care professionals, new strategies are urgently needed to ensure adequate medical care in nursing homes.

Background: Sacubitril/valsartan is typically prescribed for patients with heart failure and hypertension. We previously reported that sacubitril/valsartan provides comparable blood pressure (BP) reduction and superior tolerability compared to thiazide diuretics. This post hoc study aimed to compare the effects of sacubitril/valsartan and thiazide diuretics in patients with chronic kidney disease (CKD).

Understanding seagrass dynamics is crucial for the effective management and conservation of seagrass meadows. However, such information remains limited for many regions worldwide, including Kuta Mandalika on Lombok Island, Indonesia. This rapidly developing coastal area, which is home to both tourism infrastructure and an international race circuit, hosts extensive seagrass meadows whose condition and dynamics require careful assessment.

Asymmetric volume-mediated buffer control overcomes sensitivity limits in one-pot RAA-CRISPR/Cas12a visual detection.

Rapid, low-cost, and visual nucleic acid detection methods are highly attractive for curbing colistin resistance spread through the food chain. CRISPR/Cas12a combined with recombinase-aided amplification (RAA) offers a one-pot, aerosol-free approach for visual detection. However, traditional one-pot systems often run Cas12a trans-cleavage in a buffer suitable for RAA, thus limiting Cas12a cleavage efficiency.

Blood-based biomarkers (BBMs) have emerged as promising tools to enhance Alzheimer's disease (AD) diagnosis. Despite two-thirds of dementia cases occurring in the Global South, research on BBMs has predominantly focused on populations from the Global North. This geographical disparity hinders our understanding of BBM performance in diverse populations.
