Combined effects of climate stressors and soil arsenic contamination on metabolic profiles and productivity of rice (Oryza sativa L.).

Rice productivity and quality are increasingly at risk in arsenic (As) affected areas, challenge that is expected to worsen under changing climatic conditions. Free-Air Concentration Enrichment experiments revealed that eCO, eO, and eTemp, whether acting individually or in combination with low and high As irrigation, significantly impact rice yield and grain quality. Elevated CO₂ significantly increased shoot biomass, with minimal impact on root biomass, except under low As irrigation conditions.

Transient apical breakdown associated with clear aligner therapy: a case report.

Transient apical breakdown (TAB) is widely reported in response to trauma, yet its occurrence due to orthodontic forces, particularly in aligner therapy, is less documented within current literature. TAB can easily be misdiagnosed as pulp necrosis, potentially leading to unnecessary and irreversible endodontic procedures. This case report describes an instance of TAB following the initiation of aligner treatment, where the affected tooth initially presented with signs suggesting pulp necrosis but regained normal coloration and pulpal response after six months of active monitoring.

Predicting mortality after transcatheter aortic valve replacement using AI-based fully automated left atrioventricular coupling index.

Background: This study aimed to determine whether artificial intelligence (AI)-based automated assessment of left atrioventricular coupling index (LACI) can provide incremental value above other traditional risk factors for predicting mortality among patients with severe aortic stenosis (AS) undergoing coronary CT angiography (CCTA) before transcatheter aortic valve replacement (TAVR).

Methods: This retrospective study evaluated patients with severe AS who underwent CCTA examination before TAVR between September 2014 and December 2020. An AI-prototype software fully automatically calculated left atrial and left ventricular end-diastolic volumes and LACI was defined by the ratio between them.

A Gas Chromatography-Mass Spectrometry Method to Determine Tramadol Abuse Using Urine Samples.

Background The synthetic opioid tramadol is widely used as a pain reliever. Unlike other opioids, it is used freely worldwide, unaffected by international controls resulting in abuse and accidental intoxication. Analytical methods are necessary to prove tramadol abuse because 30% of the drug is excreted unchanged.
