Melatonin induces drought stress tolerance by regulating the physiological mechanisms, antioxidant enzymes, and leaf structural modifications in L.

Melatonin is considered an effective bio-stimulant that is crucial in managing several abiotic stresses including drought. However, its potential mechanisms against drought stress in fragrant roses are not well understood. Here, we aim to investigate the role of melatonin on plants cultivated under drought stress (40 % field capacity) and normal irrigation (80 % field capacity).

Efficient and Accurate Brain Tumor Classification Using Hybrid MobileNetV2-Support Vector Machine for Magnetic Resonance Imaging Diagnostics in Neoplasms.

Background/objectives: Magnetic Resonance Imaging (MRI) plays a vital role in brain tumor diagnosis by providing clear visualization of soft tissues without the use of ionizing radiation. Given the increasing incidence of brain tumors, there is an urgent need for reliable diagnostic tools, as misdiagnoses can lead to harmful treatment decisions and poor outcomes. While machine learning has significantly advanced medical diagnostics, achieving both high accuracy and computational efficiency remains a critical challenge.

Regulation of physiological and pathological condensates by molecular chaperones.

Biomolecular condensates are dynamic membraneless compartments that regulate a myriad of cellular functions. A particular type of physiological condensate called stress granules (SGs) has gained increasing interest due to its role in the cellular stress response and various diseases. SGs, composed of several hundred RNA-binding proteins, form transiently in response to stress to protect mRNAs from translation and disassemble when the stress subsides.

Right atrial reverse remodeling and risk of atrial arrhythmias after surgical pulmonary valve replacement.

Background: Right atrial (RA) dysfunction and atrial arrhythmias are relatively common in adults with repaired tetralogy of Fallot. The purpose of this study was to determine whether RA function improved after surgical pulmonary valve replacement (PVR), and the association between postoperative RA reverse remodeling and late postoperative atrial arrhythmias.

Method: RA reverse remodeling (ΔRA reservoir strain based speckle tracking echocardiography) was calculated as: ([postoperative RA reservoir strain - preoperative RA reservoir strain]/preoperative RA reservoir strain)x100.

Asymptomatic Peripheral Arterial Disease Among Jordanian Patients With Diabetic Foot Ulcer.

Background and objective Peripheral arterial disease (PAD) is a common disorder that is usually associated with leg symptoms such as intermittent claudication (IC), which could be masked by peripheral neuropathy in diabetic patients. In this study, we aimed to assess the prevalence and associated risk factors of asymptomatic PAD among Jordanian patients with diabetic foot ulcers. Methods A cross-sectional study involving diabetic foot patients attending the diabetic foot clinic at the Medical City in Royal Medical Services in Amman, Jordan, was conducted from January 2023 to March 2024.
