Structure of a zoonotic H5N1 hemagglutinin reveals a receptor-binding site occupied by an auto-glycan.

Highly pathogenic avian influenza has spilled into many mammals, most notably cows and poultry, with several dozen human breakthrough infections. Zoonotic crossovers, with hemagglutinins mutated to enhance viral ability to use human α2-6-linked sialic acid receptors versus avian α2-3-linked ones, highlight the pandemic risk. To gain insight into these crossovers, we determined the cryoelectron microscopy (cryo-EM) structure of the hemagglutinin from the zoonotic H5N1 A/Texas/37/2024 strain (clade 2.

Impaired Resting State Functional Connectivity in CADASIL Mutant Mice.

Cerebral autosomal-dominant arteriopathy, subcortical infarcts, and leukoencephalopathy (CADASIL) is the most prevalent monogenic inherited cause of cerebral small-vessel disease. Despite its prevalence, there is currently no proven therapy to prevent or reverse the progression of the disease. This study aimed to characterize the functional integrity of long white matter tracts in CADASIL transgenic mice, both with and without focal white matter lesions in the corpus callosum added on, utilizing optical resting-state functional connectivity imaging alongside behavioral examinations.

ALS Motor Observational Telemedicine Objective Rasch-Built Assessment: A Quantitative Scale for the Era of Teleneurology.

Background And Objectives: Telemedicine has become a mainstay of ALS clinical care, but there is currently no standardized approach for assessing and tracking changes to the neurologic examination in this format. The goal of this study was to create a standardized telemedicine-based motor examination scale to objectively and reliably track ALS progression and use Rasch methodology to validate the scale and improve its psychometric properties.

Methods: A draft telemedicine examination scale with 25 items assessing movement in the bulbar muscles, neck, trunk, and extremities was created by an ALS expert panel, incorporating input from patient advisors.

Eco-friendly extraction and recovery of triterpenoids from persimmon leaves ( L.f.) using ultrasound-assisted deep eutectic solvents and macroporous resins.

Triterpenoids are known for their promising biological activities, and there is a growing focus on green extraction methods for these compounds. In this study, ultrasound-assisted deep eutectic solvents were employed to extract triterpenoids from persimmon leaves, with choline chloride-lactic acid identified as an effective green solvent. The extraction conditions were carefully optimized using response surface methodology, resulting in an extraction efficiency of 12.

Feasibility and accuracy of continuous intraabdominal pressure monitoring with a capsular device in human pilot trial.

Background: Intrabdominal pressure (IAP) is an important parameter. Elevated IAP can reduce visceral perfusion, lead to intraabdominal hypertension, and result in life-threatening abdominal compartment syndrome. While ingestible capsular devices have been used for various abdominal diagnoses, their application in continuous IAP monitoring remains unproven.
