Microvirin is a lectin molecule known to have monovalent interaction with glycoprotein gp120. A previously reported high-resolution structural analysis defines the mannobiose-binding cavity of Microvirin. Nonetheless, structure does not directly define the energetics of binding contributions of protein contact residues.

Thus, AxD is a primary astrocyte disease. However, it remains unclear how mutations affect astrocytes and cause AxD pathology.

Despite its prevalence, predicting the severity and outcomes of bronchiolitis remains challenging. Standardized criteria for severity assessment are essential for improving patient care and resource allocation.

Further research is crucial to elucidate these associations and understand their underlying mechanisms.
Abstract: Severe Acute Respiratory Syndrome Coronavirus- 2 (SARS-CoV-2), a positive-sense single-stranded RNA virus, causes COVID-19 and has been linked to autoimmune disorders.
Key Clinical Message: This case emphasizes the need for early recognition and accurate diagnosis of achalasia in young adults to avoid exacerbation of the condition and misdiagnosis as GERD. Patient outcomes and quality of life are greatly enhanced by suitable diagnostic techniques, appropriate therapy, interdisciplinary care, and comprehensive patient education along with frequent follow-ups.
Abstract: Achalasia results from the degeneration of inhibitory ganglion cells within the esophageal myenteric plexus and the lower esophageal sphincter (LES), leading to a loss of inhibitory neurons and resulting in the absence of peristalsis with failure of LES relaxation.
Background: Organ transplant is the procedure of replacing a failing or damaged organ with a functioning one. Positive attitude and awareness about donation are a must for donor organs to be available. This study explored the level of knowledge, perception and willingness regarding organ donation among medical students in Nepal.

Patients treated between January 2000 and December 2019 were classified according to the Von Laer classification, complications were classified according to the Sink classification and clinical outcomes were classified according to modified Flynn criteria. In total, 364 patients with a mean age of 5.

GI-ARS is characterized by compromised intestinal barrier integrity increasing the risk for infectious complications. Physiologically relevant animal models are crucial for elucidating host responses and therapeutic targets.

Carbon monoxide (CO), widely acknowledged as a toxic gas, is also known to provide unique therapeutic immune modulating effects. To facilitate delivery of CO, we have designed hyaluronic acid-based CO-gas-entrapping materials (CO-GEMs) for topical and prolonged gas delivery to the wound bed.

However, REBOA is associated with acute kidney injury (AKI) and subsequent mortality in severely injured trauma patients. Here, we investigated how the degree of aortic occlusion altered the extent of AKI in a porcine model.

Background There is an increasing life expectancy and a surging elderly population in the last few decades, leading to a higher incidence of fractures in the elderly. The health care of the elderly in Nepal is below par and there are no studies done to evaluate the spectrum of fractures in the elderly. Objective To evaluate the demographical and epidemiological aspects of fractures in the elderly (≥ 65 years) presenting to a tertiary care hospital in Nepal in a 15 years' timeline.

Ephedrine, metaraminol, epinephrine and maneuvers like carotid sinus stimulation used during intraoperative period have been postulated to cause temporary spasm of the coronary vessels leading to decrease supply to the myocardium and precipitating myocardial infraction in non-obstructive coronary arteries (MINOCA). As an anaesthesiologists, we should be aware that even a dose as small as 25 mcg epinephrine infiltrated along with local anaesthetic in the subcutaneous plane may be responsible for coronary vessel spasm and thus myocardial infraction in nonobstructive coronary arteries. We report a case of 45 years old female with papillary carcinoma of thyroid who developed features of non-ST elevation myocardial infarction 5 minutes after the subcutaneous infiltration of 5 ml of 2% Xylocaine with 1:200000 Epinephrine.

We identify a horizontally transferred T6SS with Ntox15 family nuclease effector (Tde1) that mediates interbacterial antagonism among Bacteroidales, including several derived from a single human donor. Expression of cognate (Tdi1) or orphan immunity proteins in acquired interbacterial defense systems protects against Tde1-dependent attack.
