Composition-dependent pore structure and filtration performance of hydrogel-filled membranes.

Microfiltration (MF) membranes reject large-sized solutes (>0.1 μm) from feed streams. Filling up the MF pore space with porous polymers tailor solute rejection by virtue of membrane structure alterations.

A Rare Presentation of Juvenile Rectal Polyps in an Adolescent Male With Rectal Bleeding: A Case Report.

Juvenile rectal polyps are hamartomatous growths commonly occurring in the colon and rectum, characterized by cystic dilation of glandular structures within the lamina propria. They are typically under 10 years of age, but may also be seen in adolescents. This case report describes a 13-year-old boy with a five-year history of difficulty in defecation, intermittent rectal bleeding that progressively worsened over the past year, along with abdominal pain and prolapse of a rectal mass.

Developing multifunctional zwitterionic-xanthan gum-anchored network copolymers for biomedical applications.

Herein, mucoadhesive and biocompatible network hydrogels were developed by grafting zwitterionic polymer poly(2-[(methacryoyloxy)ethyl]dimethyl (3-sulfopropyl) ammonium hydroxide (poly(MEDSAH)) onto bacterial-derived polysaccharide xanthan gum (XG) free radical graft polymerization, followed by crosslinking with ,'-methylene bisacrylamide (NNMBA). The developed polymeric hydrogels were characterized using XRD, FTIR, C-NMR, TGA-DSC, FESEM, EDX and AFM analyses. FESEM and AFM analyses of these hydrogels demonstrated morphological heterogeneous features with surface roughness.

A spinal arachnoid cyst is a rare entity representing only 1 to 3% of spinal canal lesions. Very few of them are reported to be symptomatic. Moreover, occurrence in multiples is even rarer.

Outbreak investigation of acute febrile illness from the Himalayan foothills: Solving the puzzle of fever.

In September 2022, Panchkula Civil Hospital reported an outbreak of acute febrile illness (AFI) in Pinjore, located in the Himalayan foothills, Haryana, North India. There was an upsurge of fever cases. Blood samples were taken from suspected patients ( = 58) with AFI and subjected to serology of dengue, chikungunya, Japanese encephalitis, and scrub typhus.

Molecular detection of dengue and chikungunya viruses in surveillance of wild-caught Aedes mosquitoes in Punjab, North India.

Background: Dengue (DENV), Zika (ZIKV) and chikungunya (CHIKV) viruses are transmitted mainly by Aedes mosquitoes and are responsible for a significant global healthcare burden. The current study aimed to detect arboviruses in the Aedes mosquitoes in close proximity of patients during the transmission season.

Methods: Both immature and adult mosquitoes were collected from in and around the patients' houses.

Hepatitis B virus-induced hepatocellular carcinoma: a persistent global problem.

Hepatitis B virus (HBV) infections are highly prevalent globally, representing a serious public health problem. The diverse modes of transmission and the burden of the chronic carrier population pose challenges to the effective management of HBV. Vaccination is the most effective preventive measure available in the current scenario.

Victims of armed conflict in India: psychosocial impact and available support.

India has been a part of 5 major wars since its independence in 1947 and hosts over 212,413 refugees from Sri Lanka, Tibet and Bangladesh. So, a wide spectrum of trauma survivors, both civilian and military, live in this country and require mental healthcare. We discuss the psychological impact of armed conflict and how the country and culture tint it uniquely.

A Prospective Correlation Study Between Computerized Tomography of Paranasal Sinuses and Nasal Endoscopy Findings in Patients of Chronic Rhinosinusitis Undergoing Functional Endoscopic Sinus Surgery.

In order to diagnose chronic rhinosinusitis (CRS), diagnostic nasal endoscopy (DNE) and computed tomography (CT) scan both are important investigations. But both have their pros and cons, some findings are seen better in DNE and others in CT. Our study aims to correlate DNE and CT findings.

Handmade models for aneurysm surgery: A useful tool for training.

Background: Aneurysm surgery is considered difficult by young and trainee neurosurgeons. This is due to difficulty in understanding orientation of aneurysm complex (proximal and distal vessels, aneurysm neck, and fundus) in relation to the surrounding structures (skull, brain, vessels, and nerves) after head is rotated, extended, and fixed on the head frame. Virtual three-dimensional (3D) imaging studies and 3D-printed models help young neurosurgeons but are not accessible to most of the centers due to need for resources (human and equipment).

OGAS: Omni-directional Glider Assisted Scheme for autonomous deployment of sensor nodes in open area wireless sensor network.

Wireless Sensor Network (WSN) is built with the wireless interconnection of Sensor Nodes (SNs) generally deployed to monitor the changes within the environment of hostile, rugged, and unreachable target regions. The optimal placement of SNs is very important for the efficient and effective operation of any WSN. Unlike small and reachable regions, the deployment of the SNs in large-scale regions (e.
