A Pilot Open-Label Randomized Study to Evaluate the Safety, Tolerability, and Acceptability of the IntegriMedical® Needle Free Injection System versus a Conventional Needle-Based System in Healthy Volunteers, Using Normal Saline as a Placebo.

Purpose: The study aimed to assess the safety, tolerability, and acceptability of the IntegriMedical® Needle Free Injection System (IM-NFIS) compared to conventional hypodermic needle injections (CHN) in healthy adult subjects across multiple injection sites.

Patients And Methods: Thirty healthy male subjects aged 18-45 years were enrolled in this open-label study. Each subject received both NF and CHN injections at five different sites (forearm, abdomen, thigh, buttocks, and arm).

Post-Acute Sequelae of Covid-19: A System-wise Approach on the Effects of Long-Covid-19.

The SARS-CoV-2 virus responsible for the COVID-19 pandemic has profoundly impacted global health, economics, and society. This review seeks to encompass an overview of current knowledge on COVID-19, including its transmission, pathogenesis, and clinical presentation related to various systems within the human body. COVID-19 is a highly contagious illness that has rapidly spread worldwide.

Immune-mediated Bowel Disease: Role of Intestinal Parasites and Gut Microbiome.

Immune-mediated bowel diseases (IMBD), notably ulcerative colitis and Crohn's disease, impose a substantial global health burden due to their intricate etiology and escalating prevalence. The nexus between intestinal parasites and the gut microbiome in IMBD is a dynamic and complex field of study. Several studies have evidenced the capacity of intestinal parasites to modulate the gut microbiome, inducing alterations in microbial diversity, abundance, and metabolic activity.

Fourth Ventricular Rosai-Dorfman Disease Mimicking Intraventricular Tumor in Young Adult: A Rare Case Report.

Rosai-Dorfman disease (RDD) or sinus histiocytosis with massive lymphadenopathy can present with or without systemic disease. It is a benign histioproliferative disorder characterized by generalized lymphadenopathy, weakness, anemia, and rarely extranodal involvement. While RDD most commonly affects lymph nodes, extranodal involvement of multiple organs has been reported, including the central nervous system (CNS).

IS-mediated chromosomal amplification of the operon leads to polymyxin B resistance in B strains.

Polymyxins [colistin and polymyxin B (PMB)] comprise an important class of natural product lipopeptide antibiotics used to treat multidrug-resistant Gram-negative bacterial infections. These positively charged lipopeptides interact with lipopolysaccharide (LPS) located in the outer membrane and disrupt the permeability barrier, leading to increased uptake and bacterial cell death. Many bacteria counter polymyxins by upregulating genes involved in the biosynthesis and transfer of amine-containing moieties to increase positively charged residues on LPS.
