Orally administered probiotics encounter various challenges on their journey through the mouth, stomach, intestine and colon. The health benefits of probiotics are diminished mainly due to the substantial reduction of viable probiotic bacteria under the harsh conditions in the gastrointestinal tract and the colonization resistance caused by commensal bacteria. In this review, we illustrate the factors affecting probiotic viability and their mucoadhesive properties through their journey in the gastrointestinal tract, including a discussion on various mucosadhesion-related proteins on the probiotic cell surface which facilitate colonization.

Gut IgA-antibody secreting cells segregate into four Blimp1+ subsets based on differential expression of IgA and Ki-67 and are retained following prolonged αCD20 B cell depletion in mice.

B cell depletion is an efficacious therapy for multiple sclerosis, but its long-term safety profile in the gastrointestinal tract has not been specifically studied. This is of importance because the gut is the largest reservoir of IgA in the body, which maintains gut homeostasis in part by regulating the composition of the gut microbiota. This was addressed by development of a prolonged B cell depletion model using human CD20 transgenic mice and B cell depletion with the anti-human CD20 antibodies rituximab, a humanized mouse monoclonal, and 2H7, the mouse precursor to ocrelizumab.

Purpose: There is no consensus on the standard approach for trans-sphincteric perianal fistulas (TPAF) in the elderly population. The most commonly used sphincter-saving procedures are ligation of the inter-sphincteric fistula tract (LIFT) and mucosal advancement flap (MAF). We aimed to evaluate the incidence and risk factors for recurrence and incontinence in elderly patients with TPAF using both approaches.

The aim was to assess the correlation between periodontal status, whole salivary interleukin-1 beta (IL-1β) levels and oral yeasts carriage (OYC) among individuals with varying ranges of body mass index (BMI). Material and method: The weight, waist circumference (WC), and height of individuals were assessed. Participants were categorized into three groups: Group-1 - normal weight (18.
