Impact of Repeated Variant Exposures on Cellular and Humoral Immunogenicity Induced by SARS-CoV-2 Vaccines.

Background/objectives: The emergence of the Omicron variant has complicated COVID-19 control and prompted vaccine updates. Recent studies have shown that a fourth dose significantly protects against infection and severe disease, though long-term immunity data remain limited. This study aimed to assess Anti-S-RBD antibodies and interferon-γ levels in healthcare workers 12 months after receiving bivalent Original/Omicron BA.

Increased expression levels of PIEZO1 in visceral adipose tissue in obesity and type 2 diabetes are triggered by mechanical forces and are associated with inflammation.

Background: PIEZO1 has emerged as a mechanoreceptor linked with adipogenesis, adipose tissue (AT) inflammation and insulin resistance. We aimed to determine the impact of obesity and obesity-associated type 2 diabetes (T2D) as well as mechanical compression forces on the expression of PIEZO1 in visceral AT (VAT) and its relation with inflammation.

Methods: Blood and VAT samples were obtained from 100 volunteers.

Transmission Rates of UV-A and Green Light in an ex vivo Corneal Cross-linking Model for Infectious Keratitis.

Purpose: To investigate the light transmission (LT) of UV-A and green light through infected corneas saturated with riboflavin or rose bengal in an ex vivo porcine model for infectious keratitis.

Setting: University of Zurich and EMPA.

Design: Laboratory study.

Internal hernia after trans-abdominal preperitoneal (TAPP) hernia repair: A case report.

Introduction: Hernia repair is a common procedure performed by general surgeons. Introduced in 1990s, the use of laparoscopic hernia repair has recently increased and, consequently, rare complications previously unknown have been reported.

Presentation Of Case: A 43-years-old male patient who underwent a transabdominal preperitoneal patch plasty (TAPP) procedure for symptomatic bilateral inguinal hernia.
