The antigenic surface pattern of a continuous cell line (HT29) derived from a human primary carcinoma of the colon was studied by the immunofluorescence technique. Monovalent and polyvalent immune sera were used. The cells of this long-term culture kept the ability to synthesize the three principal colon tumor antigens: carcinoembryonic and nonspecific cross-reacting antigens, and the membrane-associated tissular autoantigen. On the HT29 cells, which still carry the original blood group of the tumor donor, no receptors for human Ig's were detected.

The recovery of valuable materials from spent lithium-ion batteries (LIBs) has experienced increasing demand in recent years. Current recycling technologies are typically energy-intensive and are often plagued by high operation costs, low processing efficiency, and environmental pollution concerns. In this study, an efficient and environmentally friendly dielectrophoresis (DEP)-based approach is proposed to separate the main components of "black mass" mixtures from LIBs, specifically lithium iron phosphate (LFP) and graphite, based on their polarizability differences.

Objective: The Supplemental Nutrition Assistance Program (SNAP) Online Purchasing Pilot (OPP) authorized the use of SNAP benefits online in Maryland in May 2020. We assessed shopping behavior and intentions associated with uptake and intended future use of online grocery shopping during and after COVID-19 among SNAP-eligible households.
Design: In this mixed-methods study, participants completed a survey on online grocery shopping, and a purposefully sampled subset participated in focus groups or in-depth interviews between November 2020 and March 2021.

Background: The WHO has highlighted that: "promotion of e-cigarettes has led to marked increases in e-cigarette use by children and adolescents." The long-term neuropsychiatric and psychological consequences of substance abuse in adolescence is well recognised. Limited data exists on the adolescent burden of vaping-related nicotine addiction and behavioural and/or psychological dependence to guide pharmacological or behavioural interventions to stop electronic cigarette usage.

The global probiotics market has been continuously growing, driven by consumer demand for immune-enhancing functional foods, dietary supplements, and natural therapeutics for gastrointestinal and gut function-mediated diseases. Probiotic microorganisms represent a diverse group of strains with complex but generalized mechanistic patterns. This review describes the various immunomodulatory mechanisms by which probiotics exert their effects, including the competitive exclusion of pathogenic microbes, production of antimicrobial substances, modulation of the immune system, and improvement of gut barrier function.
