Treatment Options and the Management of Complications in Hydatid Cysts of the Liver in Endemic Regions
CONCLUSION: Surgical treatment should represent the standard procedure since it is safe and effective, ensures complete elimination of the parasite, involves no intraoperative shedding, preserves healthy tissues, and minimizes the risk of long-term recurrence and cavity-related complications.PMID:38684490 | DOI:10.62713/aic.3379 (Source: Annali Italiani di Chirurgia)

Probiotics: Shaping the gut immunological responses
World J Gastroenterol. 2024 Apr 21;30(15):2096-2108. doi: 10.3748/wjg.v30.i15.2096.ABSTRACTProbiotics are live microorganisms exerting beneficial effects on the host's health when administered in adequate amounts. Among the most popular and adequately studied probiotics are bacteria from the families Lactobacillaceae, Bifidobacteriaceae and yeasts. Most of them have been shown, both in vitro and in vivo studies of intestinal inflammation models, to provide favorable results by means of improving the gut microbiota composition, promoting the wound healing process and shaping the immunological responses. Chronic intestinal c...

Autologous platelet-rich plasma for assisted reproduction
CONCLUSIONS: We are uncertain about the effect of intrauterine or intraovarian administration of PRP on outcomes of assisted reproduction technology in infertile women. The pooled results should be interpreted with caution. Only one of the 12 included studies was judged at low risk of bias. Other limitations of the included trials were failure to report live birth, poor reporting of methods, lack of prospective protocol registration, low precision due to the small number of enrolled participants, indirectness due to the specific subpopulations and settings studied, and insufficient or absent safety data.PMID:38682756 | PMC...

Antinuclear antibody titration and pattern are helpful in the diagnosis of systemic autoimmune rheumatic diseases
CONCLUSION: ANA-IIF titration of equal or more than 1:320 can be used as the best titration for differentiating between SARDs and non-SARDs in a positive ANA sample. Patients with homogeneous pattern were more likely to be diagnosed with SARDs than other ANA-IIF patterns.PMID:38682845 (Source: Malaysian Journal of Pathology)

A Significant Contribution of the Classical Pathway of Complement in SARS-CoV-2 Neutralization of Convalescent and Vaccinee Sera
In this study, we report that the SARS-CoV-2 neutralization titers of human convalescent sera were relatively consistent across all disease states except for severe COVID-19, which yielded significantly higher neutralization titers. Furthermore, we show that heat inactivation of human serum significantly lowered neutralization activity in a live virus SARS-CoV-2 neutralization assay. Heat inactivation of human convalescent serum was shown to inactivate complement proteins, and the contribution of complement in SARS-CoV-2 neutralization was often >50% of the neutralizing activity of human sera without heat inactivation a...

BHLHE40 Regulates Myeloid Cell Polarization through IL-10-Dependent and -Independent Mechanisms
In this study, we report that BHLHE40 is required in myeloid cells exposed to GM-CSF, an abundant cytokine in the lung, to promote the expression of genes associated with a proinflammatory state and better control of M. tuberculosis infection. Loss of Bhlhe40 expression in murine bone marrow-derived myeloid cells cultured in the presence of GM-CSF results in lower levels of proinflammatory associated signaling molecules IL-1β, IL-6, IL-12, TNF-α, inducible NO synthase, IL-2, KC, and RANTES, as well as higher levels of the anti-inflammatory-associated molecules MCP-1 and IL-10 following exposure to heat-killed M. tubercul...

Polyclonally Derived Alloantigen-Specific T Regulatory Cells Exhibit Target-Specific Suppression and Capture MHC Class II from Dendritic Cells
J Immunol. 2024 Apr 29:ji2300780. doi: 10.4049/jimmunol.2300780. Online ahead of print.ABSTRACTFoxp3+ T regulatory (Treg) cells prevent allograft rejection and graft-versus-host disease. Although polyclonal Tregs have been used both in animal models and in humans, the fine specificity of their suppressive function is poorly defined. We have generated mouse recipient-derived alloantigen-specific Tregs in vitro and explored the fine specificity of their suppressive function and their mechanism of action in vitro and in vivo. In vitro, when alloantigen and peptide Ag were both presented on the same dendritic cell, both respon...

Tissue-specific features of innate lymphoid cells in antiviral defense
Cell Mol Immunol. 2024 Apr 29. doi: 10.1038/s41423-024-01161-x. Online ahead of print.ABSTRACTInnate lymphocytes (ILCs) rapidly respond to and protect against invading pathogens and cancer. ILCs include natural killer (NK) cells, ILC1s, ILC2s, ILC3s, and lymphoid tissue inducer (LTi) cells and include type I, type II, and type III immune cells. While NK cells have been well recognized for their role in antiviral immunity, other ILC subtypes are emerging as players in antiviral defense. Each ILC subset has specialized functions that uniquely impact the antiviral immunity and health of the host depending on the tissue microe...

Potent Immunomodulators Developed from an Unstable Bacterial Metabolite of Vitamin B2 Biosynthesis
We report their water stability, capacity to bind MR1 and traffic it to the cell surface (EC50 17 nM), potent activation (EC50 56 pM) or inhibition (IC50 80 nM) of interacting MAIT cells, and develop compounds with diazirine-alkyne, biotin, or fluorophore labels for studying cellular MR1. Computer modelling casts new light on the molecular mechanism of activation, revealing that activators are first captured in MR1 via pi-interactions and H-bonds, before tighter covalent bonding to Lys43 in MR1. This chemical study advances our molecular understanding of how bacterial metabolites are captured by MR1, influence cell surface...

Effect of dietary supplementation of plantain herb, lemongrass and their combination on milk yield, immunity, liver enzymes, serum, and milk mineral status in dairy cows
CONCLUSIONS: Both plantain and lemongrass improved dairy cows' DM consumption and milk yield. Plantain and/or lemongrass enhanced the immune system and liver health, but not serum and milk calcium and phosphorus level. Lemongrass and a combination of plantain and lemongrass increased the serum and milk zinc concentrations.PMID:38680813 | PMC:PMC11055577 | DOI:10.5455/javar.2024.k764 (Source: Adv Data)

The two faces of antibiotics: an overview of the effects of antibiotic residues in foodstuffs
Arch Toxicol. 2024 Apr 30. doi: 10.1007/s00204-024-03760-z. Online ahead of print.ABSTRACTAntibiotics, which have been used for many years to treat infections, also play an important role in food contamination with antibiotic residues. There is also unnecessary use of antibiotics, particularly to increase production efficiency. Non-compliance with withdrawal periods and maximum residue limits (MRLs) for antibiotics used in food-producing animals results in undesirable events, such as allergic reactions, teratogenicity, carcinogenicity, changes in the microbiota and, in particular, antibiotic resistance. Therefore, it may b...
