Immunostimulatory effects of isomalto/malto-polysaccharides via TLR2 and TLR4 in preventing doxycycline-induced cytokine loss.

Isomalto/malto-polysaccharides (IMMPs) are α-glucans with prebiotic potential used as food ingredients. However, their ability to exert direct cellular effects remains unknown. IMMPs may enhance immunity by activating toll-like receptors (TLRs), key for defense against pathogens.

Exopolysaccharides from Bifidobacterium longum subsp. infantis and Bifidobacterium adolescentis modulate Toll-like receptor signaling.

Background: Exopolysaccharides (EPS) from probiotic bacteria like bifidobacteria, have gained considerable attention for the beneficial effects they exert in the gastrointestinal environment. Here, we investigated whether EPS isolated from Bifidobacterium longum subsp. infantis and Bifidobacterium adolescentis can interact with Toll-like receptors (TLRs) in a structure-dependent way and subsequently we investigated whether they influence cytokine-production in dendritic cells (DCs).

Prebiotics in food and dietary supplements: a roadmap to EU health claims.

Numerous studies have established that prebiotic ingredients in foods and dietary supplements may play a role in supporting human health. Over the three decades that have passed since prebiotics were first defined as a concept, research has revealed a complex universe of prebiotic-induced changes to the human microbiota. There are strong indications of a direct link between these prebiotic-induced changes and specific health benefits.

Perspectives of Patients and Clinicians on Reproductive Health Care and ADPKD.

Introduction: Family planning and reproductive care are essential but complex aspects of lifecycle management for individuals with autosomal dominant polycystic kidney disease (ADPKD), given the potential genetic transmission and pregnancy-related complications. In this qualitative study, we studied the experiences and perspectives of patients with ADPKD and clinicians to identify areas for potential improvement in reproductive lifecycle care.

Methods: Focus group discussions (FGDs) were conducted in the Netherlands with patients with ADPKD, both men and women, who had children through varied reproductive choices; and clinicians, including (pediatric) nephrologists, obstetric gynecologists and geneticists.

The effect of nerve cells on the intestinal barrier function and the influence of human milk oligosaccharides (hMOs) on the intestinal neuro-epithelial crosstalk.

The intestinal epithelium is an important gatekeeper of the human body by forming a barrier for the luminal content of the intestine. The barrier function is regulated by a complex crosstalk between different cell types, including cells from the enteric nervous system (ENS). ENS is considered to influence gastrointestinal processes and functions, but its direct effect on epithelial barrier function remains to be confirmed.

Post-traumatic parkinsonism: The intricate twist between trauma, inflammation and neurodegeneration. A narrative review.

Post-traumatic Parkinsonism (PTP) is a complex neurological disorder that is often associated with the occurrence of a traumatic brain injury (TBI). PTP can occur either in the acute or chronic phase of TBI. There is still uncertainty about the mechanisms provoking PTP, which can be the result of the acute blast itself or secondary neurodegenerative process occurring months to years post the acute trauma.

Oncologists' communication about tobacco and alcohol use during treatment for esophagogastric cancer: a qualitative observational study of simulated consultations.

Purpose: Tobacco and alcohol use influence cancer risk as well as treatment outcomes, specifically for esophageal and gastric cancer patients. Therefore, it is an important topic to discuss during consultations. This study aims to uncover medical, radiation, and surgical oncologists' communication about substance use, i.

Hyperactive Nickase Activity Improves Adenine Base Editing.

Base editing technologies enable programmable single-nucleotide changes in target DNA without double-stranded DNA breaks. Adenine base editors (ABEs) allow precise conversion of adenine (A) to guanine (G). However, limited availability of optimized deaminases as well as their variable efficiencies across different target sequences can limit the ability of ABEs to achieve effective adenine editing.

Harnessing cellular therapeutics for type 1 diabetes mellitus: progress, challenges, and the road ahead.

Type 1 diabetes mellitus (T1DM) is a growing global health concern that affects approximately 8.5 million individuals worldwide. T1DM is characterized by an autoimmune destruction of pancreatic β cells, leading to a disruption in glucose homeostasis.

Pancreatic stellate cells support human pancreatic β-cell viability and enhance survival of immunoisolated human islets exposed to cytokines.

Pancreatic islet transplantation is proposed as a cure for type 1 diabetes mellitus (T1D). Despite its success in optimal regulation of glucose levels, limitations in longevity of islet grafts still require innovative solutions. Inflammatory stress post-transplantation and loss of extracellular matrix attribute to the limited β-cell survival.

Quality of life improvement from thoracoscopic atrial fibrillation ablation in women versus men: a prospective cohort study.

Objectives: Thoracoscopic ablation has proven to be an effective and safe rhythm control strategy, especially for persistent atrial fibrillation. However, its impact on quality of life (QoL) and potential gender differences remains unclear.

Methods: This prospective, single-centre observational study included consecutive patients with symptomatic atrial fibrillation undergoing thoracoscopic ablation.

Sustainable diets with plant-based proteins require considerations for prevention of proteolytic fermentation.

The human diet requires a more plant-based approach due to the exhaustive effects animal-based foods have on the environment. However, plant-based proteins generally miss a few or have a lower variety in essential amino acids and are more difficult to digest. Subsequently they might be prone to fermentation by the microbiome in the proximal colon.

"Modeling Diffusive Search by Non-Adaptive Sperm: Empirical and Computational Insights".

Unlabelled: During fertilization, mammalian sperm undergo a winnowing selection process that reduces the candidate pool of potential fertilizers from ∼10 -10 cells to 10 -10 cells (depending on the species). Classical sperm competition theory addresses the positive or 'stabilizing' selection acting on sperm phenotypes within populations of organisms but does not strictly address the developmental consequences of sperm traits among individual organisms that are under purifying selection during fertilization. It is the latter that is of utmost concern for improving assisted reproductive technologies (ART) because 'low fitness' sperm may be inadvertently used for fertilization during interventions that rely heavily on artificial sperm selection, such as intracytoplasmic sperm injection (ICSI).

Acacia fiber or probiotic supplements to relieve gastrointestinal complaints in patients with constipation-predominant IBS: a 4-week randomized double-blinded placebo-controlled intervention trial.

Purpose: To date, no adequate treatment for irritable bowel syndrome with predominant constipation complaints (IBS-C) is available. Fibers with prebiotic properties and probiotic compounds have shown promise in relieving IBS-C-related complaints. We aimed to determine the effects of a 4-week intervention with either an Acacia fiber (AF) with prebiotic properties or a probiotic Bifidobacterium Lactis (BLa80) supplement, compared to a control supplement, on stool pattern, IBS symptoms and Quality of Life (QoL), in IBS-C individuals.

Mutational rescue of the activity of high-fidelity Cas9 enzymes.

Programmable DNA endonucleases derived from bacterial genetic defense systems, exemplified by CRISPR-Cas9, have made it significantly easier to perform genomic modifications in living cells. However, unprogrammed, off-target modifications can have serious consequences, as they often disrupt the function or regulation of non-targeted genes and compromise the safety of therapeutic gene editing applications. High-fidelity mutants of Cas9 have been established to enable more accurate gene editing, but these are typically less efficient.

Association between days post-conception and lactation persistency in dairy cattle.

Determining the optimal insemination moment for individual cows is complex, particularly when considering the effects of pregnancy on milk production. The effect of pregnancy on the absolute milk yield has already been reported in several studies. Currently, there is limited quantitative knowledge about the association between days post-conception (DPC) and lactation persistency, based on a lactation curve model, and, specifically, how persistency changes during pregnancy and relates to the days in milk at conception (DIMc).

Exopolysaccharide β-(2,6)-levan-type fructans have a molecular-weight-dependent modulatory effect on Toll-like receptor signalling.

Scope: Fructans are a group of dietary fibers which are known to have many beneficial effects including immune-modulating effects. A family of fructans are β-(2,6)-linked levan-type fructans that are known to serve as exopolysaccharides in the cell wall of many species of bacteria including commensal bacteria and probiotics. It is still largely unknown whether and how they can serve as immunomodulating molecules.
