The type VI secretion system (T6SS) is a sophisticated, contact-dependent nanomachine involved in interbacterial competition. To function effectively, the T6SS must penetrate the membranes of both attacker and target bacteria. Structures associated with the cell envelope, like polysaccharides chains, can therefore introduce spatial separation and steric hindrance, potentially affecting the efficacy of the T6SS.

Article Synopsis
  • - The study highlights the potential of activating the neurokinin 2 receptor (NK2R) as a dual approach to combat obesity and type 2 diabetes by suppressing appetite and increasing energy expenditure, representing a significant advancement over current multi-drug strategies.
  • - Researchers developed long-acting NK2R agonists that can be administered weekly, which showed promising results in mice, leading to weight loss and improved insulin sensitivity without relying on traditional leptin signaling.
  • - In tests with diabetic, obese macaques, NK2R activation resulted in substantial reductions in body weight, blood glucose, and cholesterol levels, suggesting a single-target therapeutic option that enhances energy balance and addresses cardiometabolic issues across different species.

Current antiretroviral therapy (ART) regimens efficiently limit HIV replication, thereby improving the life expectancy of people living with HIV; however, they also cause metabolic side effects. The ongoing obesity epidemic has resulted in more people with metabolic comorbidities at the time of HIV infection, yet the effect of preexisting metabolic dysregulation on infection sequelae and response to ART is unclear. Here, to investigate the impact of preexisting obesity and insulin resistance on acute infection and subsequent long-term ART, we infected a cohort of lean and obese adult male macaques with SIV and administered ART.

Article Synopsis
  • Three different strategies exist for starting warfarin: fixed dosing (FWD), clinical dosing (CWD), and genetic-guided dosing (GWD), with GWD shown to be superior in some trials.
  • In a study comparing CWD and FWD, researchers found no significant difference in time spent within the therapeutic range or in extreme INR levels between the two methods.
  • The conclusion is that CWD did not provide better anticoagulation quality compared to FWD, suggesting that fixed dosing may continue to be a viable option.

Objectives: We investigated the feasibility of replacing face-to-face with telephone interviews conducted as part of the World Mental Health Qatar (WMHQ) survey and discuss the main methodological changes across the two pilots that were subsequently implemented in the full-scale WMHQ telephone survey.

Methods: We assessed the net mode effect by comparing the lifetime prevalence estimates of the main mental disorder classes (mood and anxiety disorders) and a number of disorders across the two survey pilots conducted prior to and post-pandemic.

Results: The main differences in terms of methodology for both pilots stemmed from differences in the survey mode, including questionnaire length, study recruitment method, and fielding team size and structure.

The zebrafish (Danio rerio) is an important model organism for basic as well as applied bio-medical research. One main advantage is its genetic tractability, which was greatly enhanced by the introduction of the CRISPR/Cas method a decade ago. The generation of loss-of-function alleles via the production of small insertions or deletions in the coding sequences of genes with CRISPR/Cas systems is now routinely achieved with high efficiency.

is a pathogen that causes disease in millions of people every year by colonizing the small intestine and then secreting the potent cholera toxin. How the pathogen overcomes the colonization barrier created by the host's natural microbiota is, however, still not well understood. In this context, the type VI secretion system (T6SS) has gained considerable attention given its ability to mediate interbacterial killing.

Article Synopsis
  • - Warfarin, a blood thinner, is heavily processed by the enzyme CYP2C9, and using it alongside rifampin, which boosts CYP2C9 activity, requires careful monitoring and dosage changes due to variable responses in patients.
  • - A study from 2016 to 2022 at Hamad Medical Corporation identified 36 patients using both medications, finding that those with certain genetic variants of CYP2C9 and VKORC1 were more likely to respond effectively to warfarin.
  • - Patients with these beneficial genotypes had a lower pre-interaction warfarin dose and better anticoagulation control compared to those without, indicating that genetic factors play a crucial role in treatment responses when taking warfar

Bacteria represent a class of living cells that are very attractive carriers for the transport and delivery of nano- and microsized particles. The use of cell-based carriers, such as for example bacteria, may allow to precisely direct nano- or microsized cargo to a desired site, which would greatly enhance the selectivity of drug delivery and allow to mitigate side effects. One key step towards the use of such nano-/microparticle - bacteria hybrids is the immobilization of the cargo on the bacterial cell surface.

Introduction: One-third of patients have clopidogrel resistance that may lead to major adverse cardiac events (MACEs). By contrast, it was found that some clopidogrel-treated patients have hyperresponsive platelets that are associated with higher bleeding risk. Several studies have shown that polymorphisms in the gene encoding the CYP2C19 contribute to the variability in response to clopidogrel.
