Purpose: Neurogenic lower urinary tract dysfunction (NLUTD) is highly prevalent among patients with neurologic disorders. Some studies have demonstrated that implantable neuromodulation can improve symptoms of NLUTD. We seek to describe our experience with sacral and pudendal neuromodulation in patients with NLUTD.

Protection by natural cholera against later episodes of cholera over 10 years of follow-up in Matlab, Bangladesh: a retrospective cohort study.

Background: Patients with cholera have been shown to be protected against subsequent cholera for 3 years after their initial episode. We aimed to assess protection at 10 years of follow-up.

Methods: In this retrospective cohort study, cohorts of patients treated for cholera (index patients) and contemporaneously selected age-matched individuals without cholera (controls), randomly selected from the population of Matlab, Bangladesh, were assembled between 1990 and 2009 and followed for up to 10 years.

Evolution and ecology of anti-defence systems in phages and plasmids.

Prokaryotes (Bacteria and Archaea) encode a highly diversified arsenal of defence systems that protect them against mobile genetic elements, such as phages and plasmids. In turn, mobile genetic elements encode anti-defence systems that allow them to escape the activity of these defence systems. This has resulted in an evolutionary arms race in which defence systems and anti-defence systems evolve and adapt continuously, driving intriguing innovation and enormous diversification on both sides.

Dormancy: Metabolite pools prime the cyanobacterial dormancy-resuscitation switch.

Non-N-fixing cyanobacteria enter a state of dormancy when fixed nitrogen becomes limiting. Resuscitation from this state involves a complex program of events. A new study reveals how the dormancy-resuscitation switch is governed by metabolite-level control of glucose-6-phosphate dehydrogenase activity.

Dietary profiles of wild carnivores and Blastocystis occurrence: The case of the endangered Iberian lynx (Lynx pardinus) and systematic review.

Recent molecular and metagenomic studies have revealed that the obligate anaerobic protist Blastocystis is found more prevalently and with higher subtype diversities in herbivore species than in carnivore species. However, information on wild carnivore species is scarce. Here, we investigated the presence of Blastocystis by molecular methods in fecal DNA samples of free-ranging and captive Iberian lynxes from Spain (n = 243) and Portugal (n = 30).

Novel yeast Pichia kudriavzevii alleviates aflatoxins induced toxicopathology in broiler chickens through immunomodulation and antioxidant enhancement.

This study aimed to investigate the potential of Pichia kudriavzevii (PK), a newly discovered yeast strain, in alleviating the deleterious effects induced by aflatoxins on broilers. Eighty one-day-old broiler chicks were divided into four groups and subjected to various combinations of aflatoxin dosages at 300 μg/kg of feed alongside PK supplementation at 1 g/kg of feed. Assessment encompassed a comprehensive array of parameters including performance metrics, hepatic and renal biomarkers, interleukin concentrations, blood cell counts, hemoglobin concentration, packed cell volume, antibody response to sheep red blood cells, lymphoproliferative response to PHA-P, phagocytic response utilizing the carbon clearance assay system, as well as evaluation of oxidants and antioxidants.

A matched case-control study of porcine group A and C rotaviruses in a swine farrowing production system.

Group A rotaviruses (RVA) and group C rotaviruses (RVC) are important enteric pathogens in swine. Comprehensive studies investigating porcine rotaviruses in Canada are necessary to enhance understanding of the frequency, impacts, and dynamics of these infections in swine herds. This study aims to estimate the prevalence of RVA and RVC, describe circulating strains, and assess the association of rotaviruses with diarrhea at the piglet, litter, and batch levels in Canadian farrowing swine productions.

Triptolide alleviates allergic airway inflammation by inhibiting group 2 innate lymphoid cell function.

Group 2 innate lymphoid cells (ILC2s) produce the type 2 cytokines IL-5 and IL-13 and contribute to type 2 immune responses, such as allergic airway inflammation. However, specific drugs, especially traditional Chinese medicines, that target lung ILC2s have rarely been reported. Here, we demonstrate that triptolide ameliorates allergic airway inflammation by suppressing ILC2 activation.

Evaluation of anti-SARS-CoV-2 RBD antibody response after booster dose of SpikoGen® in individuals with two previous doses of Sinopharm and its association with HLA-DR and -DQ alleles.

Background: It has been demonstrated that COVID-19 vaccines confer significant protection, but temporal decay in the vaccine-induced antibodies has been reported; therefore, a third booster dose was considered. Human leukocyte antigen (HLA) class II molecules act as antigen presenting structures, play critical roles in the formation of an efficient antibody response. The current study aimed to evaluate the anti-receptor binding domain (RBD) antibody response after the booster dose of SpikoGen® vaccine in individuals with a history of Sinopharm primary vaccination series and its association with HLA-DQB1 and -DRB alleles.

Objective: To determine the positive predictive value (PPV) of CSF John Cunningham virus (JCV) quantitative PCR (qPCR) for progressive multifocal leukoencephalopathy (PML), and highlight neuroimaging findings reported to be suggestive of this disease.

Methods: We reviewed patients at London Health Sciences Centre with a positive CSF JCV qPCR result. Patients were classified as true-positive if they had a clinico-radiographic presentation compatible with PML and no more likely alternative diagnosis.

Lactobacillus salivarius metabolite succinate enhances chicken intestinal stem cell activities via the SUCNR1-mitochondria axis.

The activity of intestinal stem cells (ISCs) can be modulated by Lactobacillus, which subsequently affects the mucosal absorptive capacity. However, the underlying mechanisms remain unclear. In this study, a total of 189 Hy-Line Brown chickens (Gallus) were randomly assigned to one of seven experimental groups (n = 27 per group).

Schistosoma mattheei and zoonotic schistosomiasis.

We highlight the epidemiological importance of Schistosoma mattheei, a common parasite of livestock with an underappreciated ability to infect people, being recently incriminated in both female and male genital schistosomiasis. Through hybridisation(s) with other schistosome species, its public health importance will grow as its zoonotic potential expands across southern Africa.

Enterolactone combined with m6A Reader IGF2BP3 inhibits malignant angiogenesis and disease progression in ovarian cancer.

Background: Among all gynecological cancers, ovarian cancer is the leading cause of death. Epithelial ovarian cancer (EOC) accounts for over 85 % of ovarian cancer cases and is characterized by insidious onset, early metastasis, and a high recurrence rate. Alterations in gut microbiota, often as a consequence of chemotherapy, can promote cancer development and exacerbate the disease.

The Zika virus NS5 protein binds HSP90 to suppress EGF-induced Akt signaling and trophoblast cell migration.

Zika virus (ZIKV) infection during pregnancy can cause congenital Zika virus syndrome (CZV), including fetal growth restriction and death. In the developing placenta, trophoblast cells respond to epidermal growth factor (EGF) to migrate into the decidua to facilitate implantation and fetal development. EGF activates the Akt protein kinase, a master regulator of trophoblast cell migration.

Sex differences in dorsal striatal volume and interest in quitting smoking.

Aims: Over the recent decades, smoking among women has become an increasingly pressing public health challenge. Mounting evidence suggests that, compared to men, women's smoking is more strongly influenced by habitual responses to sensorimotor cues. To understand the brain mechanisms underlying the cessation challenges commonly reported by women who smoke, the present study used voxel-based morphometry (VBM) to investigate sex-related volumetric differences in the dorsal striatum, a region implicated in habitual substance use behavior, and their associations with self-reported quit interest among daily smoking adults.

Nitroxoline evidence amoebicidal activity against Acanthamoeba castellanii through DNA damage and the stress response pathways.

Acanthamoeba castellanii is a widespread unicellular eukaryote found in diverse environments, including tap water, soil, and swimming pools. It is responsible for severe infections, such as Acanthamoeba keratitis and granulomatous amebic encephalitis, particularly in individuals with immunocompromisation. The ability of protozoans to form dormant and persistent cysts complicates treatment, as current therapies are ineffective against cyst stages and suffer from poor specificity and side effects.
