Microbiome metabolic capacity is buffered against phylotype losses by functional redundancy.

Unlabelled: Many animals contain a species-rich and diverse gut microbiota that likely contributes to several host-supportive services that include diet processing and nutrient provisioning. Loss of microbiome taxa and their associated metabolic functions as result of perturbations may result in loss of microbiome-level services and reduction of metabolic capacity. If metabolic functions are shared by multiple taxa (i.

is one of the closest relatives of the highly host-adapted and uncultivable hemotrophic mycoplasma. The complete genome of strain 117C was constructed from long-reads derived from Pacific Biosciences single-molecule, real-time sequencing technology. The genome is organized into one circular, gapless chromosome with a length of 1,034 kb.

Myristoylated Neuronal Calcium Sensor-1 captures the ciliary vesicle at distal appendages.

The primary cilium is a microtubule-based organelle that cycles through assembly and disassembly. In many cell types, formation of the cilium is initiated by recruitment of ciliary vesicles to the distal appendage of the mother centriole. However, the distal appendage mechanism that directly captures ciliary vesicles is yet to be identified.

Influence of sewage effluent discharge on putative pathogen community in drinking water sources: insights from full-length 16S rRNA gene amplicon sequencing.

The discharge of sewage effluent is a major source of microbial contamination in drinking water sources, necessitating a comprehensive investigation of its impact on pathogenic bacterial communities. This study utilized full-length 16S rRNA gene amplicon sequencing to identify putative pathogenic bacteria and analyze their community structures in drinking water sources subjected to different levels of fecal pollution: urban rivers with low, moderate, and high sewage effluent mixing ratios, and mountain streams with minimal human impact. The sewage effluent itself was also analyzed.

Wastewater microbiology: occurrence and prevalence of antibiotic-resistant extended-spectrum -lactamase-producing Enterobacteriaceae in the district wastewater system.

Extended spectrum -lactamase (ESBL)-producing Enterobacteriaceae, including and , pose a serious risk to human health because of antibiotic resistance. Wastewater serves as a reservoir for these bacteria, contributing to the evolution and transmission of antibiotic-resistant strains. The research aims to identify ESBL bacterium in wastewater samples from District Kohat.

Synaptic enrichment and dynamic regulation of the two opposing dopamine receptors within the same neurons.

Dopamine can play opposing physiological roles depending on the receptor subtype. In the fruit fly , and encode the D- and D-like receptors, respectively, and are reported to oppositely regulate intracellular cAMP levels. Here, we profiled the expression and subcellular localization of endogenous Dop1R1 and Dop2R in specific cell types in the mushroom body circuit.

A hierarchical pathway for assembly of the distal appendages that organize primary cilia.

Distal appendages are nine-fold symmetric blade-like structures attached to the distal end of the mother centriole. These structures are critical for formation of the primary cilium, by regulating at least four critical steps: ciliary vesicle recruitment, recruitment and initiation of intraflagellar transport (IFT), and removal of CP110. While specific proteins that localize to the distal appendages have been identified, how exactly each protein functions to achieve the multiple roles of the distal appendages is poorly understood.

Wildfire Smoke Contributions to Polycyclic Aromatic Hydrocarbon Loadings in Western Canadian Urban Surface Grime.

Wildfires emit large amounts of polycyclic aromatic hydrocarbons (PAHs) into the atmosphere. As PAHs emitted from anthropogenic sources are known to accumulate in urban surface grime present on building exteriors and windows, we hypothesized that PAH-containing wildfire smoke plumes could similarly increase PAH grime loadings. To explore this hypothesis, we coupled analysis of PAHs in grime samples collected from August to November 2021 in two historically smoke-affected Canadian cities, Calgary and Kamloops, with contemporaneous field- and model-based indicators of wildfire influence.

Proximity proteomics provides a new resource for exploring the function of Afadin and the complexity of cell-cell adherens junctions.

The network of proteins at the interface between cell-cell adherens junctions and the actomyosin cytoskeleton provides robust yet dynamic connections that facilitate cell shape change and motility. While this was initially thought to be a simple linear connection via classic cadherins and their associated catenins, we now have come to appreciate that many more proteins are involved, providing robustness and mechanosensitivity. Defining the full set of proteins in this network remains a key objective in our field.

Parsing reward sensitivity reveals distinct relationships with energy intake, metabolic markers, physical activity and fitness.

Rewards are rewarding owing to their hedonic or metabolic value. Individual differences in sensitivity to rewards are predictive of mental health problems but may reflect variation in metabolic types. We have assessed the association of two distinguishable aspects of reward sensitivity, openness to rewards (the striving towards multiple rewards) and insatiability by reward (the strong pursuit and fixation to a particular reward), with measures of metabolism and activity in a longitudinal study of representative birth cohort samples.

Is this scenery worth exploring? Insight into the visual encoding of navigating ants.

Solitary foraging insects like desert ants rely heavily on vision for navigation. While ants can learn visual scenes, it is unclear what cues they use to decide if a scene is worth exploring at the first place. To investigate this, we recorded the motor behavior of Cataglyphis velox ants navigating in a virtual reality set-up (VR) and measured their lateral oscillations in response to various unfamiliar visual scenes under both closed-loop and open-loop conditions.

Evolutionary insights into gut acidification: Invertebrate-like mechanisms in the basal vertebrate hagfish.

Acidification is a key component of digestion throughout metazoans. The gut digestive fluid of many invertebrates is acidified by the vesicular-type H+-ATPase (VHA). In contrast, vertebrates generate acidic gut fluids using the gastric H+/K+-ATPase (HKA); an evolutionary innovation linked with the appearance of a true stomach that greatly improves digestion, absorption, and immune function.

An Assessment of the Nutritional Profile of Foods Accessible to Incarcerated Males in Alabama.

Many chronic medical conditions that can result from poor nutrition are more prevalent in the incarcerated population than in the general population. With the increasing prevalence of chronic medical conditions and limited knowledge on foods accessible to the population, this study assessed the 4-week menu fed to all incarcerated males at state-run facilities in Alabama. Compared with the Acceptable Macronutrient Distribution Range for the average incarcerated male, the percentage of energy from total fat, saturated fat, sodium, and cholesterol exceeded the recommendation.

Dithiocarbamate-Based Sequence-Defined Oligomers as Promising Membrane-Disrupting Antibacterial Agents: Design, Activity, and Mechanism.

The emerging prevalence of antimicrobial resistance demands cutting-edge therapeutic agents to treat bacterial infections. We present a synthetic strategy to construct sequence-defined oligomers (SDOs) by using dithiocarbamate (DTC). The antibacterial activity of the synthesized library of SDOs was studied using a Gram-positive and a Gram-negative .

KaMLs for Predicting Protein p Values and Ionization States: Are Trees All You Need?

Despite its importance in understanding biology and computer-aided drug discovery, the accurate prediction of protein ionization states remains a formidable challenge. Physics-based approaches struggle to capture the small, competing contributions in the complex protein environment, while machine learning (ML) is hampered by the scarcity of experimental data. Here, we report the development of p ML (KaML) models based on decision trees and graph attention networks (GAT), exploiting physicochemical understanding and a new experiment p database (PKAD-3) enriched with highly shifted p's.

Modelling a pathological GSX2 variant that selectively alters DNA binding reveals hypomorphic mouse basal ganglia and hindbrain defects.

Gsx2 is a homeodomain transcription factor critical for development of the ventral telencephalon and hindbrain of the mouse. Loss of Gsx2 function results in severe basal ganglia dysgenesis as well as defects in the nucleus tractus solitarius (nTS) of the hindbrain together with respiratory failure at birth.

The role of the early-life gut microbiome in childhood asthma.

Asthma is a chronic disease affecting millions of children worldwide, and in severe cases requires hospitalization. The etiology of asthma is multifactorial, caused by both genetic and environmental factors. In recent years, the role of the early-life gut microbiome in relation to asthma has become apparent, supported by an increasing number of population studies, research, and intervention trials.

High Glucose Treatment Induces Nuclei Aggregation of Microvascular Endothelial Cells via the - Pathway.

Background: Hyperglycemia is a major contributor to endothelial dysfunction and blood vessel damage, leading to severe diabetic microvascular complications. Despite the growing body of research on the underlying mechanisms of endothelial cell (EC) dysfunction, the available drugs based on current knowledge fall short of effectively alleviating these complications. Therefore, our endeavor to explore novel insights into the cellular and molecular mechanisms of endothelial dysfunction is crucial for the field.

Logical Analysis of Multiple miRNAs with Isothermal Molecular Classifiers Based on LATE-RCA.

Logical analysis of multiple-miRNA expression information and immediate output of diagnostic results facilitates early cancer detection. In this work, we constructed an isothermal molecular classifier capable of performing computations on multiple miRNAs and directly providing diagnosis results. First, we developed linear-after-the-exponential rolling circle amplification (LATE-RCA), a nearly linear isothermal amplification that does not destroy the original quantitative information about miRNAs.

Cortical Neurotransmitters Measured by Magnetic Resonance Spectroscopy Change Following Traumatic Brachial Plexus Injury.

 GABA (γ-aminobutyric acid) is the major inhibitory neurotransmitter in the brain. In response to injury within the central nervous system, GABA promotes cortical plasticity and represents a potential pharmacological target to improve functional recovery. However, it is unclear how GABA changes in the brain after traumatic brachial plexus injuries (tBPIs) which represents the rationale for this pilot study.

Efficacy and safety of hydroxyurea therapy on patients with -thalassemia: a systematic review and meta-analysis.

Objective: Our aim is to review the safety and efficacy of hydroxyurea (HU) on -thalassemia patients.

Methods: Studies that evaluated the safety and efficacy of HU on β-thalassemia patients were searched in Pub-Med, Cochrane Databases, Web of Science, China-Biology-Medicine, CNKI, Embase, VIP, and WanFang data. The proportions of response rate (RR) (50% fall in transfusion need in transfusion-dependent -thalassemia patients, or 1 g/dL elevate in hemoglobin (Hb) levels in transfusion-independent -thalassemia patients) and good RR (transfusion-free in transfusion-dependent -thalassemia patients or 2 g/dL elevate in Hb levels in transfusion-independent β-thalassemia patients) were utilized to evaluate the effect size (ES).

Nuclear factor I-C regulates intramembranous bone formation via control of FGF signalling.

Our previous studies indicate that NFI-C is essential for tooth root development and endochondral ossification. However, its exact role in calvarial intramembranous bone formation remains unclear. In this study, we demonstrate that the disruption of the gene leads to defects in intramembranous bone formation, characterized by decreased osteogenic proliferative activity and reduced osteoblast differentiation during postnatal osteogenesis.
