Objective: To explore additional dietary risk factors, other than those already known, according to the Ayurvedic perspective in CRC patients.

Methods: Detail dietary data was collected from 420 patients of CRC and 116 healthy volunteers registered at our institute with the help of a food frequency questionnaire.

Immunoactive signatures of circulating tRNA- and rRNA-derived RNAs in chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is the most prevalent lung disease, and macrophages play a central role in the inflammatory response in COPD. We here report a comprehensive characterization of circulating short non-coding RNAs (sncRNAs) in plasma from patients with COPD. While circulating sncRNAs are increasingly recognized for their regulatory roles and biomarker potential in various diseases, the conventional RNA sequencing (RNA-seq) method cannot fully capture these circulating sncRNAs due to their heterogeneous terminal structures.

The evolution of computational research in a data-centric world.

Computational data-centric research techniques play a prevalent and multi-disciplinary role in life science research. In the past, scientists in wet labs generated the data, and computational researchers focused on creating tools for the analysis of those data. Computational researchers are now becoming more independent and taking leadership roles within biomedical projects, leveraging the increased availability of public data.

A-Kinase-Anchoring-Protein Subtypes Differentially Regulate GPCR Signaling and Function in Human Airway Smooth Muscle.

A-kinase-anchoring proteins (AKAPs) act as scaffold proteins that anchor the regulatory subunits of the cAMP-dependent protein kinase A (PKA) to coordinate and compartmentalize signaling elements and signals downstream of Gs-coupled G protein-coupled receptors (GPCRs). The beta-2-adrenoceptor (βAR), as well as the Gs-coupled EP2 and EP4 receptor subtypes of the E-prostanoid (EP) receptor subfamily, are effective regulators of multiple airway smooth muscle (ASM) cell functions whose dysregulation contributes of asthma pathobiology. Here, we identify specific roles of the AKAPs Ezrin and Gravin, in differentially regulating PKA substrates downstream of the βAR, EP2 receptor (EP2R) and EP4 receptor (EP4R).

CD38/cADPR-mediated calcium signaling in a human myometrial smooth muscle cell line, PHM1.

Cyclic ADP-ribose (cADPR) has emerged as a calcium-regulating second messenger in smooth muscle cells. CD38 protein possesses ADP-ribosyl cyclase and cADPR hydrolase activities and mediates cADPR synthesis and degradation. We have previously shown that CD38 expression is regulated by estrogen and progesterone in the myometrium.

Molecular mechanism of bitter taste receptor agonist-mediated relaxation of airway smooth muscle.

G-protein-coupled receptors (GPCRs) belonging to the type 2 taste receptors (TAS2Rs) family are predominantly present in taste cells to allow the perception of bitter-tasting compounds. TAS2Rs have also been shown to be expressed in human airway smooth muscle (ASM), and TAS2R agonists relax ASM cells and bronchodilate airways despite elevating intracellular calcium. This calcium "paradox" (calcium mediates contraction by pro-contractile Gq-coupled GPCRs) and the mechanisms by which TAS2R agonists relax ASM remain poorly understood.

The Association Between Tranexamic Acid and Seizures in Moderate or Severe Traumatic Brain Injury.

Introduction: Tranexamic acid (TXA) administered within 2 h of injury reduces mortality in traumatic brain injury (TBI) with intracranial hemorrhage. TXA also reduces the seizure threshold in a dose-dependent manner. We examined whether a 2-g bolus of prehospital TXA administered in moderate or severe TBI is associated with seizure activity within 72 h of injury.

Superoxide Anions Inhibit Intracellular Calcium Response in Porcine Airway Smooth Muscle Cells.

 Superoxide anions (O ) have multiple effects on pulmonary parenchyma altering cell proliferation, cellular metabolism, and airway smooth muscle (ASM) contraction. Intracellular calcium ([Ca ] ) concentration plays a significant role in the regulation of ASM contraction, relaxation, proliferation, and gene expression.  We investigated the effects of O on agonist-stimulated changes in [Ca ] in ASM cells.

Diacylglycerol kinase is a keystone regulator of signaling relevant to the pathophysiology of asthma.

Signal transduction by G protein-coupled receptors (GPCRs), receptor tyrosine kinases (RTKs) and immunoreceptors converge at the activation of phospholipase C (PLC) for the hydrolysis of phosphatidylinositol 4,5-bisphosphate (PIP) into inositol 1,4,5-trisphosphate (IP) and diacylglycerol (DAG). This is a point for second-messenger bifurcation where DAG via protein kinase C (PKC) and IP via calcium activate distinct protein targets and regulate cellular functions. IP signaling is regulated by multiple calcium influx and efflux proteins involved in calcium homeostasis.

Antibacterial Effect of Two Novel Sealants: A Laboratory-Based Study.

Background: This research sought to assess the impact of polyhexamethylene guanidine hydrochloride (PHMGH) and 1,3,5-triacryloyl hexahydro-1,3,5-triazine (TAT) on the antibacterial activity of an experimental resin sealant.

Materials And Methods: The two experimental sealants were formulated based on previous research, and was tested for biofilm and planktonic bacteria's antibacterial properties. In 48 hours, 300 L of frozen in skim milk was stored in an oven at 37°C in a microaerophilic atmosphere with 5% of CO2 and put on a petri plate containing brain-heart infusion (BHI) broth with agar at 15 g/L.

Interleukin 31 receptor α promotes smooth muscle cell contraction and airway hyperresponsiveness in asthma.

Asthma is a chronic inflammatory airway disease characterized by airway hyperresponsiveness (AHR), inflammation, and goblet cell hyperplasia. Multiple cytokines, including IFNγ, IL-4, and IL-13 are associated with asthma; however, the mechanisms underlying the effects of these cytokines remain unclear. Here, we report a significant increase in the expression of IL-31RA, but not its cognate ligand IL-31, in mouse models of allergic asthma.

Whole blood transcriptomics identifies subclasses of pediatric septic shock.

Background: Sepsis is a highly heterogeneous syndrome, which has hindered the development of effective therapies. This has prompted investigators to develop a precision medicine approach aimed at identifying biologically homogenous subgroups of patients with septic shock and critical illnesses. Transcriptomic analysis can identify subclasses derived from differences in underlying pathophysiological processes that may provide the basis for new targeted therapies.

Genomic surveillance reveals early detection and transition of delta to omicron lineages of SARS-CoV-2 variants in wastewater treatment plants of Pune, India.

The COVID-19 pandemic has emphasized the urgency for rapid public health surveillance methods to detect and monitor the transmission of infectious diseases. The wastewater-based epidemiology (WBE) has emerged as a promising tool for proactive analysis and quantification of infectious pathogens within a population before clinical cases emerge. In the present study, we aimed to assess the trend and dynamics of SARS-CoV-2 variants using a longitudinal approach.

Diacylglycerol kinase zeta deficiency attenuates papain-induced type 2 airway inflammation.

Allergic airway diseases are caused by inappropriate immune responses directed against inhaled environmental antigens. We previously reported that the inhibition of diacylglycerol (DAG) kinaseζ (DGKζ),an enzyme that terminates DAG-mediated signaling,protects against T cell-mediated allergic airway inflammation by blocking Th2 cell differentiation.In this study, we tested whether DGKζ deficiency also affects allergic airway disease mediated by type 2 innate lymphoid cells (ILC2)s.

Proteomics-Based Approach for Detailing the Allergenic Profile of Cannabis Chemotypes.

Allergic sensitization to cannabis is an emerging public health concern and is difficult to clinically establish owing to lack of standardized diagnostic approaches. Attempts to develop diagnostic tools were largely hampered by the Schedule I restrictions on cannabis, which limited accessibility for research. Recently, however, hemp was removed from the classified list, and increased accessibility to hemp allows for the evaluation of its practical clinical value for allergy diagnosis.
