The heme nitric oxide/oxygen-binding proteins (H-NOX) are bacterial homologues of the sensor domain of mammalian soluble guanylate cyclase (sGC), a multidomain enzyme that catalyzes the production of cyclic guanosine monophosphate (cGMP) in response to NO. In facultative anaerobes, H-NOX proteins sense nitric oxide (NO) and regulate various communal behaviors including biofilm formation, motility, virulence, and quorum sensing. Rupture of the proximal heme iron-histidine bond during the formation of a five-coordinate low-spin ferrous nitrosyl (5cLS Fe(II)-NO) heme is thought to be required for H-NOX activation, allowing them to interact with downstream signaling partners such as diguanylate cyclases (DGC), phosphodiesterases (PDE), or histidine kinases (HK).

Many patients struggle to obtain goal LDL-C levels, despite the availability of several lipid-lowering medications, because of limited efficaciousness and unfavorable side effects. Proprotein convertase subtilisin/kexin type 9 (PCSK9) targeting has drawn interest recently as a novel approach to further lower cardiovascular (CV) risk.

SalivaDirect is a faster and easier method to implement than NPS sampling. Patients can self-collect saliva samples at home or in other non-clinical settings without the help of a healthcare professional.

Natural language processing and other artificial intelligence (AI) techniques provide novel methodologies that could be leveraged to extract clinically useful information from EHR resources.
Objective: Our aim is to develop a novel AI-enabled software prototype to identify adverse drug event (ADE) safety signals from free-text discharge summaries in EHRs to enhance opioid drug safety and research activities at the FDA.
Whole-genome sequencing (WGS) of influenza A virus (IAV) is crucial for identifying diverse subtypes and newly evolved variants and for selecting vaccine strains. In developing countries, where facilities are often inadequate, WGS is challenging to perform using conventional next-generation sequencers. In this study, we established a culture-independent, high-throughput native barcode amplicon sequencing workflow that can sequence all influenza subtypes directly from a clinical specimen.

Rodents and shrews live in close proximity to humans and have been identified as important hosts of zoonotic pathogens. This study aimed to detect Group A rotavirus (RVA) and its potential risk factors in rodents and shrews in Bangladesh. We captured 417 small mammals from 10 districts with a high degree of contact between people and domestic animals and collected rectal swab samples between June 2011 and October 2013.

Coronavirus disease 19 (COVID-19)-caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-has spread rapidly around the world. The global shortage of equipment and health care professionals, diagnostic cost, and difficulty in collecting nasopharyngeal swabs (NPSs) necessitate the use of an alternative specimen type for SARS-CoV-2 diagnosis. In this study, we investigated the use of saliva as an alternative specimen type for SARS-CoV-2 detection.

We found that 75% of the psychiatric inpatients have an unhealthy diet, which correlates with higher body mass index (BMI) and lower education level. We also found an increased sugar consumption in inpatients with schizophrenia.

Resistance to carbapenem antibiotics through the production of New Delhi metallo-β-lactamase-1 (NDM-1) constitutes an emerging challenge in the treatment of bacterial infections. To monitor the possible source of the spread of these organisms in Dhaka, Bangladesh, we conducted a comparative analysis of wastewater samples from hospital-adjacent areas (HAR) and from community areas (COM), as well as public tap water samples, for the occurrence and characteristics of NDM-1-producing bacteria. Of 72 HAR samples tested, 51 (71%) samples were positive for NDM-1-producing bacteria, as evidenced by phenotypic tests and the presence of the gene, compared to 5 of 41 (12.
