Comparative analysis of the antibacterial efficacy and bioactive components of Thuja occidentalis obtained from four different geographical sites.

The purpose of this study was to determine whether or not there were significant differences in the antibacterial potential of Thuja occidentalis collected from four distinct geographical sites, namely Chamba (Himachal Pradesh, India), Jalandhar (Punjab, India), Aurangabad (Bihar, India) and Kakching (Manipur, India). The plant extracts were prepared in three different solvents: ethanol, methanol, and acetone. The antibacterial potential of the plant extracts was tested against five different bacterial species using well diffusion test.

Tick-Borne Rhabdomyolysis: A Rare Case of Rhabdomyolysis and Acute Kidney Injury Due to Anaplasmosis.

Anaplasmosis is a tick-borne illness commonly seen in the northeastern states of the United States. The most common presenting signs are fever, malaise, and body aches accompanied by leukopenia, thrombocytopenia, and transaminitis. Rhabdomyolysis and acute kidney injury are rare presentations that can lead to significant morbidity.

A Rare Case of Pulmonary Cavitary Disease Caused by Mycobacterium xenopi.

Mycobacterium xenopi is a slow-growing, acid-fast, non-tuberculous mycobacterium (NTM). It is often considered to be a saprophyte or an environmental contaminant. Mycobacterium xenopi has low pathogenicity and is usually seen in patients with pre-existing chronic lung diseases and immunocompromised patients.

Human monkeypox: epidemiology, transmission, pathogenesis, immunology, diagnosis and therapeutics.

"Zoonoses" describe diseases that may be acquired by humans from animals. Due to the constant contact between humans and other animals, many infectious diseases are disseminated. This may happen via direct contact, such as bites or scratches, or by indirect contact, such as when eating bush meat or using contaminated animal parts.

Inhibiting ACK1-mediated phosphorylation of C-terminal Src kinase counteracts prostate cancer immune checkpoint blockade resistance.

Solid tumours are highly refractory to immune checkpoint blockade (ICB) therapies due to the functional impairment of effector T cells and their inefficient trafficking to tumours. T-cell activation is negatively regulated by C-terminal Src kinase (CSK); however, the exact mechanism remains unknown. Here we show that the conserved oncogenic tyrosine kinase Activated CDC42 kinase 1 (ACK1) is able to phosphorylate CSK at Tyrosine 18 (pY18), which enhances CSK function, constraining T-cell activation.

Discovery and molecular basis of subtype-selective cyclophilin inhibitors.

Although cyclophilins are attractive targets for probing biology and therapeutic intervention, no subtype-selective cyclophilin inhibitors have been described. We discovered novel cyclophilin inhibitors from the in vitro selection of a DNA-templated library of 256,000 drug-like macrocycles for cyclophilin D (CypD) affinity. Iterated macrocycle engineering guided by ten X-ray co-crystal structures yielded potent and selective inhibitors (half maximal inhibitory concentration (IC) = 10 nM) that bind the active site of CypD and also make novel interactions with non-conserved residues in the S2 pocket, an adjacent exo-site.

Rapid surveillance of COVID-19 by timely detection of geographically robust, alive and emerging hotspots using Particle Swarm Optimizer.

A novel virus, called severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly become a pandemic called Coronavirus disease 2019 (COVID-19). According to the World Health Organization, COVID-19 was first detected in Wuhan city in December 2019 and has affected 216 countries with 9473214 confirmed cases and 484249 deaths globally as on June 26th, 2020. Also, this outbreak continues to grow in many countries like the United States of America (U.

Use of cauliflower mosaic virus DNA markers to assess the potential for pathogen transmission from physicians' white coats.

In an observational study, the sleeves and pockets of physicians' white coats often directly or indirectly contacted patients and environmental surfaces. DNA markers on the sleeves or pockets were frequently transferred to surfaces and patients. These findings suggest that contaminated white coats have the potential to contribute to pathogen transmission.

Smart About Meds (SAM): a pilot randomized controlled trial of a mobile application to improve medication adherence following hospital discharge.

Objective: The objectives of this pilot study were (1) to assess the feasibility of a larger evaluation of Smart About Meds (SAM), a patient-centered medication management mobile application, and (2) to evaluate SAM's potential to improve outcomes of interest, including adherence to medication changes made at hospital discharge and the occurrence of adverse events.

Materials And Methods: We conducted a pilot randomized controlled trial among patients discharged from internal medicine units of an academic health center between June 2019 and March 2020. Block randomization was used to randomize patients to intervention (received access to SAM at discharge) or control (received usual care).

Smart about medications (SAM): a digital solution to enhance medication management following hospital discharge.

Objective: To outline the development of a software solution to improve medication management after hospital discharge, including its design, data sources, intrinsic features, and to evaluate the usability and the perception of use by end-users.

Materials And Methods: Patients were directly involved in the development using a User Center Design (UCD) approach. We conducted usability interviews prior to hospital discharge, before a user started using the application.

Use of viral DNA surrogate markers to study routes of transmission of healthcare-associated pathogens.

Background: The hands of healthcare personnel are the most important source for transmission of healthcare-associated pathogens. The role of contaminated fomites such as portable equipment, stethoscopes, and clothing of personnel in pathogen transmission is unclear.

Objective: To study routes of transmission of cauliflower mosaic virus DNA markers from 31 source patients and from environmental surfaces in their rooms.

Evaluation of a Mobile Application to Enhance Medication Management Following Hospital Discharge: Study Protocol for a Pilot Randomized Controlled Trial.

Over 3 million hospitalizations and 17 million ER visits occur in Canada each year. A substantial proportion of these encounters are preventable and attributable to medication non- adherence. Non-adherence to medication changes during discharge increases the risk of adverse events post-discharge.

Clothing and shoes of personnel as potential vectors for transfer of health care-associated pathogens to the community.

In an acute care hospital, we demonstrated that the clothing and shoes that physicians and nurses wear home from health care facilities can be contaminated with health care-associated pathogens, particularly methicillin-resistant Staphylococcus aureus. These findings suggest that the clothing and shoes of personnel have the potential to serve as vectors for the transfer of health care-associated pathogens to the community.

What Makes a Kinase Promiscuous for Inhibitors?

ATP-competitive kinase inhibitors often bind several kinases due to the high conservation of the ATP binding pocket. Through clustering analysis of a large kinome profiling dataset, we found a cluster of eight promiscuous kinases that on average bind more than five times more kinase inhibitors than the other 398 kinases in the dataset. To understand the structural basis of promiscuous inhibitor binding, we determined the co-crystal structure of the receptor tyrosine kinase DDR1 with the type I inhibitors dasatinib and VX-680.

Contaminated clothing of methicillin-resistant Staphylococcus aureus (MRSA) carriers is a potential source of transmission.

We examined the burden of methicillin-resistant Staphylococcus aureus (MRSA) on the clothing of MRSA carriers in a hospital and long-term care facility and assessed the potential for clothing to be a source of transmission. Of 50 MRSA carriers studied, 37 (74%) had MRSA recovered from clothing. For a subset of carriers with clothing contamination, transfer of MRSA from clothing to gloved hands and to a wheelchair occurred in 8 of 13 (62%) and 5 of 10 (50%) carriers, respectively.

This phase I trial tested the combination of pasireotide, docetaxel, and prednisone in pretreated mCRPC.

Patients And Methods: Chemotherapy naive mCRPC patients received docetaxel 75 mg/m intravenously every 21 days and pasireotide intramuscularly every 28 days at escalating dose levels of 40, 60, and 80 mg.

A small molecule inhibitor of Nicotinamide N-methyltransferase for the treatment of metabolic disorders.

Nicotinamide N-methyltransferase (NNMT) is a cytosolic enzyme that catalyzes the transfer of a methyl group from the co-factor S-adenosyl-L-methionine (SAM) onto the substrate, nicotinamide (NA) to form 1-methyl-nicotinamide (MNA). Higher NNMT expression and MNA concentrations have been associated with obesity and type-2 diabetes. Here we report a small molecule analog of NA, JBSNF-000088, that inhibits NNMT activity, reduces MNA levels and drives insulin sensitization, glucose modulation and body weight reduction in animal models of metabolic disease.
