Feasibility Study of a Non-Contact Differentiation of Cannabidiol Concentrations Using Interdigital Electrodes.

This feasibility study presents a novel noncontact method for differentiating standard cannabidiol (CBD) concentrations using optimized interdigital electrodes. The electrode design, with a 100 mm sensing area on a 64 mm × 77 mm FR-4 substrate, was improved through finite element analysis. Methanol-CBD solutions (25-1000 ppm) in 2 mL glass vials were analyzed using a vector network analyzer connected via a high-frequency SMA connector, focusing on scattering parameter (S-parameter) changes.

Activity of Bambara Groundnut Seed Coat Extract Against Species: Efficacy and Mechanisms of Action.

The Bambara groundnut is the indigenous legume in the southern part of Thailand. It contains a seed coat rich in polyphenols, which can serve as natural antimicrobial agents. The extracts from red and white seed coats of Bambara groundnuts, namely RSC and WSC, respectively, were prepared using an ultrasound-assisted extraction process.

Automated classification of cellular expression in multiplexed imaging data with Nimbus.

Multiplexed imaging offers a powerful approach to characterize the spatial topography of tissues in both health and disease. To analyze such data, the specific combination of markers that are present in each cell must be enumerated to enable accurate phenotyping, a process that often relies on unsupervised clustering. We constructed the Pan-Multiplex (Pan-M) dataset containing 197 million distinct annotations of marker expression across 15 different cell types.

Optimal-Band Analysis for Chlorophyll Quantification in Rice Leaves Using a Custom Hyperspectral Imaging System.

Hyperspectral imaging (HSI) is a promising tool in chlorophyll quantification, providing a non-invasive method to collect important information for effective crop management. HSI contributes to food security solutions by optimising crop yields. In this study, we presented a custom HSI system specifically designed to provide a quantitative analysis of leaf chlorophyll content (LCC).

Determination of scattered radiation dose for radiological staff during portable chest examinations of COVID-19 patients.

The COVID-19 pandemic has resulted in a large increase in the number of patients admitted to hospitals. Radiological technologists (RTs) are often required to perform portable chest X-ray radiography on these patients. Normally, when performing a portable X-ray, radiation protection equipment is critical as it reduces the scatter radiation dose to hospital workers.

Dimorphism in the T-cell receptor constant region affects T-cell function, phenotype and HIV outcome.

Objectives: CD8 T cells recognize human leukocyte antigen-peptide complex through the T-cell receptor. Although amino acid variation in T-cell receptor variable chains often affects antigen specificity, dimorphism in the beta chain constant region (TRBC1 and TRBC2) is not thought to affect T-cell function. A recent study suggested that adoptive transfer of TRBC1-specific chimeric antigen-receptor-T cells provided an option for T-cell leukemia therapy that preserved T-cell immunity in the TRBC2 subset.

Fabrication of pluronic and methylcellulose for etidronate delivery and their application for osteogenesis.

Novel hydrogels were prepared by blending 4% (w/w) methylcellulose (MC) with various concentrations of 12, 14, 16, 18 and 20% (w/w) pluronic F127 (PF) to form injectable implant drug delivery systems. The blends formed gels using lower concentrations of PF compared to when using PF alone. Etidronate sodium (EDS) at a concentration of 4×10(-3)M was loaded into these blends for producing an osteogenesis effect.

Device-associated infections and patterns of antimicrobial resistance in a medical-surgical intensive care unit in a university hospital in Thailand.

Background: Surveillance of nosocomial infection in the intensive care unit (ICU) received a high level of attention and outcome indicators are now used in benchmarking the quality of patient care. Since 1999 the surveillance has targeted three site-specific, device-associated infections, including ventilator-associated pneumonia (VAP), central-line-related bloodstream infection (CR-BSI), and catheter-related urinary tract infection (CR-UTI). The authors conducted a two-year prospective study on the incidences of these infections acquired in an ICU and report herein, together with the antibiotic susceptibility patterns of the microorganisms isolated in an ICU.

Direct identification of Mycobacterium tuberculosis from sputum on Ziehl-Neelsen acid fast stained slides by use of silica-based filter combined with polymerase chain reaction assay.

This paper describes a method for isolation of deoxyribonucleic acid (DNA) from Ziehl-Neelsen stained sputum smears on glass slides; and isolated DNA was used for the IS6110 polymerase chain reaction (PCR)-based identification of M. tuberculosis. A total of 221 samples from newly diagnosed suspected tuberculosis cases were first examined by microscopic examination.
