Computed Tomography Coronary Angiography Is Feasible and Reliable for Proximal Coronary Segment Interpretation in Patients with Elevated Body Mass Index.

Computed tomography coronary angiography (CTCA) is under-utilised in detecting coronary artery disease (CAD) in obese patients due to concerns about non-evaluable testing. We hypothesise that these concerns are predominantly related to smaller and branch coronary vessels, and CTCA remains adequate for proximal segment stenosis interpretation, which has significant clinical implications. This retrospective cohort study, on consecutive patients referred for CTCA for suspected CAD, grouped patients by body mass index.

Gastrointestinal pathology in patients presenting with iron deficiency anaemia: A single-centre cross-sectional study.

Background: About a third of the world's population is estimated to suffer from anaemia, and iron deficiency is expected to account for about half of all anaemia cases. This study was designed to get an estimate of the proportion of patients with iron deficiency anaemia (IDA) who have a significant gastrointestinal (GI) pathology, in particular a GI malignancy, and to identify any risk factors or predictors for the same.

Methods: This cross-sectional study was conducted at a hospital in Eastern India.

Mechanistic Analysis of Peptide Affinity to Single-Walled Carbon Nanotubes and Volatile Organic Compounds Using Chemiresistors.

Peptides, due to their diverse and controllable properties, are used as both liquid and gas phase recognition elements for both biological and chemical targets. While it is well understood how binding of a peptide to a biomolecule can be converted into a sensing event, there is not the same mechanistic level of understanding with regard to how peptides modulate the selectivity of semiconductor/conductor-based gas sensors. Notably, a rational, mechanistic study has not yet been performed to correlate peptide properties to the sensor response for volatile organic compounds (VOCs) as a function of chemical properties.

SlipChip Enables the Integration of CRISPR-Cas12a and RPA for Fast and Stand-Alone HPV Detection.

Human papillomavirus (HPV) screening is vital for the early detection and prevention of cervical cancer. However, existing methods often face challenges related to speed, simplicity, and multiplexing, especially in resource-limited settings. Here we developed a portable SlipChip-based multiplexed and rapid nucleic acid testing platform, named SMART, designed to simultaneously detect HPV16 and HPV18.

Recent advances in heterogeneous porous Metal-Organic Framework catalysis for Suzuki-Miyaura cross-couplings.

Suzuki-Miyaura coupling (SMC), a crucial C-C cross-coupling reaction, is still associated with challenges such as high synthetic costs, intricate work-ups, and contamination with homogeneous metal catalysts. Research intensely focuses on strategies to convert homogeneous soluble metal catalysts into insoluble powder solids, promoting heterogeneous catalysis for easy recovery and reuse as well as for exploring greener reaction protocols. Metal-Organic Frameworks (MOFs), recognized for their high surface area, porosity, and presence of transition metals, are increasingly studied for developing heterogeneous SMC.
