Lysergic acid diethylamide (LSD) is an ergot-derived psychedelic agent that produces perceptual and psychic effects of heightened sensations by acting on the dopaminergic, adrenergic, and serotonergic pathways in the brain and periphery, with 5-hydroxytryptamine 2A (5-HT2A) as the primary target molecule. Its action on these receptors in the central nervous system is comparatively well studied with respect to the psychedelic effects; however, there is speculative evidence of cardioprotective effects in the current literature attributed to the usage of this substance, even though acute ingestion causes tachycardia and hypertension, just like other psychedelics. Larger recreational doses of the drug can lead to cardiovascular and cerebrovascular incidents, but chronic peripheral antagonism of 5-HT2A receptors by the drug reduces atherosclerotic and thrombotic processes due to a reduction in platelet aggregation and vascular smooth muscle cell proliferation.

Evidence is lacking for guiding optimal combination hypertension therapy in South Asian patients. Here we investigated the blood pressure (BP)-lowering efficacy and safety of three commonly recommended antihypertensive dual combinations in a multicenter, single-blinded trial conducted in India. We randomized Indians aged 30-79 years (mean age, 52 years) with mean sitting systolic blood pressure (SBP) of 150-179 mmHg on no treatment or an SBP of 140-159 mmHg on monotherapy 1:1:1 to a single-pill combination of amlodipine-perindopril, perindopril-indapamide or amlodipine-indapamide.

A standard 2-wk cage change frequency for individually ventilated mouse cages is used in many research facilities, with negligible effects on animal health and welfare. However, these techniques rely on subjective visual evaluations and often require spot changes. In this study, we describe the use and validation of digital monitoring technology to objectively determine the necessity of a cage change for mice.

Establishing a screening method for rodent pathogens is an integral component of an institution's rodent health surveillance program. Most rodent quarantine programs use direct colony sampling (DCS) from live animals for pathogen PCR testing. DCS may elicit undue stress to the animal and be time consuming, contingent on the number of quarantined animals.

High-sensitivity C-reactive protein (hs-CRP) is a key marker of inflammation, predominantly produced by hepatocytes and various tissues, including intracardiac tissue, atherosclerotic plaques, and vascular smooth muscles. The biomarker serves as a crucial element of innate immunity and rises in response to various disease processes, including infections and cancers. This rise is triggered by the release of cytokines, primarily interleukin-6, tumor necrosis factor, and interleukin-1β.

Nucleic acids have lately been explored as one of the significant strategies for cancer treatment. Despite their potential as a promising therapeutic tool in cancer therapy, these often face challenges of rapid degradation, insufficient cellular uptake, and poor targeting abilities. In this regard, nanotechnology has revolutionized nucleic acid-based cancer therapy.

Mediastinal haematoma post permanent pacemaker insertion (PPI) is a rare complication. We report the case of a woman in her 60s with symptomatic complete heart block, who developed symptoms of respiratory distress following the PPI procedure. Radiological investigations revealed a large mediastinal haematoma.

Bromocriptine mesylate (BM) is a well-established antiparkinsonian drug, yet its analytical methodologies remain limited in terms of efficiency, cost-effectiveness, and reproducibility from commercial product and biological samples. We aimed at systematic analytical quality by design-assisted method development for routine quantitative assessment. Initially, various plausible variables (peak area, retention time, tailing factor, and plates) were screened using Ishikawa fishbone method.

The review explores the innovative use of rice residue for developing Cellulose nanocrystals and reinforcement applications of CNCs for wastewater treatment. Rice residue, rich in lignocellulose components like cellulose, hemicellulose, and lignin, presents a sustainable resource for biocomposite fabrication. The review highlights the significant challenges of managing rice residue, particularly the environmental impact of its open field burning, which contributes to severe air pollution and health risks.

Background: Cadmium (Cd) contamination in soils is a pressing environmental issue due to its toxicity and persistence. Given the diverse geological formations and intensive agricultural activities in Ireland, understanding the distribution and sources of soil Cd is particularly important.

Methods: This study used multiple GIS-based and spatial machine learning (SML) techniques to investigate the spatial distribution and controlling factors of Cd in 16,783 topsoil samples across the island of Ireland.

Background: Geographical cohorting in hospital settings represents a significant shift from traditional patient rounding practices and aims to enhance the efficiency of health care delivery. This model assigns hospitalists to a particular inpatient unit, where most of their patients are located. While this model has several benefits, including streamlining health care procedures, optimizing resource allocation, and fostering better provider communication, its implementation is not without its challenges.

Eradication of pathogens from mouse colonies is crucial for scientific research reproducibility and animal welfare. The previously described techniques for eradicating pathogens by rederivation through embryo transfer or caesarian technique can be costly and technically challenging. The objective of our study was to assess the efficacy of iodine immersion combined with cross-fostering for eradicating murine norovirus (MNV) and Helicobacter spp.

Loeffler's syndrome is a rare, benign respiratory disease usually associated with peripheral eosinophilia, first described by Wilhelm Loeffler in 1932. It is caused by the larvae of helminths such as hookworms, , and S that transmigrate through the lungs during the active phase of infection. We present a case of a 53-year-old man who complained of a productive cough with intermittent hemoptysis and left-sided posterior chest pain.

Carfilzomib is a tetrapeptide epoxyketone that has shown potential clinical outcomes in the treatment of multiple myeloma. However, inaccuracies in quantifying such peptide drug products have arisen due to poor stability, low solubility, time-consuming techniques, complex physicochemical properties, and use of non-green solvents with less recyclability. This provides a substantial urge to develop an ecological and sensitive analytical method for quantifying peptide drugs from matrix formulation and biological samples in early as well as lateral stages of product development in pharma industries.
