Interest in targeted cancer therapy with alpha-emitting radionuclides is growing. To evaluate emerging radiotherapeutic agents requires precise activity measurements for consistent dose-response relationships and patient-specific dosimetry. National metrology institutes around the world have reported on the development and comparison of activity standards for medically important alpha emitters. This review describes the relevant methods and models underpinning these standards, the generation of new nuclear decay data, and the impacts on preclinical and clinical activity assays using radionuclide calibrators and γ-ray spectrometry.

KRAS is a proto-oncogene that is found to be mutated in 15% of all metastatic cancers with high prevalence in pancreatic, lung, and colorectal cancers. Additionally, patients harboring KRAS mutations respond poorly to standard cancer therapy. As a result, KRAS is seen as an attractive target for targeted anticancer therapy.

Around one-quarter of all patients undergoing cardiac procedures, particularly those on cardiopulmonary bypass, develop cardiac surgery-associated acute kidney injury (CSA-AKI). This complication increases the risk of several serious morbidities and of mortality, representing a significant burden for both patients and the healthcare system. Patients with diminished kidney function before surgery, such as those with chronic kidney disease, are at heightened risk of developing CSA-AKI and have poorer outcomes than patients without preexisting kidney injury who develop CSA-AKI.

A medicinal plant is any plant that in one or more of its organs contains substances that can be used by it or their constituent for therapeutic purposes. The present work was done to evaluate pharmacognostic, fluorescence, proximate and phytochemical analysis of ethanolic extracts of Cistanche tubulosa (Orobanchaceae) along with antimicrobial activity. Antimicrobial activity against four bacterial strains S.

Antimicrobial peptides (AMPs) may mitigate the danger of increasing antimicrobial resistance. We aimed to determine the activities of catestatin, temporin A, nisin and cecropin A against Bacteroides fragilis ATCC 25285, Prevotella melaninogenica ATCC 25845, Cutibacterium acnes ATCC 6919, Peptostreptococcus anaerobius ATCC 27337 and Peptostreptococcus stomatis DSM 17678. strains.

Background: Continuous Positive Airway Pressure (CPAP) treatment brings more benefits than risks to most coronary heart disease (CHD) patients with obstructive sleep apnea (OSA). However, the pathophysiological mechanism by which CPAP treatment improves the prognosis of patients with CHD and OSA remains unclear. The purpose of this study was to clarify whether CPAP can improve arterial stiffness and inflammatory factor levels in CHD patients with OSA, and to further improve prognosis.
