The bark of the tree Terminalia arjuna (Roxb.) is widely used in Indian medicine (Ayurveda) for various cardiovascular ailments. The bark has been reported to contain several bioactive compounds. Many experimental studies have reported its antioxidant, anti-ischemic, antihypertensive, and antihypertrophic effects, which have relevance to its therapeutic potential in cardiovascular diseases in humans. Several clinical studies have reported its efficacy mostly in patients with ischemic heart disease, hypertension, and heart failure. However, a major shortcoming in all these experimental and clinical studies is the absence of phytochemical standardization of the extracts. In addition, many clinical studies are poor in terms of design and methods used for generating safety data. This review discusses how to address all these issues for a scientific validation of this medicinal plant.

Research suggests that the quality of care provided by family members may be influenced by the quality of relationship they have with the person living with dementia. The study investigated this in the context of assisting with daily activities. The quality of the relationship was assessed using the conceptual framework of relationship continuity/discontinuity which focuses on whether the carer experiences their relationship as continuous or discontinuous with the pre-dementia relationship.

Background/purpose: Although clinical studies have suggested a link between non-axial forces and reduced longevity of cervical restorations, the underlying mechanisms require further numerical investigation. This in-silico study employed a cohesive zone model (CZM) to investigate interfacial damage in a cervical restoration subjected to different load directions.
Materials And Methods: A plane strain model of a maxillary premolar was established, with a wedge-shaped buccal cervical restoration.

Functional substrate mapping has emerged as an essential tool for electrophysiologists, overcoming many limitations of conventional mapping techniques and demonstrating favourable long-term outcomes in clinical studies. However, a consensus on the definition of 'functional substrate' mapping remains elusive, hindering a structured approach to research in the field. In this review, we highlight the differences between 'functional mapping' techniques (which assess tissue response to the 'electrophysiological stress' using short coupled extrastimuli) and those highlighting regions of slow conduction during sinus rhythm.

The increased cost and morbidity associated with diabetic foot ulcers (DFUs) place a substantial strain on the entire global healthcare system. In this trial, 24 subjects with a chronic DFU, Wagner grade 1 (University of Texas grade 1A), were treated with Standard of Care (SOC) therapy and randomized, one-half to receive advanced high-purity Type-I collagen-based skin substitute (HPTC; manufactured by Encoll Corp., Fremont, CA, USA), and the other half to receive a dehydrated human amnion/chorion membrane (dHACM) or viable cryopreserved human placental membrane (vCHPM).

Background: The BCG vaccine induces trained immunity, an epigenetic-mediated increase in innate immune responsiveness. Therefore, this clinical trial evaluated if BCG-induced trained immunity could decrease coronavirus disease 2019 (COVID-19)-related frequency or severity.
Methods: A double-blind, placebo-controlled clinical trial of healthcare workers randomized participants to vaccination with BCG TICE or placebo (saline).
