Islet transplantation is becoming an established treatment option for managing a subset of adult patients who have type 1 diabetes mellitus. The success of this procedure is dependent upon the recovery of a sufficient number of functional human islets from donor organs for subsequent transplant. Here, the use of optimized bacterial collagenase-neutral protease enzyme mixtures has been shown to affect the yield and quality (defined by viability and glucose-stimulated insulin secretion) of islets recovered from human [...]

Elastic moduli of tissues and synthetic polymeric materials are important design properties needed to develop new implants. In this paper we report the use of vibrational optical coherence tomography (VOCT) to measure the resonant frequency and calculate the modulus of tissues and synthetic polymers non-invasively and non-destructively in vitro and in vivo. Values of tissue and polymer moduli were obtained by applying an audible sinusoidal sound wave to the surface of each specimen. The sound wave travels to the in [...]

In the United States (US), menopause occurs at an average age of 52. Menopausal symptoms tend to be maximal during the few years before and the year after menopause (during perimenopause), except for symptomatic vulvovaginal atrophy, which may worsen over time. Up to 20% of bone density loss occurs during the first 5 years after menopause, followed by an age-related bone loss rate similar to that in men. Menopause should be considered confirmed if an age-appropriate woman who is not pregnant has not had a menstrual [...]

This study addresses knowledge gaps concerning prevalence and risk factors for elder abuse among sexual minority (SM) compared to heterosexual Canadians aged 65+. Data derive from the Canadian Longitudinal Study on Aging, a national cohort study. Outcome variables include self-reports of psychological, physical, or financial abuse in the 12 months before interview and overall. Main explanatory variables are sexual orientation and gender identity; covariates include other socio-demographic characteristics, general a [...]

College students experience increased stress levels that could predispose them to develop mental and physical health conditions throughout adulthood. Yoga is an ancient mind-body practice including breath techniques, body exercises, and meditation that may be a useful strategy for enhancing college student health. Likewise, exposure to nature has been shown to have beneficial impacts on human health. This study investigates physiological and psychological responses of college students to yoga practiced in outdoor v [...]

A substantial share of the electric energy is generated with synchronous generators that provide sustained alternating current (AC) voltage and frequency energy to regional and national power systems, which subsequently transport and distribute it to diverse users. In an attempt to reduce environmental effects, electric energy markets have recently become more open, resulting in more flexible distributed electric power systems. In such distributed systems, stability, quick and efficient delivery, and control of ele [...]

Plastic pollution has received worldwide attention due to its extensive environmental and health implications. The circular economy has emerged as a potential solution to plastic pollution. This overview comprehensively presents different plastic circular economy approaches and discusses their advantages, disadvantages, and implementation challenges. It highlights that the current plastic circular economy approaches primarily comprise mechanical recycling, chemical recycling, bio-based and biodegradable plastics, e [...]

Background: This pilot trial investigated whether a 3-week self-help model for stress reduction using the Trauma Tapping Technique (TTT) would impact traumatized youth in the Democratic Republic of the Congo on post-traumatic stress symptoms and general happiness. It also focussed on the acceptability of the program to recipients and implementation in a community with complex trauma and conflict. Methods: The study involved 77 youth who received a TTT 3-week model of intervention (self-applied). Post traumatic stre [...]

In the past few years, there have been many attempts to commercialize Polymer Dispersed Liquid Crystal (PDLC) for Rear Projection Screen (RPS) in electrically switchable films and glass products. This application is based on the exceptional image quality of PDLC at a wide viewing angle. However, due to the high price of conventional switchable PDLC privacy glass, the integration of RPS in PDLC failed to attract large multimedia and entertainment markets. An obvious solution to this problem is the independent develo [...]
