Cichocki, Shinji Furuya, Abhishek Venkatratnam, Thomas J. McDonald, Anthony H. Knap, Terry Wade, Stephen Sweet, Weihsueh A. Chiu, David W. Threadgill, and Ivan Rusyn Researchers have spent more than a decade perfecting an alternative laboratory mouse model—the Collaborative Cross (CC)—that is designed to mimic the genetic diversity of the human population.1 This issue of Environmental Health Perspectives contains the first published toxicology study to be performed with CC mice: an exploration of how the toxic effects of perchloroethylene vary from animal to animal.2 Most inbred mouse strains are genetically identical, which means that individuals from the same strain respond similarly to the same chemical exposure. This limits re...

This study provides strong evidence that following a healthy lifestyle can substantially extend the years a person lives disease-free." Commentary on Recent Evidence for Cognitive Decline to Precede Amyloid Aggregation in Alzheimer's Disease https://www.fightaging.org/archives/2020/01/commentary-on-recent-evidence-for-cognitive-decline-to-precede-amyloid-aggregation-in-alzheimers-disease/ I can't say that I think the data presented in the research noted here merits quite the degree of the attention that it has been given in the popular science press. It is interesting, but not compelling if its role...

AbstractPatients with hematologic cancers often develop acute and chronic oral complications from their disease and its treatment. These problems could change patients ’ oral health-related quality of life (OHRQoL) negatively. Quality of life (QoL) has become an increasingly important outcome measure in oncology. This systematic literature review evaluates the impact of hematological malignancies and their treatment on OHRQoL as assessed by the Oral Health Impa ct Profile (OHIP-14) questionnaire. Medline through Pubmed and Web of Science were searched through April 2017. Two randomized controlled trials, one coh...

This study presents the effects of berberine (BBR) on the aging process resulting in a promising extension of lifespan in model organisms. BBR extended the replicative lifespan, improved the morphology, and boosted rejuvenation markers of replicative senescence in human fetal lung diploid fibroblasts. BBR also rescued senescent cells with late population doubling (PD). Furthermore, the senescence-associated β-galactosidase (SA-β-gal)-positive cell rates of late PD cells grown in the BBR-containing medium were ~72% lower than those of control cells, and its morphology resembled that of young cells. Mechanistically...

The dangers of alcohol begin at the first sip of the first drink. Although most responsible drinking habits shouldn’t be cause for major concern, everyone who drinks runs the risk of encountering the negative effects of alcohol. The Dietary Guidelines for Americans defines moderate drinking as up to 1 drink per day for women and up to 2 drinks per day for men.  A single drink is considered as: 12 ounces of beer (5% alcohol content) 8 ounces of malt liquor (7% alcohol content) 5 ounces of wine (12% alcohol content) 1.5 ounces of 80-proof (40% alcohol content) distilled spirits or liquor (e.g., gin, rum, vodka, ...

In this study, by adenovirus-mediated delivery and inducible transgenic mouse models, we demonstrate the proliferation of both HCs and SCs by combined Notch1 and Myc activation in in vitro and in vivo inner ear adult mouse models. These proliferating mature SCs and HCs maintain their respective identities. Moreover, when presented with HC induction signals, reprogrammed adult SCs transdifferentiate into HC-like cells both in vitro and in vivo. Finally, our data suggest that regenerated HC-like cells likely possess functional transduction channels and are able to form connections with adult auditory neurons. Epige...

AbstractRadial forearm free flap (RAFF) is the workhorse flap for oral cavity reconstruction. In the context of oncological reconstruction with radial forearm flap, the patient-reported outcomes of donor site morbidity amongst Indian patients have not been reported previously. Cultural and racial differences prevent extrapolation of morbidity data from Western literature. We aimed to evaluate subjectively the subjective long-term functional and aesthetic outcomes of the RAFF donor site. Patients who underwent RAFF reconstruction for intra-oral defects between 2014 and 2016 were included. Two questionnaires (Cosmesis and Se...

In this study, researchers studied 438,952 participants in the UK Biobank, who had a total of 24,980 major coronary events - defined as the first occurrence of non-fatal heart attack, ischaemic stroke, or death due to coronary heart disease. They used an approach called Mendelian randomisation, which uses naturally occurring genetic differences to randomly divide the participants into groups, mimicking the effects of running a clinical trial. People with genes associated with lower blood pressure, lower LDL cholesterol, and a combination of both were put into different groups, and compared against those without thes...

This study aimed to investigate the contribution of motor changes to oral mucositis in children and adolescents with cancer undergoing antineoplastic treatment in a referral hospital. This was an observational, cross-sectional study with 70 patients aged 2 to 19 years, diagnosed with any type of cancer and treated in a pediatric hospital cancer ward from April to September 2017. A questionnaire related to the patients’ socioeconomic and clinical conditions was used, followed by the Oral Assessment Guide and selected domains of the activity and participation section of the International Classification of Functioni...
