Biodegradation of DDT using multi-species mixtures: From genome-mining prediction to practical assessment.

DDT (dichlorodiphenyltrichloroethane) is a commonly used insecticide that is recalcitrant and highly stable in the environment. Currently, DDT residue contamination, especially in agricultural soil, is still a concern in many countries, threatening human health and the environment. Among the approaches to resolve such an issue, novel biodegradation-based methods are now preferred to physicochemical methods, due to the sustainability and the effectiveness of the former.

A 9-Fr Endovascular Therapy Transducer With an Acoustic Metamaterial Lens for Rapid Stroke Thrombectomy.

Large vessel occlusion (LVO) stroke, in which major cerebral arteries such as the internal carotid and middle cerebral arteries supplying the brain are occluded, is the most debilitating form of acute ischemic stroke (AIS). The current gold standard treatment for LVO stroke is mechanical thrombectomy; however, initial attempts to recanalize these large, proximal arteries supplying the brain fail in up to 75% of cases, leading to repeated passes that decrease the likelihood of success and affect patient outcomes. We report the design, fabrication, and testing of a mm forward-treating ultrasound (US) transducer with an acoustic metamaterial lens to dissolve blood clots recalcitrant to first-pass mechanical thrombectomy in LVO stroke.

Association of race and ethnicity with the development of cystic fibrosis-related diabetes.

Background: CF-related diabetes (CFRD) is a common, life-expectancy limiting complication of CF. While Black race and Hispanic ethnicity in youth-onset type 1 and type 2 diabetes are well-recognized risk factors for worse diabetes complications, the potential for racial/ethnic disparities in CFRD has received limited attention.

Methods: We conducted a retrospective cohort study utilizing the CF Foundation Patient Registry from 2010 to 2019 to determine the prevalence and incidence of CFRD by race/ethnicity.

Estimating minimal clinically important difference (MCID) for gastrointestinal symptoms in cystic fibrosis.

Background: Minimal clinically important difference (MCID) is important to establish as a meaningful outcome in research when using patient reported outcome measures (PROMs). We determined the MCID using the distribution-based approach for three measurements used as part of the GALAXY study, which is an observational prospective study on gastrointestinal (GI) symptoms in cystic fibrosis (CF).

Methods: Four hundred and two persons with cystic fibrosis (PwCF) participated in the GALAXY study, all with baseline values available for all questionnaires.

Generation of a biliary tract cancer cell line atlas reveals molecular subtypes and therapeutic targets.

Biliary tract cancers (BTCs) are a group of deadly malignancies encompassing intrahepatic and extrahepatic cholangiocarcinoma, gallbladder carcinoma, and ampullary carcinoma. Here, we present the integrative analysis of 63 BTC cell lines via multi-omics clustering and genome- scale CRISPR screens, providing a platform to illuminate BTC biology and inform therapeutic development. We identify dependencies broadly enriched in BTC compared to other cancers as well as dependencies selective to the anatomic subtypes.

CT imaging-derived phenotypes for abdominal muscle and their association with age and sex in a medical biobank.

The study of muscle mass as an imaging-derived phenotype (IDP) may yield new insights into determining the normal and pathologic variations in muscle mass in the population. This can be done by determining 3D abdominal muscle mass from 12 distinct abdominal muscle regions and groups using computed tomography (CT) in a racially diverse medical biobank. To develop a fully automatic technique for assessment of CT abdominal muscle IDPs and preliminarily determine abdominal muscle IDP variations with age and sex in a clinically and racially diverse medical biobank.

Orally administered boldine reduces muscle atrophy and promotes neuromuscular recovery in a rodent model of delayed nerve repair.

Peripheral nerve injury often results in poor functional recovery due to a prolonged period of muscle denervation. In particular, absent axonal contact, denervated muscle can undergo irrevocable atrophy and diminished receptiveness for reinnervation over time, ultimately reducing the likelihood for meaningful neuromuscular recovery. While innovative surgical approaches can minimize the harmful effects of denervation by re-routing neighboring-otherwise uninjured-axons, there are no clinically-available approaches to preserve the reinnervation capacity of denervated muscles.
