Evaluation of a Computer-Tailored Healthy Ageing Intervention to Promote Physical Activity among Single Older Adults with a Chronic Disease

Janet M. Boekhout, Brenda Berendsen, Denise A. Peels et al. · 2018 · International Journal of Environmental Research and Public Health

This study explores the effectiveness of the Active Plus65 intervention designed to stimulate physical activity among single older adults with a chronic physical impairment. A quasi-experimental pre-test post-test study was performed. The intervention group (n = 411; mean age = 76.75; SD = 7.75) was assessed at baseline, three months, and six months. Data of comparable older adults who completed the original Active Plus intervention served as reference group (n = 87; mean age = 74.36; SD = 6.26). Multilevel regression analyses were applied: outcome measures were weekly minutes of moderate to v

Mechanism of the activation step of the aminoacylation reaction: a significant difference between class I and class II synthetases

Sindrila Dutta Banik, Nilashis Nandi · 2012 · Journal of Biomolecular Structure and Dynamics

In the present work we report, for the first time, a novel difference in the molecular mechanism of the activation step of aminoacylation reaction between the class I and class II aminoacyl tRNA synthetases (aaRSs). The observed difference is in the mode of nucleophilic attack by the oxygen atom of the carboxylic group of the substrate amino acid (AA) to the αP atom of adenosine triphosphate (ATP). The syn oxygen atom of the carboxylic group attacks the α-phosphorous atom (αP) of ATP in all class I aaRSs (except TrpRS) investigated, while the anti oxygen atom attacks in the case of class II aa

Factors associated with a higher rate of distant failure after primary treatment for glioblastoma

Sonia Tejada, Ricardo Díez-Valle, Guillermo Aldave et al. · 2013 · Journal of Neuro-Oncology

Our purpose was to analyze the pattern of failure in glioblastoma (GBM) patients at first recurrence after radiotherapy and temozolomide and its relationship with different factors. From 77 consecutive GBM patients treated at our institution with fluorescence guided surgery and standard radiochemotherapy, 58 first recurrences were identified and included in a retrospective review. Clinical data including age, Karnofsky performance score, preoperative tumor volume and location, extend of resection, MGMT promoter methylation status, time to progression (PFS), overall survival (OS) and adjuvant t

Management of Primary Biliary Cholangitis: Current Treatment and Future Perspectives

Romelia Barba Bernal, Bryan W. Ferrigno, Esli Medina Morales et al. · 2023 · The Turkish Journal of Gastroenterology

Primary biliary cholangitis is an autoimmune cholestatic liver disease characterized by progressive destruction of bile ducts, which can ultimately progress to chronic liver disease and cirrhosis. Ursodeoxycholic acid and obeticholic acid are the only 2 Food and Drug Administration (FDA)-approved medications for primary biliary cholangitis. Unfortunately, up to 40% of patients with primary biliary cholangitis have an incomplete response to ursodeoxycholic acid, warranting an essential need for additional therapeutics. Peroxisome proliferator-activated receptor agonists have shown promising dat

Treatment of displaced transverse fractures of the patella: modified tension band wiring technique with or without augmented circumferential cerclage wire fixation

Tien‐Yu Yang, Tsan-Wen Huang, Po‐Yao Chuang et al. · 2018 · BMC Musculoskeletal Disorders

BACKGROUND: Displaced transverse fractures of the body of the patella are usually associated with disruption of extensor mechanism and should be fixed surgically. The most common method is a tension band wiring (TBW) technique. Some surgeons concurrently employ an augmented circumferential cerclage wiring (ACCW) technique to help fracture stabilization and aid in fracture healing; however, its role and effect on the treatment outcomes is unclear. METHODS: We performed a STROBE-compliant retrospective observational cohort study on all cases of acute closed patella fracture that were treated at

Pre-Diagnostic Circulating Metabolites and Colorectal Cancer Risk in the Cancer Prevention Study-II Nutrition Cohort

Marjorie L. McCullough, Rebecca A. Hodge, Peter T. Campbell et al. · 2021 · Metabolites

Untargeted metabolomic studies have identified potential biomarkers of colorectal cancer risk, but evidence is still limited and broadly inconsistent. Among 39,239 Cancer Prevention Study II Nutrition cohort participants who provided a blood sample between 1998–2001, 517 newly diagnosed colorectal cancers were identified through 30 June 2015. In this nested case–control study, controls were matched 1:1 to cases on age, sex, race and date of blood draw. Mass spectroscopy-based metabolomic analyses of pre-diagnostic plasma identified 886 named metabolites, after quality control exclusions. Condi
