The full range of long-term health consequences COVID-19 in patients who are discharged from hospital is largely unclear. aim our study was to comprehensively compare between 6 months and 12 after symptom onset among survivors with COVID-19.We undertook an ambidirectional cohort had been Jin Yin-tan Hospital (Wuhan, China) Jan 7 May 29, 2020. At 6-month 12-month follow-up visit, were interviewed questionnaires on symptoms health-related quality life (HRQoL), received a physical examination,...

Biological age measurements (BAs) assess aging-related physiological change and predict health risks among individuals of the same chronological (CA). Multiple BAs have been proposed are well studied individually but not jointly. We included 845 3973 repeated from a Swedish population-based cohort examined longitudinal trajectories, correlations, mortality associations nine across 20 years follow-up. found growth functional accelerated around 70; average levels BA curves differed by sex span...

Axonal degeneration is a hallmark of many neuropathies, neurodegenerative diseases, and injuries. Here, using Drosophila injury model, we have identified highly conserved E3 ubiquitin ligase, Highwire (Hiw), as an important regulator axonal synaptic degeneration. Mutations in hiw strongly inhibit Wallerian multiple neuron types developmental stages. This new phenotype mediated by downstream target Hiw: the NAD+ biosynthetic enzyme nicotinamide mononucleotide adenyltransferase (Nmnat), which...

Abstract Objective This study aimed to investigate the current situation of oral frailty (OF) in elderly community China and analyse its influencing factors. Methods Using convenience sampling, 380 people from three communities our city were selected as participants study. The Oral Frailty Index-8, Scale, Health Assessment Tool, Mini-nutritional Scale Pittsburgh Sleep Quality Index used OF Results In this study, categorized into groups: frailty, pre-frailty, non-physical based on their...

Frailty index (FI) is a well-established predictor of all-cause mortality, but less known for cause-specific mortality and whether familial effects influence the associations. Middle-aged individuals are also understudied association between FI mortality. Furthermore, population impact frailty remains understudied.We estimated predictive value taking into account factors, tested associations time-dependent. We assessed proportion deaths that attributable to increased levels frailty. analyzed...

The prognostic role of immune cells in amyotrophic lateral sclerosis (ALS) remains undetermined. Therefore, we conducted a longitudinal cohort study including 288 ALS patients with up to 5-year follow-up during 2015–2020 recruited at the only tertiary referral center for Stockholm, Sweden, and measured levels differential leukocytes lymphocyte subpopulations. primary outcome was risk death after diagnosis secondary outcomes included functional status disease progression rate. Cox model used...

Annexins are an evolutionarily conserved multigene family of calcium-dependent phospholipid binding proteins that play important roles in stress resistance and plant development. They have been relatively well characterized model plants Arabidopsis (Arabidopsis thaliana) rice (Oryza sativa), but nothing has reported hexaploid bread wheat (Triticum aestivum) barely (Hordeum vulgare), which the two most economically plants. Based on available genomic transcriptomic data, 25 11 putative annexin...

frailty shows an upward trajectory with age, and higher levels increase the risk of mortality. However, it is less known whether shape trajectories differs by age at death or rate change in associated mortality.to assess population to analyse current level index (FI) i.e. most recent measurement person-specific more predictive mortality.3,689 individuals from three population-based cohorts up 15 repeated measurements Rockwood were analysed.

Central nervous system (CNS) infections can cause significant morbidity and mortality, especially in children. Rapid accurate pathogenic detection suspected CNS is essential for disease control at the early stage of infection. To evaluate performance metagenomic next-generation sequencing (mNGS) cell-free DNA (cfDNA) cerebrospinal fluid (CSF) pediatric patients, we retrospectively analyzed efficiency cfDNA mNGS children with (n = 257) or noninfectious neurological disorders 81). The CSF...

Nitric oxide, when released into the bloodstream, is quickly scavenged by Hb in erythrocytes or oxidized to nitrite. Nitrite can also enter and oxidize Hb. The goals of this work were determine mechanism erythrocyte nitrite uptake whether causes oxidant stress these cells.
