Functional fitness and psychological well-being in older adults.

Background: Physical fitness and functioning are related to better mental health in older age. However, which fitness components (body composition, strength, flexibility, coordination, and endurance) are more closely related to psychological well-being (PWB) is unclear.

Methods: This research examined how body mass index (BMI) and six indices of functional fitness (i.

Predicting Biochemical and Physiological Parameters: Deep Learning from IgG Glycome Composition.

In immunoglobulin G (IgG), -glycosylation plays a pivotal role in structure and function. It is often altered in different diseases, suggesting that it could be a promising health biomarker. Studies indicate that IgG glycosylation not only associates with various diseases but also has predictive capabilities.

Resolving the Taxonomy of Mountain Syrphidae (Diptera) in the Iberian Peninsula: The Species Group of Becker, 1894.

The largest genus of Palaearctic Syrphidae, Meigen, 1822 (Syrphidae: Rhingiini), is currently under revision in the Ibero-Balearic region (Iberian Peninsula + Balearic Islands). Prior to this study, various species groups with putative phylogenetic support were defined for this genus of complex taxonomy. The group of Becker, 1894 includes species distributed all over Europe, with some of these species being similar each other in both morphology and genetics.

A Fullerton Functional Fitness Test-based exercise intervention for older adults yields quick physical and psychological benefits.

Objectives: Functional fitness is essential for healthy living in older adults. Specially targeted fitness programs might be the most beneficial. This intervention study aimed to assess the efficacy of a specific 16-week exercise program in improving functions as measured by the Fullerton Functional Fitness Test (FFFT), also known as the Senior Test, in older adults.

Malonate given at reperfusion prevents post-myocardial infarction heart failure by decreasing ischemia/reperfusion injury.

The mitochondrial metabolite succinate is a key driver of ischemia/reperfusion injury (IRI). Targeting succinate metabolism by inhibiting succinate dehydrogenase (SDH) upon reperfusion using malonate is an effective therapeutic strategy to achieve cardioprotection in the short term (< 24 h reperfusion) in mouse and pig in vivo myocardial infarction (MI) models. We aimed to assess whether inhibiting IRI with malonate given upon reperfusion could prevent post-MI heart failure (HF) assessed after 28 days.

Revisions of the and species groups of the genus Meigen, 1803 (Diptera, Syrphidae).

This study focuses on the lineage within the genus , exploring morphological, genetic, and distributional aspects of two related assemblies within this lineage: the and species groups. An integrative taxonomic approach was followed to ensure comprehensive species identification and validation, using adult morphology, wing geometric morphometrics, and genetic analysis of the mtDNA COI gene. In the group, seven species were identified, including three new species: Vujić, Radenković & Likov, , Vujić, Radenković & Likov, , and Vujić, Radenković & Likov, In the group, our revision revealed a new species, Vujić, Radenković & Likov, , and the revalidation of Gil Collado, 1929, Macquart, 1842 is redescribed.

Since the last checklist of 274 species published by de Groot & Govedič in 2008, a large number of additional specimens have been collected and studied. In the present study, 42 species are reported for the first time for the Slovenian hoverfly fauna.

Are Cyberchondria and Intolerance of Uncertainty Related to Smartphone Addiction?

Smartphones are a medium for performing online activities, and one such activity could be the compulsive online health information search - cyberchondria. This study aimed to test whether cyberchondria and intolerance of uncertainty (IU) positively predict smartphone addiction (SA), adjusted for age, gender, daily use duration, the reason for using smartphones, and symptoms of anxiety and depression. The sample consisted of 471 adults (55.

Recent fire in a Mediterranean ecosystem strengthens hoverfly populations and their interaction networks with plants.

Fire affects many critical ecological processes, including pollination, and effects of climate change on fire regimes may have profound consequences that are difficult to predict. Considerable work has examined effects of fire on pollinator diversity, but relatively few studies have examined these effects on interaction networks including those of pollinators other than bees. We examined the effects of a severe wildfire on hoverfly pollinators in a Mediterranean island system.

High species turnover and unique plant-pollinator interactions make a hyperdiverse mountain.

We studied α- and β-diversity of pollinators, flowering plants and plant-pollinator interactions along the altitudinal gradient of Mt. Olympus, a legendary mountain and biodiversity hotspot in Central Greece. We explored 10 study sites located on the north-eastern slope of the mountain, from 327 to 2596 m a.

Hypovitaminosis D in infants: Evidence that increased intake of vitamin D reduces the incidence of allergic and respiratory disorders.

Aim: The study assessed the relationship between vitamin D status in infants and the presence of allergic and/or respiratory disorders.

Materials And Methods: The study cohort comprised 81 hospitalized infants presenting at the Pediatric Clinic, University Clinical Center Kragujevac, Serbia, between January 2011 and June 2016.

Results: The age of the infants ranged from 29 days to 12 months.

Functional substitutions of amino acids that differ between GDF11 and GDF8 impact skeletal development and skeletal muscle.

Growth differentiation factor 11 (GDF11) and GDF8 (MSTN) are closely related TGF-β family proteins that interact with nearly identical signaling receptors and antagonists. However, GDF11 appears to activate SMAD2/3 more potently than GDF8 in vitro and in vivo. The ligands possess divergent structural properties, whereby substituting unique GDF11 amino acids into GDF8 enhanced the activity of the resulting chimeric GDF8.

Not all mentally stimulating activities are alike: insights from a 4-factor model and implications for late-life cognition.

It is not yet known which specific qualities of cognitively stimulating activities are most likely to enhance cognitive reserve in older adults. Taking an inductive approach to this problem, we asked 504 older adults with subjective and/or cognitive impairment to complete the Cognitively Stimulating Activities Questionnaire (CSA-Q). Exploratory factor analysis identified a 4-factor structure within a split-half sample, after which confirmatory factor analysis cross-validated the model.

Hedonic use, stress, and life satisfaction as predictors of smartphone addiction.

This study examined the relationship between hedonic smartphone use (entertainment, social media, games), perceived life stress, and satisfaction with life with smartphone addiction (SA). We tested the connections using structural equation modeling (SEM) on questionnaire data obtained from 410 participants (73.2% women).

Merodon capi Vujić et Radenković, 2020 and Merodon roni Radenković et Vujić, 2020 are two cryptic species belonging to the Merodon planifacies Bezzi, 1915 species complex that have recently been described, with the differences between them being revealed by molecular and geometric morphometry studies of adult specimens. In the present study, the preimaginal morphology of both species is described and displayed, with the material used corresponding to samples taken from bulbs of Merwilla plumbea (Lindl.) Speta plants at two locations in KwaZulu-Natal province (South Africa).

The connection between risk of smartphone addiction, type of smartphone use, life satisfaction, and perceived stress dataset.

The data were collected to test the hypothesis that problematic smartphone use, defined as the risk of smartphone addiction, is positively related to the type/purpose of device use (hedonic, meaning pleasure/gratification) and perceived stress, while it is negatively related to life satisfaction. The data were collected online between October 2020 and January 2021, using Qualtrics online research platform. The participants were aged 18 years or over, had a good command of the English language.

Contribution to the knowledge of the bee fauna (Hymenoptera, Apoidea, Anthophila) in Serbia.

The current work represents summarised data on the bee fauna in Serbia from previous publications, collections, and field data in the period from 1890 to 2020. A total of 706 species from all six of the globally widespread bee families is recorded; of the total number of recorded species, 314 have been confirmed by determination, while 392 species are from published data. Fourteen species, collected in the last three years, are the first published records of these taxa from Serbia: (Panzer, 1805), (Kirby, 1802), (Schenck, 1853), (Thomson, 1870), (Zetterstedt, 1838), (Pérez, 1895), (Noskiewicz, 1924), (Smith, 1851), (Morawitz, 1892), (Fabricius, 1775), (Kirby, 1802), (Pérez, 1895), (Thomson, 1872), and (Förster, 1855).

Engagement in cognitively stimulating activities in individuals with Mild Cognitive Impairment: relationships with neuropsychological domains and hippocampal volume.

Late-life participation in cognitively stimulating activities is thought to contribute to an individual's cognitive reserve and thus protect against cognitive decline, yet its association with clinical markers of neurodegeneration is not well established. To investigate, we developed a 13-item self-report "cognitively stimulating activities" questionnaire (CSA-Q), which was completed by a community sample of 269 older adults (>50 years) at risk of dementia. Participants met criteria for Mild Cognitive Impairment (MCI) and were classified as amnestic (aMCI; = 93) or non-amnestic (naMCI; = 176).
