Abstract Confinement during the COVID‐19 pandemic is expected to have a serious and complex impact on mental health of patients with an eating disorder (ED) obesity. The present manuscript has following aims: (1) analyse psychometric properties COVID Isolation Eating Scale (CIES), (2) explore changes that occurred due confinement in symptomatology; (3) general acceptation use telemedicine confinement. sample comprised 121 participants (87 ED 34 obesity) recruited from six different centres....
Tau is a major microtubule-associated protein which induces bundling and stabilization of axonal microtubules (MTs). To investigate the interaction tau with MTs in living cells, we expressed GFP-tau fusion cultured Xenopus embryo neurons performed time-lapse imaging tau-labeled MTs. uniformly labeled individual regardless their assembly/disassembly status location along axon. Photobleaching experiments indicated that very dynamic, half-time fluorescence recovery order 3 seconds. Treatment...
Today, there is a need for the development of biomaterials with novel properties biomedical purposes. The biocompatibility materials key factor in determining its possible use biomedicine. In this study, composite cryogels were obtained based on pectin and chitosan using ionic cryotropic gelation. For cryogel preparation, apple (AP), Heracleum L. (HP), samples different physical chemical characteristics used. pectin-chitosan found to depend structural features physicochemical within them....
Passive transport of macromolecules in growing nerve processes was analyzed quantitatively by measuring the rate diffusion fluorescently labeled molecules injected into soma cultured Xenopus neurons. We found that globular proteins neurite's cytoplasm about five times slower than aqueous solution, a considerably higher those inferred from previous studies on non-neuronal cells. The dependence coefficient, D, size diffusing examined diffusional spread dextrans over wide range molecular...
Nerve growth depends on the delivery of cell body–synthesized material to growing neuronal processes. The cellular mechanisms that determine topology new membrane addition axon are not known. Here we describe a technique visualize transport and sites exocytosis body– derived vesicles in axons. We found Xenopus embryo neurons culture, body–derived were rapidly transported all way down cone region, where they fused with plasma membrane. Suppression microtubule (MT) dynamic instability did...
The type section of the Oligocene to lower Miocene Maikop Group, considered main source rock in eastern Paratethys, has been studied using geochemical proxies gain insights into depositional setting and hydrocarbon potential. Group at is approximately 600 m (2000 ft) thick. Deposition commenced after a major late Eocene sea level drop subsequent early rise. composed mainly carbonate-free pelitic rocks. Calcareous rocks are limited succession, including Polbian Bed that forms basin-wide...
Abstract The surface structure, biocompatibility, textural, and adhesive properties of calcium hydrogels derived from 1, 2, 4% solutions apple pectin were examined in this study. An increase the concentration was shown to improve their stability toward elastic plastic deformation. elasticity hydrogels, measured as Young's modulus, ranged 6 100 kPa. mechanical correspond those soft tissues. characterization roughness terms profile (Ra) root‐mean‐square deviation (Rq) indicated an increased...
Nerve growth requires addition of new plasma membrane material, which is generally believed to occur at the cone. Local incorporation a fluorescent lipid analog into fast-growing Xenopus neurites revealed an anterograde bulk flow that correlated with neurite elongation. The rate depended on position labeled segment along neurite, increasing distance from soma. This result suggests in growing added not cone but cell body and neurite.
The antioxidant properties of vegetable pectin fractions against intraluminal reactive oxygen species were elucidated in vitro conjunction with their structural features. isolated using a simulated gastric fluid (pH 1.5, pepsin 0.5 g/L, 37°C, 4 h) from fresh white cabbage, carrot, onion, and sweet pepper. fraction onion was found to inhibit the production superoxide radicals by inhibiting xanthine oxidase. high molecular weight large number galactose residues its side chains appeared...
The discrepancy between biological and social rhythms known as jetlag (SJL) is common in modern society has a range of negative consequences for cognitive functioning, well-being health. Social typical people with late chronotypes. As shown earlier, the prevalence individuals chronotype higher among residents high latitudes. Therefore, rate detection SJL should be expected North. In this study we assessed 62 young inhabitants European North Russia (the Komi Republic), relationship SJL,...
Background. The COVID-19 lockdown has had a significant impact on mental health. Patients with eating disorders (ED) have been particularly vulnerable. Aims. (1) To explore changes in eating-related symptoms and general psychopathology during patients an ED from various European Asian countries; (2) to assess differences related diagnostic subtypes, age, geography. Methods. sample comprised 829 participants, diagnosed according DSM-5 criteria specialized units Europe Asia. Participants were...
This study aimed to investigate the influence of kappa (κ)-carrageenan on initial stages foreign body response against pectin gel. Pectin-carrageenan (P-Car) gel beads were prepared from apple and κ-carrageenan using gelling with calcium ions. The inclusion 0.5% (Car0.5) in 1.5 (P1.5) 2% (P2) formulations decreased strength by 2.5 times. Car0.5 was found increase swelling P2 cell culture medium. adsorbed 30–42 mg/g bovine serum albumin (BSA) depending pH. P2-Car0.2, P2-Car0.5, P1.5-Car0.5...
The aim of the study was to develop ink enriched with a high content lupine callus tissue (CT) suitable for 3D printing.
