Finally, how these changes could represent signs of physiological adaptation in successful aging was discussed.
Although pulmonary rehabilitation (PR) improves function in people with chronic obstructive pulmonary disease (COPD), a community-based exercise program may be necessary to maintain functional capacity. We aimed to determine the effectiveness of a post-rehabilitation, community-based maintenance program on exercise tolerance, functional capacity and quality of life.

Patients with COPD who completed PR were randomized to receive a community-based maintenance program (intervention) or usual care (control). The primary outcome was 6-min walk distance (6MWD), measured immediately post-PR, 6 months and 12 months later. Secondary outcomes included self-reported functional capacity, health-related quality of life, self-efficacy, program cost, and lower extremity muscle strength.

Ninety-seven patients (69±9 years) were enrolled. There was a non-significant trend of an intervention effect on 6MWD over time (β=42, 95% CI 0.06 to 83.93, p=0.053). There was no significant impact of group on any of the secondary outcomes. Restricting the analysis to those who attended ≥50% of the exercise sessions showed a significant intervention effect for 6MWD (β=69.19, 95% CI=10.16 to 128.22, p=0.03). The cost of participating in the community maintenance program for the intervention group was $374.77 (SD 142.12) and membership renewal was highest at community centres offering twice weekly, supervised exercise classes.

A post rehabilitation, community-based exercise program, will maintain exercise capacity in people with COPD who attend at least 50% of available sessions over one year. An increased focus on factors that determine adherence would help inform improvements in maintenance program design.

Anti-N-methyl-d-aspartate receptor (NMDAR) and anti-voltage-gated potassium channel (VGKC) encephalitis are the commonest antibody-associated autoimmune encephalitides (AIE). Acute clinical features have been well-described, but data on the role of radiological findings in diagnosis and prognosis of AIE are limited.

Anti-NMDAR and anti-VGKC encephalitis patients from the National Neuroscience Institute were identified. LY2780301 inhibitor We compared clinical and paraclinical features, at acute presentation and on follow-up between and within groups.

Twenty-six anti-NMDAR and 11 anti-VGKC encephalitis patients were reviewed. At acute presentation, dysautonomia (57.7%) and impairment of consciousness (84.6%) occurred exclusively in anti-NMDAR encephalitis. Cerebrospinal fluid pleocytosis was more common in anti-NMDAR encephalitis (88.5% vs 20.0%, p=0.003), while ictal electroencephalography abnormalities were more frequent in anti-VGKC encephalitis (11.5% vs 45.5%, p=0.022). On acute imaging, leptomeningeal enhancement was in early diagnosis and prognostication in suspected AIE. Leptomeningeal enhancement in anti-NMDAR encephalitis and hippocampal lesions in anti-VGKC encephalitis, together with typical clinical features, may allow distinction between these antibody subtypes, and specific abnormal imaging features in anti-VGKC encephalitis may be used as a prognostic marker.Understanding allosteric regulation of proteins is fundamental to our study of protein structure and function. Moreover, allosteric binding pockets have become a major target of drug discovery efforts in recent years. However, even though the function of almost every protein can be influenced by allostery, it remains a challenge to discover, rationalise and validate putative allosteric binding pockets. This review examines how the discovery and analysis of putative allosteric binding sites have been influenced by the availability of centralised facilities for crystallographic fragment screening, along with newly developed computational methods for modelling low occupancy features. We discuss the experimental parameters required for success, and how new methods could influence the field in the future. Finally, we reflect on the general problem of how to translate these findings into actual ligand development programs.UDP-glucose 4-epimerase (GalE) catalyzes the interconversion of UDP-glucose (UDP-Glc) and UDP-galactose (UDP-Gal) and/or the interconversion of UDP-N-acetylglucosamine (UDP-GlcNAc) and UDP-N-acetylgalactosamine (UDP-GalNAc) in sugar metabolism. GalEs belong to the short-chain dehydrogenase/reductase superfamily, use a conserved 'transient keto intermediate' mechanism and have variable substrate specificity. GalEs have been classified into three groups based on substrate specificity group 1 prefers UDP-Glc/Gal, group 3 prefers UDP-GlcNAc/GalNAc, and group 2 has comparable activities for both types of the substrates. The phylogenetic relationship and structural basis for the specificities of GalEs revealed possible molecular evolution of UDP-hexose 4-epimerases in various organisms. Based on the recent advances in studies on GalEs and related enzymes, an updated view of their evolutional diversification is presented.
Humans are highly social creatures who use others' movements to evaluate their social competencies. Smooth movement specifically signals an attractive, trustworthy or competent person. Those with Developmental Coordination Disorder (DCD), have peer relationship difficulties and lower sociometric preference scores. However, the relationship of perception of poor movement coordination to stereotyping has not been directly demonstrated.

We aimed to describe typically developing individuals' social stereotyping of individuals with and without DCD from minimal visual cues.

3D motion capture tracked the movement of four 'targets' (two adult males with DCD and two male controls) in a variety of everyday scenarios. Kinematic footage of the target's movements was presented as a point-light-display to 319 typically developing adults who used The Rating Scale of Social Competence to report perceptions of the target's social competencies.

Targets with DCD were rated as having significantly lower social competenceyping to a new applied domain, confirming the minimal cues needed to initiate stereotyping of the competencies of others.Bacteria belonging to the genus Paraburkholderia are capable of establishing symbiotic relationships with plants belonging to the Fabaceae (=Leguminosae) family and fixing the atmospheric nitrogen in specialized structures in the roots called nodules, in a process known as biological nitrogen fixation (BNF). In the nodulation and BNF processes several bacterial symbiotic genes are involved, but the relations between symbiotic, core genes and host specificity are still poorly studied and understood in Paraburkholderia. In this study, eight strains of nodulating nitrogen-fixing Paraburkholderia isolated in Brazil, together with described species and other reference strains were used to infer the relatedness between core (16S rDNA, recA) and symbiotic (nod, nif, fix) genes. The diversity of genes involved in the nodulation (nodAC) and nitrogen fixation (nifH) abilities was investigated. Only two groups, one containing three Paraburkholderia species symbionts of Mimosa, and another one with P. ribeironis strains presented similar phylogenetic patterns in the analysis of core and symbiotic genes. In three other groups events of horizontal gene transfer of symbiotic genes were detected. Paraburkholderia strains with available genomes were used in the complementary analysis of nifHDK and fixABC and confirmed well-defined phylogenetic positions of symbiotic genes. In all analyses of nod, nif and fix genes the strains were distributed into five clades with high bootstrap support, allowing the proposal of five symbiovars in nodulating nitrogen-fixing Paraburkholderia, designated as mimosae, africana, tropicalis, atlantica and piptadeniae. Phylogenetic inferences within each symbiovar are discussed.The COVID-19 pandemic has placed unprecedented global demand on laboratory supplies required for testing. Sample pooling has been investigated by laboratories as a strategy to preserve testing capacity. We evaluate the performance of Cepheid Xpert® Xpress SARS-CoV-2 RT-PCR assay for testing samples in pools of 4 and 6. Clinical samples containing SARS-CoV-2, and confirmed negative clinical samples were used to create sample pools. Clinical samples had 'neat' Xpert® E gene cycle threshold values ranging between 20 and 28 and all were detected qualitatively when contained in pools of 4 or 6 samples. For these samples, pooling had a median change in cycle threshold value of 2.0 in pools of 4, and of 2.9 in pools of 6. With the use of Cepheid Xpert® Xpress SARS-CoV-2 RT-PCR assay, pooling of 4 or 6 samples may be an effective strategy to increase testing capacity.The 14C analysis of permanent teeth employing nuclear techniques has a direct application in Forensic Sciences since teeth are the hardest part of the human body and can survive natural decay or extreme conditions. After the first Accelerator Mass Spectrometry Laboratory AMS-LEMA at UNAM, our research group is interested in reproducing 14C analysis on teeth as other countries to estimate age in the Mexican population samples. One of the main goals of this exploratory study is to know the best methodology considering relevant biological factors based on differences in tissues (enamel and dentin) that allows us to know the year of birth through the 14C concentration comparing the yield between 14C analyses from carbonate in enamel and collagen in dentin. In this study, Accelerator Mass Spectrometry (AMS) has been performed in 22 contemporary teeth samples (each one donated from 1 different adult), participating 22 individuals by informed consent to enable a new tool and improve forensic practices in Mexico. Carbon is extracted, converted to graphite, and pressed into a cathode. The sample is taken to an AMS system, where carbon isotopes are separated, counted, and the 14C/12C and 13C/12C ratios determined. Our results for standards and teeth samples from Mexican people are in good agreement with the expected values; they are also useful to set up the best conditions for studies in dentin and enamel. However, this is a destructive technique for dental organs; it is not suitable for individuals born previous 1950. New challenges in sample preparation processes are to be solved to take advantage of the nuclear techniques developed in the last 50 years and make new contributions to society.High-energy electron treatment procedures in radiotherapy pose a potential iatrogenic cancer risk as well as a critical health risk to patients with cardiac implantable electronic devices due to the generation of secondary neutrons in the linac head, the treatment room, and the patient. It may be argued that the neutron production from photons is well characterized, but the same is not true for electrons. Therefore, to assess the risk involved in an electron treatment, one must determine the neutron flux spectrum generated by the treatment procedure. The neutron spectrum depends on the treatment parameters used and therefore it is crucial to study its dependence on these parameters. In this work, eight experiments were devised to analyze how eight electron treatment parameters impacted the neutron spectrum. The parameters we considered were the electron beam energy, location of measurement, cutout size, collimator size, applicator size, collimator angle, choice of treatment room, and the presence or absence of a solid water phantom.
