Background Reducing sedentary behavior (SB) in individuals with chronic obstructive pulmonary disease (COPD) is being increasingly recognized as a novel health target. Understanding healthcare professionals (HCPs) behavior that influences a reduction in SB in this population could facilitate achieving this target. Objective To explore the determinants of behavior related to HCPs targeting a reduction in SB in people with COPD. Methods We used a qualitative semi-structured interview approach informed by the Theoretical Domains Framework (TDF). this website Sixteen HCPs were interviewed. Interview transcripts were mapped against the relevant TDF domain(s) and then higher order themes were generated. Results Directed content analysis resulted in mapping 949 quotes to the TDF domains with environmental context and resources being the most coded domain. Three higher order themes were identified 1) HCPs need more knowledge on reducing SB; 2) Strategies suggested to include in pulmonary rehabilitation (PR) to reduce SB; and 3) Barriers to adding SB to PR. Domains of environmental context and resources, knowledge, social/professional role and identity, reinforcement, social influences, skills and beliefs about capabilities were relevant to the study population to reduce SB in people with COPD. Conclusion Knowledge of SB varied across participants. This study provided information on potential behavioral targets for future interventions that involve HCPs and aim to reduce SB among people with COPD.Environmental fitness is an essential component of animal survival. Fitness is achieved through responsive physiological plasticity of tissues across the entire body, and particularly in the nervous system. At the molecular level, neural plasticity is mediated via gene-environmental interactions whereby developmental cues and experience dependent input adapt neuronal function to ever changing demands. To this end, neuronal gene regulation must be coupled to changes in neural activity. Seminal discoveries of the 20th century demonstrated neural activity modifies gene expression through calcium-dependent gene transcription. Building on this model, recent work over the last two decades shows that mRNA products of transcriptional programming continue to be regulated in the neuron through the activity-dependent post-transcriptional action of microRNAs (miRNAs). miRNAs are special post-transcriptional regulators that can tune gene expression within the spatial and temporal requirements of synaptic compartments. This mode of gene regulation has proven to be essential for synaptic function and plasticity as miRNA loss of function is highly associated with neural disease. In this review we will discuss current perspective on the link between presynaptic plasticity and miRNA biogenesis in the neuron.Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the most cryptic pandemic outbreak of the 21st century, has gripped more than 1.8 million people to death and infected almost eighty six million. As it is a new variant of SARS, there is no approved drug or vaccine available against this virus. This study aims to predict some promising cytotoxic T lymphocyte epitopes in the SARS-CoV-2 proteome utilizing immunoinformatic approaches. Firstly, we identified 21 epitopes from 7 different proteins of SARS-CoV-2 inducing immune response and checked for allergenicity and conservancy. Based on these factors, we selected the top three epitopes, namely KAYNVTQAF, ATSRTLSYY, and LTALRLCAY showing functional interactions with the maximum number of MHC alleles and no allergenicity. Secondly, the 3D model of selected epitopes and HLA-A*2902 were built and Molecular Docking simulation was performed. Most interestingly, the best two epitopes predicted by docking are part of two different structural proteins of SARS-CoV-2, namely Membrane Glycoprotein (ATSRTLSYY) and Nucleocapsid Phosphoprotein (KAYNVTQAF), which are generally target of choice for vaccine designing. Upon Molecular Docking, interactions between selected epitopes and HLA-A*2902 were further validated by 50 ns Molecular Dynamics (MD) simulation. Analysis of RMSD, Rg, SASA, number of hydrogen bonds, RMSF, MM-PBSA, PCA, and DCCM from MD suggested that ATSRTLSYY is the most stable and promising epitope than KAYNVTQAF epitope. Moreover, we also identified B-cell epitopes for each of the antigenic proteins of SARS CoV-2. Findings of our work will be a good resource for wet lab experiments and will lessen the timeline for vaccine construction.Communicated by Ramaswamy H. Sarma.This study investigated how the difference in the timing of the extension of the joints of the lower limbs during take-off affects the backstroke start performance. Eleven backstroke swimmers performed three lower-limb joint extension sequences of backstroke start knee extension after hip extension (KAH), simultaneous hip and knee extension (SHK), and knee extension before hip extension (KBH). The shortest 5-m time was performed at KAH (1.90 ± 0.26 s), followed by a performance at SHK (2.12 ± 0.52 s) and KBH (2.47 ± 0.61 s). The greater trochanter (GT) vertical positions at toe-off were higher at KAH and SHK than at KBH. KAH had a shorter entry range, defined as the horizontal distance from the fingertip (FT) to the GT entry in the water, than KBH and SHK. A positive correlation was noted between the entry range and the 5-m time at KAH (r = 0.79). In addition, a negative correlation was observed between the GT vertical position at toe-off and the entry range at KAH (r = -0.65). The results suggested that KAH makes it easier to take the arched-back posture after toe-off, allowing the performance of a hole-entry technique that reduces the entry range and the 5-m time.Background Neurasthenia was one of the most commonly diagnosed disorders in the later years of the 19th century. Its most widely used treatment, known as the Rest Cure, relied heavily on physical therapies, but little is known about the practitioners who administered the treatment. In this paper, I argue that the nurse-masseuses who delivered the massage and electricity so vital to the success of the Rest Cure, used the opportunity to develop approaches to treatment that would form the backbone of the physiotherapy profession in England after 1894. Methods Extensive primary and secondary texts were drawn from a wide range of sources and critically reviewed. Findings This study argues that the management of neurasthenic cases in the 1880s and 90s created the conditions necessary for the development of the profession's relationship with medicine and the establishment of new practice roles for women, and that these would play an important role in shaping the physiotherapy profession in Britain after 1894. Read through the critical sociological writings of Magali Sarfatti Larson and Anne Witz, I argue that the work of the nurse-masseuses can be seen as a complex gendered negotiation between the need to be deferential to the dominant male medical profession; distinct from emerging notions of the angelic, motherly nurse; obedient, technically competent and safe. The creation of a space in the clinic room for a third practitioner who could deliver a different form of care to the doctor or the nurse, established an approach to practice that physiotherapists would later adopt almost without amendment. Discussion I argue that this approach owes much to the work done by nurse-massueses who established and tested its principles in treating cases of neurasthenia.Walking and running at different speeds are common in daily life. This study investigated 6 degrees of freedom (DOF) kinematics of normal knees of Chinese during walking and running. Forty healthy participants were investigated in 4 conditions comfortable walking, normal walking, slow running and ordinary running. The range of motion (ROM) and peak values in 6 DOF kinematics were analysed. As the speed increased, a general increase in flexion, lateral and proximal translations occurred. Significant increases of ROM in flexion/extension, axial rotation and medial/lateral translations were observed. The ROM of adduction/abduction, anterior/posterior and proximal/distal translations were greatest during normal walking. The maximum and minimum flexion/extension, maximum internal rotation and tibial lateral translations increased with the increase of speed. The maximum and minimum tibial proximal translations in running were found being greater than walking. A phenomenon between walking and running was observed both tibial proximal/distal and medial/lateral translations increased when changed from walking to running. Non-linear transition exists in 6 DOF kinematics during walking to running. Discoveries in this study may have potential clinical values to serve as references of normal walking and running in the management of knee injury and knee rehabilitation.Nucleotide modification in RNA controls a bevy of biological processes, including RNA degradation, gene expression, and gene editing. In turn, misregulation of modified nucleotides is associated with a host of chronic diseases and disorders. However, the molecular mechanisms driving these processes remain poorly understood. To partially address this knowledge gap, we used alchemical and temperature replica exchange molecular dynamics (TREMD) simulations on an RNA duplex and an analogous hairpin to probe the structural effects of modified and/or mutant nucleotides. The simulations successfully predict the modification/mutation-induced relative free energy change for complementary duplex formation, and structural analyses highlight mechanisms driving stability changes. Furthermore, TREMD simulations for a hairpin-forming RNA with and without modification provide reliable estimations of the energy landscape. Illuminating the impact of methylated and/or mutated nucleotides on the structure-function relationship and the folding energy landscape, the simulations provide insights into modification-induced alterations to the folding mechanics of the hairpin. The results here may be biologically significant as hairpins are widespread structure motifs that play critical roles in gene expression and regulation. Specifically, the tetraloop of the probed hairpin is phylogenetically abundant, and the stem mirrors a miRNA seed region whose modification has been implicated in epilepsy pathogenesis.Heat stress (HS) leads to substantial economic loss of dairy industry each year. The negative effect of HS in dairy cows is becoming one of the more urgent issue due to accelerating side-effects of global warming. Various genes are involved in HS response but the information about the role of noncoding RNAs, especially circular RNAs (circRNAs) is largely unknown. In our study, we aimed to investigate the different expression profile of circRNAs between HS and Non-heat-stressed condition (NC) of Chinese Holstein cow's mammary gland. CircRNAs were identified using RNA sequencing and bioinformatics analysis. In total, 37405 circRNAs were detected and 95 were differentially expressed (DE), including 15 downregulated and 80 upregulated circRNAs in HS group compared to NC. Eight circRNAs were randomly selected to verify the RNA sequencing result. Further, Sanger sequencing validated the backsplicing site of the eight circRNAs. Moreover, results obtained from the Quantitative real time PCR (qRT-PCR) showed consistent expression trend with that of RNA sequencing.
