Overall, these findings emphasize the importance of inflammation in age-related hepatic vasculo-epithelial alterations and highlight the utility of qLIM in studying age-related effects in organ pathophysiology.Duchenne muscular dystrophy (DMD) is an inherited muscle wasting disease. Metabolic impairments and oxidative stress are major secondary mechanisms that severely worsen muscle function in DMD. Here, we sought to determine whether germline reduction or ablation of sarcolipin (SLN), an inhibitor of sarco/endoplasmic reticulum (SR) Ca2+ ATPase (SERCA), improves muscle metabolism and ameliorates muscle pathology in the mdx mouse model of DMD. Glucose and insulin tolerance tests show that glucose clearance rate and insulin sensitivity were improved in the SLN haploinsufficient mdx (mdxsln+/-) and SLN-deficient mdx (mdxsln-/-) mice. The histopathological analysis shows that fibrosis and necrosis were significantly reduced in muscles of mdxsln+/- and mdxsln-/- mice. SR Ca2+ uptake, mitochondrial complex protein levels, complex activities, mitochondrial Ca2+ uptake and release, and mitochondrial metabolism were significantly improved, and lipid peroxidation and protein carbonylation were reduced in the muscles of mdxsln+/- and mdxsln-/- mice. These data demonstrate that reduction or ablation of SLN expression can improve muscle metabolism, reduce oxidative stress, decrease muscle pathology, and protects the mdx mice from glucose intolerance.In vivo administration of dopamine (DA) receptor (DR)-related drugs modulate gastric pepsinogen secretion. However, DRs on gastric pepsinogen-secreting chief cells and DA D2 receptor (D2R) on somatostatin-secreting D cells were subsequently acquired. In this study, we aimed to further investigate the local effect of DA on gastric pepsinogen secretion through DRs expressed on chief cells or potential D2Rs expressed on D cells. To elucidate the modulation of DRs in gastric pepsinogen secretion, immunofluorescence staining, ex vivo incubation of gastric mucosa isolated from normal and D2R-/- mice were conducted, accompanied by measurements of pepsinogen or somatostatin levels using biochemical assays or enzyme-linked immunosorbent assays. D1R, D2R, and D5R-immunoreactivity (IR) were observed on chief cells in mouse gastric mucosa. D2R-IR was widely distributed on D cells from the corpus to the antrum. Ex vivo incubation results showed that DA and the D1-like receptor agonist SKF38393 increased pepsinogen secretion, which was blocked by the D1-like receptor antagonist SCH23390. However, D2-like receptor agonist quinpirole also significantly increased pepsinogen secretion, and D2-like receptor antagonist sulpiride blocked the promotion of DA. Besides, D2-like receptors exerted an inhibitory effect on somatostatin secretion, in contrast to their effect on pepsinogen secretion. Furthermore, D2R-/- mice showed much lower basal pepsinogen secretion but significantly increased somatostatin release and an increased number of D cells in gastric mucosa. Only SKF38393, not quinpirole, increased pepsinogen secretion in D2R-/- mice. DA promotes gastric pepsinogen secretion directly through D1-like receptors on chief cells and indirectly through D2R-mediated suppression of somatostatin release.Skilled movements result from a mixture of feedforward and feedback mechanisms conceptualized by internal models. These mechanisms subserve both motor execution and motor imagery. Current research suggests that imagery allows updating feedforward mechanisms, leading to better performance in familiar contexts. Does this still hold in radically new contexts? Here, we test this ability by asking participants to imagine swinging arm movements around shoulder in normal gravity condition and in microgravity in which studies showed that movements slow down. We timed several cycles of actual and imagined arm pendular movements in three groups of subjects during parabolic flight campaign. The first, control, group remained on the ground. The second group was exposed to microgravity but did not imagine movements inflight. The third group was exposed to microgravity and imagined movements inflight. All groups performed and imagined the movements before and after the flight. We predicted that a mere exposure to microgravually executing a task is not necessary to update graviception.Purpose Evidence is scarce regarding the associations of romantic orientation with mental health and personality. The aims of the present study, therefore, were to examine psychological distress among homoromantic, biromantic, and heteroromantic adults and to investigate how personality dimensions influence their distress. Methods A cross-sectional survey study was conducted between August 2018 and January 2021. Psychological distress, personality, and romantic orientation were assessed with the 6-item Kessler Psychological Distress Scale (K6), the Ten-Item Personality Inventory (TIPI), and a question about romantic orientation, respectively, in a web-based survey distributed to 11,922 participants. Saliva samples were collected for DNA extraction. After excluding those who did not cluster with Japanese ancestry and those whose genotypic sex did not match their reported sex, 11,662 individuals were included in further analyses. Results The prevalence of being homoromantic or biromantic was 1.0% and 2.0% for females and 1.5% and 1.2% for males, respectively. Homoromantic males, but not females, had significantly higher K6 scores than their heteroromantic counterparts. selleck chemicals llc Both male and female biromantic participants had significantly higher K6 scores than their heteroromantic counterparts. Furthermore, a significant association was found between romantic orientation and TIPI scores. Accounting for personality profiles did not alter the observed association between romantic orientation and psychological distress. Conclusion Biromantic adults and homoromantic male adults of genetically confirmed Japanese ancestry living in Japan experienced higher psychological distress than heteroromantic individuals. The mental health disparities of the romantic minority individuals were irrespective of their personality profiles, suggesting the involvement of other factors such as minority stress in Japan.Background Serious games (SGs) have been proposed as a type of technology-enhanced simulation that may provide nursing students with an opportunity to practice their clinical reasoning and decision-making skills in a realistic and safe environment. Materials and Methods The aim of this study is to determine the effect of serious play on nursing students' self-confidence (SC) and anxiety in clinical decision making. The randomized controlled trial evaluated the efficacy of SGs for undergraduate nursing students using pre- and posttests. The study was conducted during nursing students' clinical practice and teaching. All undergraduate nursing students (n = 120) attending internal medicine nursing lesson were approached. Sixty students out of 120 answered the questionnaires at both baseline and follow-up (30 in the experimental group [EG] and 30 in the control group). The students answered the questionnaire after taking the first clinical practice, taking the endocrine course. In the 1 week, the EG played the game and both groups returned to clinical practice. Questionnaire data were collected after clinical application. Results SC and two subdimensions, using the information in hand to determine the problem, and knowing and taking action, were improved in the intervention group and a significant interaction effect was found for changes over time between the two groups. Anxiety scores between groups were not statistically significant differences. Conclusions Nursing professional educators can adopt SGs to improve cognitive and attention skills, strengthen judgment, require making time efficient, practice making safe decisions, and encourage the exploration of decision.Objective The aim of this study was to evaluate and compare the effects of extracorporeal shock wave therapy (ESWT) and high-intensity laser therapy (HILT), as outpatient physical therapy modalities, on knee osteoarthritis (KOA) patients. Materials and methods The treatment program was completed by 40 individuals with stage II KOA (according to Kellgren and Lawrence) who were randomly allocated to one of two groups. They have had more than grade 3 pain on the visual analog scale (VAS) during activities for the last 3 months, with body-mass index less than 30 and no history of knee operation, fracture, cancer, or other neuromuscular or musculoskeletal diseases that may affect study results. The ESWT group (n = 20, mean age = 40.12 ± 9.45 years) received ESWT, 0.05 mJ/mm2, one session/week for 4 weeks, and the HILT group (n = 20, mean age = 46.62 ± 8.68 years) received HILT, 1500 mJ/cm2 in each session, three sessions/week for 4 weeks. Both groups received conservative physical therapy programs. Before and after 4 weeks of intervention, pain, physical function, and disability were assessed using a VAS, 6-min walking test, and the Western Ontario and McMaster Universities Osteoarthritis Index. Results When the pre- and post-treatment mean values of dependent variables of both groups were compared, there were statistically significant improvements in both groups. Significant differences in the measured variables were also discovered in favor of the HILT group compared with the ESWT group. Conclusions HILT showed a superior effect compared with ESWT on pain, physical function, and disability in chronic KOA patients. Pan African Clinical Trials Registry number PACTR202007638955907.Lyme borreliosis is the most common vector-borne disease in the Northern Hemisphere, caused by spirochetes belonging to the Borrelia burgdorferi sensu lato species complex, which are transmitted by ixodid ticks. B. burgdorferi sensu lato species produce a family of proteins on the linear plasmid 54 (PFam54), some of which confer the functions of cell adhesion and inactivation of complement, the first line of host defense. However, the impact of PFam54 in promoting B. burgdorferi sensu lato pathogenesis remains unclear because of the hurdles to simultaneously knock out all PFam54 proteins in a spirochete. Here, we describe two Borrelia bavariensis strains, PBN and PNi, isolated from patients naturally lacking PFam54 but maintaining the rest of the genome with greater than 95% identity to the reference B. bavariensis strain, PBi. We found that PBN and PNi less efficiently survive in human serum than PBi. Such defects were restored by introducing two B. bavariensis PFam54 recombinant proteins, BGA66 and BGA71, c increased susceptibility to human serum, which can be rescued in the presence of two PFam54 recombinant proteins. However, both isolates remain infectious to mice after intradermal inoculation, suggesting the nonessential role of PFam54 during the long-term, but may differ slightly in the colonization of specific tissues. Furthermore, these isolates show high genomic similarity to type strain PBi (>95%) and could be used in future studies investigating the role of each PFam54 protein in Lyme borreliosis pathogenesis.

Palliative care (PC) plays an established role in improving outcomes in patients with solid tumors, yet these services are underutilized in hematologic malignancies (HMs). We reviewed records of hospitalized patients with active HM to determine associations between PC consultation and length of stay, intensive care unit stay, 30-day readmission, and 6-month mortality compared with those who were not seen by PC.

We reviewed all oncology admissions at our institution between 2013 and 2019 and included patients with HM actively on treatment, stratified by those seen by PC to controls not seen by PC. Groups were compared using Wilcoxon rank-sum, chi-square, and Fisher's exact tests on the basis of the type and distribution of data. Multiple logistic regression models with stepwise variable selection methods were used to find predictors of outcomes.

Three thousand six hundred fifty-four admissions were reviewed, among which 370 unique patients with HM were included. Among these, 102 (28%) patients saw PC, whereas the remaining 268 were controls with similar comorbidities.
