Most of the strains had Cas1/Cas4 fusion proteins. Pseudopropionibacterium propionicum strains had two types I-U and one of the CRISPR loci had csx17 cas genes. Common phage invaders were Propionibacterium phage E6, G4, E1, Anatole, and Doucette. The BLSM62 similarity score of all Cas1 sequences was 48.4% while the pairwise identity of repeat sequences was 48.7%. Common insertion sequences were ISL3, IS3, IS30. The diversity analysis of the CRISPR/Cas system in the genus Propionibacterium provided a new perspective for determining the role of the CRISPR-Cas system in the evolution of new genera.

Both hip fracture and bone mineral density (BMD) decline on the non-fractured side are more likely to occur within 1year. However, there are no longitudinal study reports on the factors associated with BMD maintenance or improvement within the first year after hip fracture. This study aimed to investigate the factors influencing the neck BMD maintenance or improvement in patients with hip fractures from within 2weeks-6months after surgery.

Patients were hip fracture after surgery and were divided into two groups Among neck BMD changes (6months minus 2weeks after surgery) were calculated. Based on among neck BMD change, patients were classified into the BMD maintenance or improvement (change ≥ 0) and the BMD decrease groups (change < 0). Propensity score matching was performed to adjust for confounding factors. To predict the factors affecting neck BMD, hierarchical logistic regression analysis was performed. The dependent variable was the BMD maintenance or improvement group and the BMD decrease group. The independent variables were basic and medical information, and physical functions.

The hierarchical logistic regression analysis results showed that movement control during one-leg standing affected femoral neck BMD independently from age, sex. The odds ratio for movement control during one-leg standing was 8.22. The discrimination rate of the model was 69.7%.

This study suggested that adequate movement control during one-leg standing is important to maintain or improve neck BMD.

Osteoarthritis is a common joint disease that causes destruction of articular cartilage and severe inflammation surrounding knee and hip joints. However, to date, effective therapeutic reagents for osteoarthritis have not been developed because the underlying molecular mechanisms are complex. Recent genetic findings suggest that a Wnt antagonist, frizzled-related protein B (FRZB), is a potential therapeutic target for osteoarthritis. Therefore, this study aimed to examine the transcriptional regulation of FRZB in chondrocytes.

Frzb/FRZB expression was assessed by RT-qPCR analyses in murine articular chondrocytes and SW1353 chondrocyte cell line. T-DM1 cell line Overexpression and knockdown experiments were performed using adenovirus and lentivirus, respectively. Luciferase-reporter and chromatin immunoprecipitation assays were performed for determining transcriptional regulation. Protein-protein interaction was determined by co-immunoprecipitation analysis.

Frzb was highly expressed in cartilages, especially within articular chondrocytes. Interleukin-1α markedly reduced Frzb expression in articular chondrocytes in association with cartilage destruction and increases in ADAM metallopeptidase with thrombospondin type 1 motif (Adamts) 4 and Adamts5 expression. Bone morphogenetic protein 2 (BMP2) increased FRZB expression in SW1353 cells through Smad signaling. Osterix and msh homeobox 2 (Msx2), both of which function as downstream transcription factors of BMP2, induced FRZB expression and upregulated its promoter activity. Co-immunoprecipitation results showed a physical interaction between Osterix and Msx2. Knockdown of either Osterix or Msx2 inhibited BMP2-dependent FRZB expression. Chromatin immunoprecipitation indicated a direct association of Osterix and Msx2 with the FRZB gene promoter.

These results suggest that BMP2 regulates FRZB expression through Osterix and Msx2.

Various complications related to the prosthesis, such as implant loosening and stress shielding phenomenon, could develop after prosthetic replacement of the radial head. Stress shielding is known to occur around rigidly fixed implants. The purpose of this study was to evaluate the clinical influence and causative factors of the stress shielding phenomenon after radial head arthroplasty (RHA).

Clinical records and radiographs of 56 patients with unreconstructable radial head fractures who received radial head replacement between 2009 and 2019 were reviewed. Exclusion criteria were infection, loosening, and follow-up of less than 24months. After exclusion, 35 patients were enrolled. Patients were divided into two groups an anatomical press-fit group (Anatomical Radial Head System; Acumed, Hillsboro, OR, USA) and a round bipolar cemented group (RHS; Tornier, Montbonnot Saint-Martin, France). Stress shielding around the prosthesis was assessed in the serial radiological examination. Clinical results were assreatment Study.

Retrospective Cohort Comparison; Treatment Study.

Traumatic facet dislocations in the subaxial cervical spine, also known as locked facets, are commonly associated with neurological deficits. The fear of the presence of an associated traumatic disc herniation and consequent neurological worsening usually causes a delay in the spinal realignment. This study's aim is an analysis of safety and efficacy when treating acute cervical traumatic facet dislocations using cranial-cervical traction or posterior open reduction and fixation in the presence of disc herniations.

Inclusion criteria addressed the following patient groups (1) MRI diagnosis of traumatic cervical facet dislocations with disc herniation, (2) intervention either cranial-cervical traction or posterior open reduction and fixation, (4) neurological outcomes after treatment, (5) adult 18 plus years of age, (6) sample sizes greater than 20 patients, (7) English language publication. The following databases and search tools were analyzed MEDLINE (PubMed), Cochrane Central Register of Controlled Triil prospective and well-designed studies are performed.Mood disorders (MD) are often associated with a higher incidence of suicidal behavior, especially in adolescent patients. However, the mechanisms by which depression affects suicide attempts in adolescents with MD remain poorly elucidated. Therefore, the purpose of this study was to determine the incidence, risk factors, and clinical correlates of suicide attempts in Chinese adolescent patients with MD, as well as the inter-relationship between depressive symptoms, rumination, and suicide attempts, and the role of rumination in mediating depression and suicide attempts. A total of 331 MD adolescent patients aged 11 ~ 18 years were recruited from a psychiatric hospital. Suicide attempts were assessed with the MINI Suicide Scale. Depressed symptoms were measured with the Patient Health Questionnaire-9 (PHQ-9). To assess rumination, we used the 21-item Chinese version of the Ruminative Responses Scale (RRS). Overall, the percentage of suicide attempts among MD adolescents was 51.96%, with a higher percentage of females (58.62%) than males (36.36%). Compared to non-suicide attempters, suicide attempters had higher scores on PHQ-9, RRS, depression-related, brooding, and reflective pondering. Gender and RRS were independently associated with suicide attempts. Rumination played a fully mediating role between depression and suicide attempts. In addition, the mediating effect of depression between rumination and suicide attempts was not significant. The incidence of suicide attempts was higher in MD adolescents than in general adolescents. Gender and rumination were associated with suicide attempts in MD adolescents. Moreover, rumination mediated the correlation between depressive symptoms and suicide attempts, suggesting that rumination may be an important intervention component for clinical staff to prevent suicidal behavior in adolescents with MD.

The cysteine

(C674) thiol of sarcoplasmic/endoplasmic reticulum Ca

ATPase 2 is easily and irreversibly oxidized under atherosclerotic conditions. However, the contribution of the C674 thiol redox status in the development of atherosclerosis remains unclear. Our goal was to elucidate the possible mechanism involved.

Heterozygous SERCA2 C674S knock-in mice in which half of the C674 was substituted by serine (S674) were used to mimic the removal of the reactive C674 thiol, which occurs under pathological conditions. Bone marrow-derived macrophages (BMDMs) and cardiac endothelial cells (ECs) were used for intracellular Ca

, macrophage adhesion, and protein expression analysis. The whole aorta and aortic root were isolated for histological analysis.

Cell culture studies suggest the partial substitution of SERCA2 C674 increased intracellular Ca

levels and induced ER stress in both BMDMs and ECs. The release of proinflammatory factors and macrophage adhesion increased in SKI BMDMs. In ECs, overexpression of S674 induced endothelial inflammation and promoted macrophage recruitment. SKI mice developed more severe atherosclerotic plaque and macrophage accumulation. Additionally, 4-phenyl butyric acid, an ER stress inhibitor, suppressed ER stress and inflammatory responses in BMDMs and ECs, and alleviated atherosclerosis in SKI mice.

The substitution of SERCA2 C674 thiol accelerates the development of atherosclerosis by inducing ER stress and inflammation. Our findings highlight the importance of SERCA2 C674 redox state in the context of atherosclerosis and open up a novel therapeutic strategy to combat atherosclerosis.

Patients with 11q disorders, including Jacobsen syndrome, often present with a susceptibility for bacterial and prolonged viral and fungal infections partially explained by hypogammaglobulinemia. Additional T lymphocyte or granular neutrophil dysfunction may also be present. In order to evaluate infectious burden and immunological function in patients with 11q disorders, we studied a cohort of 14 patients with 11q deletions and duplications. Clinically, 12 patients exhibited prolonged and repetitive respiratory tract infections, frequently requiring (prophylactic) antibiotic treatment (n = 7), ear-tube placement (n = 9), or use of inhalers (n = 5). Complicated varicella infections (n = 5), chronic eczema (n = 6), warts (n = 2), and chronic fungal infections (n = 4) were reported. Six patients were on immunoglobulin replacement therapy. We observed a high prevalence of low B lymphocyte counts (n = 8), decreased T lymphocyte counts (n = 5) and abnormal T lymphocyte function (n = 12).
