Given the broad interest in using progenitor cells to heal connective tissues, next we compared proliferation and trilineage differentiation of ovine chondrocytes, meniscus cells, and tenocytes. Meniscus cells and tenocytes experienced more than 13 population doublings in 10 days. In chondrogenic culture, cartilage matrix accumulation, and gene expression were largely similar among the cell types. All cell types resisted osteogenesis, while expanded tenocytes and meniscal cells were capable of adipogenesis. While ovine connective tissue cells demonstrated limited lineage plasticity, these data support the potential to promote certain progenitor properties with expansion. © 2020 Orthopaedic Research Society.

However, the property involved in the pathogenicity of these strains has remained unclear. We examined the character of 25 non-O1/non-O139 nontoxigenic V. cholerae isolated during 8 years from 2007 to 2014 in Kolkata. Determination of serogroup showed that the serogroups O6, O10, O35, O36, O39, and O70 were represented by two strains in each serogroup, and the remaining isolates belonged to different serogroups. To clear the character of antibiotic resistance of these isolates, the antibiotic resistance test and the gene analysis were performed. According to antimicrobial drug susceptibility testing, 13 strains were classified as drug resistant. Among them, 10 strains were quinolone resistant and 6 of 13 strains were resistance against more than 3 antibiotics. To define the genetic background of the antibiotic character of these strains, we determined whole-genome sequences of these strains. From the analysis of these sequences, it becomes clear that all of quinolone resistance isolates have mutations in quinolone resistance-determining regions. Further search on the genome sequence showed that 4 strains possess class 1 integrons in their genomes, and that three of four integrons are found to be located in their genomic islands. These genomic islands are novel type. This indicates that various integrons containing drug resistance genes are spreading among V. cholerae non-O1/non-O139 strains through the action of newly-generated genomic islands.

We examined parental depression among African American mothers and nonresident fathers on parenting stress and school involvement in their adolescent sons' school connectedness and violent behaviors. Using a longitudinal study design, parent factors were assessed when sons were 9 years old on youth outcomes at age 15. We found that maternal depression was associated with maternal stress, and maternal stress was indirectly associated with sons' violent behaviors through school connectedness. School involvement among nonresident fathers was positively associated with sons' school connectedness, which was linked to less youth violent behaviors. Maternal stress and nonresident fathers' school involvement are influential for understanding youth violence. Future interventions should incorporate a more nuanced approach when including family factors. © 2020 Wiley Periodicals, Inc.We demonstrate a mechanochemical route for room-temperature and solvent-free derivatization of different types of amides into carbamoyl-isatins (up to 96% conversion or yield), -benzamides (up to 81% yield) and -imides (up to 92% yield). In solution, this copper-catalyzed coupling either does not take place, or requires high temperatures at which it may also be competing with alternative thermal reactivity, highlighting the beneficial role of mechanochemistry for this reaction. Such behavior resembles the previously investigated coupling with sulfonamide substrates, suggesting this type of C-N coupling is an example of a mechanochemically-favored reaction, for which mechanochemistry appears to be a favored environment over solution. link2 © 2020 WILEY-VCH Verlag GmbH & Co.

However, sensitivities of US to detect early-stage HCC in cirrhotic patients are suboptimal. We aimed to compare overall survival and detection rates of very-early-stage HCC in 2 groups group A, undergoing 6-monthly US versus group B, undergoing 6-monthly US alternating with dynamic computed tomography (CT). METHODS This retrospective multi-center study assessed 1,235 cirrhotic patients with CHB under entecavir/tenofovir therapy from 2007 to 2016. The primary endpoint was overall survival rates between the two groups. The Cox proportional hazards model and propensity-score matching analyses were used to assess the effect of surveillance modalities on overall survival and detection of BCLC 0 HCC after balancing. RESULTS During a median follow-up of 4.5 years, 10-year cumulative HCC incidence rates of 16.3% were significantly higher in group B (n=576) than 13.7% in group A (n=659; P less then 0.001). However, in patients with HCC, 10-year overall survival rates of 85.1% were significantly higher in group B than 65.6% in group A (P=0.001 by log-rank test). CT exam alternating with US was independently associated with reduced overall mortality (HR 0.47, P=0.02). Cumulative incidence of Barcelona Clinic Liver Cancer stage (BCLC) 0 HCC were significantly higher in group B than in group A (HR 2.82, P less then 0.001). CONCLUSION In cirrhotic patients with CHB, dynamic CT exam alternating with US led to higher detection rates of very-early-stage HCC and benefit of overall survival compared to US exams.

Periodontal disease occurs with the early loss of deciduous teeth at the age of 2 to 4 years, followed by the loss of permanent teeth during adolescence. Prosthodontics management of PLS patients is very complex and sometimes requires invasive therapeutic treatments. Early diagnosis is essential for correct treatment management avoiding the possibility that patients are early edentulous. Management could be a conventional periodontal treatment and pharmacological therapy but in severe cases, digital techniques, could be help the clinician for increased patient comfort and minimized tissue damage. © 2020 Wiley Periodicals LLC.BACKGROUND Neuroblastoma is one of the most common malignant tumors in childhood. Polymorphisms in proto-oncogene MYC are implicated in many cancers, although their role in neuroblastoma remains unclear. In the present study, we attempted to investigate the association between MYC gene polymorphisms and neuroblastoma susceptibility in Chinese children. METHODS We included two MYC polymorphisms (rs4645943 and rs2070583) and assessed their effects on neuroblastoma risk in 505 cases and 1070 controls via the Taqman method. link3 RESULTS In single and combined locus analysis, no significant association was found between the two selected polymorphisms and neuroblastoma susceptibility. In stratification analysis, the rs4645943 CT/TT genotypes were significantly associated with a decreased neuroblastoma risk in subjects with tumors originating from other sites [adjusted odds ratio (OR) = 0.42, 95% confidence interval (CI) = 0.21-0.84, p = 0.013]. Meanwhile, the presence of one or two protective genotypes was significantly associated with a decreased neuroblastoma risk in subjects with tumors arising from other sites (adjusted OR = 0.50, 95% CI = 0.26-0.96, p = 0.036). CONCLUSIONS The present study indicates that MYC gene polymorphisms may have a weak effect on the neuroblastoma risk, which neeeds to be verified further. © 2020 John Wiley & Sons, Ltd.BACKGROUND X-linked intellectual disability type Nascimento, also known as UBE2A deficiency syndrome, is an intellectual disability syndrome characterized by moderate to severe intellectual disability, dysmorphic facial features, speech impairment, genital anomalies and skin abnormalities. The syndrome is caused by mutations of the UBE2A gene, or larger deletions of Xq24 encompassing UBE2A. METHODS We report the case of a 19 years old male with UBE2A deficiency syndrome, who showed severe intellectual disability and seizures. Whole exome sequencing and Sanger sequencing were used to identify the disease-causing mutations in this intellectual disabilities and epilepsy patient. RESULTS A novel UBE2A mutation (c.TAT245TGT, p.Tyr82Cys) was identified in our patient. The heterozygous missense UBE2A mutation was identified in his mother, but not in his father or sister. CONCLUSION This study identified a novel UBE2A mutation in a patient with severe intellectual disability and seizures. Our findings expand the mutational spectrum of UBE2A gene.

The average age of the children was (6.3 ± 0.3) months, 22 of them were boys (18.0%) and 100 were girls (82.0%). An erythometry and ultrasound examination were performed to determine the depth of the neoplasm, to assess its blood flow, and the presence and diameter of the supply vessels. Studies of these indicators were conducted for patients before and after the treatment. Laser treatment was performed on 109 patients with 119 hemangiomas. A total of 81 superficial hemangiomas underwent a short course of laser therapy (2-5 procedures) and remaining patients with 38 combined hemangiomas received a long course of laser treatment, consisting of 6 to 10 procedures. Restoration of normal color, skin relief, and the absence of scars were noted in post-treatment sample on evaluation.
