Adolescents' psychosocial development is generally influenced by their peers. Those facing hospital-based cancer treatment are particularly challenged as they are isolated from their social network and lack sufficient coping resources.

This study explores the adolescent cancer survivor's perceptions and experiences with healthy classmate socialization support efforts via hospital co-admittance, from diagnosis to reinstatement in school, as an intervention of the RESPECT (REhabilitation including Social and Physical Activity and Education in Children and Teenagers with cancer) Study.

A phenomenological, descriptive study.

Using variation sampling, 14 adolescents (aged 14-19), who completed the RESPECT intervention (April 2016-July 2017), participated in qualitative, in-depth, semi-structured interviews that were thematically analysed.

Four themes emerged (a) Ambassadors as liaison persons; (b) Ambassadors as promoters of normalization and identity continuity; (c) Ambassadors as 'behind the scenes' frith cancer. Future programs to sustain socialization in adolescents with cancer should involve healthy peers for the entirety of the treatment period.

Future interventions should offer opportunities for healthy peers to be educated in what it means to live with cancer. Future programs to sustain socialization in adolescents with cancer should involve healthy peers for the entirety of the treatment period.We provide up-to-date morphological and compositional data on otoliths of the osteoglossomorph Goldeye (Hiodon alosoides). Using computed tomography (CT) X-ray, we documented the location of each of the three pairs of otoliths (lapilli, sagittae, and asterisci) in relation to the swim bladder, which extended forward in close proximity to the sagittae and asterisci. The lappili were the largest otoliths in terms of surface area and volume, but the sagittae were highly modified, appearing spiral in shape when viewed dorsally, with a surface area to volume ratio more than double that of the lapilli. Using scanning electron microscopy, the surface of each otolith was viewable in great detail, and small otoconia (~10.5 μm diameter) were observed on each, but were most numerous on the sagittae. On scanning electron micrographs, the sagittae appeared to be bi-lobed, with asymmetrical lobes each oriented in the same general direction. Selleck Ganetespib Using neutron and X-ray diffraction methods, we found three polymorphs of calcium carbonate crystals (aragonite, vaterite, and calcite), sometimes all within the same otolith. However, in general, lapilli and sagittae were composed predominately of aragonite whereas asterisci were composed chiefly of vaterite. With these results, we provide information on a unique species, whose inclusion in future studies would benefit our understanding of fish hearing, fish evolution, and fisheries ecology.Chondroid syringoma (CS) represents the cutaneous counterpart of mixed tumor (pleomorphic adenoma) of salivary glands. Definitive diagnosis is made on histopathology and is based on the presence of characteristic epithelial and stromal components. We report a case of an atypical CS arising on the extremity of an elderly male patient. Histomorphologic features of necrosis and cellular atypia raised suspicion for malignant degeneration, an exceptionally rare circumstance in this context. To further support the diagnosis of malignancy, array comparative genomic hybridization was performed from both low and higher grade areas of the tumor. Both regions demonstrated multiple copy number gains and losses, with additional loss of q7p (TP53), loss of 19p, and loss of heterozygosity on16q demonstrated in the more atypical foci. To our knowledge, this is the first case description of malignant degeneration of a CS with correlative microarray analysis. The findings in this case may prove useful in confirming the diagnosis in future ambiguous cases.Primary dysmenorrhea (PD) is one of the most common gynecological disorders among young women. Bergamot is rich in natural bioactive ingredients, which could potentially ameliorate PD. We aimed to investigate whether the bergamot products (essential oil, juice, and ethanol extract) could improve PD induced by estradiol benzoate and oxytocin. The rats were supplemented with the three doses of bergamot products and positive drugs by gastric perfusion, respectively. The results demonstrated that bergamot products could alleviate PD with dose-dependence via inhibiting the growth of PGF2α /PGE2 ratio, accumulation of MDA, and release of iNOS, and promoting the activities of T-AOC, SOD, CAT, and GSH in uterine tissues. Furthermore, bergamot products could mitigate the writhing response and histopathological alterations in uterine tissues. In addition, bergamot essential oil had greater benefits than the corresponding dose of juice and ethanol extract. PRACTICAL APPLICATIONS An increasing number of young women suffered PD, severely impacting their life. Seeking a healthy diet therapy can effectively avoid the adverse effects of PD drugs. Bergamot as natural fruit is rich in several bioactive ingredients. This study reported the function of bergamot products for alleviating PD via regulating the levels of prostaglandins and inflammatory mediator, and the capacities of antioxidants. This research provides insights for the development of functional foods with improving effect against PD. It also offers us a theoretical basis for the reasonable application of different forms of bergamot products.Rapid eye movement sleep behavior disorder (RBD) is a common condition found in more than 50% of the patients with Parkinson's disease (PD). Molecular imaging shows that PD with RBD (PD-RBD+) have lower striatal dopamine transporter activity within the caudate and putamen relative to PD without RBD (PD-RBD-). However, the characterization of the extra-striatal dopamine within the mesocortical and mesolimbic pathways remains unknown. We aim to elucidate this with PET imaging in 15 PD-RBD+ and 15 PD-RBD- patients, while having 15 age-matched healthy controls (HC). Each participant underwent a single PET scan with [11 C]FLB-457 to detect the D2 receptor availability within the extra-striatal regions of interest (ROI), including the prefrontal, temporal, and limbic areas. [11 C]FLB-457 retention was expressed as the nondisplaceable binding potential. Our results reveal that relative to HC, PD-RBD+ and PD-RBD- patients have lower levels of D2 receptor availability within the uncus parahippocampus, superior, lateral, and inferior temporal cortex. PD-RBD+ showed steep decline in D2 receptors within the left uncus parahippocampus with increasing disease severity, but this was not observed for PD-RBD- patients. Findings imply that extra-striatal dopaminergic system may play a role in contributing to symptomatic progress in PD patients with RBD. However, validation with more advanced PD patients are needed.Hepatitis C virus (HCV) is a positive-sense, single-stranded RNA virus that causes chronic hepatitis and hepatocellular carcinoma. Cellular microRNAs (miRNAs) directly modulate the viral infectivity and indirectly through targeting virus-related host factors. They play an essential role in the progression of different stages of HCV infection. The roles of miR-196 family in HCV infection and hepatocellular carcinoma progression remain poorly understood. Using ViTa databases, miR-196a as a high-score miRNA targeting the NS5 A region of HCV genome was selected. Using dual luciferase assay and an established cell-cultured HCV (HCVcc) system, the effect of miR-196a on HCV genome was assessed. In silico analysis demonstrated the significant role of miR-196a in the downregulation of HCV replication. Using dual luciferase assay, the liver-specific miR-196a and NS5 A gene binding was confirmed. To assess the experimental role of miR-196a, an HCVcc system was established in the Huh 7.5 cell lines. The HCV-RNA 1b derived from an infected patient was transfected into Huh 7.5 cells containing miR-196a lentiviral vectors (Huh 7.5/miR-196a), mocks (Huh 7.5/mock vector), and naïve Huh 7.5 cells. The rate of reduction of the HCV genome replication was assessed using relative real-time PCR assay. These results represent miR-196a overexpression and its roles in regulating HCV genome replication. However, miR-196a may inhibit HCV replication and accelerate the early stages of apoptosis. Overexpression of miR-196a in Huh 7.5 replicon cell is a potential new strategy to prevent hepatitis C infection. The results of this study suggest that miR-196a directly downregulates HCV replication and may serve as a new antiviral therapy.Thalidomide causes teratogenic effects by inducing protein degradation via cereblon (CRBN)-containing ubiquitin ligase and modification of its substrate specificity. Human P450 cytochromes convert thalidomide into two monohydroxylated metabolites that are considered to contribute to thalidomide effects, through mechanisms that remain unclear. Here, we report that promyelocytic leukaemia zinc finger (PLZF)/ZBTB16 is a CRBN target protein whose degradation is involved in thalidomide- and 5-hydroxythalidomide-induced teratogenicity. Using a human transcription factor protein array produced in a wheat cell-free protein synthesis system, PLZF was identified as a thalidomide-dependent CRBN substrate. PLZF is degraded by the ubiquitin ligase CRL4CRBN in complex with thalidomide, its derivatives or 5-hydroxythalidomide in a manner dependent on the conserved first and third zinc finger domains of PLZF. Surprisingly, thalidomide and 5-hydroxythalidomide confer distinctly different substrate specificities to mouse and chicken CRBN, and both compounds cause teratogenic phenotypes in chicken embryos. Consistently, knockdown of Plzf induces short bone formation in chicken limbs. Most importantly, degradation of PLZF protein, but not of the known thalidomide-dependent CRBN substrate SALL4, was induced by thalidomide or 5-hydroxythalidomide treatment in chicken embryos. Furthermore, PLZF overexpression partially rescued the thalidomide-induced phenotypes. Our findings implicate PLZF as an important thalidomide-induced CRBN neosubstrate involved in thalidomide teratogenicity.RNA carries a diverse array of chemical modifications that play important roles in the regulation of gene expression. N6 -methyladenosine (m6 A), installed onto mRNA by the METTL3/METTL14 methyltransferase complex, is the most prevalent mRNA modification. m6 A methylation regulates gene expression by influencing numerous aspects of mRNA metabolism, including pre-mRNA processing, nuclear export, decay, and translation. The importance of m6 A methylation as a mode of post-transcriptional gene expression regulation is evident in the crucial roles m6 A-mediated gene regulation plays in numerous physiological and pathophysiological processes. Here, we review current knowledge on the mechanisms by which m6 A exerts its functions and discuss recent advances that underscore the multifaceted role of m6 A in the regulation of gene expression. We highlight advances in our understanding of the regulation of m6 A deposition on mRNA and its context-dependent effects on mRNA decay and translation, the role of m6 A methylation of non-coding chromosomal-associated RNA species in regulating transcription, and the activities of the RNA demethylase FTO on diverse substrates.
