After controlling for time-varying covariates, increases in cumulative prior years of weekly cannabis use, but not recent cannabis use, remained associated with increases in depression symptoms and anxiety/depression problems. Specifically, each additional year of prior weekly cannabis use was associated with a small increase in depression symptoms (b = 0.012, p = .005) and anxiety/depression problems (b = 0.009, p = .001). Associations did not vary systematically across time. There was also no evidence of reverse causation. As boys engaged in weekly cannabis use for more years, they showed increases in internalizing problems, suggesting the importance of preventing chronic weekly cannabis use.This study examined the associations between internalizing and externalizing symptoms during early adolescence and the subsequent development of Major Depressive Disorder. The role that temperament plays in predisposing individuals to these particular pathways was also examined. Temperament at approximately age 12 was used to produce a risk-enriched subsample of 243 (124 female) participants. Data was collected in four waves over 6-7 years roughly corresponding to ages 13, 15, 17 and 19. Participants were excluded from the study, prior to the first wave, based on current or prior depressive, substance-use, or eating disorders. Logistic regression analyses revealed that internalizing symptoms and social-externalizing problems were significant risk pathways to the development of depression.

As such, high levels of effortful control acted as a protective factor for the development of depression across both symptom pathways, suggesting that is may be an important target for prevention strategies.The purpose of this study is to evaluate the expression and the prognostic role of main factors, involved in the hypoxia pathway, in patients with clear-cell renal cell carcinoma (ccRCC). Immunohistochemical expression of Hypoxia inducible factors (HIF) HIF-1a, HIF-2a, prolyl hydroxylases PHD1, PHD2, PHD3, and factor inhibiting HIF (FIH) was assessed on a tissue microarray, containing tumour and corresponding normal kidney tissue from 66 patients underwent surgery for ccRCC. Expression levels were evaluated in relation to T stage, Fuhrman grade, cancer-specific, and overall survival (OS). Cytoplasmatic expression of HIF-2a was positively correlated with expression of HIF-1a (p = 0.011). HIF-1a expression was also positively correlated with PHD3 and FIH (p = 0.020 and p = 0.039). Expression of HIF-1a was associated with lower Fuhrman grade (p = 0.008), while HIF-2a overexpression with unfavourable grade (p = 0.026). PHD3 was significant downregulated (84.8%). Age, LDH, presence of necrosis, Fuhrman grade, T stage, and HIF-2a cytoplasmatic expression were significant associated with OS of patients in univariable analysis. In multivariable analysis, HIF-2a expression (p = 0.006) and T stage (p = 0.001) remained as the only independent predictors for overall survival. These results indicate that HIF-2a overexpression not only is inversely correlated with Fuhrman grade in ccRCC, but also represents a strong independent prognostic factor for a poor overall survival.Müller cells may have stem cell-like capability as they regenerate photoreceptor loss upon injury in some vertebrates, but not in mammals. Indeed, mammalian Müller cells undergo major cellular and molecular changes summarized as reactive gliosis. Transforming growth factor beta (TGFβ) isoforms are multifunctional cytokines that play a central role, both in wound healing and in tissue repair. Here, we studied the role of TGFβ isoforms and their signaling pathways in response to injury induction during tissue regeneration in zebrafish and scar formation in mouse. Our transcriptome analysis showed a different activation of canonical and non-canonical signaling pathways and how they shaped the injury response. In particular, TGFβ3 promotes retinal regeneration via Smad-dependent canonical pathway upon regulation of junb gene family and mycb in zebrafish Müller cells. However, in mice, TGFβ1 and TGFβ2 evoke the p38MAPK signaling pathway. The activation of this non-canonical pathway leads to retinal gliosis. Thus, the regenerative versus reparative effect of the TGFβ pathway observed may rely on the activation of different signaling cascades. This provides one explanation of the different injury response in zebrafish and mouse retina.Maize was one of the first eukaryotic species in which individual chromosomes can be identified cytologically, which made maize one of the oldest models for genetics and cytogenetics research. Nevertheless, consistent identification of all 10 chromosomes from different maize lines as well as from wild Zea species remains a challenge. We developed a new technique for maize chromosome identification based on fluorescence in situ hybridization (FISH). We developed two oligonucleotide-based probes that hybridize to 24 chromosomal regions. Individual maize chromosomes show distinct FISH signal patterns, which allow universal identification of all chromosomes from different Zea species. We developed karyotypes from three Zea mays subspecies and two additional wild Zea species based on individually identified chromosomes. A paracentric inversion was discovered on the long arm of chromosome 4 in Z. nicaraguensis and Z. luxurians based on modifications of the FISH signal patterns. Chromosomes from these two species also showed distinct distribution patterns of terminal knobs compared with other Zea species. These results support that Z. nicaraguensis and Z. luxurians are closely related species.The health care needs and service experiences of higher education students require more research attention, given the increase in students who have a long-term illness, medical condition, or disability ("condition"). It is also important to consider the experiences of rising numbers of international students. This exploratory qualitative study used face-to-face interviews and the common-sense model of self-regulation to investigate students' perceptions and coping behaviours, in a higher education institution in the UK. Thematic analysis was used to analyse the data. Twenty students who self-identified as having a condition were interviewed. This study adds depth to the understanding of the connections between students' health-related experiences and their personal, academic, and post-graduation aspirations and the support needs of students, including international students. To optimise institutional support, innovations in partnerships with local care organisations and within the university, staff training about conditions, peer mentorship, and information outreach especially to international students, should be considered.
