Uncommon phenotypes in patients using a pathogenic germline alternative inside DICER1.
Infection with CagA-producing Helicobacter pylori plays a causative role in the development of gastric cancer. Upon delivery into gastric epithelial cells, CagA deregulates prooncogenic phosphatase SHP2 while inhibiting polarity-regulating kinase PAR1b through complex formation. Here, we show that CagA/PAR1b interaction subverts nuclear translocation of BRCA1 by inhibiting PAR1b-mediated BRCA1 phosphorylation. It hereby induces BRCAness that promotes DNA double-strand breaks (DSBs) while disabling error-free homologous recombination-mediated DNA repair. The CagA/PAR1b interaction also stimulates Hippo signaling that circumvents apoptosis of DNA-damaged cells, giving cells time to repair DSBs through error-prone mechanisms. The DSB-activated p53-p21Cip1 axis inhibits proliferation of CagA-delivered cells, but the inhibition can be overcome by p53 inactivation. Indeed, sequential pulses of CagA in TP53-mutant cells drove somatic mutation with BRCAness-associated genetic signatures. Expansion of CagA-delivered cells with BRCAness-mediated genome instability, from which CagA-independent cancer-predisposing cells arise, provides a plausible "hit-and-run mechanism" of H. pylori CagA for gastric carcinogenesis.Babesia spp. are tick-transmitted intra-erythrocytic protozoan parasites that infect humans and animals, causing a flu-like illness and hemolytic anemia. There is currently no human vaccine available. People most at risk of severe disease are the elderly, immunosuppressed, and asplenic individuals. B. microti and B. divergens are the predominant species affecting humans. Here, we present a whole-parasite Babesia vaccine. To establish proof-of-principle, we employed chemically attenuated B. microti parasitized red blood cells from infected mice. To aid clinical translation, we produced liposomes containing killed parasite material. Vaccination significantly reduces peak parasitemia following challenge. B cells and anti-parasite antibodies do not significantly contribute to vaccine efficacy. Protection is abrogated by the removal of CD4+ T cells or macrophages prior to challenge. Importantly, splenectomized mice are protected by vaccination. To further facilitate translation, we prepared a culture-based liposomal vaccine and demonstrate that this performs as a universal vaccine inducing immunity against different human Babesia species.Skp2 and cyclin A are cell-cycle regulators that control the activity of CDK2. Cyclin A acts as an activator and substrate recruitment factor of CDK2, while Skp2 mediates the ubiquitination and subsequent destruction of the CDK inhibitor protein p27. The N terminus of Skp2 can interact directly with cyclin A but is not required for p27 ubiquitination. To gain insight into this poorly understood interaction, we have solved the 3.2 Å X-ray crystal structure of the N terminus of Skp2 bound to cyclin A. The structure reveals a bipartite mode of interaction with two motifs in Skp2 recognizing two discrete surfaces on cyclin A. The uncovered binding mechanism allows for a rationalization of the inhibitory effect of Skp2 on CDK2-cyclin A kinase activity toward the RxL motif containing substrates and raises the possibility that other intermolecular regulators and substrates may use similar non-canonical modes of interaction for cyclin targeting.Interleukin-1 (IL-1) is a key orchestrator of inflammation and plays an important role in tumor progression. Based on preclinical models and human genetic associations, we surmise that targeting IL-1 should be considered in treating selected human tumors as well as in a prevention and/or interception setting.Cervical cancer is ranked as the fourth most common cancer in women worldwide. Monoclonal antibody has created a new dimension in the immunotherapy of many diseases, including cervical cancer. The antibody's ability to target various aspects of cervical cancer (oncoviruses, oncoproteins, and signaling pathways) delivers a promising future for efficient immunotherapy. Besides, technologies such as hybridoma and phage display provide a fundamental platform for monoclonal antibody generation and create the opportunity to generate novel antibody classes including, T cell receptor (TCR)-like antibody. In this review, the current immunotherapy strategies for cervical cancer are presented. We have also proposed a novel concept of T cell receptor (TCR)-like antibody and its potential applications for enhancing cervical cancer therapeutics. Finally, the possible challenges in TCR-like antibody application for cervical cancer therapeutics have been addressed, and strategies to overcome the challenges have been highlighted to maximize the therapeutic benefits.A child who has a parent incarcerated is likely to experience a number of life challenges including school failure, poverty, substance abuse, and justice system involvement. The negative outcomes associated with having a parent incarcerated disproportionately expose children to adverse childhood events (ACE's) which have been associated with higher morbidity and mortality. However, engagement with caring adults who can provide both practical and spiritual mentorship can increase a child's resilience and buffer the impact of these negative outcomes. Church-based mentors have the capacity to provide support to this population when adequately trained in trauma-informed responses. This study describes Camp Agape California (CAC), a church-based mentoring program for children with an incarcerated parent. Specifically, this study describes the development and implementation of a trauma focused mentorship training purposed to equip church members to better meet the needs of this vulnerable population. Seventy-six volunteer mentors from various churches participated in the training and completed the post-training survey. Results suggest that the trauma informed training was effective at increasing knowledge and self-efficacy and was identified as being relevant to the mentor role. Implications for the utility of church-based mentorship for vulnerable populations are explored.Auto-disable (AD) syringes are specifically designed to prevent syringe reuse. However, the notion that specific AD syringe designs may be unsafe due to reuse concerns related to the syringe's activation point has surfaced. We conducted a systematic review for evidence on the association between AD syringe design and syringe reuse, adverse events following immunization (AEFI), or blood borne virus (BBV) transmission. We found no evidence of an association between AD syringe design and unsafe injection practices including syringe reuse, AEFIs, or BBVs. Authors of three records speculated about the possibility of AD syringe reuse through intentionally defeating the disabling mechanism, and one hinted at the possibility of reuse of larger-than-required syringes, but none reported any actual reuse instance. In contrast to AD syringes, standard disposable syringes continue to be reused; therefore, the global health community should expand the use of AD syringes in both immunization and therapeutic context as an essential strategy for curbing BBV transmission.Churches are enduring social institutions that play a critical role in the promotion of health and wellbeing. In this introduction, the function of churches as community change agents is highlighted. A brief history of the role of churches in shaping and transforming social systems is provided along with examples of recent church-based change efforts. Further, this issue presents six articles that explore church-based change efforts impacting relationship development, trauma response, wellbeing, pandemic response, and attitudes toward environmental justice. Each article identifies a specific social problem and examines how churches promote prevention and intervention efforts to address the problem. Overall, this issue suggests that churches continue to serve as a resource for community change and that helping professionals should seek to engage with churches when promoting health.The study aimed to investigate the preservative effects of genistein on articular cartilage in an experimental model of knee osteoarthritis in rats. Thirty male Wistar rats were assigned to three equal groups the sham group (SG), osteoarthritis control group (OAG), and genistein-treated osteoarthritis group (GTG). Intra-articular injections of monosodium iodoacetate were used for osteoarthritis induction. After two weeks of rest for the induction of the inflammatory process, genistein (30 mg/kg/day) vs. saline gavage was administered for eight weeks. Pilaralisib cell line The expression of matrix metalloproteinase (MMP) 8 and 13, Sox5/Sox6, Indian hedgehog (IHH), and Col2 were evaluated in medial femoral condyle sections by immunohistochemical staining. The number of chondrocytes and cartilage thicknesses were also measured and compared among the groups. No significant change in cartilage thickness was observed in GTG compared with OAG (p=0.188). Chondrocyte count was significantly higher in the articular cartilage of GTG compared with OAG (p=0.006). Induction of OA significantly increased the expression of MMP-8, MMP-13, and IHH, but decreased Col2, Sox5, and Sox6 expression (p less then 0.001); these were partially prevented in the GTG. Our findings support the effectiveness of genistein treatment in the prevention of articular cartilage damage in the experimental model of knee osteoarthritis. The proposed mechanism of action is through the suppression of the MMP, IHH, Col2 pathways, besides the induction of Sox5 and Sox6 expression. Novelty -Genistein prevent articular cartilage damage in the experimental model of knee osteoarthritis. -The osteoprotective effect is trough modulation of expression of MMP, Sox, IHH, and Col2 proteins.
Emotional disorders (EDs) are the most prevalent worldwide. Despite psychotherapies are their treatment of choice, there are difficulties to apply them properly in mental health services. Since literature shows that cognitive processes are associated with anxiety and depressive symptoms, more information is needed in order to improve psychological treatments.

To determine the relation between cognitive factors with specific and non-specific ED symptoms in order to promote the development of accurate psychological treatments.

We analyzed the relation between rumination, worry, and metacognition with generalized anxiety, panic, and depression disorder symptoms from a clinical sample of 116 individuals through correlation and linear regression analyses.

Although each specific disorder had a closer link with a particular cognitive process, all general ED symptoms were associated with the three cognitive factors studied.

For "pure" disorders, targeting a concrete cognitive process might be an optimal therapeutic option. However, due to the high comorbidity among EDs, we support the dissemination of the transdiagnostic treatment approach in which all cognitive factors are taken into account.
