05). These results demonstrate the practical feasibility of using 50 μM NR1 as an antioxidant in boar extender during liquid storage at 17°C, which is beneficial to both spermatozoa quality and fertility.Objective We aimed to investigate Notch pathway dysregulation in solid adenoid cystic carcinoma (AdCC) and to define the association of Notch activation with cell differentiation and prognosis in AdCCs. Materials and methods Notch1 mutations were detected from 125 AdCCs (62 cribriform-tubular; 63 solid). RNA-seq was performed in 16 AdCCs (6 Notch-mutant; 10 wildtype). Notch activation indicator NICD and myoepithelial marker p63 were detected using immunohistochemistry and double-labelling immunofluorescence. The effect of exogenous NICD overexpression on p63 expression and cell proliferation was investigated using western blotting and live-cell imaging. Results We identified 33 Notch1 activating mutations in 27 AdCCs including 26 solid and 1 cribriform-tubular subtypes. Six tumours harbored more than one Notch1 mutation, and 18 Notch1 mutations were novel. Most (47/63, 74.6%) solid AdCCs showed NICD overexpression, whereas 61 of 62（98.4%) cribriform-tubular tumours were negative. NICD and p63 exhibited mutually exclusive expression, and exogenous NICD overexpression promoted cell proliferation and decreased p63 expression. NICD overexpression and Notch mutations were poor indicators for overall-survival and metastasis, especially bone metastasis. Conclusions Dysregulated Notch signalling plays a critical role in AdCC severity. Notch activation may contribute to loss of myoepithelial differentiation as well as high proliferation and metastasis rates in solid AdCC.Physiotherapists can manage chronic pain patients by using technical interventions such as mobility, strengthening, manual therapy, or flexibility in a specific and functional manner, being a key component of a multidisciplinary team. Dentists are involved in the management of different chronic pain conditions such as temporomandibular disorders and sleep disorders such as obstructive sleep apnea. However, they are frequently unaware of the benefits of collaborating with physical therapists. ALK inhibitor In this review, the collaboration of physical therapists and dentists will be explored when managing orofacial pain, headaches, and sleep disorders. The physical therapist is important in the management of these disorders and also in the screening of risk factors.Aims and objectives To evaluate a bundle of interventions, developed and implemented by nurses, to reduce medication administration error rates and improve nurses' medication administration practice. Background Medication administration errors are a problematic issue worldwide, despite previous attempts to reduce them. Most interventions to date focus on isolated elements of the medication process and fail to actively involve nurses in developing solutions. Design An Action Research (AR) three-phase quantitative study. Methods Phase One aimed to build an overall picture of medication practice. Phase Two aimed to develop and implement targeted interventions. During this phase, the research team recruited six clinical paediatric nurses to be part of the AR Team. Five interventions were developed and implemented by the clinical nurses during this phase. The interventions were evaluated in Phase Three. Data collection included medication incident data, medication policy audits based on hospital medication policy own practice culture and environment.Objective Hyposalivation-related xerostomia is an irreversible, untreatable, and frequent condition after radiotherapy for head and neck cancer. Stem cell therapy is an attractive option of treatment, but demands knowledge of stem cell functioning. Therefore, we aimed to develop a murine parotid gland organoid model to explore radiation response of stem cells in vitro. Materials and methods Single cells derived from murine parotid gland organoids were passaged in Matrigel with defined medium to assess self-renewal and differentiation potential. Single cells were irradiated and plated in a 3D clonogenic stem cell survival assay to assess submandibular and parotid gland radiation response. Results Single cells derived from parotid gland organoids were able to extensively self-renew and differentiate into all major tissue cell types, indicating the presence of potential stem cells. FACS selection for known salivary gland stem cell markers CD24/CD29 did not further enrich for stem cells. The parotid gland organoid-derived stem cells displayed radiation dose-response curves similar to the submandibular gland. Conclusions Murine parotid gland organoids harbor stem cells with long-term expansion and differentiation potential. This model is useful for mechanistic studies of stem cell radiation response and suggests similar radiosensitivity for the parotid and submandibular gland organoids.IFN-γ plays a critical role in the immune response to bacterial infections. It is established that IFN-γ is mainly produced by NK/ILC1 cells and T cells, and most of papers have rejected the biologic reality of alternative sources for more than 20 years. Here, we are proposing to revisit this dogma and discuss the role of macrophage-derived IFN-γ in bacterial infections. Our hypothesis is based on a panel of publications and is recently revived by our results on placenta, a chimeric organ in which the immune response is tailored to protect the fetus from mother's immune response. The culture of purified placental macrophages is associated with a production of IFN-γ that may contribute to fetal protection from bacterial infections before eliciting a Th1-like immune response potentially pathogenic for pregnancy. Hence, macrophage IFN-γ may be a novel actor of early crosstalk between innate and adaptive immunity in the context of host defense against bacterial infections.Molecular variant interpretation lacks disease gene-specific cohorts for determining variant enrichment in disease versus healthy populations. To address the molecular etiology of retinal degeneration, specifically the PRPH2-related retinopathies, we reviewed genotype and phenotype information obtained from 187 eyeGENE® participants from 161 families. Clinical details were provided by referring clinicians participating in the eyeGENE® Network. The cohort was sequenced for variants in PRPH2. Variant complementary DNA clusters and cohort frequency were compared to variants in public databases to help us to determine pathogenicity by current American College of Medical Genetics and Genomics/Association for Molecular Pathology interpretation criteria. The most frequent variant was c.828+3A>T, which affected 28 families (17.4%), and 25 of 79 (31.64%) variants were novel. The majority of missense variants clustered in the D2 intracellular loop of the peripherin-2 protein, constituting a hotspot. Disease enrichment was noted for 23 (29.
