Only OCD showed increased GMV in the dorsal striatum with higher changes being associated with more severe OCD symptomatology. Together the findings demonstrate robustly decreased GMV across the disorders in the left IFG, suggesting a transdiagnostic brain structural marker. The functional characterization as a key hub in the cognitive control network and casual interactions with the striatum suggest that deficits in inhibitory control mechanisms may promote compulsivity and loss of control that characterize both disorders.
Vascular endothelial growth factor (VEGF) is a key molecular driver of angiogenesis and vascular permeability and is expressed by a wide variety of neoplasms. Although blood VEGF concentrations have been quantified in intracranial tumors of dogs, cerebrospinal fluid (CSF) VEGF concentration might be a more sensitive biomarker of disease.

Concentrations of VEGF in CSF are higher in dogs with central nervous system (CNS) neoplasia compared to those with meningoencephalomyelitis and other neurologic disorders.

One hundred and twenty-six client-owned dogs presented to a veterinary teaching hospital.

Case-control study. Cerebrospinal fluid was archived from dogs diagnosed with CNS neoplasia and meningoencephalomyelitis. Control dogs had other neurological disorders or diseases outside of the CNS. A commercially available kit was used to determine VEGF concentrations.

Detectable CSF VEGF concentrations were present in 49/63 (77.8%) neoplastic samples, 22/24 (91.7%) inflammatory samples, and 8/39 (20.5%) control samples. The VEGF concentrations were significantly different between groups (P < .0001), and multiple comparison testing showed that both neoplastic and inflammatory groups had significantly higher concentrations than did controls (P < .05), but did not differ from each other. Gliomas and choroid plexus tumors had significantly higher VEGF concentrations than did the control group (P < .05).

Cerebrospinal fluid VEGF concentrations may serve as a marker of neoplastic and inflammatory CNS disorders relative to other conditions.

Treatment history for FLC had included cytotoxic chemotherapy, lenvatinib, and immunotherapy. A CT scan confirmed extensive stage FLC with numerous liver, lung, and pelvic metastasis. Laboratory results showed bilirubin 0.3 mg/dL, creatinine 0.4 mg/dl, leukocytes of 9.5x109 /L, hemoglobin 11.2 g/dL, platelets 369x109 /L, and ammonia 247 µmol/L (reference range 0-32 µmol/L). Plasma amino acid analysis revealed relatively low citrulline (14 µmol/L), arginine (32 µmol/L), and ornithine (35 µmol/L). Urinary orotic acid excretion was markedly elevated at 149 mmol/mol creat (reference range 0.68-3.52 mmol/mol creat).
To explore the experiences of strategic leads for nurse education as they sought to respond to the COVID-19 pandemic.

We utilised a qualitative interpretative approach to explore education leaders' experiences of leading during the early months of the pandemic.

Nineteen leaders with significant strategic responsibility for nurse education in Australia, Canada, New Zealand, Singapore and the United Kingdom were identified via purposive sampling and agreed to participate. Interviews were held between May and July 2020.

Four overarching themes arose from the analysis (1) Crisis driven adaptability & flexibility; (2) Responsive, complex and changing communication; (3) Making decisions for student and staff safety; (4) Looking to the future; stronger partnerships.

Internationally, while nursing education leaders faced different problems, they shared a common goal amidst the crisis to remain student-centred. They demonstrated they were able to face major challenges, respond to large scale logistical problems and make decisions under significant and ongoing pressure.

In responding to the pandemic, nurse leaders shared knowledge and offered mutual support. This bodes well for future collaboration. The move to online learning accelerated an existing trend and it seems likely that this will continue. Given the pressures they experienced over an extended period, the sector may wish to consider how it prepares and supports existing and future leaders.

Herein, TargetScan was used to predict the potential upstream targets of HDAC2, and the role of miR-455-3p was explored. The dual luciferase reporter assay showed that miR-455-3p binds to the 3' UTR of HDAC2 mRNA. Additionally, miR-455-3p was downregulated in the liver tissues of patients with cirrhosis and mice with liver fibrosis, as well as in primary HSCs isolated from fibrotic mouse livers and TGF-β-treated LX-2 cells. In contrast, it is highly expressed in the reversal stage of hepatic fibrosis and MDI-cultured LX-2 cells. Our functional analyses showed that miR-455-3p overexpression facilitated apoptosis and reduced the expression of pro-fibrotic markers and the proliferation of activated LX-2 cells. On the contrary, miR-455-3p inhibition converted inactivated LX-2 cells into activated, proliferative, fibrogenic cells. Interestingly, restoration of HDAC2 expression partially blocked the function of miR-455-3p. Downregulated miR-455-3p expression can be restored by DNA methyltransferases in activated LX-2 cells. Methylation-specific PCR, bisulfite sequencing PCR, and chromatin immunoprecipitation assays indicated that the methylation level of miR-455-3p promoter CpG islands was elevated in TGF-β-treated LX-2 cells and that miR-455-3p was downregulated in activated LX-2 cells by DNA hypermethylation, which is mediated by DNMT3b and DNMT1. In conclusion, miR-455-3p acts as a liver fibrosis suppressor by targeting HDAC2, and its deficiency further aggravates the reversal phase of fibrosis. Thus, the epigenetics mediated miR-455-3p/HDAC2 axis may serve as a novel potential therapeutic target for clinical treatment of hepatic fibrosis.Keloids are fibrotic lesions that grow unceasingly and invasively and are driven by local mechanical stimuli. Unlike other fibrotic diseases and normal wound healing, keloids exhibit little transformation of dermal fibroblasts into α-SMA+ myofibroblasts. This study showed that asporin is the most strongly expressed gene in keloids and its gene-ontology terms relate strongly to ECM metabolism/organization. Experiments with human dermal cells (HDFs) showed that asporin overexpression/treatment abrogated the HDF ability to adopt a perpendicular orientation when subjected to stretching tension. It also induced calcification of the surrounding 3D collagen matrix. Asporin overexpression/treatment also prevented the HDFs from remodeling the surrounding 3D collagen matrix, leading to a disorganized network of thick, wavy collagen fibers that resembled keloid collagen architecture. This in turn impaired the ability of the HDFs to contract the collagen matrix. Asporin treatment also made the fibroblasts impervious to the fibrous collagen contraction of α-SMA+ myofibroblasts, which normally activates fibroblasts. Thus, by calcifying collagen, asporin prevents fibroblasts from linearly rearranging the surrounding collagen; this reduces both their mechanosensitivity and mechanosignaling to each other through the collagen network. This blocks fibroblast activation and differentiation into the mature myofibroblasts that efficiently remodel the extracellular matrix. Consequently, the fibroblasts remain immature, highly proliferative, and continue laying down abundant extracellular matrix, causing keloid growth and invasion. Notably, dermal injection of asporin-overexpressing HDFs into murine wounds recapitulated keloid collagen histopathological characteristics. Thus, disrupted interfibroblast mechanocommunication may promote keloid progression. Asporin may be a new diagnostic biomarker and therapeutic target for keloids.
The aim of this study was to understand the perceptions of 11 Portuguese nurses' stakeholders regarding pressure ulcers prevention practice and reality in the hospital setting.

Convenience sampling was used to recruit nursing stakeholders for a heterogeneous focus group. A semi-structured interview was conducted with 11 nursing stakeholders involved in pressure ulcers prevention and/or patient safety. MaxQda 2020 qualitative analysis software was used in the content analysis and data processing. Informed consent was obtained, and anonymity was guaranteed.

Four themes were approached in the interview (1) Pressure ulcer risk assessment; (2) Nurses and doctors pressure ulcers monitoring; (3) Pressure ulcer risk profiles; and (4) Effective interventions to improve patient safety. The categorisation of the four themes was created aposteriori based on the 'Awareness/Knowledge/Competence, Opportunity, and Motivation - Behaviour Change Wheel' (adapted COM-B system). Interest, responsibility, autonomy, leadershiions for behavioural change in the hospital context related to pressure ulcers prevention through awareness/knowledge/competence, motivation and opportunity to improve care delivered.
The findings provide directions for behavioural change in the hospital context related to pressure ulcers prevention through awareness/knowledge/competence, motivation and opportunity to improve care delivered.Peripheral arterial disease (PAD) is one of the major complications of diabetes due to an impairment in angiogenesis. Since there is currently no drug with satisfactory efficacy to enhance blood vessel formation, discovering therapies to improve angiogenesis is critical. An imidazolinone metabolite of the metformin-methylglyoxal scavenging reaction, (E)-1,1-dimethyl-2-(5-methyl-4-oxo-4,5-dihydro-1H-imidazol-2-yl) guanidine (IMZ), was recently characterized and identified in the urine of type-2 diabetic patients. Here, we report the pro-angiogenesis effect of IMZ (increased aortic sprouting, cell migration, network formation, and upregulated multiple pro-angiogenic factors) in human umbilical vein endothelial cells. Using genetic and pharmacological approaches, we showed that IMZ augmented angiogenesis by activating the endothelial nitric oxide synthase (eNOS)/hypoxia-inducible factor-1 alpha (HIF-1α) pathway. Furthermore, IMZ significantly promoted capillary density in the in vivo Matrigel plug angiogenesis model. Finally, the role of IMZ in post-ischemic angiogenesis was examined in a chronic hyperglycemia mouse model subjected to hind limb ischemia. We observed improved blood perfusion, increased capillary density, and reduced tissue necrosis in mice receiving IMZ compared to control mice. Our data demonstrate the pro-angiogenic effects of IMZ, its underlying mechanism, and provides a structural basis for the development of potential pro-angiogenic agents for the treatment of PAD.
