Framing Effects of Cognitive Behavioural Therapy for Depression on Perceptions of Believability, Acceptability, and Credibility.

While CBT is an effective treatment for depression, uptake can be low. This is largely due to attitudinal barriers. Accordingly, the goals of the current investigation were to (a) tailor and develop persuasive psychoeducational materials to match dominant cultural beliefs about the causes of depression and (b) examine the effectiveness of tailored CBT descriptions in improving CBT perceptions.

Dispositional Mindfulness and Self-Compassion Buffer the Effects of COVID-19 Stress on Depression and Anxiety Symptoms.

Objectives: The COVID-19 pandemic has been associated with a dramatic rise in symptoms of depression and anxiety. Dispositional mindfulness (DM) and self-compassion (SC) have consistently been associated with psychological disorder symptoms and appear to buffer the effects of stress on depression and anxiety.

Methods: Across two studies ( = 888), we examined direct and indirect (moderation) relationships of DM, SC, COVID-19-related stress, and symptoms of depression and anxiety.

Preliminary findings of four-week, task-based anodal prefrontal cortex transcranial direct current stimulation transferring to other cognitive improvements in schizophrenia.

Most transcranial Direct Current Stimulation (tDCS) trials of schizophrenia administer few sessions and do not assess transfer effects to other cognitive domains. In a randomized, double-blind, sham-controlled, parallel groups trial, we determined the extent to which 4-weeks of 2 mA tDCS at 20 min/day totalling 20 tDCS sessions administered during a spatial working memory test, with anodal right dorsolateral prefrontal cortex (DLPFC) and cathodal left tempo-parietal junction (TPJ) placement, as an adjunct to antipsychotics reduced auditory hallucinations and improved cognition in 12 outpatients with schizophrenia. Anodal tDCS significantly improved language-based working memory after 2 weeks and verbal fluency after 2 and 4 weeks.

Oral administration of orthovanadate and Trigonella foenum graecum seed power restore the activities of mitochondrial enzymes in tissues of alloxan-induced diabetic rats.

The effect of oral administration of sodium orthovanadate (SOV) and Trigonella foenum graecum seed powder (TSP), a medicinal plant used extensively in Asia, on the mitochondrial metabolism in the alloxan diabetic rats has been investigated. Rats were injected with alloxan monohydrate (20 mg/100 g body wt) or vehicle (Na-acetate buffer), the former were treated with either 2 IU insulin i.p.

Effects of vanadate on expression of liver arginase in experimental diabetic rats.

This work was carried out to study the effects of vanadate on the expression of liver-type arginase in experimentally induced diabetes in the rat. The results showed that the activity and mRNA levels of arginase were increased significantly in the diabetic condition. Vanadate treatment reversed the increased activity and restored mRNA levels of arginase almost to the control values.

Cross-regulation of beta-catenin-LEF/TCF and retinoid signaling pathways.

Vitamin A derivatives (retinoids) are potent regulators of embryogenesis, cell proliferation, epithelial cell differentiation and carcinogenesis [1]. In breast cancer cells, the effects of retinoids are associated with changes in the cadherin-beta-catenin adhesion and signaling system [2] [3]. beta-catenin is a component of the Wnt signaling pathway, which regulates several developmental pathways [4].

Modulation of mRNA levels of liver arginase by insulin and vanadate in experimental diabetes.

This work was carried out to study the modulation of arginase expression in experimental diabetes. Here, we have demonstrated that liver arginase activity and mRNA levels increased significantly in diabetic condition. Insulin treatment reverses the increased activity and mRNA levels nearly to the control values.

Expression of inducible nitric oxide synthase and enzymes of arginine metabolism in Fusarium kyushuense-exposed mouse lung.

Expression of inducible nitric oxide (NO) synthase (iNOS) and related enzymes of arginine metabolism in the mouse lung exposed to filamentous fungus Fusarium kyushuense was studied by RNA blot, immunoblot, and histological analyses. When mice were exposed intranasally to the fungi only once, no induction of iNOS mRNA was observed. However, when the animals were infected again 6 days after the first exposure, iNOS mRNA was induced, reached a maximum 12-24 h after the exposure, and decreased to an undetectable level at 48 h.

Regulation of the genes for arginase isoforms and related enzymes in mouse macrophages by lipopolysaccharide.

Arginase exists in two isoforms, the hepatic (arginase I) and extrahepatic types (arginase II). Arginase I is markedly induced in rat peritoneal macrophages and rat tissues in vivo by bacterial lipopolysaccharide (LPS). In contrast, both arginase I and arginase II are induced in LPS-activated mouse peritoneal macrophages.

Effects of vanadate and insulin on the activities of selected enzymes of amino acid metabolism in alloxan diabetic rat kidney.

The effects of insulin and the insulin mimetic agent "vanadate" were studied on the activities of alanine aminotransferase, aspartate aminotransferase, glutamate dehydrogenase and arginase in the cytosolic and the mitochondrial fractions of the kidney in control and alloxan induced diabetic rats. An enhancement in the activities of these enzymes were noted in both the fractions of diabetic kidney. Vanadate treatment (0.
