The plasma corticosterone level of all groups was also evaluated.

Results showed increased plasma corticosterone levels, stress-induced deficits in the NORM and IA tests, and increased anxiety-like behaviors. EE and RJ improved these deficits with a decline in serum corticosterone and also increased BDNF levels in the hippocampus and PFC in stressed ones.

The EE and the RJ prevented the detrimental effects of stress on anxiety-like behaviors and memory processes. These treatments can protect susceptible brain areas against chronic stress via improvement in behavioral and cognitive impairments through mediating BDNF expression.

Thereby, mitochondrial dysfunction represents one common underlying mechanism, which is being investigated in mouse models. However, the influence of the selected diets in preclinical studies on cognition and mitochondrial function has not yet been reported cohesively.Methods Therefore, we present the results of three different studies that addressed this question. First, we investigated the influence of two standard control chow diets and a special diet low in antioxidants over 6 months in aged NMRI mice. Additionally, a 70% high-fat (HF) chow diet as well as a western-style diet (WSD) rich in lard and fructose were examined in C57/BL6 mice. Cognitive performance, mitochondrial function and bioenergetics in the brain were investigated. Moreover, cerebral expression of genes involved in biogenesis and antioxidant defence (citrate synthase, complex I, complex IV, SOD2, Cat1, GPx-1) were quantified.Results The results show that a modified, low antioxidant diet increased ATP levels in the brain of aged mice, while cognitive functions remained largely unaffected. A HF diet also showed significant effects on ATP levels and gene expression levels of relevant antioxidant markers, while the WSD had marginal effects on mitochondrial function and bioenergetics in the brain.Discussion Our results indicate that standard- and special diets have an impact on cognition and mitochondrial function in the brain. Thus, appropriate caution is warranted when selecting a suitable diet for preclinical studies in mice.Amphetamine users have deficits in cognitive performance; however, the effects of duration and amount of use on cognitive decline remain elusive. The aim of this study was to evaluate the correlates of cognitive functioning in amphetamine users in Saudi Arabia. This was a case-control community-based study, using an Arabic adaptation of Addenbrooke's Cognitive Examination (ACE). The study compared users of amphetamine (n = 50) and controls (n = 50) in terms of performance on the ACE. Amphetamine users underperformed controls in the cognitive domains of attention, memory, language, fluency, and visuospatial faculties, even after controlling for psychiatric and sociodemographic variables. BAY 11-7082 Heavy and prolonged use of amphetamine was associated with worse cognitive performance. Use of amphetamine at lower doses was not associated with worsening of cognitive functioning. link2 The study adds to the evidence that amphetamine use is associated with impairment in cognitive functioning in Saudi Arabia. This has implications in terms of designing therapeutic interventions that account for potential cognitive difficulties in amphetamine abusers.Aging women frequently use hair dye to disguise their age in order to avoid being stigmatized as "old". Recently, however, some have chosen naturally gray hair. Informed by Goffman's theory of stigma, we investigated why they would do so in the face of age-discrimination, and their experiences of the process. We identified two major, oppositional themes, competence and authenticity. Despite wanting to avoid perceptions of old-thus-incompetent, women risked gray hair in order to feel authentic. However, they employed other beauty practices to mitigate the effects of gray hair, indicating conflict between a (subjectively) authentic appearance and societal perceptions of competence.Ovarian cancer is the seventh most common cancer among women worldwide. We assessed the effect of socioeconomic status on ovarian cancer incidence in Canada between 1992 and 2010. We linked data from the Canadian Cancer Registry (CCR), Canadian Census of Population (CCP), and National Household Survey (NHS) to measure socioeconomic inequalities in the incidence of ovarian cancer among Canadian women over the study period. The age-standardized relative and absolute concentration index (RC and AC, respectively) were calculated to quantify income- and education-related inequalities in the incidence of ovarian cancer in Canadian women during this period. Despite a slight increase in the crude incidence of ovarian cancer in Ontario, Quebec, New Brunswick, Newfoundland and Labrador & Prince Edward Island, and Canada as a whole, the incidence of ovarian cancer in Canada has mostly remained stable, between 13 and 15 new cases per 100,000 per year between 1992 and 2010. The estimated age-standardized RC and AC values for the study period did not indicate any statistically significant relationship between income or education status, and the incidence of ovarian cancer in Canada. Future work should be directed at seeking related risk factors other than socioeconomic status that may contribute to the incidence of this disease.

Methylenetetrahydrofolate reductase (MTHFR) C677T polymorphism is the main genetic modulator of homocysteine. Data suggest a potential association of homozygosity for the TT MTHFR genotype with premature myocardial infarction (MI). We explored whether TT homozygosity is associated with long-term prognosis in patients with premature ST-segment elevation MI (STEMI).

A total of 265 consecutive patients who had survived their first STEMI ≤35 years of age were followed for a median of 8 years (5-12). Primary endpoints were cardiac death and secondary endpoints were hospitalizations for acute coronary syndrome, myocardial revascularization, arrhythmic event or ischemic stroke. Serum lipids, homocysteine, folate levels were measured at baseline and all patients were also tested for the MTHFR C677T polymorphism.

During follow-up 14 patients died (cardiac death) [5.3%] while 84 (31.7%) met the secondary endpoints. In univariate Cox regression analysis TT homozygosity predicted the occurrence of cardiac death (Hazard ratio (HR) 4.071; 95% confidence interval (CI) 1.404-11.809,

 = .010) but not the occurrence of secondary endpoints (HR 0.877; 95% CI 0.479-1.605,

 = .669). TT homozygosity remained an independent predictor of cardiac death after adjustment for conventional risk factors (i.e., sex, diabetes mellitus, hypertension, family history of premature coronary artery disease [CAD]) [HR 4.350; 95% CI 1.472-12.856,

 = .008]. The association also remained after adjustment for left ventricular ejection fraction or the presence of significant CAD.

Homozygosity for the TT MTHFR is an independent long-term predictor of cardiac death in patients with premature STEMI.

It is important to understand how healthy lifestyle habits can be developed as they are essential in cardiovascular disease (CVD) prevention. There is limited knowledge regarding whether, and how, engaging occupations (things that people do and occupy themselves with) can promote and help sustain healthy lifestyle habits for persons at risk for CVDs, including stroke.

The aim was to develop knowledge of how engaging in occupations can contribute to changes in lifestyle habits among persons at risk for stroke.

Six adults presenting with stroke risk factors were interviewed on several occasions after participating in an occupation-focused stroke prevention programme. link3 Grounded theory was utilised, and constant comparative methods guided the analysis.

Changing lifestyle habits was perceived as a complex process, much like weaving a fabric with many parallel and interlacing threads. Literacy of both health and occupations and participation in engaging occupations were important facilitators for promoting healthy lifestyle habits, yet engagement in health-promoting occupations was described as conditioned behaviour.

CVD prevention programmes can benefit from incorporating engaging occupations to promote healthy lifestyle habits and literacy of health and occupations. However, contextual factors conditioning health and occupations should be considered when developing and implementing sustainable interventions.

We aimed to compare the safety and effectiveness of low-dose ticagrelor vs standard-dose ticagrelor in Chinese patients with ACS undergoing percutaneous coronary intervention (PCI). In this observational cohort study, a total of 2110 ACS patients who were event-free at 3 months after the index PCI were divided into standard-dose ticagrelor (90 mg twice daily) (n = 1830) or low-dose ticagrelor (45 mg twice daily) (n = 280) on a background of aspirin 100 mg once daily for at least another 9 months. The primary end point was type 2, 3, or 5 bleeding according to the Bleeding Academic Research Consortium (BARC) criteria over a 1-year follow-up period post-PCI. Predictors of the primary end point were identified. Both Cox regression and propensity score matching analyses were used. The cumulative incidence of BARC type 2, 3, or 5 bleeding was lower in the low-dose ticagrelor group vs the standard-dose group either before (adjusted HR 0.24; 95% CI 0.07-0.77; p = .016) or after matching (HR 0.25; 95% CI 0.08-0.85; p = .026). A composite of cardiac death, myocardial infarction, or stroke was not significantly different between the two groups (0.4% vs 0.9%, respectively). By multivariate analysis, only low-dose ticagrelor was a protected predictor of BARC type 2, 3, or 5 bleeding either before (HR 0.28, 95% CI 0.09-0.89) or after matching (HR 0.24, 95% CI 0.07-0.82). A low-dose regimen of ticagrelor might provide better safety than standard-dose ticagrelor in Chinese patients with ACS undergoing PCI.BASP1 is involved in signal transduction and cytoskeleton formation and plays a tumor-promoting or tumor-suppressing role in cancers. We found BASP1 was overexpressed in lung adenocarcinoma tissues and promoted the proliferation and migration of lung adenocarcinoma cells. The mechanism may be related to inhibition of cell apoptosis and abnormal activation of the Wnt/β-catenin pathway and epithelial-mesenchymal transformation. BASP1 is associated with poor prognosis in lung adenocarcinoma.
