Results of the study related to polymorphism of ACE gene (rs1799752)‎, integrin αIIbβ3, and CSK gene (rs1378942) influencing development of arterial hypertension in young patients with metabolic syndrome are presented. Hypertension as a component of the metabolic syndrome was detected in 15.0% of young patients. Prevalence of mutant alleles of the studied genes among the examined patients was quite high, so homozygous DD genotype was found in 21.6%, and mutant D allele of the ACE gene in 47.4%. A high risk of hypertension in patients with MS was detected in carriers of the T allele of the CSK (rs1378942) gene – 54.8%, which was most often observed in a combination of polymorphic ACE and CSK gene loci (p = 0.0053).

Abstract This study investigates whether the perceived opportunity to craft (POC) is related to job crafting (JC) strategies and whether these strategies are related to thriving at work, in terms of both vitality and learning. It aims to verify the mediating role of JC between POC and thriving. Data were collected from 424 accounting professionals in Canada. The structural equation modeling based on bootstrap analysis was used to test mediation. The results indicate that POC is positively related to increasing structural and social resources and challenging job demands and negatively to decreasing hindering job demands. They reveal that increasing structural and social resources enhances learning and mediates the relation between POC and vitality and learning, as do challenging job demands, whereas decreasing hindering job demands does not. This study is one of the first to confirm that POC influences vitality and learning via JC behaviors as mediators.

The present study was designed to gain knowledge about the relationship between job characteristics in the workplace (job demands and job resources), employees’ perceived opportunities to craft, and subsequently their actual job crafting behavior. Specifically, the potential mediating role of perceived opportunities to craft could shed better light on the mechanisms that lead employees to job craft in the context of particular work characteristics. We collected data among a group of Dutch health care professionals working in an organization that offers care for patient with mental disabilities (N=522). Participants of the study reported their job demands; workload, emotional demands and work-home interference, their job resources; role clarity, communication and team cohesion, their perceived opportunities to craft, and their job crafting behavior. We tested the hypothesized antecedents of job crafting perceptions and behavior model with structural equation modelling (SEM) analyses. Results indicated that perceived opportunities to craft mediates the relationship between job resources and employees actual job crafting behavior. The insights provided in this study do not only build on job crafting literature but are also helpful to understand which aspects of the workplace influence employees’ job crafting behavior. Therefore, these insights may be useful for the deliberate cultivation of job crafting behavior within organizations.

In the present study, we investigated the activity of the thiazide-sensitive NCC (Na+–Cl− co-transporter) in experimental metabolic syndrome and the role of insulin in NCC activation. Renal responses to the NCC inhibitor HCTZ (hydrochlorothiazide), as a measure of NCC activity in vivo, were studied in 12-week-old ZO (Zucker obese) rats, a model of the metabolic syndrome, and in ZL (Zucker lean) control animals, together with renal NCC expression and molecular markers of NCC activity, such as localization and phosphorylation. Effects of insulin were studied further in mammalian cell lines with inducible and endogenous expression of this molecule. ZO rats displayed marked hyperinsulinaemia, but no differences in plasma aldosterone, compared with ZL rats. In ZO rats, natriuretic and diuretic responses to NCC inhibition with HCTZ were enhanced compared with ZL rats, and were associated with a decrease in BP (blood pressure). ZO rats displayed enhanced Thr53 NCC phosphorylation and predominant membrane localization of both total and phosphorylated NCC, together with a different profile in expression of SPAK (Ste20-related proline/alanine-rich kinase) isoforms, and lower expression of WNK4. In vitro, insulin induced NCC phosphorylation, which was blocked by a PI3K (phosphoinositide 3-kinase) inhibitor. Insulin-induced reduction in WNK4 expression was also observed, but delayed compared with the time course of NCC phosphorylation. In summary, we report increased NCC activity in hyperinsulinaemic rodents in conjunction with the SPAK expression profile consistent with NCC activation and reduced WNK4, as well as an ability of insulin to induce NCC stimulatory phosphorylation in vitro. Together, these findings indicate that hyperinsulinaemia is an important driving force of NCC activity in the metabolic syndrome with possible consequences for BP regulation.
