Precursor protein translocation across the outer chloroplast membrane depends on the action of the Toc complex, containing GTPases as recognizing receptor components. The G domains of the GTPases are known to dimerize. In the dimeric conformation an arginine contacts the phosphate moieties of bound nucleotide in trans. Kinetic studies suggested that the arginine in itself does not act as an arg...

Endocrine disruptors in water are contaminants of emerging concern due to the potential risks they pose to the environment and to the aquatic ecosystems. In this study, a solar photocatalytic treatment process in a pilot-scale compound parabolic collector (CPC) was used to remove commercial estradiol formulations (17-β estradiol and nomegestrol acetate) from water. Photolysis alone degraded up ...

Robots can provide assistance with activities of daily living (ADLs) to humans with motor impairments. Specialized robots, such as desktop robotic feeding systems, have been successful for specific assistive tasks when placed in fixed and designated positions with respect to the user. General-purpose mobile manipulators could act as a more versatile form of assistive technology, able to perform...

Background: Some patients with Intractable Vasospastic Angina (i-VSA) have angina attacks, irrespective of vasodilator treatment. Despite the significance of the prediction of i-VSA in the clinical setting, the means to accomplish it remain unclear. Therefore, we investigated the relationship between i-VSA clinical parameters, including angiographic findings from the Spasm Provocation Test (SPT...

iRHOM2 is a highly conserved, catalytically inactive member of the Rhomboid family, which has recently been shown to regulate the maturation of the multi-substrate ectodomain sheddase enzyme ADAM17 (TACE) in macrophages. Dominant iRHOM2 mutations are the cause of the inherited cutaneous and oesophageal cancer-susceptibility syndrome tylosis with oesophageal cancer (TOC), suggesting a role for t...

Studies have demonstrated that total osteocalcin (TOC) is associated with metabolic syndrome (MetS) and therefore might influence the risk of cardiovascular disease in humans. Undercarboxylated osteocalcin (uOC) regulates insulin secretion and sensitivity in mice, but its relation to MetS in humans is unclear. We aimed to determine whether uOC is related to MetS and/or its individual components...

Correlation of glycated hemoglobin (HbA(1c)) level with degrees of certain peroxidative changes in erythrocyte membrane lipids in diabetic patients have been reported. In the present study, peroxidation of erythrocyte lipids was assessed by changes in tocopherols (Toc), phospholipids (PL), and malondialdehyde (MDA). Membrane cholesterol, Toc, and PL were determined from the same lipid extract. ...

A particle-into-liquid sampler (PILS) was coupled with a total organic carbon analyzer (TOC) and two ion chromatographs (IC) to enable high time-resolution measurements of water-soluble ions and water-soluble organic carbon (WSOC) by a single sampling and analytical setup. The new high time-resolution measurement system, the PILS-TOC-IC, was able to provide essential chemical and physical infor...

CONTEXT In mice, undercarboxylated osteocalcin (ucOC) modulates insulin secretion and sensitivity and increases testosterone (T) secretion from Leydig cells, but human data are lacking. We hypothesized that ucOC is associated with diabetes risk and modulates sex hormone concentrations in older men, distinct from other bone turnover markers. PARTICIPANTS PARTICIPANTS were community-dwelling me...
