Phytochemical investigation of Chorisia chodatii Hassl. leaves led to the isolation of an unusual rearranged megastigmane glycoside; chodatiionoside A (1) and another new megastigmane glycoside; chodatiionoside B (2), together with three known megastigmane glycosides (3-5) and one known flavonoid glycoside (6). Their structures were elucidated by spectroscopic methods including 1D and 2D NMR experiments ((1)H, (13)C, DEPT, COSY, HSQC and HMBC) in combination with HR-ESI-MS, CD and modified Mosher's method. As a result, chodatiionoside A has been elucidated as a first example of an unusual rearranged form of megastigmane...

Adverse drug events (ADEs) are more likely to affect geriatric patients due to physiological changes occurring with aging. Even though this is an internationally recognized problem, similar research data in Finland is still lacking. The aim of this study was to determine the number of geriatric medication-related hospitalizations in the Finnish patient population and to discover the potential means of recognizing patients particularly at risk of ADEs. The study was conducted retrospectively from the 2014 emergency department patient records in Oulu University Hospital...

Sleep disturbance is common in patients with heart failure and their family caregivers. The purpose of this study was to determine whether sleep disturbances of patients and their spousal caregivers predicted their own and their partners' quality of life (QoL) in 78 heart failure patient-spousal caregiver dyads. Sleep disturbance was assessed using a composite score of four common sleep complaints. QoL was assessed by the physical and mental well-being subscales of the Short-Form 12 Health Survey. The multilevel dyadic actor-partner interdependence model analysis was used to determine the association between sleep disturbance and QoL...

Starch provides the major source of caloric intake in many diets. Cleavage of starch into malto-oligosaccharides in the gut is catalyzed by pancreatic alpha-amylase. These oligosaccharides are then further cleaved by gut wall alpha-glucosidases to release glucose, which is absorbed into the bloodstream. Potential surface binding sites for starch on the pancreatic amylase, distinct from the active site of the amylase, have been identified through X-ray crystallographic analyses. The role of these sites in the degradation of both starch granules and soluble starch was probed by the generation of a series of surface variants modified at each site to disrupt binding...

Wind disturbance can create large forest blowdowns, which greatly reduces live biomass and adds uncertainty to the strength of the Amazon carbon sink. Observational studies from within the central Amazon have quantified blowdown size and estimated total mortality but have not determined which trees are most likely to die from a catastrophic wind disturbance. Also, the impact of spatial dependence upon tree mortality from wind disturbance has seldom been quantified, which is important because wind disturbance often kills clusters of trees due to large treefalls killing surrounding neighbors...

The impact of reduced dimensionality on the magnetic properties of the tetragonal L1 0 CoPt alloy is investigated from ab initio considering several kinds of surface defects. By exploring the dependence of the magnetocrystalline anisotropy energy (MAE) on the thickness of CoPt thin films, we demonstrate the crucial role of the chemical nature of the surface. For instance, Pt-terminated thin films exhibit huge MAEs which can be 1000% larger than those of Co-terminated films. Besides the perfect thin films, we scrutinize the effect of defective surfaces such as stacking faults or anti-sites on the surface layers...

Human microtubule affinity-regulating kinase 4 (MARK4) is considered as an encouraging drug target for the design and development of inhibitors to cure several life threatening diseases such as Alzheimer disease, cancer, obesity and type-II diabetes. Recently, we have reported four ligands namely, BX-912, BX-795, PKR-inhibitor and OTSSP167 (hydrochloride) which bind preferentially to the two different constructs of human MARK4 containing kinase domain. To ensure the role of ubiquitin associated (UBA) domain in the ligand binding, we made a newer construct of MARK4 which contain both kinase and UBA domains, named as MARK4-F3...

A moiré pattern is created by superimposing two black-and-white or gray-scale patterns of regular geometry, such as two sets of evenly spaced lines. We observed an analogous effect between two transparent phase masks in a light beam which occurs at a distance. This phase moiré effect and the classic moiré effect are shown to be the two ends of a continuous spectrum. The phase moiré effect allows the detection of sub-resolution intensity or phase patterns with a transparent screen. When applied to x-ray imaging, it enables a polychromatic far-field interferometer (PFI) without absorption gratings...

Gene diversity (GD), also called polymorphism information content, is a commonly used measure of molecular marker polymorphism. Calculation of GD for dominant markers such as AFLP, RAPD, and multilocus SSRs is valuable for researchers. To meet this need, we developed a free online computer program, GDdom, which provides easy, quick, and accurate calculation of dominant marker GD with a commonly used formula. Results are presented in tabular form for quick interpretation.

Non-CE MRA techniques (true steady-state free-precession, SSFP) have been used effectively for the selective visualization of the portal venous system and inferior vena cava. Budd-Chiari Syndrome (BCS) encompasses a number of conditions that cause the obstruction of the hepatic outflow tract from the small hepatic veins to the junction of the inferior vena cava (IVC) and right atrium. The purpose of this study was to diagnose BCS with IVC obstruction using respiratory triggered three-dimensional (3D) true SSFP with T-SLIP and compare to digital subtraction angiography (DSA)...

Developmental signaling molecules are used for cell fate determination, and understanding how their combinatorial effects produce the variety of cell types in multicellular organisms is a key problem in biology. Here, we demonstrate that the combination of leukemia inhibitory factor (LIF), bone morphogenetic protein 4 (BMP4), lysophosphatidic acid (LPA), and ascorbic acid (AA) efficiently converts mouse primed pluripotent stem cells (PSCs) into naive PSCs. Signaling by the lipid LPA through its receptor LPAR1 and downstream effector Rho-associated protein kinase (ROCK) cooperated with LIF signaling to promote this conversion...
