Ischemic stroke is one of the leading causes of death and disability in the world. Thrombolytic therapy using recombinant tissue plasminogen activator (rtPA), the only FDA-approved drug for acute ischemia, is limited by a narrow therapeutic time window and risk of hemorrhage. There is a serious need for a neuroprotective therapy which is clinically viable. We earlier demonstrated that peripheral sensory stimulation (PSS) is a potential therapeutic intervention for hyperacute ischemia resulting in recovery of neurovascular functions when administered immediately following ischemia onset in a rat model...

Previous results suggest that haptic guidance enhances learning of the timing components of motor tasks, whereas error amplification is better for learning the spatial components. In this paper we evaluate a novel mixed guidance controller that combines haptic guidance and error amplification to simultaneously promote learning of the timing and spatial components. The controller is realized using a saddle-like force field around the desired movement position. This force field has a stable manifold tangential to the trajectory that guides subjects in velocity related aspects...

The IntraVAD is an intra-aortic left ventricular assist device (LVAD) to be located in the ascending aorta. In order to enhance unloading and promote coronary flow for the left ventricle (LV), an operating mechanism, reverse-rotation control (RRc) mode, has been developed for the IntraVAD and tested in vitro in a mock circulation loop (MCL). The RRc mode consists of forward rotation (FR) and reverse rotation (RR). The synchronization between the IntraVAD and the LV was studied to offload the ventricle more effectively and to improve myocardial perfusion...

In the present study we investigated brain network connectivity differences between patients with relapsing-remitting multiple sclerosis (RRMS) and healthy controls (HC) as derived from functional resonance magnetic imaging (fMRI) using graph theory. Resting state fMRI data of 18 RRMS patients (12 female, mean age ± SD: 42 ± 12.06 years) and 25 HC (8 female, 29.2 ± 5.38 years) were analyzed. In order to obtain information of differences in entire brain network, we focused on both, local and global network connectivity parameters...

A new technique for improving the signal reconstruction performance for compressive sensing of gait signals is proposed. The algorithm is based on the minimization of a pseudo-norm which promotes group-block-sparse structure on the first-order difference of the signal. Signal blocks in foot gait signals occur as groups, and the locations of the group are estimated based on the regularization promoting block-sparse structure. The group locations are used for minimizing the pseudonorm for promoting group-block-sparse structure...

The nitrate (NO3(-) ) transporter has been selected as an important gene maker in the process of environmental adoption in rice cultivars. In this work, we transfered another native OsNAR2.1 promoter with driving OsNAR2.1 gene into rice plants. The transgenic lines with exogenous pOsNAR2.1:OsNAR2.1 constructs showed enhanced OsNAR2.1 expression level, compared with wild type (WT), and (15) N influx in roots increased 21-32% in response to 0.2 mM and 2.5 mM (15) NO3(-) and 1.25 mM (15) NH4(15) NO3 . Under these three N conditions, the biomass of the pOsNAR2...

Physical activity improves health and may delay the onset of several chronic diseases. For women in particular, the rate of these diseases accelerates at middle age; therefore it is important to identify the determinants of health-enhancing physical activity during midlife in this population. In this study, we focused on determinants that are unique to the female sex, such as childbearing and menopause. The main objective was to characterize the level of physical activity and differences between active and inactive middle-aged Finnish women...

School nursing practice establishes itself in the midst of both education and nursing philosophies, ethics, standards, laws, and regulations. Treading these two worlds is difficult at times and requires that a school nurse possess a strong foundational knowledge base, seek professional collaboration, and navigate conflicting professional demands in order to promote student and public safety. This article is Part 2 of a four-part series that recounts the inspiring story of a school nurse, Ellen Johnsen, who did just that back in the 1980s in Broken Arrow, Oklahoma...

A homogeneous Nb-doped rutile TiO2 mesocrystal material was synthesized successfully via a facile hydrothermal route. The incorporation of Nb5+ not only promotes the crystallization for the building subunits of the rutile TiO2 mesocrystal but also improves the electrochemical performance at higher current rates. For instance, a capacity of 96.3 mA h g-1 at a current density as high as 40 C and an excellent long-term cycling stability with a capacity loss of ca. 0.006% per cycle at 5 C can be achieved when an appropriate amount of Nb5+ was doped into rutile TiO2 mesocrystal...

Electrospun fibrous polylactide (PLA) membranes have been widely used for peritendinous anti-adhesion, but their degradation may lead to granuloma formation triggered by macrophages as the result of a foreign body reaction. To understand and solve this problem in peritendinous anti-adhesion, the effects of electrospun fibrous PLA membranes (PLA-M) and the mechanism by which macrophages elicit a foreign body reaction should be elaborated. Thus, the purpose of this study was to evaluate the ability of PLA-M and ibuprofen (IBU)-loaded fibrous PLA membranes (IBU/PLA-M) to prevent adhesion/granuloma formation around the tendon, and to understand the mechanism of macrophage infiltration...

Autophagy is a highly conserved degradation process that is involved in the clearance of proteins and damaged organelles to maintain intracellular homeostasis and cell integrity. Type 2 diabetes is often accompanied by dyslipidemia with elevated levels of free fatty acids (FFAs). Podocytes, as an important component of the filtration barrier, are susceptible to lipid disorders. The loss of podocytes causes proteinuria, which is involved in the pathogenesis of diabetic nephropathy. In the present study, we demonstrated that palmitic acid (PA) promoted autophagy in podocytes...

SEPALLATA genes are members of a subfamily of MADS-box transcription factors, and have essential roles in floral organ development and fruit ripening. In this study, the PrupeSEP1 gene was cloned from peach flesh. Its deduced amino acid sequence was very similar to that of MdMADS8 and MdMADS9 in apple and MADS-RIN-like in strawberry. During storage of melting flesh (MF) peach, the pattern of SEP1 expression was similar to that of ethylene biosynthesis and ethylene signal transduction-related gene expression (EIN2 and ETR2)...

S S Witkin, I M Linhares
: Lactobacilli are the most abundant vaginal bacteria in women. They inhibit binding of other bacteria to epithelial cells and produce lactic acid that kills or inhibits the growth of many other bacteria. Lactic acid blocks histone deacetylases, thereby enhancing gene transcription and DNA repair. Lactic acid induces autophagy in epithelial cells to degrade intracellular microorganisms and promote homeostasis. Lactobacilli are tolerated by vaginal epithelial cells and inhibit induction of pro-inflammatory cytokines...

Endophytic fungi have been reported to have the acquired ability to synthesize host plant specific medicinal natural products. Many fungi with such properties have been characterized and optimized for the conditions which favor maximal production of desired products. However, the inherent plant colonization property of promising endophytic fungi is least studied. Exploiting the transgenome functioning of these fungi have immense applications to add beneficial features to non-host plants. In the present study, endophytic fungus Phomopsis sp...

Treatment of acute myeloid leukemia (AML) largely depends on chemotherapy, but current regimens have been unsatisfactory for long-term remission. Although differentiation induction therapy utilizing 1,25(OH)2 D3 (VD3) has shown great promise for the improvement of AML treatment efficacy, severe side effects caused by its supraphysiological dose limit its clinical application. Here we investigated the combinatorial effect of l-asparaginase (ASNase)-mediated amino acid depletion and the latent alternation of VD3 activity on the induction of myeloid differentiation...

Individual readers vary greatly in the quality of their lexical representations, and consequently in how quickly and efficiently they can access orthographic and lexical knowledge. This variability may be explained, at least in part, by individual differences in exposure to printed language, because practice at reading promotes the development of stronger reading skills. In the present eyetracking experiment, we tested the hypothesis that the efficiency of word recognition during reading improves with increases in print exposure, by determining whether the magnitude of the repetition-priming effect is modulated by individual differences in scores on the author recognition test (ART)...
