The flora of Laos is composed of 5,005 species in 1,373 genera and 188 families of seed plants. Floristic and geographical attributes of the flora were analyzed. Tropical floristic elements at the family and generic levels contributed a majority (62.23% of the families and 82.30% of the genera) of the flora, of which the dominant geographical elements were pantropical distribution (42.02% of families) and tropical Asian distribution (30.08% of genera). This revealed that the flora of Lao PDR is tropical in nature and has a conspicuously tropical Asian affinity...

LSD1 (Lysine Specific Demethylase1)/KDM1A (Lysine Demethylase 1A), a flavin adenine dinucleotide (FAD)-dependent histone H3K4/K9 demethylase, sustains oncogenic potential of leukemia stem cells in primary human leukemia cells. However, the pro-differentiation and anti-proliferation effects of LSD1 inhibition in acute myeloid leukemia (AML) are not yet fully understood. Here, we report that small hairpin RNA (shRNA) mediated LSD1 inhibition causes a remarkable transcriptional activation of myeloid lineage marker genes (CD11b/ITGAM and CD86), reduction of cell proliferation and decrease of clonogenic ability of human AML cells...

The Ts65Dn is a popular mouse model of Down syndrome (DS). It displays DS-relevant features of learning/memory deficits and age-related loss of functional markers in basal forebrain cholinergic neurons. Here we describe protein expression abnormalities in brain regions of 12-month-old male Ts65Dn mice. We show that the magnitudes of abnormalities of human chromosome 21 and non-human chromosome 21 orthologous proteins are greater at 12 months than at ∼6 months. Age-related exacerbations involve the number of components affected in the mechanistic target of rapamycin pathway, the levels of components of the mitogen-activated protein kinase pathway, and proteins associated with Alzheimer's disease...

Neuroligins and neurexins promote synapse development and validation by forming trans-synaptic bridges spanning the synaptic cleft. Select pairs promote excitatory and inhibitory synapses, with neuroligin 2 (NLGN2) limited to inhibitory synapses and neuroligin 1 (NLGN1) dominating at excitatory synapses. The cell-surface molecules, MAM domain-containing glycosylphosphatidylinositol anchor 1 (MDGA1) and 2 (MDGA2), regulate trans-synaptic adhesion between neurexins and neuroligins, impacting NLGN2 and NLGN1, respectively...

Orthobunyaviruses are enveloped viruses that can cause human and animal diseases. A novel and major member is the Schmallenberg virus (SBV), the etiological agent of an emerging disease of ruminants that has been spreading all over Europe since 2011. The glycoproteins Gn and Gc of orthobunyaviruses mediate the viral entry, and specifically Gc is a major target for the humoral immune response. For example, the N terminal subdomain of the SBV glycoprotein Gc is targeted by neutralizing monoclonal antibodies that recognize conformational epitopes...

Maturation is a characteristic of sugarcane plant (Saccharum spp.) and even when grown under the same soil and climate conditions the varieties differ on the maturation curve. Thus, studies that allow establishing maturation curves of different sugarcane genotypes in the local soil and climate may indicate the proper harvesting period to ensure better quality of the raw material. This study aimed to analyze the levels of soluble sugars during the maturation phase and assess the technological and productivity indexes of four irrigated sugarcane genotypes in the region of Rio Largo, Alagoas...

Metastasis is the sole cause of cancer death and there is no curable means in clinic. Cellular protein CRMP4 (DPYSL3 gene) was previously defined as a metastasis suppressor in human prostate cancers since its expression is dramatically reduced in lymphatic metastatic diseases and DPYSL3 overexpression in prostate cancer cells significantly suppressed cancer cell migration and invasion. To develop a CRMP4-based antimetastasis therapeutic approach, the small activating RNA (saRNA) technique was utilized to enhance CRMP4 expression in prostate cancer cells...

Robotic upper urinary tract reconstruction (UUTR) has been widely utilized for surgical management of congenital obstruction. To further reduce morbidity and simplify postoperative care, outpatient robotic pyeloplasty (RP) and robotic ureteroureterostomy (RUU) were performed without ureteral stents, drains, or urethral catheters. The aim of the study was to assess the safety of performing tubeless robotic UUTR as an outpatient procedure. A retrospective review was performed for patients who underwent outpatient tubeless RP and RUU between July 2015 and January 2017...

Concerns over heat illness have been an increasing social problem in humid subtropical regions. One measure for avoiding excessive heat stress in hot outdoor environments is the use of parasols or umbrellas. The advantage of parasols is that they are a mobile and inexpensive way to provide personal shade outdoors. The objectives of this study were to compare the wet-bulb globe temperature (WBGT) under parasols and at an unshaded point as a reference, and to quantify the reduction in WBGT from the use of parasols in a humid subtropical region...

Natural killer (NK) cells are innate immune effector cells that play a crucial role in immune surveillance and the destruction of cancer cells. NK cells express a low-affinity receptor for the Fc or constant region of immunoglobulin G (FcγRIIIa) and multiple cytokine receptors that respond to antibody-coated targets and cytokines in the tumor microenvironment. In the present work, microarray gene expression analysis revealed that the IL-21 receptor (IL-21R) was strongly upregulated following FcR stimulation...

In some medical-imaging procedures using CBCT and fluoroscopy, it may be needed to visualize only the center of the field-of-view with optimal quality. To reduce the dose to the patient as well as enable increased contrast in the region of interest (ROI) during CBCT and fluoroscopy procedures, a 0.7 mm thick Cu ROI attenuator with a circular aperture 12% of the FOV was used. The aim of this study was to quantify the dose-reduction benefit of ROI imaging during a typical CBCT and interventional fluoroscopy procedures in the head and torso...

Chunyu Chen, Juan P Steibel, Robert J Tempelman
A currently popular strategy (EMMAX) for genome wide association (GWA) analysis infers association for the specific marker of interest by treating its effect as fixed while treating all other marker effects as classical Gaussian random effects. It may be more statistically coherent to specify all markers as sharing the same prior distribution, whether that distribution is Gaussian, heavy-tailed (BayesA), or has variable selection specifications based on a mixture of, say, two Gaussian distributions (SSVS). Furthermore, all such GWA inference should be formally based on posterior probabilities or test statistics as we present here, rather than merely being based on point estimates...

BACKGROUND: Pain intensity ratings and opioid consumption (OC) are ubiquitous indicators of pain in postoperative trials of the efficacy of interventional procedures. Unfortunately, consensus on the appropriate statistical handling of these outcomes has not been reached. The aim of this article was, therefore, to reexamine original data obtained from a postoperative analgesic drug trial, applying a collection of standard statistical methods in analgesic outcome assessments. Furthermore, a modified integrated assessment method of these outcomes was evaluated...

Carbonic anhydrase IX has emerged as a promising target for cancer therapy. It is highly up-regulated in hypoxic regions and mediates pH regulation critical for tumor cell survival as well as extracellular acidification of the tumor microenvironment which promotes tumor aggressiveness via various mechanisms, such as augmenting metastatic potential. Therefore, the aim of this study was to analyze the complex interdependency between CA IX and the tumor microenvironment in prostate tumor cells in concern of potential therapeutic implications...

The 27.8 kDa protein in flounder gill (FG) cells was previously proved to be a receptor specific for lymphocystis disease virus (LCDV) entry and infection. In this paper, a 32 kDa viral attachment protein (VAP) of LCDV specifically binding to the 27.8 kDa receptor (27.8R) was found by far-Western blotting coupled with monoclonal antibodies (MAbs) against 27.8R. The 32 kDa protein was confirmed to be encoded by the open reading frame (ORF) 038 gene in LCDV-C, and predicted to contain a putative transmembrane region, multiple N-myristoylation and glycosylation sites and phosphorylation motifs...
