Ion pumping microbial rhodopsins are photochemically active membrane proteins, converting light energy into ion-motive-force for ATP synthesis. Nonlabens dokdonensis rhodopsin 2 (NdR2), was recently identified as a light-driven Na(+) pump. However, few functional studies on NdR2 have been conducted to elucidate its mechanism of ion transport. By reconstituting NdR2 into liposomes, we proved that NdR2 functions as a light-driven Na(+)/H(+) pump. As Na(+) concentration increased, the dominant H(+) pump activity switched to the Na(+) pump activity at neutral pH...

BACKGROUND: People with low back pain exhibit altered postural coordination that has been suggested as a target for treatment, but heterogeneous presentation has rendered it difficult to identify appropriate candidates and protocols for such treatments. This study evaluated the associations of task-related and person-related factors with the effect of low back pain on anticipatory postural adjustments. METHODS: Thirteen subjects with and 13 without low back pain performed seated, rapid arm flexion in self-initiated and cued conditions...

The torque teno virus (TTV) is a recently discovered DNA virus that has been detected in many different hosts, including humans, livestock and poultry. To date, there is no report of pigeon TTV (PTTV) from anywhere in the world. To investigate the distribution of PTTV in pigeons from the eastern Chinese province of Jiangsu and characterize their genomes, we employed PCR to detect PTTV in 144 samples collected from 6 pigeon plants in Jiangsu province, amplify complete genomes from representative samples and analyze genetic characteristics using bioinformatics...

Patients with chronic myeloid leukemia (CML) have a t (9;22)(q34;q11.2) or variant translocation that results in a BCR-ABL1 fusion gene. For many years, conventional karyotyping has been used as the standard diagnostic tool for t (9;22) (q34;q11.2). However, it has several limitations that may lead to failure for detecting BCR-ABL1 gene rearrangements in around 5% of all CML patients. Although reverse transcription polymerase chain reaction (RT-PCR) has evolved as a sensitive method for detecting BCR-ABL1 translocation, this method fail to detect certain BCR-ABL1 fusion transcript type, such as e13a3 (also known as b2a3), as a result of many commercially available and laboratory-developed primer sets...

Combretastatin A-4 phosphate (CA4P) selectively blocks tumor blood flow. However, the detailed mechanisms through which CA4P specifically affects tumor blood vessels are not well understood. Recent reports revealed that tumor tissue-derived endothelial cells (TECs) have various specific features in comparison with normal tissue-derived endothelial cells (NECs). Thus, abnormalities in TECs may be involved in the selective vascular blockade mechanism of CA4P. In this study, we evaluated the effects of CA4P on canine NECs and TECs using confocal microscopy...

Melamine is commonly used in the chemical industry, and it has been found to exist on food processing equipment and utensils. Previous investigations suggested that melamine alone or its combination with cyanuric acid appears to be toxic to immune system in animals. The objective of this study is to investigate the potential effects of melamine with or without cyanuric acid on immune function in ovalbumin- sensitized mice. Our data indicated that melamine-related administration caused a significant decreasing in the content of IL-4 in mice in comparison to negative control group...

It has been proposed that Emu oil possesses skin permeation-enhancing effect. This study aimed to address its possible penetration enhancement mechanism(s) using IR microscopy, in accordance with LPP theory. The penetration of Emu oil through the layers of human skin was accomplished by monitoring oil-IR characteristic feature at 3006cm(-1). The unsaturated components of Emu oil accumulated at about 270μm depth of skin surface. The interaction of Emu oil with lipid and protein constituents of SC was investigated in comparison with a commonly used enhancer, IPM...

Recent studies showed that sulfidated nanoscale zerovalent iron (S-nZVI) is a better reducing agent than nanoscale zerovalen iron (nZVI) alone for reductive dechlorination of several organic solvents such as trichloroethylene (TCE) due to the catalytic role of iron sulfide (FeS). We measured the rates of transformation of hexabromocyclododecane (HBCD) by S-nZVI and compared them to those by FeS, nZVI, and reduced sulfur species. The results showed that: i) HBCD (20 mg L(-1)) was almost completely transformed by S-nZVI (0...

Bacteriophages and archaeal viruses contribute, through lysogenic conversion or transduction, to the horizontal transfer of genetic material between microbial genomes. Recent genomics, metagenomics, and single cell studies have shown that lysogenic conversion is widespread and provides hosts with adaptive traits often associated with biotic interactions. The quantification of the evolutionary impact of transduction has lagged behind and requires further theoretical and experimental work. Nevertheless, recent studies suggested that generalized transduction plays a role in the transfer of antibiotic resistance genes and in the acquisition of novel genes during intra-specific bacterial competition...

Numerous environmental pollutants have been identified as potential obesogenic compounds affecting endocrine signaling and lipid homeostasis. Among them, well-known organotins such as tributyltin (TBT) and triphenyltin (TPT), can be found in significant concentrations in aquatic environments. The aim of the present study was to investigate in vitro the effects of TBT and TPT on the development and lipid metabolism of rainbow trout (Onchorynchus mykiss) primary cultured adipocytes. Results showed that TBT and TPT induced lipid accumulation and slightly enhanced peroxisome proliferator-activated receptor gamma (PPARγ) and CCAAT enhancer binding protein alpha (C/EBPα) protein expression when compared to a control, both in the presence or absence of lipid mixture...

Leadership is often viewed as being critical to successful natural resource management. This research focuses on a set of leaders identified through a social network analysis of fishers in a rural coastal region. Leaders' connections to different fisheries are evaluated, and these actors are found to be significantly more diversified than other fishers in the area. Drawing on theory related to institutional entrepreneurship and a series of in-depth interviews with these actors, this paper puts forward several hypotheses to explain how diverse social-ecological connections facilitate leadership...

RATIONALE: Despite the publicised health risks associated with its usage, sunbed tanning remains popular in many Western countries. Previous research indicates that knowledge of the harmful effects does not necessarily lead to a reduction in sunbed use. OBJECTIVE: The aim of this study was to develop a more extensive social psychological understanding of sunbed use, in the United Kingdom, by exploring the social representations of sunbed tanning held by both those who use and who have never used sunbeds...

There are currently 1.5 million undocumented Asians and Pacific Islanders (APIs) in the US. Undocumented API young adults, in particular, come of age in a challenging political and social climate, but little is known about their health outcomes. To our knowledge, this is the first study to assess the psychosocial needs and health status of API undocumented young adults. Guided by social capital theory, this qualitative study describes the social context of API undocumented young adults (ages 18-31), including community and government perceptions, and how social relationships influence health...

The demand for semiconductor indium oxide (In2O3) nanocrystals is increasing because of their diverse applications, including in biomedicine. However, there is a scarcity of studies on the biological interaction of indium oxide nanocrystals. Here, we explored the underlying mechanisms of toxicity induced by indium oxide nanocubes in human lung epithelial (A549) cells. Prepared indium oxide nanocubes were crystalline with an average size of 21nm. Biointeraction studies have shown that indium oxide nanocubes induce cell viability reduction and cell membrane damage in a dose- and time-dependent manner...

Plumieride, an iridoid glucoside isolated from Plumieria acutifolia leaves was investigated for its immunostimulatory activity on humoral, cell mediated and intracellular cytokine levels in sensitized and unsensitised balb/c mice. Plumieride restores the suppressed cell mediated, humoral immune response and also enhances the release of TNF- α, IFN-γ, and IL-2 (Th-1) in immune compromised cyclosporine and cyclophosphamide treated balb/c mice. It does not stimulate the IL-4 (Th-2) expression. Plumieride demonstrates significant augmentation of Th-1 response in immunosuppressed balb/c mice...

Mast cells play crucial roles in the initiation of allergic inflammatory responses by releasing various mediators such as histamines, cytokines, and leukotrienes. In addition, signaling cascade pathways, such as the mitogen-activated protein kinase (MAPK) pathway, contribute to the regulation of mast cell degranulation. Accordingly, different research strategies have been pursued to develop anti-inflammatory and anti-allergic drugs by regulating these signaling pathways. The development of new drugs that inhibit mast cell degranulation may help in the treatment of allergies...
