A machine vision system for automated non-invasive assessment of cell viability via dark field microscopy, wavelet feature selection and classification.
Cell viability is one of the basic properties indicating the physiological state of the cell, thus, it has long been one of the major considerations in biotechnological applications. Conventional methods for extracting information about cell viability usually need reagents to be applied on the targeted cells. These rea...

12/15-Lipoxygenase regulates the inflammatory response to bacterial products in vivo.
The peritoneal macrophage (Mphi) is the site of greatest 12/15-lipoxygenase (12/15-LOX) expression in the mouse; however, its immunoregulatory role in this tissue has not been explored. Herein, we show that 12/15-LOX is expressed by 95% of resident peritoneal CD11b(high) cells, with the remaining 5% being 12/15-LOX(-)....

Differential regulation of chemokines by IL-17 in colonic epithelial cells.
The IL-23/IL-17 pathway plays an important role in chronic inflammatory diseases, including inflammatory bowel disease. In inflammatory bowel disease, intestinal epithelial cells are an important source of chemokines that recruit inflammatory cells. We examined the effect of IL-17 on chemokine expression of HT-29 colon...

Activation of an immunoregulatory and antiviral gene expression program in poly(I:C)-transfected human neutrophils.
Neutrophils, historically known for their involvement in acute inflammation, are also targets for infection by many different DNA and RNA viruses. However, the mechanisms by which they recognize and respond to viral components are poorly understood. Polyinosinic:polycytidylic acid (poly(I:C)) is a synthetic mimetic of ...

Issues in the measurement of social determinants of health.
This article focuses on the measurement of the social determinants of health, and specifically on issues relating to two key variables relevant to the analysis of public health information: poverty and inequality. Although the paper has been written from the perspective of economics, the discipline of the two authors, ...

Discovery and synthetic applications of novel silicon-carbon bond cleavage reactions based on the coordination number change of organosilicon compounds.
Some synthetically useful transformations of organosilicon compounds have been developed since the mid 1970s, based on the new concept that the silicon-carbon bonds are activated toward electrophilic cleavage via the formation of penta- and hexa-coordinate species. This review mainly consists of the following aspects: ...

Assessment of renal function in elderly patients.
The proportion of elderly individuals is growing rapidly in all societies and the incidence of chronic kidney disease among elderly people increases constantly. Accurate monitoring of kidney function, that is, glomerular filtration rate, in elderly people is therefore of considerable clinical interest in order to detec...

Asymmetric dimethylarginine: a novel marker of risk and a potential target for therapy in chronic kidney disease.
Asymmetric dimethylarginine (ADMA) is a naturally occurring amino acid that reduces the bioavailability of nitric oxide. ADMA opposes important antiatherosclerotic effects of nitric oxide. ADMA not only correlates with traditional and nontraditional risk factors but is also considered a common pathway mediating the adv...

Mullerian adenosarcoma: a clinicopathologic and immunohistochemical study of 55 cases challenging the existence of adenofibroma.
Mullerian adenosarcomas are rare mixed tumors of low malignant potential that occur mainly in the uterus and also in extrauterine locations. Microscopically, they may be difficult to distinguish from adenofibromas. In this clinicopathologic study of 55 adenosarcomas, the mean patient age was 50 years (range: 13 to 83 y...

Increased apparent diffusion coefficients on MRI linked with matrix metalloproteinases and edema in white matter after bilateral carotid artery occlusion in rats.
White matter (WM) injury after bilateral common carotid artery occlusion (BCAO) in rat is associated with disruption of the blood-brain barrier (BBB) by matrix metalloproteinases (MMPs). We hypothesized that WM injury as seen on magnetic resonance imaging (MRI) would correlate with regions of increased MMP activity. MR...

Decline of melanism in two British moths: spatial, temporal and inter-specific variation.
The decline in industrial melanism over the last quarter century constitutes an exceptional case of an evolutionary change, varying in both time and space, and between species. In Biston betularia and Odontoptera bidentata, the change in melanic frequency is closely replicated at two sites 0.5 km apart. Between seven s...

Enantioselective nucleophilic difluoromethylation of aromatic aldehydes with Me3SiCF2SO2Ph and PhSO2CF2H reagents catalyzed by chiral quaternary ammonium salts.
Although the nucleophilic difluoromethylation of aldehydes, ketones, and imines has been realized with PhSO(2)CF(2)H and related reagents, there are still no reports on the enantioselective nucleophilic reactions. With a chiral quaternary ammonium salt as the catalyst and KOH as the base, we describe the first enantios...

Long lasting persistence of Bacillus thuringiensis Subsp. israelensis (Bti) in mosquito natural habitats.
The detrimental effects of chemical insecticides on the environment and human health have lead to the call for biological alternatives. Today, one of the most promising solutions is the use of spray formulations based on Bacillus thuringiensis subsp. israelensis (Bti) in insect control programs. As a result, the amount...

Glucose uptake and its effect on gene expression in prochlorococcus.
The marine cyanobacteria Prochlorococcus have been considered photoautotrophic microorganisms, although the utilization of exogenous sugars has never been specifically addressed in them. We studied glucose uptake in different high irradiance- and low irradiance-adapted Prochlorococcus strains, as well as the effect of ...

Diaphanous-related formin 2 and profilin I are required for gastrulation cell movements.
Intensive cellular movements occur during gastrulation. These cellular movements rely heavily on dynamic actin assembly. Rho with its associated proteins, including the Rho-activated formin, Diaphanous, are key regulators of actin assembly in cellular protrusion and migration. However, the function of Diaphanous in gas...

Functional dorsoventral symmetry in relation to lift-based swimming in the ocean sunfish Mola mola.
The largest (up to 2 tons) and a globally distributed teleost--the ocean sunfish Mola mola--is commonly regarded as a planktonic fish because of its unusual shape including absence of caudal fin. This common view was recently questioned because the horizontal movements of the ocean sunfish tracked by acoustic telemetry...

Mycolactone diffuses from Mycobacterium ulcerans-infected tissues and targets mononuclear cells in peripheral blood and lymphoid organs.
Buruli ulcer (BU) is a progressive disease of subcutaneous tissues caused by Mycobacterium ulcerans. The pathology of BU lesions is associated with the local production of a diffusible substance, mycolactone, with cytocidal and immunosuppressive properties. The defective inflammatory responses in BU lesions reflect the...

Extended driving impairs nocturnal driving performances.
Though fatigue and sleepiness at the wheel are well-known risk factors for traffic accidents, many drivers combine extended driving and sleep deprivation. Fatigue-related accidents occur mainly at night but there is no experimental data available to determine if the duration of prior driving affects driving performance...

Does the committee peer review select the best applicants for funding? An investigation of the selection process for two European molecular biology organization programmes.
Does peer review fulfill its declared objective of identifying the best science and the best scientists? In order to answer this question we analyzed the Long-Term Fellowship and the Young Investigator programmes of the European Molecular Biology Organization. Both programmes aim to identify and support the best post d...

Role of alphaBI5 and alphaBT162 residues in subunit interaction during oligomerization of alphaB-crystallin.
To determine whether the residues in the NH(2)- and COOH-terminal extensions interact with one another during oligomerization of alphaB-crystallin. Site-directed mutagenesis was used to mutate alphaBI5 and alphaBT162 residues to Cys. The recombinant I5C and T162C proteins were expressed in Escherichia coli cells and pu...
