Interferon gamma is not required for recurrent herpetic stromal keratitis.
The role that interferon-gamma (IFNgamma) plays during herpetic stromal keratitis (HSK) has not been definitively determined. In primary HSK most reports suggest that IFNgamma may help control viral replication and contribute to corneal pathology. However, its role in recurrent HSK has not been directly addressed. The ...

Animal models of anxiety: do I need multiple tests?
The combination of cutting-edge molecular technology and high-throughput phenotyping tools will not bring the expected contribution to the pre-clinical study of anxiety if not paralleled by an increase in our capacity to interpret behavioral data. Here, previous views about the multidimensional nature of emotional beha...

The use of scoring rubrics to determine clinical performance in the operating suite.
This research evolved out of the need to examine the validity and inter-rater reliability of a set of performance-based scoring rubrics designed to measure competencies within the operating suite. Both holistic and analytical rubrics were developed aligned to the ACORN Standard [Australian College of Operating Room Nur...

Acaricidal activity of limonene, limonene oxide and beta-amino alcohol derivatives on Rhipicephalus (Boophilus) microplus.
Limonene, limonene oxide and eight beta-amino alcohol derivatives obtained by synthesis were investigated for the effect on egg hatchability and mortality rates of newly hatched larvae of the cattle tick Rhipicephalus (Boophilus) microplus. At the doses between 10 microg/ml and 2.5 microg/ml all the compounds were high...

Bolstering confidence in obesity prevention and treatment counseling for resident and community pediatricians.
To assess whether equipping resident pediatricians and community pediatricians with both training and practical tools improves their perceived confidence, ease, and frequency of obesity-related counseling to patients. In 2005-2006, resident pediatricians (n = 49) and community pediatricians (n = 18) received training r...

Design and synthesis of fluorescent SGLT2 inhibitors.
The design and synthesis of the first fluorophore-conjugated SGLT2 inhibitors is described. The mode of linking the fluorophore to the SGLT2 pharmacophore was found to be crucial in achieving optimum potency. Superior potency to phlorizin was provided by examples containing TAMRA, BODIPY, Cy3B and NBD fluorophores.

Discovery of thieno[2,3-c]pyridines as potent COT inhibitors.
Evaluation of hit chemotypes from high throughput screening identified a novel series of 2,4-disubstituted thieno[2,3-c]pyridines as COT kinase inhibitors. Structural modifications exploring SAR at the 2- and 4-positions resulting in inhibitors with improved enzyme potency and cellular activity are disclosed.

Structure-guided design of substituted aza-benzimidazoles as potent hypoxia inducible factor-1alpha prolyl hydroxylase-2 inhibitors.
We report the structure-based design and synthesis of a novel series of aza-benzimidazoles as PHD2 inhibitors. These efforts resulted in compound 22, which displayed highly potent inhibition of PHD2 function in vitro.

[Interests of applied anthropology to oncology].
From now on the introduction of social and human sciences studies in the field of oncology has not always been conclusive. This article aims to analyze the bounds that border the meeting and the understanding between physicians, patients and anthropologists. It also treats the problems due to the introduction of applie...

Methane emissions by alpine plant communities in the Qinghai-Tibet Plateau.
For the first time to our knowledge, we report here methane emissions by plant communities in alpine ecosystems in the Qinghai-Tibet Plateau. This has been achieved through long-term field observations from June 2003 to July 2006 using a closed chamber technique. Strong methane emission at the rate of 26.2+/-1.2 and 7....

Moving with the beat: heart rate and visceral temperature of free-swimming and feeding bluefin tuna.
Owing to the inherent difficulties of studying bluefin tuna, nothing is known of the cardiovascular function of free-swimming fish. Here, we surgically implanted newly designed data loggers into the visceral cavity of juvenile southern bluefin tuna (Thunnus maccoyii) to measure changes in the heart rate (fH) and viscer...

Iron-mediated aggregation and a localized structural change characterize ferritin from a mutant light chain polypeptide that causes neurodegeneration.
Nucleotide insertions in the ferritin light chain (FTL) polypeptide gene cause hereditary ferritinopathy, a neurodegenerative disease characterized by abnormal accumulation of ferritin and iron in the central nervous system. Here we describe for the first time the protein structure and iron storage function of the FTL ...

Promoting the formation of an active synthetase/tRNA complex by a nonspecific tRNA-binding domain.
Previous studies showed that valyl-tRNA synthetase of Saccharomyces cerevisiae contains an N-terminal polypeptide extension of 97 residues, which is absent from its bacterial relatives, but is conserved in its mammalian homologues. We showed herein that this appended domain and its human counterpart are both nonspecifi...

Vibrio cholerae O1 from Accra, Ghana carrying a class 2 integron and the SXT element.
Vibrio cholerae O1 from a 2006 outbreak in Accra were commonly resistant to multiple antimicrobials and, in particular, to trimethoprim/sulfamethoxazole, drugs commonly used in the treatment of cholera. We sought to determine the genetic basis for trimethoprim/sulfamethoxazole resistance in outbreak isolates. Twenty-se...

Tissues from routine pathology archives are suitable for microRNA analyses by quantitative PCR.
MicroRNAs have recently taken centre stage as short non-coding RNAs that regulate mRNA expression. To assess the feasibility of using microRNA techniques on routinely processed tissues, the accessibility of two representative microRNAs was examined by real-time quantitative PCR in 86 human formalin-fixed paraffin-embed...

Failure of first-line eradication treatment significantly increases prevalence of antimicrobial-resistant Helicobacter pylori clinical isolates.
Helicobacter pylori infection is a major health problem worldwide, and effective eradication of the infection is mandatory. The efficacy of recommended eradication regimens is approximately 70%. To avoid treatment failure and the consequent development of secondary resistance(s), it is important to choose the most appr...

Abatement by naringin of lomefloxacin-induced genomic instability in mice.
Lomefloxacin is a difluorinated quinolone antibacterial drug. It is widely used against infectious diseases including meningitis, those of the genitourinary and upper respiratory tracts, and skin infections. Lomefloxacin, like other fluoroquinolones, is mutagenic and the formation of reactive oxygen species appears to ...

In vivo birthdating by BAPTISM reveals that trigeminal sensory neuron diversity depends on early neurogenesis.
Among sensory systems, the somatic sense is exceptional in its ability to detect a wide range of chemical, mechanical and thermal stimuli. How this sensory diversity is established during development remains largely elusive. We devised a method (BAPTISM) that uses the photoconvertible fluorescent protein Kaede to simul...

Genes associated with membrane-initiated signaling of estrogen and energy homeostasis.
During the reproductive cycle, fluctuations in circulating estrogens affect multiple homeostatic systems controlled by hypothalamic neurons. Two of these neuronal populations are arcuate proopiomelanocortin and neuropeptide Y neurons, which control energy homeostasis and feeding. Estradiol modulates these neurons eithe...

Modulation of Runx2 activity by estrogen receptor-alpha: implications for osteoporosis and breast cancer.
The transcription factors Runx2 and estrogen receptor-alpha (ERalpha) are involved in numerous normal and disease processes, including postmenopausal osteoporosis and breast cancer. Using indirect immunofluorescence microscopy and pull-down techniques, we found them to colocalize and form complexes in a ligand-dependen...

Transcriptome response of enterocytes to dietary lipids: impact on cell architecture, signaling, and metabolism genes.
Intestine contributes to lipid homeostasis through the absorption of dietary lipids, which reach the apical pole of enterocytes as micelles. The present study aimed to identify the specific impact of these dietary lipid-containing micelles on gene expression in enterocytes. We analyzed, by microarray, the modulation of...
