An Open-Label Pilot Study of Duloxetine in Patients With Irritable Bowel Syndrome and Comorbid Major Depressive Disorder.

Major depressive disorder (MDD) and irritable bowel syndrome (IBS) frequently co-occur, yet treating their comorbid presentation is challenging. Low-dose tricyclic antidepressants are efficacious for IBS, but higher doses to treat depressive symptoms present tolerability problems, whereas selective serotonin reuptake inhibitors are more tolerable but show inconsistent efficacy for IBS. If efficacious, serotonin-norepinephrine reuptake inhibitors like duloxetine would provide a useful alternative.

Toward a cultural adaptation of pharmacotherapy: Latino views of depression and antidepressant therapy.

Relative to non-Latino Whites, Latinos in the United States with major depressive disorder (MDD) show low engagement in antidepressant therapy, whether engagement is defined as pharmacotherapy access, medication initiation, pill-taking, or treatment retention. One potential reason for this disparity in depression care is the low cultural congruence of pharmacotherapy for this population. To examine Latinos' views of depression and antidepressant therapy, we conducted qualitative interviews with 30 Latino outpatients initiating antidepressants prior to their first treatment visit using the semistructured Treatment Adherence and Retention Questionnaire.

Potential epigenetic dysregulation of genes associated with MODY and type 2 diabetes in humans exposed to a diabetic intrauterine environment: an analysis of genome-wide DNA methylation.

Objective: The aim of this study is to investigate the potential role of DNA methylation in mediating the increased risk of developing type 2 diabetes in offspring of mothers who had diabetes during pregnancy.

Materials And Methods: Peripheral blood leukocytes were collected from non-diabetic Pima Indians who were either offspring of diabetic mothers (ODM; n=14) or offspring of nondiabetic mothers (ONDM; n=14). The two groups were matched for age, sex, age of mother, and fraction of Pima ethnicity.

Whole exome sequencing identifies variation in CYB5A and RNF10 associated with adiposity and type 2 diabetes.

Objective: Few coding variants in genes associated with type 2 diabetes (T2D) have been identified, and the underlying physiologic mechanisms whereby susceptibility genes influence T2D risk are often unknown. The objective of this study was to identify coding variation that increases risk for T2D via an effect on a pre-diabetic trait.

Methods: Whole exome sequencing was done in 177 Pima Indians.

β-Puromycin selection of modified ribosomes for in vitro incorporation of β-amino acids.

Ribosomally mediated protein biosynthesis is limited to α-L-amino acids. A strong bias against β-L-amino acids precludes their incorporation into proteins in vivo and also in vitro in the presence of misacylated β-aminoacyl-tRNAs. Nonetheless, earlier studies provide some evidence that analogues of aminoacyl-tRNAs bearing β-amino acids can be accommodated in the ribosomal A-site.

The crystal structure of auracyanin A at 1.85 A resolution: the structures and functions of auracyanins A and B, two almost identical "blue" copper proteins, in the photosynthetic bacterium Chloroflexus aurantiacus.

Auracyanins A and B are two closely similar "blue" copper proteins produced by the filamentous anoxygenic phototrophic bacterium Chloroflexus aurantiacus. Both proteins have a water-soluble 140-residue globular domain, which is preceded in the sequence by an N-terminal tail. The globular domains of auracyanins A and B have sequences that are 38% identical.

Cellular apoptosis and cytotoxicity of phenolic compounds: a quantitative structure-activity relationship study.

In this comprehensive study on the caspase-mediated apoptosis-inducing effect of 51 substituted phenols in a murine leukemia cell line (L1210), we determined the concentrations needed to induce caspase activity by 50% (I50) and utilized these data to develop the following quantitative structure-activity relationship (QSAR) model: log 1/I50 = 1.06 B5(2) + 0.33 B5(3) - 0.

New class of bacterial membrane oxidoreductases.

A new class of bacterial multisubunit membrane-bound electron-transfer complexes has been identified based on biochemical and bioinformatic data. It contains subunits homologous to the three-subunit molybdopterin oxidoreductases and four additional subunits, two of which are c-type cytochromes. The complex was purified from the filamentous anoxygenic phototrophic bacterium Chloroflexus aurantiacus, and putative operons for similar complexes were identified in a wide range of bacteria.
