Abstract
BACKGROUND Exposure to adverse experiences during pregnancy, such as a natural disaster, can modify development of the child with potential long-term consequences. Elemental hair analysis may provide useful indicators of cellular homeostasis and child health. The present study investigated (1) if flood-induced prenatal maternal stress is associated with altered hair elemental profiles in 4-year-old children, and (2) if hair elemental profiles are associated with behavioural outcomes in children. METHODS Participants were 75 children (39 boys; 36 girls) whose mothers were exposed to varying levels of stress due to a natural disaster (2011 Queensland Flood, Australia) during pregnancy. At 4 years of age, language development, attention and internalizing and externalizing problems were assessed and scalp hair was collected. Hair was analyzed by inductively coupled plasma mass spectrometry (ICP-MS) for 28 chemical elements. RESULTS A significant curvilinear association was found between maternal objective hardship and copper levels in boys, as low and high maternal objective hardship levels were associated with the highest hair copper levels. Mediation analysis revealed that low levels of maternal objective hardship and high levels of copper were associated with lower vocabulary scores. Higher levels of maternal objective hardship were associated with higher magnesium levels, which in turn were associated with attention problems and aggression in boys. In girls, high and low maternal objective hardship levels were associated with high calcium/potassium ratios. CONCLUSION Elemental hair analysis may provide a sensitive biomonitoring tool for early identification of health risks in vulnerable children.

Abstract
Mature mRNA molecules are expected to be comprised of a 5’UTR, a 3’UTR and a coding region (CDS). Unexpectedly, however, there have been multiple recent reports of widespread differential expression of mRNA 3’UTRs and their cognate coding regions (CDS), reflecting the expression of isolated 3’UTRs (i3’UTRs); these i3’UTRs can be highly expressed, often in reciprocal patterns to their cognate CDS. As with other long non-coding (lncRNAs), isolated 3’UTRs are likely to play an important role in gene regulation, but little is known about the contexts in which they are deployed. To illuminate the functions of i3’UTRs, here we carry out in vitro, in vivo and in silico analyses of differential 3’UTR/CDS mRNA ratio usage across tissues, development and cell state changes both for a select list of developmentally important genes as well as by unbiased transcriptome-wide analyses. Across two developmental paradigms we find a distinct switch from high i3’UTR expression for stem cell related genes in proliferating cells to high CDS for these genes in newly differentiated cells. Unbiased transcriptome analysis across multiple gene sets shows that regardless of tissue, genes with high 3’UTR to CDS ratios belong predominantly to gene ontology categories related to cell-type specific functions. In contrast, the gene ontology categories of genes with low 3’UTR to CDS ratios are similar across tissues and relate to common cellular functions. We further show that, at least for some genes, traditional transcriptional start site genomic elements correspond to identified RNAseq 3’UTR peak regions, suggesting that some i3’UTRs may be generated by de novo transcription. Our results provide critical information from which detailed hypotheses for individual i3’UTRs can be tested, with a common theme that i3’UTRs appear poised to regulate cell-specific gene expression and state.

Abstract
Adult stem cells commonly give rise to transit-amplifying progenitors, whose progeny differentiate into distinct cell types. It is unclear if stem cell niche signals coordinate fate decisions within the progenitor pool. Here we use quantitative analysis of Wnt, Hh, and Notch signalling reporters and the cell fate markers Eyes Absent (Eya) and Castor (Cas) to study the effects of hyper-activation and loss of niche signals on progenitor development in the Drosophila ovary. Follicle stem cell (FSC) progeny adopt distinct polar, stalk, and main body cell fates. We show that Wnt signalling transiently inhibits expression of the main body cell fate determinant Eya, and Wnt hyperactivity strongly biases cells towards polar and stalk fates. Hh signalling independently controls the proliferation to differentiation transition. Notch is permissive but not instructive for differentiation of multiple cell types. These findings reveal that multiple niche signals coordinate cell fates and differentiation of progenitor cells.

Abstract
In an effort to find new and safer treatments for osteoporosis and frailty, we describe a novel series of selective androgen receptor modulators (SARMs). Using a structure-based approach, we identified compound 7, a potent AR (ARE EC50 = 0.34 nM) and selective (N/C interaction EC50 = 1206 nM) modulator. In vivo data, an AR LBD X-ray structure of 7, and further insights from modeling studies of ligand receptor interactions are also presented.

Abstract
BACKGROUND HIV-infected persons have less robust antibody responses to influenza vaccines. OBJECTIVE To compare the immunogenicity of high-dose influenza vaccine with that of standard dosing in HIV-positive participants. DESIGN Randomized, double-blind, controlled trial. (ClinicalTrials.gov: NCT01262846) SETTING The MacGregor Clinic of the Hospital of the University of Pennsylvania, Philadelphia, from 27 October 2010 to 27 March 2011. PARTICIPANTS HIV-infected persons older than 18 years. INTERVENTION Participants were randomly assigned to receive either a standard dose (15 mcg of antigen per strain) or a high dose (60 mcg/strain) of the influenza trivalent vaccine. MEASUREMENTS The primary end point was the rate of seroprotection, defined as antibody titers of 1:40 or greater on the hemagglutination inhibition assay 21 to 28 days after vaccination. The primary safety end point was frequency and intensity of adverse events. Secondary end points were seroconversion rate (defined as a greater than 4-fold increase in antibody titers) and the geometric mean antibody titer. RESULTS 195 participants enrolled, and 190 completed the study (93 in the standard-dose group and 97 in the high-dose group). The seroprotection rates after vaccination were higher in the high-dose group for the H1N1 (96% vs. 87%; treatment difference, 9 percentage points [95% CI, 1 to 17 percentage points]; P = 0.029), H3N2 (96% vs. 92%; treatment difference, 3 percentage points [CI, -3 to 10 percentage points]; P = 0.32), and influenza B (91% vs. 80%; treatment difference, 11 percentage points [CI, 1 to 21 percentage points]; P = 0.030) strains. Both vaccines were well-tolerated, with myalgia (19%), malaise (14%), and local pain (10%) the most frequent adverse events. LIMITATIONS The effectiveness of the vaccine in preventing clinical influenza was not evaluated. The number of participants with CD4 counts less than 0.200 × 109 cells/L was limited. CONCLUSION HIV-infected persons reach higher levels of influenza seroprotection if vaccinated with the high-dose trivalent vaccine than with the standard-dose.

Abstract
Androgenetic alopecia (AGA), commonly known as male pattern baldness, is a form of hair loss that occurs in both males and females. Although the exact cause of AGA is not known, it is associated with genetic predisposition through traits related to androgen synthesis/metabolism and androgen signaling mediated by the androgen receptor (AR). Current therapies for AGA show limited efficacy and are often associated with undesirable side effects. A major hurdle to developing new therapies for AGA is the lack of small animal models to support drug discovery research. Here, we report the first rodent model of AGA. Previous work demonstrating that the interaction between androgen-bound AR and beta-catenin can inhibit Wnt signaling led us to test the hypothesis that expression of AR in hair follicle cells could interfere with hair growth in an androgen-dependent manner. Transgenic mice overexpressing human AR in the skin under control of the keratin 5 promoter were generated. Keratin 5-human AR transgenic mice exposed to high levels of 5alpha-dihydrotestosterone showed delayed hair regeneration, mimicking the AGA scalp. This effect is AR mediated, because treatment with the AR antagonist hydroxyflutamide inhibited the effect of dihydrotestosterone on hair growth. These results support the hypothesis that androgen-mediated hair loss is AR dependent and suggest that AR and beta-catenin mediate this effect. These mice can now be used to test new therapeutic agents for the treatment of AGA, accelerating the drug discovery process.

Abstract
Pathway selective ligands of the estrogen receptor inhibit transcriptional activation of proinflammatory genes mediated by NF-kappaB. Substituted 2-cyanopropanoic acid derivatives were developed leading to the discovery of WAY-204688, an orally active, pathway selective, estrogen receptor dependent anti-inflammatory agent. This propanamide was shown to be orally active in preclinical models of inflammatory diseases, such as rheumatoid arthritis, without the proliferative effect associated with traditional estrogens.

Abstract
We previously reported on the development of a pathway-selective estrogen receptor (ER) ligand, WAY-169916, that has ER-dependent antiinflammatory activity and is devoid of classic ER transcriptional activity. In the current study, WAY-169916 and 17beta-estradiol (17beta-E2) were evaluated for protective activity in models of cardiac ischemia-reperfusion injury. In rats subjected to cardiac ischemia-reperfusion injury by occlusion of the left coronary artery, infarct size relative to the area at risk in the left ventricle was significantly attenuated by a single dose of 17beta-E2 (20 microg/kg, SC), and WAY-169916 administered SC (10 mg/kg) or IV (1 mg/kg) during the ischemia phase. In isolated hearts perfused on a Langendorff apparatus and subjected to global ischemia and reperfusion, 17beta-E2 and WAY-169916 both had direct cardioprotective activity when perfused at 1 microM but their effects varied between different end points. Perfusion with 17beta-E2 only improved recovery of left ventricle-developed pressure. Perfusion with WAY-169916 attenuated the elevation in perfusion pressure, diastolic pressure, and release of creatine kinase after ischemia. In contrast to 17alpha-ethinylestradiol, WAY-169916 had no classic estrogen effects on uterine weight or total serum cholesterol in rats treated for 4 days. The data demonstrate that the pathway-selective ER ligand WAY-169916 displays differential activity in vivo on different cardiovascular end points.

Abstract
The discovery of novel intervention points in the inflammatory pathway has been a focus of drug development in recent years. We have identified pathway selective ligands for the estrogen receptor (ER) that inhibit NF-kappaB mediated inflammatory gene expression causing a reduction of cytokines, chemokines, adhesion molecules and inflammatory enzymes. SAR development of a series of 4-(Indazol-3-yl)-phenols has led to the identification of WAY-169916 an orally active non-steroidal ligand with the potential use in the treatment of inflammatory diseases without the classical proliferative effects associated with non-selective estrogens.

Abstract
The Internet is a repository of information unparalleled in history. The abundance of published material about prostate cancer has never been greater. Couple this with burgeoning pharmaceutical public-relations budgets and the result is a bewildering maze of hundreds of thousands of prostate cancer-oriented Internet pages. Our purposes are to help practitioners understand the profound handicap that patients are faced with when they attempt to search the Internet for information about their newly diagnosed disease and to succinctly evaluate the presence or absence of key aspects of prostate cancer on some of the most easily accessible sites. Part two of this paper will then discuss 4 of the most valuable Web sites for the prostate cancer specialist. Surfing the World Wide Web can be frustrating and time-consuming, but it can also be rewarding and informative.

Abstract
Previous in vitro work demonstrated the incorporation of the major inducible 70k heat shock protein (i.e., 72k HSP) into the biologically active light nucleocapsid (L-NC) variant of canine distemper virus (CDV). Here, in vitro induction of the cellular stress response, characterized by elevated cytoplasmic and intranuclear 72k HSP, enhanced L-NC expression in mink lung cells supporting stable persistent infection by raccoon-origin CDV. Increases in L-NC were correlated to increased viral RNA production in cell-free transcriptional assays. The enhanced production of viral transcripts within infected cells following stress response induction was confirmed by slot blot and Northern blot analysis of total cellular RNA and was reflected in increased total viral protein production. Post-shock increases in viral fusion (F) gene transcripts and F protein were associated with dramatic increases in viral cytopathic effect. Modest induction of cell-free infectious viral progeny was also documented. A similar effect of the cellular stress response upon viral protein expression, cytopathic effect, and cell-free infectious progeny release was demonstrated in murine neuroblastoma cells persistently infected with a canine CDV isolate. Alterations of the persistent viral phenotype were independent of the specific mechanism of stress-response induction (i.e., heat or sodium arsenite), supporting the role of the stress response and not a particular stressor in mediating these changes. These results document the ability of the cellular environment to alter persistent viral RNA metabolism, thereby altering the infection phenotype.
