A straightforward synthesis of l-lyxo- and l-xylo-phytosphingosine along with their isomeric analogues has been accomplished. The salient features of this approach are the utilization of [3,3]-sigmatropic rearrangements to install a C-N bond and application of a late stage Wittig or OCM reaction to incorporate the hydrophobic chain unit. The final compounds were evaluated regarding their ability to alter both leukaemia and solid tumor cancer cells viability.

INTRODUCTION: Recent studies have shown that sclerostin, which is a negative regulator of bone formation, could play an important role in the crosstalk between bone and glucose metabolism. The role of sclerostin and its link with glucose homeostasis in type 1 diabetes mellitus (T1D) has not been yet studied extensively in children. The aim of this study was to assess sclerostin and its relationship between other bone and fat related factors as well as glucose metabolism in children and adolescents with T1D in comparison to their healthy peers...

1.Early arrival at breeding grounds is of prime importance for migrating birds as it is known to enhance breeding success. Adults, males and higher quality individuals typically arrive earlier, and across years, early arrival has been linked to warmer spring temperatures. However, the mechanisms and potential costs of early arrival are not well understood. 2.To deepen the understanding of arrival date differences between individuals and years, we studied them in light of the preceding spring migration behaviour and atmospheric conditions en route...

Copaifera (Leguminoseae) species produce a commercially interesting oleoresin that displays several biological activities, including antimicrobial and anti-inflammatory properties. Labdane-type diterpenes are the main chemical constituents of these oleoresins, and copalic acid is the only compound that has been detected in all Copaifera oleoresins. In this study, we investigate some aspects of the gas-phase fragmentation reactions involved in the formation of the product ions from the deprotonated compounds (-)-copalic acid (1), (-)-3β-hydroxy-copalic acid (2), (-)-3β-acetoxy-copalic acid (3), and (-)-ent-agathic acid (4) by electrospray ionization tandem mass spectrometry (ESI-MS/MS) and multiple stage mass spectrometry (MSn )...

BACKGROUND: In recent years there has been a surge in the number of commercially available lactose-free variants of a wide variety of products. This presents an analytical challenge for the measurement of the residual lactose content in the presence of high levels of mono-, di-, and oligosaccharides. RESULTS: In the current work, we describe the development of a novel enzymatic low-lactose determination method termed LOLAC which is based on an optimised glucose removal pre-treatment step followed by a sequential enzymatic assay which measures residual glucose and lactose in a single cuvette...

Faith and public health partnerships offer promise to addressing health disparities, but examples that incorporate African-Americans and Latino congregations are lacking. Here we present results from developing a multi-ethnic, multi-denominational faith and public health partnership to address health disparities through community-based participatory research (CBPR), focusing on several key issues: (1) the multi-layered governance structure and activities to establish the partnership and identify initial health priority (obesity), (2) characteristics of the congregations recruited to partnership (n = 66), and (3) the lessons learned from participating congregations' past work on obesity that informed the development of a multi-level, multi-component, church-based intervention...

PURPOSE: The methods (IHC/FISH) typically used to assess ER, PR, HER2, and Ki67 in FFPE specimens from breast cancer patients are difficult to set up, perform, and standardize for use in low and middle-income countries. Use of an automated diagnostic platform (GeneXpert®) and assay (Xpert® Breast Cancer STRAT4) that employs RT-qPCR to quantitate ESR1, PGR, ERBB2, and MKi67 mRNAs from formalin-fixed, paraffin-embedded (FFPE) tissues facilitates analyses in less than 3 h. This study compares breast cancer biomarker analyses using an RT-qPCR-based platform with analyses using standard IHC and FISH for assessment of the same biomarkers...

Roles are one of the most important concepts in understanding human sociocognitive behavior. During group interactions, members take on different roles within the discussion. Roles have distinct patterns of behavioral engagement (i.e., active or passive, leading or following), contribution characteristics (i.e., providing new information or echoing given material), and social orientation (i.e., individual or group). Different combinations of roles can produce characteristically different group outcomes, and thus can be either less or more productive with regard to collective goals...
