Just as containerized goods appear to flow seamlessly across the planet’s oceans, internationalized and standardized certificates present seafaring labor uniform seamless. But underneath these are intimate unequal entanglements of local masculinity norms, age, kinship ties that sustain maritime supply chain. In this article, we follow how three young, male seafarers from eastern India find ways...

its daughter cells differentiate like MS and no longer produce gut (Goldstein 1993). Further nongenetic ma-Department of Molecular, Cellular, and Developmental Biology nipulations of cultured embryonic cells have demonstrated that P 2 is the source of this signal and that the University of Colorado Boulder, Colorado 80309-0347 position of P 2 relative to EMS determines which daughter of EMS pro...

OBJECTIVE To examine the distribution of first-trimester biochemical markers of aneuploidy in twin pregnancies, and to assess whether there are differences in the distributions between monochorionic and dichorionic twins. METHODS Maternal serum-free beta-hCG and PAPP-A were measured between 11 + 0 and 13 + 6 weeks as part of a routine first-trimester screening program in conjunction with feta...

Parameter estimation for the K distribution is an essential part of the statistical analysis of non-Rayleigh sonar reverberation or clutter for performance prediction, estimation of scattering properties, and for use in signal and information processing algorithms. Computational issues associated with maximum likelihood (ML) estimation techniques for K-distribution parameters often force the us...

Tail-anchored (TA) proteins have a single C-terminal transmembrane domain, making their biogenesis dependent on posttranslational translocation. Despite their importance, no dedicated insertion machinery has been uncovered for mitochondrial outer membrane (MOM) TA proteins. To decipher the molecular mechanisms guiding MOM TA protein insertion, we performed two independent systematic microscopic...

The aim of our study was to evaluate the middle cerebral artery velocimetry before and after intrauterine blood transfusion in immune hydrops fetalis. The current study was conducted in a tertiary research hospital, from February 2009 to January 2011. Nineteen intrauterine blood transfusions performed during the study period. The factors recorded were age of the mothers, gestational weeks, pre-...

OBJECTIVE To investigate whether the maternal serum concentration of placental protein 13 (PP13) is altered in chromosomally abnormal pregnancies and to examine the potential value of this placental protein in screening for aneuploidies at 11-13 weeks. METHODS The maternal serum concentration of PP13 at 11-13 weeks was compared in 536 euploid and 134 aneuploid pregnancies (trisomy 21: n = 49;...
