Abstract
Gene therapy as a treatment for neuromuscular diseases is an ever-developing concept based on the use of DNA as the therapeutic agent. In the search for appropriate strategies a bottleneck exists, however, concerning the targeting of vectors carrying the therapeutic gene, to all pathologic sites. These diseases are often characterised by multiple widespread lesions spread over a large area, rendering administration by local injection into tissues, clinically irrelevant. With this in mind, we have proposed that circulating cells (monocytes/macrophages), which home naturally to inflammatory lesions, characteristic of degenerating muscle, could be used as shuttles able to track down every damaged site, and deliver there a corrective gene. Our aim is to mobilise a corrective gene from these infiltrating monocyte-macrophages, into muscle cells, a process of in situ cell to cell gene transfer which could be accomplished using a retroviral vector, since the regeneration process involves the proliferation of muscle precursors before they fuse to form replacement fibres. For this, monocyte-macrophages must be engineered into 'packaging cells' containing both the replication deficient retrovirus carrying the gene of interest and an helper genome (gag-pol-env) needed for its assembly and secretion. Here, we have transduced a monocyte cell line using a defective murine Moloney leukemia retrovirus carrying the LacZ reporter gene. This provided us with a platform to investigate the possibility of gag-pol-env vector driven packaging of the defective retrovirus by macrophages. We show that an herpes simplex virus type I amplicon harbouring the Moloney gag, pol, env sequences is able to rescue the defective retrovirus vector from macrophages, allowing gene transfer into muscle precursor cells. After fusion, these cells gave rise to genetically modified myotubes in vitro.

Abstract
Objective To investigate whether differences in admixture in African American (AFA) and Hispanic American (HA) adult women are associated with adiposity and adipose distribution. Design The proportion of European, sub– Saharan African and Amerindian admixture was estimated for AFA and HA women in the Women's Heath Initiative using 92 ancestry informative markers. Analyses assessed the relationship between admixture and adiposity indices. Subjects 11712 AFA and 5088 HA self– identified post– menopausal women. Results There was a significant positive association between body mass index (BMI) and African admixture when BMI was considered as a continuous variable, and age, education, physical activity, parity, family income and smoking were included covariates (p < 10− 4). A dichotomous model (upper and lower BMI quartiles) showed that African admixture was associated with a high odds ratio [OR = 3.27 (for 100% admixture compared to 0% admixture), 95% confidence interval (CI) 2.08 – 5.15]. For HA there was no association between BMI and admixture. In contrast, when waist to hip ratio (WHR) was used as a measure of adipose distribution, there was no significant association between WHR and admixture in AFA but there was a strong association in HA (p<10− 4; OR Amerindian admixture = 5.93, CI = 3.52 – 9.97). Conclusion These studies show that 1) African admixture is associated with BMI in AFA women; 2) Amerindian admixture is associated with WHR but not BMI in HA women; and 3) it may be important to consider different measurements of adiposity and adipose distribution in different ethnic population groups.

Abstract
BACKGROUND Vitamins A and E are recognisably important in the initial stages of life, and the newborn depends on nutritional adequacy of breast milk to meet their needs. These vitamins share routes of transport to the tissues and antagonistic effects have been observed in animals after supplementation with vitamin A. The present study aimed to determine the effect of maternal supplementation with a megadose of retinyl palmitate in the immediate post-partum on α-tocopherol concentration in the colostrum. METHODS Healthy parturient women at a Brazilian public maternity were recruited for the study and divided into two groups: control (n = 37) and supplemented (n = 36). Blood and colostrum samples were collected up to 16 h post-partum. The supplemented group was administered with a retinyl palmitate capsule and, 24 h after the first collection, the second colostrum sample was obtained in the two groups for analysis of α-tocopherol. The cut-off points for deficiency are <1.05 μmol L(-1) for retinol and <11.6 μmol L(-1) for α-tocopherol. RESULTS The mean (SD) serum concentration of 1.77 (0.50) μmol L(-1) for retinol and 30.81 (6.46) μmol L(-1) for α-tocopherol indicates an adequate biochemical status. The supplemented group showed an increase of α-tocopherol in the colostrum 24 h after supplementation (P = 0.04), and this finding was not observed in the control group. CONCLUSIONS Supplementation with a 200,000 IU megadose of vitamin A did not negatively affect α-tocopherol levels in colostrum.

Abstract
Spontaneous rupture of an unscarred uterus in reproductive-age women is exceedingly rare, especially in the context of dysfunctional bleeding and a patent cervical canal. A 25-year-old nulligravida female, who reported recent onset of metromenorrhagia and anemia, was initially admitted for surgical management of unexplained hematometra requiring dilation and curettage. The patient remained with intermittent vaginal bleeding for the following six months on continuous progestin therapy. She then re-presented with enlarged hematometra and uterine rupture, which was surgically repaired. Despite exhaustive conservative treatment to preserve fertility, hysterectomy was eventually required due to recurrent uterine rupture. Idiopathic recurrent hematometra can result from the rare combination of uncontrolled dysfunctional bleeding and absence of outflow obstruction.

Abstract
For the resistive pressure-gradient-driven turbulence model, the transition from laminar regime to fully developed turbulence is not simple and goes through several phases. For low values of the plasma parameter beta, a single quasicoherent structure forms. As beta increases, several of these structures may emerge and in turn take the dominant role. Finally, at high beta, fully developed turbulence with a broad spectrum is established. A suitable characterization of this transition can be given in terms of topological properties of the flow. Here, we analyze these properties that provide an understanding of the turbulence-induced transport and give a measure of the breaking of the homogeneity of the turbulence. To this end, an approach is developed that allows discriminating between topological properties of plasma turbulence flows that are relevant to the transport dynamics and the ones that are not. This is done using computational homology tools and leads to a faster convergence of numerical results for a fixed level of resolution than previously presented in Phys. Rev. E 78, 066402 (2008).
