Transgenic pigs have become an attractive research model in the field of translational research, regenerative medicine, and stem cell therapy due to their anatomic, genetic and physiological similarities with humans. The development of fluorescent proteins as molecular tags has allowed investigators to track cell migration and engraftment levels after transplantation. Here we describe the development of two transgenic pig models via SCNT expressing a fusion protein composed of eGFP and porcine Histone 2B (pH2B)...

BACKGROUND: Research about termination for fetal abnormality (TFA) suggests that it is a traumatic event with potential negative psychological consequences. However, evidence also indicates that following traumatic events individuals may experience growth. Although TFA's negative psychological outcomes are well documented, little is known of the potential for growth following this event. Therefore, the study's objectives were to measure posttraumatic growth (PTG) post-TFA, examine the relationship between PTG, perinatal grief and coping, and determine the predictors of PTG...

INTRODUCTION: The recommended daily intake of iodide, is 150 μg for adolescents and adults, 175 μg for pregnancy and 200 μg for lactation. Thyroid gland is an effective collector of iodine. EVIDENCE ACQUISITION: The active iodine uptake along the basolateral membrane of thyroid cell is followed by its transport to the apical edge of the cell and then to the follicle lumen. TSH acts through cAMP and stimulates NIS gene expression and protein synthesis. The major proportion of iodine in the thyroid gland is bound to Thyroglobulin...

: As human cytomegalovirus (HCMV) is the most common infectious cause of fetal anomalies during pregnancy, developing a vaccine that prevents HCMV infection is considered a global health priority. Although HCMV immune correlates of protection are only poorly defined, neutralizing antibodies (NAb) targeting the envelope pentamer complex (PC) composed of subunits gH, gL, UL128, UL130, and UL131A are thought to contribute in preventing HCMV infection. Here, we describe a continuous target sequence within UL128 that is recognized by a previously isolated potent PC-specific NAb, termed 13B5...

INTRODUCTION: Pelvic floor disorders (PFDs), including pelvic organ prolapse (POP), stress and urgency urinary incontinence, and faecal incontinence, are common and arise from loss of pelvic support. Although severe disease often does not occur until women become older, pregnancy and childbirth are major risk factors for PFDs, especially POP. We understand little about modifiable factors that impact pelvic floor function recovery after vaginal birth. This National Institutes of Health (NIH)-funded Program Project, 'Bridging physical and cultural determinants of postpartum pelvic floor support and symptoms following vaginal delivery', uses mixed-methods research to study the influences of intra-abdominal pressure, physical activity, body habitus and muscle fitness on pelvic floor support and symptoms as well as the cultural context in which women experience those changes...

A major goal of evolutionary biology is to identify the genome-level targets of natural and sexual selection. With the advent of next-generation sequencing, whole-genome selection components analysis provides a promising avenue in the search for loci affected by selection in nature. Here, we implement a genome-wide selection components analysis in the sex-role-reversed Gulf pipefish, Syngnathus scovelli. Our approach involves a double-digest restriction-site associated DNA sequencing (ddRAD-seq) technique, applied to adult females, non-pregnant males, pregnant males and their offspring...

Absence epileptic activity was analyzed during pregnancy, the postpartum period and after weaning to establish alterations of seizures throughout the reproductive cycle. Wistar Albino Glaxo Rijswijk (WAG/Rij) rats were used in the study as a model of absence epilepsy and because their seizures do not interfere with rearing offspring. The number of spike-wave discharges (SWDs) was gradually elevated from the 19(th) pregnancy day to delivery. Meanwhile, the characteristics of individual SWDs did not change suggesting that SWD generation remained the same...

Adiponectin is one of the adipokines in the collagen superfamily. It is secreted primarily by white adipocytes and influences reproductive processes including ovarian and uterine functions. Adiponectin regulates energy homeostasis, insulin sensitivity and is anti-inflammatory in various tissues. Its receptors (ADIPOR1 and ADIPOR2) are widely expressed in mammalian tissues, including porcine conceptuses and endometrial during the estrous cycle and peri-implantation period of pregnancy. However, regulatory effects of adiponectin on endometrial epithelial cells are unknown...
