Palatal rugae patterns are anatomic structures considered unique to each person. Monozygotic twins present similarities, however, Rugoscopy in particular, may contribute to their individualization for forensic purposes. The aims of this study were: to study the palatal rugae classifications of Briñón; to propose improvements to facilitate use of this method, if pertinent; and to characterize palatal rugae in a sample of Brazilian monozygotic twins and singletons. Precise reproducibility of the two methods of Briñón, from 1982 and 2011, was prevented by poor intra-examiner agreement (70% and 13% respectively)...

The twin-arginine translocation (Tat) system, which is used for folded protein secretion, is rare in lactic acid bacteria (LAB). Previously, a Tat system composed of TatAS and TatCS subunits (the subscript S denotes a Streptococcus thermophilus origin) was identified in S. thermophilus CGMCC 7.179. In the present study, the tatA S and tatC S genes were cloned and functionally analyzed in Escherichia coli DE3 tat-deficient mutants. The E. coli tatABCDE-deficient mutant complemented with tatC S A S exhibited shortened cellular chains, but its ability to grow in the presence of sodium dodecyl sulfate (SDS) was not restored, suggesting that the S...

Nuclear receptor subfamily 5, group A, member 1 (NR5A1) is a nuclear receptor involved in gonadal and adrenal development. We identified a novel C-terminally truncating NR5A1 mutation, p.Leu423Trpfs*7, in dizygotic twins with 46,XY disorders of sex development. Our results highlight the functional importance of C-terminal region of NR5A1 and indicate that NR5A1 mutations can be associated with intrafamilial phenotypic variations, progressive testicular dysfunction, hypogonadotropic hypogonadism, and borderline adrenal dysfunction...

Rising cancer incidence and mortality in India emphasize the need to address the increasing burden of this disease and the stark inequities in access to radiotherapy and other essential medical treatments. State-of-the-art technology is available within the private sector and a few hospitals in the public sector, but 75% of patients in the public sector in India do not have access to timely radiotherapy. This inequity in access to radiotherapy in the public sector is amplified in rural areas, where most of India׳s population lives...

The massive global shortfall in radiotherapy equipment and human resources in developing countries is an enormous challenge for international efforts in cancer control. This lack of access to treatment has been long-standing, but there is now a growing consensus about the urgent need to prioritize solutions to this problem and that a global strategy is required for them to be successful. An essential element of making radiotherapy universally accessible is a coordinated approach to clinical training and practice...

The aim of this study was to review the indications for caesarean delivery of second twins after vaginal delivery of a first twin (combined delivery) and the associated foetal outcomes of the second twin. Possible factors that could be employed to predict combined delivery were explored. This was a retrospective review of all twin pregnancies delivered in a tertiary maternity unit between 2000 and 2013. All twins (> =24 week gestation) with vaginal delivery of the first twin were reviewed. Of a total of 1039 pairs of twins, 441 pairs had vaginal delivery of the first twin, of which 47 (10...

In this paper, we propose a new time-shared twin memristor crossbar for pattern-recognition applications. By sharing two memristor arrays at different time, the number of memristor arrays can be reduced by half, saving the crossbar area by half, too. To implement the time-shared twin memristor crossbar, we also propose CMOS time-shared subtractor circuit, in this paper. The operation of the time-shared twin memristor crossbar is verified using 3 × 3 memristor array which is made of aluminum film and carbon fiber...

The aim of this study was to investigate whether neighborhood walkability moderates the association between low back pain (LBP) and physical activity (PA), using a co-twin design to control for genetics and shared environmental factors. A cross-sectional analysis was performed on 10,228 twins from the Washington State Twin Registry with available data on LBP from recruitment surveys between 2009 and 2013. LBP within the past 3months was our exposure variable. Our outcome variables were sufficient moderate or vigorous-intensity PA (MVPA, defined as at least 75min of vigorous-intensity PA, or 150min of moderate-intensity PA per week), and walking (≥150min per week)...

Infertility, defined as the inability to conceive within one year of unprotected intercourse, affects an estimated 80 million individuals worldwide, or 10-15 percent of couples of reproductive age. Assisted reproductive technology (ART) includes all infertility treatments to achieve conception; in vitro fertilization (IVF) is the process by which an oocyte is fertilized by semen outside the body; non-IVF ART treatments include ovulation induction, artificial insemination, and intrauterine insemination. Use of ART has risen steadily in the United States during the past two decades due to several reasons, including childbearing at older maternal ages and increasing insurance coverage...

The study of monozygotic twins discordant for attention deficit hyperactivity disorder can elucidate mechanisms that contribute to the disorder, which affects ~7% of children. First, using in vivo neuroanatomic imaging on 14 pairs of monozygotic twins (mean age 9.7, s.d. 1.9 years), we found that discordance for the disorder is mirrored by differing dimensions of deep brain structures (the striatum and cerebellum), but not the cerebral cortex. Next, using whole-blood DNA from the same twins, we found a significant enrichment of epigenetic differences in genes expressed in these 'discordant' brain structures...

An improvement in quality of life and survival occurred among thalassemia major (TM) patients: pregnancy in such patients has become a reality. Safe pregnancy and delivery require efforts to ensure the best outcomes. Between 2007 and 2016, 30 TM patients had 37 pregnancies. We analyzed the hematological parameters before, during, and after pregnancies and in 19 patients a cardiovascular magnetic resonance (CMR) T2* was performed. The mean age at first pregnancy was 30 ± 4 years; the current mean age is 35 ± 5 years...

BACKGROUND: The Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD) has proven effective in increasing parental sensitivity. However, the mechanisms involved are largely unknown. In a randomized controlled trial we examine parental neurocognitive factors that may mediate the intervention effects on parenting behavior. Our aims are to (1) examine whether the intervention influences parents' neural processing of children's emotional expressions and the neural precursors of response inhibition and to (2) test whether neural changes mediate intervention effects on parenting behavior...
