A considerable research effort is focused on developing effective delivery systems for hydrophobic nutraceuticals. β-carotene, a pro-vitamin A carotenoid, requires encapsulation to improve its water dispersibility and chemical stability in foods. In this study, β-carotene was encapsulated in oil-in-water nanoemulsions fabricated using high-pressure dual-channel microfluidization. Two types of natural emulsifier, quillaja saponins (Q-Naturale) and whey protein isolate (WPI), were capable of producing nanoemulsions (d32=0...

Cesarean section rates have risen dramatically in China within the past 25 years, particularly driven by non-medical factors and maternal requests. One major reason women request cesareans is the fear of labor pain, in a country where a minority of women are given any form of pain relief during labor. Drawing upon ethnographic fieldwork and in-depth interviews with 26 postpartum women and 8 providers at a Shanghai district hospital in June and July of 2015, this article elucidates how perceptions of labor pain and the environment of pain relief constructs the cesarean on maternal request...

BACKGROUND: Labor induction has been associated with breastfeeding suppression, but reasons for why this association exists have not been well determined. METHODS: We examined the influence of elective labor induction by vaginal prostaglandin at gestational week 41(+3)days on affective, cognitive, and behavioural adaptations early in puerperium and on breastfeeding pattern at 1 and 3months. RESULTS: One hundred and eighty consecutive puerperae were assigned to two groups: mothers having received vaginal prostaglandin E2 gel (Prepidil®, dinoprostone) before labor (PGE group, n=90) and mothers having received no treatment (unmedicated group, n=90)...

The calculation of heart rate variability (HRV) is a popular tool used to investigate differences in cardiac autonomic control between population samples. When interpreting effect sizes to quantify the magnitude of group differences, researchers typically use Cohen's guidelines of small (0.2), medium (0.5), and large (0.8) effects. However, these guidelines were originally proposed as a fallback for when the effect size distribution (ESD) was unknown. Despite the availability of effect sizes from hundreds of HRV studies, researchers still largely rely on Cohen's guidelines to interpret effect sizes and to perform power analyses to calculate required sample sizes for future research...

Bone mineral density (BMD) has been suggested to be associated with atherosclerosis. In the present study, we evaluated the association between lumbar BMD and the segments of carotid intima-media thickness (CIMT), a surrogate marker of subclinical atherosclerosis, in Korean adults, with consideration of sex and menopause status. Among 1,679 Korean adults who enrolled in a Healthy Twin Study, 723 men, 690 premenopausal women, and 266 postmenopausal women measured the CIMT at the common carotid artery intima-media thickness (CCA-IMT), carotid bifurcation intima-media thickness (BIF-IMT), internal carotid artery intima-media thickness (ICA-IMT) using B-mode ultrasound and lumbar BMD using dual-energy X-ray absorptiometry...

Oxidative stress induced by hemorrhagic shock (HS) initiates a systemic inflammatory response, which leads to subsequent kidney injury. This study assessed the efficacy of c-type natriuretic peptide (CNP) in attenuating kidney injury in a rat model of hemorrhagic shock and resuscitation (HS/R). Sodium pentobarbital-anesthetized adult male Wistar rats underwent HS induced by the withdrawal of blood to a mean arterial pressure of 30-35 mmHg for 50 min. Then, the animals received CNP (25 μg/kg) or vehicle (saline) intravenously, followed byresuscitation with 1...

PURPOSE: Alpha-actinin-3, encoded by the ACTN3 gene, is an actin-binding protein with an important role in myofibril contraction and muscle force output. In humans, there is a relatively common deficiency of the α-actinin-3 due to homozygosity in a polymorphism of the ACTN3 gene (R577X, rs1815739), that has been related to decreased resistance to strain during voluntary muscle contractions. The purpose of this study was to investigate the influence of the ACTN3 genotype on the level of exercise-induced muscle damage attained by 23 experienced triathletes during an official half-ironman competition...
