Chromium exposure from increasing industrial releases has become a threat for pregnant women due to the potential health effects on vulnerable embryos. Previous studies have suggested that maternal chromium exposure is associated with adverse birth outcomes, but no epidemiological research has been conducted to examine the relationship between chromium exposure and premature rupture of membranes (PROM). This study aimed at investigating the association of maternal urinary chromium exposure levels with PROM and was performed with 5408 pregnant women recruited from 2012 to 2014 in the city of Wuhan, China...

Mutagenesis in model organisms following exposure to chemicals is used as an indicator of genotoxicity. Mutagenesis assays are also used to study mechanisms of DNA homeostasis. This chapter focuses on detection of mutagenesis in prokaryotes, which boils down to two approaches: reporter inactivation (forward mutation assay) and reversion of an inactivating mutation (reversion mutation assay). Both methods are labor intensive, involving visual screening, quantification of colonies on solid media, or determining a Poisson distribution in liquid culture...

The pudendal nerve entrapment is an entity understudied by diagnosis imaging. Various causes are recognized in relation to difficult labors, rectal, perineal, urological and gynecological surgery, pelvic trauma fracture, bones tumors and compression by tumors or pelvic pseudotumors. Pudendal neuropathy should be clinically suspected, and confirmed by different methods such as electrofisiological testing: evoked potentials, terminal motor latency test and electromyogram, neuronal block and magnetic resonance imaging...

Selection for probiotic candidates by in vivo experimental trials is time and labor consuming; more informed strategy is needed to select successful probiotic candidates. The aim of the study was to elucidate the microbial taxa transmitted from maize seeds to seedlings during the germination process of maize and their probiotic effects. The bacterial and fungal taxa in kernel germs and sprouts were analyzed by Illumina-based sequencing. The sprouts contained more diverse fungi than those in germs. The bacterial species (OTUs) declined with the germination from germs to the sprouts...

Rong Hai, James J Heckman
This paper investigates the determinants of inequality in human capital with an emphasis on the role of the credit constraints. We develop and estimate a model in which individuals face uninsured human capital risks and invest in education, acquire work experience, accumulate assets and smooth consumption. Agents can borrow from the private lending market and from government student loan programs. The private market credit limit is explicitly derived by extending the natural borrowing limit of Aiyagari (1994) to incorporate endogenous labor supply, human capital accumulation, psychic costs of working, and age...

BACKGROUND: Staff turnover is a major issue for health care systems. In a time of labor shortage, it is critical to understand the motivational factors that underlie turnover intention in newly licensed nurses. PURPOSE: To examine whether different forms of motivation (the reasons for which nurses engage in their work) predict intention to quit the occupation and organization through distinct forms (affective and continuance) and targets (occupation and organization) of commitment...

BACKGROUND: In the United States, hyperemesis gravidarum is the most common cause of hospitalization during the first half of pregnancy and is second only to preterm labor for hospitalizations in pregnancy overall. In approximately 0.3-3% of pregnancies, hyperemesis gravidarum is prevalent and this percentage varies on account of different diagnostic criteria and ethnic variation in study populations. Despite extensive research in this field, the mechanism of the disease is largely unknown...

Professional guidelines define the second stage of labor as 'prolonged' at three hours for primiparous women with an epidural and two hours without, and at two hours for parous women with an epidural and one hour without(1). NICE guidelines from the UK define second stage length similarly, but take into consideration passive time at full cervical dilation and the time in active pushing(2).

With cotton fiber growth or maturation, cellulose content in cotton fibers markedly increases. Traditional chemical methods have been developed to determine cellulose content, but it is time-consuming and labor-intensive, mostly owing to the slow hydrolysis process of fiber cellulose components. As one approach, the attenuated total reflection Fourier transform infrared (ATR FT-IR) spectroscopy technique has also been utilized to monitor cotton cellulose formation, by implementing various spectral interpretation strategies of both multivariate principal component analysis (PCA) and 1-, 2- or 3-band/-variable intensity or intensity ratios...

In this paper, we explore whether individuals who strive to self-verify flourish or flounder on the job market. Using placement data from 2 very different field samples, we found that individuals rated by the organization as being in the top 10% of candidates were significantly more likely to receive a job offer if they have a stronger drive to self-verify. A third study, using a quasi-experimental design, explored the mechanism behind this effect and tested whether individuals who are high and low on this disposition communicate differently in a structured mock job interview...

Transcutaneous electrical nerve stimulation (TENS), as a non-pharmacological and non-invasive analgesic therapy with low-cost, has been widely used to relieve pain in various clinical applications, by delivering current pulses to the skin area to activate the peripheral nerve fibers. Nevertheless, analgesia induced by TENS varied in the clinical practice, which could be caused by the fact that TENS with different stimulus parameters has different biological mechanisms in relieving pain. Therefore, to advance our understanding of TENS in various basic and clinical studies, we discussed (1) neurophysiological and biochemical mechanisms of TENS-induced analgesia; (2) relevant factors that may influence analgesic effects of TENS from the perspectives of stimulus parameters, including stimulated position, pulse parameters (current intensity, frequency, and pulse width), stimulus duration and used times in each day; and (3) applications of TENS in relieving clinical pain, including post-operative pain, chronic low back pain and labor pain...
