Rates of major depressive disorder (MDD) have steadily increased over the past 50 years. Many factors have been implicated in the etiology of depressive disorders and environmental influences are being increasingly recognized. The increase in depression rates has coincided with increased artificial nighttime lighting. Exposure to light at night (LAN) has been associated with increased depressive-like behavior in rodents and decreased mood in humans. However, relatively little is known on the multigenerational effects of dLAN on affect...

Relatively little attention has been given paternal effects on next generation. Given that Bisphenol A (BPA), a ubiquitous compound in maternal diet, may disrupt brain development and behavior, we hypothesized that paternal BPA diet (PBD) could affect offspring development. Prefrontal cortex (PFC), a vital brain region, is involved in emotion and social behavior. To test whether PBD could alter developing PFC, we carried out a proteomics approach for PFC in male juvenile offspring that responded to PBD (50 mg BPA/kg diet)...

BACKGROUND AND OBJECTIVES: The emerging association of assisted reproductive techniques (ART) with imprinting disorders represents a major issue in the scientific debate on infertility treatment and human procreation. We studied the prevalence of Beckwith-Wiedemann syndrome (BWS) in children conceived through ART to define the specific associated relative risk. METHODS: Patients with BWS born in Piemonte, Italy, were identified and matched with the general demographic data and corresponding regional ART registry...

Evidence has been accumulating for the impact of normal variation in caregiving quality on brain morphology in children, but the question remains whether differences in brain volume related to early caregiving translate to behavioral implications. In this longitudinal population-based study (N = 162), moderated mediation was tested for the relation between parental sensitivity and child prosocial behavior via brain volume, in boys and girls. Both maternal and paternal sensitivity were repeatedly observed between 1 and 4 years of age...

BACKGROUND AND OBJECTIVES: Exclusive breastfeeding provides many benefits to both infants and mothers. Despite the introduction of laws aimed at protecting the practice of exclusive breastfeeding, the coverage of exclusive breastfeeding remains low, particularly for working mothers. METHODS AND STUDY DESIGN: This crosssectional study recruited working mothers employed in medium and large companies in Bantul District, Daerah Istimewa Yogyakarta, Indonesia. The study participants were 158 working mothers whose children were aged 6- 12 months, and they were selected using the probability proportional to size technique...

Balanced reciprocal translocations are relatively common human genetic abnormalities that involve the exchange of the terminal segments between different chromosomes and have an approximately 5-80% chance of generating an embryo with chromosomal abnormalities. Non-invasive prenatal testing (NIPT) has been increasingly used in clinical practice to detect fetal trisomies 21, 18 and 13 with a sensitivity and specificity of up to 99%. In this report, we describe a duplication on chromosome 10 and a deletion on chromosome 5 that were first detected on NIPT...

Prior knowledge on heading date enables the selection of parents of synthetic cultivars that are well matched with respect to time of heading, which is essential to ensure plants put together will cross pollinate. Heading date of individual plants can be determined via direct phenotyping, which has a time and labour cost. It can also be inferred from family means, although the spread in days to heading within families demands roguing in first generation synthetics. Another option is to predict heading date from molecular markers...

BACKGROUND: Paternal zygosity testing is used for determining homo- or hemizygosity of RHD in pregnancies that are at a risk of hemolytic disease of the fetus and newborn. At present, this is achieved by using real-time PCR or the Rhesus box PCR, which can be difficult to interpret and unreliable, particularly for black African populations. METHODS: DNA samples extracted from 58 blood donors were analyzed using 2 multiplex reactions for RHD-specific targets against a reference (AGO1)(2) to determine gene dosage by digital PCR...

Polyandry is a common phenomenon and challenges the traditional view of stronger sexual selection in males than in females. In simultaneous hermaphrodites, the physical proximity of both sex functions was long thought to preclude the operation of sexual selection. Laboratory studies suggest that multiple mating and polyandry in hermaphrodites may actually be common, but data from natural populations are sparse. We therefore estimated the rate of multiple paternity and its seasonal variability in the annual, sperm-storing, simultaneously hermaphroditic freshwater snail Radix balthica for the entire duration of the reproductive lifespan...

Published by the Combined DNA Index System (CODIS) program of the Federal Bureau of Investigation (FBI) in 1997, the 13 core short tandem repeat (STR) loci are widely adopted as genetic markers in forensic applications, e.g., identity testing and paternity testing. However, these loci may be biased and suffer from reduced sensitivities towards specific population groups. In addition, the rapid growth of entries in forensic databases raises the chance of random hits, which can cause false recognitions of criminal suspects...

Gold nanoparticles, 5-20 nm in diameter, were generated with a pulsed Nd:YAG laser at 1010 W/cm2 at solution concentrations ranging between 1-100 mg/ml. Nanoparticles were characterized using optical absorbance, X-ray fluorescence, SEM, and TEM. Biocompatible nanoparticle solutions were injected by intravenously into the tail veins of mice followed by X-ray imaging using 20-45 keV photons to evaluate the uptake and the clearance by different organs of the nanoparticles. The incremental X-ray contrast imaging using gold nanoparticles was investigated and measured...

A robust, disease-relevant phenotype is paramount to the validity of genetic mouse models, which are an important tool in understanding complex diseases. Recent evidence from genome-wide association studies suggests the genetic contribution of parents to offspring is not equivalent. Despite this, few studies to date have examined the potential impact of parent genotype (i.e. origin of mutation) on the offspring of disease-relevant genetic mouse models. To elucidate the potential impact of the sex of the mutant parent on offspring phenotype, we characterized male and female offspring of an established schizophrenia mouse model, which had been generated using two different breeding schemes, in a range of disease-relevant behaviours...

Heretofore, transgenesis in the parasitic nematode genus Strongyloides has relied on microinjecting transgene constructs into gonadal syncytia of free-living females. We now report transgenesis in Strongyloides stercoralis by microinjecting constructs into the syncytial testes of free-living males. Crosses of individual males microinjected with a construct encoding GFP with cohorts of 12 non-injected females produced a mean of 7.28±2.09 transgenic progeny. Progeny of males and females microinjected with distinct reporter constructs comprised 2...

The steroid testosterone (T) and neuropeptide oxytocin (OT) have each been implicated in the development of parental care in humans and animals, yet very little research addressed the interaction between these hormones at the transition to parenthood in mothers and fathers. One hundred and sixty mothers and fathers (80 couples) were visited 1 and 6months after the birth of their first child, plasma OT and T were assayed at each time-point, and interactions between each parent and the infant were observed and micro-coded for two key parental behaviors; affectionate touch and parent-infant synchrony...
