BACKGROUND: Premature birth occurs when nephrogenesis is incomplete and has been linked to increased renal pathologies in the adult. Metabolic factors complicating preterm birth may have additional consequences for kidney development. Here, we evaluated the effects of prematurity and hyperglycemia on nephrogenesis in premature baboons when compared to term animals. METHODS: Baboons were delivered prematurely (67% gestation; n=9) or at term (n=7) and survived 2-4 weeks...

Exposure to secondhand smoke from burning tobacco products causes premature death and disease, including coronary heart disease, stroke, and lung cancer among nonsmoking adults and sudden infant death syndrome, acute respiratory infections, middle ear disease, exacerbated asthma, respiratory symptoms, and decreased lung function in children (1,2). The U.S. Surgeon General has concluded that there is no risk-free level of exposure to secondhand smoke (1). Previous CDC reports on airport smoke-free policies found that most large-hub airports in the United States prohibit smoking (3); however, the extent of smoke-free policies at airports globally has not been assessed...

Suicide is the ultimate outcome of poor psychological well-being; however, there is a paucity of research examining the link between occupation and suicide, despite early academic interest and the known importance of work to our everyday lives. We propose that this body of research was abandoned prematurely, and we provide a reanalysis by integrating the Job Characteristics Model and the Conservation of Resources model with extant suicide research. Specifically, we hypothesize that work design characteristics (job autonomy, task variety, physical demands) and threats to personal resources (absence of viewing work-as-career, work-family conflict, family-work conflict, job dissatisfaction) are linked to suicide attempts via depression and suicidal ideation...

BACKGROUND: Pregnant women with heart disease (HD) have higher rates of adverse fetal outcomes. We describe placental pathologic characteristics and their association with fetal events. METHODS: In pregnant women, known HD were categorized into: (1) cardiomyopathy (CM) or (2) other HD (congenital, coronary, arrhythmia, or valvular). Outcomes were maternal major adverse cardiac events (MACE), fetal adverse clinical events (FACE), a composite of infant death, prematurity, underweight status, intracranial hemorrhage, and respiratory distress...

Premature infants tend to lose heat quickly. This loss can be aggravated when they have received an invasive procedure involving a venous puncture. This research uses crossover design by conducting 2 intervention tests to compare 2 different treatments on the same sample. This research involved 2 groups with 18 premature infants in each. The process of data analysis used a statistical independent t test. Interventions conducted in an open incubator showed a p value of .001 which statistically related to heat loss in premature infants...

A primary problem that occurs in premature infants is oxygenation disorders, thus requiring respiratory support, including continuous positive airway pressure (CPAP). The effectiveness of CPAP can be improved by adjusting the body's position, so the aim of this study was to examine the effect of the quarter prone position on the oxygenation status of preterm infants using CPAP. This study used a randomized controlled trial with a crossover design. A group of 15 preterm infants receiving CPAP was selected, and randomization of allocation was done to divide the respondents into the intervention group (quarter prone) or the control group (supine)...

Psychodynamically oriented multimodal therapy approaches are efficacious for outpatients with borderline personality disorder (BPD). Until now, no study has reported the effectiveness, response, and dropout in a psychodynamic oriented multimodal therapy program for inpatients (PDOMT). In this study, we compared the results of 269 individuals seeking a 3-month inpatient treatment with previous studies for BPD inpatients by examining 269 individuals. The Borderline Personality Index (CUT-20-R) was used as the main outcome measure...

Study Objectives: Fetal growth restriction (FGR) occurs in up to 10% of pregnancies and is associated with increased risk of prematurity and neurodevelopmental impairment. FGR also alters sleep state distribution in utero and maturation in infancy. Currently, limited data on the long-term associations of FGR and childhood sleep exist. Accordingly, we assessed the associations between preterm birth and FGR and sleep in children aged 5-12 years. Methods: 17 children born preterm and FGR, 15 children born preterm but appropriately grown (AGA) and 20 term AGA children (controls) were studied using overnight polysomnography...

Folates comprise the essential B9 vitamin that act as cofactors and cosubstrates in one-carbon metabolism for both biosynthesis and methylation of DNA and RNA. Folate deficiency (FD) has been shown to induce chromosomal instability (CIN), yet the underlying mechanisms are poorly understood. Here, we used human NCM460 colon mucosal cells as a model to investigate the effect of FD on spindle assembly checkpoint (SAC), a cell-cycle regulatory pathway preventing CIN during mitosis. Cells were maintained in medium containing 1...

The drug delivery by versatile types of self-assembled micelles for tumor treatment, which improved the diagnostic and therapeutic effectiveness, is advocated. However, despite the numerous advantages, applications of most micelle system have been retarded by low in vivo bio-stability which led to premature drug release and nonspecific tissue accumulation. To date, a range of chemistries has been introduced in intermolecular non-covalent/covalent crosslinking strategies for these dynamic nanostructures to produce robust functional nanoparticles with enhanced circulation stability and lower non-targeted organ toxicity...

Molecular engineering of manganese(II) diamine diketonate precursors is a key issue for their use in the vapor deposition of manganese oxide materials. Herein, two closely related β-diketonate diamine Mn(II) adducts with different fluorine contents in the diketonate ligands are examined. The target compounds were synthesized by a simple procedure and, for the first time, thoroughly characterized by a joint experimental-theoretical approach, to understand the influence of the ligand on their structures, electronic properties, thermal behavior, and reactivity...

Postpartum dysgalactia syndrome (PPDS) and locomotory disorders are common health problems in sows. Previous research suggests that they can cause substantial losses, reduce sow welfare, and result in premature removal of the sow from the herd. However, economic consequences of PPDS and locomotory disorders have not been investigated thoroughly. The goal of this study was to examine economic losses caused by PPDS and locomotory disorders and their impacts on sow longevity. A stochastic dynamic programming model, which maximizes return on sow space unit and assesses sow replacement under several scenarios, was developed...

Human milk contains active proteases that initiate hydrolysis of milk proteins within the mammary gland. Milk expressed at the beginning of feeding is known as foremilk and that at the end of feeding is known as hindmilk. As hindmilk contains higher fat, vitamins A and E, and higher calories than foremilk, feeding only hindmilk initially and reserving foremilk for later are practiced in some neonatal intensive care units. This study investigated the difference in peptide profiles, predicted milk protease activities, and bioactive peptides between foremilk and hindmilk...

Background: A dysregulation of the generation of vasoinhibin hormones by proteolytic cleavage of prolactin (PRL) has been brought into context with diabetic retinopathy, retinopathy of prematurity, preeclampsia, pregnancy-induced hypertension, and peripartum cardiomyopathy. Factors governing vasoinhibin generation are incompletely characterized, and the composition of vasoinhibin isoforms in human tissues or compartments, such as the circulation, is unknown. The aim of this study was to determine the possible contribution of PRL point mutations to the generation of vasoinhibins as well as to project their role in vasoinhibin-related diseases...

Background: Premature adrenarche (PA) has been linked to early thelarche and menarche, but longitudinal data on growth and pubertal development after PA are insufficient. Methods: Growth and pubertal development of mostly full-term and appropriate for gestational age-born 43 PA (36 girls) and 63 control children (52 girls) were analyzed prospectively. Children examined first at the mean age of 7.6 years were reexamined at the mean age of 12.0 years. Results: The PA girls but not the boys were taller and had higher body mass index (BMI) than the controls...

The auditory efferent system is a neural network that originates in the auditory cortex and projects to the cochlear receptor through olivocochlear (OC) neurons. Medial OC neurons make cholinergic synapses with outer hair cells (OHCs) through nicotinic receptors constituted by α9 and α10 subunits. One of the physiological functions of the α9 nicotinic receptor subunit (α9-nAChR) is the suppression of auditory distractors during selective attention to visual stimuli. In a recent study we demonstrated that the behavioral performance of alpha-9 nicotinic receptor knock-out (KO) mice is altered during selective attention to visual stimuli with auditory distractors since they made less correct responses and more omissions than wild type (WT) mice...

Medullary thymic epithelial cells (mTECs) ectopically express a diversity of peripheral tissue-restricted antigens (PTAs) and provide unique cues for the expansion, maturation and selection of a repertoire of functionally diverse T lymphocytes. Genetic deletion of all mature microRNAs in thymic epithelial cells (TECs) results in premature thymic involution, progressive disorganisation of the thymic epithelium, and alteration in thymic T cell lineage commitment, consequently eliciting autoimmune disorders. In the present study, we identified that microRNA-449a (miR-449a), a member of miR-449 cluster, regulated mTEC differentiation...

Biotronik devices used for cardiac resynchronization therapy (CRT) combined with defibrillation function (CRT-D) are capable of left ventricular (LV) sensing. Under certain circumstances, LV sensing may cause loss of CRT. The third generation of the Biotronik i-family CRT-Ds enables the recording of event-triggered tracings of the electrogram particularly those involving "CRT pacing interrupt" episodes. We report three cases of a sudden "CRT pacing interrupt" initiated by an atrial premature complex. This was caused by realignment of the LV timing cycles induced by the APCs whereupon LV pacing was inhibited and a self-perpetuating desynchronization process was initiated...
