BACKGROUND AND OBJECTIVE: Retinopathy of prematurity (ROP) is a leading cause of blindness in premature and low birth weight infants. Here, the authors examine the incidence of ROP in the United States and evaluate risk factors associated with ROP development. PATIENTS AND METHODS: The National Healthcare Cost and Utilization Project Kids' Inpatient Database was queried for all newborns with and without ROP. Adjusted odds ratios were constructed for predictors of ROP using multivariate logistic regression modeling...

During development, neural stem cells (NSCs) undergo transitions from neuroepithelial cells to radial glial cells (RGCs), and later, a subpopulation of slowly dividing RGCs gives rise to the quiescent adult NSCs that populate the ventricular-subventricular zone (V-SVZ). Here we show that VCAM1, a transmembrane protein previously found in quiescent adult NSCs, is expressed by a subpopulation of embryonic RGCs, in a temporal and region-specific manner. Loss of VCAM1 reduced the number of active embryonic RGCs by stimulating their premature neuronal differentiation while preventing quiescence in the slowly dividing RGCs...

BACKGROUND: Preterm birth is known to constitute the major risk factor for development of germinal matrix-intraventricular hemorrhage (GM-IVH). Head position may affect cerebral hemodynamics and thus may be involved indirectly in development of GM-IVH. Turning the head toward one side may functionally occlude jugular venous drainage on the ipsilateral side while increasing intracranial pressure and cerebral blood volume. Thus, it has been suggested that cerebral venous pressure is reduced and hydrostatic brain drainage improved if the patient is in supine midline position with the bed tilted 30°...

South Africans are at high risk for developing cardiovascular disease. Endothelin-1 is known for its vasoconstrictive properties and its ability to contribute to vascular structural changes. In this study we investigated the association of change in endothelin-1 levels and change in markers implicated in vascular remodelling after 3 years. Serum endothelin-1 levels and markers of vascular remodelling such as carotid intima-media thickness, carotid cross-sectional wall area (CSWA) and arterial compliance were measured...

Cellular senescence is an initial barrier to tumor development that prevents the proliferation of premalignant cells. However, some of the features of senescent cells seem to promote tumor progression via senescence-associated secretory phenotype (SASP). Here, we demonstrated that the protein level of forkhead box Q1 (FOXQ1), which highly overexpresses in several kinds of tumors, was significantly downregulated during both replicative and oncogene-induced senescence. Moreover, overexpression of FOXQ1 delayed senescence, whereas FOXQ1 silence led to premature senescence in human fibroblasts...

Cutis laxa is a disease of premature ageing. While the congenital type is characterized by mutations of genes involved in extracellular matrix turnover, acquired cutis laxa is a rare disease that can be induced by a variety of exogenous factors. We present a case of acquired type 2 cutis laxa of the neck due to excessive exposure to natural sunlight and a type 1 facial acquired cutis laxa, both significantly improved by minor invasive procedures. The etiology, prevention and treatment options are discussed.

Biological industries commonly rely on bioreactor systems for the large-scale production of cells. Cell aggregation, clumping, and spheroid morphology of certain suspension cells make their large-scale culture challenging. Growing stem cells as spheroids is indispensable to retain their stemness, but large spheroids (>500 µm diameter) suffer from poor oxygen and nutrient diffusion, ultimately resulting in premature cell death in the centers of the spheroids. Despite this, most large-scale bioprocesses do not have an efficient method for dissociating cells into single cells, but rely on costly enzymatic dissociation techniques...

We describe the case of a neonate who was prenatally diagnosed at a gestational age of 36 weeks with premature constriction of the ductus arteriosus. Blood from the thin ductus arteriosus flowed toward the pulmonary artery. Severe tricuspid regurgitation was also observed. We subsequently confirmed rupture of the tricuspid papillary muscle after birth. Cardiotonic drugs and nitric oxide were administered immediately at birth for pulmonary hypertension, and this therapy was continued until the seventh postnatal day...

We report an isolated sulfite oxidase deficiency in the first child boy of a non-consanguineous Caucasian family. He's a compound heterozygote for the sulfite oxidase gene, presenting low cystine, undetectable homocysteine and normal uric acid blood concentrations and undetectable sulfite oxidase activity in his cultured fibroblasts. Both mutations are not reported yet. The clinical presentation was typical and severe, with generalized status epilepticus and premature death.

Natural infection of baboons with simian T lymphotropic virus (STLV) is a potentially useful model system for study of vaccination against the human virus HTLV. Here we expand the number of available full-length STLV-1 baboon sequences from one to three and relate T cell responses that recognize the immunodominant Tax protein to the tax sequences present in two individual baboons. Continuously growing T cell lines were established from two baboons, 12141 and 12752. Next-generation sequencing (NGS) of complete STLV genome sequences from these lines revealed them to be closely related but distinct from each other and from the STLV-1 baboon sequence in the NCBI sequence database...

BACKGROUND: The ciliopathies represent an umbrella group of >50 clinical entities that share both clinical features and molecular etiology underscored by structural and functional defects of the primary cilium. Despite the advances in gene discovery, this group of entities continues to pose a diagnostic challenge, in part due to significant genetic and phenotypic heterogeneity and variability. We consulted a pediatric case from asymptomatic, non-consanguineous parents who presented as a suspected ciliopathy due to a constellation of retinal, renal, and skeletal findings...

Successive division events in the spherically shaped bacterium Staphylococcus aureus are oriented in three alternating perpendicular planes. The mechanisms that underlie this relatively unique pattern of division and coordinate it with chromosome segregation remain largely unknown. Thus far, the only known spatial regulator of division in this organism is the nucleoid occlusion protein Noc that inhibits assembly of the cytokinetic ring over the chromosome. However, Noc is not essential in S. aureus, indicating that additional regulators are likely to exist...

The use of nuchal translucency (NT) in 1992 by Nicolaides et al was a major breakthrough in screening for chromosomal aneuploidies at the end of the first trimester. However, pathological conditions other than chromosomal aneuploidies are also associated with increased NT, which can also be detected in normal fetuses. This study sought to evaluate the causes of this ultrasound sign in a group of patients from Iasi, Romania.During the decade-long study period, there were 71 certified cases involving increased NT; the patients in these cases underwent diagnostic amniocentesis and karyotyping...
