OBJECTIVES: Neurologic and functional morbidity occurs in ~30% of PICU survivors, and young children may be at particular risk. Bronchiolitis is a common indication for PICU admission among children less than 2 years old. Two single-center studies suggest that greater than 10-25% of critical bronchiolitis survivors have neurologic and functional morbidity but those estimates are 20 years old. We aimed to estimate the burden of neurologic and functional morbidity among more recent bronchiolitis patients using two large, multicenter databases...

MicroRNAs (miRNAs) have been known to affect various biological processes by repressing expression of specific genes. Here we describe an essential function of the miR-34/449 family during differentiation of epithelial cells. We found that miR-34/449 suppresses the cell-cycle machinery in vivo and promotes cell-cycle exit, thereby allowing epithelial cell differentiation. Constitutive ablation of all six members of this miRNA family causes derepression of multiple cell cycle-promoting proteins, thereby preventing epithelial cells from exiting the cell cycle and entering a quiescent state...

OBJECTIVES: Using a strategy of placing a surgical drain after kidney transplantation, the duration of a lymphatic fluid leakage and prevalence of a symptomatic lymphocele were retrospectively analyzed. The risk factors for persistent lymphatic fluid leakage or asymptomatic lymphocele were evaluated using multivariate analysis to estimate the origin of the lymphatic fluid leakage. MATERIALS AND METHODS: Patients with persistent lymphatic fluid leakage and symptomatic lymphocele were defined as those with lymphatic fluid drainage >50 mL for more than 15 days and those who required a percutaneous drainage of the lymphocele, respectively...

Thienoisoindigo-based semiconducting polymer with a strong near-infrared absorbance is synthesized and its water-dispersed nanoparticles (TSPNs) are investigated as a contrast agent for photoacoustic (PA) imaging in the second near-infrared (NIR-II) window (1000-1350 nm). The TSPNs generate a strong PA signal in the NIR-II optical window, where background signals from endogenous contrast agents, including blood and lipid, are at the local minima. By embedding a TSPN-containing tube in chicken-breast tissue, an imaging depth of more than 5 cm at 1064 nm excitation is achieved with a contrast-agent concentration as low as 40 µg mL(-1) ...

PROBLEM: The role of extracellular signal-regulated kinase (ERK)1/2-mediated angiogenesis during endometriotic nidation is unknown. We posit that ERK1/2-induced angioblast differentiation and proliferation promotes ectopic endometrial angiogenesis. METHODS OF STUDY: Human eutopic and ectopic endometria were immunostained for total- (T-) or phosphorylated- (P-) ERK1/2 or double-immunostained for P-ERK1/2-CD34 and PCNA-CD34. Estradiol (E2 ), cytokines, normal peritoneal fluid (NPF) or endometriotic peritoneal fluid (EPF) ±PD98059, an ERK1/2 inhibitor, treaded primary human endometrial endothelial cells (HEECs) were evaluated by T-/P-ERK1/2 immunoblotting, MTT viability and tube formation assays...

BACKGROUND: Meconium ileus is a common cause of neonatal intestinal obstruction. Various surgical procedures are in practice for uncomplicated meconium ileus. Bishop Koop ileostomy allows distal passage of gut content and uses the distal absorptive area. T tube ileostomy avoids the need for gut resection and formal closure of stoma. The aim of this prospective interventional study was to compare the outcome of T-tube ileostomy and Bishop Koop ileostomy for the treatment of uncomplicated meconium ileus...

BACKGROUND: Early childhood caries (ECC) is characterized by the presence of one or more decayed, missing (due to caries), or filled teeth surfaces in any primary tooth, in a child below 6 years of age. Although ECC is primarily associated with high levels of maternal Streptococcus mutans, there has been an increased interest in finding the relationship between oral fungal flora and dental caries. OBJECTIVE: The aim of the study is to identify and characterize the Candida species and to compare the candidal isolates in children with ECC and without ECC...

Dermatomyositis (DM) is a rare autoimmune condition which predominantly affects females in the fifth and sixth decades of life. DM presents acutely or progressively as painless proximal skeletal muscle weakness and can be associated with a heliotropic rash around the eyes, and Gottron's papules on extensor surfaces of the hands. While the pathophysiology of DM is still unclear, abnormal T- and B-cell immune activity has been reported. DM has been associated with malignancy and has been shown to appear before, concurrently with, or after diagnosis of cancer...

We report the first direct kinetic study of the gas-phase reaction NaOH + H → Na + H2O, which is central to the chemistry of sodium in the upper atmosphere and in flames. The reaction was studied in a fast flow tube where NaOH was observed by multi-photon ionization and time-of-flight mass spectrometry, yielding k(NaOH + H, 230 - 298 K) = (3.8 ± 0.8)  10-11 cm3 molecule -1 s-1 (at 2σ confidence level), showing no significant temperature dependence over the indicated temperature range and essentially in agreement with previous estimates of the rate constant in hydrogen-rich flames...

Angiosperm diversity has been shaped by mating system evolution, with the most common transition from outcrossing to self-fertilizing. To investigate the genetic basis of this transition, we performed crosses between two species endemic to the Canary Islands, the self-compatible (SC) species Tolpis coronopifolia and its self-incompatible (SI) relative Tolpis santosii. We scored self-compatibility as self-seed set of recombinant plants within two F2 populations. To map and genetically characterize the breakdown of SI, we built a draft genome sequence of T...
