uretero pelvic junction (upj) obstruction is a common cause of hydronephrosis in infants. the frequent use of fetal ultrasound is allowing early (prenatal) diagnosis of numerous uropathies previously delayed until the child either became symptomatic or had a palpable mass. newborn with severe obstruction often has marked improvement following correction, therefore, early diagnosis and operation...

Designing high-efficiency photocatalyst for photocatalytic water splitting is a considerable challenge. Herein, new Mn3O4/g-C3N4 p-n heterostructure prepared by an in-situ growth method. The introduction of Mn3O4 can enhance light absorption ability g-C3N4. exhibits outstanding activity hydrogen evolution reaction (HER) efficiency ~2700 ?mol g?1h?1 at ? > 420 nm. For the separate reactions H2 a...

background: this study aimed to investigate the pedicle dimension and angulation in cervicothoracic junction (ctj) using the findings of computed tomographic (ct) to help accurate insertion of pedicular screw. methods: forty three patients with high quality ct images of ctj were evaluated. pedicle width (pw), pedicle height (ph), pedicle axis length (pal), transverse angle (ta) and sagittal ang...

conclusions the severity of pathological changes in renal parenchyma, due to upjo, is a good predictor of renal function recoverability, after pyeloplasty. the orus, with drf > 35%, usually have normal (grade i) renal biopsy and might be expected to present better functional recoverability after pyeloplasty. results this study showed a linear relationship between the severity of histological ch...

Splice junction sequences from a large number of nuclear and viral genes encoding protein have been collected. The sequence CAAG/GTAGAGT was found to be a consensus of 139 exon-intron boundaries (or donor sequences) and (TC)nNCTAG/G was found to be a consensus of 130 intron-exon boundaries (or acceptor sequences). The possible role of splice junction sequences as signals for processing is discu...

A two-dimensional conjugated small molecule (SMPV1) was designed and synthesized for high performance solution-processed organic solar cells. This study explores the photovoltaic properties of this molecule as a donor, with a fullerene derivative as an acceptor, using solution processing in single junction and double junction tandem solar cells. The single junction solar cells based on SMPV1 ex...

There is currently a need for a reliable solid-state reference electrode, especially in applications such as autonomous sensing or long-term environmental monitoring. We present here for the first time a novel solid-state nanofiber junction reference electrode (NFJRE) incorporating a junction consisting of poly(methyl methacrylate) and carbon graphene stacked nanofibers. The NFJRE operates by u...

BACKGROUND Harvested hamstring tendon length has received scant attention in published anterior cruciate ligament (ACL) reconstruction literature, yet length can limit the ability to increase graft diameter by folding the tendon over more than once. Indeed, some ultrashort tendons may be too short to yield a clinically useful graft after being folded over just once. Ultimately, the total length...

background: myasthenia gravis (mg) is the most common disorder of neuromuscular junction in which autoantibodies develop against nicotinic acetylcholine receptor for unknown reasons. the association of immunomodulator genes with different autoimmune disease has been studied in recent years. objective: the aim of this study was to investigate correlation between a genetic variation in stromal ce...
