The clinical spectrum of leishmaniasis depends on several factors, including Leishmania species and immunogenetic factors. Tumor necrosis factor α (TNFα) plays a central role in immunity against intracellular infections. Many studies have reported that TNFα-308G > A polymorphism is associated with susceptibility to intracellular infections and influences TNFα production. Some studies on the implications of TNFα-308G > A polymorphism in the susceptibility to cutaneous leishmaniasis and visceral leishmaniasis showed controversial results...

The oculocerebrorenal disorder of Lowe syndrome is an X-linked mutation in the gene oculocerebrorenal syndrome of Lowe 1 (OCRL), characterized by the triad of congenital cataracts, severe intellectual impairment, and renal tubular dysfunction. Manifestations of phenotype in female carriers and patients are extremely rare. We present a female case with congenital cataracts, severe intellectual impairment, sensorineural hearing loss, and renal tubular dysfunction as Lowe syndrome. A 9-year-old Japanese girl visited our hospital due to prolonged proteinuria...

BACKGROUND: Lowe syndrome (LS) is an X-linked recessive disorder caused by mutations in OCRL , which encodes the enzyme OCRL. Symptoms of LS include proximal tubule (PT) dysfunction typically characterized by low molecular weight proteinuria, renal tubular acidosis (RTA), aminoaciduria, and hypercalciuria. How mutant OCRL causes these symptoms isn't clear. METHODS: We examined the effect of deleting OCRL on endocytic traffic and cell division in newly created human PT CRISPR/Cas9 OCRL knockout cells, multiple PT cell lines treated with OCRL -targeting siRNA, and in orcl -mutant zebrafish...

The aim of present study was to check the possible association of potential parental environmental exposures and maternal supplementation intake with the risk of nonsyndromic orofacial clefting (NSOC). A retrospective study comprised 499 cases and 480 controls was conducted in Heilongjiang Province. Chi-square analysis and unconditional multiple logistic regression were used in the study. The results showed that maternal history of fever and the common cold without fever (ORCL/P = 3.11 and 5.56, 95%CI: 1.67-5...

Purpose. To investigate the outcome and toxicity of stereotactic body radiotherapy (SBRT) in patients with oligo-recurrence cancer in the lung (ORCL). Methods and Materials. A retrospective review of 42 patients with ORCL who underwent SBRT in our two hospitals was conducted. We evaluated the outcome and adverse effects after SBRT for ORCL. Results. All patients finished their SBRT course without interruptions of toxicity reasons. The median follow-up period was 20 months (range, 1-90 months). The 2-year local control rate and overall survival were 87% (95% CI, 75-99%) and 65% (95% CI, 48-82%)...

1. An outwardly rectifying Cl- (ORCl) current of murine osteoclasts was activated by hypotonic stimulation. The current was characterized by rapid activation, little inactivation, strong outward rectification, blockage by DIDS and permeability to organic acids (pyruvate and glutamate). 2. The hypotonically activated ORCl current was inhibited by intracellular dialysis with an ATP-free pipette solution, but not by replacement of ATP with a poorly hydrolysable ATP analogue adenosine 5'-O-(3-thiotriphosphate)...

Effects of the extracellular Ca2+ concentration ([Ca2+]o) on whole cell membrane currents were examined in mouse osteoclastic cells generated from bone marrow/stromal cell coculture. The major resting conductance in the presence of 1 mm Ca2+ was mediated by a Ba2+-sensitive, inwardly rectifying K+ (IRK) current. A rise in -Ca2+-o (5-40 mM) inhibited the IRK current and activated an 4'4'-diisothiocyano-2,2'-stilbenedisulfonate (DIDS)-sensitive, outwardly rectifying Cl- (ORCl) current. The activation of the ORCl current developed slowly and needed higher [Ca2+]o than that required to inhibit the IRK current...

Rat mucosal type mast cells are thought to possess only a K+-selective inwardly rectifying (IRK) current in the resting state. We used rat-bone-marrow-derived mast cells (BMMCs) as a model of mucosal mast cells and recorded whole-cell membrane currents from cells perforated with amphotericin B. Under these conditions, both inwardly rectifying (IR) and outwardly rectifying (OR) currents were observed. The reversal potential and conductance of the IR current depended on the extracellular K+ concentration, indicating that the channel was K+ selective...

Transport vesicles derived from the Golgi apparatus are thought to mediate biosynthetic transport across the Golgi stack. These vesicles are surrounded by a protein coat whose principal constituents are coatomer (a complex of seven distinct subunits or COPs) and ADP-ribosylation factor (ARF, an N-myristylated small GTP-binding protein). The coat proteins of the COP-coated vesicles were originally defined by ultrastructural criteria, however, and it is possible that important but minor coat proteins or cytoplasmic proteins needed for coat assembly may have been overlooked...
