Structural analysis of extracellular ATP-independent chaperones of streptococcal species and protein substrate interactions.

Department of Biological Sciences, University of Pittsburgh, Pittsburgh, Pennsylvania, USA.
Unlabelled: During infection, bacterial pathogens rely on secreted virulence factors to manipulate the host cell. However, in gram-positive bacteria, the molecular mechanisms underlying the folding and activity of these virulence factors after membrane translocation are not clear. Here, we solved the protein structures of two secreted parvulin and two secreted cyclophilin-like peptidyl-prolyl isomerase (PPIase) ATP-independent chaperones found in gram-positive streptococcal species.

We retrospectively analyzed a large international cohort of 1113 patients with aplastic anemia to evaluate treatment choice and outcome in elderly patients as compared with a younger population. Overall, 319 (29%) patients were > 60 years old at diagnosis (60-64 years (n = 85), 106 65-69 years (n = 106), and 128 > 70 years (n = 128)). Elderly patients showed a more severe thrombocytopenia at onset and a significantly lower overall response (complete plus partial) to first-line therapy at 6 months as compared to younger patients (47% vs.

Department of Ophthalmology, Osaka University Graduate School of Medicine, 2-2 Yamadaoka, Suita, Osaka, 565-0871, Japan.
Purpose: To report a case of bilateral choroidal osteoma successfully treated with subscleral sclerectomy for secondary serous retinal detachment (SRD).
Observations: A 52-year-old Japanese woman first diagnosed with Vogt-Koyanagi-Harada disease and treated with steroids for 9 years was referred to our clinic. SRD in both eyes recurred frequently and was uncontrolled with adalimumab subcutaneous injections and oral cyclosporine, in addition to steroids.
Clinical follow-up of 2 families with glomerulopathy caused by gene variants and literature review.

Background: Primary coenzyme Q10 (CoQ10) deficiency is an autosomal recessive genetic disease caused by mitochondrial dysfunction. Variants in Coenzyme Q8B () can cause primary CoQ10 deficiency. -related glomerulopathy is a recently recognized glomerular disease that most often presents as steroid-resistant nephrotic syndrome (SRNS) in childhood.

Department of Dermatology, School of Medicine in Katowice, Medical University of Silesia, Katowice, Poland.
Introduction: Neutrophil gelatinase-associated lipocalin (NGAL) is believed to be involved in the pathogenesis of psoriasis, and its serum level was previously found to decline after administration of biologics, UV, and cyclosporine therapy.
Aim: To investigate whether NGAL may serve as a biomarker of disease activity in psoriasis vulgaris.
Material And Methods: To measure the level of NGAL in serum, 36 patients with psoriasis vulgaris and 33 healthy controls were enrolled.
