These results were confirmed by HPV genotyping using microdissected koilocytes in 27 patients.Most common high-risk types belonging to α-9 and α-7 genotypes appear to rarely induce koilocytic changes. Therefore, koilocytes may provide additional useful information for predicting the risk of progression to high-grade lesions. © 2020 Wiley Periodicals, Inc.BACKGROUND Congenital adrenal hyperplasia (CAH) is an autosomal recessive condition which leads to glucocorticoid deficiency and is the most common cause of adrenal insufficiency in children. In over 90% of cases, 21-hydroxylase enzyme deficiency is found which is caused by mutations in the 21-hydroxylase gene. Managing individuals with CAH due to 21-hydroxylase deficiency involves replacing glucocorticoids with oral glucocorticoids (including prednisolone and hydrocortisone), suppressing adrenocorticotrophic hormones and replacing mineralocorticoids to prevent salt wasting. During childhood, the main aims of treatment are to prevent adrenal crises and to achieve normal stature, optimal adult height and to undergo normal puberty. In adults, treatment aims to prevent adrenal crises, ensure normal fertility and to avoid the long-term consequences of glucocorticoid use. Current glucocorticoid treatment regimens can not optimally replicate the normal physiological cortisol level and over-treatment or under-treatm trials examining a modified-release formulation of HC or use of 24-hour circadian continuous subcutaneous infusion of hydrocortisone. As a consequence, uncertainty remains about the most effective form of glucocorticoid replacement therapy in CAH for children and adults. Future trials should include both children and adults with CAH. A longer duration of follow-up is required to monitor biochemical and clinical outcomes. Copyright © 2020 The Cochrane Collaboration.

Shake flasks and bench-scale bioreactor systems are still the golden standard in the early stage of bioprocess development, though they are known to be expensive, time-consuming and labour-intensive as well as lacking the throughput for efficient production optimizations. To bridge the technological gap between bioprocess optimization and upscaling, we have developed a microfluidic bioreactor array to reduce time and costs, and to increase throughput compared to traditional lab-scale culture strategies. We present a multifunctional microfluidic device containing 12 individual bioreactors (Vt = 15 µL) in a 26 mm x 76 mm area with in-line biosensing of dissolved oxygen and biomass concentration. Following initial device characterization, the bioreactor lab-on-a-chip was used in a proof-of-principle study to identify the most productive cell line for lactic acid production out of two engineered yeast strains, evaluating whether it could reduce the time needed for collecting meaningful data compared to shake flasks cultures. Autophinib ic50 Results of the study showed significant difference in the strains' productivity within 3 hours of operation exhibiting a 4- to 6-fold higher lactic acid production, thus pointing at the potential of microfluidic technology as effective screening tool for fast and parallelizable industrial bioprocess development.

Water-soluble polyPs with average chain lengths of 2 to 40 P-subunits are widely used as food additives and are currently synthesized chemically. An environmentally-friendly highly scalable process to biosynthesize water-soluble food-grade polyP in powder form (termed bio-polyP) is presented in this study. After incubation in a phosphate-free medium, Generally-Regarded-As-Safe (GRAS) wild-type baker's yeast (Saccharomyces cerevisiae) took up phosphate and intracellularly polymerized it into 26.5 % polyP (as KPO3 , in cell dry weight). The cells were lysed by freeze-thawing and gentle heat treatment (10 min, 70°C). Protein and nucleic acid were removed from the soluble cell components by precipitation with 50 mM HCl. Two chain length fractions (42 and 11 P-subunits average polyP chain length, purity on a par with chemically produced polyP) were obtained by fractional polyP precipitation (fraction 1 was precipitated with 100 mM NaCl and 0.15 vol ethanol, and fraction 2 with 1 final vol ethanol), drying, and milling. The physicochemical properties of bio-polyP were analyzed with an enzyme assay, 31 P nuclear magnetic resonance spectroscopy, and polyacrylamide gel electrophoresis, among others. An envisaged application of the process is phosphate recycling from waste streams into high-value bio-polyP. This article is protected by copyright. All rights reserved.

When possible, reconstruction with scapular allograft is the gold standard, and gives satisfactory functional, cosmetic, and oncological outcomes. While good results have recently been reported with 3D-printed prostheses for reconstruction of bone loss, there is little information available in the medical literature regarding scapula reconstruction with a 3D-printed prosthesis. Between 2016 and 2018, we performed four scapular resections (two total and two involving the superior 1/3) followed by reconstruction with a 3D-printed prosthesis made of a porous titanium alloy (Ti-6Al-4V, diameter between 100 and 400 mm), using computer-aided design (CAD) and patient-specific implants (PSI) with previously acquired CT-MR fusion images. At 2 years follow-up, the patients with partial scapulectomy had an MSTS score of 76%, no local or systemic recurrence, good clinical results and no pain. At 1 year 6 months follow-up, the patients with total scapulectomy had an MSTS score of 46%, no local or systemic recurrence, fair clinical results and no pain. Thus, custom-made 3D-printed prostheses appear to be valuable in orthopedic surgery. However, a larger cohort and longer-term analysis are needed to evaluate the scapular 3D-printed prosthesis as a reliable reconstruction technique.
