Heterotrophy Compared to Photoautotrophy for Growth Characteristics and Pigment Compositions in Batch Cultures of Four Green Microalgae.

Four strains of green microalgae (, , , and ) were compared to determine growth and pigment composition under photoautotrophic or heterotrophic conditions. Batch growth experiments were performed in multicultivators with online monitoring of optical density. For photoautotrophic growth, light-limited (CO-sufficient) growth was analyzed under different light intensities during the exponential and deceleration growth phases.

Percutaneous transhepatic or endoscopic ultrasound-guided biliary drainage in malignant distal bile duct obstruction using a self-expanding metal stent: Study protocol for a prospective European multicenter trial (PUMa trial).

Background: Endoscopic ultrasound-guided biliary drainage (EUS-BD) was associated with better clinical success and a lower rate of adverse events (AEs) than fluoroscopy-guided percutaneous transhepatic biliary drainage (PTBD) in recent single center studies with mainly retrospective design and small case numbers (< 50). The aim of this prospective European multicenter study is to compare both drainage procedures using ultrasound-guidance and primary metal stent implantation in patients with malignant distal bile duct obstruction (PUMa Trial).

Methods: The study is designed as a non-randomized, controlled, parallel group, non-inferiority trial.

A Fast-Growing Oleaginous Strain of Capable of Astaxanthin and Canthaxanthin Accumulation in Phototrophy and Heterotrophy.

Considering the importance of microalgae as a promising feedstock for the production of both low- and high-value products, such as lipids and pigments, it is desirable to isolate strains which simultaneously accumulate these two types of products and grow in various conditions in order to widen their biotechnological applicability. A novel freshwater strain from the genus was isolated in Belgium. Compared to other species, the isolate presented rapid growth in phototrophy, dividing 3.

Impact of expert pathology review in skin adnexal carcinoma diagnosis: Analysis of 2573 patients from the French CARADERM network.

Purpose: To prospectively assess the impact of expert pathological review of skin adnexal carcinoma diagnosis in France.

Methods: From 2014 to 2019, 2573 samples from patients with newly diagnosed or suspected skin adnexal carcinomas were reviewed prospectively by expert pathologists through the national CARADERM (CAncers RAres DERMatologiques) network. Changes in diagnosis between referral and expert review were analysed regarding their potential impact on patient care or prognosis.

Risk Factors for Rapid Chondrolysis After Partial Lateral Meniscectomy: A Scoping Review of the Literature.

Background: The occurrence of rapid chondrolysis after partial lateral meniscectomy is rare. The pathophysiology, risk factors, and outcomes of treatment have not been established.

Purpose: The primary aim of this study was to perform a scoping review of the literature to determine the potential risk factors and pathogenesis of rapid chondrolysis.
