Fungal loosenin-like proteins boost the cellulolytic enzyme conversion of pretreated wood fiber and cellulosic pulps.

Microbial expansin-related proteins, including loosenins, can disrupt cellulose networks and increase enzyme accessibility to cellulosic substrates. Herein, four loosenins from Phanerochaete carnosa (PcaLOOLs), and a PcaLOOL fused to a family 63 carbohydrate-binding module, were compared for ability to boost the cellulolytic deconstruction of steam pretreated softwood (SSW) and kraft pulps from softwood (ND-BSKP) and hardwood (ND-BHKP). Amending the Cellic® CTec-2 cellulase cocktail with PcaLOOLs increased reducing products from SSW by up to 40 %, corresponding to 28 % higher glucose yield.

[Widespread preoperative hair removal in the southwest of The Netherlands despite an evidence-based guideline discouraging this practice].

Objective: To determine whether the 1993 guideline from the Dutch Institute for Healthcare Improvement (CBO) is followed in the Southwest region of the Netherlands. The guideline states that preoperative hair removal serves no purpose in preventing wound infection.

Design: Inventory.

[Submucosal lipoma of the colon: abdominal cramps with rectal bleeding and weight loss].

An 81-year-old woman had abdominal cramps, rectal bleeding since 2 weeks and weight loss. Colonoscopy showed an ulcerating tumour of about 4 cm in the transverse colon. Pathological examination of biopsies taken during colonoscopy indicated moderately active chronic colitis.

[The surgical treatment of Graves' disease].

A man aged 80 and three women aged 66, 26, and 39 years respectively, underwent surgery for Graves' disease. The first woman had pneumonia and experienced thyrotoxic storm. Euthyroidism was restored with antithyroid drugs (ATD) and thyroidectomy was performed as ablative treatment for hyperthyroidism.
