Overcoming resistance to arginine deprivation therapy using GC7 in pleural mesothelioma.

Pleural mesothelioma is a highly chemotherapy-resistant cancer. Approximately 50% of mesotheliomas do not express argininosuccinate synthetase 1 (ASS1), the rate-limiting enzyme in arginine biosynthesis, making arginine depletion with pegylated arginine deiminase (ADI-PEG20) an attractive therapeutic strategy. We investigated whether combinatory treatment composed of ADI-PEG20 and polyamine inhibitors constitutes a promising novel therapeutic strategy to overcome ADI-PEG20 resistance in mesothelioma patients.

Guidelines for Diagnosis of Noise-Induced Hearing Loss and Their Specificity.

Objectives: A recent paper by Moore, Lowe and Cox has proposed guidelines for diagnosing noise-induced hearing loss (NIHL). It is referred to here as the MLC guidelines. Our aim was to assess the specificity of those guidelines (i.

Phosphorus-containing polycarbosilazanes: synthesis dehydrocoupling catalysis and flame-retardant properties.

The barium complex [Ba{N(SiMe)}] has been used to catalyse the dehydropolymerisation of the phosphine-functionalised hydrosilane 4-PhP-CHSiH (A) with the α,ω-diamine 1,4-(CHNHMe)-CH (C), for the production of -[Si(4-CHPPh)H-N(Me)CH-CH-CHN(Me)]- polycarbosilazanes that contain dangling phosphino groups along the polymer backbone. The comonomers A and C, specifically prepared for this purpose and comprehensively characterised, lend themselves well to barium-promoted dehydrocoupling catalysis. They allow for the formation of linear, amine-capped polymers with molecular weights in the range 4000-8000 g mol, as estimated by DOSY and H end-group NMR analyses.

Common soluble carbohydrates affect the growth, survival, and fatty acid profile of black soldier fly larvae Hermetia illucens (Stratiomyidae).

The black soldier fly, Hermetia illucens (L. 1758), is an omnivorous saprophagous insect with a high potential for valorizing organic by-products rich in carbohydrates. Among carbohydrates, H.

Microorganism Contribution to Mass-Reared Edible Insects: Opportunities and Challenges.

The interest in edible insects' mass rearing has grown considerably in recent years, thereby highlighting the challenges of domesticating new animal species. Insects are being considered for use in the management of organic by-products from the agro-industry, synthetic by-products from the plastics industry including particular detoxification processes. The processes depend on the insect's digestive system which is based on two components: an enzymatic intrinsic cargo to the insect species and another extrinsic cargo provided by the microbial community colonizing-associated with the insect host.
