This work investigated the influence of carbohydrates, proteins and lipids on the anaerobic digestion of food waste (FW) and the relationship between the parameters characterising digestion. Increasing the concentrations of proteins and lipids, and decreasing carbohydrate content in FW, led to high buffering capacity, reduction of proteins (52.7-65.0%) and lipids (57.4-88.2%), and methane production (385-627 mLCH4/g volatile solid), while achieving a short retention time. There were no significant correlations between the reduction of organics, hydrolysis rate constant (0...

Rising atmospheric CO2 causes ocean acidification that represents one of the major ecological threats for marine biota. We tested the hypothesis that long-term exposure to increased CO2 level and acidification in a natural CO2 vent system alters carbon (C) and nitrogen (N) metabolism in Posidonia oceanica L. (Delile), affecting its resilience, or capability to restore the physiological homeostasis, and the nutritional quality of organic matter available for grazers. Seawater acidification decreased the C to N ratio in P...

The recycling of biosolids and livestock manure in agriculture may lead to the introduction of antibiotic residues, i.e., parent molecule and transformation products, into amended soils. Their fate in soils can be approached through the assessment of their environmental availability. In this work, the environmental availability of sulfamethoxazole (SMX) and three transformation products (N(4)-acetyl-SMX, 3-amino-5-methylisoxazole, aniline) was assessed in soils amended with sludge compost or cow manure throughout a three-month incubation, using soft extractions with CaCl2, EDTA or cyclodextrin solutions...

A facile and scalable method has been realized for the in-situ synthesis of N/S co-doping 3D porous carbon nanosheet networks (NSPCNN) as sodium-ion battery anode material. During the synthesis, NaCl is used for a template to prepare porous carbon nanosheet networks. In the resultant architecture, the unique 3D porous architecture ensures large specific surface area and fast diffusion path of both electrons and ions. Meanwhile, the import of N/S produces abundant defects, increased interlayer space, more active sites and high electronic conductivity...

Myo-inositol (MYO) usually represents a therapeutic option for female infertility associated with insulin resistance. Recently, several evidences are accumulating about the potential use of MYO for the treatment of male infertility. This article summarizes the rationale for MYO in the treatment of male infertility. In particular, it illustrates the potential antioxidant and prokinetic role of MYO, and its importance for the modulation of hormonal regulation. In the final part of the manuscript has been added a proposal for a clinical algorithm reserved for patients with asthenozoospermia, where probably MYO could exert specific pharmacological effects...

Three factors that directly affect the water inputs in cropping systems are root architecture, length of the growing season, and stomatal conductance to water vapor (). Deeper-rooted cultivars will perform better under water-limited conditions because they can access water stored deeper in the soil profile. Reduced limits transpiration rate () and thus throughout the vegetative phase conserves water that may be used during grain filling in water-limited environments. Additionally, growing early-maturing varieties in regions that rely on soil-stored water is a key water management strategy...

Bread wheat ( L.) is one of the most important crops worldwide. Although a reference genome sequence would represent a valuable resource for wheat improvement through genomics-assisted breeding and gene cloning, its generation has long been hampered by its allohexaploidy, high repeat content, and large size. As a part of a project coordinated by the International Wheat Genome Sequencing Consortium (IWGSC), a physical map of the short arm of wheat chromosome 3D (3DS) was prepared to facilitate reference genome assembly and positional gene cloning...

This article examines the structural approach to health cooperation, focusing on its meaning as a method for promoting institutional policies to improve management models. We draw attention to the differences between this approach and the traditional disease-based approach, showing that the structural approach is centered on health systems, reinforces global governance, and embodies the Sustainable Development Goals (SDG), thus taking on a multi-sectoral dimension. This approach leverages the maximum potential of international cooperation by establishing structuring networks and promoting relations between partner countries through their national health institutions, schools of public health, and technical staff...

Lymphatic dysfunction is associated with the progression of many cardiovascular disorders due to their role in maintaining tissue fluid homeostasis. Promoting new lymphatic vessels (lymphangiogenesis) is a promising strategy to reverse these cardiovascular disorders via restoring lymphatic function. Vascular endothelial growth factor (VEGF) members VEGF-C and VEGF-D are both potent candidates for stimulating lymphangiogenesis, though maintaining spatial and temporal control of these factors represents a challenge to developing efficient therapeutic lymphangiogenic applications...
