Membranes produced by crosslinking chitosan with magnesium phytate were prepared using highly deacetylated chitosan and its -carboxymethyl, -carboxymethyl and ,-carboxymethyl derivatives. The conditions of the membrane production were described. IR, Raman, electron absorption and emission spectra were measured and analyzed for all the substrates. It was found that -carboxymethyl chitosan derivative is the most effectively crosslinked by magnesium phytate, and the films formed on this substrate exhibit good mechanical parameters of strength, resistance and stability. Strong O-H···O hydrogen bonds proved to be responsible for an effective crosslinking process. Newly discovered membrane types produced from chitosan and magnesium phytate were characterized as morphologically homogenous and uniform by scanning electron microscopy (SEM) and IR measurements. Due to their good covering properties, they do not have pores or channels and are proposed as packaging materials.

Ectopic calcifications in the musculoskeletal field: the basis for preventive and curative pharmacological strategies.
Clin Rheumatol

Center for Physical Medicine and Rehabilitation, University Clinical Center of Serbia, Belgrade, Serbia.
Ectopic calcifications occur in tendons, ligaments, entheses, muscles, and fasciae, and are often associated with pain and inflammation. In clinical settings, these calcifications are commonly treated by physical therapy and/or surgical interventions. However, there is not enough understanding of pharmacological treatments as primary cures, supportive therapy to physical or surgical treatment, or even preventive measures to avoid or diminish the development of ectopic calcifications.

Low phosphorus (P) use efficiency significantly impacts rice yields. An environmentally friendly approach to increase phosphorus absorption and utilization in rice involves the exploration of phosphorus-solubilizing fungal resources. This study aimed to isolate and characterize fungal strains from the rice rhizosphere and assess their phosphate solubilization capabilities, plant-growth-promoting (PGP) traits, and mechanisms involved.

The extrudates were processed using a twin screw extruder and analyzed for their nutritional and anti-nutritional properties. The findings revealed a rising pattern in the content of fiber, moisture, protein, ash and fat as the substitution of Bambara groundnut increased in the extrudate.

Background/objectives: Baobab ( L.) is an underutilized species and edible parts (fruits, leaves and seeds) contribute to food security and human health in tropical areas. Although the fruits have attracted greater research interest and have recently been approved for consumption in EU countries, the leaves are traditionally consumed but they have yet to be studied from an interventional perspective.

Insufficient absorption of iron and the consequent development of iron deficiency have serious health consequences. Hence, identification and development of iron delivery systems that can increase the bioavailability and uptake of dietary iron are important. Osteopontin (OPN) is an acidic and highly phosphorylated integrin-binding protein found in milk where it exists as a full-length protein and as N-terminally derived fragments.
