Tuning chitosan properties to enhance blood coagulation.

The search for new hemostatic materials remains a priority for researchers, as the problem of uncontrolled hemorrhage during surgical interventions or traumatic injuries represents a significant challenge. The objective of the study was to identify novel polysaccharide structures with enhanced hemostatic properties based on chitosan. The number of chitosan derivatives with two substituents was synthesized and characterized by H NMR, FTIR.

Protein hydrolysates with ACE-I inhibitory activity from amaranth seeds fermented with Enterococcus faecium-LR9: Identification of peptides and molecular docking.

One of the causes of hypertension is the activity of angiotensin-I converting enzyme (ACEI), making its inhibition a crucial strategy for controlling the disease. Protein hydrolysates are a known source of bioactive peptides that contribute to ACE-I inhibition. This study aims to evaluate the ACE-I inhibitory activity of amaranth seed hydrolysates after fermentation with Enterococcus faecium-LR9 and to compare it with Leuconostoc mesenteroides-18C6 and enzymatic hydrolysis (Alcalase®).

Chitosan-coated manganese ferrite nanoparticles enhanced Rhodotorula toruloides carotenoid production.

The present study aims to analyze the interaction between Rhodotorula toruloides and magnetic nanoparticles and evaluate their effect on carotenoid production. The manganese ferrite nanoparticles were synthesized without chitosan (MnFeO) and chitosan coating (MnFeO-CS) by the co-precipitation method assisted by hydrothermal treatment. XRD (X-ray diffraction), Magnetometry, Dynamic Light Scattering (DLS) and FTIR (Fourier-Transform Infrared Spectroscopy), are used to characterize the magnetic nanoparticles.

[Prospects for use of short peptides in pharmacotherapeutic correction of Alzheimer's disease.].

Alzheimer's disease (AD) is the most common neurodegenerative disorder, characterized by progressive cognitive decline. This review discusses current therapeutic strategies for the treatment of Alzheimer's disease, their limitations, and potential prospects. The feasibility of comprehensive approach for AD therapy is considered in contrast to the classical method in the development of therapeutic strategy.

Autoprobiotics in the Treatment of Patients with Colorectal Cancer in the Early Postoperative Period.

Despite great advances in the treatment of oncological diseases, the development of medical technologies to prevent or reduce complications of therapy, in particular, those associated with surgery and the introduction of antibiotics, remains relevant. The aim of this study is to evaluate the effectiveness of the use of autoprobiotics based on indigenous non-pathogenic strains of and as a personalized functional food product (PFFP) in the complex therapy of colorectal cancer (CRC) in the early postoperative period. A total of 36 patients diagnosed with CRC were enrolled in the study.
