Patients with end-stage renal disease (ESRD) undergoing chronic hemodialysis are at an increased risk of developing spondylodiscitis, an infectious condition affecting the vertebral column. In this case report, we present a 22-year-old male with ESRD, a history of hyperoxaluria, nephrolithiasis, and anemia, who developed spondylodiscitis. Notably, pathological examination of tissue samples obtained during surgical intervention revealed the presence of polarized calcium oxalate crystals within the lumbar laminae and spinal discs, a rare finding in this clinical context.

Department of Microbiology, Faculty of Medicine, Tabriz University of Medical Science, Tabriz, Iran.

Microbiota refers to a collection of living microorganisms, including bacteria, yeasts, and viruses, that coexist in various sites of the human body. Microbiota can perform multiple functions in the body, which have an essential effect on human health and homeostasis. For example, the microbiota can digest polysaccharides, produce vitamins, modulate the immune system, and protect the body against pathogens.

Flavonoids and the gut microbiome: a powerful duo for brain health.

Crit Rev Food Sci Nutr

December 2024

Department of Molecular Biotechnology, Cell Science Research Center, Royan Institute for Biotechnology, ACECR, Isfahan, Iran.

Flavonoids, a class of polyphenolic compounds, are widely distributed in plant-based foods and have been recognized for their potential to promote overall health and well-being. Flavonoids in fruits and vegetables offer various beneficial effects such as anti-aging, anticancer, and anti-inflammatory properties. Flavonoids have been extensively studied for their neuroprotective properties, which are attributed to their ability to cross the blood-brain barrier and interact with neural cells.

The antigen-targeting to dendritic cells (DCs) has gained increasing attention as the potential approach for immunotherapy in recent years due to the ability of DCs to regulate innate and adaptive immunity. In the present study, the immunogenicity and protective efficiency of mannan-decorated PLGA nanoparticles (NPs) loaded with multi-epitopes mycobacterium tuberculosis antigen (HspX-Ppe44-EsxV) were evaluated as a targeted delivery system to DCs. For this purpose, PLGA nanoparticle formulations were prepared and subsequently decorated by mannan.

Human T-lymphotropic virus type 1 (HTLV-1), leads to adult T-cell lymphoma/leukemia (ATL) and HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) in a minority of infected individuals. The virus promotes inflammation, a major factor in chronic disease progression. Probiotics' immune modulation and anti-inflammatory effects present a potential therapeutic intervention for HTLV-1-related conditions.
