Food allergies represent a serious problem affecting human health and soy proteins rank among the most allergenic proteins from food origin. The proteolytic enzymes produced by lactic acid bacteria (LAB) can hydrolyse the major allergens present in soybean, reducing their immunoreactivity. Many studies have reported the ability of LAB to ferment soy-based products; while the majority of them focus on the improvement of the sensory characteristics and functionality of soy proteins, a lack of information about the role of lactic fermentation in the reduction of immunoreactivity of these proteins exists...

Osteoporosis is a systemic skeletal disorder which occurs when the bone turnover balance is disrupted. With the identification of the genes involved in the pathogenesis of the disease, studies on development of new osteoporosis treatments has intensified. RNA interference (RNAi) mechanism uses short interfering RNA (siRNA) to knockdown disease related gene expression as a treatment approach. Targeting while protecting siRNA against hydrolysis by nucleases in vivo is, however, challenging. The maintenance of therapeutic plasma level is also hampered by the clearance of siRNA from the body...

Lactobacillus casei,Lactobacillus paracasei and Lactobacillusrhamnosus form a closely related taxonomic group (the L. casei group) within the facultatively heterofermentative lactobacilli. Strains of these species have been used for a long time as probiotics in a wide range of products, and they represent the dominant species of nonstarter lactic acid bacteria in ripened cheeses, where they contribute to flavour development. The close genetic relationship among those species, as well as the similarity of biochemical properties of the strains, hinders the development of an adequate selective method to identify these bacteria...
