Transitory allergies to cow milk proteins in infants or adults have become a public health problem. Although extensively or partially hydrolyzed cow milk protein formulas are available, these products are costly. Therefore, studies into innovative enzymes to digest cow milk proteins are needed. Danaus plexippus gut peptidases were purified and examined with regard to cow milk protein hydrolysis. The peptidases hydrolyzed caseins and whey proteins. However, after heat treatment, there was a significant improvement in β-lactoglobulin hydrolysis. The hydrolyzed cow milk proteins were not recognized by anti-casein antibodies and only reacted slightly with antibodies against whey proteins. This performance was better than that of partially hydrolyzed formulas and similar to that of an extensively hydrolyzed formula. These results suggest that D. plexippus gut peptidases are suitable and innovative enzymes to produce hypoallergenic cow milk protein formulas.

Duck viral hepatitis (DVH) caused by duck hepatitis A virus (DHAV) is a highly contagious and economically important disease of ducklings worldwide. In many parts of the globe, disease outbreaks are reported in spite of vaccinations, probably due to antigenic diversity among DHAV genotypes. We previously reported the first isolation of DHAV-2 (Genotype -2) from ducklings in Tamil Nadu, India.

Determination of hydrogen peroxide (HO) is of great importance in many systems for controlling the quality of products, food safety, and medical diagnostics. In this work, a highly sensitive photoluminescence film sensor was synthesized based on chitosan (CS), polyvinyl alcohol (PVA), and terephthalic acid (TPA), in the presence of copper (II) ions for determination of hydrogen peroxide. TPA was used as a sensitive probe for detection of hydroxyl radicals produced in a photo-Fenton-like process.

Problem: Tongue tie is an added complication when breastfeeding, but little is known about the role tongue tie might play when breastfeeding twins.
Background: Twins are much less likely to be breastfed than singleton babies due to added complications regarding pregnancy, birth and ongoing care. Tongue tie can cause breastfeeding barriers including poor latch, inefficient milk transfer and nipple pain.
A novel electrochemiluminescence sensor based on NiCo NCs@CN QDs nanocomposites with poly-L-cysteine as co-reaction accelerator for ultrasensitive detection of vitamin K.

Electronic address:
A novel electrochemiluminescence (ECL) sensor based on eco-friendly CN QDs was constructed for the ultrasensitive detection of VK. The synthesized NiCo nanocages (NiCo NCs) with large specific surface area and high catalytic activity were used to effectively load CN QDs, forming the nanocomposites (NiCo NCs@CN QDs) with good luminescent properties. After grafting NiCo NCs@CN QDs onto poly-L-cysteine film, the ECL system achieved multiple signal amplification, which was due to the fact that poly-L-cysteine as a co-reactant accelerator sped up the generation of more SO from SO.

We hypothesized that improving the fat globule structure of infant formulae based on the milk fat globule membrane (MFGM) would regulate metabolites and metabolic pathways, making it more similar to the metabolic properties of human milk. Therefore, we prepared infant formulae with different fat globule structures, including two model infant formulae (F1: fat globules surrounded by MFGM; F2: fat globules surrounded by protein) and one commercial infant formulae containing MFGM, and compared their metabolic differences with those of human milk. The number of differential metabolites between each sample and human milk reached 60 (F1), 132 (F2) and 126 (IF1).
