In-depth characterization of protein and lipid fractions from cow and camel milk (four breeds; CM-1 to 4), their functional and thermal properties and bioactivity upon simulated gastro-intestinal digestion was reported. Results revealed that proteins from cow and camel milk showed a noticeable s...

The gastric digestion behaviours of infant formulae made with goat milk and cow milk, with different ratios of casein to whey protein, were investigated using an in vitro dynamic infant human gastric simulator. The goat milk infant formulae formed smaller flocs of aggregated protein and oil drop...

Cow's milk allergy (CMA) is one of the most common food allergies, especially during childhood. CMA is an immunological mediated adverse reaction to one or more cow's milk proteins, which are normally harmless to a non-allergic individual, as the result of a failure of oral tolerance. ...

Cow and camel milk proteins before and after heat treatment at 80 °C for 60 min were identified using LC/MS and LC–MS/MS following monodimensional electrophoresis. The database used for the identification of camel and cow proteins was set from http://www.uniprot.org/. The obtained results show...

Infant formula products are predominantly manufactured using cow milk protein; goat milk also provides a suitable protein source. In this study, we directly compared cow and goat milk protein digestion using pH and enzyme conditions to simulate infant gastric conditions. Generated peptides, iden...

Alpha-lactalbumin (α-LA) is one of the whey proteins in cows’ milk that has been identified as allergenic. In this work, we present, for the first time, a very sensitive magnetic beads (MBs)-based immunosensor for the determination of α-LA. A sandwich configuration involving selective capture...

In this study, newly modified hydroxyapatite microbeads were used to isolate α-lactalbumin (α-LA) from cow's milk by a single step. Inorganic material, pure hydroxyapatite was embedded in ethylene glycol dimethacrylate (EGDMA) in the presence of pore maker. Newly synthesized hydroxyapatit...

ABSTRACTThe addition of cow milk during the production of buffalo mozzarella is a common fraud in dairy industries because of the lower price and greater availability of cow milk throughout the year. The aim of this study was to develop a new, rapid, and robust capillary electrophoresis method f...

In this study, the composition and microstructure of three whey protein ingredient powders enriched in α-lactalbumin (LAC 1, 2 and 3), prepared using three different enrichment approaches, were assessed to determine their bulk handling (flowability, wall friction, bulk density and compressibili...

The effects of high pressure processing on the binding interactions of α-lactalbumin and pelargonidin-3-glucoside were studied using the fluorescence quenching, molecular dynamic simulation and molecular docking analysis. The results of fluorescence quenching indicated that the high pressure pr...

Camelid α-lactalbumin is the only known protein that can undergo nonenzymatic deamidation on two Asn residues. This leads to the generation of a mixture of unusual isoAsp and d-Asp residues that may impact health. The effect of deamidation on camel α-lactalbumin instability was investigated. C...

We have purified the AaTX1 peptide from the Androctonus australis (Aa) scorpion venom, previously cloned and sequenced by Legros and collaborators in a venom gland cDNA library from Aa scorpion. AaTX1 belongs to the α-Ktx15 scorpion toxins family (αKTx15-4). Characterized members of this famil...

Background and aimScorpion envenomation is a common acute life threatening health problem in developing countries as Egypt. Scorpion venom is a complex structure composed of neurotoxic proteins, salts, acidic proteins, and organic compounds, thereby having of neurologic, cardiovascular, hematolo...

Previous studies showed that venoms of the monocled cobra, Naja kaouthia from Thailand and Malaysia are substantially different in their median lethal doses. The intraspecific venom variations of N. kaouthia, however, have not been fully elucidated. Here we investigated the venom proteomes of N....

The neuromuscular and skeletal muscle actions of Naja naja kaouthia snake venom were studied in mammalian (rat left hemidiaphragm) and avian (chick biventer cervicis) nerve–muscle preparations. The venom (5 and 10 μg/ml) produced neuromuscular blockade (85% in 36.8±2.0 min, mean±SEM, n=5, an...

Structurally similar but functionally different two paralogous proteins, CTX1 (a cardiotoxin) and LNTX2 (an alpha-neurotoxin), from venom of Naja naja naja have been homology modeled and subjected to molecular dynamics (MD) simulations at four different temperatures (298 K, 310 K, 373 K & 473 K)...

The venom proteome of the monocled cobra, Naja kaouthia, from Thailand, was characterized by RP-HPLC, SDS-PAGE, and MALDI-TOF-TOF analyses, yielding 38 different proteins that were either identified or assigned to families. Estimation of relative protein abundances revealed that venom is dominat...

The complex venom proteome of the eastern India (EI) spectacled cobra (Naja naja) was analyzed using tandem mass spectrometry of cation-exchange venom fractions. About 75% of EI N. naja venom proteins were

Naja naja (Indian cobra) from Sri Lanka and India is the WHO Category 1 medically important snakes in both countries. Some antivenom produced against Indian N. naja (NNi) were less effective against Sri Lankan N. naja (NNsl). Proteomes of NNi and NNsl venoms were studied by RP-HPLC, SDS-PAGE and...

An improved chromatographic method was developed to isolate and purify polypeptides and proteins from the crude venom of the Taiwan cobra Naja naja atra. The procedure devised is simple, easy to reproduce, and enables large scale isolation of almost all polypeptides and proteins in this cobra ve...
