Copper-loaded Milk-Protein Derived Microgel Preserves Cardiac Metabolic Homeostasis After Myocardial Infarction.

Myocardial Infarction (MI) is a leading cause of death worldwide. Metabolic modulation is a promising therapeutic approach to prevent adverse remodeling after MI. However, whether material-derived cues can treat MI through metabolic regulation is mainly unexplored.

Rapid UV Photo-Cross-Linking of α-Lactalbumin Hydrogel Biomaterial To Enable Wound Healing.

Although both the function and biocompatibility of protein-based biomaterials are better than those of synthetic materials, their usage as medical material is currently limited by their high costs, low yield, and low batch-to-batch reproducibility. In this article, we show how α-lactalbumin (α-LA), rich in tryptophan, was used to produce a novel type of naturally occurring, protein-based biomaterial suitable for wound dressing. To create a photo-cross-linkable polymer, α-LA was methacrylated at a 100-g batch scale with >95% conversion and 90% yield.

Supplementing maternal diet with milk oligosaccharides and probiotics helps develop the immune system and intestinal flora of offsprings.

Intestinal flora is very important for improving the development of the immune system in newborns. Maternal diet during pregnancy and lactation is one of the key factors affecting the growth and development of offspring. The objective of the present study was to examine whether supplementation of maternal diet with milk oligosaccharides and could influence the development of the intestinal flora and immune system of neonatal mice.

White-light crosslinkable milk protein bioadhesive with ultrafast gelation for first-aid wound treatment.

Background: Post-traumatic massive hemorrhage demands immediately available first-aid supplies with reduced operation time and good surgical compliance. In-situ crosslinking gels that are flexibly adapting to the wound shape have a promising potential, but it is still hard to achieve fast gelation, on-demand adhesion, and wide feasibility at the same time.

Methods: A white-light crosslinkable natural milk-derived casein hydrogel bioadhesive is presented for the first time.

Scalable Milk-Derived Whey Protein Hydrogel as an Implantable Biomaterial.

There are limited naturally derived protein biomaterials for the available medical implants. High cost, low yield, and batch-to-batch inconsistency, as well as intrinsically differing bioactivity in some of the proteins, make them less beneficial as common implant materials compared to their synthetic counterparts. Here, we present a milk-derived whey protein isolate (WPI) as a new kind of natural protein-based biomaterial for medical implants.

Lipidomics phenotyping of clam (Corbicula fluminea) through graphene/fibrous silica nanohybrids based solid-phase extraction and HILIC-MS analysis.

Polyunsaturated phospholipids are abundant in clam (Corbicula fluminea) but difficult to be fully extracted. Herein, graphene/fibrous silica (G/KCC-1) nanohybrids were synthesized, characterized, and applied for solid-phase extraction (SPE) of phospholipids in clam. The effectiveness of G/KCC-1 SPE was verified by hydrophilic interaction chromatography mass spectrometry (HILIC-MS) based lipidomics and statistical analysis.

Real-Time Screening of Omega-7 Phospholipids in Marine Biological Resources Using an iKnife-Rapid-Evaporative-Ionization-Mass-Spectrometry-Based Lipidomics Phenotype.

Omega-7 (n-7) phospholipids were bioactive substances in marine animals. In this study, a fast lipidomics phenotyping approach for real-time screening of n-7 phospholipids in five kinds of economic seafood, salmon, prawn, bluefin tuna, hairtail, and butterfish, was established using iKnife rapid evaporative ionization mass spectrometry (REIMS). The n-7 phospholipids were structurally characterized and quantitatively analyzed, and the profiles were statistically analyzed by multivariate recognition analysis.

Titania-coated fibrous silica (TiO/KCC-1) core-shell microspheres based solid-phase extraction in clam (Corbicula fluminea) using hydrophilic interaction liquid chromatography and mass spectrometry.

Clam (Corbicula fluminea) contains significant amount of phospholipids, and the profile of phospholipids could be used as an index for nutrition evaluation. In this study, a titania-coated fibrous silica (TiO/KCC-1) core-shell microsphere based solid-phase extraction (SPE) and hydrophilic interaction liquid chromatography mass spectrometry (HILIC-MS) method was developed to study the phospholipids in clam. The structure and morphology of TiO/KCC-1 were characterized by transmission electron microscopy (TEM), scanning electron microscope (SEM), X-ray diffraction (XRD), and ultraviolet-visible diffuse reflectance spectroscopy (UV-vis DRS).

Rapid diagnosis of largemouth bass ranavirus in fish samples using the loop-mediated isothermal amplification method.

Largemouth bass ranavirus (LMBV) has been recognized as the causative pathogen responsible for infectious skin ulcerative syndrome in cultured largemouth bass in China. A fast and simple LMBV detection method is urgently needed. Here, a loop-mediated isothermal amplification (LAMP) assay was established for the detection of this virus using primers targeting the major capsid protein gene of LMBV.

The chemokine CXCL9 expression is associated with better prognosis for colorectal carcinoma patients.

The chemokine CXCL9 has been demonstrated to play an important role in the development of human malignancies. However, its prognostic significance in cancer patients remains unclear and less is known about its role in colonrectal carcinoma (CRC) patients. In this study, we found that the relative mRNA expression level of CXCL9 in primary colorectal tumor tissues was significantly higher than that in corresponding normal colon tissues.
