Previously, polyunsaturated fatty acids (PUFA) from linseed oil were effectively protected (>80%) against biohydrogenation through polyphenol-oxidase-mediated protein crosslinking of an emulsion, prepared with polyphenol oxidase (PPO) extract from potato tuber peelings. However, until now, emulsions of only 2 wt% oil have been successfully protected, which implies serious limitations both from a research perspective (e.g. in vivo trials) as well as for further upscaling toward practical applications. Therefore, the aim of this study was to increase the oil/PPO ratio...

To date, no extensive literature review exists regarding potential uses of mung bean proteins and peptides. As mung bean has long been widely used as a food source, early studies evaluated mung bean nutritional value against the Food and Agriculture Organization of the United Nations (FAO)/the World Health Organization (WHO) amino acids dietary recommendations. The comparison demonstrated mung bean to be a good protein source, except for deficiencies in sulphur-containing amino acids, methionine and cysteine...

Hypertension is the leading risk factor for cardiovascular and chronic renal diseases, affecting more than 1 billion people. Fish intake is inversely correlated with the prevalence of hypertension in several, but not all, studies, and intake of fish oil and fish proteins has shown promising potential to delay development of high blood pressure in rats. The effects of baked and raw salmon fillet intake on blood pressure and renal function were investigated in obese Zucker fa/fa rats, which spontaneously develop hypertension with proteinuria and renal failure...

To improve the health of patients with end-stage renal disease, there is a clear need for slow, continuous hemodialysis, and the pri-mary barrier to a wearable device is the requirement of a large reservoir of dialysate. We describe an electrokinetic means of produc-ing dialysate from the excess fluid extent in the peripheral blood of patients undergoing therapy. A critical feature of this process is the retention of essential components of blood - especially serum albumin. In progress towards this goal, we demonstrate the sepa-ration of charged from neutral species in blood plasma at a branched microchannel junction by ion concentration polarization (ICP)...

Arbuscular mycorrhizal (AM) fungi can significantly contribute to plant nitrogen (N) uptake from complex organic sources, most likely in concert with activity of soil saprotrophs and other microbes releasing and transforming the N bound in organic forms. Here, we tested whether AM fungus (Rhizophagus irregularis) extraradical hyphal networks showed any preferences towards certain forms of organic N (chitin of fungal or crustacean origin, DNA, clover biomass, or albumin) administered in spatially discrete patches, and how the presence of AM fungal hyphae affected other microbes...

For further research and application of Bioartificial liver systems (BAL), active proliferation capacity and full hepatic functionality of the biomaterials is mandatory. However, there are still no suitable cell lines meeting the requirements for an ideal cell source in BAL development that makes it necessary to explore other sources. Here, we constructed a new cell line derived from well-differentiated hepatocellular carcinoma tissues designated NHBL2. Immunol staining showed that NHBL2 possessed the capacity of synthesizing albumin and CYP2E1 and quantitative analysis showed that the albumin synthesis ability of NHBL2 was comparable to C3A while urea production was highly abundant of NHBL2 compared with that of C3A...

For three-dimensional bio-printed cell-laden hydrogel tissue constructs, the well-designed internal porous geometry is tailored to obtain the desired structural and cellular properties. However, significant differences often exist between the designed and as-printed scaffolds because of the inherent characteristics of hydrogels and cells. In this study, an iterative feedback bio-printing (IFBP) approach based on optical coherence tomography (OCT) for the fabrication of cell-laden hydrogel scaffolds with optimal geometrical fidelity and cellular controllability was proposed...

Mild, asymptomatic elevations (less than five times the upper limit of normal) of alanine transaminase and aspartate transaminase levels are common in primary care. It is estimated that approximately 10% of the U.S. population has elevated transaminase levels. An approach based on the prevalence of diseases that cause asymptomatic transaminase elevations can help clinicians efficiently identify common and serious liver disease. The most common causes of elevated transaminase levels are nonalcoholic fatty liver disease and alcoholic liver disease...

Background: Kidney tubular cells are the main sources of Klotho, a protein with phosphaturic action. Genetic Klotho deficiency causes premature cardiovascular aging in mice. Human chronic kidney disease (CKD) is characterized by acquired Klotho deficiency. Despite the lack of uremic toxin accumulation, Category G1 CKD [(normal glomerular filtration rate (GFR)] is already associated with decreased Klotho and with premature cardiovascular aging. Methods: We have explored whether albuminuria, a criterion to diagnose CKD when GFR is normal, may directly decrease Klotho expression in human CKD, preclinical models and cultured tubular cells...

BACKGROUND: Ticks and tick-borne diseases are of major public health concern. Currently, development of vaccines against ticks is considered crucial for their control. A critical step in this process is the screening of viable antigens. Faeces are byproducts of digestion and blood meal utilization, and partly reflect the vitality and vector potential of ticks. However, an integrated analysis of proteins in tick faeces is lacking. The present study explored the protein components in the faeces of the tick Haemaphysalis flava, by liquid chromatography-tandem mass spectrometry (LC/MS-MS) to identify potential protein antigens for vaccine development against ticks...
