This present study aims to develop a visible-light driven photocatalytic dual layer hollow fiber (DLHF) membrane for photodegradation activity. Nitrogen-doped TiO2 DLHF membranes with different loadings of N-doped TiO2 were successfully fabricated via a single step co-extrusion method. The fabri...

Ilmenite is natural mineral ore made up with titanium and iron mineral; including small portion of magnesium and manganese. To the best of our knowledge, photo-degradation of Reactive Black 5 dye (RB 5) using ilmenite under solar irradiation is still lacking. In the present study, the physicoche...

In Saccharomyces uvarum cultures, subinhibitory doses of amphotericin B and desertomycin induced alterations in the plasma membrane phospholipid composition. Amphotericin B increased the lipid content in the plasma membrane. It showed a pronounced effect on fatty acyl constituents by raising the...

Alumina microfibers were prepared and used to construct an electrochemical sensor for simultaneous detection of ponceau 4R and tartrazine. In pH 3.6 acetate buffer, two oxidation waves at 0.67 and 1.01 V were observed. Due to porous structures and large surface area, alumina microfibers exhibite...

In the present work, a novel strategy based on new carbon nanotube (CNT) and polypyrrole (ppy) composite modified electrode for the simultaneous determination of the isomers of Amaranth (E123) and Ponceau 4R (E124) was proposed. Due to the increasing dispersibility and effective surface area of ...

Pidotimod® is a dipeptide with widely recognized immunomodulatory properties and with particularly beneficial effects for the treatment of acute respiratory and urinary tract infections. Pidotimod® presents two chiral centres which originate four stereoisomers. (4R,2′S, 4S,2′R, 4R,2′R and 4S,...

A sensitive and convenient electrochemical method was developed for the simultaneous determination of the isomers of Ponceau 4R and Amaranth by an expanded graphite paste electrode (EGPE). The EGPE was prepared by mixing EG with solid paraffin. Compared with flake graphite paste and carbon paste...

It is quite important to research rapid and sensitive analytical method for ponceau 4R due to its adverse health effects. In this work, a kind of copper-based metal-organic frameworks were prepared using 1,3,5-Benzenetricarboxylic acid (H3BTC) as the ligand, and then used to construct a novel el...

Novel integrated chromatographic methods need to be developed for specific, low-cost protein purification from raw materials. Here, a process for bovine lactoferrin (Lf) isolation from sweet whey was developed using cross-linked chitosan mini-spheres with immobilised Yellow HE-4R dye as a low-co...

BackgroundThe prognostic value of circulating polyunsaturated fatty acid (PUFA) levels is unclear.

Palytoxin (PTX) has been widely studied owing to its outstanding toxic properties and complex structural features. It is a great challenge to identify and isolate analogues of PTX from various organisms and reveal their physiological activities. We previously reported the isolation of PTX as an ...

ABSTRACTDairy products are important sources of nutrients for human health and in recent years their consumption has increased worldwide. Therefore, the food industry is interested in applying analytical technologies that are more rapid and cost-effective than traditional laboratory analyses. In...

A near infrared spectroscopy (NIRS) method was used for rapid quality evaluation of ferulic acid content in chrysanthemum morifolium cv. (Chuju) continuous cropping soil. Standard leverage, studentized residual and Mahalanobis distance were calculated to eliminate abnormal samples. After the ini...

Following growth declines and increased mortality linked to acid deposition-induced calcium depletion, red spruce (Picea rubens Sarg.) in the northeastern United States are experiencing a recovery. We found that more than 75% of red spruce trees and 90% of the plots examined in this study exhibi...

Good management of sulfide minerals and sulfuric acid in Acid Sulfate Soils (ASS) requires cost-effective rapid analytical data for their characterisation. However, the determination of properties in ASS samples using traditional laboratory techniques is expensive and time consuming. Excessive d...

ResumenIntroducción y objetivoExiste controversia sobre el riesgo/beneficio de anticoagular/antiagregar a pacientes con enfermedad renal crónica (ERC). Analizamos el impacto de la anticoagulación/antiagregación en pacientes con ERC sobre el riesgo hemorrágico, cardiovascular y la mortalidad.

BackgroundAlthough vertical banded gastroplasty (VBG) was endorsed by the 1991 National Institutes of Health Consensus Conference for the treatment of morbid obesity, it has largely been abandoned owing to the poor long-term weight loss and band-related complications. The objective of the presen...

ABSTRACTDomestic yaks (Bos grunniens) and domestic Taurus cattle (Bos taurus) are closely related. An interesting phenomenon in interspecific crossings is male sterility in the F1 hybrid (yattle) and F2 backcross, with no late meiotic cells or spermatids in the seminiferous tubules. The mammalia...

ObjectivesThe use of Y-grafts for Fontan completion is hypothesized to offer more balanced hepatic flow distribution (HFD) and decreased energy losses. The purpose of this study is to evaluate the hemodynamic performance of Y-grafts over time using serial cardiac magnetic resonance (CMR) data an...

In this work, the hierarchical Y zeolites are firstly obtained by etching NaY zeolites with different NH4HF2 solutions. The morphology and microstructure, toluene adsorption property of as-prepared hierarchical Y zeolites are characterized. The results demonstrate that the mesoporous number and ...
