Effect of partial substitution of complex phosphates with sodium bicarbonate on aggregation, conformation and gel properties of beef-pork-chicken complex myofibrillar proteins.

Background: Complex phosphates (CP) can improve the physicochemical properties and gelation properties of myofibrillar fibrous protein (MP) in mixed meat products, but an excessive intake of phosphates over a long period of time is harmful to health. The present study investigated the effects of partial or complete substitution of CP with sodium bicarbonate (SB) on the physicochemical properties and gel properties of beef-pork-chicken mixed myofibrillar protein (BPC-MP), aiming to evaluate the feasibility of this method in reducing the amount of phosphate in mixed meat products.

Results: Under the optimal substitution conditions, the turbidity of BPC-MP was reduced by 37.

KLK4 Silencing Inhibits the Growth of Chromophobe Renal Cell Carcinoma through ERK/AKT Signaling Pathway.

Introduction: Renal cell carcinoma (RCC) generally has a poor prognosis because of late diagnosis and metastasis. Despite its abundance in RCC cells, the functions of kallikrein-related peptidase 4 (KLK4) in RCC cells remain unknown. The results of this investigation were examined to discover if KLK4 gene silencing influences the development of RCC cells.

Unbalanced emission reductions and adverse meteorological conditions facilitate the formation of secondary pollutants during the COVID-19 lockdown in Beijing.

During the coronavirus disease 2019 (COVID-19) lockdown in 2020, severe haze pollution occurred in the North China Plain despite the significant reduction in anthropogenic emissions, providing a natural experiment to explore the response of haze pollution to the reduction of human activities. Here, we study the characteristics and causes of haze pollution during the COVID-19 outbreak based on comprehensive field measurements in Beijing during January and February 2020. After excluding the Spring Festival period affected by fireworks activities, we found the ozone concentrations and the proportion of sulfate and nitrate in PM increased during the COVID-19 lockdown compared with the period before the lockdown, and sulfate played a more important role.

Synergistic Effects of a CeO/SmMnO-H Diesel Oxidation Catalyst Induced by Acid-Selective Dissolution Drive the Catalytic Oxidation Reaction.

A diesel oxidation catalyst (DOC) is installed upstream of an exhaust after-treatment line to remove CO and hydrocarbons and generate NO. The catalyst should possess both good oxidation ability and thermal stability because it sits after the engine. We present a novel high-performance DOC with high steam resistance and thermal stability.

Preparation and properties of chitosan-based bacteriostatic agents and their application in strawberry bacteriostatic preservation.

The purpose of this study is to develop a green and safe chitosan-based preservative which can be applied in strawberry preservation. Chitosan (CS) was treated by 2,2,6,6-tetramethylpiperidine oxygen radical/laccase oxidation system (TEMPO/laccase oxidation system), which was mainly used to prepare TEMPO/laccase chitosan (TLCS). Furthermore, on this basis, the structure and performance of TLCS were also studied.

Spatial-temporal dynamics, ecological risk assessment, source identification and interactions with internal nutrients release of heavy metals in surface sediments from a large Chinese shallow lake.

The surface sediment concentrations of heavy metals (Cu, Zn, Pb, Cd, Cr, Hg, and As), major metals (Fe and Mn), and the nutrient concentrations in the interstitial water of Lake Houguan, a large eutrophic shallow lake, were surveyed for three years. The results showed that Cu, Zn, and Fe were significantly higher in the east lake parts, and Cd in November was significantly higher than April. 19% of Hg and all of As were larger than the probable effect concentrations (PECs) according to the consensus-based sediment quality guidelines (SQGs), and the geo-accumulation index (I) indicated As, Hg, and Cd were slightly polluted to severely polluted.

Selenium uptake and simultaneous catalysis of sulfite oxidation in ammonia-based desulfurization.

Accelerating the (NH)SO oxidation gives rise to the reclaiming of byproduct, while there are secondary environmental risks from reduction of the coexisted selenium species by sulfite. In this study, a bi-functional Co-SBA-15-SH, were synthesized through Co impregnation and sulfhydryl (-SH) decoration, which can simultaneously uptake Se and accelerate sulfite oxidation efficiently. Meanwhile, the adsorption kinetics and migration mechanism of Se species were revealed through characterization and density functional calculations, with maximum adsorption capacity of 223 mg/g.

Clinical analysis of everolimus in the treatment of metastatic renal cell carcinoma.

Background: Renal cell carcinoma (RCC) is the most common type of kidney cancer, and accounts for approximately 3% of all malignancies. Metastatic RCC (mRCC) is not sensitive to traditional radiotherapy and chemotherapy, therefore targeted therapy has become an important treatment option. In this study, the second-line targeted drug everolimus (Afinitor), a mammalian target of rapamycin (mTOR) inhibitor, was investigated for its clinical efficacy and adverse events in mRCC after failure of first-line targeted therapy, such as sorafenib, sunitinib or pazopanib.

Quenched g_{A} in Nuclei and Emergent Scale Symmetry in Baryonic Matter.

The recent RIKEN experiment on the quenched g_{A} in the superallowed Gamow-Teller transition from ^{100}Sn indicates the role of scale anomaly encoded in the anomalous dimension β^{'} of the gluonic stress tensor Tr G_{μν}^{2}. This observation provides support to the notion of hidden scale symmetry emerging by strong nuclear correlations with an infrared (IR) fixed point realized-in the chiral limit-in the Nambu-Goldstone mode. We suggest there is an analogy in the way scale symmetry manifests in a nuclear medium to the continuity from the unitarity limit at low density (in light nuclei) to the dilaton limit at high density (in compact stars).
