Abstract Environmental pollution threatens human health and ecosystem sustainability, boosting a huge demand for filters. However, the petroleum‐based filters are likewise environmentally hazardous since their non‐degradability results in disposal landfills. Although biodegradable synthetic polymers have been contemplated as alternative filtration materials, utilization fabricating ultrafine fibers to construct effective 3D remains an obstacle. In this study, all‐biomass nanofibrous...

The hemolymph-like HL3 saline () and standard are two widely used bathing solutions for physiological recordings at the Drosophila larval neuromuscular junction. It has been established that longevity of preparations is better maintained in saline. However, can produce results inconsistent with previous findings saline, particularly on temperature sensitivity membrane excitability phenotypes. In wild-type larvae, excitatory junctional potentials (EJPs) (containing 4 mM Mg2+ 1.8 Ca2+) were...

Although regenerated silk fibroin (SF), which has excellent biocompatibility, biodegradability, and a low inflammatory response in vivo, promising applications tissue engineering, the mechanical properties biofunctionality must be further improved to satisfy tissue-engineering applications. Cellulose nanofibrils (CNFs) are candidates for bionanocomposite production due their ultrahigh strength biocompatibility. In this study, CNFs were extracted directly from microcrystalline cellulose using...

Hydrogels with a combination of mechanical flexibility and good electrical conductivity hold significant potential for various applications. Nonetheless, it is inevitable that water-based conductive hydrogels lose their elasticity at extremely low temperatures, severely limiting utilization in ultralow temperature environments, such as those Arctic/Antarctic exploration. In this study, we developed hydrogel based on double network cross-linking strategy incorporated silk fibroin (SF)...

Renal cell carcinoma (RCC) is one of the most common kidney cancers worldwide. Although great progressions have been made in past decades, its morbidity and lethality remain increasing. Long noncoding RNAs (lncRNAs) are demonstrated to play significant roles tumorigenesis. This study aimed investigate detailed lncRNA FTX RCC proliferation metastasis. Our results showed that transcript levels both clinical tissues cultured cells were significantly upregulated associated with multiple...

A major challenge for the silk textile industry and process of silk-based biomaterials is to find a degumming method that can completely remove sericin while avoiding obvious hydrolysis damage fibroin. In this study, papain was used degum Bombyx mori fibers under nearly neutral conditions based on specificity sericin. The efficiency investigated, as well mechanical properties molecular weight sericin-free results indicated increasing concentration aided in removal, increased 3.0 g/L,...

Abstract Adsorptive separation of propyne/propylene (C 3 H 4 /C 6 ) is a crucial yet complex process, however, it remains great difficulty in developing porous materials that can meet the requirements for practical applications, particularly with an exceptional ability to bind and store trace amounts C . Functionalization pore‐partitioned metal–organic frameworks ( ppMOFs methodically suited this challenge owing possibility dramatically increasing binding sites on highly confined domains. We...

Abstract It remains a great challenge to fabricate physically cross‐linked silk fibroin (SF) hydrogels with rapid gelation and robust mechanical properties. In this study, novel SF hydrogel is obtained by synergistically modulating the molecular weight (MW) freeze‐inducing process, avoiding use of any exterior additives. First, effects MW on self‐assembly behaviors are investigated under physiological temperature. The results demonstrate that high derived from papain degumming (PSF)...

Abstract Silicon plays a vital role in plant growth. However, molecular mechanisms response to silicon have not previously been studied wheat. In this study, we used RNA-seq technology identify differentially expressed genes (DEGs) wheat seedlings treated with silicon. Results showed that many responded treatment, including 3057 DEGs, of which 6.25% (191/3057) were predicted transcription factors (TFs). Approximately 14.67% (28 out 191) the TFs belonged MYB TF family. Gene ontology (GO)...

Foxtail millet (Setaria italica) is a monotypic species widely planted in China. However, residual atrazine, commonly used maize herbicide, soil, major abiotic stress to millet. Here, we investigated atrazine tolerance based on the field experiments, then obtained an atrazine-resistant variety (Gongai2, GA2) and atrazine-sensitive (Longgu31, LG31). To examine effects of genes metabolites plants, compared transcriptomic metabolomic profiles between GA2 LG31 seedling leaves. The results showed...
