Abstract:
... Herein, a novel direct Z-scheme photocatalyst was accomplished by hybridization of 0D MoS₂ quantum dots (MSQDs) and 3D honeycomb-like conjugated triazine polymers (CTP) (namely, CTP-MSQD). The unique 0D/3D hierarchical structure significantly enhanced the exposure of active sites and light harvesting property, while the formed p-n junction enabled the direct strong interface coupling without the n ...

Currently, the development of sensitive and visual strategy for Cry1Ab detection, particularly using a switchable dual-mode detection system based on a single component, remains a great challenge. Here, a photoelectrochemical (PEC) and visual dual-mode sensor was designed for Cry1Ab detection based on a proximity hybridization driven multifunctional probe. In the presence of Cry1Ab, specific desor ...

Abstract:
... In this study, the dual signal-labeled hairpin-structured DNA (dhDNA)-based probes have been developed to construct a novel nano-biosensor. This one hairpin-structured probe consists of a thiolated methylene blue-labeled hairpin capture probe (MB-HCP) as an inner reference probe and a ferrocene-modified anti-miRNA-21 DNA probe (Fc-AP-21). This novel integrated structure of MB-HCP and Fc-AP-21 was ...

Abstract:
... Urotensin II (UII) is a kind of fish somatostatins cyclic peptide, which was originally extracted from the caudal neurosecretory system (CNSS). The system of UII and UII receptor (UIIR) has been reported to have multiple physiological regulatory functions, such as cardiovascular control, osmoregulation, and lipid metabolism. However, the effect of UII and UIIR on the ovarian development has not be ...
... On-site screening of biotoxins is of great importance for food safety. A new electrochemical-biosensing strategy was constructed for ochratoxin A (OTA) detection by direct using ready-made commercial portable-glucose-meter (PGM). Aptamer against OTA was adopted as the recognition probe and pre-immobilized onto the sensing interface. The complementary biotin-modified probe was further decorated by ...
... The hypoxic tumor microenvironment and photodynamic therapy (PDT)-aggravated hypoxia compromise the anticancer efficacy of chemotherapy, immunotherapy, and PDT. Thus, sophisticated nanomedicines that can activate their anticancer capability in situ in response to specific stimuli need to be developed. This study aimed to construct a hybrid nanomedicine that activated chemotherapy by inducing hypox ...
... Bananas (Musa spp.) are an important source of pro-vitamin A, derived from carotenoids. Some cultivated bananas originated from intra-specific hybridization resulting in genotypes which are diploid (AA) and triploid (AAA) genomes that are the most important bananas for desserts. The accumulation of carotenoids and transcripts of genes related to carotenoid biosynthesis during fruit development and ...
... The correlation of antioxidant activity and prebiotic effect about oat phenolic compounds was invested, while there exists limited studies. Free and bound phenolic compounds were separated from ethyl acetate, n-butanol and aqueous fractions. Fluorescence in situ hybridization was used to investigate gut microbiota of in vitro fermentation samples. The results showed that ethyl acetate fraction pos ...

Abstract:
... Hybridization is a widely used and effective method in grouper breeding. In this study, we constructed full-sib families of brown-marbled grouper (Epinephelus fuscoguttatus), Jinhu grouper (E. fuscoguttatus ♀ × E. tukula ♂), and Hulong grouper (E. fuscoguttatus ♀ × E. lanceolatus ♂) and compared the growth characteristics under industrial conditions. The body weight of Jinhu grouper was 1.49 times ...

The complete Mylopharyngodon piceus insulin (Mp-Ins) gene is 1,965 bp long and includes a 1,499 bp 5ʹ-untranslated region (UTR), a 139 bp 3′-UTR with a poly(A) tail, and an open reading frame (ORF) of 327 bp. The predicted molecular weight of the recombinant Mp-Ins(rMp-Ins) protein is 11.87 kDa. The mRNA e ...

Abstract:
... Tilapia is the second most prolific species grown in aquaculture after carp, and is widely grown in >100 countries. Myostatin (MSTN) has been proved to be a negative regulator of skeletal muscle growth. Mutation of MSTN gene resulted in significant increase in both body size and muscle mass in vertebrates, mostly with a species-specific effect. To generate a new strain in Nile tilapia (Oreochromis ...

Abstract:
... Construction of complex DNA circuits is difficult due to unintended hybridization and degradation by enzymes under biological conditions. We herein report a hybridization chain reaction (HCR) circuit composed of left-handed acyclic d-threoninol nucleic acid (d-aTNA), which is orthogonal to right-handed DNA and RNA. Because of its high thermal stability, use of an aTNA hairpin with a short 7 base-p ...

... Stacked heterointerfaces of two-dimensional (2D) materials are well-suited to obtain novel electronic functionality at small length scales, because the intrinsic properties of both materials can be blended by interlayer coupling with remarkable effects on the electronic band structure. In particular, band degeneracy at the K and [Formula: see text] Brillouin zone valleys of 2D materials can be bro ...
... In the 18th and 19th centuries the Eurasian Collared Dove Streptopelia decaocto was widely considered to be the wild ancestor of the domesticated Barbary Dove (domestic S. risoria), and even following its recognition as a species its taxonomic status was a source of confusion. Since 1900, and the species' massive geographic expansion (both naturally and by introduction) the two taxa have occasiona ...
