A couple of primers was designed on the base of VP2 gene sequence of infectious bursal disease virus (IBDV) HZ2 strain, and the VP2 gene was successfully cloned into eukaryotic expression vector pDsRed2-N1. Then, the recombinant plasmid pDsRed2-N1-VP2 was constructed. The 279 site and 284 site on VP...

The exploration of asteroids has received increasing attention since the 1990s because of the unique information these objects contain about the history of the early solar system. Quasi-satellites are a population of asteroids that co-orbit closely with, but are outside the gravitational control of,...

An electronic nose (e-nose, PEN 2) was employed to classify the pork groups with different storage times (0-6 d). To acquire the optimum experimental procedure, the method of analysis of variance (ANOVA) was adopted. The results showed that the mass of the pork samples affected highly significantly...

In order to improve the immunity effect of infectious bursal disease virus (IBDV) polyprotein (VP2/4/3) DNA vaccine, fusion genes of IBDV polyprotein (VP2/4/3) gene and chicken interleukin 18 (ChIL-18) gene were constructed using the technique of splicing by overlapping extension (SOEing) and three...

According to the air and soil temperature requirement of crops at seedling stage, a new underground heat storage system to be used in greenhouse was designed. As a key factor of heat exchange, distribution of airflow velocity in the heat exchange pipes was measured. The results indicated that air fl...

In order to establish the reverse genetics of IBDV, the sequences of T 7 promoter and ribozyme HDV were introduced into the 5 and 3 terminals of segments A and B of IBDV genome using PCR. Then the segments, which containing promoter and ribozyme HDV sequences, were cloned into PT-Pluc vector and nam...

We report a passively Q-switched self-Raman laser using a dual-end composite c-cut Nd:YVO₄ crystal, which generates switchable visible emissions at 533 nm, 560 nm, and 589 nm. A Cr⁴⁺:YAG/YAG composite crystal served the role of a saturable absorber to ac...

The escalating industrial emissions have dramatically increased airborne particulate matter (PM), particularly submicron particles (PM0.3), creating substantial health risks through respiratory system penetration. Current fiber-based filtration systems predominantly relying on electrostatic adsorpti...

Theories and experiments have shown that physical exercise can improve mental resilience and resist the negative effects of psychological stress. Neurodegenerative diseases are a collection of diseases in which progressive changes in the structure and function of neurons result in progressive disord...

This study was conducted to determine the effect of different forms of yeasts Saccharomyces cerevisiae supplementation on serum antioxidant capacity, mucosal secretory immunoglobulin A (sIgA) secretions and gut microbial populations in weaned piglets. A total of 96 piglets weaned at 14 d of age were...

A visible-light-induced brominated spirocyclization of N-arylpropiolamides and CBr4 for the synthesis of 3-bromo-azaspiro[4,5]trienones is reported here. This process allows the formation of C–Br, C–C, and C=O bonds in a single reaction via a cascade radical addition/ipso-cyclization/oxidative dearo...

The Sun is the primary energy source driving the Earth's climate system. A prevailing hypothesis suggests that even minor variations in solar activity, when amplified by climate system feedback mechanisms, can induce significant climatic changes on decadal to centennial timescales. However, the...

Abstract Metal–organic frameworks (MOFs) represent a novel electrochromic material system but are limited in tunable color versatility, rapid switching speed, and long‐term cycling stability. A new multicolor electrochromic behavior is reported, with transitions from green to blue to purple, in cond...

Abstract Prenatal environmental stress damages fetal testicular development, leading to male infertility. However, the precise mechanisms underlying the impact of gestational environmental stress on fetal testicular development require further investigation. This study demonstrates that gestational...
