Two grape varieties 'Italia' and 'Centenial seedless' cultured in protected and delayed cultivation were used as experimental materials to study the effects of red and blue light quality on chlorophyll content, net photosynthetic rate, and endogenous hormone content during leaf senescence. The results showed that the chlorophyll content and net photosynthetic rate of the grapes were significantly enhanced in the red light treatment. Although the content of endogenous GA3 was decreased, an increase in abscisic acid (ABA) content and a decrease of total content of zeaxanthin (ZR) were obviously slowed, which led to the significant increase in value of (GA3 +ZR)/ABA, delaying leaf senescence...

Non-invasive microsensing technique has been widely used in evaluating the adaptive responses of plant cells and tissues to abiotic stresses. One of the representative techniques is the microelectrode ion flux estimation (MIFE), which allows concurrent quantification of net fluxes with high spatial and temporal resolution. More importantly, this technique permits simultaneous recording of ion concentration and mobility with less intervention to the in situ physiological status. With the availability of such advanced technique, the last three decades have seen a significant progress towards the role of ion signaling in a variety of abiotic stresses including salinity, extreme temperature, osmotic stress, hypoxia, and drought...

Among their responses to microbial infection, plants deploy an arsenal of natural antibiotic products. These historically have been identified on the basis of their antibiotic activity in vitro, which leaves open the question of their relevance to defense in planta. The vast majority of such natural products from the important crop plant rice (Oryza sativa) are diterpenoids whose biosynthesis proceeds via either ent- or syn- copalyl diphosphate (CPP) intermediates, and which were isolated on the basis of their antibiotic activity against the fungal blast pathogen Magnaporthe oryzae...

Glutamine is the most abundant amino acid found in plasma and cells. It is the preferred fuel for enterocytes in the small intestine, macrophages, and lymphocytes. After serious burn, increased requirement of glutamine by the gastrointestinal tract, kidney and lymphocytes, and relatively insufficient self synthesis likely contribute to the rapid decline of glutamine in circulation and cells. Glutamine supplementation can not only protect intestinal mucosa, maintain normal intestinal barrier function, reduce bacterial translocation, and enhance the intestinal immune function, but also increase the number of lymphocytes, enhance the phagocytic function of macrophage, promote the synthesis of immunoglobulin, and reduce the body's inflammatory response, so as to enhance the immune function...

Nevrorthidae is a family of Neuroptera with low species diversity, disjunct geographic distributions, and a controversial phylogenetic status. Previous fossil records of the family are from the Eocene except for the recently described species Cretarophalis patrickmuelleri Wichard, 2017 from mid-Cretaceous Burmese amber, following earlier records of an undescribed species. However, such a significant finding of this family from Mesozoic was originally presented only with a preliminary description. Here we re-describe the species based on exquisitely preserved materials from mid-Cretaceous Burmese amber that provides for a much more detailed description, in particular of the hindwing, female genitalia, and larval head...

Toll-like receptor (TLR) 2 is a key regulator of innate immune responses and has been shown to play an important role in inflammation-associated cancers. In this study, we aimed to evaluate the role of TLR2 in colorectal cancer (CRC). We demonstrated that TLR2 mRNA and protein expression was significantly upregulated in tumors from CRC patients and indicated poor prognosis. Using the TLR2 agonist Pam3Cys (P3C) to activate TLR2 signaling in human CRC cell lines, we showed that TLR2 drives cellular proliferation, which was dependent upon PI3K/Akt and NF-κB signaling pathways and was associated with the upregulation of anti-apoptotic genes BCL2A1, WISP1 and BIRC3...

We have developed a mild and scalable catalyst-free [3 + 2] cyclization of dihydroisoquinolines and isatin-derived Morita-Baylis-Hillman carbonates. The incorporation of tetrahydroisoquinoline and spirooxindole frameworks could be realized affording highly functionalized heterocycles in moderate to excellent yields with good diastereocontrols (up to 92% yields, >20 : 1 dr). The extension of this method to dihydro-β-carbolines has also been achieved. A gram-scale reaction could be performed successfully enabling the potential application for further biomedical research...

We report a facile transfer method to fabricate flexible photodetectors directly on tape, wherein the films formed by different processes were integrated together. The tape-based photodetectors with CdS nanowire (NWs) active layers exhibited good performances as those fabricated by conventional processes. The obvious persistent photocurrent (PPC) in our device was eliminated by introducing a conductive polymer poly (3, 4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) onto the CdS NWs layer. By adjusting the concentration of the PEDOT:PSS aqueous solution, a device with a fast response, ultrashort decay time, and relatively large photocurrent was obtained...

OBJECTIVE: Thoracic aortic dissection (TAD) is a serious condition requiring urgent treatment to avoid catastrophic consequences. The inflammatory response is involved in the occurrence and development of TAD, possibly potentiated by platelet-derived growth factors (PDGFs). This study aimed to determine whether expression of PDGF-B (a subunit of PDGF-BB) was increased in TAD patients and to explore the factors responsible for its upregulation and subsequent effects on TAD. METHODS: Full-thickness ascending aorta wall specimens from TAD patients (n = 15) and control patients (n = 10) were examined for expression of PDGF-B and its receptor (PDGFRB) and in terms of morphology, inflammation, and fibrosis...

BACKGROUND: Extensive modification of genome is an efficient manner to regulate the metabolic network for producing target metabolites or non-native products using Corynebacterium glutamicum as a cell factory. Genome editing approaches by means of homologous recombination and counter-selection markers are laborious and time consuming due to multiple round manipulations and low editing efficiencies. The current two-plasmid-based CRISPR-Cas9 editing methods generate false positives due to the potential instability of Cas9 on the plasmid, and require a high transformation efficiency for co-occurrence of two plasmids transformation...
