Changes in key odorants and aroma profiles of three types green tea during storage after baking treatment were determined using headspace solid-phase microextraction–gas chromatography–mass spectrometry/olfactometry, odor activity value (OAV) orthogonal partial least-squares discriminant analysis. As the stale developed storage, content aldehydes decreased, whereas contents ketones heterocycles (furans, pyrroles, etc.) increased. Key odorants, including (E,E)-2,4-heptadienal, α-terpineol,...
This paper applies near-infrared spectroscopy (NIRS) and multiple chemometrics to efficiently distinguish the origins of fresh tea leaves. The key components were obtained using partial least squares discriminant analysis (PLS-DA) method. PLS, synergy interval PLS (siPLS), principal component (PCA), genetic algorithm (GA), their combination methods used establish NIRS non-destructive discrimination models. Then, practical application was examined external samples. study identified nine...
Tea plant (Camellia sinensis) has strong enrichment ability for selenium (Se). Selenite is the main form of Se absorbed and utilized by tea plant. However, mechanism selenite absorption accumulation in still unknown. In this study, RNA sequencing (RNA-seq) was used to perform transcriptomic analysis on molecular 397.98 million high-quality reads were obtained assembled into 168,212 unigenes, 89,605 which extensively annotated. There 60,582 1,362 differentially expressed genes (DEGs) roots...
Fresh leaves of Echa 1 were fixed by roller, steam/hot air and light-wave, the effects three fixation methods on chemical characteristics straight-shaped green teas (GTs) studied widely targeted metabolomic analysis. 1001 non-volatile substances was identified, from which 97 differential metabolites selected criteria variable importance in projection (VIP) > 1, p < 0.05, |log2(fold change)| 1. Correlation analysis indicated that 14 taste-active major contributors to taste differences between...
Steamed green tea has unique characteristics that differ from other teas. However, the alteration patterns of non-volatile metabolites during steamed processing are not fully understood. In this study, a widely targeted metabolomic method was employed to explore changes in processing. A total 735 compounds were identified, covering 14 subclasses. Of these, 256 showed significant at least one step. Most amino acids, main catechins, caffeine, and sugars excluded analysis. The most alterations...
Background: Roasting conditions significantly influence the sensory profile of Hubei strip-shaped green tea (HSSGT). Methods: This study examined effects roast processing on attributes, color qualities, physicochemical properties, and key aroma compounds HSSGT. Sensory evaluation, qualities determination, principal component analysis components (PCA), HS-SPME (headspace solid-phase microextraction) coupled with GC-MS (gas chromatography–mass spectrometry), relative odor activity value...
This study aimed to compare the effect of hot roller (HR) drying and air (HA) on sensory evaluation, chemical quality, antioxidant activity, metabolic profile Yihong Congou black tea processed from E'cha NO1. The dried with HA obtained higher scores better qualities such as hue brew color (a b), content theaflavins, thearubigins, water extract, free amino acids, polyphenol, ratio polyphenol acids well capacities compared that HR. increased contents volatile compounds had positive correlation...
The recent outbreak of novel coronavirus-infected pneumonia (NCIP) in China (1) has attracted much attention domestically and internationally.As the occurred, carried out emergency responses quickly, notified World Health Organization (WHO) a timely manner, shared viral gene sequence with international communities immediately after pathogenic identification.The release information on coronavirus (2019-nCoV), joint research relevant genome mutations, pathogenicity, transmission mechanisms,...
Harvesting seasons are crucial for the physicochemical qualities of large-leaf-variety black tea. To investigate effect harvesting on qualities, color and sensory characteristics tea produced from "Yinghong 9" (Yh) its mutant "Huangyu" (Hy) leaves were analyzed. The results demonstrated that Hy had better chemical characteristics, average, such as a higher content polyphenols, free amino acids, caffeine, galloylated catechins (GaCs) non-galloylated (NGaCs), while hue brew (ΔE*ab Δb*)...
Streptococcus suis ( S. ) is a highly virulent zoonotic pathogen and causes severe economic losses to the swine industry worldwide. Public health security also threatened by rapidly growing antimicrobial resistance in . Therefore, there an urgent need develop new safe antibacterial alternatives against The green tea polyphenol epigallocatechin gallate (EGCG) with number of potential benefits known for its effect; however, mechanism bactericidal action remains unclear. In present, EGCG at...
Abstract In our prior investigation, we discerned loss-of-function variants within the gene encoding glutamine-rich protein 2 (QRICH2) in two consanguineous families, leading to various morphological abnormalities sperm flagella and male infertility. The Qrich2 knockout (KO) mice also exhibits multiple of (MMAF) phenotype with a significantly decreased motility. However, how ORICH2 regulates formation remains unclear. Abnormal glutamylation levels tubulin cause dysplastic microtubules...
Roasting is crucial for producing Yuan An yellow tea (YAYT) as it substantially affects sensory quality. However, the effect of roasting time on YAYT flavor quality not clear. To investigate qualities, chemical components, odor profiles, and metabolic profile YAYTs produced with 13 min roasting, 16 19 22 25 were determined. The roasted got higher scores better such content gallocatechin (GC), gallate (GCG), free amino acids, solutable sugar, meanwhile lightness decreased, hue brew color (b)...
Leishmaniasis is a worldwide but neglected disease of humans and animal transmitted by sand flies, vectors that also transmit other important diseases. Mitochondrial genomes contain abundant information for population genetic phylogenetic studies, in management. However, the available mitochondrial sequences these crucial are limited, emphasizing need developing more markers. The complete genome Phlebotomus chinensis was amplified eight fragments sequenced using primer walking. papatasi...
Abstract The cryopreservation and transplantation of ovarian tissue underscore its paramount importance in safeguarding reproductive capacity ameliorating disorders. However, challenges persist (OTC-T), including the risk damage dysfunction. Consequently, there has been a compelling exploration into realm nanoregulators to refine enhance these procedures. This review embarks on meticulous examination intricate anatomical structure ovary microenvironment, thereby establishing robust...
In order to analyze the changes in microbial community structure during pile fermentation of Qingzhuan tea and their correlation with formation quality compounds tea, this study carried out metagenomic metabolomic analyses samples process tea. The expression abundance microorganisms were investigated through assays. During processing there is a transition from bacterial dominated ecosystem an enriched fungi. metagenomics metabolomics showed that amino acids polyphenol metabolites relatively...
In this study, near-infrared spectroscopy (NIRS) combined with a variety of chemometrics methods was used to establish fast and non-destructive prediction model for the purchase price fresh tea leaves.

Further, there good linear relationship between QI, grades, determination coefficient being greater than 0.99. Then, original spectra samples were obtained...
Trophoblastic neoplasms involving the ovary are uncommon and include gestational tumors, which either metastatic from uterus or ectopic nongestational those of germ cell type/origin somatic tumors with trophoblastic differentiation; in all these types, most pure choriocarcinoma. Intermediate placental site tumor (PSTT) epithelioid (ETT), rare ovary, assumed to be gestational; this is only category formally recognized 2014 World Health Organization (WHO) classification, likely due few...
Usutu virus (USUV) is a mosquito-born flavivirus that can infect multiple avian and mammalian species. The viral surface envelope (E) protein functions to initiate the infection by recognizing cellular receptors mediating subsequent membrane fusion, therefore key virulence factor involved in pathogenesis of USUV. structural features USUV-E, however, remains un-investigated thus far. Using crystallographic method, we determined structure USUV-E pre-fusion state at 2.0 angstrom. As expected,...
