The environmental issue has become a global problem that needs to be examined frequently, motivating researchers investigate it. Thus, the present study investigated asymmetric impact of natural resources, technological innovation, and globalization on ecological footprint in presence Kuznets curve (EKC) Belt Road Initiative (BRI) economies. This research divided BRI economies into high income, middle-income, low-income levels capture income differences. used annual time series data from...

Aquatic organisms such as fish can accumulate high concentrations of arsenic (As), which has toxic effects on fish. However, whether the intestinal flora are involved in As damage to tissues and underlying process unclear. Common carp (Cyprinus carpio) were exposed (2.83 mg/L) water for 30 days, blood, muscle, intestine, intestine samples collected. Intestinal pathological sections observed, lipopolysaccharide (LPS) levels serum accumulation tight junction-related factors measured. The gut...

Instant dark teas (IDTs) were individually liquid-state fermented using the fungi Aspergillus cristatus, niger , and tubingensis . To understand how chemical constituents of IDTs affected by fungi, samples collected measured liquid chromatography-tandem mass-tandem mass spectrometry (LC-MS/MS). Untargeted metabolomics analysis revealed that 1,380 identified in positive negative ion modes, 858 kinds components differential metabolites. Through cluster analysis, different from blank control,...

Abstract This research applies the method of moments quantile regression (MQR) to probe effects formal (market and nonmarket) informal environmental regulations ([ERs] education [EDU] green technology [TEC]) on six components ecological footprint (EF). We investigate whether ERs are feasible tools for lessening degradation by examining ER‐induced Kuznets curve (EKC) hypothesis. Results reveal that nonmarket‐based EKC hypotheses generally supported carbon, fish, forest footprints, signifying...

Microbes are critical for the flavor development of Sichuan South-road Dark Tea (SSDT) during pile-fermentation. However, their mechanism action has not been fully elucidated yet. In this study, SSDT microbial metagenome obtained from different locations piled tea center pile-fermentation metaphase were functionally annotated, and glycoside hydrolase (GH) genes core functional strain comprehensively analyzed. The results revealed that carbohydrate metabolism (8.2%) predominant in total...

Among all types of tea beverage, wine uniquely combines the flavor and wine, its consumption is increasing in recent years. "Ziyan" a new type fermented rich anthocyanins. The information about dynamic changes major chemical volatile components processing scarce. This study aimed to reveal sugar, total acids, catechins, anthocyanins during processing. Results showed that anthocyanin, catechins contents were dramatically decreased, while epigallocatechin gallate retention remained high...

Abstract Jasmine tea is loved by most people who drink flower owing to its unique aroma, and it known as the top of teas. In our study, quantitative evaluation quality jasmine detection aroma components were carried out. First, flavor 92 kinds was evaluated using multiple sub‐factor methods. According results, divided into three types: “fresh lovely” (FL), “heavy thick” (HT), heavy” (FH). Gas chromatography–mass spectrometry (GC–MS) used detect types samples. α‐Farnesene, cis‐3‐hexenyl...

Raw dark tea (RDT) usually needs to be stored for a long time improve its quality under suitable relative humidity (RH). However, the impact of RH on is unclear. In this study, we investigated metabolites and microbial diversity, evaluated sensory RDT three conditions (1%, 57%, 88%). UHPLC-Q-TOF-MS analysis identified 144 metabolites, including catechins, flavonols, phenolic acids, amino organic acids. 57% led higher levels O-methylated catechin derivatives, polymerized flavonols/flavones...

Tea wine is a beverage that combines the flavors of tea and with variety health benefits has thus attracted widespread attention. However, few systematic studies have focused on dark wine, particularly dynamic changes in aroma. A sensory evaluation was conducted based process optimization, headspace solid-phase microextraction combined gas chromatography-mass spectrometry used to analyze volatile components wine. The results showed gradually characteristics as fermentation proceeded,...

Objective To explore the clinical characteristics and surgical treatment outcomes of spinal cord injury without radiographic abnormality (SCIWORA) in children. Methods A retrospective analysis was conducted on data four children diagnosed with SCIWORA who were admitted to Neurosurgery Department Qingdao Women Children's Hospital from November 2022 June 2024. All pediatric patients underwent laminectomy for canal decompression along resection filum terminale. Postoperatively, a regimen...

In this study, the dynamic changes of different anthocyanins in processing 'Ziyan' tea wine were investigated quantitatively. Results showed that six types anthocyanins, namely petunidin, malvidin, pelargonidin, delphinidin, cyanidin and peonidin, as well two co-pigmented substances, procyanidins flavonoids, detected wine. As fermentation proceeded, contents peonidin decreased. Among them, pelargonidin a tendency decreasing first, then increasing finally decreasing, whereas delphinidin...

The fungus Penicillium citrinum (P. citrinum), which is found in Chinese dark tea, involved the production of citrinin (CIT), a secondary metabolite with renal toxicity. In this study, rapid method was used to detect CIT tea samples from different regions and years. Of 216 tested, 5 were detected have contamination, concentration ranging 272.43 ± 16.57 649.68 62.16 μg kg−1. Risk assessment for consuming showed that four heavy intake consumer groups deterministic risk had hazard quotients...

Microbes are critical in the Sichuan South-road Dark Tea (SSDT) organoleptic quality development during pile-fermentation. Piled tea center at fermenting metaphase is crucial for conversion of its components. In this study, we investigated microbial community piled SSDT below stacked surface 15 cm (SSDTB), 50 (SSDTX), and 85 (SSDTH) on second turning time pile-fermentation, respectively. Results showed that SSDTH SSDTB had a higher similarity community. Pantoea (36.8%), Klebsiella (67.7%),...

In recent years, there has been an increasingly heated debate on whether Chinese dark tea is contaminated with mycotoxins and it poses health risks to consumers. this study, a rapid method based high-performance liquid chromatography was used detect ochratoxin A (OTA) in samples from different regions of China years. Of the 228 tested, 21 were detected for OTA contamination, concentration ranging 2.51 ± 0.16 12.62 0.72 μg/kg. Subsequently, drinking risk assessment conducted, hazard quotient...

Mulberry leaves (Morus alba L.) exhibit antidiabetic properties; however, their taste is unappetizing, leading to limited practical applications. Although Fu brick tea has a favorable flavor, its hypoglycemic effects are weak. Hence, we combined the two create mulberry leaf (SF) and investigated sensory perception, safety, microorganism content, key metabolites, impact on hyperglycemic mice using same raw materials techniques prepare (F) (S) individually. Our study showed that SF, which...
