Characterization of the Flavors and Organoleptic Attributes of Petit Manseng Noble Rot Wines from the Eastern Foothills of Helan Mountain in Ningxia, China.

To investigate the effect of infection severity on the flavor characteristics of Petit Manseng noble rot wine, this study analyzed wines produced from Petit Manseng grapes grown in the eastern foothills of Helan Mountain, Ningxia, China. The grapes were categorized into three groups based on infection status: uninfected, mildly infected, and severely infected with . Headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry (HS-SPME-GC-MS) and an electronic nose were employed to detect and analyze the aroma components of wines under the three infection conditions.

Comparison on biological communities between karst and non-karst forests in Yachang, Guangxi.

We investigated the communities of woody plants, ground-dwelling insects, soil bacteria, and soil fungi in both karst and non-karst forests within the Yachang Orchids Natural Reserve, Guangxi, to explore the role of plant communities, stand structure, soil and litter properties in driving the differences in biological community composition. The results revealed that species richness, Shannon index, and Simpson index of plants were significantly higher in karst forest than non-karst forest. There were no significant differences in the species richness or Shannon index of ground-dwelling insects, bacteria, and fungi between the two forest types.

Noise identification of confined orifice flow from sparse experimental data using a pressure decomposition framework.

The present study proposes a pressure decomposition framework designed to decouple hydrodynamic and acoustic components from sparse acoustic measurement data, effectively identifying the flow-induced noise of a confined orifice in lithography. The framework involves three primary steps: peak detection, mode decomposition, and component identification. By employing spectral analysis and spectral proper orthogonal decomposition, the framework extracts key information on discrete tonal frequencies, amplitudes, and waveforms, reconstructing coupled hydrodynamic and acoustic pressures into new modal representations.

Organic matter accumulation under the Middle-Upper Ordovician tectonic transition on the western margin of the North China platform.

The tectonic of the Middle and Late Ordovician in the western margin of the north China Platform is complex, and the accumulation models of organic matter of the Wulalike Formation formed during this period are still unclear. Total organic carbon (TOC) content, mineral composition, organic carbon isotope composition, as well as the major and trace elements in the shale samples were all measured in this study. The Wulalike Formation was formed during a tectonic transition from a passive continental margin to an active continental margin.

Visible-Light-Driven -Selective Heteroarylation of -Fluoroalkyl Hydroxylamine Reagents with Quinoxalin-2(1)-ones.

Herein, we disclose a direct and powerful strategy for the synthesis of highly valuable α-trifluoromethylamine and -trifluoroethylamine derivatives from a visible-light-promoted -selective heteroarylation of -trifluoroethyl hydroxylamine reagents with quinoxalin-2(1)-ones under ambient conditions. The chemoselectivity of the process (trifluoroalkylation or -trifluoroethylamination) can easily be dictated and modulated by a selection of -trifluoroethyl hydroxylamine substrates. The key to success is the protecting group on the N atom of hydroxylamine reagents, which can control the process of 1,2-H shift of the in situ-generated trifluoroethyl radical.

Comparison of efficacy of acupuncture-related therapy in the treatment of herpes zoster: A network meta-analysis of randomized controlled trials.

Objective: A systematic review and meta-analysis of randomized controlled trials (RCTs) were conducted to evaluate the efficacy and safety of acupuncture-related therapy in the treatment of herpes zoster (HZ) and to provide a reference for the clinical treatment of herpes zoster.

Methods: PubMed, Cochrane Library, EMBASE, Web of Science, CNKI, VIP database, Wanfang Database, and SinoMED Chinese and English databases were systematically searched for RCTs on acupuncture-related therapy for HZ until February 2023. Literature screening, data extraction, and risk of bias assessment were performed independently by 2 researchers.

Post-tuberculosis tracheobronchial stenosis: long-term follow-up after self-expandable metallic stents placement and development of a prediction score-the Restenosis Score.

Background: The insertion of self-expandable metallic stents (SEMS) for post-tuberculosis tracheobronchial stenosis (PTTS) was controversial. This study aimed to evaluate the efficacy and safety of SEMS for treating PTTS, and developed a scoring system for predicting the occurrence of restenosis after stenting in PTTS patients.

Methods: We conducted a retrospective review of 87 patients who were diagnosed with PTTS and experienced SEMS insertion between January 2000 and December 2017.

Differential Diagnostic Value of Histology in MPLC and IPM: A Systematic Review and Meta-Analysis.

Background: The paramount issue regarding multiple lung cancer (MLC) is whether it represents multiple primary lung cancer (MPLC) or intrapulmonary metastasis (IPM), as this directly affects both accurate staging and subsequent clinical management. As a classic method, histology has been widely utilized in clinical practice. However, studies examining the clinical value of histology in MLC have yielded inconsistent results; thus, this remains to be evaluated.

The development of bronchoscopy in China: a national cross-sectional study.

To investigate the development of bronchoscopy in China and compare it with its application in the early 21st century. The data collection was based on questionnaires. Three hundred and nineteen hospitals, which distributed across 30 provinces and 130 cities, were included in the study.

Health-related quality of life for gemcitabine and nab-paclitaxel plus radiotherapy versus gemcitabine and S-1 plus radiotherapy in patients with metastatic pancreatic cancer.

Purpose: To compare the effects of gemcitabine and nab-paclitaxel (GT) plus stereotactic body radiation therapy (SBRT) or gemcitabine and S-1 (GS) plus SBRT on health-related quality of life (HRQOL) of metastatic pancreatic cancer.

Methods: Patients with biopsy-proven and radiographically metastatic pancreatic cancer were included. HRQOL was assessed using the Chinese version of Brief Pain Inventory (BPI) and 5-level European quality of life 5-dimensions (EQ-5D-5L).

Prediction of overall survival after re-irradiation with stereotactic body radiation therapy for pancreatic cancer with a novel prognostic model (the SCAD score).

Purpose: To develop a predictive model for stratification of patients with pancreatic cancer who may achieve survival benefits from re-irradiation with stereotactic body radiation therapy (SBRT).

Methods: The score was developed based on clinical predictors of OS in 31 patients receiving two courses of SBRT with Cox proportional hazards model. Results were then validated in another cohort with 11 participants to assess the performance of the score.

Stereotactic body radiation therapy plus induction or adjuvant chemotherapy for early stage but medically inoperable pancreatic cancer: A propensity score-matched analysis of a prospectively collected database.

Background: To evaluate and compare the efficacy and safety of stereotactic body radiation therapy (SBRT) plus induction chemotherapy and SBRT plus adjuvant therapy.

Methods: Patients with radiographically resectable, biopsy-proven pancreatic cancer were enrolled. Data were prospectively collected from 2012 to 2016.

Prospective analysis of different combined regimens of stereotactic body radiation therapy and chemotherapy for locally advanced pancreatic cancer.

To identify impacts of different combined regimens of stereotactic body radiation therapy (SBRT) and chemotherapy on survival of patients with locally advanced pancreatic cancer (LAPC) and factors correlated with determinations of different combinations. Four hundred and nineteen patients with radiographically and biopsy-proven LAPC were prospectively enrolled. Factors associated with different strategies were analyzed with Chi-square test and contingency coefficients.

Prognostic role of stereotactic body radiation therapy for elderly patients with advanced and medically inoperable pancreatic cancer.

The role of stereotactic body radiation therapy for the elderly with advanced or medically inoperable pancreatic cancer was still debated. Therefore, we evaluated the value of stereotactic body radiation therapy and its association with survival of those patients. A total of 417 elderly patients were retrospectively reviewed from 2012 to 2015.
