An efficient method for rapid screening of triterpenoid saponins in three Glycyrrhiza species using rapid resolution liquid chromatography quadrupole time-of-flight mass spectrometry combined with mass defect filtering.

Triterpenoid saponins, a major bioactive component of liquorice, possess high hydrophilicity and often co-occur with other impurities of similar polarity. Additionally, subtle structural differences of some triterpenoid saponins bring challenges to comprehensive characterisation. In this study, triterpenoid saponins of three Glycyrrhiza species were systematically analysed using rapid resolution liquid chromatography quadrupole time-of-flight mass spectrometry (RRLC-Q-TOF-MS) coupled with mass defect filtering (MDF).

Astaxanthin alleviates chronic prostatitis/chronic pelvic pain syndrome by increasing colonization of Akkermansia muciniphila in the intestine.

Background: Astaxanthin (AST) is a natural compound with anti-inflammatory/immunomodulatory properties that has been found to have probiotic properties. However, the role and mechanism of AST in chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) are still not fully understood.

Purpose: The aim of this study was to evaluate the effect of AST on CP/CPPS and elucidate the mediating role of the gut microbiota.

Evolving community structure in the international pesticide trade networks.

The statistical properties of the international trade networks of all commodities as a whole have been extensively studied. However, the international trade networks of individual commodities often behave differently. Due to the importance of pesticides in agricultural production and food security, we investigated the evolving community structure in the international pesticide trade networks (iPTNs) of five categories from 2007 to 2018.

Obesity and cancer stem cells: Roles in cancer initiation, progression and therapy resistance.

Obesity, the global pandemic since industrialization, is the number one lifestyle-related risk factor for premature death, which increases the incidence and mortality of various diseases and conditions, including cancer. In recent years, the theory of cancer stem cells (CSCs), which have the capacity for self-renewal, metastasis and treatment resistance, has been bolstered by increasing evidence. However, research on how obesity affects CSCs to facilitate cancer initiation, progression and therapy resistance is still in its infancy, although evidence has already begun to accumulate.

Prognostic Significance of Advanced Lung Cancer Inflammation Index, a Nutritional and Inflammation Index, in Patients With Gastrointestinal Cancers: A Meta-analysis.

Previous studies have investigated the prognostic value of the advanced lung cancer inflammation index (ALI) in gastrointestinal (GI) cancers; however, the results are controversial. This meta-analysis aimed to evaluate the prognostic and clinicopathological role of ALI in patients with GI cancers. A systematic search of electronic databases was conducted to evaluate the prognostic and clinicopathological value of ALI in GI cancers.

Robustness and efficiency of international pesticide trade networks subject to link removal strategies.

The international pesticide trade network (iPTN) is a key factor affecting global food production and food security. The trade relationship is a key component in iPTNs. In a complex international trade environment, we model the impacts of uncertain factors such as trade wars, economic blockades and local wars, as removing vital relationships in the trade network.

[Effect of PKC inhibitor on renal podocyte slit diaphragm protein expression in exhausted rats].

To investigate the expression level of podocyte slit diaphragm protein in rats after one-time exhaustive exercise, to explore the effect of PKC inhibitor on the protein expression level, and to reveal the mechanism of PKC in the formation of exercise-induced proteinuria. Thirty male SD rats were randomly divided into control group (C), exercise group (E) and exercise combining with PKC inhibitor group (EPI), with 10 rats in each group. Rats in group E and EPI performed one single bout of exhaustive exercise (25 m/min), rats in group EPI were intraperitoneally injected with a PKC inhibitor (chelerythrine, 5 mg/kg) 1 day and 1 hour before exercise respectively, while rats in group C and E were injected with the same volume of saline.

To investigate the effects of different intensity of swimming training on p66Shc protein in mouse myocardium. Fifty Kunming mice were randomly divided into control group (Group C), weight-bearing swimming group (Group E), weight-bearing swimming + drug group (Group ER), non weight-bearing swimming group (Group P), non weight-bearing swimming + drug group (Group PR), with 10 mice in each group. Group C did not exercise.

Progress in Clinical Research on Gonadotropin-Releasing Hormone Receptor Antagonists for the Treatment of Prostate Cancer.

Gonadotropin-releasing hormone (GnRH) receptor agonists are still the most commonly used androgen deprivation treatment (ADT) drugs for prostate cancer in clinical practice. Currently, the GnRH receptor antagonists used for endocrine therapy for prostate cancer primarily include degarelix and relugolix (TAK-385). The former is administered by subcutaneous injection, while the latter is an oral drug.

Development of prognostic signature based on RNA binding proteins related genes analysis in clear cell renal cell carcinoma.

RNA binding proteins (RBPs) play significant roles in the development of tumors. However, a comprehensive analysis of the biological functions of RBPs in clear cell renal cell carcinoma (ccRCC) has not been performed. Our study aimed to construct an RBP-related risk model for prognosis prediction in ccRCC patients.

The efficacy and safety of lenvatinib in the treatment of solid tumors: an up-to-date meta-analysis.

We performed an updated meta-analysis to evaluate the efficacy and safety of lenvatinib in cancer patients. Databases were searched to identify relevant trials. Data were extracted to evaluate overall survival, progression-free survival, overall response rate and grade ≥3 adverse events.

Predicting highway freight transportation networks using radiation models.

Highway freight transportation (HFT) plays an important role in the economic activities. Predicting HFT networks is not only scientifically significant in the understanding of the mechanism governing the formation and dynamics of these networks, but also of practical significance in highway planning and design for policymakers and truck allocation and route planning for logistic companies. In this work we apply parameter-free radiation models to predict the HFT network in mainland China and assess their predictive performance using metrics based on links and fluxes, which can be done in reference to the real directed and weighted HFT network between 338 Chinese cities constructed from about 15.

Comparative Risks of High-Grade Adverse Events Among FDA-Approved Systemic Therapies in Advanced Melanoma: Systematic Review and Network Meta-Analysis.

Head-to-head evidence is lacking in comparative risks of high-grade adverse events (AEs) among different systemic treatment options for advanced melanoma. An up-to-date systematic review and network meta-analysis (NMA) was performed. Randomized controlled trials (RCTs) of patients with advanced melanoma were eligible if at least one intervention was the Food and Drug Administration-approved targeted or immune checkpoint inhibitors.

Multifractal analysis of financial markets: a review.

Multifractality is ubiquitously observed in complex natural and socioeconomic systems. Multifractal analysis provides powerful tools to understand the complex nonlinear nature of time series in diverse fields. Inspired by its striking analogy with hydrodynamic turbulence, from which the idea of multifractality originated, multifractal analysis of financial markets has bloomed, forming one of the main directions of econophysics.

A novel strategy to motivate the luminescence efficiency of a phosphor: drilling nanoholes on the surface.

A facile approach to fabricate nanoholes on the surface of a phosphor via a carbothermal reaction between C and BaMgAl10O17 was adopted. Drilling nanoholes greatly enhanced excitation light absorption and consequently increased the quantum efficiency, which provided new insight to help improve the luminescence efficiency of oxygen-containing phosphors.
