Amphotericin B Colloidal Dispersion is Efficacious and Safe for the Management of Talaromycosis in HIV-Infected Patients: Results of a Retrospective Cohort Study in China.

Background: Amphotericin B deoxycholate (AmB-D) have potential toxic effects in the treatment of talaromycosis, and high-quality, non-generic liposomal AmB (L-AMB) is still inaccessible in many regions of China. As such, the efficacy and safety of alternative drugs warrant further investigation for the management of talaromycosis. This study aimed to compare the efficacy and safety of Amphotericin B Colloidal Dispersion (ABCD) and AmB-D for the treatment of talaromycosis in a retrospective cohort of HIV-infected patients.

Efficacy and safety of the combination of envafolimab and lenvatinib in unresectable hepatocellular carcinoma: a single-arm, multicentre, exploratory phase II clinical study.

Currently, therapeutic combinations of immune checkpoint inhibitors (ICIs) with anti-angiogenic agents have shown promising outcomes and have the potential to establish a new standard of care. The efficacy and safety of the first-line combination of envafolimab (an ICI) and lenvatinib (an anti-tumor angiogenesis drug) for the treatment of patients with inoperable hepatocellular carcinoma (HCC) have not been demonstrated. Unresectable HCC patients with an Eastern Cooperative Oncology Group (ECOG) physical status score ≤ 1 and a Child-Pugh score ≤ 7 who had not received systemic therapy were included in this single-arm, exploratory, multicentre phase II clinical study.

Enhancing Field-Like Efficiency Via Interface Engineering with Sub-Atomic Layer Ta Insertion.

The prevailing research emphasis has been on reducing the critical switching current density (J) by enhancing the damping-like efficiency (β). However, recent studies have shown that the field-like efficiency (β) can also play a major role in reducing J. In this study, the central inversion asymmetry of Pt-Co is significantly enhanced through interface engineering at the sub-atomic layer of Ta, thereby inducing substantial alterations in the β associated with the interface.

Quantitative proteomic landscape of the pathophysiology of adhesive arachnoiditis and its clinical significance: Structure and mechanism of TNC and RANBP1 proteins.

The pathophysiological mechanism of adhesive arachnoiditis (AA) is complex, involving the interaction of multiple proteins. In recent years, the development of quantitative proteomics technology has provided a new perspective to reveal its pathological mechanism. The main objective of this study was to reveal the changes of protein expression profiles in arachnoid tissue of patients with AA.

New mechanisms of PM induced atherosclerosis: Source dependent toxicity and pathogenesis.

Exposure to fine particulate matter (PM) is recognized to induce atherosclerosis, but the underlying mechanisms are not fully understood. This study used ambient PM samples collected in one of the highly polluted regions of Guanzhong Plain in China (2017-2020) and an ApoE mouse model to investigate the association between exposure to PM and atherosclerosis. Despite a substantial decrease in the ambient concentration of PM from 266.

Direct synthesis of enone-hydrazones under solvent free and additive free conditions.

A series of enone-hydrazones were synthesized through the reaction of enaminones with hydrazones under solvent-free, additive-free, and metal-catalyst-free conditions. The target products were obtained in high yields, with outstanding group tolerance, stereoselectivity, and chemical selectivity. In this work, a series of novel enaminone skeleton compounds were synthesized, and deuteration experiments showed that enone-hydrazones have different properties from traditional electron-deficient enketones.

UGT708S6 from Dendrobium catenatum, catalyzes the formation of flavonoid C-glycosides.

Background: Dendrobium catenatum is a perennial herb of the genus Dendrobium orchidaceae. It has been known as "Golden Grass, Soft Gold" since ancient times with effects of strengthening the body, benefiting the stomach, generating body fluid, nourishing Yin and clearing internal heat. The flowers of D.

Proteomic study of cerebrospinal fluid in adult tethered cord syndrome: Chemical structure and function of apolipoprotein B.

Adult tethered cord syndrome (ATCS) has a hidden onset and delayed clinical symptoms. The purpose of this study is to identify hub proteins in the cerebrospinal fluid of ATCS patients through bioinformatics analysis, and to find significant heterogeneity in these proteins between ATCS patients and non ATCS patients (control group). Firstly, differential genes were screened based on proteomic results.

Immunoproteomics Reveal Different Characteristics for the Prognostic Markers of Intratumoral-Infiltrating CD3+ T Lymphocytes and Immunoscore in Colorectal Cancer.

Tumor-infiltrating lymphocytes (TILs) and immunoscoring based on densities of CD3+ and CD8+ TILs are both favorable prognostic markers in colorectal cancer (CRC). However, determination of the molecular features of TILs, particularly their immunoproteomic signatures would require the development of large scale in situ spatiotemporal technologies. Recently, a multiplex in situ digital spatial proteomic profiling (DSP) tool GeoMx DSP has been applied to identify biomarkers predictive of therapeutic responses and to understand disease mechanisms and progression.

Construction of an interpretable model for predicting survival outcomes in patients with middle to advanced hepatocellular carcinoma (≥5 cm) using lasso-cox regression.

Background: In this retrospective study, we aimed to identify key risk factors and establish an interpretable model for HCC with a diameter ≥ 5 cm using Lasso regression for effective risk stratification and clinical decision-making.

Methods: In this study, 843 patients with advanced hepatocellular carcinoma (HCC) and tumor diameter ≥ 5 cm were included. Using Lasso regression to screen multiple characteristic variables, cox proportional hazard regression and random survival forest models (RSF) were established.

Tauroursodeoxycholic acid targets HSP90 to promote protein homeostasis and extends healthy lifespan.

As the elderly population expands, the pursuit of therapeutics to reduce morbidity and extend lifespan has become increasingly crucial. As an FDA-approved drug for chronic cholestatic liver diseases, tauroursodeoxycholic acid (TUDCA), a natural bile acid, offers additional health benefits beyond liver protection. Here, we show that TUDCA extends the lifespan and healthspan of C.

Development and validation of a nomogram for predicting microvascular invasion and evaluating the efficacy of postoperative adjuvant transarterial chemoembolization.

Background And Aim: Accurately predicting microvascular invasion (MVI) before surgery is beneficial for surgical decision-making, and some high-risk hepatocellular carcinoma (HCC) patients may benefit from postoperative adjuvant transarterial chemoembolization (PA-TACE). The purpose of this study was to develop and validate a novel nomogram for predicting MVI and assessing the survival benefits of selectively receiving PA-TACE in HCC patients.

Methods: The 1372 HCC patients who underwent hepatectomy at four medical institutions were randomly divided into training and validation datasets according to a 7:3 ratio.

Large-Scale Atomic Strain Defects on Palladium Surfaces for Enhanced Oxygen Reduction and Zinc-Air Batteries.

Designing nano-electrocatalysts rich in surface defects is critical to improve their catalytic performance. However, prevailing synthesis techniques rely heavily on complex procedures that compromise defect extensiveness and uniformity, casting a high demand for methods capable of synthesizing large-scale crystalline defects. An innovative design strategy is herein proposed that induces ample strain/dislocation defects during the growth of palladium (Pd), which is well-known as a good oxygen reduction reaction (ORR) catalyst.

Combination of biotransformation and metabolomics reveals tolfenpyrad-induced hepatocytotoxicity.

Tolfenpyrad (TFP) is an extensively used pesticide that inevitably leads to human exposure to both TFP and its transformation product residues. However, the biotransformation of TFP in humans has not been elucidated, and the toxicity of TFP along with its biotransformation products remains largely unknown. In this study, the biotransformation process of TFP was investigated using human liver microsomes and human hepatic cells.
