J Nat Prod

January 2025

Shaanxi Key Laboratory of Natural Products & Chemical Biology, College of Chemistry and Pharmacy, Northwest A&F University, Yangling, Shaanxi 712100, People's Republic of China.

A chemical investigation of the soil-derived fungus sp. XZ8 led to the isolation of five new indole alkaloids, trichindoles A-E (-), with diverse architectures, along with seven known analogues (-). Their structures were elucidated by extensive spectroscopic data analysis, and their absolute configurations were determined by single-crystal X-ray diffraction and modified Mosher's method.

A multilayer structure is a type of construction consisting of outer layers and a core, which is mainly characterized by high strength and specific stiffness, as well as the ability to dampen vibration and sound. This structure combines the high strength of traditional materials (mainly metals) and composites. Currently, sandwich structures in any configurations (types of core) are one of the main directions of technology development and research.

In this work, we present the green synthesis of complex - derived from β-hidroxymethylidene indanones by ultrasound, which allowed for the obtaining of compounds in a shorter time and with good yields. These organotin complexes were then doped with cobalt porphine and incorporated into a poly(3,4-ethylenedioxythiophene):poly(4-styrenesulfonate) matrix to manufacture composite semiconductor films. The semiconductor films were characterized through atomic force microscopy, examining their topography, Knoop hardness (around 17 HK), and tensile strength, which varied from 5 × 10 to 7 × 10 Pa.

Article Synopsis
  • The study aimed to conduct a systematic review and meta-analysis on the adherence of radiomics studies to the Radiomics Quality Score (RQS).
  • A total of 130 systematic reviews were analyzed, revealing that while adherence to RQS has improved over time, many studies still struggle to provide high-quality evidence necessary for clinical application.
  • Overall, only a small percentage of studies achieved a high RQS, indicating that the quality of radiomics research varies significantly between different imaging modalities.

Background: Cell-free DNA (cfDNA) sequence analysis to screen for fetal aneuploidy can incidentally detect maternal cancer. Additional data are needed to identify DNA-sequencing patterns and other biomarkers that can identify pregnant persons who are most likely to have cancer and to determine the best approach for follow-up.

Methods: In this ongoing study we performed cancer screening in pregnant or postpartum persons who did not perceive signs or symptoms of cancer but received unusual clinical cfDNA-sequencing results or results that were nonreportable (i.

Ta/Re layered composite material is a high-temperature material composed of the refractory metal tantalum (Ta) as the matrix and high-melting-point, high-strength rhenium (Re) as the reinforcement layer. It holds significant potential for application in aerospace engine nozzles. Developing the Ta/Re potential function is crucial for understanding the diffusion behavior at the Ta/Re interface and elucidating the high-temperature strengthening and toughening mechanism of Ta/Re layered composites.

Developing simple and efficient multi-gene expression systems is crucial for multi-trait improvement or bioproduction in transgenic plants. In previous research, an -based bicistronic system from the nonpathogenic fungus efficiently expressed multiple enzyme proteins in yeast and maize, and the heterologous enzymes successfully performed their catalytic activity to reconstruct the biosynthetic pathway in the host organism. Unlike enzyme proteins, some heterologous functional proteins (such as insecticidal proteins) are dose-dependent and they need to express sufficient levels to perform their biological functions.

Department of Neurology (EMB, DAL, NG, DBZ, LBM), University of Michigan Medical School, Ann Arbor, MI; School of Public Health (RM, LBM), University of Michigan, Ann Arbor, MI.

Objectives: It is unknown whether cognitive test scores are equivalently associated with informant-rated cognitive decline across culturally and linguistically diverse older adults. We examined the association between cognitive domain scores on the Harmonized Cognitive Assessment Protocol (HCAP) and informant-rated cognitive decline in a harmonized population-based sample of older adults.

Design, Setting, And Participants: We combined data from the HCAP sub-study of the Health and Retirement Study (HRS; 2016) and the Brain Attack Surveillance in Corpus Christi-Cognitive (BASIC-C; 2018-2020) study.

Article Synopsis
  • Interest in how plant-based diets affect the gut microbiome is increasing, but there's limited research on how different diet patterns (omnivore, vegetarian, vegan) impact microbiome profiles across various populations.
  • A study involving over 21,000 individuals found that gut microbiome profiles can effectively differentiate between these diet patterns, with a mean accuracy of 85%.
  • Key findings show that omnivore microbiomes are heavily influenced by red meat consumption, which is linked to negative health markers, while vegan microbiomes are associated with healthier outcomes and overlap with specific food and soil microbes.
