Objective: This study aims to investigate the association between dietary intake of niacin and vitamin B6 and the prevalence of endometriosis using data from the National Health and Nutrition Examination Survey (NHANES) 2003-2006.

Methods: We conducted a cross-sectional analysis using data from women aged 25-45 years in the 2003-2006 NHANES. Niacin and vitamin B6 intake were assessed using 24-h dietary recalls, and endometriosis status was determined by self-report.

Puerariae Lobatae Radix, as a traditional Chinese medicine(TCM) with both medicinal and edible properties, possesses effects such as relieving muscle tension and fever, generating fluids and quenching thirst, and unblocking the meridians and collaterals. Modern fermentation technology, combined with microecology and modern bioengineering, can regulate the fermentation process and efficiently produce fermentation products. In recent years, modern fermentation technology has been widely applied in TCM, enhancing or altering efficacy, reducing toxicity, and expanding the scope of clinical applications.

Chemotherapy is the primary therapy for colorectal cancer. However, its efficacy has been limited by chemoresistance, which is mainly caused by inadequate intratumoral drug accumulation and immunosuppressive microenvironments. To address these limitations, we developed a low-intensity ultrasound (LIU)-controlled and charge-reversible nanogel (R-NG), utilizing conjugated chitosan-polypyrrole polymers linked via thioketal bonds, with TiO absorbed onto its surface.

Background: Metabolic-associated steatotic liver disease (MASLD) is a novel term proposed in 2023 to replace non-alcoholic fatty liver disease (NAFLD) with the aim of better reflecting its pathogenesis and clinical manifestations. Vibration-controlled transient elastography (VCTE) is an evidence-based, non-invasive imaging device used to evaluate liver fat deposition and fibrosis. It can effectively detect liver fat infiltration greater than 5%, which is much higher than the previous ultrasound detection rate (it is difficult to detect liver fat deposition below 30%).

The bottom frame masonry structure (BFMS) in a semi-ruined state is vulnerable to secondary collapse under strong aftershocks, posing a significant risk to rescuers during post-earthquake operations. Therefore, investigating the mechanisms and characteristics of secondary collapse of BFMS in a semi-ruined state (BFMS-SR) under aftershocks is critical. This paper proposes a numerical modeling framework for BFMS under mainshock-aftershock conditions, utilizing a combination of the finite element method (FEM) and the finite discrete element method (FDEM).

Maize (Zea mays), which is a vital source of food, feed, and energy feedstock globally, has significant potential for higher yields. However, environmental stress conditions, including drought and salt stress, severely restrict maize plant growth and development, leading to great yield losses. Leucine-rich repeat receptor-like kinases (LRR-RLKs) function in biotic and abiotic stress responses in the model plant Arabidopsis (Arabidopsis thaliana), but their roles in abiotic stress responses in maize are not entirely understood.

How carbon (sucrose) and nitrogen (amino acid) accumulation is coordinatively controlled in cereal grains remains largely enigmatic. We found that overexpression of the strigolactone (SL) biosynthesis gene CAROTENOID CLEAVAGE DIOXYGENASE 8 (CCD8) resulted in greater ear diameter and enhanced sucrose and amino acid accumulation in maize kernels. Loss of ZmCCD8 function reduced kernel growth with lower sugar and amino acid concentrations.

Persistent infection with high-risk human papillomavirus (HR-HPV) is the main cause of cervical cancer. These chronic infections are characterized by high expression of the HPV E6 and E7 oncogenes and the absence of the L1 and L2 capsid proteins. The regulation of HPV gene expression plays a crucial role in both the viral life cycle and rare oncogenic events.

The concordance rate between conization and colposcopy-directed biopsy (CDB) proven cervical high-grade squamous intraepithelial lesion (HSIL) were 64-85%. We aimed to identify the risk factors associated with pathological upgrading or downgrading after conization in patients with cervical HSIL and to provide risk-stratified management based on a machine learning predictive model. This retrospective study included patients who visited the Obstetrics and Gynecology Hospital of Fudan University from January 1 to December 31, 2019, were diagnosed with cervical HSIL by CDB, and subsequently underwent conization.

Article Synopsis
  • Research aimed to clarify the relationship between the atherogenic index of plasma (AIP), physical activity (PA), and the incidence of prediabetes and diabetes in young and middle-aged adults.
  • The study analyzed 2,220 participants, revealing that higher AIP levels are significantly associated with increased occurrences of prediabetes and diabetes, particularly among individuals with low PA.
  • Results suggest that maintaining a higher level of physical activity can mitigate the risks linked to abnormal AIP levels, emphasizing the importance of exercise in preventing glucose metabolism issues.

  • * The analysis of 11 studies with 949 participants revealed significant gray matter abnormalities in specific brain regions, particularly the right postcentral gyrus, left precentral gyrus, and left cingulate gyrus, indicating that these changes may be linked to cognitive function deficits.
  • * Additionally, further investigations showed that the abnormal gray matter structure in the left cingulate gyrus is strongly associated with cognitive impairments, suggesting that these neuroanatomical changes could be used as potential imaging

Rubi fructus (Fupenzi) is the immature fruit of East China Rubi fructus, which is widely used in medicine, food, health food and other fields. Since ancient times, Fupenzi has been considered to be an important medicine for tonifying the kidney in terms of nourishing the liver and kidney, fixing essence and reducing urine, but its effective components and mechanism are not clear. In this paper, the effective components of Rubi fructus were analyzed by detecting the components of Fupenzi in vivo and in vitro.

Unlabelled: Plant height is an important agronomic trait that affects high-density tolerance and lodging resistance. However, the regulators and their underlying molecular mechanisms controlling plant height in maize remain understudied. Here, we report that knockout mutants of the calcium-dependent protein kinase gene (-KO) exhibit dramatically reduced plant height, characterized by shorter internodes and a slight decrease in node numbers.

Retinal neovascular disease is a leading cause of vision loss and blindness globally. It occurs when abnormal new blood vessels form in the retina. In this study, we utilized tetrahedral framework nucleic acids (tFNAs) as vehicles to load quercetin (QUE), a small-molecule flavonoid, forming a deoxyribonucleic acid (DNA) nanocomplex, tFNAs-QUE.

  • Research on novel PFASs (perfluorinated and polyfluorinated substances) is limited, especially regarding how they transfer across the placenta and their effects on fetuses.
  • A study of 214 mother-child pairs revealed that both maternal and fetal levels of certain novel PFASs were significant, with specific compounds like PFPeA and PFBS showing elevated exposure.
  • The analysis indicated that exposure to PFBS and PFPeA in cord serum is positively associated with increased birth weight in female infants, suggesting these substances might be more efficiently transferred through the placenta.

Aquaculture of bivalve shellfish and algae offers significant ecological benefits, yet the complex interactions between these organisms can substantially impact local carbon dynamics. This study investigated the effects of co-culturing four intertidal bivalve species Pacific oysters (Crassostrea gigas), Manila clams (Ruditapes philippinarum), Chinese clams (Cyclina sinensis), and hard clams (Mercenaria mercenaria) with microalgae (Isochrysis galbana) on specific water quality parameters, including total particulate matter (TPM), total organic matter (TOM), dissolved inorganic carbon (DIC), dissolved carbon dioxide (dCO), dissolved oxygen (DO), and ammonium (NH) concentrations. The bivalves were divided into smaller and larger groups and cultured under two conditions: with algae (WP) and without (NP), along with matched controls.

Plants generally enhance their root growth in the form of greater biomass and/or root length to boost nutrient uptake in response to short-term low nitrogen (LN). However, the underlying mechanisms of short-term LN-mediated root growth remain largely elusive. Our genome-wide association study, haplotype analysis, and phenotyping of transgenic plants showed that the crucial nitrate signaling component NIN-LIKE PROTEIN3.
