Hepatic steatosis is characterized by substantial disruption in the liver's lipid level regulation. Konjac glucomannan (KGM) is acknowledged as a nutritious food that has the potential to prevent hyperlipidemia. This study utilized lipidomics and transcriptomics to investigate the efficacy of KGM in alleviating high-fat diet-induced hepatic steatosis by regulating lipid homeostasis.

Article Synopsis
  • * The most common types of CHD identified were atrial septal defect (53.9%), patent ductus arteriosus (33.3%), and ventricular septal defect (12.8%).
  • * A significant association was observed between a mother's history of bearing children with CHD and increased risk in offspring, while factors like smoking and drug use during pregnancy showed no substantial link to CHD prevalence.

Ethnopharmacological Relevance: Massa Medicata Fermentata, a fermented Chinese medicine, is produced by the fermentation of six traditional Chinese medicines. Liu Shenqu (LSQ) and charred Liu Shenqu (CLSQ) have been used for strengthening the spleen and enhancing digestion for over a thousand years, and CLSQ is commonly used in clinical practice. However, it is unclear whether there is a difference in the spleen strengthening and digestion effects between LSQ and CLSQ, as well as their mechanisms of action.

Konjac glucomannan (KGM) has been reported to prevent high-fat diet-induced obesity, and we study investigated whether dietary supplementation with KGM can prevent obesity by increasing energy expenditure in inguinal white adipose tissue (iWAT) of high-fat diet (HF) -fed mice. Weaned mice fed the control diet (Con), HF, or HF plus KGM (8%, w/w, HFK) were divided into three groups. The results showed that 10-week supplementation with KGM significantly reduced partial adipose tissue weight and body weight, and improved glucose tolerance.

Background: Lung adenocarcinoma (LUAD) is a fatal malignancy all over the world. Salidroside (SAL) is an active component extracted from Rhodiola rosea that has been reported to exert antitumor activity against several human cancers, containing lung adenocarcinoma (LUAD). The purpose of this study was to explore the effect and underlying mechanism of SAL in LUAD.

Cadmium pollution in rice is a threat to human health. Phytoexclusion is an effective strategy to reduce the Cd accumulation. Soil-to-root is the first step of Cd entering rice and plays a crucial role in Cd accumulation, so targeting root transporters could be an effective approach for phytoexclusion.

Objective: Patients with schizophrenia are living at the border of society and their sexuality is often neglected. The aim of the study is to explore the association among The Brief Psychiatric Rating Scale (BPRS), quality of life (QoL), Taiwanese Depression Questionnaire, and Sexual Desire Inventory in people with schizophrenia (PwS).

Methods: This study used a cross-sectional design with 277 psychiatric inpatients.

Unlabelled: Pomegranate seeds are a potential source of bioactive compounds. Nonetheless, most pomegranate seeds are discarded in the food processing industry, likely due to the lack of convincing data on their component analysis.

Methods: To reveal the main chemical constituents of pomegranate seeds, a reliable and sensitive method based on ultra-high-performance supercritical fluid chromatography coupled with electrospray ionization and quadrupole time-of-flight mass spectrometry (MS) was developed.

Gastric ulcer (GU) is one of the most prevalent digestive system diseases in humans, and it has been linked to inflammation. Previous studies have demonstrated the anti-inflammatory potential of isoalantolactone (IAL), a sesquiterpene lactone isolated from Radix Inulae. However, the pharmacological effects of IAL on GU and its mechanism of action are still unclear.

Rapid global industrialization has resulted in widespread cadmium contamination in agricultural soils and products. A considerable proportion of rice consumers are exposed to Cd levels above the provisional safe intake limit, raising widespread environmental concerns on risk management. Therefore, a generalized approach is urgently needed to enable correct evaluation and early warning of cadmium contaminants in rice products.

Unlabelled: Although observational studies have shown positive associations between body mass index (BMI) and the risk of atrial fibrillation (AF), the causal relationship is still uncertain owing to the susceptibility to confounding and reverse causation. This study aimed to examine the potential causality of BMI on AF by conducting a two-sample Mendelian randomization (TSMR) study.

Methods: The independent genetic variants associated with BMI ( = 303) at the genome-wide significant level were derived as instrumental variables (IV) from the Genetic Investigation of Anthropometric Traits (GIANT) consortium consisting of 681,275 individuals of European ancestry.

Background: The increased stroke risk associated with atrial fibrillation (AF) burden exceeding 5 min is a matter of debate. In addition, the potential linear or nonlinear relationship between AF burden and stroke risk has been largely unexplored.

Aim: To determine the association between AF burden > 5 min and the increased risk of stroke and explore the potential dose-response relationship between these two factors.

Article Synopsis
  • - Pteris vittata is a plant known for its extraordinary ability to absorb and accumulate high levels of arsenic, thanks to its efficient system for moving arsenic throughout the plant.
  • - Researchers identified a gene called PvAsE1 that plays a crucial role as an arsenite effluxer, helping to transport arsenic out of cells and into the xylem for long-distance movement in the plant.
  • - Phylogenomic studies suggest that the PvAsE1 gene emerged around 52.7 million years ago, likely as an adaptation to environmental pressures, and its discovery helps explain the unique arsenic tolerance of P. vittata.

A panel of ancestry informative SNPs (AISNPs) can be used to analyze the genetic components of a population and infer the ancestral origin of a DNA sample. Previously, we have selected a 74-AISNPs panel and used it to infer the ancestry of unknown individuals in the following ten geographical regions: Sub-Saharan Africa, North Africa, Europe, Pacific, Americas, Southwest Asia, South Asia, North Asia, East Asia and Southeast Asia. We have also established a 74-plex SNPs assay based on SEQUENOM system.
