Long-chain polyunsaturated fatty acids (LC-PUFAs) are crucial for human health and cannot be produced internally. Bivalves, such as oysters, serve as valuable sources of high-quality PUFAs. The enzyme fatty acid desaturase (FADS) plays a key role in the metabolism of LC-PUFAs.

This study aimed to investigate the function of exosome-derived miRNA in gallstone formation and its related molecular mechanism. Exosomes were extracted and isolated from patients with gallbladder stones and age- and gender-matched healthy controls, and exosomal miRNA expression was compared between the two groups.

In addition, cells of the same type can assume different states within an individual's body during their lifetime. Understanding the complexities of the proteome in the context of a human organism and its many potential states is a necessary requirement to understanding human biology, but these complexities can neither be predicted from the genome, nor have they been systematically measurable with available technologies.

The study revealed that Osu effectively reduced arthritis-induced swelling and bone destruction, as well as alleviating inflammation-related factors and oxidative stress in animal models. We focused the mechanism exploration on its regulatory mechanism on osteoclastogenesis in the next investigation.

Moreover, Basic fibroblast growth factor (bFGF) is a versatile biologically active substance that has crucial impact on wound healing.

The potential mechanisms that drive the intrinsic heterogeneity of breast cancer (BC) via EMT transformation have not been identified, presenting a significant obstacle in clinical diagnosis and treatment. A total of 7,602 patients have been included in this study.

Saikosaponin A (Ssa), a triterpene saponin derived from (also known as Radix bupleuri), has immunoregulatory, neuromodulatory, antiviral, anticancer, anti-convulsant, anti-inflammatory, and anti-proliferative effects. Recently, modulation of bone homeostasis was shown to involve ferroptosis.

Background: The gene is a gemcitabine (GEM) resistance gene; however, the mechanism by which it regulates GEM resistance in pancreatic cancer remains unclear.
Methods: The cell line was treated with GEM and then stimulated with . Subsequently, we constructed GEM-resistant pancreatic cancer cell lines, knocked down in these cell lines, and detected changes in the proliferation and apoptosis of drug-resistant cancer cells.
Neurovascular defects are one of the most common alterations in Alzheimer's disease (AD) pathogenesis, but whether these deficits develop before the onset of amyloid beta (Aβ) accumulation remains to be determined. Using in vivo optical imaging in freely moving mice, we explored activity-induced hippocampal microvascular blood flow dynamics in App knock-in and J20 mouse models of AD at early stages of disease progression. We found that prior to the onset of Aβ accumulation, there was a pathologically elevated blood flow response to context exploration, termed functional hyperemia.

Studies have showed an increase of the incidence of hyperuricemia among plateau populations, but little is known about the possible mechanisms. This study aims to assess the effects of high altitude on hyperuricemia and explore the corresponding mechanisms at the histological, inflammatory and molecular levels.

The aim of this study was to describe the incidence and type of aberrant hepatic artery, and to compare differences in transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma (HCC) with vs without aberrant hepatic artery.
Methods: This was a retrospective study of patients with HCC who received TACE at the same intervention center between March 15, 2020 and December 31, 2022.

Background: The cartilage stem/progenitor cells (CSPC) play a critical role in maintaining cartilage homeostasis. However, the effects of phenotypic fluctuations of CSPC on cartilage degeneration and the role of CSPC in the pathogenesis of OA is largely unknown.
Methods: The cartilage samples of 3 non-OA and 10 OA patients were collected.
High-altitude exposure has been linked to cardiac dysfunction. Silent information regulator factor 2-related enzyme 1 (sirtuin 1, SIRT1), a nicotinamide adenine dinucleotide-dependent deacetylase, plays a crucial role in regulating numerous cardiovascular diseases. However, the relationship between SIRT1 and cardiac dysfunction induced by hypobaric hypoxia (HH) remains unexplored.

Robotic PD has been routinely performed for periampullary neoplasm in periampullary neoplasm, but only a few cases in pediatric patients have been reported. Here, we report the case of a 3-year-old patient with periampullary rhabdomyosarcoma treated with robotic pylorus-preserving PD and share our experience with this procedure in pediatric patients.

Understanding the molecular mechanisms of its carcinogenic effects is crucial for lung cancer prevention and treatment. Our previous research identified the downregulation of a long noncoding RNA, maternally expressed gene 3 (MEG3), as a key factor in transforming human bronchial epithelial cells (HBECs) into malignant cells following nickel exposure.

Herein, a carboxylated multi-walled carbon nanotube (MWCNT-COOH)-ferrocene carboxylic acid (Fc-COOH) modulated NiMOF hybrid material (MWCNT-NiMOF(Fc)) has been synthesized for dual electrocatalysis of the UOR and OER. The material characterization results indicated that MWCNT-COOH and Fc-COOH were integrated into the framework structure of the NiMOF.
