Experimental cell models of insulin resistance: overview and appraisal.

Insulin resistance, a key factor in the development of type 2 diabetes mellitus (T2DM), is defined as a defect in insulin-mediated control of glucose metabolism in tissues such as liver, fat and muscle. Insulin resistance is a driving force behind various metabolic diseases, such as T2DM, hyperlipidemia, hypertension, coronary heart disease and fatty liver. Therefore, improving insulin sensitivity can be considered as an effective strategy for the prevention and treatment of these complex metabolic diseases.

[Chemical constituents and anti-inflammatory activity of Dracocephalum tanguticum].

The chemical constituents of Dracocephalum tanguticum were investigated using normal-and reverse-phase silica gel column chromatography, RP-HPLC, and other separation techniques, combined with experimental methods such as NMR, UV, IR, MS, and ORD, as well as comparison with reported literature data.

The relationship between lifecourse traumatic events and pain in an older rural South African population: A cross-sectional study.

Background: Pain in older adults is an increasing concern in low- and middle-income countries (LMICs), with literature suggesting an association with past traumatic events (TEs) in high-income settings. We aim to investigate this relationship in a population-representative sample of older adults with high burden of TEs in a rural South African community.

Methods: The Health and Aging in Africa: A longitudinal Study of an INDEPTH Community in South Africa (HAALSI) study collected data pain intensity, using the Brief Pain Inventory, and TEs with a 16-item questionnaire, from 2411 participants aged 40-79 in 2014-15.

CsCPC, an R3-MYB transcription factor, acts as a negative regulator of citric acid accumulation in Citrus.

The citric acid accumulation during fruit ripening determines the quality of fleshy fruits. However, the molecular mechanism underlying citric acid accumulation is not clearly understood yet in citrus due to the scarcity of paired germplasm that exhibits significant difference in organic acid accumulation. Two citrus triploid hybrids with distinct citric acid content in their mature fruits were herein identified from a previously conducted interploidy cross in our group, providing an ideal paired material for studying acid accumulation in citrus.

Effect of blockage of Trem1 on the M1 polarization of macrophages in the regulation dental pulp inflammation.

Dental pulp inflammation is a common and significant factor related to poor dental prognosis. Current treatment strategies primarily concentrate on managing the inflammatory response, with specific targets for intervention still under investigation. Triggering receptors expressed on myeloid cells (TREMs) are a group of receptor molecules extensively present on myeloid cell surfaces, crucial in the regulation of inflammatory process.

Neo-adjuvant radiation and intratumoral immunotherapy followed by surgery- trial for extremity soft tissue sarcoma.

Extremity soft tissue sarcoma (ESTS) is a rare malignant nonepithelial disease, calling for combined modality treatments with surgery to further improve local control rates and long-term survival, especially in patients with multiple local recurrences with or without risk of amputation. In this double-arm, open-label, Phase II clinical trial, we will enroll 30 patients with pathologically confirmed ESTS without nodal involvement or distant metastases. Patients are randomly assigned to the combination treatment group or the radiation monotherapy group.

Up-regulation of IL-1β and sPLA2-III in the medial prefrontal cortex contributes to orofacial and somatic hyperalgesia induced by malocclusion via glial-neuron crosstalk.

The medial prefrontal cortex (mPFC) has been identified as a key brain region involved in the modulation of chronic pain. Our recent study demonstrated that unilateral anterior crossbite (UAC) developed the comorbidity model of temporomandibular disorders (TMD) and fibromyalgia syndrome (FMS), which was characterized by both orofacial and somatic hyperalgesia. In the present study, UAC rats exhibited significant changes in gene expression in the mPFC.

Beautoide A, an Anti-Osteoclastogenic Sterol from Beauveria sp. NBUF147 Associated with an Irciniidae Sponge from the Marine Mesophotic Zone.

Mesophotic coral ecosystems (MCEs), located at depths ranging from 30-150 m, host some of the most diverse yet least explored marine bioresources, particularly significant for the discovery of new bioactive molecules. The fungus Beauveria sp. NBUF147, associated with an Irciniidae sponge from the mesophotic zone at a depth of 82 m, underwent chemical investigation that led to the identification of one new sterol, beautoide A (1), and one reported sterol, 3β,5α,9α-trihydroxy-(22E,24R)-ergosta-7,22-dien-6-one (2).

Glioma-Stem-Cell-Derived Exosomes Remodeled Glioma-Associated Macrophage via NEAT1/miR-125a/STAT3 Pathway.

Glioblastoma (GBM), as the most common primary brain tumor, usually results in an extremely poor prognosis, in which glioma stem cells (GSCs) and their immunosuppressive microenvironment prominently intervene in the resistance to radiotherapy and chemotherapy that directly leads to tumor recurrence and shortened survival time. The specific mechanism through which exosomes generated from GSCs support the creation of an immunosuppressive microenvironment remains unknown, while it is acknowledged to be engaged in intercellular communication and the regulation of the glioma immunosuppressive microenvironment. The elevated expression of LncRNA-NEAT1 was found in glioma cells after radiotherapy, chemotherapy, and DNA damage stimulation, and NEAT1 could promote the malignant biological activities of GSCs.

Endoscopic ultrasound-guided biliary drainage percutaneous transhepatic bile duct drainage in the management of malignant obstructive jaundice.

Background: Malignant obstructive jaundice (MOJ) is a condition characterized by varying degrees of bile duct stenosis and obstruction, accompanied by the progressive development of malignant tumors, leading to high morbidity and mortality rates. Currently, the two most commonly employed methods for its management are percutaneous transhepatic bile duct drainage (PTBD) and endoscopic ultrasound-guided biliary drainage (EUS-BD). While both methods have demonstrated favorable outcomes, additional research needs to be performed to determine their relative efficacy.
