Background: Recurrent spontaneous abortion (RSA) is intricately linked to metabolic dysregulation at the maternal-fetal interface during early gestation. Abnormal levels of essential fatty acids and downstream oxylipins in decidua and chorionic villi have been identified as potential risk factors for RSA. Oxylipins have been linked to excessive inflammation, which might disrupt maternal-fetal immune tolerance, potentially contributing to RSA.

Osthole ameliorates wear particle-induced osteogenic impairment by mitigating endoplasmic reticulum stress via PERK signaling cascade.

Mol Med

December 2024

Department of Orthopedics, Nanjing Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University, Nanjing, China.

Background: Periprosthetic osteolysis and subsequent aseptic loosening are the leading causes of failure following total joint arthroplasty. Osteogenic impairment induced by wear particles is regarded as a crucial contributing factor in the development of osteolysis, with endoplasmic reticulum (ER) stress identified as a key underlying mechanism. Therefore, identifying potential therapeutic targets and agents that can regulate ER stress adaption in osteoblasts is necessary for arresting aseptic loosening.

Background: The lenticulostriate artery-neural complex (LNC), which includes the lenticulostriate artery (LSA) and surrounding neural structure, is a new concept proposed by neurologists and plays a pivotal role in hypertension-induced stroke. Conventional low-magnitude magnetic resonance imaging (MRI) has not been successfully used to reveal the microstructural changes of the LNC. This study aimed to evaluate the microstructural changes of the LNC in patients with prestroke hypertension using 7-Tesla (7-T) MRI and to identify the potential MRI biomarkers for monitoring hypertension-related neurological disorders.

Institute of Combined Injury, National Key Laboratory of Trauma and Chemical Poisoning, Army Key Laboratory of Nanomedicine, Department of Military Preventive Medicine, Army Medical University (Third Military Medical University), Chongqing, 400038, China.

Enhancing the sensitivity of radiotherapy (RT) towards renal cell carcinoma (RCC) remains a challenge because RCC is a radioresistant tumor. In this work, we design and report asymmetrically Polyethylene Glycol (PEG)ylated and amphipathic heptamethine indocyanine dyes for efficient radiosensitization of RCC treatment. They were synthesized by modifying different lengths of PEG chains as hydrophilic moieties on one N-alkyl chain of a mitochondria-targeting heptamethine indocyanine dye (IR-808), and a radiosensitizer 2-nitroimidazole (NM) as a hydrophobic moiety on another N-alkyl chain.

Biphasic Effect of Thyroid Hormone on Megakaryopoiesis and Platelet Production.

Thyroid

December 2024

State Key Laboratory of Trauma and Chemical Poisoning, Institute of Combined Injury, Chongqing Engineering Research Center for Nanomedicine, College of Preventive Medicine, Army Medical University (Third Military Medical University), Chongqing, China.

Abnormal platelet counts are frequently observed in patients with thyroid dysfunction; however, the direct impact of thyroid hormones on thrombopoiesis remains largely undefined. This study elucidates the dose-response effect of the thyroid hormone triiodothyronine (T) on megakaryocyte (MK) development and thrombopoiesis using both a murine model of hyperthyroidism/hypothyroidism and cultures of human cord blood CD34 cell-derived MKs. After the application of inhibitors to MKs, the examination of total and phosphorylated protein levels of the phosphoinositide 3-kinase (PI3K)/AKT pathway was utilized to assess the specific mechanisms of T action.

As a common clinical manifestation, muscle weakness is prevalent in people with mobility disorders. Further studies of muscle weakness have found that patients with muscle weakness present with persistent muscle inflammation, loss of muscle fibers, fat infiltration, and interstitial fibrosis. Therefore, we propose the concept of muscle microenvironment homeostasis, which explains the abnormal pathological changes in muscles through the imbalance of muscle microenvironment homeostasis.

Electronic address:

The tumor microenvironment (TME) is an intricate ecosystem where cancer cells thrive, encompassing a wide array of cellular and non-cellular components. The TME co-evolves with tumor progression in a spatially and temporally dynamic manner, which endows cancer cells with the adaptive capability of evading immune surveillance. To this end, diverse cancer-intrinsic mechanisms were exploited to dampen host immune system, such as upregulating immune checkpoints, impairing antigens presentation and competing for nutrients.
