Retinopathy in Parkinson's disease: A potential biomarker for early diagnosis and clinical assessment.

Parkinson's disease (PD) is a prevalent neurodegenerative disorder caused by degeneration of dopaminergic neurons, originating from the substantia nigra pars compacta, and characterized by motor symptoms such as bradykinesia, muscle rigidity, resting tremor, and postural instability, as well as non-motor symptoms such as anxiety, depression, reduced sense of smell, cognitive impairment, and visual dysfunction. Emerging evidence highlights the retina as a promising site for non-invasive exploration of PD pathology, due to its shared embryonic origin with the central nervous system. In recent years, with the development of ophthalmic technology, the acquisition of retinal-related function and structure has gradually become mature.

Melatonin ameliorates age-related sarcopenia by inhibiting fibrogenic conversion of satellite cell.

The fibrogenic conversion of satellite cells contributes to the atrophy and fibrosis of skeletal muscle, playing a significant role in the pathogenesis of age-related sarcopenia.

CMTM7 shapes the chronic inflammatory and immunosuppressive tumor microenvironment in hepatocellular carcinoma as an M2 macrophage biomarker.

Transmembrane domain-containing 7 (CMTM7) is a protein located at the plasma membrane. It plays a role in regulating the development and immune microenvironment of tumor cells. However, the impact of CMTM7 on hepatocellular carcinoma (HCC) is not well understood.

Preparation of matrix-matched calibration standards for accurate determination of elemental concentrations in uric acid stones by LA-ICP-MS.

Accurate determination of elemental concentrations in uric acid (UA) stones is crucial for understanding their formation process. However, the lack of matrix-matched calibration standards has limited the application of laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) in this field. This study addresses this limitation by preparing a synthetic UA precipitate (UA-1) doped with 17 elements using a recrystallization method.

A sensitive electrochemical sensor based on CoWO/multi-walled carbon nanotubes for the selective determination of chlorpromazine hydrochloride.

In this work, a novel electrochemical sensor based on cobalt tungstate/multi-walled carbon nanotube (CoWO/MWCNT) nanocomposites has been used to detect chlorpromazine hydrochloride (CPZ). The CoWO/MWCNT nanocomposite was obtained by solvothermal technology and ultrasonic method and analyzed using different characterization techniques such as scanning electron microscopy (SEM), X-ray diffractometry (XRD), energy-dispersive spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). The electrochemical behavior of CoWO/MWCNT/GCE was explored using cyclic voltammetry (CV).

The role of miR-152 in urological tumors: potential biomarkers and therapeutic targets.

Urological malignant tumors pose a significant threat to human health, with a high incidence rate each year. Prostate cancer, bladder cancer, and renal cell carcinoma are among the most prevalent and extensively researched urological malignancies. Despite advancements in research, the prognosis for these tumors remains unfavorable due to late detection, postoperative recurrence, and treatment resistance.

RNF38 promotes gilteritinib resistance in acute myeloid leukemia via inducing autophagy by regulating ubiquitination of LMX1A.

Background: Gilteritinib is a commonly used targeted drug for acute myeloid leukemia (AML), but the emergence of gilteritinib resistance greatly reduces the therapeutic effect. RING finger protein 38 (RNF38), a protein with RING Finger domain and E3 ubiquitin ligase activity, has been implicated in tumorigenesis and drug resistance. However, the role and mechanism of RNF38 in the gilteritinib resistance of AML remains unclear.

The role of AIM2 in inflammation and tumors.

Absent in melanoma 2 (AIM2) serves as an intracellular nucleic acid sensor that predominantly detects double-stranded DNA (dsDNA) within the cells. This detection initiates the assembly of inflammasome and activates the inflammasome signaling cascade, resulting in the production of inflammatory mediators and the cleavage of Gasdermins. Consequently, these processes culminate in inflammatory responses and pyroptotic cell death.
