Fourteen sesquiterpenoids including six new analogues (1-6) were isolated from the aerial parts of Inula lineariifolia.. The structures of the new sesquiterpenoids were determined by spectroscopic data analysis, and the structures of 1 and 6 were confirmed by single-crystal X-ray diffraction data and the modified Mosher method. All 14 compounds were examined for the inhibition of LPS-induced nitric oxide production in RAW264.7 macrophages. Compounds 6, 13, and 14 were found to inhibit nitric oxide production potently, with IC(50) values of 0.11, 0.25, and 0.10 microM, respectively.

Acute Kidney Injury (AKI) is a significant medical condition characterized by the abrupt decline in kidney function.Low-intensity pulsed ultrasound (LIPUS), a non-invasive therapeutic technique employing low-intensity acoustic wave pulses, has shown promise in promoting tissue repair and regeneration. A novel LIPUS system was developed and evaluated in rat AKI models, focusing on its effects on glomerular filtration rate (GFR), blood urea nitrogen (BUN), serum creatinine (SCr), and the Notch1-Akt-eNOS signaling pathway.

Background: Mild cognitive impairment (MCI) refers to a transitional stage between the cognitively unimpaired (CU) and dementia, which is probable in the Alzheimer's disease (AD) continuum. Neuropsychological assessments and structural MRI are primary clinical examinations applied for diagnosing MCI. Hippocampal volume (HV) and medial temporal lobe atrophy (MTA) as recognized AD biomarkers are the most frequently used imaging markers in clinical application.

Neuromodulators have major influences on the regulation of neural circuit activity across the nervous system. Nitric oxide (NO) has been shown to be a prominent neuromodulator in many circuits and has been extensively studied in the retina. Here, it has been associated with the regulation of light adaptation, gain control, and gap junctional coupling, but its effect on the retinal output, specifically on the different types of retinal ganglion cells (RGCs), is still poorly understood.

Background: Vascular contributions to dementia & Alzheimer's disease are increasing recognized. Recent studies have suggested that blood-brain barrier breakdown is an early biomarker of human cognitive dysfunction, including the early clinical stages of AD. Apolipoprotein E4(APOE4), the major AD susceptibility gene, leads to accelerated blood-brain barrier breakdown & degeneration of brain capillary pericyte that maintain blood-brain barrier integrity.
