Alzheimer's disease (AD), as a chronic and frequent neurodegenerative disease in the elderly population, has caused a huge economic burden to society, family, and other aspects. (E)-N-(4-(((2-amino-5-phenylpyridin-3-yl) imino) methyl) pyridine-2-yl) cyclopropanecarboxamide (PIMPC), a new glycogen synthase kinase-3 (GSK-3) inhibitor, has been designed and synthesized as a potential anti-AD compound with antioxidant and metal chelating properties. In this study, we established an HPLC method for the determination of PIMPC, which has high accuracy, good sensitivity, and repeatability. This method determined the PIMPC content in rat plasma at different time points after intragastric administration to understand the pharmacokinetics (PK) process of PIMPC in rats. In addition, we preliminarily evaluated the effect of PIMPC on the liver and kidney in rats at pharmacodynamic doses. In conclusion, we have established a quantitative analysis method for PIMPC with excellent performance. And the PK process of PIMPC in rats, which was characterized by fast absorption, rapid distribution, and rapid elimination, conformed to the characteristics of the two-compartment model. In addition, long-term administration of PIMPC at therapeutic doses would not affect liver and kidney function. These studies have a certain reference for the development and research of PIMPC as a potential anti-AD drug.

3P-2L-VSC converter system suffers from complex control structure, cumbersome parameter design and slow system dynamic response under conventional double-loop scheme. In this paper, model predictive direct voltage control strategy with hybrid cost function and loss observer is designed to improve system performance and simplify system control structure. First, a model predictive direct voltage control strategy is proposed based on Euler discrete differential and integral method to enhance system dynamic response, which eliminates the cascaded intermediate link and achieves direct targets control.

Purpose: This study determined the digital mammography and ultrasonography imaging features of pure invasive micropapillary carcinoma of the breast (PIMPC) and the correlation with pathologic features.
Patients Methods: Nineteen patients diagnosed with PIMPC at Yantaishan Hospital from October 2015 to February 2022 were included in the study group. Forty patients with breast masses diagnosed as nonspecific invasive ductal carcinoma of the breast (NIDC) from July to December 2021 were included in the control group.

Glycogen synthase kinase-3 (GSK-3), a key role in the pathogenesis of Alzheimer's disease (AD), has been linked with the formation of β-amyloid (Aβ), tubulin-associated unit (tau) protein phosphorylation and apoptosis. Moreover, the excessive presence of elements such as copper (Cu) can promote Aβ aggregation and increase the risk of AD. Combined with the role of GSK-3 and metal elements in AD, a metal-chelating imine GSK-3 inhibitor N-(4-{[(2-amino-5-phenylpyridin-3-ylidene)imino]methyl}pyridin-2-yl)cyclopropanecarboxamide (PIMPC) was designed and synthesized.
