Currently, there are no studies related to the prognostic value of left ventricular diastolic dyssynchrony (LVDD) in combination with perfusion, systolic dyssynchrony, and cardiovascular risk factors in patients with normal LVEF. Therefore, we aimed to investigate the incremental prognostic value of LVDD in patients with normal LVEF and to establish a model to predict MACE.

The commercial development of lithium-sulfur batteries (LSBs) has been significantly hindered by the "shuttle effect" and the slow redox kinetics of lithium polysulfides (LiPSs). To solve these problems, researchers have designed a variety of catalysts for the conversion of LiPSs. However, the multi-step lithium polysulfide conversion process is difficult to be effectively solved by a single-function catalyst.

However, their role in cervical cancer (CC), a remarkable global malignancy affecting women, remains underexplored. Here we applied integrated epigenomic and transcriptomic profiling to delineate the distinct SE landscape in CC by analyzing paired tumor and normal tissues.

Although increasing evidence has demonstrated that Ganoderma lucidum triterpenoids (GLT) can ameliorate the motor and spatial learning disorders of AD, the underlying mechanism remains unclear. Hence, in this study, GLT were obtained by using a traditional Chinese medicine processing method, and then the effects of GLT on motor and spatial learning disorders in 5xFAD mice were investigated by using various techniques such as behavioral analysis, micro-dialysis, and neurophysiological recording.

Methods: We performed a whole genome sequencing in a discovery cohort of 3,227 unrelated Chinese participants screened for PFO via contrast transthoracic echocardiography (cTTE).
Rac/Rop proteins, a kind of unique small GTPases in plants, play crucial roles in plant growth and development and in response to abiotic and biotic stresses. However, it is poorly understood whether cotton Rac/Rop protein genes are involved in mediating cotton resistance to Verticillium dahliae. Here, we focused on the function and mechanism of cotton Rac/Rop gene GhRac9 in the defense response to Verticillium dahliae infection.

Background: The cell division cycle associated 4 (CDCA4) plays a crucial role in various biological processes and is implicated in the progression of several tumors, however, the mechanisms by which it operates in bladder cancer remain unclear.
Methods: Utilizing data from the TCGA and GEO datasets of bladder cancer patients, we analyzed the expression of CDCA4 and its prognostic significance. We then constructed stable overexpression and knockdown bladder cancer cell lines to investigate the effects of CDCA4 on cell proliferation, migration, and invasion in vitro, employing CCK-8, colony formation, transwell, and wound healing assays.
