Photoacoustic tomography, a novel non-invasive imaging modality, combines the principles of optical and acoustic imaging for use in biomedical applications. In scenarios where photoacoustic signal acquisition is insufficient due to sparse-view sampling, conventional direct reconstruction methods significantly degrade image resolution and generate numerous artifacts. To mitigate these constraints, a novel sinogram-domain priors guided extremely sparse-view reconstruction method for photoacoustic tomography boosted by enhanced diffusion model is proposed.

Physical literacy is a multidimensional concept considered fundamental for lifelong participation in physical activity. Although theories on the relationship between physical literacy and human flourishing have been proposed, no comprehensive study of this relationship in adolescents has been found. This study aimed to predict human flourishing variables (physical activity, physical health, mental health, and academic performance) that correlate highly with adolescents' physical literacy.

The results using traditional methods in limited-view PAT exhibit distortions and numerous artifacts. Here, a novel limited-view PAT reconstruction strategy that combines model-based iteration with score-based generative model was proposed.

Previous research has indicated that physical activity enhances individual resilience. However, limited studies have examined underlying psychological mechanisms between them.

Method: This cross-sectional study used a sample of 4367 Chinese primary and secondary school students enrolled in PE classes, M = 12.1, SD = 2.
Chronic stress exposure is the main environmental factor leading to cognitive impairment, but the detailed molecular mechanism is still unclear. Adenosine Deaminase acting on double-stranded RNA1(ADAR1) is involved in the occurrence of chronic stress-induced cognitive impairment. In addition, dopamine and Adenosine 3'5'-monophosphate-regulated phospho-protein (DARPP-32) gene variation affects cognitive function.

Type 2 diabetes (T2D) patients with SARS-CoV-2 infection hospitalized develop an acute cardiovascular syndrome. It is urgent to elucidate underlying mechanisms associated with the acute cardiac injury in T2D hearts. We performed bioinformatic analysis on the expression profiles of public datasets to identify the pathogenic and prognostic genes in T2D hearts.

The current k-mer counting tools are typically slow, and they require large memory and hard disk for assembled genome analysis.
Results: We propose a novel and ultra-fast k-mer counting algorithm, KCOSS, to fulfill k-mer counting mainly for assembled genomes with segmented Bloom filter, lock-free queue, lock-free thread pool and cuckoo hash table.
Purpose: This study aimed to evaluate the correlation between infrared thermal imaging-magnetic resonance imaging (MRI)-pathology of microwave ablation (MWA) of lesions in rabbit lung tumors.
Materials And Methods: MR-guided MWA was performed in nine VX2 tumor-bearing rabbits. Infrared thermal imaging, postoperative MRI, and pathological presentation were obtained and analyzed.
Objective: To investigate the role(s) of hyaluronan synthase 2 (HAS2) and hyaluronan in disease progression of endometriosis and epidermal growth factor (EGF)-induced motility changes of endometriotic cells.
Design: A case-control experimental study and in vitro primary cell culture study.
Setting: University hospital-affiliated research centers.
Multiobjective multitasking optimization (MTO), which is an emerging research topic in the field of evolutionary computation, was recently proposed. MTO aims to solve related multiobjective optimization problems at the same time via evolutionary algorithms. The key to MTO is the knowledge transfer based on sharing solutions across tasks.

In the present study, we explored whether S100A6 plays a role in the development of endometriosis. Significantly higher levels of mRNA and protein expression of S100A6 were observed in ectopic endometrial tissues compared to eutopic and normal endometrial tissues.

It plays an essential role in mediating the efflux of excess cholesterol. It is known that peroxisome proliferator-activated receptor gamma (PPARγ) promoted ABCA1 expression.

Methods: Five milliliters of peripheral venous blood were extracted form 36 patients with COPD, subdivided into stable group (CS group, n = 12), exacerbation group (CE group, n = 12), and exacerbation group with glucocorticosteroids treatment (CE + G group, n = 12), and 12 normal controls. The peripheral blood mononuclear cells (PBMCs) were isolated and the mRNA expressions of MMP-9 and TIMP-1 therein in each group were measured by RT-PCR quantitative analysis.
