Towards high-performance deep learning architecture and hardware accelerator design for robust analysis in diffuse correlation spectroscopy.

This study proposes a compact deep learning (DL) architecture and a highly parallelized computing hardware platform to reconstruct the blood flow index (BFi) in diffuse correlation spectroscopy (DCS). We leveraged a rigorous analytical model to generate autocorrelation functions (ACFs) to train the DL network. We assessed the accuracy of the proposed DL using simulated and milk phantom data.

Deletion of ASPP1 in myofibroblasts alleviates myocardial fibrosis by reducing p53 degradation.

In the healing process of myocardial infarction, cardiac fibroblasts are activated to produce collagen, leading to adverse remodeling and heart failure. Our previous study showed that ASPP1 promotes cardiomyocyte apoptosis by enhancing the nuclear trafficking of p53. We thus explored the influence of ASPP1 on myocardial fibrosis and the underlying mechanisms.

Development of a base editor for convenient and multiplex genome editing in cyanobacteria.

Cyanobacteria are important primary producers, contributing to 25% of the global carbon fixation through photosynthesis. They serve as model organisms to study the photosynthesis, and are important cell factories for synthetic biology. To enable efficient genetic dissection and metabolic engineering in cyanobacteria, effective and accurate genetic manipulation tools are required.

The effect of tamoxifen on estradiol, SHBG, IGF-1, and CRP in women with breast cancer or at risk of developing breast cancer: a meta-analysis of randomized controlled trials.

Background And Aim: The effects of tamoxifen on the serum levels of hormones and acute phase reactants have been studied previously, but study results have been inconsistent, especially in women with breast cancer. Hence, we conducted this meta-analysis of randomized controlled trials (RCTs) to try to clarify the effects of tamoxifen on estradiol, insulin-like growth factor 1 (IGF-1), sex hormone binding globulin (SHBG), and C-reactive protein (CRP) serum levels in women with breast cancer or at risk of developing breast cancer.

Methods: Databases were systematically searched up to December 2023.

CAND1 is reduced in the liver of NAFLD male patients and high fat diet (HFD)-fed male mice.

Insights into the Effect of SiO Particle Size on the Electrochemical Performance between Half and Full Cells for Li-Ion Batteries.

Silicon monoxide (SiO) has attracted growing attention as one of the most promising anodes for high-energy-density lithium-ion batteries (LIBs), benefiting from relatively low volume expansion and superior cycling performance compared to bare silicon (Si). However, the size of the SiO particle for commercial application remains uncertain. Besides, the materials and concepts developed on the laboratory level in half cells are quite different from what is necessary for practical operation in full cells.

Interdependent Nuclear Co-Trafficking of ASPP1 and p53 Aggravates Cardiac Ischemia/Reperfusion Injury.

Objective: ASPP1 (apoptosis stimulating of p53 protein 1) is critical in regulating cell apoptosis as a cofactor of p53 to promote its transcriptional activity in the nucleus. However, whether cytoplasmic ASPP1 affects p53 nuclear trafficking and its role in cardiac diseases remains unknown. This study aims to explore the mechanism by which ASPP1 modulates p53 nuclear trafficking and the subsequent contribution to cardiac ischemia/reperfusion (I/R) injury.

However, the precise mechanistic network underlying heart regeneration is not completely understood. As noncoding RNAs, circular RNAs (circRNAs) play essential roles in regulating cardiac physiology and pathology.

Optimal Performance and Application for Seagull Optimization Algorithm Using a Hybrid Strategy.

This paper aims to present a novel hybrid algorithm named SPSOA to address problems of low search capability and easy to fall into local optimization of seagull optimization algorithm. Firstly, the Sobol sequence in the low-discrepancy sequences is used to initialize the seagull population to enhance the population's diversity and ergodicity. Then, inspired by the sigmoid function, a new parameter is designed to strengthen the ability of the algorithm to coordinate early exploration and late development.

Cullin-associated and neddylation-dissociated 1 protein (CAND1) governs cardiac hypertrophy and heart failure partially through regulating calcineurin degradation.

Pathological cardiac hypertrophy is a process characterized by significant disturbance of protein turnover. Cullin-associated and Neddylation-dissociated 1 (CAND1) acts as a coordinator to modulate substrate protein degradation by promoting the formation of specific cullin-based ubiquitin ligase 3 complex in response to substrate accumulation, which thereby facilitate the maintaining of normal protein homeostasis. Accumulation of calcineurin is critical in the pathogenesis of cardiac hypertrophy and heart failure.

Fingolimod loaded niosomes attenuates sevoflurane induced cognitive impairments.

Neurocognition is a severe, neurological challenge caused due to sevoflurane application for induction of anaesthesia. The plan of this study is to investigate the effect of fingolimod loaded niosomes on the cognitive impairment induced by sevoflurane. Span 40 and cholesterol were used in reverse phase evaporation techniques for the preparation of fingolimod -loaded niosomes.

Targeting LncDACH1 promotes cardiac repair and regeneration after myocardium infarction.

Neonatal mammalian heart maintains a transient regeneration capacity after birth, whereas this regeneration ability gradually loses in the postnatal heart. Thus, the reactivation of cardiomyocyte proliferation is emerging as a key strategy for inducing heart regeneration in adults. We have reported that a highly conserved long noncoding RNA (lncRNA) LncDACH1 was overexpressed in the failing hearts.

Restoration of cardiac function is critical in improving the clinical outcomes of patients with HF. Long noncoding RNAs are widely involved in the development of multiple cardiac diseases, whereas their role in regulating cardiac function remains unclear.
