Low-Cycle Fatigue Damage Mechanism and Life Prediction of High-Strength Compacted Graphite Cast Iron at Different Temperatures.

Tensile and low-cycle fatigue tests of high-strength compacted graphite cast iron (CGI, RuT450) were carried out at 25 °C, 400 °C, and 500 °C, respectively. The results show that with the increase in temperature, the tensile strength decreases slowly and then decreases rapidly. The fatigue life decreases, and the life reduction increases at high temperature and high strain amplitude.

Mechanisms of visual working memory processing task-irrelevant information retrieved from visual long-term memory.

Visual working memory (VWM) can selectively filter task-irrelevant information from incoming visual stimuli. However, whether a similar filtering process applies to task-irrelevant information retrieved from visual long-term memory (VLTM) remains elusive. We assume a "resource-limited retrieval mechanism" in VWM in charge of the retrieval of irrelevant VLTM information.

The dual nature of working memory deficits: methamphetamine abusers have more impaired social working memory capacity than canonical working memory capacity.

Social working memory (WM) temporarily retains and manipulates various aspects of social information. Extensive research has highlighted impaired social cognitive functions in individuals with substance addiction. However, the specific deficit in social WM within this population remains notably understudied.

Moving stimuli enhance beat timing and sensorimotor coupling in vision.

Vision has long been known for its inefficiency in beat perception and synchronization. However, this has been challenged by the finding that moving stimuli (bouncing ball or moving bar) can significantly improve visual beat synchronization. The present study examined two possible mechanisms for this phenomenon: visual motion facilitates temporal processing or promotes sensorimotor coupling.

Neural manifestation of L2 novel concept acquisition from multi-contexts via both episodic memory and semantic memory systems.

This study aims to examine the process of L2 novel word learning through the combination of episodic and semantic memory, and how the process differs between the formation of thematic and taxonomic relations. The major approach adopted was observing the neural effects of word learning, which is manifested in the N400 from event-related potentials (ERPs). Eighty-eight participants were recruited for the experiment.

Cognitive style of field dependence-independence modulates the working memory storage of biological motion.

The biological motion refers to the continuous configuration movement of live agents in space. The perceptual processing of biological motion has the specificity of the dissociation between body form and body motion. However, there is limited evidence for whether such specificity continues when holding biological motion in working memory.

The Reactivation of working memory representations affects attentional guidance.

Recent studies have suggested that the neural activity that supported working memory (WM) storage is dynamic over time and this dynamic storage decides memory performance. Does the temporal dynamic of the WM representation also affect visual search, and how does it interact with distractor suppression over time? To address these issues, we tracked the time course of the reactivation of WM representations during visual search by analyzing the electroencephalogram (EEG) and event-related optical signals (EROS) in Experiments 1 and 2, respectively, and investigated the interaction between the representation reactivation and distractor suppression in Experiment 3. Participants had to maintain a color in WM under high- or low-precision requirement and perform a subsequent search task.

Integrative analysis of transcriptome and metabolome provide new insights into mechanisms of Capilliposide A against cisplatin-induced nephrotoxicity.

Objective: Cisplatin (CDDP) has been widely used for chemotherapy against tumours. However，the nephrotoxicity has limited its clinical use. Here, we reported a novel compound, Capilliposide A (CPS-A), to exhibit therapeutic effects on CDDP-induced acute kidney injury (AKI) and explored its potential mechanisms via transcriptome and metabolome.

Deciphering the metabolic profile and anti-colorectal cancer mechanism of Capilliposide A using ultra performance liquid chromatography mass spectrometry combined with non-targeted metabolomics studies.

Colorectal cancer is a highly prevalent malignancy that threatens human health worldwide. Despite the availability of chemotherapy as a primary treatment option, individuals with CRC undergoing frequent chemotherapy are susceptible to developing drug resistance, which can result in poor treatment outcomes. Consequently, there is an urgent need to discover new bioactive compounds for the treatment of CRC.

Capilliposide B inhibits the migration of prostate cancer by inducing autophagy through the ROS/AMPK/mTOR pathway.

Capilliposide B (CPS-B), a novel oleanane triterpenoid saponin derived from Lysimachia capillipes Hemsl, is a potent anticancer agent. However, its anticancer mechanism remains elusive. In the present study, we demonstrated the potent anti-tumor activity and molecular mechanism of CPS-B both in vitro and in vivo.

Optimization of Thermo-Mechanical Fatigue Life for Eutectic Al-Si Alloy by the Ultrasonic Melt Treatment.

The eutectic cast Al-Si alloys with excellent high-temperature and casting performance are widely used in engine pistons. During frequent starts and stops, the thermo-mechanical fatigue (TMF) is the most important failure cause. Ultrasonic melt treatment (UT) was chosen to compare and investigate the influence of micro-structures on fatigue life and damage mechanisms of as-cast (AC) eutectic Al-Si alloys under TMF loading.

Guangsangon E triggers mitochondria dysfunction and mitophagy in triple-negative breast cancer and leads to non-apoptotic cell death.

Guangsangon E (GSE) is a natural product separated from Morus alba L. It has been reported to treat lung cancer through autophagy. However, whether GSE is effective in repressing triple-negative breast cancer (TNBC) cells is yet to be elucidated.

Modulation of similarity on the distraction resistance of visual working memory representation.

Controversy exists regarding the distraction resistance of priority items in visual working memory (VWM). The protection account proposes that high-priority items resist distraction more than low-priority items, while the vulnerability account proposes that distractors impair high-priority items more. We proposed another available resource threshold account: distraction will not impair items if available resources exceed their threshold needed for sufficient processing.

Heavy metals intoxication in a patient with POEMS-like symptoms: a case report.

POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M-protein, skin changes) is a kind of plasma cell disease with complex clinical manifestations involving multiple systems. Metal poisonings through a mucocutaneous are rare in clinic and reported less in the literature. People may exposure to toxic metals through air, food, water, or inappropriate use of drugs.

More Expensive, More Attractive? The Effect of Pricing on Gift Evaluation: Differences Between Giver and Receiver.

The present research explored differences in gift evaluation between gift givers and receivers. Three studies were conducted to test how the pricing influenced the gift evaluations of givers and receivers, and whether the price-quality and price-monetary sacrifice inferences were the underlying mechanisms. The results showed that: givers evaluated high-priced gifts as better than low-priced gifts, whereas receivers evaluated low-priced gifts as better than high-priced gifts; price-quality inference mediated the effect of pricing on gift evaluations, but only for givers.
