Pyrolysis is recognized as a promising technology for waste plastics management. Although there have been many studies on pyrolysis of waste plastics, there is still a lack of in-depth research on the mechanism of synergistic effect between mixed plastics and the mechanism of product formation. In this paper, based on the pyrolysis characteristics of Polystyrene, Polyethylene, and mixed plastics (Polystyrene/Polyethylene), it is demonstrated that a synergistic effect exists in the co-pyrolysis of Polystyrene/Polyethylene and affects the pyrolysis behavior and pyrolysis products.

Background: Low-dose spiral CT imaging has been employed for cancer diagnosis, but its sensitivity and specificity were unsatisfactory. MicroRNAs have been considered an approach for screening cancers, and the function of miR-155-5p in lung cancer has been previously revealed.

Objectives: This study assessed the diagnostic value of combining low-dose spiral CT with serum miR-155-5p in lung cancer aiming to explore a novel strategy to assist the clinical cancer diagnosis.

Seneca virus A (SVA) is a newly discovered small nucleic acid virus, which can cause swine blister disease (PVD). Currently, there is no drug or vaccine. Studies have shown that SVA relies on the endolysosomal pathway to accomplish intracellular transport and release, and can disrupt lysosomal homeostasis, but its specific mechanism has not been revealed.

The abuse of hazardous agrochemicals leads to excessive toxic agricultural emissions, posing a tremendous threat to the natural surroundings and human well-being. In practice, the amount of pesticides in protecting crops is often far less than that lost into the environment through evaporation and leaching. Minimizing the use of pesticides as well as improving their use efficiency has been included in the policy of "agricultural double reduction," besides replacing the chemical fertilizer with straw returning.

In space optical applications, the piezoelectric-actuated fast steering mirror (FSM) is one of the pivotal components for high-precision beam capturing and trajectory tracking. The FSM is restrained in small-angle scanning applications due to the short actuation stroke of the incorporated piezoelectric materials. This study introduces a dual-axis sub-radian stroke FSM with a high ratio of output range to resolution and self-sensing capability, based on cascading structures for displacement amplification and flexible parts for feedback.

Article Synopsis
  • Alzheimer's disease (AD) is a neurodegenerative condition marked by amyloid-β and Tau protein buildup, leading to neuronal damage due to factors like insulin resistance and neuroinflammation.
  • Bile acids (BAs), derived from cholesterol, have shown promise in protecting neurons during AD by crossing the blood-brain barrier and interacting with various receptors.
  • BAs also influence the microbiota-gut-brain axis, which impacts immune and neuroendocrine functions, suggesting potential strategies for preventing and treating AD.

Context: Younger women have a slower progressive loss of kidney function than age-matched men and the sex advantage diminishes after menopause, suggesting a role for female hormones in the development of kidney diseases.

Objective: To examine the relationships of numerous reproductive factors and exogenous hormone use with long-term risk of chronic kidney disease (CKD) and end-stage renal disease (ESRD) in women.

Methods: A total of 260,108 women without prevalent CKD and ESRD were included.

Article Synopsis
  • - This study investigates how changes in α-fetoprotein (AFP) levels can predict survival outcomes for patients with large hepatocellular carcinoma (HCC) undergoing hepatic arterial infusion chemotherapy (HAIC).
  • - The research included 889 patients from five hospitals, analyzing AFP levels using a model that identified three distinct trajectory patterns: high stable, low stable, and sharp-falling.
  • - Findings indicate that AFP trajectory patterns, along with certain clinical stages, significantly correlate with overall survival rates, suggesting that monitoring AFP levels could enhance clinical decision-making for treating large HCC.

Tanshinone IIA (Tan IIA), a main active ingredient of salvia miltiorrhiza, has a wide range of antitumor effects, while its specific role and mechanism in head and neck squamous cell carcinomas (HNSCC) is not fully understood. Totally 59 primary HNSCC patients underwent two courses of induction chemotherapy before surgery. The association between expression of Fas-Associated Death Domain (FADD) and receptor interacting protein kinase 1 (RIPK1) and chemotherapy resistance and survival were evaluated.

The extracellular matrix (ECM) is a complex three-dimensional structure composed of proteins, glycans, and proteoglycans, constituting a critical component of the tumor microenvironment. Complex interactions among immune cells, extracellular matrix, and tumor cells promote tumor development and metastasis, consequently influencing therapeutic efficacy. Hence, elucidating these interaction mechanisms is pivotal for precision cancer therapy.

Article Synopsis
  • The study investigates the relationship between microvascular disease (MVD) and healthy lifestyle factors with mortality risk in individuals with type 2 diabetes mellitus (T2DM), finding significant differences between sexes.
  • Results show that MVD is more strongly linked to all-cause and cardiovascular mortality in women compared to men, indicating a higher risk for women.
  • Regardless of sex, maintaining a healthy lifestyle significantly lowers mortality risk, suggesting that lifestyle choices can mitigate the impacts of MVD on health outcomes.

Objective: To examine the associations between microvascular disease (MVD) and risk of stroke, dementia, and their major subtypes among individuals with type 2 diabetes mellitus (T2DM).

Methods: We included 26,173 participants with T2DM from the UK Biobank who had no known stroke or dementia at baseline. MVD burden was reflected by the presence of retinopathy, peripheral neuropathy, and chronic kidney disease.

Palm leaves are the primary literary support in South and Southeast Asia before the widespread use of paper. However, palm leaf manuscripts face the threat of information loss due to the persistent issue of ink flaking during long-term preservation. Herein, we focus on studying the botanical structure, surface properties, and surface composition of palm leaves to gain an insightful understanding of the mechanism of ink flaking.

Background: Autologous fat grafting is hampered by unpredictable graft survival, which is potentially regulated by ferroptosis. Glutathione (GSH), a powerful antioxidant used in tissue preservation, has ferroptosis-regulating activity; however, its effects on fat grafts are unclear. This study investigated the effects and mechanisms of GSH in fat graft survival.

Pancreatic cancer is a deadly cancer. More and more long noncoding RNAs (lncRNAs) have received confirmation to be dysregulated in tumors and exert the regulatory function. Studies have suggested that lncRNA insulin-like growth factor 2 antisense RNA (IGF2-AS) participates in the development of some cancers.

Platelet-stored activated blood coagulation factor X (FXa) has great potential in the gene therapy of hemophilia B (HB). However, we still need to understand more about the properties of FXa-storing platelets and how dietary factors affect them. We created transgenic mice called 2bFXa-HB, which had stable expression and storage of FXa in their platelets, resulting in the alleviation of the bleeding disorder in these mice.

Alcohol-related liver disease (ALD) is chronic liver damage caused by long-term heavy drinking with, extremely complicated pathogenesis. The current studies speculated that excessive alcohol and its metabolites are the major causes of liver cell toxicity. Autophagy is evolutionarily conserved in eukaryotes and aggravates alcoholic liver damage, through various mechanisms, such as cellular oxidative stress, inflammation, mitochondrial damage and lipid metabolism disorders.
