Novel patterns in discrete Ikeda map: Quint points and complex non-quantum chirality.

Chaos

January 2025

School of Mechanical and Power Engineering, Zhengzhou University, Science Road 100, 450001 Zhengzhou, China.

In this paper, the complex and dynamically rich distribution of stable phases in the well-known discrete Ikeda map is studied in detail. The unfolding patterns of these stable phases are described through three complementary stability diagrams: the Lyapunov stability diagram, the isoperiod stability diagram, and the isospike stability diagram. The adding-doubling complexification cascade and fascinating non-quantum chiral pairs are discovered, marking the first report of such structures in discrete mapping.

This paper mainly focuses on investigating the discrete event dynamic decision-making process with two noncooperative intelligent agents, defined as event dynamic games (EDGs). We introduce a novel state space model and analyze the existence of its equilibrium solution. Additionally, we apply principles of network evolution to address the challenge of event dynamic game network modeling.

Department of Computer Science and A.I. Andalusian Research Institute DaSCI "Data Science and Computational Intelligence, " University of Granada, 18071 Granada, Spain.

Reputation and punishment are significant guidelines for regulating individual behavior in human society, and those with a good reputation are more likely to be imitated by others. In addition, society imposes varying degrees of punishment for behaviors that harm the interests of groups with different reputations. However, conventional pairwise interaction rules and the punishment mechanism overlook this aspect.

Ferroptosis is a classic type of programmed cell death characterized by iron dependence, which is closely associated with many diseases such as cancer, intestinal ischemic diseases, and nervous system diseases. Transferrin (Tf) is responsible for ferric-ion delivery owing to its natural Fe binding ability and plays a crucial role in ferroptosis. However, Tf is not considered as a classic druggable target for ferroptosis-associated diseases since systemic perturbation of Tf would dramatically disrupt blood iron homeostasis.

Efficient Expression and Activity Optimization of Manganese Peroxidase for the Simultaneous Degradation of Aflatoxins AFB, AFB, AFG, and AFG.

J Agric Food Chem

January 2025

School of Food Science and Technology, International Joint Laboratory on Food Safety, Synergetic Innovation Center of Food Safety and Quality Control, Jiangnan University, Wuxi, Jiangsu 214122, P.R. China.

Aflatoxins (AFs), notorious mycotoxins that pose significant risks to human and animal health, make biodegradation extremely crucial as they offer a promising approach to managing and reducing their harmful impacts. In this study, we identified a manganese peroxidase from (Mnp) through protein similarity analysis, which has the capability to degrade four AFs (AFB, AFB, AFG, and AFG) simultaneously. The gene encoding this enzyme was subject to codon optimization, followed by cold shock induction expression using the pColdII vector, leading to the soluble expression of manganese peroxidase (Mnp) in .

Azaleas (Rhododendron simsii) are popular ornamental woody plants known for their bright colors; however, very limited studies have been reported on the process of flower petal pigmentation. In this study, we found significant differences in the anthocyanin contents of petals from different colored azaleas, and the results of quantitative real-time PCR indicated that the R2R3 MYB genes, RsMYB12, RsMYB90, and RsMYB123, showed significant expression changes during the petal coloration in azalea petals; therefore, we hypothesized that RsMYB12, RsMYB90, and RsMYB123 might involve in the coloring process of azalea petals by regulating anthocyanin synthesis. This work provides insights into the underlying mechanisms of petal pigmentation in R.

Department of Endocrinology, Cangzhou Central Hospital, No. 16 West Xinhua Road, Cangzhou, 061000, Hebei, China.

Thioredoxin-interacting protein (TXNIP), as a pivotal protein in the cellular stress response, plays a significant role in the progression of diabetic nephropathy (DN). Consequently, therapeutic strategies aimed at targeting TXNIP may offer novel interventions for patients with DN. Our study is to explore the therapeutic potential of targeting TXNIP in mitigating renal tubular injury induced by hyperglycemia.

Olfactory Dysfunction in Allergic Rhinitis.

Clin Rev Allergy Immunol

December 2024

Department of Otolaryngology-Head and Neck Surgery, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.

Olfactory dysfunction (OD) can have serious consequences as it hinders individuals from detecting important warning signals like smoke, spoiled food, and gas leaks. This can significantly impact their nutritional status, eating satisfaction, and overall quality of life. Allergic rhinitis (AR) is a common disease that greatly affects the quality of life and can lead to a decrease, distortion, or complete loss of olfactory ability.
