Traditional decision-making models conceptualize humans as adaptive learners utilizing the differences between expected and actual rewards (prediction errors, PEs) to maximize outcomes, but rarely consider the influence of violations of emotional expectations (emotional PEs) and how it differs from reward PEs. Here, we conducted a fMRI experiment (n = 43) using a modified Ultimatum Game to examine how reward and emotional PEs affect punishment decisions in terms of rejecting unfair offers. Our results revealed that reward relative to emotional PEs exerted a stronger prediction to punishment decisions.

State Key Laboratory for Quality Ensurance and Sustainable Use of Dao-di Herbs, National Resource Center for Chinese Materia Medica, China Academy of Chinese Medical Sciences Beijing 100700, China.

Black-bone silky fowls(Gallus gallus domesticus) have a long history of medicinal use, with the origin in Taihe county, Jiangxi province. The unclear family composition, inbreeding rate, and effective population size were inconducive to the resource conservation or breed improvement of black-bone silky fowls. A genome-wide analysis was performed to evaluate the genetic diversity of 80 black-bone silky fowls from random mating in three farms in 2021 in terms of minor allele frequency(MAF), expected heterozygosity(H_e), observed heterozygosity(H_o), effective population size(N_e), and runs of homozygosity(ROH).

With the development of molecular pharmacognosy, the advantages of DNA molecular markers in the identification of original plants of Chinese medicinal materials are becoming increasingly significant. To compensate for the limitations of existing markers in the quality supervision of Chinese medicinal materials, our team has independently designed a new molecular marker named DNA signature sequence(DSS). This marker is a nucleotide sequence that only appears in a specific taxonomic unit, with a length of 40 bp and high identification accuracy.

Bacterial pneumonia is a significant public health burden, contributing to substantial morbidity, mortality, and healthcare costs. Current therapeutic strategies beyond antibiotics and adjuvant therapies are limited, highlighting the need for a deeper understanding of the disease pathogenesis. Here, we employed single-cell RNA sequencing of 444,146 bronchoalveolar lavage fluid cells (BALFs) from a large cohort of 74 individuals, including 58 patients with mild (n = 22) and severe (n = 36) diseases as well as 16 healthy donors.

Rheumatoid arthritis (RA) is a common autoimmune joint disease characterized by persistent synovial inflammation and cartilage damage. The current clinical treatments primarily utilize drugs such as triptolide (TP) to address inflammation, yet they are unable to directly repair damaged cartilage. Furthermore, the persistent inflammation often undermines the effectiveness of traditional cartilage repair strategies, preventing them from achieving optimal outcomes.

Article Synopsis
  • The study examines how poly(lactic acid) (PLA) nanocomposite films with Hec-g@PS perform in extreme natural environments, focusing on their degradation and ability to adsorb Cu(II).
  • During degradation, PLA/Hec-g@PS films exhibited lower roughness and crack rates compared to standard PLA films, likely due to enhanced interactions within the material that slowed degradation.
  • The PLA/Hec-g@PS films not only extended lifespan by 1.08 times but also showed improved Cu(II) adsorption, making them promising for applications in wastewater treatment and soil remediation.

BRISC-Mediated PPM1B-K63 Deubiquitination and Subsequent TGF-β Pathway Activation Promote High-Fat/High-Sucrose Diet-Induced Arterial Stiffness.

Circ Res

January 2025

Experimental Research Center, Beijing Institute of Heart, Lung and Blood Vessel Diseases, Beijing Anzhen Hospital, Capital Medical University, China (H.J.).

Background: Metabolic syndrome heightens cardiovascular disease risk primarily through increased arterial stiffness. We previously demonstrated the involvement of YAP (Yes-associated protein) in high-fat/high-sucrose diet (HFHSD)-induced arterial stiffness via modulation of PPM1B (protein phosphatase Mg/Mn-dependent 1B)-lysine63 (K63) deubiquitination. In this study, we aimed to elucidate the role and mechanisms underlying PPM1B deubiquitination in HFHSD-induced arterial stiffness.

Experimental Research Center, China Academy of Chinese Medical Sciences Beijing 100700, China Institute of Chinese Materia Medica, China Academy of Chinese Medical Sciences Beijing 100700, China.

Myocardial infarction(MI) is a cardiovascular disease with high disability and mortality rates in clinical practice, which can subsequently develop into complications such as heart failure(HF) or cardiac rupture. Proteomics can track changes in relevant functional molecules during the occurrence and progression of diseases from an overall, molecular, systematic, and flux perspectives. Utilizing proteomic techniques to deeply explore the functional targets, molecular mechanisms, and network effects of MI and HF can aid in early diagnosis, early warning, and drug treatment of these diseases.

Background: Hepatic organoids (HOs), validated through comparative sequencing with human liver tissues, are reliable models for liver research. Comprehensive transcriptomic and proteomic sequencing of HOs throughout their induction period will enhance the platform's utility, aiding in the elucidation of liver development's molecular mechanisms.

Methods: We developed hepatic organoids (HOs) from embryonic stem cells (ESCs) through a de novo induction protocol, mimicking the stages of fetal liver development: ESCs to definitive endoderm (DE), then to foregut (FG), hepatoblasts (HB), and finally to HOs stage 1 (HO1), culminating in self-organizing HOs stage 2 (HO2) via dissociation and re-inoculation.
