Cancer-associated fibroblasts regulating nanomedicine to overcome sorafenib resistance in hepatocellular carcinoma with portal vein tumor thrombus.

Portal vein tumor thrombus (PVTT) is a common and severe indicator in advanced hepatocellular carcinoma (HCC), characterized by a poor prognosis and limited response to existing therapies. Cancer-associated fibroblasts (CAFs) play an important role in promoting HCC metastasis and contribute to resistance against sorafenib (SOR) resistance, which is a standard treatment for advanced HCC. The data from single-cell RNA sequencing highlights the critical role of C-X-C motif chemokine ligand 12 (CXCL12) in the activation of CAFs.

Personalized 3D Vaccine Integrates Immunotherapy and Antiangiogenic Therapy to Prevent Oral Squamous Cell Carcinoma Recurrence.

The immune-suppressive microenvironment and extensive tumor angiogenesis are key contributors to the high recurrence and mortality rates of oral squamous cell carcinoma (OSCC). To address these challenges, a personalized 3D-printed anti-tumor vaccine (3D-Vax-L) is developed that integrates whole tumor antigens from postoperative tissue lysates with the angiogenesis inhibitor, lenvatinib. This vaccine not only possesses inherent adjuvant properties but also mimics the functions of lymph nodes through its porous structure, facilitating the recruitment and maturation of immune cells.

The intricate relationship between stress and animal welfare: from historical perspective to new avenues.

We discuss the intricate relationship between the evolution of the concept of stress and the development of the concept of animal welfare. After a brief review of the main concepts of animal welfare, we analyse important steps in the evolution of the concept of stress, starting from the mechanistic approach of the General Adaptation Syndrome to the recent integrative allostatic theory. We show how, over time, each concept of stress has informed the development of the concept of animal welfare.

De novo transcriptome assembly database for 100 tissues from each of seven species of domestic herbivore.

Domesticated herbivores are an important agricultural resource that play a critical role in global food security, particularly as they can adapt to varied environments, including marginal lands. An understanding of the molecular basis of their biology would contribute to better management and sustainable production. Thus, we conducted transcriptome sequencing of 100 to 105 tissues from two females of each of seven species of herbivore (cattle, sheep, goats, sika deer, horses, donkeys, and rabbits) including two breeds of sheep.

Physiological-biochemical responses and transcriptomic analysis reveal the effects and mechanisms of sulfamethoxazole on the carbon fixation function of Chlorella pyrenoidosa.

However, the toxic effects and mechanisms of SMX, especially for low concentration and long-term exposure, are still not clear. This study investigated the effects and mechanisms of SMX on carbon fixation-related biological processes of Chlorella pyrenoidosa at population, physiological-biochemical, and transcriptional levels.

Tryptophan improves antioxidant capability and meat quality by reducing responses to stress in nervous Hu sheep.

In sheep, the effect of tryptophan (Trp) on behavioural traits that are associated with temperament and any effects on production traits is unknown. The hypothesis of this study is that the supplementation of Trp would improve temperament by enhancing serotonin production, which is beneficial to meat production subsequently in sheep. Twelve ewes that had the lowest and 12 ewes that had the highest behavioural responses to human contact were selected into the calm and the nervous groups respectively.
