Polydatin ameliorates ovalbumin‐induced asthma in a rat model through NCOA4‐mediated ferroautophagy and ferroptosis pathway

FEBS Open Bio, EarlyView.
In this research, a rat model of asthma was created using OVA, and polydatin served as an intervention. By inhibiting ferroautophagy mediated by NCOA4 and averting ferroptosis, polydatin has been demonstrated to reduce asthma. This work presents new ideas for investigating the mechanism of polydatin's ability to alleviate asthma, in addition to ...

Modelling of water balance and nitrogen cycle in vegetative filter strips [PDF]

, 2006
The retention of nutrients by 10-m-wide grass buffers and buffers under natural vegetation has been studied over 10 years in Jokioinen in southwestern Finland. The results have been compared with those from 70-m-long plots without buffers. Grass was sown

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations

Advanced Biology, Volume 9, Issue 3, March 2025.
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...

Organic livestock production [PDF]

, 2001
The development towards a sustainable agriculture has been a main objective of organic agriculture from the beginning (IFOAM, 1978), and a declared objective of the newly applied EC-Regulation (1804/1999) on organic livestock production which provides a ...

Balanço de nitrogênio em fêmeas leiteiras em confinamento alimentadas com concentrado à base de farelo de soja ou farelo de algodão Nitrogen use efficiency of growing dairy heifers fed concentrate rations based on soybean or cottonseed meal

Revista Brasileira de Zootecnia, 2010
Avaliou-se a influência do fornecimento de concentrados à base de farelo de soja ou farelo de algodão em dietas com silagem de milho sobre o balanço de nitrogênio e a produção de proteína microbiana em fêmeas leiteiras em crescimento.

Ultra-Rapid Nitrogen Balances in Man

Experimental Biology and Medicine, 1971
SummaryFasting healthy participants were in negative nitrogen balance when given glucose calories alone intravenously. Reversal of nitrogen balance from negative to positive occurred during the intravenous administration of an amino acid-glucose mixture.

LIN28B Promotes Cancer Cell Dissemination and Angiogenesis

Advanced Biology, EarlyView.
Children diagnosed with high‐risk neuroblastoma have a 5‐year event‐free survival rate of less than 50% and poor outcomes after recurrence. Deregulation of the LIN28B oncogene can be addressed in these patients. Upregulation of LIN28B is shown to support the metastatic cascade.

Different true-protein sources do not modify the metabolism of crossbred Bos taurus × Bos indicus growing heifers

Revista Brasileira de Zootecnia, 2015
The present study was conducted to investigate the effect of alternative true-protein sources to soybean meal, with different ruminal degradability, using a sugarcane-based diet, on nutrient digestion, ruminal fermentation, efficiency of microbial ...

Numerical Studies of Influencing Factors on the Homogeneity of the Powder Mixture during the Powder Spreading Process of Powder Bed Fusion–Laser Beam/Metal

Advanced Engineering Materials, EarlyView.
AISI 304L stainless steel powder is mixed with silicon nitride (Si3N4) powder and processed by PBF‐LB/M, allowing partial retention of Si3N4. The numerical approach effectively predicts the Si3N4 powder homogeneity and N content distribution on the powder bed. Recent studies have focused on the alloying of nitrogen (N) in high‐alloy stainless steels by
