Focal depth determination of earthquakes with M≥2.5 in Jiaokou reservoir area in 2019 by multiple methods

open access: yes地震科学进展, 2023
In this paper, the focal depth of earthquakes with magnitude 2.5 or above in Jiaokou reservoir area in 2019 was determined using the CAP method, the sPL depth phase method and the double difference positioning method.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

川南长宁地区关键震源参数与地震活动性演化规律及成因研究

open access: yesDizhen xuebao
基于2010年10月至2022年7月期间长宁地区MS≥3.0地震事件,采用CAP全波形反演获取震源机制解,并结合阻尼最小二乘法反演该区域应力场的时空变化特征;同时利用多台联合反演方法提取震源参数,结合b值演化分析地震活动性演变过程。结果表明:长宁地区地震以逆冲型和走滑型为主,震源深度浅,地震活动集中分布于华蓥山断裂带西侧,最大主应力方向为WNW-ESE,整体应力场稳定,但在2019年MS6.0强震后出现短期扰动;震源参数(应力降、拐角频率、震源半径)与震级呈显著相关性,应力降均值为7.94 MPa ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

新疆柯坪地区地震震源机制解与现今应力场特征

open access: yesDizhen xuebao
基于全球质心矩张量GCMT资料,搜集整理了1991—2005年新疆柯坪地区中强地震的震源机制解;利用新疆地震台网2004—2024年宽频带波形数据,采用CAP方法补充计算了区域内MS≥3.5地震的震源机制解;采用区域应力张量阻尼方法(MSATSI)反演了柯坪地区应力空间分布,探讨了其应力场分区特征。结果表明,柯坪地区地震事件的震源机制解以逆断型为主,震源深度集中在5—30 km范围内,其中西部地区地震震源深度由南向北逐渐增加;东部地区地震事件以2024年乌什MS7.1地震序列为主,震源深度主要集中在5 ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
