LIFE PREDICTION FOR HEAVY STRUCTURES BASED ON FATIGUE CRACK INITIATION AND GROWTH
The main goal for this thesis has been to perform fatigue life predictions on large components.Dierent methods were to be chosen and reviwed critically. Experimental datafor girth welded pipes was assessed by means of a version of BS7910 which were modeledfrom scratch.

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

苯磺酸左旋氨氯地平对2型糖尿病合并高血压患者血小板聚集及MMP-9/MMP-2表达的影响
【目的】 观察苯磺酸左旋氨氯地平对2型糖尿病合并高血压患者血小板聚集率(PAG)的影响,并探讨其血小板抑制作用是否通过改变血小板释放MMP-9和MMP-2的途径实现?【方法】 体外测定32例2型糖尿病合并高血压患者的血小板经苯磺酸左旋氨氯地平处理前后聚集率的变化,同时用ELISA法测定MMP-9和MMP-2表达的变化?【结果】 经苯磺酸左旋氨氯地平处理后,2型糖尿病合并高血压患者血小板的聚集率从(47.77 ± 11.92)%下降至(40.78 ± 13.97)%,P < 0.05,抑制率为(13.50

The newfound relationship between extrachromosomal DNAs and excised signal circles
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...
