Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

Focal mechanisms in anisotropic media [PDF]
Geophysical Journal International, 2005 SUMMARY Focal mechanisms of seismic sources in anisotropic media are more complicated than in isotropic media. Planar shear faulting produces pure double-couple (DC) mechanism in isotropy, but generally non-double-couple (non-DC) mechanism in anisotropy.

Focal adhesions as mechanosensors: A physical mechanism [PDF]
Proceedings of the National Academy of Sciences, 2005 Focal adhesions (FA) are large, multiprotein complexes that provide a mechanical link between the cytoskeletal contractile machinery and the extracellular matrix. FA exhibit mechanosensitive properties; they self-assemble and elongate upon application of pulling forces and dissociate when these forces are decreased. We propose a thermodynamic model for

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM
FEBS Letters, EarlyView.Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

The mechano-chemistry of cytoskeletal force generation [PDF]
, 2014 In this communication, we propose a model to study the non-equilibrium process by which actin stress fibers develop force in contractile cells. The emphasis here is on the non-equilibrium thermodynamics, which is necessary to address the mechanics as ...

Mechanisms of Scarring in Focal Segmental Glomerulosclerosis [PDF]
Journal of Histochemistry & Cytochemistry, 2019 Focal segmental glomerulosclerosis (FSGS) presents with scar in parts of some glomeruli and often progresses to global and diffuse glomerulosclerosis. Podocyte injury is the initial target in primary FSGS, induced by a circulating factor. Several gene variants, for example, APOL1, are associated with increased susceptibility to FSGS.

Dizhen xuebao, 2020 2019年黄海ML4.6地震序列发生在NW向苏北—滨海断裂带附近，历史上该断裂带附近曾多次发生破坏性地震。为了判断此次地震序列的发生是否与苏北—滨海断裂带活动有关，本文基于黄海ML4.6地震震中附近400 km范围内的测震台站记录，采用CAP方法计算了此次黄海地震序列中ML4.6和ML4.1地震的深度和震源机制解参数，并使用双差定位方法对该地震序列进行了重新定位。研究结果显示：2019年12月8日黄海ML4.6和12日黄海ML4.1地震的震源深度分别为20 km和21 km，位于发震区域的脆韧转换带内 ...

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Precision of the determination of focal depth from the spectral ratio of Love/Rayleigh surface waves [PDF]
, 1973 The precision with which the focal depth may be determined using Love/Rayleigh-wave spectral ratios depends on the accuracy of the models for Earth structure and for source mechanism used in the focal depth calculations. Estimates of the precision of the
