Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Secondary hyperparathyroidism (SHPT) is a common complication in patients receiving maintenance dialysis, driven by calcium and phosphate metabolism disturbances. Calcimimetics are central to the management of SHPT by enhancing calcium‐sensing receptor sensitivity and reducing parathyroid hormone secretion.

Knot modules and the Nakanishi index [PDF]
Proceedings of the American Mathematical Society, 2002 This paper is concerned with a knot invariant called the Nakanishi index. It is defined as the size of the smallest square matrix which presents the knot module as a \(\mathbb{Z}[t, t^{-1}]\)-module. This invariant seems to have first been defined by Kawauchi who proved that it coincides with the size of a minimal generating set for the knot module ...

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.

OFDM With Hybrid Number and Index Modulation [PDF]
IEEE Access, 2020 A novel transmission scheme is introduced for efficient data transmission by conveying additional information bits through jointly changing the index and number of active subcarriers within each orthogonal frequency division multiplexing (OFDM) subblock. The proposed scheme is different from the conventional OFDM-subcarrier number modulation (OFDM-SNM)

FEBS Letters, EarlyView.Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

Index Modulation-Aided Unsourced Random Access in the Block-Fading Channel
IEEE Open Journal of the Communications SocietyIn this article, we propose three index modulation (IM) aided unsourced random access schemes in the block-fading multiple-antenna channel. In all the proposed schemes, the signal frame is partitioned into multiple time slots, and only part of time slots
