Width dependent auto-oscillating properties of constriction based spin Hall nano-oscillators [PDF]
, 2020 We study the current tunable microwave signal properties of nano-constriction based spin Hall nano-oscillators (SHNOs) in oblique magnetic fields as a function of the nano-constriction width, $w=$~50--140 nm. The threshold current is found to scale linearly with $w$, defining a constant threshold current density of $J_{th}=$ 1.7 $\times$ 10$^{8}$ A/cm$^

Annexin A4 and A6 induce membrane curvature and constriction during cell membrane repair
Nature Communications, 2017 Efficient cell membrane repair mechanisms are essential for maintaining membrane integrity and thus for cell life. Here we show that the Ca2+- and phospholipid-binding proteins annexin A4 and A6 are involved in plasma membrane repair and needed for rapid

Cell type specificity of neurovascular coupling in cerebral cortex
eLife, 2016 Identification of the cellular players and molecular messengers that communicate neuronal activity to the vasculature driving cerebral hemodynamics is important for (1) the basic understanding of cerebrovascular regulation and (2) interpretation of ...

May-Thurner Syndrome, an Often Overlooked Cause of Deep Vein Thrombosis: A Case Report
Oman Medical Journal, 2021 Deep vein thrombosis (DVT) is a common medical condition, but the predisposing anatomical factors, which may be amenable to definitive treatment, are usually overlooked. Therefore, a high index of clinical suspicion is the key to early diagnosis.

Constriction of the mitochondrial inner compartment is a priming event for mitochondrial division
Nature Communications, 2017 Mitochondrial division is critical for the maintenance and regulation of mitochondrial function, quality and distribution. This process is controlled by cytosolic actin-based constriction machinery and dynamin-related protein 1 (Drp1) on mitochondrial ...

Frontiers in Physiology, 2021 Aim: Cyclic stretch of vascular tissue at any given pressure reveals greater dimensions during unloading than during loading, which determines the cardiac beat-by-beat hysteresis loop on the pressure-diameter/volume relationship.

Limb salvage procedure in occlusion of the infrapopliteal arteries [PDF]
Vojnosanitetski Pregled, 2007 Background/Aim. Limb salvage is a procedure for treatment of the causes of ischemia in the peripheral arteries of the lower limbs. This procedure consists of percutaneous transluminal angioplasty (PTA) of arteries of the infrapopliteal segment in the ...

eLife, 2018 To ensure timely cytokinesis, the equatorial actomyosin contractile ring constricts at a relatively constant rate despite its progressively decreasing size. Thus, the per-unit-length constriction rate increases as ring perimeter decreases.

Behavioral Sciences, 2020 We introduce a typological characterization of possible human heterosexual couples in terms of the concordance-opposition of the orientations of their active and receptive areas as defined by the tie-up theory.

Turgor Pressure and Possible Constriction Mechanisms in Bacterial Division
Frontiers in Microbiology, 2018 Bacterial cytokinesis begins with the assembly of FtsZ into a Z ring at the center of the cell. The Z-ring constriction in Gram-negative bacteria may occur in an environment where the periplasm and the cytoplasm are isoosmotic, but in Gram-positive ...
