Impaired Hemorheology in Exacerbations of COPD

Canadian Respiratory Journal, 2017
Background. Chronic obstructive pulmonary disease (COPD) is characterized by progressive airflow limitation. Cardiovascular-related comorbidities are established to contribute to morbidity and mortality especially during exacerbations.

Short‐term response to biologic therapy in psoriatic arthritis (PsA) is not influenced by disease duration at initiation of therapy

Arthritis Care &Research, Accepted Article.
Objectives We aimed to determine whether the short‐term response to biologics in biologic‐naïve psoriatic arthritis (PsA) is better in patients initiating biologic treatment early in the disease course. Methods PsA patients who started biologic therapy from the year 2000 to 2025 were included for analysis. Patients considered in the early treatment (ET)

RBC aggregation and cerebral blood flow in patients with occlusive CVD

Nosotchu, 1986
血液レオロジー的諸因子, 特に赤血球凝集能 (RBC-A) に焦点をあて, これらの因子が脳梗塞患者脳血流に及ぼす影響を検討した.対象は一側性テント上脳梗塞急性期23例, 非急性期20例である.脳血流 (ISI) は133Xe静注法, RBC-AはRBC-aggregometerで測定した.解析に用いた因子はRBC-A, フィブリノーゲン (Fib), Ht, 年齢, 平均動脈血圧, 発症後日数, 動脈CO2分圧, 空腹時血糖 (FBS), 血小板数, 総コレステロール, トリグリセライド, CT上の梗塞巣の体積 (LDA) である.急性期のISIと各パラメーターの単相関ではLDAのみISIと有意の負の相関を示し, 非急性期では両側ともISIとRBC-A, FibおよびFBSが有意の相関を示した ...

Molecular Rotors: From Newtonian Fluids to Functional Materials as Viscosity and Temperature Sensing Tools

Advanced Functional Materials, EarlyView.
Molecular rotors are fluorescent molecules that are sensitive to viscosity and temperature variations in the environment. They exhibit a direct correlation between fluorescence and viscosity within Newtonian fluids. However, this correlation becomes less straightforward in complex systems.

Simultaneous influences of hematocrit in the erythrocyte medium on erythrocyte aggregation and sedimentation: a kinetic study by a laser scattering technique

مجلة بغداد للعلوم, 2010
The erythrocyte aggregation is an important physiological phenomenon in the circulation of blood. It is a basic characteristic of normal blood that plays a major role in the cardiovascular system, especially in the microcirculation.

Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

Advanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

Red Blood Cell Morphology Is Associated with Altered Hemorheological Properties and Fatigue in Patients with Long COVID

Biology
Background: SARS-CoV-2 infection adversely affects rheological parameters, particularly red blood cell (RBC) aggregation and deformability, but whether these changes persist in patients suffering from Long-COVID (LC) and whether these changes are related

Cellular Responses to Mechanical Cues Across Scales: From Fundamental Insights to Translational Potential

Advanced Healthcare Materials, EarlyView.
This review examines how cellular behavior is regulated by mechanical cues transmitted through soft biomaterials, from single‐cell mechanosensing to tissue‐level adaptation. It highlights why physiological relevance, rather than model complexity alone, is critical for translational mechanobiology and introduces a scoring framework linking material ...

Clopidogrel therapy effects on cell hemostasis in acute coronary syndrome

Российский кардиологический журнал, 2008
The study was aimed at investigating cell hemostasis parameters in acute coronary syndrome (ACS), and comparing the effects of various antiaggregant medications (clopidogrel, aspirin, or their combination) on platelet (PL) and red blood cell (RBC ...

The Quantitative Assay of Antibody by Haemagglutination-inhibition: Studies by Sedimentation-enumeration of RBC Aggregates

Journal of General Virology, 1973
The sedimentation-enumeration method described (Cameron & Bradish, 1972) for quantitative studies of haemagglutination by Semliki Forest virus (SFV) has been used for the quantitative assay of antibody through its activity for combination with virus haemagglutinin.
