Vortex formation time-to-left ventricular early rapid filling relation: model-based prediction with echocardiographic validation.
Ghosh E, Shmuylovich L, Kovács SJ. Ghosh E, et al. J Appl Physiol (1985). 2010 Dec;109(6):1812-9. doi: 10.1152/japplphysiol.00645.2010. Epub 2010 Sep 23. J Appl Physiol (1985). 2010. PMID: 20864560 Free article.
Since LV wall motion generates the atrioventricular pressure gradient resulting in the early transmitral flow (Doppler E-wave) and associated vortex formation, we hypothesized that the causal relation between VFT and diastolic function (DF), parametrized by stiffness, relaxation, …

Feasibility and preliminary effects of high-intensity interval training vs. moderate-intensity continuous training on inflammatory and metabolic biomarkers in type 2 diabetes: a pilot randomized controlled trial.
Alizadeh S, Avandi M, Fico BG, Mahdieh N, Hedayati M, Rambod C, Bakhshandeh H. Alizadeh S, et al. J Diabetes Metab Disord. 2025 Oct 10;24(2):219. doi: 10.1007/s40200-025-01713-6. eCollection 2025 Dec. J Diabetes Metab Disord. 2025. PMID: 41080924
Participants over 18 years of age with T2DM, an HbA1c between 6.5% and 10%, a BMI between 24 and 35 kg/m(2), and stable medication use for at least four weeks before enrollment, were randomly assigned at a 1:1 ratio to HIIT or MICT group for eight weeks. ...RESULTS: Out of …

Effect of Megestrol Acetate and Testosterone on Body Composition and Hormonal Responses in COPD Cachexia.
Casaburi R, Nakata J, Bistrong L, Torres E, Rambod M, Porszasz J. Casaburi R, et al. Chronic Obstr Pulm Dis. 2015 Nov 9;3(1):389-397. doi: 10.15326/jcopdf.3.1.2015.0128. Chronic Obstr Pulm Dis. 2015. PMID: 28848861 Free PMC article.
Methods: We conducted a 12-week pilot study in which 4 men and 5 women (age 64 10 y, forced expiratory volume in 1 second [FEV(1)] 31 9 %pred., body mass index [BMI] 18 3 kg/m(2)) with low-normal testosterone levels (average 532 45ng/dl in men and 12.4 5.3ng/dl in women) a …

Correlates of 5-year decline in 6-min walk distance in the COPDGene cohort.
Boriek AM, Gordon J, Gwon Y, Adami A, Porszasz J, Rossiter HB, Rambod M, Chandra D, Diaz AA, Kinney GL, Make BJ, McDonald MN, Regan EA, Rennard S, van Beek EJR, Casaburi R. Boriek AM, et al. Thorax. 2026 Jun 15;81(7):664-671. doi: 10.1136/thorax-2025-224183. Thorax. 2026. PMID: 41980814
COPD participants experienced greater 6MWD decline (44.1 101.9 m, p<0.001) compared with those with normal spirometry (28.5 101.0 m, p<0.001). Only baseline 6MWD and study site accounted for appreciable fractions of 6MWD decline variance (R(2)=12.1% and 9.1%, …

Role of vortices in growth of microbubbles at mitral mechanical heart valve closure.
Rambod E, Beizai M, Sahn DJ, Gharib M. Rambod E, et al. Ann Biomed Eng. 2007 Jul;35(7):1131-45. doi: 10.1007/s10439-007-9293-y. Epub 2007 Apr 3. Ann Biomed Eng. 2007. PMID: 17404890
Mathematical analysis of vortex formation at mitral MHV closure revealed that a closing velocity of approximately 12 m/s can induce a strong regurgitant vortex which in return can instigate a local pressure drop of about 0.9 atm. ...
