Peripartum cardiomyopathy (PPCM) is an idiopathic form of pregnancy-induced heart failure associated with preeclampsia. Circulating factors in late pregnancy are thought to contribute both diseases, suggesting a common underlying pathophysiological process. However, what drives this process remains unclear. Using serum proteomics, we identified the senescence-associated secretory phenotype (SASP), marker cellular senescence biological aging, as most highly up-regulated pathway young women...

The etiology of peripartum cardiomyopathy remains unknown. One hypothesis is that an increase in the 16-kDa form prolactin pathogenic and suggests breastfeeding may worsen by increasing prolactin, while bromocriptine, which blocks release, be therapeutic. An autoimmune has also been proposed. authors investigated impact on cellular immunity myocardial recovery for women with IPAC (Investigations Pregnancy Associated Cardiomyopathy) study. Women who breastfed had elevated levels correlated...
Background: Heart failure with preserved ejection fraction (HFpEF) is often manifested as impaired cardiovascular reserve. We sought to determine if conducted vasodilation, which coordinates microvascular resistance longitudinally match tissue metabolic demand, becomes compromised in HFpEF. hypothesized that the vasodilator adenosine facilitates and inhibition of ADK (adenosine kinase) augments vasodilation for a more efficient myocardial perfusion improved left ventricle (LV) diastolic...

Mental arithmetic stress is known to cause forearm arterial dilation, but the venous responses, including possible changes in volume-pressure relation, have not been defined. Hence, 10 apparently normal subjects, eight men and two women, mean age 46 +/- 9 years, were studied before during mental stress. Changes volume estimated with 99mTc blood pool scintigraphy. Group variability of this measurement technique was 1.8 2.3%. A brachial pressure cuff used obtain occluding pressures 0, 10, 20,...
In this investigation blood pool scintigraphy was validated as a method to study acute changes in human forearm veins. Changes regional vascular volume (capacity) and the occluding pressure-volume (P-V) relationship induced by sublingual nifedipine (NIF) nitroglycerin (GTN) were recorded 16 patients with simultaneous data collection radionuclide mercury-in-rubber strain-gauge techniques. The standard error of estimate (Syx) between successive control measurements using 3.1% compared 3.2% for...
The work presented illustrates the feasibility of using metal ion indicators to study various aspects complexation reactions. overall aim was develop a simple method for studying metal–ligand relevant environmental migration radionuclides. reaction Xylenol Orange with zinc(II) ions is investigated as model system, initially determining variation equilibrium constant ionic strength. data are used show validity Davies equation predict constants in systems where I<0.1 M. By introduction second...
Acute cervical spinal cord injury frequently results in bradydysrhythmia, which may lead to hypotension and asystole. Such symptoms are more common the first 2 weeks after injury. Treatment modalities include atropine, epinephrine, aminophylline, pacemaker insertion. The criteria for use this population not well defined. We describe characteristics of 3 patients who required permanent, transvenous implantation recurrent symptoms. In patients, transcutaneous pacing failed provide adequate...
Morbidity and mortality increase when diastolic dysfunction accompanies coronary artery disease (CAD). An elevated stress <sup>201</sup>Tl lung-to-heart ratio (LHR) is a traditional marker of left ventricular end-diastolic pressure (LVEDP), which adds prognostic value in CAD. Since the introduction <sup>99m</sup>Tc-labeled agents, this valuable has been lost. Hence, there only limited ability to assess by myocardial perfusion imaging (MPI). <b>Methods:</b> Fifty-two consecutive patients with...
Isomer ratios in antimony and bromine fission fragments have been measured the (12C+209Bi), ( alpha +204Pb) (12C+196Pt) reactions, The values of isomer their variation with energy are accordance fragment angular momenta predicted by Fermi gas model for fissioning nucleus.
To define relative changes in intestinal vascular capacitance, we developed a model that allowed us to construct pressure-volume relationships (PVR). Thirteen alpha-chloralose-anesthetized and splenectomized dogs were studied using pneumatic constrictor small catheter change measure portal venous pressure. A lead sheet was placed beneath the abdominal wall. Relative blood volume (IBV) determined by vivo pool scintigraphy with 99mTc-labeled erythrocytes expressed as percentages corrected for...
