Cardiovascular (CV) diseases are a major cause of premature death and disability. Non-communicable diseases (NCD) are responsible for 52% of mortality amongst Indians, of these CV diseases are responsible for 66% of NCD mortality in India. We not only need widespread primary preventive strategy but also need effective secondary prevention protocols to reduce this. Secondary prevention in patients who already had myocardial infarction (MI) or revascularization is of utmost importance to reduce mortality, cardiac events and improve quality of life...

BACKGROUND AIMS: Previous studies identified a circulating human osteoblastic population that expressed osteocalcin (OCN), increased following fracture and pubertal growth, and formed mineralized colonies in vitro and bone in vivo. A subpopulation expressed CD34, a hematopoietic/endothelial marker. These findings led to our hypothesis that hematopoietic-derived CD34+ OCN+ cells exist in the circulation of mice and are modulated after fracture. METHODS: Flow cytometry was used to identify CD34+ OCN+ cells in male B6...

BACKGROUND: Endothelial cells play a major role in highly pathogenic avian influenza (HPAI) virus pathogenesis in gallinaceous poultry species (e.g. chicken, turkey and quail). Upon infection of gallinaceous poultry with HPAI viruses, endothelial cells throughout the body become rapidly infected, leading to systemic dissemination of the virus, disseminated intravascular coagulation, oedema and haemorrhaging. In contrast, the pathogenesis of HPAI viruses in most wild bird species (e.g...

Pregnancy-associated plasma protein-A (PAPP-A), a member of the metzincin metalloproteinase superfamily, can enhance local insulin-like growth factor (IGF) bioavailability through proteolytic cleavage of three IGF binding proteins. In patients with coronary atherosclerosis disease (CAD), elevated PAPP-A levels are significantly associated with a higher risk of cardiovascular events. Accumulating evidence indicates that this protease exerts a proatherogenic effect by altering a variety of pathological processes involved in atherosclerosis, including lipid accumulation, vascular inflammation, endothelial dysfunction, vascular smooth muscle cell proliferation and migration, plaque stability, and thrombus formation...

We have previously shown that treatment with recombinant human neuregulin-1 (rhNRG-1) improves pulmonary arterial hypertension (PAH) in a monocrotaline (MCT)-induced animal model, by decreasing pulmonary arterial remodeling and endothelial dysfunction, as well as by restoring RV function. Additionally, rhNRG-1 treatment showed direct myocardial anti-remodelling effects in a model of pressure loading of the RV without PAH. This work aimed to study the intrinsic cardiac effects of rhNRG-1 on experimental PAH and RV pressure overload, and more specifically on diastolic stiffness, at both the ventricular and cardiomyocyte level...

Neointima hyperplasia is one of the predominant features of cardiovascular diseases such as atherosclerosis, and is also responsible for the restenosis of vascular surgery including arteriovenous fistula and stent implantation. Endothelial-to-mesenchymal transition (EndMT) contributes to neointima hyperplasia by activation of the Notch or TGF-β signaling pathway. Rapamycin has been utilized as anti-restenosis drug due to its anti-proliferative activity. However, its effects on the EndMT have not been investigated yet...

The paper describes the procedure to prepare endothelial cell monolayer samples from the vascular intima, which is suitable for studying various morphological processes. To obtain high-quality multicellular specimens, it is recommended to preliminarily remove excess tissue from the outside of the vessel and to free the intima; ways to dry the surface and to separate endothelial cells are examined. The paper gives the figures of specimens stained by the Romanowsky-Giemsa method and identifies factor VIII, an endothelial marker, and Chlamydia pneumoniae inclusions in the cytoplasm of endothelial cells...

Hypertension is a major risk factor for the development of atherosclerosis. Increased carotid intima-media thickness (CIMT) is generally considered as an early marker of atherosclerosis. Recently, circulating microRNAs have been implicated both as sensitive biomarker and key regulator in development of atherosclerosis. However, the biological functions and molecular regulatory mechanisms for miR-575 on angiogenesis remain unknown. In our study, we firstly identified upregulation of circulating miR-575 in plasma of essential hypertensive patients with increased CIMT (iCIMT) compare to those patients with normal CIMT (nCIMT)...

Uterine remodeling during pregnancy and postpartum uterine involution are two fundamental, dynamic processes that are required for successful propagation of eutherian species. The uterus can increase in size up to 40-fold during pregnancy, which is largely attributed to expansion of the myometrium by hyperplasia and hypertrophy. Following pregnancy, the uterus repairs the remodeled or "damaged" tissue during uterine involution. Little is known about this repair process, particularly the role of mesenchymal stem/progenitor cells...
