Background Orthodontic tooth movement (OTM) has been shown to induce osteocyte apoptosis in alveolar bone shortly after force application. However, how osteocyte apoptosis affects orthodontic tooth movement is unknown. The goal of this study was to assess the effect of inhibition of osteocyte apoptosis on osteoclastogenesis, changes in the alveolar...

Introduction Multiple primary malignancies (MPMs) are seen in ~5% of all tumors. The aim of this study was to determine the quantitative impact on overall survival (OS) and treatment choices in patients with MPMs. Methods A retrospective analysis to determine patients with MPMs was conducted over a six-year period. Patients were defined as simultan...

Coronary artery disease (CAD) is a major cause of cardiovascular death worldwide. Prevalence of CAD is highly variable among different races. Asian Indians have been noted to have the highest CAD rates and the conventional risk factors fail to explain this difference completely. Asian Indians constitute a fifth of the global population, and the hig...

Atrial flutter (AF) is the second most common supraventricular tachyarrhythmia following atrial fibrillation. We present an interesting case of a diagnostic challenge manifested as an electrocardiogram (ECG) recording mimicking AF in a patient with Parkinson's disease (PD). A 72-year-old African-American female with history of PD presented to our E...

Peripheral arterial disease (PAD) is a common disorder associated with a high risk of cardiovascular mortality and continues to be under-recognized. The major risk factors for PAD are similar to those for coronary and cerebrovascular disease. Management includes exercise program, pharmacologic therapy and revascularization including endovascular an...

β-Catenin causes malignant growth of colonic, pancreatic and renal cancer. Four cardiac hormones, namely atrial natriuretic peptide (ANP), vessel dilator, long-acting natriuretic peptide (LANP) and kaliuretic peptide eliminate up to 80% of human pancreatic carcinomas growing in mice. Four cardiac hormones were evaluated for their ability to reduce...

The Wnt signaling pathway is a signal transduction pathway associated with oncogenesis in several human cancers. Four cardiac peptide hormones, namely vessel dilator, atrial natriuretic peptide (ANP), kaliuretic peptide, and long acting natriuretic peptide (LANP) have anticancer effects both in vitro and in vivo. These cardiac hormones were evaluat...

Background: Protein kinase-B (AKT) is a serine/threonine protein kinase that has a key role in cell proliferation and cancer cell invasiveness. Four cardiac peptide hormones, namely vessel dilator, atrial natriuretic peptide (ANP), kaliuretic peptide, and long-acting natriuretic peptide (LANP) have anticancer effects both in vitro and in vivo. Ma...

Secreted frizzled-related proteins (sFRPs) are secreted glycoproteins involved in neoplastic growth. Four hormones synthesized in the heart, namely vessel dilator, atrial natriuretic peptide (ANP), kaliuretic peptide (KP) and long-acting natriuretic peptide (LANP), have anticancer effects both in vitro and in vivo. These heart hormones were evaluat...

Signal transducers and activators of transcription (STATs) are the final "switches" that activate gene expression patterns that lead to human malignancy. Extracellular signal-regulated kinases (ERK 1/2) activate STAT 3; four cardiovascular hormones inhibit ERK 1/2 kinases, leading to the hypothesis that they may also inhibit STATs. These four cardi...

Background: Vascular endothelial growth factor (VEGF) helps control tumour growth via causing new capillaries growth in tumours. Four cardiac hormones [i.e. vessel dilator, long-acting natriuretic peptide (LANP), kaliuretic peptide (KP) and atrial natriuretic peptide (ANP)] that eliminate up to up to 86% of human small-cell lung cancers growing in...

Four cardiac peptide hormones, namely vessel dilator, long-acting natriuretic peptide (LANP), kaliuretic peptide, and atrial natriuretic peptide (ANP) have anticancer effects. The effects of these four cardiac hormones on human c-Jun-N-terminal kinase 2 (JNK2) were examined in human small cell lung cancer and human prostate cancer cells. Vessel dil...
