periodontal disease is a chronic inflammatory disease which represents a primarily anaerobic gram‑negative oral infection that results in gingival inflammation, loss of attachment, bone destruction. bacterial endotoxins in the form of lipopolysaccharides (lps) that are instrumentalin generating a host‑mediated tissue destructive immune response by mobilizing their defensivecells and releasing c...

We present two cases of segmental arterial mediolysis, which can present with dissecting aneurysms or thrombosis of the visceral branches of the abdominal aorta. Segmental arterial mediolysis (SAM) causes ischemic bowel disease and has characteristic CT and angiographic features.

End-stage renal disease (ESRD) is characterized by an exceptional mortality rate, much of which is the result of cardiovascular disease (CVD). Although traditional risk factors are common in ESRD patients, they may not be sufficient alone to account for the high prevalence of CVD in this condition. Recent evidence demonstrates that chronic inflammation, a non-traditional risk factor which is ob...

Longitudinal studies of human leucocyte telomere length often report a percentage of individuals whose telomeres appear to lengthen. However, based on theoretical considerations and empirical data, Steenstrup et al. (Nucleic Acids Research, 2013, vol 41(13): e131) concluded that this lengthening is unlikely to be a real biological phenomenon and is more likely to be an artefact of measurement e...

Acute aortic dissection is a potentially lethal vascular emergency that involves the rapid development of a false blood channel within the media of the aorta. If left untreated, approximately 50% of patients die in the first 48 hours, and the mortality rate increases by 1% to 3% per hour [1,2]. Despite recent advances in diagnostic methods, misdiagnosis occurs in 25%-50% of patients on initial ...

It is widely accepted that the cerebellum acquires and maintain internal models for motor control. An internal model simulates mapping between a set of causes and effects. There are two candidates of cerebellar internal models, forward models and inverse models. A forward model transforms a motor command into a prediction of the sensory consequences of a movement. In contrast, an inverse model ...

Several decades of investigation have provided unequivocal support for the existence of an intrinsic brain reninangiotensin (Ang) system (RAS) and its involvement in the control of cardiovascular functions.1,2 Essential components of the RAS, ie, renin, angiotensinogen, Ang-converting enzyme, Ang-converting enzyme 2, type 1 Ang II, and type 2 Ang II receptors, as well as various aminopeptidases...

INTRODUCTION This Article explores the potential of community health centers (CHCs) to become a central component providing health care in America. It focuses on health centers as a proposed solution to the dual national problems of access to care and the shortage of primary care doctoring. It argues that CHCs have the capacity to address the problem of access to health services and to provide ...
