Abstract
It gives us great pleasure, to write this invited overview on, Biochemistry, Pathophysiology and Medical Innovations, to the Journal of
Biochemistry and Modern Applications. In an earlier article on a similar topic, we described about a biochemistry course, that is offered at the
Cambridge University UK, called The Molecules in Medical Science, which focuses on diseases, that are familiar by name and of high
relevance like diabetes and cancer. Harvard Medical School on the other hand, says, preparation of medical school in the 21st century, should
reflect contemporary developments in medical knowledge, the pace of discovery and the permeation of biochemistry, cell biology, and genetics
into most areas of medicine. Oxford Royale Academy looks at biomedicine the following way; -Biochemistry, as the name suggests, is where
Biology meets Chemistry: it is the study of the living things, at a molecular level- or, to put it another way, the study of the very foundations of
life. On the other hand, pathophysiology deals with a variety of altered metabolism, which drives the normal physiology out of gear, and
promotes the development of risks, for various metabolic diseases. The Cardiometaboic Syndrome represents a constellation of metabolic
abnormalities that are risk factors for the development of metabolic diseases, which in turn promote vascular diseases. Major metabolic diseases
include hypertension, excess weight, obesity, and type-2 diabetes. Vascular diseases remain the number one killer worldwide, and have retained
this status for over a century. There is considerable debate, about whether the treatment of the disease itself is superior, or just management of
observed risks is enough? In view of such debates, there is a great need for the development of technologies that will facilitate early diagnosis
and better management of progression, or regression of diseases. Furthermore, advances in research in the fields of genetics, cellular biology,
molecular biology, and emerging diagnostic tools, will improve our ability to manage chronic cardiometabolic diseases. In this overview, we
have discussed advances in the various fields, the disconnect that exists between the researchers and clinicians, as well as between technologists
and the end-users.

Introduction
Of the various metabolic diseases, obesity ranks number one, with
more than 2.1 billion obese individuals globally (2013 figures,
currently far greater number), then hypertension takes the second
place, with over one billion hypertensive (1.1 billion in 2015)
worldwide, and type-2 diabetes takes the third place, with close to
half a billion diabetics. According to the European Society of
Cardiology, depending on age groups, global diabetes prevalence is
about 5% for the age group 45-59, 15% for the age group 55-59, and
close to 20% starting at age group 65-69 years. Hypertension, also
recognized as the „silent killer‟ is among the most common diseases
worldwide, and leading contributor to the acute vascular events,
associated with heart attacks and stroke.
Hypertension is divided to two groups, primary (or essential)
hypertension, which has no clear etiology and accounts for 85% of
cases. The second group is called secondary, which accounts for less
than 5% of cases [1-6]. A well-known risk factor for hypertension is
the family history and increased sodium intake. Dietary salt is the
most important factor contributing to hypertension. It is mainly
attributed to impaired renal capacity to excrete sodium.
Other than therapeutic interventions aimed at improving sodium
clearance from kidneys, major clinical trials have been aimed at
modification of dietary sodium intake. In view of this fact,
recommended dietary guidelines limit sodium to less than 2,300 mg
per day. Smoking and excess consumption of alcohol, metabolic
syndrome, and obesity are other risk factors. In addition, there seems
to be a positive correlation between central abdominal obesity (South
Asian Phenotype) and increased blood pressure. A land mark study,
demonstrating the benefits of reducing salt intake on hypertension is
the Inter Salt Study, which is a meta-analysis focusing on salt and
blood pressure in 28 randomized trials.
At the cellular and molecular level, it has been shown that renal beta-
2 adrenoreceptor stimulation in the kidneys leads, to decreased
transcription of the gene encoding WNK4, a negative regulator of Na
(+) reabsorption through Na (+) Cl (-) contransporator in the distal
convoluted tubes, resulting in salt-dependent hypertension [5,6]. How
about the excess weight and obesity? The early origin of adult disease
hypothesis suggests that obesity can develop in offspring from
mothers exposed, to metabolic hardship or intrauterine growth
