However most taste receptors arc coupled to Gproteins and second messenger systems blood pressure chart jnc carvedilol 6.25 mg free shipping. Tastants defuse through lipid phase of membrane and bind to intracellular targets bypassing usual receptor binding step arrhythmia back pain cheap carvedilol 6.25 mg online. Several compounds that act as bitter and sweet tastants have amphiphilic structures that allow them to penetrate taste cell membrane pulse pressure 100 6.25 mg carvedilol buy amex. Alteration in taste is common disorder associated with several types of diseases as well as use of drugs blood pressure over 180 generic 25 mg carvedilol visa. Knowledge of cellular and molecular mechanism involved in taste transduction is useful, in developing drugs for the treatment of taste disorders. Odor signalling Eukoryotic organisms including man evolved complex olfactory system which give ability to identify odors, chemicals or scents in environment. The molecular mechanisms involved in this perception of odor are currently being investigated intensively using molecular biology, electrophysiology, Neurobiology techniques. Biochemical Communications 689 Briefly odor perception involves initial interaction of odorant molecule with receptor proteins of olfactory system which is then transmitted to brain where it is processed and interpreted. Each olfactory neuron carries on its surface at least ten hair like cilia containing receptor proteins which recognizes and binds odorant molecules. From more than thousand genes each olfactory neuron expresses only one receptor subtype. Odor signaling pathway Odor signaling occurs through receptor mediated second messenger pathway. This in turn leads to activation of olfactory neuron and electrical signals are generated. Through thin nerve processes these signals directly pass through distinct micro domain known as glomeruli in the olfactory bulb of the brain. From the glomeruli in the olfactory bulb information is passed to the other parts of the brain for interpretation. Our nose is able to detect and discriminate among thousands of odorants with diverse chemical structures and properties which requires enormous molecular recognition capacity. This is achieved through distinct receptor proteins present in the nasal cavity which are able 690 Medical Biochemistry to bind only specific molecules. Further specific odorant detection may involve a signalling pathway that is distinct from those used by other odorants. Knowledge of odor signalling may prove useful for treatment of olfactory disturbances or smell disturbances associated with infections like cold, drug use and diseases. Molecular basis of odor recognition is useful in development of electronic nose or sensors for odorants present in environment. Signal transduction for muscle contraction Neuromuscular junction is the site of signal transduction for muscle contraction. The part of muscle membrane that is in contact with nerve terminal is known as motor end plate. It is thrown into several folds which increases surface area for neurotransmitter action. The nerve end contains several vesicles filled with neurotransmitter acetylcholine. The sequence of events that occur at neuromuscular junction during signal transduction for muscle contraction are as follows. This leads to rupture of vesicle by the calcium ions and release of acetylcholine into synaptic cleft. In the synaptic cleft acetylcholine released binds receptors present in motor end plate. When two molecules of acetylcholine binds to receptors it undergoes conformational change and opens cation channels present in motor end plate. It results in depolarization of muscle membrane and production of end plate potential. Transmission of the end plate potential to adjacent muscle membrane leads to generation of action potential which results in muscle contraction. Acetylcholine dissociates from its receptors with in two milliseconds by diffusion and hydrolyzed by acetylcholine esterase. Choline is taken up by nerve terminal through active transport process and used for synthesis of acetylcholine. Botulinum toxin interfere with muscle contraction by inhibiting acetylcholine release into synaptic space at neuromuscular junction and cause muscle paralysis.

Diabetes mellitus associated with other conditions like pancreatic disease arrhythmia zoloft discount 25 mg carvedilol amex, genetic diseases, drug or chemicals induced. They are (a) Glucokinase gene mutation Mutations of glucokinase gene leads to deficiency of this enzyme. Patients affected with this condition have moderate fasting hyperglycemia from birth. However these patients have normal fasting glucose in childhood but develop hyperglycemia in early adulthood. Coma and death may occur if untreated 356 Medical Biochemistry Chronic effects of diabetes mellitus In long standing or chronic cases of diabetes in addition to the above symptoms atherosclerosis, coronary artery disease, diabetic neuropathy, diabetic nephropathy and diabetic cataract (retinopathy) develops. In diabetic neuropathy, there is general loss of peripheral sensation particularly of lower limbs. The delayed wound healing and loss of sensation in lower limbs are responsible for development of diabetic foot and amputation. Diabetic nephropathy is due to thickening of capillary basement membrane and increased permeability of capillaries. Metabolic changes in diabetes mellitus Some of metabolic changes in diabetes are similar to starvation. Main differences between diabetes and starvation are blood glucose and insulin levels. In starvation, blood glucose level remain normal whereas in diabetes it is elevated. The insulin level is normal in starvation and in diabetes insulin action is minimal. Since insulin is antagonist to glucagon, in diabetes glucagon actions are unopposed. Carbohydrate metabolism In diabetes the blood glucose level increases because of decreased utilization of glucose by peripheral tissues. Due to lack of insulin peripheral tissues like adipose tissue and skeletal muscle are unable to take up glucose. So glucose conversion to fat and glycogen is blocked in adipose tissue and skeletal muscle respectively. In addition, glucagon stimulates gluconeogenesis and glycogenolysis in liver which contributes to blood glucose. Therefore, blood glucose level raises (hyperglycemia) and when the blood sugar level exceeds renal threshold value glucose is excreted in urine (glycosuria). Mechanism of hyperglycemia induced diabetic complications Earlier, it was mentioned that how hyperglycemia leads to complications in diabetes is unclear. However, research carried out recently provided mechanism by which elevated levels of glucose disturb cellular properties. Persistent hyperglycemia in chronic diabetes induce oxidative stress, which leads to increased generations of reactive oxygen species in mitochondria. This results in variety of harmful oxidative products, which are known to complicate diabetic pathology. Some of the biochemical mechanisms involved in hyperglycemia induced organ damage are A. As a result of this, plasma free fatty acid level raises and more fatty acids enter liver for utilization. When ketone body formation is increased it leads to ketosis and ultimately ketoacidosis. The mobilization of adipose tissue fat and ketogenesis are far greater in diabetes than in starvation. Molecular link between diabetes and obesity Earlier I mentioned that obesity leads to type 2 diabetes mellitus. For long time the molecular link between these remained mystery despite strong clinical link.

Chronic Disease as a Public Health Issue Over the last several decades, an epidemic of "lifestyle diseases" has been developing in the United States (Pollard, 2008). These chronic conditions have become a major burden in the United States, as they lead to decreased quality of life (Healthy People 2020, 2011) and premature death and disability (Centers for Disease Control and Prevention, 2010). Another concern is the cost of treating chronic disease, estimated to account for over 75 percent of national health expenditures (Centers for Disease Control and Prevention, 2010). Furthermore, although chronic disease was once thought to be a problem of older age groups, the number of working-age adults with a chronic condition has grown by 25 percent in ten years (Hoffman and Schwartz, 2008). This shift toward earlier onset adds to the economic burden of chronic disease because of illness-related loss of productivity resulting from absence from work (absenteeism) and reduced performance while at work (presenteeism). Moreover, a report released by the Milken Institute estimated that the indirect costs of these illnesses was higher than the direct health care costs to treat chronic disease (DeVol et al. The cumulative losses associated with chronic disease totaled a startling $1 trillion in 2003, whereas $277 billion was spent on direct health care (DeVol et al. Growing Interest in Wellness Programs among Employers With the increasing prevalence of chronic diseases in the working-age population, employers are concerned about their effect on the cost of employer-sponsored health coverage and productivity. Disease prevention programs aim either to prevent the onset of diseases (primary prevention) or to diagnose and treat disease at an early stage before complications occur (secondary prevention). Primary prevention addresses health-related behaviors and risk factors-for example, by encouraging a diet with lower fat and caloric content to prevent the onset of diabetes mellitus. Health promotion is related to disease prevention in that it aims at fostering better health through behavior change. A formal and universally accepted definition for workplace wellness programs has yet to emerge, and the range of benefits offered under this label is broad. Those incentives can be tied to program participation (referred to as participatory programs) or to changes in health- related standards, such as smoking or body weight (referred to as health-contingent programs (Federal Register, 2012). Additionally, workplace wellness programs and wellness incentive 3 programs as part of those might be offered directly by an employer as a benefit for all employees or as part of an employer-sponsored group health plan for participants and beneficiaries. The emergence of a workplace wellness industry in recent years now allows employers to procure ready-made programs and interventions and has contributed to the uptake of those programs, as they demonstrate favorable results. However, those positive findings have to be viewed cautiously, because they are typically derived from selected employers with strong commitments to wellness and may not generalize to other employers But the positive reports have led many employers to regard workplace wellness programs as an effective tool to contain health care costs and, thus, as a viable business strategy. In addition to employers, health insurance issuers are increasingly incorporating wellness programs into their coverage products. Role of the Patient Protection and Affordable Care Act the Affordable Care Act has numerous provisions intended to contain health care cost growth and expand health promotion and prevention activities. This study attempts to parse out this detail when possible; however the data do not always allow for this. As well, such phrases as "employer-offered" or "employer-sponsored" are used generally throughout this report; however, unless noted otherwise, these phrases should not be read to indicate whether a program is or is not part of a group health plan. This provision gives employers greater latitude in rewarding group health plan participants and beneficiaries for healthy lifestyles through wellness programs that meet certain standards. The limit, currently set at 20 percent of the cost of coverage, will increase to 30 percent in 2014, and the Secretaries of Labor, Health and Human Services, and the Treasury may increase the reward to up to 50 percent if they determine that such an increase is appropriate.
