Ms A had an ongoing problem of acne and whiteheads. She had seen a dermatologist about this problem, and a number of medications to manage her acne had been tried unsuccessfully. Ms A heard about chemical peels and laser resurfacing, and thought that one of these treatments might be appropriate for her. She telephoned the medical centre to make some enquiries, and was informed that Dr B could offer chemical facial peels, but did not do laser treatment. Ms A decided to make an appointment to discuss the possibility of a chemical peel. 14 September 1999 Ms A's appointment with Dr B took place on 14 September 1999. Ms A advised me that she explained to Dr B that she had come to him for a cosmetic approach to her acne, and did not want medication because of the problems she had experienced in the past. She also advised Dr B that she had a liver problem, which certain medications may aggravate. A note in Dr B's medical records, dated 14 September 1999, states as follows: "Referred . for ?chemical peel, remove scars. Tried variety of meds for acne white heads. Fifferin caused facial hair, minomicin caused allergic reaction with itchy red palms and liver abnormality, Retinol A caused liver probs. Meds Fe tabs, nil FH. Acne face and ant chest since teenager. Whitehead and blackheads still Concerned re scarring at this point and considering a chemical peel or laser resurfacing " Dr B could not recall Ms A telling him that she wanted a cosmetic approach and not medication. He advised me that treating the cosmetic side of the problem alone would not be appropriate. Medication was necessary in conjunction with cosmetic treatment, in order to treat the underlying problem. Dr B advised me that he outlined Ms A's options for treatment, which were chemical peeling, antibiotic therapy, topical AHA creams, and Eryacne antibiotic ; cream. He advised Ms A that she also had the option of laser resurfacing but that he did not offer that treatment; if she wanted it she would need to go elsewhere. He also offered a series of micro-dermabrasion treatments. Dr B advised me that micro-dermabrasion is a new technology which is a gentler and safer option than conventional dermabrasion treatment. It entails abrading the skin surface with a device that blows aluminium oxide crystals onto the skin, while suctioning debris and dead.

HIV RNA over time in patients with high-level viral suppression 50 copies ml ; ? Second, is there evidence for ongoing productive infection in these patients after 5 years? We found that levels of HIV RNA in the plasma reached a steady state within 9 months of therapy initiation that we defined as residual viremia. Levels of residual viremia varied among patients and were predicted by pretreatment DNA levels. HIV RNA levels declined rapidly after intensification with abacavir, providing direct evidence for ongoing productive infection. Supporting evidence for a reduction in viral burden after treatment intensification was provided by studies of immune activation and HIV immune responses. These data support a model of residual replication in treated patients in which both localized activation of latently infected cells and productive infection contribute to residual replication. The variability of residual replication and correlation with viral DNA levels and residual replication could be interpreted in a number of ways. Adherence and drug levels are known to influence the antiviral effect of antiretroviral regimens 28, 34, 37 ; . Variability in these parameters among our patients could produce differing levels of residual replication, which would affect the pool of residual cellular DNA. However, these mechanisms would not explain a correlation between pretreatment proviral DNA levels and residual replication. The simplest interpretation of our data is that HIV DNA levels reflect the size of the pool of long-lived latently infected cells that determine the level of residual viremia in patients receiving chronic treatment. Cell-associated DNA is comprised of both integrated and unintegrated HIV DNA, and a substantial proportion of the HIV DNA in PBMC represents replication-defective genomes 7, 33, 42 ; . Linear unintegrated DNA is labile, and this subset of HIV DNA present before treatment is therefore unlikely to produce replication-competent virus after several years of therapy 4, 5, 48 ; . We did not directly measure integrated DNA or distinguish replication-competent from defective genomes. Thus, our interpretation that the number of latently infected lymphocytes determines residual viral replication relies on the assumption that the proportion of viral DNA consisting of integrated genomes with the capacity to sustain viral replication is relatively constant across patients. Other interpretations of our findings are also possible. Total HIV DNA measured in our patients at baseline may reflect a net susceptibility of lymphocytes to infection, a characteristic maintained even years after initiation of combination therapy and reflected in levels of residual viral replication. After an initial reduction associated with therapy initiation, HIV DNA levels, like RNA levels, did not decrease measurably over the 6 years of observation. Most of the cellular reservoir of HIV occurs in resting memory lymphocytes 7 ; , but resting nave cells have also recently been recognized as a smaller but detectable reservoir 38 ; . T lymphocytes specific for HIV are overrepresented among all HIV-infected memory T cells from untreated patients 16 ; , and the expected rapid turnover of such cells in the presence of abundant HIV antigens may in part account for the higher HIV DNA clearance rate over the first year of treatment. Once such cells are depleted and antigen is cleared, the residual infected cells might be expected to clear more slowly. Our observation of the apparent long-term stability of the pool of latently infected lymphocytes is consistent with findings reported by Douek et al.

Differing conversion rates have led some to question the usefulness of MCI as a concept.7 There remains much debate regarding where it stands as a clinical entity. There is a lack of agreement as to whether it represents a syndrome, a risk state or a diagnostic category in its own right.10 Some authors suggest that in fact MCI is usually early Alzheimer's disease.11 In other areas of medicine, identification of pre-disease states has led to effective prevention or early treatment strategies. For example, identifying people with impaired glucose tolerance can reduce the rate of progression to type 2 diabetes.12 Similarly, people with MCI could also be seen as a target group for prevention or early intervention strategies. Some studies have suggested that early initiation of cholinesterase inhibitor therapy donepezil ; may delay the onset of dementia in patients with MCI.13, 14 However, a recent Cochrane review concluded that at present there is insufficient evidence that the use of donepezil for patients with MCI improves cognitive function or delays progression to Alzheimer's disease.15 Studies using vitamin E have also to date shown no benefits.14 It is likely that treatments targeted at reducing cerebral plaques and tangles rather than those targeting neurotransmitters may be more effective. Agents are being developed for the treatment of Alzheimer's disease that are designed to prevent the accumulation of plaques and tangles or to disaggregate them once they are present. Use of positron emission tomography PET ; scanning with markers for amyloid and tau proteins may potentially be useful in identifying patterns of amyloid plaques and tangles. It has been suggested that this form of PET scanning and eldepryl.
BACKGROUND AND PURPOSE OF STUDY Inclusion Criteria The COMET Carvedilol or Metoprolol European Trial ; Trial1 was a superiority trial designed to compare clinical outcomes in chronic heart failure CHF ; patients treated with Carvedilol or Metoprolol. Although both classed as Beta-blockers, the two drugs have differing pharmacologic modes of action. Metoprolol tartrate the study formulation ; is a Beta-1 specific blocking agent. Carvedilol has a blocking action at both the Beta-1 and Beta-2 receptors as well as alpha-adrenergic receptors. Both Metoprolol and Carvedilol have previously demonstrated significant clinical benefit in patients with CHF in randomized controlled trials. Metoprolol significantly reduced all-cause mortality by 34% and the risk of death or hospitalization by 19% the primary endpoints ; in a large n 3991 ; double-blind, randomized, placebo-controlled study [the Metoprolol CR XL Randomized Intervention Trial in Congestive Heart Failure MERIT-HF ; 2 involving patients with NYHA class IIIV heart failure 3.4% of Metoprolol recipients and 3.8% of placebo recipients had NYHA class IV heart failure. Carvediolol's clinical benefit was demonstrated in the Carvedilol Prospective Randomized Cumulative Survival COPERNICUS ; 3 trial. This was a large n 2289 ; , multicentre, double-blind, randomized trial involving clinically euvolemic patients with severe heart failure defined as the presence of dyspnoea or fatigue at rest or with minimal exertion for 2 months and an LVEF of 25%, despite treatment with diuretics and an ACE inhibitor or angiotensin II receptor antagonist ; . The COMET trial1 was a multicenter, double-blind, parallelgroup study designed to compare the effects of nonselective blockade of the 1 2 1-adrenergic receptors with Carvedilol to those of selective 1-blockade with Metoprolol tartrate in 3029 patients with chronic HF New York Heart Association Class II-IV HF; an LV ejection fraction 35%; optimally treated with diuretics and angiotensin-converting enzyme inhibitors ; . The co-primary endpoints were all-cause mortality and the composite of all-cause mortality or all-cause hospital admission. In comparing these two agents, the COMET investigators sought to assess whether the addition of 2 1blockade with Carvedilol could demonstrate any incremental clinical advantages compared to 1-blockade alone. STUDY DESIGN March 26, 2004 To qualify for enrollment subjects with moderate or severe chronic heart failure NYHA IIIV ; were required to meet the criteria below: Subjects were on stable treatment with diuretics at a daily dose of furosemide 40 mg or equivalent bumetanide 1 mg; torasemide 10 mg; hydrochlorothiazide 100 mg; bendroflumethiazide 10 mg ; for at least 2 weeks prior to randomization. Subjects were on an ACE-inhibitor for at least 4 weeks, unless there is a contraindication. Digitalis and or vasodilators were allowed at the discretion of the physician. Left ventricular ejection fraction must be 0.35 using echocardiography, radionuclide ventriculography or contrast ventriculography. If ejection fraction was not determined then left ventricular end diastolic diameter 6.0 cm and a fractional shortening 20% as measured by echocardiography could also qualify patients. At least one hospitalization for a cardiovascular reason should have taken place during the last 2 years. Written informed consent was obtained. Exclusion criteria Relating to cardiovascular disease Recent change of heart failure therapy defined as the introduction of a new class of drug for heart failure treatment within 2 weeks prior to randomization. Treatment with oral - or -adrenergic blockers within the previous 2 weeks prior to randomization. Requirement for intravenous inotropic therapy. Current treatment with calcium channel blockers of the diltiazem or verapamil class. Current treatment with amiodarone 200 mg per day. Unstable angina within the last 2 months. Myocardial infarction within 2 months prior to the study. Cardiac surgery or angioplasty within 2 months prior to the study. Uncontrolled hypertension systolic BP 170 mmHg or diastolic BP 105 mmHg ; . Haemodynamically significant valvular disease. Symptomatic and sustained ventricular arrhythmias within the last 2 months not adequately treated with antiarrhythmic drugs or implantation of a defibrillator.

Turning then to the cardiovascular mortality in the NDA database for Celebrex, the comparisons here in the information that we had are against placebo, Celebrex itself and the NSAID comparators in two different ways. They don't differ that much; there was a slightly different definition. Then also in the long-term open- label studies. You can see that there were not many events. When you do the math here and divide it using the patient-years to get an estimate of the crude mortality rate, you can see the highest number comes out here for the NSAID comparators in both situations. It also is higher than what was found when looking at the all known cardiac deaths in the long-term openlabel arthritis experience. So, there didn't appear to be any large signals when looking at this particular outcome. Turning then to serious adverse cardiac and renal events, I have again here the columns of placebo, differing doses of celecoxib and the NSAID comparators. When you look at these events overall there were no important differences. In fact, they looked worse for the NSAID comparators and the placebo looked roughly equivalent to celecoxib. When you look at some of the individual events, and let me see if I can point to the particular events that have been discussed so far today, heart failure for example, there didn't appear to be any major differences between celecoxib and placebo; myocardial infarction, again there appeared to be no important differences between all the groups. So, looking at this data in summary, there didn't appear to be any major clear signals that distinguished celecoxib as it appeared in the NDA database from.

Cardiac tamponade, for which elders are at increased risk. If your patient has reported dizziness or syncope it may be due to postural orthostatic ; hypotension. Take orthostatic vital signs by measuring blood pressure and pulse with the patient lying and standing. A 20-point difference in any reading suggests dehydration, poorly controlled hypertension, decreased vascular tone, cerebrovascular disease, or aortic disease. Next, assess bilateral peripheral pulses. Count the radial pulse for one minute, noting the rate, rhythm, and amplitude. Look for pulsus alternans regular rhythm with alternating amplitude ; , suggesting left heart failure and pulsus paradoxus reduced pulse amplitude on inspiration ; , suggesting constrictive pericardial disease. Now measure the other radial pulse and compare it with the first. Bilaterally assess the other peripheral pulses brachial, femoral, popliteal, posterior tibial, and dorsalis pedis ; as well. Differing bilateral pulses may indicate enlarged ventricles or arterial blockage. Pulse amplitude is documented using this scale: 0, absent; + 1, markedly impaired; + 2, moderately impaired; + 3, slightly impaired; and + 4, normal. If an extremity is cool, painful, or mottled and no pulse is palpable, try using a Doppler probe to obtain the pulse. If you are still unable to obtain a pulse, alert the physician to the possibility of an obstruction or occlusion. Because of their proximity to the heart, the carotid arteries can provide important information about cardiac function. Gently palpate one carotid artery at a time, medial to the sternomastoid muscle in the neck. To prevent vagal stimulation, avoid compressing the carotid sinus located high in the neck. Don't palpate carotid pulses if the patient has a history of carotid disease, thrills, or bruits. If you feel a thrill it feels like a purring cat ; , listen to the area with the bell of your stethoscope to see if you hear a bruit vascular murmur ; . Thrills indicate turbulent blood flow, bruits, arterial narrowing.

Therefore, the best way to exercise may be in multiple short bouts of intense exercise, which can be particularly helpful for older people. Important warning note: Sudden strenuous exercise such as snow shoveling and mowing lawns ; puts such people at risk for angina and heart attack. Activities that involve raising the arms above the head may also be risky. Patients with angina should never exercise shortly after eating. People with risk factors for heart disease should seek medical clearance and a detailed exercise prescription. And all people, including healthy individuals, should listen carefully to their bodies for signs of distress as they exercise. [Seethe Report #29, Exercise.] and reminyl.

Pharmacotherapeutic group: Adrenergics and other anti-asthmatics, ATC code: R03AK06 Invented name COPD clinical trials: Placebo-controlled clinical trials, over 6 and 12 months, have shown that regular use of invented name 50 500 micrograms improves lung function and reduces breathlessness and the use of relief medication. Over a 12 month period the risk of COPD exacerbations was reduced from 1.42 per year to 0.99 per year compared with placebo and the risk of exacerbations requiring oral corticosteroids was significantly reduced from 0.81 to 0.47 per year compared with placebo. Mechanism of action: Invented name contains salmeterol and fluticasone propionate which have differing modes of action. The respective mechanisms of action of both drugs are discussed below: Salmeterol: Salmeterol is a selective long-acting 12 hour ; beta-2-adrenoceptor agonist with a long side chain which binds to the exo-site of the receptor. Salmeterol produces a longer duration of bronchodilation, lasting for at least 12 hours, than recommended doses of conventional short-acting beta-2-agonists. Fluticasone propionate: Fluticasone propionate given by inhalation at recommended doses has a glucocorticoid antiinflammatory action within the lungs, resulting in reduced symptoms and exacerbations of asthma, without the adverse effects observed when corticosteroids are administered systemically. 5.2 Pharmacokinetic properties and selegiline.

Reduces urinary symptoms and frequency of dysuria, as well as the incidences of macrohematuria and microhematuria, regardless of tumor site when administered, intravenously or orally, concurrently with any dosage of oxazaphosphorine antineoplastic alkylating agents [1] such as ifosfamide [2], cyclophosphamide [3] or trophosphamide. It has also been used as a chemoprotective drug to reduce the nephrotoxicity of carboplatin when administered in combination therapy [4]. MESNA is used also as a mucolytic agent alone or in combinations with mucolytic therapy or with anti-inflammatory drugs [5].
An important property of the calcium antagonists is their differing tissue selectivity. For example, whereas verapamil for all practical purposes is equi-effective with respect to the myocardium, vasculature, conducting and nodal tissue, making it a broad spectrum calcium antagonist so far as the cardiovascular system is concerned Table 2 ; , nifedipine has no direct effect on the conducting and nodal tissues at concentrations which render it more effective as a vasodilator than either verapamil or diltiazem Table 2 ; . Unfortunately nifedipine retains an effect on the myocardium, although certainly the ratio between its effect on the vasculature relative to that on the myocardium favours the vascular effect Table 2 ; . Nifedipine was quickly followed by a plethora of other dihydropyridine-based antagonists, developed because of their enhanced selectivity for the vasculature relative to the myocardium, whilst having no direct clinically relevant effect on either nodal or conducting tissues. Some of these more recently developed dihydropyridine-based antagonists have pharmacological profiles which render them potentially useful for the management of problems within specific vascular beds. Nimodipine, for example, with its relative selectivity for the cerebral vasculature Table 3 ; , was developed primarily for use in the management of patients with cerebral ischaemia [10]. Nisoldipine provides another example of a dihydropyridine-based antagonist which exhibits some selectivity within the vasculature in this instance for the coronary blood vessels [9]. Thus, enhanced tissue selectivity became an important hall-mark of the "second generation" calcium antagonists and created great interest and enthusiasm, but despite this improvement one other highly significant requirement was still lacking, as indeed it was in the "first generation" antagonists. This deficiency centred around their unfavourable pharmacokinetic profiles. Perhaps unfavourable is too harsh a word to apply to this deficiency, but in terms of their clinical use it was a major limiting factor. It was the search for a potent, vascular-selective calcium antagonist with a slow onset of action and a pharmacokinetic profile which would provide prolonged effective therapy without the need for multiple dosing throughout the day which led to the development of yet another calcium antagonist, amlodipine [13]. Not surprisingly the improved pharmacokinetic profile of amlodipine was accompanied by a significant reduction [15] in the intensity and occurrence of side-effects and sinemet.
Application of Artificial Neural Network Technique in Chemical Engineering Thermodynamics Phase equilibrium of mixed solvent-electrolyte systems is of prime importance in many industrial operations like distillation, absorption, precipitation etc. Presence of electrolytes in the mixture imposes substantial effect on the phase equilibrium. The main advantage of the salt effect is its ability to eliminate or alter the azeotrope. Though thermodynamic models for vapor liquid equilibrium VLE ; of mixed solvents are quite satisfactory, difficulties are faced with the incorporation of effect of salts. Hence, a semi empirical model for the prediction of effect of electrolyte on VLE of mixed solvent was developed in the present study. Solvent-solvent interactions were modeled using previously available thermodynamic models. An interaction parameter for the effect of electrolyte on VLE was modeled semi empirically using artificial neural network ANN ; technique. A suitable descriptor for the hydrogen bonding between molecules was not available in literature. Hence an ANN model was developed for the prediction of proton affinities of compounds and radicals. These proton affinity values were used to incorporate the effect of hydrogen bonding. A large database of VLE of mixed solvent electrolyte was collected from the literature and was analyzed. Using this analysis, different descriptors for solvents and salts were chosen as inputs for the network. Operating conditions were also used as inputs. To verify the predictive capability of the model, experiments were performed for VLE of 2-propanol-toluene and NaI at atmospheric pressure. Predictive capability of the model was also checked for different cations and anions. Finally, the model was compared with previously available models, in terms of deviations and interaction parameters. Effect of cationic and anionic radii on VLE of mixed solvent electrolyte was also studied with a novel approach using molecular simulations. Sreeram K.P. Supervisor: Dr. S. S. Bhagwat Structure Property Relationship for Colour Chemicals Colour is the sensation produced in the eye when the visible light falls on our retina. Colour can be described either by reflectance curve or by absorption curve. In industrial dyestuff research, numerous coloured compounds of the same base structure are generated, synthesised, differing only in the position of substituents. The absorption spectrum of such related dyes is normally found to vary. Hence it is interesting to study how structural differences within the base dye molecule will affect the absorption spectrum. In the present work, a model was developed using Artificial Neural Network ANN ; based on the Quantitative structure property relationship QSPR ; , which predicts shift in absorption bandwidth and extinction coefficient of various dyes by correlating it with the structure of molecules. Structure of organic compound is represented with a large variety of descriptors.There are various descriptors such as constitutional descriptors, electrostatic descriptors, topological descriptors, geometrical descriptors and quantum chemical descriptors. Descriptors are chosen in such a way that they have a reliable effect on the property of interest. The dyes used for the study are N-derivatives of 4-aminoazobenzene dyes and nitrodiphenyl amine dyes which differ in the position of groups. The input parameters used are resonance constant, field constant, hammet.

The possible effects on your fetus depend on the amount and frequency of your drinking, and your fetus's genetic susceptibility and stage of development. For example, the first 3 months of pregnancy are a critical time for physical development of the fetus. Alcohol use during this time can lead to abnormal facial features and birth defects. Smoking, poor health and nutrition, use of other drugs, and having had several pregnancies also increase the chances that your use of alcohol will affect the fetus. How much alcohol is safe to drink during pregnancy? No amount of alcohol is considered safe to drink during pregnancy. An amount of alcohol or a specific time during pregnancy when it is safe to drink has not been identified. When are alcohol effects on a fetus diagnosed? A baby with severe alcohol effects fetal alcohol syndrome ; may be diagnosed at birth. Children with lesser alcohol effects may not be diagnosed until behavior or learning problems develop. Can alcohol effects on a fetus be prevented? Alcohol effects on a fetus can be prevented by not drinking during pregnancy. Even one heavy drinking episode 5 or more drinks ; during this time may harm your baby. What is the treatment for my child with alcohol effects? Your child's treatment may include educational support, social skills training, vocational training, and counseling. Resources in your community may provide support and financial help for your family.

Ers would stop and translate, " and therefore FIORE is not "primarily merely a surname." Completely lacking in the opinion is any consideration or analysis of the purpose of Section 2 e ; 4 ; and the propriety of applying the doctrine of foreign equivalents in that context. 7. In re Reebok Int'l Ltd., Serial No. 78271326 October 26, 2005 ; [not citable]. In another dubious decision regarding Section 2 e ; 4 ; , the Board reversed a surname refusal of the mark J.W. FOSTER for footwear, headwear, and clothing. Once again failing to consider the purpose behind Section 2 e ; 4 ; , the panel majority employed specious logic in reasoning that the addition of initials to the word FOSTER -- which is not primarily a surname because it has other meanings -- cannot yield a mark that is primarily merely a surname. The dissent had the better argument. 8. In re Fits Corporation KK, Serial No. 76501790 August 24, 2005 ; [not citable]. In finding LOVE PASSPORT and PASSPORT confusingly similar for perfume, the Board rejected Applicant's sensible argument regarding the differing connotations of the marks, and instead embraced the PTO's position, offering a stale and unconvincing analysis regarding the significance of "love" in this context, concluding that "the additional word `LOVE' merely identifies more specifically the goal or destination of the passport.

Because of these deaths, through partial support by the California State Department of Alcohol and Drug Programs, a more sensitive analytical method of detection has been developed. The laboratories, using these new methods, have now confirmed the detection of various fentanyl derivatives in body fluids of overdose victims. In addition, they have detected the fentanyls in the urine of a significant number of individuals enrolled in various Methadone and other drug treatment programs throughout California. To date they have identified ten different fentanyl derivatives in samples being sold illicitly under a variety of names such as "China White", Synthetic Heroin" and "Fentanyl.
BISPHOSPHONATE PHARMACOLOGY J R Green. Novartis Institutes for BioMedical Research, Basel, Switzerland Although the first bisphosphonate compounds BPs ; were synthesized in the mid-19th. century and have subsequently been widely used as industrial anti-scaling agents, investigations into their pharmacological properties were only initiated in the early 1960's. After more than 4 decades of research and development, BPs are now firmly established as the drugs of choice for the inhibition of elevated osteoclastic bone resorption associated with both benign and malignant bone disease. BPs are derivatives of naturally occurring pyrophosphate in which the central oxygen atom of the P-O-P motif is replaced by a carbon atom. This modification has 2 important consequences: unlike pyrophosphate, the P-C-P structure is resistant to enzymatic degradation by phosphatases, and the tetravalent carbon atom permits addition of various substituents to produce a range of compounds with differing pharmacological properties. Extensive structure activity studies have generated 3 subclasses of BPs, each with improved potency and therapeutic ratio: 1 ; simple BPs lacking a nitrogen atom, 2 ; BPs containing a single nitrogen in an aliphatic side chain, 3 ; BPs containing 1 or 2 nitrogen atoms in a heterocyclic side chain. For many years it has been known that all BPs bind strongly to mineralized bone but the precise cellular and molecular mechanism of action has remained elusive. It is now clear that, after endocytic uptake by osteoclasts, the simple BPs are metabolized to cytotoxic analogues of ATP, whereas all the nitrogen-containing compounds disrupt osteoclast function by inhibiting a key enzyme of the mevalonate pathway, farnesyl diphosphate synthase FPPS ; , and thus prevent prenylation of essential small GTPase signalling molecules. The detailed structural interaction of BPs with the active site of the FPPS target enzyme has recently been elucidated at the atomic level by X-ray crystallography. Pharmacologic profiling of BPs has been carried out in various in vitro and in vivo models of bone metabolism which are highly predictive for metabolic and malignant bone disease. Clinical trials of the latest generation of BPs have confirmed the outstanding efficacy and tolerability of these newer compounds not only for the treatment of osteoporosis and bone metastases but also as a therapy for Paget's disease of bone. IS11 BISPHOSPHONATE ACTIONS AND PAGET'S DISEASE M J Rogers, K Thompson. University of Aberdeen, Aberdeen, UK An increase in the number of active osteoclasts, causing rapid bone remodelling, is the central pathological feature of Paget's disease. Bisphosphonates, being powerful inhibitors of bone resorption, remain the treatment of choice. Enormous progress has been made over the last few years in understanding how bisphosphonate drugs act at the molecular level to inhibit osteoclasts. After targeting bone and selective internalisation by osteoclasts, nitrogen-containing bisphosphonates potently inhibit FPP synthase. Inhibition of this enzyme disrupts the flux through the mevalonate pathway, the metabolic route required for the intracellular biosynthesis of cholesterol, as well as for the synthesis of the isoprenoid lipids FPP and GGPP. The farnesyl and geranylgeranyl isoprenoid lipid groups of FPP and GGPP are required for the carboxy-terminal modification of small GTP-binding proteins such as Ras, Rho, Rac and Rabs. Modification with farnesyl or geranylgeranyl groups prenylation ; is essential for the correct localisation of small GTPases to cell membranes. Prenylated small GTPases act as molecular switches, playing key roles in intracellular signaling pathways that regulate processes fundamental to osteoclast function, including membrane ruffling, trafficking of vesicles, cytoskeletal organisation and cell survival. Inhibition of FPP synthase by.

After several washes, a pre-formed ABC reagent Vectastain; Vector Laboratories ; was conjugated to the free biotin of the secondary antibody. The antigen was visualized using the peroxidase substrate 3-amino-9-ethylcarbazole ACE ; . The samples were then counterstained with Mayer's hemalum. The sections were coverslipped with Kaiser's glycerol gelatin. To test the specificity of the antibody, control sections were stained simultaneously following the same procedure, with the exception that the primary antibody was omitted. All sections were assessed for localization and intensity of specific immunoreactivity on a semiquantitative scale of by two blinded observers Table 2.
