No increased risk for premature births buy cheap ashwagandha on line, intrauterine growth retardation or newborn asphyxia was found buy ashwagandha 60caps lowest price, and 41 of the 45 infants were born at term order genuine ashwagandha online. Among the 12 newborns who had been exposed to zidovudine during the first trimester 60caps ashwagandha with mastercard, no malformations were reported. There were eight fetal or neonatal deaths, five in the group receiving zidovudine and three in the group given the placebo. None of these deaths was considered by the authors to be attributable to the drug. In order to determine the safety of zidovudine administered during pregnancy, Sperling et al. During the inclusion period of 1991–93, 424 eligible women were randomized to either zidovudine or placebo, and the women were followed through six months post partum, while their infants were followed through 18 months of age. Five women given zidovudine and two given placebo had either a spontaneous abortion or a stillbirth. Among the infants born live to women receiving zidovudine, 19 (9%) had major structural abnormalities and 28 (13%) had minor structural abnormalities, while among the infants born live to women given placebo the equivalent figures were 17 (8%) and 35 (17%). After birth, the children of these women were given daily doses of 8 mg/kg bw zidovudine and/or 4 mg/kg bw lamivudine for an average of 5. All of these children had abnormal mitochondrial oxidative phosphorylation, and three had no other clinical symptoms (Blanche et al. There were no significant differences between children exposed to zidovudine (122) and those who received placebo (112) with respect to weight, height, head circumference or cognitive development. Erythroid progenitor cells from all fetal and neonatal sources were more sensitive to zidovudine than those from the bone marrow of adult women (Shah et al. Exposure to the two higher doses was reported to reduce blastocyst formation (Toltzis et al. This study was replicated with two-cell embryos in the same laboratory, with the same result (Toltzis et al. At the highest concentration, zidovudine was reported to produce a 40% incidence of abnormal embryos (Klug et al. In a 14-week study of reproductive toxicity in 10 B6C3F1 mice dosed by gavage with 0, 100, 800 or 2000 mg/kg bw zidovudine, no treatment-related effects were found on spermatid or epididymal spermatozoal parameters in males or oestrone cycle characteristics in females (National Toxicology Program, 1999). Zidovudine treatment at both doses caused decreased sperm motility and reduced the number of pregnant mice per group. In pregnant dams, the average numbers of corpora lutea and implantations per litter were not affected by treatment, but the number of live fetuses per litter was decreased and the average number of early and/or late deaths increased. In a separate study of the same design, zidovudine at doses of 100, 200 or 400 mg/kg bw given to pregnant mice decreased body-weight gain, reportedly due to reduced litter sizes, increased the number of resorptions and reduced the fetal weights per litter. No statistically significant increase in the number of litters or fetuses with gross external alterations was reported, and no statistically significant effect on sperm motility was observed (National Institute of Environmental Health Sciences, 1999). Pregnant transgenic mice carrying the Moloney murine leukaemia virus in the germ line were treated with zidovudine dissolved in the drinking-water at a concen- tration of 0. Dosing began on either gestational day 10 or 19 and was continued throughout lactation and weaning. After weaning, the offspring received zidovudine directly in their drinking-water. Histopathological analyses of the offspring revealed no specific sequelae (Sharpe et al. Two of the three untreated mice but none of the nine treated animals produced offspring. Treatment with zido- vudine was reported to reduce the occurrence of pregnancy and the number of fetuses per litter and to increase the number of resorptions. No physical anomalies were noted on gross examination of surgically removed fetuses at 12–17 days of gestation (Toltzis et al. Fetuses, examined at day 13 of gestation, were reported to be smaller, with fewer fetuses per litter and decreased colony-forming ability of erythroid progenitor cells collected from fetal hepatic tissue (Gogu et al. The body weights (day 16) and water intake (days 12–14 and 14–16) of the dams at the highest dose were significantly decreased. Only two of 12 dams at this dose had viable litters, and the pups in these litters were lighter, smaller and less active than controls. Body-weight gain was similar in control and treated animals, but ventral prostate weight, seminal vesicle weight and serum testosterone concentrations were decreased and serum luteinizing hormone and prolactin concen- trations were increased as compared with controls (Sikka et al. Groups of 20 pregnant Wistar rats were treated with water or 100 mg/kg bw zido- vudine orally three times at 5-h intervals (total dose, 300 mg/kg bw) on day 10 of gestation. No adverse effects were reported on maternal body weight, food consump- tion, reproductive capacity or haematological parameters. No effects of zidovudine on the survival or growth of offspring and no treatment-related gross histopathological lesions were reported in the weanling rats. The mean concentration of zidovudine in day-10 embryonal homogenates, collected 30 min after the third dose, was 21 μg/g tissue (Greene et al. Starting at seven weeks of age, F0 generation males were dosed for 85 days before mating and afterwards, for a total of 175 days. F0 females were treated daily for 26 days before mating and throughout gestation and lactation. No consistent adverse effects were reported in the males or in the offspring of untreated females. Early embryo mortality was increased and the number of live fetuses per litter was decreased at 75 and 225 mg/kg bw zidovudine. Zidovudine-induced embryotoxicity was limited to early embryos, and no gross or histological changes were reported in the offspring (Greene et al. No consistent or dose-related effects on growth, development (including behaviour) or reproductive performance were reported (Greene et al. On day 22 of gestation, no gross structural malformations were found in the 12 litters examined (six per group). Treatment reduced the litter size and increased the weights of both male and female offspring. On postnatal days 21–22, the pups were injected subcutaneously with amphetamines (0. The locomotion response to amphetamines was increased only in female pups given zidovudine (Applewhite-Black et al. Pregnant Sprague-Dawley rats were given zidovudine by gavage in water at a dose of 0, 50, 100 or 150 mg/kg bw on days 19–22 of gestation, and individual offspring were treated by gavage on postnatal days 2–20 at the same doses. The authors concluded that perinatal exposure to zidovudine altered one aspect of behaviour—locomotion—the threshold for this effect depending on sex. Because no effects were seen on litter size or on maternal or pup weight gain, they concluded that zidovudine alters neurodevelopmental processes without producing overt toxicity (Busidan & Dow-Edwards, 1999a). In a follow-up study of 12–15 litters per group, behaviour after an intraperitoneal injection of amphetamine (0. Pregnant New Zealand white rabbits were treated orally twice daily at a 6-h interval with zidovudine in 0. Dams given 250 mg/kg bw were reported to have reduced weight gain during days 6–18 of gestation and decreased haemoglobin concentration, haematocrit and red blood cell count. The effects on fetuses included increased numbers of resorptions and decreased weights at 250 mg/kg bw. At 250 mg/kg bw, the mean peak concentration of zidovudine in maternal plasma was 92. Nine of the zidovudine-treated monkeys became pregnant and carried to term, as did seven control monkeys. The treated mothers developed asymptomatic macrocytic anaemia and showed decreased total leukocyte counts. The zidovudine-exposed infants were mildly anaemic at birth and showed deficits in growth, rooting and snouting reflexes and in the ability to fixate and follow near stimuli visually. One hundred metaphases from first-division cells from each culture of peripheral lymphocytes were scored for aberrations, mainly of the chromatid type. The mitotic index and frequency of chromosomal aberrations were measured in peripheral lymphocytes collected before initiation of drug therapy and at approximately four and 12 weeks during treatment.

There is an effective method of linear transformation of the space of the explanatory variables 60 caps ashwagandha with mastercard, allowing to obtain new regressors buy online ashwagandha, comfortable and effective in dealing with the prediction or recognition problems cheap 60caps ashwagandha otc. It is based on the transition from the initial set of correlated factors X1 buy ashwagandha 60 caps line, X2, … Xn to the new set of explanatory variables Z1, Z2, … Zn coefficients with zero covariance between: cov(Z ,i Zj) = 0, (i ≠ j). New factors (principal components) are selected so that the first principal component had the highest dispersion in the new set of variables, and the second – the dispersion, the next highest, and so on.. Thus, it becomes possible to reduce the number of explanatory variables to the first few principal components thus facilitated visualization of the original data. The method of principal components is easily implemented in a software environment R, which is controlled via the command line. For this environment, there are numerous additional modules library with open source that greatly enhance its functionality. R has great functionality, including a large range of options for data visualization. The method of principal components is well suited for market research, it allows you to create a new space of explanatory variables with zero multicollinearity, reducing the dimension of this space facilitates visualization of data. The pharmaceutical sector is an important part of the primary health system its condition depends on the overall level of the industry and the economy as a whole. However guarantee level free medical care to the patients is a problem carried out the most difficult and hardest. The availability of drugs is determined by their presence in the pharmaceutical market and economic accessibility that is to sayprice regulation and compensation of spending on medicines through compulsory health insurance. To analyze the current state of pharmaceutical care in Poland and establish a mechanism reimbursement cost of medicines. Some drugs are used to remove symptoms that are easy to identify, such as: painkillers, antipyretics, vitamins, homeopathic medicines can be bought without a prescription. Each patient is insured in Poland has the right to discount the price of the drugs. There are 4 levels of reimbursement of drugs: 100% free (bezpłatny (B) dispensed medicines used to treat severe, chronic diseases such as cancer, tuberculosis, infectious diseases, mental disorders, seizures, etc. Where the retail price is higher than the set limit for financing, the patient must pay the difference between the retail price and size limit funding. For discounted prescriptions mainly released generic drugs because their price is much lower than the original. In the case of the introduction of the first generic drug to limit the group, its price will be not more than 75% of the original drug price. At the end of patent protection, the manufacturer of the original drug should reduce the price by at least 25%, even if his group does not include any generic drag. Draws attention to the fact that the purchase of drugs can use and prescription prescribed in another country. If some medicines that prescribed in the recipe are absent, pharmacist can represcribe them for a patient, and leave the old prescription at the pharmacy. One prescription forms are allowed to issue up to 5 drugs on; the prescription valid 30 days usually. The doctor prescribes medicines in an amount such that enough for 3 months of treatment. According to statistics, the price of drugs in Poland for the last 20 years steadily increased, but still they are three times lower than in other European countries. Established, the average trade margin on drugs Poland is only 17%, and in most European countries – almost 30%. The provision of medical and pharmaceutical care for the population of Poland is in the form of compulsory social health insurance was determined. There are four compensation levels can be carried out on: the full amount (100% – chronic and prolonged) or partially (50% – treatment of the disease for 30 days, and 30% – other by defined list). Today the pharmaceutical market is undergoing significant changes occurring managerial and organizational transformation. This makes it necessary to improve the activities of retail pharmaceutical enterprises on the basis of modern management techniques with the use of marketing tools. Marketing strategy to promote the company acquire particular relevance in terms of competition for the market. The object of research is the process of formation and development of marketing activities of pharmaceutical companies in the current economic conditions. Theoretical generalization method, the method of analysis and synthesis, comparison method, statistical methods, methods of market research are used in the research process. There are one, two or multiple market segments that may be chosen by marketers of pharmaceutical company, and the options are between three broad approaches to the market: concentrated marketing, differentiated marketing and undifferentiated marketing. Products have not set the position, although market segmentations have been chosen. From this we can conclude that the decisive role in the choice of the drug plays its price. Marketing strategic planning is a useful management tool to help the company does better work and learn how to compete in the future. The components of complex pharmaceutical enterprise competitiveness factors identified. It was found that a favorable image, own brand increases the competitiveness of enterprises, attracting partners, customers, end users, increases sales volumes and facilitates the exercise of any commercial operations. Their efficacy has been documented in a number of clinical disorders, including osteoarthritis, rheumatoid arthritis, colds, flu, dysmenorrhea, dental pain and headache. Thus is of concern the fact that about 200 million patients are able to buy drugs in pharmacies without a prescription and medical supervision. During the research we used a systematic, logical, graphic methods and content analysis of the State Register of Medicinal Remedies. It was established that the considerable volume of products to the internal pharmaceutical market comes from European countries, medications of which make 45. The least amount of stock keeping units in the pharmaceutical market of Ukraine is presented by Bulgaria, Great Britain and Spain, each of which supply 2. Due to the correct formation of relationship between the end user and enterprise, products of this company may compete at a decent level of medicines-analogues. The image of the company and the high level of customer loyalty guarantee a competitive advantage on the market. Therefore, pharmaceutical companies use and attach great importance to various loyalty programs. The first one is based on loyalty as a certain type of customer behavior, resulting in long-term cooperation with the company and repeated purchases. Long-term relationship of customers and enterprise is formed during repeatedly interaction of parties. Another approach considers loyalty as customers‘ preference, formed as a result of synthesis of feelings, emotions, and thoughts about the company, product or service. Usually there are three types of loyalty: transactional (considering changes in the bp Perceptual (emphasizing subjective opinion of the consumer and evaluation of products, this type of loyalty is measured by consumer surveys) and complex (this type of loyalty includes 4 subtypes). The first subtype ―true loyalty‖ occurs when a buyer buys the medicine and really satisfied with it. The second subtype ―false loyalty‖ occurs when a consumer buys the medicine but not satisfied with it. The third subtype ―latent loyalty‖ occurs when a consumer appreciates brand but is unable to buy it, and when there is opportunity, always buy this brand. A fourth subtype ―lack of loyalty‖ when the consumer is not satisfied with the brand and does not buy it. Types loyalty are allocated on the base of the following conditions: consumer emotional attachment to the brand, insensitivity to the actions of competitors, the regularity of purchases, and the time factor. Methods of assessment of customers‘ loyalty are selected depending on investigated kind of loyalty. Most authors include to methods for assessing the loyalty: the method of "separation of needs" (the essence of the method is that the loyalty of the consumer is defined in numerical terms), the traditional approach (the basis of this method is the definition of "intent to purchase" of the certain brand just before making a purchase) and conversion model (using 4 major indicators: satisfaction with brand, alternatives, the importance of brand choice, the level of uncertainty or ambiguous attitude). It is based on two questions: "How would you recommend the company to your friends on a scale from 0 to 10? Therefore, "promoters" are a loyal customers and they would recommend the brand; "neutral" are passive customers, they generally satisfied with the company, but would not recommend and "critics" are not satisfied and they will not recommend the product. Consideration of these indicators together gives an opportunity to get a more accurate idea of customers‘ loyalty from different perspectives, and to reduce the disadvantages existing in the methods for making the correct decision. It is important to consider a customers‘ loyalty comprehensive and to conduct research in order to regulate the process. After all, it will enable to increase the number of clients and sales for pharmaceutical companies.
In addition buy ashwagandha 60 caps, the criteria for drugs selection include: drug efficacy cheap ashwagandha online mastercard, side effects buy ashwagandha 60caps on-line, cardio protective effect of the drug buy ashwagandha mastercard, the number of doses per day, the cost of the drug. Concerned parents may also begin to self-medicate, which can cause further problems, as they should start with the lowest dose of the drug to reduce the adverse side effects. Subsequently, a decision on replacement of a drug or a combination of therapies is made, depending on drug tolerability and its antihypertensive effect. Diuretics occupy the honorable first place among these agents, which in principle do not differ in anti-hypertensive action. Moreover, judging from the degree of influence on the endpoints of hypertension in young patients, risk factor was more significant than the increase in general cholesterol level. It became obvious that hypertension in adolescents should be cured as soon as possible – not only for improvement of the quality of patients‘ life, reduction of blood pressure and existing symptoms, but also for long-term prevention of cardiovascular diseases. It can be concluded that a number of studies make us look at the problem in a new way and to draw attention to the need for the diagnosis of hypertension in adolescents, taking into account the risk factors that will help to determine the prognosis and tactics. Therefore, such examination by skilled workers and the choice of drugs on the advice of the pharmacist will lead to the best results. Objective: The actual problem of atomic absorption analysis in medicine and pharmacy is the creation of multi-spectral light sources. The use of multi- element lamps eliminate the need for a change of light sources in the restructuring of the analyzer on the various elements thereby reducing the analysis time. Materials and Methods: Use as a spectral light sources, hollow cathode lamps due to the advantages of this form of discharge as the almost complete absence of the field and the low temperature of the gas in the negative glow. The discharge of the hollow cathode allows to initiate intensive and at the same time sufficiently complete spectra of neutral atoms and ions with narrow lines is almost completely free of the broadening due to the Stark and Doppler effects. Due to the peculiarities of the discharge mechanism of the hollow cathode discharge are present in the spectrum of the arc and spark lines as the main gas and cathode material. Results and discussion: Usually atomic absorption spectrometer contains multiple light sources, selectable using a stepper motor. The disadvantage of such structures is a significant increase in lamp size and partial diaframirovannie emission cathodes distant. Additionally, you must rebuild the optical system control device for the removal of various cathodes. It is proposed to use a coaxial cylindrical hollow cathode instead of the cathode for the creation of a multi-element light source for spectral analysis. Along the axis of the cathode cavity accommodate 5 -6 bars of equal length cathodes made of different materials. The diameter of the rods must be minimal, but to a certain size so that it does not lead to the heating 284 and deformation of the rods. The radius of the circle on which the rods must be located advisable to take equal to half the radius of the cathode polosti. Eto due to the fact that the bars do not extend beyond the region of negative glow that can reduce the radiation intensity. Accommodation close to the axis of the rods leads to mutual screening rods from the ions coming from the negative glow, which can also reduce the intensity of the radiation. The current density of the rod of the cylinder can exceed the current density of the order. Therefore rod sprayed more intensively than the cylinder, hence at small discharge currents will occur in the spectrum lines of the material web and the cylinder are fixed line material. Thus, a compound of one of the cylinder rods to the cathode leads to a source line in the spectrum of radiation material rod. To change the form of the spectrum is only necessary to connect to the cathode corresponding rod Conclusions: The proposed design of the light source it is possible to control the intensity of the emission spectra of different elements at a constant discharge current by applying the rod of a building. The proposed multi -element light source can be used in devices for multi-atomic absorption analysis. Economic theory, the provisions of which are used in the selection of regressors, is not perfect. So often in the econometric model includes factors that should not be there, and do not turn on the factors that must be present there. Proper specification of the econometric model indicates that • choose the right function for the relationship between the independent and dependent variables; • excluded from the model covariates insignificant and unimportant; • the model includes all relevant and significant covariates. Violation of the last of these conditions leads to very unpleasant consequences: • estimation of the regression parameters are biased and unfounded; • checking the quality of the model hypotheses and the construct confidence intervals for the parameter estimates are incorrect. The test is based on the auxiliary regression of the dependent variable on factors x1, x2 of the original model and power functions of the estimated values variable ŷ: 2 3 = 0 + 1 1 + 2 2 + 1 + 2 + ⋯ + + Further, it is necessary to check a hypothesis by the corresponding F-test: 0: 1 = 2 = ⋯ = = 0 If value of statistics is more critical, then the zero hypothesis is rejected, and the specification of model is recognized incorrect. The considered scheme of testing of the specification of econometric model is realized in many software products, in particular in the program environment R. R is distributed free of charge, and now it is the de facto standard for statistical computing. Usage: resettest(formula, power = 2:3, type = c("fitted", "regressor", "princomp"), data = list()) Arguments: A symbolic description for the model to be tested (or a fitted formula "lm" object). A vector of positive integers indicating the powers of power the variables that should be included. A string indicating whether powers of the fitted response, the regressor variables (factors are left out), or the first principal type component of the regressor matrix should be included in the extended model. The studies in theoretical immunology on the basis of mathematical models are considered nowadays as a priority direction in the investigations of complex systems in biological sciences which is supported by the European Science Foundation and the European Society of Mathematical and Theoretical Biology. Understanding of regularities in immune response provides the researchers and clinicians new powerful tools for the stimulation of the immune system and for increasing its efficiency in the struggle against antigen invasion. In this connection the construction of mathematical models of immune response to an antigen irritant is considered as the only right tactics in the cognition of the above regularities. The aim of the work is to develop the simple mathematical model of subclinical form of infectious disease on the basis of an equilibrium relation for each component that participates in an immune response (antigen, antibody, plasma cell, and degree of damage of an organ subjected to antigen attack). The mathematical model must adequate represent the immunological models based on theoretical and experimental conceptions on the defense system of organism. Indeed, in designing the simplest model of immune defense we have used the main conception of immunology: an antibody binds an antigen and forms antibody-antigen complexes. In proportion to the quantity of these complexes, plasma cells are formed in an organism in a time t which carry out the mass production of antibodies. The quantity of plasma cells forming in response to antigenic stimulation depends on the viability of the affected organ: the more severe is the damage to this organ the less is the quantity of plasma cells because of the deficiency arising that affects the immune defense activity. It is seen that many details are missing in this model; however, all the essential components of the immune defense mechanism are taken into account. The basic acting factors of an infectious disease are: 1) concentration of pathogenic multiplying antigens, V(t); 2) concentration of antibodies, F(t); 3) concentration of plasma cells, C(t); 4) relative characteristic of affected organ, m(t). So, the simple mathematical model of infectious disease is represented as the system of nonlinear differential equations: 288 dV (β γF)V dt dC ξ(m)αV(t - τ)F(t- τ)- μC (C C*) dt . Subclinical form of infectious disease is usually latent and is not connected with physiological disorder of an organism. It is usual contact of an organism with a familiar antigen, and the organism has the resources sufficient to suppress the antigen: specific immunoglobulin, lymphocytes, interferon, macrophages, and other components of the immune system. In this case the proliferating population of viruses or bacteria is suppressed by available resources and the antigen is destroyed before it reaches the concentration level that provokes noticeable immune and physiological reactions of the organism. Antigen concentration dynamics in case of subclinical form of disease The simple mathematical model of subclinical form of infectious disease, of course, is extremely approximate and requires further detailed elaboration. However, even in this form it allows one to include in the system various essential factors of infectious disease dynamics. Realization of simple mathematical model of subclinical form of infectious disease with the help of spreadsheet LibreOffice Calc allows computing the main parameters of disease and representing them graphically. This model is useful for exploration of general picture of a disease course and for explanation of some results of observations. Some theoretical results may be used in searching for effective methods of treatment. When violations of cerebral circulation the most important pathogenetic significance insufficient blood flow to the tissues of the brain in the pool stenotic or occluded artery and the failure or delay of venous outflow. Venous stasis in the brain is the most common form of venous disorders of cerebral circulation in a number of organic diseases of the brain.
