A presente invenção se refere ao uso de compostos derivados ftalimídicos e/ou sulfonamídicos com propriedades doadoras de óxido nítrico, os quais apresentam importantes atividades no aumento da expressão gênica de gama globina e atividades antiinflamatórias e analgésicas, potenciais ao tratamento de doenças hematológicas em que há a necessidade de diminuição dos níveis do fator TNF-<244> e a necessidade de uma fonte exógena de óxido nítrico. Mais particularmente, a presente invenção descreve o uso de tais derivados ftalimídicos e/ou sulfonamídicos para o tratamento de anemia falciforme. A invenção também apresenta como característica inovadora, a descrição de novos derivados ftalimídicos funcionalizados, desenhados a partir dos protótipos talidomida e hidroxiuréia e planejados racionalmente através da estratégia de hibridação molecular para o tratamento das doenças citadas. A invenção apresenta ainda um novo método de obtenção de um derivado sulfonamídico específico que pode ser utilizado na preparação de um medicamento para tratamento de doenças em que há a necessidade de diminuição dos níveis do fator TNF-<244> e a necessidade de uma fonte exógena de óxido nítrico.

Preparation and use of phthalimide and/or sulphonamide derivatives with nitric oxide donor properties, having activities in increasing gamma-globin gene expression and anti-inflammatory and analgesic activities, effective in the treatment of hematologic diseases which require reducing the TNF-[alpha] levels and an exogenous source of nitric oxide, such as sickle-cell disease. The functionalized phthalimide derivatives are designed from the prototypes thalidomide and hydroxyurea.

In this paper we show how to obtain efficient designs of experiments for fitting Michaelis-Menten and Hill equations useful in chemical studies. The search of exact D-optimal designs by using local and pseudo-Bayesian approaches is considered. Optimal designs were compared to those commonly used in practice using an efficiency measure and theoretical standard errors of the kinetic parameter estimates. In conclusion, the D-optimal designs based on the Hill equation proved efficient for estimating the parameters of both models. Furthermore, these are promising with respect to practical issues, allowing efficient estimation as well as goodness-of-fit tests and comparisons between some kinetic models.

Brazil has the fourth largest horse herd in the world, this is due the recognition and appreciation that the different equestrian games are having within the country. Injuries of the tendon, especially in the digital flexor tendon, are the main cause of athletic life reduction among horses. The treatment of tendinitis in horses seeks full recovery of the damage tissue reestablishing the function previously lost, however conventional treatments have proven to be ineffective when considered the quality of the scar tissue and the rate of recurrence. Due to this, the use of adult stem cells to the treatment of musculoskeletal injuries of horses has been studied for some time. This method of treatment consists of aspiration of bone marrow or removal of subcutaneous fat tissue and implantation of these cells in the injured tissue. After obtaining the bone marrow the implantation can be performed with total bone marrow, with the mononuclear fraction of MSC or with cells cultured in vitro. From the fat tissue is used the stromal vascular fraction obtained by collagenase digestion, followed or not by cell culture. According to some studies, cell therapy with material obtained from bone marrow or adipose tissue has shown to be viable, given that these materials are abundant in repair components such as mesenchymal stem cells (MSC), growth factors and other components of the collagen matrix. Several studies using both types of cells have shown great potential and promising clinical results. However, knowledge of the biology and characterization of these cells remain largely unknown, and therefore is needed great care and caution when using stem cells for the treatment of musculoskeletal disorders in horses

The process of environmental impact assessment (EIA), in the extent of previous environmental studies, has as one of its functions to provide subsidies to the actions of environmental managment of enterprises. However, the proper estructuring of programs that allows to support this managment does not often occurs. This research sought as one of its objectives to evaluate in which extent the process of EIA can be a subsidie for the EMS, providing basic elements of this system. In addition, more specifically, the research had as one of its objetives the development of subsidies for the implantation of an Environmental Managment System (EMS), based on the model of ISO 14001 (2004), for a sewage treatment plant yet to be constructed in the city of President Venceslau / SP. In order to achieve theses objetives, a discussion was held based on the evaluation of environmental studies available in the library of Cetesb / SMA. Still, for the elaboration of subsidies for the EMS of the treatment plant, the research was focused on the structuring of environmental management program, based on the information contained in its Preliminary Environmental Report (PER). The research had as one of its products, the development of subsidies for the planning and control of the environmental aspects and impacts and for the environmental program of the enterprise, based on the use of environmental indicators. It was concluded, based on the results that, in general, the previous environmental studies analyzed showed little emphasis on the phase of development of structured environmental programs that offer guidelines to achieve the desired results for the environmental performance of the company.

The intervertebral disc diseases have a high casuistic in clinical routines veterinary among dogs. These conditions can cause pain, paresis or paralysis of limbs depending on the degree of injury. Clinical signs are not limited to the intervertebral disc, other anatomical parts are included. In conventional medicine, treatment may be surgical or clinical, by the use of corticosteroids with muscle relaxants. Acupuncture was an alternative to treating these diseases due to its anti-inflammatory and analgesic effects. Although there are few studies for the treatment of discopathies, acupuncture triggers the release of substances such as dynorphins, beta-endorphins and serotonin, among others; that act inhibiting somatic and visceral pain. Electroacupuncture is used to potentiate the effects of acupuncture. It can be performed with different frequencies according to the clinical evolution. However there are different opinions related to the greater efficacy in relation to acupuncture. The restraint and monitoring of the treated animal are important factors for its recovery. The association between acupuncture and conventional treatment (surgical or clinical) achieved better results than acupuncture alone. This proves that acupuncture can be considered an option in order to minimize the complications of surgery or assist in patient recovery

A técnica radioterápica Total Skin Irradiation (TSI), utilizada para tratamento de Micose Fungóide e doenças similares, apresenta grande complexidade na sua dosimetria e implementação nos Serviços de Radioterapia. No SUS – Sistema Único de Saúde - do Brasil, só há esse tratamento no Serviço de Radioterapia do Hospital das Clínicas da UNICAMP (Campinas) e no Instituto Nacional do Câncer (INCA) (Rio de Janeiro). O objetivo deste trabalho é o estudo e o desenvolvimento de um protocolo de controle de qualidade e dosimetria a ser implementado na técnica utilizada no Serviço de Radioterapia do Hospital de Clínicas da Universidade Estadual de Campinas (HC - UNICAMP). Todos os estudos e análises para a elaboração do protocolo foram baseados no Report 23[1] da AAPM – American Association of Physicists in Medicine - e no TRS-398[3] da IAEA – International Atomic Energy Agency. A metodologia e os resultados obtidos apresentam-se descritos neste relatório
