A percep����o da doen��a de Alzheimer pelos estudantes da F.F.C. J��lio de Mesquita Filho da UNESP, Mar��lia

Alzheimer���s disease (AD) accounts for approximately 56% of all cases of dementia. The present study aimed to report the perception of AD by students of Physiotherapy, Speech Therapy and Occupational Therapy from Faculty of Philosophy and Science ���Julio de Mesquita Filho��� ��� UNESP ��� Mar��lia, with regard to the symptoms, diagnosis and treatment, between 2011 and 2012. The questionnaire with open and closed questions was administered to 101 students, using as a criterion for exclusion those who refused to answer the survey and / or not signed the informed consent form. After the questionnaire application, the answers have undergone quantitative analysis, checking which information and concepts about Alzheimer���s disease these students acquired during the undergraduate years. The data shows that although students have knowledge about the signs and symptoms of the disease, few mention the importance of family, the caregiver and the relationship of the disease with dependence that commonly reaches this population.

Conectando-c: a influ��ncia da internet na vida dos portadores de Hepatite C

Hepatitis C is a disease that affects approximately four million Brazilians. It is a rare disease with symptoms but with a treatment that involves marked secondary effects. The silence of their symptoms, however, socially projected, build the social imaginary figures that send feelings and prejudices, being born therefore the social stigma. This situation fundamentally affects the welfare of their subjects. In this aspect, this research traces a parallel between the situation experienced by patients with hepatitis C and the use for these individuals from the World Wide Web and its interactive tools on overcoming limits the disease and in the reconstruction of their social identities.

Epidemiological profile of hepatitis C virus infection in patients from west region of Minas Gerais State, Brazil

Hepatitis C virus (HCV) is a serious public health problem and is the leading cause of liver transplantation due to cirrhosis and hepatocellular carcinoma. In Brazil, it is estimated that there are approximately 2 to 3 million HCV chronic carriers. Few data regarding HCV infection are available in West region of Minas Gerais State. Due to the absence of an effective vaccine against this important human pathogen and the high costs of antiviral treatment, it is important to conduct epidemiological studies with the purpose of carry out the planning and implementation of measures to prevent hepatitis C in different populations. Therefore, the aim of this study is to describe the epidemiological aspects of HCV patients from West region of Minas Gerais State, Brazil. Sociodemographic data and risk factors for HCV infection were determined from 74 HCV patients from Uberlandia city (Minas Gerais State). Reactive anti-HCV sera samples were submitted to HCV RNA and genotype detection. Most of individuals were male (63.5%) with mean age of 51 years and presenting low socioeconomic status. HCV genotype was determined among 40 samples and the frequencies were: genotype 2 (45%), 1 (37.5%) and 3 (17.5%). Hepatitis C virus (HCV) infection was common among male and low socioeconomic status individuals.

Homogenous demineralized dentin matrix and platelet-rich plasma for bone tissue engineering in cranioplasty of diabetic rabbits: biochemical, radiographic, and histological analysis

This study evaluated the effects of homogenous demineralized dentin matrix (HDDM) slices and platelet-rich plasma (PRP) in surgical defects created in the parietal bones of alloxan-induced diabetic rabbits, treated with a guided bone regeneration technique. Biochemical, radiographic, and histological analyses were performed. Sixty adult New Zealand rabbits were divided into five groups of 12: normoglycaemic (control, C), diabetic (D), diabetic with a PTFE membrane (DM), diabetic with a PTFE membrane and HDDM slices (DM-HDDM), and diabetic with PTFE membrane and PRP (DM-PRP). The quantity and quality of bone mass was greatest in the DM-HDDM group (respective radiographic and histological analyses: at 15 days, 71.70��16.50 and 50.80��1.52; 30 days, 62.73��16.51 and 54.20��1.23; 60 days, 63.03��11.04 and 59.91��3.32; 90 days, 103.60��24.86 and 78.99��1.34), followed by the DM-PRP group (respective radiographic and histological analyses: at 15 days 23.00��2.74 and 20.66��7.45; 30 days 31.92��6.06 and 25.31��5.59; 60 days 25.29��16.30 and 46.73��2.07; 90 days 38.10��14.04 and 53.38��9.20). PRP greatly enhanced vascularization during the bone repair process. Abnormal calcium metabolism was statistically significant in the DM-PRP group (P<0.001) for all four time intervals studied, especially when compared to the DM-HDDM group. Alkaline phosphatase activity was significantly higher in the DM-HDDM group (P<0.001) in comparison to the C, D, and DM-PRP groups, confirming the findings of intense osteoblastic activity and increased bone mineralization. Thus, HDDM promoted superior bone architectural microstructure in bone defects in diabetic rabbits due to its effective osteoinductive and osteoconductive activity, whereas PRP stimulated angiogenesis and red bone marrow formation.

Higher algebras and mesonic spectrum in two-dimensional QCD

We construct composite operators in two-dimensional bosonized QCD, which obey a W��� algebra, and discuss their relation to analogous objects recently obtained in the fermionic language. A complex algebraic structure is unravelled, supporting the idea that the model is integrable. For singlets we find a mass spectrum obeying the Regge behavior.

An introductory informatics theoretical framework, based on an integrable lattice model using quantized function algebras, for studying DNA-ionized gas interaction system

Usually we observe that Bio-physical systems or Bio-chemical systems are many a time based on nanoscale phenomenon in different host environments, which involve many particles can often not be solved explicitly. Instead a physicist, biologist or a chemist has to rely either on approximate or numerical methods. For a certain type of systems, called integrable in nature, there exist particular mathematical structures and symmetries which facilitate the exact and explicit description. Most integrable systems, we come across are low-dimensional, for instance, a one-dimensional chain of coupled atoms in DNA molecular system with a particular direction or exist as a vector in the environment. This theoretical research paper aims at bringing one of the pioneering ���Reaction-Diffusion��� aspects of the DNA-plasma material system based on an integrable lattice model approach utilizing quantized functional algebras, to disseminate the new developments, initiate novel computational and design paradigms.
