1. Density of mast cells and intensity of pruritus in psoriasis vulgaris: a cross sectional study
Abstract: BACKGROUND: Psoriasis is a chronic and prevalent disease, and the associated pruritus is a common, difficult-to-control symptom. The mediators involved in psoriatic pruritus have not been fully established. OBJECTIVE: To evaluate associations between the number of mast cells in psoriatic lesions and the intensity of pruritus. METHODS: 29 patient

2. Interaction of antimicrobial peptide Plantaricin149a and four analogs with lipid bilayers and bacterial membranes
The amidated analog of Plantaricin149, an antimicrobial peptide from Lactobacillus plantarum NRIC 149, directly interacts with negatively charged liposomes and bacterial membranes, leading to their lysis. In this study, four Pln149-analogs were synthesized with different hydrophobic groups at their N-terminus with the goal of evaluating the effect of the mod

3. Comparison of two peptide radiotracers for prostate carcinoma targeting
OBJECTIVES: Scintigraphy is generally not the first choice treatment for prostate cancer, although successful studies using bombesin analog radiopeptides have been performed. Recently, a novel peptide obtained using a phage display library demonstrated an affinity for prostate tumor cells. The aim of this study was to compare the use of a bombesin analog to

4. O papel das quimiocinas CCL3, CCL2 e seus receptores na movimentação dentária ortodôntica
Orthodontic tooth movement (OTM) is achieved by the remodeling of periodontal ligament (PDL) and alveolar bone in response to mechanical loading. This process is regulated by pro-inflammatory mediators, such as cytokines and chemokines. CCL2, CCL3 and CCL5 are chemokines involved in osteoclastogenesis and are upregulated in periodontium after mechanical load

5. EIXO ECA2/ANG-(1-7)/MAS E SUA REGULAÇÃO NO PROCESSO DE OVULAÇÃO / ECA2/ANG-(1-7)/MAS AXIS AND ITS REGULATION DURING THE PROCESS OF OVULATION
The Renin-Angiotensin System (RAS) has been associated with various reproductive functions, including the ovulatory cascade. Unlike angiotensin II (AngII), the role of angiotensin-(1-7) [Ang-(1-7)] has not been characterized in the ovary of mono-ovulatory species. The objective of this study was to determine the Ang-(1-7) concentration in follicular fluid an

6. A self-checking scheme to mitigate single event upset effects in SRAM-based FPAAs
In this work the problem of Single Event Upset (SEU) is considered in a recent analog technology: The Field Programmable Analog Arrays (FPAAs). Some FPAA models are based on SRAM memory cells to implement the user programmability, which makes this kind of device vulnerable to SEU when employed in applications susceptible to the incidence of radiation. In the

7. Metodologia para descrição de células analógicas como IP
This work proposes a methodology for the description of analog and mixed-signal VLSI cells as intellectual property (IP) blocks. The methodology was applied on analog/mixed-signal circuitry blocks - a voltage-to-current converter and an analog-to-digital converter, previously designed in CMOS technology - as study cases. Adaptations were performed in the blo

8. Identification and chromosomal localization of 9 Leishmania (L.) major loci related to resistance against two inhibitors of ergosterol biosynthesis pathway / Identificação e caracterização cromossomal de 9 loci de Leishmania (L.) major relacionados com resistência a inibidores da via de biossíntese do ergosterol
Ergosterol is an important compound responsible to maintain integrity and fluidity of Leishmania spp. membranes. Starting from an overexpression/selection method, our group has isolated nine different loci of L. (L.) major related to resistance against two inhibitors of the ergosterol biosynthesis pathway, Terbinafine (TBF) and Itraconazole (ITZ). Individual

9. Action of tubercidin a toxic purine analogue in Leishmania spp / Ação do análogo de purina tóxico tubercidina em Leishmania ssp.
Gene identification associated with drug resistance has contributed to a better understanding of the mechanism of action of anti parasitic compounds. Using transfection and over-expression selection strategy we isolated two loci related with the resistance of tubercidin (TUB), a toxic analog purine. In the first locus we identified an ortholog of the TOR gen

10. Mixed-signal analog-digital circuits design on the pre-diffused digital array using trapezoidal association of transistors
The mixed-signal and analog design on a pre-diffused array is a challenging task, given that the digital array is a linear matrix arrangement of minimum-length transistors. To surmount this drawback a specific discipline for designing analog circuits over such array is required. An important novel technique proposed is the use of TAT (Trapezoidal Association

11. Análise proteômica comparativa entre neutrófilos não ativados e ativados com PMA, um análogo do diacilglicerol
Neutrophils are the major type of leukocytes in peripheral blood and protect against fungal and bacterial infections. Directed migration in a gradient of chemotactic stimuli enables these cells to rapidly find the site of infection and destroy the invading pathogens. PMNs can exist in three different activation states, namely, resting, primed, and activated

12. Estratégias para prospecção e predição de peptídeos bioativos
Chapters one and two deal with the isolation and identification of bioactive peptides from the skin secretion of Phyllomedusa hypochondrialis. The first chapter demonstrates the use of protemic techniques, mainly mass spectrometry, for the study of bradykinin related peptides (BRPs) present in the amphibians secretion and freshly dissected skin fragments.
