13. Estudo comparativo dos efeitos da dexametasona e do diclofenaco sódico sobre o processo reparativo de feridas induzidas no ventre lingual de ratos / Comparative study of the effects of dexamethasone and diclofenac sodium on the repair process of induced wounds in the ventral tongue of rats
Inflammation is a protective response to rid the body of the initial cause of cell damage and its consequences, but when excessive and unmodulated, may cause progressive destruction of tissue. The aim of this study is to clarify the influence of two anti-inflammatory, diclofenac sodium and dexamethasone on the inflammatory phase of tissue repair process, as

14. Efeito do plasma rico em plaquetas e da eritropoietina na regeneração do nervo ciático de ratos wistar
Injuries to the peripheral nervous system present a challenge for regenerative medicine. The study investigated the effects of platelet-rich plasma (PRP) and erythropoietin (EPO), alone or in combination, in the regeneration of peripheral nerve in rats. The work was developed in three phases using 70 rats. The first phase, evaluated the platelet concentratio

15. Bacteriophage amplification assay for detection of Listeria spp. using virucidal laser treatment
A protocol for the bacteriophage amplification technique was developed for quantitative detection of viable Listeria monocytogenes cells using the A511 listeriophage with plaque formation as the end-point assay. Laser and toluidine blue O (TBO) were employed as selective virucidal treatment for destruction of exogenous bacteriophage. Laser and TBO can bring

16. Toxicidade aguda e efeito subletal do Roundup Transorb nos testículos de mato grosso Hyphessobrycon eques (Steindachner, 1882) (Teleostei: Characidae) / Acute toxicity and sublethal effect of Roundup Transorb in testes of mato grosso Hyphessobrycon eques (Steindachner, 1882) (Teleostei: Characidae)
The toxicity of several environmental pollutants has been investigated in humans and other species. Substances contained in agrochemicals, such as herbicides, can affect the reproductive systems of male and female animals. This study aimed to determine the LC50 and sublethal effects of Roundup Transorb on the testicular morphology of mature male Hyphessobryc

17. Efeitos do laser em baixa intensidade, da terapia fotodinâmica e do azul de toluidina O na descontaminação de superfícies de implantes metálicos: estudo microscópico em subcutâneo de ratos / Effect of low intensity laser, photodynamic therapy and toluidine blue O the on decontamination of metallic implants surfaces: microscopic study in rats\ subcutaneous tissue
A peri-implantite acomete um número crescente de indivíduos e os protocolos de tratamento objetivam descontaminar as superfícies dos implantes e torná-las novamente osseointegráveis. Porém, ainda não foi estabelecido um padrão ouro de tratamento para peri-implantite. Este estudo testa o poder de descontaminação do laser em baixa intensidade (LBI),

20. Mastócitos no lobo ventral da próstata, no epidídimo e no testículo de ratos UChB (consumidores voluntários de etanol a 10%) / Mast cells in the ventral prostate, epididymis and testis of UchB - ethanol preferring rats (10% v/v high ethanol voluntary intake)
Alcoholism has reached alarming proportions throughout the world, but there is little research on the inflammatory effect of ethanol in the reproductive organs. The mast cell, which is one of the main cells involved in inflammatory processes, is known to have two subtypes in rodents, connective (CTMC) and mucosal (MMC) tissue. Hence, the aim of this work is

21. AÃÃo da terapia fotodinÃmica antimicrobiana sobre biofilmes orais crescidos in vitro e in situ / The Photodynamic Antimicrobial Chemotherapy effect on in vitro and in situ biofilms
The treatment of diseases caused by oral biofilms involves mechanical removal and use of antibiotics and antiseptics which can lead to problems of bacterial resistance. Photodynamic antimicrobial chemotherapy (PACT) represents an alternative option to conventional treatment, promoting bacterial killing by photo-sensitization of microbial components. This stu

22. Analysis of nucleus activity in malpighian tubules of Diatraea saccharalis (Fabricius) (Lepidoptera: Crambidae) larvae by critical electrolyte concentration
Diatraea saccharalis (Fabricius) has cryptonephridial type Malphigian tubules (MT). This type of MT is characterized by the penetration of the distal part of the MT into the external walls of the rectum, which is usually lined with a perinephral membrane. The MT is divided into three differentiated regions: proximal, middle and distal. In this study, our obj

24. Clonagem e expressão de β-ficocianina em amostras de Escherichia coli. / Cloning and expression of β-phycocyanin in Escherichia coli strains.
C-phycocyanin (C-PC) is a water soluble pigment and is present in Arthrospira platensis. It is consisted of two subunits, α and β, with molecular masses of 16 and 17 kDa, respectively. Recently it was shown that the β subunit of C-PC Anabaena has antitumor activity. The main objectives of this study were cloning and expression the β subunit o
