37. Genetic compatibility between Anopheles lesteri from Korea and Anopheles paraliae from Thailand
To assess differentiation and relationships between Anopheles lesteri and Anopheles paraliae we established three and five iso-female lines of An. lesteri from Korea and An. paraliae from Thailand, respectively. These isolines were used to investigate the genetic relationships between the two taxa by crossing experiments and by comparing DNA sequences of ri

38. Efeito da saliva de Aedes aegypti sobre a diferenciação, maturação e função de células dendríticas e na proliferação de linfócitos T. / Effect of Aedes aegypti saliva on the differentiation, maturation and function of dendritic cells and on T lymphocyte proliferation.
Mosquitos são os mais importantes vetores de patógenos humanos, transmitindo um amplo espectro de doenças infecciosas emergentes e reemergentes. Nesse cenário, o mosquito Aedes aegypti está entre as espécies mais relevantes. No presente estudo investigamos as atividades do extrato de glândula salivar (EGS) desse mosquito vetor na biologia das células

39. Clinical diagnosis of hyposalivation in hospitalized patients
OBJECTIVE: The aim of this study was to evaluate the effectiveness of clinical criteria for the diagnosis of hyposalivation in hospitalized patients. MATERIAL AND METHODS: A clinical study was carried out on 145 subjects (48 males; 97 females; aged 20 to 90 years). Each subject was clinically examined, in the morning and in the afternoon, along 1 day. A focu

40. Pleomorphic adenoma with extensive squamous metaplasia and keratin cyst formations in minor salivary gland: a case report
Pleomorphic adenoma (PA), the most common salivary gland tumor, accounts for 54 to 65% of all salivary gland neoplasias and 80% of the benign salivary gland tumors. It most frequently affects the parotid gland, followed by the submandibular and the minor salivary glands. Microscopically, mucous, sebaceous, oncocytic and squamous metaplasia, sometimes with th

41. Acupuncture for the prevention of radiation-induced xerostomia in patients with head and neck cancer
The aim of this study was to evaluate the effectiveness of acupuncture in minimizing the severity of radiation-induced xerostomia in patients with head and neck cancer. A total of 24 consecutive patients receiving > 5000 cGy radiotherapy (RT) involving the major salivary glands bilaterally were assigned to either the preventive acupuncture group (PA, n = 12)

42. Rabies virus in a pregnant naturally infected southern yellow bat (Lasiurus ega)
Current knowledge on bat lyssavirus infections in their native hosts is limited and little is known about the virulence, virus dissemination and transmission among free-living insectivorous bats. The present study is a brief description of rabies virus (RABV) dissemination in tissues of a naturally infected pregnant southern yellow bat (Lasiurus ega) and its

43. Localization and function of Rhipicephalus (Boophilus) microplus vitellin-degrading cysteine endopeptidase
The tick Rhipicephalus (Boophilus) microplus is an important parasite of cattle in many areas of the tropics. Characterization of molecules involved in mechanisms such as vitellogenesis and embryo development may contribute to a better understanding of this parasite’s physiology. The vitellin-degrading cysteine endopeptidase (VTDCE) is the most active enzy

44. Caracterização do parasitismo por Ornithodoros brasiliensis (Chelicerata: Argasidae) e da toxicose induzida em humanos e animais
Ticks are blood-sucking arthropods distributed worldwide and able to parasitize almost all terrestrial vertebrate animals. Ticks are considered a great hazard for both public health and animal breeding due to their ability to transmit infectious diseases and to induce direct toxic effects leading to clinical disturbances. Ornithodoros brasiliensis, popularly

45. 5-Bromo-2’-deoxyuridine induces visible morphological alteration in the DNA puffs of the anterior salivary gland region of Bradysia hygida (Diptera, Sciaridae)
5-Bromo-2’-deoxyuridine (BrdUrd) has long been known to interfere with cell differentiation. We found that treatment ofBradysia hygida larvae with BrdUrd during DNA puff anlage formation in the polytene chromosomes of the salivary gland S1 region noticeably affects anlage morphology. However, it does not affect subsequent metamorphosis to the adult stage.

46. Bradysia hygida (Diptera, Sciaridae) presents two eukaryotic Elongation Factor 1A gene homologues: partial characterization of the eukaryotic Elongation Factor 1A-F1 gene
Elongation factor 1A is a highly conserved protein that participates in translation. We report the occurrence of two genes homologous to the eukaryotic Elongation Factor 1A in Bradysia hygida and describe the partial cloning and characterization of the B. hygida eukaryotic Elongation Factor 1A-F1 (BheEF1A-F1) gene. The pattern of BheEF1A-F1 expression in the

47. Primary culture of Rhodnius prolixus (Hemiptera: Reduviidae) salivary gland cells
In the present paper, we developed a primary culture of Rhodnius prolixus salivary gland and main salivary canal cells. Cells remained viable in culture for 30 days. Three types of cells were indentified in the salivary gland cultures, with binuclear cells being the most abundant. The supernatants of salivary cultures contained mainly 16-24 kDa proteins and

48. Anticoagulant activity in salivary gland homogenates of Thyrsopelma guianense (Diptera: Simuliidae), the primary vector of onchocerciasis in the Brazilian Amazon
In this study, anticoagulant activity was detected in salivary gland homogenates (SGHs) of Thyrsopelma guianense (Diptera: Simuliidae). The SGH yielded 1.07 μg ± 0.03 (n = 15) of total soluble protein per pair of glands. In addition, following SDS-PAGE (12.5% gel) and silver nitrate staining, 12 polypeptides with molecular weights ranging from 14-69 kDa we
