This study investigated the protective effect of a Vitis vinifera L. grape skin extract (ACH09) on blood pressure, lipid profile, and oxidative status in spontaneously hypertensive rats (SHR). Systolic blood pressure (SBP), total cholesterol, triglyceride, and glucose levels, as well as oxidative damage and antioxidant activity in the plasma and kidney, were evaluated in four experimental groups: control Wistar rats (W-C) and SHR-C that received water, and Wistar rats and SHR treated with ACH09 (200 mg/kg/d) in drinking water for 12 weeks (W-ACH09 and SHR-ACH09, respectively). SBP increased in the SHR group compared with the W groups and the treatment with ACH09 prevented the development of hypertension. Plasma triglyceride and total cholesterol levels increased in SHR compared with W-C rats; these changes prevented by treatment with ACH09. Glucose levels did not differ between the groups. The SHR group had increased oxidative damage in plasma, as expressed by 2-thiobarbituric acid reactive substances (TBARS) levels, and this prevented by ACH09. Levels of TBARS in the kidneys were lower in the SHR-ACH09 group than in the SHR-C group. Further, ACH09 increased the superoxide dismutase activity in both the plasma and kidneys of both SHR and Wistar rats. These results suggest that ACH09 is protective against disruption of blood pressures, oxidant status, and lipid profile in SHR, and provide important evidence on the benefits of ACH09 on hypertension and associated cardiovascular complications.

Populations of plant-parasitic nematodes were evaluated in soil and root samples from areas planted with passion fruit, or covered with adjacent native cerrado vegetation, in five different cropping regions of the Brazilian Federal District. From July 2007 to January 2008, twenty samples had been collected in five Rural Centers (N$\acute{u}$cleo Rural-NR) planted with passion fruit. In five sites, samples were also collected in native cerrado vegetation. Specimens of nine genera of plant-parasitic nematodes (Meloidogyne, Helicotylenchus, Rotylenchulus, Scutellonema, Pratylenchus, Paratylenchus, Hemicycliophora, Xiphinema and Criconemoides) were found in the present survey. Important nematode pathogens, such as Rotylenchulus reniformis and Meloidogyne spp. were observed in the passion fruit plantations throughout five major producing regions of the Brazilian Federal District.

Purpose: This study aimed to assess texture analysis (TA) of cone-beam computed tomography (CBCT) images as a quantitative tool for the differential diagnosis of odontogenic and non-odontogenic maxillary sinusitis (OS and NOS, respectively). Materials and Methods: CBCT images of 40 patients diagnosed with OS (N = 20) and NOS (N = 20) were evaluated. The gray level co-occurrence (GLCM) matrix parameters, and gray level run length matrix texture (GLRLM) parameters were extracted using manually placed regions of interest on lesion images. Seven texture parameters were calculated using GLCM and 4 parameters using GLRLM. The Mann-Whitney test was used for comparisons between the groups, and the Levene test was performed to confirm the homogeneity of variance (α = 5%). Results: The results showed statistically significant differences (P<0.05) between the OS and NOS patients regarding 3 TA parameters. NOS patients presented higher values for contrast, while OS patients presented higher values for correlation and inverse difference moment. Greater textural homogeneity was observed in the OS patients than in the NOS patients, with statistically significant differences in standard deviations between the groups for correlation, sum of squares, sum of entropy, and entropy. Conclusion: TA enabled quantitative differentiation between OS and NOS on CBCT images by using the parameters of contrast, correlation, and inverse difference moment.

Background: Canine herpesvirus type 1 (CaHV-1) infects dogs and is associated with neonatal deaths and reproductive, ocular, neurological, and respiratory problems. In Brazil, reports of CaHV-1 have been restricted to the southeast and south regions, particularly in municipalities in the state of Rio Grande do Sul. Objectives: To assess the presence and variability of CaHV-1 in canine populations in the state of Pará, North Brazil. Methods: Biological samples from 159 dogs from 4 municipalities in the State of Pará were evaluated using polymerase chain reaction and phylogenetic analyses, with the target being the viral enzyme, thymidine kinase. Results: CaHV-1 was detected in 13 dogs (8.2%), with 2 animals being from the municipality of Santa Bárbara do Pará, 8 from Algodoal Island, 2 from Salinópolis, and one from Capanema. The study sequences revealed 100% identity among themselves and 64% to 100% identity with the other nucleotide sequences from Australia, Brazil, United Kingdom, and United States, including 100% identity with the 2002 isolate from Australia. The 1996 isolate from France was grouped in a branch that was different from the sequence of this study. Conclusions: This study presents the first molecular detection of CaHV-1 in dogs from the Amazon region in northern Brazil. The nucleotide identity between the strains and cytosine insertion in the sequences isolated in this study suggests at least 2 strains of CaHV-1 circulating in Brazil (Pará and BTU-1).

A biodiesel process in a packed bed reactor was used as a model system to show the strong dependenceof the reactor behavior on the developing of chemical environment within the reactor. Ethanolysis runsof babassu and macaw palm oils were carried out in a solvent-free system using Burkholderia cepacialipase immobilized on silica–PVA matrix. The best performance was found for the reactor running onmacaw palm oil, which resulted in a stable operating system and an average yield of 87.6 ± 2.5%. Thisstrategy also gave high biocatalyst operational stability, revealing a half-life of 478 h.

Insulinoma is a very rare neuroendocrine tumor that causes hypoglycemia and neuroglycopenic symptoms. Initial diagnostic imaging tests include ultrasound, computed tomography and magnetic resonance imaging. In most cases surgical treatment of insulinoma results in complete recovery. In this paper we described a rare case of insulinoma misdiagnosed with schizophrenia.

Purpose: Lateral pterygoid muscle (LPM) plays an important role in jaw movement and has been implicated in Temporomandibular disorders (TMDs). Migraine has been described as a common symptom in patients with TMDs and may be related to muscle hyperactivity. This study aimed to compare LPM volume in individuals with and without migraine, using segmentation of the LPM in magnetic resonance (MR) imaging of the TMJ. Materials and Methods: Twenty patients with migraine and 20 volunteers without migraine underwent a clinical examination of the TMJ, according to the Research Diagnostic Criteria for TMDs. MR imaging was performed and the LPM was segmented using the ITK-SNAP 1.4.1 software, which calculates the volume of each segmented structure in voxels per cubic millimeter. The chi-squared test and the Fisher’s exact test were used to relate the TMD variables obtained from the MR images and clinical examinations to the presence of migraine. Logistic binary regression was used to determine the importance of each factor for predicting the presence of a migraine headache. Results: Patients with TMDs and migraine tended to have hypertrophy of the LPM (58.7%). In addition, abnormal mandibular movements (61.2%) and disc displacement (70.0%) were found to be the most common signs in patients with TMDs and migraine. Conclusion: In patients with TMDs and simultaneous migraine, the LPM tends to be hypertrophic. LPM segmentation on MR imaging may be an alternative method to study this muscle in such patients because the hypertrophic LPM is not always palpable.

Purpose: The aim of this study was to evaluate changes in the trabecular bone through texture analysis and compare the texture analysis characteristics of different areas in patients with medication-related osteonecrosis of the jaw (MRONJ). Materials and Methods: Cone-beam computed tomographic images of 16 patients diagnosed with MRONJ were used. In sagittal images, 3 regions were chosen: active osteonecrosis (AO); intermediate tissue (IT), which presented a zone of apparently healthy tissue adjacent to the AO area; and healthy bone tissue (HT) (control area). Texture analysis was performed evaluating 7 parameters: secondary angular momentum, contrast, correlation, sum of squares, inverse moment of difference, sum of entropies, and entropy. Data were analyzed using the Kruskal-Wallis test with a significance level of 5%. Results: Comparing the areas of AO, IT, and HT, significant differences (P<0.05) were observed. The IT and AO area images showed higher values for parameters such as contrast, entropy, and secondary angular momentum than the HT area, indicating greater disorder in these tissues. Conclusion: Through texture analysis, changes in the bone pattern could be observed in areas of osteonecrosis. The texture analysis demonstrated that areas visually identified and classified as IT still had necrotic tissue, thereby increasing the accuracy of delimiting the real extension of MRONJ.
