Qualidade da carne de frangos da linhagem Label Rouge suplementados com minerais biocomplexados e criados em sistema alternativo / [Meat quality of Label Rouge lineage chicken supplemented with biocomplexed minerals and reared in an alternative system]

Objetivou-se avaliar a influência da suplementação com minerais biocomplexados sobre a qualidade da carne de frangos da linhagem Label Rouge, de ambos os sexos, criados em sistema alternativo. O delineamento experimental foi inteiramente ao acaso (DIC), disposto em esquema fatorial (3x2), sendo três dietas (controle; 0,50ppm de selênio; 0,40ppm de cromo) e dois sexos. Para a estabilidade lipídica, foi utilizado o DIC, disposto em esquema fatorial (3x2x2), sendo três dietas, dois sexos e dois tempos de armazenamento (zero e 12 meses). Os parâmetros avaliados no peito e na coxa foram: pH final, cor (L* - luminosidade, a* - índice de vermelho, b* - índice de amarelo, C* - índice de saturação e h* - ângulo de tonalidade), perda de peso por cozimento (PPC), força de cisalhamento (FC) e estabilidade lipídica. Além disso, foram avaliadas a proporção das formas químicas da mioglobina da coxa e a quantificação do conteúdo de selênio no peito. Não houve efeito isolado da dieta sobre os parâmetros físicos e químicos do peito e da coxa e sobre a concentração de selênio no peito. As fêmeas apresentaram médias superiores de L* (57,57), b* (10,55) e C* (10,60) do peito; e os machos de L* (55,09) da coxa. Entre os machos, as aves alimentadas com a dieta controle e com cromo expressaram valores superiores de FC da coxa em relação às suplementadas com selênio; para o tratamento com cromo, os machos apresentaram média superior de FC da coxa e, em contrapartida, para o tratamento com selênio, as fêmeas manifestaram a maior média. As amostras submetidas ao período de 12 meses de armazenamento mostraram maiores valores de substâncias reativas ao ácido tiobarbitúrico (TBARS) em ambos os cortes. A suplementação com cromo e selênio biocomplexados não provocou alterações na qualidade da carne; as fêmeas demonstraram melhores atributos de qualidade da carne.(AU)

The objective of the present study was to evaluate the influence of the supplementation with biocomplexed minerals on the quality of the meat of label Rouge lineage chicken, of both genders, reared in an alternative system. The experimental design was completely randomized (CRD) in a factorial scheme (3x2), with three diets (control; 0.50ppm of selenium; 0.40ppm of chromium) and two genders. For lipid stability, the CRD arranged in a factorial scheme (3x2x2) was used, being three diets, two genders and two storage times (0 and 12 months). The parameters evaluated in the breast and in the thigh were: final pH, color (L* - luminosity, a* - red index, b* - yellow index, C* - saturation index and h* - tonality angle), weight loss per cooking (WLC), shear force (SF) and lipid stability. In addition, we evaluated the proportion of chemical forms of myoglobin of the thigh and the quantification of selenium content in the breast. There was no isolated effect of diet on the physical and chemical parameters of the breast and thigh and selenium concentration in the breast. Females had higher mean values of L* (57.57), b* (10.55) and C* (10.60) of the breast; and males of L* (55.09) of the thigh. Among males, poultry fed with the control diet and chromium showed higher SF values of the thigh than those supplemented with selenium; for the treatment with chromium, the males presented superior average of SF of the thigh and, in contrast, for the treatment with selenium, the females had the highest average. Samples submitted to the period of 12-month of storage showed higher values of substances reactive to thiobarbituric acid (TBARS) in both cuts. Supplementation with biocomplexed chromium and selenium did not cause changes in meat quality; females presented better attributes of meat quality.(AU)

Difficulty in detecting low levels of polymyxin resistance in clinical Klebsiella pneumoniae isolates: evaluation of Rapid Polymyxin NP test, Colispot Test and SuperPolymyxin medium.

Polymyxins are important therapeutic options for treating infections, mainly those caused by carbapenem-resistant Klebsiella pneumoniae. Specific chemical characteristics of polymyxins make it difficult to perform antimicrobial susceptibility testing, especially within the clinical laboratory. Here we aimed to evaluate the performance of three phenotypic methods: Rapid NP Polymyxin Test, ColiSpot test and the SuperPolymyxin medium. To accomplish this, 170 non-duplicate clinical K. pneumoniae isolates were analysed (123 colistin-resistant and 47 susceptible). The sensitivity and specificity obtained for Rapid Polymyxin NP Test, Colispot and SuperPolymyxin medium were, respectively, 90% and 94%, 74% and 100%, and 82% and 85%. Very major errors occurred more frequently in low-level colistin-resistant isolates (MICs 4 and 8 µg/mL). Rapid Polymyxin NP proved to be a method capable of identifying colistin-resistant strains in acceptable categorical agreement. However, major errors and very major errors of this method were considered unacceptable for colistin-resistance screening. Although the Colispot test is promising and easy to perform and interpret, the results did not reproduce well in the isolates tested. The colistin-containing selective medium (SuperPolymyxin) showed limitations, including quantification of mucoid colonies and poor stability. Nevertheless, Colispot and SuperPolymyxin medium methods did not present acceptable sensitivity, specificity and categorical agreement. It is essential to use analytical tools that faithfully reproduce bacterial resistance in vitro, especially in last-line drugs, such as polymyxins, when misinterpretation of a test can result in therapeutic ineffectiveness.

New-onset lupus nephritis after male-to-female sex reassignment surgery.

We report an original case of a 27-year-old transgender woman who developed lupus nephritis after male-to-female sex reassignment surgery. The patient had been taking hormones to induce feminization since the age of 18. She was admitted with malar "butterfly" rash, anasarca and hypertension, associated with an increase in serum creatinine (1.7 mg/dl). Renal involvement was characterized by nephritic and nephrotic syndrome. Autoantibody tests were positive for antinuclear antibodies and anti-double-stranded DNA, and complement levels were markedly reduced. Renal biopsy demonstrated diffuse proliferative glomerulonephritis and granular immune complexes deposits with a "full-house" pattern at the immunofluorescence level. The induction treatment was realized with corticosteroid and cyclophosphamide and maintenance immunosuppression phase with mycophenolate, obtaining complete remission. We speculated that lupus nephritis was induced by estrogens and antiandrogen therapy and gonadectomy. In the present case, we discuss the role of sex hormones in systemic lupus erythematosus onset and review the cases linked to transgender patients.

Fatal pneumonitis induced by oxaliplatin: description of three cases.

We describe 3 fatal cases of interstitial pneumonitis rapidly evolving to pulmonary fibrosis and death after the administration of oxaliplatin as part of the FOLFOX regimen. Due to the widespread use of oxaliplatin in oncology, clinicians should be aware of the risk and severity of oxalipatin-induced interstitial pneumonia.

Association of MBL2 gene exon 1 variants with autoimmune thyroid disease in Brazilian patients.

We investigated the association between MBL2 gene exon 1 functional polymorphisms and autoimmune thyroid disease (AITD) in 163 Brazilian patients (87 with Hashimoto thyroiditis, HT; 76 with Graves' disease) and 214 healthy controls. Individuals carrying MBL2 O allele are at higher risk of developing AITD (OR = 1.58, 95% CI: 1.11-2.26; P-value = 0.009) and HT (OR = 1.67, 95% CI: 1.09-2.55; P-value = 0.013) as suggesting a possible role for mannose-binding lectin in influencing disease susceptibility.

Crescimento e desenvolvimento de boto-cinza (Sotalia guianensis) do litoral do Espírito Santo / Growth and development of estuarine dolphin (Sotalia guianensis) from Espírito Santo coast

Estudou-se o desenvolvimento do boto-cinza (Sotalia guianensis) do litoral do Espírito Santo e verificou-se se a análise das radiografias da aleta peitoral pode ser utilizada para tal. Trinta e sete botos passaram pela determinação do comprimento total (CT), análise do grau de fusionamento das vértebras e radiografia das aletas peitorais. O CT ao nascimento foi de 103,3cm e o de animais maduros fisicamente 187,5cm. Observou-se correlação entre o CT, as epífises distais do rádio e da ulna e correlação entre o grau de fusionamento vertebral e a epífise distal do rádio. Concluiu-se que a análise radiográfica das aletas peitorais é uma boa maneira de avaliar o grau de maturação física do boto.

The aim of this study is to analyze the development of the estuarine dolphin from the coast of Espírito Santo and verify that the analysis of X-rays of pectoral fin can be used for such. Thirty-seven Sotalia guianensis were used, determining the TL, examination of the degree of fusion of the vertebrae and X-ray of pectoral fins. At birth the TL is 103.3cm and in physically mature animals the TL is 187.5cm. The TL showed a significant correlation with the epiphyses of the distal radius and ulna and the degree of spinal fusion showed significant correlation with distal radius. It can be concluded that the X-ray analysis of the pectoral fins is a good way of assessing the physical maturation of these animals and can be used in routine procedures.

Sealing ability, water sorption, solubility and toothbrushing abrasion resistance of temporary filling materials.

AIM: To evaluate marginal seal, water sorption, solubility and loss of mass after brushing of several temporary filling materials. METHODOLOGY: For marginal seal, Class I cavities, including endodontic access preparations, were made in human molar teeth and restored using one or other of several temporary filling materials (n = 10): zinc oxide/calcium sulphate-based cement (Cavit, 3M,ESPE, St. Paul, MN, USA), zinc oxide/eugenol cement (IRM, Dentsply Caulk, Milford, DE, USA), glass ionomer cement (Vidrion R, SSWhite, Rio de Janeiro, RJ, Brazil) or a dimethacrylate-based filling (Bioplic, Biodinâmica, Londrina, PR, Brazil). Dye penetration was assessed after thermocycling and immersion in 0.5% basic fuchsine solution. For water sorption, solubility and loss of mass analyses, disc-shaped specimens were made. Water sorption and solubility were evaluated by mass alteration after storage in distilled water for 7 days (n = 7). Loss of mass was calculated based on the difference of mass after abrasion with a toothbrush (n = 5), and surfaces were analysed by SEM. Data of water sorption, solubility and loss of mass were submitted to anova and Tukey's test, and marginal sealing data to Kruskal-Wallis test (P < 0.05). RESULTS: Statistically significant differences were observed for marginal sealing (P < 0.0001), water sorption (P < 0.01), solubility (P < 0.01) and loss of mass (P < 0.05). Bioplic had the best marginal seal. Cavit had the greatest water sorption and solubility. Vidrion R and Bioplic had the lowest solubility. Loss of mass after brushing was higher for Cavit, followed by Bioplic, IRM and Vidrion R. Cavit and Vidrion R were worn aggressively by brushing. CONCLUSIONS: The resin-based temporary filling Bioplic produced the best marginal seal, and was associated with the lowest water sorption, solubility and loss of mass.

Intraoperative bleeding during vitrectomy for diabetic tractional retinal detachment with versus without preoperative intravitreal bevacizumab (IBeTra study).

AIMS: To compare the amount of intraoperative intraocular bleeding in patients with diabetes with macula-involving tractional retinal detachment (TRD) undergoing pars plana vitrectomy (PPV) with and without preoperative intravitreal bevacizumab (IVB) injection. METHODS: An institutional study was carried out with consecutive patients with diabetic retinopathy and macula-involving TRD of recent (3 months) onset who were randomly assigned to PPV only (PPV group) or PPV combined with one IVB (1.5 mg/0.06 ml) injection 2 weeks prior to surgery (bevacizumab (BEV)/PPV group). All patients underwent 23-gauge PPV 3 weeks after baseline. The main outcome measure was erythrocyte count in the fluid retrieved from the vitrectomy cassette using a Neubauer counting chamber. RESULTS: The study included 20 patients. The mean erythrocyte count was 14,865x10(3) (SD 19,332x10(3); median 4,500x10(3)) cells in the BEV/PPV group, and 176,240x10(3) (SD 108,375x10(3); median 166,600x10(3)) cells in the PPV group. The mean erythrocyte count was significantly lower in the BEV/PPV group than in the PPV group (p<0.0001). No major adverse events were identified. CONCLUSION: Preoperative IVB injection was associated with reduced intraocular bleeding during 23-gauge PPV for diabetic macula-involving TRD. Further studies are needed to confirm our preliminary findings. TRIAL REGISTRATION NUMBER: NCT00690768.

Psoriasis vulgaris and human leukocyte antigens.

BACKGROUND: Psoriasis vulgaris is a skin disease with a complex immunological and genetic background, triggered by environmental factors. The association of human leukocyte antigens (HLA) and psoriasis has long been reported on population and familial studies. OBJECTIVES: To review and discuss studies on psoriasis vulgaris and HLA, in Caucasian and non-Caucasian populations. METHODS: The major population studies on psoriasis vulgaris and the associated HLA antigens and alleles are described and discussed based on a review of the current literature. RESULTS: Population studies demonstrate the presence of different HLA specificities as well as extended haplotypes in patients with psoriasis, when compared to controls. Some alleles occur in a lower frequency in patients with psoriasis, indicating they could be protection alleles. In all studies which HLA class I was typed, Cw6 or Cw*0602 was present in a significant frequency in patients with psoriasis, mainly when early onset and positive family history were considered. HLA-DRB1*0701 was also present in a higher frequency in patients in different populations. CONCLUSIONS: Different antigens and alleles from both HLA classes I and II were seen in a significantly higher frequency in patients with psoriasis vulgaris. HLA Cw*0602 and DRB1*0701 were represented in different reports, and the former was related mainly to psoriasis type I.

Correlation between HLA and pityriasis rosea susceptibility in Brazilian blacks.

OBJECTIVES: The human leucocyte antigen (HLA) has been related to susceptibility factors in several diseases. This study aimed to determine the potential genetic susceptibility of patients with pityriasis rosea (PR) through HLA molecular typing analysis. METHODS: The method of choice was polymerase chain reaction with sequence-specific primers (PCR-SSP) using low-resolution typing kits, with determination of the alleles class I (HLA-A, HLA-B and HLA-C) and class II (HLA-DRB1, DRB3, DRB4, DRB5 and DQB1) performed in 30 Afro-Brazilian PR-diagnosed patients and 45 healthy individuals as the control group (PR-C). RESULTS: Analysis of the HLA typing results showed that the relative risk (RR) of 4.00 [95% confidence interval (95% CI) 1.20-13.28, two-tailed P = 0.018] for allele HLA-DQB1*04 class II, detected in 33.3% of PR patients, was significant. By contrast, in the control group only 11.1% of subjects had that allele. Three out of six B*51 alleles and three out of six B*53 alleles detected in PR patients were found, together with the allele DQB1*04. CONCLUSION: We suggest that alleles DQB1*04 may be involved in the genetic susceptibility of PR based on the significant predominance of those alleles observed in the black PR patients. We also recommend that more studies are conducted on populations of other ethnic origins, preferentially with higher resolution techniques of DNA typing.

Leukocytosis and blood eosinophilia in a polyparasitised population in north-eastern Brazil.

It has long been known that leukocytosis and blood eosinophilia are common in the tropical environment, but data derived from population-based studies are scarce. A study was undertaken in a fishing village in north-east Brazil where both intestinal helminthiases and parasitic skin diseases are common. Of 409 individuals studied, 128 (31.3%) were infected with one intestinal helminth or ectoparasite species, 93 (22.7%) with two, 61 (14.9%) with three, 25 (6.1%) with four and 11 (2.7%) with more than four species; no parasites were found in 91 (22.2%) individuals. Leukocyte counts ranged between 3,300 cells/microl and 16,100 cells/microl (median, 7,200 cells/microl) and eosinophil counts between 40 cells/microl and 5,460 cells/microl (median, 455 cells/microl). Eosinophilia (>500/microl) was detected in 44.7% of the individuals, and hypereosinophilia (>1,000/microl) in 12.9%. Thirty-six (8.8%) individuals showed leukocytosis. While 75% of individuals with normal eosinophil counts were considered parasite-free, only 14% with eosinophilia and 11% with hypereosinophilia did not have enteroparasites or ectoparasites. Multivariate regression showed that the probability of eosinophilia and hypereosinophilia, but not of leukocytosis, increased with the number of parasite species present. The data show that eosinophilia occurs in almost one-half of the individuals from a resource-poor setting and that it is significantly associated with the presence of intestinal helminths, but not with the presence of ectoparasites.

Lipid profile and body composition of HIV-1 infected patients treated with highly active antiretroviral therapy

Highly active antiretroviral therapy (HAART) has been associated with the development of a clinical group and metabolic disorders such as peripheral lipodystrophy syndrome in AIDS. The aim of this study was to analyse the lipid profile, the clinical aspects, and the body composition of HIV-1 infected individuals treated with or without protease inhibitor (PI) during the highly active antiretroviral therapy. In total, 62 individuals were evaluated in this study; 15 healthy individuals (Control Group; CG), 11 HIV-1 infected individuals treated without antiretroviral therapy (Group 1: G1), 14 HIV-1 infected individuals treated with antiretroviral therapy plus protease inhibitor (Group 2: G2), and 11 HIV-1 infected individuals treated with antiretroviral therapy without protease inhibitor (Group 3: G3), mean age 35 years old. The time interval for G2 and G3 was greater than or equal to nine months. Patients receiving HAART with PI had significantly lower viral loads, hypertriglyceridemia, and low HDL levels (p<0.05). There were no differences between groups in relation to the lean body mass percentage obtained by mid-arm muscle circumference adequacy or by bioelectrical impedance. The lower percentage of body fat observed in all the HIV-1 infected patients by antropometric assessment and the decreased tricipital skinfold adequacy in the group treated with PI in relation to CG may suggest lipodystrophy in the upper limbs, especially on those treated with PI

Phase I-II study on isolation antiblastic fotemustine perfusion after dacarbazine chemosensitization for advanced melanoma of the extremities.

Isolation limb perfusion (ILP) is the treatment of choice for locally advanced limb melanoma. With melphalan, the referral drug, complete response (CR) is achieved in about 50% of patients, but significant local toxicity occurs in up to 30%. The aim of the present phase I-II study was to challenge fotemustine (F) in ILP after systemic chemosensitization with dacarbazine (DTIC), given its lower toxicity and greater efficacy, as reported in a previous pilot study. Eleven patients with locally advanced limb melanoma were subdivided into triplets, and given F ILP at escalating doses (starting from 25 mg/l) after intravenous administration of 500 mg/m2 DTIC. Acute and chronic locoregional and systemic toxicity, tumour response and clinical outcome were evaluated. Two patients in the first triplet had G3-G4 local toxicity, so that the scheduled F dosage was halved. At drug levels of 12.5, 15.6 and 18.2 mg/l, local toxicity decreased, but only one of eight patients showed CR. The trial was then interrupted due to the low tolerability and poor efficacy of this perfusion regimen. At present, F ILP after DTIC chemosensitization should not be recommended for the treatment of locally advanced limb melanoma.

Risk factors associated with an outbreak of dengue fever in a favela in Fortaleza, north-east Brazil.

To increase the effectiveness of ongoing anti-dengue control measures, we conducted a case-control study in a favela in Fortaleza (north-east Brazil) during an outbreak of dengue fever. Cases were defined according to the national guidelines for dengue control as well as based on the detection of IgM-dengue antibodies, and 34 cases and 34 controls were investigated. Significant risk factors were: living in a street perpendicular to the beach on which the favela is situated (P < 0.0001), an interval > 30 days since the last visit of the vector control agent (P=0.001), receptacles in the garden or courtyard (P=0.001), plants with temporary water pools on the property, gutter to collect rainwater, uncovered water storage container (all P=0.02), and no waste collection (P=0.03). Socio-economic variables were not associated with dengue fever. The probable starting point of the epidemic was an uncovered water tank on the roof of the house adjacent to the index case. From there, the outbreak spread uphill parallel to the prevailing direction of the wind. Thus, the chronological and spatial evolution of the epidemic could have been forecast after the first cases had occurred. This example of investigative epidemiology in an operational setting shows that targeted intervention leading to increased effectiveness of control measures is possible.

Detection and localization of non-HLA-ABC antigenic sites relevant to kidney rejection on endothelial cells.

Immunological rejection of kidney allografts is usually attributed to presensitization to HLA antigens. However, data on HLA identical transplant rejections indicate that non-HLA antigens may also be involved, and it has been suggested that vascular endothelium represents the main target cell. The purpose of the present study is to describe a method of detecting non-HLA antibodies immunocytochemically. We showed the molecular independence between HLA-ABC molecules identified by the monoclonal antibody w6/32, and antigenic sites identified by a kidney rejection patient serum, previously characterized, on cultured endothelial cells isolated from human umbilical cords by collagenase digestion. Single immunofluorescence staining indicated the molecular independence between these antigenic sites, as the first serum showed a granular pattern, diffused throughout the cytoplasm and the other a reticular pattern restricted to the same cytoplasmic region. This result was confirmed by double labeling. Immunoelectronmicroscopy study also confirmed site independence, showing labeling patterns with different intensities and distinct localizations, using 10- and 20-nm colloidal gold particles to reveal HLA-ABC and non-HLA-ABC determinants, respectively. In conclusion, cultured endothelial cells may be used immunocytochemically to detect non-HLA-ABC determinants of antibody reactivity in renal graft recipients, and the indirect immunofluorescence may be the methodology of choice, since it is easy, reliable and low cost.

Pressure-induced formation of inactive triple-shelled rotavirus particles is associated with changes in the spike protein Vp4.

Rotaviruses are non-enveloped, triple-shelled particles that cause enteritis in animals and humans. The interactions among the different viral proteins located in the three concentric layers make the rotavirus particle an excellent model for physico-chemical and biological studies of viral assemblage. SA11-4S rotaviruses subjected to high pressure were inactivated by more than five log units. After pressure treatment, the particles were recovered with slight structural changes when compared to the control. Electron microscopy suggested subtle changes in the viral outer layer in some pressurised particles. Fluorescence spectroscopy showed that much more dramatic changes were produced by urea denaturation than by pressure. Based on the fluorescence spectrum, the genome resistance to ribonuclease, and the absence of changes in hydrodynamic properties, there was little or no disruption of the capsid under pressure. On the other hand, hemagglutination assays indicated that the main component affected by pressure was the spike protein VP4, thus accounting for changes in interaction with host cells and greatly reduced infectivity. The changes leading to inactivation did not cause removal of VP4 from the outer capsid, as verified by size-exclusion chromatography. Antibodies raised against pressurised material were as effective as antibodies raised against the intact virus, based on their neutralisation titre in plaque reduction assays, enzyme-linked immunosorbent assays and direct interaction with the particle, as measured by gel-filtration chromatography. Therefore, the new conformation of the pressurised particle did not result in loss of immunogenicity. We propose that pressure alters the receptor-binding protein VP4 by triggering changes similar to those produced when the virus interacts with target cells. As the changes in VP4 conformation caused by pressure occur prior to virus exposure to target cells, it leads to non-infectious particles and may lead to the exposure of previously occult epitopes, important for vaccine development.

[Surveillance of infant deaths in local health systems: assessment of verbal autopsy reports and of information gathered from health agents]. / Vigilância de óbitos infantis em sistemas locais de saúde: avaliação da autópsia verbal e das informações de agentes de saúde.

Knowing the vital statistics of a population is fundamental in controlling morbidity and mortality and improving living conditions. In Brazil, however, the available health information systems do not provide reliable vital statistics. This study was carried out in Quixadá, Icapuí, and Jucás, three municipalities in the state of Ceará that had good coverage by primary health care services. The study used an epidemiological instrument known as a "verbal autopsy" and investigated 215 (90%) of the 237 deaths of children younger than 1 year identified in 1993 and 1994 in the three communities. We investigated socioeconomic characteristics; sanitary conditions; nutritional status; the course of illness, health care, and death; the cause of death; and the operation of the national mortality information system and of the community health agents system. According to the verbal autopsies, diarrhea was the cause of death in 39% of the cases, followed by premature birth (17%), and acute respiratory infections (10%). Even though 79% of the families had sought formal health care services during the child's illness, 49% of the infants had died at home. This suggests limited effectiveness in the identification and treatment of sick infants. In 84% of the cases the family sought help from folk healers. Although community health agents reported 78% of the deaths, only 29% of the families had sought help from the agents during the children's illnesses. In terms of the statistical agreement between the information on the cause of death provided by community health agents and by the verbal autopsies, the agreement was good for diarrhea, intermediate for other causes, and low for acute respiratory infections. Making verbal autopsy a routine part of primary health care services in Ceará would provide invaluable information for local health care teams and would raise a critical consciousness fostering a reduction in infant mortality.

Allelic distribution of four tetranucleotide repeat loci (D3S1358, D18S51, D19S253, and FGA) in a population from Porto (North Portugal).

Allele frequencies for four short tandem repeat loci were determined in a population sample from Porto (North Portugal), using the polymerase chain reaction (PCR), in order to investigate possible genetic differences between populations from the center and north of Portugal. After denaturing PAGE electrophoresis, nine alleles were identified for D3S1358 (n = 256), 13 alleles for D18S51 (n = 235), 10 alleles for D19S253 (n = 238), and 15 alleles for FGA (n = 181). No deviations from Hardy-Weinberg equilibrium were found. The allele frequencies observed are similar to those of the Portuguese population compared except for the D3S1358 system.
