    OBJECTIVE: to evaluate the chronic effects of amprenavir on implantations, reabsorptions, fetuses, placentae, and maternal and fetal mortality in the albino rat. METHODS: five groups of EPM-1 Wistar pregnant rats were used: two controls: Contr1 (control of stress) and Contr2 (drug vehicle control), and 3 experimental groups that were treated once a day throughout gestation with 46mg/kg (Exper1), 138mg/kg (Exper2) and 414mg/kg (Exper3) of oral solution of amprenavir. The drug and the vehicle (propyleneglycol) were administered by gavage. The evaluations included maternal body weight gain, number of implantations, reabsorptions, fetuses, placentae and of intrauterine deaths as well as fetal and placental mean weight and major malformations. Fragments of lungs, kidneys, liver and intestines were collected and prepared for histopathological evaluation. RESULTS: Exper3 group tended to show lesser maternal body weight gain during gestation (P = 0.07), but amprenavir did not affect the intrauterine contents. The cytotoxic effect of the drug was observed with regard to the histopathological analyses of pregnant rat viscerae and to the maternal mortality rate: 50% in Exper1 and Exper2 groups, and 70% in Exper3 group. CONCLUSION: amprenavir exerted adverse side effects on maternal lung, gut, kidney and liver, and significantly increased maternal mortality rates in all administered doses and especially at 414 mg/kg.

    Estudo clínico e molecular em pacientes com artrogripose distal
    (Universidade Federal de São Paulo (UNIFESP), 2017-02-22) Nicola, Pablo Domingos Rodrigues De [UNIFESP]; Perez, Ana Beatriz Alvarez [UNIFESP]; Abath Neto, Osório Lopes; http://lattes.cnpq.br/4784102068388854; http://lattes.cnpq.br/8077340861513133; Universidade Federal de São Paulo (UNIFESP)
    Distal Arthrogryposis (DA) is a group of monogenic diseases of autosomal dominant inheritance, with incomplete penetrance, variable expressivity, characterized by congenital contractions of the distal joints of the limbs, not being caused by defects of the central and peripheral nervous system, by myopathies or by metabolic diseases. Ten different syndromes make up this group, the most common being DA1, DA2A and DA2B. Mutations in genes encoding skeletal muscle proteins (ECEL1, FBN2, MYBPC1, MYH3, MYH8, TNNI2, TNNT3, TPM2 and PIEZO2) are responsible for the etiology of AD. Objective: To describe clinical and molecular findings in patients with AD. To study the genes ACTA1, MYBPC1, MYH3, MYH8, TNNI2, TNNT1, TNNT3 and TPM2, in patients with AD and in their respective parents. To classify patients into syndromic groups and into molecular groups. Method: Evaluation of patients with congenital multiple arthrogryposis according to the clinical protocol. Extraction of genomic DNA from peripheral blood. State-of-the-art sequencing (NGS) using a panel of 8 genes (ACTA1, MYBPC1, MYH3, MYH8, TNNI2, TNNT1, TNNT3, TPM2). Validation of variants found in NGS by performing Sanger sequencing. Results: Among 106 patients with congenital multiple arthrogryposis, 19 subjects fulfilled the inclusion criteria for AD, 14 sporadic cases and 5 familial cases. Among the 19 individuals with AD, 7 individuals presented variants considered pathogenic, being 4 sporadic cases and 3 cases in the same family. Conclusions: Three variants of the MYH3 gene (c.1402T> C, c.2015G> A and c.5254G> T) were reported in individuals with DA1, DA2A and DA2B, two variants never described in the literature; one in the MYH8 gene (c.3349 + 1G> T) in an individual with DA7, not reported in the literature; and one in the TNNT3 gene (c.187C> T) in a sporadic case of DA2B and in 3 familial cases with DA2B that present phenotypic variability.
