Plasticidade Fenotípico-vegetativa De Oeceoclades Maculata (lindl.) Lindl. (orchidaceae) Em Dois Ambientes De área Florestada

Phenotypic plasticity is the genotypic capacity in producing different phenotypes as a response to different environmental conditions. The invading orchid Oeceoclades maculata has high adaptative capacity related to the colonization of different habitats, particularly, anthropic ones. Current paper provides morphobiometric analyses of the species to report plastic-phenotypic-vegetative adaptations in two luminic environments in the Arboreto de Essências Nativas, in Araras SP Brazil. Fifty specimens of Oeceoclades maculata, featuring physiological maturity, were collected from the edge and the interior of the forest fragment. The following biometric data were taken: mean number of roots and pseudobulbs, leaves, mean length of roots and pseudobulbs, leaves, mean diameter of leaves and pseudobulbs, mean length and thickness of leaves, fresh mass of roots and pseudobulbs and leaves, dry mass of roots and pseudobulbs and leaves. Phenotypic plasticity index was calculated for all morphobiometric variables. Morphobiometric variables revealed plastic-phenotypic-vegetative adaptations in Oeceoclades maculata specimens in different environments of the Arboreto de Essências Nativas. Adaptations are mainly co-related to luminic conditions on the fragmentś edge and interior.9363564

Hydatidiform mole resulting from sexual violence

<p>Abstract</p> <p>Background</p> <p>Hydatidiform mole (HM) is characterized by abnormal proliferation of human trophoblast with producers functioning tissues of human chorionic gonadotropin. It can evolve with ovarian cysts tecaluteínicos, hypertension of pregnancy or hyperthyroidism. The incidence of HM is variable and its etiology poorly known, associated with nutritional factors, environmental, age, parity, history of HM, oral contraceptives, smoking, consanguinity or defects in germ cells. There is no reference in literature on HM resulting from sexual violence, objective of this report.</p> <p>Method</p> <p>Description of two cases of HM among 1146 patients with pregnancy resulting from sexual violence treated at Hospital Pérola Byington, São Paulo, from July 1994 to August 2011.</p> <p>Results</p> <p>The cases affected young, white, unmarried, low educated and low parity women. Sexual violence was perpetrated by known offenders unrelated to the victims, under death threat. Ultrasound and CT of the pelvis showed bulky uterus compatible with HM without myometrial invasion. One case was associated with theca lutein cysts. The two cases were diagnosed in the second trimester of pregnancy and evolved with hyperthyroidism. There was no hypertension, disease recurrence, metastasis or sexually transmitted infection.</p> <p>Conclusion</p> <p>The incidence of HM was 1:573 pregnancies resulting from rape, within the range estimated for Latin American countries. Trophoblastic material can be preserved to identify the violence perpetrator, considering only the paternal HM chromosomes. History of sexual violence should be investigated in cases of HM in the first half of adolescence and women in a vulnerable condition.</p
