Acupuncture-ameliorated menopausal symptoms: single-blind, placebo-controlled, randomized trial

Objectives To evaluate the effects of acupuncture and sham-acupuncture on women with menopausal symptoms as reflected in the intensity of their hot flushes and the Kupperman Menopausal Index (KMI). Method This was a randomized, single-blind, placebo-controlled, cross-over trial with 81 patients assigned to two groups: Group 1 received 12 months of acupuncture, then 6 months of sham-acupuncture treatment (n = 56) and Group 2 received 6 months of sham-acupuncture, then 12 months of acupuncture treatment (n = 25). The needles were inserted in a harmonic craniocaudal manner at a depth of about 2 cm, and each session lasted approximately 40 min. The efficacy of acupuncture in ameliorating the climacteric symptoms of patients in postmenopause was determined through the KMI and the intensity of hot flushes. The analysis of variance method for two factors and repeated measures was applied. Results The baseline values of the women in both groups were similar for the KMI score and number of hot flushes. At the end of 6 months, the values for the KMI and hot flushes for the women in Group 1 were lower than those of the women in Group 2 (p < 0.05). After 12 months, the KMI and hot flush data were similar in both groups. After 18 months, the values of the KMI and hot flushes for the women in Group 2 for were lower than those of the women in Group 1 (p < 0.05). Conclusion Acupuncture treatment for relieving menopausal symptoms may be effective for decreasing hot flushes and the KMI score in postmenopausal women.

Three-vortex configurations in trapped Bose-Einstein condensates

We report on the creation of three-vortex clusters in a (87)Rb Bose-Einstein condensate by oscillatory excitation of the condensate. This procedure can create vortices of both circulations, so that we are able to create several types of vortex clusters using the same mechanism. The three-vortex configurations are dominated by two types, namely, an equilateral-triangle arrangement and a linear arrangement. We interpret these most stable configurations respectively as three vortices with the same circulation and as a vortex-antivortex-vortex cluster. The linear configurations are very likely experimental signatures of predicted stationary vortex clusters.

Estrutura populacional do camarão-branco Litopenaeus schmitti nas regiões estuarina e marinha da baixada santista, São Paulo, Brasil

The white-shrimp Litopenaeus schmitti distributes in West Atlantic Ocean, occurring along all Brazilian cost. Population structure in the Baixada Santista region was identified from samples obtained from artisanal and industrial fishery between June of 2005 and May of 2006. A total of 2.912 specimens were collected, being 2.138 females (1.008 in the estuary and 1.130 in the marine region) and 774 males ( 334 in the estuary and 440 in the marine region). Environmental parameters were annotated together the sampling, allowing to identify that water temperature influences directly the catches. Catches variations, length composition of samples by sex and gonadal maturation of females allowed to identify that: (i) estuary is used as a nursery area by individuals with small lengths, most young; (ii) marine region is used by larger individuals ( adults) and the spawning period extend from June to February, mainly between November and January. It was verified that estuarine fishery ( artisanal) focuses immature and in development individuals, with small lengths and, the marine fishery ( industrial) focuses adults during the whole year and, only in the summer, youngling from spawn. The length of first gonadal maturation of females was estimated in 15,8mm. These results and diagnoses must be considered in the management of L. schmitti fishery in Baixada Santista region.

Letters that construct limits: intellectual and political projects in the letters of Capistrano de Abreu to Barao do Rio Branco (1886-1903)

The intention of this paper is to analyze the letters from Capistrano de Abreu to Barao do Rio Branco in the years between 1886 and 1903. The focus will be given to the divergences around the notion of territorial formation, a basic concept for these authors who were thinking about the construction of a historical narrative at the end of the 19(th) and beginning of the 20(th) century. Later, the question is the construction of the craft of the historian in the letters of Capistrano de Abreu and his distinction and proximity to the ideas of the Barao do Rio Branco.

Fractured Orbital Wall Reconstruction With an Auricular Cartilage Graft or Absorbable Polyacid Copolymer

Objective: The objective of the study was to compare the functional and aesthetic results of fractured orbital wall reconstruction with an auricular cartilage graft or absorbable polyacid copolymer. Materials and Methods: Twenty patients with blow-out orbital fracture/orbital floor associated or not with the medial wall were assessed by the same craniofacial surgical group. All were evaluated preoperatively and postoperatively by an ophthalmologist for diplopia, enophthalmos, exophthalmos, sensitivity, ophthalmic reflexes, intraocular pressure, and visual field. The patients were subjected to a preoperative facial multislice computed tomographic scan, repeated 6 months after surgery. Eight patients underwent reconstruction with an auricular cartilage graft, and 12 patients, with blade absorbable polyacid copolymer. Subtarsal access was used for all patients. Results: Two patients showed temporary ectropion, 1 in each group. All patients presented satisfactory ocular function, and all tests revealed good orbital delineation, orbital symmetry, periorbital sinus individualization, and reduction of blow-out. Conclusions: The blow-out orbital wall reconstruction can be performed with the use of an auricular cartilage or with a blade absorbable copolymer without differences regarding functional or aesthetic complications and sequelae.
