Reproductive ecology of the seabob shrimp Xiphopenaeus kroyeri(Heller,1862)in a coastal area of Southern Brazil

The predictability of certain environmental factors that affect the life cycle of the seabob shrimp Xiphopenaeus kroyeri(Heller,1862) was evaluated in a study of its reproductive biology in an area adjacent to Babitonga Bay,State of Santa Catarina,Brazil. Monthly sampling was conducted from July 2010 through June 2011 at depths of 5,8,11,14,and 17 m.76 004 individuals were obtained,with a pronounced peak in absolute abundance in austral autumn(34 208),coinciding with the annual closed season from March to May. Grain size composition of the sediment showed the closest relationship to the distribution of individuals(multiple linear regression,P o their burying habit. The observed correlations between the abundance of reproductive males(bearing spermatophores) and females with spent gonads(cross-correlation,P oductive males and reproductive females(with a 1-month lag) suggest that the peak of reproductive males preceded the peak offemale ones. This result agrees with the pattern expected for females,which copulate in post-ecdysis(spent gonads). Spawning seemed to take place at greater depths,as evidenced by the concentration of reproductive females in these areas. The reproductive activities observed here confirm that this species follows a tropical/subtropical reproductive pattern,spawning continuously throughout the year,with the highest peaks in spring and autumn. The data indicate that the juvenile recruitment period observed in August-September resulted from the reproductive output noted in April–May. Additionally,the reproductive period recorded in November led to the juvenile peak observed in March–May.

Gait, posture and transfer assessment among elderly practitioners and non-practitioners of Tai Chi Chuan

Falls may be devastating events among elderly people. Tai Chi Chuan is a type of moderate sports exercise that demonstrates improvements in balance, gait and posture. The aim here was to assess the influence of this method on the balance, gait and posture of healthy active elderly people. A controlled cross-sectional study was conducted on 76 volunteers, divided into two groups: 51 volunteers Tai Chi Chuan group mean age 76.8 years and 25 volunteers control group mean age 70.3 years. Both groups underwent the Modified Clinical Test on Sensory Interaction for Balance (mCTSIB), Walking Test (WT), Sit-to-Stand Transfer Test (SSTT) and Unipedal Assessment Test (UT), using the Neurocom Balance Master system. Result: In conditions Static balance tests: the mCTSIB-Tai-Chi Group had a lower sway velocity (°/s) on a firm surface with eyes open and medio-lateral direction, Foam Surface with eyes open medio-lateral and anteroposterior direction. Unilateral Stance Tai-Chi Group had a lower mean sway velocity (°/s) with open eyes (right and left), but with eyes closed. The Control Group showed a lower sway velocity. Under Dynamic Balance: Walk Across Test Tai-Chi Group presented a walking speed greater than the Control Group. In Sit to Stand Transfer Test, Tai-Chi Group showed a better index rising to lift up and lower oscillation in the final standing position. Conclusion: The Tai Chi Group was shown to be a protection factor for preserving and maintaining the static and dynamic positions of posture and gait.

Introduction: Pentalogy of Cantrell is a rare disorder described by Cantrell in 1958 and characterized by heart anomalies, involving defects of the diaphragm, abdominal wall, supraumbilical region and pericardium. Methods: We report a case of the disease that presented with agenesis of the sternum and partial absence of costal cartilage, treated by a multi-disciplinary team. Results: The patient underwent median sternotomy. An enlarged heart, compromising the pulmonary trunk and the right ventricle, and a left superior vena cava were identified. The right atrium was opened and an interventricular communication of around 10 mm in diameter was seen through the tricuspid valve. Following the repair of the heart defects, chondroplasty and placement of biological mesh (Bioway of Gore) were performed. Conclusion: A Successful surgical treatment for Cantrell Syndrome includes correction of the cardiac malformation, a good repair of thoracoabdominal wall.
