Distichophyllum meizhii Tan & Lin and D. wanianum Tan & Lin (Hookeriaceae) collected from southwestern region of China are described as new to science. Also, Horikawaea redfearnii Tan & Lin is described as a new species based on collections from Hainan Island of China and Palawan Island of the Philippines.

Tratado del tránsito

Una reflexión sobre el significado de «tránsito» sirve para anudar la experiencia de la ciudad y de la traducción. El tránsito es un espacio de desposesión de identidades, una incógnita irreductible a toda tentativa de elucubración de saber. Como objeto de estudio, se encuentra tanto en pensadores modernos como J. Lacan o M. Delgado como en otros muy antiguos como Lin-Tsi.A reflection on the meaning of the word "transit" serves the purpose to link the experience of the city with the experience of translation. "Transit" designates a space of dispossession of identities, an enigma that knowledge cannot resolve. However, it has been the subject of study of contemporary thinkers such as J. Lacan and M. Delgado as well as ancient philosophers such as Lin-Tsi

Evaluation Of Rat Testes Treated With Arctium Lappa L: Morphometric Study

Arctium lappa L. (burdock) is a plant brought from Japan and acclimated in Brazil, which is widely used in popular medicine all over the world. This study was carried out to assess the possible effects of A. lappa in testes of adult Wistar rats. They received the extract in water bottles at doses of 10 or 20 g/L daily for 40 days. There were no significant alterations in the biometric data including body and accessory sexual organs weight and in the histometric data such as volume density of the testis compartments and Leydig cell morphometry. Unaltered histometric and biometric data shows that A. lappa did not cause impairment of spermatogenesis.242112117Capasso, R., Izzo, A.A., Pinto, L., Bifulco, T., Vitobello, C., Mascolo, N., Phytotherapy and quality of herbal medicines (2000) Fitoterapia, 71, pp. 58-65Chen, F., Wu, A., Chen, C., The influence of different treatments on the free radical scavenging activity of burdock and variations of its active components (2004) Food Chem, 86, pp. 479-484Creasy, D.M., Pathogenesis of Male Reproductive Toxicity (2001) Toxicol.
