“Wisdom of crowds” refers to the phenomenon that average opinion a group individuals on given question can be very close true answer. It requires large diversity opinions, but collective error, difference between and value, has small. We consider stochastic dynamics where change their based opinions others (social influence α), some degree also stick initial (individual conviction β). then deri...

The objective of this article is to describe a case of an electric burn to the genitalia causing scrotal and testicular lesion, and the subsequent reconstruction using a skin graft. The patient was a 10-year-old boy who was victim of an electric burn that harmed the genitalia. There was extended skin loss, penile, scrotal and partial testicular lesion. The treatment consisted of plastic surgery...

OBJECTIVES The objective of this study was to identify and study adults who have a 46,XY karyotype and presented as infants or children with variable degrees of undermasculinization of their genitalia (female genitalia, ambiguous genitalia, or micropenis). Participants' knowledge of their condition, satisfaction with their knowledge, and desire for additional education about their intersex cond...

The male genitalia of arthropods consistently show negative static allometry (the genitalia of small males of a species are disproportionally large, and those of large males are disproportionally small). We discuss relations between the 'one-size-fits-all' hypothesis to explain this allometry and the regimes of selection that may be acting on genitalia. We focus on the contrasts between directi...

Seasogonia Young, 1986 is a sharpshooter genus with 13 species, four of them recorded from China. In this paper, Seasogonia sandaracata (Distant, 1908) is recorded as new for China and Seasogonia rufipenna Li & Wang, 1992 is regarded as a junior synonym of Seasogonia nigromaculata Kuoh, 1991. The morphological diversity of the female genitalia of Seasogonia is still poorly known. We provide her...

The interrelationship between the various bacteria isolated from the genital tract of rams and their host animals was studied. The pathogenicity of the different isolates varied. Several of these bacteria could be cultured in a medium consisting of a suspension of pen floor debris solidified with agar, while many organisms survived in the suspension for 10 days. Epidemiological investigations s...

Testicular descent as a prerequisite for the production of mature spermatozoa and normal external genitalia morphogenesis, and therefore facilitating copulation and internal fertilization, are essential developmental steps in reproduction of vertebrate species. Cryptorchidism, the failure of testis descent, and feminization of external genitalia in the male, usually in the form of hypospadias, ...
