BACKGROUND The variety of health problems (patient mix) that medical trainees encounter is presumed to be sufficient to master the required competencies. AIM To describe the patient mix of GP trainees, to study differences in patient mix between first-year and third-year GP trainees, and to investigate differences in exposure to sex-specific diseases between male and female trainees. DESIGN...

-The Texas Platycynorta transversalis is regarded as a junior synonym of V . sayi. Karyotypes of male and female V. sayi from central Texas reveal 2n = 78. This number is almost twice that previously reported for any other harvestman. The male reproductive system of V. sayi is described and illustrated. Natural history data are provided for egg laying and developmental times. The supercooling p...

Paper presents the first description of the so far unknown sexual generation of Pterocomma tremulae (Aphididae, Aphidinae): oviparous female and alate male. It also provides detailed description of the male reproductive system. Discussion focuses on comparative analysis of male reproductive system with other aphid groups and possible importance of its structure in resolving phylogenetic interre...
