Despite different modalities of action and significantly different effects on androgen levels, low doses of flutamide, finasteride, and EE-CPA constitute very satisfactory alternative therapeutic regimens in the treatment of hirsutism.
Linkage between sexual and asexual lineages: genome evolution in Bacillus stick insects
An overall picture of genomic diversification of parthenogens is therefore beginning to emerge, and the term meta-sexual is proposed to define those animals that reproduce by non-canonical sexual modes, but make use of egg and meiotic mechanisms.
Taxonomy and phylogeny of European Monochamus species: first molecular and karyological data
From a phyletic point of view, tree topology indicates the Japanese M. alternatus as the most differentiated taxon and the Euroasiatic M. saltuarius as basal to all other strictly European entities.
Cytology of Parthenogenesis in Bacillus whitei and Bacillus lynceorum (Insecta Phasmatodea)
These cytological findings fully support the genetic features ascertained for the two hybrids and provide evidence of their different and very likely independent meiotic adaptations to parthenogenetic reproduction.
Automictic parthenogenesis and its genetic consequence in Bacillus atticus atticus (Insecta Phasmatodea)
The meiotic divisions in the eggs of the diploid thelytokous stick insect Bacillus atticus atticus were examined in Feulgen squashes and an automictic type of parthenogenesis explains the clonal maintenance of cytotypes and also the transmission of different levels of heterozygosity.
Centrosome dynamics and inheritance in related sexual and parthenogenetic Bacillus (Insecta Phasmatodea)

It has been shown that in sexually reproducing species the spermatozoon does not contribute the centriole, so that the egg wholly provides the MTOC and the ensuing anastral spindle of the embryo.
Genome size in parental and hybrid species of Bacillus (Insecta, Phasmatodea) from southeastern Sicily: a flow cytometric analysis
These values represent the first flow cytofluorometric data on phasmatodean genome size and appear to be related to abundance and scarcity of C-heterochromatin, respectively.
Flow-cytometric analyses of intraspecific genome size variations in Bacillus atticus (Insecta, Phasmatodea)
A correlation between genome-size variations and geographic distribution is found and the adaptive nature of genome- size variations in response to environmental changes is discussed, and the class of DNA involved hypothesized.
Mate recognition and gamete cytology features allow hybrid species production and evolution in Bacillus stick insects
Morphological, karyological and genetic analyses clearly show that, owing to their persistence and incomplete reproductive isolation from ancestors, several all‐female complexes are much more diversified than generally assumed and that they may also have an evolutionary role.
The chromosome complement of the hybrid Bacillus whitei complex (Insecta phasmatodea). I : The paleo- and neo-standard karyotypes
C-positive satellites and corresponding Ag-NOR, are found on a wide array of chromosomes, mostly reflecting those of both parental species, but also on new locations, but rather useful in short-term comparisons.
