It is now almost a hundred years since Fournier, much against the standard belief of the times, proposed that syphilis was the likely cause of tabes dorsalis. Alfred Fournier (Fig. 1) was unquestionably the foremost syphilologist in France in the last 30 years of the 19th century, but his life and works are little known in English-speaking countries, probably because so few of his works have be...

The progressive elaboration of the sense of vision, which is reflected not only in the perfection of the structural mechanisms of the eye itself, but also in the divergent modifications of the pre-existing neural components and circuits of the visual system in the brain. This concept gave the much needed impetus to study the morphology of the pars ventralis nucleus of lateral geniculate complex...

Reproduction is an important life process in insects; however, few studies have attempted to demonstrate the association between reproductive activity and energy metabolism. To address this problem, we focused on the reproductive changes in Bactrocera dorsalis males. We analyzed B. dorsalis male gene expression profiles during mating (DM), 3 h after mating (A3HM) and 12 h after mating (A12HM). ...

An FAO/IAEA-sponsored coordinated research project on integrative taxonomy, involving close to 50 researchers from at least 20 countries, culminated in a significant breakthrough in the recognition that four major pest species, Bactrocera dorsalis, Bactrocera philippinensis, Bactrocera papayae and Bactrocera invadens, belong to the same biological species, Bactrocera dorsalis. The successful co...

OBJECTIVE The dorsalis pedis flap has reliable vascularity; however, its use is limited by reports of donor site morbidity including infection, delayed healing, exposure of tendons, and later contractures. The purpose of this study was to demonstrate its continued role in lower limb trauma when the donor site is reconstructed with MatriDerm to avoid complications. METHODS A 65-year-old man pr...

Determination of physiological state in insects is useful in furthering the understanding of how insect behavior changes with age. Central to this determination is the identification of characters that allow assessment of physiological age. While non-destructive measures produce the most desired outcomes, internal markers may be more diagnostic and reliable. In this study, key morphological cha...
