This is the first study of isoenzyme variability in the leaf-cutting ants (Myrmicinae, Attini) Acromyrmex heyeri (Forel, 1899) and A. striatus (Roger, 1863) which are common throughout the southern Brazilian state of Rio Grande do Sul. We studied the alloenzyme variability of malate dehydrogenase (MDH), α-glycerophosphate dehydrogenase (α-GPDH) and amylase (AMY) in 97 colonies of A. heyeri and ...

Lichen striatus (LS) is a relatively rare and self-limited linear dermatosis of unknown etiology. It primarily affects children, with more than 50% of cases occurring in patients aged 5 to 15 years. The case of a 2-year-old boy who presented for evaluation of a nonpruritic linear rash on the left side of the lower abdomen of 3 weeks' duration is discussed. A diagnosis of lichen striatus (LS) wa...

Reef fish spawning aggregations have gained distinction in terms of their importance in species conservation and their socio-economic contribution to many Caribbean, tropical western Atlantic, and Gulf of Mexico fishing communities. With the near extinction of many spawning aggregations of large grouper and snapper throughout the Caribbean, Gulf, and tropical western Atlantic, it is essential t...

The banded butterflyfish (Chaetodon striatus) from the tropical and subtropical western Atlantic is a territorial, diurnal forager on benthic invertebrates. It is usually seen moving singly or in pairs, a few meters above the sea floor. We studied the foraging activity of C. striatus on rocky reefs in southeastern Brazil. This fish spent about 11 h and 30 min per day on feeding activities, and ...

INTRODUCTION A variety of cutaneous reactions have been described in patients receiving tumor necrosis factor alfa (TNF-a) inhibitors. Of particular interest in this scenario is the development of lichen planus and lichen planuselike eruptions. Because TNF-a is recognized as a significant factor in the induction of these dermatoses, their appearance after inhibition of TNF-a is perplexing. The ...

Lichen striatus is a self-limiting inflammatory dermatosis that is characteristically distributed along the Blaschko lines. It is usually seen in children although cases, with different histopathological features, have been reported in adults. In view of the characteristic clinical features of the disease in adults—with its papulovesicular aspect—it is known as blaschkitis. Subsequently, differ...

We sequenced the complete genome of the highly virulent Aeromonas schubertii strain WL1483, which was isolated from diseased snakehead fish (Channa argus) in China. The full genome sequence of A. schubertii WL1483 is 4,400,034 bp, which encodes 4,376 proteins and contains 195 predicted RNA genes.
