Previous analysis of an Australian population of D. melanogaster revealed two predominant Est6 promoter haplotypes, P1 and P7. These haplotypes, which differ at 14 sites over a 325-bp region, are associated with a 15-20% difference in male EST6 activity. Here we show that the P1/P7 sequence difference causes the male activity variation by recreating the activity difference among >60 independent...

Supramontana argentina sp. nov. (Platyhelminthes, Continenticola, Geoplanidae) from north-eastern Argentina is herein described. The new species differs from Supramontana irritata Carbayo & Leal-Zanchet, 2003 from Brazil, the only species of this genus so far described, by external and internal morphological characters. Supramontana argentina sp. nov. is characterized by having a colour pattern...

Structural changes were examined in liver tissue from 28 patients with chronic bile duct obstruction in whom portal hypertension was diagnosed. Extrahepatic portal occlusion was found in three patients and cirrhosis of the liver in two. In the remaining 23 patients diffuse hepatocyte hyperplasia and portal fibrosis were observed, but a normal spatial relation between portal tracts and hepatic v...

ABSTRUCT The authors prepared the obstructive jaundice model on which the external biliary drainage was operable, and tried to clarify the critical duration of obstruction from the aspects of the standard liver function and hepatic fibrosis, and the following results were obtained. 1) The T. B, Al-p, GOT and GPT levels in 1 to 4 weeks after the common bile duct obstruction was significantly hig...

BACKGROUND Contamination of the conjunctiva in association with nasolacrimal duct obstruction is by all accounts a risk factor for infectious endophthalmitis post-cataract surgery. METHODS All patients who underwent cataract day surgery routinely received nasolacrimal duct syringing with normal saline at the Wakayama Medical University Hospital, Japan, from 2011 to 2013. The microorganisms is...

Background: Malignant biliary and/or pancreatic obstruction has often encountered in the advanced stages of periampullary and cholangicarcinomas. HabibTM Radiofrequency (RF) ablation has been successfully used in the management of various cancers of liver and pancreas. Percutaneous HPB probe (EMcision Ltd, London, UK) is a new addition to this class of tools. It is an endoluminal Radiofrequency...

This paper describes the occurrence of digenetic Rhipidocotyle santanaensis Lunaschi, 2004 in Brazil. This parasite was found in the liver, heart, gonads, intestine, pyloric caeca, stomach, swim bladder and cavity of Acestrorhynchus lacustris (Lütken, 1875) from the Batalha River, São Paulo State, with higher incidence in gonads and digestive tract. The parasite specimens found in this study sh...

The male reproductive system includes the gonads (testes), a series of specialized ducts (the epididymis, ductus deferens, ejaculatory duct, and urethra), accessory glands (the seminal vesicles, prostate, and bulbourethral glands), and the external genitalia (penis and scrotum). The female reproductive system includes the gonads (ovaries), derivatives of an embryonic system of ducts (the uterin...
