In Southeastern Mexico, Centropomus undecimalis is an important fish species of sport and commercial fisheries for coastal and riverine communities. Fisheries along rivers and coasts depend on migratory habits of this species, and these movements are probably related to reproduction. In spite of its economic importance, few studies have been conducted focusing on its reproductive biology, and t...

fl uid content ( fi g. 2 ). This fi nding excluded the diagnosis of a hematoma and suggested the hypothesis of hydatidosis or congenital cyst of the spleen. Echinococcosis antibodies were negative so a defi nite diagnosis could not be made and surgical treatment was required. The splenectomy was performed by laparotomy. The spleen weighed 1,080 kg and the fl uid inside it was turbid and yellow ...

A new species is added to the monotypic African genus Djinga. Djinga cheekii Ghogue, Huber & Rutish.

Topmouth gudgeon, Pseudorasbora parva was firstly recorded in Europe in southern Romania and Albania. This species was firstly determined from the Thrace region of Turkey in 1984 in the River Meriç. In this research, samples collected from four different stations between March 2010 and June 2011. A total of 81 P. parva individuals were caught by using drift-nets with a mesh-size of 10 mm, and ...

The patients most often present widespead disease at diagnosis, with nodal and extranodal (bone marrow) involvement. Peripheral blood involvement is detectable by light microscopy in approximately 10% of the cases, but the majority of cases can be shown to have circulating malignant cells by sensitive molecular genetic methods. The disease usually runs an indolent course. Grade 3 FL may be char...
