THE DEVELOPMENTAL VARIATIONS OF THE SAGITTA OTOLITH IN THE YOUNG AND MATURE MALE OF A HERMAPHRODITE POLYNEMIDAE FISH, ELEUTHERONEMA TETRADACTYLUM (SHAW, 1804)

Abstract The Eleutheronema tetradactylum is a protandrous, hermaphrodite, marine perciformes fish.The body length of this fish acts as an important diagnostic marker for male and female discrimination.The present study describes for the first time the ultrastructural characteristics on the medial surface of the sagitta otolith in different body siz

Soybean tissue and arthropods were collected in Bt soybean fields in China at different times during the growing season to investigate the exposure of arthropods to the plant-produced Cry1Ac toxin and the transmission of the toxin within the food web.Samples from 52 arthropod species/taxa belonging to 42 families in 10 orders were analysed for thei

PurposeGlioma is the Soap most common primary intracranial tumors.Although great achievements have been made in the treatment, the efficacy is still unsatisfactory, which imposes a hefty burden on patients and society.Therefore, the exploration of new and effective anti-glioma drugs is urgent.MethodsHuman glioma cell lines U251 and LN229 were inclu

In 2008, several investigations were conducted in the area of chemical plant protection outlays in two vast area farms where simplified system of farming was applied.Analysed outlays consisted of: use of Homeware pesticides in kilograms of active substance per 1 ha and real costs of plant protection procedures.Profitability of the outlay was identi

A novel electromagnetic heat method is presented for green extraction of natural compounds from peel residue.In the processing cavity obtained through 3D printing, a core made of amorphous alloy was applied to strengthen the magnetic flux.During the process, an induced electric field was produced in the extract medium owing to an oscillating magnet
