In this study, the sorption of Malachite green (MG) on Hydrilla verticillata biomass, a submerged aquatic plant, was investigated in a batch system. The effects of operating parameters such as temperature, adsorbent dosage, contact time, adsorbent size, and agitation speed on the sorption of Malachite green were analyzed using response surface methodology (RSM). The proposed quadratic model for...

The composition of the diets of 66 species of fishes was investigated from September 2009 to June 2010 in three subsystems of the Upper Paraná River floodplain (Brazil), following invasion by the two mollusk species Limnoperna fortunei (Dunker, 1857) and Corbicula fluminea (Müller, 1774), and the macrophyte Hydrilla verticillata (L.f.) Royle. Limnoperna fortunei was consumed in all three subsys...

Salvia divnorum (an intense hallucinogen) is currently illegal in New Zealand under the 2014 Psychoactive Substances Amendment Act. Despite this, there is a scarcity of research surrounding Salvia divinorum and its effects in a New Zealand context. To explore the experiences of Salvia divinorum users, an anonymous questionnaire was advertised through flyers placed in locations where young adult...

Fabry disease is an X-linked disease of glycosphingolipid (GL) metabolism. The accumulation of GL in tissues can affect multiple organ systems. Initial symptoms includes episodes of severe pain in the extremities, cornea verticillata and skin lesions. In late stages, kidney, heart and brain can be involved. This report attempts for importance of cornea verticillata in the diagnosis of Fabry dis...

Aquatic macrophytes have been widely studied because of their capability of absorbing contaminants from water and their subsequent use in biomonitoring. This study presents a comparison of Cr accumulating potential of submerged aquatic plants viz Vallisneria spiralis and Hydrilla verticillata. These plants were treated with various concentrations of treated tannery effluent collected from UASB,...

The submersed monocot Hydrilla verticillata (L.f.) Royle is a facultative C(4) plant. It typically exhibits C(3) photosynthetic characteristics, but exposure to low [CO(2)] induces a C(4) system in which the C(4) and Calvin cycles co-exist in the same cell and the initial fixation in the light is catalyzed by phosphoenolpyruvate carboxylase (PEPC). Three full-length cDNAs encoding PEPC were iso...

Submerged macrophytes are subjected to potential mechanical stresses associated with fluctuating water levels in natural conditions. However, few experimental studies have been conducted to further understand the effects of water level fluctuating amplitude on submerged macrophyte species and their assemblages or communities. We designed a controlled experiment to investigate the responses of t...

Soil salinity is one of the most important abiotic stress factors affecting agricultural productivity in arid and semi-arid regions. Salinity negatively affects soil as well causes negativity plants grown on it. In exposed to salt stress, processes such germination, emergence sprout are affected, many morphological physiological negativities plant develops mechanisms that can tolerate these neg...

BACKGROUND Salvia divinorum is a non-water-soluble hallucinogen that is becoming increasingly popular among adolescents. Salvia is a highly selective full agonist of primate and cloned human cerebral kappa-opioid receptors, although its psychotomimetic effects are similar to serotonergic agonists and NMDA glutamate antagonists. Salvia has been associated with depersonalization, laughter, feelin...
