In this study, we investigated the phytotoxicity of gold nanoclusters (AuNCs) on seed germination capacity, physiological response to stress and uptake, transport nanomaterials in broad beans. Although similar findings were observed for AuNCs bean root tip cells between micronucleus assays traditional experiments, former was more sensitive rapid. At experimental concentrations 0–200 mg/L, toxic...

potassium (k) is an element essential for plant growth, playing a significant role in physiological and biochemical processes in plant. the relationship between a soil testing extractant vs. plant nutrient uptake should be a determining parameter in the selection of a soil testing method. the objective of this study was to evaluate different extractants employed for extracting available k in 10...

Methods of determining insulin sensitivity that use an oral challenge of glucose are preferred to those using intravenous administration since the measurement is made in conditions more akin to normal physiology. One previously reported protocol (ODILE) studies glucose uptake in isolation from absorption and endogenous production by the intravenous administration of tracer approximately forty-f...

increased metabolic activity in muscle secondary to excessive muscle activity during the uptake phase and shortly before fdg injection is a known phenomenon. we present fdg pet/ct findings in a young male, known case of carcinoma maxilla his scan showed diffuse increased metabolic activity in multiple skeletal muscle groups. there was history of unaccustomed, strenuous sports activity of skiing...

The neuromodulator serotonin is an important regulator of aggressive behavior in vertebrates. Experimentally increasing synaptic levels of serotonin with fluoxetine, a selective serotonin reuptake inhibitor, has been shown to reliably decrease the expression of aggressive behavior. Here, we describe a method by which fluoxetine can be noninvasively administered to male Betta splendens (an attra...

Incidental (18)F-2-fluoro-2-deoxyglucose (FDG) uptake in blood vessel walls is sometimes demonstrated during routine oncologic imaging with positron emission tomography/computed tomography (PET/CT). FDG uptake in vessel walls can also be seen under some non-physiological conditions such as vasculitis and arteriosclerosis. Radiologists need to be aware of the diseases which can exhibit FDG uptak...

18 F-FDG PET/CT is an integral part of modern-day practice, especially in the management individuals presenting with malignant processes. The use this novel imaging modality oncology has been rapidly evolving. However, due to its detection cellular metabolism, it not truly tumor specific. also used infective and inflammatory disorders. One challenges experienced correct differentiation abnormal...

The aim of the study was to assess the effects of climbing ability and slope inclination on vertical loading both in terms the forces involved and physiological responses. Five novice and six intermediate female climbers completed a climbing route at three slope inclinations (85°, 90°, and 98°). The vertical loading during the climb was assessed by force-time integral using a Novel Pedar-X inso...

The route of NO(2)(-) uptake and subsequent physiological effects were examined in the marine teleost, European flounder (Platichthys flesus), during exposure to 1 mM ambient NO(2)(-) for up to 11 days. Drinking of seawater resulted in a similar nitrite concentration in the anterior part of the intestine as in the ambient water. The NO(2)(-) concentration decreased along the gastro-intestinal t...
