RNAi-mediated knockdown of the voltage gated sodium ion channel TcNav causes mortality in Tribolium castaneum.

The voltage-gated sodium ion channel (VGSC) belongs to the largest superfamily of ion channels. Since VGSCs play key roles in physiological processes they are major targets for effective insecticides. RNA interference (RNAi) is widely used to analyse gene function, but recently, it has shown potential to contribute to novel strategies for selectively controlling agricultural insect pests.

Enhancement of microalgae growth and fatty acid content under the influence of phytohormones.

The growth of Scenedesmus obliquus improved with increase in phytohormones concentrations (10(-8)-10(-)(5)M). Indole-3-acetic acid (IAA) supported the maximum growth at 10(-5)M with 17.7×10(6)cells/mL and total fatty acid of 97.

Adolescent growth: genes, hormones and the peer group. Proceedings of the 20th Aschauer Soiree, held at Glücksburg castle, Germany, 15th to 17th November 2013.

The association between poverty, malnutrition, illness and poor socioeconomic conditions on the one side, and poor growth and short adult stature on the other side, is well recognized. Yet, the simple assumption by implication that poor growth and short stature result from poor living conditions, should be questioned. Recent evidence on the impact of the social network on adolescent growth and adult height further challenges the traditional concept of growth being a mirror of health.

Cytomegalovirus infection in pediatric allogenic hematopoietic stem cell transplantation. A single center experience.

We report a retrospective analysis of Cytomegalovirus (CMV) infection: incidence, recurrence, resistance, and subsequent disease of 81 children who underwent allogenic hematopoietic stem cell transplantation (HSCT). The recipient and/or donor's CMV serology was positive prior to transplant [recipient (R+) and/or donor (D+)]. CMV was monitored by RT-PCR starting from the first week post transplant.

Radioactive contamination of the atmosphere of Cairo, Egypt, from the Fukushima Dai-ichi nuclear plant accident.

Radioactive contamination in air dust particles of Cairo atmosphere from the Fukushima accident was detected by the gamma-ray spectroscopy technique. Analysis of the spectra obtained by using an High-Purity Germanium detector showed that there were some traces of (131)I and (134, 137)Cs. Estimate and study of concentration of those radionuclides were done over a period of about 5 months after the accident.

Accident dosimetry aims to evaluate the unplanned radiation doses delivered to individuals through one of the objects exist in the area of the accident. The gamma dose response of free radicals generated in irradiated aspartame tablets and its usability for emergency dosimetry was studied. EPR spectra of unirradiated and irradiated aspartame-based sweetener were recorded.

The spectrum of inherited bleeding disorders in pediatrics.

Inherited bleeding disorders (IBDs) are caused by quantitative and qualitative alterations of either platelets or plasma proteins involved in coagulation and fibrinolysis. Hemophilias are the most frequent IBDs; however, accumulated data from various studies reported that von Willebrand disease (VWD) is the most common cause of IBD, with an increased incidence of platelet function defects, mostly due to the increased rate of consanguinity in some communities. VWD is an inherited disorder of homeostasis due to quantitative or qualitative defect of von Willebrand factor.

Mycotoxins and child health: the need for health risk assessment.

The occurrences of mycotoxins as food contaminants in different localities particularly in developing countries and the inevitable exposure of populations and children to these toxins with probable adverse outcomes need be scientifically and systematically assessed. Health risk assessment developed in the 1980s is separate from risk management, both with risk communication form the risk analysis framework adopted by the World Health Organization. The process contributes increasingly to policy development, public health decision making, the establishment of mycotoxin regulations and research planning.
