Risks from electromagnetic devices are of considerable concern. Electrohypersensitive (EHS) persons attribute a variety of rather unspecific symptoms to exposure to electromagnetic fields. The pathophysiology of EHS is unknown and therapy remains a challenge. We hypothesized that some electrosensitive individuals are suffering from common somatic health problems. Toward this end we analysed clinical laboratory parameters including thyroid‐stimulating hormone (TSH), alanine transaminase (ALT), aspartate transaminase (AST), creatinine, hemoglobine, hematocrit and c‐reactive protein (CRP) in subjects suffering from EHS and in controls that are routinely used in clinical medicine to identify or screen for common somatic disorders. One hundred thirty‐two patients (n = 42 males and n = 90 females) and 101 controls (n = 34 males and n = 67 females) were recruited. Our results identified laboratory signs of thyroid dysfunction, liver dysfunction and chronic inflammatory processes in small but remarkable fractions of EHS sufferers as potential sources of symptoms that merit further investigation in future studies. In the cases of TSH and ALT/AST there were significant differences between cases and controls. The hypotheses of anaemia or kidney dysfunction playing a major role in EHS could be unambiguously refuted. Clinically it is recommended to check for signs of treatable somatic conditions when caring for individuals suffering from self‐proclaimed EHS.

We induced somatic embryogenesis from the cotyledon segments ofOlea europaea (L) cvs. ‘Chetoui’, ‘Chemleli’, and ‘Arbequina’. Calli were established from all three cultvars on OMc media supplemented
with IBA and 2i-R The greatest success was obtained with media that contained zero or low concentrations of growth regulators.
High levels of hormones (i.e.,>0.5 mgL-1 IBA and 2i-P) inhibited embryogenesis. Embryos at different maturation stages were observed with continuously proliferating
secondary embryogenesis. Abnormally shaped embryos and teratoma were also noted. Four weeks was the optimal incubation period
for inducing embryogenesis on the auxin-containing medium. In addition, 30 to 40 gL-1 sucrose was more effective than glucose in stimulating the growth and maturation of somatic embryos. Embryogeic efficiency
was also higher when multivariate combinations of nitrogen sources (inorganic and organic nitrogen forms) were used. The plantlets
that were derived from our germinating somatic embryos were similar to those obtained from axillary buds. 相似文献

Somatic embryogenesis of olive Olea europaea (L.) ‘Chetoui’ was studied using cell suspension cultures initiated from mature leaf-derived calli. Calli were developed
on half-strength MS medium supplemented with 10 μM NAA and 2.25 μM 2i-P in the dark. Different combinations of three plant
growth regulators (2,4-D, NAA and zeatin) were tested to determine cell proliferation and somatic embryogenesis induction
and differentiation. Embryogenic suspension cultures were established in olive-modified medium for embryogenesis (OMe) containing
2.5 μM 2,4-D and 2.5 μM zeatin. Pre-globular and globular embryos were induced from mature olive tissue in liquid medium.
In addition, the nitrogen form as inorganic (reduced; (NH4)2SO4 or oxidized; KNO3) and organic (CH) was used separately or in combination to improve the cell growth and proliferation. The most effective
growth rate and cell proliferation were obtained with the medium containing inorganic and organic nitrogen forms. 相似文献
