introduction : comorbidity is a new term in psychiatric nosology which despite its expansive use is not clearly defined. overlapping of axis i and axis ii disorders in multiaxial system of dsm and controversy over which disorders belong to which axis, have also complicated the issue. a number of studies investigating patterns of comorbidity for axis i and axis ii disorders could not find a one ...

OBJECTIVES Continuous femoral nerve blocks provide effective analgesia after knee arthroplasty, and infusion effects depend on reliable catheter location. Ultrasound-guided perineural catheter insertion using a short-axis in-plane technique has been validated, but the optimal catheter location relative to target nerve and placement orientation remain unknown. We hypothesized that a long-axis in...

many factors may influence the efficiency of somatic embryogenesis. this capability may be differ with regard to media compositions, genotype, tissue, organ ontology and the stage of differentiation. the effects of five salicylic acid concentrations (0, 25, 50, 75 and 100 mm) on different stages of carrot somatic embryogenesis were studied using petiole and root secondary phloem explants as sta...

one of the well-known herbal drugs is henna (lawsonia inermis). according to the components in henna, several beneficial properties (i.e., antimicrobial, anti-inflammation, wound healing, trypsin inhibitory and antioxidant) have been reported. the present study was designed to investigate the effects of two natural substances (sodium chloride and henna extract) on experimental skin lesion due t...

This paper proposes a modified dynamic equivalent circuit model for linear induction motor considering both longitudinal end effect and transverse edge effect. The (speed-dependent effect) is based on conventional Duncan’s approach. investigated by using three correction factors applied to the secondary resistance magnetizing inductance. Moreover, iron saturation effect, skin air-gap leakage ar...

A number of processes operating during the first cell cleavages enable the left-right (LR) axis to be consistently oriented during Xenopus laevis development. Prior work showed that secondary organizers induced in frog embryos after cleavage stages (i.e. conjoined twins arising from ectopic induced primary axes) correctly pattern their own LR axis only when a primary (early) organizer is also p...

In amphibian embryos, establishment of dorsal-ventral asymmetry is believed to involve dorsal-ventral differences in vegetally derived mesoderm-inducing signals and/or differences in the competence of animal hemisphere (ectodermal) cells to respond to these signals. Previous studies have shown that certain Wnt proteins can generate an ectopic dorsal axis when misexpressed, and that they do so b...
