schwannomas are benign nerve sheath tumors that originate from any anatomical site. most of the schwannomas are found in the head, neck or limbs. schwannoma arising in a lymph node is extremely rare. we have found only four cases in the review of the literature. we experienced a case of intranodal schwannoma in a perigastric lymph node. a 72 year-old female underwent cholecystectomy due to clin...

Cotyledonary nodes taken alongwith shoot apex from seedlings of cotton (G. hirsutum) proliferated into shoots on nutrient agar medium supplemented with cytokinins. In the presence of optimal plant growth regulators, low light intensity enhanced the number of shoots initiated per explant in cotton. An average of 33.5 +/- 2.9 shoots were obtained from a single explant cultured for 8 weeks which i...

AIMS To determine whether it is necessary to support inferior retinal breaks with a scleral explant during pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RD). METHODS A prospective study was carried out on nine eyes of nine consecutive patients undergoing PPV for primary RD with associated inferior retinal breaks and no significant proliferative vitreoretinopathy. RESULT...

Introduction: Several radiotracers are being used for sentinel node mapping in patients with breast cancer. In the current study, we reported our experience with 99m-Tc Phytate for sentinel node mapping in Mashhad University of Medical Sciences. Methods: All breast cancer patients who underwent sentinel node mapping using 99m-Tc Phytate were included. All patients received intradermal peri-are...

Nowadays, the most rapid method for producing healthy and disease-free Lisiantus is micropropagation. With respect to high economic value of this plant which is regarded among the 10 top cutting flowers in the world, this research was carried out to suggest a suitable protocol for its in vitro propagation, using nodal sections as an explant. To carry out this object, the effects of the pH (5.5,...

AIMS Cultured cardiac explants produce a heterogeneous population of cells including a distinctive population of refractile cells described here as small round cardiac explant derived cells (EDCs). The aim of this study was to explore the source, morphology and cardiogenic potential of EDCs. METHODS Transgenic MLC2v-Cre/ZEG, and actin-eGFP mice were used for lineage-tracing of EDCs in vitro a...

in order to study, in vitro bud induction and shoot regeneration of different explants (shoot tip, axillary bud, hypocotyl and cotyledon) of henbane on ms medium enriched with various concentrations of kinetin (0, 1, 3 and 5 mg.l-1) alone or in combination with indole-3 acetic acid (0, 0.1 and 0.5 mg.l-1) this research was investigated in urom zist tak knowledge-based company plant tissue cultu...
