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...

Immature zygotic embryo explants of Carica papaya were cultured on MS medium supplemented with 2,4-D (2.0 mg/l) and formed globular embryos on explants without callus formation in 4-6 weeks. Maturation and conversion of somatic embryos was also achieved on the same medium. Cotyledonary stage embryos germinated to 63.66 and 68.33% in cv. honey dew and washington respectively in MS basal medium s...

An efficient protocol was developed for high frequency plant regeneration from leaf explants of Ammi majus. Ammi majus L. (Apiaceae) is a herb of pharmaceutical as well as ornamental interest and used in the treatment of leucoderma. Since in Ammi majus the seed set and germination is poor attempts were made to propagate the plants through tissue culture. The callus from cotyledonary leaves obta...

A method of estimating the magnitude and distribution of umbilical blood flow by means of radioactive microspheres in sheep fetuses in utero is described. Simultaneous measurements of total umbilical flow by this method and the steady-state diffusion technique showed agreement within ± 11%. In 11 fetuses of 90 to 150 days gestational age, the distribution of umbilical flow to the intercotyledon...

in this study 121 prescapular, prefemoral and popliteal lymph node of male healthy camel from mashhad abattoir were collected. after collecting of specimens factors such as: length, width, thickness, weight, volume and density of each lymph node were measured by caliper device. all factors were analyzed and compared using excel program. it was revealed that, normal dimensions of right prescapul...

Ewe abortion and neonatal mortality are serious problems to sheep farmer. The objective of this paper was to report isolation of Erysipelothrix rhusiopathiae from aborted fetuses in a flock in Tehran, Iran. Abortion occurred in 10% of ewes in the flock. The fetuses were well developed and pinpoint, necrotic-like lesions were recorded on the placental cotyledons, whilst the inter -cotyledonary a...

Density-labeling with 10 millimolar K(15)NO(3)/70% (2)H(2)O has been used to investigate isocitrate lyase synthesis during greening of sunflower (Helianthus annuus L.) cotyledons when the glyoxysomal enzyme activities sharply decline and the transition in cotyledonary microbody function occurs. A density shift of 0.0054 (kilograms per liter) was obtained for the profile of isocitrate lyase acti...
