background: from the time immemorial man has been exposed to ionizing radiation from the environment in which he lives. radiation protection concepts and philosophy have been evolving over the past several decades. materials and methods: the radioprotective of effect of aloe vera leaf extract (1000 mg /kg b.wt. orally for 15 consecutive days) has been studied against 6 gy of gamma radiation in ...

in this study the original mitotic chromosome counts are presented for 5 onobrychis species of o. sect. onobrychis in iran, 2n = 2x = 14 for o. persica, 2n = 4x = 28 for o. viciifolia, 2n = 4x = 28 for o. altissima, 2n = 2x = 14 for o. shahpurensis and 2n = 2x = 14 for o. sosnovskyi. the basic chromosome numbers of all studied taxa are consistent with the proposed base number of x = 7. in addit...

BACKGROUND Mitotic rate is routinely assessed in breast cancer cases and based on the assessment of 10 high power fields (HPF), a non-standard sample area, as per the College of American Pathologists cancer checklist. The effect of sample area variation has not been assessed. METHODS A computer model making use of the binomial distribution was developed to calculate the misclassification rate...

The purpose of the major cancer research project of Barnard Hospital is to measure the properties of epidermis during epidermal carcinogenesis induced by methylcholanthrene, to integrate the findings and thus to construct a comprehensive account of what .happens (6). Mitotic frequency is one of these properties and has been investigated by Cooper and Relier (5) and by Reller and Cooper (12). Th...

Original meiotic or both and mitotic chromosome numbers are reported for ten endemic one non species in nine vascular plant families from Iran. The of Acantholimon schahrudicum, A. truncatum, Anthochlamys multinervis, Campanula perpusilla, Cousinia calcitrapa var. interrupta, Dorema ammoniacum, Euphorbia gedrosiaca, Hyocyamus orthocarpus were determined the first time. counts Astrodaucus persic...

INTRODUCTION Mitotic Activity Index (MAI) is an important independent prognostic factor and an integral part of the breast cancer grading system. Thus, correct estimation of this prognostically relevant feature is essential for guiding treatment decision and assessing patient prognosis. The aim of this study was to validate the use of high resolution Whole Slide Images (WSI) in estimating MAI i...

PGC counts were carried out on larvae of Pleurodeles waltl (urodele amphibia) issued from standard, monosexual male and monosexual female offspring while the genital ridges were settling. During this period, which is characterized by a zero mitotic index (and is therefore called the Po period), and which lasts from stage 35 to stage 41, no PGC proliferation occurs. A statistical analysis indica...

The increased use of biostimulants in conventional agriculture and organic farming requires the implementation rapid tests to determine their effectiveness enhancing plant growth protection against abiotic stresses. However, innocuity health has rarely been demonstrated. We used Vicia faba Micronucleus Assay, as described by standard AFNOR EN ISO 29200(2020-05) reveal biostimulant, genotoxic cy...
