Marie Curie gave outstanding contributions to science and society that were recognized still in her lifetime. In particular, the discovery of radium completely changed the therapeutic methods for treatment of cancer and other diseases, and allowed the development of radiotherapy and nuclear medicine. Radium was also used in many non-medical applications. Radium applications fostered the growth ...

The efficient characterization of nuclear waste materials represents a significant challenge during nuclear site decommissioning, with a range of radionuclides requiring measurement in varied and often complex sample matrices. Of the available measurement techniques, inductively coupled plasma mass spectrometry (ICP-MS) has traditionally been applied to long-lived radionuclides, particularly in...

Although the development of radiolabeled antibodies for preclinical and clinical use in PET imaging continues to mature into a widespread technique (1–4), limitations still remain: namely space, in which the antigens to which our antibody is targeting are located (intracellularly or cell surface, bound or circulating), and time, the extended period after which the imaging must take place, to al...

Contamination of land could occur during the extraction and handling of materials containing high levels of naturally occurring radionuclide materials. These radionuclides find their ways into the food chain. The activity concentrations of natural radionuclides 40K, 226Ra, and 232Th in heart, liver, kidney, lungs, spleen and beef of cattle slaughtered and consumed in a tin mining area of Jos Pl...

Scenario of baryogenesis is considered in which primordial plasma starting from the Planck scale consists of primordial particles being the precursors of electrons and clusters of particles being the precursors of protons. Equilibrium between the precursors of protons and the precursors of electrons is defined by the proton-electron mass difference. At the temperature equal to the mass of elect...

Two critical processes in ovarian biology are the assembly of the primordial follicles early in development and then the subsequent development and transition of the primordial follicle to the primary follicle. These processes directly effect the number of oocytes available to a female throughout her reproductive life. Once the pool of primordial follicles is depleted a series of physiological ...

objective: the aim of this study was to evaluate the effect of sucrose on follicular survival rate and the incidence of apoptosis in rat ovarian tissue following vitrification. methods: ovaries of approximately 5-week-old female wistar rats were divided randomly into three groups: control (non-vitrified), vi (ethylene glycol + dimethyl sulfoxide) and vii (eg + dmso + 0.25 mol/lit sucrose). vit...

Primordial follicles steadily leave the arrested pool and undergo a primordial to primary follicle transition during the female reproductive lifespan. When the available pool of primordial follicles is depleted reproduction ceases and humans enter menopause. The present study was designed to investigate the actions of several growth factors previously identified as candidate regulatory factors ...

The study addresses accumulation of radionuclides by mushrooms and berry shrubs from the forest soil in the 30-km area around the MCC (the Krasnoyarskii Krai, Russia). The Suillus granulatus and S. luteus mushrooms have been found to be the best bioindicators in this area. The level of 137Cs concentration in these species can reach 10 kBq/kg dry mass. The 137Cs transfer factor (TF) by the mushr...

This review presents an overview of the successes and challenges currently faced in alpha radionuclide therapy. Alpha particles have an advantage in killing tumour cells as compared to beta or gamma radiation due to their short penetration depth and high linear energy transfer (LET). Touching briefly on the clinical successes of radionuclides emitting only one alpha particle, the main focus of ...
