This is an application for an adjuvanted, inactivated vaccine against avian influenza. This disease occurs worldwide and not only affects domestic poultry, but also infects a wide range of feral birds covering 88 species and 22 families, occurring most prolifically in migratory waterfowl. Type A influenza virus can also infect various species of mammals (including humans). The main reservoir of...
The best available marker for epithelial ovarian cancer is still considered to be CA-125 due to a combination of reliability and general availability. HE4 is more sensitive than specific than CA-125, however the former is not in routine use. NICE still therefore recommends CA-125 rather than HE4. CA-125 is used for the diagnosis of epithelial ovarian cancer. αFP and βHCG are useful for identify...
Absolute 108Agm characterization based on gamma-gamma coincident detection by two NaI(Tl) detectors.
A two-dimensional analysis of three coincident gamma-rays in (108)Ag(m) decay, detected by two NaI(Tl) scintillation detectors, allows a direct measurement of the source activity. A modification of the Eldridge-Crowther formulas derived originally for (125)I was done recently for the case of two coincident gamma-rays in (60)Co decay (Volkovitsky and Naudus, 2009). A similar approach is applied ...
We read with interest the editorial by Chung discussing advantages of radio-guided occult lesion localisation (ROLL) over other commonly used pre-operative localisation techniques for breast tumours. While the results from our audited introduction of ROLL support the conclusion that ROLL is “a simple and effective solution for guiding the excision of impalpable breast lesions”, two important dr...
Brachytherapy, is a method to treat prostate cancer in which a radiation source is placed inside or next to the cancer affected tissues. Purpose of this article is to determine the uncertainty level of received dose in prostate tissue due to the relocation of the placed radiation sources and inflation in prostate after positioning the radiation seeds. To simulate the model 6711 Amersham (activi...
The CITATION code based on neutron diffusion theory is used for flux calculation inside voluminous sample in prompt gamma activation analysis with an isotopic neutron source (241Am–Be). The code used the specific parameters related to energy spectrum source, irradiation system materials (shielding, reflector, etc.), geometry and elemental composition of the sample. The flux distribution (therma...
Ovarian cancer continues to be a major health threat for women. The American Cancer Society estimates that in the United States in 1998, 25 400 new cases will be diagnosed and 14 500 women will die as a result of this disease (1). Most of these cancers are epithelial in origin, as germ cell tumors of the ovary represent only ;5% of the total. Approximately 70% of epithelial ovarian cancers will...
Thyroid hormone acts on a wide range of tissues. In the cardiovascular system, thyroid hormone is an important regulator of cardiac function and cardiovascular hemodynamics. Although some early reports in the literature suggested an unknown extrathyroidal source of thyroid hormone, it is currently thought to be produced exclusively in the thyroid gland, a highly specialized organ with the sole ...
Studies of the mouse C-1300 neuroblastoma were undertaken in order to isolate tumor-specific antibodies and harness them for detection of tumors in vivo. Preliminary investigations demonstrated the strain-growth specificity of the neuroblastoma in A/Jax male mice and established the requirement for tumor viability for successful adoptive passage. Intradermally passaged tumor permitted extended ...
زمینه و هدف : اپیدمی جهانی سل منجر به 2 میلیون مورد مرگ و9 میلیون موارد جدید بیماری در سال میشود. اکثریت بیماران مبتلا به سل در کشورهای در حال توسعه زندگی می کنند،که در این کشورها تشخیص سل بر اساس مشخص شدن باسیل اسید فاست بر روی گستره های آماده شده خلط با میکروسکوپ نوری ساده داده می شود. تشخیص بوسیله میکروسکوپ در کشورهایی که اندمیک برای سل هستند ویژگی بالایی دارد،ولی حساسیت نسبتا پایینی دارد ...
