How Proper Packaging Improves the Shelf Life of Medical Devices
Medical devices are incredibly important in today’s world. They play a significant role in the treatment and prevention of various medical conditions. However, their effectiveness can be compromised if they are not packaged correctly. Packaging is an essential component of maintaining the integrity and shelf life of medical devices, especially during transportation and storage. Read on ...

Tungsten tube-High density & melting point metal tube
Tungsten tubes are drilled from tungsten bars / rods, W tube with massive OD are going to be mold directly. Tungsten – periodic symbol W - lays claim to the very best freezing point of all components. This characteristic combined with a superb ability to resist thermal shock enhances its ability to perform well as a conductor. Rocket cones, that should stand up to fast temperature changes ...

Transcriptional expression of H2B, CTP synthase and PLK3 genes in whole blood exposed to 60Co gamma radiation
Ionising radiation induces complex molecular responses in human cells resulting in changes at mRNA and protein expression. Limited data is available on the transcriptional status of functional genes in response to ionising radiation using peripheral blood mononuclear cells (PBMCs). In the present study, transcriptional profiles of Histone 2B, CTP synthase and PLK3 were studied. Blood samples were ...

Assessment of absorbed dose in digital and MIRD phantoms by MCNP in thorax area
This paper describes the development of mathematical models, called phantoms, for the assessment of absorbed doses caused by internal radionuclides. In more developed phantoms, anatomical models based upon 3D imaging methods are used. Cross-sectional anatomical models consist of numerous arrays of voxels, each of which individually corresponds to an organ. The digital phantom presented in this ...

Chromosomal aberrations induced by a low dose of neutron irradiation and hyperthermia
The purpose of this study was to investigate the effect of Hyperthermia (HT) on the Frequency of Chromosomal Aberrations (FCA) induced by a low dose of neutron irradiation. Blood samples were exposed to HT, 6cGy neutrons, HT + neutrons and neutrons + HT, and the FCA was scored in metaphase. HT alone at 41.5°C had no effect on FCA; however, the FCA was significantly higher at 43°C (p Keywords: low ...

Analysis of low-angle X-ray scattering profiles from irradiated blood samples
The Transfusion-Associated Graft-Versus-Host Disease (TA-GVHD) is a serious potential complication of blood transfusions that is essentially prevented by blood product irradiation. In this study, scattering profiles from lyophilised and irradiated samples of plasma (PL) and formed elements (MC) were compared with non-irradiated ones. Fresh blood specimens were obtained from volunteers by vein ...

Re-examining the health effects of radiation and its protection
The health effects of radiation from atomic explosions in Japan were completely different from those due to radiation from the Co-60 contaminated apartments in Taiwan. The sudden exposure to acute radiation in extremely high doses killed Japanese people, and harmed the survivors in lower doses as shown by increased cancer mortality, especially the leukemia based on the LNT model. The chronic ...

ICT based training on nuclear technology applications in Tanzania
Peaceful application of nuclear technology has contributed to socio-economic resource development in Tanzania. The Tanzania Atomic Energy Commission has taken some active steps for the incorporation and or adoption of ICT-based training modules in nuclear science and technology and its applications. The overall objective of this programme is to establish a sustainable national capability for ...

Analysis of breast cancer in the Massachusetts TB fluoroscopy cohort and in the Japanese A-bomb survivors, taking account of dosimetric error and curvature in the A-bomb dose response: absence of evidence of reduction of risk following fractionated i
Breast cancer has occurred in excess among women exposed briefly to atomic bomb radiation and among those exposed repeatedly over many years to medical radiation for tuberculosis (TB). The breast cancer excess is strongly dependent on age at exposure, with risk highest among the young and small or non-existent when exposure occurs past the menopausal ages. The linear excess relative risk ...
