Physicochemical and Inflammatory Analysis of Unconjugated and Conjugated Bone-Binding Carbon Dots.

Carbon nanodots (CDs) have drawn significant attention for their potential uses in diagnostic and therapeutic applications due to their small size, tissue biocompatibility, stable photoluminescence, and modifiable surface groups. However, the effect of cargo molecules on CD photoluminescence and their ability to interact with tissues are not fully understood. Our previous work has shown that CDs produced from the acidic oxidation of carbon nanopowder can bind to mineralized bone with high affinity and specificity in a zebrafish animal model system.

The aims of this study were to quantify the rate of statin use among individuals with a history of coronary revascularization in a large, integrated health care system and to determine which demographic characteristics and clinical factors are associated with statin use.

Methods: This was a retrospective cohort study using database programming and chart review.

Long-term cardiovascular outcomes in survivors of Kawasaki disease.

Background And Objective: Kawasaki disease (KD) may result in coronary aneurysm formation, but there is incomplete knowledge regarding its long-term effects. Our objective was to quantify the longer-term rates of adverse cardiac events in a modern North American KD cohort.

Methods: Using the Kaiser Permanente Northern California population, we performed a retrospective cohort study in patients with a history of KD versus matched patients without KD.

Internal contamination by actinides after wounding: a robust rodent model for assessment of local and distant actinide retention.

Internal contamination by actinides following wounding may occur in nuclear fuel industry workers or subsequent to terrorist activities, causing dissemination of radioactive elements. Contamination by alpha particle emitting actinides can result in pathological effects, either local or distant from the site of entry. The objective of the present study was to develop a robust experimental approach in the rat for short- and long- term actinide contamination following wounding by incision of the skin and muscles of the hind limb.

Association of osteonecrosis and osteoporosis in HIV-1-infected patients.

Background: We questioned whether heightened impairment of regenerative capacity of osteoblasts might account for the excess of osteonecrosis and osteoporosis seen in HIV-infected patients. Were that the case, patients with osteonecrosis would have more osteoporosis than the patients without osteonecrosis.

Methods: Eleven thousand, five hundred and six patients with HIV infection were studied for the presence of osteonecrosis and osteoporosis and for confounding factors.

Stability of cryopreserved white blood cells (WBCs) prepared for donor WBC infusions.

Background: White blood cells (WBCs) collected from hematopoietic stem cell transplant donors are often given to the recipient to speed immune recovery or treat disease relapse. The postthaw recovery and viability of cryopreserved donor WBCs, stored for as long as 7 years, were assessed.

Study Design And Methods: Total nucleated cell (TNC) cell recovery, CD3+ cell recovery, and TNC viability were measured in 311 clinical donor WBC products: 168 products were unmanipulated or minimally manipulated and 143 products were extensively manipulated.

Preferential decorporation of americium by pulmonary administration of DTPA dry powder after inhalation of aged PuO(2) containing americium in rats.

After inhalation of plutonium oxides containing various percentages of americium in rats, we identified an acellular transient pulmonary compartment, the epithelial lining fluid (ELF), in which a fraction of actinide oxides dissolve prior to absorption and subsequent extrapulmonary deposit. Chelation therapy is usually considered to be poorly efficient after inhalation of actinide oxides. However, in the present study, prompt pulmonary administration of diethylenetraminepentaacetic acid (DTPA) as a dry powder led to a decrease in actinide content in ELF together with a limitation of bone and liver deposits.

A brief computerized self-screen for dementia.

Among his many contributions to the field of neuropsychology, Arthur Benton recognized the broad public health significance and unique ability of focused neuropsychological tests to screen for dementia. The need for validated screening tests for the presence of dementia will continue to grow as the cumulative prevalence of dementia grows and as our ability to treat or slow the progression of these diseases improves. We have developed a brief, self-administered computerized screening test for dementia, which is user friendly to the majority of elderly participants, including those with dementia.

A phantom for effective dose measurement: organ dose distribution assessment based on a numerical approach.

ICRP 60 has defined the personal dose equivalent Hp(10) as an estimator of the effective dose E. Personal dosimeters, worn on the trunk, allow the measurement of the quantity Hp(10). However, the characteristics of the instrumentation and the definition of Hp(10) itself can generate differences between the two quantities, depending on the energies and on the directional distribution of the incident radiation.

Feasibility study of extremity dosemeter based on polyallyldiglycolcarbonate (CR-39) for neutron exposure.

In nuclear facilities, some activities such as reprocessing, recycling and production of bare fuel rods expose the workers to mixed neutron-photon fields. For several workplaces, particularly in glove boxes, some workers expose their hands to mixed fields. The mastery of the photon extremity dosimetry is relatively good, whereas the neutron dosimetry still raises difficulties.

A tissue equivalent proportional counter filled with a mixture of tissue equivalent gas and 3He for neutron monitoring.

Tissue equivalent proportional counters (TEPC) allow the measurement of the ambient dose equivalent H(*)(10) in mixed fields. IRSN has been studying the design and the response of a TEPC in terms of neutron H(*)(10). First, a cylindrical counter was filled with propane gas at a low pressure.

Evaluation of dose equivalent by the electronic personal dosemeter for neutron 'Saphydose-N' at different workplaces of nuclear facilities.

This paper presents the results of measurements made with the electronic personal neutron Saphydose-N during the four campaigns of the European contract EVIDOS (EValuation of Individual DOSimetry in mixed neutron and photon radiation fields). These measurements were performed at Institute for Radiological Protection and Nuclear Safety (IRSN) in France (C0), at the Krümmel Nuclear Power Plant in Germany (C1), at the VENUS Research Reactor and the Belgonucléaire fuel processing plant in Belgium (C2) and at the Ringhals Nuclear Power Plant in Sweden (C3). The results for Saphydose-N are compared with reference values for dose equivalent.

Performance of the electronic personal dosemeter for neutron 'Saphydose-N' at different workplaces of nuclear facilities.

This paper mainly aims at presenting the measurements and the results obtained with the electronic personal neutron dosemeter Saphydose-N at different facilities. Three campaigns were led in the frame of the European contract EVIDOS ('Evaluation of Individual Dosimetry in Mixed Neutron and Photon Radiation Fields'). The first one consisted in the measurements at the IRSN French research laboratory in reference neutron fields generated by a thermal facility (SIGMA), radionuclide ISO sources ((241)AmBe; (252)Cf; (252)Cf(D(2)O)\Cd) and a realistic spectrum (CANEL/T400).

Simulations of the mean chord length of a multi-element TEPC irradiated by monoenergetic neutrons.

In recent years IRSN has developed tissue-equivalent proportional counters (TEPCs) for neutron monitoring. A detector with a multi-element geometry was studied for personal dosimetry purposes. The determination of the personal dose equivalent using a multi-element TEPC requires to calculate the mean chord length of the charged particles in the counter gas.

Performance of a cylindrical tissue-equivalent proportional counter for use in neutron monitoring.

Tissue-equivalent proportional counters (TEPC) allow the measurements of the absorbed dose and the ambient dose equivalent for neutron fields. A device based on this approach, called NAUSICAA((1,2)), has already been developed by IRSN to be used in high energy neutron fields for space applications. The response of this detector underestimates significantly the dose equivalent at low energies (several hundred keV) which represent the major component of neutron fields at workplaces in the nuclear industry.

Numerical and experimental results of the operational neutron dosemeter 'Saphydose-N'.

Since 1993, the Institute for Radiological Protection and Nuclear Safety (IRSN) has lead, in association with Electricité de France (EDF), a R&D study of a neutron personal electronic dosemeter. This dosemeter, called 'Saphydose-N', is manufactured by the SAPHYMO company. This paper presents first the optimisation of some detector components using Monte Carlo calculations, and second the test of the manufactured Saphydose-N under radiation following the IEC 1323 standard's recommendations for active personal neutron dosemeters.
