The predictors of adj-RT use included African-American race, more advanced stage, higher grade, presence of lymphovascular invasion, and ER/Her-2 positivity for the entire cohort and increased age, urban location and higher income for BCS. Adj-RT was associated with lower mortality in the propensity matched model (overall HR for BCS=0.28, p-value<0.001; overall HR for MS=0.62, p-value=0.001).

This study demonstrates that while adj-RT after BCS is associated with decreased mortality in MBC patients, adj-RT is omitted in up to a third of cases of MBC after BCS despite being standard of care.

Serious toxicity associated with sunitinib is a rare situation. However; there are few cases reported in the literature. As a result of the inhibition that is caused by sunitinib malate agent at the receptor level, vascular endothelial growth factor (VEGF) level increases. These increased VEGF levels are considered to having a positive contribution on neurological side effects. Neurotoxicity that is related with the usage of sunitinib malate for two weeks will be presented in this case report.Dissolution fluxes of stable (127I) and radioactive (129I) isotopes of iodine from a brackish lake sediment beside a spent nuclear fuel reprocessing plant in Japan were evaluated through two kinds of experiments incubation using a sediment core sample for 24 h, and observation of 127I and 129I concentrations in sedimentary pore water. For 127I, the dissolution flux evaluated in the incubation experiment was comparable with that obtained from the vertical gradient of 127I concentration in pore water in the observation experiment. This suggests that degradation of organic matter in the surface sediment is an important source of dissolved 127I found in the water. For 129I, the dissolution flux estimated in the incubation experiment showed negative values, indicating the transfer of 129I to the sediment from the overlying water (i.e., absorption). Moreover, the flux evaluated from the observation experiment was positive. This result suggests that degradation of organic matter in the surface sediment is scarcely important to the supply of 129I from the sediment to the water in the studied lake. The dissolution flux of 129I estimated in the observation experiment was smaller than the absorption flux of 129I in the incubation experiment. This potentially indicates that the dissolution of sedimentary 129I does not significantly change 129I concentrations in the water and sediment of the lake. This hypothesis was consistent with previous research conducted for the studied lake.The uptake of radionuclides by plants and their subsequent relocation to the human body through ingestion is one major pathway of human internal exposure. Thus, the present study was conducted to examine the levels of natural radionuclides, 238U and 232Th, in soil of Ezillo paddy fields (field 1 and field 2) at depths 0-4 cm and 4-8 cm, their transfer and accumulation in rice grains. The mean concentrations of both radionuclides in the soil were clearly greater than the UNSCEAR estimated worldwide average while that of the rice with values of 11.7 ± 4.3 and 3.0 ± 1.3 Bq/kg in field 1 and 8.5 ± 4.2 and 4.3 ± 1.6 Bq/kg in field 2 for 238U and 232Th respectively, were well below the worldwide average. The radionuclide transfer factors (TFs) across both depths ranged from 0.03 to 0.67 and 0.01 to 1.20 for 238U and 232Th respectively. The overall geometric means and geometric standard deviations of the TF estimated in field 1 were respectively 0.22 and 1.52 for 238U and 0.18 and 4.21 for 232Th (soil,0-4cm); 0.43 and 1.80 for 238U and 0.18 and 3.79 for 232Th (soil,4-8cm) whereas in field 2 the values were respectively 0.12 and 2.62 for 238U and 0.06 and 4.15 for 232Th (soil,0-4cm); 0.11 and 1.85 for 238U and 0.12 and 4.15 for 232Th (soil,4-8cm). The nuclide concentrations in the rice and the present TFs are within the ranges of values in the literature.The main techniques of animal product sampling used in different time periods after the Chernobyl accident are summarised and lessons learned from this analysis are presented. It was shown that simple instruments for measurement γ-radiation in the environment can also be effectively implemented for measurement of γ-emitters in animal products even though these were not originally developed to measure radioactivity in food. The lessons learned related to the major tasks of the monitoring such "what to sample", "where to sample" and "when to sample". The role and example of application of supplementary data on radionuclide of concern properties for sampling planning are also discussed. Based on the statistical analysis of the data obtained in the affected settlement it was shown that radionuclide concentration in the animal products can be fitted by the log-normal distributions whilst the dispersion of the logarithms of the activity 137Cs concentrations in milk is not dependent on the local settlement specific factors. Based on these findings the novel approach for justification of the number of samples that should to be taken to obtain the GM estimate with predefined precision for given variability of the data is suggested.Mycobacterium tuberculosis H37Ra (Mtb-Ra) ORF MRA_1916 is annotated as a D-amino acid oxidase (DAO). These enzymes perform conversion of d-amino acids to corresponding imino acids followed by conversion into α-keto-acids. In the present study Mtb-Ra recombinants with DAO knockout (KO) and knockout complemented with DAO over-expressing plasmid (KOC) were constructed. The growth studies showed loss of growth of KO in medium containing glycerol as a primary carbon source. Substituting glycerol with acetate or with FBS addition, restored the growth. Growth was also restored in complemented strain (KOC). KO showed increased permeability to hydrophilic dye EtBr and reduced biofilm formation. Also, its survival in macrophages was low. learn more Phagosome maturation studies suggested enhanced colocalization of KO, compared to WT, with lysosomal marker cathepsin D. Also, an increased intensity of Rab5 and iNOS was observed in macrophages infected with KO, compared to WT and KOC. The in vivo survival studies showed no increase in CFU of KO.
