Association of the genomic instability score with HR-deficiency and platinum-response in ovarian cancer.
<p>(<b>A</b>) The distribution of score in <i>BRCA1</i> hyper-methylated patients is significantly higher than that in <i>BRCA</i> wild-type patients. (<b>B</b>) The distribution of score in HR-deficient patients (including <i>EMSY</i> amplification cases, and <i>PTEN</i>, Fanconi Anemia genes, <i>RAD</i> genes, <i>ATM</i>, <i>ATR</i> and <i>CHEK1/2</i> deficient cases) is significantly higher than that in other <i>BRCA</i> wild-type patients. (<b>C</b>) Association of the score with complete response (CR). The scores of all patients (nā=ā325) were divided into 12 equal intervals. The percentage of patients achieving a CR (according to the Response Evaluation Criteria in Solid Tumors) was calculated for patients in each interval and was plotted against each scoring interval in increasing order. Patients in high scoring interval show increasing likelihood of achieving CR. The dashed line represents linear regression line through the data points. (<b>D</b>) Same as (<b>C</b>) but calculating for platinum-status. 133 platinum-sensitive patients and 62 platinum-resistant patients were analyzed.</p
Clinicopathologic characteristics with different BRCA1/2 status.
<p>For categorical data (Tumor stage and grade, residual tumor size, response to chemotherapy therapy and platinum status), the Fisher exact test was used to calculate P value in <i>R</i>; for continuous variable such as age, the Wilcoxon rank sum test was used in <i>R</i>. Patients with debulking status āno macroscopic diseaseā are labeled as 0 cm in residual tumor size. Number (NO.) depicts the corresponding number of patients in each category. Missing values are excluded from the test analyses. BRCA wild-type cases do not include the BRCA1 methylation cases.</p><p>Clinicopathologic characteristics with different BRCA1/2 status.</p

Association of genomic instability with <i>BRCA1/2</i> mutations and survival in ovarian cancer.
<p>(<b>A</b>) Both <i>BRCA1</i> and <i>BRCA2</i> mutated tumors show elevated level genome mutations. High mutation group of <i>BRCA1/2</i> mutated ovarian cancer patients shows significantly improved survival than wild-type patients, whereas low mutation group of <i>BRCA1/2</i> mutated patients shows nonsignificant difference compared with wild-type patients. (<b>B</b>) Both <i>BRCA1</i> and <i>BRCA2</i> mutated tumors show increased copy number changes. High CNCs group of <i>BRCA1/2</i> mutated ovarian cancer patients shows significantly improved survival than wild-type patients, whereas low CNCs group shows nonsignificant difference compared with wild-type patients. (<b>C</b>) Both <i>BRCA1</i> and <i>BRCA2</i> mutated patients show increased genomic instability score, with <i>BRCA2</i> mutated patients show higher score distribution than <i>BRCA1</i> mutated patients. High scoring group of <i>BRCA1/2</i> mutated patients shows significantly improved survival than wild-type patients, whereas low scoring group shows nonsignificant difference compared with wild-type patients.</p

Experimental and Numerical Studies on a One-Step Method for the Production of Mg in the Silicothermic Reduction Process
In
this paper, a new efficient one-step technical method was first
developed for the production of magnesium in the industry. The one-step
method could combine the two processes of dolomite decomposition and
magnesium reduction in the magnesium reduction retort. Thus, the high-temperature
carbon dioxide produced by the dolomite decomposition process could
be collected in a timely manner instead of being emitted into the
atmosphere, and excessive heat loss caused by the two separate processes
also could be almost completely avoided. This paper presents an experimental
study on the intrinsic chemical kinetics mechanisms of this new efficient
one-step technology. By applying each of the most likely solid-state
kinetic models, the kinetic parameters of the two reactions that reacted
during the dolomite decomposition stage and magnesium reduction stage
were evaluated, and the kinetic models that best verify the experimental
data were attempted. For the dolomite decomposition stage of the one-step
technology, the equation of the chemical kinetic model can be represented
by Ī±<sup>2</sup>/2 = <i>k</i><sub>D1</sub>Ļ
in the temperature range of 1173ā1473 K, and the apparent activation
energy was determined to be 160.6 kJ mol<sup>ā1</sup>. For
the magnesium reduction stage of the one-step technology, the surface
reaction chemical kinetic model 1 ā (1 ā Ī²)<sup>1/3</sup>= <i>k</i><sub>S</sub>Ļ described very satisfactorily
the experimental values for the different reduction temperature. Then,
a one-step model incorporating the chemical reaction kinetics of the
dolomite decomposition stage and the magnesium reduction stage and
heat conduction was first developed. The simulations of the impact
of heating temperature on the dolomite decomposition stage and magnesium
reduction stage were carried out in the reduction retorts of the furnace
utilizing this model. The distribution of dolomite decomposition extent
in the retorts, the total extent of dolomite decomposition with time,
the distribution of magnesium reduction extent in the retorts, and
the total extent of magnesium reduction with time were studied in
detail. The analysis showed that the one-step technology is effective
in not only reducing the cycle time of dolomite decomposition stage
and magnesium reduction stage but also saving energy
