The objective of this work was to concentrate, through a membrane separation process, the fatty acids from oil/solvent mixture. The oil was obtained by ultrasound-assisted extraction from freeze-dried cells of Mortierella isabellina. The concentration of the fatty acids was investigated using flat-sheet polymer membranes of ultrafiltration and nanofiltration. The effects of temperature and pressure were evaluated by the retention of the fatty acids. Oil retentions between 45.23 and 58.20% to ultrafiltration membrane and 43.50 and 56.00% to nanofiltration membrane were observed. The best condition for the ultrafiltration membrane was 4 bar and 40 °C and for nanofiltration membrane was 12 bar and 50 °C. The oil contains a high concentration of oleic acid and palmitic acid that is a desirable property for the biodiesel production. The results showed the applicability of this technology in the solvent recovery step whereas the oil recovered contains a high concentration of fatty acids.Numerous eligible articles investigated the potential impact of the promoter region of UCP2 (rs659366) variant and the susceptibility for obesity with questionable outcomes. Our team designed this case-control combined with meta-analysis survey to illustrate the contribution of this variant with obesity. This case-control survey was formulated based on 110 obese Egyptian patients and 122 non-obese controls. Genomic DNA was amplified for ascertaining of UCP2 (G-866A; rs659366) variant exploiting the PCR-RFLP technique. A literature search was completed to investigate the involvement of this variant with obesity from various genetic databases. In this case-control study, the distribution of UCP2 (rs659366) variant showed a significant association with obesity among Egyptian subjects under allelic and dominant models (P value = 0.0006 and less then 0.001, respectively). Overall, twenty-five comparisons for this variant (8652 obese patients and 10,075 non-obese controls) were recruited in this meta-analysis survey. A noteworthy association of UCP2 (rs659366) variant with obesity was identified among Asians and Africans but not Caucasians under allelic, dominant as well as heterozygote models. Nevertheless, this meta-analysis could not accomplish a noticeable association with overall subjects under different genetic models. This case-controlled study revealed a robust association for UCP2 (rs659366) variant with obesity susceptibility in Egyptian subjects; however, this meta-analysis survey failed to achieve an association for this variant with obesity in overall subjects except among Asians and Africans.Purpose The role and uptake of internal mammary nodal irradiation (IMNI) is variable. This study was designed to quantify the rates and determinants of IMNI at a tertiary cancer center. Methods Consecutively treated breast cancer patients receiving adjuvant locoregional radiation therapy (RT) from January 1, 2012 to December 31, 2017 were sorted by IMNI receipt, disease risk and time period of RT delivery (2012-2015 vs 2016-2017). Differences between risk categories and groups were evaluated using χ2/Fisher's and Mann-Whitney test for categorical and continuous variables, respectively. Univariable and multivariable logistic regression analysis was done to determine factors associated with IMNI receipt. Results A total of 1566 patients were eligible, with 376 in Group 1 (IMNI), and 1190 in Group 2 (no IMNI). The proportion of patients receiving IMNI increased significantly each year (p less then 0.0001), and 83% of patients receiving IMNI had pT1-2/pN1 disease. On univariable analysis, younger age, lymphovascular invasion, medial/central quadrant, higher stage, PR negative, mastectomy, axillary dissection, receipt of chemotherapy and nodal positivity had higher odds of IMNI. On multivariable analysis, younger age (p = less then 0.001), medial/central quadrant (p = 0.0026), PR negative (p = 0.0011), mastectomy (p = 0.0055), increasing nodal positivity (p less then 0.0001) and late cohort (p = 0.001) had increased likelihood of IMNI. The use of deep-inspiration breath hold was significantly higher in those receiving IMNI (45% vs 26%, p less then 0.0001), and permitted achievement of acceptable mean heart and lung doses. Conclusions There was a significant increase in IMNI utilization after 2015. Younger age, medial/central quadrant, PR-negative and node-positive disease predicted for receipt of IMNI. Modern RT techniques permit the safe delivery of IMNI.Background Skeletal-related events (SREs) are significant contributors to the morbidity and mortality in patients with bone metastasis from breast cancer. Thus, bone-modifying agents (BMAs) are recommended in this population. However, the baseline risk factors of SREs in patients with bone metastasis from breast cancer receiving BMAs are not well understood. read more Methods We analyzed the patient-level data from a controlled arm of a clinical trial comparing denosumab with zoledronate in patients with bone metastases from breast cancer (ClinicalTrial.gov ID NCT00321464) available at Project Data Sphere, a broad-access research platform that collects and curates patient-level data from completed, phase III cancer trials. The primary endpoint was the first SRE after the inclusion to the trial. The time to the first on study SRE was analyzed using Cox proportional hazards model based on patients' baseline characteristics including age, race, ECOG performance status (PS), histology and immunohistochemistry of breast cancer, and urine and serum laboratory data. Results Among 756 patients in the zoledronate arm of the trial, we excluded 64 patients with a documented history of osteopenia or osteoporosis. The median age of the patients was 56 years old, the median follow-up was 553 days, and 249 patients (36%) had SREs. The univariate analysis showed that black or African American heritage, ECOG PS > 0, human epidermal growth factor receptor 2 (HER2) positivity, high urine N-telopeptide cross-links / creatinine ratio (NTx/Cre), and elevated serum alkaline phosphatase (ALP) are significant baseline risk factors for SREs. Patients with the characteristics of ECOG PS > 0, HER2 positivity, and elevated ALP also showed a significantly higher hazard ratio of SREs in multivariate analysis. Conclusions We determined risk factors for SREs in patients with bone metastasis from breast cancer.
