Objective:To determine the influence of the single nucleotide polymorphism(SNP)rs4245739 on the binding and expression of micro RNAs and subsequent MDM4 expression and the correlation of these factors with clinical determinants of ER-negative breast ***:Find Tar and miRanda were used to detect the manner in which potential micro RNAs are affected by the SNP rs4245739-flanking *** sequencing data for ER-negative breast cancer from The Cancer Genome Atlas(TCGA)were used to compare the expression of miR-184,miR-191,miR-193a,miR-378,and MDM4 in different rs4245739 ***:Comparison of ER-negative cancer patients with and without the expression of miR-191 as well as profile micro RNAs(miR-184,miR-191,miR-193a and miR-378 altogether)can differentiate the expression of MDM4 among different rs4245739 *** simple genotyping alone did not reveal significant clinical relationships,the combination of genotyping and micro RNA profiles was able to significantly differentiate individuals with larger tumor size and lower number of involved lymph nodes(P<0.05)in the risk group(A allele).Conclusions:We present two novel methods to analyze SNPs within 3′UTRs that use:(i)a single miRNA marker expression and(ii)an expression profile of miRNAs predicted to bind to the SNP *** demonstrate that the application of these two methods,in particular the miRNA profile approach,permits detection of new molecular and clinical features related to the rs4245739 variant in ER-negative breast cancer.

Fatty acid esters have been prepared by reacting the acid C//1//8 with polyethylene glycols having varying numbers of oxyethylene units (4-88 units) by the direct esterification reaction method. Surface and interfacial tensions were studied at various experimental conditions, including, concentration, temperature and chemical constitution of the surfactant. Critical micelle concentrations (CMC), surface excess and residual area occupied by each surface active agent molecule A have been calculated by using Gibb's equations. CMC values range from 10 to 55 multiplied by 10** minus **5 mole/L for all studied agents, while the residual area occupied by each molecule varies from 0.6 to 1.5 nm**2. Variation of CMC of some of these agents with temperature have been also examined and the obtained data were used to calculate the heat of micellization delta H//m and the entropy change during micellization delta S//m. Values of delta H//m vary from 14.63 kJ/mole to 2.717 kJ/mole depending on the chemical constitution of the agent under consideration. The apparent dipole moments mu of three surfactant were measured following the Headstrand's method. (Edited author abstract) 23 Refs.

Understanding Pakistan's greenhouse gas(GHG)emission status is critical for identifying the national targets for GHG mitigation with respect to the nationally determined contributions(NDCs).This study focuses on the development of Pakistan's GHG(C0_(2),CH_(4),and N20)inventories for agriculture,forestry and other land use(AFOLU)and waste sectors using 2006 IPCC *** study should be seen as a direct continuation of the preceding one(Part I[Available online at:https://***/10.1016/***.2020.05.002])which discusses energy and industrial processes and product use in compliance with the 2006 and 1996 IPCC *** also provides sector-specific comparative time series(1994-2017)analysis of GHG inventories,identification of key categories,and national GHG emissions trend for *** results indicate an average relative difference(on average for time series 1994-2017)of 19%and 6%in total GHG emissions(C0_(2)-eq)from AFOLU and waste sector respectively between 2006 and 1996 IPCC *** absolute difference over the entire time series for AFOLU and waste sector was in the range of 3-67 Mt C0_(2)-eq and 1-7 Mt CQ2-eq *** further reveal that the quantity of national GHG emissions by 2006 IPCC Guidelines is 10%lower on average for complete time series compared to 1996 IPCC *** average relative difference for total national emissions of C0_(2),CH_(4) and N20 is-1%,9%,and 48%*** category analysis based on 2006 IPCC Guidelines estimates identified three categories,each contributing>10%to the level assessment in the latest year 2017 and accounting for approximately half of the national GHG *** order to further improve the reliability of GHG inventories,Pakistan needs to move from 1996 to 2006 IPCC Guidelines under a higher Tier approach particularly for identified key categories.
