RESULTS The performance of the normal flow LC-MS/MS assay was evaluated by using it to quantify FGF-21 protein, a potential biomarker for non-alcoholic fatty liver disease, in serum samples. Multiple replicated PRM sample quantification results demonstrated the excellent reproducibility and operational robustness of the assay. A limit of quantification of less than 0.4 ng/mL for FGF-21 in a complex serum matrix could be achieved by using the heavy-isotope-labeled peptide technique, a result which is comparable with the nano-LC/SRM MS based assay sensitivity. CONCLUSIONS The strategy offered an effective alternative to nano-LC/SRM MS for the quantification of protein biomarkers in complex biomatrix with much improved reproducibility and operational robustness.

UECs were isolated from slaughterhouse derived uteri by enzymatic treatment and cells were characterized by immunocytochemistry (ICC) and PCR assays. The well characterized UECs were exposed to different concentrations of P4 (0, 0.314. 3.14 and 6.28 ng/ml) along with the basal level of estradiol for 6 days. Thereafter, the relative mRNA expression of different biomolecules; mucin 1(MUC1), osteopontin, integrin alpha (α3, α6 and αV) and beta (β1 and β3) subunits, progesterone receptor (PR) and estrogen receptor was evaluated. Further, day 2 post insemination embryos were cultured in mSOF supplemented with or without P4. UECs were found positive for cytokeratin expression and negative for vimentin expression. Progesterone treatment significantly enhanced mRNA expression of most of the transcripts compared to the control group and correspondingly the immunofluorescence depicted higher protein expression of all these molecules. Further, long term exposure of UECs to P4 down regulated the expression of PR and concomitantly MUC1. Progesterone supplementation to embryo culture medium significantly (P less then 0.05) improved the blastocysts rate. The study demonstrates the role of P4 hormone in modulation of expression of early implantation related biomolecules in uterine epithelial cells; hence adequate level of steroids is crucial for normal embryo development and its implantation.

Thirty-six pluriparous ewes received progestogen sponge (60 mg) for nine days plus eCG administration (300 IU i.m.) 24 h before sponge removal. Ewes were not mated and were randomly assigned to receive at 16 h before NSER 37.5 µg d-cloprostenol i.m. and different doses of estradiol benzoate 0.0 mg (0EB group; n=12); 0.5 mg (0.5EB group; n=12) or 1.0 mg of estradiol (1.0EB group, n=12). All ewes received oxytocin (50 IU) i.v. 20 min before NSER, which was performed eight days after sponge removal. Corpora lutea were counted by transrectal ultrasonography 24 h before NSER. After procedure, the ewes were kept in natural breeding period to check their post-NSER fertility. NSER was performed in 91.7% (33/36) of the animals with overall fluid recovery efficiency over 97% (P>0.05). The cervical transposing with Hegar dilator was longer (P0.05). The post-NSER fertility was higher (P less then 0.05) in 0.0EB (90%) than 0.5EB group (36.4%). In conclusion, NSER can be successfully performed in Dorper ewes by using a cervical relaxation protocol without estradiol benzoate. This article is protected by copyright.

The evolution of the secondary structure from random coils to the β-sheets was determined by using FTIR, Circular Dichroism (CD) and XRD. The results showed that Muga silk fibroin protein contained the primary structure in silk-I state. When the protein was irradiated with microwave, nanoparticle synthesis was possible having silk-II state imparting crystallinity. The silk nanoparticles were characterized by a particle size analyzer (PSA) and found to be of 240 nm in size. The optical properties of these nanoparticles were studied by UV-Vis. buy 1400W spectroscopy and photoluminescence (PL). For studying thermal properties DSC was performed that revealed early glass transition, which could be attributed to the presence of water and proteins. It also revealed that nanoparticles are thermally stable. Such studies are important for understanding more about the Muga silk nanoparticles and would be beneficial for their further wide applications. This article is protected by copyright.

Tobacco and alcohol expenditure may also exacerbate poverty. This study aimed to estimate the financial impact of tobacco and alcohol consumption in low income households in the UK. DESIGN Cross-sectional study. SETTING UK. PARTICIPANTS A sample of 5,031 households participating in the 2016-17 Living Costs and Food Survey. MEASUREMENTS Weekly household income and expenditure on tobacco and alcohol; proportion of households with expenditure on tobacco and alcohol overall, by income decile and in households in relative poverty (below 60% of the median household income). Estimates were extrapolated using population data to estimate the number of UK households, adults and children that would be classified as living in relative poverty on the basis of net income after subtracting tobacco or alcohol expenditure ('tobacco and alcohol expenditure-adjusted poverty'). FINDINGS Spending on alcohol was more common in high income groups; 83% of households in the highest and 47% in the lowest income decile purchased alcohol. The reverse was true for tobacco, which was purchased by 8% and 24% of households in the highest and lowest income deciles respectively. Twenty-three percent of households in relative poverty purchased tobacco and 49% alcohol, with a median expenditure of £12.50 and £9.55 per week respectively. A total of 320,000 households comprising 590,000 adults and 175,000 children were in alcohol expenditure-adjusted poverty, and 230,000 households, comprising 400,000 adults and 180,000 children in tobacco-expenditure adjusted poverty. CONCLUSIONS Tobacco and alcohol expenditure appear to exacerbate poverty in low income households in the UK. Hundreds of thousands of additional households would be defined as living in relative poverty based on their income after subtracting their tobacco and alcohol expenditure.
