Serum samples taken for fasting & PP C-peptide and HbA1C for patients of T2 Diabetes Mellitus and run on VITROS 5600/7600 which is based on dry chemistry. : We took 50 patients who were T2DM then we did fasting C peptide & PP C-peptide and HbA1c. Out of 50, 15 were females &35 were males. Out of 50, 45 patients had raised HbA1C maximum around 8-10.Mean & SD for fasting C-Peptide for males was 1.346±1.070 & for females 2.442±2.57.Mean & SD for Post prandiol C-Peptide for males was 4.208±5.020 & for females 2.993±2.130.It was significant for fasting C- Peptide with P value 0.0371 and non significant for PP C peptide with p value 0.3731.: Insulin secretion estimated by measurement of Fasting C-Peptide was either normal or raised in newly diagnosed T2DM subjects in my study in...

Serum samples taken for Hs Troponin I and Uric Acid for patients of Myocardial Infarction and run on VITROS 5600/7600 which is based on dry chemistry. : With 100 patients of more than 40 years of age 61 were males & 39 were females. For both males & females age mean & SD was 59.8±10.77.In our study we took 100 random patients coming to cardiac emergency out of which 50 patients had raised trop I and 45 patients had raised uric acid levels. Out of those 50 patients with raised HS Trop I 25 patients had raised values for uric acid. For Hs Trop I males – 21.88±48.8 & females 1676±57.58. For uric acid for males-6.545±3.75 & for females- 6.315±1.86.Therefore Hs Trop I & uric acid were both significant when compared with age T value was 2.7001 and P value was 0.0075. Whereas when compared with sex that is male and f...
优质米业对云南地方经济的持续发展和边疆民族的脱贫具有重要作用。‘滇屯 502 ’是云南优质香软米生产的主要品种，也是香软米品种改良的主要香稻资源，但对于‘滇屯 502 ’香味性状的遗传规律迄今尚... more 优质米业对云南地方经济的持续发展和边疆民族的脱贫具有重要作用。‘滇屯 502 ’是云南优质香软米生产的主要品种，也是香软米品种改良的主要香稻资源，但对于‘滇屯 502 ’香味性状的遗传规律迄今尚不清楚。本研究利用水稻香味基因 badh2 特异引物，结合米粒咀嚼法，分析了‘滇屯 502 ’香味性状的遗传规律，及其杂交后代的表型差异。结果表明‘滇屯 502 ’的香味性状受核隐性基因 badh2 控制，其遗传分离比例不受细胞质基因背景和种植环境差异的影响。对 F 2 单株和 F 3 株系分析，虽未发现与香味性状明显相关的农艺性状，但具香味性状的单株穗实粒数、穗总粒数、有效穗和结实率均低于无香味性状的，尤其是 F 3 香味株系更明显地表现出穗实粒数少、结实率低、产量低的特性。本研究结果为开展‘滇屯 502 ’品种改良和提纯复壮提供理论依据。

This cost is expected to further increase after the new “Lead-Free” requirements of the Safe Drinking Water Act (SDWA) are implemented on January 4, 2014. How much more would lead-free products cost? What are the new requirements? How can we prepare for it? These are the questions being discussed in the drinking water industry. In the next few months, all involving parties including EPA, manufacturers, and constructors will be working together to address these issues.

Qureshi has combed the records in London, Karachi, and Istanbul to highlight the pan-Islamic aspects of the movement, whereas my thesis emphasizes its nationalist dimensions. Qureshi views the emergence of this mass movement among Indian Muslims as an outcome of their sympathy for their fellow Muslims in the central Islamic lands and their loyalty to the Ottoman sultan as the caliph of Islam. This happened during a period when the Ottoman Empire, defeated in World War I, was threatened with dismemberment by the victorious European powers. Muslims in India pleaded for the retention of the Ottoman sultan-caliph's temporal as well as spiritual powers, and when their pleas went unheard at the Versailles peace conference, they turned against their British rulers ...

Harzianols AÀE (2e6) and harziane acid (7), six new oxidized derivatives of harzianone (1), were ... more Harzianols AÀE (2e6) and harziane acid (7), six new oxidized derivatives of harzianone (1), were obtained from the microbial transformation by a bacterial strain Bacillus sp. IMM-006. The structures of these products, including the stereochemistry, were elucidated by extensive spectroscopic analysis. The absolute configuration of 2 was unambiguously determined by single-crystal X-ray diffraction. Moreover, a plausible bioconversion pathway was proposed.

The standard of 5 pCi/L for combined radium (Ra) 226 and 228 will affect more than 500 US systems and 1.4 million people in 177 cities in the Midwest. The best available technology for Ra removal includes ion exchange, lime softening, and reverse osmosis. However, hydrous manganese oxide and manganese greensand filtration is capable of removing up to 80% of Ra. For plants designed to remove iron and manganese by a manganese greensand filtration system, the cost of removing Ra is minimal. Results of pilot-and full-scale studies are reported from Bellevue Sanitary District 1 in Brown County, Wis.

It is generally believed that mixed media, which contain anthracite coal, sand, and high-density sand, is closer to an ideal filter than dual media, which contain only coal and sand. However, comparative pilot-and plant-scale studies conducted under identical pretreatment conditions at Minneapolis and at other locations indicate very little difference in performance between the two types of filters.

At high pH, when the predominant mode of alum coagulation is sweep coagulation, increasing the intensity of chemical mixing reduced aluminum residuals only slightly. Reducing the pH with acid was effective in reducing the residuals, but posttreatment pH adjustment with lime to stabilize the water increased its hardness. It appears that the most promising means of reducing aluminum residuals is to replace part of the alum dosage with ferric chloride. At both Minneapolis and St. Paul water treatment plants, ferric chloride, at less than half the dosage of alum, reduced the residuals and resulted in longer filter runs.

In this study, structurally diverse prenylflavonoids were conveniently synthesized by enzymatic catalysis by combining GuILDT, a regiospecific chalcone prenyltransferase, and GuCHI, a stereospecific chalcone isomerase that has promiscuous activity for both chalcones and prenylchalcones as substrates. Our findings provided a new approach for the synthesis of natural/unnatural bioactive prenylflavonoids, including prenylchalcones and optical prenylflavanones with chalcone origins.

These bioactive flavonol glycosides usually have a rhamnose moiety at the 3-OH position of prenylflavonols, such as icariin (9), baohuoside I (1a) and baohuoside II (2a). However, to date, no rhamnosyltransferase has been reported to catalyze the 3-O-rhamnosylation of prenylflavonols. In this article, a flavonol rhamnosyltransferase, EpPF3RT, was identified from E. pseudowushanense B. L. Guo. The recombinant enzyme regiospecifically transfers a rhamnose moiety to 8-prenylkaempferol (1) and anhydroicaritin (2) at the 3-OH position to form baohuoside II (1a) and baohuoside I (2a) in vitro. In addition, a UDP-rhamnose synthase gene, EpRhS, from E. pseudowushanense was functionally characterized and used to produce the UDP-rhamnose sugar donor. Furthermore, an engineered Escherichia coli strain containing EpPF3RT and EpRhS was established to produce baohuoside ...
