Previous research indicated that resistance to stigmatellin in yeast with the F129L mutation could be due to a subtle alteration of the backbone fold at Qo that reduced the antagonist’s access to the Qo site, but that limited cross-resistance to azoxystrobin and sensitivity to pyraclostrobin was likely due to the difference in pharmacophore structure between these two compounds31. Our models on the effect of F128S mutation on the binding of fungicides to Qo indicated that the mutation reduced hydrophobic interactions and other interactions and that the effects of the F128S mutation differed for the five QoI fungicides. π-π stacking almost disappeared for SYP-1620 and enestroburin, remained for azoxystrobin and ZJ0712, and was reduced for SYP-2815. This is consistent with the bioassay results, which indicated that the F128S mutation resulted in high resistance to SYP-1620 and enestroburin and low or intermediate resistance to the other three fungicides. We also provided insight into how the Y131C mutation could alter the Qo-binding pocket and therefore result in high resistance to QoI fungicides, although this mutation was generated by exposure to UV irradiation.

OUTLOOK ’17: US TDI rise on supply, MDI stay steady US prices for isocyanates are mixed heading into the new year, with prices for toluene di-isocyanate (TDI) shooting up on global supply tightness while prices for methyl di-p-phenylene isocyanate (MDI) are following a mostly steady trend. In the TDI market, tight supplies have resulted in significant upward movement in major global markets.

One to 3 weeks after xenograft initiation, all animals were anesthetized with 1 to 3% isoflurane, the neck area was shaved, and the left jugular vein was isolated for placement of a PE-10 polyurethane catheter to facilitate the injection of the radiotracer. The animals were injected with 80 μCi of 64Cu-NOTA-PEG4-cRGD2 targeted to αvβ3 (a well-characterized marker of angiogenesis). Imaging was performed using a hybrid small-animal microPET-CT scanner (Inveon, Siemens Healthcare). The animals were placed on the animal bed, and 60 min after radiotracer injection, a 15-min microPET imaging session was performed. This was followed by a high-resolution anatomical microCT imaging (360 projections; energy, 80 keV/500 μA). The microPET and microCT images were reconstructed using OSEM (ordered subset expectation maximization)/3D algorithm (Siemens Healthcare) and cone beam technique (COBRA, Exxim), respectively.

"The availability of such a process will expand the food, pharma and polymer applications requiring a purity of more than 99 percent," the lab said.

"These research findings will support industries that want green alternatives to additives that are known to have varying levels of toxicity," Ford said. "Our team plans to use glucaric-acid, lignin and potentially other biobased additives to process plastics for safe contact with food, people and our environment."

The New York Times: Why Half A Degree Of Global Warming Is A Big Deal Half a degree may not sound like much. But as the report details, even that much warming could expose tens of millions more people worldwide to life-threatening heat waves, water shortages and coastal flooding. Half a degree may mean the difference between a world with coral reefs and Arctic summer sea ice and a world without them. (Plumer and Popovich, 10/7)

Sales & Marketing trading for Winter 2018/19 (which is low season for most markets) is at a relatively early stage, with around one third of the programme sold. Performance is positive overall, with customer volumes up 2%. Bookings in most markets are ahead of prior year and tracking in line with capacity. In Nordics, we are seeing a later booking profile this Winter, in line with the market, against strong prior year comparatives and as a knock-on impact from the prolonged hot Summer in Scandinavia. Average selling price overall for Sales & Marketing is down 1% on prior year. This reflects a proactive remix of capacity, enabling us to capitalise on the returning popularity of North Africa and Turkey, and also to reduce our capacity to the Canaries where demand is normalising.

Global and China Acrylic Acid & Esters Industry Report, 2012-2015 of ReserachInChina, mainly covers the followings:

Inverse polymerase chain reaction (IPCR) and 3′ rapid amplification of cDNA ends (3′ RACE) were used to amplify the flanking fragment of cytb in P. litchii. IPCR was performed according to the procedure previously reported35, with slight modifications. Briefly, 2 μl (300 ng/μl) of gDNA of P. litchii (wild-type isolate 38) was digested with 1 μl of EcoR I (Thermo Scitific, Shanghai, China) in a total volume of 20 μl at 37 °C for overnight; the enzyme activity was inactivated by heating at 65 °C for 20 min. Circularization was conducted in a total reaction volume of 200 μl containing 4 μl of digesting DNA products, 5 μl of T4 ligase (TransGen Biotech, Beijing, China), 20 μl of 10× T4 DNA ligase buffer (TransGen Biotech, Beijing, China), and 171 μl of ddH2O. After incubation at 25 °C for 10 min, the circularized DNA was purified with the CTAB procedure34. The circularized DNA was amplified using gene-specific primers (GSP, Table 3) designed according to the partial cyt b gene sequence and targeted toward the flanking sequences. All primers were synthesized by Beijing Sunbiotech Co. Ltd. (Beijing, China). The first round of IPCR amplifications was performed in a total reaction volume of 50 μl containing 5 μl of 10× Taq reaction buffer (2.5 μM, TransGen Biotech, Beijing, China), 2 μl of dNTP (10 mM each, TransGen Biotech, Beijing, China), 2.5 μM of each primer (10 μM, GSP1 and GSP5), 5 ng of circularized DNA template, 32 μl of H2O, and 5 U of Taq DNA polymerase (TransGen Biotech, Beijing, China). Cycling parameters were 94 °C for 5 min; followed by 35 cycles of 94 °C for 30 s, 62 °C for 30 s, and 72 °C for 3 min; and a final extension of 10 min at 72 °C. The first IPCR products, diluted 10-fold and 100-fold, were used as template for the second round of IPCR. The same reaction system was used as for the first amplification except that the primers were replaced with two pairs of nested primers: GSP2/GSP5 and GSP7/GSP8. Cycling parameters were as described for the first round except that both 60 °C and 64 °C were used as the annealing temperature.

“We feel that is the right time to make this important change, as the Company evolves from a start-up to a fast-scaling commercial enterprise. I am proud of the success Maestrano has achieved to date and I am very confident that Andrew will deliver on our potential, for the benefit of all stakeholders.”
