It is the most widely used herbicide in the world, and the third most commonly used in North America.[1] 2,4-D is also an important synthetic auxin, often used in laboratories for plant research and as a supplement in plant cell culture media such as MS medium. History 2,4-D was developed during World War II by a British team at Rothamsted Experimental Station, under the leadership of Judah Hirsch Quastel, aiming to increase crop yields for a nation at war.[citation needed] When it was commercially released in 1946, it became the first successful selective herbicide and allowed for greatly enhanced weed control in wheat, maize (corn), rice, and similar cereal grass crop, because it only kills dicots, leaving behind monocots. Mechanism of herbicide action 2,4-D is a synthetic auxin, which is a class of plant growth regulators. -

Hemangiosarcoma Philip J
Ettinger & Feldman – Textbook of Veterinary Internal Medicine Client Information Sheet Hemangiosarcoma Philip J. Bergman What is hemangiosarcoma? Hemangiosarcoma (HSA; angiosarcoma or malignant hemangioendothelioma) is an extremely aggressive tumor of blood vessel origin. Because blood vessels are present throughout the body, virtually any site in the body can have HSA. HSA occurs most frequently in dogs (approximately 2% of all tumors) and the most common site is the spleen. However, additional common sites include the heart, liver, muscle, lung skin, bones, kidney, brain, abdomen, and oral cavity. In three large canine splenic disease studies encompassing approximately 2000 dogs, a “rule of two thirds” was found suggesting that approximately two thirds of dogs with a splenic mass have a cancer (therefore one third are not malignant) and two thirds of the malignant tumors of the spleen are HSA. HSA is a disease generally of older dogs and cats with an average onset of 9 to 10 years; however, there are reports of extremely young dogs and cats with this disease (5 to 6 months to a few years of age). German shepherd dogs are most commonly diagnosed with HSA; however, other large breed dogs such as golden retrievers and Labrador retrievers may also be overrepresented. In cats, the most common breed is the domestic shorthair. The cause of HSA in dogs and cats is presently unknown. Exposures to toxins such as chemicals, insecticides, and radiation have been reported in humans to be associated with HSA. Ultraviolet light exposure from the sun may be a potential cause of HSA in dogs, as HSAs of the skin are commonly seen in dogs with light hair and poor pigmentation (e.g., Salukis, Whippets, and white Bulldogs). -
Greenhouse and Field Evaluation of Isoxaflutole for Weed Control In
www.nature.com/scientificreports OPEN Greenhouse and field evaluation of isoxaflutole for weed control in maize in China Received: 27 June 2017 Ning Zhao, Lan Zuo, Wei Li, Wenlei Guo, Weitang Liu & Jinxin Wang Accepted: 18 September 2017 Greenhouse and field studies were conducted to provide a reference for pre-emergence (PRE) Published: xx xx xxxx application of isoxaflutole on maize in China. In greenhouse study, the isoxaflutole PRE application at 30 g active ingredient (a.i.) ha−1 could effectively control large numbers of weeds, especially some large-seeded broadleaves, tested in this study. The tolerance results indicated 21 maize hybrids showed different responses to isoxaflutole under greenhouse conditions. In 2015 and 2016, field experiments were conducted to determine and compare the weed control efficacy and safety to Zhengdan 958 maize with 6 herbicide treatments. In both years, isoxaflutole PRE at 100 to 250 g a.i. ha−1 was sufficient to provide satisfactory full-season control of the dominant common broadleaf and grass weeds in the field. Temporary injury to maize was observed with isoxaflutole treatments of 125, 150, and 250 g a.i. ha−1 in both years, but plants recovered within 4 to 6 wk. To maximize maize yield and provide satisfactory weed control, a range of 100 to 150 g a.i. ha−1 of isoxaflutole is recommended, depending on the soil characteristics, weather, and weed species present at the experimental site. Based on the results, isoxaflutole PRE has good potential for weed control in maize in China. Maize was planted on more hectares than any other crops in China from 2010 to 2014, with an average of 35 million ha planted per year and yield averaging 5,779 kg per ha per year1. -
Exposure to Herbicides in House Dust and Risk of Childhood Acute Lymphoblastic Leukemia
Journal of Exposure Science and Environmental Epidemiology (2013) 23, 363–370 & 2013 Nature America, Inc. All rights reserved 1559-0631/13 www.nature.com/jes ORIGINAL ARTICLE Exposure to herbicides in house dust and risk of childhood acute lymphoblastic leukemia Catherine Metayer1, Joanne S. Colt2, Patricia A. Buffler1, Helen D. Reed3, Steve Selvin1, Vonda Crouse4 and Mary H. Ward2 We examine the association between exposure to herbicides and childhood acute lymphoblastic leukemia (ALL). Dust samples were collected from homes of 269 ALL cases and 333 healthy controls (o8 years of age at diagnosis/reference date and residing in same home since diagnosis/reference date) in California, using a high-volume surface sampler or household vacuum bags. Amounts of agricultural or professional herbicides (alachlor, metolachlor, bromoxynil, bromoxynil octanoate, pebulate, butylate, prometryn, simazine, ethalfluralin, and pendimethalin) and residential herbicides (cyanazine, trifluralin, 2-methyl-4- chlorophenoxyacetic acid (MCPA), mecoprop, 2,4-dichlorophenoxyacetic acid (2,4-D), chlorthal, and dicamba) were measured. Odds ratios (OR) and 95% confidence intervals (CI) were estimated by logistic regression. Models included the herbicide of interest, age, sex, race/ethnicity, household income, year and season of dust sampling, neighborhood type, and residence type. The risk of childhood ALL was associated with dust levels of chlorthal; compared to homes with no detections, ORs for the first, second, and third tertiles were 1.49 (95% CI: 0.82–2.72), 1.49 (95% CI: 0.83–2.67), and 1.57 (95% CI: 0.90–2.73), respectively (P-value for linear trend ¼ 0.05). The magnitude of this association appeared to be higher in the presence of alachlor. -

It shows a particular predi- lection for the skin and superficial soft tissues. We report three distinct and typical cases of angiosarcoma that were diagnosed in a single dermatology clinic over the course of less than a year: i) Angiosarcoma in lower limb affected by chronic lymph- edema, featuring Stewart-Treves syndrome; ii) a case of the most common type of angiosarcoma loated in the scalp and face of elderly man and; iii) a skin Angiosarcoma in previously irradiated breast. All lesions presented characteristic histopathological findings: irregular vascular proliferation that dissects the collagen bundles with atypical endothelial nuclei projection toward the lumen.

Secondary Electrospray Ionization Proceeds Via Gas-Phase Chemical Ionization Cite This: Anal

Methods,2017,9,5052 Alberto Tejero Rioseras, abc Martin Thomas Gaugga and Pablo Martinez-Lozano Sinues *ad Our main goal was to gain further insights into the mechanism by which gas-phase analytes are ionized by interaction with plumes of electrospray solvents. We exposed target vapors to electrosprays of either water or deuterated water and mass analyzed them. Regardless of the solvent used, the analytes were detected in Received 30th April 2017 protonated form. In contrast, when the ionization chamber was humidified with deuterated water, the target Accepted 20th June 2017 vapors were detected in deuterated form. These observations suggest that either there is no interaction DOI: 10.1039/c7ay01121k between analytes and electrospray charged droplets, or if there is any, a subsequent gas-phase ion– rsc.li/methods molecule reaction governs the process.
