the toxicity of 7 herbicides to the three cyanobacteria was tested in this work. the results indicated that: (1) there was a highly significant relationship between dried weight or chlorophyll-a and od680nm for tested cyanobacteria; (2) the toxicity of the tested herbicides with the order from high to low was: photosynthesis-inhibiting > accase inhibitor > protox inhibiting herbicides; (3) the ...

The growth-inhibiting action of serum has been shown to be due largely to the lipoids. Serum from which the lipoids have been removed is much less inhibiting to the growth of fibroblasts in vitro than is the original serum, and only slightly more inhibiting than Tyrode solution. The lipoids extracted from the serum are toxic and more inhibiting to the growth of fibroblasts than the original ser...

The increased inhibiting action of serum with age on the growth of fibroblasts has been shown to be due to changes in both the lipoids and the proteins. Although the serum protein is less inhibiting than the serum lipoid, the rate at which their inhibiting action augments with age is approximately the same. The change in the serum protein with age is due to the disappearance of a small quantity...

autism spectrum disorder (asd) is a mental condition, present from early childhood, characterized by great difficulty in communicating and forming relationships with others and using language. in the last four decades many studies have shown that immune responses in different regions of brain play an important role in asd pathogenicity. a conservative estimate based on the research suggests tha...

The market value of crustaceans depreciates during storage due to the appearance melanosis caused by polyphenol oxidases. Sulfite derivatives are used as melanosis-inhibiting agents, but their unhealthy effects make it preferable replace them with natural preservatives. In this work, a crude enzymatic extract from whiteleg shrimp (Penaeus vannamei) was characterized and test diphenol oxidase-in...

In this paper the researchers tried to study the status of tourism and rural tourism economy in Iran the condition of entry and exit of tourists in Iran, as well as the inhibiting factors affecting their positive impacts on Iran economic status. To achieve this objective, the researchers used documentary research methods. In addition, the researchers used a field research method based on the da...

Abstract Owing to the lack of effective POST herbicide options, producers typically rely on nicosulfuron as main grass in sweet corn production systems. In 2019, a Wisconsin producer reported fall panicum control escapes after spraying nicosulfuron. Seeds from mature plants were collected (1) measure response acetolactate synthase (ALS)-inhibiting herbicides, (2) elucidate resistance mechanism,...
