Potential of Different Polyamino Carboxylic Acids as Barium and Strontium Sulfate Dissolvers

Abstract The studies were focused on testing various scale dissolvers for barite sag or barium sulfate scales, although the chemically similar substance, strontium sulfate, attracted less attention. To compare the behavior of these two compounds, an extensive research program was launched with the aim of evaluating the stability of seven distinct polyamino carboxylic acids using both scientific and economic perspectives. In both the presence and absence of reservoir rock, the dissolving capacity of each compound was determined under equilibrium conditions as a function of BaSO4 and SrSO4 concentrations. The sequence of dissolution capacity is different if the results were assessed in either a scientific or economic sense, according to the experimental findings. The results of that systematic review may lead to new horizons in mitigation of formation damage caused by BaSO4 or SrSO4 formation damage, as well as the searching for more precise mixtures of complex-forming dissolvers.

Effect of 1-aminocyclopropane-1-carboxylic acid accumulation on Verticillium dahliae infection of upland cotton

Abstract Background Verticillium wilt of cotton is a serious disease caused by soil-borne fungus Verticillium dahliae Kleb infection, and infection mechanisms may necessitate the control of phytohormone ethylene. We investigated how ACS activation and ACC accumulation may have affected V. dahliae strain Vd991's infection of cotton cultivar YZ1. Conclusions Preliminary observations showed that ACC applications reduced the disease prevalence, disease index, and stem vascular browning by inhibiting fungal biomass accumulation. These ACC-grown plants in a Verticillium disease nursery with about 50 microsclerotia per gram of soil showed reduced disease counts, stem fungal biomasses, and vascular browning. These transgenic plants reduced the green fluorescent protein-marked Vd991 colonization and diffusion in root tissue, making them more useful. Conclusions The GhACS2 - and GhACS6-dependent ACC accumulations extended the cotton resistance to V. dahliae in a SA-dependent manner, and this provides the foundation for cotton resistance breeding.

The 1-aminocyclopropane-1-carboxylic acid deaminase-producing Streptomyces violaceoruber UAE1 can provide protection from sudden decline syndrome on date palm

The sudden decline syndrome in the United Arab Emirates is one of the most common fungal diseases caused by Fusarium solani affecting date palm plantations. Native actinobacterial strains isolated from healthy date palm plants' rhizosphere soils were identified against F. solani DSM 106836 to minimize the effect of the causal agent of SDS on date palm plants. This was evident from the signs of SDS in diseased date palm seedlings, which were markedly reduced by Sv in comparison to St. The number of conidia of Fs recovered from plants that were pre-treated with both BCAs was approximately similar, but significantly reduced compared to plants without any BCA treatment. However, in planta ACC levels, the seedlings growing in soils heavily contaminated with the pathogen alone or mixed with St prior to F. solani infestation are at an all-time peak.

Evaluation of 4-methyl-2-[(2-methylbenzyl) amino]-1,3-thiazole-5-carboxylic acid against hyperglycemia, insulin sensitivity, and oxidative stress-induced inflammatory responses and β -cell damage in the pancreas of streptozotocin-induced diabetic rats

In streptozotocin-induced neonatal models of non-insulin-dependent diabetes mellitus rats where NIDDM was introduced in neonatal pups with single intraperitoneal injection of STZ, effects of BAC on hyperglycemia, insulin sensitivity, oxidative stress, and inflammation were tested, including inflammatory mediators. The results of BAC for three weeks was evaluated by the determination of blood glucose, oral glucose tolerance test, HbA1c level, insulin sensitivity, and insulin resistance. The potential of BAC in STZ-induced neonatal models of NIDDM rats indicated a significant decline in blood glucose, OGTT, HbA1c, insulin level, insulin sensitivity, in addition to variations in the antioxidant status and inflammatory mediators, as well as changes in histoarchitecture of pancreatic tissue. The IR decreased the level of glucose and raised the insulin sensitivity, which was treated with BAC. After BAC administration to diabetic rats, histological investigations of pancreatic tissues revealed normal architecture.

Enzymatic Strategies for the Preparation of Pharmaceutically Important Amino Acids through Hydrolysis of Amino Carboxylic Esters and Lactams.

Abstract: The most recent lipase-catalyzed plans for the manufacture of pharmaceutically critical cyclic and acyclic enantiomers are overviewed, with hydrolysis of the corresponding amino carboxylic esters and lactams over the last decade. In the Main Text, the enantiomeric amino acids' pharmacological importance is given next to their synthesis, and it is also illustrated in the Conclusions and Outlook sections.

β-Cell-protective effect of 2-aminobicyclo-(2,2,1)-heptane-2-carboxylic acid as a glutamate dehydrogenase activator in db/db mice

We investigated the effect of BCH on the glucose-stimulated insulin secretion reduction, the HG/palmitate -induced decrease in insulin gene expression, and HG/PA-induced u03b2-cell death. In db/db mice, we also tested whether long-term BCH therapy raises blood glucose levels and improves u03b2-cell stability. In the presence or absence of BCH, we investigated GSIS, insulin gene expression, and DNA fragmentation in INS-1 cells exposed to HG or HG/PA. An in vivo experiment was conducted in a 7-week-old diabetic db/db mice were treated with BCH and placebo every other day for six weeks. BCH-induced GSIS inhibition and the HG/PA-induced decrease in insulin gene expression in INS-1 cells were stifled by treatment with BCH. BCH therapy also raised the number of insulin-positive u03b2-cells to total islet area, and reduced the number of u03b2-cells expressing cleaved caspase 3 in a total islet area. In conclusion, the GDH activator BCH improved glycemic regulation in db/db mice.
