Pressure-reducing and injection-enhancing anti scaling agent for low-permeability water-injection well and preparation method thereof

The present disclosure provides a pressure-reducing and injection-enhancing anti-scaling agent for low-permeability water-injection wells and a preparation method thereof. The anti-scaling agent is prepared from starting materials comprising: 10 to 12 parts of non-ionic surfactant(s), 18 to 20 parts of hexasodium triethylenetetramine-N,N,N,N,N,N-hexaacetate, 5 to 8 parts of anionic surfactant(s), 6 to 8 parts of an organic phosphonic acid-carboxylic acid scale inhibitor, 2 to 5 parts of a dispersant, 15 to 18 parts of a diluent, 8 to 10 parts of an organic amine salt, and 30 to 36 parts of water. The pressure-reducing and injection-enhancing agent according to the present disclosure is characterized by having multiple functions in one agent. When used in an amount being 0.5% of the water injected to a water injection well, it shows excellent anti-swelling property, shrinking property, anti-corrosive property, and calcium sulfate and barium (strontium) sulfate scale resistance.

Treatment of Endometriosis and Niclosamide Derivatives

Niclosamide is an effective therapeutic medicament for the treatment of endometriosis. Niclosamide treatment can reduce the size of endometriotic lesions and reduce cell proliferation in the lesions. Niclosamide treatment can result in the inhibition of proteins and genes associated with inflammatory signaling, including those associated with NFB and STAT3 activation, but without altering the expression of steroid hormone receptors. Niclosamide can be effective in reducing the growth of endometriotic lesions in female mice without impairing their ability to become pregnant and without negative effect on gestation and offspring. The invention herein is useful in treating symptoms associated with endometriosis, such as reducing the growth of lesions of the endometrium, without disrupting normal reproductive function in females. The invention also relates to derivatives of niclosamide having improved solubility and enhanced efficacy.

Drug target for treating veterinary infections and methods of using same

The invention includes a method of treating or preventing a Staphylococcus infection in a mammal or avian species in need thereof. The methods comprise administering to the mammal or avian species a therapeutically effective amount of fosmidomycin. In certain embodiments, the methods treat or prevent a drug-resistant Staphylococccus infection.

Method of making phosphono-phosphate containing compounds

A method of making a phosphono-phosphate compound is disclosed. The method involves a first step of mixing a first component comprising a phosphonic acid, a phosphonate or mixtures thereof, with a second component comprising a source of phosphoric acid or phosphate. The mixture has a molar phosphorous ratio of the first component to the second component of from 1:1 to 1:10. The second step involves either physically or chemically dehydrating the mixture to produce a phosphono-phosphate compound.
