We propose an approach for the simultaneous determination of multiple components in pharmaceutical mixed powder based on X-ray diffraction (PXRD) method coupled with chemometrics. Caffeine anhydrate, acetaminophen and lactose monohydrate were at various ratios. The samples analyzed by PXRD ranges 2θ=5.00-30.0 35.0-45.0 degrees. Obtained diffractograms conventional peak intensity method, multi curve resolution (MCR)-alternating least squares (ALS) partial (PLS) method. Constructed PLS models...

Quantitative determination of estradiol benzoate, progesterone, methyltestosterone, and ethisterone (in solution) ethynylestradiol KBr disc) by infrared absorption spectral measurement was examined. The key band the four kinds steroid solution method two absorptions originating in functional groups at 3- 17-(or 20)-positions, for disc method, 1504 818cm-1, region from bulking agents. It thereby found that using with authors' mefhod, small amount preparations were able to analyze a short...

With the purpose of clarifying role internal factors in process dry skin occurs, was induced experimentally by an ionic surfactant and, using model system, we investiglated from a pharmacological perspective as new experimental plan. Through this research, have conceived theory explaining how occurs. Furthermore, on beais theory, developed effective compound for its treatment.In order to study mechanism which used anti-inflammatory agents and inhibitors against histological impairment...

The inclusion complexations of flurbiprofen (FP) with three cyclodextrins (α-, β-, and γ-CyD) were assessed by solubility method, optical rotatory dispersion (ORD), ultraviolet spectra (UV) circular dichroism (CD) in aqueous solution. FP was included β-CyD or γ-CyD the molecular ratio 1 : 1. Their stability constants mutual effects order >γ-, >α-CyD. To improve local irritation induced intramuscular injection eye dropping FP, CyD complexation utilized. CyDs found to protect erythrocytes from...

<title>Abstract</title> <bold>Background</bold>: In Japan, anticancer drugs are often approved based on the Objective Response Rate (ORR) when conduct of a confirmatory study is difficult or expected to take considerably long time. However, it remains unclear how frequently post-marketing studies conducted and for which indications they implemented. We aimed understand status drugs. <bold>Methods</bold>: investigated drug ORR in Japan between 2015 2022. <bold>Results</bold>: found that 60%...

An oxide removal process for InP surface using atomic hydrogen cleaning was characterized and optimized use in the selective molecular beam epitaxial (MBE) growth of InGaAs quantum structures. In-situ X-ray photoelectron spectroscopy (XPS), reflection high energy electron diffraction (RHEED), scanning microscopy (SEM) transmission (TEM) techniques were used. Detailed XPS measurements clarified effects on planar surfaces. The efficiently removed oxygen. However, P/In ratio depended...
