Simultaneous determination

In this study, one analytical procedure was established for simultaneous determination based on UV-Vis spectrometry coupled with several multivariate linear regress solved by Python – an open language programme to quantify three antibiotics, including TET, PGP, and CEX, in laboratoryprepared synthetic and pharmaceutical mixtures. This study also provided a universally analytical procedure for determining the three antibiotics in their pharmaceutical forms without the need for optimization for each analyte.

The combination of hydrochlorothiazide (HCT), amlodipine besylate (AML) and olmesartan medoxomil (OLM) is highly effective in treating hypertension. Currently, Vietnamese Pharmacopoeia V and other reference pharmacopoeias do not have a procedure for the simultaneous quantification of these three ingredients. Objective: To develop and validate a procedure for simultaneous determination of HCT, AML and OLM in tablets by HPLC method.

This study aimed to determine the effects of an herbal formula named TD0014 on the electrostimulationinduced erection in a rat model. Eighteen sixteen-week-old male Wistar rats were used. The intracavernous pressure and the arterial blood pressure were simultaneously monitored during cavernous nerve electrical stimulation before and after the administration of TD0014 (1.8 g/kg).

This paper deals with the non-linear least square algorithm applied to determine simultaneously equilibrium constants lg 1, lg 2; activity coefficients of ions (lg HA-, lg A2-) and of neutral molecule (lgfH2A) for aqueous solutions of fumaric, sucinat acids from pH values at different ionic forces establishzed by inert salts NaCl, NaClO, KCl, KNO3 and NaNO3. It has been shown that the calculation results of lgfH2A, lg HA-, lg A2- and lg 1, lg 2 are in a good agreement with experimental data as long as the experimental INPUT data have high precision.

The paper deals with non-linear least square algorithm applied to determine simultaneously equilibrium constant pKb or log , activity coefficients of ions HA+ and of neutral molecules fA for aqueous solution of monoprotic bases from pH data at different ionic forces established by inert salts. It has been shown that the calculation results of log HA+, logfA and log as well could be in a very good agreement the not so large number of experimental data when the experimental data are fully treated in order to receive INPUT data with high precision.

The hydrolysis of acetylthiocholine by acetylcholinesterase fromElectro-phorus electricuswas investigated in the presence of the inhibitors tacrine, gallamine and compound1. The interaction of the enzyme with the sub-strate and the inhibitors was characterized by the parametersKI , a¢, borb, Kmand Vmax, which were determined directly and simultaneously from nonlinear Michaelis–Menten plots.

Approach to the Patient: Acid-Base Disorders A stepwise approach to the diagnosis of acid-base disorders follows (Table 48-3). Care should be taken when measuring blood gases to obtain the arterial blood sample without using excessive heparin. Blood for electrolytes and arterial blood gases should be drawn simultaneously prior to therapy, since an increase in [HCO3–] occurs with metabolic alkalosis and respiratory acidosis. Conversely, a decrease in [HCO3–] occurs in metabolic acidosis and respiratory alkalosis.

Touch localization is performed by light pressure for an instant with the examiner's fingertip or a wisp of cottonwool; the patient, whose eyes are closed, is required to identify the site of touch with the fingertip. Bilateral simultaneous stimulation at analogous sites (e.g., the dorsum of both hands) can be carried out to determine whether the perception of touch is extinguished consistently on one side or the other. The phenomenon is referred to as extinction.

Segment Design Tradeoffs I. OVERVIEW The six steps in the systems-level design process associated with the software radio are illustrated in Figure 6-1. The tradeoffs proceed from front end to back end. The choice of antennas (step 1 in the figure) determines the number and bandwidth of RF channels (step 2). This, in turn, constrains the numbers and bandwidths of ADCs (step 3). Some waveforms may require dedicated ASICs (e.g., W-CDMA despreaders) in front of the ADCs. Additional parallel IF processing and ADC paths may be necessary to support multiple-service bands simultaneously....
