The generated data were mathematically represented using the Jouyban−Acree model. The correlated mole fraction solubilities are in good agreement with the corresponding experimental values as documented by an overall mean percentage deviation of 2.3 %. Densities of TRIS saturated solutions in water and 1-propanol at various temperatures were measured and employed to predict the density of TRIS saturated solutions in their binary solvent mixtures using a well-established method. Buffering agents dissolved in mixed solvents are used as mobile phases and/or background electrolytes in analytical separation

The mole fraction solubility decreased nonlinearly with increasing mass fraction of PEG 400, less pronounced in the water-rich range, steeper with increasing mass fractions of PEG 400 of about 0.6. The highest mole fraction solubility of the salt was 0.1004 measured in neat water at 313.2 K, the lowest solubility was 0.0352 at 293.2 K in pure PEG 400. For the purpose of obtaining solubilities at temperatures and solvent compositions others than the measured ones the following correlation models were applied: The Yalkowsky, the van't Hoff, the combined nearly ideal binary solvent/Redlich-Kister (CNIBS/R-K), the Jouyban-Acree, and the van't Hoff-Jouyban-Acree model. The Overall Mean Percentage Deviation (OMPD) and Mean Percentage Deviation (MPD) were used to evaluate the constructed models for the entire set of the fifty-five data and for the sub-sets of the solubilities, respectively. The lowest OMPD values of 0.6% and 1.2%, respectively, and thus the best prediction abilities, exhibited the van't Hoff and the CNIBS/R-K models. The van't Hoff-Jouyban-Acree model with OMPD of 4.9% allows the calculation of the solubility at any temperature and at any solvent composition by a single model equation.

The measured mole fraction solubility of citrate was around 5 × 10− 2 in pure water and decreased by one order of magnitude to 5 × 10− 3 at mole fraction of methanol of 0.3 in the binary mixture; within the investigated composition of the mixed solvent the solubility remained then at a low level and was about 10− 4 at methanol mole fraction of 0.69. In all solvents the solubility increased with increasing temperature; the effect was more pronounced in the mixed solvents than in the pure aqueous solution. In order to extend the solubility data for practical applications, the experimental values were correlated to a semi-empirical combined model of Jouyban-Acree and van't Hoff, resulting in calculated solubilities which agreed with the experimental ones within a mean percentage deviation (MPD) of approximately 10.8%.

The obtained linear range for the determination of MTX was 0.02-10 μg/mL. The detection limits (signal: noise = 3) was 0.015 μg/mL and the relative standard deviation for replicated determinations of 1 μg/mL of MTX was 1.9%. The proposed method is a simple, practical and relatively free from interference effects and was successfully applied to assess MTX in urine, serum and samples of an injection solution.

There are some methods for adjustment of drugs solubility and the cosolvensy method is the feasible method in practice. Beside the experimental determination of the solubility drugs in mixed solvents, there are some methods to predict the solubility and the Jouyban-Acree model is the most accurate one among similar models. To extend the available solubility database, solubility of ranitidine in binary and ternary mixtures of PEGs 200 and 400, ethanol and propylene glycol at 25ºC. Methods: To reach the equilibrium condition, excess amount of ranitidine added to the prepared solvent mixtures. The solutions were saturated in an incubator equipped with a temperature-controlling system maintained constant at 25 (±0.2) ºC using a shaker. The solutions were saturated after 72 h. The saturated solutions were filtered and diluted by water. The absorbance of preparated solutions were determined at 325 nm. The obtained data were fitted to the Jouyban-Acree model to get model constant values and the trained model was used for predictions of binary and ternary mixtures of PEGs 200 and 400,ethanol and propylene glycol at 25oC. Results: The results showed that the solubility of ranitidine in ethanol+PEG 400, 200, PG mixtures was increased with addition of PEG400, 200 and PG at 25 oC. The maximum dissolved concentration of ranitidine at ethanol+PEG400, ethanol+PEG200 and ethanol+PG were observed in 0.3, 0.2 and 1.0 (ethanol mass fraction), respectively. The results were correlated and predicted by the Jouyban-Acree model and the prediction error was less than 10%. Conclusions: The trained model can provide more accurate results for prediction of the solubility of RH in binary and ternary solvent mixtures. As a result of this model, the number of required experimental data is reduced.

Using this probe, fluorescence signals was emitted by Tb@KCC-1-NH2-FA at 490 nm by applying 380 nm as excitation wavelength. The reported probe is based on the interaction between FA decorated on the surface of Tb@KCC-1-NH2-FA and folate receptor (FR) which is overexpressed on the surface of the most of cancer cells. Fluorescence microscopy and flow cytometry were utilized to verify the uptake of Tb@KCC-1-NH2-FA with FR-positive HT 29 cancer cells. The specificity of Tb@KCC-1-NH2-FA towards FR-positive cells was approved by staining HEK 293 cells as FR-negative cells with Tb@KCC-1-NH2-FA which obtained results approved selective differentiation of normal cells with the FA-decorated nanomaterials. The cytotoxicity of Tb@KCC-1-NH2-FA was evaluated by MTT assay which confirmed their biocompatible nature. Under optimum conditions, this cytosensor is able to detect HT 29 colon cancer from 500 to 6.5 × 103 cells/mL with lower limit of detection (LLOQ) of 500 cells/mL. Due to the room temperature stability of Tb@KCC-1-NH2-FA, this cytosensor could be developed in a simple way with exceptional specificity which may show potential applications for early stage detection of colon cancer.

To decrease the mortality of cancer, early stage detection of cancer is of great importance. An innovative platform was developed for differentiation and detection of HT 29 cancer cells based on interactions between folate (FA) and folate receptors (FRs) of the membrane of cancer cells. In summary, FA and cysteamine (CA)-functionalized gold nanoparticles (AuNPs) were synthesized and characterized by field emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), dynamic light scattering (DLS) and Fourier-transform infrared (IR) spectroscopy. Also, the surface charge was determined by measuring of the zeta potential. Fluorescence imaging and flow cytometry analyses were used to approve the selective uptake of the synthesized probe to the cancer cells. HEK 293 FR-negative cells were applied to assess the selectivity of AuNPs/CA/FA towards FR-negative cells. The differential pulse voltammetry (DPV) technique was used to determine the HT 29 cells from 250 to 5000 cells/mL with a lower limit of quantification (LLOQ) of 250 cells/mL. The produced AuNPs/CA/FA based nanoprobe could not only detect the signaling of HT 29 cells but also improve the specificity of cytosensor towards FR-positive cancer cells. According to the obtained results, the newly developed nano-probe could be used as a portable biomedical device for cancer diagnosis.

Percent average relative deviations (%ARD) of the predicted and experimental values were calculated as an accuracy criterion and were obtained as 19.1 and 20.1 by considering the theoretical and experimental Abraham parameters, respectively. The collected data were also correlated using the Jouyban-Acree model, which is resulted in the overall %ARDs of 16.8 and 18.1 for back-calculated data by regarding the theoretical and experimental Abraham parameters, respectively. Moreover, to update the previously proposed global model, the earlier data were merged with the collected data from recent publications and total data sets were used to retrain the global Jouyban-Acree model by regarding the theoretical and experimental Abraham parameters. Comparing %ARD of the proposed model using correlated newly data and total (new and earlier) data sets show no statistically significant difference while there is a meaningful difference between calculations by considering the theoretical and experimental Abraham parameters. Moreover, to compare the capability of the Jouyban-Acree model for correlating viscosities of binary liquid mixtures, the overall %ARD were determined and compared to three selected models; Wilson, Katti and Chaudhary, and Eyring-NRTL. The order of the amount of obtained %ARD are Jouyban-Acree

Any changes in insulin secretion level can be resulted in various diseases including diabetes, kidney failure, obesity, neurodegenerative disease and myocardial infarctions. Thus, ultrasensitive and specific recognition of insulin is crucial for early stage diagnosis and treatment of diseases. This review summarizes the trends on the use of advanced nanomaterials towards biosensing of insulin. In comparison with the conventionally used materials in sensing applications, nanomaterials can enhance the sensitivity of methods because of their exponentially increase in the surface-to-volume ratio. This feature of the nanomaterials is the main factor for designing of the point-of-care (POC) devices. Categorization and analyzing of the materials trends not only highlight the favorable features of each material but also can guide the future studies trends to the most potentially materials. Therefore, various type of nanomaterials including carbon, gold, silver, magnetic, polymer, silica and metal based materials with different biosensing techniques such as optical, electrochemical and quartz crystal microbalance for insulin detection was discussed in this review. We report most recent advances in insulin detection from Jan 2010 to Feb 2019 with discussions on their advantages and limitations. The analytical figures of merit of the developed methods are also evaluated.

Developing accurate and effective techniques to the early stage diagnosis of cancer are very vital to start the treatment process. Targeted detection of the cancerous cell is the most reliable approach to the identification of cancer solid tumors. Folate receptor (FR) is overexpressed on the membrane of many types of cancers and is a fascinating molecule for targeting cancer because of the high affinity between FR and folic acid (FA) (Kd ≈ 10 pM). Such fact was extremely utilized to develop the imaging of solid tumors and targeted delivery of drugs. This review discusses the critical role of FRs for the quantitative recognition of cancer cells. In this regard, the applied advanced materials in the designing of the FR-based cytosensors and the state-of-art of the cytosensing devices were discussed that may be have possible uses as a device in the clinical diagnosis of various cancers. Also, the analytical performances and the favorable features of the reported methods were explored. The present review covers the reported FR-based methods for the detection of cancer cells from 2010 to 2019 and will be a useful reference for the future works. Moreover, the applications of FR-based strategy in cancer cells imaging were also discussed.

Breathomics, as a branch of metabolomics is developing in various frontiers, for early and noninvasive monitoring of disease. This review starts with a brief introduction to metabolomics and breathomics. A number of important technical issues in exhaled breath collection and factors affecting the sampling procedures are presented. We review the recent progress in metabolomics approaches and a summary of their applications on the respiratory and non-respiratory diseases investigated by breath analysis. Recent reports on breathomics studies retrieved from Scopus and Pubmed were reviewed in this work. We conclude that analyzing breath metabolites (both volatile and nonvolatile) is valuable in disease diagnoses, and therefore believe that breathomics will turn into a promising noninvasive discipline in biomarker discovery and early disease detection in personalized medicine. The problem of wide variations in the reported metabolite concentrations from breathomics studies should be tackled by developing more accurate analytical methods and sophisticated numerical analytical alogorithms.
