Abstract:
Micro- and nano-carrier formulations have been developed as drug delivery systems for active pharmaceutical ingredients (APIs) that suffer from poor physico-chemical, pharmacokinetic, and pharmacodynamic properties. Encapsulating the APIs in such systems can help improve their stability by protecting them from harsh conditions such as light, oxygen, temperature, pH, enzymes, and others. Consequently, the API’s dissolution rate and bioavailability are tremendously improved. Conventional techniques used in the production of these drug carrier formulations have several drawbacks, including therma

Abstract:
The investigation of the usability of solid insoluble β-cyclodextrin polymers (βCDP) in micro-sized, controlled drug delivery systems has only recently attracted interest. Our aim was to form complexes with poorly soluble active pharmaceutical ingredients (APIs) with two types of βCDP for drug delivery applications. Solid insoluble cyclodextrin polymer of irregular shape (βCDPIS) and cyclodextrin microbeads (βCDPB) were used in the experiments. Morphology, surface area, size distribution and swelling capacity of carriers were investigated. We created complexes with two APIs, curcumin and estra

A selected active pharmaceutical ingredient must be incorporated into a cargo carrier in a particular manner so that it achieves its goal.

Abstract:
Amorphous solid dispersion (ASD) technology is often used as a promising strategy to improve the solubility of active pharmaceutical ingredients (APIs). ASDs allow APIs to be dispersed at the molecular level in a polymer carrier, destroying the crystalline structure of the APIs and, thanks to the polymer, providing long-term supersaturation in solution. However, stability issues are an obstacle to the development of new medications with ASD. In addition to the molecular mobility at elevated temperatures leading to the crystallization of APIs, moisture affects the physical stability of ASD, lea

To our best knowledge, this is the first attempt aimed at developing ASDs via the electrospinning technique in the form of fibers containing LPV and RTV.

The remarkable olfactory power of insect species is thought to be generated by a combinatorial action of G-protein-coupled olfactory receptors (ORs) and olfactory carriers. Two such carrier gene families are found in insects: the odorant binding proteins (OBPs) and the chemosensory proteins (CSPs). In olfactory sensilla, OBPs and CSPs are believed to deliver hydrophobic air-borne molecules to ORs, but their expression in non-olfactory tissues suggests that they also may function as general carriers in other developmental and physiological processes. ¶ Bioinformatics and experimental approac

Abstract:
There is an urgent need to find effective presymptomatic Alzheimer's disease (AD) treatments that reduce the risk of AD symptoms or prevent them completely. It currently takes too many healthy people, too much money and too many years to evaluate the range of promising presymptomatic treatments using clinical endpoints. We have used brain imaging and other measurements to track some of the earliest changes associated with the predisposition to AD. We have proposed the Alzheimer's Prevention Initiative (API) to evaluate investigational amyloid-modifying treatments in healthy people who, based o

Spectacular developments that were recorded in the field of software engineering in recent years have led to the influx of software industry with series of computer apps such as dating apps, games apps, entertainment apps, banking apps, Photoshop apps, meetings and virtual conferencing apps. Studies have shown that most computer apps are widely accessible to adults and juveniles to download and effortlessly navigate through them. However, researchers have now revealed the existence of malware apps as new groups of computer apps that are strongly competing with legitimate computer apps and the

The purpose of this article was to apply the modified technology acceptance model (TAM) to examine factors influencing consumers' intention and actual behavior in using sports brand apps. Convenience sampling was conducted for Korean consumers (N = 261) of sports brand apps. Data were analyzed by partial least squares structural equation modeling (PLS-SEM) using SmartPLS 3.0. The results found that the level of enjoyment had a significantly positive effect on the perceived ease of use, while perceived ease of use also positively affected perceived usefulness.

Abstract Corrosion immersion tests of 3%Cr steel and API X65 pipeline steel were carried out in the high-pressure high-temperature autoclave, in order to simulate the typical corrosion environment of oil and gas transported pipeline. The effects of temperature and CO2 partial pressure on corrosion behaviors were investigated, and the purpose of this paper was to compare the corrosion resistance of 3%Cr steel with API X65 pipeline steels in CO2 corrosion environment. The results show that, the corrosion of both 3%Cr steel and API X65 pipeline steel were slight in mild corrosion environment, so

Abstract The radiant tubes in fired heaters operating in the creep range are designed as per API 530. The typical creep design life of the heater tubes is 100,000hours. Tube sample from this 1st Inter-heater was removed after 166,500hours of operation with the process gas outlet temperature of 550°C (1022°F). The tube skin temperature was observed in the range of 600-630°C. Scale characterization using SEM/EDS, Hot and ambient tensile testing, Hardness measurement, Accelerated Creep rupture testing and creep testing was carried out as part of the assessment.

Abstract Laboratory testing of different types of materials have been traditionally carried out using very severe brine environments. Several types of tables and graphics for material selection have thus been produced. However, relative little effort has been made to correlate actual field performance to laboratory testing.

Abstract Current testing standards provide details on how to determine Critical Stress Intensity Factor (KISSC) of C110 material (microalloyed AISI 4130 steel – UNS G41300) in 100% and 7% H2S. At 100% H2S, American Petroleum Institute (API)1 and National Association of Corrosion Engineers International (NACE)2 require a non-buffered Solution A for testing. For testing in 7% H2S, the test solution is buffered at pH 4.0 and N2 is the carrier gas. The European Federation of Corrosion Publication 16 (EFC)3 recommends a different test environment, in which the test solution is buffered to pH 4.5 fo

Abstract A laboratory investigation of application limits of 13Cr steel was carried out for sweet downhole environments in the CO2 partial pressure regime up to about 10 bar (1 MPa). Two grades of 13Cr steel were studied, one complying with the API 5CT specification and the other a higher carbon version. Polarisation curves, taken at various times after immersion of the specimens in simulated brine, revealed an increasing pitting tendency for the higher chloride levels and indicated better performance for the API 5CT grade. This was in agreement with evidence for chromium depleted zones in the

The experiments were carried out in single and two-phase flows at different gas-liquid velocity combinations at a constant pH of 3.4 and at non-controlled pH conditions. The corrosion rates correlate well with the API RP 14E c-values.
