These data show that AR is common in the Middle East region as elsewhere in the world. Many patients with AR in Middle East region suffer from their symptoms (e.g., runny nose, nasal itching, nasal congestion, postnasal drip, and other symptoms) on all or most days during the times of the year that their allergies are worst. These symptoms have been shown to reduce QOL and performance at work/school to a significant degree. Additionally, the survey data underscore a considerable treatment gap with current therapies for AR and that many AR patients still have not found adequate effectiveness with currently available medications. Thus, through identification of disease impact on the Middle East population and highlighting treatment gaps, clinicians in the Middle East may better understand and treat AR, leading to improvements in overall patient satisfaction and QOL.
This paper re-examines the relationship between stock market development and economic growth. It provides a theoretical basis for establishing the channel through which stock markets affect economic growth in the long run. It examines the hypothesis of endogenous growth models that financial development causes higher growth through its influence on the level of investment and its productivity. The empirical part of this study exploits techniques recently developed to test for causality in VARs.The evidence obtained from a sample of four countries suggests that investment productivity is the channel through which stock market development enhances the growth rate in the long run.
Bone injuries represent
a major challenge in the medical field.
The commonly used treatments for bone regeneration rely on the use
of bone grafts that are usually associated with complications such
as donor site morbidity, disease transmission, high cost, and lack
of availability. Bone tissue engineering has become a golden solution
for the repair of bone injuries by regenerating the damaged biological
tissues using biocompatible scaffolds. However, most of the tissue
engineered scaffolds do not possess the combined properties of high
elasticity, appropriate stiffness, biocompatibility, osteoinductivity,
and antimicrobial properties. In this study, we engineered bioactive
and antimicrobial nanocomposites that can promote bone formation while
simultaneously provide a barrier against bacterial infections commonly
associated with bone implants. We used PEGylated polyglycerol sebacate
as nanocomposites base, which was functionalized with Laponite nanosilicates,
a synthetic nanoclay, and an antimicrobial peptide (AMP). The successful
synthesis of the PEGylated polyglycerol sebacate and Laponite incorporation
within the nanocomposites were confirmed through nuclear magnetic
resonance (NMR) and Fourier transform infrared spectroscopy (FTIR).
The scaffolds had an elastic modulus and ultimate tensile strength
within a range of 3.8–4.7 MPa and 1.5–3 MPa, respectively.
Furthermore, the scaffolds loaded with antimicrobial peptide exhibited
a significant antimicrobial activity against both Gram-negative (Escherichia coli) and Gram-positive (Staphylococcus
aureus) bacteria. The in vitro cytocompatibility tests showed
>90% viability of preosteoblast (W-20-17) cells. Moreover, in vitro
differentiation assays demonstrated the scaffolds’ ability
to promote osteogenic differentiation of W-20-17. Collectively, the
nanocomposites containing Laponite and antimicrobial peptide were
proven to have osteoinductive and antimicrobial activity, making them
desirable for bone tissue engineering applications.
This study investigates how the implementation of Enterprise Risk Management program affects the performance of firms using an Enterprise Risk Management model for the banking sector and an integrated model for measuring Enterprise Risk Management index used in the study by Mukhtar and Soliman (2016). Ten listed commercial banks were selected with the Enterprise Risk Management index as the main independent variable, with Return on Average Equity (ROAE), Share Price Return (SPR) and Firm Value (FV) used as three separate dependent variables. The study provides strong evidence of a positive relationship between Enterprise Risk Management implementation and performance in the Nigerian banking sector. The findings and conclusions of this study are consistent with those of other studies that used data from different industries, providing a basis from which to generalize the findings from this study to firms in other industries.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
