BACKGROUND The formation of bacterial biofilms on urinary catheters is a leading cause of urinary tract infections in intensive care units. Cytobacteriological examination of urine from patients is often misleading, due to the formation of these biofilms. Therefore, characterizing these biofilms and identifying the bacterial species residing on the surface(More)
MYOC encodes a secretary glycoprotein of 504 amino acids named myocilin. MYOC is the first gene to be linked to juvenile open-angle glaucoma (JOAG) and some forms of adult-onset primary open-angle glaucoma (POAG). The gene was identified as an up-regulated molecule in cultured trabecular meshwork (TM) cells after treatment with dexamethasone and was(More)
Trans fatty acids (TFAs) mainly arise from 2 major sources: natural ruminal hydrogenation and industrial partial catalytic hydrogenation. Increasing evidence suggests that most TFAs and their isomers cause harmful health effects (that is, increased risk of cardiovascular diseases). Nevertheless, in spite of the existence of an international policy consensus(More)
INTRODUCTION Trans-fatty acids (TFAs) can be produced either from bio-hydrogenation in the rumen of ruminants or by industrial hydrogenation. While most of TFAs' effects from ruminants are poorly established, there is increasing evidence that high content of industrial TFAs may cause deleterious effects on human health and life span.

Nanoporous sol-gel glasses were used as host materials for the encapsulation of apomyoglobin, a model protein employed to probe in a rational manner the important factors that influence the protein conformation and stability in silica-based materials. The transparent glasses were prepared from tetramethoxysilane (TMOS) and modified with a series of mono-,(More)
Organically-modified siloxanes were used as host materials to examine the influence of surface chemistry on protein conformation in a crowded environment. The sol-gel materials were prepared from tetramethoxysilane and a series of monosubstituted alkoxysilanes, RSi(OR')(3), featuring alkyl groups of increasing chain length in the R-position. Using circular(More)
BACKGROUND Vitis vinifera 'muscat hamburg' (Vitaceae) is a blue-black grape variety commonly found in Pakistan. It has been consumed and used in traditional medicine for centuries. Compared to other grapes, M. hamburg records one of the greatest amount of polyphenols and displays potent antioxidant activities, which make it a great candidate for its(More)
The discovery of the interesting intrinsic properties of graphene, a two-dimensional nanomaterial, has boosted further research and development for various types of applications from electronics to biomedicine. During the last decade, graphene and several graphene-derived materials, such as graphene oxide, carbon nanotubes, activated charcoal composite,(More)
Adrenocortical carcinoma (ACC) is a rare but aggressive malignancy with a poor prognosis. Treatment options for advanced ACC are limited. Indeed, radical tumor resection can lead to local or metastatic recurrence, and mitotane (Lysodren(®)), the only recognized adrenolytic drug, offers modest response rates, notably due to some of its physico-chemical and(More)
Carbon-Fluorine Spectroscopy (CFS(TM)), also known as Fluoro-Raman Spectroscopy (FRS(TM)), is a relatively new patented platform technology using a family of various methods and cost-effective devices called PLIRFATM (Pulsed Laser Isochronic Raman and Fluorescence Apparatus) developed by Fluorotronics, Inc. The key feature of this progressive and(More)
