microRNAs (miRNAs) are a large family of small regulatory RNA molecules found in all multicellular organisms. Since their discovery in 2001, there has been impressive progress in miRNA research, and a great deal is now known about the biosynthesis of miRNAs and their regulatory role in translation. It is becoming increasingly clear that miRNAs have fundamental roles to play in cellular response...

The rapid emergence of gold nanoparticles (AuNPs) technology holds great promise for future applications due to their large volume specific surface areas with high diverse surface activities than bulk gold. These properties have made AuNPs of great importance in the development of excellent nanoelectronic chips, promising vehicle for a wide range of biomedical and environmental applications. Ho...

Statistical-learning methods have been developed for facilitating the prediction of pharmacokinetic and toxicological properties of chemical agents. These methods employ a variety of molecular descriptors to characterize structural and physicochemical properties of molecules. Some of these descriptors are specifically designed for the study of a particular type of properties or agents, and thei...

objective one of the prominent microorganisms in several reports of nosocomial infections is staphylococcus aureus (s. aureus) which is carried by several health care workers (hcw) many times throughout the day. the present investigation was conducted to assess the nasal and hand carriage rate of s. aureus amongst medical personnel of loghman hakim hospital's toxicological intensive care unit (...

Background and objectives: Nigella sativa is a delicate floral vegetable belonging to Ranunculaceae family. Thymoquinone (TQ) is the dominant active component in Nigella sativa seed oil which has a variety of pharmacological properties such as antioxidant, anticancer, anti-inflammatory and analgesic activities. However, TQ is a quinone derivative, which may le...

Many Organothallium Compounds have been used in medicine, industry and antibacterial activity. Optical properties are among the most fascinating and useful properties of many complexes and have been extensively studied using a variety of optical spectroscopic techniques. A basic understanding of the optical properties and related spectroscopic techniques is essential for characterization about ...
