A new series of N-(5-Mercapto-1,3,4-thiadiazol-2-yl)-2-phenylacetamide derivatives (3a-3j) were synthesized via an amidation reaction using EDC and HOBt in acetonitrile solvent at room temperature condition. Chemical structures were characterized by 1H NMR, IR and MS spectroscopic methods and related melting points were also determined. The anticancer activity was evaluated using MTT procedure ...

MicroRNAs (miRNAs) are a large family of non-coding RNAs that are evolutionarily conserved, endogenous, and 21-23 nucleotides in length. miRNAs regulate gene expression by targeting messenger RNAs (mRNAs) by binding to complementary regions of transcripts to repress their translation or mRNA degradation. miRNAs are encoded by the genome, and more than 1000 human miRNAs have been identified so f...

The increasing role of hair analysis in forensic toxicological investigations principally owes to recent improvements of mass spectrometric instrumentation. Research achievements during the last 6 years in this distinctive application area of analytical toxicology are reviewed. The earlier state of the art of hair analysis was comprehensively covered by a dedicated book (Kintz, 2007a. Analytica...

Customary approaches to setting safe upper levels for the intake of nutrients use, as critical events, adverse health that which, when adjusted using uncertainty factors (UF), produce values that, when they are applied to population risk analysis, along with dietary reference values that have been independently derived using a different approach by nutritionists, may provide narrow and unrealis...

We briefly comment on the state of clinical toxicology in Navarra and in the rest of Spain, with reference to the Toxicology Committee of Navarra and its aims. Epidemiological data from the Emergency Service of the Hospital of Navarra is presented, as well as where to find information on the subject; the epidemiological registration sheet designed by the SEMESTOX group is attached. A descriptio...

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...

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 (...
