Biomarker discovery using mass spectrometry (MS) has recently seen a significant increase in applications, mainly driven by the rapidly advancing field of metabolomics. Instrumental and data handling advancements have allowed for untargeted metabolite analyses which simultaneously interrogate multiple biochemical pathways to elucidate disease phenotypes and therapeutic mechanisms. Although most...

background: culture media enrichment through the addition of protein hydrolysates is beneficial for achieving higher protein expression. methods: in this study, designing the optimum mixture of four soy and casein-derived hydrolysates was successfully performed by design of experiment and specific productivity increased in all predicted combinations. protein profile of recombinant cho (rcho) ce...

The mangrove plant Acanthus ilicifolius and its relative, mollis, have been previously proved to possess diverse pharmacological effects. Therefore, evaluating the differentially expressed proteins of these species under tidal flooding stress is essential fully exploit benefit from their medicinal values. roots A. mollis were exposed 6 h per day for 10 days. dry weight, hydrogen peroxide (H2O2)...

Preliminary findings indicate that PprI is a regulatory protein that stimulates transcription and translation of recA and other DNA repair genes in response to DNA damage in the extremely radioresistant bacterium Deinococcus radiodurans. To define the repertoire of proteins regulated by PprI and investigate the in vivo regulatory mechanism of PprI in response to gamma radiation, we performed co...

Background and Purpose Vulvovaginal candidiasis (VVC) is a common problem in women. The purpose of this study was to identify of Candida species isolated from vulvovaginitis woman suffering vulvovaginitis refered to Ghaem Hospital, Mashhad, Iran, by use of MALDI-TOF mass spectrometry.  Materials and Methods The 65 clinical samples isolated from Vulvovaginitis women were collected in...

While pulsed-field gel electrophoresis (PFGE) is recognized as the gold standard method for clonality analysis, MALDI-TOF MS has recently been spotlighted as an alternative tool for species identification. Herein, we compared the dendrograms of multi-drug-resistant (MDR) Acinetobacter baumannii isolates by using MALDI-TOF MS with those by using PFGE. We used direct colony and protein extraction...

BACKGROUND Edwards syndrome (ES) is a severe chromosomal abnormality with a prevalence of about 0.8 in 10,000 infants born alive. The aims of this study were to identify candidate proteins associated with ES pregnancies from amniotic fluid supernatant (AFS) using proteomics, and to explore the role of biological networks in the pathophysiology of ES. METHODS AFS from six second trimester preg...

NOD2, a cytosolic receptor for the bacterial proteoglycan fragment muramyl dipeptide (MDP), plays an important role in the recognition of intracellular pathogens. Variants in the bacterial sensor domain of NOD2 are genetically associated with an increased risk for the development of Crohn disease, a human chronic inflammatory bowel disease. In the present study, global protein expression change...
