Mass spectrometry is the most used method for protein identification and quantification. Here we developed four protein extraction protocols precisely for mass spectrometry, and we compared with other ones already published. The best protocol developed by us consists on a simple extraction solution, a heat-shock step, and does not use protease inhibitor; moreover, it is the most efficient and uniform among replicates, besides to be safe, cheap and fast. That method also provided the highest number of proteins uniquely identified and allows finding a diversity of protein classes, which their absence is a problem to be avoided.

Advancements in clinical chemistry have major implications in terms of public health, prompting many clinicians to seek out chemical information to aid in diagnoses and treatments. While mass spectrometry (MS) and hyphenated-MS techniques such as LC-MS or tandem MS/MS have long been the analytical methods of choice for many clinical applications, these methods routinely demonstrate difficulty in differentiating between isomeric forms in complex matrices. Consequently, ion mobility spectrometry (IM), which differentiates molecules on the basis of size, shape, and charge, has demonstrated unique advantages in the broad application of stand-alone IM and hyphenated IM instruments towards clinical challenges.

This investigation represents a pioneering effort to examine the therapeutic effects of PCB specifically in the context of CFA-induced mice, as well as to elucidate the underlying mechanisms that facilitate such effects. Our study utilized advanced methodologies, namely high-performance liquid chromatography coupled with mass spectrometry (HPLC-MS)-based metabolomics, alongside comprehensive multivariate data analysis, to identify a distinctive metabolic profile associated with acute inflammation. Through our analyses, we discovered that several potential metabolites were significantly implicated in a variety of critical metabolic pathways.

In the past few years, three protein molecules-USP53, NPY2R, and DCTN1-AS1-have garnered significant attention in scientific research due to their potential implications in tumor development. Mass spectrometry and proteomics techniques were used to analyze the three-dimensional structure of these protein molecules and predict their active sites and functional domains. The effects of USP53, NPY2R and DCTN1-AS1 on biological behavior of tumor cells were studied by constructing gene knockout and overexpression cell models.

Inhaled nitric oxide (iNO) is a selective pulmonary vasodilator that is used as a treatment for persistent pulmonary hypertension in neonates (PPHN) with hypoxic respiratory failure. The generation of reactive oxygen and nitrogen species might induce oxidative/nitrosative damage to multiple organs. There is an increasing scientific and clinical interest in the determination of specific biomarkers to measure the degree of oxidative/nitrosative stress in non-invasively collected biofluids.
