Algorithms of maximum likelihood data clustering with applications
, 2002 We address the problem of data clustering by introducing an unsupervised, parameter free approach based on maximum likelihood principle. Starting from the observation that data sets belonging to the same cluster share a common information, we construct ...

Precise Similarity of Many Human Proteins to Proteins of Prokarya [PDF]
, 2007 Proteins originated in early forms of life and have long survived, because they have always been required. Some recognizably similar proteins are found in all sequence comparisons between species, no matter how distant, including prokaryotes and ...

The Molecular Basis of Amino Acids Sensing
Advanced Science, EarlyView.Amino acids are essential as protein building blocks and signaling molecules, enabling metabolic regulation. Cells sense amino acid levels to control protein synthesis, maintain homeostasis, and adapt to nutritional changes. This review explores recent advances in amino acid sensing mechanisms across organisms, highlighting their roles in cellular ...

Interactions between the neuromodulatory systems and the amygdala: exploratory survey using the Allen Mouse Brain Atlas. [PDF]
, 2013 Neuromodulatory systems originate in nuclei localized in the subcortical region of the brain and control fundamental behaviors by interacting with many areas of the central nervous system.

Advanced Science, EarlyView.The structure and assembly principles of a two‐component encapsulin nanocompartment shell are reported. The two‐component protein compartment self‐assembles from two distinct HK97‐fold shell proteins into a pseudo‐icosahedral protein shell with variable composition and irregular tiling.

The Juxtamembrane, Cytosolic Region of the Epidermal Growth Factor Receptor Is Involved in Association with α-Subunit of Gs [PDF]
Journal of Biological Chemistry, 1997 Previously, we have demonstrated that epidermal growth factor (EGF) can stimulate adenylyl cyclase activity via activation of Gs in the heart. Moreover, we have recently shown that Gsalpha is phosphorylated by the EGF receptor protein tyrosine kinase and that the juxtamembrane region of the EGF receptor can stimulate Gs directly.

Antiviral effects and mechanism of Qi pi pill against influenza viruses
Animal Models and Experimental Medicine, EarlyView.Qi pi pill presents anti‐influenza effect and inhibits viral replication in vitro by targeting both the viral RNA replication and the release of new viral particles. Furthermore, QPP modulates the production of proinflammatory cytokines induced by influenza infection in host cells.

Respiratory virus mRNA vaccines: mRNA Design, clinical studies, and future challenges
Animal Models and Experimental Medicine, EarlyView.Abstract Respiratory infectious diseases frequently erupt on a global scale, with RNA viruses, such as SARS‐CoV‐2, RSV, and influenza viruses, posing challenges to vaccine development due to their high mutation rates. Traditional vaccine development cycles are lengthy and struggle to keep pace with rapidly evolving viruses, whereas messenger RNA (mRNA)
