A simplification of the laminin nomenclature is presented. Laminins are multidomain heterotrimers composed of alpha, beta and gamma chains. Previously, laminin trimers were numbered with Arabic numerals in the order discovered, that is laminins-1 to -5. We introduce a new identification system for a trimer using three Arabic numerals, based on the alpha, beta and gamma chain numbers. For example, the laminin with the chain composition alpha5beta1gamma1 is termed laminin-511, and not laminin-10. The current practice is also to mix two overlapping domain and module nomenclatures. Instead of the older Roman numeral nomenclature and mixed nomenclature, all modules are now called domains. Some domains are renamed or renumbered. Laminin epidermal growth factor-like (LE) domains are renumbered starting at the N-termini, to be consistent with general protein nomenclature. Domain IVb of alpha chains is named laminin 4a (L4a), domain IVa of alpha chains is named L4b, domain IV of gamma chains is named L4, and domain IV of beta chains is named laminin four (LF). The two coiled-coil domains I and II are now considered one laminin coiled-coil domain (LCC). The interruption in the coiled-coil of beta chains is named laminin beta-knob (Lbeta) domain. The chain origin of a domain is specified by the chain nomenclature, such as alpha1L4a. The abbreviation LM is suggested for laminin. Otherwise, the nomenclature remains unaltered.

Background: Pathological tau accumulation is the primary constituent of neurofibrillary tangles and other tau aggregates seen in various neurodegenerative diseases collectively known as tauopathies. Recently, immunotherapeutic strategies focused on tau have shown promise in reducing tauopathy in both cellular and animal models.
Method: We previously used humanized yeast models to purify recombinant hyper-phosphorylated human Tau for mouse immunizations and the isolation of a high-affinity anti-Tau monoclonal antibody (mAb) with enhanced diagnostic and prognostic capacities.

Pressure overload induces pathological cardiac remodeling, including cardiac hypertrophy and fibrosis, resulting in cardiac dysfunction or heart failure. Recently, we observed that the low-density lipoprotein receptor-related protein 6 (LRP6), has shown potential in enhancing cardiac function by mitigating cardiac fibrosis in a mouse model subjected to pressure overload. In this study, we investigated the role of LRP6 as a potential modulator of pressure overload-induced cardiac hypertrophy and elucidated the underlying molecular mechanisms.

Preeclampsia (PE) is a common hypertensive disease in women with pregnancy. With the development of bioinformatics, WGCNA was used to explore specific biomarkers to provide therapy targets efficiently. All samples were obtained from gene expression omnibus (GEO), then we used a package named "WGCNA" to construct a scale-free co-expression network and modules related to PE.

In an elicited production test, Devitt and Porot prompt participants to use proper names to compare the Descriptivist Theory and the Causal-Historical Theory on proper names' reference. According to the Descriptivist Theory, names refer to the entity that fulfills the description that speakers associate with them.

Polysaccharide extracted from Grifola frondosa (GFP) was selected in this study. After preliminary separation, four factions were collected, named GFP-F1, GFP-F2, GFP-F3 and GFP-F4. GPF-F2 was further separated into two fractions, namely GFP-N1 and GFP-N2.
