Nestin Forms a Flexible Cytoskeleton by Means of a Huge Tail Domain That Is Reversibly Stretched and Contracted by Weak Forces.

Nestin is a type VI intermediate filament protein and a well-known neural stem cell marker. It is also expressed in high-grade cancer cells, forming copolymerized filaments with vimentin. We previously showed that nestin inhibits the binding of vimentin's tail domain to actin filaments (AFs) by steric hindrance through its large nestin tail domain (NTD), thereby increasing three-dimensional cytoskeleton network mobility, enhancing cell flexibility, and promoting cancer progression.

Urinary continence outcomes after robot-assisted laparoscopic radical prostatectomy: Significance of anterior reconstruction.

Objective: Urinary continence after radical prostatectomy is a crucial aspect of patient quality of life. The aim of this study was to identify the factors influencing urinary continence after robot-assisted laparoscopic radical prostatectomy, focusing on the role of anterior reconstruction.

Methods: We collected clinical data from 375 patients at a single institution.

Fibrillin-1 G234D mutation in the hybrid1 domain causes tight skin associated with dysregulated elastogenesis and increased collagen cross-linking in mice.

Fibrillin-1, an extracellular matrix (ECM) protein encoded by the FBN1 gene, serves as a microfibril scaffold crucial for elastic fiber formation and homeostasis in pliable tissue such as the skin. Aside from causing Marfan syndrome, some mutations in FBN1 result in scleroderma, marked by hardened and thicker skin which limits joint mobility. Here, we describe a tight skin phenotype in the Fbn1 mice carrying a corresponding variant of FBN1 in the hybrid1 domain that was identified in a patient with familial aortic dissection.

Nanoscale chirality generated in zinc(II) orthophosphate clusters: evidence by vibrational circular dichroism.

Layered zinc(II) hydroxides (LZH) intercalating the deprotonated forms of -(-) or -(+)-1,1'-binaphthyl-2,2'-diyl hydrogenphosphate (denoted as - or -BNDHPH, respectively) were prepared from Zn(NO) at pH 5 and 60 °C by the mixing method. The obtained hybrid compounds (denoted as - or -BNDHP/LZH, respectively) were heated from room temperature up to 800 °C under nitrogen atmosphere. According to the thermal gravimetric/differential thermal analysis measurements, hydroxyl groups were dehydrated at 270-400 °C, followed by the decomposition of organic components at 420-600 °C.
