Antifouling peptide surfaces have garnered increasing attention due to their immense potential across various biochemical fields. Cyclic peptides, in particular, demonstrate greater resistance nonspecific substance adsorption compared regular linear peptides. Herein, inspired by the macrocyclization method, we introduced two non-natural amino acids (R8 and S5) cyclize typical low-fouling sequence (EKEKEK) head-to-tail, thereby protecting terminal reducing proteolytic susceptibility. This...

The E. coli single-stranded DNA-binding protein (SSB) is essential to viability. It plays key roles in DNA metabolism where it binds nascent single strands of and target proteins known as the SSB interactome. There are >2,000 tetramers per cell with 100-150 associated genome at any one time, either replication forks or sites repair. remaining 1,900 could constantly diffuse throughout cytosol be inner membrane observed for other metabolic enzymes. To visualize localization ascertain potential...

Numerous studies have demonstrated that microRNAs (miRNAs) play a key role in human carcinogenesis and metastasis. For example, miR‑299‑5p has previously been revealed to be dysregulated several cancers. However, the biological function of breast cancer remains unclear. The present study was downregulated tissues cell lines. restoration expression suppressed migration invasion, whereas inhibition promoted invasion. In addition, vivo overexpression able inhibit tumour metastasis nude mice....

EV71 is one of the most common pathogens causing HFMD in young children, and some patients experience severe or fatal neurological consequences. To ensure efficient replication, virus must hijack multiple host factors for its own benefit.

Clouston syndrome (CS; also termed hidrotic ectodermal dysplasia) is a rare autosomal dominant genetic skin disorder, characterized by alopecia, nail dystrophy, and palmoplantar hyperkeratosis. Mutations in the GJB6 gene, which encodes gap junction protein connexin 30, have been shown to cause this disorder. To date, four mutations of found patients with CS: G11R, V37E, D50N A88V. GJA1 (V41L) GJB2 (R127H) are related CS. We novel missense mutation, N14S, previously identified F191L mutation...

Abstract Controversial results have been reported about the association of calcium, magnesium, and phosphorus stroke risk, but none in China. To investigate between dietary phosphorus, incidence Chinese adults, we collected data from China Health Nutrition Survey (CHNS) 2004 to 2011, including 6411 participants aged 45–79 years free at baseline. Diet was assessed by interviews combining 3-d 24-h food recalls household inventory weighing each survey round. The incident identified based on...

Articles on how to extract high voltage power line targets from resolution SAR images is limited due too many uncertainties in the data processing. In this paper, some 1m and 3m X-band radar were selected China area. This paper analyzed compared backscatter characters of transmission towers lines under HH VV polarization mode. TerraSAR used analyze spatial geometry lines' scattering. The result showed that if angle between direction azimuth changed, scattering magnitude location changed...

A novel probe-type thin film thermocouple has been fabricated successfully for high temperature measurement applications.
