Lateral flow biosensor development for the visual identification of H1N1 virus based on primer extension nucleic acid isothermal amplification and M13mp18 single-stranded DNA.

A lateral flow biosensor was developed based on newly established primer extension nucleic acid isothermal amplification (PEIA) and M13mp18 single-stranded DNA (ssDNA) to visually identify the H1N1 virus. The PEIA process was primer based on a template to continuously extend multiple repeat sequences, using DNA polymerase, to form long ssDNAs. M13mp18 ssDNA was then coupled to multiple long ssDNAs from PEIA and functionalized in a signal tag DNA nanostructure (STDN) for the lateral flow biosensor.

Brain re-expansion predict the recurrence of unilateral CSDH: A clinical grading system.

Objective: Assessing the risk of postoperative recurrence of chronic subdural hematoma (CSDH) is a clinical focus. To screen the main factors associated with the perioperative hematoma recurrence. The brain re-expansion is the core factor of recurrence.

Pituitary Stalk Interruption Syndrome.

Pituitary stalk interruption syndrome is a congenital disease with isolated growth hormone deficiency or multiple anterior pituitary hormone deficiencies. Here, the authors report a 22-year-old female presenting with growth retardation for 13 years. Growth hormone replacement therapy was performed when the patient was young, so her height improved.
