Cactus-Inspired Janus Membrane with a Conical Array of Wettability Gradient for Efficient Fog Collection.

Fog collection plays an important role in alleviating the global water shortage. Despite great progress in creating bionic surfaces to collect fog, water droplets still could adhere to the microscale hydrophilic region and reach the thermodynamic stable state before falling, which delays the transport of water and hinders the continuous fog collection. Inspired by lotus leaves and cactuses, we designed a Janus membrane that functions to both collect fog from the air and transport it to a certain region.

[Analysis of ring chromosome 9 syndrome with fluorescence in situ hybridization].

Objective: To investigate the mechanism of the ring chromosome 9 formation by cytogenetic analysis of one case affected with ring chromosome 9 syndrome.

Methods: Routine chromosome GTG-binding analysis and dual-color fluorescence in situ hybridization (FISH) with TelVision 9p and 9q probes were applied to characterize the case.

Results: The G-binding revealed that the patient had ring chromosome 9 with the following karyotype: 45,X,-9/46,XX,r(9)(p24q34)/46,XX,r(9;9)(p24q34;p24q34)[4/92/4].

[Analysis of the small supernumerary marker chromosome in Turner syndrome with 45, X/46, X, + mar karyotype].

Objective: To identify the origin and study the morphology of small supernumerary marker chromosome (sSMC) in Turner syndrome with 45, X/46, X, + mar karyotype.

Methods: Using the conventional chromosome G-banding technique, 10 cases of Turner syndrome with 45, X/46, X, + mar chromosome karyotype were obtained, dual-color fluorescence in situ hybridization was applied to study the origin and morphology of the sSMC.

Results: In the 10 cases of Turner syndrome with 45, X/46, X, + mar karyotype, the sSMC of 7 cases was derived from X chromosome [sSMC(X)], the sSMC of 2 cases was derived from Y chromosome [sSMC(Y)] and the remaining 1 case was derived from the autosome.

[Cytogenetic analysis and phenotype location analysis on the karyotype of a ring chromosome 21 syndrome].

Objective: To search the forming cause and the correlation between the clinical phenotype and chromosome band by the cytogenetic analysis on a case of ring chromosome 21 syndrome.

Methods: Identification and location of 21 ring chromosome were performed with the G-banding, C-banding, N-banding, high-resolution banding and fluorescence in situ hybridization (FISH) techniques.

Results: It was found that the karyotypes of the patient's parents are normal.
