Effect of transfusion convalescent recovery plasma in patients with coronavirus disease 2019.

Objectives: To evaluate curative effects of coronavirus disease 2019 (COVID-19) patients by the transfusion of other convalescent plasma.

Methods: Retrospective analysis of the clinical data of 18 patients with severe and critical COVID-19, who were hospitalized in the ICU of Xianghu Branch of the First Affiliated Hospital of Nanchang University from February 1 to March 15, 2020. Patients were subdivided into an experimental group (=6, who had transfused the plasma) and an observation group (=12, who had no plasma transfusion).

The role of the Patient-Generated Subjective Global Assessment (PG-SGA) and biochemical markers in predicting anemia patients with cancer.

Purpose: The causes of anemia and the common side effects of cancer are multifactorial. Malnutrition is one of the alleged components of the aforementioned complications. This study planned to investigate the relationship among biochemical markers, Patient-Generated Subjective Global Assessment (PG-SGA), and anemia in cancer patients.

Chirality from achiral components: N,N'-bis(4-dimethylaminobenzyl)dodecane-1,12-diammonium in cucurbit[8]uril.

The long alkyl chain of N,N'-bis(4-dimethylaminobenzyl)dodecane-1,12-diamine (C(12)DA) adopts different chiral helical conformations, one left-handed and the other right-handed, when bound within the cavities of two distorted cucurbit[8]uril (Q[8]) units, as unequivocally established by X-ray crystallography.

2,2'-(Hexane-1,6-di-yl)diisoquinolinium tetra-chloridozincate(II).

The asymmetric unit of the title compound, (C(24)H(26)N(2))[ZnCl(4)], consists of two 2,2'-(hexane-1,6-di-yl)diisoquinolinium cations and two [ZnCl(4)](2-) complex anions. The [ZnCl(4)](2-) anions have a distorted tetra-hedral geometry. The dihedral angles between the isoquinoline rings of the two cations are nearly equal [16.

2,2'-(Butane-1,4-di-yl)diisoquinolinium tetra-chloridozincate(II).

The crystal of the title compound, (C(22)H(22)N(2))[ZnCl(4)], consists of 2,2'-(butane-1,4-di-yl)diisoquinolinium organic cations and [ZnCl(4)](2-) complex anions. The cation is located across a twofold axis and the Zn(II) atom of the anion is located on the other twofold axis. The centroid-centroid distance between parallel pyridine rings of neighboring mol-ecules is 3.

Methods for fabricating microarrays of motile bacteria.

Motile bacterial cell microarrays were fabricated by attaching Escherichia coli K-12 cells onto predesigned 16-mercaptohexadecanoic acid patterned microarrays, which were covalently functionalized with E. coli antibodies or poly-L-lysine. By utilizing 11-mercaptoundecyl-penta(ethylene glycol) or 11-mercapto-1-undecanol as passivating molecules, nonspecific binding of E.

Attachment of motile bacterial cells to prealigned holed microarrays.

Construction of biomotors is an exciting area of scientific research that holds great promise for the development of new technologies with broad potential applications in areas such as the energy industry and medicine. Herein, we demonstrate the fabrication of prealigned microarrays of motile Escherichia coli bacterial cells on SiOx substrates. To prepare these arrays, holed surfaces with a gold layer on the bottom of the holes were utilized.

Micro magnetic stir-bar mixer integrated with parylene microfluidic channels.

Previously, we reported a micro magnetic stir-bar mixer driven by an external rotating magnetic field and its rapid mixing performance in polydimethyl-siloxane (PDMS) channels. The PDMS piece with embedded fluid channels were manually aligned to a glass substrate and assembled. In this paper, we report the fabrication and testing results of a micro magnetic stir-bar monolithically integrated in parylene surface-micromachined channels with improved design features, including small tolerance of the stir-bar to channel wall (10 microm).
