Macroscopic assembly of 2D materials for energy storage and seawater desalination.

Since the discovery of graphene in 2004, two-dimensional (2D) materials have attracted widespread attention due to their excellent physical and chemical properties in the fields of energy, environment, catalysis, and optoelectronics. However, there are still many key problems in the process of practical application. To further promote the potential of 2D materials for practical applications, macroscopic assembly of 2D materials is crucial for the continued development of 2D materials, especially in the fields of energy storage and seawater desalination.

Quantitative and multiplexed detection for blood typing based on quantum dot-magnetic bead assay.

Background: Accurate and reliable blood grouping is essential for safe blood transfusion. However, conventional methods are qualitative and use only single-antigen detection. We overcame these limitations by developing a simple, quantitative, and multiplexed detection method for blood grouping using quantum dots (QDs) and magnetic beads.

Platelet activation is a key event in the pathogenesis of streptococcal infections.

Diverse Streptococcus species including Streptococcus Pneumoniae, Sanguis, Gordonii, Mitis and Mutans cause life-threatening conditions including pneumonia, bacteremia and meningitis. These diseases bear a high morbidity and mortality and for this reason, understanding the key events in the pathogenesis of these infections have a great significance in their prevention and/or treatment. Here, we describe as how the activation of the platelets and their affinity to bind to bacterial proteins act as early key events in the pathogenesis of Streptococcal infections.

Bone marrow stromal cells transduced with a thrombopoietin, interleukin-6, and interleukin-11 syncretic gene induce cord mononuclear cells to generate platelets in vitro.

Background: The induction of hematopoietic stem cells to produce mass numbers of platelets (PLTs) in vitro is an effective method to address a lack of PLTs and PLT transfusion resistance in the clinic. However, the design of a low-cost and sustainable culture system is currently problematic.

Study Design And Methods: Here, the thrombopoietin, interleukin (IL)-6, and IL-11 genes, three regulatory factors important for thrombopoiesis, were used to construct self-splicing fusion genes linked by foot and mouth disease (F2A) and Theiler's murine encephalitis (T2A) viruses.

HCV infection in voluntary donors and its influence on recruitment of donors in Chongqing area.

Blood donor recruitment models have changed from paid donors to employer-organized donors and to voluntary donors in China. Reports on the hepatitis C virus (HCV) infection among voluntary blood donors in China have been rarely found at present. The prevalence of anti-HCV and genotypes among the first-time voluntary blood donors was investigated in Chongqing area of China.

[Preliminary investigation on Paragonimus in Lvchun county of Yunnan province].

69 crabs were collected from Daxing, Gekui and Niukong townships of Lvchun county, Yunnan Province in 2006 and excysted metacercariae were only obtained from crabs of Niukong. The infection rate was 27.6% (8/29) with an average metacercaria number of 2.

[Analysis on mutations of GJB2 gene in Chinese population].

Objective: To determine the prevalence and types of GJB2 mutations and to investigate the genetic mechanism in Chinese autosomal recessive deafness.

Methods: The subjects were four Chinese pedigrees (39 individuals) and 50 normal adults. GJB2 was amplified by PCR.

Clinical assessment of preventing febrile nonhemolytic transfusion reaction by leukocyte-depleted blood transfusion.

The objective was designed to assess the clinical efficiency of preventing febrile nonhemolytic transfusion reactions (FNHTR) with transfusion of leukocyte-depleted RBC and platelet concentrates. One hundred patients with cirrhosis of liver, gastric ulcer and cancer were selected to receive RBC concentrates with leukocyte filtration. Another group of 50 patients with liver necrosis, gastric ulcer and cancer were selected to receive non-filtered RBC concentrates.
