A subset of human CD4 2 CD8 2 T cells that expresses an invariant V a 24-J a Q T cell receptor (TCR)a chain, paired predominantly with V b 11, has been identified. A series of these V a 24 V b 11 clones were shown to have TCRb CDR3 diversity and express the natural killer (NK) locus–encoded C-type lectins NKR-P1A, CD94, and CD69. However, in contrast to NK cells, they did not express killer inh...

In this study a factorial design was used to optimize process conditions produce spray-dried powder of dihydroartemisinin (DHA) with ?-cyclodextrin (?-CD). Predicted for maximum yield and minimum residual moisture were as follows: inlet temperature; 120 °C, aspirator setting; 100%, feed rate; 25%, molar ratio DHA:?-CD; 1:2. The higher percent inclusion obtained in the lower DHA:?-CD. DHA existe...

Phytoremediation is a technology for extracting or inactivating pollutants in soil. Echinodorus osiris (E. osiris) is a fast growing perennial wetland plant that is common in tropical and subtropical areas and has a high tolerance to cadmium (Cd). However, the absorption dynamics, subcellular distribution and accumulation of Cd by E. osiris had not been investigated. In this paper, hydroponic e...

The mined ecotype of Sedum alfredii Hance has been identified to be a zinc (Zn) hyperaccumulator native to China. In the present article, the characteristics of cadmium (Cd) uptake and accumulation were compared with hydroponic experiments between the mined and the nonmined ecotypes of Sedum alfredii Hance. The results indicate that the plants of the mined ecotype (ME) have higher tolerance of ...

BACKGROUND AND AIM It remains challenging to determine the inflammatory activity in Crohn's disease (CD) for lack of specific laboratory markers. Recent studies suggest that serum omentin-1 is associated with inflammatory response. We aimed to assess the potential of serum omentin-1 as a marker of disease activity in CD patients. METHODS Serum omentin-1 concentrations were determined by enzym...

The present study employed mass spectrometry (ICP-MS) to measure the internal cadmium concentrations (Cdint) in Caenorhabditis elegans to determine Cd uptake from a Cd-containing environment as well as Cd release under Cd-free conditions. To analyze the functional role of several ATP binding cassette (ABC) transporters (e.g., HMT-1 and MRP-1) and phytochelatin synthase (PCS), we compared wild-t...

We show that the canonical dimension cd Spin2n+1 of the spinor group Spin2n+1 has an inductive upper bound given by n + cd Spin2n−1. Using this bound, we determine the precise value of cd Spin n for all n ≤ 16 (previously known for n ≤ 10). We also obtain an upper bound for the canonical dimension of the semi-spinor group cd Spin∼ n in terms of cd Spin n−2. This bound determines cdSpin ∼ n for ...

The present study investigated the accumulation and depuration of two heavy metals Cd and Pb in the freshwater clam  (Corbicula fluminea) under laboratory conditions. Treated clams were exposed to single and combined treatments of Cd and Pb at the concentration of 5 mg L-1 and 10.5 mg L-1 for 10 days, respectively. The animals were then placed in metal free water for the following 5 days for de...
