dear Editor,Beige adipocytes,which increase energy expenditure by dissipating energy as heat,have gained attention as a therapeutic target for combating obesity.1 Adipocytes express many types of G-protein-coupled receptors(GPCRs),each of which has a unique preference for the Gs,Gi,Gq,and G12 *** the function of Gs-coupledβ-adrenergic receptors in beige adipocyte induction is well established,2 little is known about the function of G12-coupled GPCRs beyond its suppressive roles in white adipocyte maturation.3 In this study,we generated transgenic mice conditionally expressing a G12-coupled designer GPCR using a Cre-loxP system and investigated the potential effects of G12 signaling on adipocyte biology.

Objective To investigate the effects of extremely low frequency magnetic and electric fields （ELFEMFs） emitted from 380 kV transmission lines on some leukocyte differentiation antigens in dairy cows. Methods The study was carded out in 5 cows exposed to 1.98-3.28 μT of ELFEMFs and in 5 control cows exposed to 0.2-0.7 μT of ELFEMFs. Following haematological and immunologic parameters were measured in both groups： WBC, CD45R, CD6, CD4, CD8, CD21, and CD11B leukocyte antigen expression. Results Some of the haematological and immunologic parameters under investigation were similar in both groups. However, CD8 （T lymphocyte surface antigen） was higher in the exposed group （1.35 ±0.120 vs 0.50 ±0.14×10^3/mL）. Furthermore, the CD4/CD8 ratio （0.84 ±0.05 and 2.19±0.16 for exposed and not exposed cows respectively） and circadian rhythm were different between the two groups. Conclusion Exposure to ELFEMFs is responsible of the abnormal temporal variations and distribution of some haematological and immunological parameters in dairy cows.

In this paper a new type of passive neutron detector based on the already existing one, CR39, is described. Its operation was verified by three different neutron sources: an Americium-Beryllium (Am241-Be) source;a TRIGA type nuclear reactor;and a fast neutron reactor called TAPIRO. The obtained results, reported here, positively confirm its operation and the accountability of the new developed detecting technique.
