We have studied the magnetization behavior and the magnetocaloric effect for the NiMn0.9Sb0.1 Heusler alloy. The sample was prepared by arc-melting in an argon atmosphere. For homogeneity of the samples, the ingot was melted several times. The temperature dependence of the magnetization of the sample was measured using a vibrating sample magnetometer in the magnetic field range up to 10 kOe. A large entropy change was observed from the H versus M curves associated with the ferromagnetic-paramagnetic transition. The maximum entropy change was 2.36 J/kg K at 697.5 K. Our results indicate that the present NiMn0.9Sb0.1 alloy is a good candidate as working material for a magnetic refrigerant.

Human and animal alveolar echinococcosis (AE) are important helminth infections endemic in wide areas of the Northern hemisphere. Monitoring Echinococcus multilocularis viability and spread using real-time fluorescent imaging in vivo provides a fast method to evaluate the load of parasite. Here, we generated a kind of fluorescent protoscolices in vivo imaging model and utilized this model to assess the activity against E. multilocularis protoscolices of metformin (Met). Results indicated that JC-1 tagged E. multilocularis can be reliably and confidently used to monitor protoscolices in vitro and in vivo. The availability of this transient in vivo fluorescent imaging of E. multilocularis protoscolices constitutes an important step toward the long term bio-imaging research of the AE-infected mouse models. In addition, this will be of great interest for further research on infection strategies and development of drugs and vaccines against E. multilocularis and other cestodes.
