Production of Sc and Sc from natural CaF material using an FN Tandem accelerator.

The radioisotopes of Sc and Sc are promising in the field of theranostics for their role as β emitters in theranostic pairs with Sc. Production of these isotopes through various nuclear reactions using either cyclotrons or linear accelerators is of particular interest and previous studies have provided results using accelerated beams of protons, deuterons, and alpha particles. A novel production technique, using an ion source cathode packed with natural calcium fluoride material and irradiated with a He beam, was tested at the Nuclear Science Laboratory at the University of Notre Dame in order to initially study the production of Ca.

A Comparison of Buffered Tricaine Methanesulfonate (MS-222) and Isoeugenol Anesthesia for Caudal Fin Clipping in Zebrafish ().

The purpose of this study was to compare the safety and efficacy of buffered tricaine methanesulfonate (MS-222) and isoeugenol for the anesthesia of zebrafish undergoing caudal fin clipping. Eighty 9 mo (AB strain) zebrafish were allocated to one of 2 equal groups: buffered MS-222 (168 mg/L, = 40) or isoeugenol (20 mg/L, = 40). The time to induction of anesthesia was significantly shorter in the isoeugenol group (141 ± 70 s) than in the MS-222 group (207 ± 103 s).

Cryptosporidium homai n. sp. (Apicomplexa: Cryptosporidiiae) from the guinea pig (Cavia porcellus).

The morphological, biological, and molecular characterisation of a new Cryptosporidium species from the guinea pig (Cavia porcellus) are described, and the species name Cryptosporidium homai n. sp. is proposed.

The buddy system: A randomized controlled experiment of the benefits and costs of dieting in pairs.

A total of 67 pairs of female roommates were randomized into a diet condition: (1) both ate normally; (2) one dieted, the other ate normally; and (3) both dieted. Adherence, weight loss, anxiety, depression, disordered eating symptoms, and stress were measured. Dieters lost more weight than non-dieters, but average loss was <1 pound.

Mortality associated with using medetomidine and ketamine for general anesthesia in pregnant and nonpregnant Wistar rats.

Medetomidine and ketamine are injectable drugs that can be used in combination to induce general anesthesia in rats. After noticing a high incidence of morbidity and mortality in pregnant Wistar rats given medetomidine and ketamine for anesthesia, the authors further investigated the effects of this combination of anesthetic drugs in both pregnant and nonpregnant Wistar rats. The time to recumbency and the duration of general anesthesia were similar between pregnant and nonpregnant rats.

Development, evaluation, and peer verification of a rapid real-time PCR method for the detection of animal material.

Four real-time PCR assays that can be used with U.S.- and European Union-rendered materials to detect three ruminant species (bovine, caprine, and ovine) and a select set of avians (chicken, goose, and turkey) were developed.
