STRESS FRACTURES OF THE HUMERUS, RADIUS, AND TIBIA IN HORSES

The medical records, radiographic and nuclear scintigraphic findings of 26 racing horses with 27 stress fracture episodes of the humerus, radius, or tibia were reviewed. The purposes of this study were to describe the radiographic and/or scintigraphic features of stress fractures of the humerus, radius, or tibia, and to evaluate the signalment and history of horses in which stress fracture occurred. Stress fractures of the three long bones examined were primarily seen in 2-and 3-year-old male Thoroughbred horses; commonly, the onset of lameness was immediately following training gallops or racing. There were 13 humeral stress fracture episodes in 12 horses. Ten were in the proximal caudolateral cortex, and three were in the distal craniomedial cortex. Radial stress fractures were seen in three horses, all in the midshaft radius. Tibial stress fractures were diagnosed in 11 horses. They were located in the proximal lateral tibia in six horses, the distal caudolateral tibia in three horses, and the midshaft tibia in three horses. Fifteen stress fractures were diagnosed with radiographs alone, one was diagnosed with scintigraphy alone, nine were diagnosed with radiographs and scintigraphy, and, in two horses, radiographs were negative, but the scintigraphic findings were consistent with stress fracture.

五指山猪皮下脂肪组织lncRNA和mRNA的鉴定与分析

为了鉴定和分析五指山猪背部和腹部皮下脂肪组织中差异表达的长链非编码RNA(long noncoding RNA, lncRNA)和信使RNA(messenger RNA, mRNA),采用RNA-Seq和生物信息学方法对五指山猪皮下脂肪组织中的lncRNA和mRNA进行分析筛选,运用DESeq鉴定背部和腹部皮下脂肪组织中差异表达的lncRNA和mRNA,并对差异表达的lncRNA进行靶基因预测分析。结果显示:在五指山猪皮下脂肪组织中共鉴定出12 875个lncRNA,其中正义型10 155个、反义型278个、内含子型246个、基因间型2 196个;在背部与腹部皮下脂肪间,存在184个差异表达的mRNA,其中前十位分别是ZIC1、ZIC4、HAND2、CCBE1、RPH3A、ISM1、ANXA8、SLITRK4、DSG2、EVPL,存在45个差异表达的lncRNA,其中6个只在背部皮下脂肪中表达、18个只在腹部皮下脂肪中表达;获得差异表达lncRNA的靶基因共109个,包括顺式作用的靶基因和反式作用的靶基因。本试验为进一步研究lncRNA和mRNA调控猪皮下脂肪发育的分子机制提供科学依据。

Two Cases of Metastatic Parathyroid Carcinoma in Male C3H Mice Following Irradiation

White nodules were observed in the thyroid in two male C3H mice (at 99 and 122 weeks of age) exposed to fast neutrons at the age of 8 weeks. Histopathologically, in both cases, tumors were developed in the region corresponding to the parathyroid gland, and the tumor cells were arranged in a solid sheet or nest-like structures. Necrosis, cell debris and/or hemorrhage were sometimes seen in the center of the tumor structures. Tumor cells were small and uniform with scanty cytoplasm, cell margins were indistinct, and basally located tumor cells were aligned along the vascular stroma. Mitotic figures were frequently observed. Metastasis to the renal cortex was observed in both cases. These cases were diagnosed as parathyroid carcinoma. A parathyroid tumor is an extremely rare endocrine tumor in mice, regardless of whether the tumor is spontaneous or experimentally induced. These cases may have been induced by neutron-exposure; however, how radiation induces parathyroid carcinoma in mice is not clear.     

RADIOGRAPHIC AND ANGIOGRAPHIC EVALUATIONS OF FERRETS EXPERIMENTALLY INFECTED WITH DIROFILARIA IMMITIS

Five ferrets of each sex were each inoculated with 15 third-stage infective larvae of Dirofilaria immitis to study radiographic and angiographic changes in the cardiopulmonary system following heartworm infection; 5 additional ferrets of each sex served as noninfected controls. Prior to inoculation and every 8 weeks thereafter until 40 weeks, the infected and noninfected ferrets were radiographed; angiographic examinations were done prior to necropsy. At necropsy, the worms in the heart, lungs, and associated vessels were counted, and lung histosections were prepared and examined for changes. Radiographic changes were seen in the right side of the heart and associated vessels of infected ferrets as compared with the noninfected ferrets, but changes were less prominent than those seen in heartworm-infected dogs and cats. The changes were primarily an increase in the size of the right side of the heart, especially the right atrium. Radiographically, no changes could be visualized in the pulmonary vascular system. Worms in the enlarged cranial vena cava, azygous vein, and left caudal lobar pulmonary artery of infected animals were delineated by angiography. Histologically, no changes were seen in the pulmonary vascular tissues.
