Zhiming Yang, Yunbo Wang, Xia Yuan, Ling Wang, Deli Wang
We studied the effect of dietary roughage species and their combinations on forage intake and growth rate of ewes during winter in a pastoral-farming area of northeast China. Twenty-five Northeast crossbred ewes (fine-wool sheep × Small-tailed Han sheep) were randomly selected and divided into five groups (G1, G2, G3, G4 and G5). During a 30 day feeding trial, each group of ewes were offered the same basal diet (composed of 0.36 kg chopped maize stalk (10 mm), 0.14 kg corn meal, 0.05 kg soybean meal and 1...

Placental restriction and insufficiency are associated with altered patterns of placental growth, morphology, substrate transport capacity, growth factor expression, and glucocorticoid exposure. We have used a pregnant sheep model in which the intrauterine environment has been perturbed by uterine carunclectomy (Cx). This procedure results in early restriction of placental growth and either the development of chronic fetal hypoxemia (PaO2≤17 mmHg) in late gestation or in compensatory placental growth and the maintenance of fetal normoxemia (PaO2>17 mmHg)...

This study tested whether feeding Rasa Aragonesa ewes certified organic feed, from 15 days before mating until lamb weaning, improved oocyte quality and in vitro maturation (IVM) and fertilization (IVF) performances of the offspring. In a second experiment, ovaries from ewe lambs that were bred on an organic farm and were of the same breed were compared with those from conventionally bred animals. The number (± standard error of the mean) of healthy oocytes per ewe lamb did not differ significantly between organic (12...

Three-dimensional (3D) tumor models are gaining traction in the research community given their capacity to mimic aspects of the tumor microenvironment absent in monolayer systems. In particular, the ability to spatiotemporally control cell placement within ex vivo 3D systems has enabled the study of tumor-stroma interactions. Furthermore, by regulating biomechanical stimuli, one can reveal how biophysical cues affect stromal cell phenotype and how their phenotype impacts tumor drug sensitivity. Both tumor architecture and shear force have profound effects on Ewing sarcoma (ES) cell behavior and are known to elicit ligand-mediated activation of the insulin-like growth factor-1 receptor (IGF-1R), thereby mediating resistance of ES cells to IGF-1R inhibitors...

The identification of genes regulating milk secretion by mammary glands is a key-step for exploiting changes in milk composition induced by different diet regimens. Linseed supplementation is a reliable feeding strategy to enhance polyunsaturated fatty acid content in milk fat from sheep, increasing milk quality and nutraceutical value. To investigate the molecular bases of diet induced differences in milk composition, we collected milk from dairy ewes at 90 day of lactation and after 3 weeks of diet supplementation with extruded linseed...

Ewing sarcoma/primitive neuroectodermal tumor (ES/PNET) is a tumor of small round cells arising in skeletal tissues. These tumors rarely arise in the stomach. We present a 31-year-old healthy female patient who was admitted to our surgical ward due to upper gastrointestinal hemorrhage. Upper endoscopy revealed a large ulcerated bleeding mass originating from the lesser curvature. Biopsy revealed tumor cell immunoreactivity positive for CD99, vimentin, and Ki67 (an index of proliferation). These findings were compatible with gastric ES/PNET...

Preterm births account for approximately 10% of births worldwide, with the majority (∼80%) being moderate preterm. Our aim was to determine the effects of moderate preterm birth on survival and long-term growth of male and female offspring using an ovine model of preterm birth that was preceded by a clinically relevant dose of corticosteroids. Ewes were induced to deliver preterm or at term; those assigned to deliver preterm were administered antenatal betamethasone (11.4 mg, 2 doses, 24 hours apart). The growth (body weight and body dimensions) of offspring was monitored to adulthood (62 weeks) when the animals were humanely killed for organ collection...

The CIC-DUX4 sarcoma is a subset of the undifferentiated small round cell sarcoma family, presently recognized as a new clinicopathological entity. It is a rare and highly aggressive tumor usually arising in the soft parts of the limbs and the trunk. Only a very few cases of primitive visceral CIC-DUX4 have been hitherto described. We report the case of a 29 year-old male patient with a primary CIC-DUX4 sarcoma of the kidney with lung metastasis. The outcome of the disease was rapidly unfavorable. Despite radical nephrectomy, the patient experienced an early local retroperitoneal recurrence associated with lung and liver metastases...

Although prognosis in patients with localized osteosarcoma has been dramatically improved by the introduction of multiple chemotherapy agents known as combination chemotherapy, there is growing concern about the development of secondary malignant neoplasms. We report the case of a 13-year-old girl in whom the diagnosis of Ewing sarcoma of bone localized on the shaft of left femur was made 2 years after successful treatment without radiotherapy for osteosarcoma of right proximal femur. EWS-FLI1 fusion gene was detected by reverse transcriptase-polymerase chain reaction...

The aim of the present study was to evaluate uterine blood flow (UBF) during the postpartum period in small ruminants. The study involved measures of UBF in 5 ewes and 5 goats during the first 4 weeks after parturition. Transrectal quantification of UBF was assessed by determining the diameter (DM), time averaged mean velocity (TAMEAN), blood flow volume (BFV), blood flow acceleration (ACCE) and pulsatility index (PI) in the uterine arteries ipsilateral to the previously gravid uterine horn(s) at Wk 20 of gestation and every 3days from the day of parturition (D 0) until Day 27 postpartum (D 27)...

INTRODUCTION: ERG expression has been described as a frequent event in prostate cancer indicating poor prognosis and promoting oncogenesis. It has also been demonstrated in Ewing's sarcoma, acute myeloid leukemia and acute T-lymphoblastic leukemia but could not be found in other epithelial tumors, Hodgkin's or Non-Hodgkin's lymphoma. We aimed to analyze ERG expression in multiple myeloma, following an index case of a patient with metastases of unknown origin in the spine strongly expressing ERG, which were thought to be of prostatic origin but turned out to be plasmacytic lesions...

Kazuo Kamemura
Of the FET (fused in sarcoma [FUS]/Ewing sarcoma protein [EWS]/TATA binding protein-associated factor 15 [TAF15]) family of heterogeneous nuclear ribonucleoprotein particle proteins, FUS and TAF15 are consistently and EWS variably found in inclusion bodies in neurodegenerative diseases such as frontotemporal lobar degeneration associated with FUS. It is speculated that dysregulation of FET proteins at the post-translational level is involved in their cytoplasmic deposition. Here, the O-linked β-N-acetylglucosamine (O-GlcNAc) glycosylation stoichiometry of the FET proteins was chemoenzymatically analyzed, and it was found that only EWS is dynamically glycosylated with a high stoichiometry in the neural cell lines tested and in mouse brain...

This study was performed to explain how the molecular processes governing the biosynthesis of gonadotropin-releasing hormone (GnRH) and GnRH receptor (GnRHR) in the hypothalamic-pituitary unit are reflected by luteinizing hormone (LH) secretion in sheep during anoestrous period and during luteal and follicular phases of the oestrous cycle. Using an enzyme-linked immunosorbent assay (ELISA), we analyzed the levels of GnRH and GnRHR in preoptic area (POA), anterior (AH) and ventromedial hypothalamus (VM), stalk-median eminence (SME), and GnRHR in the anterior pituitary gland (AP)...

INTRODUCTION AND HYPOTHESIS: Ewes develop pelvic organ prolapse (POP) and may be a suitable model for preclinical studies evaluating cell-based therapies for POP. The aim of this study was to establish a clinical score of vaginal weakness and to compare POP Quantification System (POP-Q) values in conscious nulliparous and parous ewes and determine whether ewes are a suitable POP model. METHODS: Ewes (n = 114) were examined while conscious, without sedation, and standing in a V conveyer by adapting the human POP-Q measurement...
