<p>Leucocytozoonosis was found in three layer farms in chickens with suspected fatty liver or fatty liver hemorrhagic syndrome in Korea between 2009 and 2011. These layer chicken flocks showed both mortality and decreased egg production for one or two weeks when they were between 59 and 82 weeks old. At the necropsy, the most prominent gross lesions were found in the liver, which was enlarged, had a fragile texture, exhibited yellowish discolorations, and had various hemorrhagic lesions. Tissue reactions associated with megaloschizonts specific for Leucocytozoon caulleryi were prominent upon microscopic examination of the liver without significant lipidosis...

Many protein-based biotherapeutics are produced in cultured Chinese hamster ovary (CHO) cell lines. Recent reports have demonstrated that translation of recombinant mRNAs and global control of the translation machinery via mammalian target of rapamycin (mTOR) signalling are important determinants of the amount and quality of recombinant protein such cells can produce. mTOR complex 1 (mTORC1) is a master regulator of cell growth/division, ribosome biogenesis and protein synthesis, but the relationship between mTORC1 signalling, cell growth and proliferation and recombinant protein yields from mammalian cells, and whether this master regulating signalling pathway can be manipulated to enhance cell biomass and recombinant protein production (rPP) are not well explored...

Invasive trophoblast from Day-34 horse conceptuses survives in extra-uterine sites in allogeneic recipients that are immunologically naïve to donor major histocompatibility complex class I antigens. The ectopic trophoblast retains its in utero characteristics, including similar lifespan, physiologic effect of its secreted product (equine chorionic gonadotrophin) upon the recipient's ovaries, and induction of host immune responses. Immunologic memory has not been considered previously in this experimental system...

BACKGROUND: Classical Meigs' syndrome consists of the triad of an ovarian fibroma, ascites and pleural effusion. A characteristic of the syndrome is that the excess fluid is resorbed after surgical resection of the tumour. CASE DESCRIPTION: A 49-year-old woman was admitted to accident and emergency department in a neglected, cachectic and hypothermic condition. A CT scan revealed an ovarian tumour, ascites and a right-sided pleural effusion. The level of the tumour marker CA-125 was also greatly elevated...

During the last decade, analysis of anti-Müllerian hormone (AMH), highly conserved between mammalian species, has contributed to new information in reproductive endocrinology, due to clinically available diagnostic assays. AMH is produced solely in the gonads, in the Sertoli cells of testes and granulosa cells of the ovary, and thus offers possibilities to diagnose physiologic and pathologic conditions involving these organs. This article reviews indications for AMH analysis in cats and dogs, including diagnosing the presence of gonads, and granulosa or Sertoli cell tumours...

Cryopreservation of gametes is an important tool to preserve fertility, but for most species, including domestic dogs, data regarding ovarian tissue cryopreservation are limited. We aimed to evaluate the follicular and tissue viability and follicular growth after in vitro culture of domestic dog ovarian cortical slices cryopreserved by vitrification. Ovarian cortex was obtained from ten pairs of ovaries from domestic dogs using two methods (A and B), one for each ovary from the same bitch. At least four slices for each method were obtained from each ovary, one was processed for histology and the other three were vitrified...

BACKGROUND: A sarcoid reaction is a phenomenon characterized by histologically proven granulomatous lesions without evidence of sarcoidosis. This pathology is a benign tumor itself, but several reports have described sarcoid reactions accompanying malignant tumors. Sarcoid reactions occur in various cancers, such as skin, lung, ovary, stomach, and breast cancers. However, only a few published reports have described sarcoid reactions in patients with colorectal cancer. CASE PRESENTATION: A 76-year-old woman underwent laparoscopic sigmoidectomy for sigmoid colon cancer...

An accurate diagnosis of metastases to the ovary is essential for adequate patient management. The aim of this retrospective study was to characterize clinicopathological features of metastatic malignancies that presented as an ovarian mass and compare them with their corresponding primary tumors. We reviewed clinical files and histological material of 120 patients with metastases to the ovary, diagnosed in our center between 2000 and 2014. Metastases were diagnosed before (18 %), synchronously (33 %), or after (49 %) the primary tumor was identified; 25 % were single, 40 % were unilateral; 47 % were ≥13 cm...

The corticotropin-releasing hormone (CRH) signaling system is involved in numbers of stress-related physiological and pathological responses,including its inhibiting effects on estradiol (E2) synthesis and follicular development in the ovary. In addition, there are reports that microRNAs (miRNAs) can control the function of animal reproductive system. The aim of present study was to investigate the functions of miR-375 and the relationship between miR-375 and CRH signaling molecules in the porcine ovary. First, our common PCR results show that miR-375 and the CRH receptor 1 (CRHR1) are expressed in porcine ovary, whereas CRH receptor 2 (CRHR2) is not detected...

PAX2, a member of paired box family, is an essential transcription factor for the organ development in vertebrates including teleosts, yet no evidence has been shown for its involvement in reproduction. To study this, partial- and/or full-length cDNA of pax2 was isolated from the ovary of catfish, Clarias batrachus, along with its other Pax family members, pax1 and pax9 Tissue distribution and ontogeny expression analysis indicated the prevalence of pax2 but not pax1 and pax9 in ovary. Varied phase-wise expression during ovarian cycle and elevation of pax2 after human chorionic gonadotropin induction showed probable regulation by gonadotropins...

Bisphenol A diglycidyl ether (BADGE), a PPARγ2 antagonist, has been shown to inhibit marrow adipogenesis and promotes bone formation in intact animals. We investigated the impact of BADGE on a new and more clinically relevant physiological model, the ovariectomized (OVX) rat model. Forty female Wistar rats were divided into four treatment groups (n=10/group): sham+vehicle, sham+BADGE, OVX+vehicle and OVX+BADGE for 12 weeks. Postmortem analyses included MRI, micro-CT, serological test, histomorphometry, biomechanical tests, RT-PCR and western blot...

The cell-specific expression and intracellular distribution of the small heat protein Hsp27 was investigated in the ovaries and testes of the Mediterranean fruit fly, Ceratitis capitata (medfly), under both normal and heat shock conditions. For this study, a gfp-hsp27 strain was used to detect the chimeric protein by confocal microscopy. In unstressed ovaries, the protein was expressed throughout egg development in a stage and cell-specific pattern. In germarium, the protein was detected in the cytoplasm of the somatic cells in both unstressed and heat-shocked ovaries...
