Ocular teratoid medulloepithelioma in a northern red-shouldered macaw: case report and literature review

A 4-mo-old northern red-shouldered macaw (Diopsittaca nobilis) was admitted to the veterinary hospital of the Arruda Câmara Zoo, in the State of Paraiba, Brazil, for investigation of an orbital mass. Given rapid progression and lack of response to treatment, the bird was euthanized, and an autopsy was performed. Histologically, the mass consisted of a retrobulbar invasive tumor characterized by tubular and rosette-like structures, with interspersed heteroplastic tissues, such as aggregates of neuroglial cells and islands of hyaline cartilage. The tumor was immunopositive for pancytokeratin, GFAP, NSE, and S100. These findings were compatible with an ocular teratoid medulloepithelioma, a neoplasm best described in humans but also reported rarely in young cockatiels and African Grey parrots.  相似文献   

Effects of CpG-B ODN on the protein expression profile of swine PBMC     

Nagarajan G  Kuo CC  Liang CM  Chen CM  Liang SM 《Veterinary research》2007,38(6):795-808

The CpG motif within bacterial DNA is a potent immuno-stimulatory moiety. Here, using a 2-D electrophoretic approach, we investigated the effect of synthetic oligodeoxynucleotide containing a B type CpG motif (CpG-B ODN) on the protein expression profile of swine peripheral blood mononuclear cells (PBMC). We found that several proteins including spondin 1, N-acetolactate alpha linked acidic dipeptidase; V kappa light chain, T cell receptor variable alpha chain, heat shock protein (Hsp) 60, Hsp70, KIAA0857 protein, and PNAS-146 were up-regulated in PBMC by CpG-B ODN stimulation. Further studies showed that CpG-B ODN-mediated Hsp60, Hsp70 and Hsp90 expressions were closely associated with the TLR9 signalling pathway. Pretreatment with inhibitors of Hsp70, Hsp90 and TLR9 all blocked the CpG-B ODN-mediated anti-apoptotic effect in swine PBMC. These results suggest that CpG-B ODN treatment of swine PBMC may enhance the expression of biologically active proteins, notably spondin 1, V kappa light chain, T cell receptor variable alpha chain and Hsps, which may play an important role in CpG-B ODN-mediated activation of immune responses and enhancement of swine PBMC survival.  相似文献

The effectiveness of consistent roguing in managing banana bunchy top disease in smallholder production in Africa

The removal of infected individuals is a common practice in the management of plant disease outbreaks. It minimizes the contact between healthy individuals and inoculum sources by reducing the infectious window of contaminated individuals. This requires early detection and consistent removal at landscape scale. Roguing of mats with symptoms of banana bunchy top disease (BBTD) in Cavendish banana production systems has been tested in Australia, using trained personnel, but has never been tested in smallholder systems. We studied the effectiveness of long-term consistent roguing in prolonging the productivity of banana orchards under smallholder farming systems in highland banana and plantain dominated production systems in Africa. We assessed the possibility of low-risk seed sourcing from the managed plots. Roguing reduced BBTD incidence to 2% in managed farmer fields and to 10% in experimental field plots, while a nonmanaged field eventually collapsed in the same period. With roguing, new infections decreased monthly compared to an exponential increase in a nonmanaged field. The emergence of new infections in both managed and nonmanaged farms followed a seasonal cycle. BBTD managed plots were a source of low-risk seed for replacing the rogued mats in the same fields, but perhaps not safe for use in nonendemic areas. We conclude that it is possible for smallholder farmers to recover and maintain banana productivity with rigorous roguing, which would entail early identification of symptoms and early removal of diseased mats. Studies are needed on the intensity of roguing under different disease and production conditions.  相似文献   

温州南部沿岸海域鱼类群落特征及其与环境因子的关系   总被引：3，自引：1，他引：3

根据2015年春季(5月)和秋季(9月)温州南部沿岸海域渔业资源调查数据,利用物种多样性指数、多元分析及其典范对应分析等方法,对该海域鱼类种类组成、多样性和群落与环境因子间的关系进行了分析。结果表明:温州南部沿岸海域共鉴定鱼类47种,隶属于9目27科41属,主要以暖水性和暖温性为主,鲈形目(Perciformes)种类最多,共26种;其次为鲱形目(Clupeiformes),共6种;再次为形目(Tetraodontiformes),共4种。春季,优势种依次为日本鳀(Engraulis japonicas)、镰鲳(Pampus echinogaster)、六丝矛尾虾虎鱼(Amblychaeturichthys hexanema)和棘头梅童鱼(Collichthys lucidus),其渔获量占总渔获量的49.3%;秋季,优势种为龙头鱼(Harpodon nehereus)、棘头梅童鱼和六指马鲅(Polynemus sextarius),占总渔获量的50.8%。日本鳀、蓝圆鲹(Decapterus maruadsi)、刺鲳(Psenopsis anomala)、龙头鱼、鳓(Ilisha elongata)和六指马鲅等是各季节各站位组的典型种及造成不同站位组间群落差异的主要分歧种。此外,组内的典型种一定程度上是组间的分歧种和群落的优势种。经Pearson分析,Margalef种类丰富度指数(D)和Shannon-Wiener多样性指数(H')与溶解氧呈极显著正相关,而与盐度和温度均呈显著正相关。通过典范对应分析(CCA)得出,影响鱼类群落的主要环境因子为酸碱度p H、水深和盐度。  相似文献   

Dopamine modulates the physiological response of the tiger shrimp Penaeus monodon     

Chin-Chyuan Chang  Zhi-Rong Wu  Cheng-Shou Chen  Ching-Ming Kuo  Winton Cheng   《Aquaculture (Amsterdam, Netherlands)》2007,270(1-4):333-342

Levels of glucose, lactate, pO₂, pCO₂, HCO₃⁻, TCO₂, Na⁺, K⁺, Cl⁻, protein, and oxyhemocyanin in the hemolymph and its osmolality and pH were measured when tiger shrimp, Penaeus monodon (13.5 ± 1.5 g body weight), were individually injected with saline or dopamine at 10^− 8, 10^− 7, or 10^− 6 mol shrimp^− 1. Results showed that hemolymph glucose, lactate, pCO₂, HCO₃⁻, and TCO₂ values increased from 2 to 4 h; hemolymph osmolality, Na⁺, and total protein had increased at 2 h; and hemolymph K⁺ decreased from 2 to 8 h after the dopamine injection. All physiological parameters returned to the control values 4–16 h after receiving dopamine. The dopamine injection also significantly decreased the oxyhemocyanin/protein ratio of P. monodon which occurred at 2 h, resulting from an elevation of hemolymph protein and a slight decrease of oxyhemocyanin. These results suggest that stress-inducing dopamine caused a transient period of modulation of energy metabolism, osmoregulation, respiration, and the acid–base balance in P. monodon in adapting to this environmental stress.  相似文献
