Chronic bovine fasciolosis associated cholangiolithiasis: a case report

Ananda K. Javaregowda, Kavitha B. Rani
2016 Journal of Parasitic Diseases  
Cholangiolithiasis is a rare condition in animals wherein the choleliths are formed in the biliary tracts causing chronic inflammation. In the current study, choleliths which were firm and friable concretions of approximately 3-4 cm in diameter were found in the bile ducts of the liver of an adult cattle infected with Fasciola gigantica. Two such irregularly shaped concretions were encountered in the two biliary tracts leading to common bile duct in the liver. There were localized irregular

The histological investigation revealed chronic cholangitis with bile duct hyperplasia and cirrhosis. The co-existence of F. gigantica and choleliths indicated the physical pre-disposition for the formation of bile concretions in the bile duct which is not a common site for the occurrence of gall stones.

Susana M. B. Fraga, Maria S. T. Gonçalves, João C. V. P. Moura, Kavitha Rani
2004 European Journal of Organic Chemistry  
Keywords: Azo dyes / Non-fluorescent / Amino acid labeling / Peptide labeling Four carboxylic azo dyes are presented as new markers with spectroscopic absorption peaks ranging from 400 to 500 nm for amino acid and peptide labeling at their N-terminus. Labeling can also be performed at side chain residues as it is exemplified with lysine and serine. Introduction The use of dyes in chemistry, biology and medicine is continuously growing, with new applications in the diagnostic and treatment of

Although fluorometric methods are potentially much more sensitive than colorimetric methods, the use of non-fluorescent dyes for quantitative and qualitative analyses can offer some advantages. First, histochemical applications often require reliable, sensitive and stable detection of targets in complex samples that may have significant background from either natural sample´s auto fluorescence or fluorescence created during sample preparation. This problem is avoided by the use of non-fluorescent dyes. Second, the need of ultra violet radiation for excitation of fluorescent dyes, implies more expensive equipment than chromophoric methods. Examples of applications of non-fluorescent dyes include the use of amino acid N-derivatizing groups such as 4-[(N,N-dimethylaminophenyl)-4´-diazenyl]phenyl isothiocyanate for quantitative 3 analysis, [5, 6] 5-formyl-1H-pyrrole-2-carboxylic acid, which can be coloured on demand by treatment with hydrocinnamoyl chloride, [7, 8] and 4-[(N,N-dimethylaminophenyl)-4´diazenyl]benzenesulfonyl chloride (DABS-Cl) for amino acid analyses by HPLC, [9] [10] [11] capillary [12] and polyacrylamide gel [13, 14] electrophoresis. A method for staining proteins prior to polyacrylamide gel electrophoresis with Remazol Brilliant Blue R [15] and Drimarene Brilliant Blue, [16] two reactive dyes containing an ethyl sulfone and a difluorochloropyrimidyl group, respectively, was described. Non-fluorescent benzotriazole [17] and quinoline [18] azo dyes have been suggested for the study of dye-protein interactions and sequence analysis of genes by Resonance Raman spectroscopy. Another application of non-fluorescent dyes in peptide chemistry is the synthesis of coloured peptide libraries labeled with monocarboxylic blue anthraquinone and red azo dyes. [19, 20] Having this in mind and following our previous work with a non-fluorescent dye as a temporary marker in peptide chemistry, [21, 22] we decided to develop and test some new markers with spectroscopic absorption peaks ranging from 400 to 500 nm for amino acid and peptide labeling. Results and Discussion The new chromophores used (Scheme 1) were obtained by diazotation of 3-aminophenyl acetic acid, 2-amino-4-thiazoleacetic acid, 3-and 4-aminobenzoic acid and coupling of the resulting diazonium salt to N,N-dimethylaniline (1, 2) or to β-naphthol (3, 4) . [23] The carboxylic azo dyes (1-4) were bonded to α-amine group of various amino acid esters by coupling them with the aid of carbodiimide (DCC) assisted by hydroxybenzotriazole (HOBt) under standard conditions. After purification by chromatography (dry or flash) on silica gel followed by recrystallisation, the corresponding acetyl azo derivatives (5, 6) were obtained; the benzoyl azo derivatives (7, 8) were isolated by precipitation from the reaction mixture with water and recrystallised from acetone.

2021 Electronics  
In recent times, visible light communication is an emerging technology that supports high speed data communication for wireless communication systems. However, the performance of the visible light communication system is impaired by inter symbol interference, the time dispersive nature of the channel, and nonlinear features of the light emitting diode that significantly reduces the bit error rate performance. To address these problems, many environments offer a rich infrastructure of light

In this research paper, an effective routing protocol named the modified grasshopper optimization algorithm is proposed to reduce communication interruptions, and to provide alternative routes in the network without the need of previous topology knowledge. In this research paper, the proposed routing protocol is implemented and analyzed using the MATLAB environment. The experimental result showed that the proposed routing protocol adapts to dynamic changes in the communication networks, like obstacles and shadows. Hence, the proposed protocol achieved better performance in data transmission in terms of throughput, packet delivery ratio, end-to-end delay, and routing overhead. In addition, the performance is analyzed by varying the number of nodes like 50, 100, 250, and 500. From the experimental analysis, the proposed routing protocol achieved maximum of 16.69% and minimum of 2.20% improvement in packet delivery ratio, and minimized 0.80 milliseconds of end-to-end delay compared to the existing optimization algorithms.

Many Coronavirus disease 2019 (COVID-19) and post-COVID-19 patients experience muscle fatigues. Early detection of muscle fatigue and muscular paralysis helps in the diagnosis, prediction, and prevention of COVID-19 and post-COVID-19 patients. Nowadays, the biomedical and clinical domains widely used the electromyography (EMG) signal due to its ability to differentiate various neuromuscular diseases. In general, nerves or muscles and the spinal cord influence numerous neuromuscular disorders.
more » ... e clinical examination plays a major role in early finding and diagnosis of these diseases; this research study focused on the prediction of muscular paralysis using EMG signals. Machine learning-based diagnosis of the diseases has been widely used due to its efficiency and the hybrid feature extraction (FE) methods with deep learning classifier are used for the muscular paralysis disease prediction. The discrete wavelet transform (DWT) method is applied to decompose the EMG signal and reduce feature degradation. The proposed hybrid FE method consists of Yule-Walker, Burg's method, Renyi entropy, mean absolute value, min-max voltage FE, and other 17 conventional features for prediction of muscular paralysis disease. The hybrid FE method has the advantage of extract the relevant features from the signals and the Relief-F feature selection (FS) method is applied to select the optimal relevant feature for the deep learning classifier. The University of California, Irvine (UCI), EMG-Lower Limb Dataset is used to determine the performance of the proposed classifier. The evaluation shows that the proposed hybrid FE method achieved 88% of precision, while the existing neural network (NN) achieved 65% of precision and the support vector machine (SVM) achieved 35% of precision on whole EMG signal.

2018 Indian Journal of Animal Health  
Peste des petits ruminants (PPR) is a highly contagious and economically important disease of small ruminants associated with high morbidity and mortality. Outbreak investigation was carried out in the month of August 2015 in goat and sheep of Agasavalli village (Shivamogga district, Karnataka). A total of 341 goats and 60 sheep reared under semi-intensive system were investigated for morbidity, mortality and case fatality. Affected animals exhibited symptoms suggestive of PPR viz. high fever,

Representative samples (n=10) collected from ailing animals were analysed in the laboratory and post-mortem examination of dead animals were carried out. Lateral flow assay (serum) and polymerase chain reaction (PCR) of nasal swabs confirmed PPR virus infection as the cause of outbreak among sheep and goats. Morbidity, mortality and case fatality due to PPR during the outbreak were 76.5%, 24.9% and 32.6% in goats and 55.0%, 5.0% and 9.1% in sheep, respectively. Severity of infection was higher among young animals compared to adults. Keeping in view high morbidity and mortality of PPR infection in small ruminants, proper prophylactic vaccination of small ruminants is advocated for the management of disease.
