Monoparesis in association with feline pulmonary carcinoma: A literature review with 3 new cases     

Lucinda van Stee  Sarah Boston  Ameet Singh  Fiona Park  Danielle Richardson  Anthony Abrams-Ogg  Andrew Vince 《The Canadian veterinary journal. La revue veterinaire canadienne》2014,55(9):849-856

We describe 3 cases of cats that were presented with a sudden onset of monoparesis as a result of arterial thromboembolism without evidence of cardiovascular disease that were subsequently diagnosed with a primary pulmonary carcinoma. Arterial tumor thromboemboli due to pulmonary carcinoma should be considered as a differential diagnosis in cases of lameness or paresis in older cats. We theorize that large tumor emboli may obstruct peripheral arteries leading to acute monoparesis.  相似文献   

Methane emissions from river buffaloes fed on green fodders in relation to the nutriet intake and digestibility     

Sonali Prusty  Madhu Mohini  Shivlal Singh Kundu  Ajay Kumar  Chander Datt 《Tropical animal health and production》2014,46(1):65-70

Fifteen male Murrah buffalo calves (15–18 months, 227.98?±?4.44 kg body weight) were distributed randomly in to three equal groups and fed solely on either berseem (G₁), oats (G₂), or chicory fodder (G₃). A digestibility trial followed by methane measurement using SF₆ tracer technique was conducted. No significant difference was observed in nutrient intake; however, crude protein (CP) intake was lower in G₂ (0.35 kg) than G₁ (0.7) and in G₃ (0.71) and non-fibrous carbohydrates (NFC), and neutral detergent insoluble CP (NDICP) intake was significantly (p?<?0.05) higher in G₃ (1.54 and 0.31 kg) followed by G₂ (1.27 and 0.2 kg) and G₁ (1.06 and 0.18 kg). The digestible dry matter, organic matter, neutral detergent fiber, and ether extract intake was similar in all the groups, whereas the digestible CP and NFC intake was lower in G₂ compared to G₁ and G₃. Chicory- and berseem-fed groups emitted 12.2 and 5.2 % less methane than oats-fed group. However, no significant difference was observed in the absolute methane loss and methane loss as percentage of energy intake (p?>?0.05) among the groups. There was positive correlation between nutrient intake and total methane production. However, an inverse relationship was observed between total digestible carbohydrate intake and methane production (g/kg dry matter intake). The following regression equations were developed to estimate methane production: methane (g/kg BW) = 128.8553 + (167.7456 × dNDFI) + (216.32 × dCPI) ? (40.3313 × dNFCI) and methane (g/d) = ?1.7494 + (41.42 × NDFI) + (39.8686 × CPI) + (0.5197 × NFCI).  相似文献   

Expression of skin color genes in lymphocytes of Karan Fries cattle and seasonal relationship with tyrosinase and cortisol     

Uttarani Maibam  Sohan Vir Singh  Anil Kumar Singh  Suresh Kumar  Ramesh Chandra Upadhyay 《Tropical animal health and production》2014,46(7):1155-1160

To evaluate difference in the expression of skin color genes (melanocortin 1 receptor (MC1R) and premelanosome (PMEL)) in lymphocytes during winter and summer season and their correlation with tyrosinase enzyme and cortisol, ten Karan-Fries heifers were selected from National Dairy Research Institute (NDRI) cattle farm. Blood samples were collected from the animals during winter (THI?=?60) and summer (THI?=?83) season at weekly intervals. Relative MC1R and PMEL messenger RNA (mRNA) expression of Karan Fries cattle was found to be significantly (P?P?P?相似文献   

Economic losses due to cystic echinococcosis in India: Need for urgent action to control the disease     

Balbir B. Singh  Navneet K. Dhand  Sandeep Ghatak  Jatinder P.S. Gill 《Preventive veterinary medicine》2014

Cystic ehinococcosis (CE) caused by Echinococcus granulosus remains a neglected zoonotic disease despite its considerable human and animal health concerns. This is the first systematic analysis of the livestock and human related economic losses due to cystic echinococcosis in India.  相似文献   

Effect of bovine adenovirus 3 on mitochondria     

Sanjeev K Anand  Jaswant Singh  Amit Gaba  Suresh K Tikoo 《Veterinary research》2014,45(1):45

Viruses alter the structure and the function of mitochondria for survival. Electron microscopy analysis of the cells infected with bovine adenovirus 3 revealed extensive damage to the inner mitochondrial membrane characterized by dissolution of the cristae and amorphous appearance of mitochondrial matrix with little or no damage to the outer mitochondrial membrane. There were fewer cristae with altered morphology. Potential patches of protein synthesis machinary around mitochondria could be observed at 12 hours post infection (hpi). At 24 hpi, the multi vascular bodies were evident throughout the infected cell. ATP production, mitochondrial Ca²⁺ and mitochondrial membrane potential (MMP) peaked at 18 hpi but decreased significantly at 24 hpi. This decrease coincided with the increased production of superoxide (SO) and reactive oxygen species (ROS), at 24 hpi indicating acute oxidative stress in the cells and suggesting a complete failure of the cellular homeostatic machinary. The results reveal an intericate relationship between Ca²⁺ homeostasis, the ATP generation ability of cells, SO and ROS production, and regulation of MMP following infection by bovine adenovirus 3.  相似文献

Chiral symmetry breaking in sodium chlorate crystallizaton     

Kondepudi DK  Kaufman RJ  Singh N 《Science (New York, N.Y.)》1990,250(4983):975-976

Sodium chlorate (NaClO(3)) crystals are optically active although the molecules of the compound are not chiral. When crystallized from an aqueous solution while the solution is not stirred, statistically equal numbers of levo (L) and dextro (D) NaClO(3) crystals were found. When the solution was stirred, however, almost all of the NaClO(3) crystals (99.7 percent) in a particular sample had the same chirality, either levo or dextro. This result represents an experimental demonstration of chiral symmetry breaking or total spontaneous resolution on a macroscopic level brought about by autocatalysis and competition between L- and D-crystals.  相似文献

Variable x-ray and γ-ray emission is characteristic of the most extreme physical processes in the universe. We present multiwavelength observations of a unique γ-ray-selected transient detected by the Swift satellite, accompanied by bright emission across the electromagnetic spectrum, and whose properties are unlike any previously observed source. We pinpoint the event to the center of a small, star-forming galaxy at redshift z = 0.3534. Its high-energy emission has lasted much longer than any γ-ray burst, whereas its peak luminosity was ～100 times higher than bright active galactic nuclei. The association of the outburst with the center of its host galaxy suggests that this phenomenon has its origin in a rare mechanism involving the massive black hole in the nucleus of that galaxy.  相似文献   

Chromosomal aberrations induced in barley by LSD   总被引：1，自引：0，他引：1  

M P Singh  C S Kalia  H K Jain 《Science (New York, N.Y.)》1970,169(944):491-492

Seeds of hulled barley (Hordeum vulgare) were germinated and then treated with LSD. Preparations of squashed root tips stained with Feulgen revealed extensive chromosomal aberrations, most of which were chromosome breaks. Nearly half of the breaks occurred in the region of the primary constriction.  相似文献
