A Human Case Report of Diphyllobothrium latum at Shanghai, China
H. Li,S.H. Chen,Y.N. Zhang,L. Ai,J.X. Chen
Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.3073.3075
Abstract: Fish tapeworm (Diphyllobothrium species) are endemic in many parts of the word, the commonest species being Diphyllobothrium latum. Human are the main definitive host of D. latum and the majority of individuals harbouring the parasite are asymptomatica. In this report, researchers describe a case of D. latum infection founded on routine detection of eggs in fecal. After the whole cestode gotten, PCR Molecular Method had been done for identification.
Shelf-life and Microbiological Profiler of Chicken Wing Products Following Sous vide Treatment
S.H. Wang,M.H. Chang,T.C. Chen
International Journal of Poultry Science , 2004,
Abstract: Chicken wings were vacuum-packaged and cooked (sous vide) at 75 and 90°C until the internal temperature reached 73.8°C was reached. The cooked samples were stored at 2 and 7°C, separately. The TBA values, aerobic plate count, aerobic and anaerobic plate counts and Warner-Bratzler (WB) shear force of the samples were evaluated weekly for 7 wk. The sous vide treatment chicken wings had lower TBA values, aerobic and anaerobic plate counts throughout the 7 wk of storage when compared with the control. The sous vide treatment did not affect the WB shear force of chicken wings. At 2°C, the sous vide cooked chicken wings had a shelf life of at least 7 wk. Results demonstrate that sous vide treatment was an effective method to prevent lipid oxidation during storage and enhance shelf life of chicken wing products.
Fu Zi Prevent Extreme Cold Stress in Broilers Through Anti-Oxidative Activity
X.Y. Chen,S.H. Jin,R.S. Jiang,Z.Y. Geng
Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.849.852
Abstract: Radix aconiti laterlis preparata (Fu Zi in Chinese), a Chinese traditional medicine has been widely used for Yang deficiency. Recent clinical studies have shown that Fu Zi could ameliorate stressed condition but the mechanisms underlying the anti-stress effect of Fu Zi remains unknown. In this study, researchers examined the effects of Fu Zi on the treatment of broilers exposed to Extreme Cold Stress (ECS). The levels of Nitric Oxide (NO) and creatine kinase in plasma were measured and Hsp70 mRNA expression in different tissues was analyzed. Broilers subjected to ECS exhibited increased NO content before 3 h and increased Hsp70 expression under a time and tissue-dependent manner. Biochemically, Fu Zi reversed ECS-induced increases in NO and Hsp70 mRNA and the results suggest that Fu Zi supplemented broilers kept an elevated plasma NO content through anti-oxidative activity during ECS.
On the Sackur-Tetrode equation in an expanding universe
Pereira, S.H.;
Revista mexicana de física E , 2011,
Abstract: in this work we investigate the thermodynamic properties satisfied by an expanding universe filled with a monoatomic ideal gas. we show that the equations for the energy density, entropy density and chemical potential remain the same of an ideal gas confined to a constant volume v. in particular the sackur-tetrode equation for the entropy of the ideal gas is also valid in the case of an expanding universe, provided that the constant value that represents the current entropy of the universe is appropriately chosen.

On the Sackur-Tetrode equation in an expanding universe
S.H. Pereira
Revista mexicana de física , 2011,
Abstract: En el presente trabajo investigamos las propriedades termodinámicas que son satisfechas por un universo en expansión, el cual es lleno por un gas ideal monoatómico. Se prueba que las ecuaciones para la densidad de la energía, la densidad de la entropía y el potencial químico son las mismas que las de un gas ideal, el cual se encuentra confinado en un volumen V. En particular, la ecuación de Sackur-Tetrode, para la entropía del gas ideal continua siendo válido en el caso de un universo en expansión, siempre que el valor constante que representa la entropía del universo actual sea escojido adecuadamente.

A New Species of Psammophilic Scorpion From Iran (Scorpions: Buthidae)
S.H. Navidpour
Journal of Biological Sciences , 2008,
Abstract: In order to study the psammophilic scorpions of sandy habitats of two provinces in western and south western Iran, some samplings were carried out by night catch (UV light) method during October 2007-March 2009. In total, 187 scorpions were collected. Vachoniolus iranus is a new species of Vachoniolus, that described from Khoozestan and Ilam provinces in South-western and Western of Iran. This is first record of genus Vachoniolus from Iran.
Effects of Tramadol on Liver and Renal Biochemistry and Histopathology in Dogs Undergoing Surgery under Pentobarbitone Anesthesia

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.1188.1194
Abstract: Effect of single and repeated doses of tramadol on hepatic and renal functions and on pentobarbitone anesthesia was evaluated in dogs. Twenty five dogs were randomly distributed into five equal groups viz groups I and II received 3 mg kg-1 of tramadol by subcutaneous and intravenous injections, respectively during premedication alone. Groups III and IV received similar doses of tramadol during premedication which was repeated 2 h after the initial dose thorough subcutaneous and intravenous injections, respectively. Group V served as negative control. Blood samples (2 mL) were taken at 0, 2 and 4 h after tramadol s administration while liver and kidney biopsies were taken before the surgery ended. Alanine Aminotransferase (ALT) and Aspartate Aminotransferase (AST) levels were significantly lowered in groups II-IV when compared to the group V at 4 h. Significant increase in AST was observed in groups I, III and V at 2 h and at 4 h in groups I and V. No significant change in kidney profile. Histopathological changes in the liver and kidney biopsies are mainly congestion, edema and cellular infiltration which occurred less frequently in groups III and IV. The volume of pentobarbitone was significantly lowered in groups III and IV. It is concluded that repeated administrations of tramadol at 3 mg kg-1, IV or SC is safe at a frequency of 2 h interval during surgery without causing irreversible hepatic and renal damage and reduced the required dose of pentobarbitone needed to maintain anaesthesia in healthy dogs.
TLC Determination of Marmesin, a Biologically Active Marker from Feronia Limonia L.  [PDF]
Mahendra Jain, Ashish Trivedi, S.H. Mishra
American Journal of Plant Sciences (AJPS) , 2010, DOI: 10.4236/ajps.2010.11002
Abstract: Feronia limonia Linn. (Rutaceae) have gained traditional therapeutic importance owing to their high essential oil and coumarins content. Marmesin, a furanocoumarin was identified by TLC and isolated by column chromatography and further purified by Preparative TLC. Presently, there is no appropriate TLC based method available for standardization of F. limonia. A simple, sensitive and accurate high performance thin layer chromatographic (HPTLC) method has been developed for the estimation of marmesin in the methanolic extract of stem bark of Feronia limonia. HPTLC was performed on precoated silica gel 60F254 aluminium plates (20 cm × 20 cm) with Chloroform: Methanol (9.5:0.5), as mobile phase. Quantitative evaluation of the plate was performed in the absorption-reflection mode at 338 nm. The calibration curve was linear in the concentration range of 20 – 100 ng spot–1. The method was validated for precision, repeatability and accuracy. The technique has been applied, for the first time, for the estimation of marmesin. The proposed method was found to be robust, precise, and accurate, it therefore holds potential for detection, monitoring and quantification of marmesin in Feronia limonia and its related formulation.
