Abstract
Past studies suggested that during early lactation and the transition period, higher plasma growth hormone (GH) levels in subclinical ketosis (SCK) might involve the initiation of body adipose tissues mobilization, resulting in metabolic disorders in ruminants particularly hyperketonemia. The upregulated GH mRNA expression in adipose tissue may take part in the adipolysis process in SCK-affected cows that paves a way for study further. This study aimed to characterize the plasma levels of GH, β-hydroxybutyrate acid (BHBA) and non-esterified fatty acid (NEFA) and glucose (GLu) in ketotic cows and healthy control (CON) cows; to measure the liver function test (LFT) indices in ketotic and healthy CON cows, and finally the quantitative real-time PCR (qRT-PCR) assay of candidate genes expressed in adipose tissues of ketotic and healthy CON cows during 0 to 7 week postpartum. Three experiments were conducted. Experiment-1 involved 21 Holstein cows weighing 500–600 kg with 2–5 parities. Results showed that GH, BHBA, and NEFA levels in ketotic cows were significantly higher and the GLu level significantly lower. Pearson's correlation analysis revealed a significant positive correlation of GH with BHBA, NEFA, and GLu in ketotic and healthy CON cows. In experiment-2, dynamic monitoring of LFT indices namely, alanine aminotransferase (ALT), aspartate aminotransferase (AST), γ-glutamyl transpeptidase (GGT), total bilirubin (TBIL), direct bilirubin (DBIL), total protein (TP), albumin (ALB), globulin (GLOB) and albumin/globulin (A/G) were examined. The TBIL, DBIL, and GGT indices were significantly higher in ketotic cows and TP was significantly lower. In experiment-3, mRNA expression levels of GHR and peroxisome-proliferator-activated receptor alpha (PPARα) genes in adipose tissue were significantly upregulated in ketotic cows. However, the mRNA expression of insulin-like growth factor-I (IGF-1), insulin-like growth factor-I receptor (IGF-1R), and sterol regulatory element-binding protein-1c (SREBP-1c) genes in adipose tissue were downregulated in ketotic cows. Our study concluded that during postpartum, higher plasma GH levels in SCK cows might involve the initiation of body adipose tissue mobilization, resulting in hyperketonemia.

Abstract
Enzootic nasal adenocarcinoma is a contagious respiratory disease in goats that is caused by the enzootic nasal tumor virus 2 (ENTV-2). In order to increase the number of available detection methods for ENTV-2, we developed a SYBR Green real-time polymerase chain reaction (SGrPCR) assay that targets the gag gene of ENTV-2. The low limit of detection of the assay was 3.68 × 101 copies/μL, a hundredfold more sensitive than conventional PCR. The melt curve showed a single sharp melt peak at 83°C, which indicated that there was no non-specific amplification or primer dimer formation. The intra-assay and inter-assay coefficients of variation were 1.58% and 1.82%, respectively. There was no cross-reactivity with closely related goat viruses (i.e., orf virus, peste des petits ruminants virus, goatpox virus, foot-and-mouth disease virus) and endogenous retroviruses. In conclusion, the SGrPCR assay is specific for the gag gene of ENTV-2 and provides a rapid and sensitive approach for detecting ENTV-2 in clinical samples.

Abstract
Fourier transform (FT)-Raman spectroscopy has been used extensively for the characterisation of polymers, especially polymers containing functional groups. New macromers with unsaturation have been synthesised using a living anionic polymerisation process. The reactions of living polystyryllithium with butadiene, followed by the capping reaction with mono or tri-functional chlorosilane norbornene were investigated. Characterisations by NMR and GPC have confirmed the formation of these macromers, but FT-Raman spectroscopy has revealed interesting information related to the isomerisation of the butadiene spacer in the polymer backbone.

Abstract
Infections due to hepatitis A (HAV), hepatitis B (HBV), hepatitis C (HCV) and hepatitis E (HEV) viruses are the major causes of hepatitis and are associated with significant morbidity and mortality in developing countries like Bangladesh. The present study was carried out to determine the prevalence of HBsAg, anti-HCV antibody, anti-HAV antibody and anti-HEV antibody in patients suspected of having infection by HBV, HCV, HAV and HEV, respectively. Antibody to HAV was detected in 39% of subjects investigated. HBsAg was identified in 19% of subjects. Antibody to HCV and HEV was detected in 13% and 53% subjects, respectively. Infection with HAV was very high among children < or = 6 years of age (100%). On the contrary, exposure to HEV was higher in adult persons > or => 30 years of age (52%) compared to that in children < or = 6 years of age who had 0% incidence. Our study clearly indicates a high prevalence of those viruses, particularly of enterically transmitted HAV and HEV in Bangladesh, which appeared to be a serious health problem in this developing country. Control measures should be taken on an urgent basis to prevent the spread of infections by these viruses.
