Porcine reproductive and respiratory syndrome virus (PRRSV) is the causal agent of a serious disease of swine. Here, we report the genome sequence of PRRSV strain HB-XL isolated from a pig farm with a clinical outbreak of porcine reproductive and respiratory syndrome. The genome is 15,323 bp long and has nine open reading frames (GenBank: KP162169). Comparative and phylogenetic analysis showed ...

A total of 250 dentists (53.6% men and 46.4% women), with a mean age of 35.1 ± 9.8 years, were submitted to serological tests for the diagnosis of hepatitis B (HB) – HBsAg, anti-HBs, anti-HBc, HBeAg, and anti-HBe – using a radioimmunoassay. One or more of these markers were detected in 78 individuals (31.2%) who were excluded from the group to be vaccinated. Of the 172 HB-susceptible individual...

hepatoblastoma (hb) is a rare tumor of infancy and childhood manifesting with hepatomegaly and abdominal distention. it is seen with increased frequency in association with congenital hemihypertrophy and renal anomalies. metastases to other organs, including the lungs, lymph nodes and even ovaries is well known. but cerebral metastasis of this tumor, especially in the absence of metastasis to o...

The level of Hb C in the erythrocytes of individuals with Hb C trait decreases significantly in the presence of coexisting alpha-thalassemia. This relationship may result from the higher affinity of beta A than beta C for limiting amounts of alpha-globin during hemoglobin assembly. This mechanism would predict that the beta A and beta C synthetic capacity in alpha-thalassemic individuals with H...

The efficacy of a noninvasive hemoglobin monitoring device (Astrin, Sysmex, Kobe, Japan) was evaluated for healthy volunteers and for patients with hematologic disorders. At the same time, the effects of WBC counts on noninvasive monitoring were studied by clinical evaluation and in ex vivo experiments. The hemoglobin levels determined by the device (Ast-Hb) and a conventional analyzer (T-Hb) w...

A minor hemoglobin (Hb) component with the electrophoretic properties of the 8-chain variant Hb A2' was encountered in two unrelated families of Russian-Jewish ancestry. This minor component, designated Hb NYU, was shown to result from the substitution of lysine for asparagine at 8'. We have confirmed studies of others that hemoglobin A2' isolated from the hemoglobin of some African subjects, r...

To increase blood safety Brazil introduced screening for anti-HBc among blood donors in 1993. There was a decrease in the hepatitis B virus (HB V) transmission, but this measure identified a great number ofHBsAg-negative, anti-HBc-positive donors. Surveillance policy determines that contacts of HBV carriers should be screened to HBV markers, but there is no recommendation about how to guide con...

Haemoglobin (Hb)-based oxygen carriers are under consideration as oxygen therapeutics. Their effect on apoptosis is critical, because the onset of pro-apoptotic pathways may lead to tissue damage. MP4OX, a polyethylene glycol-conjugated human Hb preserves the baseline level of neuron apoptosis with respect to sham. Here we develop a method for measuring Hb extravasation in brain. We exchange tr...

Isolated non-starch polysaccharides (NSP), especially isolated β-glucan, are reported to have prebiotic effects in pigs. However, little information is available on their possible functional properties when they are still present in the fibrous matrix of whole cereals. Hulless barleys (hB) are rich but variable sources of β-glucan. In order to evaluate their potential as functional feeds, an in...

Red cells from newborn lambs were separated into different age populations by centrifugation, and cells with fetal hemoglobin (Hb) were distinguished from those with adult Hb by an acid elution technique. Changes were followed during development in rates of K+ transport (active and passive), numbers of Na+/K+ pump sites per cell, cell volumes, and numbers of Lp and L1 antigen sites per cell. Th...
