A reverse-transcription polymerase chain reaction (RT-PCR) protocol was developed for the detection of potato virus A (PVA) in dormant tubers. A 255-bp amplified product was produced using a primer pair from the P1 gene of the PVA genome. The 255-bp product was detected in nucleic acids from leaves, tubers, and purified virions and was specific to PVA as determined by Southern blot tests and detection by a PVA-specific probe. When presented with seven potato virus/strain nucleic acids and a viroid, singly and in mixed infections, the primer pair did not amplify any products. Its specificity to PVA was further demonstrated by RT-PCR detection of PVA from the known mixtures of PVA and potato virus Y samples. PVA was detected in foliage nucleic acids at a dilution of 1:1024–1:4096 and tuber nucleic acids at 1:256–1:1024. It was uniformly present in various parts of the potato tuber. PVA was detected in composite tuber samples containing a ratio of infected to healthy sap of 1:29 and was readily detected in tubers of several cultivars or breeding lines, in dormant as well as in sprouting tubers stored at 20–25°C for 4 months.

Oviduct Fluid

Hyaluronan (HA) has been related to fertilization and embryo development in the pig. Furthermore, HA is present in pig oviduct fluid and the lining epithelium, particularly of the pre-ovulatory sperm reservoir. Because the mechanisms that regulate HA synthesis have not yet been clarified, semiquantitative reverse transcription-polymerase chain reaction (RT-PCR) was conducted to assess the expression of mRNAs of two HA-synthesizing enzymes (has2 and has3) in the oviduct epithelium (uterotubal junction, isthmus, ampullary–isthmic junction and ampulla segments) of non-inseminated (control) and inseminated (treatment) sows at pre-, peri- and post-ovulatory oestrus. Only has3 mRNA was detected; it was present in all tubal segments of both control and treatment samples. The level of has3 expression did not vary significantly between non-inseminated and inseminated specimens, but there was a tendency (NS) for increased mean values during the peri- and post-ovulatory stages compared with pre-ovulation. It is concluded that has3 is expressed by the porcine endosalpinx epithelium and the levels of expression do not vary during the critical periods of sperm transport and fertilization, despite fluctuating levels of HA in the tubal fluid at corresponding periods.

AIM: Aim was to detect Brain and Acute Leukemia, Cytoplasmic (BAALC) and ETS-related gene (ERG) expression in patients with acute myeloid leukemia (AML) as well as to study their biologic and prognostic impact on the disease outcome and survival.PATIENTS AND METHODS: The current study was carried out on 44 patients with denovo acute myeloid leukemia, as well as 44 age and sex matched controls. The quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR) assay was performed for estimation of BAALC and ERG expression.RESULTS: The current study was carried out on 44 patients with denovo acute myeloid leukemia, as well as 44 age and sex matched controls. The quantitative real-time reverse transcription-polymerase chain reaction (RT-PCR) assay was performed for estimation of BAALC and ERG expression. BAALC was expressed in 36 (81.82%) of AML cases versus 10 (22.72%) of the control group which was highly statistically significant (P < 0.001). While ERG was positive in 39(88.64%) of cases and 8(18.18 %) of controls and that was also highly statistically significant (P < 0.001).CONCLUSION: Further researches still needed to clarify the role of BAALC and ERG in the pathogenesis of leukemia and their importance as targets for treatment of AML.

We report the first detection of Seoul hantavirus (SEOV) in a pet rat in Sweden. SEOV-specific antibodies were detected in the pet rat blood by focus reduction neutralising test (FRNT), and SEOV RNA in lung tissue was confirmed by reverse transcription-nested polymerase chain reaction (RT-PCR) followed by sequencing. The discovery follows the recent reports of SEOV infected pet rats, as well as associated human cases of severe haemorrhagic fever with renal syndrome (HFRS), in England and Wales.
