Measurements of serum anti-rotavirus IgA and/or SNA, are however,

Measurements of serum anti-rotavirus IgA and/or SNA, are however, considered as the standard for assessing immune response Small molecule library following rotavirus vaccination [8], [9], [19] and [7]. Immune responses to primary rotavirus infection are known to be largely homotypic, and SNA responses that occur after natural rotavirus infections in children are usually

serotype specific. Hence, the measurement of SNA response to each of the rotavirus serotype contained in PRV may provide a better measure of the protection than serum anti-rotavirus IgA [5]. In this study, the immune response to vaccination was assessed in approximately 360 infants whose blood was collected at baseline (pD1) and 14 days after the third vaccine dose (PD3). The observation that the anti-rotavirus IgA sero-response rate was similarly high in subjects in each of the African sites (Kenya, FK228 in vivo 73.8%; Ghana, 78.9%; Mali, 82.5%) indicates a consistent immune response to the vaccine among infants from the participating countries. Although the anti-rotavirus IgA sero-response rates were high and consistent across the region, they were approximately 10–15 percentage points lower than those observed in other regions of the world [5], [19], [20], [21], [22] and [23]. It is important to note that oral vaccines have traditionally been less immunogenic in developing world countries [3], [14] and [25]. The reason for this may be due to a combination

of the differences in host populations and associated health conditions, including malnutrition, maternal antibody, HIV infection and concomitant infections of the gut with Histone demethylase other enteropathogens [25]. Similarly, the observed PD3 serum anti-rotavirus IgA and SNA GMT levels were lower in the African subjects when compared to those of subjects in developed countries. The GMT (28.2

dilution units) of the serum anti-rotavirus IgA at PD3 of African subjects was 5- to 10-times lower than those measured 14 or 42 days after Dose 3 in subjects in developed countries [6], [18], [19], [20], [21], [22] and [23]. A consistent and similar pattern was observed when the data was evaluated by each African country. The significance of the reduced PD3 anti-rotavirus IgA GMT levels in African infants when compared to similar studies in developed countries is still not well understood because of the lack of an appropriate immune correlate of protection. This study offers some insights into this phenomenon. One reason that has been alluded to for the observed low immunogenicity may be the younger age of infants vaccinated in this study as compared to studies in developed countries [18] and [26]. However, post hoc analyses revealed that the rotavirus-specific immune responses for subjects who received vaccine dose 1 at less than 6 weeks of age was generally similar to those of subjects who were 6–12 weeks old although the numbers of subjects are low (data not shown).

Importantly, long-term propagation under high-density (as compare

Importantly, long-term propagation under high-density (as compared with sub-confluent) with extensive contact among cells have been shown to increase their saturation density, increase tumor incidence and decrease the latent period of tumor appearance after injection of cells into mice [43], [44] and [45]. The HD 10–87 VERO cells formed tumors in

NB and adult nude mice at p185 compared with p194 for LD 10–87 VERO cells in NB mice. Since doubling time for HD VERO cells was shorter (20 h) than LD VERO cells (26 h), it is conceivable that the faster proliferation rate, driven by selective pressures, may contribute to the enhanced tumor forming capacity of HD VERO cells. However, the association of signature miRNA over-expression appears to be related to the expression of the VERO cell tumorigenic phenotype rather than see more to the passage density NSC 683864 research buy or the reagents (tissue culture medium and serum) used for cell culture. This correlation between the passage at which the cells first expressed a detectable tumorigenic phenotype and the passage representing the peak expression levels of signature miRNAs illustrated that these miRNAs are potential biomarkers for the expression of the VERO cell tumorigenic phenotype. A comparison of the miRNA expression patterns between tumorigenic VERO cells and its corresponding tumor tissue may provide additional evidence supporting the specificity

of the miRNAs’ expression patterns to the expression of tumorigenic phenotype in VERO cells. In the present study, signature miRNAs were not monitored in tumor tissue formed by injection of tumorigenic VERO cells. However, a cell line established from a tumor formed from LD VERO cells at p250 had the same pattern of miRNA expression as the inoculated LD VERO cells [28]. Moreover, individual miRNAs such as miR-376a have been reported as highly expressed in different cancer tissues and cells when compared with the corresponding normal tissues and cells [28], [46], [47], [48], [49], [50], [51] and [52]. Thus, the concordance between the expression of signature SPTLC1 miRNAs and the miRNAs

previously identified in other tumor tissues suggests that these miRNAs are involved in the process of neoplastic development in VERO cells. Although individual miRNAs alone can be considered for use as a test for tumorigenic potential of VERO cells, the diverse and complex molecular events involved in the initiation and development of neoplasia argues against the use of individual miRNAs as tumor biomarkers. Thus, we propose that these six miRNAs be used as a panel of biomarkers for tumorigenic VERO cells, as the combination of these miRNAs may reflect various aspects of tumorigenesis and form a more complete indicator of the VERO cell tumorigenic phenotype. Understanding how these six miRNAs contribute to the neoplastic progression of VERO cells and their ability to form tumors would contribute to their usefulness as biomarkers for the expression of the VERO cell tumorigenic phenotype.

Three of four animals of Group B had significantly higher serum I

Three of four animals of Group B had significantly higher serum IgG and IgA titres following intravaginal administration of gp140 (IgG P = 0.05, IgA P = 0.039; paired t test) ( Fig. 2). In selleck compound contrast, none of the animals of Group C had increased serum antibody following intravaginal administration ( Fig. 3). As would be expected, titres of serum IgG and IgA were significantly higher at the time of intravaginal immunisation in animals of Group C that had received 3 intramuscular immunisations compared to those of Group B (IgG gmt: 18,197 versus 649, P < 0.001; IgA gmt: 1972 versus 173, P = 0.027; t-test). Results for mucosally detectable

antibody were more difficult to interpret given the variability seen at different sampling times and on some occasions between cervical and vaginal Gefitinib ic50 samples taken at the same time. All animals of Group B appeared to respond following intravaginal immunisation, including E49 that did not show a boost in serum antibody.

This animal was unusual in that serum IgA titres were similar to IgG titres and IgA titres were higher than IgG titres in cervical and vaginal samples. Interestingly, total IgA concentrations were not elevated in cervical or vaginal secretions from this animal (Table 2) and significant haemoglobin contamination was only seen at Day 126, when titres of anti-gp140 IgA in very the cervical sample had declined and were below the limit of detection in the vaginal sample. Mucosally-detected antibody responses were seen in all animals of Group C following intramuscular immunisation. In most instances antibodies appeared following the second immunisation, subsequently waned and recovered following a further intramuscular exposure. For logistical reasons it was not possible to obtain mucosal samples immediately before intravaginal

immunisation; however, antibodies were detected locally in all animals after the cycle of intravaginal immunisation but peak titres were not elevated. Overall, 3 intramuscular immunisations before intravaginal boosting conferred no advantage over a single intramuscular immunisation in terms of either the frequency or titre of antibody response detected in cervical and vaginal samples. Overall in Groups C and D both IgG and IgA anti-gp140 antibody titres were higher in cervical fluids than vaginal fluids, with median titres of IgG of 80 and 24 and of IgA of 103 and 54 in vaginal and cervical samples respectively (Fig. 4). This difference however only reached statistical significance for IgG. Comparison for individual animals showed cervical samples to contain higher titre antibody than vaginal samples on 76% and 85% of occasions tested for IgG and IgA respectively.

1 According to World Health Organization (WHO), medicinal plants

1 According to World Health Organization (WHO), medicinal plants are the best source to obtain the various drugs needed to combat various diseases selleck chemicals and it advocates the need for countries to venture into the different aspects of traditional medicine.2 Medicinal plants have been used to treat, prevent and cure

diseases of humans, plants and animals for as long as the history of man. This is because of the diversity of phytochemicals that are synthesized naturally as secondary metabolites by different plants and are available as a cache of medicines. Many of these phytochemicals are of immense benefit to man as therapeutic agents. In recent times there is resurgence in the buy LY2157299 popularity of herbs, both in the developing and developed countries alike, this attraction could be due to the numerous benefits of the standardized natural

products as compared to the largely synthetic orthodox medicines.3 The success of herbal products as a therapeutic agent is dependent upon how safe and active their constituents are when they are ingested. For maximum therapeutic benefits, it is important to take herbs in the form that best capture and preserves their active constituents while putting patients’ acceptability and adherence to medication into consideration. The oral route is the common route for administering herbal drugs required for systemic effects. However, most herbal medicines have unpleasant tastes which

make patients’ acceptance and adherence to medication a major problem.4 Phyllanthus amarus Schum. & Thonn. (Family Euphorbiaceae) is a small herb growing to less than two feet in height with small yellow flowers, leaves and fruits. It is a motile plant such that when the plant is picked, the feathery leaves fold in, completely closing themselves. The plant is well known for its Cell press medicinal properties. It is an important plant in Ayurvedic medicine and is widely used worldwide. 5 Phytochemical studies have shown the presence of many valuable compounds such as lignans, flavonoids, hydrolysable tannins (ellagitannins), polyphenols, triterpenes, sterols and alkaloids. The extracts and the compounds isolated from P. amarus show a wide spectrum of pharmacological activities including antiviral, antibacterial, antiplasmodial, antiinflammatory, antimalarial, antimicrobial, anticancer, antidiabetic, hypolipidemic, antioxidant, hepatoprotective, nephroprotective and diurectic properties. 6 Its use in cough, asthma and other bronchial infections has also been documented. 5 However, the extracts and traditional preparations of the plant have a bitter and astringent taste which is not acceptable by especially children and geriatrics. The aim of the present study therefore, is to develop pleasant tasting oral liquid preparations of the aqueous ethanolic extract of P.

Ticks were maintained under laboratory conditions for two years p

Ticks were maintained under laboratory conditions for two years prior to use in the experiments reported here. Cattle were

used to cycle the tick progeny. Tick stages requiring incubation were kept in the laboratory at 28 °C and 80% relative humidity. The Campo Grande cattle tick Ceritinib mw strain is susceptible to commercially available acaricides. The expressed sequence tag (EST) coding for RmLTI (GenBank ID: CK186726[21] and [24]) was optimized for P. pastoris codon usage, and synthesized by Epoch Biolabs, Inc. Codon optimization was done using Epoch Biolabs, Inc. proprietary software set at 15% cut off for codon efficiency. This RmLTI DNA fragment was cloned into pPICZαA, producing the pPICZαRmLTI construct. The recombinant plasmid codes for a His tag that is added to the N-terminus of the protein product. Previously described procedures were followed to produce rRmLTI in the P. pastoris expression system [25]. Alignment, similarity, and discordance comparisons based on bioinformatics techniques were conducted between predicted amino acid sequences for: rRmLTI, EST CK186726, BmTI-6 from ovarian cDNA (GenBank ID: P83606.2), and N-terminal amino acid sequence information for BmTI-A (GenBank ID: P83609), BmTI-D (GenBank find more ID: P83607), BmTI-2 (GenBank ID: P83603), and BmTI-3 (GenBank ID: P83604). ClustalW

from the BioEdit suite was used with Vector NTI® software (Invitrogen) as described previously to conduct the bioinformatics analyses [16]. The amino acid sequence from rRmLTI was submitted to protein function and superfamily analysis using the protein domains identifier software InterProScan [42]. Protein concentration in P. pastoris culture supernatant was quantified as described previously [25]. Proteins were precipitated with methanol and the precipitated proteins resuspended in denaturing binding buffer (8 M Urea, 20 mM sodium phosphate

pH 7.8, 500 mM NaCl). The rRmLTI was purified using a Ni2+ charged Ni-NTA (Qiagen, Hilden, Germany) affinity column with denaturing elution buffer (8 M Urea, 20 mM Sodium Phosphate pH 4.0, 500 mM NaCl) and the purification process monitored by 7.5% SDS-PAGE. Eluted fractions of high purity were pooled and dialyzed Phosphatidylinositol diacylglycerol-lyase against PBS. Animal care and use was conducted at EMBRAPA Beef Cattle according to institutional guidelines. Polyclonal serum against R. microplus larval extract or rRmLTI was produced using BALB/c mice as described previously [25]. The RmLTI vaccine was prepared with 500 μg of rRmLTI protein resuspended in 4 mL of 150-mM Tris–HCl at pH 7.4 and emulsified with 6 mL of Montanide ISA 61 VG (Seppic, Paris). Twelve female BALB/c mice were used, which were separated into two groups of six animals. One group received the rRmLTI formulation and the other the larval extract preparation. Each mouse within the respective group was immunized with 50 μg mL−1 dose−1 of rRmLTI, or 100 μg mL−1 dose−1 of larval extract. Three subcutaneous doses were applied at 21-day intervals.

Cultural characterization was done on ISP (International Streptom

Cultural characterization was done on ISP (International Streptomyces Project) Torin 1 nmr media; yeast extract – malt extract agar (ISP-2), oatmeal agar (ISP-3), glycerol asparagine agar (ISP-5), peptone yeast extract iron agar (ISP-6), inorganic salts starch agar (ISP-4), tyrosine agar (ISP-7) and nutrient agar at 28 °C. All media were obtained from Hi-Media, Mumbai. The growth of the

organism was studied at different temperatures and salt concentrations such as 22, 28, 37, 42 °C and 2, 4, 6, 8, 10% respectively. Utilization of different carbon and nitrogen sources such as d-glucose, d-galactose, d-fructose, d-mannitol, d-xylose, l-arabinose, l-rhamnose, l-raffinose, l-cysteine, l-histidine, l-tyrosine, d-alanine, l-leucine, l-phenylalanine and l-valine was studied. Chemotaxonomic studies were done by analyzing the cells for 2,6-diaminopimelic acid.9 16S rRNA studies were conducted and isolate MS02, was submitted in Microbial Type Culture Collection, IMTECH, Chandigarh, India. The preparation of total genomic DNA was conducted in accordance with the methods described by Sambrook et al7 PCR amplification of the 16S rRNA gene of the local Streptomyces strain MS02 was conducted

in accordance with the method described by Edwards et al 10 The sequence data were deposited in the GenBank database, under the accession number JF915304. The BLAST program (www.ncbi.nlm.nih.gov/blst) was employed in order to assess the degree of DNA similarity. Multiple sequence alignment and molecular phylogeny were evaluated using

BioEdit PARP inhibitor drugs software and the phylogenetic tree was displayed using the TREE Calpain VIEW program. 11 Spore suspension of Streptomyces isolate MS02, was prepared from the freshly grown culture on starch casein nitrate agar slant and inoculated into 100 ml starch casein nitrate broth (107 spores/ml of the medium) in 500 ml Erlenmeyer flask. The flask was incubated on rotary shaker (180 rpm) for 5 days at 28 °C. The culture was centrifuged at 8000 rpm for 20 min. The culture supernatant was used as a source of antifungal metabolite against C. albicans MTCC 183, as a target organism. Antifungal metabolite production was carried out in 100 ml starch casein nitrate broth (soluble starch – 10 g, Potassium phosphate dibasic – 2 g, Potassium nitrate – 2 g, Sodium chloride – 2 g, Casein –0.3 g, MgSO4. 7H2O – 0.05 g, CaCO3 – 0.02 g, FeSO4· 7H20 – 0.01 g, Distilled water – 1000 ml, pH – 7) in 500 ml Erlenmeyer flasks. The initial pH of the starch casein nitrate broth was adjusted to 4, 5, 6, 7, 8 and 9 separately with 0.1N NaOH/0.1N HCl. The pH 7.2 was used as control. All flasks were inoculated as mentioned above and incubated at 28 °C on rotary shaker at 180 rpm for 5 days.

01% gelatin (opsonization buffer) The bacteria treated with hype

01% gelatin (opsonization buffer). The bacteria treated with hyperimune or control mice sera were harvested and incubated with 4 × 105 peritoneal cells at 37 °C for 45 min with shaking (220 rpm). Ten-fold dilutions of the samples were performed and 10 μL aliquots of each dilution were cultured on blood agar plates. The count live colonies were performed as previously described [33]. After 20 min, slides of the M1 strain opsonophagocitic assay were prepared by cytospin, stained with Instant-Prov (Newprov, Brazil), subsequently analyzed by light microscopy using an Axion Vision Zeiss Imager A1 and photographed by Axion Vision software (Zeiss, Germany).

Statistical analysis was performed using Kruskal–Wallis test. Heart tissue was obtained from the lysate of a postmortem normal human mitral valve, separated selleck chemical by SDS–PAGE and blotted onto nitrocellulose membranes Transmembrane Transporters modulator [31] and [32]. The blots were blocked with Tris-buffered

saline containing 5% skim milk. The membrane was sequentially treated with a pool (n = 6) of BALB/c or Swiss immunized mice sera and anti-mouse IgG alkaline phosphatase and revealed with NBT-BCIP solution (Invitrogen, USA). We observed that anti-StreptInCor antibodies from the BALB/c mice sera pool were able to cross-recognize both the M5 and M1 proteins in total protein extracts from each strain (Fig. 1). The anti-StreptInCor antibodies from Swiss mice were able to neutralize the M1, M5, M12, M22 and M87 strains by cross-recognizing the M protein on the bacterial surface with a Median Fluorescence Intensity (MFI) 2 or 3 times greater than the MFI of control sera (Fig. 2). Anti-StreptInCor antibodies from BALB/c and Swiss mice were able to promote opsonophagocytosis and death of the M1, M5, M12, M22 and M87 strains (Fig. 3a and b, respectively). The amino acid sequences alignment of the M protein C-terminal region of the strains used in this study had, on average, 72% identity with the StreptInCor amino acid sequence (Fig. 3c). The M1, M6 and M12 strains had an additional block of 7 amino acids, while the M87 strain contained two fewer amino

acids than the StreptInCor sequence. M1 strain was killed in peritoneal cells by phagocytosis 20 min after the opsonization assay as observed by optical microscopy (Fig. 4a–d). No autoreactive 4-Aminobutyrate aminotransferase antibodies against human heart mitral valve protein extracts were observed (Fig. 5). The development of a vaccine against multiple S. pyogenes strains without causing autoimmunity will bring numerous benefits to human health. A vaccine would prevent streptococcal infections and sequelae and could be more effective and longer-lasting than the currently used treatment. In addition to have broad coverage against strains, a vaccine should promote the production of neutralizing and opsonophagocytic antibodies, which are the body’s major defense lines against extracellular microorganisms. In the 70 and 80s several models of anti S.

[Teratogenicity information is readily available from the DART database [450] and Motherisk, www.motherisk.org.] The adverse effects of atenolol PLX4032 in vivo on fetal growth have been particularly associated with use from early pregnancy [354],

[355], [356], [357] and [358]. Whether or when to replace ACE inhibitors, angiotensin-receptor blockers (ARBs), atenolol, or less commonly used antihypertensives pre-pregnancy or when pregnancy is diagnosed, and if so, with what is uncertain, but the following should be considered: If ACE inhibitors and ARBs are being given for renoprotection, no equivalent agent is available for use in pregnancy; however, much of ACE/ARB-related renoprotection is provided lowering BP, achievable by alternatives [7]. Normally, conception may take up to 12 months, Nutlin-3a supplier but women over 30 years have a higher incidence of subfertility. If an ACE inhibitor is discontinued

pre-pregnancy in a woman with renal disease, yet conception does not occur after 12 months and proteinuria is rising despite excellent BP control (i.e., <140/90 mmHg), it may be prudent to reinstate ACE inhibition, perform monthly pregnancy tests, and proceed with investigations of subfertility. A multidisciplinary approach towards comorbidities and/or cardiovascular risk factors is recommended. Although existing data are reassuring about use of statins in pregnancy, they should be discontinued pre-pregnancy or as soon as pregnancy is diagnosed until further data are available.

Information about safety with treatment at 240–336 weeks will come from the StAmP Trial (ISRCTN 23410175). For information on management of renal disease in pregnancy, see the update by Davison [451]. 1. MgSO4 is recommended for first-line treatment of eclampsia (I-A; High/Strong). For eclampsia, MgSO4 more than halves recurrent seizure rates compared with phenytoin [452], diazepam [453], or a lytic cocktail [454]. Also, MgSO4 (vs. diazepam) reduces maternal death; benzodiazepines should not be used for seizure termination. Loading is with MgSO4 4 g IV (or 5 g in South Africa) over 5 min, followed by infusion of 1 g/h. Treatment of any recurrent seizures is with another 2–4 g IV over 5 min. Serum Mg2+ levels are unnecessary, with women followed clinically for adverse Mg2+-related effects. In women unless with preeclampsia, MgSO4 (vs. placebo or no therapy) more than halves eclampsia occurrence (RR 0.41; 95% CI 0.29–0.58) [455] and [456]. Loading is with MgSO4 4 g IV over 10–15 min, followed by infusion of 1 g/h. The NNT (95% CI) to prevent one seizure is 50 (34–100) with severe preeclampsia and 100 (100–500) with non-severe preeclampsia. MgSO4 decreases abruption risk (RR 0.64; 95% CI 0.50–0.83; NNT 100 [50–1000]) but increases Caesarean delivery (RR 1.05; 95% CI 1.01–1.10) and side effects (RR 5.26; 95% CI 4.59– 6.03). MgSO4 (vs. phenytoin) reduces eclampsia (RR 0.08; 95% CI 0.01–0.60) but increases Caesarean delivery (RR 1.21; 95% CI 1.

The acute treatment decreased the Bcl-2 protein levels in the

prefrontal cortex (F(3–12) = 106.818; p < 0,001 Fig. 5A) and in the hippocampus (F(3–12) = 265,226; p < 0,001 Fig. 5A) with imipramine at the dose of 30 mg/kg and lamotrigine at the dose of 20 mg/kg, and also in the amygdala (F(3–12) = 87.304; p < 0.001 Fig. 5A) with all treatments, compared with saline. The chronic treatment decreased the Bcl-2 protein levels in the prefrontal cortex (F(3–12) = 310.093; p < 0.001 Fig. 5A), amygdala (F(3–12) = 238.818; p < 0.001

HEp-2 and DF1 cells were grown in Dulbecco’s modified Eagle mediu

HEp-2 and DF1 cells were grown in Dulbecco’s modified Eagle medium (DMEM) containing 10% fetal bovine serum (FBS) and maintained in DMEM with 5% FBS. MDBK cells were grown

in Eagle’s minimum essential medium (EMEM) containing 5% horse serum and maintained in EMEM with 2% horse serum. Recombinant and wild-type NDV strains were grown in 9-day-old specific-pathogen-free (SPF) embryonated chicken eggs. BHV-1 strain Cooper was obtained from ATCC and propagated in MDBK cells. The modified vaccinia virus strain Ankara expressing the T7 RNA polymerase was grown in primary chicken embryo fibroblast cells. The construction of plasmid pLaSota carrying the full-length antigenomic cDNA of the lentogenic NDV vaccine strain LaSota has been described

previously [30] and [31]. Two versions of the BHV-1 gD gene were constructed and inserted see more into the NDV genome. The genomic DNA of BHV-1 was isolated from purified BHV-1 using a standard protocol [32]. To make an insert encoding unmodified gD glycoprotein, the gD open reading frame (ORF) from BHV-1 genomic DNA was amplified by PCR using forward primer 5′-AGCTTTGTTTAAACTTAGAAAAAATACGGGTAGAACGCCACCatgcaagggccgacattggc-3′ and reverse primer 5′-AGCTTTGTTTAAACtcacccgggcagcgcgctgta-3′ that introduced PmeI sites (italicized), the NDV gene end and gene start transcriptional signals (underlined), the T intergenic nucleotide (boldface), an additional nucleotide in order to maintain the genome length as a multiple of six (italicized and bold), and a six-nucleotide Kozak sequence for efficient translation (bold, underlined). The BHV-1-specific Selleckchem Afatinib sequence is in small case. PCR was performed using 100 ng of pre-denatured viral DNA, 50 pmol of each primer, 2 × GC buffer I containing Mg2+, 200 μM dNTPs, 0.5 units of TaKaRa LA Taq™ polymerase (Takara Bio USA, Madison, WI). After amplification, the 1298 base pair product was digested with PmeI and PD184352 (CI-1040) cloned into pCR 2.1-TOPO vector (Invitrogen). The integrity of the gD gene was confirmed by sequence analysis. A second version of the gD gene was constructed in which the ectodomain of gD was fused to the transmembrane domain

and cytoplasmic tail (amino acids 497–553) of the NDV F protein by overlapping PCR. Briefly, the gD gene of BHV-1 was amplified by PCR using the forward primer described before and a reverse primer 5′-AGCTTTGTTTAAACggcgtcgggggccgcgggcgtagc-3′ (the PmeI site is italicized and the sequence specific to the BHV-1 gD gene at position 1057–1080 is in lowercase). To amplify the transmembrane domain and cytoplasmic tail sequences of NDV F gene, PCR was performed using forward primer 5′-gctacgcccgcggcccccgacgccAGCACATCTGCTCTCATTACCA-3′ (sequence specific to the BHV-1 gD gene overlap is in lower case and NDV F gene transmembrane-specific sequence is in uppercase) and a reverse primer 5′-agctttGTTTAAACTCACTTTTTGTAGTGGCTC-3′ (the PmeI site is italicized and NDV F gene cytoplasmic tail-specific sequence is in uppercase).
