QUANTITATIVE DETERMINATION OF PHYTOCHEMICALS CONSTITUENTS OF JUSTICIA SPP. (IRUGEJE) SEED
No full textAbstract: Phytochemicals are non-nutritive plant chemicals that have protective or disease preventive properties. They are non-essential nutrients, meaning that they are not required by the human body for sustaining life. Justicia spp. (Irugege) is a spice used in the preparation of various dishes in the southern part of Nigeria. It grows in subtropical areas and is relatively drought resistant; it is believed to possess various nutritional properties. The aim of this work is to determine the quantitative phytochemical constituents of Justicia spp. Seed. The phytochemical constituent of the seed were carried out using gas chromatography flame ionization detector (GC-FID). Results revealed the presence of eleven phytoconstituents alkaloids (17.32/100g), terpenes (1.47mg/100g). tannins (4.59mg/100g), saponins (5.29mg/100g), anthocyanins (1.15mg/100g), phenols (119.40mg/100g), lignans (1.40mg/100g), glycosides (9.23mg/100g), phytosterols (45.52mg/100g), flavonoids (207.06mg/100g) and stilbenes (271.07mg/100g). Justicia spp., high in stilbenes, flavonoids, and phenols concentration could be used as a potent herbal antioxidant, cholesterol lowering, antimicrobial and anti-cancer agents.
Keywords: Phytochemical, Justicia Spp, Quantitative, Antioxidant and Constituents.

DETERMINATION OF HEAVY METALS IN SOILS UNDER PERIWINKLE SHELL DUMPSITES LOCATED IN CHOBA AND NKPOLU MARKETS IN PORT HARCOURT, NIGERIA
No full textAbstract: Soil samples under periwinkle sediments were collected from Choba and Nkpolu markets in Port Harcourt. Analysis was carried out on them using AAS to detect the presence of heavy metals. The results showed that the concentrations of these metals ranged from 0.548-1.024mg/kg for chromium; 0.174-0.263mg/kg for zinc; 0.439-0.643mg/kg for copper; 1.535-1.676mg/kg for iron; 0.323-0.499mg/kg for cadmium; 0.561-0.864mg/kg for manganese; 0.255-0.0468mg/kg for nickel and 0.302-0.535mg/kg for cobalt. Heavy metals are not easily excreted from shells but tend to bio-accumulate over a long period of time, especially during the rainy season. Heavy metal concentration above the permissible limit is harmful to soil, plant growth and causes severe health problems to humans. The use of waste shells in road and house construction is the best approach to reducing the effect of heavy metal pollution by shells.

SUITABILITY ASSESSMENT OF SOLID WASTE DISPOSAL SITES USING SOME PHYSICO-CHEMICAL AND GEO-MORPHOLOGICAL PROPERTIES OF SOILS
No full textAbstract: The soils of six locations (Rumuokoro, Eastern by-pass, Oyigbo, Bundu, Yenagoa and Bonny) indiscrimately used for disposal of wastes were evaluated for suitability classification using some physico-chemical and geo-morphological properties of the soils. The soils showed remarkable physico-chemical variability between the locations and also within the soil horizons. Yenagoa, Bonny and Bundu sites were most limited for use in landfilling of wastes and are more prone to both surface and ground water pollution due to their porosity, infiltration rate, pH, flooding, drainage and textural limitations. Rumuokoro site which was most suitable for landfilling of wastes was limited by pH, while Eastern by-pass site was limited by both the texture and porosity. This assessment shows that, no location possessed all the characteristics of waste landfilling. However, when a comparative study of the suitability of soils for waste landfilling was rated, the locations showed variable suitability in the following order: Rumuokoro > Eastern Bypass > Oyigbo > Bundu > Bonny > Yenagoa.

VERTICAL AND LATERAL DISTRIBUTION OF HEAVY METALS IN SOILS AFFECTED BY INDUSTRIAL AND MUNICIPAL WASTES IN PORT HARCOURT, NIGERIA
No full textAbstract: The distribution of some selected heavy metals (Lead, Mercury, Cadmium, Nickel, Chromium, and Iron) of five undisturbed soil profiles in Port Harcourt Metropolis affected by industrial and municipal wastes was assessed vertically and laterally, to ascertain the nature and extent of contamination, mobility particularly with respect to distance from the impact point, depth in the soil profile, and chemical form of metal in the soil. It was found that the concentration of the metals in the top-soil (0-5cm) at each site within impact point was very high. However, levels of these metals decreased with distance, with all metals reaching background levels at 100m away which show little relation to the metal loading at the surface horizon. Samples taken deeper in the profiles (30-60cm) nearly devoid of organic matter did not show elevated metal levels compared with the sites 100m away from the source. High concentration of heavy metals at the impact points of the study area could cause adverse effects on plant quality and yield, and also on human health.

Molecular Circuits of Resolution in Renal Disease
No full textInflammation is a common feature of renal pathology. Lipid mediators, such as lipoxins, resolvins, and protectins, can actively promote the resolution of inflammation by inhibiting polymorphonuclear cell infiltration to the site of inflammation, shifting the cytokine milieu from proinflammatory to proresolving and increasing the nonphlogistic phagocytosis of apoptotic cells by macrophages. Here we review the evidence for molecular circuits of resolution in renal disease
Mucosal immunization of calves with recombinant bovine adenovirus-3 coexpressing truncated form of bovine herpesvirus-1 gD and bovine IL-6
No full textPrevious studies have suggested an important role of the cytokine adjuvant IL-6 in the induction of mucosal immune responses in animals, including mice. Here, we report the in vivo ability of bovine adenovirus (BAdV)-3 expressing bovine (Bo) IL-6, to influence the systemic and mucosal immune responses against bovine herpesvirus (BHV)-1 gDt in calves. To co-express both antigen and cytokine, we first constructed a recombinant BAdV-3 expressing chimeric gDt.BoIL-6 protein (BAV326). Secondly, we constructed another recombinant BAdV-3 simultaneously expressing gDt and BoIL-6 using IRES containing a bicistronic cassette gDt-IRES.IL-6, (BAV327). Recombinant proteins expressed by BAV326 and BAV327 retained antigenicity (gDt) and biological activity (BoIL-6). Intranasal immunization of calves with recombinant BAV326, BAV327 or BAV308 (gDt alone) resulted in demonstrable levels of gDt-specific IgG responses in sera and IgA response in nasal secretions, in all animals. In addition, all calves developed complement-independent neutralizing antibody responses against BHV-1. However, no significant difference could be observed in the induction of systemic or mucosal immune response in animals immunized with recombinant BAV326 or BAV327 co-expressing BoIL-6. Moreover, there was no difference in the protection against BHV-1 challenge particularly in the amount of virus excretion in the nasal cavity in calves immunized with BAV326, BAV327 or BAV308. These data suggest that the BoIL-6 had no modulating effect on the induction of gDt specific mucosal and systemic immune responses in calves.Saskatchewan Agriculture Development FundAlberta Agriculture Research InstituteNatural Sciences and Engineering Research Council of Canad
Porcine circovirus 2 inclusion bodies in pulmonary and renal epithelial cells
No full textPorcine circovirus 2 (PCV2) is the cause of postweaning multisystemic wasting syndrome (PMWS). The most common lesions of PMWS are lymphohistiocytic to granulomatous lymphadenitis, interstitial pneumonia and interstitial nephritis, with intracytoplasmic amphophilic botryoid inclusion bodies in macrophages. In addition to these typical changes, intracytoplasmic botryoid Inclusion bodies were observed in bronchial, bronchial glandular, and renal tubular epithelium of several pigs from 4 different farms in Western and Eastern Canada. PCV2 inclusion bodies were demonstrated to be located in the cytoplasm of epithelial cells by immunohistochemical staining for PCV2 and cytokeratin antigens and by ultrastructural demonstration of viral particles in the inclusion bodies within renal tubular epithelium
Canine distemper virus-associated encephalitis in free-living lynx (Lynx canadensis) and bobcats (Lynx rufus) of Eastern Canada
No full textBetween 1993 and 1999, encephalitis caused by morbillivirus was diagnosed by immunohistochemistry and histology in six lynx (Lynx canadensis) and one bobcat (Lynx rufus) in the eastern Canadian provinces of New Brunswick and Nova Scotia. Five of the six cases in lynx occurred within an 11-mo period in 1996-97. A second bobcat with encephalitis caused by unidentified protozoa and a nematode larva also had immunohistochemical evidence of neurologic infection by morbillivirus. The virus was identified as canine distemper virus (CDV) by reverse transcriptase polymerase chain reaction and nucleotide sequencing in four of five animals from which frozen tissue samples were available, and it was isolated in cell culture from one of them. To our knowledge, this is the first report of disease caused by CDV in free-living felids in North America.JID: 0244160; ppublishSource type: Electronic(1
Resolution of inflammation: Therapeutic potential of pro-resolving lipids in Type 2 diabetes mellitus and associated renal complications
No full textThe role of inflammation in the pathogenesis of type 2 diabetes mellitus (T2DM) and its associated complications is increasingly recognized. The resolution of inflammation is actively regulated by endogenously produced lipid mediators such as lipoxins, resolvins, protectins and maresins. Here we review the potential role of these lipid mediators in diabetes-associated pathologies, specifically focusing on adipose inflammation and diabetic kidney disease, i.e. diabetic nephropathy (DN). DN is one of the major complications of T2DM and we propose that pro-resolving lipid mediators may have therapeutic potential in this context. Adipose inflammation is also an important component of T2DM-associated insulin resistance and altered adipokine secretion. Promoting the resolution of adipose inflammation would therefore likely be a beneficial therapeutic approach in T2DM
Conversational Structure in Electronic Mail Exchanges
No full textElectronic mail has become a widely used medium of communication in academia, government, and business. It is unique as a communication medium because it makes conversations across time, space, and organizational levels possible. The ability of electronic mail to forward a message allows for the creation of chains that preserve the entire conversation for each participant. This appears to be a new linguistic form in which the interactive features of spoken conversation are realized using electronically transmitted text.
The purpose of the present study was to determine the extent of the similarities and differences between spoken conversation and electronic mail exchanges. The research questions addressed were 1) What techniques that occur in spoken conversations also occur in electronic mail exchanges?, and 2) How are the techniques used in spoken conversations modified or different in electronic mail exchanges?
The data used in this study consisted of electronic mail text collected by the author in the course of her daily work in the data processing division of a large financial institution. The authors were computer technicians and middle managers with a wide diversity of educational backgrounds. Sixteen samples of message chains that contained at least three individual messages were selected for in-depth analysis. These samples were analyzed for conversational openings and closings, tum-taking mechanisms, adjacency pairs, and repetition.
Of the structural features studied, repetition was used in ways most similar to its uses in spoken conversation. The feature having the most differences from spoken interaction was the tum-taking system. In the electronic mail exchanges there was more variation in the sender\u27s selection of the next sender, including the option for multiple simultaneous replies. Openings and closings took many forms, some of them the same as in spoken conversation. Among the forms that differed were openings that resembled the salutation in a letter and closings that followed each individual message in a chain. Adjacency pairs such as questions and closings were paired as in spoken conversation, while openings, thanks, and apologies occurred as single utterances
