The aim of the study was to scientifically evaluate the antimycobacterial activity of selected indigenous medicinal plants from the Limpopo Province used for the treatment of humans with symptoms of Mycobacterium tuberculosis. The leaves of five plant species (Apodytes dimidiata, Artemisia, Combretum hereroense, Lippia javanica, and Zanthoxylum capense) were collected from the Lowveld National ...

PLANT ROOTS WERE MECHANICALLY INJURED OR SUBJECTED TO NEMATODE PARASITISM TO TEST THE MODEL OF HOST DAMAGE BY TWO NEMATODE SPECIES: y = m' + (l - m')c'z(P)z(P) for y 1.0, where m' = m + (m - m) (1 - y)/[(1 - y) + (l - y)] and c' = (z(-T) + z(-T))/2. Damage functions for greenhouse-grown radish plants (cv. Cherry Belle) mechanically injured with small or large steel n...

In this chapter we describe an Agrobacterium tumefaciens transformation method of soybean that utilizes mature half seeds and regeneration from the cotyledonary node region. This method results in fertile transformed soybean plants and transgenic seed in approximately 9 months. Using mature half seeds as starting material has proven to be a reliable method that does not require additional wound...

Brucein D (BD), a major active quassinoid in Brucea javanica, has exhibited pronounced anticancer activities. However, the biologic mechanisms have not been fully explored. In this study, BD exhibited more potent cytotoxic effect on pancreatic cancer (PanCa) cell lines, while exerted weaker cytotoxic effects on GES-1 cells (non-tumorigenic). BD was shown to elicit apoptosis through inducing bot...

As a defense mechanism of the leaves of Rhus javanica (Anacardiaceae) against the aphid Melaphis chinensis (Aphididae) attack, tannic acid is rapidly accumulated and forms galls along the midrib of the leaves resulting in a unique natural medicine Gallae Rhois. Tannic acid was found to inhibit the oxidation of L-3,4-dihydroxyphenylalanine (L-DOPA) catalyzed by tyrosinase (EC 1.14.18.1) with an ...

Chitinolytic microflora may contribute to biological control of plant-parasitic nematodes by causing decreased egg viability through degradation of egg shells. Here, the influence of Lysobacter enzymogenes strain C3 on Caenorhabditis elegans, Heterodera schachtii, Meloidogyne javanica, Pratylenchus penetrans, and Aphelenchoides fragariae is described. Exposure of C. elegans to L. enzymogenes st...

The central component of a metal-responsive genetic switch, the MerR metalloregulatory protein, is one of the first examples of an mtracellular heavy metal receptor [l]. The merR gene product mediates the induction of the mercury resistance phenotype in bacteria [21, and resistant cells respond to subtoxic Hg(I1) levels (10 *6 -lo8 M) with transcriptional activation of the mer operon [31. Genet...

Purpose. To evaluate the efficacy of Brucea javanica oil emulsion injection (BJOEI) in patients with advanced non-small-cell lung cancer (NSCLC) during chemotherapy. Method. Electronic database of EMBASE and PubMed and the conference proceeding of ASCO, CNKI, CBMdisc, VIP, and Wanfang database were searched to select RCTs comparing BJOEI plus chemotherapy with chemotherapy alone in the treatmen...

Resistance to the root-knot nematodes Meloidogyne spp. would be a valuable attribute of lettuce Lactuca sativa L. cultivars grown in tropical regions. The looseleaf lettuce 'Grand Rapids' is resistant to both M. incognita and M. javanica. Resistance to M. incognita has a high heritability, under the control of a single gene locus, in which the 'Grand Rapids' allele, responsible for resistance (...
