Cereus peruvianus callus have a lot of alkaloids compounds and medicine extracted, which is important in medicine, medical and agricultural industries. The experiments were performed using Complete Randomized Design (CRD) and results were analyzed using one way ANOVA. MS medium supplemented with different concentrations of (2,4-D), kinetin and NAA were used. The study was carried out on Increas...

Nineteen species of gastro-intestinal nematodes were recovered from 10 Burchell's zebra. These include: Cyathostomum alveatum, C. montgomeryi and C. tetracanthum; Cylicocyclus auriculatus, C. gyalocephaloides, C. insigne and C. triramosus; Cylicodontophorus schürmanni and Cylicodontophorus n.sp., Cylicostephanus bidentatus, C. calicatus and C. minutus; Poteriostomum ratzii, Craterostomum acutic...

Habitat fragmentation reduces the extent and connectivity of suitable habitats, and can lead to changes in population genetic structure. Limited gene flow among isolated demes can result in increased genetic divergence among populations, and decreased genetic diversity within demes. We assessed patterns of genetic variation in the Caribbean boa Chilabothrus monensis (Epicrates monensis) using t...

The aim of this chapter is twofold. First, to outline how recent developments in cooperation theory are so similar to the communication network concept (McGregor, 1993) that a unified terminology would be useful to facilitate exchange of ideas. Second, we argue that the communication network concept provides an evolutionary framework to predict the widespread occurrence of phenomena that until ...

A novel marine bacterium, strain JCS350(T), was isolated from marine sediment samples collected from a cold-seep area. The 16S rRNA gene sequence of the isolate showed high similarity to that of Erythrobacter luteolus SW-109(T) (95.9 % sequence similarity). Lower 16S rRNA gene sequence similarities were shown to other members of the genus Erythrobacter (94.6-95.4 %) and members of the genus Por...

TEMAS is an apperception test depicting Hispanic and Black characters (minority version) or White characters (non-minority version) interacting in urban settings and expressing culturally oriented themes. It is scored for cognitive, affective, and personality functioning. The normative profiles, reliability, and criterion-rele'ed validity of TEMAS were compared for school and clinical children ...

There are 23 species of Myrsidea recognized from passerine thraupid hosts. Five new species parasitic on members of this avian family are described. They and their type hosts are Myrsidea rozsai ex the Thick-billed Euphonia, Euphonia laniirostris d'Orbigny & Lafresnaye, M. cruickshanki ex the Carmiol's Tanager, Chlorothraupis carmioli (Lawrence), M. patersoni ex the Grey-headed Tanager, Eucomet...

The aim of this study was to isolate bacteria with antimicrobial activities from the marine sponges Aplysina aerophoba and Aplysina cavernicola. The obtained 27 isolates could be subdivided into eight phylogenetically different clusters based on comparative sequence analysis of their 16S rDNA genes. The sponge isolates were affiliated with the low (Bacillus) and high G+C Gram-positive bacteria ...

Despite recent successes against large banking malware botnets such as Gameover Zeus and Shylock, banking malware continues to be a huge threat as new families such as Dyreza, Vawtrak and Dridex have occupied the vacant space in the market. Not only has the malware itself matured but we have also seen the ecosystem and market model used by the malware authors evolve, as they gain in professiona...
