Female Urethral Reconstruction
Female urethral strictures are rare; thus, the literature describing stricture management in women is sparse. Although urethral dilation continues to be performed at a high frequency in women despite lack of proven efficacy, this procedure is used for a variety of voiding complaints other than stricture. Hence, the long-term utility of dilation and urethrotomy for urethral stricture in women is unknown. This review describes the various urethroplasty techniques used in the management of female urethral stricture. Although grafts using a dorsal approach have been shown to be feasible in women, ventral flap techniques offer good long-term outcomes with minimal morbidity. Acute and delayed management of pelvic fracture–associated urethral distraction defects in women is also described. Unlike in men, immediate urethroplasty in women should be performed once the patient is hemodynamically stable
Post-imperialism, postcolonialism and beyond: towards a periodisation of cultural discourse about colonial legacies
Taking German history and culture as a starting point, this essay suggests a historical approach to reconceptualising different forms of literary engagement with colonial discourse, colonial legacies and (post-) colonial memory in the context of Comparative Postcolonial Studies. The deliberate blending of a historical, a conceptual and a political understanding of the ‘postcolonial’ in postcolonial scholarship raises problems of periodisation and historical terminology when, for example, anti-colonial discourse from the colonial period or colonialist discourse in Weimar Germany are labelled ‘postcolonial’. The colonial revisionism of Germany’s interwar period is more usefully classed as post-imperial, as are particular strands of retrospective engagement with colonial history and legacy in British, French and other European literatures and cultures after 1945. At the same time, some recent developments in Francophone, Anglophone and German literature, e.g. Afropolitan writing, move beyond defining features of postcolonial discourse and raise the question of the post-postcolonial
In silico exploration of Red Sea Bacillus genomes for natural product biosynthetic gene clusters
Background: The increasing spectrum of multidrug-resistant bacteria is a major global public health concern, necessitating discovery of novel antimicrobial agents. Here, members of the genus Bacillus are investigated as a potentially attractive source of novel antibiotics due to their broad spectrum of antimicrobial activities. We specifically focus on a computational analysis of the distinctive biosynthetic potential of Bacillus paralicheniformis strains isolated from the Red Sea, an ecosystem exposed to adverse, highly saline and hot conditions. Results: We report the complete circular and annotated genomes of two Red Sea strains, B. paralicheniformis Bac48 isolated from mangrove mud and B. paralicheniformis Bac84 isolated from microbial mat collected from Rabigh Harbor Lagoon in Saudi Arabia. Comparing the genomes of B. paralicheniformis Bac48 and B. paralicheniformis Bac84 with nine publicly available complete genomes of B. licheniformis and three genomes of B. paralicheniformis, revealed that all of the B. paralicheniformis strains in this study are more enriched in nonribosomal peptides (NRPs). We further report the first computationally identified trans-acyltransferase (trans-AT) nonribosomal peptide synthetase/polyketide synthase (PKS/ NRPS) cluster in strains of this species. Conclusions:B. paralicheniformis species have more genes associated with biosynthesis of antimicrobial bioactive compounds than other previously characterized species of B. licheniformis, which suggests that these species are better potential sources for novel antibiotics. Moreover, the genome of the Red Sea strain B. paralicheniformis Bac48 is more enriched in modular PKS genes compared to B. licheniformis strains and other B. paralicheniformis strains. This may be linked to adaptations that strains surviving in the Red Sea underwent to survive in the relatively hot and saline ecosystems

Measures Of Health And Production In Preweaned Kids In Pastoral Herds In Northern Kenya
Une étude a été conduite dans six sous-locations situées dans le Nord du Kenya pour évaluer les mesures sanitaires et la production des chevreaux non sevrés dans des
troupeaux pastoraux. On a conduit une évaluation auprès des pasteurs, afin de connaître
leur avis et aussi pour savoir dans quelle mesure les maladies constituent une contrainte
à la performance des chevreaux non sevrés, évaluation suivie d\'études transversales
et longitudinales pour une triangulation. Le taux moyen de morbidité était de 33% et il
était fortement associé aux sous-locations (
Effect of Balanites glabra canopy cover on grass production, organic matter and soil moisture in a southern Kenyan rangeland
A
study was undertaken in Kenya's southern savanna rangelands
to determine the seasonal effect of Balanites glabra
canopy cover on aboveground grass biomass, grass species composition,
soil organic matter and soil moisture content. The study was
conducted during the period June to December 1999 in order to
capture both the dry and wet season effects. The grass biomass
in the sub-canopy zone (2–4m from tree trunk) was found to be
significantly higher than in the mid-canopy (0–2m from tree
trunk) and open grassland zones (4–6m from tree trunk) during
the dry season. However, the difference between the sub-canopy
and the open grassland was not significant during the wet season,
implying that the role of a tree canopy in enhancing grass biomass
is greater during the dry than the wet season. Variations in
percent grass species composition from the mid-canopy to the
adjacent open grassland were observed, indicating that while
B. glabra canopy cover favours certain grass species,
other species find the micro-climatic conditions under the canopy
unfavourable. Soil organic matter in the mid-canopy zone was
significantly higher than in the sub-canopy and adjacent open
zones during both dry and wet season. Although the sub-canopy
zone exhibited significantly higher soil moisture content than
the mid-canopy and open grassland zones during the dry season,
the difference between the sub-canopy and the adjacent open
grassland during the wet season was not significant, suggesting
that the tree canopy influence on soil moisture is more pronounced
in the dry than the wet season. African Journal of Range & Forage Science 2003, 20(3): 259–26
