background: there is a renewed interest in job satisfaction among healthcare workers including nurses in africa and the west african sub-region due to the perception that global shifts in the internal structures and employment practices are inducing changes in the ties that bind employees to their job. therefore, it is necessary to examine various studies in order to establish an empirical base...

Many mammalian species are adapted to living in burrows for most of their lives. Inhabiting such thermally stable environments may influence the variation on thermogenic capacity, particularly non-shivering thermogenesis (NST). African mole-rats (Bathyergidae) subterranean rodents occurring fynbos, grassland and wooded savannas across sub-Saharan Africa that vary complexity social systems, rang...

Age-related changes in children's associations of economic resources and race were investigated. The sample (N = 308) included 5-6 year-olds (n = 153, M = 6.01 years, SD = 0.33 years) and 10-11 year-olds (n = 155, M = 11.12 years, SD = 0.59 years) of African-American (n = 93), European-American (n = 92), Latino (n = 62), Asian-American (n = 23), and multi-racial or multi-ethnic (n = 26) backgro...

We present a comprehensive assessment of genomic diversity in the African-American population by studying three genotyped cohorts comprising 3,726 African-Americans from across the United States that provide a representative description of the population across all US states and socioeconomic status. An estimated 82.1% of ancestors to African-Americans lived in Africa prior to the advent of tra...

"Rat trading"—"front-running" in the U.S.—is a typical criminal behaviour securities market. To better reduce emergence of "rat trading" behaviour, this paper expounds on essence through theoretical analysis. It highlights defects current management. Because existing flaws, puts forward solutions for reference relevant personnel.

BACKGROUND RNA activation (RNAa) is a newly discovered mechanism of gene activation triggered by small double-stranded RNAs termed 'small activating RNAs' (saRNAs). Thus far, RNAa has only been demonstrated in human cells and is unclear whether it is conserved in other mammals. METHODOLOGY/PRINCIPAL FINDINGS In the present study, we evaluated RNAa in cells derived from four mammalian species ...

Colonies of co-operatively breeding African mole-rats have traditionally been thought to be composed of a single breeding female, one or two breeding males, and their offspring. In the naked mole-rat (Heterocephalus glaber), the occurrence of facultative inbreeding means incest avoidance cannot prevent reproduction in subordinate group members, and physiological suppression of reproductive func...

Presented is an African giant rat (Cricetomys gambianus) following zinc ingestion. The sick rat was lethargic, withdrawn, had soft, mucus-impregnated faeces and diahorrea, foot twitching and icterus. Comparative age, sex and body weight (b.wt.)-matched analyses were made with a healthy giant rat. Twelve-hourly Urine volume (UV), Haematocrit (Hct), urinary glucose, plasma zinc and Alkaline Phosp...

The toxicity and mutagenic potential of most African plants implicated in the management of cancer have not been investigated. The ethanolic extracts of selected Nigerian plants were subsequently studied using the brine shrimp lethality tests, inhibition of telomerase activity and induction of chromosomal aberrations in vivo in rat lymphocytes. Morinda lucida root bark, Nymphaea lotus whole pla...
