A divergent Anaplasma phagocytophilum variant in an Ixodes tick from a migratory bird; Mediterranean basin

2020

Anaplasma phagocytophilum (AP) has vast geographical and host ranges and causes disease in humans and domesticated animals. We investigated the role of northward migratory birds in the dispersal of tick-borne AP in the African-Western Palearctic. Ticks were collected from northward migratory birds trapped during spring migration of 2010 at two localities in the central Mediterranean Sea. AP DNA was detected by PCR (gltA and 16S rRNA) and variant determination was performed using ankA sequences. In total, 358 ticks were collected. One of 19 ticks determined as Ixodes was confirmed positive for AP DNA. The tick was collected from a woodchat shrike (Lanius senator senator) trapped in Greece, a…

Ode laica per Chibok e Leah

2019

The volume contains two short poems by Nigerian Nobel Laureate Wole Soyinka ("No, He Said!", dedicated to Nelson Mandela, from the Author's 1988 classic collection "Mandela's Earth and Other Poems", and the recent "Mandela Comes to Leah", written purposely for this volume), along with the most recent long poem in five parts "A Humanist Ode to Chibok, Leah", published in English for the first time in 2019. The poem, and indeed the entire volume, denounces all forms of fundamentalism and fanaticism as opposed to secular humanism. Soyinka pays tribute to the girls abducted in Chibok and 15 year-old Leah Sharibu, one of the 108 girls abducted from Dapchi in 2018, comparing her firm refusal to r…

The Affective Turn and Sacred Femininity in African American Women's Literature

2017

Després del llarg viatge a través de l’Atlàntic a bord dels vaixells esclavistes, els africans van veure’s obligats a enfrontar-se a la seua completa alienació física, social i també espiritual en les terres de l’anomenat ‘Nou Món’. La seua anterior concepció de l’univers com a un lloc on poden exisitir-hi un ventall il·limitat de déus es va veure estroncat per la imposició social d’un univers on l’esclau va perdre tant el seu sentit d’espai com de temps. Així doncs, la evolució històrica del poble afroamericà s’esmerça en conrear una concepció sagrada del seu entorn des del mateix moment en que arriben a terres americanes. Aquesta obligada gestació espiritual els commina a acollir i, alhor…

Climate change impact on the West African monsoon from June to October.

2015

Sixteen CMIP5 models are used toanalyse how climate changes over the West African Monsoon region between a “future period”, defined from 2031 to 2070under the rcp4.5 emission scenario, and the “current period”, defined from 1960 to 1999 under the historical emissionscenario. The results show an increase of the September to October rainfall amounts. Circulation anomalies include of anincreases of sea-level pressure over the Mediterranean Sea and Europe that allow a strengthening of the moisture flux fromEuro-Mediterranean regions into the Sahel. These changes are stronger in autumn.

Pharmacogenomics of Cameroonian traditional herbal medicine for cancer therapy

2011

Abstract Ethnopharmacological relevance A socio-economic burden associated with cancers is reported in Africa. Ethnopharmacological usages such as immune and skin disorders, inflammatory, and others chould be considered when selecting plants used to treat cancer, since these reflect disease states bearing relevance to cancer or a cancer symptoms. Materials and methods Documented compounds of Cameroonian medicinal plants were used as keywords in the National Cancer Institute (NCI) database to establish a library of cytotoxic compounds. Cellular and pharmacogenomic profiling was then performed for the 10 most cytotoxic natural products. By COMPARE and hierarchical cluster analyses, candidate …

In vitro pro-apoptotic and anti-migratory effects of Treculia africana Decne. (Moraceae) and Entandrophragma angolense Welw (Meliaceae) extracts on p…

2021

Abstract Prostate cancer is the second leading cause of cancer deaths in men and there is an increasing interest in chemoprevention to fight it. The authors sought a scientific rationale for the traditional use of six Cameroonian medicinal plants for the treatment of prostate inflammation/tumour. The prostate cells viability incubated with each ethanolic plant extract was determined after 24, 48 and 72 h using the MTT assay. The antitumor mechanisms of promising extracts [Treculia africana (TA) and Entandrophragma angolense (EA)] were further assessed by evaluating cell growth, cell proliferation, cell cycle, cell death mechanisms and cell migration. Only TA and EA significantly inhibited L…

Ceramica da cucina dalla "Zona Mura" a Marsala. Le importazioni africane

2014

Object of this written are African cooking ware pieces found during the excavations of the so-called “Zona Mura” in the Archaeological Park of Marsala. Supported by the Soprintendenza BB.CC.AA. of Trapani, research in collaboration with the Universities of Hamburg and Palermo on the topic of “Lilybaeum Archaeological Project” are still in course of making. The stratified kitchen pottery considered was carried out nearby the fortifications’ north-west sector, which showed the remains of structures of Roman age that probably belong to some fortification walls and also to three insulae set in the southern part of the surveyed area. The dynamic pattern of relations between ceramics of different…

: Evolution of the examination at the end of college in sub-Saharan Africa

2004

The evolution of schooling in the developing systems in sub-Saharan Africa has brought a sizeable new population into the colleges. Unfortunately, the scarcity of resources and the need to pursue development of basic education prevents maintaining this population in the lycees. Thus the examination at the end of college becomes the focus of very stressful management of different currents and finds itself divided about aims which are not easy to reconcile. Original solutions can be found, as is the case in Mauretania, while the combination of better-known solutions may allow this examination to deal with these contradictions.
