Cytotoxicity of 35 medicinal plants from Sudan towards sensitive and multidrug-resistant cancer cells
2015
Abstract Background Cancer is a complex disease with multiple genetic and epigenetic alterations. Since decades, the hallmark of cancer therapy is chemotherapy. Cytotoxic drugs erase rapidly dividing cells without sufficient differentiation between normal and cancerous cells resulting in severe side effects in normal tissues. Recently, strategies for cancer treatment focused on targeting specific proteins involved in tumor growth and progression. The present study was designed to investigate the cytotoxicity of 65 crude extracts from 35 Sudanese medicinal plants towards various cancer cell lines expressing molecular mechanisms of resistance towards classical chemotherapeutics (two ATP-bindi…
Assessing drought vulnerability and adaptation among farmers in Gadaref region, Eastern Sudan
2018
Agricultural productivity in rural areas is severely affected by climate variability, and this elevates the vulnerability of rural households to food insecurity. This study examines the socio-economic vulnerability of farmers who are susceptible to droughts in the five agricultural-based regions of Gadaref, Eastern Sudan. A survey was carried out in 500 households to collect data on socio-economic and livelihood indicators. The data analyzed from these indicators were used to generate the three components of drought vulnerability: exposure, sensitivity and adaptive capacity. The analysis revealed that the regions deemed to be most vulnerable to both drought and climate variability were also…
Focused ultrasound to diagnose HIV-associated tuberculosis (FASH) in the extremely resource-limited setting of South Sudan: a cross-sectional study
2019
ObjectiveOur cross-sectional study aimed at evaluating the diagnostic performance of Focused Assessment with Sonography for HIV-associated tuberculosis (FASH) to detect extrapulmonary tuberculosis in extremely resource-limited settings, with visceral leishmaniasis as a differential diagnosis with overlapping sonographic feature.DesignCross-sectional study.SettingVoluntary Counselling and Testing Centre (VCT) of Yirol Hospital, South Sudan.ParticipantsFrom May to November 2017, 252 HIV-positive patients out of 624 newly admitted to VCT Centre were registered for antiretroviral treatment. According to the number of trained doctors available to practise ultrasound (US) scan, a sample of 100 pa…
Border diplomacy and state-building in north-western Ethiopia,c. 1965–1977
2017
In the first half of the twentieth century, the north-western lowlands of imperial Ethiopia were the typical interstitial frontier of the Ethiopian–Sudanese borderlands. Starting in the early 1960s, a cash crop revolution paved the way to the transformation of the Mazega into a settlement frontier and the emergence of a dispute with Sudan for demarcation of the international border. This article explores the entanglement between the political economy of frontier governance and border diplomacy in the contested area. It highlights how the management of the border dispute was deeply affected by the contradictory interests of the various layers of government and “twilight” entities that projec…
Development of a method for the analysis of seven banned azo-dyes in chilli and hot chilli food samples by pressurised liquid extraction and liquid c…
2008
An automated, confirmatory and sensitive procedure has been developed and validated for the determination of Sudan (I-IV), Sudan Orange G, Sudan Red 7B and Para Red in hot chilli food samples. The proposed method includes pressurised liquid extraction (PLE) with acetone, gel permeation chromatography (GPC) clean-up and detection by liquid chromatography (LC) coupled to electrospray ionization in positive mode tandem mass spectrometry (ESI-MS-MS). The main parameters affecting the performance of the different ionization sources and PLE parameters were previously optimised using statistical design of experiments (DOE). The method was in-house validated on chilli powder and chilli meat. Linear…
Solving underwater crimes: development of latent prints made on submerged objects.
2013
Underwater crime scenes always present a challenge for forensic researchers, as the destructive effect of water considerably complicates the chances of recovering material of evidential value. The aim of this study is to tackle the problem of developing marks that have been left on submerged objects. Fingermark deposition was randomly made on two surfaces - glass and plastic whilst the material was submerged under tap water and then left for one to fifteen days before drying and development. For their later development, various reagents - Black Powder, Silver Metallic Powder, Fluorescent Powder, Sudan Black (powder and solution) and Small Particle Reagent - were used and the effectiveness o…

I due Sudan: avamposti cinesi in Africa
2022
L’atteggiamento della Cina nei confronti della politica estera è parecchio mutato dagli anni Cinquanta ad oggi. Senza dubbio le relazioni Cina–Africa, costituiscono uno snodo interessante della politica estera cinese a partire dalla Conferenza di Bandung del 1955. All’indomani della caduta del muro di Berlino, la Cina si rese conto dello sbilanciamento geopolitico a favore degli Stati Uniti dovuto al repentino dissolvimento del blocco sovietico. Da circa 30 anni la Cina ha riconsiderato il peso politico rappresentato dai paesi africani, rivalutandone così il ruolo strategico nella difficile scalata ai vertici del sistema internazionale. In questo contributo si focalizza l'attenzione sull'in…
More about the developing of invisible lipstick-contaminated lipmarks on human skin: The usefulness of fluorescent dyes
2006
At the present time fingerprints are one of the simplest, and most reliable means of identification. Increasingly, crime scene investigators look for palm, foot, ear or lip prints. With regard to lip prints, the use, very common today, of protective or permanent lipsticks allow the production an invisible lipmark (or invisible lipstick-contaminated lipmark) which is possible to develop. Some results have already been published about developers useful for different kinds of surfaces (both porous and non-porous) as well as those which are more efficient in case of old or recent prints. The latest studies are about the developing on human skin, and they prove the usefulness of lysochromes (spe…
Narratiivinen tutkimus hengellisten laulujen ja seurakuntayhteyden merkityksistä eteläsudanilaisille maahanmuuttajille
2014
Tutkimuksen tarkoituksena oli selvittää, miten kristityt eteläsudanilaiset maahanmuuttajat ovat kokeneet hengelliset laulut ja seurakuntayhteyden oman elämänsä eri vaiheissa. Tutkimuksen kiinnostuksen kohteena olivat erityisesti hengellisten laulujen ja seurakuntayhteyden merkitykset eteläsudanilaisten identiteetin tukena ja toisaalta niiden vaikutukset nykyiseen asuinmaahan Suomeen kotoutumisessa. Tutkimukseen osallistui neljä eteläsudanilaista miestä samasta suomalaisesta evankelis-luterilaisesta seurakunnasta. Tutkimuksen aineisto kerättiin teemahaastatteluilla ja tulokset muotoutuivat aineiston narratiivisella analyysilla. Tutkimuksen tuloksena aineistosta muodostettiin neljän tutkimuks…
