Nucleotide sequence analyses of the Pvs48/45 and Pvs47 genes were conducted in 46 malaria patients from the Republic of Korea (ROK) (n = 40) and returning travellers from India (n = 3) and Indonesia (n = 3). The domain structures, which were based on cysteine residue position and secondary protein structure, were similar between Plasmodium vivax (Pvs48/45 and Pvs47) and Plasmodium falciparum (Pfs48/45 and Pfs47). In comparison to the Sal-1 reference strain (Pvs48/45, PVX_083235 and Pvs47, PVX_083240), Korean isolates revealed seven polymorphisms (E35K, H211N, K250N, D335Y, A376T, I380T and K418R) in Pvs48/45. These isolates could be divided into five haplotypes with the two major types having frequencies of 47.5% and 20%, respectivelfy. In Pvs47, 10 polymorphisms (F22L, F24L, K27E, D31N, V230I, M233I, E240D, I262T, I273M and A373V) were found and they could be divided into four haplotypes with one major type having a frequency of 75%. The Pvs48/45 isolates from India showed a unique amino acid substitution site (K26R). Compared to the Sal-1 and ROK isolates, the Pvs47 isolates from travellers returning from India and Indonesia had amino acid substitutions (S57T and I262K). The current data may contribute to the development of the malaria transmission-blocking vaccine in future clinical trials.

BACKGROUND: Low socioeconomic status (SES) is consistently associated with higher mortality in high income countries. Only few studies have assessed this association in low and middle income countries, mainly because of sparse reliable mortality data. This study explores SES differences in overall and cause-specific mortality in the Seychelles, a rapidly developing small island state in the African region. METHODS: All deaths have been medically certified over more than two decades. SES and other lifestyle-related risk factors were assessed in a total of 3246 participants from three independent population-based surveys conducted in 1989, 1994 and 2004. Vital status was ascertained using linkage with vital statistics. Occupational position was the indicator of SES used in this study and was assessed with the same questions in the three surveys. RESULTS: During a mean follow-up of 15.0 years (range 0-23 years), 523 participants died (overall mortality rate 10.8 per 1000 person-years). The main causes of death were cardiovascular disease (CVD) (219 deaths) and cancer (142 deaths). Participants in the low SES group had a higher mortality risk for overall (HR = 1.80; 95% CI: 1.24-2.62), CVD (HR = 1.95; 1.04-3.65) and non-cancer/non-CVD (HR = 2.14; 1.10-4.16) mortality compared to participants in the high SES group. Cancer mortality also tended to be patterned by SES (HR = 1.44; 0.76-2.75). Major lifestyle-related risk factors (smoking, heavy drinking, obesity, diabetes, hypertension, hypercholesterolemia) explained a small proportion of the associations between low SES and all-cause, CVD, and non-cancer/non-CVD mortality. CONCLUSIONS: In this population-based study assessing social inequalities in mortality in a country of the African region, low SES (as measured by occupational position) was strongly associated with overall, CVD and non-cancer/non-CVD mortality. Our findings support the view that the burden of non-communicable diseases may disproportionally affect people with low SES in low and middle income countries.

Objective: We assessed the awareness, treatment and control of hypertension in the Seychelles between 1989 and 2013. In the Seychelles, heath care is free to all inhabitants within a national health system, inclusive all hypertension medications. Design and method: Four surveys were conducted in 1989, 1994, 2004 and 2013 (Seychelles Heart Studies I, II, III and IV) in random samples of the population aged 25-64 (N >1000 and participation rate >75% in each sur acceptance of the program, though no objective index could be calculated. In total, 15% of device measurements were above high normal values and would correspond to either newly diagnosed HNT (second measurement required) or to poorly controlled known HTN. It should be stressed that 53 women without HTN who completed the questionnaire had abnormal BP values, including the 29 women who also contacted the research team. It could be speculated that approximately 2% of women would be first diagnosed with HTN following the completion of the initial phase of the screening program. Conclusions: Hypertension screening in the hair salon setting was proved to be conveniently applicable and well accepted both by owners and by customers and could lead to the new diagnosis of hypertension for 2% of the female clients. Further research is warranted to assess the effectiveness of the program.

Background: Malaria has come near eradication at archipelago of Cabo Verde in 1970. Infections are now only observed in Santiago, where outbreaks occur. In these islands, malaria is considered by the international community as being of limited risk and, therefore, no prophylaxis is recommended. Since the understanding of factors that determine malaria outbreaks are crucial for controlling the disease, the present study aimed to investigate if the malaria infections observed in Santiago Island are maintained in isolated foci and in asymptomatic individuals.

We present the first parasitological, molecular and longitudinal analysis of an isolated outbreak of malaria. This outbreak occurred on Santiago Island (Republic of Cabo Verde), a region where malaria is hypoendemic and controlled, and thus the population is considered non-immune. Blood samples were collected from the inhabitants over 1 month and during cross-sectional surveys in the following year. The presence and nature of the parasites was determined by PCR. Plasmodium falciparum was the only species detected. Genetic analysis revealed that the circulating parasites were genetically homogeneous, and probably clonal. Gametocytes were found throughout this period. Our data suggest that this represented a focal outbreak, resulting in the infection of at least 40% of the villagers with a clonal parasite line. Thus, P. falciparum infections can persist for at least 1 year in a substantial proportion (10%) of the hosts. Implications for malaria control and the interpretation of epidemiological data are discussed.

Background: Few data exist on secular trends of high blood pressure (HBP) detection and control in low and middle income countries, particularly in the African region. This study examines trends of HBP over 25 years based on 4 independent population surveys. In the Seychelles, heath care is free to all inhabitants within a national health system, inclusive all HBP medications. Previous studies have shown a transition from traditional to cardiometabolic cardiovascular risk factors in Seychelles. Age adjusted cardiovascular disease mortality rates is high but decreasing over the last two decades.

ETHNOPHARMACOLOGICAL RELEVANCE: The aim of this survey was to describe which traditional medicines (TM) are most commonly used for non-communicable diseases (NCD - diabetes, hypertension related to excess weight and obesity) in Pacific islands and with what perceived effectiveness. NCD, especially prevalent in the Pacific, have been subject to many public health interventions, often with rather disappointing results. Innovative interventions are required; one hypothesis is that some local, traditional approaches may have been overlooked. MATERIALS AND METHODS: The method used was a retrospective treatment-outcome study in a nation-wide representative sample of the adult population (about 15,000 individuals) of the Republic of Palau, an archipelago of Micronesia. RESULTS: From 188 respondents (61% female, age 16-87, median 48,), 30 different plants were used, mostly self-prepared (69%), or from a traditional healer (18%). For excess weight, when comparing the two most frequent plants, Morinda citrifolia L. was associated with more adequate outcome than Phaleria nishidae Kaneh. (P=0.05). In case of diabetes, when comparing Phaleria nishidae (=Phaleria nisidai) and Morinda citrifolia, the former was statistically more often associated with the reported outcome "lower blood sugar" (P=0.01). CONCLUSIONS: Statistical association between a plant used and reported outcome is not a proof of effectiveness or safety, but it can help select plants of interest for further studies, e.g. through a reverse pharmacology process, in search of local products which may have a positive impact on population health.

The goal of the present work was to describe the wood fuel market of Ukraine and the Republic of Belarus, to estimate wood fuel potential and to research opportunities of wood fuel trading. Nowadays the wood waste, wood residues and by-products are becoming more and more potential raw materials for energy production. Against the background of unstable prices of traditional energy sources and environmental degradation, European States are planning to get 12% of energy from alternative sources already in 2010. Wastes of wood-working and agricultural productions are such sources. At present time the most popular wood biofuels are wood pellets, briquettes, wood chips and logs. Ukraine and the Republic of Belarus have a rather big potential of wood fuel resources. But wood fuels markets of these countries are on the entry level and quite disorganized. There is almost no domestic usage of wood biofuel. All produced pellets, briquettes as well as wood chips and logs go to the export, but the volumes are not high at present time. Ukraine and the Republic of Belarus have a very suitable geographical location. The most promising directions of wood fuel trading are developed wood fuel markets of Northern countries, Austria, Germany as well as actively developing markets of Poland and Hungary. At the long distance truck and sea transportation are the most appropriate. At a short distance cheap transportation by rail is more suitable. Thereby export is a potential opportunity for development of wood fuel production and in the future for usage in the researched countries.

De afrikanska ekonomierna växer med nära fyra procent per år och detta är en god indikation på kontinentens växande betydelse. Under kalla kriget hade afrikanska regeringar haft ett begränsat utrymme för opportunistisk köpslående, och därmed även en marginal att positionera sig strategiskt. Alltför ofta uppmuntrade och beskyddade stormakterna diktatorer och små lokala eliter som främst ville berika sig själv. I och med att globaliseringen tog fart och USA allt mera kom att dominera globalt, började en ny era i fråga om förändringar. Trots dessa förändringar på den globala arenan, har Afrika som kontinent hamnat i bakgrunden och jämfört med andra utvecklingsländer har Afrika attraherat ett fåtal utländska investeringar. Fortfarande, speciellt i Norden, finns det lite kunskap om hur utländska företag expanderar sin affärsverksamhet på den afrikanska kontinenten. Det råder brist på empiriska undersökningar om vilken inverkan afrikanska institutionella förändringar och lokala affärsmiljöer har på internationaliseringen och på de utländska företagens affärsutvecklingsstrategier på den afrikanska kontinenten. Med denna avhandling vill jag lyfta fram ett exempel på ett land (Sydafrika), som har lyckat dra nytta av de förändringar som 1990-talet förde med sig. I denna avhandling har jag intervjuat olika personer i ledande positioner inom olika finländska företag i Finland och i Sydafrika. Avhandlingen skapar en referensram för att öka förståelse och fördjupa analys av hur en kombination av olika interna och externa resurser ökar företagens konkurrenskraft och på det sättet bidrar till en framgångsrik affärsutveckling i Afrika. De politiska och sociala aktörerna samt aktörerna inom affärslivet besitter resurser som ambitiösa företag kan dra nytta av i sin strävan att erövra de nya framgångsrika marknaderna i Afrika. Gradvis ökar finländska företag sina insatser på den afrikanska kontinenten i strävan att skapa mervärde för sina kunder. Den värdeskapande processen gör att parterna måste närma sig varandra utgående från sina egna strategiska målsättningar. Hittills har finländska företag varit intresserad att sälja till Afrika men inte intresserad att köpa därifrån. Förutom de praktiska råden till olika företag, föreslår avhandlingen hur den finska staten och den sydafrikanska staten kunde agera tillsammans för att främja ömsesidigt handelsutbyte.

To improving efficiency and transparency of government services, government authorities may increase the frequency of interaction between citizens and government as well as improving the quality of the government services and trust. Electronic Government (E-Government) in definition is the delivery of government services to citizens, businesses, and government organizations through the use of internet, web based applications, and Information and Communication Technologies (ICTs) is the solution to build more reliable and efficient contact with citizens. Like the developing and developed countries, Iran also has been processing the various aspects of ICT, IT, and e-Government. Though, in order to implement and improve e-Government; Iran has faced with some obstacles. Therefore, the purpose of this thesis is to study progress of e- Government and identify obstacles of implementing and improving e Government in Iran. In this thesis, based on the literature review, the progress of e-Government in Iran was studied and various obstacles were identified. Therefore, as a result, e- Government of Iran is said to be in the transactional stage of the United Nations’ e-Government maturity stages. In addition, establishing more reliable, efficient, and accurate e-Government initiatives, plans, guidelines, and strategies will extremely enhance e-Government status of Iran. On the other hand, the needs of the citizens should always be under consideration when implementing and improving e-Government services; because citizens are considered to be at the core of every e-Government services and the responsibilities of the authorities.
