Introduction:Hypertension is progressively becoming more prevalent in Nigeria. The purpose of the study was to assess the risk factors and occurrence of hypertension among Fulani herdsmen in Nigeria.Methodology:A descriptive longitudinal study on hypertension was conducted among Fulani herdsmen residing in rural communities of Ilorin East and Moro Local Government Areas (LGAs) of Nigeria, from the age of 18 years and above. Eight hundred and seventy–two (872) consenting subjects completed a standardized questionnaire. Blood pressure, weight and height were measured and recorded using standard calibrated equipment.Results:Of the 872 herdsmen, 351 (40.3%) were aged 18–30 years and 632 (72.5%) migrated from the North–West zone of Nigeria. Almost all (n=858, 98.4%) of the subjects were ignorant of hypertension. Overweight and obesity were uncommon among the subjects. The occurrence of hypertension was 17.3% with overall average systolic blood pressure (BP) of 128.8±12.3 mmHg and diastolic BP of 84.0±8.0 mmHg. Risk factors of hypertension were types of diet [OR 0.578; 95% confidence interval (CI) 0.113–11.418, p< 0.028], smoking habit [OR 5.147; CI: 1.023–25.884, p < 0.017] and age [OR 2.656; CI: 0.682–8.556, p < 0.031].Conclusion: Majority of hypertensive herdsmen were not aware of their status, signifying a high incidence of undiagnosed and un-controlled BP among these subjects. Public health awareness on the risk factors of hypertension is essential to reduce the burden among this population. Further research is also necessary to measure the trends of hypertension among this populationBangladesh J Medicine Jul 2016; 27(2) : 48-54

i. A four-year survey, involving the investigation of over 1,000 cases of strike, has been made of the species concerned in sheep myiasis throughout the British Isles. In all regions, L. sericata is the principal maggot-fly. In Scotland, Northern England and North Wales, L. caesar is an important species. Phormia terraenovae has much the same distribution, as a striking species, as L. caesar, except that it apparently does not strike sheep in North Wales ; in the areas where it occurs it follows L. caesar in importance. These two species are apparently capable of acting as primary flies. Calliphora erythrocephala, and, more rarely, Calliphora vomitoria occur fairly generally over the country, but only in very low incidence. Larvae of Muscina spp. have been recovered from only three cases, one each in Scotland, England and Ireland. The two closely related species, L. caesar and L. illustris have only been separated in a few instances, and there is not sufficient evidence for the latter species, but it would seem to be more common in lowland areas than in the north and west.ii. The incidence of “ alternative ” species, i.e. species other than L. sericata, decreases from north-west to south-east of Britain ; they occurred in 47 per cent. of strikes north and west of a line from Inverness to Glasgow, and in over 20 per cent. of the cases between this and a line from East Lothian to Morecambe Bay, south of the Lake District. In the fringe of hill country east and south of this, e.g., the Cheviots, Pennines and Wales, about 10 per cent. of cases contained “ alternative ” species. Farther to the south-east and south “ alternatives ” were rare.iii. Within the above belts of territory, the “ alternative ” species appear to have certain common regions which are favourable for the striking habit, although the limits of strike-distribution for each species are apparently not quite coincident. These “ favourable regions ” are discussed in the text. With Phormia terraenovae the habit appears to be restricted to favourable regions, where it occurs in moderately high incidence ; with L. caesar strike occurs in relatively high incidence in favourable regions, but is also present, in low proportion, throughout the country, while the Calliphora species strike in low proportion in favourable regions, and sporadically elsewhere.iv. Phormia and L. caesar have a higher relative incidence in the first half of the fly season than in the later half ; C. vomitoria may be restricted to the extremes of the season-May, June and September.

Oreochromis mossambicus is currently receiving much attention as a candidater species for aquaculture programs within Southern Africa. This has stimulated interest in its breeding cycle as well as the morphological characteristics of the gonads. Limited information is available on SEM and TEM observations of the male gonads. It is known that the testis of O. mossambicus is a paired, intra-abdominal structure of the lobular type, although further details of its characteristics are not known. Current investigations have shown that spermatids reach full maturity some two months after the female becomes gravid. Throughout the year, the testes contain spermatids at various stages of development although spermiogenesis appears to be maximal during November when spawning occurs. This paper describes the morphological and ultrastructural characteristics of the testes and spermatids.Specimens of this fish were collected at Syferkuil Dam, 8 km north- west of the University of the North over a twelve month period, sacrificed and the testes excised.

Statistical data on reserves, production and exports of Russian oil are provided in the article. The author pays special attention to the expansion of opportunities of sea oil transportation by construction of new oil terminals in the North-West of the country and first of all the largest terminal in Murmansk. In his opinion, one of the main problems in this sphere is prevention of ecological accidents in the process of oil transportation through the Baltic sea ports.

The study of paleogeography of lakes is an actual and important direction in modern science. As part of the study of lakes in the North-West of the Karelian Isthmus, this analysis will establish the dynamics of salinity of objects, which will allow to reconstruct changes in the level of the Baltic Sea in the Holocene.
