The skin aging process, which is prompted by environmental variables, is named untimely or extrinsic skin aging process and can be recognized from the sequentially (intrinsic) skin aging process by trademark skin aging signs. Albeit human skin goes about as a biological shield against pro-oxidative chemicals and physical air pollutants, prolonged or tedious presentation to abnormal amounts of these pollutants may have profound negative impacts on the skin. Sexual orientation contrasts in toxicity have been accounted for some substances. Youngsters are known to be increasingly defenseless against the antagonistic health impacts of air pollution. Environmental pollution by traffic is additionally connected with the event of indications of extrinsic skin aging. Heavy metals, for example, cadmium, lead and mercury are regular air pollutants that posture health hazards because of bioaccumulation. Ozone in the stratosphere has protective impacts by sifting solar UVR; be that as it may, in the troposphere ozone has toxic implications for skin. Because of scarcity of logical proof, there are no settled rules as of now accessible for protecting the skin against air pollution. Beside lessening presentation, potential protection techniques should concentrate on fixing the skin barrier, renewing antioxidant save, and diminishing inflammation brought about via air pollutants.
Liver cirrhosis with high IgG4 in a patient with, diabetes mellitus, ulcerative colitis with papillary thyroid cancer, is it all related ? which one to blame& is it time to raise awareness about IGG4 and hepatobiliary diseases
Back ground: There is possible etiological relation between high IgG4 in a patient with liver cirrhosis, ulcerative colitis, diabetes mellitus , prostatitis ,venous thrombosis and thyroid cancers and the use of immunosuppressive & biologic agents. Method: a study of patient with multiple organ involvement with persistently elevated IgG4.

This article covers the epidemiology, pathophysiology/complications and management of diabetic gastroparesis (DGP), and more broadly diabetic gastroenteropathy, which encompasses all the gastrointestinal manifestations of diabetes mellitus (DM). Hyperglycemia, autonomic neuropathy, and enteric neuromuscular inflammation and injury are implicated in the pathogenesis of delayed gastric emptying (GE). Initial options include dietary modifications, supplemental oral nutrition, and antiemetic and prokinetic medications. Patients with more severe symptoms may require a venting gastrostomy or jejunostomy and/or gastric electrical stimulation (GES). To date, few population-based studies have estimated the true prevalence and incidence of gastroparesis. Nonetheless, its prevalence appears to be rising, as does its incidence among minority populations, documented via hospitalizations, which can impose significant economic burdens on patients.
ANALYSIS OF BOKO HARAM INSURGENCY ACTIVITES IN NORTH EASTERN NIGERIA: A GEOGRAPHICAL INFORMATION SYSTEM APPROACH
Over the years, Nigeria as a Nation has been witnessing serious unrest characterized by the ethnic, political, farmer’s-herder’s conflict and activities of the insurgency. The north eastern geo-political zone of Nigeria was not left out of the activities. The activities of the Boko Haram insurgents has led to over ten thousand people losing their life and properties making many homeless. The paper is aimed at providing a comprehensive data and show the spatial distribution of activities of Boko Haram insurgency in Adamawa, Borno and Yobe States between 2009 and 2017. The paper utilizes secondary data from Armed Conflict Data (ACLED), printed materials, newspaper records, journals, and security agencies records. The method of analysis utilized in the study is Geographical Information System (GIS) approach using ArcGIS software and graphs to indicate the activities of the insurgency. The finding of the research shows that Borno State has the highest occurrence of insurgency and Yobe State recorded the lowest. The study concludes that the activities of the insurgents are more at the northern part and along the international boundaries.
Many fungi including Penicillium and Aspergillus species produces patulin in the contaminated foods. Patulin is a heterocyclic unsaturated lactone that reacts with SH group of biological molecules causing harmful effects in human and animal tissues. Hence, the present investigation was designed to evaluate the possible teratogenic effect of patulin (0.002mg/kg b. wt) which was examined through the induction of dominant lethal gene and the alteration in number of live births in the female rats . Results and Conclusion: patulin is a dangerous teratogen in rats. This was confirmed by the significant increase in the percentage of maternal and embryo toxicities.

This study analysed the long run relationship between economic growth, foreign direct investment, foreign trade, inflation, exchange rate, imports and exports for the period of 1980-2011 using annual time series analysis. It examined the dependency of economic growth on foreign trade, exchange rate, inflation and foreign direct investment. Trade openness, foreign direct investment and inflation are found stationary at level while imports, exports, exchange rate and economic growth are stationary at first difference. All the variables have long run relationship according to cointegration results. DOLS results showed that imports and exports have significant positive relationship, inflation and foreign trade have significant negative impact, and exchange rate and foreign direct investment have insignificant positive influence on economic growth. The negative impact of foreign trade can be overcome by producing import substitutes and creating conditions for trade surplus. Other policy reforms are also required to enhance the economic growth.
