Epidemiology of Eye Diseases among Timber Workers in Owerri, Nigeria

Anepidemiological studyof the Timber Industry in Owerri, Nigeria was carriedout. It assessed the burden of eye diseases among Timber workers in terms of magnitude, causes and time. Certain eye diseases, notably, conjunctivitis, foreign bodies/injuries/traumas, pterygia, pinguecula and uveitis, each, accounting for 39.52%, 31.10%, 12.53%, 7.34% and 2.16% respectively, were found among theworkers. Theworkerswho have spent close to 16 -20 years in the industry recorded the highest prevalence (21.92%) of the eye diseases, while those who have spent about 1-5years recorded the least prevalence of 4.57%. Theworking environment was unsanitary and noworker wore any protective goggle. These two latter factors are believed to have contributed to the prevalence of these eye diseases among the workers.

CONTRIBUTION OF FORMAL FINANCIAL INSTITUTIONS TO CASSAVA PROCESSING IN BENUE STATE, NIGERIA

The study was carried out to assess the contribution of Formal Financial Institutions (FFIs) to income of cassava processors in Benue state, Nigeria. Multistage sampling technique was used to select 234 cassava processors from 18 communities in the state. Data on credit sources and uses, processing activities and income were collected using structured questionnaires. The data were analyzed using descriptive and inferential statistics while the impact of the credit was assessed using the before and after comparison. The result shows that about a third of the processors had access to formal credits. The Nigerian Agricultural Bank ranked highest (83%) in terms of patronage. Commercial and microfi-nance banks«¤?? lending to cassava processing represented about 12% and 5% respectively of the total credit received. Majority (70%) of the processors received less than N100, 000 per year; an average of N63,152, which is about 12% of total amount, required. Credit financing from formal financial institu-tions was found to have significant effects on both the output of garri and flour processed and the profit from garri, flour and chips«¤?? processing. The credit use structure shows that over 65% of the credit was use to increase processing scale, through increase in the purchase of raw tubers and payment for processing labour

Culture in sustainable infrastructure: the polycentric cultural framework model

The state of infrastructure and services is widely perceived as a measure of development and a major catalyst for growth in both developed and developing economies. However, financing, maintaining and replicating existing infrastructures in areas of need have been mostly ineffective. In view of the widespread failures and poor state of infrastructure and services, there is a need to review current delivery and procurement frameworks. Given that sustainable infrastructure is also an essential prerequisite for sustainable development, this paper presents a polycentric cultural framework for infrastructure and service delivery; a framework which emphasises the integration of infrastructure users, communities, public and private sectors throughout the process of conceptualisation to actual delivery of infrastructure, by taking the recipients’ culture, beliefs and values into account. The framework also emphasises the use of systemic referendum among stakeholders by way of the traditional consultative processes and the collaborative consensus paradigm to achieve an effective and sustainable delivery of infrastructure and services

Targeting RNS/caveolin-1/MMP signaling cascades to protect against cerebral ischemia-reperfusion injuries: potential application for drug discovery

Reactive nitrogen species (RNS) play important roles in mediating cerebral ischemia-reperfusion injury. RNS activate multiple signaling pathways and participate in different cellular events in cerebral ischemia-reperfusion injury. Recent studies have indicated that caveolin-1 and matrix metalloproteinase (MMP) are important signaling molecules in the pathological process of ischemic brain injury. During cerebral ischemia-reperfusion, the production of nitric oxide (NO) and peroxynitrite (ONOO-), two representative RNS, down-regulates the expression of caveolin-1 (Cav-1) and, in turn, further activates nitric oxide synthase (NOS) to promote RNS generation. The increased RNS further induce MMP activation and mediate disruption of the blood-brain barrier (BBB), aggravating the brain damage in cerebral ischemia-reperfusion injury. Therefore, the feedback interaction among RNS/Cav-1/MMPs provides an amplified mechanism for aggravating ischemic brain damage during cerebral ischemia-reperfusion injury. Targeting the RNS/Cav-1/MMP pathway could be a promising therapeutic strategy for protecting against cerebral ischemia-reperfusion injury. In this mini-review article, we highlight the important role of the RNS/Cav-1/MMP signaling cascades in ischemic stroke injury and review the current progress of studies seeking therapeutic compounds targeting the RNS/Cav-1/MMP signaling cascades to attenuate cerebral ischemia-reperfusion injury. Several representative natural compounds, including calycosin-7-O-β-D-glucoside, baicalin, Momordica charantia polysaccharide (MCP), chlorogenic acid, lutein and lycopene, have shown potential for targeting the RNS/Cav-1/MMP signaling pathway to protect the brain in ischemic stroke. Therefore, the RNS/Cav-1/MMP pathway is an important therapeutic target in ischemic stroke treatment.published_or_final_versio

John Esenwa oral history interview

This is an oral history interview with John Esenwa, a survivor of the Asaba Massacre, a mass killing of civilians which occurred in 1967 during the Nigerian Civil War. Esenwa, who was fourteen years old when the massacre took place, was attending boarding school in the Asaba area at the time; his school was about a mile from the city. When the soldiers entered the city, the support staff stopped coming to work, and the decision was made to close the school, but the teachers had trouble finding adequate transportation. One day, a cattle truck on its way to the Nigerian soldiers\u27 camp stopped at the school and offered some of the students a ride. Esenwa and several others accepted; on the road, Esenwa changed his mind, jumped off, and went back to the school. None of the children who accepted the ride were ever seen again. In this interview, Esenwa also comments on the causes of the Asaba Massacre and discusses potential ways to memorialize and identify the victims

Secondary stroke prevention: challenges and solutions

Charles Esenwa, Jose GutierrezDepartment of Neurology, College of Physicians and Surgeons, Columbia University Medical Center, New York, NY, USAAbstract: Stroke is the leading cause of disability in the USA and a major cause of mortality worldwide. One out of four strokes is recurrent. Secondary stroke prevention starts with deciphering the most likely stroke mechanism. In general, one of the main goals in stroke reduction is to control vascular risk factors such as hypertension, diabetes, dyslipidemia, and smoking cessation. Changes in lifestyle like a healthy diet and aerobic exercise are also recommended strategies. In the case of cardioembolism due to atrial fibrillation, mechanical valves, or cardiac thrombus, anticoagulation is the mainstay of therapy. The role of anticoagulation is less evident in the case of bioprosthetic valves, patent foramen ovale, and dilated cardiomyopathy with low ejection fraction. Strokes due to larger artery atherosclerosis account for approximately a third of all strokes. In the case of symptomatic extracranial carotid stenosis, surgical intervention as close as possible in time to the index event seems highly beneficial. In the case of intracranial large artery atherosclerosis, the best medical therapy consists of antiplatelets, high-dose statins, aggressive controls of vascular risk factors, and lifestyle modifications, with no role for intracranial arterial stenting or angioplasty. For patients with small artery occlusion (ie, lacunar stroke), the therapy is similar to that used in patients with intracranial large artery atherosclerosis. Despite the constant new evidence on how to best treat patients who have suffered a stroke, the risk of stroke recurrence remains unacceptably high, thus evidencing the need for novel therapies.Keywords: stroke mechanisms, stroke risk, hypertension, diabetes, dyslipidemi
