Energy Consumption Pattern of a Decentralized Community in Oyo State, Nigeria

Energy is required in the manufacture of various products and in the movement of goods and services within and outside a country. Energy consumption patterns, which consist of energy sources, quantities and the demographics of the consumers, help in drawing a clearer picture of the economic situation of the location. This work involves a survey of the household energy consumption pattern carried out in a decentralised community. As established from research, there is a direct correlation between economic development and energy consumption. It is therefore imperative to study the energy usage of rural areas to help decision makers tackle their energy problems. Energy conversion methods were employed for the conversion of the raw data collected into energy units to determine the quantities of energy consumed in various sectors at the Alagbaa community in Akanran, Ona Ara Local Government Area, Oyo State, Nigeria. The survey covered a heterogeneous population of different income groups and social groups and studies were carried out on the total and average quantities of energy consumed in the domestic, transportation and agricultural sectors. Home electrification accounted for 37% of the total energy used by a household while transportation, cooking and agriculture accounted for 35%, 13% and 15% respectively. From the study, it was found that economic inequality is also displayed in the choice of energy sources with higher deviation found in the total amount in the use of energy. It was also found that the least conventional source of energy, firewood, showed higher deviation. It also revealed that 50% of the energy used was channelled to non-economic activities. &nbsp

Computer-aided drug design in anti-cancer drug discovery: What have we learnt and what is the way forward?

The escalating prevalence of cancer on a global scale, coupled with the inadequacies of present-day therapies and the emergence of drug-resistant cancer strains, has necessitated the development of additional anticancer drugs. The traditional drug discovery process is long and complex, and the high failure rate of new drugs in clinical trials further highlights the need for computational approaches in anticancer drug discovery. Computer-aided drug design (CADD), including molecular docking, molecular dynamics simulations, QSAR analysis, and machine learning, are employed to predict the efficacy of potential drug compounds and pinpoint the most auspicious compounds for subsequent testing and advancement. This article provides an overview of contemporary computational approaches employed in the design of anti-cancer drugs. It highlights a range of small molecules that have been identified as capable of impeding cancer growth and migration through various mechanisms, including cell cycle arrest/apoptosis, signal transduction inhibition, angiogenesis, epigenetics, and the hedgehog pathway. It also examines the constraints of computational techniques and presents remedies to surmount these limitations in the development and identification of efficacious anticancer compounds

Pragmatic solutions to reduce the global burden of stroke: a World Stroke Organization–Lancet Neurology Commission

Stroke is the second leading cause of death worldwide. The burden of disability after a stroke is also large, and is increasing at a faster pace in low-income and middle-income countries than in high-income countries. Alarmingly, the incidence of stroke is increasing in young and middle-aged people (ie, age <55 years) globally. Should these trends continue, Sustainable Development Goal 3.4 (reducing the burden of stroke as part of the general target to reduce the burden of non-communicable diseases by a third by 2030) will not be met. In this Commission, we forecast the burden of stroke from 2020 to 2050. We project that stroke mortality will increase by 50%—from 6·6 million (95% uncertainty interval [UI] 6·0 million–7·1 million) in 2020, to 9·7 million (8·0 million–11·6 million) in 2050—with disability-adjusted life-years (DALYs) growing over the same period from 144·8 million (133·9 million–156·9 million) in 2020, to 189·3 million (161·8 million–224·9 million) in 2050. These projections prompted us to do a situational analysis across the four pillars of the stroke quadrangle: surveillance, prevention, acute care, and rehabilitation. We have also identified the barriers to, and facilitators for, the achievement of these four pillars. Disability-adjusted life-years (DALYs) The sum of the years of life lost as a result of premature mortality from a disease and the years lived with a disability associated with prevalent cases of the disease in a population. One DALY represents the loss of the equivalent of one year of full health On the basis of our assessment, we have identified and prioritised several recommendations. For each of the four pillars (surveillance, prevention, acute care, and rehabilitation), we propose pragmatic solutions for the implementation of evidence-based interventions to reduce the global burden of stroke. The estimated direct (ie, treatment and rehabilitation) and indirect (considering productivity loss) costs of stroke globally are in excess of US$891 billion annually. The pragmatic solutions we put forwards for urgent implementation should help to mitigate these losses, reduce the global burden of stroke, and contribute to achievement of Sustainable Development Goal 3.4, the WHO Intersectoral Global Action Plan on epilepsy and other neurological disorders (2022–2031), and the WHO Global Action Plan for prevention and control of non-communicable diseases. Reduction of the global burden of stroke, particularly in low-income and middle-income countries, by implementing primary and secondary stroke prevention strategies and evidence-based acute care and rehabilitation services is urgently required. Measures to facilitate this goal include: the establishment of a framework to monitor and assess the burden of stroke (and its risk factors) and stroke services at a national level; the implementation of integrated population-level and individual-level prevention strategies for people at any increased risk of cerebrovascular disease, with emphasis on early detection and control of hypertension; planning and delivery of acute stroke care services, including the establishment of stroke units with access to reperfusion therapies for ischaemic stroke and workforce training and capacity building (and monitoring of quality indicators for these services nationally, regionally, and globally); the promotion of interdisciplinary stroke care services, training for caregivers, and capacity building for community health workers and other health-care providers working in stroke rehabilitation; and the creation of a stroke advocacy and implementation ecosystem that includes all relevant communities, organisations, and stakeholders
