Focused reservoir characterization: analysis of selected sand units using well log and 3-D seismic data in 'Kukih' field, Onshore Niger Delta, Nigeria.

This study focuses on the comprehensive reservoir characterization of the 'Kukih' Field within the onshore northeastern Niger Delta region, Nigeria. The absence of its detailed description with delineated reservoir properties, lateral continuity, and their use to identify potential reservoir quality and heterogeneity necessitated this study. Integrating well log and 3D seismic data, the investigation aims to elucidate reservoir properties, lithofacies, and depositional environments to unravel hydrocarbon potential.

Efficiency Assessment of Breast Clinics for Patients Under 35: A Comparative Analysis of Targeted Models in a University Hospital.

Despite the higher incidence of breast cancer in older age groups, it remains pertinent not to overlook breast cancer occurrence in those aged 35 years and below. Recent transitions toward targeted under-35 clinics in England aim to enhance efficiency and meet referral standards. Three models were planned, and we assessed the efficiency of each model.

Impella-Driven High-Risk Percutaneous Coronary Intervention: A Novel, Single Non-Surgical-Centre Case Report.

Complex percutaneous coronary intervention (PCI) procedures have been routinely performed in non-surgical centres in the UK for more than two decades. These procedures follow strict guidelines and recommendations by the British Cardiovascular Intervention Society to ensure a more effective running of PCI programs. Even more so, expected guiding principles necessary for the safe optimisation of complex PCI procedures have also been created.

Status of forest onchocerciasis in the Lower Cross River basin, Nigeria: entomologic profile after five years of ivermectin intervention.

In the Lower Cross River basin in Nigeria, no pre-control entomologic profile of Onchocerca volvulus infection in the local Simulium damnosum population was available prior to the initiation of an ivermectin control program in 1995. A longitudinal entomologic study was therefore carried out over a 12-month period (January-December 2001) at the Agbokim waterfalls and Afi River, which are breeding sites of S. damnosum in the river basin.

Electrophysiological and biochemical changes in rabbit hearts stored at 4 degrees C for 6 or 24 h.

This study examines the electrophysiological and metabolic changes that occur in rabbit hearts during hypothermic storage in vitro. Hearts were microperfused at 4 degrees C for 6 or 24 h with either normal Krebs-Henseleit buffer (KHB) or KHB containing 2,3-butanedione monoxime (BDM). After hypothermic storage, hearts were rewarmed to 37 degrees C with KHB.

1. This study examined the effects of altering nitric oxide levels with sodium nitroprusside or L-arginine in rat hearts stored hypothermically.2.

Effect of protein kinase C inhibitors and 2,3-butanedione monoxime on the long-term hypothermic preservation of isolated rat hearts.

1. This study examines the protective effect of staurosporine, chelerythrine, Ro 31-8220 and 2,3-butanedione monoxime in rat hearts during hypothermic storage. 2.

Long-term preservation of the rat isolated heart with staurosporine and 2,3-butanedione monoxime.

The present study was designed to investigate the effectiveness of staurosporine and 2,3-butanedione monoxime (BDM) in preserving cardiac function of long-term hypothermic-stored hearts. Rat isolated hearts were perfused very slowly at 4 degrees C for 16 hr with a storage buffer solution containing staurosporine and BDM. Heart functions were then examined during 2 hr of normothermic reperfusion.

Coronary vessels contain enzymes that liberate kinin-like vasodilator substances.

The presence of an acid optimum (pH 6) enzyme capable of generating a spasmogenic, vasodilator polypeptide from human plasma kininogen has been demonstrated in dog coronary arteries, veins and in the wall of the left ventricle. This enzyme also cleaved the tripeptide kallikrein substrate Val-Leu-Arg-pNA. Highest amounts were present in the coronary arteries.

Effect of dopexamine hydrochloride in the early stages of experimental myocardial infarction and comparison with dopamine and dobutamine.

The effect of dopexamine hydrochloride on myocardial performance, and on the susceptibility of the myocardium to generation of arrhythmias during the development of myocardial infarction has been compared with dopamine and dobutamine in 2 experimental models of myocardial ischemia. All 3 agents improved cardiac function in the presence of a developing infarct. Dopamine and dobutamine increased myocardial contractility (left ventricular dP/dt and left ventricular dP/dt/P), which would be expected to increase oxygen consumption and thus further compromise the ischemic myocardium.

The response of captive rodents to the migration of Ancylostoma caninum larvae.

The distribution of the larvae of Ancylostoma caninum in tissues of captive wild rodents (Rattus rattus) and the leucocytic and behavioural responses of these rodents were studied after experimental oral infection. There was a wide distribution of larvae in tissues with a preponderance of the larvae in the skeletal muscles of the anterior part of the body in older infection. The rats responded by an elevation of total leucocytes and eosinophils in blood, alternation of locomotory activity and behavioural dominance that may have a correlation with predation and epidemiology of A.

The effects of the combined administration of beta-adrenoceptor antagonists and non-steroidal anti-inflammatory drugs on ligation-induced arrhythmias in rats.

Pretreatment of anaesthetized rats with intravenously administered beta-adrenoceptor antagonists or non-steroidal anti-inflammatory drugs (NSAIDs) reduced the incidence and severity of ventricular arrhythmia which resulted from acute coronary artery ligation. The beta-adrenoceptor antagonists preferentially suppressed the immediate (Phase 1A) arrhythmia while the NSAIDs suppressed the delayed (Phase 1B) arrhythmias. Combined administration of beta-adrenoceptor antagonists and the NSAIDs produced a more pronounced antiarrhythmic effect than either of the drugs alone.

The effects of verapamil, prenylamine, flunarizine and cinnarizine on coronary artery occlusion-induced arrhythmias in anaesthetized rats.

In male rats, anaesthetized with pentobarbitone, ligation of the main left coronary artery causes an early phase of ventricular arrhythmias which last about 30 min. In approximately 60% of control animals, ventricular fibrillation occurs but since spontaneous reversion to sinus rhythm may occur, mortality is of the order of 30%. When administered intravenously 15 min prior to ligation, verapamil (0.

Antiarrhythmic actions of meptazinol, a partial agonist at opiate receptors, in acute myocardial ischaemia.

1 The intravenous administration, to anaesthetized rats, of meptazinol (1 and 2 mg kg-1), a partial agonist at opiate receptors, greatly reduced the incidence of ventricular extrasystoles that resulted from acute coronary artery occlusion. The incidence of ventricular fibrillation (VF) was reduced from 50% (in the controls) to 10% and the mortality from 30% to zero. 2 In similar doses, pretreatment with meptazinol also reduced ventricular arrhythmias, including fibrillation, in conscious rats subjected to coronary artery occlusion.
