This study determined the relationship between digital learning resources in prevocational home economics and business studies for the development of self-reliant skills. The study adopted the descriptive survey design and was conducted in Cross River State and delimited to Calabar Metropolis using a population of 160 participants that was purposively selected as respondents who were JSS 3 students using prevocational home economics and business studies. The questionnaire sought the nature of relationship based on Very High Relationship (VHR) – 5 points; High Relationship (HR) – 4 points; Low Relationship (LR) – 3 points; Negative Relationship – 2 points (NR) – 1 point. The coefficient of determination was used to answer the two research questions, while simple linear regression was used to test the two null hypotheses. Findings reveal positive and significant relationship between digital learning resources in prevocational home economics and business studies for the development of self-reliant skills. Digital learning resources possess the potency to improve learning for the acquisition of self-reliant skills, as demanded globally and for family as well national development in Nigeria. Therefore, teachers, parents, school management, agencies of government responsible for the approval of pre-TVET and TVET programmes at all levels of education should be in constant synergy for the provision of digital resources for quality service delivery.

Published: February 2024

The aim of the present work was to evaluate the potential of Clinopodium vulgare water leaves extract to decrease the DNA damaging action of zeocin and to throw more light on the mode of action.
Single and combined treatments with 10, 100, and 1000 µg/ml plant extract and 100 µg/ml zeocin were performed on 551 (haploid) and D7ts1 (diploid) yeast strains. The protective potential, the magnitude of the repair capacity, and the role of incubation conditions were studied based on double strand breaks' (DSB) induction and rejoining.
The results provided new evidence that despite the different ploidy both strains are DSBs repair proficient but differ in their repair capacity although comparable levels of initially induced DSBs were measured. The diploid strain D7ts1 was found to possess better-expressed repair capacity than the haploid strain 551. The combined treatment with Clinopodium vulgare L. extract at concentrations' range of 10—1000 µg/ml and zeocin resulted in a significant decrease in DSBs levels. It could be suggested that priming the cells with various concentrations of the extract results in an acceleration of DSBs rejoining when 30 min recovery time at optimal experimental conditions is given. When incubation is performed on ice the repair processes are impeded but not fully blocked. Such a study confirms that the difference in the repair capacity of the cells could be one of the possible mechanisms, participating in cell protection against different DNA damaging factors. The combined application of Clinopodium vulgare L. extract at concentrations range of 10—1000 µg/ml protects yeast DNA against zeocin-induced DSBs by acceleration of DSB rejoining.

Published: February 2024

Through the last decades the duration of life and the number of elderly people is rapidly growing. In this age group morbidity of epilepsy is increasing very fast. Neurophysiological methods play an important role in diagnostics, classification of the disease and the type of the seizures, and in treatment monitoring in the elderly with epilepsy. The aim of the present study was to establish the significance of neurophysiological methods for diagnostics and treatment monitoring, as well as their relation with particular clinical characteristics of the disease in elderly patients. The study group consisted of 297 consecutive patients with epilepsy (average age 69.25±5.00 years). The methods used were documentary analysis, an interview of clinical factors, EEG (basic and control), video-EEG and statistical methods. Patients with longer duration of the disease were with significant worse neurophysiological results, higher seizure frequency and more in number antiepileptic medications. Epilepsy in the elderly is a major and growing issue. The results of the study will be useful in diagnostics and treatment monitoring in this age group.

Quality of Life in Caregivers of Children with Cerebral Palsy in Rivers State, Nigeria
Authors: Gabriel-Job N  , Wobo KN  , Frank-Briggs A.I  
Published: February 2024

Introduction: Cerebral palsy (CP) is a common neurologic disorder which leads to physical disability in children. Children with CP require more care and attention from their care givers. Hence the quality of life (QoL) of the care givers can be adversely affected.
Aim: The aim of this study is to assess the QoL and its determinants among caregivers of children with CP in Port Harcourt, Nigeria.
Materials and Methods: Using a convenience sampling method, a hospital based cross-sectional descriptive study was carried out, participants were 96 caregivers of children on follow up for CP. The English Version of the World Health Organization Quality of Life-Bref (WHOQOL-Bref) was used to evaluate the QoL of the participants. A structured questionnaire was used to obtain socio-demographic characteristic of the participants and children with CP, while the patients hospital record was used to obtain the medical history of the patients. The functional disability level of the child was measured by the Gross Motor Function Classification System (GMFCS levels I-V) scale. Multiple regression analysis was carried out to determine the predictors of the care givers QoL on all four domains of the WHOQOL-Bref.
Results: The age of the participant ranged from 23 -58 years with a mean age of 37.67± 8.27 years. Seventy-eight (81.3%) were females, 77(80.0%) had secondary education and above while 56 (58.3%) of the patients had co-morbidity. The care givers had lower level of QoL < 60 points in all domains except for Physical Health Domain which had mean point of 61.3.
The GMFCS level of the patients with CP and the marital status of the caregivers significantly determined the different domains of the caregivers QoL (p ≤ 0.05). Age of care giver (p 0.00), presence of comorbidity (0.03) significantly predicted the psychological domain of the QoL of the care givers. In addition, the socioeconomic class significantly predicted the environment and psychological domains of the caregivers QoL. (p < 0.05)
Conclusion: The quality of life in caregivers of children with cerebral palsy is low. The predictors include GMFCS level of the patient, age of the care giver, marital status, presence of comorbidity and socioeconomic status. The treatment of CP should include strategies to enhance the health and quality of life of caregivers of children with the condition.

Abstract
Knowledge of electrophysiology forms the groundwork for understanding many processes in the human body, particularly the neuromuscular system. Electrodiagnostic studies are specialized tests performed by physiatrists and neurologists that are useful for diagnosing many diseases of nerve and muscle. A sound understanding of human anatomy, physiology, and physics is a requisite to understanding clinical electrodiagnosis. To illustrate how the principles of electrophysiology are applied to common diseases, a discussion of carpal tunnel syndrome is included with this review.

Published: April 2006

AbstractThis paper presents a comparative study on the electrochemical behavior of the flavonoid rutin on a rigid carbon‐polyurethane composite electrode and on a glassy carbon electrode. The electrochemical oxidation reaction of rutin was found to be quasireversible and affected by adsorption on the electrode surface. A square‐wave voltammetric method was developed for determination of rutin in green tea infusion samples using the RCPE electrode and data treatment by a deconvolution procedure. The detection limit achieved in buffered solutions was 7.1×10−9 mol L−1 using the RCPE and 1.7×10−8 mol L−1 using the GC electrode the average reproducibility for five determinations being 3.5%.
Synthesis of Enniatin‐like Cyclic Depsipeptides via ‘Direct Amide Cyclization’
Authors: Köttgen Peter , Linden Anthony , Heimgartner Heinz 
Published: April 2006

AbstractThe synthesis of several 18‐membered cyclodepsipeptides with an alternating sequence of α,α‐disubstituted α‐amino acids and α‐hydroxy acids (compounds 14a–14e) is described. The ring closure via macrolactonization was accomplished by treatment of a diluted suspension of the corresponding linear precursors 12a–12e in toluene with HCl gas, i.e., the so‐called ‘direct amide cyclization’. The incorporation of the α,α‐disubstituted α‐amino acids was achieved via the ‘azirine/oxazolone method’ with 2H‐azirin‐3‐amines of type 6 and 9 as building blocks. The structure of the cyclic depsipeptide 14a was established by X‐ray crystallography.

The use of the QNST–II as a measure for the identification of children with perceptual‐motor deficits
Authors: Parush Shula , Rilsky Artal , Goldstand Sarina , Mazor‐Karsenty Tal , Yochman Aviva 
Published: April 2006

AbstractThis study aimed to examine the ability of the Quick Neurological Screening Test–II (QNST–II) (Mutti et al., 1998) to discriminate between children with and without perceptual‐motor deficits and to further clarify its psychometric characteristics. Ninety‐four children aged six to seven years were tested on the QNST‐II. Out of this pool of subjects, 63 children had perceptual‐motor deficits and 31 were typical controls. The children with perceptual‐motor deficits scored significantly lower than the control children on the total score and on each of the subtest's scores of the QNST–II. Inter‐rater reliability indicated a high degree of correlation between both evaluators' total scores of the QNST–II. In terms of the test's sensitivity and specificity, QNST–II scores correctly classified 97% of the children with perceptual‐motor deficits and 84% of the children from the control group. The findings of this study support the capability of the QNST–II to discriminate between children with perceptual‐motor deficits and typical children; thereby suggesting its usefulness as a screening measure to identify children at risk for difficulties in school performance.

Lateral reach: a clinical measure of medio‐lateral postural stability
Authors: Brauer Sandra , Burns Yvonne , Galley Prudence 
Published: April 2006

AbstractBackground and PurposeMedio‐lateral postural instability has recently been identified as a risk factor for falls in the elderly community‐dwelling population. However, few clinical tests involve challenges to stability limits in the medio‐lateral direction. A lateral reach test was thus developed. Preliminary evaluation of the symmetry, accuracy, test–retest repeatability, and construct validity of the lateral reach test was undertaken to ensure its validity and repeatability prior to clinical application.MethodSixty healthy older female subjects (aged 72.5 ± 5 years) participated in this study which involved two tasks. The first was the clinical test: a maximal lateral reach to the right and left, recorded by a clinical measure (observation of hand excursion) and a laboratory measure (3D analysis of hand marker excursion). The second was the recording of centre of pressure (COP) stability limits in the lateral direction by use of a dual force platform system. Eighteen subjects returned for repeatability testing.ResultsNo significant differences in the measures were found between the sides. Lateral reach as measured by the clinical measure was significantly (p < 0.05) correlated with both the laboratory measure of reach (r = 0.650) and with COP stability limits (r = 0.331). The clinical measure of reach was not significantly different (p > 0.01) from the laboratory measure. High test–retest repeatability (r > 0.94) was found for all measures.ConclusionsThe clinical lateral reach test was found to be an accurate measure of lateral reach ability. As it was significantly correlated with COP excursion it was deemed a valid indicator of lateral stability limits. In addition, the lateral reach test had high test–retest repeatability and was symmetrical between the sides. These promising results support both it's use where a clinical indicator of medio‐lateral postural stability is desired and further investigation of the lateral reach test in clinical populations.

Published: April 2006

AbstractAdes and Medley provided the first flexible method for estimating age‐ and time‐specific HIV incidence using HIV prevalence data collected among pregnant women and adjusting for the effect of differential selection between infected and uninfected women. This paper extends the approach proposed by these authors. We used a parametric model that allows the relative inclusion rate to depend on both age, calendar time, and duration of HIV infection. We developed a two dimensional penalized log‐likelihood approach for estimating time‐ and age‐specific incidence using a binomial likelihood function and a quadratic roughness penalty which allows smoothing over both age and time. Identifiability of the model parameters and effect of sample size are studied through simulations. The method is illustrated using prenatal HIV testing data recorded from 1995 to 2002 in Abidjan, Côte d'Ivoire, to estimate the HIV annual incidence rate among women aged 12–40 year old, from the beginning of the epidemic to 2002. We show that estimated incidence rates are highly dependent on hypotheses made to model the relative inclusion rate. Despite this dependency, the application of the method leads to new and accurate findings on HIV incidence qualitative features in Abidjan. We highlight the relevance of such a method in monitoring the dynamics of HIV epidemic in Africa which is essential for planning vaccine trials and future treatment needs, and for assessment of prevention policy.
