University-business engagement franchising and geographic distance:a case study of a business leadership programme

This paper adapts a franchising perspective to generate a better understanding of geographic distance in university–business engagement. The study utilized an in-depth case study of a leadership and management development intervention, a programme specifically designed for small and medium-sized enterprise (SME) owner-managers (or directors) by the Institute for Entrepreneurship and Enterprise Development, within a well-respected institution, ranked in the top 1% of universities in the world. Unlike most studies, the research findings indicate that knowledge spillovers from university–business engagement can occur through replication in regions external to the university's locality

Comparative Study of Biochemical and Nutritional Status of Breast Cancer Patients on Chemotherapy/radiotherapy in Ibadan

A comparative study of BCA patients on chemotherapy/radiotherapy and immune booster supplements (combination of essential vitamins and minerals) with apparently healthy controls was investigated by assessing the lipid profile, hepatic transaminases (plasma AST, ALT) total bilurubin, lipid peroxidation and enzymatic and non-enzymatic antioxidant-superoxide dismutase (SOD) activity and plasma vitamins C and E respectively. There was no significant difference (p0.05) in total cholesterol, but we observed a significant increase in triglyceride level in BCA patients compared to control. Protein concentration decreased significantly (p0.05) in BCA patients, compared to control. SOD and vitamin C levels were not significantly different while vitamin E decreased significantly (p0.05) in BCA patients compared to control. Lipid peroxidation increased (p0.05) in BCA patients compared to control. We observed an increase in AST, a decrease in ALT and total proteins in BCA patients that were significant and a non-significant decrease in the bilirubin level when compared with control.The results support the fact that BCA patients on chemotherapy have altered dietary intake and the enhanced metabolism of lipids and proteins may increased oxidative stress

The effect of augmented input on the auditory comprehension of narratives for people with aphasia : a pilot investigation

Augmented input is the strategy of supplementing expressive language with visuographic images, print, gestures, or objects in the environment. The goal of augmented input is to facilitate comprehension of spoken language. The purpose of this study was to evaluate the relative effectiveness of two different augmented input conditions in facilitating auditory comprehension of narrative passages in adults with aphasia. One condition involved the communication partner (clinician) of the adult with aphasia actively pointing (AI-PP) out key content words using visuographic supports. The second condition involved no active pointing (AI-NPP) by the communication partner (i.e., attention was not drawn to the visuographic supports). All 12 participants with aphasia listened to two narratives; one in each condition. Auditory comprehension was measured by assessing participants’ accuracy in responding to 15 multiple-choice cloze-type statements related to the narratives. Of the 12 participants, seven gave more accurate responses to comprehension items in the AI-PP condition, four gave more accurate responses in the AI-NPP condition, and one scored the same in both conditions. These differences were not statistically significant (p > 0.05). Communication-partner-referenced augmented input using combined high-context and PCS symbol visuographic supports improved response accuracy for some participants. Continued research is necessary to determine partner involvement with and frequency of augmented input that improve auditory comprehension.The National Research Foundation (NRF) Thuthuka program (TTK 150708124127) and the University of Pretoria (Research Development Program).http://www.tandfonline.com/loi/iaac202020-06-07hj2019Centre for Augmentative and Alternative Communication (CAAC

New-Onset Seizures in HIV Patients on Antiretroviral Therapy at a Tertiary Centre in South-West, Nigeria

Background: Seizures are associated with neurological manifestations of HIV. They may be the presenting symptom and can occur at any disease stage. Aim: To determine the frequency and clinical aspects of new-onset seizures in patients with human immunodeficiency virus (HIV) infection. Methods: A study of an HIV-infected patient cohort on highly active anti-retroviral therapy (HAART) in the out-patients clinic of the Lagos state university teaching hospital, Nigeria. In a cross-sectional design, 308 HIV infected patients were recruited over a period of 1 year. Cases with a first seizure during this period were further examined. Details of demographic data, the first seizure date, seizure characteristics, neurologic complications and CD4 count at the time of the seizure were documented. Results: A total of 20 (6.5%) had new-onset seizures during the study period. 6/20 (30%) were males and 14/20 (70%), females. Their ages ranged between 22 - 51 years with a mean of 34.2 ± 8.7 years. The seizure was focal in 2/20 (10%) of cases and generalised in 90% (18/20) of cases. A total of 13/20 (65%) had recurrence of their seizures. None of the cases had focal neurological deficit at the time of the first seizure. The mean CD4 count was 165.3 ± 145.7. The mean duration on HAART was 19.5 ± 12.7 months. Cases with CD4 counts ≤200 cells/mm3 constituted 70% (14/20) whilst those with CD4 counts >200 made up 30% (6/20) [p = 0.666]. Conclusions: Seizures remain a significant neurological manifestation of HIV infection and has a high recurrence rate. It occurs more commonly in the advanced stage with severe immune suppression and may be attributable to HIV encephalopathy. Early treatment would reduce the burden and improve patient’s quality of life

Seroprevalence of human T lymphotropic virus antibodies among healthy blood donors at a tertiary centre in Lagos, Nigeria

Introduction: Transmission of human T-lymphotropic viruses (HTLV) occurs from mother to child, by sexual contact and blood transfusion. Presently, in most centres in Nigeria, there is no routine pre-transfusion screening for HTLV. The study aims to determine the prevalence of HTLV-1 and HTLV-2 among healthy blood donors at a tertiary centre in Lagos. Methods: A cross-sectional study was carried out at the blood donor clinic of the Lagos State University Teaching Hospital (LASUTH), Ikeja. About 5mls of venous blood was collected from each subject into a sterile plain bottle after obtaining subject's consent. The serum separated and stored at -200C. Sera were assayed for HTLV by an enzyme-linked immunoassay (ELISA) for the determination of antibodies to HTLV 1 and HTLV -2. Western blot confirmatory testing was done on reactive samples. All donors were also screened for HIV, HBsAg and HCV by rapid kits. Results: The seroprevalence of HTLV -1 by ELISA was 1.0% and 0.5% by Western Blot among blood donors. A total of 210 healthy blood donors were enrolled. Only 2 (1.0%) blood donors were repeatedly reactive with ELISA test. On confirmatory testing with Western Blot, 1 (0.5%) blood donor was positive for HTLV. All the healthy blood donors were negative for HIV, HbsAg and HCV. None of the 210 blood donors had been previously transfused; as such no association could be established between transfusion history and HTLV positivity among the blood donors. Conclusion: The seroprevalence of HTLV in this environment is low among healthy blood donors

Mean platelet volume and platelet counts in type 2 Diabetes: Mellitus on treatment and non-diabetic mellitus controls in Lagos, Nigeria

Introduction: The Mean platelet volume and platelet counts are indicators of thrombotic potentials, and risk factors for microvascular complications in diabetics. This study aimed to establish variations in platelet counts and mean platelet volume in type 2 diabetic patients on treatment and non-diabetic controls. Methods: This was an unmatched case-control study involving 200 participants consisting of 100 diabetics and 100 non-diabetic controls. Four and half milliliters of blood was collected from diabetics and non diabetic controls into EDTA anticoagulant tubes. Full blood count was performed using the Sysmex KN-21N, (manufactured by Sysmex corporation Kobe, Japan) a three- part auto analyzer able to run 19 parameters per sample including platelet counts and mean platelet volume. Results: The mean fasting blood sugar for the diabetics was 147.85±72.54 mg/dl and the controls 95.20±30.10 mg/dl. The mean platelet count for the diabetics was 235.29±76.81*109/L and controls, 211.32±66.44*109/L. The mean platelet volume, for the diabetics was 8.69±0.67 fl and the controls, 8.91±0.80 fl. There was a statistically significant difference in platelet counts of diabetics and healthy controls p =0.038 while none existed between the mean platelet volume in diabetics and healthy controls p=0.593. Conclusion: This study revealed a higher mean platelet count for diabetics on treatment than for non diabetic controls while mean platelet volume was lower in cases than controls. However, both parameters in diabetics on treatment were within the normal reference range for healthy individuals

Beyond the entrepreneur : a study of entrepreneurial learning from a social practice perspective working with scientists in West Africa

This article contributes to extending the current conceptualisation of entrepreneurial learning by challenging the assumption that entrepreneurial learning is solely embodied in the entrepreneur. Entrepreneurial learning is an emergent trend that involves a developmental approach to learning in acting on opportunities and experiences. We apply a social practice theory to entrepreneurial learning to advance understanding of the value of entrepreneurial thinking towards informal, experiential and aspirational learning. We position entrepreneurial learning within the social learning and social practice literature in the (1) alternative formats to formal learning, and (2) implications of entrepreneurial learning, as a social practice, for management learning and entrepreneurship education research. Based on a qualitative empirical analysis of a co-created entrepreneurial learning programme for ‘Stimulating Entrepreneurial Thinking in Scientists’, this study shows that entrepreneurial thinking can be expanded beyond the entrepreneur, and developed by others such as science, technology, engineering and mathematics scientists. With the drive for individuals to become entrepreneurial in their everyday practices, our study contributes towards extending the conceptualisation of entrepreneurial learning through insights from social practice theory. In addition, by understanding the value of entrepreneurial thinking, particularly via non-formal and informal approaches to learning, our research expands underexposed issues of entrepreneurial learning across diverse audiences, contexts and disciplines

Curcuphenol possesses an unusual histone deacetylase enhancing activity that counters immune escape in metastatic tumours

Curcuphenol, a common component of the culinary spices, naturally found in marine invertebrates and plants, has been identified as a novel candidate for reversing immune escape by restoring expression of the antigen presentation machinery (APM) in invasive cancers, thereby resurrecting the immune recognition of metastatic tumours. Two synthetic curcuphenol analogues, were prepared by informed design that demonstrated consistent induction of APM expression in metastatic prostate and lung carcinoma cells. Both analogues were subsequently found to possess a previously undescribed histone deacetylase (HDAC)-enhancing activity. Remarkably, the H3K27ac ChIPseq analysis of curcuphenol-treated cells reveals that the induced epigenomic marks closely resemble the changes in genome-wide pattern observed with interferon-γ, a cytokine instrumental for orchestrating innate and adaptive immunity. These observations link dietary components to modifying epigenetic programs that modulate gene expression guiding poised immunity

Preterm birth: inflammation, fetal injury and treatment strategies

Preterm birth (PTB) is the leading cause of childhood mortality in children under 5 and accounts for approximately 11% of births worldwide. Premature babies are at risk of a number of health complications, notably cerebral palsy, but also respiratory and gastrointestinal disorders. Preterm deliveries can be medically indicated/elective procedures or they can occur spontaneously. Spontaneous PTB is commonly associated with intrauterine infection/inflammation. The presence of inflammatory mediators in utero has been associated with fetal injury, particularly affecting the fetal lungs and brain. This review will outline (i) the role of inflammation in term and PTB, (ii) the effect infection/inflammation has on fetal development and (iii) recent strategies to target PTB. Further research is urgently required to develop effective methods for the prevention and treatment of PTB and above all, to reduce fetal injury
