EDX-SEM-XRF data from selected Precambrian Basement Complex rock samples in part of Southwestern Nigeria.

ABSTRACT: Energy Dispersive X-ray Analysis, EDX mapping, Scanning Electron Microscope, SEM, together with X-ray Fluorescence Analysis, XRF, was carried out to extract the needed data from some metamorphic rock samples in part of the Nigerian Southwestern Precambrian Basement Complex, NSPBC. The foremost aim is to obtain the detail subsurface geological structures of the rocks within the area and to enhanced understanding of the processes and the types of metamorphic evolution in the area. The techniques involved qualitative and quantitative data analysis of the major, minor and radioactive elements present in the samples of rocks analyzed. The data helped to experimentally evaluate the rocks microstructures, and to also explore the development of magmatic and metamorphic mechanisms for the recognition of textual associations in the area. Applications of the EDX, SEM, and XRF data analysis are effortlessly done to determine the varied mixtures of Si, Al, Ca, Fe, K, Mg, and Na, in the presence of O existing in the rocks samples.The data helped in the classification and perceptive of these rocks and it was considered as a necessary tool in the knowledge of the metamorphism and origin of the Basement Complex rocks through measurement of the intensity of the emitted X-ray and its characteristics.

Project description:BACKGROUND:The growing number of people living with life-limiting illness is a global health concern. This study therefore aimed to explore the involvement of pharmacists in selected tertiary hospitals in Nigeria in palliative care (PC). It also sought to evaluate their knowledge and attitude to PC as well as factors that hinder pharmacists' participation in PC. METHOD:Questionnaire-guided survey among pharmacists working in three-tertiary hospitals in southwestern Nigeria. The self-administered questionnaire comprised 18-item general knowledge questions related to PC, attitude statements with 5-point Likert-scale options and question-items that clarify extent of involvement in PC and barriers to participation. Overall score by pharmacists in the knowledge and attitude domains developed for the purpose of this study was assigned into binary categories of "adequate" and "inadequate" knowledge (score?>?75% versus?75%), as well as "positive" and "negative" attitude (ranked score?>?75% versus?75%), respectively. Descriptive statistics, Mann-Whitney-U and Kruskal-Wallis tests were used for analysis at p?<?0.05. RESULTS:All the 110 pharmacists enrolled responded to the questionnaire, given a response rate of 100%. Overall, our study showed that 23(21.1%) had adequate general knowledge in PC, while 14(12.8%) demonstrated positive attitude, with 45(41.3%) who enjoyed working in PC. Counselling on therapy adherence (100;90.9%) was the most frequently engaged activity by pharmacists; attending clinical meetings to advise health team members (45;40.9%) and giving educational sessions (47;42.7%) were largely cited as occasionally performed duties, while patient home visit was mostly cited (60;54.5%) as a duty not done at all. Pharmacists' unawareness of their need in PC (86;79.6%) was a major factor hindering participation, while pharmacists with PC training significantly felt more relaxed around people receiving PC compared to those without training (p?=?0.003). CONCLUSION:Hospital pharmacists in selected tertiary care institutions demonstrate inadequate knowledge, as well as negative attitude towards PC. Also, extent of involvement in core PC service is generally low, with pharmacists' unawareness of their need in PC constituting a major barrier. Thus, a need for inclusion of PC concept into pharmacy education curriculum, while mandatory professional development programme for pharmacists should also incorporate aspects detailing fundamental principles of PC, in order to bridge the knowledge and practice gaps.

Project description:Antibiotic resistance genes [ARGs] in aquatic systems have drawn increasing attention they could be transferred horizontally to pathogenic bacteria. Water treatment plants (WTPs) are intended to provide quality and widely available water to the local populace they serve. However, WTPs in developing countries may not be dependable for clean water and they could serve as points of dissemination for antibiotic resistant bacteria. Only a few studies have investigated the occurrence of ARGs among these bacteria including tetracycline resistance genes in water distribution systems in Nigeria.Multi-drug resistant (MDR) bacteria, including resistance to tetracycline, were isolated from treated and untreated water distribution systems in southwest Nigeria. MDR bacteria were resistant to >3 classes of antibiotics based on break-point assays. Isolates were characterized using partial 16S rDNA sequencing and PCR assays for six tetracycline-resistance genes. Plasmid conjugation was evaluated using E. coli strain DH5? as the recipient strain.Out of the 105 bacteria, 85 (81 %) and 20 (19 %) were Gram- negative or Gram- positive, respectively. Twenty-nine isolates carried at least one of the targeted tetracycline resistance genes including strains of Aeromonas, Alcaligenes, Bacillus, Klebsiella, Leucobacter, Morganella, Proteus and a sequence matching a previously uncultured bacteria. Tet(A) was the most prevalent (16/29) followed by tet(E) (4/29) and tet30 (2/29). Tet(O) was not detected in any of the isolates. Tet(A) was mostly found with Alcaligenes strains (9/10) and a combination of more than one resistance gene was observed only amongst Alcaligenes strains [tet(A)?+?tet30 (2/10), tet(A)?+?tet(E) (3/10), tet(E)?+?tet(M) (1/10), tet(E)?+?tet30 (1/10)]. Tet(A) was transferred by conjugation for five Alcaligenes and two E. coli isolates.This study found a high prevalence of plasmid-encoded tet(A) among Alcaligenes isolates, raising the possibility that this strain could shuttle resistance plasmids to pathogenic bacteria.
