An assessment of the quality of some portable water obtained within enugu metropolis

Provision of clean water is one of the United Nations Sustainable Development Goals. Water quality assessment as an ongoing exercise, in view of the threat of contamination from natural sources and human activities, plays a pivotal role in the sustainable management of water resources. Potable water samples were collected from Enugu Metropolis for water quality assessment. The physicochemical parameters were determined using APHA (1995 - 1998) protocols, and the presence of 7 heavy metals (Chromium, Zinc, Manganese, Silver, Cadmium, Iron and Lead) in the waters were determined using Atomic Absorption Spectrophotometer (AAS). The results of the physicochemical analysis of the four samples show a pH range of 8.60 - 8.95mg/l; this result showed that pH of the water samples were slightly alkaline and above the WHO stipulated range of 6.50 - 8.50. Acidity ranged from 5.00 - 6.88mg/l, while alkalinity values were between 7.52 - 13.00mg/l. The total dissolved solid (TDS) and total solids (TS) was present in very minute quantities and below their permissible limit of 0.45mg/l; while total suspended solid (TSS) was not present at all. The heavy metal analysis showed that all but 2 heavy metals (Cadmium and Lead) were below the permissible standard set by the WHO in all four samples. Cadmium was present in samples A and C with values 0.021mg/l and 0.006mg/l respectively, which is above its WHO limit of 0.005mg/l; while Lead was present in samples A, B and C with values of 0.021mg/l, 0.011mg/l and 0.015 mg/l respectively, which were above the WHO limit of 0.010mg/l. Given the well-documented toxicity of certain metals, there is a need for safety checks to be carried out in potable water companies to address the source of this contamination and ensure production of safer drinking water.

Ethnopharmacology- drug discovery from treasure house of ancient wisdom

Ethnopharmacology is an information exchange and understanding about people's use of plants, fungi, animals, microorganisms and minerals to discover a a wealth of helpful therapeutic agents and explore their toxic potential passed On by oral tradition or in written documented form Materia medica. This study area provides a scientific backbone for developing active therapeutics based on the traditional medicine of various ethnic groups. It is the interdisciplinary scientific exploration of biologically active agents traditionally employed or observed by man. The broad spectrum Of this domain covers social (anthropology), chemical (chemistry), biological (botany, biochemistry, microbiology) and pharmaceutical sciences (pharmacognosy, pharmacology and clinical therapeutics). Many valuable drugs of today (e.g., atropine, ephedrine, tubocurarine, digoxin and reserpine) have been used by studying indigenous remedies. Chemists continue to use plant-derived drugs (e.g., morphine, taxol, physostigmine. quinidine and emetine) as prototypes in their attempts to develop more effective and less toxic medicines. Currently, USP and BP contain many active ingredients/excipients from natural sources. Its objectives include the preservation of indigenous medical knowledge to understand the pharmacological basis Of herbal medicine; scientific study of indigenous drugs to contribute in the long run to promote or improve primary health care in regions of study; search for pharmacologically unique principles from existing indigenous remedies; finding a valid reason to guard the rainforests or to engage in conservation; establish gene banks and libraries of plant extracts for future biological evaluation: well-established germplasm banks for essential crops. Ethnopharmacology can be an innovative and powerful discovery engine for newer, safer, and more affordable medicines from the treasure house (traditional knowledge of indigenous peoples) of ancient wisdom.

Fdi in indian higher education

The decision of the government of India to allow foreign direct investment in higher education is based on a consultation paper prepared by the commerce ministry, which is marked by arguments, perverse logic and forced conclusions. FDI in any field does not have an attached objective of fulfilling social agenda of the welfare state. It is guided by profit and market. This would result in commoditization of education. As per past most foreign institutes invest in technical courses which market needs rather than in quality education and research which is important for creating and developing human resource. There is a shortage of funds in higher education sector. Here are not many ways in which this investment in this sector can be increased in this sector domestically. Since a large number of students go abroad for their higher education, it is sensible to allow foreign universities to set up their campuses here, in India. This would help in arresting the outflow of monetary and human capital. Further, foreign higher educational institutes would create competition with the local institutes making them internationally competitive this article examines the issues and financial compulsions, presented in the consultation paper

Probing the filipino college students' pragmatic competence: its pedagogical implications in language teaching and learning

The study identified the pragmatic competence level of the second language (L2) learners through Written Discourse Completion Test (WDCT) administered to purposively selected 40 first-year education students. A modified questionnaire based on Survey for Academic English Language Exposure (SAELE) was used to determine the effectiveness of academic English language exposure on the pragmatic competence development of the respondents. The study employed the descriptive-correlational method, while various statistical tools were utilized to analyze and interpret the data. Weighted mean was used to determine the respondents’ pragmatic competence level and the effectiveness of academic English language exposure on the pragmatic competence development of the respondents. Moreover, Pearson Product Moment Correlation (PPMC) was employed to determine the significant relationship between the two variables. Results in WDCT showed that the average scores in the pre-test and post-test results fall under the competent level. Meanwhile, the effectiveness of academic English language exposure on the pragmatic competence development of the respondents was 0.207, which is ineffective. Lastly, the statistical correlation of the two variables showed no significant relationship between them (r=0.046, p>0.05). Based on the study’s results, pedagogical implications for pragmatic and L2 teaching and learning were conceptualized.

Central nervous system pseudomass in neurobehçet's syndrome: a rare radiological manifestation and diagnostic challenge

Neuro-Behçet's Syndrome (NBS) is a rare yet potentially severe neurological manifestation of Behçet's disease (BD). Although the condition frequently affects the brainstem, basal ganglia, and diencephalon, [1,2] its occurrence as a mass-like lesion (pseudotumor) is exceedingly uncommon. These tumefactive lesions can resemble neoplastic, infectious, or demyelinating conditions, which often hinders prompt diagnosis and treatment. [1-3] In this report, we discuss a 56-year-old female from Libya with a history of Behçet’s disease, who presented with headaches, visual disturbances, and cognitive slowing. Magnetic Resonance Imaging (MRI) findings indicated a high T2/FLAIR signal in the bilateral basal ganglia and the left cerebellar hemisphere, extending into the middle cerebellar peduncle, accompanied by faint contrast enhancement.

A systematic review on self-reported questionnaires to assess medication adherence in diabetic patients

Adherence to pharmacological therapies are keys to effective treatments in diabetic patients. Previous reviews found that most adherence measurement studies on chronic diseases used a self-reported scale. However, there is no consensus on the best scale to measure adherence in diabetic patients. The purpose of this systematic review was to identify the potential self-reported scale that could be considered for measuring medication adherence in diabetic patients and to provide recommendations for researchers or clinicians to determine appropriate adherence self-reported scales in diabetic patients. This review follows general guidelines in the implementation of systematic reviews. After further review, it was found that 33 studies met all inclusion criteria from 4 databases (Wiley, Science Direct, Scopus, and PubMed). The articles were done by the PRISMA, while the keywords were determined by the PICO method. Most research was conducted in Asia (69.7%) and America (18.2%) on patients with type 2 diabetes (81.3%), patients in hospitals (54.5%), suffering for 1–6 months (54.5%), and using a cross-sectional study design (78.8%). HbA1c clinic data (57.6%) were used in most studies as biological markers of adherence. The measurement scales of medication adherence in diabetic patients are MMAS-8 (57,.5%), MMAS-4 (12.1%), BMQ (9%), MCQ (6%), ARMS (3%), ARMS-D (3%), GMAS (3%), LMAS-14 (3%), and MARS-5 (3%). This review provides information on the different self-reported scales most widely used in diabetic medication adherence research. Various aspects need to be considered before choosing the scale of adherence.

Vitamin c and human diseases: an overview

Vitamin C is associated with history of the cause of the ancient hemorrhagic disease scurvy. Vitamin C is an essential nutrient with important antioxidant properties. It is required by the body for normal physiological function. The body cannot synthesize vitamin C, it is present in nature through foods and other natural sources and it exists as a nutritional food supplement. The antioxidant activity of vitamin C protects the body from free radical damage. Vitamin C is essential for the development and maintenance of connective tissues. It is used as therapeutic agent in many diseases and disorders. Vitamin C plays an important role in several metabolic functions, as the conversion of the amino acid, tryptophan, to the neurotransmitter, serotonin, and the conversion of cholesterol to bile acids. Vitamin C supplementation resulted in a significant increase in vitamin C levels in populations; its high intake is associated with positive effects on cardiovascular risk factors. Vitamin C protects the immune system, reduces the severity of allergic reactions and helps to fight infections. It has an important role in bone formation, wound healing and the maintenance of healthy gums. There is profound beneficial effect of vitamin C in respect to human diseases as cancer, atherosclerosis, diabetes, neurodegenerative disease and many metal toxicities. Several vitamin C analogs have been produced as anticancer and antioxidant activity. Vitamin C is useful if it is used as adjuvant therapy for several chronic diseases. Thus, this review summarizes the importance of vitamin C in the body’s physiology and biochemistry, in addition, the different mechanisms that vitamin C is implicated to treat different acute and chronic diseases. Future exploration should pay attention to chronic disease management by vitamin C.

Use of weight-reducing products among libyans: pharmacist intervention in obesity management

Obesity is a complex and challenging global public health concern. It is a major disease involving excessive fat accumulation that may impair health. Obesity is dangerous and has been related to a range of long-term health issues that can impact adults and children. According to the World Health Organization, more than one billion people worldwide are obese as of March 2022. In the Libyan situation, the prevalence of obesity has increased among the public over the last decade. This cross-sectional survey-based study is conducted by using self-structured designed questionnaire to evaluate the use of anti-obesity drugs and herbal products among Libyan people. Additionally, considered as an indirect method, pharmacist performance in obesity management was also evaluated. The investigators collected interview data from three different cities in the Northwest of Libya over a period of five months, 2019. A total of 170 participants who use weight loss products were randomly selected to participate in the study after obtaining their verbal consent. The participants' experience with weight reduction agents revealed that more than half of the participants (52.3%) used herbal products while 32.0% of the participants have used drugs of chemical origin and 15.6% have used both (herbal and drugs). The majority of the participants (91.4%) used these products without medical consultation which in turn led to failure to lose and maintain weight with 74.2% gaining weight after stopping using these products. In conclusion, poor pharmacist intervention in obesity management was revealed where the majority of the participants reported that Libyan community pharmacists had not been offering weight management services, monitoring weight loss progress, or explaining the risks of being overweight or obese.

Ayurvedic lipid based rasayans- a perspective on the preparation and pharmacological significance of lipids on the bioavailability of phytoconstituents

For thousands of years, lipid based Ayurvedic formulations have been made in India, and the craft has survived down the millennia up to the present time. Some of these deliciously potent phytonutrient preparations are very popular and have sustained the test of time pertaining to their efficacy. Recent researches on the role of phytonutrients in promoting cardio-pulmonary, brain and immune health substantially buttress the philosophy underlying the use of lipids in preparing these emulsions, since a large number of these bioactives are lipophilic. Being lipoidic, they are absorbed through the lacteals in the small intestine, and are then transported through the thoracic duct directly to the heart, bypassing the liver. The formulations utilizing ghee (clarified butter) or sesame oil as the carrier lipid, either while frying the myrobalams or as Anupana (adjuvant), have special significance in modulating bodily immunity, since the immune system is housed in lymphatics which are lipid rich. Amla and lipid based Ayurvedic rasayans (rejuvenating formulations) are a popular and highly palatable group of phytonutraceutical preparations. This group of polyherbal adaptogenic formulations is classified separately from other formulations in Ayurvedic therapeutics. Several of these healthpromoting rasayans are suitable to be consumed by all age-groups in the recommended season and dose. Current research on endothelial and immune cell receptor mediated uptake of lipoidic molecules, together with the knowledge of lipid absorption pathways, lends credence to the usefulness of rasayans in targeting the cardio-pulmonary and immune systems. An attempt has been made in this paper to elucidate the mechanisms underpinning the complex interplay between lipid delivered hydrophobic phyto-molecules, systemic lymphatics and the Immune system.

Ecofriendly synthesis of pure and modified cumno3: it’s application as gas sensor

Recently, novel materials like gas-sensing metal oxides, mixed metal oxides, and modified mixed metal oxides have attracted great attention owing to their key roles in monitoring environmental pollution, security in hospitals, homes, and public places, and hazardous emissions from industries and automobile exhaust. Initially, the mechanochemical (MCh) method was employed for the synthesis of the CuMnO3 catalyst and then the modification of CuMnO3 through the hydrothermal route. These synthesized catalysts were characterized by Ultraviolet Violet-Diffused Reflectance (UV-DRS) spectroscopy, Fourier Transform Infrared Spectroscopy (FTIR), and Scanning Electron Microscopy (SEM). The average particle size obtained for 3 % Fe/CuMnO3 was found to be 14–28 nm. The present work proclaimed that among all the synthesized 1,3,5 % Fe/CuMnO3 materials, the 3 % Fe modified CuMnO3 material shows significant gas sensing properties towards highly toxic H2S gas released from sewage plants, oil, and natural gas industries, among NH3, CO2, H2S, H2, CO2 and Cl2 with moderate temperature requirements and excellent selectivity.
