Authors: Adebagbo Adebowale , Ojo Lucas , Ojewunmi Ola-Michael
Published: October 2022

Digital technology is redefining teaching-learning engagements and challenging the professional teachers to match the advancement; such is integration of augmented reality (AR) in education. Apparently, change often encounters reluctance to embrace it. As a lot of teachers still battle phobia for computer technologies, the integration of sophisticated AR could be a problem. No matter the challenges, reliable data could assist in planning towards mitigating the problems. Pertinently, self-efficacy data on teachers as stake holders are relevant to assist in planning, to maximise innovative potentials of AR in teaching and learning. Therefore, this study investigated teachers' self-efficacy on integration of augmented reality in teaching-learning activities among selected schools in Nigeria. In this descriptive survey research, cluster and random sampling methods were used to select sample. The target population was all the secondary school teachers in Lagos state, Nigeria; the sample comprised 178 participants. Validated Teacher Self-efficacy Questionnaire (TSQ) on 4-Likert scale, of 0.89 reliability coefficient, was used to collect data. The data were computed using percentage, bar-charts and Chi-square. The results revealed that differences in the levels of self-efficacy are not enough to make the teachers in public schools perform differently when compared to counterparts in private schools, if AR is integrated into teaching methods. Based on the results, it was recommended that awareness seminars should be organised for the teachers on how to use AR technology in education. Moreover, to ensure sustainability, require software should be made available, and the teachers should be given competency based training to use it.

Introdução: A esquistossomose é uma doença caracterizada como uma infecção parasitária, desencadeada por trematódeos pertencentes ao gênero Schistosoma mansoni, que envolve aspectos sociais, econômicos, culturais e políticos que precisa ser vista como um problema coletivo. Objetivo: descrever o perfil epidemiológico da esquistossomose na cidade de Nazaré, no período de 2007-2017. Metodologia: uma pesquisa com abordagem quantitativa, de cunho epidemiológico, transversal com abordagem descritiva. O estudo foi desenvolvido a partir de dados secundários, obtidos através do SINAN, SISPCE, PCE e divulgados na plataforma eletrônica do Departamento de Informática do Sistema Único de Saúde (DATASUS) da cidade de Nazaré-Bahia. Resultados: a cidade de Nazaré apresentou o maior número de casos notificados na Bahia durante esse período, de 2007 a 2017. A maior predominância foi do sexo masculino com 54,21%, entre 20-39 anos (41,11%), pessoas com baixa escolaridade (25,92%) e de raça parda (88,64%). Mesmo havendo um decréscimo ao longo dos anos, as taxas para lixo a céu aberto, falta de abastecimento adequado de água, e tratamento de esgoto ainda são grandes. Conclusão: A cidade de Nazaré apresenta uma baixa taxa de saneamento básico e é margeada por um rio, fatores que contribuem para elevadas taxas dessa patologia. Melhores medidas de saneamento básico são necessárias principalmente para educar a população, além de maiores investimentos em melhorar as políticas públicas. Uma atualização dos sistemas de alimentação dos dados epidemiológicos também ajudaria na caracterização de um perfil epidemiológico melhor desenhado.

Abstarct Bledug Kuwu is one of the mud volcano (gunung lumpur) in Java. Bledug Kuwu eruption periodically occured with a frequency of more than five times in one minute, pointed by the release of gas bubbles and mud. This study aims to observe the signals of the seismic and self potential (SP) from seismoelectric phenomenon generated by Bledug Kuwu eruption. Measurements were performed by placed seismic sensor around the main crater point of Bledug Kuwu mud volcano, while the SP sensor placed in the vertical, the radial and tangential direction from the point of the main crater of a Bledug Kuwu mud volcano.. The result of analysis shows that the dominant frequency of seismic events is 0,2 Hz, while dominant frequency of  SP signals is 48,0 Hz. The arrival time difference between seismic and SP signals predominantly in the range of time (0,0 to 1,5 second) which indicates that the appears of the seismic signal causes the appearance of the signal SP as a result of the transfer fluid as described in the seismoelectric phenomenon.The average value of the amplitude of seismic events for Z, NS and EW component is 0,6694, 0,4848 and 0,5158 Count/Volt. The average value of the amplitude of SP events for Z, NS and EW component is 1,338, 1,249 and 0,909 mVolt. SP events will appear if amplitude of seismic events more than 0,2 Count value. Amplitude of sesmic events proportional to the amplitude of the SP event with value of the correlation coefficient between the both is more than 80.0%, the seismic events caused the material in its path have excessive pressure that pore fluid in the material move and cause the separation of charge is the source of the appear of SP signal, the greater the amplitude of the seismic event the pressure exerted on the material so that the larger the amplitude of the SP events formed also getting bigger, this is in accordance with the theory of the seismoelectric phenomenon by electrokinetic effect mechanismKeyword: Bledug Kuwu, Self Potential (SP), seismic, dominant frequency, different arrival time, amplitude and seismoelectric effect.

O E-BOOK “EPIDEMIOLOGIA, DIAGNÓSTICO E INTERVENÇÃO EM SAÚDE PÚBLICA” através de pesquisas científicas aborda em seus 17 capítulos o conhecimento multidisciplinar que compõe essa grande área da saúde pública em diversas modalidades. Almeja-se que a leitura deste e-book possa incentivar o desenvolvimento de estratégias de atuação coletiva e educacional. A Saúde, enquanto estado vital, setor de produção e campo do saber, está articulada à estrutura da sociedade através das suas instâncias econômica e político-ideológica, possuindo, portanto, uma historicidade. As ações de saúde (promoção, proteção, recuperação, reabilitação) constituem uma prática social e trazem consigo as influências do relacionamento dos grupos sociais. Na América Latina, e no Brasil em particular, realiza-se nas duas últimas décadas um trabalho de construção de novas teorias, enfoques e métodos da epidemiologia e da planificação em saúde, além de investigações concretas buscando a aplicação de métodos das ciências sociais no campo da saúde coletiva. Desse esforço de reconstrução teórica, tem emergido no campo novos objetos de conhecimento e de intervenção, como por exemplo os casos da comunicação social em saúde e da vigilância em saúde. Nesse aspecto, cabe referir o desenvolvimento científico e tecnológico do campo mediante importantes contribuições nas áreas de Epidemiologia Social, Políticas e Práticas de Saúde, Planificação em Saúde, e Epistemologia e Metodologia em Saúde. A epidemiologia é uma disciplina básica da saúde pública voltada para a compreensão do processo saúde-doença no âmbito de populações, aspecto que a diferencia da clínica, que tem por objetivo o estudo desse mesmo processo, mas em termos individuais. Como ciência, a epidemiologia fundamenta-se no raciocínio causal; já como disciplina da saúde pública, preocupa-se com o desenvolvimento de estratégias para as ações voltadas para a proteção e promoção da saúde da comunidade. A epidemiologia constitui também instrumento para o desenvolvimento de políticas no setor da saúde. Sua aplicação neste caso deve levar em conta o conhecimento disponível, adequando-o às realidades locais. s

Pasca diundangkannya Undang-Undang Nomor 3 Tahun 2022 tentang Ibu Kota Negara berimplikasi terhadap sistem pemerintahan daerah. Hal ini merupakan konsekuensi logis pengaturan a quo yang mendesaian Otorita Ibu Kota Nusantara dengan sifat khusus dan segala kewenangan yang melekat pada badan tersebut. Sistem pemerintahan daerah yang baru tentunya menuai pro dan kontra karena dianggap inkonstitusional dan konsep pemerintahan daerah yang ambigu. Kendati demikian, dalam tataran politik hukum sebenarnya pembentukan Badan Otorita Ibu Kota Nusantara merupakan manifestasi dari Pasal 18B ayat (1) UUD NRI 1945 yang secara tegas menyatakan bahwa negara mengakui dan menghormati satuan pemerintahan daerah yang bersifat khusus dan istimewa.

Ketentuan Pasal 5C Undang-Undang No. 17 Tahun 2022 tentang Provinsi Sumatra Barat memuat Adat Basandi Syarak - Syarak Basandi Kitabullah sebagai filosofi adat Minangkabau. Namun penetapan filosofi adat Minangkabau tersebut belum memiliki tolok ukur yang jelas, sehingga dikhawatirkan membuat politik hukum pemerintah daerah Sumatra Barat terkesan memihak satu kelompok tertentu. Filosofi adat yang bersendikan syarak dikhawatirkan akan membentuk perda berbasis syariah. Selain itu, filosofi tersebut menjurus kepada satu adat yakni Minangkabau sehingga mempertanyakan bagaimana kedudukan Mentawai di Sumatra Barat yang bukan masyarakat adat Minangkabau.

Published: October 2022

Field experiments were conducted from July to November during the 2012 and 2013 cropping seasons, at the Research Farm, University of Agriculture, Makurdi, Nigeria, to evaluate the yields of two newly introduced sesame varieties (Ex Sudan and SN 603) against the commonly grown variety “E-8” under intercropping with maize variety ‘Oba 98’. The trial area consisted of a total of seven treatments, replicated three times in a randomized complete block design. The results showed that, though maize yield was not significantly (P ≤ 0.05) affected by intercropping with sesame varieties, however, intercropped yield of sesame variety ‘Ex Sudan’ was significantly (P ≤ 0.05) greater by 26.8 % and 25.6 % respectively, in years 2012 and 2013, compared to that obtained from intercropped sesame variety ‘SN 603’, and by 19.5 % and 20.9 % respectively, in years 2012 and 2013, compared to that produced from intercropped popular sesame variety ‘E-8’. Intercropping maize variety ‘Oba 98’ with sesame variety ‘Ex Sudan’ gave the highest total intercrop yield, greatest biological efficiency with a relative yield total values of 0.87 and 0.91 respectively, in 2012 and 2013. The combination also recorded the highest land equivalent ratio (LER), highest land equivalent coefficient, highest area x time equivalent ratio (ATER), highest total monetary returns (N584,200 and N588,600 respectively, in years 2012 and 2013) and highest monetary equivalent ratio (MER). The implication of study showed that sesame variety ‘Ex Sudan’ performed best and could therefore be recommended as a potential replacement for the popular variety ‘E-8’ under intercropping with maize variety ‘Oba 98’ in Makurdi, Nigeria.

The trees of parks and gardens support many species, the survival of urban-dwelling species mainly bird species. Birds amongst other species provide a wide range of environmental and social functions to cities and urban dwellers. The present study aims to know bird diversity in two parks as bioindicator of automobile air pollution exposure, landscape changes and/or human interactions. The study areas were selected as per heavily-populated neighborhoods, nearby office buildings, nearby roads and continuous vehicular movements, human interactions as visitors, where high levels of human disturbance are common. The study was carried out at 2 sampling stations viz (i) Elliot park and (ii) Agri-horticulture Society. The bird species diversity was studied by qualitative and quantitative assessment. Indices were Species richness, Index of Dominance, Relative abundance, Shannon-Wiener Diversity Index and Evenness Index for birds for all selected sites were calculated using the statistical formulae. The present results as bioindicators bird species clearly indicate that the bird species are very few in numbers in both the parks. When comparison made between both the parks, it was observed less number of bird varieties (16 types) in Elliot park than varieties (9 types) more less in number in Agri-horticulture society. This study is a preliminary assessment of bird diversity but further researches are needed in relation to biochemical and genetic damage study as well as air pollution load by using instruments. In the present study it was concluded that the less numbers of birds and their different diversity indices were found a decreasing trends, though there no attempt has been made on physico-chemical properties of present air pollutants. The less number of varieties of bird species are as tolerant bioindicators, which may be due to the vehicular pollution and/or human interference and/or landscape changes due to nearby neighborhood blocks, office and residential buildings, continuous movement of vehicles etc

Published: October 2022

It is postulated that the presence of nypa palm (Nypa palm) in mangrove forest affect the reproductive function of fish by inhibiting the growth of macro invertebrates. The impact of Nypa fruticans (Wurmb) and mangroves on the benthic macro invertebrate community of Andoni River was carried out between January and August, 2017. A total of four stations were chosen based on nypa palm and native mangrove species’ presence and absence, station 1 (Open water), Station 2 (Nypa palm dominance), station 3 (Rhizophora and Avicennia dominance), Station 4 (Mixed). Results of water quality parameters include; pH 6.99±0.16, Temperature 28.20±0.05°C, DO 4.71±0.18mg/L, Conductivity 19.52±0.20µm/s, Salinity 10.76±0.07ppt, TDS 13.45±0.27ppt. Mean values of the physico-chemical parameters (P > 0.05) were not significantly different. Twelve taxa of benthic macro-invertebrates in eleven families were collected. The crustaceans were more in diversity (38.46%), while bivalvia, pisces and oligochaete had the least percentage composition (7.69%). The gastropods were more in species dominance (44.69%), while the Oligochaeta were least in abundance (0.61%). Shannon Weiner’s index across the stations for benthos was highest in station 2 (1.840) and lowest in station 1 (1.103). Simpson’s index was highest in station 2 (1.990) and lowest in station 1 (1.938). Pielou’s index of evenness was highest in station 2 (0.767) and lowest in station 1 (0.616). All the macro-invertebrates recorded were clean water and pollution tolerant species, and showed no significant difference across stations (P>0.05). In conclusion this study indicates that nypa palm does not affect the proliferation of macro invertebrates, which supports fishery population along the food chain.

Introduction:The procedure of in-vitro fertilization (IVF) is sometime physically stressful and emotional turmoil on the couples undergoing treatment. The male partner is obliged to produce semen for injection/insemination with the oocytes. Unfortunately, some men are ill-fated, not capable to reproduce semen on the day of oocyte pickup.Objective: To testify four cases of unexpected ejaculation malfunction on the day of oocyte pickup.Setting: Base Fertility Medical Science Pvt Ltd.Materials and method: The case retrospectively reviewed the case records of four couples over a year period (September 2013–November 2014), who suffered unexpected ejaculation complete failure on the day of oocyte pickup for IVF/ICSI. Data, including age, Stimulation Protocol, cause(s) of infertility, previous treatment history (If Any) and various techniques implemented to retrieve sperms were documented.Results: Altogether, 362 oocyte pickup cycles were conducted during a year period. Four men had ejaculatory failure, providing an incidence factor of 1.10 %. Three cases (75%) had no earlier symptom/history of complexity in producing semen on requirement. Even Recommendation of 50 mg Vardenafil /Sildenafil citrate and the couples watching sexually stimulating videos did not remedy the situation. Surgical sperm retrieval was successful in case 1. It yielded no live sperm sample in case 2. Cases 3 and 4 had repeat IVF cycles. The male partners were not aware that oocyte retrieval would take place the next day and produced semen within a couple of hours.Conclusion: Anxiety and psychogenic stress most likely played a major role in these reported cases.Key: It is hoped that liquid nitrogen for cryopreservation would be the more readily available and easy technique to adopt in such scenarios to be followed for the centres for semen cryopreservation as a necessary prestep towards helping such couples and the upcoming techniques’ not widely in practice in developing countries ,oocyte vitrification*.Index Term: Semen Cryopreservation, Ejaculation Malfunction, IVF, ICSI & Stimulants.

Published: October 2022

At present, probiotic bacteria are proposed as an important alternative for antibiotic elimination and for providing renewable products through biological control in cultivation systems of marine fish larvae. The aim of this study is to compare the effects of native and commercial probiotics on growth parameters of Persian sturgeon (Acipenser persicus) larvae fed with controlled biomar diet. Experimental diets with three probiotic bacterial mixture including commercial lactobacillus (L. plantarum and L. rhamnosus), commercial Bacillus (B. subtillis and B. licheniformis) and Bacillus isolated from intestine of Persian sturgeon (B. mycoides) were completed in two levels (6.1 and 7.2 log CFU in each g of feed) and were fed to larvae of Persian sturgeon in six experimental treatments. The control treatment was fed with diet without supplementation. The experiment was done in randomized design. In all the treatments, feed conversion index was increased considerably and had significant difference with control treatment and in all the experimental treatments influenced by probiotics were higher than that of control treatment (P<0.05). The highest rate means of special growth (1.84±0.21%) and thermal growth index (3.44±0.37%) was obtained respectively in treatment C1 and C2 (isolated from intestine). Maximum special growth rate (SGR %) were obtained from C1 (4.69±0.71%) and B2 (4.62±0.87%, commercial Bacillus). In addition, native probiotic bacteria had better performance than the non native commercial species as well as selection of suitable probiotic (natural) with respect to fish species, region and condition of culture plays a special importance role in enhancing the yield of Persian sturgeon larvae.

Published: October 2022

India has a long tradition of mangrove forest management. The Sundarbans mangroves, located in the Bay of Bengal (partly in India and partly in Bangladesh), were the first mangroves in the world to be put under scientific management. The area's first management plan was implemented in 1892. Recognizing the importance of mangroves, the Government of India set up the National Mangrove Committee in the Ministry of Environment and Forests in 1976 to advise the government about mangrove conservation and development. In its first meeting, the panel, which consists of scientists, research scholars and experts on the mangrove ecosystem, emphasized the need to conduct a survey of the extent of existing mangrove areas within the country.

Published: October 2022

It has been investigated the ecological status of the cooling pond of Zaporizhzhya Nuclear Power Plant (NPP) on the hydrochemical and toxicological indicators. The ecological water quality by most hydrochemical and hydrophysical indices corresponds to the class II, category 3, and is characterized as "fairly clean". However, according to the BOD5 index, the water quality is "satisfactory" (class III, category 4). By the contents of both nitrogen of nitrates and phosphorus of phosphates the water quality belongs to the class IV, category 6, as "bad, dirty water". The main anthropogenic pollutants are copper, iron, zinc, and fluorides. The ecological characteristics by their concentrations in the water correspond to the class III, and categories 4–5 of quality, which are "poorly and moderately polluted" water. Accumulation of toxic metals in the surface layer of the reservoir bottom sediments depends on their types, the minimal content is found in sandy sediments, and maximal one is in muddy sediments. The possibility of significant secondary pollution of the water environment by toxic metals is small under the hydrophysical and hydrochemical conditions typical for the cooling pond of Zaporizhzhya NPP. According to the calculations, the value of the average chemical index of ecological quality is "2.5", which characterizes the water of the Zaporizhzhya NPP cooling pond as "good" and "clean".

The nutritional effects of marine food have increased far and wide due to the beneficial effects of consuming marine food, fats and oils. In general, the proximate composition is well known as a proportion composition of basic elements such as protein, lipids, carbohydrate, minerals and water. The puffer fish Lagocephalus lunaris and Lagocephalus inermis were collected at Mudasal odai fish landing centre and the skin and visceral organs like gonads and intestines were removed the edible portion only took for the analysis. Species of the fish sample was oven-dried in an electric oven at between 70 – 80 °C until the samples had constant weight. The protein, carbohydrate, fat, ash and moisture content of green -rough-back puffer fish and smooth-backed blow fish were investigated. L. lunaris and L. inermis were has 9.22 %, 8.92 %, 1.96 %, 1.87 %, 11.25 %, 11.98 %, 80.32 %, 86.05 %, 0.96 %, 1.27 % respectively. Totally seven saturated fatty acids; ten Mono unsaturated fatty acids and two poly unsaturated fatty acids were found as the major components on the investigated puffer fish. Polyunsaturated fatty acid like n-3 has 31.17 %, 31.19 and n-6 7.26 %, 7.29 % of PUSFA found as the dominant composition on puffer fish. This study revealed that these species are having high saturated fatty acid and protein content and able to compete with more commercially utilize species in terms of nutritional value, and they can definitely also compete when it comes to taste. It can act as a good source of nutritional and economic value when it is carefully handled and properly cooked.

Authors: Adeyeye Emmanuel Ilesanmi
Published: October 2022

This article reports the amino acid profiles of the innards of the male and female dry samples of N. maculatus collected from the Atlantic Ocean at Orimedu beach in Ibeju-Lekki, Lagos, Nigeria. The analytical results showed high values of amino acids being observed in both heterosexual samples (g 100g-1 protein): 8.17-8.32 (Leu), 8.35-10.3 (Asp), 17.6-18.2 (Glu) and 7.76-9.55 (Arg) with total amino acid values being greater in female innards (97.6g100g-1) than the male innards (95.5g 100g-1). These quality parameters were instructive of the quality of the amino acids in the innards of N. maculatus: P-PER1, (2.83-3.01), P-PER2 (2.89-2.96), EAAI (88.7-89.0), BV (85.0-85.5), Lys/Trp (L/T) (3.00-5.01), Met/Trp (M/T) (1.78-3.50) and Phe/Tyr (1.04-1.65). The pI values were close at 5.46-5.57. In the amino acid groups (classes), the following trend was observed: class I > IV >V > VI > II > III > VII. For the amino acid scores: serine (0.487-0.511) was limiting in both samples on the total hen’s egg scoring pattern; in provisional scoring pattern, Lys was limiting in both samples with values of 0.820-0.889 and in the pre-school amino acid requirements, Lys was also limiting at 0.778-0.843. In the statistical analyses total amino acid profiles as well as egg scores were significantly different between the two samples whereas quality scores in pre-school amino acid requirements and provisional amino acid scoring pattern were both not significantly different between the two samples all at r=0.01. Among the EAAs, six out of nine (66.7%) were more concentrated in the male innards and three of nine (33.3%) were more concentrated in the female. Thus the overall summary showed the male innards amino acids were of better quality than in the female as shown: male innards EEA = 46.1 g100g-1 and 46.0 g100g-1 in the female with corresponding TNEAA of 49.3g 100g-1 and 51.6g 100g-1 respectively.
Assessment of Physico-Chemical Properties of Sediments Collected along the Mahul Creek near Mumbai, India

The present study was performed for the period of one year from January 2013 to December 2013 in order to understand the physico-chemical properties of sediments samples collected along the Mahul Creek of Mumbai. The annual average pH value of the creek sediments was recorded as 5.38. It is feared that such low pH value of sediment might increase the acidity of creek water thereby triggering the heavy metal toxicity which will further reduced survivorship in fish through chronic stress and affect the reproductive partner. The annual average salinity content of the sediment was recorded as 4601.17 ppm. It is important here to note that the high salinity of the sediment may increase the salinity level of creek water which is considered as a major stress factor for most freshwater organisms including crustaceans. The average annual concentration of phosphate in the creek sediment was found to 480.39 ppm. Such high concentration of phosphate in the creek sediments might accelerate the process of eutrophication. From the results it appears that as India moves towards stricter regulation of industrial effluents to control water pollution, greater efforts are required to reduce the risk due to the toxic pollutants which are released into the ecosystems.

In this study, total phenolic, flavonoid contents, antioxidant capacity, and phenolic compositions of Castanopsis phuthoensis and Castanopsis grandicicatricata (Fagaceae family) were investigated. It was found that bark extracts were rich of phenolic contents, whereas leaf extracts were abundant of flavonoids. The total phenolics varied from 11.20 to 35.47 mg gallic acid equivalent g-1 dry weight (DW), and the total flavonoids were from 2.24 to 12.55 mg rutin equivalent g-1 DW. The results of antioxidant activity showed that the DPPH (1,1-diphenyl-2-picryl-hydrazyl) radical scavenging activity of the free phenolic extracts were higher than the bound phenolic extracts. Regarding the reducing power and β-carotene bleaching assays, the free phenolic extracts showed remarkably strong antioxidant capacity that were similar to the levels of the standard BHT (dibutyl hydroxytoluene) did. It could be concluded that free phenolic extracts were more effective in antioxidant activities than bound phenolic extracts. A highly significant correlation between phenolic contents and antioxidant activity in extracts were observed. By HPLC analysis, seven phenolic acids were detected including gallic, p-hydroxybenzoic, vanillic, sinapic, p-coumaric, ellagic, and vanillin. Of which, gallic, ellagic, and sinapic acids were the most abundant compounds in the two species. The results suggest C. phuthoensis and C. grandicicatricata contain rich sources of natural antioxidants and phenolic compounds which are probably considered in pharmaceutical use.

Plant growth and physiological response of sesame (Sesamum indicum L.) were studied in controlled environment using normal soil and indigenous Vesicular-arbuscular mycorrhiza (VAM) fungi treated soil. The seedlings of Zea mays were inoculated with Giguspora species of VAM (Glomus fasiculatum) and the inoculum was multiplied with help of Zeamays seed bed. Sesame seeds were then inoculated into the bed and it was found that the plant height, shoots lengths, roots, biomass of shoot and roots were considerably increased in the mycorrhizal plants. The effect of VAM infection was assessed in pot experiment. In this comparative study, specific mycorrhizal fungi had consistent effects on various growth parameters such as the number of leaves, number of roots, shoot length, biomass of shoot and roots and biochemical parameters were observed at various time intervals by statistical analysis using two way ANOVA, it was confined with mycorrhizal and non-mycorrhizal infected plants. It was found that the ability of isolates to maintain the plant growth effectively in the case of mycorrhizal seedlings shows a maximum absorbtion of 0.77 ±0.2, shoot length is about 8.34 ±0.2, count of root and leaves are about 8.10 ±0.3, 5.6 ±0.3 respectively under mycorrhizal infection in 30days of analysis and had a positive effect on the growth at all intervals. Biochemical analysis were carried out to estimate the total chlorophyll, chrophyll A, chlorophyll B and Carotenoids contents and it was analyzed to be 9 ±0.5 mg/g, 8.3 ±0.5 mg/g, 3.6 ±0.5 mg/g, 4 ±0.3 mg/g respectively. At the 30th day of analysis for the mycorrhizal plants, it was found to be high in mycorrhizal seedlings which shows the symbiosis had improved the nutrient uptake of cultivated plants. Nevertheless G. fasiculatum was found to be the most efficient fungus and exhibited the highest levels of mycorrhizal colonization, as well as the greatest stimulation of physiological parameters.

Published: October 2022

Biotechnology has potential to enhance the production of agricultural and industrial products for achieving food security and economic development. In agriculture, biotechnology enhances the production of high yielding and disease resistance crops necessary for achieving food security and industrial development. This paper examines the constraints in the application of biotechnology research to the production of cassava in Nigeria. The study utilized primary data collected through questionnaire administration and interview from three research institutions working on cassava biotechnology in Nigeria. Findings showed that weak infrastructural facilities, poor funding, inadequate competent personnel and absence of appropriate legislation are the constraints in the application of biotechnology to cassava production in Nigeria. In addition, one out of the three research institutions has adequate and regular electricity supply through its own captive power plant while the remaining two research institutions relied more on electricity from the national grid. Inadequate funding and shortage of competent personnel were peculiar challenge confronting all the research institutions covered by the study. The study recommends improvement in electricity supply, production of more biotechnology scientists and adequate funding to enhance biotechnology research in Nigeria.
Respiratory Surveillance and Ca2+-ATPase Enzyme Activity Studies of Clarias gariepinus Exposed to Acute Toxicity of Cyanide
Authors: Oseni Kadiri
Published: October 2022

Potassium cyanide, a highly contaminating and toxic aquatic ecosystems pollutant was investigated for acute toxicity on the freshwater fish Clariasgariepinus. Its effect on the Ca2+ -ATPase activities in the liver, gills, muscle and intestinal tissues and oxygen consumption index was studied. Short-term toxicity test was carried out by static renewal bioassay test over a 96 h period using a lethal concentration (LC50) value of 0.361mg/mL. Potassium cyanide was highly toxic to the animal tested. Results reveal that normal respiratory activity (O2 consumption) of the fish was significantly affected and there was significant decreased in the Ca2+ - ATPase activities at the end of exposure periods (24, 48, 72 and 96 h). Correlation analysis reveals a strong relationship between oxygen consumption index and ATPase enzyme activity of Clariasgariepinus exposed to the toxicant. This study reflects the toxic effect of potassium cyanide to the freshwater fish, Clariasgariepinus and suggestion on the possible application of Ca2+ -ATPase activities and oxygen consumption index as possible biomarkers for early detection of cyanide poisoning in aquatic bodies.

Published: October 2022

Organic farming is a holistic production management system that promotes and enhances environmental quality including biodiversity, bio-geo-chemical cycles and soil floral and faunal activities. One of the energy resources developed during recent years are the application of organic sources such as biogas slurry, blue green algae, compost, green manure farmyard manure, vermicompost and seaweed liquid fertilizer. During decomposition, these organic manures yield many organic compounds and organic acids as well as antibiotic substances as an intermediate product. Mangrove/Halophytes forest has an important ecological and socio economic value to man. In India, Tamil Nadu has a coastline of 950 km. Extensive mangrove wetlands are located in Pichavaram of Cuddalore district and Muthupet of Thanjavur district. It is reported that the nutrient values of halophytes were higher when compared to green manures (glycophytes). The objective of the present study is to highlight the efficacy of halophytic compost which are normally available in coastal areas on growth and yield parameters in pulse varieties. Various combinations of halophytic composts used, Suaeda compost + farmyard manure + phosphate solubilising bacteria treatment showed an increased in biomass and yield, number of root nodules and microbial activities when compared other halophytic compost and control. This study shows the feasibility of using halophytic composts in the coastal area to improve soil fertility and productivity.

Authors: Timofte Daniel , Ionescu Lidia , Ochiuz Lacramioara
Published: October 2022

Pancreatic cancer is one of the most severe malignant disease, with an extreme degree of lethality, considering that the survival rate at 5 years is up to 4%. In addition, a major disadvantage of this disease is the fact that the diagnosis is determined very late in the evolution of the disorder, despite the development of new technologies. In this way, the main symptoms are occurring later on, when the tumour is already locally advanced and unresectable. Up to now surgery is the only modality that can provide a greater chance of survival, but unfortunately the pancreatic resection has many unknowns and controversies around it. Moreover, the studies on endocrine pancreatic function after resection are very few and somehow controversial. In this way, in the present mini-review we will describe the most relevant experimental data regarding the post-resection pancreatogenic diabetes, the pancreatic polypeptide PP and the pancreatic glucose metabolism after resection or the glucose metabolism after partial or total pancreatectomy.

Published: October 2022

The present study deals with biomonitoring to know mollusc species as an indicator. In the present study, presence, absence and abundance of particular gastropod and bivalve species were identified in the different banks of river Ganga. The study was carried out at two experimental sites, Sodepur (Exp-1) and Khardah (Exp-2), West Bengal, India as the area exhibits a major sewage water outfall in the river compared with upstream control site, Kalyani (Cont-1) and downstream control site, Batanagar (Cont-1). The present biomonitoring shows qualitatively and quantitatively that in experimental no mollusc species were observed near the wastewater discharge area into the bank of river Ganga at Khardah while both sites of the sewage discharge area into the bank of river Ganga at Sodepur particular gastropod Bellamya sp. were observed when compared to control area. The highest variety and total nos of gastropods and bivalves (280 nos) were recorded in the upstream at Kalyani and lowest variety and total nos of only gastropods (150 nos) were recorded in the downstream at Batanagar. The present biomonitoring work was a preliminary observation to know sensitive and tolerant or accumulator mollusc species in the bank of river Ganga from a stretch of Kalyani (upstream) to Batanagar (downstream) in between urban wastewater discharge area (Sodepur and Khardah). Further researches must be relevant in relation to biomarker assessment with the physico-chemical factors and stress tolerant detoxification mechanism of particular mollusc species.
