  • Abstract

    Diarrhoea has been a major cause of morbidity and mortality especially among children in developing countries. Anogeissus leiocarpus (Combretaceae) has been reported to possess a number of medicinal properties. The purpose of the present study was to evaluate effects of methanolic extract of A. leiocarpus stem bark on castor oil- induced diarrhoea model in rats. Rats were divided into four groups of five in each and treated. Group I (distilled water), group II (200mg/kg extract), group III (400mg/kg) and group IV Loperamide (2mg/kg). All treatments were orally administered for effects on intestinal motility, fluid accumulation and electrolytes secretion pre and post administration of extract and their respective percentages expressed relative to experimental control. Methanol 10.67%. The preliminary phytochemical screening revealed the presence of tannins, saponins, flavonoids, terpenes, alkaloids and glycosides. 200 and 400mg/kg methanolic extract significantly (P<0.05) inhibited motility by 41.11% and 51.32% respectively, and fluid accumulation was reduced by 39.45% and 57.87%. The study also revealed progressive diminution of Na+ and K+ concentrations in stool. There were significant reductions, (P<0.05) in frequency of wet stool, with lower curatives values of 10.00% and 24.00% than preventive values of 20.79% and 44.99%. The presence of some of the phytochemicals in the extracts may be responsible for the observed activities and attest to its utility in a wide range of diarrhoeal states. Further research to be carried on monitored fractionation and subsequent structural elucidation with a view to understanding the compound and possible mechanism of action.

  • Abstract

    Keratin genes are subgroup of intermediate filament (IF) genes. Keratins expressed in hair are called “hair keratins”. Comparison of keratin gene sequences and structural organization has been done earlier but no study has been undertaken that compares human hair keratin genes with orthologues in chimp, orangutan, macaque and platypus, with specific references to simple sequence repeats (SSRs) or microsatellites. This study seeks presence of SSRs in human hair keratin genes and compares their positions in orthologue genes. Although the structural organization of keratin genes is largely conserved, as reported in other studies; some human keratin genes show differences in the number of exons and the lengths of exons/introns, when compared with the orthologues. The present study shows few SSRs in human hair keratin genes, where only one repeat is found in exon of Type I keratin gene KRT31, while additional repeats are present in introns. Some repeats are longer in the human genes whereas some indicate reduction in length compared with orthologues. Many repeats are present in regions that are known for intronic variations. This study revisits the comparisons of structural organization of human hair keratin genes and compares them with the orthologues. The SSRs found here could be useful for monitoring variations in human
    hair keratin genes that may happen due to hypermutable nature of SSRs.

  • Abstract

    Phosphorous is one of the most vital micronutrients required for the growth and development of plants. Phosphate solubilizing bacteria enhances P availability in soil through dissolving inorganic P pool. 17 phosphate solubilizing bacterial strains were isolated from the rhizosphere of Castor (Ricinus communis), fields of Nalgonda district, Telangana State, India, on NBRIP agar. PSB1, PSB9 & PSB16 showed highest solubilization 370, 408 and 415μg/ml and belongs to the genera Bacillus, Pseudomonas and Klebsiella. 9 efficient PSB strains were further screened for their phosphate solubilization under heavy metal stress. 6 different heavy metals (Cu, Co, Cd, Pb, Ni & Cr) each with 4 concentrations (50, 100, 200 & 400μg/ml) were used. PSB9 showed tolerance to all heavy metals and solubilized the TCP under highest concentration i,e 400μg/ml, except for Ni and Cr where it shows the growth. PSB11 and PSB13 are considered as most vulnerable to heavy metals as it do not show phosphate solubilization under metal stress. The presence of heavy metals above critical concentration not only harmfully affects the human health but also the environment. Hence the results obtained suggest that, the isolated PSB9, a Pseudomonas strain can be used as a source to supply phosphorous to the plants in heavy metal contaminated soil.

  • Abstract

    An experiment was conducted at the research field of the Department of Genetics and Plant Breeding of Hajee Mohammad Danesh Science and Technology University (HSTU), Dinajpur to evaluate the phenotypic correlations between some traits and yield components of nine fine rice cultivars and also to determine the most effective factors on its yield. The experiment was laid out in a randomized complete block design (RCBD) with three replications. The nine fine rice cultivars namely Salsira, Binni pakri, Bolder, Joitha kathari, Ukni modhu, Salna, Radhuni pagol, BRRI 49 and Katarivog were evaluated. Analysis of variability parameters elucidate that the phenotypic coefficient of variation was higher than genotypic coefficient of variation for most of the trait studied. The plant height, non-filled grain number/panicle and yield showed high heritability and spikelet length showed low heritability. Yield displayed positive significant correlation with of spikelet length and days to 50% flowering but showed non-significant correlation with other traits

  • Abstract

    This paper presents observation of Oriental hornets (Vespa orientalis) in Jodhpur (Rajasthan) around their nest apparently made primarily by pulp/mud that had several openings. Some hornets were hovering over these openings and the brood cells. Studies on V. orientalis report that this fanning could be for cooling of the nest. There were some larvae/pupae lying on ground beneath the nest. It could not be confirmed however, whether these larvae/pupae fell accidentally or were purposely thrown out of the nest. Hornet sting does cause severe pain, which is more than honeybee or wasp sting. Immediate use of “Astheline” (salbutamol) inhaler spray on sting affected area and subsequent relief indicates a possible use of this spray as a first aid. However, this needs further confirmation. This paper also suggests further studies on uses and phylogeny of hornets based on perusal of published reports. Perusal of published reports on morphology and molecular data phylogenetic analysis indicate that morphological differences in hornets are possibly due to differences in environmental niche. Comparative studies on hornets from India (particularly from Rajasthan) and other regions of the world may help in confirmation of these findings

  • Abstract

    Brachydeuterus auritus is a species of fish which presents a strong potential for exploitation in the Ivory Coast. The present study focuses on the scale of maturity and the differentiation of the hepatopancreas. This scale has in females six stages. During sexual maturity, we note the growth of fish. The differentiation of the hepatopancreas is also carried out during this maturity. The anatomical plan, the hepatopancreas consists of two lobes uneven. The component presents a coloration, granulations and a vascularization which vary according to the stages of development. The histological plan, in the female the hepatopancreas is a joint body consisting of the liver and pancreas. The hepatic parenchyma is a homogeneous fabric, formed of hepatocytes which are polygonal cells. In addition, it distinguishes in the parenchyma of the hematopoietic tissues and centers mélanomacrophages, distributed near the blood vessels and bile ducts. The mélanomacrophages centers are composed of cells accumulating pigments. Within the body, the Pancreas differentiates centripetally. It is composed of exocrine cells and islets of Langerhans. The physiology of the two entities to know the liver and the pancreas determines the physiology of the body. The hepatopancreas intervenes in the reproduction, the digestion and the defense. It appears as a body to control many of the functions and plays an important role in the physiology of fish both in the anabolism that in the catabolism

  • Abstract

    Marine organisms are the potential source for bio chemical molecules. A variety of bio- active chemicals available among seaweeds, which is an important group of organisms in marine environment. The seaweeds available in the Gulf Of Mannar Biosphere Reserve (GOMBR), India, also showed intra and inter annual variations in their chemical composition. A total number of six seaweeds have been collected from the GOMBR in different seasons. Total protein content and haemagglutinin assays were carried over. The results showed the total protein content in greater variations during different seasons, with the maximum content during the summer season and the minimum content during the post monsoon season. Likewise, in the different blood groups, the haemagglutinin activity of the seaweed extracts showed pronounced variations, registering the minimum activity during the post monsoon season and the maximum activity during the summer season. Thus, the haemagglutinin activity of the seaweeds varied greatly corresponding to the protein content in different seasons. It suggests that protein content of the seaweeds is one of the important determining factors for the haemagglutinin activity. Further, it is concluded that the summer season is the best season for collecting seaweeds from GOMBR, for the extraction of protein and haemagglutinin.

  • Abstract

    Ethno-medicinally, extracts of Sapindaceae species in Nigerian folk’s medicine have been utilized to address various health disorders for which free radicals have been implicated. The increasing quest for plant based novel compounds of medicinal relevance led to the comparative investigation of the antioxidant activities of extracts of five parts of Blighia unijugata. Samples were collected and authenticated (Department of Botany) at University of Ibadan, Ibadan, Nigeria and separated into leaf, stem bark, root, flower and fruit. Flower and fruit were extracted separately in methanol (labeled MBuFlMeOH and MBuFsMeOH respectively), the leaf, stem bark and root extracts were obtained sequentially first with 100% hexane (MBuLfHex, MBuStHex, and MBuRtHex), and then with equal mixture of ethyl acetate and methanol (MBuLf 1:1, MBuSt 1:1, and MBuRt 1:1). Antioxidant activity evaluations was done using DPPH assay. Their 50% inhibitory concentration (IC50) values were determined by regression analysis on Microsoft excel. % inhibitions of DPPH for the eight extracts were between 32.26% - 96.56% which is comparable to values obtained for the standards (Vitamin C, Anisole and Vitamin E) used (63.36% - 97.09%). IC50 values for DPPH scavenging activities of the eight extracts studied gave the following trend: MBuLf 1:1>MBuSt 1:1>MBuFs MeOH>MBuRt Hex>MBuRt 1:1>MBuFl MeOH>MBuSt Hex>MBuLf Hex, with their corresponding IC50 values being 0.0277 > 0.0284 > 0.0301 > 0.0317 > 0.0320 > 0.0342 > 0.0360 > 0.0400 (mg/ml) respectively. All the five parts studied are potential good sources of free-radical scavenging compounds; this supports the ethno-medicinal application of Blighia unijugata as anti-ageing agent

  • Abstract

    To evaluate and compare the intersurface gap in class V cavities restored with three different tooth-colored restorative materials using the scanning electron microscope. Thirty extracted premolars were randomly selected for this study. Standardized classV cavities were prepared and then divided into three equal groups. Group I was restored with nanofiller composite, Group II was restored with hybrid composite and group III with polyacid modified composite. They were then subjected to thermocycling, sectioned and examined under scanning electron microscope. An intersurface gap for each section was recorded and data was analyzed. Lowest intersurface gap was recorded in group I and highest leakage recorded in Group III. Nanofiller composite resins provide a better sealing than the hybrid and polyacid modified composites

  • Abstract

    Exposure to cadmium (Cd) an inorganic toxicant cause serious health and environmental problems as a result of pollution from a variety of sources. The present study aimed to assess the possible attenuation role of propolis on Cd toxicity in rats using hematological, biochemical and histopathological approach. Twenty four adult male rats were divided into four groups (the first group was kept as control (G1), second group (G2) received proplis by gavage (300 mg/kg body weight (b.w)), third group (G3) received Cd by gavage (5 mg/kg b.w) in form of cadmium chloride (CdCl2) and fourth group (G4) received propolis +Cd) for 4 weeks. Hematological parameters revealed that Cd ingestion resulted in significant decrease of RBCs count, hemoglobin concentration (Hb) and mean corpuscular volume (MCV), leukocytosis and increase platelets count. While, biochemical study revealed significant reduction in serum albumin and total protein (TP), plasma reduced glutathione (GSH), superoxide dismutase (SOD) and glutathione reductase (GR) whereas serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), creatinine, urea, uric acid, triglycerides, total cholesterol, glucose and plasma lipid peroxidation product (malondialdehyde, MDA) and hydrogen peroxide (H2O2) were significantly increased. Moreover, histopathological examination of Cd treated rats revealed marked alterations in liver, kidneys, brain, and testes. Fortunately, synergistic administration of propolis and Cd resulted in significant amelioration of negative effect of Cd on the investigated hematological and biochemical parameters. Moreover, propolis administration was able to protect tested organs against Cd toxicity. It was concluded that propolis exhibit remarkable protective effect against cadmium toxicity.

  • Abstract

    The methodological approach has been to a macroscopic description of the hepatopancreas in function of the six stages of sexual maturity. The histological study has need the mounting, dehydration, the impregnation, inclusion, the achievement of the planes of the hepatopancreas and their coloration in view of their observation. At the macroscopic plan, the size and the color of the hepatopancreas vary, by contrast, its appearance and shape remains unchanged during the growth of the fish. It is composed of two lobes, the liver lobe left always more developed than the hepatic lobe right. The microscopic study of the hepatopancreas of the male has revealed that it is constituted of hepatic parenchyma and pancreas. The hepatic parenchyma is composed essentially of hepatocytes and blood vessels. The hepatocytes of polygonal shape, are prepared in cords around the capillaries sinusoids. The Pancreas consisting of the islets of Langerhans (endocrine pancreas) and serous acini (pancreatic exocrine pancreas) gradually invaded the hepatic parenchyma toform the hepatopancreas. The hepatopancreas is an essential organ in the physiology of the fish. It intervenes in the nutrition, reproduction and the general metabolism.

  • Abstract

    The aqueous extracts of different concentration of walnut’s husk were investigated for their phytochemical & antibacterial properties. The husk extracts were made using the simple infusion, decoction infusion and microwave infusion. The different concentration of extracted extracts showed antibacterial and antifungal activity, which were shown in the results of our study. Phytochemical analyses revealed the presence of Alkaloid, Phenols, Flavanoids, Protiens and Amino acid, Saponins, Quinones, Terpenoids. Antibacterial potentials were evaluated using the agar disk diffusion method. The extracts were inactive against all the gram negative bacteria which were used in current study but on other hand it inhibits the gram positive bacteria effectively on different concentration. The walnut, leaves , bark and its stem’s extracts have unique quality to inhibit the fungal and bacterial growth but on the other hand we observed that walnut husk has different property as compare to its inner seed, husk extract were enhancing the growth of some fungal strains which we tested during our study.

  • Abstract

    Pectic substances are complex high molecular mass glycosidic macromolecules found in higher plants. They are present in the primary cell wall and are the major components of the middle lamellae, a thin extracellular adhesive layer formed between the walls of adjacent young cells. Agro-industrial residues are primarily composed of complex polysaccharides that strengthen microbial growth for the production of industrially important enzymes. Pectinases are one of the most widely disseminated enzymes in bacteria, fungi and plants. In the present study, the production of pectinase using Aspergillus niger NCIM 616 was carried out under solid-state fermentation using mixed substrate. Sapota (Manilkara zapota) seed powder and pumpkin (cucurbita) seed powder, were selected and mixed in different ratios for fermentation medium. The maximum production was obtained at the ratio of 2.5:2.5(Sapota seed powder: Pumpkin seed powder). Different parameters optimization processes were investigated on SSF namely fermentation time (5thday), temperature (350C), pH (5.0), and moisture content (80%), inoculum volume (2ml), inoculum age (5thday) and nutrient supplements possessing sucrose as carbon source and Sodium nitrate as nitrogen source. The produced enzyme was partially purified by ammonium sulphate salt precipitation and dialyzed, and showed maximum activity (280.82U/ml).After the partial purification the enzyme was immobilized and showed maximum pectinase activity (260.15U/ml). This activity is less the than free enzyme activity because the immobilization process blocks some active sites of the enzyme. Reuse of immobilized beads showed stable activity upto 14thcycle and later decrease of the enzyme activity is observed. This may be due to leakage of enzyme

  • Abstract

    Copper is one of the most important micronutrients of plant but enhanced accumulation of it can cause toxic effects on plant. Dihydroflavonol-4-reductase plays pivotal role in anthocyanin production via phenylpropanoid and anthocyanin biosynthesis pathway. This present study is focused on elucidating the importance of Dihydroflavonol-4-reductase in production of anthocyanin and also its role in withstanding copper induced toxicity in Plantago ovata. Hence, this study describes how copper stress induces higher expression of DFR and thereby increases the anthocyanin production to withstand stress. Partial cds of DFR gene was isolated, sequenced and its expression pattern was studied under copper stress. Anthocyanin content was measured to get an idea about the effect of copper toxicity on its accumulation. Copper in plant cells is kept at lower concentrations because at higher concentrations it acts as a cytotoxic stress factor. Correlation between induction of DFR expression and anthocyanin synthesis to protect plant against copper induced oxidative stress was observed. This study would enable to understand the genetic regulation of DFR induction due to copper toxicity. The up regulation of its expression under copper stress confirms its important role in anthocyanin production. This study also depicts the protective role of anthocyanin in plants against copper stress.

  • Abstract

    The species of Adansonia digitata L. (Bombacaceae) is an endangered medicinally important forest tree. It is known as Kalpavriksha as all the parts of the tree such as leaves, seeds, flowers, fruit pulp, bark and roots are used in the preparation of food products, medicines, fuel, timber and fodder. The leaves and fruit pulp of A. digitata are known to be rich in many mineral nutrients such as calcium, iron, vitamin A and C. The aim of the present investigation was to estimate the amount of vitamin C in leaves and fruit pulp of A. digitata and also to compare their percentage with fruits of orange and lemon. The results revealed that the fruit pulp was found to possess more amount of vitamin C than in leaves of A. digitata and Orange but less than the Lemon fruit.

  • Abstract

    The aim of this study was to characterize the bioactive constituents and to evaluate the antioxidant activity of five pepper (Capsicum annuum L.) cultivars. Phenols, flavonoids, flavonols and ascorbic acid were quantified in the pericarp of the peppers studied. The antioxidant activity of their extracts was evaluated by the method of radical scavenging of DPPH•. The solvents used for the extraction of these metabolites are water, methanol and ethanol at 75%. Preliminary results have shown that the composition of the peppers in bioactive elements varies depending on the type pepper and the solvent extract. The hot and sweet red pepper showed high vitamin C content (respectively 34.49 and 33.4 mg / 100 g FW) followed by hot green pepper, sweet green pepper and yellow pepper. It was also found that capsaicin vary significantly (P<0.005) among peppers studied. Capsaicin contents ranged from 6, 78 to 32, 50 mg/100 FW. The maximum capsaicin content was noticed in hot green and hot red peppers. The highest contents of phenolic compounds, flavonols and flavonoids were in sweet and hot red peppers. The highest radical scavenging activity (IC50) was observed in red and yellow peppers for ethanolic and methanolic extracts.

  • Abstract

    The present work deals with the synthesis of copper nanoparticles from fresh leaves of Phyllanthus amarus using different concentrations of copper chloride such as 1, 3 and 5 mM. The nanoparticles formed were characterized by UV–Vis absorption spectroscopy and SEM analysis. The size of the nanoparticle was 74–540 nm. Leaf and stem extracts of P. amarus were prepared using acetone, ethanol and water. The antibacterial activity of P. amarus leaves and stem on E.coli, P.mirabilis, B. cereus were evaluated by agar well diffusion method. The maximum zone of inhibition of 20 mm was observed in the acetone extracts of leaf and stem against P. mirabilis, B. cereus in acetone extracts of leaf and stem were observed. The ethanol and aqueous extract showed a zone of 17 mm and 14 mm for the same. The synthesized copper nanoparticles were active against all the three microorganisms tested and the zone of inhibition ranged from 6 mm to 23mm. The acetone and ethanol extract of leaf, stem, leaf & stem showed 100% lethality against Artemia larvae whereas the copper nanoparticles expressed 90% lethality at a concentration of 20 μg/ml.

  • Abstract

    The cost of Parkinson’s disease is substantial, including reduced quality of life, lost productivity, and increased health care expenditures. The lung diseases are the trigger cause of Parkinson and other neurodegenerative diseases; many cohort studies approved the relation worldwide, but southern cities have special identity of sandy weather at most of our time, rather than a type of work in cement factories. The increasing number of lung disease incidence was elevated at last 10 years ago rapidly, which increase the probability of relation, therefore, we stepped the time engine to approve the highly incidence of Parkinson disease and chronic ischemia. The experiment had conducted 10 patients with PD and measured the parameters in relation to hypoxia like hemoglobin content, iron, and uric acid, and compared the results with normal control using unpaired t-test. P-value ≤0.005 was considered to be statistically significant. The hemoglobin content in blood of Parkinson disease patients are expressed a significant inhibition with P≤ 0.05, compared to normal control (13 g/dl). While, the blood ferratin content of iron is considered the bridge line which connect the lung with the other parts of body. Hypoxia inducible factor -1 has ability to regulate a series of genes that control the iron homeostasis. The results of research have indicated significant sinking in iron level compared to normal control (100 ng/ml). It's clear declining in level of uric acid in Parkinson's patients comparing with normal control (6.3 mg/dl). It has been approved that lung disease increases the risk of Parkinson disorder via many metabolic and genetic pathways mainly the hypoxia; the situation that support using of iron tablet as drug of suggestion in mild cases rather than levodopa with its suppression side effect
