Three biological cells osteoblasts, osteoclasts and osteocytes are important players in creating new bone or osseous matter in which quite a few hormones, proteins and minerals have indispensable supportive role. Assuming populations of the three mentioned cells as variables, we frame a theoretical model which is represented as a set of time differential equations. These equations imitate the dynamic process of bone matter creation. High value of osteocytes with moderate level values of osteoblast and osteoclast, all at asymptotic scale, imply creation of new bone-matter in our model. The model is studied both analytically and numerically. Some important results are highlighted and relevant predictions are made which could be put to future experimental test.","PeriodicalId":14548,"journal":{"name":"IOSR Journal of Pharmacy and Biological Sciences","volume":"154 1","pages":"07-20"},"PeriodicalIF":0.0,"publicationDate":"2019-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75296233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Haemoglobins A2, C, E and O Arab migrate together during cellulose acetate electrophoresis and are often not differentiated by most diagnostic laboratories. This study investigated the instability of phenotyped haemoglobin-C individuals and the possibility of haemoglobin-E individual phenotyped as either heterozygous or homozygous haemoglobin-C. Fifty phenotyped blood samples consisting of twenty five haemoglobin-AC, fifteen haemoglobin-SC, and ten haemoglobin-CC were used for this study. Twenty two blood samples phenotyped as haemoglobin-AA served as controls. The blood samples were analyzed for haemoglobin instability using heat instability and isopropanol instability tests. The difference in turbidity of the haemoglobins measured spectrophotometrically before and after heating was taken as a measure of haemoglobin instability. The degree of instability in haemoglobin-AC individuals was insignificant (p>0.05) in relation the controls. A significant (p<0.05) level of instability was found in haemoglobins-SC and CC individuals. Two haemoglobin-AC and one haemoglobin-CC individuals showed very high concentration of haemoglobin instability. They recorded turbid reaction with isopropanol. This suggests Haemoglobin-SE, Haemoglobin-CE or Haemoglobin-EE erroneously phenotyped as haemoglobin-SC and haemoglobin-CC. This study concludes that Haemoglobin-E may be present in Nigeria.","PeriodicalId":14548,"journal":{"name":"IOSR Journal of Pharmacy and Biological Sciences","volume":"39 1","pages":"59-62"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75431835","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A pole clipper system was used, and in vitro viability measures, to evaluate relative impact of such factors in six forest tree species. Relative pollen viability was measured with Alexander’s stain, or TTC stain for Madhuca indica Gmelin. (Sapotaceae); Buchanania lanzan Spreng. (Anacardiaceae); Pterocarpus marsupium Roxb. (Fabaceae); Alangium lamarckii Thw. (Alangiaceae); Schleichera oleosa (Lour.) Oken (Sapindaceae) and Tectona grandis Linn. (Verbenaceae). The impact of thrips was gauged from bagged and open flowers, and direct counts on flowers in Buchanania and Tectona; canopy position impact (affecting light, exposure, temperature) was gauged using collections made with pole clippers, and by reciprocal transfer of inflorescences on branches. Four native bee species were scored for viable pollen as they first left their nests in early morning. Viability decreased according to thrips presence in Buchanania and Tectona. The former had more thrips and significant damage only among lower flowers, while the latter showed most thrips damage on higher flowers. Pollen viability was higher on the higher flowers in Tectona, Madhuca, Buchanania, Pterocarpus, Alangium and Schleichera. Pollen viability in transplanted inflorescences changed in Tectona, Madhuca, Buchanania, Pterocarpus, Alangium and Schleichera. Viable pollen was recovered on native bees first leaving their nests in early morning, indicating prolonged pre-pollination potential. Various factors influence pollen viability in tropical field conditions. Thrips may effectively remove a large portion of pollen and exert more influence than physical exposure. Some flowers increase in pollen viability when exposed to gap conditions, but others show the opposite trend, with implications for degraded habitats. Bees may secondarily disperse viable pollen from their nests, in which it retains viability from one day to the next. Relative pollen viability was in agreement using different in vitro tests.","PeriodicalId":14548,"journal":{"name":"IOSR Journal of Pharmacy and Biological Sciences","volume":"10 1","pages":"20-25"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77265826","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(MEHF) in high fat cafeteria diet (HFCD) fed obese rats. Methods: Wistar strain of albino rats were divided into six groups comprising of six rats each. Group I served as normal control fed with normal pellet chow, group II served as disease control fed with high fat cafeteria diet, group III, IV and V animals, received MEHF at a dose level of 100, 200 and 400mg/kg b.w along with HFCD for 40 days, while, group VI served as standard drug control, which received Orlistat at a dosage of 50mg/kg b.w along with HFCD. Results: Administration of HFCD for 40 successive days to experimental rats significantly increased the body weight, organ and fat pad weights, serum total cholesterol, LDL cholesterol, VLDL cholesterol, triglycerides and glucose levels; and decreased HDL cholesterol as compared to normal control. While treatment with MEHF showed a significant reduction in the body weight gain, organ weight of the liver, kidney, spleen, weight of fat pads and the levels of serum triglycerides, total cholesterol, LDL cholesterol, VLDL cholesterol, glucose and increase in HDL cholesterol in a dose dependent manner. Further, the levels of liver markers such as aspartate transaminase (AST), alanine transaminase (ALT) and alkaline phosphatase (ALP), which were found to be elevated in the serum of obese rats, also resumed to normal on treatment with different concentrations of MEHF. Moreover, the consumption of MEHF reduced oxidative stress by enhancing the levels of glutathione (GSH), glutathione peroxidase (GPx), super oxide dismutase (SOD) and catalase in the hepatic tissue of rats with HFCD induced obesity. Conclusion: These results demonstrate clearly that repeated oral administration of Heritiera fomes methanolic extract can evoke a potent anti-obesity activity.","PeriodicalId":14548,"journal":{"name":"IOSR Journal of Pharmacy and Biological Sciences","volume":"36 1","pages":"01-05"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89682662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Light isotope ( 12 C) is favoured against the heavier isotope ( 13 C) during the carbon fractionation in plant species. The ẟ 13 C values of terrestrial plant are useful in diverse applications in ecological, forensic, microbial diagnostic, biochemical and other scientific studies. There is variation of the ẟ 13 C values between the intraspecies grown in the greenhouse under controlled climatic conditions except respired carbon dioxide concentration. Also, ẟ 13 C values variation exist between interspecies, both grown in the greenhouse and field conditions. Isotopic composition of respired carbon dioxide (carbonate, CO3 ) was different from that of plant carbon dioxide (carbonate, CO3 ) and may be accounted due to respired carbon dioxide refixation. Further differences in the respired carbon exist between the C3 and C4plant species. Diffusion of carbon dioxide, interconversion of carbon dioxide and bicarbonate, assimilation of carbon dioxide by Ribulose bisphosphate carboxylase or Phosphoenol pyruvate carboxylase during carbon fractionation affect the final ẟ 13 C values. Different climatic factors and carboxylating enzymes explain the variation in the ẟ 13 C values within and amongst the C3 and C4 plant species. Furthermore, the variation in ẟ 13 C values may be caused by genetic differences in either leakiness of the bundle sheath cells due to light-use efficiency or by differences in the ratio of assimilation rate of stomatal conductance due to transpiration efficiency. Thus, both kinetics and thermodynamic modelling can be applied to explain the carbon fractionation process and theẟ 13 C values.","PeriodicalId":14548,"journal":{"name":"IOSR Journal of Pharmacy and Biological Sciences","volume":"9 1","pages":"51-58"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87357497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
