Abstract: The medicinal properties attributed to resins of this plant in Sudanese traditional medicine prompted us to study the chemical composition of the oil. The GC/MS chromatogram of the oil revealed the presence of 58.86% monoterpenes and 23.28% sesquiterpenes. Predominant monoterpenoids were; m-cymene (21.56%), linalool (7.21%) and p-mentha-1-en-8-ol (5.28%) while the predominant sesquiterpenoids were; alpha-guaiene (3.55%) and C15H24 (3.23%).

Abstract: As shade adapted organisms the conchocelis of Pyropia contain high concentrations of photosynthetic pigments, making the conchocelis a potential source for the extraction of bioactive pigments such as phycoerythrin, phycocyanin and carotenoids. The pigment content of Pyropia conchocelis in response to environmental factors is poorly known. Investigations were performed on the production of carotenoid pigments as a function of environmental variables by the conchocelis phase of Alaskan Pyropia species: Pyropia abbottiae, P. hiberna,P. tortaandP. sp. Conchocelis fragments were cultured under different irradiance, and nutrient concentrations for up to 60 days. Results indicate that carotenoid pigments were significantly affected by irradiance, nutrient concentrations and culture age, with some interactions of these factors. Carotenoid pigment content varied in a similar manner for each species. Light had the most obvious influence on carotenoid content. For all four species, the highest carotenoid content (3.4-7.0mggdw-1) generally occurred at 0-10µmol photonsm-2s-1. Higher irradiances, low nutrients and longer culture age generally caused a decline of carotenoid pigment content. There were significant differences in carotenoid pigment content for different species. P. abbottiae and P. sp. produced higher pigment content than the other two species. Maximal carotenoid content for P. abbottiae was 7.0mggdw-1. P. torta contained the least carotenoid pigment under all culture conditions. Carotenoid pigments remained highest under continuous darkness for as long as 60 days for all tested species. The present study investigated the effects of environmental variables on the carotenoid content of Porphyra conchocelis and determined the optimal cultural conditions, which would helpful for obtaining algal material with higher pigment content and extraction of high value pigment.

Dysregulation of Phospholipid Metabolism in Synaptic Membranes and Their Role in Encephalopathy Forming After a Hemorrhagic Shock

Abstract: Phospholipids (PLs) of neuronal membranes are active universal neuromodulators. They regulate many functions of the neurons, including receptors signaling, which during a hemorrhagic shock (HS) get damaged, leading to encephalopathy. An analysis of the data, presented in this review, suggests that the dysregulation of PL metabolism in synaptic membranes is a key mechanism of encephalopathy during HS. Stabilizing the PL composition of the neuronal membranes may become one of the most important treatment methods for shock-induced disorders of brain functions.

Abstract: Many diseases and genetic disorders are associated with ABO and Rh systems of blood antigens. This study was conducted to determine the frequency of ABO and Rhesus (Rh) blood groups in District Rahim Yar Khan, Pakistan so that the results could be used for further application. A total of 9891 subjects including patients and healthy individual were sampled only belonging to District Rahim Yar Khan during this study. The ABO and Rh blood grouping were carried out by tile method using commercially available anti sera and subsequently the frequency of each blood type was computed. Out of 9891subjects 7451 were male, while 2440 were female. In both genders the prevalence frequency of ABO, association between ABO and Rhesus blood grouping systems was computed and analyzed. The brought out the conclusion that blood group B is at the highest frequency level among both the genders with an overall higher to lower order B (37.41%), O (33.95%), A (20.97%), and AB (7.65%). The blood group B was also at the highest frequency in Rh+ve as well as Rh-ve in male subjects. However, in female subjects the blood group O (33%) was at the highest frequency in Rh+ve and blood group A was at peak in Rh-ve .

Abstract: Low temperature or cold stress is one of the major abiotic stresses for bean seeds production. The objective of this study was to analyze the effect of cold stress on Phaseolusvulgaris l seeds by doing different types of tests(germination studies, respiration response, conductivity test, amylase and catalase test) at different temperatures like room temperature, at 3° C and at - 19° C. Seeds were germinated in germination box. Germination percentage, rate, seed vigour and germination index was measured. Respiration response was also analyzed. The procedure does not quantify a respiration rate, but it indicates that respiration rate can be compared across different treatments. Observation from conductivity measurement shows that leachate solution of -19° C gives low conductivity whereas 3° C gives moderate and at normal room temperature it was high. Low temperature showed high amylase as well as catalase activity. Room temperature showed a good response against few parameters but not in enzyme activity.
