1 Sexual Activities and Initiation of Body Pain in Men , GhulamNabi,Muhammad Amin,Yousaf Khan,Sana Ullah,Jehan Zeb
Satisfied and normal sexual activity is a good indicator of quality of life. In the present study a link between the sexual activities and the initiation of mild back pain were studied. In married men after adopting various sexual intercourse positions, mild low back pain (6), knee joint pain (2) and neck pain (1) were reported. Similarly in masturbating group mild low back pain (4), temporary physical weakness (3) and general body aches (1) were reported. But, surprisingly in sex movies addicted group which were not engage in actual sexual intercourse, mild low back pain (4) and limbs pain (2) were reported the mechanism of which is still not understood.
2 Utilization of Biomass for Renewable Bio Energy Development, Abdeen Mustafa Omer
This communication discusses a comprehensive review of biomass energy sources, environment and sustainable development. This includes all the biomass energy technologies, energy efficiency systems, energy conservation scenarios, energy savings and other mitigation measures necessary to reduce emissions globally. The current literature is reviewed regarding the ecological, social, cultural and economic impacts of biomass technology. This study gives an overview of present and future use of biomass as an industrial feedstock for production of fuels, chemicals and other materials. However, to be truly competitive in an open market situation, higher value products are required. Results suggest that biomass technology must be encouraged, promoted, invested, implemented, and demonstrated, but especially in remote rural areas.
3 Effect of Biotic and Abiotic Stress on the Development and Production of Calligonum Polygonoides Subsp.Comosum Grown in Tunisian Arid Conditions , Adel Dhief,Lefi Elkadri, Samira Aschi-Smiti, Mohamed Neffati
In recent decades, pre-Saharian Tunisian consequences of desertification have gradually become a major environmental problem. We are witnessing the continuous degradation of natural vegetation, due to various human activities. These activities often lead to overgrazing, due to the decline in the size of the course (after cultivation) and increased grazing pressure, manifested by the degradation of the vegetation cover. Such quantitative and / or qualitative degradation is accompanied by irreversible changes in the flora and, therefore, plant faces marked by the dominance of abandoned animals by species. To study the effects of seasonal drought and grazing on the parameters of vegetative growth and floristic diversity in canopy, several cuts were made and transects were installed in an experimental plot located in the region of El Ouara (southern Tunisia). Recovery and floristic density were measured during two seasons (fall and spring) with the use of point quadrat method. The main results of this study show that: For physically undisturbed plants, high productions were recorded in spring and summer. However for physically disturbed plants, that is to say, cut twice, the species showed in irrigated and dry higher capacity spring regrowth (cut in February-March). In general, a significant difference of biomass (B) between the two regimes was observed in spring. Grain production was limited to spring in both water regimes. The annual / perennial ratio is more influenced by seasonal drought the effect of grazing in the sense of a reduction of vegetation cover is more remarkable in the fall. The overall recovery of the vegetation may be considered a good indicator of the structural state of the ecosystem. Alpha and beta diversity is in turn good indicators of ecosystem structure that should be followed in similar studies
4 Preliminary Phytochemical Evaluation and HPTLC Fingerprinting of Leaves of Azadirachta indica, Sunita Dalal, Leena Seasotiya, Sheema Bai, Pooja Bharti,Anupma Malik
The fingerprint profiles of methanol extract and ethyl acetate sub fraction of Azadirachta indica leaves were conducted using preliminary phytochemical screening and high performance thin layer chromatography (HPTLC) analysis. Preliminary phytochemical screening was performed using various biochemical tests. Alkaloid, flavonoid, tannin, saponin and phenol were present in both the extract/subfraction. Toluene:Ethyl Acetate:Formic acid::5:4:1 was the finalized solvent system for both the extract and sub fraction indicating it to be the best solvent system for determination of phytochemicals of the studied plant. HPTLC finger print of methanol extract showed 16 peaks and the Rf values ranged in between 0.03 to 0.96. Similarly, ethyl acetate sub fraction confirmed 18 peaks and the Rf values ranged in between 0.03 to 0.95. HPTLC fingerprint analysis of A. indica (leaf) can be used for the exact detection of the plant. Also it is useful as a phytochemical marker and a technique to check the genetic variability in various plant species.
5 Head-Leg Feathers in Fancy Pigeons of Bangladesh , M. Ashraful Kabir
Out of 8 types of head-feathers tumbler and fantail showed the highest 4(50%) whereas the second lowest were in lotan and australian red 2(25%). In case of leg-feathers highest percentage (100%) were found in tumbler and pouter and lowest 3(60%) in lotan, fantail and lahore respectively. Head and leg feather looks nice but it was hazardous during breeding and non-breeding time. Leg-feathers are more unnatural than head-feathers. Feather in legs carry huge germs, got wet during taking water, breeding problem, unsafe and walking difficulties. For avoiding such problems trimming of both feathers is must.
6 Carcass Composition and Product Quality of Clarias Gariepinus Fed 5% Dietary Levels of Leaf Meals, D.C. Anyanwu, J.I. Offor,B. Onogu,,M. Mbachu
The carcass composition and product quality of Clarias gariepinus fed dietary levels of 0% leaf meal, 5% levels of Ocimum gratissimum leaf meal (OGLM), Telfaria ocidentalis leaf meal (TOLM) and Azadirachta indica leaf meal (AILM) were investigated. Four 36% isonitrogenous diets of these leaf meal levels respectively, were formulated and fed to the post fingerlings, randomly assigned to the four treatments- control (Tzn), 5%OGLM (To), 5%TOLM (Tt) and 5%AILM (Ta) in three replicates of 15 post fingerlings each, using twelve plastic aquaria of 250 x 150cm dimension. The fish were fed at 5% body weight twice daily within the experimental period of 56 days. There were significant differences (P0.05) in the quality of fresh raw samples, whereas those of cooked fish samples were slightly different. The result of this study showed that 5% dietary levels of OGLM, TOLM and AILM could support optimal carcass composition of Clarias gariepinus without deleterious effect on the fish quality. `
7 Retinoids Hamper Inflammation in Normal and Cancer Epithelial Cell Lines , Alessio Papi, Marina Orlandi
Inflammation is considered one of major causes of cancer and hamper inflammation is possible target of chemotherapy and chemopreventive treatment. Retinoids have potential anti-inflammatory effects. We investigated the effects of the retinoid all-trans retinoic acid (RA) and the 6-OH-11-O-hydroxyphenantrene (IIF), a specific ligand of Retinoid XReceptor (RXR), on the normal keratinocyte cell line NCTC and on the neuroepithelioma cancer cell line SKNMC. IIF and RA treatment inhibited proliferation and viability in a time and dose dependent manner. Interestingly, IIF was significantly more effective than RA and reduced of 50% SKNMC cells after 24 h of treatment at the dose 30 M. The effects are further evident in cancer cells than normal cells where retinoids reduce slightly the viability. We stimulated inflammation with LPS and TNF? in normal and cancer cells and we observed the effects of IIF on several catechins involved in inflammation. A reduction of TNF?, IL2 expression and IL6 production after treatment with IIF in SKNMC cells was reported. Moreover, IIF reduced IL18, IL15 and IFN? expression in inflammatory NCTC cells. Finally, inflammation induction increased while IIF treatment reduced matrix metalloproteinase-2 and -9 activity, two proteins that are involved in cell invasion and metastasis. In conclusion, we suggest that retinoids as IIF could be used to overcome inflammation in human carcinoma and it may be a powerful tool in the development of cancer therapies
