In recent years, green synthesis of silver nanoparticles (AgNPs) has gained much interest from chemists and researchers and also increasing commercial demand for nanoparticles due to their wide applicability in various areas such as electronics, catalysis, chemistry, energy, and medicine. The present investigation attempted on bio-synthesis of sliver nano particles. These nano particles were biologically synthesis by using mangrove plant A. marina leaf extract.

Firefighters are susceptible to depression because at work they constantly face situations involving human suffering. Objective: To study occupational stressors and the occurrence of symptoms suggestive of depression. Materials and Methods: Cross sectional study with 181 firefighters of Mato Grosso do Sul – Brazil. The instruments were used: Work Stress Scale, Beck Depression Inventory and a Social Demographic Questionnaire. Results: 52.5% of the firefighters were classified in the high and moderate levels of occupational stress.

The phosphate solubilizing bacteria were isolated from the rhizosphere soils of Cotton, Brinjal, Bhendi, Tomato and Cluster bean. Two PSB isolates from each crop plants totally 10 PSB strains were isolated for further studies. The isolated PSB were identified by their morphological and biochemical properties. The isolated PSB strains were characterized under in-vitro by measuring the P solubilization zone in solid medium, phosphate solubilizing index, determining pH change of the medium and estimating the organic acid production, phosphates activity and available phosphorus.

The Asian Development Bank (ADB) Present study made to assess the response of Cowpea (Vigna unguiculata (L.) Walp) under the influence of copper with special reference to seed germination and seedling growth. Copper was applied in the form of copper-chloride (CdCl2 5H2O). Various concentrations of copper (0, 5, 10, 25, 50, 100, 150 and 200 mgl-1) were prepared and treated with various Cowpea varieties viz., CO 2, CO 6, CO 7, Paiyur-1 and VBN-2 were used for germination studies.

Marma is vital point where injury occur can lead to disability, dysfunctioning or even termination of life. It is not much developed in modern science. Acharya sushruta and vagbhata have explained it in detail in Sharirasthana of their respective samhitas. Almost all the samhitas of ayurveda have mentioned the total number of marma as 107. Marma’ s are the conglomeration of Mamsa, Sira, Snayu, Asthi and Sandhi. Little injuries to these marma points or anatomical areas can be fetal comparing with major injuries at anywhere else in the body.

The genotype of an organism expresses itself through the phenotype that is through proteins. Protein molecular markers provide indirect information about plant genome structure. Quantitative estimation of protein content from germinating seedlings was performed by Lowry assay. Total soluble protein analysis of all the species of Ipomoea under study was carried out by Native PAGE and SDS-PAGE, followed by isozyme analysis for Esterases (EST), Peroxidases (POX), Malate dehydrogenase (MDH), Ribulose bis-phosphate carboxylase-oxygenase (RUBISCO).

Periodontitis is classified as an inflammatory disease of the tissues of dental support caused by the deregulated production of inflammatory mediators against bacterial plaque, capable of destroying the periodontal ligament and alveolar bone, and can be of three types: chronic, aggressive and with manifestation of systemic diseases. The inflammatory process is the body's first defense response to disease facilities. However, exacerbation of the condition with excessive demand for inflammatory mediators may lead to the destruction of host tissue and produce irreversible pathologies.

Clinical specimens were collected from 120 patients, 44 of them are males and 76 females with age range 1-70 years. A total of 49(40.8%) isolates were diagnosed as P. aeruginosa based on a number of tests and confirming by using 16SrDNA gene specific for P. aeruginosa. Results showed that the highest antibiotic resistance was in 40(81.6%) isolates resistant to Amikacin (AK), while 26(53.1%) isolates were sensitive to Colistin (CT). All isolates were resistant to more than three antibiotics, therefore classified P.

The present investigation was carried out to study the effect of different growth regulators on propagation of Ravenia Spp. in subtropical zone under naturally ventilated polyhouse equipped with foggers at Mandouri farm of Bidhan Chandra Krishi Viswavidyalaya, Mohanpur, Nadia,West Bengal. Significant differences among the treatments (IAA @1000ppm, IAA@2000ppm, IAA @3000ppm, IBA @1000ppm, IBA @2000ppm, IBA @3000ppm, NAA @1000ppm, NAA @2000ppm, NAA @3000ppm and Control) on root emergence and proliferation were noticed.

The national halieutic production reached in 2014 a quantity of 1353 780 tons. The industry of transformation and valuation of the products of the peach in Morocco occupies an important place in the national economy because it’s treats about 70 % of the captures of the coast fishing and exports approximately 85 % of its production on hundred countries in the five continents. Now the pelagic fish industry generates a significant amount of waste up to 60%, are generally filed anarchically in the nature in the garbage dump and caused a negative impact on the environment and public health.
