Marine microbes use a variety of strategies to colonize both animate as well as inanimate surfaces in marine environment. The competition among microbes to colonize surfaces acts as a potent selective force. One of the important strategies these microbes use is the secretion of antimicrobial compounds, which helps to inhibit the growth of the competitors. Bacterium - bacterium antagonistic interactions involving antibiotics are well documented in soils but work relating to this in marine environment is scanty. In this present study 75 antibiotic producing bacterial strains were challenged to enhance the production of antibiotics by these strains. Enhancement of antibiotic production by the producer strain was carried out by inducing the producer strains with heat killed and live Escherichia coli and Pseudomonas aeruginosa cells. Out of the 75 induced strains 21 strains were found to enhance their antibiotic production. In the search for novel antibiotics from marine bacteria, these strategy can be used to enhance production of the potent compounds to overcome the problem of low yield to a certain degree.

The ethanolic leaf extracts of Solanum trilobatum plant were used for antibacterial study by disc diffusion method. Different concentrations (10mg/ml, 20mg/ml, 30mg/ml) of the concentrated ethanolic leaf extract were tested for its antibacterial activity against bacterial strains such Bacillusubstilis, Staphylococcus aureus, Bacillus cereus, E. Cali & Pseudomonas aeruginosa. The bacterial cultures were grown in Muller hinton agar and Muller hinton broth. The zone of inhibition was comparatively more in the concentration of 30mg/ml. Phytochemical screening of the ethanolic leaf extract of the plant revealed the presence of tannins, saponins, flavonoids, carbohydrates and alkaloids. Thin Layer Chromatography (TLC) value of the leaf extract showed the highest Retention Factor (RF) value. The plant extracts showed better inhibitory activity against the tested organisms.

This study focuses on the phytochemical properties and the anti-hepatocarcinogenic effects of the leaf and in vitro-derived callus and shoot extracts of Solanum trilobatum. In the leaf, callus and shoot, the presence of sugar, proteins, alkaloids, flavonoids, saponins, tananins, cardiacglycoside, terpenoid and lipids was established by preliminary phytochemical screening. Surface-sterilized explants (0.5-1.0 cm) were placed on the MS basal medium supplemented with different concentrations of 2,4-dichlorophenoxyacetic acid (0.45, 2.26, 4.52, 11.31 and 12.56μM), naphthylacetic acid (NAA; 0.54, 1.34, 2.69, 5.37, 13.43 and 26.85μM) and 6-benzylaminopurine (BA; 0.44, 1.11, 2.22, 4.44, 8.88 and 13.32μM) for callus induction. Explants from node and callus culture were inoculated on the MS basal medium supplemented with varying concentrations of BA (0.44-22.20 μM) and NAA (0.54-10.74μM) for shoot multiplication. Rats were divided into five groups and administered with diethyl nitrosamine (DEN) and DEN (200mg/kg bwt) intraperitoneally along with methanol leaf and in vitro-derived callus and shoot extracts (250mg/kg bwt) orally for 3 months. A significant deviation (P<0.05) in marker enzymes such as alanine transaminase, aspartate transaminase, lactate dehydrogenase and total bilirubin was found in rats administered with DEN. The liver tissue was used for the analysis of glutathione reductase, lipid peroxidation, glutathione peroxidase, glutathione S-transferase, superoxide dismutase and catalase. DEN administration caused a significant elevation in serum enzymes and total bilirubin. Moreover, antioxidant enzymes were drastically inhibited with significant reduction in glutathione and increased lipid per oxidation. Increased glutathione level and reduced lipid peroxidation were also evident in S. trilobatum-treated rats. However, crude S. trilobatum and in vitro-derived callus and shoot extracts offered better protection against free radical toxicity induced by DEN.

It is estimated that globally there is a marked increase in liver disease with reports of rising morbidity and mortality, particularly in younger age groups. Brainstem auditory evoked potential (BAEP) was recorded in 60 decompensated chronic liver disease (DCLD) subjects who fulfilled the selection criteria and compared to 60 age and gender matched healthy subjects with normal liver functions. DCLD subjects were divided into two inter groups based on presence or absence of hepatic encephalopathy (HE). Group 1 comprises of 30 subjects of grade- I HE and Group 2 included 30 subjects without hepatic encephalopathy (NHE). Absolute and interpeak wave latencies were measured. Results were analysed by student independent t- test using SPSS software 11 version. Statistical significance was tested using P value. From the present study it can be concluded that the central nervous system is involved in liver cirrhosis evidenced by an abnormal BAEP latencies parameters. This shows that there may be progressive demyelination occurring along with axonal loss or dysfunction in liver cirrhosis HE. This study suggests that periodic evaluation of cirrhotic individuals to such test will help in monitoring the progress of encephalopathy. The prime goal of this study is early diagnosis and initiation of treatment before the onset of coma can reduce the fatality rate.

Nowadays, renewable energies have been widely applied to achieve eco friendly objectives. This paper presents the development of a single-phase grid-connected wind energy generation with the improvement in power quality and efficiency. This mainly focuses on showing the improvement in power quality by overcoming the drawbacks with the existing wind energy generation based on the PLL with the discrete PI controller. It is found that Total Harmonic Distortions (THD) present in PLL Single-phase grid-connected wind energy generation can be reduced by using modified PLL method. The modified wind energy generation is based on PLL with Fuzzy logic controller instead of PLL with discrete PI controller. The PLL gets input from the load side, and compare with any one parameters current or voltage (closed loop system). The aim of this survey is to propose a new topology in (HCM) HILL CLIMB METHOD. The tasks related to the SVPWM algorithm, the PLL, the MPPT algorithm, and the monitoring of the DC voltage were successfully implemented in the DSC. © (2014) Trans Tech Publications, Switzerland.
