Phytoestrogens have multiple actions within target cells, including the epigenome, which could be beneficial to the development and progression of breast cancer. In this brief review the action of phytoestrogens on oestrogen receptors, cell signalling pathways, regulation of the cell cycle, apoptosis, steroid synthesis and epigenetic events in relation to breast cancer are discussed. Phytoestrogens can bind weakly to oestrogen receptors(ERs) and some have a preferential affinity for ERβ which can inhibit the transcriptional growthpromoting activity of ERα. However only saturating doses of phytoestrogens, stimulating both ERα and β, exert growth inhibitory effects. such effects on growth may be through phytoestrogens inhibiting cell signalling pathways. Phytoestrogens have also been shown to inhibit cyclin D1 expression but increase the expression of cyclin-dependent kinase inhibitors(p21 and p27) and the tumour suppressor gene p53. Again these effects are only observed at high(> 10) μmol/L doses of phytoestrogens. Finally the effects of phytoestrogens on breast cancer may be mediated by their ability toinhibit local oestrogen synthesis and induce epigenetic changes. There are, though, difficulties in reconciling epidemiological and experimental data due to the fact experimental doses, both in vivo and in vitro, far exceed the circulating concentrations of "free" unbound phytoestrogens measured in women on a high phytoestrogen diet or those taking phytoestrogen supplements.

salim Ali＇s fruit bat （Latidens salimalii） is Endemic to southern Western Ghats. India and is classified as Endangered by IUCN. Latidens is morphologically adapted to play a major role in the propagation of economically important trees： some of them are endemic to southern Western Ghats. This paper describes and documents, the bat＂s ecology, foraging behavior and food selection. The study is based on the dietary details of the discovered populations of L. salimalii in the Agasthiyar hill range and the High Wavy Mountains of southern Western Ghats, India. seeds. partially eaten fruits and seedlings germinated on the floor of the feeding roosts confirm this bat forage for fruits among relatively tall trees of evergreen forests in an elevation above 900 meter. Mist netting below and above canopy near the fruiting and flowering trees of their foraging area confirmed their interaction with certain endemic tree species. Their species specific dietars＇ preferences immensely help to restore and bring back the natural forest community structures.

A feasibility assay is conducted for electromyography measure in sternocleidomastoid and platysma, tenting to use it on Brain-Computer Interface (BCI) feedback. It is proposed a case of study for four healthy subjects with an average of 35 years old, two females and two males. Methodology proposed includes signal acquisition and processing with feature extraction of RMs, Mean and Variance. The data are acquired with the AD board NI UsB-6009, interfaced with LabView and processed in MatLab. An uncertainty analysis was made obtaining a system uncertainty of ±2.31 mV. ANOVA analysis was done, with a Randomized Complete Block Design (RCBD) experiment and interaction of factors and residues obtained with the software Minitab.
