Romance or Sex on a first date: Yes or No? 

Sex on the first date? Oh, here is a nice taboo topic that I know everyone talks about, with their friends and a few choice people. But few people talk about it out in the open. So the big question is really, yes or no, do we have sex on the first date or not? Well to tell you the truth, it's all a personal opinion. What if the sexual attraction is there between you and the other person? We know that sometimes when we meet someone for the first time, we get this feeling of wanting sex or romance. There is nothing wrong with it; we need to remember, it is still a feeling and apart of our everyday lives.
 




There is a vast ocean of knowledge connected with seduction pheromones. What is included here can be considered a fraction of this knowledge!


There are various ways to select the right perfume for yourself. Knowing how your tastes and styles are will often decipher which perfumes are the right match for you.

A great place to test out a new fragrance is often on either on the wrists or in the inside part of your elbow. These areas of the body are the best locations to test out perfumes. Waiting for about an hour or so will give time for the fragrance to settle onto the skin, as well as gives your body the chance to react to the scent. Pheromones in women react differently to scents. Therefore, what can smell great on one woman may not be the right scent for another.

Some examples of how to match the right scent for your personality: If you are adventurous and like to travel to distant lands, then perhaps a great scent to try would be something that has a very "crisp" scent. Women that may be more sensual will want something light and clean, perhaps like a baby powder soft fragrance.

ABSTRACT Bacterial biofilms are sessile communities with high cell density that are ubiquitous in natural, medical, and engineering environments; they are fascinating since they are primitive tissues with an advanced chemical communications network. Currently, there is an explosive amount of biofilm research, most of it with the ultimate aims of biofilm prevention, control, or eradication.The present investigation was aimed to study the cell signaling principle among seaweed epibiotic bacterial organisms , totally 54 bacterial isolates were made out of 20 seaweed species. Among 54 bacterial isolates 17 of them producer, another 17 of them inducer strains rest of 20 isolates were normal that have not showing any signs of activity. The 17 producers and 17 inducer strains were subjected to the cross species induction by quorum sensing principle and found that only 3 of them have responded to the cross species induction in production of antibacterial compound against the respective inducer strains. All the 3 producers and inducer were identified by biochemical analysis and surprisingly that all the 3 producer strain belongs to Genus Pseudomonas and inducer strains were belongs to Genus Vibrio. The supernatant obtain from mixed culture of Pseudomonas & Vibrio shows the antibiotic activity against the various Vibrio species which were isolated from other sources. Such as Vibrio from primary film, Vibrio from sediment Vibrio from seaweeds epibiotics. The obtain results clearly shows the particular Pseudomonas from seaweed epibionts has the capability of producing potential antibiotic compound against wide range of Vibrio species through quorum sensing.

In concluding this discussion, the quorum sensing is wider spread among bacterial population then was previously thought, (In Gram positive, Gram negative bacterial communication). Current assays for antimicrobial activities are inadequate because some antibiotic producing bacteria may require the presence of another bacterial species. These findings have important implication for the discovery of novel antimicrobial compounds from marine bacteria and may allow the development of new methods for screening novel compounds active against multidrug resistant bacteria.

Speaking from experience, I never did have sex on the first date or even the third date. Sometimes I am happy with it, and the other times I wish I did. Some people view sex like it is love making, not entirely true, well really it all depends on who you talk to. Some people will say that the sexual pleasure you give and receive should be from somebody special. The sexual attraction that is felt for someone is a thing that can not be held back but the actions can be. I guess the question should read, "Do we act on or feelings of sexual desires on someone we just met when the sexual attraction is there?"

Quorum sensing usually focused on the bacteria growing in homogeneous environment. However few studies have attempted to a study this principle in heterogeneous environment also. In this present investigation we have attempted to study both homogeneous as well as heterogeneous environment. In former one we have isolated producer strain in seaweed eipbionts and it shows inhibitory activity against the inducer organism at the same seaweed epibionts. Later producer strains from seaweed epibionts, were treated with various Vibrio organisms from different environment. The obtain result of this study shows that the producer strain are capable of secreting antibiotic compounds not only to their natural competitors in its own habitate but also to the pathogen inhabiting in a distant related environment.

BACTERIAL IDENTIFICATION The organisms responded to the quorum sensing process alone were identified by the following biochemical analysis.

In the present investigation, it was aimed to produce the antibiotics from the seaweed epibionts through quorum sensing principle. The bacterial isolates of seaweed epibionts were identified as species of Pseudomonas and Vibrio from seaweeds Hypnea musiformis and Gracillaria edulis. In this study the Pseudomonas acts as a producer strain and Vibrio as inducer strain. The recent finding says that the seaweed epibionts having potential to control the metabolic activity of competitor organisms. Allison et al., 1998 reported that many bacterial strains up on attaching to a surface produce exopolysaccharides or exopolypeptides. In addition, it has been postulated that exopolysaccharides could mediate the attachment of the bacteria to the surface and induce metabolic changes.

The earlier genetic analysis in Pseudomonas reveals the Pseudomonas consist of two quorum sensing systems as Las R1-I and Rh1R-l and have linked with R and I genes, in addition recently a third Lux R homolog that is advanced to a cluster of quorum sensing - controlled (qsc) genes were detected. Las R is a transcriptional regulator that responses primarily to the Las I - generated signal and Rh1R is a transcriptional regularly that responses best to the Rhl -generated signal. In Pseudomonas auriginosa, at low population densities Las I produce a basel level of 3-O-C12-HSL. As density increases, 3-0-C12-HSL builds to a critical concentration, at which point interacts with LasR. This Las R -3-0-012-HSL complex that activates transcription of a number of genes [Whileley, et al., 1999].

Most people, whatever your sexual preference, become aware of our sexuality, our innermost sexual desires, during adolescence. It's just a question of you are more sexually attracted to- the pin up hunk you drooled over on TV or the heroine of your favourite book or movie. Who do you dream about? Some girls have the usual lesbian experience during these teen years and this can tend to be the make or break for every budding lesbian. Lets face it if its women that get you going you are probably a lesbian.

The collected seaweed samples were thoroughly washed with sterile seawater to removes the loosely attached bacteria/particles. Seaweed fronds were scrubbed with sterile cotton swabs to obtain epiphytic bacteria. Epiphytic bacterial organism in the swab were inoculated in sterile peptone broth (50% sea water) and incubated at 28??C in an incubated shaker (220 rpm / min) for overnight. After the incubation period the enriched cultures were serially diluted up to 10-8 concentration and 200 microlitre of each diluted samples were transferred into the nutrient agar plate (50% sea water). The plates were incubated at 28??C for 5 days and the plates with crowded colonies were selected. In the crowded plates those colonies, which showed the sign of inhibition zone around its margin to the neighboring colony, were selected and considered as producer strain. The neighboring sensitive colonies were treated as inducer strain. Both producer and inducer strains were streaked repeatedly until to get pure culture. The pure culture were properly labeled and subjected to the quorum sensing analysis.

b) Among these 17-inducer strain 6 strains were isolated from Hypnea musiformis, 6 from Gracillaria edulis, 4 from Ulva lactuca & 1 from sediment.

Expressing yourself as a lesbian You can come across lesbians in every races, classes, cultures and professions - they are everywhere, whether you believe it or not. Many women find different ways of expressing themselves as lesbians , be it in the usual stereotypical way of shaving your head and wearing dungarees or, my preference, simply being in touch with your inner sexual being.

Perfumes and special scents are often the first things that will be noticed when people walk into the room, so it's best to make sure you are wearing the perfume that best reflects the kind of attention your wanting, e.g. a light scent for an interview or a more powerful one on a romantic date.

Love is such an emotion that is always pure, whether it exists between two heterosexual individuals or two women is inconsequential! Just take your time and express yourself and sexuality however you feel comfortable, you shouldn't have to force yourself to be a certain way, live you r life as you want to.

What ever your choice is, it is the right choice for you. Sexual attraction happens if we want it to or not. Everybody has their own opinion in this topic, just as I do and you do. If you decide to wait for that right person to come along and share nights of sex and romance with, so be it! If you are one for sex on the first date, the only advice I can offer is be careful, have fun and may your experience be as every bit of exciting as you hope!

ANTIBIOTIC ASSAYS Antibiotic activity was performed in duplicate using a standard paper disc diffusion method as well as well assay. In well assay 10mm in diameter wells were made in marine agar plates and the plates were swabbed with 16 hours old inducer strain. To these wells 200ul of cell free supernatant were added to each well. In paper disc assay the Watmann no.1 filter paper discs (6mm in diameter) were saturated with 200ul of cell free supernatant. The impregnant discs were Dlaced in the centre of the plates swabbed with test organisms. The plates were Incubated at 37??C overnight and observed for inhibition zone. The zone of inhibition was measured as the distance from the border of paper disc to the edge of the clear zone and expressed in mm.

Seaweeds itself secretes secondary metabolites to prevent fouling and grazing. In addition to that epibiotic bacteria on macro algae can also produce antifouling compounds that work in concert with the seaweed derived compounds to protect the seaweed surface. Recent studies have highlighted important roles of epibiotic bacteria colonizing the surface of seaweeds and releasing antifouling compounds. For the past 50 years antibiotics have revolutionized medicine by providing cures for formerly life threatening diseases. However, strains of bacteria have recently emerged that are virtually unresponsive to antibiotics such multidrug resistance, arising mainly through antibiotic misuse, is now recognized as a global health problem. In this situation, it is clear that new classes of antibiotics are urgently needed. Many marine bacteria have been shown to produce secondary metabolites that display antibacterial properties. The first antibiotic from a marine bacterium was identified and characterized in 1966. In addition, bacteria in biofilm on the surface of marine organisms have been documented to contain a higher proportion of antibiotic producing bacteria than some other marine environments (Burgess, et al., 1999). Marine epibiotic bacteria, associated with nutrient-rich algal surfaces have also been shown to produce antibacterial secondary metabolites which inhibit the settlement of potential competitors. Recently a lot new novel antibiotics such as Phenazine, thiomarinol, phenazine-1-carboxylic acid, 1-hydroxyphenazine 2-n-heptylquinol-4-one, 2-n-nonylquinol-4-one pyolipic, loloatins, agrochelin, sesbanimides, pelagiomicins, indomycione and indomycione have been identified from various marine epibiotic bacterial organisms. In particular, some species of the genus Pseudomonas produce both antibiotics and several other bioactive substances. For example, Pseudoalteromonas rubra and Pseudoalteromonas aurantia have been reported to be antibiotic producing bacteria. The phenomenon of higher organisms utilizing their associated microflora for the production of beneficial secondary metabolites is common in the marine environment (Yotsu, et al., 1987). A study of bacteria isolated from marine algae surfaces indicated that the incidence of antibiotic producing strains from this habitat was 20% whereas that from sea water was only a few percent. In addition, some bacteria that previously did not produce any active compounds have been found to be producing such metabolites when they are exposed to other bacterial species or extra cellular chemical from other bacteria. Bacteria may also produce antimicrobial compounds when they sense the presence of competing organisms. However, few attempts have been made to study such chemical communication between different bacterial species or how this might affect. The secretion of antimicrobial compounds (Mearns-Spragg, et al., 1998). Bacterial communication by the chemical signals for specific function is simply known as Quorum sensing. In which a bacterial population receives input from the environment and elicits an appropriate response (Hiroaki and Kristina. 2003). The term "quorum sensing" describes the ability of a microorganism to perceive and response to diffusible signal molecules. Bacterial cells sense their population density through a sophisticated cell to cell communication system and trigger expression of particular genes. Tne first system of density-dependent regulation was studied in detail with the luminescence of Photobacterium fischeri (formerly known as Vibrio fischeri) by Bassler et al., 1997. Eventually, they discovered that 3-oxo-N-(tetrahydro-2-oxo-3-furanyl) hexanamid or N-3-(oxohexanoyl) homoserine lactone (OHHL) was responsible the agent in the broth that induced luminescence. Followed by this many researchers have confirmed that in Gram negative bacteria acyl-homoserine lactone is responsible for the cell to cell communication system.
