Document Summary

Source problems: literary all our authors are elite males, and therefore present only a certain (very limited) viewpoint. Each literary genre has its own specific problems: satire may exaggerate social ills or situations for its own purposes, for example. Love poets look more favorably on sexual practices than the moralists. Most tend to proscribe the same sorts of sexual activities (such as fellatio). The study of sexual content in ancient art may counteract this prohibition to some degree, and it is one of the course objectives to compare and contrast literary and artistic evidence. Artistic: vase painting there are two kinds of vases or pots, for our purposes: athenian black. Figure and athenian red figure (abf, arf, or black figure/ red figure). Athenian clay turned a warm deep reddish-orange when fired. Pots were made in several pieces (body, spout, foot, handles). The pieces were allowed to partially dry, then put together with slip (clay in liquid form).

Kindly write a one page summary of the data below.

A crucial assumption underlying most models of sexual selection is that sexual advertisements honestly reflect the phenotypic and/or genetic quality of their bearers (1). Here we show that experimental activation of the immune system is rapidly mirrored in the expression of a carotenoid-based secondary sexual trait in male blackbirds (Turdus merula). This result shows that sexual advertisement honestly signals male health and can be reliably used by conspecifics as a cue of individual quality during intra- and/or intersexual interactions. Male blackbirds exhibit a black plumage with a yellow to orange bill, whereas females are brownish with a brown bill. Recent studies have suggested that bill color is a sexually selected trait in blackbirds (2, 3). For example, resident male blackbirds are more aggressive to mounts with orange bills than to mounts with yellow bills (2). Bill pigmentation might therefore provide a signal used during contests between males (2). In addition, male blackbirds with orange bills are mated with females in better body condition and fledge more offspring than males with yellow bills (3). Overall, these results suggest a role for bill color in sexual selection, possibly as an indicator of male phenotypic quality. Carotenoids are common components of colored signals used in animal communication (4). They are also important in the up-regulation of various aspects of the immune functioning (5) and cellular protection against free radicals (6). This suggests that a trade-off may exist between allocation of carotenoids to sexual signaling versus immune defenses (4). Using an autosampler high-performance liquid chromatographer, we determined the presence of carotenoids deposited in the bill of male blackbirds [see note (S1)] (7). The analysis of the absorption spectrum revealed the presence of - and -carotene, -cryptoxanthin, zeaxanthin, and lutein (Fig. 1A). To investigate whether bill color reflects immune status, we immunized captive male blackbirds with a suspension of sheep red blood cells (SRBC) in both spring 1999 (n 19) and spring 2002 (n 13). A control group (n 15) was injected with a phosphate-buffered saline solution (PBS) for control in 2002. Only the 2002 birds were used as a direct test of the hypothesis that immune activation reduces the expression of the secondary sexual trait, by comparing changes in bill color for SRBC and PBS males. Birds immunized with SRBC in both years (n 32) were used to assess the effect of anti-SRBC immune response on bill color [see note (S2)] (7). The humoral immune response against SRBC was determined 7 days after the challenge with a haemagglutination technique. Birds immunized with SRBC displayed a significant decrease in bill color [repeated measurements analysis of variance, F(1,26) 14.34, P 0.0008; Fig. 1, B, C, and D], which was independent of initial bill color and was not associated with a decrease in body mass (P 0.1). In addition, among immunized males, the likelihood of becoming duller was significantly correlated with the intensity of the anti-SRBC response as determined from the haemagglutination test (logistic regression, Wald 2 5.12, P 0.023, n 32), whereas neither year nor initial bill color entered the logistic regression model (P 0.1). Overall, these results demonstrate the existence of a trade-off between sexual advertisement and immune activation in male blackbirds. This finding has important consequences for both the evolution of secondary sexual traits and the cost of immune function. Assessment of opponent quality during male-male competition or mate quality during female choice based on a dynamic trait, such as bill color, might have evolved if it honestly reflects health status of the individual (1). The activation of the immune system by an infectious process is rapidly mirrored in the color of the bill. Contrary to feather ornaments that are produced during the annual molt, dynamic traits might therefore convey a continual update on male health. Carotenoids, such as astaxanthin, lutein, and -carotene, used for sexual signaling have been shown to enhance in vitro and in vivo antibody production to SRBC (8) and to provide protection against free radicals (6). Our results suggest that the activation of the immune system withdraws carotenoids to enhance immune functioning as well as to deal with free radicals produced during the immune response, at the expense of sexual signaling.

Guidelines

Guide only, feel free to organise however else you like to as long as you address the learning outcomes and elements in the rubric.

* Introduction

Introduce the general issue and its importance

Identify key trends or perspectives

Identify the specific focus of this literature review (your identified issue)

Give a brief outline of the structure of the body

* Body

Cluster your literature around common themes or threads of ideas. Structure your writing thematically and not author by author. This allows you to compare, contrast, and make sense of the different authorsâ perspectives on one point./ And if you find there are a lot of authors with some contribution to one point, then maybe that point needs to be teased out into sub-themes

Try not to hide behind what the literature is saying. Remember, it is up to you to interpret it and make sense of it for your reader. Listing what they have found or believe is part of a literature review, but in itself is not enough, you need to clarify what the reader is to take away from this body of research

Never be afraid to narrow your topic. You have a word limit, which is enough to make one meaningful point, but not to include detail for its own sake. It is better to dig deep into a topic rather than be broad and superficial

You may have to limit your question many times before you finalise your draft. Spend time considering your question/topic, because this provides the guidelines for your writing and your research. You need to have clear guidelines so that you can research with purpose and efficiency, even if these guidelines are modified later. Otherwise a lot of time and energy will be wasted, either, looking at irrelevant material, or material that cannot fit into your review

* Conclusion

Summarize the major contributions, evaluating the current position, and pointing out flaws in methodology, gaps in the research, contradictions and areas for further study

Conclude by summing up and identifying the significance of the topic in relation to the literature

* Please ensure that you write succinctly to avoid wasting your word count. Note that unnecessary words weakens your argument. You should keep within +/- 10% of your word count

* Check for spelling and grammatical errors. Loosing marks from errors that could be addressed through editing is not worth it.

* Make sure that all references are correctly referenced using APA style

* Refer to Unit Guide for more information about the unit requirements

Scenario 2:
You are trying to resolve the 3-dimensional organization of some sub-cellular organelle or protein distributed throughout the cytosol of a cell. The objects are typically organized spatially with sizes of ~0.5Î¼m diameters or separation. In this situation the sample can be fixed (i.e. no constraint on image time), but it may be advantageous to image live samples as well (i.e. some constraint on image time), so the ability to image each type of sample needs to be considered. Issues to consider include limits of 3-dimensional spatial resolution and ways to overcome this, including within live moving cells such as time and photodamage effects.

The scenario above describes commonly encountered problems in applying fluorescence microscopy to study biological samples. I would like you to discuss ways of overcoming the problems at hand.

The problems that needs to be overcome:

-What is the cause of the fundamental limitation(s) present in the problem when using a conventional fluorescence microscope system (wide field microscope or regular confocal microscope)? What are the tradeoffs (e.g. photobleaching, acquisition speed, spatial resolution, signal, noise and background, or other factors) that provide practical limitations?

-What type of optical imaging approach, technology or strategy could overcome these problems?

-What light source, optical detector, fluorophore and other key instrumentation/reagents will be needed and why? (you may want to provide specs for specific products where relevant).
-How will this strategy work and how will it generate new information about the object/process being studied: e.g. will fluorescence intensity be measured, or fluorescence lifetime, or scattering, some other property?

-What other limitations could there be in the approach planned? Can these also be minimized and how?
