...Course: Bio 102 Instructor: Marina Yoffe Assignment: Lab report (Introduction and discussion) Introduction The way in which different organisms acquire oxygen in exchange for carbon dioxide has truly evolved. The exchange of carbon dioxide for oxygen is essential for the survival of organisms that need to produce the energy molecule ATP through the process of cellular respiration. Respiration (breathing) is the way organisms exchange gases with their environment (White and Campo 2004). During cellular respiration organisms break down energy rich macromolecules such as starch to make ATP in a chemical reaction where oxygen and water is involved (Ege R. and A. Krogh 1914).The use of oxygen is very important; therefore the efficient acquisition of oxygen is very necessary for an animal’s survival. Depending on what type of organism is involved, our sources of oxygen are different and occur through diffusion. Terrestrial animals obtain oxygen through the air while organisms living in water depend on the oxygen from the water. Unlike terrestrial animals, the amount of oxygen for animals living in water is limited based on the amount of oxygen that has dissolved in the water. Since an adequate amount of oxygen is necessary, animals developed respiratory organs to help them ventilate and obtain as much oxygen from their respected sources as possible (W.C and R. Oesting 1934). One organism that has developed an efficient way of acquiring oxygen is fish. Fish use a counter-current exchange...

...science and technology of SPM. AFM and SFM have been also newsworthy items in Science and Nature in the past year [14••,15•–17•,18••,19]. An introduction to AFM is covered well in a recent issue of Current Opinion in Chemical Biology, which describes and illustrates the design and mode of operation of AFM [4••]. The AFM images sample surfaces by raster-scanning a sharp tip back and forth over the surface. The tip is on a cantilever that responds to height changes on the sample surface in a way that generates a topographical map of the surface. We build on this excellent introduction by presenting some of the many advances in SPM that have occurred since that review was written. (The accompanying images are from AFM research in the authors’ lab). Atomic force microscopy imaging Proteins Entropic brush...

MS2 is still an efficient method of viewing the mechanisms of mRNA localization in living cells. Boireau S, Maiuri P, Basyuk E, de la Mata M, Knezevich A, Pradet-Balade B, et al. The transcriptional cycle of HIV-1 in real-time and live cells. J. Cell Biol 2007; 179:291–304. This article is interested in looking at the activity of RNA polymerase II by using the transcription of the human immunodeficiency virus type 1 (HIV-1) to examine the synthesis of mRNA at specific transcription sites. HIV-1 works by transcribing high levels of the virus while only allowing the infected cell to transcribe little to none of its own viral RNA. This research sought to give insight on the lack of knowledge when it comes to looking at how transcription works in living cells....

Both plants and some plant pathogens can produce IAA to modulate plant growth. Although the genes and biochemical reactions for auxin biosynthesis in some plant pathogens are well understood, elucidation of the mechanisms by which plants produce auxin has proven to be difficult. So far, no single complete pathway of de novo auxin biosynthesis in plants has been firmly established. However, recent studies have led to the discoveries of several genes in tryptophan-dependent auxin biosynthesis pathways. Recent findings have also determined that local auxin biosynthesis plays essential roles...

...amounts of radiation can be passed on to the offspring of the exposed individual, which is useful in understanding the genetic change of P. aeruginosa. Wright states that gene frequency shifts are not controlled by selection, but rather that the population is split into small subpopulations. This work conducted by Wright can be used to explain the population diversity and quick evolution of P. aeruginosa. CF patients that are exhibiting chronic infections of the airway usually have the multidrug efflux genes mutated. The most common gene mutated is mexZ, a negative controller of the mexY and mexX, which makes up the MexXY-OprM efflux pump7. Using PCA, principle component analyses, to examine two strains, P. aeruginosa wild type from a lab and in vivo strains of P. aeruginosa, higher growth displayed lower productions of the two types of proteases LasA and LasB. These results showed that the phenotypes of the two strains were not correlated6. Due to the work of Beadle, Tatum, Mitchell, and the rest of the team, the scientific community is now able to understand the mechanisms of how genes act and allowed for the understanding of the mexZ gene as well as the LasA and LasB proteases. Treatment of CF is still on an ongoing process. However, there have been significant breakthroughs regarding treatment processes. The use of PTC124 on CF patients with nonsense mutations has shown to reduce the effects that are caused by the CFTR gene9. Another oral treatment, administering...

...Sanil Modi Biol-4910 Summer 2014 M-F Dr. De Vries, Christopher T. Fields The Effects Of Toll Like Receptor 2 Deletion on Social Behavior Neural Network Introduction During this past summer I had the opportunity to conduct research at the Neuroscience Institute at Georgia State University. The research I participated in was under Christopher T. Fields who is working on getting his doctorial degree. In these last few months I have worked on many exiting projects, learned how create experiments and analyze them. From the first day of lab I learned to work with many different lab instruments, software and mastered the structures of the mice brain. The instruments I started working with were a digital microscope and its software Stereo Investigator that took pictures at HD quality of mice brain. Shortly after came the analysis of the pictures we captured and the software used was ImageJ and Excel. In ImageJ you can measure different thresholds of the mice brain and get analysis which is imputed into excel and then the numbers from excel are put into a statistical software where graphs are made and you can check if your experiments had any change from the control. What I also learned was how mice brains are put on a slide. First you would use a cryostat, which slices the mice brain at the amount of thickness needed. While you are slicing the mice brains you are putting them onto a slide. Then they are taken from the slide put into a buffer solution, which lets you add to another...

However, tight glycaemic control, with its inherent risk of hypoglycaemia, is required to prevent the microvascular and macrovascular complications of the disease. While islet or pancreas transplantations offer a longer-term cure, their widespread application is not possible, primarily because of a lack of donor tissue, the burden of life-long immunosuppression, and eventual graft rejection. The rapid increase in the incidence of diabetes has promoted the search for alternative cell-based therapies. Here we review recent advances in the directed differentiation of both endocrine and non-endocrine progenitors towards an islet-like phenotype.

Sreekrishnan b, Sangeeta Kohli c, Vineet Rana a Centre for Rural Development & Technology, I.I.T., Delhi 1100016, India Department for Biochemical Engineering & Biotechnology, I.I.T., Delhi 1100016, India c Department of Mechanical Engineering, I.I.T., Delhi 1100016, India Received 31 July 2003; received in revised form 18 August 2003 Abstract Biogas, a clean and renewable form of energy could very well substitute (especially in the rural sector) for conventional sources of energy (fossil fuels, oil, etc.) which are causing ecological–environmental problems and at the same time depleting at a faster rate. Despite its numerous advantages, the potential of biogas technology could not be fully harnessed or tapped as certain constraints are also associated with it. Most common among these are: the large hydraulic retention time of 30–50 days, low gas production in winter, etc. Therefore, efforts are needed to remove its various limitations so as to popularize this technology in the rural areas. Researchers have tried different techniques to enhance gas production. This paper reviews the various techniques, which could be used to enhance the gas production rate from solid substrates.

...control. Taxol have different effect on growth of tip and distance travelled by nuclei. Moreover, the rate at which the nuclei displace and growth of the tips are dependent on the medium and not on each other. Thus, the results conclude that drug effected fungus affects the tip growth rate and nuclei displacement. INTRODUCTION The purpose of the experiment is to study the hyphal tip growth, and to observe the effects of a drug on the tip growth and the nuclei position of a fungal hyphae. The fungus used in the study is Neurospora crassa, a common red bread mold of Europe and America and was originally obtained from sugar-cane bagasse near New Orleans (Shear and Dodge 1927). It is a common model organism in biology, genetics, cell biology labs, and in research. Because it is quickly reproducing, is easy to culture and can survive on minimal media. Moreover, microtubules and actin are cytoskeletal filaments responsible for structural support for fungus tip, and help in replication of the cell. Actin filament helps tip to grow by polymerizing, so actin subunit comes together form branch-like structure at the tip is called hyphae (Rosenblum and Shivers 2000). The drug was used in this experiment was Taxol, an anticancer drug extracted from the Taxus brevifolia; type of plant which came from family of pacific yew tree (Schiff and Horwitz 1980). Taxol is a drug that inhibits actin filaments to form, it depolymerizes the actin filament, so actin subunit don’t bind together, so actin...
