Determine Concentration and Molarity

Determine Concentration and Molarity Molarity is one of the most common and important units of concentration used in chemistry. This concentration problem illustrates how to find the molarity of a solution if you know how much solute and solvent are present. Concentration and Molarity Example Problem Determine the molarity of a solution made by dissolving 20.0 g of NaOH in sufficient water to yield a 482 cm3 solution. How to Solve the Problem Molarity is an expression of the moles of solute (NaOH) per liter of solution (water). To work this problem, you need to be able to calculate the number of moles of sodium hydroxide (NaOH) and be able to convert cubic centimeters of a solution into liters. You can refer to the Worked Unit Conversions if you need more help. Step 1 Calculate the number of moles of NaOH that are in 20.0 grams. Look up the atomic masses for the elements in NaOH from the Periodic Table. The atomic masses are found to be: Na is 23.0H is 1.0O is 16.0 Plugging these values: 1 mol NaOH weighs 23.0 g 16.0 g 1.0 g 40.0 g So the number of moles in 20.0 g is: moles NaOH 20.0 g Ãâ€" 1 mol/40.0 g 0.500 mol Step 2 Determine the volume of solution in liters. 1 liter is 1000 cm3, so the volume of solution is: liters solution 482 cm3 Ãâ€" 1 liter/1000 cm3 0.482 liter Step 3 Determine the molarity of the solution. Simply divide the number of moles by the volume of solution to get the molarity: molarity 0.500 mol / 0.482 litermolarity 1.04 mol/liter 1.04 M Answer The molarity of a solution made by dissolving 20.0 g of NaOH to make a 482 cm3 solution is 1.04 M Tips for Solving Concentration Problems In this example, the solute (sodium hydroxide) and solvent (water) were identified. You may not always be told which chemical is the solute and which is the solvent. Often the solute is a solid, while the solvent is a liquid. Its also possible to make up solutions of gases and solids or of liquid solutes in liquid solvents.  In general, the solute is the chemical (or chemicals) present in smaller amounts. The solvent makes up most of the solution.  Molarity is concerned with the total volume of the solution, not the volume of the solvent. You can approximate molarity by dividing moles of solute by volume of solvent that is added, but this isnt correct and can lead to significant error when a large amount of solute is present.Significant figures can also come into play when reporting concentration in molarity. There will be a degree of uncertainty in the mass measurement of the solute. An analytical balance will yield a more precise measurement than weighing on a kitchen scale, fo r example. The glassware used to measure the volume of solvent also matters. A volumetric flask or graduated cylinder will yield a more precise value than a beaker, for example. Theres also an error in reading the volume, relating to the meniscus of the liquid. The number of significant digits in your molarity is only as many as that in your least precise measurement.

Pegomastax - Facts and Figures

Pegomastax - Facts and Figures Name: Pegomastax (Greek for thick jaw); pronounced PEG-oh-MAST-ax Habitat: Woodlands of southern Africa Historical Period: Early Jurassic (200 million years ago) Size and Weight: About two feet long and five pounds Diet: Plants Distinguishing Characteristics: Prominent fangs; short bristles on body About Pegomastax Some of the most notable dinosaur discoveries dont involve going out into the field with a shovel and pickax, but examining long-forgotten fossil specimens that have been filed away in dank museum basements. Thats the case with Pegomastax, which was recently named by Paul Sereno after he examined a neglected collection of fossils from southern Africa, which had been discovered in the early 1960s and stashed in Harvard Universitys extensive archives. Pegomastax was certainly an odd-looking dinosaur, at least by the standards of the early Mesozoic Era. About two feet long from head to tail, this close relative of Heterodontosaurus was equipped with a parrot-like beak studded by two prominent canines. The porcupine-like bristles that covered its body are reminiscent of the short, stiff, feathery protrusions of another herbivorous dinosaur, the late Jurassic Tianyulong, which was also an early ornithopod of the heterodontosaur family. Given its presumed plant-eating diet, why did Pegomastax have such sizable canines? Sereno speculates that this feature evolved not because Pegoamastax snacked occasionally on insects or rotting carcasses, but because it needed to a) defend itself against larger theropod dinosaurs and b) compete for the right to mate. If longer-toothed males were more likely to survive predation, and also more likely to attract females, you can see why natural selection would have favored Pegomastaxs fangs.

Explaining a recent innovation in your area of interest or expertise Research Paper

Explaining a recent innovation in your area of interest or expertise - Research Paper Example This is a process that has taken to task doctors and scientists worldwide. One of the major setbacks to this work was inadequate finances. Though this is and has been a global problem, states were not able to come together to pool resources so as to support the noble work that the scientists set out to do. It turned out that only few countries provided the financial support to this project, while others showed no interests in the on-going work, yet they too are affected by the virus. The accomplishment was nonetheless realized thanks to the support of the non-governmental organizations and other well-wishers (Grady, 1995). Another great challenge is the fact that the HIV virus replicates very fast, and once it attacks a CD4+ T cell, it quickly makes very many copies of itself. These copies infect other immune cells. Since it makes many copies of itself, it overwhelms the body’s immunity hence weakening the body. This is worsened by the fact that as the replication takes place, there is DNA sequence change that results into different strands of the virus. The vaccine developed should be able to help prevent all these strands. Unlike many other viruses that attack the human body, the primary target of the HIV virus is the immune system, particularly the CD4+ cells. The virus destroys these cells hence making it difficult for the body to protect itself from other infections, even subsequent HIV infections. The vaccine developed therefore has to work to strengthen the system so that the invading virus does not weaken the body, but is able to prepare it to fight off the virus, at the same time leaving the body strong. There are already in existence big companies that manufacture anti-retroviral drugs (ARVs), the drugs currently used to contain the deadly virus. These companies are already making billions in this business and would therefore want to keep making money. An attempt to come up with vaccines is a threat to their business

12 YEARS A SLAVE Essay Example | Topics and Well Written Essays - 500 words

12 YEARS A SLAVE - Essay Example Additionally, the movie talks about the life of an enslaved educated Black man called Northup who later in life turned to abolish slavery in Louisiana. It is a fact that, many Black people have been killed and many have fought back against discrimination and sexual exploitation and these were the martyr’s who should be remembered according to Copleand. In the author’s eye, solidarity and unity is still a big issue for black people as they are mostly struggling to gain respect and acceptance within the white community. The book and film both tells us that, if one looks at history, many black people had taken the courage to fight for their rights and their effort should be taken as guidance by our community. In fact, black people are as valuable as white person from a religious perspective. In her book (Copeland,2010,pg.113) â€Å"Copeland’s theological anthropology assiduously reveals a carefully developed understanding of historic black bodies in relation to the body of Christ† The author in her book recommends that the history of martyr’s should lead the people to fight for solidarity and peace among each other. In the same way, the movie â€Å"Twelve Years of Slave† is a powerful one which communicates to the audience the life of a black slave. The movie is based on the book written by Solomon Northup where the experience of him as a slave is recounted. He was an educated man and stood firm against racial bias of white men in those times. This man can be taken as a role model as he was an educated and free man till his adult times but later turned in to freedom fighter for the slave community in Louisiana. His life was unusual as he was black person who got kidnapped and sold into slavery where he spent twelve long years in pain. Northup can be seen as a martyr as explained by Copeland and should be followed by new generation to find peace and solidarity in their

The Marketing Environment Essay Example for Free

The Marketing Environment Essay The marketing environment surrounds and impacts upon the organization. There are three key elements to the marketing environment which are the internal environment, the microenvironment and the macroenvironment. Why are they important? Well marketers build both internal and external relationships. Marketers aim to deliver value to satisfied customers, so we need to assess and evaluate our internal business/corporate environment and our external environment which is subdivided into micro and macro. Internal Environment The internal environment has already been touched upon by other lessons on marketing teacher. For example, the lessons on internal marketing and also on the functions within an organization give a good starting point to look at our internal environment. A useful tool for quickly auditing your internal environment is known as the Five Ms which are Men, Money, Machinery, Materials and Markets. Here is a really quick example using British Airways. Looking internally at men, British Airways employees pilots, engineers, cabin crew, marketing managers, etc. Money is invested in the business by shareholders and banks for example. Machinery would include its aircraft but also access to air bridges and buses to ferry passengers from the terminal to the aircraft. Materials for a service business like British Airways would be aircraft fuel called kerosene (although if we were making aircraft materials would include aluminium, wiring, glass, fabric, and so on). Finally markets which we know can be both internal and external. Some might include a sixth M, which is minutes, since time is a valuable internal resource.

Analysis of Dickinson’s Pain has an Element of Blank :: Element Blank

Analysis of Dickinson’s Pain has an Element of Blank      Although cryptic in language and structure, Dickinson gives her work an instinctually vivid sense of emotion.   Her examination of the feeling of pain focuses in on only a few of the subtler nuances of pain that are integral parts of the experience.   She draws in on an "Element of Blank" that she introduces in her opening line.   In exploring pain, she proposes that this "blankness" is a self-propagating force that is subject to the dynamic forces of time, history and perception, but only to an extent. Her first mention of "Pain" in the first line does not distinguish this particular emotion as being of a particular brand of pain.   She substitutes no other words for "pain."   By suggesting no other words for "pain," she chooses the most semantically encompassing term for the emotion.   She thus gives her work the responsibility of examining the collective, general breadth of "pain."   Her alternatives offer connotations that color her usage of "Pain": the sense of loss in "grief" and "mourning" or the sense of pity in "anguish" and "suffering."   She chooses the lexical vagueness of "Pain" to embrace all these facets of the emotion.    In introducing the "Element of Blank," it becomes the context that she thus examines pain.   The exact context of "Blank" possesses a vagueness that suggests its own inadequacy of solid definition.   Perhaps this sense of indefinition is the impression that this usage of "Blank" is meant to inspire.   In this context, this "blankness" is suggestive of a quality of empty unknowingness that is supported by the next few lines: "It cannot recollect When it begun."   This inability to remember raises a major problem with respect to the nature of "Pain;" namely whether Dickinson is choosing to personify "Pain" by giving it a human quality like memory, or is in fact negating the humanity of making it unable to remember.   Several lines below, she suggests that "Pain" does in fact possess some sort of limited sentient ability in recognizing "Its Past - enlightened to perceive."   It is very possible that it is the "Pain" that is being enlightened or perceiving. These conscious acts of giving "Pain" some sort of capacity of awareness personify "Pain" to some extent.    In continuation of "Pain's" inability to remember, She proceeds, "It cannot recollect When it begun - or if there were A time when it was not.

“In Praise of Cultural Imperialism” by David Rothkopf Essay

In the article, In Praise of Cultural Imperialism, David Rothkopf illustrates a progressive new world order where information is the new global currency and the United States, â€Å"the indispensable nation,† is the bank. In his article, Rothkopf contrasts the victimizing tendencies of ‘cultural barriers’, which are the unmistakably causing ethnic, religious, ideological, tribal or nationalistic conflicts, to the uniting tendencies of western globalization. Rothkopf predicts the inevitable merging of all the cultures under the common benefits originating from globalization once â€Å"they have realized that to compete in the global marketplace they must conform to the culture of that marketplace† The United States whose policies are evidently â€Å"the best model for the future† will lead this next step in civilization’s evolution, all the while making sure that â€Å"if common values are being developed, they be the values with which Americans are comfortable.† Rothkopf further states that it is in the US’s best interest â€Å"to encourage the development of a world in which the fault lines separating nations are bridged by shared interest† ultimately leading to a more peaceful and tolerant future: â€Å"Globalization is a vital step toward both a more stable world and better lives for the people in it.† Rothkopf, the former Deputy Undersecretary of the Commerce Department under the Clinton Administration and now the president of an international advisory firm, is also an adjunct professor of international and public affairs at Columbia University. Consequently, his views clearly demonstrate a pro-American capitalist’s stance on the issues pertaining to American economics, cultural imperialism and foreign policy. In his article, Rothkopf describes the power of culture and its influence over this new age global environment, with its power to â€Å"bind and to divide in a time when the tensions between integration and separation tug at every issue that is relevant to international relations.† Moreover, he claims that although critics of globalization may condemn the â€Å"homogenizing influences of globalization,† the effects of globalization are more consistently positive than negative. This is because globalization has an integrating dimension to it. Rothkopf believes that the â€Å"United States is in a position not only to lead in the 21st century as the dominant power of the Information Age, but to do so by breaking down the barriers that divide nations–and groups  within nations–and by building ties that create an ever greater reservoir of shared interests among an ever larger community if peoples† This â€Å"removal not only of cultural barriers but of many of the negative dimensions of culture† could only result in stability†¦right? Rothkopf views could be easily dismissed, as an arrogant fantasy-ridden interpretation of the future. However, although many cultures may not see the benefits of melting themselves into an existence that is in every aspect dominated by western values, the influence of American culture on the rest of the world is evident. Whether this influence will or has been completely positive has yet to be proven. Although Rothkopf believes that globalization is the key to a peaceful future whose culturally uniting fundamentals lie with the United States, he underestimates the complex nature of culture and its strength in relation to globalization. Culture is not something that can be simply defined as Webster’s Third New International Dictionary does, nor will it be easily moulded into a tool to be used for the expansion of American interests. Many cultures around the world, such as in the Muslim block, guard their culture and religion with their lives, for culture and religion are one in the same in Islam. As was illustrated on September 11th, many will even sacrifice their lives for causes they perceive threaten the existence of their culture/religion. Another aspect of globalization that Rothkopf does not develop is the apparent social stratification created by globalization. It is arguable that to sustain globalization, cheap labour must readily available. If undeveloped countries become developed and the poor majority become empowered, where will the cheap labour come from? Although Rothkopf may bring attention to the overbearing extension of American cultural values over the globe, he underestimates how the rest of the worlds’ varied and contrasting cultural values will effect the global environment. Consequently, his extremely biased perspectives undermine some of the more valid points of his article.

The History of Juneteenth Celebrations

The History of Juneteenth Celebrations Abolitionists such as Frederick Douglass and Sojourner Truth worked tirelessly to free blacks from bondage in the United States. And when President Abraham Lincoln signed the Emancipation Proclamation on Jan. 1, 1863, it appeared that the peculiar institution known as slavery had met its end. For many African Americans, life remained the same, however. That’s because fierce racial discrimination prevented them from living autonomous lives. More shockingly, some enslaved African Americans had no idea that President Lincoln had signed the Emancipation Proclamation, which mandated that they be set free. In Texas, more than two-and-a-half years passed before slaves received their freedom. The holiday known as Juneteenth Independence Day honors these slaves as well as African-American heritage and the contributions blacks have made to the United States. History of Juneteenth Juneteenth marks the date of June 19, 1865, when Gen. Gordon Granger of the Union Army arrived in Galveston, Texas, to demand that the slaves there be set free. Texas was one of the last states where slavery endured. Although President Lincoln signed the Emancipation Proclamation in 1863, African Americans remained in bondage in the Lone Star State. When Gen. Granger arrived in Texas, he read General Order No. 3 to Galveston residents: â€Å"The people of Texas are informed that, in accordance with a proclamation from the Executive of the United States, all slaves are free. This involves an absolute equality of personal rights and rights of property between former masters and slaves, and the connection heretofore existing between them becomes that between employer and hired labor. The freedmen are advised to remain quietly at their present homes and work for wages.† Following Granger’s announcement, the formerly enslaved African Americans broke into celebration. Today that celebration, said to be the oldest black American holiday, is known as Juneteenth. African Americans not only celebrated their freedom, they exercised their new rights by buying land across Texas, namely Emancipation Park in Houston, Booker T. Washington Park in Mexia and Emancipation Park in Austin. Past and Present Juneteenth Celebrations The first massive Juneteenth celebrations kicked off the year after Gen. Granger appeared in Galveston. Historic Juneteenth celebrations included religious services, readings of the Emancipation Proclamation, inspirational speakers, stories from former slaves and games and contests, including rodeo events. Many African Americans celebrated Juneteenth in the same way that Americans generally celebrate the Fourth of July. Today, Juneteenth celebrations feature similar activities. As of 2012, 40 states and the District of Columbia recognize the Juneteenth holiday. Since 1980, the state of Texas has observed Juneteenth as an official holiday known as Emancipation Day. Contemporary celebrations of Juneteenth in Texas and elsewhere include parades and street fairs, dancing, picnics and cookouts, family reunions and historical reenactments. Moreover, President Barack Obama pointed out in his 2009 proclamation of the holiday that Juneteenth â€Å"also serves as a time for reflection and appreciation, and an opportunity for many people to trace their family’s lineage.† While African Americans widely celebrate Juneteenth today, the popularity of the holiday has waned during certain periods, such as World War II. Holiday celebrations of Juneteenth resurrected in 1950, but by the last years of that decade and in the 1960s, Juneteenth celebrations declined once more. Juneteenth became a popular holiday again in a variety of regions during the 1970s. In the early 21st century, Juneteenth is not only a well celebrated holiday, there’s a push to have the 19th of June become a National Day of Recognition for slavery. Call for National Day of Recognition The Rev. Ronald V. Myers Sr., founder and chairman of the National Juneteenth Holiday Campaign and the National Juneteenth Observance Foundation, has asked President Barack Obama to â€Å"issue a presidential proclamation to establish Juneteenth Independence Day as a National Day of Observance in America, similar to Flag Day or Patriot Day.† As an elected official in Illinois, Barack Obama supported legislation for his state to recognize Juneteenth, but the president has yet to make a move that would make Juneteenth a National Day of Recognition. Only time will tell if Juneteenth and the slavery of African Americans is ever acknowledged by the federal government in such an official capacity.

Down With the Five Paragraph Essay!

Down With the Five Paragraph Essay! Writing essays is a skill that will serve kids well throughout their lives. Knowing how to present facts and opinions in an interesting, understandable way is valuable regardless of whether they attend college or go directly into the workforce.   Unfortunately, the current trend  is to focus on a type of writing called the Five Paragraph Essay. This fill-in-the-blank style of writing has one main goal - training students to write essays that are easy to grade in the classroom and on standardized tests. As a homeschooling parent, you can help your children learn to produce informational writing that is meaningful and alive.   The Problem with the Five Paragraph Essay In the real world, people write essays to inform, persuade, and entertain. The Five Paragraph Essay allows writers to  do that but only in a limited way. The structure of the Five Paragraph Essay consists of: An introductory paragraph that states the point to be made.Three paragraphs of exposition that each lay out one point of the argument.A conclusion that sums up the essays content. For beginning writers, this formula can be a good starting place. The Five Paragraph Essay can help young students get beyond the one-paragraph page, and encourage them to come up with multiple facts or arguments. But beyond fifth grade or so, the Five Paragraph Essay becomes an obstacle to quality writing. Instead of learning to develop and vary their arguments, students remain stuck in the same old formula. According to Chicago Public School English teacher Ray Salazar, The five-paragraph essay is rudimentary, unengaging, and useless. SAT Prep Trains Students to Write Poorly The SAT essay format is even worse. It values speed over accuracy and depth of thought. Students are conditioned to turn out a large number of words quickly, rather than to take the time to present their arguments well. Ironically, the Five Paragraph Essay works against the SAT essay format. In 2005, Les Perelman of MIT found that he could predict the score on an SAT essay solely on the basis of how many paragraphs it contained. So to get a top score of six, a test taker would have to write six paragraphs, not five. Teaching Informational Writing Dont feel you need to assign your children school-type writing projects. Real-life writing is often more valuable and more meaningful to them. Suggestions include: Keep a journal. Many kids enjoy keeping a journal or notebook to capture their thoughts. It can be something to share with you (some teachers use journals to communicate with their students; you can do the same) or a private record. Either way provides useful writing practice.Start a blog. Even reluctant writers can become enthusiastic when writing has a purpose. Writing for an audience provides purpose. There are many options for starting a free blog and privacy features offer parents and students control over who reads the content.Write a review. Ask your kids to review their favorite books, video games, movies, restaurants -  the list is endless. Unlike most school-type reports, reviews have to be written with the audience in mind, and they have to be entertaining. They also help kids learn to express opinions and present valid arguments to the reader.Do a research paper. Give your kids essay-writing a purpose by integrating it into a history project or science topic. Let them c hoose an area that interests them and explore it in depth. Writing research papers also gives students practice in critical thinking and evaluating and crediting source material.

Virtual Teams. Eastern Europe Assignment Example | Topics and Well Written Essays - 750 words

Virtual Teams. Eastern Europe - Assignment Example A good way to determine which are best investment locations within Eastern Europe is by comparing the gross domestic product per capita of the Eastern European countries. The countries with the top three gross domestic products per capita in Eastern Europe are Slovenia, Czech Republic, and Slovakia. The corresponding gross domestic product per capita of each of these countries is illustrated in the table below. Country Gross domestic product per capita Slovenia $27,149 Czech Republic $21,028 Slovakia $17,630 (Globalpropertyguide). The country with the highest gross domestic product per capita could be considered the most attractive location by a lot of business analyst because the customers in that country have higher buying power. Another important variable to consider are the market and industries that the country has to offer. In Slovenia the service industry accounts for 64% of Slovenia gross domestic product and manufacturing and mining are key economic sectors (CultureGrams). T he majorities of companies in Slovakia are state control which leads to a lot of inefficiencies. Tourism in the Czech Republic is a booming industry. The Czech Republic is the best selection among the different Eastern European nations. This country has a diversified industry segment which includes glass, metallurgy, machinery and equipment, motor vehicles and armaments (CultureGrams). The use of virtual teams can help companies achieve better business results. The target country the company selected is the Czech Republic. Since the company does not have any experience in the Czech Republic marketplace the firm should contract a consultant to help them in the process of selecting the virtual team. A local firm that specializes in human resources would be very helpful to access the local talent for the virtual team. The team is going to be composed of 8 people. The company is going to include two managers from its corporate headquarters. The remaining six members will be selected amo ng the local population. Each member will have different academic backgrounds. The six professionals the company will select for the virtual team include an engineer, accountant, marketing specialist, researcher, lawyer, and a scientist. The virtual team will work together to analyze the best business opportunities available in the Czech Republic. The goal of the firm is to achieve market growth by expanding into other markets. The virtual team will utilize multiple technological tools and devices to communicate with each other. The online service Skype will be used as the primary communication tool for team meetings. Skype allows people to communicate while at the same time seeing a video stream of the person. All team members will have smartphones. A smartphone such as an Iphone enables its users to transfer data files from phone to phone. One of the cultural differences between the United States and the Czech Republic is the fact that in the United States the official language is English and the Czech Republic the official language is Slavic. It is important for the American members of the virtual team to understand the customs and traditions of the Czech Republic. For instance in the Czech Republic it is customary go greet a person by shaking hands firmly and saying their last names. In the virtual setting the managers must remember to use the last names of the person. First names are only used among relatives and family members. Another sign of respect in the workplace is addressing both men and women by their professional title. The probability of success of the team depends on a lot of factors. One of the most important aspects of the virtual team project is to have excellent communications among the team

EXPRESSION ON B CELLS IN HEALTHY INDIVIDUALS AND IN CHRONIC Literature review

EXPRESSION ON B CELLS IN HEALTHY INDIVIDUALS AND IN CHRONIC LYMPHOCYTIC LEUKIMIA - Literature review Example Components of the immune system such as the white blood cells protect the body through the creation of specific antigens. However, in some cases, the immune system itself can be a source of problems, such as in autoimmune diseases, where the immune system recognizes cells of the host body as invaders and attacks these. The cells that form an important part of the immune system can also function incorrectly. Chronic lymphocytic leukemia (CLL) is one example of a disorder where the cells of the immune system are functioning incorrectly. This is a cancer where the B cells of the immune system are highly activated, show increased levels of proliferation and decreased rates of apoptosis. This results in the accumulation of affected cells, which prevents the immune system functioning normally. This review considers the role that Toll-like receptors (TLRs) have on immune system functioning, with a specific focus on CD180 (also known as RP105) and its role on CLL. Toll-like Receptors The imm une system plays a crucial role in protecting the body against pathogens and allows the body to effectively defend itself. One class of molecules that have been shown to have an important role in the effectiveness of the immune system is Toll-like receptors (TLRs). ... Image from Akira et al. (2001) However, while the TLR pathway has been shown to be crucial for the defense and protection of the body, it also can have a significant role in immune system diseases and allergies. This can be due to high levels of signaling or deficiencies of molecules that are involved in the signaling pathway . Thus, TLRs play a significant role in the immune system and related diseases. Understanding their functions both collectively and individual is important to understand the occurrence and progression of many different diseases, as well as looking for treatment for these. Studies have revealed that one potentially important TLR in many immune system diseases is CD180, also known as RP105. This molecule is expressed on the outer membrane of B cells that is known to be a leucine-rich repeat (LLR). LLRs are known to be important in the way in which pathogens within the immune system are recognized. A homolog of the protein has been found on mouse B cells, and has b een associated with a decreased rate of cell death. Experimental evidence shows that cells that were negative for CD180 were susceptible to apoptosis induced by corticosteroids, while those that expressed CD108 were not . In mice, almost all mature B cells expressed CD180; however, this is not true in humans. For example, in individuals suffering from systemic lupus erythematosus (SLE) almost 16% of patients tested were not expressing CD180 in a significant quantity. Individuals who did not have SLE had a significantly lower average level of CD180 expression than those who were affected with SLE . In humans, CD180 is involved in the recognition of B cells and signaling of lipopolysaccharides. However, little more is known about its function . In mice, almost all
