(A)Immunotherapy has proven to be effective against many serious diseases. But to treat diseases in the brain, the antibodies must first get past the obstacle of the blood-brain barrier. In a new study, a research group at Uppsala University describes their development of a new antibody design that increases brain uptake of antibodies almost 100-fold.

Immunotherapy entails treatment with antibodies; it is the fastest growing field in pharmaceutical development. In recent years, immunotherapy has successfully been used to treat cancer and rheumatoid arthritis, and the results of clinical studies look very promising for several other diseases. Antibodies are unique in that they can be modified to strongly bind to almost any disease-causing protein. In other words, major potential exists for new antibody-based medicines.

The problem with immunotherapy for diseases affecting the brain is that the brain is protected by a very tight layer of cells, called the blood-brain barrier. The blood-brain barrier effectively prevents large molecules, such as antibodies, from passing from the bloodstream into the brain. It has therefore been difficult to use immunotherapy to treat Alzheimer's and Parkinson's disease, which affect the brain, as well as cancerous tumors in the brain.

It has been known for a long time that some large proteins are actively transported across the blood-brain barrier. These include a protein called transferrin, whose primary task is to bind to iron in the blood and then transport it to the brain. The research group behind this new study has taken advantage of this process and modified the antibodies they want to transport into the brain using components that bind to the transferrin receptor. Then, like a Trojan horse, the receptor transports antibodies into the brain. The number of modifications to and placement of the antibodies have proven to be important factors for making this process as effective as possible.

"We've placed them so that each antibody only binds with one modification at a time, despite being modified in two places. Our design thus doubles the chances of the antibody binding to the transferrin receptor compared with only one modification. We've successfully increased the amount of antibodies in the brain almost 100-fold, which is the largest uptake improvement that has ever been shown." says Greta Hultqvist, researcher at the Department of Public Health and Caring Sciences at Uppsala University.

To try out the new format, researchers have used it on an antibody that binds to a protein involved in the course of Alzheimer's disease. Without the modification, they could only detect very small quantities of antibody in the brain in a mouse model of Alzheimer's disease, while they could detect high levels of the modified antibody in the same mice. "From a long-term perspective, it's likely that the new format can be used to effectively treat not only Alzheimer's disease, but also other diseases affecting the brain," says Dag Sehlin, researcher at the Department of Public Health and Caring Sciences at Uppsala University.

(B)All rocks are not the same, even though many of them look alike. There are three main types or classes of rock: sedimentary, metamorphic, and igneous. The dfferences between each of the rocks have to do with how they are formed. This is what determines the type of rock it is.

The first type of rock is sedimentary. A sedimentary rock is formed from particles of sand, shells, pebbles, and other pieces of material. All of these particles together make up sediment. Sediment is the result of material broken down by weathering or erosion. Slowly, the sediment accumulates in layers and over a long period of time it will harden into rock. Sedimentary rock, usually, is fairly soft and may break apart very easily or crumble into pieces. If sedimentary rock is broken apart inside is sand, pebbles, or stones in the rock. Sedimentary rock is usually the only type of rock that also contains fssis Fossils are the remains of once living animals or plants usually from long ago. Examples of sedimentary rock types include limestone, shale, and sandstone.

The second type of rock is metamorphic. A metamorphic rock is formed under the surface of the earth from the change that takes place because of intense heat or pressure. In nature, it takes millions of years for a metamorphic rock to be formed. The rocks that result from this very long process ofen have rbbonlike layers and many shiny crystals. The crystals are formed by minerals which grow slowly over time on the surface of the rock.

Examples of metamorphic rock types include gneiss, marble, slate, and quartzite. The third type of rock is igneous. lgneous rocks form when magma cools and hardens. Magma is the molten rock deep within the earth. The same material is inside a volcano. Sometimes this magma, though, cools inside the earth. At other times it will erupt onto the surface from a volcano. When magma leaves the volcano it is called lava.

When this lava cools very quickly, no crystals form and the rock will look shiny and glasslike. Sometimes there are gas bbles trapped inside the rock during the cooling process of the magma. If this occurred there will be tiny holes and spaces left in the rock.

Examples of igneous rock types include basalt, obsidian, pumice, and granite. In summary, even though many rocks may look alike, there are three types of rocks with different characteristics. The three types of rocks are sedimentary, metamorphic, and igneous. Sedimentary rocks are formed from sediments that may include particles of sand, pebbles, or other stones. Fossils may also be found in sedimentary rock. Metamorphic rock takes millions of years to form and is formed by intense heat and pressure. They often are ribon-like and contain shiny crystals. The last type is igneous rock, which forms when magma cools and hardens deep inside the earth. Magma is the same material inside of a volcano. AlI three rock types can be found in many places. Some examples of each include limestone, marble, and granite. Rocks are definitely not all the same.

“Ecology" implies a harmonious and interactive relationship between nature and human beings, but the word is often misused. Those who 31 to know ecology do not necessarily understand the essence of ecology, 32 do they follow its principles.“Ecotourism" provides a useful example. It has been frequently 33 by the tourism administration and is familiar to the public. However, when a 34 arises between economic benefit and ecological protection in tourism programs for nature reserves, scenic spots, national parks, and world heritage sites (hereinafter rferred to as “protected areas") 3 in tourism development and management, how ofen do the immediate economic benefits 36 the long-term protection of the ecology? How many tourists prefer a walking eco-tour 37 the comfort and convenience of a tour by modern transport? In fact, the ecotourism curenly discussed dfers lite 38 the traditional tourism model. Garbage cans, public lavatories, and publicity 39 may have been supplemnented by the tourism administration, increasing tourists' 40 not to ltter or pick flowers. While these steps can be defined as clean tourism, they are far from being ecotourism.

46.The psychological efects of color have been of interest to people for a long time. The ancient Egyptians, Chinese, and Indians all used color as part of healing therapies. The psychology of color is still of interest in moderm times. Iterior decorators and web designers all incorporate an understanding of the relationship between color and mood into their work.

In selecting color for an interior space, the designer considers what type of mood is compatible with the activities that will be crried out in that space. At least one study has found that office workers are able to concentrate better in rooms that are painted with cool blues or dark greens. Yellow might be considered suitable for a sales office because it contributes to a positive mood. Restaurants are often painted orange or bright red as it is believed that these colors stimulate the appetite.

The way the Earth interacts with the sun's energy can be displayed in a diagram calledthe Earth's energy budget. It displays the sun's energy that reaches us and how much of that energy is absorbed and reflected by the earth and its atmosphere. Solar energy reaches earthas electromagnetic radiation. Once the energy reaches earth, some of it is absorbed by the atmosphere, including clouds. Some of it makes it to the earth's surface, and is absorbed by land and oceans. The amount of energy absorbed affects temperature. The energy that is not absorbed by the earth or its atmosphere is refleted back out to space in the same wavelengths in which it came to earth.

On average, the amount of energy coming in is equal to the amount of energy going out.So, we say the earth's energy budget is balanced. If more energy was coming in than wasgoing out, the earth's temperaure would increase. On the other hand, if too much energy isreflected, and not absorbed, we'd see a decrease in the earth's temperatures.

Of all of the sun's energy that hits the Earth, about 70% is absorbed by the land, ocean,atmosphere and clouds and about 30% is reflected back into space. Which of the four piecharts correctly shows this relationship?

The Earth's Energy Budget
