| Stem Cells For Nose Surgery? Probably | | 2008-07-15 23:43:00 | | Stem cell research has been on for at least two decades now and has made tremendous headway in biological and other related medical studies.Generally, research utilizes two kinds of stem cells- embryonic and adult stem cells. While human embryonic stem cells (isolated from human embryos) are a largely controversial field, studies continue.Plastic surgery procedures like nose enhancement and corrective nose surgery could benefit from adult stem cells that occur in the adult human body and display the potential to reconstruct lost tissue or grow it non-invasively. Certain reconstructive nose implant procedures make use of synthetic materials like silicone, which could be substituted with inherently cultivated stem cell implants.Over a period of time, soft tissue implants tend to lose at least 40-60 percent of their total volume. Stem cells, on the other hand, once they have generated the final size and shape of the tissue mass (bone, fat, cartilage, etc.) could reta | | By: Nose Surgery Beverly Hills | | |

| Stem Cells Saves Lives | | 2008-07-11 12:01:53 | | Stem cell research is a medical breakthrough technology that has been stormed with a lot of debate in the recent years. Primarily because of the method of collection of the actual stem cells for experimentation. Back in the days, stem cell researchers and scientists use actual human embryos to tinker with. A lot of conservatives have a huge issue with this method because they feel stem cell research is messing with human lives.Things have changed recently. Recent medical technology breakthroughs have allowed researchers to "go around the bend" and continue to experiment with stem cells without the controversy. Cord blood is now used in replacement of human embryos. The cord blood is extracted from the mother's umbilical cord and stem cells are derived from it. The baby is never directly involved.This technology is already here and it does work. Check out this cool touching story of how cord blood banking changed lives of actual families.

| Animal Cells | | 2008-07-02 15:56:00 | | Eukaryotic cells are typically much larger than prokaryotes. They have a variety of internal membranes and structures, called organelles, and a cytoskeleton composed of microtubules, microfilaments, and intermediate filaments, which play an important role in defining the cell's organization and shape. Eukaryotic DNA is divided into several linear bundles called chromosomes, which are separated by a microtubular spindle during nuclear division.Internal membraneEukaryotic cells include a variety of membrane-bound structures, collectively referred to as the endomembrane system. Simple compartments, called vesicles or vacuoles, can form by budding off other membranes. Many cells ingest food and other materials through a process of endocytosis, where the outer membrane invaginates and then pinches off to form a vesicle. It is probable that most other membrane-bound organelles are ultimately derived from such vesicles.The nucleus is surrounded by a double membrane (commonly referred to as a | | By: Biosolution | | |

| Photovoltaic Cells | | 2008-06-13 06:57:45 | | Picture: DOE/EEREPhotovoltaic cells (PVs) (also known as "solar cells") work by transforming light that comes from the sun directly into electricity without an intermediate mechanical device or thermal process. The term photovoltaic is derived by combining the Greek word for light, "phos", with the word "voltaic". The term "volt" is a measure of electricity named for Alessandro Volta (1745-1827), a pioneer in the study of electricity. Photovoltaics literally means light-electricity. The basic building unit of PV technology is the photovoltaic cell (PV cell). PV cells are made of a semiconductor material, typically silicon, which is treated chemically. When light hits the cell, a field of electricity is created within the layers causing the electricity to flow. This "photovoltaic effect" results in direct current (DC) electricity which is the same type of current produced by batteries. In order to use this energy in most homes, an inverter is used to change the DC electricity to AC. Onc | | By: Solar Energy - Green Lifestyle for You | | |

| Bringing PV Cells from Space back down to Earth | | 2008-06-13 06:55:13 | | During the 1960s and early 1970s the use of solar cells in space flourished but down on Earth electricity from the sun seemed not very perspective option. The high costs of the PV cells made them uneconomical for use on the earth where low price is the main factor. In the early 1970's a way to lower to cost of solar cells was discovered. Dr. Elliot Berman, with financial help from Exxon Corporation, designed a significantly less costly solar cell by using a poorer grade of silicon and packaging the cells with cheaper materials. This brought the price down from $100 per watt to around $20 per watt.The energy crises of the 1970s led to a worldwide push for alternative renewable sources of energy, and photovoltaic were seen as a possible solution. Major research activities in the field took place and the main objective of photovoltaic research has been to reduce costs in order to bring solar power to people.Significant efforts were made to develop PV power systems for residential and comm | | By: Solar Energy - Green Lifestyle for You | | |

| Does The Acai Berry Destroy Cancer Cells In Humans? | | 2008-05-29 12:43:00 | | Hundreds of years ago when the Europeans made contact with the new world in the Amazon region, certain indigenous plants became extinct shortly after their arrival due to the lack of resistance to diseases brought over from Europe. Some of the trees that did survive were palm trees that produce the acai berry twice a year.Why did these trees fair so well?This fruit is remarkably rich in a wide range of nutrients and trace elements. The acai palm could also survive when standing submerged in water for up to a year. It is this ability to resist disease and survive that is also passed on to those who consume its fruit. So rich in nutrients are the acai fruit that people could survive on it alone for up to six months before showing signs of malnutrition.One reason so little was known about the acai berries until a few years ago is that they are highly perishable and normally used immediately after picking.

| Red Blood Cells | | 2008-05-19 05:30:00 | | Red blood cells are the most common type of blood cell and the vertebrate body's principal means of delivering oxygen from the lungs or gills to body tissues via the blood.Red blood cells are also known as RBCs, red blood corpuscles (an archaic term), haematids or erythrocytes.Erythrocytes consist mainly of hemoglobin, a complex molecule containing heme groups whose iron atoms temporarily link to oxygen molecules in the lungs or gills and release them throughout the body. Oxygen can easily diffuse through the red blood cell's cell membrane. Hemoglobin also carries some of the waste product carbon dioxide back from the tissues. (In humans, less than 2% of the total oxygen, and most of the carbon dioxide, is held in solution in the blood plasma). A related compound, myoglobin, acts to store oxygen in muscle cells.The color of erythrocytes is due to the heme group of hemoglobin.

| Beta cells (Insulin Production) | | 2008-04-21 20:45:00 | | Beta cells (beta-cells, β-cells) are a type of cell in the pancreas in areas called the islets of Langerhans. They make up 65-80% of the cells in the islets.In mammals, insulin is synthesized in the pancreas within the beta cells (β-cells) of the islets of Langerhans. One to three million islets of Langerhans (pancreatic islets) form the endocrine part of the pancreas, which is primarily an exocrine gland. The endocrine portion only accounts for 2% of the total mass of the pancreas. Within the islets of Langerhans, beta cells constitute 60–80% of all the cells.In beta cells, insulin is synthesized from the proinsulin precursor molecule by the action of proteolytic enzymes, known as prohormone convertases (PC1 and PC2), as well as the exoprotease carboxypeptidase E.

| Scientists Reprogram Human Skin Cells Into Embryonic Stem Cells | | 2008-02-12 02:59:00 | | (HealthDay News) -- U.S. scientists say they've reprogrammed human skin cells into ones with the same blank-slate properties as embryonic stem cells, a breakthrough that could aid in treating many diseases while sidestepping controversy.Human embryonic stem cells have the ability to become every cell type found in the human body. Being able to create these cells en masse and without using human eggs or embryos could generate a potentially limitless source of immune-compatible cells for tissue engineering and transplantation medicine, said the scientists, from the University of California, Los Angeles.The researchers genetically altered human skin cells using four regulator genes, according to findings published online in the Feb. 11 edition of the journal Proceedings of the National Academy of the Sciences.The result produced cells called induced pluripotent stem cells, or iPS cells, that are almost identical to human embryonic stem cells in function and biological structure.

I keep hearing of fuel cell technology being "right around the corner", but had yet to see real production units. Voller Energy seems to actually be producing something that is usable and which you might actually be able to buy when it launches commercially in 2008. Designed to run from LPG, propane or butane, they are already aiming for the marine and RV markets, among others.
This might be a technology that fits well with my timeframe, although costs will be of course interesting.
They recently had one of their pre-production units on a yacht that crossed the Atlantic (it was sail, but they were using the fuel cell for electric power, as I understand it).
