Prenatal Test and Miscarriage

...f tissue from the placenta. These samples are then cultured and chromosomes analyzed to determine abnormalities associated with Down syndrome and other genetic diseases such as cystic fibrosis, Tay-Sachs disease, and sickle cell disease. CVS can be performed at an earlier gestation period (10-12 weeks) than...

Community-associated MRSA: Most Common Cause Of Skin Infection

...red and painful, and have discharge. Researchers cultured the acute skin or soft-tissue infections of 422 patients seen at 11 metropolitan emergency rooms in the United States during August 2004. Out of those patients, 249, or 59 percent, were found to have MRSA. The proportion of infections caused by MR...

Cellular System Causing Destruction Of Faulty Proteins In Cystic Fibrosis Identified

...entists have known for some time that treatment of cultured cells with compounds known as chemical chaperones can increase the fitness of misshaped CFTR and get it into proper shape. Thus, "If we can figure out how to get CFTR into the right shape, we can cure the disease," Cyr said. To better understand h...

A Mushroom Extract May Impact the Body’s Immune Syste

... taken from nine healthy human volunteers and were cultured in vitro. The immune cell samples were treated under three different conditions: one set with no treatment, which served as the negative control; another set treated with the PSK mushroom extract; a third set treated with phytohemagluttin (PHA), a mi...

UCLA Researchers Transform Stem cells From Fat tissues Into Smooth Muscle

...f Medicine at UCLA. Rodriguez and her team first cultured the adipose-derived stem cells in a growth factor cocktail that encouraged the cells to transform into smooth muscle cells. Researchers observed the genetic expression and development of proteins, which are specific to this type of cell. So it looked...

Targeting PARP1 Is Effective In Protecting HD Cells from Damage

...y in an in vitro assay. However, when tested using cultured human and rat cells, only one of the candidate molecules, K245-14, successfully prevented the death of cells in which PARP1 had been overactivated. The next assays examined whether blocking PARP1 activity with K245-14 could reduce energy depletion in...

A three-dimensional Culture System ensures Female Fertility

...or, proving that the births were the result of the cultured embyros. Both male and female offspring were fertile. Source: Eurekalet...

Suitable Culturing Medium, essential for Stem Cell Development

...ts where adult stem cells are taken from patients, cultured and transplanted into damaged brain environments to restore functions lost to disease or injury. ‘We largely keep the brain cells we are born with for life, but we also have stem cells in our brain that can divide and make new neurons for maintenan...

T-cells Developed from Human Embryonic Stem Cells

...pbyrecent.shtml. In their study, the researchers cultured human embryonic stem cells, which were incubated on mouse bone marrow support cells, which in turn converted them into blood forming cells. Those cells were then injected into a human thymus gland that had been implanted in a mouse, and the thymus th...

Researchers Have Linked Rett Syndrome to Mitochondrial Gene

...rial defects, the team overproduced the protein in cultured neuronal cells. They isolated mitochondria and rep...energy production tests. The mitochondria from the cultured cells behaved like the mutant brain mitochondria. "What we wanted to know is if the overexpression o...

In-Vivo Gene Therapy Technique to Cure XSCID in Basset Pups

...ls were taken out of the body of the affected boy, cultured in vitro for five days with exposure to a retroviral vector containing the normal gene and transplanted back into the patient. Three of the boys unfortunately developed a T-cell leukemia attributed to the gene therapy resulting in the cessation of t...

Receptor for H.pylori Identified in Stomach

...discovered that H. pylori induce DAF expression in cultured gastric epithelial cells and that mice lacking DAF develop attenuated stomach inflammation. ‘Our results indicate that H. pylori can co-opt a host protein as a receptor and that it can increase expression of this receptor in gastric epithelial cell...

Understanding how humans detect sweet taste

...tion conducted a series of molecular studies using cultured cells expressing the human sweet taste receptor to understand how it can act both as a sweetener and as a sweet inhibitor. The molecular mechanism revealed that at lower concentrations, sweeteners activate the sweet taste receptor. This is done by at...

Mouse Models To Determine The Cause Of Aggressive Leukemia

... in the bone marrow enhancing the proliferation of cultured leukemic cells removed from the mice and made the cells resistant to imatinib’s growth inhibitory effects. It binds to receptors on the surface of lymphocytes, which triggers the activity of the JAK kinases. This later stimulates cell growth through ...

Fat Cells Can Trigger Heart Diseases

...ion of these vessels. The researchers isolated and cultured these cells, known as epicardial adipocytes, and compared them with cells taken from other fat tissue. The tests showed that these epicardial adipocytes tended to release far greater amounts of cytokines that were potentially more harmful and could p...

A New Bioactive Cement For Facial Reconstruction the future

...eriments, in practice the surgeons would use cells cultured from patient samples. The natural polymer beads help by not only creating pores in the hardened cement, they also protect the cells during the 30 minutes required for the cement to harden. They are planning to develop methods in future for improving ...

Mass Spectrometry to Identify Viruses

...t because of the fact that the norovirus cannot be cultured outside the human body. This could be a significant step towards the use of mass spectrometry as an environmental surveillance tool in detecting pathogenic human viruses in complex environmental samples....

Islet cells producing insulin cultivated in the lab

...anner." Behie and colleagues reported they have cultured human cells that are believed to be good candidates for generating islet cells that can make insulin. The successful growth and characterization of these functional islet cells in the lab led to the conclusion that they may be suitable for treatin...

Infections Of The Oral Cavity Can Be Treated By Photodynamic Therapy

...DA approved drug was added to the biofilms and the cultured samples, followed by which the treated samples were exposed to varying degrees of light (light of a specific wavelength, but of different intensities). In less than 15 minutes, PDT was found to destroy nearly 99.9% of the S. mutans bacteria. Signific...
