Elevated levels of C-reactive protein appear associated with psychological distress, depression

CHICAGO – Elevated levels of C-reactive protein, a marker of inflammatory disease, appear to be associated with increased risk of psychological distress and depression in the general population of adults in Denmark, according to a report published Online First by Archives of General Psychiatry, a JAMA Network publication.

Study examines overuse of ambulatory health care services in United States

CHICAGO – An analysis of nationally representative survey data found significant improvement in the delivery of underused care, but more limited changes in the reduction of inappropriate care in ambulatory health care settings between 1998 and 2009, according to a report published Online First by Archives of Internal Medicine, a JAMA Network publication.

Children with chronic conditions increasingly use available resources in children's hospitals

CHICAGO – Children with chronic conditions increasingly used more resources in a group of children's hospitals compared with patients without a chronic condition, according to a report that analyzed data from 28 U.S. children's hospitals between 2004 and 2009, and is being published Online First by Archives of Pediatrics & Adolescent Medicine, a JAMA Network publication.

Bumblebees do best where there is less pavement and more floral diversity

AUSTIN, Texas — Landscapes with large amounts of paved roads and impervious construction have lower numbers of ground-nesting bumblebees, which are important native pollinators, a study from The University of Texas at Austin and the University of California, Berkeley shows.

The study suggests that management strategies that reduce the local use of pavement and increase natural habitat within the landscape could improve nesting opportunities for wild bees and help protect food supplies around the word.

NYU biologists identify proteins vital to chromosome segregation

New York University biologists have identified how a vital protein is loaded by others into the centromere, the part of the chromosome that plays a significant role in cell division. Their findings shed new light on genome replication and may offer insights into the factors behind the production of abnormal numbers of chromosomes.

Their findings appear in the latest issue of the journal the Proceedings of the National Academy of Sciences.

Enzyme accelerates malignant stem cell cloning in chronic myeloid leukemia

An international team, headed by researchers at the University of California, San Diego School of Medicine, has identified a key enzyme in the reprogramming process that promotes malignant stem cell cloning and the growth of chronic myeloid leukemia (CML), a cancer of the blood and marrow that experts say is increasing in prevalence.

The findings are published in the Dec. 24 online early edition of the Proceedings of the National Academy of Sciences (PNAS).

Amazon deforestation brings loss of microbial communities

AMHERST, Mass. – An international team of microbiologists led by Klaus Nüsslein of the University of Massachusetts Amherst has found that a troubling net loss in diversity among the microbial organisms responsible for a functioning ecosystem is accompanying deforestation in the Amazon rainforest.

Why some grasses evolved a more efficient photosynthesis and others didn't

PROVIDENCE, R.I. [Brown University] — Even on the evolutionary time scale of tens of millions of years there is such a thing as being in the right shape at the right time. An anatomical difference in the ability to seize the moment, according to a study led by Brown University biologists, explains why more species in one broad group, or clade, of grasses evolved a more efficient means of photosynthesis than species in another clade did.

Their findings appear this week in the Proceedings of the National Academy of Sciences.

Deforestation in the Amazon equals net losses of diversity for microbial communities

Research from an international team of microbiologists has revealed a new concern about deforestation in the Amazon rainforest – a troubling net loss in the diversity among the microbial organisms responsible for a functioning ecosystem.

Mount Sinai survey shows that nearly 1 in 3 children with food allergies experience bullying

Nearly a third of children diagnosed with food allergies who participated in a recent study are bullied, according to researchers at the Icahn School of Medicine at Mount Sinai. Almost eight percent of children in the U.S. are allergic to foods such as peanuts, tree-nuts, milk, eggs, and shellfish.

Nearly half of parents surveyed (47.9 percent) were not aware of the bullying—although both the bullied children and their parents reported experiencing higher stress levels and lower quality of life.

Chinese medicine yields secrets to scientists at The Scripps Research Institute

LA JOLLA, CA – December 23, 2012 – The mysterious inner workings of Chang Shan—a Chinese herbal medicine used for thousands of years to treat fevers associated with malaria—have been uncovered thanks to a high-resolution structure solved at The Scripps Research Institute (TSRI).

Understanding cell organization to tackle cancer

Scientists at The University of Manchester have identified how cells know which way up they need to be. The discovery could help in the fight against cancer because in the early stages of the disease the cells become disorganised.

Research sheds new light on mechanisms of T-ALL, a form of leukemia that primarily affects children

Acute lymphatic leukemia (ALL) is the most common cancer in children under the age of 14 years. With optimum treatment, approximately 75 % of children are currently cured, but the treatment consists of severe chemotherapy with many side effects. In collaboration with international research teams, scientists at VIB, KU Leuven and UZ Leuven have identified new genetic mutations that lead to T-ALL, a variant of ALL. They have unmasked the ribosome – the molecular machine in the cell that is involved in the production of proteins – as a weak spot in leukemia cells.

3 new genetic links to colorectal cancer

Vanderbilt-Ingram Cancer Center investigators have identified three new genetic "hotspots" linked to colorectal cancer.

These variants, reported Dec. 23 in an Advanced Online Publication in Nature Genetics, provide new insight into the biology of colorectal cancer – and could represent new therapeutic targets for the disease.

OpGen announces sequence assembly and finishing of first reference genome of domestic goat

Gaithersburg, Md.—December 23, 2012— OpGen, Inc. today announced its ARGUS® Whole Genome Mapping System technology was used in combination with next-generation sequencing (NGS) to produce the first, high-quality reference genome of the domestic goat.
