Using genetically diverse seed sources can improve revegetation outcomes for native flora, as local seed may be inbred and lead to poor results. The review recommends focusing on capturing high-quality seed to ensure restored populations have ample genetic diversity.
A team of researchers used oceanographic data to predict the potential consequences of climate change on a global scale. They found that if current trends continue, altered ocean circulation could lead to dramatic implications for the world's climate and biosphere.
Chronic kidney disease exacts a significant toll on women's sexuality and gynecologic health, with hormonal changes affecting body functions. Experts will explore the impact of CKD on women's sexual life cycle, fertility, and pregnancy from adolescence through menopause.
A study led by Ercan Ok found that overnight hemodialysis reduced mortality rates by 78% and improved blood pressure control, appetite, weight gain, and cognitive functioning among patients. The results suggest longer dialysis regimens as a promising alternative to addressing high risk of death among dialysis patients.
A team of paleontologists from the University of Utah and independent scientists have found no evidence of dinosaur tracks at the 'dinosaur dance floor' site in northern Arizona. Instead, they suggest the features may be unusual potholes eroded in the sandstone.
Research using brain scans at the University of Chicago found that aggressive youth activated neural circuits underpinning pain processing when watching pain inflicted on others. The study suggests some aggressive youths' natural empathetic impulse may be disrupted, increasing aggression.
Individuals with kidney stones are at a 60% greater risk of developing chronic kidney disease (CKD), according to a new study. Researchers recommend careful monitoring of stone formers and appropriate treatment when needed.
Researchers have successfully treated HIV-seropositive women with assisted reproduction, achieving pregnancies and stable infant outcomes. Additionally, studies found that SC Ovidrel can be reliably used for egg-cell donation and pregnancy is possible in breast cancer patients after chemotherapy, despite reduced fertility.
A study of 2025 women who donated kidneys found that female kidney donors do not face increased risks of miscarriage, premature birth or gestational diabetes. While post-donation pregnancies had higher rates of certain health conditions, these were comparable to those in the general population.
Despite its biblical origins, leprosy remains a significant public health concern in the US, with approximately 150 cases diagnosed annually. Early treatment with medicine is crucial for full recovery, but misdiagnosis and lack of awareness among physicians lead to delayed treatment and debilitating damage.
A clinical trial found that cognitive-behavioral therapy significantly improves depressive symptoms and quality-of-life scores in patients with kidney disease on dialysis. After three months of weekly sessions, patients showed a substantial reduction in depression and improved cognitive function.
deCODE's DNA-based tests measure genetic markers linked to increased cardiovascular conditions' risk. These tests provide doctors with a new tool for improving screening, prevention, and treatment.
Researchers found that weakening Asian monsoons may have contributed to the fall of three Chinese dynasties, leading to periods of popular unrest. A strong summer monsoon prevailed during a 'golden age' of rice cultivation and rapid population growth in China.
The recently passed Medicare Improvement for Patients and Providers Act of 2008 will significantly impact nephrology practice and patient care. Key provisions include funding for CKD education sessions, bundled payment systems, and quality measures to improve efficiency and outcomes.
A recent study found that the cost of treating colorectal cancer can range from tens of thousands of dollars, with newer therapies often costing significantly more than older agents. This variation in costs raises questions about access to care and the value of these treatments for patients.
The guidelines provide clinical features, diagnosis, and treatment information for a range of congenital heart defects. They also highlight key issues to look for during follow-up and make recommendations on genetic testing, pregnancy, contraception, and physical activity.
The University of Oregon's College of Education is expanding its special education technical assistance center to help schools foster positive behavior. The $8 million, five-year program aims to implement school-wide positive behavior support in over 15,000 schools and demonstrate its link to improved academic outcomes.
A computer model called Diag was developed to predict human behavior and learning in a circuit troubleshooting task. The model learned at the same rate as participants, replicating their strategy and solving problems accurately.
A revised theory suggests that carbon dioxide levels have already entered a danger zone, necessitating a reduction below current levels of 385 parts per million (ppm). The study concludes that coal is the largest source of atmospheric CO2 and that phasing out its use could lead to a significant decline in CO2 emissions.
Research suggests that vitamin D, specifically its active form calcitriol, could offer protection against radiation-induced damages by regulating cell cycle and proliferation. This could be a potential safe agent for protecting people before or after low-level nuclear incidents.
A new study published in Biology of Blood and Marrow Transplantation demonstrates that a reduced-intensity conditioning bone marrow transplant can eliminate symptoms of sickle cell disease in six out of seven patients. This approach eliminates life-threatening side effects associated with traditional bone marrow transplants.
A newly developed equation estimates glomerular filtration rate (GFR) more accurately than the widely used Modification of Diet in Renal Disease (MDRD) Study equation, especially at higher GFR levels. The CKD-EPI equation was validated using data from over 8,000 patients and shows lower bias compared to the MDRD equation.
A study of over 5,300 live kidney donors found that obesity was common among donors, particularly those from African- and Hispanic-American backgrounds. Obese donors were more likely to develop hypertension prior to and after donation, but did not experience worse kidney function compared to non-obese donors.
T.P. Ma recognized for groundbreaking research in semiconductors, impacting high-tech industry and leading to practical applications such as flash memory. His work has been widely adopted by companies worldwide, including IBM and Intel.
A University of Missouri study finds that analysts' self-interests influence the value of street earnings, leading to upward bias in glamour stocks. This biases makes street earnings less useful for predicting future earnings of high-growth stocks.
Researchers at the American Society of Nephrology's Annual Meeting found that stent placement does not improve kidney function or blood pressure in patients with atherosclerotic renovascular disease. The ASTRAL trial, involving over 800 patients, showed no clinically worthwhile benefits from revascularization.
Researchers Leif Ristroph and Jun Zhang used a tabletop experiment to show that two or more flexible objects in a flow experience drag differently than rigid objects. For example, when one flag flaps, it reduces its own drag but increases the drag on its follower, contrary to expected behavior.
A collaborative study reveals how interactions between common gene variants affect brain function in schizophrenia patients, particularly in working memory. The findings suggest that combining these genetic variations may lead to reduced cortical activity, making them potential new targets for treatments.
A new national survey by Queen's University shows that despite increased investment in infection control since the SARS crisis, the number of resistant bacterial infections has multiplied. The study highlights a need for continued investment in infection control resources and programs to combat the growing threat of superbugs.
