Bibliometric analysis of scientific output on influenza in Mexico, 2000-2012
During the spring of 2009, H1N1 influenza became the first pandemic of the 21st century. In the last years, bibliometrics studies have proliferated seeking to provide data on world research. There are no bibliometric studies in Mexico
Combining a range of different imaging techniques to better understand the roles metals play in biology
Microscopes in various forms have helped identify disease-causing bacteria, miniaturize microprocessors and engineer superior metal alloys. However, in biology some things remain very difficult to see even at the highest levels of magnification. Metal ions (e.g. calcium,
Improvement of critically sized bone fracture healing by using conductive tissue engineering scaffolds
Bone is the second most prevalent transplant tissue after blood. Healing the critically sized bone defects caused by tumor or trauma are among the major challenges for orthopedic surgeons. Although, allografts and autografts are commonly used for
AMPK, an energy consumption supervisor, regulates hedgehog and may be a cancer therapeutic target
A cell can be thought of as a factory with many machines controlling different processes. Cell growth is the process by which a cell divides and multiplies. It is a highly energy-consuming process. Therefore, supervisors are needed
How to get the lowest production of sewage sludge by using ozone
Wastewater needs treatment before discharge into rivers or lakes or to the sea, to avoid pollution of these water bodies and prevent waterborne diseases. Biological processes are usually the core of wastewater treatment plants. In these processes,
Gene therapy: a promising candidate for cystic fibrosis treatment
An improved gene therapy treatment can cure mice with cystic fibrosis (CF). Cell cultures from CF patients, too, respond well to the treatment. Those are the encouraging results of a study presented by the Laboratory for Molecular
Pollen and vegetative microspores as sensitive systems for ozone
The high ground-level ozone concentrations (higher than 0.1 μl/l per hour, in which there is a characteristic odor) is an biggest danger for human health. In environmental biomonitoring of O3 hazardous concentrations in air or chronic levels
A novel miniaturized Reveal LINQ insertable cardiac monitoring system, the guarding angel of your heartbeat
An arrhythmia is a problem with the rate or rhythm of the heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular rhythm pattern. When the heart beats faster than normal, it
Endocrine regulation of Alzheimer’s disease. The Achilles heel of dementia and other neurological conditions
Alzheimer’s disease (AD) is the most common disorder of the central nervous system and the most frequent cause of devastating dementia in the elderly. Typified by loss of memory and by cognitive decline, AD lowers the quality
Extracorporeal life support in polytraumatized patients
Major trauma is a leading cause of death, in particular amongst young patients, causing more than 5 million victims every year worldwide. Early causes of death (usually related to severe hemorrhage, pulmonary failure, cardiovascular shock or extensive
Small fish can help finding antimalarial drugs with less severe side effects
In 2012, over 200 million cases of malaria have been reported. Vaccines for malaria are under development; however, no generally accepted vaccine that also works for adults is yet available. Therefore, drugs will in the foreseeable future
Ultrasensitive detection of influenza viruses by glycan biosensors
These days there is a considerable interest to develop devices, which are able to detect various diseases at early-stage with a high speed and reliability to enhance efficiency of subsequent disease treatment. The first step towards this goal
Relationship quality and sleep
The quality of social relationships and social support appears to be associated with physical health outcomes and sleep quality. Almost all previous research in this area focuses on positive aspects of relationships. In addition to supportive relationships,
Diagnosis of small cell lung carcinoma metastases
Cancer is defined by unscheduled cellular growth and metastatic spread into other organs of the body. Tumor cells gain their capacities form genetic alterations, also known as mutations, leading to altered protein functions and signaling pathways. Tumors
Improved antibody selection with assisting plasmid
When the human body is invaded by foreign molecules, the immune system will be activated to fight against these intruders. This is done with the help of antibodies which act as the defence force of our body.
Origin of photosynthesis: Is photosynthetic ability present in Actinobacteria?
The origin of photosynthesis, which sustains most life on earth, by converting light energy from the sun into chemical energy for plants, animals and other organism, remains an important unresolved problem in the history of life. Besides
Citing in science
A common way to measure the quality of academic research is counting how frequently it is cited. Citation counts are used in making decisions, including hiring and promotion, awarding grants, evaluating academic departments, and purchasing journals. To
Unusual behavior of benzoic acid at low temperature
Molecules of benzoic acid form dimers in the crystal, which is doubly hydrogen bonded through the carboxylic COOH groups (Fig. 1.). Since the left and right site of the dimer are fully equivalent, the protons “do not
Valproic acid treatment for brain tumors
Tumors arising in the brain represent only 2% of all cancers diagnosed in the United States with 23,000 new cases and 14,000 deaths annually. The World Health Organisation (WHO) classifies brain tumors from grade 1 to grade
