A “selfish ribosome” as the origin of cellular life
Could there have been a form of “life” that integrated genetic information, protein translation, and the molecular machinery necessary to replicate itself before the first cells? Might such an entity still exist within our cells as a
Development of thermoelectric gas sensor for breath analysis: How can we improve the gas selectivity?
Breath gas contains a range of marker gases that can be associated with disease and metabolism. For instance, the monitoring of breath H2 is useful for measurement of orocecal transit time, colonic fermentation, abnormal fermentation and irritable
How does exercise reduce the intake and preference for high fat, high sugar foods?
People gain weight because they eat too much food, particularly food with a lot of fats and sugars, and do not use the calories gained from food. In this case the energy intake is higher than energy
Chemistry of wonderful wet laundering
We use two types of laundries. One is dry-cleaning which is carried out using an organic solvent, and another is wet laundering is carried out using water and soap (surfactant). These observations are scientifically applied for the
Acyl-CoA-binding proteins help plants “degrease” adversities
Serving as the building blocks for triacylglycerides and membrane phospholipids, fatty acids are essential in all forms of life. Given their chemical inertness, fatty acids need activation into a more water-soluble form (as acyl-CoA esters), prior to
Long-term outcomes of robotic pyeloplasty for ureteropelvic junction obstruction
Ureteropelvic junction obstruction occurs in both adults and children when the ureter (the tube that carries urine from the kidney to the bladder) becomes blocked, preventing the flow of urine out of the kidney. Surgery is often
The search for new drug candidates to treat Chagas disease
Chagas disease (CD) is a parasite-born pathology caused by a unicellular microorganism called Trypanosoma cruzi. This illness causes a significant morbidity and mortality in the developing world, being endemic in 21 countries across Latin America, representing also
How cancer begins and how to prevent it
Cancer is a problem of chemical carcinogenesis. This means that chemicals are involved in the processes leading to cancer. Knowledge of how certain molecules work is, therefore, essential for understanding how cancer begins. The chemicals that cause
It’s time to leave the wilderness
Child Neurologists are the specialists who take care of children with diseases of the brain, spinal cord, nerves, and muscles. Some of those conditions include epilepsy, migraine, cerebral palsy, muscular dystrophy, and autism. Child Neurology was recognized
Dining at extraordinary locations: new species of bacteria on fatty diet
Birds are among the most popular organisms on earth. Their majestic appearance, lovely songs as well as the ability to fly have always thrilled people making them one of the most thoroughly investigated classes of the animal
A new test to select more effective treatments for lung cancer
Sadly, the majority of patients with Lung Cancers who cannot be treated by surgery to remove their tumour, die within a few years. Small numbers are beginning to benefit from chemotherapies which target very specific types of
Erythrocytes, not leukocytes, clear bacteria from blood circulation
After discovery of phagocytosis by Elie Metchnikoff in 1882, it has become an axiom that in human body white blood cells (leukocytes) are the main cells that engulf and destroy bacteria and other pathogens. But until recently, there has
Body weight and age may predict severity of obstructive sleep apnea in children
Obstructive sleep apnea (OSA) in children is a common clinical problem that causes obstruction to breathing during sleep. Affecting one in ten children, the growing prevalence of this problem has attracted national attention. The hallmark of OSA
Less is more for staging vaginal cancer
Criteria for predicting the survival of women with vaginal cancer has been established by physician specialists trained in treating gynecologic cancers in the United States and around the world. The current 5-year overall survival is approximately 74%
The relationship between clinical and standardised tests for hand-arm vibration syndrome
Hand-arm vibration syndrome (HAVS), previously known as vibration white finger, may be difficult to diagnose. It manifests in two forms – vascular with blanching of the fingers or sensorineural with tingling, numbness and loss of dexterity of
The management of horses during fireworks in New Zealand
The negative effects of fireworks on companion animals have been reported, but little has been documented on the impact on horses. Horse anxiety was commonly associated with fireworks, and 26% of owners reported horses injuries as a

Association between periodontal disease and erectile dysfunction
Chronic periodontitis is a common inflammatory condition of infectious origin that affects the supporting periodontal tissues (including cementum, gingiva, periodontal ligament and alveolar bone) resulting in bone loss and, if left untreated, in tooth loss. In the
Are the physicochemical properties and bacteriological composition of composts linked?
Compost is the product of composting, which is a biological process to valorize and recycle a variety of organic wastes. Given the benefits of composting numerous industrial units have been commercializing this type of product. The parameters
