Exercise echo: a diastolic and systolic function evaluation test for patients with dyspnea
Exercise echocardiography may be of interest for the assessment of patients with dyspnea. Dyspnea on effort may be an angina-like symptom, and in this case ischemia should be ruled out, or reflect diastolic dysfunction, and in this
Impulsivity and FFFS traits relate to resting frontal activity: Influence of experimenter’s gender
Gray’s revised reinforcement sensitivity theory (rRST) of personality postulates three main systems: the behavioral approach system (BAS), the fight-flight-freeze system (FFFS) and the behavioral inhibition system (BIS) which govern the two motivational systems. This theory has attracted
Carbon monoxide levels after use of heated tobacco products
Heated tobacco products (HTPs) are new tech devices that release nicotine and other volatile compounds into an inhalable aerosol by heating the tobacco. At their operating temperatures, tobacco combustion is unlikely. The aim of this randomized cross-over
Most common behavioral problems in people with dementia
With people all over the world living longer, more and more of them develop problems with brain functions. Some of these problems are mild, e.g. slight forgetfulness, but some may interfere with their daily activities, such as
How alcohol consumption might contribute to viral liver infections?
The coexistence between excessive alcohol consumption and hepatitis C virus (HCV) infection is causative of a high death ratio annually. It is well-known that phosphoinositides (PI) not only regulate a number of physiological processes but also they
Tumor regression in a high-mortality mouse pancreatic cancer (xenograft) model with aminosteroid RM-581
Pancreatic cancer is classified as a high-mortality cancer with a five-year relative survival rate of only 9%. Although most cancer type survival rates have improved over the past decades, pancreatic cancer morbidity has been stable, which illustrates
64Cu and 67Cu radionuclide to diagnose and treat of cancer: Experimental and theoretical Production yields
As the number of patients suffering from different cancers has been increased, researchers have evaluated several ways to diagnose and treat these abnormalities. In this regard, application of radionuclides is an interesting option through which some cancers
Bell ringers: Concussion problems in youth football players
Concussion has become an important topic in sports news and research. While researchers are studying the mental, physical, and emotional effects of concussion within professional, college, and high school athletes; the negative effects of concussion on youth
Health care utilization for chronic musculoskeletal pain risk: Lessons from the CRASH study
Each year, over four million people go to U.S. Emergency Departments (ED) after a motor vehicle crash (MVC). Although the vast majority of patients are sent home without any serious injuries, many will experience aches and pains
Thyroid hormone ratio and clinical outcome: results from the Toreador Study
From a physiopathological point of view patients with advanced solid cancer and neoplastic cachexia might be associated, in some way, with frail older patients, a well-known and extensively described multi-factorial clinical condition, characterized by increased catabolism and
Climatic connectivity may drive bird migration strategies
To maximize fitness, migratory organisms must choose the best place and time to perform their fundamental activities in the face of unpredictable variation in ecological conditions. Because natural selection strongly penalizes the individuals that fail to synchronize
An integrated genomics approach for identifying breast cancer patients with highly aggressive tumors
Breast cancer is the most common cancer in women with over 2 million new cases worldwide in 2018. Three kinds of receptors are usually found on the surface of breast cancer cells: a receptor for female hormone
Can nanographene cross placental barrier?
Graphene is an upcoming revolutionized 2D material that has sketched its importance across a wide spectra of interdisciplinary arenas due to its distinguishing properties. Being a sp2 hybridized allotrope of carbon with a honeycomb lattice structure; it
What’s the point? Cognitive advantage
Neuroscientists have long wondered why some behaviours are mostly controlled by one side of the brain. This phenomenon is called brain lateralization. For centuries we have known that damage to the left but not the right side
The healthy neighborhoods healthy families initiative: A zip code should not determine a child’s health
Published in the journal Pediatrics, researchers from Nationwide Children’s Hospital presented a case study for treating a neighborhood as a patient. Neighborhood effect syndrome, characterized by symptoms of extreme poverty including housing insecurity, racial segregation, trauma, violence,
The difference of an amide to ester in polymers does the magic
Antibiotics kill bacteria by a specific targeting mechanism, and thereby, bacteria quickly develop resistance to antibiotics. The bacterial cell membrane is pivotal to its survival and is considered its Achille’s heel. Killing bacteria by attacking their cell
Why are processed vegetable foodstuffs not as green as raw? Following the fate of chlorophylls
In addition to play an important role in photosynthesis and plant physiology, chlorophylls fulfil certain biological activities. Chlorophylls and their derivatives have been shown to exert antimutagenic and anticarcinogenic activity. In the human diet, these compounds are
Wicherhamomyces anomalus biofilm supported on wood husk for chromium wastewater treatment
Toxic heavy metals are harmful pollutants increasingly discharged in the environment by natural and anthropogenic means. Due to its widespread use in industrial processes, chromium presents a significant impact on the surface waters and ecosystem services. Because
Heart medication and metabolism: What physicians should reflect on to keep them in harmony
Cardiovascular diseases are the leading cause of death globally and have been for a long time. This spotlight has ensured that doctors treating patients with heart problems have a wide variety of medications to work with. Most
Chronic Care Model and multi-morbidity patients. Insights from patients’ perception
More and more countries have been implementing chronic care programs, such as the Chronic Care Model (CCM) to manage non-acute conditions of diseases in a more effective and less expensive way. Among the CCM components there are
