Routine imaging in patients with follicular lymphoma in remission
B-cell lymphomas are a heterogeneous group of malignancies originating from B lymphocytes. Modern day chemotherapy is effective in inducing disease remission in a large percentage of patients for most of the subtypes. Some of these subtypes, the
Authentication of Egyptian blossom honeys
Twenty-two blossom honey samples (clover and citrus honeys) were collected from the greater Cairo area during harvesting year 2014-2015. The main purpose of the present study was to characterize the aforementioned honey types and to investigate whether
Functional significance of interhelical interactions between aspartic acid and cysteine residues in microbial rhodopsin
Microbial rhodopsins are photoreceptive seven-transmembrane proteins that contain all-trans retinal as a chromophore. Upon photon absorption, these proteins undergo a cycling photoreaction, where first the initial trans-to-cis isomerization of retinal induced by illumination leads to the formation
Treatment of experimental eye inflammation with a single subconjunctival injection of liposomal steroid
Non-infectious anterior uveitis is an inflammatory condition in the front of the eye that can potentially lead to blindness. The current gold standard for treatment is with steroid eyedrops. However, this treatment has several disadvantages. Very little
How to successfully write a scientific essay
Posted by Cody Rhodes If you are undertaking a course which relates to science, you are more or less apt to write an essay on science. You need to know how to write a science essay irrespective
How does homework affect students?
Posted by Kenny Gill Homework is essential in the learning process of all students. It benefits them in managing time, being organized, and thinking beyond the classroom work. When students develop good habits towards homework, they enjoy
Simplified molecular diagnostics on a chip for point-of-care diagnostics
Analysis of blood, urine, and saliva often serves as the primary basis of diagnosis and treatment. Clinical specimens contain signature molecules (‘markers’) such as proteins and nucleic acids that are indicators of infection, cancer, and other diseases,
Do patients return to sport activities after total hip replacement?
Total hip replacement (THR) is a successful procedure to treat end-stage hip osteoarthritis. The procedure is increasingly performed in adults of working age, who often wish to return to highly demanding activities, including a return to sports
Reactive oxygen species, Devil or Angel?
Reactive oxygen species (ROS) have an amazing oxidative potential with oxidative stress and could abolish the integrity of living cells. Vigorous production of ROS can damage mitochondria and DNA, which would persistently destroy the cells and might
How cancer cells communicate with nervous and immune systems
In the last decade, studies have shown that cancer cells can influence their environment and bi-directionally communicate with other systems including immune and nervous systems. The neuro-immune interaction is a key player in influencing cancer development and
Using a uniform definition for growth restricted fetuses
Once a woman gets pregnant, the fetus develops and grows through exchange of oxygen and nutrients between the mother and fetus in the placenta. Each fetus has its own growth potential. Therefore, some fetuses are smaller than
Can “low calorie”-oil enhance the secretion of incretin hormones with beneficial effects on diabetic patients?
When the human body digests dietary fat (triacylglycerol), hormones from the intestine called incretins are released from the small intestine. These hormones stimulate insulin release and inhibit food intake. The mechanism for the fat-induced incretin release involves
Nanotechnology, is it something useful for future agriculture?
Nanotechnology has been applied in various fields – biomedicine, electronic devices, renewable energy optical electronic medicine, physics, pharmaceutics. Does it have a place in agriculture? It is generally accepted that manipulation of a crop’s native microbiome represents
Can the heart get cancer? Quite rare, but yes
To many, the heart seems as an unusual location for cancer. In fact, most tumors that affect the heart are metastatic in origin (start in other organs and disseminate to the heart). Primary cardiac tumors (tumors that
Hearing the light: Improved frequency resolution of optical vs. electrical inner ear stimulation
Auditory signals, including human speech, are characterized by many features, one important being sound frequency, which is perceived as pitch. In normal hearing people, the cochlea in the inner ear translates different sound frequencies into neural activation
How well can serum miRNAs diagnose amyotrophic lateral sclerosis patients?
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease that damages motor neurons. As the disease progresses, patients gradually loose exercise capacity. Finally, they die due to the lack of breathability. No effective therapy was found for ALS
