The amount of impaction and loss of reduction in osteoporotic proximal humeral fractures after surgery
More than 90% of proximal humerus fractures affect the elderly. Thus, we should understand that these are osteoporotic fractures. We can imagine the proximal humerus of the elderly as an egg shell, a broken egg shell. Fixation
Delaying surgery for IBD patients may have grave consequences
When discussing a proposed therapy for any illness, patients undoubtedly, and understandably, want to know the side effects. This includes the most serious side effect – the risk of death. The Inflammatory Bowel Diseases (IBD), comprised of
A electrochemical biosensor for the detection of antibodies against avian influenza virus type H5N1 in hen sera
Avian influenza (AI) is a highly contagious disease caused by Orthomyxoviridae family viruses. Highly pathogenic avian influenza (HPAI) virus can be easily transmitted between poultry, leading to severe disease outbreaks or even pandemics. It is difficult to
A novel micro-injector for micro injection in dental application
Micro-injection technology is widely used in clinical surgery. Herein, periodontal disease is to be a starting point, we will develop a novel micro-injector carrying bone graft substitutes for repairing bone defect to minimizing the patient’s discomfort. Periodontal
Predictors of 360-day survival in centenarians
Healthy aging assumes the combination of longevity and quality of life. Quality of life in old age is associated with mental and physical well-being allowing for independent living and social function. Appropriate scales can be used to
Can Beautyberry treatment improve the success rate of lung transplantation?
Ischemia/reperfusion injury is a type of organ damage that occurs when blood supply returns to the organ after a period of ischemia and a direct consequence of oxidative stress. It significantly contributes to the risk of mortality
Osmoregulation in phytopathogenic fungi
Osmosis is a phenomenon in which water moves always from higher to lower chemical potential, commonly towards the area with higher solute concentration. Living cells are semi-closed systems with membranes permeable for water but not for many
Rat model of small opaque eyes open the door to eye research
Ocular diseases in elderly persons, such as cataract and age-related macular degeneration (AMD), one of the main causes of vision loss in developed nations, are paid great attention nowadays. The eye is a complicated organ constructed with
Modulation of immunity and gut microbiota
Animal bodies have many bacterial cells and a large part of them live in our digestive system. The relationship of gut bacteria to many aspects of wellness and health including immunity it is known. Regrettably, the current diet is
Exploring the amazing capacity of many bacteria to swim towards specific chemicals
Many bacteria possess flagella, which are flexible filaments attached to the bacterial surface. These filaments can rotate which in turn propels the bacterium forward and enables them to swim. However, this swimming behavior does not simply occur
Cancer risk in opposite-sex and same-sex twins
Twin pregnancies are characterized by simultaneous development of two fetuses that share the womb. An interest in opposite-sex (OS) twins, twin pairs consisting of one male and one female, comes from animal studies that showed that exposure
A promising biointerface for endothelial cells assembled from mixed poly(dopamine) film
When implants are put into a patient’s body, there will be contact between this material and the surrounding tissue. Successful implantation requires that the body integrates the foreign materials. The surface of implants plays an important role
Can mathematics help defeating acquired blindness?
Sight threatening pathologies of the eye retina, the light sensitive tissue lining the back of the eye, are an increasing health concern in the ageing population. A number of risk factors, including high intraocular pressure, high blood
Image processing as a facile method to determine pore size distribution in porous scaffold
Scaffold for tissue engineering are porous devices which allows the regeneration of living tissues such as bone, cartilage or other tissues. Some studies demonstrated that the regenerative properties of the scaffold are strongly dependent both on the
Operationally simple reactions with unprotected carbohydrates – an application of organocatalysis
Carbohydrates are ubiquitous in nature. They play an important role as an energy reservoir as well as they are the resource of countless biomaterials, such as cellulose or chitin. This importance has challenged chemists at all times
How does bladder chemotherapy given before surgery change bladder cancer cells?
It is estimated that there will be 74,000 new cases of bladder cancer diagnosed in the United States and approximately 16,000 deaths due to bladder cancer in 2015 alone, according to statistics from the American Cancer Society.
Hong Kong as a hotspot of microplastic pollution
Small plastic debris, known as microplastics, is an emerging global environmental issue affecting different water environments, in particular, the oceans. Most scientists classify microplastics as plastic debris with a particle diameter of less than 5 mm. They
Transplanted cells reveal potential for functional neural regeneration
Patients suffering from spinal cord injury and from neurodegenerative disorders such as Parkinson’s disease, amyotrophic lateral sclerosis (Lou Gehrig’s disease) and multiple sclerosis have high hopes for cell transplantation therapy. Successful transplantation depends on the donor cells
Conditional mutations in drosophila
In 1865, Gregor Mendel discovered the laws of inheritance for the traits of living organisms. Reproduction, the major property of living matter and mode of its existence in the Universe, found itself in the spotlight of biology.
New role of microbes in the construction industry
Such well-established areas of Biotechnology as Medical, Agricultural, and Environmental Biotechnology have thousands of valuable applications but Construction Biotechnology, which is science and engineering of using of microorganisms in construction industry, is just arising. Before that, microbes
