Bulk nanocomposites prepared from aqueous albumin dispersion with carbon nanotubes by removing the liquid component from the dispersion have been investigated. The composites were obtained by thermostating and exposure to LED and IR diode laser radiation. The nanocomposites obtained under laser irradiation retain their shape and properties for several years, in contrast to the composites fabricated in different ways (which decompose into small fragments immediately after preparation). The low density of the composites under study (~1200 kg/m3), which is close to the density of water, is due to their high porosity. The hardness of stable nanocomposites (~300 MPa) was found to be at the same level as the hardness of polymethylmethacrylate, aluminium, and iron and close to the hardness of human bone tissue. The cluster quasi ordering of the inner structure of nanocomposites revealed by atomic force microscopy indicates the possibility of forming a bulk nanotube framework in them, which can be caused by the effect of the electric field of laser radiation and ensure their stability and hardness....

Osteoporosis is a debilitating disease that affects many older people. Characterized by low bone mass and microarchitectural deterioration (MAD) of bone tissue, Fragility fractures are the hallmark of osteoporosis. There are potentially numerous nutrients and a dietry component that can influence bone health. Bone mineral consists of calcium phosphate, and phosphorus is as important as calcium in supporting bone augmentation and maintenance. Although typical adult diets contain abundant phosphorus, 10% to 15% of older women have intakes of less than 70% of the recommended daily allowance. Patients at the highest risk for fractures benefit from many approved treatments which can be given orally {alendronic acid, risedronatesodium, zolendronic acid, denosumab, raloxifene, hormone replacement theory (HRT)} which results in increased bone mineral density and reduction of fracture risk. This article initially overviews osteoporosis, including its definition, etiology, and incidence, and then provides some information on possible dietry strategies for optimizing bone health and preventing osteoporosis. The potential benefits of calcium, Vitamin D, Vitamin K, phosphorous and Vitamin C are briefly discussed, along with the different...

Neem has become valuable plant in the world which shows the solutions for hundreds to thousands problems. Neem has become important in the global context today because it offers answers to the major concerns facing mankind. Neem has been extensively used in Ayurveda, Unani and Homoeopathic medicine and has become a centre of attraction of modern medicine. Azadirachta indica (neem) is a rapidly growing evergreen well known tree found generally in various regions of world like America, Africa and India. The aim of this review article provides information mainly on various pharmacological activities like anti-inflammatory, antimalarial, anti-bacterial, anti-allergic, antidermatic, antiulcer, antifungal, insecticidal, larvicidal and other pharmacological activities of neem plant and medicinal...

Science and technology have greatly contributed to man’s never-ending quest for quality improvement in different domains of life. But in the process of development, the usage of radiation-based technologies has considerably increased in the fields of medicine, agriculture, aviation, space, warfare, food processing, electronic and communication systems, nuclear-power generation and other industrial activities. These anthropogenic activities, in addition to natural processes, have more and more exposed humans knowingly or unknowingly to different kinds of radiations resulting in morbidity or mortality. In view of the high costs and side effects of the currently available radioprotective drugs, research continues to explore safe and effective radioprotectants preferably natural product-based ones. In the Traditional Indian and Chinese systems of medicine, several plant species have been reported to possess great medicinal values to treat various ailments. This article reviews and updates the promising plants and herbs, their extracts / bioactive principles and their mode of action as radio-protectants. Systematic and scientific studies pave the way to develop efficient drugs/formulations to protect or prevent from...

Diabetes is one of the deadliest and non-contagious diseases that can adversely affect several parts of human body. Early prognosis of diabetes can inkling the grievous complications and help to save human life. Several researchers have used different data mining (Iterative Dichotomiser 3, Random Forest, Support Vector Machine, k-Nearest Neighbour, C4.5) and soft computing (Genetic Algorithm, Ant Colony Optimization, Particle Swarm optimization, Artificial Bee Colony) techniques to prospect diabetes in human beings. In last 10 years, C4.5 was the most preferred choice for mining diabetic patients. Likewise, in soft computing, maximum number of researchers have used genetic algorithm. Furthermore, the usage of pre-processing techniques is significantly increasing in diabetes diagnosis. It is also observed that rate of accuracy achieved in diagnosing diabetes using traditional data mining lies in 68.5% – 95.3%. Likewise, the range for soft computing and their hybridized use lies in 74% – 100%. In addition, rate of accuracy achieved using GA based hybridized approach is better than the accuracy obtained using PSO as well as ABC....
