Ketones usually simple are compounds that contain a carbonyl group, and due to exclusion of reactive groups such as –Cl or –OH, ketones are considered simple in nature. Industrial solvent acetone and sugar (ketoses) are some of the commonly used ketones. Various methods are implemented for the production of ketones in academic laboratories on an industrial scale, and are also produced in certain ways by organisms. Ketones are manufactured in industries on a large scale as pharmaceuticals, polymer precursors and solvents. On the basis of their type, ketones are divided into cyclohexane, methyl ethyl ketone (MEK) and acetone. Ketones are a common term in biochemistry, however, a lesser known term in organic chemistry. MEK is a colorless, flammable, stable liquid with similar odor to acetone. MEK exhibits the ability to be miscible with water and other organic solvents. MEK is a valuable and powerful solvent for many solvents such as resinous materials owing to its exceptional solvency.

Toxicity is an extent to which a particular substance can damage the living organism; it is important parameter to be evaluated during all stages of drug development. Toxicity is one of the major reasons for failure of drug development and rejection of drug candidate. Toxicity can be because of dosage, form, half life and other parameters of drug. Since long time toxicity is measured at the later stage of the drug development process but considering higher rejection rate of drug in recent years citing high toxicity level and cost impact of later stage failure, companies started early toxicity testing and taken measures accordingly to reduce the attrition rate in drug discovery.

Tar is produced from a variety of natural materials through destructive distillation. Tar can be extracted from petroleum, coal, peat and wood. Tar is a mixture of free carbons and hydrocarbons. Products bearing a resemblance to tar can be extracted from hydrocarbons. Coal tar is produced during the process of coke production as a byproduct from coal. Tar is generally used in carbon black and deep processing. Tar sand deposits contain mixtures of heavy crude and mixture of sand.

Bio-imaging refers to tools and technologies used to create structural or functional images of living objects or systems. Medical imaging in bio-imaging involves use of techniques and processes to create images of the anatomical areas and tissues of the human body to the molecular level. This helps in diagnosis and examination of disease and also helps to establish database of normal anatomy and physiology for future study. On the other hand, molecular biology in bio-imaging is related to the spatial and temporal arrangement of biological macromolecules. Bio-imaging incorporates radiology which involves various imaging technologies of X-ray radiography, medical ultrasonography or ultrasound, magnetic resonance imaging, elastography, endoscopy, thermography, tactile imaging, medical photography and nuclear medicine functional imaging techniques such as positron emission tomography. Medical imaging is considered as a set of techniques that produce images of internal structures of the body non-invasively. Bio-imaging aims to improve human health with the use of imaging techniques to advance diagnosis, prevention and treatment of human diseases.

Trimethylopropane (TMP), is an organic compound which contains three hydroxyl functional groups. It is a white crystal in its solid state and when melted it is a transparent liquid. TMP is a hygroscopic compound and should be stored carefully in order to avoid moisture absorption. This compound is readily soluble in water, alcohol and in acetone. It is a very stable compound and does not cause any specific danger to the environment. TMP is usually manufactured in the form of semi transparent white flake and when melted forms a transparent melted liquid.

Dental laboratories perform technical procedures related to dental treatment without any direct involvement of the dentists and patients. These laboratories manufacture and customize variety of dental products like dentures, bridges, crowns and others. Dental laboratories comprises of various dental technicians like laboratory technicians, dental technologist, dental ceramics and others. These laboratories have strategic contracts with patients and many pharmaceutical and other industries that purchase their dental materials.

Natural fatty acids and their various derivatives are predominantly used in a wide range of industries such as personal and household care, plastics, rubber and detergents among others. Stearic acid, fractionated fatty acids, distilled fatty acids, polyunsaturated acids such as tall oil fatty acids and oleic acids are various types of natural fatty acids used across the globe. Raw materials such as palm, palm kernel oils and coconut are used in the production of natural fatty acids. The growing demand for natural fatty acids from the end-user industries such as personal and household care, plastics, rubber and detergents across the globe is predicted to drive the global natural fatty acids market in the years to come.

Bone morphogenetic proteins are multifunctional growth factors and are expressed during the cartilage repair, early fracture, and limb development. Currently, around 20 different BMPs are identified, where each protein possesses different degrees of tissue stimulating properties. These proteins provide means for quick recovery from fracture, where bone healing or augmentation is required. These proteins have been especially helpful in spinal fusion. BMPs are more likely to be used in patients who have undergone previous surgery or patients who are undergoing complex spinal fusion procedures.

Vertebral compression fracture (VCF), a spinal disorder is caused due to the compression of vertebrae because of trauma, osteoporosis, primary tumors or infections; resulting in spinal deformity, disability, and acute or chronic pain. Such fractures may be mild or severe in nature and most often occur in the thoracic and lumbar parts of the spinal cord. The non-surgical procedures for treating pain caused in VCF include bed rest, pain medication, back bracing, and physiotherapy. Modern VCF treatment options such as minimally invasive surgical procedures which involve injecting of cementing material in the fractured vertebra provide immediate relief from pain and stability to the patient. Post surgery complications may include failure of the bones to fuse, humpback and compression of spinal cord or nerve root.

Effective closure of surgical incisions plays a crucial role in post-surgical process to regain normal anatomical functions and maintain the integrity of tissues. Thus, the primary objective of surgical incision closure devices is to stop bleeding i.e. hemostasis and to close or seal the wound both externally and internally. Failure to close surgical incisions effectively can lead to severe medical complications such as infection and scarring. The commonly involved technique in conventional surgical incision closure is the use of surgical sutures for stitching together the incised skin edges. But modern methods introduced are more advanced and convenient; to mention some of the advanced methods - use of adhesives, hemostats, medical staples and sealants.
