Abstract New copolymeric membranes was offered for the efficient delivery of antibiotic drug using the synthesized chitosan–copoly(semicarbazide–formaldehyde–phenylhydrazine) blend membranes. The membranes were prepared by solution casting technique and characterized by elemental, spectral and scanning electron microscopy to establish the chemical structure and morphology. Scanning electron microscopy clearly reveals that the increased porosity in the polymeric network enables rapid swelling; leads to faster diffusion which facilitates effective drug release. The composition of chitosan content also governs the swelling behavior i.e. increased chitosan content showed excellent swelling behavior leads to profound drug delivery.
Tissue engineering and regenerative medicine are an interdisciplinary field that aims to maintain, repair or improve tissue functions that are defective or lost by Disease, injury and trauma, either by developing biological substitutes or by reconstructing tissues. Tissue autografting and allografting are commonly approaches that have used for replacing damaged or diseased tissue. Nevertheless, these approaches have faced with several drawbacks. Tissue engineering involves three key factors: scaffold, signaling molecules and cell culture. The development of scaffolds are the main areas of biomaterials research, and they play a pivotal role in tissue regeneration and repair.
PEMFs have well-documented physiological effects, including increasing levels of glycosaminoglycan. • Finally look at stem-cell therapy. In this increasingly popular procedure, a patient’s stem cells are extracted, cultured and then reinjected into the damaged knee. Dr Chris Centeno of the Centeno Schultz Clinic, Colorado, US, which pioneered the procedure, advises to opt for a procedure that uses mesenchymal stem cells (MSCs). They are considered superior because they are already partially committed to becoming bone, muscle, ligament or tendon, they are also easily harvested from bone marrow and reproduce rapidly.
Therefore the topic of cell membranes has been extensively researched, meaning that there is no limit to information and sources of information of the subject. The effects of alcohols on membrane have also been researched quite extensively. Previous studies have found that alcohols disrupt the structure of cell membranes (Goldstein, 1986). They have also found that ethanol has a stronger effect than other alcohols (Patra et al, 2005). From this research and literature the expected results of the experiment were to see an increase in membrane permeability, this result was observed.
As seen here, membranes consist of a phospholipid bilayer with specific proteins embedded in the bilayer. The bilayer is made up of phosphate heads and lipid tails. The heads are hydrophilic whereas the tails are hydrophobic. The amphipathic nature of the phospholipid molecules greatly assists the cell membrane in it’s selectively permeability. It helps the cell to transfer many molecules through the membrane.
Results: There is a significant increase in LDH (p<0.005) levels in OSCC patients when compared with healthy controls, by the influence of OSCC on LDH metabolism. Conclusion: Our findings suggest that assessment of LDH can be used an effective biochemical diagnostic tool for the manifestation of OSCC and other type of malignancy in patients. Key words: OSCC, cell damage, carcinoma, oral cavity, lipid profile status.
Hypodermal fat act as heat insulator in body. Highly vascular drugs such as insulin is administered this layer because it is highly absorptive. 1.3. Melanin Melanin is present in both epidermal and dermal layer of skin. It is formed in small membrane stacks called melanocytes.
Calcium sulfate (CS) (CaSO4) occupies a unique position among bone regenerative materials. It is used in clinical practice for long time than most currently available biomaterials and is widely recognized as a biocompatible material with applications in bone regeneration. It has the advantage that it is available and inexpensive (Thomas & Puleo, 2009). The ‘‘gypsum’’ or CS is a mineral consisting of calcium sulfate dehydrate (CaSO4.2H2O). It must be screened before use in medical practice for impurities such as silicates, lead, strontium, and other naturally occurring materials (Ricci, Alexander, Nadkarni, Hawkins, Turner, Rosenblum, Brezenoff, De Leonardis & Pecora, 2000).
Increasing functionalities mean that ultrasound single machines can be used for a range of operations that would otherwise require separate devices. An example of such malfunctioned ultrasound devices is the Siemens ACUSON S2000 which supports acoustic radiation force impulse (ARFI) and conventional ultrasounds. ARFI has been hailed as one of the more effective procedures for the diagnosis of “liver fibrosis among a range of other non invasive procedures.” Overall, the ACUSON S2000 ultrasound system provides images of better and can be used to perform delicate procedures ("The Next Wave In Ultrasound
