Abstract
The animal model deals with the species other than the human, as it can imitate the disease progression, its’ diagnosis as well as a treatment similar to human. Discovery of a drug and/or component, equipment, their toxicological studies, dose, side effects are in vivo studied for future use in humans considering its’ ethical issues. Here lies the importance of the animal model for its enormous use in biomedical research. Animal models have many facets that mimic various disease conditions in humans like systemic autoimmune diseases, rheumatoid arthritis, epilepsy, Alzheimer’s disease, cardiovascular diseases, Atherosclerosis, diabetes, etc., and many more. Besides, the model has tremendous importance in drug development, development of medical devices, tissue engineering, wound healing, and bone and cartilage regeneration studies, as a model in vascular surgeries as well as the model for vertebral disc regeneration surgery. Though, all the models have some advantages as well as challenges, but, present review has emphasized the importance of various small and large animal models in pharmaceutical drug development, transgenic animal models, models for medical device developments, studies for various human diseases, bone and cartilage regeneration model, diabetic and burn wound model as well as surgical models like vascular surgeries and surgeries for intervertebral disc degeneration considering all the ethical issues of that specific animal model. Despite, the process of using the animal model has facilitated researchers to carry out the researches that would have been impossible to accomplish in human considering the ethical prohibitions.

Abstract
Antibody-mediated rejection (AMR) has emerged as a major cause of renal allograft dysfunction. C4d, a specific marker for AMR diagnosis, was strongly recommended for routine surveillance; however, currently, C4d detection is dependent upon tissue biopsy, which is invasive and provides only local semi-quantitative data. Targeted ultrasound imaging has been used extensively for noninvasive and real-time molecular detection with advantages of high specificity and sensitivity. In this study, we designed C4d-targeted microbubbles (MBC4d ) using a streptavidin-biotin conjugated method and detected C4d deposition in vivo in a rat model of AMR by enhanced ultrasound imaging. This noninvasive procedure allowed successful acquisition of the first qualitative image of C4d deposition in a wide renal allograft section, which reflected real-time C4d distribution in grafts. Moreover, we introduced normal intensity difference for quantitative analysis, which exhibited a nearly linear correlation with the grade of C4d deposition according to pathologic analysis. In addition, this approach showed no influence on survival rates and pathologic features in the microbubble injection groups, thereby demonstrating its safety. These findings demonstrated a simple, noninvasive, quantitative, and safe evaluation method for C4d, with the utility of this approach potentially preventing patients from having to undergo an invasive biopsy.

Abstract
In the past few decades, cardiac ultrasound has become a widely available, easy-to-use diagnostic tool in many scenarios in acute cardiac care. The introduction of microbubbles extended its diagnostic value. Not long thereafter, several investigators explored the therapeutic potential of contrast ultrasound on thrombus dissolution. Despite large improvements in therapeutic options, acute ST elevation myocardial infarction remains one of the main causes of mortality and morbidity in the western world. The therapeutic effect of contrast ultrasound on thrombus dissolution might prove to be a new, effective treatment strategy in this group of patients. With the recent publication of human studies scrutinising the therapeutic options of ultrasound and microbubbles in ST elevation myocardial infarction, we have entered a new stage in this area of research. This therapeutic effect is based on biochemical effects both at macrovascular and microvascular levels, of which the exact working mechanisms remain to be elucidated in full. This review will give an up-to-date summary of our current knowledge of the therapeutic effects of contrast ultrasound and its potential application in the field of ST elevation myocardial infarction, along with its future developments.

Abstract
Inspired by theranostic technologies, we electrostatically loaded proteinaceous microbubbles (MBs) with a model drug, doxorubicin (Dox) to couple their utilizations in diagnostic imaging with drug loading. A temperature-sensitive polymer, poly(N-isopropylacrylamide-block-acrylic acid) (poly(NIPAM-b-AAc)) was used to encapsulate the Dox-loaded MBs to prevent premature release and to control the Dox release thermally. An LCST of 39°C, slightly higher than normal body temperatures, enables the release of Dox through a conformational change of the polymer shell upon moderate heating. The successive loadings of Dox and poly(NIPAM-b-AAc) were confirmed by fluorescent confocal laser scanning microscope (CLSM) imaging, zeta potential measurement, Fourier transform infrared spectroscopy (FTIR), and quartz crystal microbalance with dissipation (QCM-D). Without a polymer shell, Dox-loaded MBs showed a poor in vitro retention of Dox at room temperature, releasing ∼75% within 8h, whereas the polymer-shelled, Dox-loaded MBs did not show any premature release of Dox. From 37°C to 39°C, the cumulative release of Dox from the polymer-encapsulated MBs was increased from ∼20 to ∼90% over a period of 18h based on in vitro release testing (IVRT). However, the release profiles of Dox from the shell-free, Dox-loaded MBs did not exhibit any similar temperature-controlled behavior, releasing ∼90% of Dox within 5h at both 37°C and 39°C.

Abstract
Time and space controlled drug delivery still remains a huge challenge in medicine. A novel approach that could offer a solution is ultrasound guided drug delivery. “Ultrasonic drug delivery” is often based on the use of small gas bubbles (so-called microbubbles) that oscillate and cavitate upon exposure to ultrasound waves. Some microbubbles are FDA approved contrast agents for ultrasound imaging and are nowadays widely investigated as promising drug carriers. Indeed, it has been observed that upon exposure to ultrasound waves, microbubbles may (a) release the encapsulated drugs and (b) simultaneously change the structure of the cell membranes in contact with the microbubbles which may facilitate drug entrance into cells. This review aims to highlight (a) major factors known so far which affect ultrasonic drug delivery (like the structure of the microbubbles, acoustic settings, etc.) and (b) summarizes the recent preclinical progress in this field together with a number of promising new concepts and applications.

Abstract
Cardiac imaging continues to reveal new anatomical and functional insights into heart disease. In echocardiography, both transesophageal and transthoracic three-dimensional imaging have been fully developed and optimized, and the value of the techniques that have increased our understanding of cardiac mechanics and ventricular function is well established. At the same time, the healthcare industry has released new devices onto the market which, although they are easier to use, have limitations that restrict their use for routine assessment. Tomography's diagnostic and prognostic value in coronary artery disease continues to increase while radiation exposure becomes progressively lower. With cardiac magnetic resonance imaging, myocardial injury and recovery in ischemic heart disease and following acute coronary syndrome can be monitored in exquisite detail. The emergence of new combined tomographic and gamma camera techniques, exclusively developed for nuclear cardiology, have improved the quality of investigations and reduced radiation exposure. The hybrid or fusion images produced by combining different techniques, such as nuclear cardiology techniques and tomography, promise an exciting future.
