Medical Retina

The human fundus is a complex structure that can be easily visualized and the world of ophthalmology is going through a golden era of new and exciting fundus imaging techniques; recent advances in technology have allowed a significant improvement in the imaging modalities clinicians have available to formulate a diagnostic and treatment plan for the patient, but there is constant on-going work to improve current technology and create new ideas in order to gather as much information as possible from the human fundus. In this article we shall summarize the imaging techniques available in the standard medical retina clinic (i.e. not limited to the research lab) and delineate the technologies that we believe will have a significant impact on the way clinicians will assess retinal and choroidal pathology in the not too distant future.

Introduction: Brain tumor is among the major causes of morbidity and mortality rates worldwide. According to National Brain Tumor Foundation (NBTS), the death rate has nearly increased by as much as 300% over last couple of decades. Tumors can be categorized as benign (non-cancerous) and malignant (cancerous). The type of the brain tumor significantly depends on various factors like the site of its occurrence, its shape, the age of the subject etc. On the other hand, Computer Aided Detection (CAD) has been improving significantly in recent times. The concept, design and implementation of these systems ascend from fairly simple ones to computationally intense ones. For efficient and effective diagnosis and treatment plans in brain tumor studies, it is imperative that an abnormality is detected at an early stage as it provides a little more time for medical professionals to respond. The early detection of diseases has predominantly been possible because of medical imaging techniques developed from past many decades like CT, MRI, PET, SPECT, FMRI etc. The detection of brain tumors however, has always been a challenging task because of the complex structure of the brain, diverse tumor sizes and locations in the brain. Method: This paper proposes an algorithm that can detect the brain tumors in the presence of the Radio-Frequency (RF) inhomoginiety. The algorithm utilizes the Mid Sagittal Plane as a landmark point across which the asymmetry between the two brain hemispheres is estimated using various intensity and texture based parameters. Result: The results show the efficacy of the proposed method for the detection of the brain tumors with an acceptable detection rate. Conclusion: In this paper, we have calculated three textural features from the two hemispheres of the brain viz: Contrast (CON), Entropy (ENT) and Homogeneity (HOM) and three parameters viz: Root Mean Square Error (RMSE), Correlation Co-efficient (CC), and Integral of Absolute Difference (IAD) from the intensity distribution profiles of the two brain hemispheres to predict any presence of the pathology. First a Mid Sagittal Plane (MSP) is obtained on the Magnetic Resonance Images that virtually divides brain into two bilaterally symmetric hemispheres. The block wise texture asymmetry is estimated for these hemispheres using the above 6 parameters.

Background. The avalanche-like growth of intravitreal injections in the world has significantly increased interest in the hemodynamics of the processes that occur in the eye when a drug is injected into the vitreous cavity. Every year, the number of intravitreally used drugs and promising areas in which they can be used is growing. This also applies to the creation of new combined medicines and the development of drugs with a long-term therapeutic effect. Aims. Create mathematical model of eyeball to evaluate the movement of the drug substance in it; to estimate the time of the drug's presence in the eye cavity before its complete removal, to characterize the ways of its removal from the eye cavity; to assess the significance of posterior vitreous detachment during the time when the drug is present in the eye cavity; to evaluate the effect on the hydrodynamics of the depth of drug administration. Results. When the drug is administered closer to the center of the eyeball, its residence time increases in comparison with the parietal administration. With a complete posterior detachment of the vitreous body, the time of finding the drug in the eye is prolonged compared to its absence. The obtained results of mathematical modeling of the movement of the drug administered intravitreally cannot be mechanically transferred to the human eye, due to the more complex structure of the latter. Key words: intravitreal injections, vitreous body, mathematic computing.

<p class="1Body">Rice is staple in the African habitats menu. Bacterial wilt (BLB) and leaf streak (BLS) are some of the phytopathological diseases which restrain rice production around the world. In this paper, multi-spectral and multi-modal imaging techniques have been developed to characterize the rice leaves with symptoms of bacterial wilt (BLB) and leaf streak (BLS), and to provide information on their effects, in order to reduce their spread. First, we recorded microscopic and spectroscopic images of the samples using multimodal and multispectral microscope, with spectral region ranging from UV to NIR, for each mode. Then, we extracted the spectral footprints of the cells constituents, in transmission, reflection and scattering from the spectral images. Applying multivariate statistical analysis methods to this optical spectra allowed us to characterize the effect of bacterial rice leaves caused by <em>Xanthomonas oryzae</em> strains. The results of the proposed technique can be useful for easy identification of this type of infection, and can serve as routine approach in biochemical and agronomic laboratories.</p>

John Sealy Edward Townsend, one of the great physicists of this century, lived through a period during which the fundamental concepts of natural science underwent a bewildering series of changes. Unlike many of his scientific colleagues, he remained completely undismayed by the storms raging in the world of physics, though he accepted some of the new ideas with due scepticism. It is often noticed that scientists when they approach the end of their active lives turn to other fields of human endeavour such as mysticism, economics or cosmogony. But this certainly did not apply to Townsend, who remained a pure physicist until the end of his life.

Since the 1990s, scholars around the world have focused on the complexities of governance reforms. The vicissitudes of the 21st century witnessed global waves for public administration reforms. China, a fast developing socialist country, has been building a strong, robust and modern public governance system. The Socialist Governance of China with Chinese characteristics brought considerable changes in the political, economic and social spheres, transforming the lives of people for betterment. By bringing about economic development through state intervention, introducing rule of law upholding the significance of its people, fostering new ideas, and ushering the ideology of nationalism through “China Dream”, President Xi Jinping and his socialist governance policies have created an excellent example in the world, particularly the capitalist society, demonstrating how society can be developed through socialist ways. Yet, the dynamics of Chinese governance has always been part science and part mystery to other governments that have earned legitimacy through elections, while China’s leaders earned its legitimacy through selection of the most able and their performance in delivering sustained improvements in the quality of life of the Chinese citizens and China's international standing. This paper deals with assessing the relevance of China’s Socialist governance evolution into a science of managing public affairs and the pursuit to optimizing its impact on the state’s economic, political and social spheres.

?New age? was a trend which appeared in the music of the 1980?s, bringing a new dimension to art music in general, especially in its reception. At first its development was stimulated by technological inventions, ?the technological craze?, by new carriers of sound, simultaneously globalizing art and making it widely accessible. This new trend includes quite disparate categories. It does not distance itself from subculture, and in art music it gravitates towards cosmopolitism while being permeated with other musical trends such as pop, rock, jazz and other phenomena of show business and popular art. This trend was originally found in the large number of occult writing which flooded book markets all over the world, to which Umberto Eco gave an important base (Foucault's Pendulum and others). In his essay on the music of the eighties, Peter Niklas Wilson, one of the most significant theoreticians of this movement, researches into all elements of those novelties, not hesitating to call this art eclectic, commercial and the like. Examples of Serbian music get into such style directives. The New Ideas Symphony by film score composer Zoran Simjanovic, was performed in the open air at Kalemegdan fortress in 2006, before an audience of about one thousand people. Since then the recording has often been broadcast on television and radio channels. In its combination of folklore and film models, traces of rock, pop, and jazz can also be found, in a score with all symphonic characteristics. This attempt is a fascinating item for research as well as a pleasure to be listened to.

Over the past few decades, majority of neurosurgeons only specialize in spinal cord diseases. However, with the advances in spine surgery, more and more neurosurgeons focus on spine diseases. Precision minimally invasive technique in surgery of spine and spinal cord is an important branch of neurosurgery. As traditional surgery has been gradually replaced by precision surgery, open surgery has been gradually replaced by minimally invasive surgery (MIS), the diagnosis and treatment of spine diseases has been benefiting from minimally invasive techniques. With minimal surgical trauma, precise localization, MIS has become the inevitable trend of new neurosurgery. The model of multidisciplinary team is gradually becoming universal in the world in order to make the best treatment plan for the patient with spine diseases on the basis of the comprehensive disciplinary opinion.

Respiratory diseases are top-ranked causes of deaths and disabilities around the world, making new approaches to the treatment necessary. In recent years, lung-on-a-chip platforms have emerged as a potential candidate to replace animal experiments because they can successfully simulate human physiology. In this review, we discuss the main respiratory diseases and their pathophysiology, how to model a lung microenvironment, and how to translate it to clinical applications. Furthermore, we propose a novel alveolus lung-on-a-chip platform, based on all currently available methodologies. This review provides solutions and new ideas to improve the alveolar lung-on-a-chip platform. Finally, we provided evidence that approaches such as 3D printing, organ-a-chip devices and organoids can be used in combination, and some challenges could be overcome.
