Laser in restorative dentistry
The application of lasers in restorative dentistry has revolutionized dental treatments, offering enhanced precision, reduced discomfort, and improved clinical outcomes. Lasers have become a valuable tool in procedures such as cavity preparation, caries removal, tooth whitening, and composite resin curing. Their ability to selectively target diseased tissue while preserving healthy structures minimizes trauma and promotes faster healing. Moreover, lasers offer a less invasive alternative to traditional mechanical methods, often eliminating the need for anesthesia. This technology's versatility allows for its use in both hard and soft tissue treatments, including gingival recontouring and managing peri-implant diseases. As laser technology continues to advance, its integration into restorative dental practices offers significant potential for improved patient care, greater procedural efficiency, and long-term durability of restorations. Future developments in laser applications are expected to expand their role, making them an indispensable asset in modern dentistry.

Lake Victoria : Ecology, Resources, Environment
Recently, there has been, and continues to be, a tremendous interest on Lake Victoria and its environs, both locally and internationally. A casual browsing on the Internet indicates that the entries on the Lake have been rising phenomenally. At the same time, the issues discussed are as diverse as they are varied in their treatment of the subject, both in terms of depth and comprehensiveness. The information on Lake Victoria and its environ is scattered, isolated, and sometimes confusing even though documentation on the subject are available. Despite this situation, the fact remains that various people (e. g. , secondary and universitystudents,researchers,practitioners,etc. ,)wouldliketoaccess and know more about the Lake and its environs. Aware of the existing information gap about this world’s second largest fresh water Lake, this book is intended to provide readers with up-to-date information pertaining the Lake. The book gives an in-depth coverage of environmental issues, - source endowment, poverty amidst plenty, development opportunities, challenges and other related issues facing the Lake and its environs. It aims at providing information on the above variables, which hopefully will address the needs of various users.

La scuola dell’atopia = The school of atopy
The need to clarify the current concepts of atopy, which for too long have oscillated between a primitive purely clinical vision and a subsequent purely immunological one, had been ripe for some time. Understanding that the role of immunoglobulins E is not exhaustive and accepting the Solomonic division between intrinsic and extrinsic atopy were the first two fundamental steps. Recent discoveries of the role of innate immunity, and therefore of antimicrobial peptides, have opened fundamental spaces for understanding in atopy and beyond. What now appears clear is that atopy is not the disease of an organ but rather a defect in the membranes that delimit our "self". The fact that these membranes are called skin, intestines, conjunctiva, bronchi or whatever has artificially fragmented the understanding and treatment of a unitary phenomenon. This book seeks to summarize the different experiences but above all to be a stimulus to ensure that medicine focuses constructively on the same target. If this is the case, we will no longer see "religious wars" between scientists and practicing doctors or, even worse, between the different specialists vying for the patient. If atopy, as we believe, is a global problem, it can only be adequately addressed in a multidisciplinary context and in a collaborative atmosphere, not only between doctor and doctor but also between doctor and patient.
La phytocosmétologie thérapeutique = Herapeutic phytocosmetology
Deals with restorative cosmetology. This is understood through the eyes of the doctor specializing in phytotherapy. Three main aspects are discussed: the diagnosis of disturbance of the skin and integuments, external treatment with natural substances, as well as oral treatment (internal treatment). Oral cosmetology has no official recognition, yet the effects of plant extracts on the condition of the skin and integuments are well known. After an introduction to the physiology of the skin, the dosage and the phenomena of skin deterioration, the author discusses different types of treatment depending on the extracts used while explaining their mode of action. This work was written by a doctor, Doctor Paul Goetz, teacher in clinical phytotherapy, and a pharmacist, Doctor Christian Busser, pharmaceutical and scientific advisor, doctor in ethnology and ethnopharmacologist.
La lombalgie en 2007 : Aspects pratiques = Low back pain in 2007 : Practical aspects
Low back pain is one of the main reasons for consultation, whether in general or specialized medicine. It poses a real public health problem. This "back pain", which can despair patients and doctors by its sometimes rebellious character, explains the multiplicity of examinations sometimes practiced and the treatments implemented. This work is a collection of the most recent developments in terms of physiopathological knowledge of disc involvement, clinical examination and the place of surgery and in particular disc prostheses. An update concerns the indications and contributions of additional examinations; some formidable diagnostic traps are mentioned. Medical treatments such as infiltrations, manipulations, the benefit of restraints and the provision of acupuncture are being developed. Also discussed are the latest scientific data on isokinetic evaluation and retraining, as well as the role of sports activity as a factor in the prevention or aggravation of low back pain. Finally, the medico-legal aspect is dealt with in the context of work accidents, and the assessment after trauma. This book is the result of the collaboration and experience of undisputed specialists in this field.
La gonarthrose : Traitement chirurgical : De l´arthroscopie à la prothèse = Knee osteoarthritis : Surgical treatment : from arthroscopy to prosthesis
The aim of this work is to take stock in a clear and didactic way on all the current knowledge on osteoarthritis of the knee and its treatment. It successively addresses the diagnosis and the medical treatment, then the surgical treatments then finally the various aspects of the total knee prosthesis. This book is designed to be read at several levels: basic information is intended particularly for non-specialist or trainee surgeons, rheumatologists, rehabilitation physicians, radiologists and physiotherapists. More specialized aspects are discussed in a second part of the book concerning the future of medical treatment (biology, gene therapy) and certain complex problems of surgical techniques. The points of controversy concerning the total knee replacement are discussed in the last part of the book, of interest to physicians and surgeons.
La disprassia in età evolutiva : Criteri di valutazione ed intervento = Dyspraxia in developmental age : Evaluation criteria and intervention
As clinical and rehabilitation practice shows, children with dyspraxia are unable to plan and organize an action plan; they cannot control what they are doing during an action; therefore, they cannot do something, but we could also admit that they cannot yet do something; that is, they have not yet learned to perform functions. Functions and actions, however, can be learned and performed with the help of targeted exercises performed consistently. It is, however, essential to recognize the difficulties children with dyspraxia face when faced with new, unusual tasks. The author proposes an assessment and intervention model that takes into account etiological and neuropsychological hypotheses, emphasizing the need to proceed with an analysis on multiple levels: perceptual, motor, and representational. Particular importance is given to early diagnosis and intervention to define and implement appropriate treatment plans. The work concludes with the analysis and description of clinical cases related to some specific forms of dyspraxia: verbal dyspraxia and dysgraphia.
Kristian Birkeland : The First Space Scientist
PREFACEThisscientific biography of Kristian Birkeland (1867–1917) was written to bring the story ofa Norwegian national hero to the attention ofthe English-speaking world. Birkeland’sheroic stature was established not on a field of military battle,but in the bitter cold of the Artic wilderness ashe sought to answer basic questions abouthow the Sun controlled northern lights andmag-netic storms. He was also afather of Norsk Hydro one ofNorway’s largest industries. Birkel and died before reaching the age of 50.Because Birkel and never kept adiary, documented information about his family and private life is sparse. Before he died, Olaf Devik, the last of Birke-ffland’s close friends, gave along interview and graciously transferred his personal archive to A.E. Birkeland’s 82 scientific papers and three book-length publications map the progress of his investigations. addressed this book questions that had vexed European scientists for centuries. Why do the northern lights appear overhead when the Earth’s magnetic field is disturbed? How are magnetic storms connected to disturbances on the Sun? To answer these questions Birkeland interpreted his advance laboratory simulations and daring campaigns in the Arctic wilderness in the light of Maxwell’s newly discovered laws of electricity and magnetism. Birkeland’s ideas were dismissed for decades, only to be vindicated when satellites could fly above the Earth’s atmosphere.
Kratochvil's Fundamentals of Removable Partial Dentures
Provides an overview of the RPD design philosophy developed by Prof F. J. Kratochvil. His'RPI system'—a clasp assembly consisting of a rest, a proximal plate, and an I-bar retainer—changed how clinicians approach partial denture design. Topics in this book include RPD components and functions, design sequences for maxillary and mandibular RPDs, and techniques for surveying and determining the most advantageous treatment position. The authors provide illustrations of clinical cases throughout the book as well as an illustrated glossary of prosthodontic terminology. This book will prepare students and general practitioners to design and fabricate a biomechanically sound RPD framework for just about any dental configuration they encounter.
Knowledge, practices, and awareness of safety risks associated with antiemetic use: A cross-sectional study
Highlighted a high prevalence of self-medication, with most participants keeping these drugs at home due to their accessibility and low cost. A strong correlation was observed between educational level and awareness; individuals with higher education were more likely to seek professional advice and carefully read drug leaflets. Conversely, lower educational groups and younger participants showed a greater tendency to repeat doses without consultation or rely on home remedies.
Kidney Diseases
Kidney diseases is a “hidden epidemic” affecting 850 million people worldwide. It occurs when the kidneys become damaged and can’t perform their function. Damage may be caused by diabetes, high blood pressure, and various other chronic conditions. Kidney diseases can lead to other health problems, including weak bones, nerve damage, and malnutrition. There are two main types of kidney diseases: short-term (acute kidney failure) and lifelong (chronic kidney failure). If the diseases get worse over time, the kidneys may stop working completely. This means that dialysis will be required to perform the function of the kidneys or kidney transplant. Dialysis is a treatment that filters and purifies the blood using a machine. It can’t cure kidney diseases, but it can prolong the life.
Kidney complications & transplantation
Kidney diseases are worldwide public health problems with a high cost and increasing incidence. By revealing the genetic and cellular mechanism behind mammalian kidney development, better diagnostic methods and novel therapies can be expected to be developed. The mammalian kidney is a typical organ that develops on the basis of sequential and reciprocal cell and tissue interactions. Pyelonephritis, Glomerulonephritis, Kidney stones, Nephrotic syndrome, and Acute or chronic kidney failure are the most complications in the kidney kingdom, so that living kidney transplantation has become the preferred treatment for those patients who can’t have the powerful capacity of the kidney function, and here it has a very rejection risk in the first month and we can controlled in this situation with long term immunosuppressant therapy involved in the post-transplantation protocol.
