Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to bone fragility, and consequent increase in fracture risk. It is the most common reason for a broken bone among the elderly. Bones that commonly break include the vertebrae in the spine, the bones of the forearm, and the hip. Until a broken bone occurs there are typically no symptoms. Bones may weaken to such a degree that a break may occur with minor stress or spontaneously. After the broken bone heals, the person may have chronic pain and a decreased ability to carry out normal activities.
Orthomolecular medicine is a form of alternative medicine that aims to maintain human health through nutritional supplementation. The concept builds on the idea of an optimal nutritional environment in the body and suggests that diseases reflect deficiencies in this environment. Treatment for disease, according to this view, involves attempts to correct "imbalances or deficiencies based on individual biochemistry" by use of substances such as vitamins, minerals, amino acids, trace elements and fatty acids. The notions behind orthomolecular medicine are not supported by sound medical evidence, and the therapy is not effective; even the validity of calling the orthomolecular approach a form of medicine has been questioned since the 1970s.
PubMed is a free search engine accessing primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintain the database as part of the Entrez system of information retrieval.
Diphyllobothrium is a genus of tapeworms which can cause diphyllobothriasis in humans through consumption of raw or undercooked fish. The principal species causing diphyllobothriasis is D. latum, known as the broad or fish tapeworm, or broad fish tapeworm. D. latum is a pseudophyllid cestode that infects fish and mammals. D. latum is native to Scandinavia, western Russia, and the Baltics, though it is now also present in North America, especially the Pacific Northwest. In Far East Russia, D. klebanovskii, having Pacific salmon as its second intermediate host, was identified.
Focal segmental glomerulosclerosis (FSGS), also known as “focal glomerular sclerosis” or “focal nodular glomerulosclerosis,” is a histopathologic finding of scarring (sclerosis) of glomeruli and damage to renal podocytes. This process damages the filtration function of the kidney, resulting in protein loss in the urine. FSGS is a leading cause of excess protein loss--nephrotic syndrome—in children and adults. Signs and symptoms include proteinuria, water retention, and edema. Kidney failure is a common long-term complication of disease. FSGS can be classified as primary versus secondary depending on whether a particular toxic or pathologic stressor can be identified as the cause. Diagnosis is established by renal biopsy, and treatment consists of glucocorticoids and other immune-modulatory drugs. Response to therapy is variable, with a significant portion of patients progressing to end-stage kidney failure. FSGS is estimated to occur in 2-3 persons per million, with males and African peoples at higher risk.
PubMed Central (PMC) is a free digital repository that archives open access full-text scholarly articles that have been published in biomedical and life sciences journals. As one of the major research databases developed by the National Center for Biotechnology Information (NCBI), PubMed Central is more than a document repository. Submissions to PMC are indexed and formatted for enhanced metadata, medical ontology, and unique identifiers which enrich the XML structured data for each article. Content within PMC can be linked to other NCBI databases and accessed via Entrez search and retrieval systems, further enhancing the public's ability to discover, read and build upon its biomedical knowledge.
Megavitamin therapy is the use of large doses of vitamins, often many times greater than the recommended dietary allowance (RDA) in the attempt to prevent or treat diseases. Megavitamin therapy is typically used in alternative medicine by practitioners who call their approach orthomolecular medicine. Vitamins are useful in preventing and treating illnesses specifically associated with dietary vitamin shortfalls, but the conclusions of medical research are that the broad claims of disease treatment by advocates of megavitamin therapy are unsubstantiated by the available evidence. It is generally accepted that doses of any vitamin greatly in excess of nutritional requirements will result either in toxicity or in the excess simply being metabolised; thus evidence in favour of vitamin supplementation supports only doses in the normal range. Critics have described some aspects of orthomolecular medicine as food faddism or even quackery. Research on nutrient supplementation in general suggests that some nutritional supplements might be beneficial, and that others might be harmful; several specific nutritional therapies are associated with an increased likelihood of the condition they are meant to prevent.
CD137 is a member of the tumor necrosis factor (TNF) receptor family. Its alternative names are tumor necrosis factor receptor superfamily member 9 (TNFRSF9), 4-1BB and induced by lymphocyte activation (ILA). It is of interest to immunologists as a co-stimulatory immune checkpoint molecule.

The term macromolecular assembly (MA) refers to massive chemical structures such as viruses and non-biologic nanoparticles, cellular organelles and membranes and ribosomes, etc. that are complex mixtures of polypeptide, polynucleotide, polysaccharide or other polymeric macromolecules. They are generally of more than one of these types, and the mixtures are defined spatially, and with regard to their underlying chemical composition and structure. Macromolecules are found in living and nonliving things, and are composed of many hundreds or thousands of atoms held together by covalent bonds; they are often characterized by repeating units. Assemblies of these can likewise be biologic or non-biologic, though the MA term is more commonly applied in biology, and the term supramolecular assembly is more often applied in non-biologic contexts. MAs of macromolecules are held in their defined forms by non-covalent intermolecular interactions, and can be in either non-repeating structures, or in repeating linear, circular, spiral, or other patterns. The process by which MAs are formed has been termed molecular self-assembly, a term especially applied in non-biologic contexts. A wide variety of physical/biophysical, chemical/biochemical, and computational methods exist for the study of MA; given the scale of MAs, efforts to elaborate their composition and structure and discern mechanisms underlying their functions are at the forefront of modern structure science.

Yup'ik cuisine refers to the Eskimo style traditional subsistence food and cuisine of the Yup'ik people from the western and southwestern Alaska. Also known as Cup'ik cuisine for the Chevak Cup'ik dialect speaking Eskimos of Chevak and Cup'ig cuisine for the Nunivak Cup'ig dialect speaking Eskimos of Nunivak Island. This cuisine is traditionally based on meat from fish, birds, sea and land mammals, and normally contains high levels of protein. Subsistence foods are generally considered by many to be nutritionally superior superfoods. Yup’ik diet is different from Alaskan Inupiat, Canadian Inuit, and Greenlandic diets. Fish as food are primary food for Yup'ik Eskimos. Both food and fish called neqa in Yup'ik. Food preparation techniques are fermentation and cooking, also uncooked raw. Cooking methods are baking, roasting, barbecuing, frying, smoking, boiling, and steaming. Food preservation methods are mostly drying and less often frozen. Dried fish is usually eaten with seal oil. The ulu or fan-shaped knife used for cutting up fish, meat, food, and such.

Steven Grinspoon (M.D.) is a Professor of Medicine at Harvard Medical School, Chief of the Massachusetts General Hospital (MGH) Metabolism Unit, and Director of the Nutrition Obesity Research Center at Harvard. In addition, he is the MGH Endowed Chair in Neuroendocrinology and Metabolism. His work investigates the neuroendocrine regulation of body composition, and physiologic consequences of fat distribution on cardiovascular disease and inflammation. He has investigated the effects of reduced growth hormone on metabolic dysregulation in obesity and was the first to propose the use of a Growth Hormone-releasing Hormone (GHRH) analogue to increase endogenous GH secretion on lipodystrophy and generalized obesity, which led to the FDA approval of Tesamorelin for excess visceral fat accumulation in HIV-infected patients. This work has now been extended to show robust effects on Non-alcoholic fatty liver disease (NAFLD). More recently, his research focuses on the inflammatory mechanisms by which ectopic fat and other metabolic perturbations contribute to HIV-Cardiovascular disease (CVD), and in this regard, he led the AHA State of the Science Conference on CVD in HIV. Additionally, he is leading the large multicenter REPRIEVE study, the first study of a primary prevention strategy for CVD in HIV. He has also investigated increased Renin-Angiotensin-Aldosterone System (RAAS) activation and immune activation in relationship to visceral fat accumulation, and the mechanisms of subcutaneous adipose dysfunction involving DICER. Dr. Grinspoon has served on the Harvard faculty since 1995 and has been selected to the American Society for Clinical Investigation and the Association of American Physicians for his scientific contributions. He received the American Federation of Medical Research Investigator of the Year Award in 2005 and the Edward H.
