    For practical reasons Spinacia oleracea was chosen for these pot experiments in a greenhouse. For the quantitative estimation of carotene, a short method was developed. The vitamin C content of leaves decreased rapidly at room temperature and even at ice-box temperature, so analysis had to be rapid

  3. Vitamins

    Directory of Open Access Journals (Sweden)

    Ruiz-Roso, Baltasar

    1998-08-01

    Full Text Available A thermal treatment is an intrinsic part of most food processing procedures and may be employed to inactive enzimes and toxic '• factors, to change texture and flavour or to preserve. The vitamin degree of transformation or destruction in cooking methods depends on the temperature and on the time of exposure to this temperature. Oxigen, light and transition metals frequently play an active role in accelerating or promoting vitamin losses. Both chemical change and difussion proceed more rapidly as the temperature is raised. An advantage of deep frying consists of the fact that the temperature within the food does not exceed the temperature of the steam under the crust, and that frying times are in general very short compared to other cooking procedures. Another advantages may be the low content of dissolved oxygen in frying fats, and also in its high tocopherol content. There is no leaching of water-soluble vitamins in deep-frying. Speaking of vitamin stability we have to keep in mind that the concept of vitamins is a more physiological concept than a chemical one. The stability itself is not a property of the various vitamins but rather of the various chemical compounds sometimes called vitamers, of which a certain vitamin group consists. For practical purposes, vitamin losses should be considered only in foods wich substantially contribute to the vitamin supply of single people or population groups. There is little data in the literature about vitamin changes in deep-frying of food. However published experimental data on vitamin loses show that deep-frying is one of the most protective cooking procedures. For example, in ours results the vitamin C losses of stewed vegetable foods were twice higher than that of fried ones, (raw potatoes containing 19 mg/100g fresh weight, 13 mg/100 fried in olive oil, and 5 mg/100g stewed in the same oil.

Afhandlingen indleder med at beskrive de unges liv i en globalisering. Mange unge mennesker uden en social ansvarlig baggrund har ikke lært...... at foretage sig nødvendige samfundsmæssige valg. På grund af nederlag i hjem, skole, uddannelse og erhverv søger unge fællesskaber i ligestillede miljøer svarende til egen negative forventningspraksis.

    Bo, Inger Glavind

    2016-01-01

    I kapitlet gennemgås en socialkonstruktivistisk forståelse af narrativer. I kapitlet vil jeg gennemgå centrale teoretiske pointer, der samlet set er grundlæggende for en social konstruktivistisk forståelse af narrativer for herved at udfolde forståelsen af den narrative tilgang og desuden...... tydeliggøre, hvordan tilgangen er forbundet med en særlig forståelse af identitetsskabelse. Der er tale om pointer der almindeligvis forbindes med ”små fortællinger” i form af længere identitetsfortællinger og narrative interviews. Kapitlet gennemgår således centrale inspirationskilder og teoretiske pointer...

  14. Den iscenesatte folkelighed

    Directory of Open Access Journals (Sweden)

    Néstor Garcia Canclini

    1994-09-01

    Full Text Available Hvad er "det folkelige" og hvad er "folkekultur"? Néstor Garcia Canclini har i denne artikel sat sig for at dekonstruere begrebet "det folkelige" og beskrive den måde, forskellige grupper bruger og misbruger begrebet på. Han analyserer tre fremherskende idéer om folkelighed: folkloristernes romantiske idé om det oprindelige, der blev ødelagt af massekulturen, massemediernes popularitetsbegreb og endelig populisternes - både de højre- og venstreorienteredes - iscenesættelse af folkeligheden. Desuden ser han på to marxistiske skolers opfattelse af forholdet mellem de dominerende og undertrykte klasser og forskellige definitioner af folkelig- hed. Ligesom Anamaria Fadul argumenterer Canclini for nødvendigheden af en ny, tværdiciplinær forskning, som opfanger kompleksitet og flerty- digheder i forholdet mellem de undertrykte og dominerende og ser "det folkelige" som en tragisk komedie med modsætninger og flertydighed snarere end en evigt fremadskrivende episk fortælling. Artiklen er en forkortet udgave af kapitel 5 i Canclinis bog fra 1989: "Culturas Hibridas - Estrategias para entrat y salir de la modernidad. Mexico: Grijalbo.

  16. Hydrosoluble vitamins.

    Science.gov (United States)

    Chawla, Jasvinder; Kvarnberg, David

    2014-01-01

    The hydrosoluble vitamins are a group of organic substances that are required by humans in small amounts to prevent disorders of metabolism. Significant progress has been made in our understanding of the biochemical, physiologic and nutritional aspects of the water-soluble vitamins. Deficiency of these particular vitamins, most commonly due to inadequate nutrition, can result in disorders of the nervous system. Many of these disorders have been successfully prevented in developed countries; however, they are still common in developing countries. Of the hydrosoluble vitamins, the nervous system depends the most on vitamins B and C (ascorbic acid) for proper functioning. The B group vitamins include thiamin (vitamin B1), riboflavin (vitamin B2), niacin or niacinamide (vitamin B3), pantothenic acid (vitamin B5), pyridoxine or pyridoxal (vitamin B6) and cobalamin (vitamin B12). Clinical findings depend upon the deficiency of the underlying vitamin; generally, deficiency symptoms are seen from a combination rather than an isolated vitamin deficiency. True hereditary metabolic disorders and serious deficiency-associated diseases are rare and in general limited to particular geographic regions and high-risk groups. Their recognition is truly important as that determines the appropriate therapeutic management. The general availability of vitamins to practically everyone and several national health programs have saved many lives and prevented complications. However, there has been some apprehension for several decades about how harmless generous dosages of these vitamins are. Overt overdosages can cause vitamin toxicity affecting various body systems including the nervous system. Systemically, vitamin toxicity is associated with nonspecific symptoms, such as nausea, vomiting, diarrhea, and skin rash which are common with any acute or chronic vitamin overdose. At a national level, recommended daily allowances for vitamins become policy statements. Nutrition policy has far

    1986-01-01

    Radiotelemetry was used to locate 101 grizzly bear (Ursus arctos) dens from 1975 to 1980; 35 dens were examined on the ground. Pregnant females denned in late October, and most other bears denned by mid-November. Duration of denning average 113, 132, and 170 days for males, females, and females with new cubs, respectively. Males emerged from mid-February to late March, followed by single females and females with yearlings and 2-year-olds. Females with new cubs emerged from early mid-April. Den sites were associated with moderate tree cover (26%-75% canopy cover) on 30°-60° slopes. Dens occurred on all aspects, although northerly exposures were most common. Grizzly bears usually dug new dens but occasionally used natural cavities or a den from a previous year. Males usually dug larger dens than females with young. Eight excavated and 2 natural dens of the 35 examined dens were used for more than 1 year.

  20. Polar bear maternity denning in the Beaufort Sea

    Science.gov (United States)

    Amstrup, Steven C.; Gardner, Craig L.

    1994-01-01

    The distribution of polar bears (Ursus maritimus) is circumpolar in the NOrthern Hemisphere, but known locations of maternal dens are concentrated in relatively few, widely scattered locations. Denning is either uncommon or unknown within gaps. To understand effects of industrial development and propose increases in hunting, the temporal and spatial distribution of denning in the Beaufort Sea must be known. We caputred and radiocollared polar bears between 1981 and 1991 and determined tht denning in the Beaufort Sea region was sufficient to account for the estimated population there. Of 90 dend, 48 were on drifting pack ice, 38 on land, and 4 on land-fast ice. The portions of dens on land was higher (P= 0.029) in later compared with earlier years of the study. Bears denning on pack ice drifting as far as 997 km (x=385km) while in dens. there was no difference in cun production by bears denning on land and pack ice (P =0.66). Mean entry and exit dates were 11 November and 5 April for land dens and 22 November and 26 March for pack-ice dens. Female polar bears captured in the Beaufort Sea appeared to be isolated from those caught eat of Cape Bathurst in Canada. Of 35 polar bears that denned along the mainland coast of Alaska and Canada 80% denned between 137 00'W snf 146 59'W. Bears followed to >1 den did not reuse sites and consecutive dens were 20-1,304 km apart. However radio-collared bears are largely faithful to substrate (pack-ice, land, and land-fast ice) and the general geographic area of previous dens. Bears denning on land may be vunerable to human activities such as hunting and industrial development. However, predictable denning chronology and alck of site fidelity indicate that many potential impacts on denning polar bears could be mitigated.

  17. Human disturbances of denning polar bears in Alaska

    International Nuclear Information System (INIS)

    Amstrup, S.C.

    1993-01-01

    Polar bears (Ursus maritimus) give birth in dens of snow and ice. The altricial neonates cannot leave the den for >2 months post-partum and are potentially vulnerable to disturbances near dens. The coastal plain (1002) area of Alaska's Arctic National Wildlife Refuge (ANWR) lies in a region of known polar bear denning and also may contain >9 billion barrels of recoverable oil. Polar bears in dens could be affected in many ways by hydrocarbon development. The distribution of dens on ANWR was documented between 1981 and 1992 and responses of bears in dens to various anthropogenic disturbances were observed. Of 44 dens located by radiotelemetry on the mainland coast of Alaska and Canada, 20 (45%) were on ANWR and 15 (34%) were within the 1002 area. Thus, development of ANWR will increase the potential that denning polar bears are disturbed by human activities. However, perturbations resulting from capture, marking, and radiotracking maternal bears did not affect litter sizes or stature of cubs produced. Likewise, 10 of 12 denned polar bears tolerated exposure to exceptional levels of activity. This tolerance and the fact that investment in the denning effort increases through the winter indicated that spatial and temporal restrictions on developments could prevent the potential for many disruptions of denned bears from being realized. 16 refs., 1 fig., 2 tabs

    2015-01-01

    Full Text Available Dens evaginatus is an uncommon developmental anomaly of human dentition characterized by the presence of tubercle on the occlusal surface of mandibular premolars and lingual surface of anterior teeth. Due to occlusal trauma this tubercle tends to fracture thus exposing the pathway to the pulp chamber of teeth. This case report is about the presentation of dens evaginatus in mandibular premolars bilaterally; among them tooth 44 was associated with chronic apical periodontitis. Fractured tubercle of three premolars was sealed with composite resin. Root canal treatment was performed with tooth 44. Routine endodontic treatment did not result in remission of infection. Therefore, culture and sensitivity tests were performed to identify the cause and modify treatment plan accordingly. Triple antibiotic paste was used as an intracanal medicament to disinfect the root canal that resulted in remission of infection.

  6. Simultaneous Occurrence of Dens Invaginatus and Fusion

    Directory of Open Access Journals (Sweden)

    Amit Mhapuskar

    2013-01-01

    Full Text Available Although Dens invaginatus and fusion are well-known and well established dental anomalies, they are rarely seen in supernumerary teeth. In this article, simultaneous occurrence of Dens invaginatus and fusion between maxillary lateral incisor and a supernumerary tooth is described. Dens invaginatus is clinically significant due to the possibility of the pulpal involvement; pulpitis, necrotic pulps and chronic periapical lesions are often associated with this anomaly without clinical symptoms. Fusion has a negative impact on the aesthetics, especially when it occurs in maxillary anterior teeth. It is difficult to clinically make differential diagnosis between fused teeth and geminated teeth, especially when these anomalies take place together with hypodontia or supernumerary tooth. It has been found that sequel of such teeth may result in delayed eruption, ectopic eruption or even impaction of permanent teeth; hence proper diagnosis by clinical and radiographic methods and intervention at appropriate time is of paramount importance. The accurate knowledge of variations in morphology of tooth and pulp cavity greatly assists the dentist in planning successful treatment options.

Diese Zeichen wirken als Zeichen der Resozialisierung, die die bestehenden Identitäten löschen und sich an der Schaffung neuer Strukturen beteiligen. Die Zeit der Romantik in Europa ermöglichte die Schaffung von Nationalstaaten und ihr Hauptmerkmal war die Nationalsprache. Diese Art der sozialen Differenzierung hatte das Ziel, die Illusion einer vollständig homogenisierten Gesellschaft zu schaffen und damit den Prozess der Zerstörung der „kleinen“ Sprachen zu beginnen. Sprache und Kultur erwiesen sich als Grundlage der Gemeinschaftserhaltung. Die Homogenisierung ermöglicht Aktivitäten mit dem Ziel, einem Individuum zu helfen, sich als Individuum und als Mitglied der Gemeinschaft zu behaupten.

    Wild wolves (Canis lupus) that had produced pups in earlier years but were not currently pregnant, and ovariectomized captive wolves, dug dens during and after the whelping season even though they produced no pups. These observations suggest that den digging is not a function of pregnancy or of ovarian estrogen or progesterone. We hypothesize that increasing prolactin in spring elicits or mediates den-digging behavior.

Currently there are no clear recommendations for increase of fat-solubile vitamins intake in athletes, as well as evidence that athletic performance may be improved due to fat-solubile vitamins supplementation. In a small number of studies, it was shown that an antioxidant effect of beta carotene and vitamin E can prevent muscle damage and facilitate recovery after exercise. Also, athletes who perform the exercises in the halls should be informed about the necessity of sun exposure, as vitamin D is synthesised in the skin. Most athletes are not familiar with their needs for vitamins and trace elements, and take these compounds as supplements without consulting a nutritionist. It is important to emphasize that liposulubile vitamins are deposited in the body and can cause hypervitaminosis and toxic effects if taken in excess. It is indisputable that the lack of any fat-soluble vitamin cause problems in normal physiological processes, but supplementation is generally not required in athlets who have a well-balanced diet.

    Full Text Available The consumption of a daily multivitamin among people all over the world is dramatically increasing in recent years. Most of the people believe that if vitamins are not effective, at least they are safe. However, the long term health consequences of vitamins consumption are unknown. This study aimed to assess the side effects and possible harmful and detrimental properties of vitamins and to discuss whether vitamins can be used as safe health products or dietary supplements. We performed a MEDLINE/PubMed, EMBASE, Scopus and Google Scholar search and assessed reference lists of the included studies which were published from 1993 through 2015. The studies, with an emphasis on RCTs (randomized controlled clinical trials, were reviewed. As some vitamins such as fat-soluble vitamins (vitamin A, vitamin D, vitamin E, and also some of the water-soluble vitamins like folic acid may cause adverse events and some like vitamin C is widely taken assuming that it has so many benefits and no harm, we included relevant studies with negative or undesired results regarding the effect of these vitamins on health. Our recommendation is that taking high-dose supplements of vitamins A, E, D, C, and folic acid is not always effective for prevention of disease, and it can even be harmful to the health.

    2001-01-01

    The aim of this paper is to propose a single stage global treatment of endodontic, periapical and periodontal lesions in a lateral maxillary incisor with dens invaginatus. A 24 year-old woman presenting a lateral maxillary incisor with dens invaginatus in association with periapica1 and periodontal lesions underwent simultaneous surgical, endodontic and periodontal regenerative procedures. At 2, 6, 12, 18 months follow-up the radiographic healing appeared to be improved and the periapical lesion healed completely 1 year after surgical intervention. Surgery in association with endodontic and periodontal procedures represents the treatment of choice to maximize long term prognosis in cases of dens invaginatus with chronic periapical and periodontal lesions.

    2004-01-01

    The objective of this study is to analyze the biomechanics of dens fractures of the second cervical vertebra in the adult population due to motor vehicle crashes. Case-by-case records from the Crash Injury Research and Engineering Network (CIREN) and National Automotive Sampling System (NASS) databases were used. Variables such as change in velocity, impact direction and body habitus were extracted. Results indicated that similarities exist in the two databases despite differences in sampling methods between the two sources (e.g., CIREN is not population based). Trauma is predominantly associated with the frontal mode of impact. Majority of injuries occur with change in velocities below current federal guideline thresholds. No specific bias exists with respect to variables such as age, height, weight, and gender. Because similar conclusions can be drawn with regard to vehicle model years, design changes during these years may have had little effect on this injury. To ameliorate trauma, emphasis should be placed on the frontal impact mode and entire adult population. Because of clinical implications in the fracture type (II being most critical) and lack of specific coding, CIREN data demonstrates the need to improve injury coding in the AIS and application in the NASS to enhance occupant safety and treatment in the field of automotive medicine.

    Hemilä, Harri

    2017-03-29

    In the early literature, vitamin C deficiency was associated with pneumonia. After its identification, a number of studies investigated the effects of vitamin C on diverse infections. A total of 148 animal studies indicated that vitamin C may alleviate or prevent infections caused by bacteria, viruses, and protozoa. The most extensively studied human infection is the common cold. Vitamin C administration does not decrease the average incidence of colds in the general population, yet it halved the number of colds in physically active people. Regularly administered vitamin C has shortened the duration of colds, indicating a biological effect. However, the role of vitamin C in common cold treatment is unclear. Two controlled trials found a statistically significant dose-response, for the duration of common cold symptoms, with up to 6-8 g/day of vitamin C. Thus, the negative findings of some therapeutic common cold studies might be explained by the low doses of 3-4 g/day of vitamin C. Three controlled trials found that vitamin C prevented pneumonia. Two controlled trials found a treatment benefit of vitamin C for pneumonia patients. One controlled trial reported treatment benefits for tetanus patients. The effects of vitamin C against infections should be investigated further.

    The central and local stress limiting systems, including the antioxidant defense system involved in defending the organism at the cellular and systemic levels from excess activation response to stress influence, leading to damaging effects. The development of stress, regardless of its nature [cold, increased physical activity, aging, the development of many pathologies (cardiovascular, neurodegenerative diseases, diseases of the gastrointestinal tract, ischemia, the effects of burns), immobilization, hypobaric hypoxia, hyperoxia, radiation effects etc.] leads to a deterioration of the vitamin status (vitamins E, A, C). Damaging effect on the antioxidant defense system is more pronounced compared to the stress response in animals with an isolated deficiency of vitamins C, A, E, B1 or B6 and the combined vitamins deficiency in the diet. Addition missing vitamin or vitamins restores the performance of antioxidant system. Thus, the role of vitamins in adaptation to stressors is evident. However, vitamins C, E and beta-carotene in high doses, significantly higher than the physiological needs of the organism, may be not only antioxidants, but may have also prooxidant properties. Perhaps this explains the lack of positive effects of antioxidant vitamins used in extreme doses for a long time described in some publications. There is no doubt that to justify the current optimal doses of antioxidant vitamins and other dietary antioxidants specially-designed studies, including biochemical testing of initial vitamin and antioxidant status of the organism, as well as monitoring their change over time are required.

    Vitamins are organic substances essential to the maintenance of many physiological functions, and necessary for growth. They are subdivided into two groups: the fat soluble vitamins which include vitamins A, D, E and K and the water-soluble vitamins which include Group B vitamins and vitamin C. The recommendations for vitamins intake must be evaluated at regular intervals, and vary according to the different methods used and the different environments assessed. The shortcomings, but equally the measures of prevention must be taken into account. In industrialized countries, provided that the diet is balanced and in the absence of chronic disease, the majority of needs are covered. Vitamin requirements vary depending on age, sex, state of pregnancy, chronic disease or a specific diet. In industrialized countries, chronic alcoholics and malabsorption cases represent groups at risk of vitamin deficiency. Dietary anamnesis remains the best tool to assess needs and nutritional deficiencies. In infants fed exclusively on milk, the required intake is easy to deduce; on the other hand, the needs assessment becomes more difficult with dietary diversification. In industrialized countries, vitamin D should be administered throughout one's life, and vitamin K during the first three months of life for breast-fed new-borns. In developing countries, nutritional status is precarious and supplementation needs to be adapted accordingly.

  14. Nonclassical Vitamin D Actions

    Directory of Open Access Journals (Sweden)

    Armin Zittermann

    2010-03-01

    Full Text Available It is becoming increasingly clear that vitamin D has a broad range of actions in the human body. Besides its well-known effects on calcium/phosphate homeostasis, vitamin D influences muscle function, cardiovascular homeostasis, nervous function, and the immune response. Vitamin D deficiency/insufficiency has been associated with muscle weakness and a high incidence of various chronic diseases such as cardiovascular disease, cancer, multiple sclerosis, and type 1 and 2 diabetes. Most importantly, low vitamin D status has been found to be an independent predictor of all-cause mortality. Several recent randomized controlled trials support the assumption that vitamin D can improve muscle strength, glucose homeostasis, and cardiovascular risk markers. In addition, vitamin D may reduce cancer incidence and elevated blood pressure. Since the prevalence of vitamin D deficiency/insufficiency is high throughout the world, there is a need to improve vitamin D status in the general adult population. However, the currently recommended daily vitamin D intake of 5–15 µg is too low to achieve an adequate vitamin D status in individuals with only modest skin synthesis. Thus, there is a need to recommend a vitamin D intake that is effective for achieving adequate circulating 25-hydroxyvitamin D concentrations (>75 nmol/L.

    2002-01-01

    Den entrance and emergence dates of grizzly bears (Ursus arctos) in the Greater Yellowstone Ecosystem are important to management agencies that wish to minimize impacts of human activities on bears. Current estimates for grizzly bear denning events use data that were collected from 1975–80. We update these estimates by including data obtained from 1981–99. We used aerial telemetry data to estimate week of den entry and emergence by determining the midpoint between the last known active date and the first known date denned, as well as the last known date denned and the first known active date. We also investigated post emergence movement patterns relative to den locations. Mean earliest and latest week of den entry and emergence were also determined. Den entry for females began during the fourth week in September, with 90% denned by the fourth week of November. Earliest den entry for males occurred during the second week of October, with 90% denned by the second week of December. Mean week of den entry for known pregnant females was earlier than males. Earliest week of den entry for known pregnant females was earlier than other females and males. Earliest den emergence for males occurred during the first week of February, with 90% of males out of dens by the fourth week of April. Earliest den emergence for females occurred during the third week of March; by the first week of May, 90% of females had emerged. Male bears emerged from dens earlier than females. Denning period differed among classes and averaged 171 days for females that emerged from dens with cubs, 151 days for other females, and 131 days for males. Known pregnant females tended to den at higher elevations and, following emergence, remained at higher elevation until late May. Females with cubs remained relatively close (grizzly bear populations in the southern Rocky Mountains.

  18. Fox Den Disease: An Interesting Case Following Delayed Diagnosis.

    Stehr, Ryan C; Kim, Nicholas; LoGiudice, John A; Ludwig, Kirk

    2015-06-01

    Pyoderma fistulans sinifica, also known as fox den disease, is a rare and poorly understood inflammatory disorder of the skin and subcutaneous tissues. This disorder is often mistaken for other inflammatory skin disorders and treated inappropriately. The authors describe the case of a 53-year-old male who presented to the colorectal surgery service with a longstanding diagnosis of perirectal Crohn's disease. Despite aggressive immunosuppression and numerous surgical procedures, the patient continued to have unrelenting purulent drainage from the skin of his buttocks. Following wide excision of the affected skin and subcutaneous tissues by the colorectal surgeon, the plastic surgery team reconstructed the 30 cm x 55 cm wound using a combination of local flaps and skin grafts. The initial pathology report of the excised specimen confirmed the presence of nonspecific abscesses and inflammation. Upon special request by the plastic surgery team, the sample was resectioned with the specific intent of establishing a diagnosis of fox den disease. The additional slides met the criteria for an unequivocal diagnosis of fox den disease. Immunosuppression was discontinued and the patient healed his wounds without complication. Fox den disease is often overlooked because of the obscurity of the disease and the special histological sectioning needed to establish a diagnosis. In this case, the patient was unnecessarily treated with immunosuppressive drugs for more than 3 decades because of a misdiagnosis. With increased awareness of fox den disease, perhaps its pathophysiology can be better elucidated as more patients are appropriately diagnosed and treated.

    The use of topically applied vitamins has become a ubiquitous part of clinical skin care. While a part of the skin's antioxidant system that assists in protecting it from oxidative damage, vitamins A, C, and E have also proven their ability to treat photoaging, acne, cutaneous inflammation, and hyperpigmentation ((Burgess, 2008). Understanding these vitamins' unique mechanisms of action and how they work in concert helps the clinician select the appropriate topicals for their patients.

    Full Text Available Subclasses of vitamin K, their origins, their differential characteristics of absorption and metabolism, their relative effects on gammacarboxylation of various proteins implicated in hemostasis andcoagulation, in bone calcification are not well known even by experts in these fields. These misunderstandings explain errors in recommendations for public and for patients. This review will not expose again the fundamentals on vitamins K as presented in the paper by Marc Guillaumont published in 2000 in this same journal. This 2011 review will try to update our actual knowledge and most of all will insist on their practical implications especially on the management of oral anticoagulant treatments since until recently vitamin K antagonist was the only available type of such a treatment. Several examples illustrate the need for a better understanding of this subject. The fear that diet vitamin K could deregulate the equilibrium of oral vitamin K antagonist treatment leads to recommend a quite total suppression of vitamin K containing components in the diet of anticoagulated patients. This leads to an opposite effect: a high sensitivity to vitamin K and to disequilibrium of the anticoagulant treatment while a comprehensivemoderate and regular diet intake of vitamin K first facilitates the food choice of the patients but also helps to stabilise the treatment of chronically anticoagulated patients. Vitamin K plays a role in bone calcification and in osteoporosis prevention. Until recently the food supplementation with vitamin K in view of preventing osteoporosis in general population was strongly limited due to fear to affect the treatment equilibrium in anticoagulated patients. While an understanding that the effects of moderate supplementation in vitamin K has no or limited effect on anticoagulation and on the long run could at the opposite help to stabilize the daily level of anticoagulation in patients chronically treated with vitamin K.

    Bridges, A.S.; Fox, J.A.; Olfenbuttel, C.; Vaughan, M.B.

    2004-01-01

    Researchers examining American black bear (Ursus americanus) denning behavior have relied primarily on den-site visitation and radiotelemetry to gather data. Repeated den-site visits are time-intensive and may disturb denning bears, possibly causing den abandonment, whereas radiotelemetry is sufficient only to provide gross data on den emergence. We used remote cameras to examine black bear denning behavior in the Allegheny Mountains of western Virginia during March-May 2003. We deployed cameras at 10 den sites and used 137 pictures of black bears. Adult female black bears exhibited greater extra-den activity than we expected prior to final den emergence, which occurred between April 12 and May 6, 2003. Our technique provided more accurate den-emergence estimation than previously published methodologies. Additionally, we observed seldom-documented behaviors associated with den exits and estimated cub age at den emergence. Remote cameras can provide unique insights into denning ecology, and we describe their potential application to reproductive, survival, and behavioral research.

    Full Text Available Vitamin D insufficiency is common in women across different races of childbearing age. It is being increasingly discovered that vitamin D has many important bodily functions apart from skeletal actions pertaining to Calcium homeostasis. Evidence suggests that the maternal risks due to vitamin D deficiency includes eclampsia, increased risk of gestational diabetes mellitus, glucose intolerance; and fetal risks include risk of rickets, osteoporotic fracture in late adulthood. It may be prudent to include screening of all pregnant women for vitamin D level as a part of routine antenatal care and supplementation be given if found deficient.

    Full Text Available Vitamin E is an important fat-soluble antioxidant and has been in use for more than 50 years in dermatology. It is an important ingredient in many cosmetic products. It protects the skin from various deleterious effects due to solar radiation by acting as a free-radical scavenger. Experimental studies suggest that vitamin E has antitumorigenic and photoprotective properties. There is a paucity of controlled clinical studies providing a rationale for well-defined dosages and clinical indications of vitamin E usage in dermatological practice. The aim of this article is to review the cosmetic as well as clinical implications of vitamin E in dermatology.

    Full Text Available Vitamins are necessary factors in human development and normal brain function. Vitamin C is a hydrosoluble compound that humans cannot produce; therefore, we are completely dependent on food intake for vitamin C. Ascorbic acid is an important antioxidative agent and is present in high concentrations in neurons and is also crucial for collagen synthesis throughout the body. Ascorbic acid has a role in modulating many essential neurotransmitters, enables neurogenesis in adult brain and protects cells against infection. While SVCT1 enables the absorption of vitamin C in the intestine, SVCT2 is primarily located in the brain.

    2005-07-01

    Full Text Available Dens evaginatus is a developmental anomaly that produces a tubercle on the occlusal surface of a tooth. It is found most frequently in the mandibular premolars. The occlusal tubercle easily causes occlusal interferences. Attrition or fracture of the tubercle can lead to pulpitis, pulp necrosis, periapical pathosis, and periapical infection. This case report illustrates the treatment of facial cellulitis arising from dens evaginatus with open apex. Calcium hydroxide was used for the apexification procedure. One year after canal obturation, radiography revealed no apical pathosis and the apical seal was evident.

    Science.gov (United States)

    Wacker, Matthias; Holick, Michael F.

    2013-01-01

    Vitamin D is the sunshine vitamin that has been produced on this earth for more than 500 million years. During exposure to sunlight 7-dehydrocholesterol in the skin absorbs UV B radiation and is converted to previtamin D3 which in turn isomerizes into vitamin D3. Previtamin D3 and vitamin D3 also absorb UV B radiation and are converted into a variety of photoproducts some of which have unique biologic properties. Sun induced vitamin D synthesis is greatly influenced by season, time of day, latitude, altitude, air pollution, skin pigmentation, sunscreen use, passing through glass and plastic, and aging. Vitamin D is metabolized sequentially in the liver and kidneys into 25-hydroxyvitamin D which is a major circulating form and 1,25-dihydroxyvitamin D which is the biologically active form respectively. 1,25-dihydroxyvitamin D plays an important role in regulating calcium and phosphate metabolism for maintenance of metabolic functions and for skeletal health. Most cells and organs in the body have a vitamin D receptor and many cells and organs are able to produce 1,25-dihydroxyvitamin D. As a result 1,25-dihydroxyvitamin D influences a large number of biologic pathways which may help explain association studies relating vitamin D deficiency and living at higher latitudes with increased risk for many chronic diseases including autoimmune diseases, some cancers, cardiovascular disease, infectious disease, schizophrenia and type 2 diabetes. A three-part strategy of increasing food fortification programs with vitamin D, sensible sun exposure recommendations and encouraging ingestion of a vitamin D supplement when needed should be implemented to prevent global vitamin D deficiency and its negative health consequences.

  9. Vitamin E Nicotinate

    Directory of Open Access Journals (Sweden)

    Kimbell R. Duncan

    2017-03-01

    Full Text Available Vitamin E refers to a family of compounds that function as lipid-soluble antioxidants capable of preventing lipid peroxidation. Naturally occurring forms of vitamin E include tocopherols and tocotrienols. Vitamin E in dietary supplements and fortified foods is often an esterified form of α-tocopherol, the most common esters being acetate and succinate. The vitamin E esters are hydrolyzed and converted into free α-tocopherol prior to absorption in the intestinal tract. Because its functions are relevant to many chronic diseases, vitamin E has been extensively studied in respect to a variety of diseases as well as cosmetic applications. The forms of vitamin E most studied are natural α-tocopherol and the esters α-tocopheryl acetate and α-tocopheryl succinate. A small number of studies include or focus on another ester form, α-tocopheryl nicotinate, an ester of vitamin E and niacin. Some of these studies raise the possibility of differences in metabolism and in efficacy between vitamin E nicotinate and other forms of vitamin E. Recently, through metabolomics studies, we identified that α-tocopheryl nicotinate occurs endogenously in the heart and that its level is dramatically decreased in heart failure, indicating the possible biological importance of this vitamin E ester. Since knowledge about vitamin E nicotinate is not readily available in the literature, the purpose of this review is to summarize and evaluate published reports, specifically with respect to α-tocopheryl nicotinate with an emphasis on the differences from natural α-tocopherol or α-tocopheryl acetate.

    2017-12-01

    Full Text Available Der Datenschutz in den sozialen Medien wirft eine Reihe von Problemen auf. Zum einen geht es um das Verhältnis des Datenschutzgesetzes zum Persönlichkeitsrecht; hier wird sich eine Kombinationslehre wie bei sonstigen besonderen Persönlichkeitsrechten – etwa dem Bildnisschutz – als überlegen erweisen. Die §§ 7 ff dTMG privilegieren die Provider in mehrfacher Hinsicht. Freilich bleibt deren Haftung oft unberührt. So kann der Content-Provider zur Verantwortung gezogen werden auch wenn er sich fremde Nachrichten nur zu eigen macht. Der Host-Provider haftet ab Kenntnis des rechtswidrigen Inhalts; auch treffen ihn eine Reihe von Prüfungspflichten. Entgegen der Auffassung des BGH ist er auch verpflichtet, den Namen des Content-Providers zu nennen. Schließlich kommt eine Haftung des Access-Providers in Betracht, wenn er die rechtswidrigen Inhalte wissentlich weiterleitet. Entgegen der Auffassung des EuGH besteht ein Gerichtsstand überall dort, wo sich die unerlaubte Handlung – die Verletzung des Persönlichkeitsrechts – verwirklicht; sie ist nicht auf den Tatort und den Ort beschränkt, an dem sich das Opfer befindet.

    Calcification around the odontoid process suggests 'crowned dens' syndrome, when accompanied with acute occipital headache or neck pain and with inflammatory signs. We retrospectively searched for calcification around the odontoid process in routine CT images of 282 patients emcompassing the craniovertebral junction, and found 13 (4.6%) had 'crowned dens' calcifications with neither characteristic symptoms nor signs suggestive for crowned dens' syndrome. Females of older ages frequently showed asymptomatic crowned dens' calcifications. (author)

  8. Vitamin C revisited.

    Science.gov (United States)

    Oudemans-van Straaten, Heleen M; Spoelstra-de Man, Angelique Me; de Waard, Monique C

    2014-08-06

    This narrative review summarizes the role of vitamin C in mitigating oxidative injury-induced microcirculatory impairment and associated organ failure in ischemia/reperfusion or sepsis. Preclinical studies show that high-dose vitamin C can prevent or restore microcirculatory flow impairment by inhibiting activation of nicotinamide adenine dinucleotide phosphate-oxidase and inducible nitric oxide synthase, augmenting tetrahydrobiopterin, preventing uncoupling of oxidative phosphorylation, and decreasing the formation of superoxide and peroxynitrite, and by directly scavenging superoxide. Vitamin C can additionally restore vascular responsiveness to vasoconstrictors, preserve endothelial barrier by maintaining cyclic guanylate phosphatase and occludin phosphorylation and preventing apoptosis. Finally, high-dose vitamin C can augment antibacterial defense. These protective effects against overwhelming oxidative stress due to ischemia/reperfusion, sepsis or burn seems to mitigate organ injury and dysfunction, and promote recovery after cardiac revascularization and in critically ill patients, in the latter partially in combination with other antioxidants. Of note, several questions remain to be solved, including optimal dose, timing and combination of vitamin C with other antioxidants. The combination obviously offers a synergistic effect and seems reasonable during sustained critical illness. High-dose vitamin C, however, provides a cheap, strong and multifaceted antioxidant, especially robust for resuscitation of the circulation. Vitamin C given as early as possible after the injurious event, or before if feasible, seems most effective. The latter could be considered at the start of cardiac surgery, organ transplant or major gastrointestinal surgery. Preoperative supplementation should consider the inhibiting effect of vitamin C on ischemic preconditioning. In critically ill patients, future research should focus on the use of short-term high-dose intravenous vitamin

  10. Dwellers in dens on sandy bottoms: Ecological and behavioural traits of Octopus vulgaris

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available Four visual censuses targeting Octopus vulgaris living in dens on sandy bottoms were carried out from June to October 2013 in the National Park of the Atlantic Galician Islands (NW Spain. Censuses were undertaken by scuba diving between 5 and 21 m depth in daytime. The total area swept was 13.75 ha. There were no significant differences between octopus presence in dens during open and closed fishing seasons. Depth had a significant negative relationship with occupancy. The average number of dens per 1000 m2 was 3.84±0.84 in June and 3.89 in October. The area per den was 260 m2. Den number estimations varied between 1586 and 2057. The largest number of dens (76.5% was found between 5 and 10 m depth. Den distribution was clumped. No significant differences were found between octopus size classes (small, medium and large and den diameter. Associate dens were observed. There were no significant differences in den diameter and shell types found around the middens. Many dens could be “permanent”. Drilling bivalve shell behaviour is discussed. The surveyed area had around 1100 individuals, mainly small specimens. No significant differences were found between octopus size and depth. Substrate, den type and food abundance and availability (especially razors Ensis arcuatus seem to be the main factors influencing dens and octopus density and distribution. Den availability does not appear to be a limiting factor in this case. Temperature, den availability, predators and fishing pressure influencing density and distribution are discussed. Rodas inlet may be a preferential habitat for O. vulgaris individuals ranging from 200 to 2000 g, but especially small specimens ( ≤ 1000 g.

    We investigated the combination effect of sodium ascorbate (vitamin C) and menadione (vitamin K3) on the viability of various cultured cells. Human oral squamous cell carcinoma (HSC-2, HSC-3) and human promyelocytic leukemia (HL-60) cells were more sensitive to these vitamins as compared to normal cells (human gingival fibroblast HGF, human periodontal ligament fibroblast HPLF, human pulp cell HPC). The combination of vitamin C and vitamin K3 produced synergistic cytotoxicity against all these 6 cell lines. Treatment with vitamin C or vitamin K3, or their combination, induced internucleosomal DNA fragmentation only in HL-60 cells, but not in the oral tumor cell lines (HSC-2, HSC-3, HSG). ESR spectroscopy showed that vitamins C and K3 produce radicals under alkaline conditions and that the combination of these two vitamins synergistically enhanced their respective radical intensities.

    2018-01-01

    Research carried out during the past two-decades extended the understanding of actions of vitamin D, from regulating calcium and phosphate absorption and bone metabolism to many pleiotropic actions in organs and tissues in the body. Most observational and ecological studies report association of higher serum 25-hydroxyvitamin D [25(OH)D] concentrations with improved outcomes for several chronic, communicable and non-communicable diseases. Consequently, numerous agencies and scientific organizations have developed recommendations for vitamin D supplementation and guidance on optimal serum 25(OH)D concentrations. The bone-centric guidelines recommend a target 25(OH)D concentration of 20ng/mL (50nmol/L), and age-dependent daily vitamin D doses of 400-800IU. The guidelines focused on pleiotropic effects of vitamin D recommend a target 25(OH)D concentration of 30ng/mL (75nmol/L), and age-, body weight-, disease-status, and ethnicity dependent vitamin D doses ranging between 400 and 2000IU/day. The wise and balanced choice of the recommendations to follow depends on one's individual health outcome concerns, age, body weight, latitude of residence, dietary and cultural habits, making the regional or nationwide guidelines more applicable in clinical practice. While natural sources of vitamin D can raise 25(OH)D concentrations, relative to dietary preferences and latitude of residence, in the context of general population, these sources are regarded ineffective to maintain the year-round 25(OH)D concentrations in the range of 30-50ng/mL (75-125nmol/L). Vitamin D self-administration related adverse effects, such as hypercalcemia and hypercalciuria are rare, and usually result from taking extremely high doses of vitamin D for a prolonged time.

  17. Selection of den sites by black bears in the southern Appalachians

    Reynolds-Hogland, M. J.; Mitchell, M.S.; Powell, R.A.; Brown, D.C.

    2007-01-01

    We evaluated selection of den sites by American black bears (Ursus americanus) in the Pisgah Bear Sanctuary, western North Carolina, by comparing characteristics of dens at 53 den sites with availability of habitat characteristics in annual home ranges of bears and in the study area. We also tested whether den-site selection differed by sex, age, and reproductive status of bears. In addition, we evaluated whether the den component of an existing habitat model for black bears predicted where bears would select den sites. We found bears selected den sites far from gravel roads, on steep slopes, and at high elevations relative to what was available in both annual home ranges and in the study area. Den-site selection did not differ by sex or age, but it differed by reproductive status. Adult females with cubs preferred to den in areas that were relatively far from gravel roads, but adult females without cubs did not. The habitat model overestimated the value of areas near gravel roads, underestimated the value of moderately steep areas, and did not include elevation as a predictor variable. Our results highlight the importance of evaluating den selection in terms of both use and availability of den characteristics. ?? 2007 American Society of Mammalogists.

    Full Text Available Statine, potente Inhibitoren der HMG-CoA-Reduktase, werden erfolgreich zur Senkung der Cholesterinblutspiegel eingesetzt. In den letzten Jahren sind jedoch zahlreiche andere Wirkungen der Statine aufgedeckt worden, die möglicherweise für den Knochenstoffwechsel von Bedeutung sind: In vitro konnten faszinierende knochenanabole Wirkungen der Statine bewiesen werden. Welche molekularen Mechanismen für diese Beobachtungen genau verantwortlich sind, ist nach wie vor unklar. Auch konnten in anderen In-vitro-Studien, Tiermodellen und klinischen Studien diese eindrucksvollen Resultate nicht immer bestätigt werden. Das vorliegende Bild der Statine im Knochenstoffwechsel ist uneinheitlich. Viele Fragen bleiben offen.

  7. Vitamin A absorption

    International Nuclear Information System (INIS)

    Baker, S.J.

    1976-01-01

    Investigation of the absorption of vitamin A and related substances is complicated by the multiplicity of forms in which they occur in the diet and by the possibility that they may be subject to different mechanisms of absorption. Present knowledge of these mechanisms is inadequate, especially in the case of carotenoids. Numerous tests of absorption have been developed. The most common has been the biochemical measurement of the rise in plasma vitamin A after an oral dose of retinol or retinyl ester, but standardization is inadequate. Radioisotope tests based upon assay of serum or faecal activity following oral administration of tritiated vitamin A derivaties hold considerable promise, but again standardization is inadequate. From investigations hitherto performed it is known that absorption of vitamin A is influenced by several diseases, although as yet the consistency of results and the correlation with other tests of intestinal function have often been poor. However, the test of vitamin A absorption is nevertheless of clinical importance as a specialized measure of intestinal function. (author)

  11. Vitamins for enhancing plant resistance.

    Science.gov (United States)

    Boubakri, Hatem; Gargouri, Mahmoud; Mliki, Ahmed; Brini, Faiçal; Chong, Julie; Jbara, Moez

    2016-09-01

    This paper provides an overview on vitamins with inducing activities in plants, the molecular and cellular mechanisms implicated, and the hormonal signalling-network regulating this process. Moreover, it reports how vitamins might be part of the molecular events linked to induced resistance by the conventional elicitors. Induced resistance (IR), exploiting the plant innate-defense system is a sustainable strategy for plant disease control. In the last decade, vitamins have been proven to act as inducers of disease resistance, and these findings have received an important attention owing to their safety and cost effectiveness. Vitamins, including thiamine (TH, vitamin B1), riboflavin (RF, vitamin B2), menadione sodium bisulfite (MSB, vitamin K3), Para-aminobenzoic acid (PABA, vitamin Bx), and folic acid (FA, vitamin B9) provided an efficient protection against a wide range of pathogens through the modulation of specific host-defense facets. However, other vitamins, such as ascorbic acid (AA, vitamin C) and tocopherols (vitamin E), have been shown to be a part of the molecular mechanisms associated to IR. The present review is the first to summarize what vitamins are acting as inducers of disease resistance in plants and how could they be modulated by the conventional elicitors. Thus, this report provides an overview on the protective abilities of vitamins and the molecular and cellular mechanisms underlying their activities. Moreover, it describes the hormonal-signalling network regulating vitamin-signal transduction during IR. Finally, a biochemical model describing how vitamins are involved in the establishment of IR process is discussed.

  15. Vitamin D and bone health

    International Nuclear Information System (INIS)

    Holick, M.F.

    1996-01-01

    Vitamin D plays an essential role in maintaining a healthy mineralized skeleton for most land vertebrates including humans. Sunlight causes the photoproduction of vitamin D3 in the skin. Once formed, vitamin D3 is metabolized sequentially in the liver and kidney to 1,25-dihydroxyvitamin D. The major biological function of 1,25-dihydroxyvitamin D is to keep the serum calcium and phosphorus concentrations within the normal range to maintain essential cellular functions and to promote mineralization of the skeleton. Most foods do not contain any vitamin D. Foods fortified with vitamin D have a variable amount present and cannot be depended on as a sole source of vitamin D nutrition. Exposure to sunlight provides most humans with their vitamin D requirement. Aging, sunscreen use and the change in the zenith angle of the sun can dramatically affect the cutaneous production of vitamin D3. Vitamin D insufficiency and vitamin D deficiency is now being recognized as a major cause of metabolic bone disease in the elderly. Vitamin D deficiency not only causes osteomalacia but can exacerbate osteoporosis. It is generally accepted that an increase in calcium intake to 1000-1500 mg/d along with an adequate source of vitamin D of at least 400 IU/d is important for maintaining good bone health

  1. Extraskeletal effects of vitamin D

    Directory of Open Access Journals (Sweden)

    Maurizio Rossini

    2011-04-01

    Full Text Available In the last years we observed an increasing number of publications about the vitamin D, due to its recognised therapeutic actions and to the widespread hypovitaminosis D. In addition to the well known skeletal benefits, vitamin D can have multiple effects on other tissues.Muscular apparatus: hypovitaminosis D is associated with myopathy, sarcopenia, muscular strength reduction and increased risk of falls. The vitamin D supplementation increases the muscle functionality indexes. Cardiovascular system: low levels of vitamin D are related to increased levels of cardiovascular risk factors, heart failure, stroke, and cardiovascular mortality, while a good vitamin D status is associated with a decreased incidence of cardiovascular diseases. Diabetes and metabolic syndrome: a good vitamin D status is related to a decreased incidence of type 2 diabetes and metabolic syndrome; a vitamin D supplementation in the early childhood reduces (nearly 30% the risk of having type 1 diabetes. Cancer: vitamin D deficit is associated with breast, colorectal cancer and melanoma relapses. Low and high levels of 25-hydroxy-vitamin D (25(OHD are related to a higher neoplastic mortality. Infectious diseases: hypovitaminosis D is associated with higher incidence of upper respiratory tract infections and worse interferon response in chronic hepatitis C. Vitamin D supplementation decreases the risk of having type A influence. Rheumatic diseases: in rheumatoid arthritis low serum levels of vitamin D metabolites are related to a higher disease activity, while a good vitamin D status is associated with a higher probability of remission or response to therapy and a lower degree of disability. Neurologic diseases: associations between vitamin D deficit and risk of multiple sclerosis, depression, cognitive deficits, and Parkinson’s disease have been reported.There is evidence of the extraskeletal effects of vitamin D, but most derive from observational studies: clinical trials

    1960-11-01

    Full Text Available Zur Klaerung der Frage, ob der Begriff "Kinoplasma" fuer gewisse, von MERTON (1924,1926, 1930 beobachtete Bildungen an den reifenden Spermiden von pulmonaten Mollusken oder fuer Bestandteile des Cytoplasmas im Sinne von STRASBURGER und SCARTH zu verwenden ist, werden in der vorliegenden Mitteilung die Vorgaenge bei der Spermiohistogenese von Australorbis glabratus olivaceus untersucht. Es ergibt sich: 1. Das von MERTON bezeichnete "Kinoplasma" existiert nicht als solches, es handelt sich bei den von ihm dargestellten Protoplasmabildungen um kugelige, von den Spermiden abgeschnuerte Restkoerper nicht verwendeten Baumaterials, bestehend aus Protoplasma und einigen Mitochondrien. Sie werden von den Naehr- oder Bazalzellen phagozytiert. Der Ausdruck "Kinoplasma" kann nur fuer die submikroskopischen, geformten, faedigen Elemente des Cytoplasmas reserviert bleiben, die den geradlinigen Fall der uebrigen nicht geformten Komponenten bremst oder ablenkt; damit muss das Kinoplasma aber aus dem Begriff des Cytoplasmas herausgenommen werden, da es, wenn auch vermutlich reversibel, eine Differenzierung darstellt. 2. Der Spermienfaden wird von den Centriolen (Axialfilament und den Mitochondrien (zwei peripher gelegene Spiralfilamente, sowie einem Plasmamantel gebildet. 3. Nach Beendigung des Auswachsens der Spermiengeissel, die zu diesem Zeitpunkt nur aus dem Achsenfaden und dem Protoplasmazylinder besteht, setzt sich eine Protoplasmamasse vom Kopf in Richtung zum Geisselende in Bewegung. Sie fuehrt den Golgi-Koerper und sehr viele Mitochondrien mit sich. Aus diesen entwickeln sich Fibrillen, die sich zu den beiden Spiralfilamenten zusammenfuegen. Diese Masse entspricht der von MERTON in seiner Theorie als Kinoplasma bezeichneten Komponente. 4. Die Bewegung dieses Protoplasmateils wird auf den Schub zurueckgefuehrt, den die sich bildenden Fibrillen auf die Mitochondrien ausueben. 5. Die Rueckwaertsbewegung dieses Protoplasmakoerpers beruht wahrscheinlich auf

    Stelios Katsanevakis

    2004-03-01

    Full Text Available To avoid predation, octopuses select and actively modify shelters (also called dens in the substratum, where they remain most of the time, especially during daylight hours. The main questions that this study deals with are: Is den availability a significant constraint for the distribution of Octopus vulgaris on soft sediment? What kind of dens does O. vulgaris use on soft sediment and what factors affect the selection of one type instead of another? With population density measurements by SCUBA diving and enrichment experiments with artificial dens, we concluded that the availability of solid materials necessary for den construction is a limiting factor for the distribution of O. vulgaris on soft sediment. O. vulgaris used four different types of den on soft sediment: well (a vertical hole in the sediment, rock/stone (the octopus uses a rock or a large stone to dig a cavity under it, shell (an empty shell is used, human origin (a solid material of human origin is used. The relative proportion of the four types of den in the areas studied was: 38.7% human origin, 29.7% well, 21.5% rock/stone, 2.9% shell. Also, 7.3% of the octopuses were found outside their den. The main types of den were found in different relative proportions in relation to the depth, the distance from shore, the octopus size and the granulometry of the sediment.

  6. Vitamin d and physical performance.

    Science.gov (United States)

    Moran, Daniel S; McClung, James P; Kohen, Tal; Lieberman, Harris R

    2013-07-01

    Vitamin D is an essential nutrient obtained from the diet and exposure to sunlight. Roles for vitamin D have been established in the function of the cardiovascular, immune, and musculoskeletal systems. An electronic database search was conducted using EMBASE (1967 to August 2012), MEDLINE (1966 to August 2012), SPORTDiscus™ (1975 to August 2012), and the Scientific Electronic Library Online (SciELO) (1998 to August 2012) with no limits of language of publication. Articles that described vitamin D and performance were considered eligible for this review. Recent studies suggest that vitamin D maintains physical performance in athletes and other active populations, e.g., maximal oxygen consumption may be related to vitamin D status. Poor vitamin D status affects muscle strength, and vitamin D may participate in protein synthesis through the actions of the vitamin D receptor in muscle tissue. Vitamin D may protect against overuse injuries, such as stress fracture, through its well-documented role in calcium metabolism. The objective of this manuscript is to review recent evidence regarding the importance of vitamin D for maintaining physical performance, and includes specific examples of how vitamin D supports the cardiovascular, immune, and musculoskeletal systems.

  7. Vitamin D and Heart Failure.

    Science.gov (United States)

    Marshall Brinkley, D; Ali, Omair M; Zalawadiya, Sandip K; Wang, Thomas J

    2017-10-01

    Vitamin D is principally known for its role in calcium homeostasis, but preclinical studies implicate multiple pathways through which vitamin D may affect cardiovascular function and influence risk for heart failure. Many adults with cardiovascular disease have low vitamin D status, making it a potential therapeutic target. We review the rationale and potential role of vitamin D supplementation in the prevention and treatment of chronic heart failure. Substantial observational evidence has associated low vitamin D status with the risk of heart failure, ventricular remodeling, and clinical outcomes in heart failure, including mortality. However, trials assessing the influence of vitamin D supplementation on surrogate markers and clinical outcomes in heart failure have generally been small and inconclusive. There are insufficient data to recommend routine assessment or supplementation of vitamin D for the prevention or treatment of chronic heart failure. Prospective trials powered for clinical outcomes are warranted.

  8. Synthesis of B6 vitamin

    Directory of Open Access Journals (Sweden)

    Vučijak Nevena Ž.

    2009-01-01

    Full Text Available The importance of vitamin B6 has been known since its discovery in the 1940's. Chemical tests, elestrometric titration determinations, and absorption spectrum studies showed that this vitamin exists in three major chemical forms: pyridoxine (an alcohol, pyridoxal (an aldehyde, and pyridoxamine (a primary amine. Vitamin B6 is needed for more than 100 enzymes involved in protein metabolism, and it is assumed that this vitamin is cofactor of metabolic processes more important than any other substance. A deficiency of vitamin B6 in the human diet leads to severe disorders. Vitamin B6 is necessary for the proper function of the immune and nervous system, and helps the body convert protein to energy. This paper describes the history, properties and applications of vitamin B6, elucidation of chemical structure, and different procedures for synthesis of pyridoxine and pyridoxamine.

  9. Vitamin D and respiratory disorder

    Mahnaz Hushmand

    2015-09-01

    Full Text Available The active form of vitamin D is synthesized in some body organs following sun exposure and dietary intake. Vitamin D exhibits its major and critical effects not only through regulation of calcium and phosphate metabolism but also by influencing on respiratory and immune system. Serum concentrations of 25-hydroxyvitamin D below the optimum limit lead to vitamin D insufficiency or maybe deficiency. These inappropriate concentrations of vitamin D lead to different types of pulmonary diseases such as viral and bacterial respiratory infection, asthma, chronic obstructive pulmonary disease, and cancer. In this review we described the association between vitamin D deficiency and severe therapy resistant asthma. We also reviewed the underlying molecular mechanism of vitamin D deficiency in children with severe- therapy resistant asthma. Based on current information, future clinical trial are needed to study the role of vitamin D supplementation on different groups of patients with severe asthma including infants, children of school age, and ethnic minorities.

    2007-01-01

    Full Text Available Vitamin D, a fat-soluble prohormone is synthesized in response to sunlight. Experimental evidence suggests that vitamin D may reduce the risk of cancer through regulation of cellular proliferation and differentiation as well as inhibition of angiogenesis. These anticancer properties have been attributed primarily to 1,25-dihydroxyvitamin D [1,25(OH 2 D] (calcitriol, the hormonal form of vitamin D. Extensive research has shown that cells, including cancer cells, express specific receptors (VDR for 1,25-dihydroxyvitamin D. When bound to the VDR, 1,25-dihydroxyvitamin D regulates> 60 genes that exert prodifferentiating, antiproliferative and antimetastatic effects on cells, including effects on cell cycle. The amount of exposure to the sun has been found to correlate inversely with cancer mortality and survival in numerous epidemiological studies. An inverse relationship between solar ultraviolet-B (UV-B exposure and non-skin cancer mortality has long been reported. Several ecological studies suggest that sunlight may protect against prostate, colon, rectal, female breast and ovarian cancer, all diseases that contribute to a substantially higher proportion of cancer mortality in the western industrialized world. Some analytical studies also suggest a protective association between circulating vitamin D in blood, which is largely derived from sunlight, or dietary vitamin D. Paricalcitol (calcitriol analogue is as effective as 1,25-dihydroxyvitamin D in transactivating the prostatic VDR and in inhibiting the growth of prostate cancer cell lines and primary cultures of prostate cancer cells in vitro. Promising preclinical evaluations of calcitriol and analogues have appeared in prostate cancer animal models.

    2007-01-01

    I denne artikel diskuterer jeg Immanuel Kants videnskabssyn, som det tager sig ud i Kritik af dømmekraften. Udgangspunktet er erkendelsesteorien og i særdeleshed den såkaldte skemateori. For Kant findes der rene videnskaber og empiriske videnskaber. De rene videnskabers begreber er karakteriseret...... instrumentalisme, der hersker. Der er visse subjektive principper og maximer, som er mere ’naturlige’ og ’rigtige’ end andre. Kants typiske eksempler herpå er ideen om fuldstændig enhed af den videnskabelige erkendelse og ideen om teleologi i naturen – at intet i naturen er tilfældigt, og at alt har et formål....... Artiklen afsluttes ved at perspektivere og sammenstille Kants videnskabsfilosofi med Thomas Kuhns nutidige videnskabsteori. Jeg argumenterer for, at Kants og Kuhns teorier har fundamentale elementer og strukturer til fælles, og at de vigtigste fornuftsmæssige ideer og principper hos Kant går igen i Kuhns...

    Full Text Available Dieser Beitrag soll aufzeigen, dass eine chthonische und eschatologische Dimension der dionysischen Göttlichkeit in verschiedenen Riten und Kulten des Gottes nachgewiesen werden kann und dabei keinesfalls mysterienexklusiv ist. Dazu soll der archäologische Befund, der Dionysos mit dem Jenseits und eschatologischen Ho nungen in Verbindung bringt, vorgestellt und untersucht werden. Darauf aufbauend soll belegt werden, dass diese jenseitige Dimension sich sowohl in Riten mit privatem Kern, hier am Beispiel der Oreibasia, als auch in Kultfeiern des ö entlichen Festkanons, wie den Anthesterien, zeigt. Abschließend soll dann Dionysos‘ Funktion in den eleusinischen Mysterien untersucht werden. This paper aims to show that a chthonic and eschatological dimension of dionysiac divinity can be found in various rites and cults of the god and that this is not exclusive for the mysteries. Recent archaeological evidence connecting Dionysos with the afterlife and eschatological expectations will be introduced and analyzed. is dimension manifests itself in rites with a private intent (e.g. the Oreibasia as well as public celebrations of the festival calendar (e.g. the Anthesteria. An analysis of Dionysos’ function in the eleusinian mysteries concludes the overview.

    How micronutrients might influence risk of developing adenocarcinoma of the prostate has been the focus of a large body of research (especially regarding vitamins E, A, and D). Metabolomic profiling has the potential to discover molecular species relevant to prostate cancer etiology, early detection, and prevention, and may help elucidate the biologic mechanisms through which vitamins influence prostate cancer risk. Prostate cancer risk data related to vitamins E, A, and D and metabolomic profiling from clinical, cohort, and nested case-control studies, along with randomized controlled trials, are examined and summarized, along with recent metabolomic data of the vitamin phenotypes. Higher vitamin E serologic status is associated with lower prostate cancer risk, and vitamin E genetic variant data support this. By contrast, controlled vitamin E supplementation trials have had mixed results based on differing designs and dosages. Beta-carotene supplementation (in smokers) and higher circulating retinol and 25-hydroxy-vitamin D concentrations appear related to elevated prostate cancer risk. Our prospective metabolomic profiling of fasting serum collected 1-20 years prior to clinical diagnoses found reduced lipid and energy/TCA cycle metabolites, including inositol-1-phosphate, lysolipids, alpha-ketoglutarate, and citrate, significantly associated with lower risk of aggressive disease. Several active leads exist regarding the role of micronutrients and metabolites in prostate cancer carcinogenesis and risk. How vitamins D and A may adversely impact risk, and whether low-dose vitamin E supplementation remains a viable preventive approach, require further study.

  16. Vitamin D in Pain Management.

    Science.gov (United States)

    Helde-Frankling, Maria; Björkhem-Bergman, Linda

    2017-10-18

    Vitamin D is a hormone synthesized in the skin in the presence of sunlight. Like other hormones, vitamin D plays a role in a wide range of processes in the body. Here we review the possible role of vitamin D in nociceptive and inflammatory pain. In observational studies, low vitamin D levels have been associated with increased pain and higher opioid doses. Recent interventional studies have shown promising effects of vitamin D supplementation on cancer pain and muscular pain-but only in patients with insufficient levels of vitamin D when starting intervention. Possible mechanisms for vitamin D in pain management are the anti-inflammatory effects mediated by reduced cytokine and prostaglandin release and effects on T-cell responses. The recent finding of vitamin D-mediated inhibition of Prostaglandin E2 (PGE2) is especially interesting and exhibits a credible mechanistic explanation. Having reviewed current literature, we suggest that patients with deficient levels defined as 25-hydroxyvitamin D (25-OHD) levels 50 nmol/L probably have little benefit from supplementation. Our conclusion is that vitamin D may constitute a safe, simple and potentially beneficial way to reduce pain among patients with vitamin D deficiency, but that more randomized and placebo-controlled studies are needed before any firm conclusions can be drawn.

  17. Vitamin D in allergic disorders

    Directory of Open Access Journals (Sweden)

    2014-09-01

    Full Text Available Vitamin D is a factor that plays a significant role in calcium-phosphate balance. It has an effect on bone metabolism and also has modulator and anti-inflammatory activity. It is claimed that vitamin D inhibits immunological reactions with Th1 and Th17 lymphocytes. The influence of vitamin D on Th2 lymphocytes is not clear. The main effect of vitamin D is probably the activation of Treg lymphocytes. It was observed that vitamin D had a beneficial influence on diseases connected with excessive activation of Th1 lymphocytes, such as multiple sclerosis, rheumatoid arthritis, non-specific enteritis, diabetes type 1 or psoriasis. The role of vitamin D in allergic diseases, in which increased activation of Th2-dependent reactions are of great importance, is controversial. However, due to a wide range of vitamin D activity, this view seems to be simplified. A beneficial effect on the course of allergic diseases was observed in up-to-date studies although the role of vitamin D in their pathogenesis has not been explained yet. On the basis of recent studies and well-known mechanisms of vitamin D activity on particular elements of the immunological system, the influence of vitamin D on the course of chosen allergic diseases, such as allergic asthma, atopic dermatitis and allergic rhinitis was presented considering the possibility of contribution of allergen-specific immunotherapy.

    2003-01-01

    Activity of Swift Foxes (Vulpes velox) at den sites was studied in northwestern Texas during pup rearing seasons in 2000 and 2001 to determine role of males in parental care. Twenty-four percent of radio-collared females with a potential to breed successfully raised pups to eight weeks of age. We intensively monitored presence and absence of male and female Swift Foxes at two den sites each year. Females were present >2.6 times more at den sites than males during the pup rearing season. Female and male Swift Foxes largely stayed at dens during diurnal hours and were active away from dens during nocturnal and crepuscular hours. Females and males spent 12.4% and 3.0% more time at dens before pups emerged, than after pups emerged, respectively. Following depredation of one male parent, the female spent 29% less time at the den site. Decrease in time spent at the den by the female following loss of her mate suggested that loss of one parent might severely impact recruitment of Swift Foxes. Our observations indicated that intense Coyote (Canis latrans) depredation may severely impact pup-rearing success as well as the parental care within Swift Fox family groups.

  7. Cardiovascular Diseases and Fat Soluble Vitamins: Vitamin D and Vitamin K.

    Science.gov (United States)

    Tsugawa, Naoko

    2015-01-01

    Recently, the associations between insufficiency of fat soluble vitamins and cardiovascular diseases (CVDs) have been reported. Vitamin D affects the cardiovascular system via several pathways, such as suppression of parathyroid hormone, the renin- angiotensin-aldosterone system and vascular endothelial growth and the immune system. Cross-sectional and longitudinal studies have shown the association between the concentration of serum 25-hydroxyvitamin D (25OHD), which is a vitamin D metabolite indicating nutritional vitamin D status, and hypertension, myocardial infarction, heart failure and CVD mortality. On the other hand, the association between vitamin K status and CVDs, especially vascular calcification, has been also reported. Cross-sectional and cohort studies show that high vitamin K status is associated with reduced coronary artery calcification, CVDs and mortality risk. Epidemiological and basic studies indicate that vitamin K possesses a benefit in the prevention of the progression of coronary artery calcification via activation of matrix-gla protein (MGP). While these data in epidemiological and basic studies suggest the protective role of vitamin D and K in CVDs, the benefits of supplementation of both vitamins have not been validated in randomized controlled trials. Further basic and interventional studies are needed to confirm the benefit of both vitamins in protection against CVDs.

    Muscle weakness is a hallmark of severe vitamin D deficiency, but the effect of milder vitamin D deficiency or insufficiency on muscle mass and performance and risk of falling is uncertain. In this presentation, I review the evidence that vitamin D influences muscle mass and performance, balance, and risk of falling in older adults. Special consideration is given to the impact of both the starting 25-hydroxyvitamin D [25(OH)D] level and the dose administered on the clinical response to supplemental vitamin D in older men and women. Based on available evidence, older adults with serum 25(OH)D levels vitamin D dose range of 800-1000 IU per day has been effective in many studies; lower doses have generally been ineffective and several doses above this range have increased the risk of falls. In conclusion, older adults with serum 25(OH)D levels vitamin D. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Signaling through the vitamin D receptor has been shown to be biologically active and important in a number of preclinical studies in prostate and other cancers. Epidemiologic data also indicate that vitamin D signaling may be important in the cause and prognosis of prostate and other cancers. These data indicate that perturbation of vitamin D signaling may be a target for the prevention and treatment of prostate cancer. Large studies of vitamin D supplementation will be required to determine whether these observations can be translated into prevention strategies. This paper reviews the available data in the use of vitamin D compounds in the treatment of prostate cancer. Clinical data are limited which support the use of vitamin D compounds in the management of men with prostate cancer. However, clinical trials guided by existing preclinical data are limited.

Results indicate that this rodent uses holes in the ground or in fallen trees as sleeping dens. Each of these sleeping dens had two or more orifices and an internal cavity for the "diurnal sleep”. Typically, one orifice was for common use and the rest for the circumstantial escape. According to their form, their localization in the ground, and the number and location of orifices, sleeping dens were classified into four types, of which type A was the most common. The results also indicate a greater concentration of sleeping dens in temporary flooded gallery forest.

  1. Radioresponse of mice testes with or without vitamin-E

    2001-01-01

    Vitamins have generated a great deal of interest in recent years for a wide range of protective effects in biological systems. The present study is an attempt to assess the prophylactic use of Vitamin-E against radiation induced changes in the testicular cell counts of Swiss albino mice after exposure to low dose of gamma rays. Quantitative changes in different type of testicular cells of adult Swiss albino mice exposed to 1.6 Gy gamma rays after 7 days prior treatment of vitamin-E (as α-tocopherol), once a day, were studied. The results were compared with those obtained from animals irradiated with the same dose of gamma rays in the absence of Vitamin-E. It was found that the number of different cell counts declined in the testes after irradiation. A continuous depletion was found in the frequency of different spermatogonia types and primary spermatocytes from 6 h to 5 d after irradiation both with control and experimental groups. The counts of such testicular components started elevating from day 10, but remained below normal till 20 days post-irradiation. A progressive decline in the counts of spermatids was also observed from 6 h to the last autopsy interval. However, the experimental values were significantly higher than their corresponding controls at days 10 and 20 post-irradiation intervals. It appears that the higher surviving germ cells population and lesser testicular degeneration in Vitamin-E treated animals is the result of high degree of protection provided by Vitamin-E to the germ cells, which continue to retain their proliferative activities.

    2006-01-01

    Simultaneous Determination of Vitamins.--Klejdus et al. described a simultaneous determination of 10 water- and 10 fat-soluble vitamins in pharmaceutical preparations by liquid chromatography-diode-array detection (LC-DAD). A combined isocratic and linear gradient allowed separation of vitamins in 3 distinct groups: polar, low-polar, and nonpolar. The method was applied to pharmaceutical preparations, fortified powdered drinks, and food samples, for which results were in good agreement with values claimed. Heudi et al. described a separation of 9 water-soluble vitamins by LC-UV. The method was applied for the quantification of vitamins in polyvitaminated premixes used for the fortification of infant nutrition products. The repeatability of the method was evaluated at different concentration levels and coefficients of variation were based on, for example, LC. Koontz et al. showed results of total folate concentrations measured by microbiological assay in a variety of foods. Samples were submitted in a routine manner to experienced laboratories that regularly perform folate analysis fee-for-service basis in the United States. Each laboratory reported the use of a microbiological method similar to the AOAC Official Method for the determination of folic acid. Striking was, the use of 3 different pH extraction conditions by 4 laboratories. Only one laboratory reported using a tri-enzyme extraction. Results were evaluated. Results for folic acid fortified foods had considerably lower between-laboratory variation, 9-11%, versus >45% for other foods. Mean total folate ranged from 14 to 279 microg/100 g for a mixed vegetable reference material, from 5 to 70 microg/100 g for strawberries, and from 28 to 81 microg/100 g for wholemeal flour. One should realize a large variation in results, which might be caused by slight modifications in the microbiological analysis of total folate in foods or the analysis in various (unfortified) food matrixes. Furthermore, optimal

  5. Vitamins and bone health: beyond calcium and vitamin D.

    Science.gov (United States)

    Ahmadieh, Hala; Arabi, Asma

    2011-10-01

    Osteoporosis is a major health disorder associated with an increased risk of fracture. Nutrition is among the modifiable factors that influence the risk of osteoporosis and fracture. Calcium and vitamin D play important roles in improving bone mineral density and reducing the risk of fracture. Other vitamins appear to play a role in bone health as well. In this review, the findings of studies that related the intake and/or the status of vitamins other than vitamin D to bone health in animals and humans are summarized. Studies of vitamin A showed inconsistent results. Excessive, as well as insufficient, levels of retinol intake may be associated with compromised bone health. Deficiencies in vitamin B, along with the consequent elevated homocysteine level, are associated with bone loss, decreased bone strength, and increased risk of fracture. Deficiencies in vitamins C, E, and K are also associated with compromised bone health; this effect may be modified by smoking, estrogen use or hormonal therapy after menopause, calcium intake, and vitamin D. These findings highlight the importance of adequate nutrition in preserving bone mass and reducing the risk of osteoporosis and fractures. © 2011 International Life Sciences Institute.

    We examined eight summer dens (used only in summer) and seven hibernacula (occupied both in winter and summer) of the snake Pituophis melanoleucus in the New Jersey Pine Barrens, comparing above ground characteristics of hibernacula and summer dens with characteristics at nearby random points. Temperatures at the soil surface and at 10 cm depth were significantly warmer, and there was less leaf cover around the random points compared to the entrances of the hibernacula and summer dens. Hibernacula had significantly more vegetation cover within 5 m, more leaf cover over the burrow entrance, and were closer to trees than were summer dens. Most hibernacula and summer dens were beside old fallen logs (73%), the entrance tunnels following decaying roots into the soil. Excavation of the hibernacula and summer dens indicated that most hibernacula appeared to be dug by the snakes and had an average of eight side chambers and 642 cm of tunnels, compared to less than one side chamber and 122 cm of tunnels for summer dens. Except for hatchlings, most snakes in hibernacula were located in individual chambers off the main tunnel; all snakes were at depths of 50-111 cm (X̄ = 79 cm). Pine snakes may select optimum hibernation sites which reduce winter mortality.

    Full Text Available The majority of the vitamin D in our body is produced by cutaneous synthesis in response to sunlight. As more and more people live in cities and spend the bulk of their time indoors, it can be difficult to get sufficient sun exposure for adequate cutaneous production of vitamin D. Therefore, vitamin D insufficiency has become a very common health problem worldwide. The Korea National Health and Nutrition Examination Survey IV 2008 showed that the prevalence of vitamin D insufficiency, defined as a serum 25-hydroxyvitamin D [25(OHD] level below 50 nmol/L, was 47.3% in males and 64.5% in females. Only 13.2% of males and 6.7% of females had a serum 25(OHD level of greater than 75 nmol/L. In Korea, vitamin D insufficiency was more prevalent in young adults than in elderly people, likely due to the indoor lifestyle of younger people. Compared with the United States and Canada, Korea has a lower mean 25(OHD level and a higher prevalence of vitamin D insufficiency. To improve the vitamin D status of the Korean population, more aggressive policies on food fortification and vitamin D supplementation are needed.

    Vitamin D has been identified as an important factor in healthy aging and is receiving growing attention in clinical research. Vitamin D is a fat-soluble molecule, which is synthesized by hepatic and renal or extra-renal hydroxylation into the active hormone 1,25-dihydroxyvitamin D (1,25(OH)2D).

    Vitamin D insufficiency/deficiency has been worldwide reported in all age groups in recent years. It has been considered a Public Health matter since decreased levels of vitamin D has been related to several chronic diseases, as type 2 diabetes mellitus (T2DM), obesity and hypertension. Glucose intolerance and insulin secretion has been observed during vitamin D deficiency, both in animals and humans resulting in T2DM. The supposed mechanism underlying these findings is presence of vitamin D receptor in several tissues and cells, including pancreatic beta-cells, adipocyte and muscle cells. In obese individuals, the impaired vitamin D endocrine system, characterized by high levels of PTH and 1,25(OH)(2)D(3) could induce a negative feedback for the hepatic synthesis of 25(OH)D and also contribute to a higher intracellular calcium, which in turn secrete less insulin and deteriorate insulin sensitivity. In hypertension, vitamin D could act on renin-angiotensin system and also in vascular function. Administration of 1,25(OH)(2)D(3) could decreases renin gene expression and inhibit vascular smooth muscle cell proliferation. However, prospective and intervention human studies that clearly demonstrates the benefits of vitamin D status adequacy in the prevention and treatment of endocrine metabolic diseases are lacking. Further research still necessary to assure the maximum benefit of vitamin D in such situations.

    2013-01-01

    Vitamin K has been purported to play an important role in bone health. It is required for the gamma-carboxylation of osteocalcin (the most abundant noncollagenous protein in bone), making osteocalcin functional. There are 2 main forms (vitamin K1 and vitamin K2), and they come from different sources and have different biological activities. Epidemiologic studies suggest a diet high in vitamin K is associated with a lower risk of hip fractures in aging men and women. However, randomized controlled trials of vitamin K1 or K2 supplementation in white populations did not increase bone mineral density at major skeletal sites. Supplementation with vitamin K1 and K2 may reduce the risk of fractures, but the trials that examined fractures as an outcome have methodological limitations. Large well-designed trials are needed to compare the efficacies of vitamin K1 and K2 on fractures. We conclude that currently there is not enough evidence to recommend the routine use of vitamin K supplements for the prevention of osteoporosis and fractures in postmenopausal women.

    2017-05-01

    We review recent findings on the involvement of vitamin D in skeletal muscle trophicity. Vitamin D deficiencies are associated with reduced muscle mass and strength, and its supplementation seems effective to improve these parameters in vitamin D-deficient study participants. Latest investigations have also evidenced that vitamin D is essential in muscle development and repair. In particular, it modulates skeletal muscle cell proliferation and differentiation. However, discrepancies still exist about an enhancement or a decrease of muscle proliferation and differentiation by the vitamin D. Recently, it has been demonstrated that vitamin D influences skeletal muscle cell metabolism as it seems to regulate protein synthesis and mitochondrial function. Finally, apart from its genomic and nongenomic effects, recent investigations have demonstrated a genetic contribution of vitamin D to muscle functioning. Recent studies support the importance of vitamin D in muscle health, and the impact of its deficiency in regard to muscle mass and function. These 'trophic' properties are of particular importance for some specific populations such as elderly persons and athletes, and in situations of loss of muscle mass or function, particularly in the context of chronic diseases.

  2. Vitamin D deficiency and stroke

    Directory of Open Access Journals (Sweden)

    2012-12-01

    Full Text Available Vitamin D comprises a group of fat-soluble pro-hormones, obtained from sun exposure, food, and supplements, and it must undergo two hydroxylation reactions to be activated in the body. Several studies have shown the role of vitamin D in mineral metabolism regulation, especially calcium, phosphorus, and bone metabolism. Some factors such as inadequate vitamin intake and liver or kidney disorders can lead to vitamin D deficiency. Furthermore, vitamin D malnutrition may also be linked to susceptibility to chronic diseases such as heart failure, peripheral artery disease, high blood pressure, cognitive impairment including foggy brain and memory loss, and autoimmune diseases including diabetes type I. Recent research has revealed that low levels of vitamin D increase the risk of cardiovascular-related morbidity (Sato et al., 2004 and mortality (Pilz et al., 2008. Also, hypertension contributes to a reduction in bone mineral density and increase in the incidence of stroke and death. This article reviews the function and physiology of vitamin D and examines the effects of vitamin D deficiency on susceptibility to stroke, as a cardiovascular event, and its morbidity and subsequent mortality.

    Full Text Available The review discusses the effect of vitamin D on the tolerogenic modulation of an immune response, its relationship to cells of the monocyte-macrophage series, including dendritic cells, monocytes, and macrophages, in the context of the impact of the expression of anti-inflammatory proinflammatory cytokines in some autoimmune diseases (rheumatoid arthritis, systemic scleroderma, multiple sclerosis, type 1 diabetes mellitus, systemic lupus erythematosus, and Crohn`s disease. It discusses the role of vitamin D in the development of innate and adaptive immunity. Despite some conflicting evidence, the immune regulatory function of vitamin D is generally directed toward inhibition of the components of innate and acquired immunity, which are responsible for the induction of autoimmune reactions; in this connection there are a growing number of publications devoted to the issues of vitamin D supplementation in patients with autoimmune diseases, the preventive effect of vitamin D intake on the risk of an abnormality and that of therapeutic doses of the vitamin on its course. The maintenance of the threshold value for serum 25(OHD3 at least 30 ng/ml, which is achieved by the intake of about 2000 IU of vitamin D, is shown to be required for its immune regulatory function. The data given raise the question as to whether it is necessity to revise the Russian recommended daily dietary allowances for vitamin D through its infant food fortification.

    Vitamin D and calcium deficiency has a higher incidence in the orthopedic-trauma surgery patient population than generally supposed. In the long term this can result in osteomalacia, a form of altered bone mineralization in adults, in which the cartilaginous, non-calcified osteoid does not mature to hard bone. The current value of vitamin D and its importance for bones and other body cells are demonstrated. The causes of vitamin D deficiency are insufficient sunlight exposure, a lack of vitamin D3 and calcium, malabsorption, and rare alterations of VDR signaling and phosphate metabolism. The main symptoms are bone pain, fatigue fractures, muscular cramps, muscle pain, and gait disorders, with an increased incidence of falls in the elderly. Osteopathies induced by pharmaceuticals, tumors, rheumatism or osteoporosis have to be considered as the main differential diagnoses. In addition to the recording of symptoms and medical imaging, the diagnosis of osteomalacia should be ensured by laboratory parameters. Adequate treatment consists of the high-dose intake of vitamin D3 and the replacement of phosphate if deficient. Vitamin D is one of the important hormone-like vitamins and is required in all human cells. Deficiency of vitamin D has far-reaching consequences not only for bone, but also for other organ systems.

    2014-10-01

    In recent years has been a growing interest by vitamin D, not only for its important role in the bone mineral metabolism, but also by the extra-osseous effects. Most of the scientific societies consider that deposits are sufficient if the serum concentration of 25-OH vitamin D is above 30ng/ml and are considered deficient if levels are below 20ng/ml. The majority of studies found that supplements of calcium plus vitamin D have a positive effect in reducing the risk of fracture and the risk of falls in the elderly, although several specifies that doses should be 700-1.000 IU daily. The treatment of the deficit can be performed with vitamin D2, D3 as well as calcidiol or the active metabolite calcitriol. In certain pathologies also selective vitamin D receptor activators can be used. Copyright © 2014 Elsevier España, S.L. All rights reserved.

  6. Effect of irradiation on vitamins

    International Nuclear Information System (INIS)

    1994-01-01

    Food irradiation is a physical process involving treatment of food with ionising radiation. Its main uses are reduction in spoilage and pathogenic organisms, inhibition of ripening and sprouting processes, and insect disinfestation. Chemical changes in the treated foods are small, and expert committees have concluded that they carry no special nutritional problems. Some vitamins are sensitive to irradiative degradation, however, and opponents of the process have claimed that extensive destruction will occur. Irradiation doses will, however, be limited by organoleptic changes, and maximum levels are being introduced into legislation for specific foods. Examination of the published literature shows that vitamins C and B 1 are the most sensitive water-soluble vitamins, and that E and A are the most sensitive fat-soluble vitamins. Vitamin losses on irradiation of permitted foods in western countries will not be of nutritional importance. (Author)

    Full Text Available Dens in dente, also known as dens invaginatus, dilated composite odontoma, or deep foramen caecum, is a developmental malformation that usually affects maxillary incisor teeth, particularly lateral incisors. It may occur in teeth anywhere within the jaws, other locations are comparatively rare. It can occur within both the crown and the root, although crown invaginations are more common. The use of cone beam computed tomography (CBCT is very helpful in endodontic diagnosis of complex anatomic variations. In this case we demonstrate the use of CBCT in the evaluation and endodontic management of a Type III dens in dente (Oehler′s Type III.

    Objective: To check the Vitamin D levels in patients diagnosed as fibromyagia in our population. Methods: Study was done at Medical OPD of Civil Hospital Karachi, from January to March 2009. Female patients diagnosed as Fibromyalgia according to American College of Rheumatology (ACR) criteria and exclusion of systemic illness on examination, and normal reports of blood CP, ESR, serum calcium, phosphate and Alkaline Phosphatase, were asked to get Vitamin D levels in their serum. Vitamin D deficiency is defined as 30 ng/ml. Result: Forty female patients were included in the study. The mean age was 37.65 +- 11.5 years. Mean Vitamin D level was 17.41 +- 5.497 ng/ml. Thirty two (80%) of patients had Vitamin D deficiency, mean levels of 15.855 +- 4.918 ng/ml and 8(20%) had Vitamin D insufficiency, mean levels of 23.64 +- 2.39 ng/ml. Patients with vitamin D deficiency and age less than 45 years were 22 (68.75%), had mean vitamin D level 16.87 +- 4.48 ng/ml whereas in age ranging from 46-75 years were 10 (31.25%) had mean vitamin D level 16.09 +- 6.45 ng/ml. Conclusion: Vitamin D deficiency is frequently seen in patients diagnosed as fibromyalgia and nonspecific musculoskeletal pain in our population. Although the sample size of the study is small, but the figures are so alarming that it is an eye opener towards the need of a population based study, including normal population as well as those presenting with musculoskeletal pain.

  13. Vitamin C and Immune Function

    Directory of Open Access Journals (Sweden)

    Anitra C. Carr

    2017-11-01

    Full Text Available Vitamin C is an essential micronutrient for humans, with pleiotropic functions related to its ability to donate electrons. It is a potent antioxidant and a cofactor for a family of biosynthetic and gene regulatory enzymes. Vitamin C contributes to immune defense by supporting various cellular functions of both the innate and adaptive immune system. Vitamin C supports epithelial barrier function against pathogens and promotes the oxidant scavenging activity of the skin, thereby potentially protecting against environmental oxidative stress. Vitamin C accumulates in phagocytic cells, such as neutrophils, and can enhance chemotaxis, phagocytosis, generation of reactive oxygen species, and ultimately microbial killing. It is also needed for apoptosis and clearance of the spent neutrophils from sites of infection by macrophages, thereby decreasing necrosis/NETosis and potential tissue damage. The role of vitamin C in lymphocytes is less clear, but it has been shown to enhance differentiation and proliferation of B- and T-cells, likely due to its gene regulating effects. Vitamin C deficiency results in impaired immunity and higher susceptibility to infections. In turn, infections significantly impact on vitamin C levels due to enhanced inflammation and metabolic requirements. Furthermore, supplementation with vitamin C appears to be able to both prevent and treat respiratory and systemic infections. Prophylactic prevention of infection requires dietary vitamin C intakes that provide at least adequate, if not saturating plasma levels (i.e., 100–200 mg/day, which optimize cell and tissue levels. In contrast, treatment of established infections requires significantly higher (gram doses of the vitamin to compensate for the increased inflammatory response and metabolic demand.

    The extrinsic sources for erosion-causing acids are primarily acidic beverages and foodstuffs. Effervescent tablets also contain organic acids (e.g. citric, tartaric, malic) in order to form carbon dioxide by contact with water – with the help of the carbonate salts of the tablets. To adequately inform patients about the possible erosive potential of effervescent tablets, this study was undertaken in order to investigate the erosive potential of effervescent tablets (ET), containing either a combination of vitamins and minerals or vitamins only, commercially available in Switzerland. One hundred and ninety-two bovine enamel samples were prepared and allocated to 16 groups (A–H and 1–8; n = 12/group). Samples were eroded (120 s/erosive cycle) in freshly prepared solutions (200 ml/12 samples) comprised of tap water and a supplement as follows: none (control groups, A and 1); vitamin+mineral ET: Qualite and Prix (B), Optisana (C), Well and Active (D), Actilife All in One (E), Berocca (F), Isostar (G) and Qualite and Prix Mg + Vit C (H); vitamin ET: Actilife-Multivitamin (2), Sunlife Vitamin C (3), Optisana Vitamin C (4), Optisana Multivitamin (5), Well and Active Multivitamin (6), Kneipp Vitamin C+Zink (7) and Sunlife Multivitamin (8). Enamel loss was measured using profilometry after 10 and 20 erosive cycles. For the vitamin+mineral ET, no loss was observed in groups B–E. Significantly highest enamel loss (mean ± SD) after 20 cycles was observed for Isostar (5.26 ± 0.76 µm) and Qualite and Prix Mg + Vit C (5.12 ± 0.67 µm). All vitamine ET showed erosive enamel loss. Significantly highest loss was observed for Sunlife Multivitamin (8.45 ± 1.08 µm), while the lowest loss was observed for Actilife-Multivitamin (5.61 ± 1.08 µm) after 20 cycles. Some of the tested effervescent tablets showed a considerable erosive potential and patients should be informed accordingly.

    Die Bandscheiben sind besonders betroffen von Fehlhaltungen und -stellungen der Wirbelsäule. Sie unterliegen als grösstes zusammenhängendes, nicht vaskularisiertes Gewebe im Menschen, statisch und dynamisch extrem belastet, besonders der Alterung. Um die teilweise sehr starken Schmerzen bei Bandscheibenschädigungen zu lindern, ist eine Operation vielfach die einzige Hilfe. Bei dieser Operation (Nukleotomie) entfernt man das aus der Bandscheibe ausgetretene Gewebe des Gallertkerns (nucleus pulposus), welches durch Druck auf die Nervenstränge im Bereich der Wirbelsäule die Beschwerden (Ischias-Schmerz) verursacht hat. Nach der Entfernung des Gallertkerns werden die auftretenden Kräfte bei veränderter Biomechanik übertragen. Dabei erhalten die Zwischenwirbelgelenke (Facettengelenke) eine erheblich grössere Flächenpressung als dies bei intakter Bandscheibe der Fall war. Die höhere Flächenpressung kommt durch die Verringerung des Abstandes zwischen den oberen und unteren Deckplatten der benachbarten Wirbelkörper zustande, zwischen denen sich der Gallertkern befand. Durch geeignetes Training der Rückenmuskulatur kann eine Stabilisierung des operierten Bandscheibensegmentes erreicht werden, jedoch ist es eine klinische Erfahrung, dass die meisten Patienten, die momentan durch die Operation schmerzfrei geworden sind, keine adäquate zusätzliche sportliche Betätigung auf sich nehmen.

    Vitamin D is a versatile hormone with several functions beyond its well-established role in maintenance of skeletal health and calcium homeostasis. The effects of vitamin D are mediated by the vitamin D receptor, which is expressed together with the vitamin D metabolizing enzymes in the reproductive tissues. The reproductive organs are therefore responsive to and able to metabolize vitamin D locally. The exact role remains to be clarified but several studies have suggested a link between vitamin D and production/release of reproductive hormones into circulation, which will be the main focus of this review. Current evidence is primarily based on small human association studies and rodent models. This highlights the need for randomized clinical trials, but also functional animal and human in vitro studies, and larger, prospective cohort studies are warranted. Given the high number of men and women suffering from reproductive problems and abnormal endocrinology research addressing the role of vitamin D in reproductive endocrinology may be of clinical importance.

  3. Type II dens evaginatus of maxillary central incisor: An alternative approach

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Dens evaginatus is the developmental anomaly of tooth that exhibits protrusion of a tubercle from occlusal surfaces of premolar, and lingual surfaces of maxillary central incisor and lateral incisors. Dens evaginatus is common in Caucasian population. Saudi Arabia is also well evidenced of such cases. These tubercles have an enamel layer covering dentin core containing a thin extension of pulp. These cusp-like protrusions are susceptible to pulp exposure from wear or fracture because of malocclusion. Type II dens evaginatus involves normal pulp with immature root apex. Materials to enhance the pulpal recession or pulpotomy procedures indicated in such cases require long time and efforts to ensure pulpal recession or root maturity, respectively. Also prolonged treatment has risk of fracture of the cusp and reinfection and requires patient commitment for the follow-up procedures. Present case describes the use of mineral trioxide aggregate (MTA in type II dens evaginatus of maxillary central incisor.

    The use of vitamins and minerals to prevent cancer as well as their supportive use in oncological patients is widespread and often occurs without the knowledge of the treating physician. Beyond general recommendations with regard to a balanced and healthy diet, no evidence exists supporting the use of vitamins and minerals in the prevention of cancer. Furthermore, the diet of oncological patients should contain vitamins and minerals of the same quantity as for healthy individuals. In particular, there is currently no rationale for a high-dosage administration of antioxidants. © Georg Thieme Verlag KG Stuttgart · New York.

    1989-01-01

    The results of supplementing crustacean feeds with vitamins are examined specifically from the standpoint of shrimp culture. Micro-nutrients selected for discussion include: water-soluble vitamins of the B-complex, choline and inositol, vitamin C and the fat-soluble group of vitamins: A, D, E and K. Ways in which utilization of vitamins and ultimately dietary demand are altered by physiological state, conditions of culture, as well as factors which impact on feed levels, are explored.

  2. Remote identification of maternal polar bear (Ursus maritimus) denning habitat on the Colville River Delta, Alaska

    Science.gov (United States)

    Blank, Justin J.

    High resolution digital aerial photographs (1 foot pixel size) of the Colville River Delta, Alaska were examined in 3D, with the use of a digital photogrammetric workstation. Topographic features meeting the criteria required for adequate snow accumulation, and subsequent construction of terrestrial polar bear maternal dens, were identified and digitized into an ArcGIS line shapefile. Effectiveness, efficiency, and accuracy were improved when compared to previous polar bear denning habitat efforts which utilized contact photo prints and a pocket stereoscope in other geographic areas of northern Alaska. Accuracy of photograph interpretation was systematically evaluated visually from the air with the use of a helicopter and physically on the ground. Results show that the mapping efforts were successful in identifying den habitat 91.3% of the time. Knowledge denning habitat can improve and inform decision making by managers and regulators when considering travel and development in the study area. An understanding of polar bear denning habitat extent and location will be a crucial tool for planning activities within the study area in a way that minimizes conflicts with maternal dens.

  3. Influence of lifestyle on vitamin bioavailability.

    Science.gov (United States)

    van den Berg, Henk; van der Gaag, Martijn; Hendriks, Henk

    2002-01-01

    In this review the effects of lifestyle factors, especially alcohol consumption, on vitamin bioavailability are summarized and discussed. Alcohol effects are clearly dose-dependent. Excessive chronic alcohol intake is generally associated with vitamin deficiency (especially folate, thiamine, and vitamin B6) due to malnutrition, malabsorption, and ethanol toxicity. Effects of moderate alcohol use are mainly explained by a lower vitamin intake. In the case of vitamin A and beta-carotene, effects on post-absorptive (lipoprotein) metabolism have been demonstrated. In one diet-controlled crossover study, alcohol consumption resulted in an increase in the plasma vitamin B6 (PLP) content, especially after beer consumption (containing vitamin B6), but also after wine and spirit consumption (not containing vitamin B6). Smoking is also associated with a lower dietary vitamin intake. In the case of vitamin C, B12, folate, and beta-carotene, evidence has been presented for effects on postabsorptive metabolism, due to smoke-induced oxidative stress and/or vitamin inactivation. For vitamin E a direct effect of smoking on absorption has been demonstrated. There is no convincing evidence that low-fat diets negatively affect fat-soluble vitamin absorption, but cholesterol-lowering compounds (diets), or unabsorbable fat substitutes, may do so. Vitamin bioavailability may be compromised from certain vegetables (particularly raw), and/or from high-fiber foods, because of limited digestion and inefficient release of vitamins from the food matrix.

    Miscarriage is a common complication of pregnancy that can be caused by a wide range of factors. Poor dietary intake of vitamins has been associated with an increased risk of miscarriage, therefore supplementing women with vitamins either prior to or in early pregnancy may help prevent miscarriage. The objectives of this review were to determine the effectiveness and safety of any vitamin supplementation, on the risk of spontaneous miscarriage. We searched the Cochrane Pregnancy and Childbirth Group Trials Register (6 November 2015) and reference lists of retrieved studies. All randomised and quasi-randomised trials comparing supplementation during pregnancy with one or more vitamins with either placebo, other vitamins, no vitamins or other interventions. We have included supplementation that started prior to conception, periconceptionally or in early pregnancy (less than 20 weeks' gestation). Three review authors independently assessed trials for inclusion, extracted data and assessed trial quality. We assessed the quality of the evidence using the GRADE approach. The quality of evidence is included for numerical results of outcomes included in the 'Summary of findings' tables. We included a total of 40 trials (involving 276,820 women and 278,413 pregnancies) assessing supplementation with any vitamin(s) starting prior to 20 weeks' gestation and reporting at least one primary outcome that was eligible for the review. Eight trials were cluster-randomised and contributed data for 217,726 women and 219,267 pregnancies in total.Approximately half of the included trials were assessed to have a low risk of bias for both random sequence generation and adequate concealment of participants to treatment and control groups. Vitamin C supplementation There was no difference in the risk of total fetal loss (risk ratio (RR) 1.14, 95% confidence interval (CI) 0.92 to 1.40, seven trials, 18,949 women; high-quality evidence); early or late miscarriage (RR 0.90, 95% CI 0.65 to 1

    Takagi, Hisato; Umemoto, Takuya

    2017-02-01

    To summarize the association of vitamins (B6, B12, C, D, and E) and abdominal aortic aneurysm (AAA), we reviewed clinical studies with a comprehensive literature research and meta-analytic estimates. To identify all clinical studies evaluating the association of vitamins B6/B12/C/D/E and AAA, databases including MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials were searched through April 2015, using Web-based search engines (PubMed and OVID). For each case-control study, data regarding vitamin levels in both the AAA and control groups were used to generate standardized mean differences (SMDs) and 95% confidence intervals (CIs). Pooled analyses of the 4 case-control studies demonstrated significantly lower circulating vitamin B6 levels (SMD, -0.33; 95% CI, -0.55 to -0.11; P=0.003) but non-significantly lower vitamin B12 levels (SMD, -0.42; 95% CI, -1.09 to 0.25; P=0.22) in patients with AAA than subjects without AAA. Pooled analyses of the 2 case-control studies demonstrated significantly lower levels of circulating vitamins C (SMD, -0.71; 95% CI, -1.23 to -0.19; P=0.007) and E (SMD, -1.76; 95% CI, -2.93 to 0.60; P=0.003) in patients with AAA than subjects without AAA. Another pooled analysis of the 3 case-control studies demonstrated significantly lower circulating vitamin D (25-hydroxyvitamin D) levels (SMD, -0.25; 95% CI, -0.50 to -0.01; P=0.04) in patients with AAA than subjects without AAA. In a double-blind controlled trial, 4.0-year treatment with a high-dose folic acid and vitamin B6/B12 multivitamin in kidney transplant recipients did not reduce a rate of AAA repair despite significant reduction in homocysteine level. In another randomized, double-blind, placebo-controlled trial, 5.8-year supplementation with α-tocopherol (vitamin E) had no preventive effect on large AAA among male smokers. In clinical setting, although low circulating vitamins B6/C/D/E (not B12) levels are associated with AAA presence, vitamins B6/B12/E

    Full Text Available Faustino R Pérez-López, Gonzalo Pérez-Roncero, María T López-BaenaGrupo de Investigación sobre Salud de la Mujer en Aragón (GRISAMAR, Universidad de Zaragoza, Hospital Clínico Zaragoza, SpainAbstract: Vitamin D is a hormone sequentially produced at different body sites, and which plays a significant role in human health, particularly bone health. However, other roles are emerging. When the serum concentration of vitamin D is very low, the risk of rickets, osteomalacia and osteoporosis is increased. In children and adolescents there is a high prevalence of low vitamin D status, especially in females and during the winter–the prevalence being lower than during the summer. Although there is no unanimous agreement over the minimum values necessary for good health, serum 25-hydroxyvitamin D [25(OHD] levels below 20 ng/mL may be regarded as a vitamin D-deficient condition, and levels between 20–30 ng/mL may be the range of vitamin D insufficiency. Mild low levels have been associated with bone mass accrual alterations in children and adolescents, diminished muscle strength, negative cardiovascular outcomes, insulin resistance and obesity, and neurological disorders. Effective preventive strategies are needed to guarantee adequate vitamin D levels throughout childhood and adolescence, taking into account the geographical setting, season of the year, the level of environmental pollution, skin characteristics, eating habits and body weight, with a view to securing optimum health during these phases, and the prevention of complications in adulthood. There needs to be a renewed appreciation of the beneficial effect of moderate sunlight for providing all humans with the vitamin D needed for ensuring good health. Prolonged sun exposure is not advised, however, due to the risk of skin cancer. In addition, a balanced diet is indicated, since vitamin D-rich foods are better assimilated than supplements. When such conditions cannot be met, then the

    The adverse effects of solar ultraviolet radiation on the skin are well documented, especially in fair-skinned people. These can be ameliorated by photoprotection strategies advocated by many public health bodies and typically include sun avoidance, sunscreen use and clothing. The UVB waveband which is the main cause of all adverse effects investigated in the laboratory to date is also the waveband for vitamin D photosynthesis which is the only established benefit of solar exposure. This is especially important because solar UVB is the main source of vitamin D for most people. There is increasing evidence that vitamin D plays a much greater role in human health than was previously thought. This has given rise to concerns that photoprotection, especially sunscreen use, could adversely affect vitamin D status and human health. Furthermore, it is stated that people with heavily pigmented skins often have poor vitamin D status because of photoprotection by melanin. In this paper we review the effect of photoprotection strategies and pigmentation on vitamin D status. Clothing can clearly be very effective at inhibiting vitamin D synthesis. Sunscreens are effective in theory and some limited human studies support this. However, most studies show little or no effect and the most likely reason for this is that sunscreens have not been applied in the manner that was used to determine their labelled index of protection against sunburn. This could change in the future if public health campaigns and the sunscreen industry are successful in encouraging the public to apply sunscreens more liberally and/or use much higher levels of labelled protection. The role of melanin on vitamin D status is not clear and requires further investigation. Copyright © 2010. Published by Elsevier B.V.

    A radioassay is described for vitamin B12 which involves denaturing serum protein binding proteins with alkali. In the denaturation step a dithiopolyol and cyanide are used and in the intrinsic factor assay step a vitamin B12 analogue such as cobinamide is used to bind with any remaining serum proteins. The invention also includes a kit in which the dithiopolyol is provided in admixture with the alkali. The dithiopolyol may be dithiothreitol or dithioerythritol. (author)

    Given documented social dominance and intraspecific predation in bear populations, the ideal despotic distribution model and sex hypothesis of sexual segregation predict adult female grizzly bears (Ursus arctos) will avoid areas occupied by adult males to reduce risk of infanticide. Under ideal despotic distribution, juveniles should similarly avoid adult males to reduce predation risk. Den-site selection and use is an important component of grizzly bear ecology and may be influenced by multiple factors, including risk from conspecifics. To test the role of predation risk and the sex hypothesis of sexual segregation, we compared adult female (n = 142), adult male (n = 36), and juvenile (n = 35) den locations in Denali National Park and Preserve, Alaska, USA. We measured elevation, aspect, slope, and dominant land cover for each den site, and used maximum entropy modeling to determine which variables best predicted den sites. We identified the global model as the best-fitting model for adult female (area under curve (AUC) = 0.926) and elevation as the best predictive variable for adult male (AUC = 0.880) den sites. The model containing land cover and elevation best-predicted juvenile (AUC = 0.841) den sites. Adult females spatially segregated from adult males, with dens characterized by higher elevations (mean= 1,412 m, SE = 52) and steeper slopes (mean = 21.9°, SE = 1.1) than adult male (elevation: mean = 1,209 m, SE = 76; slope: mean = 15.6°, SE = 1.9) den sites. Juveniles used a broad range of landscape attributes but did not avoid adult male denning areas. Observed spatial segregation by adult females supports the sex hypothesis of sexual segregation and we suggest is a mechanism to reduce risk of infanticide. Den site selection of adult males is likely related to distribution of food resources during spring.

    Compared to their main competitors, African wild dogs (Lycaon pictus) have inferior competitive abilities and interspecific competition is a serious fitness-limiting factor. Lions (Panthera leo) are the dominant large carnivore in African savannah ecosystems and wild dogs avoid them both spatially and temporally. Wild dog young are particularly vulnerable and suffer high rates of mortality from lions. Since lions do not utilize all parts of the landscape with an equal intensity, spatial variation in lion densities can be exploited by wild dogs both during their general ranging behaviour, but more specifically when they are confined to a den with vulnerable young. Since patches of rugged terrain are associated with lower lion densities, we hypothesized that these comparatively safe habitats should be selected by wild dogs for denning. We investigated the relationship between the distribution of 100 wild dog den sites and the occurrence of rugged terrain in four wild dog populations located in Tanzania, Zimbabwe and South Africa. A terrain ruggedness index was derived from a 90 m digital elevation model and used to map terrain ruggedness at each site. We compared characteristics of actual and potential (random) den sites to determine how wild dogs select den sites. The distributions of wild dog dens were strongly associated with rugged terrain and wild dogs actively selected terrain that was more rugged than that available on average. The likelihood of encountering lions is reduced in these habitats, minimizing the risk to both adults and pups. Our findings have important implications for the conservation management of the species, especially when assessing habitat suitability for potential reintroductions. The simple technique used to assess terrain ruggedness may be useful to investigate habitat suitability, and even predict highly suitable denning areas, across large landscapes.

    There are many developmental variations in the permanent dentition. Dens invaginatus can be recognized on many dental X-rays of affected patients, but not every image allows for assessment of the type of malformation. The aim of the present study was to assess the presence of dens invaginatus with radiological features using cone-beam computed tomography (CBCT). CBCT images of 33 patients were evaluated. Age, sex, side, lateralization, occurrence in a particular group of teeth, type of invagination, differentiation, and the consequences of these factors were analyzed. Forty-one teeth with dens invaginatus met the inclusion criteria for this evaluation. Females were affected more frequently than males (57.6 vs. 42.4%, respectively). The patients' age ranged from 7 to 40 years, and the occurrence of dens invaginatus peaked from age 9 to 13 years. In total, 92.7% of affected teeth were present in the maxilla, more often unilaterally (75.8%) than bilaterally (24.2%). The most frequent tooth with dens invaginatus was the maxillary lateral incisor (53.7% of affected teeth). Almost two-thirds (63.4%) of affected teeth were found on the left side and 36.6% were found on the right. The tooth anatomy was distorted within the crown and root. Dens invaginatus sometimes affected other surrounding teeth and reduced their esthetics. The obtained data indicate that CBCT examination is an essential tool in assessing dens invaginatus and can guide dental practitioners in treating patients who exhibit characteristic features of this disorder. CBCT allows the clinician to distinguish the type of anomaly.

We define the term ‘naturalism’ and explain, in which way naturalistic attitudes may occur and which questions they are related to. Based on a theological and philosophical criticism of naturalism we want to encourage teachers of religion to openly question such worldviews. To do so, we refer to the concept of ‘philosophy/theology for children/adolescents’. We argue to use the so-called ‘Socratic Method’ in its original sense, namely the challenging of alleged certainties (elenchus. The Socratic Method can and should be used not only to philosophize freely, but also to question pupils’ (naturalistic worldviews and attitudes, not with the purpose to then impose a ‘correct’ worldview onto them, but to help deconstructing alleged certainties and opening new horizons of thought.

    American adults take many types of vitamin supplements, despite limited evidence of their efficacy, especially in preventing chronic diseases such as cardiovascular disease and cancer. Supplements contain significant amounts of vitamins when consumed from multiple sources. Excess consumption of some vitamins may have detrimental health effects. Use of MMVM products appears to be safe; however, clinical outcomes have not been established. Although vitamin D and preconception folic acid may be appropriate for self care, a health care provider should monitor other vitamin supplements for disease prevention, such as niacin. Beyond supplementation as treatment for vitamin deficiencies, evidence is lacking.

    This article reviews the current literature addressing the treatment of schizophrenia with vitamin supplementation. It describes the important roles that vitamins play in normal metabolism, and reviews the evidence pertaining to vitamin deficiency and supplementation in patients with schizophrenia. There is mounting evidence suggesting that vitamin supplementation, in particular with folic acid, vitamin B12 and vitamin D, may be important in treatment within certain subgroups of patients. There is a need for larger randomized controlled trials, and further studies examining the incidence of schizophrenia in countries with poor prenatal care and malnutrition, as well as in countries that have adopted mandatory folic acid fortification of grain products, are recommended.

    Vitamins are essential organisms which promote various metabolisms and physiological systems. Several vitamins play important roles in hematopoietic system. Vitamin B12, C and folic acid are associated with DNA synthesis of erythroid nucleus, the deficiency of which causes the megaloblastic anemia. Some megaloblatic anemia and sideroblastic anemia might response to vitamin B1 and B6, respectively. Vitamin K participates in some coagulation factors in coagulation-fibrinogenolysis system. It has been reported that vitamins A, D and K potentially differentiate leukemic cells and then induce the apoptosis, suggesting that they would be new therapeutic agents in acute leukemia.

    Vitamin D Deficiency (VDD) is responsible for a wide spectrum of clinical diseases and vitamin D deficiency prevalence is frightening in most parts of the world including Pakistan. Therefore, supplementations of vitamin D are used in the population at high risk for the prevention and the treatment of vitamin D deficiency. Vitamin D supplementation comes in various formulations both oral and intramuscular. Cholecalciferol is the most commonly used preparation which is given through these routes of administration. There is need to study the fact that how much vitamin D levels are raised after administration of these different formulations as this can be a pivotal factor in determining dosage and route of vitamin D3. Methods: This cross-sectional study conducted on 320 cases and compared the efficacy of various Vitamin D3 preparations in raising Vitamin D levels conducted in Department of Endocrinology and Metabolism, Services Hospital, Lahore from February to July, 2016. Blood serum was drawn for vitamin D level in the cases at the time of presentation and after treatment. Results: Three hundred and twenty patients were enrolled in study and divided into four groups (A, B, C, D). There was no significant difference between groups (A, B, C, D) in change in vitamin d levels after 3 months of treatment (p-Value 0.446). Conclusion: Different preparations of vitamin D are equally effective in raising vitamin D levels at 12 weeks. However, there is a need to conduct large scale studies to further validate these results. (author)

    Vitamin D is one of the oldest hormones that have been made in the earliest life forms for over 750 million years. Phytoplankton, zooplankton, and most plants and animals that are exposed to sunlight have the capacity to make vitamin D. Vitamin D is critically important for the development, growth, and maintenance of a healthy skeleton from birth until death. The major function of vitamin D is to maintain calcium homeostasis. It accomplishes this by increasing the efficiency of the intestine to absorb dietary calcium. When there is inadequate calcium in the diet to satisfy the body's calcium requirement, vitamin D communicates to the osteoblasts that signal osteoclast precursors to mature and dissolve the calcium stored in the bone. Vitamin D is metabolized in the liver and then in the kidney to 1,25-dihydroxyvitamin D [1,25(OH)(2)D]. 1,25(OH)(2)D receptors (VDR) are present not only in the intestine and bone, but in a wide variety of other tissues, including the brain, heart, stomach, pancreas, activated T and B lymphocytes, skin, gonads, etc. 1,25(OH)(2)D is one of the most potent substances to inhibit proliferation of both normal and hyperproliferative cells and induce them to mature. It is also recognized that a wide variety of tissues, including colon, prostate, breast, and skin have the enzymatic machinery to produce 1,25(OH)(2)D. 1,25(OH)(2)D and its analogs have been developed for treating the hyperproliferative disease psoriasis. Vitamin D deficiency is a major unrecognized health problem. Not only does it cause rickets in children, osteomalacia and osteoporosis in adults, but may have long lasting effects. Chronic vitamin D deficiency may have serious adverse consequences, including increased risk of hypertension, multiple sclerosis, cancers of the colon, prostate, breast, and ovary, and type 1 diabetes. There needs to be a better appreciation of the importance of vitamin D for overall health and well being. Copyright 2002 Wiley-Liss, Inc.

    Vitamin D has an important role in pregnancy in promoting fetal skeletal health. Maternal dietary intake is a key factor influencing both maternal and fetal status. There are limited data available on food groups contributing to vitamin D intake in pregnancy. The aim of this study was to determine dietary intakes of vitamin D throughout pregnancy in 64 women and to determine the main food groups contributing to vitamin D intake. Results showed that median dietary intakes of vitamin D ranged from 1.9-2.1 μg\\/d during pregnancy, and were 80% below the current recommendation. The principal food groups contributing to vitamin D intake were meat, egg and breakfast cereal groups. Oily fish, the best dietary source of vitamin D, was consumed by <25% of women. These data call for more education; they question the role of vitamin D supplementation and highlight the contribution of other food groups more frequently consumed, namely, breakfast cereals, meat and eggs.

    Full Text Available Prostate cancer is the second common cancer in men worldwide. The prevention of prostate cancer remains a challenge to researchers and clinicians. Here, we review the relationship of vitamin D and sunlight to prostate cancer risk. Ultraviolet radiation of the sunlight is the main stimulator for vitamin D production in humans. Vitamin D's antiprostate cancer activities may be involved in the actions through the pathways mediated by vitamin D metabolites, vitamin D metabolizing enzymes, vitamin D receptor (VDR, and VDR-regulated genes. Although laboratory studies including the use of animal models have shown that vitamin D has antiprostate cancer properties, whether it can effectively prevent the development and/or progression of prostate cancer in humans remains to be inconclusive and an intensively studied subject. This review will provide up-to-date information regarding the recent outcomes of laboratory and epidemiology studies on the effects of vitamin D on prostate cancer prevention.

    Vitamin D receptors and vitamin D metabolizing enzymes are present in the central nervous system. Calcitriol (the active vitamin D hormone) affects numerous neurotransmitters and neurotrophic factors, relevant for mental disorders. In the case of depressive disorders, considerable evidence supports a role of suboptimal vitamin D levels. However, the data are not conclusive and further studies are necessary. Especially, the relative importance of the pineal-melatonin system versus the vitamin D-endocrine system for the pathogenesis of seasonal affective disorders is presently unresolved. Two diagnoses, schizophrenia and autism, have been hypothetically linked to developmental (prenatal) vitamin D deficiency, however, also in adult patients, low levels have been reported, supporting the notion that vitamin D deficiency may not only be a predisposing developmental factor but also relate to the adult patients' psychiatric state. Two cases are described, whose psychiatric improvement coincided with effective treatment of vitamin D deficiency. Copyright © 2010 Elsevier B.V. All rights reserved.

    The vitamin D status depends on the production of vitamin D3 in the skin under the influence of ultraviolet radiation and vitamin D intake through the diet or vitamin D supplements. The serum 25-hydroxyvitamin D (25(OH)D) concentration is the parameter of choice for the assessment of vitamin D status. Low serum levels of calcium and phosphate and an elevated level of alkaline phosphatase can also point to vitamin D deficiency. Usually, between 50% and 90% of vitamin D in the body is coming from the production in the skin and the remainder is from the diet. The production of vitamin D3 in the skin depends on sunshine exposure, latitude, skin-covering clothes, the use of sun block and skin pigmentation. In general, serum 25(OH)D is lower with higher latitudes and with darker skin types, but there are exceptions. Vitamin D deficiency (serum 25(OH)DAmerica where vitamin D deficiency is uncommon but vitamin D insufficiency (serum 25(OH)D between 25 and 50 nmol/l) is still common. In the United States and Canada milk is usually supplemented with vitamin D and the use of vitamin supplements is relatively common. Vitamin D status in Latin America usually is reasonable but there are exceptions and vitamin D insufficiency still occurs quite often. In Australia and New Zealand a poor vitamin D status was seen in the elderly who were often vitamin D deficient and also in immigrants from Asia. Vitamin D deficiency also occurred in children when the mother was vitamin D deficient. Within Europe, vitamin D status usually is better in the Nordic countries than around the Mediterranean. This may be due to a lighter skin and sun seeking behaviour and a high consumption of cod liver oil in the Northern countries while in Southern Europe people stay out of the sunshine and have a somewhat darker skin. A very poor vitamin D status was observed in non-western immigrants, especially in pregnant women. In conclusion, vitamin D deficiency and insufficiency are globally still very common

  16. Vitamin A and Vision.

    Visual systems detect light by monitoring the effect of photoisomerization of a chromophore on the release of a neurotransmitter from sensory neurons, known as rod and cone photoreceptor cells in vertebrate retina. In all known visual systems, the chromophore is 11-cis-retinal complexed with a protein, called opsin, and photoisomerization produces all-trans-retinal. In mammals, regeneration of 11-cis-retinal following photoisomerization occurs by a thermally driven isomerization reaction. Additional reactions are required during regeneration to protect cells from the toxicity of aldehyde forms of vitamin A that are essential to the visual process. Photochemical and phototransduction reactions in rods and cones are identical; however, reactions of the rod and cone visual pigment regeneration cycles differ, and perplexingly, rod and cone regeneration cycles appear to use different mechanisms to overcome the energy barrier involved in converting all-trans- to 11-cis-retinoid. Abnormal processing of all-trans-retinal in the rod regeneration cycle leads to retinal degeneration, suggesting that excessive amounts of the retinoid itself or its derivatives are toxic. This line of reasoning led to the development of various approaches to modifying the activity of the rod visual cycle as a possible therapeutic approach to delay or prevent retinal degeneration in inherited retinal diseases and perhaps in the dry form of macular degeneration (geographic atrophy). In spite of great progress in understanding the functioning of rod and cone regeneration cycles at a molecular level, resolution of a number of remaining puzzling issues will offer insight into the amelioration of several blinding retinal diseases.

    New strategies are presented for matching heat supply and demand on the basis of a bus technology. Investment costs are at a minimum as the automation stations are activated by introducing new programs. (orig.) [German] Seit einiger Zeit wird ueber verschiedene Regelungsstrategien versucht, die Energiebereitstellung so an den Bedarf (Verbraucher) anzupassen, dass die Waermeverluste beim Transport auf den Zuleitungen sowie in der Energiezentrale minimiert werden. Fuer mehrere Anwendungen aus dem Bereich der Heizungs-, Lueftungs- und Klimatechnik sollen hier neue Strategien vorgestellt werden, die erst mit dem Einsatz der Bus-Technologien in der Gebaeudeautomation moeglich sind. Fuer die Betrachtungen ist es auch von Wichtigkeit, dass zu deren Umsetzung moeglichst keine zusaetzlichen Investitionskosten erforderlich sind, sondern dass die in den Automationsstationen durch Einfuegen neuer Programme zu aktivieren sind.

    Vitamins are known to be sensitive to the effects of ionizing radiation. Since most foods contain a large proportion of water, the most probable reaction of the ionizing radiation would be with water; and as vitamins are present in very small amounts compared with other substances in the food they will be affected indirectly by the radiation. This chapter discusses the effect of ionizing radiation on water soluble vitamins and fat soluble vitamins. (author)
