Abstract The aim of the present study was to examine associations between serum 25-hydroxyvitamin D [25(OH)D] and 1,25-dihydroxyvitamin D[(1,25(OH)2D]—the circulating and active forms of vitamin D—and periodontal infection. The data were gathered from a case-control study (63 periodontitis patients and 30 periodontally healthy controls) and an intervention study among individuals with type 1 diabetes mellitus (T1DM, 80 patients at the baseline and 65 after periodontal treatment). The periodontal data and the levels of serum 25(OH)D, 1,25(OH)2D and parathyroid hormone (PTH) were available. A th

Abstract:

Background: The interest of vitamin D has increased in the last years. That is because there is so many possible positive effects of vitamin D and also because many individuals has vitamin D deficiency. Modern man spends much time indoors which leads to lower levels of vitamin D. People who have emigrated from a sunny climate to a Nordic climate often gets a deficiency due to a more pigmented skin which requires a larger amount of UVB to get an adequate synthesis of vitamin D.

Abstract:

During the industrialization of the 19th century the negative health effects of vitamin D was discovered as children in the cities developed osteomalacia or more commonly known as rickets caused by vitamin D deficiency. Vitamin D is produced in the skin from 7-dehydrocholesterol during sun-exposure and enhances intestinal phosphor and calcium absorption thus enhancing the bone remodeling process. Now, in the 21st century, Vitamin D is still relevant as positive health effects have been recognized and with it an increased number of samples and a demand for accurate analyzing.

Bakgrund: Vitamin D finns i två olika former, det animaliska D3 (kolekalciferol) och det vegetabiliska D2 (ergokalciferol). Det har rått olika åsikter bland läkarkåren och allmänheten om vilken av de två formerna som är mest potent för att höja 25(OH)D-statusen i blodet, det värde som mäts för att avgöra vitamin D-halten i kroppen. Då vitamin D-brist är vanligt förekommande bland befolkningen i Norden är det viktigt att veta vilken form som har bäst effekt och som därför bör användas för att behandla och förebygga vitamin D-brist.

Abstract:

In systemic lupus erythematous (SLE), mesenchymal stromal cells (MSCs) are defective and may present early signs of senescence. In a previous study we demonstrated as the treatment with hydroxychloroquine may influence the clonogenic potential of MSCs in a SLE animal model. Vitamin D may influence several aspects of the innate and adaptative immune response and low serum levels of vitamin D are common in SLE patients and were correlated to higher disease activity and severity.

Prostate cancer is the leading male cancer form i Sweden and maybe worldwide as well. Vitamin D is synthesized in the skin following the exposure to sunlight. Researcers have long been aware of the positive effect that vitamin D3 has on prostate tumour growth. 1,25(OH)2D3 have for a long time been the target of these studies and have shown good results. The steroid hormone induces cAMP accumulation and activiates the cAMP dependent protein kinaseA (PKA). PKA is then able to activate a transcription regulating protein. 1,25(OH)2D3 is known to cause LNCaP cells to accumulate in the G1 phase ofth

Abstract:

In humans, the epidermis is the main site for the synthesis of Vitamin D3 (cholecalciferol) from 7-dehydrocholesterol. Cholecalciferol undergoes further hydroxylation in the liver and kidney to produce the active form of the circulating hormone 1α,25-dihydroxyvitamin D3 (1,25(OH)2D3). In target cells, 1,25(OH)2D3 interacts with the specific intracellular vitamin D receptor (VDR), a member of the nuclear receptor superfamily. However, epidermal keratinocytes, in addition to being target cells, have enzymes required for autocrine production of 1,25(OH)2D3. They can convert cholecalciferol to 1,2

However, double-blind clinical trials on the efficacy of vitamin D3 supplementation in breast cancer have been inconclusive.

Abstract:

Although maternal vitamin D status has been linked to asthma in offspring, the relationship between vitamin D status and asthma in adults still remains unclear. The current study assessed the relationship between measures of vitamin D status and self-reported asthma/wheeze in 186 healthy women aged 18-30 years. Although the risk of asthma/wheeze symptoms was three-times higher among women with low dietary vitamin D intake (<200 IU>/day) than in those with higher vitamin D intake, suboptimal serum levels of 25(OH)D ( <70 nmol>/L) were associated with a 48% lower risk of asthma/wheeze than “opti

Abstract:

Vitamin D deficiency has been linked with many health problems. Early research demonstrated the importance of vitamin D for bone health, but it may also play a larger role than first reported in muscle health and function. Specifically, low vitamin D may hinder athletic performance, as such evaluation of serum vitamin D levels in high volume training athletes has merit. The purpose of this study was to evaluate serum levels of 25(OH)D in college athletes to determine how many had levels below the recommended values. Data from student-athletes who were attending a large university in the south

Abstract:

Vitamin D deficiency and/or reduced function, as per certain polymorphisms of the vitamin D receptor (VDR) gene, have been related to several autoimmune disorders. The present study was aimed to investigate the association of Hashimoto's thyroiditis with vitamin D status and functional polymorphisms (SNPs) of the VDR gene. In this case-control study, 200 euthyroid subjects were enrolled: 100 newly diagnosed HT patients (87 F, 13 M; mean age ± SD 42 ± 15 year) and 100 healthy individuals, matched for age, sex, BMI, and month of blood sampling. Serum 25(OH)D3 was measured by HPLC. The VDR SNPs B

Abstract:

Objectives: To assess the association between serum 25(OH)D and body mass index (BMI) in pre- and early-adolescents and to determine whether this association varies by demographic/clinical characteristics. Methods: Vitamin D status was determined using serum 25(OH)D in healthy pre- and early adolescents in Pittsburgh, PA (deficiency=/mL, insufficiency=12-/mL, sufficiency=≥20 ng/mL). Adiposity was quantified using BMI percentile (normal=<85th, overweight=>85th-95th, obese=>95th). The relationship between serum 25(OH)D and adiposity was assessed in the total population and after stratification b

Abstract:

Vitamin D status is assessed with circulating 25-hydroxyvitamin D [25(OH)D]. As some evidence suggests that low vitamin D status adversely affects neonatal health, this project aimed to determine the association between cord blood 25(OH)D levels and preterm birth (PTB; <37 weeks gestation), low birthweight (LBW; <2500 grams) and small for gestational age (SGA; <10th percentile) and to examine the relationship between maternal 25(OH)D levels during the first trimester of pregnancy and fetal 25(OH)D levels at birth in a Canadian population.

Abstract:

Master of Science<br>Department of Animal Sciences and Industry<br>Jim Nelssen<br>A thorough literature review on feeding vitamin D₃ and 25(OH)D₃ revealed a large amount of research conducted in swine and poultry. In general, increasing vitamin D₃ concentrations or adding 25(OH)D₃ to the maternal diet increases the vitamin D₃ status of the dam and often the progeny as well. Varying results have been reported on the practical and valuable impacts of this elevated status with some topics including improved sow performance, changes in muscle fiber morphometrics, and growth performance to market.
