Sci Rep 2022; 12:4022. [PMID: 35256737 PMCID: PMC8901712 DOI: 10.1038/s41598-022-07989-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2021] [Accepted: 02/28/2022] [Indexed: 12/15/2022] Open
Abstract
A previous randomised controlled trial showed that an anti-inflammatory diet (AID) significantly reduced gingival inflammation despite constant plaque values. This exploratory study investigated the role of serum fatty acids in relation to the observed clinical effects. Therefore, data of thirty participants with gingivitis, following either a pro-inflammatory dietary pattern (PID) rich in saturated fat, omega 6 fatty acids, and refined carbohydrates or an AID for 4 weeks, were correlated with corresponding serum samples for a variety of fatty acids. Changes in the fatty acid profile and effects on clinical periodontal parameters were analysed. Results showed that the polyunsatured:saturated fatty acids ratio (PUFA:SFA ratio) and nervonic acid level were significantly higher in the AID group than in the PID group at the end of the study. Significant intragroup differences were seen only in the AID group. Diverse fatty acids showed heterogeneous relations to clinical parameters. This study demonstrated that the serum fatty acid profile was not fundamentally associated with the clinical gingivitis-lowering effects of an AID in short-term, although some fatty acids showed individual relations to clinical parameters with respect to inflammation. Hence, short-term effects of dietary therapy on gingivitis may be rather based on carbohydrate-related effects and/or micronutrients.

Abstract
The aim of this study was to determine the effects of n-3 ingestion on periodontal disease. Besides, we also investigated the relationship between plasma concentrations of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and/or aracdonic acid (AA), and periodontal disease. An electronic search was performed in several databases with the following keywords: "n-3," DHA, EPA and polynsaturated fatty acids (PUFA) in combination with the term "periodontal disease" (PD). Only studies conducted with humans, involving clinical parameters of PD assessment and use of n-3 were selected, without restriction to the date of publication. The search has returned 1368 articles, 11 of which were selected. The results were separated according to the type of n-3 ingestion: supplementation or n-3 content in normal diet. In the studies where n-3 has been supplemented, there was no significant difference in the clinical severity of PD compared to the control subjects. However, in patients where levels of n-3 were evaluated in a usual diet, a lower disease severity was reported. We have detected a preventive effect related to plasma levels of EPA and DHA against PD progression. Thus, n-3 ingestion may beneficially interfere in PD progression, depending on the duration and dosage of consumption.

Role of Lipids in the Onset, Progression and Treatment of Periodontal Disease. A Systematic Review of Studies in Humans. Int J Mol Sci 2016; 17:ijms17081202.

Abstract
The risk of different oral problems (root caries, tooth mobility, and tooth loss) can be increased by the presence of periodontal disease, which has also been associated with a growing list of systemic diseases. The presence of some bacteria is the primary etiology of this disease; a susceptible host is also necessary for disease initiation. In this respect, the progression of periodontal disease and healing of the periodontal tissues can be modulated by nutritional status. To clarify the role of lipids in the establishment, progression, and/or treatment of this pathology, a systematic review was conducted of English-written literature in PubMed until May 2016, which included research on the relationship of these dietary components with the onset and progression of periodontal disease. According to publication type, randomized-controlled trials, cohort, case-control and cross-sectional studies were included. Among all the analyzed components, those that have any effect on oxidative stress and/or inflammation seem to be the most interesting according to current evidence. On one hand, there is quite a lot of information in favor of a positive role of n-3 fatty acids, due to their antioxidant and immunomodulatory effects. On the other hand, saturated fat-rich diets increase oxidative stress as well the as intensity and duration of inflammatory processes, so they must be avoided.

Abstract
OBJECTIVES The aim of this article is to present an overview of omega-3 fatty acids, their anti-inflammatory properties and potential use as an adjunct for periodontal therapy. MATERIALS AND METHODS A general literature search was conducted to provide an overview of omega-3 fatty acids, their metabolism and anti-inflammatory properties. A more specific literature search of PubMed and EMBASE was conducted to identify articles dealing studies investigating the effects of omega-3 fatty acids in the treatment of periodontitis in animals and humans and included cross-sectional, longitudinal and intervention designs. RESULTS To date, there is good emerging evidence that dietary supplementation with fish oil may be of some benefit and this is enhanced if combined with aspirin. All clinical intervention studies to date have been on small sample sizes, and this indicates there is need for larger and more robust clinical trials to verify these initial findings. CONCLUSIONS Dietary supplementation with fish oil could be a cost-effective adjunctive therapy to the management of periodontal disease. CLINICAL RELEVANCE The host modulatory properties of omega-3 fatty acids warrant further assessment of their use as an adjunct in the management of periodontitis.

Abstract
Adipokines are present in inflammatory processes and may be directly related to periodontal disease. Moreover, their activities may be regulated by fatty acids. The goal of this study was to quantify the concentrations of the main adipokines, leptin, adiponectin and resistin, and the docosahexaenoic (DHA), docosapentaenoic (DPA), eicosapentaenoic (EPA) and arachidonic (AA) fatty acids, in patients with generalized chronic periodontitis. As a secondary objective, the ratios of these substances in the blood of these patients were evaluated. The study included 15 systemically healthy patients with generalized chronic periodontitis (test group) and 15 patients with gingivitis (control group). Medical and periodontal parameters and blood samples were collected. Serum concentrations of fatty acids were analyzed by gas chromatography and adipokines by multiplex bead immunoassay. There was no significant difference in adipokines between groups. However, there was a tendency for lower values of adiponectin in periodontitis patients. Regarding the fatty acids, they were significantly higher in the test group compared with controls. The res/DHA, res/AA, adipon/DHA, adipon/AA and adipon/DPA ratios were significantly lower in the test group. There was no significant correlation between adipokines and clinical parameters and between adipokines and fatty acids levels. It was concluded that generalized chronic periodontitis patients showed significantly higher levels of fatty acids in comparison to gingivitis; adiponectin revealed a trend to lower values in the periodontitis group, even after Ancova correction. The ratios suggest a minor proportion of adiponectin and resistin in relation to the fatty acids in patients with generalized chronic periodontitis.

Abstract
BACKGROUND Plasma levels of polyunsaturated fatty acids (PUFAs) are different before and after periodontal treatment. Asians and Westerners have significantly different baseline levels of plasma PUFAs. However, no Asian study has reported the effects of nonsurgical treatment on the correlation between periodontal condition and plasma levels of PUFAs. We analyzed whether recovery from periodontitis was correlated with the elevation of plasma fatty acids 3 months after the nonsurgical intervention and with no recommended supplements. DESIGN Thirty-five Taiwanese patients with periodontitis were recruited. Probing pocket depths (PPDs) and clinical attachment levels (CALs) were measured at baseline and 3 months after the nonsurgical treatment. Plasma levels of fatty acids were determined using gas chromatography. Differences and correlations between plasma fatty acid composition and periodontitis severity at baseline and 3 months after treatment were determined. RESULTS Twenty-six patients completed the study. At the baseline, PPDs were negatively correlated with plasma n-3 PUFAs (r=-0.52, p<0.01), but at 3 months post intervention, periodontitis severity had declined and the weight percentages of n-3 PUFAs, DPA, and DHA were significantly (p=0.019, 0.005, and 0.037, respectively) higher. The recovery percentages of CALs were positively and significantly correlated with plasma ΔPUFAs and the percentage of Δn-3 PUFAs in ΔPUFAs (r=0.42 and 0.45, respectively; p<0.05 for both). CONCLUSIONS We conclude that a higher weight percentage of n-3 PUFAs in total PUFAs was related to the recovery of CALs 3 months after the nonsurgical periodontal treatment. However, no such relationship was found for PPDs.

Abstract
Several reports have indicated that dietary intake of DHA is associated with lower prevalence of periodontitis. In the present study, we investigated the effect of DHA on the production of proinflammatory mediators in murine macrophage-like RAW264.7 cells stimulated with lipopolysaccharide (LPS) isolated from Prevotella intermedia, a pathogen implicated in inflammatory periodontal disease, and its mechanisms of action. LPS was isolated from lyophilised P. intermedia ATCC 25,611 cells using the standard hot-phenol-water protocol. Culture supernatants were collected and assayed for NO, IL-1β and IL-6. Real-time PCR analysis was carried out to detect the expression of inducible NO synthase (iNOS), IL-1β, IL-6 and haeme oxygenase-1 (HO-1) mRNA. Immunoblot analysis was carried out to quantify the expression of iNOS and HO-1 protein and concentrations of signalling proteins. DNA-binding activities of NF-κB subunits were determined using an ELISA-based assay kit. DHA significantly attenuated the production of NO, IL-1β and IL-6 at both gene transcription and translation levels in P. intermedia LPS-activated RAW264.7 cells. DHA induced the expression of HO-1 in cells treated with P. intermedia LPS. Selective inhibition of HO-1 activity by tin protoporphyrin IX significantly mitigated the inhibitory effects of DHA on LPS-induced NO production. DHA significantly attenuated the phosphorylation of c-Jun N-terminal kinase induced by LPS. In addition, DHA suppressed the transcriptional activity of NF-κB by regulating the nuclear translocation and DNA-binding activity of NF-κB p50 subunit and inhibited the phosphorylation of signal transducer and activator of transcription 1. Further in vivo studies are needed to better evaluate the potential of DHA in humans as a therapeutic agent to treat periodontal disease.

Abstract
Aggressive periodontitis (AgP) is a rapidly progressing type of periodontal disease in otherwise healthy individuals which causes destruction of the supporting tissues of the teeth. The disease is initiated by pathogenic bacteria in the dental biofilm, and the severity of inflammation and attachment loss varies with the host response. Recently, there has been an increased interest in determining the role of lipid mediators in inflammatory events and the concept of pro-inflammatory and pro-resolution lipid mediators has been brought into focus also in periodontal disease. The present study aimed to determine the profile of omega-3 or n3- as well as omega-6 or n6- polyunsaturated fatty acids (PUFAs) and PUFA-metabolites of linoleic acid, arachidonic acid (AA), eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in gingival crevicular fluid (GCF), saliva and serum in AgP patients and healthy controls. In total, 60 selected n3- and n6-PUFAs and various PUFA metabolites were measured using high performance liquid chromatography-tandem electrospray ionisation mass spectrometry (HPLC-ESI-MS-MS). Of these, 51 could be quantified in this study. The concentrations of the majority were low in saliva samples compared with serum and GCF, but were mainly higher in AgP patients compared with healthy controls in all three kinds of sample. Ratios of n3- to n6-PUFAs (DHA + EPA)/AA were significantly lower in the GCF of AgP patients than in the healthy controls. Furthermore, various ratios of the direct precursors of the pro-resolution lipid mediators (precursors of resolvins and protectins) were calculated against the precursors of mainly pro-inflammatory lipid mediators. These ratios were mainly lower in GCF and saliva of AgP patients, compared with healthy controls, but only reached significance in GCF (P<0.05). To conclude, the ratios of precursors of pro-resolution/pro-inflammatory lipid mediators seem to be more relevant for describing the disease status of AgP than the concentration of specific lipid mediators.

Abstract
Both diabetes and periodontitis are chronic diseases. Diabetes has many adverse effects on the periodontium, and conversely periodontitis may have deleterious effects further aggravating the condition in diabetics. The potential common pathophysiologic pathways include those associated with inflammation, altered host responses, altered tissue homeostasis, and insulin resistance. This review examines the relationship that exists between periodontal diseases and diabetes mellitus with a focus on potential common pathophysiologic mechanisms.

We report here differences in the fatty acid profile of cancellous bone matrix, including n-3, n-6, mono- and poly-unsaturated, as well as saturated fats, between femoral heads from female OA (n=8, aged 68-88years), fractured neck of femur (#NOF) (n=19, 67-88years) and autopsy controls (CTRL) (n=4, 85-97years). Femoral heads were collected from individuals undergoing orthopaedic surgery for OA or #NOF; the fatty acid profile of sub-samples from the superior principal compressive and superior principal tensile regions were determined by gas chromatography. A total of 42 individual fatty acids were detected at varying concentrations with significant differences between subchondral bone from OA subjects, subchondral bone from #NOF subjects and subchondral bone from CTRL subjects, as well as between the superior principal compressive and superior principal tensile regions (for saturated fats only). Subchondral bone from OA subjects had higher total n-6 (OA=10.89±3.17, #NOF=11.11±1.83, CTRL=8.32±2.05, p=0.008) and total n-3 (OA=1.34±0.38, #NOF=1.19±0.18, CTRL=1.15±0.48, p=0.011) percentages than subchondral bone from #NOF subjects and subchondral bone from CTRL subjects, and there was no difference in the n-6:n-3 ratio, nor within the percentage of n-9 fatty acids. Arachidonic acid (OA=0.42±0.16, #NOF=0.26±0.06, CTRL=0.28±0.06, p=0.01), and γ-linolenic acid (OA=0.11±0.03, #NOF=0.05±0.02, CTRL=0.04±0.02, p<0.001) were higher in subchondral bone from OA subjects than subchondral bone from #NOF subjects and subchondral bone from CTRL subjects. In conclusion, there is a wide diversity of fatty acids in cancellous bone matrix from the femoral heads of OA and #NOF, suggesting they may have regulatory effects on inflammatory processes, and their metabolites. This article is part of a Special Issue entitled "Osteoarthritis".

Abstract
BACKGROUND Long-chain polyunsaturated fatty acids omega-3 and omega-6 (LC-PUFA n-3 and n-6) can function as important inflammatory modulators and also have a strong effect in the proresolving inflammatory processes. The aim of the authors is to analyze the serum levels of docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA), and arachidonic acid (AA) in patients with generalized chronic periodontitis (GCP) and compare these results with serum levels of patients with gingivitis only. METHODS Twenty-one patients with untreated GCP (mean age: 46.0 ± 8.8 years) and 16 patients with gingivitis only (mean age: 31.5 ± 7.5 years) were investigated. The clinical examination included probing depth (PD), clinical attachment level, bleeding on probing, and plaque index. Blood samples were analyzed for the presence of DHA, EPA, DPA, and AA using gas chromatography. RESULTS Significantly higher levels of DHA, DPA, EPA, and AA were observed in patients with GCP when compared with patients with gingivitis (P = 0.007, P = 0.004, P = 0.033, and P = 0.001, respectively). The differences were still significant even after the adjustments for age and sex. The PD showed a significant positive correlation with DHA (r = 0.5; P = 0.003), DPA (r = 0.6; P <0.001), and AA (r = 0.6; P <0.001). CONCLUSION The present findings suggest that serum levels of LC-PUFA n-3 and n-6 may be affected by the severity of periodontal disease.

Abstract
Resolution of inflammation is an active temporally orchestrated process demonstrated by the biosynthesis of novel proresolving mediators. Dysregulation of resolution pathways may underlie prevalent human inflammatory diseases such as cardiovascular diseases and periodontitis. Localized Aggressive Periodontitis (LAP) is an early onset, rapidly progressing form of inflammatory periodontal disease. Here, we report increased surface P-selectin on circulating LAP platelets, and elevated integrin (CD18) surface expression on neutrophils and monocytes compared to healthy, asymptomatic controls. Significantly more platelet-neutrophil and platelet-monocyte aggregates were identified in circulating whole blood of LAP patients compared with asymptomatic controls. LAP whole blood generates increased pro-inflammatory LTB4 with addition of divalent cation ionophore A23187 (5 µM) and significantly less, 15-HETE, 12-HETE, 14-HDHA, and lipoxin A(4). Macrophages from LAP subjects exhibit reduced phagocytosis. The pro-resolving lipid mediator, Resolvin E1 (0.1-100 nM), rescues the impaired phagocytic activity in LAP macrophages. These abnormalities suggest compromised resolution pathways, which may contribute to persistent inflammation resulting in establishment of a chronic inflammatory lesion and periodontal disease progression.

Abstract
The longitudinal relationship between dietary n-6 to n-3 PUFAs ratio and periodontal disease in 235 Japanese subjects for whom data were available for the years 2003-2006 was investigated. PUFAs intake was assessed at baseline with a brief-type self-administered diet history questionnaire. Full-mouth periodontal status, measured as the clinical attachment level (CAL), was recorded at baseline and once a year for 3 years. The number of teeth with a change in the loss of CAL ≥3 mm at any site over a year was calculated as 'periodontal disease events'. Poisson regression analysis was conducted, with dietary n-6 to n-3 PUFAs ratio as the main predictor, to estimate its influence on periodontal disease events. A high dietary n-6 to n-3 PUFAs ratio was significantly associated with greater number of periodontal disease events. The findings suggest the dietary n-6 to n-3 PUFAs ratio is associated with periodontal disease among older Japanese.

Abstract
BACKGROUND AND AIMS In periodontitis it has been found that some perturbation exists in lipid biomarkers, such as increased serum total cholesterol and low-density lipoprotein cholesterol. Nevertheless, the relationship between fatty acids and periodontitis has been demonstrated only in a few studies and remains controversial. The aim of this investigation was to explore the effects of periodontitis on a cluster of traditional and novel cardiovascular risk factors such as plasma-lipids profile, types of plasma fatty acids, adhesion molecules and systemic inflammatory markers. METHODS AND RESULTS At a university dental school, 56 patients all over 35 years old were enrolled and invited to participate in the study. Total plasma fatty acids, saturated, n-6 polyunsaturated and monounsaturated fatty acids, peroxidability index, soluble VCAM, TNF-alpha, cholesterol, triacylglycerols, and VLDL-c were significantly higher in the periodontitis group compared to the non-periodontitis group. CONCLUSIONS This close association found between plasma triacylglycerols, LDL-c, saturated fatty acids, polyunsaturated fatty acids, total amount of fatty acids and coenzyme Q(10) with some periodontal data such as periodontal probing depth, recession of the gingival margin and clinical attachment level (Pearson correlation between 0.3 and 0.6), leads to the conclusion that there is an inter-relationship between periodontitis, plasma fatty acids profile and the increase in metabolic risk factors for cardiovascular diseases.

Abstract
OBJECTIVE Fish oil has anti-inflammatory actions that may benefit periodontal health. We investigated the longitudinal relation between dietary ω-3 fatty acids (FAs), docosahexaenoic acid (DHA), and eicosapentaenoic acid (EPA) to periodontal disease in community-dwelling elderly. METHODS Fifty-five participants aged 74 y were randomly selected from a longitudinal interdisciplinary study of aging. Dietary intake data were obtained by a 3-d weighed food intake. The dietary intakes of energy, DHA, and EPA were calculated based on the Standard Food Composition Tables in Japan. Dental examinations were carried out at baseline and once a year for 5 y. The number of teeth with periodontal progression over 5 y per person was calculated as "periodontal disease events." Negative binomial regression analysis was conducted, which included DHA, EPA, and other covariates as independent variables to estimate the influence on periodontal disease events. Longitudinal data were analyzed for participants for whom data were available for 5 y (n=36). RESULTS Low DHA intake was significantly associated with more periodontal disease events. The mean number of periodontal disease events for participants who consumed the lowest tertile of DHA was approximately 1.5 times larger (lowest tertile, incidence rate ratio 1.49, 95% confidence interval 1.01-2.21) than the reference group (highest tertile of DHA consumption), after simultaneously adjusting for possible confounders. CONCLUSION The findings suggest there may be an inverse, independent relation of dietary DHA intake to the progression of periodontal disease in older people.

Abstract
Anti-inflammatory properties have been widely reported for n-3 polyunsaturated fatty acids (PUFAs) and some studies have been focalized on their possible role in the modulation of gingivitis and alveolar bone resorption in periodontal disease (PD). Increased formation of arachidonic acid-derived inflammatory eicosanoids and augmented oxidative stress are two molecular mechanisms pathogenetically involved in the progression of PD and known to be inhibited by n-3 PUFAs in PD setting. The present review will focus also on other molecular pathways and factors known to be altered in the development of PD and known to be subject to n-3 PUFA modulation in other pathological settings different from PD. Overall, the available findings strongly encourage further experimental studies on animals subject to experimental PD and treated with n-3 PUFAs, long term n-3 PUFA intervention studies on PD patients and molecular studies to identify additional potential molecular routes of n-3 PUFA action in PD.

Abstract
High-resolution 1H NMR spectroscopy as a complementary method in the analysis of human bone marrow fatty acid (FA) composition was examined. Marrow FA composition in 10 bone samples measured by NMR and gas chromatography (GC) were compared. NMR T1 relaxation time of FA was determined and reproducibility tests were performed to assess the variability. Good correlations were obtained between the NMR and GC results for omega-6 polyunsaturated fatty acid (PUFA) (Spearman r, 0.878), omega-3 PUFA (0.895), monounsaturated FA (0.964) and saturated FA (0.939). The NMR method tended to overestimate saturated FA and underestimate omega-3/omega-6 ratio compared to GC results. T1 relaxation time of marrow FA was 0.56-3.65s. Coefficient of variation of the NMR method was 0.6-8.2% in intra-experimental and 0.2-8.4% in inter-experimental measurements. This study demonstrates a complementary role for 1H NMR spectroscopy as an additional analytical tool in human lipid research.

Abstract
BACKGROUND The most recently described phenotype associated with Cystic Fibrosis (CF) is reduced bone mineral density which results in osteopenia and osteoporosis. The etiology of the early onset of osteoporosis in CF patients has remained to be established. It has been suggested that inadequate nutritional absorption of essential fatty acids may play a role in the altered bone metabolism. In this study, we characterized the protective effect of fenretinide [N-(4-hydroxyphenyl) retinamide], a vitamin A derivative, on the early onset of osteoporosis in cystic fibrosis transmembrane conductance regulator knockout (Cftr-KO) mice. METHODS Using micro-computed-tomography we examined the effect of fenretinide on the bone composition and architecture in a Cftr-KO mouse model which was then confirmed with histological analyses. Plasma fatty acids were quantified using thin layer chromatography-ELISA method. RESULTS Twice-weekly treatments with fenretinide, over four weeks dramatically increased trabecular bone volume compared to controls. This increase in bone volume was also related to an increased concentration of ceramide in the plasma resulting in the down regulation of phospholipid-bound AA in Cftr-KO mice. CONCLUSIONS To our knowledge, this is the first time that fenretinide's protective effect against osteoporosis has been demonstrated. The results of this study strongly suggest that fenretinide has potential to be used as a prophylaxis by preventing the early onset of osteoporosis.

Abstract
INTRODUCTION Porphyromonas gingivalis is strongly implicated in the etiology of adult periodontitis by inducing inflammatory cytokines, resulting in gingival and periodontal tissue inflammation and alveolar bone resorption. This study tested the hypothesis that supplementing the diet with omega-3 fatty acid (omega-3 FA; i.e. fish oil) would exert anti-inflammatory effects in the gingival tissues of P. gingivalis-infected rats. METHODS Rats were fed either fish oil or corn oil diets ad libitum for 22 weeks and infected with P. gingivalis strain 381 or strain A7A1-28. After sacrifice, rat gingival tissues were excised and the RNA was isolated and analyzed for proinflammatory mediators [interleukin-1beta (IL-1beta), tumor necrosis factor-alpha (TNF-alpha), IL-6], T helper type 1 and type 2 cytokines [interferon-gamma (IFN-gamma), IL-4, IL-10), antioxidant enzymes [catalase (CAT), superoxide dismutase (SOD)], and genes critical for eicosanoid mediator production [cyclo-oxygenase-2 (COX-2), 5-lipoxygenase (5-LO)] by reverse transcription-polymerase chain reaction using rat-specific primers. RESULTS Rats on the omega-3 FA diet exhibited decreased proinflammatory cytokine gene expression (IL-1beta, TNF-alpha) and enhanced IFN-gamma, CAT and SOD messenger RNA expression compared to rats fed a corn oil diet, supporting a diet-induced modulation of host inflammatory reactions. Analyses of alveolar bone resorption in the rats related to gene expression profiles demonstrated significant positive correlations with IL-1beta, IL-6 and COX-2 and negative correlations with CAT and SOD. CONCLUSION These findings suggest that diets enriched for omega-3 FA modulate the local gingival inflammatory milieu of the host following oral P. gingivalis infection, which impacts on alveolar bone resorption in rats.

Abstract
A consistent observation in osteoporosis is bone volume reduction accompanied by increased marrow adipose tissue. No single cause linking the two phenomena has yet been identified. In a human progenitor cell clone (hOP 7) derived from bone marrow, however, we have demonstrated that rabbit serum can direct differentiation away from an osteoblast lineage to one of adipocytes. We now report on whether human serum has a similar effect. Serum was collected from 10 pre- and 10 postmenopausal women and from the 10 postmenopausal women before and following 6-week hormone replacement therapy (HRT). hOP 7 cells were cultured with the various sera, and after 7-14 days adipocytogenesis was determined by oil red O staining and lipoprotein lipase (LPL) and glycerol 3-phosphate dehydrogenase (G3PDH) expression. Incubation with 10% premenopausal serum led to labeling of 10.9% of cells (P < 0.05) with oil red O, whereas application of 10% postmenopausal serum led to a much larger effect, 43.5% labeling (P < 0.001 with respect to premenopausal serum). Oil red O positivity was accompanied by loss of type I collagen expression and increased LPL and G3PDH expression. HRT did not reverse the adipocytogenic effect of postmenopausal serum. In conclusion, serum from postmenopausal women contains factors that steer hOP 7 bone progenitor cells toward an adipocytic phenotype, irrespective of HRT. The study suggests a role for serum factors in the development of fatty marrow in postmenopausal osteoporosis.

Abstract
Epidemic rates of osteoporosis in the western world have yielded intense efforts to develop management approaches to combat this potentially devastating disorder; recent research has unveiled innovative strategies which hold considerable promise for prevention of skeletal compromise and amelioration of suboptimal bone health. According to many algorithms and practice directives, the contemporary assessment and management of osteoporosis focuses heavily on determination of fracture risk and pharmaceutical intervention for those patients deemed to be at high risk. While routine recommendations for calcium and vitamin D have been incorporated into most regimens, disproportionately little attention has been given to recent research elucidating improved bone health and diminution in fracture rates experienced by patients receiving specific nutrients. In mainstream medical practice, clinical analysis and management of nutritional or dietary issues is sometimes perceived as unconventional, primitive or unsophisticated health care. Recent evidence-based research, however, supports intervention with adequate amounts of specific nutrients including vitamin D, strontium, vitamin K, and essential fatty acids in the prevention and primary management of osteoporosis.

Abstract
Gingival inflammation and alveolar bone resorption are hallmarks of adult periodontitis, elicited in response to oral micro-organisms such as Porphyromonas gingivalis. We hypothesized that omega (omega)-3 fatty acids (FA) dietary supplementation would modulate inflammatory reactions leading to periodontal disease in infected rats. Rats were fed fish oil (omega-3 FA) or corn oil (n-6 FA) diets for 22 weeks and were infected with P. gingivalis. Rats on the omega-3 FA diet exhibited elevated serum levels of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), documenting diet-induced changes. PCR analyses demonstrated that rats were orally colonized by P. gingivalis; increased IgG antibody levels substantiated this infection. P. gingivalis-infected rats treated with omega-3 FA had significantly less alveolar bone resorption. These results demonstrated the effectiveness of an omega-3 FA-supplemented diet in modulating alveolar bone resorption following P. gingivalis infection, and supported that omega-3 FA may be a useful adjunct in the treatment of periodontal disease.

Abstract
Life expectancy has increased considerably over the last century in the United States. It is expected that this longevity will be accompanied by an increase in the prevalence of osteoporosis and accompanying complications in the elderly population. Age-related loss of bone mass and bone fragility are major risk factors for osteoporosis, leading to an increased risk of fractures. Therefore, nutritional strategies and lifestyle changes that prevent age-related osteoporosis and improve the quality of life for the elderly population are urgently needed. Hence, the present study compared the effects of corn oil (CO; n-6 fatty acids; commonly present in Western diets) and fish oil (FO; n-3 fatty acids) on bone mineral density (BMD) in aging C57BL/6 female mice. After 6 months of dietary treatment, we found that 18-month-old FO-fed mice maintained higher BMD in different bone regions compared to CO-fed mice. These findings were accompanied by a decreased activity of pro-inflammatory cytokines, tumor necrosis factor-alpha and interleukin-6 in stimulated splenocytes; a nonsignificant but greater increase in bone formation markers alkaline phosphatase and osteocalcin in the serum; and lower osteoclast generation in bone marrow cell cultures in FO-fed mice. In conclusion, these findings suggest that providing n-3 fatty acids may have a beneficial effect on bone mass during aging by modulating bone formation and bone resorption factors.

Abstract
There has been little research examining the link between dietary fat intake and the symptoms and consequences of anorexia nervosa. In this selective literature review, the potential significance of poly-unsaturated fatty acids is discussed. It is hypothesised that dietary restriction causes essential fatty acid deficiencies and poly-unsaturated fatty acid abnormalities, which might contribute to the physical and mental symptoms and the maintenance of the disorder. The examination of epidemiology, symptoms, co-morbidity, and consequences suggest that poly-unsaturated fatty acid and phospholipid abnormalities are significant in anorexia nervosa. This will be an important area for future research, and may lead to the development of new interventions.

Abstract
BACKGROUND High alkaline phosphatase activity (ALP) is shown in the periodontal ligament due to the constant renewal of this tissue or pathological circumstances. We have previously shown that the activity level of this enzyme could be reflected at the serum level. OBJECTIVES Because the local production of ALP in the periodontal ligament is often of the bone-type enzyme, we studied the activity of this isozyme among the other isoforms in the serum of patients with chronic periodontitis in comparison with that of control subjects. MATERIAL AND METHODS This study included 83 patients (59 with periodontal disease, 24 as control group) and we determined the total seric ALP activity and the percentage of the different isoforms (essentially bone, kidney and intestinal-types) by Ektachem analyser and gel agarose electrophoresis respectively. CONCLUSIONS By comparisons between the two groups, our results showed a relationship between loss of attachment in periodontal disease and a drop in bone ALP activity in serum. Moreover, these results suggested a gender based difference as well, with lower activity more frequent in women than in men.

Abstract
Diabetes mellitus is a systemic disease with several major complications affecting both the quality and length of life. One of these complications is periodontal disease (periodontitis). Periodontitis is much more than a localized oral infection. Recent data indicate that periodontitis may cause changes in systemic physiology. The interrelationships between periodontitis and diabetes provide an example of systemic disease predisposing to oral infection, and once that infection is established, the oral infection exacerbates systemic disease. In this case, it may also be possible for the oral infection to predispose to systemic disease. In order to understand the cellular/molecular mechanisms responsible for such a cyclical association, one must identify common physiological changes associated with diabetes and periodontitis that produce a synergy when the conditions coexist. A potential mechanistic link involves the broad axis of inflammation, specifically immune cell phenotype, serum lipid levels, and tissue homeostasis. Diabetes-induced changes in immune cell function produce an inflammatory immune cell phenotype (upregulation of proinflammatory cytokines from monocytes/polymorphonuclear leukocytes and downregulation of growth factors from macrophages). This predisposes to chronic inflammation, progressive tissue breakdown, and diminished tissue repair capacity. Periodontal tissues frequently manifest these changes because they are constantly wounded by substances emanating from bacterial biofilms. Diabetic patients are prone to elevated low density lipoprotein cholesterol and triglycerides (LDL/TRG) even when blood glucose levels are well controlled. This is significant, as recent studies demonstrate that hyperlipidemia may be one of the factors associated with diabetes-induced immune cell alterations. Recent human studies have established a relationship between high serum lipid levels and periodontitis. Some evidence now suggests that periodontitis itself may lead to elevated LDL/TRG. Periodontitis-induced bacteremia/endotoxemia has been shown to cause elevations of serum proinflammatory cytokines such as interleukin-1 beta (IL-1 beta) and tumor necrosis factor-alpha (TNF-alpha), which have been demonstrated to produce alterations in lipid metabolism leading to hyperlipidemia. Within this context, periodontitis may contribute to elevated proinflammatory cytokines/serum lipids and potentially to systemic disease arising from chronic hyperlipidemia and/or increased inflammatory mediators. These cytokines can produce an insulin resistance syndrome similar to that observed in diabetes and initiate destruction of pancreatic beta cells leading to development of diabetes. Thus, there is potential for periodontitis to exacerbate diabetes-induced hyperlipidemia, immune cell alterations, and diminished tissue repair capacity. It may also be possible for chronic periodontitis to induce diabetes.
