    The study has been designed to investigate the effect of benfotiamine and fenofibrate in diabetes-induced experimental vascular endothelial dysfunction (VED) and nephropathy. The single administration of streptozotocin (STZ) (50 mg/kg, i.p.) produced diabetes, which was noted to develop VED and nephropathy in 8 weeks. The diabetes produced VED by attenuating acetylcholine-induced endothelium dependent relaxation, impairing the integrity of vascular endothelium, decreasing serum nitrite/nitrate concentration and increasing serum TBARS and aortic superoxide anion generation. Further, diabetes altered the lipid profile by increasing the serum cholesterol, triglycerides and decreasing the high density lipoprotein. The nephropathy was noted to be developed in the diabetic rat that was assessed in terms of increase in serum creatinine, blood urea, proteinuria, and glomerular damage. The benfotiamine (70 mg/kg, p.o.) and fenofibrate (32 mg/kg, p.o.) or lisinopril (1 mg/kg, p.o., a standard agent) treatments were started in diabetic rats after 1 week of STZ administration and continued for 7 weeks. The treatment with benfotiamine and fenofibrate either alone or in combination attenuated diabetes-induced VED and nephropathy. In addition, the combination of benfotiamine and fenofibrate was noted to be more effective in attenuating the diabetes-induced VED and nephropathy when compared to treatment with either drug alone or lisinopril. Treatment with fenofibrate normalizes the altered lipid profile in diabetic rats, whereas benfotiamine treatment has no effect on lipid alteration in diabetic rats. It may be concluded that diabetes-induced oxidative stress, lipids alteration, and consequent development of VED may be responsible for the induction of nephropathy in diabetic rats. Concurrent administration of benfotiamine and fenofibrate may provide synergistic benefits in preventing the development of diabetes-induced nephropathy by reducing the oxidative stress and lipid

    Chronic microglial activation and resulting sustained neuroinflammatory reaction are generally associated with neurodegeneration. Activated microglia acquires proinflammatory cellular profile that generates oxidative burst. Their persistent activation exacerbates inflammation, which damages healthy neurons via cytotoxic mediators, such as superoxide radical anion and nitric oxide. In our recent study, we have shown that benfotiamine (S-benzoylthiamine O-monophosphate) possesses anti-inflammatory effects. Here, the effects of benfotiamine on the pro-oxidative component of activity of LPS-stimulated BV-2 cells were investigated. The activation of microglia was accompanied by upregulation of intracellular antioxidative defense, which was further promoted in the presence of benfotiamine. Namely, activated microglia exposed to non-cytotoxic doses of benfotiamine showed increased levels and activities of hydrogen peroxide- and superoxide-removing enzymes-catalase and glutathione system, and superoxide dismutase. In addition, benfotiamine showed the capacity to directly scavenge superoxide radical anion. As a consequence, benfotiamine suppressed the activation of microglia and provoked a decrease in NO and (·)O(-) 2 production and lipid peroxidation. In conclusion, benfotiamine might silence pro-oxidative activity of microglia to alleviate/prevent oxidative damage of neighboring CNS cells.

    We investigated whether overexpression of catalase (CAT) in renal proximal tubular cells (RPTCs) could prevent the programming of hypertension and kidney disease in the offspring of dams with maternal diabetes. Male offspring of nondiabetic and diabetic dams from two transgenic (Tg) lines (Hoxb7-green fluorescent protein [GFP]-Tg [controls] and Hoxb7/CAT-GFP-Tg, which overexpress CAT in RPTCs) were studied from the prenatal period into adulthood. Nephrogenesis, systolic blood pressure, renal hyperfiltration, kidney injury, and reactive oxygen species (ROS) generation were assessed. Gene expression of transforming growth factor-β1 (TGF-β1), nuclear factor erythroid 2p45-related factor-2 (Nrf2), and heme oxygenase-1 (HO-1) was tested in both in vitro and in vivo studies. Renal dysmorphogenesis was observed in offspring of Hoxb7-GFP-Tg dams with severe maternal diabetes; the affected male offspring displayed higher renal ROS generation and developed hypertension and renal hyperfiltration as well as renal injury with heightened TGF-β1 expression in adulthood. These changes were ameliorated in male offspring of diabetic Hoxb7/CAT-GFP-Tg dams via the Nrf2-HO-1 defense system. CAT promoted Nrf2 nuclear translocation and HO-1 gene expression, seen in both in vitro and in vivo studies. In conclusion, CAT overexpression in the RPTCs ameliorated maternal diabetes-induced perinatal programming, mediated, at least in part, by triggering the Nrf2-HO-1 defense system.

    The present study has been designed to investigate the effect of benfotiamine, a thiamine derivative, in sodium arsenite-induced vascular endothelial dysfunction (VED) in rats. Sodium arsenite (1.5 mg(-1) kg(-1) day(-1) i.p., 2 weeks) was administered in rats to produce VED. The development of VED was assessed by employing isolated aortic ring preparation and estimating the serum and aortic concentrations of nitrite/nitrate. Further, the integrity of vascular endothelium in thoracic aorta was assessed by scanning electron microscopy. Moreover, the oxidative stress was assessed by estimating serum thiobarbituric acid reactive substances (TBARS) and aortic superoxide anion generation. The administration of sodium arsenite markedly produced VED by attenuating acetylcholine-induced endothelium-dependent relaxation, decreasing serum and aortic concentrations of nitrite/nitrate, and impairing the integrity of vascular endothelium. Further, sodium arsenite produced oxidative stress by increasing serum TBARS and aortic superoxide generation. The treatment with benfotiamine (25, 50, and 100 mg(-1) kg(-1) day(-1) p.o.) or atorvastatin (30 mg(-1) kg(-1) day(-1) p.o., a standard agent) prevented sodium arsenite-induced VED and oxidative stress. However, the beneficial effects of benfotiamine in preventing the sodium arsenite-induced VED were attenuated by co-administration with N-omega-nitro-L: -arginine methyl ester (L: -NAME) (25 mg(-1) kg(-1) day(-1), i.p.), an inhibitor of NOS. Thus, it may be concluded that benfotiamine reduces oxidative stress and activates endothelial nitric oxide synthase to enhance the generation and bioavailability of NO and subsequently improves the integrity of vascular endothelium to prevent sodium arsenite-induced experimental VED.

    Diabetic conditions are associated with modified brain function, namely with cognitive deficits, through largely undetermined processes. More than understanding the underlying mechanism, it is important to devise novel strategies to alleviate diabetes-induced cognitive deficits. Caffeine (a mixed antagonist of adenosine A(1) and A(2A) receptors) emerges as a promising candidate since caffeine consumption reduces the risk of diabetes and effectively prevents memory deficits caused by different noxious stimuli. Thus, we took advantage of a novel animal model of type 2 diabetes to investigate the behavioural, neurochemical and morphological modifications present in the hippocampus and tested if caffeine consumption might prevent these changes. We used a model closely mimicking the human type 2 diabetes condition, NONcNZO10/LtJ mice, which become diabetic at 7-11 months when kept under an 11% fat diet. Caffeine (1 g/l) was applied in the drinking water from 7 months onwards. Diabetic mice displayed a decreased spontaneous alternation in the Y-maze accompanied by a decreased density of nerve terminal markers (synaptophysin, SNAP25), mainly glutamatergic (vesicular glutamate transporters), and increased astrogliosis (GFAP immunoreactivity) compared to their wild type littermates kept under the same diet. Furthermore, diabetic mice displayed up-regulated A(2A) receptors and down-regulated A(1) receptors in the hippocampus. Caffeine consumption restored memory performance and abrogated the diabetes-induced loss of nerve terminals and astrogliosis. These results provide the first evidence that type 2 diabetic mice display a loss of nerve terminal markers and astrogliosis, which is associated with memory impairment; furthermore, caffeine consumption prevents synaptic dysfunction and astrogliosis as well as memory impairment in type 2 diabetes.

    Microglial cells are resident immune cells of the central nervous system (CNS), recognized as key elements in the regulation of neural homeostasis and the response to injury and repair. As excessive activation of microglia may lead to neurodegeneration, therapeutic strategies targeting its inhibition were shown to improve treatment of most neurodegenerative diseases. Benfotiamine is a synthetic vitamin B1 (thiamine) derivate exerting potentially anti-inflammatory effects. Despite the encouraging results regarding benfotiamine potential to alleviate diabetic microangiopathy, neuropathy and other oxidative stress-induced pathological conditions, its activities and cellular mechanisms during microglial activation have yet to be elucidated. In the present study, the anti-inflammatory effects of benfotiamine were investigated in lipopolysaccharide (LPS)-stimulated murine BV-2 microglia. We determined that benfotiamine remodels activated microglia to acquire the shape that is characteristic of non-stimulated BV-2 cells. In addition, benfotiamine significantly decreased production of pro-inflammatory mediators such as inducible form of nitric oxide synthase (iNOS) and NO; cyclooxygenase-2 (COX-2), heat-shock protein 70 (Hsp70), tumor necrosis factor alpha α (TNF-α), interleukin-6 (IL-6), whereas it increased anti-inflammatory interleukin-10 (IL-10) production in LPS stimulated BV-2 microglia. Moreover, benfotiamine suppressed the phosphorylation of extracellular signal-regulated kinases 1/2 (ERK1/2), c-Jun N-terminal kinases (JNK) and protein kinase B Akt/PKB. Treatment with specific inhibitors revealed that benfotiamine-mediated suppression of NO production was via JNK1/2 and Akt pathway, while the cytokine suppression includes ERK1/2, JNK1/2 and Akt pathways. Finally, the potentially protective effect is mediated by the suppression of translocation of nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) in the nucleus. Therefore, benfotiamine may

    The study has been designed to investigate the effect of benfotiamine, a thiamine derivative, in nicotine and uric acid-induced vascular endothelial dysfunction (VED) in rats. Nicotine (2 mg kg(-1)day(-1), i.p., 4 weeks) and uric acid (150 mg kg(-1)day(-1), i.p., 3 weeks) were administered to produce VED in rats. The development of VED was assessed by employing isolated aortic ring preparation and estimating serum and aortic concentration of nitrite/nitrate. Further, the integrity of vascular endothelium was assessed using the scanning electron microscopy (SEM) of thoracic aorta. Moreover, the oxidative stress was assessed by estimating serum thiobarbituric acid reactive substances (TBARS) and aortic superoxide anion generation. The administration of nicotine and uric acid produced VED by impairing the integrity of vascular endothelium and subsequently decreasing serum and aortic concentration of nitrite/nitrate and attenuating acetylcholine-induced endothelium dependent relaxation. Further, nicotine and uric acid produced oxidative stress, which was assessed in terms of increase in serum TBARS and aortic superoxide generation. However, treatment with benfotiamine (70 mg kg(-1)day(-1), p.o.) or atorvastatin (30 mg kg(-1)day(-1) p.o., a standard agent) markedly prevented nicotine and uric acid-induced VED and oxidative stress by improving the integrity of vascular endothelium, increasing the concentration of serum and aortic nitrite/nitrate, enhancing the acetylcholine-induced endothelium dependent relaxation and decreasing serum TBARS and aortic superoxide anion generation. Thus, it may be concluded that benfotiamine reduces the oxidative stress and consequently improves the integrity of vascular endothelium and enhances the generation of nitric oxide to prevent nicotine and uric acid-induced experimental VED.

    Full Text Available Abstract Background Oxidative stress plays an important role in diabetes-induced vascular inflammation and pathogenesis. Nuclear factor E2-related factor-2 (Nrf2 is a transcription factor orchestrating antioxidant and cyto-protective responses to oxidative stress. In the present study, we tested whether sulforaphane (SFN can protect the aorta from diabetes and, if so, whether the aortic protection is associated with up-regulation of Nrf2 and its down-stream antioxidants. Methods Type 1 diabetes was induced in FVB mice by multiple low-dose streptozotocin. Diabetic and age-matched control mice were treated with or without SFN at 0.5 mg/kg daily in five days of each week for three months. At the end of 3 months treatment of SFN one set of mice were sacrificed to perform the experimental measurements. The second set of both diabetic and control mice were aged for additional 3 months without further SFN treatment and then sacrificed to perform the experimental measurements. Aortas from these mice were assessed for fibrosis, inflammation, oxidative damage, and Nrf2 expression and transcription by immunohistochemical staining and real-time PCR method, respectively. Results Diabetes induced significant increases in oxidative stress and inflammation in the aorta at both 3 and 6 months, and fibrotic response at 6 months. SFN completely prevented these diabetic pathogenic changes and also significantly up-regulated the expression of Nrf2 and its down-stream antioxidants. Conclusions These results suggest that diabetes-induced aortic fibrosis, inflammation, and oxidative damage can be prevented by SFN. The aortic protection from diabetes by SFN was associated with the up-regulation of Nrf2 and its downstream antioxidants.

    Benfotiamine is a lipid-soluble thiamine precursor which can transform to thiamine in vivo and subsequently be metabolized to thiamine monophosphate (TMP) and thiamine diphosphate (TDP). This study investigated the pharmacokinetic profiles of thiamine and its phosphorylated metabolites after single- and multiple-dose administration of benfotiamine in healthy Chinese volunteers, and assessed the bioavailability of orally benfotiamine administration compared to thiamine hydrochloride. In addition, concentration of hippuric acid in urine which is produced in the transformation process of benfotiamine was determined. The results showed that thiamine and its phosphorylated metabolites exhibited different pharmacokinetic characteristics in plasma, blood and erythrocyte, and one-compartment model provided the best fit for pharmacokinetic profiles of thiamine. The transformation process of benfotiamine to thiamine produced large amount of hippuric acid. No accumulation of hippuric acid was observed after multiple-dose of benfotiamine. Compared to thiamine hydrochloride, the bioavailability of thiamine in plasma and TDP in erythrocyte after oral administration of benfotiamine were 1147.3 ± 490.3% and 195.8 ± 33.8%, respectively. The absorption rate and extent of benfotiamine systemic availability of thiamine were significantly increased indicating higher bioavailability of thiamine from oral dose of benfotiamine compared to oral dose of thiamine hydrochloride.

    Catalase is an antioxidant enzyme that specifically catabolizes hydrogen peroxide (H2O2). Overexpression of catalase via a heart-specific promoter (CAT-TG) was reported to reduce diabetes-induced accumulation of reactive oxygen species (ROS) and further prevent diabetes-induced pathological abnormalities, including cardiac structural derangement and left ventricular abnormity in mice. However, the mechanism by which catalase overexpression protects heart function remains unclear. This study found that activation of a ROS-dependent NF-κB signaling pathway was downregulated in hearts of diabetic mice overexpressing catalase. In addition, catalase overexpression inhibited the significant increase in nitration levels of key enzymes involved in energy metabolism, including α-oxoglutarate dehydrogenase E1 component (α-KGD) and ATP synthase α and β subunits (ATP-α and ATP-β). To assess the effects of the NF-κB pathway activation on heart function, Bay11-7082, an inhibitor of the NF-κB signaling pathway, was injected into diabetic mice, protecting mice against the development of cardiac damage and increased nitrative modifications of key enzymes involved in energy metabolism. In conclusion, these findings demonstrated that catalase protects mouse hearts against diabetic cardiomyopathy, partially by suppressing NF-κB-dependent inflammatory responses and associated protein nitration.

    Whether zinc is able to improve diabetes-induced liver injury remains unknown. Transgenic type 1 diabetic (OVE26) mice develop hyperglycemia at 3 weeks old; therefore therapeutic effect of zinc on diabetes-induced liver injury was investigated in OVE26 mice. Three-month old OVE26 and age-matched wild-type mice were treated by gavage with saline or zinc at 5mg/kg body-weight every other day for 3 months. Hepatic injury was examined by serum alanine aminotransferase (ALT) level with liver histopathological and biochemical changes. OVE26 mice at 6 months old showed significant increases in serum ALT level and hepatic oxidative damage, endoplasmic reticulum stress and associated cell death, mild inflammation, and fibrosis. However, all these hepatic morphological and functional changes were significantly prevented in 3-month zinc-treated OVE26 mice. Mechanistically, zinc treatment significantly increased hepatic metallothionein, a protein with known antioxidant activity, in both wild-type and OVE26 mice. These results suggest that there were significantly functional, structural and biochemical abnormalities in the liver of OVE26 diabetic mice at 6 months old; however, all these changes could be prevented with zinc treatment, which was associated with the upregulation of hepatic metallothionein expression.

    Full Text Available Background:In peritoneal dialysis (PD residual renal function (RRF fundamentally contributes to improved quality of life and patient survival. High glucose and advanced glycation end-products (AGE contribute locally to peritoneal and systemically to renal damage. Integrity of podocyte structure and function is of special importance to preserve RRF. Benfotiamine could counteract the glucose and AGE mediated toxicity by blocking hyperglycemia associated podocyte damage via the pentose phosphate pathway.Methods: A human differentiated podocyte cell line was incubated with control solution (Control, 2.5% glucose solution (Glucose and 2.5% PD fluid (PDF for 48 h either ± 50 μM benfotiamine.Podocyte damage and potential benefit of benfotiamine were analyzed using immunofluorescence, western blot analysis, and a functional migration assay. For quantitation, a semiquantitative score was used. Results:When incubating podocytes with benfotiamine, Glucose and PDF mediated damage was reduced resulting in lower expression of AGE and intact podocin and ZO-1 localization. The reorganization of the actin cytoskeleton was restored in the presence of benfotiamine as functional podocyte motility reached Control level. Decreased level of inflammation could be shown as well as reduced podocyte apoptosis.Conclusions:These data suggest that benfotiamine protects podocytes from Glucose and PDF mediated dysfunction and damage, in particular with regard to cytoskeletal reorganization, motility, inflammation and podocyte survival.

    Despite the presence of a multitudinous pharmacotherapy, diabetes-induced depressive disorder remains undertreated. Evidence suggests that brain serotonergic deficits are associated with depressive-like behavior in diabetes and that 5HT3 receptor (5HT3R) antagonists have serotonergic facilitatory effects. This study examined the effects of a novel 5HT3R antagonist, 4i (N-(3-chloro-2-methylphenyl)quinoxalin-2-carboxamide), in diabetes-induced depressive phenotypes. Experimentally, (1) to evaluate the effects of 4i, mice with 8-weeks of diabetes (induced by streptozotocin, 200mg/kg, i.p.) were treated with vehicle, 4i (0.5 and 1mg/kg/day, i.p.), fluoxetine (10mg/kg/day, i.p.) for 4-weeks and subjected to neurobehavioral assays, followed by biochemical estimation of serotonin levels in midbrain, prefrontal-cortex and cerebellum. (2) To evaluate the role of 5HT3R in the postulated effect of 4i, diabetic mice were given 4i (1mg/kg/day, i.p.) after 1h of 1-(m-chlorophenyl)-biguanide (mCPBG, a 5HT3R agonist, 10mg/kg/day, i.p.) treatment and subjected to the same protocol. The results showed that diabetic mice exhibited a significant behavioral deficit, including depression-like behavior in forced swim test, anxiety-like in open field test and sociability deficits in social interaction test, along with a significant decrease in serotonin level in these brain regions. 4i (1mg/kg), similar to fluoxetine, prevented these behavioral abnormalities and normalized brain serotonin levels. 4i (0.5mg/kg) ameliorated only diabetes-induced depressive-like behavior and serotonin deficits, but not anxiety-like effects. mCPBG blunted 4i-mediated behavioral response and increase in brain serotonin levels. Altogether, this study suggests that 4i prevents diabetes-induced depressive phenotypes in mice, which may involve antagonism of 5HT3Rs and increase in serotonin levels in discrete brain regions.

    A novel method was developed for spectral resolution and further determination of five-component mixture including Vitamin B complex (B1, B6, B12 and Benfotiamine) along with the commonly co-formulated Diclofenac. The method is simple, sensitive, precise and could efficiently determine the five components by a complementary application of two different techniques. The first is univariate second derivative method that was successfully applied for determination of Vitamin B12. The second is Multivariate Curve Resolution using the Alternating Least Squares method (MCR-ALS) by which an efficient resolution and quantitation of the quaternary spectrally overlapped Vitamin B1, Vitamin B6, Benfotiamine and Diclofenac sodium were achieved. The effect of different constraints was studied and the correlation between the true spectra and the estimated spectral profiles were found to be 0.9998, 0.9983, 0.9993 and 0.9933 for B1, B6, Benfotiamine and Diclofenac, respectively. All components were successfully determined in tablets and capsules and the results were compared to HPLC methods and they were found to be statistically non-significant.

    Full Text Available Vascular complications are the leading cause of morbidity and mortality in patients with diabetes. Quercetin is an important flavonoid with antioxidant and anti-inflammatory activity. Here, the effect of quercetin on diabetes-induced exaggerated vasoconstriction in insulin deficient and insulin resistant rat models was investigated. Insulin deficiency was induced by streptozotocin while, insulin resistance by fructose. Rats were left 8 weeks or 12 weeks after STZ or fructose administration respectively. Quercetin was daily administered in the last 6 weeks. Then, tail blood pressure (BP was recorded in conscious animals; concentration-response curves for phenylephrine (PE and KCl were studied in thoracic aorta rings. Non-fasting blood glucose level, serum insulin level, insulin resistance index, serum tumour necrosis factor-α (TNF-α and serum C-reactive protein (CRP were determined. Nuclear transcription factor-κB (NF-κB was assessed by immunofluorescence technique. Histopathological examination was also performed. The results showed that quercetin protected against diabetes-induced exaggerated vasoconstriction and reduced the elevated blood pressure. In addition, quercetin inhibited diabetes associated adventitial leukocyte infiltration, endothelial pyknosis and increased collagen deposition. These effects were accompanied with reduction in serum level of both TNF-α and CRP and inhibition of aortic NF-κB by quercetin in both models of diabetes. On the other hand, quercetin did not affect glucose level in any of the used diabetic models. This suggests that the protective effect of quercetin is mediated by its anti-inflammatory effect rather than its metabolic effects. In summary, quercetin is potential candidate to prevent diabetic vascular complications in both insulin deficiency and resistance via its inhibitory effect on inflammatory pathways especially NF-κB signaling.

    Objective Daily application of far-red light from the onset of diabetes mitigated diabetes-induced abnormalities in retinas of albino rats. Here, we test the hypothesis that photobiomodulation (PBM) is effective in diabetic, pigmented mice, even when delayed until weeks after onset of diabetes. Direct and indirect effects of PBM on the retina also were studied. Methods Diabetes was induced in C57Bl/6J mice using streptozotocin. Some diabetics were exposed to PBM therapy (4 min/day; 670 nm) daily. In one study, mice were diabetic for 4 weeks before initiation of PBM for an additional 10 weeks. Retinal oxidative stress, inflammation, and retinal function were measured. In some mice, heads were covered with a lead shield during PBM to prevent direct illumination of the eye, or animals were treated with an inhibitor of heme oxygenase-1. In a second study, PBM was initiated immediately after onset of diabetes, and administered daily for 2 months. These mice were examined using manganese-enhanced MRI to assess effects of PBM on transretinal calcium channel function in vivo. Results PBM intervention improved diabetes-induced changes in superoxide generation, leukostasis, expression of ICAM-1, and visual performance. PBM acted in part remotely from the retina because the beneficial effects were achieved even with the head shielded from the light therapy, and because leukocyte-mediated cytotoxicity of retinal endothelial cells was less in diabetics treated with PBM. SnPP+PBM significantly reduced iNOS expression compared to PBM alone, but significantly exacerbated leukostasis. In study 2, PBM largely mitigated diabetes-induced retinal calcium channel dysfunction in all retinal layers. Conclusions PBM induces retinal protection against abnormalities induced by diabetes in pigmented animals, and even as an intervention. Beneficial effects on the retina likely are mediated by both direct and indirect mechanisms. PBM is a novel non-pharmacologic treatment strategy to inhibit

    Full Text Available Diabetes mellitus has been reported to affect functions of the hippocampus. We hypothesized that Centella asiatica, a herb traditionally being used to improve memory, prevents diabetes-related hippocampal dysfunction. Therefore, the aim of this study was to investigate the protective role of C. asiatica on the hippocampus in diabetes. Methods. Streptozotocin- (STZ- induced adult male diabetic rats received 100 and 200 mg/kg/day body weight (b.w C. asiatica leaf aqueous extract for four consecutive weeks. Following sacrifice, hippocampus was removed and hippocampal tissue homogenates were analyzed for Na+/K+-, Ca2+- and Mg2+-ATPases activity levels. Levels of the markers of inflammation (tumor necrosis factor, TNF-α; interleukin, IL-6; and interleukin, IL-1β and oxidative stress (lipid peroxidation product: LPO, superoxide dismutase: SOD, catalase: CAT, and glutathione peroxidase: GPx were determined. The hippocampal sections were visualized for histopathological changes. Results. Administration of C. asiatica leaf aqueous extract to diabetic rats maintained near normal ATPases activity levels and prevents the increase in the levels of inflammatory and oxidative stress markers in the hippocampus. Lesser signs of histopathological changes were observed in the hippocampus of C. asiatica leaf aqueous extract treated diabetic rats. Conclusions. C. asiatica leaf protects the hippocampus against diabetes-induced dysfunction which could help to preserve memory in this condition.

Methods. The rats were divided into: (1 Control, (2 Diabetic, (3 Diabetic-Extract 100 (Dia-Ext 100, (4 Diabetic-Extract 200 (Dia-Ext 200, (5 Diabetic-Extract 400 (Dia-Ext 400, and (6 Diabetic-Metformin (Dia-Met. Groups 3–6 were treated by 100, 200, and 400 mg/kg of the extract or metformin, respectively, for 6 weeks (orally. Results. In passive avoidance test, the latency to enter the dark compartment in Diabetic group was lower than that of Control group (P<0.01. In Dia-Ext 100, Dia-Ext 200, and Dia-Ext 400 and Metformin groups, the latencies were higher than those of Diabetic group (P<0.01. Lipid peroxides levels (reported as malondialdehyde, MDA, concentration in the brain of Diabetic group were higher than Control (P<0.001. Treatment by all doses of the extract and metformin decreased the MDA concentration (P<0.01. Conclusions. The results of present study showed that metformin and the hydroalcoholic extract of Teucrium polium prevent diabetes-induced memory deficits in rats. Protection against brain tissues oxidative damage might have a role in the beneficial effects of the extract and metformin.

    Molecular mechanisms of the beneficial effects of angiotensin-(1-7), Ang-(1-7), in diabetes-related complications, including erectile dysfunction, remain unclear. We examined the effect of diabetes and/or Ang-(1-7) treatment on vascular reactivity and cyclic guanosine monophosphate (cGMP) phosphodiesterase (PDE) in corpus cavernosum. Male Wistar rats were grouped as (1) control, (2) diabetic (streptozotocin, STZ, treated), (3) control + Ang-(1-7), and (4) diabetic + Ang-(1-7). Following 3 weeks of Ang-(1-7) treatment subsequent to induction of diabetes, rats were sacrificed. Penile cavernosal tissue was isolated to measure vascular reactivity, PDE gene expression and activity, and levels of p38MAP kinase, nitrites, and cGMP. Carbachol-induced vasorelaxant response after preincubation of corpus cavernosum with PE was significantly attenuated in diabetic rats, and Ang-(1-7) markedly corrected the diabetes-induced impairment. Gene expression and activity of PDE and p38MAP kinase were significantly increased in cavernosal tissue of diabetic rats, and Ang-(1-7) markedly attenuated STZ-induced effects. Ang-(1-7) significantly increased the levels of nitrite and cGMP in cavernosal tissue of control and diabetic rats. Cavernosal tissue of diabetic rats had significantly reduced cGMP levels and Ang-(1-7) markedly prevented the STZ-induced cGMP depletion. This study demonstrates that attenuation of diabetes-induced PDE activity might be one of the key mechanisms in the beneficial effects of Ang-(1-7).

    The epidermal growth factor receptors, EGFR and EGFR2 (ErbB2), appear important mediators of diabetes-induced vascular dysfunction. We investigated whether targeted dual inhibition of EGFR and ErbB2 with Lapatinib would be effective in treating diabetes-induced vascular dysfunction in a rat model of type 1 diabetes. In streptozotocin-induced diabetes, chronic 4-week oral or acute, ex vivo, administration of Lapatinib prevented the development of vascular dysfunction as indicated by the attenuation of the hyper-reactivity of the diabetic mesenteric vascular bed (MVB) to norephinephrine without correcting hyperglycemia. Chronic in vivo or acute ex vivo Lapatinib treatment also significantly attenuated diabetes-induced increases in phosphorylation of EGFR, ErbB2, ERK1/2, AKT, ROCK2 and IkB-alpha as well as normalized the reduced levels of phosphorylated FOXO3A, and eNOS (Ser1177) in the diabetic MVB. Similar results were observed in vascular smooth muscle cells (VSMCs) cultured in high glucose (25 mM) treated with Lapatinib or small interfering RNA (siRNA) targeting the ErbB2 receptor. Lapatinib also prevented high glucose-induced apoptosis in VSMC. Thus, Lapatinib corrects hyperglycemia-induced apoptosis and vascular dysfunction with concomitant reversal of diabetes or high glucose-induced signaling changes in EGFR/ErbB2 and downstream signaling pathways implying that targeted dual inhibition of EGFR/ErbB2 might be an effective vasculoprotective treatment strategy in diabetic patients.

    Neuropathy will afflict over half of the approximately 350 million people worldwide who currently suffer from diabetes and around one-third of diabetic patients with neuropathy will suffer from painful symptoms that may be spontaneous or stimulus evoked. Diabetes can be induced in rats or mice by genetic, dietary, or chemical means, and there are a variety of well-characterized models of diabetic neuropathy that replicate either type 1 or type 2 diabetes. Diabetic rodents display aspects of sensorimotor dysfunction such as stimulus-evoked allodynia and hyperalgesia that are widely used to model painful neuropathy. This allows investigation of pathogenic mechanisms and development of potential therapeutic interventions that may alleviate established pain or prevent onset of pain.

    Full Text Available We aim to investigate the effects of curcumin on preventing diabetes-induced vascular inflammation in association with its actions on Txnip, ICAM-1, and NOX2 enzyme expressions. Male Wistar rats were divided into four groups: control (CON, diabetic (DM; streptozotocin (STZ, i.v. 55 mg/kg BW, control-treated with curcumin (CONCUR; 300 mg/kg BW, and diabetes treated with curcumin (DMCUR; 300 mg/kg BW. 12th week after STZ injection, iris blood perfusion, leukocyte adhesion, Txnip, p47phox, and malondialdehyde (MDA levels were determined by using laser Doppler, intravital fluorescent confocal microscopy, Western Blot analysis, and TBAR assay, respectively. The iris blood perfusion of DM and DMCUR was decreased significantly compared to CON and CONCUR (P<0.001. Plasma glucose and HbA1c of DM and DMCUR were increased significantly compared to CON and CONCUR (P<0.001. Leukocyte adhesion, ICAM-1, p47phox expression, and MDA levels in DM were increased significantly compared to CON, CONCUR, and DMCUR (P<0.05. Txnip expression in DM and DMCUR was significantly higher than CON and CONCUR (P<0.05. From Pearson’s analysis, the correlation between the plasma MDA level and the endothelial functions was significant. It suggested that curcumin could ameliorate diabetic vascular inflammation by decreasing ROS overproduction, reducing leukocyte-endothelium interaction, and inhibiting ICAM-1 and NOX2 expression.

    This study investigated the effects of flaxseed (Linum usitatissimum L.) intake on general metabolism, pentose phosphate pathway (PPP) and glutathione-dependent enzymes in diabetic rats. Diabetes was induced by streptozotocin injection (40 mg/kg, i.p.) and the enzyme activities were determined spectrophotometrically. Diabetic and control rats were divided in two subgroups, one untreated, and one treated with flaxseed (0.714 g/kg body weight/day; orally) for 12 weeks. Flaxseed ameliorated decreased body weight (p < .05) and increased blood glucose (p < .001), triglyceride (p < .001), ALT (p < .001) and AST (p < .001) in diabetic rats. Diabetes resulted in increased glucose-6-phosphate dehydrogenase (G6PD) (p < .05) and decreased glutathione-S-transferase (GST) (p < .01), but unchanged 6-phosphogluconate dehydrogenase (6PGD) and glutathione reductase (GR) in the brain of rats. These alterations were partially improved by flaxseed in comparison to diabetic untreated group (p < .05). G6PD, 6PGD, GR were elevated (p < .001), while GST unchanged in the lung of diabetic untreated group compared to control. Flaxseed partially prevented the increase in 6PGD (p < .05) and GR (p < .01), but unaffected G6PD in the lung of diabetic rats. G6PD (p < .001), 6PGD (p < .05), GR (p < .001) were augmented, while GST showed a significant (p < .001) depletion in the pancreas of diabetic untreated rats compared to control. Diabetic alterations observed in pancreatic enzyme activities were significantly prevented by flaxseed. Furthermore, a remarkable decrease in 6PGD (p < .001) and an increase in G6PD (threefold of control) were found in the lens of diabetic untreated group that were completely prevented by flaxseed (p < .001). Flaxseed has beneficial effects against diabetes-induced glucotoxicity by modulating G6PD, 6PGD, GR and GST activities in tissues.

    Full Text Available BACKGROUND: Lipotoxicity is a key feature of the pathogenesis of diabetic kidney disease, and is attributed to excessive lipid accumulation (hyperlipidemia. Increasing evidence suggests that fibroblast growth factor (FGF21 has a crucial role in lipid metabolism under diabetic conditions. OBJECTIVE: The present study investigated whether FGF21 can prevent hyperlipidemia- or diabetes-induced renal damage, and if so, the possible mechanism. METHODS: Mice were injected with free fatty acids (FFAs, 10 mg/10 g body weight or streptozotocin (150 mg/kg to establish a lipotoxic model or type 1 diabetic model, respectively. Simultaneously the mice were treated with FGF21 (100 µg/kg for 10 or 80 days. The kidney weight-to-tibia length ratio and renal function were assessed. Systematic and renal lipid levels were detected by ELISA and Oil Red O staining. Renal apoptosis was examined by TUNEL assay. Inflammation, oxidative stress, and fibrosis were assessed by Western blot. RESULTS: Acute FFA administration and chronic diabetes were associated with lower kidney-to-tibia length ratio, higher lipid levels, severe renal apoptosis and renal dysfunction. Obvious inflammation, oxidative stress and fibrosis also observed in the kidney of both mice models. Deletion of the fgf21 gene further enhanced the above pathological changes, which were significantly prevented by administration of exogenous FGF21. CONCLUSION: These results suggest that FFA administration and diabetes induced renal damage, which was further enhanced in FGF21 knock-out mice. Administration of FGF21 significantly prevented both FFA- and diabetes-induced renal damage partially by decreasing renal lipid accumulation and suppressing inflammation, oxidative stress, and fibrosis.

    Abnormalities in lysosomal function have been reported in diabetes, aging, and age-related degenerative diseases. These lysosomal abnormalities are an early manifestation of neurodegenerative diseases and often precede the onset of clinical symptoms such as learning and memory deficits; however, the mechanism underlying lysosomal dysfunction is not known. In the current study, we investigated the mechanism underlying lysosomal dysfunction in the cortex and hippocampi, key structures involved in learning and memory, of a type 2 diabetes (T2D) mouse model, the leptin receptor deficient db/db mouse. We demonstrate for the first time that diabetes leads to destabilization of lysosomes as well as alterations in the protein expression, activity, and/or trafficking of two lysosomal enzymes, hexosaminidase A and cathepsin D, in the hippocampus of db/db mice. Pioglitazone, a thiazolidinedione (TZD) commonly used in the treatment of diabetes due to its ability to improve insulin sensitivity and reverse hyperglycemia, was ineffective in reversing the diabetes-induced changes on lysosomal enzymes. Our previous work revealed that pioglitazone does not reverse hypercholesterolemia; thus, we investigated whether cholesterol plays a role in diabetes-induced lysosomal changes. In vitro, cholesterol promoted the destabilization of lysosomes, suggesting that lysosomal-related changes associated with diabetes are due to elevated levels of cholesterol. Since lysosome dysfunction precedes neurodegeneration, cognitive deficits, and Alzheimer's disease neuropathology, our results may provide a potential mechanism that links diabetes with complications of the central nervous system.

    Diabetes-induced glutathione (GSH) decrease is usually ascribed to GSH oxidation. Here we investigate, in streptozotocin-treated rats, if impairment of GSH synthesis contributes to GSH decrease in diabetic liver, and if antioxidant treatments can provide protection. Diabetic rats were divided into 3 groups: untreated diabetic rats (UD); N-acetyl-cysteine (NAC)-treated diabetic rats; taurine (TAU)-treated diabetic rats; a group of non-streptozotocin-treated rats was used as control (CTR). All rats were sacrificed at 40 weeks of age. Diabetes induced hepatic glutathione decrease, but oxidized glutathione (GSSG) did not increase significantly. Accumulations of cysteine and cysteinyl-glycine in UD suggest respectively decreased glutathione synthesis and increased loss through the plasma membrane with subsequent degradation. Decreased expression of γ-glutamyl-cysteine synthetase in UD is consistent with repressed GSH synthesis. Moreover, diabetes caused increase of GSSG/GSH ratio and induction of heme oxygenase-1, both signs of oxidative stress. Supplementation with NAC or TAU resulted in amelioration of glutathione levels, probably depending on antioxidant activity, more efficient glutathione synthesis and decreased GSH loss and degradation. In conclusion, impaired synthesis and increased loss and degradation of GSH appear to contribute to a decrease in GSH levels in diabetic liver. NAC and TAU are able to partially protect from oxidative stress and GSH decrease, while enhancing GSH synthesis and restricting GSH loss.

    Diabetes-induced testicular apoptosis is predominantly due to increased oxidative stress. The nuclear factor-erythroid 2-related factor 2 (Nrf2), as a master transcription factor in controlling anti-oxidative systems, is able to be induced by sulforaphane (SFN). To examine whether SFN prevents testicular apoptosis, type 1 diabetic mouse model was induced with multiple low-dose streptozotocin. Diabetic and age-matched control mice were treated with and without SFN at 0.5 mg/kg daily in five days of each week for 3 months and then kept until 6 months. Diabetes significantly increased testicular apoptosis that was associated with endoplasmic reticulum stress and mitochondrial cell death pathways, shown by the increased expression of C/EBP homologous protein (CHOP), cleaved caspase-12, Bax to Bcl2 expression ratio, and cleaved caspase-3. Diabetes also significantly increased testicular oxidative damage, inflammation and fibrosis, and decreased germ cell proliferation. All these diabetic effects were significantly prevented by SFN treatment for the first 3 months, and the protective effect could be sustained at 3 months after SFN treatment. SFN was able to up-regulate Nrf2 expression and function. The latter was reflected by the increased phosphorylation of Nrf2 at Ser40 and expression of Nrf2 downstream antioxidants at mRNA and protein levels. These results suggest that type 1 diabetes significantly induced testicular apoptosis and damage along with increasing oxidative stress and cell death and suppressing Nrf2 expression and function. SFN is able to prevent testicular oxidative damage and apoptosis in type 1 diabetes mice, which may be associated with the preservation of testicular Nrf2 expression and function under diabetic condition. - Highlights: • Sulforaphane (SFN) could attenuate diabetes-induced germ cell apoptosis. • SFN could preserve germ cell proliferation under diabetic conditions. • SFN testicular protection was sustained until 3 months after

    Background Quail eggs as a food item have recently been introduced into the diet of some Cameroonians. These eggs are being sold in local markets, but with many unfounded health claims. One claim is that quail eggs can reduce blood glucose levels in diabetics. It was therefore necessary to evaluate the effect of consuming quail eggs on blood glucose levels, lipid profiles, and oxidative stress parameters in diabetes-induced rats. Methods Twenty Wistar rats weighing, on average, 250 g were divided into four groups of five rats each. Group 1 consisted of rats with normal blood glucose, and the other three groups (2, 3, and 4) consisted of diabetes-induced rats achieved by intravenous injection of streptozotocin. During 16 days, rats in groups 1 and 2 received distilled water; and rats in groups 3 and 4 received quail and chicken eggs, respectively, with gastroesophageal probe at a dose of 1 mL/200 g body weight. Fasting blood glucose levels were determined in all the groups on the 1st, 7th, 14th, and 17th days after induction of diabetes. On the 17th day, the fasting rats were sacrificed, and blood and liver samples were collected for biochemical analyses. Results In 17 days, the consumption of quail and chicken eggs had no effect on blood glucose levels of diabetic rats. Total cholesterol levels were higher in groups 3 (75.59 mg/dL) and 4 (59.41 mg/dL) compared to group 2 (55.67 mg/dl), although these differences were not significant (all p>0.05). Triglyceride levels were significantly higher (pdiabetic rats at the tested dose had no effect on blood glucose level and oxidative stress parameters and may have a negative effect on lipid profile.

    Full Text Available Abstract A common complication associated with diabetes is painful or painless diabetic peripheral neuropathy (DPN. The mechanisms and determinants responsible for these peripheral neuropathies are poorly understood. Using both streptozotocin (STZ-induced and transgene-mediated murine models of type 1 diabetes (T1D, we demonstrate that Transient Receptor Potential Vanilloid 1 (TRPV1 expression varies with the neuropathic phenotype. We have found that both STZ- and transgene-mediated T1D are associated with two distinct phases of thermal pain sensitivity that parallel changes in TRPV1 as determined by paw withdrawal latency (PWL. An early phase of hyperalgesia and a late phase of hypoalgesia are evident. TRPV1-mediated whole cell currents are larger and smaller in dorsal root ganglion (DRG neurons collected from hyperalgesic and hypoalgesic mice. Resiniferatoxin (RTX binding, a measure of TRPV1 expression is increased and decreased in DRG and paw skin of hyperalgesic and hypoalgesic mice, respectively. Immunohistochemical labeling of spinal cord lamina I and II, dorsal root ganglion (DRG, and paw skin from hyperalgesic and hypoalgesic mice reveal increased and decreased TRPV1 expression, respectively. A role for TRPV1 in thermal DPN is further suggested by the failure of STZ treatment to influence thermal nociception in TRPV1 deficient mice. These findings demonstrate that altered TRPV1 expression and function contribute to diabetes-induced changes in thermal perception.

    The hypothesis of fetal origins of adult disease states that early life events program the occurrence of significant adult diseases, including diabetes and obesity. Maternal diabetes is associated with general stress environment for developing fetus, and gestational diabetes is an independent risk factor for type 2 diabetes and metabolic syndrome in offspring. Intra-uterine fetal programming of fetal tissues exposes the offspring to increased risk of impaired glucose tolerance, type 2 diabetes, and cardiovascular disease. Here, we examined the transmission of maternal diabetes-induced fetal programming in second generation and compared maternal and paternal routes of intergenerational effects. We organized 40 Wistar rats into three groups, male offspring of diabetic mothers, female offspring of diabetic mothers, and offspring of control mothers. These groups were mated with normal healthy rats to assess the effect of grand-maternal diabetes on pregnancy outcome in F2 rats, as well as glucose-sensing parameters, insulin resistance, and glucose tolerance prenatally and postnatally. We found that F2 offspring of diabetic mothers had impaired glucose sensing, increased oxidative stress, insulin resistance, and impaired glucose tolerance, and these effects were more prominent in the F2 offspring of F1 female rats (F2-DF1F). We deduce that fetal programming of maternal diabetes is mostly transmitted through maternal line across two generations.

    Objective The beneficial effects of silymarin have been extensively studied in the context of inflammation and cancer treatment, yet much less is known about its therapeutic effect on diabetes. The present study was aimed to investigate the cytoprotective activity of silymarin against diabetes-induced cardiomyocyte apoptosis. Methods Rats were randomly divided into: control group, untreated diabetes group and diabetes group treated with silymarin (120 mg/kg·d) for 10 d. Rats were sacrificed, and the cardiac muscle specimens and blood samples were collected. The immunoreactivity of caspase-3 and Bcl-2 in the cardiomyocytes was measured. Total proteins, glucose, insulin, creatinine, AST, ALT, cholesterol, and triglycerides levels were estimated. Results Unlike the treated diabetes group, cardiomyocyte apoptosis increased in the untreated rats, as evidenced by enhanced caspase-3 and declined Bcl-2 activities. The levels of glucose, creatinine, AST, ALT, cholesterol, and triglycerides declined in the treated rats. The declined levels of insulin were enhanced again after treatment of diabetic rats with silymarin, reflecting a restoration of the pancreaticβ-cells activity. Conclusion The findings of this study are of great importance, which confirmed for the first time that treatment of diabetic subjects with silymarin may protect cardiomyocytes against apoptosis and promote survival-restoration of the pancreaticβ-cells.

    Biomarkers are highly specific and sensitive indicators of disease activity. Resistin is a recently discovered adipocytokine, having a potent biomarker quality. Initially resistin was thought to be produced by adipocytes alone; however, emerging evidence suggests that it is also produced in abundance by various cells of the immunoinflammatory system, indicating its role in various chronic inflammatory diseases. Data suggests that resistin plays a role in obesity, insulin resistance, cardiovascular diseases, and periodontitis. Resistin derived its name from the original observation that it induced insulin resistance (resist-in: resist insulin) in mice and is downregulated in mature murine adipocytes cultured in the presence of insulin sensitizing drugs like thiazolidinediones. It is well recognized that obesity, is associated with insulin resistance and diabetes. A three-way relationship has been established between diabetes, obesity and periodontitis. Recent evidence also suggests an association between obesity and increased risk for periodontitis. Our previous research showed incremental elevation of resistin with periodontal disease activity and a reduced level of resistin, after periodontal therapy. Thus resistin would be one of the molecular links connecting obesity, periodontitis, and diabetes and may serve as a marker that links periodontal disease with other systemic diseases. A Medline/PubMed search was carried out for keywords "Diabetes Mellitus," "Periodontitis," and "Resistin," and all relevant research papers from 1990 in English were shortlisted and finalized based on their importance. This review provides an insight into the biological action of resistin and its possible role in periodontitis influenced diabetes mellitus and diabetes induced periodontitis.

    2010-01-01

    Full Text Available Endothelial dysfunction is characterized by reduced bioavailability of NO due to its inactivation to form peroxynitrite or reduced expression of eNOS. Here, we examine the causal role of peroxynitrite in mediating diabetes-induced endothelial dysfunction. Diabetes was induced by STZ-injection, and rats received the peroxynitrite decomposition catalyst (FeTTPs, 15 mg/Kg/day for 4 weeks. Vasorelaxation to acetylcholine, oxidative-stress markers, RhoA activity, and eNOS expression were determined. Diabetic coronary arteries showed significant reduction in ACh-mediated maximal relaxation compared to controls. Diabetic vessels showed also significant increases in lipid-peroxides, nitrotyrosine, and active RhoA and 50% reduction in eNOS mRNA expression. Treatment of diabetic animals with FeTTPS blocked these effects. Studies in aortic endothelial cells show that high glucose or peroxynitrite increases the active RhoA kinase levels and decreases eNOS expression and NO levels, which were reversed with blocking peroxynitrite or Rho kinase. Together, peroxynitrite can suppress eNOS expression via activation of RhoA and hence cause vascular dysfunction.

    This study aimed to investigate whether treatments with vitamin E, L-carnitine and melatonin can protect against CCl(4) and diabetes-induced hepatic oxidative stress. Hepatic oxidative stress was performed in rats through 50% v/v carbon tetrachloride (CCl(4)) (1 ml/kg/3 days, i.p.), and through diabetes mellitus induced by streptozotocin (STZ) (40 mg/kg, i.p.). Vitamin E (100 mg/kg/day, i.p), L-carnitine (300 mg/kg/day, i.p.) and melatonin (10 mg/kg/day, i.p.) were injected for a period of 6 weeks. Thereafter, changes in serum glucose level, liver function tests, hepatic malondialdehyde (MDA) content, hepatic reduced glutathione (GSH) content, hepatic superoxide dismutase (SOD) activity, and serum total antioxidant capacity (TAC) level were evaluated. In CCl(4)-induced liver fibrosis, the efficacy order was melatonin > L-carnitine > vitamin E, while in STZ-induced diabetes, the efficacy order was vitamin E > or = melatonin > L-carnitine. In conclusion, these data indicate that low dose of melatonin is more effective than high doses of vitamin E and L-carnitine in reducing hepatic oxidative stress induced by CCl(4) and diabetes. Moreover, the potent effect of vitamin E in ameliorating diabetes can be linked not only to the antioxidant actions, but also to the superior effect in reducing diabetes-induced hyperglycaemia. Meanwhile, potency of L-carnitine was nearly the same in CCl(4) and diabetes-induced liver damage.

    Full Text Available Objective(s:Painful diabetic neuropathy is associated with hyperexcitability and hyperactivity of spinal cord neurons. However, its underlying pathophysiological mechanisms have not been fully clarified. Induction of excitatory/inhibitory neurotransmission imbalance at the spinal cord seems to account for the abnormal neuronal activity in diabetes. Protective properties of neurosteroids have been demonstrated in numerous cellular and animal models of neurodegeneration. Materials and Methods: Here, the protective effects of allopregnanolone, a neurosteroid were investigated in an in vivo model of diabetic neuropathy. The tail-flick test was used to assess the nociceptive threshold. Diabetes was induced by injection of 50 mg/kg (IP streptozotocin. Seven weeks after the induction of diabetes, the dorsal half of the lumbar spinal cord was assayed for the expression of γ2 subunit of GABAA receptor using semiquantitative RT-PCR. Results: The data shows that allopregnanolone (5 and 20 mg/kg markedly ameliorated diabetes-induced thermal hyperalgesia and motor deficit. The weights of diabetic rats that received 5 and 20 mg/kg allopregnanolone did not significantly reduce during the time course of study. Furthermore, this neurosteroid could inhibit GABAA receptor down-regulation induced by diabetes in the rat spinal cord. Conclusion: The data revealed that allopregnanolone has preventive effects against hyperglycemic-induced neuropathic pain and motor deficit which are related to the inhibition of GABAA receptor down-regulation.

    Insulin-dependent diabetes mellitus (type 1 diabetes) is an inflammatory autoimmune disease associated with vascular permeability changes leading to many complications including nephropathy, retinopathy, neuropathy, hypertension and hyperalgesia. The bradykinin B(1) receptors (BKB(1)-R) were recently found to be upregulated alongside the development of type 1 diabetes and to be involved in its complications. Kinins are important mediators of a variety of biological effects including cardiovascular homeostasis, inflammation and nociception. In the present study, we studied the effect of a selective BKB(1)-R agonist desArg(9)-BK (DBK) and two selective receptor antagonists, the R-715 (Ac-Lys-[D-beta Nal(7), Ile(8)] desArg(9)-BK) and the R-954 (Ac-Orn-[Oic(2), alphaMe Phe(5), D-beta Nal(7), Ile(8)] desArg(9)-BK) on diabetic hyperalgesia. Type 1 diabetes was induced in male CD-1 mice via a single injection of streptozotocin (STZ, 200mg/kg, i.p.), one week before the test. Nociception, a measure of hyperalgesia, was assessed using the plantar stimulation (Hargreaves) and the tail-immersion tests. The induction of type 1 diabetes provoked a significant hyperalgesic activity in diabetic mice, causing an 11% decrease in plantar stimulation reaction time and 13% decrease in tail-immersion reaction time, compared to normal mice. Following acute administration of R-715 (100-600 microg/kg, i.p.), or R-954 (50-400 microg/kg, i.p.), the STZ-induced hyperalgesic activity was blocked in a dose-dependent manner and the hot plate and tail-immersion latencies of diabetic mice returned to normal values observed in control healthy mice. In addition, the acute administration of DBK (400 microg/kg, i.p.) significantly potentiated diabetes-induced hyperalgesia, an effect that was totally reversed by R-715 (1.6-2.4 mg/kg, i.p.) and R-954 (0.8-1.2mg/kg, i.p.). These results provide further evidence for the implication of the BKB(1)-R in type 1 diabetic hyperalgesia and suggest a novel

    Full Text Available Abstract Background Congenital heart defects are frequently observed in infants of diabetic mothers, but the molecular basis of the defects remains obscure. Thus, the present study was performed to gain some insights into the molecular pathogenesis of maternal diabetes-induced congenital heart defects in mice. Methods and results We analyzed the morphological changes, the expression pattern of some genes, the proliferation index and apoptosis in developing heart of embryos at E13.5 from streptozotocin-induced diabetic mice. Morphological analysis has shown the persistent truncus arteriosus combined with a ventricular septal defect in embryos of diabetic mice. Several other defects including defective endocardial cushion (EC and aberrant myofibrillogenesis have also been found. Cardiac neural crest defects in experimental embryos were analyzed and validated by the protein expression of NCAM and PGP 9.5. In addition, the protein expression of Bmp4, Msx1 and Pax3 involved in the development of cardiac neural crest was found to be reduced in the defective hearts. The mRNA expression of Bmp4, Msx1 and Pax3 was significantly down-regulated (p p p Conclusion It is suggested that the down-regulation of genes involved in development of cardiac neural crest could contribute to the pathogenesis of maternal diabetes-induced congenital heart defects.

    Full Text Available Purpose: Ethanol extract of Clitorea ternatea (EECT was evaluated in diabetes-induced cognitive decline rat model for its nootropic and neuroprotective activity. Materials and Methods: Effect on spatial working memory, spatial reference memory and spatial working-reference memory was evaluated by Y maze, Morris water maze and Radial arm maze respectively. Neuroprotective effects of EECT was studied by assaying acetylcholinesterase, lipid peroxide, superoxide dismutase (SOD, total nitric oxide (NO, catalase (CAT and glutathione (GSH levels in the brain of diabetic rats. Results: The EECT (200 and 400 mg/kg was found to cause significant increase in spatial working memory ( P < 0.05, spatial reference memory ( P < 0.001 and spatial working-reference ( P < 0.001 in retention trials on Y maze, Morris water maze and Radial arm maze respectively. Whereas significant decrease in acetylcholinesterase activity ( P < 0.05, lipid peroxide ( P < 0.001, total NO ( P < 0.001 and significant increase in SOD, CAT and GSH levels was observed in animals treated with EECT (200 and 400 mg/kg compared to diabetic control group. Conclusions: The present data indicates that Clitorea ternatea tenders protection against diabetes induced cognitive decline and merits the need for further studies to elucidate its mode of action.

    Male reproductive dysfunctions and infertility are the common consequences of overt diabetes. Available evidence support oxidative stress to be the underlying mechanism for the manifestation of testicular complications during diabetes. In the present study, we assessed the attenuating effects of Withania somnifera root extract (WS) on diabetes-induced testicular oxidative disturbances in prepubertal rats. Four-week-old prepubertal rats were assigned into nondiabetic control, streptozotocin (STZ)-treated and STZ+WS supplemented (500 mg/kg b.w./d, oral, 15 days) groups. Experimental diabetes was induced by a single intraperitoneal injection of STZ (90 mg/kg b.w). Terminally, all animals were killed, and markers of oxidative stress were determined in the testis cytosol and mitochondrial fraction. Severe hyperglycemia and regression in testis size were apparent in diabetic rats. A decline in antioxidant defenses with subsequent elevation in the generation of reactive oxygen species and lipid peroxidation was discernible in testis cytosol and mitochondria of diabetic prepubertal rats, which was significantly reversed by WS. However, there was partial restoration of glucose-6-phosphate dehydrogenase, lactate dehydrogenase, and 3-beta hydroxysteroid dehydrogenase activities in testis of diabetic prepubertal rats administered with WS. Taken together, data accrued suggest the potential of WS to improve diabetes-induced testicular dysfunctions in prepubertal rats.

    Diabetes can lead to dysfunction of the secretory capacity in salivary glands. Activation of the receptor for advanced glycation end products (RAGE) and its ligands has been suggested to participate in chronic disorders such as diabetes and its complications. In this study, the expression of RAGE, high mobility group box 1 (HMGB1) and advanced glycation end products (AGE), as well as the effects of low-power laser irradiation (LPLI) in salivary glands of diabetic rats were evaluated, and the mechanisms involved were characterized. The expression of RAGE and HMGB1 at the protein and mRNA levels was observed in submandibular glands (SMGs) of streptozotocin-induced diabetic rats. A diode laser was applied at 660 nm, 70 mW, 20 J/cm2, 0.56 J/point, with a spot area of 0.028 cm2 and its in vivo effects and the pathways involved were evaluated. Immunohistochemistry and western blotting analysis were performed for inflammatory and apoptosis markers. Diabetes up-regulates HMGB1/AGE/RAGE axis gene expression in SMGs that is associated with activation of the nuclear factor kappa B (NF-κB) pathway. Interestingly, LPLI suppresses NF-κB activation induced by inflammation. LPLI also reduces diabetes-induced apoptosis. That effect was accompanied by decreased levels of Bax, and cleaved caspase 3, which were up-regulated in diabetes. Taken together, our data suggest that LPLI reduces diabetes-induced inflammation by reducing the induction of HMGB1, ultimately leading to inhibition of apoptosis in submandibular glands of diabetic rats.

    We have previously shown that the low-dose combination of fenofibrate and rosiglitazone might halt the progression of diabetes-induced nephropathy in rats. The present study investigated the combined effect of fenofibrate (PPARα agonist) and telmisartan (AT₁ receptor antagonist) in diabetes-induced onset of nephropathy in rats. The single administration of streptozotocin (STZ, 55 mg/kg i.p.) produced diabetes mellitus, which subsequently produced nephropathy in 8 weeks by markedly elevating serum creatinine, blood urea nitrogen and microproteinuria. In addition, histopathological studies revealed the development of renal structural abnormalities such as mesangial expansion, glomerular and tubular damage. Moreover, diabetes-induced nephropathy was accompanied with high renal oxidative stress and lipid alteration. Treatment with fenofibrate (80 mg/kg/day, p.o., 4 weeks) and telmisartan (10 mg/kg/day, p.o., 4 weeks) either alone or in combination did not affect the elevated glucose levels in diabetic rats. Albeit treatment with fenofibrate normalizes the altered lipid profile in diabetic rats, telmisartan treatment has no effect on it. Treatment with fenofibrate and telmisartan either alone or in combination markedly prevented diabetes-induced onset of nephropathy and renal oxidative stress. Their combination was as good as to their individual treatment, but not superior in attenuating the diabetes-induced nephropathy and renal oxidative stress. It may be concluded that diabetes-induced oxidative stress and lipid alteration, besides hyperglycemia, could play a key role in the induction of nephropathy. Fenofibrate and telmisartan individual treatment was equipotent in preventing the onset of diabetes-induced experimental nephropathy, while their combination did not afford additional benefits in preventing the disease induction of the diabetic kidney.

    Full Text Available Diabetic retinopathy is a leading cause of reduced visual acuity and acquired blindness. Axoglial alterations of the distal (close to the chiasm optic nerve (ON could be the first structural change of the visual pathway in streptozotocin (STZ-induced diabetes in rats. We analyzed the effect of environmental enrichment on axoglial alterations of the ON provoked by experimental diabetes. For this purpose, three days after vehicle or STZ injection, animals were housed in enriched environment (EE or remained in a standard environment (SE for 6 weeks. Anterograde transport, retinal morphology, optic nerve axons (toluidine blue staining and phosphorylated neurofilament heavy immunoreactivity, microglia/macrophages (ionized calcium binding adaptor molecule 1 (Iba-1 immunoreactivity, astrocyte reactivity (glial fibrillary acid protein-immunostaining, myelin (myelin basic protein immunoreactivity, ultrastructure, and brain derived neurotrophic factor (BDNF levels were assessed in non-diabetic and diabetic animals housed in SE or EE. No differences in retinal morphology or retinal ganglion cell number were observed among groups. EE housing which did not affect the STZ-induced weight loss and hyperglycemia, prevented a decrease in the anterograde transport from the retina to the superior colliculus, ON axon number, and phosphorylated neurofilament heavy immunoreactivity. Moreover, EE housing prevented an increase in Iba-1 immunoreactivity, and astrocyte reactivity, as well as ultrastructural myelin alterations in the ON distal portion at early stages of diabetes. In addition, EE housing avoided a decrease in BDNF levels induced by experimental diabetes. These results suggest that EE induced neuroprotection in the diabetic visual pathway.

    Diabetes associated hyperglycemia results in generation of reactive oxygen species which induces oxidative stress and initiate massive DNA damage leading to overactivation of poly (ADP-ribose) polymerase (PARP). In this study, we have elucidated the involvement of oxidative stress-PARP pathway using pharmacological interventions (melatonin, as an anti-oxidant and nicotinamide, as a PARP inhibitor) in diabetes-induced neurobehavioral and neurochemical alterations. Sprague-Dawley rats were rendered diabetic by a single intraperitoneal injection of streptozotocin. Behavioral and cognitive deficits were assessed after 8weeks of diabetes induction using a functional observation battery, passive avoidance and rotarod test. Acetylcholinesterase activity was significantly decreased in hippocampus of diabetic rats as compared to control rats. Diabetic animals showed significant increase in malondialdehyde levels and reduction in NAD levels in hippocampus. Glutamate and GABA levels were also altered in hippocampus of the diabetic animals. Two week treatment with melatonin (3 and 10mg/kg) and nicotinamide (300 and 1000mg/kg) alone and in combination significantly improved the neurobehavioral parameters which were altered in diabetes. Neurotransmitter (glutamate and GABA) levels were improved by these interventions. Our results emphasize that simultaneous inhibition of oxidative stress-PARP overactivation cascade can be beneficial in treatment of diabetes associated CNS changes.

    The present study was designed to evaluate the effect of Vitamin E (Vit. E) on diabetes-induced changes in small intestine, lipid peroxidation and plasma antioxidant capacity in rats. Twenty-four rats were divided into three groups (n=8), namely control, non-treated diabetic (NTD) and Vit. E-treated diabetic (VETD) groups. The VETD group received 300 mg of Vit. E daily in drinking water. After 6 weeks, the length and weight of small intestine, villus height, crypt depth and muscular layer thickness showed a significant increase in the NTD group compared to the control group. In the VETD group, these parameters did not show any significant difference compared to the control group. The level of malondialdehyde (MDA) in the red blood cells showed a significant increase in the NTD group, but not in the VETD group, compared to the control group. The plasma antioxidant capacity showed a significant increase in VETD compared to the NTD group. These findings indicate that Vit. E significantly improved small intestinal changes in diabetic rats and that these effects could be mediated at least in part by enhanced plasma antioxidant capacity and reduced lipid peroxidation.

    Cognitive impairment occurs in diabetes mellitus. Hypericum perforatum has been used in folk medicine to improve mental performance. Here it is hypothesized that chronic treatment with an extract of Hypericum perforatum (6, 12 and 25 mg/kg, p.o.) would have effects on passive avoidance learning (PAL) and memory in control and streptozotocin-induced diabetic rats. Treatments were begun at the onset of hyperglycaemia. PAL was assessed 30 days later. A retention test was done 24 h after training. At the end, the animals were weighed and blood samples were drawn for plasma glucose measurement. Diabetes caused impairment in acquisition and retrieval processes of PAL and memory. Hypericum treatment (12 and 25 mg/kg) improved learning and memory in control rats and reversed learning and memory deficits in diabetic rats. A dose of 6 mg/kg did not affect cognitive function. Hypericum administration did not alter the body weight and plasma glucose levels. Antioxidant properties and cholinergic facilitatory effects of Hypericum may be involved in its nootropic effects. These results show that Hypericum perforatum prevented the deleterious effects of diabetes on PAL and memory. As Hypericum would be free of major side effects compared with other nootropic medications, it may provide a new potential alternative for demented diabetic patients.

    Diabetes mellitus is a chronic metabolic disorder with a high prevalence worldwide. Animal models of diabetes represent an important tool in diabetes investigation that helps us to avoid unnecessary and ethically challenging studies in human subjects, as well as to obtain a comprehensive scientific viewpoint of this disease. Although there are several methods through which diabetes can be induced, chemical methods of alloxan- and streptozotocin-induced diabetes represent the most important and highly preferable experimental models for this pathological condition. Therefore, the aim of this article was to review the current knowledge related to quoted models of diabetes, including to this point available information about mechanism of action, particular time- and dose-dependent protocols, frequent problems, as well as major limitations linked to laboratory application of alloxan and sterptozotocin in inducing diabetes. Given that diabetes is known to be closely associated with serious health consequences it is of fundamental importance that current animal models for induction of diabetes should be continuously upgraded in order to improve overall prevention, diagnosis and treatment of this pathological condition.

    Diabetic cardiomyopathy (DCM) is a significant contributor to the morbidity and mortality associated with diabetes and metabolic syndrome. Retinoids, through activation of retinoic acid receptor (RAR) and retinoid x receptor (RXR), have been linked to control glucose and lipid homeostasis, with effects on obesity and diabetes. However, the functional role of RAR and RXR in the development of DCM remains unclear. Zucker diabetic fatty (ZDF) and lean rats were treated with Am580 (RARα agonist) or LGD1069 (RXR agonist) for 16 weeks, and cardiac function and metabolic alterations were determined. Hyperglycemia, hyperlipidemia and insulin resistance were observed in ZDF rats. Diabetic cardiomyopathy was characterized in ZDF rats by increased oxidative stress, apoptosis, fibrosis, inflammation, activation of MAP kinases and NF-κB signaling and diminished Akt phosphorylation, along with decreased glucose transport and increased cardiac lipid accumulation, and ultimately diastolic dysfunction. Am580 and LGD1069 attenuated diabetes-induced cardiac dysfunction and the pathological alterations, by improving glucose tolerance and insulin resistance; facilitating Akt activation and glucose utilization, and attenuating oxidative stress and interrelated MAP kinase and NF-κB signaling pathways. Am580 inhibited body weight gain, attenuated the increased cardiac fatty acid uptake, β-oxidation and lipid accumulation in the hearts of ZDF rats. However, LGD1069 promoted body weight gain, hyperlipidemia and cardiac lipid accumulation. In conclusion, our data suggest that activation of RAR and RXR may have therapeutic potential in the treatment of diabetic cardiomyopathy. However, further studies are necessary to clarify the role of RAR and RXR in the regulation of lipid metabolism and homeostasis.

    The authors assessed effects of essential fatty acid deficiency (EFAD) on regional {sup 131}I-albumin permeation in diabetic and age-matched control rats. Male, Sprague-Dawley rats (50-75 g) were randomized into EFAD diet or normal diet groups. Three months later, diabetes was induced in one half of the rats in each group by injecting i.v. 35-45 mg/kg b.w. streptozotocin. One month later, {sup 131}I-albumin clearance ({mu} g plasma/g tissue/minute) was assessed as described previously (Circ Res 64;890, 1989). Within controls, EFAD decreased body weight gain 28% but did not affect control values for plasma glucose (118{plus minus}8 (SD) mg/dl) or glycosylated hemoglobin (1.33{plus minus}0.22 % of total hemoglobin). In normal diet and EFAD diabetics, plasma glucose (535{plus minus}64 and 419{plus minus}161, respectively) and glycosylated hemoglobin (4.38{plus minus}0.97 and 2.97{plus minus}1.69) were increased significantly versus controls. Diabetes increased {sup 131}I-albumin clearance in retinal (5.1x controls), choroid (3.4x), anterior uvea (2.7x), aorta (3.5x), and sciatic nerve (2.2x). No differences were evident in tissue {sup 131}I-albumin clearances between both control groups or both diabetic groups. These results suggest that essential fatty acids do not modulate diabetes-induced changes in endothelial cell barrier function.

    Diabetic nephropathy is a complex disease that involves increased production of free radicals which is a strong stimulus for the release of pro-inflammatory factors. We evaluated the renal protective effect of kolaviron (KV) - a Garcinia kola seed extract containing a mixture of 5 flavonoids, in diabetes-induced nephrotoxic rats. Male Wistar rats were divided into 4 groups: untreated controls (C); normal rats treated with kolaviron (C+KV); untreated diabetic rats (D); kolaviron treated diabetic rats (D+KV). A single intraperitoneal injection of streptozotocin (STZ, 50mg/kg) was used for the induction of diabetes. Renal function parameters were estimated in a clinical chemistry analyzer. Markers of oxidative stress in the kidney homogenate were analyzed in a Multiskan Spectrum plate reader and Bio-plex Promagnetic bead-based assays was used for the analysis of inflammatory markers. The effect of kolaviron on diabetes-induced apoptosis was assessed by TUNEL assay. In the diabetic rats, alterations in antioxidant defenses such as an increase in lipid peroxidation, glutathione peroxidase (GPX) activity and a decrease in catalase (CAT) activity, glutathione (GSH) levels and oxygen radical absorbance capacity (ORAC) were observed. There was no difference in superoxide dismutase (SOD) activity. Diabetes induction increased apoptotic cell death and the levels of interleukin (IL)-1β and tumor necrosis factor (TNF)-α with no effect on IL-10. Kolaviron treatment of diabetic rats restored the activities of antioxidant enzymes, reduced lipid peroxidation and increased ORAC and GSH concentration in renal tissues. Kolaviron treatment of diabetic rats also suppressed renal IL-1β. The beneficial effects of kolaviron on diabetes-induced kidney injury may be due to its inhibitory action on oxidative stress, IL-1β production and apoptosis.

    Chronic hyperglycemia is associated with impairment of testicular function. The current study aimed to investigate the protective effects and the possible mechanisms of taurine and pioglitazone against diabetes-induced testicular dysfunction in rats. Diabetes was induced by streptozotocin injection. Both normal and diabetic rats received taurine (100 mg/kg) or pioglitazone (10 mg/kg) orally and daily for 6 weeks. Diabetic rats showed a significant (P inflammatory cytokines. Serum insulin, testosterone, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) were significantly (P diabetic rats. Taurine and pioglitazone alleviated hyperglycemia, decreased pro-inflammatory cytokines, and increased circulating levels of insulin, testosterone, LH, and FSH. Gene and protein expression of LH and FSH receptors and cytochrome P450 17α-hydroxylase (CYP17) was significantly (P diabetic rats, an effect which was significantly increased after administration of taurine and pioglitazone. In addition, taurine and pioglitazone significantly decreased lipid peroxidation and DNA damage, and enhanced activity of the antioxidant enzymes in testes of diabetic rats. In conclusion, taurine and pioglitazone exerted protective effects against diabetes-induced testicular damage through attenuation of hyperglycemia, inflammation, oxidative stress and DNA damage, and up-regulation of the pituitary/gonadal axis.

    Diabetes is associated with behavioural and neurochemical alterations. In this manuscript, we are reporting the beneficial effects of parthenolide, an NF-κB inhibitor on behavioural and neurochemical deficits in type 2 diabetic rat model. Diabetes was induced by high-fat diet followed by low dose of streptozotocin (35 mg/kg). Elevated plus maze, open-field, MWM and passive avoidance test paradigm were used to assess behavioural and cognitive deficits. Three-week treatment of parthenolide (0.25 and 0.50 mg/kg; i.p.) attenuated diabetes-induced alteration in cognitive function in Morris water maze and passive avoidance test. Anxiety-like behaviour was also reduced by parthenolide treatment. Moreover, TNF-α and IL-6 levels were significantly decreased in cortex and hippocampus of parthenolide-treated rats. Three-week parthenolide treatment also toned down the alteration of GABA and glutamate homoeostasis. Results of this study corroborate the involvement of neuroinflammation in the development of behavioural and neurochemical deficits in diabetic animals and point towards the therapeutic potential of parthenolide in diabetes-induced alteration of learning, memory and anxiety behaviour.

    Sera from diabetic patients or sera with high levels of diabetic metabolic products, were found to affect mouse and rat blastocysts. In the present study we examined the earliest developmental stages at which human diabetic serum will be lethal to mouse pre-implantation embryos, and whether reactive oxygen species (ROS) are involved in these diabetes-induced injuries. We cultured 2-4 cell-stage embryos and blastocysts in a medium containing 30 or 50% serum obtained from pregnant women with diabetes Type I, Type II and gestational diabetes (GDM) for 72 h. The development of the 2-4 cell-stage embryos was delayed when cultured in 30% diabetic serum, but the viability was impaired to a lesser extent. Viability was reduced in blastocysts cultured in 50% diabetic serum, but the development of the living embryos was not delayed. Cyclic voltametry measures the oxidation potential of the tissue and the concentration of antioxidants, thus reflecting the total antioxidative activity of the embryos. Pre-implantation embryos cultured in diabetic serum had a lower concentration of antioxidants than embryos cultured in non-diabetic serum. It seems, therefore, that diabetic metabolic factors may induce embryotoxicity in pre-implantation embryos through derangement of the antioxidant defense mechanism. A similar mechanism is suggested for the diabetes-induced teratogenicity in post-implantation embryos.

    We hypothesized that administration of the superoxide dismutase (SOD) mimetic Tempol (4-hydroxy-2, 2, 6, 6-tetramethylpiperidine 1-oxyl) may reverse diabetes induced ED(erectile dysfunction). To test this hypothesis, ROS related genes (SOD1, SOD2, GPx1, CAT, NOS2, NOS3), erectile functional studies, and immunohistochemical analysis were performed in diabetic rats treated with or without Tempol. Thirty Sprague-Dawley (3–4 months old) rats were divided into 3 groups (n=10 each), 20 with diabetes (diabetic control and Tempol treatment) and 10 healthy controls. Twelve weeks after induction of diabetes by streptozotocin and Tempol treatment, all groups underwent in vivo cavernous nerve stimulation. Rat crura were harvested and expression of antioxidative defense enzymes examined by semi-quantitative RT-PCR. To confirm the RT-PCR results, we performed immunohistochemistry (IHC) for catalase (CAT) and iNOS (NOS2). Nitration of tyrosine groups in proteins was also examined by IHC. Mean intracavernous pressure in the diabetic group was significantly lower than in healthy controls (p<0.001) and was reversed by Tempol treatment (p<0.0108). NOS2 protein expression was significantly increased in diabetic animals compared to healthy controls and Tempol restored NOS2 protein level. Nitrotyrosine was also higher in diabetic animals and though Tempol treatment decreased its formation, it remained higher than that found in healthy controls. This study suggests that Tempol treatment increased erectile function through modulating oxidative stress related genes in diabetic rats. This is the first report about the relationship between diabetes induced erectile dysfunction and oxidative stress, and anti-oxidative therapy using the superoxide dismutase mimetic, Tempol to restore erectile function.

    Mitochondrial aldehyde dehydrogenase (ALDH2) is known to offer myocardial protection against stress conditions including ischemia-reperfusion injury, alcoholism and diabetes mellitus although the precise mechanism is unclear. This study was designed to evaluate the effect of ALDH2 on diabetes-induced myocardial injury with a focus on autophagy. Wild-type FVB and ALDH2 transgenic mice were challenged with streptozotozin (STZ, 200mg/kg, i.p.) for 3months to induce experimental diabetic cardiomyopathy. Diabetes triggered cardiac remodeling and contractile dysfunction as evidenced by cardiac hypertrophy, decreased cell shortening and prolonged relengthening duration, the effects of which were mitigated by ALDH2. Lectin staining displayed that diabetes promoted cardiac hypertrophy, the effect of which was alleviated by ALDH2. Western blot analysis revealed dampened autophagy protein markers including LC3B ratio and Atg7 along with upregulated p62 following experimental diabetes, the effect of which was reconciled by ALDH2. Phosphorylation level of AMPK was decreased and its downstream signaling molecule FOXO3a was upregulated in both diabetic cardiac tissue and in H9C2 cells with high glucose exposure. All these effect were partly abolished by ALDH2 overexpression and ALDH2 agonist Alda1. High glucose challenge dampened autophagy in H9C2 cells as evidenced by enhanced p62 levels and decreased levels of Atg7 and LC3B, the effect of which was alleviated by the ALDH2 activator Alda-1. High glucose-induced cell death and apoptosis were reversed by Alda-1. The autophagy inhibitor 3-MA and the AMPK inhibitor compound C mitigated Alda-1-offered beneficial effect whereas the autophagy inducer rapamycin mimicked or exacerbated high glucose-induced cell injury. Moreover, compound C nullified Alda-1-induced protection against STZ-induced changes in autophagy and function. Our results suggested that ALDH2 protects against diabetes-induced myocardial dysfunction possibly through an

    We hypothesized that in vitro treatment of peripheral blood mononuclear cells (PB-MNCs) from diabetic patients with ephrin-B2/Fc (EFNB2) improves their proangiogenic therapeutic potential in diabetic ischemic experimental models. Diabetes was induced in nude athymic mice by streptozotocin injections. At 9 weeks after hyperglycemia, 105 PB-MNCs from diabetic patients, pretreated by EFNB2, were intravenously injected in diabetic mice with hindlimb ischemia. Two weeks later, the postischemic neovascularization was evaluated. The mechanisms involved were investigated by flow cytometry analysis and in vitro cell biological assays. Paw skin blood flow, angiographic score, and capillary density were significantly increased in ischemic leg of diabetic mice receiving EFNB2-activated diabetic PB-MNCs versus those receiving nontreated diabetic PB-MNCs. EFNB2 bound to PB-MNCs and increased the adhesion and transmigration of PB-MNCs. Finally, EFNB2-activated PB-MNCs raised the number of circulating vascular progenitor cells in diabetic nude mice and increased the ability of endogenous bone marrow MNCs to differentiate into cells with endothelial phenotype and enhanced their proangiogenic potential. Therefore, EFNB2 treatment of PB-MNCs abrogates the diabetes-induced stem/progenitor cell dysfunction and opens a new avenue for the clinical development of an innovative and accessible strategy in diabetic patients with critical ischemic diseases.

    Oxidative stress is considered to be the main cause of diabetic complications. In the current study, we investigated the effect of selenium-vitamin E combination and melatonin on lipid peroxidation (LPO) and scavenging enzyme activity in the blood of streptozocin (STZ)-induced diabetic pregnant rats. Forty female Wistar rats were randomly divided into five groups. The first and second groups were used as the non-pregnant control and pregnant control groups, respectively. The third group was the pregnant diabetic group. Vitamin E plus selenium and melatonin were administered to the diabetic pregnant rats consisting fourth and fifth groups, respectively. Diabetes was induced on day 0 of the study by STZ. Blood samples were taken from all animals on the 20th day of pregnancy. LPO level was higher in diabetic pregnant rats than in control, although superoxide dismutase, catalase, and glutathione peroxidase activities were lower in diabetic pregnant animals than in control. LPO levels were lower both in the two treatment groups than in the diabetic pregnant rats, whereas selenium-vitamin E combination and melatonin caused a significant increase in the activities of these antioxidant enzymes (pmelatonin in diabetic pregnant rats. Melatonin did not significantly affect the elevated glucose concentration of diabetic pregnant treated with melatonin group. Vitamin E plus selenium may play a role in preventing diabetes-related diseases of pregnant subjects.

    Full Text Available Gelidium amansii (GA is an edible red algae that is distributed mainly in northeastern Taiwan. This study was designed to investigate the effects of GA on plasma glucose, lipids, and adipocytokines in rats with streptozotocin-nicotinamide-induced diabetes. Rats were divided into four groups: (1 rats without diabetes fed a high-fat diet (control group; (2 rats with diabetes fed a high-fat diet; (3 rats with diabetes fed a high-fat diet with thiazolidinedione in the diet; and (4 rats with diabetes fed a high-fat diet and GA. The experimental diet and drinking water were available ad libitum for 11 weeks. After the 11-week feeding study, plasma glucose, triglyceride, and cholesterol concentrations were lower in rats with diabetes fed the GA diet than in animals with diabetes fed the control diet. In addition, cholesterol and triglyceride excretion were significantly higher in rats with diabetes fed the GA diet. Moreover, GA feeding induced lipolysis in both paraepididymal and perirenal adipose tissues. Adipose tissue (paraepididymal and perirenal weight and triglyceride contents were lower after GA treatment. Plasma adipocytokines including tumor necrosis factor-alpha, interleukin-6, and plasminogen activator inhibitor-1 were reduced by GA feeding in rats with diabetes. The results of the current study suggest that GA feeding may regulate plasma glucose and lipid levels and prevent adipose tissue accumulation in rats with diabetes.

    Diabetes-associated cognitive dysfunction, referred as "diabetic encephalopathy", has been confirmed in a great deal of literature. Current evidence support that oxidative stress, inflammation, energy metabolism imbalance, and aberrant insulin signaling are associated with cognition deficits induced by diabetes. The present study explore the effect of asiaticoside on the cognition behaviors, synapses, and oxidative stress in diabetic rats. Asiaticoside could markedly ameliorate the performance in the Morris Water Maze (decreased latency time and path length, and increased time spent in the target quadrant), which was correlated with its capabilities of suppressing oxidative stress, restoring Na(+)-K(+)-ATPase activity and protecting hippocampal synapses. In vitro, asiaticoside could up-regulate synaptic proteins expression via modulating Phosphoinositide 3-kinase (PI3K)/Protein Kinase B(AKT)/Nuclear Factor -kappa B (NF-κB)-mediated inflammatory pathway in SH-SY5Y cells incubated with high glucose chronically. In conclusion, asiaticoside had beneficial effects on the prevention and treatment of diabetes-associated cognitive deficits, which was involved in oxidative stress, PI3K/Akt/NF-κB pathway and synaptic function in the development of cognitive decline induced by diabetes.

    Fenofibrate (FF), as a peroxisome-proliferator-activated receptor α (PPARα) agonist, has been used clinically for decades to lower lipid levels. In the present study, we examined whether FF can be repurposed to prevent the pathogenesi of the heart in Type 1 diabetes and to describe the underlying mechanism of its action. Streptozotocin (STZ)-induced diabetic mice and their age-matched control mice were treated with vehicle or FF by gavage every other day for 3 or 6 months. FF prevented diabetes-induced cardiac dysfunction (e.g. decreased ejection fraction and hypertrophy), inflammation and remodelling. FF also increased cardiac expression of fibroblast growth factor 21 (FGF21) and sirtuin 1 (Sirt1) in non-diabetic and diabetic conditions. Deletion of FGF21 gene (FGF21-KO) worsened diabetes-induced pathogenic effects in the heart. FF treatment prevented heart deterioration in the wild-type diabetic mice, but could not do so in the FGF21-KO diabetic mice although the systemic lipid profile was lowered in both wild-type and FGF21-KO diabetic mice. Mechanistically, FF treatment prevented diabetes-impaired autophagy, reflected by increased microtubule-associated protein 1A/1B-light chain 3, in the wild-type diabetic mice but not in the FGF21-KO diabetic mice. Studies with H9C2 cells in vitro demonstrated that exposure to high glucose (HG) significantly increased inflammatory response, oxidative stress and pro-fibrotic response and also significantly inhibited autophagy. These effects of HG were prevented by FF treatment. Inhibition of either autophagy by 3-methyladenine (3MA) or Sirt1 by sirtinol (SI) abolished FF's prevention of HG-induced effects. These results suggested that FF could prevent Type 1 diabetes-induced pathological and functional abnormalities of the heart by increasing FGF21 that may up-regulate Sirt1-mediated autophagy.

    Full Text Available Hyperglycemia-induced oxidative stress has been concerned in the development of diabetic nephropathy (DN, which may cause kidney damage associated with inflammation and fibrosis. This study has been conducted to investigate the role of genistein supplementation in an acute DN state. Mice with FBG levels more than 250 mg/dL after alloxan injection (single i.p., 150 mg/kg were considered as diabetic. Diabetic mice (DM were further subdivided according to their FBG levels, medium-high FBG (DMMH < 450 mg/dL and high FBG (DMH; 450 mg/dL and were administrated by an AIG-93G diet supplemented with different doses of genistein (0, 0.025 or 0.1%. After 2 weeks’ treatment, the levels of kidney malondialdehyde (MDA, blood urea nitrogen (BUN, and plasma creatinine and lipid profiles, as well as oxidative stress and inflammation-related markers, were measured (P<0.05. Genistein supplementation improved levels of FBG in the DMMH groups, but not in the DMH group, regardless of the treatment dose. Moreover, the supplementation attenuated kidney oxidative stress indicated by MDA, BUN, and plasma creatinine. In addition, genistein treatment decreased inflammatory markers such as nuclear factor kappa B (p65, phosphorylated inhibitory kappa B alpha, C-reactive protein, monocyte chemotactic protein-1, cyclooxygenase-2, and tumor necrosis factor-alpha and improved oxidative stress markers (nuclear-related factor E2, heme oxygenase-1, glutathione peroxidase, and superoxide dismutase isoforms in treatment groups, regardless of the genistein treatment dose. Furthermore, genistein supplementation inhibited the fibrosis-related markers (protein kinase C, protein kinase C-beta II, and transforming growth factor-beta I in the DN state. However, 0.1% genistein supplementation in diabetes with high FBG levels selectively showed a preventive effect on kidney damage. These results suggest that genistein might be a good protective substance for DN through regulation of

    Full Text Available This study was conducted to determine the expression of matrix metalloproteinase-9 (MMP-9 and tissue inhibitor of metalloproteinase-1 (TIMP-1 in a time-dependent manner and the effect of extracellular-signal-regulated kinases-1/2 (ERK1/2 inhibition on the expressions of MMP-9, TIMP-1, and inflammatory biomarkers in the retinas of diabetic rats. The expression of MMP-9 was quantified by zymography, and the mRNA level of MMP-9 and TIMP-1 was quantified by RT-PCR. The expression of inducible nitric oxide synthase (iNOS, interleukin-6 (IL-6, and tumor necrosis factor-alpha (TNF-α was examined by Western blot analysis. MMP-9 expression was significantly higher in diabetic rat retinas compared to controls at all time points.TIMP-1 expression was nonsignificantly upregulated at 1week of diabetes and was significantly downregulated at 4 and 12 weeks of diabetes. Intravitreal administration of the ERK1/2 inhibitor U0126 prior to induction of diabetes decreased ERK1/2 activation, attenuated diabetes-induced upregulation of MMP-9, iNOS, IL-6, and TNF-α and upregulated TIMP-1 expression. In MMP-9 knockout mice, diabetes had no effect on retinal iNOS expression and its level remained unchanged. These data provide evidence that ERK1/2 signaling pathway is involved in MMP-9, iNOS, IL-6, and TNF-α induction in diabetic retinas and suggest that ERK1/2 can be a novel therapeutic target in diabetic retinopathy.

    Erectile dysfunction (ED) is defined as the inability of the male to attain and/or maintain erection of penis sufficient to permit satisfactory sexual intercourse. Prevalence of impotence in diabetic men is more than 50%. The mechanism of diabetes-induced erectile dysfunction (DIED) is multifactorial, involving many factors. Previous studies focused on the influence of neuropathy and vascular lesions, but endothelial and myogenic disorders played more and more important roles in recent years. Although the treatment methods of DIED are many, drugs and the penis prosthesis implants have become the standard ways at present. Gene delivery vectors have shown a promising perspective, however, there are still some problems which need be solved further in clinical application.%勃起功能障碍(ED)是指不能获得或维持充分勃起以完成令人满意的性交过程.糖尿病患者中50%以上伴有ED,糖尿病性勃起功能障碍(DIED)发病机制复杂,涉及多因素.以往的研究多集中在神经病变和血管病变的影响,近来内皮细胞性及肌源性因素对ED的影响越来越受到重视.目前治疗DIED方法有多种,药物和阴茎假体植入手术在当前还是治疗DIED的标准方式,通过载体转染的基因治疗提供了另一条新的途径,但在临床应用前还需解决一些问题.

    Impaired wound healing is a well-documented phenomenon in diabetes mellitus, yet little is known of the fundamental cause of this pathology. This study examined the effects of streptozotocin (STZ)-induced diabetes on the healing process using three wound models: (i) a linear skin incision (tensile strength), (ii) subcutaneously implanted polyvinyl alcohol sponge PVAs (collagen deposition), and (iii) stainless steel mesh chamber (TGF-beta, IGF-I and its binding proteins, extracellular matrix remodeling enzymes). RIA specific for IGF-I revealed that diabetes induced a 42% (wound fluid) and a 48% (serum) reduction in IGF-I levels. IGF-II western ligand blots found that diabetes produced a marked reduction in the level of a wound fluid 46 kDa IGF binding proteins. A proliferation-based bioassay indicates that TGF-beta level is also reduced in diabetic wound fluid (55%). Diabetes of graded metabolic severity induced by variable doses of STZ (25 mg-200 mg/kg) showed stepwise reduction in wound tensile strength and PVAs collagen deposition. In contrast, zymographic analysis of extracellular matrix proteases revealed that the diabetic wound fluid contains increased levels of 21, 69, and 72 kDa gelatinases. A single dose of TGF-beta (2 micrograms) in a collagen vehicle partially reversed the diabetes-related decrease in the tensile strength of standardized incisions. These data support the premise that wound-healing impairment in diabetes is due, at least in part, to a deficiency in growth factor activity within the wound environment.

    This study investigated the effects of resveratrol (RSV) on retinal functions, glutamate transporters (GLAST) and glutamine synthetase (GS) expression in diabetic rats retina, and on glutamate uptake, GS activity, GLAST and GS expression in high glucose-cultured Müller cells. The electroretinogram was used to evaluate retinal functions. Müller cells cultures were prepared from 5- to 7-day-old Sprague-Dawley rats. The expression of GLAST and GS was examined by qRT-PCR, ELISA and western-blotting. Glutamate uptake was measured as (3)H-glutamate contents of the lysates. GS activity was assessed by a spectrophotometric assay. 1- to 7-month RSV administrations (5 and 10 mg/kg/day) significantly alleviated hyperglycemia and weight loss in diabetic rats. RSV administrations also significantly attenuated diabetes-induced decreases in amplitude of a-wave in rod response, decreases in amplitude of a-, and b-wave in cone and rod response and decreases in amplitude of OP2 in oscillatory potentials. 1- to 7-month RSV treatments also significantly inhibited diabetes-induced delay in OP2 implicit times in scotopic 3.0 OPS test. The down-regulated mRNA and protein expression of GLAST and GS in diabetic rats retina was prevented by RSV administrations. In high glucose-treated cultures, Müller cells' glutamate uptake, GS activity, GLAST and GS expression were decreased significantly compared with normal control cultures. RSV (10, 20, and 30 mmol/l) significantly inhibited the HG-induced decreases in glutamate uptake, GS activity, GLAST and GS expression (at least P < 0.05). These beneficial results suggest that RSV may be considered as a therapeutic option to prevent from diabetic retinopathy.

    We have shown previously that heat stroke produced by whole body hyperthermia (WBH) for 4 h at 38°C in diabetic rats exacerbates blood-brain barrier breakdown, brain edema formation and neuronal cell injury as compared to healthy animals after identical heat exposure. In this combination of diabetes and WBH, normal therapeutic measures do not induce sufficient neuroprotection. Thus, we investigated whether nanowired mesenchymal cells (MSCs) when delivered systemically may have better therapeutic effects on brain damage in diabetic rats after WBH. Diabetes induced by streptozotocin administration (75 mg/kg, i.p, daily for 3 days) in rats resulted in clinical symptoms of the disease within 4 to 6 weeks (blood glucose level 20 to 30 mmoles/l as compared to saline control groups (4 to 6 mmoles/l). When subjected to WBH, these diabetic rats showed a 4-to 6-fold exacerbation of blood-brain barrier breakdown to Evans blue and radioiodine, along with brain edema formation and neuronal cell injury. Intravenous administration of rat MSCs (1x10(6)) to diabetic rats one week before WBH slightly reduced brain pathology, whereas TiO2 nanowired MSCs administered in an identical manner resulted in almost complete neuroprotection. On the other hand, MSCs alone significantly reduced brain pathology in saline-treated rats after WBH. These observations indicate that nanowired delivery of stem cells has superior therapeutic potential in heat stroke with diabetes, pointing to novel clinical perspectives in the future.

    Among the diabetic complications, diabetic foot ulcer due to delayed wound healing is one of the most significant clinical problems. Early inflammatory stage is important for better prognosis during wound healing. Thus, regulation of inflammatory response during early stage of wound healing is main target for complete cutaneous recovery. This study investigated the role of genistein supplementation in inflammation and oxidative stress, which are related to NLRP3 inflammasome, NFκB and Nrf2 activation, during cutaneous wound healing in alloxan-induced diabetic mice. Mice with diabetes with fasting blood glucose (FBG) levels > 250 mg/dl were fed diets with AIN-93G rodent diet containing 0%, 0.025% (LG) or 0.1% (HG) genistein. After 2 weeks of genistein supplementation, excisional wounds were made by biopsy punches (4 mm). Genistein supplementation improved fasting glucose levels and wound closure rate. Moreover, genistein supplementation restored NLRP3 inflammasome (NLRP3, ASC and caspase-1) at the basal level and ameliorated both inflammation (TNFα, iNOS, COX2 and NFκB) and antioxidant defense system (Nrf2, HO-1, GPx, and catalase) during early stage of wound healing in diabetic mice. Taken together, genistein supplementation would be a potential therapeutic nutrient in prevention and treatment of delayed wound healing by modulation of inflammation and oxidative stress during inflammatory stage.

    Learning and memory impairment occurs in diabetes. Salvia officinalis L. (SO) has been used in Iranian traditional medicine as a remedy against diabetes. We hypothesized that chronic administration of SO (400, 600 and 800mg/kg, p.o.) and its principal constituent, rosmarinic acid, would affect on passive avoidance learning (PAL) and memory in streptozocin-induced diabetic and non-diabetic rats. We also explored hypoglycemic and antioxidant activities of SO as the possible mechanisms. Treatments were begun at the onset of hyperglycemia. PAL was assessed 30days later. Retention test was done 24h after training. At the end, animals were weighed and blood samples were drawn for further analyzing of glucose and oxidant/antioxidant markers. Diabetes induced deficits in acquisition and retrieval processes. SO (600 and 800mg/kg) and rosmarinic acid reversed learning and memory deficits induced by diabetes and improved cognition of healthy rats. While the dose of 400mg/kg had no effect, the higher doses and rosmarinic acid inhibited hyperglycemia and lipid peroxidation as well as enhanced the activity of antioxidant enzymes superoxide dismutase and catalase. SO prevented diabetes-induced acquisition and memory deficits through inhibiting hyperglycemia, lipid peroxidation as well as enhancing antioxidant defense systems. Therefore, SO and its principal constituent rosmarinic acid represent a potential therapeutic option against diabetic memory impairment which deserves consideration and further examination.

    Objective Our purpose in this study is to investigate genes involved in the development of diabetes-induced embryonic malformations. Methods Two groups of 70-90 day old Sprague-Dawley rats were employed in our study: group 1 was normal control rats receiving a normal diet (n=3); group 2 consisted of experimentally-induced diabetic rats by intravenous injection of 65mg/kg of streptozotocin(STZ) on pregnancy day 6 with an attempt to reproduce malformations in embryos (n=3). Embryos were examined on day 12 under light microscopy to look for morphological defect of the neural tube (NTD). Yolk sac cells were harvested from each group and RNA was isolated. Genes expression profiles in yolk sac cells were analyzed using a DNA microarray technique. Results Gene expression patterns were compared in a total of 1200 genes between experimentally-induced diabetic rats and normal control rats, and 79 of genes were found to express differently between the two groups. Forty-two of genes were up-regulated in yolk sac cells of diabetic rats, such as apoptosis related genes BAX, bcl-2, heat shock 70kD protein and glucose-transporter 3; 37 of genes were down-regulated, such as phospholipase A2, insulin-like growth factor II receptor. Conclusion Understanding of differently expressed genes should help us disclose the potential molecular mechanisms underlying the developmental process during diabetes-associated embryonic morphogenesis, and it also might provide a useful tool in rapid diagnosis and prevention of malformation in early gestation stage of diabetic subjects.%目的探讨妊娠合并糖尿病诱发胚胎先天性神经管缺陷的差异表达基因,揭示胚胎先天性神经管缺陷发生、发展的分子机制.方法选用2组的70~90天的SD 大鼠:第1组(n=3)为接受常规饲养的正常对照组;第2组(n=3)为实验组:尾静脉注射65mg/kg链脲菌素(STZ) ,构建妊娠合并糖尿病诱发胚胎先天性神经管缺陷组大鼠动物模型.于妊娠第12天取

    The argan tree plays an important socioeconomic and ecologic role in South Morocco. Moreover, there is much evidence for the beneficial effects of virgin argan oil (VAO) on human health. Thus, this study investigated whether administering VAO to rats can prevent the development of diabetes. VAO extracted by a traditional method from the almonds of Argania spinosa (2 mL/kg) was administered orally (for 7 consecutive days) to rats before and during intraperitoneal alloxan administration (75 mg/kg for 5 consecutive days). An alloxan diabetic-induced untreated group and treated by table oil were used as control groups. Body mass, blood glucose and hepatic glycogen were evaluated. In the present study, subchronic treatment with VAO at a dose of 2 mL/kg, before the experimental induction of diabetes, prevented the body mass loss, induced a significant reduction of blood glucose and a significant increase of hepatic glycogen level (p argan oil should be further investigated in a human study to clarify its possible role in reducing weight loss in diabetics, and even in inhibiting the development or progression of diabetes. This antidiabetic effect could be due to the richness of VAO in tocopherols, phenolic compounds and unsaturated fatty acids.

    2016-03-01

    The dementia prevention consists of three steps, primary prevention of dementia is to prevent from normal and mild cognitive impairment to dementia, secondary prevention is early detection and early treatment of dementia, and tertiary prevention is three stages of progress prevention of dementia. Primary prevention of dementia had been considered impossible until recently, but potential scientific evidence has been shown recently. The fact that 4.62 million people are person with dementia and 400 million people are person with mild cognitive impairment are considered to be urgent problem and we must intend to perform dementia prevention from primary to tertiary prevention thoroughly. We perform dementia screening using touch panel type computer and we recommend person with mild cognitive impairment to join dementia prevention classroom. Therefore, we can prevent progression from mild cognitive impairment to dementia (primary prevention). Early diagnosis and introduction to the specialized medical institution are needed if you find early stage of dementia and treat early (secondary prevention). To prevent progression by the appropriate drug treatment and care for dementia is required (tertiary prevention).

  16. Prevention of Streptozotocin-Induced Diabetic Nephropathy by MG132: Possible Roles of Nrf2 and IκB

    Wang, Yangwei; Tan, Yi; Miao, Lining

    2017-01-01

    Our previous study showed that proteasomal inhibitor MG132 can prevent diabetic nephropathy (DN) along with upregulation of nuclear factor (erythroid-derived 2)-like 2 (Nrf2). The present study was to investigate whether MG132 can prevent DN in wild-type and Nrf2-KO mice. Type 1 diabetes was induced in wild-type and Nrf2-KO mice by multiple low doses of streptozotocin. Two weeks after streptozotocin injection, both wild-type and Nrf2-KO mice were randomly divided into four groups: control, MG132, DM, and DM/MG132. MG132 (10 μg/kg/day) or vehicle was administered intraperitoneally for 4 months. Renal function, morphology, and biochemical changes were measured after 4-month treatment with MG132. MG132 treatment suppressed proteasomal activity in the two genotypes. In wild-type mice, MG132 attenuated diabetes-induced renal dysfunction, fibrosis, inflammation, and oxidative damage along with increased Nrf2 and IκB expression. Deletion of Nrf2 gene resulted in a partial, but significant attenuation of MG132 renal protection in Nrf2-KO mice compared with wild-type mice. MG132-increased IκB expression was not different between wild-type and Nrf2-KO mice. This work indicates that MG132 inhibits diabetes-increased proteasomal activity, resulting in Nrf2 and IκB upregulation and renal protection, which could be used as a strategy to prevent diabetic nephropathy.

    2014-01-01

    Full Text Available This study aimed to evaluate the efficacy of sitagliptin, a dipeptidyl peptidase IV (DPP-IV inhibitor, in preventing the deleterious effects of diabetes on the kidney in an animal model of type 2 diabetes mellitus; the Zucker diabetic fatty (ZDF rat: 20-week-old rats were treated with sitagliptin (10 mg/kg bw/day during 6 weeks. Glycaemia and blood HbA1c levels were monitored, as well as kidney function and lesions. Kidney mRNA and/or protein content/distribution of DPP-IV, GLP-1, GLP-1R, TNF-α, IL-1β, BAX, Bcl-2, and Bid were evaluated by RT-PCR and/or western blotting/immunohistochemistry. Sitagliptin treatment improved glycaemic control, as reflected by the significantly reduced levels of glycaemia and HbA1c (by about 22.5% and 1.2%, resp. and ameliorated tubulointerstitial and glomerular lesions. Sitagliptin prevented the diabetes-induced increase in DPP-IV levels and the decrease in GLP-1 levels in kidney. Sitagliptin increased colocalization of GLP-1 and GLP-1R in the diabetic kidney. Sitagliptin also decreased IL-1β and TNF-α levels, as well as, prevented the increase of BAX/Bcl-2 ratio, Bid protein levels, and TUNEL-positive cells which indicates protective effects against inflammation and proapoptotic state in the kidney of diabetic rats, respectively. In conclusion, sitagliptin might have a major role in preventing diabetic nephropathy evolution due to anti-inflammatory and antiapoptotic properties.

  12. Prevention Of Stroke

    Directory of Open Access Journals (Sweden)

    Nagaraja D

    2005-01-01

    Full Text Available Stroke is an important cause for neurological morbidity and mortality. Prevention of ischemic stroke involves identification and prevention of risk factors and optimal use of pharmacotherapy. Risk factors have been classified as modifiable and non-modifiable; control of modifiable factors should prevent stroke occurrence. Stroke prevention has been described at three levels: primary, secondary and tertiary. Prolonged hypertension increases an individual′s risk for developing fatal or nonfatal stroke by three times and its control has been shown to prevent stroke. Diabetes mellitus is an important cause for microangiopathy and predisposes to stroke. Statin trials have shown significant reduction in stroke in those who were treated with statins. Stroke risk can be reduced by avoiding tobacco use, control of obesity and avoiding sedentary life style. Anti platelet medications are effective for secondary prevention of stroke. Educating society regarding modifiable risk factors and optimal use of pharmacotherapy form the cornerstone for the prevention of stroke.

    Angiotensin-(1-7) [Ang-(1-7)] may have beneficial effects in diabetes mellitus-induced erectile dysfunction (DMIED) but its molecular actions in the diabetic corpus cavernosum (CC) are not known. We characterized the effects of diabetes and/or chronic in vivo administration of Ang-(1-7) on vascular reactivity in the rat corpus cavernosum (CC) and on protein expression levels of potential downstream effectors of the renin-angiotensin-aldosterone system (RAAS) such as angiotensin-converting enzyme (ACE), ACE2, Rho kinases 1 and 2 (ROCK1 and ROCK2), and omega-hydroxylase, the cytochrome-P450 enzyme that metabolizes arachidonic acid to form the vasoconstrictor, 20-hydroxyeicosatetraenoic acid. Streptozotocin-treated rats were chronicically administered Ang-(1-7) with or without A779, a Mas receptor antagonist, during weeks 4 to 6 of diabetes. Ang-(1-7) reversed diabetes-induced abnormal reactivity to vasoactive agents (endothelin-1, phenylepherine, and carbachol) in the CC without correcting hyperglycemia. Six weeks of diabetes led to elevated ACE, ROCK1, ROCK 2, and omega-hydroxylase and a concomitant decrease in ACE2 protein expression levels that were normalized by Ang-(1-7) treatment but not upon coadministration of A779. These data are supportive of the notion that the beneficial effects of Ang-(1-7) in DMIED involve counterregulation of diabetes-induced changes in ACE, ACE2, Rho kinases, and omega-hydroxylase proteins in the diabetic CC via a Mas receptor-dependent mechanism.

  15. Alendronate Can Improve Bone Alterations in Experimental Diabetes by Preventing Antiosteogenic, Antichondrogenic, and Proadipocytic Effects of AGEs on Bone Marrow Progenitor Cells

    Science.gov (United States)

    2016-01-01

    Bisphosphonates such as alendronate are antiosteoporotic drugs that inhibit the activity of bone-resorbing osteoclasts and secondarily promote osteoblastic function. Diabetes increases bone-matrix-associated advanced glycation end products (AGEs) that impair bone marrow progenitor cell (BMPC) osteogenic potential and decrease bone quality. Here we investigated the in vitro effect of alendronate and/or AGEs on the osteoblastogenic, adipogenic, and chondrogenic potential of BMPC isolated from nondiabetic untreated rats. We also evaluated the in vivo effect of alendronate (administered orally to rats with insulin-deficient Diabetes) on long-bone microarchitecture and BMPC multilineage potential. In vitro, the osteogenesis (Runx2, alkaline phosphatase, type 1 collagen, and mineralization) and chondrogenesis (glycosaminoglycan production) of BMPC were both decreased by AGEs, while coincubation with alendronate prevented these effects. The adipogenesis of BMPC (PPARγ, intracellular triglycerides, and lipase) was increased by AGEs, and this was prevented by coincubation with alendronate. In vivo, experimental Diabetes (a) decreased femoral trabecular bone area, osteocyte density, and osteoclastic TRAP activity; (b) increased bone marrow adiposity; and (c) deregulated BMPC phenotypic potential (increasing adipogenesis and decreasing osteogenesis and chondrogenesis). Orally administered alendronate prevented all these Diabetes-induced effects on bone. Thus, alendronate could improve bone alterations in diabetic rats by preventing the antiosteogenic, antichondrogenic, and proadipocytic effects of AGEs on BMPC. PMID:27840829

  11. Prevention of preterm birth.

    LENUS (Irish Health Repository)

    Flood, Karen

    2012-02-01

    Preterm birth (delivery before 37 completed weeks of gestation) is common and rates are increasing. In the past, medical efforts focused on ameliorating the consequences of prematurity rather than preventing its occurrence. This approach resulted in improved neonatal outcomes, but it remains costly in terms of both the suffering of infants and their families and the economic burden on society. Increased understanding of the pathophysiology of preterm labor has altered the approach to this problem, with increased focus on preventive strategies. Primary prevention is a limited strategy which involves public education, smoking cessation, improved nutritional status and avoidance of late preterm births. Secondary prevention focuses on recurrent preterm birth which is the most recognisable risk factor. Widely accepted strategies include cervical cerclage, progesterone and dedicated clinics. However, more research is needed to explore the role of antibiotics and anti-inflammatory treatments in the prevention of this complex problem.

    Meunier, P J

    1993-11-30

    For a 50-year old Caucasian woman today, the risk of a hip fracture over her remaining life-time is about 17%. Tomorrow the situation will clearly be worse because the continuous increase in life expectancy will cause a three-fold increase in worldwide fracture incidence over the next 60 years. Through diagnostic bone mass measurements at the hip and assessment of biochemical parameters, a great deal has been learned in recent years about reduction of hip fracture risk. Preventive strategies are based on prevention of falls, use of hip protectors, and prevention of bone fragility. The latter includes the optimization of peak bone mass during childhood, postmenopausal estrogen replacement therapy, and also late prevention consisting in reversing senile secondary hyperparathyroidism, which plays an important role in the decrease of skeletal strength. This secondary hyperparathyroidism, which results from both vitamin D insufficiency and low calcium intake, is preventable with vitamin D3 and calcium supplements. They have recently been shown capable of providing effective prevention of hip fractures in elderly women living in nursing homes, with a reduction of about 25% in the number of hip fractures noted in a 3-year controlled study in 3,270 women (intention-to-treat analysis). In conclusion, it is never too early to reduce the risk of osteoporosis and never too late to prevent hip fractures.

    Full Text Available Life style factors are contributing significantly in cancer prevention. With the intake of proper and balanced diet ,cancer prevention is possible. Many foods are associated either with incidence or prevention of cancer. Plant based foods like fresh fruits, vegetables and whole grains rich in fiber, b-carotene, vitamins and antioxidants can prevent cancer. Fiber rich foods increase bowel movement, decreasing the absorption of cholesterol. Pumpkin, carrots contain b-carotenes. Leafy vegetables, broccoli, cabbage, cauliflower, peas and beans are rich in fiber and stimulate cancer preventing enzyme induction. Vitamin C rich citrus fruits can stimulate immune system. Garlic and onions can stimulate enzymes that can suppress tumor growth. Turmeric used in cooking can prevent colorectal cancer. Topical application of turmeric can prevent breast cancer in women. On the other hand, certain foods can cause cancer. Refined foods, high fat foods, deep fried foods, processed foods and low fiber foods increase cancer risk. Red meat, processed meat and barbeques contain a carcinogen called acrylamide. Foods prepared with hydrogenated fats contain transfats which increase risk for breast, ovarian, cervical and lung cancer. Consumption of alcohol increasing the risk for cancers of digestive system.

  19. Prevention of cisplatin nephrotoxicity

    Directory of Open Access Journals (Sweden)

    Hayati Fatemeh

    2016-01-01

    Full Text Available Cisplatin has a well-established role in the treatment of broad spectrum of malignancies; however its use is limited because of cisplatin-induced nephrotoxicity (CIN which can be progressive in more than 50% of cases. The most important risk factors for CIN include higher doses of cisplatin, previous cisplatin chemotherapy, underlying kidney damage and concurrent treatment with other potential nephrotoxin agents, such as aminoglycosides, nonsteroidal anti-inflammatory agents, or iodinated contrast media. Different strategies have been offered to diminish or prevent nephrotoxicity of cisplatin. The standard approach for prevention of CIN is the administration of lower doses of cisplatin in combination with full intravenous hydration prior and after cisplatin administration. Cisplatin-induced oxidative stress in the kidney may be prevented by natural antioxidant compounds. The results of this review show that many strategies for prevention of CIN exist, however, attention to the administration of these agent for CIN is necessary.

    2016-01-01

    The number of patients undergoing hematopoietic cell and solid organ transplantation are increasing every year, as are the number of centers both transplanting and caring for these patients. Improvements in transplant procedures, immunosuppressive regimens, and prevention of transplant-associated complications have led to marked improvements in survival in both populations. Infections remain one of the most important sources of excess morbidity and mortality in transplant, and therefore, infection prevention strategies are a critical element for avoiding these complications in centers caring for high-risk patients. This manuscript aims to provide an update of recent data on prevention of major healthcare-associated infections unique to transplantation, reviews the emergence of antimicrobial resistant infections, and discusses updated strategies to both identify and prevent transmission of these pathogens in transplant recipients.

    Grigor' yev, N.I.; Khayrullin, B.Yu.; Nomin, V.I.; Ukdov, I.A.

    1983-01-01

    A blowout preventer is proposed which contains a body, blocks with rods, tops, hydraulic cylinders, spindles linked with the rods of the hydraulic cylinders and with the blocks which are installed in spindle stops and locking devices. To ensure the capability of backing up the hydraulic drive with a manual drive when using the preventer with traverse linked hydraulic cylinders installed on the body parallel to the axis of movement of the blocks, the spindles are linked with the rods of the blocks by a telescopic helical connection, are connected with the traverses with the capability of turning and are made with beads for interacting with the traverses when the preventer is closed. The stops are equal in length to the travel of the block for locking the spindles during opening of the preventer.

    2015-01-01

    Hepatitis B virus (HBV) causes life-threatening liver disease. It is transmitted through a horizontal route or a mother-to-infant route, and the latter is the major route in endemic areas. Prevention of HBV infection by immunization is the best way to eliminate HBV-related diseases. The HBV vaccine is the first human vaccine using a viral antigen from infected persons, which is safe and effective. Either passive immunization by hepatitis B immunoglobulin (HBIG) or active immunization by HBV vaccine is effective, and a combination of both yields the best efficacy in preventing HBV infection. The impact of universal HBV immunization is huge, with 90%–95% effectiveness in preventing chronic HBV infection. It is the first cancer preventive vaccine with a protective efficacy against hepatocellular carcinoma (HCC) of ∼70%. Nevertheless, further effort is still needed to avoid vaccine failure and to increase the global coverage rate. PMID:25732034

    1995-09-01

    Prosperity without pollution, and the consideration of how to achieve this economic and environmental imperative, has become the fundamental environmental theme of the 1990s. The new strategy--pollution prevention--will serve s the keystone of federal, state, and local environmental policy. The challenge is to switch from two decades of environmental policy based on pollution controls and government-mandated regulations to a future environmental policy based on pollution prevention, source reduction, recycling, and waste minimization. To make this change will require a new social compact among environmental, industrial, and regulatory interests. This chapter focuses on the role of chemistry and the contributions of synthetic and process analytical chemists. It also describes the implementation of pollution prevention concepts into the premanufacturing notice review process mandated by Section 5 of the Toxic Substances Control Act (TSCA) and discusses the implications of pollution prevention for chemical safety. 55 refs.

  14. Prevention of running injuries.

    Science.gov (United States)

    Fields, Karl B; Sykes, Jeannie C; Walker, Katherine M; Jackson, Jonathan C

    2010-01-01

    Evidence for preventive strategies to lessen running injuries is needed as these occur in 40%-50% of runners on an annual basis. Many factors influence running injuries, but strong evidence for prevention only exists for training modification primarily by reducing weekly mileage. Two anatomical factors - cavus feet and leg length inequality - demonstrate a link to injury. Weak evidence suggests that orthotics may lessen risk of stress fracture, but no clear evidence proves they will reduce the risk of those athletes with leg length inequality or cavus feet. This article reviews other potential injury variables, including strength, biomechanics, stretching, warm-up, nutrition, psychological factors, and shoes. Additional research is needed to determine whether interventions to address any of these will help prevent running injury.

    Jensen, J Daniel; Wing, Gregory J; Dellavalle, Robert P

    2010-01-01

    Melanoma has continued to rise in incidence despite public efforts to promote sun protection behaviors. Because sunscreen use does not completely prevent skin cancer induced by ultraviolet radiation, additional chemopreventive methods for protecting against and reversing the effects of ultraviolet photodamage need evaluation. Recent years have brought increased interest in dietary factors, such as natural botanicals and vitamins, for the prevention of melanoma. This contribution provides a narrative review of the relevant, nutrition-related literature found by searching the keywords "melanoma chemoprevention," "nutrition and melanoma," "dietary botanicals and melanoma prevention," "green tea and melanoma," "vitamin D and melanoma," and "vitamin E and melanoma" in the PubMed database. Although randomized controlled trials of humans are lacking, basic science and epidemiologic studies show promising benefits of many natural products in chemoprevention for melanoma. Future studies, hopefully, will yield concrete answers and clarify the role of commonly available dietary nutrients in melanoma chemoprevention.

  18. Probiotics for allergy prevention.

    Science.gov (United States)

    West, C E

    2016-01-01

    Probiotics, given either as a supplement or in infant foods, have been evaluated in randomised controlled trials for allergy prevention. Here, the aim is to give an overview of the results from these primary prevention studies and to discuss current strategies. In most studies, single strains or a mixture of strains of lactic acid bacteria and bifidobacteria have been used--prenatally, postnatally or perinatally. Several meta-analyses have reported a moderate benefit of probiotics for eczema prevention, and the most consistent effect has been observed with a combined perinatal intervention in infants at high risk of allergic disease due to familial predisposition. In a recent meta-analysis, the use of multi-strain probiotics appeared to be most effective for eczema prevention. No preventive effect has been shown for other allergic manifestations. As long-term follow-up data on later onset allergic conditions (asthma and allergic rhinitis) are available only from a few of the initiated studies, reports from ongoing follow-up studies that are adequately powered to examine long-term outcomes are anticipated to provide more insight. Arguably, the differences in many aspects of study design and the use of different probiotic strains and combinations have made direct comparison difficult. To date, expert bodies do not generally recommend probiotics for allergy prevention, although the World Allergy Organization (WAO) in their recently developed guidelines suggests considering using probiotics in pregnant women, during breastfeeding and/or to the infant if at high risk of developing allergic disease (based on heredity). However, in concordance with other expert bodies, the WAO guideline panel stressed the low level of evidence and the need for adequately powered randomised controlled trials and a more standardised approach before clinical recommendations on specific strains, dosages and timing can be given.

    Due to progressive advances in surgical techniques, immunosuppressive therapies, and supportive care, outcomes from both solid organ transplantation and hematopoietic stem cell transplantation continue to improve. Thrombosis remains a challenging management issue in this context, with implications for both graft survival and long-term quality of life. Unfortunately, there remains a general paucity of pediatric-specific data regarding thrombosis incidence, risk stratification, and the safety or efficacy of preventative strategies with which to guide treatment algorithms. This review summarizes the available evidence and rationale underlying the spectrum of current practices aimed at preventing thrombosis in the transplant recipient, with a particular focus on risk factors, pathophysiology, and described antithrombotic regimens.

    The prevention of tooth decay and the treatment of lesions and cavities are ongoing challenges in dentistry. In recent years, biomimetic approaches have been used to develop nanomaterials for inclusion in a variety of oral health-care products. Examples include liquids and pastes that contain nano-apatites for biofilm management at the tooth surface, and products that contain nanomaterials for the remineralization of early submicrometre-sized enamel lesions. However, the treatment of larger visible cavities with nanomaterials is still at the research stage. Here, we review progress in the development of nanomaterials for different applications in preventive dentistry and research, including clinical trials.

    A common approach to malaria prevention is to follow the "A, B, C, D" rule: Awareness of risk, Bite avoidance, Compliance with chemoprophylaxis, and prompt Diagnosis in case of fever. The risk of acquiring malaria depends on the length and intensity of exposure; the risk of developing severe disease is primarily determined by the health status of the traveler. These parameters need to be assessed before recommending chemoprophylaxis and/or stand-by emergency treatment. This review discusses the different strategies and drug options available for the prevention of malaria during and post travel.

    2006-05-01

    Full Text Available Background: The condition of non-specific back pain is characterized by high prevalence, non satisfactory therapeutic options and severe socioeconomic consequences. Therefore prevention seems an attractive option to downsize the problem. However, the construction of effective preventive measures is complicated by the obscure aetiology of the condition, the multidimensionality of risk and prognostic factors (bio psychosocial model! and the variability of its natural as well as clinical course. This led to the development of a wide variety of preventive measures: e. g. exercise programs, educational measures (including back school, ergonomic modification of the work environment, mechanical supports (e. g. back belts as well as multidisciplinary interventions. For two reasons the workplace seems to be a suitable setting for prevention. First, because a number of strong risk factors are associated with working conditions and second, because it allows addressing a large proportion of the adult population. Against this background the assessment at hand sets out to answer the following questions: What is the amount and methodological quality of the available scientific literature on the effectiveness of back pain prevention in the workplace environment? What are effective measures for the prevention of back pain and its consequences in the workplace environment and how effective are they? Is back pain prevention in the workplace environment cost-effective? Is there a need for more research? As primary outcomes for effectiveness the assessment will focus on time lost from work and the frequency and duration of episodes with back pain. The preventive measures assessed belong to the following categories: exercise programs, educational and information measures, multidimensional interventions, back belts, lifting teams and ergonomic interventions. Methods: The assessment is based on a systematic review of the published literature according to the

    Gut flora and probiotics have potential to affect health and disease far beyond the gut. There is increasing evidence that probiotics have beneficial effects in preventing a wide range of conditions and improving health. Randomized, double-blind studies have provided evidence of the effectiveness of probiotics for preventing various diarrheal illnesses as well as allergic disorders. Evidence for their efficacy for use in the prevention and treatment of bacterial vaginosis and urinary tract infections is also mounting. In addition, probiotics may be useful for preventing respiratory infections, dental caries, necrotizing enterocolitis, and certain aspects of inflammatory bowel disease. Data also suggest that probiotics may promote good health in day care and work settings, and may enhance growth in healthy as well as ill and malnourished children. Results from meta-analyses and systematic reviews that combine results of studies from different types of probiotics to examine the effects in any disease state should be interpreted with caution. Specific strains are effective in specific disease states. No 2 probiotics are exactly alike; we should not expect reproducible results from studies that employ different species or strains, variable formulations, and diverse dosing schedules.

    Full Text Available Operation or any invasive procedure is a stressful event involving risks and complications. We should be able to offer a guarantee that the right procedure will be done on right person in the right place on their body. “Never events” are definable. These are the avoidable and preventable events. The people affected from consequences of surgical mistakes ranged from temporary injury in 60%, permanent injury in 33% and death in 7%”.World Health Organization (WHO [1] has earlier said that over seven million people across the globe suffer from preventable surgical injuries every year, a million of them even dying during or immediately after the surgery? The UN body quantified the number of surgeries taking place every year globally 234 million. It said surgeries had become common, with one in every 25 people undergoing it at any given time. 50% never events are preventable. Evidence suggests up to one in ten hospital admissions results in an adverse incident. This incident rate is not acceptable in other industries. In order to move towards a more acceptable level of safety, we need to understand how and why things go wrong and have to build a reliable system of working. With this system even though complete prevention may not be possible but we can reduce the error percentage2. To change present concept towards patient, first we have to change and replace the word patient with medical customer. Then our outlook also changes, we will be more careful towards our customers.

    Suicide is a major public health problem and the number of suicide victims has exceeded 30,000 a year since 1998 in Japan. The rates of depression are extremely high in suicide victims. Social and environmental factors, such as the slow recovery of Japanese economy, could have a strong effect on depression and suicide, especially in middle-aged men. To reduce the number of suicide victims, we need to use both population-based and high-risk approaches, targeting individuals with high psychological and socioeconomic risks of suicide, especially depressed patients. On the other hand, the role of antidepressants in suicide prevention is a major question given the high prevalence of both depression and depression-related suicidality. Because treatment and prevention of suicide are complex and encompass many factors, success will need multi-sector collaboration.

    Directory of Open Access Journals (Sweden)

    M S Ansari

    2003-01-01

    Full Text Available Objectives: Many urological cancers like prostate and bladder have protracted course and maybe ideal for chemoprevention strategies. This article reviews the biol-ogy, epidemiology and possible preventive strategies for the various urological cancers. Methods: The author reviewed the relevant articles published in the last 20 years and studied the biology of the various urological cancers. An attempt is made to identify the various dietary, nutritional and occupation-related factors implicated in the onset and progression of various urological cancers. The various interventions and clinical trial results are described to prove the relevance of these factors. Results: Epidemiological reports provide the strongest evidence of protective role for dietary agents in cancer of prostate, bladder and kidney. Cancers of prostate and blad-der are uniquely suitable for chemopreventive strategies. For prostate cancer strong evidence exists for a preven-tive effect of reduced fat intake, vitamin E, selenium, lycopene and soya proteins. Vitamin A administration shows a strong inverse relation to bladder cancer. Better prevention is seen with combination of high doses of vita-mins A, C, E and B6. High-energy intake is related to the higher incidence of renal cell carcinoma (RCC. While vitamins D and E supplementation has resulted in lower incidence of RCC. Conclusions: Numerous studies implicate dietary and nutritional factors in the onset and progression of various urological cancers. Hence, it is possible that bioactive compounds (anti-oxidants like vits. A, D, C, and E, min-erals like selenium and carotenoids like lycopene along with reduction of animal fat in diet can be a part of pre-ventive strategies for various urological cancers.

    Foot blisters are the most common medical problem faced by Soldiers during foot march operations and, if untreated, they can lead to infection. Foot blisters are caused by boots rubbing on the foot (frictional forces), which separates skin layers and allows fluid to seep in.

Nevertheless, it is still lethal in one out of two affected women though the introduction of cytological screening has dramatically reduced the mortality. Progressive diffusion of anti-HPV vaccination, the broadening of the viral types concerned, its association with existing screening measures and finally the introduction of viral detection as a screening tool must optimize the results already obtained.

  14. Guidelines for prevention in psychology.

    Science.gov (United States)

    2014-04-01

    The effectiveness of prevention to enhance human functioning and reduce psychological distress has been demonstrated. From infancy through adulthood, access to preventive services and interventions is important to improve the quality of life and human functioning and reduce illness and premature death. The importance of prevention is consistent with the Patient Protection and Affordable Care Act of 2010. Even with the increased focus on prevention, psychology training programs rarely require specific courses on prevention. In particular, conceptualizations about best practices in prevention, particularly at the environmental level, are lacking. Therefore, psychologists engaged in prevention can benefit from a set of guidelines that address and inform prevention practices. Accordingly, the Guidelines for Prevention in Psychology are intended to "inform psychologists, the public, and other interested parties regarding desirable professional practices" in prevention. The Prevention Guidelines are recommended based on their potential benefits to the public and the professional practice of psychology. They support prevention as an important area of practice, research, and training for psychologists. The Guidelines give increased attention to prevention within APA, encouraging psychologists to become involved with preventive activities relevant to their area of practice.

  15. Preventing Ophthalmia Neonatorum

    Directory of Open Access Journals (Sweden)

    Dorothy L Moore

    2015-01-01

    Full Text Available The use of silver nitrate as prophylaxis for neonatal ophthalmia was instituted in the late 1800s to prevent the devastating effects of neonatal ocular infection with Neisseria gonorrhoeae. At that time – during the preantibiotic era – many countries made such prophylaxis mandatory by law. Today, neonatal gonococcal ophthalmia is rare in Canada, but ocular prophylaxis for this condition remains mandatory in some provinces/ territories. Silver nitrate drops are no longer available and erythromycin, the only ophthalmic antibiotic eye ointment currently available for use in newborns, is of questionable efficacy. Ocular prophylaxis is not effective in preventing chlamydial conjunctivitis. Applying medication to the eyes of newborns may result in mild eye irritation and has been perceived by some parents as interfering with mother-infant bonding. Physicians caring for newborns should advocate for rescinding mandatory ocular prophylaxis laws. More effective means of preventing ophthalmia neonatorum include screening all pregnant women for gonorrhea and chlamydia infection, and treatment and follow-up of those found to be infected. Mothers who were not screened should be tested at delivery. Infants of mothers with untreated gonococcal infection at delivery should receive ceftriaxone. Infants exposed to chlamydia at delivery should be followed closely for signs of infection.

  20. The prevention of diabetic cardiomyopathy by non-mitogenic acidic fibroblast growth factor is probably mediated by the suppression of oxidative stress and damage.

    Directory of Open Access Journals (Sweden)

    Chi Zhang

    Full Text Available BACKGROUND: Emerging evidence showed the beneficial effect of acidic fibroblast growth factor (aFGF on heart diseases. The present study investigated whether non-mitogenic aFGF (nm-aFGF can prevent diabetic cardiomyopathy and the underlying mechanisms, if any. METHODOLOGY/PRINCIPAL FINDINGS: Type 1 diabetes was induced in mice by multiple intraperitoneal injections of low-dose streptozotocin. Hyperglycemic and age-matched control mice were treated with or without nm-aFGF at 10 µg/kg daily for 1 and 6 months. Blood pressure and cardiac function were assessed. Cardiac H9c2 cell, human microvascular endothelial cells, and rat cardiomyocytes were exposed to high glucose (25 mM for mimicking an in vitro diabetic condition for mechanistic studies. Oxidative stress, DNA damage, cardiac hypertrophy and fibrosis were assessed by real-time qPCR, immunofluorescent staining, Western blotting, and pathological examination. Nm-aFGF significantly prevented diabetes-induced hypertension and cardiac dysfunction at 6 months. Mechanistic studies demonstrated that nm-aFGF showed the similar preventive effect as the native aFGF on high glucose-induced oxidative stress (increase generation of reactive oxygen species and damage (cellular DNA oxidation, cell hypertrophy, and fibrotic response (increased mRNA expression of fibronectin in three kinds of cells. These in vitro findings were recaptured by examining the heart of the diabetic mice with and without nm-aFGF. CONCLUSIONS: These results suggest that nm-aFGF can prevent diabetic cardiomyopathy, probably through attenuation of cardiac oxidative stress, hypertrophy, and fibrosis.

  1. Low-Dose IL-17 Therapy Prevents and Reverses Diabetic Nephropathy, Metabolic Syndrome, and Associated Organ Fibrosis.

    Diabetes is the leading cause of kidney failure, accounting for >45% of new cases of dialysis. Diabetic nephropathy is characterized by inflammation, fibrosis, and oxidant stress, pathologic features that are shared by many other chronic inflammatory diseases. The cytokine IL-17A was initially implicated as a mediator of chronic inflammatory diseases, but recent studies dispute these findings and suggest that IL-17A can favorably modulate inflammation. Here, we examined the role of IL-17A in diabetic nephropathy. We observed that IL-17A levels in plasma and urine were reduced in patients with advanced diabetic nephropathy. Type 1 diabetic mice that are genetically deficient in IL-17A developed more severe nephropathy, whereas administration of low-dose IL-17A prevented diabetic nephropathy in models of type 1 and type 2 diabetes. Moreover, IL-17A administration effectively treated, prevented, and reversed established nephropathy in genetic models of diabetes. Protective effects were also observed after administration of IL-17F but not IL-17C or IL-17E. Notably, tubular epithelial cell-specific overexpression of IL-17A was sufficient to suppress diabetic nephropathy. Mechanistically, IL-17A administration suppressed phosphorylation of signal transducer and activator of transcription 3, a central mediator of fibrosis, upregulated anti-inflammatory microglia/macrophage WAP domain protein in an AMP-activated protein kinase-dependent manner and favorably modulated renal oxidative stress and AMP-activated protein kinase activation. Administration of recombinant microglia/macrophage WAP domain protein suppressed diabetes-induced albuminuria and enhanced M2 marker expression. These observations suggest that the beneficial effects of IL-17 are isoform-specific and identify low-dose IL-17A administration as a promising therapeutic approach in diabetic kidney disease.

    Claudio Maffeis

    2014-06-01

    Full Text Available Childhood obesity is the metabolic disorder with the highest prevalence in both children and adults. Urgency to treat and prevent childhood obesity is based on the clear evidence that obesity tends to track from childhood to adulthood, is associated to morbidity also in childhood and to long-term mortality. Early life, i.e., intrauterine life and the first two years, is a sensitive window for prevention. Anatomical and functional maturation of the hypothalamic structures devoted to regulating energy intake and expenditure and body size mainly occurs in the first 1,000 days of life. Therefore, factors affecting the foetal exposition to maternal metabolic environment and early postnatal nutrition are crucial in modulating the definition of the metabolic programming processes in the brain. Maternal diseases, mainly malnutrition for defect or excess, obesity and diabetes, placental disorders and dysfunctions, maternal use of alcohol and drugs, smoking, affect long term metabolic programming of the foetus with lifelong consequences. Similarly, early nutrition contributes to complete the long-term metabolic regulating framework initiated in the uterus. Breastfeeding, adequate weaning, attention to portion size and diet composition are potential tools for reducing the obesity risk later in childhood. Longitudinal randomized controlled studies are needed for exploring the efficacy of obesity prevention strategies initiated after conception.Proceedings of the 10th International Workshop on Neonatology · Cagliari (Italy · October 22nd-25th, 2014 · The last ten years, the next ten years in Neonatology Guest Editors: Vassilios Fanos, Michele Mussap, Gavino Faa, Apostolos Papageorgiou

    Keenan, Bernie; Jenkins, Catharine; Ginesi, Laura

    While dementia is an umbrella term for a range of degenerative brain disorders, many share similar presentations. Nurses are ideally placed to identify those at risk and empower them to access treatment and plan and prepare for their future needs--as such, they need up-to-date knowledge of the signs and symptoms of the different types of dementia to identify risk factors and make an informed diagnosis. This article, the third in a four-part series on dementia, examines the risk factors, signs, symptoms and diagnosis of dementia, as well as outlining lifestyle factors such as diet and exercise that may help to prevent the development of the condition.

    Directory of Open Access Journals (Sweden)

    Gabriele Dennert

    Full Text Available BACKGROUND: Selenium is a trace element essential to humans. Higher selenium exposure and selenium supplements have been suggested to protect against several types of cancers. OBJECTIVE: Two research questions were addressed in this review: What is the evidence for: 1. an aetiological relationship between selenium exposure and cancer risk in women and men?; 2. the efficacy of selenium supplementation for cancer prevention in women and men? SEARCH STRATEGY: We searched electronic databases and bibliographies of reviews and included publications. SELECTION CRITERIA: We included prospective observational studies to answer research question (a and randomised controlled trials (RCTs to answer research question (b. DATA COLLECTION AND ANALYSIS: We conducted random effects meta-analyses of epidemiological data when five or more studies were retrieved for a specific outcome. We made a narrative summary of data from RCTs. MAIN RESULTS: We included 49 prospective observational studies and six RCTs. In epidemiologic data, we found a reduced cancer incidence (summary odds ratio, OR, 0.69; 95% confidence interval, CI, 0.53 to 0.91 and mortality (OR 0.55, 95% CI 0.36 to 0.83 with higher selenium exposure. Cancer risk was more pronouncedly reduced in men (incidence: OR 0.66, 95% CI 0.42 to 1.05 than in women (incidence: OR 0.90, 95% CI 0.45 to 1.77. These findings have potential limitations due to study design, quality and heterogeneity of the data, which complicated the interpretation of the summary statistics. The RCTs found no protective efficacy of selenium yeast supplementation against non-melanoma skin cancer or L-selenomethionine supplementation against prostate cancer. Study results for the prevention of liver cancer with selenium supplements were inconsistent and studies had an unclear risk of bias. The results of the Nutritional Prevention of Cancer Trial (NPCT and SELECT raised concerns about possible harmful effects of selenium supplements. AUTHORS

    Preventing the proliferation of weapons of mass destruction is a central part of US national security policy. A principal instrument of the Department of Energy`s (DOE`s) program for securing weapons of mass destruction technology and expertise and removing incentives for scientists, engineers and technicians in the newly independent states (NIS) of the former Soviet Union to go to rogue countries or assist terrorist groups is the Initiatives for Proliferation Prevention (IPP). IPP was initiated pursuant to the 1994 Foreign Operations Appropriations Act. IPP is a nonproliferation program with a commercialization strategy. IPP seeks to enhance US national security and to achieve nonproliferation objectives by engaging scientists, engineers and technicians from former NIS weapons institutes; redirecting their activities in cooperatively-developed, commercially viable non-weapons related projects. These projects lead to commercial and economic benefits for both the NIS and the US IPP projects are funded in Russian, Ukraine, Kazakhstan and Belarus. This booklet offers an overview of the IPP program as well as a sampling of some of the projects which are currently underway.

    Multiple current studies show that neuroinflammation may contribute to mental illness such as depression, anxiety, and mood disorder. Chronic inflammation in peripheral tissues is indicated by the increase of inflammatory marker like cytokine IL-6, TNF-α, and IL-1β. Pro-inflammatory cytokine in peripheral tissues can reach brain tissues and activate microglia and it causes neuroinflammation. Psychological stress may led peripheral and central inflammation. Activated microglia will produce pro-inflammatory cytokine, ROS, RNS, and tryptophan catabolizes. This neuroinflammation can promote metabolism changes of any neurotransmitter, such as serotonin, dopamine, and glutamate that will influence neurocircuit in the brain including basal ganglia and anterior cingulated cortex. It leads to mental illness. Exercise give contribution to reduce tissue inflammation. When muscle is contracting in an exercise, muscle will produce the secretion of cytokine like IL-6, IL-1ra, and IL-10. It will react as anti-inflammation and influence macrophage, T cell, monosit, protein Toll-Like Receptor (TLR), and then reduce neuroinflammation, characterised by the decrease of pro-inflammatory cytokine and prevent the activation of microglia in the brain. The objective of the present study is to review scientific articles in the literature related to the contribution of exercise to prevent and ease mental illness.

    Cellulite is a multifactorial etiology ailment. It changes the skin topography by the formation of the skin surface's appearance, changes described as "orange peel". This prob- lem concerns 85-98% of women, and for them it is one of the most intolerable aesthetic imperfections. In the past few years the interest of scientists in this problem has clearly increased. Several theories on the pathophysiology of cel- lulite have been produced A number of different thera- peutic regimens have been developed using modern tech- nology. However, despite the many treatment options for cellulite, it is extremely important that patients should be aware that only multidirectional treatment can bring sat- isfactory results. The aim of this review was to describe the causes of cellulite, and its prevention and treatment.

    2009-01-01

    Globally an estimated 20 million infants are born with low birthweight (LBW), of those over 18 million are born in developing countries. These LBW infants are at a disproportionately higher risk of mortality, morbidity, poor growth, impaired psychomotor and cognitive development as immediate outcomes, and are also disadvantaged as adults due to their greater susceptibility to type 2 diabetes, hypertension and coronary heart disease. Maternal malnutrition prior to and during pregnancy manifested by low bodyweight, short stature, inadequate energy intake during pregnancy and coexisting micronutrient deficiency are considered major determinants in developing countries where the burden is too high. LBW is a multifactorial outcome and its prevention requires a lifecycle approach and interventions must be continued for several generations. So far, most interventions are targeted during pregnancy primarily due to the increased nutritional demand and aggravations of already existing inadequacy in most women. Several individually successful interventions during pregnancy include balanced protein energy supplementation, several single micro-nutrients or more recently a mix of multiple micronutrients. Nutrition education has been successful in increasing the dietary intake of pregnant women but has had no effect on LBW. The challenge is to identify a community-specific intervention package. Current evidence supports intervention during pregnancy with increased dietary intakes including promotions of foods rich in micronutrients and micronutrient supplementation, preferably with a multiple micronutrient mix. Simultaneously a culturally appropriate educational component is required to address misconceptions about diet during pregnancy and childbirth including support for healthy pregnancy with promotion of antenatal and perinatal care services. While further research is needed to identify more efficacious interventions, an urgent public health priority would be to select and

    Full Text Available The present study was to investigate the protection of resveratrol (RSV in diabetes associated with kidney inflammation and cell proliferation. Rat mesangial cell and streptozotocin-induced type 1 diabetes mouse model were used. In vitro, RSV attenuated high glucose-induced plasminogen activator inhibitor (PAI-1 expression and mesangial cell proliferation, as well as Akt and nuclear factor-kappa B (NF-κB activation. The similar results were recaptured in the experiment with Akt inhibitors. In vivo, mice were divided into three groups: control group, diabetes mellitus (DM group, and RSV-treated DM group. Compared with control group, the kidney weight to body weight ratio and albumin to creatinine ratio were increased in DM group, but not in RSV-treated DM group. Furthermore, the increased expression of PAI-1 and intercellular adhesion molecule-1 in diabetic renal cortex were also reduced by RSV administration. Besides, the kidney p-Akt/Akt ratio and NF-κB were significantly increased in DM group; however, these changes were reversed in RSV-treated DM group. Additionally, immunohistochemistry results indicated that RSV treatment reduced the density of proliferating cell nuclear antigen-positive cells significantly in glomeruli of diabetic mice. These results suggest that RSV prevents diabetes-induced renal inflammation and mesangial cell proliferation possibly through Akt/NF-κB pathway inhibition.

    Preventive medicine plays a central role in the reducing the number of deaths due to preventable causes of premature deaths. General Preventive Medicine Residency programs have not been studied in relation to training in this area. A three-wave mail survey was conducted with email and telephone follow-ups. The outcome measures were the portion of program directors involved in training residents on firearm injury prevention issues and their perceived benefits and barriers of training residents on firearm injury prevention issues. Only 25% of the programs provided formal training on firearm injury prevention. Program directors who provided formal training perceived significantly higher number of benefits to offering such training than did directors who did not provide such training but no significant difference was found between the two for number of perceived barriers. If preventive medicine residency graduates are to play a role in reducing premature morbidity and mortality from firearms it will require more residencies to offer formal training in this area. The Association for Prevention Teaching and Research needs to develop guidelines on specific curriculum topics regarding firearm injury prevention.

    For a very precise analysis of all injured bicyclists in Germany it would be important to have definitions for "severely injured", "seriously injured" and "critically injured". By this, e.g., two-thirds of surgically treated bicyclists who are not registered by the police could become available for a general analysis. Elderly bicyclists (> 60 years) are a minority (10 %) but represent a majority (50 %) of all fatalities. They profit most by wearing a helmet and would be less injured by using special bicycle bags, switching on their hearing aids and following all traffic rules. E-bikes are used more and more (145 % more in 2012 vs. 2011) with 600,000 at the end of 2011 and are increasingly involved in accidents but still have a lack of legislation. So even for pedelecs 45 with 500 W and a possible speed of 45 km/h there is still no legislative demand for the use of a protecting helmet. 96 % of all injured cyclists in Germany had more than 0.5 ‰ alcohol in their blood, 86 % more than 1.1 ‰ and 59 % more than 1.7 ‰. Fatalities are seen in 24.2 % of cases without any collision partner. Therefore the ADFC calls for a limit of 1.1 ‰. Some virtual studies conclude that integrated sensors in bicycle helmets which would interact with sensors in cars could prevent collisions or reduce the severity of injury by stopping the cars automatically. Integrated sensors in cars with opening angles of 180° enable about 93 % of all bicyclists to be detected leading to a high rate of injury avoidance and/or mitigation. Hanging lamps reduce with 35 % significantly bicycle accidents for children, traffic education for children and special trainings for elderly bicyclists are also recommended as prevention tools. As long as helmet use for bicyclists in Germany rates only 9 % on average and legislative orders for using a helmet will not be in force in the near future, coming up campaigns seem to be necessary to be promoted by the Deutscher

    Full Text Available Abstract "No virus, no transmission." Studies have repeatedly shown that viral load (the quantity of virus present in blood and sexual secretions is the strongest predictor of HIV transmission during unprotected sex or transmission from infected mother to child. Effective treatment lowers viral load to undetectable levels. If one could identify and treat all HIV-infected people immediately after infection, the HIV/AIDS epidemic would eventually disappear. Such a radical solution is currently unrealistic. In reality, not all people get tested, especially when they fear stigma and discrimination. Thus, not all HIV-infected individuals are known. Of those HIV-positive individuals for whom the diagnosis is known, not all of them have access to therapy, agree to be treated, or are taking therapy effectively. Some on effective treatment will stop, and in others, the development of resistance will lead to treatment failure. Furthermore, resources are limited: should we provide drugs to asymptomatic HIV-infected individuals without indication for treatment according to guidelines in order to prevent HIV transmission at the risk of diverting funding from sick patients in urgent need? In fact, the preventive potential of anti-HIV drugs is unknown. Modellers have tried to fill the gap, but models differ depending on assumptions that are strongly debated. Further, indications for antiretroviral treatments expand; in places like Vancouver and San Francisco, the majority of HIV-positive individuals are now under treatment, and the incidence of new HIV infections has recently fallen. However, correlation does not necessarily imply causation. Finally, studies in couples where one partner is HIV-infected also appear to show that treatment reduces the risk of transmission. More definite studies, where a number of communities are randomized to either receive the "test-and-treat" approach or continue as before, are now in evaluation by funding agencies. Repeated

    Full Text Available This study is aimed to examine preschool teachers’ knowledge of, attitudes about, and training related to child sexual abuse (CSA prevention in Beijing, China. Two hundred and forty-five preschool teachers were administered the 16-item questionnaire that contained questions on CSA prevention knowledge, attitudes, and teacher training. Results showed that Chinese preschool teachers had limited knowledge on CSA prevention (M = 4.86, SD = 2.12. Less than 5% of the teachers ever attended CSA prevention training programs. Preschool teachers’ training on CSA prevention was the significant factor for their knowledge and attitudes. To help protect children against sexual abuse, there is an urgent need to develop appropriate prevention training programs for preschool teachers in China.

    Although this article is a stand-alone article, it sets the scene for later articles in this issue. Pressure ulcers are considered to be a largely preventable problem, and yet despite extensive training and the expenditure of a large amount of resources, they persist. This article reviews the current understanding of pressure ulcer aetiology: pressure, shear and microclimate. Individual risk factors for pressure ulceration also need to be understood in order to determine the level of risk of an individual. Such an assessment is essential to determine appropriate prevention strategies. The main prevention strategies in terms of reducing pressure and shear and managing microclimate are studied in this article. The problem of pressure ulceration related to medical devices is also considered as most of the standard prevention strategies are not effective in preventing this type of damage. Finally, the possibility of using dressings as an additional preventive strategy is raised along with the question: is there enough evidence to support their use?

    The use of doping is linked with the history of sports. Doping abuse escalated until the mid sixties when government and sports authorities responded with antidoping laws and drug testing. Today, the details of substances detected in controls give a good indication on the importance of doping use. Three classes of pharmaceuticals account for most of the positive controls. They are anabolic steroids, stimulants and narcotics. Their use can be related with the goal of the athletes. Anabolic steroids are mainly used in sports such as bodybuilding or weight lifting in order to develop strength. Stimulants are used in sports were speed favors performance. All the products that enhance blood oxygen transportation are used in endurance sports, their efficacy is not scientifically demonstrated, but their use does result in real risks. Several studies have evidenced the medical problems resulting from prolonged doping. Doping control is impaired by the fact that many products now used, e.g. EPO or rhGH, are not detectable. Regular medical examination of athletes could help prevent use of doping.

    Full Text Available ABSTRACT: Rabies is a zoonotic disease and its magnitude of problem is underestimated due to lack of surveillance. In spite of hundred percent fa tality, the optimistic view is that it is totally and absolutely preventable with the aid of effective post-exposure prophylaxis. It is prevalent mainly in the developing countries like Africa and A sia. Wild carnivorous animals act as reservoir and domestic/peridomestic warm blooded ani mals transmit the virus to the human population. It is popularly known as “Hydrophobia” in h uman and children are at particularly risk. More than 3.3 billion people live in regions w here rabies is enzootic. Dog bite is the principal mode of infection in India and lower limb i s the most common site of injury. Ineffective surveillance, shortage of TCV and Immunoglobulin ma nufacturer and its high cost, peoples ignorance of first aid measures after bite and the importance of compliance of PEP, uncontrolled street dog population etc. are the key issues which should be addressed to tackle this problem.

    Citric acid tablets, which slowly release citric acid when flushed with water, are under development by the Navy for calcification prevention. The citric acid dissolves calcium carbonate deposits and chelates the calcium. For use in urinals, a dispenser is not required because the tablets are non-toxic and safe to handle. The tablets are placed in the bottom of the urinal, and are consumed in several hundred flushes (the release rate can be tailored by adjusting the formulation). All of the ingredients are environmentally biodegradable. Mass production of the tablets on commercial tableting machines was demonstrated. The tablets are inexpensive (about 75 cents apiece). Incidences of clogged pipes and urinals were greatly decreased in long term shipboard tests. The corrosion rate of sewage collection pipe (90/10 Cu/Ni) in citric acid solution in the laboratory is several mils per year at conditions typically found in traps under the urinals. The only shipboard corrosion seen to date is of the yellow brass urinal tail pieces. While this is acceptable, the search for a nontoxic corrosion inhibitor is underway. The shelf life of the tablets is at least one year if stored at 50 percent relative humidity, and longer if stored in sealed plastic buckets.

    1991-01-01

    Full Text Available Listeria monocytogenes is a Gram-positive, rod-shaped bacterium which, although recognized in the medical literature as an opportunistic pathogen for the past 60 years, has only recently gained prominence as an important foodborne pathogen. Factors which make this organism unique among foodborne pathogens include its ability both to survive in foods under a variety of adverse conditions and to grow at low refrigeration temperatures. The organism is very widespread in the environment and can be found in a wide variety of foods. At least four major outbreaks definitively linked to the consumption of food containing L monocytogenes have occurred. In addition there have been a number of recent sporadic cases of listeriosis linked to the consumption of meat, fish and dairy products. The primary concern of the Health Protection Branch is contaminated foods in which L monocytogenes can grow well, and which would not normally be heated prior to consumption. Worldwide, the disease appears to be increasing in incidence, but definite links to foods are difficult to make. In most cases, individuals who come down with listeriosis include the immunocompromised, the elderly (older than 65 years and pregnant women and their fetuses. Primary manifestations of the disease include meningitis, spontaneous abortion and septicemia. Mortality rates in foodborne listeriosis outbreaks are approximately 30%. Diagnosis of listeriosis usually requires isolation of the organism from sterile sites such as blood, cerebrospinal fluid, placenta and meconium and gastric aspirates from neonates. The recommended drug of choice is high dose intravenous ampicillin. Advice to physicians concerning measures to prevent foodborne listeriosis in high risk groups is reviewed. Included among these recommendations is avoidance of consumption of potentially hazardous foods such as soft cheese and raw products of animal origin.

    In 1986, a surgeon who, as an amateur boxer himself was concerned with boxers' health, approached a pioneering Parisian neuroimaging unit. Thus began a study in close cooperation with the French Boxing Federation, spanning 25 years. In a first series of 52 volunteer boxers (13 amateurs and 39 professionals), during which MRI gradually replaced computed tomography, ten risk factors were identified, which notably included boxing style: only one of 40 "stylists" with a good boxing technique had cortical atrophy (4.5 %), compared to 15 % of "sloggers". Changes to the French Boxing Federation rules placed the accent on medical prevention. The second series, of 247 boxers (81 amateurs and 266 professionals), showed a clear improvement, as lesions were suspected in 14 individuals, of which only 4 (1.35 %) were probably due to boxing. The third and fourth series were part of a protocol called "Brain-Boxing-Ageing", which included 76 boxers (11 having suffered KOs) and 120 MRI scans, with reproducible CT and MRI acquisitions (9 sequences with 1.5 T then 3 T, and CT). MRI anomalies secondary to boxing were found in 11 % of amateurs and 38 % of professionals (atrophy, high vascular T2 signal areas, 2 cases of post-KO subdural bleeding). CT revealed sinus damage in 13 % of the amateurs and 19 % of the professionals. The risk of acute and chronic facial and brain damage was underline, along with detailed precautionary measures (organization of bouts, role of the referee and ringside doctor, and application of French Boxing Federation rules).

  8. Prevention of arterial stiffening by using low-dose atorvastatin in diabetes is associated with decreased malondialdehyde.

    Directory of Open Access Journals (Sweden)

    Chih-Hsien Wang

    Full Text Available INTRODUCTION: Without affecting the lipid profile, a low-dose treatment with atorvastatin contributes to the reduction of oxidative stress, inflammation, and adverse cardiovascular events in diabetes. In this study, we investigated whether low-dose atorvastatin exerts any beneficial effect on vascular dynamics in streptozotocin (STZ-induced diabetes in male Wistar rats. METHODS: Diabetes was induced using a single tail-vein injection of STZ at 55 mg kg-1. The diabetic rats were treated daily with atorvastatin (10 mg kg-1 by oral gavage for 6 weeks. They were also compared with untreated age-matched diabetic controls. Arterial wave reflection was derived using the impulse response function of the filtered aortic input impedance spectra. A thiobarbituric acid reactive substances measurement was used to estimate the malondialdehyde content. RESULTS: The high plasma level of total cholesterol in the diabetic rats did not change in response to this low-dose treatment with atorvastatin. Atorvastatin resulted in a significant increase of 15.4% in wave transit time and a decrease of 33.5% in wave reflection factor, suggesting that atorvastatin may attenuate the diabetes-induced deterioration in systolic loads imposed on the heart. This was in parallel with its lowering of malondialdehyde content in plasma and aortic walls in diabetes. Atorvastatin therapy also prevented the diabetes-related cardiac hypertrophy, as evidenced by the diminished ratio of left ventricular weight to body weight. CONCLUSION: These findings indicate that low-dose atorvastatin might protect diabetic vasculature against diabetes-associated deterioration in aorta stiffness and cardiac hypertrophy, possibly through its decrease of lipid oxidation-derived malondialdehyde.

  9. Primary prevention of Down's syndrome

    Directory of Open Access Journals (Sweden)

    2005-07-01

    Full Text Available Background: Antenatal screening has the capacity to detect more than 90% of Down's syndrome pregnancies leading to therapeutic abortion. Successes in recent years with such so-called 'secondary' prevention have not been matched with progress in primary prevention. Despite considerable research over many decades the principle cause of the disorder is unknown. Methods: This paper considers three potential primary prevention strategies, (1 avoiding reproduction at advanced maternal age, (2 pre-implantation genetic diagnosis for couples who are at high risk of Down's syndrome, and (3 folic acid supplementation. The principle aetiological hypotheses are also reviewed. Interpretation: A strategy of completing the family before a maternal age of 30 could more than halve the birth prevalence of this disorder. Women with a high a priori risk should have access to pre-implantation genetic diagnosis, which can lead to a reasonably high pregnancy rate with an extremely low risk of a Down's syndrome. The evidence suggesting an aetiological role for defective folate and methyl metabolism is not sufficient to justify an active preventative strategy of folic acid supplementation without performing a large clinical trial. Current supplementation policies designed to prevent neural tube defects may incidentally prevent Down's syndrome, provided a sufficiently high dose of folic acid is used. Further progress in primary prevention is hampered by limited aetiological knowledge and there is an urgent need to refocus research in that direction.

    Full Text Available A review was conducted to present current views and effectiveness of prevention and rehabilitation methods of hamstring injuries. Methods: a review searching on the electronic data bases, including Proquest, Medline, Sport Discus, Cinahl plus, Health source Nursing / Academic edition, Academic search complete, Pub med and Scholar Google. Only randomized control studies (RCT'S were included which contained the intervention and control groups concerning either the prevention or rehabilitation of hamstrings. Results: fourteen randomized control studies were included. Twelve concerned the prevention and two the rehabilitation of hamstring injuries. From the analysis of the articles concerning prevention we concluded that stretching, especially static and warm up program named "The 11" did not show any benefits in preventing hamstring injuries whilst strength training exercises with eccentric contraction (Nordic exercises and warm-up program "The 11+" containing eccentric exercises of hamstring showed significant differences regarding the prevention. It is postulated that the effectiveness of this may be due to the fact that the researchers had targeted the progressive increase in the intensity and frequency of eccentric exercises. Conclusions: eccentric exercises seem (based on the findings included in this study to have an important role in the prevention and strengthening immediately after hamstring injury and also significantly role on reducing the risk of reinjury. A rehabilitation program that includes mainly stretching exercises with eccentric loading of hamstrings muscles and secondly an exercise program which includes core stability and progressive agility exercises were found to be the most effective for recovery after hamstrings injury.

  2. Insurance and prevention: ethical aspects.

    Science.gov (United States)

    Dubois, Mikael

    2011-02-01

    In recent decades, prevention policies--i.e., insurance policies constructed to give incentives to investments in prevention and thereby reduce reliance on insurance--have been much discussed both with regard to different kinds of market insurance and, albeit primarily within a European context and in relation to an ongoing discussion about the need for a shift towards an "active" welfare state, with regard to social insurance. The present contribution identifies normative issues that deserve attention in relation to a general introduction of prevention policies in market insurance and social insurance. It is argued that the importance of these normative issues suggests that arguments and distinctions drawn from moral and political philosophy should play a more prominent role both in the debate on the shift towards an active welfare state and the use of prevention policies in market insurance.

    Asthma and allergic diseases have become one of the epidemics of the 21st century in developed countries. Much of the success of other areas of medicine, such as infectious diseases, lies on preventive measures. Thus, much effort is also being placed lately in the prevention of asthma and allergy. This manuscript reviews the current evidence, divided into four areas of activity. Interventions modifying environmental exposure to allergens have provided inconsistent results, with multifaceted interventions being more effective in the prevention of asthma. Regarding nutrition, the use of hydrolyzed formulas in high-risk infants reduces the incidence of atopic dermatitis, while there is for now not enough evidence to recommend other dietary modifications, prebiotics, probiotics, or other microbial products. Pharmacologic agents used until now for prevention have not proved useful, while there is hope that antiviral vaccines could be useful in the future. Allergen-specific immunotherapy is effective for the treatment of allergic patients with symptoms; the study of its value for primary and secondary prevention of asthma and allergy is in its very preliminary phases. The lack of success in the prevention of these disorders lies on their complexity, which involves many genetic, epigenetic, and environmental interactions. There is a need to identify target populations, involved mechanisms and interactions, and the best interventions. These must be effective, feasible, implementable, and affordable.

  15. Prevention and dental health services.

    Science.gov (United States)

    Widström, Eeva

    2004-01-01

    There has been, and still is a firm belief that regular use of dental services is beneficial for all. Thus governments in most European countries have shown some interest in training oral health care professionals, distributing the dental workforce and cost sharing. Constantly evolving treatment options and the introduction of new methods make dental clinicians feel uncertain as to which treatments are most useful, who would benefit from them, and which treatments will achieve cost-effective health gain. Although there is a considerable quantity of scientific literature showing that most available preventive measures are effective, and the number of sensible best-practice guidelines in prevention is growing, there are few studies on cost-efficiency of different methods and, secondly, the prevention and treatment guidelines are poorly known among general practitioners. In the eyes of the public, it is obvious that preventive methods practised by patients at home have been eclipsed by clinical procedures performed in dental clinics. Reliance on an increasingly individualistic approach to health care leads to the medicalisation of issues that are not originally health or medical problems. It is important to move general oral disease prevention back to the people who must integrate this in their daily routines. Prevention primarily based on healthy lifestyles, highlighted in the new public health strategy of the European Union (EU), is the key to future health policy.

  16. Prevention Neuroscience: A new frontier for preventive medicine.

    Science.gov (United States)

    Hall, Peter A

    2016-05-01

    Prevention neuroscience may be defined as follows: an interdisciplinary field concerned with the neurobiological factors that influence susceptibility to preventable disease, disability or mortality. It includes, but is not limited to: examination of brain health as an outcome, brain activity as a predictor of health outcomes, brain structures/systems as causal determinants of health outcomes (e.g., health behaviours), and the brain as a mediator of other causal influences (e.g., social conditions) on health outcomes. This commentary describes concepts, theory and research illustrating each of these scenarios using exercise, smoking cessation, dietary behaviour, and health disparities as examples. It is argued that neuroscience may provide both concepts and methods that may be possible (even fruitful) to incorporate into preventive medicine research and health promotion practise. Although public health practitioners and cognitive neuroscientists have not traditionally crossed paths outside of the context of neurodegenerative diseases such as Alzheimer's and other dementias, it is easy to envision a future where many common disease prevention activities involve collaboration between the two disciplines, and the cache of tools available to the preventive medicine expert includes neuroimaging and neuromodulation techniques.

    Full Text Available The paper presents the money laundering and terrorist financing prevention system in Croatia. The basic concepts are defined, the principles and fundamentals of international regulations analysed, and the regulatory system in Croatia covered by statute and money laundering prevention Regulations is presented, in conjunction with a description of the organisation, remit and international actions of the Money Laundering Prevention Office.The infiltration of dirty money is a crucial problem from national economies. The purchase of shares, of real estate, the establishment of dirty investment funds and the use of the banking system for the embedding of such resources is a danger to the credibility of a whole country, and in particular to the security of the financial and banking system. Croatia has adopted statutory measures aimed at the effective detection and prevention of suspicious financial transactions, in other words the prevention of money laundering.Launderers constantly find new ways, make use of new non-financial channels and expand their activities to real estate, artworks and insurance. Hence it is necessary to keep up with European approaches and recommendations, to strive for further improvement of the laws and the modernisation of the system, and to adopt new regulations harmonised with international standards, particularly with Directive 2005/60/EC.

    Women may expect to spend more than a third of their lives after menopause. Beginning in the sixth decade, many chronic diseases will begin to emerge, which will affect both the quality and quantity of a woman's life. Thus, the onset of menopause heralds an opportunity for prevention strategies to improve the quality of life and enhance longevity. Obesity, metabolic syndrome and diabetes, cardiovascular disease, osteoporosis and osteoarthritis, cognitive decline, dementia and depression, and cancer are the major diseases of concern. Prevention strategies at menopause have to begin with screening and careful assessment for risk factors, which should also include molecular and genetic diagnostics, as these become available. Identification of certain risks will then allow directed therapy. Evidence-based prevention for the diseases noted above include lifestyle management, cessation of smoking, curtailing excessive alcohol consumption, a healthy diet and moderate exercise, as well as mentally stimulating activities. Although the most recent publications from the follow-up studies of the Women's Health Initiative do not recommend menopause hormonal therapy as a prevention strategy, these conclusions may not be fully valid for midlife women, on the basis of the existing data. For healthy women aged 50-59 years, estrogen therapy decreases coronary heart disease and all-cause mortality; this interpretation is entirely consistent with results from other randomized, controlled trials and observational studies. Thus. as part of a comprehensive strategy to prevent chronic disease after menopause, menopausal hormone therapy, particularly estrogen therapy may be considered as part of the armamentarium.

    2015-01-01

    Prosthetic joint infection (PJI) is a calamitous complication with high morbidity and substantial cost. The reported incidence is low but it is probably underestimated due to the difficulty in diagnosis. PJI has challenged the orthopaedic community for several years and despite all the advances in this field, it is still a real concern with immense impact on patients, and the healthcare system. Eradication of infection can be very difficult. Therefore, prevention remains the ultimate goal. The medical community has executed many practices with the intention to prevent infection and treat it effectively when it encounters. Numerous factors can predispose patients to PJI. Identifying the host risk factors, patients’ health modification, proper wound care, and optimizing operative room environment remain some of the core fundamental steps that can help minimizing the overall incidence of infection. In this review we have summarized the effective prevention strategies along with the recommendations of a recent International Consensus Meeting on Surgical Site and Periprosthetic Joint Infection.

    Teenage pregnancy is associated with many health, emotional and socioeconomic problems including higher rates of anemia, labor complications, mortality, legal and social struggles and hhigher divorce rates. Professional social workers need strategies to help teenagers avoid early, unwanted pregnancy. This paper offers promising experential and research backing for a primary prevention group work strategy for all adolescents. Social and health programs overlook educational, cognitive anc interpersonal factors biasing youths' ability to comprehend and regulate contraception. Primary prevention to assist adolescents in thinking analytically about their sexual behavior must stress problem solving and decision-making as well as facts about human reproduction and birth control. To implement decisions, youths also need interpersonal communication skills. Small groups are ideal for delivering cognitive-behavioral primary prevention. This approach is based on the premise that youths become pregnant not because of a lack of relevant information, but because they lack cognitive and behavioral skills necessary to use information. Group work involving role-playing helps develop communication skills. Results from 2 field studies describe short-term and longitudinal benefits of the prevention strategy. Professionals can reach significant numbers of youth in this way. By treating sexual issues and the risk of pregnancy as normal in adolescence, social workers can introduce information and pertinent skills to all teenagers. No one is singled out as deviant and the group format enables young people to discuss taboo topics, discovering what the norms are and gradually learning how to deal with peers, family members, techers and others. Adolescents in primary prevention groups gained knowledge, cognitive skills and communication acumen. Improved attitudes toward family planning, increased regular contraception and less unsafe sex resulted from this cognitive-behavioral approach

    The refeeding syndrome can be defined as the metabolic alterations developed by the rapid nutrition repletion (oral, enteral as well as parenteral feeding) of severaly malnourished patients. Refeeding syndrome is a potentially fatal clinical condition and it is often underdiagnosed on non-specialized nutrition units. The most important key for its prevention is to identify patients at high risk for developing refeeding syndrome, before nutrition repletion. The present case describes the steps to prevent the refeeding syndrome as well as the clinical recommendations to restart nutrition support.

    Martín Jiménez, Juan Antonio; Consuegra Moya, Belkis; Martín Jiménez, María Teresa

    2015-07-18

    Osteoporosis, main risk factor for suffering fragility fractures, is an important public health problem which has undoubted social, health and economic impact; but mainly causes pain, functional limitation and severe alterations in the patient's quality of life. Its current prevalence is very high and a further increase is expected due to a higher life expectancy and the progressive ageing of the population. In the prevention of osteoporosis, the main goal is to prevent fragility fractures; for this reason, it is necessary to: 1) promote bone formation in youth, to get sufficient bone mass peak, 2) reduce bone loss in adulthood, especially after menopause, 3) maintain bone health throughout life, and 4) prevent falls. There is enough evidence that multifactorial strategies (assessment of risk factors, healthy lifestyle habits, smoking cessation, moderation in alcohol consumption, physical exercise, outdoor activity with prudent exposure to sunlight, and a varied and balanced diet), are effective in the population at risk. Regarding factors for the prevention of osteoporosis, current recommendations are: increased consumption of calcium, phosphorus, magnesium and fluoride; provide adequate vitamin D (even with fortified food if necessary); consumption of foods rich in omega-3 acids; reduction of salt and prepared ready meals; sufficient but moderate intake of protein and, in the absence of intolerance, promote the consumption of milk and dairy products, especially yogurt and fermented milk products.

  20. Prevention of occupational Back Pain

    Directory of Open Access Journals (Sweden)

    Sultan T Al-Otaibi

    2015-01-01

    Full Text Available This paper reviews scientific research on occupational back pain and focuses on prevention of this problem. It discusses some of the challenges of translating the evidence of this multi-factorial condition into policy. Medical science is currently unable to clearly distinguish between back pain caused by work and that possibly due to other causes but which affects the individual′s capacity to work. Back pain affects the vast majority of people at some point in their lives and is very costly to both the health care system and the industry. Evidence suggests that heavy lifting, driving, and vibration of the whole body are linked to occupational back pain. Once the risk factors for occupational back pain are identified, an otherwise chronic and disabling condition can be prevented in the majority of patients.

Failure to implement preventive measures may lead to a high incidence of occupational back pain.

    2005-06-01

    A wide range of head and neck injury risks are present in sport, including catastrophic injury. The literature since 1980 on prevention of head and neck injury in sport was reviewed, focusing on catastrophic and brain injury and identifying the range of injury prevention methods in use. There have been few formal evaluations of injury prevention methods. Approaches that are considered, or have been proven, to be successful in preventing injury include: modification of the baseball; implementation of helmet standards in ice hockey and American football and increased wearing rates; use of full faceguards in ice hockey; changes in rules associated with body contact; implementation of rules to reduce the impact forces in rugby scrums. Helmets and other devices have been shown to reduce the risk of severe head and facial injury, but current designs appear to make little difference to rates of concussion. Research methods involving epidemiological, medical, and human factors are required in combination with biomechanical and technological approaches to reduce further injury risks in sport.

    Full Text Available Background: An ageing population, a growing prevalence of chronic diseases and limited financial resources for health care underpin the importance of prevention of disabling health disorders and care dependency in the elderly. A wide variety of measures is generally available for the prevention of falls and fall-related injuries. The spectrum ranges from diagnostic procedures for identifying individuals at risk of falling to complex interventions for the removal or reduction of identified risk factors. However, the clinical and economic effectiveness of the majority of recommended strategies for fall prevention is unclear. Against this background, the literature analyses in this HTA report aim to support decision-making for effective and efficient fall prevention.Research questions: The pivotal research question addresses the effectiveness of single interventions and complex programmes for the prevention of falls and fall-related injuries. The target population are the elderly (> 60 years, living in their own housing or in long term care facilities. Further research questions refer to the cost-effectiveness of fall prevention measures, and their ethical, social and legal implications. Methods: Systematic literature searches were performed in 31 databases covering the publication period from January 2003 to January 2010. While the effectiveness of interventions is solely assessed on the basis of randomised controlled trials (RCT, the assessment of the effectiveness of diagnostic procedures also considers prospective accuracy studies. In order to clarify social, ethical and legal aspects all studies deemed relevant with regard to content were taken into consideration, irrespective of their study design. Study selection and critical appraisal were conducted by two independent assessors. Due to clinical heterogeneity of the studies no meta-analyses were performed.Results: Out of 12,000 references retrieved by literature searches, 184 meet the

    2015-11-23

    Pancreatic cancer is without any doubt the malignancy with the poorest prognosis and the lowest survival rate. This highly aggressive disease is rarely diagnosed at an early stage and difficult to treat due to its resistance to radiotherapy and chemotherapy. Therefore, there is an urgent need to clarify the causes responsible for pancreatic cancer and to identify preventive strategies to reduce its incidence in the population. Some circumstances, such as smoking habits, being overweight and diabetes, have been identified as potentially predisposing factors to pancreatic cancer, suggesting that diet might play a role. A diet low in fat and sugars, together with a healthy lifestyle, regular exercise, weight reduction and not smoking, may contribute to prevent pancreatic cancer and many other cancer types. In addition, increasing evidence suggests that some food may have chemo preventive properties. Indeed, a high dietary intake of fresh fruit and vegetables has been shown to reduce the risk of developing pancreatic cancer, and recent epidemiological studies have associated nut consumption with a protective effect against it. Therefore, diet could have an impact on the development of pancreatic cancer and further investigations are needed to assess the potential chemo preventive role of specific foods against this disease. This review summarizes the key evidence for the role of dietary habits and their effect on pancreatic cancer and focuses on possible mechanisms for the association between diet and risk of pancreatic cancer.

  20. Childhood obesity, prevalence and prevention

    Directory of Open Access Journals (Sweden)

    2005-09-01

    Full Text Available Abstract Childhood obesity has reached epidemic levels in developed countries. Twenty five percent of children in the US are overweight and 11% are obese. Overweight and obesity in childhood are known to have significant impact on both physical and psychological health. The mechanism of obesity development is not fully understood and it is believed to be a disorder with multiple causes. Environmental factors, lifestyle preferences, and cultural environment play pivotal roles in the rising prevalence of obesity worldwide. In general, overweight and obesity are assumed to be the results of an increase in caloric and fat intake. On the other hand, there are supporting evidence that excessive sugar intake by soft drink, increased portion size, and steady decline in physical activity have been playing major roles in the rising rates of obesity all around the world. Consequently, both over-consumption of calories and reduced physical activity are involved in childhood obesity. Almost all researchers agree that prevention could be the key strategy for controlling the current epidemic of obesity. Prevention may include primary prevention of overweight or obesity, secondary prevention or prevention of weight regains following weight loss, and avoidance of more weight increase in obese persons unable to lose weight. Until now, most approaches have focused on changing the behaviour of individuals in diet and exercise. It seems, however, that these strategies have had little impact on the growing increase of the obesity epidemic. While about 50% of the adults are overweight and obese in many countries, it is difficult to reduce excessive weight once it becomes established. Children should therefore be considered the priority population for intervention strategies. Prevention may be achieved through a variety of interventions targeting built environment, physical activity, and diet. Some of these potential strategies for intervention in children can be

  1. [Clinical psychiatry and suicide prevention].

    People do not commit suicide all of a sudden. There is a suicidal process where negative life events are there in the beginning, and social support and help-seeking behavior play an important role in impeding the progress of the process. Mental disturbance would be deeply associated with the suicidal process around the final stage, thinking of the fact that approximately 90% of the suicides suffered from mental disorders at the time of suicide. In considering the strategies for suicide prevention, there are two perspectives: a community model and a medical model. A community model is thought to be related mainly to the first half of the suicidal process and a medical model to the latter half. It is an ideal that both community and medical approaches are put into practice simultaneously. However, if resources available for suicide prevention are limited, a medical-model approach would be more efficient and should be given priority. Starting from a medical model and considering treatment and social resources necessary for suicidal people, the range of suicide prevention activities would be expand more efficiently than starting from a community-model approach. Clinical psychiatry plays a greatly important role in preventing suicide. It is found that approximately 20% of seriously injured suicide attempters were diagnosed as adjustment disorder in Japan, which means that even the mildly depressed can commit suicide. Therefore, no one can take a hands-off approach to suicidality as long as he/she works in the field of clinical psychiatry. It is earnestly desired to detect and treat properly the suicidal patients, but there is no perfect method. It would be helpful to pay attention to patients' personality development, stress-coping style and present suicidal ideation. Besides, as suicide prevention is not completed only in a consulting room, it is important for psychiatrists to look for teamwork.

    ) phosphorylation levels was noteworthy higher than that of other two groups(P <0. 05). Meanwhile, the results also showed that insulin receptor subtype 1 (IR1) expression was down-regulated(P <0.05)and PI3K-Akt signal cascades were inactivated. Correspondingly, swimming exercise could decline the ratio of Bax/Bcl-2, considerably improve the survival pathway and further activate GSK-3β protein phosphorylation { P < 0. 05 ). In addition, swimming exercise also could augment insulin receptor IR1 (P < 0.05) contents. Although the level of IR2 was enhanced, there is no divergence for statistics. Conclusion; Swim training can effectively inhibit type 2 diabetes-induced myocardial apoptosis in Wistar rats. This anti-apoptotic effect may be through, at least in part, increasing the contents of IR1 receptor, and thereby activate PI3K-Akt signal cascade and further decline the phosphorylation expression of its key downstream of protein-GSK-3β, suggesting that swimming training may be an appropriate modality for combating with myocardial cell damage caused by T2DM.

    Diabetes-induced oxidative stress plays a critical role in the mobilisation of endothelial progenitor cells (EPCs) from the bone marrow to the circulation.This study was designed to explore the effects of chronic melatonin administration on the promotion of the mobilisation of EPCs and on the preservation of erectile function in type Ⅰ diabetic rats.Melatonin was administered to streptozotocin-induced type Ⅰdiabetic rats.EPCs levels were determined using flow cytometry,Oxidative stress in the bone marrow was indicated by the levels of superoxide dismutase and malondialdehyde.Erectile function was evaluated by measuring the intracavemous pressure during an electrostimulation of the cavernous nerve.The density of the endothelium and the proportions of smooth muscle and collagen in the corpus cavernosum were determined by immunohistochemistry.The administration of melatonin increased the superoxide dismutase level and decreased the malondiaidehyde level in the bone marrow,This effect was accompanied by an increased level of circulating EPCs in the diabetic rats.The intracavernous pressure to mean arterial pressure ratio of the rats in the treatment group was significantly greater,compared with diabetic control rats.The histological analysis demonstrated an increase in the endothelial density of the corpus cavernosum after the administration of melatonin.However,melatonin treatment did not change the proportions of smooth muscle and collagen in the corpus cavernosum of diabetic rats.Chronic administration of melatonin has a beneficial effect on preventing erectile dysfunction (ED) in type Ⅰ diabetic rats.Promoting the mobilisation of EPCs is one of the possible mechanisms involved in the improvement of ED.

    Full Text Available Health political background: In 2006, the prevalence of overweight and adiposity among children and adolescents aged three to 17 years is 15%, 6.3% (800,000 of these are obese. Scientific background: Obese children and adolescents have an increased body fat ratio. The reasons for overweight are – among others – sociocultural factors, and a low social status as determined by income and educational level of the parents. The consequences of adiposity during childhood are a higher risk of metabolic and cardiovascular diseases and increased mortality in adulthood. Possible approaches to primary prevention in children and adolescents are measures taken in schools and kindergarten, as well as education and involvement of parents. Furthermore, preventive measures geared towards changing environmental and living conditions are of particular importance. Research questions: What is the effectiveness and efficiency of different measures and programs (geared towards changing behaviour and environmental and living conditions for primary prevention of adiposity in children and adolescents, with particular consideration of social aspects? Methods: The systematic literature search yielded 1,649 abstracts. Following a two-part selection process with predefined criteria 31 publications were included in the assessment. Results: The majority of interventions evaluated in primary studies take place in schools. As the measures are mostly multi-disciplinary and the interventions are often not described in detail, no criteria of success for the various interventions can be extrapolated from the reviews assessed.

    Pettifor, John M

    2013-06-01

    Nutritional rickets remains a public health concern in many areas of the world despite cheap and effective means of preventing the disease. The roles of vitamin D deficiency, low dietary calcium intakes and the interrelationships between the two in the pathogenesis of the disease are discussed. It is now recognized that vitamin D deficiency in the pregnant and lactating mother predisposes to the development of rickets in the breastfed infant, and that cultural and social factors are important in the pathogenesis of the disease during the adolescent growth spurt. Prevention of rickets is dependent on the awareness of the medical profession and the general public of the need to ensure adequate intakes of vitamin D in at-risk populations, and of the importance of increasing dietary intakes of calcium using locally available and inexpensive foods in communities in which dietary calcium deficiency rickets is prevalent.

    Kerschan-Schindl, Katharina

    2016-02-01

    Osteoporosis is a frequent disease in postmenopausal women. Despite the fact that fragility fractures cause many problems, osteoporosis is still underdiagnosed and undertreated. This manuscript outlines the topics diagnosis of osteoporosis, fracture risk prevention, and therapy after fracture. Regular physical activities, a sufficient intake of calcium, and a normal vitamin D level are important for bone health. Depending on the personal fracture risk, the patient may also be prescribed bone-specific medication to prevent fragility fractures. In case of a prevalent osteoporotic fracture, the initiation or adaptation of bone-specific therapy is indispensable. Since most osteoporotic fractures occur during a fall, fall risk reduction is an important measure to inhibit a new fracture. Rehabilitation of patients with fragility fractures varies with different localizations of the fracture and should be performed by a multidisciplinary team.

    2007-01-01

    Visual cryptography (VC) is a method of encrypting a secret image into shares such that stacking a sufficient number of shares reveals the secret image. Shares are usually presented in transparencies. Each participant holds a transparency. Most of the previous research work on VC focuses on improving two parameters: pixel expansion and contrast. In this paper, we studied the cheating problem in VC and extended VC. We considered the attacks of malicious adversaries who may deviate from the scheme in any way. We presented three cheating methods and applied them on attacking existent VC or extended VC schemes. We improved one cheat-preventing scheme. We proposed a generic method that converts a VCS to another VCS that has the property of cheating prevention. The overhead of the conversion is near optimal in both contrast degression and pixel expansion.

    2015-04-01

    The incidence of oesophageal adenocarcinoma has risen rapidly over the past four decades. Unfortunately, treatments have not kept pace; unless their cancer is identified at a very early stage, most patients will not survive a year after diagnosis. The beginnings of this widespread problem were first recognized over 25 years ago, yet rates have continued to rise against a backdrop of much improved understanding and management of oesophageal adenocarcinoma. We estimate that only ∼7% of the 10,000 cases of oesophageal adenocarcinoma diagnosed annually in the USA are identified through current approaches to cancer control, and trace pathways by which the remaining 93% are 'lost'. On the basis of emerging data on aetiology and predictive factors, together with new diagnostic tools, we suggest a five-tier strategy for prevention and control that begins with a wide population base and triages individuals into progressively higher risk strata, each with risk-appropriate prevention, screening and treatment options.

    Unlike other natural hazards, earthquakes strike suddenly and without warning. Consequently, prevention is the best we can do to ensure safety. In spite of the large and medium earthquakes, some of them tsunamigenic, that affected Portugal in the past, the Portuguese society is little aware of the seismic risk and has not developed an adequate culture of prevention. This is most probably due to the long time interval between destructive earthquakes. Earthquakes can be a real danger to societies, damaging human-made structures and endangering human lives. Earthquakes can trigger additional emergencies, and individuals should also be prepared to contend with it. By planning and practicing what to do if an earthquake strikes, children and their family can learn to react correctly and automatically when the shaking begins. Risks can then be dramatically lessened if the population is educated on how to react before, during and after an earthquake. Children's knowledge is ever growing. They have a fundamental role in changing societies. By educating the children of today we are forming better adults of tomorrow. We are simultaneously passing this knowledge to their caregivers and families. Through demonstrating how fundamental it is to be conscious of those issues, not only will the children will be informed, but also their relatives will be aware of such risks. We use this approach to explain children how to assess risk in a broader sense. We teach them other preventive measures, namely those related with electricity, gas and the danger on non-potable water, essential topics on "what to do before an earthquake" but also on the daily routines. This presentation will highlight the importance of encouraging a culture of prevention.

  17. A performative definition of waste prevention.

    Science.gov (United States)

    Corvellec, Hervé

    2016-06-01

    The increasing importance being placed on waste prevention in European waste governance raises the question of how waste prevention is defined in practice. This paper presents a qualitative analysis of a sample of fifty-one Swedish waste prevention initiatives with the purpose of identifying which kind of actions are imagined, promoted, and set into motion under the label of waste prevention. The analysis shows that despite their apparent variety, the initiatives in the sample boil down to three main types of actions: raising awareness about the need to prevent waste, increasing material efficiency, and developing sustainable consumption. In contradistinction to the formal definition of waste prevention in the European Waste Framework Directive (2008/98/EC), what emerges from analyzing the initiatives in the sample is a performative definition of waste prevention as something heterogeneous, contradictory, and evolving. Such a definition of waste prevention in practice provides an understanding of the organizational dynamics of waste prevention.

    Restenosis remains the major limitation of percutaneous transluminal coronary angioplasty. Restenosis after balloon angioplasty is due to vascular remodeling and neointimal hyperplasia. In spite of encouraging results in animal models, most of the pharmacological trials of prevention of restenosis in humans have produced negative results. This has prompted interest in the potential role of locally delivered drugs and various balloon catheter systems that are now available to achieve local delivery of therapeutic agents at the site of arterial injury. In 1997, implantation of a coronary stent in conjunction with balloon angioplasty is performed in an increasing number of patients. Randomized studies have shown that coronary stenting may reduce the risk of restenosis. In addition, restenosis after coronary stenting is mainly due to neointimal hyperplasia. Restenosis within coronary stents might thus be much more sensitive to therapies designed to inhibit neointimal hyperplasia than restenosis after balloon angioplasty. Thus, the future prevention of restenosis might well be the combination of a mechanical device that produces the widest possible lumen and prevents vessel constriction with a pharmacologic approach to inhibit the proliferative process.

  19. New technology for accident prevention

    Energy Technology Data Exchange (ETDEWEB)

    Byne, P. [Shiftwork Solutions, Vancouver, BC (Canada)

    2006-07-01

    This power point presentation examined the effects of fatigue in the workplace and presented 3 technologies designed to prevent or monitor fatigue. The relationship between mental fatigue, circadian rhythms and cognitive performance was explored. Details of vigilance related degradations in the workplace were presented, as well as data on fatigue-related accidents and a time-line of meter-reading errors. It was noted that the direct cause of the Exxon Valdez disaster was sleep deprivation. Fatigue related accidents during the Gulf War were reviewed. The effects of fatigue on workplace performance include impaired logical reasoning and decision-making; impaired vigilance and attention; slowed mental operations; loss of situational awareness; slowed reaction time; and short cuts and lapses in optional or self-paced behaviours. New technologies to prevent fatigue-related accidents include (1) the driver fatigue monitor, an infra-red camera and computer that tracks a driver's slow eye-lid closures to prevent fatigue related accidents; (2) a fatigue avoidance scheduling tool (FAST) which collects actigraphs of sleep activity; and (3) SAFTE, a sleep, activity, fatigue and effectiveness model. refs., tabs., figs.

  20. SATURATED PICRIC ACID PREVENTS AUTOPHAGIA

    Full Text Available "nThe dysesthesia and paresthesia that occurs in laboratory rats after spinal cord injury (SCI results in autophagia. This self-destructive behavior interferes with functional assessments in designed studies and jeopardizes the health of the injured rat. In this study, we evaluated role of saturated picric acid in the prevention of autophagia and self-mutilation. All rats were anesthetized with an intraperitoneal injection of a mixture of ketamine (100 mg/kg and xylazine (10 mg/kg for the SCI procedures. In the first 39 rats, no solution applied to the hind limbs, but in the next 26 cases, we smeared the saturated picric acid on the tail, lower extremities, pelvic, and abdomen of the rats immediately after SCI. In the rats without picric acid, 23 rats died following autophagia, but in the 26 rats with picric acid, there was no autophagia (P < 0.001. Picric acid side effects in skin and gastrointestinal signs such as irritation, redness and diarrhea were not seen in any rat. Saturated picric acid is a topical solution that if used appropriately and carefully, might be safe and effectively prevents autophagia and self-mutilation. When the solution is applied to the lower abdomen and limbs, we presume that its bitterness effectively prevents the rat from licking and biting the limb.

  1. Type 1 diabetes pathogenesis - Prevention???

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Pathogenesis of type 1 diabetes is multi-faceted, including, autoimmunity, genetics and environment. Autoimmunity directed against pancreatic islet cells results in slowly progressive selective beta-cell destruction ("Primary autoimmune insulitis", culminating over years in clinically manifested insulin-dependent diabetes mellitus (IDDM. Circulating serum autoantibodies directed against the endocrine cells of the islets of Langerhans (Islet cell autoantibodies - ICAb are an important hallmark of this disease. Assays for islet cell autoantibodies have facilitated the investigation and understanding of several facets in the pathogenesis of autoimmune diabetes. Their applications have extended into clinical practice and have opened new avenues for early preclinical prediction and preventive prophylaxis in IDDM/type 1 DM. Recently, surprisingly, differences in insulin content between T1DM islets, as well as, ′patchy′ or ′lobular′ destruction of islets have been described. These unique pathobiological phenomena, suggest that beta cell destruction may not always be inexorable and inevitably complete/total, and thus raise hopes for possible therapeutic interruption of beta cell autoimmunity - destruction and cure of type 1 diabetes. "Recurrent or secondary autoimmune insulitis" refers to the rapid reappearance of islet cell autoantibodies post pancreas transplant, and selective islet beta cell destruction in the grafted pancreas [never forgetting or "anamnestic" beta cell destructive memory], in the absence of any graft pancreas rejection [monozygotic twin to twin transplantation]. The one definite environmental factor is congenital rubella, because of which a subset of children subsequently develop type 1 diabetes. The putative predisposing factors are viruses, gluten and cow′s milk. The putative protective factors include gut flora, helminths, viral infections, and Vitamin D. Prevention of T1DM can include: Primary prevention strategies

    2013-06-01

    Further understanding of educators' views of eating disorder prevention can further engage them in this effort. No previous studies of educators have used acceptability methodology or compared eating disorder prevention to other prevention efforts. Educators (n = 135) rated the acceptability of five sample programs and provided their opinions about eating disorder and other prevention programs. The results indicated primarily psychoeducational and general well-being programs were most acceptable. Educators-specified trained professionals should implement programs during school hours to male and female junior high students. Although eating disorder prevention was perceived as important, it was not rated as vital as other programs, such as substance abuse prevention.

    Mendelson, Tamar; Tandon, S Darius

    2016-04-01

    This article discusses strategies and programs used to prevent depression in children and adolescents. It describes the rationale for depression prevention and discusses prevention approaches in schools and other settings, highlighting examples of programs that have been empirically evaluated. Prevention effects are small but significant, comparable or greater in magnitude than adolescent prevention programs for other issues, including substance use and human immunodeficiency virus. Future research should include rigorous design features, including attention control groups, allocation concealment, larger sample sizes, longer follow-up assessments, and theory-driven tests of moderation and mediation, and should test larger-scale implementation of prevention programs.

    The Department of Energy (DOE) has established a national Research, Development, Demonstration, Testing, and Evaluation (RDDT&E) Program for pollution prevention and waste minimization at its production plants During FY89/90 the Office of Environmental Restoration and Waste Management (EM), through the Office of Technology Development (OTD), established comprehensive, pollution prevention technical support programs to demonstrate new, environmentally-conscious technology for production processes. The RDDT&E program now entails collaborative efforts across DOE. The Pollution Prevention Program is currently supporting three major activities: The DOE/US Air Force Memorandum of Understanding Program is a collaborative effort to utilize the combined resources of DOE and the Department of Defense, eliminate duplication of effort in developing technologies, and to facilitate technology solutions aimed at reducing waste through process modification, material substitution or recycling. The Waste Component Recycle, Treatment and Disposal Integrated Demonstration (WeDID) will develop recycle, treatment, and disposal processes and associated technologies for use in the dismantlement of non-nuclear weapons components, to support US arms treaties and policies. This program will focus on meeting all security and regulatory requirements (with additional benefit to the commercial electronics industry). The Environmentally Conscious Manufacturing Integrated Demonstration (ECMID) will effectively implement ECM technologies that address both the needs of the DOE Complex and US electronics industry, and encourage strong interaction between DOE and US industry. The ECMID will also develop life cycle analysis tools that will aid decisionmakers in selecting the optimum process based on the tradeoffs between cost an environmental impact.

  1. Hepatocellular carcinoma: Therapy and prevention

    Institute of Scientific and Technical Information of China (English)

    Hubert E Blum

    2005-01-01

    Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. The major etiologies and risk factors for the development of HCC are well defined and some of the multiple steps involved in hepatocarcinogenesis have been elucidated in recent years. Despite these scientific advances and the implementation of measures for the early detection of HCC in patients at risk, patient survival has not improved during the last three decades. This is due to the advanced stage of the disease at the time of clinical presentation and limited therapeutic options. The therapeutic options fall into five main categories: surgical interventions including tumor resection and liver transplantation, percutaneous interventions including ethanol injection and radiofrequency thermal ablation, transarterial interventions including embolization and chemoembolization, radiation therapy and drugs as well as gene and immune therapies. These therapeutic strategies have been evaluated in part in randomized controlled clinical trials that are the basis for therapeutic recommendations. Though surgery, percutaneous and transarterial interventions are effective in patients with limited disease (1-3 lesions, <5 cm in diameter) and compensated underlying liver disease (cirrhosis Child A), at the time of diagnosis more than 80% patients present with multicentric HCC and advanced liver disease or comorbidities that restrict the therapeutic measures to best supportive care. In order to reduce the morbidity and mortality of HCC, early diagnosis and the development of novel systemic therapies for advanced disease, including drugs, gene and immune therapies as well as primary HCC prevention are of paramount importance. Furthermore, secondary HCC prevention after successful therapeutic interventions needs to be improved in order to make an impact on the survival of patients with HCC. New technologies, including gene expression profiling and proteomic analyses, should allow to further

    2016-07-01

    Dystocia is an inevitable challenge in the livestock industries, particularly with primiparous female animals. Prevention and appropriate management will decrease cow and calf morbidity and mortality, which will improve the economic status of the beef or dairy operation. Early identification and proper intervention improves outcomes, and the use of selection tools to decrease the potential for dystocia will have positive returns. Assisted reproductive technologies present a unique set of challenges to the calving process that both the producer and practitioner should be prepared to address.

  3. Oral cleft prevention program (OCPP

    Directory of Open Access Journals (Sweden)

    Wehby George L

    2012-11-01

    Full Text Available Abstract Background Oral clefts are one of the most common birth defects with significant medical, psychosocial, and economic ramifications. Oral clefts have a complex etiology with genetic and environmental risk factors. There are suggestive results for decreased risks of cleft occurrence and recurrence with folic acid supplements taken at preconception and during pregnancy with a stronger evidence for higher than lower doses in preventing recurrence. Yet previous studies have suffered from considerable design limitations particularly non-randomization into treatment. There is also well-documented effectiveness for folic acid in preventing neural tube defect occurrence at 0.4 mg and recurrence with 4 mg. Given the substantial burden of clefting on the individual and the family and the supportive data for the effectiveness of folic acid supplementation as well as its low cost, a randomized clinical trial of the effectiveness of high versus low dose folic acid for prevention of cleft recurrence is warranted. Methods/design This study will assess the effect of 4 mg and 0.4 mg doses of folic acid, taken on a daily basis during preconception and up to 3 months of pregnancy by women who are at risk of having a child with nonsyndromic cleft lip with/without palate (NSCL/P, on the recurrence of NSCL/P. The total sample will include about 6,000 women (that either have NSCL/P or that have at least one child with NSCL/P randomly assigned to the 4 mg and the 0.4 mg folic acid study groups. The study will also compare the recurrence rates of NSCL/P in the total sample of subjects, as well as the two study groups (4mg, 0.4 mg to that of a historical control group. The study has been approved by IRBs (ethics committees of all involved sites. Results will be disseminated through publications and presentations at scientific meetings. Discussion The costs related to oral clefts are high, including long term psychological and socio-economic effects. This study

    2013-09-01

    Full Text Available Jeffrey A Russell Division of Athletic Training, School of Applied Health Sciences and Wellness, Ohio University, Athens, OH, USA Abstract: Dancers are clearly athletes in the degree to which sophisticated physical capacities are required to perform at a high level. The standard complement of athletic attributes – muscular strength and endurance, anaerobic and aerobic energy utilization, speed, agility, coordination, motor control, and psychological readiness – all are essential to dance performance. In dance, as in any athletic activity, injuries are prevalent. This paper presents the research background of dance injuries, characteristics that distinguish dance and dancers from traditional sports and athletes, and research-based perspectives into how dance injuries can be reduced or prevented, including the factors of physical training, nutrition and rest, flooring, dancing en pointe, and specialized health care access for dancers. The review concludes by offering five essential components for those involved with caring for dancers that, when properly applied, will assist them in decreasing the likelihood of dance-related injury and ensuring that dancers receive optimum attention from the health care profession: (1 screening; (2 physical training; (3 nutrition and rest; (4 specialized dance health care; and (5 becoming acquainted with the nature of dance and dancers.

Gastrointestinal(GI) radiation-induced toxicity is a major complication and the transient or long-term problems, ranging from mild to very severe, arising in non-cancerous tissues resulting from radiation treatment to a tumor of pelvic origin, are actually called as pelvic radiation disease. The incidence of pelvic radiation disease changes according to the radiation technique, the length of follow up, the assessmentmethod, the type and stage of cancer and several other variables. Notably, even with the most recent radiation techniques, i.e., intensity-modulated radiotherapy, the incidence of radiation-induced GI side effects is overall reduced but still not negligible. In addition, radiation-induced GI side effects can develop even after several decades; therefore, the improvement of patient life expectancy will unavoidably increase the risk of developing radiation-induced complications. Once developed, the management of pelvic radiation disease may be challenging. Therefore, the prevention of radiation-induced toxicity represents a reasonable way to avoid a dramatic drop of the quality of life of these patients. In the current manuscript we provide an updated and practical review on the best available evidences in the field of the prevention of pelvic radiation disease.

  9. Relapse prevention for addictive behaviors

    Full Text Available Abstract The Relapse Prevention (RP model has been a mainstay of addictions theory and treatment since its introduction three decades ago. This paper provides an overview and update of RP for addictive behaviors with a focus on developments over the last decade (2000-2010. Major treatment outcome studies and meta-analyses are summarized, as are selected empirical findings relevant to the tenets of the RP model. Notable advances in RP in the last decade include the introduction of a reformulated cognitive-behavioral model of relapse, the application of advanced statistical methods to model relapse in large randomized trials, and the development of mindfulness-based relapse prevention. We also review the emergent literature on genetic correlates of relapse following pharmacological and behavioral treatments. The continued influence of RP is evidenced by its integration in most cognitive-behavioral substance use interventions. However, the tendency to subsume RP within other treatment modalities has posed a barrier to systematic evaluation of the RP model. Overall, RP remains an influential cognitive-behavioral framework that can inform both theoretical and clinical approaches to understanding and facilitating behavior change.

    Thermoplastic film added to proppants is effective and economical for preventing proppant flowback after an hydraulic fracturing treatment. Most other methods, such as resin-coated proppant and fiber, for controlling proppant flowback have drawbacks that added to treatment costs by requiring long downtime, costly additives, or frequent equipment replacement. Thermoplastic film does not react chemically with fracturing fluids. After the proppant is placed in the fracture, the film strips intertwine with the proppant grains or at higher temperatures, the strips become adhesive and shrink forming consolidated clusters that hold open the newly created fractures and prevent proppant from flowing back. The low cost of the film means that the strips can be used throughout the fracturing job or in selected stages. The strips are compatible with fracturing fluid chemistry, including breakers and crosslinkers, and can be used in wells with a wide range of bottom hole temperatures. The end result is a well that can be brought back on-line in a short time with little proppant flowback. This paper reviews the cost benefits and performance of these proppants.

  11. Public attitudes towards prevention of obesity.

    Claudia Sikorski

    Full Text Available OBJECTIVE: To investigate obesity prevention support in the German general public and to assess determinants of general prevention support as well as support of specific prevention measures. METHODS: This study was a cross-sectional analysis of a telephone based representative German study (3,003 subjects (52.8% women, mean age 51.9, s.d.  = 18.0, range 18-97 years. Likert scale-based questions on general prevention support and support of specific measures were used. Furthermore willingness to take part in preventive programs and willingness to pay were assessed. Stigmatizing attitudes were assessed with the Fat Phobia Scale (FPS. Causation of obesity was differentiated in three dimensions (internal, e.g. lack of exercise; external, e.g. social surroundings; and genetic factors. RESULTS: Obesity prevention was perceived as possible (98.2%, however, almost exclusively lifestyle changes were named. Participants with higher stigmatizing attitudes were less likely to believe obesity prevention is possible. The majority of participants would take part in preventive programs (59.6% and pay at least partially themselves (86.9%. Factor analysis revealed three dimensions of preventive measures: promoting healthy eating, restrictive and financial, governmental prevention efforts. In regard to these, promoting healthy eating was the most supported measure. Higher age, female gender and external causation were associated with higher support for all three dimensions of preventive measures. Only for governmental regulation, higher age was associated with lower support. CONCLUSION: Obesity prevention support in Germany is high. Structural prevention efforts are supported by the majority of the general public in Germany. The vast majority proclaims willingness to pay themselves for programs of weight gain prevention. This could be an indication of higher perceived self-responsibility in the German system but also for risen "fear of fat" in the population due

  16. Cardiovascular Prevention of Cognitive Decline

    Jean-Jacques Monsuez

    2011-01-01

    Full Text Available Midlife cardiovascular risk factors, including diabetes, hypertension, dyslipemia, and an unhealthy lifestyle, have been linked to subsequent incidence, delay of onset, and progression rate of Alzheimer disease and vascular dementia. Conversely, optimal treatment of cardiovascular risk factors prevents and slows down age-related cognitive disorders. The impact of antihypertensive therapy on cognitive outcome in patients with hypertension was assessed in large trials which demonstrated a reduction in progression of MRI white matter hyperintensities, in cognitive decline and in incidence of dementia. Large-scale database correlated statin use and reduction in the incidence of dementia, mainly in patients with documented atherosclerosis, but clinical trials failed to reach similar conclusions. Whether a multitargeted intervention would substantially improve protection, quality of life, and reduce medical cost expenditures in patients with lower risk profile has not been ascertained. This would require appropriately designed trials targeting large populations and focusing on cognitive decline as a primary outcome endpoint.

    Exposures and technologies in the workplace are changing due to a variety of factors, including newly developed technologies, mechanization and automation, and improvements in industrial hygiene primarily effected in many developed countries. In addition substitution and removal of carcinogenic constituents in the workplace and general environment are increasing in a number of instances, particularly in North America, Western Europe, and Japan, and they are being accompanied as well by remediation either by source reduction, recycling, or compliance to more stringent national and international regulations and standards. This overview highlights some of the strategies employed in the technological ages in cancer prevention and cites examples in source reduction, changes in formulation, product or process changes, recycling, and hazardous materials management

    We pilot-tested a street-level study of availability of physical resources to assess ethnic disparities in community capacity for cancer prevention in forty Brooklyn, NY, census tracts with high proportions of White, African American, or Jamaican immigrant populations. Interns with GIS maps made street-level inventories of food retailers, fast-food restaurants, and commercial exercise facilities. Availability was quantified as resources per capita or square mile. Median income-adjusted number of supermarkets, greengrocers and fast-food restaurants per square mile was significantly higher in Jamaican than in African American or White tracts. Bodegas per capita was greatest in African American tracts, with no significant differences among the population groups in availability of health food stores, or commercial exercise venues.

  19. Magnesium in Prevention and Therapy

    Directory of Open Access Journals (Sweden)

    Uwe Gröber

    2015-09-01

    Full Text Available Magnesium is the fourth most abundant mineral in the body. It has been recognized as a cofactor for more than 300 enzymatic reactions, where it is crucial for adenosine triphosphate (ATP metabolism. Magnesium is required for DNA and RNA synthesis, reproduction, and protein synthesis. Moreover, magnesium is essential for the regulation of muscular contraction, blood pressure, insulin metabolism, cardiac excitability, vasomotor tone, nerve transmission and neuromuscular conduction. Imbalances in magnesium status—primarily hypomagnesemia as it is seen more common than hypermagnesemia—might result in unwanted neuromuscular, cardiac or nervous disorders. Based on magnesium’s many functions within the human body, it plays an important role in prevention and treatment of many diseases. Low levels of magnesium have been associated with a number of chronic diseases, such as Alzheimer’s disease, insulin resistance and type-2 diabetes mellitus, hypertension, cardiovascular disease (e.g., stroke, migraine headaches, and attention deficit hyperactivity disorder (ADHD.

    Adolescents are unique for tobacco control. They are easy to become tobacco-addicted and more than 70 % of adult smokers start to smoke tobacco during adolescence. Therefore, they are good targets for sales campaign by tobacco industry to secure their profit by making a large reservoir of smokers. Tobacco industry's tactics are very ingenious. It conducts many kinds of hidden advertisement. It supports many activities of youth and nonprofit organizations. Therefore, our effort should also put targets on adolescents. Adolescence is a unique stage of development and it is important to know its characteristics for effective approach to prevent starting and to facilitate quitting smoking. It is important to make tobacco-free environment surrounding adolescents, such as school campuses and other public places.

  1. THE BASIS FOR SPEECH PREVENTION

    Directory of Open Access Journals (Sweden)

    Jordan JORDANOVSKI

    1997-06-01

    Full Text Available The speech is a tool for accurate communication of ideas. When we talk about speech prevention as a practical realization of the language, we are referring to the fact that it should be comprised of the elements of the criteria as viewed from the perspective of the standards. This criteria, in the broad sense of the word, presupposes an exact realization of the thought expressed between the speaker and the recipient.The absence of this criterion catches the eye through the practical realization of the language and brings forth consequences, often hidden very deeply in the human psyche. Their outer manifestation already represents a delayed reaction of the social environment. The foundation for overcoming and standardization of this phenomenon must be the anatomy-physiological patterns of the body, accomplished through methods in concordance with the nature of the body.

    2015-08-01

    The health and well-being of rapidly growing urban populations is a global health issue. Cities in the global north and south are faced with rising health inequities - or avoidable differences in health determinants and outcomes based on place, social status and ethnicity. This commentary suggests that focusing only on treatment interventions in cities is likely to fail because populations will be forced to go back into the urban living and working conditions that likely made them sick in the first place. City planning as preventive medicine includes taking a relational and systems approach to urban health, requiring health assessments for all urban policy making, promoting neighborhood health centers as engines of community economic development and gathering place-based health indicator data to track progress and adapt interventions over time as conditions change.

    2008-07-01

    While skin tears are common among the elderly in general, and residents of long-term care facilities in particular, there has been limited research into their treatment. Many facilities voluntarily track skin tears, and some states require facilities to report these events. Risk factors include age, xerosis (abnormal eye, skin, or mouth dryness), need for help in activities of daily living, presence of senile purpura, visual impairment, and poor nutrition. Plans to prevent skin tears that employ skin sleeves, padded side rails, gentle skin cleansers, moisturizing lotions, as well as staff education, can decrease by half the number of skin tears incurred in a long-term care facility. Although the treatment process seems simple, it is time consuming and can be painful for the patient. Residents with dementia or agitation often try to remove bulky dressings used to cover skin tears. Dressing changes may injure the fragile wound via skin stripping.

  6. Approaches to adolescent pregnancy prevention.

    1986-09-01

    The US has one of the highest teenage pregnancy rates in the industrialized world, over 1,000,000 a year. This can add to social problems including poverty, unemployment, family breakup, juvenile crime, school dropouts, and child abuse. In several studies various approaches have been developed and it is concluded that teens must not only be given the knowledge to avoid teen pregnancies, but the motivation to do so. Sex education is an important part of pregnancy prevention, but few programs go beyond the facts of reproduction and less than 14% of them are 40 hours long. Studies have shown mixed results as to the effect of education on teen pregnancy. There are many programs that have been developed by different communities, including computer programs and youth service agencies. Religious groups also play an important part in sex education and they have some distinct advantages in affecting teens' sexual values and activities. Education programs for teen's parents appear to be very important since studies show when sexuality is discussed at home, the teens begin activity later and use birth control more. Clinics have had difficulty recruiting and retaining teen patients and devote special attention to establishing a rapport with them. The school-based clinic is becoming increasingly popular and can provide birth control counseling, contraceptives, family planning clinic referral, examinations, pregnancy testing, and prenatal care. There success is due to confidentiality, convenience, and comprehensive service. However, since nearly all efforts on teen pregnancy prevention are directed at girls, 1/2 of those involved in teen pregnancies--males--are not participating in programs. This must change for longterm success of these programs and also the involvement of the community and media.

  7. Primary prevention of hepatocellular carcinoma.

    1995-01-01

    Hepatocellular carcinoma (HCC) is one of the major cancers in China. Accordingly, the mortality rates in 1990 (per 100,000) were 20.10 in certain cities and 24.32 in certain counties. More than 90% of HCC cases and 70% of controls were infected with the hepatitis B virus (HBV) (Odds Ratio (OR) = 10-50). In the same group of patients, 8-27% of those with HCC and 0-11% of the healthy controls were also infected with hepatitis C (HCV) (OR = 2.11-17.29). There appears to be some correlation between HBV markers and the OR. The government requires that 85% of infants be immunized with HBV vaccine. In 1992, there were 3 million infants inoculated with HB vaccines. Aflatoxins have been found as contaminants in food, particularly in corn, peanut oil, soya sauce and fermented soya beans. The intake of aflatoxin B1 (AFB1) by people of ten different villages correlated with HCC mortality rates (r = 0.55; P aflatoxins. These adducts are higher in hyperendemic HCC areas and cases. Most people have now changed their staple food and eat rice instead of corn. Six large epidemiological studies have confirmed that people who drink pond-ditch water experience higher HCC mortality rates than people who drink deep-well water. Recent research has found that the blue-green algal toxin microcystin (MCYST) was a contaminant of pond-ditch water. MCYST is a strong promoter of HCC and will induce severe intrahepatic haemorrhages and liver necrosis. More than 80% of people in Qidong County have already changed their sources of water from pond-ditches to deep wells. Therefore, a combined strategy of the prevention of hepatitis, control of crops and control of drinking water is advocated for the primary prevention of HCC in China.

    The field experiment within CAPS (Counterforce Applied to Prevent Spalling) was initiated to determine if the application of dry bentonite pellets is sufficient to suppress thermally-induced spalling in KBS-3 deposition holes. The experience gained from Aespoe Pillar Stability Experiment, conducted between 2002 and 2006, indicated that spalling could be controlled by the application of a small confining pressure in the deposition holes. The CAPS field experiment that included four pairs of boreholes with a diameter of approximately 0.5 m, was carried out as a series of demonstration experiments in the TASQ-tunnel. The first and second heating tests were performed in open holes, without any confining pressure on the borehole wall and the third and fourth heating tests with a confining pressure created by expanded clay pellets (LECA). The first heating test was initiated at the end of August 2008 and the final test was finished at the end of May 2009. The trials suggest that the small confining pressure offered by the LECA pellets was adequate to control spalling and prevent the formation of a highly conductive zone of fractured rock in the 500-mm-diameter holes. It is recommended that a full-scale test be carried out to assess if the findings are applicable to 1,750-mm-diameter deposition holes. Should the full scale tests support the findings from these initial trials, filling the gap between the bentonite blocks and rock wall with dry bentonite pellets will provide a viable engineered solution for controlling the effects of thermally induced spalling in the KBS-3 deposition holes

    Full Text Available It is easier to prevent a disease than to cure it. This postulate is a foundation stone of the contemporary medicine, furthermore its mission. The Chronic Kidney Diseases (CKD, amongst them the Chronic Pyelonephrites (CP and the mass kidney reduction  take an important  place in human pathologies in general, and in particular in renal ones. The Chronic Pyelonephrites  are chronic renal pathologies, which on one side are of various causes and on the other side are multi systemic. At the same time they tend, earlier or later, depending on their course, to bring the patient towards the Chronic Kidney Insufficiency  in stage of uremia, consequently in need of substitution therapies e.g. dialysis, peritoneum dialysis or transplant. It is worthy to emphasize that from the prevention and correct cure of CP make profit the patients, the family, the state and in the last analyses  the entire society, because in that way the budget expense destined for the fore going substitution cures, dialysis, peritoneum dialysis or transplant, is considerably  reduced. The same should be mentioned  in relation to the CP and the mass kidney reduction, speaking about our country, which are still at the first place as the very cause of Chronic Kidney  Insufficiencies (CRI, later on advancing toward uremia and terminal uremia along with its grave consequences. In general  the very foundation of the CP is on  the  infections of urinary roads, in particular on the complicated ones, among them it should be mentioned-congenital kidney anomalies, renal calculosis  so much present in our country, and pathologies of segment or vesical-ureteral reflux, and rarely the pathologies of prostate.

    2004-01-01

    Psychosocial factors refer to all organizational factors and interpersonal relationships in the workplace that may affect the health of the workers. Currently, two psychosocial risk models are universally recognized for producing solid scientific knowledge regarding the vital link between social or psychological phenomena at work and the development of several diseases, such as cardiovascular diseases or depression. The first is the "job demand-contro-support" model, which was defined by Karasek and to which the concept of social support has been added; the second is the "effort/reward imbalance" model defined by Siegrist. The public health perspective calls for theoretical models based on certain psychosocial attributes of the work environment for which there is empirical evidence of their pathogenic potential for exposed workers. Not only do these models reduce the complexity of the psychosocial reality of the work to components that are significant in terms of health risks, but they also facilitate the development and implementation of workplace interventions. Psychosocial risk intervention strategies currently implemented by companies are predominantly individual-oriented and aim chiefly at reducing the effects of stressful work situations by improving individual ability to adapt to the situation and manage stress. Like personal protection equipment for exposure to physical or chemical risks, these secondary prevention measures are commendable but insufficient, because they aim to reduce only the symptoms and not the cause of problems. Any intervention program for these risks should necessarily include a primary prevention component with a view to eliminating, or at least reducing, the psychosocial pathogenic agents in the workplace. Several authors have suggested that well-structured organizational approaches are most effective and should generate more important, longer-lasting effects than individual approaches. However, the evidence should be strengthened by

    Stereotype threat (ST) refers to a situation in which a member of a group fears that her or his performance will validate an existing negative performance stereotype, causing a decrease in performance. For example, reminding women of the stereotype "women are bad at math" causes them to perform more poorly on math questions from the SAT and GRE. Performance deficits can be of several types and be produced by several mechanisms. We show that ST prevents perceptual learning, defined in our task as an increasing rate of search for a target Chinese character in a display of such characters. Displays contained two or four characters and half of these contained a target. Search rate increased across a session of training for a control group of women, but not women under ST. Speeding of search is typically explained in terms of learned "popout" (automatic attraction of attention to a target). Did women under ST learn popout but fail to express it? Following training, the women were shown two colored squares and asked to choose the one with the greater color saturation. Superimposed on the squares were task-irrelevant Chinese characters. For women not trained under ST, the presence of a trained target on one square slowed responding, indicating that training had caused the learning of an attention response to targets. Women trained under ST showed no slowing, indicating that they had not learned such an attention response.

  1. [Preventive vaccinations for medical personnel].

    Vaccinations are among the most efficient and important preventive medical procedures. Modern vaccines are well tolerated. In Germany there are no longer laws for mandatory vaccinations, either for the general public or for medical personnel. Vaccinations are now merely "officially recommended" by the top health authorities on the basis of recommendations from the Standing Committee on Vaccinations (STIKO) of the Robert Koch Institute (RKI) according to § 20 para 3 of the Protection against Infection law (IfSG). The management of vaccine damage due to officially recommended vaccinations is guaranteed by the Federal States. Whereas vaccinations in childhood are generally considered to be a matter of course, the willingness to accept them decreases markedly with increasing age. In the medical sector vaccinations against, for example, hepatitis B are well accepted while other vaccinations against, for example, whooping cough or influenza are not considered to be so important. The fact that vaccinations, besides offering protection for the medical personnel, may also serve to protect the patients entrusted to medical care from nosocomial infections is often ignored.

    The best means of preventing crime is to make it difficult to commit. As the summer holidays begin, in everybody’s interest we advise the following precautions: 1. MONEY, VALUABLES & KEYS Never leave money or objects of value unattended in offices or changing rooms, even locked. Keys and spares must always be taken away or kept in a safe place. Supposedly “safe” hiding places such as drawers, even locked, metal boxes and flower pots, are well known to burglars and should be avoided. Change lock codes regularly. 2. DOORS & WINDOWS Offices, workshops and meeting-rooms, etc. should be locked when vacated. Care should also be taken that windows are properly shut, especially if they are easily accessible from the outside. 3. VANDALISM If you witness an act of vandalism of public or private property, please report all the facts and your observations immediately to the CERN Fire Brigade (74444). 4. REPORTING INCIDENTS Every misdemeanour solved increases the chances of others be...

  3. Menopause: Prevention and Health Promotion

    2009-01-01

    Full Text Available Taking into account that climacteric constitutes a physiological state in woman’s life, which covers a large stage of her life cycle, it is important that nursery professionals will develop an Action Plan, whose main objective will be health. Covering, then, this stage from a multidisciplinary and holistic field is going to contribute to both: the adoption of healthy life habits and the repercussions that symptoms and physiological processes associated with menopause have on women. Another objective for nurses there must be to provide all our knowledge in a detailed and focused on the individual needs that may come up way. That way, we lay the foundations for facing climacteric with the minimum deterioration of the quality of life and well being.This article is an analysis of the etiology of every one of the most prevalent menopause problems, the predisposing factors to suffer them or to make them get worse, and the habits that are going to prevent larger spill-over effects of those problems. Furthermore, a revision about how nutrition, exercise, toxic substances consumption, etc. have repercussions on musculoskeletal problems, vascular symptoms, urogenital problems, psychological alterations, and gynaecological and breast cancer is made.

  4. Preventing dance injuries: current perspectives.

    Russell, Jeffrey A

    2013-09-30

    Dancers are clearly athletes in the degree to which sophisticated physical capacities are required to perform at a high level. The standard complement of athletic attributes - muscular strength and endurance, anaerobic and aerobic energy utilization, speed, agility, coordination, motor control, and psychological readiness - all are essential to dance performance. In dance, as in any athletic activity, injuries are prevalent. This paper presents the research background of dance injuries, characteristics that distinguish dance and dancers from traditional sports and athletes, and research-based perspectives into how dance injuries can be reduced or prevented, including the factors of physical training, nutrition and rest, flooring, dancing en pointe, and specialized health care access for dancers. The review concludes by offering five essential components for those involved with caring for dancers that, when properly applied, will assist them in decreasing the likelihood of dance-related injury and ensuring that dancers receive optimum attention from the health care profession: (1) screening; (2) physical training; (3) nutrition and rest; (4) specialized dance health care; and (5) becoming acquainted with the nature of dance and dancers.

  5. Injury prevention and public health

    2010-06-01

    Full Text Available Injuries are one of the most under-recognized public health problems facing the world today. With more than 5 million deaths every year, violence and injuries account for 9% of global mortality, as many deaths as from HIV, Malaria and Tuberculosis combined. Eight of the 15 leading causes of death for people ages 15 to 29 years are injury-related: road traffic injuries, suicides, homicides, drowning, burns, war injuries, poisonings and falls. For every death due to war, there are three deaths due to homicide and five deaths due to suicide. However, most violence happens to people behind closed doors and results not in death, but often in years of physical and emotional suffering [1]. Injuries can be classified by intent: unintentional or intentional. Traffic injuries, fire-related injuries, falls, drowning, and poisonings are most often classified as unintentional injuries; injuries due to assault, selfinflicted violence such as suicide, and war are classified as intentional injuries, or violence. Worldwide, governments and public and private partners are increasingly aware of the strains that unintentional injuries and violence place on societies. In response they are strengthening data collection systems, improving services for victims and survivors, and increasing prevention efforts [1].

  6. Corrosion Preventive Compounds Lifetime Testing

    Science.gov (United States)

    Hale, Stephanie M.; Kammerer, Catherine C.; Copp, Tracy L.

    2007-01-01

    Lifetime Testing of Corrosion Preventive Compounds (CPCs) was performed to quantify performance in the various environments to which the Space Shuttle Orbiter is exposed during a flight cycle. Three CPCs are approved for use on the Orbiter: RD Calcium Grease, Dinitrol AV-30, and Braycote 601 EF. These CPCs have been rigorously tested to prove that they mitigate corrosion in typical environments, but little information is available on how they perform in the unique combination of the coastal environment at the launch pad, the vacuum of low-earth orbit, and the extreme heat of reentry. Currently, there is no lifetime or reapplication schedule established for these compounds that is based on this combination of environmental conditions. Aluminum 2024 coupons were coated with the three CPCs and exposed to conditions that simulate the environments to which the Orbiter is exposed. Uncoated Aluminum 2024 coupons were exposed to the environmental conditions as a control. Visual inspection and Electro- Impedance Spectroscopy (EIS) were performed on the samples in order to determine the effectiveness of the CPCs. The samples were processed through five mission life cycles or until the visual inspection revealed the initiation of corrosion and EIS indicated severe degradation of the coating.

    Mayer, Cora A; Neilson, Amy A

    2010-03-01

    This article is the second in a series providing a summary of prevention strategies and vaccination for infections that may be acquired by travellers. The series aims to provide practical strategies to assist general practitioners in giving travel advice, as a synthesis of multiple information sources which must otherwise be consulted. Poliomyelitis is a potentially fatal viral illness, which may cause acute flaccid paralysis and permanent central nervous system damage. Ongoing global efforts to eradicate poliomyelitis have been under way since 1988. Travellers are at risk of infection in countries with endemic wild poliomyelitis virus or imported cases, and can spread the infection to areas where poliomyelitis has been eradicated. While all adults should be immune to poliomyelitis, it is important that at-risk travellers are vaccinated appropriately. Vaccine options and regions currently reporting poliomyelitis are presented from a number of sources, which may facilitate the process of giving travel advice in a general practice setting, although it is also important to seek up-to-date epidemiological information.

    Lopez, E.P.; Modderman, W.E.; Montoya, M.G.

    1999-02-10

    As part of a pollution prevention program, a study was conducted at Sandia National Laboratories and at the Amarillo, ''Pantex Plant'' to identify a suitable replacement solvent(s) for cleaning hardware during routine maintenance operations. Current cleaning is performed using solvents (e.g. acetone, toluene, MEK, alcohols) that are classified as Resource Conservation and Recovery Act (RCW) materials. The Environmental Protection Agency (EPA) has assigned four characteristics as the criteria for determining whether a material is identified as hazardous under RCRA: Ignitability, Corrosivity, Reactivity and Toxicity. Within the DOE and DoD sector, these solvents are used with hand wipes to clean surfaces prior to O-ring replacement, to remove decals for new labeling, to clean painted surfaces prior to reconditioning, and for other general maintenance purposes. In some cases, low level radioactive contamination during cleaning necessitates that the RCIL4 solvent-containing wipes be classified as mixed waste. To avoid using RCRA materials, cleaning candidates were sought that had a flashpoint greater than 140 F, a pH between 2.5 and 12.5, and did not fail the reactivity and toxicity criteria. Three brominated cleaners, two hydrofluoroether azeotropes and two aliphatic hydrocarbon cleaner formulations were studied as potential replacements. Cleaning efficacy, materials compatibility, corrosion and accelerated aging studies were conducted and used to screen potential candidates. Hypersolve NPB (an n-propyl bromide based formulation) consistently ranked high in removing typical contaminants for weapons applications.

    Full Text Available Background: Robotic vehicles such as straddle carriers represent a popular form of cargo handling amongst container terminal operators.Objectives: The purpose of this industry-driven study is to model preventative maintenance (PM influences on the operational effectiveness of straddle carriers.Method: The study employs historical data consisting of 21 273 work orders covering a 27-month period. Two models are developed, both of which forecast influences of PM regimes for different types of carrier.Results: The findings of the study suggest that the reliability of the straddle fleet decreases with increased intervals of PM services. The study also finds that three factors – namely resources, number of new straddles, and the number of new lifting work centres – influence the performances of straddles.Conclusion: The authors argue that this collaborative research exercise makes a significant contribution to existing supply chain management literature, particularly in the area of operations efficiency. The study also serves as an avenue to enhance relevant management practice.

  10. OPTIMUM ORDERING POLICY FOR PREVENTIVE AGE REPLACEMENT

    Institute of Scientific and Technical Information of China (English)

    Young T.PARK; Jing SUN

    2009-01-01

    Most of the spare ordering policies treated up to now have assumed that preventive and corrective replacement costs are equal, which implies in essential that there is no significant need for preventive replacement. This paper presents an ordering policy for preventive age replacement with minimal repair. Introducing the replacement, repair, inventory holding and shortage costs, the expected cost rate is derived. A procedure to determine jointly the ordering time for a spare and the preventive replacement time for the operating unit so as to minimize the expected cost rate is proposed. To explain the ordering policy and the optimization procedure, a numerical example is also included.

    Quintero, J; Martin, M; Alcindor, P; Perez-Templado, J

    2016-01-01

    Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that begins at an early age and can be present until adulthood. Subjects with ADHD not only have symptoms such as inattention, impulsivity or hyperactivity but also have their social and emotional areas affected. In addition, they have an associated increased risk for presenting comorbilities with other psychiatric disorders, overshadowing the development. Considering ADHD as a evolutionary risk factor, prevention should be considered as a primary goal. Most preventive actions on ADHD have been focused on tertiary prevention. The present review aims to study the factors involved in the development of ADHD in order to form a prevention model beyond tertiary prevention. This research focuses on models of primary prevention (early detection of disease) and secondary prevention (to prevent or delay the disease), trying to incorporate them into daily practice. This study reviews risk factors that affect ADHD. Through actions aimed to pursue an early detection, development of the disorder could be improved, and by identifying population at risk, efforts could be concentrated on developing a true primary prevention (perinatal period and early childhood) that eventually could contribute to reduce the incidence of ADHD.

  15. Workplace Bullying Prevention: A Critical Discourse Analysis

    JOHNSON, Susan L.

    2016-01-01

    Aim To analyze the discourses of workplace bullying prevention of hospital nursing unit managers and in the official documents of the organizations where they worked. Background Workplace bullying can be a self-perpetuating problem in nursing units. As such, efforts to prevent this behavior may be more effective than efforts to stop the behavior. There is limited research on how healthcare organizations characterize their efforts to prevent workplace bullying. Design This was a qualitative study. Method Critical discourse analysis and Foucault’s writings on governmentality and discipline were used to analyze data from interviews with hospital nursing unit managers (n=15) and organizational documents (n=22). Data were collected in 2012. Findings The discourse of workplace bullying prevention centered around three themes: prevention of workplace bullying through managerial presence, normalizing behaviors and controlling behaviors. All three are individual level discourses of workplace bullying prevention. Conclusion Current research indicates that workplace bullying is a complex issue with antecedents at the individual, departmental and organizational level. However, the discourse of the participants in this study only focused on prevention of bullying by moulding the behaviors of individuals. The effective prevention of workplace bullying will require departmental and organizational initiatives. Leaders in all types of organizations can use the results of this study to examine their organizations’ discourses of workplace bullying prevention to determine where change is needed. PMID:26010268

  5. Achieving monospermy or preventing polyspermy?

    Directory of Open Access Journals (Sweden)

    Dale B

    2016-06-01

    Full Text Available Brian Dale Centre for Assisted Fertilization, Naples, Italy Abstract: Images of sea urchin oocytes with hundreds of spermatozoa attached to their surface have fascinated scientists for over a century and led to the idea that oocytes have evolved mechanisms to allow the penetration of one spermatozoon while repelling supernumerary spermatozoa. Popular texts have extrapolated this concept, to the mammals and amphibians, and in many cases to include all the Phyla. Here, it is argued that laboratory experiments, using sea urchin oocytes deprived of their extracellular coats and inseminated at high densities, are artifactual and that the experiments leading to the idea of a fast block to polyspermy are flawed. Under natural conditions, the number of spermatozoa at the site of fertilization is extremely low, compared with the numbers generated. The sperm:oocyte ratio is regulated first by dilution in externally fertilizing species and the female reproductive tract in those with internal fertilization, followed by a bottleneck created by the oocytes extracellular coats. In order to progress to the oocyte plasma membrane, the fertilizing spermatozoon must encounter and respond to a correct sequence of signals from the oocytes extracellular coats. Those that do not, are halted in their progression by defective signaling and fall to the wayside. Final success and entry is finely tuned by the spermatozoon anchoring to an actin-rich predetermined site on the plasma membrane. In this review, the variation in the form, function, and number of gametes produced across the animal kingdom and the many ways in which sperm–oocyte interactions are regulated to reduce numbers are discussed. Since in nature, final sperm:oocyte ratios approach unity it would appear that selective pressures have favored the achievement of monospermy, rather than the evolution of polyspermy preventing mechanisms. Keywords: monospermy, natural conditions, polyspermy, laboratory

    Bradshaw, Catherine P

    2015-01-01

    Bullying continues to be a concern in schools and communities across the United States and worldwide, yet there is uncertainty regarding the most effective approaches for preventing it and addressing its impacts on children and youth. This paper synthesizes findings from a series of studies and meta-analyses examining the efficacy of bullying prevention programs. This paper considers some methodological issues encountered when testing the efficacy and effectiveness of bullying prevention and intervention approaches. It also identifies several areas requiring additional research in order to increase the effectiveness of bullying prevention efforts in real-world settings. Drawing upon a public health perspective and findings from the field of prevention science, this paper aims to inform potential future directions for enhancing the adoption, high quality implementation, and dissemination of evidence-based bullying prevention programs. It is concluded that although bullying prevention programs can be effective in reducing bullying and victimization among school-aged youth, there is a great need for more work to increase the acceptability, fidelity, and sustainability of the existing programs in order to improve bullying-related outcomes for youth. The findings from this review are intended to inform both policy and public health practice related to bullying prevention.

  18. Stroke Prevention: Managing Modifiable Risk Factors

    Directory of Open Access Journals (Sweden)

    Silvia Di Legge

    2012-01-01

    Full Text Available Prevention plays a crucial role in counteracting morbidity and mortality related to ischemic stroke. It has been estimated that 50% of stroke are preventable through control of modifiable risk factors and lifestyle changes. Antihypertensive treatment is recommended for both prevention of recurrent stroke and other vascular events. The use of antiplatelets and statins has been shown to reduce the risk of recurrent stroke and other vascular events. Angiotensin-converting enzyme inhibitors (ACEIs and angiotensin II receptor blockers (ARBs are indicated in stroke prevention because they also promote vascular health. Effective secondary-prevention strategies for selected patients include carotid revascularization for high-grade carotid stenosis and vitamin K antagonist treatment for atrial fibrillation. The results of recent clinical trials investigating new anticoagulants (factor Xa inhibitors and direct thrombin inhibitors clearly indicate alternative strategies in stroke prevention for patients with atrial fibrillation. This paper describes the current landscape and developments in stroke prevention with special reference to medical treatment in secondary prevention of ischemic stroke.

    2013-01-01

    Prostate cancer is the most common malignancy in men in the United States. Surgery or radiation are sometimes unsatisfactory treatments because of the complications such as incontinence or erectile dysfunction. Selenium was found to be effective to prevent prostate cancer in the Nutritional Prevention of Cancer Trial (NPC), which motivated two other clinical trials: the Selenium and Vitamin E Cancer Prevention Trial (SELECT) and a Phase III trial of selenium to prevent prostate cancer in men with high-grade prostatic intraepithelial neoplasia. However, these two trials failed to confirm the results of the NPC trial and indicated that the selenium may not be preventive of prostate cancer. In this article we review the three clinical trials and discuss some different points which might be potential factors underlying variation in results obtained.

  8. Does prevention for Alzheimer's disease exist?

    Directory of Open Access Journals (Sweden)

    Sonia Maria Dozzi Brucki

    Full Text Available Abstract The prevention of Alzheimer's disease is a growing public health concern amidst an ageing population. Meanwhile, there is no effective or curative treatment available where prevention could greatly reduce health costs. This review was based on reports of potential preventive factors, including modifiable lifestyle factors, as well as preventive pharmacological strategies. Although the present review was not systematic, the reports selected from PubMed using "Alzheimer's disease" and "prevention" as key-words, allow us to affirm that pursuing a healthy lifestyle; physical, cognitive, leisure activities; good social engagement; a high consumption of fish, low consumption of dietary fat and moderate consumption of wine, and control of vascular risk factors appear to be potential factors for delaying dementia.

    Martínez González, C; Riaño Galán, I; Sánchez Jacob, M; González de Dios, J

    2014-12-01

    The growing capacity of medicine to generate more iatrogenic events than ever, and the risk of unsustainability of health systems have led to new prevention concept: quaternary prevention aimed at restraining medicalization. Quaternary prevention is essential in the phenomenon called disease mongering, which could be translated as commercialization of disease. Encouraging this sort of prevention and halting the consequences of disease mongering requires the development of all the institutional potential for prevention, as well as all the personal willingness for restraint; it involves separating us from the unnecessary auspices of industry, being critical of our work, not being maleficent, respecting the principle of justice as managers of the limited public resources and making ourselves feel responsible for the social cost resulting from medical decisions. From this point of view, this work analyses neonatal screening, developments in the area of neonatology and primary health care.

    The limited success of youth violence prevention interventions suggests that effective prevention needs to address causes at multiple levels of analysis and empower youth in developing and implementing prevention programs. In this article, we review published studies of youth violence prevention efforts that engage youth in developing or implementing violence prevention activities. The reviewed studies suggest the promise of youth empowerment strategies and the need for systematic outcome studies of empowerment programs. After reviewing empowerment theory applied to youth violence prevention programs, we present a case study of the Youth Empowerment Solutions (YES) for Peaceful Communities program. YES engages middle-school youth in an after-school and summer program that includes a culturally tailored character development curriculum and empowers the youth to plan and implement community improvement projects with assistance from adult neighborhood advocates. The case study focuses on outcome evaluation results and presents evidence of the YES program effects on community-level outcomes (eg, property improvements, violent crime incidents) and on individual-level outcomes (eg, conflict avoidance, victimization). The literature review and the case study suggest the promise of engaging and empowering youth to plan and implement youth violence prevention programs.

    2012-09-01

    Groundwater contamination prevention mapping is an important component of groundwater contamination geological survey and assessment work, which could provide the basis for making and implementing groundwater contamination prevention planning. A groundwater contamination prevention mapping system was constructed in view of the synthetic consideration on nature perspective derived from groundwater contamination sources and aquifer itself, social-economic perspective, policy perspective derived from outside. During the system construction process, analytic hierarchy process and relevant overlaying principles were used to couple groundwater contamination risk assessment, groundwater value as well as wellhead protection area zoning. Data processing and visualization of mapping results were achieved in the GIS environment. The research on groundwater contamination prevention mapping in Beijing Plain indicated that the final groundwater prevention map was in accordance with the actual conditions and well reflected the priorities of groundwater prevention, which could play a guidance role in designing and implementing further practical prevention and supervision measures. Besides, because of the dynamical properties of the system components, it was suggested to analyze the update frequency of the mapping.

  15. Strategies for the prevention of unsafe abortion.

    Science.gov (United States)

    Faúndes, Anibal

    2012-10-01

    Unsafe abortion is one of the main causes of maternal mortality and severe morbidity in countries with restrictive abortion laws. In 2007, the International Federation of Gynecology and Obstetrics (FIGO) created a Working Group on the Prevention of Unsafe Abortion and its Consequences (WGPUA). This led to a FIGO initiative with that aim which has the active participation of 43 FIGO member societies. The WGPUA has recommended that the plans of action of the countries participating in the initiative consider several levels of prevention shown to have the potential to successfully reduce unsafe abortions: (1) primary prevention of unintended pregnancy and induced abortion; (2) secondary prevention to ensure the safety of an abortion procedure that could not be avoided; (3) tertiary prevention of further complications of an unsafe abortion procedure that has taken place already, through high-quality postabortion care; and (4) quaternary prevention of repeated abortion procedures through postabortion family planning counseling and contraceptive services. This paper reviews these levels of prevention and the evidence that they can be effective.

  16. Preventive health measures in inflammatory bowel disease

    2016-01-01

    We aim to review the literature and provide guidance on preventive health measures in inflammatory bowel disease (IBD). Structured searches were performed in PubMed, MEDLINE, EMBASE, Web of Science and Cochrane Library from January 1976 to June 2016 using the following keywords: (inflammatory bowel disease OR Crohn’s disease OR ulcerative colitis) AND (health maintenance OR preventive health OR health promotion). Abstracts of the articles selected from each of these multiple searches were reviewed, and those meeting the inclusion criteria (that is, providing data regarding preventive health or health maintenance in IBD patients) were recorded. Reference lists from the selected articles were manually reviewed to identify further relevant studies. Patients with IBD are at increased risk of developing adverse events related to the disease course, therapeutic interventions, or non-adherence to medication. Recent studies have suggested that IBD patients do not receive preventive services with the same thoroughness as patients with other chronic diseases. Preventive health measures can avert morbidity and improve the quality of life of patients with IBD. Gastroenterologists and primary care physicians (PCPs) should have an up to date working knowledge of preventive health measures for IBD patients. A holistic approach and better communication between gastroenterologists and PCPs with explicit clarification of roles will prevent duplication of services and streamline care. PMID:27678347

  17. Optimization of preventive health care facility locations

    Directory of Open Access Journals (Sweden)

    McGregor S

    2010-03-01

    Full Text Available Abstract Background Preventive health care programs can save lives and contribute to a better quality of life by diagnosing serious medical conditions early. The Preventive Health Care Facility Location (PHCFL problem is to identify optimal locations for preventive health care facilities so as to maximize participation. When identifying locations for preventive health care facilities, we need to consider the characteristics of the preventive health care services. First, people should have more flexibility to select service locations. Second, each preventive health care facility needs to have a minimum number of clients in order to retain accreditation. Results This paper presents a new methodology for solving the PHCFL problem. In order to capture the characteristics of preventive health care services, we define a new accessibility measurement that combines the two-step floating catchment area method, distance factor, and the Huff-based competitive model. We assume that the accessibility of preventive health care services is a major determinant for participation in the service. Based on the new accessibility measurement, the PHCFL problem is formalized as a bi-objective model based on efficiency and coverage. The bi-objective model is solved using the Interchange algorithm. In order to accelerate the solving process, we implement the Interchange algorithm by building two new data structures, which captures the spatial structure of the PHCFL problem. In addition, in order to measure the spatial barrier between clients and preventive health care facilities accurately and dynamically, this paper estimates travelling distance and travelling time by calling the Google Maps Application Programming Interface (API. Conclusions Experiments based on a real application for the Alberta breast cancer screening program show that our work can increase the accessibility of breast cancer screening services in the province.

    Science.gov (United States)

    Wofford, Linda G

    2008-02-01

    This systematic review identified the current state of the evidence related to the prevention of obesity in young children. The results indicate five areas of emphasis in the literature: prevalence of the problem; prevention as the best option; preschool population as the target; crucial parental involvement; and numerous guidelines. Because the gap between clear articulation of the problem as well as population and the best strategies to impact the prevention of the problem is evident, health care practitioners must be involved in well-constructed implementation and evaluation studies that build on the limited base of current evidence.

  19. Suicide Prevention Strategies for Improving Population Health.

    Wilcox, Holly C; Wyman, Peter A

    2016-04-01

    Suicide is a public health problem that accounts for more than 1 million deaths annually worldwide. This article addresses evidence-based and promising youth suicide prevention approaches at the primary, secondary, and tertiary levels. Coordinated, developmentally timed, evidence-based suicide prevention approaches at all intervention levels are likely to reduce youth suicide. For most youth who die by suicide, there are opportunities for intervention before imminent risk develops. Current research in suicide prevention points to the value of investing in "upstream" universal interventions that build skills and resilience as well as policies that enable access to care and protection from lethal means.

    Workplace bullying is a significant occupational health problem worldwide. Nurses are vulnerable to workplace bullying. During interactions with staff nurses, occupational health nurses have crucial opportunities to identify victims of workplace bullying and provide effective techniques for preventing and managing workplace bullying behaviors. The purpose of this systematic review was to identify best practices for preventing and managing workplace bullying among staff nurses. The best method found to control and stop workplace bullying involves cognitive rehearsal of responses to common bullying behaviors. Translation of the 3-hour workplace bullying prevention and management program is discussed.
