Encapsulation of Spirulina protein hydrolysates in liposomes: Impact on antioxidant activity and gastrointestinal behavior.

A Spirulina hydrolysate was encapsulated within anionic liposomes composed of soybean lecithin and γ-oryzanol at an encapsulation efficiency of 90 %. A combination of 10 mg/mL hydrolysate and 1.3 mg/mL γ-oryzanol exhibited a significant synergism in inhibition of the formation of thiobarbituric acid-reactive substances (TBARS) and provided good protection of the liposomes against oxidation. The particle size of the liposomes increased significantly in the presence of the hydrolysate. Chitosomes were formed by coating the anionic liposomes with cationic chitosan. The antioxidant activity of the hydrolysate-loaded liposomes and chitosomes and free hydrolysate decreased under the highly acidic conditions in the stomach with the reduction in activity being greatest for the free hydrolysate. However, after exposure to small intestine conditions, the antioxidant activity of all formulations increased significantly (p < 0.05). This study highlights the potential of non-coated and coated liposomes to increase the stability and bioactivity of bioactive protein hydrolysates.

Increased expression of androgen receptor and PSA genes in LNCaP (prostate cancer) cell line due to high concentrations of EGCG, an active ingredient in green tea.

OBJECTIVES: Androgen receptor (AR) play a key role in the onset and progression of prostate cancer. Epigallocatechin-3-gallate (EGCG) is a polyphenolic compound and the active ingredient in green tea, which is involved in modulating gene expression through epigenetic alterations. Previous studies have shown that EGCG at low concentrations reduces the expression of AR and prostate-specific antigen (PSA) in the LNCaP cell line of prostate cancer. In this study, the effect of higher EGCG concentrations on AR and PSA expression in LNCaP prostate cancer cell line was investigated. METHODS: In this study, LNCaP prostate cancer cell line was used and after MTT test, concentrations of 40, 60 and 80 µg/mL EGCG were used for treatment. Then, the expression of AR and PSA genes was evaluated by RT-PCR. AR protein expression was also assessed by Western blotting. RESULTS: The present study showed that treatment of LNCaPs cells by EGCG reduces cell proliferation. The IC50 value was 42.7 µg/mL under experimental conditions. It was also observed that EGCG at concentrations of 40 and 80 µg/mL increased the expression of AR and PSA (p<0.05). CONCLUSIONS: The present study showed that the effect of EGCG on AR expression was different at different concentrations, so that unlike previous studies, higher concentrations of EGCG (80 and 40 µg/mL) increased AR and PSA expression. It seems that due to the toxic effects of EGCG in high concentrations on cancer cells and the possibility of its effect on normal cells, more caution should be exercised in its use.

Anti-Inflammatory Activity of Ferula assafoetida Oleo-Gum-Resin (Asafoetida) against TNF-α-Stimulated Human Umbilical Vein Endothelial Cells (HUVECs).

Inflammation is the body's biological reaction to endogenous and exogenous stimuli. Recent studies have demonstrated several anti-inflammatory properties of Ferula species. In this paper, we decided to study the anti-inflammatory effect of ethanolic extract of Ferula assafoetida oleo-gum-resin (asafoetida) against TNF-α-stimulated human umbilical vein endothelial cells (HUVECs). HUVECs were cultured in a flat-bottom plate and then treated with ethanolic extract of asafoetida (EEA, 0-500 µg/ml) and TNF-α (0-100 ng/ml) for 24 h. We used the MTT test to assess cell survival. In addition, the LC-MS analysis was performed to determine the active substances. HUVECs were pretreated with EEA and then induced by TNF-α. Intracellular reactive oxygen species (ROS) and adhesion of peripheral blood mononuclear cells (PBMCs) to HUVECs were evaluated with DCFH-DA and CFSE fluorescent probes, respectively. Gene expression of intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), and E-selectin and surface expression of ICAM-1 protein were measured using real-time PCR and flow cytometry methods, respectively. While TNF-α significantly increased intracellular ROS formation and PBMC adhesion to TNF-α-induced HUVECs, the pretreatment of HUVECs with EEA (125 and 250 µg/ml) significantly reduced the parameters. In addition, EEA pretreatment decreased TNF-α-induced mRNA expression of VCAM-1 and surface protein expression of ICAM-1 in the target cells. Taken together, the results indicated that EEA prevented ROS generation, triggered by TNF-α, and inhibited the expression of VCAM-1 and ICAM-1, leading to reduced PBMC adhesion. These findings suggest that EEA can probably have anti-inflammatory properties.

Effects of social hierarchy on innate fear­induced panic responses.

Studies have previously demonstrated a relationship between social status and anxiety disorders such as panic disorder. Repeated episodes of panic attacks do not occur in combination with an actual fear stimulus or stressor. However, social ranking modulates the perception of the social signals of a threat or stressor. The hypothalamic nuclei are well­known for their role in the elaboration of fear­induced reactions. The dorsomedial hypothalamus (DMH) and the ventromedial hypothalamic (VMH) nuclei are hypothalamic subnuclei involved in the processing of threatening stimuli­evoked aversive response and innate fear development. These structures are also located in the medial amygdala­hypothalamus­brainstem circuit that modulates innate fear­induced defensive behaviors. This work aimed to investigate the relationship between social hierarchy and innate fear­induced panic­like responses in male rats. In our study, the dominance tube test was used to determine the social hierarchy. Then, DMH/VMH nuclei were unilaterally implanted with a guide cannula. After intra­DMH/VMH injection of bicuculline (GABAA receptor antagonist), both innate fear induction and differences in dominant/subordinate rats were evaluated by the open field test. Intra­DMH/VMH bicuculline increased the frequency of defensive immobility, forward escape movements, and crossing behaviors, as well as the duration of defensive immobility and forward escape movements in dominant rats. Subordinate rats showed a higher frequency of defensive attention, defensive immobility, and crossing than dominant rats. Additionally, dominant rats demonstrated a lower duration of defensive attention and defensive immobility than subordinate rats. Dominant rats seemed to adopt a form of innate­fear characterized by increased proactivity with the environment. In contrast, subordinate rats exhibited a reactive form of innate­fear characterized by passivity and freezing.

Electrospun nanofiber based on Ethyl cellulose/Soy protein isolated integrated with bitter orange peel extract for antimicrobial and antioxidant active food packaging.

The present work was aimed to produce a novel bioactive nanofiber (NFs) based on Ethyl cellulose (EC), Soy protein isolated (SPI), and containing Bitter orange peel extract (BOPE) by electrospinning technology. The EC/SPI NFs were formulated with different weight ratios of 1:1, 2:1, and 1:2 denoted as ES11, ES21, and ES12, respectively, and investigated by several analyses. Based on the obtained results, the maximum hydrogen interactions between these two polymers, ES11 NFs offered a uniform morphology without bead with the diameter of 185.33 nm as a result of the compatibility of the polymer solutions of EC and SPI. Moreover, appropriate thermal stability was presented along with more porosity (78%), maximum water vapor transmission rate (657 g/m2.24h), good tensile stress (6.12 MPa), and acceptable water contact angel (82.3°). Therefore, ES11 NFs were selected as the optimal sample for incorporation of the BOPE as the antibacterial and antioxidant agent. According to the antioxidant activity test, the highest concentration (20% wt) of this extract increased the antioxidant activity of NF around 64.7% and also inhibited the growth of pathogenic bacteria (S. areus, and E. coli). Therefore, the ES11 electrospun NFs containing 20% BOPE can be a beneficial system to increase the safety and quality of foods.

Protective effect of piperine in ischemia-reperfusion induced acute kidney injury through inhibition of inflammation and oxidative stress.

BACKGROUND AND AIM: Renal ischemia-reperfusion is associated with inflammation and oxidative stress. As a major compound in black pepper, piperine has anti-inflammatory and anti-oxidative properties. In present study, the protective effects of oral administration of piperine in renal ischemia-reperfusion (IR) induced acute kidney injuries (AKI) were investigated. EXPERIMENTAL PROCEDURE: Male Wistar rats received piperine (10 or 20 mg/kg.bw) or vehicle for 10 days. The artery and vein of both kidneys were then clamped for 30 min, followed by a 24-h reperfusion period. Concentrations of creatinine and urea-nitrogen in descending aorta blood were measured, and malondialdehyde (MDA) and ferric reducing/antioxidant power (FRAP) levels were measured in kidney tissue to evaluate the oxidative stress. Inflammation was evaluated by measuring the TNF-α and ICAM-1 mRNA expression levels in renal cortical tissue using Real Time PCR method and counting leukocytes infiltration to interstitium. Further measured were tissue damages in H & E stained sections. RESULTS: Renal IR reduced FRAP, while increasing the plasma concentrations of creatinine and urea-nitrogen, tissue MDA level, TNF-α and ICAM-1 mRNA expressions, leukocyte infiltration and histopathologic injuries. Piperine administration significantly reduced the plasma concentrations of creatinine and urea-nitrogen, expression of pro-inflammatory factors, oxidative stress and renal histopathologic injuries. It is to be noted that 20 mg/kg dose was more effective. CONCLUSION: Our results suggest piperine protects the kidney against ischemia-reperfusion induced acute kidney injuries by its anti-inflammatory and anti-oxidative properties.

Low-level laser irradiation potentiates anticancer activity of p-coumaric acid against human malignant melanoma cells.

p-Coumaric acid (PCA) is a kind of phenolic compound, and as one of the cinnamic acid derivatives, it has many biological functions such as antioxidants, anti-inflammatory, antiplatelet, and anticancer activity. Low-level laser irradiation has received increasing interest in the fields of tissue regeneration and wound healing. In this study, the effect of low-level laser irradiation on human fibroblast cells (human dermal fibroblast) and human melanoma cancer cells (A375 and SK-MEL-37) treated with PCA was investigated. The human dermal fibroblast, A375, and SK-MEL-37 cells were exposed to low-level laser at 660-nm wavelength with 3 J/cm for 90 s, and then the cells were treated with different concentrations of PCA (0-1000 µg/ml for 24 h), separately. In another experiment, first the cells were treated by PCA and then irradiated with low-level laser as described before. The effect of various irradiation energy (1-6 J/cm) on the melanoma cells, which were then treated by PCA, was studied. The cell viability using MTT assay and lactate dehydrogenase assay was determined. Morphological changes owing to apoptosis induction by irradiation and PCA were detected by fluorescence microscopy using acridine orange/ethidium bromide double staining. The results showed that pretreatment with low-level laser irradiation and then PCA reduced the survival and growth of melanoma cells more than the early treatment with PCA and then low-level laser irradiation. Lactate dehydrogenase activity was reduced significantly by preirradiation and then PCA treatment in comparison with the dark group in melanoma cells. The cell cytotoxicity at different irradiation energy and then IC50 concentration of PCA was increased up to 3 J/cm and then decreased following increasing irradiation energy. The morphology study with light microscopy and apoptotic assay using acridine orange/ethidium bromide dual staining confirmed the MTT results. This study showed that low-level laser irradiation alone is not able to kill human normal fibroblast and human melanoma cancer cells. Preirradiation followed by treatment with PCA did not change the cell viability in human fibroblast significantly but reduced the cell viability in melanoma cells presumably through the apoptosis pathway.

Antimicrobial Activity of Nanostructured Lipid Carriers Loaded Punica granatum Seed Oil against Staphylococcus epidermidis.

BACKGROUND: Nanostructured lipid carriers (NLCs), due to their impressive benefits, have recently been considered in different areas. Besides, NLC loaded with essential oils is attractive for finding more effective antimicrobial products, especially against common bacteria such as Staphylococcus epidermidis (S. epidermidis). OBJECTIVE: This study aims to prepare and characterize NLCs encapsulated with Punica granatum (P. granatum) seed oil (PGS oil-loaded NLCs) and examine the antimicrobial effect of this combination against S. epidermidis. METHODS: PGS oil-loaded NLCs were prepared using a hot melt homogenization method. Later, they were characterized by determining particle size distribution (particle size analyzer), morphology (scanning electron microscopy (SEM)), and zeta potential (surface charge of NLCs). Minimum inhibitory concentrations (MIC) of PGS oil-loaded NLCs were assessed and compared with seed oil emulsion of P. granatum against S. epidermidis. RESULTS: PGS oil-loaded NLCs were spherical shaped nanoparticles, with a mean size of 102.10 nm and narrow size distribution (PDI = 0.26). The antibacterial assay showed PGS oil-loaded NLCs to have a higher in vitro antimicrobial activity than seed oil emulsion of P. granatum. CONCLUSION: To conclude, NLCs may be a favorable carrier to develop new antimicrobial agents. Lay Summary: The lipid nanoparticles such as nanostructured lipid carriers (NLCs) appeared as products first on the cosmetic market. Their advantages help them to be used in different healthcare and cosmetic products. With regard to previous studies, Punica granatum (P. granatum) extract shows antimicrobial and antioxidant properties that could be a valuable natural source against the wide ranges of bacteria. Then, P. granatum seed oil (PGS oil-loaded NLCs) prepared in this study can be used in dental and skin-related materials as a new natural antimicrobial product.

Prevalence and determinant factors of anemia in children aged 6-12 months after starting an iron supplement in the east of Iran.

OBJECTIVE: Anemia in infants is a common problem, with regular iron supplementation the suggested policy for prevention and control of anemia. The aim of this study was to determine the prevalence and the determining factors of anemia as well as the benefits of regular iron supplementation in 6- to 12-month-old children. DESIGN/SETTING/SUBJECTS: In this cross-sectional study, 897 children aged from 6 to 12 months cared for at the Tabas Health Centers, affiliated with Birjand University of Medical Sciences, South Khorasan, Iran, were enrolled in the study. Demographic and anthropometric data as well as the level of hemoglobin were collected through interviews and laboratory tests, respectively. Data analysis was performed using SPSS-22 and stata-13. Chi2, polychromic PCA, and logistic regression were used. The statistical significance level was 0.05. RESULT: The prevalence of anemia, according to the WHO criterion for hemoglobin, was 36.8% (95% CI, 33.6-40.0). Its prevalence showed a decreasing trend as age and duration of iron supplement increased. Each 1-month increase in infant age was associated with a decreased risk of anemia [OR=0.88 (95% CI, 0.80-0.98)]. Anemia was not significantly different between genders. Individuals in the highest category for parity (≥3) were at a 2.3-fold greater risk of anemia compared with the lowest category [OR=2.35 (95% CI, 1.43-3.84)]. In contrast, individuals in the highest category for maternal age (>35 years) had a 62% lower risk of anemia compared with the reference category (<25 years) [OR=0.38 (95% CI, 0.20-0.72)]. CONCLUSION: Implementation of an iron supplementation plan in Iran has decreased anemia among 6- to 12-month-old children.

A Review of Herbal Remedies for Multiple Sclerosis-Like Disorders in Traditional Persian Medicine (TPM).

BACKGROUND: Among various neurological disorders, multiple sclerosis (MS) is an expanding global immune- related inflammatory disease with complex etiologies. There is increasing demand for the use and administration of natural medicaments for this disorder. Traditional Persian Medicine (TPM) is a school of medicine and a medicinal plants-based resource for clinical studies put forward by Persian scholars. OBJECTIVE: This paper aims to gather and study the effectiveness of all medicinal plants from the most popular Persian pharmacopeias. Five main Persian pharmacopeias from the 9th to the 18th century A.D. have been studied to identify the remedial plants for this disorder. Moreover, PubMed, and Scopus databases have been checked to derive relevant activities for these plants. Khaddar (numbness), Esterkha (Palsy) and Falej (quadriplegia) are traditional definitions; these are clinically close to what is known as MS in today's medicine. CONCLUSION: In all, 118 medicinal plants, related to 65 families, have been authenticated out of 157 chosen medicaments. Apiaceae is the most frequent family (13 reports). Fruits and roots of plants have been the most reported botanical parts (34 and 32 items). The employed routes of administration are topical, oral, or a combination of the two (27, 57, and 34 sequentially). Fifteen medicines have been reported for Khaddar, Esterkha, and Falej simultaneously. Antioxidant activities, immunomodulatory, and anti-inflammatory properties of medicines are known as some main mechanisms to manage MS. These functions are possessed by 81%, 36%, and 48% of the studied plants, respectively. Hence, conducting adducible clinical trials and highly approved experimental tests on animals may lead to novel drugs with lesser undesirable and much more therapeutic effects on controlling MS.

The Effect of Aqueous Extract of Cinnamon on the Metabolome of Plasmodium falciparum Using (1)HNMR Spectroscopy.

Malaria is responsible for estimated 584,000 deaths in 2013. Researchers are working on new drugs and medicinal herbs due to drug resistance that is a major problem facing them; the search is on for new medicinal herbs. Cinnamon is the bark of a tree with reported antiparasitic effects. Metabonomics is the simultaneous study of all the metabolites in biological fluids, cells, and tissues detected by high throughput technology. It was decided to determine the mechanism of the effect of aqueous extract of cinnamon on the metabolome of Plasmodium falciparum in vitro using (1)HNMR spectroscopy. Prepared aqueous extract of cinnamon was added to a culture of Plasmodium falciparum 3D7 and its 50% inhibitory concentration determined, and, after collection, their metabolites were extracted and (1)HNMR spectroscopy by NOESY method was done. The spectra were analyzed by chemometric methods. The differentiating metabolites were identified using Human Metabolome Database and the metabolic cycles identified by Metaboanalyst. 50% inhibitory concentration of cinnamon on Plasmodium falciparum was 1.25 mg/mL with p < 0.001. The metabolites were identified as succinic acid, glutathione, L-aspartic acid, beta-alanine, and 2-methylbutyryl glycine. The main metabolic cycles detected were alanine and aspartame and glutamate pathway and pantothenate and coenzyme A biosynthesis and lysine biosynthesis and glutathione metabolism, which are all important as drug targets.

Effect of Topical Application of Nigella Sativa Oil and Oral Acetaminophen on Pain in Elderly with Knee Osteoarthritis: A Crossover Clinical Trial.

BACKGROUND: Limited evidence supports Nigella sativa's role as an effective complementary and alternative medicine and the anti-inflammatory effects of Nigella sativa on patients with allergic rhinitis. OBJECTIVE: The aim of this study was to investigate the effect of topical application of Nigella sativa oil and oral acetaminophen on pain in the elderly with knee osteoarthritis residing in a parents' home in Sabzevar. METHODS: This study is done as a crossover clinical trial. After obtaining written consent of elderly patients with osteoarthritis of the knee, they were randomly divided into two groups. In step 1, in group 1, 1 cc of Nigella sativa oil was applied on the knee joint every 8 hours for 3 weeks; for the second group, every 8 hours for 3 weeks, patients were given 1 tablet of 325 mg acetaminophen. After a period of 1 month without medication to wash out each group, in step 2, each treatment group received the drug interaction in the same way as above. Pain was determined using a visual scale (VAS) before and after the first and second stages. Treatment response was defined as a decrease in pain scores over 1.5. Data analysis was performed with an R software mixed model. RESULTS: This study was done on 40 elderly patients: 18 (45%) men and 22 (55%) women. Their mean year and weight were 75.66±8.9 years and 69.67±14.33 kg, respectively. Study results showed that topical application of Nigella sativa oil and oral acetaminophen reduced pain in elderly with knee osteoarthritis; after using Nigella sativa oil, the reduction of pain was higher (p=0.01). CONCLUSION: The results of this study showed that topical application of Nigella sativa oil was effective in reducing pain in patients with knee osteoarthritis; therefore, it is recommended as a safe supplement for these elderly. TRIAL REGISTRATION: The trial was registered at TCTR (http://www.clinicaltrials.in.th/) with the ID: TCTR20160125003. FUNDING: This study was approved and supported by the Sabzevar University of Medical Sciences.

A randomized, double blinded, placebo-controlled clinical trial of silymarin in ulcerative colitis.

OBJECTIVE: To evaluate the clinical efficacy of silymarin in ulcerative colitis (UC) patients. METHODS: A randomized double blinded placebo-controlled clinical trial was conducted in 80 UC patients whose disease had been documented and were in remission state between September 2009 and October 2010. Patients were assigned to silymarin group (42 cases) and placebo group (38 cases) using a random number table. Either silymarin (140 mg) or placebo (lactose mono-hydrate, corn starch magnesium stearate) tablets were given once daily for 6 months along with their standard therapy. The efficacies were assessed by disease activity index (DAI), frequency difference of the disease flare-up, and paraclinical data. RESULTS: Ten patients (4 in the silymarin group due to nausea and 6 in the placebo group due to disease flare-up and abdominal pain) discontinued the study. An improvement in hemoglobin level (11.8±1.6 g/dL vs. 13.4±1.2 g/dL,P<0.05) and erythrocyte sedimentation rate (23.7±11.5 mm/h vs.10.8±3.2 mm/h,P<0.05) was observed in the silymarin group but not in the placebo group. DAI significantly decreased in the silymarin group and reached from 11.3±3.5 to 10.7±2.8 (P<0.05). Thirty-five out of 38 patients in the silymarin group were in complete remission with no flare-up after 6 months as compared to 21 out of 32 patients in the placebo group (P=0.5000). CONCLUSION: Silymarin as a natural supplement may be used in UC patients to maintain remission.

Enhancing the properties of beam forming bolus in hyperthermia: numerical simulation and empirical verification.

In this paper we present a simulation study of the induced specific absorption rate (SAR) within the phantom produced by radiofrequency radiation from a 8 MHz capacitive applicator. The main focus of the current study is on demonstrating the beam shaping properties of the bolus system as well as its effect on controlling the therapeutic area. Different electrical conductivities and geometries of the bolus were considered in the simulation of induced SAR distributions in a muscle-equivalent model with uniform dielectric properties. To validate the presented model, we carried out a comparison between the SAR simulation results and the temperature measurements in an agar split-phantom and an excellent agreement was observed.

The effects of wet cupping on serum high-sensitivity C-reactive protein and heat shock protein 27 antibody titers in patients with metabolic syndrome.

INTRODUCTION: It has previously been reported that increased level of serum heat shock proteins (Hsps) antibody in patients with metabolic syndrome. It is possible that the expression of Hsp and inflammatory markers can be affected by cupping and traditional Chinese medicine. There is a little data investigating the effects of cupping on markers of inflammation and Hsp proteins, hence, the objective of this study was evaluation of the effects of wet cupping on serum high-sensitivity C-reactive protein (hs-CRP) and Hsp27 antibody titers in patients with metabolic syndrome. SUBJECTS AND METHODS: Serum Hs-CRP and Hsp27 antibody titers were assessed in samples from 126 patients with metabolic syndrome (18-65 years of age) at baseline, and after 6 and 12 weeks after treatment. One hundred and twenty-six patients were randomly divided into the experimental group treated with wet cupping combined with dietary advice, and the control group treated with dietary advice alone using a random number table. Eight patients in case group and five subjects in control groups were excluded from the study. Data were analyzed using SPSS 15.0 software and a repeated measure ANCOVA. RESULTS: Serum hs-CRP titers did not change significantly between groups (p>0.05) and times (p=0.27). The same result was found for Hsp27 titers (p>0.05). CONCLUSION: Wet-cupping on the interscapular region has no effect on serum hs-CRP and Hsp27 patients with metabolic syndrome.

Effects of auricular acupuncture on anthropometric, lipid profile, inflammatory, and immunologic markers: a randomized controlled trial study.

OBJECTIVES: A randomized controlled clinical trial was performed to examine the effectiveness of auricular acupuncture on body weight loss and its impact on lipid profile, and immunologic and inflammatory markers in obese subjects. METHODS: Participants (n=204) were randomized to therapeutic acupuncture and control groups. Subjects received authentic (cases) or sham (controls) acupuncture for 6 weeks (first period) in combination with a low-calorie diet. In the next 6 weeks (second period), the low-calorie diet was used on its own. Subjects were assessed at the beginning and 6 and 12 weeks later. In addition to anthropometric and lipid parameters, serum anti-heat shock protein (Hsp)-27, 60, 65, 70 and high sensitive C-reactive protein (hs-CRP) levels were assessed. RESULTS: In the first period, anthropometric parameters and hs-CRP changed significantly in both groups, while significant changes in anti-Hsp antibodies were only observed in case subjects. In the second period, which shows the sustainable effects of acupuncture, changes in anthropometric parameters were more prominent in controls, while significant reductions in the group receiving authentic acupuncture were maintained for anti-Hsp antibodies. A comparison between the first and second period in both groups showed that the changes for most of the parameters were more significant in the first period. Comparison between cases and controls showed that authentic acupuncture was more effective in reducing the levels of anthropometric factors and anti-Hsp antibodies but not hs-CRP. CONCLUSIONS: Auricular acupuncture in combination with diet restriction was effective for weight loss and dyslipidemia. Moreover, it was found that it has immunomodulatory but not anti-inflammatory effects on the immune system by regulation of the levels of anti-Hsp antibodies.

The effects of body acupuncture on obesity: anthropometric parameters, lipid profile, and inflammatory and immunologic markers.

A randomized controlled clinical trial in 196 obese subjects was performed to examine the effectiveness of body acupuncture on body weight loss, lipid profile and immunogenic and inflammatory markers. Subjects received authentic (cases) or sham (controls) acupuncture for 6 weeks in combination with a low-calorie diet. In the following 6 weeks, they received the low-calorie diet alone. Subjects were assessed at the beginning, 6 and 12 weeks later. Heat shock protein (Hsps)-27, 60, 65, 70 antibody titers and high sensitivity C-reactive protein (hs-CRP) levels were also assessed. A significant reduction in measures of adiposity and improvement in lipid profile were observed in both groups, but the levels of anti-Hsp-antibodies decreased in cases only. A reduction in anthropometric and lipid profile in cases were sustained in the second period, however, only changes in lipid profile were observed in the control group. Anti-Hsp-antibodies and hs-CRP levels continued to be reduced in cases but in controls only the reduction in hs-CRP remained. Changes in anthropometric parameters, lipid profile, and anti-Hsp-antibodies were more evident in cases. Body acupuncture in combination with diet restriction was effective in enhancing weight loss and improving dyslipidemia.

The effects of wet cupping on coronary risk factors in patients with metabolic syndrome: a randomized controlled trial.

High serum cholesterol is an important risk factor for cardiovascular events. It has been reported that regular blood donation is associated with a reduction in serum cholesterol. This study aimed to determine the effects of wet cupping on lipid profiles and anthropometric characteristics of patients with metabolic syndrome. One hundred and thirty-six patients aged 18-65 years with metabolic syndrome were recruited to participate in this trial. Ten patients were excluded due to exclusion criteria. Patients (n = 126) were randomly assigned into the control (n = 63) and experimental (n = 63) groups. Patients in the experimental group were treated with wet cupping combined with dietary advice. The controls were given dietary advice only. Anthropometric and biochemical parameters were assessed at baseline and at six and 12 weeks after treatment. The significance of the data was analyzed using a repeated measure ANOVA. The lipid profile status did not differ significantly between the two groups (p > 0.05) whereas there was a significant difference between the two time points within each group (p < 0.05). In addition, several anthropometric parameters improved in both groups, but this did not differ significantly between subject groups. Wet cupping does not have a significant effect on anthropometric or biochemical indices compared to the effect of dietary advice alone.

Effect of prenatal selenium supplementation on cord blood selenium and lipid profile.

BACKGROUND: Selenium is an essential trace element and as a component of selenoproteins it plays a key role as an antioxidant. We aimed to evaluate the effect of selenium supplementation during pregnancy on cord blood selenium content and lipid profile. METHODS: This trial was performed on 166 eligible women who were randomized to receive 100 µg of selenium, as selenium-yeast (Se group) or a placebo-yeast tablet (placebo group). Umbilical cord blood samples were collected at the time of delivery and selenium concentration and lipid profile were measured. RESULTS: Triglyceride levels were found to be significantly higher in the Se group than in the placebo group (p=0.01). However, no significant difference in cord blood selenium was observed between the groups nor were there any significant correlations between cord blood selenium and lipid profile parameters. CONCLUSION: Our findings suggest that selenium supplementation in pregnant women may be associated with an increased cord-blood triglyceride level, although total cholesterol, low-density lipoprotein and high-density lipoprotein cholesterol levels did not change significantly. The clinical significance of the increased cord triglyceride concentration needs to be evaluated.

Effect of supplementation with selenium on postpartum depression: a randomized double-blind placebo-controlled trial.

OBJECTIVE: Postpartum depression is a common complication of childbirth, and its prevention is an important public-health issue because of its negative effects on mother, infant, and family. The present randomized, double-blind, placebo-controlled trial was conducted to examine the effect of prenatal selenium supplementation on the postpartum depression level in Iranian women. DESIGN: A total of 166 primigravid pregnant women in the first trimester of pregnancy, were randomized to receive 100 µg of selenium (n = 83) or a placebo (n = 83) per day until delivery. The symptoms of postpartum depression were evaluated during the eight weeks following delivery by means of the Edinburgh Postnatal Depression Scale (EPDS). Serum selenium concentrations were measured at baseline and at the end of study. RESULTS: There was no significant difference in demographic characteristics and perceived social support between the selenium and control groups at baseline (p > 0.05). There were 22 drop-outs in the selenium-supplemented group and 19 in the placebo group. Forty-four women in the selenium group and 41 women in the placebo group completed the trial and the EPDS questionnaire. Selenium supplementation was associated with a significant increase in mean serum selenium concentration at term (p < 0.001) but remained unchanged in the control group. The mean EPDS score in the selenium group was significantly lower than that of the control group (p < 0.05). CONCLUSION: These findings suggest that supplementation with selenium during pregnancy might be an effective approach for the prevention of postpartum depression.
