Abstract Title: 

Coenzyme Q10 supplementation reverses diabetes-related impairments in long-term potentiation induction in hippocampal dentate gyrus granular cells: An in vivo study.

Abstract: 

Diabetes mellitus (DM) is associated with impaired hippocampal synaptic plasticity. Coenzyme Q10 (CoQ10) acts as an antioxidant and exerts neuroprotective effects. Accordingly, this study aimed at evaluating the effects of CoQ10 on hippocampal long-term potentiation (LTP) and paired-pulse facilitation (PPF) in streptozotocin (STZ)-induced diabetic rats. Male Wistar rats were randomly divided into six groups (n = 8 per group) as follows and treated for 90 days: the control, control + low dose of CoQ10 (100 mg/kg), control + high dose of CoQ10 (600 mg/kg), diabetic, diabetic + low dose of CoQ10, and diabetic + high dose of CoQ10 groups. Diabetes was induced by a single intraperitoneal injection of 50 mg/kg STZ. The population spike (PS) amplitude and slope of excitatory post synaptic potentials (EPSPs) were measured in dentate gyrus (DG) area in response to the stimulation applied to the perforant path (PP). The results showed that the STZ-induced diabetes impaired LTP induction in the PP-DG synapses. This finding is supported by the decreased EPSP slope and PS amplitude of LTP (P

Abstract Title: 

Coenzyme Q10 supplementation acts as antioxidant on dystrophic muscle cells.

Abstract: 

Increased oxidative stress is a frequent feature in Duchenne muscular dystrophy (DMD). High reactive oxygen species (ROS) levels, associated with altered enzyme antioxidant activity, have been reported in dystrophic patients and mdx mice, an experimental model of DMD. In this study, we investigated the effects of coenzyme Q10 (CoQ10) on oxidative stress marker levels and calcium concentration in primary cultures of dystrophic muscle cells from mdx mice. Primary cultures of skeletal muscle cells from C57BL/10 and mdx mice were treated with coenzyme Q10 (5μM) for 24 h. The untreated mdx and C57BL/10 muscle cells were used as controls. The MTT and live/dead cell assays showed that CoQ10 presented no cytotoxic effect on normal and dystrophic muscle cells. Intracellular calcium concentration, HOproduction, 4-HNE, and SOD-2 levels were higher in mdx muscle cells. No significant difference in the catalase, GPx, and Gr levels was found between experimental groups. This study demonstrated that CoQ10 treatment was able to reduce levels of oxidative stress markers, such as HO, acting as an antioxidant, as well as decreasing abnormal intracellular calcium influx in dystrophic muscles cells. This study demonstrated that CoQ10 treatment was able to reduce levels of oxidative stress markers, such as HO, acting as an antioxidant, as well as decreasing abnormal intracellular calcium influx in dystrophic muscles cells. Our findings also suggest that the decrease of oxidative stress reduces the need for upregulation of antioxidant pathways, such as SOD and GSH.

Abstract Title: 

Qigong exercise for chronic fatigue syndrome.

Abstract: 

Chronic fatigue syndrome (CFS) is often overlooked, has unclear etiology and no effective cure except some symptomatic treatments. Additionally, most people with CFS do not seek medical attention. Qigong exercise, an ancient Eastern body-mind-spirit practice, has been long practiced in Chinese communities and may powerfully trigger the self-healing process. Using full baseline data (n=1409), the average Hong Kong CFS respondent was found to be female, married, 42.5yo, highly educated and employed full-time, experiencing sleep disturbance (~95%), anxiety (>80%), and depressive symptoms (68%). Here, we summarized our previous studies to evaluate the potential of Qigong as a complementary and alternative therapy for CFS. Two randomized controlled trials were conducted (RCT1 n=137, RCT2 n=150). In both trials, extensive online questionnaires allowed individuals with CFS-like illness (i.e., symptoms match CFS, yet without clinical confirmation) to be identified. RCT1 included a 5-week intervention. The intervention in RCT2 was 8weeks. In RCT1 Qigong group had reduced fatigue (P

Abstract Title: 

The beneficial effects of Qigong on elderly depression.

Abstract: 

Health Qigong, especially the Eight-Section Brocades (or Baduanjin), has been well established as an effective adjunct intervention to alleviate depressive symptoms of older adults. The easy to learn and safe format of health Qigong allows the promotion and employment by health care professionals to improve the physical and psychosocial wellness of older adults. The cultural relevance of Qigong practice enhances its popularity as a health maintenance practice in Chinese community. In general, the antidepressive effects of Qigong are put forward through psychosocial, physiological, and neurobiological mechanisms. More specific, the beneficial effects of Qigong can be further substantiated by findings of several research studies.

Abstract Title: 

Artemisinin attenuates the development of atherosclerotic lesions by the regulation of vascular smooth muscle cell phenotype switching.

Abstract: 

AIMS: The purpose of this study was to investigate the therapeutic effect of artemisinin (ART) on atherosclerosis and explore the molecular mechanisms involved by RNA sequencing (RNA-Seq).MAIN METHODS: Eight-week-old male ApoEmice were treated with ART for eight weeks. Atherosclerotic lesion sizes were determined by Oil Red O staining, and RNA-Seq was used to detect the profile of differentially expressed genes following the administration of ART. The expressions of contractile phenotypic markers were detected by western blot and qRT-PCR, and the ability of the MOVAS cells to migrate and proliferate were assessed using the wound healing and CCK8 assays.KEY FINDINGS: Artemisinin treatment significantly reduced plaque area in the ApoEmice and increased the expression of contractile phenotypic markers. RNA-Seq of aorta tissue revealed a distinct change in gene expression patterns after the mice were treated with ART. Our bioinformatics analysis demonstrated that the most prominently enriched pathway was a set of genes involved in vascular smooth muscle contractile function. Using an in vitro cell model, we demonstrated that ART could effectively reverse PDGF-activated MOVAS migration and proliferation, and elevate the level of proteins involved in the contractile phenotype.SIGNIFICANCE: We provide in vivo and in vitro evidence supporting a role for ART in the suppression of atherosclerosis, partly through the inhibition of vascular smooth muscle cell phenotype switching to a de-differentiated phenotype. These data further advances our understanding for a potential role for ART and suggests that ART is an excellent candidate for the treatment of atherosclerosis.

Abstract Title: 

GALLIC ACID IMPROVES OXIDATIVE STRESS AND INFLAMMATION THROUGH REGULATING MICRORNAS EXPRESSIONS IN THE BLOOD OF DIABETIC RATS.

Abstract: 

Context: Endothelial dysfunction and diabetic cardiomyopathy are critical complications of diabetes. Gallic acid (GA) plays a significant role in cardiovascular disorders resulted from diabetes. In addition, increased plasma miR-24, miR-126 associated with endothelial dysfunction.Aim: The current study was designed to assess the effects of GA on plasma miR-24, miR-126 levels in the diabetic rats.Animals and Methods: Adult male Sprague-Dawley rats were divided into three groups (n=8): control (C), diabetic (D) and diabetic group treated with GA (D+G, 25 mg/kg, by gavage) for eight weeks. The blood glucose level, body weight, lipid profile, blood pressure, plasma miR-24 and miR-126 levels, antioxidant and inflammatory biomarkers were measured.Results: The plasma levels of miR-24, miR-126, body weight, high-density lipoprotein cholesterol (HDL-c), total anti-oxidant capacity (TAC) and the systolic blood pressure significantly reduced and blood glucose, total cholesterol (TC), triglycerides (TG), very low-density lipoprotein cholesterol (VLDL-c), malondialdehyde (MDA), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α) and low-density lipoprotein cholesterol (LDL-c) significantly elevated among the diabetic rats compared with the control group. However, GA restored body weight, blood pressure, TC, TG, VLDL-c, TNF-α, miR-126, blood glucose, HDL-c, MDA, TAC, miR-24 and IL-6 among the GA treated rats compared with the diabetic group.Conclusion: GA improves inflammation, oxidative stress and hypotension result from diabetes. These protective effects are probably mediated via increasing plasma miR-24 and miR-126 levels.

Abstract Title: 

Prevention of cadmium-induced neurotoxicity in rats by essential nutrients present in nuts.

Abstract: 

Cadmium, a heavy metal with no physiological function in the human body, is considered a bio-hazard. It is also considered to be a potent neurotoxin. The primary sources of cadmium exposure are diet and cigarette smoke. It has been postulated that nutritional deficiencies can increase the risk of cadmium toxicity. Nuts provide essential nutrients which are necessary for the maintenance of brain health in humans. The present study was designed to investigate the possible protective effects of almond and walnut supplementation on cadmium-induced neurotoxicity. Cadmium was orally administered at a dose of 50 mg/kg weekly with or without the supplementation of almond and walnut in rats. Intensities of depression‑ and anxiety-related behaviors were assessed by the forced swim test and light/dark transition test, respectively. Memory function was also evaluated by the elevated plus maze, Morris water maze and novel object recognition task. After four weeks of treatment it was observed that cadmium administration significantly induced depressogenic and anxiogenic behaviors. Memory function was also impaired by cadmium administration. Cadmium-treated rats exhibited reduced noradrenalin, dopamine and serotonin levels in the brain, whereas the levels of their respective metabolites were significantly increased. The dietary supplementation of almond and walnut at a dose of 400 mg/kg/day significantly attenuated cadmium-induced depression, anxiety and memory impairments. Neurochemical aberrations also normalized following supplementation with these nuts in rats. The present study demonstrates that long-term supplementation with almond and walnut provides essential nutrients which may overcome nutritional deficiencies and thereby reduce heavy-metal intoxication.

Abstract Title: 

Prospective randomized controlled pilot study on the effects of almond consumption on skin lipids and wrinkles.

Abstract: 

OBJECTIVE: Almonds are a rich source of fatty acids and antioxidants, and their supplementation is known to significantly modulate serum lipids. The effects of almond on the skin's lipid barrier and the appearance of wrinkles have not yet been elucidated. The aim of this study was to investigate the effects of almond consumption on facial sebum production and wrinkles.METHODS: This was a prospective, investigator-blinded, randomized controlled trial in which subjects consumed 20% of their daily energy consumption in either almonds or a calorie-matched snack for 16 weeks. This study was completed at the UC Davis Dermatology clinic. Participants were a volunteer sample of generally healthy postmenopausal females with Fitzpatrick skin types 1 and 2. A facial photograph and image analysis system was used to obtain standardized photographs and information on wrinkle width and severity at 0, 8, and 16 weeks. Measurements of transepidermal water loss and sebum production were also completed at 0, 8, and 16 weeks.RESULTS: Fifty healthy postmenopausal females were recruited, 31 participants were enrolled, and 28 completed the study. Under photographic analysis, the almond group had significantly decreased wrinkle severity and width compared with the control group at 16 weeks (p
