OBJECTIVE:
To study the effects of buckwheat-oat-pea (BOP) composite flour [buckwheat ∶ oats ∶ peas=6 ∶ 1 ∶ 1 (quality ratio)] on blood glucose in diabetic rats.
METHODS:
In this study, 64 male Sprague-Dawley rats were divided into 8 groups by fasting blood glucose (FBG) and body weight: normal control group, model control group, metformin group, buckwheat group, oats group, BOP low-dose group (BOP-L), medium-dose group (BOP-M), and high-dose group (BOP-H). The rats in the normal control group were fed with normal diet, the rats in the model control group and metformin group were fed with a high-fat diet (HFD), and the rats in the buckwheat group, oats group, and BOP-L, BOP-M, BOP-H groups were fed with HFD containing 10% buckwheat flour, 10% oat flour, 3.3% BOP, 10% BOP, 30% BOP, respectively. The HFD in all the groups had the same percentage of energy from fat (45%). After 30 days, the rats fed with HFD received intraperitoneal injection of streptozotocin (30 mg/kg, once a week for two weeks) to establish diabetes mellitus. After the model was successful established, the rats were fed for another 28 days. During the study, the body weight, food intake/body weight (FI/BW) and water intake/body weight (WI/BW), food utilization rate, 24 h urine volume, FBG, glucose area under curve (GAUC) of oral glucose tolerance test were measured regularly. At the end of the study, the fasting serum glucose and insulin were measured, and homeostasis model assessment of insulin resistance (HOMA-IR) was calculated.
RESULTS:
With the inducing of HFD and streptozotocin, compared with the normal control group, the rats in the model control group had higher FI/BW, WI/BW, 24 h urine volume, FBG, GAUC, HOMA-IR (P < 0.05), and lower body weight, food utilization rate (P < 0.05). Compared with the model control group, the rats in the three BOP groups all had higher body weight, food utilization rate (P < 0.05), and lower WI/BW, HOMA-IR (P < 0.05); the rats in the BOP-L and BOP-M groups had lower FI/BW, 24 h urine volume, FBG (P < 0.05), and the rats in the BOP-M group also had lower GAUC (P < 0.05). After the establishment of diabetes, there was no significant difference in blood glucose and the other indicators between the rats in the three BOP groups and the buckwheat group or the oats group (P>0.05).
CONCLUSION
The BOP had the effects of reducing blood glucose, insulin resistance and diabetic symptoms on diabetic rats, and had the value for further development and utilization.

BACKGROUND/AIMS: There is limited data to compare the clinical characteristics and recurrence rates between left-sided primary epiploic appendagitis (PEA) versus left-sided acute colonic diverticulitis (ACD), and right-sided PEA versus right-sided ACD, respectively.METHODS: We retrospectively reviewed the medical records and radiologic images of the patients who presented with left-sided or right-sided acute abdominal pain and had computer tomography performed at the time of presentation showing radiological signs of PEA or ACD between January 2004 and December 2014. We compared the clinical characteristics of left PEA versus left ACD and right PEA versus right ACD, respectively.RESULTS: Fifty-six patients (left:right = 27:29) and 308 patients (left:right = 24:284) were diagnosed with symptomatic PEA and ACD, respectively. Left-sided PEA were statistically significantly younger (50.2 ± 15.4 years vs. 62.1 ± 15.8 years, P= 0.009), more obese (body mass index [BMI]: 26.3 ± 2.9 kg/m² vs. 22.3 ± 3.1 kg/m² , P< 0.001), and had more tendencies with normal or mildly elevated high-sensitivity C-reactive protein (hsCRP) (1.2 ± 1.3 mg/dL vs. 8.4 ± 7.9 mg/dL, P< 0.001) than patients with left-sided ACD. The discriminative function of age, BMI and CRP between left-sided PEA versus left-sided ACD was 0.71 (cutoff: age ≤ 59 years, sensitivity of 66.7%, specificity of 77.8%), 0.84 (cutoff: BMI > 24.5 kg/m² , sensitivity of 80.0%, specificity of 80.0%) and 0.80 (cutoff: CRP < 1.8 mg/dL, sensitivity of 72.2%, specificity of 85.7%).CONCLUSIONS: If patients with left lower quadrant abdominal pain are less than 60 years, obese (BMI > 24.5 kg/m² ) with or without normal to mild elevated CRP levels (CRP < 1.8 mg/dL), it might be necessary for clinicians to suspect the diagnosis of PEA rather than ACD.

BACKGROUND/OBJECTIVES: Ultraviolet radiation (UV) is a major cause of skin photoaging. Previous studies reported that ethanol extract (PET) of Prunus persica (L.) Batsch flowers (PPF, peach flowers) and its subfractions, particularly the ethylacetate (PEA) and n-butanol extracts (PBT), have potent antioxidant activity and attenuate the UV-induced matrix metalloproteinase (MMP) expression in human skin cells. In this study, we investigated the protective activity of PPF extract against UV-induced photoaging in a mouse model. MATERIALS/METHODS: Hairless mice were treated with PET or a mixture of PEA and PBT either topically or orally along with UV irradiation. Histological changes and biochemical alterations of mouse skin were examined. Major phenolic compounds in PPF extract were analyzed using an ACQUITY UPLC system. RESULTS: The overall effects of topical and oral treatments with PPF extract on the UV-induced skin responses exhibited similar patterns. In both experiments, the mixture of PEA and PBT significantly inhibited the UV-induced skin and epidermal thickening, while PET inhibited only the UV-induced epidermal thickening. Treatment of PET or the mixture of PEA and PBT significantly inhibited the UV-induced MMP-13 expression, but not typeⅠ collagen expression. Topical treatment of the mixture of PEA and PBT with UV irradiation significantly elevated catalase, superoxide dismutase (SOD) and glutathione-peroxidase (GPx) activities in the skin compared to those in the UV irradiated control group, while oral treatment of the mixture of PEA and PBT or PET elevated only catalase and SOD activities, but not GPx. Thirteen phytochemical compounds including 4-O-caffeoylquinic acid, cimicifugic acid E and B, quercetin-3-O-rhamnoside and kaempferol glycoside derivatives were identified in the PPF extract. CONCLUSIONS: These results demonstrate that treatment with PET or the mixture of PEA and PBT, both topically or orally, attenuates UV-induced photoaging via the cooperative interactions of phenolic components having anti-oxidative and collagen-protective activities.

BACKGROUND: The treatment of choice for chronic thromboembolic pulmonary hypertension (CTEPH) is pulmonary endarterectomy (PEA). However, not all patients are eligible for PEA, and some patients experience recurrence of pulmonary hypertension even after PEA. METHODS: Patients who underwent balloon pulmonary angioplasty (BPA) between December 2015 and April 2017 were enrolled from the Samsung Medical Center CTEPH registry. Enrolled patients underwent right heart catheterization, echocardiography, and 6-minute walk distance (6MWD) at baseline, 4 and 24 weeks after their first BPA session. We compared clinical and hemodynamic parameters at the baseline and last BPA session. RESULTS: Fifty-two BPA sessions were performed in 15 patients, six of whom had a history of PEA. BPA resulted in improvements in World Health Organization (WHO) functional class (2.9 ± 0.8 to 1.7 ± 0.6, P = 0.002), 6MWD (387.0 ± 86.4 to 453.4 ± 64.8 m, P = 0.01), tricuspid annular plane systolic excursion (14.1 ± 3.6 to 15.6 ± 4.3 mm, P = 0.03) and hemodynamics, including a decline in mean pulmonary artery pressure (41.1 ± 13.1 to 32.1 ± 9.5 mmHg, P < 0.001) and in pulmonary vascular resistance (607.4 ± 452.3 to 406.7 ± 265.4 dyne.sec.cm−5, P = 0.01) but not in cardiac index (2.94 ± 0.79 to 2.96 ± 0.93 L/min/m2, P = 0.92). Six cases of complications were recorded, including two cases of reperfusion injury. CONCLUSION: BPA might be a safe and effective treatment strategy for both inoperable CTEPH patients and patients with residual pulmonary hypertension after PEA.

The purpose of this research was to provide basic information for cookies made with black soybeans, chick peas, lentils, oatmeal, and brewer's yeast and to establish the optimum formula for the development of low glycemic index (GI) cookies with high biotin content for lactating women. This study was performed to determine the optimal composite recipe of oatmeal cookies with two different concentrations levels of bean powder (black soybeans, chick peas, lentils) and brewer's yeast using a central composite design. In addition, the mixing conditions of oatmeal cookies were optimized using response surface methodology of sensory evaluation and mechanical and physicochemical analysis. As a result, mechanical and physicochemical analyses showed significant values for lightness, redness, yellowness, hardness, and water content (P < 0.05), while sensory evaluation showed significant values for flavor, taste, crispness, and overall acceptability (P < 0.05). The optimal sensory combination was suggested to be 3.73 g of bean powder and 1.59 g of brewer's yeast. Considering all outcomes obtained throughout the experiments, brewer's yeast, black soybeans, chick peas, lentils, and oatmeal are suitable ingredients for increasing functionality and consumer acceptability of cookies. In addition, these results are expected to be useful in producing cookies of optimal quality, contributing to the development of various nutritious foods, and improving the food industry for lactating women.

Clitoria ternatea or Commonly known blue pea, is a perennial climber crop native to Asian countries. The current study was aimed to evaluate the antimicrobial activity C. ternatea extract on food borne microorganisms and its antifungal effect on Penicillium expansum. The extract showed significant antimicrobial activity against 3 Gram positive bacteria, 2 Gram negative bacteria and 1 filamentous fungus on disc diffusion assay. The extract also showed good biocidal effect on all Gram positive bacteria tested and P. expansum. However, the kill curve analysis revealed that the fungicidal activity of the extract against P. expansum conidia was depend on the concentration of the extract and the time of exposure of the conidia to the extract. The scanning electron micrograph of the extract treated P. expansum culture showed alterations in the morphology of fungal hyphae. The germination of P. expansum conidia was completely inhibited and conidial development was totally suppressed by the extract, suggesting the possible mode of action of anthocyanin. Besides, the extract also exhibited 5.0-log suppression of microbial growth relative to control in the rice model. The results indicate the potential use of the C. ternatea anthocyanin as food biopreservative.

BACKGROUND: A growing body of evidence suggests that neuroinflammation, which is characterized by infiltration of immune cells, activation of mast cells and glial cells, and production of inflammatory mediators in the peripheral and central nervous systems, plays an important role in the induction and maintenance of chronic pain. Palmitoylethanolamide (PEA), which is a type of N-acylethanolamide and a lipid, has an anti-inflammatory effect. Relative to the anti-inflammatory effect, little is known about its analgesic effect in chronic pain. This study aimed to determine whether PEA relieves chronic inflammatory and neuropathic pain. METHODS: Male Sprague-Dawley rats were injured by transection of the left L5 and L6 spinal nerves to induce neuropathic pain or were injected with monoiodoacetic acid into the synovial cavity of knee joints to induce inflammatory pain. To assess the degree of pain, two kinds of stimuli - pressing von Frey filaments and wetting with acetone - were applied to the plantar surface of the rat to measure mechanical and cold sensitivity, respectively. Pain was measured by assessing behavioral responses, including paw withdrawal response threshold and paw withdrawal frequency upon stimulation. RESULTS: Neuropathic pain caused by spinal nerve transection (SNT) decreased the mechanical threshold and increased the frequency of response to acetone application. But, cold allodynia caused by SNT did not decrease the withdrawal frequency. Mechanical hyperalgesia caused by chronic inflammation was significantly reduced by both intraperitoneal and intra-articular injections of PEA. CONCLUSIONS: These outcomes revealed that PEA might be effective in relieving inflammatory and neuropathic pain, especially pain induced by mechanical hyperalgesia, but not cold allodynia.

BACKGROUND/AIMS: Pulmonary endarterectomy (PEA) is the gold standard for treating chronic thromboembolic pulmonary hypertension (CTEPH) in Western countries. The aim of this study was to investigate the long-term outcomes of performing PEA on CTEPH patients in comparison with medical therapy at a single Korean center. METHODS: This retrospective study included 88 CTEPH patients. These patients were classified into the PEA group (n = 37) or non-PEA group (i.e., medical therapy; n = 51). The clinical characteristics, hemodynamic data, and long-term survival rates were compared. Independent prognostic factors for CTEPH were also investigated. RESULTS: CTEPH was not associated with either gender, and the mean age at diagnosis was 53.3 ± 13.7 years. Echocardiography revealed that the mean peak velocity of the tricuspid regurgitation jet was 4.2 ± 0.7 m/sec and the mean pulmonary arterial pressure was 51.7 ± 15.1 mmHg. The PEA and non-PEA groups demonstrated no significant differences, except in terms of the right ventricular end-diastolic diameter. The survival rates of the PEA group were significantly higher than the non-PEA group at 1, 3, 5, and 10 years (p = 0.032). Multivariate analyses indicated that World Health Organization class IV and PEA were significant predictors of poorer and better outcomes, respectively. CONCLUSIONS: PEA demonstrates more favorable effects on long-term survival than medical therapy in Korean CTEPH patients who were considered operable.

9.Pulseless electrical activity during general anesthesia induction in patients with amyotrophic lateral sclerosis.
Journal of Dental Anesthesia and Pain Medicine 2017;17(3):235-240
Pulseless electrical activity (PEA) is a clinical condition characterized by unresponsiveness and lack of palpable pulse in the presence of organized cardiac electrical activity and is caused by a profound cardiovascular insult (e.g., severe prolonged hypoxia or acidosis, extreme hypovolemia, or flow-restricting pulmonary embolus). Amyotrophic lateral sclerosis (ALS) is a disease that is characterized by progressive degeneration of all levels of the motor nervous system. Damage to the respiratory system and weakness of the muscles may increase the likelihood of an emergency situation occurring in patients with ALS while under general anesthesia. We report a case of PEA during the induction of general anesthesia in a patient with ALS who presented for dental treatment and discuss the causes of PEA and necessary considerations for general anesthesia in patients with ALS.

The present study evaluated the effects of glyphosate on Pisum sativum germination as well as its effect on the physiology and biochemistry of germinated seedlings. Different physico-chemical biomarkers, viz., chlorophyll, root and shoot length, total protein and soluble sugar, along with sodium and potassium concentration, were investigated in germinated seedlings at different glyphosate concentrations. This study reports the influence of different concentrations of glyphosate on pea seeds and seedlings. Physicochemical biomarkers were significantly changed by glyphosate exposure after 15 days. The germination of seedlings under control conditions (0 mg/L) was 100% after 3 days of treatment but at 3 and 4 mg/L glyphosate, germination was reduced to 55 and 40%, respectively. Physiological parameters like root and shoot length decreased monotonically with increasing glyphosate concentration, at 14 days of observation. Average root and shoot length (n=30 in three replicates) were reduced to 14.7 and 17.6%, respectively, at 4 mg/L glyphosate. Leaf chlorophyll content also decreased, with a similar trend to root and shoot length, but the protein content initially decreased and then increased with an increase in glyphosate concentration to 3 mg/L. The study suggests that glyphosate reduces the soluble sugar content significantly, by 21.6% (v/v). But internal sodium and potassium tissue concentrations were significantly altered by glyphosate exposure with increasing concentrations of glyphosate. Biochemical and physiological analysis also supports the inhibitory effect of glyphosate on seed germination and biochemical effects on seedlings.
