The physicochemical properties and sensory analysis of duck meatballs containing duck meat surimi-like material during frozen storage were evaluated. Properties of meatballs containing duck surimi-like material prepared by acid solubilization (ACDS), alkaline solubilization (ALDS), and conventional processing (CDS) as well as duck mince (as the control, CON) were compared. ACDS had significantly higher (P < 0.05) moisture and protein content and lower fat content compared with CON. The thiobarbituric acid-reactive substances (TBARS) value of all samples increased as the storage time increased up to week 8 (P < 0.05), but thereafter it decreased in most of the samples. ACDS and ALDS had significantly higher TBARS values (P < 0.05), and these values remained higher than those of the other samples throughout the frozen storage period. Addition of surimi-like material to the meatballs had significant effects (P < 0.05) on springiness, gumminess, and chewiness values of all samples. Ingredients and frozen storage affected most sensory attributes in samples significantly (P<0.05). No significant increase in growth of organisms occurred during 12-wk frozen storage The results indicate that acid-alkaline solubilization methods improve both physicochemical and sensory properties of duck meatballs containing duck surimi-like material. Thus, these techniques should be applicable to product development of duck surimi-like material.
Capsular serotypes K1 and K2 of Klebsiella pneumoniae are thought to the major virulence determinants responsible for liver abscess. The intestine is one of the major reservoirs of K. pneumoniae, and epidemiological studies have suggested that the majority of K. pneumoniae infections are preceded by colonization of the gastrointestinal tract. The possibility of fecal-oral transmission in liver abscess has been raised on the basis of molecular typing of isolates. Data on the serotype distribution of K. pneumoniae in stool samples from healthy individuals has not been previously reported. This study investigated the seroepidemiology of K. pneumoniae isolates from the intestinal tract of healthy Chinese in Asian countries. Stool specimens from healthy adult Chinese residents of Taiwan, Japan, Hong Kong, China, Thailand, Malaysia, Singapore, and Vietnam were collected from August 2004 to August 2010 for analysis.
The Asian College of Psychosomatic Medicine (ACPM) was founded as the Asian Chapter of the International College of Psychosomatic Medicine (ICPM-AC) in Tokyo on April 12, 1982.The first president was Hitoshi ISHIKAWA (Japan), the vice-presidents were Mahalingam MAHADEVAN (Malaysia) and Burton G.BURTON-BRADLEY (Papua- New Guinea), and the general secretary was Sueharu TSUTSUI (Japan).Five years previously, preparation for creation of the ICPM-AC was started at the 4th World Congress of the International College of Psychosomatic Medicine (ICPM) held in Kyoto, Japan, September 5-9, 1977.The First Congress of the ICPM-AC was held by the President Yujiro IKEMI in Tokyo on May 19-20, 1984. The main members in the early stage were Y. IKEMI, H. ISHIKAWA, S. TSUTSUI, Taisaku KATSURA, Tetsuya NAKAGAWA. Hiroyuki SUEMATSU and others from Japan and Hsien RIN (Taiwan), Seock Young KANG (Korea), M. MAHADEVAN. B.G. BURTON-BRADLEY and others from other Asian countries.Thereafter, academic congresses of the ICPM-AC, the 2nd to the 9th, were held approximately every two years, in Japan, India, Malaysia, Taiwan, Korea, and China. The name was changed to the Asian College of Psychosomatic Medicine (ACPM), and the 10th to 14th congresses were held in Taiwan, Okinawa (Japan), Australia, Korea, and China.The current president of the Executive Board of ACPM is Chiharu KUBO, the Director of Kyushu University Hospital.The next academic congress is the 15th ACPM and will be hosted by Tserenkhuugyin LKHAGVASUREN in Ulaanbaatar, Mongolia from August 24-26, 2012.Participating countries have expanded to include Asian-Oceanic countries such as Mongolia, Micronesia, Australia and Sri Lanka.The main themes of the congresses have focused on psychosomatic disorders, culture - bound syndromes, oriental medicine, etc... To date,"Health promotion"by raising the level of mental health based on psychoneuroendocrinoimmunomodulation has been very important. Prevention is also important in the Asia - Oceana area, from the viewpoints of both psychosomatics and culture.Above all, an awareness of existential, authentic health is a sure way to promote healthy longevity and psychosomatic well - being.To pursue happiness and well-being subjectively, objectively, and ecologically will be the most important purposes of ACPM in the future.
Opisthioglyphe sharmai n. sp. is described from the gall bladder of the Malayan box turtle, Cuora amboinensis, and the black marsh turtle, Siebenrockiella crassicollis, in Malaysia. The new species is morphologically similar to Opisthioglyphe ranae and some other members of the genus parasitic in amphibians and reptiles. Opisthioglyphe sharmai n. sp. is easily differentiated from all other members of the genus by the cirrus sac extending posterior to the ventral sucker, while in all previously known species the cirrus sac is entirely or mostly preacetabular with the base of the structure not reaching beyond mid-line of the ventral sucker. Despite the overall stable morphology, O. sharmai n. sp. is characterized by highly variable arrangement of testes, from tandem to opposite. It is only the second representative of the genus described from turtles and the first species of Opisthioglyphe parasitic in gall bladder, while all previously described members of the genus are parasitic in the intestine of their hosts.
The objective of this study was to evaluate the effects of ultraviolet (UV) radiation (UVB; 90 J/m²) on growth, bioconversion of isoflavones and probiotic properties of parent and subsequent passages of L. casei FTDC 2113. UV radiation significantly enhanced (P < 0.05) the growth of parent cells in mannitol-soymilk fermented at 37°C for 24 h. This had led to an enhanced intracellular and extracellular β-glucosidase activity with a subsequent increase in bioconversion of isoflavones in mannitol-soymilk (P < 0.05). UV radiation also promoted (P < 0.05) the tolerance of parent cells towards acidic condition (pH 2 and 3) and intestinal bile salts (oxgall, taurocholic and cholic acid). In addition, parent treated cells also exhibited better (P < 0.05) adhesion ability to mucin and antimicrobial activity compared to that of the control. All these positive effects of UV radiation were only prevalent in the parent cells without inheritance by first, second and third passage of cells. Although temporary, our results suggested that UV radiation could enhance the bioactive and probiotic potentials of L. casei FTDC 2113, and thus could be applied for the production of probiotic products with enhanced bioactivity.
Stroke is one of the top five leading causes of death and one of the top 10 causes for hospitalization in Malaysia. Stroke is also in the top five diseases with the greatest burden of disease, based on disability-adjusted life years. However, prospective studies on stroke in Malaysia are limited. To date, neither the prevalence of stroke nor its incidence nationally has been recorded. Hypertension is the major risk factor for stroke. The mean age of stroke patients in Malaysia is between 54.5 and 62.6 years. Traditional medicine is commonly practiced. With the increasing number of stroke cases annually, more government and nongovernment organizations should be involved in primary and secondary prevention strategies.

The aim of this study was to evaluate the effect of ultrasound on the intestinal adherence ability, cell growth, and cholesterol removal ability of parent cells and subsequent passages of Lactobacillus fermentum FTDC 1311. Ultrasound significantly decreased the intestinal adherence ability of treated parent cells compared to that of the control by 11.32% (P<0.05), which may be due to the protein denaturation upon local heating. Growth of treated parent cells also decreased by 4.45% (P<0.05) immediately upon ultrasound (0-4h) and showed an increase (P<0.05) in the viability by 2.18-2.34% during the later stage of fermentation (12-20 h) compared to that of the control. In addition, an increase (P<0.05) in assimilation of cholesterol (>9.74%) was also observed for treated parent cells compared to that of the control, accompanied by increased (P<0.05) incorporation of cholesterol into the cellular membrane. This was supported by the increased ratio of membrane cholesterol:phospholipids (C:P), saturation of cholesterol in the apolar regions, upper phospholipids regions, and polar regions of membrane phospholipids of parent cells compared to that of the control (P<0.05). However, such traits were not inherited by the subsequent passages of treated cells (first, second, and third passages). Our data suggested that ultrasound treatment could be used to improve cholesterol removal ability of parent cells without inducing permanent damage/defects on treated cells of subsequent passages.
A simple, environmental friendly and selective sample preparation technique employing porous membrane protected micro-solid phase extraction (μ-SPE) loaded with molecularly imprinted polymer (MIP) for the determination of ochratoxin A (OTA) is described. After the extraction, the analyte was desorbed using ultrasonication and was analyzed using high performance liquid chromatography. Under the optimized conditions, the detection limits of OTA for coffee, grape juice and urine were 0.06 ng g(-1), 0.02 and 0.02 ng mL(-1), respectively while the quantification limits were 0.19 ng g(-1), 0.06 and 0.08 ng mL(-1), respectively. The recoveries of OTA from coffee spiked at 1, 25 and 50 ng g(-1), grape juice and urine samples at 1, 25 and 50 ng mL(-1) ranged from 90.6 to 101.5%. The proposed method was applied to thirty-eight samples of coffee, grape juice and urine and the presence of OTA was found in eighteen samples. The levels found, however, were all below the legal limits.
A new poly(4-vinyl pyridine) (P4VP) based cadmium (Cd)-ion selective electrode (ISE) was developed. The 4-vinyl pyridine (4VP) was first polymerized electrochemically on the surface of graphite, later characterized by FTIR, SEM/EDX and then optimized as ISE for Cd. At optimal pH 6.4, slope of 27.7±0.8mVdecade(-1), linear concentration range of 1×10(-7) to 1.0×10(-1)M Cd(2+) and limit of detection (S/N=3) of 2.51×10(-8)M were obtained. The ISE was very selective towards Cd(2+), with K(pot)<1×10(-2) in the presence of the usual cations and anions in water samples. Response time and shelf life of less than 1min and 90 days, respectively, were observed. Its application was tested in various types of samples.
This paper reports a computational approach for analysis of FTIR spectra where peaks are detected, assigned and matched across samples to produce a peak table with rows corresponding to samples and columns to variables. The algorithm is applied on a dataset of 103 spectra of a broad range of edible oils for exploratory analysis and variable selection using Self Organising Maps (SOMs) and t-statistics, respectively. Analysis on the resultant peak table allows the underlying patterns and the discriminatory variables to be revealed. The algorithm is user-friendly; it involves a minimal number of tunable parameters and would be useful for analysis of a large and complicated FTIR dataset.
This study aimed to determine the relationship between child feeding practices, food habits, and anthropometric indicators with cognitive performance of preschoolers aged 4-6 years in Peninsular Malaysia (n=1933). Parents were interviewed on socio-demographic background, nutrition knowledge, child feeding practices and food habits. Height and weight of the preschoolers were measured; BMI-for-age, weight-for-age and height-for-age were determined. Cognitive performance was assessed using Raven's Colored Progressive Matrices. The mean monthly household income was RM3610 and 59.6% of parents attained secondary education. Thirty-three percent of parents had good knowledge on nutrition, 39% satisfactory and 28% poor. For child feeding practices, perceived responsibility had the highest mean score (M=3.99, SD=0.72), while perceived child weight had the lowest (M=2.94, SD=0.38). The prevalence of possible risk of overweight, being overweight, and obesity were 3.9%, 7.9% and 8.1%, respectively, whereas the prevalence of underweight and stunting were 8.0% and 8.4%, respectively. Breakfast was the second most frequently skipped meal (16.8%) after dinner (18.1%). The mean cognitive score was 103.5 (SD=14.4). Height-for-age and consumption of dinner were found to contribute significantly towards cognitive performance after controlling for socio-demographic background and parent's nutrition knowledge.

AIMS: We examined the relationship of hypoglycemic symptoms with health-related quality of life and worry about hypoglycemia among type 2 diabetic patients using oral antihyperglycemic agents (AHA) in the Asia-Pacific region.
METHODS: A total of 2257 type 2 diabetic patients with at least 6 months of oral AHA were enrolled in China, Korea, Malaysia, Thailand, and Taiwan. Quality of life was measured with the EuroQol Visual Analog Scale (EQ-VAS) and EuroQol-5 Dimensions questionnaire (EQ-5D), and worry about hypoglycemia with the worry subscale of the Hypoglycemic Fear Survey-II (HFS).
RESULTS: The mean (SD) age was 58.7 (10.2) years and HbA(1c) was 7.5% (1.5). The proportion of patients with an HbA(1c) <6.5% and <7% was 24.9% and 41.8%, respectively. Hypoglycemic symptoms in the prior 6 months were reported by 35.8% of patients. Mean scores on the EQ-VAS and the EQ-5D were significantly lower for patients who had hypoglycemic symptoms compared to those who did not (73.6 vs. 76.9, p<0.001; 0.88 vs. 0.90, p<0.0001, respectively), whereas mean score on the HFS was significantly higher (12.5 vs. 6.3, p<0.001). In multivariate models, hypoglycemic symptoms were independently associated with scores on the EQ-5D, EQ-VAS, and HFS (all p ≤ 0.01-0.001). Symptom severity was positively associated with fear of hypoglycemia (all p ≤ 0.001).
CONCLUSION: Hypoglycemic symptoms were associated with reduced quality of life and increased patient worry in patients with type 2 diabetes treated with AHA.

An ultra-slow oscillation (<0.01 Hz) in the network-wide activity of dissociated cortical networks is described in this article. This slow rhythm is characterized by the recurrence of clusters of large synchronized bursts of activity lasting approximately 1-3 min, separated by an almost equivalent interval of relatively smaller bursts. Such rhythmic activity was detected in cultures starting from the fourth week in vitro. Our analysis revealed that the propagation motifs of constituent bursts were strongly conserved across multiple oscillation cycles, and these motifs were more consistent at the electrode level compared with the neuronal level.
Asthma is associated with increased pulmonary inflammation and airway hyperresponsiveness. The current use of corticosteroids in the management of asthma has recently raised issues regarding safety and lack of responsiveness in 5-10% of asthmatic individuals. The aim of the present study was to investigate the therapeutic effect of a non-steroidal small molecule that has cysteinyl leukotriene (cysLT) inhibitory activity, upon attenuation of allergic lung inflammation in an acute murine model. Mice were sensitized with ovalbumin (OVA) and treated with several intraperitoneal doses (100, 20, 2 and 0.2mg/kg) of 2,4,6,-trihydroxy-3-geranylacetophenone (tHGA). Bronchoalveolar lavage was performed, blood and lung samples were obtained and respiratory function was measured. OVA sensitization increased pulmonary inflammation and pulmonary allergic inflammation was significantly reduced at doses of 100, 20 and 2mg/kg with no effect at the lowest dose of 0.2mg/kg. The beneficial effects in the lung were associated with reduced eosinophilic infiltration and reduced secretion of Th2 cytokines and cysLTs. Peripheral blood reduction of total IgE was also a prominent feature. Treatment with tHGA significantly attenuated altered airway hyperresponsiveness as measured by the enhanced pause (Penh) response to incremental doses of methacholine. These data demonstrate that tHGA, a synthetic non-steroidal small molecule, can prevent acute allergic inflammation. This proof of concept opens further avenues of research and development of tHGA as an additional option to the current armamentarium of anti-asthma therapeutics.
Many recent studies investigated the prognostic value of new biomarkers in breast cancer using data from cancer registries. Some of these studies were conducted using only patients for whom biomarker status was available (or tested). Using human epidermal growth factor receptor 2 (HER2) as an example, we determined whether testing for a recently introduced biomarker was associated with the outcome of women with breast cancer.

Chromosomal aberrations of chromosome 16 are uncommon and submicroscopic deletions have rarely been reported. At present, a cytogenetic or molecular abnormality can only be detected in 55% of Rubinstein-Taybi syndrome patients, leaving the diagnosis in 45% of patients to rest on clinical features only. Interestingly, this microdeletion of 16 p13.3 was found in a young child with an unexplained syndromic condition due to an indistinct etiological diagnosis. To the best of our knowledge, no evidence of a microdeletion of 16 p13.3 with contiguous gene deletion, comprising cyclic adenosine monophosphate-response element-binding protein and tumor necrosis factor receptor-associated protein 1 genes, has been described in typical Rubinstein-Taybi syndrome.
One of the main indicators of the suspension system efficiency in lower limb prostheses is vertical displacement or pistoning within the socket. Decreasing pistoning and introducing an effective system for evaluating pistoning could contribute to the amputees' rehabilitation process.
A cyclodextrin-modified micellar electrokinetic chromatography (CD-MEKC) technique has been developed for enantioseparation of vinpocetine using an inexpensive 2-hydroxypropyl-β-CD (HP-β-CD) as the chiral selector (CS). The best chiral separation was achieved using 40 mM HP-β-CD as the CS in 50 mM phosphate buffer (pH 7.0) consisting of 40 mM sodium dodecyl sulfate (SDS) at a separation temperature and separation voltage of 25°C and 25 kV, respectively. To the author's best knowledge, this is the first CD-MEKC study able to successfully separate the four stereoisomer of vinpocetine in separation time of 9.5 min and resolution of 1.04-3.87.
