Cooper Pair Density of Bi2Sr2CaCu2O8+ x in Atomic scale at 4.2 K.

In pursuit of the elusive mechanism of high- T C superconductors (HTSC), spectroscopic imaging scanning tunneling microscopy (SI-STM) is an indispensable tool for surveying local properties of HTSC. Since a conventional STM utilizes metal tips, which allow the examination of only quasiparticles and not superconducting (SC) pairs, Josephson tunneling using STM has been demonstrated by many authors in the past. An atomically resolved scanning Josephson tunneling microscopy (SJTM), however, was realized only recently on Bi2Sr2CaCu2O8+ x (Bi-2212) below 50 mK and on the Pb(110) surface at 20 mK. Here we report the atomically resolved SJTM on Bi2Sr2CaCu2O8+ x at 4.2 K using Bi-2212 tips created in situ. The I- V characteristics show clear zero bias conductance peaks following Ambegaokar-Baratoff (AB) theory. A gap map was produced for the first time using an atomically resolved Josephson critical current map I C( r) and AB theory. Surprisingly, we found that this new gap map is anticorrelated to the gap map produced by a conventional method relying on the coherence peaks. Quasiparticle resonance due to a single isolated zinc atom impurity was also observed by SJTM, indicating that atomically resolved SJTM was achieved at 4.2 K. Our result provides a starting point for realizing SJTM at even higher temperatures, rendering possible investigation of the existence of SC pairs in HTSC above the T C.

Impact on mental health of the COVID-19 outbreak among community pharmacists during the sanitary lockdown period.

OBJECTIVES: COVID-19 outbreak can impact mental health including health care workers. The aim of this study was to assess the psychological impact of COVID-19 in French community pharmacists. MATERIAL AND METHODS: We carried out a postal-based survey to assess the psychological impact of COVID-19 in French owner community pharmacists based on three validated self-report questionnaires: Perceived Stress scale, Impact of Event Scale-revised and Maslach Burnout Inventory. RESULTS: The sample consists of 135 community pharmacists. Twenty-three pharmacists reported significant post-traumatic stress symptoms (17%). High burnout symptoms were found in 33 (25%), 46 (34.9%) and 4 (3%) participants. Females scored higher than males for all questionnaires (P=0.01). CONCLUSIONS: This study is the first study which showed the psychological impact of COVID-19 in community pharmacists. Based on validated self-report questionnaires, up to 35% of pharmacists reported psychological disturbances. Interventions to promote psychological well-being of healthcare workers need to be developing.

Health-related quality of life in patients with a germline BRCA mutation and metastatic pancreatic cancer receiving maintenance olaparib.

BACKGROUND: Patients with metastatic pancreatic cancer often have a detriment in health-related quality of life (HRQoL). In the randomized, double-blind, phase III POLO trial progression-free survival was significantly longer with maintenance olaparib, a poly(ADP-ribose) polymerase inhibitor, than placebo in patients with a germline BRCA1 and/or BRCA2 mutation (gBRCAm) and metastatic pancreatic cancer whose disease had not progressed during first-line platinum-based chemotherapy. The prespecified HRQoL evaluation is reported here. PATIENTS AND METHODS: Patients were randomized to receive maintenance olaparib (300 mg b.i.d.; tablets) or placebo. HRQoL was assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30-item module at baseline, every 4 weeks until disease progression, at discontinuation, and 30 days after last dose. Scores ranged from 0 to 100; a ≥10-point change or difference between arms was considered clinically meaningful. Adjusted mean change from baseline was analysed using a mixed model for repeated measures. Time to sustained clinically meaningful deterioration (TSCMD) was analysed using a log-rank test. RESULTS: Of 154 randomized patients, 89 of 92 olaparib-arm and 58 of 62 placebo-arm patients were included in HRQoL analyses. The adjusted mean change in Global Health Status (GHS) score from baseline was <10 points in both arms and there was no significant between-group difference [-2.47; 95% confidence interval (CI) -7.27, 2.33; P = 0.31]. Analysis of physical functioning scores showed a significant between-group difference (-4.45 points; 95% CI -8.75, -0.16; P = 0.04). There was no difference in TSCMD for olaparib versus placebo for GHS [P = 0.25; hazard ratio (HR) 0.72; 95% CI 0.41, 1.27] or physical functioning (P = 0.32; HR 1.38; 95% CI 0.73, 2.63). CONCLUSIONS: HRQoL was preserved with maintenance olaparib treatment with no clinically meaningful difference compared with placebo. These results support the observed efficacy benefit of maintenance olaparib in patients with a gBRCAm and metastatic pancreatic cancer. CLINCALTRIALS.GOV NUMBER: NCT02184195.

Insulin-like growth factor 1 receptor activation promotes mammary gland tumor development by increasing glycolysis and promoting biomass production.

BACKGROUND: The insulin-like growth factor 1 (IGF1) signaling axis plays a major role in tumorigenesis. In a previous experiment, we chronically treated mice with several agonists of the IGF1 receptor (IGF1R). We found that chronic treatment with insulin analogues with high affinity towards the IGF1R (IGF1 and X10) decreased the mammary gland tumor latency time in a p53R270H/+WAPCre mouse model. Frequent injections with insulin analogues that only mildly activated the IGF1R in vivo (glargine and insulin) did not significantly decrease the tumor latency time in this mouse model. METHODS: Here, we performed next-generation RNA sequencing (40 million, 100 bp reads) on 50 mammary gland tumors to unravel the underlying mechanisms of IGF1R-promoted tumorigenesis. Mutational profiling of the individual tumors was performed to screen for treatment-specific mutations. The transcriptomic data were used to construct a support vector machine (SVM) classifier so that the phenotypic characteristics of tumors exposed to the different insulin analogue treatments could be predicted. For translational purposes, we ran the same classifiers on transcriptomic (micro-array) data of insulin analogue-exposed human breast cancer cell lines. Genome-scale metabolic modeling was performed with iMAT. RESULTS: We found that chronic X10 and IGF1 treatment resulted in tumors with an increased and sustained proliferative and invasive transcriptomic profile. Furthermore, a Warburg-like effect with increased glycolysis was observed in tumors of the X10/IGF1 groups and, to a lesser extent, also in glargine-induced tumors. A metabolic flux analysis revealed that this enhanced glycolysis programming in X10/IGF1 tumors was associated with increased biomass production programs. Although none of the treatments induced genetic instability or enhanced mutagenesis, mutations in Ezh2 and Hras were enriched in X10/IGF1 treatment tumors. CONCLUSIONS: Overall, these data suggest that the decreased mammary gland tumor latency time caused by chronic IGF1R activation is related to modulation of tumor progression rather than increased tumor initiation.

Bee Venom Phospholipase A2, a Novel Foxp3+ Regulatory T Cell Inducer, Protects Dopaminergic Neurons by Modulating Neuroinflammatory Responses in a Mouse Model of Parkinson's Disease.

Foxp3-expressing CD4(+) regulatory T cells (Tregs) are vital for maintaining immune tolerance in animal models of various immune diseases. In the present study, we demonstrated that bee venom phospholipase A2 (bvPLA2) is the major BV compound capable of inducing Treg expansion and promotes the survival of dopaminergic neurons in the 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine mouse model of Parkinson's disease. We associated this neuroprotective effect of bvPLA2 with microglial deactivation and reduction of CD4(+) T cell infiltration. Interestingly, bvPLA2 had no effect on mice depleted of Tregs by injecting anti-CD25 Ab. This finding indicated that Treg-mediated modulation of peripheral immune tolerance is strongly involved in the neuroprotective effects of bvPLA2. Furthermore, our results showed that bvPLA2 directly bound to CD206 on dendritic cells and consequently promoted the secretion of PGE2, which resulted in Treg differentiation via PGE2 (EP2) receptor signaling in Foxp3(-)CD4(+) T cells. These observations suggest that bvPLA2-CD206-PGE2-EP2 signaling promotes immune tolerance through Treg differentiation and contributes to the prevention of various neurodegenerative diseases, including Parkinson's disease.

An efficient orange-red-emitting LiNa3 P2 O7 :Sm3+ pyrophosphate: Structural and optical analysis for solid-state lighting.

A trivalent rare-earth ion (Sm3+ )-doped LiNa3 P2 O7 (LNPO) phosphor was synthesized using a conventional high-temperature solid-state reaction route. A predominant orthorhombic phase of LNPO was observed in all X-ray diffraction patterns. The surface states of the LNPO:Sm phosphor were confirmed by X-ray photoelectron spectroscopy. Under 401 nm excitation, the Sm-doped LNPO phosphors showed sharp emission peaks at 563, 600 and 647 nm that are related to the f-f transition of Sm3+ ions. The optimum concentration of Sm3+ (9 mol%) produced Commission Internationale de l'Eclairage chromaticity coordinates, color rendering index and correlated color temperature of (0.564, 0.434), 42 and 1843 K, respectively.

Release and toxicity comparison between industrial- and sunscreen-derived nano-ZnO particles.

Many consumer products containing ZnO have raised concern for safety in regard to environmental impact and the public health. Widely used sunscreens for protecting against UV and avoiding sunburns represent a great exposure to nano-ZnO, one of the ingredients commonly applied in sunscreens. Applying nanoproducts on beaches may release nanoparticles unintentionally into the ocean. Despite the accumulation of such nanoproducts in the ocean harming or being detrimental to critical marine organisms, few studies have investigated the release and potential toxicity of nanoparticles extracted from products and compared them with those from industrial-type nanoparticles. Results show that the cytotoxicity of both industrial- and sunscreen-derived nano-ZnO to the marine diatom algae, Thalassiosira pseudonana, increased as exposure increases over time, as measured by growth inhibition (%) of the algae at a constant concentration of nano-ZnO (10 mg/L). The extent of toxicity appeared to be higher from industrial-type nano-ZnO compared with sunscreen-extracted nano-ZnO, though the extent becomes similar when concentrations increase to 50 mg/L. On the other hand, at a fixed exposure time of 48 h, the cytotoxicity increases as concentrations increase with the higher toxicity shown from the industrial-type compared with sunscreen-induced nano-ZnO. Results indicate that while industrial-type nano-ZnO shows higher toxicity than sunscreen-derived nano-ZnO, the release and extent of toxicity from nano-ZnO extracted from sunscreen are not trivial and should be monitored for the development of safe manufacturing of nanomaterials-induced products.

Robust C-C bonded porous networks with chemically designed functionalities for improved CO2 capture from flue gas.

Effective carbon dioxide (CO2) capture requires solid, porous sorbents with chemically and thermally stable frameworks. Herein, we report two new carbon-carbon bonded porous networks that were synthesized through metal-free Knoevenagel nitrile-aldol condensation, namely the covalent organic polymer, COP-156 and 157. COP-156, due to high specific surface area (650 m2/g) and easily interchangeable nitrile groups, was modified post-synthetically into free amine- or amidoxime-containing networks. The modified COP-156-amine showed fast and increased CO2 uptake under simulated moist flue gas conditions compared to the starting network and usual industrial CO2 solvents, reaching up to 7.8 wt % uptake at 40 °C.

Effect of curing time on the physicochemical and sensory properties of beef jerky replaced salt with soy sauce, red pepper paste and soybean paste.

This study was done to investigate the quality properties of beef jerky with soy sauce, red pepper paste, and soybean paste replacing salt. Sliced beef samples were cured in salt (control), soy sauce, red pepper paste, and soybean paste for 24 or 48 h and then dried at 70°C for 8 h. Treatments showed higher final moisture content and lower Na(+) concentration than the control after drying for 8 h. The lightness and shear force values were lower in all treatment samples than in the control during 48 h of curing time. In particular, lower lipid oxidation was found in the jerky cured with red pepper paste than in the control. Sensory evaluation showed that color, flavor, and tenderness of jerky samples were improved by replacing salt with soy sauce, red pepper paste and soybean paste, and higher likeability scores of the beef jerky were obtained among those treatments after 48 h of curing time.

Darcy Forchhiemer imposed exponential heat source-sink and activation energy with the effects of bioconvection over radially stretching disc.

The Darcy-Forchheimer model is a commonly used and accurate method for simulating flow in porous media, proving beneficial for fluid separation, heat exchange, subsurface fluid transfer, filtration, and purification. The current study aims to describe heat and mass transfer in ternary nanofluid flow on a radially stretched sheet with activation energy. The velocity equation includes Darcy-Fochheimer porous media effects. The novelty of this study is enhanced by incorporating gyrotactic microorganisms which are versatile and in nanofluid can greatly improve the thermal conductivity and heat transfer properties of the base fluid, resulting in more efficient heat transfer systems. Furthermore, the governing PDEs are reduced to ODEs via appropriate similarity transformations. The influence of numerous parameters is expanded and physically depicted through the graphical illustration. As the Forchheimer number escalates, so do the medium's porosity and drag coefficient, resulting in more resistive forces and, as a result, lowering fluid velocity. It has been discovered that increasing the exponential heat source/sink causes convective flows that are deficient to transport heat away efficiently, resulting in a slower heat transfer rate. The concentration profile accumulates when the activation energy is large, resulting in a drop in the mass transfer rate. It is observed that the density of motile microorganisms increases with a rise in the Peclet number. Further, the results of the major engineering coefficients Skin-friction, Nusselt number, Sherwood number, and Microorganism density number are numerically examined and tabulated. Also, the numerical outcomes were found to be identical to the previous study.

Self-cleaning and mechanical properties of modified white cement with nanostructured TiO2.

In the present study, self-cleaning and mechanical properties of white Portland cement by addition of commercial available TiO2 nanoparticles with the average particle size of 80 nm were investigated. X-ray diffraction (XRD), transmission electron microscopy (TEM) and BET were used to characterize TiO2 nanoparticles. For determination of self-cleaning properties of TiO2-modified white cement, colorimetric tests in decolorization of C.I. Basic Red 46 (BR46) in comparison to unmodified cement samples was applied. The results indicated that with increasing the amount of TiO2 nanoparticles in modified cement, self-cleaning property of the samples increased. The mechanical properties of TiO2-modified and unmodified cement samples, such as time of setting of hydraulic cement, compressive strength of hydraulic cement mortar and flexural strength of hydraulic cement mortar were examined. The results indicated that addition of TiO2 nanoparticles up to maximum replacement level of 1.0% improved compressive and flexural strength and decreased its setting time.

Comparison of live performance and meat quality parameter of cross bred (korean native black pig and landrace) pigs with different coat colors.

Five hundred and forty crossbred (Korean native black pig×Landrace) F2 were selected at a commercial pig farm and then divided into six different coat color groups: (A: Black, B: White, C: Red, D: White spot in black, E: Black spot in white, F: Black spot in red). Birth weight, 21st d weight, 140th d weight and carcass weight varied among the different coat color groups. D group (white spot in black coat) showed a significantly higher body weight at each weigh (birth weight, 140th d weight and carcass weight) than did the other groups, whereas the C group (red coat color) showed a significantly lower body weight at finishing stage (140th d weight and carcass weight) compared to other groups. Meat quality characteristics, shear force, cooking loss and meat color were not significantly different among the different coat color groups, whereas drip loss was significantly higher in F than in other groups. Most blood characteristics were not significantly different among the different groups, except for the red blood cells.

Atomic-scale interpretation of the quantum oscillations in cuprate superconductors.

Cuprate superconductors display unusual features in bothkspace and real space as the superconductivity is suppressed-a broken Fermi surface, charge density wave, and pseudogap. Contrarily, recent transport measurements on cuprates under high magnetic fields report quantum oscillations (QOs), which imply rather a usual Fermi liquid behavior. To settle the disagreement, we investigated Bi2Sr2CaCu2O8+δunder a magnetic field in an atomic scale. A particle-hole (p-h) asymmetrically dispersing density of states (DOSs) modulation was found at the vortices on a slightly underdoped sample, while on a highly underdoped sample, no trace of the vortex was found even at 13 T. However, a similar p-h asymmetric DOS modulation persisted in almost an entire field of view. From this observation, we infer an alternative explanation of the QO results by providing a unifying picture where the aforementioned seemingly conflicting evidence from angle-resolved photoemission spectroscopy, spectroscopic imaging scanning tunneling microscopy, and magneto-transport measurements can be understood solely in terms of the DOS modulations.

HLA-A*33:25, a novel allele identified by sequence-based typing, is a well-documented allele in Koreans.

The new allele, HLA-A*33:25, differs from A*33:03:01 by one nucleotide substitution in exon 4 (c.778G>A) which results in an amino acid change at codon 236 [GCA→ACA (Ala>Thr)] in ß2-microglobulin-binding domain.

The correlation between amylin and insulin by treatment with 2-deoxy-D-glucose and/or mannose in rat insulinoma ins-1E cells.

Amylin or islet amyloid polypeptide (IAPP) is a peptide synthesized and secreted with insulin by the pancreatic ß-cells. A role for amylin in the pathogenesis of type 2 diabetes (T2D) by causing insulin resistance or inhibiting insulin synthesis and secretion has been suggested by in vitro and in vivo studies. These studies are consistent with the effect of endogenous amylin on pancreatic ßcells to modulate and/or restrain insulin secretion. Here, we reported the correlation between amylin and insulin in rat insulinoma INS-1E cells by treating 2-deoxy-D-glucose (2-DG) and/or mannose. Cell viability was not affected by 24 h treatment with 2-DG and/or mannose, but it was significantly decreased by 48 h treatment with 5 and 10 mM 2-DG. in the 24 h treatment, the synthesis of insulin in the cells and the secretion of insulin into the media showed a significant inverse association. in the 48-h treatment, amylin synthesis vs. the secretion and insulin synthesis vs. the secretion showed a significant inverse relation. The synthesis of amylin vs. insulin and the secretion of amylin vs. insulin showed a significant inverse relationship. The p-ERK, antioxidant enzymes (Cu/Zn-superoxide dismutase (SOD), Mn-SOD, and catalase), and endoplasmic reticulum (ER) stress markers (cleaved caspase-12, CHOP, p-SAPK/JNK, and BiP/GRP78) were significantly increased or decreased by the 24 h and 48 h treatments. These data suggest the relative correlation to the synthesis of amylin by cells vs. the secretion into the media, the synthesis of amylin vs. insulin, and the secretion of amylin vs. insulin under 2-DG and/or mannose in rat insulinoma INS-1E cells. Therefore, these results can provide primary data for the hypothesis that the amylin-insulin relationships may be involved with the human amylin toxicity in pancreatic beta cells.

A therapeutic intervention for Alzheimer's disease using ginsenoside Rg3: its role in M2 microglial activation and non-amyloidogenesis.

Previously, we have reported that ginsenoside Rg3 has typical activities for neuroprotection and Aß42 clearance by modulating microglia. In this study, we determined the pivotal role of ginsenoside Rg3 in microglia and neuronal cells. In human microglia, Rg3 and its stereoisomers significantly restored inflammatory M1 to normal M0 state and promoted M2 activation by up-regulating acute cytokines such as interleukin-10 and Arginase 1. Moreover, scavenger receptor type A (SRA) was significantly elevated in the presence of ginsenoside Rg3 and 20(S)-Rg3. This indicated that ginsenoside Rg3 could play a crucial role in Aß uptake and clearance under activated M2 state. We also observed that soluble amyloid precursor protein-alpha (sAPPα) and ADAM10 levels were increased in APP swe-transfected Nuro-2a neuronal cells, whereas sAPPß was not processed, suggesting that ginsenoside Rg3 was involved in non-amyloidogenic processing. In immunocytochemistry, SRA and a disintegrin and metalloproteinase 10 (desintegrin and metalloproteinase-containing protein 10, ADAM10) were coincidently upregulated in the presence of ginsenoside Rg3 and its stereoisomers compared to those in normal control. Taken together, these results suggested that ginsenoside Rg3 could boost acute activation of microglia, promote Aß uptake, and elevate the sAPPα processing under activated M2 state. Although in vivo studies need to be performed, it is certain that ginsenoside Rg3 is highly involved in ameliorating the pathogenesis of neurodegeneration and can be a promising candidate for treating Alzheimer's disease as a new therapeutic intervention.

Nanomolar melatonin influences insulin synthesis and secretion in rat insulinoma INS-1E cells.

Pancreatic beta-cell dysfunction results in reductions of insulin synthesis/secretion, cell survival, and insulin sensitivity thereby inducing diabetes mellitus. In this study, how nanomolar melatonin regulates insulin synthesis and secretion in rat insulinoma INS-1E cells was investigated. At melatonin concentrations of 10 - 100 nM for 48 hours, melatonin significantly increased the insulin protein level in INS-1E cells above the level in control cells without melatonin or glucose treatments and decreased the insulin level in media with glucose: increases in insulin synthesis and decreases in insulin secretion occurred in dose-dependent manners. Luzindole or 4-phenyl-2-propionamidotetralin (4P-PDOT), melatonin receptor antagonists, inhibited the melatonin-induced insulin level in cells and media. Levels of membrane vesicle trafficking-related proteins including Rab5, GOPC, phospho-caveolin-1, EEA1, and clathrin proteins significantly increased with melatonin treatment above that in control cells without melatonin or glucose treatments, whereas expressions of APPL1 and syntaxin-6 proteins significantly decreased with melatonin treatment. The increases in the phosphorylation of mammalian target of rapamycin (p-mTOR), raptor protein, and mTOR complex 1 (mTORC1) levels were consistent with the increments in the expressions of p-Akt (Ser473, Thr308) and stress-induced IRE1α/p-eIF2α proteins in the endoplasmic reticulum following melatonin treatment. also, expression levels of Bcl-2 and Bcl-xl proteins were significantly increased compared to those in control cells without melatonin or glucose treatments, whereas the Bax protein level decreased. These results indicate that nanomolar melatonin regulates insulin synthesis and secretion associated with membrane vesicle trafficking-related proteins, including Rab5, GOPC, p-Caveolin-1, EEA1, and clathrin, through the Akt/mTOR pathway.

Amyloid deposition in thymic extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue in a patient with myasthenia gravis: A case report.

Extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue (MALT) in the thymus is a rare disease. Furthermore, amyloid deposition in thymic MALT lymphoma has not been previously described. Here, we report a case of a 35-year-old man with thymic MALT lymphoma with amyloid deposition and myasthenia gravis. Chest computed tomography revealed an anterior mediastinal mass with internal cystic component and extensive calcification. Total thymectomy was performed and histopathologic findings were compatible with a diffuse amyloid deposition in extranodal marginal zone MALT lymphoma. The results indicate that thymic MALT lymphoma should be considered as a possible diagnosis in patients with a solid and cystic thymic mass and autoimmune disease, including myasthenia gravis.

Role of intestinal metaplasia subtyping in the risk of gastric cancer in Korea.

BACKGROUND AND AIM: Gastric cancer is believed to develop by a multistage process. Intestinal metaplasia (IM) is regarded as a premalignant condition; it is classified into subtypes I, II and III. The aim of this study was to evaluate whether the subtypes of IM were associated with progression to gastric cancer. METHODS: The study cohort consisted of 861 subjects, categorized as controls, gastric ulcers, dysplasia and cancer. The IM was scored histologically using the Sydney classification for the antrum and the body of the stomach. The biopsies were stained with high iron diamine and alcian blue (pH 2.5) (HID-AB2.5), and the IM was subtyped as I, II or III. RESULTS: The proportion of IM subtypes I, II and III were 14.5%, 47.2% and 38.3% in the antrum, and 28.1%, 57.8% and 14.1% in the body of the stomach, respectively. These distributions did not show significant differences depending on disease or Helicobacter pylori positivity. In cases that were H. pylori-positive, the prevalence of IM subtype II in the cancer and dysplasia groups was higher than in the control group in the body of the stomach (P < 0.05). The proportion of IM subtype III in the antrum increased in proportion with age (P = 0.036). CONCLUSIONS: IM subtyping was not found to play a major role in the prediction of gastric cancer development in Korea. IM subtype III was associated with aging, and IM subtype II appeared to be related to gastric carcinogenesis in the presence of H. pylori infection.

Properties of duck meat sausages supplemented with cereal flours.

Duck meat sausages were prepared using 10% beef fat (FDS) and 10% hydrated cereal flours including rice (RDS), wheat, corn, millet, and barley to replace fat. Control duck sausages (DS) were also prepared only with duck meat and duck meat plus 10% beef fat. Results showed that protein and fat contents significantly decreased and total expressible fluid reduced with the addition of cereal flours in duck sausage batters. The FDS had higher fat content and lower pH compared with others. Duck sausages with 10% supplemented wheat flour showed the lowest cooking loss among sausages and had similar redness and chroma values to FDS and DS. Texture analysis indicated that hardness of duck sausage significantly decreased when cereal flours and beef fat were added. In particular, RDS showed the lowest values for all texture measurements compared with others. Result of moisture absorption capacity suggested that the decrease in hardness in RDS was due to higher moisture retention for rice flour treatment. Sensory evaluation indicated that DS had significantly lower overall acceptability than RDS, due to its off-flavor, whereas RDS had higher overall acceptability than DS.
