Abstract The functional properties of wheat gluten protein isolated from nonfermented dough stored at -6 °C, -12 °C, -18 °C, -24 °C and -30 °C for 10 d, 20 d and 30 d were investigated. The solubility and water holding capacity of gluten protein decreased with decreasing frozen storage temperatures and increasing frozen storage time. The foamability of gluten protein was not affected by different frozen storage temperatures. However, the foamability of gluten protein decreased with extension of the frozen storage time. The storage modulus (G') and loss modulus (G") of gluten decreased with decreasing frozen storage temperatures. Meanwhile, the storage modulus (G') and loss modulus (G") of gluten increased with extension of the frozen storage time. When the frozen storage temperature of gluten was -12°C, the frozen water content was lower than that in gluten with other frozen storage temperatures. The water migration of gluten protein under different frozen storage temperatures and times was measured by low-field NMR. The microstructure of gluten protein was also observed under a scanning electron microscope. It was found that more serious damage to the gluten structure occurred with lower freezing temperatures and longer freezing times.

Abstract The aim of this work was to study the effect of zinc (Zn) gluconate-resistant potato starch type 2 (RS2) systems on hydration and rheological properties of wheat flour dough. Wheat flour, Zn with a content from 0.16 mg% to 0.32 mg% (flour basis), and enriched RS2 at levels of 10 g% to 30 g% (flour basis) were used. Hydration, rheological properties and microstructural characteristics of wheat flour dough were analyzed. The results showed that the dough stability time decreased with increasing RS2. When the RS2 content was less than 25 g%, the stability time was significantly higher than that of the control group. RS2 and Zn could improve the tensile strength and thermal stability of the dough but reduced the quality of protein and mechanical resistance of the dough. Zn could increase the hardness, adhesiveness and springiness of the dough, while RS2 had a negative effect on the springiness of the dough. The RS2-Zn system reduced the water absorption, moisture content and molecular mobility of the dough, and damaged the microstructure of the dough to varying degrees. The addition of RS2 (10 g%) and Zn (0.24 mg%) could render a dough with satisfactory rheological properties, hydration and microstructural characteristics.

Abstract Using Bainong 365 wheat starch as raw material, starch samples were preheated in a RVA to simulate DSC heating profiles. The thermodynamic properties, long-range orderliness, short-range orderliness, and structure of wheat starch were determined by DSC, XRD, FTIR, LF-NMR and SEM to explore the phase transformation mechanism of Bainong 365 wheat starch at different water contents. The results show that at different moisture contents, when the endothermic transition temperature of starch samples determined by DSC was reached or exceeded, the enthalpy of starch was 0, all free water was converted into uneasy flowing water and bound water, and the surface structure of starch was severely damaged. At this time, starch was completely gelatinized, but the short-range and long-range ordered structures of starch determined by FTIR and XRD still existed and gradually decreased with increasing temperature. Therefore, it was concluded that the temperature range of the starch endothermic transition does not represent the temperature range of complete gelation of starch, and the structure destroyed by complete gelation of starch may not be simple short-range and long-range ordered molecular structures.

Abstract This paper took fermented dough as the research object. The difference between the subfreezing temperature and other freezing temperatures for long-term storage of fermented dough was discussed. The fermented dough was quick-frozen at -30 °C for 1 h and then stored at -6 °C, -12 °C and -18 °C for 5 d, 10 d and 15 d. The results indicated that with decreasing freezing temperature, the content of bound water in the dough increased gradually so that the water in the dough could be better preserved and the storage time of the dough could be prolonged. Although low temperatures could have a better storage effect, too low temperature and prolonged freezing time would destroy the structure of the starch in the dough. The structure of the starch stored at the subfreezing temperature (-12 °C) was better than that stored at other temperatures. Compared with the common freezing temperature (-18 °C), the subfreezing temperature not only achieves a better storage effect but also reduces energy consumption.

Abstract In the present study, the effects of heat-moisture treatment (HMT) on the structural properties, physicochemical properties and in vitro digestibility of sweet potato flour were investigated. Moisture mass fractions of samples were set as 20%, 25%, 30% or 35%, and treated at 110 °C for 4 h. Gelatinization characteristics, short-range order, double helix structure, crystallinity and digestive characteristics were studied by test of pasting and thermal, analysis of X-ray diffraction spectra, infrared spectra and in vitro digestion test. The results showed that the structural characteristics of the sweet potato flour with different moisture concentrations were quite different. The viscosity, breakdown value and setback value of HMT-sweet potato flour were all lower than those of the original flour. The content of rapidly digestible starch (RDS) decreased, while the contents of slowly digestible starch (SDS) and resistant starch (RS) increased after HMT. The results showed that HMT-25 had good cold and heat stability, low pasting viscosity and high contents of SDS and RS.

Abstract To observe the influence of thalidomide on tumor necrosis factor-a (TNF-α) of spontaneous type-2 diabetes rat (kk-Ay rat) model, and to explore the clinical value of TNF-a mediated inflammation approach to improve the injury on epithelial cell of kidney tubules. There are 30 kk-Ay rates being chosen to establish the Diabetic Nephropathy model and divided into thalidomide group and the model control group, 15 pieces for each group respectively. The levels of TNF-α, IL-1β, interleukin -6 (IL-6) and interleukin -18 (IL-18) of kk-Ay in the thalidomide group and the model control group were both at a higher level before treatment, but the difference was not statistically significant (P >0.05); The levels of TNF-α, IL-1β, interleukin -6 (IL-6) and interleukin -18 (IL-18) in kk-Ay rats 8/10/12 weeks after the treatment in the thalidomide group were significantly decreased, with statistically significant differences compared with the model control group (P < 0.05). The histopathological changes of kidney tubules epithelial cell injury on rats were observed through dissection. Thalidomide will effectively lower TNF-α and IL-1β expression levels in kk-Ay rat models, reduce inflammatory response, and thus improve damage on kidney tubules epithelial cell, which is worthy of further exploration and application.

Abstract In this paper, frozen steamed bread was used as the object to study the effect of frozen storage on the protein characteristics in a steamed bread system by measuring the changes in water holding capacity, oil holding capacity, emulsifying capacity, soluble protein content, surface hydrophobicity, secondary structure and molecular weights of gluten proteins in frozen steamed bread. The results showed that with an extension of frozen storage time, the disulfide bond (S‒S) and total content of sulfydryl (-SH) decreased as a whole, and the molecular weights of steamed bread proteins were mainly distributed between 22 and 31 kDa, which were composed of a mixture of gliadin and low-molecular-weight glutenin subunits. With a decrease in frozen storage temperature, the soluble protein contents and protein water holding capacities of steamed bread first increased and then decreased, and the trend of the surface hydrophobicity was opposite. The frozen storage temperature had a significant effect on the protein properties of the steamed bread system. The changes in protein emulsification, oil holding capacity and soluble protein content were stable at -24 °C, which was suitable for long-term frozen storage.

SUMMARY OBJECTIVE: To investigate the associations of high-mobility group box 1 and its specific receptor, receptor for advanced glycation end products with acute lung injury in patients with acute aortic dissection. METHODS: A total of 96 acute aortic dissection patients were divided into acute aortic dissection with acute lung injury group (38 cases) and acute aortic dissection without acute lung injury group (58 cases), according to partial pressure of oxygen/fraction of inspired oxygen. In addition, 44 healthy individuals were selected for the control group. The blood samples were taken. The serum high-mobility group box 1 and receptor for advanced glycation end products levels were detected by enzyme-linked immunosorbent assay, and the partial pressure of oxygen/fraction of inspired oxygen was measured. RESULTS: 24 h after admission, the high-mobility group box 1 and receptor for advanced glycation end products levels in acute aortic dissection with acute lung injury and acute aortic dissection without acute lung injury groups were significantly higher than those in the control group, respectively (p<0.05), and each index in acute aortic dissection with acute lung injury group was significantly higher than that in acute aortic dissection without acute lung injury group (p<0.05). At each time point within 96 h after admission, compared with acute aortic dissection without acute lung injury group, in acute aortic dissection with acute lung injury group, the high-mobility group box 1 and receptor for advanced glycation end products levels were increased, respectively, and the partial pressure of oxygen/fraction of inspired oxygen was decreased. The correlation analysis showed that, in acute aortic dissection patients, the high-mobility group box 1 and receptor for advanced glycation end products levels were negatively correlated with partial pressure of oxygen/fraction of inspired oxygen, respectively (p<0.05). CONCLUSIONS: The serum high-mobility group box 1 and receptor for advanced glycation end products levels may be associated with the occurrence of acute lung injury in acute aortic dissection patients. Monitoring the high-mobility group box 1 and receptor for advanced glycation end products levels can evaluate the risk of acute aortic dissection with acute lung injury.

ABSTRACT CONTEXT: Inflammatory myofibroblastic tumors are a rare type of soft-tissue tumor. Inflammatory myofibroblastic tumors are characterized by rearrangements involving the anaplastic lymphoma kinase gene locus on 2p23. Case Report: We report the case of a 67-year-old Chinese male who presented with dysuria and fever. Magnetic resonance imaging showed an irregular prostatic mass with an isointense signal and obscure boundary. Histopathological evaluation showed that the mass consisted mainly of spindle-shaped cells. Immunohistochemical evaluation showed that the tumor cells were negative for anaplastic lymphoma kinase. CONCLUSIONS: Inflammatory myofibroblastic prostate tumors are rare lesions with unclear etiology. The pathological diagnosis is very important.

Background: Hepatocellular carcinoma (HCC) has a high morbidity and mortality. Single nucleotide polymorphisms (SNPs) of microRNA (miRNA) may be associated with the susceptibility to develop certain malignant tumors. Aim: To study the association between SNPs of miRNA and hepatocellular carcinoma in peripheral blood samples. Material and Methods: Three SNPs in miRNA were studied in peripheral blood samples of 498 patients with HCC and 520 controls. Results: A significant association was observed between rs13299349 in miRNA3152 and HCC. AA genotype or A allele were significantly associated with increased risk of HCC. A allele was associated with the size and number of tumor foci. There was also a relationship between rs10061133 in miRNA449b and HCC. The G allele was significantly associated with increased risk of HCC compared with A allele. Conclusions: This study links rs13299349 in miRNA3152 and rs10061133 in miRNA449b with the risk of developing HCC.

The aim of this study was to establish whether the use of an extramedullary or intramedullary tibial cutting guide leads to superior mechanical leg axis and implant positioning. A meta-analysis of six randomized controlled trials including 350 knees was performed. For the mechanical axis, frontal tibial component angle and tibial slope, there were no significant differences in the mean values or the number of outliers (±3°) between the extramedullary and intramedullary groups. A reduced tourniquet time was associated with the intramedullary guide. No significant difference in the complication rate was noted between the two groups. Neither extramedullary nor intramedullary tibial alignment was more accurate in facilitating the tibial cut. Use of an intramedullary guide results in a shorter tourniquet time and exhibits a similar complication rate as the extramedullary guide.

OBJECTIVE: To determine the associations of liver lobe-based magnetic resonance diffusion-weighted imaging findings using multiple b values with the presence and Child-Pugh class of cirrhosis in patients with hepatitis B. METHODS: Seventy-four cirrhotic patients with hepatitis B and 25 healthy volunteers underwent diffusion-weighted imaging using b values of 0, 500, 800 and 1000 sec/mm2. The apparent diffusion coefficients of individual liver lobes for b(0,500), b(0,800) and b(0,1000) were derived from the signal intensity averaged across images obtained using b values of 0 and 500 sec/mm2, 0 and 800 sec/mm2, or 0 and 1000 sec/mm2, respectively, and were statistically analyzed to evaluate cirrhosis. RESULTS: The apparent diffusion coefficients for b(0,500), b(0,800) and b(0,1000) inversely correlated with the Child-Pugh class in the left lateral liver lobe, the left medial liver lobe, the right liver lobe and the caudate lobe (r=-0.35 to -0.60, all p<0.05), except for the apparent diffusion coefficient for b(0,1000) in the left medial liver lobe (r=-0.17, p>0.05). Among these parameters, the apparent diffusion coefficient for b(0,500) in the left lateral liver lobe best differentiated normal from cirrhotic liver, with an area under the receiver operating characteristic curve of 0.989. The apparent diffusion coefficient for b(0,800) in the right liver lobe best distinguished Child-Pugh class A from B-C and A-B from C, with areas under the receiver operating characteristic curve of 0.732 and 0.747, respectively. CONCLUSION: Liver lobe-based apparent diffusion coefficients for b(0,500) and b(0,800) appear to be associated with the presence and Child-Pugh class of liver cirrhosis.

OBJECTIVES: To investigate the prevalence, extent, severity, and features of coronary artery lesions in stable patients with multiple cardiovascular risk factors. METHODS: Seventy-seven patients with more than 3 cardiovascular risk factors were suspected of having coronary artery disease. Patients with high-risk factors and 39 controls with no risk factors were enrolled in the study. The related risk factors included hypertension, impaired glucose tolerance, dyslipidemia, smoking history, and overweight. The characteristics of coronary lesions were identified and evaluated by 64-slice coronary computed tomography angiography. RESULTS: The incidence of coronary atherosclerosis was higher in the high-risk group than in the no-risk group. The involved branches of the coronary artery, the diffusivity of the lesion, the degree of stenosis, and the nature of the plaques were significantly more severe in the high-risk group compared with the no-risk group (all p < 0.05). CONCLUSION: Among stable individuals with high-risk factors, early coronary artery lesions are common and severe. Computed tomography has promising value for the early screening of coronary lesions.
