PLOS ONE , 2014, DOI: 10.1371/journal.pone.0093471
Abstract: Background Several prospective studies have been conducted to examine the relationship between fruit juice intake and risk of incident type 2 diabetes, but results have been mixed. In the present study, we aimed to estimate the association between fruit juice intake and risk of type 2 diabetes. Methods PubMed and Embase databases were searched up to December 2013. All prospective cohort studies of fruit juice intake with risk of type 2 diabetes were included. The pooled relative risks (RRs) with 95% confidence intervals (CIs) for highest vs. lowest category of fruit juice intake were estimated using a random-effects model. Results A total of four studies (191,686 participants, including 12,375 with type 2 diabetes) investigated the association between sugar-sweetened fruit juice and risk of incident type 2 diabetes, and four studies (137,663 participants and 4,906 cases) investigated the association between 100% fruit juice and risk of incident type 2 diabetes. A higher intake of sugar-sweetened fruit juice was significantly associated with risk of type 2 diabetes (RR = 1.28, 95%CI = 1.04–1.59, p = 0.02), while intake of 100% fruit juice was not associated with risk of developing type 2 diabetes (RR = 1.03, 95% CI = 0.91–1.18, p = 0.62). Conclusions Our findings support dietary recommendations to limit sugar-sweetened beverages, such as fruit juice with added sugar, to prevent the development of type 2 diabetes.

Characteristics and mechanisms of sorption of organic contaminants onto sodium dodecyl sulfate modified Ca-Al layered double hydroxides
XiuXiu Ruan,Peng Sun,XingXing Ouyang,GuangRen Qian
Chinese Science Bulletin , 2011, DOI: 10.1007/s11434-011-4762-y
Abstract: A series of calcium aluminum layered double hydroxides (LDHs) modified with sodium dodecyl sulfate (SDS) (Ca /Al-SDSLDHs) were synthesized by co-precipitation, and characterized by X-ray diffraction, Fourier transform infrared spectroscopy, and elemental analysis. The Ca /Al-SDS-LDHs enhanced sorption of nitrobenzene and naphthalene from water compared with inorganic LDH (Ca /Al-Cl-LDH). The sorption isotherms for sorption of organic contaminants onto the Ca /Al-SDS-LDHs were linear for the concentration range tested, which implies that the sorption mechanism is mainly by partition. The sorption of naphthalene onto Ca /Al-SDS-LDH was apparently stronger than that of nitrobenzene, but this order reversed after eliminating the hydrophobic effect of these two contaminants. Because naphthalene is non-polar and nitrobenzene is polar, the results indicate that the Ca /Al-SDS-LDHs were selective for polar organic contaminants.

Journal of Animal and Veterinary Advances , 2012, DOI: 10.3923/javaa.2012.4678.4683
Abstract: An experiment was conducted to investigate responses in milk production, milk composition and rumen fermentation of dairy cows receiving a corn straw or mixed forage diet. Ten primiparous and rumen-cannulated Holstein dairy cows averaging 127±13 days in milk (mean±SD) were randomly assigned to CS (37.1% corn straw as sole forage) or MF diet (3.7% Chinese wildrye+28.4% alfalfa hay+26.5% corn silage as mixed forage). Feed intake, body weight, body condition score and milk production were monitored. Milk fat, protein, lactose and total solids were analyzed by near-infrared analysis. Samples of rumen fluid were collected via cannula every 6 h over a 72 h duration to analyze pH, ammonia-N and VFA concentrations. Results showed that cows fed MF diet significantly increased dry matter intake (p<0.01) as well as yields of milk (p<0.05), 4% FCM (p<0.01), milk fat (p<0.05), lactose (p<0.05) and total solids (p<0.05). Cows fed MF diet had higher (p<0.01) ruminal acetate concentrate and ratio of acetate to propionate and lower concentrations of ammonia-N (p<0.01), propionate (p<0.05), butyrate (p<0.01), isobutyrate (p<0.01), valerate (p<0.01) and isovalerate (p<0.01) than cows fed CS diet. Collectively, these results suggest that cows fed MF diet improve DMI and milk production. In addition, cows fed CS diet had minor differences in rumen pH and total VFA concentration which may suggest that corn straw played an important role in maintaining rumen function when cows were fed this higher concentrate diet.

PLOS ONE , 2014, DOI: 10.1371/journal.pone.0087693
Abstract: Background As an important perennial herbaceous flower, Salvia splendens possesses high ornamental value. Understanding its branching processes may help scientists select the best plant type. Although Salvia splendens is a frequently-used horticultural flower, only limited transcriptomic or genomic research is available in public databases. In the present study, we, for the first time, constructed a comprehensive dataset for Salvia splendens through de novo high-throughput transcriptome sequencing. Methodology/Principal Findings We performed de novo transcriptome sequencing on two different branching type plants (Strain 35 and Cailinghong) using the Illumina paired-end sequencing technology. For Strain 35, a total of 16,488,829 reads were generated and assembled into 38,498 unigenes, with a mean length of approximately 779 bp. For Cailinghong, 16,464,713 reads were generated and assembled into 34,302 unigenes, with a mean length of approximately 812 bp. Moreover, a total of 49,310 unigenes for Salvia splendens were identified, among them 33,925 (68.80%) were annotated in the non-redundant NCBI database, 25,371 (51.45%) were annotated in the Swiss-Prot database, while 24,888 (50.47%) and 9,896 (20.07%) unigenes were assigned to gene ontology categories and clusters of orthologous groups, respectively. Using the Kyoto Encyclopedia of Genes and Genomes pathway database, we identified 134 differently expressed unigenes between Strain 35 and Cailinghong, and then these unigenes were mapped to 79 pathways. In addition, we detected 2,453 simple sequence repeats (SSRs). Conclusions We obtained a comprehensive transcriptomic information from this work and provided a valuable resource of transcript sequences of Salvia splendens in public databases. Moreover, some candidate genes potentially involved in branching were identified. Furthermore, numerous obtained SSRs might contribute to marker-assisted selection. These data could be further utilized in functional genomics studies on Salvia splendens.

Xuemeng Yin, Xinmin Yin
Open Journal of Stomatology (OJST) , 2014, DOI: 10.4236/ojst.2014.41001
Abstract:

Objective: To evaluate the effect of wireless biofeedback therapy on bruxism. Methods: Fifteen bruxiers participated to be treated by this therapy. The abnormal movements of teeth during sleep were monitored by a maxillary splint with an electric resistance strain gauge. Meanwhile, the receiver device recorded these details and analyzed the data, including the value of the biting force, occurring time and duration. If the value of biting force or duration exceeds the threshold, a vibrating device like a watch style will alert the patient to relax the masticatory muscles and nervous system to stop the abnormal grinding or clenching. Data were recorded during 8 hours’ sleep and analyzed after the 12 weeks’ treatment and 24 weeks’ treatment. Results: The average episodes of bruxism have declined from (10.60 ± 1.23) to (6.60 ± 0.75) after 12 weeks’ treatment (p < 0.05), and the average duration of bruxism events was reduced from (13.2 ± 0.74) s to (6.50 ± 0.40) s (p < 0.05). The average episodes of bruxism have declined to (3.80 ± 0.64) after 24 weeks’ treatment, and the average duration of bruxism events was reduced to (3.37 ± 0.34) s (p < 0.05). Conclusions: The results suggest that biofeedback therapy can be effective for bruxism treatment.

Yin Zhe
Open Journal of Genetics (OJGen) , 2012, DOI: 10.4236/ojgen.2012.21005
Abstract: In this paper, based on binomial formula, a law of genetic inheritance is proposed, and it would have certain reference value for future genetic inheritance research. Besides, a recursive algorithm for recessive inheritance is also proposed. Given any two of the male parent, female parent and filial generation, the genomic information of the third one can be calculated uniquely.
