Opening of stomata in plants with crassulacean acid metabolism (CAM) is mainly shifted to the night period when atmospheric CO2 is fixed by phosphoenolpyruvate carboxylase and stored as malic acid in the vacuole. As such, CAM plants ameliorate transpirational water losses and display substantially higher water-use efficiency compared with C3 and C4 plants. In the past decade significant technical advances have allowed an unprecedented exploration of genomes, transcriptomes, proteomes and metabolomes of CAM plants and efforts are ongoing to engineer the CAM pathway in C3 plants. Whilst research efforts have traditionally focused on nocturnal carboxylation, less information is known regarding the drivers behind diurnal malate remobilisation from the vacuole that liberates CO2 to be fixed by RuBisCo behind closed stomata. To shed more light on this process, we provide a stoichiometric analysis to identify potentially rate-limiting steps underpinning diurnal malate mobilisation and help direct future research efforts. Within this remit we address three key questions Q1 Does light-dependent assimilation of CO2 via RuBisCo dictate the rate of malate mobilisation? Q2 Do the enzymes responsible for malate decarboxylation limit daytime mobilisation from the vacuole? Q3 Does malate efflux from the vacuole set the pace of decarboxylation?
Water-soluble cellulose acetate (WSCA), a synthetic fiber source, was applied to human stool cultures and to pure cultures of representative Bacteroides species to characterize the fermentation properties of WSCA in the human gut, and to assess the potential availability of WSCA as a food or additive candidate.
All nine of the different types of WSCA tested here provided increased acetate levels in human stool cultures. Greater levels of deacetylation were observed as the degree of substitution of hydroxyl groups by acetyl groups decreased. Among the nine tested types of WSCA, CA-0.78-128 caused the largest shifts of the microbial community, including an increased abundance of members of the genus Bacteroides, especially Bacteroides uniformis. Of four representative human gut Bacteroides species, only B. uniformis grew in pure culture on WSCA to produce acetate actively.
Water-soluble cellulose acetate has the potential for dietary application in human and other monogastric animals, based on the enhanced production of short-chain fatty acids (SCFAs), in particular acetate, in the hindgut. Short-chain fatty acid production is caused by selective proliferation of specific gut bacteria belonging to the genus Bacteroides. © 2020 Society of Chemical Industry.

The purpose of this study was to develop and validate an individualized nomogram to predict venous thromboembolism (VTE) risk in hospitalized postoperative breast cancer patients.
A single-central retrospective and non-interventional trial.
For model development, we used data from 4,755 breast cancer patients between 1 November 2016-30 June 2018 (3,310 patients in the development group and 1,445 in the validation group). Overall, 216 patients developed VTE (150 in development group and 66 in validation group). The model was validated by receiver operating characteristic curves and the calibration plot. The clinical utility of the model was determined through decision curve analysis.
The individualized nomogram consisted of six clinical factors age, body mass index, number of cardiovascular comorbidities, neoadjuvant chemotherapy, surgical treatment, hospital length of stay and two pre-operative biomarkers of Homocysteine and D-dimer. The model at the 3.9% optimal cut-off had the area under the curve oxis in hospitalized postoperative breast cancer patients.
To investigate the role of abnormal cerebroplacental ratio (CPR) in predicting adverse fetal outcome in pregnancies with induction of labor.
This prospective observational study conducted at Medeniyet University Göztepe Training and Research Hospital between December 1, 2018 and October 31, 2019 enrolled women with scheduled induction of labor at or beyond 37weeks of pregnancy. Women with singleton non-anomalous fetuses with cephalic presentation and who had Bishop scores of 5 or less in pelvic examination were included in the study. Exclusion criteria were the presence of uterine scar history, non-cephalic presentation, multiple pregnancy, vacuum- or forceps-assisted delivery, and shoulder dystocia. Using fetal Doppler ultrasound, CPR was calculated (the ratio of umbilical artery to middle cerebral artery pulsatility index) and categorized into abnormal CPR (<1) and normal CPR (≥1). Data on maternal and delivery characteristics, fetal birth weight, and fetal complications were compared between the grodverse fetal outcome in singleton pregnancies with scheduled induction of labor.This study provides an evaluation of the use of rheology to characterize soft, semi-hard, and hard fats in relation to determine the crystallization onset, crystallization behavior, as well as microstructure development using either a plate-plate or a starch pasting cell (SPC). The results from this study demonstrate that when applying rheology to study fat crystallization, the results must be interpreted with care. The application of a plate-plate geometry allowed for sensitive evaluation of the initial nucleation phase, which was not possible with an SPC. Both geometries could provide information on crystallization behavior in terms of one-step or two-step crystallization. Bromelain order However, in the late stage of the crystallization process, when the fat crystals form a strong network, the SPC could not describe differences in the rheology of the fat-crystal network, which was a possibility by the use of a plate-plate geometry. Thus, oscillatory rheology with a suitable geometry can be used to evaluate the entire crystallization process.
