AbstractDue to the rampant rise in obesity and diabetes, consumers are desperately seeking for ways to reduce their sugar intake, but to date there are no options that are both accessible and without sacrifice of palatability. One of the most promising new ingredients in the food system as a non-nutritive sugar substitute with near perfect palatability is D-psicose. D-psicose is currently produced using an in vitro enzymatic isomerization of D-fructose, resulting in low yield and purity, and therefore requiring substantial downstream processing to obtain a high purity product. This has made adoption of D-psicose into products limited and results in significantly higher per unit costs, reducing accessibility to those most in need. Here, we found that Escherichia coli natively possesses a thermodynamically favorable pathway to produce D-psicose from D-glucose through a series of phosphorylation-epimerization-dephosphorylation steps. To increase carbon flux towards D-psicose production, we introduced a series of genetic modifications to pathway enzymes, central carbon metabolism, and competing metabolic pathways. In an attempt to maximize both cellular viability and D-psicose production, we implemented methods for the dynamic regulation of key genes including clustered regularly interspaced short palindromic repeats inhibition (CRISPRi) and stationary-phase promoters. The engineered strains achieved complete consumption of D-glucose and production of D-psicose, at a titer of 15.3 g L-1, productivity of 2 g L-1 h-1, and yield of 62% under test tube conditions. These results demonstrate the viability of whole-cell catalysis as a sustainable alternative to in vitro enzymatic synthesis for the accessible production of D-psicose.

Published: October 2023

AbstractNutrient data obtained from field observations have the potential to enhance our understanding of oceanic biogeochemical cycling and productivity changes. In particular, long-term nutrient data can provide valuable information on the links between climate change and biogeochemical changes. However, unlike other observational variables such as sea surface temperature, nutrient data are limited in terms of their broad-scale observations and automated sensor-based measurements. In this study, we analyzed nitrate and phosphate data obtained from coastal regions in Northeast Asia and the northwest Pacific from 1980 to 2019 using the spatiotemporal kriging technique and provide results in a spatiotemporal grid format. The data are available at monthly intervals and may be attractive to researchers in the fields of oceanography, marine ecology, and marine biogeochemistry at the climate change scale. Furthermore, sharing the source code of the data production process can contribute to better long-term data reproduction in the future.
Biochemical data documenting variations in mucilage polysaccharides in a range of glycosyltransferase mutants

Published: October 2023

AbstractDuring Arabidopsis seed coat development, copious amounts of mucilage polysaccharides are produced in the epidermal cells. When hydrated on imbibition, these polysaccharides expand and are released to encapsulate the seed as a two-layered hydrogel. Polysaccharides are synthesized from UDP-sugars by glycosyltransferases (GTs) and several GTs, with differing activities, have been identified that contribute to mucilage polysaccharide synthesis. How these GTs orchestrate production of the complex polysaccharides found in mucilage remains to be determined. In this study, we generated a range of multiple GT mutants using either CRISPR/Cas9 targeted mutation or genetic crosses of existing T-DNA insertion mutants. Four traits for mucilage amounts or macromolecular properties were examined for four replicate seed lots from 31 different GT mutant combinations. This data provides a valuable resource for future genetic, biochemical, structural, and functional studies of the roles and properties of polysaccharides present in Arabidopsis mucilage and the relative contributions of different GTs to mucilage production.
Feelings of loneliness and meaning in life in subjects with Asperger’s syndrome: a pilot study

Published: October 2023

AbstractSubjects with Asperger’s syndrome without intellectual disabilities have significant difficulties in establishing social relationships despite their IQ being within the normal range. One of the effects of social deficit is depression. The question arises whether loneliness and dimensions of meaning in life correlate with the severity of depression and whether the average severity of depression, loneliness and dimensions of meaning in life differentiate the following groups: people with Asperger’s syndrome and depression, people with Asperger’s syndrome without depression, people with depression without Asperger’s syndrome and healthy subjects. The study was conducted on a total of 170 people, including: 43 people with Asperger’s syndrome and depression, 41 people with Asperger’s syndrome without depression, 40 people with depression without Asperger’s syndrome and 46 healthy people (without Asperger’s syndrome and without depression). All were administered a demographic survey, Beck Depression Inventory II (BDI-II), De Jong Gierveld Loneliness Scale, Life Attitude Profile-Revised. Asperger’s syndrome and depressive episodes were diagnosed on the basis of ICD-10 research criteria still applicable in Poland. In the group with Asperger’s syndrome and depression the highest levels of loneliness and the lowest values of the dimensions of the sense of meaning in life, except for the acceptance of death, were observed. This result was significantly different from the results obtained in the other study groups. Both in people with Asperger’s syndrome without depression and in people with depression without Asperger’s syndrome, the values of the dimensions of the sense of meaning in life and the level of loneliness differ significantly from the results obtained in the control group. The BDI-II scores correlated positively with the loneliness values and negatively with the sense of meaning in life values in all groups. The results indicate that both suffering from depression and having Asperger’s syndrome are associated with an increased sense of loneliness and a reduced sense of meaning in life. People with Asperger’s syndrome and depression have the highest values of loneliness and the lowest values of dimensions of the sense of meaning of life compared to the other groups studied. The limitation of the work is the deliberate selection of groups, because it would be interesting to answer the question whether Asperger’s syndrome is a risk factor for depression in the population.

AbstractResearch into the use of psilocybin for the treatment of psychiatric disorders is a growing field. Nevertheless, robust brain–behavior relationships linking psilocybin-induced brain changes to subjective drug-induced effects have not been established. Furthermore, it is unclear if the acute neural effects are dependent on individual heterogeneity in baseline characteristics. To address this, we assessed the effects of three oral doses of psilocybin vs. placebo on cerebral blood flow (CBF) using arterial spin labeling in healthy participants (N = 70; n = 31, 0.16 mg/kg; n = 10, 0.2 mg/kg; n = 29, 0.215 mg/kg). First, we quantified psilocybin-induced changes in relative and absolute CBF. Second, in an exploratory analysis, we assessed whether individual baseline characteristics and subjective psychedelic experience are associated with changes in CBF. Psychological and neurobiological baseline characteristics correlated with the psilocybin-induced reduction in relative CBF and the psilocybin-induced subjective experience. Furthermore, the psilocybin-induced subjective experience was associated with acute changes in relative and absolute CBF. The results demonstrated that inter-individual heterogeneity in the neural response to psilocybin is associated with baseline characteristics and shed light on the mechanisms underlying the psychedelic-induced altered state. Overall, these findings help guide the search for biomarkers, paving the way for a personalized medicine approach within the framework of psychedelic-assisted therapy.

AbstractWorldwide, salinity severely affects agricultural production of crops such as mung bean in arid and semi-arid regions. In saline conditions, various species of Rhizobium can be used to enhance nodulation and induce salinity tolerance in maize. The present study conducted a pot experiment to determine the efficiency of three rhizobial isolates under different salinity conditions, such as 1.41, 4 and 6 dS m−1, on mung bean growth parameters, antioxidant status and yield. Results revealed that salt stress imparted adverse effects on the growth, antioxidants, yield and nodulation of mung bean. Under high salt stress conditions, fresh weights were reduced for roots (78.24%), shoots (64.52%), pods (58.26%) and height (32.33%) as compared to un-inoculated control plants. However, an increase in proline content (46.14%) was observed in high salt stressed plants. Three Rhizobium isolates (Mg1, Mg2, and Mg3), on the other hand, mitigated the negative effects of salt stress after inoculation. However, effects of Mg3 inoculation were prominent at 6 dS m−1 and it enhanced the plant height (45.10%), fresh weight of shoot (58.68%), root (63.64%), pods fresh weight (34.10%), pods number per plant (92.04%), and grain nitrogen concentration (21%) than un-inoculated control. Rhizobium strains Mg1, and Mg2 expressed splendid results at 1.41 and 4 dS m−1 salinity stress. The growth promotion effects might be due to improvement in mineral uptake and ionic balance that minimized the inhibitory effects caused by salinity stress. Thus, inoculating with these strains may boost mung bean growth and yield under salinity stress.

AbstractThe current meta-analysis aims to investigate the existing articles that evaluated the implications of a positive family history of cancer on the risk of colorectal cancer (CRC) within the EMRO countries. We employed PubMed, Scopus, and Web of Science as search databases for this study. To assess the quality of the selected articles, we utilized the Newcastle–Ottawa (NCO) checklist. In comparing the impact of a family history of cancer between the case and control groups, we computed the odds ratio (OR) along with its corresponding 95% confidence interval (CI). Finally, 27 articles were selected for meta-analysis. The result of the meta-analysis showed a significant association between the presence of a family history of CRC or any cancers and CRC (OR 2.21; 95% CI 1.54–3.17; P < 0.001, OR 1.76; 95% CI 1.27–2.42; P = 0.001, respectively). Our findings underscore the critical importance of timely screening and early identification for individuals with a family history of cancer. By fostering close coordination among healthcare facilities and actively promoting the adoption of screening methods for early detection, we have the potential to significantly reduce both mortality rates and financial burdens of CRC on the general public, ultimately leading to enhanced patient outcomes.

Published: October 2023

AbstractNotch signaling determines cell fates in mouse intestine. Notch receptors contain multiple epidermal growth factor-like (EGF) repeats modified by O-glycans that regulate Notch signaling. Conditional deletion of protein O-fucosyltransferase 1 (Pofut1) substantially reduces Notch signaling and markedly perturbs lineage development in mouse intestine. However, mice with inactivated Pofut1 are viable, whereas complete elimination of Notch signaling in intestine is lethal. Here we investigate whether residual Notch signaling enabled by EGF-domain-specific O-linked N-acetylglucosamine transferase (Eogt) permits mice conditionally lacking Pofut1 in intestine to survive. Mice globally lacking Eogt alone were grossly unaffected in intestinal development. In contrast, mice lacking both Eogt and Pofut1 died at ~ 28 days after birth with greater loss of body weight, a greater increase in the number of goblet and Paneth cells, and greater downregulation of the Notch target gene Hes1, compared to Pofut1 deletion alone. These data reveal that both O-fucose and O-GlcNAc glycans are fundamental to Notch signaling in the intestine and provide new insights into roles for O-glycans in regulating Notch ligand binding. Finally, EOGT and O-GlcNAc glycans provide residual Notch signaling and support viability in mice lacking Pofut1 in the intestine.
The role and impact of alternative polyadenylation and miRNA regulation on the expression of the multidrug resistance-associated protein 1 (MRP-1/ABCC1) in epithelial ovarian cancer

AbstractThe ATP-binding cassette transporter (ABCC1) is associated with poor survival and chemotherapy drug resistance in high grade serous ovarian cancer (HGSOC). The mechanisms driving ABCC1 expression are poorly understood. Alternative polyadenylation (APA) can give rise to ABCC1 mRNAs which differ only in the length of their 3′untranslated regions (3′UTRs) in a process known as 3′UTR-APA. Like other ABC transporters, shortening of the 3′UTR of ABCC1 through 3′UTR-APA would eliminate microRNA binding sites found within the longer 3′UTRs, hence eliminating miRNA regulation and altering gene expression. We found that the HGSOC cell lines Caov-3 and Ovcar-3 express higher levels of ABCC1 protein than normal cells. APA of ABCC1 occurs in all three cell lines resulting in mRNAs with both short and long 3′UTRs. In Ovcar-3, mRNAs with shorter 3′UTRs dominate resulting in a six-fold increase in protein expression. We were able to show that miR-185-5p and miR-326 both target the ABCC1 3′UTR. Hence, 3′UTR-APA should be considered as an important regulator of ABCC1 expression in HGSOC. Both HGSOC cell lines are cisplatin resistant, and we used erastin to induce ferroptosis, an alternative form of cell death. We showed that we could induce ferroptosis and sensitize the cisplatin resistant cells to cisplatin by using erastin. Knocking down ABCC1 resulted in decreased cell viability, but did not contribute to erastin induced ferroptosis.

AbstractEarly identification of dengue patients at risk of adverse outcomes is important to prevent hospital overcrowding in low- to middle- income countries during epidemics. We performed a systematic review to identify which biomarkers measured in first 96 h of fever could predict dengue haemorrhagic fever (DHF, World Health Organization 1997 clinical classification) or severe dengue (SD, WHO 2009, clinical classification). PubMed, Scopus, CINAHL, Web of Science, and EMBASE databases were searched for prospective cohort and nested case–control studies published from 1997 to Feb 27, 2022. The protocol for the study was registered in PROSPERO (ID: CRD42021230053). After screening 6747 publications, and analysing 37 eligible studies reporting on 5925 patients, elevated C-reactive protein, aspartate aminotransferase, interleukin-8 and decreased albumin levels were strongly associated with dengue haemorrhagic fever (by meta-analyses of multiple studies, p < 0.05), while elevated vascular cell adhesion protein 1, syndecan-1, aspartate aminotransferase and C-reactive protein levels were strongly associated with severe dengue (by meta-analyses of multiple studies, p < 0.05). Further 44 and 28 biomarkers were associated with the risk of DHF and SD respectively, but only in a single study. The meta-analyses suggest the importance of early acute inflammation with hepatic involvement in determining the subsequent course of illness in dengue.

AbstractTemperature is an essential oceanographic variable (EOV) that still today remains coarsely resolved below the surface and near the seafloor. Here, we gather evidence to confirm that Distributed Acoustic Sensing (DAS) technology can convert tens of kilometer-long seafloor fiber-optic telecommunication cables into dense arrays of temperature anomaly sensors having millikelvin (mK) sensitivity, thus allowing to monitor oceanic processes such as internal waves and upwelling with unprecedented detail. Notably, we report high-resolution observations of highly coherent near-inertial and super-inertial internal waves in the NW Mediterranean sea, offshore of Toulon, France, having spatial extents of a few kilometers and producing maximum thermal anomalies of more than 5 K at maximum absolute rates of more than 1 K/h. We validate our observations with in-situ oceanographic sensors and an alternative optical fiber sensing technology. Currently, DAS only provides temperature changes estimates, however practical solutions are outlined to obtain continuous absolute temperature measurements with DAS at the seafloor. Our observations grant key advantages to DAS over established temperature sensors, showing its transformative potential for the description of seafloor temperature fluctuations over an extended range of spatial and temporal scales, as well as for the understanding of the evolution of the ocean in a broad sense (e.g. physical and ecological). Diverse ocean-oriented fields could benefit from the potential applications of this fast-developing technology.

AbstractThe measurement of hypertensive patients’ stroke knowledge is an important stroke prevention indicator of health care service quality. The aim of this study was to develop a Chinese version of the Stroke Knowledge Test and examine its psychometric properties, reliability, and validity for hypertensive patients. A sample of 200 hypertensive patients completed the Chinese version of the Stroke Knowledge Test, and 30 of the participants were retested after 2 weeks. The final Chinese version of the Stroke Knowledge Test included 20 items with acceptable content validity (I-CVI = 0.88 ~ 1.00, S-CVI/Ave = 0.97). These items showed satisfactory internal reliability consistency (Kuder Richardson-20 = 0.62) and test–retest reliability was 0.77. The 40% of the difficulty index was in the acceptable range, and 25% was in the difficult range, as well as the 90% items overall values for discrimination were ranged from 0.2 to > 0.4. Known-group validity testing was performed based on the education level, and the result exhibited significant difference (F = 21.21, p < 0.001). The Chinese version of the Stroke Knowledge Test demonstrated acceptable psychometric properties, thus providing a new tool for the future care of hypertensive patients in Taiwan. It also could be as a reference for healthcare providers to educate hypertensive patients on stroke prevention.
FUT1 variants responsible for Bombay or para-Bombay phenotypes in a database
Authors: Soejima Mikiko , Koda Yoshiro 
Published: October 2023

AbstractRare individuals with Bombay and para-Bombay phenotypes lack or have weak expression of the ABO(H) antigens on surface of red blood cells due to no or very weak H-type α(1,2)fucosyltransferase activity encoded byFUT1.These phenotypes are clinically important because subjects with these phenotypes can only accept transfusions of autologous blood or blood from subjects with the same phenotypes due to the anti-H antibody. To surveyFUT1alleles involved in Bombay and para-Bombay phenotypes, the effect of 22 uncharacterized nonsynonymous SNPs in the Erythrogene database on the α(1,2)fucosyltransferase activity were examined by transient expression studies and in silico analysis using four different online software tools. Two nonfunctional alleles (FUT1with c.503C>G and c.749G>C) and one weakly functional allele (with c.799T>C) were identified in transient expression studies, while the software predicted that the proteins encoded by more alleles including these would be impaired. Because both nonfunctionalFUT1alleles appear to link to the nonsecretor alleles, homozygotes of these alleles would be of the Bombay phenotype. The present results suggest that functional assays are useful for characterization of nonsynonymous SNPs ofFUT1when their phenotypes are not available.
