Sourdough production: fermentation strategies, microbial ecology, and use of non-flour ingredients

Abstract Sourdough production is an ancient method to ferment flour from cereals for the manufacturing of baked goods. This review deals with the state-of-the-art of current fermentation strategies for sourdough production and the microbial ecology of mature sourdoughs, with a particular focus on the use of non-flour ingredients. Flour fermentation processes for sourdough production are typically carried out by heterogeneous communities of lactic acid bacteria and yeasts. Acetic acid bacteria may also occur, although their presence and role in sourdough production can be criticized. Based on the inoculum used, sourdough productions can be distinguished in fermentation processes using backslopping procedures, originating from a spontaneously fermented flour-water mixture (Type 1), starter culture-initiated fermentation processes (Type 2), and starter culture-initiated fermentation processes that are followed by backslopping (Type 3). In traditional recipes for the initiation and/or propagation of Type 1 sourdough productions, non-flour ingredients are often added to the flour-water mixture. These ingredients may be the source of an additional microbial inoculum and/or serve as (co-)substrates for fermentation. An example of the former is the addition of yoghurt; an example of the latter is the use of fruit juices. The survival of microorganisms transferred from the ingredients to the fermenting flour-water mixture depends on the competitiveness toward particular strains of the microbial species present under the harsh conditions of the sourdough ecosystem. Their survival and growth is also determined by the presence of the appropriate substrates, whether or not carried over by the ingredients added.
Is Kissing a Bellwether of Sexual and Relationship Satisfaction and Dissatisfaction?

Abstract In this study we explored how the amount of kissing during the most recent sexual experience (specific kissing) and amount of kissing during the last year (global kissing) were both associated with the quality of the sexual relationship and overall relationship satisfaction and dissatisfaction. To understand these associations, we obtained surveys from a national sample of 878 participants who had been in a romantic relationship for at least two years. We evaluated their results through a structural equation model and found that for women the rates of specific kissing were associated with their ability to orgasm, sexual frequency, and indirectly to sexual satisfaction. For both men and women, measures of global kissing were associated with both sexual and relationship satisfaction but more strongly with measures of sexual and relationship dissatisfaction. These findings suggest that measures of kissing could be used as a bellwether of both the quality of the sexual relationship for women and of feelings of dissatisfaction about both the sexual and overall relationship for both sexes.
A modified fluctuation assay reveals a natural mutator phenotype that drives mutation spectrum variation within Saccharomyces cerevisiae.

Although studies of Saccharomyces cerevisiae have provided many insights into mutagenesis and DNA repair, most of this work has focused on a few laboratory strains. Much less is known about the phenotypic effects of natural variation within S. cerevisiae's DNA repair pathways. Here, we use natural polymorphisms to detect historical mutation spectrum differences among several wild and domesticated S. cerevisiae strains. To determine whether these differences are likely caused by genetic mutation rate modifiers, we use a modified fluctuation assay with a CAN1 reporter to measure de novo mutation rates and spectra in 16 of the analyzed strains. We measure a 10-fold range of mutation rates and identify two strains with distinctive mutation spectra. These strains, known as AEQ and AAR, come from the panel's 'Mosaic beer' clade and share an enrichment for C>A mutations that is also observed in rare variation segregating throughout the genomes of several Mosaic beer and Mixed origin strains. Both AEQ and AAR are haploid derivatives of the diploid natural isolate CBS 1782, whose rare polymorphisms are enriched for C>A as well, suggesting that the underlying mutator allele is likely active in nature. We use a plasmid complementation test to show that AAR and AEQ share a mutator allele in the DNA repair gene OGG1, which excises 8-oxoguanine lesions that can cause C>A mutations if left unrepaired.
Neural Correlates of Anti-appetite Medications: An fMRI Meta-analysis

Food craving is a health issue for a considerable proportion of the general population. Medications have been introduced to alleviate the craving or reduce the appetite via a neuropharmacological approach. However, the underlying cerebral processing of the medications was largely unknown. This study aimed to meta-analyze existing neuroimaging findings. PubMed, Web of Science, and Scopus were searched to identify relevant publications. Original studies that reported brain imaging findings using functional magnetic resonance imaging (fMRI) were initially included. The reported coordinates of brain activation available from the studies were extracted and meta-analyzed with the activation likelihood estimation (ALE) approach via the software GingerALE. The overall analysis pooling data from 24 studies showed that the right claustrum and insula were the targeted sites of altered cerebral processing of food cues by the medications. Subgroup analysis pooling data from 11 studies showed that these sites had reduced activity levels under medications compared to placebo. The location of this significant cluster partially overlapped with that attributable to affective value processing of food cues in a prior meta-analysis. No brain regions were found to have increased activity levels by medications. These neural correlates may help explain the physiological effect of food consumption by anti-appetite and anti-obesity medications.
Examining the Role of National Context: Do Country Conditions During Childhood Impact Perpetration of Dating Violence in Emerging Adulthood?

The link between individual experiences in early childhood or adolescence years and future dating violence (DV) perpetration has been well established and explored across various populations. However, little is known on a worldwide scale, about the association between national conditions during childhood, like overall well-being or status of women in that nation, and perpetration of DV in emerging adulthood. Applying life-course theory and a socioecological framework to data from the International Dating Violence Study and country index scores, this study examines whether the overall well-being of a country during childhood affects the perpetration of DV in emerging adulthood. We also examine if the national status of women during childhood moderates the association between overall well-being of a country during childhood and DV perpetration in emerging adulthood, all while controlling for the individual effects of gender, violence approval, criminal history, neglect history, and anger management. The study’s sample size included 4,280 people from 19 countries. Men reported less likelihood of perpetrating DV compared to women. Cross national comparative analysis revealed a significant interaction effect between country well-being and women status on DV perpetration (β = 0.69, p < .05) at the national level. When women’s status was low or moderate, the well-being status showed an inverse effect on the probability of DV perpetration, but this direction switched in the face of high women’s status. Contrary to previous research, higher women status may contribute to increased intimate partner violence (IPV) perpetration. Our findings underscore the existence of context-specific social conditions in relationship to IPV. Broad implications of the findings, potential explanations and directions for future research are discussed.
Ventriculolumbar perfusion and inhalational anesthesia with sevoflurane in an accidental intrathecal injection of tranexamic acid: unreported treatment options

Background Tranexamic acid (TXA) decreases hemorrhage-related mortality in trauma patients and is increasingly being used during obstetric and orthopedic surgeries. Inadvertent intrathecal injection of TXA is a rare, potentially lethal event leading to dose-dependent cardiotoxicity and neurotoxicity. TXA enhances neuronal excitation by antagonizing inhibitory γ-aminobutyric acid type A and glycine receptors. Until now, mechanistic-based pharmacological treatments targeting multiple central nervous system receptors have been advocated for use in such cases, with no data on intrathecal TXA elimination techniques. Case presentation A patient scheduled for hip surgery accidentally received 350 mg of intrathecal TXA instead of levobupivacaine. The clinical picture progressed from spinal segmental myoclonus to generalized convulsions and malignant arrhythmias. The treatment consisted of ventriculolumbar perfusion with normal saline at a rate of 50 mL/hour starting 5 hours after TXA administration and inhalational sedation with sevoflurane, in addition to drugs acting on multiple receptors at different central nervous system levels. Over 2 months the neurological status improved, although it was not complete. Conclusions For the first time, the feasibility and possible clinical efficacy of combined treatment with ventriculolumbar perfusion and inhalational sedation with sevoflurane were demonstrated. A referral to a neurosurgical facility is recommended in patients with acute TXA-induced neurotoxicity and cardiotoxicity.
RNA‐binding proteins and RNA methylation in myeloid cells

RNA‐binding proteins (RBPs) regulate all aspects of the life of mRNA transcripts. They are critically important in regulating immune responses, most notably by restraining excessive inflammation that can potentially lead to tissue damage. RBPs are also crucial for pathogen sensing, for instance for the recognition of viral nucleic acids. Concordant with these central regulatory roles, the dysregulated activity of many RBPs can give rise to disease. The expression and function of RBPs are therefore highly controlled by an elaborate network of transcriptional, post‐transcriptional and post‐translational mechanisms, including the ability of different RBPs to cross‐regulate each other's expression. With an emphasis on macrophages and mast cells, we review current knowledge on the role of selected RBPs that have been shown to directly impact the expression of inflammatory transcripts. By focusing specifically on proteins of the Regnase and ZFP36 family, as well as on factors involved in N6‐methyladenosine (m6A) deposition and recognition, we discuss mechanism of action, regulatory feedback, and impact of these selected proteins on immune responses. Finally, we include examples of the role of m6A and RBPs in the recognition of viral RNAs. Overall, we provide a general overview of the impact of selected RBPs on the myeloid compartment, followed by a discussion of outstanding questions and challenges for the future.
Visual adaptation and retinal characterization of the Garganey (Anas querquedula): Histological and scanning electron microscope observations

The present study was designed to provide a complete morphological description of the eye of the migratory Garganey duck (Anas querquedula) and its visual adaptation with the different surrounding environmental conditions during its migration journeys using a stereomicroscope, scanning electron microscope (SEM), and light microscope. The current work depends on six adult Garganey ducks that were captured from the area near and on the shores of Edku city. The obtained results revealed that the eye of the migratory Garganey duck has the features of both diurnal and nocturnal birds. The histological examination reveals that the pigmented epithelium of the retina has long prolongations filled with melanin. The cone is the dominant photoreceptor, but simple rods are present. The inner nuclear and ganglion cell layers are thick. SEM examination shows that the arrangement of the collagen fibrils on the external surface was reticular in shape. The radial folds present as pledged structures on the pigmented epithelium covered with circular structures. The main lens body has flat with hexagonal outlines fibers. The edges and surfaces of these hexagonal fibers were studded with protrusions or elevations (balls) and depressions (sockets). The sockets and balls were either rounded or ellipsoid in shape. The balls were more on the edges and the sockets on the surface. In conclusion, our findings indicated a higher degree of functional adaptation between the morphological structure of the eye and the surrounding environmental conditions.
Soot Formation in Non-premixed Laminar Flames at Subcritical and Supercritical Pressures

Soot Formation in Non-Premixed Laminar Flames at Subcritical and Supercritical Pressures HYUN IL JOO Doctor of Philosophy Graduate Department of Aerospace Science and Engineering University of Toronto 2010 An experimental study was conducted using axisymmetric co-flow laminar diffusion flames of methane-air, methane-oxygen and ethylene-air to examine the effect of pressure on soot formation and the structure of the temperature field. A liquid fuel burner was designed and built to observe the sooting behavior of methanol-air and n-heptane-air laminar diffusion flames at elevated pressures up to 50 atm. A non-intrusive, line-of-sight spectral soot emission (SSE) diagnostic technique was used to determine the temperature and the soot volume fraction of methane-air flames up to 60 atm, methane-oxygen flames up to 90 atm and ethylene-air flames up to 35 atm. The physical flame structure of the methane-air and methane-oxygen diffusion flames were characterized over the pressure range of 10 to 100 atm and up to 35 atm for ethylene-air flames. The flame height, marked by the visible soot radiation emission, remained relatively constant for methaneair and ethylene-air flames over their respected pressure ranges, while the visible flame height for the methane-oxygen flames was reduced by over 50 % between 10 and 100 atm. During methane-air experiments, observations of anomalous occurrence of liquid material formation at 60 atm and above were recorded. The maximum conversion of the carbon in the fuel to soot exhibited a strong power-law dependence on pressure. At pressures 10 to 30 atm, the pressure exponent is approximately 0.73 for methane-air flames. At higher pressures, between 30 and 60 atm, the pressure exponent is approximately 0.33. The maximum fuel carbon conversion to soot is 12.6 % at 60 atm. For methane-oxygen
Dynamic alterations of H3K4me3 and H3K27me3 at ADAM17 and Jagged‐1 gene promoters cause an inflammatory switch of endothelial cells

Histone protein modifications control the inflammatory state of many immune cells. However, how dynamic alteration in histone methylation causes endothelial inflammation and apoptosis is not clearly understood. To examine this, we explored two contrasting histone methylations; an activating histone H3 lysine 4 trimethylation (H3K4me3) and a repressive histone H3 lysine 27 trimethylation (H3K27me3) in endothelial cells (EC) undergoing inflammation. Through computer‐aided reconstruction and 3D printing of the human coronary artery, we developed a unique model where EC were exposed to a pattern of oscillatory/disturbed flow as similar to in vivo conditions. Upon induction of endothelial inflammation, we detected a significant rise in H3K4me3 caused by an increase in the expression of SET1/COMPASS family of H3K4 methyltransferases, including MLL1, MLL2, and SET1B. In contrast, EC undergoing inflammation exhibited truncated H3K27me3 level engendered by EZH2 cytosolic translocation through threonine 367 phosphorylation and an increase in the expression of histone demethylating enzyme JMJD3 and UTX. Additionally, many SET1/COMPASS family of proteins, including MLL1 (C), MLL2, and WDR5, were associated with either UTX or JMJD3 or both and such association was elevated in EC upon exposure to inflammatory stimuli. Dynamic enrichment of H3K4me3 and loss of H3K27me3 at Notch‐associated gene promoters caused ADAM17 and Jagged‐1 derepression and abrupt Notch activation. Conversely, either reducing H3K4me3 or increasing H3K27me3 in EC undergoing inflammation attenuated Notch activation, endothelial inflammation, and apoptosis. Together, these findings indicate that dynamic chromatin modifications may cause an inflammatory and apoptotic switch of EC and that epigenetic reprogramming can potentially improve outcomes in endothelial inflammation‐associated cardiovascular diseases.
Genetic and phenotypic heterogeneity in KIAA0753‐related ciliopathies

Primary ciliopathies are heterogenous disorders resulting from perturbations in primary cilia form and/or function. Primary cilia are cellular organelles which mediate key signaling pathways during development, such as the sonic hedgehog (SHH) pathway which is required for neuroepithelium and central nervous system development. Joubert syndrome is a primary ciliopathy characterized by cerebellar/brain stem malformation, hypotonia, and developmental delays. At least 35 genes are associated with Joubert syndrome, including the gene KIAA0753, which is part of a complex required for primary ciliogenesis. The phenotypic spectrum associated with biallelic pathogenic variants in KIAA0753 is broad and not well‐characterized. We describe four individuals with biallelic pathogenic KIAA0753 variants, including five novel variants. We report in vitro results assessing the function of each variant indicating that mutant proteins are not fully competent to promote primary ciliogenesis. Ablation of KIAA0753 in vitro blocks primary ciliogenesis and SHH pathway activity. Correspondingly, KIAA0753 patient fibroblasts have a deficit in primary ciliation and improper SHH and WNT signaling, with a particularly blunted response to SHH pathway stimulation. Our work expands the phenotypic spectrum of KIAA0753 ciliopathies and demonstrates the utility of patient‐focused functional assays for proving causality of genetic variants.
CaR: A Cutting and Repulsion-Based Evolutionary Framework for Mixed-Integer Programming Problems

A mixed-integer programming (MIP) problem contains both constraints and integer restrictions. Integer restrictions divide the feasible region defined by constraints into multiple discontinuous feasible parts. In particular, the number of discontinuous feasible parts will drastically increase with the increase of the number of integer decision variables and/or the size of the candidate set of each integer decision variable. Due to the fact that the optimal solution is located in one of the discontinuous feasible parts, it is a challenging task to solve a MIP problem. This article presents a cutting and repulsion-based evolutionary framework (called CaR) to solve MIP problems. CaR includes two main strategies: 1) the cutting strategy and 2) the repulsion strategy. In the cutting strategy, an additional constraint is constructed based on the objective function value of the best individual found so far, the aim of which is to continuously cut unpromising discontinuous feasible parts. As a result, the probability of the population entering a wrong discontinuous feasible part can be decreased. In addition, in the repulsion strategy, once it has been detected that the population has converged to a discontinuous feasible part, the population will be reinitialized. Moreover, a repulsion function is designed to repulse the previously explored discontinuous feasible parts. Overall, the cutting strategy can significantly reduce the number of discontinuous feasible parts and the repulsion strategy can probe the remaining discontinuous feasible parts. Sixteen test problems developed in this article and two real-world cases are used to verify the effectiveness of CaR. The results demonstrate that CaR performs well in solving MIP problems.
Langmuir and Freundlich Isotherms for Describing Lead (II) Adsorption on Pretreated Macrofungus (Agaricus bisporus)

Studies have shown that fungal organisms possess the capacity of heavy metal removal. In the present investigation, a study in batch system was conducted using the macrofungus, Agaricus bisporus as biosorbent for evaluating its potentiality to adsorb lead (II) ions from aqueous solution. To improve the bioadsorption capacity, the biosorbent was pretreated with NaOH, Na 2 CO 3 and NaHCO 3 . Pretreatment with NaOH resulted in a significant improvement in bioadsorption capacity. The experimental equilibrium data were adjusted by adsorption isotherms from Langmuir and Freundlich models and their equilibrium parameters were determined. For the untreated biosobent, the Langmuir model supplied q max = 28.8 mg/g and b = 0.02 L/mg and for the Freundlich model parameters are K f = 1.7 and n =1.8. For the sodium hydroxide (NaOH) treated biomass, the parameters were q max = 34.6 mg/g, b= 0.08 L/mg, K f = 5.3 and n = 2.3. The best adjusted model to the experimental equilibrium data for both untreated and sodium hydroxide (NaOH) treated biosorbent was the Langmuir model.
Nicotiana paulineana, a new Australian species in Nicotiana section Suaveolentes

Abstract. Nicotiana is found predominantly in the Americas and Australia, but also has representatives in Africa and the Pacific Islands. All native Australian Nicotiana species belong to section Suaveolentes. The number of species in this section is uncertain and subject to revision. An example of this uncertainty is the taxonomic status of a South Australian Nicotiana accession colloquially termed ‘Corunna’. Here, we report sequences for nuclear and plastid markers for N. sp. Corunna (D.E.Symon 17088) and accessions of two other Australian species, N. burbidgeae and N. benthamiana. Phylogenetic comparison of these sequences with those of other members of Nicotiana places all three taxa in N. section Suaveolentes and shows that ‘Corunna’ represents a distinct phylogenetic lineage in a well supported clade along with N. goodspeedii, N. maritima, N. amplexicaulis and N. suaveolentes. Phenetic analysis of floral characters also supports recognition of N. sp. Corunna (D.E.Symon 17088) as a distinct species, which we describe here as Nicotiana paulineana Newbigin & P.M. Waterh. , sp. nov. The enlarged molecular dataset described here contributes to a better understanding of taxonomic relationships within the section.
First Record of Mawsoniid Coelacanths (Actinistia, Sarcopterygii) from the Marine Rhaetian (Upper Triassic) of Bonenburg, Germany

ABSTRACT Coelacanths are represented today by a single genus, Latimeria. They are known to be ‘living fossils’, because their evolutionary history dates back into the Devonian. Through the Upper Triassic, coelacanths are represented by two families, the Latimeriidae and Mawsoniidae. While latimeriids represent their marine lineage, mawsoniids were, until recently (Deesri et al., 2018), thought to be exclusively freshwater inhabitants. Through the Late Triassic, mawsoniids originated in freshwater environments of America, and only little is known about their evolution in Europe during this time period. Here we report on two morphotypes of mawsoniid basisphenoids from the marine Rhaetian (Upper Triassic) Bonenburg locality (Kreis Höxter, North Rhine-Westphalia, Germany) showing that (1) Late Triassic coelacanths from Germany can be assigned to the family level, specifically to Mawsoniidae, (2) mawsoniid coelacanths were already present in Europe in the Late Triassic, and (3) these inhabited marine environments at the end of the Triassic, supporting the affinities of habitat preference of previous finds from France (Deesri et al., 2018). The results strengthen the hypothesis an intermediate marine phase between the origin of Mawsoniidae in freshwater environments of nowadays North America during the Late Triassic and their final occurrence in continental deposits of Western Gondwana (Africa and South America) and nowadays Europe in the Late Cretaceous (Cavin et al., 2019).
