FGF10 enhances yak oocyte fertilization competence and subsequent blastocyst quality and regulates the levels of CD9, CD81, DNMT1, and DNMT3B

The fusion of sperm and oocytes determines the fertilization competence and subsequent development of embryos, which, in turn, can be affected by various proteins and DNA methylation. However, several factors in this whole regulation process remain unknown, especially in yaks. Here, we report that fibroblast growth factor 10 (FGF10) is an important growth factor that can enhance the maturation rate of yak oocytes and the motility of frozen spermatozoa. Subsequent blastocyst quality was also improved by increasing the total cell number and level of pregnancy‐associated protein in blastocysts. These effects were significantly high in the group that received the 5 ng/ml FGF10 treatment, during both in vitro maturation (IVM) and capacitation. Our data show that the effects of FGF10 were dose‐dependent at vital steps of embryogenesis in vitro. Furthermore, quantitative polymerase chain reaction, western blot analysis, and immunofluorescence demonstrated that the levels of CD9, CD81, DNMT1, and DNMT3B in both mature cumulus‐oocyte complexes and capacitated sperms were regulated by FGF10, which was also highly expressed in the group treated with 5 ng/ml FGF10 during both IVM and capacitation. From our present study, we concluded that FGF10 promotes yak oocyte fertilization competence and subsequent blastocyst quality, and could also regulate CD9, CD81, DNMT1, and DNMT3B to optimize sperm–oocyte interactions and DNA methylation during fertilization.
Hypoglycemia in Patients with Diabetes who Are Fasting for Laboratory Blood Tests: The Cape Girardeau Hypoglycemia En Route Prevention Program

Abstract Objective: Patients with diabetes are routinely asked to fast for laboratory tests. If not properly prepared, they may be at risk for hypoglycemia, which may result in traffic accidents while driving en route to and from laboratory facilities. We undertook this study to evaluate the magnitude of this overlooked problem, and to evaluate the effectiveness of a prevention program implemented in our clinic. Methods: A retrospective study consisting of chart reviews and telephone interviews of consecutive hypoglycemic events (blood glucose level < 70 mg/dL). The study cohorts, A and B, were extracted from our central laboratory database. Cohort A (from January 2008–September 2009) consisted of patients prior to–and cohort B (from October 2009–June 2011) subsequent to–the implementation of a prevention program involving blood glucose monitoring and adjustment of antidiabetic medications. Duration of each cohort was 21 months. For the purpose of this article, we use the acronym FEEHD (fasting–evoked en–route hypoglycemia in diabetes) to describe this overlooked form of hypoglycemia. Results: Of a total of 1801 blood glucose test results retrieved, cohort A included a total of 55 hypoglycemic events in 51 patients (4 patients with 2 events each). Cohort B included a total of 23 hypoglycemic events in 22 patients (with 1 patient sustaining 2 events) out of a total of 2561 blood glucose test results retrieved. In cohort A, of 35 patients on antidiabetic medications who recalled fasting or probably fasting, there were 39 hypoglycemic events (2.2% frequency), compared with 18 events (0.7% frequency) in 17 patients in cohort B. This indicates a 68% risk reduction. The frequency of critical hypoglycemia (< 50 mg/dL) was more significantly reduced, from 11 events (0.6%) to 2 events (0.07%), indicating a risk reduction of 88%. Conclusion: This study showed a 68% risk reduction of FEEHD with implementation of the prevention program, and an 88% reduction of severe FEEHD (blood glucose level < 50 mg/dL). Reporting on the first prevention program of its kind, this is the first study to evaluate an overlooked safety problem in diabetes management. Clinicians should consider if fasting laboratory tests are in fact necessary, and when ordered, clinicians should properly instruct their patients on adequate blood glucose monitoring and adjustment of antidiabetic medications. We present the guidelines that proved effective in our program to help patients with diabetes and their clinicians avert this potentially harmful complication.
Association between sleep bruxism and anxiety symptoms in adults: A systematic review

BACKGROUND The purpose of this systematic review was to evaluate the association between sleep bruxism (SB) and anxiety symptoms in adults. METHODS A systematic review was performed and studies assessing SB by means of questionnaires, clinical examination and/or polysomnography (PSG), and validated questionnaires to assess anxiety, were included. Search strategies were developed for seven main electronic databases. Risk of bias was assessed using the Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies, and confidence in cumulative evidence was evaluated using the Grading of Recommendations Assessment, Development and Evaluation criteria. RESULTS Eight cross-sectional studies were included, of which five were judged with low and three with moderate risk of bias. No association with SB was observed in three studies that investigated generic levels of anxiety, while other two papers that evaluated generic anxiety levels through the State-Trait Anxiety Inventory (STAI) found a positive association with probable and definite SB in both STAI-1 and STAI-2 subscales. Only one study evaluated dental anxiety in particular and an association with probable SB was observed regarding very anxious or extremely anxious scores. Two studies assessed specific symptoms of anxiety using the panic-agoraphobic spectra evaluation (PAS-SR) questionnaire. Significantly higher PAS-SR total scores were observed in both studies with regard to SB. No study with definitive assessment of SB was identified. CONCLUSION Current literature is controversial regarding an association between SB and generic symptoms of anxiety in adults. It seems that some specific symptoms of the anxiety disorders spectrum might be associated with probable SB.
The Influence of Mood Versus Relevant Self-Perceptions in Older Adults’ Interest in Negative Health-Related Information

Past research suggests that, although older adults may tend to prefer positive over negative information, they may be more willing to consider relevant negative information when in a positive affective state (Growney & Hess, 2017). However, the underlying mechanism involved in this phenomenon is unclear. In the present study, we aimed to identify this mechanism and disentangle mood and self-perceptions as potential personal resources. In Study 1, young and older adults completed either a positive or negative mood manipulation task, or a health manipulation task designed to accentuate positive or negative perceptions of one’s health-related behaviors. Participants then selected three of six health-related articles to read based on their headlines, half of which were positively worded and half of which were negative, but offered self-corrective information. Participants in the positive health condition selected more negative health-related articles to read than those in the negative health condition, with the effect being specific to older adults. Simple manipulations of mood had no effect on article selection, suggesting that older adults used their positive self-perceptions as a resource for considering negative information. In addition, endorsement of information goals mediated the relationship between manipulated health behavior perceptions and article selections for both young and older adults. Results from Study 2 demonstrate that effects are specific to situations with high-informative versus low-informative content. Our findings suggest that older adults’ willingness to focus on negative self-relevant information is bolstered by enhancing self-perceptions of self within the domain of interest.
Application of Hanging Drop Technique for Kidney Tissue Culture

Background/Aims: The hanging drop technique is a well-established method used in culture of animal tissues. However, this method has not been used in adult kidney tissue culture yet. This study was to explore the feasibility of using this technique for culturing adult kidney cortex to study the time course of RNA viability in the tubules and vasculature, as well as the tissue structural integrity. Methods: In each Petri dish with the plate covered with sterile buffer, a section of mouse renal cortex was cultured within a drop of DMEM culture medium on the inner surface of the lip facing downward. The tissue were then harvested at each specific time points for Real-time PCR analysis and histological studies. Results: The results showed that the mRNA level of most Na+ related transporters and cotransporters were stably maintained within 6 hours in culture, and that the mRNA level of most receptors found in the vasculature and glomeruli were stably maintained for up to 9 days in culture. Paraffin sections of the cultured renal cortex indicated that the tubules began to lose tubular integrity after 6 hours, but the glomeruli and vasculatures were still recognizable up to 9 days in culture. Conclusions: We concluded that adult kidney tissue culture by hanging drop method can be used to study gene expressions in vasculature and glomeruli.
Symbolic labeling in 5-month-old human infants

Significance Humans naturally entertain complex representations of the world based on various symbolic systems, from natural language to mathematical or musical notation. They recode the input into abstract symbolic representations that can be internally manipulated and projected back onto the external world. We show that preverbal infants can redescribe complex percepts into abstract mental variables, which they can readily map onto arbitrary labels. Importantly, we show that, beyond associative learning, infants can readily infer a bidirectional relation between the abstracted representations and the associated labels, a capacity that animals do not spontaneously exhibit. Our findings buttress the hypothesis of symbolic representations in preverbal infants, which may serve as a foundation for our distinctively human learning abilities. Humans’ ability to create and manipulate symbolic structures far exceeds that of other animals. We hypothesized that this ability rests on an early capacity to use arbitrary signs to represent any mental representation, even as abstract as an algebraic rule. In three experiments, we collected high-density EEG recordings while 150 5-month-old infants were presented with speech triplets characterized by their abstract syllabic structure—the location of syllable repetition—which predicted a following arbitrary label (e.g., ABA words were followed by a fish picture, AAB words by a lion). After a brief learning phase, EEG responses to novel words revealed that infants built expectations about the upcoming label based on the triplet structure and were surprised when it happened to be incongruent. Preverbal infants were thus able to recode the incoming triplets into abstract mental variables to which arbitrary labels were flexibly assigned. Importantly, infants also generalized to novel trials in which the pairing order was reversed (with the label preceding the auditory structure). Beyond conditioned associations, infants instantly inferred a bidirectional mapping between the abstract structures and the following label, a foundational operation for any symbolic system.
In-Vitro Evaluation of Different Antimicrobial Combinations with and without Colistin Against Carbapenem-Resistant Acinetobacter Baumannii

Carbapenem-resistant Acinetobacter baumannii (CR-Ab) infections are associated with high morbidity and mortality. The aim of the study was to evaluate the in-vitro activity of different antimicrobial combinations (with and without colistin, COL) against clinical isolates of CR-Ab collected from patients with CR-Ab infection, including unconventional combinations such as COL + VANcomycin (VAN) and COL + rifampin (RIF). CR-Ab strains were collected from hospitalized patients at Sapienza University of Rome. Antimicrobial susceptibility patterns were determined throughout MIC50/90s whereas the synergistic activity was evaluated by qualitative (i.e., checkerboard) and quantitative (i.e., killing studies) methods. All the strains were found oxacillinase (OXA) producers and tigecycline (TIG) sensitive whereas 2 strains were resistant to COL. Application of the checkerboard method indicated complete synergism in COL combinations at different extension: 21.4%, 57.1%, 42.8%, 35.7% for COL + meropenem (MEM), COL + RIF, COL + VAN and COL + TIG, respectively, with the non-conventional combinations COL + VAN and COL + RIF exhibiting the highest rate of synergism. Regarding COL-free combination, complete synergism was observed in 35.7% of the strains for MEM + TIG. Killing studies showed that the combinations COL + MEM, COL + TIG and MEM + TIG were bactericidal and synergistic against both colistin-sensitive and low colistin-resistant strains whereas only the combinations COL + VAN and COL + RIF showed an early and durable bactericidal activity against all the tested strains, with absence of growth at 24 h. This study demonstrated that COL-based combinations lead to a high level of synergic and bactericidal activity, especially COL + VAN and COL + RIF, even in the presence of high level of COL resistance.
Microelectrode recording for deep brain stimulation of the subthalamic nucleus in patients with advanced Parkinson's Disease: advantage or loss of time?

AIM Deep brain stimulation of the subthalamic nucleus in patients with Parkinson's disease (PD) can be performed with or without microelectrode recording (MER). One of the reasons not to use MER is that it increases operation time. Here, we have investigated the effect of performing of MER on operation time. MATERIAL AND METHODS The time spent for MER was calculated for the first and second side in twenty-four patients with PD. The number of microelectrodes used on each trajectory for the first and second side and the permanent electrode implantation percentage on each trajectory for the first and second side were calculated as well. RESULTS The time spent for MER on average was 23.4 ±6.2 min., 17.4 ±6.5 min., and 41.2 ±6.3 min. for the first side, second side and total procedure, respectively. In 75% of the patients the final electrode was implanted at the planned target for the first side and in 61% on the second side. CONCLUSION MER extends operation time of DBS. However, it provides real-time information during surgery on the neurophysiological location of the electrodes and facilitates the choice for an alternative target if the planned target does not produce satisfying results.
Interaction map of Arabidopsis Mediator complex expounding its topology

Abstract Understanding of mechanistic details of Mediator functioning in plants is impeded as the knowledge of subunit organization and structure is lacking. In this study, an interaction map of Arabidopsis Mediator complex was analyzed to understand the arrangement of the subunits in the core part of the complex. Combining this interaction map with homology-based modeling, probable structural topology of core part of the Arabidopsis Mediator complex was deduced. Though the overall topology of the complex was similar to that of yeast, several differences were observed. Many interactions discovered in this study are not yet reported in other systems. AtMed14 and AtMed17 emerged as the key component providing important scaffold for the whole complex. AtMed6 and AtMed10 were found to be important for linking head with middle and middle with tail, respectively. Some Mediator subunits were found to form homodimers and some were found to possess transactivation property. Subcellular localization suggested that many of the Mediator subunits might have functions beyond the process of transcription. Overall, this study reveals role of individual subunits in the organization of the core complex, which can be an important resource for understanding the molecular mechanism of functioning of Mediator complex and its subunits in plants.
Transcription-dependent spreading of the Dal80 yeast GATA factor across the body of highly expressed genes

GATA transcription factors are highly conserved among eukaryotes and play roles in transcription of genes implicated in cancer progression and hematopoiesis. However, although their consensus binding sites have been well defined in vitro, the in vivo selectivity for recognition by GATA factors remains poorly characterized. Using ChIP-Seq, we identified the Dal80 GATA factor targets in yeast. Our data reveal Dal80 binding to a large set of promoters, sometimes independently of GATA sites, correlating with nitrogen- and/or Dal80-sensitive gene expression. Strikingly, Dal80 was also detected across the body of promoter-bound genes, correlating with high expression. Mechanistic single-gene experiments showed that Dal80 spreading across gene bodies requires active transcription. Consistently, Dal80 co-immunoprecipitated with the initiating and post-initiation forms of RNA Polymerase II. Our work suggests that GATA factors could play dual, synergistic roles during transcription initiation and post-initiation steps, promoting efficient remodeling of the gene expression program in response to environmental changes.
Pleural effusion in acute pulmonary embolism in Bahrain: Radiological and pleural fluid characteristics

Background and Objectives: Pleural effusion is seen in around half of the cases of pulmonary embolism (PE). There are no data on the incidence of pleural effusion in cases of PE in the Kingdom of Bahrain. This study was done to determine the frequency and radiological features of pleural effusion in cases of acute PE and also to characterize the pleural fluid biochemistry and cell type in patients subjected to diagnostic thoracentesis. Methods: This was a retrospective, observational single-center study. All the data of patients subjected to computed tomography pulmonary angiography (CTPA) in suspected cases of acute PE over a 4-year period were analyzed. Results: A total of 1756 patients were subjected to CTPA from January 2013 to December 2016. A diagnosis of acute PE was made in 200 patients (11.4%). Pleural effusion was identified in 70 cases (35%). Majority of the effusions were small to moderate in size, bilateral, and associated with peripheral emboli. Consolidation, atelectasis, and ground glass attenuation were common associated findings on CTPA in these patients. Consolidation was more common in patients of PE associated with pleural effusion as compared to those with PE alone (62.85% and 33.8%, respectively, odds rato: 3.279 and 95% confidence interval: 1.798–6.091, P < 0.001). Diagnostic thoracentesis was done in 6 (8.6%) of the cases. All the patients had an exudative effusion with normal glucose values and neutrophil predominance. Conclusion: PE was associated with pleural effusion in around one-third of the patients in Bahrain. The effusions were mainly small and bilateral. The emboli in cases associated with pleural effusion were mostly peripheral. Consolidation was the parenchymal abnormality detected on CTPA which was significantly associated with the presence of pleural effusion. Most of the pleural effusions were not suitable for thoracentesis. In patients subjected to fluid analysis, the effusions were exudative, neutrophilic predominant, and associated with normal glucose levels.
Response of Freshwater Biofilms to Antibiotic Florfenicol and Ofloxacin Stress: Role of Extracellular Polymeric Substances

Antibiotic residues have been detected in aquatic environments worldwide. Biofilms are one of the most successful life forms, and as a result are ubiquitous in natural waters. However, the response mechanism of freshwater biofilms to the stress of various antibiotic residues is still unclear. Here, the stress of veterinary antibiotic florfenicol (FF) and fluoroquinolone antibiotic ofloxacin (OFL) on freshwater biofilms were investigated by determining the changes in the key physicochemical and biological properties of the biofilms. The results showed that the chlorophyll a content in biofilms firstly decreased to 46–71% and then recovered to original content under the stress of FF and OFL with high, mid, and low concentrations. Meanwhile, the activities of antioxidant enzymes, including superoxide dismutase and catalase, increased between 1.3–6.7 times their initial values. FF was more toxic to the biofilms than OFL. The distribution coefficients of FF and OFL binding in extracellular polymeric substances (EPS)-free biofilms were 3.2 and 6.5 times higher than those in intact biofilms, respectively. It indicated that EPS could inhibit the FF and OFL accumulation in biofilm cells. The present study shows that the EPS matrix, as the house of freshwater biofilms, is the primary barrier that resists the stress from antibiotic residues.
Metabolomic Insights into Human Arboviral Infections: Dengue, Chikungunya, and Zika Viruses

The global burden of arboviral diseases and the limited success in controlling them calls for innovative methods to understand arbovirus infections. Metabolomics has been applied to detect alterations in host physiology during infection. This approach relies on mass spectrometry or nuclear magnetic resonance spectroscopy to evaluate how perturbations in biological systems alter metabolic pathways, allowing for differentiation of closely related conditions. Because viruses heavily depend on host resources and pathways, they present unique challenges for characterizing metabolic changes. Here, we review the literature on metabolomics of arboviruses and focus on the interpretation of identified molecular features. Metabolomics has revealed biomarkers that differentiate disease states and outcomes, and has shown similarities in metabolic alterations caused by different viruses (e.g., lipid metabolism). Researchers investigating such metabolomic alterations aim to better understand host–virus dynamics, identify diagnostically useful molecular features, discern perturbed pathways for therapeutics, and guide further biochemical research. This review focuses on lessons derived from metabolomics studies on samples from arbovirus-infected humans.
Stem‐Cell‐Driven Growth and Regrowth of the Adult Spinal Cord in Teleost Fish

The spinal cord of the teleost fish Apteronotus leptorhynchus continues to grow during adulthood, in concert with the overall body growth. Immunohistological studies, combined with mathematical modeling, suggest that this growth is driven by proliferative activity of Sox2‐expressing stem/progenitor cells (SPCs) and by cell drift due to population pressure. The SPCs exhibit high volumetric density in the caudal filament and the ependymal layer. Nevertheless, the majority of these cells are found in the parenchyma throughout the rostro‐caudal axis of the spinal cord, albeit at much lower volumetric densities than in the ependymal layer. The SPCs give rise, via transit‐amplifying cells, to neurons and glia. The relative number of neurons and glia is primarily regulated through apoptosis of supernumerary neurons. Quantitative analysis has demonstrated that the continued cell proliferation results in additive neurogenesis. This addition includes adult‐born spinal electromotoneurons, thereby resulting in a continuous increase in the amplitude of the fish’s electric organ discharge during adult life. Amputation of the caudal part of the spinal cord induces initially a degenerative response, dominated by massive apoptotic cell death in spinal cord tissue immediately rostral to the injury site, and distinguished by a partial loss of the electric organ discharge amplitude. This phase is followed by a regenerative response, characterized by absence of gliosis and by rapid stem‐cell‐driven tissue regrowth. Although the quality of the regenerated tissue is variable among individuals, the structural repair has led in every fish examined thus far to full recovery of the electric organ discharge amplitude.
