Non-vitamin K antagonist oral anticoagulants (NOACs) are a therapeutic option to prevent stroke in patients with atrial fibrillation (AF). In fact, NOACs have become the recommended choice by international clinical practice guidelines over vitamin K antagonists (VKA), because of their efficacy and safety profile, especially in newly initiated patients. The more predictable pharmacokinetic and pharmacodynamic profile of this family of drugs allows preventing anticoagulation drug monitoring. Furthermore, NOACs have significantly fewer drug and food interactions in comparison with VKAs. Despite this, there are no studies that compare the effects on the quality of anticoagulation of NOACs with the intake of potential interactions drugs of P-glycoprotein and cytochrome P450 (CYP). This review brings an overview of NOACs pharmacokinetics profile and their potential drug-food interactions. We also briefly discuss the potential role of prebiotics and probiotics in patients under therapy with NOACs.

Marine bacteria in the seawater and seafloor are essential parts of Earth’s biodiversity, as they are critical participants of the global energy flow and the material cycles. However, their spatial-temporal variations and potential interactions among varied biotopes in artificial habitat are poorly understood. In this study, we profiled the variations of bacterial communities among seasons and areas in the water and sediment of artificial reefs using 16S rRNA gene sequencing, and analyzed the potential interaction patterns among microorganisms. Distinct bacterial community structures in the two biotopes were exhibited. The Shannon diversity and the richness of phyla in the sediment were higher, while the differences among the four seasons were more evident in the water samples. The seasonal variations of bacterial communities in the water were more distinct, while significant variations among four areas were only observed in the sediment. Correlation analysis revealed that nitrite and mud content were the most important factors influencing the abundant OTUs in the water and sediment, respectively. Potential interactions and keystone species were identified based on the three co-occurrence networks. Results showed that the correlations among bacterial communities in the sediment were lower than in the water. Besides, the abundance of the top five abundant species and five keystone species had different changing patterns among four seasons and four areas. These results enriched our understanding of the microbial structures, dynamics, and interactions of microbial communities in artificial habitats, which could provide new insights into planning, constructing and managing these special habitats in the future.

SGT1 (suppressor of the skp1 G2 allele) is an important plant disease resistance-related protein, which plays an important role in plant resistance to pathogens and regulates signal transduction during the process of plant disease resistance. In this study, we analyzed the expression profile of SbSGT1 in sorghum under phytohormones treatment. Quantitative real-time PCR results showed that SbSGT1 was most expressed in sorghum leaves, and could respond to plant hormones such as auxin, abscisic acid, salicylic acid, and brassinolide. Subsequently, we determined the optimal soluble prokaryotic expression conditions for SbSGT1 and purified it using a protein purification system in order to evaluate its potential interactions with plant hormones. Microscale thermophoretic analysis showed that SbSGT1 exhibited significant interactions with indole-3-acetic acid (IAA), with a Kd value of 1.5934. Furthermore, the transient expression of SbSGT1 in Nicotiana benthamiana indicated that treatment with exogenous auxin could inhibit SbSGT1 expression, both at the transcriptional and translational level, demonstrating that there exists an interaction between SbSGT1 and auxin.

Background: Antibiotic prophylaxis in orthopedic surgery cases aims to prevent surgery site infections (SSI). For antibiotic prophylaxis, it is recommended to use the first generation of cephalosporin, namely cefazolin which can kill the bacteria commonly found in orthopedic surgery infection. The prophylactic administration of cefotaxime is not the first line but is definitive for surgical prophylaxis. Objective: The aim of this study was to determine the rationale for the use of antibiotic prophylaxis for orthopedic surgery, the drug problems (DRPs) that occurred and their potential interactions. Method: This study was conducted using a cross sectional design with a total sampling technique of medical record samples from January to February 2019 at the Government Hospital in Yogyakarta. Observational analytical descriptive data processing by ensuring the appropriate of indications, route of administration, timing of administration and an appropriate of prophylactic doses as well as how to compare DPRs to the literature and analysis of potential co drug interaction with Drug Information Handbook (DIH), AHFS Clinical Drug Information, Drug Interaction Facts, and Interactions Stockley’s Drug Interaction. Results: All patients received appropriate therapy for indication, type of drug, routes of administration for pre and postoperative. All patients received an under dose of ranitidine and 1 patient (1,69%) received an over dose of piracetam. Potential interactions that occur include ketorolac-ranitidine, NSAIDs with other NSAIDs, NSAIDs-ranitidine, NSAIDs-ACEi, NSAIDs-bisoprolol, bisoprolol-calcium, calcium-vitamin C, and paracetamol-ranitidine. Conclusion: Pre and postoperative prophylactic antibiotics are rational. The accompanying drug, ranitidine and piracetam were not properly doses. Drug interactions in this study are potential. Keywords: prophylaxis antibiotic, orthopedic surgery, cefotaxim, DRPs

Purpose: During a crisis, an individual with a communication disability or difference is at risk of communication breakdowns that could unintentionally escalate the crisis. The goal of this preliminary study was to identify how first responders from various organizations may respond given scenarios presenting potential interactions with an individual with a communication impairment or difference. Method: Three adult participants currently serving as first responders completed semistructured interviews. Participants were asked how they would react in different hypothetical scenarios, all incorporating aspects of communication disorders and differences that could be misinterpreted. Data analysis consisted of transcribing the responses to each scenario and identifying the themes. Results: Participants across organizations receive general communication and disability training, rely on established procedures, problem-solving, open-mindedness, and use of departmental resources in their interactions. Conclusions: This preliminary study illustrates awareness of existing protocols and organizational supports that may support interactions with individuals with communication disorders and differences. Potential areas for additional resources and training include the use of augmentative and alternative communication and disability-specific education.

Any drug is potentially associated with the risk of adverse drug reactions (ADRs), the incidence of which in developed and developing countries is estimated at 6.3 (3.3—11.0) and 5.5 % (1.1—16.9), respectively. Many ADRs increase mortality and / or morbidity and / or cause clinical manifestations that require a patient to seek medical help or hospitalization; a special term has been introduced — drug-induced diseases. Food can interact with drugs and increase the risk of ADRs, including serious ones. The simultaneous intake of food and drugs can affect the bioavailability, pharmacokinetics, pharmacodynamics and therapeutic efficacy of drugs due to changes in drug absorption and metabolism. A striking example of the effect of food on the pharmacokinetic profile of drugs is the change in the bioavailability of the tyrosine kinase inhibitor lapatinib: compared with taking on an empty stomach, the bioavailability of lapatinib in a single dose of 1 500 mg after taking it together with high-calorie standard food increases by an average of 325 % — 4.25 times. In other words, the concentration of the drug in the blood serum after taking one tablet at the same time with food is comparable to taking 4 tablets on an empty stomach. Currently, there are no recommendations for choosing a dosage regimen for drugs depending on the qualitative and quantitative composition of food, as well as taking into account potential interactions with food components, although these recommendations are extremely necessary for patients and healthcare professionals. In this regard, this article summarizes the data available at the time of writing in open sources concerning the effect of food on the absorption and metabolism of drugs, and also describes the possible mechanisms of interaction.

Abstract Alcohol- and alkane-forming pathways in cuticular wax biosynthesis are well characterized in Arabidopsis. However, potential interactions between the two pathways remain unclear. Our study revealed that mutation of CER4, the key gene in the alcohol-forming pathway, also led to a deficiency in alkane-forming pathway in distal stems. To trace the connection between these two pathways, we characterized two homologs of fatty alcohol oxidase (FAO), FAO3 and FAO4b, which were highly expressed in distal stems and localized to the endoplasmic reticulum. The amounts of waxes from the alkane-forming pathway were significantly decreased in stems of fao4b, and much lower in fao3 fao4b, indicative of an overlapping function for both proteins in wax synthesis. Additionally, overexpression of FAO3 and FAO4b in Arabidopsis resulted in a dramatic reduction of primary alcohols and significant increase of aldehydes and related waxes. Moreover, expressing FAO3 or FAO4b led to significantly decreased amounts of C18 - C26 alcohols in yeast co-expressing CER4 and FAR1. Collectively, these findings demonstrate that FAO3 and FAO4b are functionally redundant in suppression of primary alcohols accumulation and contribution to aldehyde production, which provides a missing and long sought-after link between the two pathways in wax biosynthesis.

Abstract Background Grapevine trunk diseases (GTDs) is a disease complex caused by wood pathogenic fungi belonging to genera like Phaeomoniella, Phaeoacremonium, Fomitiporia, Eutypa and members of the family Botryosphaeriaceae. However, the co-occurrence of these fungi in symptomatic and asymptomatic vines at equivalent abundances has questioned their role in GTDs. Hence, we still lack a good understanding of the fungi involved in GTDs, their interactions and the factors controlling their assemblage in vines. We determined the fungal and bacterial microbiome in wood tissues of asymptomatic and symptomatic vines of three main Greek cultivars (Agiorgitiko, Xinomavro, Vidiano), each cultivated in geographically distinct viticultural zones, using amplicon sequencing. Results We noted that cultivar/biogeography (lumped factor) was the strongest determinant of the wood fungal microbiome (p < 0.001, 22.7%), while GTD symptoms condition had a weaker but still significant effect (p < 0.001, 3.5%), being prominent only in the cultivar Xinomavro. Several fungal Amplicon Sequence Variants (ASVs), reported as GTD-associated pathogens like Kalmusia variispora, Fomitiporia spp., and Phaemoniella chlamydosporα (most dominant in our study), were positively correlated with symptomatic vines in a cultivar/viticultural zone dependent manner. Random Forest analysis pointed to P. chlamydosporα, K. variispora, A. alternata and Cladosporium sp., as highly accurate predictors of symptomatic vines (0% error rate). The wood bacterial microbiome showed similar patterns, with biogeography/cultivar being the main determinant (p < 0.001, 25.5%) of its composition, followed by the GTD status of vines (p < 0.001, 5.2%). Differential abundance analysis revealed a universal positive correlation (p < 0.001) of Bacillus and Streptomyces ASVs with asymptomatic vines. Network analysis identified a significant negative co-occurrence network between these bacterial genera and Phaemoniella, Phaeoacrominum and Seimatosporium. These results point to a plant beneficial interaction between Bacillus/Streptomyces and GTD pathogens. Conclusions Our study (a) provides evidence that GTD symptomatic plants support a wood fungal microbiome, showing cultivar and biogeography-dependent patterns, that could be used as a proxy to distinguish between healthy and diseased vines, (b) points to strong interactions between the bacterial and fungal wood microbiome in asymptomatic vines that should be further pursued in the quest for discovery of novel biocontrol agents.

Serum is commonly used as a specimen in immunoassays but the presence of heterophilic antibodies can potentially interfere with the test results. Previously, we have developed a microfluidic device called: 3D Stack for enzyme-linked immunosorbent assay (ELISA). However, its evaluation was limited to detection from a single protein solution. Here, we investigated the sensitivity of the 3D Stack in detecting a severe dengue biomarker—soluble CD163 (sCD163)—within the serum matrix. To determine potential interactions with serum matrix, a spike-and-recovery assay was performed, using 3D Stacks with and without surface modification by an EDC–NHS (N-ethyl-N′-(3-(dimethylamino)propyl)carbodiimide/N-hydroxysuccinimide) coupling. Without surface modification, a reduced analyte recovery in proportion to serum concentration was observed because of the Vroman effect, which resulted in competitive displacement of coated capture antibodies by serum proteins with stronger binding affinities. However, EDC–NHS coupling prevented antibody desorption and improved the sensitivity. Subsequent comparison of sCD163 detection using a 3D Stack with EDC–NHS coupling and conventional ELISA in dengue patients’ sera revealed a high correlation (R = 0.9298, p < 0.0001) between the two detection platforms. Bland–Altman analysis further revealed insignificant systematic error between the mean differences of the two methods. These data suggest the potentials of the 3D Stack for further development as a detection platform.
