6-, 5.5-, and 2.6-fold, respectively, compared to the WT. Minigenome assays revealed a 46% loss of polymerase activity for the E23K substitution vs the WT while the I38T and I38M PA variants retained ≈80% of activity. Peak viral titers were comparable for the WT, I38T and I38M recombinants (7.95 ± 0.5, 7.45 ± 0.25 and 8.11 ± 0.28 logTCID50/mL), respectively, whereas it was significantly lower for the E23K mutant (6.28 ± 0.28 logTCID50/mL;P less then 0.05 vs the WT). In mice, the WT, I38T and I38M recombinants induced mortality rates of 60%, 40% and 100%, respectively and similar lung viral titers were obtained for the three groups at days 3 and 6 p.i. In conclusion, the fitness of BXA-resistant I38T and I38M PA mutants appears unaltered in contemporary influenza B viruses warranting surveillance for their emergence. Although many people intend to eat healthily, their actual snacking behavior is often marked by a high consumption of calorie-dense, unhealthy snacks. One reason for this discrepancy may be that people tend to associate unhealthy food with tasty food, preventing them to follow up on their healthy snacking goals. To support people in snacking more healthily according to their intentions, there is an urgent need to better understand how people perceive the 'ideal snack', which may eventually be used to make healthy snacks more attractive. In the present research, we aim to elucidate conceptions of ideal snacks without loaded connotations of healthy and unhealthy, and subsequently compare them to features that are associated with healthy and unhealthy snacks. A Dutch community sample (N = 1087) was asked to generate conceptions of their ideal snack, and name features of what they considered to be (un)healthy snacks. The results revealed a multitude of idiosyncratic ideal snack conceptions. Commonalities were sensory characteristics and the notion of 'healthy'. Healthy and unhealthy snacks were primarily associated with their positive or negative consequences for health. These findings may inform the design and marketing of healthy, nutritionally balanced snacks that are palatable and attractive to the very people that make food choices. Fish has several benefits that make it a desirable part of a healthy diet. It is also a high-protein product that can be used as a relatively efficient meat replacer. Both from a health and sustainability perspective, however, it is important to consider the optimum number of fish servings per week and to examine whether fish and plant protein can be brought under the same heading of alternative protein sources. To explore the consumer perspective on these issues, this paper draws on a brief literature study and a re-analysis of survey data from the Netherlands collected earlier. The hypothesis was that affinities with fish consumption and plant-based protein sources are to a certain extent related to each other, based on common relationships with food involvement, which set them apart from meat. The results showed that the hypothesis needed to be nuanced fish consumption was associated exclusively with affinity with spicy meals based on authentic plant protein sources (e.g. nuts) and this relationship was partially based on food involvement. The results are in line with current Dutch recommendations that encourage consumers to eat one serving of fish per week and that stimulate those who already eat more than one serving of fish to replace the rest by plant-based protein sources. Recent advances in the field of taste physiology have clarified the role of different basic taste modalities and their implications in health and disease and proposed emphatically that there might be a distinct cue for oro-sensory detection of dietary long-chain fatty acids (LCFAs). Hence, fat taste can be categorized as a taste modality. During mastication, LCFAs activate tongue lipid sensors like CD36 and GPR120 triggering identical signaling pathways as the basic taste qualities do; however, the physico-chemical perception of fat is not as distinct as sweet or bitter or other taste sensations. The question arises whether "fat taste" is a basic or "alimentary" taste. There is compelling evidence that fat-rich dietary intervention modulates fat taste perception where an increase or a decrease in lipid contents in the diet results, respectively, in downregulation or upregulation of fat taste sensitivity. Evidently, a decrease in oro-sensory detection of LCFAs leads to high fat intake and, consequently, to obesity. Darapladib purchase In this article, we discuss recent relevant advances made in the field of fat taste physiology with regard to dietary fat preference and lipid sensors that can be the target of anti-obesity strategies. Acquired multidrug resistance of cancer cells challenges the chemotherapeutic interventions. To understand the role of molecular chaperone, Hsp90 in drug adapted tumor cells, we have used in vitro drug adapted epidermoid tumor cells as a model system. We found that chemotherapeutic drug adaptation of tumor cells is mediated by induced activities of both Hsp90 and P-glycoprotein (P-gp). Although the high-affinity conformation of Hsp90 has correlated with the enhanced drug efflux activity, we did not observe a direct interaction between P-gp and Hsp90. The enrichment of P-gp and Hsp90 at the cholesterol-rich membrane microdomains is found obligatory for enhanced drug efflux activity. Since inhibition of cholesterol biosynthesis is not interfering with the drug efflux activity, it is presumed that the net cholesterol redistribution mediated by Hsp90 regulates the enhanced drug efflux activity. Our in vitro cholesterol and Hsp90 interaction studies have furthered our presumption that Hsp90 facilitates cholesterol redistribution. The drug adapted cells though exhibited anti-proliferative and anti-tumor effects in response to 17AAG treatment, drug treatment has also enhanced the drug efflux activity. Our findings suggest that drug efflux activity and metastatic potential of tumor cells are independently regulated by Hsp90 by distinct mechanisms. We expose the limitations imposed by Hsp90 inhibitors against multidrug resistant tumor cells. V.Neutrophils, the most abundant circulating leukocytes in human, play an indispensable role in the innate immune response to microbial infections. However, the contribution of tumor-associated neutrophils (TANs) to cancer progression and tumor immunity has been a matter of debate for decades. A higher neutrophil-to-lymphocyte ratio is associated with adverse overall survival in many solid tumors. Preclinical evidence exists to support both anti-tumor and pro-tumor activities of TANs, and TANs employ diverse mechanisms to influence tumor progression and metastasis. Here, we focus our review on the immunosuppressive mechanism of TANs and highlight how neutrophils can operate to dampen both innate and adaptive immunity to promote tumorigenesis. Here we discuss the intriguing and sometimes controversial connection between TANs and granulocytic/polymorphonuclear myeloid-derived suppressor cells (G/PMN-MDSCs). The molecular mechanisms underlying neutrophils' role in immunosuppression provide potential therapeutic targets for cancer treatment, either as monotherapies or as a part of combinatorial regimens. Therefore, we also highlight a number of neutrophil-targeting approaches that may improve the efficacy of current anticancer therapies, especially cancer immunotherapy. Currently interest is surging in the understanding and targeting of immunosuppressive neutrophils, with the goal of developing novel therapeutic strategies in the battle against cancer. Local anesthetics are widely used during clinical cancer surgeries. Studies have suggested that the use and the type of anesthesia affect cancer outcomes. In vivo studies and clinical data show that the use of local anesthetics is potentially beneficial for cancer treatment. However, the effect of the use of local anesthetics on the survival rate of cancer patients following surgery is controversial and, so far, little is known about the direct effects of local anesthetics on cancer cells. This work reviews and summarizes the published literature regarding the preclinical research methods and findings on the influence of local anesthetics on cancer cells. We hope that a thorough understanding of this subject will help to define optimal anesthetic regimens that lead to better outcomes for clinical cancer patients. The sleep onset (SO) process is characterized by gradual electroencephalographic (EEG) changes. The interest for the possibility to manipulate the electrophysiological pattern of the wake-sleep transition is recently growing. This review aims to describe the EEG modifications of the SO process in healthy humans and the evidence about their experimental manipulation. We provide an overview of the electrophysiological changes during the wake-sleep transition, considering several methods to study the EEG signals. We then describe the impact of sleep deprivation (SD) on the electrophysiology of SO. Finally, we discuss the evidence about the possibility to modulate the local EEG activity through transcranial current stimulation protocols with the aim to promote, hinder, or manipulate the electrophysiological mechanisms of the wake-sleep transition. The reviewed findings highlight the local nature of the EEG processes during the SO and their intensification and speedup after SD. The evidence about the possibility to non-invasively affect the EEG pattern of the wake-sleep transition may have important implications for clinical conditions that would benefit from its prevention or promotion. Threat conditioning is a laboratory model of associative learning across species that is often used in research on the etiology and treatment of anxiety disorders. At least 10 different conditioned responses (CR) for quantifying learning in human threat conditioning are found in the literature. In this narrative review, we discuss these CR by considering the following questions (1) Are the CR indicators of amygdala-dependent threat learning? (2) To what components of formal learning models do the CR relate? (3) How well can threat learning be inferred from the CR? Despite a vast literature, these questions can only be answered for some CR. Among the CR considered, heart period, startle eye-blink and Pavlovian-to-instrumental transfer are most clearly related to amygdala-dependent threat learning. Formal learning models have mostly been studied for skin conductance responses, which are likely to reflect threat prediction and its uncertainty. Startle eye-blink and pupil size appear to best differentiate CS+/CS-, although few direct comparisons between CR exist. We suggest future directions for improving the quantification of threat conditioning. Orf, caused by orf virus (ORFV), is an important zoonotic disease that infects goat and sheep, leading to huge economic losses. ORFV can also cause cutaneous lesions in people who come in close contact with the diseased animals. Although accurate diagnostic methods for ORFV infection exist, there is a need for a rapid, specific, and sensitive method for easy clinical application. Here, we successfully established a recombinase-aided amplification (RAA) assay for rapid detection of ORFV. The analytical sensitivity of the assay for ORFV detection is 1 × 101 copies per reaction. Moreover, no cross-reaction was observed with other common DNA viruses. A total of 45 archived suspected ORFV infected nasal scab skin samples were examined by RAA and SYBR Green-based real-time polymerase chain reaction (PCR). Compared with the real-time PCR assay, the kappa values of the RAA assay for ORFV detection was 0.845 (p less then 0.001), indicating that both assay results were fully in agreement. In conclusion, this detection assay provides a rapid, sensitive, and specific method for ORFV detection and is suitable for ORFV clinical testing.
