The PCA showed that ecological strategies of bryophytes in response to levels of irradiation were specialized in branch dwellers, although those of ground and trunk dwellers were less distinct. Conclusions Environmental filtering shaped the combination of functional traits and the spatial distribution of bryophytes along the vertical gradients. Bryophyte species from the upper canopy of cloud forests show narrow variation in functional traits in high-light intensity, whereas species in the lower vertical strata associated with low-light intensity used contrasting, but more diverse ecological strategies.Innovations in foraging behavior can drive morphological diversity by opening up new ways of interacting with the environment, or limit diversity through functional constraints associated with different foraging behaviors. Several classic examples of adaptive radiations in birds show increased variation in ecologically relevant traits. However, these cases primarily focus on geographically narrow adaptive radiations, consider only morphological evolution without a biomechanical approach, or do not investigate tradeoffs with other non-focal traits that might be affected by use of different foraging habitats. Here, we use X-ray microcomputed tomography, biomechanical modeling, and multivariate comparative methods to explore the interplay between foraging behavior and cranial morphology in kingfishers, a global radiation of birds with variable beaks and foraging behaviors, including the archetypal plunge-dive into water. Our results quantify covariation between the shape of the outer keratin covering (rhamphotheca) and the inner skeletal core of the beak, as well as highlight distinct patterns of morphospace occupation for different foraging behaviors and considerable rate variation among these skull regions. We anticipate these findings will have implications for inferring beak shapes in fossil taxa and inform biomimetic design of novel impact-reducing structures.Patients with metastatic breast cancer (MBC) have limited therapeutic options and novel treatments are critically needed. Prior research implicates tumor-induced mobilization of myeloid cell populations in metastatic progression, as well as being an unfavorable outcome in MBC; however, the underlying mechanisms for these relationships remain unknown. Here, we provide evidence for a novel mechanism by which p38 promotes metastasis. Using triple-negative breast cancer models, we showed that a selective inhibitor of p38 (p38i) significantly reduced tumor growth, angiogenesis, and lung metastasis. Importantly, p38i decreased the accumulation of myeloid populations, namely, myeloid-derived suppressor cells (MDSCs) and CD163+ tumor-associated macrophages (TAMs). p38 controlled the expression of tumor-derived chemokines/cytokines that facilitated the recruitment of protumor myeloid populations. Depletion of MDSCs was accompanied by reduced TAM infiltration and phenocopied the antimetastatic effects of p38i. Reciprocally, p38i increased tumor infiltration by cytotoxic CD8+ T cells. Furthermore, the CD163+ /CD8+ expression ratio inversely correlated with metastasis-free survival in breast cancer, suggesting that targeting p38 may improve clinical outcomes. Overall, our study highlights a previously unknown p38-driven pathway as a therapeutic target in MBC.The chemoresistance of tumors is the main barrier to cancer treatment. Interleukin-22 (IL-22) plays an important role in the chemoresistance of multi-cancers; however, the roles of IL-22 in the paclitaxel resistance of lung adenocarcinoma cells remain to be investigated. The present study aims to investigate the potential mechanisms of IL-22 enhancing the chemoresistance of lung adenocarcinoma cells to paclitaxel. We cultured A549, H358, and A549/PTX cell lines. qRT-PCR and western blot assays were performed to examine the mRNA and/or protein levels of IL-22 in A549, A549/PTX, H358, and H358/PTX. Moreover, cells were transfected with IL-22 siRNA1, IL-22 siRNA2, and siRNA NC, and treated with paclitaxel, and the proliferation rate of lung adenocarcinoma cells was evaluated by MTT assay. Flow cytometry was conducted to determine the apoptosis rate of lung adenocarcinoma cells. Telratolimod The results showed that the expression of IL-22 in lung adenocarcinoma tissues was higher than that in normal tissues, and the expression of IL-22 was higher in A549/PTX and H358/PTX compared with A549 and H358 cells. Meanwhile, the expression of IL-22 was strongly correlated with smoking history and TMN stage, as well. Furthermore, IL-22 siRNA inhibited the proliferation and promoted the apoptosis of A549/PTX and H358/PTX cells, and IL-22 siRNA also suppressed the expression levels of AKT and Bcl-2 and increased the expression levels of Bax and cleaved caspase 3. To sum up, IL-22 may mediate the chemosensitivity of lung adenocarcinoma cells to paclitaxel through inhibiting the AKT signaling pathways.Prior research regarding robotic surgery (RS) has largely focused on the engineering or medical aspects of these tools. A few studies have examined consumer opinions toward, or willingness to use, robotic surgeons; however, no study to date has examined what type of person would be willing to undergo RS. Across two studies, the current research fills this gap by building both a descriptive and predictive regression model used to predict what type of user would be willing to undergo RS. To build the descriptive model, 1324 potential patients were asked a series of questions about demographics, attitudes, opinions, and personalities. Results indicate that perceived value, familiarity, wariness of new technologies, fear of surgery, openness, anger, fear, and happiness are all significant predictors of willingness to undergo RS. A regression equation was developed and then used to predict scores in a second study with 1335 potential patients. The scores from both studies were compared for model fit. Several methods were used to validate the regression model, including correlational analyses, a t test, and calculation of the cross-validity coefficient. All three stringent tests showed strong model fit, explaining 62% of the variance in the model. These findings have both practical and theoretical values to the field and can be used to identify early adopters of this advanced medical technology.
