Humans can naturally and effectively find salient regions in complex scenes. Motivated by this observation, attention mechanisms were introduced into computer vision with the aim of imitating this aspect of the human visual system. Such an attention mechanism can be regarded as a dynamic weight adjustment process based on features of the input image. Attention mechanisms have achieved great success in many visual tasks, including image classification, object detection, semantic segmentation, video understanding, image generation, 3D vision, multimodal tasks, and self-supervised learning. In this survey, we provide a comprehensive review of various attention mechanisms in computer vision and categorize them according to approach, such as channel attention, spatial attention, temporal attention, and branch attention; a related repository https://github.com/MenghaoGuo/Awesome-Vision-Attentions is dedicated to collecting related work. We also suggest future directions for attention mechanism research.

Background Baicalin, which is isolated from Radix Scutellariae , possesses strong biological activities including an anti-inflammation property. Recent studies have shown that the anti-inflammatory effect of baicalin is linked to toll-like receptor 4 (TLR4), which participates in pathological changes of central nervous system diseases such as depression. In this study, we explored whether baicalin could produce antidepressant effects via regulation of TLR4 signaling in mice and attempted to elucidate the underlying mechanisms. Methods A chronic unpredictable mild stress (CUMS) mice model was performed to explore whether baicalin could produce antidepressant effects via the inhibition of neuroinflammation. To clarify the role of TLR4 in the anti-neuroinflammatory efficacy of baicalin, a lipopolysaccharide (LPS) was employed in mice to specially activate TLR4 and the behavioral changes were determined. Furthermore, we used LY294002 to examine the molecular mechanisms of baicalin in regulating the expression of TLR4 in vivo and in vitro using western blot, ELISA kits, and immunostaining. In the in vitro tests, the BV2 microglia cell lines and primary microglia cultures were pretreated with baicalin and LY292002 for 1 h and then stimulated 24 h with LPS. The primary microglial cells were transfected with the forkhead transcription factor forkhead box protein O 1 (FoxO1)-specific siRNA for 5 h and then co-stimulated with baicalin and LPS to investigate whether FoxO1 participated in the effect of baicalin on TLR4 expression. Results The administration of baicalin (especially 60 mg/kg) dramatically ameliorated CUMS-induced depressive-like symptoms; substantially decreased the levels of interleukin-1 beta (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-α) in the hippocampus; and significantly decreased the expression of TLR4. The activation of TLR4 by the LPS triggered neuroinflammation and evoked depressive-like behaviors in mice, which were also alleviated by the treatment with baicalin (60 mg/kg). Furthermore, the application of baicalin significantly increased the phosphorylation of phosphatidylinositol 3-kinase (PI3K), protein kinase B (AKT), and FoxO1. The application of baicalin also promoted FoxO1 nuclear exclusion and contributed to the inhibition of the FoxO1 transactivation potential, which led to the downregulation of the expression of TLR4 in CUMS mice or LPS-treated BV2 cells and primary microglia cells. However, prophylactic treatment of LY294002 abolished the above effects of baicalin. In addition, we found that FoxO1 played a vital role in baicalin by regulating the TLR4 and TLR4-mediating neuroinflammation triggered by the LPS via knocking down the expression of FoxO1 in the primary microglia. Conclusion Collectively, these results demonstrate that baicalin ameliorated neuroinflammation-induced depressive-like behaviors through the inhibition of TLR4 expression via the PI3K/AKT/FoxO1 pathway.

Bladder cancer is one of the most malignant tumors closely associated with macrophages. Polyporus polysaccharide (PPS) has shown excellent efficacy in treating bladder cancer with minimal side effects. However, the molecular mechanisms underlying the effects of PPS in inhibiting bladder cancer remain unclear. In this study, we used macrophages cultured alone or with T24 human bladder cancer cell culture supernatant as study models. We found that PPS enhanced the activities of IFN-γ-stimulated RAW 264.7 macrophages, as shown by the release of inducible nitric oxide synthase (INOS), secretion of tumor necrosis factor (TNF)-α and interleukin (IL)-6, phagocytosis activity, as well as expression of M1 phenotype indicators, such as CD40, CD284 and CD86. PPS acted upstream in activation cascade of nuclear factor (NF)-κB signaling pathways by interfering with IκB phosphorylation. In addition, PPS regulated NF-κB (P65) signaling by interfering with Toll-like receptor (TLR)-4, INOS and cyclooxygenase (COX)-2. Our results indicate that PPS activates macrophages through TLR4/NF-κB signaling pathways.

Paeonia ostii is a traditional ornamental and medicinal species that has attracted considerable interest for its high oil value. To facilitate the effective and rational cultivation and application of P . ostii in China, it is necessary to determine its potential spatial habitat distribution and environmental requirements. Using high-resolution environmental data for current and future climate scenarios, the potential suitable area and climatic requirements of P . ostii were modelled. Among the 11 environmental variables investigated, growing degree days, precipitation of the wettest month, mean temperature of the coldest quarter, global UV-B radiation, annual precipitation, and soil pH played major roles in determining the suitability of a habitat for the cultivation of P . ostii . Under the current environmental conditions in China, a total area of 20.31 × 10 5  km 2 is suitable for growing P . ostii , accounting for 21.16% of the country’s total land area. Under the two future climate scenario/year combinations (i.e., representative concentration pathways [RCPs], RCP2.6 and RCP8.5 in 2050), this species would increase its suitable area at high latitudes while decrease at low latitudes. These results present valuable information and a theoretical reference point for identifying the suitable cultivation areas of P . ostii .

• Arginine rich, mutated in early stage of tumours (Armet), is a well-characterized bifunctional protein as an unfolded protein response component intracellularly and a neurotrophic factor extracellularly in mammals. Recently, a new role of Armet as an effector protein mediating insect–plant interactions has been reported; however, its molecular mechanisms underlying the regulation of plant defences remain unclear. • We investigated the molecular mechanisms underlying whitefly-secreted Armet-mediated regulation of insect–plant interaction by agrobacterium-mediated transient expression, RNA interference, electrical penetration graph, protein–protein interaction studies, virus-induced gene silencing assay, phytohormone analysis and whitefly bioassays. • Armet, secreted by Bemisia tabaci whitefly, is highly expressed in the primary salivary gland and is delivered into tobacco plants during feeding. Overexpression of the BtArmet gene in tobacco enhanced whitefly performance, while silencing the BtArmet gene in whitefly interrupted whitefly feeding and suppressed whitefly performance on tobacco plants. BtArmet was shown to interact with NtCYS6, a cystatin protein essential for tobacco anti-whitefly resistance, and counteract the negative effects of NtCYS6 on whitefly. • These results indicate that BtArmet is a salivary effector and acts to promote whitefly performance on tobacco plants through binding to the tobacco cystatin NtCYS6. Our findings provide novel insight into whitefly–plant interactions.

Multiferroics have been investigated extensively in the last decades due to their wide range of applications in high‐density multistate storage, spintronics, and novel multifunctional magnetic–electric devices. One peculiar subgroup of multiferroic materials comprises 3D perovskite metal–organic frameworks (MOFs) with the general formula ABX3 (A = monovalent organic cation (such as an alkali metal or protonated amine), B = divalent metal cation, X = organic anion), for their coexistence of multiple orders (electric, magnetic, and elastic, et al.). The purpose of this review is to give a representative overview of the recent progress in the field of ABX3‐type multiferroic MOFs, containing 3d magnetic metal ions at B‐site. First, the perovskite multiferroic MOFs in which X‐site is occupied by formate, is examined and summarized. In particular, magnetoelectric coupling effects, such as electric‐field tuning of magnetic properties and magnetic field control of electric polarization, and pressure control of structural/magnetic/electric properties, are described and discussed. Then, it is focused on the structural phase transitions and ferroic orders by analyzing several representative multiferroic MOFs compounds with none‐formate. To motivate the researchers in this area, some promising topics that have not yet been fully explored in perovskite multiferroic MOFs are finally proposed. This review gives a representative overview of the recent progress in the field of ABX3‐type multiferroic MOFs, containing 3d magnetic metal ions at B‐site. The image represents the multiple ferroic orders and their mutual cross‐couplings in multiferroics, as well as the corresponding mechanisms of several representative orders in multiferroic MOFs.

The escalating global prevalence of carbapenem-resistant Gram-negative bacteria has significantly constrained therapeutic options, leading to the revived use of polymyxins. However, this resurgence has been paralleled by an increase in reports of associated adverse effects. No case of drug fever induced by polymyxin B (PMB) has been reported in the literature to date. We report the first case of drug fever (≥39 °C) induced by intravenous PMB in a patient with severe pneumonia caused by carbapenem-resistant , accompanied by tachypnea following concomitant nebulized PMB administration. Upon intervention by the clinical pharmacist, which involved discontinuation of PMB and adjustment of the anti-infective regimen, the patient's fever resolved promptly and the infection was successfully controlled. This case highlights a severe and previously unreported adverse drug reaction to PMB, underscoring the necessity for vigilant monitoring and proactive antimicrobial stewardship in managing infections.

The primary processed product of Panax ginseng C.A. Meyer ( P. ginseng ) is red ginseng. As technology advances, new products of red ginseng have arisen. Red ginseng products, e.g., traditional red ginseng, sun ginseng, black ginseng, fermented red ginseng, and puffed red ginseng, are commonly used in herbal medicine. Ginsenosides are the major secondary metabolites of P. ginseng . The constituents of P. ginseng are significantly changed during processing, and several pharmacological activities of red ginseng products are dramatically increased compared to white ginseng. In this paper, we aimed to review the ginsenosides and pharmacological activities of various red ginseng products, the transformation law of ginsenosides in processing, and some clinical trials of red ginseng products. This article will help to highlight the diverse pharmacological properties of red ginseng products and aid in the future development of red ginseng industrialization.

In this study, a novel adsorbent (SRM-ZnO) was prepared using zinc oxide supported on red mud in a seawater medium and was used for the adsorption of methyl orange (MO). It is expected to solve the recycling of red mud and prepare an economical adsorbent with high efficiency to adsorb dye wastewater. Material composition and morphology analyses showed that hydrotalcite compounds were attached on the surface of SRM-ZnO. The hydrotalcite compounds can increase the surface area of the modified red mud and thus increase the adsorption capacity of MO. The adsorption of MO dye on modified red mud conforms to the Temkin isotherm model and pseudo-second-order kinetic model. The adsorption behavior mainly includes physical interaction, supplemented with chemical interactions. Result also found that the adsorption of MO on SRM-ZnO is a spontaneous exothermic process.

There is a scarcity of scholarship that sheds light on international doctoral students' identity construction in quotidian encounters beyond the formal curriculum. In this autoethnographic study, based on my diary entries, via a socio- constructivist lens, I teased out my multidimensional identity construction by referring to situations, activities and relations embedded in daily experiences during my overseas study sojourn. My autoethnography reveals that how I make sense of my becoming and being as a Chinese sojourning in Australia for doctoral education transcends the experientiality of doing research alone, but incorporates gendered, sociocultural and professional facets within my past-present- future life trajectory. As I navigated these encounters, strategically mobilising my agency and utilising structural contexts towards the aim of achieving ontological security, I engaged in negotiating a transformative identity. The research calls for more studies in the future that explore the complexities and nuances of international doctoral students' identity construction in quotidian realities. [Author abstract]
