Ultra-stable panchromatic luminescent BaMoO/CsPbX (X = Cl, Br, I) heterostructures by suppressing interfacial charge transfer.

Constructing perovskite heterostructures with restricted interface charge transfer is crucial for improving stability and optoelectronic performance, as well as expanding multifunctional applications. Herein, a one-step solvent-free thermal assisted epitaxial growth strategy is proposed to construct BaMoO/CsPbX (X = Cl, Br, I) heterostructures. Derived from the high lattice matching of 90.

Bee fear responses are mediated by dopamine and influence cognition.

Predatory threats, even when they do not involve direct consumption (non-consumptive effects, NCEs), can profoundly influence the physiology and behaviour of prey. For example, honeybees that encounter hornet predators show responses similar to fear. However, the physiological mechanisms that are connected with this fear-like response and their effects on bee cognition and olfaction remain largely unknown.

Identification of characteristic flavor compounds of from different regions based on by -nose, HS-GC-IMS and HS-SPME-GC-MS.

In this study, -nose, HS-GC-IMS, and HS-SPME-GC-MS technologies were used to evaluate the flavor characteristics of the pileus and stipe of from eight origins. 23 key Volatile organic compounds (VOCs) with odor activity values (OAVs) > 1 were identified, and 19 aroma types have been identified in at the same time. Vegetable and earthy were defined as the dominant aroma types for all pileus and stipe samples.

A Method for Studying Social Signal Learning of the Waggle Dance in Honey Bees.

Honey bees use a complex form of spatial referential communication. Their waggle dance communicates to nestmates the direction, distance, and quality of a resource by encoding celestial cues, retinal optic flow, and relative food value into motion and sound within the nest. This protocol was developed to investigate the potential for social learning of this waggle dance.

An inhibitory signal associated with danger reduces honeybee dopamine levels.

Positive and negative experiences can alter animal brain dopamine levels. When first arriving at a rewarding food source or beginning to waggle dance and recruit nestmates to food, honeybees have increased brain dopamine levels, indicating a desire for food. We provide the first evidence that an inhibitory signal, the stop signal, which counters waggle dancing and is triggered by negative events at the food source, can decrease head dopamine levels and dancing, independent of the dancer having any negative experiences.

Social signal learning of the waggle dance in honey bees.

Honey bees use a complex form of spatial referential communication. Their "waggle dance" communicates the direction, distance, and quality of a resource to nestmates by encoding celestial cues, retinal optic flow, and relative food value into motion and sound within the nest. We show that correct waggle dancing requires social learning.

Surface and back-side defects identification combined with magnetic flux leakage and boundary magnetic perturbation.

In magnetic flux leakage (MFL) detection, the identification of surface and back-side defects is required to obtain more accurate defect quantification and risk assessment results. However, current MFL techniques can detect both surface and back-side defects but are generally unable to distinguish between them. Therefore, this paper proposes a new boundary magnetic perturbation (BMP) testing method, combining the results of MFL to distinguish between surface and back-side defects.

Identification of giant hornet Vespa mandarinia queen sex pheromone components.

The Vespidae is a diverse family of wasps and hornets that are formidable predators of insects, including social bees, and includes a number of invasive species. Recently, the world's largest hornet, Vespa mandarinia Smith (Hymenoptera: Vespidae), which occurs naturally in the Indomalayan region, has been found in Canada and the United States. Some simulations indicate that it could rapidly spread throughout Washington and Oregon in the western US, as well as some eastern parts of the country, threaten native bees and honeybees, and harm bee-pollinated crop production worth over $100 million annually.

Lethality of Honey Bee Stings to Heavily Armored Hornets.

The heat ball defense of honey bees against their sympatric hornet predators is a classic and spectacular outcome of a co-evolutionary race. Hundreds of bees can encapsulate a hornet within a large ball that kills it with elevated heat. However, the role of stinging in this defense has been discounted, even though sting venom is an important weapon in bees.

Early rehabilitation after lung transplantation with extracorporeal membrane oxygenation (ECMO) of COVID-19 patient: a case report.

Even when severe acute respiratory syndrome coronavirus 2-related coronavirus disease 2019 (COVID-19) is treated with first-line drugs, it progresses and leads to irreversible loss of lung function in some critically ill patients, and lung transplantation is an effective treatment for end-stage chronic pulmonary disease. This case report mainly describes the rehabilitation of a 66-year-old female patient with severe COVID-19 after bilateral lung transplantation. The old patient had a body mass index of 31.

The Nasonov gland pheromone as a potential source of death cue in Apis cerana.

The ability to detect and remove dead adult bees is an essential part of honeybee colony fitness that prevents the spread of pathogens. Fatty acid olfactory cues stimulate undertaking behavior among different social species within Hymenoptera, but the chemicals responsible for the death cue in Apis cerana have not yet been identified. We explored the Nasonov gland as a potential source of these chemicals in A.

Floral tea polyphenols can improve honey bee memory retention and olfactory sensitivity.

Animal-pollinated plants face a common problem, how their defensive anti-herbivore compounds may impair or alter pollinator behavior. Evolution has tailored multiple solutions, which largely involve pollinator tolerance or manipulation, to the benefit of the plant, not the removal of these compounds from pollen or nectar. The tea plant, Camilla sinensis, is famous for the caffeine and tea polyphenols (TP) that it produces in its leaves.

Visual contagion in prey defence signals can enhance honest defence.

The co-evolutionary arms race between predators and their prey has led to complex signalling, especially in groups that benefit from the social transmission of alarm signals. In particular, pursuit deterrence signals can allow individuals and groups to indicate, at relatively low cost, that a predator's further approach is futile. Pursuit deterrence signals are usually more effective if amplified, for example, by becoming contagious and rapidly spreading among prey without requiring individual prey to confirm predator presence.

[Source Apportionment and Heath Risk Quantification of Heavy Metals in PM in Yangzhou, China].

Recently, a new method combining positive matrix factorization (PMF) and heavy metal health risk (HMHR) assessment was proposed to apportion sources of heavy metals in ambient particulate matter and the associated heavy metal cancer health risk (HMCR), which has been applied to data collected in Yangzhou, China. The annual average concentrations of six measured heavy metals were Pb (64.4 ng·m), followed by Cr (25.

PIK3CD induces cell growth and invasion by activating AKT/GSK-3β/β-catenin signaling in colorectal cancer.

The catalytic subunit p110δ of phosphoinositide 3-kinase (PI3K) encoded by PIK3CD has been implicated in some human solid tumors. However, its roles in colorectal cancer (CRC) remain largely unknown. Here we found that PIK3CD was overexpressed in colon cancer tissues and CRC cell lines and was an independent predictor for overall survival (OS) of patients with colon cancer.

Interval colorectal cancer: a challenging field in colorectal cancer.

Accumulated evidence has shown that colonoscopy may not be a perfect tool in screening and reducing the incidence of the colorectal cancer (CRC), because interval CRC (I-CRC), a specific subgroup of CRCs, has been challenging the traditional detection technology in recent years. I-CRC is accounting for an increasing proportion in CRCs. However, the effective procedures to prevent and supervise I-CRC need to be explored.

The pesticide flupyradifurone impairs olfactory learning in Asian honey bees (Apis cerana) exposed as larvae or as adults.

Relatively little attention has focused on how pesticides may affect Asian honey bees, which provide vital crop pollination services and are key native pollinators. We therefore studied the effects of a relatively new pesticide, flupyradifurone (FLU), which has been developed, in part, because it appears safer for honey bees than neonicotinoids. We tested the effects of FLU on Apis cerana olfactory learning in larvae (lower dose of 0.

The sex pheromone of a globally invasive honey bee predator, the Asian eusocial hornet, Vespa velutina.

The Asian hornet, Vespa velutina, is an invasive, globally-distributed predator of European honey bees and other insects. To better under its reproductive biology and to find a specific, effective, and low-impact control method for this species, we identified and tested the key compounds in V. velutina sex pheromone.

Corrigendum: Resisting majesty: Apis cerana, has lower antennal sensitivity and decreased attraction to queen mandibular pheromone than Apis mellifera.

This corrects the article DOI: 10.1038/srep44640.

The dynamic association between ovariole loss and sterility in adult honeybee workers.

In the social insects, ovary state (the presence or absence of mature oocytes) and ovary size (the number of ovarioles) are often used as proxies for the reproductive capacity of an individual worker. Ovary size is assumed to be fixed post-eclosion whereas ovary state is demonstrably plastic post-eclosion. Here, we show that in fact ovary size declines as honeybee workers age.

Resisting majesty: Apis cerana, has lower antennal sensitivity and decreased attraction to queen mandibular pheromone than Apis mellifera.

In highly social bees, queen mandibular pheromone (QMP) is vital for colony life. Both Apis cerana (Ac) and Apis mellifera (Am) share an evolutionarily conserved set of QMP compounds: (E)-9-oxodec-2-enoic acid (9-ODA), (E)-9-hydroxydec-2-enoic acid (9-HDA), (E)-10-hydroxy-dec-2-enoic acid (10-HDA), 10-hydroxy-decanoic acid (10-HDAA), and methyl p-hydroxybenzoate (HOB) found at similar levels. However, evidence suggests there may be species-specific sensitivity differences to QMP compounds because Ac workers have higher levels of ovarian activation than Am workers.

Poison and alarm: the Asian hornet uses sting venom volatiles as an alarm pheromone.

In colonial organisms, alarm pheromones can provide a key fitness advantage by enhancing colony defence and warning of danger. Learning which species use alarm pheromone and the key compounds involved therefore enhances our understanding of how this important signal has evolved. However, our knowledge of alarm pheromones is more limited in the social wasps and hornets compared with the social bees and ants.

[Research progress of serrated polyposis syndrome].

Serrated polyposis syndrome (SPS) is closely associated with the initiation and development of colorectal cancer (CRC), however, there is few research on SPS in China. Serrated polyps can be divided into hyperplastic polyps, sessile serrated polyps and traditional serrated polyps. The diagnosis standard of SPS is as following: (1) There are at least 5 serrated lesions in proximal colon, and diameter of more than 2 lesions is >10 mm; (2) The patient has one serrated polyp with family history of SPS; (3) More than 20 serrated polyps can be found in the entire large bowel.
