The multifunctional role of phosphodiesterase 5 inhibitors in medicine

Insect antennae are sensory organs of great importance because they can sense diverse environmental stimuli. In addition to serving as primary olfactory organs of insects, antennae also sense a wide variety of mechanosensory stimuli, ranging from low-frequency airflow or gravity cues to high-frequency antennal vibrations due to sound, flight or touch. The basal segments of the antennae house multiple types of mechanosensory structures that prominently include the sensory hair plates, or Böhm's bristles, which measure the gross extent of antennal movement, and a ring of highly sensitive scolopidial neurons, collectively called the Johnston's organs, which record subtle flagellar vibrations. To fulfill their multifunctional mechanosensory role, the antennae of insects must actively move thereby enhancing their ability to sense various cues in the surrounding environment. This tight coupling between antennal mechanosensory function and antennal movements means that the underlying mechanosensory-motor apparatus constitutes a highly tuned feedback-controlled system. Our study aims to explore how the sensory and motor components of this system are configured to enable such functional versatility. We describe antennal mechanosensory neurons, their central projections in the brain relative to antennal motor neurons and the internal morphology of various antennal muscles that actuate the basal segments of the antenna. We studied these in the Oleander hawk moth (Daphnis nerii) using a combination of techniques such as neural dye fills, confocal microscopy, scanning electron microscopy and X-ray tomography. Our study thus provides a detailed anatomical picture of the antennal mechanosensory-motor apparatus, which in turn provides key insights into its multifunctional role.

Internalizing the value of biodiversity has been discussed in the Post-2020 Global Biodiversity Framework. The importance of capturing values of biodiversity in policy-making among various actors is frequently emphasized through the implementation of Ecosystem Services economic Valuation (ESV). However, ESV-related studies focusing on the policy-evaluation interface are still limited. This study contributes to this knowledge gap by analyzing the use of ESV in policy making in the case of forests’ multi-function roles at the national and sub-national levels in Japan. This work carried out document surveys, phone interviews, statistical analysis, and framework analysis. Results showed that ESVs in Japan were implemented in 34 (72%) prefectures (sub-national level) and four times at the national level. Most of these ESVs have not been updated for over 20 years. In addition, the ESVs were mainly used as an “Informative” type in both levels. These findings indicated that ESVs of macro-level forests were rarely utilized in a specific policy and updating them were not a necessity in implementing forest policies. Furthermore, results of the Pearson’s chi-squared test showed that no significant differences (p < 0.05) were observed when (1) the average values of prefectural indicators related to forests between the two groups (“prefectures with ESVs” and “prefectures without ESVs”) were compared and (2) relevancies and magnitude of those indicators were analyzed, suggesting that the presence or absence of ESV can be driven other factors such as the administrative organization. The results of this work can be used to further understand and illustrate the essential role of ESV implementation in drafting frameworks and/or policies for forest ecosystems management.

The study consists of the following three steps: 1. The correlations between the recognitions for the multifunctional roles and the awareness of the environments. 2. The value of the multifunctional roles of fisheries and fishery communities are estimated with the Contingent Valuation Method (CVM). 3. The research on the role to provide communication spaces between the urban and rural areas among the multifunctional roles are deepened.

Role of human milk components in gastrointestinal development: Current knowledge and future NEEDS

Indonesia is renowned as an agricultural powerhouse, ranking first globally in oil palm production. This prominence in agriculture leads to the consistent generation of agro-industrial waste, notably Palm Oil Mill Effluent (POME). Effectively addressing these waste concerns is important due to their adverse impacts on aquatic ecosystems and the nation’s health and economy. Anthropogenic wastewater with excessive phosphorus content can trigger eutrophication and toxic algal blooms, posing environmental risks and potentially precipitating a future clean water crisis. Thus, a comprehensive approach is necessary to restore the environment and biogeochemical cycles. Treatment efforts involving bioremediation agents aim to recycle organic and inorganic pollutants in the environment. Photosynthetic organisms like plants and microalgae serve as effective bioremediation agents, capable of absorbing excess phosphorus. They can utilize phosphate as an energy source to boost biomass. Integrating these bioremediation agents with bioengineering technology optimizes the treatment efficacy while simultaneously producing valuable biomass for products and bioenergy. This review article explores photosynthetic organisms’ multifunctional role as phosphorus bioremediation agents for wastewater treatment, minimizing environmental pollutant impacts, and providing biomass for fertilizers, polymers, bioplastics, and renewable energy. Furthermore, this study unveils opportunities for future technological advancements in this field.

Creditable bonds’ multifunctional roles during the COVID-19 pandemic

Human milk oligosaccharides (HMOs), the third most abundant solid component in human milk, vary significantly among women due to factors such as secretor status, race, geography, season, maternal nutrition and weight, gestational age, and delivery method. In recent studies, HMOs have been shown to have a variety of functional roles in the development of infants. Because HMOs are not digested by infants, they act as metabolic substrates for certain bacteria, helping to establish the infant's gut microbiota. By encouraging the growth of advantageous intestinal bacteria, these sugars function as prebiotics and produce short-chain fatty acids (SCFAs), which are essential for gut health. HMOs can also specifically reduce harmful microbes and viruses binding to the gut epithelium, preventing illness. HMO addition to infant formula is safe and promotes healthy development, infection prevention, and microbiota. Current infant formulas frequently contain oligosaccharides (OSs) that differ structurally from those found in human milk, making it unlikely that they would reproduce the unique effects of HMOs. However, there is a growing trend in producing OSs resembling HMOs, but limited data make it unclear whether HMOs offer additional therapeutic benefits compared to non-human OSs. Better knowledge of how the human mammary gland synthesizes HMOs could direct the development of technologies that yield a broad variety of complex HMOs with OS compositions that closely mimic human milk. This review explores HMOs' complex nature and vital role in infant health, examining maternal variation in HMO composition and its contributing factors. It highlights recent technological advances enabling large-scale studies on HMO composition and its effects on infant health. Furthermore, HMOs' multifunctional roles in biological processes such as infection prevention, brain development, and gut microbiota and immune response regulation are investigated. The structural distinctions between HMOs and other mammalian OSs in infant formulas are discussed, with a focus on the trend toward producing more precise replicas of HMOs found in human milk.

Finally, it addresses key challenges and proposes future research directions in this evolving field.

Insect cuticle has drawn a lot of attention from engineers because of its multifunctional role in the life of insects. Some of these cuticles have an optimal combination of lightweight and good mechanical properties, and have inspired the design of composites with novel microstructures. Among these, beetle elytra have been explored extensively for their multilayered structure, multifunctional roles and mechanical properties. In this study, we investigated the bending properties of elytra by simulating their natural loading condition and comparing it with other loading configurations. Further, we examined the properties of their constitutive bulk layers to understand the contribution of each one to the overall mechanical behaviour. Our results showed that elytra are graded, multilayered composite structures that perform better in natural loading direction in terms of both flexural modulus and strength which is likely an adaptation to withstand loads encountered in the habitat. Experiments are supported by analytical calculations and finite element method modelling, which highlighted the additional role of the relatively stiff external exocuticle and of the flexible thin bottom layer in enhancing flexural mechanical properties. Such studies contribute to the knowledge of the mechanical behaviour of this natural composite material and to the development of novel bioinspired multifunctional composites and for optimized armours.

Bacteria have highly flexible pangenomes, which are thought to facilitate evolutionary responses to environmental change, but the impacts of environmental stress on pangenome evolution remain unclear. Using a landscape pangenomics approach, I demonstrate that environmental stress leads to consistent, continuous reduction in genome content along four environmental stress gradients (acidity, aridity, heat, salinity) in naturally occurring populations of Bradyrhizobium diazoefficiens (widespread soil-dwelling plant mutualists). Using gene-level network and duplication functional traits to predict accessory gene distributions across environments, genes predicted to be superfluous are more likely lost in high stress, while genes with multi-functional roles are more likely retained. Genes with higher probabilities of being lost with stress contain significantly higher proportions of codons under strong purifying and positive selection. Gene loss is widespread across the entire genome, with high gene-retention hotspots in close spatial proximity to core genes, suggesting Bradyrhizobium has evolved to cluster essential-function genes (accessory genes with multifunctional roles and core genes) in discrete genomic regions, which may stabilise viability during genomic decay. In conclusion, pangenome evolution through genome streamlining are important evolutionary responses to environmental change. This raises questions about impacts of genome streamlining on the adaptive capacity of bacterial populations facing rapid environmental change.

PurposeThe aim of this study is to systematise the entrepreneurial coaching (EC) literature by understanding how the phenomenon has been investigated along four dimensions inspired by Gartner’s (1985) conceptualisation of entrepreneurship: entrepreneurial process, context, target and outcomes. In so doing, this study will provide a frame of its multifunctional role and identify relevant gaps and suggestions for future research.Design/methodology/approachWe conducted a systematic literature review to collect existing works on EC. We analysed 85 selected papers with a qualitative content analysis that allowed us to highlight relevant research themes for the entrepreneurial process, context, outcomes and target.FindingsOur results demonstrate that EC has a multifunctional role in entrepreneurship that can be summarised in five different typologies, depending on the stage of the entrepreneurial process in which it is applied, the context, the target and the outcomes.Originality/valueAs one of the first attempts to systematise studies on EC, this work extends previous conceptualisation of EC by detailing different typologies of this intervention, thereby contributing to reduced fragmentation and conceptual ambiguity.

Leptin is a 16 kDa protein which consists of 167 amino acids. Leptin is considered as one of the adipokines, secreted by white adipocytes, and is the product of the obese (ob) gene. Recently, leptin is recognized as the immuno-stimulator which belongs to the same class of long chain helical cytokines such as interleukin (IL)-6. Leptin is related to the immune responses evoked by Mycobacterium tuberculosis infection. Thus, studies of association between immunomolecules including leptin and tuberculosis may contribute to provide an essential solution regulating adverse immune responses in several mycobacterial diseases. Leptin has a multifunctional role in the secretion of acute-phase cytokines including IL-1β and tumor-necrosis factor-alpha (TNF-α), and links to T helper 1 (Th1) immune response. Moreover, the binding of leptin to leptin receptor (LepR) is important in that this binding involves janus kinase/signal transducer and activator of transcription (JAK/STAT) pathway. In addition, the activation of LepR mediates extra-cellular signal-regulated kinase(ERK) and phosphoinositide 3 kinase (PI3K) pathways. Furthermore, many studies suggest that leptin may play a critical role in respiratory diseases including chronic obstructive pulmonary disease (COPD) and asthma as well as tuberculosis. These findings indicate that leptin is one of the important regulators for immune responses in respiratory diseases. We herein discuss the multifunctional role of leptin in mycobacterial lung disease, especially focusing on the related pathway to immune responses.

Borrelia burgdorferi is the causative agent of Lyme disease in the U.S., with at least 25,000 cases reported to the CDC each year. B. burgdorferi is thought to enter and exit the bloodstream to achieve rapid dissemination to distal tissue sites during infection. Travel through the bloodstream requires evasion of immune surveillance and pathogen clearance in the host, a process at which B. burgdorferi is adept. B. burgdorferi encodes greater than 19 adhesive outer surface proteins many of which have been found to bind to host cells or components of the extracellular matrix. Several others bind to host complement regulatory factors, in vitro. Production of many of these adhesive proteins is tightly regulated by environmental cues, and some have been shown to aid in vascular interactions and tissue colonization, as well as survival in the blood, in vivo. Recent work has described multifaceted and redundant roles of B. burgdorferi outer surface proteins in complement component interactions and tissue targeted adhesion and colonization, distinct from their previously identified in vitro binding capabilities. Recent insights into the multifunctional roles of previously well-characterized outer surface proteins such as BBK32, DbpA, CspA, and OspC have changed the way we think about the surface proteome of these organisms during the tick–mammal life cycle. With the combination of new and old in vivo models and in vitro techniques, the field has identified distinct ligand binding domains on BBK32 and DbpA that afford tissue colonization or blood survival to B. burgdorferi. In this review, we describe the multifunctional and redundant roles of many adhesive outer surface proteins of B. burgdorferi in tissue adhesion, colonization, and bloodstream survival that, together, promote the survival of Borrelia spp. throughout maintenance in their multi-host lifestyle.
