Consciousness is one of final questions for humans to tackle in neuroscience. Due to the lack of understanding of the basic brain network and mechanisms of functions, our knowledge of consciousness remains at the theoretical level. Recent studies using brain imaging in humans and modern neuroscience techniques in animal studies reveal a basic brain network for consciousness. The projection from the thalamus to different cortical regions form a network of activities to maintain consciousness in human and animals. These feedback and feedforward circuits maintain the consciousness even in certain brain injury conditions. Proteins and ion channels that contribute to these circuit neural activities are targets for drugs and manipulations that affect consciousness, such as anesthetic agents. Synaptic plasticity that trains synapses during learning and information recall, modify circuits and contribute to a high level of consciousness in certain populations.

lzheimer’s disease is a major cause of death among elderly patients and is characterized by beta-amyloid plaques and neurofibrillary tangles. The current treatment methods have been ineffective, but recent advancements in transcranial current stimulation have shown positive effects on memory and cognition in patients with mild cognitive impairment (MCI) due to Alzheimer’s disease. Transcranial current stimulation involves the application of electrical current at specific frequencies to various brain regions, with two distinct types: direct current stimulation (tDCS) and alternating current stimulation (tACS). This paper aims to compare the effectiveness of tDCS and tACS in treating MCI. A structured systematic review was conducted on 33 articles from various databases, which included randomized, placebo, self-reported, motivational, comparative, and literature review studies published within the last 10 years. Data analysis involved calculating statistical significance and effect sizes (Cohen’s d) for specific treatment modalities and outcome measures. The results highlight the potential of both tACS and tDCS as non-invasive treatment options for MCI in AD. Further research with larger sample sizes, standardized protocols, and longer-term follow-ups is needed to establish a clear superiority between the two techniques. Nonetheless, tACS and tDCS interventions hold promise in improving the quality of life for individuals with Alzheimer’s disease. While both interventions showed promising results, the review suggests that tACS exhibits more favorable outcomes in certain cognitive domains compared to tDCS. To establish a clear superiority between tDCS and tACS, further research involving larger sample sizes, standardized protocols, and longer-term follow-ups is necessary.

Parvalbumin-positive interneurons (PV-INs) and Somatostatin-positive interneurons (SST-INs) have emerged as key players in regulating network activity and plasticity in both healthy and diseased states. In particular, research has highlighted the involvement of interneurons in the development of various psychiatric disorders. We previously showed that TrkB activity in PV-INs plays a central role in the regulation of neuronal plasticity. This study investigates the role of TrkB in PV and SST interneurons and explores the validity of an interneuron-specific TrkB knockout mouse model. Mice with reduced TrkB expression in either PV-INs or SST-INs were generated to simulate an abnormal but not completely absent BDNF/TrkB pathway. By conducting behavioural battery, we observed that mice with impaired TrkB expression PV-INs exhibited a significant deficit in the Prepulse inhibition test (PPI), indicating altered sensorimotor gating. Conversely, TrkB knockout in SST-INs resulted in an opposite enhanced PPI effect, as well as a significantly shorter latency to enter the open arm in the elevated plus maze test, suggesting altered decision-making behaviour. These findings provide insights into the involvement of the BDNF/TrkB pathway in PV-INs and SST-INs, supporting the use of heterozygous TrkB knockout models in studying interneuron plasticity and network dynamics. Moreover, the altered sensorimotor gating observed in PV-INs highlights the potential of this model in understanding the sensorimotor abnormalities observed in schizophrenia.

The involvement of inwardly rectifying potassium channel 4.1 (Kir4.1) in neuropathic pain has been established. However, there is limited understanding of the downstream mechanism through which Kir4.1 contributes to orofacial neuropathic pain. The objective of this study was to examine the regulation of Kir4.1 on the expression of pannexin 3 (Panx3) in the trigeminal ganglion (TG) and the underlying mechanism in the context of orofacial neuropathic pain caused by chronic constriction injury of the infraorbital nerve (CCI-ION). The study observed a significant increase in Panx3 expression in the TG of mice with CCI-ION. Inhibition of Panx3 in the TG of CCI-ION mice resulted in alleviation of orofacial mechanical allodynia. Furthermore, conditional knockdown (CKD) of Kir4.1 in the TG of both male and female mice led to mechanical allodynia and up-regulation of Panx3 expression. Conversely, overexpression of Kir4.1 decreased Panx3 levels in the TG and relieved mechanical allodynia in CCI-ION mice. In addition, silencing Kir4.1 in satellite glial cells (SGCs) decreased Panx3 expression and increased the phosphorylation of P38 MAPK. Moreover, silencing Kir4.1 in SGCs increased the levels of reactive oxygen species (ROS). The elevated phosphorylation of P38 MAPK resulting from Kir4.1 silencing was inhibited by using a superoxide scavenger known as the tempol. Silencing Panx3 in the TG in vivo attenuated the mechanical allodynia caused by Kir4.1 CKD. In conclusion, these findings suggest that the reduction of Kir4.1 promotes the expression of Panx3 by activating the ROS-P38 MAPK signaling pathway, thus contributing to the development of orofacial neuropathic pain.

Background: Increasing evidence are available about the presence of increased serum concentration of Immunoglobulin (Ig) Free Light Chains (FLCs) in both atopic and non-atopic inflammatory diseases, including severe asthma, providing a possible new biomarker of disease, disease severity and also an alternative approach to the treatment. Methods: We analyzed clinical and laboratory data, including FLCs, obtained from a cohort of 79 asthmatic subjects, clinically classified into different GINA steps. A control group of 40 age-matched healthy donors (HD) was considered. Particularly, HD have been selected according to the absence of monoclonal components (in order to exclude paraproteinemias), were tested for total IgE (that were in the normal ranges) and were negative for aeroallergens specific IgE. Moreover, no abnormality of common inflammatory markers (i.e. erythrocyte sedimentation rate, C-reactive protein) was detectable. Results: FLC-k levels were significantly increased in the asthmatic population, compared to the control group. Despite the absence of statistically significant differences in FLC-λ levels, the FLC-k/FLC-λ ratio displayed remarkable differences between the two groups. A positive correlation between FLC-κ and FLC-λ levels was found. FLC- λ level displayed a significant negative correlation with the FEV1 value. Moreover, the FLC-κ /FLC- λ ratio was negatively correlated with the SNOT-22 score and a positive correlation was observed between FLCs and Staphylococcus Aureus IgE enterotoxins sensitization. Conclusions: Our findings confirmed the role of FLCs in asthma as a potential biomarker in an inflammatory disease characterized by different endotypes and phenotypes. In particular, FLC-κ and FLC-k/FLC-λ ratio could be a qualitative indicator for asthma, while FLC-λ levels could be a quantitative indicator for disease severity.

Background There is evidence to suggest that many medicines commonly used for pregnant women for the management of hypertensive disorders of pregnancy are poor quality. Objective To review the available studies systematically reporting medicine quality, routinely used in the prevention and management of hypertensive disorders of pregnancy. Search strategy We searched five electronic databases- Ovid MEDLINE, EMBASE, CINAHL, ProQuest and Cochrane Library, without year or language limitations. Selection criteria Studies reporting on quality parameters of nine medicines - magnesium sulphate, aspirin, calcium supplements, amlodipine, nifedipine, methyldopa, enalapril, hydralazine and labetalol, using any valid laboratory methods. Data collection and analysis Two reviewers independently screened the studies, extracted data and assessed the quality. Results were reported narratively by type of medicine. Main results Of 5669 citations screened, 33 studies from 27 countries were included. Five quality studies on magnesium sulphate- two (Nigeria and USA) found substandard medicine due to failing API specification and contaminants, respectively. Another study from Nigeria and a multi-country study (10 lower-middle- and low-income countries) found poor-quality due to failing the pH criteria. Seven of eight studies evaluating aspirin found quality issues, including degraded medicines in five studies (Brazil, USA, Yugoslavia and Pakistan). Five studies of calcium supplements found quality issues, particularly heavy metal contamination. Of 15 antihypertensives quality studies, 12 found substandard medicines and one study identified counterfeit medicines. Conclusion We identified multiple findings of poor quality across all types of medicines used in hypertensive disorders of pregnancy, raising concerns regarding their safety and effectiveness.

To both enhance the flexibility of the power system and absorption capacity of renewable energy connected to a grid and achieve the efficient use and cooperation of multi-side complex type energy storage resources on the source, grid, and load sides, a collaborative optimal scheduling system architecture of source-grid-load-storage (SGLS) considering multiple energy storage types was constructed. Latin hypercube sampling and sample reduction based on k-medoids clustering were adopted to generate the SGLS scenarios, considering the emergency circumstances of the power system. The flexibility of the multi-scenario power system was evaluated, and the battery energy storage stations, pumped storage, and electric vehicles with sufficient capacity were configured on the source, grid, and load sides, respectively, to participate in the scheduling. A multi-scenario SGLS cooperative optimisation scheduling model that considers multiple energy storage capacity configuration types was constructed for economic and environmental protection. Based on data-driven, a multi-objective optimisation algorithm was proposed by using the Gaussian process regression algorithm and non-dominated sorting genetic algorithm II, combined with the manifold interpolation batch evolution mechanism. Finally, using actual regional power grid data for verification, the proposed strategy effectively reduces system operating cost, enhances energy storage battery life, and improves the renewable energy consumption capacity.

For many aquatic and semiaquatic mammal, amphibian and fish species, environmental DNA (eDNA) methods are employed to detect species distribution and to monitor their presence, but eDNA is much less employed for avian species. Here, we developed primers for the detection of true geese and swan species using eDNA and optimized a PCR protocol for eDNA. We selected taiga bean goose (Anser fabalis fabalis) as our focal (sub)species and sampled water from lakes, from which the presence of taiga bean goose was visually confirmed. We filtered the lake water and extracted eDNA. We also included field negative controls (sterile water) which were handled similarly as eDNA samples to control sterility of equipment. For testing if taiga bean goose DNA could be detected among DNA of other goose species, we similarly sampled eDNA from a zoo pond housing several Anatidae species. We were able to detect taiga bean goose DNA in all but one of the tested lakes, including the zoo pond. The primers developed are not species-specific, but rather specific for the genus Anser, due to close relatedness of Anser species. We also developed eDNA primers for Branta-species and Cygnus-species and tested these primers using the same samples. Canada goose (B. canadensis) and barnacle goose (B. leucopsis) DNA were only detected in the zoo pond (in which they were present), as the sampled natural lakes fall outside the range of these species. We detected whooper swan (C. cygnus) DNA in three lakes and the zoo pond (in which the species was present). The eDNA method presented here provides a potential means to monitor elusive goose species and to study the co-occurrence of large waterfowl.

Objective The objective of this study is to examine the relationship between Preoperative hepatic arterial blood supply coefficient (HAC) and portal vein blood supply coefficient (PVC), and their impact on progression-free survival (PFS) and overall survival (OS) following transcatheter arterial chemoembolization (TACE) for hepatocellular carcinoma (HCC). Methods A retrospective analysis was carried out on 113 patients who were diagnosed with HCC in our hospital and received TACE treatment. Furthermore, the perfusion-enhanced CT prior to the first TACE in each patient selected the tumor area from plain scan, arterial late stage, as well as the portal venous stage to measure the average CT value and calculate HAC and PVC. All patients received follow-up care through August 2022. Besides, the independent predictors of PFS and OS were acquired by COX regression analysis, and subsequently, the independent predictors and the correlation between PFS and OS were evaluated by the Log-rank test, and the survival curve was drawn by Kaplan-Meier. Results A total of 91 patients died, with a mortality rate of 80.5%, the median progression-free survival was 0.78 (0.23-2.13) years, and the median overall survival was 2.04 (1.22-3.98) years. Univariate and multivariate COX regression analysis demonstrated that HAC and vascular invasion were independent predictors of PFS and OS (P<0.05). By utilizing the optimal HAC cut-off value, HAC was divided into low HAC and high HAC groups, and the liver function grade and largest tumor diameter were statistically distinct between the two groups (both P<0.05). Conclusion Preoperative HAC and vascular invasion predict progression-free survival as well as overall survival after TACE of hepatocellular carcinoma. Furthermore, HCC with HAC ≥ 0.042 and preoperative vascular invasion by now demonstrated on imaging are particularly susceptible to progression after TACE and have a shorter overall survival time.

Background : Metaplastic Breast Cancer (MpBC) is an exceedingly rare entity, accounting for less than 1% of all malignant breast tumours. Predominantly triple-negative, they are notorious for their chemoresistance, high rates of recurrence and decreased disease-free survival (DFS). All this contributes significantly to BC mortality and results in poor prognostic implications. Limited evidence has led to a lacuna of specific treatment guidelines for this entity and hence remains an uncharted territory for clinicians. Case : We report a case of left-sided low-grade metaplastic triple negative T3N2aM0 BC treated with neoadjuvant chemotherapy, primary surgery, and adjuvant radiotherapy, presently in remission. Conclusion : Limited experience in management of this pathological entity warrants the need for more research on it, with a special focus on targeted therapy. Discussing possibilities of a tailored approach, rather than a one-size-fits-all approach may aid in paving the path for the future of MpBC treatment.

Plant-soil feedbacks influence plant quality and quantity for herbivores, and in some studies this influence has been shown to vary with plant functional group. To better assess the impact of plant-soil feedbacks and plant functional group on herbivores we conducted the first meta-analysis to test for an interaction between plant-soil feedbacks and herbivory, including effects on the magnitude and direction of feedbacks, herbivore consumption and herbivore growth. We identified 197 studies to address herbivore impacts on plant-soil feedbacks and 189 studies to address plant-soil impacts on herbivores. We calculated Hedge’s G values based on plant-soil feedback values (ratio of plant growth in home soils divided by away soils using the log transformed ratio of means) to assess three questions: 1) What is the plant-soil feedback value of plants exposed to herbivory or no herbivory? 2) What is the growth or biomass of herbivores feeding on plants exposed to home or away soils in plant-soil feedback studies? 3) How much plant tissue is consumed by herbivores on plants grown in home or away soils? We found an overall significant weak negative effect of herbivory on plant-soil feedbacks that varied by plant functional type. In legumes herbivory drove plant-soil feedbacks from positive to negative, but herbivory on forbs further decreased negative feedbacks. Herbivore consumption was generally greater on plants grown in away soils. However, herbivore consumption was greater in home soils conditioned by legumes but lower in home soils conditioned by forbs. Therefore, plant functional type determines the impact of conditioned soil on feedbacks, and herbivore consumption explains these results for legumes but not forbs.

ChatGPT Generated Literature Review: Quod Erat Demonstrandum or Ends Justifying the Means?Dear Editor,We would like to draw your attention to the increasing popularity of the generative artificial intelligence (AI) chatbot, ChatGPT (OpenAI, 2023), and its relationship with scientific literature. We have attempted to replicate two literature reviews recently published in Clinical Otolaryngology using ChatGPT, comparing results, conclusions and references.Lee et al. (2022): Posterior nasal neurectomy for intractable rhinitis: A systematic review, was assessed. ChatGPT’s conclusions generated with the same research questions were comparable. However, ChatGPT’s references were confabulated raising questions of provenance and quality.Cereceda-Monteoliva et al. (2021), reviewed sarcoidosis of the ear, nose, and throat. Again, identical research questions generated near-identical results, including numerical values for incidence, features, and management. One generated reference appeared to be ‘similar’ in terms of the author’s name, but the title and journal were entirely incorrect. Of the remaining four references provided by ChatGPT, only one was a recognisable article. Further investigation shows ChatGPT lacks access to research databases, raising doubts about the reliability of the conclusions it presents.It is interesting that ChatGPT should generate correct conclusions but with incorrect working. We are reminded of school mathematics,quad erat demonstrandum (Q.E.D.), and where incorrect working affords you no marks regardless of a correct answer.ChatGPT is a Large Language Model (LLM) AI. Fundamentally, it mimics human intelligence but does not replicate it. ChatGPT does this by analysing vast quantities of data to predict the next most likely word in an answer – erroneously exemplified by the generated references. A scientific literature review follows a superficially similar process, analysing data and outputting a most likely conclusion. Crucially, the latter involves higher-order evaluation and critical thought based on myriad factors that seem currently out of reach for ChatGPT in this specific use case. Readers familiar with Bloom’s Taxonomy of Cognition will identify its relevance here[1].Often literature review produces an already anticipated conclusion but provides some of the highest quality evidence to base medical practice. Therefore, with ChatGPT, the ends do not justify the means for practiced medicine, even if the most likely worded conclusion is accurate.However, the exponential growth of LLM AIs is extraordinary. Near-future iterations of ChatGPT climbing to the top of Bloom’s Taxonomy are easily imagined. Improved critical reasoning with access to accurate databases of peer-reviewed material would substantiate an output, even if the conclusions are unchanged. An accurate ‘show of working’ could provide a meaningful AI-generated literature review to responsibly guide medical practice.Q.E.D. - Quod Erat DemonstrandumReferencesBloom, B.S.,Engelhart, M.

The three-dimensional rarity typology proposed by Rabinowitz in 1981, based on geographic range, habitat specificity, and local abundance, is among the most widely used frameworks for describing rarity in ecological and conservation research. While this framework is descriptive and is not meant to explain the causes of rarity, recent advances in ecology may be leveraged to add explanatory power. We propose a modification of Rabinowitz’s typology to better distinguish between the dimensions of rarity and the ecological processes that drive them, and explore the conservation implications of our modified framework. We suggest replacing habitat specificity with occupancy (the proportion of occupied sites within a species’ range), yielding a modified classification based on range size, occupancy, and local abundance. Habitat specificity remains embedded in our framework, but as a driver of rarity rather than a rarity axis. Under our framework, habitat specialists are no longer considered rare if they are widespread and abundant; we argue that this modification more accurately identifies truly rare species, as habitat specialists may be common if their habitat is abundant. Finally, we draw on the functional and theoretical literature to identify the key processes and associated traits that drive each rarity axis. In this respect, we identify four processes (environmental filtering, movement, demography, and interactions), and hypothesise that range size and occupancy are primarily driven by environmental filtering and movement, whereas local abundance is more strongly influenced by demography and interactions. We further use ecological theory to hypothesise the conservation concerns associated with each rarity axis, and propose conservation measures that may be suitable for conserving different types of rare species. Our work may provide a basis for developing hypotheses about the causes of rarity of particular focal taxa or groups, and inform the development of targeted conservation strategies.

China’s low nitrogen fertilizer use raises agricultural prices and environmental dangers. High-carbon fertilizer with biochar could help sequester carbon. High-carbon fertilizer was tested on roasted tobacco cultivation in Chenzhou. No-nitrogen fertilizer treatment assessed nitrogen consumption and economic benefits. Fertilizer-only and cake fertilizer treatments, substituting 13% and 26% of nitrogen with high carbon-based fertilizer, yielded the following results: Replacing 13% of N fertilizer with high-carbon fertilizer increased dry matter accumulation, utilization, agronomic efficiency, application efficiency, and production and investment ratios to 493.97 g-plant-1, 32.39%, 137.43 kg-kg-1, 65168.31 yuan-hm-2, and 8.97 yuan-yuan-1. 484.46 g-plant-1, 34.46%, 148.37 kg-kg-1, 72408.74 yuan-hm-2, and 8.04 yuan-yuan-1 at 26% replacement. High-carbon fertilizer boosted tobacco N fertilizer consumption and economic efficiency more than cake fertilizer. The 26% ratio of chemical fertilizer to organic fertilizer improved tobacco plant growth by improving nitrogen utilization. Using only chemical fertilizer nitrogen, roasted tobacco’s nitrogen distribution was 26%, 27%, 23%, and 24% in roots, stems, leaves, and flowers. Partial replacement with cake or high-carbon fertilizer boosted nitrogen distribution in roasted tobacco stems from 25% to 30%, slightly reducing in roots and leaves. The Chenzhou tobacco-rice rotation system optimizes nitrogen consumption and economic efficiency in roasted tobacco cultivation with high-carbon fertilizer. It outperforms cake fertilizer. A 26% ratio of organic nitrogen to chemical fertilizer outperforms a 13% ratio.

To evaluate seed quality and the fatty acids composition of peanut (Arachis hypogaea L.) influenced by the different forms of Zn and Ca based fertilizers, this experiment carried out as a split plot arrangement based on randomized complete block design with three replications in the Agricultural and Natural Resources Research and Education Center of Guilan, Rasht, Iran during the 2018 and 2019 cropping seasons. The four levels of the Zn fertilizers including without fertilizer application (control), Zn-chelated Nano-fertilizer (Zn- Nano), Zn-EDTA, Zn-sulfate (ZnSO4) as the main plot and the four levels of the Ca fertilizers including Ca-chelated Nano-fertilizer (Ca-Nano), Ca-EDTA, Ca-chloride (CaC) and Ca-nitrate (CaN) as the sub-plot, comprised experimental treatments. The greatest PNP (38.78), 100-SW (61.49 g), SY (2790 kg/ha), BY (9303 kg/ha), SOC (52.34 percent), OY (1625 kg/ha), PY (673 kg/ha), OA (57.30 %), and LA (30.97 %) were obtained in response to the simultaneous foliar application of Zn and Ca Nano-fertilizers. According to the results of this assessment, the combined application of the Nano forms of Zn and Ca based fertilizers enhanced the SY of peanut via increasing of PNP and 100-SW indices and improved the peanut oil quality due to the increment of unsaturated fatty acids such as OA and LA under regional climatic conditions. Hence, Zn and Ca Nano-fertilizers and showed superiority for the quantity and quality of peanut seed to the other forms of studied fertilizers and could be recommendable to enhance the quantitative and qualitative yield of peanut under similar climatic conditions.

Rising population growth rates, rapid urbanization and dynamic consumption patterns contribute to increased Municipal Solid Waste (MSW) generation in most municipalities across the globe, with ineffective management practices. This study assessed the energy potential of MSW in Techiman municipality of the Bono East region in Ghana and proposed suitable energy recovery technologies. Waste generated from 400 selected households were transported to a designated site, characterized and their energy content determined. Results from the study revealed that 66.5% of the waste generated in the Techiman municipality was organic, 19.2% was plastic, 3.3% was paper, 0.9% was glass, 3.2% was metals, 1.6% was leather and rubber, 0.6% was textiles, 1.9% was miscellaneous and 2.7% was inert. The moisture content of the major organic fractions of the waste ranged from 43.3% to 80.7%, whereas that of paper was found to be 5.8%. The high moisture content recorded supports biochemical conversion technologies, specifically anaerobic digestion and composting. From the estimation, plantain peels had the highest calorific value of 14.93 MJ/kg. This is followed by cassava peels with a value of 14.39 MJ/kg. The least calorific value was recorded in cocoyam peels as 7.65 MJ/kg. The total waste generated per day in the municipality was 194,668 kg. with the daily energy potential of the organic fraction of the generated waste estimated to be 1,574.94 GJ

Identifying genetic conservation units (CUs) in threatened species is critical for the preservation of adaptive capacity and evolutionary potential in the face of climate change. However, delineating CUs in highly mobile species remains a challenge due to high rates of gene flow and genetic signatures of isolation by distance. Even when CUs are delineated in highly mobile species, the CUs often lack key biological information about what populations have the most conservation need to guide management decisions. Here we implement a framework for rigorous CU identification in the Canada Warbler (Cardellina canadensis), a highly mobile migratory bird species of conservation concern, and then integrate demographic modeling and genomic offset within a CU framework to guide conservation decisions. We find that whole-genome structure in this highly mobile species is primarily driven by putative adaptive variation. Identification of CUs across the breeding range revealed that Canada Warblers fall into two Evolutionarily Significant Units (ESU), and three putative Adaptive Units (AUs) in the South, East and Northwest. Quantification of genomic offset within each AU reveals significant spatial variation in climate vulnerability, with the Northwestern AU being identified as the most vulnerable to future climate change based on genomic offset predictions. Alternatively, quantification of past population trends within each AU revealed the steepest population declines have occurred within the Eastern AU. Overall, we illustrate that genomics-informed CUs provide a strong foundation for identifying current and potential future regional threats that can be used to manage highly mobile species in a rapidly changing world.

Aplasia of the submandibular gland is an uncommon condition and frequently associated with other congenital anomalies. This condition is often asymptomatic although it can lead to hypertrophy of the remaining salivary glands. We present the case of a patient with a left neck mass, found to have submandibular gland aplasia with

In this paper, we study the Cauchy problem for the three-dimensional isentropic compressible Navier-Stokes/Allen-Cahn system, which describes the phase transitions in two-component patterns interacting with a compressible fluid. We establish the existence and space-time pointwise behaviors of global solutions to this non-conserved system. In order to control the source term consisting of the phase variable, we make use of the Green’s function and space-time weighted estimates to prove that the phase variable only contains the diffusion wave whose amplitude decays exponentially in time, so as to show that the density and momentum of the fluid obey the generalized Huygens’ principle.

Cynara scolymus L., called artichoke or globe artichoke, is a perennial herbaceous plant cultivated worldwide. This plant is a common component of the Mediterranean diet and has been used as a remedy for health conditions since antiquity. The aim of this review is to find the health-promoting properties of artichoke, conducting a literature search in PubMed. The results show that 119 studies describe these effects and 17 health benefits of artichoke are reported in the scientific literature. Antioxidant activity and effects on the liver and lipid profile are the main health-promoting properties of this plant. We found that artichoke also improves cardiovascular and gastrointestinal health and exerts anticancer, antimetabolic and antiobesity, prebiotic and probiotic, renoprotective and antidiabetic activities. Only one or two research articles reported the positive effects of this plant on the immune system, arthritis, photoaging, the reproductive system, the nervous system, fungal infections and periodontal diseases. The health benefits are mainly exerted by phenolics. In conclusion, this review shows the health-promoting properties of artichoke. The main beneficial effects are antioxidant activity and effects on lipid profile and the liver, which are mainly mediated by phenolics. The results of the scientific articles described in this review and the molecular mechanisms related to the health benefits of artichoke should be confirmed by future experimental studies.Keywords: Artichoke, Cynara scolymus L., Antioxidant, Hepatoprotective, Lipid profileImpact statement: Artichoke (Cynara scolymus L.) has many health benefits and the main properties are antioxidant activity and effects on the liver and lipid profile.

To describe the impact of population mobility between different cities on the spread of infectious disease, a new infectious disease complex dynamical model is proposed. Moreover, we obtain the basic regeneration number of the model based on applied spectral analysis. And the disease-free equilibrium points and local equilibrium points of the model are discussed, and it is found that two kind equilibrium points are globally asymptotically stable. In addition, the final scale of the presented model is analyzed and an expression for the final scale is obtained. Furthermore, we analyze the impact of population mobility on the spread of infectious diseases via numerical simulations. Our results reveal that the increase of population mobility between two cities leads to more intense disease transmission. Finally, the influence of media effects on the spread of infectious diseases is investigated. It is shown that the spread of diseases is suppressed because of the increase of individual's self-isolation rate. Therefore, controlling the population mobility is an effective initiative to curb outbreaks of infectious diseases throughout the network. These results can provide a theoretical basis for preventing and controlling the spreading of infectious diseases.

The drugs are used at great degree for the medical care, illnesses in animals and food packaging to increase food stability. Still, the reports have showed the likely existence of drug portions in it, assuring one of the major people worries for food assurance. Thus, it is extremely in demand to plan more safe scientific methods to observe drug components in water or food. Therefore, in this work we have synthesized cellulose nanocomposite for Ciprofloxacin (Cip) absorption, detection, or removal and found better results. Besides, antimicrobial activity found excellent results against carbonized material. Composite characterized by Fourier-transform infrared (FTIR), Transmission electron microscope (TEM), Field-emission scanning electron microscopy (FE-SEM) and X-ray photoelectron spectroscopy (XPS).
