The new wave of device-level cyber-attacks has targeted IoT critical applications, such as in power distribution systems integrated with the Internet communications infrastructure. These systems utilise Group Domain of Interpretation (GDOI) as designated by International Electrotechnical Commission (IEC) power utility standards IEC 61850 and IEC 62351. However, GDOI cannot protect against novel threats, such as IoT device-level attacks that can modify device firmware and configuration files to create command and control malicious communication. As a consequence, the attacks can compromise substations with potentially catastrophic consequences. With this in mind, this article proposes a permissioned/private blockchain-based authentication framework that provides a solution to current security threats such as the IoT device-level attacks. Our work improves the GDOI protocol applied in critical IoT applications by achieving decentralized and distributed device authentication. The security of our proposal is demonstrated against against known attacks as well as through formal mechanisms via the joint use of the AVISPA and SPAN tools. The proposed approach adds negligible authentication latency, thus ensuring appropriate scalability as the number of nodes increases.

In the realm of computer vision, image anomaly detection has always been an important research direction. Despite various anomaly detection approaches based on deep neural networks have been developed successively, the progress of end-to-end unsupervised image anomaly detection is still limited. This paper proposes a novel unsupervised anomaly detection automatic adaptive dynamic clustering model named UAD-ADC that can performs end-to-end outlier detection on images without available labels. Specifically, UAD-ADC employs a deep auto-encoder to learn the feature representation of images and combine with data augmentation to improve the quality of learned features. To detect abnormal images, we propose an effective surrogate supervision method and construct a discriminative model based on a deep clustering method. In particular, an iterative optimization method combined with self-paced learning is adopted to select reliability samples to train the discriminant model. Finally, an efficient anomaly scoring strategy is designed to evaluate images to improve anomaly detection performance. Extensive experiments under different outlier ratios on image benchmarks demonstrate that UAD-ADC significantly improves anomaly detection performance compared to the state-of-the-art unsupervised anomaly detection methods.

Background: Statins exert pleiotropic anti-inflammatory and antioxidant effects in addition to their cholesterol-lowering properties. This study aimed to investigate whether statin use is associated with improved outcomes of sepsis. Methods: Data from sepsis patients were extracted from the Medical Information Mart for Intensive Care IV database. Statin users were matched with non-users using propensity-score matching, to balance confounding factors between the groups. Mendelian Randomization (MR) analyses were performed using information from the UK Biobank dataset to explore the potential causal link between low-density lipoprotein cholesterol (LDL-C) levels and LDL-C lowering effects via genetically inhibiting β-hydroxy β-methylglutaryl-coenzyme A reductase and the susceptibility to sepsis, and the sepsis-related 28-day mortality. Main results: The study comprised 31,983 septic patients. 90-day mortality rate was lower among the 10,323 statin users when compared to matched non-users [hazard ratio (HR): 0.612, 95% CI: 0.571 to 0.655]. In-hospital mortality was also lower for statin users compared to non-users (11.3% vs. 17.8%, p<0.0001, HR: 0.590, 95% CI: 0.548 to 0.634). ICU or in-hospital length of stay were similar between statin users and matched non-users. In Cox proportional hazard models and with stratification by medical history of hyperlipidemia or myocardial infarction, we identify almost all sub-populations in which statin therapy was associated with a better outcome. MR analyses further pointed toward pleiotropic effects beyond lipid-lowering effects of statins on sepsis-related outcomes. Conclusions: Statin use is associated with improved outcomes following sepsis-related ICU admission, most likely from its pleiotropic properties, characterized by lower 90-day and in-hospital mortality among statin users.

IntroductionA volvulus occurs when a segment of intestine, usually part of the colon, twists around its mesentery. Following this rotation, initially venous return is disturbed and causes ischemia caused by venous stasis. With the prolongation of obstruction in the mesenteric vessels, along with the distention of the twisted segment of the intestine due to the progressive production of gas by the bacteria inside it, the arterial input is also disturbed, and the mucosal ischemia gradually progresses towards the muscular and serous layers, leading to perforation of the entire thickness of the intestineSigmoid volvulus accounts for 2% to 5% of colonic obstructions in Western countries and 20% to 50% of colonic obstructions in Eastern countries (1). This occurs mostly in patients with lack of mobility and a history of chronic constipation, where the sigmoid colon becomes chronically distended and redundant.Undescended testis (UDT) is defined as one or both testicles absent in scrotal sac when descending processes become disturbed and testis remains inside the peritoneal cavity (2). There are some very known complications of a undescendent intra-abdominal testicle such as cancer, ischemia and infertility(3); But the rotation of the colon around the spermatic cord of one UDT, it is a very rare phenomenon that there is no similar report.In this article, we introduce a 67-year-old man who underwent laparotomy with the diagnosis of sigmoid volvulus, and the intraoperative findings were surprising.

The development of sensitive, fast, and more reliable diagnostic methods to prevent and control the outbreak of life-threatening pandemic infectious diseases, such as COVID-19, according to the WHO recommendations, is always in priority and necessity. Optical diagnostic methods, with their progress in technology, are central to most applications and now, in the health field, are an alternative to conventional methods because of their great sensitivity and capability utilized for SARS-CoV-2 detection such as generally applied PCR technology which is time-consuming, effortful, and has limited availability in resource-limited situations. Herein, we reviewed various optical methods engaged for virus detection such as fluorescence-based techniques, Raman spectroscopy (RS), Plasmonic methods (e.g., SPR, LSPR, SEF, and SERS), ATR-FTIR, super-resolution microscopy (SRM), and some integrated platforms like waveguides and MIP-based biosensors for the development of portable, sensitive, specific, and low-cost POC apparatus for the rapid virus detection.

Metformin hydrochloride, an antihyperglycemic agent, and sulindac, a nonsteroidal anti-inflammatory drug, are FDA-approved drugs known to exert anticancer effects. Previous studies demonstrated sulindac and metformin’s anticancer properties through mitochondrial dysfunction and inhibition of mitochondrial electron transport chain (ETC) complex I, as well as key signaling pathways. In this study, various drugs were adminsitered to A549 lung cancer cells, and results revealed that a combination of sulindac and metformin enhanced cell death compared to administration of the drugs separately. To measure superoxide production over time, we employed a time-lapse fluorescence imaging technique using mitochondrial-targeted hydroethidine. Fluorescence microscopy data showed largest increases in superoxide production in the combination treatment of metformin and sulindac. Results showed significant differences between the combined drug treatment and control groups, as well as between the positive control and control groups. This approach can be utilized to quantify anticancer efficacy of drugs, creating possibilities for additional therapeutic options.

A Chronic Non-Healing Ulcer on the Lower Lip Mimicking Malignancy –

In order to solve the path planning problem of mobile robots, a novel hybrid strategy improved wild horse optimizer (HI-WHO) is proposed in this paper. The algorithm utilizes Sobol sequence to initialize the population, which ensures a uniform distribution of initial solutions in the search space. It also integrates Lévy flight strategy and nonlinear dynamic adaptive factor to balance the exploration and exploitation ability and improve the search efficiency and quality at different stages of the algorithm. In addition, the algorithm can ensure the global search capability and the ability to jump out of the local optimum by using the lens imaging opposition-learning strategy and greedy mechanism. In the simulation experiments, 20 benchmark functions are selected to verify the effectiveness of the proposed method. Finally, the improved algorithm, combined with cubic B-Spline interpolation, solves the path planning problem by establishing the mathematical model for mobile robot path planning, and the performance is evaluated by conducting simulation experiments in a simple experimental environment and a real environment with grid map. The results show that the HI-WHO has good stability and optimal comprehensive performance, showcasing its effectiveness in addressing the robot path planning problem.

Large-scale spatial patterns of species richness are one of the central issues in ecology. Although hypotheses based on effects of contemporary climate, evolutionary history and historical climate change have been employed to explain the mechanisms underlying species richness patterns, variation in relative contribution of different hypothesis remains a major challenge. Here, using newly-compiled distribution data with a spatial resolution of 100 * 100 km2 for 43,023 seed plant species in eastern Eurasia, we mapped species richness patterns for plants with different growth forms (i.e., woody vs. herbaceous) and range sizes (i.e., wide-ranged vs. narrow-ranged species), and compared the contribution of four hypotheses on these patterns, i.e., freezing tolerance hypothesis, historical climate change hypothesis, Janzen hypothesis and diversification rate hypothesis. We found that species richness of all seed plants presented a clear latitudinal gradient and was the highest in southwestern China and Central Asian mountains. Notably, species richness patterns and their dominant hypotheses differed between species groups. Historical climate change dominated richness patterns of overall, herbaceous and wide-ranged herbaceous species. The freezing tolerance hypothesis dominated those for all woody and wide-ranged woody species, while the Janzen hypothesis dominated narrow-ranged woody and herbaceous species. Our study suggests that different hypotheses contribute to large-scale species richness patterns via their dominant effects in different species groups. Interestingly, our study did not support the diversification rate hypothesis, but demonstrated high contribution of historical climate change to plant diversity, providing new perspectives on the mechanisms of plant diversity patterns in eastern Eurasia.

This paper provides an overview of passive cooling technologies used in photovoltaic (PV) and photovoltaic-thermal (PVT) modules that serve as an alternative energy source for countries with high solar irradiation and cooling requirements. Passive cooling is an attractive solution for PV panel applications because, unlike active cooling methods, it does not require external energy for the cooling process. The main objective of this paper is to provide a comprehensive overview of passive cooling technologies and their applications in PV and PVT modules while highlighting the challenges and potential areas for future research in this field. Various cooling techniques are discussed, including radiative, air, liquid, and phase change materials (PCM) based methods, with particular emphasis on their efficiency and effectiveness in different scenarios. Previous studies addressing advances in improving the electrical and thermal efficiency of PV and PVT modules are also reviewed. This paper covers a wide range of cooling techniques, including full-spectrum, airflow, fin, heat pipe, and nanofluids, as well as PV-PCM and PVT-PCM. Overall, the paper highlights the potential of passive cooling techniques for the effective and efficient use of solar energy in PV and PVT systems. It also highlights the challenges and future research prospects associated with these technologies. In summary, this study provides valuable insight into the potential of passive cooling technologies as a means to improve the performance and efficiency of solar energy systems, proving useful to researchers and engineers in the renewable energy and sustainable development fields, particularly those focused on developing cooling systems for PV and PVT applications.

Understanding microbial migration and survival mechanisms in dust events can elucidate genetic and metabolic exchange between environments and help predict the atmospheric pathways of ecological and health-related microbial stressors. Dust-borne microbial communities have been previously characterized, but the impact of active bacteria within transported communities remains limited. Here, we analyzed samples collected during dust events in Israel, using amplicon sequencing of the 16S rRNA genes and transcripts. Different air trajectories and wind speeds were associated not only with microbial community composition variations but also with those of active bacteria. Active dust-borne bacteria exhibited positive interactions, including highly active carbon and nitrogen cycling bacteria, potential degraders of heavy metals and organic compounds, biofilm-forming, and pathogenic bacteria. This study provides insights into the potential interactive relationships and survival of active microorganisms within the extreme dust environment.

1.Biodiversity loss is occurring at an unprecedented rate, but its consequences on ecosystem robustness remain difficult to predict. Both theoretical and empirical work have suggested that species extinctions for taxa with different dietary niche in food webs (e.g., species generality) can produce unequal consequences. However, the diverse definitions of species generality impede us to obtain a comprehensive understanding of the impact of specialist/generalist (i.e., species with low/high generality) loss on ecosystem robustness. 2.Here, we consider five generality metrics (one binary generality, one effective link generality, and three weighted generality, respectively, by link strength, biomass and energy flux) at both species- and network-level. We use a multi-trophic food web model in combination with empirical data to explore the relationship between generality and species richness. We further perform secondary extinctions by sequentially removing species with either maximal or minimal generality under two generality ranking scenarios to examine food web robustness to species loss, where species generality is ranked based either on their realized or potential dietary niche. 3.Results show that at a network-level, all considered generality metrics increase with species richness, albeit at markedly different rates. Yet the relative richness of generalists to specialists stays roughly invariant, indicating that generalist-prone communities as a consequence of specialist loss might probably just a transitory state and may eventually return to a more specialized species assemblage. The increased network-level generality is due to the enhanced heterogeneity in species-level generality rather than the increased generalist richness. 4.Our sequential species elimination experiment demonstrates substantial variability in ecosystem robustness responses to different generality metrics. In both generality ranking scenarios, removing generalists (specialists) measured by biomass-weighted generality is the most (least) detrimental to food web robustness, suggesting that species with dominant biomass should be of high biodiversity concern. Further, robustness loss in response to generalist removal is larger in the realized niche ranking scenario than in the potential niche ranking scenario, implying that realized rather than potential dietary niche is more effective to identify species priority in conservation. 5.Our work demonstrates a consistent relationship between network-level generality and species richness, but the variability in metrics also indicates that different ecological processes are at play behind each generality metric. We recommend that studies investigating biodiversity conservation under various anthropogenic forcing should include biomass-weighted metrics, and pay more attention to species’ dietary niche realized in the current food webs instead of the dietary niche recorded in the historic food webs.

The Grivet monkey (Chlorocebus aethiop aethiops) is an old-world primate Monkey species distributed on the east of the White Nile in Sudan to Ethiopia, Eritrea, and Djibouti. The study on activity patterns and feeding habits of Grivet Monkeys in and around Wondo Genet College of Forestry and Natural Resource was carried out from February 2021 to August 2022 during both the wet and dry season. Instantaneous scan sampling method was used at 15-min intervals for up to 10 minutes duration. During each scan, individuals were recorded as performing one of the following activities: feeding, moving, resting, grooming, playing, and others. Descriptive statistics and inferential statistics such as One-way ANOVA, Kruskal Wallis test, and Mann-Whitney U-test were used to analyze data.On average, the greatest proportion of the activity time budget of the grivet monkey was devoted to feeding (29.5±0.6%), followed by resting (27±0.8%), moving (26±0.2%), grooming (9±0.2%), playing (5.5±0.6%) and the least time spent on other social activities (3±0.2%). They feed 42 food sources grouped into 41 plant species and one insect. On average, the forb of leaf 32±3.2% comprised the highest percent proportion of their diet, whereas, roots (0.3±0.2%) and insects (0.5±0.4%) comprised the least. Psidium guava was the top preferred plant species and Callistemon linearis was the least preferred plant species by the grivet monkey. Due to the existence of low quality of food in human dominated area, Grivet monkey most of their time spent on feeding activity. Therefore, concerned body and regional governments need to take action to stop deforestation of the natural forests and sustainable management must be needed for the top preferred plant species.

Spinal epidural lipomatosis due to the corticosteroids; a case reportAbdollah Hadi1, Omid Masomi21. Associated professor, Department of Orthopaedics, Isfahan university of medical science, Isfahan, Iran.2. Department of Orthopaedics, Isfahan university of medical science, Isfahan, Iran.Abstract:Spinal epidural lipomatosis (SEL), an abnormal localized or tumor-like accumulation of fat in the epidural space, is an infrequent complication of chronic steroid usage and an uncommon cause of spinal cord compression. A patient with a history of rheumatologic condition on chronic corticosteroids presented with a clinical picture of thecal sac compression and was diagnosed with SEL.Background:Spinal epidural lipomatosis (SEL) is a condition in which adipose tissue accumulates excessively inside the spinal canal, causing the neural elemnt to become compressed. The incidence of symptomatic SEL is extremely rare and often associated with the use of exogenous steroids. SEL has also been associated with obesity and Cushing syndrome/disease (hypercortisolism), although they are less common. On rare occasions, epidural lipomatosis causes nerve root compression or spinal cord compression, leading to symptoms. There is a high rate of misdiagnosis of SEL because it can mimic the symptoms of spinal stenosis or degenerative joint disease. (1). The symptoms of spinal cord compression are primarily determined by the level of compression in the spinal cord. Men are more likely to experience SEL than women, with a ratio of 3:1, and the average age at presentation is 43. (2). The diagnosis of SEL can be best established with magnetic resonance imaging (MRI). The diagnostic criterion for SEL is an epidural adipose tissue thickness exceeding 7 mm (3, 4). We represent a case of spinal epidural lipomatosis due to the treatment with corticosteroids.Case:A 48-year-old man was admitted to Al-Zahra University Hospital in Isfahan, Iran with complaints of progressive weakness and numbness of the right lower limb. The weakness progressed gradually from one year before admission in an ascending fashion to involve the lower limbs. His symptoms had worsened rapidly over a period of two weeks preceding his admission to our hospital, to the extent that he had difficulty moving his right lower limb. His past medical history was a rheumatologic condition, with the history of five mg of prednisolone daily in the last eight years. Physical examination on admission revealed a well-nourished male patient who weighed 95 kg and measured 180 cm tall (body mass index, 29.3). Neurological examination of his cognitive function and cranial nerves were within normal ranges. Motor examination of the lower limbs revealed a significant weakness. Sensory examination showed hypoesthesia and impaired proprioception in right lower limb, with decreased sensation. The motor and sensory examination of the upper limbs was normal. On investigation, routine laboratory blood tests including complete blood count, liver function, and renal function analysis were within normal ranges. An MRI study of the lumbar and sacral spine was done and the radiologist reported fatty degeneration of paraspinal muscles and spinal lipomatosis in L4-L5 and L5-S1. They also reported extradural lipomatosis with compression effect on thecal sac in the same area (Figure 1&2).The patient underwent posterior laminectomy from L4 to S1 vertebral levels. A dorsally located and relatively vascular firm epidural fatty tissue was encountered, which was not infiltrating the bone or the dura; it was dissected hardly and incompletely removed due to its stickiness. Histological examination of the operative specimen demonstrated vascularized mature fibro-fatty tissue consistent with the diagnosis of lipomatosis. The patient had an uneventful postoperative period. The patient was able to walk with assistance two days after surgery and within a week, he was experiencing gradual improvement in his paraparesis and his motor function. He was discharged on the 7th postoperative day. He continued to show progressive neurological improvement with extensive outpatient physiotherapy program and finally was able to walk independently after 10 days. At 3-month follow-up, his examination revealed a complete neurological function.

Root fracture has been defined as a fracture involving dentin, cementum, pulp and periodontal ligament. A multidisciplinary approach is adopted to treat dental trauma in clinical practice. This case report described the use of 18-months VITAPEX paste dressings to induce the formation of hard tissue barriers in the multidisciplinary management of

During the post-stroke recovery process, the brain undergoes reorganization, compensating for the loss of ipsilesional corticospinal and corticobulbar pathways, resulting in increased contralesional activity during paretic arm movement tasks. A better understanding of the mechanisms behind this may enhance motor recovery assessments, providing insight into the extent of post-stroke contralesional motor cortical adaptation. This proof-of-concept study involves eight healthy controls and ten post-stroke participants. Electroencephalographic (EEG) and deltoid electromyographic (EMG) data was collected from each participant during the performance of an upper-limb shoulder abduction task. Phase coupling between beta-band motor cortex EEG and deltoid muscle EMG was assessed using Multi-Phase Locking Value (M-PLV). Using the calculated EEG-EMG phase coherence, nerve conduction delay from the contralateral motor cortex to the deltoid muscle of the paretic arm was estimated for all participants. Our results show several differences between post-stroke and control participants; ipsilateral (stroke-contralesional) motor cortex beta-band phase coherence behavior is altered in post-stroke participants, showing a significant difference in ipsilateral EEG-EMG coherence values, ipsilateral time course percentage above the significance threshold, and ipsilateral time course area above the significance threshold. M-PLV analysis provides evidence for post-stroke contralesional motor cortex adaptation, highlighting its increased role in the paretic shoulder abduction task. Nerve conduction delay between the motor cortexes and deltoid muscle is significantly higher in stroke participants. Beta-band M-PLV phase coherence analysis shows greater phase-coherence distribution convergence between ipsilateral and contralateral motor cortices in stroke participants, potentially indicative of maladaptive neural adaptation resulting from a greater reliance on the contralesional motor cortex.

Introduction We describe a rare case of an adolescent girl with paroxysmal atrial fibrillation originating from the right atrial appendage diverticulum and successfully converted to sinus rhythm after surgical intervention. Methods A 19-year-old girl was referred to the hospital for a catheter ablation of paroxysmal atrial fibrillation. Conventional ablation strategies are ineffective. Activation mapping showed the root of the free wall atrial appendage was first excited and catheter modeling (3D Carto map) shows a sac-like structure. Results We did selective angiography and further Computed tomography angiography (CTA) and Transesophageal ultrasonography (TTE) which showed diverticulum originating from the right atrial appendage. Hence the patient was referred to cardiac surgery and had no recurrent atrial fibrillation at three months postoperative follow up. Conclusions Right atrial appendage diverticula is an extremely rare malformation that can coexist with atrial tachyarrhythmia. Surgical ligation or excision of the abnormal structure with local ablation can achieve excellent results.

Introduction Glanzmann first identified Glanzmann’s thrombasthenia (GT) in 1918. Platelets with GT, a severe congenital platelet condition, lack glycoprotein IIb/IIIa (integrin aIIbb3), which results in a significant defect in platelet aggregation [1]. Although uncommon, when present it is more prevalent in families with consanguineous marriages. Regarding the incidence of GT, there was no appreciable difference between the patients who were male and female. Visceral haemorrhage is a rare clinical symptom of GT; mucocutaneous haemorrhage is the most common clinical symptom [2]. A general wellness checkup may not always detect anomalies linked to the GT; as a result, the GT is frequently ignored or incorrectly diagnosed. For an evaluation of GT, laboratory tests are necessary. In individuals with this disease, platelet structure and count are usually within normal limits, but the bleeding time is much greater [3]. Consequently, the confirmation of GT is based on the recognition of abnormalities in platelet aggregation, and it is crucial to use more precise techniques, such as flow cytometry or gene detection, to make a definitive diagnosis [4]. There is currently no known full treatment for GT; instead, symptomatic care is the focus [5]. Here, we present a difficult case of GT and examine its clinical characteristics, diagnostic criteria, therapeutic options, and prognosis.

Background: This study aims to improve practices in pediatric radiation oncology in LMIC by sharing an institutional experience of radiation therapy (RT) for pediatric cancer at the Aga Khan University Hospital. Methods: All patients from January 2009 to December 2020 who received radiation therapy at Aga Khan University Hospital were included. Records were retrospectively reviewed from hospital information management system (HIMS) and radiation oncology information system were searched to identify children aged up to 19 years of age who received RT based on the pediatric protocol. Data was reviewed for frequencies and percentages were calculated for demographics, clinical characteristics, and treatment-related variables. Results: A total of 496 patients were offered RT for soft tissue and extra osseous sarcomas (n=115 patients, 23.2%), lymphomas and reticuloendothelial neoplasms (n=88 patients, 17.7%) and CNS and miscellaneous intracranial and intraspinal neoplasms (n=86 patients, 17.3%) and malignant bone tumors (n=77, 15.5% patients). The most common regions for radiation were head and neck (n=144, 29%) and CNS (n= 123, 24.3%). General anesthesia was used for radiation planning and/or execution of treatment in 122 (26.8%) patients. More than half the patients (n=261, 53.16%) received RT in the postoperative setting, 89 (18.13%) had RT as consolidative treatment. 30 (6.1%) leukemia patients received prophylactic radiation therapy and 103 (20.98%) received RT as a definitive treatment modality. Conclusions: Our study reinforces the use of radiation therapy in multidisciplinary management of different pediatric tumors. A multi-level pediatric cancer registry is required to assess the utilization of radiotherapy for different pediatric tumors. This will help in planning systems to cater to the needs of pediatric oncology management and survivorship.

Background As both tumor and germline sequencing become more common practice in children with cancer, it will be necessary to anticipate and address potential ethical issues. This study aimed to elicit the perspectives of adolescents with cancer, and parents of children with cancer, regarding tumor and germline genomic sequencing in pediatric oncology. Procedure Semi-structured interviews were conducted with adolescents/young adults with cancer, and parents/guardians of children with cancer. The interview guide included questions on potential benefits of genomic sequencing, heritable cancer predisposition conditions, impacts on family relationships, and secondary findings. Demographic information was also collected, and baseline genetics knowledge was assessed. Results Participants reported several ways they believed sequencing results could be valuable, including more targeted cancer therapy and knowledge regarding heritable variants. However, opinions varied on what information would be useful, with many participants reporting an interest only in those results which would directly impact cancer therapy. Multiple people expressed concerns about results that could be undesirable or even harmful, such as secondary findings unrelated to cancer. Several parents reported feeling guilty about their children having cancer, whether or not a genetic predisposition to cancer was found. Conclusions Patients and parents held a wide variety of opinions on the utility and proper implementation of genomic sequencing for cancer. Most participants saw potential benefits to such testing, but many participants felt they lacked the knowledge to make an adequately informed decision on results derived from complex scientific techniques, and reported. These findings will help inform the process of obtaining informed consent for genomic sequencing in children with cancer.
