Ground-based and additional science support for SMILE

The joint European Space Agency and Chinese Academy of Sciences Solar wind Magnetosphere Ionosphere Link Explorer(SMILE)mission will explore global dynamics of the magnetosphere under varying solar wind and interplanetary magnetic field conditions,and simultaneously monitor the auroral response of the Northern Hemisphere ionosphere.Combining these large-scale responses with medium and fine-scale measurements at a variety of cadences by additional ground-based and space-based instruments will enable a much greater scientific impact beyond the original goals of the SMILE mission.Here,we describe current community efforts to prepare for SMILE,and the benefits and context various experiments that have explicitly expressed support for SMILE can offer.A dedicated group of international scientists representing many different experiment types and geographical locations,the Ground-based and Additional Science Working Group,is facilitating these efforts.Preparations include constructing an online SMILE Data Fusion Facility,the discussion of particular or special modes for experiments such as coherent and incoherent scatter radar,and the consideration of particular observing strategies and spacecraft conjunctions.We anticipate growing interest and community engagement with the SMILE mission,and we welcome novel ideas and insights from the solar-terrestrial community.

Pseudomembranous conjunctivitis in a patient with DRESS syndrome

Dear Editor,Drug rash with eosinophilia and systemic symptoms(DRESS)syndrome is a drug reaction featuring high fever,eosinophilia,skin rashes,and multi-organ involvement that may be fatal.Ocular manifestations,including cicatrizing conjunctivitis,corneal infiltration,and anterior uveitis,are rarely reported[1-6]but may cause serious complications if untreated.Therefore,it is important to diagnose DRESS syndrome in patients with ocular features promptly with appropriate treatment.This article reports a case diagnosed with DRESS syndrome associated with pseudomembranous conjunctivitis secondary to carfilzomib.

Guidelines for the application of artificial intelligence in the diagnosis of anterior segment diseases(2023)

The landscape of ophthalmology has obser ved monumental shifts with the advent of artificial intelligence(AI)technologies.This article is devoted to elaborating on the nuanced application of AI in the diagnostic realm of anterior segment eye diseases,an area ripe with potential yet complex in its imaging characteristics.Historically,AI’s entrenchment in ophthalmology was predominantly rooted in the posterior segment.However,the evolution of machine learning paradigms,particularly with the advent of deep learning methodologies,has reframed the focus.When combined with the exponential surge in available electronic image data pertaining to the anterior segment,AI’s role in diagnosing corneal,conjunctival,lens,and eyelid pathologies has been solidified and has emerged from the realm of theoretical to practical.In light of this transformative potential,collaborations between the Ophthalmic Imaging and Intelligent Medicine Subcommittee of the China Medical Education Association and the Ophthalmology Committee of the International Translational Medicine Association have been instrumental.These eminent bodies mobilized a consortium of experts to dissect and assimilate advancements from both national and international quarters.Their mandate was not limited to AI’s application in anterior segment pathologies like the cornea,conjunctiva,lens,and eyelids,but also ventured into deciphering the existing impediments and envisioning future trajectories.After iterative deliberations,the consensus synthesized herein serves as a touchstone,assisting ophthalmologists in optimally integrating AI into their diagnostic decisions and bolstering clinical research.Through this guideline,we aspire to offer a comprehensive framework,ensuring that clinical decisions are not merely informed but transformed by AI.By building upon existing literature yet maintaining the highest standards of originality,this document stands as a testament to both innovation and academic integrity,in line with the ethos of renowned journals such as Ophthalmology.

Identification of Groundwater Potential Zones in Samendeni Watershed in Sedimentary and Semi-Arid Contexts of Burkina Faso, Using Analytic Hierarchy Process (AHP) Method and GIS

Demand for water increases in Samendeni regarding the undertaken agricultural projects while pressure on surface water from global warming/evapotranspiration also increases. Thus, the need to evaluate the groundwater potential in the catchment is crucial as alternative supplier of water and resilience to climate hazards. The AHP was performed integrating ten influencing factors such as geomorphology, geology, soil, land use/land cover (lulc), slope, rainfall, drainage density, borehole rate & depth and piezometric level to generate groundwater potential zones (GWPZs) in Samendeni watershed (4420 km2). All the factors were processed and ranged into five (5) classes. Weight was assigned to each class of thematic layer. These thematic layers were then reclassified based on the normalized weight to be used in the calculation of groundwater potential zones (GWPZ). The final output, groundwater potential map, revealed a significant groundwater potential with very good (11%), good (31%), moderate (30%), poor (20%), and very poor (8%) of proportion. The interesting (very good, good) GWPZs in the study area are mostly in the central towards the east. The poor zones in term of groundwater potential are concentrated in the upper west region of the watershed. Besides the cross-validation with the relationship between different groundwater potential zones and the wells available in the study area, the overall accuracy was estimated to 88% provided from the result of the similarity analysis where 22 out of the 25 validation wells match with the expected yield classes of GWPZs. The statistics from that validation revealed the performance of AHP method to delineate groundwater potential zones at catchment level.

A Case of Serratia marcescens Conjunctivitis in a Young Male after Exposure to Contaminated Shampoo in a Fitness Club

The contamination of shampoo with bacteria is not very common but can happen and can be a potential cause of conjunctivitis. This case report describes a 24-year-old male who developed conjunctivitis after using a Serratia marcescens contaminated shampoo in a fitness club. The patient had redness, swelling, and discharge in both eyes. Cultures of the shampoo and eye swabs were positive for S. marcescens with indistinguishable DNA fingerprints. The patient was treated with an eye drop antibiotic and his symptoms resolved within a week. This case highlights the possibility of exposure in places where shampoos containers are refilled or shared. The avoidance of refilling them and using replaceable cartridges, single-sealed refill bags, or bringing personal shampoo is highly recommended to prevent such incidents.

Hopf Algebra of Labeled Simple Graphs

A lot of combinatorial objects have a natural bialgebra structure. In this paper, we prove that the vector space spanned by labeled simple graphs is a bialgebra with the conjunction product and the unshuffle coproduct. In fact, it is a Hopf algebra since it is graded connected. The main conclusions are that the vector space spanned by labeled simple graphs arising from the unshuffle coproduct is a Hopf algebra and that there is a Hopf homomorphism from permutations to label simple graphs.

A Novel Approach for Optimum Conjunctive Use Management of Groundwater and Surface Water Resources under Uncertainty

Uncertainty in determining optimum conjunctive water use lies not only on variability of hydrological cycle and climate but also on lack of adequate data and perfect knowledge about groundwater-surface water system interactions, errors in historic data and inherent variability of system parameters both in space and time. Simulation-optimization models are used for conjunctive water use management under uncertain conditions. However, direct application of such approach whereby all realizations are considered at every-iteration of the optimization process leads to a highly computational time-consuming optimization problem as the number of realizations increases. Hence, this study proposes a novel approach—a Retrospective Optimization Approximation (ROA) approach. In this approach, a simulation model was used to determine aquifer system responses (draw-downs) which were assembled as response matrices and incorporated in the optimization model (procedure) as coefficients in the constraints. The sample optimization sub-problems generated, were solved and analyzed through ROA-Active-Set procedure implemented under MATLAB code. The ROA-Active Set procedure solves and evaluates a sequence of sample path optimization sub-problems in an increasing number of realizations. The methodology was applied to a real-world conjunctive water use management problem found in Great Letaba River basin, South Africa. In the River basin, surface water source contributes 87% of the existing un-optimized total conjunctive water use withdrawal rate (6512.04 m3/day) and the remaining 13% is contributed by groundwater source. Through ROA approach, results indicate that the optimum percentages contribution of the surface and subsurface sources to the total water demand are 58% and 42% respectively. This implies that the existing percentage contribution can be increased or reduced by ±29% that is groundwater source can be increased by 29% while the surface water source contribution can be reduced by 29%. This reveals that the existing conjunctive water use practice is unsustainable wherein surface water system is overstressed while groundwater system is under-utilized. Through k-means sampling technique ROA-Active Set procedure was able to attain a converged maximum expected total optimum conjunctive water use withdrawal rate of 4.35 × 104 m3/day within a relatively few numbers of iterations (6 to 8 iterations) in about 2.30 Hrs. In conclusion, results demonstrated that ROA approach is capable of managing real-world regional aquifers sustainable conjunctive water use practice under hydro-geological uncertainty conditions.

Kepler’s Conjunction for Two Strong Earthquakes in Türkiye in February 2023

This work is devoted to the study of the relationship between strong earthquakes and planetary configurations using the example of two consecutive strong earthquakes that occurred in Türkiye (Turkey), on February 6, 2023. It is shown that at the time of the earthquakes, linear alignment of the planets along the Jupiter-Venus-Sun line was observed, that is, the astronomical trigger belonged to the generalized Kepler conjunction scheme (gKc), when the Earth does not participate in the linearization scheme. It is shown that for the first earthquake that occurred at 01:17 UTC, the ratio of the distances between Jupiter-Earth and Jupiter-Mars was close to an integer value equal to 5.993. For the second earthquake that occurred on the same day at 10:25 UTC, no integer resonance ratios were detected, however, it was found that the terrestrial e UTC line at the time of the earthquake passed through the position of Mercury. Recall that the 12-hour line of the eUTC chart is always oriented towards the Sun. The conclusions of the work once again confirm the correctness of the theories of Archimedes and Kepler and convince us of the existence of a gravitational phenomenon that does not depend on the distances and masses of planets, has a pronounced inertial and wave character and does not fit into the general theory of relativity, developed in the last century by Albert Einstein.

The Effect of BCG-PSN on T-cell Subsets and Cytokines in Vernal Conjunctivitis

The effects of BCG PSN on T cell subsets and cytokines in vernal conjunctivitis were observed. The level of total IgE was quantitatively determined before and after treatment with BCG PSN by allergen diagnostic instrument in vitro . The content of T cell subsets of peripheral blood and cytokine were determined by using indirect immune fluorescence method, and IL 4 and INF γ were quantified by ELISA. The results showed that the level of total IgE was substantially reduced ( P <0.01) after treatment in the BCG PSN group. Meanwhile, CD + 8 was decreased, CD + 4 and CD + 4/CD + 8 ratio elevated with significant differences ( P <0.05) as compared with pre treatment results. The changes in total IgE, CD + 8 ,CD + 4 and CD + 4/CD + 8 ratio after treatment also presented significant differences ( P <0.05) between BCG PSN group and routine treatment group. The level of IL 4 in serum declined ( P <0.05) after treatment in the BCG PSN group, and INF γ went up ( P <0 05). IL 4 and INF γ in serum showed significant differences ( P <0.05) between two groups after treatment. It is concluded that BCG PSN has a bi directional immunoregulating effect. It can bring CD + 4 and CD + 8 into homeostasis, thereby preventing the occurrence of anaphylaxis. At the same time, BCG PSN can restrain Th 2, decrease the synthesis of IL 4, switch the balance of Th l/Th 2 to Th 1 side, boost up the predominance of Th 1 relatively, which is propitious to perennial stabilization and recovery of vernal conjunctivitis.

Semaphorin 3A controls allergic and inflammatory responses in experimental allergic conjunctivitis

AIM: To assess the efficacy of topical Semaphorin 3A(SEMA3A) in the treatment of allergic conjunctivitis.METHODS: Experimental allergic conjunctivitis(EAC)mice model induced by short ragweed pollen(SRW) in 4-week-old of BALB/c mice, mice were evaluated using haematoxylin and eosin(H&E) staining, immunofluor-escence and light microscope photographs. Early phase took the samples in 24 h after instillation and late phase took the samples between 4 to 14 d after the start of treatment. The study use of topical SEMA3A(10 U, 100 U,1000 U) eye drops and subconjunctival injection of SEMA3 A with same concentration. For comparison, five types of allergy eyedrops were quantified using clinical characteristics.· RESULTS: Clinical score of composite ocular symptoms of the mice treated with SEMA3 A were significantly decreased both in the immediate phase and the late phase compared to those treated with commercial ophthalmic formulations and non-treatment mice. SEMA3 A treatment attenuates infiltration of eosinophils entering into conjunctiva in EAC mice. The score of eosinophil infiltration in the conjunctiva of SEMA3 A 1000 U-treated group were significantly lower than low-concentration of SEMA3 A treated groups and non-treated group. SEMA3 A treatment also suppressed T-cell proliferation in vitro and decreased serum total Ig E levels in EAC mice. Moreover, treatment of SEMA3 A suppressed Th2-related cytokines(IL-5, IL-13 and IL-4)and pro-inflammatory cytokines(IFN-γ, IL-17 and TNF-α)release, but increased regulatory cytokine IL-10 concentration in the conjunctiva of EAC mice.CONCLUSION: SEMA3 A as a biological agent, showed the beneficial activity in ocular allergic processes with the less damage to the intraocular tissue. It is expected that SEMA3 A may be contributed in patients with a more severe spectrum of refractory ocular allergic diseases including allergic conjunctivitis in the near future.

Effects of vernal and allergic conjunctivitis on severity of keratoconus

AIM: To demonstrate the effects of two different types of allergic conjunctivitis on severity of keratoconus (KC). ·METHODS: We retrospectively reviewed the medical records of 171 KC patients referred between June 2010 and June 2011. The KC patients were divided into 3 groups as KC (group A), KC with vernal keratoconjunctivitis (VKC) (group B) and KC with allergic conjunctivitis (AC) (group C). Main outcome measures were demographic and ocular clinical features including age at presentation, gender, spherical equivalent (SE), best spectacle corrected visual acuity (BCVA), mean keratometric measurement (Km), central corneal thickness (CCT), and intraocular pressure (IOP). Groups were compared in term of study variables. · RESULTS: The median age at presentation was significantly lower in group B (P 【0.001). According to the median SE (P =0.003), BCVA(P =0.022), Km(P 【0.001), CCT (P =0.015) and Amsler-Krumeich classification (P 【 0.001), KC was more severe in group B. There was no significant difference in terms of IOP and corrected IOP among the groups (P =0.44), however there were 4 patients who had increased corrected IOP developed after topical corticosteroid use in group B. The differences among the groups persisted even after controlling for age and gender. · CONCLUSION: Our findings demonstrated a more severe KC in VKC patients despite their younger age which suggests evaluation of VKC patients as a separate group in keratoconus disease.

Effect of diluted povidone iodine in adenoviral keratoconjunctivitis on the rate of subepithelial corneal infiltrates

AIM: To evaluate the clinical characteristics of adenoviral keratoconjunctivitis, the management modalities, as well as the incidence of subepithelial corneal infiltrates(SEI).METHODS: Patients with characteristic clinical symptoms and signs, who presented to our clinic within the first week of symptoms and received the diagnosis of adenoviral keratoconjunctivitis between January 2013 and April 2016, were included in the study. A total of 211 patients were included in the study. Patients were evaluated for the incidence of clinical signs, late complications, management preferences, and the effect of diluted povidone-iodine(d-PVP-I) 2%. RESULTS: Patients’ mean age was 33.03±14.76 y. We observed an increase in the number of cases according to the years. At presentation and/or early follow-up, the clinical signs were conjunctival hyperemia(100%), conjunctival follicules(79.1%), edema of the eyelids(39.3%), chemosis(16.1%), pseudomembrane formation(16.6%), and corneal epitheliopathy(29.9%). During late follow-up 13.3% patients developed conjunctival subepithelial fibrosis, and 39.8% developed SEI. A significant decrease in the incidence of SEI development was observed in patients who used d-PVP-I 2%(P=0.032;33.3% vs 45.9%, respectively in patients who received d-PVP-I 2% and who did not).CONCLUSION: Adenoviral keratoconjunctivitis has a tremendous effect on patient’s comfort and abilities in short-term. Additionally, almost half of the patients develop visual problems related to SEI. According to our clinical experience, using d-PVP-I 2% in the first days of adenoviral keratoconjunctivitis might be helpful in reducing the risk of SEI as a complication.

Ragweed pollen induces allergic conjunctivitis immune tolerance in mice via regulation of the NF-κB signal pathway

AIM:To investigate the feasibility and mechanism of immune tolerance in allergic conjunctivitis.METHODS:The allergic conjunctivitis immune tolerance mice model was established by ragweed pollen(RW)and the related cytokines were detected.The mice were divided into 9 groups and the maslinic acid(MA)or PBS were given for different group after modeling.The expression levels of chemokine ligand 5(CCL5)and P-65 in the conjunctival tissue were analyzed by immunohistochemistry,quantitative reverse transcription polymerase chain reaction(q RT-PCR)and Western blot.The percentage of interleukin-17(IL-17)and CD4+CD25+in the splenocyte supernatant was analyzed by flow cytometry.Fur thermore,the serum and splenocyte supernatant concentration of total-IgE,interleukin-10(IL-10),and IL-17 was analyzed by enzyme linked immune response(ELISA).RESULTS:After the model was established,symptoms of conjunctivitis were alleviated,the level of P-65,CCL5,IL-17,and total-IgE was raised,while the expression of IL-10,CD4+CD25+was decreased.This result fully demonstrated that a typical IL-17/regulatory-T-cells(Treg cells)imbalance and NF-κB activation.When the NF-κB signal pathway was suppressed,it showed that there was a further relief of conjunctivitis in mice.At the same time,the expression of total-IgE,IL-17,and CCL5 was decreased and the expression of anti-inflammatory factor(IL-10,CD4+CD25+)was increased.CONCLUSION:In the state of immune tolerance,symptoms of conjunctivitis in mice are alleviated,the Th-17 cells of allergic conjunctivitis mice are inhibited,and Treg cells activity is enhanced.
