The Discovery of a Citrus Yellow Vein Clearing Virus Hacienda Heights Isolate Diversifies the Geological Origins of the Virus in California, United States

The citrus yellow vein clearing virus (CYVCV) is an emerging threat to the U.S. citrus industry. Reports from China shows it cause significant reductions in fruit yield and growth, particularly in lemon trees. In 2022, CYVCV was detected in a wide range of citrus cultivars in localized urban properties in Tulare, California. In 2024, a CYVCV-infected lemon tree was detected in Hacienda Heights in Los Angeles County, California, geographically separated from the Tulare foci. Through long-read sequencing technology, the whole-genome sequence of a CYVCV isolate from Hacienda Heights (designated as CYVCV-CA-HH1, Accession number PP840891.1) was obtained. Sequence alignments and neighbornet analysis strongly suggested that the CYVCV-CA-HH1 isolate has a different origin than the Tulare CYVCV (CYVCV CA-TL) isolates. The CYVCV CA-TL isolates were grouped with those from South Asia (India and Pakistan) and the Middle East (Türkiye), while the CYVCV-CA-HH1 isolate was grouped with isolates from East Asia (China and South Korea). Maximum likelihood phylogenetic analysis further supports this finding, showing that the CYVCV-CA-HH1 isolate shares the most recent common ancestor with a South Korean lineage, which derives from Chinese isolates. Together, our data suggest a diverse geological origin of CYVCV isolates in California.

Shedding light on the geographical distribution, population size and inflorescence coloration variety of Royal Irises (Iris section Oncocyclus) family in West Bank, Palestine

Palestine has rich floristic diversity due to its location, diverse biogeographical zones, and various topographical features. The Royal Irises (Iris section Oncocyclus), are a monophyletic group of herbaceous geophytes, consisting of 33 species, endemic to the Middle East. Within the West Bank of Palestine, three Royal Irises are documented. However, their distribution, population size, and status are not studied comprehensively. This study focused on evaluating the occurrence, distribution range, population size, status, number of flowers, inflorescence coloration variety, and habitats of the vulnerable and endemic Iris haynei, the endangered and sub-endemic Iris lortetii, and the vulnerable and sub-endemic Iris atrofusca. I. lortetii was found in 10 sites within Nablus district, with more than 12625 clones and 25088 flowers flowers recorded. I. haynei were documented in 4 sites within Jenin district, three are new to science, where 10729 clones and 9562 flowers were recorded. I. atrofusca was reported in 13 localities in Tubas and Ramallah districts, where 1853 clones and 8460 flowers were recorded, whereas six locatities are new to science. 12, 12, and 7 unique variations in coloration of inflorescences were observed for I. lortetii, I. atrofusca, and I. haynei, respectively. The results indicate that the population size and the distribution range of the three Royal Irises are larger than previously reported, whereas the documented inflorescences’ coloration variations are unique and considerable. This study sheds light on hotspot occurrence sites of endangered and vulnerable species in Palestine, which can assist in laying adequate conservation actions and management plans in the future.

RELATIONS OF KURDS WITH ARMENIANS (951-1150)

Kurds and Armenians are local peoples of the Middle East. Historically, Armenians lived in the Caucasus and Anatolia, and the Kurds in Upper Mesopotamia and southwest of Iran. Although the places where Kurds and Armenians lived were close to each other, the question of when, where and how the relations between the two communities began has not been answered so far because there is not enough scientific research on this subject. Armenian historians were interested in Armenian-Kurdish relations in the early 19th century and conducted some research. Although some researchers, including N. J. Marr, found the Kurds to be closer to Georgians and Armenians than the Caucasian peoples, this idea was not generally accepted. Since the beginning of the 20th century, Kurdish intellectuals have claimed that the two communities have the same religion, the same lineage, and the same culture, without any cohesive research. However, there is very little information in the Armenian chronicles about the partnership of the two communities. Modern Armenian historians, however, do not consider these assumptions of the Kurds reliable. In this article, an answer was sought to the question of when, where, and how the relations of Kurds with Armenians began in the Middle Ages. Since there are no Kurdish works in our research that describe the early periods of the Kurds; Armenian chronicles, Islamic history sources and the works of modern researchers were used. According to the information given in Armenian chronicles and Islamic sources, Kurdish-Armenian relations seem to have started in the 10th century. This was disclosed through primary sources.

Is military spending converging across middle eastern countries and Turkiye? A comprehensive unit root test analysis

AbstractThe Middle East is a region of chronic insecurity due to internal and external tensions. These tensions and insecurity have made the Middle East one of the world's leading regions in military armaments. This study investigates the stochastic convergence of military burden in 10 selected Middle Eastern countries using comprehensive unit root analysis. Stochastic convergence for each country from 1977 to 2020 is examined using conventional, structural break, nonlinear, and Fourier‐based unit root tests. Empirical results provide strong evidence of convergence with regional averages in Bahrain, Saudi Arabia, and Oman. There is also some evidence of convergence in the case of Israel, Egypt, Kuwait, Lebanon, and Turkiye. However, evidence for the existence of convergence in Iran and Jordan is weak.

Smoking and cluster headache presentation and responsiveness to treatment

BackgroundThough an association between cluster headache (CH) and smoking has been postulated, data from the Middle East region is scarce.Aim of workTo study the relationship between smoking and CH clinical characteristics and responsiveness to therapy in Egypt.MethodologyThis was a prospective cohort hospital-based study conducted on patients with episodic and chronic CH in a tertiary headache clinic in Egypt during the period between 2019 and 2023. Patients were consecutively recruited at the time of their presentation and were followed up for two weeks after initiation of prophylactic treatment and steroids (as transitional therapy).ResultsOf 172 patients with CH recruited, 144 (83.7%) were smokers. Twenty-eight patients (16.3%) had chronic CH. The mean age was 42.08 ± 10.93 (20–66) years, and 131 (76.2%) were males. Smokers had a significantly higher median number of cluster bouts in the past five years (3.0 (IQR2.0–4.0) versus 2.0 (IQR 1.0–2.0)) and worse HIT-6 scores [51.0 (44.0–59.75) versus 41.0 (38.0–41.75)] than non-smokers (p < 0.001). The number of cluster bouts in the past five years was positively correlated with the smoking index (r = 0.249 (p = 0.006) and the smoking duration (in years) (r = 0.392 (p < 0.001)). HIT-6 scores were significantly correlated with the age at smoking onset (r=-0.190, = 0.023), smoking index (r = 0.519, p < 0.001), smoking duration (r = 0.611, p < 0.001), and number of cigarettes consumed per day (r = 0.392, p < 0.001).ConclusionSmoking is significantly correlated with the daily frequency of CH attacks, the frequency of CH bouts in the past five years, and the HIT-6 scores among our cohort.

Changes in Revealed Comparative Advantage in Machinery and Equipment: Evidence for Emerging Markets

The paper computes Balassa’s index of revealed comparative advantage for machinery and equipment (a rough proxy for high-tech goods) for a number of emerging areas (East Asia, South-East Asia, South Asia, Eastern Europe, Latin America, Africa, and the Middle East) and for selected individual countries over some 50 years, from the early 1970s to the early 2020s. The focus is on why some economies were successful in promoting high-tech sectors. As could be expected, experience differs hugely. In some countries, interventionist trade or industrial policies were crucial in fostering comparative advantage. In others, however, the role of policies appears to have been minor and successes were achieved thanks to the free play of market forces (including an important contribution, at least in some countries, coming from foreign direct investment).

Civil Society Participation and Suicide Rates: A Cross-National Analysis

Previous valuable research has examined the effect individual-level social and psychological factors have on suicidality. However, scholarship has yet to investigate the role civil society participation plays in suicide rates cross-nationally. Thus, this study examines the effect civil society participation has on suicide rates in 156 countries from varying levels of development from 2000 – 2019 from Africa, Asia, Europe, Latin America, the Middle East, and North America. When including standard controls and controlling for potential endogeneity, the findings indicate that civil society participation, both political and non-political, has a negative and statistically significant effect on suicide rates. The results suggest that both political and non-political forms of civil society participation may produce positive social and psychological benefits that are associated with lower suicide rates.

“This isn’t a place like Iraq or Afghanistan”: coverage of the Russian invasion of Ukraine and the Middle Eastern other

ABSTRACT The study employs a postcolonial critique of the media coverage during the Russian invasion of Ukraine. By using literature on whiteness and Islamophobia and the need for a postcolonial critique, the author analyzes the hegemonic rhetoric surrounding the Ukrainian refugee crisis in comparison to coverage of violence directed toward brown bodies. The study also juxtaposes a postcolonial critique against vernacular readings of how social media users reacted to the attacks. Thus, the goal is to present trajectories for future studies of whiteness.

Impact of green financial funding on improving the financial efficiency of a sample of companies listed on the Iraq stock exchange

The aim of this research is to identify the impact of green financing on financial efficiency by highlighting the importance of financing green activities in supporting the financial efficiency of banks. In this research, the authors adopted the descriptive analytical method and the statistical method, where (75) questionnaires were distributed to a research sample consisting of three banks: Al-Ahli Bank of Iraq, Middle East Bank, and North Bank. The questionnaires were transcribed and analyzed using Microsoft Excel. The research concluded that green financing contributes to financing sustainable activities and protecting the environment. The research also found that the interest in green financing enhances the efficiency of bank management in facing risks, while green financing has a weak impact on the performance and financial efficiency of banks. The research recommends that banks focus on sustainability and renewable energy sectors, increase investors' and customers' awareness of green activities, and emphasize the importance of green financing in achieving sustainable development.

Spontaneous resolution of synovial lumbar cyst presented with severe symptoms: a case report

IntroductionSpinal cysts have traditionally been treated with surgery since it was first described in 1950. However, there have been rare instances where these cysts have resolved on their own without the need for surgical intervention. Here, we discuss the 27th reported case of such spontaneous resolution in the medical literature and delve into the details of this unique case.Case presentationThis report details a rare case of a 58-year-old Middle Eastern female who suffered from severe radicular and lumbar pain. Radiological study showed the presence of a cyst in the lumbar column. Noninvasive treatment was chosen after ensuring that there were no other symptoms requiring surgery. The patient showed gradual improvement over the course of 12 months, after which the pain completely disappeared.DiscussionThe surgical approach is currently the main treatment for spinal cysts, but spontaneous resolution, despite its rarity, may be worth considering as a preferred therapeutic approach in the future. This avenue has not been thoroughly explored or studied. Due to the etiology of these cysts and their location within mobile joints, a longer period of conservative management including rest and physical therapy may play a pivotal role in promoting natural resolution.ConclusionConservative treatment of cysts should continue for at least 8 months, using painkillers and physical therapy without lumbar bracing. Surgery remains the most effective means of treatment to date. Further research is needed to validate and establish standardized treatment protocols.

A Manuscript of the Arabian Nights and Its Journey to Cambridge

Abstract Cambridge University Library holds an Arabic manuscript of The Thousand and One Nights (Ms Qq.106–109). The library records it as entering the collection in 1819 and codicological evidence shows that the manuscript was copied in Cairo in the early 19th century. This paper discusses the complex narrative of its acquisition, including the roles played by prominent travellers and collectors. The significance of the text of the ‘Nights’ and its popularity in England and Europe are also examined as are the factors that made the Arabic text of this work much sought-after at the time. The influence of the contemporary political situation, the conditions of travel in the Middle East, and the individuals involved with the text’s acquisition are described, focusing on those with a Cambridge connection. A detailed analysis of the activities and twists of fate resulting in the acquisition of this particular manuscript are traced in contemporary sources.

Chechen Diaspora in the countries of the Middle East: on the issue of generational continuity and socio-political dynamics of communities

The article is concerned with little-studied dynamics of the Chechen and, more broadly, North Caucasian Diaspora in Jordan, Syria and Turkey, starting with the emergence of these communities in the 19th century during the era of the Ottoman Empire. The article traces a slow change in the character of these diasporic communities from the “exodus” from the Russian Empire to the building up of international relations with the Chechen Republic in the 21st century on the basis of “cultural similarity” and the importance of the idea of an ideal ancestral home. The article argues that the Diaspora changed its character from a refugee Diaspora to an imperial Diaspora during the Ottoman Empire, and then became a “cultural Diaspora” with predominant narratives of cultural and geographical proximity with the country of origin a century after the resettlement. The article also argues that cultural and geographical similarity leads to the importance of ethnopolitical factor in international relations and diasporic politics.

Skillful Long-Lead Seasonal Predictions in the Summertime Northern Hemisphere Midlatitudes

Abstract In contrast to boreal winter when extratropical seasonal predictions benefit greatly from ENSO-related teleconnections, our understanding of forecast skill and sources of predictability in summer is limited. Based on 40 years of hindcasts of the Canadian Seasonal to Interannual Prediction System, version 3 (CanSIPSv3), this study shows that predictions for the Northern Hemisphere summer surface air temperature are skillful more than 6 months in advance in several midlatitude regions, including eastern Europe–Middle East, central Siberia–Mongolia–North China, and the western United States. These midlatitude regions of statistically significant predictive skill appear to be connected to each other through an upper-tropospheric circumglobal wave train. Although a large part of the forecast skill for the surface air temperature and 500-hPa geopotential height is attributable to the linear trend associated with global warming, there is significant long-lead seasonal forecast skill related to interannual variability. Two additional idealized hindcast experiments are performed to help shed light on sources of the long-lead forecast skill using one of the CanSIPSv3 models and its uncoupled version. It is found that tropical ENSO-related sea surface temperature (SST) anomalies contribute to the forecast skill in the western United States, while land surface conditions in winter, including snow cover and soil moisture, in the Siberian and western U.S. regions have a delayed or long-lasting impact on the atmosphere, which leads to summer forecast skill in these regions. This implies that improving land surface initial conditions and model representation of land surface processes is crucial for the further development of a seasonal forecasting system. Significance Statement Useful seasonal predictions in the boreal summer midlatitude regions are of great value. In this study, we show that predictions for the boreal summer season are skillful more than 6 months in advance in several midlatitude regions, including eastern Europe–Middle East, central Siberia–Mongolia–North China, and the western United States. The forecast skill in these regions is associated with a circumglobal teleconnection atmospheric circulation pattern. Sources of the long-lead forecast skill include the global warming–related trend and anomalies in the ocean and land surface initial conditions. It is found that the wintertime snow cover and soil moisture in the Siberian and western U.S. regions have a delayed or long-lasting impact on the atmosphere, which leads to summer forecast skill.

Modeling health outcomes of air pollution in the Middle East by using support vector machines and neural networks

This study investigates the impact of air pollution on health outcomes in Middle Eastern countries, a region facing severe environmental challenges. As such, these are important in an effort to add up to policy-level as well as interventional changes that can be put in practice in the area of public health. Numeration analysis and association with health parameters was carried out by using Analytical tools such as, AIR Data, ARIMA,ANN, SVM and Exponential smoothing. Amongst the models, Support Vector Machine came again on top, with high accuracy yielding Mean Absolute Percentage Error of approximately 1%. Mortality of Air pollution in Qat from the case of Mortality of Air Pollution in Qatar is 959 while Auto regressive Integrated Moving average is 11.096, Exponential Smoothing 9.892 and Artificial Neural Networks are the source of inspiration for the development of this paper 4.61. The above perceptions indicate that there is need to adapt modeling strategies depending on the context and establish that it is possible to implement ML models in public health planning basket. This paper publishes the methodological frameworks for the purpose of modeling and analysis of the EHDs and serves as policy prescription for the policy makers to intending to reduce the effects of air borne pollution on health.

Relationship Between Depression and Medication Adherence Among Chronic Disease Patients in the Middle East

Application of electrospray triple quadrupole mass spectrometry in assessing thalassemia in a population.

Thalassemia is widely prevalent in Asian countries and the Middle East region of the world. While the prevalence of α thal is around 5-20% in the population, the incidence of β thal is around 3-4%. The available data on thalassemia in Indians is based on chromatographic or electrophoretic techniques. The present study demonstrates the utility of mass spectrometry in detecting thalassemia in a small, healthy population from Tiptur, Karnataka. The study included a population of 315 individuals, spanning both children and adults, with ages ranging from 4 to 76 years. EDTA whole blood was collected after obtaining their written consent. The intensities of various globin chains were measured using a triple quadrupole mass spectrometer. The ratio of the peak areas of globin chains (α/β, δ/β (%)) served as biomarkers to detect thalassemia. Thirty random samples of α thalassemia were analyzed using GapPCR. The prevalence of a thal is 21.65% (68/314) based on α/β (< =0.8) and the prevalence of β thal is 3.8% (12/314) based on δ/β (%) (> =11.0). GapPCR detected three heteromutants of α deletion, one mutation in the HBA1 gene, and one a triplication (16.7%, 5/30). One sample was excluded from the analysis due to the presence of a variant. The utility of mass spectrometry for screening thalassemia in a population is demonstrated. The higher occurrence of α-thalassemia in the studied population underscores the importance of screening for thalassemia in regions with reportedly high prevalence rates.

A Critique of Marvin G. Weinbaum's Review of "The Decline and Fall of Republican Afghanistan Book"

This paper examines Marvin G. Weinbaum's critique of "The Decline and Fall of Republican Afghanistan" by Ahmad Shuja Jamal and William Maley. Weinbaum's review, published in the Middle East Journal, offers a comprehensive analysis of the book's structure, strengths, and weaknesses. While Weinbaum effectively highlights the book's deep analysis, historical context, and scholarly rigor, this critique identifies several areas where his review could be further strengthened. These include a more critical examination of the sources used, a deeper exploration of the political and social impacts, a sociological analysis of Afghanistan's twenty-year war, and a comprehensive analysis of the authors' methodology. Additionally, this article addresses significant discussions such as the lack of localization in content, the process of Afghanistan's revitalization, and the impact of Pashtunism on the country's political and social dynamics. By incorporating these perspectives, the critique aims to provide a more comprehensive understanding of the factors contributing to the fall of Republican Afghanistan and the complexities surrounding its recent history.

Global, regional, and national burdens of acne vulgaris in adolescents and young adults aged 10-24 years from 1990 to 2021: a trend analysis.

Acne vulgaris is a common skin condition affecting adolescents and young adults worldwide, yet data on its burden and trends remain limited. We aimed to investigate trends in the burden of acne vulgaris among adolescents and young adults aged 10-24 years at global, regional, and national levels. We retrieved data from the Global Burden of Disease Study (GBD) 2021 for individuals aged 10-24 years in 204 countries and territories from 1990 to 2021. We analyzed the numbers, age-standardised rates, and average annual percentage changes (AAPCs) of the prevalence, incidence, and disability-adjusted life-years (DALYs) for acne vulgaris at the global, regional, and national levels. Additionally, we examined these global trends by age, gender, and Socio-demographic Index (SDI). Globally, the age-standardised prevalence rate of acne vulgaris among adolescents and young adults increased from 8,563.4 per 100,000 population (95% UI 7,343.5-9,920.1) in 1990 to 9,790.5 (95% UI 8,420.9-11,287.2) per 100,000 population in 2021, with an AAPC of 0.43 (95% CI 0.41-0.46). The age-standardised incidence rate and age-standardised DALY rate also showed a similar upward trend. Regionally, Western Europe had the highest age-standardised prevalence, incidence, and DALY rates, while North Africa and the Middle East had the largest increase in these rates. By SDI quintile, the high SDI region had the highest age-standardised prevalence, incidence, and DALY rates from 1990 to 2021, whereas the low-middle SDI region had the lowest burden of acne vulgaris but experienced the most significant increase in these rates. Globally, the age-standardised prevalence rate of acne vulgaris in 2021 was approximately 25% higher in females than in males (10,911.8 per 100,000 population vs. 8,727.8 per 100,000 population). Among all age groups, adolescents aged 15-19 years had the highest age-specific prevalence rate, while adolescents aged 10-14 years experienced the largest increase from 1990 to 2021 (AAPC = 0.50, 95% CI 0.48-0.52). The burden of acne vulgaris among adolescents and young adults has continued to increase in nearly all countries since the 1990s. Managing this condition remains a significant challenge, necessitating more effective and targeted interventions to control the acne burden.

Prevalence of Thyroid Dysfunction Disorders among Adult Populations in the Middle–East: A Systematic Review and Meta-analysis

Prevalence of Thyroid Dysfunction Disorders among Adult Populations in the Middle–East: A Systematic Review and Meta-analysis

Association of circulating visfatin level and metabolic fatty liver disease: An updated meta-analysis and systematic review.

The rate of incidence of metabolic dysfunction-related fatty liver disease (MAFLD) has rapidly increased globally in recent years, but early diagnosis is still a challenge. The purpose of this systematic review and meta-analysis is to identify visfatin for early diagnosis of MAFLD. We strictly adhered to the relevant requirements of Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The systematic search was conducted in 7 sources (PubMed, Embase, Cochrane Library, CNKI, Wanfang, CBM, and ClinicalTrials.gov) until February 2024. The meta-analysis was performed using Stata 12. Outcomes were expressed in the form of standardized mean difference (SMD) and 95% confidence interval and were analyzed using meta-analysis. The results showed that there was no significant difference in circulating visfatin levels between patients with MAFLD and controls (SMD = 0.13 [-0.34, 0.60]). However, the outcomes indicated that the level of circulating visfatin was significantly higher in MAFLD patients in the Middle Eastern subgroup (SMD = 0.45 [0.05, 0.85]) and in the obese patient subgroup (SMD = 1.05 [0.18, 1.92]). No publication bias was detected, and sensitivity analysis confirmed the stability of the outcomes. The serum visfatin levels of MAFLD patients did not differ significantly from those of controls. However, visfatin concentrations in serum were statistically higher within Middle Eastern or obese MAFLD patients compared to controls. There is a need for further research to investigate visfatin's potential as a biomarker for MAFLD.
