Global prevention of gastric cancer needs to increase its level of *** prevention strategy should include all stages of primary and secondary *** necessary steps to prevent gastric cancer are the following:Maintaining a healthy lifestyle and diet,avoiding smoking and alcohol;serological screening of Helicobacter pylori infections and eradication;serological screening of atrophic gastritis in the population over 45 years of age and identification of severe atrophic gastritis with a high risk of developing gastric cancer;verification of atrophic gastritis and precancerous changes in the gastric mucosa using modern endoscopic(confocal laser endomicroscopy,narrow-spectrum imaging,and magnifying endoscopy)and morphological methods among patients with severe atrophic gastritis who were identified using serological screening;treatment of patients with atrophic gastritis during diagnosis verification;annual endoscopic and morphological monitoring of patients with atrophic gastritis during permanent treatment;annual serological monitoring of patients with atrophic gastritis who refused endoscopic and morphological monitoring;and radical treatment of patients with verified early gastric *** to implement the algorithm for the global strategy for the prevention of gastric cancer(protocol of practical recommendations)are:State,government,and municipal programs;departmental programs of health departments;family doctors for patients who have a contract at the initiative of the doctor;family doctors for patients with a contract at the patient’s initiative;and within private healthcare system where both doctors and patients can initiate the implementation of algorithm.

This paper celebrates Professor Yongqi GAO's significant achievement in the field of interdisciplinary studies within the context of his final research project Arctic Climate Predictions: Pathways to Resilient Sustainable Societies-ARCPATH(https://***/en/projects/finished-projects/arcpath). The disciplines represented in the project are related to climatology, anthropology, marine biology, economics, and the broad spectrum of social-ecological studies. Team members were drawn from the nordic countries, Russia, China, the United States, and Canada. The project was transdisciplinary as well as interdisciplinary as it included collaboration with local knowledge holders. ARCPATH made significant contributions to Arctic research through an improved understanding of the mechanisms that drive climate variability in the Arctic. In tandem with this research, a combination of historical investigations and social, economic, and marine biological fieldwork was carried out for the project study areas of Iceland, Greenland, norway, and the surrounding seas, with a focus on the joint use of ocean and sea-ice data as well as social-ecological drivers. ARCPATH was able to provide an improved framework for predicting the near-term variation of Arctic climate on spatial scales relevant to society, as well as evaluating possible related changes in socioeconomic realms. In summary, through the integration of information from several different disciplines and research approaches, ARCPATH served to create new and valuable knowledge on crucial issues, thus providing new pathways to action for Arctic communities.

The Islamic Republic of Iran’s principal rivers are the Karun and Shatt al-Arab. The Karun River has a 950 km length. The Karun River starting point is the convergence of the Amand, Kuhrang, and Bazoft rivers. From their headwater sources in the mountains of eastern Iran, these rivers descend through valleys and gorges and flow into the plains of Iran. The Shatt al-Arab River drains an area of 879,790 square kilometers which includes land in Iran, Syria, Türkiye, Kuwait, and Iraq. The Karun joins Shatt al-Arab 110 km downriver from the confluence of the Euphrates and Tigris Rivers and flows 85 km into the Persian Gulf. The Karun river flows in a southwestern direction through the central plain and provides about 10 per cent of the water balance of Iran’s largest wetland, the Shadegan, which includes permanent marshes, lakes, and riparian habitats. The article summarizes a vast array of publications on the stated topic and this civilizationally important region in order to draw additional attention to its interdependent environmental, economic and political problems the successful resolution of which is only possible with the participation of the entire research community.

The Volga River flows entirely through Russia and the watershed includes three of the country’s ten largest cities. The river is the longest in Europe and western Russia’s principal waterway. The Volga River basin is home to approximately half of Russia’s population and occupies almost two-fifth of European Russia. It covers much of the Volga region and stretches 3530 kilometers from its source in the Valdai Hills to the Caspian Sea, the world’s largest inland water body. Its economic, cultural, and historic importance makes it one of the world’s greatest rivers. The Volga basin makes up 8 percent of the Russian territory. Stalingrad, located on the banks of the Volga River, has been described as the site of the greatest de-feat in the history of the German Army. It is often identified as the turning point on the Eastern Front of WWII, in the war against Germany, and in the entire WWII. The meeting point of the Eurasian Civilization was historically the Volga River. The river has some of the world’s largest reservoirs and is a major source of livelihood for millions of people. Many factories and cities empty their waste including sewage, industrial waste, fertilizers, and pesticides into the Volga River. Pollutants tend to settle in the reservoirs and contain several meters of heavily contaminated muck. The primary objectives are to assess lessons learned, manage, and restore the Volga River system lifeline in Russia.

Optical metasurfaces, comprising subwavelength quasi-planar nanostructures, constitute a universal platform for manipulating the amplitude, phase, and polarization of light, thus paving a way for the next generation of highly integrated multifunctional optical devices. In this work, we introduce a reflective metasurface for the generation of a complete(angularly resolved) polarization set by randomly interleaving anisotropic plasmonic meta-atoms acting as nanoscale wave *** the proof-of-concept demonstration, we achieve multidirectional beam-steering into different polarization channels forming a complete set of polarization states, which can also be dynamically altered by switching the spin of incident light. The developed design concept represents a significant advancement in achieving flat polarization optics with advanced functionalities.
