[Cost-effectiveness of using rubidium-82 chloride perfusion PET for planning myocardial revascularization procedures].

Objective: The aim of this study is to evaluate the cost-effectiveness, diagnostic accuracy, clinical outcomes, and radiation exposure associated with rubidium-82 chloride perfusion PET.

Methods: A comprehensive literature search up to October 2024 was conducted to identify key studies assessing the use of rubidium-82 chloride perfusion PET/CT in ischemic heart disease (IHD). These studies included economic analyses, evaluations of diagnostic accuracy, and comparisons with other imaging modalities such as single-photon emission computed tomography (SPECT), stress echocardiography, and invasive coronary angiography.

A high-altitude population of Hyperboreomyzon polaris (Hirudinea: Glossiphoniidae) in Altai Mountains, South Siberia, Russia.

Hyperboreomyzon polaris Bolotov, Eliseeva, Klass & Kondakov, 2022 (Hirudinea: Glossiphoniidae) is an enigmatic freshwater leech that was recently described based on three specimens from two remote regions of the Eurasian Arctic, that is, the Kolguev Island and Putorana Plateau, Russia. Later on, misidentified historical samples of this species were discovered in the Hirudinea collection of Zoological Institute of the Russian Academy of Sciences (St. Petersburg, Russia).

Integrative phylogenetic, phylogeographic and morphological characterisation of the Unio crassus species complex reveals cryptic diversity with important conservation implications.

The global decline of freshwater mussels and their crucial ecological services highlight the need to understand their phylogeny, phylogeography and patterns of genetic diversity to guide conservation efforts. Such knowledge is urgently needed for Unio crassus, a highly imperilled species originally widespread throughout Europe and southwest Asia. Recent studies have resurrected several species from synonymy based on mitochondrial data, revealing U.

: excerpt from the diary with an introduction.

The following text is an excerpt from , a fictional diary written by Evgeny Shtorn, poet and activist, from his experience of seeking asylum. Shtorn had to flee Russia due to the government's hostile policies toward both queer sexualities and political dissent right after he was interviewed by the Russian secret police FSB in 2018. The run for life and liberty brought him to the utmost end of Western Europe, Ireland.
