Pulmovermis cyanovitellosus Coil and Kuntz, 1960 is a species of hemiurid trematode that localizes in the lung of sea snakes, an unusual trait for this group of parasites. Recent molecular phylogenetic studies based on 28S rRNA gene sequences have shown that this species is closely related to members of the genus Lecithochirium Lühe, 1901. This finding is unexpected given that Pulmovermis Coil and Kuntz, 1960 and Lecithochirium are currently classified in different subfamilies of Hemiuridae (Pulmoverminae Sandars, 1961 vs.

Digeneans of the family Notocotylidae differ from other digeneans in their peculiar eggs. The eggs feature a pair of long filaments extending from their poles, and their contents differ significantly from what we expect to observe in the eggs of digeneans. Instead of a ciliated miracidium larva, the notocotylid egg contains a tiny few-celled mother sporocyst.

Background: Patients with Gaucher disease (GD) require continual monitoring; however, lack of specific disease biomarkers was a significant challenge in the past. Glucosylsphingosine (lyso-Gb1) has been shown to be a reliable, key, specific, and sensitive biomarker for diagnosis, prognosis, and treatment response in clinical studies of patients with GD. We evaluated the change in lyso-Gb1 concentration over time following enzyme replacement therapy in patients with confirmed GD using real-world data from the Gaucher Outcome Survey disease registry.

With the development of next-generation sequencing (NGS) technologies it became possible to simultaneously analyze millions of variants. Despite the quality improvement, it is generally still required to confirm the variants before reporting. However, in recent years the dominant idea is that one could define the quality thresholds for "high quality" variants which do not require orthogonal validation.

Purpose: To analyze levels of salivary steroids, including 17-OH-progesterone (17-OHP), androstenedione, dehydroepiandrosterone, cortisol, cortisone, progesterone, testosterone, and estradiol, in patients with acute central serous chorioretinopathy (CSCR) patients.
Methods: Acute CSCR patients and healthy individuals were included in this observational case-control study. Levels of salivary steroids were determined by high-performance liquid chromatography with tandem mass spectrometry detection.

Chronic non-specific low back pain (CNSLBP) is a debilitating condition that affects millions of people worldwide, significantly impacting quality of life and imposing a substantial socioeconomic burden. Traditional treatment approaches often rely on a one-size-fits-all strategy, failing to account for individual variations in pathophysiological mechanisms, drivers, and the principles of personalized medicine. Furthermore, an overemphasis on biomechanical findings from imaging may lead to ineffective interventions and unnecessary surgical procedures, obscuring other important factors that contribute to pain perception.

The aim of the present study was to obtain new metal complexes of citrus pectin with cobalt ions based on potassium polygalacturonate and to prepare a new pharmacological composition (PC) PGKCo: PGNaCo (1:1) with antitumor activity based on potassium cobalt polygalacturonate (PGKCo) and sodium cobalt polygalacturonate (PGNaCo). The study of the effect of PGKCo, PGNaCo and PC on the cell viability of tumor cell lines of different genesis in vitro showed that the obtained compounds are soluble in water and exhibit selective cytotoxic activity against the tumor cell lines of human lung carcinoma A549, breast adenocarcinoma MCF-7 and cervical carcinoma M-HeLa, with no significant toxic effect on normal human cells. The possible mechanism of action of the investigated PC on M-HeLa cancer cells was investigated.

The radionuclide contamination of the environment is an abiotic stress factor that influences biological systems. Plants growing in contaminated areas for many generations provide a unique opportunity to study adaptive strategies aimed at maintaining homeostasis under elevated radiation levels. Using non-targeted metabolomics approaches, we investigated the metabolomic profiles of Achillea millefolium L.

Background: Prolgolimab is an IgG1 anti-PD-1 monoclonal antibody with the Fc-silencing 'LALA' mutation. The phase III DOMAJOR study assessed efficacy and safety of prolgolimab in combination with pemetrexed and platinum-based chemotherapy vs placebo in combination with pemetrexed and platinum-based chemotherapy as first-line treatment for advanced non-small cell lung cancer (NSCLC).
Methods: 292 patients with advanced non-squamous NSCLC were randomized 1:1 to receive 4 cycles of pemetrexed, platinum-based drug and either prolgolimab (3 mg/kg Q3W) or placebo followed by prolgolimab/placebo with pemetrexed until disease progression or toxicity (≤36 months).

The stone marten (Martes foina) is an important species for cytogenetic studies in the order Carnivora. ZooFISH probes created from its chromosomes provided a strong and clean signal in chromosome painting experiments and were valuable for studying the evolution of carnivoran genome architecture. The research revealed that the stone marten chromosome set is similar to the presumed ancestral karyotype of the Carnivora, which added an additional value for the species.

Reactive oxygen species (ROS) produced by NADPH oxidase promote contraction of peripheral arteries, which is especially pronounced in early postnatal period in comparison to adulthood, but the mechanisms of such vasomotor influence are poorly understood. We tested the hypothesis that Rho-kinase and protein kinase C (PKC) mediate procontractile influence of NADPH oxidase derived ROS in peripheral artery of early postnatal rats. In addition, we evaluated the involvement Src-kinase and L-type voltage-gated Ca channels (LTCC) into procontractile influence of ROS, produced by NADPH oxidase, because of their known interplay with Rho-kinase and PKC pathways.

In the energy range of 3-20 keV covered by the NuSTAR, the obtained limits reach the bottom edge of theoretical predictions of realistic models where sterile neutrinos are produced in the early Universe. Only a small region is left to explore, if the sterile neutrinos form the entire dark matter component.

The spin-exotic hybrid meson π_{1}(1600) is predicted to have a large decay rate to the ωππ final state. Using 76.6 pb^{-1} of data collected with the GlueX detector, we measure the cross sections for the reactions γp→ωπ^{+}π^{-}p, γp→ωπ^{0}π^{0}p, and γp→ωπ^{-}π^{0}Δ^{++} in the range E_{γ}=8-10 GeV.

Using the e^{+}e^{-} collision data collected with the BESIII detector operating at the BEPCII collider, at center-of-mass energies from the threshold to 4.95 GeV, we present precise measurements of the cross section for the process e^{+}e^{-}→D_{s}^{+}D_{s}^{-} using a single-tag method. The resulting cross section line shape exhibits several new structures, thereby offering an input for a future coupled-channel analysis and model tests, which are critical to understand vector charmonium-like states with masses between 4 and 5 GeV.

Adapting biological systems for nanoparticle synthesis opens an orthogonal Green direction in nanoscience by reducing the reliance on harsh chemicals and energy-intensive procedures. This study addresses the challenge of efficient catalyst preparation for organic synthesis, focusing on the rapid formation of palladium (Pd) nanoparticles using bacterial cells as a renewable and eco-friendly support. The preparation of catalytically active nanoparticles on the bacterium VKM B-3302 represents a more suitable approach to increase the reaction efficiency due to its resistance to metal salts.

Woody and herbaceous plants are the main components of global terrestrial ecosystems, and their growth, adaptation and survival depend largely on the metabolism of shoots and roots. Therefore, understanding size-scaling of metabolic rates in woody and herbaceous plants, and in shoots and roots, is a fundamental issue in ecology. However, few empirical studies have examined metabolic scaling exponents across a wide range of plant sizes.
