Impact of global environmental changes on the range contraction of Eurasian moose since the Late Pleistocene.

Sci Total Environ

December 2024

Department of Palaeozoology, Faculty of Biological Sciences, University of Wrocław, Sienkiewicza 21, 50-335 Wrocław, Poland.

Climatic oscillations are considered primary factors influencing the distribution of various life forms on Earth. Large species adapted to cold climates are particularly vulnerable to extinction due to climate changes. In our study, we investigated whether temperature increase since the Late Pleistocene and the contraction of environmental niche during the Holocene were the main factors contributing to the decreasing range of moose (Alces alces) in Europe.

Scar-related ventricular tachycardia (VT) commonly results from scarring in the myocardium, principally produced by antecedent myocardial infarction, cardiomyopathy, or prior cardiac surgery. The resultant arrhythmogenic substrate from scarred tissue and the alteration of normal cardiac electrical conduction predispose patients to reentrant circuits, followed by VT. This literature review synthesizes current research on pathophysiology, diagnostic methods, and treatment modalities of scar-related VT.

Article Synopsis
  • - HfZrO (HZO) is gaining popularity for its strong ferroelectric properties, small size (less than 10 nm), and compatibility with CMOS technology, which is essential for modern electronics.
  • - Traditional HZO films require improvements to meet demands for reduced thermal budget and lower power use, leading to the introduction of a middle layer (ML) strategy to enhance features like ferroelectricity and control the wake-up effect in ferroelectric capacitors.
  • - The study found that using a ZrO middle layer led to impressive results, achieving a high remnant polarization and very low wake-up ratios, while also confirming the capacitor's reliability over millions of cycles.

Article Synopsis
  • - The text discusses the importance of detecting Salmonella in food due to its association with salmonellosis outbreaks, highlighting the use of immunochemical methods like ELISA for detection.
  • - Traditionally, commercial ELISA kits focus on detecting lipopolysaccharide (LPS) from Salmonella using a sandwich technique, but the authors aimed to create a competitive ELISA for improved sensitivity.
  • - The newly developed competitive ELISA test shows enhanced sensitivity, consistent results, and can detect any Salmonella serotype through a method that uses a BSA-LPS conjugate and specific monoclonal antibodies, contributing to better food safety and public health.

Complement factor H in molecular regulation of angiogenesis.

Med Rev (2021)

October 2024

Laboratory of Translational Medicine in Microvascular Regulation, Institute of Microvascular Medicine, Medical Research Center, The First Affiliated Hospital of Shandong First Medical University & Shandong Provincial Qianfoshan Hospital, Jinan, Shandong Province, China.

Angiogenesis, the process of formation of new capillaries from existing blood vessels, is required for multiple physiological and pathological processes. Complement factor H (CFH) is a plasma protein that inhibits the alternative pathway of the complement system. Loss of CFH enhances the alternative pathway and increases complement activation fragments with pro-angiogenic capacity, including complement 3a, complement 5a, and membrane attack complex.

Article Synopsis
  • Drug resistance in cancer chemotherapy is a major issue, with cancer cells often shifting to fatty acid metabolism to evade treatment.
  • The researchers created a drug called folate-polySia (FpSA) that induces microcalcification in cervical cancer cells resistant to cisplatin, leading to decreased fatty acid uptake and increased glycolysis.
  • The combination of cisplatin and FpSA not only inhibited tumor growth but also improved survival rates in mice, suggesting a new strategy to tackle chemotherapy-resistant tumors by reprogramming cancer cell metabolism.

  • This study investigated how irradiation from krypton and helium ions affects the structure and composition of high-entropy alloys (HEAs) at room temperature, specifically CoCrFeNi and CoCrFeMnNi.
  • Findings showed that while elemental distribution remained stable, blisters formed on nickel surfaces due to the irradiation process, with large ones averaging 3.8 μm in diameter.
  • The research noted significant changes in lattice parameters, stress levels (compressive and tensile), and dislocation densities in the HEAs post-irradiation, indicating differences in material responses between the two alloys.

Abstract-Myxomycetes are amoeboid fungus-like organisms (Amoebozoa) with a unique life cycle characterized by a great morphological diversity of fruiting bodies. Due to the similarity of these structures to the fruiting bodies of some representatives of Ascomycota and Basidiomycota, myxomycetes have been classified as fungi since the first known scientific description in 1654. Only in the 19th century, when their life cycle was studied, did the difference of this group from fungi become clear.

  • The study focuses on the importance of the microvessel compartment in the tumor environment of endometrioid adenocarcinoma (EA) and explores the implications of vasculogenic mimicry (VM), CD146, and CD105 microvessel density on clinical prognosis.
  • A total of 188 EA cases were examined using specific staining techniques, revealing that higher levels of VM channels and CD146/CD105 microvessels were linked to worse prognoses.
  • The findings suggest that these factors could serve as independent indicators of prognosis and potential targets for antiangiogenic therapy, although further research is needed for confirmation.

Article Synopsis
  • The olfactory nerve (cranial nerve I) primarily projects to the same side of the brain, but how it processes smells can vary depending on the task and type of odor stimulus.
  • A study involving 20 young adults with normal smell used fMRI to observe brain activity while participants experienced scents through one nostril, both passively and actively.
  • Results showed that, regardless of nostril and stimulation type, both primary and secondary brain areas related to smell were activated symmetrically, indicating that pure odors are processed bilaterally in the absence of cognitive demands.

Article Synopsis
  • - A multifunctional Cu-doped CaO nanoreactor was created for breast cancer treatment, incorporating glucose oxidase (GOx) and disguised with a folic acid-coated cell membrane.
  • - This nanoreactor promotes calcium overload to damage mitochondria and "starves" tumor cells by depleting glucose, while generating highly toxic hydroxyl radicals that enhance the effectiveness of the treatment.
  • - The modified red blood cell membranes allow for both active and passive targeting of tumors, improving the delivery and retention time of the nanoreactor at cancer sites for over 48 hours.

Background: In Europe, mortality rates from noncommunicable diseases (NCDs) among persons 30-69 years of age ("NCD premature mortality rates") have declined significantly, except in twelve countries of Eastern Europe and Central Asia, namely Armenia, Azerbaijan, Belarus, Georgia, Kazakhstan, Kyrgyzstan, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine and Uzbekistan. Data on long-term trends in NCD mortality in these countries are limited. We analyzed NCD premature mortality rates, identified change points in NCD mortality trends and forecasted how likely countries are to achieve the global NCD targets, stratified by gender and NCD type.

One of the most significant limitations of photodynamic therapy is its reduced efficacy in hypoxic microenvironments, which are typical of the majority of tumors. This work demonstrates that indolenine heptamethine cyanines with different substituents in the polymethine chain and at the terminal heterocycles are effective superoxide generators that can be activated in the near-infrared range. The introduction of an indene moiety into the polymethine chain results in a significant enhancement in photostability compared to dyes with a cyclohexene moiety or an unsubstituted polymethine chain.

The dataset presents a 43 year-long reanalysis of pollen seasons for three major allergenic genera of trees in Europe: alder (Alnus), birch (Betula), and olive (Olea). Driven by the meteorological reanalysis ERA5, the atmospheric composition model SILAM predicted the flowering period and calculated the Europe-wide dispersion pattern of pollen for the years 1980-2022. The model applied an extended 4-dimensional variational data assimilation of in-situ observations of aerobiological networks in 34 European countries to reproduce the inter-annual variability and trends of pollen production and distribution.
