Sweet Aging : Glycocalyx and Galectins in CNS Aging and Neurodegenerative Disorders

Aging and aging-related neurodegenerative disorders, such as Alzheimer’s disease, are characterized by chronic inflammation that progressively damages nervous tissue within the central nervous system (CNS). In addition to cytokines, lectin-like carbohydrate recognition molecules play a critical role in modifying cellular communication during inflammation. Among these, galectins—particularly anti-i

Low-dimensional dynamics of globally coupled complex Riccati equations : Exact firing-rate equations for spiking neurons with clustered substructure

We report on an exact theory for ensembles of globally coupled, heterogeneous complex Riccati equations. A drastic dimensionality reduction to a few ordinary differential equations is achieved for Lorentzian heterogeneity. By applying this technique, we obtain low-dimensional firing-rate equations for populations of spiking neurons with a clustered substructure.

Seasonal dynamics and nutrient controls of biogenic silica in Baltic Sea surface microplankton and picoplankton communities

In recent years, new contributors to the marine silica cycle have emerged, including pico-sized phytoplankton (3 µm) in the dissolved silica-replete Baltic Sea via biweekly time series samplings spanning 2 years. Time series data showed that the large changes in bSi standing stock in the Baltic Proper were primarily related to microplankton biomass and community composition. Meanwhile, picoplankto

Cold-blooded culture? Assessing cultural behaviour in reptiles and its potential conservation implications

It is becoming clear that the cognition of a species plays an important role in successful conservation, with cultural processes being a fundamental part of this. However, in contrast to mammals and birds, very little is known about cultural processes (and the social learning that underlies these) in reptiles. Here, we summarize the current state of knowledge, consider why this information is so l

Distinct Signatures of Chromosomal Involvement in 59 251 Translocations Across 58 Tumor Types. A Novel Perspective

Chromosomal translocations are key events in cancer, driving oncogenesis by disrupting and deregulating critical genes. While specific tumor-associated translocations are well studied, the frequencies and distributions of most remain unknown. Additionally, the role of chromosomal reshuffling in translocations has received little attention. This study presents data on the chromosomal involvement in

Excipient effect on phenol-induced precipitation of human growth hormone and bovine serum albumin

The aim of this study was to investigate the impact of phenol on the precipitation of bovine serum albumin (BSA) and human growth hormone (hGH), in the presence of other excipients frequently used in biological drugs for parenteral delivery. The focus of the study lieson incompatibilities observed in multidose formulations containing non-ionic surfactants and preservatives. Previous research has s

Epidemiology of respiratory syncytial virus and its subtypes among cases of influenza like illness and severe acute respiratory infection : findings from nationwide sentinel surveillance in Ethiopia

Background: Data in Ethiopia on the epidemiology of Respiratory Syncytial Virus (RSV) and subtypes among influenza-like illness (ILI) and severe acute respiratory infections (SARI) cases is limited. Here, we assessed the epidemiology of RSV and its subtypes among the pediatric and adult ILI /SARI cases in Ethiopia. Methods: We conducted prospective, multicenter facility-based study from May 2023 t

Septic arthritis score (SAS) - a novel clinical prediction model for the probability of septic arthritis in the adult native knee

BACKGROUND: Patients presenting with an acutely painful swollen joint represent a diagnostic challenge. We aimed to develop a clinical prediction model for septic arthritis (SA) in the adult native knee.METHODS: We screened all synovial cultures in south Sweden in 2020 and 2021. We included cultures taken in the emergency department from adults' native knees where SA was considered a differential

Estimating charging infrastructure demand for electric vehicles : a systematic review

Establishing robust charging infrastructure is crucial for electric vehicle (EV) adoption. This study addresses the lack of systematic literature reviews examining the global charging infrastructure research landscape with a comprehensive review of English literature published between 2017 and 2023. We screened 12237 records, and analyzed 137 peer-reviewed and 31 grey literature studies. Findings

Experimental Demonstration of a Spectral Fingerprint for the Saddle and Inverted Conformations of Porphyrins on Copper

Combined density functional theory (DFT) and X-ray standing wave (XSW) studies have previously provided evidence for the preferential adoption of an inverted conformation of 2H-TPP on Cu(111) in contrast to the saddle conformation usually favored by porphyrin molecules adsorbed on metals. We experimentally demonstrate, via X-ray photoelectron spectroscopy (XPS) analysis, that the binding energies

Phosphorescence-based O2 sensing reveals size-dependent survival and motility of metastatic prostate cancer cells in self-generated hypoxia

Cancer cells in solid tumors experience hypoxia, a condition of low O2 concentration, since their O2 demand exceeds the supply from the surrounding vasculature. However, how these cells adapt to hypoxia requires further elucidation. Here, we use a transparent phosphorescent thin film to visualize the self-generated hypoxia field of prostate cancer cells and quantify local O2 consumption rates, mea

Post Hoc Intervention as a Remedy for Gender Bias in Grant Application Reviews

The Swedish Research Council is a Swedish government agency and one of the major research financiers in Sweden. As such, its operations are governed by legislation and governmental instructions and policies, which prohibit discrimination and include equal treatment. Consequently, the Swedish Research Council has for a large number of years been working actively against gender bias in their reviews

Impact of the risk-adapted Nordic anal cancer group consensus guidelines on the contouring of the elective clinical target volume in anal cancer

Background and purpose: The recently published Nordic anal cancer group (NOAC) contouring guidelines aim for improved oncological outcomes and reduced toxicity in anal cancer patients treated with radiotherapy. The present work describes how the elective clinical target volume (CTVe) would change when applying the NOAC guidelines instead of the previous Australasian standard. According to the Aust

Is the business of conquest the conquest of business?

This case explores the interplay between commerce and colonial expansion through the lens of the Dutch East India Company (VOC) in the 17th century. Tasked with securing profit while navigating geopolitical rivalries, the VOC’s decision-makers faced dilemmas that blurred the lines between trade and conquest. This case places students in the role of the Heeren XVII, the governing board of the VOC,
