Invertebrate embryos have relatively low fossilization potential; however, when preserved, they can offer crucial insights into the evolutionary developmental biology of extinct animals. Here we report new exceptionally preserved fossil embryos from the early Fortunian (early Cambrian) of China, which are assigned to two new taxa, Saccus xixiangensis gen. et sp. nov. and Saccus necopinus gen. et s

Få saker skrämmer människor så mycket som att förlora minne och identitet. Detta är dock en realitet för många som lever med demens. I bokens åttonde kapitel undersöker Glenn Möllergren de levnadsbe-rättelser som numera används inom äldreomsorgen för att kunna stödja individer och ge en god personcentrerad omsorg. I sin genom-gång visar Möllergren att det finns en stor variation i utformningen av

Hypothesis: Low-frequency Raman (LFR) spectroscopy is proposed as a novel non-destructive methodology to probe pH-related phase transitions in self-assembled lipid particles. In this case, dispersed lipid mesophases were composed of ionisable oleic acid (OA) or nicergoline (NG) in monoolein (MO). The sensitivity of LFR spectroscopy to low-energy intermolecular vibrations was hypothesised to be due

To solve the problem of fatigue of the UAV operator during long-term search and reconnaissance missions, a research hardware and software complex was created, in which the positioning of the auxiliary UAV video camera with a narrow field of view is carried out. Dynamixel Library for MATLAB and Simulink was used to organize the interaction of actuators with the virtual environment, which allows com

Purpose: Although total dietary protein intake has been associated with bladder cancer (BC) risk, the effect of the origin (plant or animal) and the substitutions remain to be understood. This study aimed to investigate the effect of total dietary protein, animal-based protein, plant-based protein, and their substitutions with each other on the risk of BC using a pooled analysis of 10 cohort studi

New antimicrobial and anti-inflammatory therapeutics are needed because of antibiotic resistance development and resulting complications such as inflammation, ultimately leading to septic shock. The antimicrobial effects of various nanoparticles (NPs) are currently attracting intensive research interest. Although various NPs display potent antimicrobial effects against strains resistant to convent

The accurate representation of mixed-phase monsoon clouds and their phase distribution is of great importance for numerical models used to predict monsoon rainfall. Therefore, it is essential for these models to correctly capture the phase fraction of clouds, which includes the proportions of liquid and ice. Ice particle formation in clouds occurs through primary ice production and secondary ice p

To increase the utilisation rate of the power system and accelerate electrification while providing a high degree of security and reliability, System Integrity Protection Schemes (SIPS) are of great importance. SIPS functions are automatic remedial actions, detecting abnormal conditions or contingencies in the system and taking control action to mitigate these conditions. Design, implementation, m

The aim of this thesis was to investigate the interactions between the kallikrein-kinin system (KKS) and the complement system during vascular inflammation and the contribution of extracellular vesicles (EVs). Vasculitis, in patients and in experimental models, was studied as a prototype inflammatory disease of the vasculature.Papers I and II addressed the impact KKS signalling has on complement a

2-amino-2-methyl-1-propanol (AMP) in dimethyl sulfoxide (DMSO) is a precipitating non-aqueous amine technology that can potentially lower the energy demand during CO2 removal from industrial flue gases compared to aqueous amine technologies. However, DMSO is hygroscopic and has a high possibility of absorbing water from humid flue gases, which can affect the physical properties of the system,

This study investigates city dynamics employing a nonextensive diffusion equation suited for addressing diffusion within a fractal medium, where the nonadditive parameter, q, plays a relevant role. The findings demonstrate the efficacy of this approach in determining the relation between the fractal dimension of the city, the allometric exponent and q, and elucidating the stationary phase of urban

Background: Levodopa–entacapone–carbidopa intestinal gel (LECIG) was introduced on the Swedish market in 2019. The therapy is aimed at patients with Parkinson's disease (PD) with fluctuations and dyskinesias. Long-term efficacy and safety data are lacking. Objective: To investigate the efficacy, tolerability, and safety of LECIG in regular clinical practice for Parkinson's disease in Sweden. Metho

Sound is a valuable cue in the marine environment that can inform animals about habitat location and community composition. Indeed, sound is often used for orientation and navigation by larval reef fishes during settlement. However, despite sound’s role in the early life of reef fishes, whether post-settlement reef fishes use ambient soundscapes to inform their movement decisions remains less clea

PURPOSE OF REVIEW: Small cell lung cancer (SCLC) is an aggressive disease with a poor prognosis, whereas its metastatic capacity carries a predilection for the brain. Although prophylactic cranial irradiation (PCI) has been used to address this problem, upcoming alternatives might necessitate reflection of its application in SCLC treatment. RECENT FINDINGS: The addition of immunotherapy to treatme

There are some evidences that hypogammaglobulinemia in newly diagnosed diffuse large B cell lymphoma (DLBCL) is a predictor for inferior outcome, but the risk for infection-related admissions specifically related to hypogammaglobulinemia is not known. The aim was to explore if hypogammaglobulinemia in untreated DLBCL in a Swedish cohort was associated with inferior outcome, and to assess the relat

The efficiency of ultrafiltration (UF) of acidified skim milk (SM) is impaired by protein aggregation and mineral scaling. The aim of this study is to assess the potential of acidification by electrodialysis with bipolar membranes (EDBM), in comparison with citric acid (CA), prior to the UF process on filtration performance, fouling and composition of the protein concentrates. Electro-acidificatio

The annexation of Crimea, the subsequent insurgency of Russian-backed separatists in the Donbas region of Ukraine in 2014 and the current full-scale Russian invasion of Ukraine have led to different responses from political elites, diasporas and migrants currently residing in different European countries. The historic decision of Sweden to send defence weapons to Ukraine as well as to apply for NA
