Composition-dependent spin exchange interaction for multiferroicity in perovskite Pb(Fe1/2Nb1/2)O3

The composition-dependent spin exchange interaction in a perovskite-structured Pb(Fe0.5−xNix)Nb1/2O3 system has been studied to understand its multiferroicity at room-temperature. Special emphasis was paid to the magnetic behavior in terms of magnetic moment, interatomic distance, and atomic ordering because they play a key role in the modulation of magnetic multiferroic behavior. We observed that

Extracellular vesicles released from microglia after palmitate exposure impact brain function

Dietary patterns that include an excess of foods rich in saturated fat are associated with brain dysfunction. Although microgliosis has been proposed to play a key role in the development of brain dysfunction in diet-induced obesity (DIO), neuroinflammation with cytokine over-expression is not always observed. Thus, mechanisms by which microglia contribute to brain impairment in DIO are uncertain.

Experimental and kinetic modeling study of the laminar burning velocity of CH4/H2 mixtures under oxy-fuel conditions

The oxy-fuel combustion of coke oven gas generates CH4/H2/O2/CO2 mixtures, and this study focuses on measuring the laminar burning velocities of these mixtures which are rarely studied previously. The investigation encompasses a range of equivalence ratios from 0.6 to 1.5, O2/(O2 + CO2) ratios varying between 0.25 and 0.38, and H2/(H2 + CH4) ratios ranging from 0.25 to 0.6, under normal temperatur

Serum levels of biomarkers related to severity staging of Raynaud’s phenomenon, neurosensory manifestations, and vibration exposure in patients with hand-arm vibration injury

Our aim was to explore possible relationships between serum levels of biomarkers in patients with hand-arm vibration injury in relation to the severity of the vascular, i.e., Raynaud’s phenomenon (RP), and neurosensory manifestations, the current exposure level, and the duration of exposure. This study was of case series design and involved 92 patients diagnosed with hand-arm vibration injury. Jon

An explainable machine learning model to solid adnexal masses diagnosis based on clinical data and qualitative ultrasound indicators

Background: Accurate characterization of newly diagnosed a solid adnexal lesion is a key step in defining the most appropriate therapeutic approach. Despite guidance from the International Ovarian Tumor Analyzes Panel, the evaluation of these lesions can be challenging. Recent studies have demonstrated how machine learning techniques can be applied to clinical data to solve this diagnostic problem

Neural semantic effects of tone accents

This study investigated whether the brain utilizes morphologically induced tones for semantic processing during online speech perception. An auditory comprehension task was conducted while measuring event-related potentials (ERPs). The study tested whether a discrepancy between contextual expectations and the tonal realizations of the target word would yield an N400 effect, indicative of semantic

Forests don’t just absorb CO2 — they also take up methane

Field studies reveal that the woody surfaces of upland trees are a substantial global sink for methane, a potent greenhouse gas. The findings help to fill a hole in the global methane budget and should improve the accuracy of climate models.

The prognostic value of programmed death-ligand 1 (PD-L1) expression in resected colorectal cancer without neoadjuvant therapy - differences between antibody clones and cell types

BACKGROUND: Programmed death-ligand 1 (PD-L1) expression on tumor cells is associated with poor prognosis in several malignancies, while partly contradictory and inconclusive results have been presented for colorectal cancer (CRC). This study aimed to evaluate PD-L1 as a prognostic biomarker in CRC by comparing three different antibody clones.METHODS: Patients surgically treated for CRC between Ja

Mortality and morbidity among heart transplant recipients in Sweden. Limitations of a life with a transplanted heart.

Bakgrund För noggrant utvalda patienter med avancerad hjärtsvikt är hjärttransplantation den optimala behandlingen för att förbättra överlevnad och livskvalitet. Men trots detta är sjukligheten fortfarande betydande inom gruppen. Med avhandlingen ville vi undersöka utfallet bland hjärttransplanterade patienter i Sverige med fokus på dödlighet, samsjuklighet och fysiska begränsningar som är relater

Sanktioner på affärsrättens område : Skadestånd, sanktionsavgifter, viten m.m.

Affärsrättsligt Centrum vid Lunds universitet (ACLU) bedriver forsknings- och seminarieverksamhet på centrala förmögenhetsrättsliga områden. En viktig del av den verksamhet som bedrivs inom ACLU är att regelbundet publicera böcker som består av originalbidrag från forskare och praktiker som har anknytning till ACLU. Målsättningen för ACLU:s publikationer är att de ska belysa aktuella och praktiskt

Ciita Regulates Local and Systemic Immune Responses in a Combined rAAV-α-synuclein and Preformed Fibril-Induced Rat Model for Parkinson’s Disease

Background: Parkinson's disease (PD) is characterized by alpha-synuclein (α-Syn) pathology, neurodegeneration and neuroinflammation. Human leukocyte antigen (HLA) variants associated with PD and α-Syn specific CD4+ T lymphocytes in PD patients highlight the importance of antigen presentation in PD etiology. The class II transactivator (CIITA) regulates major histocompatibility complex class II (MH
