Aim: Aspiration of the abscess cavity versus excision of capsule are still in debate for the capsulated, large, superficially located abscesses. Material and Methods: Twenty patients who had large, solitary, capsulated, and superficially located lobar abscesses were analyzed retrospectively to compare the efficiency of two different surgical approaches and their impact on postoperative antibiotic

Soft tissue response to the presence of polypropylene-g-poly(ethylene glycol) comb-type graft copolymers containing gold nanoparticles

The aim of this study is to evaluate the soft tissue response of the pure and Au-embedded PPg-PEG. PP-g-PEG2000, PP-g-PEG4000, Au-PP-g-PEG2000, and AuPP-g-PEG4000 were obtained via chlorination of polypropylene and polyethylene glycol in the presence of a base with a "grafting onto" technique. Solvent cast films of these four copolymers with PP as a control group were embedded into five different

Ataxic gait due to giant cystic virchow-robin spaces : Case report

Virchow-Robin spaces (VRSs) are perivascular pia-lined extensions of the subarachnoid space around the arteries and veins as they enter the brain parenchyma. The precise etiology of these enlarged perivascular spaces (PVSs) is unknown. VRSs usually do not cause significant mass effect and neurologic deterioration. However; cystic enlargement of giant VR spaces may be misinterpreted in radiological

Synthesis of microbial elastomers based on soybean oily acids. Biocompatibility studies

Biocompatibility studies of the autoxidized and unoxidized unsaturated medium-long chain length (m-lcl) co-poly-3-hydroxyalkanoates (m-lclPHAs) derived from soya oily acids have been reported. Pseudomonas oleovorans was grown on a series of mixtures of octanoic acid (OA) and soya oily acids (Sy) with weight ratios of 20:80, 28:72 and 50:50 in order to obtain unsaturated m-lcl copolyesters coded PH

Isolated paralysis of glossopharyngeal and vagus nerve associated with type II occipital condyle fracture : Case report

Introduction: Occipital condyle fractures (OCFs) can occasionally be complicated with lower cranial nerve palsies. Discussion: Isolated 9th and 10th cranial nerve palsies following OCF are very rare. To our knowledge, we report the first case of an early onset of 9th and 10th cranial nerve palsies with an early full recovery in short period of time and discuss the probable mechanism of isolated ne

Ruptured aneurysm at the perforating artery supplying the insula : Case report

OBJECTIVE: Aneurysms originating from perforating branches of the middle cerebral artery are quite rare. Most of them arise from the lenticulostriate arteries, frequently located within the basal ganglia. We report a perforating artery aneurysm that was entirely embedded within the limen insulae. CLINICAL PRESENTATION: A 41-year-old man presented with an insular hematoma without subarachnoid hemor

Effects of pravastatin on cellular ultrastructure and hemorheology in rats after traumatic head injury

Pravastatin has neuroprotective effects against aging but its role in brain injury remains unclear. This study evaluated the effects of pravastatin on the ultrastructural changes and hemorheological parameters in rats after traumatic brain injury (TBI) of right parietal cortical contusion by a controlled weight-dropping method. There were three groups: (I) Sham operated group; (II) TBI + vehicle (

Remote carbon cycle changes are overlooked impacts of land cover and land management changes

Land cover and land management changes (LCLMCs) have a substantial impact on the global carbon budget and, consequently, on global climate via the biogeochemical (BGC) effects. The commonly considered BGC effects refer to the direct influence of LCLMCs on local carbon stocks (local BGC effects). However, LCLMCs also influence climate by altering the local surface energy balance due to changes in l

The Influence of Heterogeneity and Confining Pressure on the Hydromechanics of a Sandstone Using Neutron and X-Ray Imaging

This study utilizes advanced 3D imaging techniques, combining X-ray and neutron tomography, to investigate the hydromechanical evolution of Idaho Gray sandstone during coupled triaxial permeability tests. The analysis involved correlating mechanical and hydraulic bulk measurements, porosity fields, strain fields derived from Digital Volume Correlation analysis and fluid speed fields derived from t

Nature connectedness and other transformative qualities associated with pro-environmental attitudes, behaviors, and engagement across scales : the direction of compassion matters

Current policy approaches addressing climate change have been insufficient. Integrative approaches linking inner and outer factors of behavior change, both at the private and organizational level, have been called for. The aim of the present study was thus to conceptualize and test a model of interlinkages between trainable transformative psychological qualities, meditation practice, wellbeing, st

Biomarkers associated with worsening renal function and progression in chronic kidney disease among patients hospitalized for acute heart failure

INTRODUCTION: Worsening renal function (WRF) is associated with poor prognosis in patients with heart failure (HF). Osteopontin (OPN) and Matrix extracellular phosphoglycoprotein (MEPE) are expressed in the kidneys and are involved in bone mineralization processes. Higher OPN levels have been associated with a higher risk for adverse outcomes in patients with chronic kidney disease (CKD), and MEPE

Electron and X-ray Beam Control in Laser Wakefield Acceleration

This thesis focuses on the optimization and control of laser-driven plasma-based acceleration, whichinvolves the driver laser pulse, the accelerated electrons and the subsequent generation of x-rays.In laser wakefield acceleration (LWFA), a high-power laser pulse, typically with terawatt-levelpower, is focused tightly into a gas, reaching intensities on the order of > 1018 W/cm2. Even at the leadi

Mobilizing Knowledge : Framing Gender-based Violence and Negotiating Social Protection for Migrant Women with Precarious Legal Status

Idag lever allt fler människor under förhållanden som definieras som prekära. Även i avancerade välfärdssamhällen lyckas inte de traditionella trygghetssystemen erkänna och hantera de nya sociala risker som dessa grupper inom ”prekariatet” ställs inför. Bland dessa grupper finner vi migrantkvinnor med osäker rättslig ställning. Denna forskning undersöker hur aktörer i akademin och i civilsamhälletIn advanced welfare societies, traditional welfare programs are failing to recognize and respond to new social risks faced by groups in precarious life situations, including migrant women. This research explore how actors in academic and civil society settings recognize and frame the struggles of migrant women with precarious legal status, particularly in terms of gender-based violence (GBV) and a

Exploring the Influence of Parental Mental Illness on Childhood Cancer Mortality : A Nationwide Cohort Study in Sweden

Background: Parents face mental health challenges following their child's cancer diagnosis. However, it is unknown whether parental mental illness following a childhood cancer diagnosis influences the child's mortality.Patients and methods: Using several nationwide registers in Sweden, we identified children diagnosed with cancer between ages 0 to 14 from 2005 to 2016. Parental mental illness was

The Wolf Shall Dwell with the Lamb : permanent installation, Tel Aviv Jaffa

The sculpture, The Wolf Shall Dwell with the Lamb, is a contemporary adaptation of the prophecy of Isaiah (Chapter 11, Verse 6), installed as a suspended monument to world peace. At first glance, the figures of the wolf and lamb rest together, enveloped in cloth, as if frozen in a moment just before the public unveiling of the sculpture. Yet upon closer inspection, the fabric is revealed as insepa

From the Masthead to the Map : An Experimental and Digital Approach to Viking Age Seafaring Itineraries

The Viking Age (c. 800–c. 1050 ad) was characterised by a widespread rise in maritime mobility and interaction, as is made clear by an increasing range of evidence. However, this evidence provides limited information about the sailors and the sailing voyages that connected and transformed the Viking world. This paper presents an approach to reconstruct Viking Age maritime itineraries through the c

Tattoos and cutaneous squamous cell carcinoma : a population-based case-control study

The prevalence of tattoos in western countries is about 20%. Tattoo ink may contain carcinogenic compounds. The aim of this study was to investigate if tattoo exposure is associated with an increased risk of cutaneous squamous cell carcinoma in individuals. In this population-based case-control study, 2857 cases aged 20 to 60 years, diagnosed between 2014 and 2017, were identified in the Swedish C
