In this study, a high-speed, fast responsive, non-intrusive ultrasonic thermometry system was proposed as a potential candidate for overcoming the disadvantages of thermocouples. The principle of this system is based on the thermal dependence of the speed of sound, and the temperature is measured by detecting the flight time of ultrasonic wave (USW) between the transmitter and the receiver. For a

BACKGROUND: The optimal management of a torn anterior cruciate ligament (ACL) of the knee is unknown. METHODS: We conducted a randomized, controlled trial involving 121 young, active adults with acute ACL injury in which we compared two strategies: structured rehabilitation plus early ACL reconstruction and structured rehabilitation with the option of later ACL reconstruction if needed. The primar

Viral vector-mediated gene transfer utilizing adeno-associated viral vectors has recently entered clinical testing as a novel tool for delivery of therapeutic agents to the brain. Clinical trials in Parkinson's disease using adeno-associated viral vector-based gene therapy have shown the safety of the approach. Further efforts in this area will show if gene-based approaches can rival the therapeut

Diagnosis of primary hepatocellular carcinoma (HCC) at early stages has obviously been improved since determination of serum levels of free alpha-fetoprotein (AFP) was implemented. AFP has been considered as the standard tumor marker of primary HCC, although certain patients have very low serum free AFP levels. In the present study, clinical application of measuring serum AFP-IgM immune complexes

Summary Background: Real-time perfusion (RTP) adenosine stress echocardiography (ASE) can be used to visually evaluate myocardial ischaemia. The RTP power modulation technique, provides images for off-line parametric perfusion quantification using Qontrast((R)) software. From replenishment curves, this generates parametric images of peak signal intensity (A), myocardial blood flow velocity (beta)

Kai Söderhjelm (b. 1918 in Helsinki, d. 1996 in Gothenburg) belonged to a Finland-Swedish cultural family, and was for many years an important and valuable figure in the intellectual life of Sweden. Söderhjelm’s authorship follows the same clear thematic lines from his first book, Rid mot nordväst (1948; Ride to the northwest), to his last, Okänt land (1993; Unknown land). These themes are peace,

Popular Abstract in Swedish Denne populationstudie om kataraktkirurgi strakte sig over en pre- og peroperativ fase med indsamling af data i perioden 1986-1990. Den postoperative dataindsamling i denne redegørelse dækker perioden 1986-1992. Epidemiologiske forhold belyses i det første og syvende arbejde. Anatomiske og især refraktive forhold bliver belyst i den andet og tredje publikation. Det fjerThere has been a striking increase in the number of cataract operations in the referral region of the Lund Health Care District during 1986 through 1990, in 1990 reaching 3.6 per 1000 inhabitants. Different preoperative, intraoperative and postoperative variables and observations were registered and analysed for 5878 consecutive cataract cases operated in the period studied. Women predominate in t

Compared to animals like ourselves, plants have a very flexible sexual life. Most plants are, for example, hermaphrodites with the potential capacity for reproduction by self-fertilization (or selfing). While selfing can provide several definite advantages for the individual plant, there is a downside; mainly the severe reduction in fitness due to inbreeding depression. To avoid the negative conse

The concentrations of gas-phase potassium hydroxide (KOH), potassium chloride (KCl) and atomic potassium (K(g)) were quantitatively measured from the near-surface to downstream area of burning pinewood pellets by a newly developed photofragmentation tunable diode laser absorption spectroscopy (PF-TDLAS) technique to reveal the original form of the released potassium. The novel arrangement of the P

INTRODUCTION: The Alzheimer's Association Global Biomarker Standardization Consortium conducted a blinded case–control study to learn which phosphorylated tau (p-tau) assays provide the largest fold-changes in Alzheimer's disease (AD) versus non-AD and show commutability in measuring patient samples and candidate certified reference materials (CRMs). METHODS: Thirty-three different p-tau assays me

Objectives: Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) libraries have limited capabilities for identification of Streptococcus bovis/Streptococcus equinus-complex (SBSEC) subspecies. The objective was to develop and validate novel MALDI-TOF MS libraries adapted to diagnostic culturing and sampling conditions for improved identification of SBSEC subs

Tool-based code review has been an established software engineering practice for at least a decade. However, while software development environments have improved significantly during this time with advanced features for code comprehension, refactoring, and AI support, code review tools have remained more static and are still centered around a two-way textual diff view with features similar to whe

BACKGROUND: Extensive head and neck reconstructive surgery is a complex procedure often performed in patients with multiple comorbidities, and the risk of complications is high. Evidence-based preoperative assessment and reliable risk prediction are therefore essential, and the anesthesiologist plays an important role in this process. The aim of this study was to evaluate the predictive properties

Background: In cardiovascular magnetic resonance, late gadolinium enhancement (LGE) is the standard method to visualize myocardial infarction (MI). Many algorithms quantifying infarct size in LGE images exist. However, only few algorithms have been validated, i.e., benchmarked against an ex-vivo measurement. Furthermore, the reported algorithm performance varies considerably between studies. Objec

While a naive algorithm for multiplying two 2 × 2 matrices requires eight multiplications and four additions, Strassen showed how to compute the same matrix product using seven multiplications and 18 additions. Winograd reduced the number of additions to 15, which was assumed to be optimal. However, by introducing a change of basis, Karstadt and Schwartz showed how to lower the number of additions

Purpose: To characterise the baseline clinical features and genotypes of adults with pre-mRNA processing factor 31 (PRPF31)-associated retinal dystrophy (RD) enrolled in a prospective, multicentre 4-year natural history study, and to explore correlations between selected baseline parameters. Methods: Thirty-one patients with PRPF31-RD underwent comprehensive multimodal assessment, including slit-l

PurposeBlockchain technology (BCT) is a novel and disruptive innovation that can transform procurement processes in various industries, including the food sector. BCT can offer benefits such as transparency, traceability, security, and efficiency for procuring food products, which are essential for ensuring food security and quality. However, BCT faces several challenges that hinder its adoption a

Galactoglucomannan (GGM) has been identified as a valuable resource and can be used in fields such as oxygen barrier films, food coatings or hydrogels. This hemicellulose can be extracted from softwood using steam explosion (STEX) under mild conditions. However, the GGM-solution also contains impurities such as lignin, lignin-carbohydrate complexes, organic acids, and salts, which require further
