En el presente trabajo, se realiza un estudio numérico de mecánica de fluidos 2D en una contracción brusca para fluidos no newtonianos tipo ley de potencia de Ostwald-de-Waele. Se emplean dos métodos de resolución, ...

One of the main issues is the discrepancy between the measured and actual oil volumes of used cooking oil (UCO). Using a measurement tank as the measuring medium and an ultrasonic sensor as the tool, a system was develop...

Pio XI glacier, with an area of 1263 km 2 and a length of 65.7 km, is the largest of the Southern Patagonia Icefield (SPD. During the period 1945-1995 it experienced a net advance of ca. 10 km., a unique behavior conside...

Abstract Heart failure (HF) is a common disease resulting in high morbidity, mortality, and healthcare costs. An important cause of HF is mitral valve regurgitation (MR), which induces left ventricular remodeling and vol...

Background and purposeRadiotherapy (RT) often causes delayed radiation-induced brain injury (RBI) with unclear pathophysiology; emerging evidence links this to glymphatic dysfunction, but radiation effects on cerebrospin...

Background Ongoing debates question the harm of internet use with the evolving technology, as many individuals transition from regular to problematic internet use (PIU). The habenula (Hb), located between the thalamus an...

Abstract Background There is currently a lack of reference intervals (RIs) for the novel measures like 3‐dimensional (3D) echocardiography or speckle‐tracking strain for assessment of right ventricular (RV) structure...

Dental glass fiber is one of dental synthetic fibers that are widely used in dentistry as a dental resin reinforcement, such as in dentin replacement material. The availability of glass fiber is limited in Indonesia beca...

Abstract Objective New Zealand White (NZW) rabbits are widely used in interventional radiology research due to their suitability for human-sized treatment and imaging equipment, offering high translational potential. Thi...

Free-breathing spine-based positioning/tracking in lung stereotactic body radiotherapy is required when direct tumor positioning is not possible. Respiratory baseline, motion and target position reproducibility interact ...

Hypertension (HT) is very common in hemodialysis (HD) patients, and this is the most important factor that increase cardiovascular morbidity and mortality. In this study, we determimined theprevalance ofHT ( 2140/90 mmHg...

ABSTRACT Due to the conditions in which traditional sheep production systems operate, the evaluation of animal growth from live weight (LW) is limited by the high cost of the livestock scale as well as the sophisticated ...

BackgroundRobot-assisted simple prostatectomy (RASP) and laser enucleation of the prostate (LEP) are established surgical options for the treatment of large-volume benign prostatic hyperplasia (BPH); however, consensus r...

Background: Laparoscopic cholecystectomy, though less invasive than open surgery, still causes notable post-operative pain from port site trauma and abdominal distension. Regional techniques such as transverse abdominis ...

El objetivo de esta revisión fue evaluar la utilidad clínica del volumen plaquetario medio (VPM) como biomarcador accesible y económico para el pronóstico en pacientes con neoplasias sólidas y hematológicas. Se rea...

Panoramic radiography is a radiography technique which is commonly used in dentistry. X-ray radiation from panoramic radiography can cause biological damage, such as the increase of gingival crevicular fluid (GCF) volume...

Abstract Background Despite the favorable toxicity profiles of whole breast radiotherapy, there are subgroups that tend to experience high toxicity. This study examines anatomical and physiological characteristics that c...

Background/Aim: This study aimed to evaluate the masseter muscle volume and maximum bite force in individuals with different types skeletal malocclusion. The researchers conducted a comparative analysis to assess the rel...

Abstract Purpose This study aims to introduce an effective protocol for transvaginal ethanol sclerotherapy, focussing on the aspiration of viscous cystic content and the amount of ethanol instilled in the cystic cavity a...

Traditional bibliometric indicators such as the h-index emphasize cumulative citation impact but provide limited insight into the efficiency and concentration of that impact across a researcher's publication portfolio. T...

ABSTRACT Background Determining right ventricular (RV) volume typically requires three‐dimensional imaging due to its complex shape. The ellipsoid model offers a two‐dimensional alternative, employing area‐ or line...

Among the most prevalent yet poorly understood female health issues is uterine leiomyomas. In order to preserve fertility and avoid or delay surgical intervention, medical treatments are typically considered first-line. ...

Abstract Background Brain tumor therapeutic responses can be quantified from magnetic resonance images (MRI) using 1‐ (1D) and 2‐dimensional (2D) linear and volumetric methods, but few studies in dogs compare these t...
