Proteins interact through their interfaces, and dysfunction of protein-protein interactions (PPIs) has been associated with various diseases. Therefore, investigating the properties of the drug-modulated PPIs and interface-targeting drugs is critical. Here, we present a curated large data set for drug-like molecules in protein interfaces.

Background: The anticoagulation and risk factors in atrial fibrillation (ATRIA) score is associated with adverse cardiovascular events. However, its relationship with coronary thrombus burden is unclear. Therefore, we aimed to investigate the relationship between the ATRIA score and thrombus burden in patients with ST-segment elevation myocardial infarction (STEMI) who underwent percutaneous coronary intervention (PCI).

Water resource recovery facilities (WRRFs) performing biological nitrogen removal (BNR) often require external carbon sources for meeting nitrogen discharge permit limits. This brings an additional financial burden to the facilities considering the continuous need of these external carbon sources. This paper evaluates the utilization of airport stormwater, which in the winter season is rich in aircraft deicing fluid (ADF) as an alternative external carbon source.

Objective: This trial aims to assess the acceptability, feasibility, and safety of BioVirtualPed, a biofeedback-based virtual reality (VR) game designed to reduce pain, anxiety, and fear in children undergoing medical procedures.

Methods: An Oculus Quest 2 headset was used in the VR experience, respiratory data was captured using an ADXL354 accelerometer, and these data were integrated into the game with ArdunioUno software. The sample of this study consisted of 15 pediatric oncology patients aged 6 to 12 years between July and August 2023.

We focus on drug repurposing in the Ras signaling pathway, considering structural similarities of protein-protein interfaces. The interfaces formed by physically interacting proteins are found from PDB if available and via PRISM (PRotein Interaction by Structural Matching) otherwise. The structural coverage of these interactions has been increased from 21 to 92% using PRISM.

Structural and functional integrities of formulated proteins are key characteristics that provide a better understanding of influencing factors and their adjustment during formulation development. Here, the procedures commonly used for protein analysis were applied and optimized to obtain a higher degree of accuracy, reproducibility, and reliability for the analysis of lysozyme extracts from hot-melt extrudates (HME). The extrudates were prepared with polyethylene glycol 20 000.

Objectives: In this study, we evaluated and compared the level of myocardial ischaemia caused by cardiac syndrome X (CSX) and coronary slow flow (CSF) with single photon emission computed tomography myocardial perfusion imaging (SPECT-MPI), and determined if changes in the level of myocardial ischaemia exist in CSF and CSX cases according to thrombolysis in myocardial infarction frame count (TFC).

Materials And Methods: The study population consisted of 66 patients with CSF and 78 angiographically normal patients (36 of them with CSX and 42 of them healthy controls). The coronary flow rates of all patients were documented using TFC.

Purpose: Acromegaly is a rare disorder existed in the result of overproduction of growth hormone (GH). The disorder is associated with increased cardiovascular risk factors and metabolic abnormalities. Urotensin II (UII), a secreted vasoactive peptide hormone, belonging somatostatin superfamily, plays an essential role in atherosclerosis and glucose metabolism.

Background: The current study aimed at investigating the latent dimensional structure of sleep quality as indexed by the seven components of the Pittsburgh Sleep Quality Index (PSQI), as well as latent covariance structure between sleep quality, circadian preferences and depressive symptoms.

Methods: Two hundred twenty-five patients with major depressive disorder (MDD), with an average age of 29.92 ± 10.

Aims: Left bundle branch block (LBBB) causes a dyssynchronized contraction of left ventricle. This is a kind of regional wall-motion abnormality and measuring left ventricular ejection fraction (LVEF) by two-dimensional (2D) echocardiography could be less reliable in this particular condition. Our aim was to evaluate the role of dyssynchrony index (SDI), measured by three-dimensional (3D) echocardiography, in assessment of LVEF and left ventricular volumes accurately in patients with LBBB.

Background: This study evaluated whether subclinical myocardial dysfunction occurs in first-degree relatives of patients with idiopathic dilated cardiomyopathy (IDCM), using strain echocardiographic imaging, before apparent left ventricular (LV) failure is observed.

Patients And Methods: The study comprised 77 subjects aged 16-63 years who had first-degree relatives with a previous or new diagnosis of IDCM. LV myocardial deformation parameters of the first-degree relatives with normal LVEF (≥55%) values, as assessed using 2D echocardiography, were evaluated.

Objective: Atrial functions are relatively suppressed in heart failure (HF). We aimed to investigate the associations of intra- and inter-atrial electromechanical conduction delay (EMCD) with functional class and mortality over a 12-month follow-up period.

Methods: The prospective study included 65 patients with systolic HF and 65 healthy subjects with normal sinus rhythm.

In patients with left ventricular assist device (LVAD) implants, pump thrombosis is a potential life-threatening complication. In a retrospective data analysis, we compared clinical outcomes in 50 patients with HeartWare (HW) or HeartMate II implants undergoing device exchange (DEx; n = 21) or systemic thrombolysis (STL; n = 29) for pump thrombosis. Primary end-point was survival up to 90 days postintervention.

Objectives: In end-stage heart failure patients with left-ventricular assist device implantation and tricuspid valve (TV) regurgitation grade >2, the surgical strategy for TV regurgitation is unclear at present. We aimed to compare clinical outcomes in patients receiving left-ventricular assist device (LVAD) implants with or without TV repair (TVR).

Methods: We included 58 patients with TV regurgitation grade >2 in our data analysis.

Objective: The level of right ventricular (RV) systolic function has prognostic importance in right ventricular ST-segment elevation myocardial infarction (RV-STEMI). This study aimed to evaluate the changes in RV systolic function in patients with RV-STEMI according to the revascularisation method used for their management.

Methods: The first group consisted of 132 patients who received primary percutaneous coronary intervention (PPCI).

In rats, hormonal fluctuations during the estrus cycle may have numerous behavioral and neurobiological consequences. The aim of this study was to investigate the effects of estrus cycles and citalopram on behavior, ultrasonic vocalizations, anxiety levels, and c-fos expression in rats. With this aim, the rats were grouped into two: (1) a control group (n=16) and (2) a citalopram group (n=16), which received daily intraperitoneal 20mg/kg citalopram from baseline (D0) to the 10th day (D10).

We present a 52-year-old man with swelling, tightness, heaviness, and redness in the right half of his neck, face, upper arm, and right precordial area after repetitive exercises. No etiological factors such as trauma, venous catheter, malignancy, hematologic disorder history, or any chronic disease were noted. A Doppler ultrasound of the upper extremities was performed, which showed a complete thrombotic occlusion in the right internal jugular vein, partial occlusion in the right brachiocephalic and subclavian veins with thrombosis, and chronic thrombosis occluding the left brachial vein.
