Background: Immune checkpoint inhibitors (ICI) are generally associated with rare cardiac side effects, yet instances like myocarditis can be fatal. Therefore, detecting and managing left ventricular dysfunction early in ICI therapy is vital.

Objectives: This study aims to evaluate whether left ventricular global longitudinal strain (LV GLS) is a predictor for early detection of cardiac dysfunction in patients receving ICI.

Background: Synthesis of organic@inorganic hNFs is achieved by the coordination of organic compounds containing amine, amide, and diol groups with bivalent metals. The use of bio-extracts containing these functional groups instead of expensive organic inputs such as DNA, enzymes, and protein creates advantages in terms of cost and applicability. In this study, the application potentials (antioxidant, antibacterial, anticancer, guaiacol, anionic, and cationic dye degradation) of hybrid (organic@inorganic) nanoflowers (hNFs) synthesized with Cu and snakeskin (SSS) were proposed.

Background: While much of the world's attention is focused on the effects of SARS-CoV-2 on physical health, the virus's psychological impacts must not be disregarded. Therefore, it is important to understand and document the role of emotional intelligence as a mitigating variable in the relationship between psychological distress and life satisfaction.

Subjects And Methods: This correlational study was carried out with the participation of 483 college students.

Article Synopsis
  • Curcumin was combined with Cu (II) ions to create a new hybrid nanostructure (Cu-hNs), marking a first in this research.
  • The study investigated the Cu-hNs' catalytic effects on guaiacol and their antimicrobial properties against fish pathogen bacteria, noting their strong activity.
  • Characterization techniques like SEM, EDX, and FT-IR were employed, revealing that curcumin's lack of reactive groups limited the uniformity of Cu-hNs, while solution pH influenced their formation.

Objective: Although organic-inorganic hybrid nanoflowers (hNFs) with much enhanced catalytic activity and stability were fabricated using proteins and enzymes, in this study, for the first time, we report synthesis of allicin and copper ion (Cu) coordinated NFs and investigate their peroxidase-like and antimicrobial activities.

Results: The allicin (active ingredient of Allium sativum) and Cu was acted as an organic and inorganic part, respectively for synthesis of the Cu-hNFs. The hNFs were characterized by various techniques.

Facial soft tissue thicknesses (FSTT) measurements collected from Magnetic Resonance Imaging (MRI) and Computed Tomography (CT) imaging techniques are most commonly taken in the supine position for forensic craniofacial reconstruction. FSTT have been shown to be different in comparison to the upright position due to gravity. The variation of facial morphology between the upright and supine position of laser-scanned images taken from 44 individuals was investigated using volumetric analysis with deviation maps.

The aim of this study was to investigate seasonal heavy metal accumulation and translocation characteristics of the narrow-leaved cattail (Typha angustifolia L.). Sediment and plant samples were taken seasonally from six different locations identified for this purpose, and Pb, Cr, Cu, Ni, Zn, and Cd concentrations as well as accumulation factor (AF) and translocation factor (TF) values were determined.

Objectives: It has been proposed that human platelet antigen-1 (HPA-1) gene polymorphism is associated with coronary artery disease (CAD) and affects platelet function. We aimed to investigate the distribution of HPA gene polymorphism between angiographic CAD and a control group and the relation between HPA gene polymorphism and platelet aggregation.

Study Design: The study population consisted of 94 patients with angiographic CAD and 115 patients without angiographic CAD.

Objective: Neutrophil gelatinase-associated lipocalin (NGAL) is a novel marker for early detection of renotubular deterioration. Despite the limited data concerning the NGAL in heart failure (HF), significance of NGAL in right-sided HF remains unknown. We assessed serum and urinary NGAL in left and right-sided HF due to non-ischemic cardiomyopathy (NICMP) and severe pulmonary arterial hypertension (PAH).

Acute renal infarction due to emboli represents a very rare but significant threat for kidney loss, and the clinical presentation is challenging. The differential diagnosis of massive renal thrombi includes all other causes of abdominal pain, and they can be easily misdiagnosed as renal colic due to nephrolithiasis. Although there are a few case reports regarding the possibility that cardiac emboli may cause acute kidney infarction, intracardiac thrombi within the ventricular cavity diagnosed by echocardiography as a cause of such renal artery occlusion have never been reported in patients with cardiomyopathy.

The mainstay of treatment for massive pulmonary embolism in nonpregnant individuals is urgent thrombolytic therapy, but experience with these drugs in pregnancy is limited. We report a case of a 36-year-old woman at 27 weeks' gestation who was admitted with a massive, life-threatening pulmonary embolism. The diagnosis was rapidly accomplished in the coronary care unit by transthoracic echocardiography that showed signs of pulmonary hypertension as well as a large, free-floating thrombus in the right heart.

Background: Pulmonary arterial hypertension (PAH) is a chronic progressive disease characterized by persistent elevation of pulmonary artery pressure. Regardless of the initial trigger, the elevated pulmonary arterial pressure and vascular resistance in patients with PAH are primarily caused by remodeling and thrombosis of small- and medium-sized pulmonary arteries and arterioles, as well as sustained vasoconstriction. Recent studies have emphasized the relevance of several biomarkers of hemostasis in the PAH progression.
