Cigarette smoking and perceived risk of cardiovascular disease in Iran.

Introduction: Studies have consistently demonstrated a strong link between cigarette smoking and an increased risk of cardiovascular diseases (CVD). On the other hand, studies have shown that most smokers do not have a real understanding of the cardiovascular health hazards of smoking. Therefore, the study aimed to determine the perceived risk of Myocardial Infarction (MI), Hypertension (HTN), and Stroke among current smokers in Iran.

Nanotechnology and LSTM machine learning algorithms in advanced fuel spray dynamics in CI engines with different bowl geometries.

This study explores the integration of nanotechnology and Long Short-Term Memory (LSTM) machine learning algorithms to enhance the understanding and optimization of fuel spray dynamics in compression ignition (CI) engines with varying bowl geometries.

Simultaneously, LSTM models are employed to analyze and predict the complex spray behavior under diverse operational and geometric conditions.

Animal origins free products in cell culture media: a new frontier.

Despite the importance of finding replacements for fetal bovine serum (FBS), very few studies have focused on this subject. Historically, the use of animals and their derivatives in growth, reproduction, and physiological studies has raised several concerns. The supplementation of culture media with FBS, also known as fetal calf serum, continues to be widespread, despite its limitations in quality, reproducibility, and implications for animal welfare.

Triaxial compression and shear strength characteristics of two-stage concrete: an experimental study.

The research necessity stems from the need to understand and evaluate the performance of Two-Stage Concrete (TSC) under triaxial compression conditions, as prior studies have predominantly focused on uniaxial and biaxial testing of conventional concrete (CC). This study represents the first comprehensive investigation into the triaxial compressive strength and related mechanical properties of TSC, addressing a critical gap in the existing body of literature. Three different mixtures were prepared, including one CC and two TSC variants with varying cement content.

Linear Inverse Sandwich Complexes of Tetraanionic Benzene Stabilized by Covalent δ-Bonding with Late Lanthanides.

A series of dilanthanide benzene inverse sandwich complexes of the type (CpLn)(μ-η:η-CH) () (Ln = Y, Gd, Tb, Dy, Tm) are reported. These compounds are synthesized by reduction of the respective trivalent dimers CpLnI (Ln = Y, Gd, Tb, Dy, Tm) in diethyl ether with potassium graphite in the presence of benzene, and they feature an unusual linear coordination geometry with a highly planar benzene bridge as verified by single-crystal X-ray diffraction. The Ln-Bz distances of are the shortest distances observed to date, ranging from 1.

Unrealistic risk perceptions of Iranian current cigarette smokers on developing lung cancer and chronic obstructive pulmonary disease (COPD): a cross-sectional study.

Cigarette smoking causes serious complications and diseases in a person's life, such as Chronic Obstructive Pulmonary Disease (COPD) and some cancers, including lung cancer. On the other hand, studies have shown that smokers do not have a real understanding of the health hazards of smoking. This study was conducted to determine the perceived risk of lung cancer and COPD in current smokers.

Dinitrogen reduction chemistry with scandium provides a complex with two side-on (N[double bond, length as m-dash]N) ligands bound to one metal: (CMe)Sc[(µ-η:η-N)Sc(CMe)].

Although there are few reduced dinitrogen complexes of scandium, this metal has revealed a new structural type in reductive dinitrogen chemistry by reduction of bis(pentamethylcyclopentadienyl) scandium halides under N. Reduction of (Cp* = CMe) with potassium graphite (KC) under dinitrogen generates the dark blue paramagnetic complex , 1. This end-on bridging (N[double bond, length as m-dash]N) complex is a diradical with a magnetic moment of 2.

Production of Cartilaginous Organoids: Potential Opportunities and Challenges, A Review Article.

Damaged articular cartilage has limited self-healing potential and often leads to osteoarthritis (OA), pain, and dysfunction of the affected joint. Autologous and allogenic transplants cannot fully meet the needs of clinical treatment. Two dimensional (2D) and three-dimensional (3D) cell cultures can help to study growth modeling and physiological characteristics of the human body.

NEAT1 and CHROMR lncRNAs: a promising diagnostic tool for diffuse large B-cell lymphoma especially in elderly patients.

Long non-coding (lnc) RNAs have crucial regulatory roles in molecular pathways, and their dysregulation is associated with the pathogenesis of malignancies such as Diffuse large B-cell lymphoma (DLBCL). Therefore, we aimed to study the NEAT1 and CHROMR expression in DLBCL and explore their association with clinicopathological characteristics. DLBCL and non-tumor lymph node specimens were obtained to assess the expression levels.

The Scandium(II) Carbonyl Complex (CHBu)Sc(CO) and Its Isocyanide Analog (CHBu)Sc(CNCHMe-2,6).

Treatment of the scandium(II) metallocene CpSc (Cp = CHBu) with CO or the isocyanide CNXyl (Xyl = CHMe-2,6) yields the carbonyl complex CpSc(CO), , or the isocyanide complex CpSc(CNXyl), , which were identified by X-ray crystallography. Isotopic labeling with CO shows the CO stretch of at 1875 cm shifts to 1838 cm in . The CN stretch in is shifted to 1939 cm compared to 2118 cm for the free isocyanide.

Accuracy of special histochemical staining methods in diagnosis of oral pathology: A systematic review and meta-analysis.

Clinical decision-making and biomedical research heavily rely on imaging techniques to visualize tissue morphology. To examine tissues in detail, it is necessary to use special histochemical stains to enhance contrast. This meta-analysis aimed to assess the sensitivity and specificity of these stains in diagnosing oral pathologic specimens.

Evaluating the role of amino acids and isothermal dry particle coating in modulating buccal permeation of large molecule drug vancomycin.

The formulation and delivery of macromolecules through the oral route pose considerable challenges due to factors such as large molecular weight, pH sensitivity, and limited formulation approaches. This challenge is compounded if the drug is poorly permeable, necessitating innovative drug delivery strategies. Vancomycin, a widely prescribed glycopeptide antibiotic, has an oral bioavailability of less than 10%, leading to predominantly intravenous administration and potential patient discomfort.
