Background: This study investigates the impact of different harvesting techniques on the morphology and endothelial function of the left internal mammary artery (LIMA) grafts in coronary artery bypass grafting (CABG).
Methods: Fifty-three patients undergoing elective CABG were randomly assigned to two groups based on the harvesting technique: traditional clipping and nonclipping. Histological analyses revealed that arteries in the nonclipped group exhibited greater dilation and preserved endothelial integrity compared to the control group.
Background and objective It has been suggested that knee osteoarthritis (KOA) is associated with the development of calcification and an increased risk of cardiovascular (CV) disease, while the contribution of KOA grade is not clearly known enough. This study aimed to investigate the relationship between the grade of KOA, the echocardiographic calcification score (echo-CCS), and CV risk assessment. Methods This cross-sectional study involved 204 patients diagnosed with KOA and classified according to the Kellgren-Lawrence staging criteria.

Objectives: The objective of the study was to assess the diagnostic performance of the triglyceride-glucose (TyG) index, a surrogate marker of IR, in predicting the presence and severity of HMOD in newly diagnosed untreated hypertensive patients from an academic training and research hospital
Methods: The study included 438 patients with newly diagnosed, untreated hypertension. The control group comprised normotensive individuals matched on a 1:1 ratio based on age, gender, body mass index, and smoking using the nearest neighbor method.
Background: Circadian variations play a pivotal role in both leukocyte trafficking and inflammatory response. This may affect the course of cardiac healing after myocardial infarction (MI).
Aims: The present study investigated the relationship between the systemic immune inflammation (SII) index and the systemic inflammation response index (SIRI), two new inflammation indices integrating white blood cell subsets and platelets, and the time of onset of symptoms in left ventricular adverse remodeling (LVAR) after ST-segment elevation MI (STEMI).
Purpose: The purpose of the present case report is to describe an extremely rare and unusual coronary interarterial communication.
Methods: A 65-year-old female patient admitted with acute coronary syndrome underwent a coronary angiography performed with Judkins technique to obtain standard angiographic views.
Results: We have demonstrated a very rare interarterial communication traversing an unusual retroaortic path between the body of left circumflex artery and the conus branch of the right coronary artery.
Objective: The use of inhaler device (UID) and the satisfaction and adherence of patients to treatment were evaluated by Istanbul city community pharmacists to obtain real-life data from patients with asthma or chronic obstructive pulmonary disease (COPD).
Methods: Pharmacists educated by pulmonary disease specialists asked patients who combined medications with inhaler devices to fill out a questionnaire prepared by the specialists. Each patient's UID was checked, and their errors were corrected by showing them the already prepared standard video of their inhaler device.
Background: To test the hypothesis that smooth muscle cell (SMC) TGF-β (transforming growth factor beta) signaling contributes to maintenance of aortic structure and function beyond the early postnatal period.
Methods: We deleted the TBR2 (type 2 TGF-β receptor) in SMC of 11-month-old mice (genotype -CreER, termed TBR2) and compared their ascending aorta structure and vasomotor function to controls (-CreER, termed TBR2).
Results: We confirmed loss of aortic SMC TBR2 by immunoblotting.

Injury of the lymphatic trunk during abdominal aortic surgery causes leakage of chyle into the peritoneum, resulting in chylous ascites. A 53-year male, who underwent aortobifemoral bypass surgery for Leriche syndrome in our clinic, presented to the Emergency Department two months postoperatively, with complaints of abdominal discomfort, reduced appetite and weight loss. Computed tomography imaging and ultrasound of the abdomen revealed a retroperitoneal fluid collection.

We aimed to compare WMR between NSTEMI patients and matched-controls and to evaluate its predictive value on SYNTAX score.
Methods: Total 175 patients with NSTEMI and 160 age and co-morbidity matched subjects were recruited in our study.
Objective: Non-dipper hypertension (HT) confers greater risk compared with dipper HT. Growth differentiation factor 15 (GDF-15) recently emerged as a novel and independent marker of cardiovascular disease, both in diagnostic and prognostic scopes. Our aim was to evaluate the relationship of circadian blood pressure (BP) pattern with serum GDF-15 level in newly diagnosed HT patients without left ventricular hypertrophy.

Herein, we investigated the direct effects of atorvastatin on gastric smooth muscle tone. Atorvastatin effectively relaxed isolated rat gastric fundus strips precontracted with acetylcholine, potassium chloride, and serotonin.

Herein, we evaluated the effect of iloprost, a prostacyclin (PGI) analogue, against the contractions produced by noradrenaline and potassium chloride on isolated human radial artery. Following the determination of endothelial and vascular relaxing capacities of the arteries, iloprost (10M-10M) was cumulatively applied on rings precontracted submaximally with the spasmogens.

Methods: Thirty patients (13 female, 17 male) with BD and 30 age, sex-matched healthy controls (12 female, 18 male) with no known cardiovascular disease were enrolled in this study. Carotid-femoral PWV and CIMT were measured.
Statins are known to display benefits in various diseases independently from their cholesterol lowering properties. In this study, we investigated the acute effects of atorvastatin on vascular reactivity to various spasmogens in isolated rat aorta. The responses to noradrenaline (NA, 10(-8) -10(-4) m), endothelin-1 (ET-1, 10(-10) -10(-7) m), and potassium chloride (KCl, 10-100 mm) were evaluated in aortic rings pretreated with atorvastatin (10(-7) -10(-4) m, 30 min).

Barnidipine (3 mg/kg/day p.o) was applied to rats after 2 weeks of L-NAME (60 mg/kg/day) administration, and continued for the next 3 weeks concomitantly with L-NAME.
