Human galectin‑3: Molecular switch of gene expression in dermal fibroblasts in vitro and of skin collagen organization in open wounds and tensile strength in incisions .

Understanding the molecular and cellular processes in skin wound healing can pave the way for devising innovative concepts by turning the identified natural effectors into therapeutic tools. Based on the concept of broad‑scale engagement of members of the family of galactoside‑binding lectins (galectins) in pathophysiological processes, such as cancer or tissue repair/regeneration, the present study investigated the potential of galectins‑1 (Gal‑1) and ‑3 (Gal‑3) in wound healing. Human dermal fibroblasts, which are key cells involved in skin wound healing, responded to galectin exposure (Gal‑1 at 300 or Gal‑3 at 600 ng/ml) with selective changes in gene expression among a panel of 84 wound‑healing‑related genes, as well as remodeling of the extracellular matrix.

The possible role of machine learning in detection of increased cardiovascular risk patients - KSC MR Study (design).

Introduction: Currently, just a few major parameters are used for cardiovascular (CV) risk quantification to identify many of the high-risk subjects; however, they leave a lot of them with an underestimated level of CV risk which does not reflect the reality.

Material And Methods: The submitted study design of the Kosice Selective Coronarography Multiple Risk (KSC MR) Study will use computer analysis of coronary angiography results of admitted patients along with broad patients' characteristics based on questionnaires, physical findings, laboratory and many other examinations.

Results: Obtained data will undergo machine learning protocols with the aim of developing algorithms which will include all available parameters and accurately calculate the probability of coronary artery disease.

Genistein Improves Skin Flap Viability in Rats: A Preliminary In Vivo and In Vitro Investigation.

Selective estrogen receptor modulators (SERMs) have been developed to achieve beneficial effects of estrogens while minimizing their side effects. In this context, we decided to evaluate the protective effect of genistein, a natural SERM, on skin flap viability in rats and in a series of in vitro experiments on endothelial cells (migration, proliferation, antioxidant properties, and gene expression profiling following genistein treatment). Our results showed that administration of genistein increased skin flap viability, but importantly, the difference is only significant when treatment is started 3 days prior the flap surgery.

Should open excisions and sutured incisions be treated differently? A review and meta-analysis of animal wound models following low-level laser therapy.

Although low-level laser therapy (LLLT) was discovered already in the 1960s of the twentieth century, it took almost 40 years to be widely used in clinical dermatology/surgery. It has been demonstrated that LLLT is able to increase collagen production/wound stiffness and/or improve wound contraction. In this review, we investigated whether open and sutured wounds should be treated with different LLLT parameters.

Aortic Valve Repair of a Stenotic Unicuspid Aortic Valve in Young Patients.

Background: The unicuspid aortic valve (UAV) is a well-described pediatric congenital abnormality, with incidence of 0.02% in the general population. Bicuspidization has been described as a potential surgical option to repair this defect.

"V" aortoplasty of the proximal descending aorta in the elephant trunk procedure.

Complex pathology of the aorta, especially in patients presenting an aneurysm involving the entire aortic arch and proximal descending aorta has been approached in one or two stages. Surgical management of those with an extremely wide diameter of the proximal descending aorta is not yet well defined. The patient in this case was an asymptomatic 47-year-old female with systemic lupus erythematosus (SLE) associated with aneurysm of the ascending aorta, whose aortic arch and descending aorta had presented only overall weakness (examination by inspection and palpation without histological verification).

One-stage surgical approach to coarctation of the aorta and ascending aortic aneurysm.

Background: Aortic coarctation in adults is sometimes associated with concomitant cardiovascular pathologies which require intervention. The optimal operative approach for such patients remains unsettled. An extra-anatomic aortic bypass from the ascending aorta to the descending aorta via median sternotomy allows simultaneous performance of repair of complex aortic coarctation and concomitant cardiac operation.

Aortic valve-sparing operation versus Bentall and mechanical aortic valve replacement--midterm results.

Objectives: The primary aim of this retrospective study was to evaluate short-term (one-to-six months) and mid-term (six-to-forty-eight months) results of aortic valve-sparing procedures. The second endpoint was to compare the results with the group of patients undergoing mechanical aortic valve replacement during the same period.

Methods: Between April 2008 and May 2012 at our institution, we treated 76 patients either with ascending aorta/root aneurysm/dissection or with isolated aortic regurgitation.

Use of left ventricle assist device in a pregnant woman with acute aortic and coronary dissections.

We report the case of a 31-year-old female in her 32nd week of pregnancy, who experienced an acute type A aortic dissection resulting in severe aortic insufficiency, dissection of the left anterior descending coronary artery, and left ventricular infarct with ejection fraction of 20%. After a successful cesarean section, she underwent a Bentall operation and three-vessel coronary artery bypass grafting. Despite maximal inotropic support, her cardiovascular indices deteriorated postoperatively.

[The effect of water immersion on humoral and urinary parameters in healthy persons and in patients with liver cirrhosis].

The authors subjected 10 healthy subjects and 13 patients inflicted by liver cirrhosis in the stage of vascular decompensation (ascites and/or oedemas) to water immersion (WI). The group of healthy subjects responded during WI by a significant increase of diuresis and sodium diuresis at its maximum in the third hour, which was accompanied by a decrease of plasma aldosterone (PA) and a decrease of atrial natriuretic factor (ANF) and digoxin-like activity (DLA). The decrease of plasma vasopressin (PAVP) was not statistically significant.
