Abstract
Sex hormone-dependent cancers currently contribute to the high number of cancer-related deaths worldwide. The study and elucidation of the molecular mechanisms underlying the progression of these tumors was a double-edged sword, leading to the expansion and development of new treatment options, with the cost of triggering more aggressive, therapy resistant relapses. The interaction of androgen, estrogen and progesterone hormones with specific receptors (AR, ER, PR) has emerged as a key player in the development and progression of breast, ovarian, prostate and endometrium cancers. Sex hormone-dependent cancers share a common and rather unique carcinogenesis mechanism involving the active role of endogenous and exogenous sex hormones to maintain high mitotic rates and increased cell proliferation thus increasing the probability of aberrant gene occurrence and accumulation highly correlated with abnormal cell division and the occurrence of malignant phenotypes. Cancer related hormone therapy has evolved, currently being associated with the blockade of other signaling pathways often associated with carcinogenesis and tumor progression in cancers, with promising results. However, despite the established developments, there are still several shortcomings to be addressed. Triterpenes are natural occurring secondary metabolites biosynthesized by various pathways starting from squalene cyclization. Due to their versatile therapeutic potential, including the extensively researched antiproliferative effect, these compounds are most definitely a cornerstone in the research and development of new natural/semisynthetic anticancer therapies. The present work thoroughly describes the ongoing research related to the antitumor activity of triterpenes in sex hormone-dependent cancers. Also, the current review highlights both the biological activity of various triterpenoid compounds and their featured mechanisms of action correlated with important chemical structural features.

Abstract
PURPOSE Romania has a high prevalence of hypertension (45.1% in 2016). Whether this is attributable to a low rate of treatment adherence-which can aggravate the pathology and reduce patients' quality of life (QoL)-is unknown. To address this point, the present study investigated the factors that influence short- and long-term adherence and QoL in patients with arterial hypertension using a specially designed questionnaire. PATIENTS AND METHODS The study enrolled 289 patients at different stages of hypertension with or without comorbidities. The diagnosis of hypertension was established by the cardiologist, and treatment regimens were communicated by patients to the clinical pharmacist who administered the questionnaire, which comprised 7 domains with variable numbers of items. RESULTS The majority of surveyed patients (57.43%) considered that their capacity for effort was decreased because of their hypertension, with 65.05% reporting that they were affected by symptoms associated with high blood pressure (eg, headache and dizziness). Most patients (71.28%) understood the consequences of discontinuing their medication and the severe complications of hypertension, and 69.55% indicated that they would not stop treatment if they experienced side effects. For 53.28% of patients, social activity was significantly affected by their condition. Only 47.05% of patients underwent regular mandatory medical examinations and 55.36% periodically monitored their blood pressure at home. A regression analysis revealed correlations between specific questionnaire items and patient characteristics. CONCLUSION Nonpharmacologic factors that were shown to influence patients' adherence to treatment and QoL included the level of health education and knowledge of disease complications, self-monitoring of hypertension, and consultation with medical and pharmaceutical healthcare providers regarding hypertension and its treatment.

Abstract
Wounds are among the most common skin conditions, displaying a large etiological diversity and being characterized by different degrees of severity. Wound healing is a complex process that involves multiple steps such as inflammation, proliferation and maturation and ends with scar formation. Since ancient times, a widely used option for treating skin wounds are plant- based treatments which currently have become the subject of modern pharmaceutical formulations. Triterpenes with tetracyclic and pentacyclic structure are extensively studied for their implication in wound healing as well as to determine their molecular mechanisms of action. The current review aims to summarize the main results of in vitro, in vivo and clinical studies conducted on lupane, ursane, oleanane, dammarane, lanostane and cycloartane type triterpenes as potential wound healing treatments.

Abstract
Albendazole is a benzimidazole derivative with documented antitumor activity and low toxicity to healthy cells. The major disadvantage in terms of clinical use is its low aqueous solubility which limits its bioavailability. Albendazole was incorporated into stable and homogeneous polyurethane structures with the aim of obtaining an improved drug delivery system model. Spectral and thermal analysis was used to investigate the encapsulation process and confirmed the presence of albendazole inside the nanoparticles. The in vitro anticancer properties of albendazole encapsulated in polyurethane structures versus the un-encapsulated compound were tested on two breast cancer cell lines, MCF-7 and MDA-MB-231, in terms of cellular viability and apoptosis induction. The study showed that the encapsulation process enhanced the antitumor activity of albendazole on the MCF-7 and MDA-MB-23 breast cancer lines. The cytotoxic activity manifested in a concentration-dependent manner and was accompanied by changes in cell morphology and nuclear fragmentation.

Abstract
The aim of this article is to show how thevpower of statistics and cheminformatics can be combined, in R, using two packages: rcdk and cluster.We describe the role of clustering methods for identifying similar structures in a group of 23 molecules according to their fingerprints. The most commonly used method is to group the molecules using a "score" obtained by measuring the average distance between them. This score reflects the similarity/non-similarity between compounds and helps us identify active or potentially toxic substances through predictive studies.Clustering is the process by which the common characteristics of a particular class of compounds are identified. For clustering applications, we are generally measure the molecular fingerprint similarity with the Tanimoto coefficient. Based on the molecular fingerprints, we calculated the molecular distances between the methotrexate molecule and the other 23 molecules in the group, and organized them into a matrix. According to the molecular distances and Ward 's method, the molecules were grouped into 3 clusters. We can presume structural similarity between the compounds and their locations in the cluster map. Because only 5 molecules were included in the methotrexate cluster, we considered that they might have similar properties and might be further tested as potential drug candidates.

Abstract
Cancer is still a leading cause of death worldwide, while most chemotherapies induce nonselective toxicity and severe systemic side effects. To address these problems, targeted nanoscience is an emerging field that promises to benefit cancer patients. Gold nanoparticles are nowadays in the spotlight due to their many well-established advantages. Gold nanoparticles are easily synthesizable in various shapes and sizes by a continuously developing set of means, including chemical, physical or eco-friendly biological methods. This review presents gold nanoparticles as versatile therapeutic agents playing many roles, such as targeted delivery systems (anticancer agents, nucleic acids, biological proteins, vaccines), theranostics and agents in photothermal therapy. They have also been outlined to bring great contributions in the bioimaging field such as radiotherapy, magnetic resonance angiography and photoacoustic imaging. Nevertheless, gold nanoparticles are therapeutic agents demonstrating its in vitro anti-angiogenic, anti-proliferative and pro-apoptotic effects on various cell lines, such as human cervix, human breast, human lung, human prostate and murine melanoma cancer cells. In vivo studies have pointed out data regarding the bioaccumulation and cytotoxicity of gold nanoparticles, but it has been emphasized that size, dose, surface charge, sex and especially administration routes are very important variables.

Abstract
In recent years, bacterial infections in hospitals have grown particularly due to the development of antibiotic resistance. Recent research targets the discovery of new antibiotics that exhibit broad spectrum of action without adverse effects or minimizing adverse effects. In this study, the activity of biosynthesized silver nanoparticles against three bacteria commonly found in infectious diseases in the ORL sphere was evaluated. The recorded data revealed an activity comparable to that of the standard antibiotics used in these types of infections, with the observation that the activity of the nanoparticles could also be observed in the particular cases of antibiotic resistance.

Abstract
The present study was conducted in order to evaluate the biological activity of thyme aqueous extract as compared to the silver nanoparticles obtained on it on four different cancer lines: non-melanoma skin cancer (A431 cell line), melanoma skin cancer (A375cell line), hormone dependent breast cancer (MCF-7 cell line), and non-hormone dependent breast cancer (MDA-MB-231 cell line). Of particular importance in the study of biological activity is the chemical composition. Formulas rich in compounds of classes like those of flavonoids are recognized for their efficacy and important antioxidant effect. The extract tested at various concentrations ranging from 10-1000 �g/mL exhibited a pronounced effect only on MCF-7 cells at the highest concentration tested and regarding the biosynthesized silver nanoparticles, the effect can be noted even at 1 � M also only in the case of MCF-7 cells.

Abstract
Betulinic acid (BA) was demonstrated to be a very promising anticancer agent against various tumor cell lines such as breast, colon, lung, and brain. Despite its strong cytotoxic effect, betulinic acid exhibits low water solubility, feature that is reflected in its poor bioavailability. To overcome these drawbacks, numerous strategies were conducted to improve its physicochemical and pharmacokinetic profile, among which cocrystalization emerged as a promising approach. Thus, our work consisted in obtaining slowly grown cocrystals of BA and ascorbic acid (BA+VitC) in isopropyl alcohol obtained in a hydrothermal experiment. The newly formed cocrystals were characterized by physico-chemical methods such asSEM, DSC, XRPD, and FT-IR spectroscopy demonstrating BA+VitC cocrystal formation while their antioxidant activity revealed an additive antioxidant effect. To investigate the biological effect, BA+VitC cocrystals were tested on HaCat (immortalized human keratinocytes), B164A5 and B16F0 (murine melanoma), MCF7 and MDA-MB-231 (human breast cancer), and HeLa (cervical cancer) cell lines. Results of BA upon the tested tumor cell lines, after co-crystallization with vitamin C, indicated a superior cytotoxic effect with the preservation of a good selectivity index assumably due to an improved BA water solubility and consequently an optimized bioavailability.

Abstract
As we know today, cancer is a disease caused by the uncontrolled growth of a single cell. This development is triggered by mutations, changes in DNA that affect genes in such a way that they increase cancer cells. In the present study, an experimental model based on skin carcinoma xenograft mice was developed and tested. There were studied: the mice weight, the tumor volume, and the evolution of different skin parameters such as transepidermal water loss (TWL), erythema and the hydration level of stratum corneum; mice were divided in four groups: a control group, a group of mice injected with physiological saline solution, another one with immunosuppression, and a group of mice with immunosuppression and xenograft of A375 cells. The results indicate that administration of cyclophosphamide significantly reduced the number of neutrophils and lymphocytes and last two mice groups revealed more pronounced modifications of skin parameters compared to first two groups.

Abstract
Intensive care units (ICUs) are often referred to as the epicentre of infection diseases in a hospital. Many studies highlighted the importance of using local antimicrobial resistance data, to guide empirical antibiotic therapy. As a consequence, the present study is particularly important, especially in the current context, when we are witnessing an ascending trend of antimicrobial resistance. Beta-lactams are the most frequently used class of antibiotics for treating patients infected with various germs. The aim of this study is to analyse the modalities by which microorganisms become resistant to antibiotics of this class, in an intensive care unit of a Romanian university hospital. During the period between January, the 1st 2012 and December the 31st 2013, a prospective study was conducted in the largest ICU from the Western part of Romania. Various resistance mechanisms to beta-lactam antibiotics were detected. Among these, there is great concern regarding the high number of extended-spectrum beta-lactamase producing microorganisms, as in most cases they determine the use of carbapenems, thus increasing the risk of occurrence and dissemination of carbapenemase-producing bacteria.

Abstract
Background Due to the vulnerable nature of its patients, the wide use of invasive devices and broad-spectrum antimicrobials used, the intensive care unit (ICU) is often called the epicentre of infections. In the present study, we quantified the burden of hospital acquired pathology in a Romanian university hospital ICU, represented by antimicrobial agents consumption, costs and local resistance patterns, in order to identify multimodal interventional strategies. Methods Between 1st January 2012 and 31st December 2013, a prospective study was conducted in the largest ICU of Western Romania. The study group was divided into four sub-samples: patients who only received prophylactic antibiotherapy, those with community-acquired infections, patients who developed hospital acquired infections and patients with community acquired infections complicated by hospital-acquired infections. The statistical analysis was performed using the EpiInfo version 3.5.4 and SPSS version 20. Results A total of 1596 subjects were enrolled in the study and the recorded consumption of antimicrobial agents was 1172.40 DDD/ 1000 patient-days. The presence of hospital acquired infections doubled the length of stay (6.70 days for patients with community-acquired infections versus 16.06/14.08 days for those with hospital-acquired infections), the number of antimicrobial treatment days (5.47 in sub-sample II versus 11.18/12.13 in sub-samples III/IV) and they increased by 4 times compared to uninfected patients. The perioperative prophylactic antibiotic treatment had an average length duration of 2.78 while the empirical antimicrobial therapy was 3.96 days in sample II and 4.75/4.85 days for the patients with hospital-acquired infections. The incidence density of resistant strains was 8.27/1000 patient-days for methicilin resistant Staphylococcus aureus, 7.88 for extended spectrum β-lactamase producing Klebsiella pneumoniae and 4.68/1000 patient-days for multidrug resistant Acinetobacter baumannii. Conclusions Some of the most important circumstances collectively contributing to increasing the consumption of antimicrobials and high incidence densities of multidrug-resistant bacteria in the studied ICU, are represented by prolonged chemoprophylaxis and empirical treatment and also by not applying the definitive antimicrobial therapy, especially in patients with favourable evolution under empirical antibiotic treatment. The present data should represent convincing evidence for policy changes in the antibiotic therapy.

Abstract
Computer-aided drug design plays an important role in modern day drug discovery, because it provides a more specific range for active compound chemical synthesis in detriment of the traditional ways of drug discovery. Relevant studies proved that the epidermal growth factor receptor (EGFR) and vascular endothelial growth factor receptor (VEGFR) are important targets for inhibition, in finding new molecules with potential anticancer activity. The aim of the present study was to create a compound library and submit this set of molecules to a docking-based virtual screening process. Molecular docking was carried out using OEDocking HYBRYD, a software with an improved scoring algorithm, which uses a ligand-based scoring function. The obtained results revealed some molecular structures that showed good predicted binding affinity towards their respective protein targets.

Abstract
BACKGROUND In the last decades, the studies performed on the field of endothelial dysfunction confirmed the fact that the starting point of this pathology is the inflammation. Several inflammatory biomarkers had been discovered and studied, ones showing systemic inflammation, and others being more specific biomarkers and showing the local inflammation. Pentraxin-3 (PTX3) is a new inflammatory biomarker, from the same family as high-selectivity C-reactive protein (hs-CRP), but it is a more specific biomarker, due to its local production: the endothelial cells and not the liver like in the case of hs-CRP. AIMS Several antihypertensive classes of drugs seem to have a positive impact on reducing the local endothelial inflammation, beyond their effect of lowering the blood pressure, so this study aims to analyze the effect of candesartan on the two inflammatory biomarkers: PTX3 and CRP, compared with other antihypertensive drugs, in hypertensive patients with endothelial dysfunction. METHODS A total of 365 patients were included in the study: 127 hypertensive patients were under treatment with candesartan, 134 patients were under treatment with other hypotensive medication (beta blockers, calcium channel blockers, and diuretics), both groups with controlled values of blood pressure, and 104 were normotensive persons. Classical methods of assessing the endothelial function were correlated with these biochemical markers. RESULTS The patients treated with candesartan had a significant lower value of PTX3 and hs-CRP, compared with those under treatment with other antihypertensive medication as follows: PTX3: 0.61 ± 0.49 vs 0.95 ± 1.04 ng/ml, P = 0.006 and hs-CRP: 0.19 ± 0.20 vs 0.20 ± 0.22 mg/dl, P = 0.54. CONCLUSIONS Candesartan decreases PTX3 and hs-CRP plasma levels more powerful than other classes of antihypertensive drugs (beta blockers, calcium channel blockers, and diuretics), so we may assume that candesartan has a more potent action in reversing endothelial dysfunction and that it offers a higher vascular protection than other classes of antihypertensive drugs. We are suggesting that this new biochemical marker, PTX3, might be better and more specific marker for endothelial dysfunction, than hs-CRP.

Abstract
Thrombospondin-1 (TSP-1) is a potent endogenous inhibitor of both physiological and pathological angiogenesis, widely studied as a target in drug development for treating cancer. Several studies performed in the cardiovascular field on TSP-1 are contradictory, the role of TSP-1 in the physiopathology of cardiovascular disorders (CVDs) being, for the moment, incompletely understood and may be due to the presence of several domains in its structure which can stimulate many cellular receptors. It has been reported to inhibit NO-mediated signaling and to act on the angiogenesis, tissue perfusion, endothelial cell proliferation, and homeostasis, so we aimed to quantify the effect Perindopril has on TSP-1 plasma levels in hypertensive patients with endothelial dysfunction in comparison with other antihypertensive drugs, such as beta blockers, calcium channel blockers, and diuretics, in a chronic treatment. As a conclusion, patients under treatment with Perindopril had increased plasma levels of TSP-1 compared with other hypertensive patients and with the control group. The results of this study confirms the pleiotropic properties of Perindopril: anti-proliferative, anti-inflammatory, with effects showed by quantifying a single biomarker: TSP-1.

Abstract
BACKGROUND Systemic sclerosis (SSc) is an autoimmune disease where thickening of the skin can lead to reduced body function and limitations in activities. Severe forms can also affect and seriously damage inner organs. Patient-centred rehabilitation emphasises considerations of patients' background, experience and behavior which highlights the need to know if patient-reported outcome measures (PROMs) include such personal factors. AIM To identify and describe personal factors in the experiences of functioning and health of persons with SSc and to examine if and to what extent PROMs in SSc research cover these factors. DESIGN Data from a qualitative study with focus group interviews were analysed. PROMs in SSc research were identified in a literature review between 2008-2013. SETTING Participants were recruited from outpatient clinics at rheumatology department. POPULATION Sixty-three patients with SSc from four European countries participated. METHODS Data from interviews were analysed using a structure of personal factors developed by Geyh et al. Identified PROMs were analysed and linked to main concepts, related to the personal factors, found in the interview data. RESULTS Nineteen main concepts were related to the area "patterns of experience and behaviour" in the personal factor structure, 16 to "thoughts and beliefs", nine to "feelings", one to "motives" and one to "personal history and biography", respectively. Among the 35 PROMs identified, 15 did not cover any of the identified concepts. Concepts within the area "feelings" were mostly covered by the PROMs. Five of the PROMs covered "patterns of experience and behaviour", while "motives" and "personal history and biography" were not covered at all. Four of the identified PROMs covered concepts within the areas "feelings", "thoughts and beliefs" and "patterns of experience and behaviour" in the same instrument. The Illness Cognition Questionnaire and Illness Behaviour Questionnaire were such PROMs. CONCLUSION Patterns of experience and behaviour had the highest number of concepts related to personal factors, but few of the PROMs in SSc research covered these factors. Only a few PROMs covered several personal factors areas in the same instrument. CLINICAL REHABILITATION IMPACT The results would be of value when developing core sets for outcome measurements in SSc.

Abstract
UNLABELLED The main changes of the plasma lipid profile in patients with endothelial dysfunction are the increased triglyceride content of the lipoprotein remnant particles, the presence of the small and dense LDL particles and the decreasing of the HDL-cholesterol level. MATERIAL AND METHOD Considering these observations, we performed "in vitro" experiments using human mammary artery rings, in order to examine the effect of the lipoprotein "remnants" on endothelium-dependent vasodilatation induced by cumulative doses (10(-9) M - 10(-4) M) of adenosine (ADP) and to study the effect on endothelial--independent vasodilatation induced by cumulative doses (10(-9) M-10(-4) M) of sodium-nitropruside (NSP), respectively. RESULTS Our results showed that 1 hour pre-incubation with triglyceride--rich lipoprotein remnants diminished the endothelial-dependent vasodilator response to ADP, but it has not modified the endothelial-independent vasodilator response to NSP. Vascular response was expressed as maximal vasodilatation from the 10(-4)M phenilephrine (PE) induced pre-contraction, considered as reference. In the case of ADP, the maximal vasodilatation was ranged in 36.50% +/- 10.81% interval, comparing with the control group that presented a maximal vasodilatation of 66.15% +/- 19.41% (p < 0.005). In the case of NSP the maximal vasodilatation was ranged in 99.78% +/- 10.53% interval, comparing with the control that presented a maximal vasodilatation of 98.99% +/- 12.45% (p = 0.44). One hour co-incubation of the rings with a solution containing lipoprotein remnants (1% oxidized IDL (ox-IDL) and antioxidant factor (150 U/mL 10(-4) M Superoxid dismutase (SOD) significantly reduced the impairment of the vasodilatation response to ADP. Maximal vasodilatation of ox-IDL and SOD coincubated human mammary artery rings was 58.50% +/- 10.63% compared to the control, were the maximal vasodilatation was 66.15% +/- 19.41% (p < 0.01), but has not modified the vasodilatation response to NSP (99% +/- 0.53% vs control 98.99% +/- 12.45%, p = 0.56). CONCLUSION The endothelial dysfunction induced by the triglyceride-rich lipoprotein "remnants", could contribute to the pathogenesis of atherosclerosis and the treatment with high doses of antioxidants could "protect" the endothelium against the pro-atherogenic action of the lipoprotein "remnants".

Abstract
UNLABELLED Oxidation of LDL plays an important role in the pathogenesis of atherosclerosis. Increased wall thickness precedes plaque formation and noninvasive B-mode ultrasonographic measurement of IMT is considered a useful marker of the development of the carotid atherosclerosis. MATERIAL AND METHOD The present study was designed to assess the association of oxidized low-density lipoprotein (ox-LDL) with carotid intima-media thickness (IMT) in hypertensive patients. Oxidized LDL (enzyme-linked immunosorbent assay, Elisa) and carotid IMT (high-resolution B-mode ultrasonography) were assessed in 74 patients, aged between 45 and 65 years, diagnosticated with arterial hypertension. RESULTS We observed significantly higher plasma levels of total cholesterol (236.32 +/- 41.96 mg/dl), LDL cholesterol (166.92 +/- 38.55 mg/dl), triglycerides (180.79 +/- 72.05 mg/dl) and low plasma levels of HDL-cholesterol (33.24 +/- 7.99 mg/dl) in all patients. We noticed higher plasma levels of ox-LDL (77.34 +/- 24.78 mg/dl) and carotid IMT was increased (1.41 +/- 0.31 mm). The statistically analysis done using Pearson's test and Student's t - test indicated that there were correlations of ox-LDL with: IMT (p < 0.05, r = 0.408), total cholesterol (p < 0.05, r = 0.498), LDL-cholesterol (p < 0.05, r = 0.527), triglycerides (p < 0.05, r = 0.385) and HDL-cholesterol (p < 0.05, r = -0.442). CONCLUSION Higher plasma levels of ox-LDL were associated with increased carotid IMT in hypertensive patients. Measurement of plasma Ox-LDL and carotid IMT may represent useful markers for atherosclerosis and may represent potential targets for therapeutic interventions.
