Abstract
This study does not propose to elucidate how adiponectin secretion is regulated, but how its adiponectin concentration is an indicator of heart disease. About adiponectin, it is not known whether it is functionally an enzyme, or very likely a cytokine/chemokine/hormone, secreted by fat cells/adipocytes in the abdomen. Abdominal fat secretes 67 hormones, and all of which cause disease. For example, adiponectin generates diabetes and ischaemic heart disease via dyslipidemia. Based on clinical symptoms, electrocardiographic and echocardiographic parameters, a group of 208 patients with diastolic cardiac dysfunction with or without preserved systolic function, developed on a background of painful chronic ischaemic heart disease, stable angina on exertion, was constituted. The serum levels of adiponectin, total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides were measured. Using the identified values, it was appreciated whether adiponectin correlates with the type of any of the two conditions, so that it can be recognised as a diagnostic and risk stratification marker.

Abstract
At the level of the genital system, ovarian neoplasm is the most frequent cause of morbidity and mortality. In the specialized literature, the coexistence of an inflammatory process is admitted from the early stages of the evolution of this pathology. Starting from the importance of this process, both in determinism and in the evolution of carcinogenesis and summarizing the field of knowledge, for this study we considered two objectives: the first was the presentation of the pathogenic mechanism, through which chronic +ovarian inflammation is involved in the process of carcinogenesis, and the second is the justification of the clinical utility of the three parameters, accepted as biomarkers of systemic inflammation: neutrophil-lymphocyte ratio, platelet lymphocyte ratio, and lymphocyte-monocyte ratio in the assessment of prognosis. The study highlights the acceptance of these hematological parameters, with practical utility, as prognostic biomarkers in ovarian cancer, based on the intrinsic link with cancer-associated inflammatory mediators. Based on the data from the specialized literature, the conclusion is that in ovarian cancer, the inflammatory process induced by the presence of the tumor, induces changes in the types of circulating leukocytes, with immediate effects on the markers of systemic inflammation.

Abstract
The myeloperoxidase levels of 208 patients with ischemic heart disease hospitalized for congestive heart failure were tested at admission, and discharge after 14 days. The calculations for the serum average concentration/lot/date, were made, subsequent, using the values of the tested parameters regarding MPO (admission and discharge) the mean concentration/lot was made, regardless of time of determination. The calculated average values analyses of the three MPO serum parameters were constantly elevated and permanently matched the myocardial contractility deficiency class. The integrated data of the study, allows us to propose the MPO’s circulating concentration as a diagnosis and risk assessment biomarker in the etiology of myocardial ischemia for chronic cardiac failure.

Abstract
In a group of 208 patients with chronic ischaemic heart disease, the variation of A2-associated-LDL phosphatase (Lp-PLA2) serum concentration values was analysed in dynamics at a two-week interval. The conclusion of the study is that the values of serum concentration of Lp-PLA2 can be accepted as a biomarker with diagnostic specificity for chronic ischaemic heart disease, a parameter of real utility in medical practice, both in situations where the patient, although clinically reporting the existence of angina pectoris, does not show specific changes on an EKG, and for the assessment of the response to personalised therapy.

Abstract
The study is motivated by the existence of a still controversial etiopathogen on Burning Mouth Syndrome. The objective of the study, which is carried out on a group of 103 sick of both sexes, presenting the Burning Mouth Disorder - the primary form, is to identify the prevalence of the disease and establish possible correlations with coexistence of age, gender and dyslipidemia as factors that can be considered as favoring the installation non-specific oral allergy. The conclusions of the research constitute an argument for admitting the hypothesis of the existence of a neuronal irrigation deficiency, manifested both at the conductive sensory fibers of the influx and, more preferably, at the sensory-sensorial cortex for pain and taste, or only at one of these levels. According to the hypothesis, neuronal suffering consists in a deficiency of energy production and use, induced by excessively local reactive oxygen species, through irrigation, developed by the presence of arteriosclerosis.

Abstract
The present study looks at serum concentration levels of myeloperoxidase (MPO) and high-sensibility C Reactive Protein (hs-PCR) concentrations in 91 patients who presented thoracic pain localised on the sub-clavicular left side, which bothered them several times a day, where an episode lasted up to 30 minutes. Additional preclinical investigations revealed normal resting state/effort electrocardiograms, and the cardiac ultrasound revealed a diastolic cardiac dysfunction with a conserved ejection fraction. The conclusion of our study is that undertaking the exploratory tetrad (electrocardiogram, echocardiogram, serum dosage of MPO and hs-PCR) in patients who present anterior left pain, regardless of the degree of intensity, allows stratifying risks, at least through early detection of an existent diastolic cardiac dysfunction with conserved ejection fraction, which recommends changes in diet and lifestyle along with therapy.

Abstract
The justification for choosing and this enzyme marker to investigate the variation in serum concentration is supported by at least two arguments: cytokine myeloperoxidase at the level of the hypocritical myocardium, with or without contractile deficiency, can be secreted by any type of component or resident in the myocardium In cardiac failure, one of the forms that responds to the oxidative stress existing in the disease is MPO secretion that occurs early after some authors even during Class I contractile myocardial deficiency (NYHA classification).

Abstract
The determined values of paraoxonase-1 serum concentration in 91 patients with cardiac insufficiency with a preserved ejection fraction with etiology of ischemic cardiopathy showed that this as an antioxidant enzyme may be accepted as a diagnostic biomarker, the assessment of the response to therapy, but also risk in this condition. Reporting circulating values of isozyme to the sex of patients revealed a very good correlation for males, which would confer PON1 specificity of sex to such a condition.

Abstract
The study analyses the significance of the plasmatic values of the OPN dosed to 91 people suffering from diastolic cardiac dysfunction with preserved ejection fraction, thus revealing significant growths of its level compared to the normal value. Despite being a clinical research, its conclusions are a breakthrough, differing from the results of other studies published in the relevant medical literature. We can make this assertion because this study analyses the clinical information given by the circulating values of the OPN, based on experimental models (animals), or on patients with congestive heart failure, which can be identified with the existence of a low systolic flow. The results of our study allow us to assert that the plasmatic values of this glycoprotein lead to its acceptance in the medical practice as a new biomarker that provides indicators regarding the stratification of risk with the patients suffering from heart failure of the diastolic dysfunction type, but whose systolic flow is preserved.

Abstract
The study on a subset of 208 patients with diastolic dysfunction with the ejection fraction preserved discusses the possibility of circulating CRP levels to be accepted as a diagnostic marker. In order to carry out a comparative analysis of the significance of hsCRP serum values, the study also included a subgroup labeled as control, consisting of the same number of patients, but diagnosed only with painful chronic ischemic cardiopathy - a stable form of angina pectoris. The conclusion of the study is that the circulating level of hs-CRP can be accepted as a diagnostic marker for both ischemic cardiopathy and diastolic dysfunction with preserved ejection fraction. The result, corroborated with data from other studies that recognize the serum concentration of hs-CRP as a predictor marker in cardiovascular disease, supports its usefulness as a marker for cardiac insufficiency with a history of ischemic cardiopathy, without being a marker for assessing the degree of myocardial contractility deficiency.

Abstract
The current study was conducted on a sample of 91 patients diagnosed with diastolic dysfunction (DD) with preserved systolic function caused by a painful chronic ischaemic cardiopathy – angina pectoris stable at the effort. The diagnosis was established following anamnesis, electrocardiogram, and echocardiography. Myeloperoxidase (MPO) serum levels were assessed in all patients and then these values were correlated with some of the echocardiography parameters that proved the mentioned diagnosis. In conclusion, the execution of this investigation triad (electrocardiogram, echocardiography, and MPO) allows:Stratifying the patients depending on the disease risk by early detecting of any possible DD with preserved systolic function. The use of the MPO increased circulating levels as a biomarker for diagnosis and risk due to the statistically significant correlation between those and the results of the other two aforementioned paraclinical investigation.

Abstract
The gamma-glutamyltransferase (GGT) is recognized in medical practice as a useful indicator for the detection of liver lesions, especially those induced by the excessive consumption of alcoholic or cholesterol-associated drinks. The present study, although it includes a very small number of cases diagnosed with colon diverticulosis-diverticulitis associated with polyposis at the same intestinal level, identifies the presence of increased circulating concentrations of this enzyme in the serum. Its serum levels are tracked “dynamically” throughout a year after the diagnosis and start of the therapy. The study calls into question the release of the enzyme from the edge of the enterocytes’ brush-like edge, leading to the pathogenic disturbance of regional redox homeostasis. The hypothesis gives the circulating values of GGT predictive value for cellular oxidative stress, as well as for indirectly expressing the glutathione level in cytosol.

Abstract
For the medical practice, our manuscript acts as a signal, despite only presenting three cases which feature the association between hepatocytolysis, haemolysis and hypermagnesaemia. This clinical–biologic triad was highlighted with the workers who through the nature of their profession were exposing themselves periodically to vapours which contained copper sulphate neutralised with calcium hydroxide, a fungicide used for fruit trees. We are exclusively assessing the haematological perturbation. In this aetiological context, the generating mechanism for haemolysis is very probable biochemical, where hypercupraemia interferes with cellular antioxidant defence mechanisms. Hypothetically, the role of the redox homeostasis disorder in the intravascular destruction of erythrocytes is sustained, and particularly the coexistence of cell cytolysis in the medullary erythroid compartment, which can be assimilated with a possible ineffective erythropoiesis.

Abstract
As defined by WHO experts, disease involves a change of the physical, mental and social welfare, generating chronic stress condition if unresolved. One of the symptoms almost constantly found in any condition is pain. This feeling manifests differently depending on the subjective perception. The burning mouth syndrome (BMS) is included in such a framework. The BMS is considered as one of the characteristic states of chronic stress syndromes associated with nonspecific clinical manifestations and requires special medical attention in terms of assessing and treating the condition. However, the insufficient knowledge of its etiopathogenic mechanisms requires comprehensive research undertaken on such a subject.

The process is complex, including the first functional cell mass reduction (in particular, apoptosis and necrosis), and on the other hand the development of fibrosis process with a starting point at the extracellular matrix. Both mechanisms that take place are caused by etiological factors, enhanced, favoring the developer cytokines mediated by inflammatory processes such as premature death and functional constituent cells of the body; secondly the inflammation leads to fibrosis. The article review is a summary of the knowledge that exist at the level of the anatomical organ remodeling.

Abstract
The growth of Mycobacterium tuberculosis is strongly inhibited by weak acids although the mechanism by which these compounds act is not completely understood. A series of substituted benzoic acids, nipecotic acid, ortho- and para-coumaric acid, caffeic acid and ferulic acid were investigated as inhibitors of three β-class carbonic anhydrases (CAs, EC 4.2.1.1) from this pathogen, mtCA 1 (Rv1284), mtCA 2 (Rv3588c) and mtCA 3 (Rv3273). All three enzymes were inhibited with efficacies between the submicromolar to the micromolar one, depending on the scaffold present in the carboxylic acid. mtCA 3 was the isoform mostly inhibited by these compounds (K(I)s in the range of 0.11-0.97 µM); followed by mtCA 2 (K(I)s in the range of 0.59-8.10 µM), whereas against mtCA 1, these carboxylic acids showed inhibition constants in the range of 2.25-7.13 µM. This class of relatively underexplored β-CA inhibitors warrant further in vivo studies, as they may have the potential for developing antimycobacterial agents with a diverse mechanism of action compared to the clinically used drugs for which many strains exhibit multi-drug or extensive multi-drug resistance.

Abstract
A series of heterocyclic mercaptans incorporating 1,3,4-thiadiazole- and 1,2,4-triazole rings have been prepared and assayed for the inhibition of three physiologically relevant carbonic anhydrase (CA, EC 4.2.1.1) isozymes, the cytosolic human isozymes I and II, and the transmembrane, tumor-associated hCA IX. Against hCA I the investigated thiols showed inhibition constants in the range of 97 nM to 548 microM, against hCA II in the range of 7.9-618 microM, and against hCA IX in the range of 9.3-772 microM. Thiadiazoles were generally more active than triazoles against all investigated isozymes. Generally, the best inhibitors were the simple derivative 5-amino-1,3,4-thiadiazole-2-thiol and its N-acetylated derivative, which were anyhow at least two orders of magnitude less effective inhibitors when compared to the corresponding sulfonamides, acetazolamide, and its deacetylated derivative. An exception was constituted by 5-(2-pyridylcarboxamido)-1,3,4-thiadiazole-2-thiol, which is the first hCA I-selective inhibitor ever reported, possessing an inhibition constant of 97 nM against isozyme I, and being a 105 times less effective hCA II inhibitor, and 3154 times less effective hCA IX inhibitor. Thus, the thiol moiety may lead to effective CA inhibitors targeting isozyme I, whereas it is a less effective zinc-binding function for the design of CA II and CA IX inhibitors over the sulfonamide group.

Abstract
Carbonic anhydrases (CAs, EC 4.2.1.1) are wide spread enzymes, present in mammals in at least 14 different isoforms: some of these isozymes are cytosolic (CA I, CA II, CA III, CA VII), while others are membrane-bound (CA IV, CA IX, CA XII and CA XIV); CA V is mitochondrial, and CA VI is secreted in the saliva. Three acatalytic forms are also known (CARP VIII, CARP X and CARP XI). Several important physiological and physio-pathological functions are played by many CA isozymes, which are strongly inhibited by aromatic and heterocyclic sulfonamides. The catalytic and inhibition mechanisms of these enzymes are understood in great detail, and this greatly helped in the design of potent inhibitors, some of which possess important clinical applications. The use of such CA inhibitors (CAIs) as antiglaucoma drugs will be discussed in detail, together with the recent developments that led to isozyme-specific and organ-selective inhibitors. A recent discovery is connected with the involvement of CAs and their sulfonamide inhibitors in cancer: many potent CAIs were shown to inhibit the growth of several tumor cell lines in vitro and in vivo, constituting thus interesting leads for developing novel antitumor therapies. Future prospects for drug design applications for inhibitors of these ubiquitous enzymes will be dealt with. Although activation of CAs has been a controversial issue for some time, recent kinetic, spectroscopic and X-ray crystallographic experiments offered an explanation for this phenomenon, based on the catalytic mechanism. It has been demonstrated recently, that molecules that act as carbonic anhydrase activators (CAAs) bind at the entrance of the enzyme active site participating in facilitated proton transfer processes between the active site and the reaction medium. In addition to CA II - activator adducts, X-ray crystallographic studies have also been reported for ternary complexes of this isozyme with activators and anion (azide) inhibitors. Structure-activity correlations for diverse classes of activators will be discussed for the isozymes for which the phenomenon has been studied, i.e., CA I, II, III and IV. The possible physiologic relevance of CA activation will also be addressed, together with the recent pharmacological applications of blood CA isozymes activators, as potential memory enhancing drugs.

Abstract
N-4-Nitrobenzyl-beta-alanine was reacted with alkyl/arylsulfonyl halides, followed by conversion of the COOH to the CONHOH group. Structurally related compounds were obtained by reaction of N-4-nitrobenzyl-beta-alanine with aryl isocyanates, arylsulfonyl isocyanates or benzoyl isothiocyanate, followed by similar conversion of the COOH into the CONHOH moiety. Another subseries of derivatives was prepared from sulfanilyl- or metanilyl-4-nitrobenzyl-beta-alanine by reaction with arylsulfonyl isocyanates, followed by the introduction of the hydroxamate moiety. The new compounds were assayed as inhibitors of four matrix metalloproteinases (MMPs), MMP-1, MMP-2, MMP-8 and MMP-9, and of the Clostridium histolyticum collagenase (ChC). Some of the prepared hydroxamate derivatives proved to be very effective collagenase/gelatinase inhibitors, depending on the substitution pattern at the sulfonamido moiety. Substitutions leading to the best inhibitors of MMP-1, a short-pocket enzyme, were those involving pentafluorophenylsulfonyl or 3-trifluoromethyl-phenylsulfonyl at P(1') (K(I) of 3-5 nM). For MMP-2, MMP-8 and MMP-9 (deep-pocket enzymes), the best inhibitors were those containing perfluoroalkylsulfonyl- and substituted-arylsulfonyl moieties, such as pentafluorophenylsulfonyl, 3- and 4-protected-aminophenylsulfonyl-, 3- and 4-carboxy-phenylsulfonyl-, arylsulfonylureido- or arylsulfonylureido-sulfanilyl-/metanilyl moieties at P(1'). Bulkier groups in this position, such as 1- and 2-naphthyl-, substituted-naphthyl or quinoline-8-yl- moieties, among others, led to less effective MMP/ChC inhibitors. The best ChC inhibitors were again those containing pentafluorophenylsulfonyl, 3- and 4-protected-aminophenylsulfonyl P(1') groups. This study demonstrates that the 4-nitrobenzyl moiety, investigated here for the first time, is an efficient P(2') anchoring moiety, whereas the beta-alanyl scaffold can successfully replace the alpha-amino acyl one, for obtaining potent MMP/ChC inhibitors.
