The usage of prosthetic devices in the surgery of parietal defect is, nowadays, essential for a good abdominal wall recovery and prevention of the hernia recurrence. A good and suitable textile allograft should poses one or more, ideally all, of the following characteristics: pliable, strong, non-allergenic and with perfect tissue integration behavior. The aim of this paper is to evaluate the immediate and long term tissue reaction of different textile allografts used in open surgery of inguinal hernia repair.

Because endodontic pathology is caused due to bacterial contamination of the root canal system, endodontic treatment should focus on eliminating microorganisms in root canals. For more than 70 years Calcium Hydroxide has an important role in antimicrobial endodontic therapy. The use of calcium hydroxide is limited by the incomplete removal thereof, a residue covering 20% to 45% of the ductal wall, even after irrigation with NaOCl or EDTA. This study aims to evaluate the removal of calcium hydroxide in root canals using two different techniques.

The present paper was aimed at achieving a study on carbon nanotubes-reinforced composites and involved obtaining and characterization of composites based on epoxy compounds modified with hydroxyl groups-containing compounds (glycols). In order to obtain high flexibility epoxy resins-based composites, carboxyl- functionalized MWCNTs were used as filler at a concentration of 0.5 %. The influence of the weight concentration in CNTs on the mechanical and thermo -mechanical properties of the epoxy compounds was evaluated in comparison to mechanical properties of the DGEBA standard composites reinforced with 0.5 % MWCNT.

Sealing the pits and fissures of posterior teeth represents a local and specific method of caries prevention. The aim of this study was to evaluate the adhesion of two materials used in sealing pits and fissures: Pitt and Fisure and Fissurit FX (Voco), with the help of the scanning electronic microscope (SEM). The results of the study revealed a much higher quality of the Fissurit FX (Voco) product both in terms of adhesion to the enamel and material homogeneity. The Pitt and Fisure product showed a high degree of detachment from the enamel, marginal infiltration, large particles and a high concentration of inorganic particles.

Gestational diabetes mellitus (GDM), defined by the occurrence or discovery of glucose intolerance during pregnancy is associated with higher risk of perinatal complications and long-term development of chronic diseases both in the mother and her child. Recent data suggest that women diagnosed earlier in pregnancy, even having more risk factors, develop fewer complications. The aim of the current study is to analyse biochemical markers that play a role in the pathophysiology of GDM and could lead to an early diagnosis. The authors performed a case-control study on 50 pregnant women that finally developed GDM and 50 pregnant women with risk factors for GDM which did non develop the disease. In all cases there were monitored a series of biochemical markers like glycated haemoglobin (HbA1c), sex hormone binding globulin (SHBG), magnesium (Mg), C-reactive protein (CRP), plasma insulin level, and pregnancy-associated plasma protein A (PAPP-A). All these factors were statistically analysed using univariate and multivariate tests in order to evaluate their predicting value. The combination of traditional risk factors with HBA1c, SHBG, PAPP-A and CRP proved significant prognosis value (75% sensitivity rate, 9% false positive rate) for GDM. In conclusion, these four biochemical markers available in early pregnancy have improved the performance of predicting models concerning the development of severe GDM needing insulin treatment and predisposing to maternal and foetal complications.

The aim of this study was to determine the incidence of hypoandrogenenic to male patients with S.Met., in the context of cardiovascular risk factors. It performed description of a correlation with diagnostic components of S.Met., and specifying an interrelated male hypogonadism with each of the major cardiovascular risk factors.

The aim of this study was to evaluate shear bond strength and adhesive remnant index between two different brands of adhesive systems and brackets. The adhesive systems were represented by Opal Bond MV Composite and Opal Seal (Ultradent), respectively the fluoride releasing Transbond light cure adhesive paste and Transbond XT (3M). The utilised brackets were Avex metal bracket system (Ultradent), respectively Unitek™ Miniature Twin Metal Brackets (3M). The study was realized on 4 groups of extracted teeth: the first and second groups by using the products of the manufacturer Ultradent, respectively 3M, and the third and fourth groups by using the adhesive system of one manufacturer and the brackets of the other manufacturer. The study revealed that the use of adhesive system and brackets of the same manufacturer may increase the shear bond strength and decrease the adhesive remnant index.

This study summarizes the recent achievements in the development of alternative cement free binder materials (cementless) called alkali activated binder or more popularly known as geopolymers. The history of the development of alkali activated binder and recent terminology are discussed. The influence of the type of the base materials on the properties of goepolymers are thoroughly reviewed. The effect of composition and concentration of alkali and curing temperature on the properties and mechanical behavior of the resulting alkali activated material are discussed. Different type of base materials used in the formation of alkali activated material are blast furnace slag, metakaolin, fly ash, bottom ash, volcanic ashes, and red mud. The state-of-the art in this field demonstrated that this type of materials are ecologically friendly alternative of the Ordinary Portland cement.

An external three component strain gauge balance, designed, analyzed and manufactured in the Military Technical Academy is presented. The balance is a multi-piece type and employs the use of six custom-made load cells (sensors) to transfer the aerodynamic forces and moments from the wing to the computer software environment for data processing and analysis. The relations between the loads acting on the wing model and the measured forces are also underlined. The placement of the strain gauge on the composite laminate is an important issue for increased sensor precision; therefore, it is given a thorough analysis. The positioning of the force vector and its influence on the strain distribution over the lift sensor is also numerically and experimentally analyzed.

The aim of this research was the synthesis of novel 2,3-disubstituted 1,3 thiazolidines, derived from 5-nitroindazole with antimicrobial activity and their encapsulation into polymer nanocapsules. Starting from previously synthesised hydrazones, there have been obtained novel thiazolidines by reaction with thioglycolic acid. The envisaged chemical structures were confirmed by spectral and elemental analysis. Two of the obtained thiazolidines were encapsulated into cationic Eudragit E100 nanocapsules, obtained by nanoprecipitation. In order to enhance drug release characteristics and particle stability, Eudragit E100 nanocapsules were covered with anionic polysaccharide (sodium alginate), thus forming a complex polyelectrolyte based membrane. The obtained nanocapsules presented a slower and more controlled drug release. The synthesized active principles, in free state and encapsulated into polymer nanocapsules, were tested for their acute toxicity and their influence on the development of model bacterial strains (Staphylococcus mutans, Actinobacillus actinomycetemcomitans, Bacillus subtilis, Bacillus cereus, Salmonella enteritidis, Escherichia coli and Staphylococcus aureus).
