Genital Skin Diseases and Their Expression in Sexual Functionality
Sexual functionality acts as an important function of the individual, acting both physically and mentally to create a state of well-being and permitting procreation. A large number of mucosal and cutaneous ailments may affect the genial areas in both males and females, generally leading to local symptoms that impede the sexual act. Genital diseases, sometimes even without impairing the sexual function, may still alter the dynamics just because of the enormous psychological impact that occurs in these situations. We aim to review main dermatological disorders that alter normal function of the genitalia, as well as their physical mechanism by which the sexual functionality is changed
Eco backstage and its sustainability in terms of design, material or technology
On the website of the European Parliament, it is stated that “the global economy uses the equivalent of one and a half of the planet’s resources in order to produce global results and to absorb waste, and estimates show that these numbers will rise to the level of the resources of two planets by 2030.” Although ecological, sustainability and resilience policies have been adopted through legislation over 60 years ago, humanity finds itself at a point in time when the linear economy and demographic growth are still the main causes for the imminent depletion of natural resources, thus endangering the environment, the planet and the human species itself. In parallel with the implementation of these laws and policies, humanity is also aiming to conquer new territories or to exploit other planets. Although this is a more modern and glamorized mind-set, one that encompasses the whole solar system, it is, in essence, still a primitive “colonizer” thinking pattern. Under these circumstances, sustainable design has become not just a necessity, but rather a sine qua non for survival. Changing the traditional model of the economy to a circular one means multiplying the life cycles of a product. Thus, this paper aims to examine the “greening” of theatre set production by implementing circular design as the primary method to reshape material resources, technology, and product design processes, serving as the sole approach to prevent waste production
Knowledge of SDGs among Students and Determination of their Interest in Building a Career in the Field of Sustainable Development
Sustainable development represents the optimal development option which proposes a harmonization of goals covering economic, social and environmental aspects. The research aims at identifying students' level of knowledge of the concept of sustainable development, of the 17 goals as part of this type of development, and their interest in building a career in the field of sustainable development. The results of the research show that students are familiar with the 17 goals of sustainable development, the main sources of information about sustainable development and SDGs as subjects studied at the University and on the Internet; moreover, many of them want to build a career in the field of sustainable developmen
CH3CH2SCH3+OH radicals: Temperature-dependent rate coefficient and product identification under atmospheric pressure of air
Relative rate coefficients have been determined for the gas-phase reaction of hydroxyl (OH) radicals with ethyl methyl sulfide (EMS) using isobutene as a reference compound. The experiments were performed in a 1080 L quartz glass photoreactor in the temperature range of 286-313 K at a total pressure of 760W10 Torr synthetic air using in situ FTIR absorption spectroscopy to monitor the concentration-time behaviors of reactants and products. OH radicals were produced by the 254nm photolysis of hydrogen peroxide (H2O 2). The kinetic data obtained were used to derive the following Arrhenius expression valid in the temperature range of 286-313 K (in units of cm3 molecule-1 s-1): k = (3.0±0:6) × 10-15 exp [(2457 ± 65)/=T]The rate coefficient displays a negative temperature dependence and low pre-exponential factor which supports the existence of an addition mechanism for the reaction involving reversible OH-adduct formation. The results are compared with previous data of other sulfides from the literature and are rationalized in terms of structure-reactivity relationships. Additionally, product identification of the title reaction was performed for the first time by the FTIR technique under atmospheric conditions. Sulfur dioxide, formaldehyde, and formic acid were observed as degradation products in agreement with the two possible reaction channels (addition/abstraction).

Is Homocysteine a Marker or a Risk Factor: A Question Still Waits for an Answer
Homocysteine, a non-proteinogenic sulfur-containing amino acid, was discovered in 1932, and 30 years passed until, in 1969, for the first time, its involvement in pathology was reported. It was only in the last two decades that homocysteine has become a subject of scientific interest and has begun to be intensively studied. A large number of scientists consider homocysteine as an independent risk factor particularly for cardiovascular disease, while others indicate homocysteine as a marker of this disease. Both sides bring scientific arguments for their opinions, yet the dilemma of homocysteine characterization still persists. Although the reported studies do not lead to a unique answer, it is generally accepted that homocysteine is associated with vascular dysfunction. Numerous scientific data show that the link between homocysteine and inflammation is achieved via the reactive oxygen species (ROS) pathway. The latest data indicate hydrogen peroxide as a possible messenger in cellular signaling in physiological or pathological processes and present the consequences of disturbing the oxidation-reducing balance. In this chapter, we present the latest scientific evidences gathered from the literature for both hypotheses regarding homocysteine involvement in pathology, and we propose a possible mechanism of action for homocysteine, based on our preliminary (yet unpublished) work
