Publication Blood Serum-Infrared Spectra-Based Chemometric Models for Auxiliary Diagnosis of Autism Spectrum Disorder(Elsevier, 2021) ILDIZ, GÜLCE ÖĞRÜÇ; Bayarı, Sevgi; Yorguner, Neşe; Fausto, RuiThis chapter focuses on the use of chemometric models developed from infrared (IR) spectroscopic data of blood serum as an auxiliary tool for autism spectrum disorder (ASD) diagnosis. In the introductory sections the fundamentals of IR spectroscopy are shortly reviewed and brief descriptions of the different chemometric methods used in the case study described in the last section of the chapter are presented. The last section deals with the application of the described strategy to the diagnosis of ASD in children and adolescents. © 2021 Elsevier Inc.

Such way of using language in theories of subject object epistemologies is a form of expression of an intentionality the modalities of which are operationally structured with learning and operating with the rules of pictures held fast as standards, rules of criteria of the truth beliefs in identifying what is "true" and "real" in language. Failure of awareness of manifest internal connections of signifying phenomena expressive of intentionality and truth beliefs in connection with the use of pictures and rules of language manifests with its own doxa in the form of attributing or denying essential qualities as to subject object descriptions and as to their interactions, in contrast to an awareness that is capable of tracing back and forth the historical structuring of intentionality operational with pictures and rules of historical languages. The latter only clarifies manifest phenomena expressive of intentionality in internal connections operating and using signs as means and ends without presupposing or introducing entities by means of projecting pictures of language. That clarification works by elucidating the identities and differences attributed to entities in terms of the uses of pictures or signs in internal connection with the uses of other signs the rules of which are kept fast and change by the changing paradigms of cultural-conventional-historical language-games. Here transcendence amounts to the trans-historical dimension of awareness which unknots the knots of operational thinking habits with rules and pictures of historical languages; which are habits that otherwise so chain thinking with the historical intentionality of a historical epoch and systems of beliefs as not to respond and communicate anymore with the self-illuminating light of awareness as characterized by Plato's cave metaphor.Publication Hydantoins and mercaptoimidazoles: Vibrational spectroscopy as a probe of structure and reactivity in different environments, from the isolated molecule to polymorphs(2019) Fausto, Rui; Brás, E.M.; Nogueira, Bernardo A.; ILDIZ, GÜLCE ÖĞRÜÇIn this chapter, we highlight the power of vibrational spectroscopy as central technique to investigate the structure and reactivity of two relevant families of nitrogen-containing heterocyclic molecules: hydantoins and mercaptoimidazoles. Infrared spectroscopy is used in connection with the matrix isolation technique to investigate the structures of the isolated molecules and their photochemistry, while both infrared and Raman spectroscopies, supplemented by thermodynamics, microscopy, and diffraction techniques, are used to investigate neat condensed phases of the compounds and transitions between these phases. The experimental studies are supported by extensive computational studies, which include several approaches for detailed analysis of the electron density.Publication The Importance of Polymers in Medicine and their FTIR and Raman Spectroscopic Investigations(IGI Global, 2023) Çelik, Sefa; AKYÜZ, SEVİM; Özel, Ayşen E.Polymers are macromolecules with a very high molecular weight that are formed as a result of one or more small molecules bonding to each other, typically by covalent bonds. The concept of macromolecules consisting of many repeating units are published in the article titled "Uber Polymerization," which was first published in 1920 by Hermann Staudinger. The idea of polymers, which have been in our lives for a long time, has thus become an important field of study. Polymers are commonly used in tissue engineering because of their properties such as biocompatibility and biodegradability. In addition, polymers have a wide range of applications in tissue regeneration, drug delivery, and wound healing. Polymers have varying structural properties based on their backbone structure, molecular weight, and crystallinity. For this cause, a great deal of study in the medicine has been based on this category of materials. This workfocuses on the importance of polymers in the medicine, 3D printed polymer composites and Fourier transform infrared, and Raman spectroscopic investigations of polymeric structures.
