Chapter 5 examines the dynamic nature of interfaces and starts examining their characteristics. The authors posit that just as we might derive a multitude of dimensions to describe biological structure, so too are there many dimensions that describe the functional dynamics in how biological systems vary over time. Current environmental epidemiological methods used in analyzing data on our environment and our physiology treat each measure as if it were an independent dimension, much like a carpenter measuring the height, width, or length of a piece of furniture. However, because there are processes underlying our physiological development, constraints are applied to the forms that we and our environment can take. Knowledge of these can be harnessed to identify the primary dimensions along which we must characterize the systems under study. By doing this we were able to take an important first step in operationalizing Environmental Biodynamics for clinical application.

Coronavirus disease 2019 (COVID-19) pandemic is a serious threat to global public health and social and economic development. Various vaccine platforms have been developed rapidly and unprecedentedly, and at least 16 vaccines receive emergency use authorization (EUA). However, the causative pathogen severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has continued to evolve and mutate, emerging lots of viral variants. Several variants have successfully become the predominant strains and spread all over the world because of their ability to evade the pre-existing immunity obtained after previous infections with prototype strain or immunizations. Here, we summarized the prevalence and biological structure of these variants and the efficacy of currently used vaccines against the SARS-CoV-2 variants to provide guidance on how to design vaccines more rationally against the variants.

Objective D-dimer, ferritin, and fibrinogen parameters in COVID-19 patients are essential, particularly in inpatients and intensive care unit patients. It is vital to know the changes that occur due to the biological structure of the person than the disease effect in these tests to manage the fatal disease better. Method Blood samples were taken on the first, third, and fifth days from 30 healthy volunteers, 15 of whom were smokers, 15 were non-smokers, and D-dimer, ferritin, and fibrinogen tests were studied with repeated measurements. After the data was processed for normality and homogeneity and removing extreme values, CVA, CVI, CVG, CVT, RCV, II, I%, B%, TE% values were calculated via a complete nested ANOVA design, according to Callum G, Fraser, and EFLM. Results CVI and CVG values of D-dimer were calculated as 49.07% and 40.69% for all individuals, 49.26% and 27.71% for smokers, 48.80% and 51.67% for non-smokers, respectively. In terms of fibrinogen, the same analyzes for all individuals were calculated as 11.18% and 10.62%, 3.25% and 20.17% for smokers, 9.11% and 6.79% for non-smokers, respectively. The same ferritin analyses were calculated as 23.74% and 63.31% for all individuals, 34.98% and 35.24% for smokers, 30.53% and 74.87% for non-smokers, respectively. Conclusion Changes in D-dimer measurements every other day in healthy individuals can be observed depending on the biological characteristics of the individuals, and the population-based reference interval may be insufficient for clinical evaluation. Therefore, each individual should be evaluated within themselves. When assessing the results of ferritin and fibrinogen in non-smoking individuals, it should be taken into account that significant differences may occur between individuals. Besides, it should be kept in mind that there may be considerable changes due to biological variation in the repeated measurements of ferritin every other day.

Topological descriptors are mathematical values related to chemical structures which are associated with different physicochemical properties. The use of topological descriptors has a great contribution in the field of quantitative structure-property relationship (QSPR) and quantitative structure-activity relationship (QSAR) modeling. These are mathematical relationships between different molecular properties or biological activity and some other physicochemical or structural properties. In this article, we calculate few vertex degree-based topological indices/descriptors of the organometallic monolayer structure. At present, the numerical programming of the biological structure with topological descriptors is increasing in consequence in invigorating science, bioinformatics, and pharmaceutics.

AbstractSuper-resolution localization microscopy allows visualization of biological structure at nanoscale resolution. However, the presence of heterogeneous background can degrade the nanoscale resolution by tens of nanometers and introduce significant image artifacts. Here we investigate and validate an efficient approach, referred to as extreme value-based emitter recovery (EVER), to accurately recover the distorted fluorescent emitters from heterogeneous background. Through numerical simulation and biological experiments, we validated the accuracy of EVER in improving the fidelity of the reconstructed super-resolution image for a wide variety of imaging characteristics. EVER requires no manual adjustment of parameters and has been implemented as an easy-to-use ImageJ plugin that can immediately enhance the quality of reconstructed super-resolution images. This method is validated as an efficient way for robust nanoscale imaging of samples with heterogeneous background fluorescence, such as thicker tissue and cells.


Bioremediation uses microorganisms to destroy or immobilize waste materials. Microorganisms include archaea, bacteria, fungi and actinomycetes. Microorganisms destroy organic contaminants when they are using chemicals for their growth and reproduction. Although it is an old technique, it is still frequently used to remove environmental contaminants which have increased rapidly due to increased population, industrialization, and urbanization. There are various types of bioremediation, and different mechanisms associated with them. The process of bioremediation is enhanced by biostimulation. When bacterial culture is added to the contaminants to increase the rate of biodegradation, it is known as bio augmentation. Biosensors are devices used to detect the presence or concentration of a biological analyse, such as a biomolecule, a biological structure or a microorganism. This paper gives an idea of bioremediation, its scope, factors affecting bioremediation, types, biostimulation, bioaugmentation and biosensors.

The traditional examples that continue and develop the process in Anatolian weaving are numerous for those who know how to make use of it. In 2013, during the archaeological excavations at Çatalhöyük, it was discovered in the BC. 7000 parts of linen weaving dated to were found. Due to its biological structure, humans have benefited from weaving to protect themselves from adverse weather conditions and to spend their lives more comfortably. Weavings created for natural needs are coloured to influence other people in the society and decorated with various methods. Ornamental elements start with a dot, continue with a line, and finish with colour. Weavings vary according to the cultural values conditions of the society and geographical position. Anatolian people used the line and the motifs they made by making use of the line in the decoration of their weavings. Line is a means of expression that has been used from the earliest periods of human history to the present day. One of the most important values in the cultural, artistic and sociological life of a person is the line. They have visualized pictures of weaving, which is considered a sacred profession, on many surfaces. Line has always been used as a basic element in traditional Anatolian weavings. Weavers transferred the different uses of the line to their weavings. With the arrival of the Yörüks and Turkmens from the Oghuz tribes to Anatolia, Anatolia was enriched with nomadic society weavings. There are linear elements on the basis of ornamentation of nomadic Turkish weavings. Yörük and Turkmen weavers who settled in Anatolia continued the weaving process in Anatolia until recently. In weaving patterns, they generally used line and line-based motifs. In this study; information will be given about line, iconography of line and textural surfaces created by line in Anatolian traditional weavings. Keywords: Anatolian, Weaving, Line, Iconography, Traditional.

Humans with male and female types should be seen by referring to their competence and skill capabilities, not their biological personality. Human biological structure is natural. If humans are still questioning this difference which then leads to the inequality of public social roles between one of these types, then it can be said that he is part of the patriarchal missionary. That's why there must be one among us who dares to voice and realize that the creation of the two types of humans has an implicit divine message, namely sharing roles.
