CPAP Effect in Patients with Hypertension: The Secret of Gods

Obstructive sleep apnea syndrome (OSAS) is a respiratory sleep disorder characterized by episodes of occlusion of the upper respiratory tract, resulting in intermittent chronic hypoxia and sleep fragmentation. Clinical studies have described an association between OSAS and arterial hypertension (SAH), with CPAP being the treatment of choice. The use of CPAP in the treatment of OSAS makes it possible to avoid blocking the passage of air to the lungs. The primary underlying mechanism of hypertension in individuals with OSAS is the activation of the sympathetic nervous system triggered by episodes of apnea. Currently, there are no studies that correlate the use of CPAP and the decrease in the use of antihypertensive agents in patients with OSAS.

Hemoglobin SC Disease with COVID-19 Presenting with Multiple Infarcts and Acute Splenic Sequestration Crises

Hb SC disease is a type of hemoglobinopathy that can be viewed as a hybrid of hemoglobin S and C. In this disorder there is co-inheritance of one Hbs gene and one HbC gene resulting in a milder phenotype than sickle cell anemia (SCA). Whereas SCA clinical features have been extensively studied, very few studies have been dedicated specifically to HbSC disease as most cases are reported to be silent or of mild severity. As the pandemic continues to evolve with the novel Sars-CoV-2 virus we have learned it can lead to thrombotic complications which could be fatal if not detected early. Of those requiring admission to the intensive care unit, most carry multiple comorbidities (hypertension, diabetes mellitus etc.) leading to worse clinical outcomes. Here, we present a case of a young adult patient with silent hemoglobin SC disease who tested positive for SARS-CoV-2 leading to multiple infarcts, splenic sequestration and respiratory failure. The concurrence of a hemoglobinopathy and COVID-19 should warrant heightened clinical suspicion for unusual outcomes. Hence, providers must remain vigilant while treating any patient with any hemoglobinopathy in the setting of COVID-19.

Low RNA Binding Strength of Human X Chromosome may contribute to X Chromosome Inactivation

During early embryonic development in female mammals, one copy of the X chromosome is randomly inactivated in a process known as X chromosome inactivation. In X chromosome inactivation, approximately 70% of genes on the short arm and nearly all of the genes on the long arm of the designated chromosome are inactivated. RNA activation is known to RNAs activating gene expression; however its roles in X chromosome inactivation have not been determined.

A Data-Based Adjustment for Fisher Exact Test

Fisher exact test is one of most popularly used methods in modern data analyses. However, it is conservative because of discreteness. The mid-p method may reduce the conservativeness but it is defined by the factor 1/2, an extra term beyond data. This paper considers an adjustment defined by a data-based factor. The adjusted test is compared with other ten tests. Special attention is given to the comparison between the data-based factor and the factor 1/2. The standardized version of the adjusted test is asymptotically standard normal.

Anodizing for Design and Function

Two basic reactions occur during the anodizing of aluminum: 1) the aluminum is consumed and 2) an oxide grows. By accepting this statement as true, the anodizing process can be viewed as a corrosion process, and anodizing can be modeled using the Tafel Equation. Anodizing process parameters of electrolyte chemistry and concentration, temperature, aluminum substrate resistance and current density are presented as they relate to the Tafel Equation and how they impact the anodic aluminum oxide structure and properties. Understanding this relationship is consequent in making anodizing an engineering process, one that enables tuning the structure such that it yields distinct characteristics to fulfill design and application requirements.

Electronic-nose Applications in Forensic Science and for Analysis of Volatile Biomarkers in the Human Breath

The application of electronic-nose (E-nose) technologies in forensic science is a recent new development following a long history of progress in the development of diverse applications in the related biomedical and pharmaceutical fields. Data from forensic analyses must satisfy the needs and requirements of both the scientific and legal communities. The type of data collected from electronic-nose devices provides a means of identifying specific types of information about the chemical nature of evidentiary objects and samples under investigation using aroma signature profiles of complex gaseous mixtures containing volatile organic compounds (VOCs) released from manufactured products and parts of the human body. E-nose analyses also provide useful qualitative information about the physicochemical characteristics and metabolic conditions of human subjects without the need for time-consuming analyses to identify all chemical components in human-derived volatile mixtures.
