The Boyland-Sims Oxidation reaction uses an alkaline solution of peroxydisulfate salt to convert arylamines to o-aminophenols. The long-standing mechanism involves a nucleophilic attack by the amine leading to the formation of an arylhydroxylamine-O-sulfonate intermediate, which then rearranges to the arylamine o-sulfate. The long-standing mechanism of a nucleophilic attack by the amine on peroxide oxygen has been questioned by Marjanović et al. who have proposed a nitrenium ion intermediate as the reactive species rather than the uncharged amine. It has been challenged by a variety of experimental observations. We present here new computations at a high-level of density functional theory (B3LYP/6-311++G**) to model both arylhydroxylamine-O-sulfonate and nitrenium ion pathways in a series of aromatic amines. In this study, the energetics of reaction intermediates in both mechanisms are computed for aniline, 2,4-dinitroaniline, and N,N-dimethylaniline. To further support the pathways of the reaction, the calculations were performed to find the transition states involved in both mechanisms. The transition state calculations revealed two possible energetically feasible pathways for the rearrangement of arylhydroxylamine-O-sulfonate to arylamine o-sulfate. Our results indicate that the Boyland-Sims oxidation reactions proceed via arylhydroxylamine-O-sulfonate intermediate as predicted earlier.
Boyland-Sims氧化反应使用过硫酸氢盐的碱性溶液将芳胺转化为邻氨基酚。长期存在的机制涉及胺的亲核攻击,导致形成芳基羟胺-邻磺酸盐中间体,然后重新排列成芳基胺-邻硫酸酯。marjanoviki等人对胺对过氧的亲核攻击的长期机制提出了质疑,他们提出了一种氮离子中间体而不是不带电的胺作为反应物质。它受到了各种实验观察的挑战。在这里,我们提出了一个新的计算方法,在高密度泛函理论(B3LYP/6-311++G**)的高层次上模拟芳基羟胺-邻磺酸盐和氮离子在一系列芳香胺中的途径。本研究计算了苯胺、2,4-二硝基苯胺和N,N-二甲基苯胺两种反应机制中中间体的能量学。为了进一步支持反应的途径,进行了计算,以找到两种机制中涉及的过渡态。过渡态计算揭示了芳基羟胺-邻磺酸盐重排至邻硫酸芳胺的两种可能的能量可行途径。我们的结果表明,Boyland-Sims氧化反应通过芳基羟胺- o -磺酸盐中间体进行,正如之前预测的那样。

Maternal hyperthyroidism effects development in infants and can lead to conditions such as craniosynostosis, exophthalmos, and cardiac hypertrophy. Models for studying maternal hyperthyroidism, or thyrotoxicosis, are limited. Our lab has established an avian model to study the effects of induced thyrotoxicosis on embryonic development. Thyroid hormones (TH) cause inotropic and chronotropic changes in cardiac tissue, including increased cardiac output, increased blood volume, and hypertrophy. Therefore, we wanted to investigate the cardiac changes in our model. Fertilized chicken eggs are injected on embryonic days (E) 11 and 15 with either saline (control) or 25ng thyroxine (T4). Hearts were harvested on day E19, with halves of each sample used for histological staining with Masson’s Trichrome and qRT-PCR analysis. The main objective was to observe systemic effects of our model by studying morphological and genetic changes in the heart following exposure by measuring expression of THRa (TR receptor), ATP2A2 (calcium ATPases), and MYH7(Myosin heavy chain 7). We hypothesized that levels of all 3 markers would be upregulated, since THRaregulates transcription of these other cardiac markers due to fluctuating levels of TH. These are linked to ventricular hypertrophy when upregulated. However, our results contradicted our hypothesis. There was downregulation of all 3 genes, with a significant downregulation in ATP2A2. In combination with other data collected in our lab and related literature, we suspect that there is a cardiac protective effect occurring in the hearts following thyroxine exposure.

Decomposition of organic tissue is a complex process that is affected by a large number of interactions. These variables affect the rate of decomposition, insect activity, and the onset of each individual stage in the decomposition process. Of the variables in effect, some of the most commonly studied are temperature and moisture. The purpose of this study is to analyze the impact of other variables, such as age at death, body size, sun exposure, and presence of preservation chemicals on the rate of decomposition in nonhuman specimens. The goal of this research is to give more insight into the complex interactions between these variables and analyze the reliability of current decomposition analysis. As ethical considerations and policies affect how researchers use human remains, more decomposition research is needed to better understand this very sensitive process and all the variables that are included. Preliminary results suggest that sun exposure, relative body size, and age at death do not significantly affect the rate of nonhuman decomposition, but a principal component analysis suggests correlation does exist between subsets of these variables. Ongoing work to include larger sample sizes, as well as chemically preserved animals, is currently running. Expected results indicate that preserved animals will take longer to fully decompose, and the effects of age, sun exposure, and body size will not be significant.

The objectives of this experiment looked at were that the DNA, both skin cells and saliva, have the potential of binding with the superglue as it coats each object being fumed. If DNA has the potential of binding with the superglue, then it is very possible for DNA to be carried in the air by the humidifier, thus contaminating other objects. For the first experiment, two saliva covered microscope slides, one female and one male, were fumed along with 25 other sterile slides. Each sterile slide was swabbed and analyzed for DNA in an electrophoresis gel chamber. The second experiment fumed ten microscope slides presented with fingerprints. Each sterile slide was swabbed and analyzed for DNA in an electrophoresis gel chamber. The results showed that there was minimal cross contamination present on the slides fumed with the saliva based slides. The touch DNA experiment showed that there are potentially identifiable DNA markers present in fingerprints after fuming. The results concluded that it is possible to have DNA cross contamination between items that carry no DNA prior to the fumigation, and potential DNA can be found on fingerprints after fumigation.

The somatosensory and visual systems adaptation times have a strong positive correlation. Multiple studies demonstrated that all sensory systems adapt their sensitivity levels to improve their responsiveness to changes in corresponding stimulation and to accelerate following CNS processing. The study aimed to determine if the time of adaptation observed for the somatosensory system correlates with the adaptation time observed for the visual system. The data collection was performed on 2 male and 7 female healthy volunteers (the average age of those was 22.2+/-4.60, 8 right-handed and 1 left-handed) in a seated position. The adaptation time for the somatosensory system was estimated by recording the time of the perception loss after placing a 1 penny coin onto the dorsal hand surface. To evaluate the adaptation time for the visual system the subject was asked to stare at a small pastel color abstract image. The time of the perceived loss for the component of this image was recorded. The average adaptation time for somatosensory perception was 22.0+/-16.15 seconds ranging from 4 to 42 seconds. The average adaptation time for visual perception was 30.7+/-16.04 seconds ranging from 12 to 51 seconds. There was a statistically significant difference between the adaptation time for these modalities of the sensations as determined by paired T-test (t (8) = 3.1, p = .01). However, the correlation analysis demonstrated a strong positive correlation between values (r (8) = 0.86, p = .003). Our data indicate that the times of somatosensory and visual adaptation are strongly correlated. The finding of this study can be used for the development and improvement of neurobehavioral evaluation tests.

It is everyday practice to utilize aseptic techniques, which are simply actions taken to prevent the accumulation of bacteria and other microbes to prevent diseases and their spread. Handwashing is an important aspect of hand hygiene because hands pick up the microbes from surfaces and are easily transported from person to person through direct contact or indirect contact. According to the CDC and WHO, many diseases are spread by not washing hands effectively, therefore hand hygiene is important everywhere in society, especially in healthcare where the spread of disease can mean life or death. In this study, we analyzed data collected from the student population of microbiology classesfrom the University of Charleston in West Virginia over the span of nine years (2014 to present). We measured the number of colony forming units (CFU) from students’ hands prior to manipulation (control), using just water, using soap and water, and using hand sanitizer. We hypothesized that handwashing and use of antimicrobial aids such as hand sanitizer will reduce the number of bacteria on hands compared to controls. An analysis was also performed comparing pre-pandemic and post-pandemic data to determine if handwashing behaviors have changed behavior which would alter the normal microfauna on the hands. This analysis revealed that there was a significant difference between handwashing techniques (p<0.001). There was a difference in formation of colony forming units between pre and post pandemic times (p<0.001).

In Southeastern Kentucky a small, cold stream-dwelling crayfish, Cambarus jezerinaci, located in the Kentucky and Cumberland River basin may be a part of a species complex. A previous study done in 2008 on the cytochrome oxidase 1 gene (CO1) of C. jezerinaci and Cambarus parvoculus, a sister species in the region, identified a third genetically distinct lineage most similar to C. jezerinaci currently retained as Group B C. jezerinaci. Group B is as different from the true species as the true species is to C. parvoculus, a total CO1 difference greater than 5%. Morphological characteristics were also compared between C. jezerinaci and C. parvoculus with only rostral states being significant to species identification. However, in light of new genetic lineages previous research suggested the separation of them before morphological comparisons. In 2022 and 2023 research was conducted on both the genetics and morphological differences of C. jezerinaci within two river basins to better understand the taxonomic standing of this crayfish. Determining the true status of C. jezerinaci within these two river basins is important to the conservation of these animals. Continuing genetic research helps us to grow our understanding of what it means to be a species in the modern age and also allows us to learn about the biodiversity and speciation process itself. Given the rapidly changing climate, it is imperative to catalog the true diversity of our freshwater streams and develop conservation action plans for endemic species such as C. jezerinaci.

The objective of this study was to provide a new method for creating quantum-proof encryption algorithms. I accomplished this by designing a symmetric 2-key cryptosystem that exploits the superposition principle to encrypt data in multi-dimensional value spaces. The proposed cryptosystem substitutes characters for frequencies, as determined by two private keys: component wave order key (CWOK) and character transmission order key (CTOK). A CWOK defines the values and theoretical spatial arrangement of frequencies in a complex wave. A CTOK defines the unique arrangement of system characters (i.e., characters in an encoding scheme such as ASCII), determined by a hash function, to identify a user. Combining the CWOK and CTOK, we construct a character-lookup table (CLT), which defines the character-frequency relationships used to generate a substitution cipher. A cipher’s frequency values must be superimposed in accordance with the CWOK. Fast Fourier Transforms are used during the decryption stage to perform complex wave analysis. Complex waves can have n! frequency configurations, where n = the number of component frequencies; each CTOK can have a! character configurations, where a = the number of characters defined in an encoding scheme. Therefore, by requiring n ≥128 and using the ASCII encoding scheme (a = 128), there are n!+a!=128!+128!=2*128! possible key configurations for any given cipher. This is approximately 3.330284e+138 times as many key configurations possible with AES 256. Exploiting the multi-dimensional nature of complex waves, and combining these techniques with other powerful encryption algorithms used today, it appears likely that we can create a quantum-proof cryptosystem.

Many species of bacteria, under conditions of stress or nutrient limitation, enter a state of dormancy referred to as viable but non-culturable (VBNC). VBNC bacteria persist in the environment, are difficult to detect and identify by many standard laboratory methods and can be altered in their susceptibility to antibiotics. Entry into the VBNC state is often accompanied by morphological changes; however, the mechanisms underlying this are poorly understood. Francisella transitions rapidly and spontaneously to a VBNC state, and therefore has the potential to be an excellent model organism for the study of this phenomenon. To investigate the transcriptome of VBNC F. tularensis LVS we extracted RNA from culturable and VBNC cells and carried out an RNA-Seq analysis using both Long-read Nanopore and Illumina Sequencing. Differentially expressed genes (DEGs) were identified using a DE-Seq pipeline. Over 300 genes were significantly upregulated and ~100 genes were down regulated in VBNC cells. Amongst the upregulated genes were some involved in the transport of metals or small molecules, and we have also identified putative transcriptional regulators that may be master controllers of the VBNC process. Our data represents the first transcriptomic analysis of F. tularensis LVS as it transitions into the VBNC state. Identifying genes that are involved in this transition is a critical first step in understanding the mechanisms that drive F. tularensis LVS into the VBNC state and will help us identify factors that allow the resuscitation of these bacteria. This will have important implications for understanding both environmental persistence and pathogenicity of Francisella species.

许多种类的细菌,在应激或营养限制的条件下,进入一种休眠状态,称为可活但不可培养(VBNC)。VBNC细菌在环境中持续存在,难以通过许多标准实验室方法检测和鉴定,并且可以改变其对抗生素的敏感性。进入VBNC状态往往伴随着形态变化;然而,人们对其背后的机制知之甚少。Francisella可以快速自发地过渡到VBNC状态,因此有可能成为研究这一现象的优秀模式生物。为了研究VBNC F. tularensis LVS的转录组,我们从可培养细胞和VBNC细胞中提取RNA,并使用长读纳米孔和Illumina测序技术进行RNA- seq分析。使用DE-Seq管道鉴定差异表达基因(DEGs)。在VBNC细胞中,超过300个基因显著上调,约100个基因显著下调。在上调的基因中,有一些涉及金属或小分子的运输,我们还确定了可能是VBNC过程主控者的转录调控因子。我们的数据代表了土拉菌LVS转变为VBNC状态时的首次转录组学分析。识别参与这种转变的基因是理解驱动土拉菌LVS进入VBNC状态的机制的关键的第一步,并将帮助我们确定允许这些细菌复苏的因素。这将对了解弗朗西斯菌的环境持久性和致病性具有重要意义。(NIH拨款P20GM103434资助西弗吉尼亚IDeA网络生物医学卓越研究)
