Role Of The Antiparallel Double-Stranded Filament Form Of Ftsa In Activating The Escherichia Coli Divisome, Abbigale Perkins, Mwidy Sava Mounange-Badimi, William Margolin

Faculty, Staff and Student Publications

The actin-like FtsA protein is essential for function of the cell division machinery, or divisome, in many bacteria including Escherichia coli. Previous in vitro studies demonstrated that purified wild-type FtsA assembles into closed mini-rings on lipid membranes, but oligomeric variants of FtsA such as FtsAR286W and FtsAG50E can bypass certain divisome defects and form arc and double-stranded (DS) oligomeric states, respectively, which may reflect conversion of an inactive to an active form of FtsA. However, it remains unproven which oligomeric forms of FtsA are responsible for assembling and activating the divisome. Here, we used an in vivo crosslinking assay …

Persistence Of Daptomycin-Resistant And Vancomycin-Resistant Enterococci In Hospitalized Patients With Underlying Malignancies: A 7-Year Follow-Up Study, Lynn El Haddad, Georgios Angelidakis, Yuting Zhai, Layale Yaghi, Cesar A Arias, Samuel A Shelburne, Kwangcheol Casey Jeong, Roy F Chemaly

Faculty, Staff and Student Publications

Vancomycin-resistant enterococci (VRE) commonly colonize the gut of individuals with hematologic malignancies or undergoing hematopoietic cell transplant (HCT) and may cause bacteremia. In 2012, we identified VRE isolates from patients and patients' rooms and showed transmission networks of highly genetically related daptomycin-resistant (DR)-VRE strains. This is a follow-up study performing whole-genome sequencing (WGS) and phylogenetic analyses on 82 clinical VRE strains isolated from stools and blood cultures of patients with leukemia and HCT between 2015 and 2019. Here, we observed transmission of highly genetically related strains between rooms on the same or on different floors, including a DR-VRE strain identified …

Production, Purification, And Specificity Serologically Determination Of Immunoglobulin-Y (Igy) From Chicken Eggs Against Clostridium Tetani Toxoid, Kürşat Teti̇k, Bariş Sareyyüpoğlu

Turkish Journal of Veterinary & Animal Sciences

Tetanus is a life-threatening bacterial disease of humans and many animal species caused by the neurotoxin tetanospasmin (TeNT) produced by Clostridium tetani. Antitoxins obtained from horses and humans are primarily used to treat this disease. However, there are several clinical side effects and disadvantages associated with the use of these antitoxins. Current techniques for diagnosing tetanus use monoclonal antibodies produced in mice. These antibodies have several advantages, such as homogeneity and specificity. In contrast, a notable feature of polyclonal antibodies, especially egg yolk antibodies (IgYs) extracted from poultry, is that they can be generated in greater quantities than mammalian antibodies …

Ligation of the B cell antigen receptor (BCR) initiates humoral immunity. However, BCR signaling without appropriate co-stimulation commits B cells to death rather than to differentiation into immune effector cells. How BCR activation depletes potentially autoreactive B cells while simultaneously primes for receiving rescue and differentiation signals from cognate T lymphocytes remains unknown. Here, we use a mass spectrometry-based proteomic approach to identify cytosolic/nuclear shuttling elements and uncover transcription factor EB (TFEB) as a central BCR-controlled rheostat that drives activation-induced apoptosis, and concurrently promotes the reception of co-stimulatory rescue signals by supporting B cell migration and antigen presentation. CD40 co-stimulation …

UNLABELLED: Human intestinal enteroids (HIEs) are gaining recognition as physiologically relevant models of the intestinal epithelium. While HIEs from adults are used extensively in biomedical research, few studies have used HIEs from infants. Considering the dramatic developmental changes that occur during infancy, it is important to establish models that represent infant intestinal characteristics and physiological responses. We established jejunal HIEs from infant surgical samples and performed comparisons to jejunal HIEs from adults using RNA sequencing (RNA-Seq) and morphologic analyses. We then validated differences in key pathways through functional studies and determined whether these cultures recapitulate known features of the infant …

Development Of A Novel Amplifiable System To Quantify Hydrogen Peroxide In Living Cells, Lingfei Wang, Hanfeng Lin, Bin Yang, Xiqian Jiang, Jianwei Chen, Sandipan Roy Chowdhury, Ninghui Cheng, Paul A Nakata, David M Lonard, Meng C Wang, Jin Wang

Faculty, Staff and Students Publications

Although many redox signaling molecules are present at low concentrations, typically ranging from micromolar to sub-micromolar levels, they often play essential roles in a wide range of biological pathways and disease mechanisms. However, accurately measuring low abundant analytes has been a significant challenge due to the lack of sensitivity and quantitative capability of existing measurement methods. In this study, we introduced a novel chemically induced amplifiable system for quantifying low-abundance redox signaling molecules in living cells. We utilized H2O2 as a proof-of-concept analyte and developed a probe that quantifies cellular peroxide levels by combining the NanoBiT system with androgen receptor …

BACKGROUND: Whereas mechanical thrombectomy (MT) has become standard-of-care treatment for patients with salvageable brain tissue after acute stroke caused by large-vessel occlusions, the results of MT in patients with medium-vessel occlusions (MEVOs), particularly in the posterior cerebral artery (PCA), are not well known.

METHODS: Using data from the international Stroke Thrombectomy and Aneurysm Registry (STAR), we assessed presenting characteristics and clinical outcomes for patients who underwent MT for primary occlusions in the P2 PCA segment. As a subanalysis, we compared the PCA MeVO outcomes with STAR's anterior circulation MeVO outcomes, namely middle cerebral artery (MCA) M2 and M3 segments.

Neuronal Activity In The Gustatory Cortex During Economic Choice, Ahmad Jezzini, Camillo Padoa-Schioppa

2020-Current year OA Pubs

An economic choice entails computing and comparing the values of individual offers. Offer values are represented in the orbitofrontal cortex (OFC)-an area that participates in value comparison-but it is unknown where offer values are computed in the first place. One possibility is that this computation takes place in OFC. Alternatively, offer values might be computed upstream of OFC. For choices between edible goods, a primary candidate is the gustatory region of the anterior insula (gustatory cortex, GC). Here we recorded from the GC of male rhesus monkeys choosing between different juice types. As a population, neurons in GC represented the …

Thinking Long-Term: Nursing Education On Long-Acting Injectable Antipsychotics, Arslan Rashid

DNP Qualifying Manuscripts

Schizophrenia cases and their associated healthcare costs have drastically increased over time in the U.S. Antipsychotic non-adherence is a primary contributor to the high rates of relapse and rehospitalization among the schizophrenic adult population. The development of long-acting injectable antipsychotics (LAIs) has positively impacted medication adherence, however, this treatment modality is still underemployed in practice due to barriers, such as physician and patient negative attitudes toward LAIs and lack of education. Nurses are in a great position to address these barriers as they serve as mediators between providers and patients. This literature review aims to discover evidence that LAI education …

Assessing The Concomitant Presentation Of Acl And Anterolateral Ligament Injuries, Kiang Huang, Katherine Quesada-Tibbetts, Leela Prakash, Neelesh Prakash

Radiology Student Publications

Anterior cruciate ligament (ACL) injuries severely compromise the quality of life in affected patients, so early detection of concurrent injuries is crucial for quicker rehabilitation and proper surgical treatment. Although injuries to the medial meniscus and medial collateral ligament are frequently linked to damage to the ACL, little is known about other important but underappreciated ligament lesions in individuals with ACL injury. The anterolateral ligament (ALL) is a less well-known lesion that presents tearing injuries in 32%-88% of patients with ACL tears in the same knee, with a higher prevalence in complete ACL tears. Despite their lower occurrence, ALL tears …

Commonly Missed Miscellaneous Ligament Injuries Co-Occurring With Acl Tears On Diagnostic Imaging, Katherine Quesada-Tibbetts, Kian Huang, Mafaz Kattih, Albert Brotgandel, Neelesh Prakash

Radiology Student Publications

Anterior cruciate ligament (ACL) injuries greatly affect patient quality of life, necessitating the early identification of additional injuries for faster recovery and appropriate surgical care. Although injuries to the medial meniscus and medial collateral ligament are commonly linked with ACL injuries, there is less awareness of other significant but less recognized ligament lesions in ACL-deficient patients. These less-common injuries include meniscal ramp lesions and meniscal root tears. Research indicates that concomitant ramp lesions are present in 15%-42% of ACL reconstructions, lateral meniscal root tears in 10%-14%, and medial meniscal root tears in a mere 3%. Despite their lower incidence, meniscal …

The Worry Of Food Insecurity And The Manifestation Of Generalized Anxiety In Relation To Perceived Health Status, Ramona Lynnette Taylor

Walden Dissertations and Doctoral Studies

This study examined the association between the worry of food insecurity and the manifestation of generalized anxiety, and how these factors related to perceived health status among adults aged 18 years and older in the U.S. The study controlled demographic factors such as gender, age, race, and education. Utilizing data from the 2019 National Health Interview Survey (NHIS), a binomial logistic regression analysis was employed. The findings indicated a significant association between those persons who often worry about food insecurity, severe (OR = 7.324, p < .001) and frequent generalized anxiety (OR = 5.185, p < .001) suggesting that individuals who worry about food insecurity have higher odds of experiencing severe and frequent (more than 3 times per week) generalized anxiety. Furthermore, both the worry of food insecurity in persons not sure (OR = 0.120, p = 0.004) and generalized anxiety (OR = 0.623 for severe anxiety, p = 0.009) were found to be significantly associated with lower perceived health status. These results suggest a potential association between worry about food insecurity and negative impacts on mental health and perceived overall well-being. Overall, these findings underscore the significant impact of food insecurity on mental health. Further research, including experimental and longitudinal studies, is necessary to elucidate the causal relationship between food insecurity and the manifestation of generalized anxiety in order to impact positive social change.

Personalized cancer vaccines designed to target neoantigens represent a promising new treatment paradigm in oncology. In contrast to classical idiotype vaccines, we hypothesized that "polyvalent" vaccines could be engineered for the personalized treatment of follicular lymphoma (FL) using neoantigen discovery by combined whole-exome sequencing (WES) and RNA sequencing (RNA-seq). Fifty-eight tumor samples from 57 patients with FL underwent WES and RNA-seq. Somatic and B-cell clonotype neoantigens were predicted and filtered to identify high-quality neoantigens. B-cell clonality was determined by the alignment of B-cell receptor (BCR) CDR3 regions from RNA-seq data, grouping at the protein level, and comparison with the BCR …

2020-Current year OA Pubs

Signal peptide (SP) is essential for protein secretion, and pathogenic variants in the SP of factor IX (FIX) have been identified in hemophilia B (HB). However, the underlying mechanism for the genotype-phenotype correlation of these variants has not been well studied. Here, we systematically examined the effects of 13 pathogenic point variants in the SP of FIX using different approaches. Our results showed that these point variants lead to HB by missense variants and/or aberrant premessenger RNA (pre-mRNA) splicing. The missense variants in a hydrophobic core (h-region) mainly affected the cotranslational translocation function of the SP, and those in C-terminal …

Faculty, Staff and Student Publications

It is common knowledge that immunoglobulin (Ig) is produced by B lymphocytes and mainly functions as an antibody. However, it has been shown recently that myeloblasts from acute myeloid leukemia (AML) could also express Ig and that AML-Ig played a role in leukemogenesis and AML progression. The difference between Ig from myeloblasts and B cells has not been explored. Studying the characteristics of the Ig repertoire in myeloblasts and B cells will be helpful to understand the function and significance of AML-Ig. We performed 5' RACE-related PCR coupled with PacBio sequencing to analyze the Ig repertoire in myeloblasts and B …
