Comprehensive Overview Of Gastroschisis, Alexis Carver

Mako: NSU Undergraduate Student Journal

Gastroschisis is a congenital defect of the abdominal wall viscera that occurs during early embryonic development, leading to the protrusion of bowel through an opening near the umbilical cord. This condition is classified as either simple, involving only the bowel, or complex, involving additional complications like necrosis or intestinal atresia. While the exact cause of gastroschisis remains unknown, it is believed to be influenced by a combination of genetic and environmental factors. This congenital disorder affects a very small percentage of neonates, and the associated mortality rates are relatively low due to modern developments in medical science. Gastroschisis can be …

Assessment Of Omentin-1 In Diabetic Nephropathy And Insulin Resistance Individuals In Type 2 Diabetic Patients, Nabaa Najam. Abd Zaid Alshamiry, Nibras Hussain. Abdulsada Al-Ghuraibawi

Maaen Journal for Medical Sciences

A case-control study at AL-Sadar Teaching Hospital/Al-Najaf Center found a negative correlation between serum omentin-1 levels and diabetic nephropathy, suggesting early detection of microvascular complications. Long-term diabetes increases the risk of complications, including nephropathy, which worsens over time. High blood pressure is a common comorbidity among diabetics, and careful glycemic control is necessary in advanced stages. Omentin-1 plays a role in enhancing insulin sensitivity and glucose metabolism, but further investigation is needed to determine diabetic nephropathy severity in T2DM patients.

SKMC Student Presentations and Publications

Patients continue to suffer from preventable harm and uneven quality outcomes. Reliable clinical outcomes depend on the quality of robust administrative systems and reliable support processes. Critically ill patient handoffs from the operating room (OR) to the intensive care unit (ICU) are known to be high-risk events. We describe a novel perspective on how risk factors associated with the process of patient handoff communication between the OR and the ICU can lead to flawed communication, degraded team awareness, medical errors, and increased patient harm. Data were collected from two semi-structured focus groups using a five-step risk management approach at a …

Alpha Synuclein And Inflammaging, Geneviève L. Putnam, Robert W. Maitta

Faculty Scholarship

The α-synuclein protein is an established molecule in Lewy body pathology, especially Parkinson's disease (PD). While the pathological role of α-synuclein (α-syn) in PD has been well described, novel evidence may suggest that α-syn interacts with inflammasomes in response to aging. As age is an inevitable physiological state and is also considered the greatest risk factor for PD, this calls for investigation into how α-syn, aging, and PD could be linked. There is a growing amount of data regarding α-syn normal function in the body that includes involvement in cellular transport such as protein complexes assembly, vesicular trafficking, neurotransmitter release, …

Il-1Β In Neoplastic Disease And The Role Of Its Tumor-Derived Form In The Progression And Treatment Of Metastatic Prostate Cancer, Yetunde Oyende, Luke Taus, Alessandro Fatatis

Kimmel Cancer Center Faculty Papers

Since its discovery, IL-1β has taken center stage as a key mediator of a very broad spectrum of diseases revolving around immuno-mediated and inflammatory events. Predictably, the pleiotropic nature of this cytokine in human pathology has led to the development of targeted therapeutics with multiple treatment indications in the clinic. Following the accumulated findings of IL-1β's central modulatory role in the immune system and the implication of inflammatory pathways in cancer, the use of IL-1β antagonists was first proposed and then also pursued for oncology disorders. However, this approach has consistently relied on the perceived need of interfering with IL-1β …

Viruses engage in a variety of processes to subvert host defenses and create an environment amenable to replication. Here, using rotavirus as a prototype, we show that calcium conductance out of the endoplasmic reticulum by the virus encoded ion channel, NSP4, induces intercellular calcium waves that extend beyond the infected cell and contribute to pathogenesis. Viruses that lack the ability to induce this signaling show diminished viral shedding and attenuated disease in a mouse model of rotavirus diarrhea. This implicates nonstructural protein 4 (NSP4) as a virulence factor and provides mechanistic insight into its mode of action. Critically, this …

Transcription elongation, especially RNA polymerase II (Pol II) pause-release, is less studied than transcription initiation in regulating gene expression during meiosis. It is also unclear how transcription elongation interplays with transcription initiation. Here, we show that depletion of NKAPL, a testis-specific protein distantly related to RNA splicing factors, causes male infertility in mice by blocking the meiotic exit and downregulating haploid genes. NKAPL binds to promoter-associated nascent transcripts and co-localizes with DNA-RNA hybrid R-loop structures at GAA-rich loci to enhance R-loop formation and facilitate Pol II pause-release. NKAPL depletion prolongs Pol II pauses and stalls the SOX30/HDAC3 transcription initiation complex …

Cdc25C undergoes a sudden and substantial gel mobility shift at M-phase onset, correlating with abrupt activation of both Cdc25C and Cdk1 activities. A positive feedback loop between Cdk1 and Cdc25C has been used to explain this hallmark phenomenon. Here, we demonstrate that the M-phase supershift and robust activation of Cdc25C are due to the site-comprehensive phosphorylation of its long intrinsically disordered regulatory domain without requiring Cdk1 or other major mitotic kinase activities. The phosphorylation process involves substrate-mediated assembly of phosphorylation machinery that catalyzes multisite phosphorylation continuously without substrate dissociation. In contrast to the site-comprehensive phosphorylation of Cdc25C occurring at M-phase …

Faculty, Staff and Student Publications

The complexity of intestinal cytoarchitecture and function poses significant challenges for the creation of the bioengineered small intestine. Techniques for generating human intestinal organoids (HIOs) resembling human small intestine have been previously reported. HIOs contain epithelium and mesenchyme but lack other critical components of functional intestine such as the enteric nervous system (ENS), immune cells, vasculature, and microbiome. Two independent research groups have published distinct methods to innervate HIOs with an ENS. Here we discuss a unique method of incorporating the ENS into an HIO-derived bioengineered small intestine, which utilizes components of these prior reports to optimize progenitor cell identity …

Speech production engages a distributed network of cortical and subcortical brain regions. The supplementary motor area (SMA) has long been thought to be a key hub in coordinating across these regions to initiate voluntary movements, including speech. We analyzed direct intracranial recordings from 115 patients with epilepsy as they articulated a single word in a subset of trials from a picture-naming task. We aimed to characterize the temporal dynamics of SMA relative to other cortical regions. SMA and preSMA were among the first regions to activate after cue onset, peaked in activity before articulation onset, and were the earliest regions …
