Domestic Minor Sex Trafficking: The Challenges Faced In Prosecuting Those Who Prey On America’S Youth, Sherri Zack

Journal of Applied Research on Children: Informing Policy for Children at Risk

This commentary is a discussion of the article "Human Trafficking, Sex Tourism, and Child Exploitation on the Southern Border." Most importantly, it is a comment on the lack of attention given to American children prostituted in our own backyards. All forms of sex trafficking are deplorable but the plight of the American child victim creates unique challenges for prosecutors, law enforcement and non-governmental agencies working hard to bring the crimes involved with domestic minor sex trafficking to the forefront. To that end, this commentary attempts to provide resources and guidance.

Learning Curve For Robotic-Assisted Laparoscopic Colorectal Surgery, Malak B Bokhari, Chirag B Patel, Diego I Ramos-Valadez, Madhu Ragupathi, Eric M Haas

Faculty, Staff and Student Publications

BACKGROUND: Robotic-assisted laparoscopic surgery (RALS) is evolving as an important surgical approach in the field of colorectal surgery. We aimed to evaluate the learning curve for RALS procedures involving resections of the rectum and rectosigmoid.

METHODS: A series of 50 consecutive RALS procedures were performed between August 2008 and September 2009. Data were entered into a retrospective database and later abstracted for analysis. The surgical procedures included abdominoperineal resection (APR), anterior rectosigmoidectomy (AR), low anterior resection (LAR), and rectopexy (RP). Demographic data and intraoperative parameters including docking time (DT), surgeon console time (SCT), and total operative time (OT) were analyzed. …

Progenitor Cells As Remote "Bioreactors": Neuroprotection Via Modulation Of The Systemic Inflammatory Response, Peter A Walker, Phillip A Letourneau, Supinder Bedi, Shinil K Shah, Fernando Jimenez, Charles S Cox Jr

Faculty, Staff and Student Publications

Acute central nervous system (CNS) injuries such as spinal cord injury, traumatic brain injury, autoimmune encephalomyelitis, and ischemic stroke are associated with significant morbidity, mortality, and health care costs worldwide. Preliminary research has shown potential neuroprotection associated with adult tissue derived stem/progenitor cell based therapies. While initial research indicated that engraftment and transdifferentiation into neural cells could explain the observed benefit, the exact mechanism remains controversial. A second hypothesis details localized stem/progenitor cell engraftment with alteration of the loco-regional milieu; however, the limited rate of cell engraftment makes this theory less likely. There is a growing amount of preclinical data …

Molecular Mechanism By Which The Nucleoid Occlusion Factor, Slma, Keeps Cytokinesis In Check, Nam Ky Tonthat, Stefan T Arold, Brian F Pickering, Michael W Van Dyke, Shoudan Liang, Yue Lu, Tushar K Beuria, William Margolin, Maria A Schumacher

Faculty, Staff and Student Publications

In Escherichia coli, cytokinesis is orchestrated by FtsZ, which forms a Z-ring to drive septation. Spatial and temporal control of Z-ring formation is achieved by the Min and nucleoid occlusion (NO) systems. Unlike the well-studied Min system, less is known about the anti-DNA guillotining NO process. Here, we describe studies addressing the molecular mechanism of SlmA (synthetic lethal with a defective Min system)-mediated NO. SlmA contains a TetR-like DNA-binding fold, and chromatin immunoprecipitation analyses show that SlmA-binding sites are dispersed on the chromosome except the Ter region, which segregates immediately before septation. SlmA binds DNA and FtsZ simultaneously, and the …

Hypertensive Nephropathy Treatment By Heart-Protecting Musk Pill: A Study Of Anti-Inflammatory Therapy For Target Organ Damage Of Hypertension, Dengke Tian, Shuang Ling, Gangling Chen, Yajuan Li, Jun Liu, Murad Ferid, Ka Bian

Faculty, Staff and Student Publications

This study was designed to investigate the protective effect of the heart-protecting musk pill (HMP) on inflammatory injury of kidney from spontaneously hypertensive rat (SHR). Male SHRs aged 4 weeks were divided into SHR model group, HMP low-dosage group (13.5 mg/kg), and HMP high-dosage group (40 mg/kg). Age-matched Wistar-Kyoto rats were used as normal control. All rats were killed at 12 weeks of age. Tail-cuff method and enzyme-linked immunosorbent assay were used to determine rat systolic blood pressure and angiotensin II (Ang II) contents, respectively. Renal inflammatory damage was evaluated by the following parameters: protein expressions of inflammatory cytokines, carbonyl …

Spinal Cord Protection: Lessons Learned From Endovascular Repair, Jennifer N Dulin, Meredith L Moore, Kevin W Gates, Joanna H Queen, Raymond J Grill

Faculty, Staff and Student Publications

There is a high incidence of infertility in males following traumatic spinal cord injury (SCI). Quality of semen is frequently poor in these patients, but the pathophysiological mechanism(s) causing this are not known. Blood-testis barrier (BTB) integrity following SCI has not previously been examined. The objective of this study was to characterize the effects of spinal contusion injury on the BTB in the rat. 63 adult, male Sprague Dawley rats received SCI (n = 28), laminectomy only (n = 7) or served as uninjured, age-matched controls (n = 28). Using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), BTB permeability to the …

The Hypoxia-Adenosine Link During Myocardial Ischemia—Reperfusion Injury, Diana Panesso, Maria C Montealegre, Sandra Rincón, Maria F Mojica, Louis B Rice, Kavindra V Singh, Barbara E Murray, Cesar A Arias

Faculty, Staff and Student Publications

BACKGROUND: Plasmids containing hylEfm (pHylEfm) were previously shown to increase gastrointestinal colonization and lethality of Enterococcus faecium in experimental peritonitis. The hylEfm gene, predicting a glycosyl hydrolase, has been considered as a virulence determinant of hospital-associated E. faecium, although its direct contribution to virulence has not been investigated. Here, we constructed mutants of the hylEfm-region and we evaluated their effect on virulence using a murine peritonitis model.

RESULTS: Five mutants of the hylEfm-region of pHylEfmTX16 from the sequenced endocarditis strain (TX16 [DO]) were obtained using an adaptation of the PheS* system and were evaluated in a commensal strain TX1330RF to …

BACKGROUND: We have carried out an extensive qualitative research program focused on the barriers and facilitators to successful adoption and use of various features of advanced, state-of-the-art electronic health records (EHRs) within large, academic, teaching facilities with long-standing EHR research and development programs. We have recently begun investigating smaller, community hospitals and out-patient clinics that rely on commercially-available EHRs. We sought to assess whether the current generation of commercially-available EHRs are capable of providing the clinical knowledge management features, functions, tools, and techniques required to deliver and maintain the clinical decision support (CDS) interventions required to support the recently defined …

Complete Genome Sequence Of Treponema Paraluiscuniculi, Strain Cuniculi A: The Loss Of Infectivity To Humans Is Associated With Genome Decay, David Smajs, Marie Zobaníková, Michal Strouhal, Darina Cejková, Shannon Dugan-Rocha, Petra Pospíšilová, Steven J Norris, Tom Albert, Xiang Qin, Kym Hallsworth-Pepin, Christian Buhay, Donna M Muzny, Lei Chen, Richard A Gibbs, George M Weinstock

Faculty, Staff and Student Publications

Treponema paraluiscuniculi is the causative agent of rabbit venereal spirochetosis. It is not infectious to humans, although its genome structure is very closely related to other pathogenic Treponema species including Treponema pallidum subspecies pallidum, the etiological agent of syphilis. In this study, the genome sequence of Treponema paraluiscuniculi, strain Cuniculi A, was determined by a combination of several high-throughput sequencing strategies. Whereas the overall size (1,133,390 bp), arrangement, and gene content of the Cuniculi A genome closely resembled those of the T. pallidum genome, the T. paraluiscuniculi genome contained a markedly higher number of pseudogenes and gene fragments (51). In …

Alterations In Content And Localization Of Defensins In Rat Ileum And Jejunum Following Ischemia-Reperfusion Specific Peptides, In Specific Places, For Specific Jobs?, Rosemary A Kozar, Rachel J Santora, Brian J Poindexter, Stephen M Milner, Roger J Bick

Faculty, Staff and Student Publications

Objective: To determine alterations in quantities and distributions of natural antimicrobials following ischemia-reperfusion injury. We hypothesized that these compounds would be upregulated in areas of small intestine where changes in permeability and cellular disruption were likely and where protective mechanisms would be initiated. Methods: Rats with ischemia-reperfusion underwent superior mesenteric artery clamping and reperfusion. Shams were subjected to laparotomy but no clamping. Ileum and jejunum were harvested and sectioned, and subjected to fluorescence deconvolution microscopy for determinations of content and localization of rat beta defensins, 1, 2, 3; rat neutrophil protein-1; and cathelicidin LL-37. Modeling was performed to determine cellular …

Association Of Retinoic Acid Receptor Genes With Meningomyelocele, Phong X Tran, Kit Sing Au, Alanna C Morrison, Jack M Fletcher, Kathryn K Ostermaier, Gayle H Tyerman, Hope Northrup

Faculty, Staff and Student Publications

BACKGROUND: Neural tube defects (NTDs) occur in as many as 0.5-2 per 1000 live births in the United States. One of the most common and severe neural tube defects is meningomyelocele (MM) resulting from failed closure of the caudal end of the neural tube. MM has been induced by retinoic acid teratogenicity in rodent models. We hypothesized that genetic variants influencing retinoic acid (RA) induction via retinoic acid receptors (RARs) may be associated with risk for MM.

METHODS: We analyzed 47 single nucleotide polymorphisms (SNPs) that span across the three retinoic acid receptor genes using the SNPlex genotyping platform. Our …

Immunopathology Of Postprimary Tuberculosis: Increased T-Regulatory Cells And Dec-205-Positive Foamy Macrophages In Cavitary Lesions, Kerry J Welsh, Semyon A Risin, Jeffrey K Actor, Robert L Hunter

Faculty, Staff and Student Publications

Postprimary tuberculosis occurs in immunocompetent people infected with Mycobacterium tuberculosis. It is restricted to the lung and accounts for 80% of cases and nearly 100% of transmission. Little is known about the immunopathology of postprimary tuberculosis due to limited availability of specimens. Tissues from 30 autopsy cases of pulmonary tuberculosis were located. Sections of characteristic lesions of caseating granulomas, lipid pneumonia, and cavitary stages of postprimary disease were selected for immunohistochemical studies of macrophages, lymphocytes, endothelial cells, and mycobacterial antigens. A higher percentage of cells in lipid pneumonia (36.1%) and cavitary lesions (27.8%) were positive for the dendritic cell marker …

Chondrosarcoma Of The Mobile Spine And Sacrum, Ryan M Stuckey, Rex A W Marco

Faculty, Staff and Student Publications

Chondrosarcoma is a rare malignant tumor of bone. This family of tumors can be primary malignant tumors or a secondary malignant transformation of an underlying benign cartilage tumor. Pain is often the initial presenting complaint when chondrosarcoma involves the spine. In the mobile spine, chondrosarcoma commonly presents within the vertebral body and shows a predilection for the thoracic spine. Due to the resistance of chondrosarcoma to both radiation and chemotherapy, treatment is focused on surgery. With en bloc excision of chondrosarcoma of the mobile spine and sacrum patients can have local recurrence rates as low as 20%.

Case Of “Slow” Stroke From Carotid Artery Occlusion Treated By Delayed But Cautious Endovascular Intervention, Kachi Illoh, Emilio Supsupin, Hashem M Shaltoni, Edwin D Cacayorin

Faculty, Staff and Student Publications

In a challenging case of carotid occlusion with slowly evolving stroke, we used brain imaging to facilitate endovascular revascularization resulting in the relief of the patient's symptoms. Patients with carotid occlusion and continued neurological worsening or fluctuations present enormous treatment challenges. These patients may present "slow" strokes with subacute infarcts that present significant challenges and risks during attempts at revascularization of the occluded artery. We present such a case in which we used multimodal imaging techniques, including MR-perfusion, to facilitate endovascular revascularization. Our approach of delayed but cautious intra-arterial thrombolytic therapy, guided by brain imaging, and followed by stent placement …

Measuring The Symptom Burden Of Lung Cancer: The Validity And Utility Of The Lung Cancer Module Of The M D Anderson Symptom Inventory, Tito R Mendoza, Xin Shelley Wang, Charles Lu, Guadalupe R Palos, Zhongxing Liao, Gary M Mobley, Shitij Kapoor, Charles S Cleeland

Faculty, Staff and Student Publications

We conducted a study to establish the psychometric properties of a module of the M. D. Anderson Symptom Inventory (MDASI) developed specifically for patients with lung cancer (MDASI-LC). The MDASI measures 13 common "core" symptoms of cancer and its treatment. The MDASI-LC includes the 13 core MDASI symptom items and three lung cancer-specific items: coughing, constipation, and sore throat. MDASI-LC items were administered to three cohorts of patients with lung cancer undergoing either chemotherapy or chemoradiotherapy. Known-group validity and criterion (concurrent) validity of the MDASI-LC were evaluated using the Eastern Cooperative Oncology Group performance status and the 12-item Short-Form Health …

Probing The Mechanical Properties Of Tnf-A Stimulated Endothelial Cell With Atomic Force Microscopy, Sei-Young Lee, Ana-Maria Zaske, Tommaso Novellino, Delia Danila, Mauro Ferrari, Jodie Conyers, Paolo Decuzzi

Faculty, Staff and Student Publications

TNF-α (tumor necrosis factor-α) is a potent pro-inflammatory cytokine that regulates the permeability of blood and lymphatic vessels. The plasma concentration of TNF-α is elevated (> 1 pg/mL) in several pathologies, including rheumatoid arthritis, atherosclerosis, cancer, pre-eclampsia; in obese individuals; and in trauma patients. To test whether circulating TNF-α could induce similar alterations in different districts along the vascular system, three endothelial cell lines, namely HUVEC, HPMEC, and HCAEC, were characterized in terms of 1) mechanical properties, employing atomic force microscopy; 2) cytoskeletal organization, through fluorescence microscopy; and 3) membrane overexpression of adhesion molecules, employing ELISA and immunostaining. Upon stimulation …
