Overexpression Of Mcl-1 Attenuates Liver Injury And Fibrosis In The Bile Duct-Ligated Mouse., Alisan Kahraman, Justin L. Mott, Steven F. Bronk, Nathan W. Werneburg, Fernando J. Barreyro, Maria E. Guicciardi, Yuko Akazawa, Karen Braley, Ruth W. Craig, Gregory J. Gores

Journal Articles: Biochemistry & Molecular Biology

Hepatocyte apoptosis contributes to liver injury and fibrosis after cholestatic injury. Our aim was to ascertain if the anti-apoptotic protein Mcl-1 alters liver injury or fibrosis in the bile duct-ligated mouse. Markers of apoptosis and fibrosis were compared in wild-type and transgenic mice expressing human Mcl-1 after bile duct ligation. Compared to hMcl-1 transgenic animals, ligated wild-type mice displayed a significant increase in TUNEL-positive cells and in caspase 3/7-positive hepatocytes. Consistent with apoptotic injury, the pro-apoptotic protein Bak underwent a conformational change to an activated form upon cholestatic injury, a change mitigated by hMcl-1 overexpression. Likewise, liver histology, number of …

Faculty Field Guide For Promoting Student Civility In The Classroom, Cynthia Clark

Nursing Faculty Publications and Presentations

Student incivility is defined as rude and disruptive behavior that, when left unaddressed, may spiral into aggressive or violent behavior. Nursing faculty are challenged by uncivil student behavior and many are underprepared to deal with its effects. Some faculty members consider leaving academe due to the serious toll incivility often takes on their personal and professional lives. The impact of student incivility on faculty is especially troubling during a national nursing shortage. The author provides nursing faculty with several ready-to-use strategies for preventing and effectively dealing with student incivility in nursing education.

Atp Release By Infected Bovine Monocytes Increases The Intracellular Survival Of Mycobacterium Avium Subsp. Paratuberculosis, Seng-Ryong Woo, Raul G. Barletta, Charles Czuprynski

School of Veterinary and Biomedical Sciences: Faculty Publications

Mycobacterium avium subsp. paratuberculosis is the etiologic agent of Johne’s disease, a chronic intestinal infection in ruminants. Adenosine 5′-Triphosphate (ATP) has been reported to induce killing of several Mycobacterium species in human and murine macrophages. We investigated whether ATP secreted from M. avium subsp. paratuberculosis-infected bovine monocytes affects intracellular survival of the bacilli. Bovine monocytes constitutively secreted ATP during an 8-day incubation period in vitro; however, M. avium subsp. paratuberculosis infection did not enhance ATP release. Removal of extracellular ATP by the addition of apyrase increased the viability of infected monocytes, but surprisingly decreased the number of viable intracellular …

Counting On Care Work: Human Infrastructure In Massachusetts, Randy Albelda, Mignon Duffy, Nancy Folbre

Center for Social Policy Publications

In Massachusetts, as in every other place in the world, all children need to be cared for and educated, everybody has physical and mental health needs that require attention, and some individuals need assistance with the daily tasks of life because of illness, age, or disability. The labor of meeting these needs – which we call care work – is a complex activity that has profound implications for personal, social and economic well-being. Care work is not just a cornerstone of our economy – it is a rock-bottom foundation. Care work provides the basis for our human infrastructure, and we …

The Cca Anticodon Specifies Separate Functions Inside And Outside Translation In Bacillus Cereus, Sandro F. Ataide, Theresa E. Rogers, Michael Ibba

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Bacillus cereus 14579 encodes two tRNAs with the CCA anticodon, tRNA^Trp and tRNA^Other. tRNA^Trp was separately aminoacylated by two enzymes, TrpRS1 and TrpRS2, which share only 34% similarity and display different catalytic capacities and specificities. TrpRS1 was 18-fold more proficient at aminoacylating tRNA^Trp with Trp, while TrpRS2 more efficiently utilizes the Trp analog 5-hydroxy Trp. tRNA^Other was not aminoacylated by either TrpRS but instead by the combined activity of LysRS1 and LysRS2, which recognized sequence elements absent from tRNA^Trp. Polysomes were found to contain tRNA^Trp, consistent with its role in …

Delirium Screening: From Research To Point Of Care, Beth Ann Swan, Phd, Crnp, Faan, Sheena Ahlawat, Mph, Christopher N. Sciamanna, Md, Phd

College of Nursing Faculty Papers & Presentations

Delirium is a serious public health problem among older adults and is one of the most common cognitive disorders affecting postoperative older adults. Delirium is a treatable illness that disproportionately places postoperative older adults at increased risk for functional and cognitive decline, as well as increased morbidity and mortality. More than 50 percent of postoperative patients develop delirium during hospitalization. Epidemiologic and clinical studies over the past two decades have provided ample evidence that delirium in hospitalized older adults is under-recognized by nurses and physicians, often leading to untoward events that the safety and well-being of hospitalized older adults.

Thyroid Lymphosonography: A Novel Method For Evaluating Lymphatic Drainage., Joseph M. Curry, Waleed H. Ezzat, Daniel A. Merton, Barry B. Goldberg, David M. Cognetti, David Rosen, Edmund A. Pribitkin

Department of Otolaryngology - Head and Neck Surgery Faculty Papers

OBJECTIVES: We evaluated lymphosonography, or contrast-enhanced, ultrasonography (US)-guided sentinel lymph node (SLN) detection, as a technique for demonstrating the lymphatic drainage of the thyroid gland. METHODS: In this prospective animal study, four 50-kg Yorkshire swine underwent transcutaneous injection of a US contrast agent and methylene blue dye into the thyroid gland. Contrast-enhanced US was used to identify draining lymphatic channels and SLNs. Sentinel node biopsy was conducted. Subsequently, bilateral neck and upper mediastinal dissection was carried out. RESULTS: In 3 of 4 cases, a blue dye-positive and US contrast-positive SLN was identified. We identified SLNs in level IV in 2 …

Impact Of Ambient Air Pollution On Survival Of Renal Transplant Recipients, Rhonda Kristine Hwang

Loma Linda University Electronic Theses, Dissertations & Projects

There is increasing evidence that ambient air pollution is associated with coronary heart disease morbidity and mortality. This research has focused on the general public and less so on possible sensitive subgroups even though these may have even greater susceptibility to adverse effects of ambient air pollution. With highly prevalent traditional as well as nontraditional risk factors, renal transplant recipients may potentially be a sensitive subgroup. The purpose of this study was to evaluate the possible effect of between long-term exposure to air pollution on the risk of CHD mortality among renal transplant recipients. This cohort study includes 32,239 adult, …

Loma Linda University Electronic Theses, Dissertations & Projects

This descriptive, correlational study described the type, frequency, and correlates of nurses' spiritual care practices (quantitative) and their experiences with the sacred at work (qualitative). A convenience sample of 554 (24%) of the Registered Nurses employed at a western United States faith-based tertiary care health system participated in this online survey. Nurses' spiritual care practices were assessed using the 17-item Nurses' Spiritual Care Practice Questionnaire (NSCQ). Factorial validity and reliability of the pilot NSCQ were established. Spiritual care practices most frequently endorsed were assessing patients' spiritual beliefs pertaining to health and listening to patients' stories of illness and their spiritual …

Neurodevelopmental Outcome & Mr Spectroscopy Of Therapeutic Hypothermia After Pediatric Drowning, Sharon Mieras Perugini

Loma Linda University Electronic Theses, Dissertations & Projects

Despite advances in medical treatment and technology, outcome following pediatric drowning can vary widely from mild to severe impairments and death. Prognosis is often difficult to predict given a number of contributing factors. As such, this study examined the relationship between clinical indicators including submersion duration, initial GCS and PRISM scores, and waking time with outcome as well as metabolite ratios based on magnetic resonance spectroscopy. Research stemming from the area of cardiac arrest as well as anecdotal case study reports of cold water drownings suggests that lowering the body temperature may be helpful and protective. As such, the use …

Using Cone Beam Computed Tomography To Identify A Prediction Model For Obstructive Sleep Apnea, Jodi Parker

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Obstructive Sleep Apnea (OSA) patients have increased risk of morbidity and mortality. Early diagnosis may reduce morbidity and mortality. Prediction of OSA from imaging may help to identify OSA patients earlier in life. CBCT can be used for OSA diagnostic imaging due to its three-dimensional (3D) visualization of the upper airway and craniofacial complex. Magnification associated with conventional 2D radiography is eliminated with CBCT, and radiation to the patient is significantly less than previous modalities used to measure craniofacial & airway measurements associated with OSA. During a CBCT scan, the patient's image is taken supine, rather than the upright …

Effects Of Functional Appliances On The Tmj And Mandibular Length Of Skeletal Class Ii Patients: A Cone Beam Computed Tomography Study, David C. Lee

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Functional appliances have been efficiently used in the treatment of Class II malocclusions caused by retrognathic mandibles. Cone beam computed tomography has enabled us to make more accurate linear measurements by eliminating superimposition of other structures and to analyze skeletal anatomic detail in all three planes of space. This retrospective study evaluated the osseous changes in the temporomandibular joint (TMJ) and length of the mandible in skeletal Class II malocclusion patients treated with the fixed functional appliances and compared measurements with Class I malocclusion patients treated with orthodontic mechanics that did not alter skeletal relationships.

Comparison Of Rationally-Derived And Empirically-Derived Methods For Predicting Failure In Residential Treatment, Jennifer Pester Grattan

Loma Linda University Electronic Theses, Dissertations & Projects

Patient-focused research methods have been used in adult mental health treatment to improve outcomes by tracking individual treatment response and comparing it with expected recovery patterns. One such approach has used rationally- and empirically-derived methods to analyze data from the OQ-45 and identify patients who are not responding as expected to treatment. Treatment is then adjusted, improving outcomes and lowering overall costs.

Similar but less extensive research has shown analogous methods can be used with children and adolescents. This would be particularly useful in residential treatment, which is an expensive and inadequately researched approach. This study used archival data gathered …

Patient/Physician Communication In Type 2 Diabetes-Related Health Behavior Change, Barbara Marie Thomas

Loma Linda University Electronic Theses, Dissertations & Projects

Adult type 2 diabetes is an increasing problem in the United States and affected over 16 million Americans in 2004. Most patients are treated in primary care settings and managed medically, but controlling insulin resistance through activity and diet is considered the greatest challenge for the next 30 years (Katen, et al., 2007). Understanding how physicians and patients communicate about health behaviors is necessary for developing the most effective strategies for facilitating health behavior change in this population. In the current study, adults with type 2 diabetes (n= 87) from the Loma Linda University Diabetes Treatment Center (LLUDTC), …

The Influence Of Work Of Fracture On Six Orthodontic Bonding Systems, Tyler S. Pritchard

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Bonding is the primary method of attaching brackets to teeth in modem orthodontics. Thus, many studies have focused on the maximum shear bond strength values of orthodontic adhesives. In contrast, very little research has been performed considering the work of fracture of orthodontic bonding systems. Work of Fracture is defined as the area under the curve of a stress-strain graph. Previous shear bond strength studies measured the force necessary to produce bond failure. The purpose of this study was to measure the maximum shear force and displacement of six bonding systems and to calculate the work of fracture.

Influence Of Stainless Steel Orthodontic Brackets On Magnetic Resonance Imaging, Christian James Hoybjerg

Loma Linda University Electronic Theses, Dissertations & Projects

Introduction: Magnetic resonance imaging (MRI) machines provide 2D as well as 3D images that are excellent in contrasting soft-tissue in the maxillofacial region and are void of ionizing radiation. The drawbacks include the lack of depiction of cortical bony detail and image degradation caused by substances in the scanned area. Specifically, in the orthodontic field stainless steel brackets cause more distortion of MR images then any other bracket material. It is unknown what type of stainless steel alloy causes the most MRI distortion. The purpose of this study is to evaluate the degree of craniofacial MR distortion caused by various …

The Effects Of The Introduction Of An Electronic Medical Record (Emr) On Self-Reported Treatment Effects In A Psychological Service In A Family Medicine Clinic, Michael D. Herman

Loma Linda University Electronic Theses, Dissertations & Projects

The healthcare system in the United States has traditionally focused on pathogenic disease prevention and treatment of acute illness, only addressing physical health (Grzywacz & Keyes, 2004). This approach is limited, as it does not often acknowledge the influence of mental health and health promotion on outcomes. Approximately, 25-75% of all presenting cases with uncertain etiology in medicine are psychosocial or behavioral in origin (Schulte et. al., 2004). Improvements can be made through integrated care; however, divergent viewpoints and often proximity across providers disrupts, psychologist-physician communication, collaboration, and subsequently care access (McDaniel, 1995). The current study examines the self reported …

Study Of The Four Factor Theory Of Women’S Sexual Function, Julie M. Merrell

Loma Linda University Electronic Theses, Dissertations & Projects

Tiefer, Hall, and Tavris (2002) described factors comprising four categories of female sexual function. They suggested that unique factors need to be examined to understand sexual function in women. Socio-cultural, political, or economic factors, partner and relationship factors, psychological factors, and medical factors were described as aspects of women’s lives that can be the source of sexual dysfunction. In a previous study, Merrell (2007) utilized Tiefer et al’s (2002) four factor model of sexual functioning to examine female sexual functioning looking specifically at body shame, relationship satisfaction, positive and negative affect, sexual self-schema, and overall health. Based on the results …
