Molecular And Cellular Biology Of Prostate Cancer, El-Nasir Lalani, Marc Elie Laniado, Paul David Abel
El Nasir Lalani
Prostate cancer is an enigmatic disease. Although prostatic-intraepithelial neoplasia appears as early as the third decade and as many as 80% of 80 year old men have epithelial cells in their prostate that fit the morphological criteria for cancer, only about 10% of men will ever have the clinical disease and less than 3% will die from it. There have been no significant proven interventions which have altered the natural history of the disease since hormone down regulation was introduced in the 1940s and new research has been poorly supported. There is however an urgent need to develop new criteria ...

IMPORTANCE: The expected duration of menopausal vasomotor symptoms (VMS) is important to women making decisions about possible treatments.
OBJECTIVES: To determine total duration of frequent VMS ( > /= 6 days in the previous 2 weeks) (hereafter total VMS duration) during the menopausal transition, to quantify how long frequent VMS persist after the final menstrual period (FMP) (hereafter post-FMP persistence), and to identify risk factors for longer total VMS duration and longer post-FMP persistence.
DESIGN, SETTING, AND PARTICIPANTS: The Study of Women's Health Across the Nation (SWAN) is a multiracial/multiethnic observational study of the menopausal transition among 3302 women enrolled at ...
Ultrasonography Of The Scrotum In Adults, 2016 University of Massachusetts Medical School
Ultrasonography Of The Scrotum In Adults, Anna L. Kuhn, Eduardo Scortegagna, Kristina M. Nowitzki, Young H. Kim
Radiology Publications and Presentations
Ultrasonography is the ideal noninvasive imaging modality for evaluation of scrotal abnormalities. It is capable of differentiating the most important etiologies of acute scrotal pain and swelling, including epididymitis and testicular torsion, and is the imaging modality of choice in acute scrotal trauma. In patients presenting with palpable abnormality or scrotal swelling, ultrasonography can detect, locate, and characterize both intratesticular and extratesticular masses and other abnormalities. A 12-17 MHz high frequency linear array transducer provides excellent anatomic detail of the testicles and surrounding structures. In addition, vascular perfusion can be easily assessed using color and spectral Doppler analysis. In most ...
Ramadan & Pregnancy, 2016 Augustana College, Rock Island Illinois
Ramadan & Pregnancy, Omar Rizvi
Celebration of Learning
Fasting during Ramadan, the ninth month of the Muslim calendar, is one of the five pillars of Islam and is fard (obligatory) for all Muslims physically and mentally capable of doing so. In the Qur’an, it is made abundantly clear that religion and its acts of worship are not meant to pose undue difficulty or hardship (Qur’an 22:78, 5:6, 2:185). My paper explores the Islamic definitions for “unnecessary difficulty” and “physically capable” specifically in regards to pregnant women. At what point does fasting incur significant, if any, damage to the fetus that it should prevent ...
Acute Kidney Injury Biomarkers: A Prospective Cohort Study In Urological Patients, 2016 The University of Western Ontario
Acute Kidney Injury Biomarkers: A Prospective Cohort Study In Urological Patients, Daniel Olvera-Posada
Electronic Thesis and Dissertation Repository
Several recent studies have assessed the use of biomarkers of Acute Kidney Injury (AKI), but the information among patients with stone disease and those with obstructive uropathy is limited. For this reason, we conducted a prospective cohort study to determine the urinary levels of KIM-1, Total and Monomeric NGAL in patients with hydronephrosis secondary to renal stone disease, congenital ureteropelvic junction obstruction or ureteral stricture, and in a group of healthy controls in our health care center. Urinary biomarker concentrations were evaluated before and after surgical treatment. Patients with hydronephrosis showed significantly higher baseline levels of KIM-1 compared to those ...

Long-Lasting Effects Of Perinatal Exposure To Brominated Flame Retardant On Male Reproductive Outcomes In Rat Model, Ahmed Khalil, Daneal Portman, Jake Jensen, Michael Panchenko, Alexander Suvorov
UMass Center for Clinical and Translational Science Research Retreat
Meta-analysis of 101 studies published between 1934 and 1996 indicates that mean sperm concentration decreased around 50% during this period. More recent studies have found alarmingly poor semen quality in the general population of Northern Europe. Additional adverse trends include increased incidence of testicular cancer, and congenital malformations such as cryptorchidism and hypospadias. Testicular germ cell cancers increased by about 400% over the period of 50 years in industrialized countries. Decreased quality of male reproductive health has been linked to environmental endocrine disruptors exposure. However, the ability of xenobiotics to produce long-lasting effects and mechanisms of perturbation of the male ...
Urinary Alkalisation For Symptomatic Uncomplicated Urinary Tract Infection In Women (Review), Dermot B. O'Kane, Sameer Dave, Neel Gore, Farhaan Patel, Tammy Hoffmann, Jeanne L. Trill, Chris Del Mar
Christopher Del Mar
Uncomplicated urinary tract infection (UTI) is the most common bacterial infection in women, characterised by dysuria and urinary frequency. Urinary alkalisers are widely used in some countries for the symptomatic treatment of uncomplicated UTI, and they are recommended in some national formularies. However, there is a lack of empirical evidence to support their use for UTI and some healthcare guidelines advise against their use.
We aimed to look at the benefits and harms of the use of urinary alkalisers for the treatment of uncomplicated UTIs in adult women.
We searched the Cochrane Kidney and Transplant Specialised ...
Embryo Adoption As An Ethical Option For Couples Faced With Infertility, 2016 Liberty University
Embryo Adoption As An Ethical Option For Couples Faced With Infertility, Rachel M. Walters
Senior Honors Theses
Embryo adoption takes embryos that are still forming and introduces them into the uterus of a woman with whom they do not share any genetic material. If pregnancy does ensue and continues without complications, the child that will be born will not share any genes with the woman who carried him or her. In addition, if the child is born to parents who already have other children, the children in the adoptive family will share no biological link to the newborn. Essentially, the child will have two families—a biological family and an adoptive family. This thesis will explore and ...

Education Intervention Of Preconception Screening In Primary Care, Tracy Schuler
Doctor of Nursing Practice (DNP) Capstone Projects
Problem: The risk of a poor pregnancy outcome among women of reproductive age in Providence, Rhode Island is indicated by the high rates of unintended pregnancies, low multivitamin use prior to pregnancy, obesity, and smoking. Although recommended, health professionals often fail to routinely screen and educate women of reproductive age for preconception risk factors. Purpose: Evaluate the efficacy of an educational intervention on preconception risk factors, lifestyle modifications, and current screening recommendations; and introduce a preconception tool and education sheet among a population of health care providers. Method: Preconception health material and a modified preconception screening tool was presented to ...

Urine is a metabolite-rich biofluid that reflects the body’s effort to maintain chemical and osmotic homeostasis. Clinical diagnosis routinely relies on urine samples because the collection process is easy and noninvasive. Despite these advantages, urine is an under-investigated source of biomarkers for multiple sclerosis (MS). Nuclear magnetic resonance spectroscopy (NMR) has become a common approach for analyzing urinary metabolites for disease diagnosis and biomarker discovery. For illustration of the potential of urinary metabolites for diagnosing and treating MS patients, and for differentiating between MS and other illnesses, 38 urine samples were collected from healthy controls, MS patients, and neuromyelitis ...
Human Oocytes And Embryos Viewed By Time-Lapse Videography, And The Development Of An Embryo Deselection Model, 2016 Edith Cowan University
Human Oocytes And Embryos Viewed By Time-Lapse Videography, And The Development Of An Embryo Deselection Model, Yanhe Liu
Theses: Doctorates and Masters
Despite its wide application today, in vitro fertilization (IVF) treatment continues to have relatively low efficacy, largely due to inaccuracy in selecting the best quality embryo(s) from the cohort for transfer. Novel methodologies for improved selection are being developed, and time-lapse observation of human embryos is gaining increasing popularity due to the more detailed morphokinetic information obtained plus uninterrupted culture conditions. The morphokinetic information enables the use of quantitative timings in developmental milestones of embryos and qualitative measures of abnormal biological events, to assist embryo selection/deselection. This project aimed to identify current limitations in the use of such ...

Brian K Whitlock, PhD, DVM, DACT
Kisspeptin receptor (KISS1R) agonists with increased half-life and similar efficacy to kisspeptin in vitro may provide beneficial applications in breeding management of many species. However, many of these agonists have not been tested in vivo. These studies were designed to test and compare the effects of a KISS1R agonist (FTM080) and kisspeptin on luteinizing hormone (LH) in vivo. In experiment 1 (pilot study), sheep were treated with FTM080 (500 pmol/kg BW) or sterile water (VEH) intravenosuly. Blood was collected every 15 min before (1 h) and after (1 h) treatment. In experiment 2, sheep were treated with KP-10 (human ...
Characterization Of The Nicotine-Induced Endoplasmic Reticulum Stress Response In The Rat Placenta In Vivo And In Vitro, 2015 The University of Western Ontario
Characterization Of The Nicotine-Induced Endoplasmic Reticulum Stress Response In The Rat Placenta In Vivo And In Vitro, Michael Ka Chun Wong
Electronic Thesis and Dissertation Repository
Nicotine exposure during pregnancy leads to adverse health outcomes, including compromised placental development. Although the molecular mechanisms remain elusive, recent studies identified that endoplasmic reticulum (ER) stress may underlie poor placentation. Therefore, we were interested in investigating the effects of nicotine exposure on the ER stress response in the placenta. A well-established maternal nicotine exposure rat model and Rcho-1 trophoblast giant cell model were utilized to address the research questions. Maternal nicotine exposure in vivo led to elevated ER stress in association with impaired disulfide bond formation and hypoxia. Nicotine exposure in vitro further differentiated that ER stress may be ...

Implantable Device For Wireless Regulation Of The Bladder Through Pelvic Nerve Stimulation, 2015 Purdue University
Implantable Device For Wireless Regulation Of The Bladder Through Pelvic Nerve Stimulation, Kelsey C. Bayer, Chris Quinkert, Pedro Irazoqui
The Summer Undergraduate Research Fellowship (SURF) Symposium
Urinary incontinence (UI) is the involuntarily urination that usually effects older people or is the result of an injury. UI affects more than eleven million people and the cost of incontinence management in the United States in 2000 was $19.5 billion. Where conventional physical therapies have failed, pelvic nerve stimulation is a promising form of regulating the bladder long term. Piezoresistive pressure sensors consist of two variable resistance values and two known resistance values that are represented on a daughterboard. This unknown resistance represents the change in pressure. The filling and voiding of the bladder was characterized through acute ...

BACKGROUND: In animal studies, organochlorine pesticide (OCP) exposure alters pubertal development; however, epidemiological data are limited and inconsistent. OBJECTIVE: To evaluate the associations of serum OCP concentrations [hexachlorobenzene (HCB), beta-hexachlorocyclohexane (beta-HCH), and p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE)] with male pubertal onset. METHODS: In Chapaevsk, Russia, a town environmentally contaminated with OCPs, 350 8-9 year old boys with measured OCPs were enrolled during 2003-2005 and were followed annually for eight years. We evaluated three measures of pubertal onset: testicular volume (TV) > 3 mL in either testis, or stage 2 or greater for genitalia (G2+), or pubic hair (P2+). We used ...
Association Between Chlorinated Pesticides In The Serum Of Prepubertal Russian Boys And Longitudinal Biomarkers Of Metabolic Function, Jane Burns, Paige Williams, Susan Korrick, Russ Hauser, Oleg Sergeyev, Boris Revich, Thuy Lam, Mary Lee
Mary M. Lee
Organochlorine pesticides (OCPs) have been linked to adult metabolic disorders; however, few studies have examined these associations in childhood. We prospectively evaluated the associations of baseline serum OCPs (hexachlorobenzene, beta-hexachlorocyclohexane, and p,p'-dichlorodiphenyldichloroethylene) in Russian boys with subsequent repeated measurements of serum glucose, insulin, lipids, leptin, and calculated homeostatic model assessment of insulin resistance (IR). During 2003-2005, we enrolled 499 boys aged 8-9 years in a prospective cohort; 318 had baseline serum OCPs and serum biomarkers measured at ages 10-13 years. Multivariable generalized estimating equation and mediation regression models were used to examine associations and direct and indirect (via ...

BACKGROUND: Few human studies have evaluated the impact of childhood exposure to organochlorine pesticides (OCP) on pubertal development.
OBJECTIVE: To evaluate associations of serum OCP concentrations [hexachlorobenzene (HCB), beta-hexachlorocyclohexane (beta-HCH), and p,p-dichlorodiphenyldichloroethylene (p,p'-DDE)] with age at attainment of sexual maturity among boys.
METHODS: From 2003-2005, 350 8-9 year-old boys from Chapaevsk, Russia with measured OCPs were enrolled and followed annually for eight years. We used multivariable interval-censored models to evaluate associations of OCPs (quartiles) with three physician-assessed measures of sexual maturity: Tanner stage 5 for genitalia growth, Tanner stage 5 for pubic hair growth, or testicular volume ...
Effect Of Curcumin Analog Ca27 On Androgen Receptor Translocation In Prostate Cancer Cells, 2015 Chapman University
Effect Of Curcumin Analog Ca27 On Androgen Receptor Translocation In Prostate Cancer Cells, Lijah Vann Gardner
Student Research Day Abstracts and Posters
The androgen receptor (AR) plays an essential role in promoting the development and progression of metastatic prostate cancer and represents an important molecular target for therapeutic intervention. We have recently described a series of synthetic analogs of the natural product diferuloylmethane (curcumin), some of which induce the down-regulation of AR expression in prostate cancer cells by an as yet largely unknown mechanism of action. While such analogs may in the long term be lead structures for the development of therapeutic drugs, we hypothesize here that they represent ideal molecular probes to identify the mechanism(s) of action for AR down-regulation ...
