Anorexia Nervosa And Reproduction: Connecting Brain To Gonads, Mihaela Poterasu, David L. Rowland, Corina Ciobanu, Simona Fica Apr 2020

Anorexia Nervosa And Reproduction: Connecting Brain To Gonads, Mihaela Poterasu, David L. Rowland, Corina Ciobanu, Simona Fica

Journal of Mind and Medical Sciences

Anorexia nervosa (AN) is a psychiatric disorder that predominantly affects young women and is characterized by low caloric intake and a major dissatisfaction with one’s body image. It is often overlooked and, while patients and family seek medical help, emaciation and nutritional misbalances may become extreme and potentially life threatening. Among the many somatic complications, an accumulation of early endocrine adaptations occurs, leading to functional amenorrhea and impaired reproduction as a result of dysfunction of the hypothalamic-pituitary-ovarian axis. Even though these conditions are reversible, long-term consequences may affect the fertility of women with AN and can lead to maternal and …

Department of Neurology Faculty Papers

Molecules from animal venoms are promising candidates for the development of new drugs. Previous in vitro studies have shown that the venom of the spider Phoneutria nigriventer (PnV) is a potential source of antineoplastic components with activity in glioblastoma (GB) cell lines. In the present work, the effects of PnV on tumor development were established in vivo using a xenogeneic model. Human GB (NG97, the most responsive line in the previous study) cells were inoculated (s.c.) on the back of RAG-/- mice. PnV (100 µg/Kg) was administrated every 48 h (i.p.) for 14 days and several endpoints were evaluated: tumor …


Phosphoinositides In Retinal Function And Disease, Theodore G Wensel Apr 2020

Phosphoinositides In Retinal Function And Disease, Theodore G Wensel

Faculty, Staff and Students Publications

Phosphatidylinositol and its phosphorylated derivatives, the phosphoinositides, play many important roles in all eukaryotic cells. These include modulation of physical properties of membranes, activation or inhibition of membrane-associated proteins, recruitment of peripheral membrane proteins that act as effectors, and control of membrane trafficking. They also serve as precursors for important second messengers, inositol (1,4,5) trisphosphate and diacylglycerol. Animal models and human diseases involving defects in phosphoinositide regulatory pathways have revealed their importance for function in the mammalian retina and retinal pigmented epithelium. New technologies for localizing, measuring and genetically manipulating them are revealing new information about their importance for the …

Follicular Sensitivity Index: A Tool To Predict Successful Conception After Intra-Cytoplasmic Sperm Injection, Rehana Rehman, Amara Zafar, Nida Zahid, Nuruddin Badruddin Mohammed

Department of Biological & Biomedical Sciences

Follicular sensitivity index (FSI) is used for estimation of follicular responsiveness to controlled ovarian hyperstimulation (COH) during intra-cytoplasmic sperm injection (ICSI). In a retrospective study, FSI of 1,385 females was calculated as [pre-ovulatory follicle count (PFC) × 100,000]/ [antral follicle count (AFC) × total received stimulation doses]. Females were then categorised into low, middle and high FSI groups according to FSI tertile values. FSI was 8.65 ±2.82 in non-pregnant as compared to 12.02 ±2.04 (p <0.01) in pregnant cohort. FSI turned out to be a strong predictor of successful conception on the receiver operating curve with cutoff value 10.36 at 76% specificity, sensitivity of 86% and area under the curve (AUC; 0.83). Calculation of FSI can thus predict the chances of successful conception in females with different causes of infertility.

An Investigation Into Differences In The Infant Intestinal Microbiome Based On Method Of Delivery, Savannah Whitney Apr 2020

An Investigation Into Differences In The Infant Intestinal Microbiome Based On Method Of Delivery, Savannah Whitney

Senior Honors Theses

The infant intestinal microbiome is greatly influenced by method of delivery in relation to bacterial composition, diversity, and richness. The intestinal tracts of cesarean delivered infants are more likely to be colonized with skin microbiota like Clostridium, Staphylococcus, Streptococcus, and Corynebacterium, and have less bacterial diversity and richness than their vaginally delivered counterparts, who are more likely to be colonized with Bacteroides, Bifidobacterium, and Lactobacillus, which are common vaginal bacteria. These microbial differences make cesarean delivered infants more likely to develop allergies, asthma, eczema, gastrointestinal conditions, obesity, and diabetes, among other diseases. Though vaginal seeding has been proposed …

Cofilin-1-Induced Actin Reorganization In Stored Platelets, Swapan K Dasgupta, Perumal Thiagarajan Apr 2020

Cofilin-1-Induced Actin Reorganization In Stored Platelets, Swapan K Dasgupta, Perumal Thiagarajan

Faculty, Staff and Students Publications

BACKGROUND: During platelet storage, there are extensive changes in cytoskeleton and phosphatidylserine exposure. The intrinsic mitochondrial pathway of apoptosis, activated in stored platelets, is a major mediator these changes. Cofilin-1 is an effector of actin reorganization. We examined the effect of cofilin-1 deficiency on cytoskeleton and phosphatidylserine exposure during storage and following activation of apoptosis.

METHODS AND RESULTS: We assessed actin filaments by Alexa-647-phalloidin and phosphatidylserine exposure by fluorescein isothiocyanate-lactadherin by fluorescence microscopy. In fresh platelets, actin filaments are distributed in the subcortical region, and they do not express phosphatidylserine in the outer surface. In stored platelets, there is retraction …

Aggressive myeloid leukemias such as blast crisis chronic myeloid leukemia and acute myeloid leukemia remain highly lethal. Here we report a genome-wide in vivo CRISPR screen to identify new dependencies in this disease. Among these, RNA-binding proteins (RBPs) in general, and the double-stranded RBP Staufen2 (Stau2) in particular, emerged as critical regulators of myeloid leukemia. In a newly developed knockout mouse, loss of Stau2 led to a profound decrease in leukemia growth and improved survival in mouse models of the disease. Further, Stau2 was required for growth of primary human blast crisis chronic myeloid leukemia and acute myeloid leukemia. Finally, …

Perinatal Drug Abuse And Neonatal Drug Withdrawal, Samarth Shukla, Lisa B. Zirkin, Enrique Gomez Pomar

Pediatrics Faculty Publications

Drug abuse and addiction have significantly increased over the last few decades; specifically, opioid abuse and dependence have increased to epidemic proportions. This increased use of drugs includes women of childbearing age and those who are pregnant. Drug abuse during pregnancy is a serious health risk for both mother and newborn infant. Infants exposed to maternal drugs in fetal life develop signs of drug withdrawal during early neonatal life. This group of withdrawal signs is known as neonatal abstinence syndrome (NAS). Although NAS is not a fatal condition, it results in significant illness and prolonged hospitalization.

Modified Danielson Technique For Prosthetic Aortic Valve Endocarditis And Aortoventricular Discontinuity, Gianfranco Filippone, Claudia Calia, Mario Finazzo, Fabio Fazzari, Giovanni Caruana, Vincenzo Argano

The Texas Heart Institute Journal

Endocarditis is a devastating complication of prosthetic aortic valve replacement. The infective process can destroy aortic annulus tissue, making conventional surgical valve replacement difficult or impossible and causing aortoventricular discontinuity. Several treatment techniques have been proposed. One of these, the Danielson technique, involves translocating the aortic valve to the native ascending aorta, débriding the abscess cavity, closing the coronary ostia, and bypassing the coronary arteries with a Y anastomosis between 2 vein grafts. We describe our use of a modified Danielson technique in a 68-year-old man with advanced prosthetic valve endocarditis that was associated with aortic annulus destruction and aortoventricular …
