Organized Caudal Photoreceptors In The Medicinal Leech, Baylee Bancroft

Honors Theses

Visual systems are essential to an organism’s survival. There are a wide range of photosensory organs across the animal kingdom, varying by means of structure, complexity, and the way in which they transduce information. Regardless of variation, visual systems provide the organism with information regarding external stimuli based on how light interacts with surrounding matter. The medicinal leech, Hirudo verbana, is one of the many important model organisms of neurobiology as this segmented annelid possesses a relatively simple nervous system and a rudimentary visual system. The leech also exhibits a restricted range of quantifiable overt behaviors and is capable of …

Awareness Regarding Causes Of Infertility Among Out-Patients At A Tertiary Care Hospital In Karachi, Pakistan, Hamza M. Ahmed, Mohammad Khan, Farah Yasmin, Haris Jawaid, Hiba Khalid, Anum Shigri, Faryal Nawaz, Choudhary A. Hasan

Section of Internal Medicine

Introduction: Infertility is the inability of a couple to achieve pregnancy within 12 months of sexual intercourse without the use of contraceptives. The Pakistani population, belonging to a low-middle income country, has a high prevalence of infertility due to a low knowledge and awareness regarding its causes, and lack of healthcare-seeking behavior for this medical issue. The prevalence of infertility in Pakistan is reported as 22%, with primary infertility accounting for 4% of the total cases. This leads to psychological trauma among women as societal norms equate infertility with failure on a personal, emotional, and social level. In this study, …

Diagnosis And Management Of Common Hand Infections., Vivek K. Bilolikar, Daniel A Seigerman, Asif M. Ilyas

Rothman Institute Papers

• While many hand infections are superficial, diligent evaluation, diagnosis, and treatment of these infections are central for preventing disability and morbidity.
• Maintaining a wide differential diagnosis is important as some hand infections may mimic others.
• In geographic areas with more than a 10% to 15% prevalence of community-acquired methicillin-resistant Staphylococcus aureus (MRSA) hand infections, empiric antibiotics should adequately cover MRSA.
• Once culture results are available, antibiotic regimens should be narrowed to reduce the development of resistant pathogens.

Faculty, Staff and Students Publications

Systemic inflammation can lead to coagulopathy and disseminated intravascular coagulation (DIC). In prior studies, the recombinant A2 domain of human von Willebrand factor (VWF; A2 protein) attenuated DIC and decreased mortality in lipopolysaccharide (LPS)-treated mice. Here, we performed studies to dissect the mechanism by which the A2 protein moderates DIC. We used confocal microscopy to analyze the fibrin clot structure in plasma from healthy humans and endotoxemic mice, turbidity assays to examine fibrin polymerization, and a murine model for LPS-induced DIC and introduced a loss-of-function mutation into the A2 protein for fibrin. The mutation of the residue E1567 located in …

Identifying the causal gene(s) that connects genetic variation to a phenotype is a challenging problem in genome-wide association studies (GWASs). Here, we develop a systematic approach that integrates mouse liver co-expression networks with human lipid GWAS data to identify regulators of cholesterol and lipid metabolism. Through our approach, we identified 48 genes showing replication in mice and associated with plasma lipid traits in humans and six genes on the X chromosome. Among these 54 genes, 25 have no previously identified role in lipid metabolism. Based on functional studies and integration with additional human lipid GWAS datasets, we pinpoint Sestrin1 as …

Microbiota: The Missing Link In The Etiology Of Inflammatory Bowel Disease, Micu Ioan Sergiu, Madalina Elena Manea, Musat Marilena, Dumitru Andrada, Popoiag Roxana Emanuela

Journal of Mind and Medical Sciences

Within its twisted and tight walls, where a hostile and arid environment prevails, the lumen of the digestive tract nests a true microuniverse called the microbiota. The existing relationship between humans and these microorganisms is one in which both benefit, creating a condition called Eubiosis.

The dynamic relationship existing between the microbiota and the human body can be affected at various times, leading to an imbalance that may have important implications on health and generating a condition called Disbiosis.

Recent studies have highlighted possible links between several diseases with incompletely elucidated etiology and disturbances of the microbiota. In this review …

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 …

The Lysosomal Diseases Testing Laboratory: A Review Of The Past 47 Years., David A. Wenger, Paola Luzi

Department of Neurology Faculty Papers

Lysosomal disorders are diseases that involve mutations in genes responsible for the coding of lysosomal enzymes, transport proteins, activator proteins and protein processing enzymes. These defects lead to the storage of specific metabolites within lysosomes resulting in a great variety of clinical features depending on the tissues with the storage, the storage products and the extent of the storage. The methods for rapidly diagnosing patients started in the late 1960's when the enzyme defects were identified eliminating the need for tissue biopsies. The first requests for diagnostic help in this laboratory came in 1973. In that year, patients with Krabbe …

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

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 …
