Response Of Obesity-Resistant Balb/C Mice To A Ketogenic Diet, Ana L. Cantú Ruiz, Diana E. Caballero Hernández, Ana C. Martínez Torres, Ricardo Gomez Flores, Patricia Tamez Guerra, Cristina Rodríguez Padilla

Research Symposium

Introduction. The ketogenic diet (KD) is a high-fat, low-carbohydrate diet in which the body undergoes metabolic adjustments that stimulate ketogenesis, thereby increasing circulating ketone bodies. Loss of body weight is attributed to these adjustments, as well as neuroprotective properties. However, the mechanisms involved are still not fully elucidated. That aim of this work was to evaluate the effect of a ketogenic diet on body composition, feeding behavior and glucose metabolism in mice of the BALB/c strain, a mouse model resistant to obesity.

Materials and methods. BALB/c mice of both sexes, 12 weeks old, were divided into KD and control …

Synlight: A Bicistronic Strategy For Simultaneous Active Zone And Cell Labeling In The Drosophila Nervous System, Michael A. Aimino, Jesse Humenik, Michael J. Parisi, Juan Carlos Duhart, Timothy J. Mosca

Farber Institute for Neuroscience Faculty Papers

At synapses, chemical neurotransmission mediates the exchange of information between neurons, leading to complex movement, behaviors, and stimulus processing. The immense number and variety of neurons within the nervous system make discerning individual neuron populations difficult, necessitating the development of advanced neuronal labeling techniques. In Drosophila, Bruchpilot-Short and mCD8-GFP, which label presynaptic active zones and neuronal membranes, respectively, have been widely used to study synapse development and organization. This labeling is often achieved via the expression of 2 independent constructs by a single binary expression system, but expression can weaken when multiple transgenes are expressed by a single driver. Recent …

Impacts Of Skin Color And Hypoxemia On Noninvasive Assessment Of Peripheral Blood Oxygen Saturation: A Scoping Review, Kawaiola C. Aoki, Maya Barrant, Mam Jarra Gai, Marina M. Handal, Vivian Xu, Harvey N. Mayrovitz

HPD Articles

Standard pulse oximeters estimate arterial blood saturation (SaO2 ) non-invasively by emitting and detecting light of a specific wavelength through a cutaneous vascular bed, such as a digit or the ear lobe. The quantity measured at these peripheral sites is designated as oxygen saturation (SpO2 ). Most reliable pulse oximeters are calibrated from measurements of healthy volunteers using some form of oxygen desaturation method. As the degree of inducible hypoxemia is limited, the calibration below achievable desaturation levels is usually extrapolated, leading to potential measurement error at low SaO2 values, especially in highly pigmented skin. Such skin color-related errors (SCRE) …

Patient Specific Normalized Glandular Dose Range Estimate For Mammography, Lacey Medlock

LSU Master's Theses

Breast cancer is the most common type of cancer among women in the United States. It is also the second leading cause of death by cancer among women in the United States. Early detection is key to preventing fatalities. There are over 39 million mammography screening procedures performed yearly [3]. We know that exposure to radiation, including in routine mammography, may induce secondary cancers [4]. Thus, it is important to be able to accurately estimate the dose delivered to a patient during breast cancer screening. The dose delivered to a patient is regulated in the US and in many other …

Methamphetamine-Induced Region-Specific Transcriptomic And Epigenetic Changes In The Brain Of Male Rats, Benpeng Miao, Xiaoyun Xing, Viktoriia Bazylianska, Pamela Madden, Anna Moszczynska, Bo Zhang

2020-Current year OA Pubs

Psychostimulant methamphetamine (METH) is neurotoxic to the brain and, therefore, its misuse leads to neurological and psychiatric disorders. The gene regulatory network (GRN) response to neurotoxic METH binge remains unclear in most brain regions. Here we examined the effects of binge METH on the GRN in the nucleus accumbens, dentate gyrus, Ammon's horn, and subventricular zone in male rats. At 24 h after METH, ~16% of genes displayed altered expression and over a quarter of previously open chromatin regions - parts of the genome where genes are typically active - showed shifts in their accessibility. Intriguingly, most changes were unique …

Propofol Affords No Protection Against Delayed Cerebral Ischemia In A Mouse Model Of Subarachnoid Hemorrhage, Meizi Liu, Keshav Jayaraman, James W Nelson, Jogender Mehla, Deepti Diwan, Ananth K Vellimana, Gregory J Zipfel, Umeshkumar Athiraman

2020-Current year OA Pubs

Delayed cerebral ischemia (DCI) is an important contributor to poor outcomes in aneurysmal subarachnoid hemorrhage (SAH) patients. We previously showed that volatile anesthetics such as isoflurane, sevoflurane and desflurane provided robust protection against SAH-induced DCI, but the impact of a more commonly used intravenous anesthetic agent, propofol, is not known. The goal of our current study is to examine the neurovascular protective effects of propofol on SAH-induced DCI. Twelve-week-old male wild-type mice were utilized for the study. Mice underwent endovascular perforation SAH or sham surgery followed one hour later by propofol infusion through the internal jugular vein (2 mg/kg/min continuous …
