Nicotine remains a major cause of health problems in the US and around the world. Insight into the behavioral changes induced by nicotine use may help advance the understanding of the mechanisms underlying the maintenance of nicotine addiction and thus the important factors involved in the quitting process. Pavlovian bias is a phenomenon that includes an approach tendency toward rewarding cues and an action withdrawal tendency in response to punishments. This phenomenon may be particularly relevant to nicotine users. The current study will use an experimental, within-subjects, repeated-measured design to investigate whether acute nicotine administration influences individual Pavlovian bias in nicotine users. By recruiting participants from the University of Southern California (USC) community and contacting participants of previous nicotine-related studies of the Addiction and Self-Control Laboratory at USC, the investigators will enroll forty adult nicotine users in the study. Participants will come to the lab twice after a 10-hour nicotine fast. At each lab visit, participants will undergo a vaping session prior to completing the study tasks. The content of the e-liquid in the vape will vary by nicotine content: the vape will either contain nicotine or not. Subsequent to vaping, participants will complete a version of the Go/No-Go task which will measure their individual levels of Pavlovian bias. The investigators will compare performance on the task across the two conditions within each participant: on- and off- nicotine, after controlling for nicotine withdrawal and nicotine tolerance. Based on past research on nicotine, the researchers anticipate that acute nicotine administration will be associated with higher levels of Pavlovian bias, compared to the off-nicotine condition. Specifically, two patterns are expected to arise: a higher likelihood of making a go-response in the "win reward" condition and a higher likelihood of making a no-go response in the "avoid losing" condition, regardless of whether it is a "go" or "no-go" trial. Participants will also complete a measure of their working memory capacity. The investigators will conduct exploratory analyses for the relationship between different nicotine conditions and working memory capacity. Read Less

The investigators have successfully identified two novel genetic loci for MVP on chromosomes 11 and 13 and are searching for altered genes in these regions. This requires recruiting large families who may have MVP linked to these or other chromosomes; and obtaining DNA samples from 1,000-1,500 individually affected patients to study the relation between DNA markers throughout the genome and MVP. It is our expectation that the results of this study will lead to the discovery of gene(s) responsible for MVP. This will lead to improved understanding of the disease and, in turn, improved ability to treat and prevent progression in genetically susceptible individuals. Read Less

Primary brain tumors are typically treated by surgery, radiation therapy and chemotherapy, either individually or in combination. Present therapies are inadequate, as evidenced by the low 5-year survival rate for brain cancer patients, with median survival at approximately 12 months. Glioma is the most common form of primary brain cancer, afflicting approximately 7,000 patients in the United States each year. These highly malignant cancers remain a significant unmet clinical need in oncology. GBM often has a high expression of EFGR (Epidermal Growth Factor Receptor), which is associated with poor prognosis. Several methods of inhibiting this receptor have been tested, including monoclonal antibodies, vaccines, and tyrosine kinase inhibitors. The investigators hypothesize that in patients with recurring GBM, intracranial superselective intra-arterial infusion of Cetuximab (CTX), at a dose of 250mg/m2 in conjunction with hypofractionated radiation, will be safe and efficacious and prevent tumor progression in patients with recurrent, residual GBM.

The purpose of this study is to evaluate the safety and efficacy of administering the medication capecitabine along with temozolomide when you start your monthly regimen of oral temozolomide for the treatment of your newly diagnosed glioblastoma multiforme (GBM). Capecitabine is an oral chemotherapy that is given to patients with other types of cancer. The study will evaluate whether the dosage of 1500 mg/m2 of capecitabine is tolerable after radiation, when taken along with temozolomide. It will also try to determine if the medication capecitabine helps patients respond to treatment for a longer period of time compared to just temozolomide alone, which is the standard of care.

The NanoSense study is a multi-center, prospective, non-randomized, observational, feasibility, non-significant risk study. The NanoSense study will enroll up to 500 subjects in up to 10 centers in order to collect data which includes at least 150 heart failure hospitalizations in participating subjects.The duration of the NanoSense study is expected to be 2 years. The study device is the Wearable Congestive Heart Failure Management System (WCHFS, also known as SimpleSENSE) Read Less

The NanoCOAT study is a multi-center, prospective, non-randomized, feasibility, observational, non-significant risk study. The NanoCOAT study will enroll a minimum of 10 and a maximum of 100 subjects in a potential for a multi-site in order to collect data and analyze physiological and biometric trends due to Covid-19.

The objective of this study is to evaluate an experience of post-operative monitoring using the Nanowear wearable multiple sensor vest in plastic surgery Read Less

The goal of the project is to evaluate whether donepezil + cognitive remediation therapy is superior to placebo in reducing heavy drinking in patients with alcohol use disorder in a double-blind, placebo-controlled trial. Read Less

The present study will investigate a set of biomedical sensors with a wireless data communication system and evaluate the sensors' recording quality. The sensors and wearable wireless system have been approved by Food and Drug Administration (FDA) for recording Electrocardiography (ECG), Trans Thoracic Impedance (TTI), Heart Sounds and Acitigraphy. The sensors and wireless system will be used along with conventional sensor systems (as intended to be used). Read Less

The Nanowear SimpleSense study is a single center, prospective, non-randomized, feasibility, non- significant risk study The study will be done in 2 phases. Phase 1 will use SimpleSense data collected from the first set of subjects and associate the data from SimpleSense to the right heart catheterization values.' Phase 2 will evaluate the algorithms developed to estimate cardiac output from SimpleSense data using a second set of subjects from within the sample population that are sequestered from the first set used for association of data from SimpleSense to the data from the right heart catheterization.
