COVID-19 in Cancer Patients From New York City: A Comparative Single Center Retrospective Analysis.

In this retrospective study we analyze and compare clinical characteristics and outcomes of patients with and without cancer history who were infected with novel coronavirus disease 19 (COVID-19). Medical records were reviewed and a comparative analysis of 53 cancer and 135 non-cancer patients with COVID-19 were summarized. Results: The median age for COVID-19 patients with and without cancer was 71.

Low morbidity and mortality with COVID-19 in sickle cell disease: A single center experience.

Coronavirus disease 2019 (COVID-19) is caused by SARS-CoV-2 infection, which evolved into a global pandemic within a short time. Individuals with sickle cell disease (SCD) suffer from underlying cardiopulmonary comorbidities and are at risk of severe complications such as pneumonia, acute chest syndrome, thrombosis, stroke, and multiorgan failure. Whether COVID-19 poses a high risk of morbidity and mortality in SCD patients remains unclear.

Surface-Modified G4 PAMAM Dendrimers Cross the Blood-Brain Barrier Following Multiple Tail-Vein Injections in C57BL/6J Mice.

Intracranial injections are currently used to deliver drugs into the brain, as most drugs cannot cross the blood-brain barrier (BBB) following systemic injections. Moreover, multiple dosing is difficult with invasive techniques. Therefore, viable systemic techniques are necessary to facilitate treatment paradigms that require multiple dosing of therapeutics across the BBB.

Molecular, cellular and functional events in axonal sprouting after stroke.

Stroke is the leading cause of adult disability. Yet there is a limited degree of recovery in this disease. One of the mechanisms of recovery is the formation of new connections in the brain and spinal cord after stroke: post-stroke axonal sprouting.

Intracerebral hemorrhage in mouse models: therapeutic interventions and functional recovery.

There has been strong pre-clinical research on mechanisms of initial cell death and tissue injury in intracerebral hemorrhage (ICH). This data has led to the evaluation of several therapeutics for neuroprotection or the mitigation of early tissue damage. Most of these studies have been done in the rat.

Effects of lentivirus-mediated CREB expression in the dorsolateral striatum: memory enhancement and evidence for competitive and cooperative interactions with the hippocampus.

Neural systems specialized for memory may interact during memory formation or recall, and the results of interactions are important determinants of how systems control behavioral output. In two experiments, we used lentivirus-mediated expression of the transcription factor CREB (LV-CREB) to test if localized manipulations of cellular plasticity influence interactions between the hippocampus and dorsolateral striatum. In Experiment 1, we tested the hypothesis that infusion of LV-CREB in the dorsolateral striatum facilitates memory for response learning, and impairs memory for place learning.

Lentivirus-mediated chronic expression of dominant-negative CREB in the dorsal hippocampus impairs memory for place learning and contextual fear conditioning.

Extensive research has shown that the transcription factor CREB has an important role during memory formation. In the present study, we tested a new method for chronic, stable expression of a dominant-negative form of CREB (mCREB) in the dorsal hippocampus using lentiviral vectors. In specific, we tested whether lentivirus-mediated chronic expression of mutant CREB impairs memory for two hippocampus-dependent tasks - place training in the water maze and contextual fear conditioning.
