Monkeypox in a Young Infant - Florida, 2022.

In August 2022, the Florida Department of Health (FDOH) was notified of a suspected case of monkeypox in an infant aged <2 months who was admitted to a Florida hospital with a rash and cellulitis. This case report highlights findings from the related epidemiologic investigation and describes the public health actions taken. This activity was reviewed by CDC and was conducted consistent with applicable federal law and CDC policy.

Evidence for pericyte origin of TSC-associated renal angiomyolipomas and implications for angiotensin receptor inhibition therapy.

Nearly all patients with tuberous sclerosis complex (TSC) develop renal angiomyolipomas, although the tumor cell of origin is unknown. We observed decreased renal angiomyolipoma development in patients with TSC2- polycystic kidney disease 1 deletion syndrome and hypertension that were treated from an early age with angiotensin-converting enzyme inhibitors or angiotensin receptor blockers compared with patients who did not receive this therapy. TSC-associated renal angiomyolipomas expressed ANG II type 1 receptors, platelet-derived growth factor receptor-β, desmin, α-smooth muscle actin, and VEGF receptor 2 but did not express the adipocyte marker S100 or the endothelial marker CD31.

Characterization of renal toxicity in mice administered the marine biotoxin domoic Acid.

Domoic acid (DA), an excitatory amino acid produced by diatoms belonging to the genus Pseudo-nitzschia, is a glutamate analog responsible for the neurologic condition referred to as amnesic shellfish poisoning. To date, the renal effects of DA have been underappreciated, although renal filtration is the primary route of systemic elimination and the kidney expresses ionotropic glutamate receptors. To characterize the renal effects of DA, we administered either a neurotoxic dose of DA or doses below the recognized limit of toxicity to adult Sv128/Black Swiss mice.

Sequential document visualization.

Documents and other categorical valued time series are often characterized by the frequencies of short range sequential patterns such as n-grams. This representation converts sequential data of varying lengths to high dimensional histogram vectors which are easily modeled by standard statistical models. Unfortunately, the histogram representation ignores most of the medium and long range sequential dependencies making it unsuitable for visualizing sequential data.

Progestin inhibition of cell death in human breast cancer cell lines.

Previously, we have shown that progestins both stimulate proliferation of the progesterone receptor (PR)-rich human breast cancer cell line T47D and protect from cell death, in charcoal-stripped serum-containing medium. To lessen the variability inherent in different preparations of serum, we decided to further characterize progestin inhibition of cell death using serum starvation to kill the cells, and find that progestins protect from serum-starvation-induced apoptosis in T47D cells. This effect exhibits specificity for progestins and is inhibited by the antiprogestin RU486.
