Controlled Ice Nucleation With a Sand-PDMS Film Device Enhances Cryopreservation of Mouse Preantral Ovarian Follicles.

J Med Device

December 2024

Fischell Department of Bioengineering, University of Maryland, College Park, MD 20742; Robert E. Fischell Institute for Biomedical Devices, University of Maryland, College Park, MD 20742; Marlene and Stewart Greenebaum Comprehensive Cancer Center, University of Maryland, Baltimore, MD 21201.

Ovarian follicle cryopreservation is a promising strategy for fertility preservation; however, cryopreservation protocols have room for improvement to maximize post-thaw follicle viability and quality. Current slow-freezing protocols use either manual ice-seeding in combination with expensive programmable-rate freezers or other clinically incompatible ice initiators to control the ice-seeding temperature in the extracellular solution, a critical parameter that impacts post-cryopreservation cell/tissue quality. Previously, sand has been shown to be an excellent, biocompatible ice initiator, and its use in cryopreservation of human induced pluripotent stem cells enables high cell viability and quality after cryopreservation.

Environ Pollut

December 2024

Department of Medicine Cardiology Division, University of Maryland School of Medicine, Baltimore, MD, 21201, USA. Electronic address:

Maternal exposure to particulate matter with an aerodynamic diameter ≤2.5 μm (PM) is believed to be a risk factor of developmental origins of health and disease (DOHaD), but its effect on offspring's susceptibility to obesity, a common target disease of DOHaD, remains controversial. To pinpoint the effect of maternal PM exposure on offspring's energy homeostasis, female C57BL/6J mice were exposed to filtered air (FA) or concentrated ambient PM (CAP) for 12 weeks and mated with normal male mice to produce offspring.

Routine chest CT is not essential for the diagnostic workup for infective endocarditis (IE), but this type of study may be the initial imaging modality in the evaluation of patients ultimately proven to have IE who present to the emergency department with nonspecific clinical symptoms. Although routine chest CT cannot directly assess valvular oscillating motion due to the lack of cine images, we hypothesized that a combination of elongated nodular valve thickening and abnormal orientation to the normal valve with a blind end on routine CT (indirect-oscillation sign) might suggest movable vegetation indirectly. To evaluate this possibility, we studied 27 patients with IE and 35 controls who underwent both routine chest CT and echocardiography.

Bazedoxifene as a Potential Cancer Therapeutic Agent Targeting IL-6/GP130 Signaling.

Curr Oncol

September 2024

Department of Biochemistry and Molecular Biology, School of Medicine, University of Maryland, Baltimore, MD 21201, USA.

Targeting the interleukin-6 (IL-6)/glycoprotein 130 (GP130) signaling pathway holds significant promise for cancer therapy given its essential role in the survival and progression of various cancer types. We have identified that bazedoxifene (BZA), a Food and Drug Administration (FDA)-approved drug used for the prevention of postmenopausal osteoporosis, when combined with conjugated estrogens in Duavee, also has a novel function as an inhibitor of IL-6/GP130 interaction. BZA is currently under investigation for its potential anticancer therapeutic function through the inhibition of the IL-6/GP130 pathway.

Background: Patients with severe stroke are at high risk of secondary neurologic decline (ND) from the development of malignant cerebral edema (MCE). However, early infarcts are hard to diagnose on conventional head computed tomography (CT). We hypothesize that high-energy (190 keV) virtual monochromatic imaging (VMI) from dual-energy CT (DECT) imaging enables earlier detection of ND from MCE.

Reassessment of capsaicin desensitization in the rodent spinal dorsal horn.

Neurochem Int

December 2024

Department of Anatomy, Histology and Embryology, K.K. Leung Brain Research Centre, The Fourth Military Medical University, Xi'an, Shaanxi, 710032, China. Electronic address:

Capsaicin activates primary afferent transient receptor potential vanilloid 1 (TRPV1) in the spinal dorsal horn and induces exaggerated glutamate release. This capsaicin action is followed by a lasting refractory state referred to as "capsaicin desensitization", which is considered a presynaptic event. In this study, using whole-cell recordings and holographic photostimulation, we reassessed this notion by investigating presynaptic glutamate release and the postsynaptic glutamate response during capsaicin administration.

A hollow fiber membrane (HFM) was previously characterized as a potential permeation component of a dissolution/permeation system. Two objectives were to assess the impact of micellization on drug permeation across HFM and identify a preferred permeation model from three models: permeation from only free drug, permeation from both free drug and micelle-bound drug, and permeation with enhancement from micelle shuttling. HFM studies were conducted under unsaturated drug conditions, using griseofulvin and the more hydrophilic drug meloxicam, with and without surfactant [sodium lauryl sulfate, polysorbate 80, and polyoxyethylene (10) lauryl ether].

Center for Biomedical Engineering and Technology, University Hospital Basel, University of Basel, Basel, Switzerland; Department of Biochemistry and Molecular Biology, University Hospital Basel, University of Basel, Basel, Switzerland; Department of Physiology, University of Maryland School of Medicine, Baltimore, MD 21201, USA. Electronic address:

We report that the outer mitochondrial membrane (OMM)-associated E3 Ub ligase MARCH5 is vital for generating mitochondria-derived pre-peroxisomes. In human immortalized cells, MARCH5 knockout leads to the accumulation of immature peroxisomes, reduced fatty-acid-induced peroxisomal biogenesis, and abnormal peroxisome biogenesis in MARCH5/Pex14 and MARCH5/Pex3 dko cells. Upon fatty-acid-induced peroxisomal biogenesis, MARCH5 redistributes to peroxisomes, and ubiquitination activity-deficient mutants of MARCH5 accumulate on peroxisomes containing high levels of the OMM protein Tom20 (mitochondria-derived pre-peroxisomes).
