Reservoir‐Type Subcutaneous Implantable Devices Containing Porous Rate Controlling Membranes for Sustained Delivery of Risperidone

Advanced Healthcare Materials, EarlyView.
This study presents a novel implantable drug delivery systemwith a biodegradable poly(caprolactone) membrane and compressed drug core forsustained release. These implantable devices deliver risperidone in vitro for 170 days and in vivo for 49 days in rats, showing promise for chronic conditions like schizophrenia.

Induction of tier-2 neutralizing antibodies in mice with a DNA-encoded HIV envelope native like trimer

Nature Communications, 2022
HIV envelope is a target for vaccine development, but induction of broadly neutralizing antibodies has been difficult. Here, the authors show that electroporation with a synthetic DNA vaccine construct allows in vivo production of HIV envelope native ...

Decitabine disrupts EBV genomic epiallele DNA methylation patterns around CTCF binding sites to increase chromatin accessibility and lytic transcription in gastric cancer

mBio, 2023
Epstein-Barr virus (EBV) is associated with 10% of human gastric carcinomas, which are distinguished by a CpG island methylator phenotype. In gastric carcinoma tumors and cell lines, the EBV genome also exhibits a high degree of 5-methyl cytosine (5mC ...

Permeation Enhancer‐based Ionogel Shows Remarkable Potential for Oral Insulin Delivery

Advanced Healthcare Materials, EarlyView.
This study proposes a novel formulation of decanoate in an ionic liquid inspired drug delivery system. The formulation demonstrates ideal physicochemical and material properties for oral peptide delivery. Findings indicate that choline decanoate (1:2 molar ratio) forms a viscoelastic gel that enables high oral bioavailability of insulin in rats ...

Gastroparesis and lipid metabolism-associated dysbiosis in Wistar-Kyoto rats

American Journal of Physiology - Gastrointestinal and Liver Physiology, 2017
This study reveals that the stress-prone Wistar-Kyoto rat strain has a baseline physiology of gastroparesis and rapid small intestine transit, together with metabolic changes consistent with lipid metabolism-associated dysbiosis, compared with nonstress ...

Automated Transcranial Photobiomodulation in Healthy Rats: Effects on Working Memory and Brain Markers

Advanced Therapeutics, EarlyView.
Transcranial photobiomodulation (PBM) enhances spatial working memory in healthy rats under both continuous and alternating stimulation protocols. At the neural level, PBM modulates cytochrome c oxidase activity, increases prefrontal and hippocampal synaptic markers, and induces region‐specific c‐Fos expression. These effects suggest improved cognitive

Can Viruses be Modified to Achieve Sustained Gene Transfer?

Frontiers in Microbiology, 2011
It is very easy to replace a faulty gene in an immunocompromised mouse. First, one takes a well-characterized virus, such as an adenovirus or an adeno-associated virus, and incorporates the correct version of the faulty gene together with some regulatory

Non‐Invasive Diagnosis of Chronic Myocardial Infarction via Composite In‐Silico‐Human Data Learning

Advanced Science, EarlyView.
This study presents a non‐invasive machine learning model to identify infarct regions in the left ventricle using cardiac strain data. By combining rodent‐based simulated data with limited human data, the model achieves high accuracy in predicting infarct size and location without the need for gadolinium contrast agents, offering a promising ...
