Thirty-six-week-old again female C5BL/6 mice were injected with MSM for thirteen weeks. Researchers examined the effects of MSM on bone density and development using micro-computed tomographic images, serum analyses, and immunohistochemical analyses.

The research associated with this dataset explored cross-species prion transmission and the impact of cofactor environment on strain adaptation. Utilizing Protein Misfolding Cyclic Amplification with beads (PMCAb), hamster strain 263K was propagated under normal or RNA-depleted conditions first in mouse and then hamster substrates. A variety of readaptation experiments were conducted including brain analysis of hamsters inoculated with different PMCAb-derived material. Dataset includes Western blot and comparative histopathological brain images.

A high glucose level associated with maternal diabetes has been identified as a risk factor for fetal neural tube defects (NTD). The failure to successfully complete the complex neurulation process is possibly related to the loss of protection for cellular homeostasis resulting in organelle stress. Mitochondrial dysfunction and endoplasmic reticulum stress in the developing endothelium have been identified as significant components in diabetic embryopathy. Myristoylated Alanine-Rich C Kinase Substrate (MARCKS) is a critical protein involved in fetal neural development. This study investigated the regulation and biological activity of MARCKS and its role in protecting neuroepithelial cell organelles during neurulation. Furthermore, the effects of the acetylation/phosphorylation/deacetylation of MARCKs by Tip60 and sirtuin 2 were examined with respect to the protein’s protective functionality. The dataset includes immunoblot/immunofluorescent/electronmicroscopy images and graphs.

Chronic neuroinflammation is a common pathological hallmark of neurodegenerative diseases such as Alzheimer’s, Parkinson’s, ALS, and prion disorders. Both reactive microgliosis and astrogliosis have been identified as having a role in the neuroinflammatory process. Studies of prion diseases of animals and humans have demonstrated activation and proliferation of microglia at the very early subclinical stages. Less is known about the role of reactive astrocytes. This research investigated the changes in normal functions of astrocytes over the course of chronic neuroinflammation including their region-specific responses in the brain. Studies of brain tissue of mice infected with 22L mouse-adapted prion strain include histological, immunofluorescence, and qRT-PCR. Prion deposition and reactive microgliosis and astrogliosis were examined across regions of the whole brain with particular focus on the thalamus and hippocampus.

Nonarthritic anterior ischemic optic neuropathy (NAION) commonly causes sudden optic nerve (ON)-related vision loss. The rodent NAION model (rAION) closely resembles NAION in presentation and physiological responses. Researchers hypothesized that blocking pro-inflammatory prostaglandin (PGE2) production by inhibiting monoacylglycerol lipase or cyclooxygenase activity and co-administering PGJ2 would potentiate RGC survival following ischemic neuropathy. This study identified early rAION-associated optic nerve head (ONH) inflammatory gene expression responses and the anti-inflammatory prostaglandin PGJ2’s effects on those responses. Deep sequencing was performed on vehicle- and PGJ2-treated ONHs 3d post-rAION induction. Results were compared against responses from a retinal ischemia model. Animals were treated with PGJ2 and MAGL inhibitor KML29, or PGJ2 + COX inhibitor meloxicam. RGC survival was quantified by stereology.

The rodent model of nonarthritic anterior ischemic optic neuropathy (rNAION) is similar in many of its pathophysiological responses to clinical NAION. Like human NAION, there is significant variability in the severity of the lesion produced, and little is known of the parameters associated with rNAION induction severity or if pre- or early post-induction biomarkers can be identified that enable prediction of lesion severity and ultimate loss of retinal ganglion cells (RGCs). Adult male Sprague-Dawley outbred rats were evaluated for various parameters including physiological characteristics (heart rate, respiratory rate, temperature, hematocrit [Hct]), optic nerve head (ONH) appearance, pre- and post-induction mean diameter, and intravenous fluorescein and indocyanine green angiographic patterns of vascular leakage at 5 hours post-induction, performed using a spectral domain-optical coherence tomography (SD-OCT) instrument.

Researchers present an optimized protocol for single nuclei RNA sequencing (snRNA-seq) that is fast, low, cost, and time effective due to the elimination of cell sorting and ultra-centrifugation. Both human and mouse tissue biopsies were assessed. Human kidney graft biopsies were collected from five kidney transplant recipients. Mouse needle biopsies were collected from heart, liver, kidney, spleen, lung, duodenum, large intestine, bone marrow and brain.

Non-typhoidal Salmonella (NTS) is responsible for approximately 93 million cases of gastroenteritis annually. Little research has been directed towards a development of vaccines against Salmonella serogroups O:6,7 or O:8. Researchers constructed a live attenuated serogroup O:8 vaccine, CVS 1979, by deleting guaBA, htrA, and aroA from the genome of S. Newport. Over the course of 6 weeks, 6 to 8-week-old female BALB/c mice were immunized with live attenuated S. Newport vaccine CVD 1979 or sterile phosphate buffered saline (PBS) three times. Four weeks after the last immunization, mice were challenged intraperitoneally (i.p.) with wild-type Salmonella strains to assess the homologous and heterologous protection elicited by the live attenuated S. Newport vaccine CVD 1979.

Tissue from the optic nerve lamina region (ONLR), were dissected from both mice and humans. Immunohistochemistry (IHC) was then performed on tissue sections, and Ki67 mitosis assays assessed cell proliferation. Cell cultivation techniques isolated and cultured cells from ONLR and optic nerve tissues. Further experiments induced cell differentiation and neurosphere formation. Transgenic animal studies explored gene effects, while interventions included AAV-DTA construct injections and TAM/4OHT treatments. RNA isolation and qPCR analyzed gene expression, while imaging techniques visualized tissue morphology and axonal myelination.

Thirty-five Yorkshire cross swine underwent percutaneous myocardial infarction with ethanol ablation of the circumflex or obtuse marginal (OM) arteries. Echocardiography was performed at various intervals to assess the development of ischemic mitral regurgitation (IMR) and cardiac function. Swine that developed significant IMR were scheduled for mitral valve operations, which were performed using cardiopulmonary bypass. Echocardiographic analysis was conducted to evaluate parameters such as ejection fraction, mitral regurgitation severity, and wall motion.
