Mediterranean-style diet and intracranial large artery stenosis in the Northern Manhattan Study
Intracranial large artery stenosis (ICAS) is one of the most common causes of stroke worldwide.1 Among stroke-free community-dwelling adults, ICAS is prevalent, associated with modifiable vascular risk factors, and confers risk of incident vascular events.2 Given prior work linking a Mediterranean-style diet (MeDi), which is rich in fruits, vegetables, fish, whole grains, legumes, and nuts, to reduced risk of vascular conditions and cardiovascular events,3,4 we hypothesized MeDi may also be protective against ICAS.

Examining the subchronic (28-day) effects of aqueous Cd-BaP co-exposure on detoxification capacity and cardiac function in adult zebrafish (Danio rerio)
Aquat Toxicol. 2023 Aug 27;263:106672. doi: 10.1016/j.aquatox.2023.106672. Online ahead of print.ABSTRACTThe present study aimed to examine the effects of environmentally relevant concentrations of cadmium (Cd) and Benzo[a]Pyrene (BaP) in the adult zebrafish (Danio rerio). To this end, fish were exposed to either 1 or 10 μg/L Cd or 0.1 or 1 μg/L BaP in isolation, or a co-exposure containing a mixture of the two toxicants. Our results showed extensive modulation of the expression of key antioxidant genes (GPx, SOD1, catalase), detoxifying genes (MT1, MT2, CYP1A1) and a stress biomarker (HSP70) differing between control, s...

7 A.M.: COPELAND FARMS—ROCHELLE, GA
Just after dawn on a recent July day in Rochelle, Ga., Silvia Moreno Ayala steps into a pair of sturdy work pants, slips on a long-sleeved shirt, and slathers her face and hands with sunscreen. She drapes a flowered scarf over her wide-brimmed hat to protect her neck and back from the punishing rays of the sun. There isn’t much she can do about the humidity, however. Morning is supposed to be the coolest part of the day, but sweat is already pooling in her rubber boots.

7 Myths About Cholesterol, Debunked
You may not recall every lab value from your last physical, but you probably remember one: Your cholesterol level.
If it’s higher than ideal, you’re not alone. According to the U.S. Centers for Disease Control and Prevention, between 2015 and 2018, almost 12% of U.S. adults ages 20 and up had high total cholesterol, defined as above 240 mg/dL. The type that physicians mostly worry about is LDL (or “bad”) cholesterol, which is one component of that total.
Why do doctors care so much about cholesterol? First, “it predicts risk,” says Dr. Jeffrey Berger, a cardiologist and director of the C...

Prospective associations between diet quality, dietary components, and risk of cardiometabolic multimorbidity in older British men
ConclusionsOur study did not find a significant association of baseline EDI with CMM but showed that consuming more fish/seafood per week was associated with a lower risk of transition from FCMD to CMM in older British men.

What to Know About High Triglycerides
Discussions about heart health often center around blood pressure and cholesterol, with factors like poor sleep, smoking, family history of heart disease, and chronic stress thrown in. However, there’s one variable that doesn’t get covered as often, even though it can be an important indicator of cardiovascular risk: triglycerides.
“We don’t really talk about triglycerides very much, especially compared to cholesterol, but they’re actually an essential part of understanding heart health,” says Dr. Adriana Quinones-Camacho, a cardiologist at NYU Langone Health in New York. “For some...

Differences in Radiation-Induced Heart Dysfunction in Male Versus Female Rats
CONCLUSION: Together, these results illustrate that there are differences in radiation-induced cardiotoxicity between male and female SS rats and add to data that lung radiation doses may play an important role in cardiac dysfunction following heart radiation exposure. These factors may be important to factor into future mitigation studies of radiation-induced cardiotoxicity.PMID:36971580 | DOI:10.1080/09553002.2023.2194404

Straight from the heart: Mysterious lipids may predict cardiac problems better than cholesterol
Stephanie Blendermann, 65, had good reason to worry about heart disease. Three of her sisters died in their 40s or early 50s from heart attacks, and her father needed surgery to bypass clogged arteries. She also suffered from an autoimmune disorder that results in chronic inflammation and boosts the odds of developing cardiovascular illnesses. “I have an interesting medical chart,” says Blendermann, a real estate agent in Prior Lake, Minnesota.
Yet Blendermann’s routine lab results weren’t alarming. At checkups, her low-density lipoprotein (LDL), or “bad,” cholesterol hovered around the 100 milligrams-per-...

Up-regulation of lncRNA NEAT1 in cerebral ischemic stroke promotes activation of astrocytes by modulation of miR-488-3p/RAC1
Exp Brain Res. 2022 Dec 23. doi: 10.1007/s00221-022-06519-z. Online ahead of print.ABSTRACTWe aim to research the molecular mechanism of lncRNA NEAT1 in the activation of astrocytes in a cerebral ischemia-reperfusion injury model. Mouse model of cerebral ischemia-reperfusion injury was constructed, and shNEAT1 was transfected. The infarct area, brain water content, and neurological deficiency were detected. Immunofluorescence detection and fluorescence in situ hybridization (FISH) assay were processed to detect glial fibrillary acidic protein (GFAP) expression. Astrocyte cells were cultured for oxygen-glucose deprivation/r...
