Anticholinesterase and Antioxidant Potential of Hydromethanolic Extract of Ziziphus mucronata (Rhamnaceae) Leaves on Scopolamine-Induced Memory and Cognitive Dysfunctions in Mice.

Anticholinesterase and Antioxidant Potential of Hydromethanolic Extract of Ziziphus mucronata (Rhamnaceae) Leaves on Scopolamine-Induced Memory and Cognitive Dysfunctions in Mice. Evid Based Complement Alternat Med. 2019;2019:4568401 Authors: Foyet HS, Keugong Wado E, Ngatanko Abaissou HH, Assongalem EA, Eyong OK Abstract Ziziphus mucronata Willd, also known as "buffalo thorn," belongs to the family Rhamnaceae. Its bark and leaves are used in folk medicine for the treatment of various deficiencies related to nociception, inflammation, mood, and depression. Still, there is a lack of scientific data regarding its potential effect on learning and memory process. The present study was designed to investigate the neuroprotective potential of Ziziphus mucronata (ZM) on learning and memory impairment in a scopolamine-induced model of dementia in mice. The phytochemical analysis revealed five cyclopeptide alkaloids (sanjoinines) in the extract from Ziziphus Mucronata leaves using LC-HRMS, and the structural characterization of these compounds was determined via MS/MS. Alzheimer-type amnesia was induced by an intraperitoneal injection of scopolamine (1 mg/kg) to mice for 7 consecutive days. ZM (150 mg/kg, 300 mg/kg, and 600 mg/kg) and piracetam (150 mg/kg) were orally administrated to mice daily for a period of 14 days. Memory-related behavioural parameters were evaluated using the radial arm maze task for 7 days, Y-maz...

“Get out! Get out!” My wife, Joan, having just woken up, was screaming, and hitting out wildly at the stranger in her bed. She was in a panic, her body shaking with fright. “Get away from here. Get out!” The man she perceived as a stranger was me, her husband of more than forty years. Joan was eight years into the destructive course of atypical early-onset Alzheimer’s disease, a horrific disorder that ravaged her, leaving her blind and with serious dementia. At that moment, she was experiencing something called Capgras Syndrome, in which patients become deluded that those close to them and the...

“In my case, symptoms began to appear when I was only 57. In fact, the doctors believe early-onset Alzheimer’s has a strong genetic predictor, and that it may have been progressing for some years before I was diagnosed.” – Pat Summitt  Anyone who’s gone through the experience of a loved one developing Alzheimer’s disease and progressively deteriorating to a shell of their former selves knows how devastating this brain disease is for both patient and those who love and care for him or her.  Memory Performance Changes May Show Up in 20s with Family History of Alzheimer’s St...

There are a number of things that can increase the risk of dementia: age, of course, as well as certain genetic profiles and behaviors such as smoking and drinking. Some of the same things that contribute to heart disease, such as high cholesterol levels and the build up of plaques in the blood vessels, can also boost the chances of developing dementia. And in a large study published in JAMA Internal Medicine conducted in the UK, researchers report another possible factor: a group of drugs known as anticholinergics. These include prescription medications for treating depression, pulmonary disease, and Parkinson’s, as...

This study shows that mRNA levels of the aging related lamin A splice variant progerin, associated with premature aging in HGPS, were significantly upregulated in subjects with BMI ≥ 25 kg/m2. Moreover, our data revealed a significantly positive correlation of BMI with progerin mRNA. These data provide to our knowledge for the first-time evidence for a possible involvement of progerin in previously observed accelerated aging of overweight and obese individuals potentially limiting their longevity. Our results also showed that progerin mRNA was positively correlated with C-reactive protein (CRP). This might suggest an as...

CNN) — After examining the brains of former professional football players, researchers might be a step closer to diagnosing the devastating brain disease chronic traumatic encephalopathy in the living, according to a study published Wednesday in the New England Journal of Medicine. The researchers utilized PET imaging to find tau, an abnormal protein that’s a signature indicator of CTE, using a radioactive drug or tracer called flortaucipir. The researchers imaged the brains of 26 living former football players and compared them with the brains of 31 people with no history of traumatic brain injury. (WBZ-TV) Th...

In this study, we show that calorie restriction is protective against age-related increases in senescence and microglia activation and pro-inflammatory cytokine expression in an animal model of aging. Further, these protective effects mitigated age-related decline in neuroblast and neuronal production, and enhanced olfactory memory performance, a behavioral index of neurogenesis in the SVZ. Our results support the concept that calorie restriction might be an effective anti-aging intervention in the context of healthy brain aging.
