Atypical' form of mad cow disease confirmed in Alabama cow

If you eat beef from grass fed animals you don't need to worry about BSE.

It's about time we learned that nature does things in a certain way for a very good reason.

The average age to cut a breeding cow is 8 to 9 I think if what I recall is correct, so 11 is old. But 8 to 9 is only the average. From what I see, a lot of young cows also get cut because they simply don't have the capacity to produce a calf every year. For some herds, it doesn't make sense to keep them as breeders because the "cash crop" is the calves they produce. So if the average age is 8 to 9, and part of that average is skewed by the young cows how won't be every year producers ... that means there are a decent number of older cows too to pull that average up.

The problem I had with this was the 11 year old part...Unless I miss my guess , that is a lot old for beef cattle.

Usually MCdon's or another huge restaurant chain buys anything standing to grind.

Does McDonald's or any other buy it directly ? or purchase through a distributor ?
I dont usually make blanket statements without knowing
I know the answer to my question , do you ?

I have been to actions in Michigan and the buyer for the supplier for the big burger corps were there. And they did indeed buy anything standing.

I guess a supplier is not technically Mcdon. Perhaps a permanent contractor would have been more accurate.

You don't have to worry about this cow's acute disease. It happen naturally, supposedly.

Let me rephrase, this cow was inches from being sold, it happened to be seen by observers or surveillance if you will. The farmer had no idea it was sick or it would not have been at the market, supposedly.

If the surveillance was not in place guess what would have happened.

Something does not add up.

After my daughter was born in 1993, I took a job in Organ/Tissue recovery. Plastered ALL over the exam rooms, operating rooms, morgue, etc were signs waring about using extreme precautions because of BSE. It is easily spread and a VERY scary disease in humans. I wondered, as I was reading the article about the cow found to have it, how many cows got THROUGH? DANG scary to think about.....a reply to: seasonal

I use medical MJ for my neurological disease: epilepsy. I used to work in operating rooms and with dead bodies when I worked Tissue and Organ recovery...I do not think CBD would protect against these prions. My epilepsy is caused by repeated concussions.....in the study you site...I believe it is referring more to things like Alzheimers, dementia, MS, Parkinsons, seizures, etc.....BSE or mad cow is a SCARY disease.....it was ALL over the news in the 1990's and there were signs posted ALL over exam rooms, operating rooms, morgues, etc..... reply to: M4ngo

So that explains the people of Alabama....

The scary part is that we don't know if the other cattle were infected from the original farm.
Chances are they were.
This is an example of our tax dollars at work against us.
It also makes me wonder if Soros has a hidden investment in here somewhere.

Wake up.

Mad cow disease = prions

Cannabinoids protect you from getting neurodegenerative disease in the first place. Including, from prions, like in MCD.

Our results suggest that CBD may protect neurons against the multiple molecular and cellular factors involved in the different steps of the neurodegenerative process, which takes place during prion infection. When combined with its ability to target the brain and its lack of toxic side effects, CBD may represent a promising new anti-prion drug.

Nonpsychoactive Cannabidiol Prevents Prion Accumulation and Protects Neurons against Prion Toxicity

This is an impressive study. And I must say, an excellent discovery on your part. Star 4 U !!!

However:
"During the time course of these experiments, no significant side effects were seen in noninfected, CBD-treated mice (data not shown). In summary, our data demonstrate that, when applied the day of infection or as late as 1 month after infection, CBD slows down PrPres accumulation in the brains of prion-infected mice and delays the onset of terminal prion disease."
This is an important direction for research to follow (or maybe they already know).
Perhaps farmers should start growing some weed for livestock ingestion.

I think CBD would most definitely protect the brain from these prions.

In the brains of CBD-treated mice, PrPres was barely detectable, whereas substantial amounts of PrPres were present in the brain of presymptomatic untreated control mice (Fig. 2A, top).

To determine whether CBD could affect prion disease in vivo, we infected wild-type mice (Fig. 1 D) by intraperitoneal inoculation with a high dose of 139A murine scrapie strain. This strain was chosen because its incubation period after peripheral inoculation is shorter and less variable than other strains (Carp et al., 1997). Starting on the day of infection (0 dpi) and continuing three times per week over a 4 week period, mice were treated with 20 mg/kg CBD. Treatment with CBD significantly increased the survival time of the infected wild-type mice compared with the vehicle-treated group ( p 0.02, Mann–Whitney test). Treatment over a longer period of time (up to 12 weeks) or treatment with a higher dose of CBD (60 mg/kg over 4 weeks) also led to a significant increase in the survival time of infected mice ( p 0.003 and 0.0003, respectively). To determine whether CBD also inhibited prion disease progression during the later stages of infection, we began treatment of infected mice at either 30 or 120 dpi. When 20 mg/kg CBD treatment was initiated at 30 dpi, the survival time of mice was significantly increased compared with the vehicle-treated group ( p 0.03). However, no significant difference was observed when CBD treatment was started at 120 dpi (data not shown). Overall, CBD delayed prion disease onset in scrapie-infected mice in a time- and concentration-dependent manner.

When treatment was applied starting the day of infection, CBD significantly delayed both the appearance of clinical signs of the disease (delay, 5.7 d; p 0.021) and death (delay, 5.4 d; p 0.022) compared with the vehicle-treated group. When CBD treatment started at 30 dpi (approximately one-third of the incubation time), no significant delay in the progression of the disease was observed. During the time course of these experiments, no significant side effects were seen in noninfected, CBD-treated mice (data not shown). In summary, our data demonstrate that, when applied the day of infection or as late as 1 month after infection, CBD slows down PrPres accumulation in the brains of prion-infected mice and delays the onset of terminal prion disease.

The addition of CBD appeared to decrease PrPres-induced neurotoxicity because the number and morphology of the neurons was similar to that observed in cells exposed to hgtsc (Fig. 5A). Neuronal viability was also monitored by mea- suring the reduction in mitochondrial activity using the MTS assay. CBD treatment resulted in a concentration-dependent in- crease in the number of viable neurons for both concentrations of hgtsc tested (Fig. 5B).

Because CBD has been
shown to regulate microglia migration (Walter et al., 2003), it was of interest to determine whether or not CBD could affect this PrPres-induced chemotactic mechanism. The migration of N11 microglia toward a chamber containing neurons incubated with PBS, hgtsc or hgtsc was monitored in the presence of increasing concentrations of CBD (Fig. 5C). Hgtsc -exposed neurons induced an increase in the number of migrating microglia compared with hgtsc and PBS- exposed neurons. Importantly, no effect on the basal migration rate of microglial cells was observed with CBD alone, indicating that CBD by itself does not have in vitro chemotactic properties (Fig. 5C). Thus, CBD was able to impair PrPres-induced microglial cell migration in a concentration-dependent manner.

Here, we demonstrate that CBD increases the survival time of scrapie-infected mice, most likely by preventing cerebral accumulation of PrPres. Given that CBD inhibited PrPres accumulation in cells infected with both murine and sheep scrapie strains, it is likely that it will be effective against different TSE agents in different species.

Unexpectedly, we demonstrated that CBD does not inhibit PrPres formation in a cell-free assay in which the primary components are PrPsen and PrPres. It is therefore unlikely that CBD binds PrP isoforms. Rather, CBD may exert its anti-prion properties indirectly via more complicated cellular mechanisms that may be cell-type specific. The fact that inhibition of PrPres accumulation by CBD in scrapie-infected cells is slow, requiring passage of the cells several times in the presence of the drug to see an effect, is consistent with this idea.

Moreover, the idea of a mechanism of inhibition common to some cell types but not others is supported by the finding that CBD prevents PrPres formation in the brain, but not the spleen, of scrapie-infected mice. Alternatively, CBD may also hamper neuroinvasion from the periphery to the CNS. In this instance, because of its high lipophilicity, CBD could interact with neuronal cell membranes leading to membrane mod- ifications unfavorable to PrPres formation

Interestingly, it has recently been shown that cannabinoids prevent Alzheimer’s disease pathology via the blockade of microglial activation (Ramirez et al., 2005). Similarly, we demonstrated here that CBD protected neurons against PrPres toxicity and prevented PrPres-induced microglial cell migration. Thus, CBD may modulate glial cell function, leading to a reduction in the inflammatory response that usually accompanies neurodegeneration.

Together, our results suggest that CBD has the properties necessary to protect neurons against the multiple molecular and cellular factors involved in the different steps of the neurodegenerative processes that take place during TSE infection.

... the sick animal was discovered during routine surveillance at an Alabama livestock market. The animal died at the market before entering the slaughter channels and samples were sent to a USDA lab in Iowa for confirmation.

This statement is confusing. Was the sick cow discovered when it died just before entering slaughter? Or, it was discovered and then it died just before it went to slaughter? If the latter, did they let it continue on it's journey knowing it was sick?

Inquiring minds want to know
