HOW TO DETERMINE PCV (PACKED CELL VOLUME)

The Packed Cell Volume (PCV) Test 1. Objective: This is one of the oldest tests done in medical practice. The objective of this test was to determine the percentage of red blood cells (RBCs) in whole blood. It  also helped to assess the blood’s capacity to carry oxygen. ________________________________________ 2. Principle: The test was based on the principle that when blood was centrifuged, the red blood cells settled at the bottom of the tube, forming a packed column. The ratio of the packed RBC column to the total blood column gave the packed cell volume (PCV), expressed as a percentage. ________________________________________ 3. Materials: • Microhematocrit capillary tubes • Microhematocrit centrifuge • Plasticine or sealing clay • Microhematocrit reader • Lancet • Alcohol swab • Cotton ________________________________________ 4. Procedure (Microhematocrit Method): 1. The fingertip was cleaned with an alcohol swab and pricked with a sterile lancet. 2. Blood was collected into ...

COULD THIS BE A CURE FOR CANCERS?

COULD THIS BE A CURE FOR CANCERS?

DOSTARLIMAB CURES ALL PATIENTS IN DRUG TRIAL FOR THE FIRST TIME EVER


A cancer cell about to split


Recent reports have it that for the first time in history, a drug under testing has managed to completely remove every trace of cancer in patients partaking in the drug trial.


The course of therapy was estimated to be six months long, involving a total of 18 patients, all diagnosed with rectal cancer and by the end of the program every one of them, on testing, had no trace of rectal cancer in them.


After six months or more of follow-up, the patients continued to show no signs of cancer — without the need for the standard treatments of surgery, radiation, and chemotherapy — and cancer has not returned in any of the patients, who have now been cancer-free for a range of six to 25 months after the trial ended.



This is truly remarkable feet and applauds are raining down on researchers at the Memorial Sloan Kettering Cancer Center where the research was carried out


Dostarlimab is a programmed death receptor-1 (PD-1)–blocking monoclonal antibodies.


This new treatment is a type of immunotherapy, a treatment that blocks the 'don't eat me' signal on cancer cells enabling the immune system to eliminate them.


The immunotherapy treatment with dostarlimab targets a subtype of rectal cancer that has the DNA repair system not working. When this system isn't working there are more errors in proteins and the immune system recognizes these and kills the cancer cells.


This Dostarlimab was approved for medical use in the United States (US) and the European Union (EU) in April 2021.


Before this day, Dostarlimab was used to treat cancer of the uterus lining (endometrial cancer). This medication is also used to treat certain types of tumors (solid tumors). It works by changing the action of your immune system, directing it to attack cancer/tumor cells.


The most common side effects reported in the study include fatigue/asthenia, nausea, diarrhea, anemia, and constipation. Additional common side effects reported include vomiting, joint pain, itching, rash, fever, and hypothyroidism (low levels of thyroid hormones).


We hope that this wonder drug can be mass-produced and its cost subsidized, especially as it costs $11,000 per dose so that more people wouldn't have to see cancer as a death sentence anymore.


Thanks for reading!

HOW LONG DOES TETRAHYDROCANNABINOL, THC LAST IN THE BODY?

HOW LONG DOES TETRAHYDROCANNABINOL, THC LAST IN THE BODY? Tetrahydrocannabinol is the principal psychoactive constituent of cannabis and one of at least 113 total cannabinoids identified on the plant.THC is the main psychoactive compound in marijuana. It's what makes people feel "high."  THC and its metabolites are stored in body fat before finally clearing out through the kidneys.  For someone who has used it daily for so long, your body will be completely saturated with the stuff for some time after quitting.  At 83 days, you're pretty much right on the edge of having it out of your system but just aren't quite there yet.  One-time use will usually stay in your system for 5-8 days. If you use cannabis 2-4 times per week and then stop, you'll test positive for 11-18 days. Long-time heavy users should expect positive results for at least 90 days after cessation and even up to 120 days for those who are larger or with a slow metabolism.  HOW TO REDUCE THC IN TH...
