Laboratory Testing

A partially distended gallbladder means that the gallbladder is not completely full or swollen but is moderately inflated with bile or other fluids. This condition can be seen on imaging studies like ultrasound and may indicate an underlying gallbladder issue, such as inflammation or blockage of the bile ducts. Medical evaluation is usually needed to determine the cause and appropriate treatment.

Elevated AST (aspartate aminotransferase) and ALT (alanine aminotransferase) levels typically indicate liver damage or inflammation. Levels of 105 and 106 are moderately elevated and should be further evaluated by a healthcare provider to determine the underlying cause, such as liver disease, medication side effects, or alcohol consumption. Treatment will depend on the specific diagnosis.

If an Rh negative person is exposed to Rh positive blood, their immune system may produce antibodies against the Rh antigen. Upon subsequent exposure to Rh positive blood, these antibodies can attack and destroy the Rh positive red blood cells, leading to a condition called hemolytic disease of the newborn (HDN) in pregnant women or a transfusion reaction in non-pregnant individuals.

The meat of a slaughtered animal is typically obtained from butchers or slaughterhouses that follow specific guidelines and regulations for humane slaughter. The meat of a dead animal, on the other hand, may not have undergone proper slaughtering procedures and could pose health risks due to potential contamination or disease. It is important to purchase meat from reputable sources that follow ethical and sanitary practices.

The world record for the longest period a person has stayed awake is 11 days and 25 minutes, held by Randy Gardner in 1964. However, it is not recommended to stay awake for such extended periods as it can have severe health consequences.

No, insects do not have lungs, they have a system of small holes in their exoskeleton which allows air entry into a system of narrow tubes from which it can diffuse directly into their living tissues.

Neurotoxins are substances that can damage, disrupt, or destroy nerve tissue and function in the body. They can interfere with neurotransmitter production, alter ion channels, or cause other harmful effects on the nervous system, leading to symptoms ranging from mild discomfort to severe paralysis or death. Examples of neurotoxins include lead, mercury, botulinum toxin, and certain pesticides.

Yes - but both of the parents would have needed at least one O allele and one Rh negative allele.

If either parent was homozygous AA or OO (or homozygous Rh positive), then this would not be possible.

The alien autopsy video, released in 1995, was proven to be a hoax. The supposed alien dissected in the video was revealed to be a prop created by special effects artists. There is no scientific evidence to support the existence of alien autopsies.

The sensitivity numbers on a urine culture and sensitivity test indicate the effectiveness of different antibiotics in treating a specific bacteria found in the urine sample. It helps determine which antibiotic will be most effective in treating the infection. The higher the sensitivity number, the more effective the antibiotic is against that particular bacteria.

A fetus is generally not visible on ultrasound until about 5-6 weeks of pregnancy. At 3 weeks, the embryo is very small and not typically detectable on ultrasound.

Yes, it is possible for a B negative child to be born to parents who are type A positive and O positive. This is due to the inheritance of blood type alleles from both parents that can result in the child having a different blood type than either parent.

The absolute eosinophil count measures the white blood cell count. When a person is infected with a bacterial strain, flu or disease the white cell count can increase or decrease. The test determines if the eosinophil are active or dormant.

The normal range for activated partial thromboplastin time (APTT) is typically between 25-35 seconds. However, it can vary slightly depending on the laboratory's specific reference range. Outside of this range may indicate a bleeding disorder or a clotting factor deficiency.

There are 8 cranial bones in the human skull. They include the frontal bone, parietal bones, temporal bones, occipital bone, sphenoid bone, and ethmoid bone.

A pelvocalyceal system refers to the structure within the kidney that includes the renal pelvis and calyces. The renal pelvis is a funnel-shaped structure that collects urine from the kidney and connects to the ureter, while the calyces are cup-like structures that collect urine from the kidney tubules.

A high number of pus cells in clumps in a urinalysis may indicate a urinary tract infection. This could be caused by bacteria or a fungal infection in the urinary tract. Further testing and evaluation by a healthcare provider may be needed to determine the specific cause and appropriate treatment.

The longest recorded time someone has stayed awake without the use of stimulants is about 11 days, when a California high school student set a world record in 1964. However, prolonged sleep deprivation can have serious health consequences and is not recommended.

A human brain is larger overall, sheep brains have larger olfactory bulbs though, they also have an area on the sides, around where the temporal lobe is where their eyes go, this causes an indentation humans don't have.

A high level of AST (aspartate aminotransferase) in the blood typically indicates liver damage or injury. AST is an enzyme found in high levels in the liver, heart, muscles, and other organs, so elevated levels of AST can suggest liver disease, such as hepatitis, cirrhosis, or liver cancer.

To correct eyesight, you can typically use eyeglasses, contact lenses, or corrective surgery like LASIK. It's important to visit an eye care professional to determine the best option for your particular vision needs. They will provide a thorough eye examination and prescribe the most suitable solution for you.

To store a DPPH in methanol solution for long-term purposes, it is recommended to seal the container tightly to prevent evaporation or contamination. Store the solution in a dark, cool place to minimize degradation of the DPPH. Periodically check the solution for any color changes or signs of degradation.

The negative in "O Negative" means that it's Rh negative, meaning that anyone, either positive or negative can receive that Rh type. O negative blood can be given to anyone. It's the Universal Donor.

Two individuals worked on opposite sides of the Atlantic Ocean to isolate streptococcus pneumoniae and grow it in a culture. Louis Pasteur of France was the first to publish his report, in January 1881, after finding the bacteria in the saliva of a youngster with rabies. George Miller Sternberg of the United States sampled his own saliva and successfully grew the bacteria as a culture in September 1880, but did not publish his report until April 1881.

In 1911, scientists attempted to find an effective vaccine against the pneumonia caused by streptococcus pneumoniae. When penicillin came into popular use in the 1940s, patients were inoculated with that in the belief that the penicillin would kill the infection. Many patients died. By the 1960s, a true pneumonia vaccine was again sought. The first pneumococcal vaccine was produced and licensed in November 1977. This vaccine was composed of the 14 serotypes known to cause about 80 percent of all bacteria-caused pneumococcal cases in the United States. Two vaccines which covered 23 serotypes were produced and licensed in July 1983.

The First Isolation of Streptococci

In 1880 French biologist Louis Pasteur, credited with spreading the idea that microbes cause disease, isolated the bacteria that caused pneumonia. He named it "microbe septicemique du salive." That same year in the United States, George Miller Sternberg isolated the same bacteria, naming it Micrococcus pasteuri. Although both were strains of streptococci, it was not until 1974 that the name of the bacteria that Pasteur and Sternberg isolated was changed to Streptococcus pneumoniae.

The Naming of Streptocci

While Pasteur and Sternberg were the first to isolate a strain from this group of bacteria, the name comes from Alexander Ogston, a Scottish doctor who detected a group of spherical bacteria arranged in chains. Because of their appearance, he named them Streptococci, from the Greek word "streptos," meaning "twisted."

You find out if something is safe or not and you find out the effectiveness of something. But animal experimentation is not fool proof and sometimes all the hard work of testing is usless. I think that we should stop animal experimentation and stick with good old natural things instead of trying to find out if chemicals are safe.
