Hemoglobin is a protein containing iron that facilitates the transportation of oxygen in red blood cells. [16] Hemoglobin in the blood carries oxygen from the lungs to the other tissues of the body, where it releases the oxygen to enable metabolism. A healthy level of hemoglobin for men is between 13.2 and 16.6 grams per deciliter, and in women ...

Chromosome 15 is one of the 23 pairs of chromosomes in humans.People normally have two copies of this chromosome. Chromosome 15 spans about 99.7 million base pairs (the building material of DNA) and represents between 3% and 3.5% of the total DNA in cells.
RDW-SD is calculated as the width (in fL) of the RBC size distribution histogram at the 20% height level. This parameter is, therefore, not influenced by the average RBC size (mean corpuscular volume, MCV). [7] RDW-CV (expressed in %) is calculated with the following formula: RDW-CV = (1 standard deviation of RBC volume ÷ MCV) × 100%. [8]
Lead shot is still the best ballistic performer, but environmental restrictions on the use of lead, especially with waterfowl, require steel, bismuth, or tungsten composites. Steel, being significantly less dense than lead, requires larger shot sizes, but is a good choice when lead is not legal and cost is a consideration.
Elevated blood lead levels (BLLs) in adults can damage the nervous, hematologic, reproductive, renal, cardiovascular, and gastrointestinal systems.. Current research continues to find harmful effects in adults at BLLs previously considered harmless, such as decreased renal function associated with BLLs at 5 micrograms per deciliter (μg/dL) and lower, and increased risk of hypertension and ...
Fragment of a hypodermic needle stuck inside the arm of an IV drug user (x-ray). Drug injection is a method of introducing a drug into the bloodstream via a hollow hypodermic needle, which is pierced through the skin into the body (usually intravenously, but also at an intramuscular or subcutaneous, location).
Lead shot-related waterfowl poisonings were first documented in the US in the 1880s. [57] By 1919, the spent lead pellets from waterfowl hunting was positively identified as the source of waterfowl deaths. [312] Lead shot has been banned for hunting waterfowl in several countries, [57] including the US in 1991 and Canada in 1997. [313]
