which is caused by a mutant allele (Hb-) which in the homozygous condition in the past was often fatal to people at quite young ages. The mutation causes the formation of abnormal‚ sickle-shaped red blood cells that clog vessels‚ cause organ damage‚ and are inefficient transporters of oxygen. Individuals who are heterozygous (Hb-Hb+) have the sickle-cell trait (a mild form of the disease)‚ which is not fatal. Scientists were surprised to find a high frequency of the Hb- allele in populations in Africa

good Muslim. The five pillars are that there is no god but God‚ to offer prayer‚ to give charity‚ perform the hajj and to fast during Ramadan (HB 1: 7). The Muslims that follow the five pillars and follow Muhammad’s teachings will reach paradise. The first pillar is to accept that God is the only god and that he is the only one worthy of being worshiped (HB 1: 7‚ 25‚ 50‚ 63‚ 2: 594‚ Q 2: 176). This first pillar is very important in Islam because Islam is based around the idea of submitting to God

Oxygen binding Today scientists try to explore the chemistry basis behind the biological processes. As a result of this‚ new areas have evolved such as bioinorganic chemistry and bioorganic chemistry. In this section we will talk about an important concept in bioinorganic chemistry called “Metallobiomolecules”. Metallobiomolecules

Urinary incontinence will have a huge impact on your daily activities‚ so you do not want to hesitate to speak with your doctor about it. What is urinary incontinence? Essentially‚ it is the embarrassing problem of a loss of bladder control. The problem range from a small leak when you cough or sneeze to having a sudden urge that hits you so strongly that you do not have a chance of making it to the toilet. Before you can address the problem‚ you first have to understand that you have two types of

CO level in blood is represented as the percentage of Hb in the form of carboxyhemoglobin (COHb) which is a Hb-CO complex. Human body have 0.1-1.0% (Mercury‚ 1990)‚ 0.4-0.7% (Widdop‚ 2002) endogenous COHb saturation produced through the process of natural degradation of Hb. The rate of
