The three major types of inherited genetic resistance (sickle-cell disease, thalassaemias, and glucose-6-phosphate dehydrogenase deficiency) were present in the Mediterranean world by the time of the Roman Empire, about 2000 years ago. [19] Molecular methods have confirmed the high prevalence of P. falciparum malaria in ancient Egypt. [20]
In 1968, Robert Edwards and Richard Gardner reported the successful identification of the sex of rabbit blastocysts. [8] It was not until the 1980s that human IVF was fully developed, which coincided with the breakthrough of the highly sensitive polymerase chain reaction (PCR) technology.

Lovotibeglogene autotemcel, sold under the brand name Lyfgenia, is a lentiviral gene therapy used for the treatment of sickle cell disease. [1] [3] [4] [5]The most common side effects include stomatitis (mouth sores of the lips, mouth, and throat), low levels of platelets, white blood cells, and red blood cells, and febrile neutropenia (fever and low white blood cell count), consistent with ...
One of 12 roundels depicting the "Labours of the Months" (1450-1475) A sickle, bagging hook, reaping-hook or grasshook is a single-handed agricultural tool designed with variously curved blades and typically used for harvesting or reaping grain crops, or cutting succulent forage chiefly for feeding livestock.
He found that the prevalence of sickle-cell trait (heterozygous condition) among people inhabiting coastal areas was higher than 20%. [8] At the time the highest record was 8% among African-Americans.) [ 10 ] He was posed with the question as to why such a deadly disease (in homozygous condition ) would be more prevalent in a localised area in ...
A sickle allele is always the same mutation of the beta-globin gene (glutamic acid to valine at amino acid six). In contrast, beta-thalassemia alleles can be created by many different mutations including both deletion and non-deletion forms.
The treatment was approved in the United Kingdom for the treatment of sickle cell disease and transfusion-dependent beta thalassemia in November 2023. [9] [10] [11] It was approved in the United States for the treatment of sickle cell disease in December 2023 and for the treatment of transfusion-dependent beta thalassemia in January 2024. [8 ...
