c.451dupT in KLKB1 is common in Nigerians, confirming a higher prevalence of severe prekallikrein deficiency in Africans compared to Europeans

2020

Essentials Prekallikrein (PK) deficiency is a recessive trait with isolated aPTT prolongation. KLKB1 c.451dupT is common in Nigerians (7/600 alleles) and absent in a European group (0/600). To date, all genotyped PK-deficient patients of African ancestry were homozygous for 451dupT. Diagnostics of isolated aPTT prolongation in African descendants should include PK testing. ABSTRACT: Background Severe prekallikrein deficiency (PK deficiency) is an autosomal-recessive condition thought to be very rare. Recently we reported that the previously unnoticed variant c.451dupT, p.Ser151Phefs*34 in KLKB1, which is listed in databases aggregating genome data, causes PK deficiency and is common in Afri…

Towards science education for sustainable development in developing countries : a study of Ethiopia, Ghana and Nigeria

2006

Kestävän kehityksen edistäminen on yhteinen tavoite maailmanlaajuisesti. Siihen liittyvä tutkimus kasvatuksen ja opettajankoulutuksen näkökulmista on melko harvinaista. Tämän tutkimuksen tarkoituksena oli arvioida kestävän kehityksen ilmenemistä afrikkalaisessa luonnontieteiden opetuskontekstissa hyödyntämällä TIMSS 1999 -tutkimuksen luonnontieteiden osuuden arviointivälineitä. Yhtäältä arvioitiin etiopialaisten, ghanalaisten ja nigerialaisten opiskelijoiden suorituksia luonnontieteiden testissä, joka oli laadittu ja muokattu näiden maiden luonnontieteiden opetussuunnitelmien pohjalta. Toisaalta kartoitettiin opettajien mielipiteitä luonnontieteiden ja kestävän kehityksen opetuksesta muutam…

Influence of harvesting time on composition of the essential oil of Thymus capitatus (L.) Hoffmanns. & Link. growing wild in northern Sicily and its …

2019

One of the main factors affecting historical art crafts material is the biodeterioration performed by bacteria and fungi, in archives, museums or private collections. Several microorganisms cause degradation to the natural organic material such as fibers, woods, and dyes as well as to stone objects. These alterations produce deterioration of physical, chemical, mechanical and esthetic properties. Consequently, in this publication, we report the high antibacterial and antifungal activities of wild thyme essential oil, oil that can be used as an alternative natural tool in the fight against microorganisms affecting historical art crafts.Essential oil of the Thymus capitatus growing wild in no…
