The issue of nitrate contamination has become increasingly acute, with the awareness their toxicity on human body and identification increasing sources contamination. Human intervention in natural nitrogen cycle serious repercussions that are manifested by its accumulation at one or more levels. use fertilizers agriculture is crucial to ensure food security, but unreasonable causes accumulation...

Rotavirus infections are the most common causes of infectious diarrhea in young children worldwide. We performed a genotyping rotavirus strains by RT-PCR for G (VP7) and P (VP4), Anadara tuberculosa, Lactuca sativa feces samples with collected Panama. Combinations genotypes (VP4) were identified tuberculosa: 30 (15%) corresponding to G12P[8], 26 (13%) G12P[6], 28 (14%) G1P[8], 7 (3.5%) G2P [6]....

Bu araştırmada ısıtmasız serada sonbahar döneminde bazı kıvırcık ve Yedikule tipi marul çeşitlerinde, dikimden itibaren belirli aralıklarla yapılan ölçüm analiz sonuçlarına göre vejetatif büyüme ile sırasında gerçekleşen değişimlerin incelenmesi amaçlanmıştır. Çalışmada 4 adet olmak üzere toplam sekiz çeşidi kullanılmıştır. Dikimden 10’ar gün kantitatif analizlerinde bitki boyu, kök boğazı çapı...

In previous studies we proposed the plant leaf fatty acid composition, and more precisely the ratio C18:3/(C18:0 + C18:1 + C18:2) as a tool to diagnose soil contamination ex situ. These studies led us to normalize this parameter as a biomarker of soil quality using Lactuca sativa growing under controlled conditions as the plant model species. The evaluation of the toxic effects of pollutants is...
