While the goal of African pastoralists is health and longevity of herd and household, some of their management strategies appear to counter this long-term goal. Pastoralists in the far north region of Cameroon, for example, do not always remove chronically sick animals from their herds, even though chronic diseases, such as brucellosis, are contagious and have the potential to cause fertility p...

BACKGROUND The late descent of a testicle into the scrotum may impair its development. Reduced fertility is the main risk of primary cryptorchidism even after timely treatment, as histopathological changes (Leydig cell hypoplasia) already become apparent in the first few months of life. There is evidence, however, that treatment is often delayed. Hormonal and surgical treatments complement each...

In the present study, efficiency of intra-abdominal use macerated oil obtained from Taşköprü Garlic (Kastamonu/Türkiye), which is one products with geographical indication-from European Union, in preventing postoperative adhesions. The chemical structure macerated-oil, prepared using fresh-garlic at a concentration 1.2 g/ml olive oil, was analyzed by spectrophotometric and chromatographic metho...

Long-term yield performance and yield stability of common cropping systems needs to be simultaneously assessed at various fertility regimes. Based on a consecutive 19-year field trial, including eight fertilization treatments with different combinations of nitrogen (N), phosphorus (P), potassium (K) and recycled manure (RM), the effects of fertilization and crop rotation on corn (Zea mays L.) y...

This study is was designed to assess the ecological risk associated with chemical pollution caused by heavy metals and PAHs on the basis of their ecotoxicological properties in sediments collected from the Rzeszów dam reservoir (Poland). The sediment samples were collected from three sampling stations: S1-inlet, backwater station, S2-middle of reservoir, S3 outlet, near the dam. The sediments' ...

Two diterpenoid surfactants with ammonium head groups and bromide (S1) or tosylate (S2) counterions have been synthesized. Exploration of these biomimetic species made it possible to demonstrate that even minor structural changes beyond their chemical nature may dramatically affect their solution behavior. While their aggregation thresholds differ inconsiderably, morphological behavior and affi...

A field experiment was conducted to evaluate the residual effect of rock phosphate and waste mica enriched compost on phosphorus and potassium supplying capacity under soybean crop grown after wheat in a Typic Haplustept. Enriched compost prepared using rice straw, rock phosphate, waste mica and Aspergillus awamori had higher chemical (total P, K, Ca, Mg and micronutrients) as well as biologica...
