PURPOSE:

To investigate the involvement of the chemokines CXCL10/IP-10, CXCL11/I-TAC, CXCL8/1L-8, CXCL6/GCP-2, CCL3/MIP-1alpha, and CCL18/PARC, and gelatinases A and B in uveitis.

DESIGN:

Prospective, experimental, case-control study.

METHODS:

Aqueous humor samples from 30 patients with active uveitis, and 14 control patients and paired serum samples were assayed for chemokines with specific enzyme-linked immunosorbent assays (ELISAs) and for gelatinase levels by quantitative zymography.

RESULTS:

Agricultural contamination with pesticides and antibiotics is a challenging problem that needs to be fully addressed. Bee products, such as honey, are widely consumed as food and medicine and their contamination may carry serious health hazards. Honey and other bee products are polluted by pesticides, heavy metals, bacteria and radioactive materials. Pesticide residues cause genetic mutations and cellular degradation and presence of antibiotics might increase resistant human or animal’s pathogens. Many cases of infant botulisms have been attributed to contaminated honey.

The orientation of combs in traditional beehives is extremely important for obtaining a marketable honey product. However, the factors that could determine comb orientation in traditional hives and the possibilities of inducing honey bees, Apis mellifera (L.), to construct more desirable combs have not been investigated. The goal of this experiment was to determine whether guide marks in traditional hives can induce bees to build combs of a desired orientation. Thirty-two
