in this experiment, the effects of fennel and thyme extracts with and without flaxseed were investigated on performance and egg quality of leghorn-type laying hens (hy-line w-36). 200 laying hens from 26 to 38 weeks of age were assigned to five dietary treatments with five replications. the treatment groups were: 1) control (a diet without any additives); 2) control diet plus fennel (40 mg/kg f...

Bed bugs are ectoparasites of humans and require a blood meal for their growth and reproduction. Since humans consume Ibuprofen as pain medication and drink coffee (caffeine), bed bugs are likely to acquire these drugs through blood feeding. In this study, we determined the biological effects of Ibuprofen and caffeine on bed bug feeding, fecundity and egg hatch. Five concentrations of Ibuprofen...

BACKGROUND The convergent distribution of the Human Immunodeficiency Virus (HIV) and helminth infections has led to the suggestion that infection with helminths exacerbates the HIV epidemic in developing countries. In South Africa, it is estimated that 57% of the population lives in poverty and carries the highest burden of both HIV and helmith infections, however, the disease interactions are ...

BACKGROUND Gal d 1 (ovomucoid) is the dominant allergen in the chicken egg white. Hypoallergenic variants of this allergen can be used in immunotherapy as an egg allergy treatment approach. We hypothesised that disruption of two of the nine cysteine-cysteine bridges by site-directed mutagenesis will allow the production of a hypoallergenic variant of the protein; Methods: Two cysteine residues ...

objective: furcal perforation is an undesirable complication that may occur during root canal therapy and seriously compromises the prognosis of endodontic treatment. the prognosis of furcal perforation repair depends on the prevention of bacterial infection of the perforation site. thus, use of a biocompatible material for complete sealing of the perforation site is critically important. this ...

BACKGROUND Egg laying in Caenorhabditis elegans has been well studied at the genetic and behavioral levels. However, the neural basis of egg-laying behavior is still not well understood; in particular, the roles of specific neurons and the functional nature of the synaptic connections in the egg-laying circuit remain uncharacterized. RESULTS We have used in vivo neuroimaging and laser surgery...

Studies were made on the number of egg clutch, copulating pairs, duration of mating, duration of egg laying, and weight of egg clutch of Pila globosa by inducing it with Pituitary Gland (PG) and Optic Tentacle cut (OT) under laboratory condition. The effect of inducing the animal with PG and OT cut showed that it resulted in an increase in the number of egg clutch in comparison with that of the...

In this study, the effects of boric acid and humate supplementation into hen diets on egg production and quality parameters and blood cholesterol levels were examined. For this aim, totally 160, 40 weeks of age, Hyline-White 98 layers were randomly divided into control and 3 treatment groups each containing 40 birds and 10 replicates (each with 4 birds). There was no boric acid or humate supple...
