Carbonic anhydrase is an enzyme that plays important roles in the conversion of carbon dioxide to bicarbonate, acid-base balance, and in subembryonic fluid formation in the early Japanese quail embryo. While turkey egg storage longer than 10 d is known to increase the rate of embryo mortality, little is known of the biological mechanisms that contribute to this phenomenon. In this study, we exa...

trissolcus grandis (thomson) (hymenoptera: scelionidae) is the most important egg parasitoid of the common sunn pest, eurygaster integriceps puton (hemiptera: scutelleridae) in iran. demographic characteristics may be used for preliminary screening of parasitoid species or populations as well as for predicting their efficiency under different physical conditions in the field. in this study, the...

Rabbit antibody directed against normal allantoic fluid reduced the protective power of influenza vaccine prepared from egg-grown PR8 virus. A similar vaccine prepared from mouse lung virus was not inhibited. Preimmunization of mice with normal allantoic fluid or with egg-grown influenza B/Lee vaccine (crude or purified) inhibited the protective power of PR8 egg vaccine but did not affect a sim...

Background: Ovarian hyperstimulation syndrome is one of the most common complications of infertility treatment. As the fluid-filled egg follicles begin to grow within the ovary, the ovary enlarges. Sometimes, that fluid can cause fluid elsewhere in the body to shift into the abdominal cavity or the lungs. Women with PCOS are at a greater risk for developing OHSS due to the already large number ...

The major yolk protein (MYP) is localized to the egg and coelomic fluid of the adult sea urchin. While the egg-localized MYP has been extensively studied, much less is known about the coelomic fluid-localized protein. Therefore, we have conducted a comparative biochemical analysis of these proteins. Sucrose density gradient ultracentrifugation revealed unique elution profiles for the MYP specie...

1. Experiments designed to study, in the rabbit, the passage of foreign proteins from the blood stream into synovial fluid and to compare such passage with that taking place into the aqueous humor, spinal fluid, and urine are described. 2. Crystalline egg albumin and horse serum proteins regularly appeared in the knee joints within short periods of time following their intravenous injection. 3....

The present investigation was carried out to study the effect of PHE in experimental induced bronchial asthma in mice. Trypsin and egg-albumin induced chronic model of asthma was used and various parameters were measured on 35 day. The asthmatic control group showed lower level of pO2, tidal volume, airflow rate and higher respiratory rate, serum bicarbonate level, eosinophil count in bronchoal...

Mating stimulates the rate of egg-laying by female insects. In Drosophila melanogaster this stimulation is initially caused by seminal fluid molecules transferred from the male (Acps or accessory gland proteins; reviewed in [1] [2] [3]). Egg-laying is a multi-step process. It begins with oocyte release by the ovaries, followed by egg movement down the oviducts and the deposition of eggs onto th...

In internally fertilizing animals, seminal fluid is usually added to the spermatozoa, together forming the semen or ejaculate. Besides nourishing and activating sperm, the components in the seminal fluid can also influence female physiology to augment fertilization success of the sperm donor. While many studies have reported such effects in species with separate sexes, few studies have addresse...
