Male seminal fluid proteins are known to affect female reproductive behavior and physiology by reducing mating receptivity and by increasing egg production rates. Such substances are also though to increase the competitive fertilization success of males, but the empirical foundation for this tenet is restricted. Here, we examined the effects of injections of size-fractioned protein extracts fro...

1. Kidney homogenates from rats injected with egg white and from control rats were fractionated simultaneously into six fractions and the content of acid phosphatase, ribonuclease, desoxyribonuclease, cathepsin, and beta-glucuronidase in corresponding fractions from treated and untreated animals was compared. These observations were correlated with the amount of dark brown bottom sediments in f...

The purpose of this study was to examine the effect of biopolymer encapsulation on the digestion of total lipids and cholesterol in egg yolk using an in vitro human digestion model. Egg yolks were encapsulated with 1% cellulose, pectin, or chitosan. The samples were then passed through an in vitro human digestion model that simulated the composition of mouth saliva, stomach acid, and the intest...

A. The catalytic activity of the tissues of newly born and adult rabbits. 1. There is practically no difference between the catalytic power of the blood, brain or muscle of newly born and adult rabbits. 2. The kidneys and lungs are less active in the newly born, but increase rapidly during the first days of life. 3. The liver is more active in the newly born than in the adult rabbit. B. The cat...

In present investigation, the effect of egg albumin on the rate of dissolution of analgesic tablets has been studied. Three sets of binder containing egg albumin in different ratios were used to prepare laboratory scale formulations and their dissolution behavior was studied. The best result was achieved from formulation having all the three binders (egg albumin, gelatin and corn starch) in 1:1...

The present investigation was carried out to study the effect of rebamipide in experimentally induced bronchial asthma in mice. Trypsin and egg-albumin induced chronic model of asthma was used and various parameters were measured on the 35th day. The asthmatic control group showed lower level of haemoglobin saturation with oxygen, tidal volume, airflow rate and higher respiratory rate, serum bi...

We conducted an ultrasonographic experiment on a pregnant manta ray, Manta alfredi (Chondrichthyes, Batoidea). This study showed how the embryo of the live-bearing elasmobranchs respires in the body of the female. In the embryonic stage, the manta ray embryo takes in uterine fluid by buccal-pumping. After birth, the manta ray shifts its respiratory mode from buccal-pumping to ram-ventilation. T...
