The Effects of Relaxin on The Composition of Bovine Milk
<p>Protoplasm is a fragile substance keeping its homeostatic properties by many physiochemical phenomena. Much is known about the properties of protoplasm; but it is, perhaps, only meager when compared to what is yet to be learned. Such physical changes as electrical impulses, diffusion, and …

The effect of sugars on amino-acid transport
… oatabolised without becoming part of the "living protoplasm". This concept implied that "circulating protein" was in solution, that protein catabolim could take place only in that state, and that when living protoplasm "died", it was first dissolved, and subsequently became part of the circulating …

A Comparative Study of Degenerative Tissue
… In growth more material is used by the body-protoplasm that is expelled. Nutrition includes excretion i.e. the removal of spent material which is usually poisonous and which if allowed to remain in the body organism would impair nutrition in its fullest sense. The objects of nutrition are …

Pollen digestion in flower-feeding Scarabaeidae : protea beetles (Cetoniini) and monkey beetles (Hopliini)
… in order to benefit from the pollen's nutritious protoplasm. There are a variety of mechanisms that pollen-feeders may use to deal with the exine. Collembolans secrete exinase that breaks down the wall, but other pollen-feeders do not produce this enzyme. Pollen-feeders that are unable to ingest …

The killing of plant tissue by low temperature
… results from the withdrawal of water from the protoplasm. The amount of water loss necessary to result in death varies with the different plants and different tissues. This paper studies the effects of cold weather on plant tissue, specifically concerning tissue death and the preventative …

Spontaneous generation in the 1870s: Victorian scientific naturalism and its relationship to medicine.
… posed to naturalism in terms of evolution, protoplasm and naturalistic explanations of disease. The effects of Tyndall's campaign for the germ theory on the medical profession are described. In order to understand how scientific knowledge was introduced into medicine, Chapter 6 examines the …

The oxygen uptake by pseudomonas fluorescens on glucose, xylose, arabinose and acetate under varying conditions of substrate concentration and environmental temperature
… Pseudomonas fluorescens (stated as dry bacterial protoplasm) were suspended in 2.5 milliliters of 0.05 molar phosphate buffer of pH 6.8. At 25 °C, for all substrates with the exception of acetate, the rate of oxygen uptake is dependent on concentration in the lower concentration ranges, and …

Effects of sublethal and lethal temperatures on plant cells
… chloroplasts being apparent in some cells. The protoplasm in all the cells show characteristics of coagulation and the plasma membrane and the nuclear membrane appeared to be broken-up. A sublethal temperature treatment, which had produced chlorosis in vivo, reduced the Hill reaction of isolated …

GENOMIC TOOLS TO IMPROVE PEACH (P. PERSICA L. BATSCH) RESILIENCE TO CLIMATE CHALLENGES
… dehydration resulting in the coagulation of the protoplasm. Flower buds are hardiest during the winter, when they are fully dormant. During dormancy the lack of active xylem connection may protect flower organs thus ice formation is only possible within the bud scales. Upon dormancy breaking …
