A recent paper Chase, Rauch, and Smith (i95I) describe the normal IN development of the hair in the mouse. Using the terms originally suggested by Dry (1926), the developmental cycle is divided into three phases. The anagen or active phase is characterized by the proliferation of the hair germ, the formation of the bulb, and the production of the hair. Since this is the phase of the most abundant changes in the follicle, it is further divided into six sublstages, anagens I-VI (Chase et al… Expand
‘Matted’, a New Hair-mutant in the House-mouse: Genetics and Morphology
TLDR
The present paper deals with the genetics of the new mutant and explains its effect in terms of the underlying abnormalities of hair structure, which are associated particularly with the later stages of each coat generation. Expand
Intestinal Dysbiosis and Biotin Deprivation Induce Alopecia through Overgrowth of Lactobacillus murinus in Mice.
TLDR
It is found that antibiotic-induced dysbiosis, in particular, overgrowth of Lactobacillus murinus, impaired gut metabolic function and led to the development of alopecia in mice fed a biotin-deficient diet. Expand
Effect of Primary Biotin Deficiency on the Skin of Germ-Free and Conventional Mice Fed a Purified Biotin-Deficient Diet without Supplementation with Egg White.
TLDR
The histological changes in the alopecic skin were degeneration of the medulla of hair and the cortex of hair in germ-free mice fed the deficient diet and downgrowth of the hair root. Expand
Genome-wide association study identifies variants associated with hair length in Brangus cattle.
TLDR
Genetic variants associated with the length of the undercoat and topcoat of cattle utilizing 1456 Brangus heifers genotyped with the Bovine GGP F250 array may contribute to a shorter hair coat and more thermotolerant animals. Expand

Critical Stages of Hair Development and Pigmentation in the Mouse
TLDR
Stages in the normal hairdevelopment cycle are under consideration and greater detail in these stages is of value, and Dry's anagen stage has been divided into six rather precise and recognizable stages. Expand

TLDR
The growth potentials of the skin and its appendages are not appreciably affected by biotin deficiency, but normal differentiation and function are impaired, and there is an increase in the number of mesenchymatous cells, mast cells and leukocytic cells in the dermis of biotin deficient mice.

TLDR
The deleterious effects of unheated or uncoagulated egg white were gradually realized after numerous investigators had reported poor growth, loss of weight, hypochlorhydria, vomiting, diarrhea, "poor utilization," dermatitis, conjunctivitis, abscesses, diminished hemoglobin, spasticity, failure of lactation, nephritis and death in experimental animals from its use as the entire ration or as the source of protein in various diets.

Use of Sulfaguanidine in Nutrition Experiments.∗
TLDR
It has been shown that on a purified basal ration 0.5% sulfaguanidine greatly reduces the growth rate of young rats and the bearing of these results upon the possible synthesis of unidentified rat growth factors by intestinal bacteria is discussed. Expand
