Neonatal Mortality By Order Of Birth And Age Of Parents.
American journal of hygiene
A study of all infants born in New York State, exclusive of New York City, in 1936 has been made with the intent of investigating the effects of order of birth and age of paretns of neonatal mortality. The study revealed these results. 1) Of the 82,140 infan...

Birth Weight And Gestation Time In Relation To Maternal Age, Parity And Infant Survival.
Annals of eugenics
This study examined birthweight and gestation time in relationship to maternal age, parity, and infant survival in 13,730 (7037 male, 6693 female) births at an obstetric hospital in 1935-46. Preliminary analysis of the data indicated that nonsurvivors were si...

Survey Of A Scottish Diabetic Clinic: A Study Of The Etiology Of Diabetes Mellitus.
The Journal of clinical endocrinology
Certain features of a group of 1309 diabetics were studied. The group was considered representative of Scottish diabetics since the sex distribution of cases corresponded to the sex distribution of deaths from diabetes recorded in the official mortality stati...

Resistance-Suppressing Activity Of Transformed Syrian Hamster Cells And Their Ability To Metastasize
Biulleten' eksperimental'no? biologii i meditsiny
Hamster embryo cells spontaneously transformed in vitro (HETr) with low metastatic activity were not capable to depress natural antitumor resistance in vivo in contrast to some other lines of Syrian hamster tumor cells. The resistance, depressing and metastati...

Chromosome Aberrations And Molecular Weight Of Single-Stranded Dna Fragments In Embryonal Fibroblasts Of Mouse Strains 101/H And Cba
Biulleten' eksperimental'no? biologii i meditsiny
Fibroblasts from 101/H mouse fetuses manifest a higher rate of spontaneous chromosome aberrations as compared to fibroblasts from CBA fetuses. The molecular weight of single-strand DNA fragments from 101/H mice was found to be lower than that in CBA mice. No d...
