Surveillance of Pregnancy Loss in Human Populations

American Journal of Industrial Medicine, 1983
Surveillance of pregnancy loss as a way to detect hazardous exposures is attractive in principle. However, there are no established methods for monitoring pregnancy loss in humans. Surveillance is difficult because most loss occurs within the first 12 weeks of gestation, when pregnancy may not he documented or even recognized. Three possible approaches

Channel Loss in Contactless Human Body Communication

2018 40th Annual International Conference of the IEEE Engineering in Medicine and Biology Society (EMBC), 2018
Human body communication (HBC) utilizes human body as the transmission medium to facilitate data communications in a wireless body area network (WBAN). It normally uses a pair of transmitting (Tx) and receiving (Rx) electrodes clinging to the body surface to form a low-loss body channel, so a higher energy efficiency can be achieved in comparison to ...

Loss of heterozygosity in human germinal tumors

Cytogenetic and Genome Research, 1989
The frequency of losses of heterozygosity has been investigated in 14 germinal tumors of the testis. Nonrandom deletion of whole or part of chromosome 11 was observed in four cases. In addition, loss of heterozygosity of all the informative loci analyzed was detected in one ovarian teratoma, indicating its post-meiotic origin.

Heat Losses From the Human Head

Journal of Applied Physiology, 1957
A simple gradient calorimeter was developed for measurements of nonevaporative heat loss of the head, and used on three subjects, with heads unprotected but the body adequately clothed, at temperat...

Loss of constitutional heterozygosity in human astrocytomas

Acta Neurochirurgica, 1992
Inactivation of tumour suppressor genes or anti-oncogenes as well as activation of dominant acting oncogenes seem to be important mechanisms in the pathogenesis of gliomas. We compared constitutional and tumoural genotypes at different restriction fragment length polymorphism loci (RFLP) on chromosomes 10 and 17 in 15 unrelated individuals.

Human Bite Losses of the Lower Lip

Plastic and Reconstructive Surgery, 1979
In two years, in our hospital in Nigeria, we saw 16 patients with lower lip losses caused by human bites. These are presented, together with the methods used for early management and subsequent repair.

Panting as a human heat loss thermoeffector

2018
The human autonomic nervous system participates in the control of thermoregulatory responses that are employed to regulate core temperature following deviations of skin temperature and/or core temperature from their respective resting values. This permits a regulation of the core temperature (TC) at 37.0 ± 1°C with superimposed circadian variations in ...
