Study of In Vivo Plaque Formation

Journal of Dental Research, 1976
A technique was developed by which plaque accumulations on intraoral artificial surfaces could be viewed with a scanning electron microscope (SEM). Micrographs of two plaque specimens from a given individual appeared similar; however, plaque specimens from different individuals encompassed a wide range of variation in terms of content and thickness.

Ciprofloxacin: in vivo genotoxicity studies

Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2001
The fluoroquinolone ciprofloxacin is widely used in antimicrobial therapy. It inhibits the bacterial gyrase and in high concentrations in vitro also the functionally related eukaryotic topoisomerase-II, which resulted in genotoxic effects in several in vitro tests.

A study of chlorophyll bin vivo

Biochimica et Biophysica Acta (BBA) - Bioenergetics, 1970
Abstract 1. The absorption spectrum of chlorophyll b in vivo at 77°K is presented as the difference spectrum between preparations of spinach and chlorophyll b -free Vischeria stellata chloroplasts. 2. A shoulder on this spectrum around 662 nm is due to a component different from chlorophyll b .

In Vivo Studies of Mitochondrial Respiration

1978
In the course of an investigation of adding new collateral blood flow to the cortex of ischemic patients, the point was raised as to whether an increase in cortical oxygen tension would lead to improved oxygen utilization and energy production. If so, this might at least partially supply an explanation for improved neurologic function.

In vivo studies with fibre components

Scandinavian Journal of Gastroenterology, 1987
There are few studies in man examining the in vivo effects of dietary fibre on bile acid metabolism but divergent results have been recorded depending on the amount and type of fibre eaten. Studies in which the fibre components pectin, cellulose, and lignin were fed to normal volunteers for four weeks have been reported.

Study of In Vivo Radiographic Densitometry

Journal of Dental Research, 1970
An intensive study of radiographic densitometry was made to determine its reliability as a biologic measuring method. Such measurements are useful but have limitations.

In Vivo Patch-Clamp Studies

2020
Intact and functioning brain enables quantification of neural activities directly associated with real world such as visual and auditory information. In vivo patch clamp can record different types of neuronal activity, such as spiking responses, membrane potential dynamics, and synaptic currents (e.g., EPSC, IPSC) in either anesthetized or awake or ...

In vivo models in the study of osteopenias.

European journal of clinical chemistry and clinical biochemistry : journal of the Forum of European Clinical Chemistry Societies, 1991
A better insight into bone pathophysiology is required for a full understanding of the mechanisms leading to bone loss in humans. Animal models of bone disease appear to be the most valuable for this purpose. Certain differences in bone metabolism exist between various species.

In vivo studies with antisense oligonucleotides

Trends in Pharmacological Sciences, 1997
The ability of short, synthetic, single- stranded DNA or RNA oligonu- cleotides to interdict individual gene expression in a sequence-specific manner is the basis for antisense oligonucleotide-based therapies (for recent reviews see Refs 1,2). Unlike traditional drugs which typically interact with proteins, these oligonu- cleotide molecules are ...
