In vivo manipulation of interleukin-2 expression by a retroviral tetracycline (tet)-regulated system [PDF]

open access: yes, 2006
We have used the tetracycline (tet)-regulated system as described previously to evaluate the applicability of controlled gene expression in cancer gene therapy. As a model gene, we used the human interleukin-2 (IL-2) gene, which has been placed under the

Mechanism of Tetracycline Phototoxicity

open access: yesJournal of Investigative Dermatology, 1984
Studies were made to determine factors important in the phototoxicity mechanism of 7 clinically used tetracyclines (TC). The clinical phototoxicity, the rates of photochemical degradation, and the in vitro phototoxicity of the TCs were qualitatively but not quantitatively correlated.

Review of the anatomical basis for predicting plutonium alpha particle radiation induced osteogenic cancers

open access: yesThe Anatomical Record, EarlyView.
Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Genomic Insights Into a Strong Biofilm‐Forming Enterococcus faecalis MTR_EFS01 Strain Isolated From a Shrimp in Bangladesh

open access: yesAnimal Research and One Health, EarlyView.
This study characterizes a multidrug‐resistant and strong biofilm‐forming Enterococcus faecalis strain obtained from a shrimp sample in Bangladesh. ABSTRACT Enterococcus faecalis is known for its ability to form strong biofilms and its role as an opportunistic pathogen. In this study, we screened and characterized a multidrug‐resistant (MDR) and strong

The relationship between otolith increments and time for yellowfin and skipjack tuna marked with tetracycline [PDF]

open access: yes, 1980
ENGLISH: The rate at which increments are deposited on the sagittal otoliths of yellowfin (Thunnus albacares) and skipjack (Katsuwonus p elamis) tunas is determined by a markrecapture experiment using tetracycline. During growth in fork length from 40 to
