Total marrow irradiation reduces organ damage and enhances tissue repair with the potential to increase the targeted dose of bone marrow in both young and old mice.

Total body irradiation (TBI) is a commonly used conditioning regimen for hematopoietic stem cell transplant (HCT), but dose heterogeneity and long-term organ toxicity pose significant challenges. Total marrow irradiation (TMI), an evolving radiation conditioning regimen for HCT can overcome the limitations of TBI by delivering the prescribed dose targeted to the bone marrow (BM) while sparing organs at risk. Recently, our group demonstrated that TMI up to 20 Gy in relapsed/refractory AML patients was feasible and efficacious, significantly improving 2-year overall survival compared to the standard treatment.

Intrinsic and Rho-dependent termination cooperate for efficient transcription termination at 3' untranslated regions.

The intrinsic, and the Rho-dependent mechanisms of transcription termination are conserved in bacteria. Generally, the two mechanisms have been illustrated as two independent pathways occurring in the 3' ends of different genes with contrasting requirements to halt RNA synthesis. However, a majority of intrinsic terminators terminate transcription inefficiently leading to transcriptional read-through.

Copper, Zinc-Superoxide Dismutase from Clinically Isolated Escherichia coli: Cloning, Analysis of sodC and Its Possible Role in Pathogenicity.

Superoxide dismutase has been discovered within the periplasm of several Gram-negative pathogens. We studied the Cu,Zn-SOD enzyme in Escherichia coli isolated from clinical samples (stool samples) collected from patients suffering from diarrhea. Antibiogram studies of the isolates were carried out to determine the sensitive and resistant strains.

Biochemical characterization of a recombinant Swainsona canescens calcium-dependent protein kinase (ScCPK1).

Calcium-dependent protein kinases (CPKs) constitute a unique family of kinases involved in many physiological responses in plants. Biochemical and kinetic properties of a recombinant Swainsona canescens calcium-dependent protein kinase (ScCPK1) were examined in this study. The optimum pH and temperature for activity were pH 7.

Changes in embryonic protein profile and economic characters of Bombyx mori (Lepidoptera:Bombycidae) following UV irradiation.

Eggs of B. mori were irradiated with UV (254.4 nm wavelength) for different durations.
