OBJECTIVE To examine decreases over time in cigarette smoking prevalence and intensity among American students in 8th, 10th, and 12th grades. METHODS Data from Monitoring the Future on students' smoking, across four measures of differing intensity of smoking, are compared over time and across grade levels. Data are available since 1975 for 12th graders and since 1991 for 8th and 10th graders....
Recurring chromosomal translocations observed in human leukemia often result in the expression of fusion proteins that are DNA-binding transcription factors. These altered proteins acquire new dimerization properties that result in the assembly of inappropriate multimeric transcription complexes that deregulate hematopoietic programs and induce leukemogenesis. Recently, we reported that the fus...
During the life cycle of Chlorella vulgaris Beijerinck var vulgaris fa. vulgaris growing synchronously, the specific activity of ornithine decarboxylase peaked at the 2nd hour of the cycle, whereas that of arginine decarboxylase changed only slightly, increasing towards the end of the cycle. The endogenous level of putrescine and spermidine on a per cell basis increased gradually up to the 8th ...
OBJECTIVE To evaluate the efficacy of biofeedback-assisted pelvic floor muscle training (PFMT) for urinary incontinence and to determine the patient characteristics predictive of success. METHODS Clinical and physiologic data of 86 patients with urinary incontinence who had received biofeedback-assisted PFMT were analyzed retrospectively. The clinical response was determined to be a success (...
The aim of this study was to investigate the repair effect of human acellular amniotic membrane (HAAM) loading bone marrow mesenchymal stem cells (BMSCs) on articular cartilage defect in rabbits. Rabbit BMSCs were isolated and cultured, and they were then inoculated on HAAM to prepare the complex of HAAM and BMSCs. Twenty-four rabbits were randomly divided into groups A and B, with 12 animals i...
Leprosy was rare in Europe during the Roman period, yet its prevalence increased dramatically in medieval times. We examined human remains, with paleopathological lesions indicative of leprosy, dated to the 6th-11th century AD, from Central and Eastern Europe and Byzantine Anatolia. Analysis of ancient DNA and bacterial cell wall lipid biomarkers revealed Mycobacterium leprae in skeletal remain...
