In this scientific research, for the first time, the removal of radioactive strontium-90 (90Sr) by γ-MnO2-AgA zeolite as a novel nanocomposite adsorbent was accomplished under different conditions such as pH, temperature, adsorbent amount and the contact time that are examined from drinking water of Ramsar city and monitored via Ultra Low-Level Liquid Scintillation Counting (LSC) technique. Pri...

The balance between stomatal and mesophyll conductance has been reported to directly influence intrinsic water-use efficiency (WUEi), but it is unclear whether variations in limitations (lsc lm, respectively) affect WUEi during soil drought rewatering. Limitations (lsc, lm biochemical limitation, lb) were measured Manchurian ash (Fraxinus mandshurica Rupr.) Mongolian oak (Quercus mongolica Fish...

Protein evolution includes the birth and death of structural motifs. For example, a zinc finger or a salt bridge may be present in some, but not all, members of a protein family. We propose that such transitions are manifest in sequence phylogenies as concerted shifts in substitution rates of amino acids that are neighbors in a representative structure. First, we identified rate shifts in a qua...

Within the Pumwani sex worker cohort, a subgroup remains seronegative, despite frequent exposure to HIV-1; some of them seroconverted several years later. This study attempts to identify viral variations in 5'LTR-leader sequences (5'LTR-LS) that might contribute to the late seroconversion. The 5'LTR-LS contains sites essential for replication and genome packaging, viz, primer binding site (PBS)...

Drawing on the dual-systems theory (DST), this study proposes a research model that focuses how characteristics of key opinion leader influence consumers’ purchase intention in live streaming commerce (LSC). We collected data through questionnaire surveys from samples consumers China (N = 467), which indicated leader’s (i.e., attractiveness, trustworthiness, expertise) are all positively relate...

Background: Liquid scintillation counters (LSCs) are commonly used as an analytical method for detecting 222Rn in groundwater because they involve a simple sample pretreatment and allow high throughout with an autosampler. The Quantulus 1220 is the best-selling LSC in Korea, but its production was stopped. Recently, a new type of LSC, the 300SL, was introduced. In this study, the 300SL was comp...

BACKGROUND Acute myeloid leukemia (AML) is a heterogeneous clonal disorder presenting with accumulation of proliferating undifferentiated blasts. Xenograft transplantation studies have demonstrated a rare population of leukemia-initiating cells called leukemic stem cells (LSCs) capable of propagating leukemia that are enriched in the CD34+/CD38- fraction. LSCs are quiescent, resistant to chemot...

Determination of 241Pu is an essential issue for radiation protection, as it the precursor some nuclides with high radiotoxicity. a low energy beta emitter, which makes its measurement more challenging than that Pu alpha emitters. The most widely used method liquid scintillation counting (LSC). In this method, assessment radiochemical yield done by measuring sample spectrometry before being lix...

OBJECTIVE To describe a rare pathology, the liposarcoma of the spermatic cord (LSC), and discuss its diagnosis and treatment. MATERIALS AND METHODS We report a case of well-differentiated LSC in a 61-year-old man. The main complaint was painless enlargement in the right inguinoscrotal area that appeared 6 months prior to presentation. Ultrasonography showed a heterogeneous and hyperechogenic ...

Accurate monitoring of tumor dynamics and leukemic stem cell (LSC) heterogeneity is important for the development of personalized cancer therapies. In this study, we experimentally induced distinct types of leukemia in mice by enforced expression of Cbx7. Simultaneous cellular barcoding allowed for thorough analysis of leukemias at the clonal level and revealed high and unpredictable tumor comp...
