As an emerging interdisciplinary field, oncofertility bridges oncology, reproductive endocrinology, and infertility with the goal of expanding reproductive options for women with cancer. Oncofertility is currently gaining significant attention from professionals in many related fields and is undergoing considerable scrutiny in part because of the many compelling ethical dilemmas it raises. To i...
Background: When actual measurement of stature cannot be done, other surrogate parameters can be used to predict stature. Stature in clinical medicine and in the field of scientific research can be easily estimated using various anthropometric parameters like arm span, knee height, foot length and breadth etc. Arm span has been proven to be one of the most reliable predictors. Thus this study w...
The preceding fourteen chapters have been written at a good time to take stock of the field of Gamma Ray Bursts (GRBs). The extraordinary discoveries made over the last decade or so about a phenomenon that has been around for over four decades seem to have attained a mature state. Thousands of bursts have been observed, classified and followed up and it is now the special and rare cases, that a...
Nitrogen rate and time of application are among the major abiotic factors limiting productivity maize. The research was, therefore, carried out to examine response two maize varieties (Omankwa Pioneer hybrid) four different times N : P K 15 fertilizer during growing season in Ghana. experiment was arranged a randomized complete block design with eight treatment combinations three replications. ...
Ordered mesoporous carbon as an efficient and reversible adsorbent for the adsorption of fullerenes.
An ordered mesoporous carbon, CMK-3, was synthesized using a mesoporous siliceous material, SBA-15, as the template. CMK-3 was characterized and used for the adsorption of fullerenes C60 and C70. It was found that the adsorption capacity of CMK-3 is 4 times higher than that of activated carbon. The adsorption equilibrium isotherms of C60 and C70 on CMK-3 were studied for both single and binary ...
[Purpose] The aim of this study was to investigate the associations between self-reported and valid performance-based measures of functional capacity in individuals with chronic stroke. [Subjects and Methods] Self-reported measures of functional capacity of 31 individuals with chronic stroke were assessed by the Duke Activity Status Index scores, whereas performance-based measures were assessed...
pH-responsive megagates have been fabricated around mesoporous silica material SBA-15 in order to mechanize the mesopores. These megagates remain closed in neutral conditions, but open at pH 5. The capping components of the megagates were designed to be capable of controlling pores up to 6.5 nm in diameter. Selectivity of payloads with different sizes can be achieved through the use of differen...
IL-15 is critical for generation of multiple lymphoid subsets. Recent data have demonstrated a unique aspect of responses to IL-15, in that cells bearing the IL-15Ralpha chain can bind soluble IL-15 and "transpresent" the cytokine to other cells, allowing the latter to respond to IL-15. However, it is unclear whether IL-15 is normally secreted and then becomes bound to surface IL-15Ralpha on by...
Interleukin-15/T(IL-15) is a growth factor that utilizes IL-2 receptor (IL-2R) components in addition to its private binding protein IL-15R(alpha) in T-cells. Here, we report that IL-15 induces mast cell proliferation in the absence of IL-2R alpha and beta. Using transfectants of these cells with a cytoplasmic-truncated mutant of gamma(c), we demonstrated that IL-15 signaling in mast cells does...
