The emergence of hard X-ray free electron lasers (XFELs) enables new insights into many fields of science. These new sources provide short, highly intense, and coherent X-ray pulses. In a variety of scientific applications these pulses need to be strongly focused. In this article, we demonstrate focusing of hard X-ray FEL pulses to 125 nm using refractive x-ray optics. For a quantitative analys...
The objective of our study was to compare the characteristics of the corpus luteum (CL) formed after ovulation of the dominant follicle (DF) of the first follicular wave (W1) and those of the CL formed after ovulation of the DF of the second (induced) follicular wave (W2). Non-lactating Holstein cows were used for this study. In Experiment 1, cows were treated with PGF2α and GnRH on days 6 and ...
Progression of preantral follicle development is essential to further follicle maturation and ovulation, but there are few models for studying the regulation of preantral follicle survival and growth. We have evaluated preantral follicle survival in vivo and in vitro, and have developed a serum-free rat follicle culture system that can be used to characterize the regulation of preantral follicl...
The objective of this study was to characterize the patterns of ovarian follicular waves, and FSH and P4 concentration during estrous cycle in Thai native cattle (Bos indicus). Transrectal ultrasound examination of ovaries was performed daily using a 7.5 MHz transducer and blood samples were collected after the ultrasound examination during May to August, 2010. There were 1-, 2or 3-follicular w...
The skin is a complex stratifi ed organ which acts not only as a permeability barrier and defense against external agents, but also has essential thermoregulatory, sensory and metabolic functions. Due to its high versatility and activity, the skin undergoes continuous selfrenewal to repair damaged tissue and replace old cells. Consequently, the skin is a reservoir for adult stem cells of diff e...
BACKGROUND Primordial follicular depletion has thought to be a common adverse effect of chemotherapy especially for female of reproductive age. The study aimed to evaluate the protective effect of rapamycin on the primordial follicles and its potential mechanism for patients receiving chemotherapy. METHODS 8-week old BALB/c female mice were randomly assigned into four groups (control; rapamyc...
We study the emergence of quasiperiodic Bloch wave functions in quasicrystals, employing one-dimensional Fibonacci model as a test case. find that despite fact are not eigenfunctions themselves, superpositions relatively small numbers nearly degenerate give rise to extended functions. These possess structure earlier ancestors underlying potential, and it is often possible obtain different aroun...
