Sorbitol dehydrogenase (hSDH) and aldose reductase form the polyol pathway that interconverts glucose and fructose. Redox changes from overproduction of the coenzyme NADH by SDH may play a role in diabetes-induced dysfunction in sensitive tissues, making SDH a therapeutic target for diabetic complications. We have purified and determined the crystal(More)
Acupuncture has been reported to affect the autonomic system. Currently, there are no systematic reviews examining the effect of acupuncture on HRV available in the literature. Therefore, the aim of this systematic review was to summarize and critically assess the effects of acupuncture on heart rate variability. We searched the literature using 14(More)
PURPOSE To determine whether early referral to reproductive specialists improves fertility preservation (FP) outcomes and reduces delay in adjuvant treatment in young women with breast cancer. PATIENTS AND METHODS A secondary analysis of a prospective database of patients with breast cancer undergoing ovarian stimulation (OS) for FP by oocyte or embryo(More)
Fertility preservation (FP) is an effort to retain the fertility of cancer patients, and as an emerging discipline, it plays a central role in cancer care. Because of improvement in diagnostic and therapeutic strategies, an increasingly large number of patients are surviving with cancer. FP specialists should make an effort to spread the significance of FP(More)
In this paper, a new microinjection device was constructed by fusing a glass microneedle and a PDMS-based microvalve. The microneedle was fabricated via traditional micropipette pulling. The PDMS-based microvalve regulates the fluid flow in the microchannel and microneedle. The 'ON/OFF' operation of the valve was controlled by manually supplied pneumatic(More)
A microfluidic apparatus capable of creating continuous microscale cylindrical polymeric structures has been developed. This system is able to produce microstructures (e.g. fibers, tubes) by employing 3D multiple stream laminar flow and "on the fly"in-situ photopolymerization. The details of the fabrication process and the characterization of the produced(More)
To predict embryo/oocyte cryopreservation cycle (ECC) outcomes in breast cancer patients stimulated with letrozole and follicle stimulating hormone for fertility preservation based on observed anti-mullerian hormone (AMH) levels and antral follicle counts (AFC). The correlation between AMH and AFC and ECC outcomes were analyzed retrospectively on forty one(More)

A new DNA hybridization analytical method using a microfluidic channel and a molecular beacon-based probe (MB-probe) is described. A stem-loop DNA oligonucleotide labeled with two fluorophores at the 5' and 3' termini (a donor dye, TET, and an acceptor dye, TAMRA, respectively) was used to carry out a fast and sensitive DNA analysis. The MB-probe utilized(More)
PURPOSE To investigate blood oxygenation level-dependent (BOLD) MRI and diffusion-weighted imaging (DWI) at 3 T for assessment of early renal allograft dysfunction. MATERIALS AND METHODS 34 patients with a renal allograft (early dysfunction, 24; normal, 10) were prospectively enrolled. BOLD MRI and DWI were performed at 3 T. R2* and apparent diffusion(More)
