The aim of our in vitro experiments was to examine if IGF binding protein (IGFBP)-3 is involved in control of bovine ovarian secretory activity. For this purpose we performed the transfection of bovine granulosa cells with cDNA sense and antisense constructs increasing or inhibiting IGFBP-3 synthesis. The release of IGFBP-3, progesterone, oxytocin, IGF-I and prostaglandins F (PGF) and E (PGE) b...

Neonatal hyperthyroidism has been thought to result from transplacental passage of long-acting thyroid stimulator (L.A.T.S.) from a mother with Graves's disease. A case is presented here in which no L.A.T.S. was detected in the mother or neonate but another immunoglobulin, L.A.T.S. protector, a specific human thyroid stimulator, was shown to be present in the mother's serum. This stimulator may...

This paper presents an electrical stimulator with four high-voltage-tolerant output channels for cochlear implant in a 0.18μm low-voltage CMOS process. As the maximum stimulation voltage can be as high as 7 V, this stimulator only needs one single supply voltage of 1.8 V. To implement this stimulator in a low-voltage CMOS process, the dynamic bias technique and stacked MOS configuration are use...

We have found a new growth stimulator for bifidobacteria in the culture broth of Propionibacterium freudenreichii ET-3. The bifidogenic growth stimulator (BGS) was purified by Diaion HP-20 column chromatography and preparative HPLC. Spectroscopic methods including 1H-NMR, UV, and LC-ESI-MS experiments indicated that the chemical structure of the bifidogenic growth stimulator was 1,4-dihydroxy-2...

failure to respond adequately to standard protocols and to recruit adequate follicles is called ‘poor response’. this results in decreased oocyte production, cycle cancellation and, overall, is associated with a significantly diminished probability of pregnancy. it has been shown that ovarian reserve tests, such as basal fsh, antimullarian hormone (amh), inhibin b, basal estradiol, antral folli...

background: ovarian fibroma is the most common benign solid tumor of the ovary, which is often difficult to diagnose preoperatively. the choice treatment for ovarian fibroma is surgical removal, but discussions for the operative approach, laparoscopic or open, in the literature seem to be scant. case presentation: we presented a unique clinical experience of laparoscopic approach to a case of 1...

Arterial baroreflexes may regulate resistance vessels supplying glucose to skeletal muscle by modulating efferent sympathetic nervous system activity. We hypothesized that selective manipulation of baroreflex activity through electrical carotid sinus stimulation influences insulin sensitivity by changing muscular glucose delivery. We enrolled 16 hypertensive patients who responded to treatment ...

This low cost visual stimulator was developed for use in small animal imaging. The stimulator uses a single tri-color LED for each eye and can output red, green, or blue light or any combination of the three. When all three LED colors are illuminated at the same time achromatic light is the output. The stimulator is almost entirely implemented in software with only minimal electronics. The LEDs...
