Multifunctional optical correlator for picosecond ultraviolet laser pulse measurement.
Appl Opt
PUBLISHED: 11-18-2014
Show Abstract
Hide Abstract
A compact multifunctional optical correlator system for pulse width measurement of ultrashort ultraviolet (UV) pulses has been designed and experimentally demonstrated. Both autocorrelation and cross-correlation functions are measured using a single nonlinear crystal, and the switching between two measurements requires no adjustment of phase matching and detector. The system can measure UV pulse widths from sub-picoseconds to 100 ps, and it involves no auxiliary pulse in the measurement. The measurement results on a burst-mode picosecond UV laser show a high-quality performance on speed, accuracy, resolution, and dynamic range. The proposed correlator can be applied to measure any ultrashort UV pulses produced through sum-frequency generation or second-harmonic generation.

Hide Abstract
Here we report gastric cancer accompanied by bone marrow carcinomatosis in a patient for whom long-term chemotherapy was enabled by early pain-relief therapy. A 45-year-old man was admitted to our hospital because of back pain associated with multiple spinal tumors in June 2011. Blood tests showed a trend toward disseminated intravascular coagulation(DIC) and gastric cancer was suspected as the primary lesion. Because pain was severe, emergency pain relief was provided by flurbiprofen axetil and a continuous subcutaneous infusion of fentanyl citrate. After bone marrow examination gave a diagnosis of poorly differentiated adenocarcinoma, we performed sequential methotrexate(MTX)and 5-fluorouracil(5-FU)therapy. The therapy successfully decreased tumor marker levels, and alkaline phosphatase and lactate dehydrogenase levels normalized. Finally, gastric cancer accompanied by bone marrow carcinomatosis was diagnosed. Because the patient had anxiety and spiritual pain from the time of admission, psychiatric care was also required. In November 2011, the tumor recurred, and we switched therapy to a combination of S-1 and cisplatin. The patient's pain was controlled by combined treatment with a fentanyl patch and etodolac, and he was discharged in December 2011. However, severe pain recurred and pain therapy was continued. DIC developed in February 2012 and transiently resolved after resuming combination therapy with MTX and 5-FU; however, it subsequently recurred, leading to the patient's death in May 2012.

SR-PSOX/CXCL16 plays a critical role in the progression of colonic inflammation.
Gut
PUBLISHED: 04-06-2011
Show Abstract
Hide Abstract
Inflammatory bowel disease (IBD) is initiated and perpetuated by a dysregulated immune response to unknown environmental antigens such as luminal bacteria in genetically susceptible hosts. SR-PSOX/CXCL16, a scavenger receptor that binds phosphatidylserine and oxidised lipoprotein, has both phagocytic activity and chemotactic properties. The aim of this study was to investigate the role of SR-PSOX/CXCL16 in patients with IBD and experimental murine colitis.

Role of heat shock protein 47 in intestinal fibrosis of experimental colitis.
Biochem. Biophys. Res. Commun.

Show Abstract
Hide Abstract
Intestinal fibrosis is a clinically important issue of inflammatory bowel disease (IBD). It is unclear whether or not heat shock protein 47 (HSP47), a collagen-specific molecular chaperone, plays a critical role in intestinal fibrosis. The aim of this study is to investigate the role of HSP47 in intestinal fibrosis of murine colitis.

Hide Abstract
Tacrolimus is a novel immunomodulator for inflammatory bowel diseases. Immunosuppressive effects of tacrolimus on T cells are well known; however, the effects of tacrolimus on macrophages remain unclear. The aim of this study was to investigate the effects of tacrolimus on activated macrophages and to examine its efficacy in murine colitis models.

Hypnotic and sleep quality-enhancing properties of kavain in sleep-disturbed rats.
J. Pharmacol. Sci.
PUBLISHED: 10-31-2009
Show Abstract
Hide Abstract
The present study was performed to investigate the effects of kavain on the sleep-wake cycle in comparison with that of rilmazafone and diphenhydramine using sleep-disturbed rats. Electrodes for the electroencephalogram (EEG) and electromyogram (EMG) were implanted into Wistar rats. Total awake time, non-rapid eye movement (non-REM) sleep and rapid eye movement (REM) sleep were measured for 6 h. Kavain and rilmazafone showed a significant shortening in sleep latency, decreased awake time, and increased non-REM sleep time. On the other hand, significant shortening of the sleep latency was observed following the administration of diphenhydramine, while no effects were observed on the awake and non-REM sleep time. Moreover, kavain showed a significant increase in delta activity during non-REM sleep in sleep-disturbed rats, whereas a significant decrease in delta power during non-REM sleep was observed with rilmazafone. These results clearly indicate that kavain is a compound with not only hypnotic effects, but also sleep quality-enhancement effects.

Hide Abstract
Dementia is a neurologic disorder presenting memory impairment as a main symptom. It is well known that patients often complain of sleep disturbance as an associated symptom in dementia. It has been reported that donepezil caused sleep disturbance, but little is known about the effect of galantamine on sleep-wake patterns. In the present study, we investigated the effects of anti-dementia drugs on sleep-wake patterns in sleep-disturbed rats. Single administration of donepezil and galantamine caused no significant effect on sleep-wake patterns at doses used in the present study in rats. On the other hand, piracetam caused a significant decrease in sleep latency at a dose of 500 mg/kg. Next, we examined the changes in sleep-wake patterns from repeated administration of donepezil, galantamine and piracetam. Donepezil caused significant increases in sleep latency and total wake time and decrease in total non-rapid eye movement sleep time at a dose of 1 mg/kg. However, galantamine caused no effect on sleep-wake patterns. Piracetam caused significant decreases in sleep latency and total wake time at a dose of 500 mg/kg. From these results, it is concluded that donepezil deteriorated sleep disturbance, and piracetam caused somnolence. In addition, galantamine showed no influence on the sleep.

Effects of narcotics, including morphine, on visual evoked potential in rats.

Hide Abstract
The side effects of narcotics, including morphine, on the visual system are still unclear; therefore, the present study was undertaken to examine the effects of narcotics on the visual system at each antinociceptive dose by using the evoked potential (VEP) in rats. Morphine (2 or 5 mg/kg) caused a significant increase in the amplitude of early and late VEP components (P(1)-N(1), N(1)-P(2), P(3)-N(3) and N(3)-P(4)). Fentanyl (0.02 mg/kg) also showed a significant increase in the amplitude of late VEP components (P(3)-N(3), N(3)-P(4)). The effects of morphine and fentanyl on VEP components were antagonized by naloxone (1 mg/kg). On the other hand, (+/-)-pentazocine (20 mg/kg) reduced the amplitude of the late VEP component (N(3)-P(4)), and this effect was not antagonized by naloxone. Butorphanol showed no significant changes in early and late VEP components. In conclusion, morphine stimulated the retino-geniculate-cortex pathway and the thalamus-cortical circuit through the opioid receptors, and fentanyl stimulated the thalamus-cortical circuit through the opioid receptors. It can therefore be assumed that VEP is a useful tool for examining the side effects of drugs, including narcotics, on the visual system.

What is Visualize?

JoVE Visualize is a tool created to match the last 5 years of PubMed publications to methods in JoVE's video library.

How does it work?

We use abstracts found on PubMed and match them to JoVE videos to create a list of 10 to 30 related methods videos.

Video X seems to be unrelated to Abstract Y...

In developing our video relationships, we compare around 5 million PubMed articles to our library of over 4,500 methods videos. In some cases the language used in the PubMed abstracts makes matching that content to a JoVE video difficult. In other cases, there happens not to be any content in our video library that is relevant to the topic of a given abstract. In these cases, our algorithms are trying their best to display videos with relevant content, which can sometimes result in matched videos with only a slight relation.
