Imaging properties of axicon in a scanning optical system

Rieko Arimoto, Caesar Saloma, Takuo Tanaka, Satoshi Kawata
1992 Applied Optics  
The imaging properties of a scanning optical system that incorporates an axicon are presented. Beamshape characteristics including the axial distribution of the J 0 beam and its control and aberration effects arising from off-axis illumination are experimentally studied. These parameters are relevant when the axicon is used in an imaging system operating in the beam-scanning mode. The J 0 pattern produced by a blazed axicon transmittance grating is also presented.

Pleuropulmonary blastoma in extrapulmonary lung tissue: A case report

Mio Tanaka, Rieko Ijiri, Mariko Yoshida, Misa Yoshida, Hiroshi Take, Kumiko Nozawa, Noriko Aida, Hiroaki Goto, Yukichi Tanaka
2014 Journal of Pediatric Surgery Case Reports  
We report a case of pleuropulmonary blastoma (PPB) occurring in a very unusual location, extrapulmonary lung tissue, as possible extralobar pulmonary sequestration. The patient was a girl aged two years and six months with respiratory symptoms. Infection of a congenital pulmonary malformation was suspected based on computed tomography findings. The operative findings revealed a partly adherent mass located between the upper and middle right lobes, and a feeding vessel. Histological analysis

A small portion of normal-looking pulmonary tissues was confirmed in the subcapsular area of the mass, suggesting that the tumor originated in extrapulmonary lung tissue. The patient underwent postoperative chemotherapy. No recurrence or metastasis of the PPB has occurred during the 10-year follow-up. When considering the treatment options for an extralobar pulmonary lesion, the possibility of PPB should be considered, although its occurrence may be extremely rare.

Pitx1 expression in developing and regenerating axolotl limbs

Takashi SHIMOKAWA, Satoru YASUTAKA, Rieko KOMINAMI, Shigenori TANAKA, Harumichi SHINOHARA
2008 Okajimas Folia Anatomica Japonica  
The expression of the homeobox transcription factor Pitx1 was investigated in the Mexican axolotl (Ambystoma mexicanum) during limb development and regeneration by whole-mount mRNA in situ hybridizations. This clone shares high amino acid identity with Pitx1 from other vertebrates (92% Xenopus; 87% chick; 75% human and mouse) within the region isolated. In the developing limbs, Pitx1 was expressed in hindlimb mesenchyme, as has been reported in other species. The expression pattern in the

Our observations suggest two roles of Pitx1 in the axolotl: one is to determine the hindlimb pattern during development, and the other that relates to proliferation of regenerating tissues without regard to fore-or hindlimb.

Four Types of Attitudes Towards Foreign Workers: Evidence from a Survey in Japan

Frances McCall Rosenbluth, Rieko Kage, Seiki Tanaka
2016 Social Science Research Network  
Employing a survey method to explore attitudes towards foreign workers in Japan, we uncover evidence that upends the conventional wisdom that "socio-tropic values" are anchored in perceptions of threat. Building a new typology that differentiates among native-born citizens who value or fear foreigners for their expected effects on the economic and cultural dimensions, we find that Japanese corporate managers, especially in labor-scarce sectors, appreciate the positive effects of foreign labor
more » ... re than they dread the dilution of cultural beliefs and practices that underpinned the fabled Japanese labor force. This finding is significant because, even without becoming whole-hearted multi-culturalists, a positive disposition of Japanese corporate management towards foreign workers could signal a shift in policy. Although ethnocentrists remain in Japan (as elsewhere), the views of the business community are likely to have more bearing on government policy than those of other groups. ⇤ The authors are listed in alphabetical order. We would like to thank Michael Thies for his comments.

2021 Journal of Oleo Science  
This study aimed to compare the distribution of vitamin E analogs, particularly α-tocopherol and δ-tocopherol, in mice fed with a normal diet and a high-fat and high-sucrose diet separately. We used male C57BL/6JJcl strain mice, which were divided into six groups (control [C], Cα, Cδ, high-fat and high-sucrose [H], Hα, and Hδ groups) and bred for 4 weeks. The additional quantity of α-tocopherol or E-mix D (containing 86.7% δ-tocopherol) into diet was 800 mg/kg diet. The final body weight was

Similar results were obtained in epididymal fat weight. Moreover, α-tocopherol was mainly distributed in the liver in both the Cα group and Hα group, whereas δ-tocopherol mostly accumulated in the epididymal fat, in both the Cδ group and Hδ group. Also, δ-tocopherol was detected in all tissues in both groups. Both the α-tocopherol and δ-tocopherol levels in the epididymal fat were significantly lower in the H group than in the C group. In conclusion, our results suggest that a portion of δ-tocopherol was incorporated into the adipose tissue by chylomicron before arriving at the liver, and then it is metabolized in the liver.

2014 Anaerobe  
Periodontitis arises from a biofilm consisting of gram-negative anaerobic rods and spirochetes. Porphyromonas gingivalis, Treponema denticola, and Tannerella forsythia, termed the Red complex, have been co-isolated with high frequency from chronic periodontitis lesions, and these microorganisms are thought to be major pathogens of the disease. Coaggregation is an important strategy in the colonization of dental plaque biofilm by these bacteria. In the present study, we investigated the

T. denticola ATCC 35405 coaggregated with T. forsythia, reaching a plateau at approximately 60 min. This coaggregation was inhibited by heat treatment of T. denticola ATCC 35405, but not of T. forsythia. Disaccharides such as sucrose, maltose, and lactose inhibited coaggregation by approximately 50%. The coaggregation reaction varied among T. denticola strains. There was somewhat less coaggregation between T. denticola ATCC 33520 and T. forsythia than between T. denticola ATCC 35405 and T. forsythia, although this difference was not statistically significant; T. denticola ATCC33521 showed a trace level of coaggregation with T. forsythia. The magnitude of coaggregation among the three T. denticola strains was proportional to their dentilisin activities. Inactivation of dentilisin abolished coaggregation activity, but inactivation of the major outer sheath protein did not. Phenylmethylsulfonyl fluoride (PMSF) also did not affect coaggregation. These results indicate that dentilisin is involved indirectly in the coaggregation between T. denticola and T. forsythia, because its proteolytic activity is not required, possibly via ligand maturation. 2

Transient Hemolysis during Growth Hormone Therapy

Toru Momoi, Rieko Tanaka, Akira Yoshida, Mitsuyoshi Okumura, Shinji Yamakura, Hidefumi Hiramatsu, Ayumi Uematsu, Chutaro Yamanaka, Masahiko Kawai
1995 Clinical Pediatric Endocrinology  
Two boys with idiopathic growth hormone (GH) deficiency developed hemolysis at 2 months and 4 months, respectively, after the start of GH replacement therapy. The hemolysis was subclinical and was noticed on routine laboratory tests. Although there was no direct evidence for a causal relationship between the incident and GH therapy, no other couse was found in these 2 patients. There were no family histories suggesting hemolysis, although we did not perform tests among the family members of

Early-onset neonatal hyperkalemia associated with maternal hypermagnesemia: a case report

Kenichi Tanaka, Hiroko Mori, Rieko Sakamoto, Shirou Matsumoto, Hiroshi Mitsubuchi, Kimitoshi Nakamura, Masanori Iwai
2018 BMC Pediatrics  
Neonatal nonoliguric hyperkalemia (NOHK) is a metabolic abnormality that occurs in extremely premature neonates at approximately 24 h after birth and is mainly due to the immature functioning of the sodium (Na + )/potassium (K + ) pump. Magnesium sulfate is frequently used in obstetrical practice to prevent preterm labor and to treat preeclampsia; this medication can also cause hypermagnesemia and hyperkalemia by a mechanism that is different from that of NOHK. Herein, we report the first case
more » ... f very early-onset neonatal hyperkalemia induced by maternal hypermagnesemia. Case presentation: A neonate born at 32 weeks of gestation developed hyperkalemia (K + 6.4 mmol/L) 2 h after birth. The neonate's blood potassium concentration reached 7.0 mmol/L 4 h after birth, despite good urine output. The neonate and his mother had severe hypermagnesemia caused by intravenous infusion of magnesium sulfate given for tocolysis due to pre-term labor. Conclusion: The early-onset hyperkalemia may have been caused by the accumulation of potassium ions transported through the placenta, the shift of potassium ions from the intracellular to the extracellular space in the infant due to the malfunctioning of the Na + /K + pump and the inhibition of renal distal tube potassium ion secretion, there is a possibility that these mechanisms were induced by maternal and fetal hypermagnesemia after maternal magnesium sulfate administration. Because neonatal hyperkalemia poses a significant risk for the development of life-threatening cardiac arrhythmia, this case highlights the necessity of maternal blood magnesium monitoring during magnesium sulfate administration and neonatal blood potassium monitoring when there is severe maternal hypermagnesemia at delivery.

1998 Proceedings of the 11th annual ACM symposium on User interface software and technology - UIST '98  
This paper presents an interaction technique for walkthrough in virtual 3D spaces, where the user draws the intended path directly on the scene, and the avatar automatically moves along the path. The system calculates the path by projecting the stroke drawn on the screen to the walking surface in the 3D world. Using this technique, the user can specify not only the goal position, but also the route to take and the camera direction at the goal with a single stroke. A prototype system is tested
