Focus movement distance per pulse dependence of electrical conductivity and diameter of diamond internal modification induced by picosecond laser.

Internal and local modifications via ultrashort pulsed laser illumination to diamond are promising for manufacturing diamond electronic devices. The relationship between the diameter/electrical conductivity of modified regions and the laser fluence distribution was investigated. Picosecond laser illumination without scanning the laser focus fabricated short modified regions in diamond.

Local control of optical absorption properties of glass using precipitation of gold nanoparticles via gold sphere movement driven by laser.

Glass embedded with metal nanoparticles is a promising material necessary for optical devices because of its absorption properties associated with the surface plasmon resonance (SPR) of metal nanoparticles. We demonstrated that continuous-wave laser illumination of the metal sphere in glass migrates the metal sphere and dopes the migration trajectory. In this study, we have attempted to locally control the absorption properties of borosilicate glass via gold nanoparticle precipitation using gold sphere migration.

Myeloid leukemoid reaction after initial azacitidine therapy for chronic myelomonocytic leukemia.

The development of myeloid leukocytosis in leukemia patients during antileukemic treatment requires a differential diagnosis between myeloid leukemoid reaction and leukemia progression. We herein report the case of an 80-year-old Japanese man with chronic myelomonocytic leukemia (CMML) who developed marked myeloid leukocytosis (36.3 × 10/L) with 32.

Does time of CCI measurement affect the evaluation of platelet transfusion effectiveness?

The measurement of corrected count increment at 1-h post-transfusion (CCI-1 h) of platelet concentrate (PC) transfusion is recommended, but in the revised Japanese Guideline (2017) it was changed to "after 10-min to 1-h", following the revision of the guidelines from Western countries. Here, we aimed to investigate on the feasibility to apply the CCI measured at 10-min or 30-min post-transfusion as the surrogate of CCI-1 h. Peripheral blood was collected at 10-min, 30-min and 1-h post-transfusion of PC and the effectiveness of the transfusion was analyzed based on the CCI.

Azacitidine-associated haemorrhagic enteritis in a case of myelodysplastic syndrome: A case report.

What Is Known And Objective: 5-Azacitidine (AZA) is an agent widely used to treat myelodysplastic syndrome (MDS).

Case Description: We herein report an 83-year-old woman diagnosed with MDS who was treated with AZA. She tolerated the first cycle of AZA; however, severe adverse events involving haemorrhagic enteritis with multiple intestinal ulcers developed after the second and third cycles.

Clarification of fast metal sphere movement in glass.

In this study, metal spheres were implanted into glass by continuous-wave (CW) laser illumination, which manipulated the metal sphere inside the glass. The spheres moved at approximately 100 mm/s, which is 100 times faster compared to conventional movement. The movement mechanism was clarified by in situ, cross-sectional, and microscopic observations.

Multiple HLA-matched platelet transfusions for a single patient with broad anti-HLA antibodies: a case report.

The efficacy of 30 platelet concentrate (PC) products transfused to a patient with myelodysplastic syndrome (MDS) was evaluated by calculating the 1-hour post-transfusion corrected count increment (1h-CCI). Of the 30 transfusions, all HLA-A/B-matched, the cross-match (CM) test was negative in 23 (CM(-)-PC) and weakly positive (CM(+)-PC) in 2, and the CM test was not conducted in 5 (non-CM-PC). The effective rate was higher with CM(-)-PC compared to non-CM-PC (82.

Compositional redistribution in CaO-AlO-SiO glass induced by the migration of a steel microsphere due to continuous-wave-laser irradiation.

A high-power continuous-wave (CW) laser was used to move a steel microsphere through a CaO-AlO-SiO glass block at room temperature along a trajectory toward the laser source. A compositional analysis revealed that the CaO concentration in the glass decreased at the center of the microsphere's trajectory but increased in the area adjacent to it; the SiO concentration showed an opposite trend while the AlO concentration did not change. Further, the compositional difference between the center and the area adjacent to the microsphere trajectory depends on the velocity of the microsphere, which is controllable by tuning the laser power.

Experimental and theoretical study on the driving force and glass flow by laser-induced metal sphere migration in glass.

Light is able to remotely move matter. Among various driving forces, laser-induced metal sphere migration in glass has been reported. The temperature on the laser-illuminated side of the sphere was higher than that on the non-illuminated side.

Picosecond optical vortex pulse illumination forms a monocrystalline silicon needle.

The formation of a monocrystalline silicon needle by picosecond optical vortex pulse illumination was demonstrated for the first time in this study. The dynamics of this silicon needle formation was further revealed by employing an ultrahigh-speed camera. The melted silicon was collected through picosecond pulse deposition to the dark core of the optical vortex, forming the silicon needle on a submicrosecond time scale.

Dialysis and quality of dialysate in southeast asian developing countries.

Background: The number of dialysis patients has been increasing in Southeast Asia, but statistical data about these patients and on the quality of dialysates in Southeast Asian dialysis facilities are still imprecise. For this study, dialysis-related statistical data were collected in Southeast Asia.

Methods: A survey of the quality of dialysates was carried out at 4 dialysis facilities in Vietnam and Cambodia.

Moving force of metal particle migration induced by laser irradiation in borosilicate glass.

We optically manipulated a metal particle in borosilicate glass. The glass in the neighborhood of the laser-heated metal particle softened; hence, the metal particle was able to migrate in the glass. In this letter, the driving force of the metal particle toward the light source in the glass provided by laser illumination was investigated.

Metal particle manipulation by laser irradiation in borosilicate glass.

We propose a new technique of manipulating a metal particle in borosilicate glass. A metal particle that is heated by laser illumination heats the surrounding glass by radiation and conduction. A softened glass enabled metal particle migration.

The effect of micronscale anisotropic cross patterns on fibroblast migration.

Fabrication of arbitrary polymer patterns for cell study by two-photon polymerization process.

Topographically patterned surfaces are known to be powerful tools for influencing cellular functions. Here we demonstrate a method for fabricating high aspect ratio ( approximately 10) patterns of varying height by using two-photon polymerization process to study contact guidance of cells. Ridge patterns of various heights and widths were fabricated through single laser scanning steps by low numerical aperture optics, hence at much higher processing throughput.

The subjects were 28 maintenance hemodialysis (HD) patients who had remained in ABD state in spite of no administration of vitamin D(3) since HD induction (15 males and 13 females;12 diabetic patients and 16 non-diabetic patients). The mean age was 61.

Molecular confirmation of transmission route of Staphylococcus intermedius in mastoid cavity infection from dog saliva.

We report a case of infection of a mastoid cavity after mastoidectomy had been performed for chronic otitis media with cholesteatoma. The infection was caused by Staphylococcus intermedius after a pet dog had licked the patient's ears. Bacterial strains from the dog's saliva and the otorrhea in the patient were confirmed to be identical by pulsed-field gel electrophoresis analysis.
