Abstract
OBJECTIVE Today, most individuals with cerebral palsy are adults who need a paediatric-to-adult health care transition. However, many remain in paediatric care for treatment of adult-onset health issues. Therefore, a systematic review based on the 'Triple Aim' framework was performed to determine the status of paediatric-to-adult health care transition for people with cerebral palsy. A comprehensive evaluation of transitional care was proposed for using this framework. It consists of 'experience of care', meaning satisfaction with the care, 'population health', meaning the well-being of patients, and 'cost', meaning cost-effectiveness. METHOD Electronic database (PubMed) searches were performed. The inclusion criteria were original articles published between 1990 and 2020. The search terms used in this study were ('cerebral palsy' AND 'transition to adult health care') OR ('cerebral palsy' AND 'transition'). The study type had to be epidemiological, case report, case-control, and cross-sectional, but not qualitative. The outcomes of the studies were categorised into 'care experience', 'population health', and 'cost', according to the Triple Aim framework. RESULTS Thirteen articles met the abovementioned inclusion criteria. Few studies have examined the effect of the intervention of transition for young adults with cerebral palsy. Participants in some studies had no intellectual disability. Young adults were dissatisfied with the 'care experience', 'population health', and 'cost' and had unmet health needs and inadequate social participation. INTERPRETATION Further transition intervention studies with a comprehensive assessment and proactive involvement of individuals are warranted. The presence of an intellectual disability should be considered.

Abstract
In recent years, Japan has promoted home visits to support older adults, with caregivers playing an important role. However, caregivers generally experience a high frequency of anxiety and depression, and the factors associated with these conditions among home visit caregivers remain unknown. To identify the associated factors, we conducted a questionnaire-based cross-sectional study of home visit caregivers in Tokushima Prefecture, Japan. The survey included caregivers' Hospital Anxiety and Depression Scale;sociodemographic items of patients and caregivers;and caregivers' perceptions of the home care environment, patients, and themselves. The questionnaires were sent to 379 caregivers;203 responded (53.6% response rate), of which 173 were valid (85.2% valid response rate). The prevalence of anxiety and depression was 43.9% and 69.4%, respectively. Multiple logistic regression analysis of factors associated with anxiety and depression showed that stable family finances (OR:0.69, 95% CI:0.48-1.00, p=0.049) and stable caregiver health (OR:0.45, 95% CI:0.30-0.68, p<0.001) were associated with anxiety. Further, stable family finances (OR:0.60, 95% CI:0.38-0.93, p=0.022), stable caregiver health (OR:0.49, 95% CI:0.30-0.81, p=0.005), and stable patient condition (OR:0.51, 95% CI:0.29-0.92, p=0.025) were associated with depression. These findings demonstrate that caregiver wellbeing is essential in home care settings. J. Med. Invest. 70 : 443-449, August, 2023.

Abstract
We investigated the effect of elicitors on xylem differentiation and lignification using a Zinnia elegans xylogenic culture system. Water-soluble chitosan and a fungal elicitor derived from Botrytis cinerea were used as elicitors. Elicitor addition at the start of culturing inhibited tracheary element (TE) differentiation in a concentration-dependent manner, and 30 μg mL(-1) of chitosan or 16.7 μg mL(-1) of the fungal elicitor strikingly inhibited TE differentiation and lignification. Addition of chitosan (at 50 μg mL(-1)) or the fungal elicitor (at 16.7 μg mL(-1)) during the culturing period also inhibited TE differentiation without inhibiting cell division, except for immature TEs undergoing secondary wall thickening. Elicitor addition after immature TE appearance also caused the accumulation of an extracellular lignin-like substance. It appears that elicitor addition at the start of culturing inhibits the process by which dedifferentiated cells differentiate into xylem cell precursors. Elicitor addition during culturing also appears to inhibit the transition from xylem cell precursors to immature TEs, and induces xylem cell precursors or xylem parenchyma cells to produce an extracellular stress lignin-like substance.

Abstract
Progression of the disability of multiple sclerosis (MS) is thought to be related to axonal damage that is seen even in normal appearing white matter (NAWM) of patients' brains. Interferon beta (IFNβ) treatment for MS reduces the frequency of clinical exacerbations and the appearance of new inflammatory demyelinating lesions on magnetic resonance imaging (MRI). However, the effect of IFNβ treatment on axonal damage in MS is not known. The present study aimed to assess the effect of IFNβ on axonal function by comparing the data from localised single voxel proton MR spectroscopy (MRS) performed on eight MS patients given IFNβ-1b treatment and 11 untreated patients. Brain MRI and MRS were performed before the initiation of IFNβ-1b treatment and 24 months after treatment initiation. Levels of N-acetylaspartate (NAA), choline-containing compounds (Cho) and creatine (Cr) were calculated as the areas under their peaks shown on MRS and the ratios of NAA/Cr and Cho/Cr were calculated. In the patients treated with IFNβ-1b there was a significant increase in the ratio of NAA/Cr in NAWM (p=0.028) at 24 months after the initiation of treatment. In contrast, there was no significant change in the NAA/Cr ratio in the untreated patients. These results suggest that IFNβ-1b treatment might recover axonal function in NAWM of MS patients.

Abstract
Sufficient levels of gene expression are required for effective gene therapy. One of the major obstacles in gene therapy is the low transgene expression obtained from currently available vector systems. To address this issue, we employed a transcriptional amplifier strategy in a single construct to enhance transgene expression. In the amplifier vectors (pHi-1 and pHi-2), the strong CMV promoter was used to drive a transcriptional factor, Tat, which could transactivate a second promoter (HIV1 LTR or HIV2 LTR) located in the same construct driving the gene of interest. Using the human interleukin-2 (IL-2) cytokine gene, our data showed that the pHi-1/2 amplifier vectors could produce significantly higher IL-2 levels in human lung cancer cells (A549) and breast cancer cells (MCF-7) than that obtained by directly using the CMV promoter alone. Injection of pHi-2-IL-2-modified Lewis Lung (LL/2) tumor clones led to significantly slower tumor growth and longer survival in mice compared to those injected with either CMV promoter driven IL-2 clones or the parental tumor cells. Our results demonstrated that the transcriptional amplifier-based expression cassettes could be very useful in applications where high levels of gene expression are difficult to achieve.

Abstract
We report 11 cases of thymectomy for myasthenia gravis using propofol and thoracic epidural anesthesia. Considering the influence of nitrous oxide to environment and muscular relaxation of volatile anesthetics, we selected this anesthetic method. By proper sedation with propofol and sufficient analgesia with epidural anesthesia, the hemodynamics during operation was stable and the emergence was rapid. The patients were extubated early after operation except in one case in which oxygenation was not good because of sputum. We conclude that our anesthetic method is useful. Moreover, we applied Fuchu hospital scoring system for prediction of the need of postoperative mechanical ventilation in patients with myasthenia gravis to the present 11 cases. These predictions corresponded well with the results. Therefore Fuchu hospital scoring system is useful for managing these patients by our anesthetic method.

Abstract
Glufosinate ammonium, a broad-spectrum herbicide, causes convulsion in rodents and humans. Because of the structural similarities between glufosinate and glutamate, the convulsion induced by glufosinate ammonium may be ascribed to glutamate receptor activation. Three N-methyl-D-asparate (NMDA) receptor antagonists, dizocilpine, LY235959, and Compound 40, and an alpha-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA)/kainate receptor antagonist, NBQX, were coadministrated with glufosinate ammonium (80 mg/kg, intraperitoneally) in mice. Statistical analyses showed that the NMDA receptor antagonists markedly inhibited the convulsions, while the AMPA/kainate receptor antagonist had no effect on the convulsion. These results suggest that the convulsion caused by glufosinate ammonium is mediated through NMDA receptors.

Abstract
The efficacy of gas exchange during partial liquid ventilation (PLV) may be affected by positive end-expiratory pressure (PEEP), tidal volume (TV) and perflubron (PFOB) dose. The purpose of the present study was to clarify which factors were important for improving gas exchange during PLV. Fourteen rabbits were anesthetized and tracheostomized. Lung was introduced with intravenous oleic acid combined with saline lung lavage. After obtaining control data, PFOB 7.5 ml.kg-1 was instilled into the trachea, and ventilation settings were changed sequentially [1. TV: 10 ml.kg-1 (mTV), 2. mTV with PEEP, 3. TV: 15 ml.kg-1 (hTV), 4. hTV with PEEP]. PEEP level was set to the lower inflection point. The PFOB dose was increased to 15 ml.kg-1 and measurements were repeated under each ventilation setting. PEEP increased PaO2 in all ventilation settings. In hTV ventilation settings, incremental dose of PFOB significantly increased PaO2. The PaO2 values of all hTV ventilation settings were significantly higher than those of corresponding ventilation setting of mTV. Pulmonary compliance was significantly decreased with PEEP in hTV ventilation in addition to 15 ml.kg-1 PFOB. The results suggested that adequate gas tidal volume was the most important factor for improving gas exchange during PLV. However, PEEP or larger dose of PFOB should be avoided because they may decrease pulmonary compliance.

Abstract
The complete nucleotide sequence of the genome of a symbiotic bacterium Mesorhizobium loti strain MAFF303099 was determined. The genome of M. loti consisted of a single chromosome (7,036,071 bp) and two plasmids, designated as pMLa (351,911 bp) and pMLb (208, 315 bp). The chromosome comprises 6752 potential protein-coding genes, two sets of rRNA genes and 50 tRNA genes representing 47 tRNA species. Fifty-four percent of the potential protein genes showed sequence similarity to genes of known function, 21% to hypothetical genes, and the remaining 25% had no apparent similarity to reported genes. A 611-kb DNA segment, a highly probable candidate of a symbiotic island, was identified, and 30 genes for nitrogen fixation and 24 genes for nodulation were assigned in this region. Codon usage analysis suggested that the symbiotic island as well as the plasmids originated and were transmitted from other genetic systems. The genomes of two plasmids, pMLa and pMLb, contained 320 and 209 potential protein-coding genes, respectively, for a variety of biological functions. These include genes for the ABC-transporter system, phosphate assimilation, two-component system, DNA replication and conjugation, but only one gene for nodulation was identified.

Arabidopsis thaliana is an important model system for plant biologists. In 1996 an international collaboration (the Arabidopsis Genome Initiative) was formed to sequence the whole genome of Arabidopsis and in 1999 the sequence of the first two chromosomes was reported. The sequence of the last three chromosomes and an analysis of the whole genome are reported in this issue. Here we present the sequence of chromosome 3, organized into four sequence segments (contigs). The two largest (13.5 and 9.2 Mb) correspond to the top (long) and the bottom (short) arms of chromosome 3, and the two small contigs are located in the genetically defined centromere. This chromosome encodes 5,220 of the roughly 25,500 predicted protein-coding genes in the genome. About 20% of the predicted proteins have significant homology to proteins in eukaryotic genomes for which the complete sequence is available, pointing to important conserved cellular functions among eukaryotes.

Abstract
The genome of the model plant Arabidopsis thaliana has been sequenced by an international collaboration, The Arabidopsis Genome Initiative. Here we report the complete sequence of chromosome 5. This chromosome is 26 megabases long; it is the second largest Arabidopsis chromosome and represents 21% of the sequenced regions of the genome. The sequence of chromosomes 2 and 4 have been reported previously and that of chromosomes 1 and 3, together with an analysis of the complete genome sequence, are reported in this issue. Analysis of the sequence of chromosome 5 yields further insights into centromere structure and the sequence determinants of heterochromatin condensation. The 5,874 genes encoded on chromosome 5 reveal several new functions in plants, and the patterns of gene organization provide insights into the mechanisms and extent of genome evolution in plants.

Abstract
Anti-HPA-5b is the most commonly found platelet-specific antibody among pregnant women, but it does not cause severe fetal-neonatal alloimmune thrombocytopenia in the majority of affected infants. However, as the sequelae of the affected children may become severe, it is necessary to identify the risk factors for neonatal alloimmune thrombocytopenia. Of 21 354 consecutive pregnant women, 138 [0.65%; 95% confidence interval (CI) 0.54-0.75%], corresponding to 13.2% of the 1049 HPA-5b- women calculated by the gene frequency, were positive for anti-HPA-5b at the first trimester. Anti-HPA-5b was titrated in specimens obtained at the third trimester and antibody-positive women and their neonates were HPA-5 genotyped. Platelet counts in cord blood and 3 d after birth were assessed in the infants born to these mothers. Chi-square analysis showed no significant relationship between the titres of maternal antibody to HPA-5b and the number of pregnancies. There was a significant difference in platelet counts at d 3 between neonates who were compatible (267 x 109/l) or incompatible (220 x 109/l, P < 0.05) with maternal anti-HPA-5b. HPA-5b antibody titres >/= 64 were related to the development of thrombocytopenia (< 150 x 109/l) in neonates 1 d and 3 d after birth. A high titre (>/= 64) had a positive predictive value of 50% for thrombocytopenia 3 d after birth when the infant was HPA-5b+ and a negative predictive value of 100%. These results indicate that a high titre (>/= 64) of anti-HPA-5b is associated with a higher risk of neonatal thrombocytopenia, even if anti-HPA-5b-induced severe thrombocytopenia rarely develops.

Abstract
Cytogenetic analysis of childhood acute lymphoblastic leukemia (ALL) identified deletions of chromosome arm 11q. These observations led us to analyse the loss of heterozygosity (LOH) of chromosome arm 11q in 113 primary childhood ALL samples using 14 microsatellite markers. LOH was found in 18 (16%) patients. Detailed examination identified three distinct regions of deletion. The first region is flanked by D11S901 and D11S1391 at 11q22-23 containing the ATM gene. Mutational analysis suggested that the altered gene in this region is not the ATM gene. The second region is flanked by D11S614 and D11S924 at 11q23 containing the MLL gene. The third region is flanked by D11S1356 and D11S614 at 11q23 containing the MLL gene. All the cases with LOH at MLL locus lacked detectable MLL gene rearrangements. In addition, 20 children have been studied both at initial diagnosis and relapse; none of the individuals who relapsed acquired LOH of 11q, suggesting that 11q deletions were infrequently involved in the progression of childhood ALL. Children with 11q LOH had a good response to induction chemotherapy (P=0.015). These data suggest that alterations of putative tumor suppressor genes on 11q are important events in development of childhood ALL. Our map provides important information toward cloning putative tumor suppressor genes associated with childhood ALL.

Abstract
New non-cytotoxic taxanes synthesized from 10-deacetylbaccatin III and special hydrophobic acylating agents show remarkable MDR reversal activity (< or = 99.8%) against drug-resistant human breast cancer cells when co-administered with paclitaxel or doxorubicin. This activity is ascribed to the highly efficient blocking of P-glycoprotein efflux by these new taxanes.

Abstract
The sequence determination of the entire genome of the Synechocystis sp. strain PCC6803 was completed. The total length of the genome finally confirmed was 3,573,470 bp, including the previously reported sequence of 1,003,450 bp from map position 64% to 92% of the genome. The entire sequence was assembled from the sequences of the physical map-based contigs of cosmid clones and of lambda clones and long PCR products which were used for gap-filling. The accuracy of the sequence was guaranteed by analysis of both strands of DNA through the entire genome. The authenticity of the assembled sequence was supported by restriction analysis of long PCR products, which were directly amplified from the genomic DNA using the assembled sequence data. To predict the potential protein-coding regions, analysis of open reading frames (ORFs), analysis by the GeneMark program and similarity search to databases were performed. As a result, a total of 3,168 potential protein genes were assigned on the genome, in which 145 (4.6%) were identical to reported genes and 1,257 (39.6%) and 340 (10.8%) showed similarity to reported and hypothetical genes, respectively. The remaining 1,426 (45.0%) had no apparent similarity to any genes in databases. Among the potential protein genes assigned, 128 were related to the genes participating in photosynthetic reactions. The sum of the sequences coding for potential protein genes occupies 87% of the genome length. By adding rRNA and tRNA genes, therefore, the genome has a very compact arrangement of protein- and RNA-coding regions. A notable feature on the gene organization of the genome was that 99 ORFs, which showed similarity to transposase genes and could be classified into 6 groups, were found spread all over the genome, and at least 26 of them appeared to remain intact. The result implies that rearrangement of the genome occurred frequently during and after establishment of this species.

Abstract
Type-C virus-like particles (VLPs) were found in an Epstein-Barr (EB) virus-infected human B-cell lymphoma cell line, SP-50B, that was established from a patient with non-Hodgkin lymphoma. The cell line continuously produces a small number of type-C VLPs, 150-200 nm in diameter, over 1 year. SP-50B cells were negative for HTLV-I and HTLV-II antigens and did not contain the HTLV-I genome. In addition, two EB virus nuclear antigen (EBNA)-positive B-cell lines, SP-54-Cord and SP-57-CLL, were established from human cord blood and chronic lymphocytic leukemia (CLL), respectively, by coculture with lethally irradiated SP-50B cells. Type-C VLPs with the same morphology were also found in both cell lines.
