Abstract	We report a 27 years-old previously healthy male admitted to a psychiatric hospital because of abnormal behavior. He was suspected meningoencephalitis with fever, abnormal sweating, muscle tone, confusion, and introduced to the neurology department of our hospital. After admission, increasing convulsions and apnea attack required mechanical ventilation therapy. Anti-N-methyl-D-aspartate( NMDA) - receptor encephalitis was diagnosed based on positive (20-fold) anti-NMDA antibody in cerebrospinal fluid examination. An enhanced chest computed tomography (CT) showed a 43 mm cystic mass with calcification of the anterior mediastinum. He underwent the tumor resection under median sternotomy on the 18th hospital day. The plasmapheresis and steroid therapies were treated after the operation. The consciousness level gradually improved, the patient was withdrawn from the respirator on the post operative day( POD) 35, and transferred to a rehabilitation hospital on POD 60. The pathological result was mature teratoma. However, no specific findings such as inflammatory cell infiltration into nerve components were observed. Anti-NMDA receptor encephalitis was established by Dalmau in 2007 as encephalitis associated with ovarian teratoma. It presents mainly in young adult women with psychiatric symptoms, and requires mechanical ventilation management due to disturbance of consciousness, convulsions, and central hypoventilation in a short period of time. It presents severe symptoms in the acute phase and shows a unique clinical finding with a good prognosis even though it shows a protracted course. Treatment requires prompt tumor detection and early resection, as well as methylprednisolone (mPSL) pulse, plasmapheresis, and high-dose gamma globulin therapy. It is a neurological disease that requires emergency response, and the understanding and prompt response of related departments is important.

Abstract	Objectives: Continuous subcutaneous injection (CSCI) followed by a once-daily transdermal patch is a reasonable strategy for rapid titration of fentanyl in patients with cancer pain who are unable to take oral medication or have renal impairment, but the effectiveness and safety have not been demonstrated. Methods: Medical records of patients with moderate to severe cancer pain who underwent titration of fentanyl by CSCI between October 2019 and October 2021 at Kitano Hospital, Osaka, Japan, were retrospectively reviewed. The dose of fentanyl was increased to a maximum of 0.05 mg/hour. If the dose was inadequate, the fentanyl patch was added on CSCI. When pain relief was adequate, CSCI was completely converted to the patch. Results: Thirty-three patients were enrolled. Titration was completed successfully in 28 patients (85%) over a median of 2 days. The average Numeric Rating Scale for pain decreased by at least 66% in 22 patients (67%) and by at least 33% in 7 (21%). After conversion to the patch, two patients (6.1%) required to increase the dose of fentanyl within a week. Two patients (6.1%) experienced moderate drowsiness during titration. Conclusions: Fentanyl titration by CSCI is an effective and safe method for achieving rapid pain control.

Abstract	A pulmonary artery aneurysm (PAA) is a rare condition. It is treated in various ways, depending on its location and size. Herein, we describe the preoperative diagnosis of a PAA that was resected by segmentectomy. A 44-year-old female underwent CT, which revealed a 15-mm saccular protrusion in the right pulmonary artery and was diagnosed with PAA. The patient was initially observed without requiring further treatment, but a gradual increase in size led to therapeutic intervention. Because the PAA was located just peripheral to the right A8 bifurcation, embolization using interventional radiology was deemed too difficult. Therefore, a surgical intervention was planned. Subsequently, S8 segmentectomy, basal segmentectomy, and basilar pulmonary artery ligation were all considered. Ultimately, basal segmentectomy was selected because it allowed the resection of the pulmonary artery and did not result in invalid ventilation of the basal segment. A basal segmentectomy was performed, and the PAA was safely removed without hemorrhage. Histopathological examination revealed arterial and venous wall-like areas, and the patient was diagnosed with pulmonary artery malformation. A PAA is typically treated with coil embolization, ligation of the pulmonary artery, aneurysmectomy, and lung resection; however, no clear treatment guidelines exist. After discussion, we selected basal segmentectomy as a safe and minimally invasive procedure, and we resected the PAA without complications. The optimal treatment strategy for PAAs varies according to location and size, and a careful treatment plan should be established.

Abstract	This study aimed to determine the characteristics of childrearing environments related to social development in early childhood. A questionnaire survey was conducted with the caregivers of children attending an urban preschool to identify the characteristics of the childrearing environment in relation to social development in early childhood. The TK Infant Development Test was used to assess social development. The Index of Child Care Environment (13 items in four domains) was used to assess the childrearing environment. Six of the items were used to assess parent-child interaction at home. The correlation coefficients between the social development and childrearing environment items were calculated. Multiple regression analysis was conducted with social development (DQ) as the dependent variable and the childcare environment items as the independent variables. Two types of analyses were conducted: forced entry (model 1) and stepwise (model 2). The results of our univariate and multivariate analyses showed a significant association between the social development items and childrearing environment items after adjusting for the target attributes. This finding suggests that an appropriate childrearing environment promotes social development in early childhood.

Abstract	In industrial applications such as fermentation and heterologous protein production, various Aspergillus oryzae and A. sojae strains are used. Although genetic engineering techniques have been developed for these filamentous fungi, applying such classical techniques to many strains is difficult. Therefore, the establishment of innovative technologies applicable to various industrial strains is required. We previously developed a genome editing technology using the CRISPR/Cas9 system for the efficient genetic engineering of A. oryzae; however, this system is limited by its protospacer adjacent motif sequence. In A. sojae, no genetic engineering using genome editing has been developed. In this study, we aimed to develop a genome editing technology using the Cpf1 nuclease for the genetic engineering of A. oryzae and A. sojae. AMA1-based genome editing vectors bearing codon-optimized cpf1 expression cassettes were constructed, and guide RNA expression cassettes were inserted into the Cpf1 genome editing vectors. Using the resultant plasmids, we performed mutagenesis of the AowA and sC genes in A. oryzae and the AswA gene in A. sojae. We deleted these genes by co-introducing the Cpf1 genome editing plasmid and the donor plasmid. Our study demonstrates that the CRISPR/Cpf1 system can be used as an efficient alternative to the CRISPR/Cas9 system to genetically engineer A. oryzae and as a new approach for efficient genetic engineering of A. sojae.

Abstract	We recently reported that fermentable nondigestible carbohydrates such as oligosaccharides, commonly increase colonic alkaline phosphatase (ALP) activity and the gene expression of Alpi-1, coding for rat intestinal alkaline phosphatase-I isozyme in rats and that the effect of oligosaccharides on colonic ALP activity is affected by the quality of dietary fats. We hypothesized that the amount of dietary fat would modulate the effect of oligosaccharides on colonic ALP and luminal environment in rats. In experiment 1, male Sprague-Dawley rats were fed a low-fat (LF, 5% lard) or high-fat (HF, 30% lard) diet with or without 4% fructo-oligosaccharides (FOS). In experiment 2, they were fed a 2.5%, 7%, 20%, or 40% fat (lard) diet with 4% FOS for 2 weeks. Dietary FOS in the HF diet (HF-FOS) significantly increased ALP activity in the colon and cecal digesta and colonic expression of Alpi-1, but not in the LF diet with FOS groups (LF-FOS). In comparison to the LF-FOS group, the increases in fecal mucins, Lactobacillus ratio, as well as cecal n-butyrate, and the decrease in fecal Clostridium coccoides, were more pronounced in the HF-FOS group. Compared with the 2.5% or 7% fat + FOS diet, the 20% fat + FOS diet significantly increased colonic ALP activity, Alpi-1 expression, and fecal mucins. These factors did not differ significantly between 20% and 40% fat + FOS diets. To exert the maximum effect of FOS on the colonic luminal environment, including ALP activity in rats, significantly more fat may be required than that contained present a LF diet.

Abstract	L-DOPA is an amino acid that is used as a treatment for Parkinson's disease. A simple enzymatic synthesis method of L-DOPA had been developed using bacterial L-tyrosine phenol-lyase (Tpl). This review describes research on screening of bacterial strains, culture conditions, properties of the enzyme, reaction mechanism of the enzyme, and the reaction conditions for the production of L-DOPA. Furthermore, molecular bleeding of constitutively Tpl-overproducing strains is described, which were developed based on mutations in a DNA binding protein, TyrR, which controls the induction of tpl gene expression.
