Abstract
Preoperative chemotherapy alone for locally advanced rectal cancer remain unclear. Neoadjuvant chemotherapy was a promising treatment for unresectable rectal cancer. Earlier preoperative systemic chemotherapy was assumed to prevent the dissemination.
Background In Japan, the significance and efficacy of preoperative chemotherapy alone for locally advanced rectal cancer remain controversial. This case report presents the apparent effectiveness of preoperative FOLFOX plus bevacizumab as shown by pathological complete response (pCR). Additionally, we review the relevant literature and discuss the clinical management of locally advanced rectal cancer with preoperative chemotherapy. Case presentation A 59-year-old male presented with severe constipation, bloody stool and a loss of 10% of his body weight over 3 months. Preoperative examination revealed locally advanced rectal cancer with extensive invasion of the bladder wall and enlarged regional lymph nodes. Thus, this lesion was assigned a preoperative classification of T4bN2bM0 stage IIIC according to the 8th Union for International Cancer Control (UICC) guidelines. Therefore, the patient initially underwent an external loop colostomy of the transverse colon. Next, the patient received chemotherapy including FOLFOX plus bevacizumab. After 12 cycles of chemotherapy, the tumor size was markedly decreased, and all lymph node metastases had disappeared. Therefore, the patient underwent conventional resection of the rectum with D3 lymph node dissection and closure of the colostomy. Histopathological analysis of the resected specimen revealed that all lesions were fibrotic and devoid of any viable cancer cells. Thus, this lesion was assigned a final classification of ypT0N0M0 stage 0. Conclusions We present the rare case of a patient with surgically resected locally advanced rectal cancer who demonstrated an impressive pCR with preoperative chemotherapy, which included FOLFOX plus bevacizumab.

Abstract
AIM To evaluate the diagnostic feasibility of probabilistic analysis using voxel-based morphometry (VBM) in differentiating primary central nervous system lymphoma (PCNSL) from glioblastoma (GBM). MATERIALS AND METHODS In total, 118 patients with GBM (57 males, 61 females; mean [± standard deviation] age, 56.9±19.3 years; median, 61 years) and 52 patients with PCNSL (37 males, 15 females; mean age, 62±13.3 years, median, 66 years) were studied retrospectively. Each patient underwent preoperative contrast-enhanced T1-weighted imaging (CE-T1WI) using a 1.5 or 3 T magnetic resonance imaging (MRI) system. To assess preferential occurrence sites, images from CE-T1WI were co-registered and spatially normalised using the MNI152 T1 template. Subsequently, a region of interest (ROI) was placed in the centre of the enhancing tumour in normalised images with 1-mm isotropic resolution. The same ROI between normalised and T1 template images was set up using an ROI manager function in ImageJ software. A spherical volume of interest (VOI) with a radius of 10 mm was determined. A probability map was created by overlaying each image with the VOI. Each VOI was removed from T1 template images for VBM analysis. VBM analysis was performed using statistical parametric mapping (SPM) 12 software under default settings. RESULTS VBM analysis showed significantly higher frequency in the splenium of the corpus callosum among PCNSL patients than among GBM patients (p<0.05; family-wise error correction). CONCLUSION Topographic analysis using VBM provides useful information for differentiating PCNSL from GBM.

Abstract
AIM To clarify the factors related to outcomes of individuals missing through dementia wandering. METHODS We carried out binary logistic regression analysis with 160 family members of missing persons (88 survivors, 72 decedents). RESULTS Living alone at the point of going missing (OR 13.45, 95% CI 1.12-161.56), being found within the local area (OR 6.36, 95% CI 2.26-17.88), and a long period between going missing and being found (OR 6.14, 95% CI 3.14-12.00) were significantly related with death. CONCLUSIONS Early detection of missing persons is essential in preventing dementia wandering-related deaths. The time taken to locate missing dementia patients who lived alone was longer, relative to that of those who lived with others, and this increased the risk of death. Furthermore, the locations where the deceased were located tended to be local, rather than distant areas. Geriatr Gerontol Int 2019; 19: 902-906.

Abstract
BACKGROUND AND PURPOSE Intravoxel incoherent motion imaging, which simultaneously measures diffusion and perfusion parameters, is promising for brain tumor grading. However, intravoxel incoherent motion imaging has not been tested in children. The purpose of this study was to evaluate the correlation between intravoxel incoherent motion parameters and histology to assess the accuracy of intravoxel incoherent motion imaging for pediatric intracranial tumor grading. MATERIALS AND METHODS Between April 2013 and September 2015, 17 children (11 boys, 6 girls; 2 months to 15 years of age) with intracranial tumors were included in this retrospective study. Intravoxel incoherent motion parameters were fitted using 13 b-values for a biexponential model. The perfusion-free diffusion coefficient, pseudodiffusion coefficient, and perfusion fraction were measured in high- and low-grade tumors. These intravoxel incoherent motion parameters and the ADC were compared using the unpaired t test. The correlations between the intravoxel incoherent motion parameters and microvessel density or the MIB-1 index were analyzed using the Spearman correlation test. Receiver operating characteristic analysis was used to evaluate diagnostic performance. RESULTS The perfusion-free diffusion coefficient and ADC were lower in high-grade than in low-grade tumors (perfusion-free diffusion coefficient, 0.85 ± 0.40 versus 1.53 ± 0.21 × 10-3 mm2/s, P < .001; ADC, 1.04 ± 0.33 versus 1.60 ± 0.21 × 10-3 mm2/s, P < .001). The pseudodiffusion coefficient showed no difference between the groups. The perfusion fraction was higher in high-grade than in low-grade tumors (21.7 ± 8.2% versus 7.6 ± 4.3%, P < .001). Receiver operating characteristic analysis found that the combined perfusion-free diffusion coefficient and perfusion fraction had the best diagnostic performance for tumor differentiation (area under the curve = 0.986). CONCLUSIONS Intravoxel incoherent motion imaging reflects tumor histology and may be a helpful, noninvasive method for pediatric intracranial tumor grading.

Abstract
Previous studies reported the activation of the apoptotic cascade by vitrification in mature porcine oocytes (Vallorani et al. 2012 Anim. Reprod. Sci. 135, 68-74) and that the cathepsin B inhibitor E-64 improved developmental competence of bovine oocytes via an antiapoptotic effect (Balboula et al. 2013 Reproduction 146, 407-417). The present study was carried out to test whether E-64 affected the developmental competency of porcine oocytes vitrified at the germinal vesicle stage. Cumulus-enclosed porcine oocytes were vitrified in microdrops and warmed by our method (Somfai et al. 2015 J. Reprod. Dev. 61, 571-579). Then, the oocytes were subjected to in vitro maturation (IVM) for 46h in a chemically defined porcine oocyte medium supplemented with 10ng mL−1 of epidermal growth factor, 10IU mL−1 of eCG, and 10IU mL−1 of hCG and during the first 22h of IVM with 1mM dibutyryl cyclic adenosine monophosphate. Then, cumulus-oocyte complexes were fertilized in vitro and presumptive zygotes were cultured in 50-µL drops of porcine zygote medium-3 for 7 days in 6-well dishes covered by paraffin oil in an atmosphere of 5% CO2, 5% O2, and 90% N2 at 39°C. On Day 5 (Day 0=IVF), the porcine zygote medium-3 was supplemented with 10% (vol/vol) FCS. The effects of 1.0μM of E-64 supplementation during IVM of non-vitrified and vitrified cumulus-oocyte complexes were investigated in a 2×2 factorial design. Survival rates after IVM, cleavage rates on Day 2, blastocyst rates, and total cell numbers in blastocysts on Day 7 were compared among groups. The experiment was replicated 5 times. Results were analysed by ANOVA and Tukey’s multiple comparison test. The percentages of live oocytes were statistically similar when oocytes were matured in the absence or presence of E-64 both in non-vitrified (99.2% v. 99.6%, respectively) and vitrified (94.3% v. 90.8%, respectively) groups. Similarly, IVM without or with E-64 supplementation had no effect on subsequent cleavage and blastocyst development rates in non-vitrified (67.4% v. 71.2% and 38.7% v. 43.2%, respectively) and vitrified (46.8% v. 48.8% and 14.6% v. 22.8%, respectively) oocytes. Irrespective of E-64 treatment, all survival and developmental rates in the vitrified groups were significantly lower (P<0.05) compared with those of their non-vitrified counterparts except for the blastocyst development rate in the E-64-treated vitrified group, which did not differ significantly from those of the non-vitrified groups with or without E-64 treatment. There was no statistical difference in mean blastocyst cell numbers among the groups, ranging between 86.5±15.8 and 118±10.6. In conclusion, E-64 treatment had no effect on embryo production rates, which suggests that in our system, cathepsin-mediated apoptosis during IVM might not be the factor to limit embryo production using either fresh oocytes or those vitrified at the immature stage.

Abstract
RATIONALE Gastric adenocarcinoma of fundic gland type (GA-FG) is a new histological type of gastric cancer manifesting with differentiation into a fundic gland. Furthermore, gastric adenocarcinoma of fundic gland mucosa type (GA-FGM) is a tumor that shows differentiation into not only a fundic gland but also foveolar epithelium and a mucous gland. These tumors tend to invade the submucosal layer. However, no cases of these tumors being localized only in the submucosa have been reported. Here, we present a case of GA-FGM localized in the submucosa and describe the cytological features of this tumor. To our knowledge, this is the first reported case of GA-FGM localized in the submucosa. PATIENT CONCERNS A man in his early 70s was referred to our institution because of the detection of a gastric submucosal tumor during a health checkup. DIAGNOSES Gastric adenocarcinoma of fundic gland mucosa type. INTERVENTIONS Endoscopic ultrasound-guided fine-needle aspiration (FNA), endoscopic submucosal dissection (ESD), and total gastrectomy with lymph node dissection were performed. OUTCOMES The FNA specimen showed epithelial cells with low-grade atypia. In the ESD specimen, adenocarcinoma showing a gastric fundic gland mucosa-like morphology was observed. Immunohistochemical analysis showed positive staining for pepsinogen I, H+/K+-adenosine triphosphatase, MUC6, and MUC5AC and negative staining for MUC2 and CD10, indicating tumor differentiation into fundic gland mucosa. Therefore, the tumor was diagnosed as GA-FGM, with localization in the submucosal layer. Total gastrectomy and lymph node dissection were performed because of the positive margins of the ESD specimen. Neither residual tumor nor lymph node metastasis was detected; however, many foci of heterotopic gastric glands (HGGs) were observed in the gastric wall, suggesting that GA-FGM arose from an HGG. After treatment, no recurrence was observed during a 1-year follow-up period. LESSONS Various tumors may arise from HGGs. Furthermore, when an FNA specimen shows gastric fundic gland mucosa-like epithelial cells with weak atypia, the possibility of GA-FG and GA-FGM should be considered.

Abstract
BACKGROUND AND PURPOSE Glycosaminoglycan chemical exchange saturation transfer (gagCEST) imaging allows the direct measurement and mapping of glycosaminoglycans. In this study, we aimed to evaluate the usefulness of gagCEST imaging in the quantitative assessment of intervertebral disc degeneration in a comparison with Pfirrmann grade and T1-ρ measurements. MATERIALS AND METHODS Ninety-six lumbar intervertebral discs in 24 volunteers (36.0 ± 8.5 years of age, 21 men and 3 women) were examined with both gagCEST imaging and T1-ρ measurements. The gagCEST imaging was performed at 3T with a saturation pulse with 1.0-second duration and the B1 amplitude of 0.8 μT followed by imaging by a 2D fast spin-echo sequence. The Z-spectra were obtained at 25 frequency offsets from -3 to +3 ppm (step, 0.25 ppm). A point-by-point B0 correction was performed with a B0 map. The gagCEST signal and T1-ρ values were measured in the nucleus pulposus in each intervertebral disc. The Pfirrmann grades were assessed on T2-weighted images. RESULTS The gagCEST signal at grade I (5.36% ± 2.79%) was significantly higher than those at Pfirrmann grade II (3.15% ± 1.40%, P = .0006), grade III (0.14% ± 1.03%, P < .0001), grade IV (-1.75% ± 2.82%, P < .0001), and grade V (-1.47% ± 0.36%, P < .0001). The gagCEST signal at grade II was significantly higher than those of grade III (P < .0001), grade IV (P < .0001), and grade V (P < .0001). The gagCEST signal was significantly correlated negatively with Pfirrmann grade (P < .0001) and positively correlated with T1-ρ (P < .0001). CONCLUSIONS GagCEST imaging could be a reliable and quantitative technique for assessing intervertebral disc degeneration.

Abstract
Background: Collision tumors, composed of histologically distinct tumor types, are rare entities, especially in the colorectum, and corresponding evidence-based clinical management or treatment strategies are poorly defined. This is the first report of a collision tumor composed of two histologically distinct adenocarcinomas. Case presentation: A 78-year-old male showed severe anemia and a 10% body weight loss over 1 month. Preoperative examination revealed T3N1M0 stage IIIA gastric cancer and T3N0M0 stage IIA rectal cancer. Distal gastrectomy and rectectomy with regional lymph node dissection were performed. Immunohistochemistry revealed two distinct adenocarcinomas with gland duct structures – a colorectal adenocarcinoma and a disseminated gastric adenocarcinoma – that had collided to form an invasive tumor on the serosal surface of the anterior rectum wall. Conclusion: This extremely rare case of a collision tumor supports that precise immunohistochemical identification of all tumor components is needed for guiding decisions affecting overall prognosis, adjuvant treatment and survival.

Abstract
This paper reports a multi-throughput multi-organ-on-a-chip system formed on a pneumatic pressure-driven medium circulation platform with a microplate-sized format as a novel type of microphysiological system. The pneumatic pressure-driven platform enabled parallelized multi-organ experiments (i.e. simultaneous operation of multiple multi-organ culture units) and pipette-friendly liquid handling for various conventional cell culture experiments, including cell seeding, medium change, live/dead staining, cell growth analysis, gene expression analysis of collected cells, and liquid chromatography-mass spectrometry analysis of chemical compounds in the culture medium. An eight-throughput two-organ system and a four-throughput four-organ system were constructed on a common platform, with different microfluidic plates. The two-organ system, composed of liver and cancer models, was used to demonstrate the effect of an anticancer prodrug, capecitabine (CAP), whose metabolite 5-fluorouracil (5-FU) after metabolism by HepaRG hepatic cells inhibited the proliferation of HCT-116 cancer cells. The four-organ system, composed of intestine, liver, cancer, and connective tissue models, was used to demonstrate evaluation of the effects of 5-FU and two prodrugs of 5-FU (CAP and tegafur) on multiple organ models, including cancer and connective tissue.
