Abstract
OBJECTIVE Chondrocyte differentiation is crucial for long bone growth. Many cartilage extracellular matrix (ECM) proteins reportedly contribute to chondrocyte differentiation, indicating that mechanisms underlying chondrocyte differentiation are likely more complex than previously appreciated. Angiopoietin-like protein 2 (ANGPTL2) is a secreted factor normally abundantly produced in mesenchymal lineage cells such as adipocytes and fibroblasts, but its loss contributes to the pathogenesis of lifestyle- or aging-related diseases. However, the function of ANGPTL2 in chondrocytes, which are also differentiated from mesenchymal stem cells, remains unclear. Here, we investigate whether ANGPTL2 is expressed in or functions in chondrocytes. METHODS First, we evaluated Angptl2 expression during chondrocyte differentiation using chondrogenic ATDC5 cells and wild-type epiphyseal cartilage of newborn mice. We next assessed ANGPTL2 function in chondrogenic differentiation and associated signaling using Angptl2 knockdown ATDC5 cells and Angptl2 knockout mice. RESULTS ANGPTL2 is expressed in chondrocytes, particularly those located in resting and proliferative zones, and accumulates in ECM surrounding chondrocytes. Interestingly, long bone growth was retarded in Angptl2 knockout mice from neonatal to adult stages via attenuation of chondrocyte differentiation. Both in vivo and in vitro experiments show that changes in ANGPTL2 expression can also alter p38 mitogen-activated protein kinase (MAPK) activity mediated by integrin α5β1. CONCLUSION ANGPTL2 contributes to chondrocyte differentiation and subsequent endochondral ossification through α5β1 integrin and p38 MAPK signaling during bone growth. Our findings provide insight into molecular mechanisms governing communication between chondrocytes and surrounding ECM components in bone growth activities.

Abstract
We developed a fast X-ray detector system for nuclear resonant scattering (NRS) experiments. Our system employs silicon avalanche photo-diode (Si-APD) as a fast X-ray sensor. The system is able to acquire both timing and energy of a single X-ray photon simultaneously in a high rate condition, 106 counts per second for one Si-APD. The performance of the system was investigated in SPring-8, a synchrotron radiation facility in Japan. Good time resolution of 120 ps (FWHM) was achieved with a slight tail distribution in the time spectrum by a level of 10-9 at 1 ns apart from the peak. Using this system, we successfully observed the NRS from the 26.27-keV level of mercury-201, which has a half-life of 630(50) ps. We also demonstrated the reduction of background events caused by radioactive decays in a radioactive sample by discriminating photon energy.

Abstract
We propose a new classification for esophagogastric junction (EGJ) incorporating both physiologic and morphologic characteristics. Additionally, we contrast it with the Chicago v 3.0 EGJ classification. With Institutional Review Board (IRB) approval, prospectively maintained database was queried to identify patients who underwent high-resolution manometry (HRM) and pH-study between October 2011 and October 2015. Patients with prior foregut intervention, pH study on acid suppression, esophageal dysmotility, or lower esophageal sphincter-crural diaphragm separation of >5 cm were excluded. We classified patients into three groups-Type-A: Complete overlap of lower esophageal sphincter-crural diaphragm (single high-pressure zone); Type-B: Double high-pressure zone with pressure inversion point (PIP) at or above lower esophageal sphincter; Type-C: Double high-pressure zone with PIP below lower esophageal sphincter. A total of 214 included patients were divided into Type-A (n = 101), Type-B (n = 32), and Type-C (n = 81). Abdominal lower esophageal sphincter length (AL), lower esophageal sphincter pressure (LESP), and lower esophageal sphincter pressure integral (LESPI) were significantly lower in Type-C than both Type-A and Type-B [AL(cm): 0.2 vs. 2(P < 0.001) vs. 1.6(P <0.001); LESP(mmHg): 20.1 vs. 32.1(P < 0.001) vs. 29.2(P < 0.001); LESPI(mmHg.cm.s): 187 vs. 412(P < 0.001) vs. 343(P < 0.05)] while overall lower esophageal sphincter length(OL) and Integrated Relaxation Pressure (IRP) were significantly lower in Type-C than Type-A [OL(cm): 2.9 vs. 3.6(P < 0.001); IRP(mmHg): 8.2 vs. 9.6(P < 0.05)]. Type-C patients had significantly higher positive pH score (>14.7) than Type-A and Type-B [72% vs. 47% (P < 0.05) vs. 41% (P < 0.001)]. In Type-C morphology, there is both anatomical and physiological deterioration, weakest lower esophageal sphincter function (abdominal length, lower esophageal sphincter pressure, and lower esophageal sphincter pressure integral) and is most likely to be associated with pathological reflux. This proposed classification incorporates both physiological and morphological derangements in a graded fashion.

Abstract
In this study, sperms collected from the right and left cauda epididymis were grouped into having canine prostatic fluid (PF) sensitization or not diluted with egg yolk Tris-fructose citrate extender, and stored at 4°C. The necessity of canine PF in cooled preservation was determined by elucidating the sperm quality after the storage. As a result, while there was no difference among all groups up to 48 hr of storage, after storage for 96 hr and more, a significantly lower sperm motility was observed in the group without being sensitized to PF than the groups with being sensitized to PF (p < .05, p < .01). Although sperm abnormality increased in all groups with increased storage time, the group without being sensitized to PF showed significantly higher sperm abnormality than did the groups with being sensitized to PF after storage for 24 hr and more (p < .01). From these findings, we concluded that PF was necessary for the cooled preservation of the canine sperm because these sperms were protected from any effects of low temperatures by being sensitized to PF.
