    The Sc/o was obtainable from this relationship between d and Rday/Vcmax, because the d values at Rday/Vcmax = 0 corresponded to α/Sc/o, where α was the photorespiratory CO2 release rate per Rubisco oxygenation rate (generally assumed to be 0.5). The calculated Sc/o values of N. tabacum and P. vulgaris exhibited good agreement with those reported by in vitro studies. The Sc/o values of both conifers were similar to those of the two angiosperm species. In contrast, the Sc/o value of G. biloba was significantly lower than those of the other four studied species. These results suggest that our new method for Sc/o estimation is applicable to C3 plants, including those for which in vitro kinetic analysis is difficult. Furthermore, results also suggest that conifer Sc/o does not differ significantly from that of C3 angiosperms, assuming α remains unchanged.BACKGROUND Adenocarcinoma in situ (AIS) and minimally invasive adenocarcinoma (MIA) are both small tumors with good prognosis after surgical resection, and most of them present as ground glass opacities (GGOs) on computed tomography (CT) screening. However, the differences in clinicopathologic features and genetic alterations between AIS and MIA are poorly elaborated, and few studies have evaluated the prognosis of MIA with different invasive components. Meanwhile, the histological features of lung lesions presenting as unchanged pure GGOs are barely understood. METHODS Clinicopathologic features and genetic alterations of AIS (n = 59) and MIA (n = 62) presenting as GGOs were analyzed. Long-term preoperative observation (ranging from 2 to 1967 days) and postoperative follow-up (ranging from 0 to 92 months) was conducted. RESULTS The tumor size and consolidation/tumor ratio were significantly larger in the MIA cohort than those in the AIS cohort both on CT and microscopy images. Immunohistochemically, the expression of p53, Ki67, and cyclin D1 was higher in MIA than in AIS. The EGFR mutation rate was significantly higher in MIA, while other genetic alterations showed no differences. Six MIA cases showed recurrence or metachronous adenocarcinoma and all the cases with a predominant micropapillary invasive pattern demonstrated this feature. GSK J4 CONCLUSIONS The current CT measurements may be helpful in distinguishing AIS from MIA, but show limited utility in predicting the histology of unchanged pure GGOs. The invasive pattern may have an influence on the postoperative process of MIA; therefore, further studies are needed to evaluate the current diagnostic criteria and treatment strategy for MIA.BACKGROUND Postoperative complications have been recognized to have an adverse prognostic impact in various types of cancer. However, in a recent study, it has been reported that postoperative complications of total gastrectomy with splenectomy have little impact on the long-term outcomes of patients with gastric cancer. In addition, the mechanisms underlying the effect of postoperative complications on outcomes remain to be elucidated. We hypothesized that immunosuppression by postoperative complications may affect long-term outcomes in patients with esophageal cancer. METHODS In this retrospective study, we assessed in 153 patients with esophageal cancer who underwent curative subtotal esophagectomy at our hospital and examined the correlation between postoperative complications, and multiple clinicopathological factors, and long-term outcomes with the patients stratified by total lymphocyte count (TLC). RESULTS The median preoperative TLC was 1432. A total of 115 patients (75.2%) had a TLC of ≥ 1000/μL (high TLC group), and the remaining 38 patients (24.8%) had a TLC of less then  1000/μL (low TLC group). Postoperative complications occurred in 39 of 153 cases (25.5%). There was no significant correlation between postoperative complications and any of the clinicopathological factors in either group. In the high TLC group, patients with postoperative complications had significantly lower overall and disease-free survival rates compared with those without complications (p  less then  0.001 and p  less then  0.01, respectively). In the low TLC group, no survival difference between patients with and without postoperative complications was observed. CONCLUSIONS Postoperative complications may have a minimal impact on long-term outcomes in immunodeficient patients.Bucket handle meniscus tears are difficult to diagnosis and are one of the most frequently missed tear patterns on magnetic resonance imaging (MR). However, this meniscal injury often requires arthroscopic intervention and preoperative characterization of the tear is important to orthopedic surgeons for treatment planning. MR is currently the best imaging modality for evaluating meniscal tears, but trauma patients in the emergency room more often undergo radiographs and further evaluation with computed tomography (CT) exams. To date, there is one study from 1988 that reported the value of CT in diagnosing bucket handle meniscus tears. We present an informative case of bucket handle meniscus tear after acute traumatic knee injury that was diagnosed on CT and later confirmed on arthroscopy.OBJECTIVE Identifying the predictive factors for tumor recurrence after partial nephrectomy (PN) is useful to determine patients who require careful observation after surgery. Therefore, we investigated recurrence after partial nephrectomy (PN) in patients with clinical T1 renal cell carcinoma (RCC) and analyzed predictive factors for recurrence-free survival (RFS). METHODS This study included 1227 patients who underwent PN for clinical T1 RCC and retrospectively investigated patients’ characteristics and tumor factors that are associated with tumor recurrence. RESULTS The median patient age was 59 years, and the median tumor size was 30 mm. Although 970 (74%) and 319 (26%) patients had clinical T1a and T1b RCCs, respectively, 20 patients (1.6%) were upstaged to pathological T3a. A positive surgical margin was found in 19 (1.5%) patients. The distribution of surgical approaches was open surgery in 428 (35%) patients and minimally invasive surgery in 799 (65%) patients. With a median follow-up of 35 months (Interquartile range 19-55 months), 39 (3.
