＜正＞Alternate bearing in pistachio （Pistacia vera L., cv. Kerman） is due to the excessive abscission of the floral buds for the next year’s crop during the heavy on-year. Abscission of floral buds begins at nut fill （j.ne） and proceeds through j.ly. The floral buds are considered poor competitors in relation to the developing nuts. Whereas this mechanism was known, the physiological basis for floral bud abscission was not *** from our basic research documented that the concentrations of two important cytokinins, zeatin riboside and isopentyladenosine, each decreased 40% in floral buds on shoots carrying an on-year crop [greater than 70 nuts （fruit） per branch].The decrease in

Labyrinth weirs provide higher discharge capacity than conventional weirs, with the ability to pass large flows at comparatively low heads. Labyrinth weirs are primarily used as spillways for dams where the spillway width is restricted. In recent years, many research investigations have considered the hydraulic performance of labyrinth weirs, particularly as dependent on the geometric features. The previous work has improved the design basis for such weirs. However, their design still requires experimentally derived and generalized performance curves. It is especially important to observe the behavior of the weir nappe to ensure the design provides hydraulic optimization and to account for pressure fluctuations, possible vibrations, resonance effect, noise and flow surging. In the present study, discharge coefficients were experimentally determined for both circular labyrinth weirs and sharp crested trapezoidal labyrinth weirs of varying side wall angle (α). Additional studies were completed with nappe breakers included to reduce the impact of vibration on the labyrinth weirs. In general, the test data indicated that nappe breakers placed on the trapezoidal labyrinth weirs and circular labyrinth weirs reduced the discharge coefficient by up to 4% of the un-amended weir.

Chronic obstructive pulmonary disease is an inflammatory condition with increased risk of lung cancer. We hypothesized that curcumin/ bioperine (CB), which has anti-inflammatory effects, may reduce cytological abnormalities in the sputum of patients with COPD. We conducted a 3-month, three-to-one randomized, doubleblind, pilot trial of escalating doses of CB in patients with moderate or worse COPD who were capable of producing sputum. The primary efficacy endpoint was changed in sputum cytology. We also explored changes in fluorescence in situ hybridization (FISH). We obtained sputum samples for cytology and chromosome abnormalities at baseline and each monthly follow-up visit. We enrolled 57 participants, with 35 completing the study. The participants’ mean age (standard deviation [SD]) was 66.6 (8.2) years, and they were mainly male (91.2%), with an average of 63.8 pack-years of smoking history. Also, 42.1% of participants were active smokers and the mean (SD) FEV1 was 37% (13%). At baseline, 13 subj.cts had moderate or worse dysplasia (22.8%). Subj.cts with moderate to severe sputum dysplasia had more chromosome abnormalities in epithelial cells and neutrophils, as measured by deletion and aneuploidy in 10q22.3. The changes in sputum cytology and chromosome abnormalities did not differ between the active and placebo arms. CB was well tolerated at the bid doses of 1, 1.5, and 2 gm of curcumin and 5 mg of bioperine, with minor side effects related to the gastrointestinal tract. In this short pilot trial, CB compared to placebo did not alter cytological and chromosomal abnormalities seen in sputum of patients with COPD.

背景与目的少女乳房肥大症表现为单侧或双侧乳房快速增大，常见于青春期，是一种在医学文献中鲜见报道的罕见疾病。目前，尚无基于患者或疾病的用于解决这一问题的循证医学治疗方针。本研究通过Meta分析对已报道的病例报告进行分析，并得出诊断、治疗这一不常见问题的累积算法。方法使用多个关键词通过PubMed数据库进行文献搜索，提取出每一个病例报道中的相关信息，包括：患者年龄、初潮情况、组织切除量、手术方法、手术次数、药物治疗和恢复情况等，使用SPSS15．1统计学软件进行数据分析。结果将乳房切除和乳房缩小两种术式的复发概率进行比较，结果有显著统计学意义（P〈0．01），优势比为7．0。结论本文提供的证据证明某些用于治疗少女乳房肥大症的方法更加有效。他莫西芬（Tamoxifen，一种抗雌激素药）药物治疗是源自于以往文献的疗法，无治疗禁忌证。皮下乳房切除术是将全部乳腺组织完整切除，其复发可能性最小，但术后畸形严重。乳房缩小术可以显著改善乳房的术后外观，但务必告知患者术后复发的概率将有所增加，术后进行他莫西芬药物治疗可降低复发概率。

Several long-term studies have provided strong support demonstrating that growing crops under elevated[CO_(2)]can increase photosynthesis and result in an increase in yield,flavour and nutritional content(including but not limited to Vitamins C,E and pro-vitamin A).In the case of tomato,increases in yield by as much as 80%are observed when plants are cultivated at 1000 ppm[CO_(2)],which is consistent with current commercial greenhouse productionmethods in the tomato fruit *** results provide a clear demonstration of the potential for elevating[CO_(2)]for improving yield and quality in greenhouse *** maj.r focus of this review is to bring together 50 years of observations evaluating the impact of elevated[CO_(2)]on fruit yield and fruit nutritional *** the final section,we consider the need to engineer improvements to photosynthesis and nitrogen assimilation to allow plants to take greater advantage of elevated CO_(2) growth conditions.

Multiple reference optical coherence tomography（MR-OCT） is a recently developed, low-cost and compact time-domain OCT solution for primary care and consumer level applications. A combination of a voice coil actuator and a partial mirror（PM） extends the scan range for imaging depths of approximately 1 mm in biological samples. Our previous research on MR-OCT is based only on intensity information obtained from the depth-resolved interference signal. In this Letter, we extract the phase information from the MR-OCT signal and, hence, provide an additional contrast modality. The phase sensitivity of the system is measured to be approximately 0.2 and 1.5 rad for the first and twelfth orders of reflection when using a mirror as the *** Letter describes first results of phase-sensitive data measured on a phantom obtained with MR-OCT. Data from a chick embryo chorioallantoic membrane（CAM） is used to demonstrate the feasibility of MR-OCT for in vivo phase-sensitive imaging.
