Increased nighttime respiratory losses decrease the amount of photoassimilates available for plant growth and yield. We hypothesized that the increased respiratory carbon loss under high night temperatures(HNT) could be compensated for by increased photosynthesis during the day following HNT exposure. Two rice genotypes, vandana(HNT-sensitive) and Nagina 22(HNT-tolerant), were exposed to HNT(4 ℃ above the control) from flowering to physiological maturity. They were assessed for alterations in the carbon balance of the source(flag leaf) and its subsequent impact on grain filling dynamics and the quality of spatially differentiated sinks(superior and inferior spikelets). Both genotypes exhibited significantly higher night respiration rates. However, only Nagina 22 compensated for the high respiration rates with an increased photosynthetic rate, resulting in a steady production of total dry matter under HNT. Nagina 22 also recorded a higher grain-filling rate, particularly at 5 and 10 d after flowering, with 1.5- and 4.0-fold increases in the translocation of ^(14)C sugars to the superior and inferior spikelets, respectively. The ratio of photosynthetic rate to respiratory rate on a leaf area basis was negatively correlated with spikelet sterility, resulting in a higher filled spikelet number and grain weight per plant, particularly for inferior grains in Nagina 22. Grain quality parameters such as head rice recovery, high-density grains, and gelatinization temperature were maintained in Nagina 22. An increase in the rheological properties of rice flour starch in Nagina 22 under HNT indicated the stability of starch and its ability to reorganize during the cooling process of product formation. Thus, our study showed that sink adjustments between superior and inferior spikelets favored the growth of inferior spikelets, which helped to offset the reduction in grain weight under HNT in the tolerant genotype Nagina 22.

Introduction: Endoscopy is commonly performed to evaluate for suspected or established esophageal diseases including gastroesophageal reflux disease (GERD) and its complications. The newly developed PillCam ESO Esophageal Capsule offers an alternative approach to visualize the esophagus and to evaluate patients with suspected esophageal disease. Aim: Compare the accuracy (specifi-city, sensitivity, positive predictive value [PPv], and negative predictive value [NPv]) of esophageal capsule endoscopy (ECE) compared with esophagogastroduodenoscopy (EGD) in evaluating patients with GERD. Methods: A multicenter pivotal trial was conducted at seven sites. The PillCam ESO esophageal capsule is similar to the standard capsule endoscope used for the small bowel but acquires video images from both ends of the device at 2 frames/second/end. A total of 106 patients (93 GERD; 13 Barrett) underwent ECE followed by EGD. ECE videos were evaluated by an investigator blinded to EGD findings. A blinded adjudication committee reviewed all discrepant findings between ECE and EGD. Results: Sixty-six of 106 patients had positive esophageal findings, ECE identified esophageal abnormalities in 61 (sensitivity, 92% ; specificity, 95% ). The per-protocol sensitivity, specificity, PPv, and NPv of ECE for Barrett esophagus were 97% , 99% , 97% , and 99% , respectively, and for esophagitis 89% , 99% , 97% , and 94% , respectively. ECE was preferred over EGD by all patients. There were no adverse events related to ECE. Conclusions: ECE is a convenient and sensitive method for visualization of esophageal mucosal pathology and may provide an effective method to evaluate patients for esophageal disease.

Objectives: To review randomised controlled trials of treat- ment with a proton pump inhibitor in patients with ulcer bleeding and to deter mine the impact on mortality,rebleedi- ng, and surgical intervention. Design: Systematic review and meta-analysis. D ata sources: Cochrane Collaboration’s trials register, Medline, and Embase,hand searched abstracts, and pharmaceutical *** methods: Included random ised controlled trials that compared proton pump inhibitor with placebo or H2 re ceptor antagonist in endoscopically proved bleeding ulcer and reported at least one of mortality, rebleeding, or surgical intervention. Trials were graded for m ethodological quality. Two assessors independently reviewed each trial, and disa greements were resolved by ***:We included 21 randomised controll ed trials comprising 2915 patients. Proton pump inhibitor treatment had no signi ficant effect on mortality (odds ratio 1.11, 95%confidence interval 0.79 to 1.5 7; number needed to treat(NNT) incalculable) but reduced rebleeding (0.46, 0.33 to 0.64; NNT 12) and surgery (0.59,0.46 to 0.76; NNT 20). Results were similar w hen the meta-analysis was restricted to the 10 trials with the highest methodol ogical quality: 0.96, 0.46 to 2.01, for mortality; 0.41, 0.25 to 0.68, NNT 10, f or rebleeding; 0.62, 0.46 to 0.83, NNT 25,for surgery. Conclusions: Treatment wi th a proton pump inhibitor reduces the risk of rebleeding and the requirement fo r surgery after ulcer bleeding but has no benefit on overall mortality.

Objective: To evaluate the role of the enzyme-linked immunosorbent assay (ELISA) test for the detection of antibodies to desmoglein 1 (dsg1) and desmoglein 3 (dsg3) in the diagnosis of pemphigus vulgaris (Pv), and its correlation with disease severity and clinical presentation (mucosal Pv, cutaneous Pv, mucocutaneous Pv). Methods: Twenty-seven active Pv patients and 26 controls with other dermatologic disorders were included in the study. The severity of oral and cutaneous involvement was assessed and recorded. ELISA test for the measurement of anti-dsg1 and anti-dsg3 antibodies was performed (Medical and Biological Laboratories Co. Ltd., Nagoya, Japan). The cut-off ELISA value for both anti-dsg1 and anti-dsg3 was taken as 20. Results: Of the 27 patients, 26 were ELISA positive for anti-dsg1 antibodies and 23 for anti-dsg3 antibodies. Of the controls, two were positive for anti-dsg1 and none for anti-dsg3 antibodies. The sensitivity and specificity of ELISA for anti-dsg1 in the diagnosis of Pv were 96.3% and 92.3% , respectively. For anti-dsg3, they were 85.2% and 100% , respectively. The different morphologic types of Pv could not be differentiated on the basis of antibody profile; however, a direct correlation between anti-dsg3 titers and the severity of oral disease was noted, and also between antidsg1 titers and the severity of cutaneous disease. Conclusions: ELISA (dsg1 and dsg3) is an efficient tool for confirming the diagnosis of Pv. Specific antibody titers correlate with disease severity; however, desmoglein testing cannot differentiate between the various morphologic subtypes of Pv.

A column study was carried out to assess the influence of accompanying anions on potassium （k） leaching at potato growing sites with different soil textures （sandy loam and clay loam） in northwestern India. Potassium was applied in the top 15 cm layer of soil column at 30 and 60 mg k kg-1 through different sources having different accompanying anions （CI-, SO^-, NO3 and H2PO4-）. Maximum k was retained in the top 0-15 cm layer with a sharp decrease in k content occurring in 15 30 cm layer of the soil column. The trend was similar for both levels of applied k as well as frequency of leaching and soil type. The decrease of k content in soil column after four leaching events was maximum in case of khanaura sandy loam, while only minor decrease was observed in Hundowal clay loam when k was applied at 60 mg k kg-1, indicating higher potential of clay rich soil to adsorb k. In general, the k leaching in presence of the accompanying anions followed the order of SO4^2-≤ H2PO42- 〈 NO3 = Cl-. Highest 1 mol·L^-1 CH3COONH4-extractable k was retained when k was applied along with SO4^2- and H2PO4 anions, and the least was retained when accompanying anion was Cl-. The influence of anions was more pronounced in the light textured soil and at high amounts of k application. Higher levels of k application resulted in higher losses of k, especially in sandy loam soil as observed from the leachate concentration. Among the different k sources, the maximum amount of k leaching was noticed in the soil column amended with kC1. After four leachings, the maximum amount of k leached out was 6.40 mg L-1 in Hundowal clay loam and 9.29 mg L-1 in khanaura sandy loam at 60 mg k kg-1 of soil application through kC1. These concentrations were lower than the recommended guideline of the World Health Organisation （12.00 mg L-1）.
