Article Synopsis
  • Plants have a special substance called ascorbate that helps them stay healthy, especially in their leaves.
  • Over time, plants have learned to make more ascorbate, but scientists aren’t sure how this happened without harming them.
  • The way plants make ascorbate has changed from needing stress to needing light, and some plants have traded one protective enzyme for a different one to help them handle ascorbate safely.

Background: Although the therapeutic relationship (or 'alliance') is well known to be a key component of psychiatric treatment, there has been no simple way to objectively measure the patient-therapist relationship. Here, we measured the psychological distance between patients and their therapists by using the Pictorial Representation of Illness and Self Measure (PRISM).

Patients And Methods: We analyzed the patient-therapist relationship of 112 patients from two hospitals in Japan (54 males, 57 females, 1 unknown; age 46.

Ascorbate plays an indispensable role in plants, functioning as both an antioxidant and a cellular redox buffer. It is widely acknowledged that the ascorbate biosynthesis in the photosynthetic tissues of land plants is governed by light-mediated regulation of the D-mannose/L-galactose (D-Man/L-Gal) pathway. At the core of this light-dependent regulation lies the VTC2 gene, encoding the rate-limiting enzyme GDP-L-Gal phosphorylase.

Workplace violence (WPV) in healthcare settings has drawn attention for over 20 years, yet few studies have investigated the association between WPV and psychological consequences. Here, we used a cross-sectional design to investigate (1) the 12-month prevalence of workplace violence (WPV), (2) the characteristics of WPV, and (3) the relationship between WPV and burnout/secondary traumatic stress among 599 mental healthcare nurses (including assistant nurses) from eight hospitals. Over 40% of the respondents had experienced WPV within the past 12 months.

Background: Combining a thiopurine with the human anti-tumour necrosis factor-α monoclonal antibody adalimumab for Crohn's disease [CD] treatment is controversial with regard to efficacy and safety. By conducting a subanalysis of a multicentre, randomised, prospective, open-label trial [the DIAMOND study, UMIN registration number 000005146], we studied the risk of discontinuation of thiopurine in combination with adalimumab.

Methods: In the preceding DIAMOND study, we analysed the: [i] timing and reasons for dropout in the monotherapy group and combination group; [ii] risk factors for dropout in the combination group.

Background: A 60-year-old female with multiple carotid aneurysms underwent endovascular treatment with a Pipeline Flex embolization device (PED) under local anesthesia via femoral puncture.

Case Description: Cardiac arrest occurred when the delivery systems were pushed to promote adequate opening and apposition of the PED against the vessel wall and was recovered to sinus rhythm in approximately 30 seconds by pulling down the microcatheter. The carotid sinus reflex was suspected as the cause of this temporary asystole.

Article Synopsis
  • - The study aimed to investigate whether a concurrent elemental diet (ED) improves outcomes for Crohn's disease patients already receiving anti-tumor necrosis factor-α (anti-TNF) therapy.
  • - A total of 72 Crohn's disease patients who responded to initial anti-TNF treatment were divided into two groups: one following the ED and the other not; the primary outcome measured was the remission rate after 2 years.
  • - Results showed no significant difference in cumulative remission rates between the ED group (60.9%) and the non-ED group (56.7%), suggesting that the addition of ED did not enhance treatment outcomes for these patients.

Ribosome biogenesis is one of the most energy-consuming events in the cell and must therefore be coordinated with changes in cellular energy status. Here, we show that the sugar-inducible gene () encodes a Pumilio homology domain-containing protein involved in pre-rRNA processing in Null mutation of resulted in aborted embryos due to abnormal gametogenesis and embryogenesis, whereas reduced expression of caused several phenotypes characteristic of ribosome biogenesis or function-related mutants. APUM24 interacted with other pre-rRNA processing factors and a putative endonuclease for the removal of the internal transcribed spacer 2 (ITS2) of pre-rRNA in the nucleolus.

Rationale And Objectives: Pulmonary involvement in inflammatory bowel disease may reflect the common embryonic origin of the gastrointestinal tract and the bronchial tree. No studies have compared pulmonary high-resolution computed tomography (HRCT) findings between ulcerative colitis (UC) and Crohn disease (CD). This study aimed to assess the relationship between pulmonary HRCT findings and inflammatory bowel disease activity and to compare HRCT findings between UC and CD.

Background & Aims: We previously reported results from a prospective randomized controlled trial comparing the efficacy of adalimumab monotherapy versus combination with azathioprine for patients with Crohn's disease (CD) who were naive to biologics and thiopurines. We performed a subanalysis of data from this study to evaluate factors associated with endoscopic response and mucosal healing in study participants.

Methods: We compared simple endoscopic scores for CD between patients with moderate to severe active CD randomly assigned groups that received adalimumab monotherapy (n = 85) or adalimumab in combination with azathioprine (n = 91), from June 2011 to June 2014 in Japan.

It has been reported that treatment with yeast cell wall extract (YCWE) induces PDF1 and PR-1 gene expression; these transcripts are important markers of plant disease resistance, though the detailed signaling mechanisms that induce these defense responses are still unknown. In this report, we found that YCWE treatment triggered rice cell suspension cultures to accumulate phenylalanine (Phe), cis-12-oxo-phytodienoic acid (OPDA), 12-hydroxyjasmonoyle isoleucine (12OHJA-Ile), and azelaic acid (AzA). YCWE treatment also reduced endogenous triacylglycerol (TG) content.

A 62-year-old man with epigastralgia was referred to our hospital for the evaluation of an intractable duodenal ulcer, which did not improve following proton pump inhibitor treatment. An upper gastrointestinal endoscopy revealed that the base of the ulcer was gray-white in color with conspicuous fibrosis tissue, unlike the appearance of common ulcers. A contrast-enhanced abdominal CT scan and angiography revealed tortuous and dilated vascular structures in the pancreatic head.

Nitrate modulates growth and development, functioning as a nutrient signal in plants. Although many changes in physiological processes in response to nitrate have been well characterized as nitrate responses, the molecular mechanisms underlying the nitrate response are not yet fully understood. Here, we show that NLP transcription factors, which are key regulators of the nitrate response, directly activate the nitrate-inducible expression of BT1 and BT2 encoding putative scaffold proteins with a plant-specific domain structure in Arabidopsis.

Gastric fundic gland polyps (FGPs) are common non-adenomatous gastric polyps arising from normal fundic mucosa without () infection. Although systemic FGPs associated with familial adenomatous polyposis (FAP) often have dysplasia, there are few reports of dysplasia occurring in sporadic FGPs, especially when detected by magnifying endoscopy with narrow band imaging (ME-NBI). We experienced two cases of adenocarcinoma occurring in sporadic FGPs, and their ME-NBI findings were very useful for differentiating FGP with cancer from non-dysplastic FGP.

Group A1 heat shock transcription factors (HsfA1s) are the master regulators of the heat stress response (HSR) in plants. Upon heat shock, HsfA1s trigger a transcriptional cascade that is composed of many transcription factors. Despite the importance of HsfA1s and their downstream transcriptional cascade in the acquisition of thermotolerance in plants, the molecular basis of their activation remains poorly understood.
