Exogenous application of the apocarotenoid retinaldehyde negatively regulates auxin-mediated root growth.

Root development is essential for plant survival. The lack of carotenoid biosynthesis in the phytoene desaturase 3 (pds3) mutant results in short primary roots (PRs) and reduced lateral root formation. In this study, we showed that short-term inhibition of PDS by fluridone suppresses PR growth in wild type, but to a lesser extent in auxin mutants of Arabidopsis (Arabidopsis thaliana).

Periodic cytokinin responses in rhizobium infection and nodule development.

Host plants benefit from legume root nodule symbiosis with nitrogen-fixing bacteria under nitrogen-limiting conditions. In this interaction, the hosts must regulate nodule numbers and distribution patterns to control the degree of symbiosis and maintain root growth functions. The host response to symbiotic bacteria occurs discontinuously but repeatedly at the region behind the tip of the growing roots.

Endoscopic ultrasound-guided fine needle biopsy diagnosis of circumferentially extraluminal mucosa-associated lymphoid tissue lymphoma in the transverse colon: a case report.

A 61-year-old man present to us with continued abdominal pain without abdominal tenderness for 1 month. Blood testing showed elevated biliary enzymes and inflammation. Contrast-enhanced computed tomography (CT) revealed thickening of the transverse colon with relatively strong enhancement but no bile duct dilatation.

Incidental detection of upper gastrointestinal epithelial neoplasia by screening endoscopy prior to endoscopic ultrasonography in patients with pancreaticobiliary disease.

Background: Screening esophagogastroduodenoscopy plays an important role in the early detection of upper gastrointestinal cancer. To provide more opportunities for patients with pancreaticobiliary disease to undergo this screening, we have performed esophagogastroduodenoscopy prior to endoscopic ultrasonography. However, the usefulness of this protocol is not elucidated.

Circadian Clock Controls Root Hair Elongation through Long-Distance Communication.

Plants adapt to periodic environmental changes, such as day and night, by using circadian clocks. Cell division and elongation are primary steps to adjust plant development according to their environments. In Arabidopsis, hypocotyl elongation has been studied as a representative model to understand how the circadian clock regulates cell elongation.

Neurofibroma with adenosis in the mammary gland: a case report.

Background: Neurofibroma of the breast is extremely rare, with only a few reported cases. Here, we report a case of solitary neurofibroma of the breast in a 95-year-old woman.

Case Presentation: A 95-year-old woman presented with a palpable mass in the left breast.

Gallbladder perforation following peroral cholangioscopy-guided lithotripsy: A case report.

Peroral cholangioscopy-guided lithotripsy is highly effective in clearing difficult bile duct stones. It can cause adverse events, such as cholangitis and pancreatitis; however, gallbladder perforation is extremely rare. Herein, we describe the case of a 77-year-old woman who developed gallbladder perforation following peroral cholangioscopy -guided lithotripsy.

3-Phenyllactic acid is converted to phenylacetic acid and induces auxin-responsive root growth in Arabidopsis plants.

Many microorganisms have been reported to produce compounds that promote plant growth and are thought to be involved in the establishment and maintenance of symbiotic relationships. 3-Phenyllactic acid (PLA) produced by lactic acid bacteria was previously shown to promote root growth in adzuki cuttings. However, the mode of action of PLA as a root-promoting substance had not been clarified.

Conjugates of 3-phenyllactic acid and tryptophan enhance root-promoting activity without adverse effects in .

3-Phenyllactic acid (PLA) is a common secondary product of sp. and promotes adventitious-root formation in Azuki beans (). Root promotion activity of PLA is synergistically enhanced by tryptophan (Trp).

Endoscopic ultrasound-guided fine-needle biopsy for the diagnosis of gastric metastasis from breast cancer mimicking primary linitis plastica: A case report.

For gastric lesions in a patient with a history of breast cancer, it is essential to distinguish between primary gastric cancer and gastric metastasis from breast cancer. However, gastric metastasis from breast cancer often mimics primary linitis plastica, and histological diagnosis may be difficult with conventional endoscopic biopsies. Herein, we describe the case of a 75-year-old woman who presented at our hospital with epigastralgia and vomiting.

A PSTAIRE-type cyclin-dependent kinase controls light responses in land plants.

Light is a critical signal perceived by plants to adapt their growth rate and direction. Although many signaling components have been studied, how plants respond to constantly fluctuating light remains underexplored. Here, we showed that in the moss () , the PSTAIRE-type cyclin-dependent kinase PpCDKA is dispensable for growth.

Takotsubo cardiomyopathy after hypoglycemia in a patient with anorexia nervosa.

Background: Takotsubo cardiomyopathy, also known as "apical ballooning syndrome", is generally precipitated by endogenous or exogenous stress. Eating disorders are associated with a variety of physical complications.

Case Presentation: We present a case involving a 37-year-old Japanese female with anorexia nervosa.

Detection of Legionella species, the influence of precipitation on the amount of Legionella DNA, and bacterial microbiome in aerosols from outdoor sites near asphalt roads in Toyama Prefecture, Japan.

Background: Legionellosis is caused by the inhalation of aerosolized water contaminated with Legionella bacteria. In this study, we investigated the prevalence of Legionella species in aerosols collected from outdoor sites near asphalt roads, bathrooms in public bath facilities, and other indoor sites, such as buildings and private homes, using amoebic co-culture, quantitative PCR, and 16S rRNA gene amplicon sequencing.

Results: Legionella species were not detected by amoebic co-culture.

3-Phenyllactic acid, a root-promoting substance isolated from Bokashi fertilizer, exhibits synergistic effects with tryptophan.

Bokashi fertilizer, an organic fertilizer made of plant residue, has been used in Japan not only to fertilize plants but to regulate their growth. Lactic acid bacteria have been found to play an important role in the fermentation process of Bokashi, but the relationship between these bacteria and plant growth activity has not been clarified. Using the adzuki rooting assay, this study identified 3-phenyllactic acid (PLA) produced by lactic acid bacteria as a root promoting compound in Bokashi.

Subtype Screening of bla Genes Using Bipartite Primers for DNA Sequencing.

Genes conferring carbapenem resistance have spread worldwide among gram-negative bacteria. Subtyping of these genes has epidemiological value due to the global cross-border movement of people. Subtyping of bla genes that frequently detected in Japan appears to be important in public health settings; however, there are few useful tools for this purpose.

ZEITLUPE enhances expression of PIF4 and YUC8 in the upper aerial parts of Arabidopsis seedlings to positively regulate hypocotyl elongation.

Microarray and genetic analyses reveal that ZTL induces the expression of genes related to auxin synthesis, thereby promoting hypocotyl elongation. ZTL is a blue-light receptor that possesses a light-oxygen-voltage-sensing (LOV) domain, an F-box motif, and a kelch repeat domain. ZTL promotes hypocotyl elongation under high temperature (28 °C) in Arabidopsis thaliana; however, the mechanism of this regulation is unknown.

Comparing the Heart-Thigh and Thigh-Ankle Arteries with the Heart-Ankle Arterial Segment for Arterial Stiffness Measurements.

Purpose: The cardio-ankle vascular index, applying the stiffness parameter β theory, was calculated using the pulse-wave velocity and blood pressure from the aortic orifice to the ankle. Accordingly, the impact of the stiffness of the aorta [heart-thigh β (htBETA)] and medium-sized muscular artery [thigh-ankle β (taBETA)] on the stiffness of the heart-ankle β (haBETA) was investigated; further, whether the htBETA (haBETA - taBETA) improved the power of diagnosis of coronary artery disease (CAD) was examined.

Materials And Methods: Segmental βs were calculated using VaSela with an additional thigh cuff and compared using the receiver operating characteristic (ROC) curve analysis to evaluate CAD.

Malignant solitary fibrous tumor of the pancreas: a case report.

Background: Solitary fibrous tumors (SFTs) are rare tumors, mostly derived from connective tissue mesenchymal cells that arise from the pleura. There are very few reports of primary pancreatic SFT. Preoperative diagnosis is difficult owing to the lack of distinctive radiological findings.
