Distribution and genome structures of temperate phages in acetic acid bacteria.

Acetic acid bacteria (AAB) are industrial microorganisms used for vinegar fermentation. Herein, we investigated the distribution and genome structures of mitomycin C-inducible temperate phages in AAB. Transmission electron microscopy analysis revealed phage-like particles in 15 out of a total 177 acetic acid bacterial strains, all of which showed morphology similar to myoviridae-type phage.

Usefulness of virtual touch tissue quantification for predicting the presence of esophageal varices in patients with liver cirrhosis.

Background And Aim: Measuring the hepatic venous pressure gradient (HVPG) is an established technique to detect increased portal pressure and predict the presence of esophageal varices (EVs); however, the risk of the test is greater than the information it provides. This study aimed to clarify the usefulness of virtual touch tissue quantification (VTQ), which assesses liver stiffness, in predicting the presence of EVs in patients with liver cirrhosis by comparing it with HVPG.

Methods: Two hundred seventeen patients with liver cirrhosis underwent VTQ, HVPG measurement, and upper endoscopy.

Mutated GM-CSF-based CAR-T cells targeting CD116/CD131 complexes exhibit enhanced anti-tumor effects against acute myeloid leukaemia.

Objectives: As the prognosis of relapsed/refractory (R/R) acute myeloid leukaemia (AML) remains poor, novel treatment strategies are urgently needed. Clinical trials have shown that chimeric antigen receptor (CAR)-T cells for AML are more challenging than those targeting CD19 in B-cell malignancies. We recently developed -modified ligand-based CAR-T cells that target CD116/CD131 complexes, also known as the GM-CSF receptor (GMR), for the treatment of juvenile myelomonocytic leukaemia.

Interspecific social dominance networks reveal mechanisms promoting coexistence in sympatric charr in Hokkaido, Japan.

Coexistence of species requires equalizing mechanisms that minimize fitness differences, which are balanced by stabilizing mechanisms that enhance negative intraspecific interactions versus interspecific ones. Here, we develop a simple theoretical framework that allows measuring the relative strength of intraspecific versus interspecific competition in dominance hierarchies. We use it to evaluate mechanisms promoting coexistence between two congeneric charr that compete for foraging positions, which strongly influence density-dependent growth and survival.

[Thrombectomy for right atrial thrombosis complicating a pyogenic liver abscess].

Vascular complications from a liver abscess are rare but life-threatening. Herein, we report the case of a man in his 40s with a pyogenic hepatic abscess complicated by an inferior vena caval thrombus extending to the right atrium. His presenting complaint was a high fever.

Repeated Stereotactic Body Radiation Therapy for Hepatocellular Carcinoma.

Purpose: In clinical practice, whether cirrhotic livers in patients with hepatocellular carcinoma (HCC) can withstand repeated stereotactic body radiation therapy (SBRT) remains unclear. This study aimed to evaluate the outcomes and toxicities in these patients.

Methods And Materials: This retrospective study included patients with HCC who were treated with SBRT at least twice between January 2012 and June 2019.

Magnitude and direction of stream-forest community interactions change with timescale.

Networks of direct and indirect biotic interactions underpin the complex dynamics and stability of ecological systems, yet experimental and theoretical studies often yield conflicting evidence regarding the direction (positive or negative) or magnitude of these interactions. We revisited pioneering data sets collected at the deciduous forested Horonai Stream and conducted ecosystem-level syntheses to demonstrate that the direction of direct and indirect interactions can change depending on the timescale of observation. Prior experimental studies showed that terrestrial prey that enter the stream from the adjacent forest caused positive indirect effects on aquatic invertebrates during summer by diverting fish consumption.

Japanese mothers' prebirth Adult Attachment Interview predicts their infants' response to the Strange Situation Procedure: The strange situation in Japan revisited three decades later.

The current study investigated the intergenerational transmission of attachment in Sapporo, Japan, using the Adult Attachment Interview (AAI) and the Strange Situation Procedure (SSP). This is the first SSP study in Sapporo in three decades, after a study in the mid-1980s reported controversial results. The SSP distributions found in the current study, however, were similar to those reported in the earlier Sapporo study, including its controversial finding that ambivalent attachment was predominant in insecure infants.

Prevalence of primary aldosteronism without hypertension in the general population: Results in Shika study.

Objective: Recent studies have reported a high prevalence of primary aldosteronism (PA) among hypertensive patients. However, few data exist regarding the prevalence of PA in the general population. Therefore, we examined the prevalence of PA in the general population including normotensive subjects.

Remogliflozin Etabonate Improves Fatty Liver Disease in Diet-Induced Obese Male Mice.

Background: Nonalcoholic fatty liver disease and nonalcoholic steatohepatitis (NASH) are serious conditions and are being diagnosed at an increased rate. The etiology of these hepatic disorders is not clear but involves insulin resistance and oxidative stress. Remogliflozin etabonate (Remo) is an inhibitor of the sodium glucose-dependent renal transporter 2 (SGLT2), and improves insulin sensitivity in type 2 diabetics.

Arrival time parametric imaging of the hemodynamic balance changes between the hepatic artery and the portal vein during deep inspiration, using Sonazoid-enhanced ultrasonography: A case of Budd-Chiari syndrome.

This case report concerns a 40-year-old male who had previously been treated for an esophageal varix rupture, at the age of 30 years. The medical examination at that time revealed occlusion of the inferior vena cava in the proximity of the liver, leading to the diagnosis of the patient with Budd-Chiari syndrome. The progress of the patient was therefore monitored in an outpatient clinic.

Visualization of segmental arterialization with arrival time parametric imaging using Sonazoid-enhanced ultrasonography in portal vein thrombosis: A case report.

A 55-year-old male was admitted in mid-April 2011 with a fever of >39°C and pain in the lower right abdomen. A medical examination revealed sepsis originating from colonic diverticulitis. Abdominal B-mode ultrasonography (US) performed on admission detected thrombi in the superior mesenteric vein and in the right branch of the hepatic portal vein.

Short-term effects and early complications of balloon-occluded retrograde transvenous obliteration for gastric varices.

The short-term effects of balloon-occluded retrograde transvenous obliteration (BRTO) to treat gastric varices were evaluated by using computed tomography (CT) and gastroscopy (GF). The subjects were 77 patients who underwent BRTO to treat gastric varices. The short-term effects of BRTO were investigated with regard to ascites, pleural effusion, venous thrombus, and esophageal varices by comparing the findings of CT and GF performed within one month before and after BRTO.

Heterotopic Pancreas of the Jejunum Incidentally Detected by Preoperative Abdominal CT: Report of Two Cases and Review of the Literature.

Heterotopic pancreas (HP) is typically an asymptomatic malformation that can present anywhere along the gastrointestinal tract. It is often detected incidentally on surgery for other diseases or autopsy. We encountered 2 patients with jejunal HP incidentally detected by computed tomography (CT) performed for close evaluation of other diseases.

Clinical evaluation of hemorrhagic gastroduodenal ulcer in the elderly: is Helicobacter pylori infection a risk factor for hemorrhage?

Aim: In this study, the aim was to determine the demographic characteristics of elderly patients with gastroduodenal ulcer who had undergone endoscopic hemostasis by comparing them with younger patients.

Methods: A total of 353 patients with Forrest class I-IIa hemorrhagic gastroduodenal ulcer who underwent endoscopic hemostasis at our hospital between December 2004 and May 2010 were divided into two groups: one for those 75 years or older (old-old group; n = 71; age ≥75 years) and one for those younger than 75 years (younger group; n = 282; age <75 years). Then, their demographic characteristics were compared.

Specific detection by the polymerase chain reaction of potentially allergenic salmonid fish residues in processed foods.

Salmonid fish is one of the allergenic items that are recommended to be labeled in the Japanese allergen-labeling system. This study develops a salmonid-specific polymerase chain reaction (PCR) method. A new primer pair, SKE-F/SKE-R, was designed to specifically detect the salmonid fish gene encoding mitochondrial DNA cytochrome b.

Gastrointestinal stromal tumor mimicking arteriovenous malformation of the jejunum.

There have been case reports of small intestinal gastrointestinal stromal tumors (GISTs) complicated with arteriovenous malformation (AVM) and angiodysplasia and exhibiting intense tumor staining. Herein we report a GIST of the small intestine that showed tumor staining and early venous return on imaging studies, and so the patient was suspected to have AVM. A 62-year-old male presented with intermittent pain in the left abdominal region.

Specific detection of banana residue in processed foods using polymerase chain reaction.

Specific polymerase chain reaction (PCR) methods were developed for the detection of banana residue in processed foods. For high banana specificity, the primer set BAN-F/BAN-R was designed on the basis of the large subunit of ribulose-1,5-bisphosphate carboxylase (rbcL) genes of chloroplasts and used to obtain amplified products specific to banana by both conventional and real-time PCR. To confirm the specificity of these methods, genomic DNA samples from 31 other species were examined; no amplification products were detected.

Endoscopic snare excision of a major duodenal papillary tumor.

Background/aims: Tumors of the duodenal papilla include hyperplasia, adenoma, carcinoma in adenoma, and carcinoma. Since the duodenal papilla has special anatomical characteristics and treatment involves major intervention, a correct preoperative diagnosis is essential for successful treatment.

Methods: In patients with adenoma or early carcinoma of the papilla, endoscopic snare excision is indicated for complete removal of the tumor.

Carotid atherosclerosis mediated by visceral adiposity and adipocytokines in type 2 diabetic subjects.

The aim of this study was to verify the possible association of visceral fat accumulation with carotid atherosclerosis in order to identify the practical and feasible determinants for each parameter of atherosclerosis in type 2 diabetic subjects. The subjects were 151 diabetic (DM) and age-matched 83 nondiabetic subjects (C), without atherosclerotic disease. Visceral fat area (VFA) on a CT scan at the umbilicus level was measured.

Sergliflozin etabonate, a selective SGLT2 inhibitor, improves glycemic control in streptozotocin-induced diabetic rats and Zucker fatty rats.

The low-affinity sodium glucose cotransporter (SGLT2) is responsible for most of the glucose reabsorption in the kidney and has been highlighted as a novel therapeutic target for the treatment of diabetes. We discovered sergliflozin etabonate, a novel selective SGLT2 inhibitor, and found that selective inhibition of SGLT2 increased urinary glucose excretion and consequently decreased plasma glucose levels. In this report, we examined the antihyperglycemic effects of sergliflozin etabonate in normal and diabetic rats in comparison with those of a sulfonylurea (gliclazide) and an alpha-glucosidase inhibitor (voglibose).

Identification of tumor promotion marker genes for predicting tumor promoting potential of chemicals in BALB/c 3T3 cells.

Tumor promoters can cause development of tumors in initiated cells and the majority of them are non-genotoxic carcinogens. The detection of tumor promoters is important for the prevention of cancer. The in vitro two-stage transformation assay, using BALB/c 3T3 cells, is a useful system, and benefits from a convenient protocol and high predictability of mammalian carcinogenicity.

Orally active factor Xa inhibitors: investigation of a novel series of 3-amidinophenylsulfonamide derivatives using an amidoxime prodrug strategy.

A series of novel and potent 3-amidinophenylsulfonamide derivatives of factor Xa inhibitors were designed and synthesized using an amidoxime prodrug strategy. We focused on systemic clearance of parent compounds in rats, and performed in vivo pharmacokinetic screening. Incorporation of a carboxymethoxy group markedly improved systemic clearance (compound 43), and the related amidoxime 44 showed sufficient prodrug conversion.

AST-120 (Kremezin) initiated in early stage chronic kidney disease stunts the progression of renal dysfunction in type 2 diabetic subjects.

There is little clinical evidence when AST-120 should be prescribed for subjects with early stage overt diabetic nephropathy. We therefore designed a prospective, randomized, controlled study for subjects with type 2 diabetes (serum creatinine <1.5mg/dl and urinary protein >0.
