Testicular rhabdomyosarcoma after chemotherapy for metastatic germ cell tumors.

A 36-year-old male was referred to our hospital with left scrotal swelling. Computed tomography revealed a massive tumor in his left scrotum. The tumor extended along the gonadal vein extraperitoneally forming a massive tumor.

H3K14 ubiquitylation promotes H3K9 methylation for heterochromatin assembly.

The methylation of histone H3 at lysine 9 (H3K9me), performed by the methyltransferase Clr4/SUV39H, is a key event in heterochromatin assembly. In fission yeast, Clr4, together with the ubiquitin E3 ligase Cul4, forms the Clr4 methyltransferase complex (CLRC), whose physiological targets and biological role are currently unclear. Here, we show that CLRC-dependent H3 ubiquitylation regulates Clr4's methyltransferase activity.

Expression of fatty-acid-binding protein 5 in intrahepatic and extrahepatic cholangiocarcinoma: the possibility of different energy metabolisms in anatomical location.

The biliary tract cancer (BTC) covers a range of carcinomas, including intrahepatic cholangiocarcinoma (ICC), cholangiolocellular carcinoma (CoCC), perihilar cholangiocarcinoma (perihilar CC), extrahepatic cholangiocarcinoma (ECC), and gallbladder cancer (GBC), defined according to the anatomical location. These adenocarcinomas mostly comprise biliary epithelial cell-derived malignant cells. In addition to anatomical differences, there are morphological and biological differences in BTC starting from embryonic development of the tissues extending to physiological differences.

Relationship between the subtypes of child abuse and affective temperaments: Comparison of depression and bipolar disorder patients and healthy controls using the reclassified Child Abuse and Trauma Scale.

Background: We previously reported that child abuse indirectly predicts the diagnosis of major depressive disorder (MDD) or bipolar disorder (BP) based on higher scores of affective temperaments; however, the subtypes of child abuse have not been examined sufficiently. Therefore, in the present study, we used the reclassified version of the Child Abuse and Trauma Scale (CATS) to determine how the subtypes of child abuse affect affective temperaments.

Methods: A total of 502 participants (212 healthy controls, 163 patients with MDD and 127 patients with BP) were administered the Japanese version of the CATS; the Japanese version of the Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Autoquestionnaire; and the Japanese version of the Patient Health Questionnaire-9.

Long QT syndrome with a de novo CALM2 mutation in a 4-year-old boy.

Background: Human calmodulin (CALM) gene mutation has been reported to be related to inherited arrhythmia syndromes, but the genotype-phenotype relationship remains unclear.

Methods And Results: We report here a 4-year-old boy who had cardiac arrest while playing in a kindergarten playground. Cardiopulmonary resuscitation was initiated immediately.

Significance of urinary albumin excretion in patients with cast nephropathy .

Background: This study was performed to determine whether the urinary albumin excretion rate (%UAE) could distinguish myeloma cast nephropathy (MCN) without glomerular amyloid deposition from MCN with glomerular amyloid deposition.

Materials And Methods: We retrospectively reviewed clinicopathological data on 16 patients with MCN diagnosed by renal biopsy at Toranomon Hospital from 2004 to 2014.

Results: A total of 10 patients had pure MCN without glomerular amyloid deposition (group 1), and 6 patients had MCN with glomerular amyloid deposition (group 2).

The R2TP complex regulates paramyxovirus RNA synthesis.

The regulation of paramyxovirus RNA synthesis by host proteins is poorly understood. Here, we identified a novel regulation mechanism of paramyxovirus RNA synthesis by the Hsp90 co-chaperone R2TP complex. We showed that the R2TP complex interacted with the paramyxovirus polymerase L protein and that silencing of the R2TP complex led to uncontrolled upregulation of mumps virus (MuV) gene transcription but not genome replication.

Drowning of a patient with epilepsy while showering.

In Japan, because the most common site of drowning among patients with epilepsy is the bathtub, showering is generally recommended as an alternative to bathing. We herein report a case involving a female patient with epilepsy who drowned while showering. She had been diagnosed with epilepsy approximately 25 years previously, and her condition had progressed to refractory epilepsy.

Chronic Atrial and Ventricular Pacing in the Mouse.

Background: The mouse is the most widely used mammal in experimental biology. Although many clinically relevant in vivo cardiac stressors are used, one that has eluded translation is long-term cardiac pacing. Here, we present the first method to chronically simulate and simultaneously record cardiac electrical activity in conscious mobile mice.

Efficacy of combined prophylactic use of levofloxacin and isepamicin for transrectal prostate needle biopsy: A retrospective single-center study.

Purpose: To assess the efficacy of a combined regimen of levofloxacin (LVFX) plus isepamicin (ISP) as prophylaxis for transrectal ultrasound-guided needle biopsy of the prostate (TRUSP-Bx).

Materials And Methods: Overall, 562 patients undergoing TRUSP-Bx were included in the present study. All patients were administered a single-dose of oral LVFX (500 mg) in the morning and intravenous ISP (400 mg) 60 min before biopsy.

CD4 T cells from patients with primary biliary cholangitis show T cell activation and differentially expressed T-cell receptor repertoires.

Aim: Primary biliary cholangitis (PBC) is an autoimmune liver disease with unknown pathogenesis. In PBC, activation of T-cell receptor (TCR) signaling is associated with inflammatory cytokine production through N-Ras upregulation. Although the CD4 T cell TCR repertoire could be associated with PBC pathogenesis, it has not been evaluated.

Mitotic phosphorylation of HP1α regulates its cell cycle-dependent chromatin binding.

Heterochromatin protein 1 (HP1) is an evolutionarily conserved chromosomal protein that plays a crucial role in heterochromatin-mediated gene silencing. We previously showed that mammalian HP1α is constitutively phosphorylated at its N-terminal serine residues by casein kinase II (CK2), and that this phosphorylation enhances HP1α's binding specificity for nucleosomes containing lysine 9-methylated histone H3 (H3K9me). Although the presence of additional HP1α phosphorylation during mitosis was reported more than a decade ago, its biological significance remains largely elusive.

RABL2 positively controls localization of GPCRs in mammalian primary cilia.

The primary cilium, a solitary protrusion from most mammalian cells, functions as a cell sensor by receiving extracellular signals through receptors and channels accumulated in the organelle. Certain G-protein-coupled receptors (GPCRs) specifically localize to the membrane compartment of primary cilia. To gain insight into the mechanisms that regulate ciliary GPCR sorting, we investigated the atypical small GTPase RAB-like 2 (RABL2; herein referring to the near-identical human paralogs RABL2A and RABL2B).

Protein expression profile and microRNA expression signature in estrogen receptor-positive and -negative breast cancers: report of two cases.
