Novel Approach to the Construction of Fused Indolizine Scaffolds: Synthesis of Rosettacin and the Aromathecin Family of Compounds.

Camptothecin-like compounds are actively employed as anticancer drugs in clinical treatments. The aromathecin family of compounds, which contains the same indazolidine core structure as the camptothecin family of compounds, is also expected to display promising anticancer activity. Therefore, the development of a suitable and scalable synthetic method of aromathecin synthesis is of great research interest.

Inter-professional and inter-departmental alcoholism rehabilitation program.

A 3-month alcoholism rehabilitation program at psychiatric hospitals is common in Japan for patients with alcohol use disorder (AUD). However, many AUD patients are often hospitalized for the treatment of digestive disorders due to alcohol-related liver diseases and pancreatitis. In this sense, AUD patients need to be better supported by professionals and departments in general hospitals.

Hepatocellular carcinoma in an adult patient with congenital absence of the portal vein type II: A case report.

Congenital absence of the portal vein (CAPV) is a rare malformation in which intestinal and splenic venous blood bypasses the liver and drains into systemic veins. CAPV is classified into two types based on the absence (type I) or presence (type II) of portal venous flow into the hepatic parenchyma and is associated with multiple other anomalies such as usually benign hepatic tumors. There have been only two case reports describing hepatocellular carcinoma (HCC) in patients with CAPV type II to date.

Image processing analysis of oral cancer, oral potentially malignant disorders, and other oral diseases using optical instruments.

Oral cancer screening is important for early detection and early treatment, which help improve survival rates. Biopsy is invasive and painful, while fluorescence visualization using optical instruments is non-invasive, convenient, and provides results in real time, and examinations can be repeated. The purpose of this study was to determine the usefulness of optical instruments in oral screening.

Remarkable response to abiraterone acetate in castration-resistant prostate cancer patient with aggressive liver metastasis.

Introduction: The number of treatment options for metastatic castration-resistant prostate cancer has increased in recent years. Abiraterone, which selectively inhibits CYP17 in the androgen synthesis pathway, is widely used. Liver metastasis is one of the worst prognostic factors in metastatic castration-resistant prostate cancer.

A prospective multicenter study on genome wide associations to ranibizumab treatment outcome for age-related macular degeneration.

We conducted a genome-wide association study (GWAS) on the outcome of anti-VEGF treatment for exudative age-related macular degeneration (AMD) in a prospective cohort. Four hundred and sixty-one treatment-naïve AMD patients were recruited at 13 clinical centers and all patients were treated with 3 monthly injections of ranibizumab followed by pro re nata regimen treatment for one year. Genomic DNA was collected from all patients for a 2-stage GWAS on achieving dry macula after the initial treatment, the requirement for an additional treatment, and visual acuity changes during the 12-month observation period.

Ureteral Stone in the Distal Blind-ending Branch of a Bifid Ureter.

A bifid ureter with a distal blind-ending branch is a rare congenital anomaly. Most patients are asymptomatic; only patients with complications, such as infection, vesicoureteral reflux, or stone formation, present symptoms. We describe the case of a patient with urinary stone located in the distal blind-ending branch of a bifid ureter diagnosed during transurethral lithotripsy.

Clinical and molecular characteristics of East Asian patients with von Hippel-Lindau syndrome.

Background: Von Hippel-Lindau (VHL) syndrome is a dominantly inherited multisystem cancer syndrome caused by a heterozygous mutation in the VHL tumor suppressor gene. Previous studies suggested that similar populations of Caucasian and Japanese patients have similar genotype or phenotype characteristics. In this comprehensive study of East Asian patients, we investigated the genetic and clinical characteristics of patients with VHL syndrome.

Effect of Ang-2-VEGF-A Bispecific Antibody in Renal Cell Carcinoma.

The blockade of VEGF pathway has been clinically validated as an initial treatment for renal cell carcinoma (RCC). Angiopoietin-2 (Ang-2) has been indicated as a key regulator for angiogenesis escape. The effect of a novel bispecific antibody (A2V CrossMab) against both Ang-2 and VEGF was investigated in comparison with either factor.

Inhibition of placental growth factor in renal cell carcinoma.

Background/aim: Placental growth factor (PlGF) is up-regulated in major malignant diseases or following antiangiogenic therapy, although it is present in low levels under normal physiological conditions. TB403, a monoclonal antibody against PlGF, was investigated in clear cell renal cell carcinoma (ccRCC) xenografts since it has been proposed as a potential target in oncology.

Materials And Methods: Human ccRCCs were implanted in athymic nude mice to evaluate the efficacy of TB403 and to excise xenograft tumors for molecular experiments.

A method to obtain the absorption coefficient spectrum of single grain coal in the aliphatic C-H stretching region using infrared transflection microspectroscopy.

A method was developed to obtain the absorption coefficient spectrum of a grain of coal (as small as 10(-7)) in the region of aliphatic and aromatic C-H stretching bands (2700-3200 cm(-1)) using infrared transflection microspectroscopy. In this method, the complex refractive index n - ik was determined using an optimization algorithm with the Kramers-Kronig transform so that the calculated transflection spectrum from the Fresnel equation corresponded to the measured one. The obtained absorption coefficients were compared with the bulk values determined from the potassium bromide (KBr) pellet measurement method.

The association of CD36 variants with polypoidal choroidal vasculopathy compared to typical neovascular age-related macular degeneration.

Purpose: To clarify the association of cluster of differentiation 36 (CD36) variants with polypoidal choroidal vasculopathy (PCV) and compare them with those in typical neovascular age-related macular degeneration (tAMD).

Methods: We included 349 Japanese AMD patients (210 PCV, 139 tAMD) and 198 age-matched controls. Four tag single-nucleotide polymorphisms (SNPs)-rs10499862, rs3173798, rs3211883, and rs3173800-in the CD36 region were genotyped using the TaqMan assay.

[Myocardial metastasis from renal cell carcinoma treated with sorafenib].

We present a case of myocardial metastasis from renal cell carcinoma (RCC) during the treatment with sorafenib. A 63-year-old male, who had undergone right radical nephrectomy, received interferon-alpha (IFN), interleukin (IL-2) and 5-flurouracil (5-FU) for the treatment of lung and pleural metastases. However, since this metastasis showed progressive disease, we administered sorafenib.
