Periarterial Fat Stranding as a Diagnostic Marker for Visceral Disseminated Varicella-Zoster Virus Infection.

A 61-year-old man who underwent allogeneic bone marrow transplantation presented to our hospital with severe abdominal pain and no significant rash. Computed tomography revealed periarterial fat stranding around the celiac and superior mesenteric arteries. Skin and gastric biopsies revealed varicella-zoster virus (VZV) infection, leading to the diagnosis of VZV infection.

Significance of Desmoplastic Histopathological Growth Pattern for Colorectal Liver Metastases Treated With Preoperative Chemotherapy.

Background/aim: The aim of this study was to evaluate hepatectomy cases that underwent preoperative chemotherapy to examine the relationship between the development of desmoplastic histopathological growth pattern (dHGP) and prognosis and recurrence and determine whether it is useful for evaluating preoperative chemotherapy.

Patients And Methods: A total of 133 cases with hepatic metastasis for colorectal cancer that underwent surgical resection.

Results: Of the 102 cases that underwent preoperative chemotherapy, 34 (33%) were determined to be dHGP positive, which was statistically significantly higher than the 2 of 31 cases (6.

Photocatalytic Conversion of Nitrogen to Ammonia with Water on Surface Oxygen Vacancies of Titanium Dioxide.

Ammonia (NH) is an essential chemical in modern society. It is currently manufactured by the Haber-Bosch process using H and N under extremely high-pressure (>200 bar) and high-temperature (>673 K) conditions. Photocatalytic NH production from water and N at atmospheric pressure and room temperature is ideal.

Preventive effects of amino-acid-rich elemental diet Elental® on chemotherapy-induced oral mucositis in patients with colorectal cancer: a prospective pilot study.

Purpose: The prospective pilot study was designed to evaluate the preventive effects of amino-acid-rich elemental diet (ED), Elental(®), on chemotherapy-induced oral mucositis in patients with colorectal cancer. The factors influencing its efficacy are also investigated.

Methods: A total of 22 eligible patients with colorectal cancer experiencing grade 1-3 oral mucositis during treatment with fluorouracil-based chemotherapy entered the current study.

Hyperthermia in the treatment of recurrent abdominal desmoid tumor.

The most suitable management of recurrent abdominal desmoid tumor is still unclear. A case of recurrent huge abdominal desmoid tumor successfully treated by hyperthermia therapy is described. A 63-year-old man was operated upon for desmoid tumor in the retroperitoneum involving pancreas, posterior wall of the stomach and transverse mesocolon in 2007.

One-pot synthesis of imines from nitroaromatics and alcohols by tandem photocatalytic and catalytic reactions on Degussa (Evonik) P25 titanium dioxide.

Photoirradiation (λ > 300 nm) of Degussa (Evonik) P25 TiO2, a mixture of anatase and rutile particles, in alcohols containing nitroaromatics at room temperature produces the corresponding imines with very high yields (80-96%). Other commercially available anatase or rutile TiO2 particles, however, exhibit very low yields (<30%). The imine formation involves two step reactions on the TiO2 surface: (i) photocatalytic oxidation of alcohols (aldehyde formation) and reduction of nitrobenzene (aniline formation) and (ii) condensation of the formed aldehyde and aniline on the Lewis acid sites (imine formation).

Photocatalytic hydrogenolysis of epoxides using alcohols as reducing agents on TiO2 loaded with Pt nanoparticles.

Photoexcitation (λ > 300 nm) of TiO2 loaded with Pt particles promotes selective hydrogenolysis of epoxides using alcohols as reducing agents.
