Microfluidic Fabrication of Morphology-Controlled Polymeric Microspheres of Blends of Poly(4-butyltriphenylamine) and Poly(methyl methacrylate).

Multicomponent polymer particles with specific morphology are promising materials exhibiting novel functionality which cannot be obtained with single-component polymer particles. Particularly, the preparation of such kinds of polymer particles involving electrically or optically active conjugated polymers with uniform size is a challenging subject due to their intense demands. Here, microspheres of binary polymer blend consisting of poly(4-butyltriphenylamine) (PBTPA)/poly(methyl methacrylate) (PMMA) (1:1 in weight) were produced via a microfluidic emulsification with a Y-shaped microreactor, and a subsequent solvent evaporation method.

Formation of Benzimidazoisoquinolinium and Benzimidazoisoindolinum Cyclic Systems by the Reaction of 2-(2-Alkynylphenyl)benzimidazoles with Iodine and Iodine-Iodine Interaction Including Halogen Bonding in Their Crystal Structures.

The reaction of 2-(2-alkynylphenyl)benz[d]imidazoles with molecular iodine constructed 5- and 6-membered rings as novel organic salts in high yield. The constituted number of ring systems was influenced by the substituent at the triple bond: 6-membered rings were formed from compounds bearing aryl substituents, whereas 5-membered ones were obtained from compounds with hydrogen or alkyl substituents. The products were obtained with triiodide as a counteranion; however, compounds with iodide were also obtainable under certain conditions.

[Problems of adjuvant chemotherapy with S-1 for gastric cancer].

From results of ACTS-GC,postoperative adjuvant chemotherapy,administration of S-1 for one year has become the standard for gastric cancer of Stage II and III except T1. We inspected problems of adjuvant chemotherapy by S-1 by dose rate, an adverse event,and compliance. For the period from July 2006 to December 2008,among 41 cases of stage II/stage III gastric cancer, S-1 was as started as adjuvant therapy by for 28 cases (68.

[Side effects of FEC100].

Purpose: The purpose was to investigate side effects of FEC100 treatment, particularly bone marrow suppression, nausea and vomiting.

Patients And Methods: We investigated side effects of FEC100 at the time of initial administration in 49 breast cancer patients (including 3 with recurrence). We used a 5-HT3 receptor antagonist as an antiemetic agent, steroids and Haloperidol, an antidopamine agent.

[A case of left breast cancer resulting in complete response by primary systemic therapy].

The patient was a 39-year-old woman, who noted a mass in her left breast. She was diagnosed with the left breast cancer (T4N2M0, stage IIIB) in our hospital. As primary systemic therapy, she received 4 cycles of FEC 100 every 21 days, and then 4 cycles of paclitaxel (180 mg/m(2)) every 21 days.

Pyogenic liver abscesses secondary to carcinoma of the sigmoid colon: a case report and clinical features of 20 cases in Japan.

We report a case of liver abscesses associated with sigmoid colon cancer in an 81-year-old woman. The patient was referred to our hospital because of a tumorous lesion of the sigmoid colon. Five days before the scheduled operation, she presented abdominal pain, fever and chill.

Emergency operation for phlegmonous gastritis.

Phlegmonous gastritis is a rare inflammatory lesion in which bacterial infection occurs in the gastric wall. A case of phlegmonous gastritis producing an intramural filling defect in the stomach is presented. Endoscopy showed edematous and reddened gastric mucosa with a mass lesion in the gastric body and antrum.
