Observation of crystallisation dynamics by crystal-structure-sensitive room-temperature phosphorescence from Au(I) complexes.

The aggregation behaviour of Au(I) complexes in condensed phases can affect their emission properties. Herein, aggregation-induced room-temperature phosphorescence (RTP) is observed from the crystals of trinuclear Au(I) complexes. The RTP is highly sensitive to the crystal structure, with a slight difference in the alkyl side chains causing not only a change in the crystal structure but also a shift in the RTP maximum.

Highly Efficient Aggregation-Induced Room-Temperature Phosphorescence with Extremely Large Stokes Shift Emitted from Trinuclear Gold(I) Complex Crystals.

Highly efficient (≈75% quantum yield), aggregation-induced phosphorescence is reported. The phosphorescence is emitted at room temperature and in the presence of air from crystals of trinuclear Au(I) complexes, accompanied by an extremely large Stokes shift of 2.2 × 10 cm (450 nm).

Evaluation by dental cone-beam computed tomography of the incidence and sites of branches of the inferior dental canal that supply mandibular third molars.

Our aim was to assess the incidence and anatomical site of branches of the inferior dental canal that supply mandibular third molars using dental cone-beam computed tomography (CT). We evaluated the incidence and diameter of branches of the inferior dental canal using 272 cone-beam CT mandibular scans from 172 patients referred for imaging before the extraction of impacted mandibular third molars. We found three typical branching patterns from the inferior dental canal in the third molar region: the retromolar canal (in the retromolar triangle), the dental canal (that courses directly beneath the socket of the third molar), and the accessory canal (that courses through the socket and leads from the inferior dental canal to a bony ridge).

Cone beam computed tomographic evaluation of nutrient canals and foramina in the anterior region of the mandible.

Purpose: To investigate the incidence and anatomical location of mandibular nutrient canals (NCs) originating from the mandibular canal using dental cone beam computed tomography (CBCT).

Methods: CBCT images from 105 patients were examined to evaluate the presence, number, diameter, and course of NCs.

Results: NCs and their foramina were bilaterally located in 17 (16.

Trabeculotomy ab interno with internal limiting membrane forceps for open-angle glaucoma.

Purpose: To describe a new technique to perform trabeculotomy ab interno on eyes with open-angle glaucoma (OAG).

Methods: This was a retrospective study. We inserted a 25-gauge forceps that is usually used for internal limiting membrane peeling into the anterior chamber, and grasped and pulled the inner wall of Schlemm's canal away from the canal.

Treatment of pterygium by ligation and bevacizumab injection.

Purpose: To describe a technique for treating pterygium by combining a subpterygial injection of bevacizumab followed by pterygial ligation.

Methods: Bevacizumab (1.25 mg/0.

Immediate removal of posteriorly dislocated lens fragments through sclerocorneal incision during cataract surgery.

Aim: To describe a new method of removing dislocated nuclear fragments smaller than one-fourth the size of the lens nucleus through the sclerocorneal incision made for cataract surgery.

Methods: Dislocated lens nuclear fragments on the surface of the retina were removed from six eyes of six consecutive patients. An anterior vitreous cutter with a 27-gauge chandelier endoilluminator (Twinlight illumination) tied to its sleeve was inserted into the eye through the incision made for cataract surgery and used for core vitrectomy.

Human airway submucosal glands augment eosinophil chemotaxis during rhinovirus infection.

Background: Asthma exacerbations are frequently associated with rhinovirus (RV) infections. However, the contribution of airway submucosal gland (SMG) to exacerbations of asthma in RV respiratory infection has not been studied.

Objective: This study was undertaken to examine whether RV-infected human respiratory SMG cells produce pro-inflammatory cytokines and chemokines for eosinophils, and augment eosinophil transmigration across human airway epithelium.

Post-operative adjuvant chemotherapy for colorectal cancer with 5-fluorouracil (5-FU) infusion combined with 1-hexylcarbamoyl-5-fluorouracil (HCFU) oral administration after curative resection.

Background: Although surgical resectability is an important prognostic factor, recurrences are commonly noted in advanced colorectal cancer patients, even after apparently curative surgery. Since such recurrences cannot be cured, better adjuvant chemotherapies are urgently required.

Patients And Methods: We studied the effect of post-operative chemotherapy using oral administration of 1-hexylcarbamoyl-5-fluorouracil (HCFU) with 5-fluorouracil (5-FU) infusion for curatively-resected Stage IIIa and IIIb colorectal cancers.

Randomized controlled trial of 5-fluorouracil (5-FU) infusion combined with 1-hexylcarbamoyl-5-fluorouracil (HCFU) oral administration and HCFU alone as postoperative adjuvant chemotherapy for colorectal cancer.

Background: Although surgical resectability is an important prognostic factor, recurrences are commonly noted in advanced colorectal cancer patients, even after apparently curative surgery. Because such recurrences cannot be cured, better adjuvant chemotherapies are urgently required.

Patients And Methods: We studied the effect of postoperative chemotherapy using 1-hexylcarbamoyl-5-fluorouracil (HCFU) oral administration with or without 5-fluorouracil (5-FU) infusion for curatively resected Stage II and III colorectal cancer.

Prevention of severe premenstrual asthma attacks by leukotriene receptor antagonist.

Background: The etiology and treatment of premenstrual exacerbations of asthma (PMA) remain uncertain.

Objective: We investigated the role of cellular mediators released from inflammatory cells in the airflow limitation during PMA.

Methods: Serum levels of leukotriene (LT) B(4), LTC(4), platelet- activating factor, histamine, IL-1beta, IL-4, IL-5, IL-6, and GM-CSF were measured at different time points, first just before or during menstruation when the peak expiratory flow rate (PEFR) began to decrease precipitously and second during the menstrual midcycle week (days 10-16) when the PEFR returned to baseline values in patients with PMA and in age-matched asthma patients without PMA at the same intervals.

Osteolytic gamma heavy chain disease.

We report a case of gamma heavy chain disease (GHCD) with several unique features: extensive osteolytic lesions simulating advanced multiple myeloma (MM), skin involvement, under the age of 40 yr, and the appearance of a series of pathological cells with indented or lobulated nuclei. The most remarkable feature is a previously unreported extensive bone destruction. Except for the presence of this bone disease, the clinical and pathological features of the patient resembled those of GHCD rather than those of MM.
