Sn-doped BiOCl for photoelectrochemical activities and photocatalytic dye degradation under visible light.

In this work, bismuth oxychloride (BiOCl) and Sn-doped BiOCl (SBCl) with improved visible light photocatalytic activity were synthesized via the co-precipitation method. The XRD analysis determined the tetragonal phase of BiOCl, 1 %, 5 %, and 10 % SBCl. The crystallite sizes were in the range of 20-34 nm.

Objective assessment of nasal resistance among electronic cigarette users.

Background: Electronic cigarettes have been a popular alternative to tobacco smoking. The effect of tobacco smoking on nasal airway resistance has been investigated before; however, the effect of the aerosol generated by electronic cigarettes is still unknown. This study aimed to evaluate the short-term effects of e-cigarettes on nasal airway resistance.

Mandibulotomy: an analysis of its morbidities.

The mandibulotomy is a procedure that was developed to improve access in tumour resection. This study aimed to investigate the complications associated with mandibulotomy and analyze factors that could affect the risks of developing these complications. The hospital records of all patients who underwent a mandibulotomy as part of their tumour ablative surgery at two major centres in Malaysia were reviewed retrospectively.

Anaplastic thyroid carcinoma mimicking thyroid abscess.

Anaplastic thyroid carcinoma (ATC) is a particularly fearsome form of thyroid cancer due to its extreme aggressiveness and dismal prognosis. Patients with ATC typically present with a rapidly enlarging neck mass with compressive symptoms. We report a case of ATC, mimicking a thyroid abscess; in a 52-year-old Chinese male with one month history of enlarging neck mass.

Lidocaine/Phenylephrine Nasal Spray versus Nebulization Prior to Nasoendoscopy: A Randomized Controlled Trial.

Objective To objectively compare the nasal decongestion potency of lidocaine/phenylephrine when delivered with a nasal nebulizer and a nasal spray before a rigid nasoendoscopic examination. Study Design Open-label randomized controlled trial. Setting Multicenter study.
