Lysis by KOH and hydrolysis of L-alanine-4-nitroanilide were compared with the Gram reaction of aerobic, microaerophilic, and anaerobic bacteria. Both tests correlated well with the Gram reaction with nonfermentative bacilli and Bacillus species, whereas they did not correlate with nonsporulating anaerobes. Only campylobacteria were KOH positive and L-alanine-4-nitroanilide and gram negative.

In present work, we demonstrate a simple but effective strategy for high-performance supercapacitors by adding the p-nitroaniline (PNA) into an alkaline electrolyte of KOH. PNA possesses a unique molecular structure with the functional groups of -NH2 and -NO2. Besides, both the product of nitro-reduction (-NH2) and intrinsic -NH2 on the benzene ring can lead to the occurrence of Faradaic redox ...

The OH-initiated reaction rate constants (kOH) are of great importance to measure atmospheric behaviors of polychlorinated dibenzo-p-dioxins (PCDDs) in the environment. The rate constants of 75 PCDDs with the OH radical at 298.15 K have been calculated using high level molecular orbital theory, and the rate constants (kα, kβ, kγ and kOH) were further analyzed by the quantitative structure-activ...

BACKGROUND Molluscum contagiosum is one of the commonest cutaneous viral infections in children. All treatment modalities are associated with substantial pain, tissue destruction, and frequent recurrence. OBJECTIVES To compare the efficacy and side effects of KOH 5% solution with tretinoin 0.05% cream for the treatment of molluscum contagiosum in children. METHODS Fifty patients were random...

CMK-8, a mesoporous carbon material, was activated using different methods for the adsorption of low-concentration airborne formaldehyde. KOH and ammonia treatments were used to activate CMK-8. A CMK-8 sample was treated with KOH first followed by an ammonia-treatment at 700 degrees C to determine the effect of a combination of the two treatment methods. The adsorbents prepared were characteriz...

BACKGROUND The diagnosis of Candida vulvovaginitis using historical symptoms, pelvic examination findings, and results of traditional in-office laboratory tests is often inaccurate. Although Candida cultures can verify the diagnosis, they are not routinely used. METHODS We prospectively compared the accuracy of a commercially available, in-office, rapid, latex agglutination test (CandidaSure)...

Introduction: The clinical pictures of nail dystrophies caused by different fungi are seldom diagnostic. Mycological confirmation with appropriate diagnostic techniques including direct microscopy and fungal culture is important to ensure correct diagnosis and treatment. Microscopy can be performed using potassium hydroxide (KOH) mount and histological evaluation of nail plate specimens with th...

The Gulf Journal of Dermatology and Venereology ABSTRACT Pityriasis versicolor (PV), a mycotic infection, is characterized by discrete or concrescent, scaly, discolored or hypopigmented areas. The clinical presentation, though very typical, may be confused with other skin disorders. This study was aimed to evaluate the reliability of cellophane tape as a method for diagnosis of PV versus the st...

BACKGROUND Onychomycosis is a common problem noticed in clinical practice. Currently available standard laboratory methods show inconsistent sensitivity; hence there is a need for newer methods of detection. AIMS This study involves comparison of standard laboratory tests in the diagnosis of onychomycosis, namely, potassium hydroxide mount (KOH mount) and mycological culture, with histopathol...

Koh and Tan gave a sufficient condition for a 3-partite tournament to have at least one 3-king in [K.M. Koh, B.P. Tan, Kings in multipartite tournaments, Discrete Math. 147 (1995) 171–183, Theorem 2]. In Theorem 1 of this paper, we extend this result to n-partite tournaments, where n 3. In [K.M. Koh, B.P. Tan, Number of 4-kings in bipartite tournaments with no 3-kings, Discrete Math. 154 (1996)...
