Glycolic acid is an attractive raw material which is used as a dyeing and tanning agent in the textile industry, a flavoring agent and preservative in the food processing industry, and a skin care agent in the pharmaceutical industry. It is also utilized for the production of polyglycolic acid and other biocompatible copolymers. Glycolic acid can be isolated from natural sources, such as sugarc...

Irritable bowel syndrome (IBS) in the outpatient with chronic inflammatory bowel disease (IBD) is a difficult but important challenge to recognize and treat. It is very helpful to have effective treatment approaches for IBS that are practical and use minimal medications. Because of the underlying chronic inflammation in IBD, IBS symptoms occur with increased frequency and severity, secondary to...

We studied the effect of precooling and the use of an ethylene absorbent (based on potassium permanganate) in the flower boxes, on the vase life of Dendrobium ‘Pompadour’ flowers, after simulation of air shipment (3 days at 25°C). Precooling at 10°C (85-95%RH) for 60 minutes reduced ethylene production, ACC activity, and the concentration of 1-aminocyclopropane-1-carboxylic acid (ACC) in the fl...

The aim of the study was to isolate Salmonella from fresh cabbage and spinach vegetables, determine antimicrobial resistance and biofilm formation of the isolates. Spinach and cabbage farm vegetables were found to harbour Salmonella. A total of eighty-two Salmonella isolates were recovered from both vegetables and subjected to antimicrobial reactions. Salmonella isolate showed sensitivity again...

Lindane is losing much of any luster it once had. The pesticide, once widely used to kill lice and a variety of pests that attack agricultural products, livestock, and trees, has slowly been eliminated from many applications since the mid-1970s. As long ago as the early 1980s, three U.S. organizations petitioned the U.S. Food and Drug Administration (FDA) to ban lindane following an FDA doctor’...

A rapid method for detection of Escherichia coli O157: H7 using multiplex PCR was developed. Two oligonucleotide primer pairs were used for simultaneously detection of vt encoding verotoxin genes for virulence factor and rfbO157 encoding the O-antigen specific for E. coli O157: H7. Multiplex PCR generated two products of 215 bp and 420 bp for vt and rfbO157, respectively. Multiplex PCR detected...

Ali, A., Mohammad, O., and Khattab, A. 2012. Distribution of viruses infecting cucurbit crops and isolation of potential new virus-like sequences from weeds in Oklahoma. Plant Dis. 96:243-248. Field surveys were conducted from 2008 to 2010 to detect and determine the incidence of viruses in the major cucurbit-growing areas of Oklahoma. In total, 1,049 symptomatic leaf samples (890 from cucurbit...

A comparative study was initiated to determine if habitat influences the abundance and richness of nitidulid beetle fauna at three sites (Kent Bog, Tinkers Creek, and Gott Fen) managed by the Division of Natural Areas and Preserves of the Ohio Department of Natural Resources. These sites in Portage County were sampled from early May through late October of 1990. Six sampling techniques were use...

The theory-based model of categorization posits that concepts are represented as theories rather than as feature lists. Thus, it is particularly interesting that the DSM-IV (American Psychiatric Association, 1994), establishes a set of atheoretical guidelines for diagnosis in the domain of mental disorders. Five experiments investigated how clinicians handle an atheoretical nosology. Clinical p...
