Fifty-eight Compylobacter strains were isolated from children with diarrhoea at various health centres in Lagos and from healthy chicken. Twenty-nine strains of Campylobacter were isolated from humans, while the same number were isolated from chicken. The strains were biotyped using the modified Preston biotype scheme. The Preston biotyping results have been compared with the results of Penner ...

BACKGROUND The purpose of this study was to compare phacoemulsification energy parameters during torsional phacoemulsification with or without the use of intelligent phacoemulsification (IP) software. METHODS One hundred and twenty-eight eyes with nuclear grades ranging from 1 to 5 were enrolled in this randomized prospective study. Operated eyes were divided into two groups, ie, those operat...

Regarding the motor end plates, the earliest evidence of the formation of such structures was observed in the muscle of foetuses of nine and ten weeks development. At this stage the developing motor end plate consits of several small axons covered on their outer aspect by Schwann cell cytoplasm, while on the inner aspect they are separated by a layer of basement membrane of the myotube with whi...

OBJECTIVE The development and validation of Modified Disease Activity Scores (DAS) that include different 28-joint counts. METHODS These scores were developed by canonical discriminant analyses and validated for criterion, correlational, and construct validity. The influence of disease duration on the composition of the DAS was also investigated. RESULTS No influence of disease duration was...

This study examines the relationship between facial morphology and nasal respiration. Nasal resistance to expiratory airflow, average volume flow rate, and temporal characteristics of the respiratory cycle were measured for twenty-eight adults. Subjects were categorized as having (1) normal facial proportions with competent lips (n = 10), (2) normal facial proportions with incompetent lips (n =...

I. Calcium balance studies were carried out on twenty-eight apparently normal preschool children who had been for several months on a low Ca intake of zoo mglchild per day. 2. Three-day balances showed that all subjects were in positive balance. The absorption was 50 yo of the intake. 3. When the dietary intake was increased to 280 mg/day there was a greater absorption and retention of Ca. Seru...

BACKGROUND The State of Victoria in Australia introduced Chinese medicine practitioner registration in 2000 and issued its education guidelines in late 2002 for introduction in 2005. This study obtained practitioners' views on desired capabilities for competent Chinese medicine practice and to identify professional development needs. METHODS A questionnaire, consisting of 28 predefined capabi...

In this paper, we have developed a block cipher by using the modular arithmetic inverse of a key matrix. The key matrix is generated by taking the key in the form of twenty-eight numbers, wherein each number is represented in terms of seven binary bits. The encryption is carried out by using the key matrix containing binary bits. The decryption is performed by using the modular arithmetic inver...

One hundred twenty-eight patients were examined prospectively to determine the significance of mucosal thickening seen in the paranasal sinuses during routine MR imaging of the brain. On the basis of responses to a questionnaire, each patient was categorized as symptomatic (n = 60) or asymptomatic (n = 68) for paranasal sinus disease. Patients were categorized further on the basis of the maxima...

This research project was part of a planned initiative at the University of Pittsburgh School of Dental Medicine to incorporate lecture recordings as standard educational support technologies. The goal of an institutional survey was 1) to gather current data about how dental educators across the United States and Canada use lecture recordings; 2) determine dental educators' perceived value and ...
