Models of Classroom Assessment for Course-Based Research Experiences.

Course-based research pedagogy involves positioning students as contributors to authentic research projects as part of an engaging educational experience that promotes their learning and persistence in science. To develop a model for assessing and grading students engaged in this type of learning experience, the assessment aims and practices of a community of experienced course-based research instructors were collected and analyzed. This approach defines four aims of course-based research assessment - 1) Assessing Laboratory Work and Scientific Thinking; 2) Evaluating Mastery of Concepts, Quantitative Thinking and Skills; 3) Appraising Forms of Scientific Communication; and 4) Metacognition of Learning - along with a set of practices for each aim.

Complete Genome Sequences of Cluster A Mycobacteriophages Kenmech and Peterson and Cluster F Mycobacteriophage Rockne.

Kenmech, Peterson, and Rockne are bacteriophages that infect Mycobacterium smegmatis mc 155. Both Kenmech and Peterson genomes are ~52 kbp long and contain 1 tRNA as well as 92 and 89 protein-coding genes, respectively. Rockne has a 56,704-bp genome with 108 protein-coding genes and no tRNA.

Complete Genome Sequence of Cluster C Mycobacteriophage McGee.

Mycobacteriophage McGee is a myovirus isolated from a wet soil sample collected at Manassas, VA, using Mycobacterium smegmatis mc155. McGee has a genome 156,008 bp long, containing 237 protein-coding genes, 31 tRNA genes, and 1 transfer-messenger RNA (tmRNA) gene. McGee shares high gene content similarity to phages in actinobacteriophage cluster C1.

Case Report on Pleural Empyema Thoracis and Urinary Tract Infection Caused by from Lagos, Nigeria.

has been implicated as an important cause of invasive diseases such as septicaemia in neonates and immune-compromised adults with high risk of misdiagnosis, mistreatment, and poor outcomes. Here, we report three new cases of infections in three different hospitalised patients with empyema thoracis (one case) and urinary tract infections (two cases) in a tertiary Hospital in Lagos, Nigeria, and the diagnosis was confirmed with the MALDI-TOF MS instrument. The patients were admitted and treated with parenteral antibiotics (ciprofloxacin, cefotaxime, and ceftriaxone) and discharged after clinical cure.

Malaria Parasitaemia and the use of insecticide-treated nets (INTs) for malaria control amongst under-5 year old children in Calabar, Nigeria.

Background: Malaria remains a major cause of febrile illness in Nigeria and interventions to reduce malaria burden in Nigeria focus on the use of insecticide-treated nets. This study determined the prevalence of malaria parasitaemia and the use of insecticide-treated nets (ITNs) for the control of malaria amongst under-five year old children in Calabar, Nigeria.

Methods: A total of 270 under-5 year old children were recruited and structured questionnaires were used to obtain information on the background characteristics of the respondents from their caregivers.
