Improving scientific reasoning enables students to navigate the challenges of learning science. Teachers use Lawson's classroom test of scientific reasoning (LCTSR) to measure scientific reasoning. The LCTSR is a two-tiered assessment that uses content-based questions and explanation statements.

- The study examined the brain structure, blood vessels, and cognitive abilities of 19 late-onset Pompe disease patients, comparing them to classic infantile cases where severe cognitive issues and brain abnormalities are common.
- Using various brain imaging techniques and cognitive assessments, most late-onset patients displayed normal cognitive functioning and only mild microvascular lesions were found, which are considered normal for their age.
- The results indicate significant differences between late-onset and classic infantile Pompe disease patients, with the former showing no major brain abnormalities or cognitive impairments.
The Social Norms Questionnaire-Dutch version (SNQ-NL) measures the ability to understand and identify social boundaries. We examined the psychometric characteristics of the SNQ-NL and its ability to differentiate between patients with behavioral variant frontotemporal dementia (bvFTD; = 23), Alzheimer's dementia (AD; = 26), chronic psychiatric disorders ( = 27), and control participants ( = 92). Between-group differences in the Total score, Break errors, and Overadhere errors were examined and associations with demographic variables and other cognitive functions were explored.

Sexually active, HIV-negative women, aged 16-22 years recruited from Soweto (n = 143) and Cape Town (n = 148) were tested for cervical HPV and other genital infections. Overall HPV prevalence was 66.

Method Of Study: We compared HIV RNA levels between MC, endocervical swab (ECS), and ECS-enriched cervicovaginal lavage (eCVL) specimens in 51 HIV-positive, antiretroviral therapy-naive women at enrollment, 3 and 6 months, with order rotated by visit. Paired comparisons were analyzed with McNemar's exact tests, signed-rank tests, and an extension of Somer's D for pooled analyses across visits.
Results: MC specimens had the highest proportion of quantifiable HIV VL at enrollment and month 3, but more MC specimens (n=12.
