Introduction: The Alberta Infant Motor Scale (AIMS) is widely used to assess infant motor development but has shown limited cross-cultural validity in various populations. The distribution of the original AIMS scores has not been cross-culturally validated for Norwegian infants. This study aimed to evaluate the applicability of the Canadian AIMS norm reference for Norwegian infants aged 6-9 months and compare their percentile rankings with the Canadian and Dutch norms.

While many chemicals are regulated and routinely monitored in drinking water, they represent just a portion of all contaminants that may be present. Typical drinking water analyses involve sampling one liter or less of water, which could lead to trace level contaminants going undetected. In this study, a method was developed for using point-of-use activated carbon block drinking water filters as sampling devices.

Department of Child and Adolescent Psychiatry, National Institute of Mental Health and Neurosciences, Bangalore, India.
Background: Developmental regression in children, in the absence of neurological damage or trauma, presents a significant diagnostic challenge. The complexity is further compounded when it is associated with psychotic symptoms.
Method: We discuss a case series of ten children aged 6-10 years, with neurotypical development, presenting with late-onset developmental regression (>6 years of age), their clinical course and outcome at 1 year.
Stereoelectronic Effect of Protecting Groups on the Stability of Galactosyl Donor Intermediates.

Department of Chemistry, Hunter College, The City University of New York, 695 Park Ave., New York, NY 10065, USA.
Using methods of DFT, we investigated the effect of electron withdrawing and electron donating groups on the relative stability of tentative glycosyl donor reaction intermediates. The calculation shows that by changing the stereoelectronic properties of the protecting group, we can influence the stability of the dioxolenium type of intermediates by up to 10 kcal mol, and that by increasing nucleophillicity of the 4--Bz group, the dioxolenium intermediate becomes more stable than a triflate-donor pair. We exploited this mechanism to design galactosyl donors with custom protecting groups on O2 and O4, and investigated the outcome of the reaction with cyclohexanol.

Tactical Research Unit, Bond University, Robina, QLD, Australia.
Police tactical group (PTG) officers respond to the most demanding and high-risk police situations. As such, PTG personnel require exceptional physical fitness, and selection for employment often evaluates fitness both directly and indirectly. While heart rate (HR) is often used to measure physical effort, heart rate variability (HRV) may be a valuable tool for measuring stress holistically.
