Objective: Standard deviation score or Z-score reference charts are used in some countries in preference to percentile charts and are considered as better tools in assessing children with measurements outside the accepted limits of normality. Growth data for Istanbul children have previously been reported as percentiles; hence, the aim of this study is to present these data in Z-score reference tables. Data on secular trend in height in Turkish children will also be presented.
Methods: Height and weight data based on a total of 11 664 height and 11 655 weight measurements in 1100 boys and 1020 girls between 6 and 18 years of age obtained by biannual visits to schools were analyzed. All children came from well-to-do families and were all healthy. All measurements were made by two trained technicians. The LMS method was used in the analyses. The results were expressed as Z-score values for age.
Results: Heights of the boys and girls in all age groups were close to the updated USA growth references and showed an upward trend from previous data on Turkish children.
Conclusions: Height growth in Turkish school-age children of high socioeconomic level conforms to the updated growth data for USA children and also shows a secular trend. The data also point to the importance of updating local growth data periodically.

Reproducibility of fetal ultrasound doppler parameters used for growth assessment.

Objectives: To produce standards of references for quality control and assess the reproducibility of fetal ultrasound Doppler measurements commonly used for blood flow assessment in fetal growth.
Methods: Women with singleton normal pregnancies were prospectively recruited at University College London Hospital, UK, between 24 and 41 weeks. Umbilical artery (UA), middle cerebral artery (MCA), and their pulsatility indices (PI), resistance indices (RI) and ratios such as cerebro-placental (CPR) and umbilical cerebral ratio (UCR) were obtained twice by two sonographers in training or after completion of training, blind to each other's measurements.
Head and Neck Paraganglioma in Pacak-Zhuang Syndrome.

Head and neck paragangliomas (HNPGLs) are typically slow-growing, hormonally inactive tumors of parasympathetic paraganglia. Inactivation of prolyl-hydroxylase domain-containing 2 protein causing indirect gain-of-function of hypoxia-inducible factor-2α (HIF-2α), encoded by EPAS1, was recently shown to cause carotid body hyperplasia. We previously described a syndrome with multiple sympathetic paragangliomas caused by direct gain-of-function variants in EPAS1 (Pacak-Zhuang syndrome, PZS) and developed a corresponding mouse model.

2D template matching (2DTM) can be used to detect molecules and their assemblies in cellular cryo-EM images with high positional and orientational accuracy. While 2DTM successfully detects spherical targets such as large ribosomal subunits, challenges remain in detecting smaller and more aspherical targets in various environments. In this work, a novel 2DTM metric, referred to as the 2DTM p-value, is developed to extend the 2DTM framework to more complex applications.

Department of Pediatrics, Faculty of Medicine, Universiti Malaya, Wilayah Persekutuan Kuala Lumpur, 50603, Kuala Lumpur, Malaysia.
Background: Recently, there has been an increase in the prevalence of childhood obesity in Malaysia, raising concerns about increased cardiometabolic morbidity. MyBFF@school is a multifaceted program comprising physical activity, nutritional education, and psychological empowerment introduced to combat childhood obesity in Malaysia. The efficacy of a six-month intervention on the body composition of overweight and obese primary schoolchildren was evaluated.
