FinnTwin16 : A Longitudinal Study from Age 16 of a Population-Based Finnish Twin Cohort

2019

The purpose of this review is to provide a detailed and updated description of the FinnTwin16 (FT16) study and its future directions. The Finnish Twin Cohort comprises three different cohorts: the Older Twin Cohort established in the 1970s and the FinnTwin12 and FT16 initiated in the 1990s. FT16 was initiated in 1991 to identify the genetic and environmental precursors of alcoholism, but later the scope of the project expanded to studying the determinants of various health-related behaviors and diseases in different stages of life. The main areas addressed are alcohol use and its consequences, smoking, physical activity, overall physical health, eating behaviors and eating disorders, weight…

Data from: Reproductive isolation among allopatric Drosophila montana populations

2014

An outstanding goal in speciation research is to trace the mode and tempo of the evolution of barriers to gene flow. Such research benefits from studying incipient speciation, in which speciation between populations has not yet occurred but where multiple potential mechanisms of reproductive isolation (RI: i.e. premating, postmating-prezygotic (PMPZ), and postzygotic barriers) may act. We used such a system to investigate these barriers among allopatric populations of Drosophila montana. In all heteropopulation crosses we found premating (sexual) isolation which was either symmetric or asymmetric depending on the population pair compared. Postmating isolation was particularly strong in cros…

Diagnosis, phenotype, and prevalence of polycystic ovary syndrome.

2006

New diagnostic criteria for polycystic ovary syndrome (PCOS) suggested three main phenotypes: classic (hyperandrogenism and anovulation), ovulatory, and normoandrogenic. However, it is unclear whether the normoandrogenic phenotype actually represents PCOS. Overall, 6% to 8% of reproductive-aged women suffer from PCOS, making this disorder one of the most common endocrine abnormalities.

Individual alpha peak frequency, an important biomarker for live Z-Score training neurofeedback in adolescents with learning disabilities

2021

Learning disabilities (LDs) have an estimated prevalence between 5% and 9% in the pediatric population and are associated with difficulties in reading, arithmetic, and writing. Previous electroencephalography (EEG) research has reported a lag in alpha-band development in specific LD phenotypes, which seems to offer a possible explanation for differences in EEG maturation. In this study, 40 adolescents aged 10–15 years with LDs underwent 10 sessions of Live Z-Score Training Neurofeedback (LZT-NF) Training to improve their cognition and behavior. Based on the individual alpha peak frequency (i-APF) values from the spectrogram, a group with normal i-APF (ni-APF) and a group with low i-APF (li-…

Personalized medicine in sleep respiratory disorders; focus on OSA diagnosis and treatment.

2017

In all fields of medicine, major efforts are currently dedicated to improve the clinical, physiological and therapeutic understanding of disease, and obstructive sleep apnoea (OSA) is no exception. The personalised medicine approach is relevant for OSA, given its complex pathophysiology and variable clinical presentation, the interactions with comorbid conditions and its possible contribution to poor outcomes. Treatment with continuous positive airway pressure (CPAP) is effective, but CPAP is poorly tolerated or not accepted in a considerable proportion of OSA patients. This review summarises the available studies on the physiological phenotypes of upper airway response to obstruction durin…
