The Impact of Light Physical Activity, Sedentary Behavior and Cardiorespiratory Fitness in Extending Lifespan and Healthspan Outcomes: How Little is Still Significant? A Narrative Review.

To describe the relationship between mortality and measures of low intensity physical activity (LIPA) as well as sedentary behavior (SB), and cardiorespiratory fitness (CRF). Study selection was performed through multiple database searches from January 1, 2000 until May 1, 2023. Seven LIPA studies, 9 SB studies, and 8 studies CRF studies were selected for primary analysis.

Review of the fossil record of Bolitophilidae, with description of new taxa and discussion of position of Mangas Kovalev (Diptera: Sciaroidea).

The dipteran family Bolitophilidae, with the single extant genus Bolitophila, is a small family of mycophagous flies. In marked contrast to related families such as Sciaridae and Mycetophilidae, the family has a poor fossil record with no definite species assigned to the genus. In addition, the position of the extinct Cretaceous subfamily Mangasinae Kovalev, 1986 (described in Bolitophillidae) has been controversial and it has been suggested that species in this clade may belong to other sciaroid families.
