Background: Although several studies have documented the impact of the COVID-19 pandemic on mental health, the long-term effects remain unclear.
Aims: To examine longitudinal changes in mental health before and during the consecutive COVID-19 waves in a well-established probability sample.
Method: An online survey was completed by the participants of the COVID-19 add-on study at four time points: pre-COVID-19 period (2014-2015, = 1823), first COVID-19 wave (April to May 2020, = 788), second COVID-19 wave (August to October 2020, = 532) and third COVID-19 wave (March to April 2021, = 383).
The vertebrate pharynx is a key embryonic structure with crucial importance for the metameric organization of the head and face. The pharynx is primarily built upon progressive formation of paired pharyngeal pouches that typically develop in post-oral (mandibular, hyoid and branchial) domains. However, in the early embryos of non-teleost fishes, we have previously identified pharyngeal pouch-like outpocketings also in the pre-oral domain of the cranial endoderm.

Azoospermia occurs in approximately 1% of the male population, and for an effective therapy of this form of male infertility, it is important to distinguish between obstructive and non-obstructive azoospermia. Proteins in seminal plasma can serve as biomarkers for diagnosing azoospermia.

- - Bone in vertebrates likely originated from ancestral dermal armor, but its developmental origins are debated, especially whether they come from mesoderm or neural crest cells.
- - A study using the sterlet sturgeon shows that neural crest cells from the trunk are responsible for forming osteoblasts in their dermal armor, specifically in scutes.
- - Further analyses indicate that the composition and structure of dermal armor in modern ray-finned fish resemble those of early armored vertebrates, highlighting the neural crest's important evolutionary role in the development of these features across the body.
Even though there is evidence of decreasing trends of per- and polyfluoroalkyl substances (PFAS) in Czechia, there are still major sources of PFAS pollution. Regarding the still-inconsistent results of the relationship between cardiometabolic health and PFAS, the present study sought to determine the association between PFAS levels and the presence of cardiometabolic biomarkers, including blood pressure and dysglycemia drivers in the Czech population. A cross-sectional study with 479 subjects (56.
