TAXON, EarlyView.Abstract We explore phylogenetic relationships within the Pachira sensu lato clade (Bombacoideae, Malvaceae), test the monophyly of the genera Eriotheca and Pachira, and investigate their biogeographic history. The Pachira s.l. clade comprises ca. 72 species that traditionally have been placed in Eriotheca and Pachira. We sampled ca. 79% of its species

Acta Ophthalmologica, EarlyView.Abstract Purpose To examine the presence of secretory autophagy and epithelial–mesenchymal transition (EMT) in the macular retinal pigment epithelium (RPE) of human cadaver eyes with different forms of age‐related macular degeneration (AMD). Methods Human cadaver macula samples representing dry and wet AMD, as well as age‐matched controls, were ...

Modern View of the Sun: Materials for an Experimental History at the Dawn of the Telescopic Era
HistoriesGalileo and the telescope revolutionized the concept of the Sun. The discovery of its rotation was possible due to the continuous observation of the sunspots. The faculae and the maculae with umbra and penumbra became accessible daily to new instruments,

Propagation Properties of Sunspots Umbral Oscillations in Horizontal and Vertical Directions
The Astrophysical Journal, 2023 We present a study on investigating the propagation characteristics of umbral oscillations in sunspots. In sunspot 1 (located in NOAA AR 12127) with four umbrae, the analysis shows that the oscillations in different umbrae are correlated.

Observations key to understanding solar cycles: a review
Frontiers in Astronomy and Space SciencesA paradigm shift is taking place in the conception of solar cycles. In the previous conception, the changing numbers of sunspots over intervals of 9–14 years have been regarded as the fundamental solar cycle although two average 11-year cycles were ...

Short Periodicities in Latitudinal Variation of Sunspots [PDF]
Journal of Astronomy and Space Sciences, 2011 The latitudinal variation of sunspots appearing during the period from 1874 to 2009 has been studied in terms of centerof- latitude (COL). The butterfly diagram has been used to study the evolution of the magnetic field and the dynamics at the bottom ...

Single oral administration of dronabinol increases ocular blood flow in patients with glaucoma
Acta Ophthalmologica, EarlyView.Abstract Purpose Glaucoma is a leading cause of irreversible blindness globally, primarily driven by elevated intraocular pressure (IOP). Still, some patients progress despite significant IOP lowering, potentially due to impaired ocular blood flow. This study aimed to evaluate the effects of dronabinol, a synthetic tetrahydrocannabinol derivative, on ...

Journal of Environmental Engineering and Landscape Management, 2015 The connection has been found between the course of cardiovascular diseases (CVD) and the hard cosmic ray flux (HCRF) near the ground surface in Vilnius. The course of air temperature and number of sunspot was simultaneously considered. The investigation
