The Role of Salicylic Acid in Salinity Stress Mitigation in : A Medicinal Species Native to South America.

Salicylic acid (SA) is a bioregulator well-known for mitigating salinity damage in plants. However, no studies have examined the interaction between SA and salinity in , a species rich in bioactive molecules. Therefore, we aimed to evaluate the effect of SA application on under different salinity levels.

In Vitro Propagation of "Salsaparrilha" [Herreria salsaparrilha Mart. (Asparagaceae)]: An Antisyphilitic Medicinal Species.

An efficient procedure for in vitro propagation of Herreria salsaparrilha Martius was established from single-node explants (fourth and fifth nodes from apex to the base) derived from donor plants maintained under shading-house conditions. After surface sterilization, explants are inoculated in test tubes containing 15 mL of Murashige and Skoog (MS) medium without growth regulators. Cultures are maintained under 35 μmol m s irradiance, a 16/8-h light/dark light regime, at 26 ± 2 °C.

Impact of COVID-19 pandemic on mobility of older adults: A scoping review.

Aims And Objectives: To identify the most frequent determinants of contact limitation on older adults' mobility addressed by the recommendations to mitigate mobility limitation during the COVID-19 pandemic and identify the recommendations characteristics and means of dissemination that might guide coping actions.

Background: Measures for physical contact restriction were implemented to prevent COVID-19 spread. These measures directly impacted older people, reducing their mobility, especially outside home environment.

Physiological, epigenetic, and proteomic responses in Pfaffia glomerata growth in vitro under salt stress and 5-azacytidine.

Plants adjust their complex molecular, biochemical, and metabolic processes to overcome salt stress. Here, we investigated the proteomic and epigenetic alterations involved in the morphophysiological responses of Pfaffia glomerata, a medicinal plant, to salt stress and the demethylating agent 5-azacytidine (5-azaC). Moreover, we investigated how these changes affected the biosynthesis of 20-hydroxyecdysone (20-E), a pharmacologically important specialized metabolite.

ABO blood group and link to COVID-19: A comprehensive review of the reported associations and their possible underlying mechanisms.

ABO blood group is long known to be an influencing factor for the susceptibility to infectious diseases, and many studies have been describing associations between ABO blood types and COVID-19 infection and severity, with conflicting findings. This narrative review aims to summarize the literature regarding associations between the ABO blood group and COVID-19. Blood type O is mostly associated with lower rates of SARS-CoV-2 infection, while blood type A is frequently described as a risk factor.
