Cross-Generational Understandings of Ageism and Its Perceived Impacts on Personal-Public Health.

In 2016, the World Health Organization (WHO) launched a global campaign to combat ageism, emphasizing its potential harm to personal and public health. This qualitative focus group study explored generational differences in understanding the WHO's definition and impact of ageism among baby boomers (ages 60-72; n = 17) and silent generation members (ages 78-85; n = 10). Verbatim transcripts were analyzed via a grounded theory approach, and representative themes and quotations were extracted by consensus.

Biodegradable Polymeric Foams Based on Modified Castor Oil, Styrene, and Isobornyl Methacrylate.

The environmental issues of petroleum-derived polymeric foams have necessitated seeking renewable alternatives. This work aims to prepare renewable free-radically polymerized polymeric foams with the ability to biodegrade. Furthermore, this work attempted to incorporate a bio-based reactive diluent, which has not been reported in the literature.

Organic chemical devulcanization of rubber vulcanizates in supercritical carbon dioxide and associated less eco-unfriendly approaches: A review.

There is a growing need to recover raw materials from waste due to increasing environmental concerns and the widely adopted transition to circular economy. For waste tyres, it is necessary to continuously develop methods and processes that can devulcanize rubber vulcanizates into rubber products with qualities and properties that can closely match those of the virgin rubber. Currently, the most common, due to its efficiency and perceived eco-friendliness in recovering raw rubber from waste rubbers, such as tyres, is devulcanization in supercritical carbon dioxide (scCO) using commercial and typical devulcanizing agents.

The Extracellular Domain of Pollen Receptor Kinase 3 is structurally similar to the SERK family of co-receptors.

During reproduction in flowering plants, the male gametophyte delivers an immotile male gamete to the female gametophyte in the pistil by formation of pollen tubes. In Arabidopsis thaliana, two synergid cells situated on either side of the egg cell produce cysteine-rich chemoattractant peptide LURE that guides the pollen tube to the female gametophyte for sexual reproduction. Recently, in Arabidopsis thaliana, Pollen Receptor Kinase 3 (PRK3), along with PRK1, PRK6, and PRK8, have been predicted to be the receptors responsible for sensing LURE.

Infection control practices in assisted living facilities: a response to hepatitis B virus infection outbreaks.

Background: The medical needs of the approximately 1 million persons residing in assisted living facilities (ALFs) continually become more demanding. Moreover, the number of ALF residents is expected to double by 2030. ALFs are not subject to federal oversight; state regulations that govern ALF infection control are variable.
