Global trends of dalbavancin: A bibliometric analysis.
(Wiley, 2022) Monteagudo Martínez, Nuria; Solís García del Pozo, Julián; Ikuta, Ichiro; Galindo Anaya, María Francisca; Jordán Bueso, Joaquín
What is known and objective?: Dalbavancin is used against gram-positive pathogens such as Staphylococcus aureus in acute bacterial skin and skin-structure infections. Methods: Our main goal was to identify the key articles sustaining the current knowledge of this drug's therapeutic possibilities through a bibliometric analysis of the available literature.

An environmentally friendly production of ester-biolubricant from oleic acid.
(Wiley, 2022) Ramos Mellado, Francisco Javier; Haro, Juan Carlos de; Rodríguez Romero, Juan Francisco; Pérez Martínez, Ángel; Carmona Delgado, Manuel
The production of oleic-based trimethylolpropane (TMP) esters via the esterification reaction between oleic acid (OA) and TMP in a reactive distillation system, employing the environmentally friendly catalyst methanesulfonic acid, was explored. The homogeneous acid catalyst, the OA/TMP molar ratio within 1.0–3.0, the esterification reaction enhancement and a new purification technique, using choline hydroxide (ChOH), for obtaining choline carboxylate as a subproduct, were studied.

Evaluating Guayule (Parthenium argentatum A. Gray) Germplasm Grown in Spain: Rubber and Resin along Three Production Cycles
(MDPI, 2024) Jara García, Francisco Miguel; García Martínez, María de las Mercedes; López Córcoles, Horacio; Carrión Jiménez, María Engracia; Zalacain Aramburu, Amaya; Carmona Delgado, Manuel
Rubber and resin are potentially important products of guayule (Parthenium argentatum A. Gray) that can assure the profitability of this crop as an agricultural alternative for the semi-arid areas of central and eastern Spain. This study analyzes, for the first time, the changes in rubber and resin production across 27 guayule accessions (traditional and modern) and along three cycles under the agroclimatic conditions of Castilla-La Mancha, simulating industrial management with a biannual
harvest. The rubber content (% of dry mass) increased from 4.2% in one-year-old plants to 6.6% in twoyear-old plants, but decreased after harvesting. Contrastingly, the rubber yield doubled in contiguous sampling, reaching a mean of 303.6 kg ha-1, with a maximum yield of 341.2 kg ha-1 after the first harvest. Three patterns of rubber production were established based on the production periods. A similar analysis was performed for resin production, which was heterogeneous across accessions
belonging to the same rubber groups. In this case, three independent groups were established to classify the resin accumulation profiles following the same criteria of production periods. Here, we demonstrate that biannual harvesting has the potential to enhance rubber accumulation in summer, although more research is needed for its adaption to current harvesting techniques in this area

Profile and accumulation of essential oils from guayule (Parthenium argentatum A. Gray) accessions and hybrids
(Elsevier, 2024) García Martínez, María de las Mercedes; Saúl Esteban, Luis; Mediavilla, Irene; Carrión Jiménez, María Engracia; González Navarro, Emilio José; Carmona Delgado, Manuel; Zalacain Aramburu, Amaya
For guayule (Parthenium argentatum A. Gray) to become a viable market option, it will be necessary to exploit not only the rubber and resin components, but also other high-value plant products such as essential oils (EOs). A detailed EO profiling study was conducted on 16 guayule accessions for first time, which revealed significant differences in EO yield and profile among them. Accession AZ-2 had the highest yield up to 0.9% (dry weight), followed by CFS18–2005, CAL-7, and CFS17–2005. These yields were comparable with those of aromatic plants used in the industry, providing valuable economic insights. The volatile EO composition of the accessions was unique and discriminating. Volatile sesquiterpenes were the most abundant compounds at the beginning of the flowering stage (S1-June sampling), while monoterpenes became more abundant as flowering progressed (S2-July and S3-August sampling). At S1, it was possible to distinguish between hybrid (mariola and non-mariola) and other accessions by the EO profile. By the end of the summer season (S3, August 2023), the EO volatile profile could more easily distinguish the accessions according to their genetic origin, enabling the separation of pure guayule accessions. The extraction of guayule EOs on an industrial scale (1.2 Mg fresh biomass) demonstrated high yield and consistency in terms of volatile profile, underscoring its potential for commercial exploitation.
