Burns in the Elderly: Potential Role of Stem Cells.

Burns in the elderly continue to be a challenge despite advances in burn wound care management. Elderly burn patients continue to have poor outcomes compared to the younger population. This is secondary to changes in the quality of the aged skin, leading to impaired wound healing, aggravated immunologic and inflammatory responses, and age-related comorbidities.

Analysis of Long Term Study Indicates Both Agronomic Optimal Plant Density and Increase Maize Yield per Plant Contributed to Yield Gain.

Concurrent to yield, maize (Zea Mays L.) plant density has significantly increased over the years. Unlike yield, however, the rate of change in plant density and its contribution to maize yield gain are rarely reported.

Return-to-work challenges following a work-related mild TBI: The injured worker perspective.

Primary Objective: To explore how individuals with work-related mild traumatic brain injury (wrMTBI) experience return-to-work (RTW) processes when returning to the workplace where the injury occurred.

Design: RTW experiences were explored using in-depth interviews and an inductive analytic approach. Qualitative analysis guided by the research question moved through phases of line-by-line and thematic coding through which categories and the interaction between categories emerged.

Hydrogen sulfide is an endogenous stimulator of angiogenesis.

The goal of the current study was to investigate the role of exogenous and endogenous hydrogen sulfide (H(2)S) on neovascularization and wound healing in vitro and in vivo. Incubation of endothelial cells (ECs) with H(2)S enhanced their angiogenic potential, evidenced by accelerated cell growth, migration, and capillary morphogenesis on Matrigel. Treatment of chicken chorioallantoic membranes (CAMS) with H(2)S increased vascular length.

Identification of Arabidopsis thaliana variants with differential glyphosate responses.

To facilitate future investigations of glyphosate-resistance mechanisms, three approaches were taken to obtain Arabidopsis thaliana variants that differed in glyphosate response. Recurrent selection by spraying with sub-lethal glyphosate concentrations was performed with Columbia-0 seedlings. After seven cycles of treatment, no resistance was found.

Accelerated wound healing by in vivo application of keratinocytes overexpressing KGF.

Epidermal regeneration is a complex process, strongly influenced by growth factors, including keratinocyte growth factor (KGF). The objective of this study was to establish immortalized HaCaT keratinocytes and KMST-6-fibroblasts stably expressing KGF. Transfection efficiency, genomic integration, and functionality of the transgene were determined by ELISA and PCR, and KGF-expressing clones were selected using an air-liquid interface test system.
