Phosphoric Acid-Mediated Regeneration Of Sugarcane Bagasse Cellulose-Rich Fraction For Enzymatic Production Of Water-Soluble Cellulosic Oligomers, Chiou-Yeong Saw, David Agus Setiawan Wibisono, Tsung-Yen Wu, Yung Chang, Chi-Fai Chau
Journal of Food and Drug Analysis
An integrated strategy was developed to promote conversion of a sugarcane bagasse cellulose-rich fraction into water-soluble cellulosic oligomers (WCOs) through phosphoric acid-mediated regeneration and enzymatic hydrolysis. Alkaline pretreatment on sugarcane bagasse powder increased glucan content from 57.6 to 93.4 g/100 g sample and lowered Klason lignin to 6.1 g/100 g sample. Phosphoric acid-mediated regeneration was subsequently capable of reorganizing the structure of cellulose from sugarcane bagasse, resulting in a decrease of crystallinity from 72.9 to 64.0% and introducing cellulose II-like features. The hydration state of regenerated cellulose strongly influenced hydrolysis performance, as the hydrated form showed significantly higher solubilization (810.4 …

Temporary Cattle Identification: Benefits Of Marking With Hair Bleach, Melanie Heaton, Reganne K. Briggs, Rebekah Iverson, Brooke Holgate, David Secrist
All Current Publications
Temporary identification is an important management tool for beef producers. Animals are routinely marked following breeding, pregnancy diagnosis, vaccination, treatment, sorting, shipping, and marketing so they can be quickly identified without repeated handling. Effective temporary identification improves labor efficiency, reduces animal stress, and helps ensure management decisions are applied to the correct animals. This fact sheet provides information on temporary cattle marking using hair bleach.
Aspen Health On Cedar Mountain: What Landowners Should Know, Justin Derose, Darren Mcavoy
Aspen Health On Cedar Mountain: What Landowners Should Know, Justin Derose, Darren Mcavoy
All Current Publications
Aspen forests are among the most valuable parts of the Cedar Mountain area in southwest Utah and of Utah's landscapes. They provide wildlife habitat, improve scenery, help slow wildfire spread, and support healthy watersheds and grazing lands. Cedar Mountain’s aspen forests are changing. The landscape still supports significant aspen acreage, but many stands are aging and losing mature trees faster than they are being replaced. Researchers studied the area to assess the health of the aspen forest over many years, beginning in 2008; this fact sheet discusses the results. It also provides management considerations.

Comparative Analysis Of Bacterial Recbcd And Sbcc-Sbcd Systems And The Yeast Mre11-Rad50 Complex During Dna Replication, Tannos Seyedjavadi
Dissertations and Theses
Accurate completion of DNA replication when forks converge is essential for genome stability. In Escherichia coli, several proteins have been identified including RecG, ExoI, RecBCD, and SbcCD, that contribute to completing replication, and loss of these factors causes genetic instability. Eukaryotes encode proteins with homology to several E. coli completion enzymes. Mre11–Rad50 complex is structurally and functionally conserved with bacterial SbcCD, and Rrm3 shares homologous motifs with bacterial RecBCD. These proteins are often described as being involved in homologous double strand break repair. Whether they are also conserved and play a similar role as their E. coli counterparts in …

From Data To Medicine: A Milestone For Medical Chemistry And Bioinformatics In Indonesia, Fadilah Fadilah
Indonesian Journal of Medical Chemistry and Bioinformatics
Biomedical science is rapidly moving from data generation toward data-driven discovery and clinical translation. Genomics, epigenomics, transcriptomics, proteomics, metabolomics, and microbiomics now provide multiple perspectives on human biology, while bioinformatics, artificial intelligence, and molecular modelling enable these complex datasets to be interpreted. The challenge is no longer simply to generate data, but to transform data into knowledge and knowledge into better medicine. This transition is particularly important for Indonesia, where genetic, environmental, microbial, and biological diversity creates both a challenge and an opportunity for population-relevant biomedical research.
