Moving Toward a Cure for Myeloma.

Am Soc Clin Oncol Educ Book 2022 Apr;42:1-12

Department of Medicine, Division of Hematology-Oncology, David Geffen School of Medicine at UCLA, Los Angeles, CA.

Historically, multiple myeloma has been considered an incurable disease, mainly because of its recurrence after transient control. However, the landscape of multiple myeloma therapeutics has significantly changed over the last 2 decades, with disease remissions lasting much longer. The advent of modern-day induction regimens, usage of high-dose melphalan followed by autologous stem cell transplantation, and well-tolerated maintenance regimens has resulted in deeper and durable responses, with less frequent disease recurrences, and patients are living much longer.

Medical Therapies for Heart Failure in Hypoplastic Left Heart Syndrome.

J Cardiovasc Dev Dis 2022 May 12;9(5). Epub 2022 May 12.

Department of Pediatrics, Section of Cardiology, University of Colorado Anschutz Medical Campus, Children's Hospital Colorado, Aurora, CO 80045, USA.

Significant surgical and medical advances over the past several decades have resulted in a growing number of infants and children surviving with hypoplastic left heart syndrome (HLHS) and other congenital heart defects associated with a single systemic right ventricle (RV). However, cardiac dysfunction and ultimately heart failure (HF) remain the most common cause of death and indication for transplantation in this population. Moreover, while early recognition and treatment of single ventricle-related complications are essential to improving outcomes, there are no proven therapeutic strategies for single systemic RV HF in the pediatric population.

Poly(N-Isopropylacrylamide) Based Electrically Conductive Hydrogels and Their Applications.

Gels 2022 May 1;8(5). Epub 2022 May 1.

Department of Orthopedic Surgery, The First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China.

Poly(N-isopropylacrylamide) (PNIPAM) based electrically conductive hydrogels (PNIPAM-ECHs) have been extensively studied in recent decades due to their thermal-responsive (leading to the volume change of hydrogels) and electrically conductive performance. The incorporation of conductive components into the PNIPAM hydrogel network makes it become conductive hydrogel, and as a result, the PNIPAM hydrogel could become sensitive to an electrical signal, greatly expanding its application. In addition, conductive components usually bring new stimuli-responsive properties of PNIPAM-based hydrogels, such as near-infrared light and stress/strain responsive properties. Read More

In Situ Growth of Zeolitic Imidazolate Framework-L in Macroporous PVA/CMC/PEG Composite Hydrogels with Synergistic Antibacterial and Rapid Hemostatic Functions for Wound Dressing.

Gels 2022 May 1;8(5). Epub 2022 May 1.

College of Materials and Metallurgy, Guizhou University, Guiyang 550025, China.

Although many advances have been made in medicine, traumatic bleeding and wound infection are two of the most serious threats to human health. To achieve rapid hemostasis and prevent infection by pathogenic microbes, the development of new hemostatic and antibacterial materials has recently gained significant attention. In this paper, safe, non-toxic, and biocompatible polyvinyl alcohol (PVA); carboxymethyl cellulose (CMC), which contains several carboxyl and hydroxyl groups; and polyethylene glycol (PEG), which functions as a pore-forming agent, were used to prepare a novel PVA/CMC/PEG-based composite hydrogel with a macroporous structure by the freeze-thaw method and the phase separation technique.

Eukaryotic tRNA splicing - one goal, two strategies, many players.

Biol Chem 2022 May 30. Epub 2022 May 30.

Biochemistry Center (BZH), Heidelberg University, D-69120 Heidelberg, Germany.

Transfer RNAs (tRNAs) are transcribed as precursor molecules that undergo several maturation steps before becoming functional for protein synthesis. One such processing mechanism is the enzyme-catalysed splicing of intron-containing pre-tRNAs. Eukaryotic tRNA splicing is an essential process since intron-containing tRNAs cannot fulfil their canonical function at the ribosome. Read More
