The 18S rRNA Methyltransferase DIMT-1 Regulates Lifespan in the Germline Later in Life.

Ribosome heterogeneity has emerged as an important regulatory control feature for determining which proteins are synthesized, however, the influence of age on ribosome heterogeneity is not fully understood. Whether mRNA transcripts are selectively translated in young versus old cells and whether dysregulation of this process drives organismal aging is unknown. Here we examined the role of ribosomal RNA (rRNA) methylation in maintaining appropriate translation as organisms age.

Surgical Reconstruction of Stage 3 and 4 Pressure Injuries: A Literature Review and Proposed Algorithm from an Interprofessional Working Group.

Objective: Stage 3 and 4 pressure injuries (PIs) present an enormous societal burden with no clearly defined interventions for surgical reconstruction. The authors sought to assess, via literature review and a reflection/evaluation of their own clinical practice experience (where applicable), the current limitations to the surgical intervention of stage 3 or 4 PIs and propose an algorithm for surgical reconstruction.

Methods: An interprofessional working group convened to review and assess the scientific literature and propose an algorithm for clinical practice.

Analysis of births, abortions and maternal mortality in adolescents in Ecuador from 2013 to 2016.

Introduction: Adolescent pregnancy is associated to school desertion, violence, termination of pregnancy under suboptimal conditions, obstetric complications and other consequences that can put the woman's quality of life at risk and of those that surround her. The purpose of this study is to describe the situation and tendencies of adolescent pregnancies, abortions and maternal deaths between 2013 and 2016 in Ecuador.

Methods: This cross-sectional study uses secondary data from national Ecuadorian vital statistics reports of adolescents between 10 and 19 years old.

Efficient Enzyme-Free Biomimetic Sensors for Natural Phenol Detection.

The development of sensors and biosensors based on copper enzymes and/or copper oxides for phenol sensing is disclosed in this work. The electrochemical properties were studied by cyclic and differential pulse voltammetry using standard solutions of potassium ferrocyanide, phosphate/acetate buffers and representative natural phenols in a wide pH range (3.0 to 9.

Inside look at laparoscopic colectomy.

Laparoscopic colectomy has developed into a viable alternative to colon surgery. This paper presents an overview of the development and current status of laparoscopic surgery of the colon with a brief review of the evidence of efficacy of laparoscopic surgery in cancer management. The experience with laparoscopic surgery of the colon at a tertiary hospital in Puerto Rico is discussed with review of 142 consecutive cases treated for diverticulosis, cancer or polyps performed from 2005-2010.
