Sequence of Chemotherapy May Not Impact Survival After Resection of Pancreatic Tail Adenocarcinoma.

Introduction: Pancreatic ductal adenocarcinoma (PDAC) of the body/tail is notably different than PDAC in the head of the pancreas. Surgery plus chemotherapy is known to improve outcomes for all PDAC. The sequence of this therapy is well studied in head cancers yet has never been evaluated systematically in relation to distal pancreatectomy (DP).

Work Systems Factors Associated With Burnout in Sonographers Working in the United States and Canada.

Objective: Burnout in sonographers is a prevalent and complex professional hazard associated with poorer quality of work life, productivity, and patient outcomes. This study aimed to understand the prevalence of and work systems factors associated with burnout among a large sample of sonographers.

Materials And Methods: Research study registry participants (n=3659) were invited to complete a follow-up survey about personal and work environment factors, including work hours, break time, coworker and supervisor support, and job satisfaction, overall health, and sleep quality.

Outcomes of Hematopoietic Stem Cell Transplantation in 5 Patients with Autosomal Recessive RIPK1-Deficiency.

Receptor Interacting Serine/Threonine Kinase 1 (RIPK1) is widely expressed and integral to inflammatory and cell death responses. Autosomal recessive RIPK1-deficiency, due to biallelic loss of function mutations in RIPK1, is a rare inborn error of immunity (IEI) resulting in uncontrolled necroptosis, apoptosis and inflammation. Although hematopoietic stem cell transplantation (HSCT) has been suggested as a potential curative therapy, the extent to which disease may be driven by extra-hematopoietic effects of RIPK1-deficiency, which are non-amenable to HSCT, is not clear.

Octahedral small virus-like particles of dengue virus type 2.

Unlabelled: Flavivirus envelope (E) and precursor M (prM) proteins, when ectopically expressed, assemble into empty, virus-like particles (VLPs). Cleavage of prM to M and loss of the pr fragment converts the VLPs from immature to mature particles, mimicking a similar maturation of authentic virions. Most of the VLPs obtained by prM-E expression are smaller than virions; early, low-resolution cryo-EM studies suggested a simple, 60-subunit, icosahedral organization.
