TRAF2/3 deficient B cells resist DNA damage-induced apoptosis via NF-κB2/XIAP/cIAP2 axis and IAP antagonist sensitizes mutant lymphomas to chemotherapeutic drugs.

Deletion of TRAF2 or TRAF3 in B cells prolongs their survival. However, it remains unknown whether deletion of such factors affects B cells' ability to tolerate DNA damage, which can be induced by chemotherapeutics and cause apoptosis. Genetic alterations of TRAF2 or TRAF3 are observed in subsets of human B-cell lymphomas and B cell-specific deletion of TRAF3 led to lymphoma development in aged mice.

A Novel Do-It-Yourself Approach to Simulating Minimally Invasive Laparoscopic Surgery.

In 2008, the American Board of Surgery required residents to pass a laparoscopic fundamentals examination to sit for the boards. As such, minimally invasive surgery became the newest addition as a requisite skill for surgical trainees. To assist in preparing trainees for future surgery, simulation devices have been integrated into training programs to develop proficiency with laparoscopic and arthroscopic techniques.

Telemedicine Intensive Care Unit (Tele-ICU) Implementation During COVID-19: A Scoping Review.

Telemedicine intensive care unit (Tele-ICU) programs entail command centers staffed with intensivists and critical care nurses who electronically aid with and deliver real-time information to frontline clinicians. The benefits of Tele-ICU are numerous, but the barriers to it often prove insurmountable, accounting for slow adoption in rural and underserved areas where it is needed the most. Remote monitoring can quickly detect patient deterioration, while consultation provided by a remote intensivist expands the capabilities of smaller facilities.

Amide additives improve RDC measurements in polyacrylamide.

Residual dipolar couplings (RDCs) provide valuable NMR parameters that can be used for structural calculation and verification. Measuring RDCs requires aligning macromolecules using one of various types of alignment media. Of different alignment media options, stretched or compressed polyacrylamide gels are advantageous due to their chemical stability.

1-Thioglycerol: inhibitor of glycerol kinase activity in vitro and in situ.

The infantile form of glycerol kinase (GK) deficiency (McKusick No. 30703) (1) is characterized by adrenal cortical insufficiency, adrenal hypoplasia and developmental delay. The underlying biochemical mechanism(s) responsible for the observed clinical presentations are undetermined.
