BRCA1 deficiency is observed in approximately 25% of triple-negative breast cancer (TNBC). BRCA1, a key player of homologous recombination (HR) repair, is also involved in stalled DNA replication fork protection and repair. Here, we investigated the sensitivity of BRCA1-deficient TNBC models to the frequently used replication chain terminator gemcitabine, which does not directly induce DNA breaks.

Hemolytic anemia (HA) is characterized by massive destruction of red blood cells (RBCs) and insufficient oxygen supply, which can lead to shock, organ failure, even death. Recent studies have preliminarily demonstrated the therapeutic effectiveness of whole blood exchange (WBE) in the management of acute hemolytic anemia and exhibited potential for reducing the duration of corticosteroid treatment, while the underlying mechanism of WBE therapy was not investigated in preclinical study. Hence, we investigate the therapeutic mechanisms of WBE in HA through established continued WBE therapy in rats creatively.

An 18-year-old female patient presented with a 1-month history of low back pain, which had worsened and was accompanied by radiating pain in the right lower limb for half a month. She was admitted to our hospital with computed tomography and magnetic resonance imaging findings suggesting calcification of the L3/4 disc and a large intraspinal mass at the L2-4 level. The patient's symptoms did not improve with conservative treatment, and her muscle strength rapidly declined.

Background: On June 13, 2020, an explosion involving a liquefied natural gas (LNG) tanker truck occurred in eastern China. Fifteen patients with extremely severe burns (referred to as "June 13" patients) were treated in the burn-intensive care unit (ICU) joint ward within the general ICU.
Methods: A multidisciplinary treatment team comprising 129 doctors, 126 nurses, and 165 auxiliary staff members was assembled.
Cardiac dilation, energy stress and ventricular remodeling: insights from prolonged voluntary exercise in male mice with TAC-induced HFpEF.

Exercise in heart failure with preserved ejection fraction (HFpEF) remains a hot topic, although current treatment strategies have not been shown to improve the long-term prognosis of HFpEF. Previous studies have mostly focused on the roles of endurance training, the mechanisms underlying long-term voluntary exercise have not been elucidated. The purpose of the present analysis was to evaluate alterations in cardiac function in HFpEF mice (HFpEF-Sed) after 6 weeks of voluntary running (HFpEF-Ex), investigate mechanisms, and compare the effects with fluoxetine (HFpEF-FLX).
