Pure Acute Subdural Hematoma of Cortical Non-mycotic Microaneurysmatic Etiology: A Report of Two Cases and a Literature Review.

Pure acute subdural hematoma (ASDH) is an uncommon clinical presentation of ruptured intracranial aneurysms, and only rarely, the culprit is a cortical microaneurysm.Mortality can be high; thus, appropriate diagnosis and treatment are crucial. Due to its extreme rarity, there are no available guidelines.

Analysis of Synovial Fluid Metabolic Profile in Patients with Knee Osteoarthritis Using Spectroscopic Magnetic Resonance Metabolomics.

 The present study aimed to evaluate the metabolic profile of synovial fluid in patients with knee osteoarthritis (KOA) and its correlation with clinical data.  We collected synovial fluid samples from the knees of 50 subjects with KOA undergoing total knee arthroplasty from October 2019 to December 2020. For each patient, we evaluated the clinical data from the medical record, the radiographic osteoarthritis grade, and the preoperative fasting blood glucose levels.

USE OF DECELLULARIZED HUMAN AMNIOTIC MEMBRANE IN INTESTINAL ANASTOMOSES: A STUDY IN RATS TREATED WITH 5-FLUOROURACIL.

Background: Nowdays, more relevant applications of perinatal derivatives, such as amniotic membrane (AM), are emerging in our environment as a source of biomaterials for use in different healing processes. The study of anastomosis healing associated with antimetabolic drugs such as 5-fluorouracil (5-FU) is a potential target of AM.

Aims: To evaluate the healing effects of AM in rats treated with 5-FU at a dose of 20 mg/kg on the seventh day of postoperative evolution, regarding the parameters percentage of type I collagen (mature), cell viability, microvascular density and formation of granulation tissue.

Terpyridine-based ruthenium complexes containing a 4,5-diazafluoren-9-one ligand with light-driven enhancement of biological activity.

There has been growing effort in the scientific community to develop new antibiotics to address the major threat of bacterial resistance. One promising approach is the use of metal complexes that provide broader opportunities. Among these systems, polypyridine-ruthenium(II) complexes have received particular attention as drug candidates.
