A pathogenic role for IL-10 signalling in capillary stalling and cognitive impairment in type 1 diabetes.

Vascular pathology is associated with cognitive impairment in diseases such as type 1 diabetes; however, how capillary flow is affected and the underlying mechanisms remain elusive. Here we show that capillaries in the diabetic mouse brain in both sexes are prone to stalling, with blocks consisting primarily of erythrocytes in branches off ascending venules. Screening for circulating inflammatory cytokines revealed persistently high levels of interleukin-10 (IL-10) in diabetic mice.

Postfasciotomy Classification System for Acute Compartment Syndrome of the Leg.

Objective: Acute compartment syndrome (ACS) is a true emergency. Even with urgent fasciotomy, there is often muscle damage and need for further surgery. Although ACS is not uncommon, no validated classification system exists to aid in efficient and clear communication.

Optical opening of the blood-brain barrier for targeted and ultra-sparse viral infection of cells in mouse cortex.

Adeno-associated viruses (AAVs) are used in a wide array of experimental situations for driving expression of biosensors, recombinases, and opto-/chemo-genetic actuators in the brain. However, conventional approaches for minimally invasive, spatially precise, and ultra-sparse AAV-mediated transduction of cells during imaging experiments have remained a significant challenge. Here, we show that intravenous injection of commercially available AAVs at different doses, combined with laser-based perforation of cortical capillaries through a cranial widow, allows for ultra-sparse, titratable, and micron-level precision for delivery of viral vectors with relatively little inflammation or tissue damage.

Index admission vs elective laparoscopic common bile duct exploration: a district general hospital experience over 6 years.

Background: Laparoscopic common bile duct exploration (LCBDE) is relatively a new approach for clearing choledocholithiasis. The aim of this study is to assess the safety of this approach to clearing common bile duct (CBD) stones on an index admission including emergency setting.

Methods: Retrospective data collection and analysis were carried out for 207 consecutive cases of LCBDE performed in Royal Cornwall Hospital over 6 years (2015-2020).

Somatic yolk sac differentiation in tumors of the gynecologic tract: A report of two cases and review of the literature.

•Somatic yolk sac tumor differentiation associated with malignant neoplasms is uncommon and associated with poor outcome.•In the gynecologic tract, somatic yolk sac differentiation most often arises in postmenopausal patients.•Somatic yolk sac differentiation shares driver mutations with and likely differentiates from the corresponding carcinoma.
