Effects of the nematode subsp. and beech leaf disease on leaf fungal and bacterial communities on (American beech).

Unlabelled: Beech leaf disease (BLD) is a newly emerging disease in North America that affects American beech (). It is increasingly recognized that BLD is caused by a subspecies of the anguinid nematode subsp. (hereafter ) which is likely native to East Asia.

Through the Looking Glass: Surveillance Following Colonoscopic Polypectomy of Malignant Polyps.

Introduction Colonoscopic polypectomy is a well-established screening and surveillance modality for malignant colorectal polyps. Following the detection of a malignant polyp, patients are either put on endoscopic surveillance or planned for a surgical procedure. We studied the outcome of colonoscopic excision of malignant polyps and their recurrence rates.

Characteristics Of Medical Device Shortages In The US, 2006-20.

Shortages of critical medical devices during the COVID-19 pandemic exposed vulnerabilities in device markets. From 2010 to 2019 there were approximately five shortages annually, but that number increased fourfold in the first half of 2020. Although most 2020 shortages were triggered by the pandemic, pre-2020 shortages stemmed from regulatory and enforcement actions related to product quality and manufacturing.

Primary Effusion Lymphoma: A Clinicopathologic Perspective.

Primary effusion lymphoma (PEL) is a rare, aggressive B-cell lymphoma that usually localizes to serous body cavities to subsequently form effusions in the absence of a discrete mass. Although some tumors can develop in extracavitary locations, the areas most often affected include the peritoneum, pleural space, and the pericardium. PEL is associated with the presence of human herpesvirus 8 (HHV8), also called the Kaposi sarcoma-associated herpesvirus (KSHV), with some variability in transformation potential suggested by frequent coinfection with the Epstein-Barr virus (EBV) (~80%), although the nature of the oncogenesis is unclear.

Multidisciplinary Management of Adolescent and Young Adult Patients with Hodgkin Lymphoma.

Successful management of adolescent and young adult patients with Hodgkin lymphoma (HL) requires a multidisciplinary approach to care with special attention paid to the unique medical, logistical, and psychosocial challenges faced by this group. The emotional and social changes and big life transitions that occur between the ages of 15 and 39 result in a broad scope of supportive care needs that differ from children or adults in similar circumstances. Currently, care of adolescent and young adult (AYA) patients with HL may be fractured across the pediatric-adult cancer care continuum resulting in this group being less well studied than pediatric or adult patients in general.

Sex hormones regulate NHE1 functional expression and brain endothelial proteome to control paracellular integrity of the blood endothelial barrier.

Background: Sex hormones have been implicated in pH regulation of numerous physiological systems. One consistent factor of these studies is the sodium-hydrogen exchanger 1 (NHE1). NHE1 has been associated with pH homeostasis at epithelial barriers.

Loss of Blood-Brain Barrier Integrity in a KCl-Induced Model of Episodic Headache Enhances CNS Drug Delivery.

Cortical spreading depression (CSD) in the CNS is suggested as a common mechanism contributing to headache. Despite strong evidence for CNS involvement in headache disorders, drug development for headache disorders remains focused on peripheral targets. Difficulty in delivering drugs across the blood-brain barrier (BBB) may partially account for this disparity.

Two-stage fungal biopulping for improved enzymatic hydrolysis of wood.

A novel two-stage, whole organism fungal biopulping method was examined for increasing the yield of enzymatic hydrolysis of wood into soluble glucose. Liriodendron tulipifera wood chips (1g) were exposed to liquid culture suspensions of white rot (Ceriporiopsis subvermispora) or brown rot (Postia placenta) fungi and incubated at 28°C, either alone in single-stage 30 day (one fungal species applied) or two-stage 60 day (both fungal species applied in alternative succession) treatments. Fungi grew in all treatments, but did not significantly decrease the percent carbohydrate content of the wood.
