Encephalitis by Epstein Barr Virus in a Transplant Immunosuppressed Patient.

Encephalitis due to Epstein-Barr Virus (EBV) is a rare condition that primarily affects children and immunosuppressed patients. Diagnosing EBV encephalitis can be challenging due to its nonspecific clinical presentation and the lack of confirmatory tests. We present the case of a 66-year-old woman with a history of kidney transplantation who was admitted due to progressive subacute mental deterioration, preceded by vertigo and without fever.

Constitutive HIF-1α Expression in the Epidermis Fuels Proliferation and Is Essential for Effective Barrier Formation.

Epidermis is one of the most rapidly proliferating tissues in the body with high demands for adenosine triphosphate and cellular building blocks. In this study, we show that to meet these requirements, keratinocytes constitutively express HIF-1α, even in the presence of oxygen levels sufficient for HIF-1α hydroxylation. We previously reported that mice with severe epidermal mitochondrial dysfunction actually showed a hyperproliferative epidermis but rapidly died of systemic lactic acidosis and hypoglycemia, indicating excessive glycolysis.

Admissions by tuberculosis in a regional reference Center. A complex and worrying scenario.

Objectives: To characterize clinical aspects, evaluate the diagnostic opportunity, and identify factors associated with mortality in patients hospitalized for tuberculosis (TB).

Methods: Retrospective study of patients admitted for TB to a Regional Hospital in Chile between 2011 and 2019.

Results: 142 TB events required hospitalization in this period (38.

Selective Hypoxia-Sensitive Oxomer Formation by FIH Prevents Binding of the NF-κB Inhibitor IκBβ to NF-κB Subunits.

Pharmacologic inhibitors of cellular hydroxylase oxygen sensors are protective in multiple preclinical models of inflammation. However, the molecular mechanisms underlying this regulation are only partly understood, preventing clinical translation. We previously proposed a new mechanism for cellular oxygen sensing: oxygen-dependent, (likely) covalent protein oligomer (oxomer) formation.

Design, Stereolithographic 3D Printing, and Characterization of TPMS Scaffolds.

Anatomical and functional tissue loss is one of the most debilitating problems and involves a great cost to the international health-care sector. In the field of bone tissue, the use of scaffolds to promote tissue regeneration is a topic of great interest. In this study, a combination of additive manufacturing and computational methods led to creating porous scaffolds with complex microstructure and mechanical behavior comparable to those of cancellous bone.
