Absence of occult hepatitis B among blood donors in southern Brazil

open access: yesBrazilian Journal of Infectious Diseases, 2011
Background: Occult hepatitis B virus (HBV) infection is characterized by the detection of HBV DNA in serum and/or in liver in the absence of detectable hepatitis B surface antigen (HBsAg).

Factors Predicting Fecal Occult Blood Testing among Residents of Bushehr, Iran, Based on the Health Belief Model [PDF]

open access: yes, 2016
Colorectal cancer is a major cause of mortality worldwide. Fecal occult blood testing has proven a very effective screening tool for early detection and mortality reduction.

Dynamic Modulation of the Microenvironment Promotes Functional Maturation of Engineered Tissues

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered tissues lack the dynamic microenvironment of native tissues. A biocompatible, diffusible small molecule to dynamically modulate tissue microenvironments during maturation is used. Timing‐dependent modulation yields distinct outcomes, producing thicker, more native‐like blood vessels, stronger and more mature cardiac tissues, and optimized ...

A Modular Bioinstructive Platform Reveals Mechanistic Insights into Additive‐Free, Topography‐Driven Osteogenesis

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

Diagnostic value of pyruvate kinase isoenzyme type M2 in colon cancer proven with colonoscopy

open access: yesAdvanced Biomedical Research, 2020
Background: Colonoscopy is the gold standard for colon cancer screening; it is also associated with a high cost and complication. Proliferating cells, in particular tumor cells, express a dimeric isoenzyme of pyruvate kinase, termed M2 pyruvate kinase ...

A rare presentation of gastrointestinal stromal tumor arising from a meckel's diverticulum: A case report

open access: yesJournal of Family Medicine and Primary Care, 2022
The most common congenital gastrointestinal tract abnormality is Meckel's diverticulum, affecting 1% to 2% of the population. Meckel's diverticulum can sometimes house a gastrointestinal stromal tumor (GIST), which is a rare malignant tumor.

Severe acute axonal neuropathy following treatment with arsenic trioxide for acute promyelocytic leukemia: a case report [PDF]

open access: yes, 2016
Peripheral neuropathy is a common complication of arsenic toxicity. Symptoms are usually mild and reversible following discontinuation of treatment. A more severe chronic sensorimotor polyneuropathy characterized by distal axonal-loss neuropathy can be ...

Copolymers of Poly(Butylene Trans‐1,4‐Cyclohexanedicarboxylate)/Pripol as New Biomaterial Platform for Small Diameter Vascular Graft

open access: yesAdvanced Healthcare Materials, EarlyView.
Electrospun tubular scaffolds from novel PBCE‐based copolyesters and blends were designed as candidates for small‐diameter vascular grafts. They combine defect‐free architecture, blood‐compatible surfaces, and mechanical properties comparable to native vessels.

Differential Diagnoses of Systemic Mastocytosis in Routinely Processed Bone Marrow Biopsy Specimens: A Review [PDF]

open access: yes, 2010
Diagnosis of systemic mastocytosis (SM) is mainly based on the morphological demonstration of compact mast cell infiltrates in various tissue sites. In almost all patients such infiltrates are detected in the bone marrow.

Temporally Delayed Deployment of Photo‐Responsive Liquid Crystal Polymer Networks Toward Neural Interfaces

open access: yesAdvanced Healthcare Materials, EarlyView.
Deployable medical devices typically need external stimuli to trigger deployment. However, external stimuli are difficult to supply within tissues. Here, we describe a strategy to deploy small‐scale structures into soft tissues after insertion without the need for any stimulus. We demonstrate deployment within a tissue phantom.
