Abnormal brain oxygen homeostasis in an animal model of liver disease

Cristina Ramona Cudalbu, Katarzyna Pierzchala, Dunja Simicic

Background & Aims: Increased plasma ammonia concentration and consequent disruption of brain energy metabolism could underpin the pathogenesis of hepatic encephalopathy (HE). Brain energy homeostasis relies on effective maintenance of brain oxygenation, an ...

Central Nervous System Oxidative Stress Interplay With Inflammation In A Rat Model Of Type C Hepatic Encephalopathy - Brothers In Arms?

Cristina Ramona Cudalbu, Katarzyna Pierzchala, Dunja Simicic, Stefanita-Octavian Mitrea

ELSEVIER SCIENCE INC2022

Central nervous system and systemic oxidative stress interplay with inflammation in a bile duct ligation rat model of type C hepatic encephalopathy

Rolf Gruetter, Cristina Ramona Cudalbu, Andrzej Sienkiewicz, Katarzyna Pierzchala, Dunja Simicic, Stefanita-Octavian Mitrea

The role and coexistence of oxidative stress (OS) and inflammation in type C hepatic encephalopathy (C HE) is a subject of intense debate. Under normal conditions the physiological levels of intracellular reactive oxygen species are controlled by the count ...

Central nervous system and systemic oxidative stress interplay with inflammation in a bile duct ligation rat model of type C hepatic encephalopathy (vol 178, pg 295, 2022)

Rolf Gruetter, Cristina Ramona Cudalbu, Andrzej Sienkiewicz, Katarzyna Pierzchala, Dunja Simicic, Stefanita-Octavian Mitrea

ELSEVIER SCIENCE INC2022

Chromophore of an Enhanced Green Fluorescent Protein Can Play a Photoprotective Role Due to Photobleaching

László Forró, Andrzej Sienkiewicz, Katarzyna Pierzchala

Under stress conditions, elevated levels of cellular reactive oxygen species (ROS) may impair crucial cellular structures. To counteract the resulting oxidative damage, living cells are equipped with several defense mechanisms, including photoprotective fu ...

Probiotics combined with rifaximin influence the neurometabolic changes in a rat model of type C HE

Rolf Gruetter, Cristina Ramona Cudalbu, Katarzyna Pierzchala, Emmanuelle Ines Flatt

Type C hepatic encephalopathy (HE) is a neuropsychiatric disease caused by chronic liver disease. Management of type C HE remains an important challenge because treatment options are limited. Both the antibiotic rifaximin and probiotics have been reported ...

Synchronous nonmonotonic changes in functional connectivity and white matter integrity in a rat model of sporadic Alzheimer's disease

Bernard Lanz, Katarzyna Pierzchala, Ileana Ozana Jelescu, Carole Poitry-Yamate, Ting Yin, Yujian Diao

Brain glucose hypometabolism has been singled out as an important contributor and possibly main trigger to Alzheimer's disease (AD). Intracerebroventricular injections of streptozotocin (icv-STZ) cause brain glucose hypometabolism without systemic diabetes ...

Thyrotropin-secreting pituitary adenomas: a systematic review and meta-analysis of postoperative outcomes and management

Katarzyna Pierzchala

PurposeTSH-secreting pituitary adenomas are rare pituitary tumors. An efficient treatment is essential to limit the mortality and morbidity in untreated patients. The aim of this study is to summarize the evidence about the postoperative outcomes and manag ...

Residual hip dysplasia in children: osseous and cartilaginous acetabular angles to guide further treatment-a pilot study

Katarzyna Pierzchala

Purpose In case of residual hip dysplasia (RHD) in children, pelvic radiographs are sometimes insufficient to precisely evaluate the entire coverage of the femoral head, when trying to decide on the need for further reconstructive procedures. Methods This ...
