Microsurgical Anatomy of the Lateral Posterior Choroidal Artery and Its Thalamic Branches.

Background: Only a few articles have been published about the lateral posterior choroidal artery (LPChA), and yet none of them contains data regarding the thalamic branches.

Methods: The LPChA and its twigs of the 26 cerebral hemispheres were injected with a mixture of a 10% Indian ink and gelatin. Following fixation in a 10% formaldehyde solution, the vessels were micro dissected under the stereoscopic microscope.

Methodological challenges in using human umbilical artery as a model for in vitro studies.

New Findings: What is the central question of this study? What are the biggest challenges in performing in vitro studies on isolated human umbilical arteries? What is the main finding and its importance? The protocols presented in this study indicate some potential outcomes important for interpretation of the vascular responsivities of human umbilical arteries and could be useful for planning future in vitro studies with human umbilical arteries.

Abstract: Human umbilical artery (HUA) preparations are of particular importance for in vitro studies on isolated blood vessels because their sampling is not risky for the patient, and they can provide the closest possible impression of changes related to the uteroplacental circulation during pre-eclampsia. Using organ bath techniques, useful experimental protocols are provided for measuring some pathophysiological phenomena in the vascular responses of HUAs.

Association between affective temperaments and psychosomatic symptoms in women with Hashimoto's thyroiditis.

Background: Hashimoto's thyroiditis (HT) is a prevalent autoimmune disease of thyroid gland with a shared immunological mechanism with mood disorders. Affective temperament (AT) is a biologically determined personality trait that has been linked to mood disorders. The aim of this study was to examine the association between dominant AT and levels of psychosomatic symptoms in women newly diagnosed with HT in comparison to clinically healthy subjects.

Pomegranate Peel Extract Attenuates Isoprenaline-Induced Takotsubo-like Myocardial Injury in Rats.

Takotsubo syndrome (TTS) is an acute heart failure syndrome characterised by catecholamine-induced oxidative tissue damage. , a fruit-bearing tree, is known to have high polyphenolic content and has been proven to be a potent antioxidant. This study aimed to investigate the effects of pomegranate peel extract (PoPEx) pre-treatment on isoprenaline-induced takotsubo-like myocardial injury in rats.

Medullary branches of the vertebral artery: microsurgical anatomy and clinical significance.

Background: Since the medullary arteries are of a great neurologic and neurosurgical significance, the aim was to perform a detailed microanatomic study of these vessels, as well as of the medullary infarctions in a group of patients.

Methods: The arteries of 26 halves of the brain stem were injected with India ink and gelatin, microdissected and measured with an ocular micrometer. Neurologic and magnetic resonance imaging (MRI) examinations were performed in 11 patients.
