Background/aim: We aimed to determine in which cases this procedure may be more effective based on the data of patients who underwent decompressive hemicraniectomy (DHC). Material and methods: Overall, 47 patients who underwent DHC due to acute middle cerebral artery (MCA) infarction between January 2014 and january 2019 were retrospectively investigated. These patients were divided into two groups: those who died after DHC (Group A) and those who survived DHC (Group B). The groups were compared in terms of various parameters. We investigated whether the patient's modified Rankin scale (mRS) status changed depending on age (> 60 and < 60 years). Results: The median age of all patients was 65 (37-80) years; groups A and B had median ages of 66.5 (37-80) and 61 (44-79) years (p = 0.111), respectively; 55.3% patients were male. The elapsed times until hospitalization after the onset of symptoms were 4.5 and 3 h in groups A and B, respectively (p = 0.014). The median GCS score at the time of admission was 7 (5-12) and 10 (8-14) in groups A and B, respectively (p = 0.0001). At the time of admission, 63.3% patients in group A had anisocoria, whereas no patient in group B had anisocoria (p = 0.0001). In postoperative period, 40% patients in group A and all patients in group B received AC/AA treatment. The survival of patients aged < 60 and > 60 years …

A Cell Protective Mechanism In A Murine Model Of Parkinson's Disease, Emi̇n Öztaş, Turgut Topal
Turkish Journal of Medical Sciences
Parkinson's disease is characterized by progressive degeneration of the dopaminergic (DA) neurons in the substantia nigra (SN). However, the mechanism underlying DA cell death remains unclear. While apoptotic cell death has been implicated in DA cell death in Parkinson's disease, autophagy - a regulated cellular process for degrading intracellular proteins and organelles under stress - in Parkinson's disease is not known. Here, we report evidence of autophagy in DA neurons of the SN in a 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) model of Parkinson's disease. Mice were treated with saline or MPTP (40 mg/kg) and sacrificed after 7 days, and brain tissue samples were …
