Seeds are colonized by diverse microorganisms that can improve the growth and stress resistance of host plants. Although understanding the mechanisms of plant endophyte-host plant interactions is incr...
EHMT1 is an epigenetic factor with histone methyltransferase activity that appears mutated in Kleefstra syndrome, a neurodevelopmental genetic disorder characterized by developmental delay, intellectu...
CCN proteins play important functions during development, in repair mechanisms following tissue injury, as well as in pathophysiologic mechanisms of metastasis of cancer. CCNs are secreted proteins th...
Contrast processing is a fundamental function of the visual system, and contrast sensitivity as a function of spatial frequency (CSF) provides critical information about the integrity of the system. H...
The amino acids l-arginine and l-ornithine are widely used in animal feed and as health supplements and pharmaceutical compounds. In arginine biosynthesis, acetylornithine aminotransferase (AcOAT) use...
Since the hippocampus is predominantly susceptible to injuries caused by COVID-19, there are increasing data indicating the likelihood of post-infection memory loss and quickening neurodegenerative di...
Interleukin-11 (IL-11) is linked to the pathogenesis of idiopathic pulmonary fibrosis (IPF), since IL-11 induces myofibroblast differentiation and stimulates their excessive collagen deposition in the...
We hypothesised that epithelial-fibroblast communication associated with lung repair is disrupted by IL-11. Thus, we studied whether IL-11 affects the repair responses of alveolar lung epithelium usin...
IL-11 protein was observed in airway epithelium, macrophages and in IPF lungs, also in areas of alveolar type 2 (AT2) cell hyperplasia. IL-11R staining was predominantly present in smooth muscle and m...
IL-11 disrupts alveolar epithelial regeneration by inhibiting progenitor activation and suppressing the formation of mature alveolar epithelial cells. Evidence for a contribution of dysregulated fibro...
Cancer immunotherapy is shifting paradigms in cancer care. T cells are an indispensable component of an effective antitumor immunity and durable clinical responses. However, the complexity of the tumo...
Cognitive impairment often occurs secondary to epilepsy. This study aims to evaluate the cognitive functions of patients with idiopathic generalized epilepsy (IGE) by using the digital neuropsychologi...
Seventy-nine patients diagnosed with IGE in the last 10 years in our clinic, who completed at least eight years of education were recruited. Participants who met the criteria were 36 individuals with ...
IGE patients showed lower cognitive performance in attention, short-term memory, working memory, visual memory, episodic memory, cognitive processing speed, response selection/inhibition, fluid cognit...
IGE patients performed significantly worse outcomes in some tests of the TMB. In this study, it is aimed to emphasize the necessity of evaluating the cognitive aspects of epilepsy patients, which will...
Uncoordinated 51-like kinase 1 (ULK1) is an essential part involved in autophagy to maintain cell viability and homeostasis. Herein, the expression levels of ULK1 in colon cancer (CC) were investigate...
