Objectives: To investigate the latencies, amplitudes of R1, R2i and R2k responses and R2 habituation; to compare the groups with each other and with the placebo group and to demonstrate new evidences on migraine and tension-type headache TTH mechanisms.
Methods: This analytical study was carried out among 40 migraine patients who were admitted to Yuzuncu Yil University, Medical Faculty, Neurology Clinics between May 2009 and December 2009, with or without aura according to the diagnostic criteria of International Headache Society 2004 classification. Forty TTH patients, who were diagnosed with TTH were included, and 40 control group subjects were formed according to the same demographic data. SPSSv13 was used for Chi-square test, one-way ANOVA and Pearson correlation coefficients was used for the determination of the relation between the groups and categorical.
Results: Mean age was 33.04 +/- 9.07 years. An average of RR2k latency was significantly high in migraine group comparing with TTH and the control groups, and in TTH group comparing with the control group. Similarly, the average of LR2k latency was found to be significantly higher in migraine group than TTH and the control groups, and significantly higher in TTH group than the control group.
Conclusion: Our findings demonstrated that brainstem and trigeminovascular connections play an important role in migraine pathogenesis and that central mechanisms play a role in TTH and concerning these two diseases.

Organic redox systems that can undergo oxidative and reductive (ambipolar) electron transfer are elusive yet attractive for applications across synthetic chemistry and energy science. Specifically, the use of ambipolar redox systems in proton-coupled electron transfer (PCET) reactions is largely unexplored but could enable "switchable" reactivity wherein the uptake and release of hydrogen atoms are controlled using a redox stimulus. Here, we describe the synthesis and characterization of an ambipolar functionalized terthiophene (TTH) bearing methyl thioether and phosphine oxide groups that exhibits switchable PCET reactivity.

Thermus thermophilus HB27 laccase (Tth-Lac) is a thermostable enzyme that contains a β-hairpin (Ala292-Gln307) covering the substrate entrance. We analyzed the role of this β-hairpin in the enzymatic activity of Tth-Lac through three β-hairpin mutants: two variants without the β-hairpin (C1Tth-Lac and C2Tth-Lac) and one with a partially modified β-hairpin (P1Tth-Lac). Enzymatic activity was assayed with different substrates with and without copper.

Objectives: Migraine is a common cause of headache and a leading cause of morbidity in Türkiye. This study aimed to describe the clinical characteristics and management of migraine and to compare migraine with tension-type headache (TTH) regarding the burden of disease and healthcare resource utilization.
Methods: A total of 1368 patients (aged 18-65 years) with migraine or TTH were surveyed regarding sociodemographics, headache characteristics, clinical management, disease burden, quality of life, and healthcare resource utilization within the previous 12 months.

Background: This study aims to compare the posterior ocular structure parameters in children with migraine without aura (MWA), tension-type headache (TTH), and a healthy control group.
Methods: The study included 31 patients with MWA, 29 patients with TTH, and 38 healthy controls between 6 and 18 years of age. For all participants, the detailed eye examination and measurements including peripapillary retinal nerve fiber layer (pRNFL) thickness, central macular thickness (CMT), subfoveal choroidal thickness (SCT), macular vessel densities and foveal avascular zone (FAZ) parameters measured by optical coherence tomography (OCT) and OCT-angiography (OCTA), were obtained from the patient files.

Objective: To evaluate whether patients with tension-type headache (TTH) exhibit abnormal brain functional connectivity compared to healthy controls.
Background: TTH is one of the most prevalent headache disorders throughout the world. The present study delves into brain functional connectivity in patients with TTH to enhance the understanding of its underlying pathophysiology.
