Deep brain stimulation (DBS) is a well-established treatment for motor circuit disorders such as Parkinson disease, dystonia, and essential tremor, particularly when pharmacological interventions are insufficient. The increase in DBS-related publications and the growing number of patients receiving DBS highlight the acceptance and refinement of the procedure. Despite its widespread use, comprehensive anatomical knowledge of deep brain nuclei remains critical for enhancing clinical efficacy.

Graftless Primary Dural Closure Following Retrosigmoid Approach: Doing More With less.

Introduction: Achieving watertight dural closure without grafts via the retrosigmoid approach can be challenging, contributing to a significant rate of postoperative cerebrospinal fluid (CSF) leaks. This study describes a dural incision technique for achieving primary dural closure without grafts following the retrosigmoid approach and presents clinical data from the authors' experience.

Methods: Clinical and surgical data of 227 patients who underwent the dural incision technique following the retrosigmoid approach for various pathologies were retrospectively reviewed.

Revisiting the microsurgical anatomy of the sagittal stratum and surgical implications: fiber microdissection and tractography study.

Objective: The term "sagittal stratum" was coined by Heinrich Sachs in 1892 to define a parasagittally oriented white matter layer at the temporo-occipital cortex. Although this term has been widely used for more than 100 years, the description, classification, borders, and involved fibers of the structure vary among authors and remain imprecise. Through fiber microdissection and tractography, the authors aimed to define the sagittal stratum and resolve the uncertainty by revealing the relationship of this structure to other cerebral white matter pathways and the orientation of fibers in it.

Creation of a microsurgical neuroanatomy laboratory and virtual operating room: a preliminary study.

Objective: A comprehensive understanding of microsurgical neuroanatomy, familiarity with the operating room environment, patient positioning in relation to the surgery, and knowledge of surgical approaches is crucial in neurosurgical education. However, challenges such as limited patient exposure, heightened patient safety concerns, a decreased availability of surgical cases during training, and difficulties in accessing cadavers and laboratories have adversely impacted this education. Three-dimensional (3D) models and augmented reality (AR) applications can be utilized to depict the cortical and white matter anatomy of the brain, create virtual models of patient surgical positions, and simulate the operating room and neuroanatomy laboratory environment.

The role of an open artificial intelligence platform in modern neurosurgical education: a preliminary study.

It is necessary to explore the potential of this program in neurosurgery education and to evaluate its reliability.

Does the menstrual phase affect gastric emptying? Prospective, observational study.

Objective: Pulmonary aspiration of gastric content is a serious complication of anesthesia. It is unclear what effects different parts of the menstrual cycle have on how long it takes for the stomach to empty. This prospective observational study assessed the relationship between menstrual cycle phases and gastric emptying using ultrasonography (USG) in volunteers of reproductive age.

Aortic Valve Neocuspidization Procedure Provides Better Postoperative Outcomes When Compared to Rapid Deployement Aortic Valves.

Background: The aim of this study was to compare the early results of rapid deployment aortic valves (RD-AVR) and aortic valve neocuspidization (AVNeo) techniques.

Methods: Between December 2019 to May 2022, 104 patients were operated on with aortic stenosis by RD-AVR (N = 52) and AVNeo (N = 52) techniques. Patients with isolated aortic valve stenosis and aortic stenosis concomittant with planned other cardiac surgeries were included.

Analyzing the effect of data preprocessing techniques using machine learning algorithms on the diagnosis of COVID-19.

Real-time polymerase chain reaction (RT-PCR) known as the swab test is a diagnostic test that can diagnose COVID-19 disease through respiratory samples in the laboratory. Due to the rapid spread of the coronavirus around the world, the RT-PCR test has become insufficient to get fast results. For this reason, the need for diagnostic methods to fill this gap has arisen and machine learning studies have started in this area.

Comparison of the Results of Suture and Resorbable Plate-Screw Fixation in Craniosynostosis.

Background: Although many fixation methods are used alone or in combination for craniosynostosis, only few studies have compared the effectiveness and long-term results of these methods.

Method: In this study, patients in whom suture or resorbable plate-screw system was used for fixation were evaluated in terms of postoperative results and complications. The data of patients who underwent surgery for craniosynostosis between 2002 and 2019 were retrospectively reviewed and evaluated.

ERO1 alpha deficiency impairs angiogenesis by increasing N-glycosylation of a proangiogenic VEGFA.

N-glycosylation and disulfide bond formation are two essential steps in protein folding that occur in the endoplasmic reticulum (ER) and reciprocally influence each other. Here, to analyze crosstalk between N-glycosylation and oxidation, we investigated how the protein disulfide oxidase ERO1-alpha affects glycosylation of the angiogenic VEGF, a key regulator of vascular homeostasis. ERO1 deficiency, while retarding disulfide bond formation in VEGF, increased utilization of its single N-glycosylation sequon, which lies close to an intra-polypeptide disulfide bridge, and concomitantly slowed its secretion.
