Novel synthesized pyrimidine derivatives were investigated against carbonic anhydrase isoenzymes I and II (hCA I and II), acetylcholinesterase (AChE), butyrylcholinesterase (BChE), α-glycosidase, and aldose reductase (AR) enzymes associated with some common diseases such as epilepsy, glaucoma, Alzheimer's disease, diabetes, and neuropathy. When the results were examined, novel synthesized pyrimidine derivatives were found to have effective inhibition abilities toward the metabolic enzymes. IC values and K values were calculated for each pyrimidine derivative and compared to positive controls.

Purpose: To investigate the effect of the coexistence of fetal-type posterior communicating artery (fPCA) and anterior cerebral artery (ACA) A1 segment agenesis/hypoplasia on the rupture of an anterior communicating artery (AComA) aneurysm.

Materials And Methods: A total of 216 patients consecutively presenting with AComA aneurysms between January 2014 and December 2021 on digital subtraction angiography were evaluated. Patients without three-dimensional rotational angiography images, those aged under 18 years, those with suspected mycotic aneurysms, and those with dissecting and giant aneurysms were excluded from the study.

Objectives: A surgery to be performed on a previously operated neck includes difficulties such as increased risk of complications and prolonged operation time. The aim of the present study is to analyze the benefit of pre-anesthetic ultrasound-guided injection of methylene blue into parathyroid adenomas and abnormal lymph nodes to simplify their safe and satisfactory extraction.

Methods: We analyzed the case series records of 14 patients who were operated for reoperative neck surgery due to recurrent thyroid cancer (8 patients) and parathyroid adenoma (6 patients) and in the technique; 0.

Soluble ACE2 (sACE2) decoys are promising agents to inhibit SARS-CoV-2, as their efficiency is unlikely to be affected by escape mutations. However, their success is limited by their relatively poor potency. To address this challenge, multimeric sACE2 consisting of SunTag or MoonTag systems is developed.

Carotid blowout syndrome is a rare clinical conditions with a high mortality rate, especially in patients with head and neck tumors who have received radiotherapy and chemotherapy. We present our patient who had hemangioendothelioma of the neck for 5 years and therefore received radiotherapy, fistulized to the skin on the neck and active bleeding out of the fistula area. In the radiological imaging of the patient, vessel wall irregularities in the common carotid artery (CCA) and accompanying pseudoaneurysm with a diameter of 3 cm were detected, and endovascular treatment was performed.

Background: Vaccines that incorporate multiple SARS-CoV-2 antigens can further broaden the breadth of virus-specific cellular and humoral immunity. This study describes the development and immunogenicity of SARS-CoV-2 VLP vaccine that incorporates the four structural proteins of SARS-CoV-2.

Methods: VLPs were generated in transiently transfected HEK293 cells, purified by multimodal chromatography, and characterized by tunable-resistive pulse sensing, AFM, SEM, and TEM.

Background: The known primary radiological diagnosis of Chiari Malformation-I (CM-I) is based on the degree of tonsillar herniation (TH) below the Foramen Magnum (FM). However, recent data also shows the association of such malformation with smaller posterior cranial fossa (PCF) volume and the anatomical issues regarding the Odontoid. This study presents the achieved result regarding some detected potential radiological findings that may aid CM-I diagnosis using several machine learning (ML) algorithms.

Background: The objective of the present study is to analyze the outcomes of patients with subarachnoid hemorrhage (SAH) in the acute phase after treatment with Y-stent-assisted coiling (YSAC) embolization.

Methods: This retrospective study assessed of 30 patients with acutely ruptured wide-neck aneurysms following YSAC treatment between April 2013 and October 2019. The demographic data, aneurysm occlusion grade, procedural and periprocedural complications, and clinical outcomes were assessed.

Aim: To determine the effectiveness of diffusion tensor imaging (DTI) in diagnosing cervical spondylotic myelopathy (CSM) in patients with no findings detected in conventional magnetic resonance imaging (MRI).

Material And Methods: Fifty-four patients who presented for cervical MRI between January 2016 and June 2016, with symptoms such as neck pain, paresis, and numbness in hands, were included in the study. The patients were split into four groups based on their degrees of spinal stenosis.

Aim: To estimate the rupture risk of anterior communicating artery (AComA) and AComA-related aneurysms according to their localization, angiographic architecture, and morphological features.

Material And Methods: In this study, 124 patients with AComA and AComA-related anterior system aneurysms were retrospectively evaluated. The aneurysms were classified according to their morphological appearance and angiographic architecture.

Carotid artery pseudoaneurysm are a rare complication of deep neck infections, especially in the antibiotic era. Although it is rare, it may result in life-threatening conditions. Here, the authors present a case of pseudoaneurysm of the carotid artery caused by parapharyngeal abscess and causing massive oropharyngeal bleeding and treat with endovascular approach in a 40-year-old woman presenting with neck swelling and fever.

Pyrrole carboxamide rings are rarely used as active scaffold in designing inhibitors for enzymes. Herein, we described the structure-activity relationship for novel xanthine oxidase inhibitors based on the pyrrole carboxamide scaffold. A series of novel-substituted pyrrole carboxamide derivatives were synthesized and characterized; their in vitro and in silico inhibitory activities were determined against xanthine oxidase.
