Migraine is recognized as a complex neurological disorder that has imposed a social burden. We assessed the signaling pathways and molecular mechanisms based on the in silico analysis and predicted drug candidates by the biomedicine approach. Moreover, we evaluated high-intensity interval training and vitamin B12 + magnesium on women's migraine attacks and inflammatory status.
This study computed differential gene expression in migraine syndrome and the dimension network parameters visualized by software. Moreover, we proposed the functional mechanism and binding energy of essential micronutrients on macromolecules based on drug discovery. In this clinical trial, 60 cases were randomized to four groups, including applied high-intensity interval training (HIIT), cases consumed supplementation vitamin B12 and magnesium (Supp), cases applied high-intensity interval training, and consumed supplementation (HIIT + Supp), and migraine cases for 2months. Serum levels of calcitonin gene-related peptide (CGRP) were IRCT20170510033909N12. Approval Data 2021/06/02.
High-resolution MR vessel wall imaging (HRVWI) can characterise vessel wall pathology affecting intracranial circulation and helps in differentiating intracranial vasculopathies. The aim was to differentiate intracranial pathologies involving middle cerebral artery (MCA) in patients with ischemic stroke and characterise the high-risk plaques in intracranial atherosclerotic disease (ICAD) using HRVWI.
Patients with ischemic stroke with isolated MCA disease with ≥ 50% luminal narrowing by vascular imaging were enrolled within 2weeks of onset and underwent high-resolution (3T) intracranial vessel wall imaging (VWI). The pattern of vessel wall thickening, high signal on T1-weighted images, juxtaluminal hyperintensity, pattern and grade of enhancement were studied. The TOAST classification before and after HRVWI and the correlation of the recurrence of ischemic events at 3months with imaging characteristics were analysed.
Of the 36 patients, the mean age was 49.53 ± 15.61years. After luminal imaging, by TOAST classification, 12 of 36 patients had stroke of undetermined aetiology. After vessel wall imaging, lesions in MCA were analysed. Of them, 23 patients had ICAD, 8 had vasculitis, and 2 had partially occlusive thrombus in MCA. The ability of HRVWI to bring a change in diagnosis was significant (p = 0.031). Of the 23 patients with ICAD, 12 patients had recurrent strokes within 3months. The presence of grade 2 contrast enhancement (p = 0.02) and type 2 wall thickening (p = 0.03) showed a statistically significant association with recurrent ischemic events.
High-resolution MRVWI can help in identifying the aetiology of stroke. The HRVWI characteristics in ICAD can help in risk stratification.

Pilocytic astrocytoma (PA) is rare in adults, and only limited knowledge on the clinical course and prognosis has been available. The combination of clinical information and comprehensive imaging parameters could be used for accurate prognostic stratification in adult PA patients. This study was conducted to predict the prognostic factors from clinical information and conventional magnetic resonance imaging (MRI) features in adult PAs.
A total of 56 adult PA patients were enrolled in the institutional cohort. Clinical characteristics including age, sex, anaplastic PA, presence of neurofibromatosis type 1, Karnofsky performance status, extent of resection, and postoperative treatment were collected. MRI characteristics including major axis length, tumor location, presence of the typical 'cystic mass with enhancing mural nodule appearance', proportion of enhancing tumor, the proportion of edema, conspicuity of the nonenhancing margin, and presence of a cyst were evaluated. Univariable and multivariable Cox proportional hazard modeling were performed.
The 5-year progression-free survival (PFS) and overall survival (OS) rates were 83.9% and 91.l%, respectively. On univariable analysis, older age, larger proportion of edema, and poor definition of nonenhancing margin were predictors of shorter PFS and OS, respectively (all Ps < .05). On multivariable analysis, older age (hazard ratio [HR] = 1.04, P = .014; HR = 1.14, P = .030) and poor definition of nonenhancing margin (HR = 3.66, P = .027; HR = 24.30, P = .024) were independent variables for shorter PFS and OS, respectively.
Age and the margin of the nonenhancing part of the tumor may be useful biomarkers for predicting the outcome in adultPAs.

The aim of the study was to compare the parameters of blood flow in glioblastomas and primary central nervous system lymphomas (PCNSLs), measured by pseudo-continuous arterial spin labeling MRI (3D PCASL), and to determine the informativeness of this method in the differential diagnosis between these lesions.
The study included MRI data of 139 patients with PCNSL (n = 21) and glioblastomas (n = 118), performed in the Burdenko Neurosurgical Center. No patients received chemotherapy, hormone therapy, or radiation therapy prior to MRI. On the 3D PCASL perfusion map, the absolute and normalized values of tumor blood flow were calculated in the glioblastoma and PCNSL groups (maxTBFmean and nTBF).
MaxTBFmean and nTBF in the glioblastoma group were significantly higher than those in the PCNSL group 168.9ml/100g/min versus 65.6 and 9.3 versus 3.7, respectively (p < 0.001). Arterial spin labeling perfusion had high sensitivity (86% for maxTBFmean, 95% for nTBF) and specificity (77% for maxTBFmean, 73% for nTBF) in the differential diagnosis between PCNSL and glioblastomas. Blood flow thresholds were 98.9ml/100g/min using absolute blood flow values and 6.1 using normalized values, AUC > 0.88.
The inclusion of 3D PCASL in the standard MRI protocol can increase the specificity of the differential diagnosis between glioblastomas and PCNSL.

Innate immune components participate in obesity-induced inflammation, which can contribute to endocrine dysfunction during metabolic diseases. I-191 However, the chronological activation of specific immune proteins such as Nucleotide-binding oligomerization domain-containing protein 1 (NOD1) and relevance to cellular crosstalk during the progression of obesity-associated insulin resistance (IR) is not known.
The NOD1 signaling in various insulin-sensitive metabolic tissues during the progression of diet-insulin resistance was assessed in C57BL/6J mice fed with 60% high-fat diet (HFD) for 4, 8, 12, and 16 weeks. Intestinal permeability was measured using FITC-dextran. NOD1 activating potential was analyzed using HEK-Blue mNOD1 cells.
HFD-fed mice showed progressive induction of glucose intolerance and impairment of insulin signaling in key metabolic tissues. We found a time-dependent increase in intestinal permeability coupled with transport and accumulation of NOD1 activating ligand in the serum of HFD-fed mice. We also observed a progressive accumulation of γ-D-glutamyl-meso-diaminopimelic acid (DAP), a microbial peptidoglycan ligand known to activate NOD1, in serum samples of the HFD-fed mice. There was also a progressive increase in transcripts levels of NOD1 in bone marrow-derived macrophages during HFD-feeding. In addition, skeletal muscle, adipose and liver, the key insulin sensitive metabolic tissues also had a time-dependent increase in transcripts of NOD1 and Rip2 and a corresponding activation of pro-inflammatory responses in these tissues.
These data highlight the correlation of inflammation and insulin resistance to NOD1 activation in the bone marrow derived macrophages and insulin responsive metabolic tissues during high fat diet feeding in mice.

Distinguishing follicular thyroid carcinoma (FTC) from follicular thyroid adenoma (FTA) before surgery is inherently challenging owing to the lack of malignant features on ultrasound, poor sensitivity of fine-needle biopsy, and the absence of definitive markers. We investigated whether thyroglobulin (Tg), anti-thyroglobulin antibody (TgAb), thyroid peroxidase antibodies (TPOAb), and thyroid stimulating hormone (TSH) can help differentiate FTC from FTA.
Data pertaining to 319 patients with follicular neoplasms were retrospectively analyzed. We compared the serum markers between patients with confirmed FTC and FTA. We also analyzed the prevalence of FTC in different subgroups of patients based on serum marker levels.
TgAb was a risk factor for FTC. Compared to TgAb ≤11.68 IU/mL group, the odds ratio (OR) for FTC in TgAb 11.69-30.50 IU/mL group and TgAb >30.50 IU/mL group were 2.206 (1.114-4.369, P = 0.023) and 3.247 (1.684-6.260, P < 0.001), respectively. The prevalence of malignancy in TgAb >30.50 IU/mL group was significantly higher than in the TgAb ≤11.68 IU/mL group (32.9 vs. 13.1%, P = 0.001). In patients with TgAb (-) status, Tg was another risk factor for FTC. Compared to Tg ≤38.51 ng/mL group, OR of Tg >434.60 ng/mL group was 3.836 (1.625-9.058, P = 0.002); the prevalence of malignancy in the Tg >434.60 ng/mL group was 47.2% and higher than other groups.
TgAb and Tg levels may be useful markers for preoperative differential diagnosis of follicular neoplasms. Higher TgAb and Tg levels were associated with greater malignant risk. Thus, we should be cautious of preoperative TgAb and Tg in follicular neoplasms.

Knowledge regarding risk factors for pain in the long term after surgery for breast cancer may be of great value in preventing this prevalent and debilitating side effect. Despite the biopsychosocial nature of pain, the predictive value of both pre- and postoperative biopsychosocial functioning for long-term pain intensity and pain-related disability has not yet been studied.
One hundred sixty-six women planned for unilateral breast cancer surgery were included in this prospective cohort study. Pre- and postoperative outcomes related to pain, psychosocial, and somatosensory functioning (questionnaires and quantitative sensory testing) were evaluated as risk factors for pain intensity (visual analog scale) and pain-related disability (pain disability index) 1year after surgery for breast cancer. Both bivariable and stepwise linear regression analyses were performed.
The most consistent biopsychosocial risk factors were symptoms related to altered central somatosensory functioning (central sensitization inventory), psychological symptoms, and social support (psychological symptoms and support subscale of McGill Quality of Life Questionnaire).
