Defining circadian trouble in neurodegenerative disorders

The results support the hypothesis that mechanoreceptors located within the tooth contribute to vibrotactile tooth sensations and that mechanosensory information from both periodontal ligament and intradental mechanoreceptors facilitates the accurate assessment of food textures during mastication.

DMAMCL order It is largely recognized and demonstrated that early detection represents the first strategy to follow in the fight against cancer. The effectiveness of mammography screening for early breast cancer detection has been proven in several surveys and studies over the last three decades. The estimation of the Mean Glandular Dose (MGD) is important to understand the radiation-associated risk from breast x-ray imaging exams. It continues to be the subject of numerous studies and debates, since its accuracy is directly related to risk estimation and for optimizing breast cancer screening programs. This manuscript reviews the main dosimetry formalisms used to estimate the MGD in mammography and to understand the continuing efforts to reduce the absorbed dose over the last forty years. The dosimetry protocols were formulated initially for mammography. Digital breast tomosynthesis (DBT) either in conjunction with synthesized digital mammogram (SDM) or with digital mammography (DM), is routinely used in many breast cancer screening programs and consequently the dosimetry protocols were extended for these techniques.
Transcriptome-wide analysis is powerful in studying systemic RNA changes following environmental exposures. However, impacts of ozone inhalation on circulating transcriptome have not yet been examined.
To explore the impact of acute ozone exposure on circulating transcriptome using RNA sequencing (RNA-seq).
We recruited 32 healthy young adults in a randomized, crossover, controlled exposure trial. Each participant completed two 2-h exposure sessions of ozone (200ppb) and clean air, respectively. Blood samples were collected at the end of each session and were used for RNA-seq. The differentially expressed genes associated with ozone exposure were assessed using Bayesian adjusted statistics from linear models in the limma R package.
A total of 29 participants finished this trial and donated their blood samples for transcriptome analysis. The average concentration of ozone was 7.8±2.6ppb under clean air and 201.1±1.7ppb under ozone exposure session. A total of 1899 genes were significantly changed (1067dozens of biological processes and pathways, providing novel biological insights into the systemic health effects of ozone.Distributions of brain H3 histamine receptors in regions of the prefrontal cortex were studied by assessing regional binding densities for [3 H](R)α-methylhistamine in coronal brain slices of normal rats and rats with genetically determined absence and/or audiogenic epilepsies. The three groups of epileptic rats displayed widespread significant decreases in H3 histamine receptor binding densities. A 20-25% decline was seen in the rostral aspects of the lateral prefrontal cortex, namely the granular, dysgranular, and dorsal agranular insular regions. The reduction was not specific for the epilepsy types. The same was observed in the rostral part of the primary cingulate cortex and the secondary midcingulate cortex. On borders of this core effect, several seizure-type specific declines were seen. Namely, the infralimbic, prelimbic and posterior agranular insular cortices demonstrated absence-epilepsy related reductions in the H3 histamine receptor binding densities. A decrease related to audiogenic seizures was noted in the rostral part of the piriform cortex. The pattern of widespread and seizure-type unspecific decline in H3 histamine receptor binding densities points to a common part of brain loops underlying generalized convulsive and non-convulsive types of epilepsy. It also might hint at putative seizure-related changes in the release of histamine from specific fibers innervating the prefrontal area.Cardiovascular alterations are frequently related to epilepsy in both clinical and experimental models, and have been hypothesized as a potential contributor to sudden unexpected death in epilepsy (SUDEP). Further, the frequency of generalized tonic-clonic seizures (GTCS) is a primary risk factor for SUDEP. Therefore, we aimed to evaluate the vascular response of rats subjected to the electrical amygdala kindling model of epilepsy. Male Wistar rats were randomly distributed into the following groups without seizures (sham, n = 8), 5 GTCS (5 S, n = 5), and 10 GTCS (10 S, n = 6). One day after the last seizure, the rats were euthanized, and the thoracic aorta rings with (E+) and without (E-) endothelium were used to evaluate vascular reactivity ex vivo using the organ bath system. The maximum response to acetylcholine-induced vasorelaxation in the E+ aortic ring was lower in the 5 S group than in the sham and 10 S groups. A reduced concentration of sodium nitroprusside was required to induce vasorelaxation in the E- aortic rings. These results suggest an impairment in endothelial function and alterations in the nitric oxide (NO) pathway. In conclusion, epilepsy altered the vasorelaxation of the aortic rings and the number of seizures influenced these alterations; therefore, an analysis of endothelial function in patients with a high risk of SUDEP may be beneficial.
Epilepsy is a chronic disorder that affects all domains of daily living. Especially, in the case of drug resistance, it is usually associated with impairment of quality of life (QOL). The opportunity to self-express is crucial for maintaining mental health. Therefore, many non-pharmaceutical interventions have been utilized to relieve psychiatric symptoms, such as fear, anxiety, and depression in persons with epilepsy. In this study, we aimed to investigate the effect of the occupational therapy program with drama activities (ODTA) on the QOL of patients with epilepsy.
In total, 15 patients with epilepsy from the region of Thrace, Greece, were enrolled in a 3-month OTDA program focusing on the relief of anxiety symptoms and self-regulation. Each patient's QOL was measured using the Quality of Life in Epilepsy Inventory (QOLIE-31) mean scores. The reliability change index was calculated and the Wilcoxon paired test was used to determine QOL changes post-intervention compared to pre-intervention.
Statistically significant improvements were observed in fear of having a seizure (p =.004), overall quality (p =.001), emotional well-being (p =.004), energy fatigue (p =.014), and total QOLIE (p =.001) score after the intervention. The changes in the QOLIE score were more prominent among female individuals (male vs female p =.028 vs p =.008).
This study highlights the importance of providing an ODTA program in patients with epilepsy and proposes its broader combined application as a complementary intervention in such patients.

The objective was to report the outcomes of surgical management of cholesteatoma in Down Syndrome (DS) children and to determine the prevalence of cholesteatoma in DS children at three academic tertiary care centers.
A retrospective chart review was performed of all DS children diagnosed with cholesteatoma from three tertiary care academic centers. Demographic data, comorbidities, imaging findings, surgical management, and pre- and postoperative pure tone averages were collected.
The prevalence of cholesteatoma in DS patients at these three institutions was calculated to be 8/802 (0.998%), 4/448 (0.893%), and 4/1016 (0.394%), with an average prevalence of 0.762%. Of the 16 patients with cholesteatoma identified, the average age of diagnosis was 10.8 years, and 5/16 (31%) had at least three sets of pressure equalizing tubes (PETs) placed. Of the 13 patients with preoperative CTs, 4/13 (30.8%) had blunting of the scutum, 4/13 (30.8%) had tegmen involvement, 1/13 (7.7%) had erosion of the semicircular cana of patients, and ossicular erosion seen in more than half the patients. A CWU procedure can be successful in managing DS patients with cholesteatoma when consistent long term follow-up is planned. Close monitoring and a high index of suspicion for cholesteatoma are essential to prevent delays in diagnosis and treatment of DS patients with a history of multiple sets of PET placement.Biomechanical trajectories generally embody amplitude and temporal effects, but these effects are often analyzed separately. Here we demonstrate how amplitude-phase separation techniques from the statistics literature can be used to simultaneously analyze both. The approach hinges on nonlinear registration, which temporally warps trajectories to minimize timing effects, and the resulting optimal time warps can be combined with the resulting amplitudes in a simultaneous test. We first analyzed two simulated datasets with controlled amplitude and temporal effects to demonstrate how amplitude-timing separation can avoid incorrect conclusions from common amplitude-only hypothesis testing. We then analyzed two experimental datasets, demonstrating how amplitude-phase separation can yield unique perspectives on the relative contributions of amplitude and timing effects embodied in biomechanical trajectories. Last, we show that the proposed approach can be sensitive to procedural and parameter specifics, so we recommend that these sensitivities should be explored and reported.
The COX/PGE2 pathway is widely involved in the development of tumors and the regulation of tumor immune cells such as T cells, NK cells and DCs. However, little information is available on the single nucleotide polymorphisms (SNPs) of COX/PGE2 pathway-related genes in patients with lung cancer.
Seven SNPs of the PTGS2, PTGER2 and PTGIS genes were genotyped in a case-control cohort including 600 lung cancer cases and 600 controls using the MassARRAY platform.
The minor alleles of PTGS2-rs4648298, PTGS2-rs2745557, PTGER2-rs2075797 and PTGIS-rs6125671 were all risk alleles that led to a different degree of elevated lung cancer risk (p<0.001). The rs4648298-TC/CC, rs2745557-GA/AA, rs2075797-CG/GG and rs6125671-TC/CC genotypes were markedly associated with an elevated risk of lung cancer (p<0.0001). Moreover, genetic model results showed that PTGS2-rs4648298 was correlated with a 4.91-, 6.90- and 4.21-fold increased risk of lung cancer under dominant, recessive and log-additive models, respectively (p<0.0001). Similarly, PTGS2-rs2745557, PTGER2-rs2075797 and PTGIS-rs6125671 were also related to an elevated risk of the disease under the three genetic models (p<0.001). In addition, stratification analysis based on smoking status and pathological types showed that these four SNPs were associated with the risk of lung cancer in both smokers and nonsmokers and in all three pathological types, including adenocarcinoma, squamous cell carcinoma, and small cell lung cancer (p<0.014).
These results contribute to a better understanding of the pathogenesis of lung cancer and provide new clues for the early detection and personalized treatment of the disease.
