There is a paucity of evidence and consensus on exactly how to carry out the detoxification process. To examine the effect of a greater occipital nerve block (GONB) in the detoxification process, we conducted an open-label, parallel, randomized, controlled clinical trial.

In order to conduct this study, 54 medication-overuse headache (MOH) patients were recruited and allocated randomly to group A (n = 27) or B (n = 27). In both groups, patients underwent detoxification processes without any acute migraine medication or analgesics. During the run-in period, all patients in both groups received the same education, managed by a neurologist and nutritionist. All patients were offered maximally 300 mL of promethazine syrup (5 mg/5 mL) to be taken 10 mg every 8 h during the first 10 days of the study. A 2-mL syringe containing 1 mL of lidocaine 2% and 1 mL of triamcinolone 40 mg/mL was prepared for each patient of group A for conducting GONB. Characteristics of headache attacks, including headache severity, frequency, and duration, were assessed at baseline and after 3 months of intervention.

Twenty-six patients in group A (96.3%) and twenty-three in group B (85.2%) completed detoxification, and were thus cured of MOH (P = 0.351). The present study revealed that GONB with local anesthetic and triamcinolone significantly improved the characteristics of headache, including frequency (- 13.66 in group A and - 7.55 in group B), duration (- 7.92 in group A and - 5.88 in group B), and severity (- 3.44 in group A vs. - 1.33 in group B) in group A compared to control (all P value < 0.05).

Although both detoxification programs were effective, detoxification with GONB resulted in better outcomes.

Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) is a rare affection of the peripheral nervous system. Its diagnostic criteria have evolved since 1975. The aim of our work is to study the epidemiological, clinical, and paraclinical aspects of CIDP.

We conducted a retrospective study of 28 CIDP patients of the neurology department of the military hospital of Tunis between January 2000 and December 2017. All these patients met the European Federation of Neurological Societies/Peripheral Nerve Society(EFNS/PNS)2010 diagnostic criteria for definite CIDP.

The average age was 50years with a gender ratio of 1.57. We found sensitivomotor symptoms in 66% of patients. Neurological assessment showed a proximal and distal motor weakness in 50% of cases, the involvement of superficial and deep sensory systems in 44% of patients with a generalized areflexia in all patients. Median Inflammatory Neuropthy Cause and Treatment (INCAT) score was 7. Concerning electrophysiology, all our patients met the EFNS/EPS 2010 diagnostic criteria for a definite CIDP. Screening for concurrent pathologies was positive in 11 patients. On the therapeutic side, there was no superiority of intravenous immunoglobin compared with pulsed methylprednisolone. Oral steroids were used as backup in about 50% of patients. There were good outcomes in 72% of patients who improved very well after treatment.

CIDP is a rare and polymorphic disorder with a variety of concurrent pathologies. Our study is the first study in Tunisia and in Maghreb countries which included the most big series of patients. Our results were similar to literature. A multicentral study would be better profitable.

Ascertain and quantify abnormality of the melanopsin-derived portion of the pupillary light reflex (PLR) in patients with Parkinson's disease (PD) and parkinsonism features based on a statistical predictive modeling strategy for PLR classification.

Exploratory cohort analysis of pupillary kinetics in non-disease controls, PD subjects, and subjects with parkinsonism features using chromatic pupillometry. Receiver operating characteristic (ROC) curve interpretation of pupillary changes consistent with abnormality of intrinsically photosensitive retinal ganglion cells (ipRGCs) was employed using a thresholding algorithm to discriminate pupillary abnormality between study groups.

Twenty-eight subjects were enrolled, including 17 PD subjects (age range 64-85, mean 70.65) and nine controls (age range 48-95, mean 63.89). Two subjects were described as demonstrating parkinsonism symptoms due to presumed Lewy body dementia and motor system atrophy (MSA) respectively. On aggregate analysis, PD subjects demonstrated abnormal but variable pupillary dynamics suggestive of ipRGC abnormality. Subjects with parkinsonism features did not demonstrate pupillary changes consistent with ipRGC abnormality. There was no relationship between levodopa equivalent dosage or PD severity and ipRGC abnormality. The pupillary test sensitivity in predicting PD was 0.75 and likelihood ratio was 1.2.

ipRGC deficit is demonstrated in PD subjects; however, the degree and constancy of abnormality appear variable.

Glioma is a common brain malignancy, and the purpose of this study is to investigate the function of LINC02308 in glioma.

The differentially expressed lncRNAs were screened by microarray. The expression of LINC02308 in glioma tissues and cells was evaluated. The interaction among LINC02308, miR-30e-3p, and TM4SF1 was determined. Cell proliferation and apoptosis were evaluated. The expression of mTOR/AKT-signaling and apoptosis-related markers was detected by Western blot. A xenograft tumor mouse model was constructed to investigate the roles of LINC02308.

LINC02308 was significantly overexpressed in glioma, and a high LINC02308 level was correlated with a poor prognosis. LINC02308 silencing markedly inhibited proliferation and reduced apoptosis of glioma cells and also suppressed tumor growth in the xenograft tumor mouse model. Finally, we demonstrated that LINC02308 played its oncogenic role through binding to miR-30e-3p so as to relieve miR-30e-3p-induced suppression of TM4SF1.

LINC02308 promoted glioma tumorigenesis as a sponge of miR-30e-3p to upregulate TM4SF1 and activate AKT/mTOR pathway. Graphical Abstract Hypothesis diagram illustrates the function and mechanism of LINC02308 in glioma. A schematic representation of the functional mechanism of LINC02308 in glioma.

The Ca2+ and voltage gated members form a subfamily that play a variety of roles in both excitable and non-excitable cells and are further classified on the basis of their single channel conductance to form the small conductance (SK), intermediate conductance (IK) and big conductance (BK) K+ channels.In this chapter, we will focus on the mechanisms underlying the gating of BK channels, whose function is modified in different tissues by different splice variants as well as the expanding array of regulatory accessory subunits including β, γ and LINGO subunits. We will examine how BK channels are modified by these regulatory subunits and describe how the channel gating is altered by voltage and Ca2+ whilst setting this in context with the recently published structures of the BK channel. read more Finally, we will discuss how BK and other calcium-activated channels are modulated by novel ion channel modulators and describe some of the challenges associated with trying to develop compounds with sufficient efficacy, potency and selectivity to be of therapeutic benefit.G protein-coupled taste receptors and their downstream signaling elements, including Gnat3 (also known as α-gustducin) and TrpM5, were first identified in taste bud cells. Subsequent studies, however, revealed that some cells in nongustatory tissues also express taste receptors and/or their signaling elements. These nongustatory-tissue-expressed taste receptors and signaling elements play important roles in a number of physiological processes, including metabolism and immune responses. Special populations of cells expressing taste signaling elements in nongustatory tissues have been described as solitary chemosensory cells (SCCs) and tuft cells, mainly based on their morphological features and their expression of taste signaling elements as a critical molecular signature. These cells are typically scattered in barrier epithelial tissues, and their functions were largely unknown until recently. Emerging evidence shows that SCCs and tuft cells play important roles in immune responses to microbes and parasites. Additionally, certain immune cells also express taste receptors or taste signaling elements, suggesting a direct link between chemosensation and immune function. In this chapter, we highlight our current understanding of the functional roles of these "taste-like" cells and taste signaling pathways in different tissues, focusing on their activities in immune regulation.The structure of the human kappa opioid receptor (KOR) in complex with the long-acting antagonist JDTic was solved crystallographically in 2012 and, along with structures of other opioid receptors, revolutionized our understanding of opioid system function and pharmacology. More recently, active state KOR structure was also determined, giving important insights into activation mechanisms of the receptor. In this review, we will discuss how the understanding of atomistic structures of KOR established a key platform for deciphering details of subtype and functional selectivity of KOR-targeting ligands and for discovery of new chemical probes with potentially beneficial pharmacological profiles.Stream bioassessment using benthic macroinvertebrate assemblages is widely implemented by regulatory agencies, yet a critical question regarding spatial autocorrelation and sample independence remains How much of a stream network does a point sample represent? Macroinvertebrate assemblages vary along a longitudinal gradient, likely due to a combination of natural and anthropogenic factors that alter water physiochemistry and habitat. A better understanding of how these gradients affect macroinvertebrate assemblage variance could prevent spatial over- and under-sampling within bioassessment efforts. This project investigated longitudinal patterns (10 s of km) of macroinvertebrate assemblages in 14 Wisconsin streams. Spatial autocorrelation was assessed using Moran's I and other multivariate methods with an emphasis on estimating the distance at which assemblages no longer display spatial correlation. Within most streams, there was a linear, direct relationship between assemblage dissimilarity and longitudinal distance, with distance to independence (DTI) ranging from 1.
