The inhibition effect from the cosh-Gaussian modulated incoherent source on the defocusing effect is investigated theoretically in lensless ghost imaging (LGI) and ghost diffraction (LGD) systems. The corresponding numerical simulations are presented to show the influence of the cosh-Gaussian incoherent source on the defocusing effect in LGI and LGD. Compared with the widely used Gaussian incoherent source, it is shown that the defocusing effect in LGI and LGD can be greatly weakened by properly adjusting the modulation parameter ω of the cosh-Gaussian source...

The present study was aimed to isolate indigenous plant growth-promoting bacteria (PGPB) from Nanmangalam reserve forest, India and to analyze their positive impact on nursery plant species. In total, 160 isolates were obtained from different nitrogen-free Media (LGI, JMV, NFB). Amongst these, 12 isolates were shown positive for 5-8% of ammonia production nif H positive and then isolates were further tested for their plant growth-promoting (PGP) activity. Based on their PGP activity, nine isolates were selected, and applied in nurseries of twelve native plant species, along with organic manure and inorganic fertilizer...

PROBLEM: Infection during pregnancy can disrupt regulatory/effector immune system balance, resulting in adverse pregnancy and fetal-neonatal outcomes. Heme oxygenase-1 (HO-1) is a major regulatory enzyme in the immune system. We observed maternal immune response dysregulation during late gestational inflammation (LGI), which may be mediated by HO-1. Here, we extend these studies to examine the immune response of offspring. METHOD OF STUDY: Pregnant wild-type (Wt) and HO-1 heterozygote (Het) dams were treated with lipopolysaccharide (LPS) or vehicle at E15...

Limbic encephalitis (LE) is characterized by short-term memory loss, disorientation, agitation, seizures, and histopathological evidence of medial temporal lobe inflammation. Leucine-rich, glioma inactivated 1 (LGI-1) is an auto-antigen associated with LE. We report a 37-year-old male patient with LGI-1-related LE who presented with recurrent episodes of selective amnesia, seizure-like activity, confusion, and personality change. His symptoms were significantly improved with steroid therapy. Thorough differential diagnosis with consideration for autoimmune encephalitis should be in patients with presentation of symptoms, such as memory impairment, personality change and seizure-like activity, especially when other neurological diagnoses are excluded...

Background: Psychotic experiences (PEs) are considered part of an extended psychosis phenotype and are associated with an elevated risk of developing a psychotic disorder. Risk of transition increases with persistence of PEs, and this is thought to be modulated by genetic and environmental factors. However, it is unclear if persistence is associated with progressive schizophrenia-like changes in neuroanatomy. Methods: We examined cortical morphometry using MRI in 247 young adults, from a population-based cohort, assessed for the presence of PEs at ages 18 and 20...

Ingestion of low glycemic index (LGI) carbohydrate (CHO) before exercise induced less insulin response and higher fat oxidation than that of high GI (HGI) CHO during subsequent exercise. However, the effect on the subsequent postprandial lipid profile is still unclear. Therefore, the aim of this study was to investigate ingestion of CHO drinks with different GI using fructose and glucose before endurance exercise on the subsequent postprandial lipid profile. Eight healthy active males completed two experimental trials in randomized double-blind cross-over design...

In schizophrenia temporal cortical volume loss differs between patients presenting with persistent auditory verbal hallucinations (pAVH) in contrast to those without hallucinatory symptoms (nAVH). However, it is unknown whether this deficit reflects a neural signature of neurodevelopmental origin or if abnormal temporal cortical volume is reflective of factors which may be relevant at later stages of the disorder. Here, we tested the hypothesis that local gyrification index (LGI) in regions of the temporal cortex differs between patients with pAVH (n=10) and healthy controls (n=14), and that abnormal temporal LGI discriminates between pAVH and nAVH (n=10)...

Dietary supplementation with fermentable fiber suppresses adiposity and the associated parameters of metabolic syndrome. Microbiota-generated fiber-derived short-chain fatty acids (SCFAs) and free fatty acid receptors including GPR43 are thought to mediate these effects. We find that while fermentable (inulin), but not insoluble (cellulose), fiber markedly protected mice against high-fat diet (HFD)-induced metabolic syndrome, the effect was not significantly impaired by either inhibiting SCFA production or genetic ablation of GPR43...

BACKGROUND: Although the study of the neuroanatomical correlates of generalized anxiety disorder (GAD) is gaining increasing interest, up to now the cortical anatomy of GAD patients has been poorly investigated and still no data on cortical gyrification are available. The aim of the present study is to quantitatively examine the cortical morphology in patients with GAD compared with healthy controls (HC) using magnetic resonance imaging (MRI). To the best of our knowledge, this is the first study analyzing the gyrification patterns in GAD...

BACKGROUND: Leucine-rich glioma-inactivated (LGI) proteins play a critical role in synaptic transmission. Dysfunction of these genes and encoded proteins is associated with neurological disorders such as genetic epilepsy or autoimmune limbic encephalitis in animals and human. Familial spontaneous epileptic cats (FSECs) are the only feline strain and animal model of familial temporal lobe epilepsy. The seizure semiology of FSECs comprises recurrent limbic seizures with or without evolution into generalized epileptic seizures, while cats with antibodies against voltage-gated potassium channel complexed/LGI1 show limbic encephalitis and recurrent limbic seizures...

BACKGROUND: MicroRNAs (miRNAs) are small non-coding RNA molecules that can play an important role in several chronic metabolic conditions, including obesity. However, to date little is known about how they are regulated. Weight loss induced by surgical procedures has been effective at modulating specific circulating miRNAs, but the effect of energy-restricted diets with different macronutrient compositions on circulating miRNAs is not well understood. The objective of the present analysis was to explore the effect of three energy-restricted diets of different macronutrient composition and carbohydrate quality on plasma miRNA levels...

Resting heart rate (RHR) is associated with arterial stiffness, inflammation, and cardiovascular (CV) and all-cause mortality in the general population and in patients at high CV risk. We assessed the association of RHR with arterial stiffness and low-grade inflammation (LGI) in a cross-sectional study that included 101 women with systemic lupus erythematosus (SLE) without a history of CV disease or arrhythmia or who were under treatment that may cause bradycardia. Pulse wave velocity (PWV; a measure of arterial stiffness), RHR, and markers of LGI (ie, C-reactive protein, fibrinogen, erythrocyte sedimentation rate, insulin, and homeostatic model assessment index) were measured...

Trigeminal neuralgia (TN) is a chronic neuropathic pain disorder characterized by intense, lancinating attacks of facial pain. Increasing evidence suggests that TN is accompanied by abnormalities in brain morphology, white matter microstructure, and function. However, whether these abnormalities are linked or reflect independent etiologies remains unknown. Using multimodal magnetic resonance imaging data of 20 patients with TN and 21 healthy controls, we investigated cortical gyrification abnormalities, their relationships with abnormalities of the underlying white matter microstructure and gray matter morphology, as well as their functional significance in TN...

BACKGROUND: Markers of subclinical cardiac injury are elevated in individuals with type 2 diabetes mellitus (T2DM) compared to healthy individuals. Low glycemic index (LGI) diets may improve both diabetes and cardiovascular risk but their effects on cardiac injury and fibrosis have not been previously studied. To test the effect of a LGI diet on markers of subclinical cardiac injury and fibrosis, we assessed the effect of a LGI compared with a high-cereal fibre diet on high-sensitivity cardiac troponin I (hs-cTnI) and galectin-3 in otherwise healthy individuals with T2DM in an exploratory analysis of a completed randomized trial...

A stoichiometric displacement model for retention (SDM-R) of small solutes and proteins based on hydrophilic interaction chromatography (HILIC) was presented. A linear equation that related the logarithm of the capacity factor of the solute to the logarithm of the concentration of water in the mobile phase was derived. The stoichiometric displacement parameters, Z (the number of water molecules required to displace a solute from ligands) and lgI (containing a number of constants that relate to the affinity of solute to the ligands) could be obtained from the slope and the intercept of the linear plots of lgk' vs...

Ageing of the global population has become a public health concern with an important socio-economic dimension. Ageing is characterized by an increase in the concentration of inflammatory markers in the bloodstream, a phenomenon that has been termed "inflammageing". The inflammatory response is beneficial as an acute, transient reaction to harmful conditions, facilitating the defense, repair, turnover and adaptation of many tissues. However, chronic and low grade inflammation is likely to be detrimental for many tissues and for normal functions...

Alzheimer's disease (AD) is a neurological disorder that creates neurodegenerative changes at several structural and functional levels in human brain tissue. The fractal dimension (FD) is a quantitative parameter that characterizes the morphometric variability of the human brain. In this study, we investigate spherical harmonic-based FD (SHFD), thickness, and local gyrification index (LGI) to assess whether they identify cortical surface abnormalities toward the conversion to AD. We study 33 AD patients, 122 mild cognitive impairment (MCI) patients (50 MCI converters and 29 MCI nonconverters), and 32 healthy controls (HC)...

Lateral temporal lobe epilepsy (lTLE) is a rare condition characterized by auditory auras or receptive aphasia, negative MRI, and relatively benign evolution. With the low number of cases in the world, our objective was to analyze a cohort of sporadic cases with lTLE (slTLE), in order to investigate possible cerebral morphological alterations. Forty patients with lTLE (34.93±12.08years of age) and 38 healthy controls (CTRL, 34.55±9.08years of age) were enrolled from four tertiary Italian epilepsy centers, which provided brain MRI T1-weighted images following a standard protocol for patients with epilepsy...
