Identification and Classification of Bulk Paddy, Brown, and White Rice Cultivars with Colour Features Extraction using Image Analysis and Neural Network

Golpour I. , Parian J.A. , Chayjan R.A. (2014): Identification and classification of bulk paddy, brown, and white rice cultivars with colour features extraction using image analysis and neural network. Czech J. Food Sci., 32: 280–287. We identify five rice cultivars by mean of developing an image processing algorithm. After preprocessing operations, 36 colour features in RGB, HSI, HSV spaces were extracted from the images. These 36 colour features were used as inputs in back propagation neural network. The feature selection operations were performed using STEPDISC analysis method. The mean classification accuracy with 36 features for paddy, brown and white rice cultivars acquired 93.3, 98.8, and 100%, respectively. After the feature selection to classify paddy cultivars, 13 features were selected for this study. The highest mean classification accuracy (96.66%) was achieved with 13 features. With brown and white rice, 20 and 25 features acquired the highest mean classification accuracy (100%, for both of them). The optimised neural networks with two hidden layers and 36-6-5-5, 36-9-6-5, 36-6-6-5 topologies were obtained for the classification of paddy, brown, and white rice cultivars, respectively. These structures of neural network had the highest mean classification accuracy for bulk paddy, brown and white rice identification (98.8, 100, and 100%, respectively).
Spleen-Preserving Total Pancreatectomy With Conservation of the Spleen Vessels:: Operative Technique and Possible Indications

Conventional distal pancreatectomy (cDP) and total pancreatectomy (cTP) also involve removal of the spleen. The spleen, however, is an important organ in the immunologic defense of the host and is worthy of preservation if this can be safely achieved. We performed a spleen-preserving total pancreatectomy (SPTP), with good results, in a Caucasian woman, 66-year-old, affected by pancreatic metastases of renal clear cell carcinoma. This is the first report of a SPTP for pancreatic metastases to our knowledge, and we therefore wish to describe the surgical technique and to suggest the possible indications for this new technique.
[Transforming growth factor-beta can induce differentiation of hypertrophic chondrocytes into osteoblast-like cells in epiphyseal plate].

OBJECTIVE To investigate the effect of transforming growth factor-beta (TGF-beta) on the differentiation of hypertrophic chondrocytes in epiphyseal plate in order to understand its role in the mechanism of bone and cartilage formation. METHODS We observed the effect of TGF-beta in varied time and dosage on the differentiation of hypertrophic chondrocytes in embryonic chick femora which were cultured in serum-free medium, using histochemical staining to detect the expression of alkaline phosphatase (ALP) and immunohistochemical staining to detect the expression of type I collagen and fibronectin. RESULTS TGF-beta enabled the chondrocytes to express type I collagen and fibronectin, and it enhanced the expression of ALP in hypertrophic zone. Time-effect and dosage-effect relationships were observed. CONCLUSION TGF-beta can induce the differentiation of hypertrophic chondrocytes into osteoblast-like cells in epiphyseal plate of embryonic chick femora. The inducing effect might be closely related to time and dosage of TGF-beta.
Archaeal flagellin combines a bacterial type IV pilin domain with an Ig-like domain

Significance Bacterial motility has been studied for many years, but much less is known about the flagellar system in archaea that provides motility. We have determined the structure of a flagellar-like filament from an archaeon using cryo-EM and can show how it has evolved combining domains from two different protein families. The mechanical properties of the filament are now explained from a computational analysis of the atomic model that we have been able to build. These results provide insights into how motile systems can arise by convergent evolution. The bacterial flagellar apparatus, which involves ∼40 different proteins, has been a model system for understanding motility and chemotaxis. The bacterial flagellar filament, largely composed of a single protein, flagellin, has been a model for understanding protein assembly. This system has no homology to the eukaryotic flagellum, in which the filament alone, composed of a microtubule-based axoneme, contains more than 400 different proteins. The archaeal flagellar system is simpler still, in some cases having ∼13 different proteins with a single flagellar filament protein. The archaeal flagellar system has no homology to the bacterial one and must have arisen by convergent evolution. However, it has been understood that the N-terminal domain of the archaeal flagellin is a homolog of the N-terminal domain of bacterial type IV pilin, showing once again how proteins can be repurposed in evolution for different functions. Using cryo-EM, we have been able to generate a nearly complete atomic model for a flagellar-like filament of the archaeon Ignicoccus hospitalis from a reconstruction at ∼4-Å resolution. We can now show that the archaeal flagellar filament contains a β-sandwich, previously seen in the FlaF protein that forms the anchor for the archaeal flagellar filament. In contrast to the bacterial flagellar filament, where the outer globular domains make no contact with each other and are not necessary for either assembly or motility, the archaeal flagellin outer domains make extensive contacts with each other that largely determine the interesting mechanical properties of these filaments, allowing these filaments to flex.
Effect of balance Solution on the Peritoneal Membrane in Automated Peritoneal Dialysis

Interference of conventional peritoneal dialysis fluids (cPDFs) with peritoneal membrane cell functions may be attributed to the dialysis fluid's low pH, high glucose concentration, and/or the presence of glucose degradation products (GDPs), the last of which leads to higher levels of advanced glycation end-products (AGEs). It has been suggested that the peritoneal membrane might be better preserved by using biocompatible solutions, including cancer antigetn 125 (CA125). This prospective, open-label, multicentre, randomized, controlled, cross-over phase IV study compared the in vivo biocompatibility of a neutral-pH, low-GDP peritoneal dialysis (PD) solution (balance) with a cPDF in automated PD (APD) patients. Our study revealed a significantly increased appearance rate and concentration of CA125 in the peritoneal effluent of APD patients treated with the neutral-pH, low-GDP solution balance versus a conventional PD solution.
Incisional Hernia after Periacetabular Osteotomy

The incidence of incisional abdominal hernias, an unreported complication after a Bernese periacetabular osteotomy, was evaluated. Two cases of an incisional hernia above the iliac crest were detected in a series of 950 cases since 1984. Although the incidence has been small, risk factors may be obesity, weak abdominal muscle strength, or increased abdominal pressure attributable to chronic coughing or obstipation. The surgeon should recognize the importance of restoring continuity of the abdominal fascia in patients with such factors.
Perceptions of People with Psychological Problems: Effects of Seeking Counseling

The present experiment examined the effects of variations in psychological history and academic qualifications on impressions of college applicants. 94 male and 81 female undergraduates were led to believe that the applicant had previous psychological problems or had previous psychological problems and sought professional help, or they were given no information about psychological history. Subjects also were informed that the person had strong or weak academic credentials or they were given no academic data. Applicants with previous psychological problems were rated more favorably when they sought counseling than when they did not. Applicants for whom no psychological problems were indicated were rated most highly over-all on security and sociability whereas applicants who had problems and sought counseling were evaluated most favorably on competence and character. A main effect for academic credentials was also obtained: subjects generally rated applicants with strong credentials most highly. The over-all pattern of results supports previous research indicating that people are ambivalent about persons with psychological problems.
Pharmacological Activation of Kainate Receptors Drives Endocannabinoid Mobilization

Activation of both presynaptic metabotropic cannabinoid type 1 receptors (CB1s) and ionotropic kainate receptors (KARs) can efficiently modulate GABA release at many synapses of the CNS. The inhibitory effect of kainic acid (KA) has been ascribed to metabotropic actions, and KAR-induced release of secondary neuromodulatory agents may partly mediate these actions. Here, we investigated the involvement of the endocannabinoid system in the modulation of GABAergic synaptic transmission by pharmacological activation of KARs with KA in CA1 pyramidal neurons of the mouse hippocampus. We show that the depression of GABAergic synaptic transmission induced by KA (3 μm) is strongly inhibited by the simultaneous blockade of CB1 and GABAB receptors with SR141716A (5 μm) and CGP55845 (5 μm), respectively. KA induces a calcium-dependent mobilization of the endocannabinoid anandamide (AEA) by activation of GluK2-containing KARs in postsynaptic pyramidal neurons. Consistently, the effect of KA is prolonged by the inhibitor of AEA degradation URB597 (1 μm) in a CB1-dependent manner, but it is not altered by blockade of degradation or synthesis of the other main endocannabinoid 2-arachidonoylglycerol (2AG). Hence, our work reveals that the pharmacological activation of KARs leads to the stimulation of secondary metabotropic signaling systems. In addition, these data further underline the profound mechanistic differences between exogenous and endogenous activation of KARs in the hippocampus.
Perpendicular exchange bias and magnetic anisotropy in CoO/permalloy multilayers

For permalloy/CoO multilayers, after perpendicular field cooling, perpendicular exchange bias has been observed below room temperature. For out-of-plane hysteresis loops, the exchange field and the coercivity at fixed temperatures are proportional to l/t F M and l/t 3 / 2 FM (t F M =permalloy layer thickness), respectively. At the same time, the remanent ratio increases with decreasing t F M . The induced effective uniaxial anisotropy changes as a linear function of l/t F M , as a symbol of an interface anisotropy. The interface anisotropic energy increases with decreasing temperatures. For samples with small t F M , perpendicular anisotropy films can be established at low temperature. The established perpendicular magnetic anisotropy and its remarkable temperature dependence might facilitate perpendicular magnetic recording and magneto-optical storage techniques.
Transcriptomic Response of Resistant (PI613981–Malus sieversii) and Susceptible (“Royal Gala”) Genotypes of Apple to Blue Mold (Penicillium expansum) Infection

Malus sieversii from Central Asia is a progenitor of the modern domesticated apple (Malus × domestica). Several accessions of M. sieversii are highly resistant to the postharvest pathogen Penicillium expansum. A previous study identified the qM–Pe3.1 QTL on LG3 for resistance to P. expansum in the mapping population GMAL4593, developed using the resistant accession, M. sieversii –PI613981, and the susceptible cultivar “Royal Gala” (RG) (M. domestica), as parents. The goal of the present study was to characterize the transcriptomic response of susceptible RG and resistant PI613981 apple fruit to wounding and inoculation with P. expansum using RNA–Seq. Transcriptomic analyses 0–48 h post inoculation suggest a higher basal level of resistance and a more rapid and intense defense response to wounding and wounding plus inoculation with P. expansum in M. sieversii –PI613981 than in RG. Functional analysis showed that ethylene–related genes and genes involved in “jasmonate” and “MYB–domain transcription factor family” were over–represented in the resistant genotype. It is suggested that the more rapid response in the resistant genotype (Malus sieversii–PI613981) plays a major role in the resistance response. At least twenty DEGs were mapped to the qM–Pe3.1 QTL (M × d v.1: 26,848,396–28,424,055) on LG3, and represent potential candidate genes responsible for the observed resistance QTL in M. sieversii–PI613981. RT–qPCR of several of these genes was used to validate the RNA–Seq data and to confirm their higher expression in MS0.
[Hypovitaminosis D in Children with Hashimotos Thyroiditis].

BACKGROUND Vitamin D deficiency or insufficiency may play a role in the pathogenesis of certain autoimmune diseases. AIM To measure vitamin D levels in children with Hashimotos thyroiditis (HT) (either with subclinical or marked hypothyroidism) and in healthy controls. MATERIAL AND METHODS We included 68 children with HT aged 12 ± 4 years (39 females) from a pediatric outpatient clinic and 68 healthy children aged 10 ± 4 years (37 females). Calcium metabolism parameters, thyroid function tests and anti-thyroid peroxidase (anti-TPO), anti-thyroglobulin (anti-TG) and 25 hydroxy vitamin D (25OHD) levels were measured. RESULTS Patients were older than controls but well matched by gender distribution. Mean 25OHD levels were significantly lower in HT patients than controls (16.8 ± 9.3 and 24.1 ± 9.4 ng/mL respectively, P < 0.01). Frequency of vitamin D deficiency was 76 and 35% in HT patients and controls, respectively (P < 0.001). CONCLUSIONS Vitamin D deficiency is more common in children with HT than healthy controls.
Anti-heparan Sulfate Peptides That Block Herpes Simplex Virus Infection in Vivo*

Heparan sulfate (HS) and its highly modified form, 3-O-sulfated heparan sulfate (3-OS HS), contribute strongly to herpes simplex virus type-1 (HSV-1) infection in vitro. Here we report results from a random M13-phage display library screening to isolate 12-mer peptides that bind specifically to HS, 3-OS HS, and block HSV-1 entry. The screening identified representative candidates from two-different groups of anti-HS peptides with high positive charge densities. Group 1, represented by G1 peptide (LRSRTKIIRIRH), belongs to a class with alternating charges (XRXRXKXXRXRX), and group 2, represented by G2 peptide (MPRRRRIRRRQK), shows repetitive charges (XXRRRRXRRRXK). Viral entry and glycoprotein D binding assays together with fluorescent microscopy data indicated that both G1 and G2 were potent in blocking HSV-1 entry into primary cultures of human corneal fibroblasts and CHO-K1 cells transiently expressing different glycoprotein D receptors. Interestingly, G2 peptide isolated against 3-OS HS displayed wider ability to inhibit entry of clinically relevant strains of HSV-1 and some divergent members of herpesvirus family including cytomegalovirus and human herpesvirus-8. To identify functional residues within G1 and G2, we performed point mutations and alanine-scanning mutagenesis. Several arginine and a lysine residues were needed for anti-HSV-1 activity, suggesting the importance of the positively charged residues in virus-cell binding and virus-induced membrane fusion. In vivo administration of G1 or G2 peptide as a prophylactic eye drop completely blocked HSV-1 spread in the mouse cornea as evident by immunohistochemistry. This result also highlights an in vivo significance of HS and 3-OS HS during ocular herpes infection.
A framework for analyzing digital volunteer contributions in emergent crisis response efforts

Advances in information, communication, and computational technologies allow digital volunteer networks formed by concerned publics across the globe to contribute to an effective response to disasters and crises. Digital volunteer networks are event-centric and emergent networks. Currently, the literature is sharply growing in the fields of communication, computer science, emergency management, and geography. This article aims to assess the current status of the literature and suggest a comprehensive conceptual framework of digital volunteer networks in response to disasters and crises. This framework is based on a traditional input–process–output model consisting of three dimensions: the disaster and crisis context, a voluntary response process, and outputs and outcomes. We also discuss challenges of digital volunteer networks for crisis response. This article is expected to contribute to the development of related theories and hypotheses and practical strategies for managing digital volunteer networks.
Improved outcome with delayed intensification for children with acute lymphoblastic leukemia and intermediate presenting features: a Childrens Cancer Group phase III trial.

PURPOSE The Berlin-Frankfurt-Munster (BFM) 76/79 trial of acute lymphoblastic leukemia (ALL) in children produced impressive disease-free survival (DFS) rates with a protocol that began with 8 weeks of intensive therapy, followed by 8 weeks of maintenance therapy, and then another 6 weeks of intensive treatment. The current study was conducted to determine the relative contributions of each of these periods of intense therapy on the DFS rates of ALL patients with intermediate presenting features. In addition, due to concerns regarding the toxicity of CNS irradiation, we compared cranial irradiation (CXRT) with intrathecal methotrexate (IT MTX) administered during induction and consolidation to IT MTX during all phases of the treatment program. PATIENTS AND METHODS Between May 1983 and April 1989, more than 1,600 children with ALL and intermediate presenting features, as defined by the Childrens Cancer Group (CCG), were entered into a randomized trial that tested four systemic therapy regimens and two CNS programs. RESULTS The results with a median follow-up of 57 months show that systemic regimens with a delayed intensification (Delint) phase of therapy had a 5-year event-free survival (EFS) rate of 73% compared with the control regimen EFS rate of 61% (p = .006). For children less than 10 years of age, standard three-drug induction and Delint produced a 77% 5-year EFS. IT MTX during all phases of therapy provided CNS protection comparable to the CXRT regimen in children less than 10 years of age. Children 10 years of age or older appear to have a better EFS rate with intensive induction, Delint, and CXRT. CONCLUSION Delint improves the EFS rate of children with ALL and intermediate presenting features. Maintenance IT MTX can be safely substituted for CXRT for presymptomatic CNS therapy in children with intermediate-risk characteristics less than 10 years of age.
Modulating Endoplasmic Reticulum-Golgi Cargo Receptors for Improving Secretion of Carrier-Fused Heterologous Proteins in the Filamentous Fungus Aspergillus oryzae

ABSTRACT Filamentous fungi are excellent hosts for industrial protein production due to their superior secretory capacity; however, the yield of heterologous eukaryotic proteins is generally lower than that of fungal or endogenous proteins. Although activating protein folding machinery in the endoplasmic reticulum (ER) improves the yield, the importance of intracellular transport machinery for heterologous protein secretion is poorly understood. Here, using Aspergillus oryzae as a model filamentous fungus, we studied the involvement of two putative lectin-like cargo receptors, A. oryzae Vip36 (AoVip36) and AoEmp47, in the secretion of heterologous proteins expressed in fusion with the endogenous enzyme α-amylase as the carrier. Fluorescence microscopy revealed that mDsRed-tagged AoVip36 localized in the Golgi compartment, whereas AoEmp47 showed localization in both the ER and the Golgi compartment. Deletion of AoVip36 and AoEmp47 improved heterologous protein secretion, but only AoVip36 deletion had a negative effect on the secretion of α-amylase. Analysis of ER-enriched cell fractions revealed that AoVip36 and AoEmp47 were involved in the retention of heterologous proteins in the ER. However, the overexpression of each cargo receptor had a different effect on heterologous protein secretion: AoVip36 enhanced the secretion, whereas AoEmp47 promoted the intracellular retention. Taken together, our data suggest that AoVip36 and AoEmp47 hinder the secretion of heterologous proteins by promoting their retention in the ER but that AoVip36 also promotes the secretion of heterologous proteins. Moreover, we found that genetic deletion of these putative ER-Golgi cargo receptors significantly improves heterologous protein production. The present study is the first to propose that ER-Golgi transport is a bottleneck for heterologous protein production in filamentous fungi.
Expression of the Glucagon‐Like Peptide‐1 Receptor Gene in Rat Brain

Abstract: Evidence that glucagon‐like peptide‐1 (GLP‐1) (7–36) amide functions as a novel neuropeptide prompted us to study the gene expression of its receptor in rat brain. Northern blot analysis showed transcripts of similar size in RINm5F cells, hypothalamus, and brainstem. First‐strand cDNA was prepared by using RNA from hypothalamus, brainstem, and RINm5F cells and subsequently amplified by PCR. Southern blot analysis of the PCR products showed a major 1.4‐kb band in all these preparations. PCR products amplified from hypothalamus were cloned, and the nucleotide sequence of one strand was identical to that described in rat pancreatic islets. In situ hybridization studies showed specific labeling in both neurons and glia of the thalamus, hypothalamus, hippocampus, primary olfatory cortex, choroid plexus, and pituitary gland. In the hypothalamus, ventromedial nuclei cells were highly labeled. These findings indicate that GLP‐1 receptors are actually synthesized in rat brain. In addition, the colocalization of GLP‐1 receptors, glucokinase, and GLUT‐2 in the same areas supports the idea that these cells play an important role in glucose sensing in the brain.
Influence of visual field testing frequency on detection of glaucoma progression with trend analyses.

OBJECTIVE To explore whether increased frequency of visual field testing leads to earlier detection of glaucoma progression with trend analyses. METHODS The visual fields of 468 eyes (381 patients) from the Advanced Glaucoma Intervention Study with 10 or more reliable visual field tests and 3 or more years of follow-up were studied. Starting at year 1, every other visual field examination was deleted to create a low-frequency data set, and the original group was kept as the high-frequency data set. The proportion of progressing eyes and the time to progression were compared between the 2 data sets with global and pointwise linear regression criteria. RESULTS The median number of visual field examinations was 20 and 12 for the high- and low-frequency data sets, respectively. Based on primary mean deviation criteria, 204 eyes (43.6%) in the high-frequency data set and 160 eyes (34.2%) in the low-frequency data set progressed (P < .001), whereas 185 eyes (39.5%) in the high-frequency data set and 167 eyes (35.7%) in the low-frequency data set progressed according to pointwise linear regression (P = .02). The high-frequency data set was more likely to detect progression with mean deviation (hazard ratio [HR], 1.69 [95% confidence interval {CI}, 1.36-2.10]) or pointwise linear regression criteria (HR, 1.52 [95% CI, 1.21-1.90]). A similar number of improving eyes were detected with mean deviation criteria (HR, 0.95 [95% CI, 0.58-1.60]), but pointwise linear regression criteria were more likely to detect improvement in the high-frequency data set (HR, 2.27 [95% CI, 1.43-3.62]). The results did not significantly change after censoring data at 5 years. CONCLUSIONS Increasing the frequency of visual field testing leads to earlier detection of glaucoma progression, especially with global trend analyses. This finding has significant implications for the care of patients with glaucoma.
