1. EMERGENCE OF COLISTIN RESISTANCE OF MDR ACINETOBACTER SPP. IN HOSPITAL SUNGAI BULOH DURING COVID-19 PANDEMIC

Author: A. Amir, F.S. Abdul Aziz, N.H.A. Abdul Halim, N.A. Misnan, I.M. Idham, and N. Lai
Subjects: Infectious and parasitic diseases, RC109-216
Abstract: Intro: Acinetobacter calcoaceticus – A.baumannii complex is an opportunistic pathogen that has emerged as one of the multidrug resistant organism frequently associated with nosocomial infections especially causing ventilator- associated pneumonia (VAP). Colistin and Polymyxin B are currently being used as salvage therapy for treating MDR Acinetobacter spp. However, the emergence of resistance of colistin has been reported and treatment is further complicated by poor lung tissue penetration. Thus, we implied to explore on the prevalence of its resistance in our own facility, being the national COVID-19 referral hospital. Methods: This is a cross-sectional retrospective analysis of MDR Acinetobacter spp. done for isolates of 2019 and 2021. Only clinically significant isolates were sent to Institute of Medical Research (IMR) for colistin susceptibility testing by broth microdilution. The identification of the isolates was performed by Bruker® MALDI-ToF. CLSI breakpoints were used to determine susceptibility, applying the change of breakpoints interpretation in year 2020. Findings: In 2021, out of 203 isolates, 195 (96%) were Acinetobacter baumannii. Other spp. isolated were A. nosocomialis (6, 3%) and A. proteolyticus (2, 1%). Out of that, 107 (52.7%) were resistant with MIC of >4 ug/ml and 96 (47.3 %) were intermediate with MIC of 4 ug/ml and 52% were susceptible with MIC

Abstract: BACKGROUND AND OBJECTIVES: The coffee agroindustry in Indonesia plays a significant economic role as the third largest coffee producer worldwide. Despite the high economic contribution, the coffee agroindustry also raises environmental issues along its supply chain. Coffee solid waste constitutes biomass containing useful compounds promising as raw materials for added-value products through the implementation of industrial symbiosis. Eco-industrial parks create value through industrial symbiosis, emphasizing the principle of a closed-loop production system, simultaneously decreasing the use of raw materials and waste. This study aimed to analyze and develop a coffee-based eco-industrial park design via a systems engineering approach and optimization of industrial symbiosis in closed-loop coffee production.METHODS: This study employed a case study in the Ketakasi coffee-producing center in Jember, Indonesia. Data collection was conducted through field observation and a series of in-depth interviews. The development of eco-industrial park design followed a systems engineering methodology, as demonstrated through the utilization of Business Process Model and Notation. Subsequently, the optimization of industrial symbiosis within eco-industrial parks was realized using a mixed-integer linear programming mathematical model.FINDINGS: The eco-industrial park design presents the actors, internal business processes, material and data exchanges, various actors’ interdependence and critical roles in material exchanges, and value creation processes using valorization within the eco-industrial park. The role of the Ketakasi cooperative as a facilitator of material exchange and manager of the eco-industrial park is pivotal. The utilization of data integration enhances the transparency and efficiency of information exchange among eco-industrial park participants, promoting predictability and reliability in material exchange. The application of the mixed-integer linear programming optimization model has provided a structured approach to maximizing the value creation within the eco-industrial park through the valorization of 72.3 percent of coffee pulp and 68.5 percent of spent coffee grounds into cellulase enzymes and ultraviolet shields.CONCLUSION: This paper presents a structured framework for efficiently managing material exchange processes within an eco-industrial park, contributing to environmental sustainability and economic value creation. This study contributes to the knowledge gap in the literature by developing an inclusive eco-industrial park design that facilitates the optimization of the value creation process through valorization technology. This study also adds to sustainable agriculture management literature through a coffee-based eco-industrial park design.

Subjects: Medicine, Science
Abstract: Abstract The Arg-specific gingipains of Porphyromonas gingivalis RgpA and RgpB have 97% identical sequences in their catalytic domains yet their propeptides are only 76% identical. RgpA isolates as a proteinase–adhesin complex (HRgpA) which hinders direct kinetic comparison of RgpAcat as a monomer with monomeric RgpB. We tested modifications of rgpA identifying a variant that enabled us to isolate histidine-tagged monomeric RgpA (rRgpAH). Kinetic comparisons between rRgpAH and RgpB used benzoyl-l-Arg-4-nitroanilide with and without cysteine and glycylglycine acceptor molecules. With no glycylglycine, values of K m, V max, k cat and k cat/K m for each enzyme were similar, but with glycylglycine K m decreased, V max increased and k cat increased ~ twofold for RgpB but ~ sixfold for rRgpAH. The k cat/K m for rRgpAH was unchanged whereas that of RgpB more than halved. Recombinant RgpA propeptide inhibited rRgpAH and RgpB with K i 13 nM and 15 nM K i respectively slightly more effectively than RgpB propeptide which inhibited rRgpAH and RgpB with K i 22 nM and 29 nM respectively (p

Abstract: We report a measurement of the strong coupling constant, ${\ensuremath{\alpha}}_{s}({M}_{Z})$, extracted from inclusive jet production in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1800\mathrm{GeV}$. The QCD prediction for the evolution of ${\ensuremath{\alpha}}_{s}$ with jet transverse energy ${E}_{T}$ is tested over the range $40l{E}_{T}l450\mathrm{GeV}$ using ${E}_{T}$ for the renormalization scale. The data show good agreement with QCD in the region below 250 GeV. The value of ${\ensuremath{\alpha}}_{s}$ at the mass of the ${Z}^{0}$ boson averaged over the range $40l{E}_{T}l250\mathrm{GeV}$ is found to be ${\ensuremath{\alpha}}_{s}({M}_{Z})\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}0.1178\ifmmode\pm\else\textpm\fi{}0.0001(\mathrm{stat}{)}_{\ensuremath{-}0.0095}^{+0.0081}(\mathrm{expt}.\mathrm{syst})$. The associated theoretical uncertainties are mainly due to the choice of renormalization scale $({+6%}{\ensuremath{-}4%})$ and input parton distribution functions $(5%)$.

Abstract: Objective To characterize the phenotypes of Dent disease in Chinese children and their heterozygous mothers and to establish genetic diagnoses. Study design Using a modified protocol, we screened 1288 individuals with proteinuria. A diagnosis of Dent disease was established in 19 boys from 16 families by the presence of loss of function/deleterious mutations in CLCN5 or OCRL1 . We also analyzed 16 available patients' mothers and examined their pregnancy records. Results We detected 14 loss of function/deleterious mutations of CLCN5 in 15 boys and 2 mutations of OCRL1 in 4 boys. Of the patients, 16 of 19 had been wrongly diagnosed with other diseases and 11 of 19 had incorrect or unnecessary treatment. None of the patients, but 6 of 14 mothers, had nephrocalcinosis or nephrolithiasis at diagnosis. Of the patients, 8 of 14 with Dent disease 1 were large for gestational age (>90th percentile); 8 of 15 (53.3%) had rickets. We also present predicted structural changes for 4 mutant proteins. Conclusions Pediatric Dent disease often is misdiagnosed; genetic testing achieves a correct diagnosis. Nephrocalcinosis or nephrolithiasis may not be sensitive diagnostic criteria. We identified 10 novel mutations in CLCN5 and OCRL1 . The possibility that altered CLCN5 function could affect fetal growth and a possible link between a high rate of rickets and low calcium intake are discussed.

Abstract: Background Pseudoachalasia is a rare diagnosis manifested by clinical and physiologic symptoms of achalasia, with alternative etiology for outflow obstruction. While malignancy is a frequent cause of pseudoachalasia, prior surgical intervention especially surgery involving the esophagogastric junction, may result in a misdiagnosis of achalasia. Case presentation We present a case of a 70 year-old male with dysphagia and weight loss after undergoing a Billroth I and Nissen fundoplication several decades ago. His preoperative studies suggested achalasia and he was therefore referred for an endoscopic myotomy. However, careful interpretation of all the data and intra-operative findings revealed a classic mechanical and functional obstruction requiring takedown of his prior wrap. Conclusions Individualized interpretation of preoperative studies in the setting of prior foregut surgery is critical to appropriate diagnosis and intervention. This case highlights the significance of endoscopic findings and features of high-resolution manometry specific to pseudoachalasia, which contrasts with classical features of achalasia.

Abstract: Immunoglobulin A nephropathy (IgAN) is a worldwide disease characterized by the presence of galactose-deficient IgA1 deposits in the glomerular mesangium. A kidney biopsy for diagnosis is required. Here, we measured two miRNAs (let-7b and miR-148b), previously identified as regulators of the O-glycosylation process of IgA1, in serum samples from patients with IgAN and healthy blood donors (controls) recruited in an international multicenter study. Two predictive models, based on these miRNAs, were developed and the diagnostic accuracy of the combined biomarkers was assessed by the area under the receiver operating characteristic (ROC) curve (AUC) carried out in three steps. In a training study, the combined miRNAs were able to discriminate between 100 patients with IgAN and 119 controls (AUC, 0.82). A validation study confirmed the model in an independent cohort of 145 patients with IgAN and 64 controls (AUC, 0.78). Finally, in a test study, the combined biomarkers were able to discriminate patients with IgAN from 105 patients affected by other forms of primary glomerulonephritis, supporting the specificity (AUC, 0.76). Using the same study design, we also performed two subgroup analyses (one for Caucasians and one for East Asians) and found that race-specific models were the best fit to distinguish IgAN patients from controls. Thus, serum levels of the combined miRNA biomarker, let-7b and miR-148b, appears to be a novel, reliable, and noninvasive test to predict the probability of having IgAN.

Abstract: Background Previously, a large proportion of the genetic components predisposing individuals to IgA nephropathy (IgAN) have been unidentified. Familial IgAN is enriched with genetic variations predisposing individuals to the disease. Whole exome sequencing is an effective way to explore disease-causing genes and gene variants. Methods We performed exome sequencing on the probands from each of ten IgAN families, and on one of the unaffected member from 7 of the families. Sanger sequencing, bioinformatics and co-segregation analysis were performed for all available family members to detect deleterious genetic variation. The relatedness of the families was tested by haplotype analyses. Results Six deleterious variants in 4 genes were observed to be associated with IgA nephropathy by co-segregating with the disease phenotypes in study families. MYCT1 p.Asp22Glufs*34 was associated with IgAN by co-segregating with its phenotypes in families 2, 7, and 9; DEFA4 p.Ala8Pro, p.Ala8Val, c.172 + 1G>T co-segregated in families 1, 2, and 3; ZNF543 p.Pro226Ala co-segregated in families 3, 5, and 6 and CARD8 p.Val98Lysfs*26 co-segregated in families 7 and 8. Among these genes, MYCT1, CARD8 and ZNF543 are novel. Our haplotype analyses showed that families in which the same variation(s) were co-segregating with IgAN were unrelated, except for DEFA4. Of the families carrying DEFA4, families 2 and 3 were possibly related, but not family 1, indicating that common genes/variations in these families were not due to the same founder. Interfamilial sharing of different co-segregating genes was also observed, demonstrating the polygenic nature of this disease. Conclusions We discovered 6 deleterious variants in 4 genes associated with familial IgAN. These genes are good candidate genes that appear to be causally related to IgAN and warrant further study.

Abstract: An analytical methodology is developed to study the pollutant dispersion in a turbulent wind flow over a two-dimensional hill with a small slope. As in a typical boundary layer problem, the flow domain is divided into an inner and an outer region: the inviscid outer region is further subdivided into an upper and a middle layer while the viscous inner region is subdivided into a shear stress and an inner surface layer. Based on the Reynolds-averaged Navier-Stokes equations and the continuity equations, closed form analytical solutions of the stream functions and velocities are readily obtained for all regions in the domain. The velocity information is then imported into the diffusion equation, and the pollutant concentration distribution is readily solved. For reasons of turbulent shear, a variational method with adjustments to the streamline coordinate system is used to obtain an accurate solution of the pollutant concentration. Results show that when the source is located in the upper layer, the concentrations decrease with distance along the upwind side of the hill and tend to reach a constant value rapidly near the hilltop. Similar results are observed when the source is located in the middle layer. However, due to the reduction of wind speed in the middle layer, the concentrations become saturated at a later upslope position as compared to the source in the upper layer. This methodology is shown to be able to provide a quick and accurate estimate of local pollutant patterns and can be applied to any flow field provided that the streamlines can be specified through the velocities.

Abstract: Background Information on the clinical features of the severe acute respiratory syndrome (SARS) will be of value to physicians caring for patients suspected of having this disorder. Methods We abstracted data on the clinical presentation and course of disease in 10 epidemiologically linked Chinese patients (5 men and 5 women 38 to 72 years old) in whom SARS was diagnosed between February 22, 2003, and March 22, 2003, at our hospitals in Hong Kong, China. Results Exposure between the source patient and subsequent patients ranged from minimal to that between patient and health care provider. The incubation period ranged from 2 to 11 days. All patients presented with fever (temperature, >38°C for over 24 hours), and most presented with rigor, dry cough, dyspnea, malaise, headache, and hypoxemia. Physical examination of the chest revealed crackles and percussion dullness. Lymphopenia was observed in nine patients, and most patients had mildly elevated aminotransferase levels but normal serum creatinine levels...

Abstract: We present the results of a search for neutral Higgs bosons produced in association with b quarks in pp-->bb(phi)-->bbb final states with 91+/-7 pb(-1) of pp collisions at sqrt[s] = 1.8 TeV recorded by the Collider Detector at Fermilab. We find no evidence of such a signal and the data are interpreted in the context of the neutral Higgs sector of the minimal supersymmetric extension of the standard model. With basic parameter choices for the supersymmetric scale and the stop-quark mixing, we derive 95% C.L. lower mass limits for neutral Higgs bosons for tan(beta) values in excess of 35.

Abstract: We have measured the ratio of prompt production rates of the charmonium states {chi}{sub c1} and {chi}{sub c2} in 110 pb{sup -1} of p{ovr p} collisions at sqrt[s] = 1.8 TeV. The photon from their decay into J/{psi}{gamma} is reconstructed through conversion into e{sup +}e{sup -} pairs. The energy resolution this technique provides makes the resolution of the two states possible. We find the ratio of production cross sections {sigma}{sub {chi}{sub c2}}/{sigma}{sub {chi}{sub c1}} = 0.96{+-}0.27(stat){+-}0.11(syst) for events with p{sub {tau}}(J/{psi})>4.0 GeV/c, |{eta}(J/{psi})| 1.0 GeV/c.

Abstract: An angular analysis of B{sup 0}{yields}J/{psi}K*{sup 0} and B{sup 0}{sub s}{yields}J/{psi}{phi} has been used to determine the decay amplitudes with parity-even longitudinal (A{sub 0}) and transverse (A{sub {parallel}}) polarization and parity-odd transverse (A{sub {perpendicular}}) polarization. The measurements are based on 190 B{sup 0} and 40 B{sup 0}{sub s} candidates obtained from 89 pb{sup -1} of p{ovr p} collisions at the Fermilab Tevatron. The longitudinal decay amplitude dominates with |A{sub 0}|{sup 2} = 0.59{+-}0.06{+-}0.01 for B{sup 0} and |A{sub 0}|{sup 2} = 0.61{+-}0.14{+-}0.02 for B{sup 0}{sub s} decays. The parity-odd amplitude is found to be small with |A{sub {perpendicular}}|{sup 2} = 0.13{sub -0.09}{sup +0.12}{+-}0.06 for B{sup 0} and |A{sub {perpendicular}}|{sup 2} = 0.23{+-}0.19{+-}0.04 for B{sup 0}{sub s} decays.

Abstract: This Letter describes a direct measurement of the W boson total decay width, {Gamma}{sub W}, using the Collider Detector at Fermilab. The measurement uses an integrated luminosity of 90 pb{sup -1}, collected during the 1994-1995 run of the Fermilab Tevatron p{anti p} collider. The width is determined by normalizing predicted signal and background distributions to 49 844 W {yields}e{nu} candidates and 21 806 W{yields}{mu}{nu} candidates in the transverse-mass region M{sub T}

Abstract: We have measured the polarization of J/psi and psi(2S) mesons produced in pp collisions at sqrt[s] = 1.8 TeV, using data collected at the Collider Detector at Fermilab during 1992-1995. The polarization of promptly produced J/psi [psi(2S)] mesons is isolated from those produced in B-hadron decay, and measured over the kinematic range 4 [5.5]

Abstract: We use 106 pb{sup -1} of data collected with the Collider Detector at Fermilab to search for narrow-width, vector particles decaying to a top and an antitop quark. Model independent upper limits on the cross section for narrow, vector resonances decaying to t{ovr t} are presented. At the 95% confidence level, we exclude the existence of a leptophobic Z' boson in a model of top-color-assisted technicolor with mass M{sub Z'}

Abstract: Events collected by the Collider Detector at Fermilab (CDF) with an energetic jet plus large missing transverse energy can be used to search for physics beyond the standard model. We see no deviations from the expected backgrounds and set upper limits on the production of new processes. We consider in addition the production of light gravitinos and set a limit at 95% confidence level on the breaking scale root F greater than or equal to 217 GeV, which excludes gravitino masses smaller than 1.1 X 10(-5) eV/c(2).

Abstract: We have searched for direct pair production of scalar top and scalar bottom quarks in 88 pb-1 of pp collisions at sqrt[s]=1.8 TeV with the CDF detector. We looked for events with a pair of heavy flavor jets and missing energy, consistent with scalar top (bottom) quark decays to a charm (bottom) quark and a neutralino. The numbers of events that pass our selections show no significant deviation from standard model expectations. We compare our results to the next-to-leading order scalar quark production cross sections to exclude regions in scalar quark-neutralino mass parameter space.

Abstract: We have searched for direct production of scalar top quarks at the Collider Detector at Fermilab in 88 pb{sup -1} of pp collisions at {radical}(s)=1.8 TeV . We assume the scalar top quark decays into either a bottom quark and a chargino or a bottom quark, a lepton, and a scalar neutrino. The event signature for both decay scenarios is a lepton, missing transverse energy, and at least two b -quark jets. For a chargino mass of 90 GeV/c{sup 2} and scalar neutrino masses of at least 40 GeV/c{sup 2} , we find no evidence for scalar top production and present upper limits on the production cross section in both decay scenarios.

Abstract: We have reconstructed the radiative decays chi(b)(1P)-->Upsilon(1S)gamma and chi(b)(2P)-->Upsilon(1S)gamma in pp collisions at sqrt[s] = 1.8 TeV, and measured the fraction of Upsilon(1S) mesons that originate from these decays. For Upsilon(1S) mesons with p(Upsilon)(T)>8.0 GeV/c, the fractions that come from chi(b)(1P) and chi(b)(2P) decays are [27.1+/-6.9(stat)+/-4. 4(syst)]% and [10.5+/-4.4(stat)+/-1.4(syst)]%, respectively. We have derived the fraction of directly produced Upsilon(1S) mesons to be [50.9+/-8.2(stat)+/-9.0(syst)]%.

Abstract: We have studied the production of B hadrons in 1.8-TeV pp(bar sign) collisions. We present measurements of the fragmentation fractions, f{sub u} , f{sub d} , f{sub s} , and f{sub baryon} , of produced b quarks that yield B{sup +} , B{sup 0} , B{sup 0}{sub s} , and {lambda}{sup 0}{sub b} hadrons. Reconstruction of five electron-charm final states yields f{sub s}/( f{sub u}+f{sub d})=0.213{+-}0.068 and f{sub baryon}/( f{sub u}+f{sub d})=0.118{+-}0.042 , assuming f{sub u}=f{sub d} . If all B hadrons produced in pp(bar sign) collisions cascade to one of these four hadrons, we determine f{sub u}=f{sub d}=0.375{+-}0.023 , f{sub s}=0.160{+-}0.044 , and f{sub baryon}=0.090{+-}0.029 . If we do not assume f{sub u}=f{sub d} , we find f{sub d}/f{sub u}=0.84{+-}0.16 . (c) 2000 The American Physical Society.

Abstract: We search for color singlet technirho and technipion production in $p\overline{p}$ collisions at $\sqrt{s}\phantom{\rule{0ex}{0ex}}=\phantom{\rule{0ex}{0ex}}1.8\phantom{\rule{0ex}{0ex}}\mathrm{TeV}$ recorded with the Collider Detector at Fermilab. These exotic technimesons are present in a model of walking technicolor. The signatures studied are lepton plus two jets plus ${E}_{T}$ and multijet final states. No excess of events is seen in either final state. We set an upper limit on the technirho production cross section and exclude a region in the technipion mass versus technirho mass plane.

Abstract: We compared the clinicopathologic features of 22 patients with hepatitis B virus-related membranous nephropathy, all with detectable glomerular hepatitis B e antigen, and of 26 patients with lupus nephritis class V. Both groups of patients similarly presented with heavy proteinuria or nephrotic syndrome; however, the patients with hepatitis B virus-related membranous nephropathy, who were predominantly male, did not have the extrarenal manifestations and autoantibodies seen in systemic lupus erythematosus. The glomerular lesions in both clinical entities were similar and at times indistinguishable, demonstrating polyclonal immunoglobulins and polytypic complements in similar subepithelial ultrastructural distribution. No morphologic feature, single or combined, carrying a high positive predictive value for the diagnosis of either nephritis was identified. Lesions such as hematoxyphil bodies and fingerprint dense deposits, distinctive of systemic lupus erythematosus, were rarely found. At the time of biopsy, when systemic lupus erythematosus is not clinically suspected, the diagnosis between hepatitis B virus-related membranous nephropathy and lupus nephritis may be difficult or impossible to differentiate, especially in geographic areas where both lupus nephritis and hepatitis B surface antigen carriers are common. This study focused on the use of specific monoclonal antisera to detect glomerular hepatitis B virus antigens, which contribute to the diagnosis of hepatitis B virus-related nephritis.

Abstract: We present the results of a search for pair production of a fourth-generation charge -1 / 3 quark (b(')) in sqrt[s] = 1.8 TeV pp collisions using 88 pb(-1) of data obtained with the Collider Detector at Fermilab. We assume that both quarks decay via the flavor-changing neutral current process b(')-->bZ(0) and that the b(') mass is greater than m(Z)+m(b). We studied the decay mode b(')b(');-->Z(0)Z(0)bb where one Z0 decays into e(+)e(-) or m(+)m(-) and the other decays hadronically, giving a signature of two leptons plus jets. An upper limit on the sigma(pp-->b(')b(');)x[B(b(')-->bZ(0))](2) is established as a function of the b(') mass. We exclude at 95% confidence level a b(') quark with mass between 100 and 199 GeV/c(2) for B(b(')-->bZ(0)) = 100%.

Abstract: We update the measurement of the t (t) over bar production cross section using the CDF detector at the Fermilab Tevatron. This measurement uses t (t) over bar decays to the final states e + nu + jets and mu + nu + jets. We search for b quarks from t decays via secondary-vertex identification or the identification of semileptonic decays of the b and cascade c quarks. The background to the t (t) over bar production is determined primarily through a Monte Carlo simulation. However, we calibrate the simulation and evaluate its uncertainty using several independent data samples. For a top quark mass of 175 GeV/c(2), we measure sigma (t (t) over bar)-=5.1 +/- 1.5 pb and sigma (t (t) over bar)=9.2 +/- 4.3 pb using the secondary vertex and the lepton tagging algorithms, respectively. Finally, we combine these results with those from other t (t) over bar decay channels and obtain sigma (t (t) over bar)-= 6.5 (+1.7)(-1.4)pb.

Abstract: Soluble interleukin-2 receptor (sIL-2R) is a marker of T-lymphocyte activation. We have undertaken a study to examine the serum sIL-2R levels in patients with pulmonary tuberculosis (TB) and the changes following anti-TB chemotherapy. Forty four patients with pulmonary TB or tuberculous pleural effusion were recruited. Serum was collected from the patients before and at 1, 2, 4 and 6 months after initiation of anti-TB chemotherapy. Serum sIL-2R level was measured by an enzyme immunoassay. The mean sIL-2R level before treatment was 1,452 +/- 103 (SEM) U.ml-1, which was significantly higher than that of healthy control subjects (374 +/- 30 U.ml-1). There was no significant change in the sIL-2R level at 1 month, but there was a gradual reduction from the second month onwards. At the sixth month the mean sIL-2R level was 1080 +/- 81 U.ml-1, which was significantly lower than that before treatment. However, despite clinical improvement, the sIL-2R levels at the sixth month were still significantly higher than those of control subjects. We conclude that sIL-2R levels were elevated in patients with pulmonary TB and there was a gradual reduction following anti-TB chemotherapy. However, the sIL-2R levels were still higher than control subjects at completion of treatment, suggesting a delayed resolution of the inflammation in patients with pulmonary TB.

Subjects: teacher-researcher role conflict, occupational well-being, innovative teaching, job demands-resources model, Education
Abstract: Innovation is the main source to remain competitive in today’s environment. As well as other employees, the lecturer is also required to do innovative teaching. But, encouraging lecturers’ willingness to do innovative teaching is challenging due to the dual roles as teachers and researchers. This study explores the predictor of innovative teaching by applying the job-demands resources model as a theoretical anchor. This research used the online questionnaire to collect the data from 233 samples taken randomly from nineteen universities in Indonesia. This study uses structural equation modeling (SEM) to examine the research model. The result indicated that teacher-researcher role conflict negatively predicted the innovative teaching of the lecturer. Besides, occupational well-being plays a mediating variable to explain the influence of teacher-researcher role conflict on innovative teaching. This study provides critical insight into the related stakeholders, such as the universities and related ministry, regarding the negative predictor of innovative teaching. They should discover approaches to reduce the negative effect of teacher-researcher conflict on the innovation behavior of lecturer teaching activity. The universities and related ministries have to ease the issue regarding job role conflict.

Abstract: Chronic hepatitis B (CHB) is a major global health issue. The role of rare genetic variants in CHB has not been elucidated. We aimed to identify rare allelic variants predisposing to CHB. We performed exome sequencing in 50 CHB patients who had no identifiable risk factors for CHB and 40 controls who were healthy and hepatitis B surface antibody-positive, but had never received hepatitis B vaccination. We selected six rare variant alleles and followed up their association with disease status by Sanger sequencing in a case-control study comprising 1,728 CHB patients and 1,636 healthy controls. The latter had either not been immunized with hepatitis B vaccine or had uncertain vaccination status. Our results showed that transmembrane protein 2 p.Ser1254Asn, interferon alpha 2 p.Ala120Thr, its regulator NLR family member X1 p.Arg707Cys, and complement component 2 p.Glu318Asp were associated with CHB, with P values of

Abstract: SUMMARY IgA nephropathy (IgAN), characterized by glomerular deposition of IgA and frequently elevated plasma IgA levels, has increased T helper cell activity. In vitro measurement of cytokines in supernatant of cultured peripheral lymphocytes revealed conflicting findings. We examined the profile of cytokine mRNA expressed in purified CD4+ cells in patients with IgAN in order to study their pattern of Th1 (releases IL-2 and interferon-gamma (IFN-γ)) and Th2 (releases IL-4 and IL-5) T cell response. We assessed the circulating CD4+ T cells in patients and normal controls by the expression of messenger RNA (mRNA) for IL-2, IL-4, IL-5 and IFN-γ. The cytokine mRNAs were analysed with reverse transcription-polymerase chain reaction and were measured semiquantitatively by using a housekeeping gene, β-actin. Compared with the control subjects, CD4+ T lymphocytes from patients with IgAN expressed a higher level of IL-2 mRNA (P=0·007), IFN-γ mRNA (P = 0·04), IL-4 mRNA (P = 0·048), and IL-5 mRNA (P=0·016). Within these patients with IgAN, a good correlation was demonstrated between the gene expression of cytokines in Th1 or Th2 cells. The IL-2 mRNA levels in Th1 cells from these patients with IgAN also correlated significantly with the IL-4 or IL-5 mRNA levels in their Th2 cells. Our study revealed IgAN is associated with activation in circulating lymphocytes of the IL-2, IFN-γ, IL-4 and IL-5 gene cluster, a pattern compatible with activation of both the Th1- and Th2-like T lymphocyte population. The increased transcription of these cytokine genes may be contributory to the immunopathologic findings in IgAN.

Abstract: Chronic NG-nitro-l-arginine methyl ester (L-NAME) administration induces cardiac hypertrophy in rodent models. Our aims is to determine the role of c-kit expression in L-NAME induced cardiac hypertrophy. 12-20 week old C57BL/6J mice (5 per group) were administered L-NAME (0.325mg/ml) in the drinking water. Hearts were excised at 1-day, 2-days, 5-days, 2-weeks or 6-weeks; or controls which received no L-NAME. Ventricular cross-sectional wall thickness and individual cardiac myocytes cross-sectional area and cardiomyocyte/nuclear ratio to determine cardiac hypertrophy. Immuno-histochemical staining for c-kit, sca-1 and BCRP undertaken. Six weeks L-NAME administration induced significant cardiac hypertrophy compared to control hearts, evidenced by an increase in the thickness of the cross-sectional free ventricular wall (p0.05) and an increase in mean individual cross-sectional area of cardiac myocytes in the LV wall (p0.007). We observed c-kit(+) cells (predominately non-mast cell sub-types) in both healthy mice and in the L-NAME treated mice. C-kit staining in the left ventricular cross sections following L-NAME remained stable at 1 and 2 days compared to controls (p=NS). After 5 days of L-NAME we observed c-kit expression to decrease below control levels (p0.05) and these lower levels were sustained at 2 and 6 weeks. C-kit expression does not decrease during two days of L-NAME administration, suggesting, firstly, that the later decrease in c-kit is not due to NOS inhibition directly and, secondly, there is the possibility for c-kit(+) cell differentiation into other cell types, possibly inducing myocardial cellular hyperplasia, without significant replacement of the original pool of c-kit(+) cells.

Subjects: Immunology, Immunology and Allergy
Abstract: SUMMARY Leucocyte-endothelial adhesion molecules have been implicated in the pathogenesis of inflammatory diseases. To evaluate their role as markers of disease activity in tuberculosis, we have used an antigen capture ELISA to measure the serum concentrations of circulating intercellular adhesion molecule-1 (cICAM-1), E-selectin (cE-selectin) and vascular cell adhesion molecule-1 (cVCAM-1) in 34 patients with active tuberculosis (27 with pulmonary disease and seven with lymph node disease) before the commencement of standard chemotherapy, 15 subjects who had previously completed treatment for pulmonary tuberculosis, and 27 healthy volunteers. Circulating ICAM-1 and E-selectin levels were significantly elevated in patients with active tuberculosis when compared to those with treated disease (P⩽0.01), and healthy controls (P< 0.02). Circulating VCAM-1 was raised in patients with active or old pulmonary tuberculosis (P

Abstract: The T cell receptor alpha constant gene (TRAC) encodes the constant region of the α chain for the T cell receptor, and the association of its gene variants with IgA nephropathy remains controversial. The authors resequenced the gene in 100 patients with IgA nephropathy and 100 controls, tested its linkage disequilibrium pattern, constructed haplotypes, and performed association and functional studies. First, the association between TRAC variants and IgA nephropathy was tested in 704 patients and 704 controls. Next, these 704 patients were divided into two independent datasets - 310 with family member(s) and 394 single patients - to test the association separately. Results showed that the gene is located in a recombination hot spot, with nine linkage disequilibrium blocks within a 6.9-kb region. There is a hypervariable region with six single-nucleotide polymorphisms (SNPs) in an 85-bp stretch in intron 1. We identified multiple SNPs and two haplotypes that associate with IgA nephropathy (P = 0.0000013-0.0096 by logistic regression for SNPs; P = 0.0003 and P = 0.0398 for haplotype associations). The family-based study replicated both haplotype findings, and the 394 single-patient case-control study replicated the association with haplotype 1 (P = 0.0033). The overtransmitted/observed haplotypes demonstrated reduced transcription activity compared with the undertransmitted/observed haplotypes. In conclusion, this study suggests an association between TRAC variants and susceptibility to IgA nephropathy. Copyright © 2009 by the American Society of Nephrology., link_to_OA_fulltext

Abstract: Introduction. To keep in pace and remain competitive in today's environment, the lecturer must do innovation in educational process. However, encouraging lecturers' willingness to do innovative teaching is challenging in higher education due to the dual roles as teachers and researchers, which makes the excessive workload and leads to the teacher-researcher role conflict (TRC). Therefore, it is crucial to analyse the impact of TRC on the innovative teaching of lecturers. The present study utilises the job demands-resources (JDR) model due to its high popularity but rarely used in higher education.Aim. This study is aimed to explore the predictor of innovative teaching by utilising the JDR model as a theoretical anchor.Methodology and research methods. This study uses structural equation modelling (SEM) to examine the research model on a random sample of 233 respondents.Results. The results indicated that teacher-researcher role conflict negatively predicted the innovative teaching of the lecturer. Besides, the occupational well-being is a mediating variable to explain the influence of teacher-researcher role conflict on innovative teaching.Scientific novelty. This study reveals innovative teaching predictors in higher education by using the JDR model as a theoretical anchor. The authors found out that teacher-researcher role conflict (TRC) was significantly related to innovative teaching. The high-level expression of TRC will reduce the lecturer's innovative behaviour on teaching activity, and vice versa.Practical significance. The current study provides critical insight into the related stakeholders, such as the universities and related ministries, regarding the negative predictor of innovative teaching. They should discover approaches to reduce the negative effect of TRC on the innovation behaviour of lecturer teaching activity and to address the problem of job role conflict.

Abstract: This study investigated the use of peritoneal dialysis fluid (dialyzate) as a MR contrast agent to visualize the liver structure and peritoneal adhesion in rats at 7 T. Intraperitoneal injection of dialyzate (0.1 ml/g) yielded excellent and consistent intraperitoneal enhancement that delineated the liver lobular structure in all rats studied (N 8). It also allowed the MR detection of peritoneal adhesions that were surgically induced. MR measurements of adhesion surface areas correlated well with the postmortem estimations (R 0.99; N 6). Dialyzate persisted in the intraperitoneal cavity for up to 2 days. T1 and T2 values of undiluted dialyzate were found to be 3017.5 35.3 ms and 108.4 2.0 ms, respectively. These findings demonstrated dialyzate-enhanced MRI as a potentially valuable technique to localize certain activities within liver (such as local tumor metastasis), and to monitor therapeutic interventions (e.g., against peritoneal adhesion) in preclinical research using small animal models.

Abstract: Background. MEGSIN is a gene predominantly expressed in the renal mesangium, and is upregulated in IgA nephropathy (IgAN). Our previous study has shown that the 2093C and 2180T alleles at the 3 0 untranslated region (3 0 UTR) of the gene are associated with susceptibility to IgAN, but the relationships of these genetic variants with the clinical manifestations and renal histological lesions of IgAN have not been examined previously. Methods. 302 IgAN patients followed up for 52.8±22.5 months were investigated. Haplotypes at the 3 0 UTR were constructed using the 2093C/T and 2180C/T alleles. The genotype–phenotype relationship was studied by correlations of haplotypes and the clinical data and renal histopathological changes. Results. The 2093C–2180T haplotype was present more often in patients with disease that progressed more rapidly (w2(C-T/others) ¼ 8.429, P ¼ 0.004), and was also correlated with hypertension (w2(C-T/others) ¼ 6.459, P ¼ 0.012), severe proteinuria (� 2 g/d) (w2(C-T/others) ¼ 6.332, P ¼ 0.013), and Lee’s class IV and V histological changes (w2(C-T/others) ¼ 9.640, P ¼ 0.008). Conclusion. In this Chinese population, the 2093C–2180T haplotype at the 3 0 UTR of MEGSIN gene is associated with more severe forms of IgAN, and more rapid disease progression. This provides further evidence for the involvement of genetic variations of MEGSIN in the pathogenesis of IgAN.
