    Zinc (Zn) is a co-factor for a vast number of enzymes, and functions as a regulator for immune mechanism and protein synthesis. However, excessive Zn release induced in pathological situations such as stroke or transient global ischemia is toxic. Previously, we demonstrated that the interaction of Zn and copper (Cu) is involved in the pathogenesis of Alzheimer's disease and vascular dementia. Furthermore, oxidative stress has been shown to play a significant role in the pathogenesis of various metal ions induced neuronal death. Thioredoxin-Albumin fusion (HSA-Trx) is a derivative of thioredoxin (Trx), an antioxidative protein, with improved plasma retention and stability of Trx. In this study, we examined the effect of HSA-Trx on Cu2+/Zn2+-induced neurotoxicity. Firstly, HSA-Trx was found to clearly suppress Cu2+/Zn2+-induced neuronal cell death in mouse hypothalamic neuronal cells (GT1-7 cells). Moreover, HSA-Trx markedly suppressed Cu2+/Zn2+-induced ROS production and the expression of oxidative stress related genes, such as heme oxygenase-1. In contrast, HSA-Trx did not affect the intracellular levels of both Cu2+ and Zn2+ after Cu2+/Zn2+ treatment. Finally, HSA-Trx was found to significantly suppress endoplasmic reticulum (ER) stress response induced by Cu2+/Zn2+ treatment in a dose dependent manner. These results suggest that HSA-Trx counteracted Cu2+/Zn2+-induced neurotoxicity by suppressing the production of ROS via interfering the related gene expressions, in addition to the highly possible radical scavenging activity of the fusion protein. Based on these findings, HSA-Trx has great potential as a promising therapeutic agent for the treatment of refractory neurological diseases.

    Oesophageal strictures often occur following esophagectomy which is performed for cases of oesophageal cancer. These patients require repeated dilation procedures. The aim of this study is to investigate the effects of dietary regimens, which are changed because of stenosis, caused by Helicobacter pylori (H. pylori). In this retrospective study, 28 patients who had operation for oesophageal cancer and underwent dilation due to development of stricture were studied. 30 female and 30 male patients who were admitted to the Gastroenterology Clinic with complaints of dyspepsia and did not receive treatment for the eradication of H. pylori were randomly selected and included in this study as a control group. Patients' histopathological records on the hemogram, biochemistry, and endoscopic biopsy were analysed. There were 26 H. pylori (+) cases (92.8 %) in the stenosis group consisting of 28 patients, and 37 H. pylori (+) cases (61.6%) in the control group consisting of 60 patients. These results were found to be statistically significant (P=0.003). The albumin level in the stenosis group was reported to be statistically low (P=0.002). The incidence of H. pylori was found to be significantly higher in patients with stenosis. We ascribed this outcome due to changes in dietary regimens. Our findings showed that the dietary regimens of all patients who underwent esophagectomy should be regulated during the postoperative period considering H. pylori. The relationship between H. pylori and stenosis was significant, there is a need for further research with a larger sample size to enrich the findings.

    Adamantyl-based compounds are commercially important in the treatments for neurological conditions and type-2 diabetes, aside from their anti-viral abilities. Their values in drug design are chronicled as multi-dimensional. In the present study, a series of 2-(adamantan-1-yl)-2-oxoethyl benzoates, 2(a-q), and 2-(adamantan-1-yl)-2-oxoethyl 2-pyridinecarboxylate, 2r, were synthesized by reacting 1-adamantyl bromomethyl ketone with various carboxylic acids using potassium carbonate in dimethylformamide medium at room temperature. Three-dimensional structures studied using X-ray diffraction suggest that the adamantyl moiety can serve as an efficient building block to synthesize 2-oxopropyl benzoate derivatives with synclinal conformation with a looser-packed crystal packing system. Compounds 2a, 2b, 2f, 2g, 2i, 2j, 2m, 2n, 2o, 2q and 2r exhibit strong antioxidant activities in the hydrogen peroxide radical scavenging test. Furthermore, three compounds, 2p, 2q and 2r, show good anti-inflammatory activities in the evaluation of albumin denaturation.

    INTRODUCTION: Long-acting recombinant factor IX (FIX) products may simplify the surgical treatment of haemophilia B patients. The impact of rIX-FP, a recombinant FIX fused to recombinant albumin, on FIX consumption and surgical management was assessed in patients with haemophilia B.

    MATERIALS AND METHODS: Male patients, ≤65 years old with severe haemophilia B (FIX activity ≤2%) requiring non-emergency surgery were enrolled in the surgical substudy of PROLONG-9FP. Dosing was based on World Federation of Hemophilia guidelines and patients' pharmacokinetics. Haemostatic efficacy was assessed on a 4-point scale. rIX-FP consumption and safety were monitored throughout the perioperative period.

    RESULTS: This updated dataset reports on thirty (8 minor and 22 major) surgeries conducted in 21 patients. A single preoperative bolus was used in 96.7% (n = 29) of surgeries. After minor surgery, patients received a median (range) of 0 (0-3) infusions with a median (range) consumption of 0 (0-178.89) IU/kg in the 14-day postoperative period. In patients who underwent major surgery (including 15 patients undergoing joint replacement surgery), the median (range) number of infusions in the 14-day postoperative period was 5 (0-11) and median consumption was 221.7 (0-444.07) IU/kg. Haemostatic efficacy was rated as excellent or good in 87.5% (7/8) of minor surgeries and 95.5% (21/22) of major surgeries.

    CONCLUSION: Surgical procedures can be performed using a single preoperative bolus of rIX-FP in nearly all patients. During postoperative care, use of rIX-FP necessitated infrequent infusions and low FIX consumption. Overall, data suggest rIX-FP simplifies perioperative care in patients with haemophilia B.

    The subchronic toxicity effect of the leaf extract of Carica papaya Linn. in Sprague Dawley (SD) rats was investigated in this study. The extract was prepared by dissolving the freeze dried extract of the leaves in distilled water and was administered orally to SD rats (consisted of 10 rats/sex/group) at 0 (control), 0.01, 0.14, and 2 g/kg body weight (BW) for 13 weeks. General observation, mortality, and food and water intake were monitored throughout the experimental period. Hematological and biochemical parameters, relative organ weights, and histopathological changes were evaluated. The study showed that leaf extract when administered for 13 weeks did not cause any mortality and abnormalities of behavior or changes in body weight as well as food and water intake. There were no significant differences observed in hematology parameters between treatment and control groups; however significant differences were seen in biochemistry values, for example, LDH, creatinine, total protein, and albumin. However, these changes were not associated with histopathological changes. In conclusion, the results suggested that daily oral administration of rats with C. papaya leaf extract for 13 weeks at a dose up to fourteen times the levels employed in traditional medicine practice did not cause any significant toxic effect.

    The quality of antivenom is governed by its safety and efficacy profiles. These quality characteristics are much influenced by the purity of antivenom content. Rigorous assessment and meticulous monitoring of antivenom purity at the preclinical setting is hence crucial. This study aimed to explore an integrative proteomic method to assess the physicochemical purity of four commercially available antivenoms in the region. The antivenoms were subjected to Superdex 200 HR 10/30 size-exclusion fast-protein liquid chromatography (SE-FPLC). The proteins in each fraction were trypsin-digested and analyzed by nano-ESI-liquid chromatography-tandem mass spectrometry (LC-MS/MS). SE-FPLC resolved the antivenom proteins into three major protein components of very high (>200 kDa), high (100-120 kDa) and medium (<60 kDa) molecular weights. The major components (80-95% of total proteins) in the antivenoms were proteins of 100-120 kDa consisting of mainly the light and partially digested heavy immunoglobulin chains, consistent with F(ab')2 as the active principle of the antivenoms. However, LC-MS/MS also detected substantial quantity of large proteins (e.g. alpha-2-macroglobulins), immunoglobulin aggregates and impurities e.g. albumins in some products. The method is practical and able to unveil the quantitative and qualitative aspects of antivenom protein compositions. It is therefore a potentially useful preclinical assessment tool of antivenom purity.

    Introduction: Delayed diagnosis of type 2 diabetes mellitus (T2D) increases the risk of presenting late with microvas- cular complications due to untreated long-standing hyperglycaemia. This study aimed to determine the prevalence of microvascular complications in newly diagnosed T2D patients in primary healthcare clinics.
    Methods: This was a cross-sectional study carried out in three government primary healthcare clinics in the state of Selangor, Malaysia. Malaysian aged 18 years and above with newly diagnosed T2D (<6 months of diagnosis) were invited to participate in the study. Data collected included the sociodemographic characteristic and the clinical profile (weight, height, waist circumference, blood pressure, lipid, glycaemic, urine albumin, microalbuminuria and renal profile). The assessment of nephropathy, peripheral neuropathy and retinopathy were performed using standard protocol. Multivariate logistic regression analysis was used to identify the significant factors that contribute to the presence of microvascular complications.
    Results: A total of 162 newly diagnosed patients were recruited. The majority was women (64%). The mean age was 51 (SD 11) years. About one-third of the patients (27.7%) had developed at least one microvascular complication. Nephropathy was the commonest microvascular complication (19.2%), followed by peripheral neuropathy (8.6%) and retinopathy (6.5%). Poor glycaemic control was found to be a significant factor contributing to the presence of microvascular complications (OR 5.8, 95%CI:1.466, 23.288).
    Conclusion: There is a high prevalence of microvascular complications among the newly diagnosed T2D. There is a need to develop appropriate strategies to increase the awareness and early detection of T2D.

    Introduction : A retrospective cohort study was conducted among ESRD who received dialysis treatment (Haemodialysis and CAPD) in all government hospitals in the State of Pahang from 1st January 2000 to 31st December 2004.
    Objective : The aim of the study was to identify factors affecting the survival of patients undergoing dialysis in the state of Pahang.
    Methods : Survival time was measured from the date of dialysis until the subjects died, lost to follow up or until the end of the study period at 31st December 2004.
    Results : Diabetes mellitus was the major cause for ESRD (33%) out of 132 subjects eligible for the study. Seven (7.1%) and five (15.2%) deaths occurred among haemodialysis and CAPD patients respectively, but statistically of no difference between the two treatments (log-rank, p=0.093). Factors influencing the survival of haemodialysis patients were diabetes mellitus (p=0.014), albumin (p=0.0005), creatinine (p=0.020) and hemoglobin level (p=0.002), while age of treatment and diabetes mellitus affecting the survival of CAPD patient. Cox Proportional Hazard Regression showed that haemodialysis subjects with low albumin (HR 0.669 df 95% 0.513 - 0.873) and hemoglobin (HR 0.403 df 95% 0.225 - 0.720) level had lower survival rate but none for CAPD.
    Conclusion : Good nutritional status, higher hemoglobin level and prevention of diabetes mellitus are important for the survival of haemodialysis patient.

    BACKGROUND: Early recognition of stroke-associated pneumonia (SAP) is critical to reducing morbidity and mortality associated with SAP. This study investigated the predictors of SAP, and the predictive value of the neutrophil percentage-to-albumin ratio (NPAR) for SAP.

    METHODS: This retrospective cohort study was conducted among stroke patients admitted to Jordan University Hospital from January 2015 to May 2021. Multivariable logistic regression was used to identify independent predictors for SAP. The predictive performance was assessed using C-statistics, described as the area under the receiver-operating characteristic curve (AUC, ROC) with a 95% confidence interval.

    RESULTS: Four hundred and six patients were included in the analysis, and the prevalence of SAP was 19.7%. Multivariable logistic analysis showed that males (Adjusted Odds Ratio (AOR): 5.74; 95% Confidence Interval (95%CI): 2.04-1 6.1)], dysphagia (AOR: 5.29; 95% CI: 1.80-15.5), hemiparesis (AOR: 3.27; 95% CI: 1.13-9.47), lower GCS score (AOR: 0.73; 95% CI: 0.58-0.91), higher levels of neutrophil-lymphocyte ratio (NLR) (AOR: 1.15; 95% CI: 1.07-1.24), monocyte-lymphocyte ratio (MLR) (AOR: 1.49; 95% CI: 1.13-1.96), and neutrophil percentage to albumin ratio (NPAR) (AOR: 1.53; 95% CI: 1.33-1.76) were independent predictors of SAP. The NPAR demonstrated a significantly higher AUC than both the NLR (0.939 versus 0.865, Z = 3.169, p = 0.002) and MLR (0.939 versus 0.842, Z = 3.940, p

    The clinical outcome of bacteraemic patients is influenced by many factors. It is vital to know one's own local hospital epidemiological data so as to provide optimal care to the affected patients. This was a prospective, observational study carried out in the said patient population over a period of four months in the year 2005. One hundred and ninety one patients presented with bacteraemia over the study period. Fifty-two (27%) of the patients died. Mechanical ventilation, inappropriate empirical antibiotic usage, Chinese ethnicity and low serum albumin levels independently affected prognosis. These factors should alert physicians to those patients who require more intensive monitoring and care.

    BACKGROUND: Bariatric surgery has been shown to improve and resolve diabetes. However, limited literature about its impact on end-organ complications of diabetes is available. The aim of this study was to examine the long-term effect of bariatric surgery on albuminuria.

    METHODS: We studied 101 patients with pre-operative diabetes and albuminuria [defined as urine albumin:creatinine ratio (uACR) > 30 mg/g] who underwent bariatric surgery at an academic center from 2005 to 2014.

    RESULTS: Fifty-seven patients (56%) were female with a mean age of 53 (± 11) years. The mean pre-operative BMI and glycated hemoglobin (HbA1c) were 43.1 (± 7.6) kg/m2 and 8.4 (± 1.8)%, respectively. The median pre-operative uACR was 80.0 (45.0-231.0) mg/g. Bariatric procedures included Roux-en-Y gastric bypass (n = 75, 74%) and sleeve gastrectomy (n = 26, 26%). The mean follow-up period was 61 (± 29) months. At last follow-up, the mean BMI was 33.8 (± 8.3) kg/m2. The overall glycemic control improved after bariatric surgery. At last follow-up, 73% had good glycemic control (HbA1c

    AIM: To study the prophylactic effect of recombinant Lactococcus lactis (rLl) harbouring Ara h 2.02 peanut allergen, in sensitized and challenged mice.

    METHODS AND RESULTS: Ara h 2.02 cDNA was cloned into pNZ8048 for heterologous expression in L. lactis. The purified recombinant allergen showed IgE binding comparable with native Ara h 2. Balb/c mice were fed with either recombinant (rLl), nonrecombinant L. lactis (Ll) or NaHCO3 (Sham) prior to sensitization and challenged with rAra h 2.02, whereas the baseline group was only fed with Ll. Allergen-specific immunoglobulin and splenocyte cytokines responses were determined for each mouse. Mice fed with either Ll or rLl showed significant alleviation of IgE and IgG1 compared to the Sham group. Despite no significant decrease in Th2 (IL-4, IL-13, IL-6) or increase in Th1 (IFN-γ) cytokines, both groups showed lower IL-10 level, while the IL-4 : IFN-γ ratio was significantly lower for rLl compared to Ll group.

    CONCLUSIONS: Oral administration of rLl harbouring Ara h 2.02 demonstrated alleviation of Th2-associated responses in allergen-challenged mice and a possible added allergen-specific prophylactic effect.

    SIGNIFICANCE AND IMPACT OF THE STUDY: Ara h 2.02 coupled with the intrinsic properties of probiotic L. lactis as a delivery vehicle can be explored for the development of a commercially scalable vaccine.

    Orthosiphon stamineus as medicinal plant is commonly used in Malaysia for treatment of hepatitis and jaundice; in this study, the ethanol extracts were applied to evaluate the hepatoprotective effects in a thioacetamide-induced hepatotoxic model in Sprague Dawley rats. Five groups of adult rats were arranged as follows: Group 1 (normal control group), Group 2 Thioacetamide (TAA) as positive control (hepatotoxic group), Group 3 Silymarin as a well-known standard drug (hepatoprotective group), and Groups 4 and 5 as high and low dose (treatment groups). After 60-day treatment, all rats were sacrificed. The hepatotoxic group showed a coarse granulation on the liver surface when compared to the smooth aspect observed on the liver surface of the other groups. Histopathological study confirmed the result; moreover, there was a significant increase in serum liver biochemical parameters (ALT, AST, ALP, and Bilirubin) and the level of liver Malondialdehyde (MDA), accompanied by a significant decrease in the level of total protein and Albumin in the TAA control group when compared with that of the normal group. The high-dose treatment group (200 mg/kg) significantly restored the elevated liver function enzymes near to normal. This study revealed that 200 mg/kg extracts of O. stamineus exerted a hepatoprotective effect.

    The current study aimed to investigate the ameliorative effects of two types of mushrooms, Ganoderma lucidum (GL) and Auricularia polytricha (AP), against carbofuran- (CF) induced toxicity in rats. Male Wistar rats (n = 42) were divided into six equal groups. The rats in the negative control group received oral administration of CF at 1 mg/kg with the normal diet for 28 days. The treatment groups received oral administration of ethanolic extract of GL or AP at 100 mg/kg followed by coadministration of CF at 1 mg/kg with the normal diet for the same experimental period, respectively. In the CF alone treated group, there were significant decreases in the erythrocytic and thrombocytic indices but increases in the concentrations of the total leukocytes, including the agranulocytes. A significant increase in all of the liver function biomarkers except albumin, in lipid profiles except high-density lipoprotein, and in the kidney function markers occurred in the negative control group compared to the rats of the normal control and positive control groups. The coadministration of mushroom extracts significantly ameliorated the toxic effects of the CF. The GL mushroom extract was more efficacious than that of the AP mushroom, possibly due to the presence of high levels of phenolic compounds and other antioxidants in the GL mushroom.

    This research aimed to determine the biofunctional properties of wheat flour (WF) protein fractions and modifications to the antioxidant, anti-α-amylase and anti-angiotensin-I converting enzyme (ACE) activities induced by the action of digestive endopeptidases in vitro. A molecular characterization of the most abundant protein fractions, i.e., albumins, glutelins-1, glutelins-2 and prolamins, showed that low- and high-MW polypeptides rich in cysteine, glutamic acid and leucine were present in albumins and glutelins, whereas low-MW subunits with a high proportion of polar amino acids prevailed in prolamins. Prolamins exhibited the second-highest water holding capacity (54%) after WF (84%), while albumins provided superior foam stability (76%). Prolamins, glutenins-1 and globulins demonstrated the highest antioxidant activity (up to 95%, 68% and 59%, respectively) both before and after hydrolysis with pepsin (P-H) or trypsin-chymotrypsin (TC-H). Prolamins, globulins and WF strongly inhibited α-amylase (>90%) before and after TC-H, and before P-H (55-71%). Moreover, P-H significantly increased α-amylase inhibition by albumins from 53 to 74%. The fractions with strong ACE inhibitory activity (70-89%) included prolamins and globulins after TC-H or P-H, as well as globulins before TC-H and WF before P-H. This novel evidence indicates that WF protein fractions and their peptide-enriched P and TC hydrolysates are excellent sources of multifunctional bioactives with antioxidant, antihyperglycemic and antihypertensive potential.

    Current diagnostic tools for peanut allergy using crude peanut extract showed low predictive value and reduced specificity for detection of peanut allergen-specific immunoglobulin E (IgE). The Ara h 2.02, an isoform of the major peanut allergen Ara h 2, contains three IgE epitope recognition sequence of 'DPYSPS' and may be a better reagent for component resolve diagnosis. This research aimed to generate a codon-optimised Ara h 2.02 gene for heterologous expression in Escherichia coli and allergenicity study of this recombinant protein. The codon-optimised gene was generated by PCR using overlapping primers and cloned into the pET-28a (+) expression vector. Moderate expression of a 22.5 kDa 6xhistidine-tagged recombinant Ara h 2.02 protein (6xHis-rAra h 2.02) in BL21 (DE3) host cells was observed upon induction with 1 mM isopropyl β-D-1-thiogalactopyranoside (IPTG). The insoluble recombinant protein was purified under denaturing condition using nickel-nitrilotriacetic acid (Ni-NTA) affinity chromatography and refolded by dialysis in decreasing urea concentration, amounting to a yield of 74 mg/l of expression culture. Matrix-assisted laser desorption/ionisation time-of-flight (MALDI-TOF) and immunoblot analysis confirmed the production of the recombinant 6xHis-rAra h 2.02. The refolded recombinant 6xHis-rAra h 2.02, with or without adjuvant, was able to elicit comparable level of allergen-specific IgE and IgG1 in sensitised Balb/c mice. In addition, the specific IgE antibodies raised against the recombinant protein were able to recognise the native Ara h 2 protein, demonstrating its allergenicity and potential as a reagent for diagnosis and therapeutic study.

    OBJECTIVE: To evaluate current evidence on the efficacy and safety of Cordyceps sinensis (cordyceps) or its fermented products used as an adjunctive treatment in patients undergoing maintenance hemodialysis.

    METHODS: The Cochrane Central Register of Controlled Trials (CENTRAL), EMBASE, MEDLINE, China National Knowledge Infrastructure (CNKI) and Wanfang Database were searched for relevant randomized controlled trials up to March 2016. Two review authors independently selected trials for inclusion, extracted data, assessed the methodological quality and rated the quality of evidence with the Grading of Recommendations, Assessment, Development and Evaluation approach.

    RESULTS: Twelve studies involving 655 participants were included. Evidence of low to moderate-quality showed that cordyceps plus conventional treatment compared to conventional treatment alone significantly improved C-reactive protein [standardized mean difference (SMD) -0.61; 95% confidence intervals (CI) -1.00 to -0.22], high-sensitivity C-reactive protein [weighted mean difference (WMD) -3.44 mg/L; 95% CI -3.89 to -2.99], serum albumin (WMD 3.07 g/L; 95% CI 1.59 to 4.55), malondialdehyde (WMD -1.95 nmol/L; 95% CI -2.24 to -1.66), and hemoglobin (WMD 9.56 g/L; 95% CI 3.65 to 15.47) levels. However, there was no significant improvement for serum creatinine and low-density lipoprotein cholesterol. Overall, most trials either did not monitor adverse events or poorly documented them.

    CONCLUSION: Given the small number of trials included, the unclear methodological quality of the included trials, and the high heterogeneity in pooled analyses, the evidence obtained in this review is insufficient to recommend the use of cordyceps as adjunctive treatment in hemodialysis patients.

Methods: A systematic review was done of several databases and a meta-analysis with a random-effects model was conducted to assess the efficacy and safety of nab-paclitaxel in metastatic gastric cancer (MGC). Results: Included studies revealed that nab-paclitaxel provides a 30.4% overall response rate and 65.7% disease control rate in MGC patients. The overall survival was 9.65 months and progression-free survival was 4.48 months, associated with the treatment line and regimen. The highest incidence of grade 3 and higher treatment-related adverse events was for neutropenia (29.9%). Conclusion: Nab-paclitaxel provides better disease response and longer survival with manageable side effects in MGC compared with paclitaxel.

    Ber e 1, a major Brazil nut allergen, has been successfully produced in the yeast Pichia pastoris expression system as homogenous recombinant Ber e 1 (rBer e 1) with similar physicochemical properties and identical immunoreactivity to its native counterpart, nBer e 1. However, O-linked glycans was detected on the P.pastoris-derived rBer e 1, which is not naturally present in nBer e 1, and may contribute to the allergic sensitisation. In this study, we addressed the glycosylation differences between P. pastoris-derived recombinant Ber e 1 and its native counterparts. We also determined whether this fungal glycosylation could affect the antigenicity and immunogenicity of the rBer e 1 by using dendritic cells (DC) as an immune cell model due to their role in modulating the immune response. We identified that the glycosylation occurs at Ser96, Ser101 and Ser110 on the large chain and Ser19 on the small polypeptide chain of rBer e 1 only. The glycosylation on rBer e 1 was shown to elicit varying degree of antigenicity by binding to different combination of human leukocyte antigens (HLA) at different frequencies compared to nBer e 1 when tested using human DC-T cell assay. However, both forms of Ber e 1 are weak immunogens based from their low response indexes (RI). Glycans present on rBer e 1 were shown to increase the efficiency of the protein recognition and internalization by murine bone marrow-derived dendritic cells (bmDC) via C-type lectin receptors, particularly the mannose receptor (MR), compared to the non-glycosylated nBer e 1 and SFA8, a weak allergenic 2S albumin protein from sunflower seed. Binding of glycosylated rBer e 1 to MR alone was found to not induce the production of IL-10 that modulates bmDC to polarise Th2 cell response by suppressing IL-12 production and DC maturation. Our findings suggest that the O-linked glycosylation by P. pastoris has a small but measurable effect on the in vitro antigenicity of the rBer e 1 compared to its non-glycosylated counterpart, nBer e 1, and thus may influence its applications in diagnostics and immunotherapy.
