Abstract
Honey bee venom is a valuable product with a wide range of biological effects, whose use is rapidly increasing in apitherapy. In this study, the effect of gamma-irradiated honey bee venom (doses of 0, 2, 4, 6, and 8 kGy, volume of 0.1 ml, and concentration of 0.2 mg/ml) was evaluated on median lethal dose (LD50) determinations, liver and kidney histology, biochemical marker level, and serum protein analyses. Hence, the LD50 induced by the honey bee venom irradiated at 4, 6, and 8 kGy was increased, compared with the one at 0 and 2 kGy. Normal histology was observed in the liver and kidney of the mice receiving the honey bee venom irradiated at 4, 6, and 8 kGy. The serum levels of alanine aminotransferase (ALT) and all serum proteins were reduced at 4, 6, and 8 kGy compared with 0 and 2 kGy. Therefore, gamma irradiation at 4, 6, and 8 kGy had no negative effect on LD50, liver and kidney tissues, ALT, and serum protein levels by decreasing the allergen compounds of the honey bee venom.

Abstract
Early detection of noise-induced hearing loss (NIHL) in patients with long-term noise exposure is vital for improving public health and reducing social burden. However, at present, the diagnosis of NIHL mainly depends on audiometric testing, and the primary test is pure-tone audiometry. Moreover, testing requires professional operators and complex equipment; thus, NIHL is often diagnosed at a later disease stage. Using a liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based proteomic approach, we identified 9 differentially expressed proteins (DEPs), namely, 6 upregulated serum proteins and 3 downregulated serum proteins, in samples from 50 ground crew personnel working at an air force station. Then, according to the results, we predicted that caldesmon (CALD1), myocilin (MYOC), zyxin (ZYX), creatine kinase M-type (CKM), insulin-like growth factor-binding protein 2 (IGFBP2), complement factor H-related protein 4 (CFHR4), prenylcysteine oxidase 1 (PCYOX1), heat shock cognate 71 kDa protein (HSPA8), and immunoglobulin lambda variable 3-21 (IGLV3-21) were associated with NIHL. We selected these DEPs as variables to perform logistic regression. Finally, a logistic regression model was constructed based on IGFBP2, ZYX, CKM, and CFHR4. The area under the curve was 0.894 (95% CI = 0.812 to 0.977). These findings suggested that IGFBP2, ZYX, CKM, and CFHR4 in serum are differentially expressed in NIHL patients and have the potential to be biomarkers for predicting the risk for NIHL. Further experiments in mice showed that ZYX and IGFBP2 in the cochlear were increased after noise exposure. ZYX and IGFBP2 may be involved in the occurrence and development of NIHL.

Abstract
While the link between serum proteins and cancer has been studied in an effort to enable early-stage cancer detection, factors that might perturb this link has been poorly understood. To ask this question, we performed serum protein profiling on a prospective cohort of 601 individuals with or without lung, pancreatic, or colorectal cancers and identified ten distinct serum protein signatures with distinct link to the patient metadata. Importantly, we discovered that a positive history of alcohol consumption is a major factor that diminishes the sensitivity of serum protein-mediated liquid biopsy in early-stage malignancies, resulting in a 44% decline in the sensitivity of detecting American Joint Committee on Cancer (AJCC) stage I malignancies. Our data provide evidence that patient lifestyle can affect the sensitivity of liquid biopsy and suggest the potential need for abstinence from alcohol before measurement during serum protein-based cancer screening.

Abstract
Serum protein is generally used to assess the severity of disease, as well as cancer progression and prognosis. Herein, a simple and rapid serum proteins analysis method combined with surface-enhanced Raman spectroscopy (SERS) technology was applied for breast cancer detection. The cellulose acetate membrane (CA) was employed to extract human serum proteins from 30 breast cancer patients and 45 healthy volunteers and then extracted proteins were mixed with silver nanoparticles for SERS measurement. Additionally, we also mainly assessed the use of different ratios of proteins-silver nanoparticles (Ag NPs) mixture to generate maximum SERS signal for clinical samples detection. Two multivariate statistical analyses, principal component analysis-linear discriminate analysis (PCA-LDA) and partial least square-support vector machines (PLS-SVM) were used to analyze the obtained serum protein SERS spectra and establish the diagnostic model. The results demonstrate that the PLS-SVM model provides superior performance in the classification of breast cancer diagnosis compared with PCA-LDA. This exploratory work demonstrates that the label-free SERS analysis technique combined with CA membrane purified serum proteins has great potential for breast cancer diagnosis.

Abstract
Serum protein as naturally essential biomacromolecules has recently emerged as a versatile carrier for diagnostic and therapeutic drug delivery for cancer nanomedicine with superior biocompatibility, improved pharmacokinetics and enhanced targeting capacity. A variety of serum proteins have been utilized for drug delivery, mainly including albumin, ferritin/apoferritin, transferrin, low-density lipoprotein, high-density lipoprotein and hemoglobin. As evidenced by the success of paclitaxel-bound albumin nanoparticles (AbraxaneTM), serum protein-based nanoparticles have gained attractive attentions for precise biological design and potential clinical application. In this review, we summarize the general design strategies, targeting mechanisms and recent development of serum protein-based nanoparticles in the field of cancer nanomedicine. Moreover, we also concisely specify the current challenges to be addressed for a bright future of serum protein-based nanomedicines.

Abstract
Lipid emulsions are potential carriers for poorly water-soluble drugs. Previously, we revealed that lipid nanoparticles complexed with styrene maleic acid copolymer (SMA) disintegrate under acidic pH. In the present study, SMA-containing lipid emulsions (SMA emulsions) were prepared and their physicochemical and biological properties were examined to test whether SMA emulsions could be used as a trigger to facilitate drug release in response to pH reduction. By sonicating lipid and SMA mixtures, homogeneously sized SMA emulsion particles were prepared as verified via dynamic light scattering and transmission electron microscopy. Upon the reduction of solution pH, disintegration of SMA emulsions was observed, which may be utilized for drug release at mildly acidic pH. In addition, the sensitivity to pH changes could be controlled by altering the lipid composition. Serum proteins bound to SMA emulsions were analyzed to predict the metabolic fate upon intravenous injection. Predictably, apolipoproteins were abundantly bound, suggesting that SMA emulsions should avoid being recognized as foreign substances. Furthermore, subcellular distribution studies using a human breast cancer cell line (MDA-MB-231) demonstrated that SMA emulsions localize to lysosomes, which have a lower pH. These results suggest that SMA emulsions could be promising pH-responsive drug carriers.

Abstract
Background Paper-analytical devices (PADs) have gained popularity as a simple and low-cost alternative for determining a wide range of analytes including proteins. Even though several colorimetric PADs methods for protein estimation are reported in literature, they lack justification for the chosen method and parameters therein. Aim Major aim of this work was to thoroughly evaluate the most commonly used colorimetric protein assays and recommend the most appropriate method for PADs platform. Method We performed following six colorimetric protein assays on PADs: biuret, lowry, bicinchoninic acid, bradford, bromocresol green, and tetrabromophenol blue. We obtained assay signal by analyzing images of the PADs and then assessed analytical figures of merit. Result Precision, accuracy, LOD, and LOQ of PADs protein assay methods ranged from 1.2 to 6.4%, 73.3–102.4%, 0.3–3.8 mg/mL, and 1.2–12.8 mg/mL, respectively. Out of six methods, we determined bromocresol green and tetrabromophenol blue as the best methods for serum and urine samples, respectively based on their optimized parameters and analytical figures of merit. The total average serum and urine protein in human samples were found to be 94.6 ± 16.2 mg/mL and 2.1 ± 1.5 mg/mL, respectively using PADs methods. The PADs result on human samples moderately correlated with the results from spectrophotometric determination (r2 > 0.6). Conclusion Paper-based protein assays were easy to perform and were completed with thousand-fold less volume of samples/reagents without a spectrophotometer compared to conventional assay methods. After testing human samples, we found one protein assay method may not be appropriate for all types of samples. Thorough evaluation of colorimetric protein assays on paper-analytical device. Bromocresol green and tetrabromophenol blue methods were found to be best suited for serum and urine samples, respectively. The selected methods are comparable with spectrophotometric assay protocols for human serum and urine samples.

Abstract
The aim of this pilot study was to analyze the serum proteomic profile of women suffering from menstrual-related migraine (MM group, n = 15) and migraine in post-menopause (PM group, n = 15) in comparison with non-headache control females (C group, n = 15). Serum samples were subjected to two-dimensional gel electrophoresis (2-DE) followed by mass spectrometry (MS) analysis for protein identification. Based on 2D-gel maps and PDQuest 2-D software, 13 differentially expressed spots, corresponding to 12 unique proteins identified by Liquid Chromatography-Electrospray Ionization-Quadrupole-Time of Flight/tandem mass spectrometry (LC-ESI-QToF-MS/MS), were detected in the MM and PM groups vs C group. Five inflammatory and regulatory of vascular integrity proteins (prothrombin, serum amyloid P-component, Ig kappa chain C region, apolipoprotein A-I, serum amyloid A-4 protein) were found deregulated in both MM and PM groups compared to C group; MM group showed the upregulation of other inflammatory protein fragments (inter-alpha-trypsin inhibitor heavy chain H4 and complement C4-A) compared to C group; PM group, in comparison with C group, displayed a noteworthy upregulation of transthyretin and other deregulated proteins (tetranectin, alpha-1-antitrypsin, haptoglobin, apolipoprotein A-IV) playing a role in anti-inflammatory and reparative processes. In conclusion, proteomic analysis was able to reveal differences in protein expression between migraine sufferers and non-headache women; as in other neurological diseases characterized by neuroinflammation, the serum proteome of migraine women presents an abundance of proteins indicative of cellular damage, oxidative stress and inflammation. This relevant inflammatory status, if confirmed in larger series, could represent a target for menstrual-related migraine treatment.

Abstract
Blood components are considered to reflect nutrient metabolism and immune activity in both humans and animals. In this study, we measured 12 blood components in Pekin ducks and performed genome-wide association analysis to identify the QTLs (quantitative trait locus) using a genotyping-by-sequencing strategy. A total of 54 QTLs were identified for blood components. One genome-wide significant QTL for alkaline phosphatase was identified within the intron-region of the OTOG gene (P = 1.31E-07). Moreover, 21 genome-wide significant SNPs for the level of serum cholinesterase were identified on six different scaffolds. In addition, for serum calcium, one genome-wide significant QTL was identified in the upstream region of gene RAB11B. These results provide new markers for functional studies in Pekin ducks, and several candidate genes were identified, which may provide additional insights into specific mechanisms for blood metabolism in ducks and their potential application for duck breeding programs.

Abstract
PURPOSE It has been reported that oral valproate (VPA) reduces the dose of propofol required for sedation. As a potential reason for this, it is considered that VPA displaces serum protein-bound propofol and increases the proportion of protein-unbound-free propofol. To examine this hypothesis, the present in vitro study investigated the influence of VPA on the proportion of protein-unbound-free propofol in human serum samples. METHODS Serum samples were collected from 10 healthy volunteers, who were not taking any medication. VPA (final concentration: 0.05, 0.1 or 1 mg/mL) and propofol (final concentration: 1 or 5 µg/mL) were mixed with serum samples with normal (4.0 g/dL) or low (2.5 g/dL) albumin concentrations. Then, protein-unbound-free propofol was extracted from the samples, and its concentration was measured using high-performance liquid chromatography. We compared the proportion of protein-unbound-free propofol in each of the VPA-containing samples with that in serum samples without VPA (control). RESULTS In the serum samples with normal albumin concentrations, 1 mg/mL VPA significantly increased the proportion of protein-unbound-free propofol at 1 and 5 µg/mL propofol. Furthermore, in the serum samples with low albumin concentrations, the proportion of protein-unbound-free propofol was significantly increased by both 0.1 and 1 mg/mL VPA at propofol concentrations of 1 and 5 µg/mL. CONCLUSION VPA might increase the proportion of protein-unbound-free propofol in human serum via displacement reactions.

Abstract
This research aimed to discover potential biomarkers for evaluating the therapeutic efficacy of intensive therapy in pulmonary tuberculosis (TB). Protein profiles in 2-months intensively treated TB patients, untreated TB patients, and healthy controls were investigated with iTRAQ-2DLC-MS/MS technique. 71 differential proteins were identified in 2-months intensively treated TB patients. Significant differences in complement component C7 (CO7), apolipoprotein A-IV (APOA4), apolipoprotein C-II (APOC2), and angiotensinogen (ANGT) were found by ELISA validation. CO7 and ANGT were also found significantly different in sputum negative patients, compared with sputum positive patients after intensive treatment. Clinical analysis showed that after 2-months intensive treatment several indicators were significantly changed, and the one-year cure rate of sputum negative patients were significantly higher than sputum positive patients. Diagnostic models consisting of APOC2, CO7 and APOA4 were established to distinguish intensively treated TB patients from untreated TB patients and healthy controls with the AUC value of 0.910 and 0.935. Meanwhile, ANGT and CO7 were combined to identify sputum negative and sputum positive TB patients after intensive treatment with 89.36% sensitivity, 71.43% specificity, and the AUC value of 0.853. The results showed that APOC2, CO7, APOA4, and ANGT may be potential biomarkers for evaluating the efficacy of intensive anti-TB therapy.

Abstract
It has been demonstrated that human serum albumin (HSA) directly interacts with AAV virions and enhances AAV transduction. Several other proteins have also been identified a potential for enhancing AAV8 liver transduction. In our study, LDL or transferrin could enhance transduction in vitro and in vivo. We also found that any combination of two or three of these proteins (HSA, LDL, and transferrin) increased AAV8 transduction in Huh7 cells and in mice liver, which was similar to albumin alone. Pre-incubation of HSA with AAV8 virions prevented AAV8 virions from binding to other proteins. Furthermore, these serum protein receptors didn't impact AAV8 transduction but blocked the transduction enhancement from AAV8-serum protein complexes. These results indicate that serum proteins are hijacked by AAV8 vectors to increase hepatocyte binding, which shares same binding site. Importantly, the results could help us design an optimal formulation for effective AAV vector delivery in future clinical trials.

Abstract
BACKGROUND Numerous studies have suggested that an immune system imbalance plays an important role in schizophrenia. Macrophage migration inhibitory factor (MIF) is a pleiotropic cytokine. It plays multiple roles in various biological processes, including inflammation and neurogenesis. Furthermore, several exhaustive serum proteomic profiling studies have identified MIF as a potential biomarker of schizophrenia. Here, we investigate MIF protein levels in serum and postmortem prefrontal cortex in patients with schizophrenia and controls. Moreover, we investigate the association of two functional polymorphisms in the MIF gene promoter region (MIF-794CATT5-8 microsatellite and MIF-173G/C single-nucleotide polymorphism [SNP]) with schizophrenia. METHODS We measured serum MIF levels with an enzyme-linked immunosorbent assay (ELISA) (51 patients vs. 86 controls) and postmortem brain MIF levels with a western blotting assay (18 patients vs. 22 controls). Subsequently, we genotyped the MIF-794CATT5-8 microsatellite with a fluorescence-based fragment assay and the MIF-173G/C SNP with a TaqMan SNP genotyping assay (1483 patients vs. 1454 controls). RESULTS Serum MIF levels were significantly higher in patients with schizophrenia than in controls (p=0.00118), and were positively correlated with antipsychotic dose (Spearman's r=0.222, p=0.0402). In addition, an earlier age of onset was observed in patients with a high serum MIF level (≥40ng/mL) than those with a low serum MIF level (<40ng/mL) (p=0.0392). However, postmortem brain MIF levels did not differ between patients with schizophrenia and controls. The association study revealed that the CATT6-G haplotype was nominally significantly associated with schizophrenia (p=0.0338), and that the CATT6 allele and CATT6-G haplotype were significantly associated with female adolescent-onset schizophrenia (AsOS) (corrected p=0.0222 and p=0.0147, respectively). CONCLUSIONS These results suggest that serum MIF level is a potential pharmacodynamic and/or monitoring marker of schizophrenia, and is related to a novel antipsychotic effect beyond dopamine antagonism. Furthermore, the MIF gene polymorphisms are associated with the risk for schizophrenia especially in adolescent females, and are potential stratification markers of schizophrenia. Further studies of MIF are warranted to elucidate the pathophysiology of schizophrenia and the effects of antipsychotics.

Abstract
Perfluorinated chemicals (PFCs) have been used widely in consumer products manufacture. Recent in vitro as well as animal studies have found that there are different toxicity and pharmacokinetic profiles between isomers of perfluorooctanoic acid (PFOA) and/or perfluorooctane sulfonate (PFOS). However, the differential effects of linear or branched PFOA/PFOS isomers on human beings have never been reported. Herein, we examined 1871 adult subjects (age older than 18 years) from the National Health and Nutrition Examination Survey (NHANES) 2013-2014 to determine the association between the isomers of PFOA/PFOS and serum biochemistry profiles, including glucose, lipids, protein and components of metabolic syndrome (MS). The results showed that for PFOA, increased linear PFOA was associated with increases in total cholesterol, serum albumin and an enhancement of β cell function as well as a decrease in the serum globulin. Increased branched PFOA was significantly associated with increased fasting glucose. All isomers of PFOA were positively associated with high-density lipoprotein-cholesterol (HDL-C) and negatively associated with glycohemoglobin (HbA1C). The branched PFOS was positively associated with β cell function and inversely associated with serum globulin. Both linear and branched isomers of PFOS were positively associated with the total protein and albumin. The increased branched PFOA was associated with less HDL-C insufficiency defined by the National Cholesterol Education Program Third Adult Treatment Panel (NCEP-ATP III) MS criteria, whereas the increased concentrations of serum total and linear PFOS were associated with less hypertriglyceridemia by the NCEP-ATP III. In conclusion, serum isomers of PFOA and PFOS were associated with glucose homeostasis, serum protein as well as lipid profiles; they were also indicators of MS. This may suggest that there is a distinct difference in the toxicokinetics of the isomers of PFOA and PFOS. Further clinical and animal studies are warranted to clarify the putative causal relationships between isomers and biochemical alterations.

Abstract
The aim of this retrospective study was to identify the major risk factors associated with case fatality in diarrhoeic calves undergoing a standard therapeutic protocol. Clinical and laboratory findings were reviewed in 225 Holstein Friesian diarrhoeic calves over a 2 year period. Calves were treated according to a fluid therapy protocol using an oral electrolyte solution or an IV infusion. After therapy, 159 calves were discharged in a healthy state, whereas 66 calves died. Logistic regression analysis showed that serum total protein (STP) concentration (odds ratio, OR, 0.51; 95% confidence interval, CI 0.31-0.84; P<0.01) and the strength of suckle reflex (OR 4.83; CI 1.17-19.88; P<0.05) were the major risk factors associated with case fatality in diarrhoeic calves. These results could help to distinguish between diarrhoeic calves with a good prognosis and those with a major risk of treatment failure.

Abstract
Age-related macular degeneration (AMD), in which choroidal neovascularization (CNV) affects the center of the retina (macula), leads to the irreversible visual loss. The intravitreal injection of anti-angiogenesis antibodies improved the prognosis of AMD, but relatively less invasive therapies should be explored. In the present study, we show that a high-density lipoprotein (HDL) mutant is a therapeutically active drug carrier capable of treating a posterior eye disease in mice via instillation. Various HDL mutants were prepared with apoA-I proteins fused with different cell-penetrating peptides (CPPs) and phospholipids with different alkyl chain lengths; their sizes were further controlled in the range of 10-25nm. They were screened based on the efficiency of fluorescent dye delivery to the inner retinal layer in mice. The best mutant was found to have penetratin (PEN) as a CPP, 1,2-distearoyl-sn-glycero-3-phosphocholine (DSPC), and a size of 15nm. In preclinical studies on a laser-induced CNV murine model, 1week of instillation of the best mutant carrying the anti-angiogenesis drug pazopanib had dramatic therapeutic effects in reducing the CNV size. Importantly, the HDL mutant by itself contributed to the therapeutic effects. Future clinical trials for treating AMD with instillation of the HDL mutant are expected.

Abstract
INTRODUCTION In carcinogenesis, increased oxidative stress and weakened antioxidant defense produces damage to the macromolecules like proteins. Thus, protein can act as potential biomarker in oral premalignant and malignant lesions. AIM To determine and compare the levels of serum proteins in Oral Submucuous Fibrosis (OSMF), Oral Leukoplakia (OL), Nicotina Stomatitis (NS), Oral Malignancy (OM) and Healthy Controls (HC). MATERIALS AND METHODS A total of 250 participants, were equally divided in five groups i.e., OSMF, OL, NS, OM and HC. Five ml of blood was collected from antecubital vein from each participant. The serum was analyzed for total protein, albumin and globulin levels using EBRA EM 200 semi-quantitive analyzer with the help of diagnostic kits. RESULTS There were total 193 males and 57 females, who were between 18 to 82 years of age, with a mean of 46.32±13.89 years. The serum protein and globulin levels were significantly decreased in OSMF, OL and NS and increased in OM as compared to HC (p<0.001). No statistically significant difference was found in serum albumin levels between the study groups (p>0.05). CONCLUSION Serum proteins can be used as diagnostic and prognostic marker for oral premalignant and malignant lesions.

Abstract
We have reviewed the conjugation of biogenic polyamines spermine (spm), spermidine (spmd) and synthetic polyamines 3,7,11,15-tetrazaheptadecane.4HCl (BE-333) and 3,7,11,15,19-pentazahenicosane.5HCl (BE-3333) with human serum albumin (HSA), bovine serum albumin (BSA) and milk beta-lactoglobulin (b-LG) in aqueous solution at physiological pH. The results of multiple spectroscopic methods and molecular modeling were analysed here and correlations between polyamine binding mode and protein structural changes were estabilished. Polyamine-protein bindings are mainly via hydrophilic and H-bonding contacts. BSA forms more stable conjugates than HSA and b-LG. Biogenic polyamines form more stable complexes than synthetic polyamines except in the case of b-LG, where the protein shows more hydrophobic character than HSA and BSA. The loading efficacies were 40-52%. Modeling showed the presence of several H-bonding systems, which stabilized polyamine-protein conjugates. Polyamine conjugation induced major alterations of serum protein conformations. The potential application of serum proteins in delivery of polyamines is evaluated here.

Abstract
Due to the poor solubility of steroids in aqueous solution, delivery of these biomaterials is of major biomedical importance. We have reviewed the conjugation of testosterone and it aliphatic dimer and aromatic dimer with several carrier proteins, human serum albumin (HSA), bovine serum albumin (BSA) and milk beta-lactoglobulin (b-LG) in aqueous solution at physiological pH. The results of multiple spectroscopic methods, transmission electron microscopy (TEM) and molecular modeling were compared here. Steroid-protein bindings are via hydrophilic and H-bonding contacts. HSA forms more stable conjugate than BSA and b-LG. The stability of steroid-protein conjugates is testosterone>dimer-aromatic>dimer-aliphatic. Encapsulation of steroids by protein is shown by TEM images. Modeling showed the presence of H-bonding, which stabilized testosterone-protein complexes with the free binding energy of -12.95 for HSA and -11.55 for BSA and -8.92kcal/mol for b-LG conjugates. Steroid conjugation induced major perturbations of serum protein conformations. Serum proteins can transport steroids to the target molecules.

Background In this study, we sought to identify definitive biomarkers associated with disease activity in primary Sjögren’s syndrome (pSS). Methods Serum protein concentrations in pSS patients and healthy controls (HCs) were comprehensively screened using high-throughput proteomic analysis, and differentially expressed proteins were extracted. Correlation between differentially expressed proteins and European League Against Rheumatism Sjögren’s Syndrome Disease Activity Index (ESSDAI) scores was analyzed and disease activity-associated biomarkers were identified. These biomarkers were validated by enzyme-linked immunosorbent assay (ELISA) in a separate pSS cohort. Results The serum concentrations of 1100 proteins were compared between 30 pSS patients and 30 HCs, with 82 differentially expressed proteins identified as pSS-associated proteins. Of these 82 proteins, 9 were identified as disease activity-associated biomarkers. These nine biomarkers underwent validation by ELISA in a separate pSS validation cohort (n = 58), with five proteins (CXCL13, TNF-R2, CD48, B-cell activating factor (BAFF), and PD-L2) subsequently being confirmed as candidate biomarkers. Of these five candidate biomarkers, CXCL13 exhibited the most significant correlation with the lymphadenopathy, glandular, and pulmonary domains of the ESSDAI. CXCL13, TNF-R2 and CD48 exhibited a positive correlation with the biological domain of the ESSDAI. TNF-R2 exhibited the most negative correlation with uptake in the submandibular gland on technetium 99m-pertechnetate salivary gland scintigraphy. Conclusions Our approach successfully identified serum biomarkers associated with disease activity in pSS patients. These markers might be potential therapeutic targets in pSS patients.

Abstract
FERM domain is upregulated in P. berghei infected host serum. FERM domain has several protein partners to provide a link in cytoskeleton signals. FERM domain is recognized by erythrocyte cytoskeleton associated proteins like MESA and PHIST. We predict that FERM domain is involved in the merozoites entry and protein trafficking.
Malaria continues to affect 500 million people worldwide every year. In this study, we compared the protein profile of uninfected and Plasmodium berghei-infected serum samples by one dimensional SDS-PAGE analysis, MALDI-TOF/TOF mass spectrometry and confirmed by semi-quantitative RT-PCR. Also the protein interacting networks were established using STRING proteinprotein interaction analysis. We observed for the first time the upregulation of FERM domain during P. berghei infection. We predict that FRMD5 along with the other protein partners (identified by STRING analysis) are involved in the merozoites entry or protein trafficking where cell to cell interaction happens with the host erythrocyte; hence, upregulation.

Abstract
We used surface plasmon resonance (SPR) to measure the affinity and kinetics of the interaction between serum proteins and both conventional and PEGylated liposomes. The effect of the interactions on secretory phospholipase A2 (sPLA2)-induced release of a model drug from liposomes was also assessed. SPR analysis of 12 serum proteins revealed that the mode of interaction between serum proteins and liposomes greatly varies depending on the type of protein. For example, albumin bound to liposomes at slower association/dissociation rates with higher affinity and prevented sPLA2-induced drug release from PEGylated liposomes. Conversely, fibronectin bound at faster association/dissociation rates with lower affinity and demonstrated little impact on the drug release. These results indicate that the effect of serum proteins on sPLA2 phospholipid hydrolysis varies with the mode of interaction between proteins and liposomes. Understanding how the proteins interact with liposomes and impact sPLA2 phospholipid hydrolysis should aid the rational design of therapeutic liposomal formulations.

Abstract
We recently developed a system for coating polystyrene (PS) substrates with hydroxyapatite (HAp) by utilizing serum protein adsorption layers as mediators to induce the heterogeneous nucleation of HAp in simulated body fluids (SBFs). In this study, the selective deposition of HAp on polymer substrate surfaces with different protein adsorption abilities was investigated using PS and poly(methyl methacrylate) (PMMA). Atomic force microscopic observations and the results of a quantitative analysis using a quartz-crystal microbalance (QCM) revealed that the amounts of proteins such as human serum albumin (HSA) and human immunoglobulin G (hIgG) adsorbed on PS substrate surfaces were markedly greater than those on PMMA substrate surfaces. A markedly larger amount of HAp was deposited on protein-treated PS substrate surfaces than on PMMA substrate surfaces, reflecting protein adsorption to polymers. We also revealed that the deposition of HAp on protein-adsorbed PS substrate surfaces was enhanced by aqueous calcium chloride treatments before immersion in 1.5SBF. In the case of 2.5 M calcium chloride treatment, these surfaces were completely covered with deposits.

Abstract
BACKGROUND POSSUM was developed to predict risk-adjusted mortality and morbidity rates for surgical procedures. We evaluated the impact of serum albumin and serum protein levels on POSSUM scores. METHODS Medical files of 2269 patients operated for proximal femur fractures were reviewed. Preoperative serum albumin levels were available for 387 patients (mean 35.1g/l, range 22-49) and serum protein levels for 279 patients (mean 61.6g/l, range 40-86). RESULTS Serum albumin and protein levels were inversely associated with mortality in multivariate models (albumin, OR=0.89, p=0.009; protein, OR=0.92, p=0.009) and in composite outcome models as well (albumin, OR=0.955, p=0.219, protein, OR=0.94, p=0.014). The area under the curve (AUC) for POSSUM prediction of mortality (n=1770) was 0.632 (95% CI: 0.580-0.684, p<0.001). The AUC for a model including serum protein levels was 0.742 (95% CI: 0.649-0.834, p<0.001). Hospitalisation time was longer for patients with lower serum proteins levels (p=0.045), with an inverse correlation (Pearson correlation -0.164, p=0.011). CONCLUSIONS Lower preoperative serum albumin and serum protein levels were associated with increased risk for mortality, increased hospitalisation time and poorer outcomes in patients operated for proximal femoral fractures. Including those values to POSSUM scores would increase their predictive power.

Abstract
[Purpose] To investigate the correlation between the effect treadmill exercise and
change in serum proteins in rats with osteoarthritis, a study of proteins was carried out
using a mass spectrometer. [Subjects and Methods] Rats were randomly divided into five
groups. After 4 weeks of treadmill training, serum from each rat was analyzed by Liquid
chromatography-electrospray ionization tandem mass spectrometry. Complementary component 9
(C9) was discovered to be downregulated in the serum of the exercise groups, and this was
validated by Western blot. [Results] Seventeen proteins were discovered to be elevated in
the monosodium iodoacetate injection osteoarthritis group samples by more than 1.5 fold
compared with the control group. One of the proteins upregulated, C9 protein, was
validated, and it was found to decrease in the middle-intensity exercise group.
[Conclusion] We showed that the serum level of C9, an inflammatory-related protein,
decreased after treadmill exercise. Therefore, treadmill exercise with an appropriate
intensity might be recommended for OA patients.

Abstract
In this study the effects of water salinity on serum total protein and its components in grass carp were investigated. The aim of this study was to determine the effect of salinity tolerance of fish on total serum protein level and its components as an indicator of liver and kidney activity. One hundred and twenty grass carp were divided into four groups, randomly. The first three groups were reared in concentration of 4, 8 and 12 g L(-1) of salt solution, respectively, and the fourth group was reared in freshwater and served as control. After 3 weeks, blood samples were collected and after harvesting the blood serum, serum total protein and protein components were measured with Biuret and electrophoresis methods, respectively. Results showed that mean value of serum total protein in the control and three salinities groups were 2.75, 3.28, 2.90 and 3.13 g dL(-1), respectively. Five fractions of serum protein were electrophoretically observed as: albumin (Alb), alpha-1 globulin (α1-glu), alpha-2 globulin (α2-glu), beta globulin (β-glu) and gamma globulin (γ-glu). There were not any significant differences between the average mean of serum total protein of experimental and control groups (p > 0.05). However, Alb, α1-glu and β-glu levels in the experimental groups were significantly higher than in the control group (p < 0.05). The average of α2-glu and γ-glu revealed no significant difference between the experimental groups (p > 0.05). In conclusion, our results showed that increasing water salinity could have a significant effect on Alb, α1-glu and β-glu levels but not on total serum protein in grass carp.

Abstract
Protobothrops flavoviridis serum proteins precipitated with ammonium sulfate were chromatographed on a DEAE-Toyopearl 650M column at pH 7.5 with stepwise increase or with linear gradient of NaCl concentration. Peaks 3 and 4 serum proteins, obtained by linear gradient elution and named Fr(de3) and Fr(de4), contained Habu serum factors (HSF) and phospholipase A2 (PLA2) inhibitors (PfPLI), respectively. The serum proteins eluted at 0.2 M NaCl by stepwise elution, named Fr(0.2NaCl), effectively suppressed myonecrosis and hemorrhage caused by P. flavoviridis venom in rat or mouse thigh muscles. The Fr(0.2NaCl) were fractionated by HPLC and the fractions, after SDS-PAGE, underwent far-western blot analysis with PLA2 ([Asp(49)]PLA2) and BPI ([Lys(49)]PLA2) as the probes. Four PfPLIs, namely, PfαPLI-A, PfαPLI-B, PfγPLI-A and PfγPLI-B, were identified together with their selective binding specificities to PLA2 species. In addition, a new 9 kDa protein, which is specifically bound to BPI, was found. Suppression of P. flavoviridis venom-induced severe lesions, such as myonecrosis, hemorrhage and edema, with its serum proteins was histopathologically observed in the present work for the first time. The cooperative use of P. flavoviridis antivenom and its serum proteins as medication for P. flavoviridis snake bites is discussed.

Abstract
Monoclonal free light chains (FLCs) are important disease biomarkers in patients with plasma cell-proliferative disorders. The increasing evidence for clonal diversity and evolution in multiple myeloma highlights the importance of laboratory algorithms that measure both intact immunoglobulins and monoclonal FLCs, at diagnosis and when monitoring response to treatment. A particular focus in the field has been on the utility of serum FLC (sFLC) assays to replace urine electrophoresis for monoclonal FLC measurement. Due to the limited sensitivity and practical constraints of urine analysis, a serum-based algorithm of SPE and sFLC has been adopted by many laboratories as a first line screen in patients with suspected monoclonal gammopathies. This review will discuss the data supporting the use of this simple serum-based algorithm at initial diagnosis, including its utility for the rapid identification of monoclonal FLC in the setting of unexplained acute kidney injury, and provide a comprehensive review of the diagnostic sensitivity of sFLC in patients with multiple myeloma, AL amyloidosis and light chain deposition disease.

Abstract
Artemisinin is a drug, widely used in malaria treatment. As the binding affinity of artemisinin and its derivatives dihydroartemisinin and artesunate to blood serum proteins might influence the effectiveness of the drug, binding of artemisinin and derivatives to serum albumin was studied under near physiological conditions. Binding kinetics indicate a simple, single-step association process for all artemisinin derivatives. The determined changes in enthalpy and entropy upon drug binding clearly indicate that hydrophobic forces are most important for artemisinin and dihydroartemisinin binding, whereas binding of artesunate is governed by both hydrophilic and hydrophobic forces. Key residues, which are most likely involved in binding of the respective compounds, were identified in subsequent protein/drug docking studies. The obtained results not only explain differences in between artemisinin and derivatives but generally illustrate how slight modifications in a drug can significantly affect principles underlying drug binding to target proteins.

Abstract
BACKGROUND The present study deals with the effect of helminthic infection as Nematode parasite like Aspiculuris tetraptera on the haematological parameters of infected and vaccinated mice. METHODS Totally 15 mice were used. Five mice were used for positive control, 5 mice used for negative control and 5 mice used for experiment. The hematological parameters were studied viz. RBC, Hb, and serum protein values. RESULTS The mice carrying heavy infection showed decrease in the Hb, RBC, and serum protein but in the vaccinated mice, all studied parameters were become on normal range. The level of immune response was assessed based on above studied hematological parameters in infected and vaccinated mice with Aspiculuris tetraptera. CONCLUSION The increased value of RBC, Hb and Serum protein in infected and vaccinated mice compared to infected and non vaccinated suggested the involvement of blood parameters in immune response. This study also proves that somatic antigen of A. tetraptera was effective in imparting immunity in mice.

Abstract
The study evaluated the damage caused by Haemonchus contortus in terms of blood loss, faecal clearance of plasma protein and elevated serum enzyme activity in Sahabadi sheep. Apparently healthy Sahabadi sheep (n = 15) were selected randomly based on phenotypic characteristics and divided into two groups; infected (n = 8) and uninfected control (n = 6) and one sheep was used as donor animal. Each animal of infected group were orally infected with 700 third stage larvae (L3) of H. contortus/kg body weight. Blood from all the fourteen animals were collected at weekly intervals starting from day one to 42 day post infection. Parameters studied were haemoglobin concentration (Hb), packed cell volume (PCV), total erythrocyte count (TEC), total serum protein, serum albumin, serum globulin, alkaline phosphatase, Alanine amino transferase and Aspartate amino transferase. Statistical analysis showed that significant decreases in Hb, PCV, TEC and serum protein concentration and significant increases in serum enzymes level in infected sheep compared to uninfected control. The present study concluded that experimental H. contortus infection caused disturbances to the haemopoietic system resulting anaemia and severe damage to abomasal mucosa resulting lower serum protein and higher enzyme activities.

Abstract
AIM: To explore the molecular mechanism underlying the development of Yin deficiency of the liver and kidneys in patients with chronic hepatitis B by comparing plasma protein expression between chronic hepatitis B patients with Yin deficiency of the liver and kidneys and normal controls.
METHODS: Plasma proteins from all experimental subjects were separated by two-dimensional gel electrophoresis (2-DE). The proteomic expression profiles were analyzed by comparative proteomic technique to discover differentially expressed protein spots, which were then identified by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS).
RESULTS: Six protein spots which showed at least two-fold differential expression between patients and normal controls were detected, of them Apo AI, Apo AII, haptoglobin, and retinol-binding protein were identified by MALDI-TOF-MS. All the four proteins showed lower expression in chronic hepatitis B patients with Yin deficiency of the liver and kidneys than in normal controls.
CONCLUSION: The proteins identified in this study may be related to the development of Yin deficiency of the liver and kidneys in patients with chronic hepatitis B and represent useful molecular targets for diagnosis and treatment of the syndrome.

Abstract
AIM: To investigate the pathogenesis of cryptogenic hepatitis (CH) by screening its binding protein of serum protein.
METHODS: Using serum protein of cryptogenic hepatitis as the selective molecule, T7 select phage from human liver cDNA library was biopanned and the positive clones were selected 5 times. After polymerase chain reaction of bacteriophage plaque, the DNA fragments of the screened clones were sequenced, and the amino acid sequence of target protein was compared with protein sequence database from BLAST in GenBank.
RESULTS: After bioamplification for 5 times, 24 positive clones were obtained from 60 clones screened randomly. The sequence of the positive clones were researched for homology, and Homo sapiens hepatitis V virus NS5A trans-regulated protein 13 was ascertained as the serum protein of CH-binding protein, which was located at liver.
CONCLUSION: Serum CH protein is interacted with Homo sapiens hepatitis V virus NS5A trans-regulated protein 13 in liver, which plays an important role in the pathogenesis and treatment of CH.

Abstract
BACKGROUND Monoclonal gammopathies occurs in patients with malignant diseases of plasma cells and lymphocytes and in few benign conditions. The objective of this study was to assess the precision, accuracy and confirmation of monoclonal gammopathies on serum protein electrophoresis (SPE) and the clinical relevance of detection and characterization of M component. METHODS All samples received for serum electrophoresis in the last 3 years were analysed for data on M band positivity and correlating it with clinical profile of the patients. Immunofixation (IFE), Immunoelectrophoresis (IEP) and IgG, IgM estimation were carried out in few cases. The follow up of cases was done by serial monitoring of SPE and β2 microglobulin levels. RESULTS 1155 samples were received during the 3 years period. 282 (24.4%) samples were positive for M component on SPE. Of these, 239 (84.8%) patients had M spike in λ region and 43 patients had M spike in β region. The mean load of the M protein band in the λ region was 37.8% and in β region was 35.8%. IgG with κ chain was seen in 40%, IgG with λ chain was seen in 50%, 5% patients each had IgM with κ and IgA with λ light chain. 246 samples (96.5%) had high levels of β2 microglobulin. Of the 116 cases of multiple myeloma, IgG levels was more commonly raised (5%) as compared to IgA (6.9%) and IgM (5.2%). CONCLUSION It is recommended that SPE should be performed in patients having unexplained weakness, anaemia, back pain, osteoporosis, osteolytic lesions, fractures, renal insufficiency or recurrent infections.
