Abstract
BACKGROUND A complete blood count (CBC) analysis is one of the most common conventional blood tests that physicians frequently prescribe. THE OBJECTIVE of this study was to determine the reference intervals (RIs) of CBC parameters in the population of healthy adults living in the western Sudan region. METHODS A cross-sectional study of healthy people residing in the western area of Sudan was carried out. We assessed the CBC RIs in samples taken from 153 individuals using an automated haematology analyser (Sysmex KX-21) and a modified Box-Cox transformation procedure to transform the data into a Gaussian distribution after eliminating outliers using the Dixon method. IBM SPSS Statistics version 25 was used to analyse the data, and t tests were employed to examine variations in the mean CBC parameters according to sex and age. P was considered significant at ≤ 0.05. RESULTS Beyond all the other measured values, the only CBC parameters that significantly differed between the sexes were haemoglobin (HGB) and white blood cell (WBC) counts. Women were found to experience more WBC counts than men did. However, they have less HGB RIs.The male participants in our study exhibited lower WBC count RIs, a significantly lower limit, and a greater upper limit of platelet RIs than did the individuals from other nations. CONCLUSIONS Compared with males, females had higher platelet and WBC counts and lower HGB.

Abstract
The purpose of this study was to develop an effective and non-invasive nomogram for evaluating liver obvious inflammation in untreated HBeAg positive patients with chronic hepatitis B virus (HBV) infection. A nomogram was established on a model cohort of 292 treatment-naïve HBeAg positive patients with normal alanine aminotransferase (ALT ≤40 U/L) at Beijing Ditan Hospital from January 2008 to March 2018. Then the nomogram was prospectively validated in a cohort of 88 patients from July 2019 to May 2021. Calibration curves and Concordance index were used to evaluate the accuracy of prediction and identification performance of the model. In untreated HBeAg positive chronic hepatitis B virus infection patients with normal ALT, the formula for predicting liver inflammation was Logit (P) =-0.91-0.41×log10 (qHBeAg)+0.11×AST-0.01×PLT. The nomogram had C-index of 0.751 (95% CI, 0.688-0.815), indicating a good consistency between prediction and real observation on the model cohort. The validation cohort confirmed its good performance. In this study, liver inflammation nomograms based on HBeAg, AST, and PLT were established and verified in treatment-naïve HBeAg positive chronic HBV patients with normal ALT.

Abstract
The evolution of roots allowed vascular plants to adapt to land environments. Fossil evidence indicates that roots evolved independently in euphyllophytes (ferns and seed plants) and lycophytes, the two lineages of extant vascular plants. Based on a high-quality genome assembly, mRNA sequencing (mRNA-seq) data, and single-cell RNA-seq data for the lycophyte Selaginella kraussiana, we show that the two root origin events in lycophytes and euphyllophytes adopted partially similar molecular modules in the regulation of root apical meristem (RAM) development. In S. kraussiana, the RAM initiates from the rhizophore primordium guided by auxin and duplicates itself by dichotomous branching. The auxin signaling pathway directly upregulates euAINTEGUMENTAb (SkeuANTb), and then SkeuANTb directly promotes the expression of SkeuANTa and the WUSCHEL-RELATED HOMEOBOX13b (SkWOX13b) for RAM maintenance, partially similar to the molecular pathway involving the euANT-branch PLETHORA (AtPLT) genes and AtWOX5 in root initiation in the seed plant Arabidopsis thaliana. Other molecular modules, e.g., SHORT-ROOT and SCARECROW, also have partially similar expression patterns in the RAMs of S. kraussiana and A. thaliana. Overall, our study not only provides genome and transcriptome tools of S. kraussiana but also indicates the employment of some common molecular modules in RAMs during root origins in lycophytes and euphyllophytes.

Abstract
Polycystic ovarian syndrome (PCOS) is characterized by the abnormal production of ovarian androgens resulting in elevated levels of male sex hormones in women. This condition is often marked by the development of a group of small cysts, fluid-filled sacs (cysts) in the ovaries. This study aimed to analyze serum levels of prolactin, follicle-stimulating hormone (FSH), luteinizing hormone (LH), and specific hematological parameters in women with PCOS. In total, 70 women were enrolled, of which 50 were diagnosed with PCOS at an obstetrics institution in Karbala from February and May 2022, and 20 were excluded. Participant selection was based on the Rotterdam 2003 criteria, and we excluded postmenopausal women, those with hyperprolactinemia, and those with overt thyroid dysfunction. The control group included 20 fertile women with normal hormone levels, regular menstrual cycles, and no signs of hyperandrogenism, as verified by ultrasonography. Ages 15 to 46 were similar with regard to the frequency of illness, with those under 36 having a higher incidence. Data were collected via questionnaires, hormone level assessments, and complete blood count (CBC) tests. There was a significant increase in hormone levels (LH, FSH, prolactin, TSH) and CBC values (WBC, Hb, and Plt) in the PCOS group compared to the control group. We observed that women between 26 and 35 were more susceptible to PCOS. Furthermore, women who were overweight demonstrated a higher susceptibility to the syndrome.

Abstract
During the COVID-19 pandemic, different SARS-CoV-2 variants of concern (VOC) with specific characteristics have emerged and spread worldwide. At the same time, clinicians routinely evaluate the results of certain blood tests upon patient admission as well as during hospitalization to assess disease severity and the overall patient status. In the present study, we searched for significant cell blood count and biomarker differences among patients affected with the Alpha, Delta and Omicron VOCs at admission. Data from 330 patients were retrieved regarding age, gender, VOC, cell blood count results (WBC, Neut%, Lymph%, Ig%, PLT), common biomarkers (D-dimers, urea, creatinine, SGOT, SGPT, CRP, IL-6, suPAR), ICU admission and death. Statistical analyses were performed using ANOVA, the Kruskal-Wallis test, two-way ANOVA, Chi-square, T-test, the Mann-Whitney test and logistic regression was performed where appropriate using SPSS v.28 and STATA 14. Age and VOC were significantly associated with hospitalization, whereas significant differences among VOC groups were found for WBC, PLT, Neut%, IL-6, creatinine, CRP, D-dimers and suPAR. Our analyses showed that throughout the current pandemic, not only the SARS-CoV-2 VOCs but also the laboratory parameters that are used to evaluate the patient's status at admission are subject to changes.

Abstract
BACKGROUND AND OBJECTIVES The platelet (PLT) value in hepatitis B-related acute-on-chronic liver failure (HBV-ACLF) is not sufficiently understood. The present study aimed to evaluate the prognostic effect of PLT on the prediction of HBV-ACLF outcomes after plasma exchange (PE). METHODS HBV-ACLF patients treated with PE between January 2017 and August 2021 were followed up for at least 6 months. Cox regression was performed to develop the predictive model, and the model's performance was analyzed using the receiver operating characteristic curve (ROC). RESULTS A total of 170 patients were included. The overall survival rate within 180 days was 75.88%. Age, PLT, total bilirubin (TBil), and the iMELD scores were independent risk factors affecting the prognosis of HBV-ACLF patients after PE. According to the Cox regression results, the new model was calculated: R = 0.142 × iMELD-0.009 × PLT. The area under the curve (AUC) of the receiver operating characteristic curve (ROC) was 0.758 (95% CI 0.678-0.838), and patients with lower PLT-iMELD scores (<4.50) had a better prognosis (p < 0.001). CONCLUSION PLT is a valuable prognostic biomarker for HBV-ACLF patients after PE. The modified iMELD model incorporating PLT has a better sensitivity and efficacy in predicting the prognosis of patients.

Abstract
Deriving the detailed synaptic connections of an entire nervous system is the unrealized goal of the nascent field of connectomics. For the fruit fly Drosophila, in particular, we need to dissect the brain, connectives, and ventral nerve cord as a single continuous unit, fix and stain it, and undertake automated segmentation of neuron membranes. To achieve this, we designed a protocol using progressive lowering of temperature dehydration (PLT), a technique routinely used to preserve cellular structure and antigenicity. We combined PLT with low temperature en bloc staining (LTS) and recover fixed neurons as round profiles with darkly stained synapses, suitable for machine segmentation and automatic synapse detection. Here we report three different PLT-LTS methods designed to meet the requirements for FIB-SEM imaging of the Drosophila brain. These requirements include: good preservation of ultrastructural detail, high level of en bloc staining, artifact-free microdissection, and smooth hot-knife cutting to reduce the brain to dimensions suited to FIB-SEM. In addition to PLT-LTS, we designed a jig to microdissect and pre-fix the fly's delicate brain and central nervous system. Collectively these methods optimize morphological preservation, allow us to image the brain usually at 8 nm per voxel, and simultaneously speed the formerly slow rate of FIB-SEM imaging.

Abstract
The research into and production of hematological reference samples used to implement an external quality assessment (EQA) to check the quality of hematology tests are necessary for hematology laboratories in Vietnam. In this research, the study team determined the assessment values of blood cell count (human RBCs, pseudo-leucocytes, and pseudo-platelets) by the impedance method used in hematology EQA programs. The hematological reference samples were controlled at three concentration levels: low, normal, and high. Determination of the assigned value (mean ± 2SD) was performed for the following hematology analyzer series by impedance method: ABX Micros 60, Celldyn 1700, and Mindray BC 2000. Each device was sent to 10 different laboratories for evaluation. Research results for assigned values of each model (ABX Micros 60, Celldyn 1700, and Mindray BC 2000) were determined at the three concentrations. For the ABX Micros 60 and Celldyn 1700 series, 80% of laboratories had analytical results within assigned values. For the Mindray BC 2000 series, 100% of laboratories had analytical results within assigned values. The measurement results for the number of human RBCs, pseudo-leucocytes, and pseudo-platelets on each analyzer were similar between the 10 laboratories; the results of the three hematology analyzer series using the impedance method were different and the difference was statistically significant (p < 0.05). Thus, hematological reference samples for measuring the number of blood cells meeting the standards so that they can evaluate the results of laboratories using the impedance method: ABX, Celldyn 1700, Mindray BC 2000.

However, the role of DYSF in the pathogenesis of atherosclerotic cardiovascular diseases (ASCVD) and the regulation mechanism of DYSF expression have not been fully studied. In this study, Gene Expression Omnibus (GEO) database and epigenome-wide association study (EWAS) literatures were searched to find the DNA methylation-driven genes (including DYSF) of ASCVD. The hub genes related to DYSF were also identified through weighted correlation network analysis (WGCNA). Regulation of DYSF expression through its promoter methylation status was verified using peripheral blood leucocytes (PBLs) from ASCVD patients and normal controls, and experiments on THP1 cells and Apoe-/- mice. Similarly, the expressions of DYSF related hub genes, mainly contained SELL, STAT3 and TMX1, were also validated. DYSF functions were then evaluated by phagocytosis, transwell and adhesion assays in DYSF knock-down and overexpressed THP1 cells. The results showed that DYSF promoter hypermethylation up-regulated its expression in clinical samples, THP1 cells and Apoe-/- mice, confirming DYSF as a DNA methylation-driven gene. The combination of DYSF expression and methylation status in PBLs had a considerable prediction value for ASCVD. Besides, DYSF could enhance the phagocytosis, migration and adhesion ability of THP1 cells. Among DYSF related hub genes, SELL was proven to be the downstream target of DYSF by wet experiments. In conclusion, DYSF promoter hypermethylation upregulated its expression and promoted monocytes activation, which further participated in the pathogenesis of ASCVD.

Abstract
AIM Accurate detection of the hepatic fibrosis stage is essential to estimate the outcome of patients with non-alcoholic fatty liver disease (NAFLD). Many formulas, biomarkers, and imaging tests are being developed to predict advanced liver fibrosis without performing a liver biopsy. However, these tests do not have high efficiency in detecting early-stage hepatic fibrosis. Therefore, we aimed to detect the presence of hepatic fibrosis (≥F1) merely by using only standard clinical markers. METHODS A total of 436 patients with NAFLD who underwent liver biopsy were retrospectively enrolled as the discovery cohort (316 patients) and the validation cohort (120 patients). Liver biopsy and laboratory data were matched to extract simple parameters for identifying ≥F1. RESULTS We developed a novel simplified ≥F1 detecting system, designated as 2-Step PLT16-AST44 method, where (1) PLT of 16 × 104 /μl or less, or (2) PLT greater than 16 × 104 /μl and AST greater than 44 U/L is determined as having ≥F1 fibrosis. The 2-Step PLT16-AST44 method had a sensitivity of 68%, a specificity of 90%, a positive predictive value (PPV) of 97%, a negative predictive value (NPV) of 40%, and an accuracy of 72% to detect ≥F1 fibrosis in the discovery cohort. Validation studies further supported these results. Despite its simplicity, the 2-Step PLT16-AST44 method's power to detect ≥F1 fibrosis in total NAFLD patients was comparable to hyaluronic acid, type 4 collagen 7S, FIB-4, and APRI. CONCLUSIONS We propose the 2-Step PLT16-AST44 method as a simple and beneficial early-stage hepatic fibrosis detection system.

Abstract
Background: Apatinib has a certain efficacy for advanced esophageal squamous cell carcinoma (ESCC). This study aimed to investigate the prognostic significance of platelet (PLT) and platelet to mean platelet volume (PLT/MPV) ratio for advanced ESCC patients with apatinib second-line or late-line treatment. Methods: A retrospective study included 80 patients with advanced ESCC who received Apatinib ≥ 2 lines targeted therapy. We collected baseline clinical characteristics and blood parameters from the patients. Kaplan-Meier plots and univariate and multivariate analysis were used to find the factors related to progression-free survival (PFS). Results: The optimal cut-off values of PLT and PLT/MPV ratio were determined by X-tile software. Kaplan-Meier analysis demonstrated that patients in the high PLT group had better PFS than those in the low PLT group (156 d vs 80 d, P <.001), and patients in the high PLT/MPV ratio group had better PFS than those in low PLT/MPV ratio group (157 d vs 85 d, P <.001). Univariate analysis revealed pretreatment PLT and PLT/MPV ratio were significantly correlated with PFS. Multivariate analysis revealed high levels of pretreatment PLT/MPV ratio was an independent predictor of longer PFS (HR: 0.257, 95% CI: 0.089-0.743, P = .012). Conclusion: High levels of baseline PLT and PLT/MPV may indicate a better prognosis in apatinib ≥ 2 lines treatment for advanced ESCC patients.

Abstract
Platelets are associated with the processes that aid in tumour growth and progression. Platelet Count (PLT) and platelet indices like Mean Platelet Volume (MPV), Platelet Large Cell Ratio (P-LCR), Plateletcrit (PCT) and Platelet Distribution Width (PDW) are markers that are linked with platelet activities in cancer. This review involves the evaluation of PLT, MPV and PCT in different cancers. Platelets actions should be always monitored during several diseases, as their potential exceeds the classical function in preventing bleeding. Vast roles of platelets were discovered in several biological functions. Therefore, studying their indices can be effective in the diagnosis of several disorders including cancer.

Abstract
Quantitative estimation of mechanical characteristics of soils and determination of their behavior using in-situ experiments have always been one of the main concerns of geotechnical engineers. So far, various methods have been introduced to achieve this goal, among which the Dynamic Cone Penetrometer (DCP) test has become more popular as one of the most accurate and efficient methods. Therefore, in this study, an attempt was made to examine the correlation between different soil parameters by performing DCP test along with a series of conventional tests including Unconfined Compressive Strength (UCS) and California Bearing Ratio (CBR) tests on marl soil samples containing 2, 5, 8% lime at 1, 7 and 15 curing days. Furthermore, since the subgrade reaction coefficient (Ks) is needed in the design of pavements and their underlying materials, Plate Load Test (PLT) was performed to determine Ks. The results showed that the addition of lime up to 5% increased UCS, CBR and Ks and decreased dynamic penetrometer index (DPI) of marl soil samples. Further addition of lime had a negative effect on the mechanical characteristics of the samples. Moreover, using the equations obtained from the correlations in this study, strength characteristics and subgrade reaction coefficient of the stabilized marl soil can be estimated by knowing the DPI of the samples. The results of this study showed that the use of the DCP test as a cheap and easy-to-use method can provide a comprehensive view of soil behavior in civil engineering projects with an acceptable coefficient of determination to geotechnical engineers.

Abstract
Objective There are several clinical cases on the application of PRP (platelet-rich plasma) therapies. To improve disadvantages such as the inability to be standardized and stored long term, we proposed a novel platelet-lyophilized treatment (PLT) to enhance the wound healing rate and improve acne scarring. Study Design A single-blinded study at a single health care center was performed. All subjects were treated with a fractional carbon dioxide laser. On the right side of the face, 2 mL PLT solution (dissolved in normal saline) was applied, while on the left side of the face (control group), 2 mL normal saline was applied. The treatment described above was repeated every 3 to 4 weeks, and 4 treatments were performed in total. Assessments were performed prior to each treatment and at the one-month follow-up after the fourth treatment. Subjective assessments included questionnaires administered by the principal investigator and a self-assessment questionnaire completed by the subjects. Moreover, VISIA complexion analysis was used for objective data collection, and spots, wrinkles, texture, pores, UV spots, brown spots, red areas, and porphyrins were objectively analyzed. Results Our data indicated that the PLT side showed a more rapid recovery than the saline side; on average, the sloughing off of the crusts was noted on day 5 and day 6. The improvement rate for skin spots, texture, and pores was significantly increased on the PLT side, with the pigment and pore size both having a statistically significant improvement of p<0.001, while the texture had a significant improvement of p<0.01. Conclusion The results suggested that the application of PLT could be a novel method to enhance wound healing and improve acne scarring after laser skin rejuvenation.

Abstract
Objective: To evaluate the value of combined interferon β (IFN-β) and platelet (PLT) detection for Kawasaki disease (KD) identification. Methods: Forty-four children who were newly diagnosed with KD were selected as the KD group. They were divided into acute phase of KD and subacute phase of KD. They were also separated into groups with and without coronary artery disease (CAD) (CAD+ and CAD-, respectively). Meanwhile, 44 children hospitalized with febrile disease and 44 healthy children were selected as a febrile control group and normal control group, whom were attended to at Children's Hospital of Soochow University at the same time. We detected the concentration of IFN-β and PLT of peripheral blood serum for all three groups and analyzed the difference. Results: At acute and subacute phases of KD, both IFN-β and PLT are higher than both the febrile control group and healthy control group, especially at subacute phase; the difference between groups was statistically significant, P < 0.05. Receiver operating characteristic (ROC) curve showed that the areas under the ROC curve (AUCs) of IFN-β and PLT at acute phase of KD were 0.81 and 0.72, respectively; the sensitivity and specificity were 97.22 and 63.64%, and 57.89 and 73.86%, respectively. The AUCs of combined IFN-β and PLT were 0.81 at acute phase and 0.96 at subacute phase of KD, with sensitivity and specificity of 97.22 and 55.26%, and 86.36 and 100%, respectively. The cutoff value of combined IFN-β and PLT detection was IFN-β = 3.51 pg/ml and PLT = 303 × 109/L at acute phase of KD, IFN-β = 4.21 pg/ml and PLT = 368 × 109/L at subacute phase from plot vs. criterion values. However, there are no significant differences between the CAD- group and the CAD+ group for combined IFN-β and PLT, both P > 0.5, neither at acute nor at subacute phase of KD. Conclusion: Combined IFN-β and PLT detection is an efficient biomarker for KD identification. The cutoff values are IFN-β = 3.51 pg/ml and PLT = 303 × 109/L at acute phase of KD and IFN-β = 4.21 pg/ml and PLT = 368 × 109/L at subacute phase.

Abstract
PURPOSE 99mTc-HMPAO radiolabeled autologous leukocyte scintigraphy is routinely used clinically for infection imaging. Leukocytes are mostly separated via sedimentation. It is unknown whether leukocytes are clearly separated by sedimentation or selectively labeled. Therefore, in this study, the blood cell numbers were investigated after leukocyte radiolabeling to identify the cells strongly radiolabeled by 99mTc-HMPAO. METHODS This study was performed with leftover blood samples of the patients who underwent 99mTc-HMPAO scintigraphy at Chonbuk National University Hospital (2018-2019). The blood of 22 patients was drawn for 99mTc-HMPAO scintigraphy. WBCs were separated via conventional sedimentation at our clinic and radiolabeled. The concentration of cell components was determined using an automatic hematology analyzer. The cells in the final sample injectate sample were separated using Histopaque and counted with a dose calibrator. RESULTS The average numbers of RBCs, WBCs, and PLTs in the final injection sample were 79 ± 33, 23.26 ± 11.95, and 229.5 ± 206.57 x 103/μL, respectively. The PLT number was almost 10-fold the number of WBCs. The number of RBCs was nearly 3-fold higher than WBCs [RBC/WBC ratio = 4.67 ± 3.58, and PLT/WBC ratio = 10.65 ± 12.46]. Following Histopaque separation, the activity of each layer showed 99mTc-HMPAO labeling of WBC > RBC > PLT in order. The total activity/cell numbers of WBCs, RBCs and PLTs were 0.016 ± 0.010, 0.005 ± 0.005 and 0.003 ± 0.002, respectively (p > 0.05). CONCLUSION Although the numbers of RBCs and PLTs were highly increased after sedimentation, their individual cellular activity was lower than that of WBCs. 99mTc-HMPAO was more selective to WBCs than RBCs or PLTs. In conclusion, a higher number of WBCs were radiolabeled compared with RBCs and PLTs.

Abstract
Aerial organs of plants, being highly prone to local injuries, require tissue restoration to ensure their survival. However, knowledge of the underlying mechanism is sparse. In this study, we mimicked natural injuries in growing leaves and stems to study the reunion between mechanically disconnected tissues. We show that PLETHORA (PLT) and AINTEGUMENTA (ANT) genes, which encode stem cell-promoting factors, are activated and contribute to vascular regeneration in response to these injuries. PLT proteins bind to and activate the CUC2 promoter. PLT proteins and CUC2 regulate the transcription of the local auxin biosynthesis gene YUC4 in a coherent feed-forward loop, and this process is necessary to drive vascular regeneration. In the absence of this PLT-mediated regeneration response, leaf ground tissue cells can neither acquire the early vascular identity marker ATHB8, nor properly polarise auxin transporters to specify new venation paths. The PLT-CUC2 module is required for vascular regeneration, but is dispensable for midvein formation in leaves. We reveal the mechanisms of vascular regeneration in plants and distinguish between the wound-repair ability of the tissue and its formation during normal development.

Abstract
The sol-gel method was used to prepare perovskite type (Pb1-1.5x Lax□0.5x)TiO3 (PLT) ceramics with x = 0.21, 0.22, 0.23, 0.24, 0.25 in order to investigate their structural, optical, and dielectric properties. The crystallite compounds were obtained by calcinating the mixture of PbCO3, TiO2, and La2O3 at 1000 °C for different time periods. After 4 h annealing, PLT23 sample, approximately a very little secondary phases have been observed in the XRD spectrum of the PLT sample with 23% La content (PLT23). The presence of La dopants might have affected the tetragonality of the Lead titanate crystal structure. The PLT samples tolerance factor decreases from 0.991 as in x = 0.21 to 0.986 for x = 0.25. Hence, these structures tend, generally, to be in the perovskite phase as t ~ 1. In the doped ceramics, characteristic phase transitions were shifted to lower temperatures. The dielectric permittivity value showed the tendency of a slight increase with lanthanum addition and achieved its maximum εm (3649) at x = 0.23, then it decreases for higher concentrations of La. The samples' estimated average crystallite size ranged from 40 nm to 50 nm, the maximum crystallite size about (49.6 nm) at x = 0.23 La. The calculated bandgaps were 3.1, 3.26, 3.28, 3.08, and 3.12 for the PLT with 0.21, 0.22, 0.23,0.24 and 0.25% La, respectively. The Curie constant C was obtained as the slope of the curve of the inverse values of εr vs. temperature. The highest C value (5.2 × 105 K) was measured for the 23% La sample. The sample with 23% La content appears to be notably distinguished in its structural, optical, and dielectric characteristics compared with other samples.

Abstract
Background: Lung cancer is the leading cause of cancer death. Platelet-related indictors, including platelet count, plateletcrit, mean platelet volume, and platelet distribution width, not only associate with morphology and functions of platelet but also correlate with tumor development and metastasis. In the present study, we investigated the values of platelet-related indictors in the prognosis evaluation of resectable lung cancers. Methods: In total, 101 patients with resectable lung cancer were recruited in this study. Patients were divided into 2 groups according to the median pretreatment values. To evaluate the individual value changes after treatment, we introduced the concept of post-/pretreatment ratio (≤1 indicated value was not increased after treatment, while >1 suggested increased value). Results: The high pretreatment platelet count level was correlated with larger tumor size. High pretreatment plateletcrit level was associated with more lymph nodes metastasis. Patients with high pretreatment plateletcrit level had worse overall survival, whereas pretreatment platelet count, mean platelet volume, and platelet distribution width levels were not correlated with outcomes. Surgery had no impact on the values of platelet count, plateletcrit, mean platelet volume, or platelet distribution width. Adjuvant chemotherapy significantly decreased the values of platelet count and plateletcrit, whereas it had no effect on the values of mean platelet volume or platelet distribution width. Whole course of treatment (surgery combined with adjuvant chemotherapy) significantly decreased the values of platelet count and platelet distribution width, whereas it had no effect on the values of plateletcrit or mean platelet volume. Post-/pretreatment platelet count, plateletcrit, mean platelet volume, and platelet distribution width ratios were not correlated with outcomes. Univariate analyses demonstrated that American Joint Committee on Cancer stage and pretreatment plateletcrit level were significant risk factors for prognosis. Cox regression analysis revealed that no factor independently associated with worse survival. Conclusion: Pretreatment plateletcrit level could be a potential prognostic factor in resectable lung cancers.

Abstract
AIMS The red blood cell distribution width-to-platelet ratio (RPR) has been reported to be an indicator of hepatic fibrosis in patients with chronic hepatitis B (HBV), nonalcoholic fatty liver disease (NAFLD) or chronic hepatitis C (HCV). However, no research has explored the RPR in all patients with hepatic fibrosis. There is a recognized need to establish whether the RPR could assess hepatic fibrosis and reflect the severity of fibrosis, regardless of the patient's etiology. METHODS Quantitative data from 1282 patients who underwent liver biopsy between January 2010 and December 2014 at the Second Affiliated Hospital of Zhejiang University School of Medicine were included. The etiologies included HBV or HCV infection, NAFLD, schistosomiasis, granulomatous liver disease, and vascular abnormalities. Five noninvasive models were calculated for all patients based on laboratory parameters. The degrees of fibrosis severity were evaluated based on the Metavir scoring scale. RESULTS The RPR demonstrated the best accuracy of predicting hepatic fibrosis among the selected five models (0.75, p < .001) regardless of etiology. In addition, the RPR values increased with advanced hepatic fibrosis progression. Furthermore, combining the RPR with the white blood cell (WBC) count improved the accuracy of grading hepatic fibrosis as reflected by the likelihood ratio (LR + 9.03, LR - 0.49). CONCLUSION The RPR is a useful indicator for hepatic fibrosis, regardless of etiology, and can reflect the severity of fibrosis. This study supports further clinical development of the RPR both in a stepwise manner or in combination with inflammatory parameters to improve the accuracy of scoring hepatic fibrosis.

Abstract
BACKGROUND AND AIM Hepatitis C virus infection is associated with thrombocytopenia. Thrombocytopenia recovers after viral eradication. The current study explored the rate and factors associated with platelet (PLT) recovery, which may represent the degree of liver fibrosis regression. METHODS A total of 466 patients who achieved a sustained virological response were enrolled to compare the PLT change after a mean follow-up period of 85.5 months (range 12-163 months). RESULTS Platelet counts increased significantly after achieving sustained virological response (from 166 ± 55 × 103 to 201 ± 61 × 103 u/L, P < 0.001). The median PLT count increment was 5.03 × 103 u/L per year. Logistic regression analysis revealed that factors associated with slow PLT count recovery were high pretreatment PLT counts (odds ratio [OR]/ 95% confidence intervals [CI]: 0.992/0.989-0.996, P < 0.001) and hepatitis B virus (HBV) co-infection (OR/CI: 0.416/0.220-0.785, P = 0.007). High PLT counts were the only factor associated with slow PLT recovery in patients with mild liver disease (F0-2) (OR/CI: 0.992/0.987-0.996, P < 0.001). On the other hand, HBV co-infection was the only factor associated with slow PLT recovery in patients with advanced fibrosis (OR/CI: 0.207/0.054-0.789, P = 0.02). Linear regression analysis of factors correlated to the delta PLT count change per year in patients with F0-2 included pretreatment white blood cell (β: -0.001; CI: -0.002-0.000; P = 0.01) and pretreatment PLT counts (β: -0.037; CI: -0.061 to -0.013; P = 0.003). HBsAg seropositivity was the only factor correlated to the delta PLT count change per year (β: -10.193; CI: -16.752-3.635; P = 0.003) among patients with F3-4. CONCLUSIONS Platelet counts recovered after hepatitis C virus eradication. HBV dual infection disrupted PLT count recovery, especially in CHC patients with advanced liver disease.

Abstract
The aim of this study is to underline the necessity of a better knowledge of pedicles anatomy in order to improve surgical treatment of spine disorders such us low back pain, spinal fractures and scholiosis. A classification of pedicles lateral tilt which could help surgeons before the application of screws during transpedicular fixation is reported. Anatomical differences in the orientiation of the pedicles of L5 and L4 have been found. For each patient that met the inclusion criteria underwent: Radiography of the lumbo-sacral region, CT examination, MRI acquisition. Patients were divided into three categories thanks to 3D direct volume rendering of CT scan. Subjects belonged to W-Type, V-Type and U-type depending on their morphometric features. The subdivision was further implemented with measurements of the distance between pedicles and adjacent nervous structures. Concerning L5, W-Type (WT) exhibited a lateral tilt of L5 larger than 36°, V-Type exhibited a lateral tilt of L5 from 30° to 36°, U-type exhibited a lateral tilt of L5 smaller than 30°. Concerning L4, WT exhibited a lateral tilt of 28.4°, VT exhibited a lateral tilt of of 25.1, UT exhibited a lateral tilt of 22.2°; we assume that the degree of lateralization of L4 depends on the one of L5. The way the screw is applied during surgical treatment is clinically relevant, thus our classification may be very useful in order to decrease surgical risk and improve conditions of patients after surgical treatment.

Abstract
The last decade has witnessed an explosion in the depth, variety, and amount of human genetic data that can be generated. This revolution in technical and analytical capacities has enabled the genetic investigation of human traits and disease in thousands to now millions of participants. Investigators have taken advantage of these advancements to gain insight into platelet biology and the platelet's role in human disease. To do so, large human genetics studies have examined the association of genetic variation with two quantitative traits measured in many population and patient based cohorts: platelet count (PLT) and mean platelet volume (MPV). This article will review the many human genetic strategies-ranging from genome-wide association study (GWAS), Exomechip, whole exome sequencing (WES), to whole genome sequencing (WGS)-employed to identify genes and variants that contribute to platelet traits. Additionally, we will discuss how these investigations have examined and interpreted the functional implications of these newly identified genetic factors and whether they also impart risk to human disease. The depth and size of genetic, phenotypic, and other -omic data are primed to continue their growth in the coming years and provide unprecedented opportunities to gain critical insights into platelet biology and how platelets contribute to disease.

Abstract
PURPOSE Locking compression plates (LCP) allow trauma and orthopedic surgeons to have a variety of options for utilizing locking and non-locking screw features. In this study, the hybrid constructs of mixed unicortical and bicortical screws were investigated for humerus midshaft fractures. The locking and non-locking features were also incorporated into the hybrid LCP constructs. Kryptonite™ bone cement is biocompatible with low exothermic properties and strong metal adhesion. This novel bone cement was incorporated into the non-locking screw feature to compare its mechanical effect with that of a traditional locking screw feature. METHODS A total of 24 synthetic bones (Sawbones(®) Inc., USA) were equally divided into three groups (n = 8). The control group obtained traditional LCP fixation (JSM Medimax Inc., India) with bicortical screws, while the hybrid locking constructs employed a mix of bicortical and unicortical screws. The two bicortical screws in hybrid constructs were placed at the end holes of the LCP constructs and the unicortical screws were placed into the remaining holes. The hybrid locking (HL) group contained locking unicortical screws, whereas the hybrid non-locking group (HNK) utilized non-locking screw features incorporating the Kryptonite™ bone cement in the plate/screw bone construct. Specimens were tested by dynamic and static analysis. The eight total constructs were equally divided into two subgroups (n = 4) to conduct axial compression and torsion test individually. The low cyclic test was conducted for dynamic analysis, which included 10,000 cycles at 1 Hz frequency with a cyclic loading of 0-500 N of axial force for the axial compression test and 0-20° of angular displacement for the torsion test. The static analysis was run by a failure test with a nondestructive strain rate of 0.1 mm/s for the axial compression test and 0.5° s(-1) for the torsional test. The construct stiffness of axial compression and torsion were derived from the linear portion of the load-displacement curves. The yield strength of axial compression and torsion was determined by using offset methods. The results of stiffness and yield strength were compared by using both one-way ANOVA and Scheffe and Games-Howell post hoc tests to analyze statically significant differences among the three groups. RESULTS Specimens completed 10,000 cycles in the dynamic analysis of axial and torsional cyclic tests without major deformation. To compare with the control group in static analysis, the HL and HNK groups achieved positive effect in axial stiffness, 12.3% and 10.5% greater than the control group respectively. HL obtained axial yield strength about 12% less than the control group. The HNK group was equivalent with the control group in axial yield strength. The torsional stiffness and yield strength were found similar in three groups, which indicated torsional equivalence among them. The stiffness and yield strength from axial compression and torsion were found statically non-significant among three groups. CONCLUSIONS Hybrid LCP constructs were initially showed to maintain equivalent axial and torsional stability with the traditional method. Kryptonite™ hosted mechanical and biological advantages for internal plate/screws (PLT) fixation.

Abstract
There are no studies comparing platelet parameters platelet parameters (platelet count (PLT), mean platelet volume (MPV) and platelet large cell ratio (P-LCR)) between patients with schizophrenia, bipolar disorder and unipolar depression. Therefore, the aim of this study was to determine and compare differences in PLT, MPV and P-LCR in patients with schizophrenia, unipolar depression and bipolar disorder. This was a retrospective, cross-sectional, naturalistic study of 2377 patients (schizophrenia n=1243; unipolar depression n=791; bipolar disorder n=343, including bipolar depression n=259 and mania n=84). There were significant differences for PLT, MPV and P-LCR values between study groups. A significant percentage of patients with bipolar disorder had abnormal (too low or too high) number of platelets. Negative correlation between PLT and age was found in all study groups and positive correlation between age and MPV and P-LCR was found in patients with schizophrenia.

Abstract
The stem cell niche in the root meristem maintains pluripotent stem cells to ensure a constant supply of cells for root growth. Despite extensive progress, the molecular mechanisms through which root stem cell fates and stem cell niche activity are determined remain largely unknown. In Arabidopsis thaliana, the Pleiotropic Regulatory Locus 1 (PRL1) encodes a WD40-repeat protein subunit of the spliceosome-activating Nineteen Complex (NTC) that plays a role in multiple stress, hormone and developmental signaling pathways. Here, we show that PRL1 is involved in the control of root meristem size and root stem cell niche activity. PRL1 is strongly expressed in the root meristem and its loss of function mutation results in disorganization of the quiescent center (QC), premature stem cell differentiation, aberrant cell division, and reduced root meristem size. Our genetic studies indicate that PRL1 is required for confined expression of the homeodomain transcription factor WOX5 in the QC and acts upstream of the transcription factor PLETHORA (PLT) in modulating stem cell niche activity and root meristem size. These findings define a role for PRL1 as an important determinant of PLT signaling that modulates maintenance of the stem cell niche and root meristem size.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Kalanchoe intergra (Ki) leaf extract is an orally administered multipurpose plant medicine in Ghana and other parts of the world for the treatment of ulcers, pain and adenoma of the prostate gland. There is paucity of information concerning its short-term usage. The present study is aimed at conducting histopathological and biochemical studies in a 14-day sub-acute toxicity studies using female Sprague-Dawley rats. MATERIALS AND METHODS Crude extract of Ki leaves was prepared and freeze-dried. A 14-day sub-acute toxicity studies was conducted using 2 week old nulliparous and non-pregnant female Sprague-Dawley rats (120-150g). Reconstituted Ki was administered at a dosage of 900mgkg(-1) (high dose), 300mgkg(-1) with a control group receiving an equivalent volume of distilled water (as vehicle) by gastric lavage. Histopathological studies of major organs and blood chemistry analysis were performed on blood obtained via cardiac puncture into EDTA tubes after euthanisation. RESULTS There was a significant decrease in urea (p<0.016) and creatinine levels (p<0.001) in both the high and low dose groups. There was an increase in ALP levels (P=0.01) in both the high and low dose groups. ALT and AST rather decreased significantly in both the high and low dose groups (p<0.0001). Histopathological results did not show any abnormalities in all the H&E stained paraffin sections. Thus the photomicrographs of the liver, kidney and heart were within histopathological limits. CONCLUSION Ki leaf extract is non-toxic when administered by the oral route over a time period of 14 days at the above doses.

Abstract
BACKGROUND Liver disease is more severe in patients with chronic hepatitis B virus (HBV) infections and alcohol-induced liver injury. Whether the same is true for alcoholic patients with cirrhosis who have recovered from previous HBV infections remains to be determined. OBJECTIVES To document the extent of liver disease in alcoholic patients with cirrhosis who test negative for hepatitis B surface antigen (HBsAg) and test positive for antibody to hepatitis B core antigen (anti-HBc). METHODS Two hundred fifty-four alcoholic patients with cirrhosis were divided into anti-HBc-positive (N = 171) and anti-HBc-negative (N = 83) cohorts. Demographic, clinical, and biochemical features were retrospectively analyzed. Prognostic scores and the prevalence of patients at high risk for short-term mortality were calculated. Logistic regression was used to identify factors associated with an increased risk for short-term mortality. RESULTS Jaundice was more common in the anti-HBc-positive cohort (32.2% vs. 18.1%, p = 0.02). This cohort also had higher serum bilirubin (70.9 vs. 50.4 μM/L, p = 0.03), prothrombin times (15.6 vs. 14.4 s, p = 0.01), MELD scores (8.5 vs. 4.6, p = 0.01), i-MELD scores (28.6 vs. 24.7, p = 0.03), MDF scores (14.2 vs. 6.8, p = 0.02) and ABIC scores (7.2 vs. 6.6, p = 0.01). In addition, anti-HBC-positive patients were more often at high risk for short-term mortality (40.4% vs. 26.5%, p = 0.03). Multivariate analysis identified anti-HBc-positive status (OR: 1.84; 95% CI: 1.10-3.36) and alcohol intake ≥150 g/day (OR: 2.01; 95% CI: 1.10-3.66) as independent risk factors for high risk of mortality. CONCLUSION The anti-HBc-positive state is associated with more advanced liver disease in alcoholic patients with cirrhosis. A prospective study including HBV-DNA testing and liver biopsies should be considered to validate and further elucidate these findings.

Abstract
BACKGROUND & AIMS Adherence to antiviral treatment is important to achieve sustained virological response (SVR) in chronic hepatitis C (CHC). We evaluated the efficiency of a multidisciplinary support programme (MSP), based on published HIV treatment experience, to increase patient adherence and the efficacy of pegylated interferon alfa-2a and ribavirin in CHC. METHODS 447 patients receiving antiviral treatment were distributed into 3 groups: control group (2003-2004, n=147), MSP group (2005-2006, n=131), and MSP-validation group (2007-2009, n=169). The MSP group included two hepatologists, two nurses, one pharmacist, one psychologist, one administrative assistant, and one psychiatrist. Cost-effectiveness analysis was performed using a Markov model. RESULTS Adherence and SVR rates were higher in the MSP (94.6% and 77.1%) and MSP-validation (91.7% and 74.6%) groups compared to controls (78.9% and 61.9%) (p<0.05 in all cases). SVR was higher in genotypes 1 or 4 followed by the MSP group vs. controls (67.7% vs. 48.9%, p=0.02) compared with genotypes 2 or 3 (87.7% vs. 81.4%, p=n.s.). The MSP was the main predictive factor of SVR in patients with genotype 1. The rate of adherence in patients with psychiatric disorders was higher in the MSP groups (n=95, 90.5%) compared to controls (n=28, 75.7%) (p=0.02). The cost per patient was € 13,319 in the MSP group and € 16,184 in the control group. The MSP group achieved more quality-adjusted life years (QALYs) (16.317 QALYs) than controls (15.814 QALYs) and was dominant in all genotypes. CONCLUSIONS MSP improves patient compliance and increases the efficiency of antiviral treatment in CHC, being cost-effective.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Calotropis gigantiea (L.) R. Br (Apocynaceae) commonly called as "crown flower" or "giant milk weed" is a well-known weed to many cultures for treating various disorders related to central nervous system, skin diseases, digestive system, respiratory system, reproductive system etc. Indigenous groups made the plant as a part of their lives since they use the fruit fibre to make ropes, household items, for weaving clothes and flowers for garlands apart from usage for various indications. The study aims at far-reaching review on phytochemistry, pharmacological activities, ethnopharmacology, intellectual property transfer on pharmacological therapies, toxicity which aids to provide scientific evidence for the ethnobotanical claims and to identify gaps required to be conducted as a future research prerequisite. MATERIALS AND METHODS A systematic literature search was performed using different databases such as Scopus, Science direct, PubMed and Sciverse with no timeline limit set during the search. All the available abstracts and full text articles were included in the systematic review. RESULTS Most of the folkloric uses were validated by the scientific studies such as analgesic, anti-arthritic, anti-asthmatic, anti-bacterial, anti-convulsant, anti-pyretic, central nervous system disorders, contraceptive, anti-ulcer and wound healing. In addition other studies such as anti-diabetic, anti-diarrhoeal, anti-helminthic, anti-histamine, anti-inflammatory, anti-microbial, anti-oxidant, cardio-protective studies, cytotoxicity, hepatoprotectivity, fibrinolytic, mosquitocidal, nerve muscle activity, vasodilation and skeletal muscle activities were also reported for the plant. Isolated compounds such as calotropin, frugoside and 4'-O-β-D-glucopyranosyl frugoside were tested for the cytotoxicity efficacy against both human and rat cell lines out of which calotropin showed potent activity (IC50-15 ng/ml). However there were no clinical trials reported on the plant which is one of the major lacunas. CONCLUSIONS This review article explores the ethnopharmacological, pharmacological activities phytochemistry and intellectual rights of Cg which gives the evidence of a potent and commercial drug which up on further research leads to the most viable drug for variety of treatments. However there is further need for in-vivo studies and clinical trials on isolated phytoconstituents which will help to commercialise.

Abstract
INTRODUCTION Central venous catheters (CVC) related thrombosis (CRT) represents a well known complication in patients with acute myeloid leukemia (AML) receiving intensive chemotherapy but the efficacy of antithrombotic prophylaxis still remains controversial. PATIENTS AND METHODS We analyzed 71 consecutive AML patients whose CVC was inserted before each chemotherapy cycle for an overall number of 106 CVC placements. In 47/106 insertions, a prophylaxis with 100 IU/kg/day low molecular weight heparin (LMWH) was administered for 7 days after CVC insertion and additional 7 after CVC removal. This unconventional dose of LMWH, although higher than usual, appeared adequate for a short-course approach. LMWH was delivered regardless of the platelet (PLT) count once provided that it should have been maintained above 20 x 10(9)/L by transfusions. RESULTS Of 106 insertions, we observed 19 (18%) episodes of CRT, 58 (54%) of sepsis and 50 (47%) infections of CVC-exit site with no difference between LMWH and no-LMWH group. Occurrence of CRT was significantly associated with CVC-exit site infections (14/19, p=0.01) and sepsis (16/19, p=0.005) with no difference between LMWH and no-LMWH group. In multivariate analysis, both CVC-exit site infections and sepsis were confirmed to be independent risk factors for CRT development. CONCLUSION Our retrospective study, although based on a small sample size, suggests that the occurrence of CVC-exit site infections and neutropenic sepsis following chemotherapy significantly increases the risk of CRT in AML, independently from the use of LMWH prophylaxis.

Abstract
Brucine is an alkaloid derived from the seeds of Strychnos nux-vomica Linn. which have long been used as a traditional medicine for the treatment of hepatocellular carcinoma (HCC) in China. HCC prognosis can be greatly influenced by metastasis. There has thus far been little research into brucine as a source of anti-metastasis activity against HCC. In this study, we revealed that brucine dramatically repressed HepG2 and SMMC-7721 HCC cell migration with few cytotoxic effects. Hypoxia inducible factor 1 (HIF-1) is a key transcription factor mediating cell migration and invasion. Brucine suppressed HIF-1-dependent luciferase activity in HepG2 cells. The transcriptions of four known HIF-1 target genes involved in HCC metastasis, i.e., fibronectin, matrix metallopeptidase 2, lysyl oxidase, and cathepsin D, were also attenuated after brucine treatment. Experiments in vivo showed that an intraperitoneal injection of 5 and 15 mg/kg of brucine resulted in dose-dependent decreases in the lung metastasis of H22 ascitic hepatoma cells. Moreover, a dosage of brucine at 15 mg/kg exhibited very low toxic effects to tumor-bearing mice. Consistently, brucine downregulated expression levels of HIF-1 responsive genes in vivo. Our current study demonstrated the capacity of brucine in suppressing HCC cell migration in vitro and lung metastasis in vivo. The inhibition of the HIF-1 pathway is implicated in the anti-metastasis activity of brucine.

Abstract
The demand for human monocyte-derived dendritic cells (moDCs), as well as for primary human B and T lymphocytes for immunological research purposes has been increased in recent years. Classically, these monocytes are isolated from blood, leukapheresis products or buffy coats of healthy donors by plastic adherence of peripheral blood mononuclear cells (PBMCs), followed by stimulation with granulocyte macrophage colony-stimulating factor (GM-CSF) and interleukin (IL)-4, while lymphocytes are usually isolated from the non-adherent fraction (NAF) by magnetic cell sorting. However, donor-blood is a limited resource and not every blood bank offers leukapheresis products or buffy coats for laboratory use. Additionally, a leukapheresis is very expensive and also the generation/isolation of cells is time- and cost-intensive. To overcome some of these obstacles, we evaluated if low-cost leukoreduction system chambers (LRSCs), which arise after routine donor plateletpheresis procedures, and are usually discarded, would be an alternative and appropriate source of PBMCs to generate moDCs and to isolate lymphocytes. By analyzing the number and phenotype of immature and mature dendritic cells (DCs), as well as of B and T lymphocytes derived from LRSCs, we found all cells to be of high quantity and quality. Further investigations on DCs comprising transwell migration assays, allogeneic mixed lymphocyte reactions (MLR), cytokine secretion assays, and cytotoxic T cell induction assays revealed high migratory, as well as stimulatory capacity of these cells. In addition, DCs and T cells were efficiently electroporated with mRNA and showed characteristic cytokine production after co-culture, demonstrating LRSCs as an efficient, valid, and economic source for generation of moDCs and lymphocytes for research purposes.

Abstract
The aryl hydrocarbon receptor (AHR) is a ligand-activated transcription factor which plays a role in the development of multiple tissues and is activated by a large number of ligands, including 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). In order to examine the roles of the AHR in both normal biological development and response to environmental chemicals, an AHR knockout (AHR-KO) rat model was created and compared with an existing AHR-KO mouse. AHR-KO rats harboring either 2-bp or 29-bp deletion mutation in exon 2 of the AHR were created on the Sprague-Dawley genetic background using zinc-finger nuclease (ZFN) technology. Rats harboring either mutation type lacked expression of AHR protein in the liver. AHR-KO rats were also insensitive to thymic involution, increased hepatic weight and the induction of AHR-responsive genes (Cyp1a1, Cyp1a2, Cyp1b1, Ahrr) following acute exposure to 25 μg/kg TCDD. AHR-KO rats had lower basal expression of transcripts for these genes and also accumulated ~30-45-fold less TCDD in the liver at 7 days post-exposure. In untreated animals, AHR-KO mice, but not AHR-KO rats, had alterations in serum analytes indicative of compromised hepatic function, patent ductus venosus of the liver and persistent hyaloid arteries in the eye. AHR-KO rats, but not AHR-KO mice, displayed pathological alterations to the urinary tract: bilateral renal dilation (hydronephrosis), secondary medullary tubular and uroepithelial degenerative changes and bilateral ureter dilation (hydroureter). The present data indicate that the AHR may play significantly different roles in tissue development and homeostasis and toxicity across rodent species.

Abstract
UNLABELLED In this study, carboxylic acid functionalized single walled carbon nanotubes (f-SWCNT-COOH) was shown to support the viability and ex vivo expansion of freeze-thawed, non-enriched hematopoietic stem and progenitor cells (HSPC) in human umbilical cord blood-mononucleated cells (UCB-MNC). Our in vitro experiments showed that f-SWCNT-COOH increased the viability of the CD45(+) cells even without cytokine stimulation. It also reduced mitochondrial superoxides and caspase activity in CD45(+) cells. f-SWCNT-COOH drastically reduced the proportions of CD45(-) cells in the non-enriched UCB-MNC. Phenotypic expression analysis and functional colony forming units (CFU) showed significant ex vivo expansion of HSPC, particularly of CD45(+)CD34(+)CD38(-) population and granulocyte-macrophage (GM) colonies, in f-SWCNT-COOH augmented cultures supplemented with basal cytokines. In vivo data suggested that f-SWCNT-COOH expanded UCB-MNC could repopulate immunodeficient mice models with minimal acute or sub-acute symptoms of graft-versus-host disease (GVHD) and f-SWCNT-COOH dependent toxicity. FROM THE CLINICAL EDITOR In this paper a novel method is presented by using single wall functionalized carbon nanotubes to enhance viability and ex vivo expansion of freeze-thawed, non-enriched hematopoietic stem and progenitor cells in human umbilical cord blood -mononucleated cells. Detailed data is presented about enhanced viability, including improved repopulation of immunodeficient mice models with minimal acute or sub-acute symptoms of graft-versus-host disease.
