“Amyloid precursor protein (APP) is

processed sequentially by the beta-site APP cleaving enzyme and gamma-secretase to generate amyloid beta (A beta) peptides, one of the hallmarks of Alzheimer’s disease. The intracellular location of A beta production-endosomes or the trans-Golgi network (TGN)-remains uncertain. We investigated the role of different postendocytic trafficking events in A beta(40) production using an RNAi approach. Depletion of Hrs and Tsg101, acting early in the multivesicular body pathway, retained APP in early endosomes and reduced A beta(40) production. Conversely, depletion of CHMP6 and VPS4, acting selleck kinase inhibitor late in the pathway, rerouted

endosomal APP to the TGN for enhanced APP processing. We found that VPS35 (retromer)-mediated APP recycling to the GW2580 TGN was required for efficient A beta(40) production. An interruption of the bidirectional trafficking of APP between the TGN and endosomes, particularly retromer-mediated retrieval of APP from early endosomes to the TGN, resulted in the accumulation of endocytosed APP in early endosomes with reduced APP processing. These data suggest that A beta(40) is generated predominantly in the TGN, relying on an endocytosed pool of APP recycled from early endosomes Selleckchem YAP-TEAD Inhibitor 1 to the TGN.”
“A failure diagram that combines the thresholds for failure of a smooth specimen to that of a fracture mechanics specimen, similar to the modified Kitagawa diagram in fatigue, is presented. For a given material/environment system, the diagram defines conditions under which a crack initiated at the threshold stress in a smooth specimen becomes a propagating crack, by satisfying the threshold stress intensity of a long crack. In analogy with fatigue, it is shown that internal

stresses or local stress concentrations are required to provide the necessary mechanical crack tip driving forces, on one hand, and reaction/transportation kinetics to provide the chemical potential gradients, on the other. Together, they help in the initiation and propagation of the cracks. The chemical driving forces can be expressed as equivalent mechanical stresses using the failure diagram. Both internal stresses and their gradients, in conjunction with the chemical driving forces, have to meet the minimum magnitude and the minimum gradients to sustain the growth of a microcrack formed. Otherwise, nonpropagating conditions will prevail or a crack formed will remain dormant. It is shown that the processes underlying the crack nucleation in a smooth specimen and the crack growth of a fracture mechanics specimen are essentially the same. Both require building up of internal stresses by local plasticity.

In addition, cELISA identified 22.2 %, 22.2 % and 6.2 % infection rates with B. bigemina, Babesia bovis and mixed infection, respectively in buffaloes. The semi-nested PCR assay showed that 15 % of the tested samples were positive for Babesia bovis in cattle, but just 3 % in buffaloes. Infections with B. bigemina were also found in cattle (32.4 %), but not in buffaloes upon see more nested PCR analysis. Sequencing analysis confirmed the identity of the PCR amplicons and showed that Egyptian genotypes of B. bigemina and Babesia bovis highly resemble sequences previously deposited in GenBank. Hemograms

performed on the sampled animals revealed macrocytic hypochromic anemia associated with reduced platelet counts in infected cattle with babesiosis. In addition, marked increases in total leukocyte and granulocytic counts and decreases in lymphocytic counts were found in infected cattle. In contrast, no such hematological anomalies were found in presumably Babesia-infected buffaloes. Conclusions: Frequent occurrence of babesiosis among apparently healthy bovines in Egypt, suggests the need for appropriately designed prevalence studies in THZ1 concentration this country. Infected bovine, but not buffalo, populations often

present hematological disorders compatible with intravascular hemolysis and thrombocytopenia.”
“Background: Q waves on a 12-lead electrocardiography (ECG) are considered to be classic hallmarks of prior myocardial infarction. However, one study suggested that the fragmented QRS complex (fQRS) on ECG is a highly sensitive and specific marker of myocardial scarring on a nuclear stress test. The study aimed to investigate the diagnostic accuracy of fragmented selleck kinase inhibitor QRS complexes compared with Q waves for myocardial injury detected by delayed contrast-enhanced

cardiovascular magnetic resonance imaging (DE-CMRI) in subjects with acute myocardial infarction.\n\nMethods: Electrocardiograms of 190 subjects with myocardial infarction who underwent DE-CMR were analyzed. fQRS was defined by the presence of an additional R wave (R.), or notching of the S wave, or more than one R’ in two contiguous leads.\n\nResults: Delayed enhancement was observed in 180 (94.7%) patients. Transmural enhancement was noted in 78 (43.3%) and subendocardial enhancement in 102 (56.7%) patients. The sensitivity and specificity of Q waved and fQRS for diagnosing delayed enhancement were 59.4% vs. 66.7% and 90.0% vs. 40.0%. The area under the receiver-operator characteristics curve of delayed enhancement was 0.75 for Q waves and 0.53 for fQRS (p = 0.04). The areas under the ROC curves of the transmurality of delayed enhancement were 0.44 for fQRS and 0.58 for Q waves (p = 0.73).\n\nConclusions: fQRS has poor accuracy for the detection of myocardial injury compared with Q waves. fQRS and Q waves are not valuable tools for the diagnosis transmural irreversible myocardial injury in acute myocardial infarction.

The results showed that the proposed pulse enhancement algorithm improved (p < 0.05) pulse onset detection according to all three different onset definitions and for all three types of pulsatile signals as compared to results without using the pulse enhancement. These results suggested that the proposed algorithm could help achieve robustness in pulse onset detection and facilitate pulse wave analysis using clinical recordings. (c) 2008 IPEM.

“A 71-year-old man diagnosed with lung cancer in the right lower lobe with invasion to the middle lobe underwent right lower and middle lobectomy with mediastinal lymph node dissection. The cancer was pathologically diagnosed as stage IIB (pT3N0M0) with combined squamous cell carcinoma and an atypical carcinoid tumour. To the best of our knowledge, this is the first report of a combined atypical carcinoid tumour and non-small cell lung cancer. This case further expands the histological spectrum of combined neuroendocrine tumours.”
“The mode of action of Delta lac-acetogenins, strong inhibitors of bovine heart Selleckchem GNS-1480 mitochondrial complex I, is different from that of traditional inhibitors such as rotenone and piericidin A [Murai, M., et al. (2007) Biochemistry 46, 6409-6416]. As further exploration of these unique inhibitors might provide new insights into the terminal electron transfer step

of complex I, we drastically modified the structure of Delta lac-acetogenins and characterized their inhibitory action. In particular, on the basis of structural similarity between the bis-THF and the piperazine rings, we here synthesized a series of piperazine derivatives. Some Sapitinib of the derivatives exhibited very potent inhibition at nanomolar levels. The hydrophobicity

of the side chains and their balance were important structural factors for the inhibition, as is the case for the original Delta lac-acetogenins. However, unlike in the case of the original Delta lac-acetogenins, (i) the presence of two hydroxy groups is not crucial for the activity, (ii) the level of superoxide production induced by the piperazines is relatively high, (iii) the inhibitory potency for the reverse electron transfer is remarkably weaker than that for the forward event, and (iv) the piperazines efficiently suppressed the specific binding of a photoaffinity probe of natural-type acetogenins ([(125)I]TDA) to the ND1 subunit. We therefore conclude that the action mechanism of the piperazine series differs from that of the original Delta lac-acetogenins. The photoaffinity labeling study using a newly synthesized photoreactive piperazine ([(125)I]AFP) revealed that this compound binds to the 49 kDa subunit and an unidentified subunit, not ND1, with a frequency of similar to 1:3. A variety of traditional complex I inhibitors as well as Delta lac-acetogenins suppressed the specific binding of [(125)I]AFP to the subunits.

“Compartmentalization is essential for a brain area to be involved in different functions through topographic afferent and efferent connections that reflect this organization. The adult cerebellar cortex is compartmentalized into longitudinal stripes, in which Purkinje cells (PCs) have compartment-specific molecular expression profiles. How these compartments form during development is generally not understood. To investigate this process, we focused on the late developmental stages of the cerebellar compartmentalization that occur from embryonic day 17.5 (E17.5), when embryonic compartmentalization Epigenetic signaling inhibitor is evidently observed, to postnatal

day 6 (P6), when adult-type compartmentalization begins to be established.

The transformation between these compartmentalization patterns was analyzed JNK-IN-8 ic50 by mapping expression patterns of several key molecular markers in serial cerebellar sections in the mouse. A complete set of 54 clustered PC subsets, which had different expression profiles of FoxP2, PLC beta 4, EphA4, Pcdh10, and a reporter molecule of the 1NM13 transgenic mouse strain, were distinguished in three-dimensional space in the E17.5 cerebellum. Following individual PC subsets during development indicated that these subsets were rearranged from a clustered and multilayered configuration to a flattened, single-layered and striped configuration by means of transverse slide, longitudinal split, or transverse twist spatial transformations during development. The Purkinje

cell-free spaces that exist between clusters at E17.5 become granule cell raphes that separate striped compartments at P6. The results indicate that the similar to 50 PC clusters of the embryonic cerebellum will ultimately become the longitudinal compartments of the adult cerebellum after undergoing various peri-and postnatal transformations that alter their relative spatial relationships.”
“The ERM proteins (ezrin, radixin and moesin) are known for connecting the actin cytoskeleton to the plasma membrane. They have been found to associate with lipid rafts as well as to be important for endosomal sorting and receptor signaling. However, little is known about the role of ERM proteins in retrograde transport and lipid homeostasis. In this study, we show that ezrin and moesin are important for efficient cell surface association of Shiga Topoisomerase inhibitor toxin (Stx) as well as for its retrograde transport. Furthermore, we show that depletion of these proteins influences endosomal dynamics and seems to enhance Stx transport toward lysosomes. We also show that knockdown of Vps11, a subunit of the HOPS complex, leads to increased retrograde Stx transport and reverses the inhibiting effect of ezrin and moesin knockdown. Importantly, retrograde transport of the plant toxin ricin, which binds to both glycolipids and glycoproteins with a terminal galactose, seems to be unaffected by ezrin and moesin depletion.

On a 10-point scale indicating pain during treatment, participants rated ICG+DL therapy to be more painful (61 +/- 20) than Nd:YAG laser (54 +/- 20).\n\nConclusions ICG+DL therapy represents a new and promising treatment modality for TLV, with high clearance rates and a very good cosmetic outcome after one single treatment session.”
“Objective:

The aim of this study was to determine the association between serum albumin and the severity of microvascular complications and presence of coronary artery disease in type 2 diabetic patients. Patients and Methods: The presence of diabetic complications was assessed in a total Emricasan Apoptosis inhibitor of 130 Japanese patients with type 2 diabetes mellitus. Retinopathy was classified as absent, simple or proliferative diabetic retinopathy. Neuropathy was considered to be present when the patient showed absence of Achilles tendon reflex, and also evaluated by measuring the median motor nerve

conduction velocity (MNCV) in the nerve conduction study. Results: In relation to retinopathy, there were 83 patients with no retinopathy (absent), 26 with simple retinopathy and 21 with proliferative retinopathy. There was a significant difference in the serum albumin level between the “absent” group and the other two groups. In relation to nephropathy, there were 68 patients with no evidence of nephropathy, 49 with microalbuminuria and 13 with proteinuria. The results of logistic regression analysis with adjustment for three Acalabrutinib cost variables (age, gender, serum CRP) revealed that serum albumin was independently related to proliferative retinopathy and proteinuria. In relation to neuropathy, serum albumin was found to be significantly related to the absence RWJ 64809 of Achilles tendon reflex, MNCV, and MFWL. The results of multiple regression analysis with adjustment for three variables (age, gender, serum CRP) revealed that serum albumin was independently related

to MNCV and MFWL. Conclusions: Serum albumin was significantly associated with the severity of retinopathy and neuropathy.”
“A taste associated with emetic drugs produces conditioned disgust reactions in rats (predominantly gaping), unlike nonemetic drugs that can still produce conditioned taste avoidance but not conditioned disgust. That difference suggests nausea is a prerequisite for learning disgust reactions to tastes. Depletion of forebrain serotonin (5-HT) by 5,7-dihydroxytryptamine (5,7-DHT) lesions of the dorsal raphe nucleus and median raphe nucleus prevents LiCl-induced conditioned disgust reactions (Limebeer et al., 2004). Herewedemonstrate that partial depletion of 5-HT in the insular cortex (IC) prevents LiCl-induced conditioned disgust reactions. Furthermore, a double dissociation occurred in the partial regulation of disgust and taste avoidance by selective 5-HT3 receptor antagonism/agonism in the posterior (granular) region of the IC and the anterior (dorsal agranular) region of the IC, respectively.

The TZD ring was replaced with: a mercaptoacetic acid group [[[(3,5-dichlorophenyl)amino]carbonyl]thio]acetic acid, DCTA; a methylated TZD ring [3-(3,5-dichlorophenyl)-5-methyl-2,4-thiazolidinedione, DPMT]; and isomeric thiazolidinone rings [3-(3,5-dichlorophenyl)-2- and 3-(3,5-dichlorophenyl)-4-thiazolidinone,

2-DCTD and 4-DCTD, respectively]. The following phenyl ring-modified analogs were also tested: 3-phenyl-, 3-(4-chlorophenyl)-, 3-(3,5-dimethylphenyl)- and 3-[3,5-bis(trifluoromethyl)phenyl]-2,4-thiazolidinedione (PTZD, CPTD, DMPT and DFMPT, respectively). Toxicity was assessed in male Fischer 344 rats 24 h after administration of the compounds. In the TZD series only DPMT produced liver damage, as evidenced by elevated serum A-1155463 purchase alanine aminotransferase (ALT) activities at 0.6 and 1.0 mmol kg-1 (298.6 +/- 176.1 and 327.3 +/- 102.9 Sigma-Frankel units ml-1, respectively) vs corn oil controls (36.0 +/- 11.3) and morphological changes in liver Selleckchem IPI145 sections. Among the phenyl analogs, hepatotoxicity was observed in rats administered PTZD, CPTD and DMPT; with ALT values

of 1196.2 +/- 133.6, 1622.5 +/- 218.5 and 2071.9 +/- 217.8, respectively (1.0 mmol kg(-1) doses). Morphological examination revealed severe hepatic necrosis in these animals. Our results suggest that hepatotoxicity of these compounds is critically dependent on the presence of a TZD ring and also the phenyl substituents. Copyright (C) 2011 John Wiley & Sons, Ltd.”
“The targets of broadly cross-neutralizing (BCN) antibodies are of great interest in the HIV vaccine field. We have identified a subtype C HIV-1-superinfected individual, CAP256, with high-level BCN activity, and characterized the antibody specificity mediating breadth. CAP256 developed potent BCN activity peaking at 3 years postinfection, neutralizing 32 (76%) of 42 heterologous viruses, with titers of antibodies against some viruses exceeding 1:10,000. CAP256 showed a subtype bias, preferentially

neutralizing subtype C and A viruses over subtype B viruses. CAP256 BCN serum targeted a quaternary epitope which included the V1V2 region. Further mapping identified residues F159, N160, L165, R166, D167, K169, and K171 (forming the FN/LRD-K-K motif) in the V2 region as crucial to the CAP256 epitope. However, this website the fine specificity of the BCN response varied over time and, while consistently dependent on R166 and K169, became gradually less dependent on D167 and K171, possibly contributing to the incremental increase in breadth over 4 years. The presence of an intact FN/LRD-K-K motif in heterologous viruses was associated with sensitivity, although the length of the adjacent V1 loop modulated the degree of sensitivity, with a shorter V1 region significantly associated with higher titers. Repair of the FN/LRD-K-K motif in resistant heterologous viruses conferred sensitivity, with titers sometimes exceeding 1: 10,000.

\n\nSoil properties and vegetation composition were analyzed

for several sites underlain by serpentinite, gabbro, and calc-schist this website substrates and correlated using direct and indirect statistical methods.\n\nBoreal forest soils were well-developed and tended to have low pH throughout the soil profile resulting in high Ni availability. Alpine soils, in comparison, were less developed. The distinct serpentine plant communities of the Western Alps are most strongly correlated with high levels of bioavailable Ni associated with low soil pH. Other factors such as macronutrient deficiency, low Ca:Mg molar ratio and drought appear to be less important.\n\nThe strong ecological influence of Ni is caused by environmental conditions which increase metal mobilization.”
“The Alzheimer’s disease-linked gene presenilin is required for intramembrane proteolysis of amyloid-beta precursor protein, contributing to the pathogenesis of neurodegeneration that is characterized by loss of neuronal connections, but the role of Presenilin in establishing neuronal selleck chemical connections is less clear. Through a forward genetic screen in mice

for recessive genes affecting motor neurons, we identified the Columbus allele, which disrupts motor axon projections from the spinal cord. We mapped this mutation to the Presenilin-1 gene. Motor neurons and commissural interneurons in Columbus mutants lacking Presenilin-1 acquire an inappropriate attraction to Netrin produced by the floor plate because of an accumulation p38 MAPK inhibitor of DCC receptor fragments within the membrane that are insensitive to Slit/Robo silencing. Our findings reveal that Presenilin-dependent DCC receptor processing coordinates the interplay between Netrin/DCC and Slit/Robo signaling. Thus, Presenilin is a key neural circuit builder that gates the spatiotemporal pattern of guidance signaling, thereby ensuring neural projections occur with high fidelity.”
“We investigated the strength of

the association between oxidative stress, hypoxia inducible factor I (HIFI a) and acute hypoxic ventilatory response (AHVR) after hypoxic training in elite runners.\n\nSix elite runners were submitted to 18-day of “living high-training low” (LHTL) and six performed the same training in normoxia. AHVR was measured during an acute hypoxic test before and after training. Plasma levels of protein oxidation (AOPP), malondialdehydes and (HIF-1 alpha) mRNA in the leukocytes were measured before and after the acute hypoxic test.\n\nLHTL increased AHVR and amplified the responses of HIF-1 alpha mRNA and AOPP (Delta(AOPP)) to the acute hypoxic test. Furthermore, between PRE and POST, the changes in Delta(AOPP) were correlated with the changes in AHVR (r = 0.69, P = 0.01).\n\nThe ventilatory acclimatization to hypoxia occurring in athletes after LHTL seems to be modulated by oxidative stress. Furthermore, LHTL induced a higher sensitivity of HIF-1 alpha mRNA to acute hypoxia in elite athletes. (C) 2009 Elsevier B.V. All rights reserved.

For that, plasma cortisol and melatonin concentrations, pineal melatonin concentrations, pineal traits (weight and volume), density and volume of pinealocytes (immunolabelled with synaptophysin) and if interstitial astrocyte-like cells (immunolabelled with the GFAP) were assessed in 32 Verata goat kids, 4 day old at the beginning of the experiment, early weaned (when they were 6 day old, n = 16) or not weaned (n = 16) whose half of them in each group were implanted with melatonin for 28 days. Whereas the cortisolemia was significantly higher in early-weaned kids that in not weaned ones, the Trichostatin A in vivo melatonin concentrations in plasma and in the pineal tissue were dramatically reduced. Moreover,

the pineal morphology (weight Wnt inhibitor and volume) and pinealocyte and interstitial cell density and volume were also markedly depressed when kids were early weaned. The melatonin treatment has partially restored the morphology and function of the pineal gland and reduced the cortisolemia in stressed kids while it has globally no effect in the not weaned animals. These results indicated that melatonin implantation could play an important role in the improvement of the pineal function and indirectly in the regulation of the cortisol secretion in stressed (early weaned) goat kids.”
“The aim

of this clinical study was to assess speech recognition in noise after cochlear implantation in subjects with single-sided deafness and incapacitating tinnitus. 20 subjects complaining of severe intractable tinnitus unresponsive to treatment received a MED-EL cochlear implant (CI). 11 subjects had normal hearing (NH group) on the contralateral side, while 9 used a hearing aid (HA group). The subjects were tested in noise in two listening conditions, i.e. with their acoustic hearing only and with adding the CI to the acoustic hearing (binaural). Subjective improvement in daily life was evaluated using the Speech Spatial and Qualities Hearing Scale (SSQ). The summation effect (3.3 dB for the HA group and 0.6 dB for the

NH group) is not significant in both groups. A significant squelch effect of adding the CI was seen for the HA users (3.8 dB), but not for the NH group (1.2 dB). Additionally, a significant effect of adding the CI was found Cl-amidine for the spatial configuration where noise is presented in front and speech on the CI side for both the HA group (6.5 dB) and the NH group (1.7 dB). Results of the SSQ show a significant overall benefit of wearing the CI for both groups. The preliminary results of these 20 subjects suggest that cochlear implantation can improve hearing in people suffering from single-sided deafness combined with tinnitus. Copyright (C) 2008 S.

“Organisation in eusocial insect colonies emerges from the decisions and actions of its individual members.

In the present study,

we performed experiments on rabbits exposed to 2.45-GHz MWs. A total of 24 measurements were conducted for power densities from approximately 100 to 1000 W/m(2). Our computational code for electromagnetic-thermal dosimetry was used to set the exposure time duration and incident power density. Our experimental results suggest that a core temperature elevation of 1 degrees GSK1210151A Epigenetics inhibitor C is an estimate of the threshold-inducing complex behavioral signs of MW-induced thermal stress in rabbits for different whole-body average SARs and exposure time durations. The whole-body average SAR required for MW-induced behavioral sign in rabbits was estimated as approximately 1.3 W/kg for 2.45-GHz MWs.”
“3-Deoxyglucosone (3-DG), a reactive I,2-dicarbonyl compound derived from D-glucose in food and in vivo, is an important precursor for advanced glycation endproducts (AGEs). At present, virtually no information about the metabolic transit of dietary 3-DG is available. One possible metabolic

pathway of 3-DG during digestion is enzymatic transformation to less reactive compounds such as 3-deoxyfructose (3-DF). To study the handling of dietary 1,2-dicarbonyl compounds by the human Autophagy Compound Library body, 24 h urinary excretion of 3-DG and its metabolite, 3-deoxyfructose, was investigated. Urinary 3-DG and 3-DF excretion was monitored for nine healthy volunteers following either a diet with no dietary restrictions or a diet avoiding the ingestion of 3-DG and other Maillard reaction products (“raw food” diet). During the “raw food” diet, the urinary 3-DG and 3-DF excretion decreased approximately to 50% compared to the excretions during the diet with no

restrictions. When subjects received a single dose of wild honey (50 g) naturally containing a defined amount of 3-DG (505 mu mol), Selleck LY2835219 median excretion of 3-DG and 3-DF increased significantly from 4.6 and 77 to 7.5 and 147 mu mol/day, respectively. The obtained experimental data for the first time demonstrate a dietary influence on urinary 3-DG and 3-DF levels in healthy human subjects.”
“A high throughput screening assay was developed to determine the total dimer level in antibody samples. This method utilizes high speed microchip electrophoresis separation following chemical cross-linking. Upon reacting with homobifunctional N-hydroxysuccinimide-esters (NHS-esters), covalent linkages can be established between the primary amines of two neighboring antibody molecules. The reaction conditions are optimized to achieve quantitative cross-linking of only physically associated monomers within an antibody dimer. The resulting cross-linked dimers, originating from either covalent or non-covalent antibody dimers, can then be separated from monomers by SDS electrophoresis. A commercial microchip electrophoresis instrument is used for high speed separation, allowing each sample to be analyzed in about 1 min.

\n\nMethods Fifty-eight women with PCOS were randomly assigned to two groups. Metformin group (29) was treated with metformin mono-therapy and metformin plus rosiglitazone group (29) was treated with metformin plus rosiglitazone for 6 months. Treatment

was discontinued once pregnancy was diagnosed.\n\nResults Fasting insulin, postprandial insulin, the homeostatic model assessment of insulin resistance (HOMA-IR), luteinizing hormone Dinaciclib cell line (LH), triglyceride, lower density cholesterol and testosterone level decreased significantly in both groups (P <0.05). Metformin plus rosiglitazone had a better effect than metformin mono-therapy. Body mass index decreased by 7.8% in metformin group while no significant change in metformin plus rosiglitazone group. There were eight pregnancies, six in metformin plus rosiglitazone group (one abortion) and two in metformin group. There was no congenital anomaly at birth and seven infants developed well at one year’s follow-up.\n\nConclusions Metformin can improve insulin resistance and imbalance of endocrine hormones. Metformin

plus rosiglitazone has a more pronounced therapeutic effect and achieved more pregnancies than mono-therapy with metformin. The use of metformin and rosiglitazone before pregnancy has no obvious side effect on the development of the infants. Our study might suggest that metformin is the better choice in PCOS patients with serious obese and rosiglitazone plus metformin would be more effective in patients with severe insulin resistance or those do not respond to metformin.

“The microphase adsorption-spectral correction (MPASC) technique was described and PARP inhibitor applied to the study of the interactions of sodium octanesulfonate (SOS) with human serum albumin (HSA). The aggregation SOS obeys the Vorinostat manufacturer Langmuir monolayer adsorption. The results show the adsorption ratio of sodium octanesulfonate to HSA is SOS:HSA=18:1.

“A series of room temperature ionic liquids (ILs), in which cholinium acts as the cation and amino acids as the anions, were prepared via a simple and green chemical route, and characterized. Most of the ILs dissolved lignin efficiently and selectively (with solubilities of 140-220 mg of lignin per g of IL). The solubility of xylan in these ILs (which ranged from <1 to 85 mg g(-1)) depended on the nature of the anion, while cellulose was scarcely soluble (<5mg g(-1)). In addition, enzymatic hydrolysis of microcrystalline cellulose and rice straw was enhanced significantly after pretreatment using the IL [Ch][Gly].”
