Abstract
Despite progressive improvements in the survival rate of pediatric B-cell lineage acute lymphoblastic leukemia (B-ALL), chemoresistance-induced disease progression and recurrence still occur with poor prognosis, thus highlighting the urgent need to eradicate drug resistance in B-ALL. The 6-mercaptopurine (6-MP) is the backbone of ALL combination chemotherapy, and resistance to it is crucially related to relapse. The present study couples chemoresistance in pediatric B-ALL with histidine metabolism deficiency. Evidence was provided that histidine supplementation significantly shifts the 6-MP dose-response in 6-MP-resistant B-ALL. It is revealed that increased tetrahydrofolate consumption via histidine catabolism partially explains the re-sensitization ability of histidine. More importantly, this work provides fresh insights into that desuccinylation mediated by SIRT5 is an indispensable and synergistic requirement for histidine combination therapy against 6-MP resistance, which is undisclosed previously and demonstrates a rational strategy to ameliorate chemoresistance and protect pediatric patients with B-ALL from disease progression or relapse.

Abstract
Pseudomonas aeruginosa is an opportunistic gram-negative pathogenic microorganism that poses a significant challenge in clinical treatment. Antibiotics exhibit limited efficacy against mature biofilm, culminating in an increase in the number of antibiotic-resistant strains. Therefore, novel strategies are essential to enhance the effectiveness of antibiotics against Pseudomonas aeruginosa biofilms. D-histidine has been previously identified as a prospective anti-biofilm agent. However, limited attention has been directed towards its impact on Pseudomonas aeruginosa. Therefore, this study was undertaken to explore the effect of D-histidine on Pseudomonas aeruginosa in vitro. Our results demonstrated that D-histidine downregulated the mRNA expression of virulence and quorum sensing (QS)-associated genes in Pseudomonas aeruginosa PAO1 without affecting bacterial growth. Swarming and swimming motility tests revealed that D-histidine significantly reduced the motility and pathogenicity of PAO1. Moreover, crystal violet staining and confocal laser scanning microscopy demonstrated that D-histidine inhibited biofilm formation and triggered the disassembly of mature biofilms. Notably, D-histidine increased the susceptibility of PAO1 to amikacin compared to that in the amikacin-alone group. These findings underscore the efficacy of D-histidine in combating Pseudomonas aeruginosa by reducing biofilm formation and increasing biofilm disassembly. Moreover, the combination of amikacin and D-histidine induced a synergistic effect against Pseudomonas aeruginosa biofilms, suggesting the potential utility of D-histidine as a preventive strategy against biofilm-associated infections caused by Pseudomonas aeruginosa.

Abstract
Sepsis is a major cause of death worldwide, with a mortality rate that has remained stubbornly high. The current gold standard of risk stratifying sepsis patients provides limited mechanistic insight for therapeutic targeting. An improved ability to predict sepsis mortality and to understand the risk factors would allow better treatment targeting. Sepsis causes metabolic dysregulation in patients; therefore, metabolomics offers a promising tool to study sepsis. It is also known that that in sepsis endothelial cells affecting their function regarding blood clotting and vascular permeability. We integrated metabolomics data from patients admitted to an intensive care unit for sepsis, with commonly collected clinical features of their cases and two measures of endothelial function relevant to blood vessel function, platelet endothelial cell adhesion molecule and soluble thrombomodulin concentrations in plasma. We used least absolute shrinkage and selection operator penalized regression, and pathway enrichment analysis to identify features most able to predict 30-day survival. The features important to sepsis survival include carnitines, and amino acids. Endothelial proteins in plasma also predict 30-day mortality and the levels of these proteins also correlate with a somewhat overlapping set of metabolites. Overall metabolic dysregulation, particularly in endothelial cells, may be a contributory factor to sepsis response. By exploring sepsis metabolomics data in conjunction with clinical features and endothelial proteins we have gained a better understanding of sepsis risk factors.

Abstract
OBJECTIVE The underdiagnosis and inadequate treatment of rheumatoid arthritis (RA) can be attributed to the various clinical manifestations presented by patients. To address this concern, we conducted an extensive review and meta-analysis, focusing on RA-related metabolites. METHODS A comprehensive literature search was conducted in PubMed, the Cochrane Library, Web of Science, and Embase to identify relevant studies published up to October 5, 2022. The quality of the included articles was evaluated and, subsequently, a meta-analysis was conducted using Review Manager software to analyze the association between metabolites and RA. RESULTS Forty nine studies met the inclusion criteria for the systematic review, and six of these studies were meta-analyzed to evaluate the association between 28 reproducible metabolites and RA. The results indicated that, compared to controls, the levels of histidine (RoM = 0.83, 95% CI = 0.79-0.88, I2 = 0%), asparagine (RoM = 0.83, 95% CI = 0.75-0.91, I2 = 0%), methionine (RoM = 0.82, 95% CI = 0.69-0.98, I2 = 85%), and glycine (RoM = 0.81, 95% CI = 0.67-0.97, I2 = 68%) were significantly lower in RA patients, while hypoxanthine levels (RoM = 1.14, 95% CI = 1.09-1.19, I2 = 0%) were significantly higher. CONCLUSION This study identified histidine, methionine, asparagine, hypoxanthine, and glycine as significantly correlated with RA, thus offering the potential for the advancement of biomarker discovery and the elucidation of disease mechanisms in RA.

Abstract
The gut microbiota contributes to the pathophysiology of non-alcoholic fatty liver disease (NAFLD). Histidine is a key energy source for the microbiota, scavenging it from the host. Its role in NAFLD is poorly known. Plasma metabolomics, liver transcriptomics, and fecal metagenomics were performed in three human cohorts coupled with hepatocyte, rodent, and Drosophila models. Machine learning analyses identified plasma histidine as being strongly inversely associated with steatosis and linked to a hepatic transcriptomic signature involved in insulin signaling, inflammation, and trace amine-associated receptor 1. Circulating histidine was inversely associated with Proteobacteria and positively with bacteria lacking the histidine utilization (Hut) system. Histidine supplementation improved NAFLD in different animal models (diet-induced NAFLD in mouse and flies, ob/ob mouse, and ovariectomized rats) and reduced de novo lipogenesis. Fecal microbiota transplantation (FMT) from low-histidine donors and mono-colonization of germ-free flies with Enterobacter cloacae increased triglyceride accumulation and reduced histidine content. The interplay among microbiota, histidine catabolism, and NAFLD opens therapeutic opportunities.

Abstract
Diabetes has been listed as one of the three major diseases that endanger human health. Accurately injecting insulin (Ins) depending on the level of blood glucose (LBG) is the standard treatment, especially controlling LBG in the long-term by a single injection. Herein, the pH-responsive hexa-histidine metal assembly (HmA) encapsulated with enzymes (GOx and CAT) and Ins (HmA@GCI) is engineered as the vehicle for glucose-mediated insulin delivery. HmA not only shows high proteins loading efficiency, but also well retained proteins activity and protect proteins from protease damage. Within HmA, the biocatalytic activities of enzymes and the efficiency of the cascade reaction between GOx and CAT are enhanced, leading to a super response to the change of LBG with insulin release and efficient clearance of harmful byproducts of GOx (H2 O2 ). In the treatment of diabetic mice, HmA@GCI reduces LBG to normal in half an hour and maintains for more than 5 days by a single subcutaneous injection, and nearly 24 days with four consecutive injections. During the test period, no symptoms of hypoglycemia and toxicity to tissues and organs are observed. These results indicate that HmA@GCI is a safe and long-acting hypoglycemic agent with prospective clinical application.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Moxibustion is a traditional medical intervention of traditional Chinese medicine. It refers to the direct or indirect application of ignited moxa wool made of mugwort leaves to acupuncture points or other specific parts of the body for either treating or preventing diseases. Moxibustion has been proven to be effective in treating skin lesions of psoriasis. AIM OF THE STUDY This study was performed to elucidate molecular mechanisms underlying the effects of moxibustion treatment on imiquimod-induced psoriatic mice. MATERIALS AND METHODS We established an imiquimod (IMQ)-induced psoriatic mice (Model) and assessed the effects of moxibustion (Moxi) treatment on skin lesions of psoriatic mice by the PASI scores and expressions of inflammation-related factors relative to normal control mice (NC). We then performed nuclear magnetic resonance (NMR)-based metabolomic analysis on the skin tissues of the NC, Model and Moxi-treated mice to address metabolic differences among the three groups. RESULTS Moxi mice showed reduced PASI scores and decreased expressions of the pro-inflammatory cytokines IL-8, IL-17A and IL-23 relative to Model mice. Compared with the Model group, the NC and Moxi groups shared 9 characteristic metabolites and 4 significantly altered metabolic pathways except for taurine and hypotaurine metabolism uniquely identified in the NC group. To a certain extent, moxibustion treatment improved metabolic disorders of skin lesions of psoriatic mice by decreasing glucose, valine, asparagine, aspartate and alanine-mediated cell proliferation and synthesis of scaffold proteins, alleviating histidine-mediated hyperproliferation of blood vessels, and promoting triacylglycerol decomposition. CONCLUSIONS This study reveals the molecular mechanisms underlying the effects of moxibustion treatment on the skin lesions of psoriasis, potentially improving the clinical efficacy of moxibustion.

Abstract
The continual growth of tumor cells requires considerable nutrient consumption. Methotrexate (MTX) is used to treat certain types of cancer by blocking the DNA and RNA productions through interfering one-carbon metabolism and de novo purine and pyrimidine synthesis. However, treatment of MTX may cause many serious adverse effects, which hamper its clinical application. Herein, the authors synthesize ferrous ions, histidine, and MTX assembled nanoparticles (FHM) to deliver MTX at tumor site and enhance the sensitivity of tumor cells to MTX with histidine catabolism. Furthermore, fasting-mimicking diet (FMD) is applied to intervene in the one-carbon metabolism and enhance the cytotoxicity of MTX. Meanwhile, FMD treatment can significantly augment the cellular uptake and tumor accumulation of FHM nanoparticles. Due to the triple inhibitions of the one-carbon metabolism, the proliferation of tumor cells is strongly disturbed, as which is highly replying on DNA and RNA production. Taken together, a 95% lower dose of MTX adopted in combined therapy significantly inhibits the growth of two types of murine tumors without evident systemic toxicity. This strategy may provide a promising nucleotide metabolism-based nanomedicine for cancer therapy.

Abstract
Artemisinin compounds have shown satisfactory safety records in anti-malarial clinical practice over decades and have revealed value as inexpensive anti-tumor adjuvant chemotherapeutic drugs. However, the rational design and precise preparation of nanomedicines based on the artemisinin drugs are still limited due to their non-aromatic and fragile chemical structure. Herein, a bioinspired coordination-driven self-assembly strategy was developed to manufacture the artemisinin-based nanoprodrug with a significantly increased drug loading efficacy (∼70 wt %) and decreased preparation complexity compared to conventional nanodrugs. The nanoprodrug has suitable size distribution and robust colloidal stability for cancer targeting in vivo. The nanoprodrug was able to quickly disassemble in the tumor microenvironment with weak acidity and a high glutathione concentration, which guarantees a better tumor inhibitory effect than direct administration and fewer side effects on normal tissues in vivo. This work highlights a new strategy to harness a robust, simplified, organic solvent-free, and highly repeatable route for nanoprodrug manufacturing, which may offer opportunities to develop cost-effective, safe, and clinically available nanomedicines.

Abstract
CONTEXT Somapacitan is a long-acting growth hormone (GH) in development for once-weekly treatment of GH deficiency (GHD). Optimal monitoring of insulin-like growth factor-I (IGF-I) levels must account for weekly IGF-I fluctuations following somapacitan administration. OBJECTIVE To develop and assess the reliability of linear models for predicting mean and peak IGF-I levels from samples taken on different days after dosing. DESIGN A pharmacokinetic/pharmacodynamic model was used to simulate IGF-I data in adults and children following weekly somapacitan treatment of GHD. SETTING AND PATIENTS 39 200 IGF-I profiles were simulated with reference to data from 26 adults and 23 children with GHD. INTERVENTION(S) The simulated dose range was 0.02 to 0.12 mg/kg for adults and 0.02 to 0.16 mg/kg for children. Simulated data with >4 average standard deviation score were excluded. MAIN OUTCOME MEASURE(S) Linear models for predicting mean and peak IGF-I levels based on IGF-I samples from different days after somapacitan dose. RESULTS Robust linear relationships were found between IGF-I sampled on any day after somapacitan dose and the weekly mean (R2 > 0.94) and peak (R2 > 0.84). Prediction uncertainties were generally low when predicting mean from samples taken on any day (residual standard deviation [RSD] ≤ 0.36) and peak from samples taken on day 1 to 4 (RSD ≤ 0.34). IGF-I monitoring on day 4 and day 2 after dose provided the most accurate estimate of IGF-I mean (RSD < 0.2) and peak (RSD < 0.1), respectively. CONCLUSIONS Linear models provided a simple and reliable tool to aid optimal monitoring of IGF-I by predicting mean and peak IGF-I levels based on an IGF-I sample following dosing of somapacitan. A short visual summary of our work is available (1).

Abstract
L-histidine (HIS) is an essential amino acid with unique roles in proton buffering, metal ion chelation, scavenging of reactive oxygen and nitrogen species, erythropoiesis, and the histaminergic system. Several HIS-rich proteins (e.g., haemoproteins, HIS-rich glycoproteins, histatins, HIS-rich calcium-binding protein, and filaggrin), HIS-containing dipeptides (particularly carnosine), and methyl- and sulphur-containing derivatives of HIS (3-methylhistidine, 1-methylhistidine, and ergothioneine) have specific functions. The unique chemical properties and physiological functions are the basis of the theoretical rationale to suggest HIS supplementation in a wide range of conditions. Several decades of experience have confirmed the effectiveness of HIS as a component of solutions used for organ preservation and myocardial protection in cardiac surgery. Further studies are needed to elucidate the effects of HIS supplementation on neurological disorders, atopic dermatitis, metabolic syndrome, diabetes, uraemic anaemia, ulcers, inflammatory bowel diseases, malignancies, and muscle performance during strenuous exercise. Signs of toxicity, mutagenic activity, and allergic reactions or peptic ulcers have not been reported, although HIS is a histamine precursor. Of concern should be findings of hepatic enlargement and increases in ammonia and glutamine and of decrease in branched-chain amino acids (valine, leucine, and isoleucine) in blood plasma indicating that HIS supplementation is inappropriate in patients with liver disease.

Abstract
AIM To compare the effects of the four most commonly used preservation solutions on the outcome of liver transplantations. METHODS A systematic literature search was performed using MEDLINE, Scopus, EMBASE and the Cochrane Library databases up to January 31st, 2017. The inclusion criteria were comparative, randomized controlled trials (RCTs) for deceased donor liver (DDL) allografts with adult and pediatric donors using the gold standard University of Wisconsin (UW) solution or histidine-tryptophan-ketoglutarate (HTK), Celsior (CS) and Institut Georges Lopez (IGL-1) solutions. Fifteen RCTs (1830 livers) were included; the primary outcomes were primary non-function (PNF) and one-year post-transplant graft survival (OGS-1). RESULTS All trials were homogenous with respect to donor and recipient characteristics. There was no statistical difference in the incidence of PNF with the use of UW, HTK, CS and IGL-1 (RR = 0.02, 95%CI: 0.01-0.03, P = 0.356). Comparing OGS-1 also failed to reveal any difference between UW, HTK, CS and IGL-1 (RR = 0.80, 95%CI: 0.80-0.80, P = 0.369). Two trials demonstrated higher PNF levels for UW in comparison with the HTK group, and individual studies described higher rates of biliary complications where HTK and CS were used compared to the UW and IGL-1 solutions. However, the meta-analysis of the data did not prove a statistically significant difference: the UW, CS, HTK and IGL-1 solutions were associated with nearly equivalent outcomes. CONCLUSION Alternative solutions for UW yield the same degree of safety and effectiveness for the preservation of DDLs, but further well-designed clinical trials are warranted.

Abstract
Menkes disease is a rare neurodegenerative disorder caused by mutations in ATP7A gene. Deficiency in copper-dependent enzymes results in the unique kinky hair appearance, neurodegeneration, developmental delay, seizures, failure to thrive and other connective tissue or organ abnormalities. Other than biochemical tests, DNA-based diagnosis is now playing an important role. More than two hundred mutations in ATP7A gene were identified. Early copper supplementation can help improve neurological symptoms, but not non-neurological problems. Further molecular studies are needed to identify additional mutation types and to understand the mechanism of pathogenesis. This may help in discovering the possible treatment measures to cure the disease. We present a case with the clinical features and biochemical findings, abnormal brain magnetic resonance imaging as well as the effects of treatment with copper-histidine. Direct sequencing of ATP7A gene revealed a de novo point mutation which resulted in an early stop codon with truncated protein.

Abstract
The degree of 15N incorporation into serum albumin studied by 15N-urea administration in dialyzed patients on a 1.3 g/kg/day protein diet was shown to be almost the same as in non-dialyzed uremic patients on low protein diet, while there was no incorporation in a normal subject. 14.1 g of EAA and histidine was intravenously given in dialyzed patients on the high protein diet and improvements in the level of BUN and anemia were observed. The study with 15N-leucine in a patient proved that about 36% of EAA infused during dialysis was transferred into dialysate. AAD was prescribed by giving 15-20 g of EAA, histidine and tyrosine to patients at each dialysis. The AAD enabled us to give a large amount of EAA asymptomatically in a short time, improving anemia and decreasing the BUN level. 15N-glycine administration in a dialyzed patient proved that 15N incorporation into serum albumin was 3 times greater than his non-dialyzed uremic stage on a low protein diet, and that EAA serum concentrations and non-EAA which had not been added into dialysate were elevated.

Abstract
BACKGROUND Chromium (Cr) is commonly used as a complementary medicine for diabetes mellitus. Several studies suggest that Cr intakes may improve glucose metabolism and decrease oxidative stress. Therefore, we aimed to assess the effects of chromium histidinate (CrHis) supplementation using a range of reliable biomarkers of oxidative damage and histopathological changes in rats with diabetic retinopathy. METHODS Diabetes was induced with streptozotocin [(STZ), 55 mg/kg] by intraperitoneal injection in male Long-Evans rats. Three weeks after STZ injection, rats were divided into four groups, namely, untreated normal controls, normal rats receiving CrHis (110 μg/kg/day); untreated diabetics and diabetics treated with CrHis (110 μg/kg/day) orally for 12 weeks. RESULTS In the untreated diabetic group, levels of serum glucose, glycosylated haemoglobin (HbA1c), total cholesterol (TC) and retina malondialdehyde (MDA) were significantly increased, while expressions of retina insulin, and glucose transporter 1 (GLUT 1) and glucose transporter 3 (GLUT3) and level of serum insulin were decreased. CrHis supplementation was found to reduce the levels of glucose, HbA1c, total cholesterol and MDA and to improve the GLUT1, GLUT3 and insulin expressions in STZ-induced diabetic rats. CrHis prevents the changes in the expressions of GLUT1, GLUT3 and insulin and the level of MDA in the retina tissue, confirming the protective effect of CrHis supplementation against the retinopathy caused by STZ. Histopathologic findings suggest that the CrHis-treated diabetic group had normal retinal tissue appearance compared with the untreated diabetic group. CONCLUSIONS These results verify that CrHis has critical beneficial effects against retinal complications. Although detailed studies are required for the evaluation of the exact mechanism of the ameliorative effects of CrHis against diabetic complications, these preliminary experimental findings demonstrate that CrHis exhibits antidiabetic effects in a rat model of diabetic retinopathy by regulating the glucose metabolism and suppressing retinal tissue damage.

Abstract
Menkes disease is a very rare X-linked copper metabolism disorder that results from an ATP7A gene mutation. With the advent of subcutaneous copper-histidine therapy, the early diagnosis of Menkes disease becomes of utmost importance for patients' prognosis. In the present study, the clinical characteristics of 12 Korean patients with Menkes disease (11 males and 1 female from 11 unrelated families) were described along with the mutation spectrum. Only 2 male patients were diagnosed in the neonatal period, and the other male patients were diagnosed at age 4.3 ± 1.9 months. The presenting signs included depigmented kinky hair, neurologic deficits, and hypotonia. Serum copper and ceruloplasmin levels were markedly decreased. Intracranial vessels were dilated with tortuosity and accompanied by regional cerebral infarctions, even at an early age. Of note, the female patient was diagnosed at age 18 months, during the evaluation for developmental delay, by characteristic MRA findings, biochemical profiles, and genetic evaluation. A total of 11 ATP7A mutations were identified, including five previously unreported mutations. Most mutations were truncated (except 1 missense mutation), including 3 frameshift, 2 nonsense, 3 large deletion, and 2 splice-site variants. The age at commencement of copper-histidine treatment was variable among patients age 7.3 ± 7.5 (0.5-27) months. Despite the treatment, seven patients died before age 5 years, and the remaining patients were severely retarded in neurodevelopment. The poor outcomes of our patients might be related to delayed therapy, but severe ATP7A mutations should be noted as well.

Abstract
Redox active transition metal ions (e.g., iron and copper) have been implicated in the etiology of many oxidative stress-related diseases including also neurodegenerative disorders. Unbound copper can catalyze formation of reactive oxygen species (hydroxyl radicals) via Fenton reaction/Haber–Weiss chemistry and therefore, under physiological conditions, free copper is potentially toxic and very rarely exists inside cells. Copper(II) bound to the aminoacid l-histidine represents a species discovered in blood in the mid 60s and since then extensive research on this complex was carried out. Copper bound to l-histidine represents an exchangeable pool of copper(II) in equilibrium with the most abundant blood plasma protein, human serum albumin. The structure of this complex, in aqueous solution, has been a subject of many studies and reviews, however without convincing success. The significance of the (1:2) copper(II)-l-histidine complex at physiological pH documents its therapeutic applications in the treatment of Menkes disease and more recently in the treatment of infantile hypertrophic cardioencephalomyopathy. While recently the (1:2) Cu(II)-l-His complex has been successfully crystallized and the crystal structure was solved by X-ray diffraction, the structure of the complex in fluid solution at physiological pH is not satisfactorily known. The aim of this paper is to study the (1:2) Cu(II)-l-histidine complex at low temperatures by X-band and S-band EPR spectroscopy and at physiological pH at room temperature by Fourier transform CW-EPR spectroscopy.

Abstract
AIMS/HYPOTHESIS Increased inflammation and oxidative stress are associated with insulin resistance (IR) and metabolic disorders. Serum histidine levels are lower and are negatively associated with inflammation and oxidative stress in obese women. The objective of this study was to evaluate the efficacy of histidine supplementation on IR, inflammation, oxidative stress and metabolic disorders in obese women with the metabolic syndrome (MetS). METHODS A total of 100 obese women aged 33-51 years with BMI ≥ 28 kg/m² and diagnosed with MetS were included following a health examination in the community hospital in this randomised, double-blinded, placebo-controlled trial. Participants were allocated to interventions by an investigator using sequentially numbered sealed envelopes and received 4 g/day histidine (n = 50) or identical placebo (n = 50) for 12 weeks. Participants then attended the same clinic every 2 weeks for scheduled interviews and to count tablets returned. Serum histidine, HOMA-IR, BMI, waist circumference, fat mass, serum NEFA, and variables connected to inflammation and oxidative stress were measured at baseline and 12 weeks. Participants, examining physicians and investigators assessing the outcomes were blinded to group assignment. In addition, the inflammatory mechanisms of histidine were also explored in adipocytes. RESULTS At 12 weeks, a total of 92 participants completed this trail. Compared with the placebo group (n = 47), histidine supplementation significantly decreased HOMA-IR (-1.09 [95% CI -1.49, -0.68]), BMI (-0.86 kg/m² [95% CI -1.55, -0.17]), waist circumference (-2.86 cm [95% CI -3.86, -1.86]), fat mass (-2.71 kg [95% CI -3.69, -1.73]), serum NEFA (-173.26 μmol/l [95% CI -208.57, -137.94]), serum inflammatory cytokines (TNF-α, -3.96 pg/ml [95% CI -5.29, -2.62]; IL-6, -2.15 pg/ml [95% CI -2.52, -1.78]), oxidative stress (superoxide dismutase, 17.84 U/ml [95% CI 15.03, 20.65]; glutathione peroxidase, 13.71 nmol/ml [95% CI 9.65, 17.78]) and increased serum histidine and adiponectin by 18.23 μmol/l [95% CI 11.74, 24.71] and 2.02 ng/ml [95% CI 0.60, 3.44] in histidine supplementation group (n = 45), respectively. There were significant correlations between changes in serum histidine and changes of IR and its risk factors. No side effects were observed during the intervention. In vitro study indicated that histidine suppresses IL6 and TNF mRNA expression and nuclear factor kappa-B (NF-κB) protein production in palmitic acid-induced adipocytes in a dose-dependent manner, and these changes were diminished by an inhibitor of NF-κB. CONCLUSIONS/INTERPRETATION Histidine supplementation could improve IR, reduce BMI, fat mass and NEFA and suppress inflammation and oxidative stress in obese women with MetS; histidine could improve IR through suppressed pro-inflammatory cytokine expression, possibly by the NF-κB pathway, in adipocytes.

Abstract
Mitochondrial glutathione (mGSH) is a critical factor in the cell defense against oxidative and nitrosative stress (ONS), and ONS is a key pathogenic event in hepatic encephalopathy (HE). Acute HE in the thioacetamide (TAA) model caused a 54 % decrease of mGSH content in the rat prefrontal cortex (pfc), but not in the striatum (str), nor did it affect the GSH content in the pfc or str homogenate. In the pfc, treatment with L- histidine (His), which is known to alleviate ONS-related symptoms in HE animals, attenuated the decrease of mGSH, and increased the GSH content in pfc and str homogenates and pfc microdialysates of control animals. His increased the expression of mRNA coding for the GSH synthesizing enzyme, glutamate cysteine ligase (GCL) and decreased that of the GSH-degrading enzyme γ-glutamyltranspeptidase (γGT). The results suggest that the decrease of mGSH may be an important contributing factor to mitochondrial dysfunction in HE, and delineate a new mechanistic aspect of the therapeutic potential of His in HE.

Abstract
The objective of this experiment was to investigate the effects of supplemental chromium picolinate (CrPic) and chromium histidinate (CrHis) on nuclear factor-kappa B (NF-κB p65) and nuclear factor (erythroid-derived 2)-like 2 (Nrf2) signaling pathway in diabetic rat brain. Nondiabetic (n = 45) and diabetic (n = 45) male Wistar rats were either not supplemented or supplemented with CrPic or CrHis via drinking water to consume 8 μg elemental chromium (Cr) per day for 12 weeks. Diabetes was induced by streptozotocin injection (40 mg/kg i.p., for 2 weeks) and maintained by high-fat feeding (40 %). Diabetes was associated with increases in cerebral NF-κB and 4-hydroxynonenal (4-HNE) protein adducts and decreased in cerebral nuclear factor of kappa light polypeptide gene enhancer in B cells inhibitor, alpha (IκBα) and Nrf2 levels. Both Cr chelates were effective to decrease levels of NF-κB and 4-HNE protein adducts and to increase levels of IκBα and Nrf2 in the brain of diabetic rats. However, responses of these increases and decreases were more notable when Cr was supplemented as CrHis than as CrPic. In conclusion, Cr may play a protective role in cerebral antioxidant defense system in diabetic subjects via the Nrf2 pathway by reducing inflammation through NF-κB p65 inhibition. Histidinate form of Cr was superior to picolinate form of Cr in reducing NF-κB expression and increasing Nrf2 expression in the brain of diabetic rats.

Abstract
BACKGROUND The ATP7A gene encodes the ATP7A protein, which is a trans-Golgi network copper transporter expressed in the brain and other organs. Mutations in this gene cause disorders of copper metabolism, such as Menkes disease. Here we describe the novel and unusual mutation (p.T1048I) in the ATP7A gene of a child with Menkes disease. The mutation affects a conserved DKTGT1048 phosphorylation motif that is involved in the catalytic activity of ATP7A. We also describe the clinical course and the response to copper treatment in this patient. CASE PRESENTATION An 11-month-old male Caucasian infant was studied because of hypotonia, ataxia and global developmental delay. The patient presented low levels of serum copper and ceruloplasmin, and was shown to be hemizygous for the p.T1048I mutation in ATP7A. The diagnosis was confirmed when the patient was 18 months old, and treatment with copper-histidinate (Cu-His) was started immediately. The patient showed some neurological improvement and he is currently 8 years old. Because the p.T1048I mutation affects its catalytic site, we expected a complete loss of functional ATP7A and a classical Menkes disease presentation. However, the clinical course of the patient was mild, and he responded to Cu-His treatment, which suggests that this mutation leads to partial conservation of the activity of ATP7A. CONCLUSION This case emphasizes the important correlation between genotype and phenotype in patients with Menkes disease. The prognosis in Menkes disease is associated with early detection, early initiation of treatment and with the preservation of some ATP7A activity, which is necessary for Cu-His treatment response. The description of this new mutation and the response of the patient to Cu-His treatment will contribute to the growing body of knowledge about treatment response in Menkes disease.

Abstract
Menkes disease is a lethal X-linked recessive neurodegenerative disorder of copper transport caused by mutations in ATP7A, which encodes a copper-transporting ATPase. Early postnatal treatment with copper injections often improves clinical outcomes in affected infants. While Menkes disease newborns appear normal neurologically, analyses of fetal tissues including placenta indicate abnormal copper distribution and suggest a prenatal onset of the metal transport defect. In an affected fetus whose parents found termination unacceptable and who understood the associated risks, we began in utero copper histidine treatment at 31.5 weeks gestational age. Copper histidine (900 μg per dose) was administered directly to the fetus by intramuscular injection (fetal quadriceps or gluteus) under ultrasound guidance. Percutaneous umbilical blood sampling enabled serial measurement of fetal copper and ceruloplasmin levels that were used to guide therapy over a four-week period. Fetal copper levels rose from 17 μg/dL prior to treatment to 45 μg/dL, and ceruloplasmin levels from 39 mg/L to 122 mg/L. After pulmonary maturity was confirmed biochemically, the baby was delivered at 35.5 weeks and daily copper histidine therapy (250 μg sc b.i.d.) was begun. Despite this very early intervention with copper, the infant showed hypotonia, developmental delay, and electroencephalographic abnormalities and died of respiratory failure at 5.5 months of age. The patient's ATP7A mutation (Q724H), which severely disrupted mRNA splicing, resulted in complete absence of ATP7A protein on Western blots. These investigations suggest that prenatally initiated copper replacement is inadequate to correct Menkes disease caused by severe loss-of-function mutations, and that postnatal ATP7A gene addition represents a rational approach in such circumstances.

Abstract
Uterine transplantation may be a possible treatment option in the future for absolute uterine infertility. The tolerance of human uterine tissue to cold ischemic preservation is one of the issues that need to be resolved. The objective of this study was to assess the morphological changes in human uterine tissue after cold ischemic preservation in a transplant solution. Small tissue samples of human uteri were subjected to cold ischemia (2-8 degrees C for up to 48 hours) in Celsior transplant solution. Histological analysis by light and electron microscopy was used to assess evidence of cold ischemic injury. Histological examination did not show any major changes of the uterine tissue after 48-hour cold preservation; whereas, electron microscopy after 24 hours confirmed unchanged structural integrity of the uterine myoendometrium. The human uterus is morphologically resistant toward cold ischemia in Celsior preservation solution for up to 24 hours and may be suitable for transplantation purposes.

Abstract
Surgical resection of brain tissue is associated with tissue damage at the resection margin. Studies of ischemic brain injury in rodents have shown that administration of L-histidine and thioperamide reduces ischemic tissue loss, in part by inhibition of apoptotic cell death. In this study we tested administration of L-histidine and thioperamide in surgical brain injury in mice. Mice were randomized to one of three groups: Sham surgery (n=18), surgical brain injury without treatment (SBI) (n=33), and surgical brain injury with combined l-histidine and thioperamide treatment (SBI+H) (n=29). Surgical brain injury was induced via right frontal craniotomy with resection of the right frontal lobe. L-histidine (1000 mg/kg) and thioperamide (5 mg/kg) were administered to the SBI+H group immediately following surgical resection. Postoperative assessment included neurobehavioral scores, Evans blue measurement of blood-brain barrier breakdown, brain water content, Nissl histology, and immunohistochemistry for IgG and cleaved caspase 3. Postoperative findings included equivalent neurobehavioral outcomes at 24 and 72 h in the SBI and SBI+H groups, similar histological outcomes between SBI and SBI+H, and similar qualitative staining for cleaved caspase 3. SBI+H had increased BBB breakdown on Evans blue analysis and a trend towards increased brain edema which was significant at 72 h. We conclude that combined treatment with l-histidine and thioperamide leads to increased BBB breakdown and brain edema in surgical brain injury.

Abstract
Inflammation is a crucial factor in the development of ischemia-induced brain injury. Since facilitation of central histaminergic activity ameliorates reperfusion injury, effects of postischemic administration of L-histidine, a precursor of histamine, and thioperamide, a histamine H3 receptor antagonist, on inflammatory cell infiltration were evaluated in a rat model of transient occlusion of the middle cerebral artery. After reperfusion for 12, 24, or 72 h following 2 h of occlusion, brain slices were immunohistochemically stained with antibodies against myeloperoxidase and CD68, which were markers of polymorphonuclear leukocytes and macrophages/microglia, respectively. After reperfusion for 12-24 h, the number of neutrophils on the ischemic side increased markedly, whereas the increase was not observed on the contralateral side. Administration of L-histidine (1000 mg/kg x 2, i.p.), immediately and 6 h after reperfusion, reduced the number of neutrophils to 52%. Simultaneous administration of thioperamide (5 mg/kg, s.c.) further decreased the number of neutrophils to 32%. Likewise, the ischemia induced increase in the number of CD68-positive cells after 24 h was suppressed by L-histidine injections. The L-histidine administration decreased the number of CD4+ T lymphocytes on both ischemic and contralateral sides after 12 h, and concurrent administration of thioperamide prolonged the effect. Although administration of mepyramine (3 nmol, i.c.v.) did not affect suppression of leukocyte infiltration, ranitidine tended to reverse the effect of L-histidine. These data suggest that enhancement of central histaminergic activity suppresses inflammatory cell recruitment after ischemic events through histamine H2 receptors, which may be a mechanism underlying the protective effect of L-histidine.

Abstract
An increase in the histamine concentration in the brain has been demonstrated to provide protective effects against ischemia/reperfusion brain injury. Since hypothermia and barbiturates are also regarded to protect ischemic brains, effects of postischemic treatments were compared in gerbils between mild hypothermia and intraperitoneal administration of L-histidine, a precursor of histamine. Furthermore, effects of thioperamide, a histamine H(3) receptor antagonist, were evaluated in histidine-treated gerbils after 60 days. Transient forebrain ischemia for 4 min at 37 degrees C provoked severe neuronal damage in the hippocampal CA1 pyramidal cells after 7 days. Postischemic hypothermia (33 degrees C) for 3 h under pentobarbital anesthesia alleviated neuronal death, and the number of preserved neurons was 77+/-56/mm (mean+/-S.D., n=14). The effect of L-histidine injected three times, immediately, 6 h, and 24 h after reperfusion (1,000 mg/kg, i.p., each), was more prominent than that of hypothermia, and the number of preserved neurons was 142+/-55/mm (n=14). When the histologic outcome was evaluated after 60 days, most neurons were damaged in both the hypothermic and histidine groups. The improvement of the histologic outcome was observed even after 60 days in animals injected with thioperamide, immediately and 6 h after reperfusion (5 mg/kg, s.c., each), with three injections of l-histidine. The number of preserved neurons was 133+/-88/mm (n=10), while that in the hypothermic group was 7+/-15 (n=10). Activation of the central histaminergic system provides beneficial effects against cerebral ischemia.

Abstract
We examined the renoprotective effects of l-carnosine (beta-alanyl-l-histidine) on ischemia/reperfusion (I/R)-induced acute renal failure (ARF) in rats. Ischemic ARF was induced by occlusion of the left renal artery and vein for 45 min followed by reperfusion, 2 weeks after contralateral nephrectomy. In vehicle (0.9% saline)-treated rats, renal sympathetic nerve activity (RSNA) was significantly augmented during the renal ischemia, and renal function was markedly decreased at 24 h after reperfusion. Intracerebroventricular injection of l-carnosine (1.5 and 5 pmol/rat) to ischemic ARF rats dose-dependently suppressed the augmented RSNA during ischemia and the renal injury at 24 h after reperfusion. N-alpha-Acetyl-l-carnosine [N-acetyl-beta-alanyl-l-histidine; 5 pmol/rat intracerebroventricular (i.c.v.)], which is resistant to enzymatic hydrolysis by carnosinase, did not affect the renal injury, and l-histidine (5 pmol/rat i.c.v.), a metabolite cleaved from l-carnosine by carnosinase, ameliorated the I/R-induced renal injury. Furthermore, a selective histamine H(3) receptor antagonist, thioperamide (30 nmol/rat i.c.v.) eliminated the preventing effects by l-carnosine (15 nmol/rat intravenously) on ischemic ARF. In contrast, a selective H(3) receptor agonist, R-alpha-methylhistamine (5 pmol/rat i.c.v.), prevented the I/R-induced renal injury as well as l-carnosine (5 pmol/rat) did. These results indicate that l-carnosine prevents the development of I/R-induced renal injury, and the effect is accompanied by suppressing the enhanced RSNA during ischemia. In addition, the present findings suggest that the renoprotective effect of l-carnosine on ischemic ARF is induced by its conversion to l-histidine and l-histamine and is mediated through the activation of histamine H(3) receptors in the central nervous system.

Abstract
Cerebral ischemia induces excess release of glutamate and an increase in the intracellular Ca(2+) concentration in neurons, which provokes enzymatic process leading to irreversible neuronal injury. Histamine plays a role as a neurotransmitter in the mammalian brain, and histamine release from nerve endings is enhanced in ischemia by facilitation of histaminergic activity. Dissimilar to ischemia-induced release of glutamate, histamine release is gradual and long lasting. The enhancement may contribute to neuroprotection against ischemic damage, because suppression of histaminergic activity aggravates the histologic outcome caused by ischemia. Preischemic administration of histamine (i.c.v.) suppresses ischemic release of glutamate and ameliorates neuronal damage, whereas blockade of central histamine H(2) receptors aggravates ischemic injury. These suggest that histamine provides beneficial effects against ischemic damage through histamine H(2) receptors, when administered before induction of ischemia. Postischemic loading with histidine, a precursor of histamine, alleviates both brain infarction and delayed neuronal death. Since the alleviation is abolished by blockade of central histamine H(2) receptors, facilitation of central histamine H(2) action caused by histidine may prevent reperfusion injury after ischemic events. Because the ischemia-induced increase in the glutamate level rapidly resumes after reperfusion of cerebral blood flow, beneficial effects caused by postischemic loading with histidine may be due to other mechanisms besides suppression of excitatory neurotransmitter release. Anti-inflammatory action by histamine H(2) receptor stimulation is a likely mechanism responsible for the improvement.

Abstract
Our aim was to investigate whether the addition of glyceryl trinitrate (GTN), a source of nitric oxide, and/or cariporide, a Na/H exchange inhibitor, to a commercial preservation solution (Celsior) improved and extended cardiac preservation. After baseline indices of cardiac function (aortic flow, coronary flow, heart rate, cardiac output) were measured in an isolated working rat heart model, hearts were arrested and stored at 2-3 degrees C for 6 or 10 h in Celsior solution alone, Celsior supplemented with either 0.1 mg/mL GTN or 10 microM cariporide or both. After storage, functional measurements were repeated and recovery of each parameter was expressed as a percentage of its pre-storage baseline. After 6 h storage, recovery of cardiac function was significantly better in hearts stored in GTN- or cariporide-supplemented Celsior solution compared with Celsior solution alone. The beneficial effect of GTN was significantly abrogated in hearts perfused with glibenclamide prior to storage. Significant recovery of cardiac function after 10 h storage was only observed in hearts stored in Celsior solution supplemented with both GTN and cariporide. Combined supplementation with GTN and cariporide extends the safe period of storage of the rat heart and may be a useful approach to enhancing preservation of the donor heart.

Abstract
We report on metabolic changes in the brain of a boy with Menkes disease. He was treated with parenteral copper (Cu)-histidine supplementation, from 5 months of age, and assessed with proton magnetic resonance spectroscopy ((1)H-MRS). The single-voxel (1)H-MRS before treatment revealed an accumulation of lactate and a reduced N-acetyl aspartate (NAA)/total creatine (tCr) ratio with a z-score of -3.0. During treatment, the lactate signal faded away, whereas the NAA signal gradually increased to a z-score of -1.5 at 120 days of treatment. The choline/tCr ratio did not deviate much initially (z-score +0.5), but the ratio increased markedly during treatment (z-score +4.8). Consequently, the Cu-histidine therapy initiated after the critical period still improved the neuronal metabolism, suggesting that some Cu was delivered to neurons. Nevertheless, the brain atrophy, impaired myelination, and severe neurological symptoms were not ameliorated.

Abstract
BACKGROUND Because of the antisecretory potential of L-histidine in the intestinal tract, its antidiarrheal effects were determined in cholera. METHODS In a double-blind trial of 126 adult male patients with cholera, L-histidine (2.5 g/L) was mixed with a rice-based oral rehydration solution (ORS) and administered to 62 patients; 64 patients received the same ORS without L-histidine. All patients received ciprofloxacin at a dosage of 500 mg every 12 h for 72 h. Fluid output (of stool, urine, and vomit) and intake (of ORS, water, and intravenous fluid) were determined every 8 h for 72 h. RESULTS Administration of ORS with L-histidine significantly (P<.05) reduced the frequency of stool output during 32-64 h after initiation of ORS treatment, compared with that in patients given ORS without L-histidine ([all data are means+/-SD] 32-48 h, 11.5+/-6.9 mL/kg vs. 18.8+/-16.0 mL/kg; 40-48 h, 6.7+/-4.4 mL/kg vs. 11.5+/-9.7 mL/kg; and 56-64 h, 6.3+/-5.8 mL/kg vs. 7.8+/-4.1 mL/kg). An overall reduction of 22% in the volume of stool was observed in patients given ORS without L-histidine. The amount of required unscheduled intravenous fluid was lower in patients given ORS with L-histidine, compared with that in patients given ORS without L-histidine (0-24 h, 82.5+/-44.4 mL/kg vs. 158.6+/-72.2 mL/kg [P<.01]; and 24-48 h, 41.6+/-40.4 mL/kg vs. 52.5+/-22.1 mL/kg [P>.05]). Administration of ORS with L-histidine also significantly reduced (P<.05) the intake of ORS and the duration of illness. No adverse effects were observed in these patients. CONCLUSIONS L-histidine reduces the weight of stool and the frequency of stool output in cholera and could be a useful and safe adjunct treatment that will increase the success rate of ORS and antibiotic therapy in cholera.

Abstract
Menkes' Kinky Hair Syndrom is a rare, X-linked recessive multisystemic lethal disorder of copper metabolism. Male infants who are affected usually die at the age of 2-3 years. If the disease is diagnosed early, patients profit from subcutaneously administered copper salts. We describe the preparation and stability of a copper-histidin solution. This solution has some advantages in terms of stability over the solutions described in earlier publications. This is a great advantage for the patients and their parents, because an ambulatory care or a home care of this patients is possible now.

Abstract
Inflammatory reactions play an important role in ischemia-reperfusion injury in the brain. Since histamine H(2) action suppresses inflammatory reactions, effects of postischemic loading with histidine, a precursor of histamine, were examined. Focal cerebral ischemia for 15 min was provoked by transient occlusion of the right middle cerebral artery in rats, and delayed neuronal death were evaluated in striatal neurons after 7 days. Histidine was administered four times, immediately, 6, 24, and 48 h after reperfusion of blood flow (1000 mg/kg, i.p., each time). To examine the role of histaminergic action on changes in histologic outcome, effects of mepyramine (3 nmol, i.c.v.), an H(1) antagonist, and ranitidine (30 nmol, i.c.v.), an H(2) antagonist, were evaluated in histidine-treated rats. Transient ischemia for 15 min provoked severe neuronal damage in the saline-injected control group, and the number of striatal neurons decreased to 21% of that on the contralateral side. Administration of histidine alleviated ischemic neuronal damage, and the number of preserved neurons was 76% of that on the contralateral side. Simultaneous administration of mepyramine with histidine did not affect the histologic outcome. However, administration of ranitidine abolished the alleviation by histidine. These findings indicate that the elevation of histamine H(2) receptor stimulation by massive administration of histidine suppresses reperfusion injury in the brain.

Abstract
Mutations in Sco2, a protein involved in copper trafficking to the terminal enzyme of the respiratory chain, cytochrome c oxidase, results in infantile hypertrophic cardioencephalomyopathy. We have recently shown that copper-histidine (Cu-his) supplementation of Sco2-deficient myoblasts rescues COX activity in vitro. Here, we report a patient with SCO 2 mutations and with resolution of severe hypertrophic cardiomyopathy. Weighing up the evidence, the most likely explanation for the improved cardiac function in this patient was the subcutaneous application of Cu-his.

Abstract
Primary dysfunction (PDF) still occurs after orthotopic liver transplantation (OLT). Celsior solution (CS) might offer some advantages over the conventional University of Wisconsin (UW) solution for organ preservation, but to date, this has not been prospectively evaluated in the context of OLT. In this prospective, randomized, multicenter, pilot study, 215 potential liver donors were enrolled and randomized. In 42 cases, the livers were unsuitable for transplantation; therefore, 173 randomized livers ultimately were implanted after perfusion and cold preservation with CS (n = 83) or UW solution (n = 90). In accord with the indications of the CS manufacturing company, total CS infusion volume was 90 mL/kg, greater than that of UW solution (60 mL/kg). The main aim of the study is to compare the prevalence of PDF between the two groups. Donor and recipient variables were similar in the two groups. Episodes of PDF were numerically lower in the CS (2.4%) than UW group (7.8%), but the difference was not statistically significant. There was a trend toward a lesser need for early re-OLT (<30 days) in the CS group (P =.0507), but again, no statistically significant difference emerged. Overall and time-differentiated postoperative deaths also were similar. One-year actuarial patient (UW, 89% v CS, 87%) and graft (UW, 83% v CS, 85%) survival rates were similar. In conclusion, CS was similar to UW solution as a preservation solution in the clinical setting of OLT at the infusion volumes described, although some theoretical advantages of CS composition suggest that CS might prove a valid alternative to UW preservation solution in multiorgan harvesting, including the liver. A study on a larger patient basis is needed.

Abstract
The amino acid histidine is metabolized to glutamic acid in mammalian tissue. Formiminoglutamic acid (FIGLU) is an intermediary in this reaction, and tetrahydrofolic acid is the coenzyme that converts it to glutamic acid. A test for folate deficiency concerns the measurement of urinary FIGLU excretion after a histidine load. It was observed that folate-deficient individuals receiving the histidine for the FIGLU test made hematological response that alleviated the anemia associated with this deficiency. This was unusual in that a biochemical test to determine the deficiency results in a beneficial effect for one aspect of the deficiency. The studies reported in this paper give a metabolic explanation for this phenomenon. Urine was collected for 24 hr from 25 folate-deficient subjects, 10 vitamin B(12)-deficient subjects, and 15 normal controls. Urinary excretion of histidine was a mean of 203 mg with a range of 130-360 mg for the folate-deficient subjects; 51.5 mg with a range of 30-76.6 mg for normal subjects; and 60.0 mg with a range of 32.3-93.0 mg for the vitamin B(12)-deficient subjects. All the folate-deficient subjects subsequently made a hematological response to the histidine administered for the FIGLU test. No hematological response was observed in the vitamin B(12)-deficient individuals. When folic acid was given to folate-deficient subjects who received no histidine, urinary histidine levels returned to normal levels rapidly and this was followed by a hematological response. Others have shown that volunteers fed a histidine-free diet developed anemia. In normal subjects, histidine is excreted much more in the urine than other essential amino acids are. Hemoglobin protein contains 10% histidine. Under normal conditions, dietary histidine can supply sufficient histidine to prevent anemia. When the dietary intake is diminished or the urinary excretion is greatly increased, anemia results. It is concluded that folate deficiency causes histidine depletion through increased urinary excretion of this amino acid. Feeding histidine replenishes tissue levels of histidine, resulting in hemoglobin regeneration. Folic acid administration results in return of histidine to normal urinary levels. Thus, a combination of folic acid histidine would be beneficial for folate deficient individuals.

Abstract
OBJECTIVE P-113, a 12 amino acid histatin-based peptide, was evaluated in a mouthrinse formulation for safety and efficacy in a phase 2 multi-center clinical study. METHOD 294 healthy subjects abstained from oral hygiene procedures and self-administered either 0.01% P-113, 0.03% P-113 or placebo mouthrinse formulations twice daily over a 4-week treatment period. During this time, the safety, anti-gingivitis, and anti-plaque effects of P-113 were evaluated. RESULTS There was a significant reduction in the change from baseline to Day 22 in bleeding on probing in the 0.01% P-113 treatment group of the intent to treat population (p=0.049). Non-significant trends in the reduction of the other parameters were observed in this population (p> or =0.159). A sub-group of subjects which developed significant levels of disease within the four-week timeframe of the study was identified based on baseline gingival index scores > or =0.75. Significant findings were observed for bleeding on probing, gingival index and plaque index within this population (p<0.05). There were no treatment-related adverse events, and there were no adverse shifts in supragingival microflora during the study. Significant amounts of the peptide were retained in the oral cavity following rinsing. CONCLUSION These data suggest that P-113 mouthrinse is safe and reduces the development of gingival bleeding, gingivitis and plaque in the human experimental gingivitis model.

Abstract
Ascorbic acid and L-histidine were investigated as antioxidant therapies for acute mammary inflammation. Mastitis was induced in eight nonpregnant Holstein cows by intramammary infusion of endotoxin. Treatments were administered in a 4 x 4 Latin square crossover design with 1-wk periods between challenges with endotoxin. Four individual treatments, control, ascorbic acid only, L-histidine only, and ascorbic acid plus L-histidine, were applied. Two doses of 25 g of ascorbic acid administered intravenously at 3- and 5-h postendotoxin challenge increased milk production recovery (9% higher, P < 0.02) and tended to reduce the extent of rumen stasis. Two doses of 25 g of L-histidine similarly administered decreased plasma antioxidant activities 5.5% (P < 0.05). However, ascorbic acid and L-histidine had no effects on rectal temperature, heart rate, respiratory rate, and dry matter intake. The data suggested that ascorbic acid provided some potential benefit for recovery from acute mammary inflammation in dairy cattle.

Abstract
OBJECTIVE P-113, a 12 amino acid histatin-based peptide, was evaluated in a mouthrinse formulation for safety, prevention of the development of experimental gingivitis, and for its effects on periodontal flora. METHOD 159 periodontally healthy subjects abstained from oral hygiene procedures and self-administered either 0.005%, 0.01%, 0.05% P-113 or placebo mouthrinse formulations twice daily over a four week treatment period. During this time, the safety, anti-plaque, and anti-gingivitis effects of P-113 were evaluated. RESULTS There was a significant reduction in plaque (p=0.046) and a reduction in gingivitis (p=0.086) for subjects using 0.01% P-113 mouthrinse. Significantly more subjects in the 0.01% and 0.05% treatment groups showed a small increase in plaque index of <0.25 as compared to the placebo group (p<0.05). Similar trends were noted for changes in the % of sites with bleeding on probing in the 0.01% P-113 group. There were no treatment-related adverse events, and there were no adverse shifts in supragingival microflora during the study. CONCLUSION These data suggest that P-113 mouthrinse is safe and reduces plaque, gingivitis and gingival bleeding in the human experimental gingivitis model.

Abstract
Menkes disease (MD) is an X-linked recessive disorder of copper metabolism, characterized in its untreated state by progressive disorders of multiple systems, especially the central nervous system (CNS) and connective tissue, and death by 3 years of age. Recently, therapy with copper-histidine has modified the severity of MD and permitted survival into adolescence. Clinical response has been greater for the neurological abnormalities than for the connective tissue abnormalities. In this report, we describe the postmortem pathology of one individual who had received copper-histidine therapy and died at age 10; we believe this to be the first such pathological report. The postmortem examination demonstrated significant pathology of mesenchymal tissues, including skeletal abnormalities, vascular degeneration, and bladder diverticula. The CNS, by contrast, showed minimal pathology. The phenotype was more consistent with occipital horn syndrome, a milder allelic disorder of copper metabolism, than with classic MD. The differential sensitivity of CNS and mesenchymal tissues to copper-histidine therapy may result from heterogeneity in the response of different copper-dependent enzymes.

Abstract
Clostridium difficile toxin A displays both cytotoxic and enterotoxic activities. It has recently been demonstrated that toxin A exerts its cytotoxic effect by the glucosylation of the small GTP-binding proteins of the Rho family. Diethyl pyrocarbonate, at pH 7.0, was used to chemically modify exposed histidine residues on toxin A. Modification of toxin A with diethyl pyrocarbonate abolished both its cytotoxic activity and the ability of the toxin to bind Zn-Sepharose gel. Treatment of toxin A with [(14)C]-diethyl pyrocarbonate revealed concentration dependent labelling of histidine residues on the toxin molecules. The effects of diethyl pyrocarbonate could be reversed by hydroxylamine treatment. These data suggest the modified histidine residues on toxin A are critical to its cytotoxic activity. Histidine modification had no effect on the glucosyl transferase enzyme activity of toxin A. However, modification abolished the 'cold' binding of toxin to bovine thyroglobulin in an ELISA and reduced ligand binding activity in a rabbit erythrocyte haemagglutination assay. The data suggest that the histidine residues may be crucial to the receptor-binding activity of toxin A. Exposed histidines on toxin A are available for zinc chelation, and these have been exploited in the development of a novel purification protocol for toxin A using zinc-chelating chromatography.

Abstract
Epileptic seizures are a common feature in Menkes disease, an X-linked genetic disorder of copper metabolism. Details of type of seizures are rarely reported. We report the evolution of infantile spasms in two patients with Menkes disease and the relation with subcutaneous administration of copper-histidine.
