syriacus extracts inhibited the growth of B melitensis The MIC5

syriacus extracts inhibited the growth of B. melitensis. The MIC50 values of O. syriacum and T. syriacus aqueous extracts were 3.125 µl/ml and 6.25 µl/ml, respectively. Reuben et al.40 found that the MIC and MBC often had comparable or close values, concluding that the essential oils of O. syriacum and T. syriacus possessed bactericidal effect on B. melitensis. Darabpour et al. found that the methanolic extract of Peganum harmala L seed exhibited a broad antibacterial activity against B. melitensis even at lowest concentration (50 mg/ml).41 Inhibitors,research,lifescience,medical Shapouri and Rahnema reported the MIC of aqueous hops extract for B. abortus 544

and B. melitensis 16M, as 0.625 mg/ml, whereas that of acetonic and ethanolic extracts being 0.05 mg/ml.42 Motamedi and his colleagues studied the effect of plant extract-antibiotic combination against

B. melitensis, and observed a synergitistic activity in the combination of Oliveria decumbens extracts and doxycycline. In our in vitro study of T. syriacus aqueous extract of essential oil, a good additive activity against two B. melitensis Inhibitors,research,lifescience,medical isolates was demonstrated when it was used in combination with levofloxacin. Conclusion Our study showed that O. syriacum and T. syriacus essential oils were most effective against B. melitensis. This could provide a potential source of new antibacterial agents which is worthy of clinical trials. In addition, doxycycline, levofloxacin and ofloxacin were the most effective antibiotics. Moreover, Inhibitors,research,lifescience,medical levofloxacin

and Thymus syriacus essential oil combination was more effective than either antibiotic or the essential oil alone. Further and more specific studies, in vivo, are recommended to determine the efficacy of these essential oils in the treatment of brucellosis infections.

Background: Lead is a toxic element Inhibitors,research,lifescience,medical which causes acute, subacute or chronic poisoning through environmental and occupational exposure. The aim of this study was to investigate clinical and laboratory abnormalities of chronic lead poisoning among workers of a car battery industry. Methods: Questionnaires and forms were designed and used to record demographic why data, past medical histories and clinical manifestations of lead poisoning. Blood samples were taken to determine biochemical (using Auto Analyzer; Model BT3000) and hematologic (using Cell Counter Sysmex; Model KX21N) parameters. An selleck kinase inhibitor atomic absorption spectrometer (Perkin-Elmer, Model 3030, USA) was used to determine lead concentration in blood and urine by heated graphite atomization technique. Results: A total of 112 men mean age 28.78±5.17 years, who worked in a car battery industry were recruited in the present study. The most common signs/symptoms of lead poisoning included increased excitability 41.9%, arthralgia 41.0%, fatigue 40.1%, dental grey discoloration 44.

During the 70s, a nosological revival set in, heralded by the publication of Feighner’s Research Diagnostic Criteria (1972) ,2 which reached its pinnacle in 1980 with the publication of the 3rd edition of the Diagnostic and Statistical .Manual of Mental Disorders (DSM-III).The taxonomy of DSM-IIT was constructed on nosological

principles and defined a Inhibitors,research,lifescience,medical large number of discrete disorders based on symptomatological and some nonsymptomatological criteria, such as duration, severity, and course. The DSM system was based on consensus opinion and reviews of the literature rather than on systematic empirical studies. This was inevitable inasmuch as doing otherwise would have set back for years the publication of the first operationalized and standardized psychiatric taxonomy. Since DSM-III there have been two revisions (DSM-III-R and Inhibitors,research,lifescience,medical DSM-IV), yet without confirmation of the numerous diagnostic constructs that had been introduced. Validating studies were unable to keep pace with the rate of publication of new versions, and the field studies carried out toward this end were simply insufficient. The International

Classification of Diseases (I CD), drawn up by the World Health Organization (WHO), Inhibitors,research,lifescience,medical followed a similar fate. The 10th edition of the ICD (ICD-10), completed in the 80s, operationalized the diagnostic criteria for mental diseases and formulated decision trees to arrive at particular diagnoses. ICD-10 was likewise based on expert opinion and reviews of the literature. Experts from some 40 countries were involved in the project. A steering committee coordinated the activities

of the different working groups, and the revision was finally put before and approved by a combined WHO/Adamha conference in Inhibitors,research,lifescience,medical 1985. For both DSM-IV and ICD-10, primary care versions are available, in which diagnostic criteria are simplified, several subtypes eliminated, Inhibitors,research,lifescience,medical and emphasis is placed on conditions encountered in everyday practice. Only in the case of ICD-1 0 was a version for Selleckchem Tanespimycin researchers published, in which diagnostic criteria were defined in greater detail (DCR10). Like the DSM, the ICD system has a multiaxial structure, but the axes differ in both publications. 4-Aminobutyrate aminotransferase Sustained efforts are being made to homogenize the two classification systems where possible. DSM is far more used in psychiatric research than the ICD system, which explains why the following analysis is DSM-oriented. Nevertheless, most of the considerations presented here are applicable to the ICD taxonomy as well. Psychiatric diagnosing; past and present Some 40 years ago, the framework of psychiatric diagnoses was profoundly different from the way it looks today. On the one hand we gained, on the other hand we lost. Then, psychiatric diagnoses were chaotic, in that standardized and generally accepted diagnostic criteria were lacking.

23 Myocarditis and cardiomyopathy were also associated with chlor

23 Myocarditis and cardiomyopathy were also associated with chlorpromazine, lithium, fluphenazine, risperidone, and haloperidol, but these associations need to be further investigated in order to establish whether they are causal. Figure 4. Acute myocarditis 8 days after clozapine treatment initiation: histopathological pattern. Cardiac tissue of a 18-year-old woman

with myocytolysis, diffuse eosinophilic and lymphocytic infiltrates. The etiology seems to be clearly of immunological or hypersensitivity … Discussion The above information indicates that Inhibitors,research,lifescience,medical ECG monitoring should be performed during hospitalization and ambulatory treatment, at least when multiple psychotropic drug regimens, methadone maintenance treatment, and other predisposing factors for QT prolongation are present at admission. We particularly recommend Inhibitors,research,lifescience,medical regular cardiac and ECG monitoring in patients receiving clozapine, high-dosage antipsychotics, tricyclic antidepressants, drug regimens with potential interactions, or in clinical situations recognized as promoters of QT prolongation. Further electrocardiographic studies in psychiatric patients, systematic recording of case reports, and data mining in pharmaco

vigilance systems will help establish the magnitude of cardiac adverse Inhibitors,research,lifescience,medical reactions to psychotropic drugs.
Depression is considered to be an Independent risk factor for cardiovascular

mortality and morbidity in patients with Ischemic heart disease (IHD).1,2The risk of cardiovascular disease is higher in Individuals suffering from depression,3 as is the risk of ischemic stroke.4 Among newly Inhibitors,research,lifescience,medical diagnosed patients with coronary heart disease, approximately one in five patients suffers from major depression, with a similar prevalence in patients recovering from acute myocardial infarction.5,6 The proposed mechanisms are either spurious, le, that depression predicts, but is not causally related to, cardiovascular heart disease morbidity and mortality Inhibitors,research,lifescience,medical (antidepressant cardiotoxicity, association with cardiac risk factors, sedentary lifestyle), or imply that depression may inhibitors directly influence the course of cardiac heart disease (nonadherence to cardiac treatment and regimens, dysregulation of autonomic, neuroendocrine, and serotonergic systems).7 Serotonergic neurotransmission dysfunction has been investigated and observed in major depression.8,9 Various Thymidine kinase findings support the hypothesis that alterations in serotonergic neurons play a role in the pathophysiology of depression,10 and most antidepressants have a direct influence on serotonin (5-HT) transmission and levels. 5-HT is usually a vasodilator, becoming a vasoconstrictor when the endothelium is damaged.11 It is also involved in platelet aggregation. It is taken up from plasma and stored in platelet granules.

More recently, it has been proposed that aligned scaffolds made of natural or synthetic materials, could improve

axonal growth and facilitate the correct reattachment between the stumps inside the tube (Verdú et al. 2002; Kijeńska et al. 2012; Wang et al. 2012). Such scaffolds would also allow an increase in the gap between the proximal and distal stumps, which is one of the main advantages of the autograft repair approach. The use of functional molecules that may have autoassembling characteristics can facilitate the construction of organized Inhibitors,research,lifescience,medical scaffolds. Thus, the architecture of the collagen fibers plays a critical role in determining the biomechanical behavior of the extracellular matrix, and the alignment and GDC-0994 in vivo organization of its fibers depend on the function of the tissue in which they are found. Therefore, the collagen fibers of the extracellular matrix derived from tendons and ligaments are highly aligned to the long axis of the whole structure (Badylak et al. 2009). Nevertheless, the fibers and/or bundles of collagen tendons are not arranged in a flat structure, and Inhibitors,research,lifescience,medical the pattern of waves reflects the helical organization of the collagen fibers/bundles. Thus, the orientation of the tendon fibers can be considered as a complex structure with supramolecular organization (Vidal 2003; Vidal and Mello 2010). Axial sections of bovine tendons

treated with acetic acid Inhibitors,research,lifescience,medical and examined under polarized light support the supra-organization of helical bundles of collagen in these tendons, and a similar organization has been described in rat tendons (Vidal 2003). The organization Inhibitors,research,lifescience,medical and state of molecular aggregation of a biological implant are important factors that provide a suitable environment for axonal guidance and regeneration, and a naturally oriented protein can facilitate axonal growth and be degraded more efficiently (Fields et al.

1989; Labrador et al. Inhibitors,research,lifescience,medical 1998; Ceballos et al. 1999). In contrast, collagen, when subjected to different treatments, does not reproduce the helically organized pattern of fibers (Oliveira et al. 2005). The present authors previously showed that Schwann cells cultured on a naturally aligned collagen substrate expressed higher levels of the low-affinity receptor for neurotrophins (p75NTR) Thymidine kinase and for S100 (Pierucci et al. 2009). Also, cell orientation was enhanced when the cultures were established in the organized collagen substrate. It is possible that such a scaffold may provide a better support for regenerating axons if inserted into the gap between the nerve stumps using the tubulization technique. Thus, polystyrene scaffolds, produced so as to replicate the basal lamina of peripheral nerves, lead to a neurite alignment parallel to the structure of the basal-lamina like tubes obtained in the preparation (Karlsson et al. 2011). Another interesting approach to obtain longitudinal organization of the artificial implant was proposed by Lu et al.

In addition to

dealing with the obstacles above, what is needed to decrease this are new approaches that deal with the brain changes produced by chronic dependence and could reverse the intracellular changes related to addiction and craving.
Innumerable reviews on addictive disorders have been written by many groups, including our own, over the past decade.1-17 We have contributed over 20 reviews, commentaries, perspectives, or viewpoints in the last 5 years. In 2004, my laboratory published a review article on ”Evolving AZD6244 supplier perspectives in neurobiological research in the addictions.“18 Therefore, for this state-of-the-art review with conceptual insights, focus will be placed Inhibitors,research,lifescience,medical on research conducted in our Laboratory and Center over the last 5 years. For further information and for some relevant citations of other research groups, one can consult some reviews which we have prepared Inhibitors,research,lifescience,medical on basic molecular neurobiology, with a focus on cocaine and other stimulant addictions, opiate addiction, and alcoholism.1-6 We have published other reviews and perspectives on research related to stress responsivity, Inhibitors,research,lifescience,medical and also genetics related to stress responsivity, and with emphasis on the role of stress responsivity.5,7,8,11 Further, and relatively exhaustive, reviews on human molecular genetics related to the addictions may be found in yet other recent publications from

our laboratory9,10 Finally, reviews of the history of treatment research Inhibitors,research,lifescience,medical in our own laboratory, as well as overviews of recent contributions of our group and others, have been published within the last 5 years.12-17

This review will be presented in three sections: (i) laboratory-based molecular neurobiological and neurochemical studies related to cocaine Inhibitors,research,lifescience,medical and opiate addiction and potential new approaches to treatment thereof; (ii) role of stress responsivity in the acquisition and persistence of specific addictive diseases, and the impact of chronic exposure to drugs of abuse and withdrawal there-from on components of the stress-responsive system, along with identification of potential new targets for therapeutic intervention; and (iii) basic clinical research related to specific addictive diseases, with emphasis on stress responsivity: all research focused on treatment improvement. Laboratory-based molecular neurobiological and neurochemical studies related to cocaine Bay 11-7085 and opiate addiction, and potential new approaches to treatment thereof Over the past several years, we have developed several animal models for acute, subacute, and chronic exposure to specific drugs of abuse, with emphasis on cocaine, morphlne and heroin, and alcohol. One of these models, which we have developed, validated, and used extensively in our studies, is “binge” -pattern cocaine administration mimicking the most common pattern of human abuse.

In the meantime, the most commonly used assessment tool in the ar

In the meantime, the most commonly used assessment tool in the area is the Inventory of Complicated Grief (ICG). It was developed by Prigerson and colleagues11 and focuses on symptoms that are distinguishable

from symptoms of depression and anxiety (eg, reactions such as preoccupation with thoughts of the deceased, disbelief about the death and nonacceptance of its reality). Moreover, the ICG was designed Inhibitors,research,lifescience,medical to distinguish between normal reactions and more pathological forms. The ICG consists of 19 Items (eg, “ever since she died it is hard for me to trust people”). Its convergent and discriminant validity yielded excellent results. High ICG values were associated with a lower quality of life. Moreover, scores at 6 months after loss predicted risk of cancer, high blood pressure, heart trouble, smoking, and eating problems 1 to 2 years later.23 In an attempt to compare the ICG with Horowitz’s concept of PGD, Forstmeier and Maercker24 Inhibitors,research,lifescience,medical conducted a comparative study using a 30-item questionnaire

according Inhibitors,research,lifescience,medical to the Horowitz model.9 They found only a small convergent validity between the two assessments. The authors concluded that the main reasons for this nonconvergence were the number of symptoms or criteria that had to be present In order to diagnose PGD. For the most recent consensus criteria on PGD (see above13), no validated clinical assessment has so far been published. However, a short screening scale, the PG-13, Inhibitors,research,lifescience,medical has been developed by Prigerson’s group14 and it has already been used in several studies (eg, ref 25). It is a promising tool to investigate PGD in various populations and has the advantage of being short and comprehensive. Epidemiology Inhibitors,research,lifescience,medical To date, there are no methodologically

sound studies that provide information about the prevalence of complicated grief in the JQ1 supplier general population. However, two issues are of particular interest. First, the general prevalence (eg, 1-year prevalence). The second is the conditional probability: the proportion of bereaved persons who develop PGD. Various authors have reported probabilities of around 10%, 13,26 implying that almost one third of all bereaved develop PGD. So far, Resveratrol the only representative epidemiological studies are on elderly samples, Including persons 60 to 94 years old.27,28 In the Swiss population within this age group, 4.2% of the 712 participants were diagnosed with PGD based on the previous Horowitz criteria.28 Women were diagnosed more often: 5.8% of all women, against 2.1% of men. The conditional probability was 16%, meaning that one out of six had the disorder. Patients with PGD had 1.9 (SD 1.0) comorbid psychiatric disorders with subthreshold depression as the most frequent comorbid condition. Further, 17% were receiving psychopharmacologlcal treatment, but not one PGD patient was in therapy.

The most important is the TH1 response by which proinflammatory mediators such as transforming growth factor beta (TGF-β) and tumor necrosis factors gamma (TNF-γ) are secreted. The latter activates matrix methyl proteinases, which degrade the matrix, eventually culminating in destruction of enterocyte villi, characteristic of CD. The TH2 pathway will stimulate the B cells to produce specific immunoglobulins including anti-gliadin and anti-tTG antibodies.1 We have demonstrated elevated prostaglandin

E2 and thromboxane B2 levels in the mucosa obtained from CD patients as compared with controls.10 Moreover, we have reported increased Inhibitors,research,lifescience,medical apoptosis in CD patients while on a gluten-containing diet, in PH-797804 solubility dmso comparison

Inhibitors,research,lifescience,medical to controls.11 CLINICAL PRESENTATION The clinical presentation of CD has shifted during the previous decades from the classical presentation in which the toddler suffers from diarrhea, constipation, vomiting, failure to thrive (FTT), abdominal distension, etc., to the child with a monosymptomatic presentation, such as anemia, bone disorders, and arthritis, as well as an Inhibitors,research,lifescience,medical enlarged list of extra-intestinal disorders (Table 1).12 Table 1 Whom to screen? DIAGNOSIS Who should be considered for screening for CD? Many diagnoses of CD are currently being performed following screening tests of first-degree relatives of CD patients; most of them are asymptomatic, others are diagnosed due to related disorders. The diagnosis of CD is being established by symptoms consistent with CD, positive serology, i.e. high anti-tTG, endomysial antibodies Inhibitors,research,lifescience,medical (EMA), and elevated deamidated gliadin peptide antibodies (DGP), encompassing IgG as well as IgA antibodies. As IgA deficiency is much more common in CD compared to the general population, the Inhibitors,research,lifescience,medical tTG and EMA, both belonging to the IgA immunoglobulin family, may be (false) negative in CD. Moreover, in young children, less than 2 years old, the incidence of false negative celiac serology is higher than later in life and should be taken into consideration while evaluating a

child with suspected CD. After demonstrating elevated celiac serology, the ultimate diagnosis should be made upon histological evaluation of the small bowel mucosa. The classical histopathologic findings are: villous atrophy, hyperplastic crypts, increased intraepithelial lymphocytes (IEL) infiltration (CD8), and increased Molecular Cell inflammatory cells infiltration in the lamina propria, as well as increased mitotic index. Many experts are using Marsh histological criteria, in which stage 1 is just IEL infiltration and stage 3c shows total villous atrophy. One should always anticipate the desired improvement of the patient while on a strict gluten-free diet (GFD). Recently, new modified guidelines for the diagnosis of CD have been published in the Journal of Pediatric Gastroenterology and Nutrition.

The security application could therefore be deduced according to

The security application could therefore be deduced according to the previously mentioned data and the optimal E.E. HepG2 and SP2/0 cells were transfected as described previously with either DNA/CTS-Fe3O4 or DNA/PEG-Fe3O4, with DNA/chitosan, DNA/lipofectamine, and naked plasmid as controls. Exposure to a permanent magnetic field (magnet) for 30min Inhibitors,research,lifescience,medical was followed

by 4h incubation. Concurrently, the control groups were routinely transfected using AP24534 purchase conventional methods. The highest transfection rates were achieved in HepG2 cells corresponding to 67.2% and 45.8% after transfected with CTS-Fe3O4 and PEG-Fe3O4 complexes. Significantly lower transfection rates of 14.3%, 8.7%, and 0.4% resulted from transfection with lipofectamine, chitosan, and naked plasmid, respectively. In addition, the transfection rates were significantly increased by 4.1-

and 3.2-fold in HepG2 and SP2/0 Inhibitors,research,lifescience,medical cells, when compared to cells not exposed to the magnetic field. Similar transfection results were also Inhibitors,research,lifescience,medical obtained with SP2/0 cells, and lower rates of 43.7% and 32.5% treated with CTS-Fe3O4 and PEG-Fe3O4 complexes were achieved. Compared with conventional transfected methods, the results were still statistically significant (Figure 4). Thus, the transfections rates enhanced by the assistance of magnetic field were verified again in HepG2 and SP2/0 cells. It seems that the use of a static magnetic field can improve the translocation

of the particles across the cell membrane. It has been reported that the higher transfection rates with magnetic nanoparticles were mainly attributed to their size surface charge, since the larger nanoparticles faster sedimentated on the surfaces of the cells, and this resulted Inhibitors,research,lifescience,medical in higher endocytic uptake, and positively charged nanoparticles were more easily taken up by cells [22]. The chosen cells used in our study were malignant cells from human and mice, Inhibitors,research,lifescience,medical and these cells differed in characteristics used as models for different human diseases. Thus, they were good representative samples for enhancement of delivery and effective targeting mafosfamide of gene expression. Furthermore, the EGFP expression was strong in transfected cells indicating that the function of DNA was kept and no fragmentation occurred. Figure 4 Magnet-assisted transfection of pEGFP plasmid. The SP2/0 cells were transfected with either polymer Fe3O4 or traditional transfection methods in the presence or absence of static magnetic field for 30min. A and B: magnet-assisted transfection; … Magnetic materials modified by biodegradable polymers as gene carriers possess many merits. For examples, simple manufacturing operation, arriving at the target point with the help of an outer magnetic field; a powerful surface energy effect and a small size effect are their outstanding characters.

Further studies will be necessary to examine a possible link between these behaviors. The observed changes in subunit expression in the pons are likely consequences of alterations in subunit synthesis, trafficking from intracellular compartments, or anchoring in the membrane. A number of scaffolding proteins that anchor GABAA receptor subunits have been identified. Gephyrin, a scaffolding protein that interacts primarily with subunits of synaptic receptors (Kneussel and Loebrich 2007; CT99021 ic50 Renner et al. 2008; Tretter and Moss 2008), is one participant in this process in some brain regions (Waldvogel et al. 2010). The fact that gephyrin mRNA levels are comparable in the pons of WT and Inhibitors,research,lifescience,medical α4 subunit-deficient mice

suggests that changes in receptor expression in this brain region occur independently of this protein. Additional studies are necessary to confirm that gephyrin protein levels are also unchanged and to determine whether Inhibitors,research,lifescience,medical the expression of other identified synaptic or extrasynaptic receptor interacting proteins is altered. In conclusion, our studies demonstrate that loss of the GABAA receptor α4 subunit modifies respiratory and anxiety-like behaviors. Accompanying these behavioral changes, the expression of GABAA receptor subunits is altered; these changes Inhibitors,research,lifescience,medical presumably

affect the balance between phasic and tonic GABAergic inhibition as well as that between inhibitory and excitatory signaling. Such adjustments in network activity may underlie the observed alterations in the respiratory pattern and the increased anxiety-like behavior in α4 subunit-deficient mice.

Major Digestive enzyme depression is a serious medical illness that affects more than 13% of adults in the U.S. during their lifetime (Hasin et al. 2005). The vast majority of depressed patients have normal peripheral thyroid indices (Joffe and Levitt 1993). However, the prevalence of subclinical hypothyroidism is significantly higher among depressed patients compared with the general population (Haggerty and Prange 1995) and over 63% of patients with subclinical hypothyroidism report depressive symptoms (Demartini et al. 2010). A rich body of literature has focused on thyroid hormone indices as predictors of antidepressant response outcome. In one study, relatively elevated free T4 index in depressed men was associated with a faster antidepressant response time as measured by length of hospital stay (Abulseoud et al. 2007).

Nevertheless, the European Commission has developed a number of initiatives with emphasis on safety and ethical considerations but also to evaluate the appropriateness

of existing methodologies to assess the potential risks associated with nanotechnology. In this context, it is mentioned that there is still insufficient knowledge and data concerning nanoparticles characterization, their detection and measurement, the persistence of nanoparticles in humans and the environment, and all aspects of toxicology related to these particles to allow satisfactory risk assessments. In order to deal with this issue, the EMEA has created the Innovative Task Force for the coordination of scientific and regulatory Inhibitors,research,lifescience,medical ARRY-162 nmr competence. Because novel applications of nanotechnology will span the regulatory boundaries between medicinal products and medical Inhibitors,research,lifescience,medical devices, the mechanism of action will be the key to decide whether a product should be regulated as a medical product or a medical device. Furthermore, evaluation of the quality, safety,

efficacy, and risk management must be discussed in more detail. In conclusion, it is likely that the evaluation of such new products will require special considerations. Therefore, EMA will promote this process either to develop specific Inhibitors,research,lifescience,medical guidelines or for the update of existing once. 2. Preparation Techniques 2.1. General Introduction into Techniques Lipid molecules have to be introduced into an aqueous environment for the preparation of

liposomes independent of liposome size and structure. A general overview representing Inhibitors,research,lifescience,medical the correlation of the way of lipid hydration, respectively, the way of primary liposome formation with the resulting liposome structure, was originally developed by Lasic [38]. Several ways of treating the lipids are known to support the hydration of these molecules, as lipid molecules themselves are poorly soluble in aqueous compartments. These procedures can be categorized as shown in Table 2. Table 2 Methods of liposome preparation and the resulting product. Partly from Lasic and Barenholz [39]. Additional methods have Inhibitors,research,lifescience,medical been developed such as freeze thawing, freeze drying, and extrusion. Neuron – Cell However, they are all based on preformed vesicles. In the following sections, liposome preparation techniques are described with respect to the principle of lipid hydration/liposome formation as well as process design and description. In addition, the advantages and disadvantages of each technique are pointed out. Furthermore, focus is given on discussing the techniques with respect to their applicability regarding large-scale production for clinical purposes and good manufacturing practice (GMP) relevant issues. 3. Mechanical Methods 3.1. Preparation by Film Methods Properties of lipid formulations can vary depending on the composition (cationic, anionic, and neutral lipid species).
