NSAIDs, both indomethacin and celecoxib, are effective in treating BS. The latter has demonstrated benefits on severity of GI tract involvement and decreasing in hyperfiltration. However, the safety profile of celecoxib may, in the future, allow for its use as first drug for the treatment of BS. In patients who develop proteinuria, enalapril was effective in reducing it. Thus, it is suggested to start the treatment with celecoxib and if necessary replacing it by ACEi. This study PLX3397 manufacturer has some limitations, such as the small number of patients and lack of a genetic assessment. Randomized, larger and controlled studies are needed to

confirm the present data. However, it is a rare disease, and the present study had one of the largest series in the literature. The authors declare no conflicts of interest. “
“The superiority of human milk (HM) feeding in preterm newborns (PNs) is well documented. HM has an important impact on brain growth and development, even when it buy ZD6474 does not promote great weight gain, supporting the concept that the optimal postnatal growth of PNs is not yet known.1, 2, 3, 4 and 5 Regarding the supply of proteins, not only

the quantity but also the quality is important for proper growth. The amino acid composition of formulas and additives to human milk using bovine protein has reduced quality in relation to HM,6, 7, 8 and 9 which is considered the gold standard. The protein fraction of cow’s milk has a predominance of casein, which has high content of the amino acid phenylalanine.10 Although it is an essential amino acid in children receiving cow’s milk protein, plasma levels of this amino acid are high (close to those associated with metabolism defects).11, 12 and 13 The increased intake and plasma levels of phenylalanine results in the inhibition of the enzyme tyrosinase, and subsequent conversion, through hydroxylation, of phenylalanine into tyrosine, increasing tyrosine availability. This increase

can cause a deleterious effect on brain development, leading to consequences such as sleep disturbance, GNAT2 memory deficits, and attention and concentration deficits.14, 15, 16 and 17 While the optimal nutrition for PNs is unknown, neonatologists should be committed to what appears to be ideal, which does not result in changes in the short-term, and provides better long-term development. In this context, supplementing HM with an additive containing a protein homologous to that of HM appears to be a suitable alternative for protein supply, while maintaining safe plasma levels of phenylalanine.18, 19 and 20 Considering this hypothesis, this study aimed to comparatively analyze plasma levels of phenylalanine in PNs fed banked human milk (BHM) plus the commercial additive FM85 (Fortified Milk 85, Nestlé, São Paulo, Brazil) and PNs fed with BHM plus an additive derived from the HM itself, after removal of fat and lactose in evaporated or lyophilized forms.

30 The zinc dose used in this study is another important variable

30 The zinc dose used in this study is another important variable to consider, as it may have been insufficient to achieve the expected effect, as the recommended dose for treatment and prevention of DD and ARI is 10 to 20 mg/day.12 Larger amounts of zinc were not offered as the objective was to evaluate the supplementation

through the use of sprinkles with 5 mg/zinc, whose recommended use is of one sachet/day.15 Therefore, in a healthy population, zinc supplementation with 5 mg/day may not be as effective in the prevention of infectious diseases. Regarding acceptance, sprinkles appear to be an efficient way of supplementing zinc intake, as well as other TSA HDAC mw micronutrients. The data analyzed in this study reflect an acceptance > 90%. It is noteworthy the fact that the sprinkles were added to the food that was best accepted by the participants and, as they provide almost no change in

flavor or color of preparations, their consumption may be associated with the acceptance of the food offered to the children. Other studies that assessed the acceptance of sprinkles16 and 17 also showed similar results, suggesting they are a good option to fight micronutrient deficiencies, especially because they do not alter the organoleptic characteristics of food. Based on the present study, it can be concluded that zinc supplementation through the use of sprinkles had no impact in reducing the incidence of DD and ARI, nor influence on the nutritional status of the study population. However, the good acceptance Akt inhibitor of sprinkles offers a new form to administer supplemental micronutrients, representing an innovation in the management of children’s nutritional deficiencies. The sprinkles were donated by Emory University, Atlanta, GA, USA. The authors declare no conflicts of interest. “
“Environmental Glutamate dehydrogenase tobacco smoke (ETS) is associated with a higher prevalence of asthma in adolescents, and with more severe

forms in children. Passive exposure to tobacco smoke is common, and its damaging effects on health have been well-known for decades.1 However, the magnitude of the problem worldwide is poorly described2. Childhood asthma is one of the diseases that most contributes to the health costs arising from passive smoking.2 It was estimated that 603,000 deaths were attributable to second-hand smoke in the year 2004, representing 1% of world mortality, of which 28% occurred in children.2Although the higher prevalence and severity of childhood asthma due to ETS appears to be well-established,3, 4, 5 and 6 other studies report that ETS is not associated with a higher prevalence of asthma in children.7, 8 and 9 The aim of the present study was to analyze the prevalence of asthma symptoms in children and adolescents in this community, according to the passive exposure to smoking by the parents.

However, there was no significant difference between the Dox–PEG

However, there was no significant difference between the Dox–PEG group and the free Dox group, whereas the tumor growth inhibition efficacy of the AG73–Dox group was better than that of the free Dox group (P<0.05). When the see more antitumor effect of Dox–PEG was compared with that of AG73–Dox, there was no significant difference in antitumor effect. We also monitored the body weights of the tumor-bearing mice to assess any side effects of AG73–Dox. The body weight change during the tumor treatment was not observed in the AG73–Dox group. To evaluate the targeting effect of AG73 peptide-modified liposomes in vivo, we examined the intratumoral

localization of AG73 peptide-modified liposomes. As shown in Fig. 8, DiI-labeled PEG liposomes (PEG-L), which did not

contain Dox, were leaked from intratumoral vessels and diffused in the tumor tissue, whereas DiI-labeled AG73 peptide-modified liposomes (AG73-L) were mainly bound to intratumoral vessels and were partially extravasated in the tumor. The AG73 peptide is a ligand for syndecan-2. Syndecan-2 is also highly expressed in human vascular endothelial cells [17]. Moreover, the cellular uptake of AG73–Dox in human umbilical vein endothelial cells was higher than that of Dox–PEG or AG73T–Dox, which was observed using flow cytometry (data not shown). In this study, there is little difference between antitumor effect of Dox–PEG and that of AG73–Dox. However, it seems that AG73–Dox PLX3397 purchase tend to target not only tumor tissue but also intratumoral

vessels ( Fig. 7 and Fig. 8). To assess whether AG73-L is tumor selectivity, we injected DiI-labeled PEG-L or AG73-L and observed various other organs (heart, liver, spleen, and kidney) using fluorescence microscopy. As shown in Fig. 9, although the fluorescence intensity of AG73-L was slightly high in the heart compared to that of PEG-L, there was little difference between PEG-L and AG73-L in the other organs. Recently, to enhance the therapeutic effect of Dox, the drug delivery field has focused its attention on designing nanoparticles that are capable of releasing a drug efficiently when exposed to a specific triggering mechanism [1] and [2]. Such triggers include pH, light, ultrasound, enzymatic action, and heat [13]. Among the trigger-sensitive nanoparticle Sitaxentan formulations that have been developed, ultrasound-sensitive liposomes (bubble liposomes) could function as a novel gene delivery tool by exposure to ultrasound [25] and [18]. Therefore, it is necessary to optimize the AG73–Dox for in vivo application by changing the peptide modification ratio or PEG ratio. Furthermore, the combination of AG73–Dox with bubble liposomes and ultrasound may enable enhancement of the therapeutic effect. In this study, doxorubicin-encapsulating AG73 peptide-modified liposomes (AG73–Dox) were developed to increase the intracellular uptake of anticancer drugs and to achieve an improved therapeutic effect specifically against tumors.

However, 2-D proteomic analyses indicated three groups of crystal

However, 2-D proteomic analyses indicated three groups of crystallin. The most likely explanation is PD0325901 order that crystallin undergoes post-translational modification, dimerization, and oligomerization. It is not known whether nodavirus infection in groupers affects these processes, thereby interfering with the biological functions of crystallins. Crystallin is regulated by temperature [34] and undergoes folding

under normal physiological conditions, which support a chaperone-like activity. Therefore, an experiment was done where grouper cells were infected with the nodavirus at 28 °C and 32 °C. No temperature-related differences in expression mRNA and protein were evident. However, after viral infection, immunohistochemical staining showed that crystallin proteins clustered within cells forming puncture spots ( Fig. 5). With increased temperature and Crenolanib ic50 viral infection, the probability of intracellular puncture formation also increased. The results are consistent with the view that crystallin is a stress-induced protein. Using human crystallins as an example, under normal conditions, crystallin assembles into high order forms [34]. However, under stress situations, grouper crystallin assembles into puncture forms, which helps to unfold abnormal proteins back into normal proteins, performing chaperone-like functions. PolyQ proteins fused with

green fluorescent protein (GFP) were used to monitor the aggregation of misfolded proteins [35], therefore, we evaluated firstly whether recombinant polyQ-GFP CHIR-99021 solubility dmso reproduces key features, accumulated in inclusion body-like aggregation in vitro. GFP fluorescence was observed under the control of E. coli expression system. In marked contrast, when different length polyglutamine fused to GFP were expressed, distinct fluorescent images were observed in expressing proteins. Recombinant GFP (r-GFP) and recombinant Q5GFP (r-Q5GFP) were diffusely distributed, whereas the recombinant Q9GFP (r-Q9GFP) accumulated partially in inclusion body-like aggregation ( Fig. 6A). Analysis of total extracts proteins were

subjected to high speed centrifugation, r-GFP remained exclusively in the soluble supernatant fraction, whereas a significant portion of both r-Q15GFP and r-Q21GFP were found in the insoluble pellet fraction ( Fig. 6B). Next, we evaluated whether grouper crystallin reduced the amount of aggregates of r-Q9GFP. As shown in Fig. 6C, fluorescence microscopy revealed that both recombinant crystallin (r-crystallin) and heat shock protein 90 (r-HSP90) reduced r-Q9GFP aggregation in vitro. In contrast, both r-crystallin and r-HSP90 did not alter aggregated r-Q9GFP to form soluble r-Q9GFP ( Fig. 6D). In this study, grouper crystallin processes chaperone-like properties, including the ability to prevent the aggregation of misfolded proteins.

0 pg/mL, and his Aspergillus galactomannan antigen index was 0 4

0 pg/mL, and his Aspergillus galactomannan antigen index was 0.4 at three months after the start of treatment. During the study period, the fibrotic pulmonary cavity enlarged (Figs. 1 and 3), and the patient’s pulmonary function deteriorated in accordance with the progression of his IPF. Chemically-induced bronchitis and drug-induced interstitial lung disease were considered

to be potential side effects of the abovementioned treatment regimen, but neither of these conditions developed. In addition, no L-AMB-related renal dysfunction or hypokalemia were observed. The abovementioned treatment was so effective that the patient’s Y-27632 hemoptysis disappeared within two weeks and his aspergilloma shrank within three months and had completely disappeared within seven months. Aspergillus is a ubiquitous fungus, and all human

beings breath in its conidia during everyday life. However, any conidia that attach to the lower respiratory tract are removed by mucociliary clearance, and those that reach the alveoli are phagocytosed by alveolar macrophages [5]. Furthermore, even when the conidia sprout hyphae they are sterilized by neutrophils [6], resulting in healthy hosts escaping from fungal infection. Aspergillus can cause a variety of diseases depending on both the immunological status of the host and the local condition of the lung http://www.selleckchem.com/products/PLX-4032.html [1] and [2]. Pulmonary aspergillomas usually occur in pre-existing lung cavities exhibiting local immunodeficiency, such as those caused by tuberculosis, bronchiectasis, emphysema, pneumoconiosis, sarcoidosis, and interstitial pneumonia [3]. Pulmonary aspergillomas are classified into simple and complex aspergillomas [7], and the latter type is more prevalent because it is associated

with underlying diseases. Surgery such as cavernostomy with muscle transposition, partial resection, segmentectomy, or lobectomy [9], [10] and [11] Verteporfin cost is recommended as a curative treatment [8]. Although less invasive surgical strategies such as cavernostomy have been developed, underlying diseases can make the optimal surgical procedure very difficult. For those patients who are unsuitable for surgery, amphotericin B (AMPH-B), L-AMB, VRCZ, ITCZ, and micafungin sodium are utilized as systemic antifungal agents because they are effective against invasive aspergillosis and chronic necrotizing pulmonary aspergillosis [12], [13] and [14]; however, there is no evidence from randomized controlled studies to support the use of these drugs against aspergillomas, with some reports suggesting that systemic AMPH-B administration is ineffective [15] and oral ITCZ only achieves limited outcomes [16]. The optimal treatment duration has not been established and varies from several months to years, even in cases in which treatment is effective. The limited response rates of systemic antifungals are due to poor drug delivery to saprophytic fungus balls [4], and severe side effects can sometimes lead to treatment cessation.

[36] and [37] used finite-element stress analyses to demonstrate

[36] and [37] used finite-element stress analyses to demonstrate that tensile and shear bond-strength

measurements were highly dependent on the geometry of the test apparatus, the nature of the load application, the presence or absence of adhesive flash and the materials involved. The authors reported that non-uniform stresses acted upon the bonded interface; they therefore questioned the concept of ‘average stress’ for measurements of bond strength. The greatest emphasis has been placed on measuring tensile bond strengths (at right angles to the tooth/adhesive interface). All of the forces acting on an adhesive bond in vivo can be resolved as components acting at right angles and parallel to the interface www.selleckchem.com/products/PD-0325901.html (shear). It is therefore important to measure the shear strength in order to evaluate a bond adequately. Bond strength-testing jigs have been designed such that the maximum stress in the shear apparatus is transmitted along the interface, whereas the stresses for the tensile bond strength

are transmitted through the adhesive to the interface. The path of a fracture placed under tension will therefore pass through the weakest areas in the bulk of the adhesive or the interface. One problem with tensile tests is that the force is transmitted Crenolanib through the body of the adhesive, and partial cohesive failure, rather than interfacial failure, often occurs [38]. The consequent variation among specimens might obscure the interfacial bond strength. When a resin composite bonded to a flat dentin surface

is loaded in tension or shear, the distribution of stresses along the interface is extremely irregular. For shear strengths, Fludarabine the stress is concentrated at the interface, and the fracture path will not readily deviate unless there is a major flaw either in the adhesive or at the dentin surface [36], [37] and [38]. The shear bond strength might be related to the elastic modulus of the adhesive. Increasing the modulus of elasticity will result in a more uniform distribution of stress over the bonded area, and avoid a concentration of stress at the point of load application. An extremely low elastic modulus will cause the fracture to have a peeling character rather than a shear character. The elastic modulus of restoratives has been reported to increase roughly in line with increasing shear bond strength [39]. When determining the shear bond strength, the maximum force is exerted along the interface and, in practice, a more reproducible interfacial fracture is observed, with much less cohesive failure [40]. The shear bond strength of a dentin-bonding system is dependent on the adhesive mechanism; similar results are not expected to be obtained with different adhesive systems. A lapping shear test or a knife-edge test is most commonly used, and a notch effect at the knife-edge tip should be taken into consideration.

Characteristic X-ray generated with high energy X-ray irradiation

Characteristic X-ray generated with high energy X-ray irradiation is called as “fluorescent X-ray”. Each element has unique energy level sets of electrons; therefore, emitted X-ray energies are characteristic of each element. Table 2 shows examples of characteristic X-rays energies emitted from various elements [1]. Characteristic X-rays can be used to perform an elemental analysis by electron or X-ray irradiation. EPMA and SEM/EDS are popularly used for micro-elemental analysis because they simultaneously provide electron microscopic images and elemental distribution images. However, there are some requirements for specimens in

electron microscopy observation. The specimen should have electroconductivity RO4929097 cell line (or an electroconductive coating) and kept under a high vacuum during observation. Therefore, wet specimens (e.g., cells or wet tissue) Baf-A1 in vitro and specimens with a low heat resistance (e.g., paraffin-embedded tissue) are hard to analyze using EPMA or SEM/EDS methods. In addition, there is some possibility that electron irradiation can damage the specimens. Thus, high skills are required for the specimen preparation and observation for the EPMA or SEM/EDS analyses of scarce specimens [2]. X-ray fluorescence analysis (XRF) uses characteristic X-rays (called “fluorescence X-rays”) emitted under high-energy X-ray irradiation. XRF has some advantages over EPMA and EDS as follows. (1) X-ray irradiation

and fluorescence X-ray detection can be carried out in air, because X-rays are easily transmitted in an air layer. Therefore, XRF analysis can be performed in air and evacuation of the specimen chamber is not Exoribonuclease necessary, as it is in electron microscopy methods. In dental and medical analyses, specimens that are wet and/or have low heat resistance are often requested for elemental analysis. Additionally, scarce

pathological specimens should be analyzed non-destructively. The features of XRF are quite appropriate for such specimens. Conventional XRF irradiates an unfocused, wide beam onto the specimen. Therefore, a large specimen surface was required for analysis. Recently, a micro-focused X-ray source has been developed; thus, micro-sample analysis and elemental distribution analysis have become available. The optics for visible light are created by transparent materials with refractive indices greater than 1. However, for X-rays, materials have a refractive index almost equal to 1; therefore, different optics are required for X-ray focusing. Capillary focusing is widely used for XRF focusing optics. The inner surface of the capillary is designed to be the paraboloid of revolution, and the total reflection from the inner surface guides the X-ray to the focus. XRF analysis while scanning the specimen additionally provides elemental distribution images. A schematic diagram of micro-focused XRF equipment is shown in Fig. 2. Spatial resolution, which depends on the focus size, is 10–100 μm.

Accordingly, the present study evaluates the effects of vitamin E

Accordingly, the present study evaluates the effects of vitamin E supplementation on the fatty acid profile of Nile tilapia carcasses. The experiments were carried out in an experimental laboratory

at the Department of Animal Biology – UFV over 106 d (9 Jan to 25 Apr, 2005). The 400 sex-reversed, early juvenile tilapias (Oreochromis niloticus), weighing 1.40 ± 0.88 g and measuring 4.77 ± 0.37 cm, were obtained from a reputable producer. They were distributed among twenty 1000-l tanks ( Souza, Castagnolli, & Kronka, 1998), renewal with water at a constant rate of 7.5 mL/min and 12 light/12 dark photoperiod. To assess fish performance, a completely randomized design was established, with RG7420 ic50 five treatments (4 repetitions each) consisting of the addition of vitamin E monophosphate at 0, 50, 100, 150 and 200 mg/kg of a base

diet composed of 36% crude protein and 3600 kcal of digestible energy/kg. Treatments were initiated after a 5-day adaptation period to the base diet. The diets were composed of 21.5% soybean meal, 30% corn gluten, 28.50% corn, 9% of fish meal, 7.60% soybean oil, 1.37% phosphate dicalcium, 0.51% l-methionine, 0.60% NaCl, 0.60% vitamin premix and mineral-free vitamin E, 0.15% lysine and 0.02% BHT. The percentage of Docetaxel vitamin E was added to the experimental diet at levels of 0 mg/kg, 50 mg/kg, 100 mg/kg, 150 mg/kg and 200 mg/kg. Diets were pelleted and portions corresponding to 5 percent of body weight were offered three times a day (8:00, 13:00 and 18:00 h). Portion size was adjusted every 15 d to accompany fish growth. Fifteen percent of the fish were collected in 3 cm-mesh nets and measured with a caliper and precision scale. A 12:12 h light/dark cycle was adopted. Temperature was measured twice a day (7:00 and 17:00 h)

and pH, dissolved oxygen and ammonia every 7 d. After the 106-day experiment and a 24-h fast, the fish were anesthetized with benzocaine and sacrificed. Carcasses were weighed on a precision scale (0.001 g) to determine initial carcass Meloxicam composition. For chemical analyses, carcasses were dried in a forced ventilation oven at 55 °C for 48 h. The dried carcasses were then ground in a ball mill until the particle sizes were homogenous. Analyses of crude protein was determined by the micro Kjeldahl method (titration with 0.05 N sulphuric acid), the ether extract was determined by extraction with ethyl ether for 30 h, the mineral content was determined after incineration in muffle at 550 °C for 4 h, and crude fibre was determined by digestion with sulphuric acid 1.25 N and sodium hydroxide 1.25 N. The analysis of the ingredients used in the diets and fish samples, were performed at the Laboratory of Animal Nutrition Department of Animal Science (LNA / DZO), University Federal of Minas Gerais – UFMG. The procedures are in accordance with AOAC (1995).

22 μm PTFE syringe filter For the stationary phase, a monomeric

22 μm PTFE syringe filter. For the stationary phase, a monomeric C18 ODS2, 5 μm, 4.6 × 150 mm (Waters Spherisorb®, Wilmington, USA) was used. The mobile phase consisted of acetonitrile (containing 0.05% of triethylamine), methanol and ethyl acetate. A concave see more gradient was used for C. moschata ‘Menina Brasileira’ from 95:5:0 to 60:20:20 for 20 min, maintaining this proportion until the end of the run. For the C. maxima ‘Exposição’, a gradient from 98:2:0 to 60:20:20 for 20 min was used. Reequilibration took 15 min in both cases. The flow rate was 0.5 ml/min and column temperature was kept at 35 °C. The identification of the carotenoids was performed

considering (a) the combined information from chromatographic parameters (retention time and elution order), (b) UV–visible spectrum parameters (λmax and spectral fine structure % III/II) compared to standards and to data available in literature, (c) co-chromatography with standards and (d) chemical reactions to verify the type Selleck ZD1839 and position of the

substituents in the xanthophylls ( Pfander et al., 1994 and Schiedt and Liaaen-Jense, 1995). The chemical reactions were acetylation of secondary hydroxyl groups with acetic anhydride, methylation of hydroxyl groups in allylic position with acidified methanol, iodine catalysed isomerisation and epoxide-furanoxide rearrangement (5,6-epoxide–5,8-epoxide) with dilute HCl ( Rodriguez-Amaya, 1999). The major carotenoids in each sample were quantified by using calibration curves prepared from standards,

and the results were expressed as μg/g of sample. Standard curves were constructed with five different concentrations for each carotenoid, each point in duplicate, with lines passing by origin and coefficients of co-relation greater than or similar to 0.95. Violaxanthin was quantified with the standard curve of lutein, and the cis-isomers of β-carotene with the standard curve of all-trans isomer ( Assunção & Mercadante, 2003). Due to the difficulty of isolating the ζ-carotene standard, its quantification was performed Benzatropine through the standard curve of the all-trans-β-carotene. The standards used in this work were isolated from other plant species, such as carrots and green vegetables, by using open column chromatography (OCC), according to Kimura and Rodriguez-Amaya (2002), with a glass column of 2.5 × 25 cm packed with MgO:Hyflosupercel (1:1), activated for 2 h at 110 °C and developed with petroleum ether containing varying quantities of acetone and ethyl ether. Concentrations of the standard solutions were determined through a spectrophotometer (Hitachi, U-1800, Tokyo, Japan) and corrected according to their purity through HPLC, considering 90% as minimum purity to be used as standard. Many studies that propose to investigate retention of carotenoids in processed foods do not take into account the gain or loss of weight during processing through incorporation or through loss of water or water soluble solids.

The OECD 408 guidelines are designed to test for carcinogenicity

The OECD 408 guidelines are designed to test for carcinogenicity of compounds. The guidelines provide details on how such a feeding study should be

conducted, including information on sample size, duration etc. However, the guidelines do not specify the histopathological analysis that should be performed. For example, what histopathological parameters should be used to detect or measure the carcinogenicity of a compound. Whilst it’s our view that histopathological methods to determine carcinogenicity are well Ceritinib mw established in the scientific community, the effect of GM feed on animal health is not. In addition, the carcinogenic potential of a GM crop is not, and should not http://www.selleckchem.com/products/Gemcitabine-Hydrochloride(Gemzar).html be, the only pathology investigated. Therefore, there is a question as to whether these OECD guidelines are relevant to investigation of the safety of consuming GM crops. Whilst they may be used as a starting point, it is our view that guidelines should be established specifically for GM crops. Since GM food is considered to be a novel food, the guidelines should list details for a thorough investigation that includes a histopathological analysis of the gut and other organs. In other models of GI tract damage, such as mucositis (Howarth et al., 1996, Logan et al., 2009 and Sukhotnik et al., 2008), neonatal adjustment of piglets to normal diet (Godlewski et al., 2009 and Strzalkowski et

al., 2007), or in gastric biopsies (Fenoglio-Preiser, 1998 and Staibano et al., 2002), the analytical method is detailed

and specific, listing the changes that need to be investigated and the microscopic techniques C1GALT1 and morphometric analyses that need to be used. For example, mitosis, apoptosis and autophagy are known to be good indicators of mucosal regeneration in the small intestine following injury. Therefore, immunohistochemistry with in-tissue cytometry looking at the expression of markers for mitosis (Ki67), apoptosis (caspase 3) and autophagy (MAP I LC3) can be used to assess mucosal regeneration (Godlewski et al., 2009). In mucositis-induced models, the investigation of the degree of damage regularly requires not only detailed quantitative histological analyses to be conducted (Howarth et al., 1996, Logan et al., 2009 and Sukhotnik et al., 2008), but also immunohistochemistry for markers of apoptosis (caspase 3), cell proliferation (BrdU) (Sukhotnik et al., 2008), and pro-inflammatory cytokines (such as TNF, IL-1β and IL-6) (Logan et al., 2009). Such vigorous analyses allow for a more precise assessment of possible pathological changes, whilst at the same time decreasing the chance of subtle changes being overlooked. Therefore, it is our view that in the investigation of the safety of GM crops on animal and human health, such a vigorous and in-depth approach should also be implemented.
