Abstract
This study retrospectively analyzed the clinical outcomes of endoscopic resection of 26 sporadic (i. e., not associated with polyposis syndrome) nonampullary duodenal lesions representing high-grade dysplasia or intramucosal carcinoma (duodenal HGD/IMC) in 23 patients. No severe complications such as perforation were observed, but three cases of delayed bleeding were seen. The use of endoscopic clips significantly decreased the delayed bleeding rate (0/19, 0%) compared with cases in which clips were not used (3/7, 42.9%; P = 0.013, χ2 test). Eighteen lesions (69.2%) were removed by en bloc resection. The follow-up period after resection was 25.5 ± 23.3 months. Two lesions (7.7%) that recurred locally were detected at the first surveillance endoscopy 3 months after resection. These lesions were 22 and 15 mm in size respectively and were resected piecemeal. Endoscopic resection is an effective and safe procedure for treating duodenal HGD/IMC. En bloc resection and prophylactic clip usage are encouraged.

Differential cellular localization of antioxidant enzymes in the trigeminal ganglion. Neuroscience 2013; 248:345-58.

Abstract
Because of its high oxygen demands, neural tissue is predisposed to oxidative stress. Here, our aim was to clarify the cellular localization of antioxidant enzymes in the trigeminal ganglion. We found that the transcriptional factor Sox10 is localized exclusively in satellite glial cells (SGCs) in the adult trigeminal ganglion. The use of transgenic mice that express the fluorescent protein Venus under the Sox10 promoter enabled us to distinguish between neurons and SGCs. Although both superoxide dismutases 1 and 2 were present in the neurons, only superoxide dismutase 1 was identified in SGCs. The enzymes relevant to hydrogen peroxide degradation displayed differential cellular localization, such that neurons were endowed with glutathione peroxidase 1 and thioredoxin 2, and catalase and thioredoxin 2 were present in SGCs. Our immunohistochemical finding showed that only SGCs were labeled by the oxidative damage marker 8-hydroxy-2'-deoxyguanosine, which indicates that the antioxidant systems of SGCs were less potent. The transient receptor potential vanilloid subfamily member 1 (TRPV1), the capsaicin receptor, is implicated in inflammatory hyperalgesia, and we demonstrated that topical capsaicin application causes short-lasting mechanical hyperalgesia in the face. Our cell-based assay revealed that TRPV1 agonist stimulation in the presence of TRPV1 overexpression caused reactive oxygen species-mediated caspase-3 activation. Moreover, capsaicin induced the cellular demise of primary TRPV1-positive trigeminal ganglion neurons in a dose-dependent manner, and this effect was inhibited by a free radical scavenger and a pancaspase inhibitor. This study delineates the localization of antioxidative stress-related enzymes in the trigeminal ganglion and reveals the importance of the pivotal role of reactive oxygen species in the TRPV1-mediated caspase-dependent cell death of trigeminal ganglion neurons. Therapeutic measures for antioxidative stress should be taken to prevent damage to trigeminal primary sensory neurons in inflammatory pain disorders.

Abstract
BACKGROUND The obturator hernia sac may follow the anterior or posterior branch of the obturator nerve, and thus, it can be classified anatomically. The relationship between the symptoms and the anatomical classification of obturator hernia has not yet been clearly described in the literature. METHODS Multidetector-row computed tomography (MDCT) examinations of 35 consecutive cases of new-onset obturator hernia admitted from March 2005 to April 2012 were reviewed retrospectively. Obturator hernia was classified anatomically using MDCT. Patient characteristics and clinical presentations were compared among the anatomical classifications. RESULTS Fifteen cases were classified as type I (anterior branch type) and 20 cases as type II (posterior branch type). There were no significant differences regarding time from onset of symptoms to diagnosis, presence of small bowel obstruction, and need for bowel resection. The Howship-Romberg sign was seen in 6 cases (30 %) of type II and 10 cases (67 %) of type I (p = 0.044). CONCLUSIONS The Howship-Romberg sign was present significantly more often with the anterior than the posterior branch type of obturator hernia.

Abstract
The absorption, distribution and excretion of radioactivity were investigated in male Sprague-Dawley rats after a single intravenous or subcutaneous dose of 14C-azacitidine. After subcutaneous administration, 14C-azacitidine was rapidly absorbed and the radioactivity was distributed to the tissues. The absorption of radioactivity after subcutaneous administration was 76.6% of that observed after intravenous administration. There were no marked differences in the tissue distribution of the radioactivity between administration routes. The concentrations of radioactivity in most tissues, including the spleen and bone marrow, which are sites of action of azacitidine, were higher than those in the plasma. Particularly high concentrations of radioactivity were detected in the spleen, kidney and liver. The accumulation of radioactivity in blood cells increased from 0.5 to 48 h. The binding of azacitidine to serum protein was low at <9%, and the cumulative urinary and fecal excretion of radioactivity for 168 h after intravenous or subcutaneous administration was >95% of the administered dose, indicating that radioactivity did not accumulate in the tissues. The radioactivity was mainly excreted in the urine.

Abstract
The epithelial-mesenchymal transition (EMT) is a crucial event that occurs during cancer metastasis and can be induced by transforming growth factor-β (TGF-β) in various tumor cells in vitro. However, little is known about the effects of TGF-β in canine mammary gland tumors (CMGTs). Here, we investigated the role of TGF-β in CMGT. We observed that treatment of the CMGT cell line CHMp13a with TGF-β1 leads to transient induction of the mesenchymal marker vimentin. Real-time measurements of cellular electrical impedance also showed that CMGT invasiveness is transiently increased by TGF-β1 treatment, but is reversed after prolonged stimulation. This phenomenon is similar to the mesenchymal-epithelial transition (MET, the reverse phenomenon of EMT), and a process that is implicated in the establishment of secondary metastatic lesions.

Abstract
Yokukansan (YKS) is a traditional Japanese medicine consisting of seven medicinal herbs that is used for the treatment of neurosis, insomnia, and the behavioral/psychological symptoms of dementia. This study examined the effects of YKS on morphine tolerance and physical dependence in mice. Daily oral administration of YKS (0.5 or 1.0 g/kg) for 3 weeks significantly attenuated morphine tolerance and naloxone-precipitated morphine withdrawal signs (jumps and body weight loss) without affecting the analgesic effect of morphine. The inhibitory effect of YKS on withdrawal jumps in morphine-dependent mice was blocked by a single pretreatment with an α(2)-adrenoceptor antagonist, yohimbine, but not by an α(1)-adrenoceptor antagonist, prazosin. A similar inhibitory effect on withdrawal jumps was observed by repeated administration of yohimbine. The membrane expression of α(2A)-adrenoceptors in the pons/medulla was decreased in morphine withdrawn animals; this reduction was prevented by repeated administration of YKS or yohimbine. Competitive radioligand and [(35)S]guanosine-5'-O-(3-thiotriphosphate) binding assays revealed that YKS and its constituent herbs, Glycyrrhiza (GR) and Uncaria hook (UH), had specific binding affinity for and antagonist activity against the α(2A)-adrenoceptor. Certain chemical constituents, including GR -derived glycyrrhizin and its metabolite, 18β-glycyrrhetinic acid, and UH-derived geissoschizine methyl ether (GME), shared such activities. Repeated administration of GR, UH, glycyrrhizin or GME significantly inhibited morphine withdrawal signs. These results suggest that YKS and its active constituents inhibit morphine tolerance and physical dependence, and that the latter is due at least in part to the prevention of the decreased membrane expression of the α(2A)-adrenoceptor in the brainstem by its prolonged blockade.

Abstract
BACKGROUND When treating patients with severe ulcerative colitis (UC), accurate prediction of drug efficacy contributes to early clinical decision-making. AIM To identify predictive factors and to develop a reliable prediction formula and a decision tree of response to intravenous ciclosporin treatment for severe UC. METHODS Patients included in this study were those diagnosed with refractory severe UC who had undergone ciclosporin treatment between December 2004 and March 2011 at a tertiary referral centre in Japan. Demographic and clinical parameters from all patients were analysed by multivariate statistics. RESULTS Fifty-two patients were included in this study (36.5% men with an average age of ciclosporin initiation of 40.2 ± 15.6 years). Thirty-four patients (65.4%) were responders to the treatment with ciclosporin and avoided colectomy, 18 patients (34.6%) were nonresponders and underwent colectomy. Stepwise multiple logistic regression analysis identified four independent predictive factors of response to intravenous ciclosporin: age at hospitalisation (AGE), platelet count (×10(4) /μL) on the first day (PLA), Lichtiger score on the third day (LIC) and total protein (g/dL) on the third day minus total protein on the first day (ΔTP). The calculation formula (8.5 - 0.16 × AGE + 0.21 × PLA - 0.61 × LIC + 2.3 × ΔTP < 0) predicted colectomy with an accuracy of 88.5% and the decision tree predicted colectomy with an accuracy of 90.4%. CONCLUSION The novel calculation formula and the decision tree effectively predict the clinical outcome of ciclosporin treatment for severe ulcerative colitis as early as on day 3 after starting ciclosporin treatment.

Abstract
The relationships between metabolic risk factors and abdominal fat distribution determined using computed tomography (CT) are poorly defined in large populations. We investigated the cutoff values of the visceral fat area (VFA) to detect subjects with multiple risk factors of metabolic syndrome (MS) by sex and age groups, and attempted to examine whether sex- and age-specific cutoff values are needed. The subjects of this study were 11,561 Japanese men and women who participated in the Hitachi Health Study, received CT examination, and answered questionnaires on lifestyles between 2004 and 2009. VFA and waist circumference were measured using CT. The VFA cutoff values yielding an 80% sensitivity for the detection of multiple risk factors of MS were typically smaller among men under the age of 40 years (<40 years vs. ≥40 years; 86.4 cm(2) vs. 103.9 cm(2)). The area under the receiver operator characteristic curve of VFA for the detection tended to decrease according to age (P = 0.056 and P = 0.020 for trends in men and women). Age- and sex-specific cutoff values are needed. The sensitivity of the subjects under the age of 40 years is relatively smaller (70.0% for men and 60.0% for women) compare to other age groups when the same cutoff value is used regardless of age (e.g., cutoff value calculated to correspond to 80% sensitivity for subjects of all ages). Therefore, a smaller VFA cutoff point should be used among men under the age of 40 years.

Abstract
OBJECTIVE To examine the relationship between short sleep duration and body mass index (BMI), waist circumference (WC), visceral fat area (VFA) and subcutaneous fat area (SFA) among a working population in Japan. DESIGN Health-center-based, cross-sectional study. SUBJECTS The study subjects included 5400 men and 642 women aged 30 to 75 years who underwent an abdominal computed tomography (CT) scanning examination in a comprehensive health checkup. MEASUREMENTS Height and weight were measured, and BMI was calculated. WC, VFA and SFA were measured using a CT scanner. Sleep duration was self-reported. Analysis of covariance was used to estimate adjusted means of BMI, WC, VFA and SFA across categories of sleep duration with adjustments for potential confounders. Trend of the association was assessed using multiple linear regression analysis. RESULTS In men, the mean values of BMI, WC and SFA decreased with increasing sleep duration after adjustment for age, physical activity, smoking and drinking (P-value for trend <0.001). Additional adjustment for physical illnesses did not attenuate the explanatory power of the models (P-value for trend <0.001). In addition, the association between sleep duration and SFA did not change after controlling for VFA (P-value for trend <0.001). The mean values of SFA for subjects sleeping '<5 h', '5 to <6 h', '6 to <7 h' and '7 h' per day were 145.8±67.4 cm(2), 138.7±61.5 cm(2), 134.7±60.4 cm(2) and 132.5±49.2 cm(2), respectively. Sleep duration was not appreciably associated with VFA. In women, no significant association was detected in any models. CONCLUSION Shorter sleep duration is associated with higher BMI, WC and SFA in men. Further research is needed to explicate the biological mechanisms behind these relationships and to see whether interventions addressing inadequate sleep could treat or prevent obesity by taking gender differences into consideration.

Abstract
Increasing evidence suggests that diverse solid tumours arise from a small population of cells known as cancer stem cells or tumour-initiating cells. Cancer stem cells in several solid tumours are enriched for aldehyde dehydrogenase (ALDH) activity. High levels of ALDH activity (ALDH(high)) were detected in four cell lines derived from canine mammary carcinomas. ALDH(high) cells were enriched in a CD44(+)CD24(-) population having self-renewal capacity. Xenotransplantation into immunodeficient mice demonstrated that 1×10(4) ALDH(high) cells were sufficient for tumour formation in all injected mice, whereas 1×10(4) ALDH(low) cells failed to initiate any tumours. ALDH(high)-derived tumours contained both ALDH(+) and ALDH(-) cells, indicating that these cells had cancer stem cell-like properties.

Abstract
A highly charged uranium (U) ion beam is produced from the RIKEN superconducting electron cyclotron resonance ion source using 18 and 28 GHz microwaves. The sputtering method is used to produce this U ion beam. The beam intensity is strongly dependent on the rod position and sputtering voltage. We observe that the emittance of U(35+) for 28 GHz microwaves is almost the same as that for 18 GHz microwaves. It seems that the beam intensity of U ions produced using 28 GHz microwaves is higher than that produced using 18 GHz microwaves at the same Radio Frequency (RF) power.

Abstract
We measured the beam intensity of highly charged heavy ions and x-ray heat load for RIKEN superconducting electron cyclotron resonance ion source with 28 GHz microwaves under the various conditions. The beam intensity of Xe(20+) became maximum at B(min) ∼ 0.65 T, which was ∼65% of the magnetic field strength of electron cyclotron resonance (B(ECR)) for 28 GHz microwaves. We observed that the heat load of x-ray increased with decreasing gas pressure and field gradient at resonance zone. It seems that the beam intensity of highly charged heavy ions with 28 GHz is higher than that with 18 GHz at same RF power.

Abstract
To determine the influence of the transplantation site of canine osteosarcoma (OS) cell lines on tumour growth and pulmonary metastasis, three OS cell lines were transplanted into nude mice via subcutaneous (SC), intratibial (IT) or intravenous (IV) injection. IT-xenografts exhibited greater potential for developing primary masses and pulmonary metastasis than SC-xenografts. In IT and IV xenografts, lung micrometastases along with phosphorylated ezrin-radixin-moesin (p-ERM) overexpression were found in mice xenografted with HMPOS and OOS cells after 1 week and metastasis was found with decreased p-ERM expression at later time points. The expression of ezrin and p-ERM in the primary tumours of IT-xenografted mice was higher than those in SC-xenografted mice with HMPOS and OOS cells. The results suggest that the orthotopic transplantation site plays an important role in the spontaneous metastasis of canine OS and that ezrin phosphorylation may be involved in the early metastatic mechanism of canine OS cells.

Ototoxicity of Povidone-Iodine applied to the middle ear cavity of guinea pigs. Int J Pediatr Otorhinolaryngol 2011; 75:1078-81. [PMID: 21741096 DOI: 10.1016/j.ijporl.2011.05.013] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/10/2011] [Revised: 05/11/2011] [Accepted: 05/12/2011] [Indexed: 02/01/2023]
Abstract
OBJECTIVE Povidone-Iodine preparation is used as a disinfectant in otological surgeries. The ototoxicity of Povidone-Iodine preparation was evaluated using infant, young and adult guinea pigs. The effects of different concentrations and of different exposure durations on compound action potentials were also studied. MATERIALS & METHODS Povidone-Iodine was used to fill one middle ear cavity of the guinea pig, and the compound action potential (CAP) was measured from the round window membrane at 24h, 7 days, and 28 days. The contralateral side was filled with saline as control. Test sounds used were clicks and tone bursts of 2, 4, and 8 kHz. RESULTS At 24h, Povidone-Iodine solution showed a significant toxic effect in the infant group. In the young animal group, no toxic effect was seen. In the adult group, a mild degree of deafness for 2 kHz was found. At 7 days, the young group showed significant hearing loss for all frequencies, but the adult group did not show any hearing loss. With a half strength solution, both young and adult group did not show hearing loss. At 28 days, with a full strength solution, hearing loss became prominent for all sound stimulation. With 1/8th dilution, the young group showed a moderate hearing loss, but the adult group did not. CONCLUSION The thicker round window membrane in human is expected to provide more protection to the human cochlea than in the guinea pig model that we have studied. Mild hearing loss at 24h and 7 days using 10% solution, but no hearing loss with 5% solution at 7 days may indicate that rinsing of the middle ear cavity with saline during surgery should minimize the ototoxic effect of this product. The age of the animals does influence the outcome of the ototoxicity experiment. From this experiment, Povidone-Iodine preparations in the infant should be used with caution. Povidone scrub should not be used for otologic surgery.

Urinary concentrations of 15-epimer of lipoxin A(4) are lower in patients with aspirin-intolerant compared with aspirin-tolerant asthma. Clin Exp Allergy 2011; 41:1711-8. [PMID: 22093074 DOI: 10.1111/j.1365-2222.2011.03839.x] [Citation(s) in RCA: 41] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2011] [Revised: 05/05/2011] [Accepted: 06/22/2011] [Indexed: 01/25/2023]
Abstract
BACKGROUND Although an abnormality in arachidonic acid metabolism may be responsible for aspirin-intolerant asthma (AIA), there is little knowledge about the concentrations of urinary lipoxin A(4) (LXA(4)) and the 15-epimer of LXA(4) (15-epi-LXA(4)) in relation to asthma severity in AIA subjects. OBJECTIVE The purpose of this study is to estimate urinary LXA(4) and the 15-epimer concentrations to investigate lipoxins in AIA. METHODS In this study, we examined AIA, aspirin-tolerant asthma (ATA) and healthy control groups. The AIA and ATA groups were subdivided into the severe asthma and non-severe asthma subgroups. Urinary LXA(4), 15-epi-LXA(4) and leukotriene E(4) (LTE(4) ) were quantified using enzyme immunoassay after separating these compounds using high-performance liquid chromatography. RESULTS The urinary LXA(4) concentration was significantly lower than the 15-epi-LXA(4) concentration in the asthmatic subjects. The AIA group showed significantly lower urinary 15-epi-LXA(4) (P < 0.01) and higher urinary LTE(4) concentrations (P < 0.05) than the ATA group. Comparison of 15-epi-LXA(4) concentrations between the severe asthmatic and non-severe asthmatic subjects in the AIA and ATA groups revealed that the decreased 15-epi-LXA(4) concentration may be related to aspirin intolerance, but not asthma severity. Receiver operator characteristic curves demonstrated that the concentration ratio of LTE(4) to 15-epi-LXA(4) was superior to 15-epi-LXA(4) concentration and LTE(4) concentration as a predictive factor for aspirin intolerance. CONCLUSIONS AND CLINICAL RELEVANCE We have demonstrated for the first time that urinary 15-epi-LXA(4) concentration is significantly higher than LXA(4) concentration in both the AIA and ATA groups. 15-Epi-LXA(4) concentration was significantly lower in the AIA group with an increased urinary LTE(4) concentration than in the ATA group. An imbalance between proinflammatory cysteinyl-leukotrienes and anti-inflammatory 15-epi-LXA(4) may be involved in AIA pathogenesis.

Abstract
AbstractExternal quantum efficiencies (EQEs) of electroluminescent devices based on porous silicon (PS) reported to date are still below the minimum requirements for practical applications such as display devices (1 %) and optical interconnection (10 %). Post-anodization anodic oxidation of PS to enhance the EQE of electroluminescence from devices based on a thin transparent indium tin oxide contact mounted on either porosified n+-type silicon or p+n+-type silicon has been investigated. Enhancement of EQE by more than 2 orders of magnitude has been achieved on our devices. CW EQE of 0.51% has been obtained by using a single anodically oxidized n+-type porous layer. The device based on the p+n+ substrate yielded a CW EQE of 1.1 %, with a power efficiency of 0.08%. It is the first time that EQE greater than 1% is obtained. Furthermore, anodically oxidized devices show better stability than non-oxidized devices. The anodic oxidation proceeds in such a way that it mainly decreases the size of nonconfined silicon in PS. The dramatic enhancement in EQE can therefore be explained by preferential reduction of leakage carrier flow through non-confined silicon.

Abstract
Two cases of congenital and acquired cholesteatoma in the petrous apex were operated on via the translabyriathine approach. The cholesteatoma was removed, leaving a part of the matrix membrane in both cases as the matrix membrane was difficult to remove. Spaces including the mastoid and middle ear after removal of cholesteatoma were obliterated with only fibrin glue in order to pneumatize the operated space after surgery. Cerebrospinal fluid (CSF) leakage from the internal auditory meatus was prevented using a tiny fascia. The spaces occupied by the cholesteatoma were clearly pneumatized within 6 months after surgery in both patients. The advantage of creating pneumatized spaces after removal of cholesteatoms in the petrous apex was discussed.

Abstract
ABSTRACTMagnetocaloric effect of nanocomposites composed of iron-oxide or iron-nitride grains dispersed in a silver matrix was studied by calculating magnetic entropy change ΔS induced by a change in applied magnetic field H. These nanocomposites were synthesized by the inert gas condensation technique and nitridation by heat treatment in an ammonia gas stream. Average sizes of the iron-containing grains were 10-35 nm. Magnetic phases in the materials were Fe3O4 or γ -Fe2O3 for the oxide-composites and γ-Fe4N or ε -Fe3N for the nitride-composites. Values of the ΔS were obtained by applying a thermodynamic Maxwell's relation, (∂S / ∂H)T = (∂M / ∂T)H, to data set of magnetization M measured at various temperatures T. They clearly indicated significant enhancement due to the nanostructure as predicted.

Abstract
A 42 kb region on human chromosome 9p21 encodes for three distinct tumor suppressors, p16(INK4A), p14(ARF) and p15(INK4B), and is altered in an estimated 30-40% of human tumors. The expression of the INK4A-ARF-INK4B gene cluster is silenced by polycomb during normal cell growth and is activated by oncogenic insults and during aging. How the polycomb is recruited to repress this gene cluster is unclear. Here, we show that expression of oncogenic Ras, which stimulates the expression of p15(INK4B) and p16(INK4A), but not p14(ARF), inhibits the expression of ANRIL (antisense non-coding RNA in the INK4 locus), a 3.8 kb-long non-coding RNA expressed in the opposite direction from INK4A-ARF-INK4B. We show that the p15(INK4B) locus is bound by SUZ12, a component of polycomb repression complex 2 (PRC2), and is H3K27-trimethylated. Notably, depletion of ANRIL disrupts the SUZ12 binding to the p15(INK4B) locus, increases the expression of p15(INK4B), but not p16(INK4A) or p14(ARF), and inhibits cellular proliferation. Finally, RNA immunoprecipitation demonstrates that ANRIL binds to SUZ12 in vivo. Collectively, these results suggest a model in which ANRIL binds to and recruits PRC2 to repress the expression of p15(INK4B) locus.

Abstract
The efficacy of the local application of recombinant human fibroblast growth factor-2 (FGF-2) in periodontal regeneration has been investigated. In this study, a randomized, double-blind, placebo-controlled clinical trial was conducted in 253 adult patients with periodontitis. Modified Widman periodontal surgery was performed, during which 200 µL of the investigational formulation containing 0% (vehicle alone), 0.2%, 0.3%, or 0.4% FGF-2 was administered to 2- or 3-walled vertical bone defects. Each dose of FGF-2 showed significant superiority over vehicle alone (p < 0.01) for the percentage of bone fill at 36 wks after administration, and the percentage peaked in the 0.3% FGF-2 group. No significant differences among groups were observed in clinical attachment regained, scoring approximately 2 mm. No clinical safety problems, including an abnormal increase in alveolar bone or ankylosis, were identified. These results strongly suggest that topical application of FGF-2 can be efficacious in the regeneration of human periodontal tissue that has been destroyed by periodontitis.

Abstract
The blood-brain barrier (BBB) not only impedes the influx of intravascular substances from blood to brain, but also promotes transport of substances from blood to brain or from brain to blood through several transport systems such as carrier-mediated transport, active efflux transport, and receptor-mediated transport systems. The multidrug resistance transporter P-glycoprotein (P-gp) is an ATP-dependent efflux pump and contributes to efflux of undesirable substances such as amyloid-beta:(Abeta) proteins from the brain into the blood as well as many drugs such as anti-cancer drugs. The inhibition of P-gp has favorable and unfavorable effects on living bodies. P-gp deficiency at the BBB induces the increase of Abeta:deposition in the brain of an Alzheimer disease mouse model. It is also known that the Abeta:deposition is inversely correlated with P-gp expression in the brains of elderly non-demented humans. However, the transient inhibition of P-gp by antidepressants enables medicines such as anti-cancer drugs to enter the brain. Concerning Abeta:clearance in the brain, the low-density lipoprotein receptor-related protein 1 (LRP1) is a major efflux transporter for Abeta, while the receptor for advanced glycation end products (RAGE) is a major influx transporter for Abeta:across the BBB. Dysfunction of the BBB with efflux and influx transporters may contribute to the pathogenesis of some degenerative neuronal disorders. This review will focus on several transporters and discuss how medicines pass the BBB to reach the brain parenchyma.
