Peripheral vascular disease Adriamycin in vitro (adjusted odds ration [AOR] 10.61), SIEA flap (AOR, 4.76) and delayed reconstruction (AOR, 1.42) were found to be statistically significant risk factors for flap thrombosis. Other comorbidities were not linked. While the overall rate of flap thrombosis in free flap breast reconstruction was relatively low (2.4%), Plastic Surgeons should be aware that patients with peripheral vascular disease and those undergoing free SIEA flap are at higher risk of flap thrombosis and

they should closely monitor flaps to increase the chance for early salvage. © 2014 Wiley Periodicals, Inc. Microsurgery 34:589–594, 2014. “
“The proximal peroneal artery perforator (PPAP) flap is a reliable, thin fasciocutaneous

flap. The purpose of this article was to report our experience with the use of free PPAP flaps for reconstruction of defects of the distal hand and foot. From November 2012 to September 2013, 9 patients received reconstruction with 10 free PPAP flaps. The defect locations included the big toe (2 cases), metatarsophalangeal joint (5 cases), dorsal finger (2 cases) and volar finger (1 case). Flaps were raised based on proximal peroneal perforator Selleckchem MI-503 vessels without sacrificing the peroneal artery. The first dorsal metatarsal artery (5 cases) and digital artery (5 cases) were dissected as recipient vessels. The flap sizes varied from 2.5 x 2 cm to 9 x 5 cm. All of flaps were survival after surgery. One flap suffered from venous thrombosis and was successfully

salvaged by performing a venous thrombectomy and vein graft. The donor sites were all primarily closed with minimal morbidities. Follow-up observations were conducted for 7 to 20 months, and all patients had good functional recovery with satisfying cosmetic results. Perforators arising from the peroneal artery in the proximal lateral leg can be used to design small, pliable fasciocutaneous flaps. Although the pedicle is short, the vessel diameter is Ribonuclease T1 adequate for microvascular anastomosis to the distal foot and hand recipient vessels. The free PPAP flap may be a good option for reconstructing distal hand and foot defects. © 2014 Wiley Periodicals, Inc. Microsurgery, 2014. “
“Soft tissue defects of the distal lower extremities are challenging. The purpose of this paper is to present our experiences with the free peroneal artery perforator flap for the reconstruction of soft tissue defects of the distal lower extremity. Nine free peroneal artery perforator flaps were used to reconstruct soft tissue defects of the lower extremities between April 2006 and October 2011. All flaps were used for distal leg and foot reconstruction. Peroneal artery perforator flaps ranged in size from 2 cm × 4 cm to 6 cm × 12 cm. The length of the vascular pedicle ranged from 2 to 6 cm.

Twenty-three (11.4%) of the ‘symptomatic’ and 13 (8.4%) of the ‘asymptomatic’ organisms were

subsequently identified Crizotinib clinical trial as Campylobacter cinaedi. Six (3.0%) of the ‘symptomatic’ and no ‘asymptomatic’ organisms were subsequently identified as Campylobacter fennelliae. A third organism, labelled simply CLO3 [currently Helicobacter sp. strain CLO3 (CCUG 14564)] has never been formally named. The Campylobacter genus underwent a reclassification in 1991, which moved the two organisms identified within these studies, C. cinaedi and C. fennelliae, into the Helicobacter genus, with their resultant names being H. cinaedi (CCUG 18818) and H. fennelliae (CCUG 18820) (Vandamme et al., 1991). An interesting DNA Damage inhibitor facet of the Totten study involved an investigation of asymptomatic men from whom clinical isolates of H. cinaedi were obtained and concurrently examined for the presence of rectal leucocytosis. The authors demonstrated that rectal leucocytosis was significantly more likely in this group than in those who were culture negative for the organism (P=0.002). This may indicate a separate subclinical disease state within the asymptomatic cohort. No pathology samples were taken within this study to correlate this finding directly with tissue inflammation. The HIV status of the men was not given; however, the first studies to identify HIV came just a year before the publication of

the first Seattle paper, and so this omission is historically understandable (Barre-Sinoussi et al., 1983; Gallo et al., 1983). The correlation of clinical disease with the

level of immunosuppression of the host would have given an interesting insight into the apparently inconsistent pathogenicity of these organisms if this had been available. The organisms isolated within this study have been utilized to initiate experimental gastrointestinal illness within a primate model as described above (Flores et al., 1990); however, histological changes in the gut were not a prominent feature of the resultant disease. With relation to Koch’s four postulates click here (Koch, 1884; Marshall, 1995), these two Helicobacter species have potentially fulfilled the second, third and fourth criteria, but their level of fulfillment of the first can be debated (as they were also isolated in asymptomatic men who could conceivably have subclinical, but histologically relevant colitis). Nevertheless, these organisms are the Helicobacter spp. that are closest to being identified as the causative pathogens of a human colitic disease. Helicobacter cinaedi has also been isolated from other humans including from diarrhoeal faecal samples (Tee et al., 1987) and the blood and/or stool of three children and two adult females (CCUG 15432, CCUG 19503, CCUG 19504, CCUG 20698, CCUG 17733) (Vandamme et al., 1990). Limited clinical information was presented in this latter study, but at least one of the paediatric strains was from a diarrhoeal child.

Therefore, early T-cell apoptosis observed during L monocytogene

Therefore, early T-cell apoptosis observed during L. monocytogenes infection appears to hamper bacterial clearance and strategies

to prevent lymphocyte apoptosis may be beneficial for therapy. In support of this notion, SCID and nude mice, which lack T cells, exhibit a severe increase in L. monocytogenes accumulating in the liver [35]. c-FLIP is known to inhibit death receptor-mediated apoptosis but not other cell death pathways [36]. Of note, lymphocytes were depleted upon L. monocytogenes infection in TNF-R1-deficient mice and lpr mice [37], suggesting that these two death receptors are not involved in L. monocytogenes-induced T-cell apoptosis. In contrast, TRAIL-deficient www.selleckchem.com/products/Metformin-hydrochloride(Glucophage).html mice show a similar phenotype as vavFLIPR mice with reduced splenocyte apoptosis and reduced bacterial load [38]. Therefore, c-FLIPR might be important for inhibiting TRAIL-mediated apoptosis during L. monocytogenes infection. Alternatively, TNF-R1 and CD95 but not TRAIL may exert redundant functions during pathogen-induced cell death. Regardless of which death receptor system is crucial during L. monocytogenes CH5424802 infection, approaches, which aim at increasing c-FLIP expression in T cells, will target all death receptor pathways and, thus, might be a promising

therapeutic option. Taken together, endogenous murine c-FLIPR is induced on the protein level upon lymphocyte activation. Strikingly, vavFLIPR mice show better control of L. monocytogenes infection than WT littermates. These data strongly suggest that c-FLIPR is the murine functional counterpart of human c-FLIPS, but differs from viral FLIP. c-FLIPR cDNA was cloned into the vector HS21/45 vav-hCD4 [18] using the SfiI and NotI (New England Biolabs, Ipswich, MA, USA) restriction sites. The transgenic construct was injected into B6C3F1 zygotes and positive mice were identified via PCR on tail biopsies with following primers specific for the SV40 poly A sequence: c-FLIP forward 5′-GCCTGAAGAACATCCACAGAATAG-3′, Poly A reverse 5′-CTCATCAATGTATCTTATCATGTC-3′.

Positive lines were identified PLEKHM2 and backcrossed for more than ten generations to C57BL/6 mice. Expression of the transgene was analyzed via RT PCR and immunoblot (see later). WT littermates were used as control animals. All of the animals were kept under pathogen-free conditions in the animal facilities of the Heinrich-Heine University, Duesseldorf, and the Helmholtz Centre for Infection Research, Braunschweig. C57BL/6 mice were purchased from Harlan Laboratories (Indianapolis, IN, USA) and Charles River (Wilmington, MA, USA). All breeding and experiments were performed in accordance with the guidelines of national and local authorities. Lymphoid organs (thymus, spleen, lymph nodes) were taken from sex-matched vavFLIPR mice and nontransgenic littermate controls. Single cell suspensions were prepared by filtering organ suspensions through a nylon mesh.

In this context,

de Boer et al. suggest a AZD1208 concentration regulatory role for muscle PVAT around nutrient arterioles that may signal to the vessel wall, both locally (paracrine) and downstream (vasocrine), through outside-to-inside signaling. Finally Judy Muller-Delp and colleagues [5] seek new friends, new foes, and new clinical directions within the aging microcirculation, and explore emerging evidence that the reactive oxygen species H2O2 and ONOO˙− function as important signaling molecules in the aging microvasculature. Although the vasoactive and signaling properties of these ROS have been well-documented, relatively little work has been performed to determine whether these molecules can compensate for an age-related decline in NO˙-mediated vasodilation. In particular, clinical studies have only Daporinad manufacturer begun to consider two important possibilities regarding the role of ROS in the loss and/or maintenance of endothelium-dependent vasodilatation that occurs with advancing age. Delp and colleagues explore the possibilities that tight regulation of the balance of ROS is more critical to preservation of endothelium-dependent function in the aged vasculature than the absolute levels of any specific molecule or enzyme and/or ROS act as

vasodilatory signaling molecules that compensate for an age-induced reduction in NO˙ signaling. However, while numerous studies have implicated a role for H2O2 in regulation of vascular resistance in humans and some such as that by Henriksson et al. [4] in this volume of Microcirculation Loperamide demonstrated a role for ROS in the skin, little is known regarding the effects of age on ROS signaling in the microcirculation

of humans in key organs such as peripheral muscle and the myocardium. One way to study the coronary microvasculature in vivo in humans is by studying refractory angina. Refractory angina is normally observed in patients with CAD who do not respond to anti-angina treatment such as nitrates. There are multiple mechanisms that could explain this nitrate intolerance and while it is assumed that, in some patients, adding extrinsic NO˙ to an oxidatively stressed microvasculature would increase ONOO˙− production resulting in a further decrease of NO˙ bioavailability, in the elderly patient’, adding extrinsic NO˙ could disrupt the “new” vascular redox status, limiting ONOO˙− as an NO˙ donor. Currently, these hypotheses are speculative, and there is ample opportunity for new studies investigating the role of NO˙ and ONOO˙− in the coronary and other microcirculatory beds both in healthy aging and in elderly patients where the effectiveness of therapeutic interventions relies upon comprehensive knowledge of the alterations in vascular control mechanisms that occur with advancing age.

To address this question, we examined the role of CR3−/− and CR4−

To address this question, we examined the role of CR3−/− and CR4−/− in experimental cerebral malaria (ECM). We found that both CR3−/− and CR4−/− mice were fully susceptible to ECM and developed disease comparable to wild-type mice. Our results indicate that CR3 and CR4 are not critical to the pathogenesis of ECM despite their role in elimination of complement-opsonized pathogens. These findings support recent studies indicating the importance of the terminal complement pathway and the membrane

attack complex in ECM pathogenesis. Of the complement C3 receptors, Selleck CHIR-99021 only the complement receptor 1 (CR1, CD35) has an established role in the pathophysiology of malaria. CR1 serves as a host erythrocyte receptor for Plasmodium falciparum through its binding to PfRh4 (1–3), and polymorphic variants of CR1 associate with susceptibility to, and/or resistance to, severe malaria and cerebral malaria Fulvestrant supplier (CM) (reviewed in (4)). By contrast, the remaining complement C3 receptors, CR2, CR3 and CR4, have poorly defined roles in the development and progression of malaria infection and CM. Based on in vitro studies, C3dg, the ligand for CR2, is generated in

large amounts and deposited on red blood cells in an alternative pathway-specific mechanism in murine malaria infections (5). The relevance of this observation to human CM remains unclear, especially in the light of studies demonstrating that coupling of C3d to malaria antigens in murine vaccine studies does not provide enhanced immunogenicity (6–8). The remaining two receptors, CR3

and CR4, are well known for their role in the phagocytosis of iC3b-opsonized pathogens (reviewed in (9–11)). However, the contribution of CR3 and CR4 to parasite killing and/or clearance via phagocytosis in both human and murine uncomplicated malaria and in CM is not known. Complement receptor 3 (a.k.a., αMβ2, CD11b/CD18) and CR4 (a.k.a., αXβ2, CD11c/CD18) are members Aprepitant of the β2-integrin family of adhesion molecules that play important roles in tissue-specific homing of leucocytes during inflammation, leucocyte activation in the immune response, and phagocytosis (12–14). Both receptors bind multiple ligands and are widely expressed on all leucocytes (15), including neutrophils and macrophages that aid in clearance of malaria parasites and dendritic cells, which process antigen after ingesting parasite-infected red blood cells. The extent to which CR3 and CR4 contribute to these essential immune functions during malaria has received little attention. Instead, CR3 and CR4 are primarily used as cell surface markers to distinguish between myeloid subsets or followed for changes in expression during the course of malaria infection (16–20). Treatment with anti-CR3 antibody reportedly had no effect on the course of experimental cerebral malaria (ECM) (21,22). However, technical limitations of blocking antibody experiments require cautious interpretation as many variables affect experimental outcome (e.g.

Although viability of progeny and effective recombination could n

Although viability of progeny and effective recombination could not be established, it may be hypothesized that arrhizus and delemar represent a single biological species. The apparent phylogenetic and physiological separation of the lineages this website then would deserve the status of varieties at most. The varieties are similar in ecology and pathogenicity. The species Rhizopus arrhizus[14] was described 3 years prior to R. oryzae.[21] Fischer’s description is short, lacks figures, and no type material

is known to exist. In contrast, the description of R. oryzae by Went & Prinsen Geerligs [27] is comprehensive, includes figures, and the strain CBS 112.07 was deposited in the CBS reference collection by Went in 1907 as type strain of Rhizopus oryzae. Consequently, the name R. oryzae was preferred over R. arrhizus by numerous authors.[15, 32, 33] A further reason of the unpopularity of the name arrhizus was that Fischer [14] described the columella of R. arrhizus as subglobose PD-0332991 supplier to applanate, which was considered to be unusual for this species.[15] For the combined reasons mentioned above, Schipper [15]

treated R. arrhizus as a doubtful species. Ellis et al. [16] took up the name R. arrhizus again by designating NRRL 1469 as ex-neotype strain of R. arrhizus. This action is as legitimate as Schipper’s [15] decision, so that the species today has two nomenclaturally valid names, sanctioned by different interpretations of the protologues. In their comprehensive morphological study on the genus Rhizopus, Zheng et al. [17] preferred the name R. arrhizus. In our opinion the description of R. arrhizus by Fischer [14] is conclusive. It contains all features that need to be known for a correct identification of the species whereby it may be noted that mucoralean fungi are more remote from each other than e.g. highly evolved ascomycetes, and generally allow morphological recognition at the species level by a limited number of key features. Sporangiophores were described as 0.5–2 mm long, sporangia 120–250 μm in diameter and rhizoids (designated in German as ‘Haftfüsschen’) short and less branched, a

feature that the author expressed in the name. Subglobose to applanate columellae were also described to be present in R. arrhizus by Hagem (1907, as Mucor arrhizus), Hanzawa (1912, for R. delemar), and Zheng et al. [17]. We agree with Paclitaxel molecular weight Ellis et al. [16] that the protologue is sufficiently clear to allow unambiguous indication of a neotype, NRRL 1469 and therefore favor the use of the name Rhizopus arrhizus over R. oryzae. Rhizopus arrhizus A.

Treatment with ONO significantly recovered the levels of matrix G

Treatment with ONO significantly recovered the levels of matrix Gla Protein and Fetuin-A suppressed by adenine-induced CKD, and suppressed the overexpression of RUNX2 in the VSMC of the thoracic aorta (immunohistochemistry). In addition, DHE expression, a marker of oxidative stress, ACP-196 was highly expressed in the VSMC of the thoracic aorta by adenine-induced CKD, and was significantly reduced by treatment with ONO. Conclusion: Taken together,

these results suggest the protective role of ONO on vascular calcification via regulating the factors involved in calcification and oxidative stress in the experimental CKD model.

But it has been still Rapamycin chemical structure unknown if spironolactone has an additional renoprotective effect. We therefore aimed to evaluate the changes of clinical biomarkers related to kidney as well as albuminuria to add spironolactone on conservative treatment with renin angiotensin system (RAS) blocking drugs. Methods: Forty-nine

Japanese patients with diabetic nephropathy and albuminuria (from 100 mg/gCr to 2000 mg/gCr) using RAS-blocking treatment were enrolled in prospective, randomized, open-labelled study. Patients were treated with additional spironolactone 25 mg once daily and matched control for 8 weeks. Results: Albuminuria CHIR-99021 datasheet was reduced by 33% (95%CI 22–54; P = 0.0002) during treatment with spironolactone. When adjusted by blood pressure and eGFR, treatment of spironolactone still showed significant effect on reduction of albuminuria (P < 0.004). There was a tendency to increase in serum aldosterone levels during the spironolactone treatment, but there was no additional impact on albuminuria by spironolactone treatment in patients with higher concentrations of aldosterone (P = 0.608). Spironolactone treatment induced significant decrease in urinary excretion of beta2-microglobulin, N-acetyl-beta-D-glucosaminidase and angiotensinogen by 2.3 ± 6.5 U/gCr, 1026.9 ± 3174.6 mg/gCr and 156.7 ± 466 mg/gCr compared to group C (P = 0.0304, 0.029 and 0.

6) Therefore, IL-21 may achieve its effect by activating target

6). Therefore, IL-21 may achieve its effect by activating target genes downstream of STAT1, this website STAT3 and STAT5 in the activated naive CD8+ T cells. Interleukin-21 is a pleiotropic cytokine that has a broad range

of activations on immune cells. The effect of IL-21 on the differentiation of Th subsets is beginning to be delineated. In vitro stimulation of naive CD4+ T cells under Th1- or Th2-polarized conditions showed no differences in the levels of IFN-γ or IL-4 in normal and IL-21R knockout mice,15 suggesting that IL-21 has no effects on the differentiation of Th1 and Th2 cells in mice. However, IL-17 production was significantly lower in CD4+ T cells from IL-21R knockout mice than in those from normal mice under Th17-polarized conditions, demonstrating that IL-21 exerts critical functions in Th17 cell development.3,7 Two recent papers have described an IL-22-producing helper T cell population that co-expresses the chemokine receptor CCR6 and the skin-homing receptors CCR4 and CCR10.16,17 These

cells are distinct from both Th17 cells and Th1 cells. However, the effect of IL-21 on the differentiation of IL-22-producing T cells is not clear. It has been shown that IL-21 up-regulates the expression of IL-22 mRNA in activated naive CD4+ T cells.3 Consistent with these results, we found that IL-21 induced Rapamycin in vivo IL-22 production in activated naive CD4+ T cells at protein level. Unexpectedly, we demonstrated that IL-21 also induced IL-22 production in activated naive CD8+ T cells and the frequency of IL-22-producing cells in CD8+ T cells was higher than in CD4+ T cells from CBMCs. Moreover, IL-21 did

not induce IL-17 production in CD8+ T cells. These data suggest that there are some differences between the induction of IL-22 and IL-17. A transcription factor that might be involved in IL-22 expression is the aryl hydrocarbon receptor. The aryl hydrocarbon receptor agonist substantially alters the balance of IL-22 versus IL-17-producing cells.16 In line with previous studies showing that TGF-β, 3-mercaptopyruvate sulfurtransferase the critical factor in the development of Th17 cells, inhibited IL-22 production in CD4+ T cells,3 we showed that the addition of TGF-β inhibited the production of IL-22 but induced IL-17 production in activated naive CD8+ T cells. Our results demonstrated that, compared with IL-23 (data not shown), IL-21 induced higher levels of IL-22 in activated naive CD8+ T cells. Interleukin-21 belongs to the common γc-signalling cytokine family that includes IL-2, IL-7 and IL-15. Here, we found that IL-21 but not IL-15 or IL-2 induced the differentiation of Tc22 cells by naive CD8+ T cells, clearly indicating that signals mediated by the common γc are not specific to enhance IL-22 production. We found that IL-21 induced IL-22 production in naive and memory CD8+ T cells. However, naive CD8+ T cells stimulated with IL-21 produced IL-22 production in greater folds than memory CD8+ T cells.

Under Th17 conditions, the binding of Mel-18 at the Ifng promoter

Under Th17 conditions, the binding of Mel-18 at the Ifng promoter was much lower than at the Il17a promoter (Fig. 4H). We did not notice changes in the binding activity of Mel-18 at Hoxa7 promoter in the presence or absence of Th17 polarizing cytokines (Fig. 4G). As with Mel-18, there were no significant changes see more in the expression levels of the mRNA or protein of Ezh2 if the restimulation was either in the presence of Th17 conditions or IL-12 (Fig. 5A and B). But in contrast to Mel-18, the binding activity of Ezh2 at the Il17a promoter was not decreased without cytokines (Fig. 5C). The binding of Ezh2 at the Rorc,

Ifng, Tbx21 and Hoxa7 promoters was also not significantly altered between the different conditions (Fig. 5D–G). Ezh2 was associated more strongly with the Il17a promoter than with the Ifng promoter (Fig. 5H), but the differences were smaller in comparison to the differential binding activity of Mel-18 at these promoters (Fig. 4H). To determine whether the signaling pathways downstream to TGF-β were sufficient to maintain the high level of the binding activity of Mel-18 at the Il17a promoter, Th17 cells were restimulated

without cytokines or in the presence of either TGF-β alone or combination of TGF-β, IL-6 and IL-23 (Fig. 6A). The binding of Mel-18 was only modestly decreased when the restimulation was in the presence Dorsomorphin of TGF-β alone than with the cytokine combination. When the cells were restimulated without cytokines, the binding was further reduced almost to the level of unstimulated cells (resting). These results show that TGF-β is required for the maintenance of the binding activity of Mel-18 at the Il17a promoter

beyond the early TCR-dependent stage. Nevertheless, the presence of TGF-β in the absence of TCR stimulation, as in the resting conditions, is insufficient to induce the binding activity of Mel-18 at the Il17a Resveratrol promoter. The binding activity of RORγt was correlated with this of Mel-18; RORγt was associated with the Il17a promoter when the Th17 cells were restimulated for 18 h in the presence of the Th17 polarizing cytokines but not in their absence (Fig. 6B). The decrease in the binding activity of RORγt may reflect the reduced expression of Rorc mRNA following restimulation without TGF-β (Fig. 3A). However, we did not recognize substantial changes in the expression levels of RORγt protein at this time point (Fig. 6C). Therefore, as early as 18 h following restimulation the recruitment of RORγt, and not its expression, is regulated by the polarizing cytokines.

Laboratory data revealed that our patient did not express donor-s

Laboratory data revealed that our patient did not express donor-specific antibody and the peritubular capillaries did not exhibit C4d immunoreactivity. Upon consideration of both histological and laboratory findings, we diagnosed acute vascular rejection of Banff 2007 class ACR IIA. We commenced 3-day sessions of intravenous steroid

pulse therapy twice weekly and adjusted the trough TAC level to 5–8 ng/mL by varying the TAC dose. We next performed an allograft biopsy and found no evidence of rejection (the S-Cr level was 2.7 mg/dL on April 1 2013). The present case report demonstrates the difficulties associated with management of TAC-based regimens in kidney transplant patients undergoing antituberculosis therapy. We also review the relevant literature. The proportion of selleck compound kidney allografts that is not rejected has improved dramatically in the era of the calcineurin inhibitor (CNI), but the use of such a strong immunosuppressant increases the risk of infection. Of the various possible infections, tuberculosis is particularly problematic because infection of transplant patients is associated with a higher incidence of mortality than noted click here in the general population. The same antituberculosis agents are recommended for use in both transplant patients and the general population.[1] Rifampicin (RFP) plays a key role in antituberculosis therapy, but the

trough CNI level requires close attention because it is frequently decreased by RFP use. A 29-year-old man was admitted to our hospital in June 2013 for a scheduled biopsy 1 year after primary kidney transplantation. He had been diagnosed with IgA nephropathy at the age of 17 years. He underwent peritoneal dialysis in June 2011. In June 2012, he received a live-donor kidney transplant from his father. The ABO blood types of donor and recipient were compatible, and the HLA alleles were haplo-identical. The standard complement-dependent cytotoxicity cross-match test was negative. Immunosuppressive therapy consisted of tacrolimus (TAC), mycophenolate

mofetil, methylprednisolone and basiliximab. The allograft exhibited excellent early function, associated with an S-Cr selleck kinase inhibitor level of 1.2 mg/dL. The 1 year protocol biopsy revealed no evidence of rejection. However, our patient was diagnosed with lung tuberculosis. The QFT was positive and the chest CT findings typical of tuberculosis. Standard therapy with antituberculosis agents, consisting of isoniazid (INH) 300 mg, rifampin (RFP) 450 mg, ethambutol (EB) 500 mg and pyrazinamide (PZA) 1500 mg daily, commenced on 9 June 2012. Despite increasing the TAC dose (512 mg, daily) and frequent monitoring of the serum TAC trough level, the serum TAC level decreased gradually from 3.1 ng/dL on 7 July 2012 to 1.6 ng/dL on 1 October 2012.
