Abstract
We examined the effect of PGE1 on the expression of plasminogen activator inhibitor-1 (PAI-1) mRNA induced by tumor necrosis factor-alpha (TNF-alpha) in human mesangial cells, because PAI-1 is one of major factors for the progression of glomerulosclerosis. The expression of PAI-1 mRNA was increased after stimulation with TNF-alpha, and it was diminished by pre-incubation with PGE1. Next, we examined the effect of PGE1 on the phosphorylation of mitogen activated protein kinase (MAPK) family and Akt. TNF-alpha activated the phosphorylation of p44/42 MAPK, p38 MAPK, SAPK/JNK and Akt in mesangial cells. PGE1 inhibited the TNF-alpha induced phosphorylation of SAPK/JNK and Akt, but not p44/42 MAPK and p38 MAPK. The TNF-alpha induced expression of PAI-1 mRNA was not affected by PD98059, an inhibitor of MEK, SB203580, an inhibitor of p38 MAPK, nor LY294002, an inhibitor of PI3 K. However, DMAP, an inhibitor of SAPK/JNK, inhibited the expression of PAI-1 mRNA, suggesting that the TNF-alpha induced expression of PAI-1 mRNA is regulated by the SAPK/JNK dependent pathway in human mesangial cells. By the incubation with H8, an inhibitor of PKA, the inhibitory effect of PGE1 on the expression of PAI-1 mRNA was abolished, suggesting that PGE1 inhibited the PAI-1 mRNA expression via the PKA pathway. Our results suggest that the inhibition of PAI-1 synthesis by PGE1 in human mesangial cells may have therapeutic implications for glomerulosclerosis such as occurs in diabetic nephropathy.

Abstract
OBJECTIVE The aim of this study was to determine how lipoprotein lipase (LPL) and hepatic triacylglycerol lipase (HTGL) activity relate to serum adiponectin levels. RESEARCH DESIGN AND METHODS Fifty-five hyperlipidemic Japanese men were recruited for this study. LPL and HTGL activity in post-heparin plasma (PHP) was measured using Triton X-100 emulsified-[14C] triolein. The remaining activity in the presence of 1M NaCl was defined as HTGL activity. Serum adiponectin levels were determined by an enzyme-linked immunosorbent assay system. RESULT LPL activity had a positive relationship with HDL2, but had no relation with HDL3, while HTGL had positive relationship with HDL3, but had no relationship with HDL2. LPL activity showed a positive relationship [r = 0.345, p = 0.010] to serum adiponectin levels, while and HTGL activity showed an inverse relationship [r = - 0.365 p = 0.006]. Multiple regression analysis with LPL and HTGL as dependent variables and age, BMI, serum adiponectin and the homeostasis model assessment of insulin resistance (HOMA-IR) as independent variables showed LPL and HTGL's association to adiponectin did not persist after adjustments for these covariants. However, the association of LPL activity to HOMA-IR was found to persist after adjustments of age, BMI, and serum adiponectin. CONCLUSIONS There was a co-linearity between insulin sensitivity and adiponectin as well as insulin sensitivity and LPL/HTGL activity.

Abstract
AIM The aim of this study was to investigate the renal structural properties in diabetic nephropathy. METHODS Flow-pressure and pressure-glomerular filtration rate (GFR) relationships were determined for maximally vasodilated kidneys at 10 (pre-diabetic stage) and 42 weeks of age (diabetic stage) in Otsuka Long-Evans Tokushima Fatty rats (OLETF), an animal model of type 2 diabetes mellitus, using age-matched Long-Evans Tokushima Otsuka rats (LETO) as non-diabetic controls (n = 9 of each age for each strain). Kidneys were then perfusion-fixed for histological analysis. RESULTS At 10 weeks of age, the slope of flow-pressure relationship (minimal renal vascular resistance, reflecting overall luminal dimensions of preglomerular and postglomerular vasculature) was steeper in OLETF than in LETO. In contrast, the threshold pressure for beginning filtration (preglomerular-to-postglomerular vascular resistance ratio) at pressure-GFR relationship did not differ between the two strains; however, the slope of the relationship (glomerular filtration capacity) was lower in OLETF than in LETO. Thus, in the kidneys of 10-week-old OLETF rats, vascular narrowing and impaired glomerular filtration capacity already existed with no abnormalities in preglomerular-to-postglomerular vascular resistance ratio. From the age of 10-42 weeks, the following results were obtained: (1) Minimal renal vascular resistance decreased in both strains, but it diminished markedly in OLETF. (2) The pressure for beginning filtration increased in LETO, but remained unchanged in OLETF. (3) Glomerular filtration capacity decreased to the similar extent in both strains. (4) Histologically, the vascular lumen and wall thickness increased in the interlobular arteries of both strains. However, vascular luminal widening was more pronounced in OLETF, resulting in the reduction in wall to lumen ratio. (5) Glomerular injuries and increased blood pressure occurred only in OLETF. CONCLUSION In conclusion, during progression from the prediabetic to diabetic stage of OLETF, the pre-existing vascular narrowing was markedly attenuated without the concomitant increase in preglomerular-to-postglomerular vascular resistance ratio. Combined with increased blood pressure, these renal structural alterations could lead to the elevation of intraglomerular pressure in OLETF.

Abstract
Alveolar type II (ATII) cell proliferation and differentiation are important mechanisms in repair following injury to the alveolar epithelium. KGF is a potent ATII cell mitogen, which has been demonstrated to be protective in a number of animal models of lung injury. We have assessed the effect of recombinant human KGF (rhKGF) and liposome-mediated KGF gene delivery in vivo and evaluated the potential of KGF as a therapy for acute lung injury in mice. rhKGF was administered intratracheally in male BALB/c mice to assess dose response and time course of proliferation. SP-B immunohistochemistry demonstrated significant increases in ATII cell numbers at all rhKGF doses compared with control animals and peaked 2 days following administration of 10 mg/kg rhKGF. Protein therapy in general is very expensive, and gene therapy has been suggested as a cheaper alternative for many protein replacement therapies. We evaluated the effect of topical and systemic liposome-mediated KGF-gene delivery on ATII cell proliferation. SP-B immunohistochemistry showed only modest increases in ATII cell numbers following gene delivery, and these approaches were therefore not believed to be capable of reaching therapeutic levels. The effect of rhKGF was evaluated in a murine model of OA-induced lung injury. This model was found to be associated with significant alveolar damage leading to severe impairment of gas exchange and lung compliance. Pretreatment with rhKGF 2 days before intravenous OA challenge resulted in significant improvements in PO2, PCO2, and lung compliance. This study suggests the feasibility of KGF as a therapy for acute lung injury.

Abstract
Two deep ice cores from central Greenland, drilled in the 1990s, have played a key role in climate reconstructions of the Northern Hemisphere, but the oldest sections of the cores were disturbed in chronology owing to ice folding near the bedrock. Here we present an undisturbed climate record from a North Greenland ice core, which extends back to 123,000 years before the present, within the last interglacial period. The oxygen isotopes in the ice imply that climate was stable during the last interglacial period, with temperatures 5 degrees C warmer than today. We find unexpectedly large temperature differences between our new record from northern Greenland and the undisturbed sections of the cores from central Greenland, suggesting that the extent of ice in the Northern Hemisphere modulated the latitudinal temperature gradients in Greenland. This record shows a slow decline in temperatures that marked the initiation of the last glacial period. Our record reveals a hitherto unrecognized warm period initiated by an abrupt climate warming about 115,000 years ago, before glacial conditions were fully developed. This event does not appear to have an immediate Antarctic counterpart, suggesting that the climate see-saw between the hemispheres (which dominated the last glacial period) was not operating at this time.

Abstract
DNA interstrand crosslinks (ICL) present a major threat to cell viability and genome integrity. In eukaryotic cells, the ICLs have been suggested to be repaired by a complex process involving Xpf/Ercc1-mediated endonucleolytic incision and homologous recombination (HR). However, the entire feature of the ICL tolerating mechanism is still poorly understood. Here we studied chromosome aberrations (CA) and sister chromatid exchanges (SCE) by the use of the crosslinking agent mitomycin C (MMC), in chicken DT40 cells with the HR genes disrupted by targeted replacement. The disruption of the Rad54, Rad51B, Rad51C, Rad51D, Xrcc2 and Xrcc3 genes resulted in a dramatic reduction of spontaneous and MMC-induced SCEs. Interestingly, while HR-deficient cells were hypersensitive to cell killing by MMC, MMC-induced CAs were also suppressed in the HR-deficient cells except for Rad51D-, Xrcc2- and Xrcc3-deficient cells. These observations indicate that DNA double strand breaks (DSB) at stalled replication forks and those arising as repair intermediates present strong signals to cell death but can be tolerated by the HR repair pathway, where Rad54, Rad51B and Rad51C have an initiative role and repair can be completed by their paralogs Rad51D, Xrcc2 and Xrcc3. The impairment of the HR pathway, which otherwise leads to cell death, may be somewhat substituted by an alternative mechanism such as the Mre11/Rad50/Nbs1 pathway, resulting in reduced frequencies of SCEs and CAs.

Abstract
AIMS To clarify the cellular differentiation of colorectal villous tumours in malignant transformation, compared with that of tubular tumours (tubular adenoma and adenocarcinoma arising in tubular adenoma). METHODS AND RESULTS Forty-nine cases of colorectal villous tumours [six cases of low-grade villous adenoma, 21 of high-grade villous adenoma (VA), nine of invasive carcinoma in villous adenoma (CIVA), and 13 of pure villous carcinoma (PVC)] and 46 cases of tubular tumours [14 cases of low-grade and 17 of high-grade tubular adenoma (TA), and 15 cases of carcinoma in tubular adenoma (CITA)] were selected for this study based on their expression patterns of CD10 (small intestinal brush border), MUC2 (intestinal goblet cell), and HGM (gastric foveolar epithelium). HGM was more frequently expressed in the adenomatous components of villous tumours (63%) than in those of tubular tumours (14%) (P < 0.05). CD10 expression of high-grade TAs (47%) and carcinomas arising in TA (60%) was significantly higher than that of villous tumours (0%) (P < 0.05). CONCLUSIONS There were significant differences in the phenotypic expression of adenoma and adenocarcinoma between villous and tubular tumours, respectively. Villous tumours have a pathway of malignant transformation different from that of tubular tumours. Because of biological differences, colorectal villous tumours should be distinguished from tubular neoplasia. The analysis of the phenotype of colorectal neoplasms is useful for the evaluation of tumour progression.

Abstract
The charge density distribution has been determined for a transition metal cyanide, RbMn[Fe(CN)(6)], by means of the maximum entropy-Rietveld method combined with the highly angularly resolved synchrotron radiation x-ray powder diffraction at SPring-8 BL02B2. We directly observed a charge transfer from the Mn site to the Fe site in the low-temperature phase. On the basis of a local density approximation calculation, we discuss the origin for the anisotropic bonding electron distribution around the Mn3+ ion in the low-temperature phase.

Abstract
A 68-year-old woman who had been diagnosed with sarcoidosis presented with acral lentiginous melanoma (Breslow's tumour thickness, 2.6 mm; Clark's level IV) on her right heel. She underwent surgery for excision of the primary tumour and sentinel lymph node biopsy. The two sentinel lymph nodes revealed numerous sarcoidal granulomas and small nests of metastatic melanoma cells in the subcapuslar lesions. She subsequently underwent ilio-inguinal lymph node dissection. Surprisingly, all of the nine dissected nodes were mostly replaced by sarcoidal granulomas and contained melanoma micrometastases.

Abstract
The relationship between charge and spin degrees of freedom in a geometrically frustrated system, AlV2-xCrxO4 spinel, is investigated. Upon Cr doping, the charge-ordered phase of AlV2O4 is rapidly suppressed and a charge-disordered phase grows up instead. It is found that the magnetic ground state is a spin-glass state dominated by geometrical frustration for both phases, but larger spin entropy remains down to low temperatures in the charge-ordered phase, possibly owing to its two-dimensional character.

Abstract
Association with Epstein-Barr virus (EBV) infection has been noted in various types of cutaneous lymphoproliferative disorders. We report a 57-year-old Japanese woman with T-cell lymphoma mimicking dermatomyositis that was associated with chronic active EBV infection. She presented with low-grade fever, bilateral erythematous swellings on the eyelids, and necrotic papules on the face. Serum creatine kinase levels were elevated and a diffuse reticular shadow was detected in both lung fields. The infiltrate of atypical lymphocytes found in skin and muscle, which contained EBV-encoded small nuclear RNA-1 and EBV, was also detected in the CD4+ peripheral blood cells. Treatment with prednisolone resolved her lesions with no relapse for 3 years, after which there was a recurrence in her left lung. Combination chemotherapy was not effective against the lung lesion and she died with multiple organ failure 2 months after the recurrence.
