“Purpose To determine the risk of iatrogenic damage to the extensor tendons and sensory nerves under a bridge plate along the second versus third metacarpal. Methods Using 6 paired find more (left right) cadaver forearms wrists and via a volar approach, we created a distal radius fracture with metaphyseal comminution. We then applied a dorsal distraction plate to either the second or third metacarpal. We next performed dorsal dissection of the hand and wrist over the zone of injury to determine the position of the plate relative to the extensor tendons and sensory nerves. Results The bridge plate on the third metacarpal entrapped tendons of the first and third compartment in all 6 specimens. When the plate was

applied to the second metacarpal there were no cases of tendon entrapment. There were no instances of nerve entrapment in plating to either the second or third metacarpal. Conclusions CT99021 Distraction plating has been proposed for use in the second and third metacarpals for unstable comminuted distal radius fractures. We recommend formal exposure of the extensor tendons over the zone of injury when applying a distraction bridge plate to the third metacarpal. Clinical relevance Plating to the second metacarpal decreases the risk of entrapment of extensor tendons compared with plating to the third metacarpal.

“Purpose To establish whether NSC80467, a novel fused naphthquinone imidazolium, has a similar spectrum of activity to the well-characterized “survivin suppressant” YM155 and to extend mechanistic studies for this structural class of agent.\n\nMethods NSC80467 and YM155 were analyzed in parallel using assays measuring viability, survivin suppression, inhibition of DNA/RNA/protein synthesis and the cellular response to DNA damage.\n\nResults GI(50) values generated for

both compounds in the NCI-60 screen yielded a correlation coefficient of 0.748, suggesting significant concordance. Both agents were also shown to inhibit protein expression of survivin [BIRC5]. COMPARE analysis identified DNA damaging agents chromomycin A3 and bisantrene HCl and one DNA-directed inhibitor of transcription, actinomycin D, as correlating with the activity of NSC80467 and YM155. Furthermore, both agents were shown to preferentially inhibit DNA, over RNA and protein synthesis. Thus, the ability of NSC80467 and YM155 to induce a DNA damage response was examined further. Treatment of PC3 cells with either agent resulted in dose-dependent induction of gamma H2AX and pKAP1, two markers of DNA damage. The concentrations of agent required to stimulate gamma H2AX were considerably lower than those required to inhibit survivin, implicating DNA damage as an initiating event.

While correlations should be interpreted cautiously, especially in the relatively small RHD group, poorer ipsilesional motor performance was associated with longer completion time in the RHD group, and poorer contralesional motor performance and greater aphasia were associated with less independence in the LHD group.\n\nConclusions: These findings demonstrate impaired meal preparation after LHD or RHD but greater impairment after LHD. Poorer meal preparation is associated with different cognitive and motor deficits in the 2 stroke Protein Tyrosine Kinase inhibitor groups.”
“Werner mesomelia is characterized by a sequence variation in the specific region (position 404) of the enhancer ZRS of SHH. The phenotype

comprises variable mesomelia, abnormalities Semaxanib of the thumb and great toe and supernumerary digits. We describe extensive variation in

limb phenotype in a large family and report on a novel sequence variation NG_009240.1: g.106737G bigger than T (traditional nomenclature: ZRS404G bigger than T) in the ZRS within the LMBR1 gene. The newly recognized clinical features in this family include small thenar eminence, sandal gap, broad first metatarsals, mesoaxial polydactyly, and postaxial polydactyly. We provide information on 12 affected family members. We review the literature on how a sequence variation in ZRS may cause such diverse phenotypes. (c) 2014 Wiley Periodicals, Inc.”
“The therapeutic value of Delta-9-tetrahydrocannabinol (Delta 9-THC) in the aftermath of trauma has recently raised interest. A prospective animal model for posttraumatic stress disorder was employed to assess the behavioral effects of a single dose of Delta 9-THC administered intraperitoneally following exposure to psychogenic stress. Animals were exposed to predator scent stress and treated 1 h later with Delta 9-THC (1,5 and 10 mg/kg) or vehicle. The outcome measures included behavior in an elevated plus-maze and acoustic startle response 1, 6 and 24 h or 7 days after exposure and freezing behavior upon exposure to a trauma

cue 5-Fluoracil mw on days. Pre-set.cut-off behavioral criteria classified exposed animals as those with “extreme,” “minimal” or “intermediate” (partial) response. Circulating corticosterone levels were assessed over 2 h after exposure with and without Delta 9-THC. The behavioral effects of a CB1 antagonist (AM251) administered systemically 1 h post exposure were evaluated. In the short term (1-6 h), 5 mg/kg of Delta 9-THC effectively attenuated anxiety-like behaviors. In the longer-term (7 days), it showed no effect in attenuating PTSD-like behavioral stress responses, or freezing response to trauma cue. Delta 9-THC significantly decreased corticosterone levels. In contrast, administration of AM251 (a CBI antagonist/inverse agonist) 1 h post exposure attenuated long-term behavioral stress responses through activation of the HPA-axis.

Interestingly,

butanol extracts of Scutellaria baicalensis Georgi significantly reduced the TGF-beta 1-mediated EMT of MCF10A cells. Further analysis revealed that baicalin and baicalein, the major flavones of these butanol extracts, inhibited TGF-beta 1-mediated EMT by reducing the expression level of the EMT-related transcription factor, Slug via the NF-KB pathway, and subsequently increased migration in MCF10A cells. Finally, both compounds reduced the TGF-beta 1-mediated EMT, anchorage-independent growth and cell migration of human breast cancer cells (MDA-MB-231 cells). Taken together, these results suggest that baicalin and baicalein of Scurellaria baicalensis Georgi may suppress the EMT of breast epithelial cells and the tumorigenic activity of breast cancer cells. Thus, these compounds could have potential as therapeutic or supplementary agents for the treatment of breast cancer. (C) 2015 Elsevier Inc. All rights reserved.”
“Gynura selleck chemicals llc bicolor DC., a traditional vegetable in Japan, is cultivated as Kinjisou and Suizenjina in Ishikawa and Kumamoto prefectures, ACY-241 respectively. The adaxial side of the leaves of G. bicolor grown in a field is green, and the abaxial side is reddish purple. It has been reported that these reddish purple

pigments are anthocyanins. Although we established a culture system of G. bicolor, the leaves of G. bicolor plants grown under our culture conditions showed green color on both sides of all leaves. We investigated the effects of phytohormones and chemical treatments on anthocyanin accumulation in cultured plants. Although anthocyanin

accumulation in the leaves was slightly stimulated, anthocyanins accumulation in the Poziotinib molecular weight roots of the cultured plant was induced remarkably by 25-50 mu M methyl jasmonate (MJ) treatment. This induction was affected by light irradiation and sucrose concentration in the culture medium. However, salicylic acid (SA) and 1-aminocyclopropane-1-carboxylic acid did not induce anthocyanin accumulation in roots. And then, combinations of MJ and SA or MJ and AgNO(3) did not stimulate the anthocyanin accumulation in the root as found in the case of treatment by MJ solely.”
“Williams KC, Burdo TH. HIV and SIV infection: the role of cellular restriction and immune responses in viral replication and pathogenesis. APMIS 2009; 117: 400-12.\n\nThe human immunodeficiency virus (HIV) and simian immunodeficiency virus (SIV) have a long biological history. Both viruses evolved from Africa and remnants of them can be found in the ‘fossil record’ of several species in which they are not endemic. SIV remains endemic in several species of monkeys in Africa where it does not cause immune deficiency. HIV and SIV actively replicate within humans and Asian non-human primates, despite cellular and genetic viral restriction factors and genes, and at times robust innate and adaptive immune responses.

\n\nConclusion: These results indicate that NCTD induced cytotoxicity in HepG2 cells by apoptosis, which is mediated through ROS generation and mitochondrial pathway.”
“Objective: To investigate the association of 12 single nucleotide polymorphisms (SNPs) in folate metabolic click here genes with congenital heart disease (CHD).\n\nMethods: A total of 160 children with CHD and

188 control children were enrolled. Twelve SNPs related to folate metabolism, including CBS-C699T, DHFR-c594+59del19, FOLH1-T1561C, CBS-C699T, DHFR-c594+59del19, GSTO1-C428T, MTHFD-G878A and -G1958A, MTHFR-C677T and -A1298C, MTR-A2756G, MTRR-A66G, NFE2L2-ins1+C11108T, RFC1-G80A, TCN2-C776T and TYMS-1494del6, were genotyped by SNaPShot genotyping technology and confirmed by Sanger sequencing.\n\nResults: There were two SNPs including NFE2L2-ins1+C11108T selleck chemical and GST01-C428T and two compound mutants for (MTHFD-G1958A, MTHFR-C677T and MTR-A2756G) and (MTHFD-G1958A, RFC1-G80A and MTR-A2756G), which might increase the risk of CHD, and DHFR-c594+59del19 might decrease the risk of CHD. The CT genotype of NFE2L2-ins1+C11108T, OR = 2.15 (95% CI = [1.07, 4.32], p<0.05). The CT+TT genotype of NFE2L2-ins1+C11108T, OR = 1.98 (95% CI = [1.00, 3.93], p<0.05). The TT genotype of GST01-C428T, OR = 3.49, (95CI% = [1.06, 11.5], p<0.05). The GG genotype

of DHFR-c594+59del19, OR = 0.46 (CI% = [0.24, 0.87], p<0.05). The AG+GG genotype of DHFR-c594+59del19, OR = 0.53 (CI% = [0.29, 0.96], p<0.05). The ratios of the two compound mutants for (MTHFD-G1958A, MTHFR-C677T and MTR-A2756G) and (MTHFD-G1958A, RFC1-G80A and MTR-A2756G) in CHD are higher than that

in control, p50.05 (OR = 2.968, 95% CI = [1.022, 8.613]).\n\nConclusions: The CT genotype of NFE2L2-ins1+C11108T Lonafarnib solubility dmso and the TT genotype of GST01-C428T are susceptible factors for CHD. The AG, GG and (AG+GG) genotypes of DHFR-c594+59del19 are protective genotypes for CHD. Compound mutants for (MTHFD-G1958A, MTHFR-C677T and MTR-A2756G) and (MTHFD-G1958A, RFC1-G80A and MTR-A2756G) may increase the risk of CHD.”
“Objective: To assess the worldwide availability of misoprostol. Documenting the extent of misoprostol use in obstetrics-gynecology is difficult because the drug typically is unregistered for such indications. Methods: Data for 2002-2007 on annual sales (measured in weight) to hospitals and retail pharmacies, plus manufacturer prices per 200-mu g misoprostol, were analyzed for medications containing misoprostol alone or combined with a nonsteroidal anti-inflammatory drug (NSAID); regional and country-specific trends were identified. Consumer prices per pill are documented for all formulations of registered medications. Results: Of the misoprostol sold worldwide, 70% was misoprostol-NSAID-combination drugs; of this. 91% was sold in North America and Western Europe. Asia sold the most misoprostol-only drugs; sales increased dramatically in Bangladesh (by 128%) and India (646%), where various low-price brands are sold.

Furthermore, the number of resorption pits on CPC was reduced in these cultures compared with immunomagnetically enriched monocytes and preparations without additional plastic adherence steps. Optimal results with regard to yield, LDN-193189 solubility dmso number

of multinucleated osteoclasts, activity of TRAP and CA II, and resorption of CPC were obtained by simple density gradient centrifugation. Conclusion: All examined monocyte preparation protocols were suitable for the generation of osteoclasts on both polystyrene and CPC. Highly purified monocytes are not mandatory to obtain functional osteoclasts for investigation of biomaterial resorption.”
“We explore the effect of fluorine doping on hydrophobicity of nanoporous Z-VAD-FMK datasheet silicon carbide-derived carbon (SiCDC), and investigate the underlying barriers for adsorption and diffusion Of water vapor and CO2 in the fluorinated and nonfluorinated structures: We develop atomistic models

of fluorine-doped SiCDC at three different levels of fluorination, based on a hybrid reverse Monte Carlo constructed model of SiCDC, and develop a novel fir-principles force field for the simulation of adsorption and transport of water and CO2 in the fluorine-doped carbon materials. We demonstrate an apparent dual effect of fluorination, showing that while fluorination generates more hydrophilic carbon surfaces, they actually act as

more hydrophobic structures due to enhanced energy barriers in the disordered network of micropoous carbon. While an increase in adsorption energy and in water uptake buy CFTRinh-172 is seen for fluorine-doped carbon, large internal free energy barriers as well as the results of MD Simulations demonstrate that the increased adsorption is kinetically limited and not experimentally observable on practical time scales. We show that an increase in apparent hydrophobicity due to fluorination is mediated by larger free energy barriers arising from stronger binding of fluid molecules inside the pore network, as opposed to repulsion or steric hindrance to the diffusion of molecules through narrow pore entries. For carbon dioxide, adsorption enthalpies and activation energy barriers are both decreased on fluorination, indicating weakened solid fluid binding energies in the fluorinated systems.

In accord with MDS criteria, 38% of this cohort demonstrated PD-MCI at baseline and 48% at follow-up. Of the 36 participants in the multiple-domain PD-MCI subtype at time-1, 9 (25%) demonstrated no PD-MCI at follow up. Analysis revealed that approximately 13% of the representative population would demonstrate abnormally low scores for GF120918 inhibitor 2 of the 9 tests used, thereby meeting MDS criteria for PD-MCI. Clinicians and researchers need to approach a single diagnosis (i.e., based on one assessment) of PD-MCI with considerable caution.”
“Background: The purpose of our study was to determine whether cervical preparation with laminaria tents would improve the procedure of second-

and third-trimester medical termination of pregnancy (TOP) in terms of duration of abortion and hospitalization.\n\nStudy: A retrospective comparative study of two historical periods of women undergoing second- and third-trimester medical TOP at a single tertiary care center from September 2004 to December 2006 was conducted. During Period A, patients LOXO-101 nmr received oral mifepristone and vaginal misoprostol, while during Period

B, laminaria tents were added. Main outcome measures included initiation-to-delivery (ITD) time induction-to-delivery interval and hospitalization time.\n\nResults: Of 186 eligible women, 174 were enrolled in the study: 91 patients during Period A and 93 patients during Period B. The ITD time was reduced during Period B compared to Period A (43.2 +/- 6.2 h and LBH589 mw 48.5 +/- 13.2 h, respectively; p=.001). Similarly, the induction-to-delivery interval was significantly shorter during Period B (7.5 h) compared to Period A (12.7 h; p=.001). A significant

reduction in total hospital stay was observed during Period B (3 days) versus Period A (4 days; p<.001).\n\nConclusion: Cervical preparation with laminaria tents significantly shortens the duration of medical TOP that uses mifepristone-misoprostol without adverse events or serious complications.

“Background The incidence of multiple basal cell carcinomas (BCCs) is not well documented.\n\nObjectives To calculate the cumulative risks, rates and risk factors for the development of subsequent histologically confirmed BCCs.\n\nMethods For this cohort study the Dutch nationwide network and registry of histopathology and cytopathology (PALGA) was used. The first 2483 patients diagnosed with a first histologically confirmed BCC in the year 2004 were followed for 5 years. Multifailure survival models were used to study whether gender or age affected the risk of developing subsequent tumours.\n\nResults During our observational period, the 2483 patients developed a total of 3793 histologically confirmed BCCs. The 5-year cumulative risk of developing one or more subsequent BCCs was 29.2%. Incidence rates were 25 318 per 100 000 person-years in the first 6 months after first BCC diagnosis, decreasing to 6953 per 100 000 person-years after 5 years of follow-up.

However, its effect on hepatitis B virus (HBV) replication is unknown. In this study, the HBV DNA levels in HuH7 cell culture supernatants were lowered successfully by using myriocin and it was found that the 50% inhibitory concentration of myriocin is approximately 5 mu M. Myriocin and/or pegylated interferon (PEG-IFN) were also administered to chimeric mice for 2 weeks and the effects of these compounds on HBV DNA levels were determined. Myriocin alone did not reduce effectively the HBV DNA levels, whereas PEG-IFN alone reduced the DNA levels to 1/10th of the control levels. The combination of myriocin with PEG-IFN reduced the HBV levels to about 1/1,000th

of the control levels and induced a 1.0 log reduction in the levels of the HBV surface antigen and core protein. This latter effect was not observed in the other treatment groups. MI-503 cost In conclusion, the combination of myriocin with PEG-IFN represses synergistically HBV replication in vivo without inducing hepatotoxicity. J. Med. Virol. 83:587-593, 2011.

“Drugs that kill tuberculosis more quickly could shorten chemotherapy significantly. In Escherichia

coli, a common mechanism of cell death by bactericidal antibiotics involves R406 the generation of highly reactive hydroxyl radicals via the Fenton reaction. Here we show that vitamin C, a compound known to drive the Fenton reaction, sterilizes cultures of drug-susceptible and drug-resistant Mycobacterium tuberculosis, the causative agent of tuberculosis. While M. tuberculosis is highly susceptible to killing by vitamin C, other Gram-positive and Gram-negative pathogens are not. The bactericidal activity of vitamin C against M. tuberculosis is dependent on CYT387 cost high ferrous ion levels and reactive oxygen species production, and causes a pleiotropic effect affecting several biological processes. This study enlightens the possible benefits of adding vitamin C to an anti-tuberculosis

regimen and suggests that the development of drugs that generate high oxidative burst could be of great use in tuberculosis treatment.”
“Purpose: Digital breast tomosynthesis (DBT) is a promising breast cancer screening tool that has already begun making inroads into clinical practice. However, there is ongoing debate over how to quantitatively evaluate and optimize these systems, because different definitions of image quality can lead to different optimal design strategies. Powerful and accurate tools are desired to extend our understanding of DBT system optimization and validate published design principles.\n\nMethods: The authors developed a virtual trial framework for task-specific DBT assessment that uses digital phantoms, open-source x-ray transport codes, and a projection-space, spatial-domain observer model for quantitative system evaluation.

This study demonstrates the unique and complementary roles for PNs and TCs in overcoming barriers to treatment adherence faced by underserved breast cancer patients.”
“The existence of a close relation between presynaptic inhibitory alpha(2)-adrenoceptor and mu-opioid receptor pathways is well established. Such interplay CA4P in vivo may occur during chronic conditions that give rise to neuroadaptive changes involving both receptor systems. The aim of this study was to examine the effect of chronic treatment with the tricyclic antidepressant drug, desipramine, on alpha(2)-adrenoceptors and mu-opioid receptors

in the guinea pig brain. Guinea pigs were treated with 10 mg/kg desipramine, injected i.p. for 21 days, every 24 h. The levels of expression of alpha(2)-adrenoceptors and L-opioid receptors, the G protein receptor regulatory kinase, GRK2/3 and signal transduction inhibitory G proteins in synaptosomes of the guinea pig hippocampus and cortex were evaluated

by immunoblotting. Quantitative analysis of alpha(2)-adrenoceptor and mu-opioid receptor mRNA levels has been carried out by competitive reverse transcriptase polymerase chain reaction. The expression levels of alpha(2)-adrenoceptors and mu-opioid receptors and the respective mRNAs were found unchanged in the cortex, after chronic desipramine treatment. In these experimental conditions alpha(2)-adrenoceptor and mu-opioid receptor levels decreased, www.selleckchem.com/products/hsp990-nvp-hsp990.html while the relevant transcripts increased, in the hippocampus. GRK2/3 levels remained unchanged and increased, respectively, in the cortex and the hippocampus, after JQ1 purchase chronic exposure to desipramine. In the same experimental conditions, G alpha(i1), G alpha(i2), G alpha(o), and G alpha(z) levels remained unchanged, while G alpha(i3) levels decreased, in the cortex; whereas, G alpha(i1), G alpha(i2) and G alpha(i3) levels significantly increased, and

G alpha(o) and G alpha(z) levels; remained unchanged, in the hippocampus. On the whole, the present data suggest that alpha(2)-adrenoceptor and mu-opioid receptor expression and transcription are similarly influenced by chronic treatment with desipramine, in the guinea pig cortex and hippocampus. Furthermore, alterations in the levels of regulatory GRK2/3 and of inhibitory signal transduction G proteins, relevant to activation of both receptor pathways, have been documented. The distinct pattern of adaptations of the different protein studied in response to chronic desipramine treatment in both regions is discussed. (C) 2007 Elsevier B.V. All rights reserved.”

“Myelination by oligodendroglial cells (OLs) enables the propagation of action potentials along neuronal axons, which is essential for rapid information flow in the central nervous system. Besides saltatory conduction, the myelin sheath also protects axons against inflammatory and oxidative insults. Loss of myelin results in axonal damage and ultimately neuronal loss in demyelinating disorders. However, accumulating evidence indicates that OLs also provide support to neurons via mechanisms beyond the insulating function of myelin. More importantly, an increasing volume of reports indicates defects of OLs in numerous neurodegenerative diseases, sometimes even preceding neuronal loss in pre-symptomatic episodes, suggesting that OL pathology may be an important mechanism contributing to the initiation and/or progression of neurodegeneration.

This review focuses on the emerging picture of neuronal support www.selleckchem.com/products/MLN8237.html by OLs in the pathogenesis of neurodegenerative disorders through diverse molecular and cellular mechanisms, including direct neuron-myelin interaction, metabolic support by OLs, and neurotrophic factors produced by and/or acting on OLs.”
“Purpose of review\n\nHuman cytomegalovirus (CMV) reactivation and disease remains one of the major complications after allogeneic haemopoietic stem cell transplantation. Cell-mediated immunity is essential in counteracting CMV infection as evident by detection of high frequencies of CMV-specific CD8(+) and CD4(+) lymphocytes among the healthy CMV-seropositive individuals. Adoptive transfer of

CMV-specific BEZ235 inhibitor T cells to speed up reconstitution of CMV-specific immunity potentially offers clinical protection and reduces drug toxicities as well as outgrowth of drug-resistant strains from prolonged antiviral therapy.\n\nRecent findings\n\nDifferent strategies to generate CMV-specific T cell have been explored. Similarly, vast diversities in term of cell dose and composition of the cellular product have been infused into small cohorts of patients. To date, a number of phase I/II clinical trials have demonstrated the feasibility of adoptive transferred CMV-specific T cells as prophylaxis, pre-emptive or therapeutic measure. In general, all these strategies showed variable degrees of efficacy without obvious adverse event particularly with regard to the induction of graft-versus-host disease.\n\nSummary\n\nIn this review, we would like to give a comprehensive synopsis regarding therapeutic application of CMV-specific T cells in fighting CMV infection.

Methods and results Patients were suitable for inclusion if they presented (i) an ACS that was successfully revascularized by manual thrombo-aspiration and (ii) a large residual thrombus on coronary angiography and initial FD-OCT analysis. These patients underwent a second procedure including FD-OCT analysis after several days of optimal antithrombotic therapy. Serial area measurements within the athero-thrombotic culprit lesion were performed to evaluate the selleckchem OCT-thrombus score, volume, and length. Sixteen patients (88% men/age = 59.3 +/-

4.1 years/94% STEMI) were included in the study. The mean delay between OCT analyses was 3.9 +/- 0.3 day. No adverse event was observed during this interval. We observed a reduction of thrombus burden between the two analyses, as assessed by the significant reductions in OCT-thrombus score (22.3 +/- 2.6 vs. 10.3 +/- 1.3, P smaller than 0.001), OCT-thrombus volume (9.6 +/- 2.3 see more vs. 3.6 +/- 0.9 mm(3), P = 0.003), and OCT-thrombus

length (11.1 +/- 1.4 vs. 7.4 +/- 0.8 mm, P = 0.01). The percentages of OCT-thrombus score and volume reduction were highly correlated with the inter-OCT analyses delay (respectively rho = 0.65 and rho = 0.84, P smaller than 0.01 for both). Conclusion FD-OCT assessment of thrombus volume in selected ACS patients is feasible, safe, and could allow clot regression monitoring in vivo.”
“Context.-Renal interstitial fibrosis and, to a lesser extent, sclerotic glomeruli correlate with poor renal function. However, not all nonfunctional glomeruli are sclerotic. Many or most glomeruli with periglomerular fibrosis, while retaining blood flow, probably do not filter; therefore, they may not contribute to renal function.\n\nObjective.-To examine the relationship of periglomerular fibrosis and the sum of globally sclerotic glomeruli and glomeruli with periglomerular fibrosis (GSG+PF) with interstitial fibrosis and renal function.\n\nDesign.-Native kidney biopsies from 177 patients with chronic

renal injury were assessed for interstitial fibrosis, glomerular sclerosis, Citarinostat inhibitor and GSG+PF. Renal biopsies with active or acute lesions were not included. The percentage of globally sclerotic glomeruli and GSG+PF was correlated with the degree of interstitial fibrosis and serum creatinine levels.\n\nResults.-The percentage of GSG+PF correlates better with the degree of interstitial fibrosis and renal function than does the percentage of globally sclerotic glomeruli alone. This appears particularly true in chronic renal diseases of patients without diabetes. The number of globally sclerotic glomeruli correlates better with interstitial fibrosis and renal function than does the sum of globally and segmentally sclerotic glomeruli.\n\nConclusions.
