Cofilin, a hypoxia‐regulated protein in murine lungs identified by 2DE: Role of the cytoskeletal protein cofilin in pulmonary hypertension

Chronic alveolar hypoxia induces vascular remodeling processes in the lung resulting in pulmonary hypertension (PH). However, the mechanisms underlying pulmonary remodeling processes are not fully resolved yet. To investigate functional changes occurring during hypoxia exposure we applied 2DE to compare protein expression in lungs from mice subjected to 3 h of alveolar hypoxia and those kept under normoxic conditions. Already after this short‐time period several proteins were significantly regulated. Subsequent analysis by MALDI‐MS identified cofilin as one of the most prominently upregulated proteins. The regulation was confirmed by western blotting and its cellular localization was determined by immunohisto‐ and immunocytochemistry. Interestingly, enhanced cofilin serine 3 phosphorylation was observed after short‐term and after chronic hypoxia‐induced PH in mice, in pulmonary arterial smooth muscle cells (PASMC) from monocrotaline‐induced PH in rats, in lungs of idiopathic pulmonary arterial hypertension patients and in hypoxic or platelet‐derived growth factor BB‐treated human PASMC. Furthermore, elevated cofilin phosphorylation was attenuated by curative treatment of monocrotaline‐induced PH in rats and hypoxia‐induced PH in mice with the PDGF‐BB receptor antagonist imatinib. In conclusion, short‐term hypoxic exposure induced prominent changes in lung protein regulation. These very early changes allowed us to identify potential triggers of PH. Thus, respective 2DE analysis can lead to the identification of new target proteins for the possible treatment of PH.

Tolerability of metronomic administration of lomustine in dogs with cancer.

BACKGROUND Metronomic chemotherapy with alkylating agents has been shown to suppress tumor angiogenesis and prevent tumor recurrence in some settings. The use of adjuvant lomustine (1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea) administered in a metronomic fashion has not been evaluated in dogs. HYPOTHESIS Oral metronomic administration of lomustine will be well tolerated in dogs with spontaneously occurring malignant neoplasms. ANIMALS Eighty-one dogs with naturally occurring primary or metastatic tumors received metronomic administration of lomustine. METHODS Dogs were enrolled prospectively after cytological or histological diagnosis of a tumor that was unresectable, incompletely resected, refractory to chemotherapy, or metastatic. Dogs received once daily lomustine (2.84 mg/m² PO). End points of the trial were clinical, hematologic, or biochemical evidence of toxicosis, tumor progression, or death. RESULTS Starting dosage (median) was 2.84 mg/m² PO daily and treatment duration was 98 days (median, range, 1-770 days). The drug was discontinued in 22 dogs because of toxicoses. Toxicoses occurred in 13 dogs with gastrointestinal toxicosis, 4 dogs with thrombocytopenia, 3 dogs with increased alanine transaminase, 1 dog with neutropenia, and 1 dog with progressive azotemia. Eight dogs developed some degree of azotemia during treatment. Hepatotoxicosis was observed at a median of 265 days in 11 dogs. Thrombocytopenia was identified at a median of 432 days of administration. CONCLUSIONS AND CLINICAL IMPORTANCE In dogs with metastatic or terminal neoplasms without renal compromise, metronomic administration of lomustine was well tolerated. This can provide a treatment strategy for dogs that do not have other standard-care treatment options, and warrants evaluation in primary therapy.
The Impact of Foreign Entry on Chinese Banks

Utilizing hand collected data concerning foreign ownership in the Chinese banking sector, we examine whether foreign ownership improves the efficiency of Chinese banks. Foreign banks tend to provide cooperation in retail banking rather than in corporate or private banking. We find no robust evidence of an improvement in the efficiency of an average bank that receives foreign strategic investments. However, the bank cost and profit efficiency significantly improve when foreign strategic investments provide retail banking and internal control assistance respectively to local banks. These findings suggest that foreign investment improves local bank efficiency when it transfers technologies that are lacking in local banks.
Defining mild cognitive impairment in Parkinson's disease

Our purpose was to characterize a state of mild cognitive impairment (MCI) in Parkinson's disease (PD) (PD‐MCI) that would be analogous to the MCI that is posited as a precursor of Alzheimer's disease (AD). We categorized 86 PD subjects in a brain bank population as either cognitively normal (PD‐CogNL), PD‐MCI using criteria that included a 1.5 standard deviation or greater deficit upon neuropsychological testing consistently across at least one cognitive domain without dementia, and PD dementia (PD‐D) using DSM‐IV criteria. Twenty‐one percent of our PD sample met criteria for PD‐MCI, 62% were PD‐CogNL, and 17% had PD‐D. The mean duration of PD and MMSE scores of the PD‐MCI group were intermediate and significantly different from both PD‐CogNL and PD‐D. The cognitive domain most frequently abnormal in PD‐MCI was frontal/executive dysfunction followed by amnestic deficit. Single domain PD‐MCI was more common than PD‐MCI involving multiple domains. We conclude that a stage of clinical cognitive impairment in PD exists between PD‐CogNL and PD‐D, and it may be defined by applying criteria similar to the MCI that is posited as a precursor of AD. Defining PD‐MCI offers an opportunity for further study of cognitive impairment in PD and targets for earlier therapeutic intervention. © 2007 Movement Disorder Society
Cytomegalovirus Infection- and Age-Dependent Changes in Human CD8+ T-Cell Cytokine Expression Patterns

ABSTRACT T cells are strongly affected by immune aging, a phenomenon that leads to increased susceptibility to infections and decreased vaccination efficacy in elderly individuals. Cytomegalovirus (CMV) infection induces vigorous T-cell immune responses in humans and is thought to be a driving force of immune aging. In the present study we analyzed CMV-induced quantitative and qualitative differences in the cytokine-expressing T-cell repertoire from individuals of different age groups after in vitro stimulation. The CMV pp65 peptide pool and the superantigen Staphylococcus enterotoxin B (SEB) induced higher proportions of CD8+ effector T cells expressing gamma interferon (IFN-γ), tumor necrosis factor alpha (TNF-α), and granulocyte-macrophage colony-stimulating factor in the oldest study group, while only SEB induced increased responses in the middle-aged study group. Notably, CMV-specific multiple cytokine expression patterns revealed higher proportions of IFN-γ- and TNF-α-coexpressing CD8+ T cells exclusively in the oldest study group. These qualitative differences were absent in SEB-induced CD8+ effector T cells, although quantitative differences were detected. We report age-dependent qualitative changes in CMV-specific CD8+ T-cell cytokine patterns which are biocandidate markers of immune exhaustion in elderly individuals.
Clinical and nerve conduction study correlation in patients of diabetic neuropathy.

AIMS AND OBJECTIVES 1) To study types of neuropathy in Type 2 diabetes. 2) To correlate clinical features of peripheral neuropathy with nerve conduction study in Type 2 diabetes. MATERIAL A total of 50 diabetics, whose onset of diabetes after the age of 30 years were studied from Dr. D. Y. Patil hospital and research centre. Type 2 Diabetes mellitus with symptom suggestive of peripheral neuropathy were studied and included. Chronic alcoholic, peripheral neuropathy due to any other known cause were excluded. METHOD OF COLLECTION OF DATA: History of symptoms like paraesthesia like tingling sensation, burning feet, hyperaesthesia, foot ulcer, history of weakness and gait abnormality was noted. Complete central nervous system examination was performed to look for signs such as diminished ankle jerk, diminished power. Sensory examination for loss of light touch, superficial pain, temperature sense, vibration and joint position was done. Nerve conduction studies were performed using Clarity Octopus NCV/EMG machine. Written and informed consent from patient were taken. RESULTS 1) 46 patients i.e. 92% presented with complaints of tingling sensation and 32 patients i.e. 64% had burning feet. 2) 29 patients i.e. 58% have diminished ankle jerk, 29 patients i.e. 58% have diminished or loss of vibration sense, in 21 patients i.e. 42% patients have diminished light touch and 20 patients i.e. 40% patients have loss of joint position senses. 3) NCV performed on 50 patients of diabetic neuropathy out of which all patients i.e. 100% had involvement of lower limb and only 24 patients i.e. 48% had involvement of upper limb also. 4) Involvement of tibial and sural nerve is more common i.e. 86% and 82% respectively. 5) 42 patients i.e. 84% found to have distal symmetrical polyneuropathy, 2 patients i.e. 4% had isolated tibial nerve involvement, 4 patients i.e. 8% had pure sensory sural nerve involvement, and only 1 patient each of isolated medial and plantar nerve involvement. CONCLUSION Distal symmetrical polyneuropathy is most common form of diabetic neuropathy. Involvement of tibial and sural nerve is more common in diabetic neuropathy.
Localization and quantification of muscle damage by magnetic resonance imaging following step exercise in young women

Eccentric exercise affects muscles differentially according to intensity, duration, and previous exposure to the specific exercise activity. We used T2‐weighted magnetic resonance imaging sequences to localize and quantify muscle damage following step exercise and to determine correlations between transverse relaxation time (T2) and other markers of muscle damage. Eight women performed two‐step exercise bouts (30 min) separated by 8 weeks. Blood samples, MR scans, measurements of muscle strength, and muscle soreness were obtained immediately before, after, and up to 9 days after each bout. Resting muscle T2 (40.3±0.6 ms) increased exclusively in m. Adductor magnus (AM) in the thigh performing eccentric contractions and peaked 3 days after bout 1 (73.5±9.7 ms, P<0.05). Plasma creatine kinase (CK) activity peaked on day 3 after bout 1 and correlated with T2 in AM (r=0.96, P<0.001). After bout 2 CK and T2 were almost unaffected. This indicates that T2‐weighted MRI can be applied to identify muscles from which enzymes are being released into the circulation.
Monoterpene Production in Redberry Juniper Foliage Following Fire

Abstract Prescribed fire is commonly used to initiate redberry juniper (Juniperus pinchotti Sudw.) suppression, and herbivory by goats presents a potentially effective mechanism to prolong the efficacy of the reclamation treatment. Monoterpenes in redberry juniper leaves serve as a barrier to effective herbivory, but fire has the potential to reduce this barrier through reversion of aboveground growth to juvenile tissue. Traditional optimal defense theory predicts that because of the assumed fitness value of vegetative regrowth, plant secondary chemicals will be higher in this tissue than mature growth. This study was designed to measure the monoterpene concentration and composition from redberry juniper foliage sampled from 3 different ages of plant tissue. Prescribed fire was used to create 3- and 11-month regrowth juniper foliage, and mature growth of juniper was sampled as a control. Total monoterpene levels were lowest in the 3-month regrowth (P = 0.018). Monoterpene concentration and composition was similar for the 11-month and mature foliage. Concentration of terpinen-4-ol (P = 0.001) and alpha-terpineol (P = 0.007), identified as particularly aversive monoterpenoids to goats, was lowest in the 3-month regrowth but increased to levels found in mature leaves by 11 months of age. There was a trend in changes in composition of total oil as relative concentrations of monoterpene hydrocarbons (α-pinene, β-pinene/sabinene) decreased and monoterpene alcohols and oxygenated monoterpenes increased. These results identify a short period of time following a burn during which monoterpene levels in regrowth are low. This suggests a period of vulnerability in plant biochemical defenses that has the potential to be utilized by strategic herbivory by goats for more effective juniper management.
The role of teachers in the decision making processes that relate to school financial management in the Pinetown district primary schools.

The promulgation into law of the South African Schools Act (SASA) in 1996 ushered a new era in South African school management and governance. Informed by a number of values such as accountability, transparency and participation that permeate the new South African Constitution, the SASA has decentralised certain powers to the local stakeholders at school level. It meant that teachers, principals, parents and learners (in high schools) can work together towards a common vision for the school. The School Governing Body was installed as the powerful legal structure. Teachers, as one of the important stakeholders, are represented in the SGB and can participate in school decision making processes. Teachers are important stakeholder because they are the ones who are at the critical level since they deal directly with the learners. Their participation inside and outside the SGB is important. Given the above background, a case study of two primary schools was conducted. The two schools were sampled using the convenience and purposive sampling methods. Semi-structured interviews and document analysis were used to gather data. Four teachers, two from each school were interviewed. Semi-structured interviews were deemed appropriate for this study because they give the researcher an opportunity to ask follow-up questions. This study documented teachers narratives about their experiences regarding their participation in the decision-making processes that relate to school financial management. Through teachers’ narratives, the factors that hindered or promoted their participation were also explored. The findings indicated that teacher participation in school financial decision making did exist in the case study schools but was minimal. Teacher participation seemed to be more confined to the operational decision such as making a list of classroom needs that should be part of the school budget. However, teachers were found not to be involved in strategic decisions where decisions on issues such as setting financial goals of the school were made. It was also found that, despite their minimal involvement, teachers were satisfied with the role that they were playing in the school financial decision making processes.
Human Herpesvirus 6 Infection After Allogeneic Stem Cell Transplantation: Incidence, Outcome, and Factors Associated With HHV-6 Reactivation

Background Human herpesvirus 6 (HHV-6) is susceptible to latency and reactivation in hematopoietic stem cell transplant (HSCT) recipients. We investigated the incidence of HHV-6 DNAemia and factors related to HHV-6 DNAemia and death after allogeneic stem cell transplantations. We also explored the relationship between HHV-6 viral load and the presence of clinical signs. Methods Data concerning age, sex, transplantation conditions, graft-versus-host disease (GVHD), treatments, clinical signs, outcome, HHV-6, and other infections were collected for a historical cohort of 390 HSCT performed between 1999 and 2008 in the Transplant Unit of Nancy University Hospital Center. Univariate analysis was used to evaluate influences between the different parameters. Results The study included 220 of the 390 allogeneic HSCTs. For the analyzed period, 44 patients (n=44/220, 20%) presented HHV-6 DNAemia in whole blood, including three integrated forms. Fifteen percent (7/41) of HHV-6–positive patients presented clinical signs not related to higher viral load (P=0.164). The factors associated with HHV-6 DNAemia were as follows: cord blood transplantation (P<0.001), conditioning regimen (P=0.030), acute GVHD (P=0.003), and the type of prophylactic treatment for GVHD (P=0.001). HHV-6 DNAemia was not significantly associated with cytomegalovirus infection (P=0.937). HHV-6 DNAemia was not associated with death (P=0.151). Conclusions HHV-6 DNAemia was not so frequent after allogeneic transplantation. Factors associated with HHV-6 DNAemia were similar to those for other infections. No abnormally high death rate was observed in the HHV-6 positive population. The presence of clinical signs did not appear to be statistically related to HHV-6 viral load.
Second Language Word Learning through Repetition and Imitation: Functional Networks as a Function of Learning Phase and Language Distance

Introduction and Aim: Repetition and imitation are among the oldest second language (L2) teaching approaches and are frequently used in the context of L2 learning and language therapy, despite some heavy criticism. Current neuroimaging techniques allow the neural mechanisms underlying repetition and imitation to be examined. This fMRI study examines the influence of verbal repetition and imitation on network configuration. Integration changes within and between the cognitive control and language networks were studied, in a pair of linguistically close languages (Spanish and French), and compared to our previous work on a distant language pair (Ghazi-Saidi et al., 2013). Methods: Twelve healthy native Spanish-speaking (L1) adults, and 12 healthy native Persian-speaking adults learned 130 new French (L2) words, through a computerized audiovisual repetition and imitation program. The program presented colored photos of objects. Participants were instructed to look at each photo and pronounce its name as closely as possible to the native template (imitate). Repetition was encouraged as many times as necessary to learn the object’s name; phonological cues were provided if necessary. Participants practiced for 15 min, over 30 days, and were tested while naming the same items during fMRI scanning, at week 1 (shallow learning phase) and week 4 (consolidation phase) of training. To compare this set of data with our previous work on Persian speakers, a similar data analysis plan including accuracy rates (AR), response times (RT), and functional integration values for the language and cognitive control network at each measure point was included, with further L1-L2 direct comparisons across the two populations. Results and Discussion: The evidence shows that learning L2 words through repetition induces neuroplasticity at the network level. Specifically, L2 word learners showed increased network integration after 3 weeks of training, with both close and distant language pairs. Moreover, higher network integration was observed in the learners with the close language pair, suggesting that repetition effects on network configuration vary as a function of task complexity.
Profiling signalling pathways in formalin‐fixed and paraffin‐embedded breast cancer tissues reveals cross‐talk between EGFR, HER2, HER3 and uPAR

In the last few years, new approaches and developments in patient‐tailored cancer therapies have raised the need to select, more precisely, those patients who will respond to personalized treatments. Therefore, the most efficient way for optimal therapy and patient selection is to provide a tumour‐specific protein network portrait prior to treatment. The aim of our study was to monitor protein networks in formalin‐fixed and paraffin‐embedded (FFPE) breast cancer tissues, with special emphasis on epidermal growth factor receptor 2 (HER2)‐mediated signalling pathways, to identify and validate new disease markers. For this purpose we used a recently developed technology to extract full‐length proteins from FFPE tissues and analysed 23 molecules involved in HER2‐related signalling by reverse phase protein microarray (RPPA) in a series of 106 FFPE breast cancer tissue samples. We found a significant correlation of HER2 with human epidermal growth factor receptor 3 (HER3/erbB3), epidermal growth factor receptor 1 (EGFR/HER1/erbB1) and urokinase plasminogen receptor (uPAR) in routinely used FFPE breast cancer tissues. Thus, targeting HER2, EGFR, HER3 and uPAR together may offer a more efficient treatment option for patients with breast cancer. J. Cell. Physiol. 227: 204–212, 2012. © 2011 Wiley Periodicals, Inc.
Chronic Ethanol Exposure Increases Cytochrome P‐450 and Decreases Activated in Blocked Unfolded Protein Response Gene Family Transcripts in Caenorhabditis elegans

Ethanol is a widely consumed and rapidly absorbed toxin. While the physiological effects of ethanol consumption are well known, the underlying biochemical and molecular changes at the gene expression level in whole animals remain obscure. We exposed the model organism Caenorhabditis elegans to 0.2 M ethanol from the embryo to L4 larva stage and assayed gene expression changes in whole animals using RNA‐Seq and quantitative real‐time PCR. We observed gene expression changes in 1122 genes (411 up, 711 down). Cytochrome P‐450 (CYP) gene family members (12 of 78) were upregulated, whereas activated in blocked unfolded protein response (ABU) (7 of 15) were downregulated. Other detoxification gene family members were also regulated including four glutathione‐S‐transferases and three flavin monooxygenases. The results presented show specific gene expression changes following chronic ethanol exposure in C. elegans that indicate both persistent upregulation of detoxification response genes and downregulation of endoplasmic reticulum stress pathway genes.
