    Balkan Endemic Nephropathy (BEN) is a disease of subtle onset and insidious progression that typically occurs between the 4th and 6th decade in long‐resident individuals in highly specific geographic locations of the Balkan region and affects 1 – 5% of the population. Though it does not follow typical Mendelian genetics, there is a familial pattern of occurrence. Although residents may live only a few kilometers apart, certain locations are highly affected while others close by, even as close as across the road, remain unscathed. Because of this geographic selectivity scientists have searched for an environmental cause. It is thought that exposure to the toxic plant Aristolochia clematitis is to blame. Genotoxic N‐heterocyclic or polycyclic aromatic containing coal water leachates entering cultivated soil and drinking water are also a possible cause due to the proximity and predictive power of endemic foci to coal deposits. Evidence for Ochratoxin A fungal poisoning also exists. High levels of phthalates have been measured in BEN‐endemic drinking water. BEN is a probably a multifactorial disease that may result from exposure through some of above‐mentioned environmental sources, with genetic factors contributing. This review will discuss recent research concerning the etiology, potential therapies for the treatment of nephropathy, and unexplored research directions for this chronic kidney disease.

    Ochratoxin A is a nephrotoxic fungal metabolite (mycotoxin) occurring in foodstuffs. The compound is causally associated with mycotoxic porcine nephropathy, a disease comparable with a human kidney disease, Balkan endemic nephropathy. A preliminary survey of home-produced foodstuffs in areas of Yugoslavia revealed that contamination with ochratoxin A is more frequent in an area where Balkan endemic nephropathy is prevalent (endemic area) than in area where this disease is absent. This indicates higher exposure to foodborn ochratoxin A in the endemic area. Thus further evidence is provided supporting the hypothesis that ochratoxin A is a disease determinant of Balkan endemic nephropathyk0 PMID:888703

    Balkan endemic nephropathy (BEN) is a familial chronic tubulointerstitial disease with insidious onset and slow progression to terminal renal failure. Evidence has accumulated that BEN is an environmentally induced disease. There are three actual theories attempting to explain the environmental cause of this disease: (1) the aristolochic acid hypothesis, which considers that the disease is produced by chronic intoxication with Aristolochia, (2) the mycotoxin hypothesis, which considers that BEN is produced by ochratoxin A, and (3) the Pliocene lignite hypothesis, which proposes that the disease is caused by long-term exposure to polycyclic aromatic hydrocarbons and other toxic organic compounds leaching into the well drinking water from low-rank coals in the vicinity to the endemic settlements. Moreover, it was suggested that BEN risk is influenced by inherited susceptibility. Therefore, it has been expected that molecular biological investigations will discover genetic markers of BEN and associated urothelial cancer, permitting early identification of susceptible individuals who may be at risk of exposure to the environmental agents. Since kidney pathophysiology is complex, gene expression analysis and highly throughput proteomic technology can identify candidate genes, proteins and molecule networks that eventually could play a role in BEN development. Investigation of gene-gene and gene-environment interactions could be the content of further studies determining the precise risk for BEN.

  4. Etiology of Balkan endemic nephropathy: A multifactorial disease?

    International Nuclear Information System (INIS)

    Balkan endemic nephropathy (BEN) is of great clinical importance in the restricted areas of Bulgaria, Rumania, Croatia, Serbia, Bosnia and Herzegovina. So far, studies on the etiological factors for BEN have not discovered any single environmental causative agent of this puzzling disease. These data reject the possibility of a purely environmental causation of BEN. The pattern of BEN transmission in the risk families is not typical for single gene disorders. Extensive epidemiological and genetic studies disclose characteristics of multifactorial (polygenic) inheritance of BEN. The evidences of 'familial tendency', variation of the risk for BEN depending on the number of sick parents and the degree of relatedness; the development of BEN in individuals from at-risk families who were born in non-endemic areas; the data that disease is not found in the gypsy population and the expressions of 3q25 cytogenetic marker suggest that the genetic factors play an important role as causative factors in BEN development. The possible impact of environmental triggers on individuals genetically predisposed to BEN could be supposed by the following data: the cytogenetic results of the increased frequency of folate sensitive Fra sites, spontaneous or radiation-induced aberrations in several bands in BEN patients, the data from the detailed analysis of breaks in BEN patients and controls that generate structural chromosome aberrations; the occurrence of BEN in immigrants. Genetical epidemiological approaches to etiology and prevention of BEN are proposed. The predisposing genes for BEN could be genes localized in a region between 3q25-3q26; transforming growth factor-β (TGF-β), genetic heterogeneity of xenobiotic-metabolizing enzymes; defects in the host's immune system. The predisposing genes for BEN patients with urinary tract tumors could be germline mutations in tumor suppressor genes and acquired somatic mutations in oncogenes

    Despite broad investigations into the possible role of genetic factors, environmental agents and immune mechanisms, the etiology of Balkan endemic nephropathy (BEN) is only partially understood. An increased incidence of upper urothelial cancer in patients with BEN and in populations from endemic settlements has been demonstrated. Genetic studies have landed support for genetic predisposition to BEN. The similarity of the morphological and clinical pattern of BEN and Chinese herbs nephropathy has raised the possibility of a common etiologic agent, aristolochic acid (AA), described in 1969 by Ivic and confirmed by a recent study of AA-DNA adducts. Ochratoxin A (OTA) is studied extensively as the etiologic agent of BEN. Weathering of low-rank coals nearby the endemic villages produces water-soluble polycyclic aromatic hydrocarbons and aromatic amines, similar to metabolic products of acetaminophen, which has a causal relationship with analgesic nephropathy. AA is confirmed as the etiologic agent of BEN; however, it may not be the sole risk factor. More research is needed on the patterns of BEN over time and between different endemic places. Therefore, it is important to test etiological hypotheses in different endemic foci, preferably as a multicentric research. An international approach to solving the etiology of BEN is needed in the coming years. The geographic correlation and presence of AA-DNA adducts in both BEN and associated urothelial cancer support the hypothesis that these diseases share a common etiology.

    Full Text Available Abstract Background Balkan Endemic Nephropathy (BEN is late-onset kidney disease thought to arise from chronic exposure to aristolochic acid, a phytotoxin that contaminates wheat supplies in rural areas of Eastern Europe. It has recently been demonstrated that humans are capable of perceiving aristolochic acid at concentrations below 40 nM as the result of high-affinity interactions with the TAS2R43 bitter taste receptor. Further, TAS2R43 harbors high-frequency loss-of-function mutations resulting in 50-fold variability in perception. This suggests that genetic variation in TAS2R43 might affect susceptibility to BEN, with individuals carrying functional forms of the receptor being protected by an ability to detect tainted foods. Methods To determine whether genetic variation in TAS2R43 predicts BEN susceptibility, we examined genotype-phenotype associations in a case–control study. A cohort of 88 affected and 99 control subjects from western Bulgaria were genotyped with respect to two key missense variants and a polymorphic whole-gene deletion of TAS2R43 (W35S, H212R, and wt/Δ, which are known to affect taste sensitivity to aristolochic acid. Tests for association between haplotypes and BEN status were then performed. Results Three major TAS2R43 haplotypes observed in previous studies (TAS2R43-W35/H212, -S35/R212 and –Δ were present at high frequencies (0.17, 0.36, and 0.47 respectively in our sample, and a significant association between genotype and BEN status was present (P = 0.020; odds ratio 1.18. However, contrary to expectation, BEN was positively associated with TAS2R43-W35/H212, a highly responsive allele previously shown to confer elevated bitter sensitivity to aristolochic acid, which should drive aversion but might also affect absorption, altering toxin activation. Conclusions Our findings are at strong odds with the prediction that carriers of functional alleles of TAS2R43 are protected from BEN by an ability to detect and

    Balkan endemic nephropathy (BEN) occurs in Serbia, Bulgaria, Romania, Bosnia and Herzegovina, and Croatia. BEN has been characterized as a chronic, slowly progressive renal disease of unknown etiology. In this study, we examined the influence of soluble organic compounds in drinking water leached from Pliocene lignite from BEN-endemic areas on plasma lecithin-cholesterol acyltransferase (LCAT) activity. We found that changes for all samples were the most prominent for the dilution category containing 90% plasma and 10% of diluting media. Water samples from BEN villages from Serbia and Romania showed higher LCAT inhibiting activity (P = 0.02) and (p = 0.003), respectively, compared to deionised water and non-endemic water. A secondary LCAT deficiency could result from this inhibitory effect of the organic compounds found in endemic water supplies and provide an ethiopathogenic basis for the development of BEN in the susceptible population.

  10. A possible link between Balkan endemic nephropathy and the leaching of toxic organic compounds from Pliocene lignite by groundwater: Preliminary investigation

    Balkan endemic nephropathy (BEN) is a fatal kidney disease that is known to occur only in clusters of villages in alluvial valleys of tributaries of the Danube River in Bulgaria, Romania, Yugoslavia, Bosnia, and Croatia. The confinement of this disease to a specific geographic area has led to speculation that an environmental factor may be involved in the etiology of BEN. Numerous environmental factors have been suggested as causative agents for producing BEN, including toxic metals in drinking water, metal deficiency in soils of BEN areas, and environmental mycotoxins to name a few. These hypotheses have either been disproved or have failed to conclusively demonstrate a connection to the etiology of BEN, or the clustering of BEN villages. In previous work, we observed a distinct geographic relationship between the distribution of Pliocene lignites in the Balkans and BEN villages. We hypothesized that the long-term consumption of well water containing toxic organic compounds derived from the leaching of nearby Pliocene lignites by groundwater was a primary factor in the etiology of BEN. In our current work, chemical analysis using 13C nuclear magnetic resonance (13CNMR) spectroscopy indicated a high degree of organic functionality in Pliocene lignite from the Balkans, and suggested that groundwater can readily leach organic matter from these coal beds. Semi-quantitative gas chromatography/mass spectroscopy analysis of solvent extracts of groundwater from shallow wells in BEN villages indicated the presence of potentially toxic aromatic compounds, such as napthalene, fluorene, phenanthrene, and pyrene at concentrations in the ppb range. Laboratory leaching of Balkan Pliocene lignites with distilled water yielded soluble organic matter (> 500 MW) containing large amounts of aromatic structures similar to the simple/discrete aromatic compounds detected in well water from BEN villages. These preliminary results are permissive of our hypothesis and suggest that further

    While to date investigations provided convincing evidence on the role of aristolochic acids (AAs) in the etiology of Balkan endemic nephropathy (BEN) and upper urothelial cancer (UUC), the exposure pathways by which AAs enter human bodies to cause BEN and UUC remain obscure. The goal of this study is to test the hypothesis that environmental pollution by AAs and root uptake of AAs in the polluted soil may be one of the pathways by which AAs enter the human food chain. The hypothesis driving this study was that the decay of Aristolochia clematitis L., a AA-containing herbaceous plant that is found growing widespread in the endemic regions, could release free AAs to the soil, which could be taken up by food crops growing nearby, thereby transferring this potent human nephrotoxin and carcinogen into their edible parts. Using the highly sensitive and selective high-performance liquid chromatography coupled with fluorescence detection method, we identified and quantitated in this study for the first time AAs in corn, wheat grain, and soil samples collected from the endemic village Kutles in Serbia. Our results provide the first direct evidence that food crops and soil in the Balkans are contaminated with AAs. It is possible that the presence of AAs in edible parts of crops originating from the AA-contaminated soil could be one of the major pathways by which humans become exposed to AAs. PMID:27362729

    Full Text Available Although recent data suggest aristolochic acid as a putative cause of Balkan endemic nephropathy (BEN, evidence also exists in favor of ochratoxin A (OTA exposure as risk factor for the disease. The potential role of xenobiotic metabolizing enzymes, such as the glutathione transferases (GSTs, in OTA biotransformation is based on OTA glutathione adducts (OTHQ-SG and OTB-SG in blood and urine of BEN patients. We aimed to analyze the association between common GSTA1, GSTM1, GSTT1, and GSTP1 polymorphisms and BEN susceptibility, and thereafter performed an in silico simulation of particular GST enzymes potentially involved in OTA transformations. GSTA1, GSTM1, GSTT1 and GSTP1 genotypes were determined in 207 BEN patients and 138 non-BEN healthy individuals from endemic regions by polymerase chain reaction (PCR. Molecular modeling in silico was performed for GSTA1 protein. Among the GST polymorphisms tested, only GSTA1 was significantly associated with a higher risk of BEN. Namely, carriers of the GSTA1*B gene variant, associated with lower transcriptional activation, were at a 1.6-fold higher BEN risk than those carrying the homozygous GSTA1*A/*A genotype (OR = 1.6; p = 0.037. In in silico modeling, we found four structures, two OTB-SG and two OTHQ-SG, bound in a GSTA1 monomer. We found that GSTA1 polymorphism was associated with increased risk of BEN, and suggested, according to the in silico simulation, that GSTA1-1 might be involved in catalyzing the formation of OTHQ-SG and OTB-SG conjugates.

    We use mitochondrial (mtCOI) and nuclear (nH3) sequence data to investigate differentiation of Eudiaptomus hadzici, a freshwater copepod endemic to the Western Balkans. E. hadzici has a disjunct distribution and morphological differences were observed at regional scale. In the current study 6 out of 7 known populations are included. We applied several species delimiting approaches, distance based methods (K2P p-distance and Automatic Barcode Gap Discovery, ABGD) using the mtCOI, Bayesian phylogeny and the Bayesian method implemented in bPTP and BPP programs using the concatenated sequences of both genes. Phylogenetic and species delimitation analyses all suggest that the nominal species E. hadzici consists of four isolated, cryptic evolutionary lineages in the Western Balkans. Each of the four lineages inhabits a single lake or a group of lakes in close proximity. They exhibit major differences in secondary sexual characters, e.g. right antennule in males. Denticulation of spine on 13th segment is substantially distinct among the four lineages, having different number and shape of tooth-like protrusions. Gene flow and dispersal are restricted to very small spatial scale, but with local differences, implying that diverse historical and contemporary processes are operating at small spatial scales in E. hadzici. In order to further examine spatial and temporal diversification patterns, we constructed a dated species tree analysis using (*)BEAST. Due to lack of reliable calibration points and taxa specific evolutionary rates, two evolutionary rates were applied and the faster one (2.6% myr) seems more plausible considering the geological history of the region. The divergence of E. hadzici lineages is dated from Early Miocene onwards with geographically close lineages diverging more recently, Late Miocene to Pleistocene and Pleistocene, respectively. Overall, our findings shed light on cryptic genetic complexity of endemics in one of European biodiversity hotspots

    Full Text Available Abstract Background The etiology of Balkan Endemic Nephropathy, (BEN, a tubulointerstitial kidney disease, is unknown. Although this disease is endemic in rural areas of Bosnia, Bulgaria, Croatia, Romania, and Serbia, similar manifestations are reported to occur in other regions, for instance Tunisia and Sri Lanka. A number of explanations have been stated including lignites, aristolochic acid, ochratoxin A, metals, and metalloids. Etiologic claims are often based on one or a few studies without sound scientific evidence. In this systematic study, we tested whether exposures to metals (cadmium and lead and metalloids (arsenic and selenium are related to Balkan Endemic Nephropathy. Methods In 2003/04 we recruited 102 adults whose parents had BEN and who resided in one of three communities (Vratza, Bistretz, or Beli Izvor, Bulgaria. A control group comprised of 99 adults having non-BEN hospitalized parents was enrolled in the study during the same time. We conducted face-to-face interviews, ultrasound kidney measurements, and determined kidney function in two consecutive investigations (2003/04 and 2004/05. Metals and metalloids were measured in urine and blood samples. To assess the agreement between these consecutive measurements, we calculated intraclass correlation coefficients. Repeated measurement data were analyzed using mixed models. Results We found that cadmium and arsenic were associated with neither kidney size nor function. Lead had a significant but negligible effect on creatinine clearance. Selenium showed a weak but significant negative association with two of the four kidney parameters, namely creatinine clearance and β2-microglobulin. It was positively related to kidney length. These associations were not restricted to the offspring of BEN patients. Adding credence to these findings are reports showing comparable kidney effects in animals exposed to selenium. Conclusion The findings of this 2-year follow-up study indicate that

The present study was undertaken with the aim to find out whether new persons with renal disorders can be detected among members of endemic families in the village of Šopić (Kolubara River region, Serbia. Methods. The study involved 44 members of five endemic families without history of renal disorders. Objective survey and laboratory analyzes that enabled determination of kidney functions (creatinine clearance, proteinuria, urine specific gravity and osmolality, fractional sodium excretion (FENa, the rate of tubular phosphate reabsorption (TRP, urine N-acetil-D-glycosaminidase and intestinal alkaline phosphatase were done in all examined persons three times during the 6-month intervals. Results. At the first examination, hypertension was detected in 23 (52% person, decreased creatinine clearance in two and proteinuria in 10 persons included in the study. In addition, proteinuria and tubular disorders were detected in 6, hypertension, proteinuria and/or tubular disorders in 9 persons. The analysis of the results obtained by three check-ups undertaken during one year showed that proteinuria and tubular disorders appeared intermittently in half of the examined endemic family members. All persons with detected renal disorders required further examination in order to establish accurate diagnosis of renal disease. Conclusion. Three check-ups performed at six-month intervals in the members of five endemic families detected various renal disorders including renal hypofunction. Regular systematic check-ups of endemic families could enable early detection of the disease and early initiation of measures for slowing down chronic renal disease progression.

    Full Text Available Despite many hypotheses that have been challenged, the etiology of endemic nephropathy (EN is still unknown. At present, the implications of aristolochic acid (AA and mycotoxins (ochratoxin A—OTA and citrinin—CIT are under debate. AA-theory is based on renal pathohistological similarities between Chinese herbs nephropathy (CHN and EN, findings of AA-DNA adducts in EN and in patients with urinary tract tumors (UTT, as well as the domination of A:T→T:A transversions in the p53 mutational spectrum of UTT patients, which corresponds with findings of such mutations in AA-treated rats. However, exposure pathways of EN residents to AA are unclear. Experimental studies attempting to deduce whether nephrotoxins OTA and CIT appear at higher frequencies or levels (or both in the food and blood or urine of EN residents support the mycotoxin theory. Also, some molecular studies revealed the presence of OTA-DNA adducts in the renal tissue of EN and UTT patients. In this review, data supporting or arguing against AA and mycotoxin theory are presented and discussed.

    Occupational exposure to heavy metals, organic solvents and silica is associated with a variety of renal manifestations. Improved understanding of occupational renal disease provides insight into environmental renal disease, improving knowledge of disease pathogenesis. Silica (SiO2) is an abundant mineral found in sand, rock, and soil. Workers exposed to silica include sandblasters, miners, quarry workers, masons, ceramic workers and glass manufacturers. New cases of silicosis per year have been estimated in the US to be 3600-7300. Exposure to silica has been associated with tubulointerstitial disease, immune-mediated multisystem disease, chronic kidney disease and end-stage renal disease. A rare syndrome of painful, nodular skin lesions has been described in dialysis patients with excessive levels of silicon. Balkan endemic nephropathy is postulated to be due to chronic intoxication with drinking water polluted by silicates released during soil erosion. The mechanism of silica nephrotoxicity is thought to be through direct nephrotoxicity, as well as silica-induced autoimmune diseases such as scleroderma and systemic lupus erythematosus. The renal histopathology varies from focal to crescentic and necrotizing glomerulonephritis with aneurysm formation suggestive of polyarteritis nodosa. The treatment for silica nephrotoxicity is non-specific and depends on the mechanism and stage of the disease. It is quite clear that further research is needed, particularly to elucidate the pathogenesis of silica nephropathy. Considering the importance of diagnosing exposure-related renal disease at early stages, it is imperative to obtain a thorough occupational history in all patients with renal disease, with particular emphasis on exposure to silica, heavy metals, and solvents.

    Toxic organic compounds can be leached from coal into water supplies, and long term human exposure to these compounds may lead to disease occurrence, including cancer and renal disease. Despite these potential hazards, little is known about the impact and toxicity of organic substances derived from coal in water supplies. One example of a disease hypothesized to be linked to coal-derived toxic organic compounds in water supplies is Balkan endemic nephropathy (BEN). This paper summarises results from studies linking BEN to the leaching of toxic organic compounds from low rank (lignite) Pliocene coal deposits into water supplies of the rural villages where the disease occurs. It introduces the idea of panendemic nephropathy (PEN) for BEN-like diseases that are linked to coal-derived toxic organic compounds in water supplies, but that occur outside outside the Balkans. Preliminary results supporting the PEN hypothesis are presented, with results from proposed PEN areas in Wyoming and Louisiana. Results of toxicological studies of the effects of organic compounds isolated from water supplies in BEN and PEN areas on human cell cultures are also discussed. China, India, Turkey and Portugal represent other areas where BEN-like diseases may occur, as a result of the presence of extensive low rank coal deposits and rural populations using untreated water in contact with coal in these nations. 31 refs., 2 figs.

    Karyomegalic nephropathy associated to bizarre enlargement of nuclei in renal tubular epithelial cells was first described by Mihatch in 1979. We present herein additional cases occurring in three siblings suffering from chronic interstitial nephropathy (CIN) of unknown aetiology where the renal biopsies showed numerous enlarged and hyperchromatic nuclei. CIN of unknown aetiology has been previously characterized and showed striking similarities with Balkan Endemic Nephropathy (BEN). Ochratoxin A (OTA) is a nephrotoxic mycotoxin suspected to be the causal agent of the BEN as well as the Tunisian CIN of unknown aetiology. OTA is incriminated in the onset of these disclosed cases of karyomegalic nephropathy since high OTA concentrations were found in blood (505.83 ng/ml, 102.63 ng/ml and 1023 ng/ml) and in urine (94.40 ng/ml and 10.18 ng/ml) of two of them. Moreover, we have investigated OTA in blood and urine as well as in food samples of the entire household (21 people). Our findings suggest (i) a link between OTA and the outcome of this karyomegalic nephropathy, and (ii) the possible involvement of a genetic factor since the three cases have the same haplotype B27/35.

    Full Text Available Abstract Diabetic nephropathy is the leading cause of chronic renal disease and a major cause of cardiovascular mortality. Diabetic nephropathy has been categorized into stages: microalbuminuria and macroalbuminuria. The cut-off values of micro- and macroalbuminuria are arbitrary and their values have been questioned. Subjects in the upper-normal range of albuminuria seem to be at high risk of progression to micro- or macroalbuminuria and they also had a higher blood pressure than normoalbuminuric subjects in the lower normoalbuminuria range. Diabetic nephropathy screening is made by measuring albumin in spot urine. If abnormal, it should be confirmed in two out three samples collected in a three to six-months interval. Additionally, it is recommended that glomerular filtration rate be routinely estimated for appropriate screening of nephropathy, because some patients present a decreased glomerular filtration rate when urine albumin values are in the normal range. The two main risk factors for diabetic nephropathy are hyperglycemia and arterial hypertension, but the genetic susceptibility in both type 1 and type 2 diabetes is of great importance. Other risk factors are smoking, dyslipidemia, proteinuria, glomerular hyperfiltration and dietary factors. Nephropathy is pathologically characterized in individuals with type 1 diabetes by thickening of glomerular and tubular basal membranes, with progressive mesangial expansion (diffuse or nodular leading to progressive reduction of glomerular filtration surface. Concurrent interstitial morphological alterations and hyalinization of afferent and efferent glomerular arterioles also occur. Podocytes abnormalities also appear to be involved in the glomerulosclerosis process. In patients with type 2 diabetes, renal lesions are heterogeneous and more complex than in individuals with type 1 diabetes. Treatment of diabetic nephropathy is based on a multiple risk factor approach, and the goal is retarding the

    Full Text Available New world order and rearrangement of Europe transform the position of Balkan region -instead as the "crossroad" between East and West, it is more often included into the area of Western influence. In European relations developed "core" is gradually spreading toward "periphery" removing the traditional Balkan culture. The europeisation of Balkans and spreading of Western European civilization's circle gives the arguments that the term Balkans should be replaced with the term Southeastern Europe. The europeisation or balkanization is not geopolitical but civilization choice in front of all Balkan nations.

  14. Molecular evidence for an involvement of organic anion transporters (OATs) in aristolochic acid nephropathy

    International Nuclear Information System (INIS)

    Aristolochic acid (AA), present in Aristolochia species, is the major causative agent in the development of severe renal failure and urothelial cancers in patients with AA nephropathy. It may also be a cause of Balkan endemic nephropathy. Epithelial cells of the proximal tubule are the primary cellular target of AA. To study whether organic anion transporters (OATs) expressed in proximal tubule cells are involved in uptake of AA, we used human epithelial kidney (HEK293) cells stably expressing human (h) OAT1, OAT3 or OAT4. AA potently inhibited the uptake of characteristic substrates, p-aminohippurate for hOAT1 and estrone sulfate for hOAT3 and hOAT4. Aristolochic acid I (AAI), the more cytotoxic and genotoxic AA congener, exhibited high affinity for hOAT1 (Ki = 0.6 μM) as well as hOAT3 (Ki = 0.5 μM), and lower affinity for hOAT4 (Ki = 20.6 μM). Subsequently, AAI-DNA adduct formation (investigated by 32P-postlabelling) was used as a measure of AAI uptake. Significantly higher levels of adducts occurred in hOAT-expressing cells than in control cells: this effect was abolished in the presence of the OAT inhibitor probenecid. In Xenopus laevis oocytes hOAT-mediated efflux of p-aminohippurate was trans-stimulated by extracellular AA, providing further molecular evidence for AA translocation by hOATs. Our study indicates that OATs can mediate the uptake of AA into proximal tubule cells and thereby participate in kidney cell damage by this toxin.

  16. ON THE ORIGIN OF THE BALKAN PENINSULA SALMONIDS

    Directory of Open Access Journals (Sweden)

    Simo Georgiev

    2003-12-01

    Full Text Available This paper puts forward the knowledge of the immigration itineraries of the ancestors of five extant salmonid species on Balkan Peninsula which are the following: Acantholingua ohridana (Steindachner, 1892, Hucho hucho (Linnaeus, 1758, Salmo trutta Linnaeus, 1758, Salmothymus obtusirostris Heckel, 1851 and Thymallus thymallus (Linnaeus, 1758. The thesis for the migration itineraries is based on the anatomical, molecular and zoogeographical facts recently published. These latest facts complement or reject the previous thesis that considered the origin of separate species, which in this paper are analyzed together. A new position on the origin of some S. trutta populations inhabiting the Mediterranean Sea watershed is proposed. The new thesis is that they did not inhabit it from the west, through the Atlantic Ocean and Gibraltar, but from the North, through the branches of the former Sarmatian Sea, using the continental way. A. ohridana and S. obtusirostris, the only endemic Balkanean salmonids, have developed here from the mutual ancestor with the extant Siberian Brachymystax lenok (Pallas, 1773. This ancestor came first, together with the S. trutta lineage known as »marmorata«. Using the same migration way, the T. thymallus population of Soča River, the North.West boundary of Balkan Peninsula remained restricted at that corner of Adriatic Sea watershed. In the Black Sea watershed (the Danube River flow extension on Balkan Peninsula the distribution of T. thymallus coincides with the distribution of H. hucho. The thesis which has been proposed for this, largest contemporary Balkan Peninsula salmonid fish was that it came here last, after the connections between the Mediterranean Sea basin and once existent Sarmatian Sea disappeared. This occurred after the end of the last glaciations. This has been concluded on the basis of the exclusion of the areas of the »marmorata« lineage of S. trutta (Mediterranean Sea watershed and H. hucho (Black Sea

    Full Text Available The article discusses the three dominant, Europe-wide, constructions of Europe in the nineteenth and twentieth centuries, and claims that all three found their proponents in the Balkans in the same period, while no specifically Balkan construction of Europe can be identified. The discourses which constructed Europe were transnational, and every search for national discourses must recognize that they are always fractured and contradictory, composed of various elements originating in Europe-wide discourses on Europe. Throughout this period the dominant discourse of Europe was shaped by the discourse of modernity and modernization, not only in Europe but in other parts of the globe as well. Several commentators have already noted that the current challenge of the interwar construction of Europe - peace, prosperity, democracy and human rights - mirrors the crisis of Yugoslavia, and many examples point to the unsustainability of this construction at the beginning of the twenty-first century. Gadamer’s hermeneutics offers a valuable lesson in humility and defines the oft-repeated phrase of “belonging together” as listening to the other in the belief that the other may be right, which should be taken as a starting point for any future construction of Europe.

    2016-08-01

    In the 'older' literature, a definitive renal pathology was described in patients with long-standing hypokalaemia and depletion of the body's potassium reserves. The topic is relevant because possibly a quite cheaply reversible element in the course of chronic kidney disease progression could be addressed. Earlier, pathologists drew attention to vacuolar changes in renal tubular epithelium accompanied by inflammatory interstitial changes in patients with potassium losses. The diagnostic term 'kaliopenic nephropathy' was coined to describe such patients. Kaliopenic nephropathy now receives less emphasis than in earlier times. However, with eating disorders, laxative abuse and other potential causes, we suggest that the syndrome should be resurrected. PMID:27478593

Etymologies of Balkan words and German words must be distinguished. Loanwords in Balkan languages are confined to words which are traceable back to Germanic languages, e. g. Gothic, Old and Middle High German and contemporary German. Not only the word store but also onomastics were occasionally influenced by German languages, but it is not possible to speak of a German substrat or adstrat in the way we can speak of a Thracian or Illyrian substrat, or Greek or Romance adstrat. Dziedzictwo germańskie w językach bałkańskichW słownictwie każdego z języków bałkańskich występują pewne germańskie elementy, poczynając od starobułgarskich tekstów biblijnych, a kończąc na współczesnych językach bałkańskich, jakimi są: bułgarski, macedoński, serbski, albański, rumuński i nowogrecki. W badaniach nad etymologią należy wyraźnie rozgraniczać dwa nurty rozwojowe: germański i bałkański.

    2012-08-01

    Full Text Available A simple listing of lexical evidential markers in Bulgarian, Macedonian and Albanian uncovers unusual problems, because a significant part of the markers are common, both due to genetic relations between the languages (e.g. Bulg. and Maced. spored and to areal factors (e.g. Turk. word güya / gûya was loaned into Bulg. dialectal gyoa, Maced. ǵoa and Alb. gjoja; this marker also exists in Serb.. But these common markers with the same etymology do not necessarily have similar meanings, which is both a theoretical problem for the description of the language data and a practical issue for translation between the languages. As Bulgarian, Macedonian and Albanian have grammatical evidential systems as well, there is a question how the lexical evidential markers interact with evidential forms. Here the distinction between analytic and holistic reading can be quite helpful, as it clarifies the role of each of the components in constructions. In the article it is analysed on the basis of translations between the Balkan languages. The definition of evidentiality I employ in this article is the one stated by A. Aikhenvald: “evidentiality is a linguistic category whose primary meaning is [the] source of information. […] [T]his covers the way in which the information was acquired, without necessarily relating to the degree of [the] speaker’s certainty concerning the statement or whether it is true or not” [Aikhenvald 2004: 3]. It is well known that there is a certain variety of domains for expressing evidentiality; first and foremost there is a distinction between lexical and grammatical markers.1 In the following article I will concentrate on the common lexical evidential markers in Albanian, Bulgarian, and Macedonian, with a short introduction to grammatical evidentiality in these languages._______________________1 As for the grammatical evidential markers in the Balkan languages, there is a tradition of their analysis dating back to the second

    2007-01-01

    Full Text Available The initial phase of the First World War in the Balkans 1914-1915 was a natural continuation of the conflicts opened during the Balkan Wars, but national fervor now encompassed all of the Balkans, from Rijeka and Ljubljana to Athens, Sofia and Bucharest, because the role of the Dual Monarchy had changed from that of an arbiter to that of a participant in the conflict. With the demise of the Ottoman Empire, the further survival of the Habsburg Monarchy was challenged by the Serbian government's Yugoslav project, creating conditions for implementing the nationality principle in all of the Balkans. It seemed that, in support of the alliances that were being created in the Balkans and in Europe as a whole, the time had come for the final fulfillment of the national aspirations of the Balkan peoples. The outcome of this third Balkan war no longer depended solely on the balance of power inside the Balkans, but also on the overall course of the war. After the initial victories in 1914, Serbia suffered a defeat in 1915 and her armies were forced to retreat southward to Albania and Greece, but her Yugoslav project was the foundation of her future policies and the basis for materializing the concept of a common South-Slavic state.

  16. Aristotle vs. Plato: The Balkans' Paradoxical Enlightenment

    Directory of Open Access Journals (Sweden)

    D. Michalopoulos

    2007-09-01

    Full Text Available As it occurred in West, Aristotle’s thought was in Byzantium the main organon of philosophical meditation within the frame of the Christian Faith. Nonetheless, from the ninth century on it was a revival of Platonism that took place – of Neo-Platonism at the beginning and of Platonism itself at the end. The Church, initially indifferent, became suspicious only when, at the turning of the fourteenth to the fifteenth century, the Platonism seemed to engender somewhat a latent paganism; but the Patriarchate was not then able to fight that tendency. So only after the 1453 capture of Constantinople by the Ottomans, Gennadius Scholarius managed to root out from the Greek lands Platonism and its crypto-pagan extension. Be that as it may; the main paradox of the Balkan history is that in the early seventeenth century some leading Greek scholars endorsed the materialist interpretation of Aristotle’s thought – as it was taught in the University of Padua by Cesare Cremonini; and as a corollary this materialistic philosophical system began being taught in both Constantinople and Athens. It was that very way that the Enlightenment took birth in the Balkans – and somehow became a State ideology - long before its prevalence in France. And of course all this had as a result a turn toward Physics and Chemistry with far-reaching consequences

    Full Text Available Balkan region, located in the south eastern part of the European Continent, is composed Albania, Bosnia and Herzegovina, Bulgaria, Montenegro, Kosovo, Macedonia, Greece with a portion of the Croatia, Romania, Serbia, Slovenia and Turkey. Southeast Europe are composed of Slovenia, Croatia, Bosnia and Herzegovina, Serbia, Montenegro, Kosovo, Macedonia and Albania which known as the Western Balkans countries. That international investments are assessed on a regional and global scale in the Balkans, these investments gained importance after the 1990s with political, social and geographical variation. In the 2000s, after legal and administrative framework oriented reforms of investments which are continuations of global integration efforts, development of the investment opportunities in Balkans have been considered positively. While the investment incentive structures and rates differ on the basis of the countries, they are of capital importance for investors. After the 2008 global economic crisis which has happened because of the economic shrinkage on global scale, despite the worries for political and economic unsteadiness in specific countries, development of investments in Balkans has not been affected in a negative way. In this study development of investment in Balkans is analysed with negative and positive factors, investment opportunities and incentives are examined on the basis of countries. The Balkans gain acceleration positively thanks to the reforms of investment opportunities on the national scope. As to the need of investment development oriented local and international coordinated programme and approach is an important issue that should be analysed.

Considering the fact that the knowledge regarding mancala is still quite modest, in this paper, we have also examined the different aspects of this game: the question of its origin, which is linked to the beginning of the Neolithic Age on the territories of Africa and the Near East; the link with the methods of geomantic divination; the anthropological knowledge regarding playing mancala in traditional communities; the distribution and the directions of its diffusion, as well as the archaeological finds in the area Mediterranean.

  20. The vegetational history of the Balkans

    Science.gov (United States)

    Willis, K. J.

    The vegetational history of the Balkans from the last glacial through to present features a dynamic system not subject to immigration of additional taxa. Many temperate taxa appear to have survived in this region during the last glacial in low but persistent populations. Evidence suggests that a greater diversity of taxa existed in the mid to high altitude sites probably where the climate was more humid. At the lateglacial/Holocene transition many tree taxa expanded simultaneously with no evidence of the time-transgressive appearance of taxa which is taken to be indicative of differential immigration in northern Europe. Expansion of temperate woodland was at least 1000 years earlier than in northern Europe suggesting that this was the minimum time for migration of temperate trees into northern Europe. Changes in the composition of the early Holocene woodland included expansion of Pistacia between 9000 and 8000 14C BP, a change in the forest dominants between 8000 and 7000 14C BP, and the appearance and increase of Carpinus orient./Ostrya, Abies. Carpinus betulus and Fagus between 7500 and 5000 14C BP. Since all types were present in the region from the lateglacial, it is suggested that factors other than migration are responsible for their population increase. These factors are considered and include climate, soil development, establishment time and anthropogenic disturbance. Development of the present day landscape started at approximately 4500 14C BP with the onset of anthropogenic disturbance. Clearance resulted in the increase of open ground herbaceous types with grasses, Cerealia-type and Plantago lanceolata. New trees also to become established included Juglans, Olea, Castanea and Platanus. At least two of these types ( Juglans and Castanea) were present in the Balkans during the lateglacial suggesting that although some types were imported by the Greeks/Romans others may have expanded in situ as a result of a favourable niche being created by anthropogenic

    Full Text Available Introduction. The analysis of frequency of kidney diseases, causes of terminal renal failure in patients subjected to repeated dialysis in major dialysis centers in the region of Kosovo and Metohija as well as mortality rate in these patients showed a stable number of patients with kidney diseases, evidencing that the populations of Vitina and Gnjilane were the most commonly affected. These towns are designated as regions with the highest incidence of Balkan endemic nephropathy. The present analysis was aimed at: 1. establishing the incidence rate of hypertension and renal function impairment by using clinical and laboratory analyses in individuals from Vitina and neighboring villages, and 2. investigating the correlation between creatinine clearance, age and arterial blood pressure in the studied group. Material and methods. The analysis included 510 individuals (excluding diabetics over the one-month period during 2004 (201 males with their age ranging from 18 to 90 years. Blood pressure measurements were performed in all the individuals, while renal function was determined by glomerular filtration rate (GFR, as calculated according to Cockcroft-Gault formula. Results. Creatinine clearance was lower than 100 ml/min in 237 (46.5% individuals, out of whom 62 (12% had GFR below 60 ml/min. Among the remaining 273 (53.5% individuals with GFR above 100 ml/min, 68 individuals had GFR above 140 ml/min. The distribution of patients depending on their systolic blood pressure values revealed that systolic blood pressure was lower in 44 subjects and higher in 302 subjects (59%. The correlation test revealed significant association between the studied parameters. The positive correlation between patients' age and kidney function means the higher the age of subjects the lower creatinine clearance value (r=-0.622, p<0.001. The negative correlation of the systolic blood pressure value and kidney function was found, meaning that higher the systolic blood

    Full Text Available Diabetic nephropathy is a clinical syndrome characterized by persistent albuminuria, a relentless decline in GFR, raised arterial blood pressure, and increased relative mortality for cardiovascular diseases. The pathogenesis of diabetic nephropathy is multifactorial, with contributions from metabolic abnormalities, hemodynamic alteration, and various growth and genetic factors. The identification of the main genes would allow the detection of those individuals at high risk for diabetic nephropathy and better understanding of its pathophysiologyas well.The present review discusses the main information available in literature regarding some genetic variants (involved in the renin-angiotensin system, glucose and lipid metabolism and some cytoskeleton proteins that reaffirms the importance of genetic factors in diabetic nephropathy.

    The karst areas in the Dinaric region of the Western Balkan Peninsula are a hotspot of freshwater biodiversity. Many investigators have examined diversification of the subterranean freshwater fauna in these karst systems. However, diversification of surface-water fauna remains largely unexplored. We assessed local and regional diversification of surface-water species in karst systems and asked whether patterns of population differentiation could be explained by dispersal–diversification processes or allopatric diversification following karst-related microscale vicariance. We analyzed mitochondrial cytochrome c oxidase subunit I (mtCOI) sequence data of 4 caddisfly species (genus Drusus) in a phylogeographic framework to assess local and regional population genetic structure and Pliocene/Pleistocene history. We used BEAST software to assess the timing of intraspecific diversification of the target species. We compared climate envelopes of the study species and projected climatically suitable areas during the last glacial maximum (LGM) to assess differences in the species climatic niches and infer potential LGM refugia. The haplotype distribution of the 4 species (324 individuals from 32 populations) was characterized by strong genetic differentiation with few haplotypes shared among populations (16%) and deep divergence among populations of the 3 endemic species, even at local scales. Divergence among local populations of endemics often exceeded divergence among regional and continental clades of the widespread D. discolor. Major divergences among regional populations dated to 2.0 to 0.5 Mya. Species distribution model projections and genetic structure suggest that the endemic species persisted in situ and diversified locally throughout multiple Pleistocene climate cycles. The pattern for D. discolor was different and consistent with multiple invasions into the region. Patterns of population genetic structure and diversification were similar for the 3 regional

  10. Angiopoietins and diabetic nephropathy.

    Science.gov (United States)

    Gnudi, Luigi

    2016-08-01

    Diabetic nephropathy is the main cause of end-stage renal failure in the Western world. In diabetes, metabolic and haemodynamic perturbations disrupt the integrity of the glomerular filtration barrier, leading to ultrastructural alterations of the glomeruli, including podocyte foot process fusion and detachment, glomerular basement membrane thickening, reduced endothelial cell glycocalyx, and mesangial extracellular matrix accumulation and glomerulosclerosis, ultimately leading to albuminuria and end-stage renal disease. Many vascular growth factors, such as angiopoietins, are implicated in glomerular biology. In normal physiology angiopoietins regulate the function of the glomerular filtration barrier. When they are dysregulated, however, as they are in diabetes, they drive the cellular mechanisms that mediate diabetic glomerular pathology. Modulation of angiopoietins expression and signalling has been proposed as a tool to correct the cellular mechanisms involved in the pathophysiology of diabetic microvascular disease, such as retinopathy in humans. Future work might evaluate whether this novel therapeutic approach should be extended to diabetic kidney disease. PMID:27207083

    Full Text Available The current global economic crisis has affected the development of banking system in Western Balkan Countries, including Italy and Greece. These effects are expressed with the contraction of lending, fallen of foreign direct investments, fallen of the volume of remittances and fallen of international trade. The banking system continually faces new challenges in a dynamically changing financial system, and this makes difficult theimplementation of bank regulation and supervision.All the countries have improved their banking regulation in order to avoid the contagion effect among banks and banking system in general, effects that get increased especially when banks are engaged in international banking. The standardization of regulatory requirements provides potential solution to the problems of regulating international banking. So, there is a moving through agreements like Basel Accords.For all these countries will be a comparison of regulatory capital to risk-weighted assets ratio and of capital to assets ratio in order to find out how well is capitalized their bankingsystem. The sources of data are the reports of International Monetary Fund for a time series of 2008-2013. In the end there are some conclusions for the main problems that theimplementation of supervision and bank regulation faces.Keywords: Basel Accords, Capital Ratio, Banking Regulation

Their education, cultural patterns, relations and models inspired by Britain are looked at, showing that they acted as intermediaries between British culture and their own and played a part in the best and worst moments in the history of mutual relations, such as the Serbian-Ottoman crisis of 1862, the Anglo-Hellenic crisis following the Dilessi murders, Bulgarian atrocities and the Eastern Crisis, unification of Bulgaria and the Serbo-Bulgarian War of 1885, the Balkan Wars 1912-13, the National Schism in Greece. Their biographies are therefore essential for understanding Anglo-Balkan relations in the period under study. The roles of two British Balkanophiles (a Bulgarophile, James David Bourchier, and a Hellenophile, Ronald Burrows are looked at as well. In conclusion, a comparison of the Balkan Anglophiles is offered, and their Britain-inspired cultural and institutional legacy to their countries is shown in the form of a table.

    Widespread contamination by depleted uranium was not detected in the Balkan area. - The contribution of the conflict of 1999 to the environmental levels of uranium in the Balkan area was evaluated by means of lichens used as biomonitors. The average U concentration found in lichens in the present study was in line with the values reported for lichens from other countries and well below the levels found in lichens collected in areas with natural or anthropogenic sources of U. Measurement of isotopic ratios {sup 235}U/{sup 238}U allowed to exclude the presence of depleted uranium. According to these results, we could not detect widespread environmental contamination by depleted uranium in the Balkan area.

In this work we study the causes for the cultural and social integration of hunter-gatherer communities in the Late Glacial and Early Holocene, social networks and contacts in the Iron Gates Mesolithic, and also factors having an impact on the spread of the Neolithic in the Balkans. It has been perceived that the evolution of culture in the Balkans was simultaneously influenced by internal and external factors, and this contributed to the very rapid acceptance of Neolithic values and the Neo- lithic way of life in the period from 6500 to 6200 calBC.

First, it comes from interviving linguistics and humanities, that inspired new understanding of the relationship between structure and power. While emerging from cultural studies and therefore from synthesis of history and literary criticism, studies on the Balkan, point out a role of mental images, stereotypes, discourses and therefore, political power of its image. Following the concepts of Michel Foucault, Jacques Lacan, Jacques Derrida and to lesser extent Julia Kristeva, the Balkans is set within the post-structural paradigm.

    The Balkans is a biogeographically highly diverse region and a worldwide hotspot of endemic freshwater diversity. A substantial part of this diversity is attributed to well recognized and potential ancient lakes in its southwestern part. However, despite considerable research efforts, faunal relationships among those lakes are not well understood. Therefore, genetic information from native representatives of the mussel genus Dreissena is here used to test the biogeographical zonation of the southwestern Balkans, to relate demographic changes to environmental changes, to assess the degree of eco-insularity, to reconstruct their evolutionary history, and to explore the potential of native taxa for becoming invasive. Phylogeographical and population genetic analyses indicate that most studied populations belong to two native species: D. presbensis (including the distinct genetic subgroup from Lake Ohrid, "D. stankovici") and D. blanci. In addition, the first confirmed record of invasive D. polymorpha in the southwestern Balkan is presented. The distribution of native Dreissena spp. generally coincides with the biogeographical zonations previously suggested based on fish data. However, there is disagreement on the assignment of the ancient lakes in the area to respective biogeographical regions. The data for Lake Ohrid are not conclusive. A closer biogeographical connection to lakes of the Vardar region and possibly the northern Ionian region is, however, suggested for Lake Prespa. The reconstruction of the evolutionary history of Dreissena spp. suggests that populations underwent demographic and spatial expansions in the recent past. Expansions started around 320 000-300 000 years ago in "D. stankovici", 160 000-140 000 years ago in D. blanci, and 110 000-70 000 years ago in D. presbensis. These time frames are discussed within the context of available paleogeological data for lakes Ohrid and Prespa. It is suggested that regional environmental changes may have had

An early clinical sign of this complication is an increase of urinary albumin excretion, called microalbuminuria, which is not only a predictor of the progression of nephropathy, but also an independent risk factor for cardiovascular disease. Although microalbuminuria is clinically important to assess the prognosis of diabetic patients, it may be insufficient as an early and specific biomarker of diabetic nephropathy because of a large day-to-day variation and lack of a good correlation of microalbuminuria with renal dysfunction and pathohistological changes. Thus, more sensitive and specific biomarkers are needed to improve the diagnostic capability of identifying patients at high risk. The factors involved in renal tubulo-interstitial damage, the production and degradation of extracellular matrix, microinflammation, etc., are investigated as candidate molecules. Despite numerous efforts so far, the assessment of these biomarkers is still a subject of ongoing investigations. Recently, a variety of omics and quantitative techniques in systems biology are rapidly emerging in the field of biomarker discovery, including proteomics, transcriptomics, and metabolomics, and they have been applied to search for novel putative biomarkers of diabetic nephropathy. Novel biomarkers or their combination with microalbuminuria provide a better diagnostic accuracy than microalbuminuria alone, and may be useful for establishing personal medicine. Furthermore, the identification of novel biomarkers may provide insight into the mechanisms underlying diabetic nephropathy.

  3. „Pseudo-yat“ in Dalmato-Romance and Balkan Latin (On Balkan Latin VIII

    Full Text Available Article discusses the origins and the development of the so-called pseudo-yat in Dalmatian Romance and Balkan Latin. (E.g. SCr. mrčela-murtila-murtela from Lat. *MYRTICELLA or tovijerna-tovirna-toverna from TABERNA. Pseudo-yat is derived from -ECC-, in short syllables, and in long syllables from -ERR-, -ERC-. This suggestion is tried on 58 Dalmatian loans in Serbo-Croatian. The fact that pseudo-yat is found only in a part of these is of particular significance for the stratification of Dalmatian loans in Serbo-Croatian since loans with pseudo-yat are ostensibly older than the ones without it.

    Diabetic nephropathy patients traditionally show significant macroalbuminuria prior to the development of renal impairment. However, this clinical paradigm has recently been questioned. Epidemiological surveys confirm that chronic kidney disease (CKD) diagnosed by a low glomerular filtration rate (GFR) is more common in diabetic patients than in the non-diabetic population but a low number of patients had levels of proteinuria above that which traditionally defines overt diabetic nephropathy (>500 mg/g). The large number of patients with low levels of proteinuria suggests that the traditional clinical paradigm of overt diabetic nephropathy is changing since it does not seem to be the underlying renal lesion in most of diabetic subjects with CKD.

    Full Text Available The Balkans region (also known as the „Powder keg of Europe” has always been an European question, a Western question, as underlined by Arnold Toynbee, in 1922. At present, European Union is confronted with the fifth enlargement, also known as the “post-conflict” enlargement – the integration of Balkan states. Bulgaria joined European Union in 2007. Croatia signed the Accession Treaty in 2011 and is expected to become an EU member in 2013. The other countries encounter in different stages of European integration. However, this process presents several challenges and dilemmas, either for European Union, or for the Balkan enclave. The main challenge in the case of this enlargement is to reconcile the nation-state building and the European integration. From the economic point of view, the Balkans region is underdeveloped. Several factors determined this stance of the region: the poor endowment in terms of natural resources, the political situation over the centuries (the military conflicts – impeding the economic development, the cultural factors. At present, the region is confronted with the consequences of the worst economic and financial crisis o global economy since the end of World War II.

  7. Record Balkan floods of 2014 linked to planetary wave resonance.

    In May 2014, the Balkans were hit by a Vb-type cyclone that brought disastrous flooding and severe damage to Bosnia and Herzegovina, Serbia, and Croatia. Vb cyclones migrate from the Mediterranean, where they absorb warm and moist air, to the north, often causing flooding in central/eastern Europe. Extreme rainfall events are increasing on a global scale, and both thermodynamic and dynamical mechanisms play a role. Where thermodynamic aspects are generally well understood, there is large uncertainty associated with current and future changes in dynamics. We study the climatic and meteorological factors that influenced the catastrophic flooding in the Balkans, where we focus on large-scale circulation. We show that the Vb cyclone was unusually stationary, bringing extreme rainfall for several consecutive days, and that this situation was likely linked to a quasi-stationary circumglobal Rossby wave train. We provide evidence that this quasi-stationary wave was amplified by wave resonance. Statistical analysis of daily spring rainfall over the Balkan region reveals significant upward trends over 1950-2014, especially in the high quantiles relevant for flooding events. These changes cannot be explained by simple thermodynamic arguments, and we thus argue that dynamical processes likely played a role in increasing flood risks over the Balkans. PMID:27152340

    Full Text Available Sphingolipids are components of the lipid rafts in plasma membranes, which are important for proper function of podocytes, a key element of the glomerular filtration barrier. Research revealed an essential role of sphingolipids and sphingolipid metabolites in glomerular disorders of genetic and non-genetic origin. The discovery that glucocerebrosides accumulate in Gaucher disease in glomerular cells and are associated with clinical proteinuria initiated intensive research into the function of other sphingolipids in glomerular disorders. The accumulation of sphingolipids in other genetic diseases including Tay-Sachs, Sandhoff, Fabry, hereditary inclusion body myopathy 2, Niemann-Pick and nephrotic syndrome of the Finnish type and its implications with respect to glomerular pathology will be discussed. Similarily, sphingolipid accumulation occurs in glomerular diseases of non-genetic origin including diabetic kidney disease (DKD, HIV-associated nephropathy, focal segmental glomerulosclerosis (FSGS and lupus nephritis. Sphingomyelin metabolites, such as ceramide, sphingosine and sphingosine-1-phosphate have also gained tremendous interest. We recently described that sphingomyelin phosphodiesterase acid-like 3b (SMPDL3b is expressed in podocytes where it modulates acid sphingomyelinase (ASMase activity and acts as a master modulator of danger signaling. Decreased SMPDL3b expression in post-reperfusion kidney biopsies from transplant recipients with idiopathic FSGS correlates with the recurrence of proteinuria in patients and in experimental models of xenotransplantation. Increased SMPDL3b expression is associated with DKD. The consequences of differential SMPDL3b expression in podocytes in these diseases with respect to their pathogenesis will be discussed. Finally, the role of sphingolipids in the formation of lipid rafts in podocytes and their contribution to the maintenance of a functional slit diaphragm in the glomerulus will be discussed.

  10. Mafia links between the Balkans and Scandinavia. State of affairs

    Full Text Available The last twenty years has seen an increasing presence of Balkan organized crime groups in security reports and newspapers' headlines. This does not mean that mafia groups did not exist during Socialist Yugoslavia – even if its collapse and the following war made criminals and smugglers useful for politicians and leaders to maintain their power; it rather means that Balkan organized crime came outside its traditional areas of action in Serbia, Montenegro and Albania: less territorial and nationalist than it was before, it is now gaining prominence in an international scenario, making agreements with Italian and South American mafias – the so-called Holy Alliance – to manage drug routes towards Western Europe. One of the most interesting factors concerning Balkan mafia groups today is their presence in countries which traditionally do not have a history of organized crime, such as the Scandinavian states. One of the reasons lies in the wide percentage of immigrants moving from Balkan countries to Sweden or Norway. Since the wars of the 1990s in the former Yugoslavia, war-crimes fugitives were able to become common criminals in these countries, such as the infamous Želiko Raznjatović (“Arkan”. However, year by year, these gangs grew larger, taking advantage of the “expertise” and the resources gained during the war. In particular, the most spectacular case – the Våstberga helicopter robbery in 2009 – showed how these groups operate with military-style precision, utilize a wide number of participants, and have at their disposal laerge amounts of weapons and money. This paper will draw on the importance of Scandinavian – Balkan mafia relations in relation to three main criminal areas: drug and weapon smuggling and human trafficking, in order to underline the role of diasporas in enforcing organized crime groups and the extent to which these mafias could be a threat for the stability in both Eastern and Western Europe.

    Full Text Available The tiger beetle fauna of the Balkan Peninsula is one of the richest in Europe and includes 19 species or 41% of the European tiger beetle fauna. Assembled by their biogeographical origins, the Balkan tiger beetle species fall into 14 different groups that include, Mediterranean, Middle Oriental, Central Asiatic, Euro-Siberian, South and East European, Pannonian-Sarmatian, West Palaearctic, Turano-European and Afrotropico Indo-Mediterranean species. The Mediterranean Sclerophyl and the Pontian Steppe are the Balkan biogeographical provinces with the highest species richness, while the Balkan Highlands has the lowest Cicindelidae diversity. Most species are restricted to single habitat types in lowland areas of the Balkan Peninsula and only Calomera aulica aulica and Calomera littoralis nemoralis occur in respectively 3 and 4 different types of habitat. About 60% of all Balkan Cicindelidae species are found in habitats potentially endangered by human activity.

    Full Text Available The article presents an observation on the various traditional forms of cross-border seasonal labour mobility on the Balkans, both as agricultural works away from the home place, and as large-scale temporary craftsmen’s migrations of builders, bakers, dairy workers, confectioners and so on. In countries like Albania, Bulgaria, Greece, Macedonia and Serbia, traditional cultural models of trans-border labour mobility that encompasses the majority of the male population of entire regions have existed for centuries. These migrant groups created the specific subculture of gurbet, which the men carried with them in the big city, at the same time altering the entire model of traditional culture in their home regions. The annual journeys of men from the various mountain parts of the Balkans “at work” and “for gain” (pečalba in the course of the years developed specific features of the feast-ritual system and folklore in the villages of these regions. At the same time, the traditional Balkan gurbet is an important condition for mutual penetration between various cultures and peoples and for creating new cultural patterns and various multidimentional identities.

    Kyriakos D. Kentrotis

    2010-09-01

    Full Text Available The European Union continues to constitute an incomplete economic-political entity at intergovernmental and supranational level. The EU is seeking to establish appropriate functional superstructures extending beyond the narrow confines of trade, the economy and free market rules to accommodate its integral progress as a new force for prosperity, democracy and peace in the world. On the map of the Balkans, the local political actors continue to define their choices in line with their historic experience and stereotypes, especially as regards their neighbours and the Great Powers of the moment. The Balkan countries, which in any case are still seeking to consolidate their conventional state structures, need much more time to find their place within this unfinished supranational European structure. In both cases the actors involved, whether in the EU or in the Balkans, are grappling with the challenges of global politics from their different starting-points, but it is not easy to overcome the boundaries of their national sovereignty.

    Full Text Available The countries of the Balkan Peninsula have become the region with frequent outbreaks of the emerging and re-emerging diseases during the last decade of the 20th and the first decade of the 21st century. The majority of outbreaks were wildlife zoonotic, and vector-borne diseases, such as brucellosis, leptospirosis, listeriosis, tularemia, Q-fever, Lyme disease, anthrax, rabies, viralhemorrhagic fevers, sandfly fever, tick-borne encephalitis and leishmainiasis. Epidemiological factors determined by ecology ofcausative agents are often the most useful diagnostic clues. The recognition of evolving problems of emerging and re-emergingdiseases emphasizes the need for the development of better laboratory diagnostic methods for the surveillance and tracking ofthe diseases, and for continued research of factors contributing to the transmission of the organisms. The continuous occurrence of previously unidentified infections requires prospective nationalstrategies for timely recognition of the syndromes, causative agent identification, establishment of criteria and methods for the diagnosis, optimization of the treatment regime, and determinationof successful approaches to prevention and control. Wildlife diseasessurveillance in the most of the Balkan countries has been coordinated by the WHO since 1992. Although new technology and communication have extremely improved in the last decade, there is a need for optimal communication lines among the Balkan countries, better exploitation of communication technologies like the Internet and other media in the field of emerging diseases.

  4. Renal function in diabetic nephropathy.

    2010-05-15

    Diabetic nephropathy is the kidney disease that occurs as a result of diabetes. Cardiovascular and renal complications share common risk factors such as blood pressure, blood lipids, and glycemic control. Thus, chronic kidney disease may predict cardiovascular disease in the general population. The impact of diabetes on renal impairment changes with increasing age. Serum markers of glomerular filtration rate and microalbuminuria identify renal impairment in different segments of the diabetic population, indicating that serum markers as well as microalbuminuria tests should be used in screening for nephropathy in diabetic older people. The American Diabetes Association and the National Institutes of Health recommend Estimated glomerular filtration rate (eGFR) calculated from serum creatinine at least once a year in all people with diabetes for detection of kidney dysfunction. eGFR remains an independent and significant predictor after adjustment for conventional risk factors including age, sex, duration of diabetes, smoking, obesity, blood pressure, and glycemic and lipid control, as well as presence of diabetic retinopathy. Cystatin-C (Cys C) may in future be the preferred marker of diabetic nephropathy due differences in measurements of serum creatinine by various methods. The appropriate reference limit for Cys C in geriatric clinical practice must be defined by further research. Various studies have shown the importance of measurement of albuminuria, eGFR, serum creatinine and hemoglobin level to further enhance the prediction of end stage renal disease. PMID:21537427

    The determinant of the diabetic nephropathy is hyperglycemia, but hypertension and other genetic factors are also involved. Glomerulus is the focus of the injury, where mesangial cell proliferation and extracellular matrix occur because of the increase of the intra- and extracellular glucose concentration and overexpression of GLUT1. Sequentially, there are increases in the flow by the poliol pathway, oxidative stress, increased intracellular production of advanced glycation end products (AGEs), activation of the PKC pathway, increase of the activity of the hexosamine pathway, and activation of TGF-beta1. High glucose concentrations also increase angiotensin II (AII) levels. Therefore, glucose and AII exert similar effects in inducing extracellular matrix formation in the mesangial cells, using similar transductional signal, which increases TGF-beta1 levels. In this review we focus in the effect of glucose and AII in the mesangial cells in causing the events related to the genesis of diabetic nephropathy. The alterations in the signal pathways discussed in this review give support to the observational studies and clinical assays, where metabolic and antihypertensive controls obtained with angiotensin-converting inhibitors have shown important and additive effect in the prevention of the beginning and progression of diabetic nephropathy. New therapeutic strategies directed to the described intracellular events may give future additional benefits. PMID:17934656

    Full Text Available In The Secret of Chimneys (1925 Agatha Christie uses the all too familiar Balkan stereotypes of backwardness and brigandage, but not – as was usually the case at the time – as an Other to illustrate British virtue, but as a mirror to British vice. It is Britain, not the fictional Herzoslovakia, that is a nation of brigands. Herzoslovakia remains relatively unknown, as none of the novel’s scenes take place there, but it is described by disinterested observers as democratic and prosperous. In London, however, the Foreign Office plans to overthrow its government to secure oil rights promised by a royal heir-in-exile to a London-based financial consortium. Keywords: Christie, Balkans, Romania, oil, brigandsAgatha Christie’s The Secret of Chimneys (1925 has been faulted for being on the one hand a frothy mix of Anthony Hope and P. G. Wodehouse (Thompson 143 and on the other a mishmash of popular ethnic, national and regional stereotypes – including those of the Balkans (Todorova 122. It is, however, a far more subtle work than such accounts suggest. Though the influence of Hope and Wodehouse can certainly be seen in the novel’s story of princes in disguise (reminiscent of The Prisoner of Zenda and a country house setting that would have reminded readers of Blandings, its main plot addresses an important theme –and in exploring it Christie takes the Balkans very seriously. Oil has been found in the Republic of Herzoslovakia and the Foreign Office, represented by George Lomax, has secured the pledge of the exiled Prince Michael Obolovitch “to grant certain oil concessions” to a consortium led by Herman Isaacstein if the Obolovitchs are restored to power. In other words: to secure those concessions the British Government has committed itself to the overthrow of Herzoslovakia’s government. The Foreign Office’s interest in the Balkans might not have surprised Christie’s readers. The Anglo-Iranian Oil Company had held a monopoly on

    Diabetic nephropathy accounts for the most serious microvascular complication of diabetes mellitus. It is suggested that the prevalence of diabetic nephropathy will continue to increase in future posing a major challenge to the healthcare system resulting in increased morbidity and mortality. It occurs as a result of interaction between both genetic and environmental factors in individuals with both type 1 and type 2 diabetes. Genetic susceptibility has been proposed as an important factor for the development and progression of diabetic nephropathy, and various research efforts are being executed worldwide to identify the susceptibility gene for diabetic nephropathy. Numerous single nucleotide polymorphisms have been found in various genes giving rise to various gene variants which have been found to play a major role in genetic susceptibility to diabetic nephropathy. The risk of developing diabetic nephropathy is increased several times by inheriting risk alleles at susceptibility loci of various genes like ACE, IL, TNF-α, COL4A1, e NOS, SOD2, APOE, GLUT, etc. The identification of these genetic variants at a biomarker level could thus, allow the detection of those individuals at high risk for diabetic nephropathy which could thus help in the treatment, diagnosis and early prevention of the disease. The present review discusses about the various gene variants found till date to be associated with diabetic nephropathy.

    Full Text Available Joining the European Union has been the main goal of the Western Balkan countries, no matter of their differences in their political and economical development for almost two decades. Therefore, European integration is almost recognized universally as the key strategy for achieving peace, stability and prosperity for the all countries of the Western Balkans. The realization of this project, with no doubts, can be achieved through the European policy makers’ involvement in the Western Balkans, which will lead to a positive and long-lasting effect on the management of ethno-political conflict. Concerning the economical part, in general all Balkan countries are small economies and their possible integration would help them a lot becoming part of a big market, more than a help million consumers. But, this might present also an obstacle for companies of these small Balkan countries because the need to compete with other giant European companies. The integration of the Western Balkan countries with provides new members with many benefits in political as well as in economical part. The liberalization of inter-regional trade will help countries in the region to improve their mutual cooperation economically and politically. The membership in the European Union would motivate all countries in the western Balkans to improve and correct the existing problems and opened issues, and to actively undertake and participate for a better future of the Balkans.

    We report five cases of crescentic IgA nephropathy. All are males, 16-60 years of age. One case each came to medical attention with uremia, nephrotic syndrome, and gross hematuria; two cases presented with microhematuria and proteinuria on routine urinalysis. All had hypertension, azotemia (serum creatinine 1.6-9.4 mg/dl), proteinuria (greater than 6 g/24 hr in four cases), hypoalbuminemia (less than 3 g/dl), and hematuria (gross in two cases). All progressed to end-stage renal failure renal failure ending in dialysis (three cases) or death from unrelated causes (two cases). Prednisone, 60 mg/day for 1 month in two patients (with two 1-g doses of iv methylprednisolone in 1 case) did not improve the serum creatinine level, but one patient subsequently experienced a less rapid fall in renal function. A crescentic glomerulonephritis was present in all biopsies (crescents in 31-80% of glomeruli; mean, 50%). The size and stage of the crescents were variable. Numerous glomeruli had focal or diffuse sclerosis. In all cases, there was a 3 or 4+ deposition of IgA. Low-intensity staining for IgG and IgM was noted in four and three patients, respectively. On electron microscopy, dense granular mesangial deposits were noted in all cases and in four patients capillary subepithelial deposits were also observed. This form of IgA nephropathy is not common, but some studies indicate that it may occur in about 5% of patients with IgA nephropathy.

  14. Clinical management of diabetic nephropathy.

    1999-11-01

    From the viewpoint of nephrologists dealing with diabetic patients with ESRD and the associated complications and devastating prognosis, the need to reduce the incidence, and delay the rate of progression of diabetic nephropathy is obvious. Studies published within the last year have provided support for views that seem intuitively obvious; that improved glycaemic control and reduced blood pressure are associated with delayed onset and delayed progression of diabetic nephropathy. These reports have also demonstrated the difficulty of achieving ideal blood pressure targets and glycaemic control in diabetic patients. Thus, even with available therapy it is likely that improved compliance and achieving targets will have a major impact on disease outcome. There is evidence in several subgroups that ACEi are beneficial over other agents and the favourable side-effect and efficacy profile of these agents makes it reasonable to suggest that they should be used 'first line' in all patients with diabetes unless specifically contra-indicated. However, the failure to readily achieve blood pressure targets and the need for polypharmacy suggest that novel agents are required. We believe that statin therapy will have a major impact on CVD in diabetic patients and is also likely to delay progression; studies assessing the combined affect of anti-hypertensive and statin therapy specifically on the development and progression of diabetic nephropathy will be necessary before evidence-based recommendations can be made. The role for newer agents and targeting high risk groups using genetic markers remains uncertain but we await there development with interest. The future can only get better for patients with DN.

  15. Climate variability and change and related drought on Balkan Peninsula

    International Nuclear Information System (INIS)

    In this paper, results on climate variability including variations of air temperature and precipitation in Bulgaria during the 20th century are presented. There has been an increase of air temperature during the last two decades. The years 1994 and 2000 were the warmest years on record in the country. Annual precipitation in Bulgaria varied considerably from year to year during the 20th century. In some years, very low annual precipitation caused droughts of different intensities. The country has experienced severe drought episodes in the 1940s, 1980s and 1990s. There was a decreasing trend in precipitation during the period April-September from the end of 1970s. Precipitation was below the 1961-1990 average for 14 of the last 20 years of investigation. A winter precipitation deficit was observed during the last decade. Both spring and summer as well as autumn precipitation had a tendency to decrease at the end of the 20th century. The anomalies of annual air temperature and precipitation as well as related drought occurrence on the Balkan Peninsula were also analyzed. For this purpose, different weather sources (such as the CRU climate dataset, ATEAM weather dataset for Europe, etc.) were used. Several climate change scenarios for the Balkan Peninsula were developed and analyzed. These scenarios were based on GCM (global circulation model) weather outputs. Both GCM outputs with coarse spatial resolution (e.g. MAGICC/SCENGEN scenarios: 500 km x 500 km) as well as with high resolution (e.g. HadCM3 scenarios: 10'x 10' (less than 20 km x 20 km)) were used. The GCM climate change scenarios created by the Tyndall Centre (UK) for the Balkan countries were also considered and discussed. (Author)

    Full Text Available Four cores from Balkans lakes Ohrid and Prespa were studied for recognition of tephra layers and cryptotephras, and the results presented along with the review of data from other two already published cores from Lake Ohrid. The six cores provide a previously unrealised tephrostratigraphic framework of the two lakes, and supply the first detailed tephrochronologic profile (composite for the Balkans, which spans from the end of the Middle Pleistocene to the end of the Ancient Age (AD 472. A total of 12 tephra layers and cryptotephras were recognised in the cores. One is of Middle Pleistocene age (131 ky and correlated to the marine tephra layer P-11 from Pantelleria Island. Eight volcanic layers are Upper Pleistocene in age, and encompass the period between ca. 107 ky and ca. 31 ky. This interval contains some of the main regional volcanic markers of the Central Mediterranean area, including X-6, X-5, Y-5 and Y-3 tephra layers. The other layers of this interval have been related to the marine tephra layers C20, Y-6 and C10, while one was for the first time recognised in distal areas and correlated to the Taurano eruption of probable Vesuvian origin. Three cryptotephras were of Holocene age. Two of which have been correlated to Mercato and AD 472 eruptions of Somma-Vesuvius, while the third has been correlated to the FL eruption from Mount Etna. These recognitions provide a link of the Ohrid and Prespa lacustrine successions to other archives of the Central Mediterranean area, like South Adriatic, Ionian, and South Tyrrhenian Seas, lakes of Southern Italy (Lago Grande di Monticchio, Pantano di San Gregorio Magno and Lago di Pergusa and Balkans (Lake Shkodra.

    International Nuclear Information System (INIS)

    Ultrasound(US) findings of hyperechoic renal medulla in gouty nephropathy were compared with clinical features such as serum uric acid level to evaluate its usefulness in determination of the treatment and prognosis. A retrospective review of US of 36 cases of qouty arthritis was classified into four groups according to the medullary echogenicity (O :normal, grade I: renal medulla as isoechoic as renal cortex, grade II; heterogeneous increased echogenicity of renal medulla than that of renal cortex, grade III: the echogenicity of all renal medulla higher than that of renal cortex with renal contour deformity) which were compared with the serum urate level and associated conditions. Nephrocalcinosis and nephrolithiasis were analyzed through the KUB and the RGB. The degree of hyperechoic renal medulla was related to the level of serum uric acid, and in group IV, six cases of obstructive uropathy (nephrocalcinosis and nephrolithiasis) showed deformed renal contour. Associated conditions such as hypertension, alcoholism, diabetes mellitus and drug abuse were distributed in relation to the degree of hyperechoic renal medullas.

    Full Text Available The aim of this paper is to analyze the expansion of the thermal generation in the long-term for the Western Balkan region. This paper concentrates on the estimation of long-term energy data for the (Western Balkan countries. The process was implemented by the use of the PRIMES model in order to perform simulations for the future growth of electricity supply and demand in the region. Two scenarios were applied. The first (Baseline scenario was based on the current energy path of each country and on the absence of any specific energy policy like tax emissions or renewable subsidies. The second (Reference scenario was practically a series of “environmental” sub-scenarios, based on specific energy subsidy policy applied to the electricity generated by renewable sources. Results were given for the period between 2015 and 2050 in 5-year steps and conclusions were made for the whole region. As such, the results can feed up trials of energy planning referring to the future energy condition.

    Full Text Available Actually economic policies in many countries aimed to stimulate their economic growth, particularly after negative impact of the global economic crisis. In this regards, fiscal regulation are an important aspect of those policies, that can promote or obstacle the economic growth in general. In this point of view this paper aims to analyze the system of administration rules in different Western Balkans Countries, (which includes Albania, Bosnia & Herzegovina, Croatia, Kosovo, Macedonia (FYROM, Montenegro and Serbia. Moreover, a special attention is given investigation of the regulation and administrative facilitation aspects of doing business in the above-mentioned countries, whether this system stimulates, or not, the development of private business and economic growth.The paper is divided into three main sections. The first part provides a retrospective of economic growth in the Western Balkan countries and the dependence of this growth on global economic development. The second part proceeds with the investigations of the impact of administrative regulation on economic growth. The third part, based on an econometric model, will analyze the correlation between economic growth and elaborated indicators which present the level of business administrative regulation system. Furthermore, this last section discusses the results and concludes. In this analysis, the paper is based substantially on the data base of "Doing Business 2013" (World Bank.

  4. Overview of poverty and social exclusion in the Western Balkans

    Full Text Available During the last 15 years the entire Western Balkan region has undergone dramatic changes. With the fall of the Berlin wall and the disintegration of the former Yugoslavia, new states were formed and transition started, although in some countries it was quite delayed. Simultaneously, during the nineties, much of the region experienced wars and destruction, waves of refugees, internal displacement of population, devastation of the economy, demolition of institutions and impoverishment of citizens. Absolute poverty, determined through the estimation of household consumption at which families, after paying for essential non-food expenditures just attain minimal nutritional needs, in almost all of the Western Balkans is still relatively high, and is not showing significant tendencies of decreasing. A large concentration of the population and households just above the poverty line additionally demonstrates the challenges faced by the entire region while undergoing the transition process. In some countries extreme poverty, meaning that not even basic food needs can be met, has been registered. On the other hand, relative poverty, defined as the share of those who are excluded from the minimum acceptable way of life in states in which they live, is not particularly high. Due to the relatively high standard of living in the past and high expectations of the population that living standards would increase in a relatively short period of time, the subjective perception of poverty in the entire region is very much present. Groups that stand out as especially vulnerable and excluded are the unemployed, dependents and the less educated. At the level of the household, in some countries households with many children and elderly households are particularly vulnerable. The poorest often live in the rural areas and in the underdeveloped regions. In addition, especially vulnerable groups, who cannot even be completely covered by standard surveys, but are poor and

    Full Text Available Diabetic nephropathy is a clinical syndrome characterized by the following- Persistent albuminuria (>300mg/d or >200μg/min, that is confirmed on at least 2 occasions 3-6 months apart diabetic, progressive decline in the Glomerular Filtration Rate (GFR, elevated arterial blood pressure. The earliest biochemical criteria for the diagnosis of diabetic nephropathy is the presence of micro-albumin in the urine, which if left untreated will eventually lead to End-Stage Renal Disease (ESRD. Micro-albuminuria refers to the excretion of albumin in the urine at a rate that exceeds normal limits. The current study was conducted to establish the prevalence of micro-albuminuria in a sequential sample of diabetic patients attending hospital and OPD Clinic to determine its relationship with known and putative risk factors to identify micro- and normo-albuminuric patients in their sample for subsequent comparison in different age, sex, weight and creatinine clearance of the micro- and normo-albuminuric patients. This cross-sectional analytical study was conducted in one hundred patients at Saraswathi Institute of Medical Sciences, Anwarpur, Hapur, U. P. Patients having diabetes mellitus in different age group ranging from 30 to 70 years were selected. Data was analysed by SPSS software. Micro-albuminuria was observed in 35% in patients with type 2 diabetes mellitus. It was observed that 65% patients were free from any type of albuminuria. Also micro-albuminuria was present in 10% of the patients less than 50 yrs. of age, while 15% of the patients more than 50 yrs. of age were having micro-albuminuria. There was a statistically significant correlation of micro-albuminuria with duration of diabetes. Incidence of micro-albuminuria increases with age as well as increased duration of diabetes mellitus. Our study shows that only 5% patients developed macro-albuminuria. Glycosylated haemoglobin and fasting plasma glucose was significantly raised among all these

The Bosnian pine munika, munjika growing in high and rocky places exposed to the thunder, the relation to S.-Cr. munja < Common Slavic *mъlnja seems probable, and molika may be explained as a re-borrowing from Alb. molikë traceable to the same Slavic prototype *mъlnika.

    2003-01-01

    Full Text Available A review of the fossil horses of the genus Equus from the central Balkans, a mountainous area comprising Serbia and Montenegro, is presented in this paper. The time period covered by the finds is from the late Early to and including the Late Pleistocene, but the record is not complete: the dated finds are Late Pleistocene in age, while Early and Middle Pleistocene are poorly represented. The horses found resemble those from neighbouring countries from the same time period, probably showing the importance of river valleys as migration routes. The Morava River valley runs in a roughly south-to-north direction, connecting, via the Danube and Tisa River valleys the Hungarian Pannonian Plain in the north with northern Greece in the south, via the Vardar River valley in Macedonia. In Pleistocene, large mammals, including horses, probably used this route for dispersal.

    Human immunodeficiency virus (HIV) is one of the most genetically variable human viruses as it is characterized by high rates of mutation, viral replication, and recombination. Phylodynamics is a powerful means of describing the behavior of an infection as a combination of evolutionary and ecological processes. Only a few studies of HIV-1 molecular epidemiology have so far been carried out in the Balkans. In this study, we used Bayesian methods to reconstruct the phylogeography and phylodynamics of HIV-1B in Montenegro and some other Balkan countries on the basis of pol gene sequences retrieved from a public database. The phylogenetic analysis showed that 43% of the isolates grouped in accordance with their geographic area, whereas the majority were interspersed in the tree, thus confirming the multiple introductions of HIV-1B in the Balkans. The Bayesian phylogeographic analysis suggested that HIV-1B entered the Balkans in the early 1970s probably through Greece and other Mediterranean tourist/travel destinations (such as Slovenia). Other Balkan countries, such as Bulgaria and Serbia, may have played an important role in spreading the infection to the entire Eastern Mediterranean area, and possibly to Northeast Europe. This suggests that the Balkans may have played a role as a "gateway" between Western and Eastern Europe. PMID:22364163

    Data on the management of atrial fibrillation (AF) in the Balkan Region are limited. The Serbian AF Association (SAFA) prospectively investigated contemporary 'real-world' AF management in clinical practice in Albania, Bosnia&Herzegovina, Bulgaria, Croatia, Montenegro, Romania and Serbia through a 14-week (December 2014-February 2015) prospective, multicentre survey of consecutive AF patients. We report the results pertinent to stroke prevention strategies. Of 2712 enrolled patients, 2663 (98.2%) with complete data were included in this analysis (mean age 69.1 ± 10.9 years, female 44.6%). Overall, 1960 patients (73.6%) received oral anticoagulants (OAC) and 762 (28.6%) received antiplatelet drugs. Of patients given OAC, 17.2% received non-vitamin K antagonist oral anticoagulants (NOACs). CHA2DS2-VASc score was not significantly associated with OAC use. Of the 'truly low-risk' patients (CHA2DS2-VASc = 0 [males], or 1 [females]) 56.5% received OAC. Time in Therapeutic Range (TTR) was available in only 18.7% of patients (mean TTR: 49.5% ± 22.3%). Age ≥ 80 years, prior myocardial infarction and paroxysmal AF were independent predictors of OAC non-use. Our survey shows a relatively high overall use of OAC in AF patients, but with low quality of vitamin K antagonist therapy and insufficient adherence to AF guidelines. Additional efforts are needed to improve AF-related thromboprophylaxis in clinical practice in the Balkan Region. PMID:26869284

    Full Text Available Introduction Immunoglobulin A nephropathy (IgAN is one of the most common forms of primary glomerulonephritis in many countries. Most clinical features of IgAN point to a renal problem, such as recurrent macroscopic hematuria or asymptomatic microscopic hematuria and proteinuria. Pathologic features of IgAN present with different types and different degrees of glomerular tubulointerstitial and vascular lesions. The aim of this study was detailed analysis of clinical and laboratory findings, as well as findings of immunofluorescence and light microscopy. We also investigated associations between these factors. Material and methods We investigated 60 patients who underwent renal biopsy. The study was partly retrospective and partly prospective. Results The average age of patients was 34.19 years. Male female ratio was 2.33:1. IgAN was most frequently asymptomatic (83.33% as microhematuria and proteinuria, while gross hematuria was found in 16.667%. Renal biopsy material was analyzed by light microscopy revealing changes in all glomerular structures. Immunofluorescence microscopy demonstrated dominant IgA deposits. This study established association of glomerulosclerosis with clinical features of disease. Discussion and conclusions IgAN frequently develops in the 4th decade of life, mostly in males and presents as asymptomatic (83.33%. Patohistological changes include all glomerular structures. There is no specific serological test for IgAN, but pathological changes affect clinical features of the disease, as proteinuria and increase of creatinine concentration.

    Diabetic nephropathy (DN) is a major cause of end-stage renal disease (ESRD), however, specific treatment for DN has not yet been elucidated. Therefore, it is critically important to understand the molecular mechanism underlying DN to develop cause-related therapeutic strategy. To date, various factors such as hemodynamic changes and metabolic pathways have been shown to be involved in the pathogenesis of DN. Excessive glucose influx activates cellular signaling pathways, including the diacylglycerol (DAG)-protein kinase C (PKC) pathway, advanced glycation end-products (AGE), polyol pathway, hexosamine pathway and oxidative stress. These factors interact with one another, thereby facilitating inflammatory processes, leading to the development of glomerulosclerosis under diabetic conditions. In addition to metabolic pathways, Rho-kinase, an effector of small-GTPase binding protein Rho, has been implicated as an important factor in the pathogenesis of DN. A number of studies have demonstrated that Rho-kinase plays key roles in the development of DN by inducing endothelial dysfunction, mesangial excessive extracellular matrix (ECM) production, podocyte abnormality, and tubulointerstitial fibrosis. In this review article, we describe our current understanding of the signaling pathways in DN. PMID:27094540

    Irregular migration on the Western Balkan route has marked an unprecedented number during the last five years. Evidence indicates that both, non-European nationals and Western Balkan citizens have been involved in this complex migratory flow being exposed to various risks of human trafficking. But Western Balkan countries are source, transit and destination countries of human trafficking while their states are not well organized to implement a comprehensive and well-coordinated regional respo...

    Full Text Available Throughout the 550 year Ottoman rule over the Balkan lands, where even today internal dynamics threaten peace and justice, how and through what means the Ottoman Empire achieved consistency, security and peace is a question to which a number of political scientists, sociologists, communication scientists and history researchers have sought an answer. The most interesting point of the question is that the peoples of the Balkans, a living museum comprising a number of different ethnic groups and religious beliefs, have reached the point where the culture of coexistence has been internalised and dynamics have moved from the conflict of identities to cultural integration. The Balkans are a bridge to the East from Europe and indeed to the West from Turkey, incorporating a patchwork political and cultural geography, the geopolitical location and a richness of culture and civilization, being one of the areas attracting the attention of researchers from different disciplines and capturing the imagination of the peoples of the world throughout history. Balkan studies are almost as difficult as climbing the peaks in the areas and meaningful answers cannot be reached by defining the area on a single parameter such as language, culture or traditions, while the phenomenon of the other can also be observed within the culture of coexistence in this intricate and significant location. Different ethnic groups with different cultures, such as the Southern Slavs (Bosniaks, Montenegrans, Serbs, Croats and Slovenes as well as Turks, Albanians, Bulgarians, Balkan Jews, Balkan Romany and Wallachians (Romanians and Greeks. Although these peoples may have different religious beliefs, in the ethnically rich Balkan region, religion, language, political and cultural differences are vital in the formation of a mosaic, making the discourse of coexistence possible and creating common values and loyalties, breaking down differences.

    In this paper we concentrate on the role of infections in IgA nephropathy both from a pathogenetic and clinic point of view. The current hypotheses as regards the role of infections in the pathogenesis of IgA nephropathy are: (a) role of particular pathogens, (b) chronic exposure to mucosal infections, (c) abnormal handling of commensal microbes (gut microbiota). We also focus on particular infections reported in association with classic IgA nephropathy (HIV, malaria, Chlamydia, Lyme disease), as well as on IgA dominant-infection-associated glomerulonephritis. This is a unique form of glomerulonephritis, where IgA deposition is dominant. It is mostly recognized in old, diabetic patients and in association with staphylococcal infection. PMID:26800970

    2004-12-01

    Mitochondrial haplotype diversity in sympatric populations of Ohrid trout, Salmo letnica was investigated by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) analysis of the mtDNA control region and ND1, ND3/4, ND5/6 segments. A 310 bp fragment at the 5' end, and a 340-572 bp fragment at the 3' end of the control region were sequenced from representatives of the populations studied. Based on pairwise comparison of the sequences, five new haplotypes were identified plus one identical with the brown trout Andalusian haplotype from the southern Iberian Peninsula. The combination of both RFLP and sequence data sets yielded a total of 10 composite haplotypes. A high degree of genetic subdivision between S. letnica typicus and S. letnica aestivalis populations was observed. The notion of a sympatric origin for the two morphs is discussed. Length variation of the mtDNA control region due to the presence of an 82 bp unit, tandemly repeated one to four times, in the region between the conserved sequence block-3 (CSB-3) and the gene for phenylalanine tRNA is reported. Further, we demonstrate that a single duplication of the approximately 82 bp repeat unit is a common element of the salmonid mitochondrial control region. The unique genetic structure of Ohrid trout represents a highly valuable genetic resource that deserves appropriate management and conservation. PMID:15548279

    Full Text Available The past decade has witnessed increased globalization of the world economy as result of technological changes, trade liberalization and privatization policies. Balkan countries as developing nations are in the realization process of the globalization changes of the world economy. Being in the process for entry into the EU, many changes are being done to integrate with the global economic trends. The research has shown that after the fall of communism in the 1990s the Balkan Region brought significant political and economic changes. The change in attitude led to a removal of direct blockage for FDI. As a result, continued deregulation and privatization has been widespread. However, history of FDI is relatively short for Balkan Region in comparison with other countries. The economy opened up capital inflows only at the beginning of 1990s, and is still showing low shares in the total of Central and Eastern European flow. Despite Balkans competitive advantage due to its geographical location and its resources, it is still far from other Central European countries in achieving the same level of FDI. This situation came as a result of: political instability, low intraregional trade, the small size of national markets, huge institutional corruption and weak judiciary system. Among the more successful Balkan recipients of FDI has been Bulgaria and Romania, while Greece has been a major source of FDI for the transition economies of the Balkan region. Greek investment is driven in part by the availability of low cost labor in the nearby transition economies. The focus of this article is to analyze and evaluate the current performance of FDI in Balkan Region and how the governments can improve this performance.

    Freshwater fauna of ancient lakes frequently contain endemic taxa thought to have originated during the long existence of these lakes, yet uncertainties remain as to whether they represent distinct genetic lineages with respect to more widespread relatives and to the relative roles of isolation and dispersal in their evolution. Phylogenetic analyses of sequence variation at nuclear and mitochondrial genes were used to examine these issues for the freshwater fish genus Barbus in two European ancient lake systems on the Balkan Peninsula. The nuclear and mitochondrial data yielded concordant phylogeographic patterns though incomplete sorting of nuclear haplotypes between some mitochondrial clades was detected. The distributions of two currently recognized species investigated here do not match the distributions of evolutionary lineages revealed by phylogenetic analyses. The Prespa barbel, Barbus prespensis, is not endemic to the lakes Prespa as previously thought but is instead found to be widespread in the south-eastern Adriatic Sea basin, with a distribution largely corresponding to the basin of the now extinct Lake Maliq historically connected with Lake Prespa. On the other hand, a cryptic phylogenetic subdivision in a widespread species, B. rebeli, was discovered to be more distant from B. rebeli than from other Barbus species and to be endemic to the system of connected lakes Ohrid and Shkodra. The division coincides with the hydrogeographical boundary delimiting distributions of other freshwater fishes, and we suggest that this newly discovered evolutionary lineage represents a distinct species. These findings support the emerging pattern that endemic taxa have evolved not through isolation of individual lakes, but in systems of currently and historically interconnected lakes and their wider basins.

    Full Text Available For half a century, European Union-(EU has pursued ever-deeper integration while taking in new members. It’s marked as an important step in relationship deepening between EU and Western Balkans-(WBs where Albania is part of. In 2003, EU declared that the future of WBs is within EU. Initially it adopted a generous strategy that linked the timetable for accession to the pace of reform in WBs. The declaration contained a conditional promise; EU would consider WBs for membership only if they reached EU standards. The EU was motivated by usual economic considerations connected to enlargement and a desire to increase regional stability. The enlargement process regarding Albania will bring several reforms on different fields. Our country will benefit from a share of multibeneficiary funds for competitiveness, SMEs, energy efficiency and banking sector regulation. This presentation handles out these main issues: EU policy and the enlargement process regarding Albania inspecting the way and progress done up to now by our country, the main features of our national EUcoordination system, concluding in a SWOT Analysis of EU-coordination system in Albania. Eventually, I believe that Albania being part of WBs is at one time an opportunity and a challenge for the future of EU.

    Full Text Available If culture as a term covers a broad range of relations and social behavior, mutually implicated in influential and economic cycles of the global system, then it becomes wordy geoculture. Geoculture system is used as a term by Wallerstein (2004 who had treated it as a concept largely unused and under a theory of geoculture which plays an important role in the present world system. The theses that is presented in this article is that the global trajectory in the Balkan region is increasing from culture and that, it is imperative to establish a strategic culture direction and management, which, in turn, should be formed not only as a principal need, but also as an obligation of social state institutions to find the viable solutions of the global market policy, economy and culture. And in response to the challenging question the culture of integration becomes imperative now facing nationalism. Albania will have to manage perceptions, fears and realities arising from the above mentioned phenomenon, to establish a balance between the “inside” and “outside” views. In this sense main challenge of Albania is the management of cultural globalization to get the most of opportunities despite the risk of losing ground globally

    Full Text Available This paper investigates and compares development of the Entrepreneurship and Small and Medium - sized Enterprises (SMEs sector and different obstacles for development of this sector in the Western Balkan countries (WBCs. Many evidence from the countries of central Europe show that the development of SMEs and entrepreneurship is a key factor for a successful transformation from command to market based economy in WBCs. SMEs create new jobs, products and services, help in restructuring former state enterprises, which is very important for transition countries, and generate government revenues. Also, SMEs stimulate private ownership and entrepreneurial skills and innovations. Aspecial accent in this paper is put on many international reports and datasets relevant to the assessment of business environment in this region. In this paper, the author uses only some such as: The Global Competitiveness Report of World Economic Forum, World Bank’s Doing Business Index, Heritage Foundation's Index of Economic Freedom, European Charter for Small Enterprises and Small Business Act of OECD and European Commission (EC and Indicators of Business, Corruption and Crime in WBCs of the United Nations Office on Drugs and Crime (UNODC. The author has come to the conclusion that, in respect of SMEs, WBCs lag behind the countries in the European Union. This article aims to analyze the system of regulation and administrative facilitation aspects of doing business in the above - mentioned countries and, whether or not this system stimulates, the development of private SMEs and entrepreneurship.

    Full Text Available The paper analyses the development of national identities among Balkan Orthodox Christians from the 1780s to 1914. It points to pre-modern political subsystems in which many Balkan Orthodox peasants lived in the Ottoman Empire at the beginning of the nineteenth century. The Serbian and Greek uprisings/revolutions are analyzed in the context of the intellectual climate of the Enlightenment. Various modes of penetration of the ideas of the Age of Revolution are analyzed as well as the ways in which new concepts influenced proto-national identities of Serbs and Romans/Greeks. The author accepts Hobsbawm’s concept of proto-national identities and identifies their ethno-religious identity as the main element of Balkan Christian Orthodox proto-nations. The role of the Orthodox Church in the formation of ethno-religious proto-national identity and in its development into national identity during the nineteenth century is analyzed in the cases of Serbs, Romans/ Greeks, Vlachs/Romanians and Bulgarians. Three of the four Balkan national movements fully developed their respective national identities through their own ethnic states, and the fourth (Bulgarian developed partially through its ethnic state. All four analyzed identities reached the stage of mass nationalism by the time of the Balkan Wars. By the beginning of the twentieth century, only Macedonian Slavs kept their proto-national ethno-religious identity to a substantial degree. Various analyzed patterns indicate that nascent national identities coexisted with fluid and shifting protonational identities within the same religious background. Occasional supremacy of social over ethnic identities has also been identified. Ethnification of the Orthodox Church, in the period 1831-1872, is viewed as very important for the development of national movements of Balkan Orthodox Christians. A new three-stage model of national identity development among Balkan Orthodox Christians has been proposed. It is

    Full Text Available Effective emotional thoughts like attitudes, stereotyped judgments and preconceptions are dependent on both collective and individual experiences. Experiences like reading an article or watching a movie that is based on a context determined by the curriculum might cause individual or collective discrimination towards different ethnic or cultural groups among students in a country. This study aims to explore the difference between two nations which are the Turkish nation that has many cultural and political bonds with Balkans in the history and the German nation, which is a nation that has little or no bonds with the Balkans. The main aim of the study is to figure out if the stereotypes towards Balkans can change according to the country in which an individual has grown up. MANOVA was used to figure out the difference between two capitals with regard to stereotypes towards Balkans. Findings of the study indicated that negative stereotype scores of students significantly changed according to the country in which students grew up, whereas no significant difference was found for positive stereotype scores. Moreover, it was found that Turkish students have more negative stereotypes towards Balkans than German students

    The needs for spatial data as well as techniques of Earth Observation are changing, and new professional areas are developing very rapidly. In addition, scientific work and its connection with the teaching process have influenced the introduction of new cognitions into the higher education programs in general. Considering these facts, in the period shorter than one decade, the higher education institutions in the Balkan region, which have study programs in the fields of spatial data acquisition, analysis and spatial decisions, have made significant changes of the curricula. In our research, we have analyzed the current higher education programs in the Balkan region having focused on curricula related to the Earth Observation. Due to historical reasons, these curricula have its roots in surveying study programs in the most Balkan countries. The competences of classical surveying higher educational programs have been changing and nowadays include the wider area of spatial data acquisition, geoinformatics. In parallel, we present the current Earth Observation activities in the selected countries from the Balkan region. Based on the results of our research in the framework of the European program Observe, which aims to establish a new Balkan Earth Observation (EO) community of multilevel stakeholders that will make use of state of the art technological developments, products and knowhow from the existing European EO community and industry, we estimate the contribution of advanced higher educational programs to the Earth Observation activities in the selected countries.

The objective of this study was to evaluate prescribing trends in hospitalized patients with diabetic nephropathy. A prospective, observational study was conducted in a tertiary care hospital. The demographic, disease and treatment data of patients with diabetic nephropathy were collected for a period of six months and analysed. Drugs were classified using World Health Organization recommended Anatomic Therapeutic Chemical classification. A total of 755 drugs (7.4 drugs per prescription were prescribed to 102 study patients, who were all hypertensive and in late stages of diabetic nephropathy. Drug classes with largest representation were those acting on gastrointestinal tract plus metabolism (37% and cardiovascular drugs (28%. Calcium channel blockers represented the largest antihypertensive drug class (41%. Almost three-fourths of patients received more than one antihypertensive agent. Approximately 37% of patients did not receive any antidiabetic medication. Of those who did, prescriptions for insulin (91% exceeded those of oral hypoglycaemic drugs (9%. Antimicrobials accounted for 10.2% of all drugs prescribed, of which 31.8% were quinolones. Drugs prescribed by generic name accounted for 11.98%. While all patients received antihypertensive therapy, more than a third were not on any antidiabetic treatment. Antihypertensive poly-therapy was observed in the majority with calcium channel blockers being most frequently prescribed antihypertensive drug class.

    2011-06-01

    Full Text Available Confronting an increasing EU opposition from a number of influential member states to its membership the AKP government adopted a multilateral approach to its foreign policy making resulting in dynamic economic and diplomatic policies with the countries from Asia, Africa, Latin America, and the Balkans region. In this article we analyzed the effects and consequences of a paradigmatic shift in Turkish foreign policy in the Western Balkans in relation to the country's EU membership prospects. Through its pro-active economic and diplomatic initiatives in the region Turkey has been proving itself as indispensable country for the European Union membership. Thus, if the Turkish government concentrates more on solving its internal problems and continues its pro-active diplomacy in Western Balkans, among other regions, it could become not only a regional but also a global power.

Majority of those species were described by dr. Stanko Karaman, the author who is, regarding the number of described species of European freshwater fishes, on the second place, just behind Carl Linnaeus. It is hardly believable that four trout species were formed in a small and oligotrophic microhabitat like Ohrid Lake, or three species in the Vardar River, knowing that the factor of geographic isolation doesn’t exist in either of the habitats. The author’s position is that all of these species are actually just types of one, highly plastic regarding the micro ecological conditions and phenotypic manifestations, species: Salmo trutta (Linnaeus, 1785. The author supports his opinion by his own results, as well the results of other scientists, obtained through studies of ecology and taxonomy of the brown trout in fluent and still water microhabitats. Also the author suggests that it is unacceptable to apply the terminology immanent to the anthropogenic factor in a sphere of another scientific area where such factor doesn't exist (agronomy-race and biology-natural selection.

    Full Text Available The world economic crisis that paralyzed the world economy in 2008 and 2009 had a profound impact on all countries in the world. Due to the interconnectedness of national economies the crisis spread rapidly from its centre in the United States to the world. There were two main transmission channels for the spread of the crisis between countries - international trade and the exchange of private capital between states in the form of foreign direct investment (FDI. This economic downturn has greatly influenced the domestic economic stability of the Western Balkan economies. The Western Balkan countries have shaped their economic policy towards European Union (EU membership, resulting in a high degree of liberalization in international economic relations accompanied by a commitment to free international capital movement. Since this region has close economic ties with the EU the crisis spread to the region very quickly, manifesting itself in decreasing regional exports to the EU market and a downward trend of FDI inflow to the region. This paper will focus on the impact of the world economic crisis on the Western Balkan economies and especially on their exports and FDI inflow. Our empirical analysis, based on panel data, uses a wider sample of Central and Eastern European Countries (CEEC which includes the Western Balkans, since we wanted to analyze if the effects of the economic crisis in the Western Balkans are specific or are common to most countries in transition. The analysis shows that Western Balkan exports have suffered due to the crisis, but reveals some interesting results on the different dynamics of export flows which depend on regional trade integration for their destination.

    Full Text Available The aim of the paper is to examine background knowledge about the orga­nizational properties of mobile pastoral groups in order to assess the likelihood of the existence of pastoral nomads in the Early Bronze Age in the central Balkans. The patterning found by A. L. Johnson (2002 is taken as a point of departure for the cross-cultural analysis conducted in this study. Johnson’s findings are in the main corroborated. Acquired knowledge about the workings of pastoral societies suggests that highly mobile pastoral groups should not be expected in the Early Bronze Age of the central Balkans.

  5. Neurology of endemic skeletal fluorosis

    2009-01-01

    Full Text Available Endemic skeletal fluorosis is widely prevalent in India and is a major public health problem. The first ever report of endemic skeletal fluorosis and neurological manifestation was from Prakasam district in Andhra Pradesh in the year 1937. Epidemiological and experimental studies in the endemic areas suggest the role of temperate climate, hard physical labor, nutritional status, presence of abnormal concentrations of trace elements like strontium, uranium, silica in water supplies, high fluoride levels in foods and presence of kidney disease in the development of skeletal fluorosis. Neurological complications of endemic skeletal fluorosis, namely radiculopathy, myelopathy or both are mechanical in nature and till date the evidence for direct neurotoxicity of fluoride is lacking. Prevention of the disease should be the aim, knowing the pathogenesis of fluorosis. Surgery has a limited role in alleviating the neurological disability and should be tailored to the individual based on the imaging findings.

  6. Tubular biomarkers to assess progression of diabetic nephropathy.

    Tramonti, Gianfranco; Kanwar, Yashpal S

    2011-05-01

    Despite aggressive management, many patients with diabetic nephropathy still develop end-stage renal disease. Accompanying tubulointerstitial damage is important in the progression of diabetic nephropathy. Markers of tubular damage, such as NGAL, KIM-1, and LFABP, have been proposed for monitoring the effectiveness of therapy. However, Nielsen et al. report a lack of an independent correlation between these biomarkers and glomerular filtration rate. Therefore, these markers seem to offer no improvement in the management of diabetic nephropathy. PMID:21527942

    The objective of this paper is to share experience and provide updated information on Capacity Development in the Central and Eastern Europe/Balkan Countries (CEE/BC) region relevant to public health nutrition, particularly in creation of food composition databases (FCDBs), applying dietary intake assessment and monitoring tools, and harmonizing methodology for nutrition surveillance. Balkan Food Platform was established by a Memorandum of Understanding among EuroFIR AISBL, Institute for Medical Research, Belgrade, Capacity Development Network in Nutrition in CEE - CAPNUTRA and institutions from nine countries in the region. Inventory on FCDB status identified lack of harmonized and standardized research tools. To strengthen harmonization in CEE/BC in line with European research trends, the Network members collaborated in development of a Regional FCDB, using web-based food composition data base management software following EuroFIR standards. Comprehensive nutrition assessment and planning tool - DIET ASSESS & PLAN could enable synchronization of nutrition surveillance across countries.

    Renal complications affect nearly 30–50% of adults with sickle cell anemia (SCA), causing significant morbidity and mortality. Standard renal function tests like serum creatinine and glomerular filtration rate become abnormal in this disease only when renal damage has become extensive and largely irreversible. Moreover, not all patients develop sickle nephropathy (SN). Therefore, noninvasive biomarkers that predict early onset of SN are necessary. We performed a cross-sectional analysis for n...

    Implication for health policy/practice/research/medical education: Much has been published on the epidemiology and clinicopathological characteristics of IgM nephropathy, but there is little information on the etiology,pathogenesis and specific therapy of the disease. Controversy still shrouds the definition and nosologic status of the disease. Well-coordinated and concerted international efforts and collaboration between researchers in the developing and developed countries are needed to make further progress on the above aspects of the disease.

    The benefits and risks of steroids for the treatment of IgA nephropathy remain uncertain. We systematically searched MEDLINE, EMBASE, and the Cochrane Library for randomized, controlled trials of corticosteroid therapy for IgA nephropathy published between 1966 and March 2011. We identified nine relevant trials that included 536 patients who had urinary protein excretion >1 g/d and normal renal function. Forty-six (8.6%) of these patients developed a kidney failure event, defined as doubling of the serum creatinine/halving of the GFR or ESRD. Overall, steroid therapy was associated with a lower risk for kidney failure (relative risk, 0.32 [95% confidence interval [CI], 0.15-0.67]; P=0.002) and a reduction in proteinuria (weighted mean difference, -0.46 g/d [95% CI, -0.63 to -0.29 g/d]), with no evidence of heterogeneity in these outcomes. Subgroup analysis suggested that the dose modifies the effect of steroids for renal protection (P for heterogeneity=0.030): Relatively high-dose and short-term therapy (prednisone >30 mg/d or high-dose pulse intravenous methylprednisolone with duration ≤1 year) produced significant renal protection, whereas low-dose, long-term steroid use did not. Steroid therapy was associated with a 55% higher risk for adverse events. The quality of included studies was low, however, limiting the generalizability of the results. In conclusion, steroids appear to provide renal protection in patients with IgA nephropathy but increase the risk for adverse events. Reliably defining the efficacy and safety of steroids in IgA nephropathy requires a high-quality trial with a large sample size. PMID:22539830

    Diabetes mellitus is the most common cause of chronic renal disorders and end-stage kidney disease in developed countries. It is the major cause of dialysis and transplantation. Failure in renal function causes wide disorders in the body. Diabetes results in wide range of alterations in the renal tissue. It is believed that early histological changes in diabetic nephropathy are detectable 2 years after diabetes is diagnosed. The glomerular alterations are the most important lesions in the diabetic nephropathy (DN). The Renal Pathology Society provides a new pathological classification for the detection of histopathology of DN. It divides diabetic nephropathy into four hierarchical glomerular lesions. Alloxan or streptozotocin induced diabetic rat is the one most widely used specie to study DN. Histological changes in the rat DN closely resemble the human disease and the most information of this review was obtained through the study of rat DN. All cell types of the kidney such as mesangial cells, podocytes and tubulointerstitial cells are liable to be affected in the event of DN. Severity of renal lesions is associated to the clinical aspect of renal outcome, but the aim of this article was only to review the histological changes of kidney in diabetes mellitus.

  13. “Early Classical Settlements” and the Iron Age of the Central Balkans: Issues of Ethnic Identity

    Directory of Open Access Journals (Sweden)

    Ivan Vranić

    2016-03-01

    Full Text Available In the Balkan archaeologies, ethnic identity has been traditionally treated as a stable and monolithic category, readily recognizable in the material culture. The issue of “ethnogenesis” of the Palaeo-Balkan “peoples” is the dominant topic and the basic research subject in culture-historical archaeology, today regarded as the consequence of the modern European nationalisms. Starting from the constructivist point, the paper seeks to examine the interpretations of ethnicity in the Balkan Iron Age, on the example of the so-called “early Classical settlements” – a series of mutually very similar fortified settlements located in the vast lands of the Balkan hinterland, today in the territory of several modern states. These settlements are broadly dated into the period from the 5th to the 3rd centuries BC, and have traditionally been interpreted as the final phase of the ethnogenesis of the Palaeo-Balkan communities, supposed to have been living in “tribal states”, whose population has been recognized as “people” or even “nation”. In the traditional literature, the ethnic characteristics have been readily recognized, projecting directly the modern socio-political structures onto the communities of the past that could have been founded on completely different group identity or political organization. The paper deals with the issue of the political aspects of these interpretations in various Balkan countries, favoring certain Palaeo-Balkan communities, and an attempt is made to contextualize these nationalistic narratives into the present.

  14. Project for study of seismic-hydrogeological phenomena in Balkan area

    International Nuclear Information System (INIS)

    The International Project of UNESCO - Bulgarian Academy of Sciences has the title 'Seismic - hydrogeological vulnerability of the geoenvironment and the population in the Balkan area'. The Project has a responsible task to make a study of the seismic-hydrogeological phenomena in seven Balkan countries. The study includes the collection of information for these phenomena, its analysis, documentation and comparison. The primary information will contribute also to solving several transboundary problems in the area. The obtained data will be applied for the creation of a database about the studied seismic-hydrogeological phenomena. It will be used for the primary mapping of established seismic-hydrogeological manifestations and supposed ones. On the basis of the obtained information we will go to the assessment of the seismic-hydrogeological vulnerability of the geological environment and the population in the investigated territories. The Project investigations could be used also for several recommendations related to the reduction of negative effects of the seismic-hydrogeological phenomena in seven Balkan countries. The Balkan experts will try to propose also more rational exploration of the rare positive effects of the seismic-hydrogeological manifestations. (authors)

    Goran Nikolić

    2013-11-01

    Full Text Available At the beginning of the 21st century there was a tendency of mild improvement of the quality of exports of Balkan countries, which can be traced through a slight increase in the share of goods of higher levels of processing (skill-intensive manufactures and medium- and high-tech products. In spite of that, the quality level of exports from Balkan economies lags greatly behind the countries in the EU and to a lesser extent the Central European economies in transition, with some signs of catching-up over time. The stagnant and relatively high levels of Export concentration ratio and low share of high processing goods are indicating that Balkan economies are increasingly specializing in price-sensitive markets.For export success it is of great importance to have the transfer of modern technology and investment, especially FDI, in competitive sectors which would 'spread' export offer. Improved approach to employment policy regulations and an extensive re-organization of science and education system is needed. One of the reasons for Balkan countries’ weak export lies in industrial policy, which would be able to promote innovation, product quality and high technological standards.

    2006-10-01

    Full Text Available The fragmentation of Yugoslavia has wrought extensive political and social changes in the Balkans and Europe more generally. After the collapse of communism and the breakup of Yugoslavia, many Balkan countries have transformed their political system and have begun to forge new foreign and security policy. Some of them have already joined the EU and NATO, and some are about to access these organizations. But the Western Balkan states seem to be farther in the future. In regard to the former Yugoslavia, the United States, European states and international organizations, such as the EU, NATO and UN, have attempted to engage and manage this breakup on an individual and collective basis. They have greatly influenced the process of the post-conflict nation building of this region. From this viewpoint, the paper discusses the political and social transformation of the Balkans after the breakup of the Yugoslav conflict, and the role of the EU and NATO in the process of the democratization and nation building in the former Yugoslavia. Moreover, attention is paid to the features of the involvement of the EU and NATO in the former Yugoslav conflict. In the process of Yugoslav fragmentation one can see the ‘Eastern Question’ revisited and the ‘Powder keg of Europe’ once again rising to its brim.

    Full Text Available The paper focuses on the current state of research and knowledge about ‘Balkan flint’ (hereinafter BF and trajectories flowing from the BF problem to the bigger and increasingly complex problem of the Neolithization of the eastern Balkans. The emergence and consolidation of the BF problem within the research agenda of specialists working on Balkan prehistory is briefly traced, as well as the confusing and inconsistently repetitive use of the term BF leading to some ‘mythologisation’ of the topic.A particular section of the paper represents the thoughts of the author on the conceptual meaning of BF in the context of the Balkan Neolithization debate, because until now its role has not been fully appreciated and recognized. Several theories and scenarios of the emergence and spread of the Neolithic in present-day Bulgaria are reviewed through the evidence of the particular Early Neolithic flint toolkits consisting in representative (retouched blades made from BF and attributed to the diagnostic features of the Early Neolithic package/culture.

  20. Inner Otherness as a Source of Fear: Elements of Horror in Balkan Travelogues

    Directory of Open Access Journals (Sweden)

    Sanja Lazarević-Radak

    2016-03-01

    Full Text Available Travel fiction has created numerous Others, assigning them an ontologically unstable status, while the traditional travelogue spread a fear of the dark interior of Europe, presenting images of daily political strife, assassinations, wars and uprisings. Just like the Gothic novel, which entertained its readers with images of ruins and gloomy structures in Eastern Europe, the travelogue spread a fear of the Balkans through Europe, depicting the Balkans as a place that could pose a threat to the entire continent. While enjoying the mysterious terror of the Gothic novel, Europe also derived a kind of pleasure from the shocking images that were to be found in travelogues from the Balkans. The paper re-examines the elasticity of the boundaries of the travelogue genre, and identifies convenient transformations of certain parts of the travelogue into text aimed at inspiring terror, shocking and appalling its readers. The transformations show that it is impossible to draw a strict boundary between travel fiction and travelogues, and at the same time reveal the hidden discourse used by both genres. The parallel presence of awareness of the geographic identity of the Balkans as European, and of the aspiration to depict them as the strange inner Otherness of Europe, is accompanied by the production of terrifying images. Although these images cannot be viewed solely as a threat of "reverse colonization", the assumption that hybridity is the basis on which the terrifying nature of the Balkans is produced is re-examined. The travelogue chapters, sections and illustrations assume the features of horror, particularly body horror, revealing Europe’s fear of the possibility of the Orient infiltrating the "body of the Occident", or of the possibility of the latter being infected by elements of "alien" i.e. Oriental culture.

  1. The complete genome sequence of a Crimean-Congo Hemorrhagic Fever virus isolated from an endemic region in Kosovo

    Full Text Available Abstract The Balkan region and Kosovo in particular, is a well-known Crimean-Congo hemorrhagic fever (CCHF endemic region, with frequent epidemic outbreaks and sporadic cases occurring with a hospitalized case fatality of approximately 30%. Recent analysis of complete genome sequences of diverse CCHF virus strains showed that the genome plasticity of the virus is surprisingly high for an arthropod-borne virus. High levels of nucleotide and amino acid differences, frequent RNA segment reassortment and even RNA recombination have been recently described. This diversity illustrates the need to determine the complete genome sequence of CCHF virus representatives of all geographically distinct endemic areas, particularly in light of the high pathogenicity of the virus and its listing as a potential bioterrorism threat. Here we describe the first complete CCHF virus genome sequence of a virus (strain Kosova Hoti isolated from a hemorrhagic fever case in the Balkans. This virus strain was isolated from a fatal CCHF case, and passaged only twice on Vero E6 cells prior to sequence analysis. The virus total genome was found to be 19.2 kb in length, consisting of a 1672 nucleotide (nt S segment, a 5364 nt M segment and a 12150 nt L segment. Phylogenetic analysis of CCHF virus complete genomes placed the Kosova Hoti strain in the Europe/Turkey group, with highest similarity seen with Russian isolates. The virus M segments are the most diverse with up to 31 and 27% differences seen at the nt and amino acid levels, and even 1.9% amino acid difference found between the Kosova Hoti and another strain from Kosovo (9553-01. This suggests that distinct virus strains can coexist in highly endemic areas.

    The clinical translation of established pathomechanisms of diabetic nephropathy improved the outcome in patients with diabetic nephropathy. However, they fail to halt or even reverse diabetic nephropathy, even though the feasibility of disease reversal has been established. The second part of this review summarizes recent novel insights into the mechanisms of diabetic nephropathy focusing on novel candidate mechanisms of diabetic nephropathy. These studies emphasize a crucial role of endothelial dependent mechanisms, which, however, can not be viewed as independent determinants of diabetic nephropathy. Rather, the endothelial dependent mechanisms act in concert with other cellular systems, establishing an intra-glomerular cross-talk which determines the progression of diabetic nephropathy.

  3. IRREGULAR MIGRATION FLOWS AND HUMAN TRAFFICKING IN THE WESTERN BALKAN COUNTRIES: CHALLENGES OF THE CONVERGENCE OF COUNTER-TRAFFICKING RESPONSE

    2016-05-01

    Full Text Available Irregular migration on the Western Balkan route has marked an unprecedented number during the last five years. Evidence indicates that both, non-European nationals and Western Balkan citizens have been involved in this complex migratory flow being exposed to various risks of human trafficking. But Western Balkan countries are source, transit and destination countries of human trafficking while their states are not well organized to implement a comprehensive and well-coordinated regional response to combat it. This paper aims at examining challenges faced by the Western Balkan countries to converge anti-trafficking response while facing increased irregular migratory waves. Using secondary data it illustrates various disparities and differences among them concluding that a well-coordinated, multi-faceted and integrated regional response is needed to combat this humanitarian problem.

    A 2-year-old girl was treated with gold salts for juvenile rheumatoid arthritis. Treatment had to be discontinued when persistent proteinuria was detected. As this case report indicates, close monitoring of the urine is mandatory during treatment with gold salts to detect early signs of toxicity: hematuria followed by casts and then proteinuria as therapy is continued. Histologic examination with electron microscopy will help to differentiate the different forms of gold toxicity. When the findings are consistent with gold-induced renal involvement, therapy should be discontinued. The gold nephropathy usually resolves in time, with no permanent renal damage.

    Colonoscopy is a commonly used procedure for colon cancer screening. The ideal bowel preparation for a good visualization of the colonic mucosa would be effective and well tolerated. Sodium phosphate (NaP) and polyethylen glycol (PEG) are the two most frequently used solutions in this indication. However, although NaP has been described as more effective and better tolerated, it can cause severe acute electrolytes disturbances and, in rare cases, lead to irreversible renal failure, called phosphate nephropathy. NaP should therefore be prescribed with caution and be formally banned for patients with risk factors. PMID:22400350

    Knowledge of past climate variability based on the study of paleoclimate archives may help in better understanding the forcing mechanisms and extent of any future climate change. In some regions, such as Eastern Europe, loess-paleosol sequences (LPS) are one of the most important terrestrial archives of Quaternary paleoclimate and its spatial and temporal dynamics. Studies of LPS from the Middle and Lower Danube basins fundamentally improved understanding of the European Quaternary climate and environmental evolution. The central Balkans (central Serbia) is situated in a transition zone between the temperate-continental climate zone to the north and Mediterranean climate to the south. Up to now this area has been poorly investigated concerning the paleoclimate evolution on a longer term, albeit this region is considered more sensitive to the relative influence associated to the Mediterranean climate influence than the Carpathian basin further north. To fill this gap we conducted a high-resolution multiproxy investigation on the Stalać LPS in the central Balkan (Serbia). Located at the southern limits of European loess distribution and within the Mediterranean climate influence, the Stalać section has potential for better understanding of past regional climate dynamics. We discuss grain-size (granulometric fractions, U-ratio), environmental magnetic (χ, χfd), geochemical (major and trace elements) and colour (L*, a*, b* values) data from the Stalać section in terms of switching sediment provenance sources modulated by past environmental conditions. We can show that the Carpathian Basin and central Balkans were influenced by different environmental conditions during past ~350 ka. A general higher continentality of the climate during the late Pleistocene can be observed over the Stalać section and the Carpathian Basin, indicating that this trend is more than a regional feature. Our results indicate warmer and/or more humid last glacial cycles compared to

    Full Text Available The conflict between France and Italy in the Balkans in fact was an attempt at reorganizing the Balkans and Central Europe following the disappearance of the Habsburg and Romanoff. The two Latin powers now had a unique opportunity to dictate a rearrangement of the Balkans, but their positions were diametrically opposed. Italy sought to establish domination in the Adriatic and the Balkans, whereas France sought to reorganize the region with the view to precluding Germany from recovering its former influence. At the same time, after Wilson’s political defeat in the Senate in 1919 Italian guarantees of the French-German border became vitally important to France. A compromise between Paris and Rome turned out to be unfeasible for several reasons. Expansionism of both the last liberal governments and Mussolini met with resolute opposition from Belgrade. Moreover, Paris was convinced that Italian domination not only would not bring stability to the Balkans, but on the contrary, that it would shatter the region’s Little Entente-based inner cohesion and facilitate Germany’s comeback. Thus most of diplomatic initiatives coming from Paris and Rome were mutually neutralized while German economic influence in the region irresistibly grew from the early 1930s. The agreement Mussolini-Laval reconciled the two Latin powers but it was now in the new circumstances created by the rise of Nazi Germany as a dominant force in Central Europe and the Balkans.

  10. Management of nephropathy in patients with type 2 diabetes

    Purpose To review evidence-based management of nephropathy in patients with type 2 diabetes. Data sources A literature search (MEDLINE 1966 to 2000) was performed using the key word “diabetic nephropathy". Relevant book chapters were also reviewed. Study selection Well-controlled, prospective landmark studies and expert review articles on diabetic nephropathy were selected. Data extraction Data and conclusions from the selected articles that provide solid evidence to the optimal management of diabetic nephropathy were extracted and interpreted in light of our clinical research experience with many thousands of Hong Kong Chinese patients. Results Hypertension, long diabetes duration, poor glycaemic control and central obesity are the most important risk factors. Microalbuminuria is a practical marker to predict overt nephropathy in type 2 diabetic patients. Risk factor modification, renal function monitoring and combined therapies are the current integrated approaches to manage patients with diabetic kidney disease. Optimal glycaemic control is the mainstay of treatment but effective antihypertensive therapy is also key to delaying the progression of diabetic nephropathy. Angiotensin-converting enzyme inhibitors and angiotensin Ⅱ receptor antagonists have important renoprotective actions independent of their blood pressure lowering actions. Conclusions Diabetic nephropathy is the leading cause of end-stage renal disease worldwide. Monitoring renal function and screening for microalbuminuria will allow the identification of patients with nephropathy at a very early stage for intervention. Tight glycaemic control and aggressive antihypertensive treatment as well as the use of renin-angiotensin system inhibitors should substantially delay the progression of nephropathy.

    Diabetic nephropathy(DN) is the leading cause of end stage renal disease in the Western world. Microalbuminuria(MA) is the earliest and most commonly used clinical index of DN and is independently associated with cardiovascular risk in diabetic patients. Although MA remains an essential tool for risk stratification and monitoring disease progression in DN, a number of factors have called into question its predictive power. Originally thought to be predictive of future overt DN in 80% of patients, we now know that only around 30% of microalbuminuric patients progress to overt nephropathy after 10 years of follow up. In addition, advanced structural alterations in the glomerular basement membrane may already have occurred by the time MA is clinically detectable.Evidence in recent years suggests that a significant proportion of patients with MA can revert to normoalbuminuria and the concept of nonalbuminuric DN is well-documented, reflecting the fact that patients with diabetes can demonstrate a reduction in glomerular filtration rate without progressing from normo-to MA. There is an unmet clinical need to identify biomarkers with potential for earlier diagnosis and risk stratification in DN and recent developments inthis field will be the focus of this review article.

  12. Minimizing the risk of chronic allograft nephropathy.

    Chronic allograft nephropathy, now defined as interstital fibrosis and tubular atrophy not otherwise specified, is a near universal finding in transplant kidney biopsies by the end of the first decade posttransplantation. After excluding death with functioning graft, caused by cardiovascular disease or malignancy, chronic allograft nephropathy is the leading cause of graft failure. Original assumptions were that this was not a modifiable process but inexorable, likely due to past kidney injuries. However, newer understandings suggest that acute or subacute processes are involved, and with proper diagnosis, appropriate interventions can be instituted. Our method involved a review of the primary and secondary prevention trials in calcineurin inhibitor withdrawal. Some of the more important causes of progressive graft deterioration include subclinical cellular or humoral rejection, and chronic calcineurin inhibitor toxicity. Early graft biopsy, assessment of histology, and changes in immunosuppression may be some of the most important measures available to protect graft function. The avoidance of clinical inertia in pursuing subtle changes in graft function is critical. Modification in maintenance immunosuppression may benefit many patients with early evidence of graft deterioration. PMID:19384181

    Full Text Available Diabetes is a major public health problem. Diabetes mellitus now affects large number of people in many developing countries than western countries where only two or three percent of the population is affected. With on estimated 33 million people in India alone affected by diabetes. It is a major epidemic of the twentieth century. Diabetes is a chronic disorder, which is associated with obesity, hypertension, advancing age, accumulation of harmful agents in the vascular endothelium causing development of microangiopathies or micro vascular complications. These complications include peripheral neuropathy, nephropathy and retinopathy, which cause early death and increased morbidity. These complications vary in prevalence in different populations depending on various factors such as genetic predisposition and ethnicity. Besides these complications cardiovascular changes are also occurring. Peripheral neuropathy (PN is characterized by pain, numbness, and tingling in the extremities with slow nerve conduction. Up to 50% of all patients with diabetes develop neuropathy and the prevalence of painful neuropathy ranges from 10 to 20% of patients with diabetes. Diabetic nephropathy is characterized by increased urinary protein, loss of renal function, excessive deposition of extracellular matrix proteins in the mesangium, and clear cytoplasm of the proximal tubular epithelial cells due to excessive reabsorbed glycogen. Evaluation of diabetes and its complications is very essential for proper control and prevention of the disease associated complications.

    Full Text Available Since Flannery, who showed that types and locations of storage facilities provide a variety of associations for explaining social change, the economic and social role of storage has been reviewed numerous times. So far, no research pertaining to storage practice has been conducted in the Central Balkans. However, storage strategies play an important role in the agricultural history of the region. Similar, or exactly the same storage techniques have been practiced from the Early Neolithic until modern times, and even today some are practiced by traditional farming communities. Hence this article, which is intended to lay the foundations for understanding the relation between economic and social processes as reflected by storage behaviour in the Late Neolithic-Early Eneolithic in the Central Balkans region.

    We remember the military medical practice of Croatian surgeon, Vatroslav Florschütz (1879-1967), known for his invention of the traction frame for repositioning bone fracture fragments of the upper and lower extremities. The method, known as the Balkan frame / beam or Balkan splint, was introduced and published in 1911 and used in war medicine thereafter. The memory of this invention adds to our orthopaedic heritage and sheds light on its creator working under the most demanding war circumstances. On the occasion of the 100th anniversary of the outbreak of World War I, reminiscence of Florschütz's war experience, his orthopaedic innovation and other innovations contributes to our understanding of human efforts to save lives and restore bodily function of the wounded during wars.

    Trichinella infections are endemic in the Balkan region of Europe. Though trichinellosis and agents thereof are serious problems for human health and animal husbandry, only a limited number of Trichinella isolates from Serbia have been identified at the species level so far. The aim of the present study was the surveillance and monitoring of Trichinella in domestic pigs and wild animals from the endemic district of Branicevo. Investigations performed during the 2009-2010 period revealed Trichinella infections in 344 out of 282,960 (0.12%) domestic pigs. Among wildlife, Trichinella infections were detected in 11 out of 94 (11.7%) wild boars (Sus scrofa), 7 out of 57 (12.3%) red foxes (Vulpes vulpes), 7 out of 13 (53.8%) golden jackals (Canis aureus), and in all three examined wolves (Canis lupus). Trichinella spiralis and Trichinella britovi were the only two species identified. T. britovi was identified in 31% of isolates from wildlife of the Branicevo district and T. spiralis was found in 53% of wild animals; mixed infections were observed in 16% of the animals examined. Findings form the basis of an information campaign for veterinary services, pig owners and the hunter's associations about the risk of the transmission of these zoonotic agents. The application of control programs as established at the Veterinary Specialist Institute of Pozarevac resulted in a decline in Trichinella infections among domestic pigs and the absence of human trichinellosis in the last three years in the Branicevo district.

    The contemporary distribution and genetic composition of biodiversity bear a signature of species' evolutionary histories and the effects of past climatic oscillations. For many European species, the Mediterranean peninsulas of Iberia, Italy and the Balkans acted as glacial refugia and the source of range recolonization, and as a result, they contain disproportionately high levels of diversity. As these areas are particularly threatened by future climate change, it is important to understand how past climatic changes affected their biodiversity. We use an integrated approach, combining markers with different evolutionary rates and combining phylogenetic analysis with approximate Bayesian computation and species distribution modelling across temporal scales. We relate phylogeographic processes to patterns of genetic variation in Myotis escalerai, a bat species endemic to the Iberian Peninsula. We found a distinct population structure at the mitochondrial level with a strong geographic signature, indicating lineage divergence into separate glacial refugia within the Iberian refugium. However, microsatellite markers suggest higher levels of gene flow resulting in more limited structure at recent time frames. The evolutionary history of M. escalerai was shaped by the effects of climatic oscillations and changes in forest cover and composition, while its future is threatened by climatically induced range contractions and the role of ecological barriers due to competition interactions in restricting its distribution. This study warns that Mediterranean peninsulas, which provided refuge for European biodiversity during past glaciation events, may become a trap for limited dispersal and ecologically limited endemic species under future climate change, resulting in loss of entire lineages.

    Application of new tools for epizootiological investigations in veterinary medicine, such as Geographical Information Systems (GIS), offers a new approach and possibilities for the eradication or control of infectious diseases. GIS is particularly useful for research conducted in small areas strongly impacted by man. Trichinellosis is a world-wide zoonosis, which is endemic in some European countries, Balkan district and Serbia in particular. There are very few data on GIS application in the field of trichinellosis. We here present the application of GIS for mapping Trichinella spp. occurrence and spatial and temporal patterns of Trichinello infection in one endemic district in Serbia. Settlements with trichinellosis were marked and particular points of interest were designated. Data on prevalence of Trichinella infection in domestic swine accompanied by location of foci indicated the existence of disease geographical stationarity. This first report on GIS application in Serbia will facilitate trichinellosis surveillance and monitoring of Trichinella spp. circulation among domestic pigs, and populations of synanthropic and sylvatic animals.

    Ancient lakes, with sediment records spanning >1 million years, are very rare. The UNESCO World Heritage site of Lake Ohrid in the Balkan region is thought to be the oldest lake in continuous existence in Europe and, with 212 endemic species described to date, is a hotspot of evolution. An international group of scientists working on a project entitled 'Scientific Collaboration on Past Speciation Conditions in Lake Ohrid (SCOPSCO)' realized a deep drilling campaign of Lake Ohrid in spring 2013. Based on several coring seismic campaigns between 2004 and 2011, Lake Ohrid became the target of an ICDP deep drilling campaign, with specific research aims: (i) obtain precise information about the age and origin of the lake, (ii) unravel the lake's seismotectonic history, (iii) obtain a continuous record of Quaternary volcanic activity and climate change, and (iv) investigate the influence of major geological/environmental events on evolution and the generation of extraordinary endemic biodiversity. Drilling began in April 2013 using the Deep Lake Drilling System (DLDS) of DOSECC (USA). The campaign, completed by late May, was deemed one of the most successful ICDP lake drilling projects, with a total of ~2100 m of sediment recovered from four different sites. At the central "DEEP" site, hydro-acoustic data indicated a maximum sediment fill of ca. 700 m, of which the uppermost 568 m was recovered. Coarse gravel and pebbles underlying clay and shallow water facies hampered deeper penetration. A total of 1526 m of sediment cores was collected from six boreholes, with a composite field recovery ('master core') of 544 m (95%). Three additional sites were drilled in order to analyze lake-level fluctuations, catchment dynamics, biodiversity and evolution processes ("Cerava", deepest drilled depth: 90 m), to investigate active tectonics and spring dynamics ("Gradiste", deepest drilled depth: 123 m), and to try to understand the geological origins of the Ohrid Basin ("Pestani

    Full Text Available Considering the common features in the resources field, but especially the way in which they have been managed at the level of each individual country, it can be stated that a destination such as the Balkan peninsula represents a culturally homogeneous space, which has been crystallized over centuries of common history and which has imprinted a “common” destiny to the member countries, regarding the economic and cultural development. Regarding natural resources, the main similarity resides in the existence of balneotherapy resources, with particular therapeutic properties, nowadays’ development being pressured by the deterioration of one’s conception about its own health (from the demand perspective, on the one hand, and extending the concept of health (from the supply perspective, on the other hand. In the context of a less-controlled development of certain methods/techniques/procedures by the stakeholders of wellness industry, it is necessary to maintain the authenticity of the balneotherapy product whose essence is the treatment. The purpose of the paper relies in establishing the common elements which could form the essence of the balneotherapy product (sui generis and, in the same time, the differentiation elements which form the developed product of each Balkan country, alongside with the establishment of joint actions, in order to set the coordinates of the regional balneotherapy marketing strategy for the Balkan peninsula.

    2008-06-15

    The Western Balkans - composed of Albania, Bosnia and Herzegovina, Croatia, the Former Yugoslav Republic of Macedonia, Montenegro, Serbia and Kosovo - is a complex region facing significant energy challenges. The conflicts over the break-up of the former Yugoslavia damaged much of the energy infrastructure and compounded the challenge of providing reliable energy supply. Electricity systems in many parts of the region remain fragile and in need of investment. A priority across the region is to put into place the institutions, infrastructure and policies that can support the provision of reliable, affordable and sustainable energy. For the Western Balkans as a whole, a key element of the reform effort is the Energy Community Treaty - a regulatory and market framework to which the entire region has now subscribed. This Treaty aims to create an integrated regional market for electricity and gas compatible with the European Union's internal energy market. This Energy Policy Survey is the first comprehensive review of energy policies and strategies in the Western Balkan region, and also covers important cross-cutting topics such as co-operation and energy trade, oil and gas transportation, and the links between energy and poverty. It identifies and assesses the reforms that are still needed to deliver efficient, modernised energy systems that can assist economic development, address energy poverty and reduce the environmental impacts of energy use.

    GABRIELA DUMBRAVĂ

    2014-12-01

    Full Text Available The paper examines the decisive impact of Romania’s Balkan heritage on its current position in the EU. Our study aims at proving that Romania’s present status among the EU countries is not only a matter of perception from the outside, but also a matter of self – perception, both being shaped by the stereotypes pertaining to the concept of ‘Balkanism’. Historically torn between the East and the West, the central and the liminal, the local and the global, the Balkan area has fostered a unique awareness of national identity, supported by a suspicious and defensive attitude towards the ‘outside’ and totally incongruent with the idea of integration. During the past years, the tension between its Balkan heritage and the integrative EU policies has generated a sense of identity crisis, due to which the Romanians find themselves “concomitantly inside and outside, actors in and audience at a play; owing to this ambiguity, they neither perform, nor watch very well”.

  17. Net capital flows to and the real exchange rate of Western Balkan countries

    Directory of Open Access Journals (Sweden)

    Gabrisch Hubert

    2015-01-01

    Full Text Available This paper uses Granger causality tests to assess the linkages between changes in the real exchange rate and net capital inflows using the example of Western Balkan countries, which have suffered from low competitiveness and external imbalances for many years. The real exchange rate is a measure of a country’s price competitiveness, and the paper uses two concepts: relative unit labour cost and relative inflation differential. The sample consists of six Western Balkan countries for the period 1996-2012, relative to the European Union (EU. The main finding is that changes in the net capital flows precede changes in relative unit labour costs and not vice versa. Also, there is evidence that net capital flows affect the inflation differential of countries, although to a less discernible extent. This suggests that the increasing divergence in the unit labour cost between the EU and Western Balkan countries up to the global financial crisis was at least partly the result of net capital inflows. The paper adds to the ongoing debate on improving cost competitiveness through wage restrictions as the main vehicle to avert the accumulation of current account imbalances. It shows the importance of changes in the exchange rate regime, reform of the interaction between the financial and the real sector, and financial supervision and structural change.

  18. Agricultural Support: Consequences of the Eventual Accession of the Balkan Countries to the Europe Union

    2008-06-01

    Full Text Available The author estimates the potential impact of the accession of seven Balkan countries (Albania, Croatia, Bosnia and Herzegovina, Macedonia, Montenegro, Serbia and Turkey to the EU on the agricultural direct payments and rural development expenditures disbursed from the EU budget. The estimation is based on the assumption that the agricultural support to GDP ratios are similar across member states at similar levels of development sharing a similar weight of agriculture in the economy. The results show that the annual additional burden for the 27 current EU members due to a Balkan enlargement would range between EUR 5 and 11.5 billion (in 2004 prices. The former figure reflects an agricultural support to GDP ratio corresponding to the average of the 12 new member states; the latter reflects the respective (average ratio of Bulgaria and Romania. In relative terms the Balkan enlargement would necessitate a net increase of the pool of transfers for direct payments and rural development expenditures in the range of 10% to 23%.

  19. THE WESTERN BALKANS BETWEEN INTERNAL TRANSITIONS AND THE EU INTEGRATION PROCESS

    Directory of Open Access Journals (Sweden)

    Elira LULI

    2015-12-01

    Full Text Available The Balkan region is still a “hot” zone where old legacies of the past interfere with the present and contribute to the transition processes of the countries there. The region seems committed to follow an EU-bound path, although it faces many challenges in terms of meeting the standards for EU and NATO membership. Somehow, persistent conflicts delay finding solutions. The difficult democratic transition, the lack of will and shallow political culture of regional elites delay the process of bringing these countries forward. This profound transition unfortunately occurs while the EU, on one hand, is trying to play the arbitrator part having promised to assume full leadership role and, on the other hand, tries to restrain the voices of those Euro-Sceptics who have been increasing their numbers recently. Meanwhile, a deterioration of the situation in the Balkans might have a negative impact across Europe and decrease the credibility of the EU as the main foreign policy and security actor in the whole region. This paper will first analyse the transition processes in the Balkans and the back and forth efforts to leave behind the past and head toward a common European perspective. Secondly, it will analyse the required active role of the EU and the urgency for a closer monitoring of the situation in this region. Thirdly, it emphasises the need to encourage public diplomacy in the region in order to mitigate conflicts and promote cooperation between the people there.

The chosen period provides a comparison for the model results with those estimated for the period up to 2007 in order to analyze changes caused by the global instability. According to the main findings of the paper, macroeconomic stabilization and structural reforms still matter in determining economic growth, but foreign direct investments and economic integrations seem to have the most important role in stimulating growth in the observed countries. Moreover, significant positive effects of foreign direct investments and economic integrations produce differences in growth paths between Emerging European and Western Balkan economies. Sharp decrease of foreign inflows in 2008 determined contractions of growth rates firstly in Emerging European economies with subsequent spill-over on the Western Balkan economies during 2009. Consequently, in the period of global instability, differences between two groups of economies become even more obvious.

    Full Text Available Unavailability of fast broadband internet access, primarily due to the lack of commercial interest of telecommunication operators, is the key reason for economic underdevelopment in rural areas in the Balkans. The process of developing broadband access in rural areas is multifaceted, complex and time-consuming. This paper analyses the current state of availability of broadband access in the Balkan countries, and investigates the algorithm with specific project phases and benefits of stakeholders at the national and local level. The purpose of the paper is to develop the model that rationalizes the implementation process of the broadband internet access projects, and to define the method of selecting an investment model for construction of broadband infrastructure. The results show that the Balkan countries have to start with preparatory activities and studies needed for successful implementation of the given model. This research contributes to stopping demographic and socio-economic degradation in less-developed areas, at the same time encouraging their development.

    Full Text Available The paper argues that the Balkans are not a single-type cultural- political and conflictogenic space where religions are the basic factor, but a heterogeneous zone made up of specific states, in each of which religion or religions have a specific positive cultural status and/or conflict potential (persistently or in certain period. The qualitative changes that have taken place in Christianity as a faith and an institution, both in the West and East (including the Balkans during the second half of the 20th century have shown that Christianity has become more dependent on and responsive to the fundamental cultural specificity of each particular society in which it exists. The thesis is emphasized that in the conflictual configuration of “Other” in the Balkans (of ethnic, nationalist, cultural type religion is not a pro-active factor but functions in interacting with a number of other factors (the Weberian idea of religious “strands”, coming to the fore in certain situations.

    The Balkans region sits at the transition between stable Eurasia and highly straining continental Eastern Mediterranean, resulting in a widespread seismicity and high seismic hazard. Because of intensive human and economic development over the last decades, the vulnerability has increased in the region faster than the progress in seismic hazard assessments. Opposite to the relatively good understanding of the seismicity in plate boundaries contexts, the seismic hazard is poorly known in the regions of distributed continental deformation like the Balkan region and is often underestimated (England and Jackson, 2011). Current seismic hazard assessments are based on the historical and instrumental catalogues. However, the completeness interval of the historical data bases may be below the average recurrence of individual seismogenic structures. In addition, relatively sparse seismological networks in the region and limited cross-border seismic data exchanges cast doubts in seismotectonic interpretation and challenge our understanding of seismic and geodynamic processes. This results in a inhomogeneous knowledge of the seismic hazard of the region to date. Geodetic measurements have the capability to contribute to seismic hazard by mapping the field of current active deformation and translating it into estimates of the seismogenic potential. With simple assumptions, measurements of crustal deformation can be translated in estimates of the average frequency and magnitude of the largest events and assessments of the aseismic deformation. GPS networks in the Balkans have been growing during the last few years mainly for civilian application (e.g. Cadastral plan, telecommunications), but opening new opportunities to quantify the present-day rates of crustal deformation. Here we present the initial results of GEOSAB (Geodetic Estimate of Strain Accumulation over Balkans), an AXA-Research-Fund supported project devoted to the estimation of crustal deformation and the

Angiotensin converting enzyme inhibitors and early corticosteroid usage are prime therapies. Tonsillectomy should be considered. Other components of a therapeutic cocktail could be; (a thromboxane antogonist, (b leukotriene antagonist, (c platelet activating factor antagonist, (d an anti-oxidant and (e an anti-fibrotic agent like pentoxyfylline. In the new millenium, there will be focus on anti-proliferative measures like platelets dependent growth factor aptamers. For unusual cases with rapid progression, the use of FK-506 or mycophenolate mofetil can be considered.

    Diabetic nephropathy can be regarded mainly as a type of microangiopathy, but is a disease that may also include aspects of macroangiopathy. This is especially true of renal disease in non-insulin dependent diabetes mellitus (NIDDM), which is characterized not only by diabetic glomerulosclerosis, but also by atherosclerosis. We performed morphological studies on the kidney, using computed tomography (CT), focusing on such points as: abdominal aortic calcifications at the level of kidney, calcifications in the renal artery, and wedge-shaped defects on the renal surface. We noted that these findings became more prominent in NIDDM patients during end-stage renal failure than during normal renal function, and were significantly more common in those two NIDDM groups than in age-matched nondiabetic patients without hypertension, hyperlipidemia or gout. NIDDM patients exhibited these features more frequently than IDDM patients. (author)

    Renal dysfunction in cholestatic liver disease is multifactorial. Acute kidney injury may develop secondary to renal vasoconstriction in the setting of peripheral vasodilation and relative hypovolemia, tubular obstruction by bile casts, and direct tubular toxicity from bile. Anabolic steroids are frequently used by athletes to boost endurance and increase muscle mass. These agents are a recently recognized cause of hepatotoxicity and jaundice and may lead to acute kidney injury. To increase awareness about this growing problem and to characterize the pathology of acute kidney injury in this setting, we report on a young male who developed acute kidney injury in the setting of severe cholestatic jaundice related to ingestion of anabolic steroids used for bodybuilding. Kidney biopsy showed bile casts within distal tubular lumina, filamentous bile inclusions within tubular cells, and signs of acute tubular injury. This report supports the recently re-emerged concept of bile nephropathy cholemic nephrosis. PMID:26587777

    Congenital obstructive nephropathy (ON) is one of the most frequent and complex diseases affecting children, characterized by an abnormal flux of the urine, due to a partial or complete obstruction of the urinary tract; as a consequence, urine may accumulate in the kidney and disturb the normal operation of the organ. Despite important advances, pathological mechanisms are not yet fully understood. In this contribution, the topology of complex networks, based on vectors of features of control and ON subjects, is related with the severity of the pathology. Nodes in these networks represent genetic and metabolic profiles, while connections between them indicate an abnormal relation between their expressions. Resulting topologies allow discriminating ON subjects and detecting which genetic or metabolic elements are responsible for the malfunction.

    Full Text Available Diabetic nephropathy (DN is one of the microvascular complications of both type 1 and type 2 diabetes, which is also associated with a poor life expectancy of diabetic patients. However, the pathogenesis of DN is still unclear. Thus, it is of great use to establish appropriate animal models of DN for doing research on pathogenesis and developing novel therapeutic strategies. Although a large number of murine models of DN including artificially induced, spontaneous, and genetically engineered (knockout and transgenic animal models have been developed, none of them develops renal changes sufficiently reflecting those seen in humans. Here we review the identified murine models of DN from the aspects of genetic background, type of diabetes, method of induction, gene deficiency, animal age and gender, kidney histopathology, and phenotypic alterations in the hope of enhancing our comprehension of genetic susceptibility and molecular mechanisms responsible for this disease and providing new clues as to how to choose appropriate animal models of DN.

    Full Text Available Doron Sudarsky, Eugenia NikolskyCardiology Department, Rambam Health Care Campus and Technion-Israel Institute of Technology, Haifa, IsraelAbstract: Development of contrast-induced nephropathy (CIN, ie, a rise in serum creatinine by either ≥0.5 mg/dL or by ≥25% from baseline within the first 2–3 days after contrast administration, is strongly associated with both increased inhospital and late morbidity and mortality after invasive cardiac procedures. The prevention of CIN is critical if long-term outcomes are to be optimized after percutaneous coronary intervention. The prevalence of CIN in patients receiving contrast varies markedly (from <1% to 50%, depending on the presence of well characterized risk factors, the most important of which are baseline chronic renal insufficiency and diabetes mellitus. Other risk factors include advanced age, anemia, left ventricular dysfunction, dehydration, hypotension, renal transplant, low serum albumin, concomitant use of nephrotoxins, and the volume of contrast agent. The pathophysiology of CIN is likely to be multifactorial, including direct cytotoxicity, apoptosis, disturbances in intrarenal hemodynamics, and immune mechanisms. Few strategies have been shown to be effective to prevent CIN beyond hydration, the goal of which is to establish brisk diuresis prior to contrast administration, and to avoid hypotension. New strategies of controlled hydration and diuresis are promising. Studies are mixed on whether prophylactic oral N-acetylcysteine reduces the incidence of CIN, although its use is generally recommended, given its low cost and favorable side effect profile. Agents which have been shown to be ineffective or harmful, or for which data supporting routine use do not exist, include fenoldopam, theophylline, dopamine, calcium channel blockers, prostaglandin E1, atrial natriuretic peptide, statins, and angiotensin-converting enzyme inhibitors.Keywords: contrast-induced nephropathy, contrast media

    AIM To determine the prevalence and incidence ofdiabetic nephropathy in Africa.METHODS: We performed a systematic narrativereview of published literature following the MOOSEGuidelines for Meta-Analysis and Systematic Reviewsof Observational Studies. We searched PubMed-MEDLINE for all articles published in English and Frenchlanguages between January 1994 and July 2014 usinga predefined strategy based on the combination ofrelevant terms and the names of each of the 54 Africancountries and African sub-regions to capture the largestnumber of studies, and hand-searched the referencelists of retrieved articles. Included studies reported onthe prevalence, incidence or determinants of chronickidney disease (CKD) in people with diabetes withinAfrican countries.RESULTS: Overall, we included 32 studies from 16countries; two being population-based studies andthe remaining being clinic-based surveys. Most of thestudies (90.6%) were conducted in urban settings.Methods for assessing and classifying CKD variedwidely. Measurement of urine protein was the mostcommon method of assessing kidney damage (62.5%of studies). The overall prevalence of CKD varied from11% to 83.7%. Incident event rates were 94.9% forproteinuria at 10 years of follow-up, 34.7% for endstagerenal disease at 5 years of follow-up and 18.4%for mortality from nephropathy at 20 years of followup.Duration of diabetes, blood pressure, advancingage, obesity and glucose control were the commondeterminants of kidney disease.CONCLUSION: The burden of CKD is importantamong people with diabetes in Africa. High quality datafrom large population-based studies with validatedmeasures of kidney function are still needed to bettercapture the magnitude and characteristics of diabeticnephropathy in Africa.

Ever since the birth of modern Balkan States (Greece, Bulgaria, Turkey and Serbia, urbanization, poverty and the frequent wars have been considered the major factors conducive to the spread of syphilis. The measures against sex work and sexually transmitted diseases (STDs were taken in two aspects, one medical and the other legislative. In this period, numerous hospitals for venereal diseases were established in the Balkan countries. In line with the international diagnostic approach and therapeutic standards, laboratory examinations in these Balkan hospitals included spirochete examination, Wassermann reaction, precipitation reaction and cerebrospinal fluid examination. Despite the strict legislation and the adoption of relevant laws against illegal sex work, public health services were unable to curb the spread of syphilis. Medical and social factors such as poverty, citizen’s ignorance of STDs, misguided medical perceptions, lack of sanitary control of prostitution and epidemiological studies, are highlighted in this study. These factors were the major causes that helped syphilis spread in the Balkan countries during the 19th and early 20th century. The value of these aspects as a historic paradigm is diachronic. Failure to comply with the laws and the dysfunction of public services during periods of war or socioeconomic crises are both factors facilitating the spread of STDs.

    Full Text Available There is no widely accepted definition or methods for measuring globalization and it is one of the most debatable phenomena in recent human history. The focus of this paper is, therefore, on globalization and methods of its measurement. The issue of measuring globalization inevitably involves numbers, and with the numbers one should always be careful, especially when dealing with something so complex and undefined. Also, the interpretation of results obtained by measuring globalization always requires additional interpretation. In this paper we examine the methods of measuring globalization from the macro aspect, i.e. at the level of countries, as well as the analysis of level of globalization in Western Balkan countries. As there is still an ongoing transition process in these countries, the application of globalization indices must be assessed in the overall context and complexity of transition process. The ultimate aim of this paper is to determine how to read and interpret globalization indices (indicators, and their informative power, as well as shortages in the case of transition countries such as the Western Balkans. Our results indicate that Western Balkan countries are not making sufficient progress in the transition process and they are thus not competitive. Therefore, a high degree of globalization does not imply that our countries a priori obtain the positive effects of globalization. We will try to define which additional indicators should be used when interpreting indicators of globalization for the countries of the region. The rationale behind this endeavor is the fact that the process of globalization and the process of transition present two interrelated processes for the countries of the region.

    2015-12-01

    Full Text Available This paper will focus on the policies developed by the European Union towards the Western Balkans, especially those related to human mobility and visa liberalization. The main target of the paper will be to show how the conditionality policies towards these countries have been developed related to security, geopolitical needs and interests, instead of the objective/technical criteria stated in the communitarian official documents. We will see how the last enlargements of the Union have affected considerably the different positions adopted by member states in their approach toward the Balkan countries, especially in relation to chapters 23 and 24 of the negotiation agreements, dealing with issues of Justice and Home Affairs. Since then, the pragmatic approach of the Union has been reinforced, so that the accession of candidates has been delayed in time. However, some things might change, if we take into consideration the current refugee and Ukraine crises, the new relationships that have been developed with Russia (especially by Serbia, and Greece’s approach towards Moscow on the verge of the economic crisis. If the European Union has, until now, followed a stick-and-carrot approach towards the Balkans in order to maintain a security belt on its southeast border, this approach might change within a new geopolitical context. In this paper we will analyse the visa liberalization process and its developments since Thessaloniki 2003, to show how the decisions taken by the Union have been more linked to political matters related to security than to technical reasons related to passport design.

  20. An Examination of Long-Term Environmental-Social Dynamics in the Balkans

    Kulkarni, C.; Boger, R. A.

    2015-12-01

    This study examines the interactions of environmental and social dynamics in Central Balkans over the past millennium, a period that experienced three major climatic phases (Medieval Climate Anomaly, Little Ice Age, and the warm 20th century). Meanwhile, the same period witnessed a complex human history with the emergence-rise-decline of the Ottoman Empire and subsequent socio-political events (e.g. wars, famines, migrations). Environmental datasets for the analysis include biological proxies (pollen, spores, and charcoal), geochemical signals through X-ray fluorescence (XRF), and a detailed chronology based on AMS 14C dating of two western and central Serbian lakes while social datasets include historic population data, land use, settlement patterns, and critical historic events derived from a review of the literature and local archives. Among the environmental datasets, indigenous tree and herbaceous pollen from these Central Balkans records demonstrate fluctuations in woodland-grassland dynamics whereas potassium and titanium counts obtained through XRF act as a proxy for surface erosion and clastic input into the lakes. Microscopic charcoal, cereal pollen and subordinate anthropogenic pollen (e.g. cultivated fruits and vegetables) are used to distinguish strong human impact over the landscape. These key anthropogenic indicators create a more thorough social component of the analysis in association with the social datasets. After reconstructing the individual time series for each environmental and social dataset, the two Central Balkan records are correlated in order to identify the environmental and social homogeneity and heterogeneity patterns occurring at shorter and longer timescales during the period. Results provide insights on how a region responds to social and environmental stressors and our approach demonstrates ways to integrate natural and social science system research.

  1. The environmental state of rivers in the Balkans--a review within the DPSIR framework.

    Skoulikidis, Nikolaos Th

    2009-04-01

    Fifteen major Balkan rivers with over 80% of the inflows in Eastern Mediterranean were examined for their environmental state within the DPSIR framework. Physicogeographic and hydrochemical conditions differ substantially among river basins, which may be roughly classified into three main zones. Despite strong fragmentation, most of the rivers are liable to flash floods and have low summer flow. Decreasing precipitation and (mis)management caused a dramatic discharge reduction over the last decades. Wars, political instability, economical crises over the past decades, combined with administrative and structural constraints, poor environmental planning and inspection and, frequently, a lack of environmental awareness imposed significant pressures on rivers. Large wetland areas were drained in favour of widespread intensive agriculture. The treatment of municipal wastewaters is barely adequate in Greece and insufficient elsewhere, while management and treatment of mining and industrial wastewaters is overall poor. In general, lowland river sections are hydro-morphologically modified and are at the greatest pollution risk, while upstream areas mostly retain their natural conditions. Nutrient concentrations in a number of central and eastern Balkan rivers often exceed quality standards, whereas pesticides and heavy metals, partly of geochemical origin, occasionally exceed quality standards. Reservoirs retain vast masses of sediments, thus adversely affecting delta evolution, while dam operation disturbs the seasonal hydrological and hydrochemical regimes. Almost all Balkan countries face daunting water resource challenges because of urgently needed investments in water supply, sanitation, irrigation, and hydroelectricity. International treaties and designations and European Union Directives have mobilized pollution mitigation and conservation efforts. However, the application of environmental legislation has proved in a number of cases inadequate. Constraints arise

    Diabetic nephropathy is the most frequent cause of terminal kidney failure in industrialized countries. In addition, the manifestation of diabetic nephropathy is associated with a poor prognosis for affected patients. Current therapies are based on established pathophysiological models. However, despite reflecting significant progress in our understanding of diabetic nephropathy, the translational efforts fell short their expectations. The current review summarizes recent studies which provided new insights into established mechanisms (part 1) and studies identifying new candidate mechanisms (part 2) underlying diabetic nephropathy.

    Full Text Available Phonological systems of the Balkan languages do not correspond to the Balkan language union borders, which can be explained by the difference between "intensive" (morphosyntactic and "extensive" (phonological language unions. In this case, we are dealing with the entrance of the Balkan languages into a wide transitional zone, stretching along the borders of East and Central Europe, and with the coinciding of their phonological systems with the system of Slavic languages known as vowel and consonant types. The same classification into two phonological systems exists in the Balkans too, and between them there are also two transitional borderlines. As known, the mediopalatal order of the "Macedonian" type [k', g', n', ľ] (q, gj, nj, l has been generalized in both the standard Albanian language and most of the Albanian dialects. Albanian [k', g', n', ľ] are, just like their Macedonian counterparts, semi-emancipated palatal correlates of basic [k, g, n, l], as proved by examples of their positional dephonologization and dialectal hardening /n'/ > /n/ [n%], when followed by front vowels. Both semi-soft [n%] and typically Albanian lateral opposition [ł-ŀ] confirm a palatal correlation of these phonemes existing also in the neighboring Serbian dialects. Albanian has undoubtedly affected the rise of these features, be it through an unilateral influence or merely through supporting different phonological development in these old-shtokavian dialects. On the other hand, the same could be said for the affrication of palatovelars [k', g'] > [č, ʒ(], which except in south-west region between Ishmi and Shkumbin, Elbasan and Tirana is present in all other branches of the Ghegian dialect. Wide distribution of this phenomenon excludes the possibility of one-sided Serbian influence while its character – reduction of palatovelars [k', g'] (q, gj and affricates [č, ʒ(] (ç, xh to one semi-soft affricate pair – has a typological and structural parallel in

    Full Text Available The aim of this paper is to review and critically evaluate relevant archaeological evidence regarding recent claims about the social complexity of Late Neolithic societies in the Central Balkans. Theory suggests that the relevant evidence should be related to population size, economic intensification, ranking, and craft specialisation. It is concluded that, although there are indications that inequalities existed and also demographic potential for organisational complexity, there is no unambiguous evidence that institutionalised inequality in the form of complex polities such as chiefdoms or states ever developed.

    2010-12-01

    Full Text Available The definition of areas of endemism is central to studies of historical biogeography, and their interrelationships are fundamental questions. Consistent hypotheses for the evolution of Pentatomidae in the Neotropical region depend on the accuracy of the units employed in the analyses, which in the case of studies of historical biogeography, may be areas of endemism. In this study, the distribution patterns of 222 species, belonging to 14 Pentatomidae (Hemiptera genera, predominantly neotropical, were studied with the Analysis of Endemicity (NDM to identify possible areas of endemism and to correlate them to previously delimited areas. The search by areas of endemism was carried out using grid-cell units of 2.5° and 5° latitude-longitude. The analysis based on groupings of grid-cells of 2.5° of latitude-longitude allowed the identification of 51 areas of endemism, the consensus of these areas resulted in four clusters of grid-cells. The second analysis, with grid-cells units of 5° latitude-longitude, resulted in 109 areas of endemism. The flexible consensus employed resulted in 17 areas of endemism. The analyses were sensitive to the identification of areas of endemism in different scales in the Atlantic Forest. The Amazonian region was identified as a single area in the area of consensus, and its southeastern portion shares elements with the Chacoan and Paraná subregions. The distribution data of the taxa studied, with different units of analysis, did not allow the identification of individual areas of endemism for the Cerrado and Caatinga. The areas of endemism identified here should be seen as primary biogeographic hypotheses.

    Vascular endothelium regulates vascular tone and maintains free flow of blood in vessels. Vascular endothelial dysfunction (VED) results in reduced activation of endothelial nitric oxide synthase (eNOS), reduced generation and bioavailability of nitric oxide (NO) and increased production of reactive oxygen species (ROS). The eNOS uncoupling in VED leads to eNOS mediated production of ROS that further damage the endothelial cells by upregulating the proinflammatory mediators and adhesion molecules. VED has been associated in the pathogenesis of hypertension, atherosclerosis, coronary artery diseases, diabetes mellitus and nephropathy. Diabetes is a chronic metabolic disorder characterized by hyperglycemia followed by micro and macrovascular complications. A correlation between diabetes and VED has been demonstrated in various studies. The downregulation of eNOS in diabetes has been noted to accelerate diabetic nephropathy. Moreover, various endogenous vasoconstrictors are also upregulated in diabetic nephropathy. VED has been shown to be involved in diabetic nephropathy by inducing nodular glomerulosclerosis followed by glomerular basement membrane thickness and mesangial expansion, which ultimately decline glomerular filtration rate (GFR). Thus it is suggested that diabetes-induced VED could be one of the culprits involved in the pathogenesis of diabetic nephropathy.

    Full Text Available Mona Singh, Akhenaton Pappoe, Burl R DonDivision of Nephrology, University of California Davis Medical Center, Sacramento, CA, USAAbstract: Pre-eclampsia is the most ominous complication of pregnancy, and primary glomerular diseases can mimic pre-eclampsia in presentation. A patient presented at 21 weeks gestation with signs and symptoms of both pre-eclampsia and primary glomerular nephropathy. A critical clinical decision whether to continue or terminate the pregnancy was dependent on results of a renal biopsy. The biopsy noted the presence of both pre-eclampsia and immunoglobulin A (IgA nephropathy. Thus, the onset of pre-eclampsia unmasked the presence of unrecognized IgA nephropathy, and the IgA nephropathy was a risk factor for this patient developing pre-eclampsia. The results of a renal biopsy are key in distinguishing pre-eclampsia from other kidney diseases and instituting appropriate clinical management.Keywords: proteinuria, IgA nephropathy, renal biopsy, pre-eclampsia

    Full Text Available Diabetic nephropathy (DN often develops in patients suffering from type 1 or type 2 diabetes mellitus. DN is characterized by renal injury resulting in proteinuria. Neuropilin-1 (NRP-1 is a single-pass transmembrane receptor protein devoid of enzymatic activity. Its large extracellular tail is structured in several domains, thereby allowing the molecule to interact with multiple ligands linking NRP-1 to different pathways through its signaling co-receptors. NRP-1’s role in nervous system development, immunity, and more recently in cancer, has been extensively investigated. Although its relation to regulation of apoptosis and cytoskeleton organization of glomerular vascular endothelial cells was reported, its function in diabetes mellitus and the development of DN is less clear. Several lines of evidence demonstrate a reduced NRP-1 expression in glycated-BSA cultured differentiated podocytes as well as in glomeruli from db/db mice (a model of type 2 Diabetes and in diabetic patients diagnosed with DN. In vitro studies of podocytes implicated NRP-1 in the regulation of podocytes’ adhesion to extracellular matrix proteins, cytoskeleton reorganization, and apoptosis via not completely understood mechanisms. However, the exact role of NRP-1 during the onset of DN is not yet understood. This review intends to shed more light on NRP-1 and to present a link between NRP-1 and its signaling complexes in the development of DN.

    2014-01-01

    As recently as 2002, most cases of primary membranous nephropathy (MN), a relatively common cause of nephrotic syndrome in adults, were considered idiopathic. We now recognize that MN is an organ-specific autoimmune disease in which circulating autoantibodies bind to an intrinsic antigen on glomerular podocytes and form deposits of immune complexes in situ in the glomerular capillary walls. Here we define the clinical and pathological features of MN and describe the experimental models that enabled the discovery of the major target antigen, the M-type phospholipase A2 receptor 1 (PLA2R). We review the pathophysiology of experimental MN and compare and contrast it with the human disease. We discuss the diagnostic value of serological testing for anti-PLA2R and tissue staining for the redistributed antigen, and their utility for differentiating between primary and secondary MN, and between recurrent MN after kidney transplant and de novo MN. We end with consideration of how knowledge of the antigen might direct future therapeutic strategies. PMID:24892704

  1. Histone Lysine Methylation in Diabetic Nephropathy

    2014-01-01

    Full Text Available Diabetic nephropathy (DN belongs to debilitating microvascular complications of diabetes and is the leading cause of end-stage renal diseases worldwide. Furthermore, outcomes from the DCCT/EDIC study showed that DN often persists and progresses despite intensive glucose control in many diabetes patients, possibly as a result of prior episode of hyperglycemia, which is called “metabolic memory.” The underlying mechanisms responsible for the development and progression of DN remain poorly understood. Activation of multiple signaling pathways and key transcription factors can lead to aberrant expression of DN-related pathologic genes in target renal cells. Increasing evidence suggests that epigenetic mechanisms in chromatin such as DNA methylation, histone acetylation, and methylation can influence the pathophysiology of DN and metabolic memory. Exciting researches from cell culture and experimental animals have shown that key histone methylation patterns and the related histone methyltransferases and histone demethylases can play important roles in the regulation of inflammatory and profibrotic genes in renal cells under diabetic conditions. Because histone methylation is dynamic and potentially reversible, it can provide a window of opportunity for the development of much-needed novel therapeutic potential for DN in the future. In this minireview, we discuss recent advances in the field of histone methylation and its roles in the pathogenesis and progression of DN.

    Full Text Available Introduction: Obesity, as a central piece inside metabolic syndrome, is associated with early chronic kidney disease (CKD. In addition, several observational, cross sectional, and longitudinal studies have demonstrated that obesity is as an independent risk factor for the onset, aggravated course, and poor outcomes of CKD including diabetic nephropathy. This implies that when obesity is reversed, many CKD risk factors and CKD itself could be favorably influenced. So all measures aimed at weight loss are recommended to minimize risks from obesity-related conditions and generate improvements in the metabolic profile. Recent evidence shows that bariatric surgery (BS can revert or improve proteinuria and CKD in morbidly obese patients. Objectives and methods: The present review is aimed to provide the evidence regarding the beneficial effects of weight loss after BS in different stages of CKD including kidney transplant recipients, with an special focus on the beneficial effect in reducing or improving proteinuria and renal failure. Furthermore, this updated systematic review of the literature analyzes potential adverse effects that BS could induce not only on renal function but also on morbidity and mortality risk in perioperative and postoperative period. Conclusions: Results from the different case reports, meta analysis as well as systematic review of clinical trials show that obesity treatment by way of lifestyle changes, pharmacotherapies and BS can reduce proteinuria and help to prevent loss of renal function. Also BS may reduce complications, and allow obese patients with end-stage renal disease to undergo kidney transplantation with good results.

    The aim of this study was to explore physical self-concept of adolescents of the Western Balkans (Serbia, Slovenia, Croatia, and Bosnia and Herzegovina) according to sex and country. The participants were 2,606 students, ages 13 and 14 years (M = 13.5, SD = 0.9). The Physical Self-Description Questionnaire (PSDQ) was used to assess multidimensional physical self-concept. The results show the interaction of sex and country for three dimensions of physical self-concept (Appearance, Global Physical Self-Concept, and Self-Esteem). It was shown that female and male adolescents' perception of physical appearance, self-esteem, and global physical self-concept is more susceptible to influences of socio-cultural factors in the monitored countries. In all other dimensions of Physical self-concept, sex differences were consistently manifested in favour of male adolescents, except in Flexibility. Regardless of adolescents' sex, under the increasing influence of Western culture in the Western Balkan countries, adolescents more critically evaluate their body and motor abilities. PMID:25310227

    An investigation was performed to assess a possible health risk of depleted uranium (DU) for residents and German peacekeeping personnel serving on the Balkans. In order to evaluate a possible DU intake, the urinary uranium excretions of volunteers were collected and analysed using inductively coupled plasma mass spectrometry (ICP-MS). In total, more than 1300 urine samples from soldiers, civil servants and unexposed controls of different genders and ages were analysed to determine uranium excretion parameters. All participating volunteers, aged 3-92 y, were grouped according to their gender and age for evaluation. The results of the investigation revealed no significant difference between the unexposed controls and the peacekeeping personnel. In addition, the geometric means of the daily urinary excretion in peacekeeping personnel, ranging from 3 to 23 ng d(-1) for different age groups, fall toward the lower end of renal uranium excretion values published for unexposed populations in literature. The measured data were compared with the International Commission on Radiological Protection prediction for the intake of natural uranium by unexposed members of the public. The two data sets are in good agreement, indicating that no relevant intake of additional uranium, either natural or DU, has appeared for German peacekeeping personnel serving on the Balkans.

    Full Text Available The gradual development of the primary copper metallurgy in Balkans starts with production of small jewelry pieces and ends with the serial production of massive tools and weapons. It is confirmed that this metallurgy depended on the contemporary mining, i.e. the available sources of the raw materials. It is also corroborated by the discovery of two Early Eneolithic copper mines: Rudna Glava in Eastern Serbia and Ai-Bunar in Bulgaria /first half and the middle of the 5th millennium BC/. These mines are also the evidence for the local exploitation of the carbonate copper minerals - malachite and azurite. The technology employed is close to the former flint mining in the Late Neolithic; massive pebbles obtained from the neighboring alluvial deposits were used as mining hammers. Identical technology was employed in the mines dating from the later periods /Rudnik, Central Serbia, Jarmovac, Priboj na Limu/. The Vinča culture of the central Balkan followed all metallurgical phases of introduction of metal and use of the carbonate ores /Gradac I - III phase/. This long process of including the metal in wider use lasted generally from the middle of the 5th millennium BC to the end of the 4th millennium BC, i.e. to the appearance of the Bronze Age.

    Full Text Available This article highlights the political merit natural sciences were awarded under the totalitarian regime of Nazi Germany and their propagandistic role in Hitler's foreign policy agenda for the Balkans, a region which was expected to replace Germany's colonies lost in World War I. It accounts further for the policies and strategies National Socialists used to exert cultural influence on the countries of South-East Europe, namely through a number of institutions with which natural sciences were in one way or another involved in order to promote German culture abroad. The promotion of the German language and, to a certain degree, the Nazi ideology was a precondition for familiarising the Balkan countries with German scientific achievements, which would pave the way for an economic and political infiltration in that region. Therefore, natural sciences, as part of the German intellect, acquired political and economic connotations hidden behind the euphemistic term of cultural policy, designed for this region of geopolitical importance. The article is based almost exclusively on unpublished German records.

    Full Text Available After the Cold War, the Western Balkan countries have become an important laboratory for the EU, able to exert its EU crises management and transformative power. Through restoring stability in the region, overcoming ethno–territorial and inter–ethnic conflicts, improving regional cooperation, consolidating democracy, building democratic institutions and promoting market economy, EU’s goal was to make war unthinkable in this region. Referring to the definition of peacebuilding as ‘action to identify and support structures which tend to strengthen and solidify peace to avoid a relapse into conflicts’, this paper tries to explore whether, how and to what extent, EU has contributed as a peacebuilder in the Western Balkans, using crises management operations and mission and enlargement policy. It argues that both these instruments can be considered equally relevant as, on the one hand they create favourable conditions for lasting peace, security and stability in the region and on the other hand, through enlargement policy they push this region towards political and institutional reform, economic reforms and regional cooperation.

    Full Text Available After the restoration of Serbia in 1830, the areas of medieval Serbia left out of her borders were dubbed Old Serbia - Kosovo, Metohija, Rascia (the former sanjak of Novi Pazar and the neighbouring areas. Old Serbia (from 1877 onwards the vilayet of Kosovo was dominated by local Albanian pashas, whereas the Christian Orthodox Serbs and their villages were attacked and pillaged by Muslim Albanian brigands. The religious antagonism between Muslims and Christians expanded into national conflict after the 1878 Albanian League had claimed the entire “Old Serbia for Greater Albania”. The position of Christian Orthodox Serbs, who accounted for a half of the population at the end of the nineteenth century, was dramatically aggravated due to Muslim Albanians' tribal anarchy, Austria-Hungary's pro-Albanian agitation and, after 1908, frequent Albanian rebellions. All efforts of Serbia to reach a peaceful agreement with Muslim Albanian leaders in Old Serbia before the First Balkan War had ended in failure. The First Balkan War was the most popular war in Serbia’s history as it was seen as avenging the 1389 Battle of Kosovo which had sealed the Ottoman penetration into the Serbian lands. In October 1912, Serbia liberated most of Old Serbia, while Montenegro took possesion of half of the Rascia area and the whole of Metohija. While the decimated and discriminated Serb population greeted the Serbian and Montenegrin troops as liberators, most Albanians, who had sided with the Ottomans, saw the establishment of Serbian rule as occupation.

    Researchers agree that domesticated plants were introduced into southeast Europe from southwest Asia as a part of a Neolithic "package," which included domesticated animals and artifacts typical of farming communities. It is commonly believed that this package reached inland areas of the Balkans by ∼6200 calibrated (cal.) BC or later. Our analysis of the starch record entrapped in dental calculus of Mesolithic human teeth at the site of Vlasac in the Danube Gorges of the central Balkans provides direct evidence that already by ∼6600 cal. BC, if not earlier, Late Mesolithic foragers of this region consumed domestic cereals, such as Triticum monococcum, Triticum dicoccum, and Hordeum distichon, which were also the main crops found among Early Neolithic communities of southeast Europe. We infer that "exotic" Neolithic domesticated plants were introduced to southern Europe independently almost half a millennium earlier than previously thought, through networks that enabled exchanges between inland Mesolithic foragers and early farming groups found along the Aegean coast of Turkey.

  10. The influence of climate change to European Lakes, with a special emphasis in the Balkan Region

    International Nuclear Information System (INIS)

    There are almost one and half million lakes in Europe, if small water bodies with an area down to 0.001 km2 are included. The total area of lakes is over 200.000 km2, in addition the man-made reservoirs cover almost 100.000 km2. The largest lakes are located in the zone extending from southwestern Sweden through Finland to Russia, but there are many important lakes also in central and southern Europe. The Balkan countries have altogether about ten thousand lakes with a total area of over 4000 km2 and total volume of almost loo km3. Over half of the total volume is in Lake Ohrid, which ranks the seventh in Europe both as to the volume and as to the maximum depth. However, there are around thirty lakes in Europe with their surface area larger than that of Lake Ohrid. In addition to the lakes, the Balkan countries also have thousands of reservoirs with a total water storage capacity of over 50 km3. The response of European lakes to climate change can be discussed by dividing the lakes into five categories: 1) deep temperate lakes, 2) shallow temperate lakes, 3) mountain lakes, 4) boreal lakes and 5) arctic lakes. The lakes in the Balkan region fall belong into the first three categories. Most of the deep temperate lakes are warm monomictic; convective overturn occurs in winter or early spring. The future climate change may suppress this overturn, giving these lakes the classification of oligomictic. This implies the enhancement of anoxic bottom conditions and an increased risk of eutrophication. The oxygen conditions can also be expected to deteriorate due to increased bacterial activity in deep waters and superficial bottom sediment. In shallow temperate lakes, higher water temperatures in the future will induce intensified primary production and bacterial decomposition. The probability of harmful extreme events, e.g. the mass production of algae, will increase. The impacts may extend to fishing and recreational use. In lakes with relatively long water retention

  11. Adaptive changes in renal mitochondrial redox status in diabetic nephropathy

    International Nuclear Information System (INIS)

    Nephropathy is a serious and common complication of diabetes. In the streptozotocin (STZ)-treated rat model of diabetes, nephropathy does not typically develop until 30 to 45 days post-injection, although hyperglycemia occurs within 24 h. We tested the hypothesis that chronic hyperglycemia results in a modest degree of oxidative stress that is accompanied by compensatory changes in certain antioxidants and mitochondrial redox status. We propose that as kidneys progress to a state of diabetic nephropathy, further adaptations occur in mitochondrial redox status. Basic parameters of renal function in vivo and several parameters of mitochondrial function and glutathione (GSH) and redox status in isolated renal cortical mitochondria from STZ-treated and age-matched control rats were examined at 30 days and 90 days post-injection. While there was no effect of diabetes on blood urea nitrogen, measurement of other, more sensitive parameters, such as urinary albumin and protein, and histopathology showed significant and progressive worsening in diabetic rats. Thus, renal function is compromised even prior to the onset of frank nephropathy. Changes in mitochondrial respiration and enzyme activities indicated existence of a hypermetabolic state. Higher mitochondrial GSH content and rates of GSH transport into mitochondria in kidneys from diabetic rats were only partially due to changes in expression of mitochondrial GSH carriers and were mostly due to higher substrate supply. Although there are few clear indicators of oxidative stress, there are several redox changes that occur early and change further as nephropathy progresses, highlighting the complexity of the disease. Highlights: ►Adaptive changes in renal mitochondrial and redox status in diabetic rats. ►Modest renal dysfunction even prior to onset of nephropathy. ►Elevated concentrations of mitochondrial GSH in diabetic kidneys. ►Change in GSH due partly to increased protein expression of transporter.

    Diabetic nephropathy represents a condition frequently detected in current clinical practice characterized by a very high cardiovascular risk profile. Blood pressure reduction via antihypertension drug treatment represents a therapeutic approach capable of exerting favorable effects on renal and cardiovascular outcomes. The purpose of this article is to review the current literature and results of key clinical trials pertaining to blood pressure goals of antihypertension treatment in these patients. The pros and cons of a less or a more intensive blood pressure goal in diabetic nephropathy will be discussed, with particular emphasis on the cardiovascular and renal effects of each therapeutic strategy.

    Burkina Faso, through the works of many teams of the OCCGE based in Bobo-Dioulasso, has signi-ficant data on several tropical endemics of which schistosomiasis. With the complementary works, it appears to be possible to establish a distribution of the schistosomiasis which reveals its importance. It will be the first stage of the planned national control program. The parasitologic data-gathering which covers the period of 1951 to 2000, used all the standard techniques.

All the eleven medical areas of the country have many sites submitted to parasitologic investigation. As regard the distribution of the two parasites involved with man (Schistosoma haematobium and S. mansoni), the data of prevalence (1% to 100%) and their distribution confirm their endemicity and the focal transmission. S. mansoni is located in eight medical areas particularly in the South and the West. S. haematobium is present in all the eleven medical areas of the country. In hydraulic planning as Sourou where the prevalences went from 23% to 70% for S. haematobium and from 0% to 69% for S. mansoni between 1987 and 1998. The situation requires a continuous monitoring. The spatial distribution of the six species of intermediate hosts shows that Bulinus truncatus and B. senegalensis Soudano-Sahelian species are present in all the ecological zones. B. globosus and Biomphalaria pfeifferi meet preferentially in the southern half of the country which reinforces the observation according to which the 14th northern parallel is often considered as the limit of septentrional extension of these two species. The other species Bulinus forskalii and B umbilicatus could have preference areas. All the species show a certain affinity with a type of biotope. The rarity and temporary aquatic systems lead to a

    Full Text Available Beginning with the concept of "nesting orientalism" introduced by Milica Bakić-Hayden in the sense of patterns of representation used to describe the Other by all ethnic groups in former Yugoslavia, this paper examines four views of "nesting balkanism" in post-Yugoslav literature. First, there is a chronotopic view from the post-Yugoslav exile back to the past, in which the Balkans function as a contextual synonym for the "former homeland," always used in a context of "war," "violence," "primitivism," "disorder" and "cruelty". The second view refers to several Slovenian authors, starting with Slavoj Žižek, Aleš Debeljak and the young novelist Goran Vojnović, who show specific balkanistic representation connected with sevdah and turbofolk music. The third view is connected with travelling and trains, as a frequent topic of orientalistic representation inherited from the Orient Express novels. Finally, the fourth view draws on examples from Dubravka Ugrešić’s descriptions of her "fellow-countrymen." Almost all analyzed examples show that using the name Balkan in post-Yugoslav literature is connected with the "logic of displaced racism," a practice regarded by Žižek as a kind of inverted racism which is allowed when comparing "tolerant" Europe to Balkan Otherness.

  1. Constant diversification rates of endemic gastropods in ancient Lake Ohrid: ecosystem resilience likely buffers environmental fluctuations

    Ancient lakes represent key ecosystems for endemic freshwater species. This high endemic biodiversity has been shown to be mainly the result of intra-lacustrine diversification. Whereas the principle role of this mode of diversification is generally acknowledged, actual diversification rates in ancient lakes remain little understood. At least four types are conceivable. Diversification rates may be constant over time, they may fluctuate, rates may be higher in the initial phase of diversification, or there may be a pronounced lag phase between colonization and subsequent diversification. As understanding the tempo of diversification in ancient lake environments may help reveal the underlying processes that drive speciation and extinction, we here use the Balkan Lake Ohrid as a model system and the largest species flock in the lake, the non-pyrgulinid Hydrobiidae, as a model taxon to study changes in diversification rates over time together with the respective drivers. Based on phylogenetic, molecular-clock, lineage-through-time plot, and diversification-rate analyses we found that this potentially monophyletic group is comparatively old and that it most likely evolved with a constant diversification rate. Preliminary data of the SCOPSCO (Scientific Collaboration On Past Speciation Conditions in Lake Ohrid) deep-drilling program do indicate signatures of severe environmental/climatic perturbations in Lake Ohrid. However, so far there is no evidence for the occurrence of catastrophic environmental events. We therefore propose that the constant diversification rate observed in endemic gastropods has been caused by two factors: (i) a potential lack of catastrophic environmental events in Lake Ohrid and/or (ii) a probably high ecosystem resilience, buffering environmental changes. Parameters potentially contributing to the lake's high ecosystem resilience are its distinct bathymetry, ongoing tectonic activities, and karst hydrology. The current study not only

  3. Alteration in serum osteocalcin levels in patients with diabetic nephropathy

    International Nuclear Information System (INIS)

    The fact that bone mass density (BMD) is not useful for assessing fracture risk in diabetic patients (DM) seems problematic, because those populations are increasing in every country. Osteocalcin (OC) is synthesized by osteoblasts and is considered to be a marker of bone formation. The present study was carried out to evaluate the usefulness of OC as noninvasive biomarker of bone formation in diabetes mellitus type 2 (uncomplicated) and diabetic nephropathy. Immunoradiometric assay(IRMA) was used for the quantitative measurement of human intact OC both N-terminal and C-terminal fragments in the serum of the control and the studied groups. OC levels in the uncomplicated diabetic group were significantly lower while in the diabetic nephropathy group was significantly higher compared to control values . There was a weak negative correlation between OC and both fasting blood glucose and glycated Hb% in the diabetic group. In diabetic nephropathy patients, a weak positive correlation was observed between OC and protein creatinine ratio. The results concluded that changes in bone remodelling marker OC are present in both DM type 2 and diabetic nephropathy explaining osteopenia and osteoporosis observed in both cases.Therefore, an effective glycaemic control should be the hallmark of prevention and treatment of diabetes mellitus induced osteoporosis

    We previously showed that the transcription factor Mafb is essential for podocyte differentiation and foot process formation. Podocytes are susceptible to injury in diabetes, and this injury leads to progression of diabetic nephropathy. In this study, we generated transgenic mice that overexpress Mafb in podocytes using the nephrin promoter/enhancer. To examine a potential pathogenetic role for Mafb in diabetic nephropathy, Mafb transgenic mice were treated with either streptozotocin or saline solution. Diabetic nephropathy was assessed by renal histology and biochemical analyses of urine and serum. Podocyte-specific overexpression of Mafb had no effect on body weight or blood glucose levels in either diabetic or control mice. Notably, albuminuria and changes in BUN levels and renal histology observed in diabetic wild-type animals were ameliorated in diabetic Mafb transgenic mice. Moreover, hyperglycemia-induced downregulation of Nephrin was mitigated in diabetic Mafb transgenic mice, and reporter assay results suggested that Mafb regulates Nephrin directly. Mafb transgenic glomeruli also overexpressed glutathione peroxidase, an antioxidative stress enzyme, and levels of the oxidative stress marker 8-hydroxydeoxyguanosine decreased in the urine of diabetic Mafb transgenic mice. Finally, Notch2 expression increased in diabetic glomeruli, and this effect was enhanced in diabetic Mafb transgenic glomeruli. These data indicate Mafb has a protective role in diabetic nephropathy through regulation of slit diaphragm proteins, antioxidative enzymes, and Notch pathways in podocytes and suggest that Mafb could be a therapeutic target.

    The following definition is one frequently used about globalization: "Globalization represents the process through which geographical distance becomes a less important factor concerning the development and stability of socio-cultural, political and economic cross border relations". Globalization is considered to be a two way process: the world is integrating, is globalizing but in the same time it becomes more and more differentiated, it becomes regionalized.

  13. Predicting diabetic nephropathy using a multifactorial genetic model.

    Ilana Blech

    Full Text Available AIMS: The tendency to develop diabetic nephropathy is, in part, genetically determined, however this genetic risk is largely undefined. In this proof-of-concept study, we tested the hypothesis that combined analysis of multiple genetic variants can improve prediction. METHODS: Based on previous reports, we selected 27 SNPs in 15 genes from metabolic pathways involved in the pathogenesis of diabetic nephropathy and genotyped them in 1274 Ashkenazi or Sephardic Jewish patients with Type 1 or Type 2 diabetes of >10 years duration. A logistic regression model was built using a backward selection algorithm and SNPs nominally associated with nephropathy in our population. The model was validated by using random "training" (75% and "test" (25% subgroups of the original population and by applying the model to an independent dataset of 848 Ashkenazi patients. RESULTS: The logistic model based on 5 SNPs in 5 genes (HSPG2, NOS3, ADIPOR2, AGER, and CCL5 and 5 conventional variables (age, sex, ethnicity, diabetes type and duration, and allowing for all possible two-way interactions, predicted nephropathy in our initial population (C-statistic = 0.672 better than a model based on conventional variables only (C = 0.569. In the independent replication dataset, although the C-statistic of the genetic model decreased (0.576, it remained highly associated with diabetic nephropathy (χ(2 = 17.79, p<0.0001. In the replication dataset, the model based on conventional variables only was not associated with nephropathy (χ(2 = 3.2673, p = 0.07. CONCLUSION: In this proof-of-concept study, we developed and validated a genetic model in the Ashkenazi/Sephardic population predicting nephropathy more effectively than a similarly constructed non-genetic model. Further testing is required to determine if this modeling approach, using an optimally selected panel of genetic markers, can provide clinically useful prediction and if generic models can be

  14. On problems related to the deployment of depleted uranium weapons in the Balkans

    International Nuclear Information System (INIS)

    The likely long-term environmental and health effects of the deployment of weapons containing depleted uranium (DU) in the Balkans are discussed. To determine whether depleted uranium or spent reactor fuel was used in the weapons, knowledge is required of the 235 U to 238 U activity (or concentration) ratio in the measured samples. To this end, and to distinguish between uranium originating from natural and man-made sources, we discuss some of the methodology and metrology issues involved in performing alpha- and gamma- spectrometry of uranium in environmental and human samples. We present results of nuclear spectrometry performed on DU core deposits from the aluminium jacket of a PGU-14 bullet found in South Serbia. We draw attention to aspects involving ionising radiation, which are likely to be of importance when formulating a prognosis of the possible environmental and health impact of the deployment of DU weapons, indicating the importance of the inhalation pathway in children.

    Full Text Available During the past centuries the city of Prizren has persisted as a unique multiethnic and multicultural environment atypical even for the Balkans, well-known for its ethnic, linguistic, cultural and religious diversity. Various nations used to live and pass through Prizren in the course of more than six centuries – the Serbs Turks, Albanians, Aromanians, Greeks and others – leaving their specific marks, visible on the city itself as well as the life and the mentality of its inhabitants. One of the most vivid testimonies to this long-term coexistence can be seen in vernaculars of the local population. This paper presents some Albanian loan-words from the Serbian speech of Prizren hitherto not registered (or not recognised as such in the respective etymological dictionaries and linguistic studies. The aim of this work is to offer their etymological analysis, through an investigation of the ways and mechanisms of lexical borrowing in the limited area of this town and to observe this phenomenon in a broader Balkan perspective.

    Due to the limited access to kidney transplantation (KTx) in developing countries, desperate patients have engaged in the purchase and sale of kidneys. In 2004, the World Health Assembly urged member states to protect the poor and vulnerable from being exploited through practices of illegal organ trafficking that had become widespread throughout the world. In 2008, the international transplant community convened a summit of transplant professionals, legal experts and ethicists to combat organ trafficking, transplant tourism and transplant commercialism that resulted in the Declaration of Istanbul (DOI). The South-Eastern Europe Health Network (SEEHN) represents a nine country multigovernmental collaboration on health systems. The Regional Health Development Centre on Organ Donation and Transplant Medicine (RHDC) was established in 2011 in Croatia to facilitate cooperation among south-eastern European countries to improve organ transplantation within the Balkan region. Since 2011, a collaboration between the RHDC, the Custodian Group of the DOI (DICG) and SEEHN professionals has enhanced strategic planning and definition of country-specific action plan priorities on organ donation and transplantation. Data of kidney transplantation provided in this report show a significant increase in transplantation activities in a 4-year period in Macedonia, Moldova, Bosnia and Hercegovina, Romania and Montenegro. The success of the donation and transplantation programmes was influenced by the engagement of key professionals and the establishment of organizational infrastructure with the implementation of an appropriate funding model. In conclusion, the DOI has provided an ethical framework for engagement of health professionals from south-eastern European countries. The newly established SEEHN RHDC as a technical coordinating body greatly contributed in building institutional capacity and strengthening regional collaboration between health authorities and professionals within

    2015-12-01

    Using biological proxies (pollen, spores, and charcoal), geochemical signals through X-ray fluorescence, and AMS 14C based chronology, we present a correlation between two new high resolution Little Ice Age (LIA) records from the Central Balkans that are part of one of the least studied regions of Europe. The sediments extracted from a western sinkhole and central Serbian oxbow lake are analyzed at 8-10-cm intervals to capture the nature and magnitude of the LIA at a resolution of 20 years. During the 15th-19th CE, indigenous tree (e.g. Quercus, Acer, Pinus) and herbaceous (e.g. Poaceae, Chenopodiaceae, Artemisia) pollen from these records demonstrate fluctuations in woodland-grassland dynamics. While tree populations from Central Serbia remain comparatively stable (40-60%), the trees of western Serbia vacillate drastically between 15% and 50%. Similarly, central Serbian grasses show variations of ~18-36% whereas the western Serbian grass populations exhibit abrupt oscillations between high (55%) and low (19%) percentages. As a proxy for surface erosion and clastic input into the lakes, the 1-cm resolution potassium and titanium counts are in strong agreement with varying herbaceous taxa. These variations in ecological signals across the cores can account for local factors including altitude, terrain exposure, soils etc., however, the dynamic human component of the landscape is evident through crop pollen (e.g. Cerealia, Juglans) and microscopic charcoal highlighting the dominant role of people in ecological changes. Although the two sites show certain differences in charcoal concentration, extremely high charcoal indicates accelerated land clearance between the 15th and 17th CE. Until the beginning of 18th CE, the cultivars (e.g. Secale, Triticum) occur with very low percentages and then peak to suggest improved agriculture in the region. In the post-LIA era, the 20th CE exhibits increased arboreal percentages and declining grasslands in both the two Central

    Full Text Available We studied autumn-winter food (November-February, 1997-2003 of the Stone Marten in the Balkan Mountains, Central Bulgaria. A total of 26 stomachs (18 of males and eight of females were examined, of which contents was expressed as the number of occurrence and relative frequency of occurrence. The result clearly showed that rodents are primary prey for the Stone Marten. Birds and insects were the following categories consumed. The edible dormouse was detected as a prey for the first time in Bulgaria. Besides, wild ungulates and domestic animals were occasionally scavenged, while neither fruits nor artificial materials were detected in the marten stomachs. Thus, our study showed that the Stone Marten in the Balkan Mountains tended to be more carnivorous in winter.

  6. Tendances et différences démographiques dans les Balkans

    Full Text Available The Balkans, which had long been characterized by higher fertility and earlier mortality than the more western and northern parts of the European continent, have become demographically modern. They are not for that reason any less diverse. This is witnessed, for example, by the gap that separates Bulgaria, which has long made the demographic transition, and Albania, the Former Yugoslav Republic of Macedonia, or Kosovo, where the natural population growth exceeds by far the migratory deficit. It is also witnessed by the very large spectrum of degrees of aging. Political and economic changes in the Balkans, the crises that accompanied them, the doubts that they have caused concerning the collective future, have reinforced the general tendencies toward delayed marriage and fertility, as well as toward reduced marriage and fertility rates. This has de facto consolidated the tendency toward demographic aging. Migrations, especially the migrations directly or indirectly related to the conflicts in former Yugoslavia, have also contributed to the modification of the demographic landscape and to the altering of the dynamic of the affected populations. They have also had an effect on the ethnic distribution of these populations. In the Balkans, whose bases have been strongly shaken in the past twenty years, heavy fertility and mortality tendencies limit the spectrum of possible mid-to-long term futures. There are also important consequences on the socioeconomic plan. All this in a political context, internal and external, that is the source of many questions.

    Los Balcanes, que se caracterizaron durante mucho tiempo por una fecundidad más elevada y una mortalidad más precoz que en las partes oeste y norte del continente europeo, están a partir de ahora inscritos en la modernidad demográfica. A pesar de ello son extremadamente diversos. Así lo confirma la distancia que separa, por ejemplo, Bulgaria, tierra de transición demográfica antigua

    2016-01-01

    Mesoamerican nephropathy (MeN), an epidemic in Central America, is a chronic kidney disease of unknown cause. In this article, we argue that MeN may be a uric acid disorder. Individuals at risk for developing the disease are primarily male workers exposed to heat stress and physical exertion that predisposes to recurrent water and volume depletion, often accompanied by urinary concentration and acidification. Uric acid is generated during heat stress, in part consequent to nucleotide release from muscles. We hypothesize that working in the sugarcane fields may result in cyclic uricosuria in which uric acid concentrations exceed solubility, leading to the formation of dihydrate urate crystals and local injury. Consistent with this hypothesis, we present pilot data documenting the common presence of urate crystals in the urine of sugarcane workers from El Salvador. High end-of-workday urinary uric acid concentrations were common in a pilot study, particularly if urine pH was corrected to 7. Hyperuricemia may induce glomerular hypertension, whereas the increased urinary uric acid may directly injure renal tubules. Thus, MeN may result from exercise and heat stress associated with dehydration-induced hyperuricemia and uricosuria. Increased hydration with water and salt, urinary alkalinization, reduction in sugary beverage intake, and inhibitors of uric acid synthesis should be tested for disease prevention.

  13. Clinical significance of neurocysticercosis in endemic villages

    International Nuclear Information System (INIS)

    Cerebral cysticercosis is the main cause of late-onset epilepsy in most developing countries. Data on the neuroepidemiology of cysticercosis in endemic populations is scarce. In an endemic village on the northern coast of Peru, 49 individuals with neurological symptomatology (41 epileptic and 8 non-epileptic) were screened for antibodies to Taenia solium, using a serum electroimmuno transfer blot assay. Fifteen subjects were seropositive, 14 (34%) of those with epilepsy but only one (13%) of those who were non-epileptic. A history of passing proglottides was associated with positive serology. Thirteen of the 15 seropositive individuals underwent cerebral computed tomography; only 7 (54%) were abnormal. A randomly selected sample of 20 pigs from the village was also tested, and 6 (30%) were seropositive. This study demonstrated the importance of cysticercosis in the aetiology of epilepsy in endemic villages and the close relationship between porcine and human infection

    The burden of disease due to chronic viral hepatitis constitutes a global threat. In many Balkan and Mediterranean countries, the disease burden due to viral hepatitis remains largely unrecognized, including in high-risk groups and migrants, because of a lack of reliable epidemiological data, suggesting the need for better and targeted surveillance for public health gains. In many countries, the burden of chronic liver disease due to hepatitis B and C is increasing due to ageing of unvaccinated populations and migration, and a probable increase in drug injecting. Targeted vaccination strategies for hepatitis B virus (HBV) among risk groups and harm reduction interventions at adequate scale and coverage for injecting drug users are needed. Transmission of HBV and hepatitis C virus (HCV) in healthcare settings and a higher prevalence of HBV and HCV among recipients of blood and blood products in the Balkan and North African countries highlight the need to implement and monitor universal precautions in these settings and use voluntary, nonremunerated, repeat donors. Progress in drug discovery has improved outcomes of treatment for both HBV and HCV, although access is limited by the high costs of these drugs and resources available for health care. Egypt, with the highest burden of hepatitis C in the world, provides treatment through its National Control Strategy. Addressing the burden of viral hepatitis in the Balkan and Mediterranean regions will require national commitments in the form of strategic plans, financial and human resources, normative guidance and technical support from regional agencies and research.

    The Balkan Peninsula is a complex cultural mosaic comprising populations speaking languages from several branches of the Indo-European family and Altaic, as well as culturally-defined minorities such as the Aromuns who speak a Romance language. The current cultural and linguistic landscape is a palimpsest in which different peoples have contributed their cultures in a historical succession. We have sought to find any evidence of genetic stratification related to those cultural layers by typing both mtDNA and Y chromosomes, in Albanians, Romanians, Macedonians, Greeks, and five Aromun populations. We have paid special attention to the Aromuns, and sought to test genetically various hypotheses on their origins. MtDNA and Y-chromosome haplogroup frequencies in the Balkans were found to be similar to those elsewhere in Europe. MtDNA sequences and Y-chromosome STR haplotypes revealed decreased variation in some Aromun populations. Variation within Aromun populations was the primary source of genetic differentiation. Y-chromosome haplotypes tended to be shared across Aromuns, but not across non-Aromun populations. These results point to a possible common origin of the Aromuns, with drift acting to differentiate the separate Aromun communities. The homogeneity of Balkan populations prevented testing for the origin of the Aromuns, although a significant Roman contribution can be ruled out.

  17. Evaluation of reflux nephropathy, pyelonephritis and renal dysplasia

    International Nuclear Information System (INIS)

    MR urography has the potential to significantly improve our understanding of the relationship between reflux nephropathy, pyelonephritis, vesicoureteric reflux and renal dysplasia. MR urography utilizes multiple parameters to assess both renal anatomy and function and provides a more complete characterization of acquired and congenital disease. Pyelonephritis and renal scarring can be distinguished by assessing the parenchymal contours and signal intensity. Characteristic imaging features of renal dysplasia include small size, subcortical cysts, disorganized architecture, decreased and patchy contrast enhancement as well as a dysmorphic pelvicalyceal system. Because of its ability to subdivide and categorize this heterogeneous group of disorders, it seems inevitable that MR urography will replace DMSA renal scintigraphy as the gold standard for assessment of pyelonephritis and renal scarring. MR urography will contribute to our understanding of renal dysplasia and its relationship to reflux nephropathy. (orig.)

    Full Text Available Although diabetes mellitus, a metabolic disease, does not fall into the group of diseases induced by toxic substances or environmental pollution, there is much evidence that some chemicals have considerable importance in its development. Exposure to substances with potential renal toxicity is especially dangerous for diabetics because it accelerates and intensifies diabetic nephropathy. This paper discusses the relationship between the xenobiotics and the development of diabetes mellitus and diabetic nephropathy with particular emphasis on those substances that causes the greatest damage to the kidneys. These are cadmium, iron, lead, arsenic, polychlorinated organic compounds, nitrogen compounds, and contrast agents. In addition, the mechanisms of diabetes mellitus induction or kidney damage by these xenobiotics are described.

  5. Oxidative Stress in Diabetic Nephropathy with Early Chronic Kidney Disease

    Science.gov (United States)

    Andrade-Sierra, Jorge

    2016-01-01

    The increase in the prevalence of diabetes mellitus (DM) and the secondary kidney damage produces diabetic nephropathy (DN). Early nephropathy is defined as the presence of microalbuminuria (30–300 mg/day), including normal glomerular filtration rate (GFR) or a mildly decreased GFR (60–89 mL/min/1.73 m2), with or without overt nephropathy. The earliest change caused by DN is hyperfiltration with proteinuria. The acceptable excretion rate of albumin in urine is 300 mg/day. Chronic kidney disease (CKD) is characterized by abnormalities in renal function that persist for >3 months with health implications. Alterations in the redox state in DN are caused by the persistent state of hyperglycemia and the increase in advanced glycation end products (AGEs) with ability to affect the renin-angiotensin system and the transforming growth factor-beta (TGF-β), producing chronic inflammation and glomerular and tubular hypertrophy and favoring the appearance of oxidative stress. In DN imbalance between prooxidant/antioxidant processes exists with an increase in reactive oxygen species (ROS). The overproduction of ROS diminishes expression of the antioxidant enzymes (manganese superoxide dismutase, glutathione peroxidase, and catalase). The early detection of CKD secondary to DN and the timely identification of patients would permit decreasing its impact on health. PMID:27525285

    2011-01-01

    Full Text Available We describe here a rare case of variant of mycosis fungoides (MF: ichthyosiform MF with alopecia and atypical membranous nephropathy. The diagnosis was made based on the following findings: generalized ichthyosis-like eruption, alopecia, enlarged superficial lymph nodes, proteinuria, and hematuria, the histological features of the skin biopsy from both ichthyotic and alopecic lesions with immunohistochemical staining, and the renal biopsy examination with immunofluorescence. The histological examination of ichthyotic and alopecic lesions displayed a predominant infiltration of atypical lymphocytes in the upper dermis with the characteristics of epidermotropism and folliculotropism. Immunohistochemical studies demonstrated that most infiltrated atypical lymphocytes were CD3, CD4, and CD45RO positive, whereas negative for CD5, CD7, CD20, CD30, and CD56. A renal biopsy examination revealed atypical membranous nephropathy with deposition of immunoglobulin G (IgG, IgM, IgA, C1q, and C3. In this case atypical membranous nephropathy was involved, which is very uncommon and has never been presented in the literature to date. Although ichthyosiform MF usually features a relatively favorable course, diffuse alopecia and the renal involvement in this case might indicate aggressive disease and poor prognosis.

    Full Text Available Glomerular involvement occurs as a rare form of renal manifestation in Plasmodium falciparum malaria. Here, we report a rare case of falciparum malaria-associated IgA nephropathy. A 28-year-old man was admitted because of fever and abdominal pain. Ultrasound and computed tomography (CT showed right kidney pyonenphrosis. Despite placing a nephrostomy tube, fever continued. Repeated CT was in favor of focal pyelonephritis. In addition, peripheral blood smear suggested malaria. Anti-malarial drugs were initiated and right nephrectomy was performed. One year after recovery from malaria, a persistent rise in serum creatinine was detected. A left kidney biopsy showed mesangial proliferation and dominant IgA deposits in immunofluorescence study while C1q was not deposited. The impression was IgA nephropathy with M1E0S0T0 of Oxford classification. The patient was prescribed a combination of low dose prednisolone and angiotensin converting enzyme inhibitor. Six months after treatment serum creatinine decreased from 1.6 mg/dL to 1.3mg/dL and urine abnormalities were disappeared. Our findings suggest that malaria infection might be associated with IgA nephropathy.

    Full Text Available The study is devoted to the identification of structural markers of ischemic nephropathy by studying facies (dry drops of urine in newborn infants. The study involved two groups of full-term newborns with gestational age 38-41 weeks and signs of ischemic nephropathy: 1st - 75 children who suffered severe asphyxia, 2nd - 75 children with moderate asphyxia. Comparison group consisted of 20 infants without asphyxia at birth. Morphological changes were detected in dry drops by microscopy at 40-fold increase in 1-2 and 7-8 days of life. Asphyxia cause disturbance of renal filtration, tubular reabsorption and secretion that lead to increase levels of organic components and mineral salts in urine, crystallization of which forms a specific picture of facies. By urine’s facies morphology at 1-2 days of life is possible to evaluate renal function in newborns suffered from asphyxia. The number of inclusions in facies, their total area and distribution are depending on the severity of asphyxia. Structural changes in the urine of children with ischemic nephropathy remain till the end of the early neonatal period.

    Spontaneous remission is a well known characteristic of idiopathic membranous nephropathy, but contemporary studies describing predictors of remission and long-term outcomes are lacking. We conducted a retrospective, multicenter cohort study of 328 patients with nephrotic syndrome resulting from idiopathic membranous nephropathy that initially received conservative therapy. Spontaneous remission occurred in 104 (32%) patients: proteinuria progressively declined after diagnosis until remission of disease at 14.7 ± 11.4 months. Although spontaneous remission was more frequent with lower levels of baseline proteinuria, it also frequently occurred in patients with massive proteinuria: 26% among those with baseline proteinuria 8 to 12 g/24 h and 22% among those with proteinuria >12 g/24 h. Baseline serum creatinine and proteinuria, treatment with angiotensin-converting enzyme inhibitors or angiotensin receptor antagonists, and a >50% decline of proteinuria from baseline during the first year of follow-up were significant independent predictors for spontaneous remission. Only six patients (5.7%) experienced a relapse of nephrotic syndrome. The incidence of death and ESRD were significantly lower among patients with spontaneous remission. In conclusion, spontaneous remission is common among patients with nephrotic syndrome resulting from membranous nephropathy and carries a favorable long-term outcome with a low incidence of relapse. A decrease in proteinuria >50% from baseline during the first year predicts spontaneous remission. PMID:20110379

    Full Text Available Balkan Turkish dialects are the dialects established in varioushistorical, geographical, social and cultural conditions by the Turks,who had been moved from Anatolian and settled in the Balkans fromthe mid 14th century.Balkan Turkish dialects, just like Anatolian dialects, have hadnumber of branches due to the fact that they belonged to differentTurkish tribes and lived within various political, social, cultural andgeographical conditions on the one hand and interacted with differentlanguages and cultures, mainly like Slavic ones, on the other.The ultimate objective of the researches on dialects, which havegained great significance nowadays, is to classify the existing dialects ina certain geography of language upon certain criteria within themselvesand even within the sub-dialects and eventually to form the atlases ofthe dialects. While the Western countries and some Turkish states havetaken great steps in this field, unfortunately it is hard to say the samefor the dialects of Turkey Turkish yet. Although the classificationproblem of the dialects of Turkey Turkish has widely been solved afterquite a long process, it is yet not possible to argue the same for BalkanTurkish dialects. The researches on Balkan Turkish dialects startedwith compilations of I. Kunos and the researches of T. Kowalski andthere have been some classification attempts later by mainly J. Németh,D. Gacanov, G. Hazai, M. Mollava and I. Dryga. However it is too earlyto claim that the last word has been spoken out on this matter yet.There are still a lot to do with Balkan Turkish dialects which are lessresearchescompared to Anatolian dialects.In this paper the researches on Balkan Turkish dialects up thepresent day is going to be introduced, the basic criteria and thecommon and differing criteria used by the researchers who made theclassification is going to be assessed and finally it is going to bediscussed whether some other criteria can be used for the mainstreamdialect

    Objectives: Immunoglobulin A nephropathy is the most common cause of chronic renal failure among primary glomerulonephritis patients. The ability to diagnose immunoglobulin A nephropathy remains poor. However, renal biopsy is an inconvenient, invasive, and painful examination, and no reliable biomarkers have been developed for use in routine patient evaluations. The aims of the present study were to identify immunoglobulin A nephropathy patients, to identify useful biomarkers of immunoglobulin A nephropathy and to establish a human immunoglobulin A nephropathy metabolic profile. Methods: Serum samples were collected from immunoglobulin A nephropathy patients who were not using immunosuppressants. A pilot study was undertaken to determine disease-specific metabolite biomarker profiles in three groups: healthy controls (N = 23), low-risk patients in whom immunoglobulin A nephropathy was confirmed as grades I-II by renal biopsy (N = 23), and high-risk patients with nephropathies of grades IV-V (N = 12). Serum samples were analyzed using proton nuclear magnetic resonance spectroscopy and by applying multivariate pattern recognition analysis for disease classification. Results: Compared with the healthy controls, both the low-risk and high-risk patients had higher levels of phenylalanine, myo-inositol, lactate, L6 lipids ( CH-CH{sub 2}-CH = O), L5 lipids (-CH{sub 2}-C = O), and L3 lipids (-CH{sub 2}-CH{sub 2}-C = O) as well as lower levels of {beta}-glucose, {alpha}-glucose, valine, tyrosine, phosphocholine, lysine, isoleucine, glycerolphosphocholine, glycine, glutamine, glutamate, alanine, acetate, 3-hydroxybutyrate, and 1-methylhistidine. Conclusions: These metabolites investigated in this study may serve as potential biomarkers of immunoglobulin A nephropathy. Point scoring of pattern recognition analysis was able to distinguish immunoglobulin A nephropathy patients from healthy controls. However, there were no obvious differences between the low-risk and high

    Contrast-induced nephropathy (CIN) is a well-known complication of therapeutic and diagnostic procedures requiring contrast administration and accounts for 10% of acute renal failure in hospitalized patients. Although the incidence of this complication is relatively low, its consequences can be catastrophic. The development of CIN is associated with increased length of hospital stay, an increased requirement for acute dialysis, and an increased risk of death. Preexisting renal dysfunction, age, diabetes, congestive heart failure, and volume of administered contrast are all associated with a risk of developing CIN. Despite a large number of clinical trials that have evaluated prophylaxis strategies for CIN, no uniform strategies have been developed so far. The use of N-acetyl-L-cysteine (NAC) or theophylline in specific subgroups of patients has been shown to reduce dialysis requirement and mortality in patients undergoing angiographic procedures. Hemofiltration has also shown positive results. In this review we will discuss the epidemiology and the risk factors for CIN and the evidence for commonly employed prophylaxis strategies, and we will provide general recommendations with respect to CIN prevention and management. A practicable strategy to prevent CIN includes: correct identification of individuals at greatest risk, thorough evaluation of whether other diagnostic maneuvers could be employed instead (i.e., sonography), application of low-osmolar contrast media at the minimum acceptable dose, stopping potential nephrotoxic drugs (NSAID), hydration with sodium chloride 0.9% 1 ml/kg per h i.v. 12 h before and after CM application, administration of acetylcysteine 600 mg twice the day before and after (in cases of emergency investigation and high-risk patients 1200 mg i.v.), and theophylline (250-350 mg) the day before and the day after CM application (in cases of emergency investigation 5 mg/kg i.v.).

    Dirofilaria repens causes an emerging zoonotic disease in Europe, particularly in its southern part, the Mediterranean region. Many reports on human dirofilariosis have been published recently, but little is known about the wildlife hosts and reservoirs of this parasite in nature. This paper presents the first records of adult D. repens specimens from free-ranging carnivores in Central Balkan countries (Serbia and Macedonia). During the period 2009-2013, a total of 145 regularly shot canids were examined for the presence of D. repens adults. In order to investigate their role as hosts and potential wild reservoirs of this zoonosis, 71 wolves (Canis lupus), 48 foxes (Vulpes vulpes) and 26 jackals (Canis aureus) were examined. Under the skin of two wolves (one from Serbia and one from Macedonia) and of a red fox from Serbia D. repens adults were found. In all three cases only one parasite was present. Further research on wild canids is needed, particularly on species widening their range (such as jackals) and those living near human settlements (foxes and jackals), which facilitates the transmission of the parasites to dogs and humans.

    Full Text Available The aim of this paper was to analyze the degree of change in price and co- movement of prices between markets. The distinctiveness of the study is that it introduced a single product (highly perishable product price relationship analysis between a pair of spatially separated markets in the countries of the Western Balkan. This study attempts to comprehend to what extent the Macedonian domestic market is integrated into the regional markets, as well as to understand the relationship between the spatially separated regional markets. The data refer to the domestic Macedonian market and four different regional markets (Croatia, Serbia, Kosovo and Montenegro, as major importers of Macedonian fresh tomatoes. These countries were part of a common market until the 1990s and in the past period transited to a market economy. The method used is common time series analysis through unit root test, co-integration test and causality test. The study showed that the Macedonian economy, especially in terms of the tomato industry, is highly vulnerable and dependant on external markets. Future developments do not only depend upon the advances in the country, but also on developments in the export destinations. This also applies to the other concerned countries in the regions. The main finding is that a small country such as Macedonia is absorbed by developments in other countries in the region. This finding is supported by the results of the study that demonstrated a high level of co-integration between the domestic and regional markets.

  20. Economic development in the European super-periphery: Evidence from the Western Balkans

    Directory of Open Access Journals (Sweden)

    Bartlett Will

    2009-01-01

    Full Text Available This paper argues that the conflicts that afflicted the Western Balkan region in the 1990s pushed the countries into the European 'super-periphery', characterized by deindustrialization and high unemployment, ethnic and regional fragmentation, political turmoil, and instability. Integration into international trade has been disrupted, leading to chronic balance of payments deficits. Low inflows of international capital, due to high country risk, have hindered technological catch-up and weakened international competitiveness. An unattractive environment for productive entrepreneurship has created barriers to the entry of SMEs, and at the same time large informal economies. Several countries have become labour-export economies, with significant outflows of skilled labour. Economic development follows a low-skill growth path. The current global economic crisis is having a further deleterious effect as export revenues, foreign direct investment, and labour remittances all diminish. Furthermore, as transition has proceeded, disparities between capital cities and rural areas have increased, while weak administrative capacities have hindered the implementation of effective local development policies to counteract these effects. Endogenous local development cannot provide an alternative to greater engagement with the global economy. The conclusion is that the countries of the region have been left out of the most beneficial elements of the globalisation process, while simultaneously suffering from its main defects. Without a faster process of accession to the EU, local disparities are likely to widen, and the region may remain within the European super-periphery for the foreseeable future.

    2010-01-01

    Full Text Available The paper provides analysis of foreign direct investment (FDI dynamics and its determinants for the group of countries lately referred to as Western Balkans (non- EU ex-Yugoslavia countries plus Albania. Due to vulnerable external positions and enhanced funding requirements related to the EU accession and catching-up, FDI is often highly welcomed by government officials in the South East European (SEE countries. The notion that FDI is frequently accompanied by knowledge and know-how transfer makes this source of capital growth even more desirable than simple capital accumulation from frequently inadequate domestic savings. The analysis of the FDI determinants on the overall economy level conducted within the panel data framework aims to provide the answer whether the same factors as in Central and Eastern European countries, now new EU member states, are relevant for the sampled countries. Due to data limitations and the frequent emergence of new countries in the region, the analysis does not extend to the early transition period. Since it entails the beginning of the financial crisis, the comparison of the results obtained with those of previous studies will enable the discussion of internal versus external factors of FDI attraction in the region.

    In this study, we aimed to assess the population status of bleak (Alburnus spp.) over the Western Balkan Peninsula in terms of its sustainable use. A second objective was to determine key factors important for fishery management planning. Two different basins, continental (the Danube Basin and the Sava River sub-basin) and marine (the Adriatic and the Aegean Sea Basins) were examined. A sustainability assessment and factor analysis were conducted using the adjusted ESHIPPOfishing model, extended with additional socio-economic sub-elements, and the categorical principal components analysis (CATPCA), respectively. The results of the assessment revealed the bleak populations in the Danube Basin and the Sava River sub-basin to be highly sustainable. The population characteristics with abiotic and biotic factors were responsible for this status, while the influence of socio-economic factors was insignificant. The sustainability status of the bleak populations of the Mediterranean basin varied, with the populations from Ohrid and Skadar Lakes showing a high and those from Prespa and Dojran Lakes a medium status. Socio-economic factors with traditional fishing were the most important for the Mediterranean bleak populations. PMID:26216478

    Lakes Prespa and Ohrid on the Balkans are considered to be amongst the oldest lakes in Europe. Both lakes are hydraulically connected via karst aquifers. From Lake Ohrid, several up to ca. 15 m long sediment records were studied during the past years. In this study, a first long sediment record from Lake Prespa was studied in order to shed more light on the influence of Lake Prespa on Lake Ohrid and the environmental history of the region. Radiocarbon dating and the occurrence of 3 dated tephra layers provide a good age control and indicate that the 10.5 m long sediment record reaches back to 48 ka. The comparison of the results from this study with those from former studies of the Lake Ohrid cores indicates that Lake Prespa is more susceptible to environmental changes due to its lower volume and water depth. Glacial sedimentation is characterized by low organic matter contents and absence of carbonates in the sediments, which indicate oligotrophic conditions in both lakes. Holocene sedimentation is characterized by particularly high carbonate contents in Lake Ohrid and by particularly high organic matter contents in Lake Prespa, which indicate a shift towards more mesotrophic conditions in the latter. Long-term environmental changes and short-term events, such as the Heinrich events during the Pleistocene or the 8.2 cooling event during the Holocene, are well recorded in both lakes, but partly expressed in different proxies.

    2014-12-01

    Full Text Available Following the assumption that the Neolithic witnessed the first widespread appearance of permanent houses and households, in line with the adoption of sedentism, this article examines the relevance of residential and construction practices to our understanding of the process of Neolithic expansion from Anatolia to the Balkans. Three practices, with a broad spatial distribution, are reviewed: house burning, the vertical superimposition of houses and intra-settlement burial. The article first outlines the basis of a contextual method to retrieve practices from material patterning left in the record, such as burnt houses for the practice of intentional house burning. The next section delves into the similarities in practices between Neolithic communities in Anatolia, Thrace and Greece, during the 7th and 6th millennia BC cal. to suggest that: 1 house burning was a key strategy to bring houses to ‘closure’ at the end of their use-lives; 2 people took advantage of the stability of extant houses to build new houses atop; and 3 this practice was closely connected with the burial of the dead in, or in close proximity to, houses. Common attitudes to residence and construction across a vast array of sites underpin similarities in house form and house use patterns. To conclude, the discussion highlights the need for a dynamic approach, based on comparative time-lines of practices, to determine the direction of spread.

    Full Text Available This paper employs the factor analysis technique and data from the UNDP/UNICEF Social Inclusion Survey to construct a material deprivation index for fi ve transitional societies in the Balkans (FYR Macedonia and Serbia, Eastern Europe (Moldova and Ukraine and Central Asia (Kazakhstan. The distribution of deprivation between these societies can be largely explained by their level of economic development, but within-county variance is not limited to monetary dimension. Controlling for settlement type, human capital and employment status in multivariate settings, the paper tests the hypothesis of the continuous importance of occupational social class and the emerging role of diff erent life phases in individuals’ welfare outcomes. The results reveal that all specifi ed social classes and most of the defi ned life phases have diverse and statistically signifi cant eff ects on the constructed deprivation index and the likelihood of being under 70 per cent of the median deprivation threshold. Belonging to non-skilled manual, farmers and skilled manual social class as well as being a child or lone parent were revealed to have the highest risk of material deprivation. These fi ndings are in line with the conclusions made for the Western welfare democracies on the complementary nature of social class and life course dimensions in explaining social hardship.

    Full Text Available In early stages SMEs were seen as insignificant supplement to large business supply, whereas today they have a very important social and economic role, because of their contribution to job creation. These contributions are very valuable in times of crises and rising unemployment. In Kosovo and the Western Balkan countries, including countries such as Albania, Macedonia, Montenegro, Serbia and Bosnia and Herzegovina, the development of SMEs can contribute in facing many challenges, effects of inequality, high level of unemployment and demographic challenges. In addition, SME development can contribute to strengthening the competitiveness and productivity, while also promoting the growth of income per capita. Besides the positive perception the creation of small and medium enterprises has, it is also indispensable to consider their extinction rate, being the most affected category of businesses, especially in the initial stages. It is proved that the net SME creation and cross-country differences in the relationship between new businesses and extinct businesses, can serve as a recommendation for policy makers in order to create a favorable climate for small and medium enterprises. GCI indicators that measures global competitiveness are used to determine if the climate of competitiveness predicts the development of SMEs.

    Full Text Available Coming from standard economic growth theory and empirical evidences, we concentrated on the convergence process as a result of structural changes in economy. We investigate the differences among countries in EU in terms of the share in total economy of main sectors. Then, based on the spatial (empirical distribution of such shares in EU we are proposing a model to estimate a typology of the convergence process in the European area. Taking into account the existing differences among sectors in matter of productivity, there are two versions of the model: considering the share of sectors in total employment and the share of sectors in GDP, respectively. Moreover, we developed several modelling schemes that could be useful to improve the strategies oriented to achieve a real convergence in EU and further in the Adriatic-Balkans Region. In this way, we can obtain simulations from a country or group of countries (European Union, for example on long term and quantifying the impact of structural changes on the convergence process. Indeed, the actual global crisis seems to influence negatively the convergence process in the EU. As a rule, just newly adhered countries have been more affected by the actual crisis. Today all forecasts are suffering from uncertainty. Thus, further efforts must be allocated to evaluate the negative impact of actual crisis on the convergence process.

    Full Text Available This work focuses on the heavy metals contents of the size-segregated urban aerosol of the continental area of Balkans. The distribution of nano/micron heavy metals in the size-segregated urban aerosol of Belgrade center was studied during the summer–autumn of 2008. The particle size distribution in the size ranges Dp ≤ 0.49 μm, 0.49 ≤ Dp ≤ 0.95 μm, 0.95 ≤ Dp ≤ 1.5 μm, 1.5 ≤ Dp ≤ 3.0 μm, 3.0 ≤ Dp ≤ 7.2 μm and Dp ≥ 7.2 μm was measured. The aerosol samples were submitted to gravimetric and chemical analyses. The obtained mean mass concentration of the PM fractions was in accordance with an urban aerosol distribution. The aerosol mass concentrations were determined by gravimetric measurements (mGM and, for heavy metals analyzed by ICP/MS.

    Extensive die-back and mortality of various ornamental trees and shrubs has been observed in parts of the Western Balkans region during the past decade. The disease symptoms have been typical of those caused by pathogens residing in the Botryosphaeriaceae. The aims of this study were to isolate and characterize Botryosphaeriaceae species associated with diseased ornamental trees in Serbia, Montenegro, Bosnia and Herzegovina. Isolates were initially characterized based on the DNA sequence data for the internal transcribed spacer rDNA and six major clades were identified. Representative isolates from each clade were further characterized using DNA sequence data for the translation elongation factor 1-alpha, β-tubulin-2 and large subunit rRNA gene regions, as well as the morphology of the asexual morphs. Ten species of the Botryosphaeriaceae were identified of which eight, i.e., Dothiorella sarmentorum, Neofusicoccum parvum, Botryosphaeria dothidea, Phaeobotryon cupressi, Sphaeropsis visci, Diplodia seriata, D. sapinea and D. mutila were known taxa. The remaining two species could be identified only as Dothiorella spp. Dichomera syn-asexual morphs of D. sapinea, Dothiorella sp. 2 and B. dothidea, as well as unique morphological characters for a number of the known species are described. Based on host plants and geographic distribution, the majority of Botryosphaeriaceae species found represent new records. The results of this study contribute to our knowledge of the distribution, host associations and impacts of these fungi on trees in urban environments.

    This work presents characteristics of atmospheric aerosols of urban central Balkans area, using a size-segregated aerosol sampling method, calculation of mass distributions, SEM/EDX characterization, and ICP/MS analysis. Three types of mass distributions were observed: distribution with a pronounced domination of coarse mode, bimodal distribution, and distribution with minimum at 1 μm describing the urban aerosol. SEM/EDX analyses have shown morphological difference and variation in the content of elements in samples. EDX spectra demonstrate that particles generally contain the following elements: Al, Ca, K, Fe, Mg, Ni, K, Si, S. Additionally, the presence of As, Br, Sn, and Zn found in air masses from southeast segment points out the anthropogenic activities most probably from mining activities in southeastern part of Serbia. The ratio Al/Si equivalent to the ratio of desert dust was associated with air masses coming from southeastern and southwestern segments, pointing to influences from North Africa and Middle East desert areas whereas the Al/Si ratio in other samples is significantly lower. In several samples, we found high values of aluminum in the nucleation mode. Samples with low share of crustal elements in the coarse mode are collected when Mediterranean air masses prevailed, while high share in the coarse mode was associated with continental air masses that could be one of the approaches for identification of the aerosol origin.

  19. Distribution of Mycobacterium ulcerans in buruli ulcer endemic and non-endemic aquatic sites in Ghana.

    Directory of Open Access Journals (Sweden)

    Heather R Williamson

    Full Text Available Mycobacterium ulcerans, the causative agent of Buruli ulcer, is an emerging environmental bacterium in Australia and West Africa. The primary risk factor associated with Buruli ulcer is proximity to slow moving water. Environmental constraints for disease are shown by the absence of infection in arid regions of infected countries. A particularly mysterious aspect of Buruli ulcer is the fact that endemic and non-endemic villages may be only a few kilometers apart within the same watershed. Recent studies suggest that aquatic invertebrate species may serve as reservoirs for M. ulcerans, although transmission pathways remain unknown. Systematic studies of the distribution of M. ulcerans in the environment using standard ecological methods have not been reported. Here we present results from the first study based on random sampling of endemic and non-endemic sites. In this study PCR-based methods, along with biofilm collections, have been used to map the presence of M. ulcerans within 26 aquatic sites in Ghana. Results suggest that M. ulcerans is present in both endemic and non-endemic sites and that variable number tandem repeat (VNTR profiling can be used to follow chains of transmission from the environment to humans. Our results suggesting that the distribution of M. ulcerans is far broader than the distribution of human disease is characteristic of environmental pathogens. These findings imply that focal demography, along with patterns of human water contact, may play a major role in transmission of Buruli ulcer.

    Full Text Available Aims and Objectives. Metabolic dysregulation has failed to explain clinical variability of patients with diabetic nephropathy and hence a renewed interest emerged in haemodynamic factors as determinant of progression and development of diabetic nephropathy. We therefore studied for various factors which can correlate with raised renal vascular resistance in diabetic nephropathy. Material and Methods. Renal vascular resistance was measured in patients with established and incipient diabetic nephropathy and compared with controls using noninvasive color Doppler examinations of intrarenal vasculature. Results. Renal vascular resistance correlated with age, duration of disease, GFR, serum creatinine, and stage of retinopathy. Renal vascular resistance was significantly reduced in patients on treatment with RAAS inhibitors and insulin, than those on OHA and antihypertensives other than RAAS inhibitors. Conclusion. The study implies that renal vascular resistance may help identify diabetics at high risk of developing nephropathy, and these set of patients could be candidates for RAAS inhibition and early insulin therapy even in patients without albuminuria.

    Full Text Available We describe herein 2 patients who developed Vogt-Koyanagi-Harada syndrome in the course of renal biopsy-proven immunoglobulin A (IgA nephropathy. A 61-year-old man with an 11-year history of IgA nephropathy and a 16-year history of thyroiditis, and a 56-year-old man with a 5-year history of IgA nephropathy developed Vogt-Koyanagi-Harada syndrome. At the time of the eye disease presentation, IgA nephropathy was stable without corticosteroids in both patients. Vogt-Koyanagi-Harada syndrome was successfully treated with intravenous administration of prednisolone tapered from 200 mg daily. Vogt-Koyanagi-Harada syndrome is associated with IgA nephropathy, suggesting a similar autoimmune mechanism for both diseases.

    The most problematic issue in clinical nephrology worldwide is the relentless and progressive increase in patients with end-stage renal disease (ESRD). Diabetic nephropathy has considerable impact on society in the areas of public health and social economy; many scientists are involved in research for the elucidation of the pathogenesis of diabetic nephropathy and for the prevention and cure of the disease. In contrast, diabetic nephropathy was a neglected or ignored disease in the historical era, and few dedicated physicians recognized the disease process of diabetic nephropathy. In this review, we look back on the history of basic and clinical research on diabetic nephropathy and survey the recent progress of the research, especially focusing on the contribution of Japanese scientists.

    2006-12-01

    Full Text Available Species richness, endemism and areas that are rich in both species and endemic species were assessed and mapped for Namibia. High species diversity corresponds with zones where species overlap. These are particularly obvious where there are altitudinal variations and in high-lying areas. The endemic flora of Namibia is rich and diverse. An estimated 16% of the total plant species in Namibia are endemic to the country. Endemics are in a wide variety of families and sixteen genera are endemic. Factors that increase the likelihood of endemism are mountains, hot deserts, diversity of substrates and microclimates. The distribution of plants endemic to Namibia was arranged in three different ways. Firstly, based on a grid count with the phytogeographic value o f the species being equal, overall endemism was mapped. Secondly, range restricted plant species were mapped individually and those with congruent distribution patterns were combined. Thirdly, localities that are important for very range-restricted species were identified. The resulting maps o f endemism and diversity were compared and found to correspond in many localities. When overall endemism is compared with overall diversity, rich localities may consist of endemic species with wide ranges. The other methods identify important localities with their own distinctive complement of species.

    We compiled and identified a list of Chinese. endemic seed plant species based on a large number of published References and expert reviews. The characters of these seed plant species and their distribution patterns were described at length. China is rich in endemic seed plants, with a total of 14 939 species (accounting for 52.1%of its total seed plant species) belonging to 1584 genera and 191 families. Temperate families and genera have a significantly higher proportion of endemism than cosmopolitan and tropical ones. The most primitive and derived groups have significantly higher endemism than the other groups. The endemism of tree, shrub, and liana or vine is higher than that of total species; in contrast, the endemism of herb is lower than that of total species. Geographically,these Chinese endemic plants are mainly distributed in Yunnan and Sichuan provinces, southwest China. Species richness and proportion of these endemic plants decrease with increased latitude and have a unimodal response to altitude. The peak value of proportion of endemism is at higher altitudes than that of total species and endemic species richness. The proportions of endemic shrub, liana or vine, and herb increase with altitude and have a clear unimodal curve. In contrast, the proportion of tree increases with altitude, with a sudden increase at~4000 m and has a completely different model. To date, our study provides the most comprehensive list of Chinese endemic seed plant species and their basic composition and distribution features.

    Nine new microsatellite markers (SSR) were isolated from Salvia officinalis L. A total of 125 alleles, with 8 to 21 alleles per locus, were detected in a natural population from the east Adriatic coast. The observed heterozygosity, expected heterozygosity, and polymorphic information content ranged from 0.46 to 0.83, 0.73 to 0.93 and 0.70 to 0.92, respectively. New microsatellite markers, as well as previously published markers, were tested for cross-amplification in Salvia brachyodon Vandas, a narrow endemic species known to be present in only two localities on the Balkan Peninsula. Out of 30 microsatellite markers tested on the natural S. brachyodon population, 15 were successfully amplified. To obtain evidence of recent bottleneck events in the populations of both species, observed genetic diversity (H(E)) was compared to the expected genetic diversity at mutation-drift equilibrium (H(EQ)) and calculated from the observed number of alleles using a two-phased mutation model (TPM). Recent bottleneck events were detected only in the S. brachyodon population. This result suggests the need to reconsider the current threat category of this endemic species.

  8. Alterations of urinary metabolite profile in model diabetic nephropathy

    International Nuclear Information System (INIS)

    Highlights: • 1H NMR spectroscopy was employed to study urinary metabolite profile in diabetic mouse models. • Mouse urinary metabolome showed major changes that are also found in human diabetic nephropathy. • These models can be new tools to study urinary biomarkers that are relevant to human disease. - Abstract: Countering the diabetes pandemic and consequent complications, such as nephropathy, will require better understanding of disease mechanisms and development of new diagnostic methods. Animal models can be versatile tools in studies of diabetic renal disease when model pathology is relevant to human diabetic nephropathy (DN). Diabetic models using endothelial nitric oxide synthase (eNOS) knock-out mice develop major renal lesions characteristic of human disease. However, it is unknown whether they can also reproduce changes in urinary metabolites found in human DN. We employed Type 1 and Type 2 diabetic mouse models of DN, i.e. STZ-eNOS−/− C57BLKS and eNOS−/− C57BLKS db/db, with the goal of determining changes in urinary metabolite profile using proton nuclear magnetic resonance (NMR). Six urinary metabolites with significantly lower levels in diabetic compared to control mice have been identified. Specifically, major changes were found in metabolites from tricarboxylic acid (TCA) cycle and aromatic amino acid catabolism including 3-indoxyl sulfate, cis-aconitate, 2-oxoisocaproate, N-phenyl-acetylglycine, 4-hydroxyphenyl acetate, and hippurate. Levels of 4-hydroxyphenyl acetic acid and hippuric acid showed the strongest reverse correlation to albumin-to-creatinine ratio (ACR), which is an indicator of renal damage. Importantly, similar changes in urinary hydroxyphenyl acetate and hippurate were previously reported in human renal disease. We demonstrated that STZ-eNOS−/− C57BLKS and eNOS−/− C57BLKS db/db mouse models can recapitulate changes in urinary metabolome found in human DN and therefore can be useful new tools in metabolomic

  9. Effect of pregnancy on diabetic nephropathy and retinopathy

    International Nuclear Information System (INIS)

    Objective: To determine whether pregnancy worsens renal function in women with diabetic nephropathy and the effect of pregnancy on diabetic retinopathy. Subject and Methods: Thirty-five patients (aged 20-36 years) identified with diabetic nephropathy and moderate to severe renal dysfunction (creatinine Cr) - > 1.4 mg/dl) at pregnancy onset by retrospective chart review. Alterations in glomerular filtration rate (GFR) were estimated. An equal number of non-pregnant premenopausal type I diabetic women with similar degrees of renal dysfunction served as controls for non-pregnant rate of decline of renal function and potential contributing factors. Student's t-test and repeated measures analysis of variance were analyzed. Results: Mean serum Cr rose from 1.8 mg/dl pre pregnancy to 2.5 mg/dl in the third trimester. Renal function was stable in 27%, showed transient worsening in pregnancy in 27%, and demonstrated a permanent decline in 45%. Proteinuria increased in pregnancy in 79%. Exacerbation of hypertension or pre-eclampsia occurred in 73% and 71% of these showed acceleration of disease during the pregnancy. All the patients had diabetic retinopathy, though proliferative retinopathy was diagnosed and treated in only 54.5.% pre pregnancy. The retinopathy progressed, requiring laser therapy, in 45.4%. Macular edema was noted in 6 of the patients. Other diabetic complications included peripheral and autonomic neuropathy in 8 patients. Conclusion: Pregnancy induced progression is seen in the decline of renal functions. Patients with diabetic nephropathy were found to have a > 40% chance of accelerated progression of their disease as a result of pregnancy. Forty-five percent of the patients had permanent decline in GFR in association with pregnancy. (author)

Histoplasmosis and blastomycosis respond well to antifungal treatment, but rela...

  11. Controlling endemic cholera with oral vaccines.

    2007-11-01

    Full Text Available BACKGROUND: Although advances in rehydration therapy have made cholera a treatable disease with low case-fatality in settings with appropriate medical care, cholera continues to impose considerable mortality in the world's most impoverished populations. Internationally licensed, killed whole-cell based oral cholera vaccines (OCVs have been available for over a decade, but have not been used for the control of cholera. Recently, these vaccines were shown to confer significant levels of herd protection, suggesting that the protective potential of these vaccines has been underestimated and that these vaccines may be highly effective in cholera control when deployed in mass immunization programs. We used a large-scale stochastic simulation model to investigate the possibility of controlling endemic cholera with OCVs. METHODS AND FINDINGS: We construct a large-scale, stochastic cholera transmission model of Matlab, Bangladesh. We find that cholera transmission could be controlled in endemic areas with 50% coverage with OCVs. At this level of coverage, the model predicts that there would be an 89% (95% confidence interval [CI] 72%-98% reduction in cholera cases among the unvaccinated, and a 93% (95% CI 82%-99% reduction overall in the entire population. Even a more modest coverage of 30% would result in a 76% (95% CI 44%-95% reduction in cholera incidence for the population area covered. For populations that have less natural immunity than the population of Matlab, 70% coverage would probably be necessary for cholera control, i.e., an annual incidence rate of < or = 1 case per 1,000 people in the population. CONCLUSIONS: Endemic cholera could be reduced to an annual incidence rate of < or = 1 case per 1,000 people in endemic areas with biennial vaccination with OCVs if coverage could reach 50%-70% depending on the level of prior immunity in the population. These vaccination efforts could be targeted with careful use of ecological data.

    Of the glomerulonephritis associated with sarcoidosis, membranous nephropathy (MN) is the most prevalent. Coincidence or a causal relationship between these two diseases is unclear. Here, we present for the first time a high prevalence of PLA2R-related MN among patients with MN associated with active sarcoidosis. Our results suggest some causal link between sarcoidosis and PLA2R-related MN. Detection of anti-PLA2R antibodies in serum or PLA2R antigen in biopsy should not be taken as evidence against a secondary cause, particularly sarcoidosis. This important observation can affect treatment decision in these patients.

    Full Text Available IgA nephropathy is the most common type of the glomerulonephritis all over the world. However, its clinical presentation is variable, as is the underlying histopathological lesion. We report herein a case of an adult with steroid responsive minimal change disease and IgA mesangial deposits. During the first two weeks of therapy with prednisolone, the patient reported dramatic improvement in his clinical condition and remitted his disease. Unfortunately, at the end of the second month of prednisolone therapy, an acute flare of viral hepatitis was diagnosed. Interes-tingly, the acute viral flare was without a concomitant relapse of proteinuria.

    Diabetic nephropathy (DN) is the most common pathology contributing to the development of chronic kidney disease (CKD). DN caused by hypertension and unmitigated inflammation in diabetics, renders the kidneys unable to perform normally, and leads to renal fibrosis and organ failure. The increasing global prevalence of DN has been directly attributed to rising incidences of Type II diabetes, and is now the largest non-communicable cause of death worldwide. Despite the high morbidity, successful new treatments for DN are lacking. This review seeks to provide new insight on emerging clinical candidates under investigation for the treatment of DN.

    The climate change in the Mediterranean area is expected to have significant impacts on the aquatic ecosystems and particular in the mountain rivers and streams that often host important species such as the Salmo farioides, Karaman 1938. These impacts will most possibly affect the habitat availability for various aquatic species resulting to an essential alteration of the water requirements, either for dams or other water abstractions, in order to maintain the essential levels of ecological flow for the rivers. The main scope of this study was to assess potential climate change impacts on the hydrological patterns and typical biota for a south-western Balkan mountain river, the Acheloos. The altered flow regimes under different emission scenarios of the Intergovernmental Panel on Climate Change (IPCC) were estimated using a hydrological model and based on regional climate simulations over the study area. The Indicators of Hydrologic Alteration (IHA) methodology was then used to assess the potential streamflow alterations in the studied river due to predicted climate change conditions. A fish habitat simulation method integrating univariate habitat suitability curves and hydraulic modeling techniques were used to assess the impacts on the relationships between the aquatic biota and hydrological status utilizing a sentinel species, the West Balkan trout. The most prominent effects of the climate change scenarios depict severe flow reductions that are likely to occur especially during the summer flows, changing the duration and depressing the magnitude of the natural low flow conditions. Weighted Usable Area-flow curves indicated the limitation of suitable habitat for the native trout. Finally, this preliminary application highlighted the potential of science-based hydrological and habitat simulation approaches that are relevant to both biological quality elements (fish) and current EU Water policy to serve as efficient tools for the estimation of possible climate

    The Bayash are a branch of Romanian speaking Roma living dispersedly in Central, Eastern, and Southeastern Europe. To better understand the molecular architecture and origin of the Croatian Bayash paternal gene pool, 151 Bayash Y chromosomes were analyzed for 16 SNPs and 17 STRs and compared with European Romani and non-Romani majority populations from Europe, Turkey, and South Asia. Two main layers of Bayash paternal gene pool were identified: ancestral (Indian) and recent (European). The reduced diversity and expansion signals of H1a patrilineages imply descent from closely related paternal ancestors who could have settled in the Indian subcontinent, possibly as early as between the eighth and tenth centuries AD. The recent layer of the Bayash paternal pool is dominated by a specific subset of E1b1b1a lineages that are not found in the Balkan majority populations. At least two private mutational events occurred in the Bayash during their migrations from the southern Balkans toward Romania. Additional admixture, evident in the low frequencies of typical European haplogroups, J2, R1a, I1, R1b1b2, G, and I2a, took place primarily during the early Bayash settlement in the Balkans and the Romani bondage in Romania. Our results indicate two phenomena in the Bayash and analyzed Roma: a significant preservation of ancestral H1a haplotypes as a result of considerable, but variable level of endogamy and isolation and differential distribution of less frequent, but typical European lineages due to different patterns of the early demographic history in Europe marked by differential admixture and genetic drift.

    Full Text Available Monoclonal antibodies applied in clinical oncology present a therapeutic promise for many patients with cancer. Nevertheless these expensive protocols are associated with extremely high acquisition and administration costs. The issue of societal affordability of such treatment options is particularly at stake among middle income European economies. Medicines Agency of Serbia issues regular annual reports on public expenditure on pharmaceuticals since 2004. According to these official data total public expenditure on drugs doubled from 2004-2012 (from € 339,279,304 to € 742,013,976. During the same nine years public expenditure on antineoplastic pharmaceuticals was rising at much faster pace, approximately five times from € 10,297,616 in 2004 to € 51,223,474 in 2012. Absolutely record growth belongs to the value of turnover of monoclonal antibodies indicated in diverse malignancies. These costs became almost twenty times higher in 2012 compared to 2004 (€ 19,687,454 towards € 1,033,313 in the past. National pharmaceutical expenditure trend projections in this country show strong recovery in 2012 after severe blow to the overall health care market imposed by the worldwide crisis. Universal health insurance coverage and sustainable health care financing provision will remain difficult issues for Balkan economies in years to come. Although monoclonal antibodies exhibit undisputed therapeutic efficiency in certain malignant disorders, cost-effectiveness estimates must be taken into consideration by policy makers deciding on reimbursement.http://dx.doi.org/10.7175/fe.v15i1.909

    Energy crisis, climate changes, and biodiversity losses have reinforced the drive for more ecologically-based approaches for environmental management. Such approaches are characterized by the use of organisms rather than energy-consuming technologies. Although earthworms are believed to be potentially useful organisms for managing ecosystem services, there is actually no quantification of such a trend in literature. This bibliometric analysis aimed to measure the evolution of the association of "earthworms" and other terms such as ecosystem services (primary production, nutrient cycling, carbon sequestration, soil structure, and pollution remediation), "ecological engineering" or "biodiversity," to assess their convergence or divergence through time. In this aim, we calculated the similarity index, an indicator of the paradigmatic proximity defined in applied epistemology, for each year between 1900 and 2009. We documented the scientific fields and the geographical origins of the studies, as well as the land uses, and compare these characteristics with a 25 years old review on earthworm management. The association of earthworm related keywords with ecosystem services related keywords was increasing with time, reflecting the growing interest in earthworm use in biodiversity and ecosystem services management. Conversely, no significant increase in the association between earthworms and disciplines such as ecological engineering or restoration ecology was observed. This demonstrated that general ecologically-based approaches have yet to emerge and that there is little exchange of knowledge, methods or concepts among balkanized application realms. Nevertheless, there is a strong need for crossing the frontiers between fields of application and for developing an umbrella discipline to provide a framework for the use of organisms to manage ecosystem services.

    Full Text Available A new homogenous earthquake catalogue covering Bulgaria and the surrounding Balkan area has been created with intention of performing a consistent seismic hazard assessment across the region. In keeping with modern requirements of cataloguing seismicity, this catalogue has been made homogenous as far as possible with regards to magnitude, which has been provided on any of four different reported scales for each event; mb, Ms, Mw and ML. A key historical catalogue for the region has been used to represent the early instrumental period of earthquake recording (1900 to 1963, whilst data have been obtained from the International Seismological Centre (ISC, National Earthquake Information Center (NEIC and National Observatory of Athens (NOA to cover the instrumental period of earthquake recording (1964 to 2004. ISC data have also been used to develop a new mb→Ms magnitude conversion equation for the catalogued region. Application of this new magnitude conversion relation, in combination with other selected magnitude scale correlations, ensures reported magnitudes can be systematically rendered onto homogenized Ms and Mw scales for all earthquakes. This catalogue contains 3681 events with homogenized magnitudes ≥4.0 Mw, for the time interval 1900 to 2004 (inclusive, located in the region bounded by 39°–45° N, 19°–29° E, at focal depths of 0.0 km to 401.0 km and in a magnitude range 4.0≤Mw≤7.2. Selected large magnitude (M≥6.0 Ms earthquakes have had their reported magnitudes reassessed – and adjusted if necessary – in light of work by other authors. Applied statistical approaches aimed at determining the lower threshold to magnitude completeness suggest this catalogue is complete down to a homogenized surface-wave magnitude of 4.6 Ms.

    Full Text Available The aim of this study was to compare the protein and fatty acid fractions of Balkan donkey and human milk in the early lactation stage (40 and 90 day. This study revealed that donkey milk contains αs1-casein (1.38-1.89 g/L and higher concentration of β-casein (0.1-0.55 g/L in comparison to human milk. The concentration of α-lactalbumin increased during the lactation phases from 40 to 90 days in both types of milk. Donkey milk contained β-lactoglobulin in low concentrations which decreased to 90th day of lactation. Donkey milk was particularly rich in two whey proteins, lactoferrin and lysozyme, which were found to have molecular weight of approximately 76 kDa and 14.9-15.4 kDa, respectively. The content of lysozyme in donkey milk ranged from 2.39 to 2.97 g/L, while human milk contained 30-50 times lower concentrations of lysozyme in comparison to donkey milk. Thus, donkey milk contained also a higher concentration of lactoferrin (0.012-0.25 g/L than it was found in the human milk. Lysozyme and lactoferrin content in donkey milk increased during the period from 40th to 90th day of lactation. The percentage of total SFA, MUFA and PUFA was similar in donkey and human milk. The content of essential fatty acids increased during 40-90 days of lactation and was approximately 2.5 times higher in comparison to human milk.

  2. Tectonic, magmatic, and metallogenic evolution of the Late Cretaceous arc in the Carpathian-Balkan orogen

    The Apuseni-Banat-Timok-Srednogorie Late Cretaceous magmatic arc in the Carpathian-Balkan orogen formed on the European margin during closure of the Neotethys Ocean. It was subsequently deformed into a complex orocline by continental collisions. The Cu-Au mineralized arc consists of geologically distinct segments: the Apuseni, Banat, Timok, Panagyurishte, and Eastern Srednogorie segments. New U-Pb zircon ages and geochemical whole rock data for the Banat and Apuseni segments are combined with previously published data to reconstruct the original arc geometry and better constrain its tectonic evolution. Trace element and isotopic signatures of the arc magmas indicate a subduction-enriched source in all segments and variable contamination by continental crust. The magmatic arc was active for 25 Myr (~92-67 Ma). Across-arc age trends of progressively younger ages toward the inferred paleo-trench indicate gradual steepening of the subducting slab away from the upper plate European margin. This leads to asthenospheric corner flow in the overriding plate, which is recorded by decreasing 87Sr/86Sr (0.70577 to 0.70373) and increasing 143Nd/144Nd (0.51234 to 0.51264) ratios over time in some segments. The close spatial relationship between arc magmatism, large-scale shear zones, and related strike-slip sedimentary basins in the Timok and Pangyurishte segments indicates mild transtension in these central segments of the restored arc. In contrast, the Eastern Srednogorie segment underwent strong orthogonal intraarc extension. Segmental distribution of tectonic stress may account for the concentration of rich porphyry Cu deposits in the transtensional segments, where lower crustal magma storage and fractionation favored the evolution of volatile-rich magmas.

    Full Text Available Fraxinus angustifolia Vahl is a species native in the north-western Balkans, where it has a divided range. Most of its range is located in flood-prone riparian sites in the Pannonian plain but the species is also found on humid sites along some rivers in the Submediterranean region. We analysed morphologic variation within and between five populations (14 trees/population located in the Subpannonian and Submediterranean region of Slovenia. Thirty two characters were assessed on ca. 80 leaves from each tree which were divided depending on exposure to sunlight (sun and shade leaves, and 8 traits on each fruit (ca. 50 fruits/tree. A hierarchically designed experiment using analysis of variance confirmed the significant contribution of all the analysed hierarchical levels of variation to the total variation. The results show that the differences between the trees in a single population are the greatest factor of variability of leaves, followed by differences between populations and differences which are the result of variation in exposure to sunlight. Leaves in shade positions are typically larger than those in sunny positions, and they have broader and shorter-pointed leaflets; in this feature they are very similar to the leaves of F. excelsior. Stepwise discriminant analysis showed that the traits which refer to the leaflet number and length are the best differentiating traits between individual populations. The Submediterranean population Dragonja stands out with the smallest leaves and the population Lijak from the same region is the most similar to Dragonja for most morphological traits. In general, phenotypic differences between the Subpannonian and the Submediterranean populations of F. angustifolia are minor and indistinct. Based on the differences ascertained by the study, we can only confirm the presence of F. angustifolia subsp. oxycarpa (Bieb. ex Willd. Franco et Rocha Alfonso in this part of its natural range.

  4. Concentration and characteristics of uranium isotopes in water collected in central Italy and Balkan regions

    International Nuclear Information System (INIS)

    Full text: Uranium is a naturally occurring, ubiquitous heavy metal found in the environment in various chemical forms in all soils, rocks, seas and oceans. It is also present in air, food and drinking water. Due to its widespread existence in nature, uranium isotopes (238U, 234U and 235U) have become one of the most important source of natural radioactivity and make a significant contribution to external and internal dose to population. Uranium isotopes enter the human body mainly through ingestion, and by inhalation to a considerably smaller degree. Hence the internal radiation exposure for members of the public can be evaluated through the intake of the radionuclides from both food and water. Pietrzak-Flis et al., have investigated the uranium intake fractions of the different pathways, and concluded that the uranium intake from water by man is the most important pathway which contributes the largest fraction (75.1%-76.9%) of uranium intake. For the purpose of estimating the radiological impact of uranium isotopes in water to the residents, some natural water samples were collected in central Italy and Balkan Regions and analysed in the laboratory of Italian Environmental Protection Agency and Technical Services (APAT). The activity concentrations of 238U, 234U and 235U were obtained. The radioanalytical procedure used for determination of uranium isotopes in water mainly includes steps of uranium pre-concentration, mineralization, separation by a Microthene- TOPO column, electrodeposition and measurement by alpha-spectrometry. Based on the obtained activity concentrations of uranium isotopes in drinking water, annual consumption rate of the water, and the dose conversion factor per unit intake given by the International Commission on Radiological Protection, the annual effective dose resulting from 1-year ingestion for the adult population was calculated.

    Diabetic nephropathy is the leading and possibly the most devastating complication of diabetes, with a prevalence ranging from 25 to 40 % in diabetic individuals, and as such represents an important challenge for public health worldwide. As a major cause of end-stage renal disease, diabetic nephropathy also accounts for a large proportion of deaths in diabetic individuals. To date, therapeutic options for overt diabetic nephropathy include medical interventions to reduce blood glucose levels and to control blood pressure and proteinuria. Recent evidence suggests a strong role for inflammation in the development and progression of diabetic nephropathy. Various immune cells, cytokines and chemokines have been implicated in the onset of diabetic nephropathy, while immune-related transcription factors and adhesion molecules have been correlated with the establishment of a renal proinflammatory microenvironment. Both inflammation and immune activation may promote severe distress in the kidney, with subsequent increased local fibrosis, ultimately leading to the development of end-stage renal disease. Stem cells are undifferentiated cells capable of regenerating virtually any organ or tissue and bearing important immunoregulatory and anti-inflammatory properties. Due to the aforementioned considerations, significant interest has been ignited with regard to the use of stem cells as novel therapeutics for diabetic nephropathy. Here, we will be examining in detail how anti-inflammatory properties of different populations of stem cells may offer novel therapy for the treatment of diabetic nephropathy.

    This study aimed at investigating the association between haemostatic biomarkers, proinflammatory, and anti-inflammatory cytokines with chronic kidney disease in type 1 diabetic patients. Patients were divided into two groups: with nephropathy (albuminuria ≥ 30 mg/g and/or GFR < 60 mL/min/1.73 m2), n = 65; and without nephropathy (albuminuria < 30 mg/g and GFR ≥ 60 mL/min/1.73 m2), n = 60. INF-γ, IL-6, IL-10, and TNF-α plasma levels were determined by flow cytometry. VWF, ADAMTS13 antigen, and D-Dimer plasma levels were determined by enzyme-linked immunosorbent assay and ADAMTS13 activity was assessed by fluorescence resonance energy transfer assay. Elevated levels of INF-γ, VWF, ADAMTS13 antigen, D-Dimer, and reduced ADAMTS13 activity/antigen ratio were observed in patients with nephropathy as compared to those without nephropathy (P = 0.001, P < 0.001, P < 0.001, P < 0.001, and P < 0.001, resp.). Cytokines and haemostatic biomarkers remained associated with nephropathy after adjustments (use of statin, acetylsalicylic acid, angiotensin converting enzyme inhibitor, and angiotensin antagonist). INF-γ, TNF-α, and IL-10 significantly correlated with haemostatic biomarkers. Inflammatory and hypercoagulability status are associated with nephropathy in type 1 diabetes mellitus and an interrelationship between them may play an important role in pathogenesis of diabetic nephropathy.

    2014-09-01

    Full Text Available Background/Aims: Our aim was to explore the molecular mechanism underlying development of IgA nephropathy and discover candidate agents for IgA nephropathy. Methods: The differentially expressed genes (DEGs between patients with IgA nephropathy and normal controls were identified by the data of GSE35488 downloaded from GEO (Gene Expression Omnibus database. The co-expressed gene pairs among DEGs were screened to construct the gene-gene interaction network. Gene Ontology (GO enrichment analysis was performed to analyze the functions of DEGs. The biologically active small molecules capable of targeting IgA nephropathy were identified using the Connectivity Map (cMap database. Results: A total of 55 genes involved in response to organic substance, transcription factor activity and response to steroid hormone stimulus were identified to be differentially expressed in IgA nephropathy patients compared to healthy individuals. A network with 45 co-expressed gene pairs was constructed. DEGs in the network were significantly enriched in response to organic substance. Additionally, a group of small molecules were identified, such as doxorubicin and thapsigargin. Conclusion: Our work provided a systematic insight in understanding the mechanism of IgA nephropathy. Small molecules such as thapsigargin might be potential candidate agents for the treatment of IgA nephropathy.

    Full Text Available Background: Atherogenic lipid profile is reported to become pronounced with onset of nephropathy. Lipid ratios also indicate atherogenic dyslipidemia. Lipoprotein (a [(Lp(a] considered as an independent risk factor for cardiovascular diseases (CVD, may play an important role in development and progression of nephropathy in type 2 diabetes mellitus (T2DM. The present study aimed to assess atherogenic dyslipidemia in T2DM and diabetic nephropathy patients. Methods: Total cholesterol (TC, triglycerides(Tgl, high density lipoprotein (HDL, low density lipoprotein (LDL, very low density lipoprotein (VLDL, Lp(a, lipid ratios: TC/HDL, Tgl/HDL, LDL/HDL, non-HDL cholesterol and atherogenic index (AI was assessed in T2DM (n=35, diabetic nephropathy (n=30 and healthy individuals (n=30. Means of biochemical parameters were compared by ANOVA (analysis of variance. Pearson correlation was performed to study the association between parameters. Receiver operating characteristics (ROC curve analysis was done to assess the predictive ability of the variables. Results: Atherogenic dyslipidemia with elevated Lp(a, TC, Tgl, VLDL, LDL, non-HDL cholesterol, lipid ratios, AI and low HDL levels were observed in both T2DM patients with and without nephropathy when compared to controls. Significantly high Tgl/HDL, TC/HDL and AI were observed in diabetic nephropathy when compared to T2DM. Conclusion: T2DM and diabetic nephropathy are associated with dyslipidemia which was more pronounced in diabetic nephropathy. Elevated Lp(a levels may be considered as an independent CVD risk marker in T2DM and diabetic nephropathy patients along with atherogenic lipid ratio indicators.

    2009-01-01

    BACKGROUND Idiopathic membranous nephropathy, a common form of the nephrotic syndrome, is an antibody-mediated autoimmune glomerular disease. Serologic diagnosis has been elusive because the target antigen is unknown. METHODS We performed Western blotting of protein extracts from normal human glomeruli with serum samples from patients with idiopathic or secondary membranous nephropathy or other proteinuric or autoimmune diseases and from normal controls. We used mass spectrometry to analyze the reactive protein bands and confirmed the identity and location of the target antigen with a monospecific antibody. RESULTS Serum samples from 26 of 37 patients (70%) with idiopathic but not secondary membranous nephropathy specifically identified a 185-kD glycoprotein in non-reduced glomerular extract. Mass spectrometry of the reactive protein band detected the M-type phospholipase A2 receptor (PLA2R). Reactive serum specimens recognized recombinant PLA2R and bound the same 185-kD glomerular protein as did the monospecific anti-PLA2R antibody. Anti-PLA2R autoantibodies in serum samples from patients with membranous nephropathy were mainly IgG4, the predominant immunoglobulin subclass in glomerular deposits. PLA2R was expressed in podocytes in normal human glomeruli and colocalized with IgG4 in immune deposits in glomeruli of patients with membranous nephropathy. IgG eluted from such deposits in patients with idiopathic membranous nephropathy, but not in those with lupus membranous or IgA nephropathy, recognized PLA2R. CONCLUSIONS A majority of patients with idiopathic membranous nephropathy have antibodies against a conformation-dependent epitope in PLA2R. PLA2R is present in normal podocytes and in immune deposits in patients with idiopathic membranous nephropathy, indicating that PLA2R is a major antigen in this disease. PMID:19571279

    Full Text Available Background: Nephropathy is one of the major complications among the patients having type 1 or long term Type 2 diabetes and there are various studies that suggest its genetic predisposition. A 287 bp insertion/deletion (I/D polymorphism of the gene encoding angiotensin-I converting enzyme (ACE is shown to have association with diabetic nephropathy. Aim: To identify the association of ACE I/D polymorphism with subjects having diabetic nephropathy.Materials and methods: The present study examined the prevalence of ACE insertion/deletion polymorphism among 91 Bengali individuals from Eastern India. Among them 30 individuals belong to diabetic nephropathy (DN, 30 individuals having diabetes without nephropathy (DM and 31 normal controls. The DNA samples of studied subjects were genotyped using polymerase chain reaction.Results: The frequency of DD, ID and II genotypes in patients having diabetic nephropathy (DN were found to be 26.7%, 53.3% and 20.0% respectively, whereas the same for only diabetic patients (DM were 26.7%, 50.0%and 23.3% respectively. The frequencies of the same genotypes among the normal controls were found to be 9.68%, 64.5% and 25.8% respectively. Inspite of a slightly higher odds ratio for DD genotypes among DM and DN subjects in comparison to the normal group the distribution pattern of DD genotype did not differ significantly within the three cohorts. The frequency of D allele among the patients having diabetic nephropathy, diabetic without nephropathy and control subjects was found to be 0.533, 0.516 and 0.420 respectively. This distribution pattern also did not differ significantly (χ2=1.859, p>0.05.Conclusion: No significant association was found between ACE I/D polymorphism with diabetic nephropathy patients from Bengali caste population.

    An outbreak of unexplained and severe kidney disease, "Mesoamerican Nephropathy," in mostly young, male sugar cane workers emerged in Central America in the late 1990's. As a result, an estimated 20,000 individuals have died, to date. Unfortunately, and with great consequence to human life, the etiology of the outbreak has yet to be identified. The sugarcane fields in Chichigalpa, Chinandega, Nicaragua, have been involved in the outbreak, and during our initial investigation, we interviewed case patients who experienced fever, nausea and vomiting, arthralgia, myalgia, headache, neck and back pain, weakness, and paresthesia at the onset of acute kidney disease. We also observed a heavy infestation of rodents, particularly of Sigmodon species, in the sugarcane fields. We hypothesize that infectious pathogens are being shed through the urine and feces of these rodents, and workers are exposed to these pathogens during the process of cultivating and harvesting sugarcane. In this paper, we will discuss the epidemic in the Chichigalpa area, potential pathogens responsible for Mesoamerican Nephropathy, and steps needed in order to diagnose, treat, and prevent future cases from occurring.

    Full Text Available Multiple myeloma is an incurable plasma cell malignancy that is often accompanied by renal failure; there are a number of potential causes of this, of which cast nephropathy is the most important. Renal failure is highly significant in myeloma, as patient survival can be stratified by the severity of the renal impairment. Consequently, there is an ongoing focus on the pathological basis of cast nephropathy and the optimal treatment regimens in this setting, including effective chemotherapy regimens to reduce light chain production and emerging extracorporeal techniques to remove circulating light chains. This paper bridges recent advances in the pathogenesis and management of cast nephropathy in multiple myeloma.

    Full Text Available Aims: To investigate the potential role of renalase in adriamycin nephropathy and the effect of lisinopril on the regulation of renalase. Methods: Adriamycin nephropathy was induced in male Wistar rats (n=12 by a single injection of adriamycin at 2 mg/kg body weight. Rats were then randomly assigned to a model group or a treatment group, to which were administered distilled water or the angiotensin converting enzyme inhibitor lisinopril, respectively, for 12 weeks. Six normal rats served as controls. At the end of study, physiological parameters and systolic blood pressure were measured. Glomerulosclerosis and tubulointerstitial injury were assessed by histopathology Renalase protein expression in kidney was quantified by immunohistochemistry and immunoblotting. The serum concentration and urinary excretion of renalase were determined by enzyme-linked immunosorbent assay. Results: In model group rats, proteinuria and systolic blood pressure were elevated. Increased serum renalase concentration was observed; however, renalase protein expression in the kidney was significantly decreased. Compared with the model group, decreased proteinuria, lower systolic blood pressure, and fewer morphologic lesions were detected in the treatment group. Although levels of serum renalase were similar, accumulation of renalase in urine and kidney tissue increased notably in the treatment group compared with the model group. Conclusions: This study suggests that renalase may be involved in the process of adriamycin-induced renal injuries. Lisinopril may attenuate adriamycin-induced kidney injury by controlling blood pressure, which may be partially attributed to the renalase expression and secretion.

    To identify biomarker candidates associated with early IgA nephropathy (IgAN) and thin basement membrane nephropathy (TBMN), the most common causes presenting isolated hematuria in childhood, a proteomic approach of urinary exosomes from early IgAN and TBMN patients was introduced. The proteomic results from the patients were compared with a normal group to understand the pathophysiological processes associated with these diseases at the protein level. The urinary exosomes, which reflect pathophysiological processes, collected from three groups of young adults (early IgAN, TBMN, and normal) were trypsin-digested using a gel-assisted protocol, and quantified by label-free LC-MS/MS, using an MS(E) mode. A total of 1877 urinary exosome proteins, including cytoplasmic, membrane, and vesicle trafficking proteins, were identified. Among the differentially expressed proteins, four proteins (aminopeptidase N, vasorin precursor, α-1-antitrypsin, and ceruloplasmin) were selected as biomarker candidates to differentiate early IgAN from TBMN. We confirmed the protein levels of the four biomarker candidates by semi-quantitative immunoblot analysis in urinary exosomes independently prepared from other patients, including older adult groups. Further clinical studies are needed to investigate the diagnostic and prognostic value of these urinary markers for early IgAN and TBMN. Taken together, this study showed the possibility of identifying biomarker candidates for human urinary diseases using urinary exosomes and might help to understand the pathophysiology of early IgAN and TBMN at the protein level.

    A detailed tephrostratigraphic record, which dates back to Marine Isotope Stage (MIS) 5b (ca. 91 kyr), has been established from a 17.76 m long core (Co1215) from Lake Prespa (Macedonia, Albania and Greece). A total of eleven tephra and cryptotephra layers (PT0915-1 to PT0915-11) were identified, using XRF scanning, magnetic susceptibility measurements, and macro- and microscopic inspection of the sediments. The major element composition of glass shards and/or micro-pumice fragments indicates that the tephras and cryptotephras originate from the explosive volcanism of Italy. Eight tephra and cryptotephra layers were correlated with specific volcanic eruptions: the AD 512 eruption of Somma-Vesuvius (1438 cal yr BP), the Mercato eruption of Somma-Vesuvius (8890 ± 90 cal yr BP), the Tufi Biancastri/LN1-LN2 eruption of the Campi Flegrei (14 749 ± 523 cal yr BP and 15 551 ± 621 cal yr BP), the SMP1-e/Y-3 eruption of the Campi Flegrei (30 000-31 000 cal yr BP), the Campanian Ignimbrite/Y-5 eruption of the Campi Flegrei (39 280 ± 110 cal yr BP), the SMP1-a event of Ischia Island (around 44 000 cal yr BP) and the Green Tuff/Y-6 eruption of Pantelleria Island (around 45 000 cal yr BP). One tephra could be attributed to the volcanic activity of Mount Etna, but probably represents an unknown eruption at ca. 60 000 cal yr BP. Cryptotephras PT0915-6 and PT0915-10 remain unclassified so far, but according to the presented age-depth model these would have been deposited around 35 000 and 48 500 cal yr BP, respectively. Some of the tephras and cryptotephras are recognised for the first time in the Balkan region. The tephrostratigraphic work provides important information about ash dispersal and explosion patterns of source volcanoes and can be used to correlate and date geographically distant paleoenvironmental and archaeological archives in the central Mediterranean region.

    Highlights: • {sup 1}H NMR spectroscopy was employed to study urinary metabolite profile in diabetic mouse models. • Mouse urinary metabolome showed major changes that are also found in human diabetic nephropathy. • These models can be new tools to study urinary biomarkers that are relevant to human disease. - Abstract: Countering the diabetes pandemic and consequent complications, such as nephropathy, will require better understanding of disease mechanisms and development of new diagnostic methods. Animal models can be versatile tools in studies of diabetic renal disease when model pathology is relevant to human diabetic nephropathy (DN). Diabetic models using endothelial nitric oxide synthase (eNOS) knock-out mice develop major renal lesions characteristic of human disease. However, it is unknown whether they can also reproduce changes in urinary metabolites found in human DN. We employed Type 1 and Type 2 diabetic mouse models of DN, i.e. STZ-eNOS{sup −/−} C57BLKS and eNOS{sup −/−} C57BLKS db/db, with the goal of determining changes in urinary metabolite profile using proton nuclear magnetic resonance (NMR). Six urinary metabolites with significantly lower levels in diabetic compared to control mice have been identified. Specifically, major changes were found in metabolites from tricarboxylic acid (TCA) cycle and aromatic amino acid catabolism including 3-indoxyl sulfate, cis-aconitate, 2-oxoisocaproate, N-phenyl-acetylglycine, 4-hydroxyphenyl acetate, and hippurate. Levels of 4-hydroxyphenyl acetic acid and hippuric acid showed the strongest reverse correlation to albumin-to-creatinine ratio (ACR), which is an indicator of renal damage. Importantly, similar changes in urinary hydroxyphenyl acetate and hippurate were previously reported in human renal disease. We demonstrated that STZ-eNOS{sup −/−} C57BLKS and eNOS{sup −/−} C57BLKS db/db mouse models can recapitulate changes in urinary metabolome found in human DN and therefore can be

    Endemic/epidemic dengue viruses (DEN) that are transmitted among humans by the mosquito vectors Aedes aegypti and Aedes albopictus are hypothesized to have evolved from sylvatic DEN strains that are transmitted among nonhuman primates in West Africa and Malaysia by other Aedes mosquitoes. We tested this hypothesis with phylogenetic studies using envelope protein gene sequences of both endemic/epidemic and sylvatic strains. The basal position of sylvatic lineages of DEN-1, -2, and -4 suggested that the endemic/epidemic lineages of these three DEN serotypes evolved independently from sylvatic progenitors. Time estimates for evolution of the endemic/epidemic forms ranged from 100 to 1,500 years ago, and the evolution of endemic/epidemic forms represents relatively recent events in the history of DEN evolution. Analysis of envelope protein amino acid changes predicted to have accompanied endemic/epidemic emergence suggested a role for domain III in adaptation to new mosquito and/or human hosts.

    Full Text Available Abstract Introduction Oxalate nephropathy has various etiologies and remains a rare cause of renal failure. To the best of our knowledge, we report the first case of oxalate nephropathy following octreotide therapy. Case presentation We report the case of a 78-year-old Caucasian man taking chronic octreotide treatment for acromegaly who presented with acute oxalate nephropathy after antibiotic therapy. The diagnosis was confirmed by urinary analysis and a kidney biopsy. The recovery of renal function was favorable after hydration and withdrawal of octreotide therapy. Conclusions Oxalate nephropathy should be suspected in patients at risk who present with acute kidney injury after prolonged antibiotic treatment. This diagnosis should be distinguished from immuno-allergic interstitial nephritis and requires specific care. The evolution of this condition may be favorable if the pathology is identified correctly. Octreotide therapy should be considered a risk factor for enteric oxaluria.

    Full Text Available IgA nephropathy is the most common glomerulonephritis worldwide and typically has minimal signs for chronicity in histopathology at the time of initial presentation. Pseudotumor cerebri (PTC is characterized by increased intracranial pressure in the absence of any intracranial lesions, inflammation, or obstruction. PTC has been reported in renal transplant and dialysis patients, but we are unaware of any reports of pseudotumor cerebri in patients with IgA nephropathy. We report a case of a young female who presented with signs and symptoms of pseudotumor cerebri and was subsequently diagnosed with IgA nephropathy and end-stage renal disease. To our knowledge this is the first report of IgA nephropathy presenting as end-stage renal disease in a patient who presented with pseudotumor cerebri.

  13. Association of liver cirrhosis related IgA nephropathy with portal hypertension

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    A high incidence of IgA nephropathy has been reported in patients with liver cirrhosis, though, clinically evident nephrotic syndrome is very uncommon. Impaired hepatic clearance of circulating IgA immune complexes and subsequent deposition in renal glomeruli has been considered principally in the pathogenesis of liver cirrhosis associated IgA nephropathy. Here we report on a patient with cryptogenic liver cirrhosis and splenic vein thrombosis, who presented with nephrotic syndrome. Renal biopsy showed findings consistent with IgA nephropathy. Lower endoscopy showed features of portal hypertensive colopathy. Following initiation of propranolol and anticoagulant treatment to reduce portal pressure, a gradual decrease of proteinuria and hematuria to normal range was noted. The potential pathogenetic role of portal hypertension in the development of IgA nephropathy in cirrhotic patients is discussed.

    Malaria infection is still to be considered a major public health problem in those 106 countries where the risk of contracting the infection with one or more of the Plasmodium species exists. According to estimates from the World Health Organization, over 200 million cases and about 655.000 deaths have occurred in 2010. Estimating the real health and social burden of the disease is a difficult task, because many of the malaria endemic countries have limited diagnostic resources, especially in rural settings where conditions with similar clinical picture may coexist in the same geographical areas. Moreover, asymptomatic parasitaemia may occur in high transmission areas after childhood, when anti-malaria semi-immunity occurs. Malaria endemicity and control activities are very complex issues, that are influenced by factors related to the host, to the parasite, to the vector, to the environment and to the health system capacity to fully implement available anti-malaria weapons such as rapid diagnostic tests, artemisinin-based combination treatment, impregnated bed-nets and insecticide residual spraying while waiting for an effective vaccine to be made available.

    Cholera remains a major public health threat for the developing countries. Since the causative agent, Vibrio cholerae, is autochthonous to aquatic environment, it is not possible to eradicate the agent of the disease. Hydroclimatology based prediction and prevention strategies can be implemented in disease susceptible regions for reducing incidence rates. However, the precise role of hydrological and climatological processes, which will further aid in development of suitable prediction models, in creating spatial and temporal environmental conditions favorable for disease outbreak has not been adequately quantified. Here, we show distinction between seasonality and occurrence of cholera in epidemic and non-endemic regions. Using historical cholera mortality data, from the late 1800s for 27 locations in the Indian subcontinent, we show that non-endemic regions are generally located close to regional river systems but away from the coasts and are characterized by single sporadic outbreak in a given year. Increase in air temperature during the low river flow season increases evaporation, leading to an optimal salinity and pH required for bacterial growth. Thereafter, monsoonal rainfall, leads to interactions of contaminated river waters via human activity resulting in cholera epidemics. Endemic regions are located close to coasts where cholera outbreak occurs twice (spring and fall) in a year. Spring outbreak is generally associated with intrusion of bacterial seawater to inland whereas the fall peak is correlated with widespread flooding and cross-contamination of water resources via increased precipitation. This may be one of the first studies to hydroclimatologically quantitatively the seasonality of cholera in both endemic and non-endemic regions. Our results prompt the need of region and cause-specific prediction models for cholera, employing appropriate environmental determinants.

    International Nuclear Information System (INIS)

    Objective: To study the changes of plasma levels of homocysteine (Hcy) and urinary albumin contents in patients with type 2 diabetes complicated with nephropathy. Methods: Plasma Hcy (with fluorescence immunoassay) fasting glucose, BUN, Cr (with biochemistry) levels and urinary albumin contents (with RIA) were determined in 36 DM2 patients without nephropathy, 30 DM2 patients with nephropathy and 30 controls. Results: The fasting blood glucose levels in the 2 groups of diabetic patients were not much different. Again, the BUN and Cr levels in the 3 groups of patients were about the same. The plasma Hcy levels in the group of patients with diabetic nephropathy were significantly higher than those in both controls and DM2 patients without nephropathy (all P<0.01). Conclusion: Hyperhomocysteinemia is a risk factor for nephropathy in DM2 patients. (authors)

    Full Text Available The current study analyzes the structure and some features of two urban metapopulations of the Balkan Wall Lizard (Podarcis tauricus (Pallas, 1814 from Nature Monument (NM “Mladezhki halm” and Nature Monument “Halm na osvoboditelite” in the city of Plovdiv (South Bulgaria. In both study sites, the Balkan Wall lizard inhabits exclusively the interior of the hills and prefers mainly open areas with rare grass and shrub vegetation. The recorded dominant plant species are not autochthonous for the hills, but gradually displaced with many decorative species, used widely in the gardening and thecity parks. The population abundance from both hills is relatively low, with higher values in NM “Mladezhki halm” and generally shows a decrease pattern for the two year period. In the hills of Plovdiv, the Balkan Wall lizard shows a bimodal diurnal and seasonal activity. Both metapopulations showed a sex ratio close to 1:1 with a slight superiority of the females (1:1.29, but with no statistically significant deviation. The age structure of both metapopulations is almost identical - the highest percentage takes the adults, followed by the subadults and juveniles, with no significant deviations from the normal ratio. The possible reasons for the contemporary distribution and population structure of the Balkan Wall lizard are discussed. Historic land use change and its effect on the populations are discussed as well. The main risks for this species in the city of Plovdiv are construction and forestation (destruction of open terrains. Nevertheless, the Balkan Wall lizard seems to have successfully overcome the risks of urbanization and its population seem stable and sustainable.

    A series of 13 cases of feline membranous nephropathy is presented. Two groups were distinguished clinically; eight cats had the nephrotic syndrome and five others were in renal failure but not nephrotic. The definitive diagnosis was based on histological, immunofluorescence and ultrastructural examinations of renal tissue obtained at renal biopsy or necropsy. Glomerular lesions were classified according to the degree of glomerular change into three distinct groups; mild, moderately severe and advanced. A relationship was established between the mild and moderately severe groups and cats with the nephrotic syndrome, and the advanced group and cats in renal failure. Diuretic therapy was satisfactory in initial control of oedema in the nephrotic cases. Monitoring of previously nephrotic cats for up to three years indicated that the disease is progressive, although in some cases it is sufficiently slow for a cat to live a relatively normal life without continuing treatment. The prognosis for cats presented in renal failure is hopeless. PMID:552741

    Chagas disease (CD) - a tropical parasitic disease caused by the protozoan Trypanosoma cruzi - is a major health problem in Latin America. The immune response against the parasite is responsible for chronic CD lesions. Currently, there are no reports of an association between CD and membranous nephropathy (MN). The detection of the phospholipase A2 receptor (PLA2R) as a target antigen in idiopathic MN can improve the differential diagnosis of primary and secondary forms of MN. The authors report the case of a male patient with positive serology for CD who presented sudden death and underwent autopsy. Histological sections of the heart showed multifocal inflammatory infiltrate composed mainly of mononuclear cells, leading to myocardiocytes necrosis and interstitial fibrosis. The kidneys showed a MN with positive expression for PLA2R. As far as we know, this is the first report of a case of primary MN in a patient with CD, with severe chronic cardiomyopathy and heart failure.

    Full Text Available Acute phosphate nephropathy is a form of acute kidney injury (AKI due to oral sodium phosphate (ONaP purgatives used for bowel cleansing before colonoscopy. Usually, 45 ml ONaP is given two times daily 12-24 hours prior to colonoscopy. Intestinal absorption is followed by transient hypocalcemia and hyperphosphatemia in almost all patients. In addition, severe hyperphosphatemia, symptomatic hypocalcemia, hypernatremia, hypocalcemia, hyponatremia, hypokalemia, high anion gap metabolic acidosis and AKI can be seen. The patient presented in this paper is a 65-year-old female. She was diagnosed with type 2 diabetes mellitus and hypertension. Colonoscopy was performed in order to investigate the etiology of iron deficiency anemia. ONaP was administered for preparation of colonoscopy and AKI which was clinically compatible with APN developed after the procedure.

    2013-01-01

    IgA nephropathy (IgAN) is the most common primary glomerular disease worldwide. About 25-30% of IgAN patients will progress to end-stage kidney disease in 20-25 years. Early-onset symptoms that are highly suggestive of progressive IgAN include massive proteinuria, hypertension, renal damage, glomerular sclerosis, crescent formation, and tubulointerstitial fibrosis. Progressive IgAN may progress to renal failure in a short time. Optimized supportive therapy is the fundamental treatment for progressive IgAN patients, and includes renin-angiotensin system blockers, blood pressure control, antiplatelet and anticoagulant drugs, statins, and allopurinol. In progressive IgAN patients whose clinical and pathological manifestations are more severe, active therapy may be considered including glucocorticoid therapy, cyclophosphamide, azathioprine, mycophenolate mofetil, tacrolimus, and other immunosuppressants. However, there are currently controversies on the definition and treatment of progressive IgAN. PMID:23689569

    IgA Nephropathy leads young people to dialysis more often than other glomerular diseases, because often diagnosis and therapy are made late. Nephrologists waive to treat IgAN pts with chronic renal insufficiency, believing that treatment may not be effective and safe. Moreover, studies in IgAN pts with reduced renal function are lacking. Small studies seem to indicate a possible utility of RAS blockers and corticosteroids in these patients. Recently, VALIGA study showed that corticosteroids and immunosuppressants were more frequently used in pts with eGFR 30 ml/min (60 vs. 44 %, respectively; p = 0.004). The goal of treating IgAN pts is to obtain a time-average proteinuria 1 g/day a 6-month course of corticosteroids could be useful and safe. PMID:26743078

    publications under the heading CIN have been published during the last 5 years. Fewer than 5% of these publications are randomized prospective controlled studies. In spite of the large number of reports on CIN, very little has been changed. The use of the smallest possible dose of low- or iso-osmolar contrast......Contrast-induced nephropathy (CIN) has been a hot topic during the last 5 years due its association with increased morbidity and mortality. CIN is an important complication, particularly in patients with advanced chronic kidney disease (CKD) associated with diabetes mellitus. Methods to diminish...... the incidence of CIN have been highly contentious. They include choice of contrast, pharmacologic manipulation, and volume expansion. The pathophysiology of this complication remains uncertain, but reduction in renal blood flow and direct toxicity of tubular cells has been implicated. More than 900...

    Objective: To investigate the role and mechanism of adrenomedullin (AM) in diabetic nephropathy. Methods:This research observed the changes of the expression and secretion of AM, TGF-β1 in the cultured human mesangial cells under high glucose conditions and the contents of the laminin and type Ⅳ collagen in the supernatants, and the effect of intervention with AM on the changes.Results: High glucose condition resulted in increase in the expression and secretion of AM, TGF-β1, laminin and type Ⅳ collagen, and AM could reverse the influence of high glucose on the cultured human mesangial cells. Conclusion: The results showed that high glucose condition in one of the stimulating factors of AM, and the renal protective action of AM may be associated with suppression of TGF-β1 and reducing excessive accumulation of laminin and type Ⅳ collagen.

  14. Effect of nephrotoxic drugs on the development of radiation nephropathy after bone marrow transplantation

    International Nuclear Information System (INIS)

    Chronic renal failure is a significant cause of late morbidity in bone marrow transplant patients whose conditioning regimen includes total body irradiation (TBI). Radiation is a major cause of this syndrome (bone marrow transplant nephropathy), but it may not be the only cause. These studies use a rat syngeneic bone marrow transplant model to determine whether nephrotoxic agents used in conjunction with bone marrow transplantation (BMT) could be enhancing or accelerating the development of radiation nephropathy. Rats received 11-17 Gy TBI in six fractions over 3 days followed by syngeneic bone marrow transplant. In conjunction with the bone marrow transplants, animals received either no drugs, cyclosporine, amphotericin, gentamicin, or busulfan. Drugs were given in schedules analogous to their use in clinical bone marrow transplantation. Drug doses were chosen so that the drug regimen alone caused detectable acute nephrotoxicity. Animals were followed for 6 months with periodic renal function tests. Gentamicin had no apparent interactions with TBI. Amphotericin increased the incidence of engraftment failure, but did not enhance radiation nephropathy. Cyclosporin with TBI caused late morbidity that appeared to be due to neurological problems, but did not enhance radiation nephropathy. Busulfan resulted in a significant enhancement of radiation nephropathy. Of the nephrotoxins used in conjunction with bone marrow transplantation only radiation and busulfan were found to be risk factors for bone marrow transplant nephropathy. 34 refs., 4 figs., 2 tabs

  15. Role of Nutrient-Sensing Signals in the Pathogenesis of Diabetic Nephropathy

    Full Text Available Diabetic nephropathy is the leading cause of end-stage renal disease worldwide. The multipronged drug approach still fails to fully prevent the onset and progression of diabetic nephropathy. Therefore, a new therapeutic target to improve the prognosis of diabetic nephropathy is urgently required. Nutrient-sensing signals and their related intracellular machinery have evolved to combat prolonged periods of starvation in mammals; and these systems are conserved in the kidney. Recent studies have suggested that the activity of three nutrient-sensing signals, mTORC1, AMPK, and Sirt1, is altered in the diabetic kidney. Furthermore, autophagy activity, which is regulated by the above-mentioned nutrient-sensing signals, is also altered in both podocytes and proximal tubular cells under diabetic conditions. Under diabetic conditions, an altered nutritional state owing to nutrient excess may disturb cellular homeostasis regulated by nutrient-responsible systems, leading to exacerbation of organelle dysfunction and diabetic nephropathy. In this review, we discuss new findings showing relationships between nutrient-sensing signals, autophagy, and diabetic nephropathy and suggest the therapeutic potential of nutrient-sensing signals in diabetic nephropathy.

    Background Contrast media administration can result in severe nephrotoxicity under pathological conditions such as diabetic nephropathy, congestive heart failure, dehydration, et al. The purpose of this study was to evaluate the effects of dietary hypercholesterolemia on contrast media-induced changes in renal function, blood flow, and histopathology.Methods Rats were fed either on a normal rodent diet (group N) or a high-cholesterol supplemented diet (group H; 4% cholesterol and 1% cholic acid) for 8 weeks. Half of the animals (n =6) from each diet group were then given a tail vein injection of 60% diatrizoate (6 ml/kg; group NC and group HC)and the other half were administered saline. Total serum cholesterol, triglyceride, serum creatinine,creatinine clearance rate, fractional excretion of sodium and potassium, and cortical nitric oxide production were determined one day following contrast media administration. Renal blood flow was determined by color Doppler flow imaging and pulsed-mode Doppler. Renal histopathology was observed by light microscopy.Results Total serum cholesterol and resistance indices of renal blood vessels increased significantly,while creatinine clearance rate and production of nitric oxide in the renal cortex decreased markedly in group HC and group H when compared to group N and group NC. The creatinine clearance rate decreased significantly in group HC compared to group H. Serum creatinine levels and fractional excretion of sodium and potassium in group HC were significantly higher than those in the other three groups. Severe tubular degeneration and necrosis, protein cast accumulation, and medullary congestion were found in group HC.Conclusion Hypercholesterolemia is a risk factor for contrast media-induced nephropathy.Hypercholesterolemia aggravates contrast media-induced nephrotoxicity through the reduced production of nitric oxide.

  17. Pathophysiology of radiocontrast nephropathy: a role for medullary hypoxia.

    Recent experimental data underlies the role of hypoxic tubular injury in the pathophysiology of radiocontrast nephropathy. Although systemic transient hypoxemia, increased blood viscosity, and a leftward shift of the oxygen-hemoglobin dissociation curve may all contribute to intrarenal hypoxia, imbalance between oxygen demand and supply plays a major role in radiocontrast-induced outer medullary hypoxic damage. Low oxygen tension normally exists in this renal region, reflecting the precarious regional oxygen supply and a high local metabolic rate and oxygen requirement, resulting from active salt reabsorption by medullary thick ascending limbs of Henle's loop. Radiologic contrast agents markedly aggravate outer medullary physiologic hypoxia. This results from enhanced metabolic activity and oxygen consumption (as a result of osmotic diuresis and increased salt delivery to the distal nephron) because the regional blood flow and the oxygen supply actually increase. The latter effect may result in part from the activation of various regulatory mediators of outer medullary blood flow to ensure maximal regional oxygen supply. Low-osmolar radiocontrast agents may be less nephrotoxic because of the smaller osmotic load and vasomotor alterations. Experimental radiocontrast-induced renal failure requires preconditioning of animals with various insults (for example, congestive heart failure, reduced renal mass, salt depletion, or inhibition of nitric oxide and prostaglandin synthesis). In all these perturbations, which resemble clinical conditions that predispose to contrast nephropathy, outer medullary hypoxic injury results from insufficiency or inactivation of mechanisms designed to preserve regional oxygen balance. This underlines the importance of identifying and ameliorating predisposing factors in the prevention of this iatrogenic disease. PMID:10548380

    2014-12-01

    Full Text Available Introduction: Contrast induced nephropathy (CIN is one of the complications of the use of intravascular contrast agents, being defined as a reduction of the glomerular filtration rate caused by the iodinated contrast. Most CIN data derive from the cardiovascular literature, which identified as the most consistent risk factors pre-existing chronic renal insufficiency and diabetes mellitus. However, these studies limit their conclusions to a more specific patient population. Computerized tomography as a cause of CIN has been studied less often. Objective: To report on the incidence of computerized tomography contrast induced nephropathy (CIN in an inpatient population of a tertiary general hospital, identifying potentially avoidable risk factors. Methods: We performed a prospective cohort study with inpatients admitted at a tertiary hospital requiring contrast-induced CT. The primary outcome was the development of CIN, measure by the alteration of serum creatinine or glomerular filtration rate in 48 or 72 hours. Through clinical interview, we verified possible risk factors and preventive measures instituted by the medical team and their association with development of CIN. Results: Of a total of 410 patients, 35 (8.5% developed CIN. There was a positive correlation between CIN and the presence of diabetes mellitus (OR = 2.15; 95%CI 1.35-4.06; p = 0.02, heart failure (OR = 2.23; 95%CI 1.18-8.8; p = 0.022, and renal failure (OR = 3.36; 95%CI 1.57- 7.17; p = 0.002 Conclusion: Incidence of CIN varies according to the population. Diabetes mellitus, heart failure and renal failure were independent risk factors for the development of CT-associated CIN. Further studies are needed to better understand and treat CT-associated CIN.

    Diabetic nephropathy (DN) is the leading cause of end-stage renal disease all over the world. India has a high incidence and prevalence of diabetes and >30% have nephropathy. Recently, a histological classification has been proposed. This study analyzed the renal histology in 114 diabetic patients with renal dysfunction. Nearly 75% of patients had DN. Fifty five (63.95%) were males. Mean duration of diabetes was 7.04 ± 4.9 years. Mean serum creatinine in study group was 5.2 ± 2.9 mg/dl, with mean estimated glomerular filtration rate of 23.43 ± 21.48 ml/min/1.732 m(2). Forty eight patients (55.81%) had diabetic retinopathy (DR); prevalence of DR was more in patients who had diabetes for > 10 years than patients who had diabetes for <6 years (P = 0.022). The most common histological class was Class IV observed in 37 (43.02. %) cases, Class III DN in 24 (27.90%) cases, Class IIa and Class IIb in 11 (12.79%) cases each and Class I DN in 3 (3.48%) cases. Higher histological class was associated with higher proteinuria, lower glomerular filtration rate (P < 0.001) and was more likely to be associated with retinopathy (P = 0.012) and hypertension (P = 0.0003) but did not correlate with duration of diabetes (P = 0.85). There was a poor correlation between retinopathy and DN. Biopsy helps to stage the renal lesions in diabetics with renal dysfunction.

    We have summarized the latest findings on markers for progression of immunoglobulin A (IgA) nephropathy (IgAN), the most common primary glomerulonephritis with a high prevalence among end-stage renal disease (ESRD) patients. The clinical predictors of renal outcome in IgAN nephropathy, such as proteinuria, hypertension, and decreased estimated glomerular filtration rate (eGFR) at the time of the diagnosis, are well known. The Oxford classification of IgAN identified four types of histological lesions (known as the MEST score) associated with the development of ESRD and/or a 50 % reduction in eGFR. In addition, the role of genetic risk factors associated with IgAN is being elucidated by genome-wide association studies, with multiple risk alleles described. Recently, biomarkers in serum (galactose-deficient IgA1, IgA/IgG autoantibodies against galactose-deficient IgA1, and soluble CD 89-IgA complexes) and urine (soluble transferrin receptor, interleukin-6/epidermal growth factor ratio, fractalkine, laminin G-like 3 peptide, κ light chains, and mannan-binding lectin) have been identified. Some of these biomarkers may represent candidates for the development of noninvasive diagnostic tests, that would be useful for detection of subclinical disease activity, monitoring disease progression, assessment of treatment, and at the same time circumventing the complications associated with renal biopsies. These advances, along with future disease-specific therapy, will be helpful in improving the treatment effectiveness, prognosis, and the quality of life in connection with IgAN. PMID:27142988

    The present paper analyzed 239 endemic genera in 67 families in the flora of seed plants in China.The results showed that there are five families containing more than ten endemic genera,namely,Gesneriaceae (27),which hereafter refers to the number of endemic genera in China,Composite (20),Labiatae (12),Cruciferae (11),and Umbelliferae (10),15 families with two endemic genera,and another 30 families with only one endemic genus.Four monotypic families (Ginkgoaceae,Davidiaceae,Eucommiaceae and Acanthochlamydaceae)are the most ancient,relict and characteristic in the flora of seed plants in China.Based on integrative data of systematics,fossil history,and morphological and molecular evidence of these genera,their origin,evolution and relationships were discussed.In gymnosperms,all endemic genera are relicts of the Arctic-Tertiary flora,having earlier evolutionary history,and can be traced back to the Cretaceous or to the Jurassic and even earlier.In angiosperms,the endemic genera are mostly relicts,and are represented in all lineages in the"Eight-Class System ofClassification of Angiosperms",and endemism can be found in almost every evolutionary stage of extant angiosperms.The relict genera once occupied huge areas in the northern hemisphere in the Tertiary or the late Cretaceous,while neo-endemism mostly originated in the late Tertiary.They came from Arctic-Tertiary,Paleo-tropical-Tertiary and Tethys-Tertiary florisitic elements,and the blend of the three elements with many genera of autochthonous origin.The endemism was formed when some dispersal routes such as the North Atlantic Land Bridge,and the Bering Bridge became discontinuous during the Tertiary,as well as the climate change and glaciations in the late Tertiary and the Quaternary.Therefore,the late Tertiary is the starting point of extant endemism of the flora in China.

    We planned the INNOVATION study to determine whether telmisartan, an angiotensin-2-receptor blocker, delays the progression of renal disease from incipient nephropathy to overt nephropathy in hypertensive or normotensive Japanese patients with type 2 diabetes mellitus. The INNOVATION study is a randomized, double-blind, placebo-controlled trial. Eligible patients must have incipient nephropathy (defined as a urinary albumin to creatinine ratio of 100-300 mg/g creatinine) and a serum creatinine concentration of 300 mg/g creatinine and 30% higher than the baseline on at least two consecutive visits). A total of 1855 patients have been enrolled from 160 study centres. In 527 randomized patients (28.4% of the enrolled patients), mean (SD) urinary albumin to creatinine ratio and serum creatinine concentration at baseline were 173.3 (47.2) mg/g creatinine and 0.78 (0.19) mg/dl. Sixty-eight per cent of the patients had hypertension at baseline. Mean (SD) systolic and diastolic blood pressures at baseline were 137.1 (14.6) and 77.5 (10.3) mmHg. The INNOVATION study will determine whether telmisartan, an angiotensin II receptor blocker, provides clinical benefits in hypertensive or normotensive patients with diabetes mellitus and diabetic nephropathy.

    Diabetic nephropathy is the leading cause of ESRD in high-income countries and a growing problem across the world. Vascular endothelial growth factor-A (VEGF-A) is thought to be a critical mediator of vascular dysfunction in diabetic nephropathy, yet VEGF-A knockout and overexpression of angiogenic VEGF-A isoforms each worsen diabetic nephropathy. We examined the vasculoprotective effects of the VEGF-A isoform VEGF-A165b in diabetic nephropathy. Renal expression of VEGF-A165b mRNA was upregulated in diabetic individuals with well preserved kidney function, but not in those with progressive disease. Reproducing this VEGF-A165b upregulation in mouse podocytes in vivo prevented functional and histologic abnormalities in diabetic nephropathy. Biweekly systemic injections of recombinant human VEGF-A165b reduced features of diabetic nephropathy when initiated during early or advanced nephropathy in a model of type 1 diabetes and when initiated during early nephropathy in a model of type 2 diabetes. VEGF-A165b normalized glomerular permeability through phosphorylation of VEGF receptor 2 in glomerular endothelial cells, and reversed diabetes-induced damage to the glomerular endothelial glycocalyx. VEGF-A165b also improved the permeability function of isolated diabetic human glomeruli. These results show that VEGF-A165b acts via the endothelium to protect blood vessels and ameliorate diabetic nephropathy. PMID:25542969

    researchers and scholars can find common grounds for discussion and collaboration (Hutchinson and Mindrescu, 2012.In this regard an international meeting was organized at the Geography Department, University of Suceava, Romania, and was cosponsored by the University of Suceava, the Applied Geography Association (GEOCONCEPT, Past Global Changes (PAGES and the Mountain Research Initiative (MRI. The purpose of the workshop was to bring together an international group of scientists interested in the Carpathian-Balkan region to discuss research results and promote opportunities for interdisciplinary and international collaboration. The entire workshop was webcast. The program centered on 36 oral and 15 poster presentations as well as open discussions on the climatic and environmental dynamics during the Pleistocene and Holocene. The 70 participants were from Romania, Hungary, Germany, United Kingdom, Bulgaria, Slovenia, Ukraine, Poland, Switzerland, Czech Republic, Greece and Belgium. For many young researchers and students the workshop offered an educational opportunity to present their results to an international audience and discuss their research in a multidisciplinary community.To promote follow-up activities in the region, the “Suceava working group” was created under the lead of Marcel Mindrescu, Angelica Feurdean, Eniko Magyari and Daniel Veres. A group website is currently being set up (http://atlas.usv.ro/www/climatechange/ and grant proposals will be prepared. The group will also coordinate the organization of a second regional workshop in 2014 in Romania. Further activities, such as summer camps or meetings in the field are also considered.

    Full Text Available A comparative analysis of selected short stories in the Balkan countries, as well as contemporary short stories of the world, will show us that the key themes of those stories are very similar to the short stories written during the period of transition in Bosnia and Herzegovina (1995-2010. For example, the story of the Soul Operation by an Iranian writer Mohsen Mahmalbafa, The Falcons by a Dutch writer Kader Abdolaha and On the Kitchen Stairs by a Polish writer Witold Gombrowic zinter connect with short stories by authors from Bosnia and Herzegovina, such as The Secret of Raspberry jam by Karim Zaimović or The Devilish work of Zoran Riđanović. A common thread manifests itself in the aforementioned stories, more specifically, a common theme which focuses on the need for eradication of the seeds of submission and compliance with the political system. Most authors focus on their domestic political systems; however, some portray and analyze systems in other countries as they see it, such as a Dutch narrator who focuses on a potential threat of infringement of human freedom. Moreover, Bellow Hubei by an Argentinian writer Anhelika Gorodis her underlines the importance of humanization within a political order. Faruk Šehić examines the political system in Bosnia and Herzegovina from a slightly different perspective. His collection of stories Under Pressure emphases the issue of pressure in the above war model of short stories in Bosnia and Herzegovina. These stories are the product of pressure and anxiety, with intent to latently promote new ways of spiritual survival, directly relating to the concept and the theme of the story The Past Age Man by Christian Karlson Stead. Further analysis of the alienation theme singled out short stories in Bosnia and Herzegovina, Plants are Something Else by Alma Lazarevska and Dialogues by Lamija Begagić, and pointed out their connection with some recent international short stories such as The Last Defence by

    Fasciolosis, caused by trematodes of the genus Fasciola, is an emerging disease of humans. One of the highest levels of human fasciolosis hepatica is found amongst the indigenous Aymaran people of the Northern Bolivian Altiplano. A meta-analysis of epidemiological surveys from 38 communities in the region demonstrates that fasciolosis has been endemic in the region since at least 1984 and is a zoonosis of rural communities. Human and bovine fasciolosis is associated with the communities lying in the plain from Lake Titicaca to La Paz, predominantly in the Los Andes province. In Los Andes incidences of up to 67% of population cohorts were found, and prevalence is age-related with the highest infection rate in children aged 8-11 years.

    Full Text Available In the face of progressing globalisation and liberalisation of the markets, innovation is the minimum necessary requirement for companies and countries to be globally competitive, and knowledge is the key input. In a comparative study we investigate the intellectual capital of a sample of firms from the Western Balkans and Slovenia, and analyse the link between intellectual capital, innovation, and export volume. Using unique survey data sets for these countries, we propose a structural model to examine our hypotheses. The results suggest that possessing intellectual capital does not suffice for firms’ global competitiveness and that higher presence on global markets may offer exposure to more advanced knowledge that firms cannot obtain in their domestic markets.

    L'objectif de ce numéro est de proposer une réflexion sur les conditions et les formes de politisation des enjeux identitaires dans les Balkans de Paprès-1989. Au premier chef, cette recherche est animée par l'exigence intellectuelle d'une « dés-exotisation » de la péninsule balkanique. Dans le sillage de l'éclatement de la Yougoslavie en 1991, l'Europe du Sud-Est a fait l'objet d'analyses accordant au registre identitaire une priorité, voire une exclusivité, dans l'élucidation des dynamiques...

    Comparison is made of the effectiveness on the steady state load flow control of the Phase Shifter and the Series Compensation. Attention is focused on the ability to reduce unscheduled loop flows and redirect power flows in the system. The Balkan section of UCPTE system resulting after the parallel synchronous interconnection of Bulgaria is used as test system with loading conditions corresponding to the 1995 peak load. The superior properties of PST on power flow control are shown. The positive effects of PST in maintaining a high level of steady state security while realizing relatively large multilateral power exchange programs are demonstrated. A comparison of the power flow control efficiencies and an economic estimate are made for PST and SC. 10 refs, 1 fig, 4 tabs

  10. Ash fell from the skies to the earth: The eruption of the Vesuvius in 1631 AD and the Balkan lands

    Full Text Available After the most notorious eruption of the Vesuvius in 79 AD, the one that occurred on 16th December 1631 resulted in thousands of human victims and large-scale damage. According to modern volcanology studies, the amount of dust and ash emitted on this occasion was only three times smaller that in the famous eruption of Krakatau in 1883. Numerous historical sources registered the fall of volcanic ash, which is proved to be the true meaning of three Serbian marginal notes presented in this article. Anonymous monks in the monasteries of St. George near Pljevlja, Pološko and another one which still cannot be precisely identified, reported the fallout of ash on Wednesday, December 7, according to the Julian, i.e. 17 according to the Gregorian calendar. Considering the velocity of ash clouds, it is assumed that in both cases it could have been the first thing they saw at dawn, on the day after the eruption (cf. the map in this paper. Along with the "black powder", the same kind of historical sources - Serbian marginal notes, and The Chronicle of Fra Nikola Lašvanin - also provide the data on "red/bloody snow" on three separate occasions (1638, 1640 and 1690. These phenomena can be scientifically explained as deposits of desert dust from northern Africa brought by south-southwest air currents over the Balkan region. The last issue discussed in this paper is the possible connection between this particular volcanic eruption and short-term climate changes it may have caused in the Balkans.

  11. Cultural cross-border co-operation among Balkan's countries with the case of Serbia and Bulgaria

    Full Text Available Cultural cross-border cooperation includes all fields of cross-border cooperation and gives base for main connections and interactions. Without strengthening cultural cross-border cooperation, it is impossible to build significant relations between neighbors. Culture, as a foundation, an activator and a purpose of development in cross-border regions, represents a cardinal and conditional factor of cross-border cooperation. Today's situation in the Balkans reveals ethnic diversity of this region and territorial dispersion of ethnic groups. This implies at the same time great cultural diversity as well as dispersal of various national cultures over the Balkan's states. During the 20th century Serbia and Bulgaria have very complex political and intrastate relations. But in the last 10 years there have been significant improvements in the cross-border cooperation between Serbia and Bulgaria. The results of these improvements are established Euro-regions and implemented cross-border projects between these two countries. Existing Euro-regions between Serbia and Bulgaria created links between various local authorities and made excellent basis for cross-border initiatives and joint projects to promote common interests across the border and cooperation for the common good of the border areas populations. The well managed cultural cross-border cooperation between these two countries will provide a clear view of common features and raise common identity for the region, contribute to tolerance and understanding between people in this area and enable them to overcome the peripheral status of the border region in their countries and improve the living conditions of the population.

    War experiences are associated with substantially increased rates of mental disorders, particularly Post-Traumatic Stress Disorder (PTSD) and Major Depression (MD). There is limited evidence on what type of war experiences have particularly strong associations with subsequent mental disorders. Our objective was to investigate the association of violations of human rights, as indicated in the 4th Geneva Convention, and other stressful war experiences with rates of PTSD and MD and symptom levels of intrusion, avoidance and hyperarousal. In 2005/6, human rights violations and other war experiences, PTSD, post-traumatic stress symptoms and MD were assessed in war affected community samples in five Balkan countries (Bosnia-Herzegovina, Croatia, Kosovo, Macedonia, and Serbia) and refugees in three Western European countries (Germany, Italy, United Kingdom). The main outcome measures were the MINI International Neuropsychiatric Interview and the Impact of Event Scale-Revised. In total 3313 participants in the Balkans and 854 refugees were assessed. Participants reported on average 2.3 rights violations and 2.3 other stressful war experiences. 22.8% of the participants were diagnosed with current PTSD and also 22.8% had MD. Most war experiences significantly increased the risk for both PTSD and MD. When the number of rights violations and other stressful experiences were considered in one model, both were significantly associated with higher risks for PTSD and were significantly associated with higher levels of intrusion, avoidance and hyperarousal. However, only the number of violations, and not of other stressful experiences, significantly increased the risk for MD. We conclude that different types of war experiences are associated with increased prevalence rates of PTSD and MD more than 5 years later. As compared to other stressful experiences, the experience of human rights violations similarly increases the risk of PTSD, but appears more important for MD.

  15. Endemic time-spaces of Finland: Aquatic regimes

    Directory of Open Access Journals (Sweden)

    Tero Mustonen

    2014-08-01

    Full Text Available This article explores the endemic time-spaces of Finnish aquatic regimes. More precisely, it examines the socio-ecological relationships between Finns and lakes, rivers, and marshes-mires. First, the 'engine' of endemic time-space research, land use, and occupancy documentation, is explored in the Finnish context. Then two catchment areas, Kokemäenjoki in Western Finland and Vuoksi in Eastern Finland, provide cases which illustrate both past endemic time-spaces and surviving aspects of cultural readings of lakes and rivers. The ongoing winter seining in Lake Puruvesi in North Karelia emerges as an unbroken practice, with deep roots, that maintains the endemic time-spaces of a traditional Finnish relationship with a lake. As industrial uses of catchment areas, zoning, and environmental permitting exclude endemic readings inherent on the land and waterscapes, solutions are explored through mapping, along with its limitations, as a form bridging the gap between local realities and resource extraction.

  16. Dynamic magnetic resonance imaging in the assessment of chronic medical nephropathies with impaired renal function

    2000-02-01

    We examined the value of dynamic magnetic resonance imaging (MRI) in chronic renal disease with renal insufficiency. In 33 consecutive patients (21 vascular nephropathy, 12 glomerular nephropathy) MRI was performed using a 1.5-T unit and a body coil, with SE T1-weighted (TR/TE = 600/19 ms) and dynamic TFFE T1-weighted sequences (TR/TE = 12/5 ms, flip angle = 25 ) after manual bolus injection (via a cubital vein) of 0.1 mmol/kg Gd-DTPA-BMA. Morphological evaluation was performed in unblinded fashion by three radiologists, evaluating renal size, cortical thickness, and corticomedullary differentiation. Functional analysis was performed by one reviewer. Time-signal intensity curves, peak intensity value (P), time to peak intensity (T), and the P/T ratio were obtained at the cortex, medulla, and pyelocaliceal system of each kidney. The relationship of these parameters to serum creatinine and with creatinine clearance was investigated. A good correlation between morphological features of the kidneys and serum creatinine values was found. Morphological findings could not distinguish between vascular and glomerular nephropathies. A statistically significant correlation (P <0.01) between cortical P, cortical P/T, medullary P, and serum creatinine and creatinine clearance was found. A significant correlation (P <0.01) was also found between cortical T, medullary P/T, T of the excretory system, and creatinine clearance. The cortical T value was significantly higher (P <0.01) in vascular nephropathy than in glomerular nephropathy. Thus in patients with chronic renal failure dynamic MRI shows both morphological and functional changes. Morphological changes are correlated with the degree of renal insufficiency and not with the type of nephropathy; the functional changes seem to differ in vascular from glomerular nephropathies.

    Full Text Available Abstract Background Contrast-induced nephropathy is the leading cause of in-hospital acute renal failure. This side effect of contrast agents leads to increased morbidity, mortality, and health costs. Ensuring adequate hydration prior to contrast exposure is highly effective at preventing this complication, although the optimal hydration strategy to prevent contrast-induced nephropathy still remains an unresolved issue. Former meta-analyses and several recent studies have shown conflicting results regarding the protective effect of sodium bicarbonate. The objective of this study was to assess the effectiveness of normal saline versus sodium bicarbonate for prevention of contrast-induced nephropathy. Methods The study searched MEDLINE, EMBASE, Cochrane databases, International Pharmaceutical Abstracts database, ISI Web of Science (until 15 December 2008, and conference proceedings for randomized controlled trials that compared normal saline with sodium bicarbonate-based hydration regimen regarding contrast-induced nephropathy. Random-effects models were used to calculate summary odds ratios. Results A total of 17 trials including 2,633 subjects were pooled. Pre-procedural hydration with sodium bicarbonate was associated with a significant decrease in the rate of contrast-induced nephropathy (odds ratios 0.52; 95% confidence interval 0.34–0.80, P = 0.003. Number needed to treat to prevent one case of contrast-induced nephropathy was 16 (95% confidence interval 10–34. No significant differences in the rates of post-procedure hemodialysis (P = 0.20 or death (P = 0.53 was observed. Conclusion Sodium bicarbonate-based hydration was found to be superior to normal saline in prevention of contrast-induced nephropathy in this updated meta-analysis.

    International Nuclear Information System (INIS)

    A Survey of goiter prevalence, among population of five endemic and four non endemic regions of Ethiopia was carried out prior to the distribution of iodate d salt. urine samples were collected from 327 subjects selected by systematic random sampling from endemic and 276 taken as non endemic. The lowest mean urinary iodine excretion (UIE) value was recorded in Bure (22 micro gl/day) and the highest in Alemmaya (148 micro gl/day). The highest goiter rate ( percent TGR) was recorded in Sawla 55.6 %) and the lowest (0.6 %) in Yabello. Iodine content of drinking was in the range of 0.4 - 48.5 micro gl. Iodine content of water source was correlated positively ( r0.8399) with the mean of UIE and TGR, however, indicates that sites considered as non endemic seem to be affected by iodine deficiency. The study results urge the need for intervention in controlling Iodine Deficiency Disorders. 3 tab

    Diabetes mellitus is a complex human disease that affects more than 280 million people worldwide. One of the diabetic long-term complications is diabetic nephropathy that it is responsible for 50% of all end-stage renal disease. The complexity of diabetes and the lack of comprehensive systematic studies have halted the development of drugs and clinical therapies for the treatment of diabetes and its major complications. The present project, based on the db/db mice as animal model, investigates the repercussions of diabetes mellitus in the transcriptome as well as the mechanism of action of pirfenidone, an antifibrotic drug, in the treatment of diabetic nephropathy. The study was centered on the system-wide measurements transcriptional state of the mouse kidney. The expression profile of three experimental groups: control, diabetic, and diabetic treated with the drug, were analyzed using expression clustering, gene ontology enrichment analysis, protein-protein interaction network mapping, and gene expression behavior. The results show significant expression dysregulation of genes involved in RNA processing, fatty acid oxidation, and oxidative phosphorylation under the diabetic condition. The drug is able to regulate the expression levels of RNA processing genes but it does not show any effect in the expression profile of genes required in the oxidative phosphorylation and in the fatty acid metabolism. In conclusion diabetes mellitus induce the dysregulation of the splicing apparatus, the oxidative phosphorylation, and the fatty acid metabolic pathway at an expression level. The malfunction of these biological pathways causes cellular stress by increasing the concentration of reactive oxygen species within the cell due to a high oxidative and respiratory activity of mitochondria in addition to the increased demand of the folding machinery as a consequence of a dysregulation of the splicing apparatus. Pirfenidone regulates the expression of RNA processing genes mainly

    Here we conducted a retrospective study to examine the risk of cardiovascular events (CVEs) relative to that of end-stage renal disease (ESRD) in patients with primary membranous nephropathy, in a discovery cohort of 404 patients. The cumulative incidence of CVEs was estimated in the setting of the competing risk of ESRD with risk factors for CVEs assessed by multivariable survival analysis. The observed cumulative incidences of CVEs were 4.4%, 5.4%, 8.2%, and 8.8% at 1, 2, 3, and 5 years respectively in the primary membranous nephropathy cohort. In the first 2 years after diagnosis, the risk for CVEs was similar to that of ESRD in the entire cohort, but exceeded it among patients with preserved renal function. Accounting for traditional risk factors and renal function, the severity of nephrosis at the time of the event (hazard ratio 2.1, 95% confidence interval 1.1 to 4.3) was a significant independent risk factor of CVEs. The incidence and risk factors of CVEs were affirmed in an external validation cohort of 557 patients with primary membranous nephropathy. Thus early in the course of disease, patients with primary membranous nephropathy have an increased risk of CVEs commensurate to, or exceeding that of ESRD. Hence, reduction of CVEs should be considered as a therapeutic outcome measure and focus of intervention in primary membranous nephropathy. PMID:26924046

    Full Text Available Diabetes and diabetic nephropathy are complex diseases affected by genetic and environmental factors. Identification of the susceptibility genes and investigation of their roles may provide useful information for better understanding of the pathogenesis and for developing novel therapeutic approaches. Intercellular adhesion molecule 1 (ICAM1 is a cell surface glycoprotein expressed on endothelial cells and leukocytes in the immune system. The ICAM1 gene is located on chromosome 19p13 within the linkage region of diabetes. In the recent years, accumulating reports have implicated that genetic polymorphisms in the ICAM1 gene are associated with diabetes and diabetic nephropathy. Serum ICAM1 levels in diabetes patients and the icam1 gene expression in kidney tissues of diabetic animals are increased compared to the controls. Therefore, ICAM1 may play a role in the development of diabetes and diabetic nephropathy. In this review, we present genomic structure, variation and regulation of the ICAM1 gene, summarized genetic and biological studies of this gene in diabetes and diabetic nephropathy and discussed about the potential application using ICAM1 as a biomarker and target for prediction and treatment of diabetes and diabetic nephropathy.

    Full Text Available Although recent studies have proven that renin-angiotensin system (RAS blockades retard the progression of diabetic nephropathy, the detailed mechanisms of their reno-protective effects on the development of diabetic nephropathy remain uncertain. In rodent models, it has been reported that reactive oxygen species (ROS are important for intrarenal angiotensinogen (AGT augmentation in the progression of diabetic nephropathy. However, no direct evidence is available to demonstrate that AGT expression is enhanced in the kidneys of patients with diabetes. To examine whether the expression levels of ROS- and RAS-related factors in kidneys are increased with the progression of diabetic nephropathy, biopsied samples from 8 controls and 27 patients with type 2 diabetes were used. After the biopsy, these patients were diagnosed with minor glomerular abnormality or diabetes mellitus by clinical and pathological findings. The intensities of AGT, angiotensin II (Ang II, 4-hydroxy-2-nonenal (4-HNE, and heme oxygenase-1 (HO-1 were examined by fluorescence in situ hybridization and/or immunohistochemistry. Expression levels were greater in patients with diabetes than in control subjects. Moreover, the augmented intrarenal AGT mRNA expression paralleled renal dysfunction in patients with diabetes. These data suggest the importance of the activated oxidative stress/AGT/RAS axis in the pathogenesis of diabetic nephropathy.

    Full Text Available The chronic type-2 diabetes mellitus leads to diabetic nephropathy, which is one of the major microvascular complication of end stage renal disease worldwide and causes premature death in diabetic patients. The objective of the present investigation was to evaluate the antidiabetic activity and protective effect of diabetic induced nephropathy of ethanolic extract of seeds of Eugenia jambolana (SEEJ by using in-vitro and in-vivo models. The in-vitro antidiabetic effect was studied by glucose uptake assay in lymphocyte culture preparation. The in-vivo antidiabetic activity and the effect on diabetic nephropathy was evaluated using streptozotocin-nicotinamide induced type-2 diabetes mellitus in male albino Wistar rats. The results of in-vitro study revealed that SEEJ increased the percentage glucose uptake when calculated in comparison with control group. The in-vivo study showed that blood glucose level was significantly reduced in dose dependent manner when compared to the diabetic control group. In addition, it significantly restored the body weight loss, increased kidney weight, glycosylated haemoglobin, blood urea, blood uric acid, blood urea nitrogen, blood creatinine, urine volume and urine microalbumin levels when compared to diabetic control groups. The report of histopathological study of rat kidney tissues strongly supported the protective effect of SEEJ in diabetic nephropathy. The findings of this investigation concluded that SEEJ has significant antidiabetic activity and potential protective effect in diabetic nephropathy.

    Full Text Available Endemism, the restriction of a taxon’s distribution to a specified geographical area, is central to the study of biogeography. Understanding endemism not only concerns a number of evolutionary and biogeographical issues, but also plays an important role in maintaining biodiversity and in the selection of priority areas for conservation. In recent years, various measures and analytical methods have been used to investigate patterns of endemism for various taxa from different regions. The emergence of these new measurements has benefited from the construction of phylogenetic trees and the implementation of data from spatial statistics. Some of these measures, such as phylogenetic diversity, phylogenetic endemism, and biogeographically weighted evolutionary distinctiveness deserve much more attention. Here, we review progress in the methodology used to measure the distribution patterns of endemism. These metrics have generally developed from a single time or space perspective to space-time united patterns. Specifically, the metrics include species richness, phylogenetic diversity and evolutionary distinctiveness, plus all there in combination as well as the weight of species range size. Moreover, we propose that studies on the distribution patterns of Chinese endemic taxa should pay attention to species diversity, phylogenetic diversity, species β-diversity, and phylogenetic β-diversity. In particular, model simulation analysis should be emphasized and implemented during investigations. These studies will provide fundamental knowledge for comprehensive recognition of scale-induced differences and for the detection of mechanisms underlying the distribution patterns of endemic taxa, and therefore provide theoretical support for biodiversity conservation.

    The risk of diabetic nephropathy is partially genetically determined. Diabetic nephropathy is linked to a gene locus on chromosome 18q22.3-q23. We aimed to identify the causative gene on chromosome 18 and to study the mechanism by which the product of this gene could be involved in the development of diabetic nephropathy. DNA polymorphisms were determined in 135 case (diabetic nephropathy) and 107 control (diabetes without nephropathy) subjects. The effect of carnosine on the production of extracellular matrix components and transforming growth factor-beta (TGF-beta) after exposure to 5 and 25 mmol/l d-glucose was studied in cultured human podocytes and mesangial cells, respectively. A trinucleotide repeat in exon 2 of the CNDP1 gene, coding for a leucine repeat in the leader peptide of the carnosinase-1 precursor, was associated with nephropathy. The shortest allelic form (CNDP1 Mannheim) was more common in the absence of nephropathy (P = 0.0028, odds ratio 2.56 [95% CI 1.36-4.84]) and was associated with lower serum carnosinase levels. Carnosine inhibited the increased production of fibronectin and collagen type VI in podocytes and the increased production of TGF-beta in mesangial cells induced by 25 mmol/l glucose. Diabetic patients with the CNDP1 Mannheim variant are less susceptible for nephropathy. Carnosine protects against the adverse effects of high glucose levels on renal cells. PMID:16046297

  11. REVIEW: Endemic plants of serpentine soils

    Directory of Open Access Journals (Sweden)

    SUDARMONO

    2007-10-01

    Full Text Available Plant adaptation to serpentine soils is a system ideal for studies in evolutionary ecology. Serpentine soils are characterized by low calcium to magnesium ratios with Ca at significantly lower concentrations relative to surrounding areas. Although some variation occurs between sites which identified three collective traits: poor plant productivity, high rates of endemism and vegetation type distinct from those of neighboring areas. The several morphological feature characteristic of serpentine-tolerant species is possess xeromorphic foliage, including reduced leaf size and sclerophylls, the stature is significantly reduced relative to counterparts on non serpentine soil and root systems of species growing on and off serpentine sites are often more developed on serpentine soils than on neighboring soils. Serpentine soils are ubiquitous, but patchily distributed and thus promote geographic isolation. Adaptation to edaphic conditions may also beget reproductive isolation. Adaptive mutation might be influenced frequently from related species inhabiting surrounding areas. For the future studies involving serpentine systems merge the fields of ecology, evolution, physiology, and genetics required for serpentine adaptation.

    The demographic characteristics of an amphibian population fluctuate independently over time, mainly in response to the temporal variation of environmental factors, especially precipitation and temperature. These temporal fluctuations may contribute to the size of an amphibian population and could be used to determine the current conservation status of a species. During a five year (2004-2008) period, we studied the relative abundance, sex ratio, and age-sex structure of a population of metamorphosed individuals of the endemic treefrog Hyla eximia in Central Mexico. We also studied the species' relationship with climatic variables such as temperature and precipitation. We found an interannual constant abundance during the study period. However, interannual differences were observed in the population structure by age-sex category (males, females, or juveniles), with decreased abundance of males and juveniles during the rainy months (August-November). The annual abundance of H. eximia was positively correlated with rainfall, but negatively with monthly temperature. We found the sex ratio was male-biased (2:1), except for year 2008. Also, differences in snout-vent length (SVL) were found between years, suggesting changes in recruitment of new individuals. We conclude that variations in abundance, and frequencies by age-sex category, of H. eximia are related to seasonal variations in temperature and precipitation characteristics of temperate zones. However, this temporal stability may suggest that anurans have an unusual capacity to persist even in the face of human-induced habitat change. PMID:26421242

    Full Text Available Nine new microsatellite markers (SSR were isolated from Salvia officinalis L. A total of 125 alleles, with 8 to 21 alleles per locus, were detected in a natural population from the east Adriatic coast. The observed heterozygosity, expected heterozygosity, and polymorphic information content ranged from 0.46 to 0.83, 0.73 to 0.93 and 0.70 to 0.92, respectively. New microsatellite markers, as well as previously published markers, were tested for cross-amplification in Salvia brachyodon Vandas, a narrow endemic species known to be present in only two localities on the Balkan Peninsula. Out of 30 microsatellite markers tested on the natural S. brachyodon population, 15 were successfully amplified. To obtain evidence of recent bottleneck events in the populations of both species, observed genetic diversity (HE was compared to the expected genetic diversity at mutation-drift equilibrium (HEQ and calculated from the observed number of alleles using a two-phased mutation model (TPM. Recent bottleneck events were detected only in the S. brachyodon population. This result suggests the need to reconsider the current threat category of this endemic species.

    Objective. Adropin is a newly identified regulatory protein encoded by the Enho gene and is critically involved in energy homeostasis and insulin sensitivity. This study aims to determine the correlation of serum adropin concentrations with diabetic nephropathy (DN). Methods. This study consisted of 245 patients with type 2 diabetes mellitus (T2DM) and 81 healthy subjects. Then T2DM patients were divided into normoalbuminuria, microalbuminuria, and macroalbuminuria subgroups based on urine albumin to creatinine ratio (ACR). Results. T2DM patients showed significantly lower serum adropin concentrations than those in the controls. T2DM patients with macroalbuminuria had significantly decreased serum adropin concentrations compared with the other three groups. In addition, T2DM patients with microalbuminuria showed lower serum adropin concentrations than those in patients with normoalbuminuria. Logistic regression analysis showed that serum adropin was correlated with decreased risk of developing T2DM and DN. Pearson correlation analysis indicated that serum adropin was negatively correlated with body mass index (BMI), blood urea nitrogen, creatinine, and ACR and positively correlated with glomerular filtration rate. Furthermore, multiple linear regression analysis showed that BMI and ACR were negatively correlated with serum adropin levels. Conclusion. Serum adropin concentrations are negatively associated with renal function. Adropin may be implicated in the pathogenesis of DN development. PMID:27546995

    Diabetic nephropathy (DN) is a frequent and severe complication of diabetes mellitus (DM). Its diagnosis in incipient stages may allow prompt interventions and an improved prognosis. Towards this aim, biomarkers for detecting early DN can be used. Microalbuminuria has been proven a remarkably useful biomarker, being used for diagnosis of DN, for assessing its associated condition—mainly cardiovascular ones—and for monitoring its progression. New researches are pointing that some of these biomarkers (i.e., glomerular, tubular, inflammation markers, and biomarkers of oxidative stress) precede albuminuria in some patients. However, their usefulness is widely debated in the literature and has not yet led to the validation of a new “gold standard” biomarker for the early diagnosis of DN. Currently, microalbuminuria is an important biomarker for both glomerular and tubular injury. Other glomerular biomarkers (transferrin and ceruloplasmin) are under evaluation. Tubular biomarkers in DN seem to be of a paramount importance in the early diagnosis of DN since tubular lesions occur early. Additionally, biomarkers of inflammation, oxidative stress, podocyte biomarkers, and vascular biomarkers have been employed for assessing early DN. The purpose of this review is to provide an overview of the current biomarkers used for the diagnosis of early DN.

  16. Risk score for contrast induced nephropathy following percutaneous coronary intervention

    International Nuclear Information System (INIS)

    Contrast-induced nephropathy (CIN) is an important cause of acute renal failure. Identification of risk factors of CIN and creating a simple risk scoring for CIN after percutaneous coronary intervention (PCI) is important. A prospective single center study was conducted in Kuwait chest disease hospital. All patients admitted to chest disease hospital for PCI from March to May 2005 were included in the study. Total of 247 patients were randomly assigned for the development dataset and 100 for the validation set using the simple random method. The overall occurrence of CIN in the development set was 5.52%. Using multivariate analysis; basal Serum creatinine, shock, female gender, multivessel PCI, and diabetes mellitus were identified as risk factors. Scores assigned to different variables yielded basal creatinine > 115 micron mol/L with the highest score(7), followed by shock (3), female gender, multivessel PCI and diabetes mellitus had the same score (2). Patients were further risk stratified into low risk score (12). The developed CIN model demonstrated good discriminative power in the validation population. In conclusion, use of a simple risk score for CIN can predict the probability of CIN after PCI; this however needs further validation in larger multicenter trials. (author)

    Despite improvements in glycaemic and blood pressure control, and the efficacy of renin-angiotensin system (RAS) blockade for proteinuria reduction, diabetic nephropathy is the most frequent cause of end-stage renal disease in developed countries. This finding is consistent with the hypothesis that key pathogenetic mechanisms leading to progression of renal disease are not modified or inactivated by current therapeutic approaches. Although extensive research has elucidated molecular signalling mechanisms that are involved in progression of diabetic kidney disease, a number of high-profile clinical trials of potentially nephroprotective agents have failed, highlighting an insufficient understanding of pathogenic pathways. These include trials of paricalcitol in early diabetic kidney disease and bardoxolone methyl in advanced-stage disease. Various strategies based on encouraging data from preclinical studies that showed renoprotective effects of receptor antagonists, neutralizing antibodies, kinase inhibitors, small compounds and peptide-based technologies are currently been tested in randomized controlled trials. Phase II clinical trials are investigating approaches targeting inflammation, fibrosis and signalling pathways. However, only one trial that aims to provide evidence for marketing approval of a potentially renoprotective drug (atrasentan) is underway-further research into the potential nephroprotective effects of novel glucose-lowering agents is required.

    Abstract The association between membranous nephropathy (MN) and immunological disorder-related liver disease has not been extensively investigated, and the specific features of this uncommon association, if any, remain to be determined. We retrospectively identified 10 patients with this association. We aimed to describe the clinical, biological, and pathological characteristics of these patients and their therapeutic management. The possible involvement of the phospholipase A2 receptor (PLA2R) in these apparent secondary forms of MN was assessed by immunohistochemistry with renal and liver biopsy specimens. The mean delay between MN and liver disease diagnoses was 3.9 years and the interval between the diagnosis of the glomerular and liver diseases was PLA2R antibodies were detected in 4 out of 9 patients but the test was performed under specific immunosuppressive treatment in 3 out of 9 patients. Seven of the 9 patients with available renal tissue specimens displayed enhanced expression of PLA2R in glomeruli whereas PLA2R was not expressed in liver parenchyma from these patients or in normal liver tissue. The study of immunoglobulin (Ig) subclasses of deposits in glomeruli revealed that the most frequent pattern was the coexistence of IgG1 and IgG4 immune deposits with IgG4 predominating. Detection of PLA2R antibodies in glomeruli but not in liver parenchyma is a common finding in patients with MN associated with autoimmune liver disease, suggesting that these autoantibodies are not exclusively detected in idiopathic MN.

    The M-type phospholipase A2 receptor (PLA2R) is a target autoantigen in adult idiopathic membranous nephropathy (MN), but the prevalence of autoantibodies against PLA2R is unknown among Chinese patients with MN. Here, we measured anti-PLA2R antibody in the serum of 60 patients with idiopathic MN, 20 with lupus-associated MN, 16 with hepatitis B (HBV)-associated MN, and 10 with tumor-associated MN. Among patients with idiopathic MN, 49 (82%) had detectable anti-PLA2R autoantibodies using a Western blot assay; an assay with greater sensitivity detected very low titers of anti-PLA2R in 10 of the remaining 11 patients. Using the standard assay, we detected anti-PLA2R antibody in only 1 patient with lupus, 1 with HBV, and 3 with cancer, producing an overall specificity of 89% in this cohort limited to patients with secondary MN. The enhanced assay detected low titers of anti-PLA2R in only 2 additional samples of HBV-associated MN. In summary, these results suggest that PLA2R is a major target antigen in Chinese idiopathic MN and that detection of anti-PLA2R is a sensitive test for idiopathic MN.

    Reactive oxygen species (ROS) contribute to the development of interstitial fibrosis and tubular atrophy seen in chronic allograft nephropathy (CAN). As molecular hydrogen gas can act as a scavenger of ROS, we tested the effect of treatment with hydrogen water (HW) in a model of kidney transplantation, in which allografts from Lewis rats were orthotopically transplanted into Brown Norway recipients that had undergone bilateral nephrectomy. Molecular hydrogen was dissolved in water and recipients were given HW from day 0 until day 150. Rats that were treated with regular water (RW) gradually developed proteinuria and their creatinine clearance declined, ultimately leading to graft failure secondary to CAN. In contrast, treatment with HW improved allograft function, slowed the progression of CAN, reduced oxidant injury and inflammatory mediator production, and improved overall survival. Inflammatory signaling pathways, such as mitogen-activated protein kinases, were less activated in renal allografts from HW-treated rats as compared with RW-treated rats. Hence, oral HW is an effective antioxidant and antiinflammatory agent that prevented CAN, improved survival of rat renal allografts, and may be of therapeutic value in the setting of transplantation.

    2016-03-01

    Recent estimates suggest that 1 in 12 of the global population suffers from diabetes mellitus. Approximately 40 % of those affected will go on to develop diabetes-related chronic kidney disease or diabetic nephropathy (DN). DN is a major cause of disability and premature death. Existing tests for prognostic purposes are limited and can be invasive, and interventions to delay progression are challenging. MicroRNAs (miRNAs) are a recently described class of molecular regulators found ubiquitously in human tissues and bodily fluids, where they are highly stable. Alterations in miRNA expression profiles have been observed in numerous diseases. Blood and tissue miRNAs are already established cancer biomarkers, and cardiovascular, metabolic and immune disease miRNA biomarkers are under development. Urinary miRNAs represent a potential novel source of non-invasive biomarkers for kidney diseases, including DN. In addition, recent data suggest that miRNAs may have therapeutic applications. Here, we review the utility of miRNAs as biomarkers for the early detection and progression of DN, assess emerging data on miRNAs implicated in DN pathology and discuss how the data from both fields may contribute to the development of novel therapeutic agents.

    Full Text Available Knowledge of the pathophysiology of immunoglobulin A nephropathy (IgAN has progressed significantly, with this disease being clearly identified as an autoimmune disease with a peculiar autoantigen (galactosedeficient IgA1 [Gd-IgA1], specific autoantibodies (IgG and IgA1 anti-glycans, and formation followed by mesangial deposition of circulating immune complexes with the involvement of other players, such as mesangial transferrin receptor (TfR, monocyte Fcα receptor (CD89, and glomerular transglutaminase 2 (TG2. The pathogenesis still requires additional clarifications in order to explain the initiation of the disease and to establish the respective role of genetics, environment, and hazard concordance in the cascade of events/steps. The clinical application of this new knowledge is spreading slowly and includes possible measurement of serum Gd-IgA1, IgG anti-Gd-IgA1, IgA anti-Gd-IgA1, soluble CD89, and soluble TfR in the urine of patients with IgAN.

    Aristolochic acid (AA) is a compound extracted from the Aristolochia species of herbs. It has been used for centuries as a remedy for various illnesses and diseases. However, in the early 1990s in the setting of a weight loss herbal remedy, AA exposure was associated with a syndrome of kidney injury, termed aristolochic acid nephropathy (AAN). This entity is marked by elevated serum creatinine, significant anemia, and histopathologic changes demonstrating a hypocellular interstitial infiltrate with severe fibrosis. Progression towards end-stage renal disease (ESRD) is rapid, with most patients having chronic kidney disease for less than 2 years. In addition, AAN is associated with a 40-45 % prevalence of urothelial carcinomas. Treatment of AAN is limited to glucocorticoids that have been shown to delay progression in non-randomized trials. As most patients progress to ESRD, need for renal replacement therapy, as either dialysis or kidney transplant, usually ensues. However, given the high malignant potential, care must be taken to minimize future development of upper urinary tract cancers by performing prophylactic bilateral nephroureterectomies and aggressive cancer surveillance.

    2016-09-01

    Congenital obstructive nephropathy (CON) is the leading cause of chronic kidney disease (CKD) in children. Anomalies of the urinary tract are often associated with abnormal nephrogenesis, which is compounded by obstructive injury and by maternal risk factors associated with low birth weight. Currently available fetal and postnatal imaging and analytes of amniotic fluid, urine, or blood lack predictive value. For ureteropelvic junction obstruction, biomarkers are needed for optimal timing of pyeloplasty; for posterior urethral valves, biomarkers of long-term prognosis and CKD are needed. The initial nephron number may be a major determinant of progression of CKD, and most patients with CON who progress to renal failure reach this point in adulthood, presumably compounded by episodes of acute kidney injury. Biomarkers of tubular injury may be of particular value in predicting the need for surgical intervention or in tracking progression of CKD, and must be adjusted for patient age. Discovery of new biomarkers may depend on "unbiased" proteomics, whereby patterns of urinary peptide fragments from patients with CON are analyzed in comparison to controls. Most promising are the analysis of urinary exosomes (restricting biomarkers to relevant tubular cells) and quantitative magnetic resonance imaging techniques allowing precise determination of nephron number and tubular mass. The greatest need is for large prospective multicenter studies with centralized biomarker sample repositories to follow patients with CON from fetal life through adulthood. PMID:26667236

    Diabetic nephropathy (DN) is the leading cause of end-stage kidney disease worldwide but current treatments remain suboptimal. The role of inflammation in DN has only recently been recognized. It has been shown that the NLRP3-inflammasome contributes to DN development by inducing interleukin (IL)-1β processing and secretion. In an effort to understand other IL-1β activating mechanism during DN development, we examined the role of the NLRC4-inflammasome in DN and found that NLRC4 is a parallel mechanism, in addition to the NLRP3-inflammasome, to induce pro-IL-1β processing and activation. We found that the expression of NLRC4 is elevated in DN kidneys. NLRC4-deficiency results in diminished DN disease progression, as manifested by a decrease in blood glucose and albumin excretion, as well as preserved renal histology. We further found that DN kidneys have increased F4/80+ macrophages, increased IL-1β production, and other signaling pathways related to kidney pathology such as activation of NF-κB and MAP kinase pathways, all of which were rescued by NLRC4-deficiency. This study demonstrates NLRC4-driven IL-1β production as critical for the progression of DN, which underscores the importance to target this pathway to alleviate this devastating disease.

    Objective To investigate the role of P-selectin in IgA nephropathy (IgAN). Methods Plasma P-selectin level was measured by ELISA and P-selectin expression in renal tissue was detected by immunohistochemistry and in situ hybridization in 45 patients with IgAN. Results Plasma P-selectin levels in the patients with IgAN were significantly higher than those in the controls. In IgAN, the levels in the patients with nephrotic syndrome or renal function insufficiency were much higher than those in the patients with gross hematuria, abnormal urine analyses or nephritis syndrome. P- selectin was widely expressed within renal tissue in IgAN. Glomerular P- selectin expression was remarkably up - regulated in grade Ⅳ and Ⅴ of IgAN than that in grade Ⅱ and Ⅲ. Moreover, the expression of P- selectin on tubular epithelium or within interstitium was strongly associated with the degree of tubulointerstitial lesions. Conclusion The results suggested that P- selectin might play an important role in IgAN, and the level of P - selectin in plasma and renal tissue might predict the progress of IgAN.

    Full Text Available Tissue hypoxia/ischemia is a pathological feature of many human disorders including stroke, myocardial infarction, hypoxic/ischemic nephropathy, as well as cancer. In the kidney, the combination of limited oxygen supply to the tissues and high oxygen demand is considered the main reason for the susceptibility of the kidney to hypoxic/ischemic injury. In recent years, increasing evidence has indicated that a reduction in renal oxygen tension/blood supply plays an important role in acute kidney injury, chronic kidney disease, and renal tumorigenesis. However, the underlying signaling mechanisms, whereby hypoxia alters cellular behaviors, remain poorly understood. Mitogen-activated protein kinases (MAPKs are key signal-transducing enzymes activated by a wide range of extracellular stimuli, including hypoxia/ischemia. There are four major family members of MAPKs: the extracellular signal-regulated kinases-1 and -2 (ERK1/2, the c-Jun N-terminal kinases (JNK, p38 MAPKs, and extracellular signal-regulated kinase-5 (ERK5/BMK1. Recent studies, including ours, suggest that these MAPKs are differentially involved in renal responses to hypoxic/ischemic stress. This review will discuss their changes in hypoxic/ischemic pathophysiology with acute kidney injury, chronic kidney diseases and renal carcinoma.

    Diabetic nephropathy (DN) is a common and serious complication of diabetes associated with adverse outcomes of renal failure, cardiovascular disease, and premature mortality. Early and accurate identification of DN is therefore of critical importance to improve patient outcomes. Albuminuria, a marker of glomerular involvement in early renal damage, cannot always detect early DN. Thus, more sensitive and specific markers in addition to albuminuria are needed to predict the early onset and progression of DN. Tubular injury, as shown by the detection of tubular injury markers in the urine, is a critical component of the early course of DN. These urinary tubular markers may increase in diabetic patients, even before diagnosis of microalbuminuria representing early markers of normoalbuminuric DN. In this review we summarized some new and important urinary markers of tubular injury, such as neutrophil gelatinase associated lipocalin (NGAL), kidney injury molecule-1 (KIM-1), liver-type fatty acid binding protein (L-FABP), N-acetyl-beta-glucosaminidase (NAG), alpha-1 microglobulin (A1M), beta 2-microglobulin (B2-M), and retinol binding protein (RBP) associated with early DN.

    2016-07-01

    Lessons from an animal model that faithfully resembles human membranous nephropathy (MN) have informed our understanding of the pathogenesis of this organ-specific autoimmune disease and common cause of nephrotic syndrome. After it was established that the subepithelial immune deposits that characterize experimental MN form in situ when circulating antibodies bind to an intrinsic podocyte antigen, it was merely a matter of time before the human antigen was identified. The M-type phospholipase A2 receptor 1 (PLA2R) represents the major target antigen in primary MN, and thrombospondin type 1 domain-containing 7A (THSD7A) was more recently identified as a minor antigen. Serologic tests for anti-PLA2R and kidney biopsy specimen staining for PLA2R show >90% specificity and 70% to 80% sensitivity for the diagnosis of primary MN in most populations. The assays distinguish most cases of primary MN from MN associated with other systemic diseases, and sequential anti-PLA2R titers are useful to monitor treatment response. A positive pretransplantation test result for anti-PLA2R is also helpful for predicting the risk for posttransplantation recurrence. Identification of target epitopes within PLA2R and the genetic association of primary MN with class II major histocompatibility and PLA2R1 variants are 2 additional examples of our evolving understanding of this disease.

    A 15-year-old boy with a posterior urethral valve received a deceased donor kidney transplant (KT) in March 2011. Basiliximab induction followed by tacrolimus-based triple medication was used as immunosuppression. Eleven months after KT, the graft function deteriorated and the biopsy demonstrated interstitial nephritis suggestive of acute rejection. BK polyomavirus (BKPyV) surveillance in urine and plasma was negative. The patient received methylprednisolone pulses and anti-thymocyte globulin. Immunohistochemistry was positive for simian virus 40 (SV40) large T-antigen (LTag) in the biopsies, and quantitative polymerase chain reaction for JC polyomavirus (JCPyV) indicated high viral loads in urine and borderline levels in plasma. Immunosuppression was reduced and follow-up biopsies showed tubular atrophy and interstitial fibrosis. Two years after KT, antibody-mediated rejection resulted in graft loss and return to hemodialysis. Retrospective serologic work-up indicated a primary JCPyV infection with seroconversion first for IgM, followed by IgG, but no indication of BKPyV infection. In the SV40 LTag positive biopsies, JCPyV deoxyribonucleic acid (DNA) with archetype noncoding control region was detected, while BKPyV DNA was undetectable. To the best of our knowledge, this is the first reported case of primary JCPyV infection as the cause of PyV-associated nephropathy in KT. PMID:25359127

From Lake Ohrid, several sediment cores up to 15m long have been studied over the last few years. Here, we document the first long sediment record from nearby Lake Prespa to clarify the influence of Lake Prespa on Lake Ohrid and the environmental history of the region. Radiocarbon dating and dated te...

    Full Text Available The paper examines the meanings of representations of Serbia, the Balkans and Europe at the time of encounter between Enlightenment and Romanticist traditions. The analysis starts from the assumption that the emergence of negative representations of South Eastern Europe cannot be discussed without placing it within the broader context of 18th and 19th century philosophy and literature and the consequences of new philosophical and literary ideas. Underlying the substantial change of the previously dominant paradigms that is expressed in the symbolic division into 'West' and "East', there was a factual rather than symbolic division into an industrial and an agricultural Europe, whose boundaries coincided with the reference points of the symbolic distinction. Insisting on the importance of both analytic levels - the 'symbolic' and the 'factual' - the first section of the paper briefly outlines the development of symbolic geography in the context of 'Balkan' studies ('Balkan variations of orientalism' or 'balkanism' in the 1990s, as well as the failure of this genre and the constructivist paradigm in Serbian social theory. The second section is devoted to the discourses of conceptualizing broader communities in symbolic, linguistic, imagological, cultural, political, economic etc. terms, focusing on the beginnings of ideological and linguistic unification of South Slavs and their inclusion into the "enlightened Europe". By analyzing Vuk Stefanovia: Karadzix's writings, as well as correspondence, articles and commentaries referring to Vuk's work in the first half of the 19th century, the author takes the perspective of the past in order to identify the reasons for the failure of imagological and constructivist approach today.

    The first spread of farming practices into Europe in the Neolithic period involves two distinct ‘streams’, respectively around the Mediterranean littoral and along the Danube corridor to central Europe. In this paper we explore variation in Neolithic animal use practices within and between these streams, focusing on the first region in which they are clearly distinct (and yet still in close proximity): the western Balkans. We employ rigorous and reproducible meta-analysis of all available zoo...

    The effects of spirapril and isradipine on blood pressure, urinary albumin excretion and sodium-volume homeostasis in hypertensive insulin-dependent diabetic patients with nephropathy were assessed. Fifteen Type 1 diabetic patients aged 28-53 years with a diabetes duration of 19-37 years were...... studied. All had hypertension and diabetic nephropathy with a urinary albumin excretion of more than 300 mg/24 h. After a single blind placebo treatment period of 4 weeks the patients were randomly assigned to treatment with the calcium antagonist isradipine SRO 5 mg once daily or the ACE inhibitor...... vs 2636 +/- 194 meq/1.73 m2 (p treatment these parameters remained unchanged. In conclusion both isradipine and spirapril lowered blood pressure in patients with diabetic nephropathy. Only the ACE inhibitor had demonstrable...
