The holotype is deposited in the EMNH (Estonian Museum of Natural History’s) collection, Tallinn, Estonia. The paratypes are deposited in the Estonian Museum of Natural History’s collection, in the private collection of A. Lindt, and in the IZBE insect collection housed in the Estonian University of Life Sciences. Diagnosis. Wings semi-transparent, plain green with fine brownish strigulation and a thin white marginal line; blotches absent. Slender valva, with a long, apically bulbed and spiculose appendage; sternite A 8 with two triangular, pointed projections to its posterior edge. Description. Moths (Fig. A): Wingspan, males 19–22 mm, females 25–26 mm. Head: The palpi are brown, projecting before the frons; the frons is brown below and dark brown above; the interantennal fillet is white with scattered red-brown scales; and the vertex is green with a reddish-brown line between. The antennae in both sexes are pectinated, antennal shaft is light brown. Diameter of the shaft is 0.2 mm; the length of internal and external rami at the tenth antennal segment in the male is 0.75 mm and 1.0 mm, and in the female 0.5 mm and 0.65 mm, respectively. Thorax and abdomen: The thorax and abdomen are green, abdominal tergites 1–5 bear large dark brown crests which are ringed with white and inlaid by some long white hairscales. The male hind legs are slender, without a hair pencil and with one (distal) pair of spurs. The wings are light green, with some long green hairscales embedded between flat scales, being less numerous in the hindwings, and sparsely striated transversely with brown. The costal edge of the forewing is lined in light brown, and the marginal line is blackish on both wings, accompanied by a white line which is thicker on veins and edged proximally by sparse rose and dark scales. The fringe is white and rosy. The distal margin of forewings is slightly convex, and that of hindwings evenly rounded, but in some females it is slightly elbowed at vein M 3. The forewings have small dark discal spots; the hindwings have pairs of a tiny dark and a small oblong white discal spot. FIGURES A–C. A. Oospila bulava, sp. nov., male. B. Oospila bulava, sp. nov., male genital capsule, aedeagus and sternite A 8. C. Oospila bulava, sp. nov., female genitalia. Male genitalia (Fig. B): The uncus is reduced, the socii are large, roundish oblong, and the gnathi short, hooked and pointed. The tegumen is squarish, and as long as the V-shaped vinculum. The anellar complex is fused with the dorsal margin of transtilla. The juxta is short, with the bases of sacculi touching between the juxta and the saccus. The valva is slender, and the sacculus has an apical, pointed process lacking but two small roundish projections between the saccular lobe and ventral edge of the valvula present instead. There is a long, stout, apically clubbed appendage arising from the base of the valva near costa, being a little longer than the valvula. The ventral margin of the valvula and the distal half of the sacculus are roughly setose. The distal end of the aedeagus is cut truncate and has one cornutus on a long, folded vesica. The posterior margin of the sternite A 8 has two broad, triangular projections separated by a sharp, V-shaped medial excision; the edges of this excision are sclerotized. Female genitalia (Fig. C): The outstandingly large, U-shaped sterigma, with its inner edge of outer opening sharply defined and sclerotized, is characteristic. The ostium is small and roundish, and the ductus bursae long, tubular, and delicately folded longitudinally. The corpus bursae is oval and large, with a small, transverse, bicornuate signum. The anterior apophyses are reduced. Discussion. In facies, the moth is similar to, but slightly larger than, O. delacruzi f. restricta Warren and O. euchlora Prout, especially in the reduction of the submarginal pattern on the wings, but differing in: the scaling of wings, which is lighter green and semi-transparent; in the fine brown striation of both wings; and in the presence of sparse, long green hairscales on the wings. In the male genitalia, a long, distally bulbed appendage to the valva is characteristic of many species from different species groups of Oospila (Cook & Scoble, 1995), e.g. the O. quinquemaculata group, the O. albicoma group, and the large O. trilunaria group. These species usually have wings with beige, brown, or blackish markings, usually in form of blotches, or as a submarginal band. However, the species of the O. quinquemaculata group have a looped gnathos, while a pair of hooked gnathi occurs in O. bulava sp. nov. The species of the O. albicoma group have two processes to the apex of the valva, and the anellar complex is rhomb-shaped, pointing both dorsally and ventrally (Cook & Scoble, 1995). The Oospila trilunaria group is composite, containing some subgroups and species triplets. There are some species included with plain green wings (O. dicraspeda Prout; O. altonaria Jones; O. tricamerata Prout; O. decoloraria (Walker); O. pellucida Prout, 1916). These species were revised by Cook & Scoble (1995). The comparison of primary and subsequent descriptions of these species revealed that the characters of wing shape and markings of O. pellucuda, as given by Prout (1916), closely fit with those of the new species in the semi-transparent scaling on wings, combined with the sparse and fine dark strigulation, and with the white, thin marginal line (differing in the absence of pink pigment and in lacking the second white discal spot on the hindwings of the new species). O. pellucida and O. bulava, sp. nov., share some characteristics in the genitalia, such as slender valvae, the squarish tegumen, and the bases of sacculi separating the juxta and vinculum. However, O. pellucida differs in the shape of the appendage to the valva, which tapers distally, in the shape of juxta and sacculus. The sternite A 8 also has a specific shape. Female genitalia of both species have a large sterigma which is kidney-shaped in O. pellucida and longer Ushaped in the new species. The sterigma is much smaller in O. pelluc ida (Cook & Scoble, 1995). Differences in the genitalia structures are clear enough to confer the status of a new species. Biology. The specimens were collected from October to February in tropical rainforests in lowlands and up to 1500 m in elevation on the eastward-facing mountain slopes of the Andes. Etymology. The word 'bulava' means an ancient Russian reigning, threatening and fighting tool (club in English), which is similar to the long appendage (the "ampulla" as defined by Cook & Scoble (1995)) to valva in the described species,.The gender is feminine. The senior author is thankful to Dr Dirk Lloyd who kindly revised the English in the article. The field work of the first author was financed in part by the Estonian Museum of Natural History. The senior author's study was partially funded by grant 9174 of the Estonian Science Foundation and by institutional research funding (IUE 21 - 1) of the Estonian Ministry of Education and Research.Published as part of Lindt, Aare & Viidalepp, Jaan, 2015, Oospila bulava, a new emerald geometrid moth from South America (Lepidoptera, Geometridae, Geometrinae), pp. 142-144 in Zootaxa 4058 (1) on pages 142-144, DOI: 10.11646/zootaxa.4058.1.11, http://zenodo.org/record/24053
Inclusive rates from smeared spectral densities in the two-dimensional O(3) non-linear -model
No full textThis work employs the spectral reconstruction approach of Ref. [1] to determine an inclusive rate in the dimensional O(3) non-linear -model, analogous to the QCD part of . The Euclidean two-point correlation function of the conserved current is computed using Monte Carlo lattice field theory simulations for a variety of spacetime volumes and lattice spacings. The spectral density of this correlator is related to the inclusive rate for in which all final states produced by the external current are summed. The ill-posed inverse problem of determining the spectral density from the correlation function is made tractable through the determination of smeared spectral densities in which the desired density is convolved with a set of known smearing kernels of finite width . The smooth energy dependence of the underlying spectral density enables a controlled extrapolation in the inelastic region, yielding the real-time inclusive rate without reference to individual finite-volume energies or matrix elements. Systematic uncertainties due cutoff effects and residual finite-volume effects are estimated and taken into account in the final error budget. After taking the continuum limit, the results are consistent with the known analytic rate to within the combined statistical and systematic errors. Above energies where 20-particle states contribute, the overall precision is sufficient to discern the four-particle contribution to the spectral density
Predicting worsening heart failure hospitalizations in patients with implantable cardioverter defibrillators: is it all about alerts? A pooled analysis of nine trials
No full textAims To predict worsening heart failure hospitalizations (WHFHs) in patients with implantable defibrillators and remote monitoring, the HeartInsight algorithm (Biotronik, Berlin, Germany) calculates a heart failure (HF) score combining seven physiologic parameters: 24 h heart rate (HR), nocturnal HR, HR variability, atrial tachyarrhythmia, ventricular extrasystoles, patient activity, and thoracic impedance. We compared temporal trends of the HF score and its components 12 weeks before a WHFH with 12-week trends in patients without WHFH, to assess whether trends indicate deteriorating HF regardless of alert status. Methods and results Data from nine clinical trials were pooled, including 2050 patients with a defibrillator capable of atrial sensing, ejection fraction ≤ 35%, NYHA class II/III, no long-standing atrial fibrillation, and 369 WHFH from 259 patients. The mean HF score was higher in the WHFH group than in the no WHFH group (42.3 ± 26.1 vs. 30.7 ± 20.6, P < 0.001) already at the beginning of 12 weeks. The mean HF score further increased to 51.6 ± 26.8 until WHFH (+22% vs. no WHFH group, P = 0.003). As compared to the no WHFH group, the algorithm components either were already higher 12 weeks before WHFH (24 h HR, HR variability, thoracic impedance) or significantly increased until WHFH (nocturnal HR, atrial tachyarrhythmia, ventricular extrasystoles, patient activity). Conclusion The HF score was significantly higher at, and further increased during 12 weeks before WHFH, as compared to the no WHFH group, with seven components showing different behaviour and contribution. Temporal trends of HF score may serve as a quantitative estimate of HF condition and evolution prior to WHFH

Bartın iklim koşullarında doğal maddelerin (Baykal EM1 ve Biyohumus) Amaranthus caudatus var. bulava ve Amaranthus tricolor var. Valentina'da bazı morfolojik ve fizyolojik proseslere etkisi ve bu bitkilerin peyzaj mimarlığında kullanımı
No full textIn this study prepared as doctoral thesis, the effects of natural substances (Baykal EM1 and Biyohumus) on morphological and some physiological processes of Amaranthus caudatus var bulava and Amaranthus tricolor var valentina species, being annual plants grown naturally in Bartin province were researched. Morphological (length, number of leaves, width of leaves, number of flowers, the length of flowers, trunk diameter, fresh root weight) and some physiological (chlorophyll a, b, a+b, caratenoid, amaranthin, nitrogen, protein, DNA and RNA amounts) processes of Amaranthus caudatus var bulava and Amaranthus tricolor var valentina were taken into account. The study was carried out in two different ecosystems as in the garden of Günye Forest Enterprise of Bartin Forest Directorate in 2006 and 2007 and in the garden of Hacettepe University Inkumu facilities in 2007. In each of experimental areas 3 different applications (Baical EM1, Biohumus and Baical EM1+Biohumus) and control with 3 replicates and total of 12 lots were prepared. During vegetation period morphological measurements and physiological analyses were carried out in three times as in the beginnig of the vegetation and flowering and the end of the vegetation. In order to determine the effects on soil, samples were taken out from two different experimental areas in 2007 and soil analysis was carried out. Consequently, those natural substances had positive influence on the growth, development and adaptation capabilities of Amaranthus species. However, it was found that sole application of Baical EM1 affected more than Biohumus and there was no considerable difference between Baical EM1+Biohumus and Baical EM1.Doktora tezi olarak hazırlanan bu çalışmada doğal maddelerin (Baykal EM1 ve Biyohumus) Bartın yöresi yetişme koşullarında tek yıllık bitki türleri olan Amaranthus caudatus var bulava ve Amaranthus tricolor var valentina türleri üzerindeki morfolojik ve bazı fizyolojik proseslere olan etkileri araştırılmıştır. Çalışma kapsamında doğal maddelerin, Amaranthus caudatusvar bulava ve Amaranthus tricolor var valentina üzerindeki morfolojik (boyu, yaprak sayısı, yaprak uzunluğu, yaprak genişliği, çiçek sayısı, çiçek uzunluğu, gövde çapı ve taze kök ağırlığı) ve bazı fizyolojik (klorofil a, b, a+b, karotenoit, amarantin, azot, protein, RNA ve DNA miktarı) proseslere olan etkileri ortaya koyulmuştur. Çalışma, Bartın Orman İşletme Müdürlüğü Günye Orman İşletme Şefliği bahçesinde 2006 ve 2007 yıllarında, Hacettepe Üniversitesi İnkumu Araştırma ve Hidroloji Merkezinin bahçesinde, 2007 yılında olmak üzere iki farklı ekosistem ortamında gerçekleştirilmiştir. Her bir deneme alanında kontrol hariç 3 işlemli (Baykal EM1, Biyohumus, Baykal EM1+Biyohumus muameleli) 3 tekrar olmak şekilde 12 adet parsel oluşturulmuştur. Vejetasyon süresince üç dönemde (vejetasyon başlangıcı, çiçeklenme başlangıcı ve vejetasyon sonu) morfolojik ölçümler ve fizyolojik analizler yapılmıştır. Toprağa olan etkilerin belirlenmesi amacı ile 2007 yılında her iki deneme alanından örnekler alınarak toprak analizi yapılmıştır. Çalışmada kullanılan her iki doğal maddenin de Amaranthus türlerinin büyüme, gelişme ve adaptasyon yetenekleri üzerinde olumlu etki yaptığı, ancak Baykal EM1'in yalnız kullanımının Biyohumus'a oranla daha fazla etki yaptığı, Baykal EM1+Biyohumus ile Baykal EM1'in yalnız kullanımı arasında büyük bir farklılık bulunmadığı sonucuna varılmıştır

Type 1 diabetes (T1D) is one of the most common chronic diseases in young individuals. Diabetic nephropathy, being one of the most dangerous complications of T1D, progresses to end-stage renal disease within 10–15 years in 80%. The simultaneous kidney-pancreas transplant prevents insulin therapy and dialysis, thereby avoiding further progression of complications of diabetes. Normalization of carbohydrate metabolism and resolving of uremia after simultaneous kidney-pancreas transplant are beneficial for ocular structures. This article reviews studies on the pattern of changes in ocular structures in the post-transplant period. The procedure improves peripheral microcirculation of the bulbar conjunctiva and corneal innervation. Most studies demonstrate stabilization and improvement of the course of diabetic retinopathy as illustrated by the reduction in active vascular proliferation, need for retinal laser photocoagulation and vitrectomy. Meanwhile, some studi es failed to reveal any differences in the morphological functional status of the retina in the pre- and postoperative periods. An increase in cataract rate among simultaneous kidney-pancreas transplant recipients receiving immunosuppressant therapy remains a challenge.

Stimulací indukovaná kardiomyopatie a elektro-mechanická komorová dyssynchronie - nové neinvazivní diagnostické metody a biomarkery metabolismu kolagenu
No full textRandomizované srovnání stimulace Hisova svazku proti pravokomorové myokardiální stimulaci - vliv na funkci levé komory a biomarkery metabolismu kolagenu Úvod: Pravokomorová stimulace (RVP, z anglického right ventricular pacing) může vyústit v rozvoj stimulací indikované kardiomyopatie. Stimulace Hisova svazku (HBP, z anglického His bundle pacing) je metodou fyziologickou a k rozvoji stimulací indikované kardiomyopatie by vést neměla. Doposud není známo, zdali specifické markery metabolismu kolagenu reflektují rozdíl HBP a RVP nebo zdali mohou predikovat pokles ejekční frakce levé komory srdeční (EFLK) vlivem RVP. Cíle: Cílem této studie bylo srovnání vlivu HBP a RVP na EFLK a na markery metabolismu kolagenu v krevním séru. Metody: 92 pacientů s vysokým rizikem rozvoje stimulací indukované kardiomyopatie bylo randomizováno k HBP nebo RVP. Jejich klinické charakteristiky a sérové hodnoty TGF-β1, MMP-9, ST2, TIMP-1, a Gal-3 byly odebrány před a 6 měsíců po implantaci kardiostimulátoru. Echokardiografické vyšetření bylo provedeno a vyhodnoceno taktéž před a 6 měsíců po implantaci kardiostimulátoru. Výsledky: 53 pacientů bylo randomizováno k HBP a 39 k RVP. HBP selhal u 10 pacientů, kteří poté přešli do skupiny RVP. Obě skupiny měly před implantací stejné klinické charakteristiky, ale pacienti ve skupině RVP...A randomized comparison of His bundle pacing versus RV pacing: effect on left ventricular function and biomarkers of collagen metabolism Background: Right ventricular pacing (RVP) may result in pacing-induced cardiomyopathy (PICM) in some patients. His bundle pacing (HBP) is a method of physiological pacing, which should not lead to PICM. There are some known risk factors, which are, however, not strong enough to reliably predict PICM development. It is unknown whether specific sera biomarkers of collagen metabolism reflect differences between His bundle pacing (HBP) and RVP or predict a decrease in left ventricular function during RVP. Aims: To compare the effect of HBP and RVP on the LV ejection fraction (LVEF) and on sera markers of collagen metabolism. Methods: Ninety-two high-risk PICM patients were randomized to HBP or RVP. Their clinical characteristics, echocardiography, and sera levels of TGF-β1, MMP-9, ST2, TIMP-1, and Gal-3 were studied before and six months after pacemaker implantation. Results: Fifty-three patients were randomized to HBP and 39 patients to RVP. HBP failed in 10 patients, who then crossed over to the RVP group. Both groups had same clinical characteristics at the baseline, but patients with RVP had significantly lower LVEF compared to HBP after six months of pacing (−3 % and −3...Department of Cardiology 3FM CU and UHKVKardiologická klinika 3.
