The effects of mannanoligosaccharide and organic zinc on some electrocardiographic and haematologic parameters in broilers

Bu araştırma, mannanoligosakkarit (MOS) ve organik çinkonun (Zn) broylerlerde bazı elektrokardiyografik ve hematolojik parametreler üzerine etkisini araştırmak amacıyla yapıldı. Toplam 60 adet, bir günlük yaşta, etlik erkek civciv (Ross-308) kullanıldı. Civcivler, biri kontrol diğer üçü deneme grubu olmak üzere 4 gruba ayrıldı. Kontrol grubuna MOS ve organik Zn ilavesiz bazal rasyon verildi. Uygulama gruplarının bazal rasyonlarına, MOS (1 g/kg), organik Zn (80 ppm) ve MOS (1 g/kg) organik Zn (80 ppm) katıldı. Kırk iki günlük deneme süresi sonunda, bazı elektrokardiyografik ve hematolojik parametreler belirlendi. Kontrol ile karşılaştırıldığında, MOS grubuna ait T (P-T) dalgası ve QT aralığı süreleri istatistiksel olarak daha kısa bulundu (P0.05). Organik Zn ve MOS Organik Zn grubu PR aralığı değerinin kontrolden yüksek olduğu (P0.05) gözlendi. Frontal düzlemde kalbin ortalama elektriksel ekseninin MOS grubunda sola kaydığı (-35.87) belirlendi (P0.05). Kontrolle karşılaştırıldığında, MOS ve organik Zn grubuna ait hematokrit değerlerin düşük (P0.05) ve organik Zn grubuna ait heterofil/lenfosit (H/L) oranının ise daha yüksek (P0.05) olduğu saptandı. Bu araştırmanın sonuçları, broyler rasyonlarına MOS ve organik çinko ilavelerinin bazı elektrokardiyografik ve hematolojik değerler üzerine önemli etkiler yaptığını gösterdi.This study was conducted to investigate the effects of mannanoligosaccharide (MOS) and organic zinc (Zn) supplementation on some electrocardiographic and hematologic parameters in broilers. A total of 60, Ross-308 one-day-old male broiler chickens were used. Chicks were divided into 1 control and 3 treated groups. The control group was fed a basal diet without supplements of MOS and organic Zn. In treated groups, MOS (1 g/kg), organic Zn (80 ppm) and MOS (1 g/kg) organic Zn (80 ppm) were added into the basal diet. At the end of the 42-day treatment period, some electrocardiographic and haematological parameters were determined. The duration of T (P-T) wave and QT interval in MOS treatment group were significantly decreased (P<0.05) as compared with control. The durations of PR interval in organic Zn group and group supplemented with MOS organic Zn was significantly higher as compared with control. The mean electrical axis in MOS group shifted leftward (-35.87°) in the frontal plane (P<0.05). The hematocrit values in MOS and organic Zn treatment groups were significantly lower (P<0.05) than in control and the H/L ratio in organic Zn group was significantly higher (P<0.05) than in control. The results showed that the supplementation of MOS and organic Zn to the diet of broilers resulted in marked effects on some electrocardiographic and haematological parameters

The importance of results of MEFV gene analysis in cases prediagnosed as "familial mediterranean fever"

Amaç: Sunulan çalışmada Ailesel Akdeniz Ateşi (AAA) ön tanısı almış hastalarda“familial Mediterranean fever locus”-MEFV gen mutasyonlarının araştırılması amaçlanmıştır. Gereç ve yöntem: AAA ön tanısı konan 83 olguda MEFV geninde en sık mutasyon tanımlandığı bildirilen M680I, M694V, V726A ve E148Q mutasyonları PCR amplifikasyon sonrası kit kullanılarak (PRONTOTM AAA Basic) incelenmiştir. Bulgular: Değerlendirilen 83 olgunun 29’ unda bu bölge için mutasyon tanımlanamazken 54 olguda mutasyon tanımlanmıştır (%65). Olguların 14’ ünde homozigot mutasyon bulunmuştur (%17). Homozigot mutasyon bulunan 14 olgunun dördünde M680I/M680I, onunda M694V/M694V saptanmıştır. Sonuçlar klinikte daha ağır tablo ile seyrettiği ileri sürülen M694V ve M680I mutasyonlarının bizim içinde bulunduğumuz toplumda çok sık gözlendiğini göstermektedir. 40 (%48) olguda heterozigot mutasyon tanımlanmıştır. Heterozigot mutasyon tanımlanan 40 olgunun yedisinde bu gene ait iki mutasyon gözlenmiştir-“compaund heterozygote” (M680I/M694V iki olguda, M694V/V726A üç olguda, E148Q/M694V bir olguda, M680I/V726A bir olguda). Sonuç: Bulgular toplumumuzda MEFV genine ait mutasyonların yüksek taşıyıcılık oranını göstermesi yönünden ilgi çekicidir. Günümüzde AAA tanısında MEFV gen mutasyonlarının bulunması önemli bir tanı kriteridir.Purpose:In this study we aimed to determine &amp;#8220;familial mediterranean fever locus&amp;#8221; MEFV gene mutation in cases with a prediagnosis of familial mediterranean fever (FMF). Material and methods: MEFV mutations reported as being frequently seen (M680I, M694V, V726A and E148Q) were analyzed with PCR amplification kit (PRONTOTM FMF Basic, Savyon Diagnostic Ltd.) in 83 cases who were suspected of having FMF. Results: In 29 out of 83 cases, no mutations were observed whereas in 54 (65%) out of 83 cases, mutations in MEFV locus were observed. In 14 cases (%17), homozygote mutation of one locus was found. M680I/M680I homozygote mutation was observed in four cases and M694V/M694V homozygote mutation in ten cases. These results demonstrate that M694V and M680I (these mutations are suggested to have more serious clinic patterns) mutations are seen frequently in our country. Forty cases (48%) had heterozygote mutations in MEFV gene. Seven out of 40 cases had compound heterozygote mutations (M680I/M694V mutations in 2 cases, M694V/V726A mutations in three cases, E148Q/M694V mutations in one case, and M680I/V726A mutations in one case). Conclusion: Our results represent a high carrier rate of mutations in MEFV gene in our country. In our era, genetic analysis of MEFV gene is an important diagnostic criteria for the FMF disease

Characterization of LEDs for visible-light communications

Recent advances in solid-state technologies have enabled the development of light-emitting diodes (LEDs) with favorable features such as long life expectancy, low-power consumption, and reduced heat dissipation. Visible-light communication (VLC) is a short-range wireless access technology that deploys LEDs as wireless transmitters in addition to their primary task of illumination. The major limitation for the design of high-speed VLC systems is the electrical (modulation) bandwidth of the LED. In this study, we investigate the electrical characteristics of a number of off-the-shelf LEDs. Specifically, we determine their frequency responses and match them to their small-signal models. The electrical bandwidths of measured LEDs vary from 250 kHz to 20 MHz and depend on the emitted color and internal circuitry. As a verification of our measurements, we use the sample LEDs as a transmitter in a VLC system setup and determine the supported data rates. The equivalent circuit model is utilized to compare with the measured modulation characteristic of the LED. Furthermore, the bias current effect on the modulation bandwidth is presented

Wpływ zmian tandemowych na parametry hemodynamiczne: badanie eksperymentalne

Background: The morphology and extensity of the stenotic lesion is crucial as well as the obstruction ratio. It is well known that the complexity of lesions has a direct impact on endovascular treatment (PTCA/stent); however, the arrangement of the lesions is underestimated and not well studied. Aim: We sought to evaluate the haemodynamic effects of different stenotic lesion models and arrangements in vitro. Methods: Vascular circulation was simulated in vitro. Oxygenator, tubing set, polytetrahidroflouroethylene synthetic graft, pressure and flow rate, sensors were used to build the simulation model. Measurements of isolated short, isolated long, identical stenotic tandem short, identical stenotic tandem long, sub-critical long, and critical short lesion combinations were performed and haemodynamic parameters were recorded. Results: Tandem lesions were more likely to result in critical stenosis comparing single lesions with the same obstruction ratio. This difference became more significant as the obstruction ratio was raised. Tandem long lesions also resulted in more critical stenosis than tandem short lesions. It can be claimed that tandem lesions can result in more flow restriction with reference to single lesions with the same stenotic ratio. Contrary to expectations, tandem short lesions were found to be more stenotic compared with the same degree long individual lesions. Conclusions: It is effortless to give the decision for simple, discrete and individual lesions, while the ideal decision for long and complicated lesions may remain unclear. Even if these “grey zone” lesions are considered non-critical while investigating them one by one, it must be kept in mind that the overall stenotic effect of these lesions may lead to more haemodynamic impairment.Wstęp: Morfologia i długość zwężeń tętnic mają równie istotne znaczenie, jak stopień zwężenia. Powszechnie wiadomo, że złożoność zmian w tętnicach ma bezpośredni wpływ na leczenie wewnątrznaczyniowe (przezskórna wewnątrznaczyniowa angioplastyka wieńcowa/stent), jednak znaczenie konfiguracji zmian nie jest doceniane ani nie zostało wystarczająco zbadane. Cel: Celem niniejszej pracy była ocena efektu hemodynamicznego różnych rodzajów zwężeń tętnic i ich konfiguracji w wa¬runkach in vitro. Metody: Wykonano model do symulacji układu naczyniowego w warunkach in vitro. Wykorzystano do tego oksygenator, zestaw drenów, syntetyczną protezę naczyniową z politetrahydroflouroetylenu oraz czujniki ciśnienia i przepływu. Przeprowa¬dzono pomiary przy różnych konfiguracjach zmian (izolowane krótkie zwężenie, izolowane długie zwężenie, dwa identyczne krótkie zwężenia w układzie tandemowym, dwa identyczne długie zwężenia w układzie tandemowym, kombinacja długiego zwężenia podkrytycznego i krótkiego zwężenia krytycznego) i zarejestrowano parametry hemodynamiczne. Wyniki: Zmiany tandemowe wiązały się z większym ryzykiem krytycznego zwężenia niż pojedyncze zmiany o takim samym stopniu zwężenia światła naczynia. Różnica była tym większa, im większy był stopień zwężenia. Długie zwężenia tandemo¬we również powodowały więcej krytycznych zwężeń niż krótkie zwężenia w układzie tandemowym. Można stwierdzić, że zmiany tandemowe powodują większe ograniczenie przepływu niż pojedyncze zwężenia o takim samym stopniu zwężenia światła naczynia. Przeciwnie niż oczekiwano, okazało się, że krótkie zwężenia tandemowe powodują większe zaburzenia niż pojedyncze długie zwężenia o tej samej średnicy. Wnioski: Decyzje dotyczące leczenia nieskomplikowanych, ograniczonych i izolowanych zmian naczyniowych nie są trudne, natomiast w przypadku długoodcinkowych i złożonych zmian optymalna decyzja może być nieoczywista. Nawet jeśli te zmiany „szarej strefy” są uważane za niekrytyczne, w przypadku gdy ocenia się je niezależnie od siebie (każdą osobno), należy pa¬miętać, że sumaryczny efekt zwężenia łożyska naczyniowego może spowodować poważniejsze zaburzenia hemodynamiczne
