Subcutaneous dirofilariasis of maxillofacial localization - a rare clinical case

Dirofilariasis is a tropical helminthosis caused by nematodes - filariae. The are characterized by long incubation period, slow disease development and its long chronic course. Dirofilariasis can be catched from humans and animals, it is transmitted through insect bites (mosquitoes, gadflies, sand flies, midges). Dirofilariasis is endemic to areas with warm and humid climate. In Russia, the disease is atypical, with the absence of mature nematodes and microfilariae in the tissues. This disease is not typical for the Republic of Tatarstan and only isolated cases of parasite localization in the eyeball were previously recorded. The article presents a rare clinical case of subcutaneous localization of nematode of dirofilaria in the maxillofacial region. The patient was diagnosed with tumor-like neoplasm of the maxillofacial region, on the removal of which a live incapsulated parasite was found. The patient had no history of visiting endemic countries

Utilization of photon orbital angular momentum in the low-frequency radio domain

We show numerically that vector antenna arrays can generate radio beams which exhibit spin and orbital angular momentum characteristics similar to those of helical Laguerre-Gauss laser beams in paraxial optics. For low frequencies (< 1 GHz), digital techniques can be used to coherently measure the instantaneous, local field vectors and to manipulate them in software. This opens up for new types of experiments that go beyond those currently possible to perform in optics, for information-rich radio physics applications such as radio astronomy, and for novel wireless communication concepts.Comment: 4 pages, 5 figures.

Analysis of distant cardiovascular events depending on the biomarker profile in patients with myocardial infarction

Acute coronary syndrome (ACS) and its complications is one of the main reasons of mortality and invalidation in the world. New biomarkers, such as ST2, NT-proBNP и Pentraxin-3 (Ptx-3) present much more opportunities in the diagnostics of diseases and risk of its development.Aim. To investigate standards and “new” biomarkers in different variants of MI and cardiovascular events in 1 year after MI.Material and methods. In 180 patients with MI (61,4±1,7 years) we determined the serum concentration of standard and “new” (ST2, NT-proBNP, Ptx-3) biomarkers in groups with Q/non-Q, STEMI and NSTEMI and the endpoints (MI, strokes, repeated hospitalizations and sudden deaths) in 1 year (384,3±21,2 days) after MI.Results. Patients with Q-MI and STEMI had higher risk of unfavorable cardiovascular events (p&lt;0,05). Ptx-3 &gt;43,9 ng/ml was shown to be risk factor for sudden death (sensitivity 70,0%, specificity 52,9%), and &gt;125,9±0,06 ng/ml (74,1% and 44,1%) — of recurrent MI.Conclusion. NT-proBNP, ST2 and Ptx-3 showed prognostic value in the diagnostics of unfavorable cardiovascular endpoints

Effect of perforated disc height and filter basket on espresso coffee carbohydrates content and composition

The instrumental equipment of an espresso coffee machine has a remarkable influence on the extraction of the espresso coffee (EC). This study aims to evaluate the effect of different perforated disc heights and filter baskets, two fundamental parts of the espresso coffee machine, on EC carbohydrates content and composition. Four different heights (4-7 mm) of perforated discs and two different filter baskets were used to prepare Italian style EC and evaluate the feasibility of lowering the amount of ground coffee while keeping the same quality of the standard Italian espresso. Arabica and Robusta coffee beans, with 12 and 14 g of roasted coffee powder, were used to prepare 40 mL of EC, split in two cups. The content of total solids, high molecular weight material (HMWM), and polysaccharides, such as galactomannans (GM) and arabinogalactans (AG), were compared. The results show that the increase of the height of perforated disc affected the extraction of the polysaccharides content in the cup, with a decrease of GM and AG. As a conclusion, the configuration of perforated disc height and the filter used was shown to modulate the chemical profile of EC brew, with impact on espresso coffee cup quality

Prognostic significance of a combination of novel biomarkers in the long-term stratification of adverse outcomes in patients with ST-segment elevation myocardial infarction

A multi-marker approach for assessing the prognosis of patients with ST-segment elevation myocardial infarction (STEMI) is a promising strategy.Aim. To assess the potential prognostic power of soluble growth stimulation gene-2 (sST2), pentraxin 3 (PTX3), and N-terminal pro-brain natriuretic peptide (NT-proBNP) in stratification of the risk of major cardiovascular events (CVE) during 2-year follow-up after STEMI.Material and methods. In 154 patients with STEMI, serum concentrations of NT-proBNP, sST2, and PTx-3 were determined upon admission to hospital. During the two-year follow-up period (734,2±61,2 days), correlation of biomarker concentrations with the risk of a composite endpoint (myocardial infarction + stroke + hospitalization due to cardiovascular disease + cardiovascular death) was analyzed.Results. In the 2-year follow-up, CVE were observed in 81 (55,1%) patients (CV death (n=33; 22,1%), recurrent MI (n=28; 18,.8%), stroke (n=8; 5,4%), hospitalization due to cardiovascular disease other than MI, stroke or cardiovascular death (n=12; 8,2%)). NT-proBNP (HR, 1,19; 95% CI, 1,018-1,32, p&lt;0,001) and sST2 (HR, 1,000013; 95% CI, 1,00-1,001, p=0,007) correlated with CVE in contrast to PTX-3 (HR, 1,178; 95% CI, 0,798-1,73, p=0,434). The most accurate prediction of CVE was shown in the model with three biomarkers (AIC=831, BIC=843, LR=12,45, p=0,033). Conclusion. After STEMI, NT-proBNP and sST2, but not PTX-3, predicted CVE, while 3-marker analysis showed higher accuracy compared to single- and doublemarker
