Published: December 2019

Background: Cuscuta epithymum (CE) is an established medicinal herb utilized for treating psychosis in Persian medicine. The aim of this study was to investigate the effect of CE combined with risperidone on the clinical symptoms and the cognitive impairment in patients diagnosed with schizophrenia. Materials and Methods: In this triple-blind randomized placebo-controlled trial, the intervention group received a dose of 500 mg of CE in the form of a capsule to be taken twice a day accompanied by an appropriate dose of risperidone. The control group was presented with a placebo identical to that of the CE capsule plus the allocated dose of risperidone. The PANSS and SCoRS questionnaires were used to assess the status of subjects prior to the initiation of the intervention as well as being put to use at the end of the second, fourth, and eighth week post-intervention. Registering and recording intel concerning positive and negative symptoms felt by participants (PANNS), and a test to assess the cognitive impairment of the individuals. Results: After eight weeks of treatment, all negative and positive symptoms besides hostility and somatic concern exhibited a significant improvement in the CE group (P <0.05). In contrast, the CE placebo group displayed no substantial improvement in the cases of the positive, negative and general symptoms (P>0.05) regarding cognitive impairment, after eight weeks of treatment, all symptoms were greatly improved in the CE group (P<0.05), while the effect of the placebo  on the patients cognitive impairment remained mostly stationary (P>0.05). Consequently, after eight weeks after the intervention, we can determine that the CE treatment has been noticeably more effective at improving positive, negative and cognitive symptoms of patients with schizophrenia. Conclusion: The results of this study demonstrated that CE, possessing possible antioxidant and neuroprotective properties, safely improved the positive and negative symptoms, and cognitive impairment of patients with schizophrenia.[GMJ.2019;8:e1334]

Published: December 2019

The paper demonstrates the results on the effect of new specimen Vetom 20.76 on concentration of leukocytes in the blood of geese on the basis of the predatory fungus Artusbotus oligospora. In order to achieve the goal of the experiment, one control group and six experimental groups were arranged on the principle of paired analogues. Each group contained 10 geese aged 1 month. The geese from the experimental groups received Vetom 20.76 in different doses in the morning with water once a day: the geese of the 1st experimental group - dose of 0.5 ppm/kg of live weight during 15 days; 2nd experimental group - 1 ppm/kg of live weight during 15 days; 3rd experimental group - 2 ppm/kg of live weight during 15 days, 4th experimental group - 0.5 ppm/kg live weight during 30 days, 5th experimental group - 1 ppm/kg live weight during 30 days and 6th - 2 ppm/kg live weight during 30 days. The geese of control group didn’t receive the specimen. The concentration of leukocytes in the blood of experimental geese increases in the period of specimen application as well as in the period of its aftereffect. If Vetom 20.76 is prescribed for 15 days, the effect of leukopoiesis stimulation finishes on the 30th day. If the specimen is applied during 30 days, the leukocytes in the blood continue to increase up to the 60th day. This long-term application of Vetom 20.76 dosed 0.5ppm/kg increases leucocytes within the physiological norm. Application of higher doses (1 and 2 ppm/kg) the leukocyte concentration conforms to the physiological norm

Published: December 2019

The paper explores the urgency of increasing efficiency of breeding Red-and-White dairy cattle that take the main part of the population in the Krasnoyarsk region (69.7%), the immunogenetic characteristics of animals that belong to Montwick Chiftein and Pabst Hoverner (n=52) lines. The research on the blood groups of cows were conducted in the laboratory of immunogenetic analysis of Krasnoyarskagroplem. The authors revealed the differences in the incidence of specific antigens in the cows of two lines. The article found out that antigens A’2, B2, E’3, O3, and T2 (P>0.95-0.99) were found to be more frequent in Montwick Chiftein line cows, and antigen P2 (P>0.95) wasfound in Pabst Governer line cows. It was also revealed that the most rare antigens in the Montwick Chifthein line are antigens A’, A’1, O2, O4, Y1, R1, X1, M and E’2, and antigens B’’, O4, U and U’’in the Pabst Governer line. Interestingly, the authors identified the antigens that were not present in the animals of both lines and in each line separately. The average index of antigen incidence in the cows of each line showed a relatively low value. Due to this the authors made a conclusion about a high degree of heterozygosity of the studied individuals. The index of genetic similarity among the animals of two lines demonstrates a high value of 0.863. The polymorphism of the antigens in the EAF-V locus was studied and a significant incidence predominance in cows of the F allele over the V allele was found out. The impact of genotype according to the EAF-V locus on dairy productivity and live weight of the cows was determined: in the Montwick Chifthein line, cows with the FF genotype (5986,60172,41 kg) had a higher yield, in the Pabst Governer line - with the FV genotype (5914,20208,19 kg). Animals of both lines that had genotype V/V had higher live weight parmeters than animals with genotypes F/V and F/F. The comparative analysis of the obtained results was carried out with the results of other Russian authors who conducted similar studies.

Published: December 2019

The authors argue the impact of environmental stress factors on physiological status of Simmental cattle of local selection, adapted to conditions of breeding in Arctic zone, characterized by weak forage base and unfavorable extreme natural conditions. They found out the total number of red blood cells and the level of hemoglobulin in the investigated animals in the peripheral blood is 14.55% lower than the standard values on the average. The granulocyte concentration in the leukocyte formula exceeds the standard by 1.2%. The level of total protein in the blood serum is significantly higher than the standard one: in calves - by 38.01, in cows - by 17% (P0.001). In peripheral blood, dysproteinemia is observed in the animals. The impact of environmental stress factors on neutrophil opsonophagocytic reaction (ORP) parameters, such as phagocytic activity of neutrophils (FA), phagocytic number (FN), phagocytic index (PI), in vitro, has been determined. The greatest growth of phagocytic activity was observed in the winter stable period, which exceeded the physiological standard by 5.99%. The FA is relatively high in other seasons and corresponds to the upper limit values of the multiyear average. When studying the qualitative characteristics of microphages - phagocytic number - it was revealed that the maximum values are observed in cows in winter-spring period (10,3±1,6 and 10,0±0,7 m.t.), and the minimum - in summer (7,9±0,9 m.t.). When estimating the phagocytic index in the opsonophagocytic reaction, the authors revealed the profound growth of PI values in winter (8.1±1.4 m.t.), which is 34.56% higher than in summer. The data obtained confirm the severity of the impact of environmental conditions, in particular, seasonal changes that play specific role in the adaptive response and in the preservation of the overall organism resistance.
THE CHANGES IN BLOOD PARAMETERS OF COWS INFECTED BY LEUCOSIS IN CASE OF COMPLICATIONS WITH ACUTE ANAPLASMOSIS
Authors: Loginov S. I.
Published: December 2019

The authors found out that some districts of the Tomsk region are unfavourable in respect to bovine anaplasmosis. In enzootic areas with bovine anaplasmosis the bovine leukemia was observed in susceptible animals. The research focuses on hematological and immunological changes of the blood of cows infected with leukemia during the acute anaplasmosis. That was found out in spring while intense activity of ixodids (the end of April). The researchers arranged two groups of Black-and-White cows aged 2.5-3 years infected with leukemia virus. The 1st group was infected with acute anaplasmosis cow leukemia virus, the 2nd group (control) was infected with anaplasm-free cow leukemia virus. The changes in the hematological pattern of cows infected with leucosis in case of complications with acute anaplasmosis consist in eosinophilia, neutropenia, lymphocytosis and monocytopenia. The changes in the immune system of cows were less noticeable and characterized by a moderate increase in IgG and high titers of antibodies to leukemia virus. The researchers assume that there is a significant sensitization of the humoral component of the immune system of cows infected with leucosis in case of complications with acute anaplasmosis. The noticeable lymphocytosis in the certain cows infected with leukemia virus in case of complications with acute anaplasmosis should be taken into account when making a diagnosis for cattle leukemia. This occurence in the hematological picture of blood can be characterized as a temporary leukemia reaction, causing a false positive result of hematological test on leukemia.

Published: December 2019

X-ray microanalysis methods have significantly expanded the functionality of electron microscopy. X-ray microanalysis is widely applied in activities, which deal with plant physiology. The paper explores the functioning of the stomach apparatus of fodder beans (Vícia fába). The regulation of the stomatal function depends on the potassium concentration in the closing cells. The authors investigated the infestation of wheat leaves with mildew (Erysiphe graminis) (Triticum astivum) and obtained the data that reveal the changes in the elemental composition of tissues in the affected area. This has contributed to find out the role of various elements during the infectious process in case of wheat plants with powdery dew contamination. The paper summarizes the materials on the application of X-ray microanalysis in phytopathology. It stipulates the participation of calcium in the formation of the mechanism of nematode capture in different age colonies of predatory fungi Arthrobotrys oligospores Fres was revealed. The data on tissue barrier in wheat roots, where the transport of both sodium and chlorine salting elements and potassium and calcium macro elements is controlled, are obtained. The authors show that transporting of these elements is regulated by active mechanisms in the endoderm cells. The article demonstrates the results of X-ray microanalysis aimed at determining the content of elements of magnesium, phosphorus, sulfur, potassium and calcium in soybean leaves affected by various diseases. The authors observed the changes in potassium, calcium, magnesium and phosphorus concentration in leaves with bacterial burn, ascochytosis and alternative. They argue the participation of elements in formation of plant resistance to disease and the role of these elements in the physiology of the infectious process.

Published: December 2019

The authors argue the reindeer’s vascular morphology is not sufficiently investigated. They focus on the distal part of the thoracic and pelvic limbs, which the reindeer steps on the ground and hurts it often, as it leads to necrobacterial lesions in summer. In the postnatal period of the reindeer growth, the most intensive one in the length and diameter of the main arteries is observed in the first year, especially in the first month. During this period, the newborn deer gets into the new conditions of existence and the organs of movement become more and more functional. By the age of 3 - 3.5 years, the growth of the main arteries in length is almost over. The paper explores the features of blood supply of the thoracic limbs of a domestic reindeer, caused by the prominent growth of the second and fifth fingers. The absolute growth of arterial length in newborns and deers aged 0.5 months is 0.6 cm per day. In the following years of life, the length is reduced to 0.03 cm in the reindeers aged 3 y.o. The relative diameter of the arteries to the limb length in the postnatal period decreases from 4.4% in newborns to 3.3% in old deer. The irregularity of changes in the absolute and relative development of the thoracic limb arteries can be explained by different growth of blood vessels, bones, joints and limb muscles.
GROUNDS FOR THE DEVELOPMENT AND APPLICATION OF PRECISION TECHNOLOGIES IN ORDER TO KEEP SPECIFIC BEEF CATTLE UNDER THE CONDITIONS OF YAKUTIA
Authors: Sleptsov I. I.
Published: December 2019

The article demonstrates the research results on climate conditions of the Republic of Sakha (Yakutia) and grounds of application of precision technologies for breeding Kalmyk beef cattle on the basis of specific natural and climate conditions of Yakutia. The history of animal breeding says that enhancement of local livestock’s producing qualities in different years contributed to the fact that the stud breeds of cattle, generally dairy and beef-dairy types, were imported. Animals of the beef productivity type, known as Kazakh Whitehead cattle, the Hereford, the Kalmyk, and the Calloway breeds, were imported in order to receive crossbred youngsters with improved feeding and beef parameters. In all the time of the development, the cattle breeding in the region had beef-dairy types. The beef breeds were imported in the last decade for targeted purebred breeding and development of the beef industry for production of the beef. Therefore, in 2012, there were imported 200 animals of the Hereford cattle; the Kalmyk breed has been imported since 2013. The experience has shown that naturalizing of purebred animals to the breeding conditions of Yakutia was extremely stressful, and was followed by the diseases, falls, and decreasing of seed stock’s reproductive indicators. Particularly negative impact was observed on the animals of the highly productive Hereford breed, and this caused gradual degeneration of the breed under conditions of Yakutia. Although, specific natural and climate conditions of Yakutia significantly differ from that in other regions with developed beef cattle breeding, the animals of the Kalmyk breed, which was bred on the basis of the native steppe cattle, were relatively well adapted to the harsh conditions of the region. The authors argue the necessity and urgency of adaptive technologies development on specialized beef cattle breeding with respect to the harsh local conditions.

Božićna zvijezda (Euphorbia pulcherrima Willd. ex Klotzsch.) jedna je od najprodavanijih cvatućih lončanica čija je potražnja najveća krajem studenog i tijekom prosinca za kad se i planira većina proizvodnje. Za uspješnu proizvodnju božićne zvijezde bitno je imati na raspolaganju svjetao i zračan zaštićeni prostor, dobro podešeno centralno grijanje i automatizirano prozračivanje te opremu za regulaciju duljine dana. Zahtjevi božićne zvijezde prema temperaturi, svjetlosti, hranivima, supstratu i ostalim čimbenicima vrlo su visoki tako da je potrebna stroga kontrola proizvodnje. Cilj ovog rada je prikazati taksonomsku pripadnost i porijeklo vrste, način uzgoja te mjere njege i održavanja u primjeni. Rod Euphorbia pripada porodici Euphorbiaceae, a potječe iz Meksika. Najčešće se uzgaja vegetativno iz reznica, premda može i generativno iz sjemena. U uzgoju i primjeni traži svijetlo mjesto, blago kiseo supstrat, redovitu prihranu i umjereno zalijevanje. Najčešće se koristi kao cvatuća lončanica za dekoraciju interijera u vrijeme božićnih blagdana, premda se može koristiti i kao cvjetna vrsta za rez.
Proizvodnja pamuka u Hercegovini nakon Drugog svjetskog rata

Published: January 2020

Pamuk je jedna od najvažnijih tekstilnih biljaka u svijetu. Proizvodnja i upotreba pamučnog vlakna prvi put se spominje u Indiji. Iz Indije je pamuk prenesen u Kinu, Egipat i Grčku. Na području Hercegovine pamuk je uveden u poljoprivrednu proizvodnju odmah nakon završetka Drugog svjetskog rata. Premda u Hercegovini postoje povoljni ekološki uvjeti za njegov uzgoj, proizvodnja pamuka nije se raširila iz dva osnovna razloga. Poljoprivreda južne Hercegovine tradicionalno je orijentirana na uzgoj vinove loze, mediteranskih voćnih vrsta, duhana i povrtnih kultura. Drugi razlog je otpor vlastima koji su protivno volji poljoprivrednih proizvođača nastojali uvesti kulturu pamuka u agrar južne Hercegovine.

Penelitian ini bertujuan untuk mengetahui seberapa besar pengaruh aktiva lancar dan modal sendiri terhadap profitabilitas. Penelitian dilaksanakan pada PD. Sri Tanjung Kabupaten Indramayu. Data diperoleh dari Laporan keuangan dalam bentuk neraca dan laporan laba rugi dari tahun 2010 sampai dengan tahun 2015.

Berdasarkan dari hasil analisis data yang diperoleh koefisien korelasi X1 terhadap Y sebesar 0,081 yang berarti bahwa perolehan aktiva lancar terhadap profitabilitas mempunyai hubungan positif dan keeratan hubungan termasuk dalam kategori sangat tinggi. Koefisien korelasi X2 terhadap Y sebesar 0,647 yang berarti pula bahwa perolehan modal sendiri terhadap profitabilitas mempunyai hubungan positif dan sangat kuat. Koefisien korelasi antara X1 terhadap X2 sebesar 0,903 yang berarti bahwa perolehan aktiva lancar terhadap modal sendiri mempunyai hubungan positif dan sangat kuat.

Nilai koefisien determinasi (Kd) yang diperoleh dalam penelitian ini dari X1 terhadap Y diperoleh hasil sebesar 33,80%, hal ini menjelaskan bahwa perolehan aktiva lancar terhadap profitabilitas usaha sebesar 33,80%, sedangkan sisanya sebesar 66,20%  yang merupakan faktor-faktor lain yang mempengaruhi profitabilitas. Pada X2 terhadap Y diperoleh hasil sebesar 41,86% hal ini berarti menunjukkan adanya modal sendiri memiliki pengaruh terhadap profitabilitas sebesar 41,86% yang sisanya sebesar  58,14% dipengaruhi oleh faktor-faktor lain yang mempengaruhi profitabilitas

Untuk melihat ada tidaknya pengaruh antara aktiva lancar terhadap profitabilitas maka digunakan uji hipotesis dengan membandingkan thitung dengan ttabel. Untuk melihat pengaruh aktiva lancar terhadap profitabilitas hasil yang diperoleh dalam Uji t dimana thitung lebih kecil dari ttabel (1.115 < 2.776) dan tingkat kesalahan mencapai 5%.  Artinya tidak ada pengaruh aktiva lancar terhadap profitabilitas. Kemudian untuk pengaruh modal sendiri terhadap profitabilitas hasil yang diperoleh dari Uji t yaitu dimana thitung lebih kecil dari ttabel (1.967 < 2.776), artinya tidak ada pengaruh modal sendiri terhadap profitabilitas.

Published: December 2019

Akhir-akhir ini perkembangan teknologi semakin pesat, metode interaksi dan komunikasi antara pengguna dengan komputer adalah salah satu tuntutan perkembangan teknologi. Berbagai macam pembaharuan teknologi mengusahakan untuk meminimalisir berbagai macam perangkat menjadi satu agar lebih mudah digunakan. User lebih membutuhkan peralatan komunikasi yang bersifat alami karena tidak membutuhkan kontak langsung dengan peralatan input. Misalnya dengan gerakan dari tubuh manusia didepan kamera komputer sudah bisa menginterpretasikan. Untuk mengatasi masalah tersebut maka dilakukan suatu penelitian tentang deteksi isyarat tangan. Inputan berupa isyarat dan gerakan tangan didepan kamera dapat memberikan aksi pergerakan pada mouse yang diistilahkan dengan kamera mouse. Metode yang digunakan adalah convexhull algorithm. Melalui convexhull algorithm bisa didapatkan jumlah jari tangan yang kemudian dapat dijadikan acuan dalam pengerjaan aksi mouse. Sebenarnya sudah banyak penelitian tentang camera mouse, tetapi implementasinya masih banyak yang bergantung dengan peralatan tambahan. Penelitian ini mengembangkan penelitian yang sudah ada, yaitu hand gesture recognition dengan implemen-tasi pergerakan mouse dari video secara realtime. Dengan hand gesture recognition dan menggunakan metode convexhull algorithm pengenalan tangan akan lebih mudah hanya dengan menggunakan kamera, hanya dengan hitungan detik aksi mouse pada komputer dapat berjalan dengan baik yaitu dengan tingkat akurasi sebesar 68 % dari 75 kali percobaan
