Arguments are given in favor of creating a cryobank to preserve the reproductive material of military personnel. Fertility, or the ability to bear children, can be impaired by many detrimental factors associated with the conditions or place of service. In the Russian Federation, over the past few years, the rate of natural population decline has exceeded that of population growth, which has created a demographic void. According to the national concept of the demographic policy of the Russian Federation, by 2025 the population should reach 142143 million people, due to an increase in the overall birth rate, as well as the birth of a second child and subsequent children in families. However, sociological and statistical studies show that the adopted packages of measures are not yet affecting the birth rate, and with a simultaneous increase in mortality, the population continues to decrease. An important medical and social problem is infertility in marriage; in Russia its frequency is 15%17% of the total number of families. The contribution of male infertility to the overall structure of familial infertility is 40%. Stress and negative external factors, which are especially pronounced in high-risk groups, can affect male fertility. Military service associated with negative factors, stress, and life- and health-threatening situations can affect the reproductive system and lead to a decrease in reproductive potential or the development of infertility in a soldier. Cryopreservation of ejaculate allows childbearing to be delayed with the help of assisted reproductive technologies and can give the family a chance to have a child, even if the man has completely lost fertility. The creation of a cryobank of reproductive material will make it possible to protect military personnel whose service is associated with risks to life and health. One of the key responsibilities of the state health care system is the protection of the health of its citizens, especially those at risk, and the possibility of childbearing significantly affects the growth and population of the country.
Modern view on the role of pattern-recognition receptors and signaling pathways in the development of innate immunity in viral infections

Published: July 2022

Features of organization and functioning of pattern-recognizing receptors and signaling pathways in induction of antiviral immune response are considered. The recognition of antigenic structures of the virus is carried out by pathogen-associated molecular patterns of innate immunity cells. These are Toll-like receptors, nucleotide-binding oligomerization domain-like receptors, lectin C-type receptors, and RIG-I-like receptors. The functioning of these receptor structures depends on protein molecules that provide activation signals. These are the adapter proteins of the primary response of myeloid differentiation 88, interleukin-1 receptor-associated kinase, nuclear factor-KB. Interactions of cellular proteins in the activation of signaling pathways are complex and receptor-ligand reactions can lead to different outcomes in a single cell, in most cases leading to a limitation of viral reproduction. An important obstacle to the effective recognition of viruses and the development of an adequate immune response is the close organization of viral antigens and receptor structures of the cell. The role of LGP2 protein molecules is associated with the peculiarities of the development of the immune response, which can be not only positive, but also negative regulators of the transmission of excitation signals from intracellular cytoplasmic helicase receptors. A number of viral proteins inhibit activation signals, which ultimately leads to various options for the development of the immune response. A special role belongs to the transmembrane protein of the endoplasmic reticulum, which increases the expression of interferon a stimulator of interferon genes that provide detection of deoxyribonucleic acid viruses. Maximum activation of this protein, ensures the effective development of a cellular antiviral immune response.

Authors: Semenova Natalya V. , Brichagina Anastasia S. , Nikitina Olga A. , Madaeva Irina M. , Kolesnikov Sergey I. , Kolesnikova Lyubov I.
Published: July 2022

BACKGROUND: Menopause is a risk factor for oxidative stress. Previous study results indicate the lipid peroxidation ethnospecificity, suggesting differences in the metabolism of different ethnic groups of women, associated with the oxidation of not only lipids but proteins and DNA.
AIM: To determine advanced oxidation protein products (AOPP), advanced glycation end products (AGEs), and DNA oxidative modification levels in the blood of Russian and Buryat peri- and postmenopausal women.
MATERIAL AND METHODS: The study involved 86 women of two ethnic groups Russians (n=52) and Buryats (n=34) aged 45 to 60 years with peri- and postmenopausal status, which participated as volunteers. The basis for the exclusion in this study was the use of hormone replacement therapy, antioxidant drugs, diseases of endocrine origin, exacerbation of chronic diseases, premature early menopause, and surgical menopause. The concentration of 8-hydroxy-2'-deoxyguanosine (ng/ml) and AGEs (ng/ml) was determined in blood serum by enzyme immunoassay. The content of AOPP (nmol/l) was determined in blood plasma using the photometric method.
RESULTS: An increase of AOPP levels in postmenopause as compared to perimenopause was found in women of both ethnic groups (36.90 [27.09; 42.72] and 19.80 [17.03; 23.78] in the Russian ethnic group (p 0.001) and 31.16 [29.45; 33.99] and 26.30 [23.44; 30.91] in the Buryat ethnic group (p=0.020). Regardless of the menopausal phase, the AGEs levels in Buryat women were higher than the Russian ethnic group: (5015.0 [4584.49; 5486.96] and 3685.87 [3376.11; 4318.0] in perimenopause (p=0.002) and 4970 [4710; 5660] and 4274.59 [3440.67; 4813.05] in postmenopause (p=0.040)) and 8-hydroxy-2'-deoxyguanosine (1.58 [0.66; 4.36] and 0.82 [0.42; 1.09] in perimenopause (p=0.032) and 1.52 [1.06; 4.21] and 0.85 [0.49; 1.34] in postmenopause (p=0.018)). Differences in the AOPP level were revealed only in the perimenopause toward a higher level in Buryat women.
CONCLUSION: Protein oxidation depends on the menopausal phase and is more pronounced in postmenopausal women. The carbonyl stress parameters and DNA destruction levels are higher in Buryat women than Russian ethnic group.

Authors: Nagaeva Marina O. , Kolpakov Viktor V. , Oslina Alexandra N. , Tomilova Evgeniya A. , Bespalova Tatiana V.
Published: July 2022

BACKGROUND: It is crucial to organize a full-scale epidemic investigation into the rise in connective tissue dysplasia (DCT) among populations in varying climatic zones. Connective tissue dysplasia encourages the emergence and progression of several pathological conditions that harm life quality and length.
AIM: To identify the prevalence and structure of undifferentiated DCT syndrome among teenagers in different climate zones of the Tyumen region.
METHODS: An observational study in the Tyumen region, the Khanty-Mansi Autonomous Okrug-Yugra, the Yamalo-Nenets Autonomous Okrug included 578 teenagers, males, and females main groups (12 and 15 years) from secondary schools and residential schools. The evaluation of phenotypic symptoms for undifferentiated connective tissue dysplasia syndrome was according to recommendations by the Russian medical therapists society for diagnostics, treatment, and rehabilitation of people with DCT. The undifferentiated DCT syndrome has relevance, structure, and severity.
RESULTS: The amount of teenagers with undifferentiated DCT syndrome in the Tyumen region is 58.5%. The detection rate of undifferentiated DCT in the Tyumen region (south of the region) is 52.3%, in the Khanty-Mansi Autonomous Okrug-Yugra, it is 61.6%; in the Yamalo-Nenets Autonomous Okrug, 65.3%. Most of the registered phenotypic evidence of DCT included joint hypermobility, spinal scoliosis, hyperkyphosis of the thoracic spine, straight back syndrome, Varga index of 1.51.7, asthenic chest, bite anomalies, dysmorphism of the auricles, Gothic sky, loose and flabby skin, and myopia. A high average diagnostic coefficient, averaging 35.460.05 points, which surpasses the diagnostic threshold by more than two times and indicates possible complications of dysplastic changes. There are no differences in the severity of DCT manifestations according to several prognostically-significant criteria, depending on the climatic and geographical conditions within the studied area.
CONCLUSION: It is very important to take into account the high prevalence and severity of DCT among teenagers in the Tyumen region when planning programs for treatment, prophylactic, and rehabilitation measures.
Mechanically Drawing Polyacrylonitrile Nanofibers and Characterization of the Touchspinning Process
Authors:   , Coleman Brennan Finbar , Schauer Caroline L. , Li Christopher Y.
Published: July 2022

Polymeric nanofibers have been traditionally formed through the common electrospinning method. This method, while easy to run and efficient, includes dangerous drawbacks including the use of high voltage power supplies and the need for toxic polymer solvents. These drawbacks lead to further problems including limited mat collection and problems in processing complex natural polymers. Touchspinning is a brand-new method of nanofibrous mat formation. This method differs significantly from electrospinning in both its general set-up and the mechanism of fiber formation. The cold-drawing method of nanofiber formation by touchspinning utilizes a rotating disk with needles attached to it to "touch" a droplet of polymeric solution and pull this out, drying it in the process, to form a fiber. This process has been shown to be partially effective in biomedical application for neural stem cell proliferation, however the full analysis of its controllable parameters and their resultant fibers has not been conducted. Thus, the work presented here focuses on determining the full capabilities of the touchspinner to form nanofibers across varying controlled parameters and the parameters' effects on the final fibrous mat. The primary experiments explore the effects of polymer concentration, solution pump rate, and device rotation speed on both polymer nanofiber diameter and nanofibrous mat collection. Secondary results explore the further capabilities of the touchspinner to use complex and non-conductive substrates, demonstrate uninterrupted and significant collection rates, and evaluation of crystalline behavior within the nanofibrous mats. These results allow for a more full understanding of the touchspinning method and display the further capabilities of this method of polymer nanofiber fabrication.
Women's War: Media Representations of Female Civil Labour during World War I
Authors: Klein Reisa , Martin Michèle
Published: July 2022

This paper looks at the coverage of women’s civil labour during WWI in two magazines, Maclean’s in Canada and L’Illustration in France, supplemented with material from war museums and academic works. Our concern is media representations of the indispensible participation of these women, not as victims and passive entities in the conflict, but as individuals who have significantly contributed to the war effort. We contend that the magazines’ content did not reflect the magnitude of women’s civil labour during WWI and the importance they had not only in sustaining the war effort, maintaining a general level of production that would allow their countries to remain significantly involved in the war, but also in their contribution to the modernisation of society.
Les textos entre partenaires amoureux: un outil qui contribue à un meilleur déroulement des interactions en face-à-face ?
Authors: Schryer Benoît , Ross Philippe
Published: July 2022

Devant la disponibilité de multiples nouveaux canaux de communication, les partenaires amoureux valorisent particulièrement l’utilisation de la messagerie texte (ou textos) entre eux (Coyne et al., 2011; Pettigrew, 2009). L'usage des textos dans le cadre de relations amoureuses pose un problème intéressant eu égard aux comportements et aux attentes qui caractérisent ce type de relation. En effet, si le développement et le maintien des relations amoureuses reposent sur les interactions intimes (Andersen et al. 2006, p. 260) et la communication non-verbale qui les constituent (ibid; Frisby & Booth-Butterfield 2012, pp. 468-469), on peut se demander de quelle façon les textos – un moyen de communication a priori plus limité que la communication en face-à-face ou même le téléphone pour la transmission de signaux non verbaux – affectent les relations amoureuses. Le présent article cherche à faire la lumière sur la question à partir d'entretiens réalisés auprès de douze (12) jeunes couples amoureux. Les résultats suggèrent notamment que ces derniers utilisent les textos afin de préparer et minimiser l'incertitude qui peut caractériser leurs rencontres en face-àface.

Interpretation of Double Movement Theory in the Case of ‘The King Of Lip Service’
Authors: Syarif Zalfah Alin
Published: July 2022

Fazlur Rahman thinking, in the contemporary Islamic world, is known as a figure who is able to convince in formulating methods to understand the Qur'an. The method brought by Fazlur Rahman in the formulation lies in the study of philosophy, social science, and humanities. The method brought by Fazlur Rahman is often referred to as double movement hermeneutics or hermeneutika gerakan ganda. The process involves repeated movements a number of times, especially the present and past problems of the contents of the Qur'an. In this study, there are two problems, how is the statement of BEM UI on the coronation of President Joko Widodo as 'The King of Lip Service' and the relevance of this to the verse of the Qur'an about keeping promises in QS. Ali 'Imran verse 77. This type of research is a study of literature with a double movement theory approach to seeking substantive matters in the law of the Qur'an regarding keeping promises. The results of this study are that leaders who do not keep their promises and are tyrannical to their people have existed since ancient times, one of which was after the leadership of the Prophet Muhammad, for example, Al-Hakim Biamrillah Al-Fathimi. Even worse, nearing the end of the world, many unjust leaders will appear. The inclusion of President Joko Widodo as The King of Lip Service is a sign of dissatisfaction with Joko Widodo's words from reality.

Published: July 2022

This research focuses on two problem formulations concerning the practice of wa'a rai (elopement) carried out by the people of the Pota village and the factors that cause elopement, and the impact of elopement on domestic life. The research used descriptive and qualitative methods through field research. To facilitate the collection of data, facts, and information, the researcher will reveal and explain the problems in this study about how the impact of elopement on the household life of elopement actors after marriage in the Pota village community. Based on the analysis, it can be concluded that the practice of elopement in the Pota village community is allowed if it does not conflict with applicable law (Islamic Law and Law No. 4 of 1974). The elopement in the Pota village community is caused by internal and external factors. Internal factors include the absence of parental consent, mutual liking, and women having conceived out of wedlock. In contrast, external factors include Belis (dowry) and religious differences. The impacts of elopement in domestic life include economic or financial problems, triggering domestic violence, conflicts between daughter or son-in-law and parents-in-law, infidelity, and great opportunities for divorce.

Published: July 2022

Moral is the foundation of a person when behaving and carrying out his role in society. In today's digital era, we can see a lot of decline in the values and morals that used to be embraced by society. Advances in the digital field do not necessarily bring moral to a more advanced level, especially during this pandemic which also exacerbates moral decline. The lack of direct interaction during learning makes students indifferent to moral values. The decline in the "price" of morals in the eyes of society can be a big threat to the harmony of a society. Therefore, many actions need to be taken to patch and repair this damaged, faded, and abandoned moral, for example, through learning in Social Sciences (IPS) subjects in collaboration with parental education at home during distance learning. In this article, the author discussed what can be done and what we can hope for to improve moral. The research applied mixed methods.

Published: July 2022

Introducción: en 2020, la Organización Mundial de la Salud (OMS) declaró la emergencia de salud pública por SARS-CoV-21; el 11 de marzo de 2020 se notificó la pandemia global por COVID-19 y el gobierno colombiano decretó para todas las ciudades el aislamiento preventivo obligatorio2. Para el mes de mayo, Cali reportó 1635 casos de COVID confirmados y 85 fallecidos por un virus con un 4,95% de letalidad3. Lo anterior influenció de forma importante las rutinas alimentarias de las familias durante el primer trimestre del periodo de confinamiento. Considerando que esta situación era atípica en el país, era necesario describir la percepción del comportamiento alimentario durante este primer trimestre de aislamiento preventivo obligatorio en la ciudad de Cali, considerando las normas de bioseguridad establecidas para el periodo mencionado. Objetivo: describir el comportamiento alimentario de 1814 familias en Cali durante el primer trimestre de aislamiento preventivo obligatorio. Metodología: estudio cuantitativo, descriptivo transversal, con técnica de encuesta. Se aplicó un instrumento virtual compuesto por 28 ítems, que indagó el comportamiento alimentario de las familias. Discusión: se encontró que el 95,1% de los hogares percibió escasez y aumento de precios en alimentos que componen la canasta alimentaria familiar, y el 67,2% de las familias estuvieron preocupadas por la alimentación. Hubo un aumento en el consumo de alimentos y se modificó el número de tiempos de comida/día. Los hábitos alimentarios, ingesta de refrescos y consumo de alcohol también se modificaron durante confinamiento. Conclusiones: se puede afirmar que durante el primer trimestre de cuarentena por COVID-19 en Cali se modificó el comportamiento alimentario de las familias encuestadas, una de las razones estuvo relacionada con un cambio en los ingresos económicos, que afectó la cantidad de dinero disponible para alimentos. Durante este periodo se modificaron también los tiempos de comida y la variedad en la ingesta de alimentos. En general, se describieron aspectos que afectaron la seguridad alimentaria de las familias.

Published: July 2022

Introducción: las lesiones en el hogar constituyen una problemática importante para la salud pública. Más de la mitad de los niños sufre algún tipo de lesión, las más comunes son las caídas. El bajo nivel de conocimiento sobre lesiones de los padres y cuidadores está relacionado con factores personales y sociales y puede tener consecuencias negativas en los menores. Objetivo: identificar los factores relacionados con la prevalencia de conocimientos de cuidadores de menores de 5 años con respecto a lesiones en el hogar en la ciudad de Cali, Colombia. Metodología: este estudio se realizó en comunas de estratos socioeconómicos bajos y medio-bajos de Cali-Colombia. Participaron 519 madres y cuidadores. Se incluyeron variables sociodemográficas y se construyó la variable número de conocimientos adecuados frente a lesiones en el hogar. Se realizó un análisis descriptivo, se calculó la prevalencia de conocimientos de los cuidadores frente a las lesiones en el hogar y se construyó un modelo múltiple binomial negativo. Resultados: se encontró que los conocimientos de cuidadores de menores de 5 años con respecto a lesiones en el hogar están explicados por la edad del cuidador (p = 0,010 - coeficiente de regresión (β) 0,110 / p = 0,049 - coeficiente de regresión (β) 0,080) y el tipo de vivienda (p = 0,029 - coeficiente de regresión (β) 0,099). Discusión y conclusiones: la problemática sobre las lesiones en el hogar en menores de 5 años se debe al alto desconocimiento de la población en especial de aquellos que cumplen el rol de cuidadores.
Intelligent and Robust Controller Tuned with WOA: Applied for the Inverted Pendulum
Authors: Mourad Achouri , Zennir Youce , Tolba Cherif
Published: July 2022

Inverted pendulum is a well-known problem in the control theory because several systems such as robot balancing, Segway, hover board riding and operation of a rocket propeller are inherently based on Inverted Pendulum, furthermore it possesses a height non-linear and unstable dynamics. The main objective of our study is to introduce a comparative analysis of fuzzy logic (FLC), radial basis function neural network (RBF) and integral sliding mode control (ISMC) tuned with whale optimizer algorithm (WOA) for the control of the angle position and velocity of the inverted pendulum system. The implemented controller schemas can adequately reflect and approximate a certain type of uncertainties, nevertheless their parameters should be fine-tuned in order to get height and efficient performance, therefore all the antecedents and consequences of those controllers were tuned with WOA. This later provide height accuracy and fast convergence with height dimensional cost function. Comparative results shows that ISMC-WOA outperforms other techniques in term of settling time and overshoot.

Published: July 2022

Due to a combination of optimal properties such as great strength, high hardness, good process ability, and good mechanical properties, AISI 4340 steel is widely used in many critical industrial applications such as nuclear, military, defense, and aerospace. It is also widely used in hydraulic forged machine tools, forged automotive crankshaft systems, shafts and gears, because of their improved characteristics, and its good tribological properties. The purpose regarding this work is to check the tribological characteristics of austempered AISI 4340 steel while dry and lubricated with machinery oil of SAE 30 grade as base oil. As received, AISI 4340 steel samples have been austempered to four definitely austenitic phase temperatures (850℃, 900℃, 1000℃, and 1050℃) for 90 minutes before being immersed in a mixture of potassium nitrite and sodium nitrite at 400℃ for 45 minutes. Friction and wear tests were then performed on austempered samples. Multi-walled carbon nanotube particles were blended at weight concentrations of 0.055, 0.1, 0.15, 0.20, 0.25, 0.30, 0.35, 0.40, and 0.45 with typical machinery oil of 30 grade as base lubricant oil. A pin on the disc wear configuration was used in the experimental investigation. The use of Multi-Walled Carbon Nanotube (MWCNTs) additives in the base oil resulted in a decrease in both friction coefficients and wear rates values when compared to typical base oil lubricant. The results also showed a reduction in both friction coefficients and wear rates as the sample's austempering temperatures were raised. Sliding surfaces were also photo micro graphed, and when the volume concentrations of Multi-Walled Carbon Nanotube particles in the normal base oil lubricant were increased, smoother surfaces with less damage were shown.

Caracterização Das Forças Eletromagnéticas em Motor Linear Projetado para o Veículo MagLev-Cobra
Authors: Oliveira Roberto A. H. , Costa Felipe , Stephan Richard M. , Costa Paulo R. da , Ferreira Antônio C.
Published: July 2022

A obtenção da característica de força x velocidade de um Motor Linear de Indução projetado para veículos de transporte apresenta dificuldade pelo fato do secundário do motor se estender por um percurso longo, não estando confinado a um pequeno espaço, como é o caso dos Motores Rotativos ou mesmo dos Motores Lineares para aplicações em indústrias. Para contornar esta dificuldade, alguns métodos experimentais, com movimento confinado, foram propostos, por exemplo: motores cilíndricos com remoção de alguns polos do primário; bancadas de laboratório nas quais o deslocamento linear é substituído por um disco ou um tambor em rotação e, também, na forma de uma esteira plana em movimento fechado. No caso específico de veículos de Levitação Magnética (MagLev), um problema adicional advém da necessidade de garantir a levitação durante os testes. Isto costuma ser contornado com o uso de rodas de apoio bem lubrificadas, mas, mesmo assim, as medidas de força de tração sofrem com erros introduzidos pelo atrito. Além do mais, a medição da força de atração entre primário e secundário do motor linear apoiado em rodas exige uma adaptação engenhosa na instalação de extensômetros. No presente artigo, descreve-se a realização de um teste de laboratório para comprovar estudos de simulação e de testes com operação confinada de movimento de um Motor Linear para veículos MagLev. Trata-se de um simples procedimento estático, porém capaz de considerar a situação peculiar de um veículo sem contato com o solo na sua real situação de operação. Se a medição da força de tração possui limitação oriunda da baixa frequência de alimentação, compensada apenas com um incremento na razão V/f, em contrapartida, a força de atração entre primário e secundário, extremamente importante em veículos MagLev, revela-se de forma confiável. O método aqui apresentado mostrou-se suficientemente preciso para a escolha do Motor Linear de um veículo de levitação magnética para transporte urbano denominado MagLev-Cobra.

The basics of the electrocardiosignals informational analysis are outlined and the developments based on it are indicated. A block diagram of the electroseismic cardio unit is presented, the features of its design and functionality are indicated. The studied biophysical signals are listed and their properties are noted. The choice of parameters for the primary processing of biophysical signals is substantiated and a method for their calculation is proposed. It has been established that in the time domain it is rational to use such parameters of cardiocycles as amplitude, period and area. The results of experiments conducted on a group of patients are presented in order to identify the most revealing parameters of cardiocycles. Methods for visualization and evaluation of cardiocycle variability based on the Takens phase are proposed. It was found that on the phase plane the points corresponding to the periods of cardiocycles are approximated using an ellipse. It was determined that the most indicative parameters of the ellipse, reflecting the variability of cardiocycles, are the area, semi-minor axis and perimeter.

Materials and methods: This observational study included 74 patients with solid malignancies, mostly gastrointestinal. Prior to polychemotherapy, all patients were examined for endothelial function of small and large arteries (AngioScan-01, Fiton, Russia) and peripheral artery stiffness (pulse wave contour analysis and occlusion test). The results were compared with those of the Russian population trials of endothelial dysfunction – Meridian-RO (Ryazan region) and trial in the rural population of the Krasnodar region.
Results: Compromised vasodilation and smaller arteries tone were found in 64.9% (48/74) of the cancer patients, while impaired vasodilation of larger muscular arteries was present in 94.6% (70/74) of the patients. According to the Meridian-RO trial in the Ryazan region, endothelial dysfunction had been found in 51.2% (n = 341) of women and 52.4% (n = 300) of men, whereas the Krasnodar regional population data had shown it in 68.4% (n = 353) of women and 71.7% (n = 253) of men.
Conclusion: The prevalence of endothelial dysfunction in the patients with solid malignancies, who have not undergone any chemo- or radiation therapy, is significantly higher than in the population of comparable age, conventional cardiovascular risk factors, and comorbidities. No significant increase of vascular stiffness was identified.

Background: Yoghurt is a widely consumed dairy product all over the world. It has been used as an apt fortification and nutrient delivery medium in recent years. Methods: The present study aimed to assess the suitability of zinc oxide (ZnO) nanoparticle as a potential source of fortification of zinc in yoghurt. Three different levels of ZnO nanoparticles, as well as micro-sized ZnO, were added in yoghurt. Physicochemical, sensory, microbiological, rheological and textural characteristics of yoghurt were determined during 7 days of storage at 7±1°C. Result: Significant differences in physicochemical properties were observed in yoghurt samples during storage. All the yoghurt samples showed non-Newtonian characteristics. Zinc oxide nanoparticle added @ 75 ppm was found best for yoghurt fortification and showed advantages over fortification with conventional micro-sized ZnO. In this study, the effects of fortification of yoghurt with zinc oxide nanoparticle during storage were investigated. The FFA content of yoghurt was found to be 0.46% oleic acid and the Peroxide Value was found to be 0.32 Milli equivalent/kg fat, which was found to increase during storage. The tyrosine value at zero day was found to be 2.2 mg/g. The LAB count was 10.59 log10 CFU/g. Plastic viscosity of yoghurt was found to be 10.8.3 cP. Fortification of yoghurt with zinc oxide nanoparticle proved to be advantageous over fortification with micro-sized zinc oxide in terms of physico-chemical, microbiological, rheological and textural characteristics. Fortification of yoghurt with zinc oxide nanoparticle proved to be highly promising for zinc enrichment in the food system.

Background: The use of probiotics in aquaculture is increasingly acknowledged, thanks to rising demand for environment friendly aquaculture. However, there is an obvious need to improve our understanding of gut microbiology, as well as the effective preparation and safety assessment of probiotics.
Methods: The experiment comprised of five treatments to evaluate the influence of probiotic on water quality, growth and body composition. L. plantarum probiotic was sprayed over test diets at various concentrations @ 106 to 109 CFU/g, (D0 to D4 respectively). Water quality parameters were analysed (APHA, 2012) and growth parameters formulae (Halver, 1957) whereas fish feed and fish flesh nutritional composition, were measured (AOAC, 2012).
Result: All of the water quality parameters were within acceptable limits. Net weight gain (NWG), NWG %, specific growth rate, Condition factor and survival rate were significantly (P less than 0.05) highest in D4 and lowest in D0. Similarly, Feed conversion ratio and protein efficiency ratio also improved significantly (P less than 0.05). Moreover, there was a considerable rise in crude protein and lipid content in D4. In general, supplementation of L. plantarum @ 109cfu/g diet improved growth, survival and nutritional composition of Cirrhinus mrigala.
