The objective of this study was to evaluate the interaction of nitrogen and phosphorus fertilization and irrigation with saline water on the absolute and relative growth of West Indian cherry plant in vegetative phase. The research was carried out in protected environment, using lysimeters filled with clay loam Regolithic Neosol, with low P content. The experiment was set up in randomized block design arranged in a factorial scheme with five levels of irrigation water electrical conductivity (0.6; 1.4; 2.2; 3.0 and 3.8 dS m-1) and four managements of P and N fertilization – P/N (100:100; 140:100; 100:140 and 140:140% P/N) with three replicates and one plant per plot. Seedlings of West Indian cherry, cultivars BRS 366-Jaburu, was cleft-grafted on a local rootstock cultivar, from the Seed Garden of EMBRAPA Tropical Agroindustry. The plants were evaluated for absolute and relative growth of the rootstock and graft. The results showed that 40% increase in nitrogen and/or phosphorus supply can increase growth, chlorophyll content and reduced salt stress damage due to saline water in plants up to ECw = 3.0 dS m-1. The combined increase in nitrogen and phosphorus doses, 140:140% P/N, reduced the deleterious effects of saline stress on growth, chloroplastin pigments and membrane damage of the leaf cells of the West Indian cherry plants.

Published: September 2019

The information on behavior of crop linked to defoliation is essential to determine the management of herbivore pests. The aim of this study was to evaluate the performance of cassava as a function of the time and level of defoliation applied in the second cycle of cultivation, that is, after the first year of cultivation in which the crop was naturally submitted to the physiological rest period, caused by low temperatures and pluviometric precipitation typical of the southern Brazilian region. We used a randomized block design in factorial 5 x 5.in which 5 levels of defoliation (0, 25, 50, 75 or 100% of defoliation) were applied at 5 different times of 45, 90, 135, 180, or 225 days after sprouting (DAS) of the stems. The following variables were measured: plant height, stem diameter, number of roots per plant, root mass and amount of starch in the roots. The means were submitted to the F test at 5% of probability and analyzed by the regression test using the Sisvar software. Plant height and diameter were inversely proportional to the degree of defoliation when subjected to treatments, especially when subjected to 100% defoliation at 90 DAS. For the root mass, the more drastic defoliation treatments (100 %), when applied at 132 DAS, led to a low production, whereas only the defoliation levels induced a meaningful reduction in the deposition of starch in roots, showing a linear effect and decreasing according to the increase in defoliation. It can be concluded that defoliation between 90 and 135 DAS at the more drastic levels resulted in a greater root mass loss, regardless of the time of defoliation, caused the greatest losses in the amount of starch, therefore, it is recommended to the producer to control this pest before the 90 days of sprouting of the stems at the beginning of the defoliation.
A framework for cost-benefit assessment of alternative sediment management strategies in Dez hydropower reservoir: A probabilistic approach
Authors: Khakzad Hamid
Published: September 2019

A new theoretical approach to assessing the economic feasibility of sediment management strategies is proposed by incorporating probability distribution directly into the analysis. This would allow the life of Dez hydropower, for instance, to be prolonged definitely. The discount rate is also examined as a fundamental means of reflecting risk in discounted cash flow evaluations. Eight options for sediment management in Dez reservoir are assessed and future reservoir storage volumes estimated for the period 2018 to 2068. As a second step, discounted cash flow (DCF) with gamma discounting rate is used to evaluate present values for future cash flows for each option. The results indicate that these models, which offer an efficient approach, can be used to assess the cost-benefit feasibility of sediment management strategies. Guidelines are given for applying this approach to other projects.
Risk analysis of floodwater resources utilization along water diversion project: a case study of the Eastern Route of the South-to-North Water Diversion Project in China
Authors: Fang Guohua , Zhu Xiaohua , Huang Xianfeng
Published: September 2019

Based on fuzzy mathematics, a risk assessment model of floodwater resources utilization in a water diversion project was established based on the fuzzy network analytic hierarchy process (F-AHP). First, the weight of each factor was determined through AHP, and then the fuzzy evaluation method (FEM) was used for analysis and comparison. Finally, the optimal decision scheme was determined. The model was applied to the Eastern Route of the South-to-North Water Diversion Project (SNWDP) for floodwater resources utilization risk assessment. The results show that the model can utilize the risk factors of floodwater resources for identification and sorting, and then make a risk evaluation. The risk of floodwater resources utilization in a normal flow year is the lowest and the benefit is remarkable, providing a reasonable control scheme, and reducing unnecessary losses for the risk of floodwater resources utilization.

NMR Assisted Antimicrobial Peptide Designing: Structure Based Modifications and Functional Correlation of a Designed Peptide VG16KRKP
Authors: Biswas Karishma , Ilyas Humaira , Datta Aritreyee , Bhunia Anirban
Published: September 2019

Antimicrobial Peptides (AMPs), within their realm incorporate a diverse group of structurally
and functionally varied peptides, playing crucial roles in innate immunity. Over the last few decades,
the field of AMP has seen a huge upsurge, mainly owing to the generation of the so-called drug
resistant ‘superbugs’ as well as limitations associated with the existing antimicrobial agents. Due to
their resilient biological properties, AMPs can very well form the sustainable alternative for nextgeneration
therapeutic agents. Certain drawbacks associated with existing AMPs are, however, issues
of major concern, circumventing which are imperative. These limitations mainly include proteolytic
cleavage and hence poor stability inside the biological systems, reduced activity due to inadequate interaction
with the microbial membrane, and ineffectiveness because of inappropriate delivery among
others. In this context, the application of naturally occurring AMPs as an efficient prototype for generating
various synthetic and designed counterparts has evolved as a new avenue in peptide-based therapy.
Such designing approaches help to overcome the drawbacks of the parent AMPs while retaining
the inherent activity. In this review, we summarize some of the basic NMR structure based approaches
and techniques which aid in improving the activity of AMPs, using the example of a 16-residue dengue
virus fusion protein derived peptide, VG16KRKP. Using first principle based designing technique and
high resolution NMR-based structure characterization we validate different types of modifications of
VG16KRKP, highlighting key motifs, which optimize its activity. The approaches and designing techniques
presented can support our peers in their drug development work.
Skin Ageing: Pathophysiology and Current Market Treatment Approaches
Authors: Chaudhary Manupriya , Khan Azmi , Gupta Madhu
Published: September 2019

:

Ageing is a natural phenomenon which is a fold, ridge and crease in the skin that occurs
due to loss of body mass, poor hydration, disintegration of dermis and epidermis junction. The Skin
ageing process involves many changes that occur due to the combination of both endogenous factors
(gene mutation, cellular metabolism, and hormonal factor) and exogenous factors (U.V, pollutants,
chemical, and toxins). In 1950, the number of older people were found to be almost 205 million
across the globe. But this number almost got 4 times by the year 2012 and the number of older
persons increased to a massive amount of 810 million. The ageing of the skin occurs due to various
mechanisms like glycation, free radical, cell cycle, and cellular and molecular mechanism of skin
ageing. In this review article, we have discussed the treatment, worldwide newer therapies and
marketed formulation that are currently available for the reduction of skin ageing. The most promising
and revolutionizing field of nanotechnology is mostly applied in the field of dermatology,
cosmetics, and biomedical applications. Nanotechnology also plays a vital role in increasing the efficacy
of the product.

Authors: Gan Kwang-Chun , Sim Kooi-Mow , Lim Tuck-Meng , Teo Kah-Cheng
Published: September 2019

Twelve new 1,2,4-triazole Schiff bases bearing a fluorinated indole ring were successfully
synthesized. The 1,2,4-triazole Schiff bases were synthesized from the condensation reaction of
4-amino-5-mercapto-3-[(5-fluoro-2-methyl-1H-indol-3-yl)methyl]-1,2,4-triazole with a series of benzaldehyde
derivatives in the presence of (+)-tartaric acid as the catalyst. The structures of Schiff bases
were elucidated by FTIR, NMR and mass spectral data. All newly synthesized Schiff bases were
screened for their cytotoxic, antibacterial and free radical scavenging activities. Schiff bases 6b, 6c, 6i
and 6j with hydroxyl group at ortho or meta position of the phenyl ring demonstrated higher cytotoxic
activity against COLO-205 cell lines with IC50 94.0-144.3 µmol/mL. Schiff base bearing 2-OH and
5-Cl groups showed moderate antibacterial activity against Bacillus cereus at MIC 151 µmol/mL. On
the other hand, compounds 6b (IC50 150.4 µmol/mL), 6e (IC50 146.4 µmol/mL), 6f (IC50 120.9
µmol/mL) and 6g (IC50 146.2 µmol/mL) displayed a better free radical scavenging activity than the
standard BHT.
Is Rheumatoid Arthritis a Risk Factor for Fractures: A Systematic Review of Observational Studies
Authors: Gupta Ambika , Pipe Stephanie G. , Towheed Tanveer , Anastassiades Tassos
Published: September 2019

Aim:

The primary objective was to assess the risk of fractures in adults with RA compared
with controls from the general population. The review also assessed an increased risk of fractures
in RA patients when accounting for steroid use, RA disease severity or functional impairment.

Method:

Citations were screened from MEDLINE, EMBASE, Cochrane Database of Systematic
Reviews and CINAHL. Included citations were written in English, including adult patients at least
18 years of age and compared fracture incidence or prevalence between RA patients and a control
group. Case-control, cohort and cross-sectional studies were included.

Results:

There were a total of 3451 citations; after application of the inclusion criteria, 17 studies
were selected. In 14 of the 17 studies, there was an increase in the risk of fracture in RA patients
compared to controls. In studies that evaluated for glucocorticoid use, four of 13 demonstrated an
increased risk of fracture with glucocorticoid use, however, only two of these four studies specifically
assessed glucocorticoid use amongst patients with RA. In studies that analyzed RA severity or
functional impairment, two of seven demonstrated disease severity or impairment as a risk factor
for fracture. There was marked study heterogeneity in terms of patient and fracture characteristics,
which was a limitation of the analysis that impeded the ability to make direct comparisons.

Conclusion:

The risk of fracture in RA patients is elevated when compared to the general population,
although the etiology of the increased risk remains to be elucidated.
The Impact of Funding Insulin Research on Open Access Publishing: A 20-Years Bibliometric Analysis
Authors: Abbasi Hiba , Abu-Farsakh Noor , Abuazzam Farah , Halaseh Rasha , Alaraj Othman , Hassan Eman , Al-Essa Mohammad , AlRyalat Saif A.
Published: September 2019

Background::

The recent report of The World Health Organization on diabetes has stressed
on the burden of diabetes on low/middle income countries. Recent studies advocated the importance of
funding more research on diabetes and insulin in these countries. Recently, the European Research
Council advocated the importance of gold Open Access (OA) publishing, where the funded research
should be immediately accessible. In this study, we aim to assess funding for insulin research, where
we will compare the OA status between funded and unfunded research.

Methods::

We used Scopus database to assess insulin research published from January 1st, 1999 to December
31st, 2018. Our bibliometric analysis consisted of three main sections: analysis of all publications
on insulin, analysis of funded insulin publications, and analysis of unfunded insulin publications.

Results::

We found a total of 388,202 publications, of which only 83,180 (21.4%) were funded. USA
produced around 30.1% of the total publications, and the National Institute of Health (NIH) was the
major funder with 18.6% of all publications. Of the funded publications, 29,143 (35%) were OA publications,
compared to 97,347 (31.9%) of the unfunded publications. We didn’t find a significant difference
in OA status between funded and unfunded research.

Conclusion::

In concordance with the European Research Council’s decision to support gold OA publishing
model, we found that only 35% of the funded and 31.9% of the unfunded insulin research were
OA. Although the funded research is increasing in China, most of it is produced in high income countries.
This highlights the importance of allocating more funds to low/middle income countries.

Published: September 2019

Background:

Bone Age Assessment (BAA) refers to a clinical procedure that aims to
identify a discrepancy between biological and chronological age of an individual by assessing the
bone age growth. Currently, there are two main methods of executing BAA which are known as
Greulich-Pyle and Tanner-Whitehouse techniques. Both techniques involve a manual and
qualitative assessment of hand and wrist radiographs, resulting in intra and inter-operator variability
accuracy and time-consuming. An automatic segmentation can be applied to the radiographs,
providing the physician with more accurate delineation of the carpal bone and accurate quantitative
analysis.

Methods:

In this study, we proposed an image feature extraction technique based on image segmentation
with the fully convolutional neural network with eight stride pixel (FCN-8). A total of
290 radiographic images including both female and the male subject of age ranging from 0 to 18
were manually segmented and trained using FCN-8.

Results and Conclusion:

The results exhibit a high training accuracy value of 99.68% and a loss
rate of 0.008619 for 50 epochs of training. The experiments compared 58 images against the gold
standard ground truth images. The accuracy of our fully automated segmentation technique is 0.78
± 0.06, 1.56 ±0.30 mm and 98.02% in terms of Dice Coefficient, Hausdorff Distance, and overall
qualitative carpal recognition accuracy, respectively.

Published: September 2019

Objectives::

The present study was designed to investigate the effects of renin angiotensin system (RAS) blockade on cardiac arrhythmias and sympathetic nerve remodelling in heart tissues of type 2 diabetic rats.

Methods::

Thirty-two male Sprague Dawley rats were randomly allocated into 4 equal groups; a) normal control group: normal rats, b) DM group; after type 2 diabetes induction, rats received 2ml oral saline daily for 4 weeks, c) DM+ ACEi: after type 2 diabetes induction, rats were treated with enalapril (10 mg/kg, orally for 4 weeks) and d) DM+ ARBs: after type 2 diabetes induction, rats were treated with losartan (30 mg/kg, orally for 4 weeks).

Results::

In type 2 diabetic rats, the results demonstrated significant prolongation in Q-T interval and elevation of blood sugar, HOMA-IR index, TC, TGs, LDL, serum CK-MB, myocardial damage, myocardial MDA, myocardial norepinephrine and tyrosine hydroxylase (TH) density with significant reduction in serum HDL, serum insulin and myocardial GSH and CAT. On the other hand, blockade of RAS at the level of either ACE by enalapril or angiotensin (Ag) receptors by losartan resulted in significant improvement in ECG parameters (Q-T), cardiac enzymes (CK-MB), cardiac morphology, myocardial oxidative stress (low MDA, high CAT and GSH) and myocardial TH density.

Conclusions::

RAS plays a role in the cardiac sympathetic nerve sprouting and cardiac arrhythmias induced by type 2 DM and its blockade might have a cardioprotective effect via attenuation of sympathetic nerve fibres remodelling, myocardial norepinephrine contents and oxidative stress.
Recent Patent on an Energy Conserved Journal Bearing with the Slippage Sleeve Surface
Authors: Zhang Yongbin , Chen Haijun
Published: September 2019

Background:

Energy consumption in mechanical apparatus has become a big problem in
modern industry. It is very important to develop energy-conserved rotary machines, which are very
promising in the future.

Objective:

To introduce a patented energy-conserved hydrodynamic journal bearing with low friction
where the interfacial slippage is designed on the whole sleeve surface.

Methods:

The analytical results are presented for the carried load and friction coefficient of the introduced
bearing based on the limiting interfacial shear strength model. The performance of the introduced
bearing is compared with that of the conventional hydrodynamic journal bearing for the
same operating condition.

Results:

The obtained results show that in the same operating condition, the carried load of the introduced
bearing can be 35%~50% times that of the conventional journal bearing, but its friction
coefficient on the shaft surface can be 30%~70% times that of the conventional journal bearing,
while its friction coefficient on the sleeve surface is considerably lower and can only be 5%~20%
times that of the conventional journal bearing. The friction reducing effect of the bearing depends
on the eccentricity ratio and the fluid-sleeve surface interfacial shear strength; the lower the latter,
the smaller the friction coefficients on both the shaft and sleeve surfaces.

Conclusion:

The introduced bearing is obviously of low friction and energy-conserved. It has application
values especially in the condition of modest eccentricity ratios, where the loss of the loadcarrying
capacity of the bearing due to the interfacial slippage is not so large.

Authors: Kumawat Priyanka , Sharma Rashmi , Sharma Arun K.
Published: September 2019

Background: The effective removal of heavy metals from aqueous wastes is among the
most important issues for many industrialized countries. Present paper reports about the synthesis
of copper neem urea complex (CNU) and its characterization using elemental and spectroscopic
techniques such as IR, NMR, and ESR.

Methods: The NPs of ZnO and doped with SiO2 which was extracted from industrial ash’s) was
synthesized by precipitation method and characterized through UV, SEM-EDX and XRD techniques.
Three low cost adsorbents such as synthetic ZnO, nano ZnO and doped ZnO with SiO2
were chosen for the adsorption of copper surfactant complex of urea from non-aqueous solutions
i.e. petroleum ether. Effect of various parameters like contact time, pH, adsorbent dosage, temperature
and initial metal concentration on the removal through degradation and adsorption of
CNU were investigated and optimized.

Results: Isothermal studies indicated that the adsorption of CNU followed Langmuir adsorption
isotherm. Kinetic studies indicated that removal of the CNU by the three adsorbents followed
second order kinetics. With a maximum adsorption capacity of 7.58 mg/g using all three adsorbents
showed an effective and efficient removal 95.8% of CNU from non-aqueous solutions by using
ZnO doped with SiO2 compare to synthetic ZnO and nano ZnO. This is the first report of removal
of the CNU complex based on the three adsorbents.

Conclusion: The potential of application for the treatment of solutions containing these complexes
in multi-metal solutions is indicated.

Published: September 2019

Background & Objective:

Plastics are strong, light weight and durable due to
which it has wide applications. Degradation of plastics is difficult due to their xenobiotic
origin and recalcitrant nature. Hence, accumulation of plastics in the environment is posing
an increasing ecological threat.

Methods:

Various methods are preferred for the reduction of plastics in the environment, of
which degradation by chemical and biological means are considered to be more effective. In
the biodegradation of plastics, micro organisms play a pivotal role. In the present work, microbial
species are isolated from different sources such as cooking oil, grease and petroleum
products. Two bacterial species such as Sphingomonas, Pseudomonas aeruginosa and three
fungal species such as Aspergillus niger, Aspergillus flavus and one unidentified fungal species
were isolated from the sources were used for the degradation of polyethylene plastic
samples (black and white).

Results:

Sphingomonas indicated 56% (black) and 31% (white) degradation of polyethylene
plastic. Unidentified fungal species also indicated 64% (black) and 45% (white) degradation
of polyethylene plastic. During the degradation, pH altered from 7 to 8. SEM analysis indicated
the presence of appreciable surface erosions, fading, cracks and extensive roughening
of the surface with pit formation.

Conclusion:

Sequence analysis of Sphinogomonas species was done in comparison with the
similar known bacterial species and the phylogenetic tree was generated based on the sequence
analysis.

Authors: Khazaee-Pool Maryam , Pashaei Tahereh , Ponnet Koen
Published: September 2019

BACKGROUND

Despite the first rank of breast cancer incidence diagnosed in Iranian women, they have one of the lowest rates of breast cancer preventive behaviors. So that these behaviors have not been applied as routine care for healthy Iranian women. To improve preventive behaviors, a reliable and practical approach is needed. This study aimed to develop and test the culturally tailored mobile Phone-based application to promote breast cancer preventive behaviors called ASSISTS among Iranian women.

OBJECTIVE

This study explores the impact of ASSISTS mobile application on changes to study Iranian women’ preventive behaviors toward breast cancer and recommends suggestions for how the intervention can be enhanced for varied dissemination and performance in the Iranian community.

METHODS

Applying a randomized controlled trial design, 140 Iranian women aged 40 years and above were recruited and randomly appointed to either the intervention group (n=70) to receive culturally and personally tailored multilevel messages by a smartphone application accompanied by the routine health care facilities and control group (n=70) to receive just a routine health care. Outcome measures included attitude, stimulus, self-efficacy, information seeking, stress management, self-care, and social support, readiness for performing breast cancer preventive behaviors. The feasibility and acceptability of the ASSISTS mobile application intervention were also assessed.

RESULTS

Significant intervention effects were observed for objectively measured knowledge and self-reported variables of ASSISTS scale (all P<.05). The intervention group indicated significantly more change on scores of knowledge of preventive behaviors procedures and self-care (P=.01). The ASSISTS app group indicated significantly more readiness for breast exams use after the intervention compared with the booklet group. Furthermore, the intervention group evaluated consent with the intervention (P=.001) and increase of knowledge on breast cancer preventive behaviors (P=.001) more significant than the booklet group. About 68.2% ASSISTS app participants assessed this app as self-explanatory (44/70), fun (64/70, 66.5%), and interesting (63/70, 88.8%).

CONCLUSIONS

An ASSISTS smartphone app-based intervention was a practical, useful, and suitable intervention means to improve breast cancer preventive behaviors in Iranian women. A flexible, directly tailored method that depends on current technical progress can gain underserved and hard-to-employee populations that bear unequal cancer loads.

El apoyo a estudiantes sobresalientes en la educación a distancia: una necesaria medida de equidad
Authors: Sánchez Mercado Sara Griselda
Published: September 2019

La reflexión plantea la necesidad de reconocer en el bachillerato a distancia a los estudiantes con capacidades sobresalientes cuyo proceso de formación, aunque evidentemente justificado por la búsqueda de equidad e igualdad de oportunidades educativas para todas las personas, se encuentra supeditado a las necesidades y circunstancias del grueso de la población escolar. La situación refleja injusticia para cada alumno singular y para su familia, mientras que para la sociedad en general supone una pérdida importante.
Se explora la posibilidad de inclusión de estrategias y acciones concretas, como la enseñanza individualizada y la adaptación del currículo para favorecer el desarrollo escolar de los estudiantes de alta capacidad en la educación media superior a distancia, planteamiento que pretende aportar al logro de una formación no sólo equitativa e inclusiva, sino motivadora y facilitadora del éxito académico para estos estudiantes.
Exploración del uso educativo de YouTube por parte de estudiantes de bachillerato
Authors: Bardakcı Salih
Published: September 2019

YouTube es una de las redes sociales predominantes en todo el mundo. Sin embargo, falta investigación sobre los factores que influyen en el uso educativo de YouTube. Este estudio examina el uso educativo de YouTube por parte de estudiantes de bachillerato con la Teoría unificada de aceptación y uso de la tecnología (UTAUT, por sus siglas en inglés). Con el uso de modelización de ecuaciones estructurales, se prueba el modelo propuesto. Los resultados demuestran que la expectativa de desempeño y la influencia social son factores predictivos significativos de la intención conductual del uso de YouTube. Más aún, la intención conductual constituye el predictor significativo del uso real. Los resultados sugieren que los estudiantes piensan usar YouTube para mejorar su rendimiento académico. La influencia social también contribuye a su intención. Se discuten los resultados con base en literatura previa.

Surveyed 652 patients with persistent violations of rhythm who applied to the cardiologist of the center of VMA during the 2 years. Of 652 patients was highlighted that some patients (543), in which the rhythm disturbance with daily monitoring Holter ECG were significant, that is, the number of ventricular and supraventricular extrasystoles exceeded the acceptable rate. These patients were divided into 3 groups to assess the frequency of ventricular and supraventricular arrhythmias: Group 1: patients with a primary rhythm disturbance according to the type of ventricular arrhythmia — 96 people (80 men and 16 women). Their average age was 68 years (18–89). Group 2: patients with a primary rhythm disturbance according to the type of supraventricular extrasystole — 343 (271 male and 72 female). Their average age was 67 years (17–83). Group 3: patients with complex arrhythmias (supraventricular and ventricular premature beats) — 106 patients (94 male and 12 female). Their average age was 65 years (18–87). Compulsory medical examination for the patient included a complete medical examination with the filling of a formalized medical history; laboratory studies (clinical blood analysis, biochemical blood — potassium, sodium, magnesium, chlorine, glucose, lipid spectrum, creatinine, total protein, coagulation profile, thyroid hormones T3, T4, TTG); instrumental examinations (ECG, daily monitoring of Holter ECG, radiography of the chest, echocardiography). Identified possible etiologic factors in the occurrence of arrhythmias in patients. The main etiological factors of arrhythmia were: ischemic heart disease (IHD), arterial hypertension (AH), heart failure II–IV FC, the presence of sclerodermatineae acquired heart disease, cardiomyopathy, diabetes mellitus type II, thyroid disease (hyperthyroidism and hypothyroidism), cancer, history of pulmonary embolism (PE), acute violations of cerebral circulation (cerebral vascular accident), coronary artery bypass graft (CABG), family history of coronary heart disease, overweight, menopause. The main provoking factors according to the survey patients were: alcohol abuse and Smoking, daily repeated use of strong tea and coffee, psycho-emotional and physical stress, infectious diseases.48 surveyed (8,84%) did not identify any apparent cause arrhythmias. This group of patients underwent heart MRI for the purpose of clarifying the nature of the arrhythmias. In 32 patients performing MRI of the heart has allowed to establish probable cause rhythm disturbances, draws attention to the high frequency of detection of MR-signs of myocarditis (1⁄3 of the surveyed).

Introduction. The increasing maritime activities in Russia require more healthy marine professionals, which is the scope of marine medicine. Objective. To evaluate the influence of visual control on stabilometric parameters in healthy volunteers depending on gender and age. Examined: healthy volunteers in the «free» stand, at a standardized workplace: male, Group 1 (n=31, age 22,0±0,6 years); Group 2 (n=30, age 51,7±2,3 years); female: Group 3 (n=31, age 21,9±0,6 years); Group 4 (n=33, age 49,5±2,2 years). The following parameters have been studied: EllS, mm2; KoefRomb, %; LFS, 1/mm; the quality of equilibrium function — KFR, %; VFY; R, mm; deviation of the center of pressure on the frontal or sagittal planes — Q(x) and Q(y), mm; the coefficient of sharp change in the direction of movement — KRIND, % in the Romberg and Target tests. It has been established that with open eyes, the parameters almost do not depend on age and sex. In the «Target» test, EllS significantly increases only in men and women of the older age group, and with closed eyes, EllS is significantly lower in women than in men. With closed eyes, the KFR values of women in both groups are significantly higher as compared with the corresponding (same age) groups of men. The KFR index in the Target test is significantly higher in young women than in young men. With the vision «turned off», a significant backward shift of the center of gravity has been noticed only in men of the older age group (60,7%) as compared with the corresponding group of women (27,3%). With open eyes, only young men have a reliable maximum KRIND relative to other groups. Evaluation of stabilometric parameters without taking into account the age, sex, visual control can lead to false conclusions when comparing patients with healthy people. It has been found that the visual analyzer and its deprivation significantly affect the whole complex of postural control depending on gender and age.

The influence of mental states on the morbidity of military cadets was investigated. Surveyed 102 cadets 2–3 courses of the Naval Academy. N. G. Kuznetsova at the age of 18–23 years. In terms of incidence, the patients were divided into two groups: n=66 did not suffer during the year of study, n=36 had labor losses during the year from 3 to 25 days (10,06±6,1). For self-assessment of the mental state, a modified method of assessing the mental states of a person, proposed by A. O. Prokhorov. Mathematical modeling of the prediction of the incidence of cadets of a military university was performed using discriminant analysis. Comparative analysis was performed using student’s criterion. On the basis of discriminant modeling, a highly informative model for forecasting the incidence of military cadets’ cadets was developed. Predictors of incidence of military cadets are a combination of indicators of mental states: excitation, gaiety, ease, thoughtfulness, fear, laziness. At the same time, for cadets who have a disease during the year, laziness is typical, aspiration for entertainment and excitement, they are less at ease, more thoughtful, possibly inclined to self-analysis, analysis of their physical condition, critical to the environment. They do not experience a state of fear, and, perhaps, a sense of respect for the collective associated with it, since getting exemption from performing duties on a «non-serious» disease in the military collective is perceived as a desire to evade their duties and disdain for their colleagues. The application of the developed model of the prognosis of the incidence of cadets will make it possible to increase the effectiveness of measures for medical and psychological support of military personnel in military universities.
