PREDICTION OF MULTIPLE SCLEROSIS COURSE: RESULTS OF PROSPECTIVE STUDY
Authors: Shulga O.D.
Published: April 2020

Background: The course of multiple sclerosis is variable and unpredictable. Despite considerable efforts and research over the decades, one of the major challenges for both neurologists and patients is still to determine the prognosis of multiple sclerosis as well as the factors and markers affecting its progression. Prospective studies can partially contribute to assessment of the factors predetermining the prognosis of the course of multiple sclerosis.

Objective: To evaluate the factors affecting the course of multiple sclerosis according to a 5-year prospective dynamic observation.

Materials and methods: 175 patients with multiple sclerosis were examined over a 5-year follow-up period. The methodology employed was as follows: statistical analysis by using Microsoft Excel for Windows and SPSS; standard descriptive statistics; calculation of Pearson's chi-square for categorical analysis; single-factor analysis of variance. The magnitude and directivity of the correlation dependence were estimated using the Spearman non-parametric correlation coefficient.

Results: 175 patients with multiple sclerosis (123 women and 52 men) were examined over a 5-year follow-up period. Mean age of patients at the onset of multiple sclerosis was 28.46 ± 9.13 years; mean age at the time of diagnosis of the disease was 31.77 ± 9.28 years; the mean length of the disease was 15.48 ± 7.69 years prior the start of the observation. At the time of the patients’ status assessment in 2013, the Expanded Disability Status Scale value was 3.83 ± 1.68 scores and 4.21 ± 1.83 scores in 5 years. The degree of functional disability according to the Expanded Disability Status Scale baseline was statistically significant (p = 0.02). A single-factor analysis of variance showed that sex (p <0.007) was of the highest significance for the degree of difference by the Expanded Disability Status Scale.

Conclusions: According to results obtained, we can suggest the most influential factor for a patient's disability due to multiple sclerosis is sex. Men may develop multiple sclerosis at younger age, the disease in men progresses faster, thus, the degree of functional disability is higher compared with women.

The article presents the results obtained by testing the previously proposed physical and mathematical model of the temperature distribution in the layer of poured seeds when irradiated with a high-frequency electromagnetic field. It has been proven that temperature is one of the factors influencing the consequences of pre-sowing seed treatment. We have found out that, along with heating, other physical processes occur in the seed structure at the level of cell membranes and membrane transport of substances. The transformation of protein structures, the polarization of cell membranes, and the intensification of metabolic processes under the influence of irradiation can lead to changes in the electrical properties of seeds and, as a consequence, can impact on the physiological state, germinability and growth energy of plants. The result of the seed exposure to high-frequency electromagnetic field depends on the electrical characteristics of the seeds. We have developed a technology for the pre-sowing treatment of Echinacea and Valerian seeds in order to obtain more ecologically pure raw materials for pharmacological industry. The study has demonstrated positive thermal and oscillation effects produced by the electromagnetic field on the structural elements of seeds. Based on the method of presowing stimulation of the seeds with a high-frequency electromagnetic field, the optimal modes for irradiation of Echinacea and Valerian seeds have been elaborated. It has been established that boosting the overall resistance of biological tissue, an increase in the polarization of cell membranes indicates an enhancement of metabolic processes and, as a result, stimulates the process of seed germination and rapid vegetation in the early stages of plant development. Theoretical calculations and experimental studies have evidenced positive results doe to implementation of the described technology.

Authors: Brodetskyi I. S. , Malanchuk V.A. , Dosenko V. E
Published: April 2020

Introduction. Pleomorphic adenoma is known as the most common tumour in salivary glands that makes up 60-90% of all benign tumours of the salivary glands. The modern genetic tendency towards the diagnosis of salivary gland tumours is the study of the role of microRNA molecules, and miRNA-29a in the focus of the great researchers’ interest. It is expressed in 84 % of the pleomorphic adenomas of the salivary glands. Objectives. Determination of expression of miRNA-29a in tissues of pleomorphic adenomas of the large salivary glands that adjacent to the tumour of the tissue of the salivary gland, intact tissue of the salivary gland, was out of touch with the tumour and venous blood.  Materials and methods. The study included 20 patients with benign tumours of the large salivary glands (pleomorphic adenomas). The expression of miRNA-29a was evaluated by using reverse transcription and quantitative polymerase chain reaction (qPCR) in real time.

Results. The analysis of the level of miRNA-29a expression revealed that among 4 groups of indicators (tumour tissue, tissues adjacent to the tumour salivary gland tissue, intact salivary gland, which was out of touch with the tumour and venous blood) in patients with pleomorphic adenoma of the large salivary gland, the highest expression was noted in the group, where salivary gland tissue was adjacent to the salivary gland tumour (111, 93±56, 97 versus 8,12±4,4). Correlation analysis of patients with pleomorphic adenoma of the large salivary glands with different fragments of tissues samples demonstrated that the expression level of miRNA-29a differed significantly between the groups (adjacent gland - intact salivary tissue).

Conclusions. A sufficiently high level of miRNA-29a expression in the tissues of pleomorphic adenoma in the large salivary glands compared with the normal (intact salivary gland tissue), 10 times as much can be used as a genetic marker for verification (identification) of this type of tumours. Studies of biopsy material from patients with pleomorphic adenoma in the large salivary glands at the genetic level (by expression of miRNAs-29a) confirm the need not only in enucleating of the tumour (partial parotidectomy), but also in performing of subtotal resection with removal of salivary gland adjacent to the tumour.

The article presents the results of assessing the activity of catalase and superoxide dismutase enzymes in the blood as markers of the nephroprotective effect by sodium poly-(2,5-dihydroxyphenylen)-4-thiosulfate acid under conditions of ethylene glycol and glycerol acute kidney injury and gentamicin-induced nephropathy. The studies were conducted on 96 white mature, full-grown non-linear rats of both sexes weighting 180-200 grams. Models of acute kidney pathology in the rats were reproduced in accordance with the methodological recommendations of the Ministry of Health of Ukraine. Blood activity of superoxide dismutase and catalase was determined spectrophotometrically with standard methods. It has been established that oxidative stress plays a significant role in the pathogenesis of ethylene glycol and glycerol acute kidney damage and gentamicin nephropathy, as evidenced by significant changes in the antioxidant defence system, and namely by inhibition of the activity of superoxide dismutase and catalase enzymes. Under the conditions of acute kidney injury and nephropathy, the sodium poly-(2,5-dihydroxyphenylen)-4-thiosulfate acid contributed to the activation of superoxide dismutase and catalase better than reference medicines as plan-based chophytol, and mexidol as antihypoxant and thiotriazoline as antioxydant. Thus, the antioxidant enzymes as superoxide dismutase and catalase can serve as markers of the nephroprotective effect produced by the preparation of sodium poly-(2,5-dihydroxyphenylen)-4-thiosulfate acid. And therefore, we suggest sodium poly-(2,5-dihydroxyphenylen)-4-thiosulfate acid exhibiting antihypoxic, cytoprotective, antioxidant properties is a promising drug for the treatment of acute kidney diseases.

The article shows that not only the health of the nation, but also the future of the peoples throughout the world  and the future of the planet itself depends on the development of science and the quality of professional training of those providing the modern scientific process. The article highlights the stages of scientific anatomy, the results and prospects of its development. The goals, objectives, methods and results of our own research are identified on the basis of the stereomorphological method for studying hollow and parenchymal internal organs and glands. The article presents a unique technique that enables to obtain a three-dimensional view of the vessels of the human body, contributing to the spatial perception of the architectonics of the extra- and intraorgan blood channel, the injection-corrosion method, developed by the Dutch scientist F. Ruysch. It has been noted that the originality of the museum of the Department of Human Anatomy, Ukrainian Medical Dental Academy, is in its rich collection of injection and corrosion preparations of the internal organs of humans and animals. This classic technique, taking into account individual modifications, enables to get an accurate high-quality volumetric copy of the bloodstream of the internal organ or casts of the walls of a hollow organ, suitable for further morphological studies. Using the example of injection-corrosive preparations of the bloodstream of the human stomach, the features of its stereo-angioarchitectonics were investigated.

The article highlights the methodology for stereological study of the prostate, large and small salivary and lacrimal glands, used by the researchers of the Department of Human Anatomy, Ukrainian Medical Dental Academy. In particular, the results of three-dimensional plastic reconstruction have been described using the example of human epithelial structures of the prostate gland and small salivary, lacrimal glands.

Introduction. The algorithm for choosing a method of treatment for permanent teeth with incompletely formed root, described in the study of Shabahang S. (2013), involves the procedure of apexification in cases of irreversible pulpitis and pulp necrosis, and convalescent therapy in cases of diagnosis of recurrent pathological phenomena in the pulp structure. The aim of the study was to conduct a retrospective analysis of the effectiveness of applying mineral trioxide aggregate and calcium-containing agents in order to carry out the apexification procedure according to the data of previous studies. Materials and methods. Relevant publications were searched by Google Scholar search (https://scholar.google.com/), Pubmed databases (https://www.ncbi.nlm.nih.gov/ pubmed /) and ScienceDirect (https://www.sciencedirect.com/). Results. The data available to date are of varying evidence and do not confirm the fact that the mineral trioxide aggregate is more clinically effective than calcium hydroxide for the purpose of apexification in cases of endodontic treatment of incomplete root formation. However, a significant advantage of mineral trioxide aggregate is the possibility of one-stage root canal formation with subsequent permanent obturation of the root canal after complete curing of mineral trioxide aggregate. Conclusion. The reports analyzed are characterized by variability of designs and the use of different approaches to assess the formation of the apical part of the tooth; moreover, most publications do not evaluate the initial level of root formation, which can potentially affect the success of the manipulation. The lower success rate of calcium-containing aids for apexification reported in a number of studies is justified by the prolongation of treatment, during which there is a tendency for patients to miss the check-ups and to drop out of the generated study sample during the relevant monitoring period. In order to formulate appropriate clinical recommendations, it is necessary to ensure that the baseline and treatment outcomes are referenced to a unified system of criteria for interpretation of all quality indicators of apexification achieved.

Published: April 2020

The anatomical and physiological characteristics of a growing organism require a specific approach to the prevention and treatment of periodontal diseases. Not enough attention is paid toward improving the oral health of children suffering from diabetes mellitus, as well as therapeutic and prophylactic measures aimed at preserving teeth and preventing exacerbations of the inflammatory process in periodontal tissues. The results of clinical studies indicate a high prevalence of dental diseases in patients with type I diabetes mellitus; there are not enough reliable results of such indicators depending on the age and duration of this endocrine pathology, diabetic complications, hypoglycemic therapy taking into account metabolic control. Diagnosis of periodontal diseases is complicated by the peculiarities of the child’s psychological perception, caused by age-specific characteristics and the influence of common manifestations of inflammatory diseases. Children of primary school age often demonstrate increased motor activity, a hyperergic reaction even to minor negative feelings, the difficulty of adequate behaviour in an unfamiliar environment and a correct assessment of what is happening, being stressed due to the presence of many phobias associated with doctors and medical manipulations, communicative difficulties caused by staying in the spotlight, meeting new people, talking with adults. Teaching children must necessarily be accompanied by educating parents, since within limited time interval of dental appointment a doctor does not have the opportunity to fully monitor and consolidate the knowledge and skills the child has received, and this responsibility falls on parents. In this case, some attention should be paid to issues of skills, motivation as well as on the importance dental care aspects for the development of the dentofacial system, since in the vast majority of cases, parents are not enough aware on these issues. In addition to educating and fostering the motivation, it is necessary to control the level of knowledge, the frequency and quality of tooth brushing. For young children, it is necessary to do complete cleaning up the chewing group of teeth due to the low level of children’s manual skills.

Authors: Poda O.A.
Published: April 2020

Introduction. At present, antimicrobial therapy of ventilator-associated pneumonia and bacteremia caused by Pseudomonas aeruginosa is an urgent problem due to the high prevalence of microbial multiresistant strains and their ability to develop resistance to new antibacterial drugs.

Materials and methods. The analysis and generalization of the results of scientific studies highlighted in fundamental medical journals related to the treatment of ventilator-associated pneumonia and bacteremia caused by Pseudomonas infection are carried out.

Results. The main points in the modern approach to the effective treatment of ventilator-associated pneumonia and bacteremia caused by Pseudomonas aeruginosa include the correct empirical choice of the starting antibacterial agent in accordance with the local epidemiology of the medical setting, timely beginning of the treatment, options to combine drugs with a tendency to de-escalation to monotherapy. It is also important to choose the optimal drug in terms of its pharmacological parameters and a clear definition of the optimal therapeutic dosage. The article describes the main groups of drugs currently used in the treatment of the main clinical forms of Pseudomonas aeruginosa. Nowadays, it is recommended to combine therapy for pseudomonas ventilator-associated pneumonia and bacteremia with antipseudomonas penicillins or cephalosporins or carbapenems plus fluoroquinolones or aminoglycosides or colistin with phosphomycin.

Conclusions. Despite the elaboration of the modern approaches to the antimicrobial therapy of infections caused by Pseudomonas aeruginosa, this issue is still debatable and requires further study.

Systemic scleroderma is an autoimmune connective tissue disease with characteristic lesions of the skin, blood vessels, musculoskeletal system and internal organs (kidneys, heart, lungs, and digestive tract) based on impaired microcirculation, inflammation and generalized fibrosis. At the stage of provisional diagnosis, the triad of the initial signs of the disease is especially important including Raynaud’s syndrome, characteristic skin lesions, and joint syndrome. Subsequently, multiple organs and tissues are involved in the process. Infectious complications are one of the major threats to patients with systemic connective tissue disease, along with cardiovascular and cancerous diseases. Based on retrospective analysis, it has been found out that the incidence of comorbid infections in the in-patients with rheumatic diseases made up 9.7%; with predominant damage to respiratory organs was 44%, urinary tract – 29.2%, and skin and soft tissues – 18.9%. Comorbid infections were the most common in patients with systemic lupus erythematosus (28.4%) and rheumatoid arthritis (13.2%). Infections constitute 2-9% of overall causes of mortality in patients with systemic scleroderma. Cases of serious infections (pneumonia, sepsis, bacterial arthritis, skin and soft tissues lesions, etc.) have been recorded, including those with fatal outcomes. The problem of differential diagnosis of systemic infectious process and rheumatic diseases with high activity is extremely important. The paper presents a clinical case of subacute course of systemic scleroderma with multiple organ dysfunction affecting lungs (pneumofibrosis, pulmonary hypertension), heart (restrictive cardiomyopathy, atrial flutter), kidneys (nephritis) conjoined with severe infectious complications (septicemia, phlegmon of the soft tissues of the left leg). The present clinical case clearly demonstrates a severe subacute course with multiple organ dysfunction affecting lungs, heart, kidneys, digestive tract. Immunodeficiency was accompanied by severe infectious complications, in particularly, septicemia, soft tissue phlegmon, having complex pathogenesis that required prolonged intensive care.

The relevance of this research is determined by a number of factors including Chernobyl tragedy, enforced usage of computer technologies and telecommunication, environmental problems, unhealthy diet poor in poor in vegetables and fruits. This promotes the condition for increased free radical production by the body and antioxidant system emaciation. Alzheimer’s and Parkinson’s diseases, lateral amyotrophic sclerosis and cataract, stroke, brain and spine traumatic injuries have been reported as rapidly growing worldwide. Less common diseases with ethio-pathogenetic mechanisms mentioned above include peroxisomal biogenesis disorders (X-linked adrenoleukodystrophy, Zellweger syndrome), Friedreich  ataxia, Niemann-Pick diseases, neurodegeneration accompanied with brain iron accumulation, infantile neuroaxonal dystrophy, ferritinopathy, aceruloplasminemia. Intensive production of free oxygen species underlies the emergence of the diseases, therefore studying their ethiology, pathogenesis, clinical courses and the approaches in their early detection, treatment and prevention is one of the priority directions for genetics, biology, theoretical and applied medicine in order to determine important ethnic and age-related differences. This is of quite significance as many diseases known before as age-related now are affecting more and more of young population. Some diseases are traditionally more prevalent in some populations identified as races due to their common ancestry. It also includes altered prevalence and patterns in different ethnic groups. But nowadays the population of many countries is become more and more ethnically mixed. This is critical in diagnosing and managing some diseases as cardiovascular diseases, some autism forms with epilepsy, ischemic-hypoxic encephalopathy in children.  The authors highlight lately determined mechanisms of the impairment in pro-oxidative-antioxidative status as well as some modern medicines and approaches for the correction for some pathological conditions.

Published: April 2020

Acute kidney injury has been globally considered as a serious medical issue. Its incidence rate is increasing over the years despite the introduction of new therapies, the cause of which is often a side effect to drugs, or due to the impact of toxins, trauma. Nephrotoxicity is one of the most important side effects of aminoglycoside antibiotics, and on gentamicin, in particular. Despite rigorous patient monitoring, this type of nephrotoxicity appears in 10–30% of therapeutic courses. Therefore, searching for new therapies, which would be able to prevent or decrease toxic kidney injury during the treatment with aminoglycosides is quite relevant. Ademetionine is an amino acid derivative, which possesses various effects such as antioxidant, membrane stabilizing, anti-inflammatory and regenerative.

Aim of the research is to study an antioxidative activity of ademetionine in conditions of gentamicin nephropathy progression in rats. Materials and methods. Research was conducted on non-linear mature white rats weighting 130-180 g, randomly divided into 3 groups (n = 7): I group included intact control animals, II group included rodents with gentamicin nephropathy (injection of 4% Gentamicin sulphate solution in a dosage of 80 mg/kg for 6 days), III group involved the rats receiving ademetionine («Abbott SpA», Italy) in a dosage of 20 mg/kg. Peroxidation processes in blood and kidneys were evaluated by the content of active products that react with thiobarbituric acid and oxidative modification of proteins levels, antioxidant defence was assessed by catalase and glutathione peroxidase activity, SH-groups and ceruloplasmin content.

Results. In the course of experimental studies on the model of gentamicin nephropathy, the expressive antioxidant activity of ademetionine was proven: it was demonstrated by reducing the intensity of lipid peroxidation (a decrease in the content of active products that react with thiobarbituric acid) and proteins (a decrease in the content of oxidative modified proteins) in the blood and kidney homogenate, next with increased activity of the enzymatic link of antioxidant protection (glutathione peroxidase and catalase) and non-enzymatic (ceruloplasmin and compounds with SH-groups). The antioxidant potential of ademetionine has been confirmed by an increase in the antioxidant-prooxidant index in kidney tissue and a significant decrease in the index of oxidative stress in the blood of treated animals.

Conclusion. Thus, the results of experimental studies indicate the antioxidative effect of ademetionine in modelled gentamicin nephropathy, and point out the necessity of further studying its potential nephroprotectective properties.

Authors: Hien Bui Van , Truong Viet Anh , Hai Quach Thanh
Published: April 2020

Photovoltaic is used to convert electricity from solar radiation. The working characteristics of photovoltaic depend on environmental conditions such as temperature, solar radiation intensity, and the surrounding environment. During operation, the photovoltaic generation system (PGS) can be partially or completely shaded due to natural phenomena such as clouds, buildings, dust, animals, electric pillars, trees ... these are changing the characteristics of the system’s power output of PV. This paper proposes a maximum power point tracking algorithm for PGS operating under partially shaded condition (PSC) based on Particle Swarm Optimization (PSO) method, and a configuration comprises of three PV modules type PHM60W36 is used to simulate using PSIM software. The study focused on changing the working characteristics of the photovoltaic system when changing factors such as level, location of the photovoltaic module are shaded. The effectiveness of the proposed method is not only compared with the traditional Perturb and Observe (P&O) method but also compared with those proposed previously under the same operating conditions. In addition, an experimental model was developed to investigate the response of the proposed solution in the real environment with the Chroma-62050H simulator. The results show the superiority of the proposed solution in improving the performance MPPT and convergence speed of the system under complex operating conditions.
Gemological characteristics of sapphire from Hong Liem, Ham Thuan Bac district, Binh Thuan province, Viet Nam
Authors: Vu Doan Thi Anh
Published: April 2020

Basalt-related sapphire had been found in Pleistocene diluvial-diluvial deposits at Hong Liem, Ham Thuan Bac district, Binh Thuan province, Vietnam. The main color of the sapphire ranged from light to extremely dark bluish green to blue, and some are blue-yellow-green, yellow-green, and seldom yellow. Their original habits were barrel-shaped crystal and hexagonal tabula; transparency to opaque; from 2 to 10 mm in diameter, sometimes up to some cm. Some sapphire samples showed a typical trapiche sapphire. Their physical and optical properties belonged to the common sapphire range, inert under the UV lamp. Their common mineral inclusions included zircon, columbite, plagioclase, hercynite, and wüstite typical of mineral inclusions found in alkaline basalt-related sapphires.Their chemical characteristic is high Fe (0.5085–1.1364 wt%), Ti (0.0109 – 0.1042 wt%), with low contents of Cr (0.0037 – 0.0085 % wt). Their color was due to the presence of single Fe3+ at 376, 378 nm, Fe3+/Fe3+ pair at 450 nm and Fe2+/Ti4+ intervalence charge transfers (IVCT) with the maximum at 571, 579 nm, raising the absorption of Fe2+/Fe3+ IVCT towards the near-infrared (maximum approximately 870 to 890 nm). Magmatic sapphire’s source was recognized not only by the Cr2O3/Ga2O3 ratio lower than 1 but also by the structural O-H group at 3309 cm-1. This sapphire was in good quality, suitable for the jewelry of relatively high economic value.

Laparoscopic cholecystectomy is now gold standard and depends on good exposure of the peritoneal cavity. It is achieved by insufflation of the abdominal cavity with CO2. Operating at lower intraabdominal pressure (<12 -15mmHg) has been associated with fewer pulmonary and hemodynamic complications and lesser postoperative pain.

Objective: To ascertain the advantages of low pressure pneumoperitoneum over standard pressure pneumoperitoneum

Methods: Our study was quasi experimental study conducted at  KRL Hospital, Islamabad over period of 3years from 2013 to 2016. SPSS version 20 was used to calculate p value. 

Results: A total of 456 patients of gallstones were equally divided in two groups assigned to undergo low pressure (7-8mm of Hg) pneumoperitoneum or standard pressure (12-14mm of Hg) pneumoperitoneum laparoscopic cholecystectomy The average age of patients was 46.2+/-13.6yrs in group A compared to 43.5 +/- 12.9 in group B. There were 60 (26.3%) male and 168 (73.7%) female patients in group A compared to 53 (23.2% and 175 (76.85) in group B respectively. It was found that group A 14 (6.1%) had no pain, 26 (11.4%) had VAS between 1 – 7 and 188 (82.5%) had VAS of 8 – 10 where as in group B 164 (72.6%) patients reported no shoulder tip pain postoperatively, 42 (18.6%) had VAS of 1 – 7 and 20 (8.8%) had VAS OF 8 – 10. The difference was statistically significant (p-value = <0.001).

Conclusions: reduced pressure of pneumoperitoneum to 7 – 8 mm of Hg produce lower incidence of postoperative shoulder tip pain.

Published: April 2020

Objective: The post-partum intrauterine contraceptive device (PPIUCD) is a highly effective, long acting, reversible, economical and easily accessible family planning method. The aim of the study was to estimate the proportion of pregnant women aware of immediate post-partum intrauterine contraceptive device and to analyze the factors associated with acceptance.

Methodology: This is a cross sectional study in which 300 pregnant were selected who were visiting the antenatal clinics and admitted in early labor in labor ward. Their awareness and acceptance for PPIUCD was assessed through a structured questionnaire. Factors associated with acceptance were analyzed and the reasons for acceptance or refusal were determined.

Results: In this study the awareness of PPIUCD was found to be 46% and the acceptance rate of PPIUCD was 18%. The major reason for refusal was that women don’t think they need contraception immediately after delivery and secondly, they need to talk to their partners for the decision. Most common reasons for acceptance of PPIUCD was that it is long acting and reversible.

Gravidity (p= 0.006), parity (p< 0.001), unplanned pregnancy (p= 0.002) and inter pregnancy interval (p= 0.004) were the factors significantly influencing the acceptance of PPIUCD.

Conclusion: This study revealed that awareness regarding PPIUCD is increasing in women but acceptance is still poor. It was due to misconception that no contraception is needed in postpartum period. Provision of adequate knowledge regarding convenience and effectiveness of post-partum contraception in preventing unintended pregnancies can play vital role to increase its acceptance.

Published: April 2020

Inadequate endometrial proliferation is a known cause of implantation failure in assisted reproductive technology cycles. It is generally agreed that >9 mm endometrial thickness is associated with higher implantation. Several strategies have been explored to enhance endometrial proliferation. However, the results are either poor, inconsistent or subject to safety concerns. A 34-year old woman presented with unexplained thin endometrium in successive frozen embryo transfer (FET) cycles. Autologous platelet-rich plasma (PRP) was infused in the uterine cavity on day 10 of second FET cycle enhancing endometrial thickness, which post-PRP infusion measured 10.9 mm. Blastocyst-stage embryos were transferred resulting in a successful pregnancy. Autologous intrauterine infusion of PRP positively impacts endometrial proliferation and implantation which is safe, low resource and minimally invasive.
Vitamin D deficiency: It's contributing factors and prevention
Authors: Naeem Zahid
Published: April 2020

Vitamin D deficiency is prevalent across the globe. The most important role of vitamin D is in strengthening the bones. Besides this, vitamin D is likely to be associated with prevention against different types of cancers and chronic diseases like cardiovascular diseases, hypertension, diabetes mellitus and stroke as well as osteoporosis. It also has role in preventing many neurological diseases like depression, chronic fatigue syndrome and neuro-degenerative diseases including Alzheimer’s disease autoimmune diseases, birth defects and periodontal diseases.

Main source of vitamin D is sunlight, also called sunshine vitamin. People with old age, dark skinned and obese cannot produce sufficient amount of Vitamin D. Food sources include fatty fish, animal liver, egg yolk and dairy products, though these are poor sources. Vitamin D deficiency is endemic in Pakistan, India, Sri Lanka as well as Middle Eastern Countries. Though it’s sunny there all the year round, still the bulk of population is vitamin D deficient due to limited sun exposure in extremes of high temperature and socio religious reasons.  Similarly, population in Europe and America are also affected. Pregnant mothers and infants are more at risk. Population at risk should be screened and treated. Appropriate health policies, public awareness, and fortification of dairy products can definitely prevent as well as address this huge burden of disease.

Stress-Strain Constitutive Material Models for Hybrid Steel Fiber Reinforced Concrete
Authors: Jamshidi Avanaki Mohammad , Abedi Mohammad , Hoseini Abdollah
Published: April 2020

Recent advancements in fiber reinforced concrete (FRC) technology has led to the development of fibrous concrete composites, comprised of fibers with different material and/or geometry, commonly known as hybrid FRC. In one type of hybrid FRC composites, advantageous behaviors of fibers of the same material but with different geometries are gathered in a single FRC mix. The aim of this paper is to develop and validate stress-strain relationships for hybrid steel FRC composites. Six different steel FRC mixes are produced and characterization tests are conducted. Cube, cylindrical and beam specimens are produced for each characterization test corresponding to each of the Steel FRC (SFRC) composites. In this regard, an experimental program is performed to determine the basic engineering properties of SFRC composites using standard compressive, splitting tensile and three-point bending tests. The prescribed procedure of the RILEM guideline, originally developed for non-hybrid FRC, is followed using the obtained experimental results to develop stress-strain behavior models for the SFRC mixes. To validate results for the hybrid SFRC composites, numerical simulations of the 3-point bending tests were performed and compared to that of corresponding experimental results. The results indicated that the proposed stress-strain relationships yield acceptable results for characterizing the behavior of hybrid SFRC composites.
