Published: February 2020

Mechanical alloying (MA) is an efficient approach for fabricating ODS alloys and structural materials including vanadium alloys for fusion and fission applications. Dissolution behavior of the alloying elements is a key issue for optimizing the mechanical alloying process in fabricating vanadium alloys. This paper studies the MA process of V-4wt.%Cr-4wt.%Ti alloy. The outcomes of the MA powders in a planetary ball mill are reported in terms of powder particle size, morphology and composition evolution. The impact of spark-plasma sintering process on the mechanically alloyed powder is analyzed. The microstructure of the V-4wt.%Cr-4wt.%Ti alloy prepared by mechanical milling is investigated with a X-ray diffractometer and scanning electron microscope.

The use of dental radiographies is nowadays indispensible for the clinician, and the evolution of x-rays provide quality images of the anatomic structures. The indications for a radiographic exam must be based on a clinical examination of the patient. Although the most used radiographies in dentistry are the retroalveolar and the panoramic one, it is considered that the indication for a CBCT scanning should be professional justified and evaluated as a balance between the benefits and the risk of exposure at radiation. The CBCT scans provide good quality images of the anatomic structures, with an accurate delimitation of the pathologic lesions, fact that allows the practitioner to proper evaluate the surrounding structures. CBCT technique uses an x-ray beam shaped like a cone that records 3D images in a single gantry rotation (360 degrees) within 6-20 seconds, with a radiation dose that depends on several factors. The comparison of the radiation dose of the CBCT (11-674 mSv) and the panoramic radiography (2.7�24.3 mSv) demonstrates that the CBCT requires a higher dose of radiation, but the high image quality is competing with the ones obtained with MSCT (280�1,410 mSv). The panoramic radiography uses an x-ray beam that is angled at aproximately 8 degrees, providing the practitioner a 2D radiographic image of the anatomic structures. The disadvantages of the panoramic radiography are the overlapping of the anatomic structures, the distortion and the blurry image. The study is based on the measurements of cystic lesions of the mandibular and maxillary bone that were present on radiographies and CBCT scans of 25 patients. The result of the measurements was that significative differences were found between the panoramic image of the cyst and the reconstructive image that the CBCT.

The past decades demonstrated that saliva and its components represent a remarkable diagnosis fluid with valuable clinical uses for both oral and systemic diseases. At the same time it is well established that oxidative stress is involved in a wide number of pathologies, including periodontitis. The specific aim of the present study which included 50 subjects is to determine if saliva can be used in clinical settings to correlate oxidative stress and tissue destruction markers with the severity of periodontal disease. An important oxidative stress marker - 8-hydroxydesoxyguanosine (8-OHdG) and a collagen degradation marker - beta-crosslaps (b-CTX) were quantified in both saliva and gingival crevicular fluid (GCF) using ELISA kits and were found to be significantly increased in the chronic periodontitis group when compared to respective controls (p[0.05). At the same time positive correlations were observed between whole saliva and gingival crevicular fluid (p[0.05). Significant correlations were also determined between GCF and salivary markers and clinical parameters of periodontal disease. Present results demonstrate that saliva and its components can successfully be used in clinical settings and represents a reliable tool for assessing periodontal disease severity.

Reactive oxygen species (ROS) and reactive nitrogen species (RNS) play a physiological role as secondary messengers in a variety of cellular metabolic pathways. However, in certain pathological states the disequilibrium between oxidants and antioxidant systems can alter normal cell function and even induce deleterious phenotypical changes which further aggravate the underlying pathology. This has been especially evident in the case of vascular smooth muscle cells (VSMC) which are exposed to increased amounts of ROS, in various disease processes (i.e. atherosclerosis, diabetes). The purpose of this review is to examine the current knowledge regarding the effect of oxidative stress on vascular structure in general, and in chronic kidney disease, in particular.

Ricin, a toxic glycoprotein found in the seeds of castor oil plant, is capable of irreversible cellular adhesion and inhibition of protein synthesis. The authors performed an up to date review concerning the chemical structure, mechanism of action, poisoning symptoms and treatment, and potential uses of ricin as a biochemical weapon. Castor oil plant is easy to cultivate and harvest worldwide and, except the United States of America, cultures and processing plants are not supervised. Ricin extraction does not require laborious and costly technique and it is undetectable once in the body (except for urine in case of ricin ingestion). Poisoning generates nonspecific symptoms and is potentially fatal with no antidote or specific treatment available. Forensic specialists must be aware of symptoms and post-mortem findings in order to make a correct diagnosis of ricin poisoning.

Endometriosis is described as a gynecological disorder characterized by the presence of endometrial tissue outside the uterus; extensively explored because of its increasing incidency, with an indubitable diagnostic only after invasive surgery, with no efficient treatment, it has still many aspects to be elucidated. A growing body of facts sustain oxidative stress as a crucial factor between the numerous incriminated factors implicated in endometriosis ethiopathogeny. Reactive oxygen species(ROS) act to decline reproductive function. Our study intends to determine if an experimental model of endometriosis may be useful to assess the impact of oxidative stress on endometrial cells; we have used a murine model of 18 adult Wistar female rats. A fragment from their left uterine horn was implanted in the abdominal wall. After 4 weeks, a laparatomy was performed, 5 endometrial implants were removed, followed by biochemical tissue assay of superoxide dismutase(SOD) and catalase(CAT). At the end of the experiment, the rats were sacrificed, the implants were removed for histopathological exam and biochemical assay of antioxidant enzymes. The results revealed decreased levels of antioxidant enzymes, pointing on significant oxidative stress involvement.

Published: February 2020

From our research we noticed that Acanthi balcanici herba (ABH) contains luteolin and quercetol and Myrtillus fructus (M-fr) contains chlorogenic acid, apigenol and rutoside. ABH has no antibacterial effect on any species tested, completely cancel the therapeutic effect of three drugs (amoxicillin + clavulanic acid, levofloxacin, amikacin) and have no significant effect on the other two antibiotics (cefotaxime and ceftazidime) when they are associated. All bacterial species were sensitive to M-fr and the extract has synergistic effect in combination with levoflaxacin, amikacin and cefotaxime.

Published: February 2020

Aleurone cells of barley accumulate the major storage globular protein, which is deposited in different patterns, such as protein and lipid self-assemblies. To better understand the complexity of storage self-assemblies, a fatty acid is chosen as a lipid model, namely stearic acid, SA, because of its high stability in monolayers at the air/aqueous solutions interface. The effect of aleurone cell protein, AC protein, on the phase behavior and surface structure of SA monolayers at the air/water interface has been studied by a combined Langmuir and Langmuir-Blodgett (LB) technique and by atomic force microscopy (AFM) investigation. The AC protein and SA monolayers were transferred on glass support, at several controlled surface pressures, characteristic for both the condensed liquid and solid phase of pure SA monolayers. The results indicate that globular particles of AC protein adsorb on and penetrate into and specifically interact with SA monolayers stabilizing the lipid/protein interface by achieving highly ordered self-assemblies, which may also occur within aleurone layers. These structures might play an important role both in aleurone cell development and in seedling growth.

Published: February 2020

Obesity involves the growth of adipose tissue cells (adipocytes and preadipocytes), as well as microvascular endothelial cells. Matrix metalloproteinases (MMPs) are relevant ezymes for the modulation of extracellular matrix (ECM) and adipocyte and preadipocytes differentiation. They are elevated in obese patients, generating abnormal ECM metabolism.[1]. This article proposes a thorough study of literature with focus on the important roles of matrix metalloproteinases in the pathophysiology of obesity. The article represents a narrative review based on an English-language PubMed research of the medical literature regardind important aspects of the proposed aim. MMP-2 activity was signi�cantly higher than MMP-9, both activities were detectable. MMP-9 was strongly correlated with body weight parameters before surgery, as well as after significant body weight reduction as a result of bariatric surgery. Concerning MMP-2 and MMP-9 they are also involved in the turnover of basement membranes both those of adipose tissue and endothelial. MMP-9 levels were moderately correlated with HDL cholesterol levels. Taken together, the present data suggest that changes in ECM through MMP-mediated degradation might play a critical role in the adipocyte differentiation process. These findings are detected both in clinical trials and in laboratory animal experiments. It is then tempting to speculate that the adipocyte-derived MMPs might represent a new pharmacological target for the inhibition of adipose tissue growth by inhibiting adipose differentiation as well as angiogenic process.

Published: February 2020

The dose dependent effect of gamma irradiation on collagen in vegetable tanned leather was studied by the MHT method. Examination of the irradiated samples at 3 months after the irradiation treatment revealed variations of the main shrinkage temperatures and intervals. Up to 25 kGy, the shrinkage temperature does not vary while the total shrinkage interval decreases suggesting cross-linking as the main process. At higher doses, the decrease of shrinkage temperature is accompanied by the increase of the total shrinkage interval indicating that peptide chain scission becomes predominat. Quebracho-tanned sheep leather shows to be the less resistant to the deterioration effect of gamma radiations, while both mimosa-tanned goat leather and quebracho-tanned calf leather better withstand the destabilization effects.

The aim of the study was to investigate the effect of xylitol, from some oral hygiene products and chewing gums, on salivary parameters variation in patients with carious disease. The study was performed on 30 patients with a medium level of carious disease, randomly divided in two groups as follows: group 1 (study group), using xylitol-based products for 30 days, and group 2 (control group), using products without xylitol. The way of administration, dose, and frequency of use were as follows: toothpaste (normal daily brushing, 3 times daily); mouthwashing (5 ml, twice daily); chewing gums (two tablets, 5 times daily), for 30 days. The assessment targeted the salivary parameters as follow: saliva microcrystallisation index (IMK), resting salivary flow rate (RSF), stimulated salivary flow rate(SSF). The results of our study confirm the improvement of salivary parameters due to the use of xylitol-based products, by the positive influence on the remineralisation capacity of saliva. The assessment method of saliva IMK represents a noninvasive, simple, informational indicator for the assessment of the remineralisation capacity of saliva.

Published: February 2020

Metabolic surgery is the most efficacious method for the treatment of morbid obesity and was recently included among the antidiabetes treatments recommended in obese type 2 diabetes (T2D) patients. The aim of this study was to compare in a randomized controlled trial the effect of sleeve gastrectomy (SG) to that of intensive lifestyle intervention plus pharmacologic treatment on some markers of insulin resistance and beta cell function as well as some appetite controlling hormones in a group of male obese T2D subjects. The study groups comprised 20 subjects for SG and 21 control subjects. Fasting blood glucose, insulin, proinsulin, adiponectin, leptin, ghrelin, HOMA-IR, HOMA-%B, proinsulin-to-insulin ratio and proinsulin-to-adiponectin ratio were evaluated at baseline and after one year follow-up. Overall, patients in the SG group lost 78.98% of excess weight loss (%EWL) in comparison with 9.45% in the control group. This was accompanied by a significant improvement of insulin resistance markers, including increase of adiponectin and decrease of HOMA-IR, while no changes were recorded in the control group. Weight loss was also associated with a significant improvement of proinsulin-to-insulin and proinsulin-to-adiponectin ratio, both surrogate markers of beta cell dysfunction. These also improved in the control group, but were only marginally significant. Our findings suggest that improved insulin resistance and decreased beta cell dysfunction after sleeve gastrectomy might explain diabetes remission associated with metabolic surgery.

Published: February 2020

The ovarian hyperstimulation syndrome (OHSS) is one of the major complications which occurs as a result of controlled ovarian stimulation (COS) in the assisted human reproduction. There are several factors including age, body mass index (BMI), plasma estradiol level, the anti-mullerian hormone (AMH) level and the antral follicle count (AFC), which can be used to identify the cases with high risk for this complication. The purpose of the study is to establish the predictive value of AMH for the development of OHSS before COS as well as its association with the plasma estradiol level during stimulation. The study group included 155 COS cycles using gonadotropin-releasing hormone (GnRH) agonist protocols, and analyzed the predictive value of the mentioned parameters for OHSS. The serum AMH level is superior to age and BMI for identification of patients with high risk for OHSS before starting the ovulation stimulation, and the cut-off level is 3.78ng/mlLwith 91.1% sensibility and 85.2% specificity.

Published: February 2020

During the past few decades, the anthropogenic activities induced worldwide changes in the ecological systems, including the aquatic systems. This work analysed the contamination level of groundwater resources from a rural agglomeration (Central-Western part of Prahova County) by biological and physico-chemical approaches. The study was performed during the autumn of 2016 on several sampling sites (four drilling wells, depth higher than 100 m supplying three villages; two wells lower than 10 m depth and one spring). The water quality was evaluated by comparison with the limit values of the drinking water quality legislation (Law no.458/2002) and the Order 621/2014 (applicable to all groundwater bodies of Romania). The results showed that phenols and metals (iron and manganese) exceeded the threshold values in all sampling sites. Moreover, the anthropogenic factors including agriculture, use of fertilizers, manures, animal husbandry led to an increase of the bacterial load, particularly at wells sites.

Polyphenols are important constituents of plants, being demonstrated that long term consumption of them have potential health benefits as antioxidant. In the experimental part of the study we separated ten polyphenolic compounds by thin layer chromatography (TLC) from hydroalcoholic hypoglycemic plant extracts (Ericaceae family). In the theoretical study part we consider important to characterize the structural properties of the substances using molecular mechanics studies. The selected physico-chemical descriptors were: HOMO and LUMO orbitals frontier, water solubility, partition coefficient, dipole moment, heat of formation, stabilization energy of the molecule and number of proton donor groups. We realized a comparative QSPR regression correlation study of molecular surface area and Rf with the selected desriptors. From studies we observed the relationship between the two parameters Rf and MSA, which correlates very well with common descriptors.

Microwave heating is a common cooking procedure.Heating can accelerate oxidative processes in oil sand oxidation products are known to have potential toxic effects on human health.Therefore it would be useful to have a method to anticipate the vegetable oils behaviour under thermal conditions. Several methods to evaluate total oxidant activity were developed but unfortunatelly their ability to predict the oxidative changes during heating are poorly estimated. In this study we evaluated the relation of TEAC FRAP and CUPRAC values together with total polyphenols and flavonoids content of several commercial available vegetable oils with conjugated dienes and TBAR�s products during 15 min microwave heating. FRAP values were correlated with oxidative parameters after 15 min heating.

The aim of the research is to investigate the characteristics of cranial base morphology in class II division 1 and class II division 2 malocclusions. The study group consisted of 40 patients aged 11 years treated at the Orthodontic Department of �Carol Davila� University. Both gender and both malocclusion types were equally represented. Lateral cephalograms were traced and 22 linear and angular cephalometric parameters were calculated: four parameters for the cranial base (N-S-Ba, N-Op-Ba angles, N-S, S-Ba lengths) and 18 parameters for the maxillofacial complex Nsa-Nsp, Go-Gn, Kdl-Go, S-Nsp, N-Nsa, Nsa-Gn, N-Gn, Nsp-Go, SNA angle, ANB angle, SN � NsaNsp angle, SN-GoGn angle, N-Nsa-Gn angle, S-Nsp-Go angle, N-Nsa-Pg angle, gonial angle, FMA angle, NsaNsp � GoGn. Statistical significant differences between cranial base parameters in the two malocclusions groups were depicted, in particular for feminine gender. Regardless of gender, the sphenoidal angle values were mainly increased in both malocclusion groups, when compared to normal population values. The S-Ba lengths were decreased in both malocclusion groups, regardless of gender. More significant alterations of cranial base morphology were depicted in patients with Class II Division 2 malocclusions then in patients with Class II Division 1 malocclusion. The study�s results sustain the existence of some cranial base alterations in Class II malocclusions.

Published: February 2020

The present paper describes a simple and efficient electrophoretic method to identify the species provenience of edible eggs in food products. The proteic pattern of egg yolk and egg white was described using polyacryl amide gel electrophoresis under denaturating conditions (PAGE-SDS) separately for the egg yolk and for the egg white proteins from five edible egg species, as follows: hen, goose, duck, turkey and quail. The molecular weight of each protein strip was calculated using a molecular weight standard curve. Separately, an electrophoretic protein pattern of all the mentioned samples was done using polyacryl amide gel electrophoresis under undenaturating conditions (native PAGE). The results show clearly distinct patterns in electrophoregrams resulted both in denaturating and undenaturating conditions for each species. These methods could be useful tools for egg species routine identification in various food industrial mixtures.

Published: February 2020

Despite remarkable advancements in medicine, cancers remain one of the most challenging pathologies for doctors. Head and neck neoplasms especially raise serious management problems due to the often advanced stage at the moment of diagnosis, associated with difficult curative interventions that impose significant changes in the quality of life of patients. Whenever possible, a complete removal of the tumor with disease free margins significantly increases the rate of survival. During surgery, assessing the limit of resection up to healthy tissue is crucial in order to attempt a curative intervention. The purpose of this paper is to evaluate the use of the methylene blue staining test in assessing the margins of resection during interventions for head and neck cancers.

A tal fin, confrontaremos el registro iconográfico con la evidencia arqueológica de los sitios “Alamito” y “La Rinconada” a fin de establecer los rasgos diagnósticos que permitan identificar en esta iconografía los motivos de la cabeza “trofeo” o “suelta” y su potencial vinculación con el culto a la cabeza del antepasado.

En este trabajo realizamos una comparación de los entornos materiales construidos en dos asentamientos del primer milenio d.C. ubicados en el piedemonte meridional y oriental de las Cumbres Calchaquíes. Estos casos son el de La Bolsa 1, en el sector norte del valle de Tafí, y Mortero Quebrado, en la cuenca alta del río Anfama. Nos interesa particularmente caracterizar las similitudes y diferencias en diversos aspectos y escalas de las estructuras objetivas y prácticas de agentes que se materializan a través de la articulación del paisaje, la dinámica de escenarios domésticos y las prácticas alimentarias.

Endophytic fungi have been known to play a role in protecting their host plants against diseases and extreme environments. The purpose of this study was to determine the antagonistic activity of three Aspergillus isolates against F. oxysporum f. sp. cubense (Foc), and to identify the Aspergillus identity using multilocus phylogeny analysis. Antagonistic assay by dual culture method showed that the Aspergillus sp. strain PD2, strain PD4, and strain PD5 inhibited the growth of Foc isolate by 37.31%, 26.52%, and 12.04%, respectively. Multilocus phylogeny based on ITS rDNA, beta-tubulin, and calmodulin genes sequences showed that the Aspergillus strain PD2 and strain PD4 belong to A. section Terrei, while the Aspergillus sp. strain PD5 was identified as A. sydowii of the A. sect. Versicolores.
Optimization of growth of oyster mushroom mycelium (Pleurotus sp.) from Tasikmalaya on several kinds of cereal medium
Authors: Khusnul Khusnul
Published: February 2020

Pleurotus sp. or oyster mushroom is one type of edible mushroom that contains essential nutrients for the human body. This mushroom has been widely cultivated in Indonesia, one of which is Pleurotus sp. from Tasikmalaya. The key to the success of oyster mushroom cultivation is the seeds and growing medium or baglog, while the factors that influence the quality of the seeds include the type of medium. This study aims to determine 1) the effect of the type of seed medium from the type of cereals used on the growth of mycelium Pleurotus sp. from Tasikmalaya, 2) determine the type of seed medium that has the best mycelium growth. This study uses an experimental method with a Completely Randomized Design (CRD). The parameters measured include the main parameters, namely the rate of growth of mycelium Pleurotus sp. from Tasikmalaya on the seed medium. Supporting parameters are the quality of mycelium growth in the seed medium, the proximate value of cereals used for the seed medium. The results of the analysis showed that the medium of cereals used as seeds ready for cultivation could affect the quality of the seeds produced. The seedling medium from milled corn has the best growth of mycelium.

Red-yeasts are pigmented yeast species that could synthesize carotenoids for food supplements and pharmaceutical purposes. However, this group contains a lot of species which need to be explored thoroughly. The objective of this study was to view the β-carotene production of three indigenous red-yeasts by modifying glucose content in the growth medium and verifying their phylogenetic relationship. The glucose content modification in growth media influenced the β-carotene production of each species. Rhodosporidiobolus ruineniae (InaCCY1638/Y15Eg075) and Rhodosporidiobolus poonsokiae (InaCCY1606/Y15Kr068) produced higher β-carotene than Rhodotorula paludigena (InaCCY1527/Y15Eg004). These Rhodosporidiobolus species were able to produce higher β-carotene from 0.5 to 2% glucose content while Rhodotorula was low production in 2% glucose content. The higher producers by Rhodosporidiobolus species were clustered to Ruineniae clade and could be a potential clade for higher β-carotene production. Based on this result, using a high carotenoid producer of red-yeasts from indigenous strains is potential to be developed for β-carotene bioindustry in the future.

The target group being used were students of XI-MIA class. Results of research indicated that CBT was effectively improved students’ self-efficacy on mathematics. Students’ self-efficacy of post intervention was higher than pre intervention of CBT for each single subject of study. The authors recommended for the counseling teachers to use CBT as one of the techniques to improve students’ self-efficacy on mathematics. The teacher of mathematics were also expected not only delivered mathematical contents, but also are expected to strengthen students’ beliefs and self-efficacy on mathematics. For the following researchers, we would like to suggest to enlarge subjects not only for senior secondary classroom, but also for junior high school and primary school classroom. Suggestion also were addressed for subjects other than mathematics that students have lower self-efficacy, and with group setting.
