Rapid identification of Aspergillus fumigatus within the section Fumigati
Rita Serrano, Leonor Gusm?o, António Amorim, Ricardo Araujo
BMC Microbiology , 2011, DOI: 10.1186/1471-2180-11-82
Abstract: A multiplex PCR was developed using prior information based on β-tubulin (βtub) and rodlet A (rodA) partial gene sequences. PCR amplification of βtub and rodA fragments resulted in a distinctive electrophoretic pattern in A. fumigatus and N. udagawae. The polymorphisms found in the smallest amplified sequence of βtub (153 bp) and rodA (103 bp) genes were then compared among and within species of this taxonomic section. βtub was able to differentiate among 13 individual species and two groups of species that included the pathogenic fungus A. lentulus. A more limited number of sequences were available for rodA; nevertheless, we were able to distinguish Aspergillus viridinutans, N. hiratsukae and N. udagawae.The assay described in the present study proved to be specific and highly reproducible, representing a fast and economic way of targeting molecular identification of the relevant mould, A. fumigatus, in clinical laboratories.Aspergillosis is the most common invasive mould disease worldwide. Recently, molecular techniques have been applied to fungal diagnosis and to the identification of species, and new fungal species that are morphologically similar to A. fumigatus have been described, authenticated and included in section Fumigati [1-3]. Therefore, this section now includes a few anamorphous Aspergillus species and teleomorphic species that are found in the genus Neosartorya [4]. The characteristics of the colonies on standard culture media are often similar to A. fumigatus, but conidia may be rather distinct. Neosartorya species produce heat-resistant ascospores [4].Misidentification of fungal species within the section Fumigati has been increasingly reported by clinical laboratories. Species, such as Aspergillus lentulus, Aspergillus viridinutans, Aspergillus fumigatiaffinis, Aspergillus fumisynnematus, Neosartorya pseudofischeri, Neosartorya hiratsukae and Neosartorya udagawae, are frequently reported as A. fumigatus [1,2,5,6]. Some of these species have been

Abstract: background: the prevention of violence in its general and familial framework is a priority that demands an exhaustive knowledge of its magnitude; since it is observed as a matter of public health by its negative impact in society. objective: to characterize the behavior of the intrafamilial violence against the elderly in nuevitas municipality. method: a descriptive retrospective study during the 2006 was conducted. of an universe of two thousand hundred-six, seventy-five were mistreated constituting the sample. the primary source was a survey and a family record. results: the 3,58% of the senescents received violence, of them 46,67% with ages between 60 to 69 years, the 60% in the female sex prevailed. the 86,67% corresponded to dysfunctional families. the psychosocial characteristics and the sanitary culture were bad in 64% and 34,67% respectively. the abuse that prevailed was for family negligence. conclusions: the incidence in the mistreated elderly in the municipality was very below the revised statistics.
Inferior Vena Cava Filter Placement during Pregnancy: An Adjuvant Option When Medical Therapy Fails
Sara Valadares,Fátima Serrano,Rita Torres,Augusta Borges
Case Reports in Obstetrics and Gynecology , 2013, DOI: 10.1155/2013/821635
Abstract: The authors present a case of a 27-year-old multiparous woman, with multiple thrombophilia, whose pregnancy was complicated with deep venous thrombosis requiring placement of a vena cava filter. At 15th week of gestation, following an acute deep venous thrombosis of the right inferior limb, anticoagulant therapy with low-molecular-weight heparin (LMWH) was instituted without improvement in her clinical status. Subsequently, at 18 weeks of pregnancy, LMWH was switched to warfarin. At 30th week of gestation, the maintenance of high thrombotic risk was the premise for placement of an inferior vena cava filter for prophylaxis of pulmonary embolism during childbirth and postpartum. There were no complications and a vaginal delivery was accomplished at 37 weeks of gestation. Venal placement of inferior vena cava filters is an attractive option as prophylaxis for pulmonary embolism during pregnancy. 1. Introduction Pregnancy and postpartum are periods of higher risk of thromboembolic events. Physiological changes in hemostasis and dynamics of venous return, genetics, and environmental factors contribute to this increased risk [1]. 2. Case Presentation We report the case of a 27-year-old multiparous woman, with multiple thrombophilia, whose pregnancy was complicated with deep venous thrombosis (DVT) requiring placement of a vena cava filter. She had a history of a previous DVT in the left leg at age 20, three months after beginning hormonal contraceptives. At that time a protein C deficit was diagnosed and she started anticoagulation with warfarin. At age 24, she was referred to our preconceptional clinic and a complete thrombophilia screening confirmed the protein C deficit (21%) and revealed the existence of other thrombophilia: heterozygosity for both factor V Leiden and prothrombin G20210A mutations and a positivity for lupus anticoagulant. She was overweight (body mass index of 28?kg/m2). There was no history of smoking habits or other personal and familiar thrombotic risk. During her first pregnancy warfarin was switched to prophylactic low-molecular-weight heparin (LMWH)—nadroparin calcium. Pregnancy passed uneventfully and at 39 weeks she had a normal delivery of a 3740?g healthy baby. Anticoagulation with warfarin was restarted in the puerperium. Two years later she had her second planned pregnancy and anticoagulation was switched to LMWH in therapeutic doses. At 13 weeks of gestation, by self-initiative, she reduced LMWH dosage. Two weeks later she presented to our outpatient clinic with an acute deep venous thrombosis (DVP) of the right inferior
Textile dyeing industry an environmental hazard  [PDF]

Abstract: Color is the main attraction of any fabric. No matter how excellent its constitution, if unsuitably colored it is bound to be a failure as a commercial fabric. Manufacture and use of synthetic dyes for fabric dyeing has therefore become a massive industry today. In fact the art of applying color to fabric has been known to mankind since 3500 BC. WH Perkins in 1856 discovered the use of synthetic dyes. Synthetic dyes have provided a wide range of colorfast, bright hues. However their toxic nature has become a cause of grave concern to environmentalists. Use of synthetic dyes has an adverse effect on all forms of life. Presence of sulphur, naphthol, vat dyes, nitrates, acetic acid, soaps, enzymes chromium compounds and heavy metals like copper, arsenic, lead, cad- mium, mercury, nickel, and cobalt and certain auxiliary chemicals all collectively make the textile effluent highly toxic. Other harmful chemicals present in the water may be formaldehyde based dye fixing agents, chlorinated stain removers, hydro carbon based softeners, non bio degradable dyeing chemicals. These organic materials react with many disinfectants especially chlorine and form by products (DBP’S) that are often carcinogenic and therefore undesirable. Many of these show allergic reactions. The colloidal matter present along with colors and oily scum increases the turbidity, gives the water a bad appearance and foul smell and prevents the penetration of sunlight necessary for the process of photosynthesis. This in turn interferes with the Oxygen transfer mechanism at air water interface which in turn interferes with marine life and self purification process of water. This effluent if allowed to flow in the fields’ clogs the pores of the soil resulting in loss of soil productivity. If allowed to flow in drains and rivers it effects the quality of drinking water in hand pumps making it unfit for human consumption. It is important to remove these pollutants from the waste waters before their final disposal.
Adsorption of Dye Eosin from an Aqueous Solution on two Different Samples of Activated Carbon by Static Batch Method  [PDF]

Journal of Water Resource and Protection (JWARP) , 2012, DOI: 10.4236/jwarp.2012.42011
Abstract: Removal of dye Eosin on two different samples of activated carbon by static batch method was studied. Experimental data on optical density of blank solutions of different concentrations ranging from 10 to 100 mg/L and optical density of solutions after adsorption on activated carbon samples were taken and analyzed. Calibration curves were plotted and the amount of dye adsorbed was calculated. The data was fitted to Langmuir and Freundlich isotherms for two different carbon samples and different concentration values. Constants were calculated from the slope and intercept values of the isotherms. Coefficient of correlation R2 and Standard Deviation SD were also noted. The data fitted well to the iso- therms. It was observed that adsorption decreased with increase in ppm concentrations. Carbon sample C2 showed higher potential to adsorb the dye Eosin as compared to carbon sample C1. Further Carbon sample C2 showed better adsorption in acidic pH as compared to in alkaline pH. From the analysis of the data it is shown that C2 sample has a good capacity to remove the textile dye from the residue water.

Abstract: Removal of dye Acid Yellow RR, using two different samples of activated carbon by static batch method was studied. Experimental data on optical density of blank solutions of different concentrations ranging from 10 to 100 mg/L and optical density of solutions after adsorption on activated carbon samples were taken and analyzed. Calibration curves were plotted and the amount of dye qe adsorbed was calculated. The data was fitted to Polynomial, Langmuir and Freundlich isotherms for two different carbon samples and different concentration and pH values. Constants were calculated from the slope and intercept values of the isotherms. Coefficient of correlation R2 and Standard Deviation SD were also noted. The data fitted well to the isotherms. Carbon sample C1 showed higher potential to adsorb the yellow dye. Adsorption was higher at lower concentrations of the solution. Carbon sample C2 showed better adsorption in acidic pH as com- pared to in alkaline pH. From the analysis of the data it is shown that C2 sample has a good capacity to remove the textile dye from the residue water although sample C1 was still better.
Preimplantational genetic diagnosis: an actual alternative with future implications
Claudia Juliana Serrano Serrano
MedUNAB , 2005,
Abstract: Preimplantational genetic diagnosis (PGT) isa new technique, promoted as an alternative for prenatal diagnosisand eventually for the voluntary termination of pregnancy whenthe couple is willing . Essentially, they are afraid that a geneticdisease may be transmitted to their descendents. After the assistedreproduction techniques have been applied, an embryo biopsy isconducted, extracting two of the blastomeres, which are geneticallyanalyzed. Those embryos free from genetic diseases are implantedin the mother uterus. PGT has also allowed the medical communityto study different aspects of the early embryo development andthe comprehension of reproductive genetics. However these newtechniques have given rise to many ethical questions and debatesabout the moral consequences of routinely practicing PGT.

Marcos Serrano-Due?as, Belén Calero, Maite Serrano
Advances in Parkinson's Disease (APD) , 2017, DOI: 10.4236/apd.2017.63008
Abstract:
Objective: The Tower of Hanoi measures executive functions using non-verbal content and requires perception of position in space. The main objective of this study is to standardize the use of the TOH as a measurement tool in Parkinson’s disease. Patients and Methods: Of the Control Group subjects, 192 (59.6%) were women, 223 subjects (69.25%) were able to perform the TOH with 3 discs. In the Parkinson’s Group, there were 57 women (39.3%), and 66 subjects (45.5%) did not get past that level. Results: If we take the TOH (with 3 or 4 discs) as a tool for discriminating between those who have dysexecutive syndrome and those who do not, we find that the Parkinson’s Group presents dysexecutive syndrome significantly more frequently than the Control Group (p ≤ 0.0064). Conclusion: We can conclude that dysexecutive syndrome is frequent in Parkinson’s patients and it is more prevalent than in the general population.
Theoretical Investigations of Ti-Based Binary Shape Memory Alloys  [PDF]
Rita John, Hannah Ruben
Materials Sciences and Applications (MSA) , 2011, DOI: 10.4236/msa.2011.210184
Abstract: The electronic structure and ground state properties of TiX (X = Fe, Ni, Pd, Pt and Cu) type Shape Memory alloys have been calculated using the self consistent Tight- Binding Linear Muffin Tin Orbital (TB-LMTO) method. The systematic total energy studies made on TiX alloys in both B2 and (B19/B19’) structures successfully explain the structural stability of these compounds. The equilibrium lattice parameters, bulk moduli (Bo), cohesive energy (Ecoh) and heat of formation (ΔH) are calculated for these systems and compared with the available experimental and other theoretical results. The bonding nature of these TiX alloys is analyzed via the density of states (DOS) histogram.
A Multi-Leveled Approach to Intrusion Detection and the Insider Threat  [PDF]
Rita M. Barrios
Journal of Information Security (JIS) , 2013, DOI: 10.4236/jis.2013.41007
Abstract:

When considering Intrusion Detection and the Insider Threat, most researchers tend to focus on the network architecture rather than the database which is the primary target of data theft. It is understood that the network level is adequate for many intrusions where entry into the system is being sought however it is grossly inadequate when considering the database and the authorized insider. Recent writings suggest that there have been many attempts to address the insider threat phenomena in regards to database technologies by the utilization of detection methodologies, policy management systems and behavior analysis methods however, there appears to be a lacking in the development of adequate solutions that will achieve the level of detection that is required. While it is true that Authorization is the cornerstone to the security of the database implementation, authorization alone is not enough to prevent the authorized entity from initiating malicious activities in regards to the data stored within the database. Behavior of the authorized entity must also be considered along with current data access control policies. Each of the previously mentioned approaches to intrusion detection at the database level has been considered individually, however, there has been limited research in producing a multileveled approach to achieve a robust solution. The research presented outlines the development of a detection framework by introducing a process that is to be implemented in conjunction with information requests. By utilizing this approach, an effective and robust methodology has been achieved that can be used to determine the probability of an intrusion by the authorized entity, which ultimately address the insider threat phenomena at its most basic level.
