Ovariectomy at 3 or 10 weeks of age does not affect the ventilatory response to hypoxia in adult rats  [PDF]
Aida Bairam
Open Journal of Molecular and Integrative Physiology (OJMIP) , 2012, DOI: 10.4236/ojmip.2012.23013
Abstract: Although an ovariectomy is the routine approach used to study the role of ovarian hormones on respiratory control, the results have often been contradictory. We tested the hypothesis that the ventilatory response to hypoxia is modified by the age at which the ovariectomy is performed. Female rats were ovariectomized either atan early (3 weeks old, i.e., prepubertal) or late (10 weeks old, i.e., adult) stage, and ventilation was then assessed at 12 weeks of age using whole-body plethysmography. The control group included sham-operated rats that had undergone the same surgical procedure but were not ovariectomized. Independent of the age at which surgery was performed, ovariectomy significantly decreased circulating progesterone and 17-b-estradiol levels without re-ducing them below their detection threshold. Despite that decrease, there was no difference in baseline minute ventilation or in the ventilatory response to hypoxia (FiO2 = 12%, 20 min; expressed as the percentage of increase from baseline) between ovariectomized and shamoperated rats. These results suggest that ovariectomy at either a young or at an adult age is insufficient to completely suppress circulating hormones and disrupt the regulation of ventilation.
3D Conceptual Modelling and Direct Utilization Calculations of The Albanian Geothermal Resources  [PDF]
Nevton Kodhelaj, Aida Bode
Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.51B037
Abstract: Balneological use of the Albanian Geothermal springs and waters dates back centuries, but the first modern use started in 1937. Unfortunately they had not been used for its energetic values yet. The temperature of the water is above 60 °C and the flow above 16 l/s, thus direct utilization is possible, in particular for space heating. Three-dimensional temperature field calculations and engineering calculations on a heating system with heat exchangers are presented here. The results show that the water temperature is expected to be stable and considerably higher temperature is expected through deep well drilling. The University’s Campus of Tirana is composed of 29 buildings, which are partially heated through a coal heater. The installed capacity is 2558kW while the coal consumption is about 920 kg/h. The University’s Campus of Tirana is one of the most important areas and with the highest density of population in Tirana, so it is the best area to show the heat exchanger efficiency. The economic analyses prove that the borehole heat exchangers are more convenient than the coal heating systems.
Low Dose Total Body Irradiation for Relapsed Low Grade Non-Hodgkin’s Lymphoma: Experience of National Cancer Institute, Cairo  [PDF]
Yasser Bayoumi, Aida Radwan
Journal of Cancer Therapy (JCT) , 2015, DOI: 10.4236/jct.2015.61004
Abstract:

Background and Purpose: The relapsed low grade non-Hodgkin’s lymphoma (LG-NHL) is currently incurable disease and the optimal treatment regimen has not determined yet. Low dose total body irradiation (LTBI) provides an alternative mechanism of action against cancer cells rather than direct cell kill. The mode of action of LTBI is immune-modulatory effect, induction of apoptosis and hypersensitivity to low radiation doses. The aim of our study is to evaluate the effect of LTBI on relapsed LG-NHL and reporting our experience at National Cancer Institute, Cairo (NCI, Cairo). Material and Methods: Fifty eight patients with relapsed LG-NHL and received LTBI studied retrospectively. LTBI dose was 1.6 Gy/8 fractions divided on 2 courses; each course 4 fractions treated over 4 days with 2 weeks rest between the 2 courses. Results: The median age is 54 years; 65% of the patients are men. Forty (69%) patients had performance status of 2 or more. Twenty seven patients were stage II/III and 31 patients (53%) had stage IV disease. Twenty six (45%) patients had bulky disease more than 10 cm and 22 (38%) patients had B symptoms at the time of relapse. The extranodal disease was present in 17 patients (29%) and 78% of the patients received >3 regimens of chemotherapy before referral to LTBI. Twenty three patients received IFRT (mean dose 32 ± 4 Gy) to initially bulky sites after LTBI. Fourteen patients (24%) achieved complete remission (CR) while 45%, 21% and 10% had partial remission (PR), stable disease (SD) and progressive disease (PD) respectively. The median PFS duration was 14 months and the median OS duration was 39 months. Stage VI, >3 regimen of chemotherapy and bad response to LTBI (SD) affected progression duration adversely (0.03, 0.05 and 0.01 respectively). The response to LTBI is the only factor affected the OS duration significantly. The 3-year PFS was 19% ± 9%, and 3-year OS was 45% ± 8%. Stage IV was the only factor affected the 3-year PFS significantly with p value 0.03. The hematological toxicity was the main side effect of LTBI. Eleven patients developed G3/4 anemia while 8 patients only developed G3/4 thrombocytopenia and 13 patients developed G3/4 leucopenia. Conclusion: The use of LTBI in patients with relapsed low

Selecting representative ages for developmental changes of respiratory irregularities and hypoxic ventilatory response in rats  [PDF]

Open Journal of Molecular and Integrative Physiology (OJMIP) , 2011, DOI: 10.4236/ojmip.2011.11001
Abstract: Apnea frequency and the weak ventilatory response to hypoxia are a major clinical correlates of the immaturity of respiratory control system in preterm neonates. Rats are frequently used as model to study the respiratory control during development. However, little is known about the postnatal ages that best represent these respiratory irregularities and the hypoxic ventilatory response. Using plethysmography, we assessed baseline minute ventilation, ventilatory response to moderate hypoxia (FiO2 = 12%, 20 min) and apnea frequency in awake and non-anesthetized rats at the postnatal ages of 1, 4, 7, 12, 21 and 90 days old (P1, P4, P7, P12, P21, and P90, respectively). Baseline minute ventilation slightly increased in P4 (~25% vs P1) then gradually decreased with age (age effect: p < 0.05). The lowest level of ventilation was observed in P90 (p < 0.01 vs all ages). Minute ventilation (% from baseline) in response to hypoxia showed the well-known biphasic pattern in all rats at 12 days old or less. Minute ventilation at the initial phase of the hypoxic response was not significantly different between P1, P4, between P7, P12 and between P21, P90. The late phase of the hypoxic response was similar between P1, P4, and between P21, P90, but was significantly different between P7 and P12 (p < 0.05). Under baseline or hypoxic condition, the higher number of apnea frequency (spontaneous and post- sigh) was observed in P1, it then decreased progressively with age (age effect: p < 0.01 for baseline; p < 0.001 for hypoxia). These results suggest that when P4, P7 and P12 are selected to represent the age-dependent changes of the hypoxic ventilatory response in rats, the P1 rats should be included to better describe the age-dependence of apnea frequency.

Open Journal of Obstetrics and Gynecology (OJOG) , 2016, DOI: 10.4236/ojog.2016.68063
Abstract: Objective: Aims of the study are to study the impact of increased knowledge and awareness among staff nurses towards assessment of methods of fetal wellbeing to early identification of pregnancy outcomes and the frequency of interventions during delivery. Design: A quasi-experimental design was used in carrying out the study to impact knowledge and awareness assessment of methods of fetal wellbeing among staff nurses. The study was conducted at obstetric & gynecological department working at setting in Jarsh Governorate Hospitals & Prince Hussein Bin Abdullah Hospitals. Methods: The study sample consisted of all staff nurses working at obstetric & gynecological department in Jarsh Governorate Hospital & Prince Hussein Bin Abdullah Hospitals who have agreed to participate in the study. The current study has included 150 staff types of sample convenient sample. Results: The main findings of this study showed that there is a highly statistical significance differences between pre-test and post-test in all answers regarding knowledge about methods of fetal wellbeing assessment. Conclusion: Nurses have a major role to prevent the complication for the fetus and mother during pregnancy. Nurses coming in contact with the antenatal mothers should take initiative to provide necessary information to the women and the relatives on different methods used for the assessment of fetal wellbeing, so as to improve the quality of life among the pregnant women. For that they should adequate knowledge about all the aspects of fetal wellbeing, so that they can prevent the complication.

Open Journal of Social Sciences (JSS) , 2017, DOI: 10.4236/jss.2017.58007
Abstract: Objective: To apply the Political Economy of Aging approach to the study of the economic (in)security of the elderly in Latin America and the Caribbean. This approach studies the role of the State in the reproduction, attenuation or accentuation of inequities that affect the elderly population. Methods: Political economy indicators were applied such as a type of welfare regime, articulation of social policy based on assistance and social security, coverage, contributory and non-contributory pension systems to a sample of twenty countries of the region (Argentina, Bolivia, Brazil, Chile, Colombia, Costa Rica, Cuba, Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru, Uruguay and Venezuela). Results: The region presents a great heterogeneity in the type of State and welfare regime and its consequent effect on the economic security of the elderly. However, lack of protection exercised by the contributory systems predominates, which causes the need for non-contributory systems.
Voz de Angola em tempo de ultimato
Freudenthal, Aida;
Estudos Afro-Asiáticos , 2001, DOI: 10.1590/S0101-546X2001000100006
Abstract: considering that the ultimatum was the most abrasive diplomatic incident in the history of portuguese-british relations, denouncing the reformulation by both parties of the expansionist strategy in the south of the african continent, the author became interested in investigating the reaction of this incident in angola as well as its real impact on the various social strata, both african and european. the analysis of talks given by authorities, colonists and "native children" on the true essence of colonial domination and also on the limits of portuguese colonization led to detecting not only basic divergences but also converging opinions regarding the future of the territory. even if the ultimatum did not in fact turn out to be decisive although a political fact, the year 1890 was to be a symbol in the emergence of the proto-nationalist formulations in angola.

Effects of Bimodal Subtitling of English Movies on Content Comprehension and Vocabulary Recognition
Aida Etemadi
International Journal of English Linguistics , 2012, DOI: 10.5539/ijel.v2n1p239
Abstract: This thesis is an attempt to study the impact of bimodal subtitling on content comprehension of English movies and vocabulary recognition. Forty four senior undergraduate students studying at Shiraz Islamic Azad University were selected from two intact classes of Tapes and Films Translation course. Two BBC documentary movies (Dangerous knowledge and Where’s my robot?), one with English subtitles and the other without subtitles were selected based on the content and level of difficulty of the language. First, both classes watched the same movies, but class 1 first watched ‘Dangerous knowledge’ with English subtitling and then ‘Where’s my robot?’ without subtitling. To counteract the order effect class 2 first watched ‘where’s my robot?’ and then ‘Dangerous knowledge’. After viewing the movies, the participants answered the relevant multiple choice vocabulary and content comprehension questions. The data gathered were subjected to the statistical procedure of paired samples t-test. The results clearly indicated that bimodal subtitling had a positive impact on content comprehension of English movies. It can be said that the participants comprehend the subtitled movie better than the one without subtitle. However, for some reasons bimodal subtitling did not have an effect on participants’ vocabulary recognition.
