OCLC Number/Unique Identifier: 7317595274
Aims and objectives: By reporting the use of therapeutic nursing interventions to facilitate the process of change in a depressive elderly caregiver, this paper seeks to underline the importance of fitting interventions to individual clients.
Background: In assisting families of chronic illness sufferers, it must be remembered that the perceptions and functions of both clients and families are determined by family members, and that changes, if any, are made by those clients and families, rather than by nurses. However, nurses do play an important role in facilitating the process of change.
Design: This is a case report.
Methods: A case study of a depressive elderly caregiver is used to examine the use of therapeutic nursing interventions to facilitate the process of change with problem analysis, case conceptualisation and specific skills employed documented.
Results: The change from one therapeutic approach (Cognitive-behavioural therapy) to another (Narrative Therapy) facilitates enlisting the caregiver’s unique strengths, resources and competence to overcome the difficulties and challenges identified during the process of change. In dealing with depression in family caregivers, nurses should not only be flexible but also remain sceptical in using different approaches, with heightened awareness of the client’s circumstances.
Unsteady and Incompressible Magneto-Hydrodynamics Blood Flow in an Inclined Cylindrical Channel
Published on: 18th August, 2023
In the current study, the blood flow through an inclined cylindrical tube subjected to an external magnetic field is evaluated. The blood flow has been considered under the consequence of a transverse magnetic field. Previously the mathematical model was solved by using Caputo-Fabrizio (CF) fractional order derivative with a non-singular kernel which has the limitations like it fails to satisfy the fundamental theorem of fractional calculus. Whereas, in the present study Adomian Decomposition Method (ADM) which is suitable for all types of linear and non-linear differential equations is used. The flow of magnetized blood in an inclined cylindrical tube has been studied by using the ADM. An external magnetic field and an oscillating pressure gradient drove the blood flow. ADM algorithm has been developed and used to find the Adomian solution. Computer software MATHEMATICA has been used to visualize the influence of various flow characteristics such as Hartmann number (Ha), different radial locations and angle of inclination on the Adomian velocity. Due to the Lorentz effect and central radial location, the results show that the magnetic field diminishes the velocities of blood. Meanwhile, progressive inclination angle enhanced the blood flow.
Rosai-Dorfman disease presenting as a breast mass

Rosai-Dorfman disease (RDD) is an idiopathic, benign proliferation of histiocytes that can be present in multiple organs such as lymph node, skin, soft tissue, orbit, central nerve system and bone; however, it rarely occurs in the breast. In general, RDD is a painless, firm and poorly defined lesion, which can radiologically mimic a breast cancer and is therefore an important differential consideration. The diagnosis of breast RDD is challenging, especially on a small biopsy specimen. We report a unique case of breast RDD with a literature review including common presentation, differential diagnosis, and recommended management. A high index of suspicion for this rare entity is essential to render a correct diagnosis, thereby avoiding unnecessary diagnostic tests and treatment.
Auxin-like and Cytokinin-like Effects of New Synthetic Pyrimidine Derivatives on the Growth and Photosynthesis of Wheat
Published on: 19th March, 2024
The regulatory effect of new synthetic thienopyrimidine derivatives on the growth and photosynthesis of wheat (Triticum aestivum L.) variety Svitlana in the vegetative phase was studied. The regulatory effect of new synthetic thienopyrimidine derivatives was compared with the regulatory effect of auxin IAA (1H-indol-3-yl)acetic acid) or synthetic plant growth regulators Methyur (sodium salt of 6-methyl-2-mercapto-4-hydroxypyrimidine) and Kamethur (potassium salt of 6-methyl-2-mercapto-4-hydroxypyrimidine). After 2 weeks, morphometric parameters (such as average length of shoots and roots (mm), average biomass of 10 plants (g)) and biochemical parameters (such as content of photosynthetic pigments (µg/ml)) of wheat plants grown from seeds treated with synthetic thienopyrimidine derivatives, or auxin IAA, or synthetic plant growth regulators Methyur and Kamethur at a concentration of 10-6M, were measured and compared with similar parameters of control wheat plants grown from seeds treated with distilled water. The regulatory effect of new synthetic thienopyrimidine derivatives on the morphometric and biochemical parameters of wheat plants was similar or higher compared to the regulatory effect of auxin IAA, or synthetic plant growth regulators Methyur and Kamethur. The relationship between the chemical structure of new synthetic thienopyrimidine derivatives and their regulatory effect on the growth and photosynthesis of wheat plants was revealed. The most biologically active thienopyrimidine derivatives are proposed to be used as new synthetic physiological analogues of auxins and cytokinins to improve growth and increase photosynthesis of wheat (Triticum aestivum L.)variety Svitlana in the vegetative phase.
Nanoencapsulated Extracts from Leaves of Bauhinia forficata Link: In vitro Antioxidant, Toxicogenetic, and Hypoglycemic Activity Effects in Streptozotocin-induced Diabetic Mice
Published on: 5th September, 2024
In this study, we evaluated the assessed the hypoglycemiant, toxicogenetic and genotoxic effects of nanoencapsulate extracts of Bauhinia forficata Link. Phytochemical evaluations of extracts were carried out, as well as the evaluation using HPLC-MS and of antioxidant capacity in vitro. DM2 was induced in mice with streptozotocin and extracts were given orally for 28 days. That dried extract from infusion (ESIN) had a higher rate of bioactive compounds compared to the dried extract from decoction (ESDC), and higher antioxidant capacity. Glucose levels decreased from 77.26% to 57.79% and 45.15% after supplementation with ESIN (200 and 600 mg/kg/day) and ESDC (600 mg/kg/day), respectively, when compared to the diabetic group treated with metformin (600 mg/kg/day) (21.53%), with an improvement in the glycemic response e recovery of pancreatic β cells. Thus, our study has shown that these extracts exhibit hypoglycemiant activity, with a beneficial effect superior to metformin, as a result they could be considered as potential therapeutic agents for application in pharmaceutical formulations in the treatment of DM2.
The “Calcium Paradox” Due To Ca2+/Camp Interaction: New Insights for the Neuroscience Field
Published on: 21st February, 2017
OCLC Number/Unique Identifier: 7317597469
In the cardiovascular field, tachycardia and increment of catecholamine plasma levels (sympathetic hyperactivity) have been reported by hypertensive patients that use L-type Ca2+ channel blockers (CCBs) since 70´s. Our discovery of the involvement of interaction between the intracellular signalling pathways mediated by Ca2+ and cAMP (Ca2+/cAMP interaction) revealed that this phenomenon (sympathetic hyperactivity) was resulting of increase of transmitter release from sympathetic neurons stimulated by CCBs due to its interference on the Ca2+/cAMP interaction. In the neuroscience field, this discovery has produced new paths for the understanding of the cellular and molecular mechanisms involved in the pathogenesis of neurodegenerative diseases, such as Alzheimer´s and Parkinson’s diseases. In this way, novel journeys for the development of new pharmacological strategies more effective for the treatment of neurodegenerative diseases may be initiated.
Step VEP visual acuity in a pediatric neuro-ophthalmological cohort
Published on: 12th June, 2022
Steady-state VEPs, have been used to estimate visual acuity since the 1970s and allow responses to a range of stimulus sizes to be collected rapidly- with particular utility in infants. However, the assessment of children with cortical visual impairment is a bigger challenge that lead to the development of the Step VEP. Its initial evaluation revealed that accuracy and precision were poorer for pediatric patients than for optically degraded normal adults and that it was not necessarily successful in every child. Statistical models generated the equations: VAO = 0.56 VAStep (r2 = 0.75, F = 60.93, p = 0.000) and VAPL = 0.45 VAStep (r2 = 0.82, F = 156.85, p = 0.000), supported by a recent a systematic review of VA comparisons showing that recognition VA (optotypes) agrees more closely than discrimination VA (PL) with VEP VA. In combination, Step VEPS and subjective tests allowed complete assessment in 96% of patients, with incomplete Step VEPS much more likely to be partially successful than not, and more likely to be partially successful than incomplete subjective tests. This supports the rationale that Step VEPs maintain attention by limiting the time spent stimulating away from an individual’s threshold of spatial resolution. For the small number of patients in whom VA cannot be estimated, alternative stimuli and methods of presentation are proposed.
Incidental findings in traditional nuclear medicine practice

The presence of an incidental finding, defined as an abnormality which is unrelated to the initial scanning indication, is widely increases due to the access to new devices and imaging modalities. This growing number of incidental findings can lead to additional medical care including unnecessary tests nevertheless, in a minority of patients, can lead to diagnosis of an important and unexpected condition that could be crucial for the patient. We reported three cases in which nuclear medicine imaging, performed for different reasons and showed a relevant and unexpected pathology. In the case 1, a bone scan, performed in a 66 aged woman for breast cancer staging, allowed the diagnosis of a uterine fibroma. In the case 2, a HMPAO labeled-WBC scintigraphy performed because of a suspect of osteomyelitis, showed a remarkable heart-shaped photopenic area, highly suggestive of cardiac global dilatation. In the case 3, a 62 aged man referred to bone scintigraphy for the staging of recent diagnosed lung cancer. The bone scan allowed the diagnosis of a meningioma. Therefore, the occurrence of incidental findings could lead to reveal relevant abnormalities for the diagnostic pathway.

OCLC Number/Unique Identifier: 8501548256
Objective: Pregnancy after age 40 remains a concern as it exposes to particular obstetrical complications. Our study aims to determine the risks of complications related to pregnancy and childbirth of women aged 40 and over.
Study design: We carried out a cross-sectional analytical study of a historical cohort comparing the progress and the outcome of pregnancy in women 40 years of age and over to those aged 20 and 35 who gave birth at the University Hospital of Obstetrics and Gynecology in Befelatanana, from 1st January 2010 to 31 December 2013.
Results: The prevalence of childbirth among 40 years old and over was 0.61%. They were multiparous and large multiparous in 88% of the cases. The analysis showed that parturients aged 40 years and older were at significant risk for caesarean section, with three times the risk of emergency caesarean section. The frequency of this emergency caesarean section increased with parity ((RR = 3.04 [2.15-4.30], p = 10-10). Among their neonates, 23.42% were hypotrophic, 22.86% premature, 12% asphyxiated at birth, 13.14% admitted to neonatal resuscitation and 5.71% died in utero, but without significant difference with the group unexposed. Perinatal death was 7.43% in women aged 40 and over vs. 4% in 20 to 35 year olds ((RR = 1.85 [0,89-3,86]; p 0.052).
Conclusion: We found that pregnancies after 40 years were not exposed to pregnancy-related pathologies or specific fetal complications. The use of an emergency cesarean is, however, frequent.
Protective functions of AEURA in Cell Based Model of Stroke and Alzheimer disease
Published on: 6th June, 2017
OCLC Number/Unique Identifier: 7317651488
Stroke and neurodegenerative diseases including Alzheimer’s disease (AD) are responsible for a major proportion of mortalities in the elderly. We have previously investigated novel mechanism-based therapies of AEURA in cell culture models against viral infection and in glutamate excitotoxity. In our new studies, we propose that the homeopathic formula AEURA could serve as a potential therapeutic agent for stroke & for AD. In examining AEURA treatment of PC12 cells exposed to glutamate excitotoxicity, hypoxia /re-oxygenation injury and A-Beta toxicity. We demonstrated an increased survival rate in AEURA treated cells by comparison to control cells. In examining the therapeutic potential of AEURA in PC12 cells this homeopathic agent was found to be neuroprotective against either glutamate induced toxicity, hypoxia /re-oxygenation stress or cell stress resulting from viral infection (with either HSV-1 or rhinovirus). Our ongoing studies involve examining the neuroprotective potential AEURA in vivo using rodent models of stroke & AD.
