Primary breast sarcoma: case report

Primary breast sarcoma is a rare entity occurring in 0.5% of women with breast malignancy. Like in breast carcinoma, delay in its diagnosis has important clinical and treatment implications. The subject of this report presented at our breast unit with advanced breast lesion months after she noticed a small lump in her right breast. She had no clear diagnosis despite several consultations, in-patient treatments at two facilities in the city, breast ultrasonography, breast mammography and three fine needle aspiration cytology (FNAC) examinations. The patient needed multiple blood transfusions. A final FNAC showed ductal carcinoma. Histology following wide excision confirmed high-grade primary stromal breast sarcoma. She required adjuvant combination chemotherapy. A combination of diagnostic failures and patient fault caused delay in subject's treatment. Lesion progression during delay which influenced the pattern of physical morbidity, tumour prognosis and need for adjuvant treatment. Embracing the concept of breast care in dedicated breast units may minimise such treatment delays. East African Medical Journal Vol.81(7) 2004: 375-37

Experiences of migrants from India living in Norway with COVID-19 Infodemic: A qualitative study

This qualitative study discusses the unique experiences of migrants from India in Norway, offering an in-depth exploration of their encounters with what has been called an “infodemic” during the COVID-19 pandemic. By conducting interviews with ten migrants and one general practitioner, this research aimed to comprehend the influence of exposure to transnational and sometimes contradictory information sources on health preserving behaviours and risk perceptions amidst the COVID-19 pandemic. Data was transcribed and analyzed using the Systematic Text Condensation method. The identified themes are i) Sources of Information, ii) Trust, Verification, and Local Authority in Health Information, iii) Informational Influences on Vaccination Decision-Making, iv) Healthcare Guidance: Balancing Local and Transnational Expertise, v) Emotional Impact and Coping Mechanisms. These findings highlight the complexities of information consumption and its effects on the cognitive-emotional processes of migrants, discussing the role of factors such as familiarity, emotional comfort, and trust. Further, the study identified the need for culturally sensitive health communication, the establishment of trust with migrant communities through accurate information dissemination, and the requirement of strategies to support the emotional well-being of migrants in situations when health information varies quickly and differ geographically. The implications of this research extend to the development of effective public health strategies for migrant communities during global health crisesM.Phil. in Global Health - ThesisINTH395AMAMD-GLO

Heteroepitaxial growth of ferromagnetic MnSb(0001) films on Ge/Si(111) virtual substrates

Molecular beam epitaxial growth of ferromagnetic MnSb(0001) has been achieved on high quality, fully relaxed Ge(111)/Si(111) virtual substrates grown by reduced pressure chemical vapor deposition. The epilayers were characterized using reflection high energy electron diffraction, synchrotron hard X-ray diffraction, X-ray photoemission spectroscopy, and magnetometry. The surface reconstructions, magnetic properties, crystalline quality, and strain relaxation behavior of the MnSb films are similar to those of MnSb grown on GaAs(111). In contrast to GaAs substrates, segregation of substrate atoms through the MnSb film does not occur, and alternative polymorphs of MnSb are absent

Face Location - A Novel Approach to Post the User global Location

Today Web users are facing the problems of information overload on the World Wide Web which stores vast source of data. As a result, how to provide Web users with more exactly needed information is becoming a critical issue in web based information . People populate more information on Social Network Sites as their profile data and etc. Now a days most of the users have accounts in social network sites. In this paper we are discussing the popular document classifiers to find the location of a user  in the social networking sites,In this paper we make use of the profile data and other information to achieve the objective of RRR which is to give Right information to the Right set of People at Right Time In this paper, we present Supervised learning: a method to cascade the decision tree learning methods in classifying locations of the users posted in a social network site.

Investigation of herbicide resistance in Japanese brome (Bromus japonicus) and responses of grain sorghum (Sorghum bicolor), & corn (Zea mays) to multiple herbicides at high-temperature stress

Master of ScienceDepartment of AgronomyMithila JugulamP.V. Vara PrasadWeed infestation poses a significant challenge to crop production. Post-emergence (POST) herbicides are commonly used to control weeds in crops including, wheat (Triticum aestivum L.), sorghum (Sorghum bicolor L. Moech), and maize or corn (Zea mays L.). Unfortunately, an inevitable consequence of the repeated and indiscriminate use of herbicides is the evolution of herbicide resistance in weeds. In the US, recently the first case of resistance to POST-applied acetolactate synthase (ALS)-inhibitor herbicides was found in Japanese brome (Bromus japonicus Thumb.), a problem weed in winter wheat (focus of Chapter 2). Although POST herbicides are excellent options for weed control, some of these herbicides are also known to cause crop injury, when exposed to abiotic stresses such as high-temperature (heat) stress, which was investigated in sorghum and corn (Chapters 3 and 4). The objectives of this thesis were to 1) confirm and characterize the ALS-inhibitor resistance in Japanese brome; 2) assess the response of grain sorghum to POST herbicides under high-temperature stress; and 3) evaluate corn response to POST herbicides under high-temperature stress. Experiments were conducted either in the greenhouse or in controlled environmental growth chambers. In objective 1, the level of resistance and mechanism of resistance to ALS-inhibitors were investigated in three Japanese brome populations, R1, R2 and R3. Results indicate ~ 167-, ~ 125-, and ~ 667-fold resistance to ALS-inhibitor, propoxycarbazone-Na in R1, R2, and R3, respectively, compared to a susceptible population. Additionally, mutations in the ALS gene resulting in amino acid substitutions i.e., Proline-197-Threonine in R3, R1 and Proline-197-Serine in R2, R1 were identified. The resistant populations also exhibited cross-resistance to other ALS-inhibitors, such as sulfosulfuron, mesosulfuron, pyroxsulam, and imazamox. Cross resistance to imazamox possibly via cytochrome P450 enzyme mediated metabolism was also found in R3 population. To achieve objective 2, grain sorghum genotypes, RTx430 and P84G62, were selected and grown in growth chambers maintained at two temperature regimes: optimum (OT: 32/22 °C; day/night (d/n)) and high-temperature (HT: 40/30 °C; d/n) and were treated separately with herbicides, e.g., 2,4-D, pyrasulfotole + bromoxynil, or mesotrione. Results revealed that at HT, grain sorghum is prone to more herbicide injury when treated with mesotrione or pyrasulfotole + bromoxynil but not with 2,4-D. Additionally, P84G62 had less injury compared to RTx430, irrespective of temperature or herbicide treatments. In objective 3, a similar experimental procedure was used, and corn genotype DKC59-82RIB, plants were grown at OT (30/25 °C; d/n) and HT (40/35 °C; d/n) and treated separately with 2,4-D, dicamba, mesotrione, tembotrione, or atrazine. The results indicate that at HT, corn plants exhibit more injury when treated with the above herbicides than at OT. Overall, the outcome of this research confirms alterations in the target site of ALS-inhibitors bestow resistance in Japanese brome. More importantly, the results also highlight that under HT stress, grain sorghum and corn are prone to POST-applied herbicide injury. These findings emphasize the necessity of sustainable weed management strategies amidst challenges like evolving herbicide resistance and changing climate conditions
