Awareness of the Role of Nutrition in Cancer Causation and Prevention among Rural Adult Population: A Cross-sectional Study

Background In recent years, nutrition has received an increasingly important role in the aetiology of cancer. Thus, public education about dietary factors associated with cancer risk or prevention could be an important intervention for cancer prevention, particularly in low- and middle-income countries where the burden of cancer is increasing rapidly and access to care is limited. This study aimed to assess the awareness among rural adults about the role of nutrition in cancer development and its prevention. Methods A cross-sectional study was conducted among 300 individuals in the adult population (\u3e 18 years) in rural field practice area of a Medical College in South Karnataka for 3 months (June-August 2023) using a convenient sampling technique. Nutritional knowledge on cancer prevention was assessed using a semi-structured questionnaire which included sociodemographic details and multiple-choice questions. Data was entered in Microsoft Excel and analysed using descriptive and inferential statistics using SPSS V.26. Those who scored \u3e mean correct answer were considered as having good knowledge. Results Out of 300 study participants, 98% were aware of the disease of cancer, and 93% believed that nutrition played a role in cancer causation. 216 (72%) participants had good knowledge about role of nutrition in cancer causation and prevention whereas 84 (28%) had poor knowledge. A statistically significant association was observed between the participant’s age, religion and occupation with the knowledge level. Conclusion Majority of the participants had good knowledge about nutrition’s role in cancer causation and prevention

Successful maternal and fetal outcome in patients with Takayasu arteritis: two case reports of Type I and Type IV in stage 2

Takayasu's arteritis, is a rare, chronic, idiopathic, inflammatory disease of the large arteries, primarily involves the aorta, its main branches as well as the coronary and pulmonary arteries. It is mostly seen among women with child bearing age group (80%). During pregnancy, the increased intravascular volume impair circulation and exacerbate aortic regurgitation, hypertension, and congestive heart failure. Hypertension is one of the serious complication that can develop, leading to intrauterine growth restriction, maternal heart failure, and fetal haemorrhage and during postpartum period

Epithelioid leiomyosarcoma: a rare uterine cancer

A uterine epithelioid leiomyosarcoma is a rare malignant tumour that arises from the smooth muscle lining the walls of the uterus. The exact cause of leiomyosarcoma, including uterine leiomyosarcoma accounting for 5 to 10% is unknown. Leiomyosarcoma is the most common subtype of uterine sarcoma, accounts for 1-2% of uterine malignancies. Malignancy should be suspected in menopausal women with tumour growth who are not on hormonal replacement therapy. A 64-year-old female had attained menopause 16 year back and developed postmenopausal bleeding since 2 months, with palpable mass, of 16 weeks size. Ultrasonography showed whorled mass lesions, endometrium and myometrium could not be seen separately. Uterus with both ovaries removed. Intra-operative findings showed 16 weeks uterine mass with size 15×10.5×10cm and weight 1kg with intramural fibroid. Necrotic and haemorrhagic areas with degenerative changes seen on cut section suggestive of malignancy. Histopathology and immunohistochemistry reported epithelioid leiomyosarcoma

Cell wall composition in Cryptococcus neoformans is media dependent and alters host response, inducing protective immunity

INTRODUCTION: OBJECTIVE: The purpose of this study was to determine how different media influenced the amount of chitin and chitosan in the cell wall, which in turn impacted the cell wall architecture and host response. METHODS: Yeast extract, peptone, and dextrose (YPD) and yeast nitrogen base (YNB) are two commonly used media for growing Cryptococcus before use in in vitro or in vivo experiments. As a result, RESULTS: We observed that the growth of wild-type CONCLUSION: These findings emphasize the importance of culture media and pH during growth in shaping the content and organization of th

Cross talk between the Cell Wall Integrity and Cyclic AMP/Protein Kinase A pathways in Cryptococcus neoformans

Cryptococcus neoformans is a fungal pathogen of immunocompromised people that causes fatal meningitis. The fungal cell wall is essential to viability and pathogenesis of C. neoformans, and biosynthesis and repair of the wall is primarily controlled by the cell wall integrity (CWI) signaling pathway. Previous work has shown that deletion of genes encoding the four major kinases in the CWI signaling pathway, namely, PKC1, BCK1, MKK2, and MPK1 results in severe cell wall phenotypes, sensitivity to a variety of cell wall stressors, and for Mpk1, reduced virulence in a mouse model. Here, we examined the global transcriptional responses to gene deletions of BCK1, MKK2, and MPK1 compared to wild-type cells. We found that over 1,000 genes were differentially expressed in one or more of the deletion strains, with 115 genes differentially expressed in all three strains, many of which have been identified as genes regulated by the cyclic AMP (cAMP)/protein kinase A (PKA) pathway. Biochemical measurements of cAMP levels in the kinase deletion strains revealed significantly less cAMP in all of the deletion strains compared to the wild-type strain. The deletion strains also produced significantly smaller capsules than the wild-type KN99 strain did under capsule-inducing conditions, although the levels of capsule they shed were similar to those shed by the wild type. Finally, addition of exogenous cAMP led to reduced sensitivity to cell wall stress and restored surface capsule to levels near those of wild type. Thus, we have direct evidence of cross talk between the CWI and cAMP/PKA pathways that may have important implications for regulation of cell wall and capsule homeostasis

Autoclaves for Aerospace Applications: Issues and Challenges

The Council of Scientific and Industerial Research National Aerospace Laboratories (CSIR-NAL), Bangalore, India has been engaged in the research of autoclaves for the past three decades and has pioneered their development and usage in India for aerospace/aircraft structural applications. The autoclaves at CSIR-NAL have played a significant role in all the major national aircraft/aerospace programs. The largest aerospace autoclave in India (working size of 4.4 m diameter and 9.0 m length) has been successfully commissioned at CSIR-NAL. This paper gives the technological challenges faced and the innovative concepts that were introduced in these autoclaves

Perturbative calculation of quasi-normal modes of Schwarzschild black holes

We discuss a systematic method of analytically calculating the asymptotic form of quasi-normal frequencies of a four-dimensional Schwarzschild black hole by expanding around the zeroth-order approximation to the wave equation proposed by Motl and Neitzke. We obtain an explicit expression for the first-order correction and arbitrary spin. Our results are in agreement with the results from WKB and numerical analyses in the case of gravitational waves.Comment: 11 pages; references added and a sign error corrected; to appear in CQ
