An example of a D-metric space is given, in which D-metric convergence does not define a topology and in which a convergent sequence can have infinitely many limits. Certain methods for constructing D-metric spaces from a given metric space are developed and are used in constructing (1) an example of a D-metric space in which D-metric convergence defines a(More)
Examples of complete D-metric spaces are given in which every convergent sequence has at most two limits and in which there are convergent sequences with exactly two limits. Also an example of a complete D-metric space having a convergent sequence with infinitely many limits is given and, using the example, several fixed point theorems in D-metric spaces(More)
INTRODUCTION Petroclival meningiomas pose a major challenge to the treating neurosurgeon. The philosophy of treatment has changed over the decades from a nihilistic attitude to that of aggressive total excision to now a more tempered, maximal safe excision preventing morbidity followed by adjuvant treatment. Despite the advances in neurosurgery, surgical(More)
Glioblastoma is the most common malignant brain tumour, generated by bulk of malignant cancer stem cells, which express various stem cell factors like CD133, BMI1 and nestin. There are several studies which show the importance of CD133 in cancer, but the function and interaction with other major oncogenes and tumour suppressor genes is still not understood.(More)
Hypertension continues to be an important public health concern because of its associated morbidity, mortality and economic impact on the society. It is a significant risk factor for cardiovascular, cerebrovascular and renal complications. It has been estimated that by 2025, 1.56 billion individuals will have hypertension. The increasing prevalence of(More)
In the last decade synthesis of silver nanoparticles has been a subject of a lot of study and numerous methods are being developed for synthesis of nanoparticles of various shapes and sizes. Various biosynthetic strategies are being developed to employ biological sources such as fungi, bacteria, viruses, actinomycetes, algae and plant extracts to catalyze(More)
Vertebrates as is well known have been classified into Icthyopsida, Sauropsida and Mammals on the basis of structure of the eyes. Amongst, Aves like, Aquilla (Hawk), Bubo bubo (Indian Owl) were chosen for the study. The eye balls of Aquilla and Bubo Bubo were enucleated under anesthesia such as chloroform and fixed in 4% solution of formalin in 0.9% sodium(More)
