In efforts to record pathogenic fungal diversity on ornamental plants of Pakistan, infected leaves of Chlorophytum comosum plants were collected from commercial nursery in Lahore, Pakistan. Investigation of leafspot symptoms led to identification of an ascomycete fungus, Thielavia terrestris. Analysis for fungal identification involved morphological, microscopic and molecular methods. ITS-nrDNA sequence data were used to construct molecular phylogenetic tree of Thielavia with allied species. The fungus was confirmed as T. terrestris. This is the first report of T. terrestris causing disease in C. comosum and it is also a new record for Pakistan.
Peripheral blood eosinophilia is associated with a variety of benign and neoplastic conditions. Rarely, marked eosinophilia can mask an underlying Acute Leukaemia, delaying the correct diagnosis and treatment. Here, we report a case of 14-year-old boy, who presented with marked eosinophilia and space occupying lesion in the brain. Bone marrow biopsy and biopsy of brain lesion were performed to assess the underlying disorder, revealing the unexpected diagnosis of Precursor B- Acute Lymphoblastic Leukaemia in this patient. Cytogenetic studies revealed a normal male karyotype. This case highlights the significance of considering the rare possibility of Acute Lymphoblastic Leukaemia among the differential diagnosis of persistent eosinophilia in order to facilitate prompt and appropriate treatment.
Sensing and communication technology has been used successfully in various event monitoring applications over the last two decades, especially in places where long-term manual monitoring is infeasible. However, the major applicability of this technology was mostly limited to terrestrial environments. On the other hand, underwater wireless sensor networks (UWSNs) opens a new space for the remote monitoring of underwater species, faunas along with communicating with underwater vehicles, submarines etc. However, as opposed to terrestrial radio communication, underwater environment brings new challenges for reliable communication due to the high conductivity of the aqueous medium which leads to major signal absorption. In this paper, we provide a detailed technical overview of different underwater communication technologies, namely acoustic, magnetic and visual light, along with their potentials and challenges in submarine environments. Detailed comparison among these technologies have also been laid out along with their pros and cons using real experimental results.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
