Review Study

Many researchers reported rates of infected dogs with T. canis and cats with Toxocara cati all over the world. The degree of tissue damage in the host and the concomitant elicitation of signs and symptoms are varied in different invaded tissues. The liver, lungs and central nervous system, including the eyes, are considered the most sensitive organs. In addition, the number of migrating juveniles and the age of the host. Inflammation manifests as eosinophilic granulomas. The immediate hypersensitivity responses to dying and dead larvae in the viscera, including the lungs, liver and brain, produce symptoms characteristic of VLM. The current review discusses the Toxocara sp. infection from the historical background, taxonomy, lifecycle, pathogeneses, clinical signs, epidemiology, diagnosis, control and treatment. And provides an overview of existing literature and data on the Toxocaraiasis with their references.

✓ Clinical and pathological features of 52 infants and children with atypical teratoid/rhabdoid tumor (ATT/RhT) of the central nervous system are defined. This tumor is typically misdiagnosed as a primitive neuroectodermal tumor (PNET) primarily because 70% of ATT/RhTs contain fields indistinguishable from classic PNETs. Separation of these two tumor types is crucial because the prognosis for ATT/RhT is grim even when treatment includes surgery with or without radio- and/or chemotherapy. These tumors are most common in infants less than 2 years of age. The cases described in this study arose intracranially in all but one instance, although one-third had already spread throughout the subarachnoid space at presentation. Clinical signs and symptoms and radiological features do not distinguish ATT/RhTs from PNETs. The tumors are composed entirely (13%) or partly (77%) of rhabdoid cells. Seventy percent contain fields of typical PNET alone or in combination with mesenchymal and/or epithelial elements. The immunohistochemical profile is unique: epithelial membrane antigen, vimentin, and smooth-muscle actin are positive in the majority of tumors and markers for germ-cell tumors are consistently negative. Abnormalities of chromosome 22 distinguish ATT/RhTs from PNETs, which typically display an i(17q) abnormality.

The current review is intended to highlight recent advances in the search of new and effective modulators of the metalloenzymes Carbonic Anhydrases (CAs, EC 4.2.1.1) expressed in humans (h). CAs reversibly catalyze the CO2 hydration reaction, which is of crucial importance in the regulation of a plethora of fundamental processes at cellular level as well as in complex organisms. The first section of this review will be dedicated to compounds acting as activators of the hCAs (CAAs) and their promising effects on central nervous system affecting pathologies mainly characterized from memory and learning impairments. The second part will focus on the emerging chemical classes acting as hCA inhibitors (CAIs) and their potential use for the treatment of diseases.

Novel Coronavirus

The vaccination for the novel Coronavirus (COVID-19) is undergoing its final stages of analysis and testing. It is an impressive feat under the circumstances that we are on the verge of a potential breakthrough vaccination. This will help reduce the stress for millions of people around the globe, helping to restore worldwide normalcy. In this review, the analysis looks into how the new branch of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) came into the forefront of the world like a pandemic. This review will break down the details of what COVID-19 is, the viral family it belongs to and its background of how this family of viruses alters bodily functions by attacking vital human respiratory organs, the circulatory system, the central nervous system and the gastrointestinal tract. This review also looks at the process a new drug analogue undergoes, from (i) being a promising lead compound to (ii) being released into the market, from the drug development and discovery stage right through to FDA approval and aftermarket research. This review also addresses viable reasoning as to why the SARS-CoV-2 vaccine may have taken much less time than normal in order for it to be released for use.

Central nervous system malignancies (CNSMs) are categorized among the most aggressive and deadly types of cancer. The low median survival in patients with CNSMs is partly explained by the objective difficulties of brain surgeries as well as by the acquired chemoresistance of CNSM cells. Flow Cytometry is an analytical technique with the ability to quantify cell phenotype and to categorize cell populations on the basis of their characteristics. In the current review, we summarize the Flow Cytometry methodologies that have been used to study different phenotypic aspects of CNSMs. These include DNA content analysis for the determination of malignancy status and phenotypic characterization, as well as the methodologies used during the development of novel therapeutic agents. We conclude with the historical and current utility of Flow Cytometry in the field, and we propose how we can exploit current and possible future methodologies in the battle against this dreadful type of malignancy.

The Central Nervous System

Menkes disease is a fatal neurodegenerative disorder arising from a systemic copper deficiency caused by loss-of-function mutations in a ubiquitously expressed copper transporter, ATP7A. Although this disorder reveals an essential role for copper in the developing human nervous system, the role of ATP7A in the pathogenesis of signs and symptoms in affected patients, including severe mental retardation, ataxia, and excitotoxic seizures, remains unknown. To directly examine the role of ATP7A within the central nervous system, we generated Atp7a Nes mice, in which the Atp7a gene was specifically deleted within neural and glial cell precursors without impairing systemic copper homeostasis, and compared these mice with the mottled brindle ( mo-br) mutant, a murine model of Menkes disease in which Atp7a is defective in all cells. Whereas mo-br mice displayed neurodegeneration, demyelination, and 100% mortality prior to weaning, the Atp7a Nes mice showed none of these phenotypes, exhibiting only mild sensorimotor deficits, increased anxiety, and susceptibility to NMDA-induced seizure. Our results indicate that the pathophysiology of severe neurological signs and symptoms in Menkes disease is the result of copper deficiency within the central nervous system secondary to impaired systemic copper homeostasis and does not arise from an intrinsic lack of ATP7A within the developing brain. Furthermore, the sensorimotor deficits, hypophagia, anxiety, and sensitivity to NMDA-induced seizure in the Atp7a Nes mice reveal unique autonomous requirements for ATP7A in the nervous system. Taken together, these data reveal essential roles for copper acquisition in the central nervous system in early development and suggest novel therapeutic approaches in affected patients.

Global Public Health Problem

Pandu Roga is one of the diseases mentioned in Ayurveda characterized by the changes in the skin colour to white (Shweta), yellowish (Peeta), greenish (Harita) etc. which is one of the “Varnopalakshita Roga" i.e., a disease characterized by the change in the colour. The clinical condition of Pandu in Ayurveda can be co-related with Anaemia described in Modern Medical Science, due to the resemblance in the clinical signs and symptoms. In Modern Medicine, Pandu is a pale appearance which may be due to the decreased blood supply to the skin or de- creased visibility of oxyhemoglobin. Anaemia is a major global public health problem and the most prevalent nu- tritional deficiency disorder in the world. This article presents the Ayurvedic concept of Pandu Roga (Anaemia).

Cryptococcus Spp

Canine cryptococcosis cases are typically reported as neurologic, disseminated, or both. There have been few reports of other parenchymal organ involvement. Dogs infected with Cryptococcus spp. are likely to develop central nervous system involvement, and those that are severely affected are treated aggressively with surgery and/or amphotericin B. This report describes two cases of canine abdominal cryptococcosis: one boxer with primary alimentary cryptococcosis alone and one miniature schnauzer with pancreatic and disseminated cryptococcosis. The boxer is unique in that the dog suffered from primary alimentary cryptococcosis without dissemination, secondary anemia due to gastrointestinal losses, and is the second case to have Cryptococcus spp. identified on fecal examination as part of the diagnostic workup. Unlike previous reports, surgery was not performed in either case, and both dogs were treated with fluconazole alone. Currently, both dogs are free from clinical signs, and Cryptococcus spp. antigen titers are negative at 17 and 15 mo after initial presentation. These cases suggest fluconazole may be effective therapy alone for canine abdominal cryptococcosis, negating the need for high-risk therapy options such as surgery and/or amphotericin B in some cases.

Csf Analysis

The medical records of 62 cats with clinical signs of central nervous system disease and accompanying inflammatory cerebrospinal fluid (CSF) analysis were examined retrospectively to determine if signalment, clinical signs, CSF analysis and ancillary testing could accurately predict the type of central nervous system disease that was present. An inflammatory CSF was defined as one in which a total nucleated cell count was greater than 5 cells/μl or one in which the total nucleated cell count was normal but the nucleated cell differential count was abnormal. Sex, degree of CSF inflammation, neuroanatomical location and systemic signs provided little contributory information to the final diagnosis. In 63% of the cases a presumptive diagnosis could be made based on a combination of clinical signs, clinicopathological data and ancillary diagnostic tests. CSF analysis alone was useful only in the diagnosis of cats with feline infectious peritonitis, Cryptococcus species infection, lymphoma and trauma. Overall, despite extensive diagnostic evaluation, a specific diagnosis could not be made in 37% of cats. The prognosis for cats with inflammatory CSF was poor with 77% of cats surviving less than 1 year.

Agrarian Communities

Organophosphate compounds are chemicals containing central phosphate molecules with alkyl or aromatic substituent’s. They occur in diverse forms and are used as pesticides, herbicides, nerve agents, etc. Organophosphate compounds are frequently used as pesticides in agrarian communities all across the world. South Asian countries such as Nepal use vast quantities of Organophosphate compounds for pest control in agriculture. Therefore, accidental and suicidal ingestion of Organophosphate compound poisoning has been common especially among the agricultural rural communities. Apart from muscarinic, nicotinic and central nervous system effects in rare instances, Organophosphate compounds are known to cause pancreatitis.
