Pakistan Journal of Neurological Sciences (PJNS)

Patients with aneurysmal Subarachnoid Hemorrhage (aSAH) frequently require Intensive Care Unit (ICU) beds, pre-operatively and more often, post-operatively due to the need for ventilatory support and specialized monitoring. We aimed to evaluate the frequency of post-operative ventilatory requirement in patients with aSAH and identify the possible predictive factors that might influence the need of post-operative ventilation in these patients. METHODS: We retrospectively identified a five-year data of all patients with aSAH who underwent surgical clipping using a structured proforma. Aneurysm was confirmed by Digital Subtraction Angiography (DSA) or Computerized Tomographic Angiography (CTA).

Distance Learning For Neurology: Experiences From Mini-Fellowship In Movement Disorders., Danish Bhatti, John Bertoni

Pakistan Journal of Neurological Sciences (PJNS)

Sub-speciality training in neurology is not available in Pakistan given lack of trained supervising faculty. Developing trained supervisors by sending faculty abroad for formal fellowships is too slow, resource intense and subject to attrition or brain-drain. Web-based learning methods have been used effectively in training in medicine. Meta-analysis of 201 eligible studies showed large positive effects of E-learning in health professionals compared with no interventions1. There are highly qualified academic neurologists available in developed countries of Pakistani origin providing opportunity to bridge the gap and transfer skills.

Department of Neurology Faculty Papers

Objective(s): In addition to pro-inflammatory role, dendritic cells (DCs) can also be anti-inflammatory when they acquire tolerogenic phenotype. In this study we tested the role of CD40 and IL-23p19 in antigen presenting function of bone marrow-derived DCs (BMDCs) by comparing BMDCs derived from CD40 knockout (CD40KO-DCs) and IL-23p19 (IL-23p19KO-DCs) knockout mice with those from C57BL/6 mice (Cont-DCs). We have focused on CD40 and IL-23, as these molecules have well established pro-inflammatory roles in a number of autoimmune and inflammatory diseases.

Materials and Methods: The expression of maturation markers MHC II and co-stimulatory molecules CD40, CD80, and CD86 was analyzed by …

Astronauts on interplanetary missions - such as to Mars - will be exposed to space radiation, a spectrum of highly-charged, fast-moving particles that includes ⁵⁶Fe and ²⁸Si. Earth-based preclinical studies show space radiation decreases rodent performance in low- and some high-level cognitive tasks. Given astronaut use of touchscreen platforms during training and space flight and given the ability of rodent touchscreen tasks to assess functional integrity of brain circuits and multiple cognitive domains in a non-aversive way, here we exposed 6-month-old C57BL/6J male mice to whole-body space radiation and subsequently assessed them on a touchscreen battery. Relative to …

Lymphocytes infiltrate the stroke core and penumbra and often exacerbate cellular injury. B cells, however, are lymphocytes that do not contribute to acute pathology but can support recovery. B cell adoptive transfer to mice reduced infarct volumes 3 and 7 d after transient middle cerebral artery occlusion (tMCAo), independent of changing immune populations in recipient mice. Testing a direct neurotrophic effect, B cells cocultured with mixed cortical cells protected neurons and maintained dendritic arborization after oxygen-glucose deprivation. Whole-brain volumetric serial two-photon tomography (STPT) and a custom-developed image analysis pipeline visualized and quantified poststroke B cell diapedesis throughout the brain, including …

Sanders-Brown Center on Aging Faculty Publications

Agglomerative hierarchical clustering analysis (HCA) is a commonly used unsupervised machine learning approach for identifying informative natural clusters of observations. HCA is performed by calculating a pairwise dissimilarity matrix and then clustering similar observations until all observations are grouped within a cluster. Verifying the empirical clusters produced by HCA is complex and not well studied in biomedical applications. Here, we demonstrate the comparability of a novel HCA technique with one that was used in previous biomedical applications while applying both techniques to plasma angiogenic (FGF, FLT, PIGF, Tie-2, VEGF, VEGF-D) and inflammatory (MMP1, MMP3, MMP9, IL8, TNFα) protein data to …
