Contrasting to the established role of the hypothalamic agouti-related protein (AgRP) neurons in feeding regulation, the neural circuit and signaling mechanisms by which they control energy expenditure remains unclear. Here, we report that energy expenditure is regulated by a subgroup of AgRP neurons that send non-collateral projections to neurons within the dorsal lateral part of dorsal raphe nucleus (dlDRN) expressing the melanocortin 4 receptor (MC4R), which in turn innervate nearby serotonergic (5-HT) neurons. Genetic manipulations reveal a bi-directional control of energy expenditure by this circuit without affecting food intake. Fiber photometry and electrophysiological results indicate that the thermo-sensing MC4RdlDRN neurons …

Communication Sciences and Disorders Faculty Articles and Research

Affective prosody, or the changes in rate, rhythm, pitch, and loudness that convey emotion, has long been implicated as a function of the right hemisphere (RH), yet there is a dearth of literature identifying the specific neural regions associated with its processing. The current systematic review aimed to evaluate the evidence on affective prosody localization in the RH. One hundred and ninety articles from 1970 to February 2020 investigating affective prosody comprehension and production in patients with focal brain damage were identified via database searches. Eleven articles met inclusion criteria, passed quality reviews, and were analyzed for affective prosody localization. …

Upregulation of voltage-gated sodium channels (VGSCs) and Na+/K+-ATPase (sodium pumps) is common across most malignant carcinomas. Targeted osmotic lysis (TOL) is a developing technology in which the concomitant stimulation of VGSCs and pharmacological blockade of sodium pumps causes rapid selective osmotic lysis of carcinoma cells. This treatment of cervical carcinoma is evidence that TOL is a safe, well-tolerated and effective treatment for aggressive advanced carcinomas that has the potential to extend life without compromising its quality. TOL is likely to have broad application for the treatment of advanced-stage carcinomas.

Post-Operative Seizure Control In Patients With Glioblastoma, Ummey Hani, Muhammad Ammar Haider, Saqib Kamran Bakhshi, Muhammad Shahzad Shamim

Section of Neurosurgery

While the median survival in patients with glioblastoma has not improved significantly over the past decade, aggressive attempts have been made on palliation and improving quality of life in these patients. A confluence of two debilitating pathologies which massively distorts the normal day-to-day functioning of the patients who experience it, seizures in glioblastoma patients portends a poor prognosis. There exists a paucity of reported seizure outcomes after glioblastoma treatment in neurosurgical literature. Herein we present a review examining post-operative seizure control in patients with glioblastoma.

Neurological Associations Of Covid-19 Vaccines, Rija Zehra Ghazanfar, Mohammad Wasay

Pakistan Journal of Neurological Sciences (PJNS)

It does not come as a surprise that the introduction of an unprecedented treatment for a recently notorious disease will cause concerns and raise some questions. As a race we have become cautious over the centuries about what treatment modalities we accept and reject. With the advent of social media and endless sources of information we find ourselves standing at an intersection of many pathways, thinking meticulously where to go from there? At one point the widely available stats and the complex way in which these vaccines work do not really interest the general population as much as how they …

Anti-Nmda Receptor Encephalitis, Zaid Waqar, Haris Majid Rajput, Muhammad Hassan, Iqra Athar, Neelma Naz Khattak, Mazhar Badshah

Pakistan Journal of Neurological Sciences (PJNS)

Anti N-methyl-D-aspartate receptor (NMDA)receptor encephalitis is one of the most common type of auto immune encephalitis. Its diagnosis is often delayed due to initial clinical presentation with psychiatric clinical features. Initial clinical features resemble those of acute psychosis or depression which later evolve into frank neurological dysfunction. This was first described in association with ovarian teratoma, but it was later also found to exist without neoplastic association and in men as well. It occurs more frequently in younger age group, mostly below 50 years of age. Diagnosis is established with the help of cerebrospinal fluid (CSF) analysis for oligo clonal …

Early Neurological Deterioration After Acute Stroke; Mechanism And Predictors, Bushra Ammad Taimuri, Sajid Hameed, Mohammad Wasay

Pakistan Journal of Neurological Sciences (PJNS)

Neurological deterioration after acute ischemic stroke (AIS)is a common occurrence, leading to increased mortality, morbidity, and poor quality of life among stroke survivors. Recognition of the individuals at a greater risk for neurological deterioration may contribute to making early decisions and monitoring the therapy. Neurological deterioration arises in up to 40% of subjects after AIS during hospitalization and is followed by neurological and functional debility. Numerous predictors have been devised that predict this progression. This includes preliminary assessment of the severity of stroke, brainstem infarction, hyperglycemia, atrial fibrillation, diabetes mellitus and substantial fluctuations in blood pressure. Sequential observations, in depth …

Migraine And Fasting, Lubna Ashraf Jafri, Mohammad Wasay

Pakistan Journal of Neurological Sciences (PJNS)

Migraine is considered as the second leading cause of disability worldwide, most commonly seen in young women. Skipping meals, dehydration and fasting are among many triggering factors which have been described in literature as a cause of increased frequency and severity of migraine attacks. The underlying pathophysiology, prevention and management of fasting induced migraine has been documented, however, there is a lack of randomized controlled trials for the same. This review article discusses these important aspects in the light of published literature and gives directions on future areas of research.

Machine Learning Classification Of Traumatic Brain Injury Patients Versus Healthy Controls Using Arterial Spin Labeled Perfusion Mri, Vanessa I. Grass 2021 CUNY Graduate Center

Machine Learning Classification Of Traumatic Brain Injury Patients Versus Healthy Controls Using Arterial Spin Labeled Perfusion Mri, Vanessa I. Grass

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) is one of the most common causes of death and disability worldwide, yet accurate in vivo detection of TBI neuropathology remains challenging due to complexities in the structural and functional changes observed post-injury as well as limitations in conventional neuroimaging modalities. Although advanced neuroimaging techniques such as arterial spin labeling (ASL) can noninvasively assess cerebral blood flow (CBF) changes observed post-injury, this technique is underutilized in TBI research partly due to the low signal-to-noise-ratio (SNR) inherent in ASL imaging. The aim of the current study is to examine the use of machine learning, specifically a Support …
