Neuronal cell type specific roles for Nprl2 in neurodevelopmental disorder-relevant behaviors.

Loss of function in the subunits of the GTPase-activating protein (GAP) activity toward Rags-1 (GATOR1) complex, an amino-acid sensitive negative regulator of the mechanistic target of rapamycin complex 1 (mTORC1), is implicated in both genetic familial epilepsies and NDDs (Baldassari et al., 2018). Previous studies have found seizure phenotypes and increased activity resulting from conditional deletion of GATOR1 function from forebrain excitatory neurons (Yuskaitis et al.

Transforming grayscale MRI images to color utilizing generative artificial intelligence to better understand multiple sclerosis.

Multiple sclerosis (MS) falls within the spectrum of central nervous system (CNS) demyelinating diseases that may lead to permanent neurological disability. Fundamental to the diagnosis and clinical surveillance is magnetic resonance imaging (MRI) that allows for the identification of T2-hyperintensities associated with autoimmune injury that demonstrate distinct spatial distribution patterns. Here, we describe the clinical experience of a 31-year-old, right-handed, White man seen in consultation at The University of Texas Southwestern Medical Center in Dallas, Texas, following complaints of headaches that began after head trauma related to military service.

Education Research: The Neurohumanities in Training: Integrating a Humanities Curriculum Within Neurology Residency Programs.

Background And Objectives: Perhaps stemming from the central role of detailed examinations and a focus on the subjective sphere that grounds their clinical practice, neurologists have frequently opined on experiences traditionally a province of humanities. The increasingly technological focus on medical education and care can be seen to devalue the subjective aspects of medicine. As a counter to this, we report on the existence of neurohumanities curricula within neurology residency training.

Real-time CBCT imaging and motion tracking via a single arbitrarily-angled x-ray projection by a joint dynamic reconstruction and motion estimation (DREME) framework.

Real-time cone-beam computed tomography (CBCT) provides instantaneous visualization of patient anatomy for image guidance, motion tracking, and online treatment adaptation in radiotherapy. While many real-time imaging and motion tracking methods leveraged patient-specific prior information to alleviate under-sampling challenges and meet the temporal constraint (< 500 ms), the prior information can be outdated and introduce biases, thus compromising the imaging and motion tracking accuracy. To address this challenge, we developed a framework (DREME) for real-time CBCT imaging and motion estimation, without relying on patient-specific prior knowledge.

Clinical Perspectives on the Pathophysiology of Facial Synkinesis: A Narrative Review.

Importance: Facial synkinesis refers to pathologic cocontraction and baseline hypertonicity of muscles innervated by the facial nerve, commonly attributed to the aberrant regeneration of nerve fibers following injury. The pathomechanism and optimal treatment of facial synkinesis remain unclear. The goal of this review is to highlight current understanding of the epidemiology, pathophysiology, clinical presentation, assessment, and treatment of facial synkinesis.

Lung cancer-intrinsic SOX2 expression mediates resistance to checkpoint blockade therapy by inducing Treg cell-dependent CD8+ T-cell exclusion.

Tumor cell-intrinsic signaling pathways can drastically affect the tumor immune microenvironment, promoting tumor progression and resistance to immunotherapy by excluding immune-cell populations from the tumor. Several tumor cell-intrinsic pathways have been reported to modulate myeloid-cell and T-cell infiltration creating "cold" tumors. However, clinical evidence suggests that excluding cytotoxic T cells from the tumor core also mediates immune evasion.

Treatment strategies to reduce cardiovascular risk in persons with chronic kidney disease and Type 2 diabetes.

Chronic kidney disease (CKD) is a prevalent and progressive condition associated with significant mortality and morbidity. Diabetes is a common cause of CKD, and both diabetes and CKD increase the risk of cardiovascular disease (CVD), the leading cause of death in individuals with CKD. This review will discuss the importance of early detection of CKD and prompt pharmacological intervention to slow CKD progression and delay the development of CVD for improving outcomes.

Beyond cholangiocarcinoma: imaging features of mimicking pathologies in the biliary tract.

Cholangiocarcinoma (CCA) is the second most common primary malignancy of the hepatobiliary system and presents as a heterogeneous disease with three distinct morphological subtypes: mass-forming, periductal-infiltrating, and intraductal-growing, each characterized by distinguishing imaging features. Accurate diagnosis of CCA is challenging due to the overlap of imaging findings with a broad range of benign and malignant conditions. Therefore, it is essential for radiologists to recognize these mimickers and offer a reasonable differential diagnosis, as this has a significant impact on patient management.

Selenoprotein O Promotes Melanoma Metastasis and Regulates Mitochondrial Complex II Activity.

Evolutionarily conserved selenoprotein O (SELENOO) catalyzes a post-translational protein modification known as AMPylation that is essential for the oxidative stress response in bacteria and yeast. Given that oxidative stress experienced in the blood limits survival of metastasizing melanoma cells, SELENOO might be able to impact metastatic potential. However, further work is needed to elucidate the substrates and functional relevance of the mammalian homologue of SELENOO.

Structural mechanism of CBR binding to peripheral and biased inverse agonists.

The cannabinoid receptor 1 (CBR) regulates synaptic transmission in the central nervous system, but also has important roles in the peripheral organs controlling cellular metabolism. While earlier generations of brain penetrant CBR antagonists advanced to the clinic for their effective treatment of obesity, such molecules were ultimately shown to exhibit negative effects on central reward pathways that thwarted their further therapeutic development. The peripherally restricted CBR inverse agonists MRI-1867 and MRI-1891 represent a new generation of compounds that retain the metabolic benefits of CBR inhibitors while sparing the negative psychiatric effects.
