A Narrative Review Of Irritable Bowel Syndrome With Diarrhea: A Primer For Primary Care Providers, Baha Moshiree, Joel J Heidelbaugh, Gregory S Sayuk

2020-Current year OA Pubs

Irritable bowel syndrome with diarrhea (IBS-D) is a chronic disorder of gut-brain interaction, characterized by recurrent abdominal pain in association with more frequent, loose stools. The pathophysiology of irritable bowel syndrome (IBS) includes disordered gut motility, alterations in gut microbiota, neural-hormonal system abnormalities, immune reactivity, and visceral hypersensitivity. Timely diagnosis of IBS-D can be achieved easily using clinical criteria. Formal IBS diagnosis is important for optimizing treatment and patient outcomes and facilitating patient access to appropriate educational resources. Yet, given the symptom overlap with other gastrointestinal conditions, diagnosis of IBS-D often is perceived to be challenging. Treatment of IBS includes …

Accumulation Of Copy-Back Viral Genomes During Respiratory Syncytial Virus Infection Is Preceded By Diversification Of The Copy-Back Viral Genome Population Followed By Selection, Sébastien A Felt, Emna Achouri, Sydney R Faber, Carolina B López

2020-Current year OA Pubs

RNA viruses generate nonstandard viral genomes during their replication, including viral genomes of the copy-back (cbVGs) type that cannot replicate in the absence of a standard virus. cbVGs play a crucial role in shaping virus infection outcomes due to their ability to interfere with virus replication and induce strong immune responses. However, despite their critical role during infection, the principles that drive the selection and evolution of cbVGs within a virus population are poorly understood. As cbVGs are dependent on the virus replication machinery to be generated and replicated, we hypothesized that host factors that affect virus replication exert selective …

Gapdh Mediates Drug Resistance And Metabolism In Plasmodium Falciparum Malaria Parasites, Andrew J. Jezewski, Ann M. Guggisberg, Dana M. Hodge, Naomi Ghebremichael, Gavin Nicholas John, Lisa K. Mclellan, Audrey Ragan Odom John

2020-Current year OA Pubs

Efforts to control the global malaria health crisis are undermined by antimalarial resistance. Identifying mechanisms of resistance will uncover the underlying biology of the Plasmodium falciparum malaria parasites that allow evasion of our most promising therapeutics and may reveal new drug targets. We utilized fosmidomycin (FSM) as a chemical inhibitor of plastidial isoprenoid biosynthesis through the methylerythritol phosphate (MEP) pathway. We have thus identified an unusual metabolic regulation scheme in the malaria parasite through the essential glycolytic enzyme, glyceraldehyde 3-phosphate dehydrogenase (GAPDH). Two parallel genetic screens converged on independent but functionally analogous resistance alleles in GAPDH. Metabolic profiling of FSM-resistant …

Sleep-Promoting Neurons Remodel Their Response Properties To Calibrate Sleep Drive With Environmental Demands, Stephane Dissel, Markus K. Klose, Bruno Van Swinderen, Lijuan Cao, Melanie Ford, Erica M. Periandri, Joseph D. Jones, Zhaoyi Li, Paul J. Shaw

2020-Current year OA Pubs

Falling asleep at the wrong time can place an individual at risk of immediate physical harm. However, not sleeping degrades cognition and adaptive behavior. To understand how animals match sleep need with environmental demands, we used live-brain imaging to examine the physiological response properties of the dorsal fan-shaped body (dFB) following interventions that modify sleep (sleep deprivation, starvation, time-restricted feeding, memory consolidation) in Drosophila. We report that dFB neurons change their physiological response-properties to dopamine (DA) and allatostatin-A (AstA) in response to different types of waking. That is, dFB neurons are not simply passive components of a hard-wired circuit. Rather, …

Opioids Alter Paw Placement During Walking, Confounding Assessment Of Analgesic Efficacy In A Postsurgical Pain Model In Mice, Victoria E Brings, Maria A Payne, Robert W Gereau Iv

2020-Current year OA Pubs

Introduction: Hind paw-directed assays are commonly used to study the analgesic effects of opioids in mice. However, opioid-induced hyperlocomotion can obscure results of such assays.

Objectives: We aimed to overcome this potential confound by using gait analysis to observe hind paw usage during walking in mice.

Methods: We measured changes in the paw print area after induction of postsurgical pain (using the paw incision model) and treatment with oxycodone.

Results: Paw incision surgery reduced the paw print area of the injured hind paw as mice avoided placing the incised section of the paw on the floor. Surprisingly, oxycodone caused a …

Implications Of Conformational Flexibility, Lipid Binding, And Regulatory Domains In Cell-Traversal Protein Celtos For Apicomplexan Migration, Hirdesh Kumar, John R Jimah, Santosh A Misal, Nichole D Salinas, Michal Fried, Paul H Schlesinger, Niraj H Tolia

2020-Current year OA Pubs

Malaria and other apicomplexan-caused diseases affect millions of humans, agricultural animals, and pets. Cell traversal is a common feature used by multiple apicomplexan parasites to migrate through host cells and can be exploited to develop therapeutics against these deadly parasites. Here, we provide insights into the mechanism of the Cell-traversal protein for ookinetes and sporozoites (CelTOS), a conserved cell-traversal protein in apicomplexan parasites and malaria vaccine candidate. CelTOS has previously been shown to form pores in cell membranes to enable traversal of parasites through cells. We establish roles for the distinct protein regions of Plasmodium vivax CelTOS and examine the …

Clinical Trial Data Of Anti-Pd-1/Pd-L1 Therapy For Recurrent Or Metastatic Nasopharyngeal Carcinoma: A Review, Douglas R Adkins, Robert I. Haddad

2020-Current year OA Pubs

IMPORTANCE: Anti-programmed cell death receptor-1 (PD-1) therapy is standard of care for incurable recurrent or metastatic non-nasopharyngeal head and neck cancer. In contrast, there are no regulatory agency-approved anti-PD-1 agents indicated for the treatment of recurrent or metastatic nasopharyngeal carcinomas (RM-NPC) in the Western hemisphere, and no standard treatment option exists beyond first-line chemotherapy for RM-NPC. The pace of development of novel systemic therapy regimens for RM-NPC has been slow compared to many other advanced tumor types, leaving an unmet clinical need for these patients with a poor prognosis.

OBSERVATIONS: Recent clinical trials have documented the clinical activity of anti-PD-1 …
