Loss Of Activity-Induced Mitochondrial Atp Production Underlies The Synaptic Defects In A Drosophila Model Of Als, Nicholas E Karagas, Richa Gupta, Elham Rastegari, Kai Li Tan, Ho Hang Leung, Hugo J Bellen, Kartik Venkatachalam, Ching-On Wong

Faculty, Staff and Students Publications

Mutations in the gene encoding vesicle-associated membrane protein B (VAPB) cause a familial form of amyotrophic lateral sclerosis (ALS). Expression of an ALS-related variant of vapb (vapb^P58S) in Drosophila motor neurons results in morphologic changes at the larval neuromuscular junction (NMJ) characterized by the appearance of fewer, but larger, presynaptic boutons. Although diminished microtubule stability is known to underlie these morphologic changes, a mechanism for the loss of presynaptic microtubules has been lacking. By studying flies of both sexes, we demonstrate the suppression of vapb^P58S-induced changes in NMJ morphology by either a loss of endoplasmic …

BACKGROUND: Ductal carcinoma in situ (DCIS) is the most common type of in situ premalignant breast cancers. What drives DCIS to invasive breast cancer is unclear. Basal-like invasive breast cancers are aggressive. We have previously shown that NRAS is highly expressed selectively in basal-like subtypes of invasive breast cancers and can promote their growth and progression. In this study, we investigated whether NRAS expression at the DCIS stage can control transition from luminal DCIS to basal-like invasive breast cancers.

METHODS: Wilcoxon rank-sum test was performed to assess expression of NRAS in DCIS compared to invasive breast tumors in patients. NRAS …

Public Health Burden Of Secondhand Smoking: Case Reports Of Lung Cancer And A Literature Review, Ladislav Štěpánek, Jarmila Ševčíková, Dagmar Horáková, Mihir Sanjay Patel, Radka Durďáková

Faculty, Staff and Student Publications

Secondhand smoke (SHS), composed of mainstream and sidestream smoke, is a known human carcinogen. It contains a variety of harmful substances at even higher concentrations than mainstream smoke itself, which is inhaled during firsthand smoking. Exposure to SHS, affecting more than a third of the worldwide population, increases the likelihood of lung cancer by roughly 30%, with specific contributions depending on the histological type of cancer. This study aimed to present the harmful potential of SHS through case reports and describe the burden of SHS via a literature review. From a collection of lung cancer case reports occurring in never …

Center for Medical Ethics and Health Policy Staff Publications

Background: The diagnostic rate of Mendelian disorders in sequencing studies continues to increase, along with the pace of novel disease gene discovery. However, variant interpretation in novel genes not currently associated with disease is particularly challenging and strategies combining gene functional evidence with approaches that evaluate the phenotypic similarities between patients and model organisms have proven successful. A full spectrum of intolerance to loss-of-function variation has been previously described, providing evidence that gene essentiality should not be considered as a simple and fixed binary property.

Methods: Here we further dissected this spectrum by assessing the embryonic stage at which homozygous …

Maternal Gut Microbiota Mediate Intergenerational Effects Of High-Fat Diet On Descendant Social Behavior, Claudia M Di Gesù, Lisa M Matz, Ian J Bolding, Robert Fultz, Kristi L Hoffman, Antonella Marino Gammazza, Joseph F Petrosino, Shelly A Buffington

Faculty, Staff and Students Publications

Dysbiosis of the maternal gut microbiome during pregnancy is associated with adverse neurodevelopmental outcomes. We previously showed that maternal high-fat diet (MHFD) in mice induces gut dysbiosis, social dysfunction, and underlying synaptic plasticity deficits in male offspring (F1). Here, we reason that, if HFD-mediated changes in maternal gut microbiota drive offspring social deficits, then MHFD-induced dysbiosis in F1 female MHFD offspring would likewise impair F2 social behavior. Metataxonomic sequencing reveals reduced microbial richness among female F1 MHFD offspring. Despite recovery of microbial richness among MHFD-descendant F2 mice, they display social dysfunction. Post-weaning Limosilactobacillus reuteri treatment increases the abundance of short-chain …

From The Private Submissive Sphere To Public Intellectual Resistance: American Female Playwrights’ Contributions To Dramaturgy And Feminism, S. M. Al-Shraah, M. A. Alnwairan, A. A. Alkhawaldeh

Information Sciences Letters

This article joins a vibrant conversation in American literary studies about the contribution of female playwrights to dramaturgy as well as the feminist movement in the early twentieth century. In addition to assessing their contribution to American drama, the article extends the discussion to study how these female dramatists reflected the status of women in contemporary societies. We argue that the selected works of Susan Glaspell’s Trifles (1916) and Bernice (1917), Lorraine Hansberrys A Raisin in the Sun (1959), and Rachel Crothers’ A Mans World (1910) reveal a process, a transformation, a theatrical presentation of the development of female awareness …

Department of Medicine Faculty Papers

The impact of sex on pathophysiological processes, clinical presentation, treatment options, as well as outcomes of degenerative aortic stenosis remain poorly understood. Female patients are well represented in transfemoral aortic valve implantation (TAVI) trials and appear to derive favorable outcomes with TAVI. However, higher incidences of major bleeding, vascular complications, and stroke have been reported in women following TAVI. The anatomical characteristics and pathophysiological features of aortic stenosis in women might guide a tailored planning of the percutaneous approach. We highlight whether a sex-based TAVI management strategy might impact on clinical outcomes. This review aimed to evaluate the impact of …

BACKGROUND: Antimicrobial resistance is a global health threat. To slow resistance and preserve antibiotics, stewardship interventions are increasingly promoted and mandated. Urine cultures are the most common microbiological test in the outpatient setting. Contamination most likely occurs during urine collection from surrounding vaginal, perineal, and epidermal flora. Sample contamination can lead to incorrect diagnosis, unnecessary or inappropriate treatment, poor patient outcomes, and higher costs. Therefore, ensuring proper collection of urinary samples serves as a prime diagnostic stewardship target, one that international nursing societies increasingly endorse as an opportunity for nurse involvement.

OBJECTIVES: Determine the prevalence, predictors, and antibiotic prescribing associated …

In mammals, trait variation is often reported to be greater among males than females. However, to date, mainly only morphological traits have been studied. Energy expenditure represents the metabolic costs of multiple physical, physiological, and behavioral traits. Energy expenditure could exhibit particularly high greater male variation through a cumulative effect if those traits mostly exhibit greater male variation, or a lack of greater male variation if many of them do not. Sex differences in energy expenditure variation have been little explored. We analyzed a large database on energy expenditure in adult humans (1494 males and 3108 females) to investigate whether …
