Ipsilateral corticospinal innervation is rare. No prior cases have described ipsilateral tumor-associated symptoms as the presentation of an uncrossed corticospinal tract. Herein, we describe a case associated with a left frontal tumor, presenting with transient ipsilateral hemiparesis and aphasia. Due to the fluctuating symptomatology, we suspected a cerebrovascular cause and initially performed a workup for stroke. Ipsilateral motor innervation was discovered with intraoperative monitoring during the resection of the tumor, and confirmed with postoperative diffusion tensor imaging (DTI). Neurosurgeons should be aware of uncrossed motor system, and include it in the differential of ipsilateral deficit in patients with intracranial tumors.Purpose We aimed to identify job accommodations that help persons with physical disabilities maintain or return to work and explore the barriers and facilitators that influence the provision and reception of job accommodations. Methods We conducted a systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The review was registered in PROSPERO (CRD42019129645). The search strategy incorporated keywords describing physical disabilities, employer-approved job accommodations, and employment retention or return to work approaches. We searched MEDLINE, the Cochrane Library, Embase, CINAHL, PsycINFO, Web of Science, and ProQuest Theses and dissertations. Reviewers independently selected studies for inclusion. We used Hawker et al.'s method to assess study quality. Results We identified 2203 articles, of which 52 met inclusion criteria, developed a table of job accommodations commonly used by persons with physical disabilities, summarized the percentages of job accommodations used by persons with disabilities, synthesized evidence of the effectiveness of job accommodations, and identified the factors that influence job accommodation use. The most frequently reported accommodations were as follows modification of job responsibilities, change of workplace policy, supportive personnel provision, flexible scheduling, and assistive technology. We summarized four types of facilitators and barriers that affect job accommodation use employee-related factors, accommodation-related factors, job-related factors, and social workplace-related factors. Conclusion The absence of randomized controlled trials and prevalence of cross-sectional surveys provides inconclusive evidence regarding the effectiveness of specific job accommodations for people with particular functional limitations. Our system of categorizing job accommodations provides a guide to investigators seeking to evaluate the effectiveness of job accommodations using experimental methods.The current linear no-threshold paradigm assumes that any exposure to ionizing radiation carries some risk, thus every effort should be made to maintain the exposures as low as possible. We examined whether background radiation impacts human longevity and cancer mortality. Our data covered the entire US population of the 3139 US counties, encompassing over 320 million people. IWP-4 mouse This is the first large-scale study which takes into account the two major sources of background radiation (terrestrial radiation and cosmic radiation), covering the entire US population. Here, we show that life expectancy, the most integrative index of population health, was approximately 2.5 years longer in people living in areas with a relatively high vs. low background radiation. (≥ 180 mrem/year and ≤ 100 mrem/year, respectively; p  less then  0.005; 95% confidence interval [CI]). This radiation-induced lifespan extension could to a great extent be associated with the decrease in cancer mortality rate observed for several common cancers (lung, pancreas and colon cancers for both genders, and brain and bladder cancers for males only; p  less then  0.05; 95% CI). Exposure to a high background radiation displays clear beneficial health effects in humans. These hormetic effects provide clear indications for re-considering the linear no-threshold paradigm, at least within the natural range of low-dose radiation.
Alternative splicing (AS) events were reportedly associated with the development of multiple cancers. The study was designed to provide a comprehensive analysis of AS events and explore their potential prognostic value in uveal melanoma (UM).

The prognostic AS events, identified based on the data of 80 UM patients obtained from The Cancer Genome Atlas, were further screened and analyzed for construction of prognostic signatures by using LASSO regression and multivariate Cox model. Kaplan-Meier survival analysis was used to evaluate the prognostic value. The AS events-related functional pathways were explored by gene set enrichment analysis (GSEA). The difference between two subgroups in terms of treatment options was investigated. The regulatory network between prognostic AS events and splicing factors (SFs) was then constructed.

A total of 1014 AS events were identified as prognostic AS events. Five prognostic AS events were involved in the construction of prognostic signatures, including AKAP2/87175/AP, RGMA/32575/ES, DNASE1L1/90581/ES, BIN1/55198/ES and ERCC2/50430/AT. UM patients were then divided into two subgroups. Prognostic AS signatures had an excellent performance in predicting the survival of UM patients, with an area under curve (AUC) of 0.962. GSEA results suggested several splicing-associated mechanisms, including cellular metabolic process and apoptosis. Low-risk subgroup could be more sensitive to drugs. A higher expression of immune checkpoint genes was observed in high-risk group than in low-risk group. SFs-AS regulatory network also revealed significant association between AS events and SFs.

Aberrant AS events in UM patients might serve as prognostic predictors.

Exposure to excess testosterone in women has been linked to several disorders, including kidney disorder and acting undoubtedly through androgen receptor (AR), whereas the involvement of mineralocorticoid receptor (MR) is unclear. Likewise, the renal effect of sodium acetate (SAc) during late gestational exposure to testosterone is not well known. We hypothesized that SAc or MR blockade would protect the kidney of testosterone-exposed pregnant rats against glutathione and adenosine depletion. Twenty-five pregnant Wistar rats were treated (sc) with olive oil, testosterone propionate (0.5 mg/kg) singly or in combination with SAc (200 mg/kg; p.o.), androgen receptor (AR) blocker, flutamide (Flu; 7.5 mg/kg; p.o.) or (MR) blocker, eplerenone (Eple; 0.5 mg/kg) between gestational days 14 and 19. Glutathione, adenosine and nitric oxide were decreased while uric acid (UA), xanthine oxidase (XO), malondialdehyde (MDA), lactate dehydrogenase activity and free fatty acids were increased in the kidneys of gestational rats exposed to testosterone.
