0 vs 53.4 μg/g dry kidney weight). Importantly, diphenhydramine did not influence or interfere with the anti-tumor effect of cisplatin in any of the in vitro or in vivo experiments. In a selected cohort of 98 11 matched patients from a retrospective database of 1467 patients showed that patients with malignant cancer who had used diphenhydramine before cisplatin treatment exhibited significantly less acute kidney injury compared to ones who did not (6.1 % vs 22.4 %, respectively). Thus, diphenhydramine demonstrated efficacy as a novel preventive medicine against cisplatin-induced kidney toxicity.Mind wandering has been associated with both adaptive outcomes and performance impairment, depending on the context. Recently, non-invasive brain stimulation has been applied in several studies with the aim to investigate the neural region(s) casually involved in mind wandering. However, to date there has been little definitive work assessing whether or not the stimulation of different brain regions leads to distinct mind wandering outcomes. The present preregistered study considered the role of the prefrontal cortex and inferior parietal lobule in mind wandering using two stimulation intensities (1mA and 2mA) and two stimulation polarity montages. One-hundred and fifty subjects were randomly allocated to one of the four active stimulation groups or a sham group. Participants' mind wandering propensity was measured via a task unrelated thought probe dispersed throughout an attention-based task completed directly after stimulation. Anodal stimulation to the prefrontal cortex, and cathodal stimulation to the inferior parietal lobule, increased mind wandering propensity and this effect was relatively unaffected by stimulation dosage. ASP2215 in vitro These findings support a causal role for these two regions in mind wandering, one that is polarity specific.We investigated the neural basis of newly learned words in Spanish as a mother tongue (L1) and English as a second language (L2). Participants acquired new names for real but unfamiliar concepts in both languages over the course of two days. On day 3, they completed a semantic categorization task during fMRI scanning. The results revealed largely overlapping brain regions for newly learned words in Spanish and English. However, Spanish showed a heightened BOLD response within prefrontal cortex (PFC), due to increased competition of existing lexical representations. In contrast, English displayed higher activity than Spanish within primary auditory cortex, which suggests increased phonological processing due to more irregular phonological-orthographic mappings. Overall, these results suggest that novel words are learned similarly in Spanish L1 and English L2, and that they are represented in largely overlapping brain regions. However, they differ in terms of cognitive control and phonological processes.Humans often simultaneously pursue multiple plans at different time scales, a capacity known as prospective memory (PM). The successful realization of non-immediate plans (e.g., post package after work) requires keeping track of a future plan while accomplishing other intermediate tasks (e.g., write a paper). Prospective memory capacity requires the integration of noisy evidence from perceptual input with evidence from both short-term working memory (WM) and longer-term or episodic memory (LTM/EM). Here we formulate a set of empirical studies of prospective memory, all dual-task problems, as problems of computational rationality. We ask how a rational model should integrate noisy perceptual evidence and memory to maximize payoffs in these PM studies. The model combines reinforcement learning (optimal action selection) with evidence accumulation (optimal inference) in order to derive good decision parameters for optimal task performance (i.e., performing an ongoing task while monitoring for a cue that triggers executing a second prospective task). We compare model behavior to human behavioral evidence of key accuracy and reaction time phenomena in PM. Notably, our normative approach to theorizing and modeling these phenomena makes no assumptions about mechanisms of attention or retrieval. This approach can be extended to study the learning and use of meta-parameters governing the boundedly rational use of memory in planned action in health and disease. A computational psychiatry extension of the model can capture compensatory mnemonic strategies in neuropsychiatric disorders that may be rational responses to disturbances of inference, memory, and action selection.An insect's capacity to survive winter is critical for range expansion in temperate regions. The Asian longhorned beetle (Anoplophora glabripennis) is a polyphagous wood-boring insect native to China and the Korean peninsula and poses a high risk of invasion in North America and Europe. It is unclear whether A. glabripennis enters diapause, which means that diapause cannot be included in assessments of the risk of this species invading forests in temperate regions. Using a laboratory colony, we examine larval developmental arrest, metabolic rates, gas exchange patterns, thermal sensitivity, and body composition to characterize larval dormancy. Chilled larvae entered a temperature-independent developmental arrest which usually required more than four weeks of chilling to break, decreased their metabolic rate by as much as 63%, and maintained energy stores throughout the chilling period - results consistent with an obligate diapause. We also observed a switch to discontinuous gas exchange at low temperatures. Thermal sensitivity of metabolic rate did not differ between chilled and non-chilled larvae. Taken together, we conclude that A. glabripennis enters a larval diapause during chilling and terminates diapause after a requisite chilling period. These results will enhance our ability to predict phenology and potential distribution of current and future invasions of A. glabripennis.Globally, ascariasis ranks as the second leading intestinal helminth infection. However, progress in developing better control strategies, such as vaccines, remains slow-paced. This study aims to measure antibody production and parasite load in male BALB/c mice immunized with crude Ascaris suum intestinal tract homogenate. Thirty-two (32) mice were randomized into (1) unvaccinated, uninfected (UU); (2) unvaccinated, infected (UI); (3) vaccinated, uninfected (VU); and (4) vaccinated, infected (VI) groups. A 100-μL vaccine containing 50 μg of homogenized A. suum intestines and Complete Freund's Adjuvant (11) were introduced intraperitoneally. Immunizations were done on days 0, 10, and 20. Oral gavage with 1000 embryonated eggs was done on day 30. Blood was obtained at day 40. To measure serum IgG levels, indirect ELISA was done. Microtiter plates were coated with 100 μg larval homogenate, and HRP-conjugated anti-mouse IgG was used as secondary antibody. Parasite load was measured in lung and liver tissues. Tukey's HSD of signal to cut-off ratios of absorbance readings obtained in indirect ELISA procedure for the 1200 serum dilution showed statistically significant difference between the UU and VI (p = 0.
