Changzhi Suffix Tonal Reduplication

In this paper, a floating tonal reduplicant suffix is proposed to re-analyze Changzhi Chinese suffix tone sandhi (Hou 1983), which has been presented as major evidence for Contour Tone Units (CTU). All stem contour tones in Changzhi, except one stem level tone, overwrite the underlying tone (HMH) of the adjectival and diminutive suffixes. In Yip (1980, 1989), this process was analyzed as spreading contour tones as units. The stem level tone was assumed to be assigned by a Default Tone Rule ordered after the tonal spreading rule. However, this CTU-based analysis has a problem of ordering paradox that derives incorrect outputs of the general disyllabic patterns. Combining with the primary concept of ‘tonal copying’ process proposed by Duanmu (1990, 1994), the framework of Base-Reduplicant Correspondence (McCarthy and Prince 1994, 1995) of Optimality Theory (Prince and Smolensky 1993/2004) has a more plausible explanation to Changzhi suffix tone sandhi. The OT analysis suggests that a floating tonal reduplicant T-RED accompanies the suffixes in Changzhi. The correspondence between the stem tonemes and T-RED is faithful, and the latter docks onto the suffixes whose underlying tonemes are then overwritten by this process. The stem level tone is not an exception; it undergoes the same reduplication process, but covertly, with the unchanged surface tonal sequence

Worldlikeness: A Web-based Tool for Typological Psycholinguistic Research

In this paper, we introduce Worldlikeness, a web-based tool for collecting and sharing cross-linguistic wordlikeness judgments (nonce word acceptability judgments) to facilitate typological psycholinguistic research. Typological psycholinguistic research is essential since crucial factors affecting language processing vary across languages, but these factors often too confounded to tease apart by comparing just two languages at a time. This type of research is nevertheless difficult since it requires testing many speakers from each language, using materials designed with the help of expert native speakers. Worldlikeness aims to make typological psycholinguistics more feasible, by providing tools for separate groups of experimenters to design experiments with text, audio, images, and video for individual languages, collect judgments and reaction times online, and crucially, share their data with each other for typological analysis. We show that Worldlikeness successfully replicated Mandarin wordlikeness judgments collected using traditional lab-based software, and report its first use in a cross-linguistic study collecting wordlikeness judgments from bilingual speakers of Mandarin and Southern Min

THE STUDY OF BATTING PERFORMANCE OF DIFFERENT MATERIAL BAT

The purpose of this study was to compare the velocity of sweet spot and batted-ball velocity during swing different material bat. Three collegiate baseball players randomly swung five different material bats. The high-speed video (2000 fps) was placed 7 meter above subject to capture swing image. The swing velocities of sweet spot before impact, after impact and batted-ball velocity were calculated. The results reveal that batted-ball velocity of bamboo bat and compound bat were between alloy bat and wood bat. There are significant correlations among bat velocity before impact and batted-ball velocity. We suggest that the bamboo or synthetic material of wood and bamboo were suitable to produce baseball bat. Moreover, it is very economy and safer than alloy bat

Regulation of CLC-1 chloride channel biosynthesis by FKBP8 and Hsp90β.

Mutations in human CLC-1 chloride channel are associated with the skeletal muscle disorder myotonia congenita. The disease-causing mutant A531V manifests enhanced proteasomal degradation of CLC-1. We recently found that CLC-1 degradation is mediated by cullin 4 ubiquitin ligase complex. It is currently unclear how quality control and protein degradation systems coordinate with each other to process the biosynthesis of CLC-1. Herein we aim to ascertain the molecular nature of the protein quality control system for CLC-1. We identified three CLC-1-interacting proteins that are well-known heat shock protein 90 (Hsp90)-associated co-chaperones: FK506-binding protein 8 (FKBP8), activator of Hsp90 ATPase homolog 1 (Aha1), and Hsp70/Hsp90 organizing protein (HOP). These co-chaperones promote both the protein level and the functional expression of CLC-1 wild-type and A531V mutant. CLC-1 biosynthesis is also facilitated by the molecular chaperones Hsc70 and Hsp90β. The protein stability of CLC-1 is notably increased by FKBP8 and the Hsp90β inhibitor 17-allylamino-17-demethoxygeldanamycin (17-AAG) that substantially suppresses cullin 4 expression. We further confirmed that cullin 4 may interact with Hsp90β and FKBP8. Our data are consistent with the idea that FKBP8 and Hsp90β play an essential role in the late phase of CLC-1 quality control by dynamically coordinating protein folding and degradation

Differential regulation of morphine antinociceptive effects by endogenous enkephalinergic system in the forebrain of mice

<p>Abstract</p> <p>Background</p> <p>Mice lacking the preproenkephalin (<it>ppENK</it>) gene are hyperalgesic and show more anxiety and aggression than wild-type (WT) mice. The marked behavioral changes in <it>ppENK </it>knock-out (KO) mice appeared to occur in supraspinal response to painful stimuli. However the functional role of enkephalins in the supraspinal nociceptive processing and their underlying mechanism is not clear. The aim of present study was to compare supraspinal nociceptive and morphine antinociceptive responses between WT and <it>ppENK </it>KO mice.</p> <p>Results</p> <p>The genotypes of bred KO mice were confirmed by PCR. Met-enkephalin immunoreactive neurons were labeled in the caudate-putamen, intermediated part of lateral septum, lateral globus pallidus, intermediated part of lateral septum, hypothalamus, and amygdala of WT mice. Met-enkephalin immunoreactive neurons were not found in the same brain areas in KO mice. Tail withdrawal and von Frey test results did not differ between WT and KO mice. KO mice had shorter latency to start paw licking than WT mice in the hot plate test. The maximal percent effect of morphine treatments (5 mg/kg and 10 mg/kg, i.p.) differed between WT and KO mice in hot plate test. The current source density (CSD) profiles evoked by peripheral noxious stimuli in the primary somatosenstory cortex (S1) and anterior cingulate cortex (ACC) were similar in WT and KO mice. After morphine injection, the amplitude of the laser-evoked sink currents was decreased in S1 while the amplitude of electrical-evoked sink currents was increased in the ACC. These differential morphine effects in S1 and ACC were enhanced in KO mice. Facilitation of synaptic currents in the ACC is mediated by GABA inhibitory interneurons in the local circuitry. Percent increases in opioid receptor binding in S1 and ACC were 5.1% and 5.8%, respectively.</p> <p>Conclusion</p> <p>The present results indicate that the endogenous enkephalin system is not involved in acute nociceptive transmission in the spinal cord, S1, and ACC. However, morphine preferentially suppressed supraspinal related nociceptive behavior in KO mice. This effect was reflected in the potentiated differential effects of morphine in the S1 and ACC in KO mice. This potentiation may be due to an up-regulation of opioid receptors. Thus these findings strongly suggest an antagonistic interaction between the endogenous enkephalinergic system and exogenous opioid analgesic actions in the supraspinal brain structures.</p

Recurrent stress cardiomyopathy with different electrocardiographic abnormalities on each presentation in a depressed post-menopausal woman

AbstractStress cardiomyopathy (SCM) is a syndrome of transient cardiac abnormalities precipitated by intense emotional or physical stress. Differentiating SCM from acute myocardial infarction is often difficult but vital to avoid subjecting SCM patients to unnecessary reperfusion therapy and invasive coronary angiography. For accurate diagnosis, it is important that physicians be familiar with the current diagnostic criteria, most susceptible populations, and typical triggers for SCM. SCM occurs almost exclusively in post-menopausal women, a group with a high frequency of psychiatric disorders. Thus, in addition to typical trigger events, comorbid psychiatric disorders may contribute to SCM onset. We report a rare case of recurrent SCM with distinct electrocardiographic abnormalities during each presentation in a post-menopausal woman with depression.<Learning objective: Recurrence of SCM was thought to be infrequent before but it has been increasingly reported recently. Although the underlying mechanism remains unclear, comorbid psychiatric disorders may contribute significantly to the pathogenesis of SCM and its influence may have been underestimated. Routine mental health screening should be done accompanying therapy for SCM.

Dynamic reciprocal relationships between traditional media reports, social media postings, and youth suicide in Taiwan between 2012 and 2021

Rising social media use over the past decade has been linked with increasing suicide rates among young people. Previous studies that assessed the impact of social media on suicide have typically focused on single social media platforms, such as Twitter, and assumed unidirectional associations, where social media posts leads to suicide. Our study focused on the past decade (2012–2021) which has witnessed a rapid increase of social media platforms and use. Poisson and negative binominal auto-regression models were employed to examine the dynamic reciprocity between social media, traditional media and youth suicides in Taiwan. Increased volume in suicide-related social media posts positively correlated with increased youth suicide rates (β = 2.53 × 10-5, 95% CI= (0.83 × 10-5, 4.24 × 10-5), P < 0.01), but increased rates of youth suicide was not related to an increase in suicide-related social media posts. Suicide-related posts on social media triggered reporting of suicide-related news on traditional media platforms (β = 3.35 × 10-2, 95% CI= (2.51 × 10-2, 4.19 × 10-2), P < 0.001), whilst traditional media reports of suicide led to increased suicide-related social media posts (β = 6.13 × 10-1, 95% CI = (4.58 × 10-1, 7.68 × 10-1); P < 0.001). However, suicide-related reports on traditional media platforms did not directly lead to an increase in youth suicide rates. Our findings highlight challenges for suicide prevention strategies in the 21st Century, in dealing with the increasing prominence of social media over traditional media. As social media is more difficult to regulate than traditional media, suicide prevention efforts must adapt to this new landscape by developing innovative strategies that address the unique risks and opportunities presented by social media

Perioperative Stroke Following General Surgery

AbstractPerioperative stroke is rare; however, patients undergoing cardiovascular surgery are considered to be at high risk for perioperative stroke. Here, we outline a case where perioperative stroke occurred following total hip replacement surgery. The risk factors and possible causes of the stroke in this patient are discussed. In addition, we reiterate the appropriate management approaches needed to prevent perioperative stroke. Briefly, the importance of precise preoperative evaluation and of proper intraoperative and postoperative management should not be overlooked. Finally, it is important to realize that decreasing perioperative strokes and the disabilities associated with them will lower the financial burden on families and the community

Acute Viral Hepatitis C-Induced Jaundice in Pregnancy

SummaryObjectiveAcute viral hepatitis C-induced jaundice in pregnancy is very rare and may be fatal. Here, we report a complicated case with acute hepatitis C-induced jaundice in pregnancy with successful managementCase ReportA 27-year-old pregnant woman, gravida 2, para 1, with gestational age of 36 weeks and 5 days, was referred to our hospital due to jaundice and elevated liver enzymes of undetermined cause. She had been suffering from general weakness, diarrhea and vomiting for 1 week, and jaundice with tea-colored urine for 3 days. At our medical center, acute viral hepatitis C-induced jaundice was suspected. Since her general condition deteriorated at 36 weeks and 6 days of gestation, we decided to induce labor. A male baby was born smoothly via the vaginal route, with birth weight 2,857 g, birth length 48.6 cm, and 1- and 5-minute Apgar scores of 7 and 9, respectively. Maternal condition improved dramatically after delivery and her serum liver enzymes and bilirubin levels gradually approached normal ranges.ConclusionMothers and fetuses with acute viral hepatitis C-induced jaundice during pregnancy are at great risk of mortality and morbidity. Timely termination may be one of the choices of treatment when fetal maturity has been reached and the maternal condition has deteriorated

Tension Pneumoperitoneum Following Upper Gastrointestinal Endoscopy

Tension pneumoperitoneum is a potentially lethal complication of numerous iatrogenic procedures, including upper gastrointestinal (UGI) endoscopy. We report a 69-year-old man with UGI bleeding who developed tension pneumoperitoneum and cardiac arrest after UGI endoscopy. He was successfully resuscitated with needle decompression. Emergency surgery revealed a perforated gastric ulcer, and subtotal gastrectomy with Billroth II anastomosis was performed. Recovery was smooth and he was discharged from the hospital 18 days later. Tension pneumoperitoneum should be suspected in all patients who develop circulatory collapse with acutely distended abdomen after UGI endoscopy. Early identification relies on a high index of suspicion. Prompt treatment with needle decompression should not be delayed for confirmatory radiography once the clinical diagnosis is made
