Complementary Therapy with Traditional Chinese Medicine for Ischemic Stroke

Stroke has remained the leading cause of morbidity or mortality worldwide over the past decade. Stroke survivors suffer various degrees of disability and also contribute to the large socioeconomic disease burden. Traditional Chinese medicine (TCM) serves as an important alternative or complementary therapy in many countries. This chapter aims to explore the utility of TCM for ischemic stroke, including a review of recent literature on the mechanisms of herbal medicine and acupuncture therapy on ischemic stroke, a summary of clinical trial results for the safety and efficacy of acupuncture, and finally a discussion of acupuncture as a preventive therapy for ischemic stroke in clinical practice. On the basis of these reports, more and more scientific evidences suggest that TCM use was safe for ischemic stroke at acute and subacute stages. Moreover, TCM has benefit for stroke recovery as well as it reduces the likelihood of hospital readmission for cardiovascular or subsequent stroke events

Phenotype-based and Self-learning Inter-individual Sleep Apnea Screening with a Level IV Monitoring System

Purpose: We propose a phenotype-based artificial intelligence system that can self-learn and is accurate for screening purposes, and test it on a Level IV monitoring system. Methods: Based on the physiological knowledge, we hypothesize that the phenotype information will allow us to find subjects from a well-annotated database that share similar sleep apnea patterns. Therefore, for a new-arriving subject, we can establish a prediction model from the existing database that is adaptive to the subject. We test the proposed algorithm on a database consisting of 62 subjects with the signals recorded from a Level IV wearable device measuring the thoracic and abdominal movements and the SpO2. Results: With the leave-one cross validation, the accuracy of the proposed algorithm to screen subjects with an apnea-hypopnea index greater or equal to 15 is 93.6%, the positive likelihood ratio is 6.8, and the negative likelihood ratio is 0.03. Conclusion: The results confirm the hypothesis and show that the proposed algorithm has great potential to screen patients with SAS

Light disrupts social memory via a retina-to-supraoptic nucleus circuit.

The formation of social memory between individuals of the opposite sex is crucial for expanding mating options or establishing monogamous pair bonding. A specialized neuronal circuit that regulates social memory could enhance an individuals mating opportunities and provide a parallel pathway for computing social behaviors. While the influence of light exposure on various forms of memory, such as fear and object memory, has been studied, its modulation of social recognition memory remains unclear. Here, we demonstrate that acute exposure to light impairs social recognition memory (SRM) in mice. Unlike sound and touch stimuli, light inhibits oxytocin neurons in the supraoptic nucleus (SON) via M1 SON-projecting intrinsically photosensitive retinal ganglion cells (ipRGCs) and GABAergic neurons in the perinuclear zone of the SON (pSON). We further show that optogenetic activation of SON oxytocin neurons using channelrhodopsin is sufficient to enhance SRM performance, even under light conditions. Our findings unveil a dedicated neuronal circuit through which luminance affects SRM, utilizing a non-image-forming visual pathway, distinct from the canonical modulatory role of the oxytocin system

Temperature trends ever the past five centuries reconstructed from borehole temperatures

For an accurate assessment of the relative roles of natural variability and anthropogenic influence in the Earth's climate, reconstructions of past temperatures from the pre-industrial as well as the industrial period are essential. But instrumental records are typically available for no more than the past 150 years. Therefore reconstructions of pre-industrial climate rely principally on traditional climate proxy records(1-5), each with particular strengths and limitations in representing climatic variability. Subsurface temperatures comprise an independent archive of past surface temperature changes that is complementary to both the instrumental record and the climate proxies. Here we use present-day temperatures in 616 boreholes from all continents except Antarctica to reconstruct century-long trends in temperatures over the past 500 years at global, hemispheric and continental scales. The results confirm the unusual warming of the twentieth century revealed by the instrumental record(6), but suggest that the cumulative change over the past five centuries amounts to about 1 K, exceeding recent estimates from conventional climate proxies(2-5). The strength of temperature reconstructions from boreholes lies in the detection of long-term trends, complementary to conventional climate proxies, but to obtain a complete picture of past warming, the differences between the approaches need to be investigated in detail.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/62610/1/403756a0.pd

THE EFFECTS OF QUADRICEPS TAPING AND NOWTAPING APPROCHES ON COUNTERMOVEMENT JUMP PERFORMANCE

Kinesio is one of the most common adhesive therapeutic tapes. Expect for clinical applications, kinesio claims to be able to enhance muscle activity performance. The purpose of this study was to investigate the effect of kinesio taping on quadriceps during a maximal counter-movement jump. Six healthy men was recruited in this study (Height: 173.8 k 4.2 em; Weight: 68.8 k 7.3 kg; Age: 22.9 k 2.3 yrs ). The kistler force plate was used to measure the jump height, takeoff force and landing force. No significant differences between two groups. The results showed that kinesio tape did not affect muscle activity and ground recreation force, jumping height and landing force

A Putative Cell Surface Receptor for White Spot Syndrome Virus Is a Member of a Transporter Superfamily

White spot syndrome virus (WSSV), a large enveloped DNA virus, can cause the most serious viral disease in shrimp and has a wide host range among crustaceans. In this study, we identified a surface protein, named glucose transporter 1 (Glut1), which could also interact with WSSV envelope protein, VP53A. Sequence analysis revealed that Glut1 is a member of a large superfamily of transporters and that it is most closely related to evolutionary branches of this superfamily, branches that function to transport this sugar. Tissue tropism analysis showed that Glut1 was constitutive and highly expressed in almost all organs. Glut1's localization in shrimp cells was further verified and so was its interaction with Penaeus monodon chitin-binding protein (PmCBP), which was itself identified to interact with an envelope protein complex formed by 11 WSSV envelope proteins. In vitro and in vivo neutralization experiments using synthetic peptide contained WSSV binding domain (WBD) showed that the WBD peptide could inhibit WSSV infection in primary cultured hemocytes and delay the mortality in shrimps challenged with WSSV. These findings have important implications for our understanding of WSSV entry

Electroacupuncture relieves portal hypertension by improving vascular angiogenesis and linking gut microbiota in bile duct ligation rats

The pathological increase in the intrahepatic resistance and decrease peripheral vascular tone in the development of portal hypertension (PHT). PHT has been linked to lower microbial diversity and weakened intestinal barrier, and interplay alters inflammatory signaling cascades. Electroacupuncture (EA) may ameliorate the inflammatory response and limit arterial vasodilatation and portal pressure. This study addresses the possible mechanisms underlying putative hemodynamics effects of EA in PHT rats. PHT was induced by bile duct ligation (BDL) over 7 days in rats. BDL rats were treated with low-frequency EA (2 Hz) at acupoint, ST36, 10 min once daily for 7 consecutive days. EA significantly reduced portal pressure and enhanced maximum contractile responses in the aorta, and blunts the angiogenesis cascade in PHT rats. EA decreased the aortic angiogenesis signaling cascade, reflected by downregulated of ICAM1, VCAM1, VEGFR1, and TGFβR2 levels. In addition, EA preserved claudin-1, occludin, and ZO-1 levels in BDL-induced PHT model. Furthermore, EA demonstrates to have a positive effect on the gut Bacteroidetes/Firmicutes ratio and to reduce pro-inflammatory cytokines and endotoxins. These results summarize the potential role of EA in the gut microbiota could potentially lead to attenuate intestine injury which could further contribute to vascular reactivity in PHT rats
