Brotherhood and Hip-Hop: The Case of Chinese Hip-Hop Club Triple H

After hip-hop increased in popularity in Chinese entertainment programs, different perceptions of hip-hop in China reflected a clash of various thinking patterns among audiences, with hip-hop club Triple H on the cusp of controversy. Taking Triple H as a case study, this paper aims to explore how emotional attachments influence the development of Chinese hip-hop clubs in post-subculture. The findings indicated that the brotherhood rooted in hip-hop culture has been reshaped by the hybridity of Chinese hip-hop featuring fraternity mixed with sensitivity, loyalty filled with controversy, and heroism heightened by diversity. This paper argues that the recurring theme of “brotherhood” contributing to the charisma of Chinese hip-hop clubs cannot be partially interpreted as either gangster love or an underground bond, which gives rise to a new approach to the notion of authenticity, with hip-hop interpreted as a distinctive lifestyle.

Self-Assembled Triple (H+/O2−/e−) Conducting Nanocomposite of Ba-Co-Ce-Y-O into an Electrolyte for Semiconductor Ionic Fuel Cells

Triple (H+/O2−/e−) conducting oxides (TCOs) have been extensively investigated as the most promising cathode materials for solid oxide fuel cells (SOFCs) because of their excellent catalytic activity for oxygen reduction reaction (ORR) and fast proton transport. However, here we report a stable twin-perovskite nanocomposite Ba-Co-Ce-Y-O (BCCY) with triple conducting properties as a conducting accelerator in semiconductor ionic fuel cells (SIFCs) electrolytes. Self-assembled BCCY nanocomposite is prepared through a complexing sol–gel process. The composite consists of a cubic perovskite (Pm-3m) phase of BaCo0.9Ce0.01Y0.09O3-δ and a rhombohedral perovskite (R-3c) phase of BaCe0.78Y0.22O3-δ. A new semiconducting–ionic conducting composite electrolyte is prepared for SIFCs by the combination of BCCY and CeO2 (BCCY-CeO2). The fuel cell with the prepared electrolyte (400 μm in thickness) can deliver a remarkable peak power density of 1140 mW·cm−2 with a high open circuit voltage (OCV) of 1.15 V at 550 °C. The interface band energy alignment is employed to explain the suppression of electronic conduction in the electrolyte. The hybrid H+/O2− ions transport along the surfaces or grain boundaries is identified as a new way of ion conduction. The comprehensive analysis of the electrochemical properties indicates that BCCY can be applied in electrolyte, and has shown tremendous potential to improve ionic conductivity and electrochemical performance.

Evaluation Of Intra-Arterial Nimodipine Therapy In Post-Subarachnoid Hemorrhage Refractory Cerebral Vasospasm

Background: Cerebral vasospasm is a major cause of morbidity and mortality in patients with subarachnoid hemorrhage. Vasospasm is managed with triple H and vasodilators but sometimes, patients do not respond. Intra-arterial vasodilator infusion has been shown to improve outcome in such patients. In this study, we try to evaluate the efficacy of intra-arterial nimodipine therapy in 43 patients of post-aneurysmal subarachnoid hemorrhage refractory cerebral vasospasm. Methods: It is a prospective observational study of a group of 43 patients presenting with refractory cerebral vasospasm as per the inclusion criteria. Pre-procedure neurological assessment and Transcranial Doppler (TCD) monitoring were done. Endovascular spasmolysis was conducted and post-operative morbidity and outcomes were noted. Follow up of the patients was done at the time of discharge and at 6 months according to the Modified Rankin Scale and NCCT head. Results: Most of the patients developing refractory cerebral vasospasm belonged to Hunt and Hess Grade 2 and 3 and Fisher grade 3 and 4. 87.5% of the patients showed clinical recovery following endovascular spasmolysis and 58% of the patients showed complete angiographic recovery. Outcome after 6 months was good in 76%, moderate in 12% and poor in 12% patients. NCCT head showed no infarct in 58%, minor infarct in 28% and major vascular territorial infarct in 14% patients. Conclusions: Intra-arterial nimodipine infusion is a safe and effective therapy with minimum risk of complications if adhered to standard endovascular practice. By timely intervention, major ischemic insult to the brain can be averted, thereby significantly improving the prognosis.

Effects of hypothermia, hypoxia and hypercapnia on brain oxygenation and haemodynamic parameters during simulated avalanche burial - a porcine study

Avalanche patients who are completely buried but still able to breathe are exposed to hypothermia, hypoxia and hypercapnia (triple H syndrome). Little is known about how these pathologic changes affect brain physiology. Study aim was to investigate the effect of hypothermia, hypoxia and hypercapnia on brain oxygenation and systemic and cerebral haemodynamics. Anaesthetised pigs were surface-cooled to 28°C. Inspiratory oxygen (FiO2) was reduced to 17% and hypercapnia induced. Haemodynamic parameters and blood gas values were monitored. Cerebral measurements included cerebral perfusion pressure (CPP), brain tissue oxygen tension (PbtO2), cerebral venous oxygen saturation (ScvO2) and regional cerebral oxygenation saturation (rSO2). Tests were interrupted when haemodynamic instability occurred or 60 min after hypercapnia induction. ANOVA for repeated measures was used to compare values across phases. There was no clinically relevant reduction in cerebral oxygenation (PbtO2, ScvO2, rSO2) during hypothermia and initial FiO2 reduction. Hypercapnia was associated with an increase in pulmonary resistance followed by a decrease in cardiac output and CPP, resulting in haemodynamic instability and cerebral desaturation (decrease in PbtO2, ScvO2, rSO2). Hypercapnia may be the main cause of cardiovascular instability, which seems to be the major trigger for a decrease in cerebral oxygenation in triple H syndrome despite severe hypothermia.

Continous local Intra –arterial Nimodipine administration in severe symptomatic vasospasm after spontanous subarachnoid hemorrhage:a meta-analysis

Background Subarachnoid hemorrhage (SAH) is bleeding into the subarachnoid space (the area between the arachnoid membrane and the pia mater surrounding the brain). SAH is a potentially life threatening condition. Hemorrhage may occur as a result of a head injury or spontaneously (usually from a ruptured cerebral aneurysm). Spontaneous subarachnoid hemorrhage occurs in about one per 10,000 people per year. Females are more commonly affected than males. While it becomes more common with age, about 50% of people present under 55 years old. It is a form of stroke and comprises about 5 % of all strokes. Disturbed conscious level, specially that associated with cerebral arterial vasospasm, remains a major cause of death and disability in the patients with aneurysmal subarachnoid hemorrhage.The classical modality of management for vasospasm was oral calcium channel blockers (nimodipine) with triple-H therapy (Hypedynamic augmentation therapy). Aim To evaluate the effect of Continous local Intra –arterial nimodipine administration in severe symptomatic vasospasm after spontanous subarachnoid hemorrhage on mortality and morbidity (symptomtic cerebral ischemia). Methodology: Studies and participants In the current meta-analysis, we searched for interventional clinical trials in critically ill adult patients that evaluated to have aneurysmal subarachnoid hemorrhage complicated by severe symptomatic vasospasm (causing delayed cerebral ischemia and neurological deficits) which was refractory to standard hyper dynamic therapy (triple- H therapy) and oral calcium channel blockers (CCBS). Results In the current meta-analysis, the duration of infusion of nimodipine was at least for 72 hours. The onset of occurance of cerebral vasodilation after the infusion in all studies by their different doses was 12 hours detected by transcranial doppler. The time of termination of nimodipine infusion is different from patient to other patient depending on clinical improvement ( improvement of consious level or disappearance of the newly developed neurological deficit) and radiological findings that refers to the relief of vasospasm assesed by transcranial doppler and cerebral angiography. Reinfusion of the nimodipine was done in all included studies in case of recurrence of vasospasm causing new neurological deficit or deterioration in the conscious level . Conclusion It concluded from the current meta-analysis that, intra-arterial nimodipine infusion is effective and safe treatment for syptomatic refractory vasospasm after aneurysmal subarachnoid hemorrhage.
