03 per 100 000. The 30-day mortality rate was 5% and the 30-day morbidity rate was 82%. Immediate surgical intervention was carried out in 36%, early surgical intervention in 56% and delayed surgical intervention in 8%.

The incidence of hollow viscus injury is in keeping with similar studies, but with lower mortality and higher morbidity. The rate of immediate or early surgical intervention was high. These findings are important to clinicians managing patients with major trauma and those involved in planning and allocation of resources.

Thus, the structural plasticity of the chains plays an important role in controlling the binding events. Herein, paramagnetic NMR spectroscopy is employed to explore the conformational space sampled by linear diubiquitin, a minimal unit of linear polyubiquitin, in its free state. Rigorous analysis of the data suggests that, regarding the relative positions of the ubiquitin units, particular regions of conformational space are preferentially sampled by the molecule. By combining these results with further data collected for charge-reversal derivatives of linear diubiquitin, structural insights into the factors underlying the binding events of linear diubiquitin are obtained.

The purpose of this systematic review is to evaluate the efficacy of antifibrinolytics in non-cardiac thoracic surgery.

We searched for all randomized controlled trials on this topic. A set of strict inclusion and exclusion criteria was developed. Six studies were meta-analysed together then in subgroups of topical tranexamic acid and intravenous aprotinin. We compared postoperative chest drain output, transfusions requirements and duration of hospital stay where available to determine the efficacy of topical tranexamic acid or intravenous aprotinin in reducing blood loss.

The use of antifibrinolytics reduces 24-h chest drain output (-290.21 mL [-524.75, -55.66], P= 0.02, I

= 98%), red blood cell transfusion requirements (-1.27 units [-2.24, -0.30], P= 0.01, I

= 100%) and shortened duration of hospital stay (-1.81 days [-3.25, -0.36], P= 0.01, I

= 96%). The subgroup analysis also supported this trend.

We conclude that the use of antifibrinolytics appears to reduce postoperative blood loss by reducing chest drain output, transfusion requirements and length of stay after thoracic surgery.

Metabolomics has considerable advantages in the analysis of small molecules and has been widely used in tea science. We applied a metabolomic method to evaluate the dynamic changes in metabolites and pathways in the large-, middle- and small-leaf cultivars of Camellia sinensis (L.) Kuntze var. niaowangensis grown in the same area from Yunwu Mountain. The results indicate that flavonoid biosynthesis, stilbenoid, diarylheptanoid and gingerol biosynthesis, citrate cycle (TCA cycle), and propanoate metabolism may play important roles in the differences among cultivars. The levels of tea polyphenols, flavonoids and amino acids may impact the sensory properties of teas of different cultivars. Our results may help to elucidate the mechanism underlying the difference in tea quality and offer references for the breeding of high-quality tea cultivars.Mg-air batteries are explored as the next-generation power systems for wearable and implantable electronics as they could work stably in neutral electrolytes and are also biocompatible. However, high corrosion rate and low utilization of Mg anode largely impair the performance of Mg-air battery with low discharge voltage, poor specific capacity and low energy density. Here, to the best of our knowledge, we first report a dual-layer gel electrolyte to simultaneously solve the above two problems by preventing the corrosion of Mg anode and the production of dense passive layer, respectively. The resulting Mg-air batteries produced an average specific capacity of 2190 mAh g-1 based on the total Mg anode (99.3 % utilization rate of Mg anode) and energy density of 2282 Wh kg-1 based on the total anode and air electrode, both of which are the highest among the reported Mg-air batteries. Besides, our Mg-air batteries could be made into a fiber shape, and they were flexible to work stably under various deformations such as bending and twisting.The serotonin (5-HT) system has been implicated in the pathophysiology of alcohol (ethanol; EtOH) use disorders. Lorcaserin, a 5-HT2C receptor agonist, attenuates drug self-administration in animal models. We investigated the effects of lorcaserin on EtOH intake using the drinking-in-the-dark (DID) procedure, an animal model of binge-like drinking. We compared the effects of lorcaserin to those of the Food and Drug Administration (FDA)-approved drug naltrexone and examined the effects of combining lorcaserin and naltrexone. To examine whether effects were specific for EtOH, we examined the effects of lorcaserin and naltrexone, administered alone and in combination, on saccharin intake. SN-38 Adult male C57BL/6J mice received EtOH access (20% v/v) for 2 h in the home-cage during the first 3 days of the DID procedure, beginning 3 h into the dark cycle. On day 4, mice were injected with lorcaserin, naltrexone, or a combination of lorcaserin and naltrexone prior to a 4-h EtOH access. Intake was measured at 2 and 4 h. Lorcaserin reduced EtOH intake in a dose-dependent fashion over the 2- and 4-h measurement periods. Naltrexone also reduced EtOH intake when administered alone, with dose-dependent effects being more pronounced over 2 h rather than the full 4-h session. Combining lorcaserin and naltrexone reduced binge-like EtOH drinking to a greater extent than either drug alone. A similar pattern of results was obtained for saccharin intake. These results suggest that lorcaserin and naltrexone can have additive effects on binge-like EtOH drinking. They also support continued research into the therapeutic potential of lorcaserin for alcohol use disorders.
