Background： Rumen microbiome has a great influence on ruminant health and productivity. Different plant extracts have been tested for their ability to modulate the rumen microbiome to improve feed digestion and fermentation. Among the evaluated plant extracts, essential oils, tannins, and saponins appeared to have positive effects on rumen protein metabolism, volatile fatty acids production, and methane and ammonia production. Methods： The objective of this study was to evaluate the effect of rosemary （Rosmarinus officinalis L.） leaves and essential oils on rumen microbial populations. Four ruminally cannulated sheep were used in a 4x4 Latin square design fed （21 d/period）： 1） a control diet composed of alfalfa hay and concentrate pellet （CTR）, 2） CTR supplemented with 7 g/d/sheep of rosemary essential oil adsorbed on an inert support （EO）, 3） CTR with 10 g/d/sheep of dried and ground rosemary leaves （RL）, and 4） CTR with 10 g/d of dried and ground rosemary leaves pelleted into concentrate （RL pellet）. Abundance of total bacteria, archaea, protozoa, and some select bacterial species or groups was quantified using qPCR, while the community of bacteria and archaea was profiled using denaturing gradient gel electrophoresis. Results： No difference in abundance was noted for total bacteria, protozoa, or Rurninococcus flavefaciens between the control and the treatments, but the rosemary leaves, either in loose form or in pellet, decreased the abundance of archaea and the genus Prevotello （P 〈 0.001）. The rosemary leaves in loose form also decreased （P 〈 0.001） the abundance of Ruminococcus albus and Clostridium aminophilum, while the EO increased （P 〈 0.001） the abundance of Fibrobocter sucdnogenes. The community of bacteria and archaea was not affected by any of the supplements. Conclusions： Being able to affect the abundance of several groups of rumen microbes that are known to be involved in degradation of protein and fiber and production of methane and ammonia, rosema

We read with great interest the article of Rodriguez et al.,"Which method of distal pancreatectomy is cost-effective among open,laparoscopic,or robotic surgery?"(1).In the current climate of limited hospital sources and control of medical costs,the authors afford the interesting topic of the cost-effectiveness evaluation of the robot-assisted distal pancreatectomy(RDP)in comparison to the laparoscopic(LDP)and open approaches(ODP).To accomplish this purpose,they focused their attention on both the clinical and the economical outcomes of the three different techniques.

Erectile dysfunction （ED） and stress urinary incontinence （SUI） from urethral sphincteric deficiency is not an uncommon problem. The commonest etiology is intervention for localized prostate cancer and/or radical cystoprostatectomy for muscle invasive bladder cancer. Despite advances in surgical technology with robotic assisted laparoscopic prostatectomy and nerve sparing techniques, the rates of ED and SUI remain relatively unchanged. They both impact greatly on quality of life domains and have been associated with poor performance outcomes. Both the artificial urinary sphincter and penile prosthesis are gold standard treatments with proven efficacy, satisfaction and durability for end-stage SUI and ED respectively. Simultaneous prosthesis implantation for concurrent conditions has been well described, mostly in small retrospective series. The uptake of combination surgery has been slow due in part to technical demands of the surgery and to an extent, a heightened anxiety over potential complications. This paper aims to discuss the technical aspect of concurrent surgery for both disease entity and the current published outcomes of the various surgical techniques with this approach.
