A large fraction of the world grasslands and savannas are undergoing a rapid shift from herbaceous to woody-plant dominance. This land-cover change is expected to lead to a loss in livestock production (LP), but the impacts of woody-plant encroachment on this crucial ecosystem service have not been assessed. We evaluate how tree cover (TC) has affected LP at large spatial scales in rangelands o...

OBJECTIVE To compare characteristics for patients scheduled for autologous chondrocyte implantation with matrix-assisted chondrocyte implantation (MACI) with those enrolled in clinical trials and to describe differences in patient selection between countries. DESIGN Anonymized data from patients scheduled for MACI treatment in the knee in Europe and Australia/Asia were obtained from the Genzy...

Based on results from a survey study in a sample of Australian parents of twins, Raj and Morley (2007) reported that questions concerning the mode of conception of twins may be offensive to parents. We looked at the willingness to reply to questions about mode of conception of twin pregnancies in a large survey study that was completed by 20,150 mothers of twins from the Netherlands Twin Regist...

In this paper, Steam Assisted Gravity Drainage (SAGD) is introduced and its advantages over ordinary steam injection is demonstrated. A simple simulation model is built and three scenarios of natural production, ordinary steam injection, and SAGD are compared in terms of their cumulative oil production and cumulative oil steam ratio. The results show that SAGD can significantly enhance oil prod...

background: sacrococcygeal teratoma (sct) is a rare congenital tumor and its association with ivf pregnancy is not clear. there are limited reports of congenital tumors in ivf pregnancy. the exact embryogenesis of sct is not known but a genetic etiology has been reported. whether these congenital tumors have any association with assisted reproductive techniques remains obscure. case presentatio...

BACKGROUND Malignancies of the female reproductive tract are estimated to be the third most common group of cancers in women. OBJECTIVES We here aimed to present their epidemiological features in Golestan province located in Northeast of Iran. MATERIALS AND METHODS Data on primary female reproductive cancers diagnosed between 2004-2010 were obtained from Golestan Population-based Cancer Reg...

Oxidative stress (OS) has been recognized as a significant cause of suboptimal assisted reproductive outcome. Many of the sperm preparation and manipulation procedures that are necessary in the in vitro environment can result in excessive production of reactive oxygen species (ROS) thereby exposing the gametes and growing embryos to significant oxidative damage. Antioxidants have long been util...

Introduction Although embryo transfer provides a means of obtaining pregnancies from some mares that might not otherwise be capable of producing offspring, some mares cannot provide embryos for transfer. Mares in which embryo transfer may not be successful include those with: 1) failure of ovulation, 2) chronic endometritis (uterine inflammation), or 3) anatomical problems (e.g., cervical adhes...

BACKGROUND AND OBJECTIVES Since little is known regarding the correlation between different techniques used during hysteroscopic septoplasty and reproductives outcomes, we amied to evaluate the results of two different techniques of hysteroscopic septoplasty (HS). METHODS Data were retrospectively reviewed on 49 patients who underwent HS for symptomatic septate uterus from January 1, 2010, th...
