Cryptorchidism is one of the most frequent causes of nonobstructive azoospermia(NOA)in *** it is well known that spermatogenesis is more impaired in bilateral than in unilateral cryptorchidism,previous studies have only described small cohorts or inhomogeneous ***,we analyzed a cohort of 225 men with only a history of cryptorchidism as sole etiopathogenetic factor for NOA,and compared testicular sperm extraction(TESE)outcomes between men with bilateral versus unilateral *** results show no difference in follicle-stimulating hormone(FSH)levels and testicular volumes between men with a history of bilateral cryptorchidism compared to unilateral cryptorchidism(median:21.3 IU I^-1 vs 19.3 IU I^-1,P=0.306;and 7.2 ml vs 7.9 ml,P=0.543,respectively).In addition,sperm retrieval rates were similar(66.2%vs 60.0%,P=0.353).Using multivariate analysis,we have found that only a low inhibin B level(above the assay's detection limit)was positively associated with successful sperm retrieval(P<0.05).Regarding intracytoplasmic sperm injection outcomes,we found that cumulative pregnancy rate and live birth rate per cycle were not statistically different between the two groups(17.4%vs 27.8%,P=0.070;and 16.1%vs 26.4%,P=0.067,respectively).Unexpectedly,there was no significant difference in hormonal profiles(FSH,luteinizing hormone[LH],testosterone,and inhibin B levels)and TESE outcomes between unilateral versus bilateral *** suggests that a history of unilateral cryptorchidism could reflect a bilateral testicular ***,inhibin B level might be a predictor of successful TESE.

Sliding motion has always been one of the major concerns when it comes to the analysis of viscoelastic contact problems.A new model simulating the transient sliding contact of smooth viscoelastic surfaces is developed in this *** taking the dry contact friction and the coupling between shear tractions and normal pressure into account,the effect of the early partial slip period,which is often neglected in the study of viscoelastic sliding contact problems,is investigated *** with solutions based on the frictionless assumption,the steady-state pressure profile is found to be slightly different under the effect of the partial slip regime,including a lower peak pressure and the shift of the contacting region in the direction opposite to the sliding ***,the time required for the viscoelastic contact to reach its steady state is delayed owing to the partial slip period preceding the global sliding motion.

Millions of dollars are being spent on gully rehabilitation to help reduce excess fine sediment delivery to the Great Barrier Reef(GBR).There is an urgent need for(i)prioritisation of active gullies for rehabilitation and(ii)the development of methodologies to inform the effectiveness of *** this study we analyse DEMs of Difference derived from 0.5 m resolution 2-3 year interval multi-temporal LiDAR data collected pre and post rehabilitation at three variable gully morphologies in the Burdekin *** analysis indicates that the highest annual average fine sediment erosion rates for the untreated control gullies occur at the linear gully(53.38 t ha^(-1)y^(-1))followed by linear-alluvial gully(34.24 t ha^(-1)y^(-1))and least at the alluvial gully(14.41 t ha^(-1)y^(-1)).The proportional loss or export of fine sediment from the gullies in their un-treated condition ranges from∼68 to 90%of what is eroded,and when the gullies are treated the proportion of fine sediment that is retained in the gully proportional to what is eroded increases to∼60%at all *** pre-treatment baseline erosion rates,and additional post treatment LiDAR captures,it is difficult to quantify the treatment *** results offer insights in the erosion mechanisms within different geomorphic gully morphologies and rehabilitation effects in these erosional *** study provides crucial knowledge of gully dynamics that can be coupled with other lines of evidence for better prioritisation of rehabilitation in the GBR catchments.
