The authors performed a comprehensive review of current literature to create a model comparing commonly evaluated variables in male factor infertility,for example,follicle-stimulating hormone(FSH),testicular volume(TV),and testosterone(T),to better predict sperm retrieval rate(SRR).Twenty-nine studies were included,9 with data on conventional testicular sperm extraction(cTESE)for a total of 1227 patients and 20 studies including data on microdissection testicular sperm extraction(mTESE)for a total of 4760 patients.A weighted-means value of SRR,FSH,T,and TV was created,and a weighted linear regression was then used to describe associations among SRR,type of procedure,FSH,T,and *** this study,weighted-means values demonstrated mTESE to be superior to cTESE with an SRR of 51.9%vs 40.1%.Multiple weighted linear regressions were created to describe associations among SRR,procedure type,FSH,T,and *** models showed that for every 1.19 mIU ml^(−1)increase in FSH,there would be a significant decrease in SRR by 1.0%.Seeking to create a more clinically relevant model,FSH values were then divided into normal,moderate elevation,and significant elevation categories(FSH20 mIU ml^(−1),respectively).For an index patient undergoing cTESE,the retrieval rates would be 57.1%,44.3%,and 31.2%for values normal,moderately elevated,and significantly elevated,*** conclusion,in a large meta-analysis,mTESE was shown to be more successful than cTESE for sperm *** has an inverse relationship to SRR in retrieval techniques and can alone be predictive of cTESE SRR.

The majority of patients with congenitally corrected transposition of the great arteries,also known as transposition of the great arteries{S,L,L}have ventricular septal defects(VSD),most commonly perimembranous VSD(pmVSD).Transcatheter device closure of pmVSD in these patients has not been widely *** present a case of device closure of pmVSD in L-TGA with an Amplatzer Duct Occluder II(ADOII)device using a deployment starting in the subpulmonary left *** case demonstrates some of the technical advantages of the ADOII device for VSD closure,specifically its low profile,symmetric shape,and soft *** characteristics are advantageous in closing conventional pmVSD but are especially useful in patients with challenging anatomic substrates.

Organic conjugated polymers and polymer dots as photocatalysts for hydrogen production

"Molecular evolution, phylogenetics, genomics, and other related topics are all critical to understanding evolutionary processes. All too frequently, however, they are treated separately in textbooks and courses, such that students fail to connect all of the concepts, principles, and nuances of the evolutionary processes. Integrated Molecular Evolution brings these related areas together in one vo

Calling underwater is a costly signal： size-related differences in the call rates of Antarctic leopard seals

Current Zoology 2017年第4期63卷 433-443页

作者： Tracey L. rogers Evolution & Ecology Research Centre School of BEES University of New South Wales Sydney Sydney NSW2052 Australia

It is proposed that where sexually selected vocal communication is an honest signal, the call production rate is predicted to change throughout the breeding season. Male leopard seals call underwater for many hours each day over their three- to four-month breeding season, and it is hypothesized that a decrease in calling rate would be associated with the declining body condition of smaller males. The calling rates of leopard seals were measured ( = 49 recordings) and compared between seals of different size classes throughout the breeding season. Male leopard seals produce their calls at more stable rates as they become larger. In this study, larger male leopard seals adopted a strategy of consistent underwater calling throughout the breeding season, whereas there was a breakdown in the calling stereotypy of the smaller males at its height. Toward the end of the breeding season, the smaller seals produced fewer calls in shortened calling bouts, and they took more rest periods. Therefore, underwater calling may represent an honest signal in the leopard seal. For marine mammals that call underwater, the production of repetitive sequences advertises the breath-holding ability of the caller to the listeners, and this ability may be related to male stamina and endurance, thus representing an honest signal that could be widespread in other species.
