Environmental pollution is currently identified as one of the major drivers of rapid decline of insect populations, and this finding has revitalized interest in insect responses to pollution. We tested the hypothesis that the pollution-induced decline of insect populations can be predicted from phenotypic stress responses expressed as morphological differences between populations inhabiting polluted and unpolluted sites. We explored populations of the brassy tortrix Eulia ministrana in subarctic forests along an environmental disturbance gradient created by long-lasting severe impacts of aerial emissions of the copper-nickel smelter in Monchegorsk, northwestern Russia. We used pheromone traps to measure the population densities of this leafrolling moth and to collect specimens for assessment of three morphological stress indices size, forewing melanization, and fluctuating asymmetry in wing venation. Wing length of E. ministrana increased by 10%, and neither forewing melanization nor fluctuating asymmetry changed from the unpolluted forest to the heavily polluted industrial barren. However, the population density of E. ministrana decreased 5 to 10 fold in the same pollution gradient. Thus, none of the studied potential morphological stress indicators signaled vulnerability of E. ministrana to environmental pollution and/or to pollution-induced environmental disturbance. We conclude that insect populations can decline without any visible signs of stress. The use of morphological proxies of insect fitness to predict the consequences of human impact on insect populations is therefore risky until causal relationships between these proxies and insect abundance are deciphered.
To compare the live birth rate and cost effectiveness of artificial cycle-prepared frozen embryo transfer (AC-FET) with or without GnRH agonist (GnRH-a) pretreatment for women with polycystic ovary syndrome (PCOS).

Open-label, randomised, controlled trial.

Reproductive centre of a university-affiliated hospital.

A total of 343 women with PCOS, aged 24-40years, scheduled for AC-FET and receiving no more than two blastocysts.

The pretreatment group (n=172) received GnRH-a pretreatment and the control group (n=171) did not. Analysis followed the intention-to-treat (ITT) principle.

The primary outcome measure was live birth rate. Secondary outcome measures included clinical pregnancy rate, implantation rate, early pregnancy loss rate and direct treatment costs per FET cycle.

Among the 343 women randomised, 330 (96.2%) underwent embryo transfer and 328 (95.6%) completed the protocols. Live birth rate according to ITT did not differ between the pretreatment and control groups [85/172 (49.4%) versus 92/171 (53.8%), absolute rate difference -4.4%, 95% CI -10.8% to 2.0% (P=0.45). Implantation rate, clinical pregnancy rate and early pregnancy loss rate also did not differ between groups, but median direct cost per FET cycle was significantly higher in the pretreatment group (7799.2 versus 4438.9 RMB, OR=1.9, 95%CI 1.2-3.4, P<0.001). Median direct cost per live birth was also significantly higher in the pretreatment group (15663.1 versus 8189.9 RMB, odds ratio [OR]=1.9, 95% CI 1.2-3.8, P<0.001).

Pretreatment with GnRH-a does not improve pregnancy outcomes for women with PCOS receiving AC-FET, but significantly increases patient cost.

For women with PCOS, artificial cycle-prepared FET with GnRH agonist pretreatment provides no pregnancy outcome benefit but incurs higher cost.

The aim of this study was to evaluate the genetic variations of ABCB5 in HCC patients with reference to healthy individuals and the clinicopathological significance. A pilot study has examined 20 out of 300 pairs HCC and paralleled blood samples using conventional sequencing method to cover all exons and exon/intron regions to investigate whether there will be novel variant sequence and mutation event. A total of 300 HCC and 300 healthy blood DNA samples were then examined by Sequenom MassARRAY genotyping and pyrosequencing for 38 SNP and 1 INDEL in ABCB5. Five novel SNPs were identified in ABCB5. Comparison of DNA from blood samples of HCC and healthy demonstrated that ABCB5 SNPs rs75494098, rs4721940 and rs10254317 were associated with HCC risk. KOS 953 Specific ABCB5 variants were associated with aggressive HCC features. SNP rs17143212 was significantly associated with ABCB5 expression level. Nonetheless, the paralleled blood and tumour DNA sequences from HCC patients indicated that ABCB5 mutation in tumours was not common and corroborated the TCGA data sets. In conclusion, ABCB5 genetic variants had significant association with HCC risk and aggressive tumour properties.
CYLD cutaneous syndrome (CCS; syn. Brooke-Spiegler syndrome) is a rare autosomal dominant hereditary disease characterized by multiple adnexal skin tumors including cylindromas, spiradenomas, and trichoepitheliomas. More than 100 germline mutations of the cylindromatosis (CYLD) gene have been reported in CCS and most of them are frameshift mutations or small alterations.

We identified a large, three-generation Chinese family with CCS, which consisted of 18 living family members, including six affected individuals. To explore the molecular biology of this family, we carried out targeted next-generation sequencing and Affymetrix CytoScan HD SNP array to analyze the mutation in the CYLD gene.

A novel large deletion mutation, NC_000016.9g.(50826498_50827517)_(50963389-50967346)del was found in the proband of this family. This deletion results in the loss of a nearly 140kb fragment of the CYLD gene, spanning exons 17~20, which represent the coding regions of the ubiquitin-specific protease domain. Further quantitative polymerase chain reaction proved that all patients and two proband-related family members carried this large deletion.

Our study expands the types of mutations in CCS and will undoubtedly provide valuable information for genetic counseling for families affected by the condition.
