Figure 3 in Position and development of oocytes in velvet worms shed light on the evolution of the ovary in Onychophora and Arthropoda
Figure 3. Diagram of internal organization of the three major ovarian types in Onychophora: exogenous ovary (A, D), pseudoendogenous ovary (B, E), and endogenous ovary (C, F). A, cross-section of the exogenous ovary with separate ovarian tubes that occur, e.g. in Euperipatoides rowelli, Phallocephale tallagandensis, and Ooperipatellus insignis (Australian Peripatopsidae). B, cross-section of the pseudoendogenous ovary of Metaperipatus inae (Peripatopsidae, Chile). C, cross-section of the endogenous ovary of Epiperipatus biolleyi (Peripatidae, Costa Rica). Note the complete lack of a sterile epithelium. D, detail of the composition of the ovarian wall in Opisthopatus roseus (Peripatopsidae, South Africa). E, detail of the ovary in Met. inae. F, detail of the ovarian wall in Ep. biolleyi. Abbreviations: bl, basal lamina; ct, connective tissue; fc, flattened cell; ge, germinal epithelium; hc, haemocoel; lu, ovarian lumen; mc, muscle cell; oc, oocyte; se, sterile epithelium; st, stalk; tr, tracheae.
Figure 1 in Position and development of oocytes in velvet worms shed light on the evolution of the ovary in Onychophora and Arthropoda
Figure 1. Simplified diagrams of paired versus variously fused structure of the ovarian tubes in Onychophora. Tissues are represented in light grey, ovarian lumen in dark grey. A, exogenous ovary of Typhloperipatus williamsoni (South-East Asian Peripatidae). Modified and complemented according to descriptions given by Kemp (1914). B–D, exogenous ovaries in three species of Peripatopsidae. B, Euperipatoides rowelli (Australia). Note the completely separate ovarian tubes in the middle of the ovary and the fused ovarian lumens at the anterior and posterior ends. A similar ovarian organization has been described in Peripatoides novaezealandiae from New Zealand (Sheldon, 1890: fig. 26). C, Peripatopsis balfouri (South Africa, cf. Fig. 2A). Although the ovarian tubes are fused, their lumens are separate along their entire length. D, Opisthopatus roseus (South Africa). Note the unpaired ovarian structure with a single lumen. E, pseudoendogenous ovary of Metaperipatus inae (Peripatopsidae, Chile, cf. Fig. 2B) with fused ovarian tubes but separate lumens. F, endogenous ovary of Epiperipatus biolleyi (Neotropical Peripatidae, cf. Fig. 2C) with lumens communicating only at the posterior end. G, endogenous ovary of Mesoperipatus tholloni (Peripatidae, Tropical Africa), modified and complemented after Bouvier (1905). Each ovarian tube is completely separate in this species.
Figure 10 in Position and development of oocytes in velvet worms shed light on the evolution of the ovary in Onychophora and Arthropoda
Figure 10. Mapping of three major types of onychophoran ovaries on simplified trees representing three different hypotheses on the phylogenetic relationships of Onychophora. Onychophoran subgroups are designated by their geographical distribution. Note that the suggestion of the exogenous type as an ancestral feature of Onychophora is consistent with all three phylogenetic hypotheses. A, both Peripatopsidae and Peripatidae are monophyletic (phylogeny modified from Monge-Nájera, 1995: fig. 10). B, Peripatidae are nonmonophyletic (phylogeny simplified from Reid, 1996: fig. 29). C, Peripatopsidae are nonmonophyletic (phylogeny simplified from Reid, 1996: fig. 28).

Contrasting association of Leptin receptor polymorphisms and haplotypes with polycystic ovary syndrome in Bahraini and Tunisian women: a case–control study
<p><span><b>Background</b>. This study examined the contribution of ethnicity to the association of leptin receptor gene (<i>LEPR)</i> genetic variants with polycystic ovary syndrome (PCOS) in Tunisian and Bahraini Arabic-speaking women.<b> </b></span></p> <p><span><b>Methods. </b>Subjects consisted of 320 women with PCOS, and 446 eumenorrhic women from Tunisia, and 242 women with PCOS and 238 controls from Bahrain. Genotyping of (exonic) rs1137100 and rs1137101 and (intronic) rs2025804 <i>LEPR</i> variants was done by allelic exclusion.<b> </b></span></p> <p><span><b>Results. </b>The minor allele frequencies of rs1137100 and rs1137101 were significantly different between PCOS cases and control women from Bahrain but not Tunisia, and <i>LEPR</i> rs1137101 was associated with increased PCOS susceptibility only in Bahraini subjects. Furthermore, rs1137100 was associated with decreased PCOS risk among Bahrainis under codominant and recessive models; rs1137100 was negatively associated with PCOS in Tunisians after controlling for testosterone. In addition, rs2025804 was associated with increased PCOS risk among Tunisian but not Bahraini women, after adjusting for key covariates. Negative correlation was seen between rs1137101 and triglycerides in Tunisians, while HOMA-IR and insulin correlated with rs2025804 and rs1137101 among Bahraini subjects, and rs1137101 correlated with estradiol and prolactin. Taking TAG haplotype as common, positive association of TAA and negative association of TGG haplotype with PCOS was seen among Bahraini women; no three-locus PCOS-associated haplotypes were found in Tunisians.<b> </b></span></p> <p><span><b>Conclusions. </b>T<span>his study is the first to demonstrate the contribution of ethnicity to the association of <i>LEPR</i> gene variants with PCOS</span>, thereby highlighting the significance of controlling for ethnicity in gene association investigations.</span></p>
Data from: Ovary development and cold tolerance of the invasive pest Drosophila suzukii (Matsumura) in the central plains of Kansas, United States
Environmental challenges presented by temperature variation can be overcome through phenotypic plasticity in small invasive ectotherms. We tested the effect of thermal exposure to 21, 18, and 11°C throughout the whole life cycle of individuals, thermal exposure of adults reared at 25°C to 15 and 11°C for a 21-d period, and long (14:10 hr) and short (10:14 hr) photoperiod on ovary size and development in Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) cultured from a recently established population in Topeka, Kansas (United States). Examination of the response to temperature and photoperiod variation in this central plains population provides insight into the role of phenotypic plasticity in a climate that is warmer than regions in North America where D. suzukii was initially established. We found both low temperature and short photoperiod resulted in reduced ovary size and level of development. In particular, reduced ovary development was observed following exposure to 15°C, indicating that ovary development in females from the central plains population is more sensitive to lower temperature compared with populations examined from the northern United States and southern Canada. We also provide evidence that D. suzukii reared at 25°C are capable of short-term hardening when exposed to −6°C following 4°C acclimation, contrary to previous reports indicating flies reared at warm temperatures do not rapidly-cold harden. Our study highlights the central role of phenotypic plasticity in response to winter-like laboratory conditions and provides an important geographic comparison to previously published assessments of ovary development and short-term hardening survival response for D. suzukii collected in cooler climates.
Data from: Electroacupuncture mimics exercise-induced changes in skeletal muscle gene expression in women with polycystic ovary syndrome
<p class="1stparatext">Context: Autonomic nervous system activation mediates the increase in whole-body glucose uptake in response to electroacupuncture but the mechanisms are largely unknown.</p> <p class="1stparatext">Objective: To identify the molecular mechanisms underlying electroacupuncture-induced glucose uptake in skeletal muscle in insulin-resistant overweight/obese women with and without polycystic ovary syndrome (PCOS).</p> <p class="1stparatext">Design/Participants: In a case-control study, skeletal muscle biopsies were collected from 15 women with PCOS and 14 controls before and after electroacupuncture. Gene expression and methylation was analyzed using Illumina BeadChips arrays.</p> <p class="1stparatext">Results: A single bout of electroacupuncture restores metabolic and transcriptional alterations and induces epigenetic changes in skeletal muscle. Transcriptomic analysis revealed 180 unique genes (<i>q </i>< 0.05) whose expression was changed by electroacupuncture, with 95% of the changes towards a healthier phenotype. We identified DNA methylation changes at 304 unique sites (<i>q </i>< 0.20), and these changes correlated with altered expression of 101 genes (<i>p</i> < 0.05). Among the 50 most upregulated genes in response to electroacupuncture, 38% were also upregulated in response to<b> </b>exercise. We identified a subset of genes that were selectively altered by electroacupuncture in women with PCOS. For example, <i>MSX1 </i>and <i>SRNX1 </i>were decreased in muscle tissue of women with PCOS and were increased by electroacupuncture and exercise. siRNA-mediated silencing of these two genes in cultured myotubes decreased glycogen synthesis, supporting a role for these genes in glucose homeostasis.</p> <p class="1stparatext">Conclusion: Our findings provide evidence that electroacupuncture normalizes gene expression in skeletal muscle in a manner similar to acute exercise. Electroacupuncture might therefore be a useful way of assisting those who have difficulties performing exercise.</p>
