Fig. 10 in Comparative anatomy of venom glands suggests a role of maternal secretions in gall induction by cynipid wasps (Hymenoptera: Cynipidae)
Fig. 10. Transmission electron micrographs of the venom gland secretory region of Cynipoids. (A, A′) Disholcaspis quercusmamma agamic generation. (B, B′) Acraspis erinacei agamic generation. (C, C′) Amphibolips confluenta sexual generation. (D, D′, D") Diastrophus nebulosus. (E, E′) Antistrophus laciniatus. (F) Synergus sp. (G) Schematic summarizing the organization of the venom secretory unit inferred from TEM images. The extracellular medium of the 3 tested Cynipini contain high concentrations of nanometric particles. In D. quercusmamma, these particles (P1) are also found in secretory vesicles and seem to assemble into fibers once secreted. In A. erinacei, some secretory vesicles are observed, without particle content, whereas no vesicle are clearly visible in A. confluenta. In this last species, secretory units are surrounded by large granules. In Diastrophus nebulosus, nanometric particles seems to assemble into a 250 nm particle (P2) within secretory vesicles. Once secreted these P2 seem to form larger agglomerations. Lamellar bodies are also secreted in this species. The secretory unit is reduced and surrounded by light vesicles that do not contain any particles in the inquiline Synergus sp. An accumulation of vesicles and granules is observed around the secretory unit of A. laciniatus. In comparison, virus-like particles are secreted in Leptopilina sp. (adapted from Ferrarese et al., 2009). Legend: d: duct, e: extracellular medium, v: vesicle, mv: microvilli, g: granules, P1: 50 nm particle, P2: 250 nm particle, L: lamellar body, VLP: viruslike particle, p40: virus-like particle protein p40.

Fig. 1 in Comparative anatomy of venom glands suggests a role of maternal secretions in gall induction by cynipid wasps (Hymenoptera: Cynipidae)
Fig. 1. Diversity of galls induced by Cynipid wasps. Four clades of Cynipidae contain gall-inducing species: the rose-gallers (Diplolepidini), the herb gallers (Aylacini sensu lato), the non-rose Rosaceae gallers (Diastrophini), and the oak gallers (Cynipidini). Cynipidini alternate two generations, sexual and agamic, that differ in their phenotype. Cynipid galls can be induced in various organs (bud, flower, fruit, leaf, root, or stem), and contain one larval chamber (unilocular gall) or several (multilocular gall).

Clinical and histopathological features of 81 cases of canine apocrine gland carcinoma of the anal sac
<p>Canine apocrine gland anal sac adenocarcinoma (AGASAC) is a malignant tumour with variable clinical progression. The objective of this study was to use robust multivariate models, based on models employed in human medical oncology, to establish clinical and histopathological risk factors of poor survival. Clinical data and imaging of 81 cases with AGASAC were reviewed. Tissue was available for histological review and immunohistochemistry in 49 cases. Tumour and lymph node size were determined using the response evaluation criteria in solid tumours system (RECIST). Modelling revealed tumour size over 2 cm, lymph node size grouped in three tiers by the two thresholds 1.6 cm and 5 cm, surgical management, and radiotherapy were independent clinical variables associated with survival, irrespective of tumour stage. Tumour size over 1.3 cm and presence of distant metastasis were independent clinical variables associated with first progression free interval. The presence of the histopathological variables of tumour necrosis, a solid histological pattern, and vascular invasion in the primary tumour were independent risk factors of poor survival. Based upon these independent risk factors, scoring algorithms to predict survival in AGASAC patients are presented.</p>
Diet nutritional condition affects tergal gland secretion and courtship success of male cockroaches
<p>An integral part of the courtship sequence of the German cockroach (<em>Blattella germanica</em>) involves the male raising his wings to expose tergal glands on his dorsum. When a female cockroach feeds on the secretion of these glands, she is optimally positioned for mating. Core chemical components have been identified, but the effect of male diet on the tergal gland secretion remains unexplored. After validating the pivotal role of tergal feeding in mating, we starved or fed reproductively mature males for one week. We then paired each male with a sexually receptive female and observed their interactions through an infrared-sensitive camera. While starvation had no effect on male courtship behavior, it did influence the duration of female tergal feeding and mating outcomes. Females fed longer on the gland secretion of fed males, and fed males experienced greater mating success than starved males (73.9% vs. 48.3%, respectively). These results suggest that the quality of the tergal gland secretions, and by association mating success, are dependent on the nutritional condition of the male.</p>
Cell Atlas at Single-Nuclei Resolution of the Adult Human Adrenal Gland and Adrenocortical Adenomas
<p><strong>Abstract</strong></p> <p>The human adrenal glands are highly dynamic endocrine organs that are involved in the secretion of various hormones such as steroids and catecholamines. Here we present a single-nuclei and spatial transcriptomic analysis of healthy adult human adrenal glands to provide a complete adrenal gland atlas. With this, we show how such an atlas can be taken advantage when studying adrenocortical diseases, such as adrenocortical adenomas (ACA). Using nornal adrenal as reference, we showed a high intra-tumoural heterogeneity in the single-nuclei transcriptome of ACA, revealing the presence of specific cell populations associated with cortisol secretion and genetic background.</p> <p> </p> <p><strong>Data content</strong></p> <p>This dataset contains the two Visium replicates (NAG-7A and NAG-7B) processed using Space Ranger (spaceranger-1.0.0).</p> <p> </p>

The salivary gland transcriptome of Varroa destructor reveals suitable targets for RNAi-based mite control
<p><span>The mite <em>Varroa destructor</em> has a dramatic impact on beekeeping, and is one of the main causes of honey bee colony losses. This ectoparasite feeds on honey bees’ liquid tissues through a wound created on the host integument, which determines weight loss, a reduced lifespan and the transmission of viral pathogens. However, despite its importance, the mite feeding strategy and the host regulation role by the salivary secretions have been poorly explored. Here we contribute to fill this gap by identifying the salivary components of <em>V. destructor </em>and by studying their on mite feeding and survival. Our differential expression analysis identified 30 salivary gland genes encoding putatively secreted proteins, among which only 15 were found to be functionally annotated. These latter include proteins with putative antibacterial, antifungal, cytolytic, digestive and immunosuppressive function. To study the role of the identified genes on mite feeding we selected the three most highly transcribed genes coding for: a chitin-binding domain protein (CHIBIN), a Kazal domain serine protease inhibitor (KAZAL) and a papain-like cysteine protease (PAPA). Knockdown of CHIBIN was associated with a significant decrease of mite survival, likely interfering with the immune reaction to facilitate mite feeding. This work expands our knowledge of the host regulation and nutritional exploitation strategies adopted by ectoparasites of arthropods and allows the identification of novel targets for RNAi-based strategies <span> </span>of <em>Varroa </em>mite control. <span> </span></span></p>
