“…The three parts of the E. ovulum gut (foregut, midgut and hindgut) are easily distinguishable and are similar to those seen in other Coleopterans (Sinha, 1958;Díaz et al, 1998Díaz et al, , 2000Díaz et al, , 2003Rubio et al, 2008;Bu and Chen, 2009;Aldigail et al, 2013;Sarwade and Bhawane, 2013;Singh and Prasad, 2013;Borges et al, 2015;Candan et al, 2019).…”

“…The foregut is responsible for the transport of food to the crop whose function is the temporary storage of food (Díaz et al, 2000;Rubio et al, 2008;Bu and Chen, 2009;Aldigail et al, 2013;Singh and Prasad, 2013;Sousa et al, 2013;Candan et al, 2019). Various authors have illustrated subtle differences among species (Sinha, 1958;Vazquez-Arista et al, 1997;Díaz et al, 1998Díaz et al, , 2000Díaz et al, , 2003Rubio et al, 2008;Bu and Chen, 2009;Aldigail et al, 2013;Sarwade and Bhawane, 2013;Singh and Prasad, 2013;Borges et al, 2015;Candan et al, 2019). The spines observed within the esophageal intima of E. ovulum were similar to those observed in A.diaperinus (Coleoptera: Tenebrionidae), Dendroctonus micans, D. ponderosae, D. pseudotsugae pseudotsugae, D. rufipennis and D. terebrans (Coleoptera: Scolytidae) (McAllister et al, 1995;Díaz et al, 2003).…”

“…In A. diaperinus (Coleoptera: Tenebrionidae), hindgut is divided into two distinct sections, the anterior small intestine and the posterior large intestine (McAllister et al, 1995). Borges et al (2015) pointed out that the hindgut in A. bipunctata is composed of the ileum, rectum and rectal canal. The main functions of the hindgut are the absorption of water, salts from the feces and urine (Smith, 1968).…”

The structural morphology of mouthparts, the distribution of sensilla on the mouthparts, histology, and the morphology of the alimentary canal in adult Eusomus ovulum Germar, 1824 were examined under both light and scanning electron microscopy (SEM). The mouthparts are located at the tip of the short rostrum. The mandibles, the maxillae and the labial palpi comprise the moveable mouthparts. Also there are sensillae which act as chemoreceptors on the terminal segment of the snout. Alimentary canal of adult E. ovulum is divided into three main regions, foregut, midgut and hindgut. The first part of the gut is foregut, which is made up of a pharynx, esophagus, crop and proventriculus. The pharynx extends from the mouth, having muscle attachments radiating out from its surface and connecting with the head region. The esophagus is a narrow epithelial tube contiguous and posterior to the pharynx. The proventriculus consists of 8 sclerotized plates. The midgut, which is anteriorly bulbous with a tubular posterior half. Gastric caeca were found on the posterior region of the midgut. The midgut is surrounded by outer muscles and inner columnar epithelium. The hindgut has pylorus, ileum, colon, and rectum. There are three histological layers of the hindgut from lumen to hemocoel: intima, epithelium, muscles. The hindgut has a cryptonephridial attachment for the six Malpighian tubes anterior to the rectum. The aim of the present study is to contribute information on the morphology of mouthparts, and the morphology and histology of the alimentary tract of the insect.

“…For this reason, PLC films deposition time was increased in 5 minutes and an extra PLA fiber layer was added to maintain the mechanical resistance and increase the thickness (4L35/40 condition). This thickness value of 0.63 mm is similar to RCA commercial patches [31]. SEM images of cross sections were taken for 4L35/40 condition (Fig 5C).…”

Development of a novel automatable fabrication method based on electrospinning co electrospraying for rotator cuff augmentation patches

et al. 2019

Rotator cuff tear is one of the most common shoulder diseases. Rotator cuff augmentation (RCA) is trying to solve the high retear failure percentage after the surgery procedures (20–90%). The ideal augmentation patch must provide a temporal mechanical support during the healing process. In this work, we proposed a simple method for the fabrication of synthetic RCA patches. This method combines the use of electrospraying to produce poly-L-lactic-co-ε-caprolactone (PLC) films in an organogel form and electrospinning to produce poly(lactic) acid (PLA) nanofibers. The device consists in a combination of layers, creating a multilayered construct, enabling the possibility of tuning its mechanical properties and thickness. Besides, both techniques are simple to escalate for industrial production. A complete characterization has been performed to optimize the involved number of layers and production time of PLC films and PLA nanofibers fabrication, obtaining a final optimal configuration for RCA devices. Structural, mechanical and suture properties were evaluated. Also, the possibility of surface functionalization to improve the bioactivity of the scaffold was studied, adding aligned electrospun PLA nanofibers on the surface of the device to mimic the natural tendon topography. Surface modification was characterized by culturing adult normal human dermal fibroblasts. Lack of toxicity was detected for material presented, and cell alignment shape orientation guided by aligned fibers, mimicking tendon structure, was obtained. Cell proliferation and protein production were also evaluated.

“…The alimentary canal, in insects, mainly divides into foregut, midgut and hindgut, and is the primary organ of digestive absorption, detoxification metabolism, immune defense and oxidative stress response (Hakim et al ., ; Azevedo et al ., ; Borges et al ., ). Generally, the midgut occupies the majority of the digestive tract and is also considered to be the center of physiological functions in most insects (Dow, ; Hakim et al ., ; Zhu et al ., ).…”

The physiological functions of insect foregut, especially in xenobiotic detoxification, are scarcely reported because of unimportance in appearance and insufficient molecular information. The cockroach Periplaneta americana, an entomological model organism, provides perfect material to study physiological functions of foregut tissue due to its architectural feature. Through Illumina sequencing of foregut tissue from P. americana individuals (control) or insects treated with cycloxaprid, as a novel neonicotinoid insecticide, 54 193 166 clean reads were obtained and further assembled into 53 853 unigenes with an average length of 366 bp. Furthermore, the number of unigenes involved in xenobiotic detoxification was analyzed, mainly including 70 cytochrome P450s, 12 glutathione S-transferases (GSTs), seven carboxylesterases (CarEs) and seven adenosine triphosphate-binding cassette (ABC) transporters. Compared to control, the expression of 22 xenobiotic detoxification unigenes was up-regulated after cycloxaprid application, mainly containing 18 P450s, one GST, two CarEs and one ABC adenosine triphosphate transporter, indicating that the oxidation-reduction was the major reactive process to cycloxaprid application. Through quantitative real-time polymerase chain reaction analysis, the expression of selected unigenes (six P450s, one GST and one CarE) was up-regulated at least two-fold following cycloxaprid treatment, and was generally in agreement with transcriptome data. Compared to the previous midgut transcriptome of P. americana, it looks like the expressive abundance of the xenobiotic detoxification unigenes might be important factors to the detoxifying functional differences between foregut and midgut. In conclusion, insect foregut would also play important roles in the physiological processes related to xenobiotic detoxification.
