Scleral Defect Repair in Rabbits

Check if the same lab product or an alternative is used in the 5 most similar protocols
A deep sclerectomy was performed on the left eye of 16 rabbits under an operating microscope. Briefly, the dorsal bulbar conjunctiva was incised through the conjunctival sac to expose the sclera. A 4 × 4mm square scleral incision was made 3 mm posterior to the limbus. Dissection was continued until reaching the choroid. The defect thus created was filled either by a 4 × 4 mm square of lhUC-AM with epithelial side facing up (n = 12) or by replacing the freshly excised sclera (n = 4). Grafts were sutured using 8 to 10 separated stitches of 9/0 PGA filament (Vicryl®, Ethicon, Johnson and Johnson, Issy les Moulineaux, France). Bulbar conjunctival incision was then closed with continuous suture, using 6-0 PGA polyfilament (Vicryl®, Ethicon, Johnson and Johnson, Issy les Moulineaux, France).

Check if the same lab product or an alternative is used in the 5 most similar protocols
An open castration technique was used for castration of the boars and the scrotal incision was closed to reduce interference by fellow animals in the post-operative period. Following preparation of the skin for aseptic surgery, the non-dependent testis was digitally immobilised in the scrotum. A single longitudinal incision, parallel to the median raphe, was made through the scrotal skin, subcutaneous tissue and tunica vaginalis. The testis, epididymis and part of the spermatic cord were identified and isolated. The spermatic cord and vessels were ligated. The spermatic cord was incised and the testis, epididymis and distal part of the spermatic cord were removed. The tunica vaginalis was closed with a continuous suture pattern with absorbable suture material (Vicryl, Ethicon, Inc., Johnson & Johnson Medical Pty. Ltd., North Ryde, Australia). The scrotal skin was closed with a continuous intradermal suture pattern using absorbable suture material (Vicryl, Ethicon, Inc., Johnson & Johnson Medical Pty. Ltd., North Ryde, Australia).

Check if the same lab product or an alternative is used in the 5 most similar protocols
To model focal neuropathic pain, the saphenous nerve of the right hindlimb was ligated ten days prior to imaging14 (link). Mice were anesthetized with isoflurane (5% induction, 2% maintenance in 1 L/min O2) and administered buprenorphine (SC, 0.05 ml, 0.3 mg/ml) for analgesia. Body temperature was maintained at 37 °C with a thermometer feedback controlled heatpad. The anterior aspect of the left hindlimb was shaved and disinfected with betadine and alcohol (3x alternating), and an 8 mm incision was made overlying the saphenous triad. Subcutaneous and connective tissue was blunt dissected to isolate the saphenous nerve and 8-0 braided suture (Vicryl, Ethicon Inc., USA) was tied loosely around the nerve at 1 mm intervals. Sham animals underwent the same incision and dissection surgical procedure but no ligation was performed. Subsequent to ligation, the primary incision was closed (5-0 Vicryl, Ethicon Inc., USA) and mice were recovered and returned to their homecage.

Modified W-shaped Tongue Reduction Surgery

Check if the same lab product or an alternative is used in the 5 most similar protocols
The technique used for all procedures was a modified W-shaped pattern with keyhole. The surgeon marked the W-shaped pattern with keyhole with a marking pen (Fig. 1, above, third from left) followed by injection of local anesthesia containing epinephrine into the tongue. We use the “modified W excision with keyhole” to tailor the reduction of tongue bulk, both length and width, to fit within the borders of the lingual surface of the mandible while placing the neurovascular bundles, which course from ventrolaterally to dorsomedially, at low risk.
Bovie electrocautery on “cut” mode is used to cut all mucocutaneous incisions, including the keyhole. Then, Bovie electrocautery on “coagula-tion” mode is used to resect the muscularis. Next, hemostasis is checked and obtained with Bovie electrocautery. Layered closure of the tongue is performed with interrupted 4–0 Vicryl (Ethicon, Inc., Somerville, N.J.) sutures followed by a running 4–0 Vicryl suture to oversew each suture line. The average duration of tongue reduction surgery was determined for patients who had individual surgical times recorded (n = 33).

Bilateral Ovarian and Uterine Horn Resection in Rats

Check if the same lab product or an alternative is used in the 5 most similar protocols
Xylazine (Alfazyne, Alfasan, Amsterdam) was given at 10 mg/kg/i.m. for neuromuscular blockage and ketamine (Ketalar Flakon, Pfizer, Istanbul) was given at 50 mg/kg/i.m. for anesthesia in all surgeries. Next, the rat was placed in a supine position. The abdomen was shaved, and the skin was cleaned. A midline laparotomy was performed with a 2–3 cm vertical incision. After the surgical procedures, the abdomen was closed by suturing in layers.
All surgeries were performed by same surgeons (MCS, OLT, RTA, SKA);

In the first surgery, bilateral ovarian tissues were ligated with a 3.0 polyglactin 910 suture (Vicryl, Ethicon, USA) from the proximal and distal zones and resected.

In the second surgery, the left uterine horns of all rats (in all groups) were resected by ligation with a 3.0 polyglactin 910 suture (Vicryl, Ethicon, USA) from the proximal zone.

In the third surgery, the right uterine horns of all rats (in all groups) were resected by using the same procedure as that used in the previous surgery. The animals were sacrificed by decapitation.

Laparoscopic Myomectomy Technique Comparison

Check if the same lab product or an alternative is used in the 5 most similar protocols
All operations were performed by the same surgeon (BM). The first entry into the abdomen was made by direct trocar entry from the umbilicus or Lee Huang point according to the size of the fibroid, and a 10-mm laparoscope was placed in this port. The 30-degree optic was used in all cases to provide a wide viewing angle. Then, 5-mm accessory trocars were placed in the right and left lower quadrant and suprapubic area. Rumi II was used as the uterine manipulator. A Harmonic scalpel (Ethicon Endo-Surgery, Cincinnati, OH, USA) was used to create the incision in the uterine serosa. A Vicryl (Ethicon, Somerville, NJ, USA) 0 USP 40-mm ½ taper needle suture was used for the Vicryl group patients. A V-Loc 180 (Covidien, Mansfield, MA, USA) 0 USP 37-mm ½ taper needle suture was used for the barbed suture group patients. One, two, or three layers were closed continuously depending on the depth of the fibroid inside the myometrium. All fibroids were morcellated with a Rotocut G1 electronic morcellator device (Karl Storz, Tuttlingen, Germany) and then removed from the abdomen.
Hemoglobin was measured the day before the operation and at the eighth postoperative hour. A cut-off value of <7 g/dL was determined for blood transfusion. Transfusion was performed in symptomatic patients with higher values.

Tracheal Resection and Anastomosis Technique

Check if the same lab product or an alternative is used in the 5 most similar protocols
The surgical principles of tracheal resection and anastomosis (TR/A) have been already described (8 (link)). In our experience, after the two 2/0 polyglactin (Vicryl; Ethicon, Inc., Somerville, NJ, USA) traction sutures were placed in the lower tracheal tract and to the larynx, respectively, the posterior anastomosis was carried out first through a 4/0 polydioxanone (PDS; Ethicon, Inc., Somerville, NJ, USA) continuous suture on the membranous pars; soon after, the latero-anterior cartilaginous pars was sutured with interrupted 3/0 Vicryl stitches. The traction sutures were then tied together to release tensions on the anastomosis and pretracheal muscle flaps are used to cover the anastomosis.

Sciatic Nerve Compression Injury Model

Check if the same lab product or an alternative is used in the 5 most similar protocols
All surgical procedures were performed under general anesthesia with 3% isoflurane. Routinely, Buprenorphine (Temgesic ® , 0.3 mg/ml, 0.05 mg/kg; Indivior AG, Baar, Switzerland) was administered before and after the surgery. The left sciatic nerve was approached dorsally using a gentle spreading technique of the gluteus muscle. The sciatic nerve was compressed with a titanium hemostatic clip (Vitalitec small clip; Péters surgical, Bobigny, France) at 10 mm proximally from the sciatic bifurcation point into tibial and peroneal branches. For this, a custom-made instrument that was preset to leave only the maximum lumen size of 250 μm after complete compression was used [Citation22]. The compressing clip was left undisturbed on the sciatic nerve until the end of the experimentation. Muscles and fascia layers were closed with a single resorbable stitch (5/0 Vicryl, Ethicon) and the skin was closed by a continuous running suture (5/0 Vicryl, Ethicon). For analgesia, the animals received subcutaneous injections of Meloxicam (Metacam ® , 2 mg/ml; Boehringer Ingelheim GmbH, Basel, Switzerland) 2 mg/kg bodyweight postoperatively, and then 1 mg/kg bodyweight every 24 h for 2 days. Furthermore, Paracetamol (Becetamol ® , 100 mg/ml; Gebro Pharma AG, Liestal, Switzerland) 50 mg/kg bodyweight/day was added to the drinking water for 7 days.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
