Fulltext Harvesting the maximum length of sciatic nerve from adult mice: a step-by-step approach

Bala U, Tan KL, Ling KH, Cheah PS

BMC Res Notes, 2014;7:714.
PMID: 25304607 DOI: 10.1186/1756-0500-7-714

Over the past several decades, many studies concerning peripheral nerve damage or regeneration have been performed. Mice have been widely used for many of these studies, with the sciatic nerve being the most targeted and preferred nerve. Therefore, techniques for harvesting mouse sciatic nerves of a maximum length that is sufficient for different analyses will be highly valuable. Here we describe a simple step-by-step guide for harvesting the maximum length of mouse sciatic nerve and compare the length of the harvested nerves gathered with the proposed method with nerves obtained using a conventional mid-thigh incision approach.

Effect of semen collection methods on the quality of pre- and post-thawed Bali cattle (Bos javanicus) spermatozoa

Sarsaifi K, Rosnina Y, Ariff MO, Wahid H, Hani H, Yimer N, et al.

Reprod. Domest. Anim., 2013 Dec;48(6):1006-12.
PMID: 23808560 DOI: 10.1111/rda.12206

This study was conducted to evaluate the response of Bali bulls (Bos javanicus) to different semen collection methods and their effects on fresh and post-thawed semen quality. The collection methods employed were electro-ejaculation (EE), transrectal massage (RM) and RM followed by EE (RM + EE). A total of 25 untrained Bali bulls (age between 2 and 4 years old) were subjected to the different semen collection methods. Fresh semen samples from all the 25 bulls were evaluated for volume, pH, general motility, live/dead ratio and abnormality using the conventional method. For fresh and frozen samples collected by EE and RM from 10 bulls, computer-assisted semen analysis system was used for precise quantitative measurement of motility, velocity and forward progression. Accucell photometer was used to measure sperm concentration in all samples, regardless fresh and frozen. Semen samples were obtained 100% of the attempts using EE, 84% using RM and 96% using RM + EE. There were no differences among the collection methods for fresh semen quality characteristics, including motility, morphology and viability, but pH and volume were higher for EE than RM and RM + EE. Higher sperm concentration was observed in semen collected by RM than the other two methods. Different age groups (2-3 and >3-4 years old) of the bulls did not show significant differences in volume, pH, sperm concentration, percentages in motility, live/dead ratio and normal sperm morphology. The quality of semen for general and progressive motility, VAP, VSL and VCL and acrosomal integrity after thawing was higher for RM than EE. In conclusion, Bali bulls appeared to respond best to EE and the combination of RM + EE than RM, as a method of semen collection, with a shorter time of stimulation required. Differences in age of the Bali bulls did not affect the semen quality.

Buccal Fat Pad: An Effective Option for Facial Reconstruction and Aesthetic Augmentation

Kim JT, Sasidaran R

Aesthetic Plast Surg, 2017 Dec;41(6):1362-1374.
PMID: 28849246 DOI: 10.1007/s00266-017-0962-4

INTRODUCTION: Autogenous grafting with lipoaspirate and dermo-fat grafting are popular techniques employed by plastic surgeons for correcting small volume facial defects and contour deformities. These techniques however present certain disadvantages. In this article, we present the use of the buccal fat pad graft as an alternative method of correcting such facial deformities.
PATIENTS AND METHODS: Free buccal fat pad grafting was carried out in 15 patients in our institution. All were harvested using an intraoral approach. The buccal fat pad graft was used to correct periorbital contour depressions, nasal tip deformities, as a camouflage graft over exposed silicon nasal implants and as a filler in the depression deformity after mass excision.
RESULTS: All 15 patients demonstrated good contour deformity correction without a significant graft resorption up to 3 years of follow-up. There were no donor site complications. The amount used ranged from 1 to 5 cc in volume as a spacer or barrier for the moderate-sized volume defect or depression, even though more than 5 cc of fat graft could be harvested if required.
CONCLUSION: In conclusion, the buccal fat pad graft represents an easy, expedient and exceptional tool for the correction of contour deformities, volume replacement or for aesthetic augmentation.

Conventional versus Minimally Invasive Vein Harvesting: A Clinical Audit of Wound Dehiscence Complications

Shiang SW, Vendargon SJ, Hamid SRBGS

J Coll Physicians Surg Pak, 2019 Apr;29(4):371-374.
PMID: 30925964 DOI: 10.29271/jcpsp.2019.04.371

OBJECTIVE: To determine the wound complications post coronary artery bypass graft surgery (CABG) by conventional vein harvest technique (CVH) and minimally invasive vein harvest technique (MIVH) in Hospital Sultanah Aminah Johor Bahru, Malaysia.
STUDY DESIGN: Clinical audit report.
PLACE AND DURATION OF STUDY: Hospital Sultanah Aminah Johor Bahru, Malaysia, from March 2016 to May 2017.
METHODOLOGY: Data were collected retrospectively from all 127 patients who underwent CABG with saphenous vein grafts, either with CVH technique (n=68), or MIVH technique (n=59) performed with Vasoview system. The rate of wound dehiscence was evaluated. Patients with severe wound dehiscence that required readmission and surgical intervention were identified for further evaluation.
RESULTS: There was total 26.8% of wound dehiscence in our study, which was not appreciably different between two groups (p=0.092). Patient with severe wound breakdown that required surgical intervention was significantly less in MIVH group (1/59, 1.7%) compared to CVH group (8/68, 11.8%, p=0.037). There was no significant difference in readmission rate between MIVH and CVH group (p=0.574).
CONCLUSION: There is significant reduction in severity of wound dehiscence post-saphenous vein harvesting among CABG patients with MIVH technique. However, there is no statistical difference in wound dehiscence and readmission rate between MIVH and CVH technique.
