Under these optimal conditions 2-PE production by YF1702 was 5.09 g/L. This strain has the potential to increase the content of 2-PE in Baijiu production and enhance the aroma characteristics of Baijiu.[This corrects the article DOI 10.1097/GOX.0000000000002448.].The versatility of a pedicled groin flap can be further increased by raising it in a bilobed fashion. This allows the flap to cover both the volar and dorsal surfaces of a hand or forearm defect. A 48-year-old man sustained an avulsion amputation of his right forearm by a rolling machine in a workplace accident. Replantation of the right forearm was performed, and the postoperative course was uneventful. Unfortunately, the wound healing was complicated by circumferential marginal skin necrosis, which was confined to the distal forearm. A bilobed pedicled groin flap was performed for the wound coverage because reconstruction with a free flap would be very risky as the vessels were avulsed from the proximal part of the forearm. A good functional recovery of the hand and fingers was noted at 12 months' follow-up. The advantages of a bilobed pedicle groin flap are that it allows coverage of both the volar and dorsal surfaces at one setting and primary closure of the donor site is possible. Furthermore, a long tube-shaped pedicle in this flap can reduce the patient discomfort and prevent finger stiffness by allowing a range of motion exercise. In conclusion, the bilobed pedicled groin flap is a useful option to cover soft tissue defects involving both the volar and dorsal surfaces over the mid- to distal forearm, especially when the free flap is contraindicated.The evidence for lower limb flap (LLF) training regimens is equivocal. The commonest cause of LLF failure is venous congestion. The aim of this study was to investigate whether venous congestion could be reduced by patient-led isometric calf contractions during flap training. A prospective clinical study was conducted using photospectroscopy and laser Doppler (Oxygen to See) to assess healthy limbs and LLF characteristics during flap training and isometric calf contractions. Tissue oxygen saturation, venous congestion, and blood flow were measured at rest, as well as during and after limb dangling and calf contraction exercises. In the acute postoperative period following LLF surgery, dependency markedly reduced superficial flow (-55.20% ± 19.17%), with a concurrent increase in venous congestion (33.80% ± 28.80%); supine isometric contractions improved superficial flow and reduced venous congestion from postoperative day 5. Contractions cause a significant increase in blood flow in the outpatient cohort (+84.40% ± 7.86%, P = 0.009), with a mean time since discharge of 14 weeks. Our data suggest patient-led isometric calf exercises are well tolerated and may reduce venous congestion in the acute phase. Progressive changes toward normal physiological function were demonstrated in the outpatient rehabilitation period. Incorporating calf exercises into LLF rehabilitation may allow longer periods of leg dependency, quicker recovery from surgery, and ultimately improve outcomes.Genital arteriovenous malformations are rare and present unique surgical challenges in preserving urogenital function, abdominal wall integrity, and lower limb perfusion. A 32-year-old man with a giant abdominoscrotal arteriovenous malformation presented with recurrent heavy bleeding. Due to the high risk of rebleeding and fatal hemorrhage, surgery with curative intent was proposed and the patient was counseled on the risks of ischemia to the lower limb, testes, and penis. Preoperative embolization of the feeding vessels was performed. Three days later, surgical excision of the mass with the affected scrotum, left rectus muscle, sheath, and overlying abdominal skin followed. The testes were dissected from the malformation and preserved along with the right internal pudendal artery. The left thigh skin was advanced to the scrotal remnants and a neoscrotum created. find more The resulting large abdominal wall defect was reconstructed in layers with a pedicled anterolateral thigh flap, including innervated vastus lateralis muscle, to prevent herniation. Recovery was uneventful, and a 4-year follow-up revealed no significant clinical or radiological recurrence with recovery of flap sensation, retained erectile function, and no herniation. We report this case due to rarity of giant abdominoscrotal arteriovenous malformations and present preoperative embolization, surgical resection, and functional anterolateral thigh flap reconstruction as a valuable treatment option of this life-threatening illness.Hyaluronic acid (HA), both crosslinked and uncrosslinked, is used clinically to treat fine lines and provides additional improvements in skin quality attributes. The purpose of this study was to assess potential early differences in the expression of biological markers of skin quality in living human skin explants injected with uncrosslinked and crosslinked HA gels. Methods Living human skin explants injected with VYC-12L or noncrosslinked HA with mannitol (HYD) and noninjected controls were assessed via microscopy, histology, and immunohistochemistry on days 3 and/or 8 for biological markers of elasticity (collagen density, elastin, fibrillin-1) and hydration [aquaporin-3, acidic glycosaminoglycans (GAGs), HA]. Hydration was also assessed via a corneometer probe on days 0, 1, 2, and 8. Results On day 3 versus controls, VYC-12L moderately increased collagen density in the upper reticular dermis and clearly increased fibrillin-1 expression, with slight increases persisting on day 8. Increases with HYD were smaller and did not persist on day 8. Both VYC-12L and HYD increased aquaporin-3 expression and GAG content on days 3 and 8, but VYC-12L produced greater GAG increases in the reticular dermis. Day 8 instrument-assessed hydration increased by 49% and 22% for VYC-12L and HYD, respectively. Elastin expression in oxytalan and elaunin fibers was unchanged. Upper-dermal HA reductions suggested HA injection-induced hyaluronidase expression. Conclusion VYC-12L produced greater, more lasting improvements in biological markers of skin quality than HYD.
