There is an urgent need for novel drugs for treating cognitive deficits that are defining features of schizophrenia. The individual d- and l-enantiomers of the tetrahydroprotoberberine (THPB) d,l-govadine have been proposed for the treatment of cognitive deficiencies and positive symptoms of schizophrenia, respectively.
We examined the effects of d-, l-, or d,l-govadine on two distinct forms of cognitive flexibility perturbed in schizophrenia and compared them to those induced by a selective D1 receptor agonist and D2 receptor antagonist.
Male rats received d-, l-, or d,l-govadine (0.3, 0.5, and 1.0mg/kg), D1 agonist SKF81297(0.1, 0.3, and 1.0mg/kg), or D2 antagonist haloperidol (0.1-0.2mg/kg). Experiment 1 used a strategy set-shifting task (between-subjects). In experiment 2, well-trained rats were tested on a probabilistic reversal task (within-subjects).
d-Govadine improved set-shifting across all doses, whereas higher doses of l-govadine impaired set-shifting. SKF81297 reduced perseverative errorsgovadine as a treatment for cognitive deficiencies related to schizophrenia.
Current mastopexy techniques have evolved to decrease scar length and maintain a more consistent upper pole fullness, improving the breast shape. Many different approaches have tried to suspend breast tissues to achieve a more attractive upper pole. Most of the auto-augmentation mastopexy techniques use inferior-based breast parenchymal tissues to fill the upper part.
This paper presents a modified approach to fill the breast’s upper pole, with an inferolateral-based breast flap. The advantages of changing the inferior-based auto-augmentation technique to the inferolateral comprise improving blood supply and increasing repositioned breast flap’s mobility. In our technique, the breast tissue used to auto-augment the upper pole receives its blood supply from pectoral perforators and lateral breast tissue. When surgeons need more flap mobility, they can raise the medial edge of this flap from the pectoral fascia to mobilize this flap higher on the chest wall, depending on the lateral blood supply.

Graft use is inevitable in some primary and secondary rhinoplasty cases with cartilage or bone deficiency. Although rib graft is one of the best graft sources, it has several disadvantages. The purpose of this study is to minimize the risks of using rib grafts.
Between 2018 and 2020, a total of 21 patients aged between 25 and 55 have undergone revision rhinoplasty under general anesthesia with a split cartilage graft of central origin. A 3-4-mm-thick bridge was left at the superior and inferior edges of the donor area, and the graft was harvested from the central region without disrupting the costal integrity. A special retractor was placed between the perichondrium and the rib at the posterior of the costa to prevent damage to the pleura while cutting the rib. The previously marked grafts were cut in the donor area and harvested ready for use. The harvested grafts were used as spreader, strut, alar rim and nasal valve grafts.
None of the patients had complications due to rib graft harvesting. After the operation, pain in the donor region and analgesic requirement of these patients were less compared to the patients with full-layer grafts.
The grafts taken from the center of the costa without breaking its integrity seem quite suitable for revision rhinoplasty surgeries. This technique prevents various morbidities and enables patients to have a more comfortable postoperative period.

Several rhinoplasty and nasal reconstruction procedures require cartilage. Various studies have reported on the nasal septal cartilage as a donor site for Caucasian and Asian populations. However, studies regarding the Thai nasal septal cartilage dimensions are rare. This study aimed to examine the length, height, area, and thickness of the nasal septal cartilage, along with implications of the size and quantity of the available cartilage, for grafting in Thai cadavers.
We analyzed the nasal septal cartilage in 42 Thai cadavers. The length, height, area, and thickness were digitally measured using ImageJ 1.52 software, along with the size and area of the available cartilage for grafting after preserving a 10-mm L-strut. Data were compared between sexes.
The mean height, length, and area of the nasal septal cartilage were 30.96 ± 5.90 mm, 26.13 ± 6.90 mm, and 636.10 ± 196.13 mm
, respectively. The length did not differ significantly between sexes. However, the height and area in male cadavers were greate online Instructions to Authors http://www.springer.com/00266.
3D computer-simulated technology is becoming popular in China. Rhinoplasty with costal cartilage is a good option for Asians. However, the application of 3D imaging in Asian rhinoplasty with costal cartilage has not been systematically assessed.
To analyze the effect of 3D imaging in Asian rhinoplasty with costal cartilage.
In this study, 44 patients were included and randomly divided into 3D and non-3D imaging groups. We performed a prospective survey on the aesthetic scores for preoperative, simulated, and postoperative images and calculated the relative nasal index scores of patients in both groups. Additionally, surveys on satisfactions with surgical outcomes and doctor-patient communication in both groups were conducted.
The actual postoperative result was well consistent with the preoperative simulation result. The 3D computer simulation did not impact the satisfaction with surgical outcomes but increased that with doctor-patient communication. The 3D computer-simulated technology was an effective tool for doctor-patient communication and surgery planning in Asian rhinoplasty with costal cartilage.
