Post-iboga alkaloids are secondary metabolites that are biosynthetically derived from iboga-type alkaloids via rearrangements of the indole and/or isoquinuclidine moieties. Herein, we categorize post-iboga alkaloids into five types based on the biosynthetic mode of transformation of the iboga scaffold. We then describe reported syntheses of post-iboga alkaloids, including our laboratory’s recent contributions, based on our own categorization.1 Introduction1.1 Iboga and Post-Iboga Alkaloids1.2 Classification of Post-Iboga Alkaloids1.2.1 Introduction to Type I Post-Iboga Alkaloids1.2.2 Introduction to Type II Post-Iboga Alkaloids1.2.3 Introduction to Type III Post-Iboga Alkaloids1.2.4 Introduction to Type IV Post-Iboga Alkaloids1.2.5 Introduction to Type V Post-Iboga Alkaloids2 Syntheses of Post-Iboga Alkaloids2.1 Syntheses of Type I Post-Iboga Alkaloids2.1.1 Syntheses of Monomeric Type I Post-Iboga Alkaloids2.1.2 Syntheses of Dimeric Type I Post-Iboga Alkaloids2.2 Syntheses of Type II Post-Iboga Alkaloids2.3 Synthetic Studies Toward Type III Post-Iboga Alkaloids2.4 Syntheses of Type IV Post-Iboga Alkaloids2.5 Synthesis of Type V Post-Iboga Alkaloids3 Conclusion and Outlook

Abstract Objection: To investigate the clinical value and significance of preoperative three-dimensional computerized tomography angiography (CTA) in laparoscopic radical gastrectomy for gastric cancer.Methods: The clinical data were analyzed retrospectively from 214 gastric cancer patients. We grouped according to whether to perform CTA. The gastric peripheral artery was classified according to CTA images of patients in the CTA group, and we compared and analyzed the difference of the data between the two groups.Results: The celiac trunk was classified according to Adachi classification: Type I (118/125, 94.4%),Type II (3/125, 2.4%),Type III (0/125, 0%),Type IV (1/125, 0.8%),Type V (2/125, 1.6%),Type VI (1/125, 0.8%).Hepatic artery classification was performed according to Hiatt classification standard:Type I (102/125, 81.6%),Type II (9/125, 7.2%),Type III (6/125, 4.8%),Type IV (2/125, 1.6%),Type V (3/125, 2.4%),Type VI (0, 0%),Others (3/125, 2.4%).And this study combined vascular anatomy and clinical surgical risk to establish a new splenic artery classification model. It was found that the operation time and estimated blood loss in the CTA group were significantly lower than those in the non-CTA group. In addition, the blood loss in the CTA group combined with ICG (Indocyanine Green) labeled fluorescence laparoscopy was significantly less than that in the group without ICG labeled. Conclusion: Preoperative CTA can objectively evaluate the vascular course and variation of patients, and then avoid the risk of operation, especially in combination with ICG labeled fluorescence laparoscopy, can further improve the quality of operation.

Objective: to determine the mean distance of the main trunk of the facial nerve from two commonly employed surgical landmarks (tragal pointer and tympanomastoid suture line) among a sample of Filipino adults undergoing parotidectomy.   Methods Study Design:            Prospective Descriptive Study Setting:                       Tertiary Government Training Hospital Subjects:                    22 patients without facial paralysis undergoing surgery for parotid neoplasms were evaluated intraoperatively.   Results: The main trunk of the facial nerve was found to be 9.0mm (standard deviation of 2.8mm) from the tragal pointer and 6.1mm (standard deviation of 2.0mm) from the tympanomastoid suture line.   Conclusion:  The mean distance from the main trunk of the facial nerve to two of the most commonly utilized landmarks in identification of the nerve during parotidectomy was 9.0mm (standard deviation of 2.8mm) from the tragal pointer and 6.1mm (standard deviation of 2.0mm) from the tympanomastoid suture line. These may serve as reference values for surgeons in safer identification and preservation of the facial nerve during parotidectomy.   Keywords: facial nerve, parotidectomy, tragal pointer, tympanomastoid suture line, anatomic landmarks

A growing, but poorly defined subset of patients with chronic limb-threatening ischemia (CLTI) have “no option” for revascularization. One notable subgroup includes patients with severe ischemia and advanced pedal artery occlusive disease, termed “desert foot,” who are at high risk for major amputation due to a lack of conventional revascularization options. Although new therapies are being developed for no-option patients with desert foot anatomy, this subgroup and the broader group of no-option patients are not well defined, limiting the ability to evaluate outcomes. Based on a systematic review, a classification of the no-option CLTI patient was constructed for use in clinical practice and studies. Several no-option conditions were identified, including type I—severe and pedal occlusive disease (desert foot anatomy) for which there is no accepted method of repair; type II—lack of suitable venous conduit for bypass in the setting of an acceptable target for bypass; type III—extensive tissue loss with exposure of vital structures that renders salvage impossible; type IV—advanced medical comorbidities for which available revascularization options would pose a prohibitive risk; and type V—presence of a nonfunctional limb. While type I and type II patients may have no option for revascularization, type III and type V patients have wounds, infection, comorbidities, or functional status that may leave them with few options for revascularization. As treatment strategies continue to evolve and novel methods of revascularization are developed, the ability to identify no-option patients in a standardized fashion will aid in treatment selection and assessment of outcomes.

There is debate regarding the most common fracture type at the base of the proximal phalanx of the fingers in children prior to closure of the epiphysis. In total, 100 consecutive children presenting with 103 fractures were included in a prospective study and their X-rays were reviewed by a consultant musculoskeletal radiologist. The study included 61 boys and 39 girls with a mean age of 10 (range 4–14) years. The most common fracture observed was the juxta-epiphyseal type II fracture (53%), followed by the Salter–Harris type II fracture (26%). Other fractures observed included Salter–Harris type I (4%), Salter–Harris type IV (5%), juxta-epiphyseal type I (8%), transverse metaphyseal (2%) and oblique metaphyseal (2%).

There are known racial variations in the branching and furcation pattern and the length of the facial nerve (FN) trunk and hardly any studies from the black African population. Surgeries around the FN predispose it to trauma and warrant a detailed anatomy of its branching pattern. Using a descriptive cross-sectional study, a total of 40 FN (20 fresh cadavers) were dissected to record the pattern and length of the FN. The frequency of various patterns of FN using the Davis et al classification was as follows: type I: 10 (25%), type II: 9 (22.5%), type III: 7 (17.5%), type IV: 6 (15%), type V: 2 (5%), and type VI: 6 (15%). The nerve bifurcated in 32(80%) and trifurcated in 8(20%) of the cadavers. There was no statistical difference in the branching patterns ( p = 0.509) and furcation types ( p = 0.414) between the sides and gender. The length of the trunk of the FN measured from the stylomastoid foramen to the bifurcation point was 16.14(−/+ 3.28 mm). The results from this data established a variation in the anatomical branching pattern of the FN in a black Kenyan population.

On the basis of a high correlation, non-HDL-C (non-high-density lipoprotein cholesterol) and apoB (apolipoprotein B) have been suggested to be of equivalent value for clinical practice; however, the strength of this relationship has not been examined in detail in patients with dyslipidaemia. The present study examines the variance of non-HDL-C compared with apoB in 1771 consecutive patients evaluated in a lipid clinic. These patients were divided into normolipidaemic subjects (n=407), type I hyperlipoproteinaemia (n=16), type IIa (n=736) and IIb (n=231) hyperlipoproteinaemia, type III hyperlipoproteinaemia (n=38), type IV hyperlipoproteinaemia (n=509) and type V hyperlipoproteinaemia (n=101). The relationship between non-HDL-C and apoB was examined both in terms of correlation and concordance. Correlation was high, but concordance was only moderate in the normolipidaemic subjects and in those with type IIa and type IIb hyperlipoproteinaemia. Correlation and concordance were both low in the subgroups with type III and type V hyperlipoproteinaemia. In those with type IV hyper-lipoproteinaemia, correlation was moderately high (r=0.74), but concordance was only fair. In conclusion, our results indicate that there is substantial variance of apoB for given values of non-HDL-C in many dyslipidaemic subjects. It follows that correlation is not adequate as a sole judge of equivalence of laboratory parameters.

To define the relationship between renal vascular development and renin distribution during kidney ontogeny, the complete renal arterial tree of Sprague Dawley rats during fetal (20 d) and postnatal (1 to 90 d) life was microdissected and immunostained for renin. A shift in renin distribution from interlobar and arcuate arteries in the fetus to the afferent arterioles in the adult was observed. In addition, seven types of renin distribution along the afferent arterioles were identified. In type I, renin was distributed continuously along the whole length of the afferent vessel. This pattern was most frequently observed in the fetus. In type II, renin extended upstream from the glomerulus but did not occupy the whole length of the arteriole. This type was relatively constant throughout postnatal life. In type III, renin was present as bands along the afferent vessel; it was most frequently observed in the fetal and early perinatal periods. In type IV, renin was restricted to the "classical" juxtaglomerular localization. It was the most frequent type observed in the adult rat. In type V, no renin was found in the arteriole. It was the second most frequent type observed in the adult rat. In addition, two "mixed" patterns, type III/IV and type III/II, were occasionally observed. The distribution of renin-expressing cells was spatially and temporally associated with the development of blood vessels. Development of a new arterial branch was preceded by the appearance of renin-expressing cells at the point of branching. This was followed by an outpouching of the arterial wall that progressively elongated to form a new arteriole. During this process, renin-expressing cells were distributed along the whole of the newly formed vessel. As the vessel matured, renin-expressing cells became restricted to the juxtaglomerular portion of the afferent arteriole. It is concluded that throughout life and within each individual arterial tree, expression of renin is heterogeneous, following patterns that are unique for each developmental stage. Furthermore, the association of renin-expressing cells with branching of renal arterioles suggests a role for these cells in the development of the kidney vasculature.
