Types and Evolution of Columbite-Group Minerals from Pegmatites in the Chinese Altai, NW China: Implications for Regional Petrogenesis and Rare-Element Mineralization
Authors: Zhou Qifeng , Qin Kezhang , Tang Dongmei 
Published: March 2024

Abstract
The Chinese Altai orogenic belt is famous for large numbers of pegmatite dikes, various rare-element (REL) mineralization types and its rich REL resources. In REL pegmatites, columbite-group minerals (CGM) display compositional complexity that can be used to decipher magma evolution and REL metallogenesis. Here, we provide compositional data and internal structures for columbite-group minerals from representative Chinese Altai REL pegmatites, including Koktokay No. 3 (Li-Be-Nb-Ta-Cs-Rb-Hf, early Jurassic), Xiaokalasu (Li-Nb-Ta, late Permian), and Dakalasu (Be-Nb-Ta, middle Triassic), in order to elucidate ore-forming processes and identify possible indicators of REL mineralization to enhance exploration success. The CGM were classified into five types based on compositional complexity, each of which provides a window into magmatic evolution and crystallization in the pegmatite. In the Koktokay No. 3 pegmatite, CGM evolution in zone I reveals a silicate melt with fluid at undercooling, while that in zone IV reflects a silicate melt followed by complex Ta-rich boundary-layer melt, and that in zone V suggests an evolution from silicate melt, to Ta-rich boundary-layer melt, and finally to REL-rich and fluxed melt accompanied by fluid activity. In the Xiaokalasu Li-mineralized pegmatite, CGM display a similar evolution trend to that of core-rim CGM in zone V of the Koktokay No. 3 pegmatite. In the Dakalasu pegmatite, CGM and Ti-Nb-Ta phases imply Fe-Mn-Nb-Ta-rich and Ti-Nb-Ta-rich melts, and intergrowths of CGM, Ta/Nb-rich rutile, and microlite result from decomposition of a metastable Ti-Nb-Ta oxide precursor in undercooling conditions. The Nb-Ta and Fe-Mn fractionation and changes in minor/trace element contents in CGM depend on the geochemical features of the elements, chemistry of the pegmatite magma, petrogenetic processes (e.g., fractional crystallization, fluid exsolution, and melt–fluid–mineral interaction), and buffering of these factors. Fractional crystallization prevailed during melt evolution, producing Ta-rich boundary-layer melt and REL-rich and flux-enriched melt. Fluid activity was observed in zones related to magmatic, magmatic–hydrothermal transitional, and hydrothermal stages, leading to CGM chemical redistribution by similar/low-Ta and high-Sb fluid replacement and crystallization of stibiotantalite. Fractional crystallization, host-rock assimilation, rapid undercooling, fluid exsolution, and fluid activity are important for Be, Li, Nb, and Ta mineralization. Combining the potential indicators [i.e., Nb-Ta-oxide phase assemblage, CGM types and evolution, twin-element decoupling (Zr-Hf, Th-U, and Y-REE), trace element content grade, and REE (rare earth element) distribution pattern] could be used to discriminate REL mineralization types and enhance REL exploration success.

Published: March 2024

Incorporar tecnología en el aprendizaje supone, no solamente el conocimiento y el dominio de los recursos disponibles en línea, implica la definición de competencias a desarrollar en los estudiantes: habilidades, actitudes y valores; diseño de estrategias de enseñanza, aprendizaje e instrumentos de evaluación, partiendo de lo que se conoce como diseño curricular inverso. Así, las aplicaciones tecnológicas a emplear en cada estrategia son solamente herramientas que facilitan el logro de los fines formativos. La selección idónea depende del conocimiento exhaustivo que como docentes se tienen de los estudiantes, de sus necesidades y de sus características; del entorno, de la institución, y de los recursos con que se cuentan, así como de un diseño curricular previo que responda a las competencias que se requieren desarrollar. Esta investigación describe la falta de comprensión de los conceptos de currículum, diseño curricular inverso y análisis curricular sistémico por parte de los 22 estudiantes de la Maestría en Tecnología Educativa de la UPAEP. La metodología utilizada fue investigación-acción, para transformar la práctica docente de los estudiantes mediante un plan de intervención basado en competencias, que fomentaron la comprensión de los conceptos y que los prepararon a efectuar eficientemente el diseño curricular apoyado por tecnología.

Published: March 2024

BackgroundThis study aimed to evaluate targeted axillary dissection in node locally advanced node positive breast cancer patients with complete pathological response to neoadjuvant chemotherapy.Patients and methodsThis is a prospective cohort study including 25 females diagnosed with locally advanced breast cancer with proven lymph node involvement who had complete pathological response to the neoadjuvant chemotherapy regarding the clipped previously involved lymph node. Lymph node biopsy and frozen section of the clipped lymph node after wire localization and the sentinel lymph node after patent blue dye injection was done. This is followed by paraffin section examination of the lymph node biopsy and 6 months follow-up for the patients.ResultsTwenty-four patients out of 25 patients had successful localization of the clipped and sentinel lymph node with no macrometastasis detected in frozen section. Twenty-two out of the 24 patients had no micrometastasis in paraffin section. Two of the 24 patients had micrometastasis on paraffin section and required axillary radiotherapy. One of the 25 patients failed localization of the clipped lymph node and received conventional axillary lymph node dissection. Two patients developed lymphedema, one of them after axillary radiotherapy, and the other one after axillary lymph node dissection.ConclusionThe combination of targeted axillary dissection and sentinel lymph node biopsy can replace axillary clearance in patients with node positive locally advanced breast cancer with complete pathological response to neoadjuvant chemotherapy.

Published: March 2024

PurposeThe controversy of treatment of acute colonic obstruction between the classical Hartmann’s procedure (HP) and the on-table lavage technique with primary colorectal anastomosis (PCA) for a safe, tolerable, and definitive operation with the least complications is still standing. So we conducted this prospective study to distinguish between both techniques as regards the efficacy and safety.MethodsIn group A (n_ 30) the conventional Hartmann’s procedure was done by colonic resection and construction of left-sided stoma. In the B group (n_ 30), colonic resection was followed by colonic lavage, then a primary two-layered anastomosis with covering ileostomy was performed.ResultsThe whole postoperative outcomes were comparable between both techniques.ConclusionsWe believe that on table lavage technique with colorectal anastomosis is a notable choice during the treatment of acute obstruction of the left colon.

Published: March 2024

BACKGROUND
Pancreaticoduodenectomy (PD) is a technically complex operation, with a relatively high risk for complications. The ability to rescue patients from post-PD complications is as a recognized quality measure. Tailored protocols were instituted at our low volume facility in the year 2013.
AIM
To document the rate of rescue from post-PD complications with tailored protocols in place as a measure of quality.
METHODS
A retrospective audit was performed to collect data from patients who experienced major post-PD complications at a low volume pancreatic surgery unit in Trinidad and Tobago between January 1, 2013 and June 30, 2023. Standardized definitions from the International Study Group of Pancreatic Surgery were used to define post-PD complications, and the modified Clavien-Dindo classification was used to classify post-PD complications.
RESULTS
Over the study period, 113 patients at a mean age of 57.5 years (standard deviation [SD] ± 9.23; range: 30-90; median: 56) underwent PDs at this facility. Major complications were recorded in 33 (29.2%) patients at a mean age of 53.8 years (SD: ± 7.9). Twenty-nine (87.9%) patients who experienced major morbidity were salvaged after aggressive treatment of their complication. Four (3.5%) died from bleeding pseudoaneurysm (1), septic shock secondary to a bile leak (1), anastomotic leak (1), and myocardial infarction (1). There was a significantly greater salvage rate in patients with American Society of Anesthesiologists scores ≤ 2 (93.3% vs 25%; P = 0.0024).
CONCLUSION
This paper adds to the growing body of evidence that volume alone should not be used as a marker of quality for patients requiring PD. Despite low volumes at our facility, we demonstrated that 87.9% of patients were rescued from major complications. We attributed this to several factors including development of rescue protocols, the competence of the pancreatic surgery teams and continuous, and adaptive learning by the entire institution, culminating in the development of tailored peri-pancreatectomy protocols.

Authors: Ostapenko Alexander , Stroever Stephanie , Eyasu Lud , Kim Minha , Aploks Krist , Dong Xiang Da , Seshadri Ramanathan 
Published: March 2024

BACKGROUND
Resection of hepatic metastasis from neuroendocrine tumors (NETs) improves quality of life and prolongs 5-year survival. Ablation can be utilized with surgery to achieve complete resection. Although several studies report long-term outcomes for patients undergoing ablation, none have explored perioperative effects of ablation in patients with metastatic NETs.
AIM
To determine if intra-operative ablation during hepatectomy increases risk of adverse outcomes such as surgical site infections (SSIs), bleeding, and bile leak.
METHODS
A retrospective analysis of the hepatectomy National Surgical Quality Improvement Program database from 2015-2019 was performed to determine the odds of SSIs, bile leaks, or bleeding in patients undergoing intraoperative ablation when compared to hepatectomy alone.
RESULTS
Of the 966 patients included in the study, 298 (30.9%) underwent ablation during hepatectomy. There were 78 (11.7%) patients with SSIs in the hepatectomy alone group and 39 (13.1%) patients with a SSIs in the hepatectomy with ablation group. Bile leak occurred in 41 (6.2%) and 14 (4.8%) patients in the two groups, respectively; bleeding occurred in 117 (17.5%) and 33 (11.1%), respectively. After controlling for confounding variables, ablation did not increase risk of SSI (P = 0.63), bile leak (P = 0.34) or bleeding (P = 0.07) when compared to patients undergoing resection alone on multivariate analysis.
CONCLUSION
Intraoperative ablation with hepatic resection for NETs is safe in the perioperative period without significant increased risk of infection, bleeding, or bile leak. Surgeons should utilize this modality when appropriate to achieve optimal disease control and outcomes.
Etanercept-synthesizing adipose-derived stem cell secretome: A promising therapeutic option for inflammatory bowel disease
Authors: Kim Say-June , Kim Ok-Hee , Hong Ha-Eun , Ju Ji Hyeon , Lee Do Sang 
Published: March 2024

BACKGROUND
Inflammatory bowel disease (IBD) is a chronic inflammatory condition of the gastrointestinal tract, with tumor necrosis factor (TNF)-α playing a key role in its pathogenesis. Etanercept, a decoy receptor for TNF, is used to treat inflammatory conditions. The secretome derived from adipose-derived stem cells (ASCs) has anti-inflammatory effects, making it a promising therapeutic option for IBD.
AIM
To investigate the anti-inflammatory effects of the secretome obtained from ASCs synthesizing etanercept on colon cells and in a dextran sulfate sodium (DSS)-induced IBD mouse model.
METHODS
ASCs were transfected with etanercept-encoding mini-circle plasmids to create etanercept-producing cells. The secretory material from these cells was then tested for anti-inflammatory effects both in vitro and in a DSS-induced IBD mouse model.
RESULTS
This study revealed promising results indicating that the group treated with the secretome derived from etanercept-synthesizing ASCs [Etanercept-Secretome (Et-Sec) group] had significantly lower expression levels of inflammatory mediators, such as interleukin-6, Monocyte Chemoattractant Protein-1, and TNF-α, when compared to the control secretome (Ct-Sec). Moreover, the Et-Sec group exhibited a marked therapeutic effect in terms of preserving the architecture of intestinal tissue compared to the Ct-Sec.
CONCLUSION
These results suggest that the secretome derived from ASCs that synthesize etanercept has potential as a therapeutic agent for the treatment of IBD, potentially enhancing treatment efficacy by merging the anti-inflammatory qualities of the ASC secretome with etanercept's targeted approach to better address the multifaceted pathophysiology of IBD.

Published: March 2024

BACKGROUND
Appendiceal mucinous neoplasms (AMNs), although not classified as rare, are relatively uncommon tumors most often discovered incidentally during colorectal surgery. Accurate identification of AMNs is difficult due to non-specific symptoms, overlapping tumor markers with other conditions, and the potential for misdiagnosis. This underscores the urgent need for precision in diagnosis to prevent severe complications.
CASE SUMMARY
This case report describes the unexpected discovery and treatment of a low-grade AMN (LAMN) in a 74-year-old man undergoing laparoscopic hemicolectomy for transverse colon adenocarcinoma (AC). Preoperatively, non-specific gastrointestinal symptoms and elevated tumor markers masked the presence of AMN. The tumor, presumed to be an AMN peritoneal cyst intraoperatively, was confirmed as LAMN through histopathological examination. The neoplasm exhibited mucin accumulation and a distinct immunohistochemical profile: Positive for Homeobox protein CDX-2 , Cytokeratin 20, special AT-rich sequence-binding protein 2, and Mucin 2 but negative for cytokeratin 7 and Paired box gene 8. This profile aids in distinguishing appendiceal and ovarian mucinous tumors. Postoperative recovery was uncomplicated, and the patient initiated adjuvant chemotherapy for the colon AC.
CONCLUSION
This case highlights the diagnostic complexity of AMNs, emphasizing the need for vigilant identification to avert potential complications, such as pseudomyxoma peritonei.
Inhibition of Acid Descaling and Pickling Effects on API 5CT Carbon Steel Using Schiff Base Ligand (C24H21N5O2) in 1 M H2SO4 Solution
Authors: Ugi B. U. 
Published: March 2024

The objective of this paper was to investigate the inhibition of acid descaling and pickling effects on API 5CT carbon steel using Schiff base ligand (C24H21N5O2) in 1 M H2SO4 solution using Potentiodynamic Polarization (PDP), Electrochemical Impedance Spectroscopy (EIS) and Weight Loss (WL) techniques. FTIR spectroscopy shows that there was a strong adsorption of SFBL on the carbon steel surface due to formation of a complex surface film. Corrosion rate of carbon steel decreased exceedingly from 0.0155 to 0.0002 while inhibition efficiency of SFBL rose from 78.8 % to 98.9 % between 20 ppm and 100 ppm respectively. PDP measurements revealed a mixed type inhibitor. EIS measurement reveals that the increasing charge transfer resistance was directly proportional to the increase inhibitor concentration and the double layer capacitance dropped from 1.98 to 0.61 indicating a stronger inhibition.
