Robust interaction of ZnO and TiO2 nanoparticles with layered graphitic carbon nitride for enhanced photocatalytic oxidative desulfurization of fuel oil: mechanism, performance and stability.

Sulfur compounds in fuel such as thiophene, benzothiophene and dibenzothiophene are the primary source of SO x emissions, leading to environmental pollution and acid rain. In this study, we synthesized a layered oxygen-doped graphitic carbon nitride (OCN) structure and integrated ZnO and TiO2 nanoparticles onto the OCN surface through a microwave-assisted sol-gel method. The X-ray photoelectron spectroscopy (XPS) and density functional theory (DFT) results confirmed a robust interaction between the ZnO and TiO2 nanoparticles and the oxygen-doped g-C3N4 (OCN) surface, as indicated by the formation of C-N-Ti and C-O-Ti bonds. This interaction notably improved the optoelectronic properties of the ZnO-TiO2/OCN composite, yielding increased visible light absorption, reduced charge recombination rate, and enhanced separation and transfer of photogenerated electron-hole pairs. The oxygen doping into the CN network could alter the band structure and expand the absorption range of visible light. The ZnO-TiO2/OCN photocatalyst demonstrated remarkable desulfurization capabilities, converting 99.19% of dibenzothiophene (DBT) to dibenzothiophene sulfone (DBT-O2) at 25 °C, and eliminating 92.13% of DBT from real-world fuel oil samples. We conducted in-depth analysis of the factors impacting the redox process of DBT, including the ZnO ratio, initial DBT concentration, catalyst dosage, stability, and O/S molar ratio. Radical trapping experiments established that ˙O2 -, ˙OH and h+ radicals significantly influence the reaction rate. The obtained results indicated that the ZnO-TiO2/OCN photocatalyst represents a promising tool for future fuel oil desulfurization applications.

Billroth-II modified with hinged anti-peristaltic afferent loop versus Roux-en-Y reconstruction after distal gastrectomy for gastric cancer: A propensity-score match analysis.

BACKGROUND: This study aimed to evaluate the effectiveness of modified Billroth-II with a hinged anti-peristaltic afferent loop by comparing it with the Roux-en-Y method. METHODS: We retrospectively analyzed 344 patients with gastric cancer who underwent distal gastrectomy between 2016 and 2021. Propensity score matching was conducted to balance baseline characteristics. RESULTS: After propensity score matching, there were 117 patients in each group. The Billroth-II group was significantly better regarding operating time (184.7 vs 225.3 minutes), postoperative hospital stays (7.9 vs 9.2 days), and time to semi-solid diet tolerance (2.8 vs 3.8 days). The Billroth-II group demonstrated comparable results with the Roux-en-Y group in weight loss, hemoglobin changes, reflux esophagitis, food residue, and gastritis severity. Presentation of bile in gastric remnant was significantly higher in the Billroth-II group (42.9% vs 10.3%). CONCLUSION: There were no significant differences in functional outcomes between Billroth-II and Roux-en-Y reconstructions. The Billroth-II was superior to Roux-en-Y in operating time, hospital stays, and time to semi-solid diet tolerance. The Billroth-II could be considered an acceptable alternative reconstruction after distal gastrectomy.

Improved synthesis, molecular modeling and anti-inflammatory activity of new fluorinated dihydrofurano-naphthoquinone compounds.

A series of new fluorinated dihydrofurano-napthoquinone compounds were sucessfully synthesized in good yields using microwave-assisted multi-component reactions of 2-hydroxy-1,4-naphthoquinone, fluorinated aromatic aldehydes, and pyridinium bromide. The products were fully characterized using spectroscopic techniques and evaluated for their anti-inflammatory activity using lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells. Among 12 new compounds, compounds 8b, 8d, and 8e showed high potent NO inhibitory activity in lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells with IC50 values ranging from 1.54 to 3.92 µM. The levels of pro-inflammatory cytokines IL-1ß and IL-6 in LPS-stimulated RAW264.7 macrophages were remarkably decreased after the application of 8b, 8d, 8e and 8k. Molecular docking simulations revealed structure-activity relationships of 8b, 8d, and 8e toward NO synthase, cyclooxygenase (COX-2 over COX-1), and prostaglandin E synthase-1 (mPGES-1). Further physicochemical and pharmacokinetic computations also demonstrated the drug-like characteristics of synthesized compounds. These findings demonstrated the importance of fluorinated dihydrofurano-napthoquinone moieties in the development of potential anti-inflammatory agents.

Synthesis, in vitro Α-Glucosidase, and acetylcholinesterase inhibitory activities of novel Indol-Fused Pyrano[2,3-D]Pyrimidine compounds.

In this study, new indol-fused pyrano[2,3-d]pyrimidines were designed and synthesized. These products were obtained in moderate to good yields and their structures were assigned by NMR, MS, and IR analysis. Afterwards, the biological important of the products was highlighted by evaluating in vitro for α-glucosidase inhibitory activity as well as acetylcholinesterase (AChE) inhibitory activity. Eleven products revealed substantial inhibitory activity against α-glucosidase enzyme, among which, two most potent products 11d,e were approximately 93-fold more potent than acarbose as a standard antidiabetic drug. Besides that, product 11k exhibited good AChE inhibition. The substituents on the 5-phenyl ring, attached to the pyran ring, played a critical role in inhibitory activities. The biological potencies have provided an opportunity to further investigations of indol-fused pyrano[2,3-d]pyrimidines as potential anti-diabetic agents.

The branching patterns and termination points of the facial artery: a cadaveric anatomical study

Background@#The facial artery is an important blood vessel responsible for supplying the anterior face. Understanding the branching patterns of the facial artery plays a crucial role in various medical specialties such as plastic surgery, dermatology, and oncology. This knowledge contributes to improving the success rate of facial reconstruction and aesthetic procedures. However, debate continues regarding the classification of facial artery branching patterns in the existing literature. @*Methods@#We conducted a comprehensive anatomical study, in which we dissected 102 facial arteries from 52 embalmed and formaldehyde-fixed Vietnamese cadavers at the Anatomy Department, University of Medicine and Pharmacy, Ho Chi Minh City, Vietnam. @*Results@#Our investigation revealed eight distinct termination points and identified 35 combinations of branching patterns, including seven arterial branching patterns. These termination points included the inferior labial artery, superior labial artery, inferior alar artery, lateral nasal artery, angular artery typical, angular artery running along the lower border of the orbicularis oculi muscle, forehead branch, duplex, and short course (hypoplastic). Notably, the branching patterns of the facial artery displayed marked asymmetry between the left and right sides within the same cadaver. @*Conclusion@#The considerable variation observed in the branching pattern and termination points of the facial artery makes it challenging to establish a definitive classification system for this vessel. Therefore, it is imperative to develop an anatomical map summarizing the major measurements and geometric features of the facial artery. Surgeons and medical professionals involved in facial surgery and procedures must consider the detailed anatomy and relative positioning of the facial artery to minimize the risk of unexpected complications.

Long-term Results of Totally Laparoscopic Near-total Gastrectomy for Middle-third Gastric Cancer.

PURPOSE: In recent years, laparoscopic near-total gastrectomy (LnTG) has emerged as a surgical option for gastric cancer in the middle-third of the stomach. However, its application in locally advanced stages presents technical challenges. This study aims to provide a detailed analysis of the operative outcomes and long-term functional and oncological results of totally LnTG in combination with D2 lymphadenectomy for middle-third gastric cancer. PATIENTS AND METHOD: A prospective study was conducted on 79 patients who underwent totally LnTG and D2 lymphadenectomy for middle-third gastric cancer between January 2017 and December 2021. Short-term outcomes included operative characteristics, and the evaluation of gastroesophageal reflux and gastric remnant condition using endoscopy based on the Los Angeles (LA) and Residue-Gastritis-Bile classifications. Long-term oncological outcomes included overall survival and disease-free survival. RESULTS: Totally LnTG was successfully performed in 98.7% of patients without intraoperative complications or conversions to laparotomy. The mean operation time was 202.2±43.0 min, and the median blood loss was 50 (50;100) mL. The overall incidence of postoperative morbidities was 16.5%, with one patient experiencing a narrowing of the gastrojejunostomy, successfully treated by endoscopic balloon dilation. All patients had tumor-free resection margins, and there were no mortalities. The 5-year overall survival and disease-free survival rates were 80% and 55%, respectively. CONCLUSIONS: Totally LnTG is an effective and feasible approach for gastric cancer in the middle-third of the stomach, yielding favorable short-term outcomes and acceptable long-term results. Routine application of totally LnTG for middle-third gastric cancer is practical and promising.

Regional Lymph Node Metastasis Distribution in Resectable Middle-Third Gastric Cancer: A Cross-Sectional Study.

Introduction Lymph node (LN) metastasis happens even in early gastric cancer (GC) even in LN stations that are not adjacent to the primary tumor. Total or subtotal gastrectomy (TG or sTG) can be performed in the middle third of the GC if the negative proximal margin is maintained. These procedures differed in the extent of LN dissection; therefore, oncology considerations must be taken into consideration when selecting the appropriate procedure. Methods This was a cross-sectional study involving 98 patients suffering from middle-third GC. The metastatic lymph nodes (mLN) ratio was calculated in each case by the ratio between the number of mLN and the number of total LNs retrieved. We compare the difference in the total LN retrieved, number of mLN, and rate of positive LN (N+) between the two groups TG and sTG. Results The majority of patients had advanced GC (82.7% pT2-4). About 65.3% of patients had metastasis LN. The events of LN metastasis and skipped LN metastasis happened even in tumors contained in the submucosal layer. The metastasis rates in each LN station were also increasing in correlation with the depth of tumor invasion. For LN station No. 2, 4sa, 10, 11d (which are not mandatory) in sTG, the rate of mLN was 0% for the pT1-3 tumor, regardless of tumor longitudinal location. The rate of mLN for each station was higher in adjacent stations of the tumor (No. 1-3-5-7 in lesser curvature, No. 4sb-4d-6 in greater curvature, No.1-3-4sb in the anterior wall, No. 3-7-12a in the posterior wall). The total LN retrieved, number of mLN, and rate of positive LN were statistically higher in the TG group compared to the sTG group. However, the mean mLN ratios between the two groups were comparable (p = 0.116). Conclusion In accordance with the macroscopic and microscopic characteristics, we observed a stratified distribution of mLN in the middle third of the GC. With these early results, sTG combined with standard lymphadenectomy was an acceptable treatment for T1-T3 middle-third GC in terms of mLN distribution. Total No. 4sb LN dissection might also be reserved in gastrectomy for T1-T3 GC.

Facial artery: anatomical variations in the perioral region in cadavers

Background@#In recent years, there has been an increase in reports of perioral vascular complications resulting from filler injections, such as necrosis of the lip or alar rim, occlusion, and in severe cases, blindness. Conversely, the use of perioral arterial flaps is becoming more prevalent in the treatment of cleft lips, cancer, and trauma. A thorough understanding of perioral arteries is essential to minimize complications and maximize the success of these flaps. However, the course of the facial artery (FA) in the perioral region remains incompletely understood. The aim of this study was to describe the variations of the FA in the perioral region. @*Methods@#We dissected 52 embalmed and formaldehyde-fixed Vietnamese cadavers. We then studied the size and distribution of perioral arteries in 102 specimens. @*Results@#The superior labial artery (SLA) was the most common branch, occurring in 87.25% of cadavers, followed by the inferior labial artery (ILA) at 78.43%. The SLA primarily originated above the mouth corner (cheilion), accounting for 91.01% of cases, and predominantly exhibited a tortuous course within the submucosa (78.65%). The ILA’s branching pattern varied, but it was primarily located below the cheilion (91.25%). The ILA also followed a twisted path, generally within the submucosa. The ILA exhibited two patterns: the typical pattern, distributed at the vermilion border of the lower lip (8.82%), and the horizontal labiomental artery pattern, which ran horizontally in the middle of the lower lip area (69.61%). At their origin, the SLA and ILA had average external diameters of 1.29 mm and 1.28 mm, respectively. @*Conclusion@#Numerous anatomical variations in the FA in the perioral region were found. A detailed anatomic description, suggested landmarks, and angiography before the procedure will be useful to help doctors avoid complications.

Three-year prospective outcomes of laparoscopic intraperitoneal on-lay mesh repair of abdominal incisional hernia.

BACKGROUND: Incisional hernia (IH) can be treated with an intraperitoneal on-lay mesh (IPOM). This study aimed to evaluate the surgical outcomes, recurrence rates, and chronic pain after laparoscopic IH repair. METHOD: The data of 50 patients who underwent laparoscopic IPOM repair between March 2018 and May 2021 were prospectively collected. RESULTS: The standard IPOM technique was used on 41 patients (82%), whereas the IPOM-plus technique was used on nine patients (18%). There was a history of IH repair for 12 patients (24%), and two of them recurrent hernias. The average body mass index was 24.7, and the average defect size was 17.6 cm2 . The mean operative time was 145.7 minutes, and the mean hospital stay was 3.5 days. There were minor complications in nine patients (18%), a case of bowel injury (2%), and a case of bladder injury (2%). Recurrent hernias were observed in three patients (6%) over a mean follow-up period of 17.9 months (4-36 months). One patient had postoperative chronic pain lasting 3 months. The width and size of the hernia were risk factors for recurrence. CONCLUSION: Laparoscopic IPOM repair was a safe and effective method of treating IH, with a low incidence of postoperative complications, chronic pain, and recurrence.

Prevalence and risk factors for human papillomavirus infection among female sex workers in Hanoi and Ho Chi Minh City, Viet Nam: a cross-sectional study

Objective@# Female sex workers (FSWs) are at high risk of human papillomavirus (HPV) infections and cervical cancer due to their high number of sexual partners. The objectives of this study were to determine the prevalence of HPV and identify risk factors for high-risk HPV infection among FSWs in Hanoi and Ho Chi Minh City (HCMC), Viet Nam.@*Methods@#A cross-sectional study was conducted in Hanoi and HCMC between December 2017 and May 2018. We surveyed and screened 699 FSWs aged ≥18 years for HPV infection and abnormal cytology. A multivariable modified Cox regression model was used to determine risk factors for high-risk HPV infection.@*Results@#The overall prevalence of any HPV, high-risk HPV and HPV-16/18 infection in the 699 FSWs was 26.3%, 17.6% and 4.0%, respectively, and were similar in both cities. Multiple infections were identified in 127 participants (69.0%).HPV-52 was the most prevalent (7%), followed by HPV-58 (6%). Abnormal cytology was detected in 91 participants (13.0%). FSWs who are divorced (adjusted prevalence ratio [aPR]: 1.96, 95% confidence interval [CI]: 1.01–3.81), widowed (aPR: 3.26, 95% CI: 1.49–7.12) or living alone (aPR: 1.85, 95% CI: 1.01–3.39) were associated with a higher prevalence of high-risk HPV infection.

A new triterpenoid from the stems of Kadsura coccinea with antiproliferative activity.

A series of schiartane C29 nortriterpenoids with 5/5/7/6/5 membered consecutive rings (1‒5) with an unique schinortriterpenoid skeleton including a new, kadcoccilactone V (1), together with four known ones (2‒5) and three known triterpenoids (6‒8) were identified from stems of Kadsura coccinea (Lem.) A. C. Smith. The structures of 1 and known compounds were elucidated by interpretation of 1D and 2D NMR, and HR-ESI-MS data as well as comparing those data in the literature. All the isolated compounds were examined for cytotoxic effects against six human cancer cell lines [(HCT-15 (colon), NUGC-3 (stomach), NCI-H23 (lung), ACHN (renal), PC-3 (prostate), and MDA-MB-231 (breast)]. Among them, compound 6 showed potent cytotoxicity against NCI-H23 (GI50 1.28 µM) and NUGC-3 (GI50 1.28 µM), and significantly inhibited on PC-3, MDA-MB-231, ACHN, HCT-15 with GI50 values around 2.33 to 2.67 µM.

Biomechanical considerations for uprighting impacted mandibular molars / 대한치과교정학회지

This case report demonstrates two different uprighting mechanics separately applied to mesially tipped mandibular first and second molars. The biomechanical considerations for application of these mechanisms are also discussed. For repositioning of the first molar, which was severely tipped and deeply impacted, a novel cantilever mechanics was used. The molar tube was bonded in the buccolingual direction to facilitate insertion of a cantilever from the buccal side. By twisting the distal end of the cantilever, sufficient uprighting moment was generated. The mesial end of the cantilever was hooked over the miniscrew placed between the canine and first premolar, which could prevent exertion of an intrusive force to the anterior portion of the dentition as a side effect. For repositioning of the second molar, an uprighting mechanics using a compression force with two step bends incorporated into a nickel-titanium archwire was employed. This generated an uprighting moment as well as a distal force acting on the tipped second molar to regain the lost space for the first molar and bring it into its normal position. This epoch-making uprighting mechanics could also minimize the extrusion of the molar, thereby preventing occlusal interference by increasing interocclusal clearance between the inferiorly placed two step bends and the antagonist tooth. Consequently, the two step bends could help prevent occlusal interference. After 2 years and 11 months of active treatment, a desirable Class I occlusion was successfully achieved without permanent tooth extraction.

Comparison of Novel, Bach Mai Boston Tool (BBT) and the Patient-Generated Subjective Global Assessment (PG-SGA) for Oncology Inpatients.

Oncology inpatients are at high risk of malnutrition. Identification of at risk patients by nutrition screening requires a practical and easy to use tool. The aim of this study was to determine the validity of the Bach Mai Boston Tool (BBT) compared to a 'gold standard' full nutrition assessment using the Patient-Generated Subjective Global Assessment (PG-SGA). A cross-sectional study was conducted on 270 oncology inpatients from January to December 2016. Cohen's Kappa, sensitivity, specificity and ROC analyses were performed. 270 inpatients were included in this study with a mean age of 56.3 ± 12.1 years old. Of these patients, 51.8% were male, and 74.1% had gastrointestinal cancer. The mean body mass index of patients was 20.6 ± 3.0 kg/m2. The PG-SGA tool identified 146 (54.1%) malnourished patients, while the BBT identified 105 (39.9%) malnourished patients. The BBT had a medium consistency, with a Kappa value of 0.6. Using a cut-off point of ≥ 4, the BBT had a sensitivity of 87.7% and a specificity of 72.6%. On the other hand, a BBT with a cut-off point ≥ 5 resulted in a sensitivity of 67.1%, a specificity of 94.4%, and an AUC of 0.81. The BBT is a practical, informative and valid tool for detecting malnutrition in hospitalized oncology patients. We recommend using a cut-off point of 4 for screening the risk of malnutrition for oncology inpatients.

High hepatitis C virus infection among female sex workers in Viet Nam: strong correlation with HIV and injection drug use

@#Abstract Objective: The World Health Organization’s guidelines on viral hepatitis testing and treatment recommend prioritizing high prevalence groups. Hepatitis C virus (HCV) infection disproportionately affects people who inject drugs and men who have sex with men, but data on female sex workers (FSW) are limited. The study aimed to determine active HCV infection and risk factors associated with HCV exposure among Vietnamese FSW. Methods: We surveyed 1886 women aged ≥ 18 years from Haiphong, Hanoi and Ho Chi Minh City who had sold sex in the last month. We tested for HCV antibody and HCV core antigen as markers for exposure to HCV and active infection, respectively. Results: Across these provinces, high prevalence of HCV exposure (8.8–30.4%) and active infection (3.6–22.1%) were observed. Significant associations with HCV exposure were HIV infection (aOR = 23.7; 95% CI: 14.8–37.9), injection drug use (aOR = 23.3; 95% CI: 13.1–41.4), history of compulsory detention (aOR = 2.5; 95% CI: 1.4–4.2) and having more than 10 sex clients in the last month (aOR = 1.9; 95% CI: 1.2–3.2). Among FSW who reported never injecting drugs, HIV infection (aOR = 24.2; 95% CI: 14.8–39.4), a history of non-injection drug use (aOR = 3.3, CI: 1.8–5.7), compulsory detention (aOR = 2.2; 95% CI: 1.2–4.0) and having over 10 sex clients in the last month (aOR = 2.2, 95% CI: 1.3–3.7) were independently associated with HCV exposure. Discussion: FSW have elevated HCV risks through sex- and drug-related pathways. These findings highlight the need to offer FSW-targeted HCV interventions and ensure their access to HIV prevention and treatment.

Pilot scale degradation of mono and multi volatile organic compounds by surface discharge plasma/TiO2 reactor: Investigation of competition and synergism.

This paper mainly deals with the isovaleraldehyde degradation with the help of a nonthermal plasma surface discharge (NPSD) coupled with photocatalysis. The efficiency of NPSD reactor, for gas treatment, was studied for different binary mixtures: (1) mixture of aldehydes (Isovaleraldehyde and Butyraldehyde) and (2) mixture of aldehyde and amine (Isovaleraldehyde and Trimethylamine). A planar continuous reactor is used to investigate the effect of addition of another pollutant on the performance of oxidation process. A synergetic effect was observed by combining NPSD and photocatalysis for the degradation of mixture of pollutants. In addition, combined NPSD/photocatalysis has significantly enhanced the CO2 selectivity, as compared to NPSD alone. This is attributed to the formation of more reactive species due to the presence of TiO2 in the plasma discharge zone. Moreover, ozone and UV light on TiO2, produced by plasma, have activated the surface leading to enhanced mineralization. In addition, the byproducts of each binary mixture were identified and evaluated.

Molecular epidemiology and antimicrobial resistance phenotypes of Acinetobacter baumannii isolated from patients in three hospitals in southern Vietnam.

Multidrug resistance in the nosocomial pathogen Acinetobacter baumannii limits therapeutic options and impacts on clinical care. Resistance against carbapenems, a group of last-resort antimicrobials for treating multidrug-resistant (MDR) A. baumannii infections, is associated with the expression (and over-expression) of carbapenemases encoded by the blaOXA genes. The aim of this study was to determine the prevalence of antimicrobial-resistant A. baumannii associated with infection in three hospitals in southern Vietnam and to characterize the genetic determinants associated with resistance against carbapenems. We recovered a total of 160 A. baumannii isolates from clinical samples collected in three hospitals in southern Vietnam from 2012 to 2014. Antimicrobial resistance was common; 119/160 (74 %) of isolates were both MDR and extensively drug resistant (XDR). High-level imipenem resistance (>32 µg ml-1) was determined for 109/117 (91.6 %) of the XDR imipenem-nonsusceptible organisms, of which the majority (86.7 %) harboured the blaOXA-51 and blaOXA-23 genes associated with an ISAba1 element. Multiple-locus variable number tandem repeat analysis segregated the 160 A. baumannii into 107 different multiple-locus variable number tandem repeat analysis types, which described five major clusters. The biggest cluster was a clonal complex composed mainly of imipenem-resistant organisms that were isolated from all three of the study hospitals. Our study indicates a very high prevalence of MDR/XDR A. baumannii causing clinically significant infections in hospitals in southern Vietnam. These organisms commonly harboured the blaOXA-23 gene with ISAba1 and were carbapenem resistant; this resistance phenotype may explain their continued selection and ongoing transmission within the Vietnamese healthcare system.

The evaluation of the esophagoduodenal reflux by scintigraphy. Used 99m Tc-HIDA and gamma-camera found that as a simple, physiological acceptable method and could be used for quantitative analysis. The method of the esophago-intestinal anastomosis type omega after the total gastrectomy can remainly cause the reflux. The method of making the pseudo stomach type lygidakis with distance of 40 cm from the anastomosis stoma Roux -en-Y to the anastomosis stoma of the esophagointestine found that it can prevent the esophagoduodenal reflux. The reflux found that did not occure in all 31 patients who evaluted by scintigraphy.

Study on the gastric emptying times in patients with total gastrectomy by CT scanner

CT scanner with marking 99m Tc-DTPA, with semi-solid meal can study completely the movement of food in the gastric region in the physiological condition and determine the gastric emptying times. The ability of rapid movement of the food from omega loop (t50% = 25.42 minutes) and the time of retention of the food in the false stomach in patients with total gastrectomy were the same as this in persons with the normal stomach (t50%=49.23 minutes). This accounted for the better living condition and less disorder in patients with gastric replacement by false stomach as type of Lygidakis total gastrectomy.
