Authors: Peng Jian-Xin , Li Hui-Long , Ye Qing , Mo Jia-Qiang , Wang Jian-Yi , Liu Zhang-Yuanzhu , He Jun-Ming
Published: November 2024

BACKGROUND

Laparoscopic hepatectomy is a proven safe and technically feasible approach for liver tumor resection, but laparoscopic anatomical SVIII resection (LASVIIIR) remains rarely reported due to poor accessibility, difficult exposure, and the deep-lying Glissonean pedicle. This study examined the safety, feasibility, and perioperative outcomes of LASVIIIR via a middle hepatic fissure approach at our institution.

AIM

To investigate the safety, feasibility, and perioperative outcomes of LASVIIIR via a middle hepatic fissure approach at our institution.

METHODS

From November 2017 to December 2022, all patients with a liver tumor who underwent LASVIIIR were enrolled. The perioperative outcomes and postoperative complications were evaluated.

RESULTS

Thirty-four patients underwent LASVIIIR via a middle hepatic fissure approach from the side or cranio side and were included. The mean operation time was 164 ± 54 minutes, and the intra-operative blood loss was 100 mL (range: 20-1000 mL). The mean operative times were, respectively, 152 ± 50 minutes and 222 ± 29 minutes (P = 0.001) for the caudal side and cranial side approaches. In addition, the median blood loss volumes were 100 mL (range: 20-300 mL) and 250 mL (range: 20-1000 mL), respectively, for the caudal and cranial sides (P = 0.064). Three patients treated using the cranial side approach experienced bile leakage, while 1 patient treated using the caudal side approach had subphrenic collection and underwent percutaneous drainage to successfully recover. There were no differences regarding postoperative hospital stays for the caudal and cranial side approaches [9 (7-26) days vs 8 (8-19) days] (P = 0.226).

CONCLUSION

LASVIIIR resection remains a challenging operation, but the middle hepatic fissure approach is a reasonable and easy-to-implement technique.
Analysis of the efficacy and safety of endoscopic retrograde cholangiopancreatography for the treatment of pediatric pancreatobiliary diseases
Authors: Wang Xue-Qi , Kong Chi-Huan , Ye Mao , Diao Mei
Published: November 2024

BACKGROUND

Traditional surgical procedures are highly invasive and risky for children with pancreatic and biliary diseases. Endoscopic retrograde cholangiopancreatography (ERCP) has been used mostly in adults because it is a safe and effective surgical procedure. Its application in children will contribute to the treatment and prognosis of children with pancreatic and biliary diseases.

AIM

To analyze the efficacy and safety of ERCP for the treatment of pediatric pancreatobiliary diseases.

METHODS

A retrospective study was performed using the medical records of 101 pediatric patients who received treatment for pancreatobiliary diseases at Children’s Hospital Capital Institute of Pediatrics from April 2022 to April 2024. The patients were divided into an observation group (n = 52, treated with ERCP) and a control group (n = 49, treated with traditional surgical methods). Diagnostic and therapeutic outcomes of ERCP were statistically analyzed. Treatment efficacy, time to resume eating, and hospital stay duration were compared between the two groups. Indicators of liver function were monitored preoperatively and one week postoperatively. Dynamic changes in C-reactive protein (CRP) and serum amylase levels were assessed preoperatively and at 6 and 24 hours postoperatively. Postoperative complications were also compared. Logistic multivariate regression was used to analyze the independent effect of ERCP on outcomes.

RESULTS

For the observation group, 36 and 16 patients were diagnosed with biliary and pancreatic diseases, respectively. Compared with the control group, the observation group exhibited a higher overall effective rate (P < 0.05), shorter times to resume eating, shorter hospital stays (P < 0.05), and significantly improved postoperative liver function (P < 0.05). CRP and serum amylase levels were significantly increased in both groups at 6 and 24 hours postoperatively (P < 0.05), but were significantly lower in the observation group (P < 0.05). The observation group also had a lower incidence of complications (P < 0.05). ERCP was an independent factor affecting treatment efficacy, length of hospital stay, total bilirubin, aspartate aminotransferase, and alanine aminotransferase, CRP, serum amylase, and the occurrence of complications in children with pancreaticobiliary diseases (P < 0.05).

CONCLUSION

ERCP effectively enhances the treatment efficacy of pediatric pancreatobiliary diseases, with a reduced inflammatory response, faster postoperative recovery, and fewer complications. ERCP is a safe and effective diagnostic and therapeutic method for pediatric pancreatobiliary diseases.

Authors: Xing Guo-Dong , Wang Xian-Qiang , Duan Lian , Liu Gang , Wang Zheng , Xiao Yuan-Hong , Xia Qiao , Xie Hua-Wei , Shen Zhou , Yu Zhen-Zhu , Huang Liu-Ming
Published: November 2024

BACKGROUND

The Kasai procedure (KPE) is an important treatment for biliary atresia (BA), the most common cause of neonatal obstructive jaundice.

AIM

To investigate the efficacy of robotic-assisted Kasai portoenterostomy (RAKPE) in patients with BA.

METHODS

Clinical data of 10 patients with BA who underwent RAKPE at the Seventh Medical Center of the People's Liberation Army General Hospital between December 2018 and December 2021 were retrospectively analyzed. One patient underwent Open Kasai portoenterostomy (OKPE) due to intraoperative bleeding. Consequently, nine patients were included in this study. Fifty-two patients who underwent OKPE during the same period served as the control group. Preoperative and postoperative biochemical indexes, surgery-related indexes, and postoperative clearance of jaundice (CJ) were recorded and statistically analyzed.

RESULTS

RAKPE was successfully completed in all nine patients, with an average total operative time of 352.2 minutes (including intraoperative cholangiography). Milk feeding resumed on an average 9.89 days postoperatively, and the average time of drainage tube removal was 18.11 days. All patients were followed up for 6 months to 2 years. The liver function indicators and bilirubin levels in 8 patients returned to normal within 3 months after surgery. Three patients developed recurrent cholangitis after discharge, with elevated white blood cell counts, liver function indicators, and bilirubin levels, requiring hospitalization for intravenous antibiotic treatment. The duration of cholangitis ranged from 5 to 8 months post-surgery. To date, no subsequent cases of cholangitis have occurred. All patients have normal liver function and bilirubin levels, with no intrahepatic bile duct dilatation on ultrasonography. Statistical analysis comparing these indicators with those of patients who underwent OKPE showed that the RAKPE group had longer operative times and postoperative drainage tube removal durations. However, there were no significant differences in intraoperative blood loss, postoperative oral milk intake resumption, postoperative hospital stay, or CJ at 3 months post-surgery.

CONCLUSION

RAKPE is technically feasible, safe, and effective for treating BA. Once the technique is mastered, RAKPE may achieve CJ outcomes comparable to those of OKPE.
Comparative analysis of conventional laparoscopic surgery and single-incision laparoscopic surgery in gastric cancer treatment: Outcomes and prognosis
Authors: Cao Ce , Tian Xue , Wang Xue-Zhao , Wang Qing
Published: November 2024

BACKGROUND

Gastric cancer surgery has advanced with minimally invasive techniques. This study compares outcomes between single-incision laparoscopic surgery plus one port (SILS + 1) and conventional laparoscopic surgery (CLS) in treating gastric cancer.

AIM

To explore the curative effect of SILS + 1 and CLS on gastric cancer and their influences on prognosis.

METHODS

A total of 93 patients with gastric cancer undergoing radical gastrectomy in the hospital were retrospectively analyzed between September 2019 and September 2022. According to different surgical methods, they were divided into SILS + 1 group (n = 56) and CLS group (n = 37). The perioperative indexes, pain degree [visual analogue scale (VAS)] and stress response [C-reactive protein (CRP), white blood cell count (WBC)] in the two groups were compared. The postoperative complications, recurrence rate and mortality at 1 year after surgery were recorded.

RESULTS

Intraoperative blood loss was significantly lower in the SILS + 1 group (76.53 ± 8.12 mL) compared to the CLS group (108.67 ± 12.34 mL, P < 0.001), and the total incision length was also significantly shorter in the SILS + 1 group (5.29 ± 1.01 cm vs 9.45 ± 2.34 cm, P < 0.001). SILS + 1 patients experienced faster recovery, with shorter times to first flatus (1.94 ± 0.43 days vs 3.23 ± 0.88 days, P < 0.001) and ambulation (2.76 ± 0.58 days vs 4.10 ± 0.97 days, P < 0.001). Postoperative pain, as measured by VAS scores, was significantly lower in the SILS + 1 group on postoperative days 1, 2, and 3 (P < 0.001). Additionally, stress markers (CRP and WBC) were significantly lower in the SILS + 1 group on the first postoperative day (CRP: 6.41 ± 1.63 mg/L vs 7.82 ± 1.88 mg/L, P < 0.001; WBC: 6.34 ± 1.50 × 109/L vs 7.09 ± 1.61 × 109/L, P = 0.024). The complication rate in the SILS + 1 group was also significantly lower than in the CLS group (8.93% vs 27.03%, P = 0.020). However, there was no significant difference in recurrence rates between the two groups after one year (3.57% vs 8.11%, P > 0.05).

CONCLUSION

SILS + 1 and CLS have the comparable lymph node clearance effect in patients with gastric cancer. However, SILS + 1 is more beneficial to reduce intraoperative blood loss, relieve pain, alleviate stress response, reduce the incidence of complications and promote rapid postoperative recovery.
Recurrent small intestinal perforation from gastric mucosal heterotopia: A case report
Authors: Li Zhi-Wang , Jiang Tao-Feng , Yang Cheng-Kun , Xu Zhi-Jie , Zhu Wen-Biao , Li En
Published: November 2024

BACKGROUND

Gastric mucosal heterotopia (GMH) is a rare, typically asymptomatic condition characterized by ectopic gastric mucosa in tissues outside the stomach. However, it can lead to severe complications, including small intestinal perforation. This case report highlights the unique clinical presentation of GMH-induced recurrent small intestinal perforations, which has been rarely documented. These findings emphasize the importance of considering GMH in patients with unexplained recurrent gastrointestinal perforations.

CASE SUMMARY

A 13-year-old female presented with acute abdominal pain. Her medical history included four prior surgeries for small intestinal perforations. Enhanced computed tomography revealed localized bowel thickening and perforation, prompting emergency surgery. A 20 cm segment of the ileum was resected and anastomosed. Pathological analysis confirmed extensive GMH with ulceration and perforation, identifying GMH as the cause of the recurrent perforations. Postoperatively, the patient recovered well with no recurrence by the 10-month follow-up.

CONCLUSION

GMH should be considered in cases of recurrent unexplained intestinal perforations.
Pathological diagnosis and clinical feature analysis of descending duodenal mucosal adenocarcinoma: A case report
Authors: Zhang Jin-Yuan , Wu Liu-Sheng , Yan Jun , Jiang Qiang , Li Xiao-Qiang
Published: November 2024

BACKGROUND

Mucosal adenocarcinoma of the descending duodenum is a very rare gastrointestinal tumor. Due to its low incidence, it has rarely been the focus of clinical and pathological studies. The clinical manifestations of these tumors are usually nonspecific, and they are easily misdiagnosed or missed. Pathological diagnosis is the gold standard for diagnosis, but due to the small number of cases, the relevant pathological characteristics and diagnostic criteria are not completely clear. The purpose of this study was to deepen the understanding of the diagnosis and treatment of this disease and to provide a clinical guidance.

CASE SUMMARY

A 61-year-old woman who was hospitalized with recurrent abdominal pain for more than 20 days. The patient developed epigastric pain with no obvious cause more than 20 days prior, mainly left epigastric pain and middle epigastric pain, and presented persistent dull pain without nausea or vomiting, fever or chills. The patient was treated at a local hospital, gastroscopy revealed a new lesion in the circum-intestinal cavity in the descending part of the duodenum, and pathological biopsy revealed mucous adenocarcinoma in the descending part of the duodenum. Currently, for further diagnosis and treatment, the patient is admitted to our hospital for surgical treatment for “malignant tumor of the duodenum” in the outpatient department.

CONCLUSION

Mucosal adenocarcinoma of the descending duodenum has a high misdiagnosis rate and missed diagnosis rate, clinical manifestations lack specificity, and pathological diagnosis is the main basis for diagnosis.
The Cape Town Convention and the Law of State Immunity
Authors: Webb Philippa
Published: November 2024

Based on the keynote speech at the 11th Conference of the Cape Town Convention Academic Project, this article considers the role of public international law, in particular the law of state immunity, in the interpretation and application of the Cape Town Convention. After setting out the legal framework of state immunity, it traces the reasoning process for determining whether an entity such as a state-owned airline is entitled to immunity from jurisdiction and immunity from enforcement. It reflects on the relationship between the Convention and the law of state immunity as enshrined in domestic and international law and also on the implications of the absence of a dedicated dispute settlement mechanism under the Convention.
Rewizje – korekty – idiolekty. Dwie francuskie wycieczki w stronę Lambra i Kordiana
Authors: Puchalska Iwona
Published: November 2024

Punktem wyjścia artykułu jest Goetheańskie założenie, że międzykulturowa wymiana w obrębie Weltliteratur może zaowocować wzajemnymi „korektami” rozumienia, oceny, wartościowania. Lambro i Kordian, dwa specyficznie powiązane ze sobą teksty Słowackiego, zostały w związku z tym usytuowane w kontekście francuskim, rozumianym nie genetycznie, lecz odbiorczo. Analizie zostały poddane dwa różnego typu komentarze literaturoznawcze, z których jeden jest przykładem recepcyjnego pośrednictwa reprezentanta kultury polskiej na emigracji, drugi – elementem francuskiego literaturoznawstwa (są to: wstęp Wenceslasa Gasztowtta do francuskiego przekładu dzieł Słowackiego z lat 60. XIX wieku oraz artykuł Le drame romantique : le héros et l’histoire dans « Le Prince de Hombourg » de Kleist, « Kordian » de Słowacki et « Lorenzaccio » de Musset autorstwa Danièle Chauvin z 2000 roku). Teksty te, powstałe w rozmaitych celach i różnych okresach, łączy wspólne pole odniesień porównawczych (w tym szkic George Sand O dramacie fantastycznym), zarazem jednak różni odmienna kontekstualizacja kulturowa oraz odmienne usytuowanie względem legendy mickiewiczowskiej, co sprawia, że dostarczają niestandardowych impulsów interpretacyjnych, ożywczych w stosunku do dominujących dzisiaj sposobów lektury Lambra i Kordiana.

Revisions – Adjustments – Idiolects. Two French Excursions towards Lambro and Kordian:
The point of departure of the article is the Goethean assumption that intercultural exchange within Weltliteratur can result in mutual “adjustments” of understanding, assessment and evaluation. Lambro and Kordian, two specifically related texts by Słowacki, were therefore situated in the French context, understood not in the genetic sense, but in the sense of reception. Two literary commentaries of various types were analysed, one of which is an example of the reception mediation of a representative of Polish culture in exile, the other, an element of French literary studies (these are: the introduction by Wenceslas Gasztowtt to the French translation of Słowacki’s works from the 1860s and the article Le drame romantique : le héros et l’histoire dans « Le Prince de Hombourg » de Kleist, « Kordian » de Słowacki et « Lorenzaccio » de Musset by Danièle Chauvin from 2000). These texts, created for different purposes and in different periods, share a common field of comparative references (including George Sand’s Essai sur le drame fantastique), but at the same time are differentiated by their cultural contextualisation and different location in relation to Mickiewicz’s legend, meaning that they provide non-standard interpretative impulses which are refreshing in relation to today’s dominant ways of reading Lambro and Kordian.
Trabecular Bone Score in Individuals with Chronic Spinal Cord Injury: A Cross-Sectional Study
Authors: Ponzano Matteo , Blencowe Lindsie , Giangregorio Lora M. , Craven B. Catharine
Published: November 2024

Objectives:

To describe lumbar spine (LS) trabecular bone score (TBS) values after SCI, and to explore the differences in fractures risk assessment between FRAX® and TBS-adjusted FRAX® in individuals living with chronic SCI.

Methods:

Baseline dual-energy x-ray absorptiometry (DXA) scans from an established cohort were acquired using a Hologic Discovery QDR 4500. TBS measurements were performed using the TBS iNsightTM software version 2.1.2.0. A Welch's t-test was performed to explore differences in TBS, FRAX®, and TBS-adjusted FRAX® between men and women, between participants ≤49 years and ≥50 years, and between subgroups with and without history of fracture and with complete and incomplete injury.

Results:

We analyzed 37 scans; the mean TBS was 1.336 ± 0.107. The mean 10-year fracture risk was 8.8% ± 11.4% for major osteoporotic fracture and 4.0% ± 10.8% for hip fracture according to FRAX®, and 6.6% ± 2.8% for major osteoporotic fracture and 2.8% ± 6.7% for hip fractures according to TBS-adjusted FRAX®. The 10-year fracture risk for major osteoporotic fractures was higher in individuals with a prior fragility fracture compared to those without, according to FRAX® (p = .033) and TBS-adjusted FRAX® (p = .001).

Conclusion:

Over a half of our sample presented a partially degraded bone microarchitecture based on TBS. TBS was not different between people with motor complete and motor incomplete injury or with and without prior fragility fracture. Future studies are needed to define the clinical relevance of TBS and TBS-adjusted FRAX® in people with chronic SCI.
Prevalence and Impact of Fractures in Persons with Spinal Cord Injuries: A Population-Based Study Comparing Fracture Rates between Individuals with Traumatic and Nontraumatic Spinal Cord Injury
Authors: Ziebart Christina , Jaglal Susan , Guilcher Sara , Matai Lavina , Li Ping , Craven Cathy
Published: November 2024

Background:

Musculoskeletal complications are one of the most common reasons for a patient with a spinal cord injury (SCI) to be rehospitalized. Bone loss due to immobilization and changes in metabolic processes because of the SCI lead to an increased risk of fractures.

Objective:

To evaluate the prevalence and demographic characteristics of people living with an SCI who had a secondary fracture.

Methods:

We used population health administrative data from Ontario, Canada, in individuals with either traumatic (TSCI) or nontraumatic SCI (NTSCI). Records of duplicate cases, missing unique patient identifier numbers, individuals not eligible for provincial health insurance, and age <18 years were excluded. Only records of fractures treated in the emergency department or acute care hospital were included. Descriptive statistics were used to summarize data, using counts and percentages that described the numbers and proportions of fractures by type disaggregated by sex, age groups, and type of SCI.

Results:

A total of 14,168 unique records were identified with 4486 as TSCI and 9682 as NTSCI between April 1, 2004 and March 31, 2020 and were followed up to March 31, 2021. Overall, 11% of the cohort had a subsequent fracture with no difference between TSCI and NTSCI. Hip fractures accounted for 21% of the fractures, wrists accounted for 12%, spine 11%, and tibia 11%. The average time to the first subsequent fracture after the SCI was 3.97 (SD 3.4) years.

Conclusion:

Monitoring and management of fracture risk needs attention in the first 2 years, with a focus on NTSCI.

Articolul prezintă un mormânt de incinerație în urnă descoperit recent (2023), în timpul unui diagnostic arheologic, lângă satul Podu Rizii (com. Sălcioara, jud. Dâmbovița). Întrucât secțiunile de sondaj nu au evidențiat și alte morminte, se consideră că mormântul poate fi unul izolat. Analiza antropologică a oaselor calcinate arată că defunctul a fost un individ adult tânăr, probabil bărbat. Pa baza inventarului funerar (vârfuri de săgeți din fier, inele de buclă din bronz, fragment din psalia unei zăbale din fier) și a datării radiocarbon (au fost obținute două date 14C, prezentate detaliat), mormântul se datează în secolul al VI-lea a.Chr. Ritul funerar, ceramica și piesele de inventar funerar sunt elemente ce indică apartenența sa la grupul arheologic Ferigile. Apariția acestui mormânt în zona de câmpie, de la sud de Târgoviște, contribuie semnificativ la mobilarea periferiei sudice a grupului Ferigile.

Published: November 2024

În anul 2020, în colecțiile Muzeului de Istorie și Etnografie Sângerei au fost transmise mai multe piese arheologice descoperite de un localnic în diferite puncte din împrejurimile satului Rădoaia (r-nul Sângerei, Republica Moldova). Fibulele, în număr de 38, cele mai multe fragmentare, sunt lucrate toate din bronz, dar aparțin unor tipuri diferite. Dintre ele se remarcă o fibulă puternic profilată păstrată întreagă. Piesa se atribuie tipului Almgren 84, datat preponderent în sec. II d. Chr. Dar, spre deosebire de fibulele de tip Almgren 84 din mediul roman sau barbar și care au toate coarda exterioară prinsă într-un cârlig, exemplarul de la Rădoaia are resortul în formă de arbaletă. După toate probabilitățile, fibula de la Rădoaia constituie „o relicvă”, a cărei resort inițial s-a rupt, fiind ulterior (sec. IV d. Chr.) reparată și reutilizată. După prezentarea contextului descoperirii și descrierea piesei, sunt prezentate analogiile cele mai apropiate pentru agrafa de la Rădoaia și trecute în revistă diferitele tipuri de fibule profilate descoperite în spațiul pruto-nistrean, cu unele precizări de ordin tipologic și cronologic.
The “King Alan” Sanctuary of Old Harzhis and Epigraphic Heritage (Syunik, Republic of Armenia)
Authors:   Institute of Archaeology and Ethnography NAS Republic of Armenia  “Matenadaran” – Institute of Ancient Manuscripts after Mesrop Mashtots, Harutyunyan Arsen
Published: November 2024

The half-destroyed monument complex of the “King Alan” sanctuary, located in the rural area of Old Harzhis in the Syunik province of the Republic of Armenia, comprises a single-nave vaulted basilica church, a narthex-hall attached to the west, and a mausoleum adjoining them to the north. This complex is being comprehensively studied for the first time. Although manuscript sources do not provide evidence about the monument, more than a dozen epigraphs dating from the 11th to the 15th centuries fill this gap. The architectural and sculptural features of the monument indicate that the complex was built no later than the 10th-11th centuries. The first component of the name “King Alan” is directly connected with the term “free-born” (“ազատածին” - “azatatsin”) mentioned in the 1326 inscription on the ornamented tombstone preserved in the narthex-hall, referring to Alan, who descended from a noble family. It is logical that being “free-born” and the highly artistic tombstone led the local people to refer to Alan as a “king,” which caused the original name of the church to be forgotten and the entire complex to be known as “King Alan.” Unfortunately, this has sometimes led to misunderstandings, particularly the misinterpretation of the name Alan as a tribal name and the deceased as a king of the Alans.
Kernel Determination Problem in the Third Order 1D Moore-Gibson-Thompson Equation with Memory
Authors: A.A. Boltaev , D.K. Durdiev , A.A. Rahmonov
Published: November 2024

In this study, we address the inverse problem of determining the convolution kernel function in the third-order Moore--Gibson--Thompson (MGT) equation, which is commonly used to model fluid motion with memory effects. Specifically, we focus on the determination of the unknown kernel, which governs the memory term in the equation. Initially, we employ the Fourier spectral method to solve the direct initial-boundary-value problem for a non-homogeneous MGT equation that with the memory term. The Fourier spectral method allows us to leverage the problem's inherent linearity and spatial homogeneity, leading to an efficient and explicit construction of the solution. The direct problem is analyzed under appropriate initial and boundary conditions, which are carefully specified to ensure mathematical consistency. To solve the inverse problem, we introduce an additional condition-typically a form of observational data such as at certain points-which provides the necessary constraints for determining the kernel. We prove local existence and uniqueness theorems for solution of the problem.
The Support Behavior of the Solution to the Cauchy Problem for Higher Order Weighted Parabolic Equations
Authors: A.R. Kasaeva , A.F. Tedeev
Published: November 2024

In this paper we study the finite speed of propagation property to the Cauchy problem for weighted higher order degenerate parabolic equations. We prove that if initial data is compactly support in some fixed ball, then so does the solution for all time. Because we are considering exponentially growing weights, the size of the support should expand more slowly over time than in the non-weighted case. We prove that for a large time the support of the solution expand with logarithmic rate. That estimate of support meets with known estimate for second order parabolic equations. The main tool of the proof is based on local energy estimates on annuli which allows us to consider even nonpower character of weights. It works even in cases when the weighted Gagliardo-Nirenberg inequality does not occur. Early that approach was utilized by D. Andreucci and by author for equations in domains with noncomact boundaries and for higher order parabolic equations including the thin film equation.
К проблеме квазиособых оптимальных управлений в стохастических системах гиперболического типа
Authors: К.Б. Мансимов , Р.О. Масталиев
Published: November 2024

В предлагаемой работе исследуется задача оптимального управления стохастической системой, динамика которой описывается стохастическим дифференциальным уравнением с частными производными второго порядка гиперболического типа с краевыми условиями Гурса. Система управляется с помощью измеримых и ограниченных управлений. Рассматривается случай, когда двухпараметрический <<белый шум>> входит в правую часть управляемой системы нелинейных гиперболических уравнений второго порядка. Цель управления состоит в минимизации математического ожидания функционала качества в финальной точке области. Задачи такого вида возникают, например, при моделировании ряда процессов сушки, сорбции и других при наличии случайных воздействий типа стандартных двухпараметрических <<белых шумов>> на плоскости. Используя модифицированный вариант метода приращения, установлена формула приращения критерия качества второго порядка для функционала качества, которая позволяет получить необходимые условия оптимальности первого порядка типа линеаризованного принципа максимума Понтрягина, а также исследовать квазиособые управления (т.~е. случай вырождения условия оптимальности первого порядка), в рассматриваемой стохастической задаче. Установлены необходимые условия оптимальности первого и второго порядка. В конце, применяя специальную вариацию управления, получено поточечное необходимое условие оптимальности квазиособых управлений.
Description of Local Derivations on Jordan Algebras of Dimension Five
Authors: F.N. Arzikulov , O.O. Nuriddinov
Published: November 2024

In the present paper we investigate local derivations on finite dimensional Jordan algebras. The Gleason--Kahane--\.{Z}elazko theorem, which is a fundamental contribution in the theory of Banach algebras, asserts that every unital linear functional $F$ on a complex unital Banach algebra $A$, such that $F(a)$ belongs to the spectrum $\sigma(a)$ of $a$ for every $a\in A,$ is multiplicative. In modern terminology this is equivalent to the following condition: every unital linear local homomorphism from a unital complex Banach algebra $A$ into ${\Bbb C}$ is multiplicative. We recall that a linear map $T$ from a Banach algebra $A$ into a~Banach algebra $B$ is said to be a~local homomorphism if, for every $a$ in $A$, there exists a homomorphism $\Phi_a : A\to B$, depending on $a$, such that $T(a)=\Phi_a(a)$. A similar notion was introduced and studied to give a characterization of derivations on operator algebras. Namely, the concept of local derivations was introduced by R.~Kadison and D.~Larson, A.~Sourour independently in 1990. R.~Kadison gave the description of all continuous local derivations from a von Neumann algebra into its dual Banach bemodule. B. Jonson extends the result of R. Kadison by proving that every local derivation from a $C^*$-algebra into its Banach bimodule is a derivation. It is known that, every local derivation on a JB-algebra is a derivation. In particular, every local derivation on a finite dimensional semisimple Jordan algebra is a derivation. In the present paper we investigate derivations and local derivations on five-dimensional nilpotent non-associative Jordan algebras. The description of local derivations of nilpotent Jordan algebras is an open problem. In~the~present paper we give the description of local derivations on five-dimensional nilpotent non-associative Jordan algebras over an algebraically closed field of characteristic $\neq 2$, $3$. We also give a~criterion of a~linear operator on Jordan algebras of dimension five to be a local derivation.
EXPLORING THE IMPACT OF PARTICIPATION IN AGRICULTURAL SOCIAL MEDIA GROUPS ON TECHNICAL EFFICIENCY: A CASE STUDY FROM ORGANIC RICE FARMERS IN INDONESIA
Authors:   Brawijaya University, SYAFRIAL SYAFRIAL , RAHMAN MOH SHADIQUR ,   Brawijaya University, RETNONINGSIH DWI ,   Brawijaya University, National Pingtung University of Science and Technology, TOIBA HERY ,   Brawijaya University
Published: November 2024

This study examines the critical role of improving farming technical efficiency in agricultural development and investigates the impact of social media group participation on this efficiency. Using data from a survey of 249 organic rice farmers in Indonesia, this research employed a stochastic production frontier to estimate technical efficiency. Additionally, a two-stage predictor substitution approach was used to assess the influence of social media group participation on technical efficiency. The findings indicate that the technical efficiency of organic rice farming in the sample was approximately 64.8%, a relatively low level. The study also found a significant positive impact of social media group participation on technical efficiency. Farmers who participated in these groups demonstrated higher technical efficiency compared with those who did not. These results suggest that social media platforms have the potential to enhance agricultural practices and efficiency. The findings imply that social media groups contribute positively to farmers’ technical capabilities through information exchange, knowledge sharing, and networking.

Consumers rely on medical plants for their health benefits. Jackfruit leaves and Indian jujube leaves are commonly used in traditional remedies to address conditions such as ulcers and gout. This study was carried out to determine the phytochemical composition of Artocarpus heterophyllus and Ziziphus mauritiana leaves by conducting alkaloid and coumarin tests, pigments analysis, and phenolic compound profiling. Antioxidant activity was assessed using DPPH radical scavenging assay on extracts prepared with 50% and 100% ethanol as solvents. The colour (L* value) of each leaf showed significant variation, with the topside being considerably lighter and the underside being noticeably darker. Coumarins were present in the 50% ethanolic leave extracts. A. heterophyllus leaves extracted in 100% ethanol had the highest amount of total chlorophyll content (85.95 ± 0.24 mg/g), followed by A. heterophyllus leaves extracted in 50% ethanol (50.91 ± 0.30 mg/g), Z. mauritiana leaves extracted in 100% ethanol (42.89 ± 1.44 mg/g) and Z. mauritiana leaves extracted in 50% ethanol (18.38 ± 2.14 mg/g). Additionally, Z. mauritiana leaves contained a higher concentration of caffeic acid (1.49 mg/mL) compared with A. heterophyllus leaves (0.15 mg/mL) when
extracted with 50% ethanol. Finally, the 50% ethanolic extract of A. heterophyllus leaves exhibited higher radical scavenging activity than the 100% ethanolic leaves extract.

Chronic hyperglycemia in diabetes leads to macro and microvascular complications. An increase in the aldose reductase (ALR2) activity, accumulation of sorbitol, accumulation of advanced glycation end-products (AGEs), and inflammation lead to cellular damage, ultimately resulting in complications. ALR2 inhibition has been a consideration to treat/manage diabetic complications, but most of the ALR2 inhibitors are not free of side effects. As a part of our work to find better ALR2 inhibitors, we found that extracts of Gentiana lutea exhibited ALR2 inhibitory potential in vitro. We have also discovered the anti-atherosclerotic potential of G. lutea when supplemented its root powder (2% in the AIN-93 diet) to diabetic rats. Our very recent work suggests the reno-protective effect of G. lutea supplementation (0.2% and 2% in the AIN-93 diet). Here, we summarize our work on the role of G. lutea in preventing macrovascular complications of diabetes like atherosclerosis and microvascular complications like nephropathy and, hence, its potential as an adjunct therapy for diabetic complications.

Ensuring the safety of food products is a major challenge, with biological and chemical spoilage as a significant risk. Since synthetic antioxidants and antimicrobials have been linked to health concerns, plants, and their secondary metabolites represent a promising alternative due to their various biological activities. Therefore, the aim of this study was to examine the polyphenol content, antioxidant, antibacterial, and antibiofilm effect of a 70% ethanolic-aqueous extract of Filipendula ulmaria. Colorimetric assays revealed significant total phenolic and flavonoid content. Antioxidant assays included DPPH, where notable scavenging activity was recorded, and ferrous ion chelating ability, which appeared to be lower. In the MIC assay, the most sensitive was S. aureus MRSA, while the highest inhibition of biofilm formation was detected for S. aureus and S. aureus MRSA. Based on its noted activity, flower extract of F. ulmaria offers a promising alternative to synthetic preservatives.

One of the many products obtained after fruit processing is a wine. Black chokeberry wines were produced by innovative microvinification procedure. In this procedure, wines were produced in the absence or presence of sugar and/or enzymatic preparation glycosidase (EPG). Their chemical and biological activities were investigated. Selected phenolic compounds were identified and quantified using UPLC/MS-MS analysis. Inhibitory activity of black chokeberry wine samples against α-glucosidase was also investigated. It was shown higher content of phenolic compounds and better inhibitory activity against α-glucosidase for wines made with addition of sugar and EPG. In summary, phenolic profile and biological activity of black chokeberry wine depended from microvinification procedure which was used in the production.

Although the use of flaxseed oil that is rich with essential nutrients, has been associated with health benefits, robust scientific evidence supporting its efficacy is currently lacking. In this study, we evaluated the impact of chronic intragastric treatment of commercially available flaxseed oil by assessing several parameters of oxidative stress including pro/antioxidant balance (PAB), levels of lipid peroxidation (LPO) products and advanced oxidation protein products (AOPP) as well as activity of total superoxide dismutase (totSOD) in rat stomach. Obtained results indicate that treatment maintains the general prooxidant load and antioxidant capacity, as evidenced by the unchanged PAB levels. However, it notably elevated LPO products and AOPP levels along with totSOD activity suggesting that increased oxidative changes of lipids and proteins might be attenuated by antioxidant system.

Las arbovirosis son transmitidas a los humanos mediante artrópodos vectores; por ejemplo: dengue y chikungunya. Existe evidencia que infecciones por virus pueden modificar epigenéticamente al huésped facilitando su ciclo de vida. La identificación de tales interacciones puede proporcionar información sobre la base mecánica de las infecciones con estrategias de investigación avanzadas destinadas a abordar la actual falta de soluciones para la intervención y la terapia. El objetivo fue evaluar de manera in vitro la modulación de distintos mecanismos epigenéticos por infección de DENV y CHIKV. Se infectaron cultivos primarios de linfocitos con CHIKV y DENV. Se analizaron genes escritores, borradores y moduladores involucrados en mecanismos epigeneticos usando qPCR SYBR Green. La expresión génica se evaluó 0, 24, 48, 72, 96 y 120 hrs postinfección frente a un control. De los 4 mecanismos epigenéticos analizados; se encontraron cambios en la expresión de genes en metilación, a las 72 h postinfección se observaron la mayoría de los genes sobreexpresados, el gen DMT3B que participa en la metilación de novo y la familia de genes MBD que juegan un papel de represión transcripcional y participan en el silenciamiento génico. No se observaron cambios en la mayoría de los genes de los otros mecanismos analizados. Estos resultados sugieren que la infección viral por arbovirus activa preferencialmente el mecanismo de metilación y algunos genes específicos de otros procesos, sin embargo, se necesita mayor estudió para conocer las regiones involucradas y esclarecer una posible vía que favorezca la replicación o transcripción viral.
The Influence of psychology on sports performance: emotional and cognitive factors
Authors: Lopes Gabriel César Dias
Published: November 2024

Psychology plays a crucial role in improving sports performance, integrating emotional and cognitive factors into athletes’ preparation. This article reviews several studies on psychological skills, competitive anxiety, motivation, the impact of stress, mental imagery and attentional styles, highlighting the importance of a holistic approach that combines physical and mental training. Recent research highlights that factors such as emotional control, resilience and self-confidence are determinants of performance, while practices such as structured psychological training programs and personalized interventions contribute to consistent results. However, the lack of empirical data and case studies limits the practical application of the proposed strategies, suggesting the need for further research. The conclusion emphasizes that mental health should be a priority for both athletes and coaches, with greater emphasis on the application of psychological techniques to cope with the competitiveness and pressure associated with sport.
