Aim: In our study, we aimed to investigate anesthesia management, hemodynamic changes and complications that may ocur due to steep trendelenburg, pneumoperitoneum and sugery in RARP patients operated in A.U.T.F, and to evaluate our initial results.

Methods: Patients who underwent RARP operation with the diagnosis of prostate adenocarcinoma by the Urology Clinic at Akdeniz University Faculty of Medicine between January 2015 and February 2018 were evaluated retrospectively. Patient’s demographic data, intraoperative hemodynamic and respiratory data, postoperative transfer sites, extubation times, post-extubation blood gas values, complications and discharge times were recorded. Obtained data were analyzed with IBM SPSS® 23.0 program.

Results: We found that mean age of the 131 patients included study was 62 years, and mean BMI was 27,6 kg/m2. Also we found that 47 of patients were ASA-I, 69 of patients were ASA-II and 15 of patients were ASA-III. After general evaluation, it was seen that HR, SBP, DBP and MAP decreased significantly in intraoperative period in all patients. There was also a significant decrease in pH and increase in pCO2 in patients due to pneumoperitoneum. In our study, we found thah the most common postoperative complication was nause and vomiting, and the second common was anastomotic leakage. However, none of our patients had a permanent complication.

Conclusion: In order to manage anesthesia in RARP, it is necessary to know the physiologic effects of trendelenburg position and pneumoperitoneum on the systems and physiological changes in old age.

Introduction: Granulomatous mastitis (GM) is a rare, benign, chronic inflammatory illness of the breast. It is characterized by necrotizing granulomatous lobulitis of the breast that clinically mimics breast cancer. The aim of this study was to examine the existence of Corynebacterium strains thought to be covered in the etiology of idiopathic granulomatous mastitis.
Material and Methods: In this study, we retrospectively analyzed the results of 201 breast tru-cut biopsies carry out for diagnostic purposes in the Department of General Surgery. The tissue samples of 41 patients with histopathologically diagnosed GM were examined by Gram staining. The existence of Corynebacterium kinds was investigated microscopically by adding appropriate medium.
Results: The mean age of 41 female patients with GM was 35. 7 years and the age range was 20-58 years. At the end of the study, Corynebacterium amycolatum was defined as the causative microorganism as a consequence of microbiologic examination of the tissue sample of one patient (2.4%).
Conclusion: We consider that Corynebacterium is not the etiologic agent of GM. Additionally studies with large case series are needed to explain the etiology.

Published: January 2024

Introduction: We aimed to present our single incision two-lobe technique, which we developed in our own clinic and performed by a single surgeon and to compare the results of this technique with the results of Gilling's 3-lobe technique, which we applied before.

Material Method: HOLEP was performed in 200 patients with medically resistant lower urinary tract symptoms (LUTS) and BPH, regardless of prostate size, between December 2018 and August 2022 in our urology clinic. All operations in the study were performed by a single surgeon who had completed the HoLEP learning curve, was well versed in endoscopic surgery, and had high experience. The classical Gilling 3-lobe method was preferred in the first hundred cases after the cases in the first fifty cases learning curve (Group 1, n=100). Due to some difficulties in the technique after the experience in the first hundred cases, the single incision two-lobe technique, which was created by referencing and modifying Scoffone's en bloc no touch technique, was used in the next hundred cases (Group 2, n=100).

Results: The average age of a total of 54 patients who underwent surgery due to a retroperitoneal mass was 53.8±10.0 years. While 15 (27.8%) of 54 patients with a retroperitoneal mass were diagnosed incidentally, 39 (72.2%) patients were diagnosed symptomatically. The final pathological outcome of all relapsed patients was liposarcoma. The average operation time was 178.7±85.4 minutes. The average length of stay of the patients was 6.2±3.1 days. Additionally, all of these patients had organ resection. In the Kaplan-Meier survival analysis, it was found that surgical margin had a statistically significant effect on average survival (p

Published: January 2024

The aim of this study was to investigate the use of three-dimensional (3D) printing technology to create a biodegradable scaffold loaded with WNT5A protein and assess its impact on chronic tibial osteomyelitis with bone defects (CTO&BD), focusing on osteoblast differentiation and angiogenesis. We extracted RNA from peripheral blood of healthy individuals and CTO&BD patients for sequencing, followed by differential expression and functional enrichment analysis. Network analysis was performed to identify core genes associated with CTO&BD and construct a protein–protein interaction network. Using Masquelet technique, we fabricated a 3D-printed biodegradable scaffold (G40T60@WNT5A) and conducted various experiments, including rheological testing, printability evaluation, Fourier-transform infrared spectroscopy, X-ray diffraction, scanning electron microscopy analysis, as well as mechanical and degradation performance assessments. In in vivo experiments, we observed the formation of induced membranes in a CTO&BD rat model implanted with the scaffold. In vitro experiments involved the assessment of scaffold toxicity on rat bone marrow mesenchymal stem cells and umbilical vein endothelial cells, as well as the influence on osteoblast differentiation and angiogenesis. Molecular biology techniques were used to analyze gene and protein expression levels. We discovered for the first time that WNT5A may play a crucial role in CTO&BD. The biodegradable scaffold prepared by 3D printing (G40T60@WNT5A) exhibited excellent biocompatibility in vitro. This scaffold significantly promoted the formation of induced membranes in CTO&BD rats and further enhanced osteoblast differentiation and angiogenesis. In conclusion, this study utilized innovative 3D printing technology to fabricate the G40T60@WNT5A scaffold, confirming its potential application in the treatment of CTO&BD, particularly in promoting osteoblast differentiation and angiogenesis. This research provides new methods and theoretical support for the treatment of bone defects.

Published: January 2024

Desa Purwobinangun merupakan daerah kabupaten Sleman Yogyakarta yang  berada di kawasan lereng gunung Merapi yang memiliki potensi alam yang sangat baik. Masyarakat sekitar memanfaatkan potensi alam sebagai sebuah keunggulan untuk menjadikan sektor peternakan khususnya sapi perah sebagai salah satu sektor strategis. Jumlah peternak sapi perah di wilayah ini mencapai 70 ekor yang terbagi dalam 15 kelompok ternak. Setiap harinya 100-200 liter susu sapi dihasilkan dari masing-masing peternak. Potensi hasil susu desa ini lebih banyak dibandingkan  dengan hasil peternak sapi perah di wilayah Sleman lainnya yang hanya memproduksi susu 70-100 liter/hari. Namun para peternak setempat karena keterbatasan pengetahuan dan pengalaman belum mampu mengelola hasil panen dengan optimal.  Harga jual susu dijual sangat murah karena tidak ada nilai tambah pada produk tersebut. Stadarisasi operasional juga masih terbatas sehingga kualitas produk masih cukup rendah. Melalui pemberdayaan dan implementasi teknologi pengolahan dan tata kelola manajemen bisnis yang akan dilakukan diharapkan mampu mengoptimalkan usaha ternak yang pada akhirnya akan menjadi produk unggulan daerah Sleman sekaligus mampu meningkatkan taraf hidup masyarakat setempat. Tujuan pemberdayaan ini, yaitu (1) membentuk/mengembangkan sekelompok masyarakat yang mandiri secara ekonomi dan sosial melalui pengembangkan produk olahan susu sapi perah dan tata keloala bisnis yang tepat; (2) membantu menciptakan ketenteraman dan kenyamanan dalam kehidupan bermasyarakat; (3) meningkatkan keterampilan berpikir, membaca dan menulis atau keterampilan lain yang dibutuhkan (softskill dan hardskill). Luaran yang ditargetkan dari pengabdian ini yaitu (1) peningkatan level keberdayaan mitra secara kuantitatif dan kualitatif sesuai permasalahan yang dihadapi; (2) satu artikel ilmiah yang dipublikasikan melalui Jurnal Ber-ISSN atau prosiding ber-ISBN dari seminar nasional; (3) satu artikel publikasi pada media massa cetak/elektronik; (4) video kegiatan.

Authors: Chebel Nassima , Nettour Djamel , Chettibi Mohamed , Chaib Rachid , Khoshdast Hamid , Hassanzadeh Ahmad
Published: January 2024

Demand for iron ore worldwide has been steadily increasing which leads to the extraction of iron ore deposits with more complex mineralogies and higher levels of silicon and phosphorus impurities. This is the case in Algeria with the iron ore deposit of Gara Djebilet, Tindouf; where it has recently been exploited to ensure the sufficiency of iron ore required to produce iron and steel products. This deposit has remained unexploited for several decades due to inadequate knowledge of its mineralogy, treatment, and economic assessments.
The aim of this study is to find out the microstructure, chemical composition, and mineralogical distribution of valuable minerals and impurities, to understand the efficient processing methods for this specific iron ore. The characterization of representative ironstone samples taken from the studied area was carried out using optical microscopy, X-ray fluorescence spectrometer (XRF), petrographic microscope, X-ray diffractometer (XRD), and scanning electron microscope (SEM) coupled with energy dispersive X-ray spectroscopy (EDS).
The results of the mineralogical analyses confirmed that it is an oolitic fine-grained ore consisting of gangue minerals principally composed of quartz, apatite, and iron-rich concentric cored structures. Chemical analyses of the ore indicate that it contains 56.58 wt% Fe with 7.98 wt% SiO2, 7.09 wt% Al2O3, and minor amounts of P2O5, CaO, MgO, and TiO2 compounds. The phosphorus associated was present in both ooids and groundmass, indicating that the ore has a complex texture with very rich and diverse mineralogy. For that, two potential scenarios were proposed for processing of the studied iron ore.

Published: January 2024

Angiotensin-I-converting enzyme inhibitory peptides were isolated from Cassia obtusifolia seeds by alcalase hydrolysis. Using ultrafiltration, the peptides were divided into four fractions (<1, 1–3, 3–5, >5 kDa). The fraction below 1 kDa exhibited the appropriate ACE inhibition (IC50 = 65.88 μg/mL), and was further purified by gel filtration chromatography, which displayed better angiotensin-I-converting enzyme inhibitory activity (IC50 = 53.67 μg/mL). The amino acid sequences of three novel angiotensin-I-converting enzyme inhibitory peptides were identified by liquid chromatography with tandem mass spectrometry as follows: IFPGCAN (IC50 = 23.71 μM), TEDFLTQ (IC50 = 32.82 μM), and GDEGSGGIIR (IC50 = 18.21 μM). Further experiments demonstrated that IFPGCAN and TEDFLTQ were competitive inhibitors, while GDEGSGGIIR was a noncompetitive inhibitor of the angiotensin-I-converting enzyme. Three peptides could form hydrogen bonds with the active site of the angiotensin-I-converting enzyme, according to molecular docking simulations of their interaction with the angiotensin-I-converting enzyme.

Published: January 2024

This study aimed to explore the changes in blood lipids and nutritional indexes in acute myeloid leukemia patients before and after enteral nutritional support combined with induction therapy and assess the influences of blood lipids on prognosis. The clinical data from 210 patients with initial treatment results were retrospectively analyzed. Total cholesterol, high-density lipoprotein cholesterol, and low-density lipoprotein cholesterol are lower in acute myeloid leukemia patients compared to normal controls, while triglyceride levels are higher. Total cholesterol and low-density lipoprotein cholesterol levels in M2 were elevated compared to M4 and M5, and the triglyceride level in M1 was higher than M2 and M4 before therapy. High-density lipoprotein cholesterol in M2 was higher than in M1 and M5, and low-density lipoprotein cholesterol in M1 was higher than in M5. After enteral nutritional support combined with induction therapy, total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, and nutritional status were increased. Patients with total cholesterol ≥4.8 mmol/L after therapy had a longer overall survival. The dyslipidemia and nutritional status in newly diagnosed acute myeloid leukemia patients can be partially reversed after enteral nutritional support combined with the first induction therapy, and the rebound in total cholesterol level may reflect the longer overall survival in acute myeloid leukemia patients.

One of the methods used to extinguish fires is water bombing, which is spraying water from the air using planes or helicopters. The purpose of this study is to analyze the effectiveness and efficiency of the water bombing method in dealing with land and peat forest fires in Indonesia. This study uses secondary data from various sources, such as government reports, research institutions, mass media, and non-governmental organizations. The data is then analyzed using descriptive, comparative, and evaluative methods. The results of the study show that the water bombing method has some advantages, such as fast, flexible, and able to reach areas that are difficult to access. However, this method also has some disadvantages, such as expensive, risky, and less effective in extinguishing fire in the peat soil. Therefore, this study recommends that the water bombing method should be used as one part of a comprehensive fire control strategy, which involves prevention, detection, and recovery. This study also suggests the need for improved coordination, regulation, and innovation in the use of the water bombing method in Indonesia.

This study aims to determine the effect of the addition of superplasticizer in concrete mixtures on compressive strength. To achieve this goal, a laboratory study was conducted using 12 cylindrical specimens with a diameter of 150 mm and a height of 300 mm. There are three variations of superplastcizer addition and one variation of concrete without superplastcizer addition as control. The concrete cylinders were tested at 14 days. The coarse aggregate used is a combination of 2 types of aggregates, namely Banjarmasin Stone (50%) and Merak Stone (50%).From the test results, the average compressive strength of concrete without using superplasticizer was 27.10 MPa. The compressive strength of concrete using superplasticizer (mix design results) is 37.18 MPa. For concrete that uses less superplasticizer (reduced by 1% from the mix design results) results in a compressive strength of 34.06 MPa. While for concrete that uses more superplasticizer (increased by 1% from the results of the mix design) gives a compressive strength of 37.02 MPa. Concrete that uses superplasticizer has a greater compressive strength value than concrete without superplasticizer

In this study, regression analysis was used to examine the relationship between the availability of laboratory facilities and student satisfaction in the Mechanical Engineering Education program at UPR. The basic assumptions of the regression model were met, which included normality of residual distribution, homoscedasticity, and no autocorrelation. The test results showed that there was no heteroscedasticity and autocorrelation in this regression model, and the residual values had a normal distribution. In regression analysis, it is important to evaluate the significance of independent variables on the dependent variable. The test results showed that the predictor variable (availability of laboratory facilities) had a significant effect on the dependent variable (student satisfaction). An increase in laboratory facilities availability would contribute to a 1.162 increase in student satisfaction. The R-Square value of 0.637 or 63.7% indicates that 63.7% of the variation in student satisfaction can be explained by the availability of laboratory facilities, and the remaining is influenced by other variables not included in the model. This shows that the availability of laboratory facilities has a significant effect on student satisfaction. In conclusion, this study shows that the availability of laboratory facilities has a significant positive effect on student satisfaction in the Mechanical Engineering Education program at UPR. These findings can be used as input for the university to improve the availability of laboratory facilities to provide a better learning experience for students.

Published: January 2024

BACKGROUND: Choledochal cysts are rare congenital biliary tract malformations. Presentation is variable based on age at presentation and type of the cyst. Total cyst excision with biliary reconstruction is the treatment of choice.

AIM OF THE STUDY: to present our experience with the presentation and management of these rare malformations with literature review.

MATERIALS AND METHODS: A retrospective analysis of a series of seven patients managed during the period from June 2015 to July 2020 in our institution. Recorded clinical data included sex, age at presentation, mode of presentation, diagnostic modality, cyst type and histopathology, preoperative course, operative procedure, and intraoperative and postoperative complications.

RESULTS: Of the patients enrolled in the study, 5 (71.4%) were female and 2 (28.6%) were male. Age at presentation ranged from 7-36 months. Abdominal pain was the most frequent manifestation and was recorded in 6 (85.7%) patients. The diagnosis was confirmed in all patients with MRCP. Cysts were type I in all (100%) patients. Open total cyst excision with Reux-en-Y hepaticojejunostomy was the standard procedure in all patients. No significant intraoperative vascular or structural injury was recorded. Early postoperative complications were recorded in only 1 (14.3%) patient. All patients achieved good clinical outcome, and none have shown significant findings on long term follow up.

CONCLUSIONS: Choledochal cysts are rare congenital malformations with variable presentation. Total cyst excision with hepaticojujenostomy is a standard therapeutic option and is associated with an excellent outcome and decreased incidence of long term risks.

Published: January 2024

SUMMARY:

Phyllodes tumor (PT) of the breast is rare in adolescent females, particularly malignant ones. It usually occurs in middle aged and older women. Malignant phyllodes (MP) do have a recurrence and a metastatic potential, unlike benign or borderline PT. We present the case of a 16-years old female presenting with a 6- month history of a progressive enlarged left breast mass. Tumor was excised as a mass of 7 cm in maximum diameter and sent for histopathological examination. The Histopathology revealed features of malignant phyllodes tumor that were confirmed by immunohistochemistry.

Published: January 2024

This study focuses on the covalent functionalization of the carboxylated graphene oxide layers with human serum albumin for developing new nanoplatforms capable of efficient drug loading and release for antitumor therapy. Thus, new GO-HSA conjugates have been developed and their interactions with methotrexate (MTX) molecules were evidenced through FT-IR, UV-Vis and Raman spectroscopy. The cumulative in vitro release profiles of MTX drug from GO-HSA-MTX nanoplatforms were analyzed through UV-Vis spectroscopy showing a more controlled release behavior of MTX drug under acidic conditions that simulate the tumor microenvironment demonstrating the potential use of GO-HSA-MTX as antitumoral nanocarriers.

Aromatic amines are the significant compounds used as intermediates in the organic synthesis, for obtaining such as azo dyes, antioxidants, fuel additives, corrosion inhibitors, pesticides, antiseptic agents, poultry medicine, and pharmaceutical synthesis. However, the presence of aromatic amines in water, even at very low concentrations, is extremely harmful to aquatic life and human health. Pollution of natural waters by aromatic amines is a serious environmental concern. The aim of this work was to obtain new adsorbents for use in the removal of aromatic amines from aqueous solutions. Styrene-15%divinylbenzene copolymers grafted with aminophosphonate groups (code: AP-S15%DVB) and amino acid-phosphonate groups (code: AM-S15%DVB) were used for the removal of pollutants such as: aniline, 2-methyl-aniline and 4-methyl-aniline. The adsorption capacity and the adsorption kinetic using the pseudo-first order and pseudo-second order equations were examined. From a kinetic point of view, it was established that the adsorption of the studied amino derivatives on the used adsorbents took place according to the pseudo-second order model. It was found that the adsorption rate constant increased with the increase of temperature, so the speed of the adsorption process increased. The obtained results confirm that the polymer adsorbents studied can be successfully used for the removal of aromatic amino derivatives from aqueous solutions for the purpose of wastewater treatment.

This article presents a finite element study based on tests of characterizations to find the properties of the materials studied, the injection-blowing technique, chosen in this case, is characterized by the bi-axial of the material, and one benefits from the orientation of the macromolecules in the directions of use of the material. The objective of this work is to link all the mechanical and thermal parameters during the treatment of molten polymer materials subjected to high-stress rates that can lead to significant temperature increases due to viscous heating in the order of 200�C. Predicting the temperature range is essential for good temperature control and is a major factor in determining the quality of the final product. This forces us to choose an adequate law of behavior, capable of translating the mechanical evolution under the thermal effect while explaining the rheological response of the viscoelastic metal. So this process is usually accompanied by geometric defects resulting from the original residual stresses cooling speed and the process itself. In the packaging of food products, as in this case, the bottles require to have a stable filling and a certain storage capacity.
