Abstract
Abstract
Introduction/Objective
Pancreatic ductal adenocarcinoma (PDAC) is a leading cause of cancer-related death in the United States. Determining the genetic alterations involved in the formation of PDAC and its precursor, pancreatic intraepithelial neoplasia (PanIN), may lead to earlier detection and new therapeutic options. We performed an analysis of the genetic alterations responsible for the progression of the normal pancreatic tissue to PanIN and ultimately from PanIN to PDAC.
Methods/Case Report
Initially, we used the continuous bioinformatic analysis in such a way that the RNA-seq datasets were extracted from the Biojupies database. We separately analyzed two datasets that included PDAC and PanIN, where their differentially expressed genes (DEGs) were obtained by comparison with controls. A Venn diagram was drawn to visualize the overlapping and non-overlapping DEGs in both groups. Using the Enrichr and ShinyGO databases, we examined the cell signaling pathways and ontologies of up/down-regulated genes. We mapped the protein network of important genes involved in cancer pathways by the STRING database. Finally, the shared and non-shared candidate proteins in the PDAC and PanIN pathways with the GEPIA database were confirmed in human samples.
Results (if a Case Study enter NA)
We found six shared genes in PDAC and PanIN including RAC1, RAP1A, ITGA5, RHOA, FZD2, and FN1, which appear to take part in the transition of PanIN to PDAC. Our result showed that the aforementioned genes are critical in the cell cycle, angiogenesis, and cell death processes. In the next step, the DEGs analysis in both PDAC and PanIN revealed the role of candidate genes (COX5B, NME2, MGLL, and PAICS for PanIN and PRKCA, PLCG2, NOS3, and PTK2 for PDAC) in cellular aging, MAPK, and PI3K/Akt signaling pathways.
Conclusion
Our findings showed that the overexpression of RAC1, RAP1A, ITGA5, RHOA, FZD2, and FN1 may have an important role in PanIN shifting to PDAC.

Abstract
Background: Assessing the self-efficacy beliefs of Iranian nurses in coping with occupational stressors requires to have a reliable tool. This study aims to assess the validity and reliability of the short form of Occupational Coping Self-Efficacy for Nurses (OCSE-N) Scale for Iranian nurses. Methods: This is a methodological study. Participants were 151 nurses who were randomly selected from among those working in oncology wards of hospitals affiliated to Tehran University of Medical Sciences in 2021. The nurses completed the short form of OCSE-N and the Coping Inventory for Stressful Situations- Short Form (CISS-SF). This study employed exploratory factor analysis and Confirmatory Factor Analysis (CFA) to examine the factor structure of the Persian OCSE-N. The reliability was assessed by calculating Cronbach’s alpha coefficients. The data were analyzed in AMOS and SPSS software v. 26. Results: The results of Principal Component Analysis by the Promax rotation and CFA showed that the Persian OCSE-N had two factors: 1) Coping self-efficacy to cope with the relational burden and 2) coping self-efficacy to cope with occupational burden. The correlation between subscales of OCSE-N and CISS-SF confirmed the convergent validity of the Persian OCSE-N. Cronbach’s alpha coefficients for factors 1 and 2 were reported 0.75 and 0.77, respectively. Conclusion: The Persian OCSE-N is a valid and reliable tool to measure the perceived self-efficacy in coping with stressful situations among Iranian nurses.

Abstract
Background: Low psychological resilience is an essential component in substance abuse relapse in individuals with substance use disorder. The present study aimed to investigate the effects of group schema therapy on psychological wellbeing and resilience in individuals under treatment with methadone and buprenorphine. Methods: The statistical population comprised 248 subjects with substance dependence under treatment in Samaa Addiction Treatment Clinic in Isfahan Province, Iran, in 2019. A sample of 40 patients was selected by convenience sampling method; accordingly, they were randomly allocated to the experimental and control groups. The experimental group underwent ten 90-minute weekly sessions of group schema therapy. The research instruments included the 75-item Early Maladaptive Schema Questionnaire-Short Form, the Connor-Davidson Resilience Scale, and the Ryff’s Scale of Psychological Wellbeing. Data analysis was conducted by Multivariate Analysis of Covariance (MANCOVA) using SPSS. Results: The obtained results revealed that group schema therapy was effective in promoting psychological wellbeing and resilience in individuals under treatment with methadone and buprenorphine (P<0.01). Conclusion: This study provided evidence for the effectiveness of group schema therapy in enhancing psychological wellbeing and resilience among individuals with substance dependence. This intervention program can thus be implemented by substance dependence therapists and psychiatric nurses.

Abstract
Stearoyl-ACP desaturases (SADs) and fatty acid desaturases (FADs) play a critical role in plant lipid metabolism and also affect oil fatty acid composition introducing double bonds into the hydrocarbon chains to produce unsaturated fatty acids. In the present study, the genomic sequences of three SAD and three FAD candidate genes were characterized in olive and their expression was evaluated in different plant tissues. OeSAD genes corresponded to olive SAD1 and SAD2 and to a newly identified OeSAD4, sharing the conserved protein structure with other plant species. On the other hand, the full-length genomic sequences of two microsomal OeFAD genes (FAD2-1 and FAD2-2) and the plastidial FAD6, were released. When the level of expression was tested on different tissues of cv. Leccino, OeSAD1 and OeSAD2 were mainly expressed in the fruits, while OeFAD genes showed the lowest expression in this tissue. The mRNA profiling of all genes was directly studied in fruits of Leccino and Coratina cultivars during fruit development. In both genotypes, the expression level of OeSAD1 and OeSAD2 had the highest value during and after the pit-hardening period, when oil accumulation in fruit mesocarp is intensively increasing. Furthermore, the expression level of both OeFAD2 genes, which were the main candidates for oleic acid desaturation, were almost negligible during fruit ripening. These results have made possible to define candidate genes of the machinery regulation of fatty acid composition in olive oil, providing information on their sequence, gene structure and chromosomal location.

Abstract
OBJECTIVE This study aimed to evaluate the effect of Coenzyme Q10 (CoQ10) administration to patients in the early phase of sepsis to determine its effect on the markers of inflammation and the clinical outcomes of septic patients. BACKGROUND Previous studies showed that CoQ10 levels were decreased in septic patients and worsening of mitochondrial dysfunction was observed. METHODS In this randomized controlled trial septic patients (n=40) received 100 mg CoQ10 twice a day for seven days added to standard treatment of sepsis. As a primary endpoint levels of Interleukin 6 (IL-6), Tumor Necrosis Factor-α (TNF-α), Glutathione peroxidase and malondialdehyde (MDA) were assessed at baseline, third and 7th day after the intervention. Secondary endpoints included assessment of clinical scores and in-hospital mortality. RESULTS There was no difference in baseline inflammatory and oxidative injury markers between the groups. TNF-α and MDA levels decreased significantly in the CoQ10 group on the 7th day of the study (P:0.003 for both). There was a significant difference in the in-hospital mortality in the CoQ10 group compared to the control group (P:0.01). CONCLUSION These findings suggest that CoQ10 has a positive effect on clinical parameters as well as mitochondrial dysfunction when administered in the early phase of sepsis (Tab. 2, Fig. 1, Ref. 38).

Abstract
Olive, representing one of the most important fruit crops of the Mediterranean area, is characterized by a general low fruit yield, due to numerous constraints, including alternate bearing, low flower viability, male-sterility, inter-incompatibility, and self-incompatibility (SI). Early efforts to clarify the genetic control of SI in olive gave conflicting results, and only recently, the genetic control of SI has been disclosed, revealing that olive possesses an unconventional homomorphic sporophytic diallelic system of SI, dissimilar from other described plants. This system, characterized by the presence of two SI groups, prevents self-fertilization and regulates inter-compatibility between cultivars, such that cultivars bearing the same incompatibility group are incompatible. Despite the presence of a functional SI, some varieties, in particular conditions, are able to set seeds following self-fertilization, a mechanism known as pseudo-self-compatibility (PSC), as widely reported in previous literature. Here, we summarize the results of previous works on SI in olive, particularly focusing on the occurrence of self-fertility, and offer a new perspective in view of the recent elucidation of the genetic architecture of the SI system in olive. Recent advances in research aimed at unraveling the molecular bases of SI and its breakdown in olive are also presented. The clarification of these mechanisms may have a huge impact on orchard management and will provide fundamental information for the future of olive breeding programs.

Abstract
OBJECTIVE To develop normative reference data for the Knee injury and Osteoarthritis Outcome Score (KOOS) and KOOS-Child, as well as investigate socio-demographic, psychological and physical factors associated with knee pain and disability among healthy adults. METHOD The KOOS or KOOS-Child (each containing five subscales) was administered to participants aged 8-101 years within the 1000 Norms Project, an observational study of 1000 self-reported healthy individuals. Self-efficacy, physical activity, body mass index (BMI), lower limb alignment, knee frontal plane projection angle (FPPA), knee range of motion (ROM), knee and hip strength, six-minute walk, 30-second chair stand and timed up and down stairs tests were collected. KOOS data were dichotomised using established cut-off scores and logistic regression analyses were conducted for each subscale. RESULTS Socio-demographic characteristics were similar to the Australian population. Normative reference data were generated for children (8-17 years) and adults (18-101 years). Female adults were up to twice as likely to report knee pain, symptoms and sport/recreation (Sport/Rec) limitations compared to males (P < .05). Older age, lower self-efficacy, greater BMI, varus lower limb alignment, lower knee flexion ROM and lower hip external rotation (ER) strength were independently associated with knee pain and disability among adults. CONCLUSIONS Age- and gender-stratified reference data for the KOOS and KOOS-Child have been developed to guide interpretation of results in practice and research for individuals with knee disorders. Psychological and physical factors are linked with self-reported knee pain/disability among adults, and longitudinal studies to investigate causation are required.

Abstract
The kinetic behaviour of olive tree pruning (PR), two- (2PH) and three-phase (3PH) olive pomace and their blends was investigated under combustion condition using thermogravimetric analysis. PR was blended with 2PH and 3PH at different ratios (25:75, 50:50 and 75:25) and tested in the temperature range from ambient to 1000°C in order to evaluate the co-combustion behaviour. Results showed that the thermal degradation of all samples can be divided into three regions (drying, devolatilisation, char oxidation) with different combustion properties, depending on the percentage of PR. Significant interaction was detected between the fuels, and reactivity of 2PH and 3PH was improved upon blending with PR. The iso-conversional methods, Ozawa-Flynn-Wall and Vyazovkin, were employed for the kinetic analysis of the oxidation process. The results revealed that the activation energy of PR was higher than the one of 2PH and 3PH, and the minimum value was obtained for 25PR752PH sample.

Abstract
Adenosine receptors (A1, A2a, A2b and A3) have several physiological and pathological roles in cancer cell lines. The present study was carried out to evaluate the mRNA and protein expression profile and functional role of adenosine receptors in OVCAR-3, Caov-4 and SKOV-3 ovarian cancer cell lines. The levels of mRNA and protein expression of A1, A2a, A2b and A3 adenosine receptors in the ovarian cancer cell lines were measured by Real-time PCR and western blotting. The functional roles of adenosine receptors were investigated through measurement of cAMP levels after agonist treatment. The mRNA and protein of all adenosine receptors subtypes were expressed in the ovarian cancer cell lines. Our findings demonstrated that A2b and A3 had the most mRNA and protein expression. Moreover, cAMP assay confirmed the functional role of A2b and A3 adenosine receptors. This findings demonstrated that A2b and A3 subtypes are most important adenosine receptors in humn ovarian cancer cell lines. This information provide a strong possibility into the relationship of A2b and A3 adenosine receptor and ovarian cancer.

Abstract
BACKGROUND Nitric oxide (NO) and its toxic product peroxynitrite contribute to oxidative stress and neurodegeneration in Parkinson's disease (PD). The relationship of serum levels of these oxidants with the severity of the disease [evaluated by the Unified Parkinson's Disease Rating Scale (UPDRS)] is not established. AIM This study was designed to evaluate whether patients with PD had higher NO and peroxynitrite serum level or not. PATIENTS AND METHODS Fifty eight patients with PD and 15 healthy volunteers entered this study. The concentrations of serum NO and peroxynitrite were assayed and their correlation with the UPDRS score was assessed. RESULTS Mean serum NO levels in patient group was 29.8 ± 21.631 versus 7.49 ± 2.573 in control group, which was significantly higher in patients (p ≤ 0.0001). Peroxynitrite levels in patient and control groups were 7.37±3.501 µmol/L and 3.94 ±1.389 µmol/L respectively. Patients had a significantly higher peroxynitrite level (p = 0.0004). CONCLUSIONS Higher levels of NO and peroxynitrite leads to higher UPDRS scores. It seems since current PD treatments do not affect the pathology of the disease, using drugs that exert neuroprotective properties should be considered for the treatment of PD in order to prevent further neuronal cell loss.

Abstract
BACKGROUND Osmotherapy is a cornerstone for the management of severe Traumatic Brain Injury (TBI). Hypertonic saline (HTS) has advantages as being preferred osmotic agent, but there is inadequte knowledge regarding dose and its saftey in comparison to mannitol. S100B, as a specific neuroinflammatory biomarker in TBI might be a reliable therapeutic index following osmotic therapy. AIM To compare both administration ways of HTS 5% (bolus and infusion) with mannitol upon S100B as a therapeutic tool for monitoring treatment in TBI patients. METHOD Adult patients wih modrate to severe TBI were recruited and have randomly received one of the three protocols: 125 cc of HTS 5% every 6 hrs (N: 11) as bolus; 500 cc of HTS 5% (N: 12) as infusion for 24 hrs; or 1 g/kg mannitol of 20% (N: 10) as a bolus, repeated with a dose of 0.25-0.5 g/kg every 6 hrs based on patient's response for 3 days. Serum S100B, blood pressure, serum sodium and osmolality and Glascow coma score (GCS) were measured at baseline and daily for 3 days. RESULTS Initial serum S100B level in TBI patients was higher than control group (p < 0.0001). Levels of measured S100B have decreased for all treatment groups, but reduction wasn't significantly after hyperosmolal therapy. GCS level increased significantly in infusion group (p = 0.002) and there were negative and significant correlation between serum S100B level and GCS level in some days. Mean arterial pressure increased significantly in HTS groups (bolus: p = 0.002, infusion < 0.0001). CONCLUSIONS S100B is closely related to the pathophysiological mechanism in TBI and may be useful as a therapeutic tool for treatment monitoring in TBI patients HTS is a safe and effective osmotic agent in TBI setting.

Abstract
This case report presents a coincidence of trisomy 18 and balanced Robertsonian translocation (13;14). Aneuploidy was suspected based on anomalies detected in ultrasound scan and confirmed with karyotype. In a 31 years-old healthy woman with a history of one miscarriage, second trimester ultrasound scan reported IUGR (<3rd percentile) with normal amniotic fluid, bilateral choroid plexus cysts, suspicious agenesis of corpus callosum and clenched hands. Amniocentesis was performed and karyotype was 46xx,der(13;14) (q10;q10),+18. Maternal karyotype was 45xx,der(13;14)(q10;q10). Pregnancy was continued due to legal limitation for termination after 20 weeks gestation. Delivery was done at 36 weeks gestation. A female newborn was borned and a physical feature was hypotonia, small mouth, prominent occiput, low-set and posteriorly rotated ears, clenched hands with overlapping fingers and rocker bottom feet. Ultrasound scan and echocardiography detected agenesis of corpus callosum and VSD, ASD, PDA and cardiomegaly. These features are typical of trisomy 18. Balanced Robertsonian translocation usually has no phenotypic expression. Genetic counseling and prenatal diagnosis for future pregnancy was recommended.

Abstract
BACKGROUND AND OBJECTIVE Increased oxidative stress in patients under treatment with high concentrations of oxygen (hyperoxia) is considered to be one of the major mechanisms of lung injury, which is thought among different mediators, transition metal ion, iron, by generation of very reactive free radicals which play an important role. Disruption of normal iron homeostasis has been reported in hyperoxic conditions. We hypothesized that chelation of iron can reduce hyperoxia-induced lung injury. METHODS Mechanically ventilated patients, who received oxygen with FiO2 >0.5 for at least 3 days, underwent bronchoscopy before and 72 hours after receiving "Deferasirox". Oxidative injury index and iron homeostasis markers were measured in lavage fluid and plasma. RESULTS In 12 patients, the concentrations of 8-isoprostane (p=0.005), 8-oxoguanine (p=0.04), carbonyl proteins (p=0.04)--as markers of oxidative stress--decreased significantly in lavage fluid after intervention. Levels of iron-related proteins, ferritin (p=0.04) and transferrin (p=0.005) also decreased significantly in lavage fluid. CONCLUSION Deferasirox--as an iron chelator--decrease oxidative injury index in hyperoxic condition and it could be consider safe and beneficial agent, along with other supportive measures in hyperoxia-induced lung injury for better toleration of oxygen therapy.

Abstract
OBJECTIVE Several factors including disease condition and different procedures could alter pharmacokinetic profile of drugs in critically ill patients. For optimizing patient's outcome, changing in dosing regimen is necessary. Extracorporeal Membrane Oxygenation (ECMO) is one of the procedures which could change pharmacokinetic parameters.The aim of this review was to evaluate the effect of ECMO support on pharmacokinetic parameters and subsequently pharmacotherapy. METHOD A systematic review was conducted by reviewing all papers found by searching following key words; extracorporeal membrane oxygenation, ECMO, pharmacokinetic and pharmacotherapy in bibliography database. RESULTS Different drug classes have been studied; mostly antibiotics. Almost all of the studies have been performed in neonates (as a case series). ECMO support is associated with altered pharmacokinetic parameters that may result in acute changes in plasma concentrations with potentially unpredictable pharmacological effect. Altreation in volume of distribution, protein binding, renal or hepatic clearance and sequestration of drugs by ECMO circuit may result in higher or lower doses requirement during ECMO. As yet, definite dosing guideline is not available. ECMO is extensively used recently for therapy and as a procedure affects pharmacokinetics profile along with other factors in critically ill patients. For optimizing the pharmacodynamic response and outcome of patients, drug regimen should be individualized through therapeutic drug monitoring whenever possible.

Abstract
Platanus orientalis L. (Platanaceae) is a medicinal tree used in Iranian folklore and traditional medicine as a pain and inflammation reliever. In this study, the polyphenolic and total extract of P. orientalis leaves were prepared and their antinociceptive effects were studied in mice using the acetic acid-induced writhing, formalin and light tail flick tests. Both hydroalcoholic and polyphenolic extracts of P. orientalis at a dose of 2 g/kg significantly (P<0.05) reduced acetic acid-induced abdominal writhes. These extracts were also effective in suppression of formalin-induced pain behavior but they did not show any significant analgesia in light tail flick test. It is concluded that P. orientalis extracts have moderate analgesic effect and further studies are needed to elucidate the mechanism and active constituents.

Abstract
Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy. The aim of the present study was to determine the relationship between patients reported symptoms and clinical tests with electrodiagnostic findings. Three hundred and nine patients with a mean age of 48.35 +/- 12.26 (range = 19-81 years) participated. Patients were assessed clinically and electrophysiologically. The main outcome measures were CTS related symptoms of pain and paraesthesia, Tinel sign, Phalen's test, distal sensory latency, and distal motor latency. The symptoms of presence of pain and diurnal paraesthesia showed a statistical relationship with the distal sensory latency. No relationship was found between the Tinel sign and either the distal sensory latency or the distal motor latency. Furtheremore, no relationship could be shown between Phalen 60 s, Phalen 45 s and distal sensory and motor latency. The Phalen 30 s had a significant relationship with both sensory and motor distal latency. The findings of this study indicate that both CTS related symptoms of pain, diurnal paraesthesia, and Phalen 30 s are associated with electrodiagnostic tests.

Abstract
A newly developed method for determining the frequency-dependent complex Young's modulus was employed to analyze the mechanical response of compacted microcrystalline cellulose, sorbitol, ethyl cellulose and starch for frequencies up to 20 kHz. A Debye-like relaxation was observed in all the studied pharmaceutical excipient materials and a comparison with corresponding dielectric spectroscopy data was made. The location in frequency of the relaxation peak was shown to correlate to the measured tensile strength of the tablets, and the relaxation was interpreted as the vibrational response of the interparticle hydrogen and van der Waals bindings in the tablets. Further, the measured relaxation strength, holding information about the energy loss involved in the relaxation processes, showed that the weakest material in terms of tensile strength, starch, is the material among the four tested ones that is able to absorb the most energy within its structure when exposed to external perturbations inducing vibrations in the studied frequency range. The results indicate that mechanical relaxation analysis performed over relatively broad frequency ranges should be useful for predicting material properties of importance for the functionality of a material in applications such as, e.g., drug delivery, drug storage and handling, and also for clarifying the origin of hitherto unexplained molecular processes.
