Abstract
In this research work, two new palladium complexes [trans-Pd(C15H10NOCH3)2]Cl2 (1) and [cis- Pd(C15H10NOCH3)(PPh3)2Cl]Cl (2) were synthesized using an alkoxyme ligand named isophethalaldoxime. Then structure characterization has been done by FT-IR and different NMR (1H, 13C and 31P) spectroscopy. Then, their interactions with biological macromolecules including deoxyribonucleic acid and bovine serum albumin were studied using various spectroscopic methods such as UV-Vis absorption, fluorescence emission spectroscopy and circular dichroism. The results showed the binding of the prepared complexes to the deoxyribonucleic acid via grooves and different binding sites of bovine serum albumin. Fluorescence emission data showed that the mechanism of extinction of albumin emission by these compounds is static. Competitive titration was performed on albumin with eosin-Y, ibuprofen and digoxin as site markers I, II and III. The antitumor activity and toxicity of these compounds were evaluated on cancer cell lines A549 (leukemia) and K562 by in-vitro cytotoxicity test. The IC50 values showed the good activity of these complexes in inhibiting cancer cells. In the last section, the release mechanism of synthesized complexes from albumin nanoparticles (BNPs) was investigated and theoretical calculations were performed that showed Korsmeyer-Peppas mechanism for complex (1) and Quadratic mechanism for complex (2).

Abstract
BACKGROUND In vitro maturation (IVM) and oocyte cryopreservation are therapeutic options in assisted reproductive technology which is used to preserve fertility in patients with different causes of infertility. OBJECTIVE To analyze in vitro development of vitrified-warmed oocytes in the presence of human follicular fluid (FF) and bone marrow mesenchymal stem cell-conditioned medium (BMSC-CM) as a rescue strategy in fertility preservation. MATERIALS AND METHODS BMSC-CM and FF media were used as two natural media. Not only osteogenic and adipogenic differentiation but also flow cytometry was carried out to confirm the nature of mesenchymal stem cells. A total of 327 vitrified-warmed oocytes were randomly assigned to three groups with different maturation media. After 24 h the maturation rate was evaluated. In vitro fertilization and also embryo development were also assessed. RESULTS Oocytes matured in the BMSC-CM and FF groups showed a significant increase compared to the control group (76.6+/-2.9, 53.2±1.0 , and 40.8+/-6.1, respectively) (P % 0.05). Embryo cleavage rates in the BMSC-CM were dramatically higher than FF and control groups (85.6+/-2.2, 70.5+/-2.2, and 60.7+/-1.5, respectively). Blastocyst formation rates in the BMSC-CM group were statically different compared to FF and control groups (73.6+/-1.0, 58.5+/-1.0, and 45.8+/-4.2, respectively). CONCLUSION BMSC-CM and FF media not only improve the maturation rate of vitrified warmed oocytes but also significantly increase embryo cleavage and blastocyst rates. DOI: 10.54680/fr23210110512.

Abstract
The incidence and mortality (per 100,000) rates in chest CT are highest for the lungs and breasts (incidence: lung = 116, breast = 98.64; mortality: lung = 113.43, breast = 49.72). Abdominopelvic CT scans showed the highest incidence for stomach (79.57), colon (62.86), bladder (48.69), and liver (28.63), respectively. Mortality is highest for the bladder (80.44), stomach (72.43), colon (69.02), and liver (63.78), respectively. This study helps to better understand the concept of radiation dose and the numbers reported as organ dose and effective dose and identify the probability of the stochastic effect.

Abstract
Tibial plateau fracture is a common intra-articular fracture caused by axial compression and Varus or Valgus force. This study aimed at the relationship between Luo classification morphology of tibial plateau fractures with clinical outcomes and surgical complications. The cross-sectional study was conducted on patients with Schatzker type II tibial plateau fracture who underwent surgery between May 2018 and January 2021. Clinical outcomes were measured by the AKSS, VAS, Lysholm score, alignment, and ROM. A total of 65 patients with a mean age of 36.38 years were enrolled. There was a significant difference in AKSS (p=0.001), VAS score (p=0.011), and mechanical axis alignment (p=0.037) between the groups by pre-operative joint depression depth below and above 10 millimeters. The higher pre-operative or post- operative size of joint depression depth in patients with Schatzker type II tibial plateau fractures was associated with poor outcomes, more pain, and malalignment. A higher surface area of joint depression was associated with a lower clinical outcome score and more pain.

Abstract
BACKGROUND Immature oocyte cryopreservation is a therapeutic option in assisted reproductive technology. OBJECTIVE To evaluate the effects of supplementing oocyte maturation medium with human follicular fluid (hFF), zinc and copper. MATERIALS AND METHODS Four different maturation media supplemented with 10% follicular fluid, 4 μg/mL copper and 1 μg/mL zinc were used for vitrified-warmed oocytes of mouse. RESULTS Maturation rate was the highest (63.3%) in the presence of zinc. Cleavage and blastocyst rates in groups with copper and zinc were significantly higher than the control group (39.9% and 46.4% vs. 28.8%), without any significant difference between Zn and Cu. CONCLUSION Our findings indicate the high importance of using hFF as a natural medium, and also zinc and copper as two efficient trace elements in the maturation medium for vitrified-warmed oocytes.

Abstract
Although pulmonary diseases account for a large number of deaths in the world, most have no treatment other than transplantation. New therapeutic methods for lung treatment include lung tissue engineering and regenerative medicine. Lung decellularization has been used to produce an appropriate scaffold for recellularization and implantation. We investigated 3-[(3-cholamidopropyl) dimethylammonio]-1-propanesulfonate (CHAPS) with sodium dodecyl sulfate (SDS) and Triton X-100 detergents for effecting rat lung decellularization. We evaluated using conventional histology, immunofluorescence staining and SEM methods for removing nuclear material while leaving intact extracellular matrix proteins and three-dimensional architecture. We investigated different concentrations of CHAPS, SDS and Triton X-100 for different periods. We found that 2 mM CHAPS + 0/1% SDS for 48 h was the best among the treatments investigated. Our method can be used to produce an appropriate scaffold for recellularization by stem cells and for investigations ex vivo and in vivo.

Abstract
Background: The fourth most prevalent cancer worldwide and a major cause of death in developing countries is
gastric cancer (GC). Human epidermal growth factor receptor 2 (HER2), is a proto-oncogene expressed in different
solid tumors. This study aimed to evaluate possible associations of HER2 expression status with survival rate, age,
sex, tumor grade, histopathological type, and primary tumor location in patients with GC. Methods: Subjects were
enrolled in this cohort study after consideration of inclusion and exclusion criteria. Biopsy specimens were stained using
immunohistochemistry. Samples with a score of 3+ were considered to exhibit HER2 overexpression. The mentioned
variables were extracted from patients’ files as well as by clinical evaluation. The Kaplan-Meier method was applied
for analyzing the survival rate and Chi square for possible factor associations. Results: A total of 210 patients (25.2%
female and 74.8% male) were enrolled. In a 5-year follow-up (adherence rate: 45.7%), the average survival was 9.4±10.9
months. HER2 overexpression was evident in 24%. There was no statistically significant association found between
HER2 expression and primary tumor location (p-value=0.63), histopathological type (p-value=0.72), or tumor grade
(p-value=0.051). Furthermore, no statistically significant links were apparent with tumor grade in either male or female
groups as well as patients aged ≥60 and ˂60 years (all p-values >0.05). Moreover, no statistically significant association
was detected between HER2 expression status (p-value=0.88), sex (p-value=0.31), and age (p-value=0.055) with patient
survival. Conclusions: No statistically meaningful association was found between all parameters examined and HER2
expression status. Divergence of the results from earlier studies might be due to genetic variation. Thus, performing a
meta-analysis on certain races might be helpful for clarification.

Abstract
Gamma ray source has very important role in precision of multi-phase flow metering. In this study, different combination of gamma ray sources ((133Ba-137Cs), (133Ba-60Co), (241Am-137Cs), (241Am-60Co), (133Ba-241Am) and (60Co-137Cs)) were investigated in order to optimize the three-phase flow meter. Three phases were water, oil and gas and the regime was considered annular. The required data was numerically generated using MCNP-X code which is a Monte-Carlo code. Indeed, the present study devotes to forecast the volume fractions in the annular three-phase flow, based on a multi energy metering system including various radiation sources and also one NaI detector, using a hybrid model of artificial neural network and Jaya Optimization algorithm. Since the summation of volume fractions is constant, a constraint modeling problem exists, meaning that the hybrid model must forecast only two volume fractions. Six hybrid models associated with the number of used radiation sources are designed. The models are employed to forecast the gas and water volume fractions. The next step is to train the hybrid models based on numerically obtained data. The results show that, the best forecast results are obtained for the gas and water volume fractions of the system including the (241Am-137Cs) as the radiation source.

Abstract
The problem of how to precisely measure the volume fractions of oil-gas-water mixtures in a pipeline remains as one of the main challenges in the petroleum industry. This paper reports the capability of Radial Basis Function (RBF) in forecasting the volume fractions in a gas-oil-water multiphase system. Indeed, in the present research, the volume fractions in the annular three-phase flow are measured based on a dual energy metering system including the 152Eu and 137Cs and one NaI detector, and then modeled by a RBF model. Since the summation of volume fractions are constant (equal to 100%), therefore it is enough for the RBF model to forecast only two volume fractions. In this investigation, three RBF models are employed. The first model is used to forecast the oil and water volume fractions. The next one is utilized to forecast the water and gas volume fractions, and the last one to forecast the gas and oil volume fractions. In the next stage, the numerical data obtained from MCNP-X code must be introduced to the RBF models. Then, the average errors of these three models are calculated and compared. The model which has the least error is picked up as the best predictive model. Based on the results, the best RBF model, forecasts the oil and water volume fractions with the mean relative error of less than 0.5%, which indicates that the RBF model introduced in this study ensures an effective enough mechanism to forecast the results.

Abstract
Pulmonary diseases cusecs a large portion of mortality in the world. There is no more cure for pulmonary diseases and many approaches are needed for finding ways to cure. Nowadays, implantation and drugs are only ways for curing those people who are facing with these diseases. Tissue engineering and regenerative medicine have been appeared as multidisciplinary field and also, they presents new therapeutic approaches for pulmonary diseases. One of these therapeutic approaches is decellularization which removes cellular but leaves intact important extracellular matrix (ECM) proteins and three-dimensional (3D) architecture and also, this approach has been studied for in-vitro and ex-vivo. In this study, we aimed to investigate a comparison of different concentrations of Triton X-100 and Sodium dodecyl sulfate detergents in lung decellularization in order to evaluate the effects of different concentrations and times of mentioned detergents on three dimensional and ECM proteins lung. Two detergents (Triton-X100 and Sodium dodecyl sulfat) were used with different concentrations for decellularizing rat lungs for maintaining of three-dimensional lung architecture and ECM protein compositions which have significant roles in differentiation and migration of stem cells. Results showed that SDS 0.05%, 0.1% and Triton-X100 0.1% could maintain 3D, elastin and collagen better than other concentrations in 24 and 48 h- decellularization. We concluded that these approaches can help to achieve three-dimensional architecture and extracellular matrix of lung with minimum destruction for next step such as recellularization and in-vivo study.

Abstract
Glutathione S-transferases (GST) are considered among the most controversial biomarkers of water pollutants in fish with little known about factors influencing their activities. The objective of this study was to investigate how gender, dose, ploidy, and sampling time alter hepatic GST activities in African catfish (Clarias gariepinus) following β-naphthoflavone (β-NF) injection. Newly matured male and female diploid and triploid fish were intraperitoneally (i.p.) injected with 0, 15, or 75 mg/kg of β-NF, and livers were excised 24, 48, and 72 h post-injection. Results showed that hepatic GST activities were significantly inhibited by both doses of β-NF. Inhibition was greater in females than males, but no significant differences were observed between diploid and triploid fish. Enzymatic activities differed over time with lowest levels 72 h post-injection. These results extend our understanding of GST activity in fish and highlight the necessity of considering confounding factors when comparing different studies.

Abstract
Introduction: The urinary tract infection is the most common infection and drug resistance to it is increasing. Due to the acute infection, the prescribing of medicine is conducted before culture and antibiogram and according to the results, disk diffusion is adjusted. The aim of this study was to compare it with MIC to determine to what extent the current method could be useful. Methods: This descriptive cross-sectional investigation research regarding drug resistance was conducted with the help of two methods of disk diffusion and MIC on the isolations of patients' urine culture with UTI (midstream clean catch). Bacterial resistance was measured, and sensitivity and specificity were evaluated. Results: The MIC method was considered the gold standard and, according to the related formula, the sensitivity and specificity of disk diffusion were related to 13 antibiotics obtained as it follows: ciprofloxacin 69% and 69.1% (0.0001 > p and Kappa = .292), cotrimoxazole 50% and 77.3% (p = 0.010), nitrofurantoin 84.7% and 58.2% (0.0001 > p and Kappa = 0.44), ampicilin 83.3% and 85.3% (0.0001 > p and Kappa = 0.33), ofloxacin 65.5% and 83.9% (0.0001 > p and Kappa = 0.429), cephalexin 46.2% and 75.2% (p = 0.012 and Kappa = 0.116), gentamicin 64.2% and 66% (0.0001 > p and Kappa = 0.276), ceftriaxone 27.6% and 80.9% (p = 0.216 and Kappa = 0.074), nalidixic acid 42.1% and 89.2% (0.0001 > p and Kappa = 0.354), imipenem 63.4% and 70.4% (0.0001 > p and Kappa 0.306), co-amoxiclav 83% and 71% (0.0001 > p and Kappa = 0.412), cefixime 21% and 80.9% (0.0001 > p and Kappa = 0.412), vancomycin 55.9% and 94.7 (0.9001 > p and Kappa = 0.532). Sensitivity and specificity of this method were reported to be lower than MIC. Conclusions: Due to the low sensitivity and specificity of the disk diffusion method, antibiotic therapy should be certainly considered in clinical conditions, and risk factors for the infection and only by this approach cannot prescribe the drug.

Abstract
This study was carried out to evaluate the nested PCR for specific detection of different strains of B. burgdorferi. Five strains of B. burgdorferi including ACA-1, B-31, 2B45, 3B45, 7B49 obtained from different countries were used in this study. The strains of B. hermsii, Escherichia. coli and T. pallidum were also included as control strains. Two pairs of nested PCR primers were used to amplify the gene encoding the Osp-A protein of B. burgdorfer under standard PCR condition. In a two stage procedure, nested PCR yielded a positive reaction for five tested strains of B. burgdorferi. None the strains including B. hermsii, E. coli and T. pallidum showed positive reaction when used as control strains in PCR. In conclusion, nested PCR showed acceptable specificity for rapid detection ofB. burgdorferi.

Abstract
Quantitative evaluation of polymer composition across the SEC chromatogram can provide more accurate characterization of heterogeneous polymer samples for problem solving and for material specification. To this end Fourier-transform infrared spectroscopy (FTIR) with solvent-evaporation interfaces has become a very powerful detector for size-exclusion chromatography (SEC). The solvent-evaporation interface removes the mobile phase at the exit of the chromatograph and deposits the separated molecular sizes as polymer films on infrared transparent substrates. Quantitative interpretation of the FTIR spectra obtained from these films has recently been found to be best accomplished by using partial least squares. In this paper, polystyrene and poly(methylmethacrylate), alone, as blends, and a copolymer were analyzed in a SEC equipped with an evaporative interface. Molecular weight effects, wavelength selection, the effect of averaging spectra on results, and selection of the best data preprocessing method were investigated. General methods of evaluating these variables were developed to arrive at conditions for this particular "model" situation in order to provide a basis for the analysis of more complex polymers.

Abstract
With the increasing popularity of evaporative interfaces, detection using Fourier Transform Infrared (FTIR) spectrometry in the mid-infrared region is becoming more important in size-exclusion chromatography (SEC). FTIR spectrometry is a powerful, and potentially very widely applicable, method for obtaining chemical functional group information for each molecular size fraction. Quantitative evaluation of polymer composition across the SEC chromatogram can provide more accurate characterization of heterogeneous polymer samples for problem solving and for material specification. The evaporative interface removes the SEC mobile phase at the exit of the column and deposits the eluting polymer as a continuous film stripe or as a series of discrete films on infrared transparent substrates. Initially this detection approach was used only for qualitative analysis. More recently, it is being used quantitatively. Previously we demonstrated that the quality of the film generated by the evaporative interface was critical to determining the suitability of the resulting FTIR spectra for quantitative analysis. In a continuation of this work, the objective of this paper is to develop a procedure for obtaining valid quantitative results for polymer blends with the interface. Experimental topics include improving the quality of polymer films by post-SEC treatments, off-line FTIR calibrating using other means to obtain high quality polymer films, and utilizing in-line SEC detectors in calibration. Interpretation aspects focus upon peak fitting of FTIR spectra, linear regression, partial least squares, and data pre-processing. PLS prediction with internal calibration using the second derivative of solvent-annealed film spectra was found to provide the best compromise between processing time, accuracy and precision.
