    Abstract Background and objectives: Heavy metals pollution is one of the most important concerns in the world. Selenium is one of the most important elements for the life, but if the absorption of this element in cells increases, it acts as a toxic element.
    Materials and methods: In this study, bacterial isolates were screened and isolated from selenium-contaminated soil and water. Twenty-five out of 42 isolates were able to reduce Selenite. Also, the response surface method (RSM) was used to evaluate and optimize the biological reduction of selenite by Selena 3. Factors of bacterial inoculation percentage, time, and amount of selenium oxyanion salt concentration were studied at five levels of -α, -1, 0, +1, and +α.

    Abstract In this study, a novel method of data augmentation has been presented for the segmentation of placental histological images when the labeled data are scarce. This method generates new realizations of the placenta intervillous morphology while maintaining the general textures and orientations. As a result, a diversified artificial dataset of images is generated that can be used for training deep learning segmentation models. We have observed that on average the presented method of data augmentation led to a 42% decrease in the binary cross-entropy loss of the validation dataset compared to the common approach in the literature. Additionally, the morphology of the intervillous space is studied under the effect of the proposed image reconstruction technique, and the diversity of the artificially generated population is quantified. We have demonstrated that the proposed method results in a more accurate morphological characterization of the placental intervillous space with an average feature relative error of 6.5%, which is significantly lower than the 11.5% error observed with conventional augmentation techniques. Due to the high resemblance of the generated images to the real ones, applications of the proposed method may not be limited to placental histological images, and it is recommended that other types of tissue be investigated in future studies.

    Abstract Pediatricians use sevoflurane due to its fast action and short recovery time. However, studies have shown that repeated exposure to anesthesia can affect learning and memory. Melatonin, an indole-type neuroendocrine hormone, has significant anti-inflammatory, and neuroprotective properties. Melatonin's impact on cognitive behavior in sevoflurane-anesthetized males and females of the Wistar rats during preadolescence was examined in this research. The cognitive function was evaluated by shuttle box and morris water maze tests, while interleukin-10, Catalase (CAT), Malondialdehyde (MDA), and Tumor Necrosis Factor-α (TNF-α) were evaluated using ELISA kits. The expression levels of the apoptosis-linked proteins, Bax, Bcl-2, and caspase-3, were determined using the western blotting technique. The learning and memory latencies of the rats were more significant in the sevoflurane groups than in the control group; however, the latencies were significantly shorter in the sevoflurane and melatonin groups than in the control group. The levels of MDA, TNF-α, Bax, and caspase-3 were significantly higher in the sevoflurane groups than in the control group. We also found that the levels of CAT and Bcl-2 were significantly reduced in the sevoflurane groups compared to the control group. Increasing levels of CAT, Bcl-2, and decreasing levels of MDA, TNF-α, Bax, and caspase-3 in response to melatonin indicate a possible contribution to the recovery from the sevoflurane impairment. Melatonin shows neuroprotective effects in male and female rats with sevoflurane-induced cognitive impairment. This suggests melatonin could be a valuable treatment for learning and memory deficits resulting from repeated exposure to sevoflurane, possibly by controlling apoptosis, oxidative stress, and inflammation.

    Abstract Objective: Pes anserine bursitis is the most common cause of periarticular knee pain. The aim of the study was to evaluate the efficacy of local injection-based therapies with different materials.
    Design: The enrolled patients were randomly allocated to three groups to receive different interventions. Outcome measures included pain severity using the visual analog scale and the Western Ontario and McMaster Universities osteoarthritis index that was evaluated before the intervention, 1 and 8 wks after that.
    Results: This trial was performed on 72 participants, with male-to-female ratio of 0.14 and with a mean age of 61.49 ± 9.35 yrs. Corticosteroids in the first group, oxygen-ozone in the second group, and dextrose 20% in the third group, were injected into the pes anserine bursa under ultrasound guidance. Interaction between time and group showed a statistically significant improvement in visual analog scale and Western Ontario and McMaster Universities Arthritis Index ( P ≤ 0.05) in favor of corticosteroids and oxygen-ozone groups after 1 wk and in favor of oxygen-ozone and prolotherapy groups after 8 wks.
    Conclusions: All three treatment options are effective for patients with pes anserine bursitis. This study showed that the effects of oxygen-ozone injection and prolotherapy last longer than those of corticosteroid injection.

    Abstract In this study, a method has been developed to improve the resolution of histological human placenta images. For this purpose, a paired series of high- and low-resolution images have been collected to train a deep neural network model that can predict image residuals required to improve the resolution of the input images. A modified version of the U-net neural network model has been tailored to find the relationship between the low resolution and residual images. After training for 900 epochs on an augmented dataset of 1000 images, the relative mean squared error of 0.003 is achieved for the prediction of 320 test images. The proposed method has not only improved the contrast of the low-resolution images at the edges of cells but added critical details and textures that mimic high-resolution images of placenta villous space.

    Abstract Introduction: Plicae or synovial folds can be detected in different joints, especially around the knee. Synovial plicae pathologies are rare conditions with difficulty in diagnosis because of various symptoms overlapping with other diseases.
    Presentation of case: We reported a rare case of symptomatic hypertrophic synovial plica in the lateral side of the knee in a 12-year-old boy following a traumatic event almost two years before the surgery. The diagnosis and treatment were conducted by knee arthroscopy, and follow-up of the patients showed significant improvements with no pain or range of motion restrictions.
    Discussion: The reported case had a significantly lower age of presentations compared to most previously reported cases, and he was diagnosed with lateral knee hypertrophic plicae, while medial knee hypertrophic plicae are more commonly reported, which is considered rare findings. Contrary to previous studies of lateral plica, our case had a history of significant direct trauma, and he was not a professional athlete. Furthermore, based on evidence, hypertrophic synovial plicae are mostly asymptomatic, but in our case, there was a pain in his knee that worsened in flexion.
    Conclusion: Physicians should consider the possibility of synovial hypertrophic plicae, especially in younger patients with histories of direct traumatic events.

    Abstract Introduction and importance: Knee arthroplasties as an effective intervention is primarily performed in patients with primary osteoarthritis and rheumatoid arthritis. Risk of hip fracture may be either decreased or increased in patients with Knee arthroplasties. There is conflicting evidence in this regard. Over the years, some studies have reported the occurrence of hip fractures following this operation as a rare but severe complication. The aim of the present case series was to report diagnosis and treatment of the mentioned five cases.
    Case presentation: During a period of two years, five patients with a diagnosis of a subtrochanteric fracture and history of total knee arthroplasty who referred to hospital were selected to include in the present case series. CLINICAL DISCUSSION: the presence of RA and treatment with glucocorticoids, a reduction of BMD following knee replacement surgery, and ultimately, an increase in physical activity and movement after the arthroplasty due to the improvement of preoperational pain, may all contribute in a complex manner to the observed outcome of increased fracture risk in the hip following TKA.
    Conclusion: In summary, special care including using medications to improve BMD should be taken to minimize the risk of such an event.

    Abstract Background: Anesthesia has a number of side effects including cognitive impairment after the surgery. Postoperative cognitive impairment is commonly associated with general anesthesia.
    Objective: The aim of this study is to evaluate the effects of Marcaine (bupivacaine hydrochloride) in memory impairment among patients undergoing elective surgery.
    Materials and methods: In this study descriptive-analytical study, patients undergoing elective lower extremity or lower abdomen surgery requiring spinal anesthesia were included. Following 24 h of the surgery, standard Wechsler questionnaire was used to assess memory of the patients. Other demographic and clinical parameters such as age, gender and blood pressure, pulse rate were also recorded. The obtained data was analyzed using SPSSv18.
    Results: In this study, 105 patients where 55 (52.4%) males and 50 (47.6%) females were studied. The mean age of the subjects was 35.73 ± 10.64 years. There was a significant difference between the mean of memory scores in terms of logical memory and overall memory (P < 0.001). There was a significant relationship between the mean scores of patients' rational memory and systolic blood pressure at admission (P = 0.030). There was a significant relationship between mean associative learning scores in patients and systolic blood pressure at admission (P = 0.046) and type of surgery (P = 0.013). Furthermore, overall memory scores were significantly associated with age (P = 0.041).
    Conclusion: Based on the results of this study, it can be concluded that spinal anesthesia had a significant effect on some areas of memory. Further studies in this area can yield more reliable results.

    Abstract Background: Multiple sclerosis (MS), as an inflammatory autoimmune disease and chronic degenerative central nervous system degeneration, often occurs in early adulthood. One of the common and debilitating symptoms of this disease is fatigue, which can affect up to 80% of patients with MS. This study aimed to evaluate the effectiveness of magnetic field therapy on fatigue in patients with MS. Methods: Present study is a single-blind randomized clinical trial (RCT) that Was conducted on patients with multiple sclerosis from March 2019 to September 2021. In this study, 46 patients who met our inclusion criteria were divided into two groups randomly: magnetotherapy intervention and control group. The intervention was performed in the form of a pulsed magnetic field with a frequency of 15 Hz and an intensity of 4.5 Millie Tesla. In order to blind patients, they were unaware of the intervention or control group, and the technician in charge of the treatment and the statistician knew about it. Data were then collected and recorded using the Fatigue Severity Scale, the Patient Health Questionnaire, and the Epworth Sleepiness Scale Questionnaire. Results: Of the 46 patients studied, 22 (48%) were male and the rest of them were female [24 cases (52%)]. The mean age of men and women was 34.4±7.3 and 33.5±1.7 years, respectively. Among the intervention and control groups, 8 people took amantadine equally in each group. In the magneto-therapy intervention group, the mean severity of fatigue reduced from 4.91±0.86 to 4.27±1.10, which was significant (p=0.024). In our control group, the mean intensity of fatigue reduced from 4.83±0.83 to 4.37±0.81, which was significant statistically (p=0.028). Although, the difference between the response of the two groups to treatment was not significant (p=0.382). Conclusion: Due to the lack of significant differences in the reduction of fatigue severity, this treatment is not recommended for the treatment and management of fatigue in patients with MS.
