Remote sensing methods are receiving more and more attention during vegetation studies, thanks to the rapid development of drones. The use of indices created using different bands of the electromagnetic spectrum is currently a common practice in agriculture e.g. normalized vegetation index (NDVI), for which, in addition to the red (R), green (G) and blue (B) bands, in different infrared (IR) ranges used bands are used. In addition, there are many indices in the literature that can only be calculated from the red, green, blue (RGB) bands and are used for different purposes. The aim of our work was to objectively compare and group the RGB indices found in the literature (37 pcs) using an objective mathematical method (structured similarity index; SSIM), as a result of which we classified the individual RGB indices into groups that give the same result. To do this, we calculated the 37 RGB indexes on a test image, and then compared the resulting images in pairs using the structural similarity index method. As a result, 28 of the 37 indexes examined could be narrowed down to 7 groups - that is, the indexes belonging to the groups are the same - while the remaining 9 indexes showed no similarity with any other index.

Resistance hypertension in hemodialysis patient usually is common and sometimes difficult to get achieved target blood pressure control. In patient with intradialytic hypertension, eye pain may occur which can be relate to the severity of the hypertension itself. Hemodialysis has relationship to Intraocular Pressure (IOP). Hemodialysis was be Increased Intraoccular Pressure (IOP) and may be the cause of eye pain during hemodialysis due to ocular dialysis disequilibrium. And this receives inadequate attention by nephrologist as a cause of intradialytic hypertension. In this article, we report a patient with resistant hypertension who complain of right eye pain during and after dialysis. After anterior chamber tapping and the aqueous humor was drained. The symptoms and hypertension improved. Undetected significant increase in IOP during hemodialysis may lead to permanent optic nerve damage and should be recognized as a cause of hypertension. An interesting point of this report was the intraocular hypertension get worsed in hemodialysis patients and could be a cause of resistance hypertension. We suggest regular ophthalmologic evaluation in ESKD (End Stage Kidney Disease) patients should be necessary especially in the patient with poorly controlled hypertension, have previous glaucoma, diabetic retinopathy, eye pain, blurred vision, conjunctivitis and headache.

A 36-year-old man without previous medical history presented to the emergency department with abdominal pain and vomiting of acute onset. His vital signs were stable and he had no fever. Abdominal exploration revealed distention with pain at palpation. Laboratory tests were normal. Abdominal X-Ray showed gastric and small intestine distention. A nasogastric tube was placed and fluid therapy started. Computed tomography showed an intestinal malrotation, without the duodenum crossing the midline and with the colic frame arranged in the left hemiabdomen (Figure 1), complicated with a midgut volvulus as demonstrated by the whirlpool sign (Figure 2, arrow).

Objective: To investigate the mechanism of MCP-1 and TGF-β regulation by TAK242 in COPD rats. Methods: Thirty-six SD rats were randomly divided into normal, COPD control, and TAK242 groups. The normal group was freely fed, and the other groups used the method of fumigation plus lipopolysaccharide tracheal drip to establish an experimental animal model of COPD. After successful modeling, each experimental group received 0.9% NaCl solution and corresponding drugs by intraperitoneal injection for 7 d. After drug administration, lung function was examined; pathological changes in lung tissue were observed by light microscopy with hematoxylin-eosin staining; mRNA expression of MCP-1 and TGF-β was detected by q-PCR; and protein expression of MCP-1 and TGF-β in lung tissue was detected by Western blot and IHC, TGF-β protein expression in rat lung tissue. Results: Compared with the normal group, rats in the COPD control group showed signs and symptoms of COPD, decreased lung function, and increased expression of MCP-1 and TGF-β. The TAK242 group showed decreased expression of MCP-1 and TGF-β compared to the COPD control group. Conclusion: MCP-1, and TGF-β played a crucial role in the early stage of COPD fibrosis. TAK242 could ameliorate airway inflammation and inhibit the progression of COPD lung fibrosis in pre-existing rats in COPD model rats.

Uterine torsion is a rare life-threatening event that happens at any age or any gestational age. By definition, it consists of a rotation of more than 45 degrees around the long axis of the uterus. The reported cases have variable presentations. The uterine torsion can happen without any sequelae either for the fetus or the mother. However, fetal and maternal mortalities were also reported in such a case. We hereby, report the case of a 29-year-old female patient, with previous four Normal Vaginal Deliveries, pregnant with twins, presenting at 36 weeks gestation with an irreducible uterine torsion at the third trimester of her pregnancy complicated by maternal and fetal deaths. We concluded that the prognosis is improved as long as the management is done rapidly. More data is needed to know about the genetic predilection and the characteristics of imaging workup for a rapid preoperative diagnosis of this condition. 

Humanity has destroyed 70% of the land by arable land, reservoirs, asphalt, concrete, garbage and ore landfills. Each of us sends 400-500 kg of garbage to the landfill per year. If from the garbage that the inhabitants of Russia throw out in a year, they built a tower with an area of ​​one meter by one meter, then it would be possible to get to the Moon through it: https://greenpeace.ru/wp-content/uploads/2019/10/report-RUSSIA -GARBAGE.pdf The area of ​​the world’s landfill on land is the size of Mexico, and it is growing.

Background: Contrast-induced acute kidney injury (CI-AKI) is an important cause of increasing the hospital stay and in-hospital mortality. By increasing intra-renal vasoconstriction, left ventricular ejection fraction (LVEF) can increase the risk of CI-AKI. We sought to investigate whether LVEF can impact the incidence of CI-AKI after cardiac catheterization and whether it can be used to predict CI-AKI. Methods: Patients underwent cardiac catheterization from December 2017 to February 2018 at Jersey Shore University Medical Center were enrolled in the study. Contrast-induced acute kidney injury (CI-AKI) was defined as an increase in serum creatinine of ≥ 0.5 mg/dL or an increase of ≥ 25% from the pre-procedure value within 72 hours post-procedure. The maximum allowable contrast dose was calculated using the following formula: (5* (weight (kg)/creatinine level (mg/dL)). A multivariable logistic regression analyses, controlling for potential confounders, were used to test associations between LVEF and CI-AKI. Results: 9.6% had post catheterization CI-AKI. A total of 18 out of 44 (44%) of patients who had CI-AKI also had ongoing congestive heart failure. No statistically significant association found neither with maximum allowable contrast (p = 0.009) nor ejection fraction (p = 0.099) with the development of CI-AKI. Conclusion: In spite of the fact that no statistically significant relationship found between the percentage maximum contrast dose and the ejection fraction with the post-procedure CI-AKI, we heighten the essential of employing Maximum Allowable Contrast Dose (MACD) and ejection fraction in patients undergoing PCI to be used as a clinical guide to predict CI-AKI.

The SARS-CoV-2 (COVID-19) pandemic outbreak has led to some lockdowns and changed human mobility and lifestyle in this country. Mashhad, one of the most polluted cities in Iran has experienced critical air pollution conditions in recent years. In the present study, the potential relationships between air quality conditions (such as popular index and criteria air pollutant concentration) and COVID-19 cases and deaths were investigated in Mashhad, Iran. To do that, the Long Short-Term Memory (LSTM) based hybrid deep learning architecture was implemented on AQI, meteorological data (such as temperature, sea level pressure, dew points, and wind speed), traffic index and impact number of death, and active cases COVID-19 from March 2019 to March 2022 in Mashhad. The results reveal the LSTM model could predict the AQI accurately. The lower error between the real and predicted AQI, including MSE, MSLE, and MAE is 0.0153, 0.0058, and 0.1043, respectively. Also, the cosine similarity between predicted AQI and real amounts of it is 1. Moreover, in the first peak of the pandemic (Aug 2021), we have the minimum amount of AQI. Meanwhile, by increasing the number of active cases and death and by starting lockdown, because the traffic is decreased, the air quality is good and the amount of AQI related to PM2.5 is 54.68. Furthermore, the decrease the active cases and death in pandemic causes a significant increase in AQI, which is 123.52 in Nov 2021, due to a decline in lockdowns, resumption of human activities, and probable temperature inversions. 

Ependymomas, which account for 10% of pediatric central nervous system (CNS) tumors, arise from the ependymal cells that line the cerebral ventricles and the central canal of the spinal cord. Extraneural metastasis to lung is rare for ependymomas primary tumors. Repeated surgeries that disrupt the blood-brain barrier may contribute to haematogenous spread, but the mechanism remains unclear. We present a case of ependymoma with extraneural metastasis to lung in a child and discuss reported cases of extracranial metastatic ependymoma with this presentation.

We report the radio-clinical observation of a 21-year-old patient, referred for anterior chest parietal discomfort evolving for 3 months ago, with the notion of trauma. The chest CT (computed tomography) scan detected a costal cartilage fracture without associated traumatic pulmonary or mediastinal changes. This case illustrates the usefulness of imaging in the diagnosis and management of costal cartilage fractures, and for screening out differential diagnoses. The aim of this study is to determine the interest of imaging in the study of fractures of the chrondro-costal cartilage. Is to determine the CT value in chrondro-costal cartilage fracture.
