  • Morpholine and Thiomorpholine: A Privileged Scaffold Possessing Diverse
           Bioactivity Profile

    • Abstract: Morpholine and its thio analogue thiomorpholine are moieties with multifaceted roles, and demonstrated myriad physiological activity. This review discusses several analogues of morpholine and thiomorpholine synthesized by varied facile synthetic schemes resulting in substitution on multiple positions of the heterocycles. Both morpholine and its thio analogue have proven to act as bioactives against different molecular targets. These scaffolds have been an indispensable element of the pharmacophore and have exhibited selective enzyme inhibition against many receptors. They have also been an integral aspect of the drug discovery process. This review endeavours to condense the new trends concomitant to the various aspects of morpholine and thiomorpholine, their biological activities and their various synthetic routes.
       
  • A Short Review of the Work Done on Neural Networks in Oil Reservoir and
           Wells

    • Abstract: This article reviews the work done on neural networks in recent years. In recent years we have witnessed a continuous movement, from purely theoretical research to applied research, especially in the field of information processing, for problems for which there is no solution or which is not easily solved. Artificial neural networks are part of a group of dynamic systems, which, by processing experimental data, transfer the knowledge or law behind the data to the network structure. This is why these systems are called intelligent, because they learn general rules based on calculations based on numerical data or examples. These systems attempt to model the neuro-synaptic structure of the human brain. From the brain as an information processing system with a parallel and completely complex structure that makes up two percent of the body weight and consumes more than twenty percent of the body's total oxygen for reading, breathing, movement, thinking and exploring and the kidneys. Conscious actions and many unconscious behaviors are used. How the brain does these things has been around since they realized that the brain has a completely different structure for its computations than conventional computers'
       
  • Radiologic Findings of Patients with Covid-19-A Systematic Review Study

    • Abstract: < p>Background and Objective: Covid-19 is a newly emerged viral pandemic with a wide variety of systemic and local manifestations, radiography is a main diagnostic tool in patients with covid-19, the aim of the following systematic review study is to evaluate the radiologic findings of patients with covid-19 Methods: In this systematic review study, electronic search was conducted on MEDLINE, Google Scholar, Scopus, Web of knowledge and SID. The erelevant data were extracted. Results: 22 studies including 1108 patients with main age of 50.1 ± 16.2 were included. The ost common finding was ground glass opacification (31.2%) following by consolidation (28.4%) Right lobe involvement was much higher prevalent than left lobe (29% vs 12%) and lower lobe was much higher than upper lobes (33% vs 14%). Conclusion: Chest radiography is a high valuable tool in viral infection detection and according to high prevalence of radiological manifestations, it can be used effectively to encounter this disease.
       
  • A Brief Study of a Comprehensive Meta-Analysis Study of the Birth Outcomes
           of Corona Mothers in Iran

    • Abstract: Many questions pertaining to the neonates born to the mothers affected by Covid19 have arisen, particularly with regard to the likelihood of vertical transmission of the virus, the association between the intensity of disease in mothers and severity of neonatal morbidities. The present systematic review and meta-analysis attempted to deliver the responses to such uncertainties. For statistical analysis, the Comprehensive Meta-Analysis Software was employed. Overall, 16 studies including 1192 mothers with the average age of 31 years suffering definitive diagnosis of Covid-19 and delivered successfully were assessed with respect to their clinical manifestations as well as pregnancy and neonatal outcome. The median of birth weight was 3080 gr. The pooled cesarean rate was 48.3%. Respecting neonatal outcome, neonatal respiratory distress was overall revealed in 13.1% (95%CI: 10.6% to 16.0%) and in total, 20.1% (95%CI: 17.6% to 20.3%) required NICU admission. Overall, 3.8% (95%CI: 2.6% to 5.7%) of the neonates tested positive for SARS-CoV-2 infection, while no neonatal death was reported in all the studies. The rate of vertical transmission of SARS-CoV-2 infection from mother to neonate is very low and overall outcome reported in these infants is quite favorable. Thus, encouraging immediate bonding, rooming-in and breastfeeding should be considered for all neonates born to infected mothers.
       
  • Recent Biological Applications and Chemical Synthesis of Thiohydantoins

    • Abstract: Thiohydantoins and their derivatives have attracted enormous attention from researchers worldwide. They represent an important class of compounds within pharmaceutical chemistry and exist in various pharmacologically active molecules that possess significant bioactivities and involved in therapeutic drugs. Additionally, they serve as important intermediates in organic synthesis for the preparation of biologically active compounds. Many compounds from this class were chemically synthesised and tested as potential treatments for various diseases. Herein, this review focuses on the chemical properties, synthesis, and reactions of thiohydantoins with an emphasis on their application in pharmaceutical drugs and in organic synthesis.
       
  • A Systematic Short Review in Evaluate the Complications and Outcomes of
           Acute Severe of Pediatric Anesthesia

    • Abstract: The aim of present systematic review and meta‐analysis was Evaluate the complications and outcomes of acute severe of pediatric anesthesia. Based on the challenge and importance of identifying complications, determining acute and severe complications in pediatric anesthesia and helping comprehensive planning, clinical guidelines and educational curricula, the aim of present systematic review and meta‐analysis was Evaluate the complications and outcomes of acute severe of pediatric anesthesia. For Data extraction, two reviewers blind and independently extracted data from abstract and full text of studies that included. Moreover, effect size with 95% confidence interval (CI), random effect model and REML method were calculated. The Meta analysis have been evaluated with the statistical software Stata/MP v.16. A total of 724 potentially relevant titles and abstracts were found during the electronic search. Finally, nine studies required for this systematic review. Prevalence of perioperative respiratory adverse event in pediatric anesthesia was 10% (ES, 0.10 95% CI 0.01, 0.19) among nine studies and heterogeneity found (I2=0%; P =0.96). The most common acute complications in children under anesthesia are related to airway and respiratory management.
       
  • Crisis Management in the Face of Covid-19 to Control Drug Chemistry for
           Cancer Patients in Different Countries: A Review Study

    • Abstract: The present study is a PICO review that examines crisis management strategies in the face of Covid-19. The reviewed documents were searched in Google Scholar, Sid and Mag Iran databases using the keywords management, Covid-19, control, crisis. Based on studies by many hospitals, health and care networks have planned on how to deal with and increase capacity, recruit staff, use new infrastructure, and make optimal use of resources. Accident goals and programs are also presented, especially in intensive care units, which include the establishment of an acute care surgeon, the proposed infrastructure, patient transfer, the principles of triage, convalescence, and the establishment of a full-time intensive care physician. Quality Improvement Management and Crisis Management of The Most Basic Action was to completely evacuate the hospital from the hospitalized patients and prepare the wards for the reception of Covid-19 patients and close the clinics. This strategy helped to free the beds and the ability to hospitalize patients with Covid-19 and the rapid start of treatment in patients. Countries also consider it important to follow up with families of infected people in order to break the transmission chain. The most effective prevention and control measures are to find suspicious patients and close contact, confirm patients and carriers of the virus, and block transmission through isolation, disinfection, and personal protection. Therefore, early diagnosis, isolation and treatment of patients are the basic measures to control the source of infection and reduce the rate of infection.
