Two different modeling methods have been proposed to relate the Peng-Robinson-Stryjek-Vera (PRSV)parameter, κ1, to some common thermodynamic constants, including critical temperature (Tc), critical pressure (Pc),acentric factor (ω) and molecular weight (Mw). The methods are artificial neural network (ANN) and adaptive networkbased fuzzy inference System (ANFIS). A set of 159 data points (116, 23 and 20) was used for construct training, validating and testing, respectively. The radius parameter of ANFIS was determined through genetic algorithm (GA) optimization technique. The ANN and especially ANFIS results are in a good agreement with most of the compound groups.
A proposed framework for holding intensive 3Rs workshops in laboratory animal science
Siavash Ahmadi-Noorbakhsh,Jila Sadighi,Zahra Hatami,Ehsan Shamsi Gooshki 한국실험동물학회 2022 Laboratory Animal Research Vol.38 No.1
Principles of 3Rs are the backbone of today’s animal research. Applying 3Rs in practice requires proper education and training. Although this could be achieved via long-term courses ranging from several weeks to years, in some circumstances a short-term course may be the only viable option. In this paper we define scientific and ethical objectives for running short-term 3Rs workshops. To meet these objectives, we propose a 2-day workshop curriculum and an ethical framework. The curriculum comprises theoretical and practical sessions and covers Replacement, Reduction, and Refinement strategies. The ethical framework defines the responsibilities of lecturers and attendees, and proposes the animals and facilities requirements to run the proposed workshop curriculum. The attendees will be assessed at the end of the workshop and they receive certificates for working under supervision until they are deemed competent at their intended functions. The proposed curriculum and framework are not subscriptive, instead they share the experience gained through running more than 60 laboratory animal 3Rs workshops.

Purpose: Since late 2019, the novel coronavirus disease has been a global concern, and alongside preventive strategies, including social distancing and personal hygiene, vaccination is now the primary hope for controlling the pandemic. Sputnik V is an adenovirus vector vaccine used against coronavirus disease 2019 (COVID-19) among Iranian health care providers, and there is a lack of information regarding the Adverse Events Following Immunisation (AEFI) by Sputnik V among the Iranian population. The present study aimed to evaluate AEFI by Sputnik V vaccine among Iranian population. Materials and Methods: Every member of the Islamic Republic of Iran Medical Council received their first dose of the Sputnik V vaccine in Mashhad (Iran) and was referred to receive their second dose enrolled in the present study and asked to fill an English language checklist asking about development of any AEFI following immunization with the first dose of Sputnik V vaccine. Results: A total number of 1,347 with a mean±standard deviation age of 56.2±9.6 years filled the checklist. Most of the participants were male (838 [62.2%]). The present study demonstrated that immunization with the first dose of Sputnik V results in at least one AEFI in 32.8% of the Iranian medical council members. Most of the AEFI was related to musculoskeletal symptoms, including myalgia. By considering the age of 55 years as a cut-off point, individuals younger than 55 had a higher rate of AEFI (41.3% vs. 22.5%, p=0.0001). Male gender, use of analgesics, beta-blockers, and previous COVID-19 infection have a lower chance of developing AEFI (p<0.05). Conclusion: The present study demonstrated that most of the AEFI was related to musculoskeletal symptoms, including myalgia, and older individuals, male gender and those receiving analgesics and beta-blockers were less likely to develop AEFI following immunization with the first dose of Sputnik V.
Goiter Frequency Is More Strongly Associated with Gastric Adenocarcinoma than Urine Iodine Level

Purpose: We designed our study to evaluate the hypothesis that gastric cancer is correlated with iodine deficiency or thyroid dysfunction. Materials and Methods: We investigated the total body iodine reserve, thyroid function status and autoimmune disorder in 40 recently diagnosed gastric adenocarcinoma cases versus 80 healthy controls. The participants came from a region with high gastric cancer rate but sufficient iodine supply due to salt iodination. The investigation included urine iodine level, thyroid gland clinical and ultrasonographic examination, and thyroid function tests. Results: Goiter was detected more frequently in the case group (P=0.001); such a finding, however, was not true for lower than normal urine iodine levels. The free T3 mean level was significantly lower in the case group compared to the control group (P=0.005). Conclusions: The higher prevalence of goiter rather than low levels of urinary iodine in gastric adenocarcinoma cases suggests that goiter, perhaps due to protracted but currently adjusted iodine deficiency, is more likely to be associated with gastric adenocarcinoma compared to the existing iodine deficiency itself.
