Recognition and Determination of Related Traits Importance with Seed Yield in Chickpea (Cicer Aietinum)
To study the relationship between seed yield and its components 5 varieties and 18 different genotypes of Cicer arietinum were evaluated. This study was carried out under dryland farming during 2007 in research farm of Razi university. Path analysis showed that in the first level of yield, the highest direct effect was related to biological yield and the highest indirect effect was related to seed number per plant due to biological yield. In second level of yield due to the seed number per plant double seed pod number had the highest direct effect and the highest indirect effect was related to hundreds seed weight due to double the seed pod number. In second level of yield due to biological yield, the highest direct effect was related to high plant and the highest indirect effect was related to high plant due to second branch number. In the third level of yield due to a hundred seed weight, the highest direct effect was related to pod diameter and the highest indirect effect was related to pod length due to pod diameter. Factor analysis showed that 5 factors explained 81.65 percent of the variance. Cluster analysis based on ward method were arranged genotypes in 3 clusters
Comparison of the Safety and Immunogenicity of FAKHRAVAC and BBIBP-CorV Vaccines when Administrated as Booster Dose: A Parallel Two Arms, Randomized, Double Blind Clinical Trial
Purpose: This study was completed to assess the immunogenicity and safety of the FAKHRAVAC and BBIBP-CorV vaccines as a booster dose in the population with a history of receiving two doses of BBIBP-CorV vaccine. Methods: In this double-blind, parallel clinical trial, we randomly assigned healthy adults with a history of receiving two doses of the BBIBP-CorV vaccine, who then received either the FAKHRAVAC or BBIBP-CorV vaccine as a booster dose. The trial is registered in the Iranian Registry of Clinical Trial document depository (Code: IRCT20210206050259N4). Results: The outcomes that were monitored in this study were serum neutralizing antibody (Nab) activity, immunoglobulin G (IgG) level, local and systemic adverse reactions, serious adverse events, suspected unexpected serious adverse reactions, and medically attended adverse events. After administering vaccines to 435 participants, the most frequent local and systemic adverse reactions were tenderness and nausea in 23.7% and 1.4% of cases, respectively. All adverse events were mild, occurred at a similar incidence in the two groups, and were resolved within a few days. Conclusions: On the 14th day after the booster dose injection, the seroconversion rate (i.e., four-fold increase) of Nabs for seronegative participants were 87% and 84.6% in the FAKHRAVAC® and BBIBP-CorV groups, respectively. This study shows that the FAKHRAVAC® vaccine, as a booster dose, has a similar function to the BBIBP-CorV vaccine in terms of increasing the titer of virus-neutralizing antibodies, the amount of specific antibodies, and safety
Investigating the Quality of Life in Patients with Tuberculosis: A Study in Southwest Iran
Introduction: Tuberculosis is one of the most common diseases of the present era, which affects the quality of life of patients. The present study was conducted with the aim of investigating the quality of life of patients with pulmonary tuberculosis referred to health centers in Ahvaz city. Methods: The current research is a cross-sectional study that was conducted on 75 patients with tuberculosis who referred to the health centers of Ahvaz city in 2021 through a simple random sampling method of patients with tuberculosis. Data collection tools include: demographic variables checklist and sf-36 standard questionnaire (Survey short-form 36-item health) which was collected in person. After completing the sampling, the data were analyzed using SPSS version 21 statistical software and descriptive and inferential statistical tests using independent t-tests, analysis of variance and chi-square. Results: The lowest average score was related to limited physical activity followed by psychological problems and social functioning. Also, independent t-test results showed that the average scores of quality of life in men and women, pulmonary and non-pulmonary tuberculosis patients, and the patient's place of residence are statistically and significantly different. Conclusion: According to the results, tuberculosis and its treatment affect the social performance, psychological and emotional aspects of the patients' quality of life
Safety and immunogenicity of an inactivated SARS-CoV-2 vaccine (FAKHRAVAC®) in healthy adults aged 18–55 years: Randomized, double-blind, placebo-controlled, phase I clinical trial
Background: The FAKHRAVAC®, an inactivated SARS-CoV-2 vaccine, was assessed for safety and immunogenicity. Methods and findings: In this double-blind, placebo-controlled, phase I trial, we randomly assigned 135 healthy adults between 18 and 55 to receive vaccine strengths of 5 or 10 μg/dose or placebo (adjuvant only) in 0–14 or 0–21 schedules. This trial was conducted in a single center in a community setting. The safety outcomes in this study were reactogenicity, local and systemic adverse reactions, abnormal laboratory findings, and Medically Attended Adverse Events (MAAE). Immunogenicity outcomes include serum neutralizing antibody activity and specific IgG antibody levels.The most frequent local adverse reaction was tenderness (28.9%), and the most frequent systemic adverse reaction was headache (9.6%). All adverse reactions were mild, occurred at a similar incidence in all six groups, and were resolved within a few days. In the 10-µg/dose vaccine group, the geometric mean ratio for neutralizing antibody titers at two weeks after the second injection compared to the placebo group was 9.03 (95% CI: 3.89–20.95) in the 0–14 schedule and 11.77 (95% CI: 2.77–49.94) in the 0–21 schedule. The corresponding figures for the 5-µg/dose group were 2.74 (1.2–6.28) and 5.2 (1.63–16.55). The highest seroconversion rate (four-fold increase) was related to the 10-µg/dose group (71% and 67% in the 0–14 and 0–21 schedules, respectively). Conclusions: FAKHRAVAC® is safe and induces a strong humoral immune response to the SARS-CoV-2 virus at 10-µg/dose vaccine strength in adults aged 18–55. This vaccine strength was used for further assessment in the phase II trial.Trial registrationThis study is registered with https://www.irct.ir; IRCT20210206050259N1
Development of Inactivated FAKHRAVAC® Vaccine against SARS-CoV-2 Virus: Preclinical Study in Animal Models
The recent viral infection disease pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has resulted in a global public health crisis. Iran, as one of the countries that reported over five million infected cases by September 2021, has been concerned with the urgent development of effective vaccines against SARS-CoV-2. In this paper, we report the results of a study on potency and safety of an inactivated SARS-CoV-2 vaccine candidate (FAKHRAVAC) in a preclinical study so as to confirm its potential for further clinical evaluation. Here, we developed a pilot-scale production of FAKHRAVAC, a purified inactivated SARS-CoV-2 virus vaccine candidate that induces neutralizing antibodies in Balb/c mice, guinea pigs, rabbits, and non-human primates (Rhesus macaques—RM). After obtaining ethical code of IR.IUMS.REC.1399.566, immunizations of animals were conducted by using either of three different vaccine dilutions; High (H): 10 μg/dose, Medium (M): 5 μg/dose, and Low (L): 1 μg/dose, respectively. In the process of screening for viral seeds, viral strains that resulted in the most severe clinical manifestation in patients have been isolated for vaccine development. The viral seed produced the optimal immunity against SARS-CoV-2 virus, which suggests a possible broader neutralizing ability against SARS-CoV-2 strains. The seroconversion rate at the H-, M-, and L-dose groups of all tested animals reached 100% by 28 days after immunization. These data support the eligibility of FAKHRAVAC vaccine candidate for further evaluation in a clinical trial
