Abstract

Chivalry and agility that is also translated as "generosity" have been very important phenomenon in the social history of Iran and surrounding countries and is a spiritual way of life that seems to have its roots in pre-Islamic Iran. They are divided into different categories that are called as ‘caliber’ and ‘brat’ in Persian and Arabic literature, respectively. Caliber was a group that had made ethics and campaign-specific career choice and self-indulgence and brat also defined as impoverished with no money, on the other hand people who had no interest in wealth and joined that house because of poverty and social imbalance. This study relying on comparative literature of American schools that merely doesn’t see the criteria existence of affect and affected attempt to make a comparative study of these two emerging fields within the common social and ethical implications. It seems that the main reason behind the formation of each of two groups was lack of community-based justice and social harmony. The most common social and moral characteristics of the two groups are: clemency; patience in the face of adversity, courage, generosity, support for the poor; combat skills including shooting, fighting, theft and robbery. This article also refers to common moral and social characteristics and examines the reasons behind the rise of the two groups.

Abstract

Background: Rapid test and conventional ELISA are common immunological assays used for the detection of HIV infection. In this study, we evaluated the prevalence rate of   HIV infection by rapid test used for screening HIV infection and then confirmed the positive cases with ELISA and western blot tests.
Materials and Methods: In this analytical descriptive study, 1964 out of 6923 patients who were referred to the Consult Center of Behavior Diseases, West Health Center (Valfajr Clinic), Iran University of Medical Sciences were subjected to rapid test for screening HIV infection from July 2012 to September 2014.
Results: Thirty seven out of 1964(1.88%) cases were confirmed as positive by rapid HIV test. All of the positive cases confirmed by rapid test were also confirmed as positive by ELISA and western blot tests. According to the data analysis of this study, among people diagnosed as HIV positive using rapid test, 12(32.4%) cases had unsafe heterosexual contact, followed by 10 (27%) cases of IDUs with a history of prison, shared injection, and unsafe heterosexual contact.
Conclusion:  The use of rapid test as a screening test for diagnosing HIV infection and the confirmation of all the positive and suspected negative cases by the ELISA test or western blot is recommended.

Abstract

Backgrounds: Sepsis is a systemic inflammatory response syndrome triggered by an infectious agent and an important cause of admission to intensive care units (ICU), especially in immunodeficient patients. The aim of this study was to determine the spectrum of bacterial etiology and antibacterial susceptibility pattern of sepsis and urinary tract infections (UTIs) in Iranian HIV-infected patients.
Materials & Methods: This retrospective cross-sectional study was conducted on HIV/AIDS patients for a period of ten years from January 2005 to January 2015 at two major hospitals in southwestern Iran. Standard microbiological methods were used for the isolation and identification of bacteria from samples. Antimicrobial susceptibility tests were done using disk diffusion method.
Findings: Out of 228 samples collected, the frequency of culture-positive blood and urine samples was 23.2% (n = 53) and 9.6% (n=22), respectively. Among culture-positive blood samples, Staphylococcus aureus (N = 17, 32.1%) and Pseudomonas (N = 5, 9.4%) were the main etiologic agents. While among 22 culture-positive urine samples, the predominant bacteria were Enterococci (N = 7, 31.8%) and Escherichia coli (N = 5, 22.7%). Antibacterial susceptibility testing results showed that Gram-positive bacteria were mostly susceptible to vancomycin, rifampin, and co-trimoxazole; meanwhile, Gram-negative bacteria were mostly susceptible against tobramycin, amoxicillin/clavulanate, and aztreonam.
Conclusions: In summary, this study findings highlighted the emergence and spread of opportunistic infections and a high level of antibiotic resistance among HIV-infected patients; therefore, restricted infection control strategies must be pursued in these hospitals.

Abstract

Backgrounds: This study aimed to investigate the prevalence of cryptococcaemia in HIV infected patients with CD4 counts of ≤100 cells/mm3 in a tertiary care hospital.
Materials & Methods: The present cross sectional study was conducted at the Sri Guru Ram Das Institute of Health Sciences and Research, India, as a tertiary care hospital. All HIV infected patients with CD4 counts of ≤100 cells/mm3, referring to the hospital during May 2020 to May 2021 were enrolled in this study. Blood samples taken from patients were processed for wet mounting, negative staining with India ink, gram staining, fungal culture, and cryptococcal antigen (CrAg) lateral flow assay (LFA). Statistical analysis was done using SPSS software Version 20.0 (SPSS Inc. Chicago, IL, USA) by employing Chi-square and Fisher’s exact tests to compare categorical variables.
Findings: Out of 100 patients enrolled, 28 (28%) cases had CD4 counts below 50, while 72 (84.7%) patients had CD4 counts in the range of 51-100. Also, 55 patients (55%) received antiretroviral therapy (ART), and 45 (45%) cases were ART naï􀇅ve. About 56% of patients had no opportunistic infections, and 37% had pulmonary tuberculosis. Three samples were positive in LFA, showing a prevalence of 3%, while only one of the culture samples was positive for Cryptococcus species. However, low CD4 count was found to be strongly correlated with positive serum cryptococcal antigenemia.
Conclusion: The present study reveals that cryptococcal antigenemia is a health problem, and that cryptococcal antigen screening and treatment policy recommended by WHO should be performed routinely for HIV patients registered in ART centres in the current setting, especially for those who are ART naï􀇅ve and have CD4 counts of ≤100 cells/mm3.

Abstract

Aims: The present study aimed to use the WEPP model to simulate the impact of various conservation interventions on runoff and sediment yield and determine the optimum areal extent of a watershed to be treated economically.
Materials & Methods: The study watershed (located in the Shivalik region of North-West India) was divided into various hillslopes and channels. The input files required to run the WEPP model were prepared for each hillslope and channel. The WEPP model was calibrated and validated by using monitored hydrological data (2015-2019). The impact of check dams and sedimentation basins, individually and in combination, on runoff, sediment yield, and sediment delivery ratio was simulated.
Findings: The simulation results indicated that channel erosion is predominant in the watershed, and check dams are more efficient in controlling runoff and sediment yield than sedimentation basins. However, the coupled implementation of both interventions was much more effective than the individual implementation of each intervention. The simulated runoff and sediment yield decreased by 72% and 90%, respectively, with a significant reduction of about 95% in sediment delivery ratio (SDR) compared to the untreated watershed. The results further revealed that treating 66% of the watershed area with both the interventions can be considered as an optimum area that should be treated.
Conclusions: In the absence of any recommendations for implementing management interventions in the Shivalik region of India, the results of the present study would serve as guidelines for treating degraded watersheds for their rehabilitation under limited financial resources.

Abstract

Introduction
Apiculture has long played an important role in Iran’s food industry, especially in the northern and northwestern regions. A type of beehive that was popular in Azerbaijan and is introduced in this article is cylindrical woven hives. The dimensions of these hives are about 30×85cm, which, on one side, has a fixed ceramic lid with a hole for bees to pass, and at the end, it has a movable wooden lid for harvesting honey. Nowadays, many examples of painted ceramic lids representing folk culture themes survive that were mainly made in Tabriz or its surroundings. The earliest and latest known examples bear dates back to 1115/1703-4 and 1354/1935-6. In this article, with access to about 150 examples of these lids, the form and content of these works have been examined, and the images of 52 beehive covers are published. The most important questions of this research were identifying the provenance of these examples, classifying the themes of the images and inscriptions and analyzing their content. Studying these examples can help us to understand the religion, culture, and art of the Shiite people of the Tabriz region in recent centuries.
Research Background
So far, no comprehensive research has been done on ceramic beehive covers. In 1993, the Sotheby’s auction offered a collection of 100 painted beehive covers (Sotheby’s, 1993, pp. 98-113, lots 186-195) and by the end of the twentieth century, several examples were offered again. Germanidou and Konstantinidou have published a very brief paper about a painted beehive cover showing a scene of a beekeeper harvesting honey (Germanidou and Konstantinidou, 2013, pp. 249-252). On the other hand, strangely, no significant research has been done on Tabriz pottery in the Qajar and Pahlavi periods, and the present article is considered an attempt to fill this scientific gap.

Discussion
In general, the remaining examples can be classified into three groups: those with inscriptions, religious paintings and non-religious paintings. Among the examples with inscriptions, in two cases, the prayers of “Oh the One who judges needs” and “Oh the remover of calamities” are mentioned, which should be considered as prayers to seek help from God to meet the needs and repel calamities from bee products. In two cases, the prayers of “Nād ‘Ali” and “Ism-i ‘Azam” are mentioned, which can also be considered as amulets to ward off calamities, and have been popular among the Shiites. Quranic and religious themes should also be considered in connection with increasing the blessing of the product. In some examples, the verse of “Wa in yakād” can be seen that is one of the most widely used verses of the Quran among the Iranian people to ward off evil eyes. Although the reflection of Quranic verses on the beehives can emphasize the importance of honey in Islam as a healing substance, interestingly, the verses and hadiths narrated about honey are not quoted, but prayers and verses from the Quran are written that are associated with blessing of the products and repelling calamities and evil eyes. Religious paintings are generally Shiite and in a general classification include images of panja (khamsa), Doldol and shrines of Shiite Imams.
The Doldol motif, which is a combination of the iconography of Buraq (a beast said to have transported the Prophet Muhammad to heaven), and the Lion and Sun also refers to the first Shiites Imam. Among non-religious paintings, images of animals, whether in pairs or single or next to humans, are the most common. A few examples have also depicted rural scenes, wonders, hunting and etcetera.

Conclusion
Among the cases with inscriptions, prayers were considered as a means of seeking help from God to meet the needs and also as an amulet for repelling calamities from the products. Quranic verses can also be considered in connection with increasing the blessing of the product and repelling evil eye. In addition, the panja symbol was also used to ward off evil eyes and calamities. In addition to Shiite inscriptions, all identified religious paintings are related to Shiite beliefs. Religious paintings include images of Doldol, panja, and shrines of Shiite imams, including the thresholds of Kazemayn and Najaf. The images of the panja and the names of the Five People (the Prophet, his daughter, Imam Ali and his two sons) in some of the images of the shrines show the Shiite beliefs of the people of Azerbaijan. Doldol, the mule of the Prophet that was given to ‘Ali ibn Abi Talib, is a symbol of his rightful Imamate for the Shiites. Although the Doldol motif is similar to the iconography of Buraq, the depiction of a lion on its back is reminiscent of the symbol of the Lion and the Sun. Among the non-religious paintings, the most frequent are paintings of animals, which are usually depicted in hunting scenes or on both sides of the Tree of Life. In these paintings, we are faced with different degrees of abstraction, depending on the skills and imaginations of different painters, various images have been created. Finally, the study of these examples contributes to our knowledge of the religion, culture and folk art of the Shiite people of Azerbaijan in recent centuries and is a prelude to further studies on the folk arts the Qajar and Pahlavi periods.

Abstract

Objectives: Human Immunodeficiency Virus type 1 is the causative agent of Acquired Immunodeficiency syndrome “AIDS” in human and demonstration of HIV-1 genome in samples is accepted as evidence of infection. Transmission of Infection during window period in blood transfusion settings is a world wide concern. Also there is a need for a rapid, sensitive and accurate technique to detect HIV-1 infection prior to antibody appearance in patients and new borns. Material and Method: A rapid Visual DNA Chip based on RT-Nested PCR and Enzyme-Substrate detection system was developed. At first a specific RT-Nested PCR was developed and the products were confirmed in gel electrophoresis and the products were labeled with DIG (Digoxigenin). The labeled products were then hybridized with the pre-prepared chip with an anchored specific probe. After the washing procedure an antibody against DIG conjugated with alkaline phosphates enzyme was used. After the second washing procedure the BCIP/NBT substrate was used and development of color was interpreted as positive while the negative samples developed no color. Results: 35 sera samples from different stages of HIV infection (AIDS, Asymptomatic and Symptomatic Infection) as well as 20 confirmed negative sera samples were collected and checked with the developed assay. All the positive samples developed reaction while the negative samples had no reaction. Conclusion: In the current study the developed assay showed high sensitivity and specificity to detect HIV-1 infection. It seems that the viral genome could be detected prior to antibody appearance and hence the window period could be shortened. Also the assay could be used to detect infection in new borns from infected mothers, because the maternal antibody could pass the placenta and antibody based assay have false positive results. Because of the high sensitivity, the developed assay could also detect infection in very low viral load conditions.

Abstract

Objective: The global HIV epidemic continues to expand and exceeding previous predictions. An effective vaccine represents the best hope to curtail the HIV epidemic. DNA vaccines induce humoral and cellular responses and mimic live vaccines without their pathogenic potential. The importance of CD8+ CTL responses in controlling HIV and SIV viremia has led to production of a series of vaccine candidates that effectively induce these responses. It is now widely believed that an HIV vaccine strategy must stimulate both a strong humoral (antibody) as well as cell-mediated (CTL) immune response.The p24 and gp41 play many important roles in host-virus interaction and pathogenesis. These proteins are considered as attractive vaccine candidate in which their immunogenecity and immunomodulatory effects have been confirmed. Materials and Methods: In this study, a construct, pcDNA3.1Hygro- (p24-gp41), was evaluated as a DNA vaccine candidate in Balb/C mice for generation of effective cellular immune responses. For immunizing, we used dendrosome, a novel family of vehicles for transfection and therapy. IFN-γ cytokine production and total antibody were detected by ELISA. Lymphoprolifration assay was performed by MTT test. Results: ELISA and MTT assays confirmed that the cited p24-gp41 fusion gene is able to enhance immune responses in mice. Conclusion: The construct that was used in this research can be a good candidate for DNA vaccine against HIV-1, if the future complementary tests demonstrate the same trends of immunogenic responses shown in this study.

Abstract

To study the excursion of presence and evolution of chivalrous characters in Persian literature, this article is examined three stories, “Samak e Ayyar”, “Dash Akol” and “Qeidar”, in terms of similarities and differences among characters and characterizations. mentioned stories have been selected because “samak e ayyar” is the first story in which the role of knights (“Ayaran”) is bolder than kings or heroes; “Dash Akol” is the first manly (“Dash Mashti”) character in modern Persian literature and “Qeidar” is the last one. This study indicates that in all three works, the distinction between protagonist and antagonist is clearly distinguished based on chivalry characteristic nevertheless the protagonist in “Samak e Ayyar” and “Dash Akol” is similar to antagonist in terms of facial features and behavioral characteristics while the antagonist of “Qeidar” is different from protagonist in this sense. Furthermore, “Amirkhani” appends the component of belief in Islam to the constitutive elements of chivalry characteristic, however, in spite of facial features, it is fully similar to “Samak e Ayyar” in terms of organizing events toward highlighting typical characteristics of chivalrous character.

Abstract

Objective: Despite sensitive antibody based blood donor screening, infection can be transmitted during window period. Therefore sensetive methods bosed on nucleic acid tests (NATs) have been considered. The aim of this project was to design a more sensitive method for detection of PCR products and diagnosis of HIV-1/HCV co-infection accurately. Materials and Methods: After designing specific primers and probes, the Multiplex RT-PCR method was optimized and the PCR products were labeled with Digoxigenin. The PCR product was denatured under alkaline condition and was hybridized with the specific probe that had a biotin at 5' end, and then was added to streptavidin coated wells. After washing an antibody against DIG, conjugated with alkaline phosphates enzyme was used, following second washing, the substrate (ABTS) solution was added to each reaction well. Development of green color shows the positive where as no color shows negative results. Results: 35 samples were tested with the developed method including 27 positive samples, 8 confirmed negative and 4 standard panels. False negative or positive reactions were not observed. Conclusion: This method had acceptable sensitivity and specificity for detecting HCV and HIV-1 infections during window period, also the method can be quantified which can be used for the flow-up and treatment of patients. In addition to the very high sensetivity of the test, it is cost effective and takes less time to performe.

Abstract

Objective: Today, AIDS is considered as a global problem and many efforts to generate an effective vaccine against this disease have been made, but remain inconclusive. DNA vaccines are a member of the new generation of vaccines that can efficiently stimulate the immune system. However, recent findings indicate low immunogenicity for these vaccines and it is believed that these types of vaccines require strategies that could infer more immunogenicity. The employment of adjuvants could be considered as one of the most important methods involved. In this study, a DNA vaccine candidate for HIV P24-Nef is constructed and then using genetic adjuvants IL-15 and GM-CSF, cellular immune responses have been studied. Materials and Methods: In this study the gene structure of HIV P24-Nef in eukaryotic expression vector was constructed and expression vectors of IL-15 and GM-CSF were used as adjuvants. After inoculation of the candidate vaccine to BALB/c mice, cytokine patterns, lymphocytes proliferation and cytotoxicity were analyzed. Results: Our findings indicate that candidate vaccine significantly stimulated cellular immune responses. The usage of IL-15 and GM-CSF as DNA adjuvants together and separately with candidate vaccine has strengthened cellular immune responses significantly. Co-administration of DNA adjuvants significantly increased cellular immune responses when the ratio of the vaccine dose was more than the adjuvants. Conclusion: The sequences that we selected as candidate vaccine demonstrated good immunogenicity in mouse model and co-administration of IL-15 and GM-CSF DNA adjuvants increased cellular immune response to DNA vaccine construct.

Abstract
On the status of chivalric literature, there are differences of opinion in classification of the Farsi literature genres. Some have considered this literary category as a sub-group of epic literature. Some others have referred to chivalric types as novels, while another group has categorized this genre under the heading of common literature. In this article, the assumed compatibility of epic and chivalric literature has been discussed and the relation between these two genres of literature has been studied, while the most important examples of these two groups of Farsi literary texts, namely the collection of poems of the celebrated and acclaimed Iranian poet Ferdowsi, referred to as Shah-Nameh, and the chivalric literary book named “Samak-e Ayyaar” have been selected. Thereafter, the intertextual relations between two books, based on the three foundation, productive, and interpretive oriented approaches have been scrutinized and the bonds between these two exemplary chivalric and epic literary books have been detailed and elaborated. Ultimately, it is concluded that given the meaningful relation between epic and chivalric texts, each of these two genres’ texts are categorized as sub-groups to a more general genre, stated as “heroic epic literature” genre.

Abstract

Aims: This study aimed to determine the association of socio-demographic, educational, and attitudinal factors with knowledge about HIV/AIDS among young women aged 15-24 in Indonesia.
Methods: This study was a quantitative study with observational analytical and retrospective cohort study design. The data used was secondary data derived from the Individual Recode Dataset (IR File), 2017 Demographic Health Survey (IDHS). A total of 12,632 young women, aged 15 to 24 years, were involved in the study in Indonesia. This study utilized univariate, bivariate (chi-square), and multivariate (binary logistic regression) tests.
Findings: All variables were found to have a significant association with knowledge about HIV/AIDS. The most influential variable was the source of information about AIDS, comparing categories of no information versus more information (p= <0.001, aOR= 2.53, 95%CI= 2.30-2.78).
Conclusion: One way to reduce the prevalence of HIV/AIDS is by increasing comprehensive knowledge about HIV/AIDS. Therefore, it is essential to enhance knowledge about HIV/AIDS, especially among vulnerable groups such as young women residing in rural areas, with low socioeconomic status, and low levels of education. Hence, the utilization of all available information and the equitable distribution of health facilities are crucial.

Abstract

Aims: This study aimed to investigate the connection between psychosocial well-being and quality of life among individuals living with HIV/AIDS, considering the influence of the local socio-cultural context.
Instrument & Methods: This research utilized a quantitative design with a cross-sectional methodology. A total of 230 people living with HIV/AIDS selected using an accidental sampling technique were assessed. Data were collected using the Depression Anxiety Stress Scale-42 to evaluate the psychosocial status and the Quality of Life Brief Scale to measure the quality of life. The relationship between parameters was analyzed using the Chi-square test and multivariate regression analysis.
Findings: There was a notable link between levels of stress, anxiety, and depression and the quality of life among individuals living with HIV/AIDS (p<0.0001). Participants experiencing higher degrees of stress, anxiety, and depression were more likely to have a diminished quality of life. For instance, 78.7% of those with severe anxiety and moderate stress reported a low quality of life, while 84% of respondents suffering from very severe depression also indicated poor quality of life. The univariate analysis highlighted significant associations between moderate stress, very severe depression, and quality of life; however, these connections were not maintained in the multivariate analysis. On the other hand, moderate anxiety consistently showed a significant correlation with quality of life across both univariate and multivariate analyses.
Conclusion: The quality of life of individuals living with HIV/AIDS in Jambi City is significantly influenced by their psychosocial status, including levels of stress, anxiety, and depression.

Abstract

Objective: Several vaccines against HIV have been investigated but none has been approved as an effective HIV vaccine. An approach that could induce stronger immune response against the pathogen is utilizing a multi-epitopic vaccine. This strategy was used in the design of several vaccines and resulted in improved immune responses. Materials and Methods: In this study a multi-epitopic fusion peptide including parts of HIV-1 Nef and P24 as a vaccine candidate was injected into mice and immune humoral responses measured with total antibody and IgG sub-classes using ELISA. Also measurement of cellular immune responses through evaluation of spleen cells proliferation response using MTT and cytotoxicity by LDH were performed. Finally, the cytokine pattern of IFN-γ and IL-4 were also determined with ELISA. Results: The results indicate that candidate vaccine stimulated mouse splenic lymphocyte proliferation response and also induced strong cytotoxicity responses. Analysis of humoral immune response has shown that the candidate vaccine has induced specific antibody production mainly of the IgG2a sub-class. Also cytokine pattern evaluation has shown that IFN-γ secretion was dominant. Conclusion: The use of immunogen and conserved epitopes from P24 and Nef induced strong humoral and cellular immune responses and this construct could be candidate for further studies in animal models.

Abstract

Background:
HIV has at least six regulatory genes among which the Vif protein can control HIV replication. This study, as the first report, investigated the important mutations in VIF protein in sequences from Iranian patients and using immunoinformatics, conserved regions of this protein and B-Cell, T-Cell and CTL epitopes to stimulate the immune system, were determined.
Methods:
VIF sequences were obtained from NCBI GenBank, and tertiary structures, B-Cell, T-Cell and CTL epitopes were predicted by bioinformatics tools; besides, their antigenic and allergenic properties were studied.
Results:
The most prevalent mutations in Vif protein were related to S 49 P (90%), S 140 N and N 186 S (80%). Two substitutions at positions 41 and 42 were introduced which have effect on Vif binding to host factor. In addition, three regions were identified as the best epitope sequences with high potential to induce immune system and the lowest allergic properties, among which 5-32 region was suggested as the best vaccine candidate regions.
Conclusion:
This study as the first study from Iran using immunoinformatics tools to introduced a region with the high potential to induce humoral and cellular immune systems and lowest allergenic properties which can be used for further studies on HIV vaccines.

Abstract

Aims: Developing an effective vaccine against Human Immunodeficiency Virus (HIV) is necessary. The aim of this study was the immunological evaluation of HIV-1 VLP harboring MPER-V3 in BALB/c mice model.
Materials and Methods: In the present experimental research, presenting 40 female mice, which were between 6 and 8 weeks old, were used for immunization with VLP MPER-V3. The mice were divided into 8 groups and in each group, 5 mice were considered. Injections were performed three times at three weeks intervals and subcutaneously in a volume of 100μl per mouse. Two weeks after last injection, mouse blood samples were collected by retro-orbital bleeding and immune responses were evaluated in serum for levels of total IgG and splenocytes for cytokine assay, using ELISA method. The data analysis was performed, using Mann-Whitney test and one-way analysis of variance.
Findings: The level of total antibody production was very high in all groups that had VLP alone or with adjuvant immunity, having a significant difference with the control group (p<0.05). IgG1 was the predominant isotype (Th2-biased response) in groups that had VLP injections alone or with adjuvant.
Conclusion: VLPs can stimulate the humoral immune system in mice immunized with these particles alone or formulated with adjuvant. Also, the level of production of IL-5 in the presence of the vaccine candidate as VLP increased significantly.

Abstract

Aims: Nef protein has been considered as an attractive target for the development of therapeutic HIV-1 vaccine. Furthermore, strong immunological properties of heat shock proteins (HSPs) led to their use as for subunit vaccine candidates. In the current study, the generation of Hsp20-Nef fusion protein was performed in E. , and in BALB/c mice.
Materials and Methods: At first, of Hsp20-Nef recombinant protein E. BL21 and Rosetta strains by SDS-PAGE and western blotting using anti-Nef monoclonal antibody. Then, the recombinant protein was purified by a reverse staining method. Finally, its potency was evaluated to elicit antibody response against HIV-1 Nef antigen using indirect ELISA in mice.
Findings: Our data showed a clear band of ~1230bp related to Hsp20-Nef fusion on agarose gel indicating the correct gene cloning in pET28a vector. The expression of Hsp20-Nef protein was confirmed as a clear band of ~47 SDS-PAGE and western blotting. In the immunological assay, the Hsp20-Nef protein and also the Nef protein emulsified with Freund’s adjuvant significantly enhanced the level of total compared to other groups. Moreover, of Hsp20-Nef was higher than Freund’s adjuvant/Nef in protein regimens (p<0.05).
Conclusion: The Hsp20-Nef fusion protein was effectively expressed in E. and significantly induced antibody response against HIV-1 Nef antigen.

Abstract

Aims: Many inhibitors have been introduced for the treatment of HIV-1 infections; however, most of these efforts have been failed due to the presence of resistant strains. The purpose of the current study was to investigate the treatment-resistance mutations in the HIV virus integrase gene and the effect of these mutations on the structure, function, and physical and chemical properties of this enzyme using bioinformatics software.
Materials & Methods: 36 HIV-1 integrase sequences form Iranian patients were obtained from the NCBI Genbank. After determining the mutations compared to the reference sequence, its post-modification and physical and chemical properties were described. Sequences subtypes, as well as the second and third structures, and possible interactions of this enzyme with the main inhibitors of the integrase were examined.
Findings: The analysis of selected sequences indicated a number of mutations in this protein. The subtype of most of the samples was A1 and the results of the analysis of the interaction showed that the mutations in the samples had no significant effect on the interaction of inhibitors with the integrase enzyme.
Conclusion: The binding site of these inhibitors is often found in the catalytic domain of integrase enzyme, and the results of this study depicted that most mutations were located outside this region, and this may be the main reason for the failure of these mutations to affect the interaction of inhibitors and integrase enzyme. Generally, the findings of this study suggest that anti-HIV inhibitors of HIV-1 can be used as an effective way to control this disease for Iranian patients.
