Human papillomavirus(HPV) is a viral infection that usually causes growths on mucous membranes or skin (warts). It has been confirmed that there are more than 100 types of human papilloma-virus (HPV). Some types of HPV infections cause warts, and some of them may cause different types of cancer. One of the most common ways of transmitting the HPV virus is unprotected sex, and this virus is the leading cause of cancers of the urinary and genital tracts. Cervical cancer is the fourth cause of cancer death in women, and more than 90% are associated with persistent infection by one of the most dangerous types of the virus. This research aimed to determine the genotypes of the HPV virus in DNA extracted from people suspected of being infected with HPV. In this cross-sectional epidemiological study, 225 cytology samples have been obtained from people suspected of being infected with the HPV virus, who had been referred to the Pardis laboratory of medical genetics of Dr. Abdolazim Sarli located in the Gonbad for diagnosis from 1401 to 1402. DNA extraction was done by CEDBIO kit and the determination of HPV virus genotypes was done by a GENOVA kit. The analysis of the data was done by Excel software. In this research, 225 samples have been studied. 106 women were positive while 118 women were negative. Furthermore, the most common high-risk genotypes were (16),(31,33,35,39,45,52,58,59,67) and (18) while the most common low-risk genotypes were (40,42,43,44,54,61,62,81,83,89) and (6,11). Moreover, the maximum age range of positive women is between 28 and 35. This study has demonstrated that the determining of dangerous genotypes is considered an essential measure in managing people infected with HPV, especially persistent infection and prevention of cervical cancer.

Recently, stem cells have been considered renewable cell sources in the treatment of diabetes and the development of insulin-producing cells. In this regard, the current study aimed to compare Insulin-producing cells from bone marrow stem cells with injectable insulin in rats with type I diabetes. For this purpose, 40 rats were divided into four groups: the control or healthy group, the diabetic control group, the group that received differentiated insulin-producing cells from bone marrow, and the group that received insulin treatment. To differentiate insulin-producing cells from bone marrow, the femoral bone marrow of rats was extracted using the flushing method. Differentiated cells were evaluated using dithizone-specific dye, anti-insulin-proinsulin antibodies, and anti-insulin beta receptors. Also, the expression of the pdx-I gene, as the specific gene of pancreatic cells, was examined by RT-PCR. The results showed that transplantation of insulin-producing cells could significantly increase blood insulin levels in diabetic rats. This increase intensified in the second stage of transplantation when more cells were injected into rats. Concerning decreasing blood sugar levels, differentiated cells were able to reduce blood sugar levels significantly. Even in the first stage of cell injection, in which the rats received a small number of cells, their blood sugar levels were controlled by these cells. As a result, the present study showed that repeated transplants of insulin-producing cells differentiated from bone marrow could decrease blood sugar and increase insulin levels.
