Recognition of a rare intrathoracic rib with computed tomography:
Mohammad Amin Abdollahifar,Shabnam Abdi,Mohammad Bayat,Reza Masteri Farahani,Hojjat Allah Abbaszadeh 대한해부학회 2017 Anatomy & Cell Biology Vol.50 No.1
One of the uncommon congenital variations is intrathoracic rib which a normal, a bifid, or an accessory rib lies within the thoracic cavity that is founded accidentally. Clinically, in most cases they are without symptoms; however, it may cause intrathoracic problems therefore it is important for radiologists and physicians to identify to prevent of excessive intervention and treatment during imaging diagnostic techniques of thoracic problems. In this report, we provide the case of a rare presentation of an intrathoracic rib in a 3-year-old boy arising from the inferior portion of a second rib based on findings from computed tomography. To our knowledge, this is only the second reported case of this type of intrathoracic rib that demonstrated with computed tomography.

Busulfan is an anticancer drug, which causes the apoptosis germ cells and azoospermia in humans and animals. Abnormal morphology of spermatozoa related to the male infertility. The sperm morphology is evaluation of sperm size, shape and appearance characteristics should be assessed by carefully observing a stained sperm sample under the microscope. Evaluation of sperm morphology has been considered as one of the most important factors for a successful fertilization and determining sperm quality. The mice were assigned to tow experimental groups: control and busulfan. Each group included six mice that were housed under standard conditions. The volume was estimated using the nucleator method. The sperm’s flegellum and mid-piece length was estimated by counting the number of intersections between the tails and Merz grid test line in an unbiased counting frame, superimposed on live images of sperms. Our results demonstrated a significant different in the volume and surface of the sperm’s head and the length of the sperm’s flagellum in the control and busulfan groups. Busulfan can effect on the volume of the sperm’s head and the length of the sperm’s flagellum in rat.

Prostate cancer is the most common cancer type in men and is the second cause of death, due to cancer, in patients over 50, after lung cancer. Prostate specific antigen (PSA) is a widely used tumor marker for prostate cancer. Recently, PSA is discovered in non-prostatic cancer tissues in men and women raising doubts about its specificity for prostatic tissues. PSA exists in low serum level in healthy men and in higher levels in many prostate disorders, including prostatitis and prostate cancer. Thus, a supplementary tumor marker is needed to accurately diagnose the cancer and to observe the patient after treatment. Recently, soluble human leukocyte antigen-G (sHLA-G) has been introduced as a new tumor marker for different cancer types, including colorectal, breast, lung, and ovary. The present descriptive-experimental study was carried out including patients with malignant prostate tumor, patients with benign prostate tumor, and a group of health men as the control group, as judged by an oncologist as well as a pathologist. After sterile blood sampling, sHLA-G was measured by enzyme-linked immunosorbent assay in each group. The data was then analyzed using one-way ANOVA. P≤0.05 was considered as statistically significant. The results showed that the mean of sHLA-G level was high in patients. Also, it was found that there was a significant difference in sHLA serum level between the three groups. The data revealed that sHLA-G can be a novel upplementary tumor marker in addition to PSA to diagnose prostate cancer.

Vitamin C restores ovarian follicular reservation in a mouse model of aging
Mohammad-Amin Abdollahifar,Nahid Azad,Ensieh Sajadi,Zahra Shams Mofarahe,Fatemeh Zare,Ali Moradi,Fatereh Rezaee,Mohammad Gholamin,Shabnam Abdi 대한해부학회 2019 Anatomy & Cell Biology Vol.52 No.2
Ovarian aging is related to the reduction of oocyte quality and ovarian follicles reservation leading to infertility. Vitamin C is a natural antioxidant which may counteract with adverse effects of aging in the ovary. The aim of this study was to evaluate the possible effect of vitamin C on NMRI mice ovarian aging according to the stereological study. In this experimental study, 36 adult female mice (25–30 g) were divided into two groups: control and vitamin C. Vitamin C (150 mg/kg/day) were administered by oral gavage for 33 weeks. Six animals of each group were sacrificed on week 8, 12, and 33, and right ovary samples were extracted for stereology analysis. Our data showed that the total volume of ovary, cortex, medulla and corpus luteum were significantly increased in vitamin C group in comparison to the control groups (P≤0.05). In addition, the total number of primordial, primary, secondary, and antral follicles as well as granulosa cells were improved in vitamin C group in compared to the control groups (P≤0.05). No significant difference was observed in total volume of oocytes in antral follicles between control and vitamin C groups. Our data showed that vitamin C could notably compensate undesirable effects of ovarian aging in a mouse model.
