RESUMO

Plasmacytomas rarely affect the skull base and may be found as an isolated lesion or as a part of multiple myeloma. The typical feature of plasmacytomas is aggressive bone destruction in the skull. It is often confused with the chordoma of the clivus. The most common location for skull-base plasmacytomas is the nasopharynx. The most commonly affected cranial nerve in clivus tumors is the abducens nerve. In our 64-year-old male case, a plasmacytoma was detected in the clivus. There was ptosis and decreased vision due to optic nerve and oculomotor nerve involvement due to the plasmacytoma. Radiotherapy was applied for the treatment.

RESUMO

Infertility affects a significant portion of the reproductive population and is caused by structural and hormonal factors. The prevalence of congenital uterine anomalies is 3%-4%, with the most common anomaly being septate uterus. However, further research is needed to determine whether these anomalies can cause infertility. In this study, we compared the morphometric parameters of the uterus of fertile and infertile individuals. Based on the data obtained, we aimed to determine the parameters to be evaluated for fertility prediction and to investigate the effect of uterine septum on fertility. The uteruses of 55 infertile and 80 fertile individuals between the age range of 20-45 years were analyzed retrospectively using magnetic resonance images. Infertile individuals were categorized into two groups according to the reasons for infertility: Group I, which included women with congenital uterine anomalies (septate uterus), and Group II, which included women with tubal and male factors. Group III comprised fertile individuals. Uterine length (UL), uterine body length (UbL), cervical length (CxL), uterine cavity length (UcL), anteroposterior diameter (APD), transverse diameter (TD), fundal thickness (FT), and ostial distance (OD) were measured. The uterine positions were examined. The data of uterine variables were evaluated statistically according to age and groups. The mean ages of individuals in Groups I, II, and III were 29.88 ± 6.69, 29.21 ± 4.59, and 27.45 ± 5.43 years, respectively. Significant differences were observed between the groups in terms of UL, UbL, CxL, UcL, APD, FT, and OD variables (p < 0.05), except for TD (p > 0.05). We observed that UL, UcL, length/width ratio, and APD parameters are important factors that influence fertility. Evaluating these parameters before septum resection would be useful in predicting the contribution of this surgical operation to fertility.

RESUMO

Developing and implementing computational algorithms for the extraction of specific substructures from molecular graphs (in silico molecule fragmentation) is an iterative process. It involves repeated sequences of implementing a rule set, applying it to relevant structural data, checking the results, and adjusting the rules. This requires a computational workflow with data import, fragmentation algorithm integration, and result visualisation. The described workflow is normally unavailable for a new algorithm and must be set up individually. This work presents an open Java rich client Graphical User Interface (GUI) application to support the development of new in silico molecule fragmentation algorithms and make them readily available upon release. The MORTAR (MOlecule fRagmenTAtion fRamework) application visualises fragmentation results of a set of molecules in various ways and provides basic analysis features. Fragmentation algorithms can be integrated and developed within MORTAR by using a specific wrapper class. In addition, fragmentation pipelines with any combination of the available fragmentation methods can be executed. Upon release, three fragmentation algorithms are already integrated: ErtlFunctionalGroupsFinder, Sugar Removal Utility, and Scaffold Generator. These algorithms, as well as all cheminformatics functionalities in MORTAR, are implemented based on the Chemistry Development Kit (CDK).
