central nervous system atypical teratoid/rhabdoid tumor during infancy is a rare, highly aggressive tumor most commonly seen in the cerebellar area. herein we describe the case of a 4-month-old baby who presented with convulsions. pathologic examination of her cerebellar mass showed an atypical teratoid/rhabdoid tumor. the patient died 5 days after surgery despite complete excision of the mass ...
Abstract Reactive soft tissue lesions are common in the oral cavity. These lesions usually occur as a painless non-neoplastic proliferation. Surgical excision of these lesions will cause aesthetic and mucogingival problems in the area. In this case, a prominent lesion in the anterior maxilla of a 40-year-old woman had recurred after two years. Surgical treatment was performed with complete ...
Based on “teleological coherence” hypothesis, all of the systems of an organism aim to achieve a common goal and when the boundaries between self/nonself are broken in one system, the possibility that they will be destroyed in other systems is increased. On this basis the present study aimed to investigate self-destructive tendencies and integrative self-knowledge of MS patients (N = 88) and no...
The low frequency of self-peptide-specific T cells in the human preimmune repertoire has so far precluded their direct evaluation. Here, we report an unexpected high frequency of T cells specific for the self-antigen Melan-A/MART-1 in CD8 single-positive thymocytes from human histocompatibility leukocyte antigen-A2 healthy individuals, which is maintained in the peripheral blood of newborns and...
Cellular DNA repair is a frontline system that is responsible for maintaining genome integrity and thus preventing premature aging and cancer by repairing DNA lesions and strand breaks caused by endogenous and exogenous mutagens. However, it is also the principal cellular system in cancer cells that counteracts the killing effect of the major cancer treatments e.g. chemotherapy and ionizing rad...
In DNA excision repair of mammalian cells, the processing of ADP-ribose by the poly ADP-ribosylation system of chromatin is stimulated several thousand-fold. Most of this turnover is associated with the automodification reaction of the nuclear enzyme poly(ADP-ribose) polymerase and the degradation of polymerase-bound polymers by the enzyme poly(ADP-ribose) glycohydrolase. The automodification c...
Background: Breast conserving surgery is the treatment of choice in surgical management early-stage breast cancer developed countries, while mastectomy has remained most practiced developing countries. The aim study was to describe outcomes a cohort patients who had country. Methods: retrospective review were offered between January 2018 and December 2020 at Jos University Teaching Hospital FOM...
Background: Skin lesions and need for tissue evaluation, makes skin surgery an important part of treatment. Each excision is accompanied by skin repair. One of side effects of lesion excision is dog ear and cosmetic problems, particulary on face. Case Report: A middle age woman presented with an old leishmaniosis scar in her face. she asked how can we remove the lesion with minimal scar. In ...
