BACKGROUND: Contemporary medicine does not concern the issue of dosimetry in photodynamic diagnosis (PDD) but follows the photosensitizer (PS) producers recommendation. Most preclinical and clinical PDD studies indicate a considerable variation in the possibility of visualization and treatment, as e.g. in case of cervix lesions. Although some of these variations can be caused by the different histological subtypes or various tumor geometries, the issue of varying PS concentration in the tumor tissue volume is definitely an important factor...

Primary cutaneous angiosarcoma is a rare vascular tumor usually affecting the whole body, and its hypermetabolic features on F-FDG PET/CT may be confused with those of infection, metastasis, or primary malignancy. This is a case report of a cutaneous angiosarcoma of the lower anterior abdomen showing increased FDG uptake on F-FDG PET/CT mimicking a cutaneous metastasis in an 84-year-old woman with cervical cancer.

The recent investigation on PARK-2, a putative tumor suppressor gene, has found that it has been altered in multiple human malignancies. However, the clinical impact of PARK-2 alteration in uterine cervix carcinoma has not yet been studied. Therefore, we aimed to examine mutations, promoter hypermethylation, and protein expression of PARK-2 among the North Indian patients and their association with clinical parameters to evaluate the implication of PARK-2 in the genesis of cervical cancer. A total of 168 patient samples were processed for mutational analysis by single-strand conformation polymorphism, sequencing, and further in silico analysis of the identified mutations...

Human papillomavirus (HPV) can activate Toll-like receptor (TLR)/nitric oxide (NO) signaling pathways; however, whether the TLR/NO pathway is involved in cervical cancer caused by high-risk HPV (HR-HPV) remains unclear. In this study, 43 HR-HPV-positive patients with cervical cancer (CC group), 39 HR-HPV-positive patients with a healthy cervix (HR-HPV group), and 33 HR-HPV-negative controls were recruited. NO concentration in cervical canal and expression of inducible NO synthase (iNOS) in cervical tissues were detected...

Koen Van Gansbeke, Eirik Johansson Solum, Sandra Liekens, Anders Vik, Trond Vidar Hansen
The regioselective synthesis of estrogens and their derivatives continues to be of interest. Most reported syntheses require multistep protocols associated with poor overall yield and lack of regioselectivity. New preparative protocols are still desired. Herein, 11 2-alkylated 17β -estradiol analogs were synthesized in a highly regioselective manner. The products were obtained using a convenient, one pot and high-yielding protocol. The anti-proliferative activity of the compounds was tested in human T-cell leukemia (CEM), human cervix carcinoma (HeLa) and human dermal microvascular endothelial (HMEC-1) cells...

Cervical cancer is an important public health problem. Pap smear is the leading strategy of screening programs for cervical cancer worldwide. However, delayed diagnosis leads to more aggressive and less effective treatments. Patients with uterine cervix malignancies who are referred for radiotherapy have advanced-stage disease, which results in high rates of locoregional recurrence. The use of radiotherapy as a treatment for cervical cancer causes morphological changes in neoplastic and non-neoplastic epithelial cells, as well as in stromal cells, which make it difficult to diagnose the residual lesion, resulting in a dilemma in cytopathological routine...

Cancer besides being a leading cause of mortality also creates a myriad of morbidities in survivors whether treated or untreated. Among women surviving after gynecological malignancies sexual dysfunction is a morbidity unexplored in Indian context because of cultural barriers. With the increasing proportion of women surviving carcinoma of the cervix, quality of life has become an important clinical issue. Despite the immense distress it causes in patients, sexual dysfunction is neither screened nor treated in Indian scenario...

Adenocarcinoma admixed with neuroendocrine carcinoma of the uterine cervix is a rare malignancy with a poor prognosis, and few reports have described the cytological features of this carcinoma. To characterize the cytological features of this malignancy in cervical smears, we report a case of a 52-year-old Japanese woman with cervical adenocarcinoma admixed with small cell neuroendocrine carcinoma (SCNEC). Cytologically, there were two types of cells with different sizes. The smaller cells formed clusters, which showed a partially Indian file pattern, a high nuclear/cytoplasmic ratio, and hyperchromatic nuclei...

From flocking birds to swarming insects, interactions of organisms large and small lead to the emergence of collective dynamics. Here, we report striking collective swimming of bovine sperm in dynamic clusters, enabled by the viscoelasticity of the fluid. Sperm oriented in the same direction within each cluster, and cluster size and cell-cell alignment strength increased with viscoelasticity of the fluid. In contrast, sperm swam randomly and individually in Newtonian (nonelastic) fluids of low and high viscosity...

The cardinal ligament (CL) is one of the major pelvic ligaments providing structural support to the vagina/cervix/uterus complex. This ligament has been studied mainly with regards to its important function in the treatment of different diseases such as surgical repair for pelvic organ prolapse and radical hysterectomy for cervical cancer. However, the mechanical properties of the CL have not been fully determined, despite the important in vivo supportive role of this ligament within the pelvic floor. To advance our limited knowledge about the elastic and viscoelastic properties of the CL, we conducted three consecutive planar equi-biaxial tests on CL specimens isolated from swine...
