Stick cancer ovarian

This paper will review a remarkable new approach to in vitro maturation "IVM" of oocytes from ovarian tissue, based on our results with in vitro oogenesis from somatic cells. As an aside benefit we also have derived a better understanding of ovarian longevity from ovary transplant. We have found that primordial follicle recruitment is triggered by tissue pressure gradients. Increased pressure holds the follicle in meiotic arrest and prevents recruitment. Therefore recruitment occurs first in the least dense inner tissue of the cortico-medullary junction...

A rapid and simple methodology for the biomolecular analysis of single cells and microenvironments via a stick-and-peel plasmonic sensing platform is reported. Substrate-bound assemblies of plasmonic gold nanoparticles linked by reconfigurable oligonucleotides undergo disassembly upon target binding. Changes in the light scattering intensity of thousands of discrete nanoparticle assemblies are extrapolated concomitantly to yield the mapping of local target concentrations. The methodology is completely free of labelling, purification and separation steps...

It is currently hoped that deaths from extra-uterine high-grade serous cancer (HGSC) will be reduced via opportunistic salpingectomy in healthy women. Accumulated data implicate the fimbria as a site of origin and descriptive molecular pathology and experimental evidence strongly support a serous carcinogenic sequence in the Fallopian tube. Both direct and indirect ('surrogate') precursors suggest that the benign tube undergoes important biological changes after menopause, acquiring abnormalities in gene expression that are often shared with malignancy, including PAX2, ALDH1, LEF1, RCN1, RUNX2, beta-catenin, EZH2, and others...

Non-viral gene-delivery platforms have been developed to co-deliver chemotherapeutics and siRNAs. The synergistic effects between shRNAs against survivin and Paclitaxel (PTX) using supramolecular micelles self-assembled from the host PEI-CyD (PC) composed of β-cyclodextrin (β-CyD) and polyethylenimine (PEI, Mw 600) and guest adamantine conjugated PTX (Ada-PTX) in combination cancer therapy are investigated. The Ada-PTX is encapsulated inside the core and shRNA sticks to the shell surface. The physicochemical properties of these supramolecular nanoparticles are favorable to cell uptake and intracellular trafficking...

Ovarian cancer remains the most frequently lethal of the gynecologic cancers owing to the late detection of this disease. Here, by using human specimens and three mouse models of ovarian cancer, we tested the feasibility of nonlinear imaging approaches, the multiphoton microscopy (MPM) and second harmonic generation (SHG) to serve as complementary tools for ovarian cancer diagnosis. We demonstrate that MPM/SHG of intrinsic tissue emissions allows visualization of unfixed, unsectioned, and unstained tissues at a resolution comparable to that of routinely processed histologic sections...

PURPOSE: Smell and taste changes during chemotherapy are significant complaints of cancer patients. Loss of olfactory/gustatory function can lead to malnutrition, weight loss, and possibly a prolonged morbidity of chemotherapy-induced adverse effects, decreased quality of life, poor compliance, and even decreased therapy response. This prospective study comprehensively investigated, to our knowledge for the first time, smell and taste changes in a cohort of 87 patients undergoing chemotherapy for breast cancer or gynecologic malignancies...

The evaluation of the frequency of complications that arise after colostomies performed for colorectal and genital neoplasm, and also the treatment possibilities for these complications. In Colţea Hospital, Surgical Department during 1984-2002 there have been admitted and surgically treated 891 patients with colorectal cancers, among which, 484 had rectosigmoidal neoplasm. We have treated 25 patients with complicated genital neoplasm (19 rectovaginal and recto-bladder-vaginal fistulas following cervical cancers, 5 pelvic tumoral blocks following ovarian cancers and a vulvar cancer with local invasion)...

Cancer chemotherapy celebrated its fiftieth anniversary last year. It was in 1945 that wartime research on the nitrogen mustards, which uncovered their potential use in the treatment of leukaemias and other cancers, was first made public. Fifty years later, more than sixty drugs have been registered in the USA for the treatment of cancer, but there are still lessons to be learnt. One problem, paradoxically, is that many anticancer agents produce a response in several different classes of the disease. This means that once a new agent has been shown to be effective in one cancer, much effort is devoted to further investigations of the same drug in various combinations for different disorders...

Preliminary results of surgical treatment in 24 patients with pathologic fractures or metastatic long bone defects impending fracture are presented. Fourteen females and 10 males aged 36-72 years with femoral (18 cases), tibial (4 cases) or humeral (2 cases) involvement were followed-up for 6-48 months. In 12 patients the pain ceased or decreased, 3 patients occasionally required non narcotic analgesics, in 9 cases the pain continued. All patients with lower extremity involvement were able to ambulate with an aid of walking sticks, 2 patients with humeral fracture resumed activities of daily living...
