BACKGROUND: Women with higher serum calcium may be more likely to be diagnosed and die of ovarian cancer. We evaluated that finding in a large, prospective cohort. METHODS: We conducted a nested case-control study using a population-based biobank from Norway. We compared 202 ovarian cancer cases and 202 controls, matched for age, date at blood draw, and county of residence, with respect to serum calcium and albumin, adjusted for anthropometric variables. We evaluated risks using the entire follow-up period as well as 2-15 years and 16-25 years ("early" and "late", respectively)...

High spatial resolution in mass spectrometry imaging (MSI) is crucial to understanding the biology dictated by molecular distributions in complex tissue systems. Here, we present MSI using infrared matrix-assisted laser desorption electrospray ionization (IR-MALDESI) at 50 μm resolution. An adjustable iris, beam expander, and an aspherical focusing lens were used to reduce tissue ablation diameters for MSI at high resolution. The laser beam caustic was modeled using laser ablation paper to calculate relevant laser beam characteristics...

OBJECTIVE: Most of the ovarian cancers are diagnosed at advanced stages. As peritoneal carcinomatosis increases, especially when it extends to the diaphragm and intestinal mesos, probability of obtaining complete cytoreduction is reduced. Complete cytoreduction (residue zero: R0) is one of the main factors affecting survival [1-3]. Here we present a novel technique of stripping the peritoneal surfaces as a part of cytoreductive surgery in such cases. METHODS: A 55year-old woman diagnosed with peritoneal carcinomatosis was considered appropriate for primary cytoreduction after assessment of her thorax-abdominopelvic tomography, which revealed resectable intra-abdominal disease...

Quantitative proteomics has been made great progress in recent years. Label free quantitative proteomics analysis based on the mass spectrometry is widely used. Using this technique, we determined the differentially expressed proteins in the cisplatin-sensitive ovarian cancer cells COC1 and cisplatin-resistant cells COC1/DDP before and after the application of cisplatin. Using the GO analysis, we classified those proteins into different subgroups bases on their cellular component, biological process, and molecular function...

Cellular vaults are ubiquitous 13 mega Da multi-subunit ribonuceloprotein particles that may have a role in nucleocytoplasmic transport. Seventy percent of the vault's mass consists of a ≈100 kDa protein, the major vault protein. In humans, a drug resistance -associated protein, originally identified as lung resistance protein in metastatic lung cancer, was ultimately shown to be the previously described major vault protein. In this study, a partial major vault protein sequence was cloned from channel catfish...

The preoperative diagnosis of metastatic intestinal gastrointestinal stromal tumors (GIST) on cytology can be quite difficult at times. The present case characterizes the cytomorphological and immunocytochemical features of GIST, emphasizing the utility of fine-needle aspiration cytology (FNAC) in the evaluation of spindle cell tumors of gastrointestinal tract. An accurate and early diagnosis of GIST affects the treatment, primarily allowing the use of tyrosine kinase inhibitors in unresectable or metastatic cases...

Hydatid disease is a parasitic infection that most commonly affects the liver and lungs, although the disease can arise in any part of the body. Cysts may mimic many benign and malignant conditions. The diagnosis cannot be confirmed preoperatively in all cases. A 44-yr-old menopausal woman was admitted to the department of gynecology with complaints of abdominal distention. A fixed abdominopelvic mass was identified. Radiology revealed a 20-cm mass with branched septations and solid components. CA-125 level was 55 kU/L, and Risk of Malignancy Index-2 score was 880...

Quantification of β-1,4-galactosyltransferase (β-1,4-GT) activity is of considerable significance in the diagnosis of various cancers including lung and ovarian cancer. We report here the use of synthetic β-N-acetylglucosamine (NAG) ligands that contain hydrazide functional groups to determine galactosyltransferase activity by mass spectrometry. With hydrazide-linked β-d-NAG as the acceptor, the activity of β-1,4-GT is quantified by matrix-assisted laser desorption/ionization (MALDI)-time-of-flight (TOF) mass spectrometry (MS) with high efficiency...

AIM: Primary ovarian non-Hodgkin's lymphoma is a very rare disease. Median age at diagnosis is estimated at 42 years, something that leads to fertility preservation issues in many cases. This was a case report study, presenting a rare case of bilateral primary ovarian non-Hodgkin's lymphoma. CASE REPORT: A 38-year old nulliparous woman, underwent exploratory laparotomy because of bilateral ovarian masses. Left salpingooophorectomy, partial omentectomy and excision of an ovarian mass of the right ovary was performed...

The monodermal teratoma struma ovarii is a rare ovarian tumour; however, struma ovarii presenting with pseudo-Meigs' syndrome and raised cancer antigen (CA)-125 levels is even rarer. In elderly patients, this presentation can potentially lead to a misdiagnosis of a malignant ovarian carcinoma, resulting in unnecessary extensive surgery. We report a 55-year-old female who presented to the Lok Nayak Jai Prakash Narayan Hospital, New Delhi, India, in 2016 with progressive abdominal discomfort, fatigue and abdominal distention...

Deficiency of the 5-α-reductase enzyme has been found to affect male sexual development. We report an 18-year-old patient who was referred to an endocrinology clinic in Jizan, Saudi Arabia, in April 2014 with primary amenorrhoea, virilisation and a lack of secondary sex characteristics. As female external genitalia were present at birth, she had been raised as a female. Magnetic resonance imaging revealed no uterine or ovarian tissue in the pelvis and the presence of a scrotal sac. She was diagnosed with 5-α-reductase type 2 deficiency, a 46,XY disorder of sexual development...

To evaluate potential involvement of clathrin in endocytosis of vitellogenin (Vtg) by teleost oocytes, cDNAs encoding clathrin heavy chain (cltc) were cloned from ovaries of cutthroat trout. Quantitative PCR revealed three types of cltc (cltc-a1, cltc-a2, cltc-b) to be expressed in 10 different tissues including the ovary. The cltc-a1 alone exhibited a significant decrease in ovarian expression during vitellogenesis; this was correlated with a corresponding decrease in transcripts encoding the major Vtg receptor (Vtgr)...
