Domestication in dry-cured meat fungi: Convergent specific phenotypes and horizontal gene transfers without strong genetic subdivision.

Some fungi have been domesticated for food production, with genetic differentiation between populations from food and wild environments, and food populations often acquiring beneficial traits through horizontal gene transfers (HGTs). Studying their adaptation to human-made substrates is of fundamental and applied importance for understanding adaptation processes and for further strain improvement. We studied here the population structures and phenotypes of two distantly related species used for dry-cured meat production, , the most common species in the dry-cured meat food industry, and , used locally by farms.

Strong effect of Penicillium roqueforti populations on volatile and metabolic compounds responsible for aromas, flavor and texture in blue cheeses.

Studies of food microorganism domestication can provide important insight into adaptation mechanisms and lead to commercial applications. Penicillium roqueforti is a fungus with four genetically differentiated populations, two of which were independently domesticated for blue cheese-making, with the other two populations thriving in other environments. Most blue cheeses are made with strains from a single P.

Independent domestication events in the blue-cheese fungus Penicillium roqueforti.

Domestication provides an excellent framework for studying adaptive divergence. Using population genomics and phenotypic assays, we reconstructed the domestication history of the blue cheese mould Penicillium roqueforti. We showed that this fungus was domesticated twice independently.

Carotenoids from the ripening bacterium impart color to the rind of the French cheese, Fourme de Montbrison (PDO).

Rind color of some high-value PDO cheeses is related to the presence of carotenoids, but little is known about the structure of the pigmented compounds and their origin. Our objective was to describe the carotenoids extracted from the rind of a French cheese, Fourme de Montbrison, and to compare them with the pigments produced by a bacterial strain used as an adjunct culture in the cheese ripening process. Eleven carotenoids were detected in the cheese rinds or in the biomass of .

The twenty-first century role of Piver-Rutledge type III radical hysterectomy and FIGO stage IA, IB1, and IB2 cervical cancer in the era of robotic surgery: a personal perspective.

Type III radical hysterectomy reported in 1974 by Piver, Rutledge, and Smith is considered worldwide by many as the standard surgical therapy for invasive cervical carcinoma stage IB and IIA. With the increasing number of robotic surgeries being performed for early stage cervical cancer worldwide, the purpose of the paper is to present our personal perspective of the 21st century role of Piver-Rutledge type III radical hysterectomy for stage IB cervical cancer in the era of robotic surgery using the da Vinci robot.

21st century challenge of ovarian cancer in the elderly. A personal perspective.

The incidence of ovarian cancer is highest in women over 70 years old, and the disease is the leading cause of death from gynecologic malignancies in the United States and Europe. Nevertheless, improving the quality of medical care for elderly women with ovarian cancer continues to be a challenge. This paper presents the major issues related to the surgical management of presumed early-stage ovarian cancer, surgery and chemotherapy for advanced-stage ovarian cancer in the elderly, and a proposed 21st century algorithm for dealing with these major issues in ovarian cancer in the elderly.

Consideration of hereditary nonpolyposis colorectal cancer in BRCA mutation-negative familial ovarian cancers.

Background: Inherited mutations account for approximately 10% of all epithelial ovarian cancers. Breast cancer (BRCA1 and BRACA2) gene mutations are responsible for up to 85% of inherited breast and/or ovarian cancer. Another condition that has been associated with ovarian cancer is hereditary nonpolyposis colorectal cancer syndrome (HNPCC), which carries a lifetime risk of up to 13% for ovarian cancer.

The 21st century role of Piver type II hysterectomy in FIGO stage IA, IB cervical cancer: a personal perspective.

Class II modified radical hysterectomy reported in 1974 by Piver, Rutledge and Smith for cervical cancer is an extended hysterectomy that has less dissection of the ureter from the paracervical tissues, ligation of the uterine vessels just medial to the ureter to ensure preservation of the distal ureteral blood supply, and less radical parametrectomy preserving the lateral parametrium. The authors present a 21st century personal perspective on the use of a type II hysterectomy based on the 1994 FIGO changes in classification of Stage IAI, IA2, IBI and IB2.

Contribution of BRCA1 and BRCA2 mutations to inherited ovarian cancer.

A total of 283 epithelial ovarian cancer families from the United Kingdom (UK) and the United States (US) were screened for coding sequence changes and large genomic alterations (rearrangements and deletions) in the BRCA1 and BRCA2 genes. Deleterious BRCA1 mutations were identified in 104 families (37%) and BRCA2 mutations in 25 families (9%). Of the 104 BRCA1 mutations, 12 were large genomic alterations; thus this type of change represented 12% of all BRCA1 mutations.

Screening for the BRCA1-ins6kbEx13 mutation: potential for misdiagnosis. Mutation in brief #964. Online.

Misdiagnosis of a germline mutation associated with an inherited disease syndrome can have serious implications for the clinical management of patients. A false negative diagnosis (mutation missed by genetic screening) limits decision making about intervention strategies within families. More serious is the consequence of a false positive diagnosis (genetic test suggesting a mutation is present when it is not).

The role of hereditary nonpolyposis colorectal cancer in the management of familial ovarian cancer.

Purpose: Familial ovarian cancer is most often associated with hereditary breast and ovarian cancer, implicating mutations in the BRCA1 and BRCA2 genes. Hereditary nonpolyposis colorectal cancer, another common syndrome, is also associated with ovarian cancer and is caused by DNA mismatch repair genes. We sought to identify the role of hereditary nonpolyposis colorectal cancer in women with family histories of ovarian cancer.

Role of prophylactic hysterectomy in patients at high risk for hereditary cancers.

Background: Current surgical recommendations for ovarian cancer prophylaxis in women at high risk of developing ovarian cancer include bilateral salpingo-oophorectomy (risk-reducing salpingo-oophorectomy (RRSO)). The role of hysterectomy is unclear. We sought to determine outcomes following prophylactic surgery in high-risk women.

Oral contraceptive use and ovarian cancer risk among carriers of BRCA1 or BRCA2 mutations.

Women with mutations of the genes BRCA1 or BRCA2 are at increased risk of ovarian cancer. Oral contraceptives protect against ovarian cancer in general, but it is not known whether they protect against the disease in carriers of these mutations. We obtained self-reported lifetime histories of oral contraceptive use from 451 women who carried mutations of BRCA1 or BRCA2.

Assessment of family cancer history collection and utilization in patient care.

Objectives: This study was conducted to determine whether patients and accompanying persons visiting the Gynecologic Oncology Clinic were aware if a family cancer history was recorded and utilized in their medical care; whether they were aware of the importance of a family cancer history, and whether they would like to learn more about familial cancer.

Methods: Sixteen- and 17-item self-report questionnaires were administered to patients and their accompanying persons, respectively, who were visiting the Gynecologic Oncology Clinic. All responses were anonymous.

Histopathology, FIGO stage, and BRCA mutation status of ovarian cancers from the Gilda Radner Familial Ovarian Cancer Registry.

Studies of the histopathology of ovarian cancer arising in patients with germline mutations in BRCA1 or BRCA2 have shown inconsistent findings. We analyzed the large number of tumors from women enrolled in the Gilda Radner Familial Ovarian Cancer Registry for correlations between histopathology and BRCA mutation status. Histopathology slides and reports were reviewed for histology, grade, and stage for cancers of the ovary or peritoneum in 220 women from 126 Gilda Radner Familial Ovarian Cancer Registry families.

BRCA1/2 mutation status influences somatic genetic progression in inherited and sporadic epithelial ovarian cancer cases.

Metaphase comparative genomic hybridization was used to analyze the spectrum of genetic alterations in 141 epithelial ovarian cancers from BRCA1 and BRCA2 mutation carriers, individuals with familial non-BRCA1/2 epithelial ovarian cancer, and women with nonfamilial epithelial ovarian cancer. Multiple genetic alterations were identified in almost all tumors. The high frequency with which some alterations were identified suggests the location of genes that are commonly altered during ovarian tumor development.

A ten-year remission maintained by 6,272 mg (3,920 mg/m2) cumulative dose of cisplatin-based chemotherapy for recurrent epithelial ovarian cancer.

Since cisplatin is a heavy metal, renal and neurotoxicity is considered to be dose limiting in solid tumors. The current case is unusual in that remission has been maintained in a patient with recurrent epithelial ovarian cancer by cisplatin-based chemotherapy without evidence of renal or neurotoxicity, while receiving a total dose of 6,270 mg (3,920 mg/m2) of cisplatin over 11 1/2 years.

The use of lymphadenectomy in clinical stage I endometrial adenocarcinoma at a large community hospital.

Unlabelled: PURPOSE AND MATERIALS AND METHODS: Because of the inaccuracies in clinical staging of endometrial cancer, the International Federation of Gynecology and Obstetrics (FIGO) in 1988 changed the staging of endometrial cancer to surgical staging consisting of intraoperative findings and histologic evaluation of the specimen. A decade later, 1998, the United States Society of Gynecologic Oncologists published Practice Guidelines for the surgical staging of endometrial cancer. The purpose of this study was to review the use of lymph node sampling and peritoneal washings in 100 consecutive cases of clinical stage I endometrial cancer and compare these results to the Practice Guidelines of the Society of Gynecologic Oncologists.
