The morphology of the female Cyrtobagous salviniae Calder and Sands reproductive system is similar to other weevil species being meroistic and telotrophic. The reproductive system is composed of 2 ovaries each containing 2 ovarioles where the follicles mature. A physiological age grading system was developed where the continuum of ovarium development was divided into 2 nulliparous and 3 parous classes. This was based on the differentiation of the ovarioles, presence, and appearance of follicular relics, cuticle hardness/coloration, and fat body quantity/appearance...

INTRODUCTION: The role of autoimmune responses against central nervous system (CNS) antigens in encephalitis presenting with non-classified neurologic or psychiatric symptoms has been appreciated in the past decade. Paraneoplastic limbic encephalitis has a poor prognosis and is most commonly associated with lung, ovarium, and testicular neoplasms, leading to immune reactions against intracellular antigens (anti-Hu/ANNA1, anti-Ri/ANNA2, anti-CV2/CRMP5 and anti-Ma2/Ta). In contrast, the recently described autoimmune encephalitis subtypes present with a broad spectrum of symptoms, respond to autoimmune therapies well and usually associate with autoantibodies against neuronal cell surface receptors (NMDAR, GABAB R, AMPAR) or synaptic proteins (LGI1, CASPR2)...

The diagnosis of leptomeningeal metastases (LM) of solid tumors is complicated due to low sensitivities of both magnetic resonance imaging (MRI) and cytology. MRI has a sensitivity of 76% for the diagnosis of LM and cerebrospinal fluid (CSF) cytology has a sensitivity of 44-67% at first lumbar puncture which increases to 84-91% upon second CSF sampling. Epithelial cell adhesion molecule (EpCAM) is expressed by solid tumors of epithelial origin like non-small-cell lung cancer, breast cancer or ovarium cancer...

AXIN2 gene plays a crucial role in morphogenesis of craniofacial area and is essential for tooth development. AXIN2 gene is one of the most studied genes associated with tooth agenesis, the most common defect of dentition in humans. Polymorphic variants in AXIN2 gene are discussed in relation to the occurrence of the tooth agenesis but also as an indication of the risk of cancer. Mutations in AXIN2 gene were found in patients with colorectal or hepatocellular carcinoma, prostate cancer, ovarium or lung cancer...

Diminished ovarian reserve (DOR) refers to the decreased production of mature ova in ovarium and decreased quality of oocyte, leading to deficiency of the female sex hormone and decreased fertility. DOR can also develop into premature ovarian failure, which affects female life quality and constitutes an important cause of female infertility. A fast lifestyle, environmental deterioration and accumulated understanding of this disease, have led to an increase in the incidence of DOR. Therefore, reasonable and effective treatment for DOR is particularly important to improve ovarian function and female life quality as well as reduce infertility...

Increasingly, the discovery and characterization of small regulatory RNAs from a variety of organisms have all required deep-sequencing methodologies. However, the crux to successful deep-sequencing analysis depends upon optimal construction of a cDNA library compatible for the high-throughput sequencing platform. Challenges to small RNA library constructions arise when dealing with minute tissue samples because certain structural RNA fragments can dominate and mask the desired characterization of regulatory small RNAs like microRNAs (miRNAs), endogenous small interfering RNAs (endo-siRNAs), and Piwi-interacting RNAs (piRNAs)...

Environmental exposure to electromagnetic radiation (EMR) has been increasing with the increasing demand for communication devices. The aim of the study was to discuss the mechanisms and risk factors of EMR changes on reproductive functions and membrane oxidative biology in females and males. It was reported that even chronic exposure to EMR did not increase the risk of reproductive functions such as increased levels of neoantigens abort. However, the results of some studies indicate that EMR induced endometriosis and inflammation and decreased the number of follicles in the ovarium or uterus of rats...

We report here a case of pulmonary benign metastasizing leiomyoma (BML) from the uterus. A 48-year-old woman was admitted to our hospital because of multiple pulmonary nodules on the chest radiograph 7 years after total hysterectomy with removal of the left ovarium for uterine leiomyoma. A specimen of the lesion obtained by a thoracoscopic lung biopsy was consistent with leiomyoma. Histological re-evaluation of the uterine myoma showed similar histology as compared with the lung tumor. Immunohistological staining for both estrogen and progesterone receptors on the lung tissue was positive...

To clarify the mechanisms of the formation of peritoneal dissemination, a new animal model by the i.p. inoculation of highly metastatic gastric cancer cell line MKN-45-P was developed. Peritoneal dissemination with bloody ascites was found in 100% of nude mice, injected 1x10(7) MKN-45-P cells in suspension into the peritoneal cavity. By a highly sensitive method for specific detection of metastasized human tumor cells in nude mice using polymerase chain reaction, a human beta-globin-related sequence in the DNA from various parts of the peritoneum was specifically amplified and detected by gel electrophoresis and by a specific oligonucleotide probe...

This is an account of a case of primary adenocarcinoma of the small intestine with peritoneal dissemination successfully treated with chemotherapy. A 64-year-old woman was admitted with a complaint of severe abdominal distension. Abdominal computerized tomography revealed a bowel obstruction with tumor and the remarkable small bowel dilation of oral side of tumor. The tumor was found at surgery to be at the ileum 15 cm proximal from the ileocecal region. Peritoneal dissemination was recognized around the ileocecal region, so ileum partial resection was performed for the primary cancer lesion and dissemination region...

Pseudo-Meigs' syndrome caused by ovarian metastasis from colorectal cancer is extremely rare. The clinical symptoms of pleural effusion and ascites that are characteristics of pseudo-Meigs' syndrome are quite similar to those of terminal-stage colon cancer. Therefore, recognizing the clinical characteristics of pseudo-Meigs' syndrome is important. We investigated the prognosis and clinicopathological factors including age, location of the primary cancer, histology, wall depth, curative degree, synchronous/metachronous, unilateral/bilateral, lymph node metastasis, peritoneal dissemination, serum CEA level, venous invasion, and lymphatic invasion, in 5 cases of pseudo-Meigs' syndrome (PM group) and compared these findings with those of 10 cases with ovarian metastasis from colorectal cancer (control group) without pseudo-Meigs' syndrome...
