Sidika E Karakas
Polycystic ovary syndrome (PCOS) is the most common endocrine disorder affecting young women. Even though the definition of PCOS has changed over the years, all diagnostic criteria include two or more of the following: oligomenorrhea/oligoovulation/anovulation, androgen excess and polycystic ovaries (PCO). Traditional method of assessing the ovarian morphology has been transvaginal pelvic ultrasound. Recent studies support that serum anti-Mullerian hormone (AMH) levels correlate with the number of ovarian follicles and cysts...

BACKGROUND: Polycystic ovarian syndrome (PCOS) is a heterogeneous disorder with clinical features shared with functional hypogonadotrophic hypogonadism (FHH). AIM: To investigate the usefulness of an elevated (>40 pmol/L) anti-Mullerian hormone (AMH) in identifying PCOS and distinguishing PCOS from FHH. MATERIALS AND METHODS: 141 patients with an elevated AMH and body mass index either <20 kg/m(2) (lean) or >30 kg/m(2) (obese) were selected and three subgroups analysed - obese, lean, lean with suspected FHH...

REVIEW
Pui-Wah Choi, Shu-Wing Ng
The majority of studies on microRNA-200 family members (miR-200s) in human cancers are based on the premise that miR-200s maintain epithelial cell integrity by suppressing epithelial-mesenchymal transition (EMT) through direct inhibition of mesenchymal transcription factors zinc finger E-box-binding homeobox 1/2 (ZEB1/ZEB2) and transforming growth factor-β (TGF-β), a potent inducer of EMT. Hence, downregulation of miR-200 in cancer cells promotes EMT and cancer metastasis. Yet, miR-200s are highly expressed in ovarian cancer, and ovarian cancer metastasizes primarily by dissemination within the pelvic cavity...

Valosin Containing Protein (VCP) disease is an autosomal dominant multisystem proteinopathy caused by mutations in the VCP gene, and is primarily associated with progressive muscle weakness, including atrophy of the pelvic and shoulder girdle muscles. Currently, no treatments are available and cardiac and respiratory failures can lead to mortality at an early age. VCP is an AAA ATPase multifunction complex protein and mutations in the VCP gene resulting in disrupted autophagic clearance. Due to the rarity of the disease, the myopathic nature of the disorder, ethical and practical considerations, VCP disease muscle biopsies are difficult to obtain...

Non-Islet Cell Tumour Induced Hypoglycaemia (NICTH), presenting with recurrent fasting hypoglycaemia is a very rare paraneoplastic syndrome. It usually presents with large metastatic mesenchymal tumours. NICTH secondary to Gastrointestinal Stromal Tumour (GIST) is even rarer. Diagnosis of NICTH is based on the low serum insulin level, low serum concentrations of Insulin Like Growth Factor (IGF-I) and IGF binding protein- III (IGFBP-III) in combination with elevated concentrations of pro-IGF-II. Various Immunohistochemical (IHC) markers are integral to diagnosis of GIST namely 2-deoxyglucose-6-phosphate phosphatase -1(DOG-1), Cluster Differentiation 34 (CD 34), Cluster Differentiation 117 (CD117)...

Objectives: Determination of the primary site of origin for mucinous neoplasms identified in the peritoneal and/or pelvic cavities may be challenging, with major differential diagnoses including appendiceal mucinous neoplasm (AMN) and ovarian mucinous neoplasm (OMN). Special AT-rich sequence binding protein 2 (SATB2) has been shown to be highly selectively expressed in the lower gastrointestinal tract, including the appendix. Methods: We investigated the utility of a dual stain (DS) with SATB2 or caudal type homeobox 2 (CDX2) and cytokeratin 20 (CK20) or villin in distinguishing AMNs from OMNs...

Bone morphogenetic proteins (BMPs) play crucial roles in vertebrate developmental process and are associated with the mechanisms which drive early skeletal development. As a first approach to elucidating the role of BMPs in regulating fish bone formation and growth, we describe the cloning, expression profiling and promoter functional analysis of bmp6 and bmp7 in tongue sole (Cynoglossus semilaevis). The full length of bmp6 and bmp7 cDNA sequences is 1939 and 1836 bp, which encodes a protein of 428 and 427 amino acids, respectively...

The fungus Batrachochytrium dendrobatidis (Bd) causes chytridiomycosis, a lethal epizootic disease of amphibians. Rapid identification of the pathogen and biosecurity is essential to prevent its spread, but current laboratory-based tests are time-consuming and require specialist equipment. Here, we describe the generation of an IgM monoclonal antibody (mAb), 5C4, specific to Bd as well as the related salamander and newt pathogen Batrachochytrium salamandrivorans (Bsal). The mAb, which binds to a glycoprotein antigen present on the surface of zoospores, sporangia and zoosporangia, was used to develop a lateral-flow assay (LFA) for rapid (15 min) detection of the pathogens...

Seahorses have a specialized morphology that includes a toothless tubular mouth, a body covered with bony plates, a male brood pouch, and the absence of caudal and pelvic fins. Here we report the sequencing and de novo assembly of the genome of the tiger tail seahorse, Hippocampus comes. Comparative genomic analysis identifies higher protein and nucleotide evolutionary rates in H. comes compared with other teleost fish genomes. We identified an astacin metalloprotease gene family that has undergone expansion and is highly expressed in the male brood pouch...

The cytokine gamma interferon (IFN-γ) induces cell-autonomous immunity to combat infections with intracellular pathogens, such as the bacterium Chlamydia trachomatis The present study demonstrates that IFN-γ-primed human cells ubiquitinate and eliminate intracellular Chlamydia-containing vacuoles, so-called inclusions. We previously described how IFN-γ-inducible immunity-related GTPases (IRGs) employ ubiquitin systems to mark inclusions for destruction in mouse cells and, furthermore, showed that the rodent pathogen Chlamydia muridarum blocks ubiquitination of its inclusions by interfering with mouse IRG function...

INTRODUCTION: Laparoscopic or robotic-assisted laparoscopic radical prostatectomy (RALP) is a frequently used approach for localized carcinoma prostate. For intermediate and high-risk cancers, extended pelvic lymph node dissection (e-PLND), is often performed. Conventional e-PLND involves piecemeal retrieval of lymphatic tissue. We describe a novel technique of laparoscopic e-PLND, which involves en-masse removal of pelvic lymph nodes from each side, based on an overlying peritoneal scaffold...

Limb reduction and loss are hallmarks of snake evolution. Although advanced snakes are completely limbless, basal and intermediate snakes retain pelvic girdles and small rudiments of the femur. Moreover, legs may have re-emerged in extinct snake lineages [1-5], suggesting that the mechanisms of limb development were not completely lost in snakes. Here we report that hindlimb development arrests in python embryos as a result of mutations that abolish essential transcription factor binding sites in the limb-specific enhancer of Sonic hedgehog (SHH)...

Pelvic organ prolapse (POP) is a common multifactorial condition. Matrix metalloproteinases (MMPs) are enzymes capable of breaking down various connective tissue elements. Single-nucleotide polymorphisms (SNPs) in regulatory areas of MMP-encoding genes can alter their transcription rate, and therefore the possible effect on pelvic floor supporting structures. The insertion of an adenine (A) base in the promoter of the MMP-3 gene at position -1612/-1617 produces a sequence of six adenines (6A), whereas the other allele has five (5A)...

BACKGROUND: About 10% of women of reproductive age suffer from endometriosis, a costly chronic disease causing pelvic pain and subfertility. Laparoscopy is the gold standard diagnostic test for endometriosis, but is expensive and carries surgical risks. Currently, there are no non-invasive tests available in clinical practice to accurately diagnose endometriosis. This review assessed the diagnostic accuracy of combinations of different non-invasive testing modalities for endometriosis and provided a summary of all the reviews in the non-invasive tests for endometriosis series...
