T-cell lymphoma (TCL) is a group of heterogeneous disorders with a poor response to conventional treatment. In order to identify novel therapeutic targets, the present study investigated the effect of leptin and its receptor on glucose metabolism in TCL. The expression of the leptin receptor (ObR), and glucose transporter (Glut)1 and 4 was detected in TCL and reactive lymphoid hyperplasia (RLH) tissues by immunohistochemical analysis. A higher level of ObR expression was observed in the TCL tissues than in the RLH tissues (58...

Menopur® is a highly purified, urine-derived, human menopausal gonadotropin containing both follicle stimulating hormone (FSH) and luteinizing hormone (LH) activity. It is an effective option for controlled ovarian stimulation (COS) in assisted reproductive technology protocols and for ovulation induction (OI) in anovulatory infertility, and is associated with a different endocrine profile from that of recombinant (r) FSH in these settings (in terms of serum levels of FSH, androgens and/or estradiol). When used for COS in women undergoing in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI), Menopur® was as good as rFSH in terms of pregnancy rates (despite being associated with a lower oocyte yield) and was found to improve some aspects of embryo quality in the IVF (but not ICSI) setting; using Menopur® in combination with highly purified urinary FSH resulted in similar reproductive outcomes as Menopur® alone...

Introduction: Reactive lymphoid hyperplasia (RLH) is a rare and benign lesion found in organs of the gastrointestinal tract, skin, lung, orbit, and more rarely in the liver. Due to its similar appearance on imaging, it is hard to differentiate from primary liver malignancies. The following is a case report of a patient presenting with a suspicious liver lesion found to be RLH associated with primary biliary cirrhosis (PBC), after surgical resection. Presentation of Case: A 54-year-old woman presented with nonspecific abdominal pain, and her workup included axial imaging of the abdomen that showed a suspicious lesion in her liver...

BACKGROUND: The association of recombinant FSH plus recombinant LH in 2:1 ratio may be used not only to induce ovulation in anovulatory women with hypogonadotropic hypogonadism but also to achieve multiple follicular developments in human IVF. The aim of this analysis was to estimate the cost-effectiveness of Controlled Ovarian Stimulation (COS) with recombinant FSH (rFSH) plus recombinant LH (rLH) in comparison with highly purified human menopausal gonadotropin (HP-hMG) in the woman undergoing in vitro fertilization (IVF) in Italy...

Consecutive treatments with recombinant follicle-stimulating and luteinizing hormones (rFsh and rLh, respectively) stimulate spermatogenesis and potentiate sperm production in pubescent specimens of the oligospermic Senegalese sole (Solea senegalensis). However, sperm production in response to the hormones is highly variable, and the steroidogenic potential of the testis may be diminished due to sustained hormone supply. Here, we compared the effectiveness of low (9 μg/kg) and high (18 μg/kg) doses of rFsh and rLh to improve sperm production in adult sole during late winter-early spring (onset of the natural spawning period), and in autumn under a controlled temperature of 12 °C (period of testicular recrudescence)...

Raloxifene hydrochloride (RLH) was formulated into a pH-modified supersaturatable self-microemulsifying drug delivery system (S-SMEDDS) to increase drug solubility and dissolution rate. Optimal formulations of pH-modified S-SMEDDSs were developed by incorporating hydroxypropyl-cellulose-L as a precipitation inhibitor and phosphoric acid as a pH modifier (an acidifier). RLH was dissolved to greater extents by all pH-modified S-SMEDDSs compared with non-pH-modified S-SMEDDSs. In particular, phosphoric acid afforded greater drug dissolution than did the other acidifiers tested, perhaps because phosphoric acid better controlled the pH...

BACKGROUND: Enlarged lymph nodes in adult patients often present a diagnostic challenge. In the absence of granuloma or necrosis, the cytology/tissue findings are misleading and relate the enlarged lymph nodes to reactive lymphoid hyperplasia (RLH), because granuloma formation is an immunological response that usually takes 14-100 days to develop. This study assesses the role of real-time (RT)-PCR in the diagnosis of the Mycobacterium complex (MTBC) in lymph node aspirates compared with culture in cases of RLH...

The aim of this study was to analyze eyebrow shapes in portraits of Chinese empresses of Ming and Qing dynasties.The frontal portraits of 20 Ming empresses and 24 of Qing in which the eye and eyebrows were identifiable were measured and analyzed. The arch shape did not differ significantly (P > 0.05) between Ming and Qing. The head-up type (66.6%) was significantly more common (P < 0.001), than tail-up (13.6%), horizontal (13.6%), and arched (6.8%). The brow arches of Ming and Qing empresses were classified as 5 arch types: L (Lamas), A (Anastasia), H (Hwang), M (Empress Ma), and D (Empress Du)...

RATIONALE: Conjunctival lymphoproliferative lesions constitute a significant diagnostic challenge and it is essential to exclude neoplastic lesions. Histopathological and immunohistochemical tests are very useful in establishing the correct diagnosis. Reactive lymphoid hyperplasia (RLH) is part of a spectrum of lymphocytic infiltrative disorders. Evidence is scarce regarding appropriate treatment of conjunctival RLH. We report a case treated with topical corticosteroid. PATIENT CONCERNS: A 40 year-old female presented with a 7-month history of a slow growth tumor in the superior conjunctiva of the right eye...

Two gonadotropins, follicle stimulating hormone (FSH) and luteinizing hormone (LH), are important players in the hypothalamic-pituitary-gonadal axis of vertebrates. In the present work, we describe the construction of recombinant (r) common carp (Cyprinus carpio; c) FSH (rcFSH) and LH (rcLH) using the Pichia pastoris system, the generation of specific antibodies against their respective β subunits, and their use in the development and validation of specific ELISAs. We produced carp rLH and rFSH as single-chain polypeptides, wherein the GTH subunit α was joined with either cLHβ or cFSHβ mature protein-coding sequences to form a fusion gene that encodes a yoked polypeptide, in which the GTH β-subunit forms the N-terminal part and the α-subunit forms the C-terminal part...

Innate immune system dysfunction has been known to be a key player in preeclampsia (PE). Activation of the maternal innate immunity may be triggered by invading microorganisms or endogenous ligands, which are detected by different pattern recognition receptors (PRRs). Although some studies have linked PRR activation to PE, it is still unclear if dysregulated PRR expression is associated with the development of this complication. Therefore, we conducted a systematic review of the literature, searching articles that evaluated associations of PRRs with PE...

Equine chorionic gonadotropin (eCG) is a unique molecule that elicits the response characteristics of both follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in other species. Previous studies from this laboratory had demonstrated that recombinant eCG (rec-eCG) from Chinese hamster ovary (CHO-K1) cells exhibited both FSH- and LH-like activity in rat granulosa and Leydig cells. In this study, we analyzed receptor internalization through rec-eCGs, wild type eCG (eCGβ/α) and mutant eCG (eCGβ/αΔ56) with an N-linked oligosaccharide at Asn(56) of the α-subunit...

The retinoic acid-inducible gene-I (RIG-I)-like helicases (RLH)s are cytoplasmic pattern recognition receptors expressed in both immune and non-immune cells that are essential for detection of intracellular RNA products, primarily of viral origin. Upon binding to viral RNA, RLHs interact with mitochondrial antiviral signaling protein (MAVS) to activate interferon (IFN)-mediated antiviral responses. The RLH/MAVS signaling pathway is regulated by ubiquitination/deubiquitination, in which several ubiquitin-editing proteins play critical roles...

BACKGROUND: One of the various ovarian stimulation regimens used for in-vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) cycles is the use of recombinant follicle-stimulating hormone (rFSH) in combination with a gonadotrophin-releasing hormone (GnRH) analogue. GnRH analogues prevent premature luteinizing hormone (LH) surges. Since they deprive the growing follicles of LH, the question arises as to whether supplementation with recombinant LH (rLH) would increase live birth rates...

Hormonal regulation of the expression of Mmp15, a proteolytic enzyme indispensable for ovulation in the teleost medaka, was investigated. In an in vitro culture system using preovulatory follicles, Mmp15 expression and ovulation were induced in the presence of recombinant luteinizing hormone (rLh). Both rLh-induced Mmp15 expression and ovulation were 17α, 20β-dihydroxy-4-pregnen-3-one-dependent, suggesting the involvement of a nuclear progestin receptor (Pgr). In vitro follicle ovulation and Mmp15 expression were reduced by treatment with the Pgr antagonist RU-486...
