Anticoagulation Protocol for Secondary Prevention of Acute Ischemic Stroke Associated with Nonvalvular Atrial Fibrillation.

Objectives: There is no clear evidence regarding when to initiate oral anticoagulants (OACs) for secondary prevention of recurrent stroke in patients with atrial fibrillation (AF). Therefore, this study aimed to evaluate the safety and efficacy of a novel OAC initiation protocol for secondary prevention of acute ischemic stroke associated with AF.

Materials And Methods: In this multicenter prospective study 597 consecutive Japanese patients with acute ischemic stroke associated with nonvalvular AF received post-stroke OACs according to a protocol based on severity (clinical (NIHSS) and radiological (ASPECTS + W)), rt-PA use, reperfusion, and hemorrhagic transformation (HT).

Preoperative Predictive Factors of Short-Term Outcome in Idiopathic Normal Pressure Hydrocephalus.

Background: Surgical treatment of idiopathic normal pressure hydrocephalus (iNPH) by ventriculoperitoneal (VP) or lumboperitoneal (LP) shunting can achieve long-term recovery of activities of daily living; however, in a subset of patients, maintenance of independence lasted for <6 months. This study examined positive preoperative predictive factors of short-term outcome for shunted iNPH patients.

Methods: Over a 9-year period, consecutive patients from multiple centers diagnosed with probable iNPH underwent either VP or LP shunt surgery.

Detailed standardized protocol to prevent cerebrospinal fluid shunt infection.

Objective: While cerebrospinal fluid (CSF) shunt surgery plays an essential role in the treatment of hydrocephalus, postoperative infection due to the implantation of foreign materials is still one of the most common and potentially serious complications of this procedure. Because no previously reported protocol has been proven to prevent postoperative infection after CSF shunt surgeries in adults, the authors investigated the effectiveness of a protocol introduced in their institution.

Methods: A detailed standardized surgical protocol to prevent infection in patients undergoing CSF shunt surgeries was introduced in the authors' institution in December 2011.

Luteinizing Hormone Facilitates Antral Follicular Maturation and Survival via Thecal Paracrine Signaling in Cattle.

LH supplementation in assisted reproductive technology cycles improves the ongoing pregnancy rate in women with poor ovarian response (POR). However, our knowledge of the precise role of LH during the follicular phase of the menstrual cycle is incomplete. To explore the role of LH in the maturation of small antral follicles, we used an in vitro two-cell system that involved coculturing bovine granulosa cells (GCs) and theca cells (TCs) on a collagen membrane.

Clinical significance of atypical squamous cells of undetermined significance after treatment for cervical intraepithelial grade 3 neoplasia: A retrospective single-center cohort study.

The aim of the present study was to evaluate the clinical significance of atypical squamous cells of undetermined significance (ASC-US) following cervical conization for cervical intraepithelial neoplasia (CIN) grade 3. This study was a retrospective cohort analysis. The medical records of women treated with conization for CIN 2-3 were reviewed and 142 patients with CIN 3 who had been diagnosed using the conization specimens were selected.

Ultra-Early Combination Antiplatelet Therapy with Cilostazol for the Prevention of Branch Atheromatous Disease: A Multicenter Prospective Study.

Background And Purpose: The optimal use of antiplatelet therapy for intracranial branch atheromatous disease (BAD) is not known.

Methods: We conducted a prospective multicenter, single-group trial of 144 consecutive patients diagnosed with probable BAD. All patients were treated within 12 h of symptom onset to prevent clinical progression using dual antiplatelet therapy with cilostazol plus one oral antiplatelet drug (aspirin or clopidogrel).

Protective effect of dienogest on chemotherapy-induced reduced fertility in female rats.

Reduced fertility is one of the main long-term consequences of chemotherapy given for lymphoma, leukemia, and other malignancies in young women. We examined with a female rat model whether and how dienogest, a fourth-generation progestin, modulates reduced fertility following exposure to gonadotoxic chemotherapy. Female rats were administered cyclophosphamide with or without GnRH agonist and different concentrations of dienogest for 20 days.

Abrogation of CC chemokine receptor 9 ameliorates collagen-induced arthritis of mice.

Introduction: Biological drugs are effective in patients with rheumatoid arthritis (RA), but increase severe infections. The CC chemokine receptor (CCR) 9 antagonist was effective for Crohn's disease without critical adverse effects including infections in clinical trials. The present study was carried out to explore the pathogenic roles of chemokine (C-C motif) ligand (CCL) 25 and its receptor, CCR9, in autoimmune arthritis and to study if the CCR9 antagonist could be a new treatment for RA.

Cannabinoid receptor 2 as a potential therapeutic target in rheumatoid arthritis.

Background: Some of cannabinoids, which are chemical compounds contained in marijuana, are immunosuppressive. One of the receptors, CB receptor 1 (CB1), is expressed predominantly by the cells in the central nervous system, whereas CB receptor 2 (CB(2)) is expressed primarily by immune cells. Theoretically, selective CB(2) agonists should be devoid of psychoactive effects.

Recurrent mitral valve regurgitation with neutrophil infiltration in a patient with multiple aseptic abscesses.

Aseptic abscess (AA) is characterized by accumulation of neutrophils without evidence of infection, no response to antibiotics, and rapid response to corticosteroids. We report a case of multiple abscesses in the subcutaneous tissues and joints, and severe mitral valve regurgitation. Although AA did not respond to antibiotic therapy, it improved dramatically with corticosteroid treatment.

Dysregulation of ovarian follicular development in female rat: LH decreases FSH sensitivity during preantral-early antral transition.

Several clinical studies have shown a correlation of hypersecretion of LH and polycystic ovary syndrome (PCOS), infertility, and miscarriage in women, suggesting that chronically elevated LH impairs fertility. Growth arrest of small antral follicles in PCOS is also assumed to be associated with an abnormal endocrine environment involving increased LH stimulation, a hyperandrogenic milieu, and subsequent dysregulated FSH action in the ovarian follicles. In this study, we examined whether and how LH modulates follicular development and steroid production during preantral-early antral follicle transition by using a rat preantral follicle culture system.

Necessity of lysophosphatidic acid receptor 1 for development of arthritis.

Objective: Lysophosphatidic acid (LPA) is a bioactive lipid that binds to a group of cell surface G protein-coupled receptors (LPA receptors 1-6 [LPA1-6 ]) and has been implicated as an important mediator of angiogenesis, inflammation, and cancer growth. This study was undertaken to analyze the effects of LPA1 on the development of arthritis.

Methods: Expression of LPA receptors on synovial tissue was analyzed by immunohistochemistry and quantitative reverse transcription-polymerase chain reaction.

Chemerin activates fibroblast-like synoviocytes in patients with rheumatoid arthritis.

Introduction: Chemerin is a chemotactic agonist identified as a ligand for ChemR23 that is expressed on macrophages and dendritic cells (DCs). In this study, we analyzed the expression of chemerin and ChemR23 in the synovium of rheumatoid arthritis (RA) patients and the stimulatory effects of chemerin on fibroblast-like synoviocytes (FLSs) from RA patients.

Methods: Chemerin and ChemR23 expression in the RA synovium was ascertained by immunohistochemistry and Western blot analysis.

Luteinizing hormone-induced Akt phosphorylation and androgen production are modulated by MAP Kinase in bovine theca cells.

Background: Theca cells play an important role in controlling ovarian steroidogenesis by providing aromatizable androgens for granulosa cell estrogen biosynthesis. Although it is well established that the steroidogenic activity of theca cells is mainly regulated by LH, the intracellular signal transduction mechanisms that regulate thecal proliferation and/or steroidogenesis remain obscure. In this study, we examined whether and how LH controls the PI3K/Akt signaling pathway and androgen production in bovine theca cells.

[Chronic spinal subdural hematoma associated with chronic intracranial subdural hematoma: a case report].

A 65-year-old woman presented with chronic spinal subdural hematoma (CSSH) associated with intracranial chronic subdural hematoma (CSH), manifesting as pain in the bilateral buttocks and posterior thighs. She had fallen and struck her lumbar region and occiput while walking 2 weeks previously. Neurological examination on admission demonstrated no paresis of the lower extremities.

A comparison of uterine peristalsis in women with normal uteri and uterine leiomyoma by cine magnetic resonance imaging.

Objective: The non-pregnant uterus shows wave-like activity (uterine peristalsis). This pilot study was intended to determine: (1) whether uterine peristalsis during the menstrual cycle is detectable by cine magnetic resonance imaging (MRI); (2) the effects of leiomyoma on uterine peristalsis.

Study Design: Mid-sagittal MRI was performed sequentially with T2-weighted single-shot fast spin-echo (SSFSE) in 3 normal ovulatory volunteers and 19 premenopausal women with uterine leiomyoma.

Granulosa cells promote differentiation of cortical stromal cells into theca cells in the bovine ovary.

Formation of a theca cell (TC) layer is an important physiologic event that occurs during early follicular development. Nevertheless, little is known concerning the nature and regulation of the formation of the TC layer during follicular growth. Using an established coculture system in this study, we examined the hypothesis that stromal cells differentiate into TCs during early follicular development and that this process involves interaction with granulosa cells (GCs).

Luteinizing hormone-induced extracellular-signal regulated kinase activation differently modulates progesterone and androstenedione production in bovine theca cells.

It has been reported that gonadotropins promoted phosphorylation of ERK/MAPK in granulosa cells. However, little is known about the effects of gonadotropin on ERK activity in theca cells. This study explores how LH/forskolin controls ERK phosphorylation in cultured bovine theca cells.
