The estrogen-synthesizing enzyme aromatase is abundant at the synapse in the zebra finch hippocampus (HP) and its inhibition impairs spatial memory function. To more fully test the role of local estradiol (E2) synthesis in memory, the HP of adult male zebra finches was exposed to either control pellets or those containing the aromatase inhibitor ATD, ATD and E2, ATD and the G protein-coupled estrogen receptor (GPER) agonist G1, or the antagonist G15 alone. Birds were tested for spatial memory acquisition and performance, and HP levels of the postsynaptic protein PSD95 were measured...

Differentiated vulvar intrapeithelial neoplasia (dVIN) is an human papillomavirus (HPV)-independent precursor of squamous cell carcinoma (SCC), and the aim of this study was to better characterize its natural history. Cases of dVIN were identified from the pathology archives. Outcomes of patients with dVIN only, without associated invasive SCC, were compared with a cohort of patients with high-grade squamous intraepithelial lesion [HSIL(VIN3)]. Eighteen patients diagnosed with dVIN with adjacent invasive SCC (SCC/dVIN) and 7 patients with dVIN only, without invasive carcinoma, were identified...

Ninety-five percent of precursor lesions -high-grade squamous intraepithelial lesions (HSIL) and anal intraepithelial neoplasms (AIN)- and their progression to squamous anal cancer (AC) are induced by high-risk HPV (HR-HPV) serotypes 16 and 18. Their incidence is higher particularly in HIV-infected male patients who have sex with other males (HIV-MSM) (144/100,000/patients/year).

Skin lesions in sarcoidosis are often the initial symptoms that enable the dermatologist to be the first to diagnose this granulomatosis. However, diagnosis is sometimes very problematic. In 2015, the diagnostic criteria for sarcoidosis were updated in Japan, with elevated serum soluble interleukin-2 receptor (sIL-2R) replacing negative tuberculin reaction. Therefore, we assessed the clinical utility of sIL-2R compared with two other common markers, angiotensin-converting enzyme (ACE) and lysozyme, in patients who visited the dermatology clinic...

The concept of genitourinary syndrome of menopause (GSM) was recently introduced and has been gaining widespread use. While some justifications for its introduction are straightforward, others may be questionable. Numerous unspecific symptoms and signs were included in the definition of the syndrome, but the minimum number required for diagnosis was not established. While the GSM definition is designed to facilitate identifying vulvovaginal and urinary estrogen-deprivation-associated symptoms and signs, several concerns have evolved: (1) the syndrome may result in the underdiagnosis of vulvar and urinary pathology; and (2) serious conditions (e...

Although aerobic CO dehydrogenases (CODHs) might be applicable in various fields, their practical applications have been hampered by low activity and no heterologous expression. We, for the first time, could functionally express recombinant PsCODH in E. coli and obtained a highly concentrated recombinant enzyme using an easy and convenient method. Its electron acceptor spectra, optimum conditions (pH 6.5 and 30 °C), and kinetic parameters (kcat of 12.97 s(-1), Km of 0.065 mM, and specific activity of 0...

Lesley J Scott
Sarilumab (Kevzara™) is a fully human IgG1 monoclonal antibody that binds specifically to both soluble and membrane-bound interleukin (IL)-6 receptors (sIL-6Rα and mIL-6Rα) and thereby inhibits IL-6-mediated signalling through these receptors. Subcutaneous sarilumab is approved in Canada for the treatment of adult patients with moderately to severely active rheumatoid arthritis who have had an inadequate response to one or more biological or non-biological disease-modifying anti-rheumatic drugs. It is under regulatory review for use in rheumatoid arthritis in other countries, including in the EU, USA and Japan...

Behçet's disease (BD) is a multi-systemic inflammatory disorder consisting of recurrent oral aphthosis, genital ulcers, and chronic relapsing bilateral uveitis; however, many other organs may be affected. Several pro-inflammatory cytokines, mainly derived from Th1 and Th17 lymphocytes, seem to be involved in different pathogenic pathways leading to development of the clinical manifestations. On this basis, the primary aim of our study was to compare a core set of pro-inflammatory cytokines between patients with BD and healthy control (HC)...

Repeated airway inflammation and unremitting remodeling provoke irreversible pulmonary dysfunction and resistance to current drugs in patients with chronic bronchial asthma. Interleukin (IL)-13 and IL-25 play an important role in airway inflammation and remodeling in asthma. We aimed to investigate whether co-inhibiting IL-13 and IL-25 can effectively down-regulate allergen-induced airway inflammation and remodeling in mice. Mice with asthma induced by chronic exposure to ovalbumin (OVA) were given soluble IL-13 receptor α2 (sIL-13R) or soluble IL-25 receptor (sIL-25R) protein alone and in combination to neutralize the bioactivity of IL-13 and IL-25, and relevant airway inflammation and remodeling experiments were performed...

Excessive influx and the subsequent rapid cytosolic elevation of Ca(2+) in neurons is the major cause to induce hyperexcitability and irreversible cell damage although it is an essential ion for cellular signalings. Therefore, most neurons exhibit several cellular mechanisms to homeostatically regulate cytosolic Ca(2+) level in normal as well as pathological conditions. Delayed rectifier K(+) channels (IDR channels) play a role to suppress membrane excitability by inducing K(+) outflow in various conditions, indicating their potential role in preventing pathogenic conditions and cell damage under Ca(2+)-mediated excitotoxic conditions...
