Redox-type resistive random access memories (ReRAM) based on transition metal oxides are studied as adjustable two-terminal devices for integrated network applications beyond von Neumann computing. The prevailing, so-called, counter-eight-wise (c8w) polarity of the switching hysteresis in filamentary-type valence change mechanism (VCM) devices originates from a temperature and field controlled drift-diffusion process of mobile ions, predominantly oxygen vacancies in the switching oxide. Recently, a bipolar resistive switching (BRS) process with opposite polarity, so-called, eight-wise (8w) switching has been reported that, especially for TiO2 cells, is still not completely understood...

An 18-year-old virginal woman was referred to the reproductive endocrinology clinic with primary amenorrhoea and secondary sexual development in the absence of pelvic pain. Additionally, she had significant congenital sensorineural hearing loss, autism, bipolar disorder and class III obesity. On physical examination, secondary sexual development was confirmed (Tanner 5 breasts and Tanner 4 pubic hair). She refused further pelvic examination following prior attempts by the referring physicians. Serum leutinizing hormone (LH), follicle sitmulating hormone (FSH)...

We report on the investigation of the resistive switching (RS) in the ultrathin (≈5 nm in thickness) yttria-stabilized zirconia (YSZ) films with single layers of Au nanoparticles (NPs) by conductive atomic force microscopy (CAFM). Besides the butterfly-type hysteresis loops in the current-voltage ( I - V ) curves of the contact of the CAFM probe to the investigated film surface corresponding to the bipolar RS, the negative differential resistance (NDR) has been observed in the I - V curves of the AFM probe contact to the YSZ films with Au NPs in the conductive ("ON") state...

In this issue of the journal, 2 case reports are presented that illustrate explicit influences of structural brain lesions on psychiatric symptoms. In both cases, the patients had preexisting, classically diagnosed psychiatric disorders-schizophrenia in the first case and bipolar I disorder in the second case. In the first case, a 61-year-old woman with chronic paranoid schizophrenia experienced a marked reduction in psychotic symptoms after bilateral frontal strokes. In the second case, a 60-year-old man who had experienced manic and depressive episodes since his 20s developed partial complex seizures after having repeated head trauma in his 40s, with subsequent onset of chronic personality changes associated with temporal lobe epilepsy that made his psychiatric treatment a greater challenge...

Eotaxin-1/CCL11 is a chemokine originally implicated in the selective recruitment of eosinophils into inflammatory sites during allergic reactions, being thoroughly investigated in asthma, allergic rhinitis, and other eosinophil-related conditions. Eotaxin-1/CCL11 is also involved with a skewed immune response toward a type-2 (Th2) profile. In addition to its role in immune response, recent studies have shown that eotaxin-1/CCL11 is associated with aging, neurogenesis and neurodegeneration, being able to influence neural progenitor cells, and microglia...

Schizophrenia and bipolar disorder are severe and debilitating psychiatric disorders. Despite the availability of numerous antipsychotic drugs, many patients still experience poor outcomes and treatment-limiting adverse side effects. Cariprazine is a novel antipsychotic with unique pharmacodynamic and pharmacokinetic properties. It is both a dopamine type 2 and dopamine type 3 partial agonist with 2 equipotent metabolites, desmethyl cariprazine and didesmethyl cariprazine, of which didesmethyl cariprazine has a half-life of 1 to 3 weeks...

INTRODUCTION: Benign prostatic hyperplasia (BPH) is a non-cancerous enlargement of the prostate gland, which results in the development of lower urinary tract symptoms that can interfere with a patient's daily activities and negatively impact their quality of life. The gold standard treatment for moderate to severe BPH has been transurethral resection of the prostate (TURP), however, this procedure is associated with prolonged hospitalizations and increased complications. An alternative to TURP is Greenlight photoselective vaporization of the prostate (PVP), which is associated with better perioperative safety...

α2 δ-4 is an auxiliary subunit of voltage-gated Cav 1.4 L-type channels that regulate the development and mature exocytotic function of the photoreceptor ribbon synapse. In humans, mutations in the CACNA2D4 gene encoding α2 δ-4 cause heterogeneous forms of vision impairment in humans, the underlying pathogenic mechanisms of which remain unclear. To investigate the retinal function of α2 δ-4, we used genome editing to generate an α2 δ-4 knock-out (α2 δ-4 KO) mouse. In male and female α2 δ-4 KO mice, rod spherules lack ribbons and other synaptic hallmarks early in development...
