The selective serotonin reuptake inhibitor fluoxetine has been used for the treatment of depression. Although sexual disorders have been reported in male patients, few studies have demonstrated the fluoxetine effect on the reproductive histophysiology, and the target of this antidepressant in testes is unknown. We evaluated the impact of short-term treatment with fluoxetine on the adult rat testes, focusing on steroidogenesis by Leydig cells (LC) and androgen-dependent testicular parameters, including Sertoli cells (SC) and peritubular myoid cells (PMC).

Aim: To demonstrate that a novel resting state BOLD ALFF (the amplitude of low-frequency fluctuation)-based correction method can substantially enhance the detectability of motor task activation in the presence of tumor-induced neurovascular uncoupling (NVU).
Methods: Twelve de novo brain tumor patients who underwent comprehensive clinical BOLD fMRI exams including task fMRI and resting state fMRI (rsfMRI) were evaluated. Each patient displayed decreased/absent task fMRI activation in the primary ipsilesional primary motor cortex in the absence of corresponding motor deficit or suboptimal task performance, consistent with NVU.

Thyroid transcription factor-1 (TTF-1) is overexpressed in up to 95% of primary lung adenocarcinoma while negative for almost all squamous cell carcinomas. TTF-1 expression has been investigated as a prognostic factor in non-small-cell lung cancer (NSCLC) with conflicting results. We conducted this meta-analysis to gain a better insight into the prognostic role of TTF-1 in patients only with non-squamous (non-SQ) NSCLC. Read More

Invasive aspergillosis is a common fungal infection in immunocompromised individuals. Some studies have shown that toll-like receptor and dectin-1 genetic polymorphisms may alter signaling pathways, thus increasing an individual's susceptibility to invasive aspergillosis. We investigated the pertinent literature to determine whether polymorphisms in the genes encoding toll-like receptors and dectin-1 increase the susceptibility to invasive aspergillosis. Read More

The ambient air of the Monterrey Metropolitan Area in Mexico frequently exhibits high levels of PM and PM. However, no information exists on the chemical composition of coarse particles (PM = PM - PM). A monitoring campaign was conducted during the summer of 2015, during which 24-hour average PM and PM samples were collected using high volume filter-based instruments to chemically characterize the fine and coarse fraction of the PM.

However, obtaining high quality images, at high magnification, is crucial for critical dimension and patterned feature evaluation. Therefore, in this work, we present a new sample preparation method for high performance cross-sectional secondary electron (SE) imaging, targeting features at the deep nanoscale and into the sub-10 nm regime.

Survivors of chronic life-threatening conditions like myocardial infarction (MI) are often confronted with multiple physical and psychological stressors as a consequence of elevated demands of lifestyle adjustments and modifications. Such stressors, collectively known as "life chaos", cause disruption to one's lifestyle equilibrium of having organized, calm, and regular routines. The objective of the current study was to determine the level of life chaos and its associated correlates among post-myocardial infarction (post-MI) survivors in Malaysia. Read More

This paper investigated the effects of cognitive and motor dual tasks on gait performance and brain activities in stroke; 23 stroke subjects performed single walking (SW), walking while performing cognitive task (WCT), and walking while performing motor task (WMT) at self-selected speed. The gait performance was recorded, including speed, cadence, stride time, stride length, and dual task cost (DTC). Brain activities in prefrontal cortex, premotor cortex (PMC), and supplementary motor areas (SMAs) were measured by functional near-infrared spectroscopy during walking. Read More

It is common knowledge that dysfunction of the immune and neuroendocrine systems, in addition to neuroplasticity, is among the pathways that underlie irritable bowel syndrome (IBS) and depression. From as early as the 1950s, the association of IBS with psychiatric disease was postulated; however, the exact mechanism remains elusive. There has been considerable research into the association of IBS and depression over the last years; research into the gut-brain axis and alterations in gut microbes have gained momentum to spell out the relationship between depression and IBS.

The impact of peroxide surface treatment on the resistive switching characteristics of zinc peroxide (ZnO)-based programmable metallization cell (PMC) devices is investigated. The peroxide treatment results in a ZnO hexagonal to ZnO cubic phase transformation; however, an excessive treatment results in crystalline decomposition. The chemically synthesized ZnO promotes the occurrence of switching behavior in Cu/ZnO/ZnO/ITO with much lower operation current as compared to the Cu/ZnO/ITO (control device). Read More

Background: Extremely high temperatures are becoming an increasingly severe threat to crop yields. It is well documented that salicylic acid (SA) can enhance the stress tolerance of plants; however, its effect on the reproductive organs of rice plants has not been described before. To investigate the mechanism underlying the SA-mediated alleviation of the heat stress damage to rice pollen viability, a susceptible cultivar (Changyou1) was treated with SA at the pollen mother cell (PMC) meiosis stage and then subjected to heat stress of 40 °C for 10 d until 1d before flowering.

Objectives: Traditional targeting methods for thalamic deep brain stimulation (DBS) performed to address tremor have predominantly relied on indirect atlas-based methods that focus on the ventral intermediate nucleus despite known variability in thalamic functional anatomy. Improvements in preoperative targeting may help maximize outcomes and reduce thalamic DBS-related complications. In this study, we evaluated the ability of thalamic parcellation with structural connectivity-based segmentation (SCBS) to predict tremor improvement following thalamic DBS. Read More

Aim: To evaluate, via clinical and radiographic assessment; the success of calcium hydroxide pulpotomies with the application of 5% sodium hypochlorite as a haemostatic agent compared with physiologic saline in primary molars and to evaluate if there is improved efficacy of increased concentration of sodium hypochlorite application in calcium hydroxide pulpotomies.
Methods: Thirty children aged between 3 and 8 years, having at least two vital primary molars (split mouth design) with deep carious lesions with probable exposure of the pulp, were selected. The 60 teeth were randomly allocated to two groups and conventional calcium hydroxide pulpotomies were performed on all selected primary molars in both the groups. Read More

Purpose: Recent literature has shown the potential of high-resolution quantitative susceptibility mapping (QSM) with ultra-high field MRI for imaging the anatomy, the vasculature, and investigating their magnetostatic properties. Higher spatial resolutions, however, translate to longer scans resulting, therefore, in higher vulnerability to, and likelihood of, subject movement. We propose a gradient-recalled echo sequence with prospective motion correction (PMC) to address such limitation. Read More

Over the last three decades, allogeneic haematopoietic stem cell transplantation (HSCT) has become an important therapeutic tool that can cure life-threatening diseases affecting children and adults, including a variety of neoplastic and inborn genetic disorders of the hematopoietic system. Engraftment of donor-derived cells represents a crucial event in order to obtain a successful transplant; therefore, many techniques have been developed to monitor engraftment and eventually determine the presence of mixed chimerism (MC) after HSCT. PCR based on the amplification of short tandem repeats (STR) is currently the most common technique used to monitor chimerism, although the degree of achievable quantification can be increased by performing quantitative PCR.

Reach movements are characterized by multiple kinematic variables that can change with age or due to medical conditions such as movement disorders. While the neural control of reach direction is well investigated, the elements of the neural network regulating speed (the nondirectional component of velocity) remain uncertain. Here, we used a custom made magnetic resonance (MR)-compatible arm movement tracking system to capture the real kinematics of the arm movements while measuring brain activation with functional magnetic resonance imaging to reveal areas in the human brain in which BOLD-activation covaries with the speed of arm movements.
