Trastuzumab is a milestone in the treatment of human epidermal growth factor receptor 2 positive (HER2+) breast cancer (BC), in both the early and metastatic settings. Over the last two decades, clinical trials have established the good safety profile of trastuzumab. Cardiotoxicity remains the most frequent adverse event, more commonly exemplified by an asymptomatic decline in the left ventricular ejection fraction rather than congestive heart failure. Results from several long-term (>5 years) safety analyses have been recently published, with the inherent evidence substantially confirming the findings from previous trials...

This study investigated relationships between shorter (505, change-of-direction (COD) deficit as a derived physical quality) and longer (Illinois agility test; IAT) COD tests with linear speed, lower-body power (multidirectional jumping), and strength in recreationally-trained individuals. Twenty-one males and 22 females (similar to collegiate club-sport and tactical athletes) were assessed in: 505 and COD deficit from each leg; IAT; 20 m sprint; vertical jump (VJ height, peak anaerobic power measured in watts (PAPw), power-to-body mass ratio); standing broad jump; lateral jump (LJ) from each leg; and absolute and relative isometric midthigh pull (IMTP) strength...

River channel confluences are widespread in natural rivers. Understanding their unique hydrodynamic characteristics and contaminant transport rules may facilitate the rational and effective treatment of the water environment. In this study, we considered the Xitiaoxi River Basin as the research area, and a well-designed flume was established based on the extracted water system features. Hydrodynamically, in the Y-shaped confluence channel the flow velocity was easy to separate at the confluence, and a low flow velocity region appeared in the two branches...

Perceptual and behavioral asymmetry has been observed in a wide range of vertebrate and invertebrate species with its origin estimated to go back over 500 million years. Previously, hemispheric lateralization in marine mammals has been recorded during foraging, parental care, preferred swimming direction as well as when solving cognitive challenges. Visual laterality has been demonstrated in preferred eye use and performance accuracy. A female Indo-Pacific bottlenose dolphin was trained to associate eight pairs of non-identical visual stimuli...

Despite the use of reperfusion therapies in the last decades, acute myocardial infarction further remains one of the most frequent causes of mortality. This is mainly caused by changes in the ventricular architecture leading to ventricular remodeling, followed by progressive development of heart failure. Transthoracic echocardiography is a non-invasive instrument which can provide information about the extent of the ischemic process and its consequences but can also predict the outcomes after myocardial infarction...

PURPOSE: To examine human mandibular angle integrity alterations accompanying a mandibular body block graft harvest surgical procedure. MATERIALS AND METHODS: Hemimandibles from 24 human cadavers were resected and sorted into one of three groups by residual dental status. The height of each hemimandible body was obtained and recorded. Acrylic bone cement was utilized to mount the hemimandibles at the mandibular condyle. Using standard surgical instruments and techniques, cortical bone of the mandibular body buccal plate was resected from the right hemimandibles...

OBJECTIVES: Less than half of the thousands of children who suffer in-hospital cardiac arrests annually survive, and neurologic injury is common among survivors. Hemodynamic-directed cardiopulmonary resuscitation improves short-term survival, but its impact on longer term survival and mitochondrial respiration-a potential neurotherapeutic target-remains unknown. The primary objectives of this study were to compare rates of 24-hour survival with favorable neurologic outcome after cardiac arrest treated with hemodynamic-directed cardiopulmonary resuscitation versus standard depth-guided cardiopulmonary resuscitation and to compare brain and heart mitochondrial respiration between groups 24 hours after resuscitation...

OBJECTIVE: Unilateral left varicoceles are common and considered benign. Unilateral right varicoceles are reportedly associated with a pathologic process, namely malignancy affecting the retroperitoneum, for which further imaging is often recommended. The purpose of this study was to test the hypothesis that this correlation between unilateral right varicocele and malignancy may be weaker than once suggested, particularly in the absence of other clinical signs of malignancy. MATERIALS AND METHODS: Medical charts and imaging at one institution were reviewed for all patients reported to have right varicocele...

BACKGROUND: Despite recent progress in profiling of risk for sudden cardiac death (SCD) and prevention and intervention of cardiac diseases, SCD remains a major cause of death. Among women, the incidence of SCD is significant, but lower than in men, particularly in the premenopausal and early postmenopausal years. Possibly, as a consequence of the difference in population burden, the mechanisms and risk markers of SCD are not as well defined for women. The aim of this study was to determine the autopsy findings and causes of death among women in a large SCD population...

Auditory cortex in each hemisphere shows preference to sounds from the opposite hemifield in the auditory space. Besides this contralateral dominance, the auditory cortex shows functional and structural lateralization, presumably influencing the features of subsequent auditory processing. Children have been shown to differ from adults in the hemispheric balance of activation in higher-order auditory based tasks. We studied, first, whether the contralateral dominance can be detected in 7- to 8-year-old children and, second, whether the response properties of auditory cortex in children differ between hemispheres...

BACKGROUND: Application of speckle-tracking echocardiography (STE) provides rapid assessment of tissue-tracking mitral annular displacement (TMAD). We investigated the value of TMAD for the assessment of decreased LV longitudinal deformation in asymptomatic patients with severe or moderate-to-severe mitral regurgitation (MR) and preserved LV ejection fraction (LVEF). METHODS: We retrospectively studied 50 patients with severe or moderate-to-severe organic MR and preserved LVEF (>60%) in whom global longitudinal strain (GLS) was successfully measured by STE...

Infectious haematopoietic necrosis (IHN) and viral haemorrhagic septicaemia (VHS) are OIE-listed and notifiable viral fish diseases which are controlled by eradication and surveillance programmes globally. The present study provides improved RT-qPCR procedures based on recently described OIE protocols. Improvements comprise the design of a new TaqMan® probe, replacing a TaqMan® MGB probe that turned out to show impaired binding. Reason for this is SNPs detected in the nucleoprotein N gene sequences of IHNV strains targeted by the RT-qPCR...
