The properties of cell surface proteins targeted by Antibody-drug conjugates (ADCs) have not been fully exploited; of particular importance are the rate of internalization and the route of intracellular trafficking. In this study we compared the trafficking of HER2, which is the target of the clinically approved ADC ado-trastuzumab emtansine (T-DM1), with that of prolactin receptor (PRLR), another potential target in breast cancer. In contrast to HER2, we found that PRLR is rapidly and constitutively internalized, and traffics efficiently to lysosomes, where it is degraded...

REVIEW
Rehman Ata, Costin N Antonescu
Integrins are important regulators of cell survival, proliferation, adhesion and migration. Once activated, integrins establish a regulated link between the extracellular matrix and the cytoskeleton. Integrins have well-established functions in cancer, such as in controlling cell survival by engagement of many specific intracellular signaling pathways and in facilitating metastasis. Integrins and associated proteins are regulated by control of transcription, membrane traffic, and degradation, as well as by a number of post-translational modifications including glycosylation, allowing integrin function to be modulated to conform to various cellular needs and environmental conditions...

BACKGROUND: Metabolic acidosis is a common complication of chronic kidney disease; current guidelines recommend treatment with alkali if bicarbonate levels are lower than 22 mMol/L. In fact, recent studies have shown that an early administration of alkali reduces progression of CKD. The aim of the study is to evaluate the effect of fruit and vegetables to reduce the acid load in CKD. METHODS: We conducted a case-control study in 146 patients who received sodium bicarbonate...

INTRODUCTION: The number of children diagnosed with autism spectrum disorder (ASD) has been rapidly rising in the past decade. The etiology of this disorder, however, is largely unknown, although the environmental relative to the genetic contribution is substantial. We conducted a scoping review to comprehensively assess the current state of knowledge of the environmental factors present from preconception to early life associated with ASD, and to identify research gaps. METHODS: We searched electronic databases MEDLINE, PsycINFO and ERIC for articles on potential risk factors or protective factors from the physical and social environments associated with ASD and its subclassifications published between 1 January, 2003, and 12 July, 2013...

Global populations of rhinoceros have declined alarmingly, from about 500,000 at the beginning of the 20(th) century to 29,000 in 2016, largely due to an escalation of poaching for rhinoceros horn (Traffic 2016; Biggs et al. 2013). The current global rhino population is comprised of three Asian Species and two African species, the latter located in South Africa, Kenya, Tanzania, Namibia and Zimbabwe,. In Africa, the Southern white rhinoceros population is estimated at 20,700; and there are estimated to be around 4,885 black rhinoceros...

The kainate receptor (KAR), a subtype of glutamate receptor, mediates excitatory synaptic responses at a subset of glutamatergic synapses. However, the molecular mechanisms underlying the trafficking of its different subunits are poorly understood. Here we use the CA1 hippocampal pyramidal cell, which lacks KAR-mediated synaptic currents, as a null background to determine the minimal requirements for the extrasynaptic and synaptic expression of the GluK2 subunit. We find that the GluK2 receptor itself, in contrast to GluK1, traffics to the neuronal surface and synapse efficiently and the auxiliary subunits Neto1 and Neto2 caused no further enhancement of these two trafficking processes...

Candida spp. are the most common causes of fungemia. Rapid and accurate diagnostic methods are very important for appropriate management of candidemia. At present, blood culture is the essential diagnostic test despite it has a long detection time and low sensitivity rate. We aimed to investigate the ways to shorten the turnaround time from blood culture collection to final identification in candidemia. Sixty clinical bloodstream isolates of Candida were included and the Plus Aerobic/F, Peds Plus/F and Mycosis IC/F (MICF) bottles were used with BACTEC 9240 blood culture instrument...

On July 3, 2015, Nalini Nadkarni, a world-renowned ecologist who had been studying the biologic processes of ecosystem disturbance and recovery, sustained a catastrophic 50-foot free-fall from the top of the rainforest canopy to the forest floor at her remote field research site. She lost consciousness in shock and sustained life-threatening injuries. Her accompanying students hiked out, radio-called 911, and the Harborview Medical Center (Seattle) Medivac team arrived 4 hours later to rescue her. Her prognosis was extremely grim; her family gathered in anticipation of her death as she underwent four operations during her 10 days in the ICU...

Exposure to particulate matter (PM) air pollution has been associated with a range of adverse health outcomes, including cardiovascular disease hospitalizations and other clinical parameters. Determining which sources of PM, such as traffic or industry, are most associated with adverse health outcomes could help guide future recommendations aimed at reducing harmful pollution exposure for susceptible individuals. Information obtained from multisite studies, which is generally more precise than information from a single location, is critical to understanding how PM impacts health and to informing local strategies for reducing individual-level PM exposure...

Estimating time to contact (TTC) involves multiple sensory systems, including vision and audition. Previous findings suggested that the ratio of an object's instantaneous optical size/sound intensity to its instantaneous rate of change in optical size/sound intensity (τ) drives TTC judgments. Other evidence has shown that heuristic-based cues are used, including final optical size or final sound pressure level. Most previous studies have used decontextualized and unfamiliar stimuli (e.g., geometric shapes on a blank background)...
