TL;DR: This Review focuses on 'crosstalk manipulation' — the microbial strategies that instigate, subvert or disrupt the molecular signalling crosstalks between receptors of the innate immune system.
Abstract: In the arms race of host-microbe co-evolution, successful microbial pathogens have evolved ingenious ways to evade host immune responses. In this Review, we focus on 'crosstalk manipulation' - the microbial strategies that instigate, subvert or disrupt the molecular signalling crosstalk between receptors of the innate immune system. This proactive interference undermines host defences and contributes to microbial adaptive fitness and persistent infections. Understanding how pathogens exploit host receptor crosstalk mechanisms and infiltrate the host signalling network is essential for developing interventions to redirect the host response and achieve protective immunity.

TL;DR: The results suggest that while males and females may regulate their intake of nicotine similarly under limited access conditions, the motivation to obtain nicotine is higher in females.
Abstract: Rationale: Research on smoking behavior and responsiveness to nicotine suggests that nicotine's effects may depend on the sex of the organism. Objective: The present study addressed four questions: 1) Will female rats self-administer nicotine? 2) Does self-administration by females vary as a function of estrous cycle? 3) Does self-administration by females differ from that of males? 4) Does self-administration of nicotine result in up-regulation of nicotinic receptor binding and are these changes similar in males and females? Methods: Male and female Sprague-Dawley rats were allowed to self-administer nicotine at one of four doses (0.02–0.09 mg/kg, free base) on both fixed and progressive ratio schedules of reinforcement. Results: Females acquired nicotine self-administration across the entire range of doses. Acquisition of self-administration at the lowest dose was faster in females than males. However, few sex differences were found in the number of active responses, number of infusions, or total intake of nicotine during stable fixed ratio self-administration. In contrast, females reached higher break points on a progressive ratio. For both schedules, females had shorter latencies to earn their first infusion of each session and demonstrated higher rates of both inactive and timeout responding. There was no effect of estrous cycle on self-administration during either fixed or progressive ratio sessions. Self-administered nicotine resulted in average arterial plasma nicotine levels between 53 and 193 ng/ml and left hemi-brain levels between 174 and 655 ng/g, depending on dose. Nicotine self-administration produced similar up-regulation of nicotinic receptor binding sites in males and females, as reflected by increased right hemi-brain binding of [3H]-epibatidine, when compared to the brains of untreated control rats. Conclusions: These results suggest that while males and females may regulate their intake of nicotine similarly under limited access conditions, the motivation to obtain nicotine is higher in females.

TL;DR: In this article, the authors obtained reference values for the nerve cross-sectional area at the following sites: radial at antecubital fossa; radial at distal spiral groove; musculocutaneous in upper arm; trunks of the brachial plexus; vagus at carotid bifurcation; sciatic in distal thigh; tibial in popliteal fissure; tibia in proximal calf; tiberial at proximal ankle; peroneal in Popliteal Fissure 6; and sur
Abstract: Ultrasound allows for a non-invasive structural assessment of nerves, muscles, and surrounding tissues, and therefore it is increasingly being used as a supplement to traditional electrodiagnostic studies. As investigators have begun to use ultrasound to explore peripheral nerves, it has become clear that conditions such as entrapment, hereditary neuropathies, acquired neuropathies, trauma, and nerve tumors result in an increase in nerve cross-sectional area. Reference values have not been published for the cross-sectional area of many nerves commonly studied in diseases of the peripheral nervous system, so our goal was to obtain reference values for the nerve cross-sectional area at the following sites: radial at antecubital fossa; radial at distal spiral groove; musculocutaneous in upper arm; trunks of the brachial plexus; vagus at carotid bifurcation; sciatic in distal thigh; tibial in popliteal fossa; tibial in proximal calf; tibial at ankle; peroneal in popliteal fossa; peroneal at fibular head; and sural in distal calf. Mean cross-sectional area, as well as side-to-side differences, are reported for each site, and qualitative data are provided to guide imaging at each site. The information provided in this study should serve as the starting point for quantitatively evaluating these nerve sites with ultrasound.

TL;DR: In this article, a genetic blood disorder, Diamond-Blackfan anemia (DBA), where the majority of mutations affect ribosomal proteins and the erythroid lineage is selectively perturbed, was studied and mechanistic insight into how lineage commitment is programmed normally and disrupted in disease.
