#1
Rami O Tadros, Vivek S Prakash, Melissa J Baldwin, Adam Korayem, Michael L Marin, Peter L Faries
Simultaneous technological advancements in both imaging as well as devices have resulted in an expansion of endovascular options for vascular access. In particular, radial access has traditionally been more favored for coronary interventions; its use in the aortoiliac and lower extremity vasculature has been constrained by the length of devices and the size of sheaths required. However, with increasing catheter shaft lengths, in addition to new thin-walled sheaths allowing for downsizing, the ability to perform transradial interventions on infrainguinal and infrageniculate vessels has been more readily facilitated...

Background: Studies on the implementation of antibiotic stewardship programs (ASPs) in small hospitals are limited. Accreditation organizations now require all hospitals to have ASPs. Methods: The objective of this cluster-randomized intervention was to assess the effectiveness of implementing ASPs in Intermountain Healthcare's 15 small hospitals. Each hospital was randomized to 1 of 3 ASPs of escalating intensity. Program 1 hospitals were provided basic antibiotic stewardship education and tools, access to an infectious disease hotline, and antibiotic utilization data...

Modern surgical approaches are becoming more minimalistic, associated with the term 'minimally invasive'. The endoscope provides a more panoramic anatomical view in addition to the ability to access narrow deep corners with decent illumination and clear visualization. Endoscopic assisted microsurgery through a tailored small craniotomy is the foundation of keyhole surgery. The endoscope can be advanced deeper into the field, thus enhancing an exposure and allowing bimanual dissection, thus prompting smaller craniotomies and tailored key exposures...

Actinomycetes have been proven to be an excellent source of secondary metabolites for more than half a century. Exhibiting various bioactivities, they provide valuable approved drugs in clinical use. Most microorganisms are still untapped in terms of their capacity to produce secondary metabolites, since only a small fraction can be cultured in the laboratory. Thus, improving cultivation techniques to extend the range of secondary metabolite producers accessible under laboratory conditions is an important first step in prospecting underexplored sources for the isolation of novel antibiotics...

To investigate the cyanylated cysteine vibrational probe group's ability to report on binding-induced changes along a protein-protein interface, the probe group was incorporated at several sites in a peptide of the calmodulin (CaM) binding domain of skeletal muscle myosin light chain kinase. Isothermal titration calorimetry was used to determine the binding thermodynamics between calmodulin and each peptide. For all probe positions, the binding affinity was nearly identical to that of the unlabeled peptide...

Genetically engineered mouse models (GEMMs) are extremely valuable in revealing novel biological insights into the initiation and progression mechanisms of human diseases such as cancer. Transgenic and conditional knockout mice have been frequently used for gene overexpression or ablation in specific tissues or cell types in vivo. However, generating germline mouse models can be time-consuming and costly. Recent advancements in gene editing technologies and the feasibility of delivering DNA plasmids by viral infection have enabled rapid generation of non-germline autochthonous mouse cancer models for several organs...

Over the past two decades, debate over the whys, the hows, and the effects of the ever-expanding phenomenon of right-to-health litigation ('judicialization') throughout Latin America have been marked by polarised arguments and limited information. In contrast to claims of judicialization as a positive or negative trend, less attention has been paid to ways to better understand the phenomenon in real time. In this article, we propose a new approach-Judicialization 2.0-that recognises judicialization as an integral part of democratic life...

REVIEW
Christina Stonoha-Arther, Dong Wang
The symbiosis formed by nitrogen-fixing bacteria with plant hosts mainly in the legume family involves a very intimate interaction. Within the symbiotic organ (the nodule) the bacteria are fully internalized by the host cell to become an intracellular organelle surrounded by a host-derived membrane. This arrangement is probably necessary for the efficient provision of energy and the sequestration of free oxygen molecules, two conditions required for sustained nitrogen fixation. Recent advances made in model legume species, such as Medicago truncatula, are beginning to uncover the genetic components allowing rhizobia to access the host cytoplasm and establish chronic intracellular infections without overt detrimental effects...
