The rapid growth in the number of behavior analysts and aspiring behavior analysts creates an imperative for effective and efficient supervisory practices. Many behavior analysts receive little to no explicit instruction and mentoring in supervision practices while they are in training themselves. Those behavior analysts may then be expected to provide supervision for a range of individuals soon after graduation and certification and throughout the remainder of their career. The papers included in this special issue offer guidance for establishing and maintaining supervisory relationships, understanding the importance of each of the ethical guidelines for supervision, structuring group supervision experiences, managing problems that can arise during the course of a supervisory relationship, and arranging models of supervision within human service organizations...

Ammonia-oxidizing bacteria (AOB), which oxidize ammonia to nitrite in the first step of nitrification, play an important role in biological wastewater treatment systems. Nitrosomonas mobilis is an important and dominant AOB in various wastewater treatment systems. However, the detailed physiological and genomic properties of N. mobilis have not been thoroughly investigated because of limited success isolating pure cultures. This study investigated the key physiological characteristics of N. mobilis Ms1, which was previously isolated into pure culture from the nitrifying granules of wastewater treatment bioreactor...

A 76-year-old man presented to our hospital with abdominal distention and loss of appetite. The 10% of weight lost relative to this patient in 1 month. Abdominal computed tomography and magnetic resonance imaging revealed a giant mass, with a major axis of 23 cm, containing solid components, not involving the upper abdominal organs. Esophagogastroduodenoscopy showed extramural compression from the middle gastric body to the antrum, as well as a normal mucosal surface. These findings were suggestive of a gastrointestinal stromal tumor attached to the anterior wall of the stomach without metastasis or invasion...

The complex anatomy of the skull and face arises from the requirement to support multiple sensory and structural functions. During embryonic development, the diverse component elements of the neuro- and viscerocranium must be generated independently and subsequently united in a manner that sustains and promotes the growth of the brain and sensory organs, while achieving a level of structural integrity necessary for the individual to become a free-living organism. While each of these individual craniofacial components is essential, the cranial and facial midline lies at a structural nexus that unites these disparately derived elements, fusing them into a whole...

Preterm births account for approximately 10% of births worldwide, with the majority (∼80%) being moderate preterm. Our aim was to determine the effects of moderate preterm birth on survival and long-term growth of male and female offspring using an ovine model of preterm birth that was preceded by a clinically relevant dose of corticosteroids. Ewes were induced to deliver preterm or at term; those assigned to deliver preterm were administered antenatal betamethasone (11.4 mg, 2 doses, 24 hours apart). The growth (body weight and body dimensions) of offspring was monitored to adulthood (62 weeks) when the animals were humanely killed for organ collection...

Organ formation in animals and plants relies on precise control of cell state transitions to turn stem cell daughters into fully differentiated cells. In plants, cells cannot rearrange due to shared cell walls. Thus, differentiation progression and the accompanying cell expansion must be tightly coordinated across tissues. PLETHORA (PLT) transcription factor gradients are unique in their ability to guide the progression of cell differentiation at different positions in the growing Arabidopsis root, which contrasts with well-described transcription factor gradients in animals specifying distinct cell fates within an essentially static context...

: Haloarchaea are extremely halophilic heterotrophic microorganisms belonging to the class Halobacteria (Euryarchaeota). Almost half of the haloarchaea possesses the genes coding for enzymes of the methylaspartate cycle, a recently discovered anaplerotic acetate assimilation pathway. In this cycle, the enzymes of the tricarboxylic acid cycle together with the dedicated enzymes of the methylaspartate cycle convert two acetyl-CoA molecules to malate. The methylaspartate cycle involves two reactions catalyzed by homologous enzymes belonging to the CitE-like enzyme superfamily, the malyl-CoA lyase/thioesterase (haloarchaeal malate synthase, hMS, Hah_2476 in Haloarcula hispanica) and the β-methylmalyl-CoA lyase (hMCL, Hah_1341)...

Ready or not, the Internet of things (IoT) is here. No longer just a buzz term, it'll continue to grow at an unprecedented pace over the next few years expecting to reach over 25 billion connected devices by 2020. History shows us that most fast growth technology solutions focus on solving business problems first and security is an afterthought. Unfortunately, IoT is following the same trend. Most IoT devices, apps, and infrastructure were developed without security in mind and are likely going to become targets of hackers...

Leaves are present in all land plants and are specialized organs for light harvesting. They arise at the flanks of the shoot apical meristem (SAM), and develop into lamina structures that exhibit adaxial/abaxial (upper/lower side of the leaf) polarity. At the molecular level, an intricate regulatory network determines ad-/abaxial polarity in Arabidopsis thaliana leaves, where the Class III Homeodomain Leucine Zipper (HD-ZIPIII) and KANADI (KAN) proteins are key mediators. The HD-ZIPIII REVOLUTA (REV) is expressed in the adaxial domain of lateral organs, whereas KAN1 is involved in abaxial differentiation...

The fabrication of oriented, crystalline films of metal-organic frameworks (MOFs) is a critical step toward their application to advanced technologies such as optics, microelectronics, microfluidics and sensing. However, the direct synthesis of MOF films with controlled crystalline orientation remains a significant challenge. Here we report a one-step approach, carried out under mild conditions, that exploits heteroepitaxial growth for the rapid fabrication of oriented polycrystalline MOF films on the centimetre scale...

The incorporation of metal-organic frameworks (MOFs) into membrane-shaped architectures is of great importance for practical applications. The currently synthesized MOF-based membranes show many disadvantages, such as poor compatibility, low dispersity, and instability, which severely limit their utility. Herein, we present a general, facile, and robust approach for the synthesis of MOF-based composite membranes through the in situ growth of MOF plates in the channels of anodized aluminum oxide (AAO) membranes...

An increase in both human population and economic growth has been accompanied by rising per capita demand for animal products. The livestock industry is under pressure to meet this demand, but its current patterns of production are not environmentally sustainable, causing negative health impacts on humans and raising welfare concerns for animals. With little regulation of the intensive livestock sector in most countries, animal products are available at cheaper prices on consumer markets, undercutting more sustainable production systems, such as those used by pastoralists and organic farmers...

Wildlife subsistence hunting is a major source of protein for tropical rural populations and a prominent conservation issue. The intrinsic rate of natural increase (rmax ) of populations is a key reproductive parameter in the most-used assessments of hunting sustainability. However, since researchers face severe difficulties in obtaining reproductive data in the wild, these assessments often use 'classic' reproductive rates calculated mostly from captive studies conducted 30 years ago, resulting in flaws in almost 50% of studies and hampering decision-makings on wildlife management...

Intussusceptive angiogenesis (IA) is required for normal embryonic vascular development. The Tie family of receptors and their ligands, the angiopoietins, play an important role in the growth or regression of blood vessels which are important not only during development but also throughout an organism's life. The presence of IA was investigated in glomerular capillaries of the fetal porcine metanephros using Mercox II resin casts. The first signs of IA were observed in stage III glomeruli. Stage IV and V glomeruli showed numerous signs of aligned pillar formation and their successive merging to delineate the vascular entities...

BACKGROUND: Intervertebral disc degeneration (IVDD) is considered a multifactorial disease that is influenced by both environmental and genetic factors. The last two decades of research strongly demonstrate that genetic factors contribute about 75% of the IVDD etiology. Recent total genome sequencing studies have shed light on the various single-nucleotide polymorphisms (SNPs) that are associated with IVDD. AIM: This review presents comprehensive and updated information about the diversity of genetic factors in the inflammatory, degradative, homeostatic, and structural systems involved in the IVDD...

Target of Rapamycin (TOR) signaling is an important regulator in multiple organisms including yeast, plants, and animals. However, the TOR signaling in plants is much less understood as compared to that in yeast and animals. TOR kinase can be efficiently suppressed by rapamycin in the presence of functional FK506 Binding Protein 12 KD (FKBP12) in yeast and animals. In most examined higher plants rapamycin fails to inhibit TOR kinase due to the non-functional FKBP12. Here we find that tomato plants showed obvious growth inhibition when treated with rapamycin and the inhibitory phenotype is similar to suppression of TOR causing by active-site TOR inhibitors (asTORis) such as KU63794, AZD8055, and Torin1...

In plant-associated Pseudomonas species, the production of several secondary metabolites and exoenzymes is regulated by the GacS/GacA two-component regulatory system (the Gac-system). Here, we investigated if a mutation in the GacS sensor kinase affects the production of volatile organic compounds (VOCs) in P. fluorescens SBW25 (Pf.SBW25) and how this impacts on VOCs-mediated growth promotion and induced systemic resistance of Arabidopsis and tobacco. A total of 205 VOCs were detected by Gas Chromatography Mass Spectrometry for Pf...

Quorum sensing (QS) is cell-cell communication mechanism mediated by signaling molecules known as autoinducers (AIs) that lead to differential gene expression. Salmonella is unable to synthesize the AI-1 acyl homoserine lactone (AHL), but is able to recognize AHLs produced by other microorganisms through SdiA protein. Our study aimed to evaluate the influence of AI-1 on the abundance of proteins and the levels of organic acids of Salmonella Enteritidis. The presence of N-dodecyl-homoserine lactone (C12-HSL) did not interfere on the growth or the total amount of extracted proteins of Salmonella...
