REVIEW
Asael Lubotzky, Adi Aran
Any medical treatment, whether it be medication, behavioral therapy or medical procedure, can affect the patient in a very complex way. Each of these forms of medical treatment have both psychobiological and physiological effects on the patient, with interactions between those levels. When considering the specific efficacy of a new treatment, there is therefore a need to neutralize the psychobiological effect by comparing the effect of the treatment to the effect of a placebo - a treatment involving similar characteristics which does not produce that physiological effect...

INTRODUCTION: Laparoscopic surgery has long been used for colon and rectal resection, and the laparoscopic-assisted approach has prevailed in surgical practice. While this technique includes the fashioning of an intra-corporeal anastomosis, it still requires an abdominal incision for specimen extraction. Elimination of the abdominal incision and its potential complications has been the motivation for the development of natural orifice specimen extraction (NOSE) techniques. Many of these techniques make use of an open rectal stump, which poses as a potential for intra-abdominal contamination...

BACKGROUND: The relationships between physicians and patients are very complex. One of their principles is to receive informed consent from the patient. This principle facilitates patient autonomy. The physician must explain to the patient: his condition, treatment alternatives, stating the advantages and disadvantages of each option, to enable the patient to choose between them. There are various attitudes towards the health system as a result of different cultures in different societies...

Given the shortage of medical providers and the need for medical decisions to be responsive to community needs, including lay health providers in health teams has been recommended as essential for the successful management of global health care systems. Brazil's Unified Health System (UHS) is a model for delivering community-based care through Family Health Strategy (FHS) interdisciplinary teams comprised of medical and lay health providers-Community Health Agents (CHAs), nurses, and physicians. This study aims to understand how medical and lay health providers' perceptions and attitudes could impact the delivery of community-based care...

Nucleoside diphosphate kinases (NDKs) are ubiquitous enzymes that catalyze the transfer of the γ-phosphate moiety from an NTP donor to an NDP acceptor, crucial for maintaining the cellular level of nucleoside triphosphates (NTPs). The inability of trypanosomatids to synthesize purines de novo and their dependence on the salvage pathway makes NDK an attractive target to develop drugs for the diseases they cause. Here we report the discovery of novel inhibitors for Leishmania NDK based on the structural and functional characterization of purified recombinant NDK from Leishmania amazonensis...

This article takes up the neuroscientific assumption of our brains as "solitary" and contrasts this understanding with the description of actual clinical practices. Drawing on observations of clinical consultations and team meetings in a world famous US center for the diagnosis of dementia, I examine how the "informant", a member of the patient's family, participates in the diagnosis process. Based on specific situations in which the informant is judged to be a "bad" one, I inquire as to how clinicians use what they understand of the affective relationships between the patient and the bad informant in order to make a diagnosis...

Autism spectrum disorder (ASD) is a complex neurodevelopmental condition with a strong genetic component. To date, several hundred different genetic mutations have been identified to play a role in its aetiology. The heterogeneity of genetic abnormalities combined with the different brain regions where aberrations are found makes the search for causative mechanisms a daunting task. Even within a limited number of brain regions, a myriad of different neural circuit dysfunctions may lead to ASD. Here, we review mouse models that incorporate mutations of ASD risk genes causing pathologies in the cerebellum and striatum and highlight the vulnerability of related circuit dysfunctions within these brain regions in ASD pathophysiology...

The stiff competition for water between agriculture and non-agricultural production sectors makes it necessary to have effective management of irrigation networks in farms. However, the process of selecting flow control structures in irrigation networks is highly complex and involves different levels of decision makers. In this paper, we apply multi-attribute decision making (MADM) methodology to develop a decision analysis (DA) framework for evaluating, ranking and selecting check and intake structures for irrigation canals...

REVIEW

Cells deriving from neural crest are generally acknowledged during embryonic development for their multipotency and plasticity, accounting for their capacity to generate various cell and tissue types even across germ layers. At least partial preservation of some of these properties in adulthood makes neural crest derived cells of large interest for regenerative purposes. Chondrocytes from fully mature nasal septum cartilage in adults are also derivatives of neural crest cells and were recently demonstrated to be able not only to maintain functionality across serial cloning, as surrogate self-renewal test, but also to respond and adapt to heterotopic transplantation sites...

Under the background of increasing and sustainable development of nuclear industry, it is significant to develop materials with high adsorption capacity and high selectivity of uranium as adsorbents. In this work, novel Mg-Co layered-double-hydroxide (LDH) with hierarchical structure was synthesized successfully via self-sacrifice template by ZIF-67. X-ray diffraction (XRD) technique, scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FT-IR), Brunauer-Emmett-Teller surface area measurement (BET) and X-ray photoelectron spectroscopy (XPS) characterization were conducted, which confirmed the specifically hollow structured material possesses high surface area and abundant mesopores that makes uranium ions diffuse into it more easily...

Increasingly, in vitro assays evaluate a compound's tendency to maintain supersaturation towards improving oral absorption. Throughput remains a challenge and only small sets of compounds are evaluated in reported studies. The present work describes an automated workflow and data analysis approach to determine supersaturation stability after 16 minutes. Eight increasing concentrations were targeted and supernatant concentration was measured following solvent-shift in FaSSIF. The effect of DMSO on both equilibrium solubility and on induced supersaturation was addressed, while the change in concentration was evaluated over time...
