Thermal tolerances are affected by the range of temperatures that species encounter in their habitat. Daniel Janzen hypothesized in his "Why mountain passes are higher in the tropics" that temperature gradients were effective barriers to animal movements where climatic uniformity was high. Sea turtles bury their eggs providing some thermal stability that varies with depth. We assessed the relationship between thermal uniformity and thermal tolerance in nests of three species of sea turtles. We considered that barriers were "high" when small thermal changes had comparatively large effects and "low" when the effects were small...

Saul M Kassin
Well known in popular culture, the 1964 murder of Kitty Genovese in Queens, New York, became famous because not one of an alleged 38 bystanders called police until it was too late. Within psychology, this singular event inspired the study of bystander intervention. With the spotlight of history focused on Ms. Genovese and bystanders, other events, also profound for what they tell us about human social behavior, have escaped public notice. Based on archival records and current interviews, this article describes the three issues linked to Genovese...

This article focuses on the interplay between narcissistic leaders and organizations. It attempts to capture the gist of this interplay with a model outlining the narcissistic organizational trajectory. The Energy Clash Model borrows and adapts a phase/state physics metaphor to conceptualize narcissism as a force that enters or emerges in a stable system (i.e., organization) as a leader, destabilizes it, and stabilizes it at a different state or is expelled. The model consists of three time-contingent phases: perturbation, conflict, and resolution...

Lymphedema distichiasis syndrome (LDS) is a rare, autosomal dominant genetic condition, characterized by lower limb lymphedema and distichiasis. Other associated features that have been reported include varicose veins, cleft palate, congenital heart defects, and ptosis. We update a previously reported family with a pathogenic variant in FOXC2 (c.412-413insT) where five affected individuals from the youngest generation had congenital renal anomalies detected on prenatal ultrasound scan. These included four fetuses with hydronephrosis and one with bilateral renal agenesis...

MED12 is a multiprotein mediator complex, which has a role in cell growth and differentiation and has been implicated in three distinct X-linked intellectual disability syndromes with distinctive clinical features. These include Opitz-Kaveggia syndrome (FG syndrome), Lujan syndrome, and X-linked Ohdo syndrome. Recently MED12 variants have been implicated in isolated X-linked intellectual disability. We describe a 5-year-old male patient with intellectual disability and facial dysmorphism and a novel variant in MED12 gene identified by Whole Exome Sequencing...

Thermus thermophilus is an extremely thermophilic eubacterium that produces various polyamines. Aminopropylagmatine ureohydrolase (SpeB) and SAM decarboxylase-like protein 1 (SpeD1) are involved in the biosynthesis of spermidine from arginine. Because long and branched polyamines in T. thermophilus are synthesized from spermidine, the speB and speD1 gene-deleted strains (ΔspeB and ΔspeD1, respectively) cannot synthesize long and branched polyamines. Although neither strain grew at high temperatures (>75°C) in minimal medium, both strains survived at 80°C when they were cultured at 70°C until the mid-log phase and then shifted to 80°C...

BACKGROUND: The recovery process of a psychiatric patient is related to his primary informal caregiver's style of coping with stress. There is insufficient literature on validations of instruments that measure coping styles in this population. OBJECTIVE: To adapt and validate a scale to measure coping strategies in primary informal caregivers. METHOD: The adapted scale was based on the Extreme Coping Scale of López-Vázquez and Marván. Items from that scale were adapted for application to informal caregivers...

AIM: The purpose of this qualitative study was to explore the administrative supervisors' perspective of their managerial practices and how these practices contribute to nurse and patient safety. BACKGROUND: The position of administrative supervisor, often referred to as house supervisor on the evening and night shifts, lacks empirical data supporting efficacy. METHOD: A focused ethnographic study was conducted with 30 administrative supervisors from acute care hospitals, using in-depth interviews and job descriptions...

AlleyCatE is a de novo designed esterase that can be allosterically regulated by calcium ions. This artificial enzyme has been shown to hydrolyze p-nitrophenyl acetate (pNPA) and 4-nitrophenyl-(2-phenyl)-propanoate (pNPP) with high catalytic efficiency. AlleyCatE was created by introducing a single histidine residue (His(144) ) into a hydrophobic pocket of calmodulin. In this work, we explore the determinants of catalytic properties of AlleyCatE. We obtained the pKa value of the catalytic histidine using experimental measurements by NMR and pH rate profile and compared these values to those predicted from electrostatics pKa calculations (from both empirical and continuum electrostatics calculations)...

Ubald was a Catholic Church Saint (1084 - 1160), born in Gubbio (Umbria, Italy) and died after two years of painful illness; his mummy is now guarded in a glass sarcophagus at Sant'Ubald Cathedral in Gubbio. Informations about Ubald are derived by his two main biographers: Iordanus (Giordano) of Città di Castello(1) and Theobaldus (Teobaldo), his successor in the episcopal seat(2) .

We report the placement of a permanent transvenous nonselective His bundle pacing lead in conjunction with a transvenous pacemaker/ICD in an adult with Levo-Transposition of the Great Arteries (L-TGA) and a stenotic coronary sinus (CS) ostium (os), which would not accommodate a transvenous LV pacing lead. Nonselective His bundle pacing provided a nearly identical ventricular activation pattern in this previously unpaced patient. Many L-TGA patients will have an eventual need for permanent pacing and, given the challenges of CS cannulation, His bundle pacing may represent a preferred modality rather than pure morphologic LV pacing or surgical systemic ventricular lead placement to achieve optimal electrical synchrony...

Shortly after the Presidential Commission for the Study of Bioethical Issues was constituted in 2010 and days before the commission members were to join a conference call to discuss possible topics for their deliberation, Craig Venter held a press conference announcing that his lab had created a synthetic chromosome for a species of mycoplasma and had inserted this genetic material into organisms of another species of mycoplasma (the genes of which had been deactivated), transforming the host species into the donor species...

I once heard John Arras, who was one of bioethics' bright lights and, toward the end of his life, a member of the Presidential Commission for the Study of Bioethical Issues, remark that it is hard for an ethics commission not to "do paint-by-numbers ethics." What I think Arras had in mind is an approach that, in the set of essays that make up this special report, Rebecca Dresser describes as a listing of "general, often relatively uncontroversial" moral positions to support largely procedural recommendations...

Phototherapy is a useful noninvasive therapy, but it can induce cutaneous malignant tumours, including squamous cell carcinoma (SCC) and basal cell carcinoma (BCC). We report on a 79-year-old man who had long-standing mycosis fungoides for 40 years, which had been treated with psoralen ultraviolet A therapy for 37 years at a dose of approximately 5000 J/cm(2) . Approximately 6 years before presentation, numerous types of cutaneous malignancies, including actinic keratosis, BCC and SCC, had begun to develop all over the patient's body...

BACKGROUND: Pure red cell aplasia (PRCA) is a well-documented potential side effect of ABO major mismatched allogeneic hematopoietic stem cell transplants. This side effect may be self-limiting, but is sometimes treated using modalities such as steroids, antithymocyte globulin, donor lymphocyte infusions, rituximab, or plasma exchanges. Another well-documented cause of pure red cell aplasia is a chronic parvovirus B19 infection, which may be seen in immunocompromised hosts. The treatment of this cause of PRCA includes removal of immunosuppression, intravenous immunoglobulin (IVIg), or rituximab; however, this condition may also be self-limiting...

This is a paper showing how a concept central to the work of Wilfred Bion, and one of Klein's important recommendations concerning the practice of analysis with adults and small children, can both be seen in the light of Freud's earliest formulation of the origin of anxiety and the mother's first responses to her infant in distress. In the paper I suggest that these clinically influential concepts of Klein and Bion show an underlying consistency and affinity with Freud's early ideas about the management of anxiety in the mother-infant relationship, described in two of his pre-psychoanalytic writings, How Anxiety Originates (1894b), and The Project for a Scientific Psychology (1950 [1895])...

We present the case of a 38-year-old man undergoing surgical repair of his pectoralis major tendon. An interscalene catheter was placed between the middle and lower trunks of the brachial plexus. Postoperatively, ropivacaine 0.2% was infused through postoperative day. The patient had excellent pain control requiring minimal opioid analgesics. A catheter between the middle and lower trunks of the brachial plexus provided excellent postoperative analgesia after pectoralis major tendon reinsertion. Additionally, the block likely protected the surgical repair during emergence from anesthesia and in the early postoperative period by providing a motor block of the pectoralis major muscle...

OBJECTIVE: The cochlear implant (CI) has been shown to be associated with better hearing, cognitive abilities, and functional independence. There is variability however in how much benefit each recipient derives from his or her CI. This study's primary objective is to determine the effects of individual and environmental characteristics on CI outcomes. DESIGN: Seventy-six adults who developed postlingual severe to profound hearing loss and received their first unilateral CI at 65 years and older were eligible for the study...
