Shifting Focus: Redefining the Goals of Sea Turtle Consumption and Protection in Bali

Many would say that the environment and human culture consists of an evolutionary process, complete with necessary adaptations to current situations and the availability of resources. However, religion is usually thought to be a constant, an entity that grounds the individual believer in a “truth” that transcends time. Ultimately, the boundary between culture and religion is especially hard to decipher, particularly in the daily rituals of the Balinese. While religious beliefs are often rooted in history, they too transform through inevitable reinterpretation. The following paper describes the tremendous environmental and cultural impact of the controversial turtle trade in Bali, specifically in regards to the use of turtle in religious ritual. -- excerpt from introductio

Green, Yellow, and Red risk perception in everyday life - a communication tool

Background: Adolescents have the highest risk for food allergy-related fatalities. Our main aim was to investigate the level of risk in everyday social situations as perceived by adolescents/young adults with peanut allergy, their families, and their friends. Methods: The web-based ‘Colours Of Risks’ (COR) questionnaire was completed by 70 patients (aged 12–23 years), 103 mothers and fathers, 31 siblings (aged 12–26 years), and 42 friends (aged 12–24 years). COR deals with six main contexts (home, school/university, work, visiting/social activities, special occasions/parties, and vacations), each with 1-12 items. Response categories are green (I feel safe), yellow (I feel uncertain), or red (I feel everything is risky). Results: There was a high level of agreement between participants in defining situations as safe, uncertain, or risky, but female patients and mothers rated fewer situations as safe compared to male patients and fathers. Being with close friends and family, and attending planned parties without alcohol were perceived as situations of low risk. While 94% of patients took an epinephrine auto-injector (EAI) into risky situations, only 65% took it into safe situations. In contrast to the close family, 31% of the friends did not know the patient had an EAI, and fewer knew how to administer the EAI. Conclusion: Young adults with peanut allergy face challenges when moving from the safe home with ready assistance if needed, to independence with unpredictable surroundings and less certain help. Perceived ‘safe’ situations may in fact be the riskiest, as patients often do not take the EAI with them

Quality of life in childhood, adolescence and adult food allergy: patient and parent perspectives

Background: Studies of children with food allergy typically only include the mother and have not investigated the relationship between the amount of allergen needed to elicit a clinical reaction (threshold) and health-related quality of life (HRQL). Our aims were (i) to compare self-reported and parent-reported HRQL in different age groups, (ii) to evaluate the impact of severity of allergic reaction and threshold on HRQL, and (iii) to investigate factors associated with patient-reported and parent-reported HRQL. Methods: Age-appropriate Food Allergy Quality of Life Questionnaires (FAQLQ) were completed by 73 children, 49 adolescents and 29 adults with peanut, hazelnut or egg allergy. Parents (197 mothers, 120 fathers) assessed their child's HRQL using the FAQLQ-Parent form. Clinical data and threshold values were obtained from a hospital database. Significant factors for HRQL were investigated using univariate and multivariate regression. Results: Female patients reported greater impact of food allergy on HRQL than males did. Egg and hazelnut thresholds did not affect HRQL, but lower peanut threshold was associated with worse HRQL. Both parents scored their child's HRQL better than the child's own assessment, but whereas mother-reported HRQL was significantly affected by limitations in the child's social life, father-reported HRQL was affected by limitations in the family's social life. Severity of allergic reaction did not contribute significantly to HRQL. Conclusion: The risk of accidental allergen ingestion and limitations in social life are associated with worse HRQL. Fathers provide a unique perspective and should have a greater opportunity to contribute to food allergy research

Priapism After Epidural or Spinal Anesthesia

Introduction: Preoperative epidural and spinal anesthesia improves patient outcomes by reducing potential side effects due to prolonged treatment with general anesthesia as well as mitigating postoperative pain. Rarely, patients receiving epidural and spinal anesthesia develop priapism secondary to administration of the anesthetic agent. Little is known about the development of this complication and its management following onset. Rationale: A case of priapism following administration of epidural anesthesia in Kalamazoo, MI, at Bronson Methodist Hospital, prompted a search of the literature into the etiology, pathophysiology, and management of such cases. Review of Literature: A search of two databases was conducted, including keywords “priapism, anesthesia, epidural, humans” among others. This search produced 305 unique articles. Priapism cases due to underlying conditions, such as sickle cell anemia, were excluded. All cases of non-spinal and non-epidural anesthesia were excluded. In total, 36 articles from the search were included in this review. Subsequently, a hand review of the selected articles produced an additional 121 new papers which are currently under review and may be included in our final review. Results: Priapism appears to be a rare complication of anesthesia, but cases are often unreported and real incidence is unknown. Overall incidence of priapism in the United States is 0.2-0.3 cases/100,000. Etiology and contribution of medical, genetic, and environmental factors are unclear. Bolus doses of bupivicaine were involved in multiple reported cases. Interestingly, epidural anesthesia can both cause and treat priapism, suggesting that pathophysiology involves an imbalance of the parasympathetic and sympathetic tone of the penile vasculature. Timing of erection onset complicates treatment of this side effect. Preoperatively, the inciting agent is generally withdrawn and the procedure is postponed until other anesthetic options are explored. Postoperatively, another anesthetic is administered for pain relief. Intraoperatively, the appropriate course of action is multifactorial, depending patient’s underlying health status and variables inherent to the procedure. No long-term adverse effects, such as erectile dysfunction or dysuria, were reported. During the episode patients experienced distress at the inability to urinate and acute pain from the prolonged erection. Conclusion: Priapism due to epidural and spinal anesthesia remains a mysterious phenomenon. Bupivicaine has been suggested as a causative agent, perhaps selectively inhibiting sympathetic tone to the penile vasculature. There are many factors to consider when treating this complication, including procedural and patient characteristics

Structural conservation of chemotaxis machinery across Archaea and Bacteria

Chemotaxis allows cells to sense and respond to their environment. In Bacteria, stimuli are detected by arrays of chemoreceptors that relay the signal to a two-component regulatory system. These arrays take the form of highly stereotyped super-lattices comprising hexagonally packed trimers-of-receptor-dimers networked by rings of histidine kinase and coupling proteins. This structure is conserved across chemotactic Bacteria, and between membrane-bound and cytoplasmic arrays, and gives rise to the highly cooperative, dynamic nature of the signalling system. The chemotaxis system, absent in eukaryotes, is also found in Archaea, where its structural details remain uncharacterized. Here we provide evidence that the chemotaxis machinery was not present in the last archaeal common ancestor, but rather was introduced in one of the waves of lateral gene transfer that occurred after the branching of Eukaryota but before the diversification of Euryarchaeota. Unlike in Bacteria, the chemotaxis system then evolved largely vertically in Archaea, with very few subsequent successful lateral gene transfer events. By electron cryotomography, we find that the structure of both membrane-bound and cytoplasmic chemoreceptor arrays is conserved between Bacteria and Archaea, suggesting the fundamental importance of this signalling architecture across diverse prokaryotic lifestyles

Farnesol restores wild-type colony morphology to 96% of \u3ci\u3eCandida albicans\u3c/i\u3e colony morphology variants recovered following treatment with mutagens

Candida albicans is a diploid fungus that undergoes a morphological transition between budding yeast, hyphal, and pseudohyphal forms. The morphological transition is strongly correlated with virulence and is regulated in part by quorum sensing. Candida albicans produces and secretes farnesol that regulates the yeast to mycelia morphological transition. Mutants that fail to synthesize or respond to farnesol could be locked in the filamentous mode. To test this hypothesis, a collection of C. albicans mutants were isolated that have altered colony morphologies indicative of the presence of hyphal cells under environmental conditions where C. albicans normally grows only as yeasts. All mutants were characterized for their ability to respond to farnesol. Of these, 95.9% fully or partially reverted to wildtype morphology on yeast malt (YM) agar plates supplemented with farnesol. All mutants that respond to farnesol regained their hyphal morphology when restreaked on YM plates without farnesol. The observation that farnesol remedial mutants are so common (95.9%) relative to mutants that fail to respond to farnesol (4.1%) suggests that farnesol activates and (or) induces a pathway that can override many of the morphogenesis defects in these mutants. Additionally, 9 mutants chosen at random were screened for farnesol production. Two mutants failed to produce detectable levels of farnesol. Candida albicans est un champignon diploïde qui subit une transition morphologique entre les levures en herbe, les hyphes et les formes pseudohyphales. La transition morphologique est fortement corrélée à la virulence et est régulée en partie par la détection du quorum. Candida albicans produit et sécrète du farnésol qui régule la transition morphologique levure-mycélium. Les mutants qui ne parviennent pas à synthétiser ou à répondre au farnésol pourraient être verrouillés en mode filamenteux. Pour tester cette hypothèse, une collection de mutants de C. albicans a été isolée qui ont modifié les morphologies des colonies, indiquant la présence de cellules hyphales dans des conditions environnementales où C. albicans ne pousse normalement que sous forme de levures. Tous les mutants ont été caractérisés pour leur capacité à répondre au farnésol. Parmi ceux-ci, 95,9% sont entièrement ou partiellement revenus à la morphologie de type sauvage sur des plaques de gélose au levure de malt (YM) complétées par du farnésol. Tous les mutants qui répondent au farnésol ont retrouvé leur morphologie hyphale lorsqu\u27ils ont été recréés sur des plaques YM sans farnésol. L\u27observation selon laquelle les mutants curatifs du farnésol sont si communs (95,9%) par rapport aux mutants qui ne répondent pas au farnésol (4,1%) suggère que le farnésol s\u27active et (ou) induit une voie qui peut supplanter bon nombre des défauts de morphogenèse de ces mutants. De plus, 9 mutants choisis au hasard ont été testés pour la production de farnésol. Deux mutants n\u27ont pas réussi à produire des niveaux détectables de farnésol

Refining the accuracy of validated target identification through coding variant fine-mapping in type 2 diabetes.

We aggregated coding variant data for 81,412 type 2 diabetes cases and 370,832 controls of diverse ancestry, identifying 40 coding variant association signals (P < 2.2 × 10-7); of these, 16 map outside known risk-associated loci. We make two important observations. First, only five of these signals are driven by low-frequency variants: even for these, effect sizes are modest (odds ratio ≤1.29). Second, when we used large-scale genome-wide association data to fine-map the associated variants in their regional context, accounting for the global enrichment of complex trait associations in coding sequence, compelling evidence for coding variant causality was obtained for only 16 signals. At 13 others, the associated coding variants clearly represent 'false leads' with potential to generate erroneous mechanistic inference. Coding variant associations offer a direct route to biological insight for complex diseases and identification of validated therapeutic targets; however, appropriate mechanistic inference requires careful specification of their causal contribution to disease predisposition

Fried food consumption, genetic risk, and body mass index: gene-diet interaction analysis in three US cohort studies

Objective: To examine the interactions between genetic predisposition and consumption of fried food in relation to body mass index (BMI) and obesity. Design: Prospective cohort study. Setting: Health professionals in the United States. Participants: 9623 women from the Nurses’ Health Study, 6379 men from the Health Professionals Follow-up Study, and a replication cohort of 21 421 women from the Women’s Genome Health Study. Main outcome measure Repeated measurement of BMI over follow-up. Results: There was an interaction between fried food consumption and a genetic risk score based on 32 BMI-associated variants on BMI in both the Nurses’ Health Study and Health Professionals Follow-up Study (P≤0.001 for interaction). Among participants in the highest third of the genetic risk score, the differences in BMI between individuals who consumed fried foods four or more times a week and those who consumed fried foods less than once a week amounted to 1.0 (SE 0.2) in women and 0.7 (SE 0.2) in men, whereas the corresponding differences were 0.5 (SE 0.2) and 0.4 (SE 0.2) in the lowest third of the genetic risk score. The gene-diet interaction was replicated in the Women’s Genome Health Study (P<0.001 for interaction). Viewed differently, the genetic association with adiposity was strengthened with higher consumption of fried foods. In the combined three cohorts, the differences in BMI per 10 risk alleles were 1.1 (SE 0.2), 1.6 (SE 0.3), and 2.2 (SE 0.6) for fried food consumption less than once, one to three times, and four or more times a week (P<0.001 for interaction); and the odds ratios (95% confidence intervals) for obesity per 10 risk alleles were 1.61 (1.40 to 1.87), 2.12 (1.73 to 2.59), and 2.72 (2.12 to 3.48) across the three categories of consumption (P=0.002 for interaction). In addition, the variants in or near genes highly expressed or known to act in the central nervous system showed significant interactions with fried food consumption, with the FTO (fat mass and obesity associated) variant showing the strongest result (P<0.001 for interaction). Conclusion: Our findings suggest that consumption of fried food could interact with genetic background in relation to obesity, highlighting the particular importance of reducing fried food consumption in individuals genetically predisposed to obesity
