In the United States (U.S.), pet turtles have been associated with outbreaks of salmonellosis, a serious and sometimes-fatal intestinal illness caused by Salmonella bacteria, with nearly 300,000 people being infected in some years. Children are particularly susceptible because of their propensity to put items, including small turtles, in their mouths. In 1975, a U.S. federal regulation prohibited the sale of turtles <4 inches (101.6 mm) in size, except for the purposes of export, scientific, or educational purposes. This regulation was established to reduce the incidence of salmonellosis, particularly in small children. Previous research has not evaluated the availability of turtles <4 inches in size on websites selling wildlife. We monitored 16 websites in 2021 and quantified listings of small turtles. We determined whether information on Salmonella , the 1975 federal regulation, or related state regulations were provided on the websites and determined legality of sales of small turtles by state regulations. We found that all 16 websites openly advertised and sold turtles <4 inches in size, but only half of these websites provided information about Salmonella and/or the federal regulation. These websites required buyers to confirm that they were not purchasing a turtle as a pet, thereby putting the onus on the consumer to adhere to the regulation. We documented 515 listings of turtles <4 inches in size, including 47 species and one hybrid. Our study has demonstrated that internet sales of small turtles currently represent part of the thriving online pet trade in the U.S. Enforcement of the federal regulation faces jurisdictional challenges in most states. Therefore, we recommend continued public education campaigns by public health agencies in the U.S. to help reduce the risk that pet turtle ownership presents.

The effects of 1 year of zidovudine, lamivudine, and ritonavir treatment on immune re-constitution were evaluated in 34 human immunodeficiency virus (HIV)-infected individuals. After 48 weeks of therapy, 20 (59%) subjects had <100 copies HIV RNA/mL. CD4+ T cells increased from a median of 192/mm3 at baseline to 362/mm3 at week 48. Lymphocyte prolif-erative responses to Candida normalized within 12 weeks, but responses to HIV and tetanus remained depressed throughout therapy. Alloantigen responses increased within 12 weeks and then declined to baseline levels. Recovery of delayed-type hypersensitivity responses occurred after 12 weeks for Candida and after 48 weeks for mumps. The magnitude of virologic suppression was correlated with numeric increases in CD4+ T cells, but not with measures of functional immune reconstitution. Plasma virus suppression <100 copies/mL was not significantly correlated with increases in CD4+ T cells or functional immune reconstitution.

Use of human immunodeficiency virus (HIV) drug-resistance testing in therapeutic decision making may be aided by understanding the relationship between results of genotypic and drug-susceptibility phenotypic assays. We investigated this relationship by applying 3 different statistical methods—cluster analysis, recursive partitioning, and linear discriminant analysis—to results for 72 patients followed in the Adult AIDS Clinical Trials Group (ACTG) protocol 333. ACTG 333 was a multicenter, randomized trial comparing 2 formulations of saquinavir (SQV) to indinavir (IDV) in patients with extensive hard-gel SQV experience. Data include protease amino acid sequences and 50% inhibitory concentrations for SQV and IDV at baseline. The 3 methods give similar results showing the association of mutations at codons 10, 63, 71, and 90 with in vitro resistance to IDV and SQV. Recursive partitioning is especially useful because it can identify interactions among mutations at different codons and accommodates many types of data as well as missing observations.

Tight relationships exist in the local Universe between the central stellar properties of galaxies and the mass of their supermassive black hole (SMBH) 1 – 3 . These suggest that galaxies and black holes co-evolve, with the main regulation mechanism being energetic feedback from accretion onto the black hole during its quasar phase 4 – 6 . A crucial question is how the relationship between black holes and galaxies evolves with time; a key epoch to examine this relationship is at the peaks of star formation and black hole growth 8–12 billion years ago (redshifts 1–3) 7 . Here we report a dynamical measurement of the mass of the black hole in a luminous quasar at a redshift of 2, with a look back in time of 11 billion years, by spatially resolving the broad-line region (BLR). We detect a 40-μas (0.31-pc) spatial offset between the red and blue photocentres of the Hα line that traces the velocity gradient of a rotating BLR. The flux and differential phase spectra are well reproduced by a thick, moderately inclined disk of gas clouds within the sphere of influence of a central black hole with a mass of 3.2 × 10 8  solar masses. Molecular gas data reveal a dynamical mass for the host galaxy of 6 × 10 11  solar masses, which indicates an undermassive black hole accreting at a super-Eddington rate. This suggests a host galaxy that grew faster than the SMBH, indicating a delay between galaxy and black hole formation for some systems. Using the GRAVITY+ instrument, dynamical measurement of the black hole mass in a quasar at a redshift of 2.3 (11 billion years ago) shows how the relationship between galaxies and black holes evolves with time.

Background. Although the determinants of immune deficiency and immune restoration in chronic human immunodeficiency virus (HIV)–1 infection are not well understood, immune activation has been proposed as being central to the pathogenesis of HIV. Methods. A randomized, controlled trial of cyclosporin A treatment for 2 weeks was performed in persons with chronic HIV‐1 infection who were beginning a standardized antiretroviral therapy (ART) regimen. Results. Treatment with cyclosporin A provided only a marginal and transient enhancement in circulating T cell restoration that was largely restricted to cells expressing the CCR7 chemokine receptor and that did not persist beyond 2 weeks. Conclusions. Cyclosporin A coadministered for 2 weeks with ART provided no sustained immunologic benefit to persons with chronic HIV‐1 infection. If immune activation drives progressive immune deficiency in chronic HIV‐1 infection, these activation pathways may not be sensitive to cyclosporin.

The majority of dental carie studies over the course of historical period underline mainly the prevalence evolution, the role of carbohydrates consumption and the impact of access to dietary resources. The purpose of the present investigation was to compare population samples from two archaeological periods the Chacolithic and Middle Age taking into account the geographical and socio economical situation. The study concerned four archaelogical sites in south west France and population samples an inlander for the Chalcolithic Age, an inlander, an costal and urban for the Middle Age. The materials studied included a total of 127 maxillaries, 103 mandibles and 3316 teeth. Data recorded allowed us to display that the Chalcolithic population sample had the lowest carie percentage and the rural inlander population samples of Middle Age the highest; in all cases molars were teeth most often affected. These ones differences could be explained according to time period, carious lesions were usually less recorded in the Chalcolithic Age than the Middle because of a lesser cultivation of cereals like in les Treilles Chacolithic population sample. In the Middle Age population samples, the rural inland sample Marsan showed the highest frequency of caries and ate more cereal than the coastal Vilarnau and the poor urban St Michel population samples, the first one ate fish and Mediterranean vegetal and fruits and the second one met difficulties to food access, in both cases the consumption of carbohydrates was lesser than Marsan population sample who lived in a geographical land convice to cereals cultivation.

Repetitive and restricted behaviors and interests are a major feature of Autism Spectrum Disorder (ASD). Insistence on sameness, rigid adherence to rituals and routines and resistance to change, and related symptoms can have a highly disruptive impact on an individual’s ability to transition from one task to the next and progress through the different steps within a task. Difficulties with transitions can represent a major barrier in treatment and care, impede learning, and contribute to significant distress in individuals with an ASD. A number of behavioral approaches to facilitating transitions in persons with an ASD have been investigated. The current paper reviews the available research on strategies to support individuals in transitions between daily activities and tasks. Current trends and future directions are discussed.

RésuméCet article analyse, à partir d’un modèle intégratif et dynamique, la souffrance au travail et les manifestations de celle-ci, chez les agents pénitentiaires en milieu carcéral dans un espace particulier qui est celui du « parloir pénitentiaire ». Si les questions des facteurs de risques, notamment du stress ou du burn out ont été abondamment traitées dans la littérature, selon des approches factorielles, rares sont les modèles multidimensionnels existants qui permettent de comprendre la complexité et la spécificité des processus en jeu en milieu carcéral. La méthode de recherche relève d’une analyse comparative des espaces professionnels. Soixante-douze entretiens semi-directifs de recherche ont été conduits auprès des surveillants occupant chacun des espaces, dans trois établissements pénitentiaires français. À partir de différents indicateurs, le modèle permet de saisir les processus et étapes qui conduisent à la manifestation de souffrances au travail. Il offre à la fois des perspectives d’intervention et de prévention pour les cadres et psychologues chargés du soutien aux personnels. Suffering at work in prisonThis article uses an integrative and dynamic model to analyze suffering at work, and its manifestations, experienced by correctional officers in prisons in a particular space known as the « prison visiting room ». Such risk factors as stress and burnout have already been extensively considered in the literature, based on factorial approaches. However, it is rare to find existing multidimensional models that allow for an understanding of the complexity and specificity of processes in prison. The constructed model distinguishes between different levels of reading within six axes of detention warders in which professional positioning conflictualization (Moulin, Sevin, 2010) has been identified as likely to develop deadlock (Sami Ali, 2002) in the exercise of their profession. Professional positioning is viewed in terms of adaptive management, and operationalized on behavioral, axiological and psychic levels. Suffering at work results in the expression and acting out of various psychic and somatic symptoms. From various indicators, the model enables the processes to be identified, along with the steps that lead to the manifestation of suffering at work. It offers opportunities for intervention and prevention for managers and psychologists in charge of supporting the prison staff.The research method draws a comparative analysis through the investigation of professional spaces, including: visiting rooms, places of care, doors, watchtowers, and minor district and passageways. Seventy-two semi-directive research interviews were carried out with detention officers who occupy posts in each of these areas, in three French penitentiaries.The results show that, regardless of the workspace, the institutional framework (Fustier, 1999), seems potentially weakening for the agents because of two main dimensions: the architectural organization of places and the “paradoxical” missions devolved to the tasks of surveillance. The specificity of the visiting room lies in the introduction of families and close relations as objects of surveillance. This results in the conflictualization of the professional positions on the « spatial » axis because of the overlapping of the public, private and intimate places, the perceived transgressive intrusion into intimacy and the necessity of control in this case. These first elements, combined with the families’ perceptions and assessments, and the identification of phenomena, have repercussions on the axis named « legalities-legitimacies », which put at risk the legitimacy of the detention officer in the enforcement of the prison rules. The position of authority is then weakened, with he detention officer not feeling legitimate and authorized to intervene as a third party in relations between the prisoner and his family.If this workspace is confrontational and generates counter attitudes that are perceptible both in terms of the behavioral, axiological plane, and defensive psychological movements, the latter remain adaptive because they do not involve physical or psychic symptoms, nor are they acted out. Various indicators suggest the need for preventive intervention before the adaptive capacities of the detention officers are exceeded.

We have identified three polymorphic microsatellites (which we call TNFa, TNFb, and TNFc) within a 12-kilobase region of the human major histocompatibility complex (MHC) that includes the tumor necrosis factor (TNF) locus. TNFc is located within the first intron of the TNF-β gene and has only 2 alleles. TNFa and TNFb are 3.5 kilobases upstream (telomeric) of the TNF-β gene and have at least 13 and 7 alleles, respectively. TNFa, -b, and -c alleles are in linkage disequilibrium with alleles at other loci within the MHC, including class I, class II, and class III. TNFa, -b, and -c alleles are also associated with extended HLA haplotypes. These TNF polymorphisms will allow a thorough genetic analysis of the involvement of TNF in MHC-linked pathologies.
