Primate Kinship: Contributions from Cayo Santiago

Research on Cayo Santiago and Japan deserves credit for launching the study of primate kinship and for continuing to help shape it in important ways. This review describes the origins of kinship research on Cayo Santiago, beginning with Donald Sade's pioneering work establishing the concepts of kin preferences, matrilineal dominance systems and incest avoidance. It then reviews subsequent research by later Cayo Santiago researchers and alumni, focusing primarily on maternal kinship. Together these researchers have greatly expanded our knowledge of kin preferences in rhesus in terms of (i) what age‐sex classes, behaviors and types of kin show them, (ii) the ways in which kinship interfaces with rank, sex, age, and dispersal patterns, and (iii) the graded and variably limited nature of kin preferences in terms of degree of relatedness. Second, the argument for kin selection at least for some types of behavior has survived challenges posed by several alternative explanations, and has been both strengthened by recent findings of paternal kin preferences and narrowed by studies showing that unilateral altruism may extend only to very close kin. Third, work on Cayo Santiago has contributed to an appreciation that both current conditions and inherent social characteristics may influence the strength of kin preferences, and fourth, it has contributed to an understanding of the possible origins of our own species’ family systems. Cayo Santiago became a leader in kinship research in large part because of management practices that produce known extended lineages. These lineages have promoted and accelerated research on kinship, prompting other researchers to investigate its importance in other groups and species, where its effects only then became clear. The extended lineages remain valuable tools for research on a species that lives in a broad range of environments in the wild, including those with key parallels to Cayo Santiago. Am. J.

Molecular Characterization of Endocarditis-Associated Staphylococcus aureus

ABSTRACT Infective endocarditis (IE) is a life-threatening infection of the heart endothelium and valves. Staphylococcus aureus is a predominant cause of severe IE and is frequently associated with infections in health care settings and device-related infections. Multilocus sequence typing (MLST), spa typing, and virulence gene microarrays are frequently used to classify S. aureus clinical isolates. This study examined the utility of these typing tools to investigate S. aureus epidemiology associated with IE. Ninety-seven S. aureus isolates were collected from patients diagnosed with (i) IE, (ii) bloodstream infection related to medical devices, (iii) bloodstream infection not related to medical devices, and (iv) skin or soft-tissue infections. The MLST clonal complex (CC) for each isolate was determined and compared to the CCs of members of the S. aureus population by eBURST analysis. The spa type of all isolates was also determined. A null model was used to determine correlations of IE with CC and spa type. DNA microarray analysis was performed, and a permutational analysis of multivariate variance (PERMANOVA) and principal coordinates analysis were conducted to identify genotypic differences between IE and non-IE strains. CC12, CC20, and spa type t160 were significantly associated with IE S. aureus. A subset of virulence-associated genes and alleles, including genes encoding staphylococcal superantigen-like proteins, fibrinogen-binding protein, and a leukocidin subunit, also significantly correlated with IE isolates. MLST, spa typing, and microarray analysis are promising tools for monitoring S. aureus epidemiology associated with IE. Further research to determine a role for the S. aureus IE-associated virulence genes identified in this study is warranted.
Theory of Heating of a Nonreciprocal System of Particles

A simple theory, which describes a source of additional kinetic energy and its redistribution in systems of many particles with a nonreciprocal interaction (when Newton's third law is not valid), is presented. The theory yields the satisfactory results for a qualitative analysis of the features of dust dynamics in an anisotropic complex plasma. Unlike the theoretical models proposed earlier to explain the anomalous heating in the systems of particles with a nonreciprocal interaction, the model presented here allows to predict not only the kinetic energy growth for grains in laboratory RF discharges, but also an increase of their kinetic temperature in the direction of an ion flow as well as a difference in the energy distribution between the degrees of freedom. To verify the theory, we carried out numerical simulations of vertically aligned chains and extended-layered structures with a nonreciprocal model of interaction that is similar to interaction due to an effect of the ion focusing in a laboratory complex plasma.
Attitudes About Sexual Activity Among Postmenopausal Women in Different Ethnic Groups: A Cross-sectional Study in Jahrom, Iran

Background: Sexual function is affected by personal and interpersonal factors, familial and social traditions, culture, religion, menopause, and aging. So, ethnicity is a determining factor in sexual function. The present study aimed to investigate the prevalence of sexual dysfunction and attitudes towards sexuality in postmenopausal women among three different ethnic groups in Iran. Methods: This cross-sectional study was conducted on 746 postmenopausal women between 50 and 89 years who referred to Honoree clinic, Jahrom in 2013. Among the study participants, 42.4% were Arab, 33.5% were Persian, and 24.1% were Lor. Data were collected about women's socio-demographic characteristics, attitudes regarding sexuality and sexual function. The descriptive statistics were used for demographic variables. Moreover, ANOVA, post hoc (LSD) was used. Besides, p<0.05 was considered statistically significant. Results: The participants' mean age was 60.10±6.89 years and the total mean score of Female Sexual Function Index (FSFI) was 19.31±8.5. In addition, 81.5% of the women had sexual dysfunction (FSFI <26.55) and only 147 women (18.5%) had normal sexual function (FSFI >26.55). Sexual dysfunction was 75.3% in Arabs, 83.2% in Persians, and 86.1% in Lors. Besides, the most prevalent sexual dysfunction was dyspareunia in Arabs and arousal disorder in Persians and Lors. Conclusion: The results of this study showed that sexual dysfunction is considerable among postmenopausal women. The most prevalent sexual dysfunction was dyspareunia in Arabs and arousal disorder in Persians and Lors.
Energy Drink Use and Its Relationship to Masculinity, Jock Identity, and Fraternity Membership Among Men

The present study examined whether previous findings linking masculinity constructs and health behaviors applied to a relatively recent health risk behavior for men, the consumption of energy drinks. In addition, it also examined whether self-identifying as a jock and being a member of a fraternity would moderate the relationships between masculinity constructs and energy drink consumption. A total of 589 men completed measures of three masculinity constructs (endorsement of traditional masculinity ideology, conformity to masculine norms, and gender role conflict), energy drink consumption, jock identity, and fraternity membership, in addition to a demographic questionnaire. Age, endorsement of traditional masculinity ideology, and conforming to the masculine norms of risk taking and primacy of work were identified to be significant predictors of energy drink consumption. Furthermore, jock identity moderated the relationship between the endorsement of traditional masculinity ideology and energy drink consumption whereas fraternity membership moderated the relationship between conforming to the masculine norm of violence and energy drink consumption. Limitations, implications, and potential future directions are discussed.
Indirect regulation of the intestinal H+‐coupled amino acid transporter hPAT1 (SLC36A1)

A H+‐coupled amino acid transporter has been characterised functionally at the brush border membrane of the human intestinal cell line Caco‐2. This carrier, hPAT1 (human Proton‐coupled Amino acid Transporter 1) or SLC36A1, has been identified recently at the molecular level and hPAT1 protein is localised to the brush border membrane of human small intestine. hPAT1 transports both amino acids (e.g., β‐alanine) and therapeutic agents (e.g., D‐cycloserine). In human Caco‐2 cells, hPAT1 function (H+/amino acid symport) is associated with a decrease in intracellular pH (pHi), which selectively activates the Na+/H+ exchanger NHE3, and thus maintains pHi and the driving force for hPAT1 function (the H+ electrochemical gradient). This study provides the first evidence for regulation of hPAT1 function. Activation of the cAMP/protein kinase A pathway in Caco‐2 cell monolayers either using pharmacological tools (forskolin, 8‐br‐cAMP, [11,22,28Ala]VIP) or physiological activators (the neuropeptides VIP and PACAP) inhibited hPAT1 function (β‐alanine uptake) at the apical membrane. Under conditions where NHE3 is inactive (the absence of Na+, apical pH 5.5, the presence of the NHE3 inhibitor S1611) no regulation of β‐alanine uptake is observed. Forskolin and VIP inhibit pHi recovery (NHE3 function) from β‐alanine‐induced intracellular acidification. Immunocytochemistry localises NHERF1 (NHE3 regulatory factor 1) to the apical portion of Caco‐2 cells where it will interact with NHE3 and allow PKA‐mediated phosphorylation of NHE3. In conclusion, we have shown that amino acid uptake via hPAT1 is inhibited by activators of the cAMP pathway indirectly through inhibition of NHE3 activity. © 2005 Wiley‐Liss, Inc.
Regulation of Synaptic Amyloid-β Generation through BACE1 Retrograde Transport in a Mouse Model of Alzheimer's Disease

Amyloid-β (Aβ) peptides play a key role in synaptic damage and memory deficits in the early pathogenesis of Alzheimer's disease (AD). Abnormal accumulation of Aβ at nerve terminals leads to synaptic pathology and ultimately to neurodegeneration. β-site amyloid precursor protein (APP) cleaving enzyme 1 (BACE1) is the major neuronal β-secretase for Aβ generation. However, the mechanisms regulating BACE1 distribution in axons and β cleavage of APP at synapses remain largely unknown. Here, we reveal that dynein–Snapin-mediated retrograde transport regulates BACE1 trafficking in axons and APP processing at presynaptic terminals. BACE1 is predominantly accumulated within late endosomes at the synapses of AD-related mutant human APP (hAPP) transgenic (Tg) mice and patient brains. Defective retrograde transport by genetic ablation of snapin in mice recapitulates late endocytic retention of BACE1 and increased APP processing at presynaptic sites. Conversely, overexpressing Snapin facilitates BACE1 trafficking and reduces synaptic BACE1 accumulation by enhancing the removal of BACE1 from distal AD axons and presynaptic terminals. Moreover, elevated Snapin expression via stereotactic hippocampal injections of adeno-associated virus particles in mutant hAPP Tg mouse brains decreases synaptic Aβ levels and ameliorates synapse loss, thus rescuing cognitive impairments associated with hAPP mice. Altogether, our study provides new mechanistic insights into the complex regulation of BACE1 trafficking and presynaptic localization through Snapin-mediated dynein-driven retrograde axonal transport, thereby suggesting a potential approach of modulating Aβ levels and attenuating synaptic deficits in AD. SIGNIFICANCE STATEMENT β-Site amyloid precursor protein (APP) cleaving enzyme 1 (BACE1) trafficking and synaptic localization significantly influence its β secretase activity and amyloid-β (Aβ) production. In AD brains, BACE1 is accumulated within dystrophic neurites, which is thought to augment Aβ-induced synaptotoxicity by Aβ overproduction. However, it remains largely unknown whether axonal transport regulates synaptic APP processing. Here, we demonstrate that Snapin-mediated retrograde transport plays a critical role in removing BACE1 from presynaptic terminals toward the soma, thus reducing synaptic Aβ production. Adeno-associated virus–mediated Snapin overexpression in the hippocampus of mutant hAPP mice significantly decreases synaptic Aβ levels, attenuates synapse loss, and thus rescues cognitive deficits. Our study uncovers a new pathway that controls synaptic APP processing by enhancing axonal BACE1 trafficking, thereby advancing our fundamental knowledge critical for ameliorating Aβ-linked synaptic pathology.
Tumor-targeted TNFα stabilizes tumor vessels and enhances active immunotherapy

Solid tumors are intrinsically resistant to immune rejection. Abnormal tumor vasculature can act as a barrier for immune cell migration into tumors. We tested whether targeting IFNγ and/or TNFα into pancreatic neuroendocrine tumors can alleviate immune suppression. We found that intratumoral IFNγ causes rapid vessel loss, which does not support anti-tumor immunity. In contrast, low-dose TNFα enhances T-cell infiltration and overall survival, an effect that is exclusively mediated by CD8+ effector cells. Intriguingly, lymphocyte influx does not correlate with increased vessel leakiness. Instead, low-dose TNFα stabilizes the vascular network and improves vessel perfusion. Inflammatory vessel remodeling is, at least in part, mediated by tumor-resident macrophages that are reprogrammed to secrete immune and angiogenic modulators. Moreover, inflammatory vessel remodeling with low-dose TNFα substantially improves antitumor vaccination or adoptive T-cell therapy. Thus, low-dose TNFα promotes both vessel remodeling and antitumor immune responses and acts as a potent adjuvant for active immunotherapy.
Relationship between pinworm and urinary tract infections in young girls

Urinary tract infection is particularly common in young girls and Enterobius vermicularis (pinworm) is one of the most prevalent worms found in children worldwide. Young girls, with or without urinary tract infection, were examined for pinworms in order to explore a possible relationship between these two problems. Of the 55 young girls with urinary tract infection, 20 (36.4%) had pinworm eggs in the perianal and/or perineal region monitored using the cellophane tape method, while 9 (16.4%) of 55 young girls who had never previously had a urinary tract infection were found to have Enterobius eggs in at least one of the cellophane tape tests, and the difference was found to be significant (p<0.05). These results suggested that urinary tract infections may be related to pinworms. When a urinary tract infection is diagnosed in young girls, cellulose tape should be applied to both the perianal and the perineal regions on at least three consecutive occasions.
Wave Radiation by Balanced Motion in a Simple Model

We introduce and study a toy model which captures some essential features of wave radiation by slow (or balanced) motion in the atmosphere and the ocean. Inspired by the widely studied five‐component model due to Lorenz, the model describes the coupling of a nonlinear pendulum with linear waves. The waves obey a one‐dimensional linear Klein–Gordon equation, so their dispersion relation is identical to that of inertia‐gravity waves in a rotating shallow‐water fluid. The model is Hamiltonian. We examine two physically relevant asymptotic regimes in which there is some time‐scale separation between the slow pendulum motion and the fast waves: in regime (i), the time‐scale separation breaks down for waves with asymptotically large wavelengths; in regime (ii), the time‐scale separation holds for all wavelengths. We study the generation of waves in each regime using distinct asymptotic methods. In regime (i), long waves are excited resonantly in a manner that is analogous to the Lighthill radiation of sound wav.
A Phospholipase A2-Related Snake Venom (from Crotalus durissus terrificus) Stimulates Neuroendocrine and Immune Functions: Determination of Different Sites of Action.

Immune neuroendocrine interactions are vital for the individual's survival in certain physiopathological conditions, such as sepsis and tissular injury. It is known that several animal venoms, such as those from different snakes, are potent neurotoxic compounds and that their main component is a specific phospholipase A type 2 (PLA2). It has been described recently that the venom from Crotalus durissus terrificus [snake venom (SV), in the present study] possesses some cytotoxic effect in different in vitro and in vivo animal models. In the present study, we investigated whether SV and its main component, PLA2 (obtained from the same source), are able to stimulate both immune and neuroendocrine functions in mice, thus characterizing this type of neurotoxic shock. For this purpose, several in vivo and in vitro designs were used to further determine the sites of action of SV-PLA2 on the hypothalamo-pituitary-adrenal (HPA) axis function and on the release of the pathognomonic cytokine, tumor necrosis factor alpha (TNF alpha), of different types of inflammatory stress. Our results indicate that SV (25 microg/animal) and PLA2 (5 microg/animal), from the same origin, stimulate the HPA and immune axes when administered (i.p.) to adult mice; both preparations were able to enhance plasma glucose, ACTH, corticosterone (B), and TNF alpha plasma levels in a time-related fashion. SV was found to activate CRH- and arginine vasopressin-ergic functions in vivo and, in vitro, SV and PLA2 induced a concentration-related (0.05-10 microg/ml) effect on the release of both neuropeptides. SV also was effective in changing anterior pituitary ACTH and adrenal B contents, also in a time-dependent fashion. Direct effects of SV and PLA2 on anterior pituitary ACTH secretion also were found to function in a concentration-related fashion (0.001-1 microg/ml), and the direct corticotropin-releasing activity of PLA2 was additive to those of CRH and arginine vasopressin; the corticotropin-releasing activity of both SV and PLA2 were partially reversed by the specific PLA2 inhibitor, manoalide. On the other hand, neither preparation was able to directly modify spontaneous and ACTH-stimulated adrenal B output. The stimulatory effect of SV and PLA2 on in vivo TNF alpha release was confirmed by in vitro experiments on peripheral mononuclear cells; in fact, both PLA2 (0.001-1 microg/ml) and SV (0.1-10 microg/ml), as well as concavalin A (1-100 microg/ml), were able to stimulate TNF alpha output in the incubation medium. Our results clearly indicate that PLA2-dependent mechanisms are responsible for several symptoms of inflammatory stress induced during neurotoxemia. In fact, we found that this particular PLA2-related SV is able to stimulate both HPA axis and immune functions during the acute phase response of the inflammatory processes.
Hematologic, cytochemical, ultrastructural, and molecular findings of Hepatozoon-infected flat-headed cats (Prionailurus planiceps).

BACKGROUND The flat-headed cat (Prionailurus planiceps) is a small wild cat of Southeast Asia and is considered extremely endangered. Little is known about the hematologic values, blood cell morphology, or hemoparasites of this species in relation to other Felidae. OBJECTIVES The objective of this study was to report basic hematologic values and describe the light microscopic, cytochemical, and ultrastructural characteristics of blood cells in 2 wild-caught flat-headed cats. In addition, molecular analysis was done of a Hepatozoon organism found in the neutrophils of both cats. METHODS Blood samples were collected into EDTA from the cephalic vein. A CBC, manual differential count, manual reticulocyte count, cytochemical stains (Sudan black B [SBB], alpha-naphthyl acetate esterase [ANAE], and beta-glucuronidase), and scanning and transmission electron microscopy were done using standard methods. RESULTS HCT was slightly lower and reticulocyte counts and red cell distribution width were higher than the expected values for other species of cats. Hepatozoon organisms were found in the cytoplasm of neutrophils in both cats, but the number of infected neutrophils was very low (1%-2%). Neutrophils stained strongly positive for SBB, but were negative for ANAE and beta-glucuronidase. Hepatozoon-infected neutrophils were negative for SBB, but focally positive for ANAE and beta-glucuronidase. By transmission electron microscopy, gamonts of Hepatozoon sp were observed in neutrophils, and rarely free in plasma. Infected neutrophils had fewer specific granules and more mitochondria compared with noninfected neutrophils. PCR products of partial 18S rRNA revealed that the isolate of Hepatozoon in the flat-headed cats was closely related to that of the frog Hepatozoon sp. CONCLUSIONS These results add to our understanding of hematologic values and blood cell morphology in Hepatozoon-infected flat-headed cats as well as the molecular analysis of the Hepatozoon organism, and may be useful for the health management and evaluation of hemoparasitic disease in this species.
Cerebral angiopathy and recurrent strokes following Borrelia burgdorferi infection.

11 to 15% of Borrelia burgdorferi infection. We report a woman who developed an angiopathy with recurrent ischaemic events during 3 years following a tick bite, with Borrelia burgdorferi infection. During spring 1983, this 40 year old woman noticed a tick bite under her left breast, followed by red lesions on the chest and limbs. One year later, she experienced headache associated with weakness and paraesthesia around the mouth and in the left hand. She also complained of vertigo and intermittent dysarthria. She received flunarizine (10mg per day for 3 months) and the symptoms disappeared. In November 1985 she developed a left ataxic hemiparesis, and CT showed a hypodense area in the right lenticular nucleus suggesting infarction. As blood pressure was 170/120
Studies on the specificity of the assay method for the gonadotrophin inhibiting factor.

Summary. The specificity of the assay method for the gonadotrophin inhibiting factor (gif) has been studied in two ways. In the first part ofthe study the biological activity of various gonadotrophin preparations remaining after heating at 100\s=deg\C for 1 hr was measured. In the second part the effect of these hormones on the bio-assay method for the gif was investigated. Following heating it has been shown that most, but not all, of the biological activity of the preparations studied is destroyed when assayed by specific methods. Gonadotrophins derived from ovine pituitary tissue, but not from human urine, have been demonstrated to be capable of causing a uterine response in the assay for the gif. It is concluded that the assay method for the gif is not specific. For this reason care must be taken in interpreting the results of assays of the gif in clinical situations in which high endogenous gonadotrophin levels are likely to be present.
