01) can be explained by seasonal short-range migrations. Otoliths shape differences between MRS and FRS (ANOVA-like, P  less then  0.01) suggest that P. pagrus does not form a homogeneous group in southern Brazil.Here we describe a successful surgical management of a distal fibular fracture combined with a tarsocrural luxation and multiple metatarsal fractures in the left foot of a southern brown howler monkey (Alouatta guariba clamitans). We achieved satisfactory outcome by applying intramedullary pinning for each of the bone fractures and closed reduction of joint luxation-kept in place only by bone alignment, without further ligament reconstruction. Bone healing occurred uneventfully within eight weeks and the monkey's foot regained its normal function. Therefore, we could properly release the patient back into the wild.Nest building relates to reproductive effort, sexual selection, intersexual conflict and cooperation and may be linked to individual phenotype and interindividual interactions. Guanosine 5'-monophosphate compound library chemical In particular, larger individuals having more energy reserves are expected to build more, larger nests, without having to trade intrasexual competition for cooperative nest building. Capture-mark-recapture and nest survey of sea lamprey (Petromyzon marinus L. 1758) were combined to assess the relationship between individuals and nesting activity on a spawning ground, throughout a breeding season, during which 202 nests were observed and 114 individuals were captured. On average, males and females stayed 8.33 ± 1.02 and 3.57 ± 1.04 days on the spawning ground, visited 2.26 ± 1.72 and 1.67 ± 1.17 nests and encountered 2.33 ± 2.13 mates for males and 2.29 ± 1.32 mates for females, respectively, and the number of mates encountered increased with the number of nests visited. Body size had no effect on the duration of presence on spawning ground, number of nests visited, number of individuals per nest and sex ratio on nest or nest volume. Bigger nests were found at the end of the season and were not necessarily built by more individuals. This work brings insights on the mating system and cooperative nest building in sea lamprey and may inform managers who want to estimate sea lamprey populations via nest surveys.
To understand the impact of the COVID-19 pandemic on the hospice and palliative workforce and service delivery.

This was a cross-sectional survey of 36 hospice and palliative care workforce members representing all United States geographic regions.

Most respondents (70%) reported an increase in specific palliative care services as a result of the pandemic. Two thirds (78%) of respondents reported their agency has cared for confirmed COVID-19 patients. Only half reported the agency had access to laboratory facilities for surveillance and detection of outbreaks in both patients and staff (58%) and that the agency could test patients and providers for COVID-19 (55%). Qualitative comments described the impact of the pandemic and resulting social distancing measures on the emotional well-being of patients, families, and staff.

Our findings suggest that the COVID-19 pandemic has strained the palliative and hospice care workforce as it provides increased services at an unprecedented rate to patients and families. The implications of these findings are important for public health nurses who are skilled in disaster management and quickly responding to emergencies. The expertise of public health nurses can be leveraged to support palliative care agencies as they strive to manage the pandemic in the communities they serve.

The recent development of technologies that allow control of the timing of neurobiological events such as gene expression and neuronal firing enable the fruitful application of SCEDs for the study of brain-behavior relations. There are at least 3 benefits expected from applying SCEDs to study how neurobiological events affect behavior. First, SCEDs entail direct within- and across-subject assessments of reliability, likely increasing the probability of replication across studies and encouraging a search for the causes of replication failure when they occur. Second, SCEDs focus on behavior in individual organisms producing a body of knowledge that applies to individuals rather than population parameters. Finally, SCEDs require fewer animals, decreasing costs and effort and addressing the ethical obligation to reduce the number of animals used for research. Examples are provided using hypothetical data generated based on published research. Collaborations between behavior analysts and behavioral neuroscientists will bring the world within the skin under direct experimental control and broaden our understanding of the determinants of behavior.A growing deer antler contains a stem cell niche that can drive endochondral bone regeneration at up to 2 cm/day. Pleiotrophin (PTN), as a multifunctional growth factor, is found highly expressed at the messenger RNA level within the active antler stem cell tissues. This study aims to map the expression patterns of PTN protein and its receptors in a growing antler and investigate the effects of PTN on antler stem cells in vitro. Immunohistochemistry was employed to localise PTN/midkine (MDK) and their functional receptors, protein tyrosine phosphatase receptor type Z (PTPRZ), anaplastic lymphoma kinase (ALK), NOTCH2, and integrin αV β3, on serial slides of the antler growth centre. PTN was found to be the dominantly expressed growth factor in the PTN/MDK family. High expression of PTPRZ and ALK co-localised with PTN was found suggesting a potential interaction. The high levels of PTN and PTPRZ reflected the antler stem cell activation status during the regenerative process. When antler stem cells were cultured in vitro under the normoxic condition, no PTN protein was detected and exogenous PTN did not induce differentiation or proliferation but rather stem cell maintenance. Collectively, the antler stem cell niche appears to upregulate PTN and PTPRZ in vivo, and PTN-PTPRZ signalling may be involved in regulating antler stem cell behaviour during rapid antler regeneration.Mutations in more than 150 genes are responsible for inherited hearing loss, with thousands of different, severe causal alleles that vary among populations. The Israeli Jewish population includes communities of diverse geographic origins, revealing a wide range of deafness-associated variants and enabling clinical characterization of the associated phenotypes. Our goal was to identify the genetic causes of inherited hearing loss in this population, and to determine relationships among genotype, phenotype, and ethnicity. Genomic DNA samples from informative relatives of 88 multiplex families, all of self-identified Jewish ancestry, with either non-syndromic or syndromic hearing loss, were sequenced for known and candidate deafness genes using the HEar-Seq gene panel. The genetic causes of hearing loss were identified for 60% of the families. One gene was encountered for the first time in human hearing loss ATOH1 (Atonal), a basic helix-loop-helix transcription factor responsible for autosomal dominant progressive hearing loss in a five-generation family. Our results show that genomic sequencing with a gene panel dedicated to hearing loss is effective for genetic diagnoses in a diverse population. Comprehensive sequencing enables well-informed genetic counseling and clinical management by medical geneticists, otolaryngologists, audiologists, and speech therapists and can be integrated into newborn screening for deafness.Tetrahydroxy stilbene glycoside (TSG) is a main active compound in Polygonum multiflorum. Acetaminophen (APAP) is a well-known analgesic and antipyretic drug. It is considered to be safe within a therapeutic range, in case of acute intoxication hepatotoxicity occurs. This present study aims to observe TSG-provided alleviation on APAP-induced hepatoxicity in C57BL/6 mice. APAP performs extensive necrosis and dissolves nucleus suggesting liver damage from hepatic histopathology. Serum alanine aminotransferase, aspartate aminotransferase, lactate dehydrogenase, and alkaline phosphatase analysis and liver histological evaluation showed that TSG reduced the hepatotoxicity induced by a toxic dose of APAP. Moreover, TSG alone had no hepatotoxicity. TSG eliminated hepatic glutathione depletion and cysteine adducts formation. It also reduced the expression of interleukin-10 and lowered the production of reactive oxygen species in liver tissues. Luminex was used to detect cytokine production in different groups. Herein, we used an untargeted metabolomics approach by performing ultrahigh-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry on treated mice to identify metabolic disruptions under APAP and TSG. Major alterations were observed for purine metabolism, amino acid metabolism, and fatty acid metabolism. These data provide metabolic evidence and biomarkers in the liver that the ABC transporters, Glycine serine and threonine metabolism, and Choline metabolism in cancer changed the most. These targets of metabolites have the potential to improve our understanding of homeostatic. Meanwhile, these metabolites revealed that TSG can alleviate inflammation caused by APAP and promote the activity of intrinsic antioxidants. In summary, TSG can regulate lipid metabolism, promote the production of antioxidant enzymes, and decrease the inflammatory response.Many species show territoriality, in which territory owners have exclusive or priority use of a region. In humans, tolerance of others within our space also depends greatly on our social relationships with them. This has been hypothesized as one potential driver of the evolution of long-term, inter-group relationships, through enabling shared access of resources and easing disputes over space. However, extremely little is known about the importance of social relationships between neighbouring groups in non-humans for how space is used and shared. Using 16 years of data on the simultaneous movement and interaction patterns of 17 mountain gorilla groups, we investigated how the occurrence of aggressive and affiliative behaviour during inter-group encounters was influenced by both their social and spatial context. We found evidence of territorial defence, with rates of aggression increasing towards the centre of home ranges. Groups which had previously split from each other showed higher levels of affiliation during encounters with each other and experienced lower levels of aggression when within the other's peripheral home range. However, encounters within core areas of the home range consistently elicited higher aggression, regardless of the groups' history. Our findings indicate that not only are the social relationships between groups retained after they split from one another but also that these relationships enable groups to access certain areas with a reduced risk of aggression. This suggests that reduced aggression when accessing areas within neighbours' home ranges may be an advantage for the maintenance of inter-group relationships and a potential driver in the evolution of long-term, post-dispersal relationships and complex multi-level societies.
