Christine Elizabeth Cooper, Philip Carew Withers
'Insensible' evaporative water loss of mammals has been traditionally viewed as a passive process, but recent studies suggest that insensible water loss is under regulatory control, although the physiological role of this control is unclear. We test the hypothesis that regulation of insensible water loss has a thermoregulatory function by quantifying for the first time evaporative water loss control, along with metabolic rate and body temperature, of a heterothermic mammal during normothermia and torpor. Evaporative water loss was independent of ambient relative humidity at ambient temperatures of 20 and 30°C, but not at 25°C or during torpor at 20°C...

Introduction: Mucus extravasation cyst is a commonly occurring lesion in oral cavity that may result from traumatic severance of a salivary gland duct with subsequent extravasation of mucus into fibrous connective tissue. After a conventional excision or marsupialization, recurrence is not uncommon. Diode laser offers an effective modality for management of such lesions. Case Reports: Four patients were referred with painless fluctuant swellings on labial and buccal mucosa. After recording history and clinical examination, provisional diagnosis of mucocele was made...

Many proteins contain tandemly repeated modules of several amino acids, which act as the building blocks that form the underlying architecture of a specific protein-binding interface. Among these motifs and one of the most frequently observed is ankyrin repeats (ANK), which consist of 33 amino acid residues that are highly conserved. ANK domains span a wide range of functions, including protein-protein interactions, such as the recruitment of substrate to the catalytic domain of an enzyme, or the assembly of stable multiprotein complexes...

Decompression has been considered a valuable tool for odontogenic cystic lesions to minimize cyst size with low morbidity and recurrence. However, whether decompression has a role in regulating stem cell properties of orofacial bone marrow stromal cells (BMSCs) around the cysts has not been fully investigated. The present study compared the stem cell marker profile and osteogenic differentiation potential of orofacial BMSCs prior to and following marsupialization (pre‑BMSCs vs. post‑BMSCs) in the same individuals...

We investigated the karyotype of 18 didelphid species captured at 13 localities in the Brazilian Amazon, after conventional staining, C-banding, Ag-NOR and fluorescent in situ hybridization (FISH) using the 18S rDNA probe. Variations were found in the X chromosome, heterochromatin distribution and the 18S rDNA sequence. The main variation observed was in the position of the centromere in the X chromosome of Caluromys philander Linnaeus, 1758 and Marmosa murina Linnaeus, 1758. For both species, the X chromosome showed a geographical segregation in the pattern of variation between eastern and western Brazil, with a possible contact area in the central Amazon...

Contraception has an established role to play in managing overabundant populations and preventing undesirable breeding in zoos. We propose that it can also be used strategically and selectively in conservation management programs to increase the genetic and behavioural quality of the animals. In captive breeding programs, it is becoming increasingly important to maximise the retention of genetic diversity by managing the reproductive contribution of each individual, and preventing genetically suboptimal breeding, through the use of selective contraception...

Nedal Abu-Mostafa, Arshad Abbasi
The dentigerous cyst (DC) is the most common type of developmental odontogenic cyst. It is usually asymptomatic and associated with the crown of an unerupted or impacted tooth. However, after a long duration, it is likely to cause significant bone resorption, cortical expansion, and tooth displacement. This report presents a large infected DC in the mandible of a 12-year-old female patient. The DC was located inferior to badly decayed primary molars and surrounded three impacted permanent teeth: canine, first premolar, which had a dilacerated root, and second premolar...

AIMS: Conservative treatment of jaw cysts establishes low surgical complication risk and protects vital anatomical structures such as inferior alveolar nerve, maxillary sinus and permanent tooth germs. Marsupialization and decompression have been widely used in children. The aim of this study was to evaluate the results of the conservative treatment of jaw cysts in five children. MATERIALS AND METHODS: This article presents case series of marsupialization in jaw cysts associated with impacted teeth in five children...

Regulating maternal immunity is necessary for successful human pregnancy. Whether this is needed in mammals with less invasive placentation is subject to debate. Indeed, the short gestation times in marsupials have been hypothesized to be due to a lack of immune regulation during pregnancy. Alternatively, the maternal marsupial immune system may be unstimulated in the absence of a highly invasive placenta. Transcripts encoding pro-inflammatory cytokines were found to be overrepresented in the whole uterine transcriptome at terminal pregnancy in the opossum, Monodelphis domestica To investigate this further, immune gene transcripts were quantified throughout opossum gestation...

The thylacine (Thylacinus cynocephalus), one of Australia's most characteristic megafauna, was the largest marsupial carnivore until hunting, and potentially disease, drove it to extinction in 1936. Though thylacines were restricted to Tasmania for two millennia prior to their extinction, recent "plausible" sightings on the Cape York Peninsula in northern Queensland have emerged, leading some to speculate the species may persist, undetected. Here we show that the continued survival of the thylacine is entirely implausible based on most current mathematical theories of extinction...

Genetic rescue has now been attempted in several threatened species, but the contribution of genetics per se to any increase in population health can be hard to identify. Rescue is expected to be particularly useful when individuals are introduced into small isolated populations with low levels of genetic variation. Here we consider such a situation by documenting genetic rescue in the mountain pygmy possum, Burramys parvus. Rapid population recovery occurred in the target population after the introduction of a small number of males from a large genetically diverged population...

From the Miocene Sahelanthropus tchadensis to Pleistocene Homo sapiens, hominins are characterized by a derived anterior position of the foramen magnum relative to basicranial structures. It has been previously suggested that the anterior position of the foramen magnum in hominins is related to bipedal locomotor behavior. Yet, the functional relationship between foramen magnum position and bipedal locomotion remains unclear. Recent studies, using ratios based on cranial linear measurements, have found a link between the anterior position of the foramen magnum and bipedalism in several mammalian clades: marsupials, rodents, and primates...

The first sign of mammalian germ cell sexual differentiation is the initiation of meiosis in females and of mitotic arrest in males. In the mouse, retinoic acid induces ovarian Stra8 expression and entry of germ cells into meiosis. In developing mouse testes, cytochrome P450 family 26, subfamily b, polypeptide 1 (CYP26B1) produced by the Sertoli cells degrades retinoic acid, preventing Stimulated by Retinoic Acid Gene 8 (Stra8), expression and inhibiting meiosis. However, in developing humans, there is no evidence that CYP26B1 acts a meiosis-inhibiting factor...

BACKGROUND: Spinal extradural arachnoid cysts (SEAC) are relatively uncommon. However, several large cysts have presented with spinal cord compression requiring surgical intervention. CASE DESCRIPTION: We report a patient with progressively enlarging SEAC causing worsening right S1 radiculopathy and gastrocnemius muscle atrophy. Electromyography (EMG) and nerve conduction studies (NCS) revealed an S1 motor radiculopathy. Serial magnetic resonance imaging (MRI) findings confirmed enlargement of the small cyst originating from the sacral thecal sac on the right while two smaller cyst on the left remained stable...

A fundamental challenge in resolving evolutionary relationships across the Tree of Life is to account for heterogeneity in the evolutionary signal across loci. Studies of marsupial mammals have demonstrated that this heterogeneity can be substantial, leaving considerable uncertainty in the evolutionary timescale and relationships within the group. Using simulations and a new phylogenomic data set comprising nucleotide sequences of 1550 loci from 18 of the 22 extant marsupial families, we demonstrate the power of a method for identifying clusters of loci that support different phylogenetic trees...
