A New Species

In the Baltic countries, the golden jackal (Canis aureus) was first recorded in Estonia on 28 February 2013 and three specimens of golden jackal were hunted in Latvia in 2014. The first golden jackal in Lithuania was hunted on 7 February 2015. The species of the golden jackal was identified using morphological and mitochondrial DNA control region (CR1) analysis. In Lithuania, hunting of these animals is permitted throughout the year. Few studies in the past revealed the potential role of the golden jackal as a carrier of intestinal helminths, parasites, and zoonotic diseases. In this study, the presence of tick-borne pathogens and other parasites in golden jackal specimen were investigated. No pathogens (Anaplasma phagocytophilum, Babesia sp., Bartonella sp.) were found in the spleen of the golden jackal. However, the flukes Apophallus donicus, nematodes Uncinaria stenocephala, and unidentified individuals of class Cestoda were detected. Helminths A. donicus and U. stenocephala are not new species for Lithuania and neighbouring territories.

The golden jackalCanis aureusoccurs in south-eastern Europe, Asia, the Middle East, the Caucasus, and Africa. In Serbia, jackals neared extinction; however, during the last 30 years, the species started to spread quickly and to increase in number. Few studies in the past have revealed their potential role as carriers of zoonotic diseases. Animal samples were collected over a three-year period (01/2010–02/2013) from 12 sites all over Serbia. Of the tissue samples collected, spleen was chosen as the tissue to proceed; all samples were tested forLeishmaniaspecies andBrucellaspecies by real-time PCR. Of the 216 samples collected, 15 (6.9%) were positive forLeishmaniaspecies, while four (1.9%) were positive forB. canis. The potential epidemiologic role of the golden jackal in carrying and dispersing zoonotic diseases in Serbia should be taken under consideration when applying surveillance monitoring schemes.

Key Enzyme

: Acid ceramidase (AC), the key enzyme of the ceramide metabolic pathway hydrolyzes pro-apoptotic ceramide to sphingosine, which by the action of sphingosine-1-kinase is metabolized to mitogenic sphingosine-1-phosphate. The intracellular level of AC determines ceramide/sphingosine-1-phosphate rheostat which in turn decides the cell fate. The upregulated AC expression during cancerous condition acts as a “double-edged sword” by converting pro-apoptotic ceramide to anti-apoptotic sphingosine-1-phosphate, wherein on one end, the level of ceramide is decreased and on the other end, the level of sphingosine-1-phosphate is increased, thus altogether aggravating the cancer progression. In addition, cancer cells with upregulated AC expression exhibited increased cell proliferation, metastasis, chemoresistance, radioresistance and numerous strategies were developed in the past to effectively target the enzyme. Gene silencing and pharmacological inhibition of AC sensitized the resistant cells to chemo/radiotherapy thereby promoting cell death. The core objective of this review is to explore AC mediated tumour progression and the potential role of AC inhibitors in various cancer cell lines/models.

Anti Phospholipid Syndrome

Abstract As the coronavirus disease 2019 (COVID-19) pandemic, which is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is spreading rapidly worldwide, it has emerged as a leading cause of mortality, resulting in >1 million deaths over the past 10 months. The pathophysiology of COVID-19 remains unclear, posing a great challenge to the medical management of patients. Recent studies have reported an unusually high prevalence of thromboembolic events in COVID-19 patients, although the mechanism remains elusive. Several studies have reported the presence of aPLs in COVID-19 patients. We have noticed similarities between COVID-19 and APS, which is an autoimmune prothrombotic disease that is often associated with an infective aetiology. Molecular mimicry and endothelial dysfunction could plausibly explain the mechanism of thrombogenesis in acquired APS. In this review, we discuss the clinicopathological similarities between COVID-19 and APS, and the potential role of therapeutic targets based on the anti-phospholipid model for COVID-19 disease.

Eocene Amber

A new species of the extant spider family Anapidae is described from a fossil mature male in Eocene amber from the Baltic region and tentatively assigned to the genus Balticoroma Wunderlich, 2004. Phase contrast X-ray computed micro-tomography was used to reveal important features that were impossible to view using traditional microscopy. Balticoroma wheateri new species is easily diagnosed from all other anapids by having clypeal extensions that run parallel to the ectal surface of the chelicerae and in having the metatarsus of the first leg highly reduced and modified into what is presumably a y-shaped clasping structure. Although only a single extant anapid species occurs in northern Europe, the family was diverse in the Eocene. The discovery of yet another anapid species in Baltic amber supports the idea that Eocene European forests may have been a hotspot of evolution for this family of spiders.

Endogenous Nitric Oxide

Inhaled nitric oxide has been used for 30 years to improve oxygenation and decrease pulmonary vascular resistance. In the past 15 years, there has been increased understanding of the role of endogenous nitric oxide on cell surface receptors, mitochondria, and intracellular processes involving calcium and superoxide radicals. This has led to several animal and human experiments revealing a potential role for administered nitric oxide or nitric oxide donors in patients with systemic inflammatory response syndrome or ischaemia–reperfusion injury, and in patients for whom exposure of blood to artificial surfaces has occurred.

Approximately half of the species in speciose genus Raorchestes were described during the past 10 years, yet only 11 species are known from Southeast Asia and southern China (SEA-SC), adjacent Himalayas, and northeastern India. Field work in northwestern Yunnan province, China resulted in the discovery of one new species in the genus based on morphological and molecular analyses. The new species is diagnosed by small size with 15.0–19.0 mm SVL in adult males (n=3); tongue pyriform, notched posteriorly; rudimentary webbing between toes; fingers and toes with narrow lateral dermal fringes; tibiotarsal articulation reaching anterior of the eye when hindlimb is stretched along the side of the body; relative finger lengths: I < II < IV < III, relative toe lengths: I < II < V < III < IV; inner metatarsal tubercle oval, outer metatarsal tubercle absent; finger discs and toe discs greyish or orange; flank near the crotch with a distinct black region between two creamy white patches, and the thigh having a similar black patch near the groin, proximal to another creamy white patch; a distinct “) (”-shaped dark marking on the back; male with external single subgular vocal sac; nuptial pad absent. A phylogenetic tree was reconstructed based on the mitochondrial genes for 16S rRNA and ND1. The results indicated that these individuals form a monophyletic group, and show high genetic divergence to their closest relatives within the genus (uncorrected p-distances > 3.2%) by distance of 16S comparable to the divergence between recognized Raorchestes species. This study further enriches the diversity of rhacophorids, especially in northwestern Yunnan.

      Estonia, Latvia and Lithuania often tend to be grouped together under the label of ’the Baltic countries’, yet they constitute a region characterised by a diversity which also manifests itself in the field of academic research. Still, it may be possible to detect some common elements in the ecocriticism-related activities that have been taking place in these states during the past couple of decades. The article maps the salient tendencies in the environmental humanities (including ecocriticism) of the region that recently gained an institutionalised platform in the form of the Baltic Conferences on the Environmental Humanities and Social Sciences (BALTEHUMS) that were started in 2018. A survey is given of the three countries’ most significant events and publications that have boasted an ecocritical component, ecocriticism’s institutional representation and inclusion of ecocritical issues in university syllabuses and theory textbooks, as well as some pertinent topics and sub-fields on which the scholars in these countries are currently working. Among these, various aspects of the connections of literature and the ecosystems of the forest (trees) and the mire can be noticed; while also animal studies, literary urban studies, bio- and ecosemiotics and environmental history appear to have entered a fruitful dialogue with ecocritical scholarship currently conducted in the Baltics.
