Complete surgical resection remains the mainstay of the treatment of soft tissue sarcomas. Intraoperative positioning of the patient is dictated by tumor location, whereas preoperative imaging is always performed in the supine position. The effect of changing the patient position on the exact location of the tumor with regard to neurovascular structures and bone is unknown.

Two fresh frozen cadavers (pelvis and legs) were thawed and warmed. Three standardized tumor models were implanted in the thigh and calf. MR/CT images of the cadavers were obtained sequentially in four different patient positions. The minimal distance of each “tumor” to neurovascular structures was measured on axial MR images and the 3D shift of the center of the tumor to the bone was measured after segmentation of the CT images.

A significant difference of the minimal distance of the “tumor” to the femoral artery (P=0.019/0.023) and a significantly greater number of deviations of more than 5mm/10mm in the thigh between the supine position and the other positions compared to two supine positions (p=0.027/0.028) were seen. The center of the “tumor” compared to the bone shifted significantly in the thigh (P<0.001/0.002) but not the lower leg.

Obtaining images in the same patient position as the planned tumor resection may become particularly relevant if computer assisted surgery, which is based on preoperative imaging, is introduced into soft tissue sarcoma surgery as the patient position significantly influences the spatial position of the tumor.

With the ongoing improvements in computational methods and experimental capabilities, genome-scale metabolic models (GEMs) are demonstrating utility in addressing human health applications. The initial areas of highest impact are likely to be health applications where disease states involve metabolic changes. In this review, we focus on recent application of GEMs to studying cancer and the human microbiome by describing the enabling methodologies and outcomes of these studies. We conclude with proposing some areas of research that are likely to arise as a result of recent methodological advances.The Baltic States are the region in Europe where tick-borne encephalitis (TBE) is most endemic, with one-third of the European TBE cases detected in Lithuania, Latvia and Estonia. With the Czech Republic and Germany, Lithuania has among the highest population incidences of TBE. Ticks from the Ixodidae family are the main vectors of the TBE virus (TBEV) in Europe. However, there is still a lack of data on the prevalence of TBEV in ticks in different parts of Lithuania. find more analysed the current prevalence of TBEV in the two most common tick species distributed in Lithuania Ixodes ricinus and Dermacentor reticulatus. Questing I. ricinus (n = 7170) and D. reticulatus (n = 1676) ticks were collected from 81 locations in all ten counties of Lithuania between 2017 and 2019. The presence of TBEV was analysed using a real-time reverse transcription polymerase chain reaction (RT-PCR) and TBEV prevalence in ticks was calculated as the minimum infection rate (MIR). TBEV was detected in the three developmental stages (adults, nymphs and larvae) of I. ricinus and in D. reticulatus adults. The MIR of TBEV in the total sample of I. ricinus was 0.4 % (28/7170) and for D. reticulatus was also estimated to be 0.4 % (6/1676). TBEV-infected ticks were found in 16 locations in seven counties, with MIR ranging from 0.1 % to 1.0 %. The TBEV strains detected belong to the European subtype. To the best of the authors’ knowledge, this is the first report on the prevalence of TBEV in unfed D. #link# reticulatus ticks and in I. ricinus unfed larvae in Lithuania.The evolution and phylogenetic relationships of the ticks at both the family and genus levels are contested. The genus Amblyomma and its subgenera are in a state of flux; moreover, the relationships among the three tick families are controversial due to conflicting phylogenetic support for different arrangements of the three families of living ticks. With 18 newly sequenced mitochondrial (mt) genomes of ticks included, we executed the largest mt genome phylogenetic study of ticks so far. Phylogenetic trees were inferred from one sea spider mt genome, one horseshoe crab, five mite mt genomes and 146 tick mt genomes from 120 species 153 mt genomes in total. Sixteen phylogenetic trees were inferred from 10 datasets using both maximum likelihood and Bayesian inference methods. We describe the first novel mt gene-arrangement for the metastriate Ixodidae in Amblyomma (Africaniella) transversale. Also, three unusual partial 16S rRNA gene inserts were found in the mt genome of Haemaphysalis (Alloceraea) kitaokai we consider the possible role of past genome translocation events in the formation of these inserts. Our phylogenies revealed evidence that (i) the genus Amblyomma is polyphyletic with respect to Amblyomma (Africaniella) transversale; (ii) the subgenus Aponomma is apparently embedded in the genus Amblyomma; (iii) Haemaphysalis (Segalia) parva and Haemaphysalis (Alloceraea) kitaokai form a clade to the exclusion of other Haemaphysalis species; and (iv) the phylogenetic position of the family Nuttalliellidae is unstable among phylogenies from different datasets.Cryptosporidium and Toxoplasma are parasites that have caused problems worldwide. Cryptosporidium causes severe watery diarrhoea and may be fatal in immunocompromised patients and in infants. Nitazoxanide is the only agent currently approved by the FDA, but its efficacy is limited. Toxoplasmosis is also a problem in the immunocompromised, as currently available treatment options have limited efficacy and patient tolerance can be poor. In the present investigation, we screened libraries of epigenetic compounds to identify those that inhibited C. parvum growth. Nullscript was identified as a compound with an inhibitory effect on C. parvum and T. gondii growth, and was less toxic to host cells. Nullscript was also able to significantly decrease oocyst excretion in C. parvum-infected SCID mice.
