Neglected tropical diseases (NTDs) are a group of pathologies caused by infectious agents or parasites, including the protozoa Leishmania sp. and Trypanosoma cruzi, which cause leishmaniasis and Chagas disease, respectively. The complications of the treatment regimen indicate the urgent need to search for new strategies and therapeutic agents. Among these is the essential oil of Psidium myrsinites DC. The essential oil of the leaves (PMEO) was evaluated in vitro, and cytotoxic activity was analysed against promastigotes of Leishmania braziliensis and Leishmania infantum and epimastigotes of Trypanosoma cruzi, as well as mammalian cells. The results showed that the PMEO had relevant activity against L. braziliensis, low cytotoxicity and a high selectivity index SI = 6.6. These results suggest that PMEO has antiparasitic potential against L. braziliensis, making this species is a possible alternative therapeutic source, given its effectiveness in the in vitro tests performed, opening the possibility of new biological studies in vivo.Macadamia integrifolia Maiden & Betche is cultivated around the world for its highly valued nuts (macadamia nuts). Although the chemical composition of the edible macadamia oil has been repeatedly investigated, other plant organs have not been phytochemically or biologically assessed. In this study, ethanolic extract of M. integrifolia leaves was phytochemically investigated which led to the isolation of 6 compounds. Two functional galactolipids, i.e., monogalactosyl diacylglycrol 364 (MGDG 364), digalactosyl monoacylglycerol 182 (DGMG 182), gallic acid and protocatechuic acid were identified in the genus Macadamia for the first time, in addition to the cyanogenic glycoside dhurrin and β-sitosterol. Additionally, anti-tyrosinase activity of the extract, its fractions and isolated compounds was investigated and a good tyrosinase inhibitory activity was observed for the extract, IC50=85 µg/mL and its polar fractions (ethyl acetate at 60 µg/mL and n-butanol at 75 µg/mL), with gallic acid showing strong anti-tyrosinase activity at IC50 56 µg/mL.
The aim of this study is to analyze whether soluble fms-like tyrosine kinase-1 (sFlt-1) can be correlated with the severity of PE.

This study was conducted in a single hospital and is a prospective, observational study. sFlt-1 was measured at the diagnosis of preeclampsia. The period from diagnosis to pregnancy termination (pregnancy prolongation periods) was defined as the barometer for the severity of PE. The correlations between sFlt-1 level with pregnancy prolongation periods were then analyzed.

Eighteen pregnant women diagnosed with early-onset preeclampsia were recruited. sFlit-1 value significantly negatively correlated with the pregnancy prolongation period from diagnosis (
 = .003,
 = 0.647).

sFlt-1 was correlated with the pregnancy prolongation periods after onset of PE. sFlt-1 in early-onset PE may reflect the severity of PE in pregnant women.

Their structures including absolute configurations were elucidated by extensive spectroscopic data and electronic circular dichroism (ECD) analyses. Compounds 4 and 6 showed significant cytotoxicity against A549, HCT-116, MDA-MB-231, PC-3 and HeLa with IC50 values from 2.25 to 8.97 µM. Compounds 1, 2 and 7 also displayed good cytotoxicity against HCT-116, MDA-MB-231 and PC-3 with IC50 values from 1.26 to 8.32 µM. This is the first time to report the isolation and bioactivity evaluation of chemical constituents from C. yunnanensis.Adeno-associated virus (AAV)-based gene therapy offers a new treatment option for individuals with haemophilia. The results of earlier AAV-based trials using AAV2-human Factor IX (hFIX) gene for the treatment of patients with haemophilia B (HB) demonstrated limited efficacy possibly because of pre-existing neutralizing antibodies against the capsid limiting target tissue transduction and expression of hFIX. Even relatively low titers of AAV neutralizing antibodies (NAb) from natural AAV infections against the capsid have been shown to inhibit transduction of intravenously administered AAV in animal models and were associated with limited efficacy in human trials. C75 datasheet Thus, in the gene therapy field, primary eligibility for enrolment in the clinical administration of AAV is an important issue for prior screening of potential candidates for optimal therapeutic protein expression over time. Furthermore, success depends on accurate assessment of pre-existing AAV-specific neutralizing antibodies in the selected cohort for determining efficacy, safety and ethical considerations. Current techniques to screen AAV-antibodies are transduction inhibition assay (TIA) for neutralizing antibodies and AAV capsid ELISA for total antibodies. This study developed and screened for total capsid binding anti-AAV3 antibodies using ELISA and determined neutralizing antibody levels by TIA using mCherry flow cytometry in healthy and individuals with hemophilia B in India. One hundred and forty-three apparently healthy controls and 92 individuals with hemophilia B were screened. The prevalence of total and neutralizing antibody in healthy controls were 79.7% and 65% respectively and the prevalence of total and neutralizing antibody in hemophilia B patients for AAV3 was 92.4% and 91.3% respectively.
To explore differences of apathy perfusion correlates between Alzheimer's disease (AD) and Frontotemporal dementia (FTD) using perfusion SPECT.

We studied 75 FTD and 66 AD patients. We evaluated apathy using Neuropsychiatric Inventory (NPI). We compared perfusion of BAs on left (L) and right (R) hemisphere in AD and FTD.

Apathy in AD was significantly and negatively correlated with dorsolateral prefrontal cortex bilaterally, right anterior prefrontal cortex, inferior frontal cortex bilaterally, especially on the right, orbital part of inferior frontal gyrus bilaterally, left dorsal anterior cingulate cortex, right primary and secondary visual cortex, and with bilateral anterior and dorsolateral prefrontal cortex, inferior frontal cortex and orbital part of inferior frontal gyrus, bilaterally, bilateral anterior -ventral and dorsal- cingulate cortex, left posterior ventral cingulate cortex, right inferior, middle and anterior temporal gyri, entorhinal and parahippocampal cortex in FTD.

Significant overlapping of apathy perfusion correlates between AD and FTD is seen in frontal areas and anterior cingulate.
