Furthermore, cytotoxic effect of the prepared nanocomposite was found to be statistically insignificant in comparison with the pristine PHB. A four-fold increase in the shelf life was demonstrated by a simulation study conducted using moisture and oxygen-sensitive food items (potato chips and milk product). V.BACKGROUND Hyperthyroidism is characterized by excess hormone secretion from the thyroid gland. Anti-thyroid drugs (ATDs), surgery, and radioactive iodine can be used in treatment. Plasmapheresis is a rapid and effective treatment option in cases where rapid euthyroidism is needed to be obtained due to complications of thyrotoxicosis and major adverse effects of ATDs. MATERIAL AND METHOD We present patients receiving plasmapheresis to provide immediate euthyroidism due to severe hyperthyroidism, adverse effects of ATDs, or non-thyroid surgery from January 2012 to December 2016. RESULTS This study included 18 patients. The etiology of hyperthyroidism was TDG in seven patients, TDMNG in two, TA in two, TMNG in four, and one patient had AIT. Plasmapheresis was performed to achieve euthyroidism before surgery in two patients. The mean plasmapheresis session was 5.35. The mean number of sessions needed for patients with TDG and TDMNG was 4, whereas it was 6.5 for patients with TA and TMNG (p = 0.07). The decrease of mean free thyroxine and free triiodothyronine were 57 % and 73 %, respectively (p less then 0.001). After plasmapheresis, total thyroidectomy was performed in 14 patients. Euthyroidism was achieved with RAI in one patient and with medical therapy in three patients. CONCLUSIONS Plasmapheresis therapy is a reliable and effective treatment option for patients who cannot use ATDs because of their adverse events and those with hyperthyroidism that does not resolve with these drugs, or to achieve euthyroidism before total thyroidectomy, RAI or non-thyroid emergency surgery. However, it cannot be used widely because it is expensive and invasive. Highly pathogenic influenza H7N9 viruses that emerged in the fifth wave of H7N9 outbreak pose a risk to human health. The World Health Organization has updated the candidate vaccine viruses for H7N9 viruses recently. In this study, we evaluated the immune response to an updated H7N9 candidate vaccine virus, which derived from the highly pathogenic A/Guangdong/17SF003/2016 (GD/16) in mice and rhesus macaques. GD/16 vaccination elicited robust neutralizing, virus-specific immunoglobulin G antibodies and effective protection, but poor hemagglutination inhibition antibody titers. Furthermore, mouse and rhesus macaque serum raised against the previous H7N9 CVV A/Anhui/1/2013 (AH/13) were tested for its cross-reactivity to GD/16 virus. We found that although AH/13-immune serum has poor hemagglutination inhibition reactivity against GD/16 virus, AH/13 elicit efficient cross-neutralizing antibodies and in vivo protection against GD/16. Further studies showed that the hemagglutinin of GD/16 has strong receptor binding avidity, which might be associated with the decreased hemagglutination inhibition assay sensitivity. This study underscores the point that receptor binding avidity should be taken into account when performing quantitative interpretation of hemagglutination inhibition data. A combination of multiple serological assays is required for accurate vaccine evaluation and antigenic analysis of influenza viruses. The prevalence of early-stage lung adenocarcinoma (LUAD) has increased alongside increased implementation of lung cancer screenings. Robust discrimination criteria are urgently needed to identify those patients who might benefit from additional systemic therapy. Here, to develop a reliable, individualized immune gene-set-based signature to predict recurrence in early-stage LUAD, a novel recurrence-associated immune signature was identified using a least absolute shrinkage and selection operator model, and a stepwise Cox proportional hazards regression model with a training set comprised of 338 early-stage LUAD samples form TCGA, which was subsequently validated in 226 cases from GSE31210 and an independent set of 68 frozen tumor samples with qRT-PCR data. This new classification system remained strongly predictive of prognoses across clinical subgroups and mutation status. Further analysis revealed that samples from high-risk cases were characterized by active interferon signal transduction, distinctive immune cell proportions and immune checkpoint profiles. Moreover, the signature was identified as an independent prognostic factor.

Hypoxia is a key feature of solid tumors, associated with disease aggressiveness and poor outcome. Besides undergoing broad intracellular molecular and metabolic adaptations, hypoxic tumor cells extensively communicate with their microenvironment to concoct conditions favorable for their survival, growth and metastatic spread. This mode of communication is through diverse secretory factors including exosomes (extracellular vesicles of endosomal origin and ~30-150 nm in diameter) which could carry package of molecular information including proteins, nucleic acids, lipids, and metabolites wrapped in lipid bilayer. Numerous studies have concluded that hypoxia promotes exosomes secretion by cancer cells. Moreover, exosomal cargo is considerably altered under hypoxia, dictating tumor cells communication with its local and distant microenvironment. In this review, we have summarized the effects of hypoxia on exosomes (ExoHypoxic) secretion and cargo sorting (miRNAs, proteins, lipids and metabolites) as well as their biological effects in local and distant microenvironment. We have described the key molecular mechanisms (e.g. HIF-1α, ceramides, RAB GTPases, tetraspanins, oxidative stress etc) involved in the production of ExoHypoxic. Lastly, we have highlighted the potential usefulness of ExoHypoxic in cancer prognosis as well as therapeutic opportunities in targeting ExoHypoxic.
