4) μg/g, 378.52 (183.5-561.1) μg/g, 458.88 (252.5-593, 5) μg/g, and 518.2 (351.6-691) μg/g for the SG, OAGB, SADS, and control groups, respectively. There was a strong inverse correlation between EWL and FE-1 levels at the end of the first year (Spearman's rho = - 0.688, p= 0.003). After having performed PERT for patients with the lowest FE-1 levels, the levels increased to 683.39 (615.5-720) μg/g in the OAGB and 691.5 (643.1-720) μg/g in the SADS groups (p= 0.011).

FE-1 measurements demonstrated that many patients suffer from malabsorption after OAGB or SADS, whereas functions remain normal after SG. PERT corrects pancreatic functions without affecting weight loss and also contributes to the normal serum level of vitamin D.

However, the roles of lncRNAs in the pathogenesis of AD remain unclear. In this study, we aimed to determine the expression of lncRNAs and also mRNAs in AD which may alter expression and contribute to the pathogenesis of the disease. Peripheral blood samples were obtained from patients admitted to the Neurology Department of Pamukkale University Medical Faculty (23 patients with AD, 33 control groups). Total RNA obtained from peripheral blood mononuclear cells (PBMC) of subjects with probable AD (n = 4) and healthy control groups (n = 4) was examined to determine the altered expression of lncRNAs and mRNAs in AD were evaluated by microarray analysis. Five lncRNAs with the highest end-to-end fold change (fc ≥ 2.0, p less then 0.05) were identified and confirmed by quantitative real-time polymerase chain reaction (qRT-PCR). In our study, the profiles of lncRNAs and mRNAs that may be associated with Alzheimer's disease were determined. A total of 14 lncRNAs and 35 mRNAs were determined as upregulated, and 20 lncRNAs and 73 mRNAs determined as downregulated as a result of microarray analysis in patients with AD compared with control groups (fold change ≥ 2.0, p less then 0.05). From lncRNAs, expression of lncRNA TTC39C-AS1, lnc-AL445989.1-2, LINC01420, lnc-CSTB-1, and LOC401557 was confirmed by qRT-PCR. When assessed by KEGG analysis of AD PBMC lncRNA and mRNA profiles, TNF signaling pathway, PI3K/AKT, Ras, and MAPK pathways; glutamatergic, dopaminergic, and cholinergic synapses; GABA, and neurotrophin signaling pathways are found to be significant. This is the first known study to investigate lncRNA profiles in AD PBMCs. We think that these results may open a door to the understanding of AD pathogenesis targeted by lncRNAs.Lyophilization is a pivotal manufacturing process to obtain a stable drug product that is unstable as a ready-to-use formulation. Some formulations may require the addition of drug-specific excipients such as stabilizers, buffers, and bulking agents to support the cake appearance and ensure long-term stability of the drug product. Optimization of the lyophilization process parameters at each stage including freezing and primary and secondary drying is important because these parameters can have a direct impact on the process efficiency (shortened cycle time) and product performance (cake appearance and homogeneous moisture content). Several parameters of the formulation, including properties of the active pharmaceutical ingredient, excipients, solvent system, and container closure, determine the success of lyophilization. Development, scale-up, and transfer of the lyophilization cycle are challenging; hence, a comprehensive understanding of the critical parameters related to the formulation, lyophilization process, and lyophilizer design allows designing a quality drug product. One approach for a successful transfer of the lyophilization cycle between the laboratory and commercial-scale lyophilizer is using vial heat transfer coefficient and ice slab test to establish a maximum sublimation rate. This review provides a general overview of the lyophilization process and discusses several key considerations and product development aspects of formulation, process optimization, container closure system, scale-up principles, and drug product quality attributes from the industrial viewpoint.

Improving the readout for arterial spin labeling with multiple post-labeling delays (multi-PLD ASL) through a flip angle (FA) sweep towards increasing contrast-to-noise ratio for long PLD images.

Images were acquired from 20 healthy subjects and 14 patients with severe, asymptomatic carotid artery stenosis (ACAS) in a 3T MRI scanner. Multi-PLD ASL images with conventional and proposed (FA sweep) readouts were acquired. For patients, magnetic resonance angiography was used to validate the multi-PLD ASL results. Perfusion values were calculated for brain regions irrigated by the main cerebral arteries and compared by analysis of variance.

For healthy subjects, better contrast was obtained for long PLDs when using the proposed multi-PLD method compared to the conventional. For both methods, no hemispheric difference of perfusion was observed. For patients, the proposed method facilitated the observation of delayed tissue perfusion, which was not visible for long PLD using the conventional multi-PLD ASL.

We successfully assessed brain perfusion of patients with asymptomatic CAS using multi-PLD ASL with FA sweep. We were able to show subtle individual differences. Moreover, prolonged arterial transit time in patients was observed, although they were considered asymptomatic, suggesting that it may not be an adequate term to characterize them.

The anti-malaria drug, artesunate, possesses anti-neoplastic potential. Therefore, we aimed to investigate its effect on KSHV-infected PEL cell lines. Artesunate inhibited cell growth and viability of PEL cells, but its effect on peripheral blood mononuclear cells was less pronounced. Artesunate induced G1 phase arrest by downregulating cyclin D1/D2, CDK2/6 and c-Myc. Artesunate increased reactive oxygen species and DNA damage, but did not affect the expression of latent and lytic genes of KSHV. It exhibited cytotoxicity through caspase-dependent and -independent pathways and reduced Bcl-xL, survivin, XIAP and c-IAP1/2 levels. Furthermore, artesunate suppressed NF-κB and AP-1 by inhibiting IκB kinase and IκBα phosphorylation as well as JunB expression. Finally, artesunate treatment attenuated PEL development in mice. Our data support that artesunate is a potential drug for PEL treatment.The leading causes of foodborne viral disease outbreaks are human norovirus and hepatitis A virus (HAV). Their environmental persistence enables contamination of kitchen surfaces and crops often consumed raw, such as berries. Many decontamination procedures are inefficient and unsuitable for surfaces of industrial kitchen environments and soft fruits. In this study, we investigated the efficiency of a novel surface decontamination technology, combining steam and ultrasound (steam-ultrasound). Plastic, steel or raspberry surfaces were spiked with the norovirus surrogate, murine norovirus (MNV), and HAV, and steam-ultrasound treated at 85, 90 and 95 °C for 0-5 s. Post treatment viruses were titrated for survival by plaque assay and for genome stability by real-time quantitative PCR (RT-qPCR) of nucleic acid extracts. Survival of viruses were estimated in a log-linear model and the treatment time requirements for each decimal reduction (D value) in viral survival were calculated. The estimated D values of MNV or HAV were 0.4-0.2 or 1.1-0.8 s on plastic, 0.9-0.7 or 1.4-0.8 s on steel and 1.6-1.7 or 3.2-4.7 s on raspberries. No clear trend of genome reduction was observed with tested treatment parameters. Raspberries treated up to 4 s retained its natural texture and visual appeal similar to untreated controls whilst monitored for 7 days. In conclusion, steam-ultrasound treatment can within seconds reduce the titre of foodborne viruses on surfaces of plastic, steel and raspberries. This may particularly benefit industrial scale production of soft fruits for raw consumption and for swift non-hazardous decontamination of industrial kitchen surfaces.

In order to counter the lack of sufficient kidney donors, there has been interest in expanding the utilization of organs from increased infectious-risk donors. Negative nucleic acid testing of increased infectious-risk organs has been shown to increase their use as compared to only enzyme-linked immunosorbent assay negativity. However, it is not known how the expanded use of nucleic acid testing on a national scale might affect total donor utilization.

The objective of this paper was to determine if a national screening policy requiring the use of nucleic acid testing in both increased infectious-risk and non-increased infectious-risk renal transplant donors would increase the donor organ pool.

This study used decision-tree analysis to determine the cost-effectiveness of four US national screening policies based on an increasingly expansive use of nucleic acid testing for increased infectious-risk and non-increased infectious-risk kidneys. Parameters were taken from the literature. All costs were reported in 2020 US dollars using a Medicare payer perspective and a life-time horizon.

The use of nucleic acid screening solely for increased infectious-risk organs was the dominant strategy. Our results were robust to deterministic and probabilistic sensitivity analyses. One of the main driving factors of cost-effectiveness was the false-positive rate of nucleic acid testing.

Before implementing nucleic acid screening outside of increased infectious-risk organs, its false-positivity rate should be directly studied to ensure that its use does not detrimentally affect transplantation numbers, quality-adjusted life-years, and costs.

Yet, prolonged exposure to prednisone has been associated with certain side effects. This prospective randomized study comparatively assessed the efficacy and safety of short-course high-dose dexamethasone (HDD) and standard prednisone (PDN) as a first-line treatment for children with previously untreated primary ITP. Two hundred eleven children were randomized into the HDD (n = 110) and PDN (n = 101) groups. There was no difference in baseline characteristics between the two groups (p > 0.05). Early response rates were 92.7% and 93% (p = 0.923); initial response rates were 93.6% and 95% (p = 0.658) and durable response rates were 90% and 91% (p = 0.787) in the HDD and PDN groups, respectively. More remission patients in the HDD group compared with the PDN group (86.3% vs. 80.1%) at 12th month after treatment, yet no statistical difference was observed (p = 0.
