Due to the COVID-19 pandemic, governments of many countries announced regulations to prevent the virus from spreading. For people with a disability living in a sheltered care facility in the Netherlands, this meant that they were not able to receive any visitors for almost 3 months.
This study examines how people with an intellectual and visual disability and their families experienced the period in which it was mandated not to have any physical contact. The aim is to examine the experiences of this target group and gain insight in the way measures were taken in order to be able to advise care organizations about adequate care with respect to possible restrictive measures in the future.
In-depth interviews were conducted with two groups of people (1) fourteen people with an intellectual and visual disability, living in sheltered care facilities and (2) twelve people being relatives of residents of these same sheltered care facilities. In the interviews, the participants were questioned about their experacilities and the government; (2) the relation with family and friends; and (3) the consequences of COVID-19 and the regulations. Both relatives and residents were understanding of the difficult situation, but also expressed criticism about the chosen regulations, the communication thereof, and the practical implementation. learn more Both groups have experienced the interruption of close contact as emotional and difficult. However, also positive consequences of the restrictions due to COVID-19 were mentioned. The results provide a list of recommendations for sheltered care facilities.
The preponderance of microbial infections remains a global challenge. In the present study, synthesis of novel cysteine-based antimicrobial agents and their biological evaluation is reported.
The reaction of
-toluenesulphonyl chloride with cysteine afforded 2-[(4-methylphenyl)sulphonyl]amino-3-sulphanylpropanoic acid

Imbalance in blood levels of trace elements is independent risk factor for metabolic syndrome (MetS), type 2 diabetes mellitus (T2DM), and its complications. This study investigated plasma and erythrocyte levels of copper, magnesium, zinc, and their correlations with biochemical components of the MetS in T2DM patients compared to the healthy controls.
Forty men recently diagnosed T2DM with MetS without complications and thirty six age-matched healthy controls were enrolled in this cross-sectional study. Plasma and erythrocyte levels of selected elements were measured by graphite furnace atomic absorption spectroscopy.
The results of the present study showed significantly lower plasma levels of copper, magnesium, and zinc and lower erythrocytes copper in the patients' group compared to the controls; while erythrocyte levels of magnesium and zinc were not significantly different between the two groups. Significant negative correlations were observed between plasma levels of copper with waist and hip circu.
Glioblastoma multiforme (GBM) is the most invasive type of cancer which starts inside the brain. GBM cells were found to have similar properties to glioblastoma cancer stem cells. CD44 can be used as a marker of the cancer stem cells in a subset of glioblastoma tumor cells. Recent studies showed that CD44 is involved in developing cancer cells via the protein kinase B (PKB or AKT) signaling pathway. Therefore, this study aimed to investigate the CD44 mRNA silencing effects on the glioblastoma cell cycle via AKT signaling pathway.
To determine CD44 expression in the samples of the patients with GBM, we used the analysis of data extracted from TCGA database. qRT-PCR and western blotting were used to evaluate the expression level of genes and proteins. Different cell cycles were evaluated by DAPI staining and flow cytometry.
Bioinformatics results showed that CD44 expression level in GBM tumor samples is higher than in normal samples. Effects of poly (ethylene imine)-polyethylene glycol (PEI-PEG)-loaded CD44 siRNA in cell cycle showed that CD44 silencing could inhibit cell cycle in G0-G1 phase by more than 20% compared to the negative control (
< 0.05). Furthermore, PEI-PEG-loaded CD44 siRNA reduces the expression of cyclin D1 and CKD-4. According to our findings, this structure also prevented AKT phosphorylation at Thr-308 and Ser-473.
Our results suggest that PEI-PEG-loaded CD44 siRNA may attenuate the cell cycle by suppressing AKT signaling pathway.

Insulin resistance (IR) can negatively affect clinical outcomes in acute ischemic stroke (IS) patients. Safe and cost-saving interventions are still needed to improve glycemic indices in this population. The primary objective was to evaluate L-carnitine (LC) effects in acute IS patients' homeostatic model assessment of IR (HOMA-IR).
In this randomized, double-blind placebo-controlled clinical trial, critically ill IS patients were allocated to receive daily oral L-carnitine (1.5 g) or a placebo for six days. Fasting serum levels of glucose, insulin, C-reactive protein, LC, and HOMA-IR were measured on days 1 and 7. Mechanical ventilation duration, ICU/hospital duration, illness severity score, sepsis, and death events were assessed.
Forty-eight patients were allocated to the research groups, 24 patients in each group, and all were included in the final analysis. LC administration showed a decrease in mean difference of HOMA-IR and insulin levels at day 7 compared to placebo, -0.94 ± 1.92
0.87 ± 2.24 (
= 0.01) and -2.26 ± 6.81
0.88 ± 4.95 (
= 0.03), respectively. However, LC administration did not result in significant improvement in clinical outcomes compared to placebo. The short duration of intervention and low sample size limited our results.
Supplementation of L-carnitine improved HOMA-IR index in acute IS patients admitted to the critical care unit. Supplementation of LC would be a potential option to help to control IR in critically ill acute IS patients.

Antiplatelet agents can diminish the chance of coronary heart diseases due to the prevention of unusual clotting in the arteries by inhibiting platelet aggregation and avoiding the formation of a blood clot. This mechanism can help to prevent ischemic stroke likewise. To improve the activity of these drugs and reduce their side effects, further studies are required.
Based on the previous studies representing the promising antiplatelet activity of indole hydrazones, a series of their homologs containing twenty-one compounds were prepared in two steps. First, alkylation reaction on the nitrogen of the indole ring, and second, chiff base formation by condensation of a primary amine and N-substituted indole-3 carbaldehyde. Consequently, their platelet anti-aggregation activity was evaluated based on the Born turbidimetric method.
Most of the compounds exhibited noticeable activity against platelet aggregation induced by arachidonic acid. Amongst them, two compounds 2e and 2f showed higher activity with IC
e comparison of the prepared derivatives indicated the existence of a lipophilic medium-sized group on the phenyl ring increased their activity. In addition, the docking studies confirmed this hydrophobic interaction in the lipophilic pocket of cyclooxygenase-1 enzyme suggesting that hydrophobicity of this region plays a pivotal role in the anti-platelet activity of these compounds. To prove this finding, the enzymatic evaluation with the target enzyme is required.
One of the most effective methods for the development of dendritic cell (DC)-based cancer immunotherapy is
pulsing of DCs with tumor cell lysates (TCLs). However, antitumor immune responses of DCs are significantly influenced by how TCLs were prepared. Here, we compared four strategies of TCL preparation derived from colon cancer cells, HT-29, for
maturation of DCs.
Peripheral blood monocytes were isolated from healthy volunteers and incubated with granulocyte macrophage colony-stimulating factor and interleukin (IL)-4 to differentiate into DCs in 10 days. Morphological properties, phenotype characteristics (i.e. CD83 and CD86), and cytokine production (i.e. IL-10 and interferon gamma) of DCs loaded with four different TCLs (i.e. freeze-thaw, hypochlorous acid (HOCl), hyperthermia, and UV irradiation) were evaluated.
HOCl preparations led to the generation of DCs with higher surface expression of maturation biomarkers (particularly CD83), while UV preparations resulted in DCs with lower levels of surface biomarkers compared to freeze-thawed preparations. The supernatant of DCs pulsed with HOCl preparation showed significantly higher levels of interferon gamma and lower levels of IL-10 compared with the other groups.
Our results suggest that pulsing DCs with HOCl preparation may be superior to other TCLs preparation strategies, possibly due to induction of rapid necrotic cell death.

Inflammatory bowel disease (IBD) is a chronic gastrointestinal disease characterized by the inflammation of the intestine. The available medicinal treatments for IBD are not efficacious enough since they exert various adverse effects. Therefore, the search for new therapeutic agents should be continued. The present study aimed to assess the anti-inflammatory effects of pregabalin on acetic acid-induced colitis in rats.
Using 2 mL of 3% acetic acid solution, colitis was intra-rectally induced in rats. Animals were randomly divided into 6 groups including the normal group, colitis control group, pregabalin treatment groups (30, 50, and 100 mg/kg; i.p., respectively), and dexamethasone treatment group (1 mg/kg; i.p.). Macroscopic, microscopic, and biochemical (myeloperoxidase, tumor necrosis factor-alpha, interleukin-6, and interleukin-1 beta) examinations were used to evaluate the efficacy of pregabalin in the inflamed colon.
All the applied doses of pregabalin significantly decreased the severity of macroscopic and microscopic colonic damages including ulcer severity, ulcer area, percentage of necrosis, and total colitis index compared to the colitis control group.
