35), but VJ (64.0±24.0s, p<0.001) and IM (144.9±55.4s, p=0.002) were faster. Number of bowel grasps as a measure for the risk of bowel lesions was similar for BMS (15.8±3.0) and PT (15.9±4.6, p=0.861), whereas VJ required less (14.1±3.4, p=0.004) and IM required more than BMS (22.2±6.9, p<0.001).

PT had higher accuracy than VJ and IM, and lower number of bowel grasps than IM. BMS shows great potential for more reliable LBLM. Until BMS is available in clinical routine, PT should be preferred for LBLM.

Contradictory evidence exists over the best approach for the management of submacular hemorrhage (SMH). In this study, we compared the outcomes of subretinal versus intravitreal injection of recombinant tissue plasminogen activator (r-tPA) and gas in cases of SMH secondary to age-related macular degeneration (AMD).

Twenty five eyes with SMH were retrospectively divided in 2 groups. Group A underwent vitrectomy, subretinal r-tPA and gas (Vitrectomy group, n = 14), and group B received intravitreal r-tPA and gas (Pneumatic group, n = 11). SMH displacement and change in subfoveal hemorrhage thickness (SFHT) at 1month post-op were assessed. Additionally, best corrected visual acuity (BCVA) and central retinal thickness (CRT) at the end of the 12month follow-up (FU) were analyzed. Clinical and epidemiological prognostic factors were tested.

Mean duration of SMH prior intervention was 8.2(± 7.3) days. Baseline BCVA was 1.53 ± 0.73 LogMAR, mean extension of SMH was 4.604 ± 2079μm and mean CRT pre-treatment was 795 ± 365μm. SMH displacement at 1month post-treatment was total in 9/14 versus 6/11 and partial in 4/14 versus 2/11 in Group A and Group B, respectively (Fisher's exact test p = 0.38). SFHT reduced by 404 ± 312μm in Group A versus 376 ± 405μm in group B (p = 0.86). BCVA improvement and reduction of CRT were highly significant at the end of FU (p = 0.002 and p < 0.001 respectively) but did not differ between the 2 groups. Only baseline BCVA and preoperative CRT proved to be significant prognostic factors for the final functional outcome (p = 0.013 and p = 0.047 respectively).

Both treatment options proved equal efficacy in displacing SMH in AMD. A multicenter trial may delineate a desirable algorithm of treatment.

Here, we report four families with germline DICER1 pathogenic variants in which one member in each family had a more complex phenotype, including skeletal findings, facial dysmorphism and developmental abnormalities. The developmental features occur with a variable expressivity and incomplete penetrance as also described for the neoplastic and dysplastic lesions associated with DICER1 variants. Whole exome sequencing (WES) was performed on all four cases and revealed no further pathogenic or likely pathogenic dominant, homozygous or compound heterozygous variants in three of them. Notably, a frameshift variant in ARID1B was detected in one patient explaining part of her phenotype. This series of patients shows that pathogenic DICER1 variants may be associated with a broader phenotypic spectrum than initially assumed, including predisposition to different tumours, skeletal findings, dysmorphism and developmental abnormalities, but genetic work up in syndromic patients should be comprehensive in order not to miss additional underlying /modifying causes.This paper deals with the optical and photophysical properties of dihydrophenanthro[9,10-e][1,2,4]triazine fluorescent dyes doped in Silicate based sol-gel and homo-poly methyl methacrylate (PMMA). Solid hosts were found to effect on the optical and photophysical parameters such as molar absorptivity, cross sections of singlet-singlet electronic absorption and emission spectra, excited state lifetime, quantum yield of fluorescence. The dipole moment of electronic transition, the length of attenuation and oscillator strength of electronic transition from So → S1 have been calculated. The dyes were pumped with different powers using 3rd harmonic NdYAG laser of 355 nm and pulse duration 8 ns, with a repetition rate at (10 Hz). Good photostability for compounds 1 and 2 were attained. It was decreased to 49% & 54% and 46% & 40% of the initial ASE of dyes in sol gel and PMMA, respectively, after 55,000 pumping pulses at (10 mJ/pulse). The dyes in sol-gel showed improved photostability compared with those in organic polymeric matrices.

The enzyme that catalyzes the last step in proline synthesis, δ

-pyrroline-5-carboxylate reductase, showed in most cases a distinct preference in vitro for NADPH as the electron donor.

A Zymomonas mobilis gene coding for a δ

-pyrroline-5-carboxylate reductase was cloned and heterologously expressed, and the recombinant protein was purified and characterized. The enzyme showed higher affinity to, and higher catalytic rate with NADH, with a specific activity of about 600 nkat (mg protein)

. The molecular basis of this feature was investigated by analysis of the dinucleotide binding domain in silico.

We postulate that the main determinants of coenzyme preference for P5C reductases are the length and the sequence of the motif A, whereas the overall sequence identity is insufficient to predict it a priori. Results are discussed in view of the obligately fermentative metabolism of this bacterium.

Lichen secondary metabolites have drawn considerable attention in recent years due to the limitations of current treatment options. Vulpinic acid (VA) obtained from Letharia vulpina lichen species exerts a remarkable cytotoxic effect on different cancer types. However, the therapeutic efficacy of VA in metastatic prostate cancer (mPC) cells has not been investigated. In the present study, we aimed to identify VA-mediated cytotoxicity in PC-3 mPC cells compared with control cells.

After identifying the cytotoxic concentrations of VA, VA induced apoptosis was analyzed by Annexin V, cell cycle, acridine orange and propidium iodide staining and RT-PCR analysis. read more Our findings showed that VA significantly decreased the viability of PC-3 cells (p < 0.01) and caused a considerable early apoptotic effects through G0/G1 arrest, nuclear blebbing and the activation of particularly initiator caspases.

Therefore, VA may be a potential treatment option for mPC patients. However, the underlying molecular mechanisms of VA-induced apoptosis with advanced analysis should be further investigated.

Prodiginines are bacterial red polypyrrole pigments and multifaceted secondary metabolites. These agents have anti-proliferative, immunosuppressive, antimicrobial, and anticancer effects. Recent analysis revealed that prodigiosin hypersensitizes Serratia marcescens to gamma radiation. In the present study, we report the cytotoxicity and genotoxicity properties of undecylprodigiosin and butylcycloheptylprodigiosin in the presence and absence of radiation through the MTT and alkaline comet experiments.

Findings demonstrated that undecylprodigiosin was at least a fivefold more cytotoxic at low radiation doses (1 and 3Gy) on both MCF7 and HDF lines rather than in the absence or high radiation doses (5Gy) (P value < 0.05). Although butylcycloheptylprodigiosin toxicity on MCF7 and HDF was dose-dependent, it was not influenced by any radiation doses (P value > 0.05). Comet findings confirmed that these compounds' genotoxicity is only dose-dependent. Radiation had no significant effects on DNA damage on any of the cells (P value > 0.05).

In general, it can be concluded that the prodiginines are cytotoxic agents that act as a double-edged sword, radiosensitizers and radio-protective, respectively at low and high radiation doses in cancer treatment process. As the results they could be used in antitumor therapies very soon.

COVID-19 affects all age groups with no single cure. The drug discovery, manufacturing, and safety studies require extensive time and sources and, therefore, struggled to match the exponential spread of COVID-19. Yet, various repurposed drugs (antivirals, immune-modulators, nucleotide analogues), and convalescent plasma therapy have been authorized for emergency use against COVID-19 by Food and Drug Administration under certain limits and conditions. The discovery of vaccine is the biggest milestone achieved during the current pandemic era. About nine vaccines were developed for human use with varying claims of efficacy. The rapid emergence of mutations in SARS-CoV-2, suspected adverse drug reactions of current therapies in special population groups and limited availability of drugs in developing countries necessitate the development of more efficacious, safe and cheap drugs/vaccines for treatment and prevention of COVID-19. Keeping in view these limitations, the current review provides an update on the efficacy and safety of the repurposed, and natural drugs to treat COVID-19 as well as the vaccines used for its prophylaxis.The paper reports on two experiments that investigate whether polarity, clause order and incentive influence derivation of Conditional Perfection in two types of inducements (promises and threats). Both experiments are designed as inference tasks, additionally measuring reaction times to inferences. The paper shows that the derivation of Conditional Perfection is endorsed in both types of inducements. However, the negative consequent bias (i.e. higher rates of Conditional Perfection in conditionals with a negative consequent than in conditionals with an affirmative consequent) and the double negation effect (i.e. slowdown of reaction times to Conditional Perfection with a double negation in a consequent) hold for threats, but not for promises. The paper also reveals a parallel double negation effect (i.e. facilitation of Conditional Perfection in conditionals with negation in both clauses) in threats, but not in promises. Last but not least, the paper demonstrates that the effect of clause order and incentive on the derivation of Conditional Perfection is rather moderate.
