This study aimed to increase FXS solubility and bioavailability by optimizing sublingual fast-dissolving films (SFs) containing a selected FXS self-nano-emulsifying system (s-SNES) previously prepared by our team. The s-SNES was loaded into SFs by solvent casting technique. BTK inhibitor A full factorial design (32) was applied to study the effects of polymer and plasticizer types on mechanical characteristics and the dissolution profile of FXS from the SFs. Numerical optimization was performed to select the SF having highest desirability according to predetermined characteristics. The optimized SF (O-SF) contained 1 g of s-SNES, polyvinylpyrrolidone K30 (6%w/v), polyethylene glycol 300 (20%w/w of polymer wt.), and Avicel PH101 (0.5%w/v). O-SF showed good permeation of FXS through sheep sublingual tissue. Storage of O-SF for three months showed no significant change in the FXS dissolution profile. In-vivo performance of O-SF in rabbits was compared to that of oral marketed tablets (Staturic® 80 mg). A cross-over design was applied and pharmacokinetic parameters were calculated after ensuring absence of sequence effect. Statistical analysis revealed better performance for O-SF with significantly higher Cmax, AUC0-24, AUC0-∞, apparent t1/2 together with lower tmax, and apparent kel than marketed tablets. Relative bioavailability of O-SF compared to the marketed tablet was found to be 240.6%. This confirms the achievement of the study aims of improving dissolution rate and bioavailability of FXS using a patient-wise convenient formula.Acute bovine liver disease (ABLD) is a sporadic hepatic disease affecting cattle in southern Australia, characterized histologically by striking periportal hepatocellular necrosis. The cause of ABLD is unknown; however, the seasonality and acute presentation of outbreaks suggest mycotoxin involvement. We describe here the clinical and pathologic findings of ABLD in 45 naturally affected cattle from 13 outbreaks occurring from 2010 to 2019 in Victoria, Australia. Outbreaks occurred in herds located along the southern coastal plain of Victoria and were observed most frequently in lactating dairy cattle. Clinical signs commonly included a combination of mild photosensitization, progressive neurologic signs, and hypogalactia, which preceded death by ≤ 48 h. All affected animals had marked elevations in activities of glutamate dehydrogenase, aspartate aminotransferase, and gamma-glutamyl transferase. At autopsy, the most common lesions were serosal petechiae and/or gastrointestinal hemorrhage, and hepatomegaly with a pronounced hepatic reticular pattern. The principal histologic lesion was widespread-severe periportal hepatocellular coagulative necrosis and erythrocyte pooling-which often extended to massive necrosis. Lesions in other organs were uncommon. Our study of ABLD suggests involvement of a potent hepatotoxin that is either directly cytopathic or requires bioactivation by periportal-specific enzymes.Current treatments for osteoporosis and other bone degenerative diseases predominately rely on preventing further bone erosion rather than restoring bone mass, as the latter treatments can unintentionally trigger cancer development by undiscriminatingly promoting cell proliferation. One approach to circumvent this problem is through the development of novel chemical carriers to deliver drug agents specifically to bones. We have recently shown that carbon nanodots (C-dots) synthesized from carbon nanopowder can bind with high affinity and specificity to developing bones in the larval zebrafish. Larval bones, however, are physiologically different from adult bones in their growth, repair, and regeneration properties. Here we report that C-dots can bind to adult zebrafish bones and that this binding is highly specific to areas of appositional growth. C-dots deposition occurred within 30 minutes after delivery and was highly selective, with bones undergoing regeneration and repair showing higher levels of C-dots deposition than bones undergoing normal homeostatic turnover. Importantly, C-dots deposition did not interfere with bone regeneration or the animal's health. Together, our results establish C-dots as a potential novel vehicle for the targeted delivery of drugs to treat adult bone disease.
To understand how patients with cancer reacted to the coronavirus disease 2019 (COVID-19) pandemic and whether their quality of life (QoL) was affected.
In June 2020, 111 patients with cancer treated in the supportive care unit of a Comprehensive Cancer Center in Milan and 201 healthy controls from the general population were enrolled and assessed both quantitatively and qualitatively for fears and COVID-19-related beliefs as well as for QoL.
Fear of COVID-19 was significantly lower among patients (41% vs 57.6%;
= 0.007), as was fear of cancer (61.5% vs 85.6%;
< 0.001) and other diseases. The perceived risk of getting COVID-19 was lower among patients (25.2% vs 52.7%;
< 0.001), as was the belief of having been exposed to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) (18.1% vs 40.8%;
< 0.001). The physical component of QoL was better among the population (54.5 vs 43.8;
< 0.001); the reverse was true for patients' psychological well-being (44.6 vs 39.6;
< 0.001). The qualitative data supported such results, showing a reduced psychological effect on the patients with cancer compared to the controls. Various reasons explain this result, including the awareness of being treated for cancer and nevertheless protected against getting infected in a cancer center of public health reorganized to continue treating patients by protecting them and personnel from the risk of infection.
The experience of a cancer diagnosis, together with proper hospital reorganization, may act as protective factors from fears and psychological consequences of the COVID-19 outbreak.
