The skin concentration of a substance after a topical application or exposure determines both local treatment outcomes and the dermal toxicity assessment of various products. However, quantifying the time course of those concentrations at skin effect sites, such as the viable epidermal, superficial dermis and appendages in humans is especially problematic in vivo, making physiologically based mathematical modelling an essential tool to meet this need. This work further develops our published physiologically based pharmacokinetic and COMSOL based dermal transport modelling by considering the impact of the superficial subpapillary dermal plexus, which we represent as two well stirred compartments. The work also studied the impact on dermal concentrations of subpapillary plexus size, depth, blood velocity and density of subpapillary plexus vessels. Sensitivity analyses are used to define the most important transport determinants of skin concentrations after topical application of a substance, with previously published results used to validate the resulting analyses. This resulting model describes the available experimental data better than previous models, especially at deeper dermal depths.Quasi-emulsion solvent-diffusion crystallization (QESD) is a type of spherical crystallization which can be used as a particle design method to improve the flowability and micromeritic properties of drugs or excipients. Spherical particles are generated by dispersing a solvent phase in an antisolvent so that a transient emulsion is formed. Within the droplets the material can crystallize and agglomerate into spherical, hollow particles. Surfactants, such as surface-active polymers like hypromellose, are often required to stabilize the quasi-emulsion. To gain further understanding for the role of the stabilizer, a new screening-method was developed which compared different surface active polymers in solution at similar dynamic viscosities rather than at a set concentration. The dynamic viscosities of a low-viscosity grade hypromellose solution used in the previous publications describing the QESD crystallization of metformin hydrochloride by the authors was used as a target value. QESD crystallizations of metformin hydrochloride (MF) and celecoxib showed that the type of stabilizer and whether it is dissolved in the solvent or antisolvent has an effect on the agglomerates. For MF, the type of hypromellose used can have a significant influence on the properties of the agglomerates. More polymers could be used to stabilize the transient emulsion of celecoxib than previously found in literature. Furthermore, QESD crystallizations seem to be more robust when the stabilizer is dissolved in the antisolvent, however this can lead to a reduced drug load of the agglomerates.
Hemifacial spasm (HFS) is a condition causing poor quality of life. Treatment with botulinum toxinA (BTX) injection is effective. Only one randomized controlled trial with a single-blind fashion has evaluated if oral injection is needed in HFS. The present study aimed to evaluate the necessity of oral BTX injection in HFS by a randomized, double-blind, placebo-controlled method.

We conducted a double-blind, placebo-controlled trial in patients with HFS who never received BTX treatment. Eligible patients randomly received either 15units of BTX around the eye and normal saline around the mouth (groupA) or 15units of BTX around both the eye and the mouth (groupB). The primary outcomes were self-reported symptoms and observed frequency of spasms, while the secondary outcome was the duration of improvement or the time between the injection and the recurrence of symptoms to the same condition as before treatment. Student ttest and survival analyses were used to compare the duration of symptoms between both groups. The mean changes were compared to secondary outcomes between the two groups.

There were 60 patients enrolled, half in each group. Baseline characteristics between both groups were similar. The mean (SD) of the duration of improvement in groupA and B was 22.97 (18.85) and 17.53 (14.90)weeks, respectively (p = 0.220). There was no difference between both groups by survival analysis. GroupB had a higher percentage of mouth improvement but there was no difference in the percentage of eye improvement, visual analog scale of eye and mouth spasm, or frequency of eye and mouth spasm. GroupB had a higher incidence of side effects particularly mouth drooping (30% vs 10%) than groupA (p = 0.053).

The mouth injection of BTX may not be necessary for HFS. It may be beneficial to reduce mouth symptoms with a higher rate of mouth drooping.

However, the effects and mechanism of autophagy after TBI remain unclear. This study aimed to investigate whether tetrandrine could ameliorate TBI through autophagy to reduce ferroptosis. A mice model for TBI was implemented. Behavioral and histomorphological experiments were performed to evaluate outcomes of the mice. The ferroptosis levels was detected by Perls staining. Enzyme-linked immunosorbent assay (ELISA) was applied to detect malondialdehyde (MDA), glutathione (GSH), and glutathione peroxidase 4 (GPX4) levels in the brain tissue. Western blot test was performed to detect Beclin 1, light chain 3 (LC3) II/I, p62, GPX4, SCL7A11, and ferritin heavy chain 1 (FTH1) levels, and the expression of LC3B, Beclin 1, GPX4, and FTH1 in the brain tissue was detected by immunofluorescence (IF). The behavioral and histomorphological results demonstrated that tetrandrine improved the neurological function and cerebral edema on days 1, 3, and 7 after TBI. The ELISA results suggested that tetrandrine reduced the MDA concentration and increased GSH concentration on days 1, 3, and 7 after TBI. IF staining and Perls staining reflected that tetrandrine promoted autophagy and inhibited ferroptosis on days 1, 3, and 7 after TBI, respectively. Tetrandrine further improved the neurological function, cerebral edema, autophagy, and ferroptosis on days 1, 3, and 7 after TBI after adding the autophagy inducer rapamycin. The effect of TET in alleviating TBI increased with the increase of time and dose. Tetrandrine ameliorated TBI by regulating autophagy to reduce ferroptosis, providing a new therapeutic strategy for TBI.
Concise and precise prognostic models are urgently needed due to the intricate genetic variations among hepatocellular carcinoma (HCC) cells. Disorder or change in glycolysis metabolism has been considered one of the "hallmarks" of cancer. However, the prognostic value of glycolysis-related genes in HCC remains elusive.

A multigene prognostic model was constructed by least absolute shrinkage and selection operator Cox regression analysis in the The Cancer Genome Atlas (TCGA) cohort with 365 HCC patients and validated in the International Cancer Genome Consortium (ICGC) cohort with 231 HCC patients. The Kaplan-Meier methodology and time-dependent receiver operating characteristic curve were employed to confirm its predictive capability. A predictive nomogram was established based on the stepwise multivariate regression model. The differential expression of prognostic genes between HCC tissues and normal tissues was verified by quantitative real-time polymerase chain reaction (PCR) and immunohistochemistry in an independent sample cohort with 30 HCC patients.

The glycolysis-related gene signature and the nomogram model exhibited robust validity in predicting prognosis. The risk score was an independent predictor for overall survival (OS). 5'-N-Ethylcarboxamidoadenosine agonist Expression levels of immune checkpoint genes and cell cycle genes were significantly elevated in the high-risk group. The high-risk group presented high levels of immune exclusion. The risk score can distinguish the effect of immunotherapy in the IMvigor210 cohort. The prognostic gene expression showed a significant difference between HCC tissues and adjacent nontumorous tissues in the independent sample cohort.

The currently established glycolysis-related gene signature can accurately predict prognosis and reflect immune status, which may be a therapeutic alternative.

Providers were also asked about potential barriers to implementation. The majority of participants stated they would be comfortable screening for suicide with the ASQ tool (78.9%; N = 15), that they would recommend the ASQ tool and the BSSA to colleagues (84.2%; N = 16), and that they were "satisfied" or "highly satisfied" with the ASQ and BSSA (88.2%; N = 13). Barriers to implementation reported included a lack of knowledge regarding suicide risk screening and lack of access to behavioral health resources. Education regarding the ASQ, the BSSA, and suicide risk screening are highlighted as crucial elements for future implementation.Aim of the present study was to evaluate the relationship between sensory sensitivity and autistic eating behaviours or Eating Disorders (EDs) symptomatology, in a group of 75 adults with Autism Spectrum Disorders (ASDs) without intellectual disabilities, through a series of self-report questionnaires. We found that, controlling for demographic and clinical features (i) hypersensitivity in the vision domain predicted higher levels of both EDs symptoms and autistic eating behaviours; (ii) hyposensitivity in the taste domain predicted higher levels of EDs symptoms. This gives preliminary evidence that not only in children diagnosed with ASDs, but even in adult individuals, the threshold of sensory sensitivity is associated with dysfunctional eating behaviours.Immune globulin (IG) is administered as measles postexposure prophylaxis (PEP) in people with primary immunodeficiency disorders or individuals not eligible for live virus vaccination. However, measles virus (MeV) neutralizing antibody (nAb) levels in plasma for fractionation and IG products fractionated thereof have declined. Here, the feasibility of producing a measles hyperimmune globulin (HIG) for PEP of high-risk individuals was investigated. Plasma samples (n = 384) were selected based on donor self-identification for previous MeV infection or vaccination, to determine the MeV-nAb content and compare it to the potency of plasma pools (n = 13) from the current IG manufacture. Convalescent donors have higher mean MeV-nAb concentrations (3.9 IU/mL) than vaccinated donors (2.5 IU/mL), as previously reported. However, their selection would only result in a 1.4-fold elevated nAb concentration compared to current plasma pools, which is not sufficient for HIG production. Interestingly, thirty-two donors (8%) had a MeV-nAb concentration of ≥ 8 IU/mL. The selective use of these plasma donations would result in sixfold higher plasma pool concentrations, which should permit the manufacture of the measles HIG. Further, the longitudinal analysis of a subset of individuals who repeatedly donated plasma at a high frequency revealed only a minor decline (~ 30%) of MeV-nAb levels. Repeat donations of such high-potency donors would thus facilitate the production of the measles HIG. Due to its markedly raised MeV-nAb concentration compared to standard IG, such preparation could significantly shorten infusion time and thus improve the treatment experience for both physicians and patients, especially infants.
